                                    -------------------------

                                    (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



                                     - 6 -
<PAGE>   18


                           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).

                                    (B) If the Supplier partially performs under
                           the Supply Contract but such partial performance
                           constitutes a Supplier NonPerformance, 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
                           NonPerformance, 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






                                     - 7 -
<PAGE>   19

                           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.

                  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



                                     - 8 -
<PAGE>   20

                  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 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


                                     - 9 -
<PAGE>   21


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. 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.

         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)

         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




                                     - 10 -
<PAGE>   22



         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.

                  6.3(o).  commit to any of the foregoing.

         6.4 CONSENTS. ISONICS shall use its best efforts to:

         make all filings with and give all notices that may be necessary or

         obligations of E-P to be satisfied.

         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



                                    - 14 -
<PAGE>   26

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.


                                      VII.
                         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



                                    - 15 -

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 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



                                    - 16 -
<PAGE>   28

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.


                                      VIII.

         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

         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

<PAGE>   29

         Liabilities or (iv) any liability of ISONICS under Environmental Laws
         incurred prior to the Closing Date.

         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.

                  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 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.

warranties that by their terms speak only as of a specified date, each of the

                  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 or otherwise prohibited or if completion of the Contemplated

         judgment of any court or Governmental Authority having competent
         jurisdiction;

                  12.1(c). by either E-P or ISONICS if the Closing shall not
         have been completed by December 31, 1999; provided, however, that
         neither E-P nor ISONICS may terminate 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.

         12.2 EFFECT OF TERMINATION. If this Agreement is terminated as
permitted 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

                    REPRESENTATIONS AND WARRANTIES OF ISONICS


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

         1. ORGANIZATION, GOOD STANDING AND CAPITALIZATION.

                  1.1 ISONICS (i) is a corporation duly organized, validly

         to enter into this Agreement and perform its obligations hereunder and
         (iii) and is duly qualified and in good standing as a foreign
         corporation authorized to do business in every jurisdiction where the
         failure so to qualify, individually or in the aggregate, would have a
         Material Adverse Effect.

                  1.2 The authorized capital of ISONICS consists of 20,000,000
         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 value, of which 1,830,000 shares are outstanding. All
         outstanding shares were, and the Warrant Shares when issued will be,
         issued in compliance with all applicable Federal and State securities
         laws. Except as set forth in the ISONICS 1934 Act Reports or on
         SCHEDULE B1.2, there are (i) no outstanding subscriptions, warrants,
         options, conversion privileges or other rights or agreements to

         ISONICS (or shares reserved for such purpose), (ii) no preemptive
         rights or rights of first refusal with respect to the issuance of
         additional shares of capital stock of ISONICS, including the Warrant
         Shares and (iii) no commitments or understandings (oral or written) of
         the Company to issue any shares, warrants, options or other rights. To
         the best of ISONICS knowledge, except as set forth in the ISONICS 1934
         Act Reports or on SCHEDULE B1.2, none of the shares of Common Stock are
         subject to any shareholders' agreement, voting trust agreement or
         similar arrangement or understanding. Except as set forth in the
         ISONICS 1934 Act Reports or on SCHEDULE B1.2, the Company has no
         outstanding bonds, debentures, notes or other obligations the holders
         of which have the right to vote (or which are convertible into or
         exercisable for securities having the right to vote) with the
         stockholders of ISONICS on any matter.

                  1.3 The issuance of the Warrant Shares has been duly
         authorized and the Warrant Shares have been, and at all times prior to
         exercise will have been, duly reserved for issuance and, when so
         issued, will be validly issued, fully paid and non-assessable.

         Coast Business Credit which includes substantially all of ISONICS"
         assets as collateral will be repaid at the Closing from the proceeds to
         be paid to ISONICS from the Contemplated Transactions), or (v) cause

         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.

                  3.2 FINANCIAL STATEMENTS. Each of the consolidated balance
         sheets 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



<PAGE>   47


         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. SUBSIDIARIES.

                  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


<PAGE>   49


         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


<PAGE>   50


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 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.

         12. ENVIRONMENTAL MATTERS. Except as set forth on SCHEDULE B12 or in
the ISONICS 1934 Act Reports, to the knowledge of ISONICS:

                  12.1 The facilities occupied or used by ISONICS or any Company
         Subsidiary and any real property presently or formerly owned by, used
         by or leased to or by ISONICS or any Company Subsidiary or any
         predecessor of ISONICS or any Company Subsidiary (collectively, the
         "Property"), the existing and prior uses of such Property and all
         operations of the businesses of ISONICS and each Company Subsidiary
         comply and have at all times complied in all material respects with all
         Environmental Laws, and ISONICS and each Company Subsidiary is not in
         violation of nor has it violated, in connection with the ownership,
         use, maintenance or operation of such Property or the conduct of its
         business, any Environmental Law.

                  12.2 ISONICS and each Company Subsidiary have all permits,
         registrations, approvals and licenses required by any Governmental
         Authority or Environmental Law.

                  12.3 There has been no spill, discharge, leak, emission,
         injection, 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 Property. No asbestos-containing materials,
         underground storage tanks or polychlorinated biphenyls ("PCBs") are
         located on such Property.

                  13.2 There are no claims, notices of violations, notice
         letters, investigations, inquiries or other proceedings now pending or
         threatened by any Governmental Authority or third party with respect to
         the DZ Business, the other businesses of



<PAGE>   51


         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.

         14. ZINC ASSETS. ISONICS has good and marketable title to the Zinc
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 constitute all
operating assets owned by ISONICS or any of its Subsidiaries which are necessary
to conduct the DZ Business in the manner previously conducted by ISONICS.

         15. TAX RETURNS AND TAXES.

                  15.1 All Tax Returns required to be filed by or on behalf of
         ISONICS or any Company Subsidiary have been duly filed and such Tax
         Returns are complete and accurate in all material respects. All Taxes
         with respect to ISONICS and each Company Subsidiary or its assets shown
         to be payable on the Returns or on subsequent assessments with respect
         thereto have been paid in full, and no other Taxes are payable by
         ISONICS with respect to ISONICS or its assets. There are no liens on
         any of ISONICS" assets with respect to Taxes, other than liens for
         Taxes not yet due and payable. For the purposes of the foregoing:

                  (a) "Returns" means all reports, estimates, declarations of
         estimated tax, information statements and returns relating to, or
         required to be filed in connection with, any Taxes, including

for extensions of time in respect of the assessment or collection of any unpaid

relationship with ISONICS or any Company Subsidiary or, following Closing, E-P
in respect of the DZ Business.

         18. YEAR 2000. All of the computer software programs, databases and
compilations, computer hardware (whether general or special purpose), and other
similar or related items of


<PAGE>   54

malfunction, will not cease to function, will not generate incorrect data, and
will not provide incorrect results when processing, providing, or receiving
date-related data into and between the twentieth and twenty-first centuries,
except for such problems which collectively would not have a Material Adverse
Effect.

         19. NO DISCRIMINATION. Neither ISONICS (or any Company Subsidiary) nor
any Employee of ISONICS (or any Company Subsidiary) has (i) committed any unfair
labor practice, (ii) discriminated against any Employee or any other Person
whether or not an Employee, based on that Employee's or Person's age, race,
creed, color, sex, religion, handicap or disability, or (iii) received any
complaints or notices from any Employee, other Person, or any Governmental
Authority alleging any such act.

         20. EMPLOYMENT OBLIGATIONS. Except as described in the ISONICS 1934 Act
Reports, neither ISONICS nor any of the Company Subsidiaries has any material
obligations, contingent or otherwise, under any employment, severance or
consulting agreement.

         21. CONTRACTS. Except as set forth in the ISONICS 1934 Act Reports or
SCHEDULE B21, neither ISONICS nor any Company Subsidiary is a party or is
subject to, and their property and assets are not bound or affected by, any
contract which is material to the business or financial condition of ISONICS,
the DZ Business or the DZ Assets (a "Company Material Contract"). Except as set
forth in SCHEDULE B21, all Company Material Contracts are or will be valid and
binding and are or will be in full force and effect and enforceable in
accordance with their respective terms. Except as set forth in SCHEDULE B21, no
consent of any person is needed in order that each such Company Material
Contract shall continue in full force and effect in accordance with its terms
without penalty, acceleration or rights of early termination by reason of the
consummation of the transactions contemplated by this Agreement, except for
consents the absence of which, individually or in the aggregate, would not
reasonably be expected to have a Material Adverse Effect. Neither ISONICS nor
any Company Subsidiary is in violation or breach of or default under any such
Company Material Contract, nor to ISONICS' knowledge is any other party to any
such Company Material Contract in violation or breach of or default under any
such Company Material Contract, in each case where such violation or breach
would give rise to a right of termination or modification. For purposes of this
Agreement "Government Bid" shall mean any quotation, bid or proposal submitted
to any Governmental Body or any proposed prime contractor or higher-tier
subcontractor of any Governmental Body. For purposes of this Agreement
"Government Contract" shall mean any prime contract, subcontract, letter
contract, purchase order or delivery order executed or submitted to or on behalf
of any Governmental Body or any prime contractor or higher-tier subcontractor,

subcontractor otherwise has or may acquire any right or interest.

         22. FULL DISCLOSURE. The representations and warranties made herein by
ISONICS 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
                         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


<PAGE>   56


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,


<PAGE>   57


         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,


<PAGE>   58


the capacity to protect its interest in connection with the acquisition of the
Warrant. E-P has the 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.

Eagle-Picher Technologies, LLC                       to acquire 4,000,000 shares


                  This Warrant and any shares acquired upon the exercise of this
         Warrant have not been registered under the Securities Act of 1933. This
         Warrant and such shares may not be sold or transferred in the absence
         of such registration or an exemption therefrom under said Act which
         exemption must be established to the reasonable satisfaction of the
         Company. This Warrant and such shares may not be transferred except
         upon the conditions specified in this Warrant, and no transfer of this
         Warrant or such shares shall be valid or effective unless and until
         such conditions shall have been complied with.


                               ISONICS CORPORATION

                          COMMON STOCK PURCHASE WARRANT

subject to the terms set forth below, to purchase from the Company at any time

         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 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



                                      - 2 -
<PAGE>   61


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 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



                                     - 3 -
<PAGE>   62


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 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


                                     - 4 -
<PAGE>   63



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 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



                                     - 5 -
<PAGE>   64


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 kilograms) 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,

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


                                     - 6 -
<PAGE>   65


                  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)
may direct, calling in the aggregate on the face or faces thereof for the 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



                                     - 7 -
<PAGE>   66


cancellation of such Warrant, the Company at is expense will execute and

         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 Denver,
Colorado, for the purpose of issuing Common Stock (or Other Securities) upon the
exercise of the Warrants pursuant to Section 2, exchange of Warrants pursuant to
Section 12, and replacement of Warrants pursuant to Section 13, or any of the
foregoing, and thereafter any such issuance, exchange or replacement, as the
case may be, shall be made at such office by such agent.

         15. REMEDIES. The Company stipulates that the remedies at law of the
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

                  (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



                                     - 8 -
<PAGE>   67


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 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



                                     - 9 -
<PAGE>   68


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
