                                    RECITALS

         Landlord is the  landlord  and Tenant is the tenant  under that certain

(the  "Premises").  The Premises  consists of 8,069 rentable  square feet (being
4,483 rsf  office,  586 rsf  warehouse  and 3,000 rsf lab).  As used  herein the
"Amended Lease" shall mean the Initial Lease as amended by First Amendment,  and
the "Lease" shall mean the Amended Lease as modified by this Second Amendment.

         The parties  desire to amend the Amended Lease to extend the Lease Term
and make certain other changes, on the following terms and conditions.

         Except as otherwise  specifically  defined herein all capitalized terms
shall have the meanings assigned in the Initial Lease.

                                    AGREEMENT

1.  EXTENDED  TERM OF THE LEASE.  Section  1(g) of the  Initial  Lease is hereby
amended to extend the Term of the Lease for a term ("Extended  Term") commencing
on September 1, 2006  ("Extended  Term  Commencement  Date") and  terminating on
August 31, 2007 ("Expiration Date").

2. BASE  MONTHLY  RENT.  From and after the  Extended  Term  Commencement  Date,
Section  1(h) of the Initial  Lease hereby is amended such that the Base Monthly
Rent during the Extended Term is as follows:

                                                        G/ 142          H/161
                                                        ------          -----
Extended Term Commencement Date - August 31,           $8,736.00      $2,125.00
2007

hereby amended to reduce the Project Area to an agreed 361,439  rentable  square
feet and Exhibit B to

<PAGE>

the Initial Lease is replaced by Exhibit A to this Second Amendment.

4. As IS;  LANDLORD'S WORK.  Tenant leases the Premises during the Extended Term
in its as-is,  where-is  condition and acknowledges that Landlord has not agreed
to and shall not be  required to make any  improvements  or  alterations  to the
same.

5.  OPTION TO RENEW.  Tenant is hereby  granted  the right to extend the Term of
this  Lease  beyond  the  Expiration  Date  of the  Extended  Term  for  one (I)
successive period of twelve (12) months (the "Second Extended Term"). This right
to extend may be  exercised  by Tenant only by giving  Landlord  written  notice
("Notice")  on or before  February  28,  2007.  If Tenant has  defaulted  in its
obligations  under  this  Lease,  and  failed to cure such  defaults  within any
applicable  cure period,  then Tenant's right to extend the Lease for the Second
Extended Term shall automatically terminate.  Tenant's right to extend the Lease
for the Second  Extended  Term is personal to Tenant and may not be exercised by
any subtenant or assignee of Tenant.  Tenant's  extension  rights shall apply to
all of the Premises  then leased by Tenant under this Lease.  From and after the
commencement  of the Second  Extended  Term,  all of the terms,  covenants,  and
conditions  of the Lease  shall  continue  in full force and effect as  written,
except that Sections 5, and 6 of this Second Amendment shall be deleted in their
entirety and Base Monthly  Rent for the Second  Extended  Term shall be -at the-
rate - then - being - paid- - under-new-  new-leases-  for - similarly  improved
and situated  premises in the Canyon Park Business  Center of which this Project
is a part,  but not less than the Base Monthly Rent in effect for the last month
of the Extended  Term.  Tenant shall  include with its Notice copies of Tenant's
then-current  financial statement as well as financial statements from the three
(3) years prior to the  current  financial  statement  year,  and shall  provide
Landlord with such other financial  information regarding Tenant as Landlord may
require. Tenant's right to extend the Term of this Lease for the Second Extended
Term is  contingent  upon  Landlord's  reasonable  approval  of  such  financial
statements and information.

Tenant hereby  acknowledges and agrees that its renewal rights set forth in this
Section supersede and replace its renewal rights under Section 33 of the Initial
Lease,  which Tenant  failed to exercise and therefore are deemed void and of no
further force and effect.

6. RIGHT OF FIRST  OPPORTUNITY.  This Right of First  Opportunity shall apply to
Building G, Unit 140 of 22118 20th  Avenue SE,  Bothell,  Washington  98021 (the
"Expansion Space").  This Right of First Opportunity shall be subordinate to any
other pre-existing  tenant's expansion rights as of the date of mutual execution
of this Second  Amendment and Landlord  shall further be entitled to voluntarily
allow  existing  tenants to extend or renew  their  leases.  Except as  provided
above,  at  such  time as  Landlord  intends  to  offer  all or any  part of the
Expansion Space for lease,  Landlord shall so notify Tenant,  which notice shall
include the terms  (rate,  term,  etc.) on which  Landlord  intends to offer the
Expansion Space or part thereof (the "Offered Space"). If Landlord is offering a
portion of the  Expansion  Space in  conjunction  with  other,  adjacent  space,
Landlord may designate the entirety of such offered space as the Offered  Space.
Tenant shall have five (5)  business  days from receipt of such notice to notify
Landlord  that Tenant  agrees to enter into a lease for the Offered Space on the
terms stated in Landlord's notice or to enter into a lease for the Offered Space
on such other terms as may be mutually agreeable to Landlord and Tenant in their
sole discretion.  If Tenant does not enter into a lease for the Offered Space as
provided in the proceeding sentence, this Right of First

<PAGE>

Opportunity  immediately  and without further action by Landlord shall terminate
in its entirety.  This Right of First Opportunity shall be exercisable by Tenant
only if Tenant is in  possession  of the  Premises  under  this Lease and is not
then,  nor,  from  and  after  the  parties'  mutual  execution  of this  Second
Amendment,  ever has been,  in  default  beyond any  applicable  notice and cure
period under this Lease.  Notwithstanding  any other  provision of this Section,
this  Right of First  Opportunity  shall  expire on the  Expiration  Date of the
Extended Term or the earlier  termination of the Lease,  provided that if Tenant
exercises its Option to Renew, this Right of First Opportunity shall be extended
until the expiration or termination  of the Second  Extended Term.  Furthermore,
this  Right of First  Opportunity  shall be  personal  to Tenant  and may not be
exercised by any subtenant or assignee of Tenant.

7. BROKERS.  Tenant was represented in this Second Amendment transaction by Eric
Lonergan of Washington  Partners,  who shall be compensated by Landlord pursuant
to a  separate  written  agreement.  Except  for the  broker  set  forth  in the
preceding sentence, each party shall indemnify,  defend and hold the other party
harmless from and against all costs, expenses,  attorneys' fees, liens and other
liability for commissions or other  compensation  claimed by any broker or agent
claiming the same by, through, or under that party.

8. ENTIRE AGREEMENT.  This Second Amendment and the Amended Lease constitute the
entire agreement  between Landlord and Tenant with respect to the subject matter
of this Second Amendment.

9. FULL FORCE AND EFFECT.  Except as specifically set forth herein,  the Amended
Lease is and remains in full force and effect and binding on the parties. Tenant
confirms  that Landlord is not now and has not in the past been in default under
the Lease, and Tenant has no claim against Landlord for damages or offset of any
type.
