2.     PREMISES.
       --------

     2.1  Subject  to  the  provisions  of  paragraphs  2.2  through  2.4 below,
Sublessor  leases to Sublessee and Sublessee hires from Sublessor those premises
consisting  of  approximately  thirty-five  thousand  four  hundred  thirty-two
(35,432)  square  feet  of  space,  as more particularly shown in Exhibit B (the
"Premises"), on the third floor of that building commonly known and described as
2665 North First Street, San Jose, California (the "Building"). Sublessee agrees
to  accept  the  Premises  on  the  Commencement  Date  as  being  suitable  for
Sublessee's  intended  use  and in good operating order, condition and repair in
its  then  existing  "AS  IS"  condition.  Sublessor  makes  no  warranty  or
representation regarding the condition of the Premises. Sublessee shall have the
non-exclusive  right  to  use  its  pro  rata share of unreserved parking spaces
within  the  Office  Building  Project  pursuant to the provisions of the Master
Lease.

     2.2  For  the  first  one  hundred  and  eighty  (180) days of the Term the
Premises  shall  consist  of  the approximately fifteen thousand (15,000) square
feet  outlined  on  Exhibit  B attached hereto. Within sixty (60) days after the
Commencement  Date, Sublessor shall remove all of Sublessor's equipment from the
Lab  area, as shown on Exhibit B, and immediately upon such removal the Lab area
shall  become  part  of  the  Premises. Furthermore, Sublessor shall vacate Data
Center  2  shown  on Exhibit B and remove all of Sublessor's equipment from Data
Center  2  within  sixty  (60)  days  after  Sublessor's  receipt of Sublessee's
Financial  Notice (defined below). Immediately upon such vacation of Data Center
2, it will become part of the Premises. Prior to receiving Sublessee's Financial
Notice  (defined below), Sublessor will permit Sublessee to install two racks in
Data  Center  2  and  move  Sublessee's equipment to Data Center 2. Furthermore,
Sublessor  shall  vacate  the  network operations center shown on Exhibit B (the
"NOC"),  in  its  "AS IS" condition, but with all equipment in place, within one
hundred  fifty  (150)  days  after  Sublessor's receipt of Sublessee's Financial
Status  Notice  (defined  below). Immediately upon such vacation of the NOC, the
NOC  shall  become  part  of  the Premises. If Sublessor fails to vacate the NOC
within  such  150-day  period,  then the Base Rent allocable to the NOC shall be
abated  until  such  time  as  Sublessor has vacated the NOC. In addition to the

                                      E-4

Premises,  Sublessee  shall have the right to use, in common with Sublessor, the
Telco Room, the UPS Room and the men's and women's Restrooms as shown on Exhibit
B.

     Sublessee  shall  provide  forty-eight  hours  (48)  hours  prior notice to
Sublessor  of its desire to use the large conference room as shown in Exhibit B.
Such  notice shall include the time it desires to use the large conference room.
Sublessor  shall  respond  to  Sublessee  within  four (4) business hours of the
availability of the large conference room to Sublessee and shall make good faith
efforts  to  make  such  room  available  to  Sublessee.

     2.3  Sublessee acknowledges that during the Term of the Sublease, Sublessor
shall  retain the use of the Data Center 1 and the Raised Floor Lab, as shown on
Exhibit  B,  consisting  of approximately 700 square feet, and the Data Center 1
and  the  Raised  Floor  Lab  shall not be included in the Premises subleased to
Sublessee. Sublessee further acknowledges that Sublessee's use of the Telco Room
and  the UPS Room shall be shared with Sublessor. Sublessor reserves for itself,
its  agents,  employees and contractors, access to the Data Center 1, the Raised
Floor  Lab, the Telco Room, and the UPS Room through the Premises at any and all
times  during  the  Term of this Sublease and Sublessor shall not be required to
provide  Sublessee  with  prior  notice  of any such access. Sublessor shall use
commercially  reasonable  efforts  to minimize any interference that such access
may  cause  to  Sublessee's  use  of  the  Premises.

     2.4  On  or  before January 2, 2005, Sublessee shall provide Sublessor with
satisfactory evidence that (i) Sublessee has a current Net Cash Balance (defined
below)  of  not  less than Three Million Dollars ($3,000,000), or (ii) Sublessee
has  obtained  new  equity  financing  in  an  amount not less than Five Million
Dollars  ($5,000,000)  ("Sublessee's  Financial  Status  Notice"). Such evidence
shall  be  confirmed  by  a  U.S.  chartered  bank,  thrift  or  other financial
institution.  Within  ninety  (90) days after Sublessor's receipt of Sublessee's
Financial Status Notice, Sublessor shall vacate the balance of the Premises then
occupied by Sublessor, if any (other than the NOC and Data Center 1), and within
one  hundred  fifty (150) day after Sublessor's receipt of Sublessee's Financial
Status  Notice,  Sublessor  shall  vacate  the  NOC.

     2.5  Should  Sublessor  be  unable to vacate the Premises within the ninety
(90)  day  period  following  receipt  of  Sublesse's  Financial  Status  Notice
("Sublessor's Delay"), Sublessor shall have the right to extend its occupancy up
to an additional ninety (90) days by providing Sublessee thirty (30) day advance
written  notice  to Sublesse. In the event of Sublessor's Delay, Base Rent shall
continue  at  the  same  rate as rent due for months 1 through 6 as set forth in
paragraph  4.1  below. Upon Sublessor's vacating the Premises, the rent schedule
shall  resume  as  set  forth  in  paragraph  4.1  below.

3.     TERM.
       ----

     The  term  of  the Sublease ("Term") shall be approximately forty-five (45)
months,  commencing  on  the date (the "Commencement Date") that is the later of
(i)  the date the Sublease and Master Lessor's consent to the Sublease have been
fully  executed,  and  (ii)  September  1, 2004, and expiring May 31, 2008. Upon
determination  of  the  actual  Commencement  Date,  the parties shall execute a
memorandum  confirming  the  Commencement  Date.

4.     RENT.
       ----

     4.1  Sublessee  shall  pay  to  Sublessor as Base Rent for the Premises the

execution  hereof,  the  sum  of  Seventy-eight Thousand Seven Hundred Fifty and
no/100ths  Dollars ($78,750.00), which shall be applied to the Base Rent due for
the  first  five (5) months of the Term, plus additional Base Rent in the amount
of  ($47,250.00).  Commencing  on  the first day of the sixth (6`~) month of the
Term,  Base Rent shall be paid on or before the first day of each calendar month
of  the  Term  without  prior  notice,  demand,  deduction or offset whatsoever.

    Months  of  Term     Base  Rent
     1  through  6       $15,750.00/month

additional  rent,  Sublessee's pro rata share of the Operating Expense Increase,
in  the  manner  provided  in  the Master Lease. Sublessee acknowledges that the
monthly  Base  Rent  does not include utilities; therefore, Sublessee shall also
pay  to Sublessor on a monthly basis Sublessee's pro rata share of all utilities
(gas  and electricity) supplied to Suite 300, within ten (10) days after receipt
of  a  statement  from  Sublessor.  Sublessee's pro rata share of such utilities
charges  shall  be based upon the ratio of the area of the Premises to the total
area  of  Suite 300 (35,432 sq. ft.). The term "Rent" when used in this Sublease
shall  mean  the  Base  Rent  and any and all additional rent payable under this
Sublease.  Rent  for any fractional part of a calendar month at the commencement
or  expiration  of  the  Term  shall be a prorated amount of the Rent for a full
calendar  month  based  upon  a  thirty  (30)  day  month.

       ----------

     Sublessor  represents to Sublessee that Sublessor has been given possession
of  the Premises pursuant to the Master Lease. Sublessor shall tender possession

Sublessor  a  cash  deposit  ("Security  Deposit")  in  the amount of Fifty-five
Thousand Five Hundred Dollars ($55,500) as security for the faithful performance
by Sublessee of all of Sublessee's obligations under this Sublease. If Sublessee
is  in  default under this Sublease, Sublessor may, but without obligation to do
so,  use  or  apply  all  or  any  portion of the Security Deposit to the extent
necessary  to  cure  the  default  or  to  compensate  Sublessor  for all damage
sustained  by Sublessor as a result of Sublessee's default. If Sublessor uses or
applies  any portion of the Security Deposit for such purposes, Sublessee shall,
within  five  (5) days after demand from Sublessor, restore the Security Deposit
to  its  original  amount.  Provided that Sublessee is not in default under this

                                      E-6
<PAGE>

Sublease,  Sublessor  shall  comply  with  the  provisions  of  the Master Lease
regarding  the  return of the Security Deposit to Sublessee. Sublessee shall not
at  any  time  be  entitled  to  interest  on  the  Security  Deposit.

     6.2  On  or  before  January  2, 2005 Sublessee shall deposit an additional
Seventy  Thousand  One  Hundred  Eleven  and 20/100ths Dollars ($70,111.20) with
Sublessor  to  increase the Security Deposit to One Hundred Twenty-five Thousand
Six  Hundred  Eleven  and  20/100ths Dollars ($125,611.20). If at any time after
January  2,  2005, Sublessee's Net Cash Balance falls below Four Million Dollars
($4,000,000),  then  the  Security  Deposit  shall  be  increased to One Hundred
Sixty-seven Thousand Four Hundred Eighty-one and 60/100ths Dollars ($167,481.60)
and  Sublessee  shall  deliver  the  difference between such amount and the then
current  balance  of  the Security Deposit to Sublessor within five (5) business
days after Sublessor's written request therefor. If at any time after January 2,
2005,  Sublessee's  Net  Cash  Balance  falls  below  Three  Million  Dollars
($3,000,000),  then  the Security Deposit shall be increased to Two Hundred Nine
Thousand  Three  Hundred Fifty-two Dollars $209,352) and Sublessee shall deliver
the  difference between such amount and the then current balance of the Security
Deposit  to  Sublessor  within  five (5) business days after Sublessor's written
request  therefor.

     6.3  For  purposes of this Lease, Sublessee's "Net Cash Balance" shall mean
Sublessee's  total unrestricted cash balances in any open bank accounts less all
debt. Sublessor shall have the right to request bank verification of Sublessee's
Net  Cash  Balance  on  a  quarterly  basis,  and  Sublessee  shall provide such
information to Sublessor within five (5) business days after Sublessor's written
request  therefor.

8.     ASSIGNMENT  AND  SUBLETTING.
       ---------------------------

     Any  further  subletting of the Premises or any assignment of this Sublease
shall be subject to the terms and conditions of the Master Lease which have been
incorporated  herein  by  reference.

9.     OTHER  PROVISIONS  OF  SUBLEASE.
       -------------------------------

     9.1  Except  as  provided in this Sublease, all terms and conditions of the
Master  Lease  are  incorporated  into  and  made  a part of this Sublease as if
Sublessor  were  the  "Lessor" thereunder and Sublessee the "Lessee" thereunder,
except  that  (i)  the  following  shall be excluded: paragraphs 1.1, 1.2, 1.4 -
1.10, inclusive, 4.1, 6.1, 8.2, 15, 17, 23, 48, 50-54 inclusive, 56, 58, 60, 64,
65;  Exhibit  C  to  the  Master Lease; and each of the amendments to the Master
Lease; and (ii) all references to "Lessor" in paragraphs 7.1, 8.4, 9 and 11.1 of
the  Master Lease shall be deemed to refer to Master Lessor. Notwithstanding the
fact  that  a provision of the Master Lease is not made a part of this Sublease,
this Sublease is nevertheless subject and subordinate to all of the terms of the
Master  Lease.

                                      E-7
<PAGE>

     9.2  Sublessor  represents to Sublessee that, as of the Effective Date, (i)
the  Master Lease is unmodified and in full force and effect, (ii) Sublessor, to
Sublessor's  knowledge,  is  not  in  default  under  the Master Lease, (iii) to
Sublessor's  knowledge,  no event has occurred or is occurring that would result
in  Sublessor's  default  under  the  Master  Lease,  and  (iv)  to  Sublessor's
knowledge,  the  Master  Lessor  is  not  in  default  under  the  Master Lease.

     9.3  Notwithstanding  the  foregoing  incorporation  of  the  Master Lease,
Sublessor  shall not be responsible for the performance or the furnishing of any
maintenance,  repair,  replacement  or  other  obligations  or  services  to  be
performed  or furnished by Master Lessor under the Master Lease. Sublessor shall
not  be  liable  to  Sublessee for any failure by Master Lessor under the Master
Lease  to  perform its obligations or to furnish any services or utilities to be
furnished  by  Master  Lessor  under the Master Lease, nor shall such failure by
Master  Lessor  under  the  Master  Lease excuse performance by Sublessee of its
obligations  under  this  Sublease  except  to  the extent the failure by Master
Lessor  excuses  performance  by  Sublessor  under the Master Lease. In no event
shall  Sublessor  be  deemed to have granted to Sublessee any right greater than
Sublessor  had  the  power  to  grant  under  the  Master  Lease.

     9.4  Except  as  otherwise  provided  in this Sublease, Sublessee agrees to
observe, comply with, and perform, all of the terms and conditions applicable to
Sublessor  as  Tenant  under the Master Lease, except that the obligation to pay
Rent  to  Master  Lessor under the Master Lease shall be considered performed by
Sublessee  to  the  extent  and  in  the  amount  Rent  is  paid to Sublessor in
accordance  with  this Sublease. Sublessee shall not commit or suffer any act or
omission  by  Sublessee  or by any sub-sublessee or assignee of Sublessee, or by
their  respective  employees,  agents, contractors, representatives or invitees,
that  will  violate  any  of  the  provisions  of  the  Master  Lease.

     9.5  If  the Master Lease terminates, this Sublease shall terminate and the
parties  shall  be  relieved  of any liability or obligation thereafter accruing
under  this Sublease, except as otherwise expressly provided in the Master Lease
or  this  Sublease.  Notwithstanding the preceding sentence, if the Master Lease
terminates  as  a  result of a default or breach by Sublessor or Sublessee under
this Sublease and/or the Master Lease, then the defaulting party shall be liable
to  the  nondefaulting  party  for  the  damage  suffered  as  a  result of such
termination.

     9.6  If  the Master Lease gives Sublessor any right to terminate the Master
Lease  in the event of the partial or total damage, destruction, or condemnation
of the Premises or the building or Project of which the Premises are a part, the
exercise  of  such  right  by Sublessor shall not constitute a default or breach
hereunder,  provided  that  Sublessor  shall  give Sublessee written notice (the
"Termination  Notice")  of  Sublessor's  intent  to  exercise  such  right  of
termination  at least thirty (30) days in advance of such exercise, and any such
exercise  of  the  right  to  terminate by Sublessor further shall be subject to
Sublessee's  prior  written  approval, which shall not unreasonably be withheld.
If,  within  twenty  (20) days after receiving the Termination Notice, Sublessee
fails  to  deliver  to  Sublessor its written disapproval of such termination by
Sublessor  (Sublessee's  approval shall not unreasonably be withheld), Sublessee
conclusively  shall  be  deemed  to  have  consented  to  such  termination.

10.     SUBLESSOR'S  OBLIGATIONS.
        ------------------------

     Sublessor  agrees that Sublessee shall be entitled to receive all services,
utilities  and repairs to be provided by Master Lessor under the Master Lease to
Sublessor.  Sublessee  shall look solely to Master Lessor under the Master Lease
for all such services and utilities and shall not, under any circumstances, seek
or  require  Sublessor to perform any of such services or provide any utilities,
nor  shall  Sublessee  make  any  claim upon Sublessor for any damages which may
arise  by reason of Master Lessor's default under the Master Lease except to the
extent  such  default  is  caused  by  Sublessor. Any condition resulting from a
default  by Master Lessor under the Master Lease (other than a default caused by
Sublessor)  shall not constitute as between Sublessor and Sublessee an eviction,
actual  or constructive, of Sublessee and no such default shall excuse Sublessee
from  the performance or observance of any of its obligations to be performed or
observed  under  this Sublease, or entitle Sublessee to receive any reduction in
or  abatement  of  the  Rent provided for in this Sublease, except to the extent
Sublessor  receives an abatement in its Rent under the Master Lease with respect
to  the  Premises.  Sublessor shall promptly give written notice to Sublessee of
any  abatement  in  Rent  Sublessor  receives  from  Master  Lessor, or to which
Sublessor  believes  it  is  entitled.

and  subject  to the right, if any, of Sublessee to cure any such default within
any  applicable cure period, shall have available to it against Sublessee all of
the  remedies  available to Master Lessor under the Master Lease in the event of
such  a  default  on  the  part  of  Sublessor  thereunder.

12.     CONDITION  TO  SUBLEASE.
        -----------------------

without  limitation,  the agreements, terms covenants or conditions set forth in
the  Master  Lease  which  are incorporated in this Sublease) to be performed or
observed  by  Sublessee  after  the  Effective  Date.

     13.3  The foregoing indemnities shall survive any expiration or termination
of  this  Sublease,  and  are  in addition to the provisions of the Master Lease
incorporated  herein.

14.     TELEPHONE  SYSTEM.
        -----------------

     Sublessor  shall  notify  Sublessee fifteen (15) days prior to vacating the
Premises  whether  Sublessee  shall  be  permitted to use the existing telephone
system in the Premises. If Sublessor so notifies Sublessee, then Sublessee shall
be  permitted  to  use the existing telephone system, including telephone switch
and  headsets,  at no additional cost during the Term of the Sublease. Sublessor
makes  no  representations or warranties to Sublessee regarding the condition of
the telephone system, including its fitness for any particular purpose. Upon the
expiration or sooner termination of this Sublease, Sublessee shall surrender the
telephone  systems to Sublessor in the same condition as received, ordinary wear

use,  at  no additional cost to Sublessee, the furniture and equipment described
on  Exhibit  C  attached  hereto  (collectively,  the  "Equipment").  Sublessee
acknowledges  that, as disclosed by Exhibit C, some of the Equipment is owned by
Sublessor ("Sublessor's Equipment") and some of the Equipment is owned by Master
Lessor.  Sublessee  shall  use the Equipment only for the purposes for which the

received,  ordinary  wear and tear excepted. Sublessee shall reimburse Sublessor
for  the  full  replacement  cost  of  any  item of Equipment not surrendered to
Sublessor  in accordance with the provisions of this Sublease. To the extent any
item of the Equipment is damaged or destroyed, Sublessee shall, at its sole cost
and  expense,  promptly  repair  such  damage  or replace such destroyed item of
Equipment.  The  Equipment shall not be used by any one other than Sublessee and
its  employees,  agents,  contractors,  and invitees. The Equipment shall at all
times remain the property of Sublessor and Master Lessor, subject to Sublessee's
right to use the Equipment on the terms and conditions stated herein and subject
further  to  the provisions of paragraph 15.3 below. In no event shall Sublessee
pledge the Equipment or Sublessee's rights hereunder as security for any loan or

shall  also  be  subject  to the provisions of paragraph 61 of the Master Lease.

     15.2  Sublessee  shall maintain in full force and effect during the Term of
this  Sublease,  at  Sublessee's sole cost and expense, a policy of special form
insurance  covering  the  Equipment  for the full replacement cost thereof. Such
policy  shall name Sublessor as the named insured thereunder and shall be issued
by  an insurance company reasonably acceptable to Sublessor, which consent shall
not  be  unreasonably  withheld.  Sublessee  shall  provide  Sublessor  with  a
certificate  of  insurance  evidencing  such  coverage prior to the Commencement
Date.

     15.3  Provided  that Sublessee is not in default under this Sublease at the
expiration  of  the  Term, Sublessee may, at Sublessee's option, purchase all or
any portion of Sublessor's Equipment from Sublessor at a price equal to the then
fair  market value of such Equipment. If Sublessee elects to purchase all or any
portion  of  Sublessor's  Equipment,  Sublessor  shall,  at Sublessee's request,
execute  and  deliver  to Sublessee a bill of sale transferring all right, title
and  interest  of  Sublessor  in and to such portion of Sublessor's Equipment to
Sublessee,  without any warranties or guaranties whatsoever. Sublessee agrees to
accept Sublessor's Equipment in its then present condition, "AS IS," without any
warranties or guaranties whatsoever, including any warranties of merchantability
or  fitness  for  any  particular  purpose.

16.     SUBLESSOR'S  OPTION  TO  TERMINATE.
