ITEM 2 - ACQUISITION OR DISPOSITION OF ASSETS

         GENERAL. On December 1, 1999, Isonics Corporation ("Isonics" or the
"Company") completed a sale of its depleted zinc (DZ) business to
Eagle-Picher Technologies, LLC for $8.2 million dollars, including $1.5
million to be paid over a period of three years, which amount is subject to
certain contingencies. Isonics received $6,730,303.00 from E-P at the
closing, of which approximately $1,150,570.00 was used to pay certain accrued
liabilities. DZ is used to prevent corrosion in nuclear power plants.
Corrosion is a cause of high radiation fields in nuclear power plants and can
result in radiation exposure to workers. DZ also reduces environmental
cracking in certain kinds of nuclear reactors which, if not controlled, can
require extremely costly repairs or possibly result in premature shutdown and
de-commissioning of the facility.

         The Agreement executed between Isonics and Eagle-Picher (E-P)
provides for: (1) Isonics' sale of the DZ Business to E-P for a purchase
price including approximately $6,700,000 in cash plus three additional
payments of $500,000 over a three year period, (2) for E-P's sale to Isonics
of 200 kilograms of Silicon-28 in consideration for a 42 month warrant grant
to E-P for the purchase of 4,000,000 shares of Isonics common stock at a
purchase price of $3.75 per share. The Warrant is subject to a registration
rights agreement.

         Related to, but separate from, the sale of the depleted zinc
business, Isonics contemporaneously signed a ten year supply agreement by
which Isonics will have the exclusive right to purchase quantities of
isotopically pure Silicon-28, Silicon-29 and Silicon-30 and a non-exclusive
right to purchase quantities of Carbon-12 and Carbon-13 produced by E-P from
its pilot plant under construction in Oklahoma for a ten year period. The
Supply Agreement locks in what Isonics believes is a favorable purchase price
for the isotopes. As partial consideration for the exclusivity provisions,
Isonics agreed to pay E-P a fee equal to 3% of the net revenues from all
sales made by Isonics of products incorporating Silicon-28, Silicon-29 or
Silicon-30 supplied by E-P. The ability of E-P to produce isotopes meeting
the specifications of the supply agreement is contingent upon E-P
successfully bringing its pilot production plant online as scheduled in March
of 2000.

         In addition, Isonics purchased 200 kilograms of Silicon-28 from E-P
in consideration of a warrant to purchase 4,000,000 shares of Isonics common
stock exercisable by E-P for $3.75 per share through May 30, 2003. Isonics
granted E-P certain registration rights related to the shares of its common
stock issuable upon exercise of the warrant. E-P has an obligation to deliver
the Silicon-28 during calendar year 2000 or, if it fails to do so, it will
reduce the warrant proportionately. One of the properties of isotopically
pure Silicon-28 is its high thermal conductivity, which Isonics is currently
developing for semiconductor applications.

         Isonics is an advanced materials and technology 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.

INFORMATION REQUIRED BY ITEM 701 OF REGULATION S-B.

         SECURITIES SOLD. The sale described in the preceding paragraphs
occurred on December 1, 1999. The securities sold consists of one restricted
warrant ("Warrant") to purchase 4,000,000 shares of restricted common stock
issued at an exercise price of $3.75 per share.

         UNDERWRITERS AND OTHER PURCHASERS.

         No underwriters, agents, or placement agents participated in the
private placement.

         The warrant was issued to a single accredited investor as
consideration for the purchase of assets.

         The Warrant was issued in consideration for the purchase of 200
kilograms of Silicon-28 pursuant to an Asset Purchase Agreement executed
between Isonics and E-P.

         The transactions were exempt from registration under the Securities
Act of 1933, as amended by reason of Sections 4(2) and 4(6) of the Securities
Act of 1933.

         Terms of conversion or exercise are as follows:

         The Warrant granted to E-P may be exercised to purchase 4,000,000
         shares of restricted common stock issued on a warrant-for-share basis
         with the Company's common stock (subject to dilution adjustment) for a
         purchase price of $3.75 per share through the expiration date, May 30,
         2003

         The Company also entered into a registration rights agreement
relating to the shares of common stock underlying the Warrant.

         The Company intends to use the 200 kilograms of Silicon-28 from the
issuance of the Warrant for the continued development and commercialization
of Silicon-28 wafers for the semiconductor industry.

                               ASSET PURCHASE AGREEMENT


      This ASSET PURCHASE AGREEMENT (this "Agreement") is made as of this
30th day of November 1999 by and among EAGLE-PICHER TECHNOLOGIES, LLC, a
limited liability company formed under Delaware law ("E-P"), EAGLE-PICHER
INDUSTRIES, INC., an Ohio corporation ("EPI"), and ISONICS CORPORATION, a
California corporation ("ISONICS").

                                   R E C I T A L S

A.    ISONICS has been engaged in the business of selling depleted zinc directly
      or indirectly to commercial and governmental operators of nuclear power
      plants as described in more detail in ISONICS's annual report on Form
      10-KSB for the year ended April 30, 1999 (the "DZ Business") and owns
      certain assets (including inventory and certain contract rights)
      associated with the DZ Business (which assets are more specifically
      described on SCHEDULE A);

B.    ISONICS desires to sell, assign and convey all of the Zinc Assets to E-P
      and EPI, and E-P and EPI are willing to purchase the Zinc Assets and
      assume certain specified liabilities relating to the DZ Business, all as
      more fully described and upon the terms and conditions contained in this
      Agreement (collectively referred to as the "DZ Transaction"); and

C.    ISONICS desires to purchase 200 kilograms of Silicon-28 from E-P (the

      NOW, THEREFORE, in consideration of the mutual covenants and agreements
of the parties contained herein, and other good and valuable consideration,
the receipt and sufficiency of which is hereby acknowledged, the parties,

                        PURCHASE AND SALE OF ZINC ASSETS

      2.1   ZINC ASSETS.  On the Closing Date and on the terms and subject to
the conditions set forth in this Agreement, ISONICS will sell, transfer,

<PAGE>

Liabilities (as defined in Section 2.2), and E-P and EPI, or one of them, as
they may direct, will purchase, acquire and accept from ISONICS, all right,
title and interest in and to the Zinc Assets.  Except for the express
representations and warranties set forth in this Agreement, the sale of the
Zinc Assets will be "as is, where is" and without warranties of
merchantability or fitness for any particular purpose, and FOB ISONICS'
facility in Golden, Colorado; E-P and EPI will pay for the packaging and
delivery of the Zinc Assets to E-P's facility.

      2.2   ASSUMED LIABILITIES.  Upon the terms of and subject to the
conditions set forth in this Agreement, E-P shall assume at Closing and
accept only the liabilities and obligations of ISONICS listed on SCHEDULE 2.2
to this Agreement (the "Assumed Liabilities").  Neither  E-P nor EPI shall
assume any other liabilities of ISONICS.

      2.3   PURCHASE PRICE.

            2.3(a).  Subject to adjustment as contemplated by Section 2.4, the
      aggregate consideration to be received by ISONICS for the Zinc Assets (the
      "Purchase Price") consists of (i) cash equal to (A) $5,000,000 (the "Cash
      Portion"), PLUS (B) an estimate of Net Current Asset Value (as calculated
      pursuant to Section 2.4(a) at the Closing Date); (ii) the Additional
      Payments described in Section 2.3(b) and (iii) the assumption by E-P of
      the Assumed Liabilities.

            2.3(b).  Subject to the terms and conditions set forth herein, the
      Purchase Price shall be payable as follows:

                  (i)   At the Closing, E-P and EPI, jointly and severally,
            shall pay ISONICS cash equal to the Cash Portion and the estimated
            Net Current Asset Value by wire transfer of immediately available
            funds to such account or accounts as ISONICS shall specify in
            writing at least two Business Days prior to Closing.

                  (ii)  FIRST ADDITIONAL PAYMENT.

                        (A)   Not later than November 30, 2000, E-P and EPI,
                  jointly and severally, will pay ISONICS $500,000, unless there
                  is a Supplier Non-Performance during the period from the date
                  hereof to November 30, 2000.  AO Techsnabexport/
                  Electrochemical Plant is the "Supplier."  The term  "Supplier
                  Non-Performance" is defined to mean the Supplier's failure to
                  supply to E-P or EPI, as the case may be, the quantities of
                  zinc oxide powder required by the Supply Contract upon the
                  terms and conditions, including price, set forth in the Supply
                  Contract, unless the reason for the Supplier's failure is a
                  breach of the Supply Contract by E-P or EPI, as the case may
                  be.  The term "Supply Contract" means that certain contract
                  #08843672/70034-02D dated February 10, 1997, as amended,
                  between ISONICS and the Supplier for the supply of zinc oxide
                  powder in accordance with the terms of such contract (which
                  contract will be assigned to E-P or EPI, as the case may be,
                  at the Closing).

                                      -2-
<PAGE>

                        (B)   If the Supplier partially performs under the
                  Supply Contract but such partial performance constitutes a
                  Supplier Non-Performance, the First Additional Payment will be
                  pro-rated, based on the amount of zinc oxide powder actually
                  provided by the Supplier upon the terms and conditions of the
                  Supply Contract divided by the amount of zinc oxide powder
                  required to be provided under the Supply Contract (the
                  "Additional Payment Pro-ration").

                        (C)   E-P or EPI, as the case may be, may only declare a
                  Supplier Non-Performance under this Section 2.3(b)(ii),
                  Section 2.3(b)(iii) or Section 2.3(b)(iv), or claim a partial
                  performance if E-P or EPI, as the case may be, gives ISONICS
                  prompt notice of and information with respect to the Supplier
                  Non-Performance and an opportunity for ISONICS to assist E-P
                  or EPI, as the case may be, in correcting or seeking to remedy
                  the Supplier Non-Performance.

            (iii)  SECOND ADDITIONAL PAYMENT.

                        (A)  Not later than November 30, 2001, E-P and EPI,
                  jointly and severally, will pay ISONICS an additional
                  $500,000, unless there is a Supplier Non-Performance for the
                  period from December 1, 2000 to November 30, 2001.

                        (B) If during the period for which the Second Additional
                  Payment is calculated, the Supplier partially performs under
                  the Supply Contract but such partial performance constitutes a
                  Supplier Non-Performance, E-P and EPI, jointly and severally,
                  will pay ISONICS an amount calculated pursuant to the
                  Additional Payment Pro-ration.

            (iv)  THIRD ADDITIONAL PAYMENT.

                        (A)  Not later than November 30, 2002, E-P and EPI,
                  jointly and severally, will pay ISONICS an additional
                  $500,000, unless there is a Supplier Non-Performance for the
                  period from December 1, 2001 to November 30, 2002.

                        (B) If during the period for which the Third Additional
                  Payment is calculated, the Supplier partially performs under
                  the Supply Contract but such partial performance constitutes a
                  Supplier Non-Performance, E-P and EPI, jointly and severally,
                  will pay ISONICS an amount calculated pursuant to the
                  Additional Payment Pro-ration.

      2.4   NET CURRENT ASSET VALUE AND CLOSING PURCHASE PRICE ADJUSTMENT.

                                      -3-
<PAGE>

            2.4(a).  Not later than five Business Days prior to the Closing
      Date, ISONICS shall prepare and submit to E-P a closing statement
      estimating Net Current Asset Value for the DZ Business (the "Estimated
      Closing Statement"), and setting forth, in reasonable detail, ISONICS'
      estimation of the inventory less accounts payable of the DZ Business as of
      the Closing Date  (the "Estimated Net Current Asset Amount").   For
      purposes of calculating the Estimated Net Current Asset Amount and the
      Final Net Current Asset Amount (as defined below), (x) inventory
      ("Inventory") shall be valued as set forth in SCHEDULE 2.4(a) and (y)
      accounts payable shall consist only of current accounts payable incurred
      in the ordinary course of the DZ Business ("Accounts Payable").  The
      Estimated Closing Statement shall be accompanied by such supporting
      documentation as E-P may reasonably request.

                  (i)   If E-P disputes the correctness of the Estimated Net
            Current Asset Amount, E-P shall (not later than the second Business
            Day prior to the Closing Date) notify ISONICS of its objections and
            shall set forth, in writing and reasonable detail, the reasons for
            E-P's objections and the amount E-P estimates for the Estimated Net
            Current Asset Amount.  If E-P and ISONICS differ on the amount of
            the Estimated Net Current Asset Value and are unable to resolve
            their differences prior to the Closing Date, the amount to be
            included in the Purchase Price will be the Estimated Net Current
            Asset Value as estimated by ISONICS.

                  (ii)  If E-P fails to deliver a notice of objections within
            the timeframe set forth in Section 2.4(a)(i), E-P shall be deemed to
            have accepted ISONICS' calculation for the purpose of the payment of
            the Purchase Price as of the Closing Date.

            2.4(b).  Promptly following the Closing Date, but in no event later
      than 60 days after the Closing Date, E-P shall prepare and submit to
      ISONICS a closing statement of Net Current Assets for the DZ Business (the
      "Closing Statement"), setting forth, in reasonable detail, E-P's
      calculation of the actual Inventory and Accounts Payable of the DZ
      Business as of the Closing Date  (the "Final Net Current Asset Amount").
      The Closing Statement shall be accompanied by such supporting
      documentation as ISONICS may reasonably request.

                  (i)   If ISONICS disputes the correctness of the Final Net
            Current Asset Amount, ISONICS shall notify E-P of its objections
            within 20 days after the receipt of the Closing Statement and shall
            set forth, in writing and reasonable detail, the reasons for
            ISONICS' objections.  E-P and ISONICS shall endeavor in good faith
            to resolve any disputed items within 20 days after E-P's receipt of
            ISONICS' notice of objections.  If they are unable to do so, E-P and
            ISONICS shall select a nationally known independent accounting firm
            (the "Independent Accountants") to resolve the dispute, and the
            determination of such firm in respect of the correctness of each
            item remaining in dispute shall be conclusive and binding on ISONICS
            and E-P.  ISONICS and E-P shall cooperate with the Independent
            Accountants and shall provide the Independent Accountants with

                                      -4-
<PAGE>

            such background materials and other information as the Independent
            Accountants shall request.  The fees and expenses, if any, of the
            Independent Accountants shall be paid one-half by ISONICS and
            one-half by E-P.

                  (ii)  If ISONICS fails to deliver a notice of objections
            within such time, ISONICS shall be deemed to have accepted E-P's
            calculation.

                  (iii) If the Final Closing Statement reflects a Net Current
            Asset Value higher than included in the Estimated Closing Statement,
            E-P and EPI, jointly and severally, will pay ISONICS the difference
            within seven Business Days; if the Final Closing Statement reflects
            a Net Current Asset Value lower than included in the Estimated
            Closing Statement, ISONICS will pay E-P or EPI, as they may direct,
            the difference within seven Business Days.  If there is any dispute
            as to the Final Closing Statement, final payment, if any, will be
            made within seven Business Days after the resolution of the dispute.

            2.4(c).  The Closing Statement and the Final Net Current Asset
      Amount shall be determined in accordance with GAAP, except that Inventory
      shall be valued as set forth in SCHEDULE 2.4(a).

      2.5   ALLOCATION OF PURCHASE PRICE.  E-P and ISONICS agree to allocate
the Purchase Price and the components of the Purchase Price consideration
among the Zinc Assets pursuant to the tax allocation schedule set forth on
SCHEDULE 2.5 attached hereto.  E-P and ISONICS shall not take any position on
their respective Tax Returns that is inconsistent with such allocation of the
Purchase Price and the components of the Purchase Price consideration
pursuant to SCHEDULE 2.5, and ISONICS and E-P shall prepare and timely file
such reports and information returns as may be required to report the
allocation of the Purchase Price pursuant to this Section 2.5.  Within 20
Business Days after the determination of the Final Net Current Asset Amount,
ISONICS and E-P shall adjust SCHEDULE 2.5 to be consistent with the amount
of, and the components of, the Final Net Current Asset Amount.

      2.6   ASSIGNMENT OF CONTRACTS AND RIGHTS.  Anything in this Agreement
to the contrary notwithstanding, this Agreement shall not constitute an
agreement to assign any Zinc Asset or any claim or right or any benefit
arising thereunder or resulting therefrom if an attempted assignment thereof,
without the consent of a third party thereto, would constitute a breach or
other contravention thereof or in any way would adversely affect the rights
of E-P or EPI thereunder.  ISONICS will use its best efforts to obtain the
consent of the other parties to any such Zinc Asset or any claim or right or
any benefit arising thereunder for the assignment thereof to E-P or EPI as
E-P or EPI may reasonably request.  If such consent is not obtained, or if an
attempted assignment thereof would be ineffective or would adversely affect
the rights of E-P or EPI or E-P or EPI would not in fact receive all such
rights, ISONICS and E-P or EPI will cooperate in a mutually agreeable
arrangement under which ISONICS would provide to E-P or EPI the benefits
thereunder in accordance with the intent of this Agreement, including
subcontracting, sub-licensing, or sub-leasing to E-P or EPI, or under which
ISONICS would enforce for the benefit of E-P or EPI any and all rights of
ISONICS against a third party thereto.

                                      -5-
<PAGE>

From and after the Closing, ISONICS will pay to E-P or EPI within five (5)
Business Days of receipt all monies received by ISONICS in respect of any
Zinc Asset or any claim or right or any benefit arising thereunder. The
covenants of each of ISONICS and E-P or EPI set forth in this Section 2.6
shall survive the Closing until the assignment or novation of all Contracts
that constitute a portion of the Zinc Assets to E-P or EPI.  Nothing in this
Section 2.6 will limit the applicability of the condition set forth in
Section 9.4.

      2.7   AVAILABILITY OF PERSONNEL.  ISONICS will make the services of
Boris Rubizhevsky available as an independent consultant at times and place
reasonably requested by E-P (not to exceed 160 hours in any 12 month period)
to assist E-P in its dealings with the Supplier.  E-P shall pay directly or
reimburse ISONICS for expenses incurred by Mr. Rubizhevsky in the performance
of his duties requested by E-P, and compensate ISONICS for Mr. Rubizhevsky's
services at the rate of $107 per hour.

                                      III.
                              SILICON TRANSACTION

      3.1   SILICON PURCHASE.

            3.1(a).  On the terms and subject to the conditions set forth in
      this Agreement and for the consideration set forth in Section 3.2, E-P
      will sell, transfer, assign and deliver to ISONICS, free and clear of any
      Encumbrance, and ISONICS will purchase, acquire and accept from E-P, all
      right, title and interest in and to 200 kilograms of Silicon-28 meeting
      the specifications set forth on SCHEDULE 3.1(a), and subject to the
      delivery obligations set forth in SCHEDULE 3.1(a) (the "Silicon
      Purchase").  The Silicon-28 included in the Silicon Purchase will be
      packaged in a manner meeting the regulations of the U.S. Department of
      Transportation for transportation over interstate highways and made
      available for ISONICS FOB E-P's facility in Oklahoma.  E-P represents and
      warrants that it will use all commercially reasonable efforts to cause its
      pilot plant to meet the delivery commitments for the Silicon-28 set forth
      on SCHEDULE 3.1(a) (including without limitation if necessary and if
      available on commercially reasonable terms obtaining enrichment of its
      Silicon-28 production to meet such specifications), which representation
      and warranty will survive the Closing until the delivery commitments have
      been met.  E-P will keep ISONICS informed of its progress in producing the
      Silicon-28 and will consult and co-operate with ISONICS in seeking to
      perform its obligations under this Section 3.1(a).  Notwithstanding the
      foregoing, E-P shall not be liable for any failure to meet such delivery
      commitments if and to the extent that such failure results from any fire,
      flood, windstorm, strike or labor unrest, shortage of raw materials, act
      of God or other cause beyond the reasonable control of E-P.

            3.1(b).  CONSIDERATION.  On the Closing Date, and only after the
      completion of the DZ Transaction between the Parties, ISONICS will pay E-P
      in full for the Silicon Purchase (for which E-P will receive payment in
      full upon receipt of the Warrant) by issuing to E-P the Warrant in the
      form attached hereto as SCHEDULE 3.1(b).

            3.1(c).  REMEDY.  Notwithstanding any other provision of this
      Agreement, ISONICS' sole remedy for any breach by E-P of its obligation
      under this ARTICLE III shall be as follows:  (i) If after using
      commercially reasonable efforts (including using third parties to enrich
      the Silicon-28 where reasonable), and after regular consultation with and
      advice from ISONICS, E-P's pilot plant is incapable of producing and
      beneficiating (or providing for the beneficiation of) Silicon-28, and if
      E-P gives written notice to such effect to ISONICS on or before March 31,
      2000, E-P may cancel its obligation to deliver Silicon-28 to ISONICS on or
      before December 31, 2000, in accordance with this Article III.  If E-P
      cancels its obligation under this Article III pursuant to this Clause
      3.1(c)(i), E-P must return the Warrant and the Registration Rights
      Agreement to ISONICS for cancellation.  In such case, E-P will be liable
      for no additional damages to ISONICS; and (ii) If E-P does not cancel its
      obligation under this Article III in accordance with Clause 3.1(c)(i), E-P
      must deliver the Silicon-28 to ISONICS in accordance with this Article III
      or be liable to ISONICS for damages in accordance with Section 12.2.


                                      IV.

      such indebtedness (other than intercompany indebtedness) shall be prepaid
      or otherwise retired in whole or in part prior to the date on which such
      indebtedness or portion thereof is due to be repaid, it being understood

      6.5   COVENANT NOT TO COMPETE.   ISONICS agrees that for a period
beginning on the Closing Date and ending on the fifth anniversary of the
Closing Date (the "Noncompete Period"), it will not directly or indirectly,
own, manage, operate, join, control or participate in the ownership,
management, operation or control of, any business whether in corporate,
limited liability company, proprietorship or partnership form or otherwise as
more than a five percent owner in such business if such business is
competitive with the DZ Business as of the Closing Date.  The parties hereto
specifically acknowledge and agree that the remedy at law for any breach of
the foregoing will be inadequate and that E-P, in addition to any other
relief available to it, shall be entitled to temporary and permanent
injunctive relief without the requirement of bond.  In the event that the
provisions of this Section 6.5 should ever be deemed to exceed the limitation
provided by applicable law, then the parties agree that such provisions shall
be reformed to set forth the maximum limitations permitted.

      6.6   CONFIDENTIALITY.  During the Noncompete Period, ISONICS will, and
will cause its Affiliates to, treat and hold as confidential any confidential
information relating to the operations or affairs of E-P or the DZ Business.
If ISONICS or any of its Affiliates is requested or required (by oral or
written request for information or documents in any legal proceeding,
interrogatory, subpoena, civil investigative demand or similar process or by
Applicable Law) to disclose any such confidential information then ISONICS
shall notify E-P promptly of the request or requirement so that E-P, at its
expense, may seek an appropriate protective order or waive compliance with
this Section.  If, in the absence of a protective order or receipt of a
waiver hereunder, ISONICS or any of its Affiliates is, on the advice of
counsel, compelled to disclose such confidential information, ISONICS or any
of its Affiliates, as the case may be, may so disclose the confidential
information, provided that ISONICS or any of its Affiliates, as the case may
be, shall use reasonable commercial efforts to obtain reliable assurance that
confidential treatment will be accorded to such confidential information.  No
obligation of confidentiality shall apply to any confidential information of
E-P that ISONICS (i) can reasonably demonstrate in writing was already known
or in ISONICS' possession, (ii) can reasonably demonstrate in writing was
developed independently by ISONICS or (iii) ISONICS rightfully receives from
a third party without knowledge of a violation of any obligation of
confidentiality, provided, however, that if ISONICS later learns that any
such information was received in violation of any obligation of
confidentiality, from that point ISONICS shall treat such information
pursuant to the terms of this Agreement.  In addition, no obligation of
confidentiality shall apply to any information that is known to, or becomes
generally available to, the public without breach of this Agreement.

      6.7   ACCESS TO INFORMATION; COOPERATION AFTER CLOSING.  On and after
the Closing Date, ISONICS shall, at E-P's expense, (i) afford E-P reasonable
access upon reasonable prior notice during normal business hours to all
employees, offices, properties, contracts, records, books and affairs of
ISONICS to the extent relating to the conduct of the DZ Business prior to the
Closing, and (ii) cooperate fully with E-P with respect to matters relating
to the conduct of the DZ Business prior to the Closing, including, without
limitation, in the defense or pursuit of any Zinc Asset or Assumed Liability
or any claim or action that relates to occurrences involving the DZ Business
prior to the Closing Date.

                         COVENANTS AND AGREEMENTS OF E-P

      7.1   CORPORATE AND OTHER ACTION.  E-P shall take all action, corporate
or otherwise, which is necessary or reasonably appropriate to complete the
Contemplated Transactions, including the execution and delivery of all
documents and instruments that are necessary to effect the Contemplated
Transactions.

      7.2   ASSUMED LIABILITIES.  E-P shall pay and discharge the Assumed
Liabilities in accordance with its normal business practices.

      7.3   CONFIDENTIALITY.  For a period of five years from and after the
Closing Date, E-P will, and will cause its Affiliates to, treat and hold as
confidential, any confidential information relating to the operations or
affairs of ISONICS other than the DZ Business or the Zinc Assets.  In the
event that E-P, or any of its Affiliates, is requested or required (by oral
or written request for information or documents in any legal proceeding,
interrogatory, subpoena, civil investigative demand or similar process or by
Applicable Law) to disclose any such confidential information then E-P shall
notify ISONICS promptly of the request or requirement so that ISONICS, at its
expense, may seek an appropriate protective order or waive compliance with
this Section.  If, in the absence of a protective order or receipt of a
waiver hereunder, E-P, or any of its Affiliates, is, on the advice of
counsel, compelled to disclose such confidential information, E-P, or its
Affiliates, as the case may be, may so disclose the confidential information,
provided that E-P, or its Affiliates, as the case may be, shall use
reasonable commercial efforts to obtain reliable assurance that confidential
treatment will be accorded to such confidential information.  No obligation
of confidentiality shall apply to any confidential information of ISONICS
that E-P (i) can reasonably demonstrate in writing was already known or in
E-P's possession, (ii) can reasonably demonstrate in writing was developed
independently by E-P or (iii) E-P rightfully receives from a third party
without knowledge of a violation of any obligation of confidentiality,
provided, however, that if E-P later learns that any such information was
received in violation of any obligation of confidentiality, from that point
E-P shall treat such information pursuant to the terms of this Agreement.  In
addition, no obligation of confidentiality shall apply to any information
that is known to, or becomes generally available to, the public without
breach of this Agreement.

      7.4   NONSOLICITATION.  In the event that the Closing does not occur
for any reason, for a period of one year after the termination of this
Agreement, without the prior consent of ISONICS, E-P will not solicit the
employment of any person who is employed by ISONICS; provided, that the
foregoing shall not apply to responses to or follow-up hiring in respect of
general solicitations or advertisements for job positions not specifically or
generally directed to any employee of ISONICS.

      7.5   AGREEMENT CONCERNING ACQUISITION AND VOTING OF ISONICS COMMON
STOCK OR DERIVATIVE SECURITIES.  E-P, on behalf of itself and its Affiliates,
agrees that it (including its

                                      -11-
<PAGE>

Affiliates) will not acquire a beneficial interest in shares of common stock
of ISONICS in public transactions or private transactions except pursuant to
the exercise of the Warrant.  In addition, to the extent E-P or any Affiliate
owns, or acquires any ISONICS common stock (whether through the exercise of
the Warrant or otherwise, whether or not in violation of this Agreement):

            7.5(a).  E-P will vote any and all Company Voting Securities owned
      of record by E-P, and shall cause any and all Company Voting Securities
      owned beneficially by E-P, to be voted with respect to the election or
      removal of directors of ISONICS in accordance with the recommendations of
      a majority of the Board of Directors of ISONICS;

            7.5(b).  E-P will not form, join, or in any other way participate in
      a partnership, pooling agreement, syndicate, voting trust, or other
      "group" with respect to Company Voting Securities or enter into any
      agreement or arrangement or otherwise act in concert with any other person
      for the purpose of acquiring, holding, voting, or disposing of Company
      Voting Securities.

            7.5(c).  E-P shall be present, in person or by proxy, at all
      meetings of stockholders of ISONICS so that any and all Company Voting
      Securities owned of record or beneficially owned by E-P may be counted for
      the purpose of determining the presence of a quorum at such meetings. E-P
      shall not directly or indirectly take any action, along or in concert with
      any other person to circumvent the limitations of this Agreement.

            7.5(d).  E-P will use its best efforts to cause its Affiliates to
      act in accordance with the requirements of Paragraphs (a), (b), and (c) of
      this Section 7.5 as though they were each a party to this Agreement and
      bound by such provisions.

These covenants shall survive the Closing or termination of this Agreement
for a period of two years.

      7.6   AGREEMENT NOT TO CAUSE A RULE 13e-3 TRANSACTION.  E-P agrees that
it will not take, directly or indirectly (and it will not cause or permit any
Affiliate to take, directly or indirectly) actions to cause ISONICS to
accomplish a going-private transaction or other transaction of the type
described in Rule 13e-3 under the Securities Exchange Act of 1934, as
amended. This covenant shall survive the Closing or termination of this
Agreement for a period of two years.

      7.7   COMPLIANCE WITH SEC REPORTING REQUIREMENTS.  E-P acknowledges
that the acquisition of the Warrant will result in it becoming the beneficial
holder of more than 10% of the outstanding common stock of ISONICS.  E-P
further acknowledges its understanding that the common stock of ISONICS is
registered under the Securities Exchange Act of 1934, as amended.  E-P hereby
covenants and agrees that it will comply with the reporting requirements of
Section 13(d) and Section 16(a) of the Securities Exchange Act of 1934 (and
the rules thereunder) to the extent such requirements are applicable to E-P
and its Affiliates.

                            SURVIVAL; INDEMNIFICATION

      8.1   SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS.  The
representations and warranties made in this Agreement by ISONICS and E-P,
respectively, shall survive the Closing until the second anniversary of
Closing (or, if applicable, for the period set forth in the particular
representation or warranty), provided that the representations and warranties
set forth in B2, B14 and C2 shall survive for the applicable statute of
limitations.

      8.2   INDEMNIFICATION.

            8.2(a).  E-P shall defend, hold harmless and indemnify ISONICS and
      its Affiliates (each a "Seller Indemnified Party") from and against any
      and all Damages to which a Seller Indemnified Party may become subject
      insofar as the Damages (or actions in respect thereof) arise out of or are
      based upon (i) any failure by E-P to perform its obligations under this
      Agreement; (ii) the failure of E-P to satisfy the Assumed Liabilities; or
      (iii) any breach by E-P of its representations, warranties, covenants and
      agreements set forth in this Agreement (provided that a notice
      contemplated by Section 8.3 of a claim for indemnification is provided to
      the Indemnitor (as defined in Section 8.3) on or prior to the time of the
      expiration of the applicable representation or warranty).

            8.2(b).  ISONICS shall defend, hold harmless and indemnify E-P and
      its Affiliates (each, a "Buyer Indemnified Party") from and against any
      and all Damages, to which a Buyer Indemnified Party may become subject,
      insofar as the Damages (or actions in respect thereof) arise out of or are
      based upon (i) any failure by ISONICS to perform its obligations under
      this Agreement; (ii) any breach by ISONICS of any of the representations,
      warranties, covenants and agreements set forth in this Agreement (provided
      that a notice contemplated by Section 8.3 of a claim for indemnification
      is provided to the Indemnitor on or prior to the time of the expiration of
      the applicable representation or warranty), (iii) any liability of ISONICS
      other than the Assumed Liabilities or (iv) any liability of ISONICS under
      Environmental Laws incurred prior to the Closing Date.

      8.3   PROCEDURES.

            8.3(a).  Promptly after receipt by a party eligible for
      indemnification under this ARTICLE VIII (an "Indemnified Party") of notice
      of the commencement of any action, arbitration proceeding, governmental
      investigation or any other claim (a "Third Party Claim"), the Indemnified
      Party shall, if a claim in respect thereof is to be made against a party
      liable for indemnification under this ARTICLE VIII (an "Indemnitor"),
      notify the Indemnitor of the commencement thereof; PROVIDED, HOWEVER, that
      the failure of the Indemnified Party to notify the Indemnitor shall not
      relieve the Indemnitor from any liability under this ARTICLE VIII, except
      to the extent and only to the extent it is proved that the Indemnitor
      suffered actual prejudice from the failure to notify in connection with or
      in defending against such Third Party Claim.

                                      -13-
<PAGE>

            8.3(b).  If any action is brought against an Indemnified Party and
      the Indemnified Party notifies the Indemnitor of the commencement thereof,
      the Indemnitor shall be entitled to participate in and, to the extent that
      the Indemnitor may wish, to assume the defense of the action, with counsel
      reasonably satisfactory to the Indemnified Party (who shall not, except
      with the consent of the Indemnified Party, be counsel to the Indemnitor),
      and after notice from the Indemnitor to the Indemnified Party of its
      election to assume the defense, the Indemnitor shall not be liable to the
      Indemnified Party under this ARTICLE VIII for any legal fees or legal
      expenses subsequently incurred by the Indemnified Party in connection with
      the defense thereof other than reasonable costs of investigation.
      Notwithstanding anything in this Section 8.3 to the contrary, if the
      Indemnitor does not assume the defense and control of any such Third Party
      Claim as provided in this Section 8.3, the Indemnified Party shall have
      the right to defend such Third Party Claim in such manner as it may deem
      appropriate.

            8.3(c).  The Indemnitor shall be authorized to consent to a
      settlement of, or the entry of any judgment arising from, any Third Party
      Claim, and the Indemnified Party shall consent to such settlement of, or
      the entry of any such judgment arising from, such Third Party Claim;
      provided, however, that the Indemnitor shall:

                  (i)   pay or cause to be paid all amounts arising out of such
            settlement or judgment concurrently with the effectiveness thereof;

                  (ii)  not encumber any of the assets of the Indemnified Party
            or agree to any restriction or condition that would apply to the
            Indemnified Party or to the conduct of the Indemnified Party"s
            business; and

                  (iii) obtain, as a condition of any settlement or other
            resolution, a complete release of each Indemnified Party.

            8.3(d).  Except to the extent of the foregoing, no settlement or
      entry of judgment in respect of any Third Party Claim shall be consented
      to by any Indemnitor or Indemnified Party without the express written
      consent of the other party.  If the Indemnified Party fails to give its
      consent to a proposed compromise or settlement of a claim that would
      otherwise be permitted pursuant to this Section 8.3, the Indemnitor shall
      have no obligation whatsoever to the Indemnified Party with respect to
      Damages related to such claim in an amount in excess of the proposed
      compromise or settlement.

            8.3(e).  The parties agree to cooperate fully with each other in
      connection with the defense, negotiation or settlement of any prospective
      claim and to provide each other with all materials, information and data
      that is reasonably requested by the other in connection with a prospective
      claim.

      8.4   LIMITATIONS.  Notwithstanding the foregoing, an Indemnitor shall
have no liability under this ARTICLE VIII for any breach of representation or
warranty unless and until the

                                      -14-
<PAGE>

aggregate amount of Damages directly or indirectly suffered or incurred by an
Indemnified Party equals or exceeds One Hundred Thousand Dollars ($100,000)
(the "Threshold Amount").  At such time as the aggregate Damages directly or
indirectly suffered or incurred by an Indemnified Party equals or exceeds the
Threshold Amount, the Indemnified Party shall be indemnified to the extent
such Damages exceed the Threshold Amount. Furthermore, an Indemnitor shall
have no liability under this ARTICLE VIII for any indirect or consequential
damages.

of the sale of the DZ Business to E-P will result in increased operating
losses and other impacts, none of which individually or in the aggregate will
constitute a Material Adverse Effect on ISONICS.

governmental consents, novations, waivers, authorizations and approvals
identified on SCHEDULE B2.2 OR C4 and shall have made all filings and given

            12.1(b).  by either E-P or ISONICS if there shall be any law or
      regulation that makes completion of the Contemplated Transactions illegal

<PAGE>

      this Agreement pursuant to this Section 12.1(c) if the Closing shall not
      have been completed by December 31, 1999, by reason of the failure of
      such party or any of its Affiliates to perform in any material respects
      any of its or their respective covenants or agreements contained in this
      Agreement.

Any party desiring to terminate this Agreement pursuant to this Section 12.1
shall give written notice of such termination to the other parties to this
Agreement.

by Section 12.1, such termination shall be without liability of any party (or
any Affiliate, shareholder, director, officer, employee, agent, consultant or
representative of such party) to any other party to this Agreement; provided,
however, that if the Contemplated Transactions fail to close as a result of a
breach by ISONICS on the one hand, or E-P on the other hand, such breaching
party shall be fully liable for any and all actual damages incurred or suffered
by the other party as a result of all such breaches.   Notwithstanding the
foregoing, the provisions of Sections 6.6, 7.3, 7.4, 7.5 and this Section 12.2
shall survive any termination hereof pursuant to Section 12.1.

      other controversies arising out of, or relating to, this Agreement or the
      Contemplated Transactions (hereinafter collectively referred to as a
      "Dispute") shall initially be submitted to a senior officer from each
      party for resolution by mutual agreement between said officers.  Any
      mutual determination by the senior officers shall be final and binding
      upon the parties.  However, should such senior officers fail to arrive at
      a mutual decision as to the Dispute within 20 days after notice to both
      parties of the Dispute, the parties shall then attempt to resolve such
      Dispute by mediation in accordance with the terms and provisions set forth
      in the following paragraph.

                                     -22-
<PAGE>

            13.13(b) .  MEDIATION.  Notice of the demand for mediation for any
      Dispute which has not been resolved in accordance with the previous
      paragraph shall be filed with the other party to this Agreement, and shall
      be made within a reasonable time after such party is permitted to mediate
      the Dispute as provided herein.  All mediation proceedings shall take
      place in Dallas, Texas and shall be conducted in accordance with rules
      mutually determined by the parties.  The mediator shall be an individual
      mutually selected by ISONICS and E-P, which individual shall (i) have at
      least 10 years experience in the discipline which is the subject of the
      Dispute, or (ii) be an attorney of at least 10 years of experience in the
      realm of business transactions or commercial litigation.  Any mutual
      decision by the parties pursuant to any such mediation shall be final and
      binding upon the parties.  However, should the parties fail to arrive at a
      mutual decision as to the Dispute within 30 days after commencement of the
      mediation proceedings, the parties shall then be entitled to refer such
      Dispute to arbitration as provided in the following paragraph.

            13.13(c) .  ADDITIONAL PROCEEDINGS.  To the extent that any Dispute
      continues to exist after the mediation provided for in the preceding
      paragraph, the parties agree to resolve the Dispute by binding
      arbitration, unless the remedy sought is injunctive relief.  Respecting
      any Disputes which ultimately become the subject of court proceedings
      wherein the remedy sought is injunctive relief, the parties irrevocably
      agree that (i) the venue and jurisdiction for such proceedings shall be in
      any court of competent jurisdiction, and (ii) trial by jury is waived by
      both parties.  Arbitration of disputes shall be conducted in Dallas, Texas
      and shall apply the substantive law governing this Agreement.  The
      arbitration proceedings will be conducted by a panel of three arbitrators
      in accordance with the Rules of Commercial Arbitration of the American
      Arbitration Association ("AAA") and under the professional administration
      of the AAA, except that the parties shall have the rights of discovery as
      to one another such as are provided by Federal Rules of Civil Procedure 26
      through 37 in effect at the time of the arbitration and rights of
      discovery as to third parties in effect at the time of the arbitration as
      are provided by law.  The arbitration award shall be binding upon the
      parties.

      qualified and in good standing as a foreign corporation authorized to do

      shares of Common Stock, no par value ("Common Stock"), of which 6,607,670
      shares are outstanding, and 10,000,000 shares of Preferred Stock, no par

      3.    SEC DOCUMENTS

            3.1   FILED DOCUMENTS.  ISONICS has filed all forms, reports and
      documents required to be filed by it with the Securities and Exchange
      Commission (the "SEC") since its formation (collectively, the "ISONICS SEC
      Reports").  As of their respective dates, except as set forth in SCHEDULE
      B3.1, the ISONICS SEC Reports filed prior to the date hereof (i) complied
      as to form in all material respects with the applicable requirements of
      the Securities Act, the Exchange Act, and the rules and regulations
      thereunder and (ii) did not contain any untrue statement of a material
      fact or omit to state a material fact required to be stated therein or
      necessary to make the statements made therein, in the light of the
      circumstances under which they were made, not misleading.  The
      representation in clause (ii) of the preceding sentence shall not apply to
      any misstatement or omission in any ISONICS SEC Report filed prior to the
      date of this Agreement which was superseded by a subsequent ISONICS SEC
      Report filed prior to the date of this Agreement.  No Company Subsidiary
      is required to file any report, form or other document with the SEC.
      Except as set forth in SCHEDULE B3.1 neither ISONICS nor any Company
      Subsidiary is a party or is subject to any note, bond, mortgage,
      indenture, contract, lease, license, agreement, understanding, instrument,
      bid or proposal that is required to be described in or filed as an exhibit
      to any ISONICS SEC Report that is not described in or filed as an exhibit
      to such ISONICS SEC Report as required by the Securities Act or the
      Exchange Act, as the case may be.  Except as disclosed on SCHEDULE B3.1,
      no event has occurred prior to the date hereof as a consequence of which
      ISONICS would be required to file a Current Report on Form 8-K pursuant to
      the requirements of the Exchange Act as to which such a report has not
      been timely filed with the SEC.  Any reports, statements and registration
      statements and amendments thereto (including, without limitation, Annual
      Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports
      on Form 8-K, as amended) filed by ISONICS with the SEC after the date
      hereof shall be provided to E-P no later than the date of such filing.

      of ISONICS included in or incorporated by reference into the ISONICS SEC
      Reports (including the related notes and schedules) fairly presents the
      consolidated financial position of ISONICS and the Company Subsidiaries as
      of its date, and each of the consolidated statements of income, retained
      earnings and cash flows of ISONICS included in or incorporated by
      reference into the ISONICS SEC Reports (including any related notes and
      schedules) fairly presents the results of operations, retained earnings or
      cash flows, as the case may be, of ISONICS and the Company Subsidiaries
      for the periods set forth therein (subject, in the case of unaudited
      statements, to normal year-end audit adjustments which would not be
      material in amount or effect), in each case in accordance with GAAP
      consistently applied during the periods involved, except as may be noted
      therein.  Neither ISONICS nor any of the Company Subsidiaries has any
      liabilities or obligations of any nature (whether accrued, absolute,
      contingent or otherwise) that would be required to be reflected on, or
      reserved against in, a balance sheet of ISONICS or in the notes thereto,
      prepared in accordance with GAAP consistently applied, except for (i)
      liabilities or obligations that were so reserved on, or reflected in
      (including the notes to), the consolidated balance sheet of ISONICS as of
      April 30, 1999;

      (ii) liabilities or obligations arising in the ordinary course of
      business since April 30, 1999 and (iii) liabilities or obligations which
      would not, individually or in the aggregate, have a Material Adverse
      Effect.

            3.3   ABSENCE OF CERTAIN CHANGES.  Since July 31, 1999, except as
      disclosed in the ISONICS 1934 Act Reports, there has not been (i) any
      event, occurrence, fact, condition, change, development or effect
      ("Event") that has had a Material Adverse Effect on ISONICS or the DZ
      Business; (ii) any declaration, payment or setting aside for payment of
      any dividend (except to ISONICS or a Company Subsidiary wholly owned by
      ISONICS) or other distribution or any redemption, purchase or other
      acquisition of any shares of capital stock or securities of ISONICS or any
      Company Subsidiary; (iii) any return of any capital or other distribution
      of assets to stockholders of ISONICS or any Company Subsidiary (except to
      ISONICS or a Company Subsidiary wholly owned by ISONICS); (iv) any
      acquisition (by merger, consolidation, acquisition of stock or assets or
      otherwise) of any person or business; (v) any other action or agreement or
      undertaking by ISONICS or any Company Subsidiary that, if taken or done on
      or after the date hereof would reasonably be expected to have a Material
      Adverse Effect; (vi) any material change in ISONICS' accounting
      principles, practices or methods; or (vii) any material loss or
      destruction of, or material amount of damage to, the Zinc Assets.

      4.    BOOKS AND RECORDS.  The regular books of account of ISONICS fairly
and accurately reflect all transactions since July 31, 1999, and are true,
correct and complete.

      5.    LAWSUITS AND PROCEEDINGS.  Except as set forth in the ISONICS 1934
Act Reports or on SCHEDULE B5, there is no suit, claim, action, civil or
criminal investigation or proceeding before or involving any court (at law or in
equity), arbitration or mediation panel, or Governmental Authority involving
ISONICS or any of Company Subsidiaries, and ISONICS is not aware of the
existence of facts or circumstances the consequence of which reasonably could be
expected to lead to any such suit, claim, action, audit or investigation,
pending or threatened against ISONICS or any of the Company Subsidiaries
including but not limited to, OSHA claims, workers' compensation claims,
employment discrimination claims, wage and hour claims, claims arising from or
relating to the violation of Environmental Laws or the handling of or disposal
of Hazardous Materials, claims arising out of laws, rules or regulations
relating to government contractors generally or under any government contract
laws or claims involving disputes between employees and ISONICS.  Neither
ISONICS nor any Company Subsidiaries is in default with respect to any decree,
injunction or other order of any court or Governmental Authority.

            6.1   Except as set forth in the ISONICS 1934 Act Reports or
      SCHEDULE B6.1, ISONICS has no Subsidiaries and does not otherwise directly
      or indirectly control any other business entity.

            6.2   Each Company Subsidiary is a corporation duly organized,
      validly existing and in good standing under the laws of the jurisdiction
      of its incorporation, has the corporate power and authority to own its
      properties and to carry on its business as it is now being conducted, and
      is duly qualified to do business and is in good standing in each
      jurisdiction in which the ownership of its property or the conduct of its
      business requires such qualification, except for jurisdictions in which
      such failure to be so qualified or to be in good standing would not,
      individually or in the aggregate, have a Material Adverse Effect.  The
      copies of the Certificates of Incorporation and Bylaws of ISONICS and the
      Company Subsidiaries previously made available to E-P are true and
      correct.

            6.3   Except as set forth in the ISONICS 1934 Act Reports SCHEDULE
      B6.3, ISONICS owns directly or indirectly all of the outstanding shares of
      capital stock (or other ownership interests having by their terms ordinary
      voting power to elect a majority of directors or others performing similar
      functions with respect to such Company Subsidiary) of each of the Company
      Subsidiaries.  Each of the outstanding shares of capital stock of each of
      the Company Subsidiaries is duly authorized, validly issued, fully paid
      and nonassessable, and is owned, directly or indirectly, by ISONICS.
      Except as set forth in SCHEDULE B6.3, each of the outstanding shares of
      capital stock of each Company Subsidiary is owned, directly or indirectly,
      by ISONICS free and clear of all liens, pledges, security interests,
      claims or other encumbrances other than liens imposed by local law which
      are not material.  There are no irrevocable proxies, voting agreements or
      similar obligations with respect to such capital stock of the Company
      Subsidiaries, and no equity securities or other interests of any of the
      Company Subsidiaries are or may become required to be issued or purchased
      by reason of any options, warrants, rights to subscribe to, puts, calls,
      reservation of shares of commitments of any character whatsoever relating
      to, or securities or rights convertible into or exchangeable for, shares
      of any capital stock of any Company Subsidiary, and there are no
      contracts, commitments, understandings or arrangements by which any
      Company Subsidiary is bound to issue additional shares of its capital
      stock, or options, warrants or rights to purchase or acquire any
      additional shares of its capital stock or securities convertible into or
      exchangeable for such shares.  The ISONICS 1934 Act Reports or SCHEDULE
      B6.3, sets forth the following information for each Company Subsidiary, if
      applicable:  (i) its name and jurisdiction of incorporation or
      organization; (ii) its authorized capital stock or share capital;
      (iii) the number of issued and outstanding shares of capital stock or
      share capital, and (iv) the percentage of such shares owned by ISONICS.

            6.4   Except as set forth in the ISONICS 1934 Act Reports or
      SCHEDULE B6.4, except for interests in the Company Subsidiaries, neither
      ISONICS nor any Company Subsidiary owns directly or indirectly any
      interests or investment (whether equity or debt) in any corporation,
      partnership, joint venture, business, trust or entity.

      7.    COMPLIANCE WITH LAWS.   Each of ISONICS and each Company
Subsidiary has, in all material respects, conducted its business (including
the DZ Business) and maintained its assets (including the Zinc Assets) in
compliance with all (and has not received notice of a claimed violation of
any) Applicable Laws and all orders, judgments and decrees of any court or
Governmental Authority applicable to, binding upon or affecting ISONICS or
any of its assets. All equipment owned, leased or used by ISONICS or any
Company Subsidiary, including the Zinc Assets, conforms in all material
respects with all Applicable Laws (including, without limitation all fire,
health and safety regulations). No ordinance or law, administrative
regulation or any other impediment of any kind prohibits, interferes with,
limits or impairs, or could, if enforced, prohibit, interfere with, limit or
impair the use, operation or maintenance of the Zinc Assets or the conduct of
the DZ Business.

      8.    LICENSES AND PERMITS.  ISONICS and the Company Subsidiaries
possess all licenses, permits, and other governmental consents, certificates,
approvals, or other authorizations (the "Permits") necessary for the
operation of their business at the locations and in the manner presently
operated.  Except as set forth on SCHEDULE B8, (a) ISONICS and each of the
Company Subsidiaries have complied with the terms and conditions of all
Permits and all such Permits are in full force and effect and (b) there has
occurred no event nor is any event, action, investigation or proceeding
pending or threatened which could cause or permit revocation or suspension of
or otherwise adversely affect the maintenance of any Permits.  Except with
respect to the Encumbrances created by the loan agreement with Coast Business
Credit (which will be repaid, and which Encumbrances will be released, at the
Closing with the proceeds to be paid to ISONICS), there are no provisions in,
or other Contracts to which ISONICS or any of the Company Subsidiaries is a
party relating to, any Permits which would preclude or limit E-P from
acquiring and operating the Zinc Assets substantially as they are now
operated.  ISONICS has delivered to E-P copies of all filings made by it in
connection with the TSCA registration of depleted zinc oxide.

      9.    INSURANCE.  ISONICS and each of the Company Subsidiaries have in
force and effect policies of fire, casualty, liability, worker's
compensation, life and other forms of insurance standard for its industries.
Neither ISONICS nor any of the Company Subsidiaries is in default with
respect to any provision contained in any insurance policy nor has ISONICS or
any of the Company Subsidiaries failed to give any notice or present any
claim thereunder in due and timely fashion and no cancellation or non-renewal
has been threatened or occurred with respect to any policy.  ISONICS and each
of the Company Subsidiaries have currently, and during each of its two past
fiscal years have had, in full force and effect, all insurance coverages
required by Applicable Law and have not been denied any insurance coverage
for which they have applied.

      10.   INTELLECTUAL PROPERTY.  The Yale License is the only Intellectual
Property material to ISONICS and the Company Subsidiaries.  To the knowledge
of ISONICS, the Yale License is valid and enforceable and does not infringe
upon, conflict with, or violate the rights of others, and neither ISONICS nor
any Company Subsidiary has received any notice or claim, and no proceedings
are pending or threatened, that the Yale License is not valid or enforceable
or that ISONICS or any Company Subsidiary has infringed upon, conflicted with
or violated any Intellectual Property of any third party.  Neither ISONICS
nor any Company Subsidiary has

                                   EXHIBIT B
<PAGE>

given any notice to a third party, and is not aware, that any Intellectual
Property has been infringed upon, conflicted with or violated. The use by
ISONICS and the Company Subsidiaries of the Yale License as it is presently
used does not violate the terms thereof and the Yale License is adequate and
enforceable and in full force and effect.

      11.   BROKER AND FINDER FEES.  Neither ISONICS nor any Company
Subsidiary has engaged any broker or finder in connection with this
transaction, and no action by any of the foregoing will cause or support any
claim to be asserted against E-P by any broker, finder or intermediary in
connection with the Contemplated Transactions.

the ISONICS 1934 Act Reports, to the knowledge of ISONICS:

      disposal, escape, dumping or release of any kind on, beneath or above such
      Property or into the environment surrounding such Property of any
      Hazardous Materials or any other similar event or condition which has
      given rise to or will give use to liability on the part of ISONICS or any
      Company Subsidiary.

      13.   ENVIRONMENTAL REPRESENTATIONS.  Except as set forth in SCHEDULE B13:

            13.1  There has been no past, and there is no current or anticipated
      storage, disposal, generation, manufacture, refinement, transportation,
      production or treatment of any Hazardous Materials at, upon or from such

            13.2  There are no claims, notices of violations, notice letters,

      Business, the other businesses of ISONICS or any Company Subsidiary, or
      any Property  in connection with any actual or alleged failure to comply
      with any requirement of any Environmental Law.

Assets, free and clear of all Encumbrances except for the Encumbrance to
Coast Business Credit (which will be released at Closing), and Encumbrances
for personal property taxes not yet due and payable.  The Zinc Assets

      20.   EMPLOYMENT OBLIGATIONS.  Except as described in the ISONICS 1934

material obligations, contingent or otherwise, under any employment,

      21.  CONTRACTS.  Except as set forth in the ISONICS 1934 Act Reports or

                          REPRESENTATIONS AND WARRANTIES
                                       OF E-P

      E-P hereby represents and warrants to ISONICS as follows:

      1.    ORGANIZATION AND GOOD STANDING.  E-P is a limited liability
company duly organized, validly existing and in good standing under the laws
of the State of Delaware and has full power and authority to carry on its
business as it is now being conducted.

      2.    EXECUTION AND EFFECT OF AGREEMENT.  E-P has the power and
authority to enter into this Agreement and to perform the obligations to be
performed by E-P hereunder, and the execution and delivery of this Agreement
and the completion of the Contemplated Transactions hereby have been duly
authorized by all necessary action.  This Agreement has been duly executed
and delivered by E-P and constitutes a legal, valid and binding obligation of
E-P, enforceable against E-P in accordance with its terms, subject to
limitations on enforceability under bankruptcy and insolvency laws and
principles of equity.

      3.    RESTRICTIONS.  Neither the execution and delivery of this
Agreement nor the completion of the Contemplated Transactions hereby will
violate any of the provisions of the Certificate of Formation and Operating
Agreement of E-P.

      4.    CONSENTS.  Except as set forth on SCHEDULE C4, no consent or
approval of any court, governmental agency or other public authority, or of
any other person, corporation or entity is required as a condition to (a) the
validity or enforceability of this Agreement or any other instruments to be
executed by E-P to effectuate this Agreement, or (b) the completion or
validity of any of the transactions contemplated by this Agreement, except
for consents or approvals contemplated by this Agreement.

      5.    LAWSUITS AND PROCEEDINGS.  There is no suit, claim, action, civil
or criminal investigation or proceeding before or involving any court (at law
or in equity), arbitration or mediation panel or Governmental Authority
involving E-P or any of its Affiliates and, to E-P's knowledge, no such
proceeding is threatened, that would limit or prohibit its ability to perform
its ability to execute, deliver and perform this Agreement and the
Contemplated Transactions.

      6.    BROKER AND FINDER FEES.  Neither E-P nor any Affiliate of E-P has
engaged any broker or finder in connection with this transaction, and no
action by E-P or any Affiliate will cause or support any claim to be asserted
against ISONICS by any broker, finder or intermediary in connection with the
Contemplated Transactions.

      7.    RISKS OF FUTURE OPERATIONS.  E-P understands that the future
conduct of ISONICS' business is dependent upon a number of factors, including
historic working capital shortages, an existing default in the indebtedness
owed to Coast Business Credit, and the other factors set forth in the ISONICS
SEC Reports and elsewhere herein, and there is no assurance  that ISONICS
will be able to conduct its operations as contemplated in this Agreement or
any other information given to E-P.  In that connection, E-P understands that
certain statements

                                   EXHIBIT C
<PAGE>

contained herein, in the ISONICS SEC Reports, and which have been given to
E-P using the terms "may", "expects to", and other terms denoting future
possibilities, are forward-looking statements.  The accuracy of these
statements cannot be guaranteed as they are subject to a variety of risks
which are beyond ISONICS' ability to predict or control.  These risks may
cause actual results to differ materially from the projections or estimates
contained in this report.  These risks include, but are not limited to, the
possibility that the described operations or other activities will not be
completed on economic terms, if at all, and the other risks described herein
and the other documents incorporated herein or attached hereto.  It is
important that E-P understands the significant risks which accompany the
establishment of a new business and the proposed conduct of ISONICS' future
operations.

      8.    REVIEW OF INFORMATION.

            8.1   E-P represents and warrants that it has reviewed the ISONICS
      SEC Reports and such other information regarding ISONICS which E-P, its
      management and advisors, have deemed necessary or appropriate in
      connection with the Silicon Purchase and the acquisition of the warrant to
      purchase ISONICS common stock.  E-P acknowledges that information about
      ISONICS is available on the EDGAR Web site maintained by the Securities
      and Exchange Commission (http://www.sec.gov), although all of such
      information is subject to the qualifications set forth therein.  E-P
      acknowledges that ISONICS will continue to file reports with the
      Securities and Exchange Commission and that such reports will contain more
      current information regarding ISONICS than set forth above.  E-P
      acknowledges that such information will be available on the Web sites
      described above, and ISONICS will provide E-P copies of such information
      upon telephonic or written request.

            8.2   E-P represents that it has conducted such due diligence
      investigation of the market for depleted zinc and the DZ Business, and
      that in determining to purchase the DZ Business it has relied solely on
      its own investigation into the DZ Business and on the express
      representations and warranties of ISONICS in this Agreement.

            8.3   ISONICS has given E-P the opportunity to ask questions of and
      to receive answers from persons acting on ISONICS' behalf concerning
      ISONICS, its business, management, financial condition, and the ISONICS
      SEC Reports, and the opportunity to obtain any additional information
      regarding ISONICS, its business and financial condition which ISONICS
      possesses or can acquire without unreasonable effort or expense including
      (without limitation) all minutes of meetings of the Board of Directors of
      the Company or committees thereof, and other relevant documents requested
      by E-P.  In addition, E-P has (or prior to the Closing will have)
      conducted such other financial or other inquiry as E-P deems necessary or
      appropriate in the conduct of E-P's due diligence investigation and has
      not relied on due diligence of any other party in connection herewith.

            8.4   E-P acknowledges and understands, however, that ISONICS has
      not authorized any person to make any statements on its behalf which would
      in any way contradict any of the information which ISONICS has provided to
      E-P in writing,

                                   EXHIBIT C
<PAGE>

      including the information set forth in this Agreement or documents which
      are incorporated herein, and E-P further represents to ISONICS that E-P
      has not relied upon any such representations regarding ISONICS, its
      business or financial condition, or this transaction in making any
      decision to acquire the Warrant or to complete the Contemplated
      Transactions.

            8.5   E-P has reviewed the terms of this Agreement and all of the
      documents delivered in connection herewith or otherwise referenced herein
      with its legal, investment, tax, and financial advisors, and E-P has also
      consulted with such advisors with regard to the advisability of this
      investment to the extent E-P deems such consultation to be appropriate.
      E-P acknowledges that ISONICS has advised E-P that it recommends that E-P
      obtain such advice and consultation.  E-P further acknowledges that it has
      neither sought nor received any advice from ISONICS or any of its agents
      or affiliates with respect to any aspect of this Agreement or completion
      of the Contemplated Transactions.

      9.     LACK OF LIQUIDITY.  E-P acknowledges and understands that
although ISONICS common stock is currently trading on the over-the-counter
market and is quoted on the OTC Bulletin Board operating by the National
Association of Securities Dealers, Inc. (the "OTCBB"), such market is
extremely limited and volatile, and the continuation of that market on the
OTCBB or elsewhere is dependent on a number of factors beyond the control of
ISONICS and, consequently, there can be no assurance that the market for
ISONICS's common stock will continue.  Because ISONICS's common stock is
traded on the OTCBB, many broker-dealers will not participate in the market
for ISONICS's common stock and those that do participate may do so only in
compliance with the limitations established by strict rules promulgated by
the SEC (including without limitation Rule 15c2-6) and the National
Association of Securities Dealers, Inc. (the "NASD"), which rules may change
from time-to-time as deemed necessary or appropriate by the SEC or the NASD
to protect the public interest as such agencies determine "public interest"
to be.

      10.   ACCREDITED INVESTOR.  E-P has reviewed the definition of the term
"accredited investor" contained in Section 2(a)(15) of the Securities Act and
in Rules 215 and 501(a) thereunder.  Based on that review and the advice of
its legal advisors, E-P represents and warrants that it is an accredited
investor as defined in those provisions.

      11.   INVESTMENT REPRESENTATION.  E-P is acquiring the Warrant pursuant
to this Agreement for its own account and not on behalf of any other Person
or entity, or with a view to or for sale in connection with any distribution
other than in accordance with federal and state securities laws.  E-P has
received all information regarding ISONICS that has been requested.  E-P
further represents that it has had an opportunity to ask questions and
receive answers from ISONICS regarding the terms and conditions of the
proposed acquisition of the Warrant. E-P has experience as an investor in
securities of companies and acknowledge that it can bear the economic risk of
its investment in the ISONICS Warrant. E-P has, by reason of its business or
financial experience or financial experience of its professional advisors who
are unaffiliated with, and who are not compensated by, ISONICS or any
Affiliate thereof, directly or indirectly, the capacity to protect its
interest in connection with the acquisition of the Warrant.  E-P has the

                                   EXHIBIT C
<PAGE>

financial capacity to bear the risk of its investment.

      12.   RESTRICTED NATURE OF UNDERLYING COMMON STOCK.  E-P understands
that the shares of ISONICS common stock issuable upon exercise of the Warrant
are not, and will not be, registered.  Therefore, E-P will only be able to
exercise the Warrant to the extent an exemption from registration for the
exercise exists under federal law and applicable state law at the time of
exercise. Consequently, should E-P exercise the Warrant E-P will be acquiring
shares of common stock which are "restricted" and E-P will be required to
execute an appropriate investment letter as a condition to the exercise of
the Warrant. ISONICS may, in its discretion, require E-P to make additional
representations and warranties which are, in its reasonable judgment,
necessary to establish the availability of an appropriate exemption from
registration.

      13.   LEGENDS AND STOP TRANSFER INSTRUCTION.

            13.1  The Warrant and any certificates representing shares of common
      stock issuable upon exercise of the Warrant will bear a legend
      substantially similar to the following:

      The securities represented by this certificate have not been registered
      under the Securities Act of 1933, as amended, or any state or foreign
      securities laws and are therefore (and will continue to be) restricted
      securities within the meaning of Rule 144 of the General Rules and
      Regulations promulgated under the Securities Act of 1933, as amended (the
      "Act"), and applicable state statutes.  The securities cannot be sold
      unless they are registered under the Act and any applicable state
      securities laws or unless an exemption from such registration requirements
      is available.  The availability of such an exemption must be established
      to the satisfaction of ISONICS.  Consequently, the holder must bear the
      economic risks of the investment in the securities for an indefinite
      period of time because they have not been registered under the Act or any
      state securities laws.  ISONICS is the only person which may register the
      securities under the Act and state securities statutes and ISONICS has not
      made any representations to the holder regarding the registration of the
      securities or compliance with Regulation A or some other exemption under
      the Act.  The holder will not sell or attempt to sell the securities
      without registration under the Act and any applicable state securities
      laws, unless exemptions from such registration requirements are available
      and the undersigned has satisfied ISONICS that an exemption is available
      for such sale.

            13.2   ISONICS shall have the right to issue stop transfer
      instructions to its transfer agent to bar the transfer of any of the
      certificates representing the Warrant and the ISONICS common stock
      issuable upon exercise of the Warrant except in accordance with the Act.

      14.   FULL DISCLOSURE.  The representations and warranties made herein
by E-P do not contain any untrue statement of material fact and do not omit
to state any material fact necessary to make any statement, in light of the
circumstances under which the statement is made, not misleading.

                                   EXHIBIT C

      be transferred except upon the conditions specified in this Warrant,
      and no transfer of this Warrant or such shares shall be valid or

      with.

      2.    EXERCISE OF WARRANT.

            2.1   EXERCISE IN FULL.  Subject to the provisions hereof, this
Warrant may be exercised in full by the Holder hereof by surrender of this
Warrant, with the form of subscription at the end hereof duly executed by such
Holder, to the Company at its principal office accompanied by payment, in cash
or by certified or official bank check payable to the order of the Company, in
the amount obtained by multiplying the number of shares of Common Stock called
for on the face of this Warrant (without giving effect to any adjustment
therein) by the Purchase Price per share.

            2.2   PARTIAL EXERCISE.  Subject to the provisions hereof, this
Warrant may be

                                      -2-
<PAGE>

exercised in part by surrender of this Warrant in the manner and at the place
provided in Section 2.1 except that the amount payable by the Holder upon any
partial exercise shall be the amount obtained by multiplying (a) the number
of shares of Common Stock (without giving effect to any adjustment therein)
designated by the Holder in the subscription at the end hereof by (b) the
Purchase Price per share.  No partial exercise may be accomplished for fewer
than 1,000,000 shares.  Upon any such partial exercise, the Company at its
expense will forthwith issue and deliver to or upon the order of the Holder
hereof a new Warrant or Warrants of like tenor, in the name of the Holder
hereof or (upon payment by such Holder of any applicable transfer taxes) as
such Holder may request, calling in the aggregate on the face or faces
thereof for the number of shares of Common Stock equal (without giving effect
to any adjustment therein) to the number of such shares called for on the
face of this Warrant minus the number of such shares designated by the Holder
in the subscription at the end hereof.

            2.3   EXERCISE BY SURRENDER OF WARRANT OR SHARES OF COMMON STOCK.
In addition to the method of payment set forth in Sections 2.1 and 2.2 and in
lieu of any cash payment required thereunder, the Holder of the Warrants
shall have the right at any time and from time to time to exercise the
Warrants in full or in part by surrendering shares of Common Stock or the
Warrant Certificate in the manner and at the place specified in Section 2.1
as payment of the aggregate Purchase Price per share for the Warrants to be
exercised.  The number of Warrants or shares of Common Stock to be
surrendered in payment of the aggregate Purchase Price for the Warrants to be
exercised shall be determined by multiplying the number of Warrants to be
exercised by the Purchase Price per share, and then dividing the product
thereof by an amount equal to the Market Price (as defined below).  As used
herein, the phrase "Market Price" at any date shall be deemed to be (i) if
the principal trading market for such securities is any exchange, the last
reported sale price, or, in case no such reported sale takes place on such
date, the last reported sale prices for the previous ten (10) trading days in
which a sale was reported, in either case as officially reported on any
consolidated tape, (ii) if the principal market for such securities is the
over-the-counter market, the high bid price on such trading days as set forth
by Nasdaq or, (iii) if the security is not quoted on Nasdaq, the high bid
price as set forth in the National Quotation Bureau sheet listing such
securities for such day.  Notwithstanding the foregoing, if there is no
reported closing price or high bid price, as the case may be, on any of the
ten trading days preceding the event requiring a determination of Market
Price hereunder, then the Market Price shall be determined in good faith by
resolution of the Board of Directors of the Company, based on the best
information available to it.

            2.4   EXERCISE PURSUANT TO EXEMPTION.  The Holder may only
exercise the Warrant if, at the time of exercise, there is an exemption
available for the exercise of the warrant established under federal and
applicable state laws regulating the offer and sale of securities.  The
Company agrees to cooperate with the Holder in establishing such exemption,
and the Company will provide the Holder with an investment letter prior to
the time of exercise to assist the Holder in establishing the availability of
appropriate exemptions.

      3.    DELIVERY OF STOCK CERTIFICATES, ETC., ON EXERCISE.  As soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within fifteen business days thereafter, the Company at its own expense
(including the payment by it of any applicable issue taxes) will

                                      -3-
<PAGE>

cause to be issued in the name of and delivered to the Holder hereof, or as
such Holder (upon payment by such Holder of any applicable transfer taxes)
may direct, a certificate or certificates for the number of fully paid and
non-assessable shares of Common Stock to which such Holder shall be entitled
upon such exercise, plus, in lieu of any fractional share to which such
Holder would otherwise be entitled, cash equal to such fraction multiplied by
the then current Market Price of one full share, together with any other
stock or other securities and property (including cash, where applicable) to
which such Holder is entitled upon such exercise pursuant to Section 4 or
otherwise.

            4.    ADJUSTMENT FOR DIVIDENDS AND STOCK SPLITS.  If the Company
shall at any time or from time to time while the Warrant is outstanding, pay
a dividend or make a distribution on its Common Stock in shares of Common
Stock, subdivide its outstanding shares of Common Stock into a greater number
of shares or combine its outstanding shares into a smaller number of shares
or issue by reclassification (or by way of a forward or reverse stock split)
of its outstanding shares of Common Stock any  shares of its  capital stock,
then the number of Warrant Shares purchasable upon exercise of the Warrant
and the Purchase Price per share in effect immediately  prior to the date
upon which such change shall become  effective, shall be adjusted by the
Company so that the Holder thereafter exercising the Warrant shall be
entitled to receive the number of shares of Common Stock or other capital
stock which the Holder would have received if the Warrant had been exercised
immediately prior to such event. Such adjustment shall be made successively
whenever any event listed above shall occur.  An adjustment shall become
effective immediately after the record date in the case of each dividend or
distribution and immediately after the effective date of each other event
which requires an adjustment.

      5.    MERGER.  If notice has been given as provided in Section 9, this
Warrant shall terminate upon the occurrence of a transaction described in
Section 9(b) with an entity which is not an Affiliate of the Company and in
which the stock of the Company is changed into the right to receive cash,
property or the securities of the other entity.

      6.    OTHER ADJUSTMENTS.

            6.1   GENERAL.  In any case in which Section 4 hereof is not
applicable, where the Company shall issue or sell shares of its Common Stock
after the Original Issue Date to any Affiliate of the Company (an ?Affiliate
Sale?) for a consideration per share less than the Purchase Price per share
then in effect (the "Prior Exercise Price") then the Purchase Price per share
in effect hereunder shall be decreased to an amount equal to the Prior
Exercise Price multiplied by a fraction, the numerator of which is the sum of
(x) the total number of shares of Common Stock outstanding immediately prior
to such issuance and (y) the number of shares of Common Stock which the
aggregate consideration received from Affiliates in the Affiliate Sale would
purchase at the Prior Exercise Price, and the denominator of which is the sum
of (a) the total number of shares of Common Stock outstanding immediately
prior to the Affiliate Sale plus (b) the number of shares of Common Stock
issued or deemed to be issued to Affiliates in the Affiliate Sale.  In the
event of an adjustment to the Purchase Price per share under this Section
6.1, the number of shares of Common Stock issuable upon exercise hereof shall
be increased so that the aggregate exercise price of this Warrant is not
reduced as a result of such reduction of

                                      -4-
<PAGE>

Purchase Price per share.

            6.2   CONVERTIBLE SECURITIES.  (a) In case the Company shall
issue or sell any securities convertible into Common Stock of the Company
which would result in an adjustment pursuant to Section 4 or 6.1, above
("Convertible Securities") after the date hereof, there shall be determined
the price per share for which Common Stock is issuable upon the conversion or
exchange thereof, such determination to be made by dividing (a) the total
amount received or receivable by the Company as consideration for the issue
or sale of such Convertible Securities, plus the minimum aggregate amount of
additional consideration, if any, payable to the Company upon the conversion
or exchange thereof, by (b) the maximum number of shares of Common Stock of
the Company issuable upon the conversion or exchange of all of such
Convertible Securities.

            (b)   If the price per share so determined is nominal or zero,
then this Warrant shall be adjusted pursuant to Section 4 above.  If the
price per share so determined is less than Prior Exercise Price and the
issuance is subject to Section 6.1 above, then the Warrant shall be adjusted
pursuant to Section 6.1 above, provided further, that upon the expiration of
such rights of conversion or exchange of such Convertible Securities, if any
thereof shall not have been exercised, the adjusted Purchase Price per share
shall forthwith be readjusted and thereafter be the price which it would have
been had an adjustment been made on the basis that the only shares of Common
Stock so issued or sold were issued or sold upon the conversion or exchange
of such Convertible Securities, and that they were issued or sold for the
consideration actually received by the Company upon such conversion or
exchange, plus the consideration, if any, actually received by the Company
for the issue or sale of all of such Convertible Securities which shall have
been converted or exchanged.

            6.3   RIGHTS AND OPTIONS.  (a)  In case the Company shall grant
any rights or options to subscribe for, purchase or otherwise acquire Common
Stock, there shall be determined the price per share for which Common Stock
is issuable upon the exercise of such rights or options, such determination
to be made by dividing (i) the total amount, if any, received or receivable
by the Company as consideration for the granting of such rights or options,
plus the minimum aggregate amount of additional consideration payable to the
Company upon the exercise of such rights or options, by (ii) the maximum
number of shares of Common Stock of the Company issuable upon the exercise of
such rights or options.

            (b)   If the price per share so determined is nominal or zero,
then this Warrant shall be adjusted pursuant to Section 4 above.  If the
price per share so determined is less than Prior Conversion Price and the
issuance is subject to Section 6.1 above, then the Warrant shall be adjusted
pursuant to Section 6.1 above, provided that, if such rights or options shall
by their terms provide for an increase or increases or decrease or decreases,
with the passage of time, in the amount of additional consideration payable
to the Company upon the exercise thereof, the adjusted Purchase Price per
share shall, forthwith upon any such increase or decrease becoming effective,
be readjusted and thereafter be the price which it would have been had an
adjustment been made on the basis that the only shares of Common Stock so
issued or sold were those issued or sold upon the exercise of such rights or
options and that they were issued or sold for the

                                      -5-
<PAGE>

consideration actually received by the Company upon such exercise, plus the
consideration, if any, actually received by the Company for the granting of
all such rights or options, whether or not exercised.

            (c)   The provisions of this Section 6.3 and Section 6.1 shall
not apply to any stock option, warrant or convertible security issued to an
Affiliate prior to the date hereof or any stock option hereafter issued to an
Affiliate at an exercise price per share not less than the Market Price on
the date of grant.

            6.4   SILICON PURCHASE.  If the Holder fails to perform in whole
or in part its obligations under Article III of the Asset Purchase Agreement
dated as of November 30, 1999 between the Holder and the Company, and such
failure continues for a period of 30 days after notice from the Company to
the Holder, the number of Underlying Securities shall be multiplied by a
fraction, the numerator of which is the quantity (in kiligrams) of Silicon-28
actually delivered in accordance with the provisions of such Article III and
the denominator of which is 200.

      7.    FURTHER ASSURANCES.  The Company will take all such actions as
may be necessary or appropriate in order that the Company may validly and
legally issue fully paid and non-assessable shares of stock upon the exercise
of all Warrants from time to time outstanding.

      8.    ACCOUNTANTS' CERTIFICATE AS TO ADJUSTMENTS.  In each case of any
adjustment or readjustment in the shares of Common Stock issuable upon the
exercise of the Warrants, the Company at its expense will promptly cause the
Company's regularly retained auditor to compute such adjustment or
readjustment in accordance with the terms of the Warrants and prepare a
certificate setting forth such adjustment or readjustment and showing in
detail the facts upon which such adjustment or readjustment is based, and the
number of shares of Common Stock outstanding or deemed to be outstanding.
The Company will forthwith mail a copy of each such certificate to each
Holder.

      9.    NOTICES OF RECORD DATE, ETC.  In the event of

            (a)   any taking by the Company of a record of the Holders of any
      class of securities for the purpose of determining the Holders thereof who
      are entitled to receive any dividend or other distribution, or any right
      to subscribe for, purchase or otherwise acquire any shares of stock of any
      class or any other securities or property, or to receive any other right,
      or

            (b)   any capital reorganization of the Company, any
      reclassification or recapitalization of the capital stock of the Company
      or any transfer of all or substantially all the assets of the Company to
      or consolidation or merger of the Company with or into any other Person,
      or

            (c)   any voluntary or involuntary dissolution, liquidation or
      winding-up of the Company,

                                      -6-
<PAGE>

then and in each such event the Company will mail or cause to be mailed to
each Holder of a Warrant a notice specifying

      (i)         the date on which any such record is to be taken for the
                  purpose of such dividend, distribution or right, and stating
                  the amount and character of such dividend, distribution or
                  right,

      (ii)        the date on which any such reorganization, reclassification,
                  recapitalization, transfer, consolidation, merger,
                  dissolution, liquidation or winding-up is to take place, and
                  the time, if any, as of which the Holders of record of
                  Underlying Securities (if the Warrant were exercised prior to
                  such date) shall be entitled to exchange their shares of
                  Underlying Securities for securities or other property
                  deliverable upon such reorganization, reclassification,
                  recapitalization, transfer, consolidation, merger,
                  dissolution, liquidation or winding-up, and

      (iii)       the amount and character of any stock or other securities, or
                  rights options with respect thereto, proposed to be issued or
                  granted, the date of such proposed issue or grant and the
                  Persons or class of Persons to whom such proposed issue or
                  grant is to be offered or made.

Such notice shall be mailed at least 20 days prior to the date therein
specified.

      10.   RESERVATION OF STOCK, ETC., ISSUABLE ON EXERCISE OF WARRANTS.
The Company will at all times reserve and keep available, solely for issuance
and delivery upon the exercise of the Warrants, all shares of Common Stock
(or other securities) from time to time issuable upon the exercise of the
Warrants.

      11.   LISTING ON SECURITIES EXCHANGES.  In furtherance and not in
limitation of any other provision of this Warrant, if the Company at any time
shall list any Common Stock on any national securities exchange and shall
register such Common Stock under the Exchange Act, the Company will, at its
expense, simultaneously list the Underlying Securities on such exchange or
Nasdaq, upon official notice of issuance upon the exercise of the Warrants,
and maintain such listing of all shares of Common Stock from time to time
issuable upon the exercise of the Warrants; and the Company will so list on
any national securities exchange or Nasdaq, will so register and will
maintain such listing of, any Other Securities if and at the time that any
securities of like class or similar type shall be listed on such national
securities exchange or Nasdaq by the Company.

      12.   EXCHANGE OF WARRANTS.  Subject to the provisions of Section 17,
upon surrender for exchange of any Warrant, properly endorsed, to the
Company, as soon as practicable (and in any event within three business days)
the Company at its own expense will issue and deliver to or upon the order of
the Holder thereof a new Warrant or Warrants of like tenor, in the name of
such Holder or as such Holder (upon payment by such Holder of any applicable
transfer taxes)

                                      -7-
<PAGE>

number of shares of Common Stock called for on the face or faces of the
Warrant or Warrants so surrendered.

      13.   REPLACEMENT OF WARRANTS.  Upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
any Warrant and, in the case of any such loss, theft or destruction, upon
delivery of an indemnity agreement reasonably satisfactory in form and amount
to the Company or, in the case of any such mutilation, upon surrender and
cancellation of such Warrant, the Company at is expense will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

      14.   WARRANT AGENT.  The Company may, by written notice to each Holder
of a Warrant, appoint an agent having an office in New York, New York or

Holder of this Warrant in the event of any default or threatened default by
the Company in the performance of or compliance with any of the terms of this
Warrant are not and will not be adequate, and that such terms may be
specifically enforced by a decree for the specific performance of any
agreement contained herein or by an injunction against a violation of any of
the terms hereof or otherwise.

      16.   NOTICES, ETC.  All notices and other communications from the
Company to the Holder of this Warrant shall be mailed by first class
registered or certified mail, postage prepaid, or overnight carrier service,
at such address as may have been furnished to the Company in writing by such
Holder, or, until an address is so furnished, to and at the address of the
last Holder of this Warrant who has so furnished an address to the Company.

      17.   COMPLIANCE WITH THE SECURITIES ACT OF 1933.  Any transfer of this
Warrant or the Underlying Securities must be made in conformity with the
Securities Act of 1933, as amended, and then only against receipt of an
agreement of such Person to whom such offer or sale is made to comply with
the provisions of this Section 17 with respect to any resale or other
disposition of such security.  The Company may cause the legend set forth on
the first page of this Warrant to be set forth on each Warrant or similar
legend on any security issued or issuable upon exercise of this Warrant,
unless counsel for the Company is of the opinion as to any such security that
such legend is unnecessary.

      18.   PAYMENT OF TAXES.  The Company will not be obligated to pay or
provide for any income or other taxes which are assessable or which may
accrue on the exercise of the Warrant.  The Holder shall be solely
responsible for income taxes due under federal or state law, if any such tax
is due.

      19.   OPTIONAL REDEMPTION OF WARRANTS

                                      -8-
<PAGE>

            (a)  The Company, at its option, may call the Warrants
represented by this Agreement, in whole or in part, for redemption upon not
less than 20 days' notice nor more than 60 days' notice at any time after the
Market Price shall have equaled or exceeded $7.50 per share for 20
consecutive trading days. The Redemption Price is and will be $.10 per
Warrant.

            (b)   In the event that fewer than all the outstanding Warrants
are to be redeemed, the shares to be redeemed will be determined pro rata or
by lot, in the sole discretion of the Company.

            (c)   The notice required by Subsection (a), above (the
"Redemption Notice"), must be in writing, and must set forth:  (i) the
Redemption Date (which may be no less than 20 days nor more than 60 days
after the notice); (ii) the address to which any notification of exercise of
the Warrant prior to the Redemption Date must be sent; and (iii) other
information the Company determines to include in such notification.

            (d)   On or before any Redemption Date, the Holder must either
(i) exercise the Warrant in accordance with the terms hereof; or (ii)
surrender the Warrant for redemption to the Company in accordance with the
terms of the Redemption Notice.

            (e)   On the Redemption Date, regardless whether the Warrants
have been surrendered for redemption, all Warrants issued pursuant to this
Agreement which are subject to redemption pursuant to the Redemption Notice
and which have not been properly exercised prior to the Redemption Date shall
be deemed cancelled and of no further force and effect.

            (f)   On the first business day following the Redemption Date,
the Company shall pay or deliver to any Holder who has not exercised the
Warrant in accordance with the terms thereof (or who has only exercised the
Warrant in part) and who has delivered the Warrant to the Company in
accordance with the terms of the Redemption Notice, the full Redemption Price
due such Holder in cash.

            (g)  If fewer than all the Warrants represented by any Warrant
Agreement are to be redeemed, a new Warrant shall be issued representing the
unredeemed Warrants, without cost to the Holder.

            (h)   If any Holder whose Warrants are called for redemption
fails to surrender the Warrant representing such Warrants, such Holder shall
not be entitled to receive payment of the Redemption Price until the Warrant
has been surrendered for cancellation.  Such Holder will not be entitled to
receive any interest on the Redemption Price from the Redemption Date.

      20.   MISCELLANEOUS.  This Warrant and any term hereof may be changed,
waived, discharged or terminated only by an instrument in writing signed by
the party against which enforcement of such change, waiver, discharge or
termination is sought.  This Warrant is being delivered in the State of
Colorado and shall be construed and enforced in accordance with and governed
by the laws of the State of Delaware.  The headings in this Warrant are for
purposes of

                                      -9-
<PAGE>

reference only, and shall not limit or otherwise affect any of the terms
hereof.

      21.   REGISTRATION, ETC.  The Holder shall have the rights to
registration of Underlying Securities issuable upon exercise of the Warrants
that are set forth in the Registration Rights Agreement, dated the date
hereof between the Company and the first Holder of this Warrant (the
"Registration Rights Agreement").

      22.   SALE OR EXERCISE WITHOUT REGISTRATION.  If, at the time of any
exercise, transfer or surrender for exchange of a Warrant or of Underlying
Securities previously issued upon the exercise of Warrants, such Warrant or
Underlying Securities shall not be registered under the Securities Act, the
Company may require, as a condition of allowing such exercise, transfer of
exchange, that the Holder or transferee of such Warrant or Underlying
Securities, as the case may be, furnish to the Company a satisfactory opinion
of counsel to the effect that such exercise, transfer or exchange may be made
without registration under the Securities Act, provided that the disposition
thereof shall at all times be within the control of such Holder or
transferee, as the case may be, and provided further that nothing contained
in this Section 21 shall relieve the Company from complying with any request
for registration pursuant to the Registration Rights Agreement.  The first
Holder of this Warrant, by acceptance hereof, represents to the Company that
it is acquiring the Warrants for investment and not with a view to the
distribution thereof.

      23.   COMPANY TO REAFFIRM OBLIGATIONS.  The Company will, at the time
of any exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing its continuing obligation to afford to such Holder
hereof, acknowledge in writing its continuing obligation to afford to such
Holder any rights (including, without limitation, any right to registration
of the Underlying Securities) to which such Holder shall continue to be
entitled after such exercise in accordance with the provisions of this
Warrant, provided that if the Holder of this Warrant shall fail to make any
such request, such failure shall not affect the continuing obligation of the
Company to offer such Holder any such rights.

      24.   EXTENDED EXPIRATION.  The right to exercise this Warrant shall
expire at 5:00 P.M., New York City time, on the Expiration Date, provided,
however, that if the Holders of Warrants issued hereunder have, in accordance
with the terms thereof, requested a registration statement pursuant to the
Registration Rights Agreement of ninety (90) days or more prior to the
Expiration Date and such registration statement has not become effective
prior to the Expiration Date then the right to exercise this Warrant shall be
extended and shall expire 30 days after the effective date of such
registration statement.  Alternatively, in the Company?s sole discretion, the
Company may redeem the Warrants in accordance with Section 19 above, but the
Redemption Price per Warrant in such case will be equal to the difference
between Market Price (as determined pursuant to Section 2.3 above) for the
period ending on the Expiration Date and the Purchase Price per share.

                            REGISTRATION RIGHTS AGREEMENT


       THIS REGISTRATION RIGHTS AGREEMENT (this "Agreement") is made and
entered into this 30th day of November, 1999, by and between Isonics
Corporation, a California corporation (the "Company"), and Eagle-Picher
Technologies, LLC, a Delaware limited liability company ("E-P").

       BACKGROUND.  The Company has entered into an Asset Purchase Agreement
dated as of November 30, 1999 (as amended, the "Asset Purchase Agreement")
with E-P pursuant to which the Company will issue to E-P a common stock
purchase warrant (the "Warrants"), entitling the holder thereof to purchase
four million (4,000,000) shares of common stock of the Company.  In addition,
simultaneously with the closing of the Asset Purchase Agreement, the Company
and E-P will enter into an "Isotope Supply Agreement."  An aggregate of
4,000,000 authorized but unissued shares of common stock, no par value per
share, of the Company ("Common Stock") are reserved for issuance upon
exercise of the Warrants.

       In consideration of the completion of the transactions set forth in
the Asset Purchase Agreement and the other documents and agreements entered
into at the completion of those transactions, and the mutual covenants and
agreements herein set forth, the parties to this Agreement hereby agree,
effective at the Effective Date (as defined below), subject to the terms and
conditions hereinafter set forth, as follows:

       1.     DEFINITIONS.  As used herein, unless the context otherwise
requires, the following terms have the following respective meanings:

       AGREEMENT:  As defined in the introductory paragraph of this Agreement.

       ASSET PURCHASE AGREEMENT:  As defined in the paragraph of this Agreement
entitled "Background."

       COMMISSION:  The U.S. Securities and Exchange Commission or any other
governmental authority at the time administering the Securities Act or the
Exchange Act.

       COMMON STOCK:  As defined in the paragraph of this Agreement entitled
"Background."

       COMPANY:  As defined in the introductory paragraph of this Agreement.

       EFFECTIVE DATE:  The date on which the Warrants are issued to E-P.

       E-P:  As defined in the introductory paragraph of this Agreement.

       EXCHANGE ACT:  The U.S. Securities Exchange Act of 1934, as amended, or
any similar or successor federal statute, and the rules and regulations of the

<PAGE>

Act shall include a reference to the comparable section, if any, of any such
similar or successor federal statute.

       PERSON:  A corporation, an association, a partnership, a limited
liability company, an individual, a joint venture, a trust or estate, an
unincorporated organization, or a government or any department or agency
thereof.

       REGISTRABLE SECURITIES:  (a) Any shares of Common Stock issued or
issuable upon exercise of the Warrant and (b) any securities issued or
issuable with respect to any Common Stock referred to in the foregoing
clauses by way of stock dividend or stock split or in connection with a
combination of shares, recapitalization, merger, consolidation or other
reorganization or otherwise. As to any particular Registrable Securities,
once issued, such securities shall cease to be Registrable Securities when
(v) they may be sold without restriction pursuant to Rule 144(k) (or any
successor provision) under the Securities Act, (w) a registration statement
with respect to the sale of such securities in the United States shall have
become effective under the Securities Act and such securities shall have been
disposed of in accordance with such registration statement, (x) they shall

the Securities Act, (y) they shall have been otherwise transferred, new
certificates for them not bearing a legend restricting further transfer shall

not require registration or qualification under the Securities Act or any
similar state law then in force, or (z) they shall have ceased to be
outstanding.  While the Warrants outstanding from time to time are not
Registrable Securities for the purpose of registration, holders of Warrants
shall, for purposes of giving of notices or the calculation of percentages of
Registrable Securities, be treated as the holders of the Registrable
Securities issuable upon exercise of their Warrants.  In addition, for
purposes of calculation of percentages of Registrable Securities, all
Warrants shall be treated as if they were the number of shares of Common
Stock which may be purchased upon exercise thereof.

"Registrable Securities" in the registration rights agreement dated the 29th
day of July, 1999, by and among the Company, Adam Smith & Company, Inc.

the holder or holders of the Registrable Securities being registered.

       SECURITIES ACT:  The U.S. Securities Act of 1933, as amended, or any
similar or successor federal statute, and the rules and regulations of the
Commission thereunder, all as the same shall be in effect at the time.

reference to the comparable section, if any, of any such similar or successor
federal statute.

       WARRANTS:  As defined in the paragraph of this Agreement entitled
"Background."

       2.     Registration under Securities Act

       2.1.   (a) REGISTRATION ON REQUEST.  Upon the written request of E-P
which can only be made after one year following the date of this Agreement
(or, if earlier, commencing on the date the Company calls the Warrants for
redemption pursuant to Section 19 of the Warrants), or the holder or holders
of a majority or more of the Registrable Securities, that the Company effect
the registration of all or part of such holders' Registrable Securities under
the Securities Act in connection with a sale of such shares in the United
States and specifying the intended method of disposition thereof (including
whether or not such disposition is intended to be effected as an underwritten
offering), the Company will promptly give written notice of such requested
registration to all other holders of Registrable Securities and thereupon the
Company will use its best efforts to effect the registration under the
Securities Act of:

                     (i)    the Registrable Securities which the Company has
       been so requested to register by the holder or holders submitting the
       request, and

                     (ii)   all other Registrable Securities which the Company
       has been requested to register by the holder or holders thereof by
       written request given to the Company within fifteen (15) days after the
       giving of such written notice by the Company (which request shall specify
       the intended method of disposition of such Registrable Securities), all
       to the extent requisite to permit the disposition (in accordance with the
       intended methods thereof as aforesaid) of the Registrable Securities so
       to be registered.

              (b)    PRIORITY IN REQUESTED REGISTRATIONS.  If a requested
registration pursuant to this Section 2.1 involves an underwritten offering,
and the managing underwriter shall advise the Company in writing (with a copy
to each holder of Registrable Securities requesting registration) that, in
its opinion, the number of Registrable Securities and other securities of the
Company held by any other party requested to be included in such registration
exceeds the number which can be sold in (or during the time of) such offering
within a price range acceptable to the holders of a majority (by number of
shares) of the Registrable Securities requested to be included in such
registration, the Company will include in such registration all Registrable
Securities and Registrable Securities - July 1999 requested to be included in
such registration (unless the provisions of the following sentence apply) and
will include in such registration other securities of the Company (including
any securities proposed to be issued and sold by the Company) held by any
other party only to the extent that the number of


                                      -3-
<PAGE>

shares which the Company is advised can be so sold in (or during the time of)
such offering exceeds the number of Registrable Securities and Registrable
Securities - July 1999 to be included in such registration.    If, after
application of the preceding sentence, the number of Registrable Securities
and Registrable Securities - July 1999 still exceed such maximum number, such
Registrable Securities and Registrable Securities - July 1999 will be
included in such registration only to the extent of the number of shares
which the Company is advised can be so sold in (or during the time of) such
offering; the Registrable Securities and the Registrable Securities - July
1999 to be included in such registration shall be taken up pro rata from the
holders of Registrable Securities and the Registrable Securities - July 1999
requesting such registration on the basis of the percentage of Registrable
Securities and Registrable Securities - July 1999 requested to be included in
such registration; and all shares proposed to be sold by the Company or any
other party shall be deleted from such registration prior to effecting any
reduction of Registrable Securities and Registrable Securities - July 1999
under this paragraph (b).

              (c)    REGISTRATION STATEMENT FORM.  Registrations under this
Section 2.1 shall accomplished by the Company on such appropriate
registration form of the Commission  (i) for which the Company qualifies, and
which the Company's counsel (after consultation with counsel or counsels for
the holders of the Registrable Securities) deems appropriate, and (ii) as
shall permit the disposition of such Registrable Securities in accordance
with the intended method or methods of disposition specified in the request
for such registration. The Company agrees to include in any such registration
statement all information as to the holders of the Registrable Securities to
be registered which the holders of the Registrable Securities being
registered shall reasonably request or which shall be required by applicable
law.

              (d)    EXPENSES.  Except as provided in paragraph (g) of this
Section 2.1 the Company will pay all Registration Expenses incurred in
connection with any registration requested pursuant to this Section 2.1 which
the Company is obligated to effect, whether or not such registration is
effected.

              (e)    EFFECTED REGISTRATION STATEMENT.  A registration
requested pursuant to this Section 2.1 shall not be deemed to have been
effected unless a registration statement with respect thereto has become
effective except:  (i) if the registration statement is withdrawn prior to
its effectiveness pursuant to the request of a majority of the holders of
Registrable Securities who have requested the inclusion in such registration
statement of some or all of their Registrable Securities or one or more of
the holders of Registrable Securities have not paid the Registration Expenses
relating thereto in accordance with paragraph (g) of this Section 2.1, (ii)
if, after the registration statement has become effective, such registration
is interfered with by any stop order, injunction or other order or
requirement of the Commission or other governmental agency or court for any
reason, and such stop order, injunction or other order or requirement results
from any action or inaction of a holder or holders of Registrable Securities,
or (iii) if the conditions to closing specified in the purchase agreement or
underwriting agreement entered into in connection with such registration are
not satisfied due to a failure by a holder of Registrable Securities to
satisfy a condition required to be satisfied by such holder pursuant to the
purchase agreement or underwriting agreement and one or more of the holders
of Registrable Securities have not paid the Registration Expenses relating
thereto in accordance with paragraph

                                      -4-
<PAGE>

(g) of this Section 2.1.

              (f)    SELECTION OF UNDERWRITER.  If a requested registration
pursuant to this Section 2.1 involves an underwritten offering, the
underwriter or underwriters thereof shall be selected by the holders of a
majority of the Registrable Securities to be so registered.

              (g)    LIMITATION ON REGISTRATIONS.  The Company's obligations
under this Section 2.1 shall be limited to effecting a single registration
within the meaning of paragraph (e) of this Section 2.1; provided, however,
that (i) if all of the holders who have requested the inclusion of
Registrable Securities held by them in a registration requested under this
Section 2.1 withdraw such request prior to the time the registration
statement has become effective and any or all of such persons pay all
Registration Expenses relating thereto, such proposed registration shall not
count as the registration provided for by this Section 2.1; (ii) if a
registration is deemed to be effected pursuant to paragraph (e) of this
Section 2.1 because a condition to closing specified in the purchase
agreement or underwriting agreement entered into in connection with such
registration is not satisfied due to a failure by a holder of Registrable
Securities to satisfy a condition required to be satisfied by such holder
pursuant to such agreement and one or more of the holders of Registrable
Securities elects to pay (and shall actually have paid) all Registration
Expenses relating to the registration statement, such registration shall not
count as the registration provided for by this Section 2.1; and (iii) if as a
result of the application of the last sentence of Section 2.1(b), less than
67% of the number of Registrable Securities requested to be included in such
registration were included, such registation shall not count as the
registration provided for by this Section 2.1..

              (h)    COMPANY'S RIGHT TO DELAY REGISTRATION.  Notwithstanding
the foregoing provisions of this Section 2.1, the Company shall not be
obligated to effect a registration pursuant to this Section 2.1 within a
period of one (1) year after the effective date of a registration statement
previously filed as a result of a request pursuant to this Section 2.1.  In
addition, if the Company has issued and sold to the public, pursuant to a
registration statement filed under the Securities Act, any of its securities
within three (3) months prior to the date of its receipt of a request for
registration pursuant to this Section 2.1, and the Company's investment
banker has advised the Company in writing that the registration of
Registrable Securities would materially adversely affect the market for the
Common Stock, the Company shall have the right, which may not be exercised
more than once in a twelve (12) month period, to delay the requested
registration of Registrable Securities for such period as the investment
banker may so advise, but no more than one hundred twenty (120) days after
the date on which such request was made.

              (i)    LIMITATION ON SALES.  Notwithstanding the foregoing
provisions of this Section 2.1, no Registrable Securities may be sold
pursuant to a registration requested under this Section 2.1 until twelve (12)
months after the date of this Agreement.

       2.2.  INCIDENTAL REGISTRATION.


                                      -5-
<PAGE>

              (a)    RIGHT TO INCIDENTAL REGISTRATION.  If the Company at any
time after twenty-four (24) months from the date of this Agreement proposes
to register any of its securities under the Securities Act (other than by a
registration on Form S-8 or Form S-4 or any successor or similar form and
other than pursuant to Section 2.1 of this Agreement), whether or not for
sale for its own account, it will each such time give prompt written notice
to all holders of Registrable Securities of its intention to do so and of
such holders' rights under this Section 2.2.  Upon the written request of any
such holder made within fifteen (15) days after any such notice (which
request shall specify the Registrable Securities intended to be disposed of
by such holder and the intended method of disposition thereof), the Company
will use its best efforts to effect the registration under the Securities Act
in connection with a sale of such shares in the United States of all
Registrable Securities which the Company has been so requested to register by
the holders of Registrable Securities, to the extent requisite to permit the
disposition (in accordance with the intended methods thereof as aforesaid) of
the Registrable Securities so to be registered, provided that if, at any time
after giving written notice of its intention to register any securities and
prior to the effective date of the registration statement filed in connection
with such registration, the Company shall determine for any reason, the
Company may, at its election, give written notice of such determination to
each holder of Registrable Securities and, thereupon, (i) in the case of a
determination not to register, shall be relieved of its obligation to
register any Registrable Securities in connection with such registration (but
not from its obligation to pay the Registration Expenses in connection
therewith), without prejudice, however, to the rights of any holder or
holders of Registrable Securities entitled to do so to request that such
registration be effected as a registration under Section 2.1 above, and (ii)
in the case of a determination to delay rgistering, shall be permitted to
delay registering any Registrable Securities for the same period as the delay
in registering such other securities.  No registration effected under this
Section 2.2 shall relieve the Company of its obligation to effect any
registration upon request under Section 2.1 above.  The Company will pay all
Registration Expenses in connection with each registration of Registrable
Securities requested pursuant to this Section 2.2.

              (b)    PRIORITY IN INCIDENTAL REGISTRATIONS.  If (i) a
registration pursuant to this Section 2.2 involves an underwritten offering
of the securities so being registered, whether or not for sale for the
account of the Company, and (ii) the managing underwriter of such
underwritten offering shall inform the Company and the holders of the
Registrable Securities requesting such registration by letter of its belief
that the number of securities requested to be included in such registration
exceeds the number which can be sold in (or during the time of) such
offering, then (A) in the case of an offering for the account of the Company
or which was demanded by the holders of the Registrable Securities - July
1999 pursuant to the rights of the holders of the Registrable Securities -
July 1999, registration for the Registrable Securities shall be cut back such
that (i) no holder of Registrable Securities shall be entitled to participate
in such underwritten public offering unless all shares of Common Stock
proposed to be sold by the Company for its own account have been included in
such underwritten public offering, and (ii) after the Company has included
its own shares of Common Stock, the holders of Registrable Securities and the
holders of other securities as to which the Company has granted registration
rights including (without limitation) the Registrable Securities - July 1999
("Other Registrable Securities"), including incidental registration rights,
shall be entitled to include their Registrable Securities and Other
Registrable Securities in an amount up to the

                                      -6-
<PAGE>

amount that such managing underwriter or underwriters advise may be included
therein (allocated among the holders of Registrable Securities and the
holders of other Registrable Securities pro rata on the basis of the number
of securities requested to be included therein by each such holder) and (B)
in the case of an offering that was commenced as a result of the exercise of
demand registration rights by Persons other than E-P or other holders of
Registrable Securities, the Persons commencing such registration and the
holders of Registrable Securities shall be entitled to include their
Registrable Securities and Other Registrable Securities in an amount up to
the amount such managing underwriters or underwriters advise may be included
therein (allocated among the persons commencing such registration and the
holders of Registrable Securities pro rata on the basis of the number of
securities requested to be so included therein by each such person or
holder).  If, however, the registration was initiated by the Company within
one hundred twenty (120) days of a requested registration and is in lieu
thereof, then the Company shall include in the registration all Registrable
Securities requested to be included in such registration and shall decrease
the number of securities proposed to be sold by the Company and to be
included in such registration to the extent necessary to reduce the number of
securities to be included in the registration to the level recommended by the
managing underwriter.

       2.3.   REGISTRATION PROCEDURES.  If and whenever the Company is
required to use its best efforts to effect the registration of any
Registrable Securities under the Securities Act as provided in Section 2.1 or
2.2 above, the Company will, as expeditiously as possible:

              (i)    prepare and (as soon thereafter as possible or in any event
       no later than seventy-five (75) days after the end of the period within
       which requests for registration may be given to the Company (ninety (90)
       days in the case of requests for registration made during the last
       quarter of a fiscal year or the first fifteen (15) days of the first
       quarter of any fiscal year) or such longer period as the Company shall in
       good faith require to produce the financial statements required in
       connection with such registration) file with the Commission the requisite
       registration statement to effect such registration and thereafter use its
       best efforts to cause such registration statement to become effective,
       provided that the Company may discontinue any registration of its
       securities which are not Registrable Securities (and, under the
       circumstances specified in Section 2.2(a) above, its securities which are
       Registrable Securities) at any time prior to the effective date of the
       registration statement relating thereto;

              (ii)   prepare and file with the Commission such amendments and
       supplements to such registration statement and the prospectus used in
       connection therewith as may be necessary to keep such registration
       statement effective and to comply with the provisions of the Securities
       Act with respect to the disposition of all securities covered by such
       registration statement until such time as all of such securities have
       been disposed of in accordance with the intended methods of disposition
       by the seller or sellers thereof as set forth in such registration
       statement but in no event for a period which would exceed one hundred
       twenty (120) days from the date on which the registration statement
       became effective;

                                      -7-
<PAGE>

              (iii)  furnish to each seller of Registrable Securities covered by
       such registration statement such number of conformed copies of such
       registration statement and of each amendment and supplement thereto (in
       each case including all exhibits), such number of copies of the
       prospectus contained in such registration statement (including each
       preliminary prospectus and any summary prospectus) and any other
       prospectus filed under Rule 424 under the Securities Act, in conformity
       with the requirements of the Securities Act, and such other documents, as
       such seller may reasonably request;

              (iv)   use its best efforts to register or qualify all Registrable
       Securities and other securities covered by such registration statement
       under such other securities or blue sky laws of such jurisdictions in the
       United States as each seller thereof shall reasonably request, to keep
       such registration or qualification in effect for so long as such
       registration statement remains in effect, and take any other action which
       may be reasonably necessary or advisable to enable such seller to
       consummate the disposition in such jurisdictions of the securities owned
       by such seller, except that the Company shall not for any such purpose be
       required to either qualify generally to do business as a foreign
       corporation, or subject itself to taxation or to general service of
       process in any jurisdiction wherein it would not, but for the
       requirements of this clause (iv), be obligated to be so qualified or
       subject to taxation or service of process, other than as to matters and
       transactions related to such registration or qualification;

              (v)    use its best efforts to cause all Registrable Securities
       covered by such registration statement to be registered with or approved
       by such other United States governmental agencies or authorities as may
       be necessary to enable the seller or sellers thereof to consummate the
       disposition of such Registrable Securities;

              (vi)   furnish to each seller of Registrable Securities a copy of
       each of the following, if any, addressed to the underwriters:

                            (A)    an opinion of counsel for the Company, dated
              the effective date of such registration statement (and, if such
              registration includes an underwritten public offering, dated the
              date of the closing under the underwriting agreement) reasonably
              satisfactory in form and substance to such seller, and

                            (B)    a "comfort" letter, dated the effective date
              of such registration statement (and, if such registration includes
              an underwritten public offering, dated the date of the closing
              under the underwriting agreement), signed by the independent
              public accountants who have certified the Company's financial
              statements included in such registration statement, covering
              substantially the same matters with respect to such registration
              statement (and the prospectus included therein) and, in the case
              of the accountants' letter, with respect to events subsequent to
              the date of such financial statements, as are customarily covered
              in opinions of issuer's counsel and in accountants' letters
              delivered to the underwriters in underwritten public offerings of
              securities and, in the case of the accountants, letter, such other
              financial matters, and, in the case of the legal

                                      -8-
<PAGE>

              opinion, such other legal matters, as such seller (or the
              underwriters, if any) may reasonably request;

              (vii)  (A)    notify each seller of Registrable Securities covered
       by such registration statement, their counsel and the managing
       underwriters, if any, promptly, and (if requested in writing by any such
       Person), confirm such notice in writing:  (1) when a registration
       statement or any amendment thereto has been filed, and, with respect to a
       registration statement or any post-effective amendment, when the same has
       become effective, (2) of any request by the Commission or any other
       Federal or state governmental authority for amendments or supplements to
       a registration statement or related prospectus or for additional
       information, (3) of the issuance by the Commission of any stop order
       suspending the effectiveness of a registration statement or the
       initiation of any proceedings for that purpose, (4) if at any time the
       representations and warranties of the Company contained in any agreement
       (including any underwriting agreement) contemplated by this Section 2
       cease to be true and correct, (5) of the receipt by the Company of any
       notification with respect to the suspension of the qualification or
       exemption from qualification of any of the Registrable Securities for
       sale in any jurisdiction, or the initiation or threatening of any
       proceeding for such purpose, and (6) of the happening of any event that
       makes any statement made in such registration statement or related
       prospectus or any document incorporated or deemed to be incorporated
       therein by reference untrue in any material respect or that requires the
       making of any changes to such registration statement, prospectus or
       documents so that, in the case of the registration statement, it will not
       contain any untrue statement of a material fact or omit to state any
       material fact required to be stated therein or necessary to make the
       statements therein, not misleading, and that in the case of the
       prospectus, it will not contain any untrue statement of a material fact
       or omit to state any material fact necessary in order to make the
       statements therein, in light of the circumstances unde which they were
       made, not misleading, and (B)at the request of any such seller promptly
       prepare and furnish to such seller a reasonable number of copies of a
       supplement to or an amendment of such prospectus as may be necessary (and
       a post-effective amendment to such registration statement as may be
       necessary in connection therewith) so that, as thereafter delivered to
       the purchasers of such securities, such prospectus shall not include an
       untrue statement of a material fact or omit to state a material fact
       required to be stated therein or necessary to make the statements therein
       not misleading in the light of the circumstances under which they were
       made;

              (viii) Use its best efforts to obtain the withdrawal of any order
       suspending the effectiveness of a registration statement, or the lifting
       of any suspension of the qualification (or exemption from qualification)
       of any of the Registrable Securities for sale in any jurisdiction;

              (ix)   If requested by the managing underwriters, if any, or the
       Holders of a majority in interest of the Registrable Securities being
       sold in connection with an underwritten offering, promptly include in a
       prospectus supplement or post-effective amendment such information as the
       managing underwriters, if any, and such Holders may

                                      -9-
<PAGE>

       reasonably request in order to permit the intended method of distribution
       of such securities and make all required filings of such prospectus
       supplement or such post-effective amendment as soon as practicable after
       the Company has received such request;

              (x)    otherwise use its best efforts to comply with all
       applicable rules and regulations of the Commission, and make available to
       its security holders, as soon as reasonably practicable, a historical
       earnings statement covering the period of at least twelve (12) months,
       but not more than eighteen (18) months, beginning with the first month of
       the first full fiscal quarter after the effective date of such
       registration statement, which earnings statement shall satisfy the
       provisions of Section 11 (a) of the Securities Act, and will furnish to
       each such seller at least five business days prior to the filing thereof
       a copy of any amendment or supplement to such registration statement or
       prospectus and shall not file any thereof to which any such seller shall
       have reasonably objected on the grounds that such amendment or supplement
       does not comply in all material respects with the requirements of the
       Securities Act or the rules or regulations thereunder;

              (xi)   provide and cause to be maintained a transfer agent and
       registrar for all Registrable Securities covered by such registration
       statement from and after a date not later than the effective date of such
       registration statement;

              (xii)  use its best efforts to list all Registrable Securities
       covered by such registration statement on any securities exchange or
       trading system on which any of the Common Stock is then listed;

              (xiii) cooperate with the selling holders of Registrable
       Securities and the managing underwriters, if any, to facilitate the
       timely preparation and delivery of certificates representing Registrable
       Securities to be sold, which certificates shall be in a form eligible for
       deposit with The Depository Trust Company; and enable such Registrable
       Securities to be in such denominations and registered in such names as
       the managing underwriters, if any, or holders may request in writing at
       least two (2) business days prior to any sale of Registrable Securities;

              (xiv)  make every reasonable effort to obtain the withdrawal of
       any order suspending the effectiveness of any registration statement at
       the earliest possible moment; and

              (xv)   cooperate and assist in any filings required to be made
       with the NASD and in the performance of any due diligence investigation
       by any underwriter (including any "qualified independent underwriter"
       that is required to be retained in accordance with the rules and
       regulations of the NASD).

       The Company may require each seller of Registrable Securities as to which
any registration is being effected to furnish the Company such information
regarding such seller and

                                      -10-
<PAGE>

the distribution of such securities as the Company may from time to time
reasonably request in writing.

       Each holder of Registrable Securities agrees that, upon receipt of any
notice from the Company of the happening of any event of the kind described
in clause (vii) (A) (3) or (6) of this Section 2.3, such holder will
forthwith discontinue such holder's disposition of Registrable Securities
pursuant to the registration statement relating to such Registrable
Securities until such holder's receipt of the copies of the supplemented or
amended prospectus contemplated by clause (vii) of this Section 2.3 and, if
so directed by the Company, will deliver to the Company (at the Company's
expense) all copies, other than permanent file Copies, then in such holder's
possession of the prospectus relating to such Registrable Securities current
at the time of receipt of such notice.

       2.4.   UNDERWRITTEN OFFERINGS.  (a)  COOPERATION; UNDERWRITING
AGREEMENTS.  If requested by the underwriters for any underwritten offering
by holders of Registrable Securities pursuant to a registration requested
under Section 2.1 above, the Company will enter into an underwriting
agreement with such underwriters for such offering, such agreement to contain
such representations and warranties by the Company and such other terms as
are generally prevailing in agreements of this type, including, without
limitation, indemnities to the effect and to the extent provided in Section
2.6 below.  The holders of the Registrable Securities will reasonably
cooperate with the Company in the negotiation of the underwriting agreement,
provided that nothing herein contained shall diminish the foregoing
obligations of the Company.  The holders of Registrable Securities to be
distributed by such underwriters shall be parties to such underwriting
agreement and any necessary or appropriate custody agreements and execute
appropriate powers of attorney, and may, at their option, require that any or
all of the representations and warranties by, and the other agreements on the
part of, the Company to and for the benefit of such underwriters shall also
be made to and for the benefit of such holders of Registrable Securities and
that any or all of the conditions precedent to the obligations of such
underwriters under such underwriting agreement be conditions precedent to the
obligations of such holders of Registrable Securities.  Any such holder of
Registrable Securities shall not be required to make any representations or
warranties to or agreements with the Company or the underwriters other than
representations, warranties or agreements regarding such holder, such
holder's Registrable Securities and such holder's intended method of
distribution and any other representation required by law.

              (b)    INCIDENTAL UNDERWRITTEN OFFERINGS.  If the Company at
any time proposes to register any of its securities under the Securities Act,
as contemplated by Section 2.2 above, and such securities are to be
distributed by or through one or more underwriters, the Company will, if
requested by any holder of Registrable Securities as provided in said Section
2.2 and subject to the provisions of Section 2.2(b), arrange for such
underwriters to include all the Registrable Securities to be offered and sold
by such holder among the securities to be distributed by such underwriters.
The holders of Registrable Securities to be distributed by such underwriters
shall be parties to the underwriting agreement between the Company and such
underwriters and any necessary or appropriate custody agreements and execute
appropriate powers of attorney, and may, at their option, require that any or
all of the

                                      -11-
<PAGE>

representations and warranties by, and the other agreements on the part of,
the Company to and for the benefit of such underwriters shall also be made to
and for the benefit of such holders of Registrable Securities and that any or
all of the conditions precedent to the obligations of such underwriters under
such underwriting agreement be conditions precedent to the obligations of
such holders of Registrable Securities.  Any such holder of Registrable
Securities shall not be required to make any representations or warranties to
or agreements with the Company or the underwriters other than
representations, warranties or agreements regarding such holder, such
holder's Registrable Securities and such holder's intended method of
distribution and any other representation required by law.

       2.5.   PREPARATION; REASONABLE INVESTIGATION.  In connection with the
preparation and filing of each registration statement under the Securities
Act pursuant to this Agreement, the Company will give the holders of
Registrable Securities registered under such registration statement, the
underwriters, if any, and their respective counsel and accountants, the
opportunity to participate in the preparation of such registration statement,
each prospectus included therein or filed with the Commission, and each
amendment thereof or supplement thereto, and will give each of them such
access to its books and records and such opportunities to discuss the
business of the Company with its officers and the independent public
accountants who have certified its financial statements as shall be
necessary, in the opinion of such holders' and such underwriters' respective
counsel, to conduct a reasonable investigation within the meaning of the
Securities Act.

       2.6.   INDEMNIFICATION.  (a) INDEMNIFICATION BY THE COMPANY.  In the
event of any registration of any securities of the Company under the
Securities Act, the Company will, and hereby does, indemnify and hold
harmless the seller of any Registrable Securities covered by such
registration statement, its directors and officers, each other Person who
participates as an underwriter in the offering or sale of such securities and
each other Person, if any, who controls such seller or any such underwriter
within the meaning of the Securities Act, against any losses, claims, damages
or liabilities, joint or several, to which such seller or any such director
or officer or underwriter or controlling Person may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions or proceedings, whether commenced or threatened, in
respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in any registration
statement under which such securities were registered under the Securities
Act, any preliminary prospectus, final prospectus or summary prospectus
contained therein, or any amendment or supplement thereto, or any omission or
alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and the
Company will reimburse such seller and each such director, officer,
underwriter and controlling Person for any legal or any other expenses
incurred by them in connection with investigating or defending any such loss,
claim, liability, action or proceeding; provided that the Company shall not
be liable in any such case to the extent that any such loss, claim, damage,
liability (or action or proceeding in respect thereof) or expense arises out
of or is based upon an untrue statement or omission made in such registration
statement, any such preliminary prospectus, final prospectus, summary
prospectus, amendment or supplement in reliance upon and inconformity with
written information furnished to the Company through an instrument

                                      -12-
<PAGE>

duly executed by such seller specifically stating that it is for use in the
preparation thereof and, provided further that the Company shall not be
liable to any Person who participates as an underwriter in the offering or
sale of Registrable Securities or any other Person, if any, who controls such
underwriter within the meaning of the Securities Act, in any such case to the
extent that any such loss, claim, damage, liability (or action or proceeding
in respect thereof) or expense arises out of such Person's failure to send or
give a copy of the final prospectus, as the same may be then supplemented or
amended, to the Person asserting an untrue statement or alleged untrue
statement or omission or alleged omission at or prior to the written
confirmation of the sale of Registrable Securities to such Person if such
statement or omission was corrected in such final prospectus.  Such indemnity
shall remain in full force and effect, regardless of any investigation made
by or on behalf of such seller or any such director, officer, underwriter or
controlling Person and shall survive the transfer of such securities by such
seller and the termination or expiration of this Agreement.

              (b)    INDEMNIFICATION BY THE SELLERS.  The Company may
require, as a condition to including any Registrable Securities in any
registration statement filed pursuant to Section 2.3 above, that the Company
shall have received an undertaking reasonably satisfactory to it from the
prospective seller of such securities, to indemnify and hold harmless (in the
same manner and to the same extent as set forth in subparagraph (a) of this
section 2.6) the Company, each director of the Company, each officer of the
Company and each other Person, if any, who controls the Company within the
meaning of the Securities Act, with respect to any statement or alleged
statement in or omission or alleged omission from such registration
statement, any preliminary prospectus, final prospectus or summary prospectus
contained therein, or any amendment or supplement thereto, if such statement
or alleged statement or omission or alleged omission was made in reliance
upon and in conformity with written information furnished to the Company
through an instrument duly executed by such seller specifically stating that
it is for use in the preparation of such registration statement, preliminary
prospectus, final prospectus, summary prospectus, amendment or supplement.
Such indemnity shall remain in full force and effect, regardless of any
investigation made by or on behalf of the Company or any such director,
officer or controlling Person and shall survive the transfer of such
securities by such seller and the termination or expiration of this
Agreement.  The obligations of any seller under this subparagraph (b) shall
be limited to the net proceeds to such seller of the Registrable Securities
sold pursuant to the registration statement to which the loss, claim, damage,
judgment, expense or liability relates.

              (c)    CONTRIBUTION.  If the indemnification provided for in
subparagraphs (a) and (b) above for any reason is held by a court of
competent jurisdiction to be unavailable to an indemnified party in respect
of any losses, claims, damages, judgments, expenses or liabilities referred
to therein, then each indemnifying party under such paragraph, in lieu of
indemnifying such indemnified party thereunder, shall contribute to the
amount paid or payable by such indemnified party as a result of such losses,
claims, damages, judgments, expenses or liabilities in such proportion as is
appropriate to reflect the relative fault, if any, of the Company and the
other selling holders in connection with the statements or omissions which
resulted in such losses, claims, damages, expenses or liabilities, as well as
any other relevant equitable considerations.  The relative fault of the
Company and the selling holders shall be determined by

                                      -13-
<PAGE>

reference to, among other things, whether the untrue statement or alleged
untrue statement of a material fact or the omission or alleged omission to
state a material fact relates to information supplied by the Company or the
selling holders and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company, the holders, and the underwriters agree that it would not be
just and equitable if contribution pursuant to this subparagraph (c) were
determined by pro rata or per capita allocation or by any other method of
allocation which does not take account of the equitable considerations
referred to in the immediately preceding sentence.  The obligations of any
seller under this subparagraph (c) are several, not joint, and shall be
limited to an amount equal to the net proceeds to such seller of Registrable
Securities sold pursuant to the registration statement to which the loss,
claim, damage, judgment expense or liability relates.  No person found guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of
theSecurities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation.

              (d)    NOTICES OF CLAIMS AND PROCEDURES.  Promptly after
receipt by an indemnified Person of notice of the commencement of any action
or proceeding involving a claim referred to in the preceding subparagraphs of
this Section 2.6, such indemnified Person will, if a claim in respect thereof
is to be made against an indemnifying party, give written notice to the
latter of the commencement of such action, provided that the failure of any
indemnified Person to give notice as provided herein shall not relieve the
indemnifying party of his, her or its obligations under the preceding
subparagraphs of this Section 2.6, except to the extent that the indemnifying
party is actually prejudiced by such failure to give notice.  In case any
such action is brought against an indemnified Person, unless in such
indemnified Person's reasonable judgment a conflict of interest between such
indemnified Person and such indemnifying party may exist in respect of such
claim, the indemnifying party shall be entitled to participate in and to
assume the defense thereof, jointly with any other indemnifying party
similarly notified to the extent that it may wish, with counsel reasonably
satisfactory to such indemnified Person, and after notice from the
indemnifying party to such indemnified Person of its election so to assume
the defense thereof, the indemnifying party shall not be liable to such

to be filed by it under the Securities Act and the Exchange Act and the rules
and regulations adopted by the Commission thereunder (or, if the Company is
not required to file such reports, the Company will, upon the request of any
holder of Registrable Securities, make publicly available other information)
and will take such further action as any holder of Registrable Securities may

to time, or (b) any similar rule or regulation hereafter adopted by the

request or other action by any holder or holders of Registrable Securities
pursuant to this Agreement or any determination of any number or percentage
of shares of Registrable Securities held by any holder or holders of
Registrable Securities contemplated by this Agreement.  If the beneficial
