                                    --------

Subtenant in accordance with that certain sublease (the "Sublease") dated August

                                   ---------

     NOW, THEREFORE, in consideration of the foregoing and the covenants,
promises and undertakings set forth herein, and for other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the
parties hereto agree as follows:

     1. Landlord's Consent. Landlord hereby consents to the Sublease in the form
        ------------------
attached hereto as Exhibit A. The Sublease shall not be amended or modified
without the prior written consent of Landlord. This consent is granted only upon
the terms and conditions of this Agreement, and Tenant and Subtenant hereby
agree to each of such terms and conditions.

     2. Master Lease.
        ------------

        2.1 The Sublease shall be subject and subordinate at all times to the
Master Lease and to all of its provisions, covenants and conditions. Landlord
shall not be bound or estopped in any way by any of the terms, covenants, or
conditions of the Sublease, nor shall any provision of the Sublease or this
Agreement operate as an express or implied consent to or approval or
ratification by Landlord of any specific provisions of the Sublease or as an
endorsement, representation or warranty of any kind by Landlord regarding the
Premises, Tenant, the Master Lease or any other matter, all of which are
expressly disclaimed. In case of any conflict between the provisions of the
Master Lease and the provisions of the Sublease, as


<PAGE>



between Landlord and Tenant, the provisions of the Master Lease shall
prevail unaffected by the Sublease. Tenant and Subtenant agree that the Sublease
is hereby amended to conform to the terms and conditions of this Agreement.
Without limiting the generality of the foregoing, the Sublease is hereby amended
as follows:

               (a) Section 6.1 of the Sublease is hereby deleted in its entirety
and replaced with the following:

               "6.1 Use. The Premises shall be used and occupied only
          for office, administration, research and development, system
          assembly, light manufacturing, storage, and distribution and
          for no other purpose."

               (b) Sections 8.1, 8.2, and 9.5 of the Sublease are hereby deleted
in their entirety.

               (c) Section 9.6 of the Sublease is hereby deleted in its entirety
and replaced with the following:

               "9.6 Sublessee shall have the right to cure any default
          of Sublessor described in any notice of default within ten
          (10) days after service of such notice of default on
          Sublessee. If such default is cured by Sublessee then
          Sublessee shall have the right of reimbursement and offset
          from and against Sublessor."

          2.2    Nothing contained in the Sublease shall alter, amend, expand or
reduce any of the obligations of Landlord or Tenant under the Master Lease, nor
impose on Landlord any obligation to provide notice to, or obtain consent from,
Subtenant with respect to amendments, defaults, waivers or any other matters
pertaining to the Master Lease or the Premises. Except to the extent the
Sublease becomes a direct lease between Landlord and Subtenant pursuant to
Section 4.1 below, all communications with Landlord regarding the Master Lease,
the Premises, the Sublease or Subtenant shall be recognized by Landlord only if
made by Tenant, not Subtenant, including without limitation, requests for
approvals as required under the Master Lease and requests for any service to be
supplied by Landlord to the Subleased Premises. Tenant consents that Landlord
may elect to communicate directly with Subtenant regarding Subtenant's occupancy
of the Subleased Premises or the Sublease without any implied waiver of this
provision. Tenant shall indemnify, protect, defend and hold Landlord harmless
from any liability of, or claim against Landlord by Subtenant which arises from
Tenant's failure to timely provide notice to Landlord of requests made by
Subtenant to Tenant, as the sublandlord under the Sublease.

     3.   Relationship with Landlord.
          --------------------------

          3.1   Except as otherwise provided by law, nothing contained in this
Agreement or the Sublease shall be deemed to create privity of contract between
Landlord and Subtenant, to make Subtenant a third party beneficiary of the
provisions of the Master Lease, or to create or permit any direct right of
action by Subtenant against Landlord for breach of the covenant of quiet
enjoyment or any other covenant of Landlord under the Master Lease. Landlord
shall have no obligations nor incur any liability to Subtenant with respect to
any warranties of any nature, whether pursuant to the Master Lease or the
Sublease, or otherwise, including, without

<PAGE>



limitation, any warranties respecting use, compliance with zoning,
construction, or fitness of the Subleased Premises for Subtenant's purposes.

          3.2 Tenant hereby irrevocably authorizes and directs Subtenant, upon
receipt of any written notice from Landlord stating that a default exists in the
performance of Tenant's obligations under the Master Lease, to pay to Landlord
the rents and other amounts due and to become due under the Sublease as such
rents and other amounts shall become due and payable under the Sublease. Tenant
agrees that Subtenant shall have the right to rely upon any such statement and
request from Landlord, and that Subtenant shall pay such rents and other amounts
to Landlord without any obligation or right to inquire as to whether such
default exists and notwithstanding any notice from or claim from Tenant to the
contrary, and Tenant shall have no right or claim hereunder against Subtenant
for any such rents or other amounts so paid by Subtenant. Such payments to
Landlord shall satisfy and discharge Subtenant's obligation for the payment of
rent and other amounts under the Sublease to the full extent of such payments
made to Landlord.

     4.   Termination of Master Lease.
          ---------------------------

          4.1  Any termination of the Master Lease for any reason shall
constitute, without further act or deed, a termination of the Sublease, provided
that Landlord shall have the option, at its sole election, to:

               (a) elect by written notice to continue the Sublease solely with
respect to the Subleased Premises without any additional or further agreement of
any kind on the part of Subtenant and with the same force and effect as if
Landlord, as landlord, and Subtenant, as tenant, had entered into a lease as of
the effective date of such expiration, termination or surrender of the Master
Lease for a term equal to the then unexpired term of the Sublease, and
containing the same terms and conditions as those contained in the Sublease
(except as specifically provided in this Agreement), in which event Landlord
shall assume Tenant's obligations as sublandlord thereunder and Subtenant shall
attorn to Landlord as landlord on such terms and conditions.

               (b) enter into a lease directly with Subtenant for the balance of
the term remaining under the Sublease, for the same consideration and upon the
same terms and conditions as in the Sublease. If Landlord exercises such option,
Landlord and Subtenant shall enter into a new lease directly between Landlord
and Subtenant upon such terms and conditions.

          4.2  If Landlord elects to proceed under either Sections 4.1(a) or
4.1(b) above, in no event shall Landlord be:

               (a) bound by or liable for any rent paid by Subtenant to Tenant;
or any security deposit paid by Subtenant to Tenant that is not transferred to
Landlord;

               (b) liable for any act or omission of Tenant or for any default
of Tenant under the Sublease which occurred prior to Landlord's assumption;

               (c) subject to any defenses or offsets that Subtenant may have
against Tenant which arose prior to Landlord's assumption; or

<PAGE>


               (d) bound by any changes or modifications made to the Sublease
without the written consent of Landlord.

     5.   Non-Release of Tenant. Nothing contained in this Agreement or the
          ---------------------
Sublease shall be deemed to alter the primary liability of Tenant to pay the
Rent and perform all of Tenant's obligations under the Master Lease (including,
without limitation, the payment of all bills rendered by Landlord for charges
incurred by Subtenant for services and materials supplied to the Subleased
Premises), nor release Tenant from its obligations under the Master Lease, nor
waive any rights that Landlord may now have or later acquire against Tenant
under the Master Lease. The acceptance of any sums by Landlord from Subtenant or
any third party shall not be deemed a waiver by Landlord of Tenant's obligation
to pay Rent or any other amounts as provided in the Master Lease. The
performance of any obligation required of Tenant under the Master Lease by
Subtenant or any third party shall not be deemed a waiver by Landlord of
Tenant's duty to perform such obligation. Any act or omission by Subtenant or
any of its agents, employees or invitees in, on, or about the Premises or the
Building, or any act by Subtenant or any of its agents, employees or invitees
pursuant to the terms and conditions of the Sublease, shall constitute the act
or omission of Tenant. Any sums that may be payable under the Master Lease by
virtue of any act or omission of Subtenant shall be the obligation of Tenant to
pay and discharge in accordance with the terms of the Master Lease.

     6.   Further Transfers. The consent of Landlord is limited solely to the
          -----------------
Sublease. Any assignment of the Master Lease or the Sublease or further
subletting of any part of the Premises shall be subject to Landlord's consent as
provided in the Master Lease. Landlord may consent in its absolute and sole
discretion to subsequent subleases and assignments of the Sublease or any
amendments or modifications to the Sublease without notifying Tenant or anyone
else liable under the Master Lease, and without obtaining their consent. No such
action by Landlord will relieve those persons from any liability to Landlord or
otherwise with regard to the Subleased Premises, and Tenant and Subtenant, waive
any provision of California law to the contrary, including without limitation
Sections 2787 to 2855, inclusive, of the California Civil Code. In addition, no
provision of the Sublease or this Agreement shall limit Landlord's right, in the
event of a proposed future assignment or subletting of any portion of the
Premises, including the Subleased Premises, to recapture such portion of the
Premises, including the Subleased Premises, affected by that proposed assignment
or subletting, as provided in Section 14.1(c) of the Master Lease, or to receive
any payment required under Section 14.1(d) of the Master Lease, and, without
limiting the generality of any of any other provision of this Agreement relating
to the Sublease, no provision of the Sublease pertaining to sharing of excess
rentals or profits on further subletting shall in any way diminish or affect
Landlord's rights under Article 14of the Master Lease.

     7.   Conditions to Landlord's Consent. Landlord's consent to the Sublease
          --------------------------------
is expressly conditioned on the following:

          7.1 Prior to the Subtenant's taking occupancy of the Subleased
Premises, Tenant shall deliver to Landlord certificates of insurance evidencing
Subtenant's compliance with Section 9.1 of the Master Lease and indicating that
Landlord is named as an additional insured on such policies.

          7.2 Tenant shall reimburse Landlord for (a) the reasonable expenses
incurred by Landlord in connection with Tenant's request for such consent,
including attorneys' fees and disbursements, the costs of investigating the
acceptability of Subtenant, and any leasing or brokerage commissions, and (b)
all reasonable direct and indirect expenses incurred by

<PAGE>

Landlord due to Subtenant taking possession of the Premises, including, but
not limited to, costs relating to freight elevator operation, security service,
janitorial service and rubbish removal (collectively, "Transfer-Related Costs").
                                                       ----------------------
Tenant shall reimburse Landlord for the Transfer-Related Costs incurred by
Landlord within ten (10) days following Tenant's receipt of an invoice.

          7.3 Tenant shall pay to Landlord as and when required under the Master
Lease, the amounts set forth in Section 14.1(D) of the Master Lease regarding
Subrent, and upon request by Landlord, Tenant shall provide Landlord with
reasonable documentation of Tenant's payment of the Permitted Transfer Costs and
Tenant's calculations of the Subrent.

          7.4 Neither Landlord nor the other Indemnitees (as defined below)
shall be liable to Subtenant or to any of Subtenant's Agents (as defined in
Section 1.4 of the Master Lease), and Subtenant waives all claims against
Landlord and such other Indemnitees, for any injury to or death of any person or
for loss of use of or damage to or destruction of property in or about the
Premises or Project by or from any cause whatsoever, including without
limitation, earthquake or earth movement, gas, fire, oil, electricity or leakage
from the roof, walls, basement or other portion of the Premises or Project,
except only, with respect to any Indemnitee, to the extent such injury, death or
damage is caused by the gross negligence or willful misconduct of such
Indemnitee and not covered by the insurance required to be carried by Subtenant
under the Sublease and hereunder or except to the extent such limitation on
liability is prohibited by law. The provisions of this Section 7.4 shall survive
the expiration or earlier termination of the Sublease until all claims within
the scope of this Section 7.4 are fully, finally, and absolutely barred by the
applicable statutes of limitations.

          7.5 Subtenant shall hold harmless, indemnify and defend Landlord, and
its employees, agents and contractors (the "Indemnitees"), on the terms and
conditions contained in Section 10.3 of the Master Lease, as if the term
"Subtenant" were substituted for "Tenant" therein.

     8.   Representations of Tenant and Subtenant.
          ---------------------------------------

          8.1 Tenant and Subtenant represent and warrant to Landlord that a true

property, goodwill, intangible property and/or any capital stock or other equity
ownership of Tenant).

relief, then the party which prevails in such action shall be entitled to its
reasonable attorneys' fees and expenses related to such action, in addition to
all other recovery or relief. A party shall be deemed to have prevailed in any
such action (without limiting the generality of the foregoing) if such action is

performance of obligations allegedly not complied with, or if such party obtains
substantially the relief sought by it in the action, irrespective of whether
such action is prosecuted to judgment. Attorneys' fees shall include, without
limitation, fees incurred in discovery, contempt proceedings, and bankruptcy
litigation. The non-prevailing party shall also pay the attorneys' fees and
costs incurred by the prevailing party in any post-judgment proceedings to

judgment on this Agreement.

execute and deliver such further customary documents and/or instruments and
perform such further customary acts as may be required to give full effect to
the transaction herein contemplated.

respective meanings ascribed to them in the Master Lease. Captions to the
paragraphs and sections in this Agreement are included for convenience only and
do not modify any of the terms of this Agreement. No one party shall be deemed
to have drafted this Agreement and it shall be construed according to its fair
meaning and not against any party. All indemnity obligations under this
Agreement and any other provision hereof the survival of which is necessary to
its enforcement shall survive the expiration or earlier termination of the
Sublease and this Agreement.

3.  Term.

    3.1  Term. The term (the "Term") of this Sublease shall be for eighteen (18)

ending on March 31, 2003, unless sooner terminated pursuant to any provision

Sublessor's inability to obtain consent of the Master Lessor before commencement
of October 1, 2001 or for any reason whatsoever on or before October 15, 2001,
then, in addition to Sublessee's other rights and remedies, Sublessee may
terminate the Sublease by written notice to Sublessor, whereupon any monies
previously paid by Sublessee to Sublessor shall be reimbursed to Sublessee, or,
at Sublessee's election, the date Sublessee is otherwise obliged to commence
payment of rent shall be delayed by one (1) day for each day that the

4.  Rent. Sublessee shall pay to Sublessor as rent for the Premises equal

of said deposit, Sublessee shall within ten (10) days after written demand

         under the Sublease. Sublessor agrees that Sublessee shall have the

         consent to this Sublease.

     9.3 In the event that Master Lessor does give such consent then:

of the obligations of Sublessor to be performed under the Master Lease.

liable under the Master Lease shall not be deemed a waiver by Master Lessor of
any provisions of the Master Lease.

     (c) The consent of this Sublease shall not constitute a consent to any
subsequent subletting or assignment.

     (d) In the event of any default of Sublessor under the Master Lease, Master
Lessor may proceed directly against Sublessor, any guarantors or any one else
liable under the Master Lease or this Sublease without first exhausting Master
Lessor's remedies against any other person or entity liable thereon to Master
Lessor.

     (e) Master Lessor may consent to subsequent sublettings and assignments of
the Master Lease or this Sublease or any amendments or modifications thereto
without notifying Sublessor nor any one else liable under the Master Lease and
without obtaining their consent and such action shall not relieve such persons
from liability.

    (f)  In the event that Sublessor shall default in its obligations under the
         Master Lease, then Master Lessor, at its option and without being
         obligated to do so, may require Sublessee to attorn to Master Lessor in
         which event Master Lessor shall undertake the obligations of Sublessor
         under this Sublease from the time of the exercise of said option to but

         the Sublessor under the Sublease unless continuing.

         the end of this document shall constitute their consent to the terms of
         this Sublease.

    9.5  Master Lessor acknowledges that, to the best of Master Lessor's
knowledge, no default presently exists under the Master Lease of obligations to
be performed by Sublessor nor has there occurred any event which with the
passage of time or giving of notice or both would constitute a default under the
Master Lease, and that the Master Lease is in full force and effect.

    9.6  In the event that Sublessor defaults under its obligations to be
performed under the Master Lease by Sublessor, Master Lessor agrees to deliver
to Sublessee a copy of any such notice of default. Sublessee shall have the
right to cure any default of Sublessor described in any notice of default within
ten (10) days after service of such notice of default on Sublessee. If such
default is cured by Sublessee then Sublessee shall have the right of
reimbursement and offset from and against Sublessor.
