         THIS SUBLEASE AGREEMENT ("Sublease") is entered as of the Effective

                                      -2-






         THE PARTIES ENTER this Sublease on the basis of the following facts,
understandings and intentions:

         A. Gamma Precision Technology, Inc., a California corporation ("GPT"),
entered into that certain Lease dated June 22, 2000 (the "Master Lease") with
ProLogis Limited Partnership - I, a Delaware limited partnership, for the lease
of approximately 17,350 RSF of the Building. A copy of the Master Lease
(including all exhibits thereto) is attached as EXHIBIT C hereto and made a part
hereof.

         B. Pursuant to an agreement of merger and plan of reorganization dated
as of August 30, 2000, Gasonics International Corporation, a Delaware
corporation ("Gasonics"), acquired all of the outstanding common shares of GPT
and the Master Lease was assigned to Gasonics with the landlord's consent dated
September 18, 2002.

         C. Pursuant to a merger and acquisition between Gasonics and Sublessor,
Sublessor acquired all of the shares of Gasonics and became the
successor-in-interest to Tenant's interest in the Master Lease under an
assignment and assumption of lease between Gasonics and Sublessor dated January
10, 2001.

         D. Sublessor desires to sublease the Premises to Sublessee, and
Sublessee desires to sublease the Premises from Sublessor, on all of the terms,
covenants and conditions hereinafter set forth.

         NOW, THEREFORE, IN CONSIDERATION of the mutual covenants and promises
of the parties, the parties hereto agree as follows:

         1. SUBLEASE. Sublessor shall sublease to Sublessee, and Sublessee shall
sublease from Sublessor, the Premises for the Term upon all of the terms,
covenants and conditions herein contained, and Sublessee shall have the right to
use all common areas within the Project (as that term is defined in the Master
Lease) to the extent that Sublessor has such rights under the Master Lease.
Sublessor warrants and represents to Sublessee that (i) Sublessor has not
executed any amendments or modifications to the Master Lease and that the
documents attached hereto as Exhibit C, as assigned, constitute a full and
complete copy of the Master Lease, (ii) the Master Lease commenced on June 22,
2000 and, unless sooner terminated in accordance with the terms of the Master
Lease, the term expires on July 31, 2003, (iii) as of the date of execution
hereof by Sublessor, Sublessor has received no written notice from Landlord of
any current default or breach of any of the terms of the Master Lease, nor to
its knowledge is there any fact or circumstance that with the delivery of notice
or the passage of time would constitute an event of default under the Master
Lease, and (iv) Sublessor is in possession of the Premises.

         2. CONDITION OF THE PREMISES.

                  a. PHYSICAL CONDITION. Sublessee acknowledges that Sublessee
has conducted Sublessee's own investigation of the Premises and the physical
condition thereof, including accessibility and location of utilities,
improvements, existence of hazardous materials, including but not limited to
asbestos, asbestos containing materials, polychlorinated biphenyls (PCB), and
earthquake preparedness, which in Sublessee's judgment affect or influence
Sublessee's use of the Premises and Sublessee's willingness to enter into this
Sublease. Sublessee shall, except for the representations expressly set forth in
this subparagraph, rely solely on Sublessee's own inspection and examination of

                                      -3-






such items and not on any representations of Sublessor, express or implied.
Sublessee agrees that the Premises shall be subleased on an "as is" built-out
condition with the exception of the improvements shown on Exhibit B, which
improvements are estimated to be completed by Sublessor on or before October 23,
2002, and that Sublessor has made no representations or warranties of any kind
in connection with improvements or physical conditions on, or bearing on, the
use of the Premises, except as expressly set forth in this subsection and
Section 9.

                  b. REPRESENTATION AND WARRANTY. Sublessee represents and
warrants to Sublessor that Sublessee has been given the opportunity to examine
and inspect all matters with respect to taxes, expenses, insurance costs, bonds,
permissible uses, the Master Lease, zoning, covenants, conditions and
restrictions and all other matters which, in Sublessee's judgment, bear upon the
value and suitability of the Premises for Sublessee's purposes, and that
Sublessee has either so examined or investigated such matters or knowingly
declined to so examine or investigate any or all of such matters. Except as
otherwise expressly provided herein, Sublessee has and will rely solely on
Sublessee's own inspection and examination of such items and not on any
representations of Sublessor. Based thereon, Sublessee agrees to accept delivery
of the Premises in their condition as of the date this Sublease is fully
executed, subject only to Sublessor's obligation to complete the Tenant
Improvements described in EXHIBIT B.

         3. SUBLEASE SUBJECT TO MASTER LEASE.

                  a. INCLUSIONS. All of the terms., conditions and covenants of
this Sublease shall be those stated herein and those stated in the Master Lease,
the terms of which are incorporated herein by reference, except as excluded in
Section 3.b herein, modified as appropriate in the circumstances so as to make
such terms, covenants and conditions applicable only to the subleasing
hereunder. Sublessee shall be subject to, bound by, to the extent applicable to
Sublessee's use of the Premises, assume, and comply with all of said terms,
covenants and conditions of the Master Lease with respect to the Premises and
shall satisfy all applicable terms and conditions of the Master Lease for the
benefit of both Master Lessor and Sublessor, it being understood and agreed that
wherever in the Master Lease the word "Tenant" appears, for the purposes of this
Sublease, the word "Sublessee" shall be substituted; where the word "Landlord"
appears, for the purposes of this Sublease, the word "Sublessor" shall be
substituted; where the word "Term" appears, for the purposes of this Sublease,
such word shall have the definition set forth in Part I hereof; and wherever the
word "Premises" for purposes of this Sublease, such word shall refer only to the
extent of the Premises sublet under this Sublease; and that upon the breach
beyond any applicable cure period of any of said terms, conditions or covenants
of the Master Lease by Sublessee or upon the failure of Sublessee to pay Monthly
Rent or any other amount comprising Rent or to comply with any of the provisions
of this Sublease, Sublessor may exercise any and all applicable rights and
remedies granted to Master Lessor by the Master Lease. In the event of any
conflict between this Sublease and the Master Lease, the terms of this Sublease
shall control. Sublessor shall use its good faith best efforts to maintain the
Master Lease in full force and effect during the term of this Sublease;
provided, however, that Sublessor shall not be liable to Sublessee for any
default or failure by Master Lessor, or any earlier termination of the Master
Lease that is not due to the fault of the Sublessor. Whenever the provisions of

                                      -4-






the Master Lease incorporated as provisions of this Sublease require the written
consent of Master Lessor, said provisions shall be construed to require the
written consent of both Master Lessor and Sublessor; provided, that Sublessor
shall have ten (10) business days from the date of Sublessor's receipt of
Sublessee's request to respond in writing to such request and if Sublessor fails
to do so within said ten (10) business day period, Sublessor shall be deemed to
have approved of Sublessee's request. Sublessee hereby acknowledges that it has
read and is familiar with all the terms of the Master Lease, and agrees that
this Sublease is subordinate and subject to the Master Lease and that any
termination thereof may likewise terminate this Sublease and any obligation
whatsoever of Master Lessor to provide the Premises to Sublessee. Upon the
expiration of the term of the Master Lease, the Term of the Sublease shall also
expire and Sublessee shall no longer have the right to possession of the
Premises. Sublessor agrees to maintain the Master Lease in force during the
entire term of this Sublease not to enter into any amendment to the Master Lease
that will diminish Sublessee's rights or increase its obligations under this
Sublease, and to pay rent to Master Lessor in accordance with the terms of the
Master Lease, subject however, to any early termination of the Master Lease as
expressly provided therein without the default of Sublessor. Sublessee shall
comply with the Master Lease, all applicable laws, and any other covenants,
conditions and restrictions affecting the Building.

                  b. EXCLUSIONS. The terms and provisions of the following
Paragraphs and portions of the Master Lease are not incorporated into this
Sublease: Section 4 as it pertains to the amount of Base Rent; Section 5 as it
pertains to the amount of the Security Deposit and Section 6 as it pertains to
the amount of Operating Expenses.

                  c. TIME FOR NOTICE. The time limits provided for in the
provisions of the Master Lease for the giving of notice, making of demands,
performance of any act, condition or covenant, or the exercise of any right,
remedy or option, are amended for the purposes of this Sublease by lengthening
or shortening the same in each instance by three (3) business days, as
appropriate, so that notices may be given, demands made, or any act, condition
or covenant performed, or any right, remedy or option hereunder exercised, by
Sublessor or Sublessee, as the case may be within the time limit relating
thereto contained in the Master Lease. If the Master Lease allows only five (5)
days or less for Sublessor to perform any act, or to undertake to perform such
act, or to correct any failure relating to the Premises or this Sublease, then
Sublessee shall nevertheless be allowed five (5) days to perform such act,
undertake such act and/or correct such failure. Provided, however, that if
Sublessee has commenced to cure a nonmonetary default within any cure or notice
periods that the Master Lease allows and is diligently pursuing such cure,
Sublessee shall be provided with such additional time as is reasonably necessary
to complete such cure if, due to the nature of the breach, the cure cannot be
completed within the express time period granted herein and Master Lessor agrees
to such additional time.

         4. MASTER LESSOR'S OBLIGATIONS. It shall be the obligation of Master
Lessor to (i) provide all services to be provided by Master Lessor to Sublessor
under the terms of the Master Lease and (ii) to satisfy all obligations and
covenants of Master Lessor made to Sublessor in the Master Lease. Sublessee
acknowledges that Sublessor shall be under no obligation to provide such
services or satisfy any such obligations or covenants (including, without
limitation, to make any repairs or replacements to the Premises); provided,
however, Sublessor, upon written notice by Sublessee, shall diligently attempt
to enforce all obligations of Master Lessor under the Master Lease for the
benefit of Sublessee.

                                      -5-

                  a. MONTHLY RENT. Sublessee shall pay to Sublessor as Monthly
Rent as set forth in the Basic Sublease Information, hereinabove, and other
monetary obligations of Sublessee to Sublessor under the terms of this Sublease,
in advance on the first day of each month of the Term, commencing on the Rent
Commencement Date. In the event the Rent Commencement Date is not the first day
of a calendar month or the last day of a rent period or the last day of the Term
is not the last day of the calendar month, the Monthly Rent shall be
appropriately prorated based on the actual number of days in the partial month.
All installments of Monthly Rent shall be paid in lawful money of the United
States and without deduction or offset for any cause whatsoever, but subject to
any abatement of rent granted under the Master Lease to Sublessor to the extent
applicable to the Premises. On the Effective Date, Sublessee shall pay to
Sublessor one installment of Monthly Rent to be applied by Sublessor to the
payment of Monthly Rent for the first month's rent due hereunder.

                  b. ADDITIONAL RENT. Sublessee's Proportionate Share of
Sublessor's Proportionate Share as set forth in the Basic Sublease Information,
hereinabove, and the rent for the Storage Space described in Section 15 below
shall be considered "Additional Rent." Additional Rent shall also include
expenses or charges applicable to the Premises, which may be imposed, at any
time, on Sublessor pursuant to the Master Lease (expressly excluding any late
charges, interest or damages or other charges or penalties imposed on Sublessor
due to its negligence, willful misconduct, default or delay beyond any
applicable grace period pursuant to the terms of the Master Lease) as described

hazardous or toxic materials, in, on, under, from or about the Premises caused
by Sublessee, its agents, employees or contractors, unless such Claims arise out
