3.   TERM.

     3.1 The Initial Lease Term shall commence on the Commencement Date and
expire at midnight on the Termination Date, unless sooner terminated or extended
as hereinafter provided. When used herein, the term "Commencement Date" is the
earlier of the following:

     (a) date Isonics has obtained equity financing that is, in Isonics'
     discretion, sufficient to carry out the business of manufacturing
     silicon-on-insulator and other silicon wafers as the term "Adequate
     Funding" is used in that certain agreement between Isonics and Lessor dated
     September 14, 2001 which relates to a license between Lessor and Isonics
     and certain other related transactions as described therein; and

     (b) the date Isonics takes possession of and commences use of the leased
     assets.

     3.2 Isonics may, upon fifteen days written notice to Lessor, renew the

     3.3 The Lessor may terminate this lease upon fifteen days written notice to
Isonics if the Commencement Date has not occurred on or before November 30,
2001. If the Lessor sends such written notice to Isonics, Isonics may establish
the Commencement Date during such fifteen day period and, in such case, all
other provisions of this Lease will control.

4.   OBLIGATIONS OF LESSOR.

     4.1 Upon payment by Isonics of the Rent and other Obligations of Isonics as
set forth herein, and upon the observance and performance of all the covenants,
terms, and conditions for which Isonics is responsible, Isonics shall peaceably
and quietly hold and enjoy the Leased Equipment for the entire Term without
hindrance or interruption by Lessor or any other person or persons lawfully or
equitably claiming by, through, or under Lessor's control, nevertheless, to the
terms and conditions of this Lease.

     4.2 During the term of this Lease, Lessor shall not voluntarily,
involuntarily, directly, indirectly, or by operation of law assign, transfer, or
encumber the Leased Equipment or any portion thereof or any interest therein
without the prior written consent of Isonics.

                                       2
<Page>

5.   OBLIGATIONS OF ISONICS. During the Lease Term, Isonics shall pay Rent and
all Operating Costs (as hereinafter defined) on or before the date first due.

     5.1 RENT. Isonics shall pay Rent (including any Additional Rent) on a
monthly basis, on or before the first day of each month during the Lease Term.
Monthly Rent shall be as set forth above. Rent shall be delinquent, and this
Lease shall be in default if Lessor has not received the Rent payment by the
tenth day of the month for which the Rent is due. At Isonics's or Lessor's
request, Isonics will make payments to Lessor by wire transfer of funds to an
account designated by Lessor.

     (a) As Additional Rent, Isonics will pay when due all Personal Property
     Taxes. As used in this Lease, the term "Personal Property Taxes" shall mean
     any and all taxes, charges and assessments (special or general, ordinary or
     extraordinary) levied with respect to the Leased Equipment.

     (b) As Additional Rent, Isonics will be responsible for all operating and
     maintenance expenses for the Leased Equipment.

     5.2 DEDUCTIONS FROM RENT. Isonics is entitled to reduce the Rent to the
extent any of the Leased Equipment becomes unavailable to Isonics through no
fault of Isonics, whether such action results from a vendor or financer of the
Leased Equipment taking possession of the Leased Equipment (or any portion
thereof) because of a failure by the Lessor to make necessary payments or
because the Leased Equipment (or any portion thereof) fails due to normal wear
and tear. The amount of the deduction shall be as described on Exhibit "A," or
if no specific deduction is reflected on Exhibit "A," an amount equal to the
fair lease value of the equipment that failed.

     5.3 RENT DEFERRAL. If Isonics commences this Lease before receiving
Adequate Funding, then Isonics may defer payment of Rent for the first three
months of this Lease. In that event, Isonics will pay Rent at the rate of
$40,000 per month for the remaining nine months of the initial term of this
Lease.

6.   Not included.

7.   NO LIENS. Isonics shall keep the Leased Equipment clear from any and all
liens arising out of any work performed, materials furnished or obligations
incurred by or for Isonics.

8.   SECURITY. Isonics, at its own expense, shall provide adequate security for
the Leased Equipment.

                                       3

9.   THE LEASED EQUIPMENT. Isonics acknowledges that the Leased Equipment is
located in premises that are leased by third parties to Lessor, although Lessor
is in default in certain of its obligations under leases to those third parties.
Lessor represents that it has had conversations about these defaults and based
on those discussions believes that Isonics will be able to negotiate alternative
arrangements with the third parties. Isonics agrees to use its best efforts to
negotiate accommodation with these third parties, but to the extent Isonics must
pay the third parties (or provide other value to the third parties) in excess of
the amount set forth in the leases for such premises on a going-forward basis
from the Commencement Date, Isonics may pay such expenses and add the amount so
paid to the amounts advanced by Isonics to the Lessor under a loan and security
agreement entered into between the parties.

10.  COVENANTS AND WARRANTIES. Isonics and Lessor agree and warrant as follows:

     10.1 At the Commencement Date, the Lessor warrants to Isonics that the
Leased Equipment is in good repair and operable physical condition, given the
age of the and prior use of the Leased Equipment. At the Commencement Date, the
Lessor is not aware of any material maintenance or repairs that need to be made
to the Leased Equipment in order to make any portion of the Leased Equipment
usable or operational.

     10.2 Isonics will operate the Leased Equipment in accordance with the
operating instructions for the Leased Equipment and in accordance with the
historical practice pursuant to which the Lessor previously operated the Leased
Equipment.

     10.3 Upon the termination of this Lease for any reason, Isonics will return
the Leased Equipment to the Lessor.

11.  INSURANCE. Isonics shall, during the entire term hereof, keep in full force
and effect a policy of general liability and property damage insurance with
respect to the Leased Equipment, and the business operated by Isonics, in which
the limits of liability per occurrence and in which the limit of property damage
liability shall not be less than reasonably required for the nature of the
business being conducted.

12.  DAMAGE OR DESTRUCTION. In case of damage to or destruction of the Leased
Equipment by fire, vandalism, malicious mischief or any other casualty, Isonics
shall be entitled to all proceeds from any insurance policies.

13.  INDEMNIFICATION. Isonics covenants and agrees to protect and save Lessor
harmless and indemnified against and from any penalty or damage or charges
imposed for any violation of any laws or ordinances, either occasioned by
Isonics in connection with its usage of the Leased Equipment. Isonics further
agrees to protect, indemnify and save Lessor harmless from and against any and
all claims, and against any and all loss, cost, damage or expense, including

                                       4
<Page>

without limitation, reasonable attorneys' fees, arising out of any failure of
Isonics in any respect to comply with and perform all the requirements and
provisions hereof.

13.  IMPROVEMENTS AND ALTERATIONS. Isonics has the right to make and Lessor
consents to Isonics making all alterations, installations, additions, and
improvements ("Improvements") necessary for the operation or maintenance of the
Leased Equipment. Improvements by Isonics shall be made at Isonics's sole cost
and expense.

14.  DEFAULT BY ISONICS AND RIGHTS OF LESSOR.

     14.1 DEFAULTS. If Isonics fails to perform any covenant, term, agreement or
condition of this Lease within 30 days after notice from Lessor (provided,
however, that if the nature of such default other than for nonpayment is such
that the same cannot reasonably be cured within such 30-day period, Isonics
shall not be deemed in default if Isonics shall commence such cure within said
30-day period and thereafter diligently prosecutes the same to completion), then
Lessor, in addition to all other rights and remedies available to Lessor by law
or by other provisions hereof, may, without process, immediately remove all
persons and property, and, at Lessor's option, terminate this Lease as to all
future rights of Isonics.

     14.2 REMEDIES

          (a)  Isonics hereby agrees to pay Lessor and to indemnify Lessor for
all reasonable attorneys' fees and expenses incurred in enforcing any of the
terms of this Lease or any other rights or remedies of Lessor.

          (b)  To the extent that Isonics fails to pay any amount due hereunder
on or before the date such payment was due (including Rent), such amount will be
considered to be additional Rent (unless the default relates to the payment of
Rent) and Isonics will be obligated to pay Lessor, at Lessor's discretion, an
amount equal to 5% or less of such Rent or additional Rent on demand by Lessor.
The additional amounts required by this Paragraph shall also be considered
additional Rent and shall be added to and included within Rent as such are
incurred.

15.  OPTION TO PURCHASE: By executing this Lease, Lessor grants Isonics the
right to purchase the Leased Equipment, or any portion thereof, at any time
during this Agreement for a price equal to the "orderly liquidation value" as
determined by a third party appraiser acceptable to both Lessor and Lessee. If
the Lessee exercises this option during the first twelve months of this lease,
the remaining lease payments due during the first twelve months of this lease
will be added to the "orderly liquidation value."

16.  MISCELLANEOUS PROVISIONS.

providing a method whereby the Rent is to be measured and ascertained.

     16.4 NON-WAIVER. Waiver by Lessor or Isonics of any breach of any term,

Isonics's knowledge of such preceding breach at the time of acceptance or
payment of Rent.

     16.5 ENTIRE AGREEMENT. Except as otherwise set forth in this Lease, this

indicate, the obligations of Lessor and Isonics pursuant to such section of this
Lease shall survive the termination of this Lease.

of a lesser amount than Rent, and other charges stipulated herein shall be
deemed to be other than on account of the earliest stipulated Rent or other

accompanying any check or payment as Rent be deemed an accord and satisfaction,

right to recover the balance of such Rent, and other charges or pursue any other
remedy in this Lease.
