          2.1 Agreement to Lease. Landlord agrees to lease to Tenant and Tenant
agrees to lease from Landlord a portion of the first floor of the building
described above (the “Building”) as depicted on the floor plan attached hereto
as Exhibit A (the “Premises”) together with a non-exclusive license to use all
common areas of the Building and the real property on which it is located (the
“Property”) for their intended purposes, including all parking areas,
accessways, driveways, and other improvements on the Property as provided by
Landlord from time to time for the general use and enjoyment of tenants in the
Building. Landlord reserves the right to alter or change the present
configuration and capacity of the common areas from time to

SECURITIES AND EXCHANGE COMMISSION.]

time provided that no changes shall prevent Tenant’s access to or use of the
Premises. The Premises, Building, and Property are part of Quadrant Monte Villa
Center (the “Business Park”).

          2.2 Measurement. Landlord and Tenant acknowledge and agree that as of
the Effective Date the Premises are deemed to contain the number of RSF set
forth in Section 1 above and such number shall be final and binding on the
parties for all purposes under this Lease. Landlord and Tenant accept the
foregoing calculation and no remeasurement shall be required or permitted
hereunder; provided, however, that if a physical change in the size of the
Premises or the Building occurs, Landlord may cause a non-affiliated third party
architect selected by Landlord to remeasure the Premises and the Building in
accordance with Landlord’s standard methodology employed in the Building and
such calculation shall be binding on the parties. If Tenant objects to
Landlord’s remeasurement calculation, Tenant may, at Tenant’s expense have an
independent architect remeasure the Premises using the same methodology. If the
two architects calculations differ then the parties shall work in good faith to
resolve the dispute.

          2.3 Right of First Refusal. If any space in the Building becomes
available for lease (i.e., is vacant or reasonably expected to become vacant) at
any time during the Term and Tenant is not then in default under this Lease
beyond any applicable notice, grace or cure periods, Tenant shall have a
continuing right of first refusal (“RFR”) to lease such space when it becomes
available, subordinate to any rights that Ceptyr, Inc. or its successors or
assigns may have to lease such space. Tenant’s RFR shall not apply to any space
if the existing occupant of such space elects to renew or extend its lease at
any time and Landlord shall not be required to offer any space to Tenant before
entering into a renewal or extension with the existing occupant. Landlord shall
give Tenant written notice when it determines that space in the Building has or
will become available and Tenant shall have ten (10) Business Days after receipt
of such notice to deliver irrevocable notice to Landlord of its intent to add
such space to the Premises on the date the space becomes available. Tenant may
only elect to exercise the RFR with respect to the entire increment of space
offered to Tenant, provided that if Landlord thereafter decides to offer smaller
increments of the space to potential tenants, Landlord shall provide a notice to
Tenant and Tenant may elect to exercise its RFR with respect to such smaller
increment within ten (10) days after the date of such notice from Landlord. If
Tenant does not timely exercise its RFR, Landlord shall have the right to lease
the space in question to any third party upon such terms and conditions as
Landlord deems appropriate and shall not be required to offer the space to
Tenant again until the subsequent tenant vacates the space.

     If Tenant exercises its RFR then the RFR Space shall be added to the
Premises upon all of the terms and conditions of this Lease except that (a)
Landlord shall deliver the RFR Space as soon as such space is available for
occupancy in its previously improved condition and shall have no obligation to
make any improvements or alterations to the space (including but not limited to
installation of multi-tenant corridors or common areas); (b) Landlord shall have
no obligation to provide any free rent or abated rent or to pay any real estate
commission on any such space; (c) the Base Monthly Rent applicable to such space
shall be the then in effect office or laboratory (as applicable) rent rate set
forth in Section 1 above; and (d) Tenant shall be entitled to an improvement
allowance equal to Fifteen Dollars ($15.00) per square foot of RFR space
multiplied by a fraction, the numerator of which is the number of months
remaining in the Initial Term at the time the space is added to the Premises and
the denominator of which is 120.

If Tenant exercises its right to include RFR Space in the Premises, Tenant’s
Share shall be adjusted and upon Landlord’s request, Tenant shall execute an
amendment to this Lease or other written confirmation documenting the new RSF in
the Premises, Tenant’s Share of the Building and the applicable Base Monthly
Rent for such space.

     3. Term.

          3.1 Initial Term. The initial term of this Lease (“Initial Term”)
shall commence on the Commencement Date set forth in Section 1, provided that if
Landlord is unable to deliver possession of the Premises to Tenant by March 30,
2006, for any reason not caused by force majeure or Tenant, Tenant may elect to
terminate this Lease by written notice to Landlord within ten (10) days
thereafter. Upon request by either party, the parties shall execute a written
acknowledgement setting forth the actual Commencement Date and Expiration Date.
Except as otherwise provided herein, all of the covenants and conditions of this
Lease shall be binding on the parties as of the Effective Date of this Lease.

          3.2 Expiration. The Initial Term shall expire on the Expiration Date
set forth in Section 1, unless sooner terminated or extended as provided in this
Lease. As used herein, “Term” shall mean the Initial Term and the Extended Term
if Tenant validly exercises its Extension Option.

          3.3 Option to Extend Term. Tenant shall have one (1) option (the
“Extension Option”) to extend the Term of this Lease for an additional five (5)
years immediately following the Initial Term (the “Extended Term”). The
Extension Option may be exercised by Tenant only by irrevocable written notice
of exercise delivered to Landlord no later than nine (9) months prior to the
Expiration Date. If Tenant does not deliver a notice of exercise by such date
then the Extension Option shall immediately terminate and be of no further force
or effect and this Lease shall terminate at the end of the Initial Term.
Tenant’s Extension Option shall be personal to Tenant and any Permitted
Transferee (as defined in Section 17.3) and may not be exercised by or for the
benefit of any other assignee or subtenant. Tenant may not exercise the
Extension Option if on the date of such notice Tenant is in default (after any
required notice and expiration of any applicable cure period) under this Lease.
If Tenant becomes in default (after any required notice and expiration of any
applicable cure period) under this Lease after exercise of the Extension Option
but before the Expiration Date of the Initial Term, Landlord may, in addition to
its other remedies under this Lease, elect to terminate such extension by notice
in writing to Tenant, whereupon the Term shall expire without any such
extension.

               3.3.1 Upon Tenant’s valid exercise of the Extension Option, the
parties shall be obligated under all the terms and conditions of this Lease
through the Extended Term, except that (i) Base Monthly Rent shall be adjusted
as provided in Section 3.3.2, (ii) Landlord shall have no obligation to alter
the Premises or pay any tenant improvement or refurbishment allowance for the
Extended Term, and (iii) Tenant shall not have any additional rights to extend
the Term.

               3.3.2 Base Monthly Rent during the Extended Term for any portion
of the Premises built out for laboratory use shall be equal to Thirty-one and
83/100 Dollars

[*CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS

($31.83) per RSF in the first year of the Extended Term and shall increase
annually during the Extended Term by three percent (3%) per year.

               3.3.3 Base Monthly Rent during the Extended Term for any portion
of the Premises built out for office use shall be equal to ninety-five percent
(95%) of the then fair market rent (including periodic rent increases) for the
office space in the Bothell market, determined in accordance with this Section.
“Fair Market Rent” as of any date shall mean the per-square-foot rental rate for
a direct lease for space comparable to the Premises, leased for a comparable
term, with comparable uses, with comparable quality improvements and shell and
core construction, in comparable Class A projects in the Bothell Market Area,
taking into consideration: location in the Building or other building, extent of
service provided or to be provided, the ownership of the comparable space, the
time the particular rate under consideration became or is to become effective
and any other relevant terms or conditions but excluding any consideration of
Landlord’s transaction costs or savings.

               3.3.4 Approximately six (6) months prior to the commencement of
the Extended Term, Landlord shall propose a Base Monthly Rent schedule for the
office space for the Extended Term. Failure on the part of Landlord to give such
notice in a timely manner shall not vitiate the right to require adjustment of
Base Monthly Rent, but such delay shall result in deferral of the adjustment to
the date that is ninety (90) days after the date of such notice. The parties
shall negotiate in good faith, but if they are unable to agree upon such Base
Monthly Rent schedule within thirty (30) days after the delivery of Landlord’s
proposal, Tenant may by written notice demand arbitration within thirty (30)
days after receipt of notice from Landlord of Landlord’s determination of Fair
Market Rent. If no arbitration demand is delivered, Tenant shall be deemed to
have accepted the Fair Market Rent as determined by Landlord. If Tenant elects
to arbitrate, then unless otherwise agreed in writing by the parties, the matter
shall be submitted to arbitration in accordance with the terms of the following
paragraphs. The date on which Tenant gives its demand for arbitration is
referred to in this Lease as the “Arbitration Commencement Date”.

               3.3.5 Within fifteen (15) days after the Arbitration Commencement
Date, each party shall provide the other party with written notice (a “Rent
Notice”) of its determination of Fair Market Rent. The matter shall then be
submitted for decision to a single arbitrator or a panel of three (3)
arbitrators selected in accordance with this Section 3.3.4. Each arbitrator
appointed under this provision shall be an MAI certified appraiser with at least
ten (10) years professional appraising experience (including recent experience
in the Bothell market) who would qualify as an expert witness over objection to
give testimony addressed to the issue in a court of competent jurisdiction and
shall not have worked for or on behalf of either party during the three (3) year
period ending on the Arbitration Commencement Date. If Landlord and Tenant are
unable to agree on a single arbitrator within thirty (30) days after the
Arbitration Commencement Date, then each party shall select an arbitrator who
shall be qualified under the same criteria set forth above, and so notify the
other party in writing within fifteen (15) days after the end of such thirty
(30) day period. The two arbitrators so chosen by the parties shall then appoint
a third arbitrator within fifteen (15) days after the date of the appointment of
the last appointed arbitrator. If the two arbitrators so chosen by the parties
are unable to agree on the third arbitrator within such fifteen (15) day period,
the third arbitrator will be appointed by the director (or the equivalent) of
the Seattle office of the American Arbitration Association upon the

application of either party. If either party fails to timely select its
arbitrator and so notify the other party in writing within the foregoing fifteen
(15) day period, and the other party timely selects its arbitrator, then the
arbitrator selected by the other party shall be the sole arbitrator for
determining Fair Market Rent. If a third arbitrator is selected, then the
decision by a majority of the panel of three arbitrators shall determine Fair
Market Rent pursuant to this Section 3.3.

               3.3.6 Within thirty (30) days after the selection of the
arbitrator pursuant to Section 3.3.4 above, the arbitrator or arbitrators shall
determine Fair Market Rent by selecting either the Fair Market Rent stated in
Landlord’s Rent Notice or the Fair Market Rent stated in Tenant’s Rent Notice.
The determination of the arbitrator or arbitrators shall be limited to the sole
issue of whether the Fair Market Rent specified in Landlord’s Rent Notice or
Tenant’s Rent Notice is closest to the actual Fair Market Rent as determined by
the arbitrator or arbitrators. The arbitrator or arbitrators shall have no power
to average such amounts, modify the proposed rent schedules or to designate a
Fair Market Rent other than that specified in either Landlord’s Rent Notice or
Tenant’s Rent Notice.

               3.3.7 Both parties may submit any information to the arbitrator
or arbitrators for consideration, with copies to the other party. The arbitrator
or arbitrators shall have the right to consult experts and competent authorities
for factual information or evidence pertaining to the determination of Fair
Market Rent or to conduct a hearing. The arbitrator or arbitrators shall render
his, her or their decision by written notice to each party. The determination of
the arbitrator or a majority of the panel of three (3) arbitrators shall be
final and binding upon Landlord and Tenant. If there is only one arbitrator then
each party shall pay fifty percent (50%) of the cost of the arbitration. If
there are three arbitrators then each party shall pay the cost of its own
arbitrator and fifty percent (50%) of the cost of the third arbitrator.

               3.3.8 The award rendered in any such arbitration may be entered
in any court having jurisdiction and shall be final and binding between the
parties. The arbitration shall be conducted and determined in the City of
Seattle, Washington, in accord with the then-prevailing commercial arbitration
rules of the American Arbitration Association or its successor for arbitration
of commercial disputes except that the procedures mandated by said rules shall
be modified as set forth in this Section.

               3.3.9 If Tenant elects to arbitrate and the arbitration is not
concluded prior to the first day of the Extended Term, then Tenant shall pay
Base Monthly Rent to Landlord commencing on the first day of the applicable
Extended Term in an amount equal to the Fair Market Rent specified in Landlord’s
Rent Notice. If the amount of Fair Market Rent as determined by arbitration is
greater than or less than the Fair Market Rent specified in Landlord’s Rent
Notice, then any adjustment required to correct the amount previously paid shall
be made by payment by the appropriate party within ten (10) days after such
determination of Fair Market Rent.

     4. Delivery of Premises.

          4.1 As-Is. Landlord shall deliver the Premises to Tenant in its
current “as-is” condition with all faults promptly following execution of this
Lease and receipt of the Prepaid Rent and Letter of Credit required under
Section 6 below. Landlord shall not be required to

SERIES OF THREE ASTERISKS IN BRACKETS [***], HAS BEEN FILED SEPARATELY WITH THE

make any alterations or improvements to the Premises but shall pay the Allowance
pursuant to Exhibit B attached hereto. Tenant shall be responsible for all
construction or alterations of the Premises necessary to ready the Premises for
Tenant’s use and occupancy (the “Tenant Improvements”). All Tenant Improvements
shall be installed by Tenant in accordance with Exhibit B and Tenant shall not
begin construction until the terms and conditions of Exhibit B have been
satisfied. Tenant acknowledges that a portion of the Premises containing
approximately 1,000 square feet has been leased to Acucela on a month to month
basis. Landlord shall terminate the Acucela lease promptly after the Effective
Date and shall deliver possession of that portion of the Premises to Tenant
immediately upon surrender thereof by Acucela. Tenant shall not be required to
pay rent on the Acucela space until Landlord has delivered possession thereof to
Tenant.

          4.2 Limited Representations. As of the Effective Date to Landlord’s
actual knowledge, (a) the Building or the Premises or any equipment or systems
located therein do not violate any applicable Laws which, with respect to
building and land use codes, shall mean such Laws as they were interpreted and
applied at the time of construction or installation; and (b) the Building and
the Premises do not contain any Hazardous Materials (including asbestos and EMF
radiation) in levels or amounts that exceed permissible levels under applicable
Laws. As used herein, Landlord’s knowledge shall be limited to the current,
actual knowledge of R. Kirk Mathewson without any duty to investigate.

          4.3 Delayed Delivery. If Landlord for any reason cannot deliver
possession of the Premises to Tenant on the Effective Date, this Lease shall not
be void or voidable, nor shall Landlord be liable to Tenant for any loss or
damage resulting therefrom, provided that the five (5)-month free rent period
shall commence on the day Landlord delivers possession of the Premises to
Tenant.

     5. Rent.

          5.1 Base Monthly Rent. Tenant shall pay to Landlord the annual Base
Monthly Rent specified in Section 1 in equal monthly installments and the
Additional Rent as set forth in Section 8 and elsewhere in this Lease (the Base
Monthly Rent and the Additional Rent are collectively referred to as “Rent”).
Rent shall be paid in advance, on or before the first day of each calendar month
of the Term (except during the initial free rent period as provided in the rent
schedule set forth in Section 1.C). Except as expressly permitted herein, Rent
shall be paid without prior notice, demand, set off, counterclaim, deduction or
defense and, except as otherwise expressly provided in this Lease, without
abatement or suspension. As used herein, “Additional Rent” shall mean all sums
payable by Tenant hereunder other than Base Monthly Rent.

          5.2 Rent Commencement. Payment of Rent shall begin on the Commencement
Date. Rent for any period during the Term that is less than one month shall be
prorated for the actual number of days in such period.

          5.3 Address for Payments. All Rent shall be paid to Landlord at the
address for rent set forth in Section 1, in lawful money of the United States of
America, or to such other person or at such other place as Landlord may from
time to time designate in writing.

     6. Prepaid Rent and Letter of Credit.

          6.1 Prepaid Rent. Upon Tenant’s execution of this Lease, Tenant shall
pay to Landlord the Prepaid Rent set forth in Section 1 which shall be applied
to the first installments of Base Monthly Rent falling due hereunder.

          6.2 Letter of Credit. Upon Tenant’s execution of this Lease, Tenant
shall provide an irrevocable, fully assignable, and unconditional standby letter
of credit, issued by a financial institution reasonably acceptable to Landlord,
with a term continuing through the date that is sixty (60) days after the
Expiration Date, or, upon approval by Landlord with a term of at least one (1)
year with automatic renewal provisions, drawable by Landlord upon demand, and in
form and substance reasonably satisfactory to Landlord (the “Letter of Credit”).
The Letter of Credit shall be in an amount equal to Five Hundred Thousand
Dollars ($500,000). The Letter of Credit shall secure the full and faithful
performance of Tenant’s obligations under this Lease. Landlord may draw upon the
Letter of Credit in whole or in part as provided herein. Landlord may draw upon
the Letter of Credit without notice to Tenant if Tenant fails to deliver to
Landlord a renewal or extension of the Letter of Credit, in substantially the
same form or another form acceptable to Landlord in its sole discretion, for a
term of not less than one (1) year at least thirty (30) days prior to the
expiration date of the existing Letter of Credit. It shall be deemed reasonable
for Landlord to reject a financial institution hereunder if such financial
institution is not acceptable to Landlord’s lender. Tenant shall not assign or
encumber, or attempt to assign or encumber, the Letter of Credit and neither
Landlord nor its successors or assigns shall be bound by any such assignment,
encumbrance, attempted assignment, or attempted encumbrance. Landlord shall not
be required to exhaust its remedies against Tenant before having recourse to the
Letter of Credit or any cash security held by Landlord. Recourse by Landlord to
the Letter of Credit or other security shall not affect any remedies of Landlord
which are provided in this Lease or which are available to Landlord in law or
equity. In the event of a default by Tenant hereunder, Landlord may draw on the
Letter of Credit in accordance with its terms. Landlord may (but shall not be
required to) use all or any portion of the Letter of Credit or any proceeds
thereof to cure any defaults on the part of Tenant or to compensate Landlord for
any damage or costs Landlord incurs by reason of a default hereunder. In such
event, and upon written notice from Landlord to Tenant specifying the amount so
utilized by Landlord, Tenant shall immediately deposit with Landlord cash in
such amount or shall provide an amendment to the Letter of Credit to return the
Letter of Credit to the full amount required under this Lease. Within sixty (60)
days after expiration of the Term or earlier termination of this Lease (or such
longer period of time as is needed to confirm the existence of or cost to remedy
any default), provided no default is then outstanding, the Letter of Credit
proceeds (if Landlord has drawn on the Letter of Credit) shall be returned to
Tenant, reduced by those amounts that may be required by Landlord to remedy
defaults on the part of Tenant in the payment of Rent or otherwise, to repair
damages to the Premises caused by Tenant and to restore the Premises to the
condition required by this Lease. Landlord shall have no obligation to segregate
the Letter of Credit proceeds from its general funds or to pay interest thereon.
If Landlord conveys or transfers its interest in the Premises, and as a part of
such conveyance or transfer, assigns its interest in this Lease, then Tenant
shall take all steps necessary at Tenant’s expense to transfer the Letter of
Credit to Landlord’s successor and Landlord shall be released and discharged
from any further liability to Tenant with respect to the Letter of Credit or its
proceeds.

SECURITIES AND EXCHANGE COMMISSION.]

          6.3 Landlord’s Duty. Landlord’s obligations with respect to the Letter
of Credit and its proceeds are those of a debtor and not a trustee. Landlord may
maintain the proceeds separate from Landlord’s general funds or may commingle
the proceeds with other funds of Landlord. No interest shall accrue for Tenant
on the Letter of Credit proceeds.

     7. Use of Premises.

          7.1 Permitted Use. Tenant shall use and shall permit the use of the
Premises only for the purpose set forth in Section 1. Tenant shall not use the
Premises for any other purpose without Landlord’s written consent. Tenant
acknowledges that it has determined to its satisfaction that the Premises can be
used for those purposes. Tenant waives any right to terminate this Lease in the
event the Premises cannot be used for such purposes during the Term.

          7.2 Compliance With Insurance. Tenant shall not do or permit anything
to be done in or about the Premises or bring or keep anything therein which will
cause cancellation of any insurance policy covering the Building or any part
thereof or any of its contents. If Tenant’s specific use increases the cost of
insuring the Building then Tenant shall reimburse Landlord for the increased
cost within ten (10) days after Tenant’s receipt of Landlord’s written request
for reimbursement, which request shall be accompanied by reasonable evidence of
such cost.

          7.3 No Nuisance; Garbage Removal. Tenant shall not do or permit
anything to be done in or about the Premises that will obstruct or interfere
with the rights of other tenants or occupants of the Business Park or injure
them or their property, or use or allow the Premises to be used for any unlawful
purpose or in any way constituting a nuisance. Tenant may store garbage only in
the Premises or in exterior dumpsters reasonably approved by Landlord until it
its removed.

          7.4 Tenant’s Repairs and Maintenance. Subject to Sections 15 and 16,
Tenant agrees, at its sole cost, to repair and maintain the Premises, all parts
thereof, all loading docks contiguous thereto and all Tenant’s signs in good
order, condition and repair, ordinary wear and tear excepted, including keeping
the inside of all glass in doors and windows of the Premises clean, promptly
replacing any broken door or door closers and any cracked or broken glass with
glass of like kind and quality. Tenant shall maintain, repair, and replace as
and when necessary the mechanical systems or components thereof exclusively
serving the Premises (including HVAC) and all utility lines within the Premises,
including those within the exterior or demising walls, except to the extent such
items are to be maintained, repaired or replaced by Landlord pursuant to Section
10.1. Tenant shall not permit any vibration and noise which may be transmitted
beyond the Premises. When used in this Lease, the term “repair” shall include
making all necessary replacements, renewals, alterations and additions. All
repairs shall be at least equal in quality to the original work and shall be
made by Tenant in accordance with all applicable laws, ordinances and
regulations. Tenant shall provide its own janitorial service for the Premises in
accordance with specifications reasonably approved by Landlord. If Tenant fails
to perform any of its obligations under this Section 7.4, Landlord may, in
addition to exercising any other remedies provided herein, perform such repairs
or maintenance after notice to Tenant and expiration of the applicable cure
period. Any sums expended by Landlord in performing such repairs or maintenance
shall be due and payable as Additional Rent, within

SECURITIES AND EXCHANGE COMMISSION.]

ten (10) days after Tenant’s receipt of Landlord’s written request for
reimbursement, which request shall be accompanied by reasonable evidence of such
costs.

          7.5 Liens. Tenant shall keep the Premises and the Property free from
any liens arising out of any work performed, materials furnished or obligations
incurred by Tenant. If any lien shall be filed or claim of lien made for work or
materials furnished to Tenant, then Tenant shall, at its expense, within fifteen
(15) days after the filing thereof either: (a) discharge the lien or claim; or
(b) provide Landlord adequate security for the lien or claim and take steps to
contest the lien or claim in good faith by appropriate proceedings that operate
to stay its enforcement provided that Tenant must pay promptly any final adverse
judgment entered in any such proceeding. If Tenant does not comply with these
requirements, Landlord may discharge the lien or claim, and the amount paid, as
well as Landlord’s reasonable attorneys’ fees and other expenses incurred by
Landlord together with interest thereon, shall become additional rent payable by
Tenant on demand.

          7.6 Encumbrances. Tenant shall not cause or suffer to be placed, filed
or recorded against the title to the Premises (including any leasehold
improvements, alterations, additions, or improvements thereto), the Building or
the Property or any part thereof, any mortgage, deed of trust, security
agreement, financing statement or other encumbrance. Tenant shall not grant any
security agreement or financing statement covering the Premises or any part
thereof nor any leasehold improvements, alterations, additions, or improvements
thereto except that Tenant may pledge Tenant’s interest in any trade fixtures,
appliances and equipment which are not, and which do not become, a part of the
Premises. The form of any security agreement or financing statement which
includes a legal description of the Premises or the Project or the address
thereto, shall be subject to Landlord’s prior written approval, which approval
shall be subject to such conditions as Landlord may deem appropriate in
Landlord’s sole and absolute discretion. If Tenant files or permits the filing
of any such document without Landlord’s approval, Tenant shall cause such
statement to be terminated immediately upon request and shall indemnify and hold
Landlord harmless from any costs, losses or damages incurred by reason of such
filing.

          7.7 [***]

     8. Additional Rent for Operating Expenses.

          8.1 Tenant Payment. Beginning on the Commencement Date, Tenant shall
pay, as Additional Rent, all Operating Expenses. Operating Expenses shall be
payable on or before the first day each calendar month of the Term in the same
manner as Base Monthly Rent.

          8.2 Accounting. “Tenant’s Share” as of the Effective Date is set forth
in Section 1 above. Tenant’s Share shall be calculated by dividing the total RSF
of the Premises by the total RSF of the Building. An accounting period is a
calendar year, except the first accounting period shall commence on the
Commencement Date and end on December 31 of the same calendar year. The last
accounting period shall end on the Expiration Date of the Term. Annualized
Operating Expenses shall be prorated on a per diem basis for any accounting
period that is less than a full calendar year. If the average occupancy level of
the

12

 

[*CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS
DOCUMENT. EACH SUCH PORTION, WHICH HAS BEEN OMITTED HEREIN AND REPLACED WITH A
SERIES OF THREE ASTERISKS IN BRACKETS [***], HAS BEEN FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION.]

Building for any accounting period is not at full occupancy, then Operating
Expenses that vary with occupancy levels shall be adjusted by Landlord to
reflect those costs that would have been incurred had the Building been fully
occupied during such accounting period. Operating Expenses that do not vary with
occupancy levels (such as insurance and costs of operating that portion of the
HVAC system that serves the entire building) shall not be adjusted.

          8.3 Adjustment. Landlord may reasonably adjust the Operating
Expenses at the commencement of each new accounting period throughout the Term,
whereupon Tenant’s Additional Rent shall be adjusted accordingly. Annually,
Landlord shall furnish Tenant a written statement of the reasonably estimated
monthly Operating Expenses for the coming calendar year. Landlord may, by
written notice to Tenant, revise its estimate of Operating Expenses from time to
time.

          8.4 Reconciliation. By each April 30th, or as soon thereafter as
practicable, Landlord shall deliver to Tenant a written statement setting forth
the actual Operating Expenses during the preceding calendar year (or portion of
such calendar year after the Commencement Date). To the extent actual Operating
Expenses exceeded the estimated Operating Expenses paid by Tenant, Tenant shall
pay Additional Rent to Landlord within thirty (30) days after receipt of such
statement by Tenant and to the extent actual Operating Expenses were less than
the estimated Operating Expenses paid by Tenant, Tenant shall receive a credit
against its next payable Rent or such amount shall otherwise be refunded to
Tenant as Landlord determines in its sole discretion; provided, however, that as
to the last accounting period Tenant shall receive a refund at the time Landlord
delivers such statement to Tenant.

          8.5 Definition. “Operating Expenses” means all expenses and charges
incurred by Landlord in the operation, maintenance, repair and replacement of
the Building, Building systems, Property and common areas, as a first-class
facility, including without limitation the following costs by way of
illustration and not limitation: (i) all real property taxes, assessments and
other general or special charges levied during the Term by any public,
governmental or quasi-governmental authority against the real or personal
property included in the Building or the Property, including without limitation
Landlord’s personal property used in the maintenance, repair or operation of the
Building or the Property, or any other tax on the leasing of the Building or on
the rents from the Building (other than any federal, state or local income or
franchise tax) and including any reasonable costs associated with contesting any
tax assessment; (ii) any and all assessments, fees, charges and impositions
Landlord must pay for the Building, Property or Common Areas pursuant to the
CC&R’s, transportation or any other improvement monitoring or management plans,
or any other covenant, condition or reciprocal easement agreements; (iii)
electricity, gas and similar energy sources, refuse collection, water, sewer and
other utilities services for the Building and the Property not exclusively
serving a specific tenant; (iv) all licenses, permits and inspection fees; (v)
all costs and expenses relating to the Maintenance Obligations (as defined in
Section 9.1), the Services Obligations (as defined in Section 9.2) and Utility
Systems Repairs (as defined in Section 10.2), or relating to repair, maintenance
or replacement of the Specialized Equipment (as defined in Section 9.3); (vi)
all costs of improvements or alterations to the Building and Property which are
required by Laws, or which are intended to save labor or to reduce Operating
Expenses (provided that all capital improvements shall be amortized over a
reasonable period as determined by Landlord together with interest on the
unamortized balance from time to time at a per annum interest rate equal to

the Prime Rate in effect on the date such costs are incurred plus four percent
(4%)); (vii) all premiums and deductibles for liability, property damage,
casualty, automobile, rental loss, compensation or other insurance maintained by
Landlord relating to the Building or Property; (viii) the cost (amortized over a
reasonable period as determined by Landlord together with interest at a per
annum interest rate equal to the Prime Rate in effect on the date such costs are
incurred plus four percent (4%) on the unamortized balance) of any capital
improvements made to the Property or Building by Landlord for the replacement of
any Building equipment needed to operate the Building at the same quality levels
as prior to the replacement; (ix) costs incurred in the management or operation
of the Building and Property (including supplies), wages and salaries of
employees engaged in the management, operation and maintenance thereof and
payroll taxes and similar governmental charges with respect thereto which costs
shall be appropriately prorated if such persons work on projects or properties
other than the Property; (x) property management fees paid to independent or
affiliated contractors or to Landlord; (xi) legal, accounting and other
professional expenses directly related to the Building; (xii) landscaping and
painting and parking lot repairs, maintenance and resurfacing; (xiii) any other
expense or charge whether or not described above that in accordance with
generally accepted accounting principles and commercial property management
practices is properly an expense of maintaining, operating or repairing the
Building or Property. Operating Expenses shall not include any of the following:
(A) ground rent; (B) depreciation on the Building or equipment therein; (C) debt
service, including interest and amortization of funds borrowed by Landlord for
items other than capital improvements; (D) real estate broker’s commissions or

charitable or political contributions or artworks or other building decorations
not comparable to any existing decorations. Landlord shall not collect more than
100% of Operating Expenses and shall not recover any item of cost more than
once. As used in this Section 8.5, “Prime Rate” shall mean the highest prime
rate of interest published in the “Money Rates” column in The Wall Street
JOURNAL during such calendar month. If The Wall Street Journal ceases
publication of a prime rate, then the Prime Rate shall mean the highest prime
rate of interest publicly announced during such month by Bank of America, N.A.,
or its successor (or if such bank ceases to exist then any national banking
association selected by Landlord).

          8.6 Taxes on Rent. The Rent provided for in this Lease is exclusive
of any sales or other tax or charge upon, based upon or measured by rents
payable to Landlord hereunder, or any tax or other charge based upon or measured
by the number of employees of Tenant, or any other tax that is not currently in
effect. If during the Term any such tax or other charge becomes payable by
Landlord to any governmental authority, the Rent hereunder shall be deemed
increased by such amount upon thirty (30) days written notice by Landlord to
Tenant. The foregoing does not apply to federal, state or local income, gross
receipts, inheritance, gift, succession or franchise taxes payable by Landlord.

SECURITIES AND EXCHANGE COMMISSION.]

          8.7 Audit. Provided that Tenant is not in default under this Lease
and pays any Operating Expenses billed by Landlord as and when due, Tenant or a
qualified certified public accountant retained by Tenant who is experienced with
accounting for operating expense recoveries in commercial leases, shall have the
right to examine Landlord’s books and records relating to Operating Expenses
upon reasonable prior notice given within ninety (90) days after receipt of
Landlord’s annual reconciliation, during normal business hours at the place or
places where such records are normally kept. Tenant’s representative shall be
compensated on an hourly or project basis and not on (i) a contingent basis,
(ii) the basis of a percentage of any savings or refund resulting from the
audit, or (iii) in any other manner that makes such representative’s
compensation for such audit in any way dependent on the results of the audit.
Upon request, Tenant shall provide Landlord with a full copy of all
correspondence, instructions between the accountant. Landlord’s calculation
shall be final and binding on Tenant upon delivery thereof, except as to matters
to which written objection is made by Tenant in accordance with this Section.
Tenant may dispute specific items included in Operating Expenses or Landlord’s
computation of Tenant’s Share of Operating Expenses, by sending notice
specifying such objections and including support for such findings with specific
reference to the relevant Lease provisions disqualifying such expenses to
Landlord no later than one hundred and twenty (120) days after Tenant’s
representative examines such records. If Landlord agrees with Tenant’s
objections, appropriate rebates or charges shall be made to Tenant within a
reasonable period of time thereafter. The results of any review of Operating
Expenses hereunder shall be treated by Tenant, its accountant and each of their
respective employees and agents as confidential, and shall not be discussed with
nor disclosed to any third party. If Tenant objects to any matters as provided
above, Landlord shall refer the matter to an independent certified public
accountant selected by Landlord, whose certification as to the proper amount
shall be final and binding on Landlord and Tenant. Tenant shall promptly pay the
cost of such certification and all other costs incurred by Tenant to examine
Landlord’s books and records. Pending resolution of any such exceptions in the
foregoing manner, Tenant shall continue paying Tenant’s Share of Operating
Expenses in the amounts determined by Landlord, subject to adjustment upon
resolution of any objections by Tenant. If the certification determines that
Landlord overstated Tenant’s Share of Operating Expenses, then Tenant shall
receive a credit for the amount of such overpayment against the next
installment(s) of Operating Expenses; provided, however, that if the Term has
expired Landlord shall pay Tenant the excess within thirty (30) days after the
certification is finalized. If the certification determines that Landlord
understated Tenant’s Share of Operating Expenses, then Tenant shall pay such sum
due with its next monthly installment of Rent. Landlord shall have the same
rights with respect to Tenant’s nonpayment of Operating Expenses as it has with
respect to any other nonpayment of Rent under this Lease.

     9. Landlord’s Maintenance and Services Obligations.

          9.1 Maintenance Obligations. Except as otherwise provided in Section
7.4, Landlord shall be responsible for maintenance and repairs to the exterior
(including the exterior glazing and caulking) and structural portions of the
Building, the roof and roof membrane, as well as all building systems and
components not exclusively serving the Premises and repairs and maintenance to
the Common Areas (“Maintenance Obligations”).

DOCUMENT. EACH SUCH PORTION, WHICH HAS BEEN OMITTED HEREIN AND REPLACED WITH A
SERIES OF THREE ASTERISKS IN BRACKETS [***], HAS BEEN FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION.]

          9.2 Services Obligations. Except as provided herein, Landlord shall
provide or cause to be provided, all services to the Premises, Building and
Property, including without limitation, janitorial service for common areas,
garbage and recycling programs, property management, landscape and irrigation
system maintenance, parking lot sweeping and maintenance, window washing,
rubbish removal, a preventative maintenance program for the heating,
ventilating, and air conditioning systems not exclusively serving the Premises,
and other services provided by Landlord (collectively “Services Obligations”).

          9.3 Specialized Equipment. During any period in which any other
Building occupant has the right to the use or benefit of such equipment,
Landlord shall be responsible for repair and maintenance of the equipment
located in the following areas within the Premises, as shown on Exhibit A (the
“Specialized Equipment”): (a) boiler room for 50-150 PSI steam, (b) de-ionized
water, (c) compressed air and vacuum pump, and (d) mechanical/electrical room.
All of the Specialized Equipment is located in the Premises and Landlord
reserves from the Lease the right to access the Specialized Equipment as and
when necessary to perform its obligations hereunder. All costs relating to the
Specialized Equipment shall be paid by the Building occupants that have the
right to the use or benefit of the Specialized Equipment and Landlord shall not
be required to bear any costs relating to the Specialized Equipment. At any time
when Tenant is the only party who has the right to the use or benefit of the
Specialized Equipment, Tenant shall be responsible, at Tenant’s cost, for all
repair and maintenance thereof, in accordance with standards acceptable to
Landlord in its reasonable discretion.

          9.4 No Landlord Default. Landlord shall perform the Maintenance and
Service Obligations diligently and promptly as circumstances warrant, but
Landlord shall not be liable for any failure to perform the Maintenance and
Services Obligations unless such failure is solely due to Landlord’s gross
negligence or intentional misconduct and continues for an unreasonable period of
time after written notice from Tenant. In no event shall Landlord be liable to
Tenant under this Lease or otherwise for any incidental, consequential or
punitive damages (including but not limited to lost profits) and Tenant waives
any right to claim such damages. If the need for repair results from the
business activity being conducted within the Premises, or from the acts or
omissions of Tenant, its officers, directors, employees, agents, contractors or
invitees, Tenant shall reimburse Landlord for the costs incurred by Landlord in
connection with such repair. Landlord shall have no liability for any damage or
injury arising out of any condition or occurrence causing a need for repairs,
unless the damage or injury was caused solely by Landlord’s gross negligence.

          9.5 No Obligation to Alter. Except as specifically provided
elsewhere in this Lease, Landlord shall have no obligation whatsoever to after,
remodel, improve, repair, decorate, or paint the Building, the Premises or any
part thereof. Tenant affirms that Landlord has made no representations to Tenant
about the condition of the Premises or the Building, except as specifically
herein set forth.

          9.6 Tenant Waiver. Tenant waives the right to make repairs at
Landlord’s expense under any law, statute, or ordinance now or hereafter in
effect.

     10. Structural Maintenance and Repairs.

          10.1 Structural Repairs. Subject to the provisions of Section 15,
Landlord shall, at Landlord’s expense, maintain, repair and replace the roof
structure, all exterior and bearing walls, the floor slab and the foundation of
the Building (“Structural Repairs”). Landlord shall give reasonable advance
notice to Tenant of such repairs to the extent practical and feasible.

          10.2 Utilities Repairs. Subject to the provisions of Section 15,
Landlord shall maintain, repair and replace the underground electrical, water,
sewer and plumbing utility systems serving the Building insofar as such utility
systems are located outside the Building between the public right-of-way and the
Building or inside the Building but not serving the Premises exclusively, and
the conduits and pipes or wiring located therein and forming a part thereof, or
Landlord shall cause the utility purveyor to maintain, repair and replace the
underground electrical, water, sewer and plumbing utility systems serving the
Building insofar as such utility systems are located outside the Building
between the public right-of-way and the Building, and the conduits and pipes or
wiring located therein and forming a part thereof (“Utility Systems Repairs”).

          10.3 Tenant’s Responsibility. To the extent that any Structural
Repairs or Utility Systems Repairs are necessitated in part or in whole by the
act, neglect, fault, or omission of any duty by the Tenant, its agents,
contractors, servants, or employees, Tenant shall pay to Landlord the reasonable
costs of such Structural Repairs or Utility Systems Repairs, within thirty (30)
days after Landlord’s submission of a reasonably detailed invoice for the same.
Landlord shall not be liable for any failure to make any Structural Repairs or
Utility Systems Repairs, unless such failure shall persist for an unreasonable
time after Landlord’s receipt of written notice from Tenant.

     11. Utilities.

          11.1 Tenant Responsibility. In addition to all other sums Tenant is
required to pay pursuant to this Lease, Tenant shall be solely responsible for
and shall pay as additional rent prior to delinquency all charges for heat,
light, water, sewer, electricity, gas and any other utilities used or consumed
on the Premises from and after the date Tenant first takes possession of the
Premises. For any of the foregoing utilities for which separate meters are
provided by the utility service company, Tenant shall arrange for and cause such
services to be provided, at Tenant’s expense and Tenant shall pay directly to
the provider thereof and will pay any required deposits therefor. For any of the
foregoing utilities and services for which separate meters are not installed,
Landlord shall arrange for such service and either (a) the cost shall be
included in Operating Expenses, or, (b) if Landlord reasonably determines based
on demonstrable evidence that the amount of service or utility provided by
Landlord (including use of the Specialized Equipment) and consumed by Tenant is
materially different than Tenant’s Share of such utility or service, then Tenant
shall pay to Landlord as Additional Rent, prior to delinquency, Tenant’s
equitable share of the cost of such utility or service based on Landlord’s
reasonable estimates of Tenant’s consumption (which may be based on submeter
readings if Landlord installs submeters to measure consumption). Tenant shall
arrange for and cause the following services to be provided to the Premises at
Tenant’s expense: telecommunications

and data communications services, security, telephone service, cable television
service, satellite transmission service, if any, and any computer cabling or
wiring exclusively serving the Premises.

          11.2 Interruption. If any utilities to the Premises are interrupted
or discontinued due to failure in those portions of the systems to be maintained
by Landlord pursuant to Section 10.2, Landlord shall use reasonable efforts to
restore such utilities as soon as practically possible after learning of such
interruption or discontinuance. No eviction of Tenant shall result from any such
failure or interruption. Notwithstanding the foregoing, if an interruption or
curtailment of any service required to be provided by Landlord under this Lease
occurs (A) by reason of Landlord’s negligent act or negligent omission or due to
a cause for which Landlord receives rent abatement insurance proceeds, (B) such
interruption causes the Premises or a portion thereof to be untenantable, (C)
Tenant ceases to use the Premises or the untenantable portion thereof for their
intended purposes, and (D) Tenant has given Landlord notice of such interruption
and such interruption is not corrected within three (3) days after the date of
such notice, then, as Tenant’s exclusive remedy for such interruption on the
fourth (4th) consecutive day following the date on which all of the foregoing
conditions are satisfied, Base Monthly Rent shall abate (in whole or in part
based on the number of square feet that are untenantable) until the Premises are
rendered tenantable. Notwithstanding the foregoing, Tenant shall not be entitled
to an abatement if the interruption was caused by the negligent act or negligent
omission of Tenant or its employees, agents, contractors or invitees.

     12. Limits on Landlord’s Liability. Landlord’s liability to repair and
maintain portions of the Premises and Building and to provide utility services
(collectively, “Repair and Service Obligations”) is subject to the following
limitations:

          12.1 Circumstances Beyond Landlord’s Control. Landlord shall not be
liable for any failure of Repair and Service Obligations when such failure is
caused by (i) strikes, lockouts or other labor disturbance or labor dispute of
any character, (ii) governmental regulation, moratorium or other governmental
action, (iii) inability despite the exercise of reasonable diligence to obtain
electricity, water, fuel or other utilities from the providers thereof, (iv)
acts of God, or (v) any other cause beyond Landlord’s reasonable control.

          12.2 Landlord Liability. Landlord shall not be liable for any
failure of Repair and Service Obligations, unless such failure shall persist for
an unreasonable time after written notice of the need of such repairs or
maintenance or of the interruption of services is given to Landlord by Tenant.
Landlord shall not be liable for any injury to or interference with Tenant’s
business arising from the making of any repairs, alterations, or improvements in
or to any portion of the Building, the Premises, or the Property, or to
fixtures, appurtenances, and equipment therein. Landlord shall not have any
liability for any inconvenience, annoyance, or disturbance resulting from the
performance by Landlord of its Repair and Service Obligations. Without limiting
the generality of this Section 12, in no event shall Landlord have any liability
for consequential damages resulting from any act or omission of Landlord in
respect of its Repair and Service Obligations, even if Landlord has been advised
of the possibility of such consequential damages. Landlord, its agents,
employees or contractors, shall conduct its and their activities on the Premises
in a reasonable manner and shall make reasonable efforts to minimize any
inconvenience, annoyance or disturbance to Tenant and shall repair any

uninsured physical damage caused in doing such repair work. At Tenant’s request,
Landlord shall perform its Repair and Service Obligations after Tenant’s normal
business hours; provided, however, that Tenant shall pay all overtime and other
costs incurred by Landlord in excess of the costs that would have been incurred
by Landlord if Landlord had performed its Repair and Service Obligations during
Tenant’s normal business hours.

          12.3 Rent Abatement. Except as specifically provided in Sections
1,11, 15 and 16, there shall be no abatement of Rent in any circumstance under
this Lease.

     13. Improvements and Alterations.

          13.1 Initial Tenant Improvements. Tenant, at Tenant’s sole cost and
expense, shall install its initial tenant improvements in the Premises in
accordance with the provisions of Exhibit B attached hereto and incorporated
herein by this reference.

          13.2 Alterations and Additions by Tenant. Following installation of
the initial tenant improvements, Tenant shall not make any additional
improvements or alterations to the Premises without the prior written consent of
Landlord which, with respect to any alterations that do not impact Building
systems or structure or reduce the value of the Building or reduce the RSF of
the laboratory space, shall not be unreasonably withheld or delayed but may be
subject to such reasonable conditions as Landlord deems necessary or desirable.
Any repairs or new construction by Tenant shall be done (a) at Tenant’s sole
cost and expense in conformity with plans and specifications approved by
Landlord which approval shall not be unreasonably withheld (so long as the
changes do not impact Building systems or structure) or delayed but may be
subject to such reasonable conditions as Landlord deems necessary or desirable,
(b) by contractors approved by Landlord which shall not be unreasonably withheld
or delayed but may be subject to such reasonable conditions as Landlord deems
necessary or desirable, and (c) subject to Landlord’s reasonable rules and
regulations regarding such construction. All work performed shall be done
lien-free in a good and workmanlike manner consistent with the overall quality
of the Building and shall become the property of Landlord. Prior to commencing
any work costing more than Fifty Thousand Dollars ($50,000) or the supply or
furnishing of any labor, services and/or materials in connection with any such
work, Landlord may require that Tenant provide to Landlord, at Tenant’s expense,
a lien and completion bond in an amount equal to 120% of the estimated cost of
any improvements, additions, or alterations in the Premises.

     14. Insurance; Indemnity.

          14.1 Tenant Waiver. Except as provided in Section 14.3, Landlord
shall not be liable to Tenant, and Tenant hereby waives all claims against
Landlord, for injury or damage to any person or property in or about the
Premises, Building, Property or common areas by or from any cause whatsoever,
including without limitation any acts or omissions of Landlord, Landlord’s
property manager or any other tenants, licensees or invitees of the Building.

          14.2 Tenant Indemnity. Tenant shall indemnify and defend (using
legal counsel reasonably acceptable to Landlord) Landlord and hold Landlord
harmless, from and against any and all loss, cost, damage, liability and expense
(including reasonable attorneys’

[*CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS

fees) whatsoever that may arise out of or in connection with Tenant’s
occupation, use or improvement of the Premises, or that of its employees, agents
or contractors, or Tenant’s breach of its obligations under this Lease. To the
extent necessary to fully indemnify Landlord from claims made by Tenant or its
employees, this indemnity constitutes a waiver of Tenant’s immunity under the
Washington Industrial Insurance Act, RCW Title 51. This indemnity shall survive
the expiration or termination of the Term.

          14.3 Landlord Responsibility. The exculpation, release and indemnity
provisions of Sections 14.1 and 14.2 shall not apply if the subject claims
thereunder were caused solely by Landlord’s gross negligence or willful
misconduct. However, in no event shall Landlord be liable to Tenant for
consequential damages. Landlord shall indemnify and defend (using legal counsel
reasonably acceptable to Tenant) Tenant and hold Tenant harmless, from and
against any and all loss, cost, damage, liability and expense (including
reasonable attorneys’ fees) whatsoever to the extent arising solely out of the
gross negligence or intentional misconduct of Landlord. To the extent necessary
to fully indemnify Tenant from claims made by Landlord or its employees, this
indemnity constitutes a waiver of Landlord’s immunity under the Washington
Industrial Insurance Act, RCW Title 51. This indemnity shall survive the
expiration or termination of the Term.

          14.4 Tenant’s Insurance. Tenant shall procure and maintain
throughout the Term at Tenant’s expense, the following insurance:

               14.4.1 Commercial general liability insurance, insuring Tenant
against liability arising out of the Lease and the use, occupancy, or
maintenance of the Premises and all areas appurtenant thereto. Such insurance
shall be in the amount of not less than $5,000,000 combined single limit for
injury to or death of one or more persons in an occurrence, and for damage to
tangible property (including loss of use) in an occurrence (or in such amount as
Landlord determines in its reasonable discretion). Such policy shall include
Products/Completed Operations coverage with an aggregate limit of no less than
$2,000,000. Such policy shall insure Tenant’s contractual liability (covering
the indemnity in Section 14.2) and shall: (i) name Landlord and its named
principals, property manager and lender as additional insureds, (ii) provide a
waiver of subrogation with respect to Landlord, and (iii) provide that it is
primary and noncontributing with any insurance in force on behalf of Landlord.

               14.4.2 “Causes of Loss — Special Form” property insurance (or
comparable coverage acceptable to Landlord) insuring against the perils of fire,
vandalism and malicious mischief and including extended coverage and coverage
against sprinkler leakage. This insurance policy shall be upon all personal
property for which Tenant is legally liable or that was installed at Tenant’s
expense, and that is located in the Building or Premises, including without
limitation all of Tenant’s furnishings, fixtures, furniture, personal property
and equipment and all tenant improvements and alterations installed in the
Premises at Tenant’s expense in an amount not less than the full replacement
cost thereof on an agreed amount basis with no coinsurance. Tenant has been
advised that it may be desirable to purchase insurance against risk of loss by
earthquake provided that such insurance is available on commercially reasonable
terms. Tenant’s property insurance policy(ies) shall name Landlord and any
mortgagees of Landlord as insured parties, as their respective interests may
appear. Tenant acknowledges that Landlord has recommended that Tenant purchase
business interruption coverage, covering

direct or indirect loss of Tenant’s earnings attributable to Tenant’s inability
to use fully or obtain access to the Premises or Building. Tenant may elect to
purchase such insurance but in any event waives any claim against Landlord from
any cause of loss that would be covered by insurance had Tenant purchased such
coverage.

               14.4.3 Worker’s Compensation and Employees Liability Insurance
as required by state law.

               14.4.4 Any other form or amount of insurance as Tenant or
Landlord or any mortgagees of Landlord may reasonably require from time to time
in form, in amounts and for insurance risks against which a prudent tenant would
protect itself. As used in this paragraph, insurance shall be deemed to be
reasonable if it is of the type and in such amounts as commercial landlords
require in leases in the market area in which the premises are located for
premises used for the uses similar to Tenant’s.

          14.5 Policies. All policies of insurance to be obtained by Tenant
hereunder shall be in a form satisfactory to Landlord and shall be issued by
insurance companies holding a General Policyholder Rating of “A” and a Financial
Rating of “X” or better in the most current issue of Best’s Insurance Guide.
Tenant shall provide Landlord with certificates of such insurance on certificate
forms acceptable to Landlord. No such policy shall be cancelable or reduced in
coverage below that required under this Lease except after thirty (30) days
prior written notice to Landlord. Tenant shall, within ten (10) days prior to
the expiration of such policies, furnish Landlord with renewals or “binders”
thereof, or, if Tenant has not done so, Landlord may order such insurance and
charge the cost thereof to Tenant as Additional Rent.

          14.6 Landlord’s Insurance. Landlord shall procure and maintain
throughout the Term commercial general liability insurance with deductibles
deemed appropriate by Landlord. Landlord shall also shall procure and maintain
throughout the Term “Causes of Loss — Special Form” (or comparable) property
insurance insuring against the perils of fire, vandalism and malicious mischief,
and including extended coverage, covering the Building and all permanent
fixtures and improvements therein on the Commencement Date in an amount not less
than the full replacement cost thereof. Landlord may purchase insurance against
risk of loss by earthquake provided that such insurance is available on
commercially reasonable terms. Landlord shall also shall procure and maintain
throughout the Term rent loss insurance in an amount equal to twelve (12) months
Base Monthly Rent and Additional Rent. Landlord may also purchase any other
amount or type of coverage Landlord (or its lender) deems necessary or desirable
including coverage against terrorism or vandalism. The cost of all insurance
purchased by Landlord and any related deductibles shall be an Operating Expense.

          14.7 Proceeds. The proceeds of any insurance policies maintained by
or for the benefit of Landlord shall belong to and be paid over to Landlord. Any
interest or right of Tenant in any such proceeds shall be subject to Landlord’s
interest and right in such proceeds. The proceeds of any insurance policies
maintained by or for the benefit of Tenant shall belong to and be paid over to
Tenant; provided, however, that if Landlord is required to, or elects to,
restore the Premises or the Building pursuant to Section 15, then the proceeds
of any property insurance covering permanent improvements to the Premises shall
be paid over to Landlord.

SERIES OF THREE ASTERISKS IN BRACKETS [***], HAS BEEN FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION.]

          14.8 Waiver of Subrogation. Landlord and Tenant release each other,
and their respective directors, officers, partners, employees and agents, from,
and waive their entire claim of recovery for, any claims for damage to the
Premises and the Building and to Tenant’s improvements, alterations, furniture,
fixtures, equipment and personal property that are caused by or result from
fire, lightening or any other perils normally included in a “Causes of Loss -
Special Form” property insurance policy whether or not such loss or damage is
due to the negligence of Landlord, its directors, officers, partners, employees
or agents, or of Tenant, or its directors, officers, partners, employees or
agents. Landlord and Tenant shall cause each insurance policy obtained by it to
provide that the insurance company waives all right of recovery by way of
subrogation against either party in connection with any damage covered by any
and all insurance policies maintained by either Landlord or Tenant under this
Lease.

          14.9 Notice of Accidents. Tenant shall promptly notify Landlord of
any casualty or accident occurring in or about the Premises.

     15. Destruction.

          15.1 Obligation to Restore. If the Premises or the Building is
destroyed or damaged by fire, earthquake, or other casualty during the Term to
the extent that they are untenantable in whole or in part, and if (i) the
insurance proceeds available to Landlord equal or exceed the cost of such
restoration, (ii) in the opinion of a registered architect or engineer appointed
by Landlord and given within ninety (90) days of the casualty, such restoration
can be completed within one hundred eighty (180) days after the date on which
Landlord obtains all permits necessary for such restoration, and (iii) such
restoration is permitted under then existing laws and the CC&Rs to be done in
such a manner as to return the Premises (including only those fixtures and
equipment insured under Landlord’s property insurance policy) and the Building
to substantially the same condition as they were in immediately before such
destruction then such destruction shall not terminate this Lease and Landlord
shall act with reasonable diligence to restore the Premises and the Building to
substantially the same condition as they were in immediately before such
destruction. To the extent that the insurance proceeds must be paid to a
mortgagee under, or must be applied to reduce any debt secured by, a mortgage
covering the Property, the insurance proceeds shall be deemed not to be
available to Landlord unless such mortgagee permits Landlord to use the
insurance proceeds for such restoration. In all other instances, Landlord shall
have the right but not the obligation to rebuild and restore the Premises or the
Building or the damaged part thereof.

          15.2 Right to Terminate. If the Premises or the Building is
destroyed or damaged by fire, earthquake, or other casualty during the Term to
the extent that they are untenantable in whole or in part, and Landlord is not
obligated under Section 15.1 to restore the Premises and the Building then
Landlord may, at its election, either (i) restore the Premises (including only
those fixtures and equipment insured under Landlord’s property insurance policy)
and the Building to substantially the same condition as they were in immediately
before such destruction, or (ii) terminate this Lease effective as of the date
of such destruction. As soon as reasonably practicable after the date of any
destruction or injury, Landlord shall notify Tenant whether Landlord intends to
restore the Premises or terminate this Lease.

22

 

[*CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS
DOCUMENT. EACH SUCH PORTION, WHICH HAS BEEN OMITTED HEREIN AND REPLACED WITH A
SERIES OF THREE ASTERISKS IN BRACKETS [***], HAS BEEN FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION.]

     If the Premises or the Building is destroyed or damaged by fire,
earthquake, or other casualty during the Term to the extent that they are
untenantable in whole or in part, and Landlord is obligated to or elects to
restore the Premises and the Building and such restoration is not completed
within two hundred forty (240) days (as extended by any delay caused by force
majeure events) after the date on which Landlord obtains all permits necessary
for such restoration, then either Landlord or Tenant may, at its election within
sixty (60) days after the expiration of such period, terminate this Lease by
written notice to the other party. If neither party makes an election under the
preceding sentence, then the parties shall be deemed to have elected to continue
this Lease and the parties’ right to terminate this Lease shall be void and of
no further force or effect. If casualty occurs during the last twelve (12)
months of the Term, Tenant or Landlord may terminate this Lease by written
notice to the other party at any time prior to the start of reconstruction.

          15.3 Rent Abatement. During the period from destruction or damage
until completion of restoration (or termination of this Lease), Rent shall be
abated in the same ratio as that portion of the Premises which the parties
reasonably determine is unfit for occupancy shall bear to the whole Premises. If
damage is due to the fault or neglect of Tenant or its agents, employees,
invitees, or licensees, there shall be no abatement of Rent except to the extent
Landlord actually recovers lost rent under its rental insurance policy and
Tenant shall have no right to terminate this Lease as a result of such damage.

          15.4 Restoration of Tenant Improvements. Landlord shall not be
required to repair any injury or damage by fire or other cause, or to make any
repairs or replacements of any of Tenant’s personal property, furniture,
equipment or tenant improvements installed by Tenant (all of which Tenant is
required to insure). Instead, if Landlord repairs or rebuilds the Premises under
this Section 15, Tenant shall repair, rebuild or replace all such tenant
improvements and other items of property to substantially the same condition as
they were in immediately before such destruction or damage. If Tenant is not
required to restore such items then the proceeds of Tenant’s property insurance
shall belong to and be paid over to Tenant.

          15.5 No Liability. Tenant shall not be entitled to any compensation
or damages from Landlord for loss of the use of the whole or any part of the
Premises, the property of Tenant, or any inconvenience or annoyance occasioned
by such damage, repair, reconstruction, or restoration, except for the rent
abatement provided in Section 15.3 above.

     16. Condemnation.

          16.1 Total Taking. If all or part of the Premises are taken under
power of eminent domain, or sold under the threat of the exercise of said power,
this Lease shall terminate as to the part so taken as of the date the condemning
authority takes possession.

          16.2 Partial Taking. If more than twenty-five percent (25%) of the
floor area of Premises is taken by condemnation or sold under the threat of the
exercise of said power or if the taking means the Premises are no longer
suitable for Tenant’s operations, Landlord or Tenant may, by written notice
given to the other within ten (10) Business Days after notice of such taking,
terminate this Lease as to the reminder of the Premises as of the date the
condemning authority takes possession.

[*CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS
DOCUMENT. EACH SUCH PORTION, WHICH HAS BEEN OMITTED HEREIN AND REPLACED WITH A
SERIES OF THREE ASTERISKS IN BRACKETS [***], HAS BEEN FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION.]

          16.3 Rent Abatement. If Landlord or Tenant does not so terminate,
this Lease shall remain in effect as to such remainder, except that the Rent
shall be reduced in the proportion that the rentable floor area taken bears to
the original rentable total floor area. If neither Landlord nor Tenant elects to
terminate this Lease, Landlord’s responsibility to restore the remainder of the
Premises shall be limited to the amount of any condemnation award allocable to
the Premises, as determined by Landlord.

          16.4 Award. Tenant may not participate or appear in the condemnation
proceeding. Any award for the taking of all or part of the Premises under the
power of eminent domain, including payment made under threat of the exercise of
such power, shall be the property of Landlord, whether made as compensation for
diminution in value of the leasehold or for the taking of the fee or as
severance damages. Landlord shall have the sole right to grant early possession
and use to the condemning authority prior to trial. Tenant waives any right to
claim from Landlord or from the condemning authority any compensation for the
value of the leasehold and Landlord shall be entitled to the entire award for
the Premises, the Building and the Property and Tenant assigns any right it
might have in such award to Landlord. Tenant shall not seek any recovery for the
value of the leasehold nor shall it seek to introduce evidence as to the value
of such leasehold in the condemnation action or in any equitable proceeding to
allocate the condemnation award between the parties. Notwithstanding the
foregoing, so long as Tenant does not violate any of its covenants under this
Section and subject to the rights of Landlord’s lender, Tenant shall be entitled
to recover such compensation as may be separately awarded or recoverable by
Tenant in Tenant’s own right in a separate action for Tenant’s moving expenses.
Landlord shall not be liable to Tenant for the loss of the use of all or any
part of the Premises taken by condemnation.

          16.5 Exclusive Control. Landlord shall have the exclusive authority
to grant possession and use to the condemning authority and to negotiate and
settle all issues of just compensation or, in the alternative, to conduct
litigation concerning such issues; provided, however, that Landlord shall not
enter into any settlement of any separate award that may be made to Tenant as
described in Section 16.4 without Tenant’s prior approval of such settlement,
which approval shall not be unreasonably withheld.

     17. Assignment and Subletting.

          17.1 Consent Required. Tenant shall not assign this Lease, or sublet
the Premises or any part thereof, either by operation of law or otherwise, or
permit any other party to occupy all or any part of the Premises (each of which
is referred to herein as a “Transfer”), without first obtaining the written
consent of Landlord which shall not be unreasonably withheld or delayed provided
that Tenant satisfies all of the conditions of this Lease. Tenant may not enter
into a Transfer at any time when Tenant is in default hereunder. This Lease
shall not be assignable by operation of law. If Tenant intends to enter into a
Transfer, Tenant shall give Landlord at least thirty (30) days written notice of
such intent. Tenant’s notice shall set forth the effective date of such Transfer
and shall be accompanied by (i) an exact copy of the proposed agreements between
Tenant and the proposed transferee, (ii) complete financial information
regarding the proposed transferee, and (iii) a description of the transferee’s
contemplated use of the Premises. If requested by Landlord, Tenant shall provide
Landlord with (a) any additional information or documents reasonably requested
by Landlord relating to the proposed Transfer

24

 

[*CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS

SECURITIES AND EXCHANGE COMMISSION.]

or the transferee, and (b) an opportunity to meet and interview the proposed
transferee. Any Transfer without Landlord’s consent shall be a default hereunder
and, in addition to any other right or remedies permitted hereunder shall be
voidable by Landlord, at its sole election.

          17.2 Corporate Transfers. All of the following shall constitute
Transfers subject to this Article 17: (x) if Tenant is a corporation that is not
publicly traded on a nationally recognized reputable stock exchange, then any
transfer of this Lease by merger, consolidation or liquidation, or any direct,
indirect or cumulative change in the ownership of, or power to vote the majority
of Tenant’s outstanding voting stock, shall constitute a Transfer; (y) if Tenant
is a partnership, then a change in general partners in, or voting or
decision-making control of, the partnership shall constitute a Transfer; and (z)
if Tenant is a limited liability company, then a change in voting or
decision-making control of the limited liability company shall constitute a
Transfer. Any change in ownership of Tenant’s parent of the type described in
(x), (y) or (z) above shall also constitute a Transfer subject to this Article
17. These provisions shall apply to any single transaction or any series of
related or unrelated transactions having the effect described.

          17.3 Permitted Transfers. Notwithstanding anything herein to the
contrary, provided Tenant is not in default under this Lease at the time of such
transaction, Landlord’s consent under Section 17.1 or otherwise shall not be
required for, and the provisions of Section 17.6 relating to division of excess
rent between Landlord and Tenant shall not apply to, any proposed Transfer by
Tenant under this Section 17 to any of the following (each of whom shall be a
“Permitted Transferee”): (a) a wholly owned subsidiary of Tenant; (b) an entity
with which or into which Tenant may merge whether or not the Tenant is the
survivor of such merger; (c) any entity that is controlled by, controls or is
under common control with Tenant; (d) any entity that acquires substantially all
of Tenant’s assets; or (e) any entity into which Tenant consolidates; provided,
however, that any Permitted Transferee under this provision must have and
maintain a Net Worth equal to or better than the Net Worth of Tenant at the time
of execution of this Lease. “Control” for purposes of this Section 17 shall mean
ownership of a majority voting interest in any such entity or the possession,
directly or indirectly of the power to direct or cause the direction of the
day-to-day management of the controlled entity. “Net Worth” shall mean Tenant’s
aggregate tangible assets (which shall not include goodwill, patents,
intellectual property rights or trademarks or trade names) minus Tenant’s
aggregate liabilities. Tenant must provide Landlord with at least thirty (30)
days prior written notice of any Transfer to a Permitted Transferee, together
with such evidence as Landlord may reasonably request to establish that such
Transfer is to a Permitted Transferee. The rights under this Section are
personal to the Tenant named herein and may not be transferred or assigned to
any other party other than a Permitted Transferee. A series of transfers to
Permitted Transferees may not be used to evade the requirement for Landlord’s
consent under this Section 17.

          17.4 Recapture. Intentionally omitted.

          17.5 Consent. In deciding whether to consent to a proposed Transfer
that requires Landlord’s consent, Landlord may consider any factors that
Landlord deems relevant, including but not limited to the following: (i) whether
the use of the Premises by the proposed transferee would be a permitted use;
(ii) whether the proposed transferee is of sound financial condition and has
sufficient financial resources and business expertise, as reasonably

determined by Landlord, to perform under this Lease; (iii) whether the proposed
transferee’s use could involve the storage, use, treatment or disposal of any
Hazardous Materials not used by Tenant or in greater quantities than Tenant
uses; and (iv) whether the proposed use or the proposed transferee could cause
the violation of any covenant or agreement of Landlord to any third party.
Landlord may condition its consent to any proposed Transfer on such reasonable
conditions as Landlord may require including construction of any improvements
reasonably deemed necessary or appropriate by Landlord by reason of the
Transfer. Any improvements, additions, or alterations to the Building that are
required by any law, ordinance, rule or regulation, or are reasonably deemed
necessary or appropriate by Landlord as a result of any Transfer hereunder,
shall be installed and provided by Tenant without cost or expense to Landlord.
Failure by Landlord to approve a proposed Transfer shall not cause a termination
of this Lease, and the sole remedy of Tenant shall be an action for injunctive
or declaratory relief.

          17.6 Minimum Rental; Division of Excess Rent. In any Transfer of
this Lease (other than a Transfer to a Permitted Transferee), Tenant shall seek
to obtain from the transferee consideration reflecting the then-current fair
market rent for the space subject to such Transfer. Any net rent or other
consideration attributable to the Premises realized by Tenant in connection with
or as a result of any Transfer (other than a Transfer to a Permitted Transferee)
in excess of the Base Monthly Rent payable hereunder, after first deducting all
reasonable and customary costs actually incurred by Tenant to effect such
Transfer (such as tenant improvements, brokerage fees, advertising costs and the
like) shall be divided equally between Landlord and Tenant and Landlord’s share
shall be paid promptly to Landlord as Additional Rent; provided, however, that
Landlord shall be entitled to receive the total rent and other consideration if
a default (after any required notice and expiration of any applicable cure
period) is outstanding under this Lease until such default is cured.

          17.7 Tenant Not Released. No Transfer by Tenant (including a
Transfer to a Permitted Transferee) shall relieve Tenant of any obligation under
this Lease and Tenant shall remain primarily liable hereunder. If the transferee
defaults, Landlord may, without affecting any other rights of Landlord, proceed
against Tenant or any transferee or any other person liable for Tenant’s
obligations hereunder. Any Transfer that conflicts with the provisions hereof
shall be void. No consent by Landlord to any Transfer shall constitute a consent
to any other Transfer nor shall it constitute a waiver of any of the provisions
of this Article 17 as they apply to any future Transfers. Following any
Transfer, the obligations for which the Tenant or subsequent transferor remains
liable under this Lease shall include, without limitation, any obligations
arising in connection with any amendments to this Lease executed by Landlord and
the transferee, whether or not such amendments are made with knowledge or
consent of the transferor; provided, however, that Landlord shall not extend the
term of the Lease (except in connection with the Extension Option granted
herein) without Tenant’s consent.

          17.8 Written Agreement. Any Transfer must be in writing. With
respect to any assignment, the transferee shall assume in writing, for the
express benefit of Landlord, all of the obligations of Tenant under this Lease,
provided that no such assumption shall be deemed a novation or other release of
the transferor. With respect to any sublease, the subtenant shall agree in
writing to comply with all of the obligations of Tenant under this Lease with
respect to the use or occupancy of the space transferred and all insurance and
indemnity provisions provided that no such agreement shall be deemed a novation
or other release of the transferor.

SERIES OF THREE ASTERISKS IN BRACKETS [***], HAS BEEN FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION.]

If this Lease is terminated, Landlord, at its option, may elect to either (a)
terminate any or all existing subleases or (b) have such termination operate as
an assignment to Landlord of any or all existing subleases. Tenant shall provide
to Landlord true and correct copies of the executed Transfer documents and any
amendment thereto during the Term.

          17.9 Expenses. Landlord may hire outside consultants to review the
Transfer documents and information. Tenant shall reimburse Landlord for all
reasonable out-of-pocket costs and expenses incurred by Landlord in connection
with any request for consent under this Section 17 (even if consent is denied or
the request is withdrawn) and such reimbursement shall include reasonable
attorneys’ fees, on demand.

          17.10 No Restriction on Landlord. Without liability to Tenant,
Landlord shall have the right to offer and to lease space to any party,
including without limitation parties with whom Tenant is negotiating, or with
whom Tenant desires to negotiate, a Transfer.

          17.11 No Leasehold Financing. Tenant shall not encumber, pledge or
mortgage the whole or any part of the Premises or any fixtures or improvements
in the Premises, or this Lease, nor shall this Lease or any interest thereunder
be assignable or transferable by operation of law or by any process or
proceeding of any court or otherwise without the prior written consent of
Landlord, which consent may be given or withheld in Landlord’s sole discretion.

          17.12 Bankruptcy. If this Lease is assigned pursuant to the
provisions of the Revised Bankruptcy Act, 11 U.S.C. Section 101, et seq., any
and all consideration paid or payable in connection with such assignment shall
be Landlord’s exclusive property and paid or delivered to Landlord, and shall
not constitute the property of Tenant or Tenant’s estate in bankruptcy. Any
person or entity to whom the Lease is assigned pursuant to the Revised
Bankruptcy Act shall be deemed automatically to have assumed all of Tenant’s
obligations under this Lease.

          17.13 Sale by Landlord. In the event of any sale of the Building or
Property, or any assignment of this Lease by Landlord, Landlord shall be
relieved of all liability under this Lease arising out of any act, occurrence,
or omission occurring after sale or assignment; and the purchaser or assignee at
such sale or assignment or any subsequent sale or assignment of Lease, the
Property, or Building, shall be deemed without any further agreement to have
assumed all of the obligations of the Landlord under this Lease accruing after
the date of such sale or assignment. Notwithstanding the foregoing, except in
the event of a foreclosure or transfer in lieu of foreclosure, Landlord shall
make good faith efforts to obtain from the purchaser or assignee a written
assumption of Landlord’s obligations under this Lease.

          17.14 Successors and Assigns. Subject to the provisions of this
Section 17, this Lease shall be binding upon and inure to the benefit of the
parties, their heirs, successors and assigns.

     18. Default.

SECURITIES AND EXCHANGE COMMISSION.]

          18.1 The occurrence of any one or more of the following events shall
constitute a material default and breach of the Lease by Tenant (“Default”):

               18.1.1 vacation or abandonment of all or any portion of the
Premises;

               18.1.2 failure by Tenant to make any payment of Base Monthly
Rent or Operating Expenses as and when due or failure by Tenant to make any
other payment required hereunder within five (5) Business Days after notice that
such payment is due;

               18.1.3 failure by Tenant to observe or perform any of the
covenants, conditions, or provisions of this Lease, other than the making of any
payment, where such failure shall continue after thirty (30) days written notice
from Landlord; provided, however, that if more than thirty (30) days are
reasonably required to complete a cure, Tenant shall not be in default so long
as it commences cure within such period and diligently pursues completion within
a reasonable period of time thereafter;

               18.1.4 the making by Tenant of any general assignment or
general arrangement for the benefit of creditors; (ii) the filing by or against
Tenant of a petition in bankruptcy, including reorganization or arrangement,
unless, in the case of a petition filed against Tenant the same is dismissed
within thirty (30) days; (iii) the appointment of a trustee or receiver to take
possession of substantially all of Tenant’s assets located at the Premises or of
Tenant’s interest in this Lease; (iv) the seizure by any department of any
government or any officer thereof of the business or property of Tenant; and (v)
adjudication that Tenant is bankrupt.

               18.1.5 Failure to provide the Letter of Credit as and when
required.

               18.1.6 Failure to execute and return any estoppel certificate
or subordination agreement required pursuant to this Lease within the time
limits set forth herein, and such failure is not cured within five (5) days
after written notice of such failure.

          18.2 Tenant shall notify Landlord promptly of any Default by Tenant
(or event or occurrence which, with the passage of time, the giving of notice,
or both, would become a Default) that by its nature is not necessarily known to
Landlord.

          18.3 Landlord shall not be in default unless it fails to observe or
perform any of the covenants, conditions, or provisions of this Lease and such
failure continues for thirty (30) days after written notice from Tenant
specifying the Landlord’s obligations that remain unsatisfied (the “Tenant
Notice”); provided, however, that if the nature of Landlord’s obligation is such
that more than thirty (30) days are required for performance, Landlord shall not
be in default if Landlord commences performance within thirty (30) days after
receipt of the Tenant Notice and thereafter completes such performance
diligently and within a reasonable time. Tenant shall copy Landlord’s lender
with any Tenant Notice if Tenant has been provided with the name and address of
any such lender. If Landlord has not commenced or is not diligently pursuing
performance of such obligations thirty (30) days after Landlord’s receipt of the
Tenant Notice, then Tenant may send Landlord and its lender a second notice
stating the measures that Tenant will take to complete such obligations if
Landlord does not do so within three (3)

[*CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS
DOCUMENT. EACH SUCH PORTION, WHICH HAS BEEN OMITTED HEREIN AND REPLACED WITH A

SECURITIES AND EXCHANGE COMMISSION.]

business days after receipt of such second notice. If Landlord does not perform
such obligations during such period then Tenant may take the steps outlined in
its notice at Tenant’s expense and at Tenant’s sole risk. Notwithstanding the
foregoing, prior notice shall not be required in any emergency situation posing
a threat of imminent injury to persons or property provided that Tenant must
makes good faith efforts to notify Landlord prior to completing any of
Landlord’s obligations and provided further that Tenant must immediately
thereafter provide written notice to Landlord outlining in detail the measures
taken. Any such cure by Tenant shall be undertaken only by experienced,
qualified contractors and shall be performed in accordance with all applicable
Laws. Tenant shall immediately repair any damage caused by Tenant or its
contractors in the course of performing such work. If Tenant elects to pursue
such self-help rights then Tenant shall be solely responsible for and shall
indemnify Landlord against any liabilities, costs, damages or other losses
incurred by Landlord as a result of Tenant’s performance, including but not
limited to any claim of loss or damage by any other occupant in the Building and
any reasonable legal fees or other costs incurred related thereto. Tenant shall
have no right to offset any costs incurred against sums due hereunder unless
Landlord has agreed in writing to such offset.

          18.4 In no event shall a default by Landlord under this Lease give
rise to any right of Tenant to terminate this Lease. In no event shall a default
by Landlord under this Lease give rise to any right of Tenant to withhold or
offset the payment of Base Monthly Rent or Additional Rent and such obligations
shall continue unaffected in all events unless suspended or terminated pursuant
to an express provision of this Lease.

     19. Remedies in Default.

          19.1 Remedies. In the event of any Default by Tenant, Landlord may,
at any time without waiving or limiting any other right or remedy, do any one or
more of the following: (i) re-enter and take possession of the Premises, (ii)
pursue any remedy allowed by law or equity, and/or (iii) terminate this Lease.

          19.2 Costs. Whether Landlord has elected to terminate this Lease or
not, Tenant agrees to pay Landlord the cost of recovering possession of the
Premises, the expenses of reletting, and any other costs or damages arising out
of Tenant’s Default including without limitation the costs of removing persons
and property from the Premises, the costs of preparing or altering the Premises
for reletting, broker’s commissions, and attorneys’ fees.

          19.3 Reentry. No reentry or taking possession of the Premises by
Landlord pursuant to this Section 19, or acceptance of Tenant’s keys to or
surrender of the Premises shall be construed as an election to terminate this
Lease unless a written notice of such intention is given to Tenant.

          19.4 Damages. Notwithstanding termination of this Lease and reentry
by Landlord pursuant to Section 18, Landlord shall be entitled to recover from Tenant:

               19.4.1 The worth at the time of an award (including interest
at the rate set forth in Section 33.8), of any unpaid rent which had been earned
by Landlord prior to the time of termination; plus

29

 

[*CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS
DOCUMENT. EACH SUCH PORTION, WHICH HAS BEEN OMITTED HEREIN AND REPLACED WITH A
SERIES OF THREE ASTERISKS IN BRACKETS [***], HAS BEEN FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION.]

               19.4.2 The worth at the time of an award (including interest
at the rate set forth in Section 33.8), of the amount by which the unpaid rent
which would have been earned after termination until the time of an award
exceeds the amount of loss of rent that Tenant proves could have been reasonably
avoided; plus

               19.4.3 The worth at the time of an award of the amount by
which the unpaid rent and additional rent for the balance of the term of this
Lease (as extended, if at all prior to termination) exceeds the amount of such
loss of rent and additional rent that Tenant proves could have been reasonably
avoided (including interest at the rate set forth in Section 33.8 from the date
of the award until paid). Such worth of the time of award shall be computed at
the discount rate of the Federal Reserve Bank of San Francisco, or successor
Federal Reserve Bank, on the date of termination; plus

               19.4.4 The unamortized amount, over the initial Term, of any abated
rent at the commencement of the Term and the unamortized Allowance plus brokers
commissions and other costs incurred by Landlord in connection with this Lease;
plus

               19.4.5 Any other amount necessary to compensate Landlord for all the
damage proximately caused by Tenant’s failure to perform Tenant’s obligations
under this Lease or which in the ordinary course of things would be likely to
result therefrom.

          19.5 No Termination of Lease. No act of Landlord other than a
written declaration of termination of Lease shall serve to terminate this Lease.
Notwithstanding any reentry or termination, the liability of Tenant for the Rent
shall continue for the balance of the Term, and Tenant shall make good to
Landlord any deficiency arising from reletting the Premises at a lesser rent
than the Rent provided for in this Lease. If Landlord reenters the Premises
pursuant to this Section 19, and does not elect to terminate this Lease, Tenant
shall indemnify Landlord for the loss of rent by a payment at the end of each
month during the remaining Term representing the difference between the Base
Monthly Rent, and other charges which would have been paid in accordance with
this Lease and the rental actually derived from the Premises by Landlord for
such month. Separate actions may be maintained by Landlord against Tenant from
time to time to recover any damages which, at the commencement of any action,
are then due and payable to Landlord under this Lease without waiting until the
end of the Term of this Lease.

          19.6 Reletting. If this Lease is terminated, Landlord may at any
time, and from time to time, relet the Premises in whole or in part either in
its own name or as agent of Tenant for any period equal to or greater or less
than the remainder of the then-current Term. All rentals received by Landlord
from such reletting shall be applied first to the payment of any amounts other
than rent due hereunder from Tenant to Landlord; second, to the payment of any
costs and expenses of such reletting and of alterations and repairs; third, to
the payment of Base Monthly Rent and Additional Rent due and unpaid hereunder;
and the residue, if any, shall be held by Landlord and applied in payment of
future Rent as it becomes due hereunder. Upon a reletting of the Premises,
Landlord shall not be required to pay Tenant any sums received by the Landlord
in excess of amounts payable in accordance with this Lease. Landlord shall use
reasonable efforts to mitigate its damages.

SECURITIES AND EXCHANGE COMMISSION.]

          19.7 Right of Landlord to Cure Defaults. If Tenant defaults under
this Lease beyond any applicable notice or cure period, Landlord may cure the
default, at Tenant’s expense, immediately and without notice in case of
emergency threatening harm to persons or property, or in any other case only
upon Tenant’s failure to remedy such default within twenty (20) days after
Landlord notifies Tenant in writing of such default or, if more than twenty (20)
days are reasonably required to complete a cure, only if Tenant fails to
commence cure within such period or to diligently pursue completion within a
reasonable period of time thereafter. Tenant shall reimburse Landlord for any
costs of the cure with interest pursuant to Section 33.8. Landlord shall have
the same rights and remedies as for the nonpayment of sums due under this
Section 19 as in the case of default by Tenant in the payment of Rent.

     20. Access. Tenant shall permit Landlord to enter the Premises at all
reasonable times upon reasonable notice (which may be oral notice) for the
purpose of inspecting, altering, repairing and maintaining the Premises and the
Building and ascertaining compliance with the provisions of this Lease by
Tenant. The existence or exercise of such right of access shall not be construed
as imposing any obligation on Landlord to inspect, discover or correct or repair
any condition in the Premises or the Building. Landlord may also show the
Premises to prospective lenders and purchasers at reasonable times during the
Term and to tenants during the last nine (9) months of the Term or at any time
when Tenant is in default beyond any applicable notice or cure period, provided
that (except in an emergency) Landlord shall use commercially reasonably efforts
not to materially interfere with Tenant’s business operations. Tenant shall
provide Landlord with means of access to all areas of the Premises (other than
safes and vaults) but Landlord may use any means of gaining access necessary in
an emergency situation. No such entry shall be deemed to be a constructive
eviction of Tenant.

     21. Hold-Over Tenancy. If Tenant shall hold over after the expiration or
termination of the Term with Landlord’s written consent Tenant shall be deemed
to be occupying the Premises as a Tenant from month to month, which tenancy may
be terminated by either party on thirty (30) days notice. During such month to
month tenancy the Base Monthly Rent shall be one hundred twenty five percent
(125%) of the Base Monthly Rent payable in the last month prior to expiration or
termination of the Term, and Tenant shall continue to pay Additional Rent.
During any such tenancy, Tenant shall continue to be bound by all of the terms,
covenants, and conditions of this Lease, insofar as applicable. If Tenant shall,
without the written consent of Landlord, hold over beyond the expiration of the
Term, Tenant shall be deemed to be a tenant at sufferance and no month to month
tenancy shall be created. During such period Tenant shall be bound by all the
terms, covenants and conditions as herein specified as far as applicable, except
Rent, which shall be Two Hundred Percent (200%) of the Rent due prior to the
expiration of the Term and, in addition, Tenant shall indemnify, defend, protect
and hold Landlord harmless from and against any and all damages payable by and
claims made against Landlord as a result of any delay in the delivery of
possession under any subsequent lease or delay in closing of any sale of all or
any part of the Premises, including, without limitation, attorneys’ fees and
Landlord’s lost revenues. For purposes of this Section, Tenant shall be deemed
to be in possession until such time as Tenant fully vacates the Premises and
completes all removal and restoration work required under this Lease.

     22. Compliance With Laws. Tenant shall not use the Premises or permit
anything to be done in or about the Premises which will in any way conflict with
any applicable law, statute,

ordinance, or governmental rule or regulation, including without limitation the
Americans with Disabilities Act and all regulations related thereto, and the
CC&R’s and any other restrictive covenants and obligations created by private
contracts which affect the use and operation of the Premises, Building, common
areas or Business Park, now or hereafter in force (“Laws”). Tenant shall at its
sole cost and expense promptly comply with all Laws and with the requirements of
any board of fire insurance underwriters, Insurance Service Office, or other
similar bodies now or hereafter constituted, relating to, or affecting the
specific use or occupancy of the Premises; provided, however, Tenant shall not
be required to cure any existing violation of Laws unless cure is required as a
condition to Tenant’s use of the Premises or because of any alterations that
Tenant desires to make to the Premises. The judgment of any court of competent
jurisdiction, whether Landlord be a party thereto or not, that Tenant has
violated any Laws, shall be conclusive of the fact as between Landlord and
Tenant.

     23. Rules and Regulations. Tenant shall faithfully observe and comply with
any reasonable rules and regulations that Landlord shall from time to time
promulgate including but not limited to the rules attached hereto as Exhibit C.
Tenant shall cause all of its employees, agents, contractors, assignees,
subtenants, invitees and guests to comply with such rules and regulations.
Landlord reserves the right from time to time to make all reasonable
modifications to such rules and regulations. Additions and modifications to
rules and regulations shall be binding on Tenant upon delivery of a copy of them
to Tenant. Landlord shall not be responsible to Tenant for the nonperformance of
any rules or regulations by any other person so long as such modifications apply
equally to all tenants.

     24. Parking. To the extent permitted by the CC&Rs and other documents
presently recorded against the Property, Tenant shall have the non-exclusive
right to use Tenant’s Share of all parking spaces located on the Property during
the Term without charge on an unreserved, first-come, first-served basis. Such
use by Tenant shall comply with all Laws and shall be subject to any reasonable
rules and regulations that may be established by Landlord and any rules and
regulations established pursuant to the CC&Rs for such parking facilities from
time to time. Landlord may alter the parking areas (so long as such alterations
do not decrease the number of parking spaces below what is required by the terms
of this Lease or required by law) and may assign some or all of the parking
spaces to Building tenants from time to time.

     25. Estoppel Certificates. Tenant shall execute, within ten (10) days
following Landlord’s request a certificate in such form as may be reasonably
required by Landlord or a prospective purchaser, mortgagee or trust deed
beneficiary, or Landlord’s successor after a sale or foreclosure, certifying:
(i) the Commencement Date of this Lease; (ii) that the Lease is unmodified and
in full force and effect, (or if there have been modifications hereto, that this
Lease is in full force and effect, and stating the date and nature of such
modifications); (iii) that to the best of Tenant’s knowledge, there have been no
defaults under this Lease by either Landlord or Tenant except as specified in
Tenant’s statement; (iv) the dates to which the Base Monthly Rent, Additional
Rent and other charges have been paid; and (v) any other information reasonably
requested by the requesting party. Such certificate may be relied upon by
Landlord and/or such other requesting party. Tenant’s failure to deliver such
statement within such time shall be an event of Default hereunder.

     26. Subordination. Tenant agrees that this Lease shall be subordinate to
the lien of any mortgage, deeds of trust or ground leases now or hereafter
placed against the Property or Building, and to all renewals and modifications,
supplements, consolidations, and extensions thereof. Notwithstanding the
foregoing, Landlord reserves the right however, to subordinate or cause to be
subordinated any such mortgage, deed of trust or ground lease to this Lease.
Upon a foreclosure or conveyance in lieu of foreclosure under such mortgage or
deed of trust, or a termination of such ground lease, and a demand by Landlord’s
successor, Tenant shall attorn to and recognize such successor as Landlord under
this Lease provided such successor agrees to perform Landlord’s obligations
arising thereafter. Tenant shall execute and deliver on request and in the form
requested by Landlord, any instruments reasonably necessary or appropriate to
evidence, effect or confirm such subordination. Should Tenant fail to sign and
return any such documents that comply with this Section or to provide specific
written objections to such documents stating in particular how the documents
fail to comply with this Lease within ten (10) Business Days of the request,
Tenant shall be in Default.

     27. Surrender; Removal of Property. Tenant shall surrender the Premises to
Landlord upon the expiration or sooner termination of this Lease, with all
equipment therein in good, working condition and repair and in the same or
better condition as upon delivery, excluding ordinary wear and tear. On or
before the expiration or termination of this Lease, Tenant shall: (i) remove
from the Premises all of its personal property, including any furniture,
equipment and signage; (ii) remove from the Premises any cabling installed by
Tenant; and (iii) remove from the Premises any improvements or alterations
installed by Tenant which Landlord directs Tenant to remove. With respect to any
alterations or improvements for which Tenant requests Landlord’s approval, if
Tenant requests Landlord to do so in writing, Landlord shall notify Tenant at
the time of such approval if the alterations or improvements are subject to this
removal obligation. If Landlord does not so notify Tenant at that time then
Tenant shall not be required to remove such alterations or improvements upon
surrender. Notwithstanding the foregoing, Tenant shall not be required to remove
any standard office improvements installed by Tenant provided that standard
office improvements shall not include structural alterations, raised floors,
internal stairways, high density storage systems, additional baths or kitchen
areas, or vaults. Any and all damage done to the Premises or the Building as a
result of Tenant’s installation or removal of any personal property, fixtures,
furnishings or signage shall be repaired and the Premises restored, at Tenant’s
expense. Tenant shall deliver to Landlord all access cards or keys to all locks
in the Premises. If Tenant fails to remove any of the foregoing items or to
repair any damage required to be repaired hereunder, Landlord shall be entitled
to remove any of the foregoing items and to make such repairs, at Tenant’s
expense, and shall further be entitled to draw upon the Letter of Credit for
such costs. Landlord shall not be required to return any portion of the Letter
of Credit proceeds until Tenant’s obligations with respect to removal and
restoration have been satisfied and Tenant shall be considered a hold-over
tenant until such work is completed. All personal property remaining on the
Premises after reentry or termination of this Lease shall conclusively be deemed
abandoned and may be removed by Landlord. Landlord may store such property in
any place selected by Landlord, including but not limited to a public warehouse,
at the expense and risk of the owner thereof, with the right to sell such stored
property without notice to Tenant. The proceeds of such sale shall be applied
first to the cost of such sale, second to the payment of the cost of removal and
storage, if any, and third to the payment of any other amounts that may then be
due from Tenant to Landlord under this Lease.

     28. Personal Property Taxes. Tenant shall pay, prior to delinquency, all
Personal Property Taxes (as defined below) payable with respect to all Tenant’s
Property (as defined below) located on the Premises or in the Building and
promptly upon request of Landlord shall provide written proof of such payment.
As used herein, “Tenant’s Property” shall mean and include, without limitation,
all personal property owned by Tenant including inventory, equipment, furniture,
fixtures and trade fixtures kept or used on or installed in the Premises and any
Tenant Improvements and other improvements to the Premises that are owned by and
separately assessed to Tenant. “Personal Property Taxes” shall include all
property taxes assessed against the Tenant’s Property, whether assessed as real
or personal property.

     29. Notices. All notices under this Lease shall be in writing. Notices
shall be effective (i) three (3) days after the date of mailing by certified
mail, return receipt requested, (ii) upon delivery when delivered personally or
by commercial messenger service, or (iii) the next Business Day after the date
of mailing if delivered by a nationally recognized delivery service such as
Federal Express, in each case to the notice address(es) of the receiving party
set forth in Section 1. Either party may change its address(es) for notices by
notice to the other from time to time except that, after the Term commences, any
notice to Tenant may be so mailed or delivered by hand to Tenant at the
Premises. All service of process on Tenant may be accomplished at the Premises
or by service on Tenant’s registered agent in the State of Washington.

     30. Condition of Premises. By taking possession of the Premises, Tenant
accepts the Premises as being in good, sanitary order, condition and repair, and
further accepts all aspects of the Premises, Building, Property and Business
Park in their present condition, AS IS, including latent defects, without any
representations or warranties, express or implied, from Landlord, unless
otherwise set forth herein.

     31. Hazardous Materials.

          31.1 Restriction on Use. Tenant and Tenant’s officers, contractors,
subcontractors, licensees, agents, servants, employees, guests, invitees or
visitors, or any assignee or sublessee or other person for whom Tenant would
otherwise be liable (individually, a “Tenant Party” and collectively, “Tenant
Parties”) shall comply with all Environmental Laws (as defined below) in
connection with Tenant’s or Tenant Parties use, production, storage or disposal
of any Hazardous Materials (as defined below) on, under or about the Premises.
Tenant hereby represents, warrants, covenants and agrees that all operations or
activities upon, or any use or occupancy of the Premises, or any portion
thereof, by Tenant or any Tenant Party of the Premises or any portion thereof,
shall be in all material respects in compliance with all state, federal and
local laws and regulations governing or in any way relating to the generation,
handling, manufacturing, treatment, storage, use, transportation, spillage,
leakage, dumping, discharge or disposal (whether legal or illegal, accidental or
intentional) of any Hazardous Materials. Neither Tenant nor any Tenant Party
shall use or dispose of any Hazardous Materials in or on the Premises, the
Building, the Project, or any adjacent property, or in any improvements thereto,
except for such Hazardous Materials as are essential to the operation of
Tenant’s and Tenant Parties’ business and reported to Landlord not less often
than annually, and then only in accordance with all applicable laws and
regulation provided however, that in no event shall Tenant use any Hazardous
Materials that are classified as Biosafety level 3 (BSL 3)

or 4 (BSL 4). Tenant shall, and shall ensure that all Tenant Parties shall, at
all times comply with Environmental Laws and best industry standard research,
medical and safety practices in connection with the use, handling, production
storage or disposal of any Hazardous Material, including, but not limited, to
any Medical Products (as defined below), at Tenant’s sole expense. Tenant shall
only generate, release, store, deposit, transport, or dispose of (collectively
“Release”) any hazardous substances, sewage, petroleum products, hazardous

hazardous or toxic in applicable federal, state and local laws and regulations
(“Hazardous Substances”) in, on or about the Premises necessary for its

          31.2 Air Quality. Tenant and Tenant Parties shall design and
construct their Tenant Improvements, including any upgraded HVAC and plumbing
systems, using best available commonly used industry technique designed to
ensure that Tenant’s and Tenant Parties’ Hazardous Materials do not compromise
the air quality outside the Premises or in any space occupied by other tenants
(including Tenant’s subtenants) or allow the possibility of water system back-up
into the Building or otherwise migrate to any adjacent space occupied by any
other tenant. In particular, Tenant shall use, and shall require Tenant Parties
to use best-available, commonly used industry techniques to prevent air mixing
from areas of potential contamination into other areas of the Building. Tenant
shall indemnify and hold Landlord harmless from and against any and all losses,
expenses, liabilities, penalties or costs arising directly or indirectly from
Tenant’s or Tenant Parties’ failure to isolate building systems or to cause an
Environmental Condition in areas of the Project outside the Premises as a result
of its design or construction of the Tenant Improvements.

          31.3 Reporting. Tenant shall deliver (or cause Tenant Parties to
deliver) to Landlord (a) prior to Lease execution, and (b) once each year on or
before January 1st during the Term, a list specifying the type and quantity of
all Hazardous Materials used or stored by Tenant or Tenant Parties on the
Premises together with copies of all permits, licenses and approvals required in
connection with the use or storage of such materials, together with Tenant’s and
Tenant Parties’ Hazardous Materials data safety sheets and any other
documentation with respect to Tenant’s and Tenant Parties’ usage, storage, and
disposal of Hazardous Materials that are required by the City of Bothell Fire

Tenant Parties to respond to any written request by Landlord for confirmation
whether there has been a significant increase, as evaluated in Tenant’s
reasonable judgment, in the quantity of Hazardous Materials or change in the
type of Hazardous Materials utilized by Tenant or Tenant Parties, provided that
such request shall not be made more than once per calendar quarter. Tenant will
provide additional documents or information with respect to its and Tenant
Parties’ Hazardous Materials within a reasonable period of time after receipt of
a specific written request from Landlord. Tenant shall promptly notify Landlord
in writing of (i) any notices of violation or potential or alleged violation of
any Environmental Law which are received by Tenant from any governmental agency
or any Tenant Party; (ii) any and all inquiry, investigation, enforcement,
clean-up, removal or other governmental or regulatory actions instituted or
threatened relating to the Premises; and (iii) all claims made or threatened by
any third-party against Tenant or a Tenant Party or the Premises relating to any
Hazardous Materials used by Tenant or a Tenant Party at the Premises. If any
Environmental Condition occurs that is or may be a result of Tenant’s or any
Tenant Party’s actions during the Initial or Extended Term, or if Tenant or any
Tenant Party has disposed of or caused a release of Hazardous Materials at, on
or about the Project other than in accordance with Environmental Laws, Tenant
shall promptly prepare or cause the Tenant Party to prepare a remediation plan
for Landlord’s review and approval, which shall not be unreasonably withheld,
provided, however, that Landlord shall not require any remediation in excess of
or to higher standards than would be mandated by applicable Environmental Laws.
Tenant’s obligation to remediate any Environmental Condition shall not be
contingent on an enforcement action by any governmental authority and shall be
independent of any governmentally mandated remediation. If Landlord approves the
plan, then Tenant shall execute or cause the Tenant Party to execute the
remediation plan at Tenant’s sole cost and expense (subject to such
reimbursement as Tenant may obtain from a Tenant Party). If the remediation plan
is not

reasonably acceptable to Landlord or if Tenant fails to execute or cause
execution of the remediation plan within a reasonable period of time, then, at
Landlord’s option, Tenant shall reimburse Landlord, upon demand, for the cost to
Landlord of performing rectifying work provided that such work is not in excess
of or to higher standards than would be mandated by applicable Environmental
Laws. The reimbursement shall be paid to Landlord in advance of Landlord’s
performing such work, based upon Landlord’s reasonable estimate of the cost
thereof; and upon completion of such work by Landlord, Tenant shall pay to
Landlord any shortfall within thirty (30) days after Landlord bills Tenant
therefor or Landlord shall within thirty (30) days refund to Tenant any excess
deposit, as the case may be. To the extent reasonably requested by Landlord,
Tenant shall furnish Landlord with detailed reports concerning any Environmental
Condition which occurs on the Premises during the Term. Tenant shall not be
responsible for any pre-existing Hazardous Material (other than building
materials) which, as between Landlord and Tenant, shall be Landlord’s sole
responsibility unless the condition is exacerbated by Tenant.

          31.4 Inspection. After notice to Tenant and a reasonable opportunity
for Tenant to effect such compliance, Landlord may, but shall not be obligated
to, enter upon the Premises (including subleased Premises) and take such actions
and incur such costs and expenses to effect such compliance as it deems
advisable to protect its interest in the Premises. However, Landlord shall not
be obligated to give Tenant notice and an opportunity to effect compliance if
(i) such delay might result in material adverse harm to Landlord, the Premises,
the Building or the Project; (ii) Tenant has already had actual knowledge of the
situation and a reasonable opportunity to effect compliance and Tenant has
failed to do so; or (iii) Landlord reasonably believes that an emergency exists.
Landlord shall use good faith efforts to comply with Tenant’s reasonable
requirements with respect to security to the extent such requirements have been
provided to Landlord in advance. Whether or not Tenant has actual knowledge of
the release of Hazardous Materials on the Premises, the Building, or the Project
as the result of Tenant’s or Tenant Parties’ specific use of the Premises, the
Building or the Project, Tenant shall reimburse Landlord for all reasonable
costs and expenses incurred by Landlord relating to such Hazardous Materials or
in connection with such compliance activities. Tenant shall notify Landlord
immediately of any release of any Hazardous Materials on the Premises in
violation of any Environmental Law of which Tenant is aware.

          31.5 Indemnity. Tenant agrees to indemnify, defend and hold harmless
Landlord against any and all losses, liabilities, suits, obligations, fines,
damages (including diminution in the value of the Premises or Building, loss or
restrictions on use of space in the Building or Project, and sums paid in
settlement of claims), judgments, penalties, claims, charges, cleanup costs,
remedial actions, costs and expenses (including, without limitation, attorneys’
and other professional fees and disbursements) that may be imposed on, incurred
or paid by, or asserted against Landlord, the Premises, the Building, or the
Project by reason of, or in connection with (i) any misrepresentation, breach of
warranty or other default by Tenant or any Tenant Party under this Section, or
(ii) the acts or omissions of Tenant or any Tenant Party resulting in the
release of any Hazardous Materials. All of Tenant’s obligations and liabilities
under this Section shall survive expiration or other termination of this Lease
and shall be separately enforceable by Landlord. This indemnification is
intended to constitute an indemnity agreement within the meaning of Section
9607(e)(i) of the Comprehensive Environmental Response, Compensation and
Liability Act of 1980 (42 U.S.C. Section 9607(e)(i)). Neither the written

the Premises, nor the strict compliance by Tenant with all Environmental Laws,

may have been exposed to Hazardous Materials brought into the Premises by or on
behalf of Tenant, including but not limited to scrubbing of all surfaces,
equipment, cabinets, fixtures and flume hood external surfaces in the Premises,
in order to remove all residues of Hazardous Materials (including chemicals and
biological material). Upon completion of such wash and decontamination, Tenant
shall cause, at its sole cost and expense, a reputable environmental engineering
company to perform an environmental inspection of the Premises and prepare a
written report for delivery to Landlord and Tenant no later than thirty (30)
days after Lease expiration or early termination, certifying that the Premises
are free from all Hazardous Materials.

          31.7 Monitoring. At its option, Landlord may once in each Lease
year, and more frequently if Landlord has reasonable cause to believe that a
violation of Environmental Law or this Section 31 is occurring, monitor Tenant’s
and Tenant Parties’ compliance with the requirements set forth in this Section,
including without limitation obtaining an environmental assessment or inspection
of the Premises from a qualified environmental engineering company of Landlord’s
selection which has demonstrated industry related experience, the cost of which
shall be paid by Landlord unless such assessment shows a material failure by
Tenant or Tenant Parties to comply with the requirements of this Section, in
which case the cost shall be paid by Tenant. Any such environmental assessment
or inspection shall be performed at a reasonable time mutually acceptable to
Landlord and Tenant (and coordinated with Tenant Parties). Landlord shall
provide a copy of any written report to Tenant and, Tenant shall comply (and
cause Tenant Parties to comply), at Tenant’s cost and expense (provided that
Tenant may seek to have Tenant Parties bear costs so long as the work is done),
with any industry-standard recommendations contained in any such environmental
assessment that Landlord may reasonably require including without limitation,
any recommended precautions which should be taken with respect to Tenant’s or
Tenant Parties’ activities on the Premises.

drapes, or other materials without the written consent of Landlord. Tenant shall
observe and comply with the requirements of all Laws. Tenant shall have the
right, at Tenant’s expense, to install identifying signage on the Building
directory, the Building, the Premises, and on the monument sign for the
Building, provided that such signage is permitted under applicable Laws.
Landlord shall have the right to review and reasonably approve Tenant’s proposed
signage which shall be included in Tenant’s Plans pursuant to Exhibit B. Subject
to the rights of any current tenants, Tenant shall have the right to the most
prominent position on the monument sign provided that Tenant’s signage shall not
exceed Tenant’s Share of the total space available on the monument sign. If
permitted by applicable laws and any conditions, covenants or restrictions
applicable to the Business Park or

approval of the design and location, construct a second monument sign to
identify Tenant’s business in the Premises.

     33. General Provisions.

          33.1 Attorneys’ Fees. In the event Landlord reasonably requires the
services of any attorney in connection with any default or violation by Tenant
of the terms of this Lease or the exercise by Landlord of its remedies for any
default by Tenant under this lease, or a request by Tenant for Landlord’s waiver
of any terms of this Lease or extension of time to perform or pay any obligation
of Tenant under this Lease, Tenant shall promptly on demand reimburse Landlord
for its reasonable attorneys’ fees incurred in such instance. In the event of
any litigation, arbitration or other proceeding (including proceedings in
bankruptcy and probate and on appeal) brought to enforce or interpret or other
wise arising under this Lease, the substantially prevailing party therein shall
be entitled to the award of its reasonable attorneys’ fees, witness fees, and
court costs incurred therein and in preparation therefor.

          33.2 Governing Law. This Lease shall be governed by and construed in
accordance with the laws of the State of Washington. Any suit arising from or
relating to this Lease shall be brought in the county in which the Premises are
located, and the parties hereto waive the right to be sued elsewhere.

          33.3 Cumulative Remedies. No remedy or election under this Lease

this Lease are a part of and incorporated into this Lease.

          33.5 Interpretation. This Lease has been submitted to the scrutiny

and reasonable interpretation in accordance with the words hereof, without
consideration or weight being given to its having been drafted by any party
hereto or its counsel. Tenant acknowledges that it has had an opportunity to be
represented by legal counsel during the course of such negotiations.

          33.6 Joint Obligation. If there is more than one Tenant under this
Lease, the obligations hereunder imposed upon Tenants shall be joint and
several.

vaults, if any, in the Premises.

          33.8 Late Charges; Interest. Late payment by Tenant to Landlord of
Rent or other sums due under this Lease will cause Landlord to incur costs not
contemplated by this Lease, the exact amount of which would be difficult and
impractical to ascertain. Such costs include without limitation processing and
accounting charges and late charges which may be imposed on Landlord by the
terms of any mortgage or trust deed covering the Premises. Accordingly, Tenant
shall pay to Landlord as Additional Rent a late charge equal to the greater

of Two Hundred Fifty Dollars ($250) or five percent (5%) of such installment as
liquidated damages for such late payment, other than for time value damages.
Waiver of said late charge with respect to any installment or sum shall not be
deemed to constitute a waiver with respect to any subsequent late charge which
may accrue. Payment of the Rent via Tenant’s delivery of a check returned for
“Insufficient Funds” shall constitute the delinquent payment of Rent and shall
be subject to the late charge and interest provisions of this Section. In
addition, any Rent or other sums due under this Lease to Landlord that is not
paid when due shall bear interest at the rate of twelve (12%) per annum or the
maximum amount permitted by law if less, calculated from the date due or
expended until the date of payment. The existence or payment of charges and
interest under this Section shall not cure or limit Landlord’s remedies for any
Default under this Lease.

present status of light, air, or view in, to or from the Premises.

this Lease, and no prior agreements of understandings pertaining to any such
matters shall be effective for any purpose. No provision of this Lease may be

their respective successors in interest. This Lease shall not be effective or
binding on any party until fully executed by both parties hereto.

          33.12 No Recording. Neither this Lease nor any memorandum of this
Lease shall be recorded.

          33.13 Liability. Tenant recognizes that Landlord is a limited
partnership. Tenant expressly agrees, anything herein to the contrary
notwithstanding, that each and all of the representations and agreements made by
Landlord are intended to bind only the Premises. No personal liability or

enforced against, any of the managers, shareholders, partners, directors,
officers, employees or agents of Landlord on account of any agreements of
Landlord contained in this Lease and Tenant expressly waives any right to
proceed against the partners or the officers, directors, or shareholders of any
partner in Landlord, except to the extent necessary to subject the assets of
such partnership to such claim. If Landlord fails to perform any obligation of
Landlord under this Lease and as a result Tenant recovers a money judgment
against Landlord, such judgment shall be satisfied only out of the proceeds of
sale received upon execution of such judgment and levied against the right,
title and interest of Landlord in the Property.

          33.14 Severability. That any provision of this Lease is invalid,

          33.16 Waiver. No provision of this Lease shall be deemed to have
been waived by Landlord unless such waiver is in writing signed by Landlord. The
waiver by either party of any provision of this Lease shall not be deemed to be
a waiver of such provision or any other provision, in any subsequent instance.
The acceptance of Rent by Landlord shall not be deemed to be a waiver of any
preceding default or breach by Tenant under this Lease, whether known or unknown
to Landlord, other than the failure of the Tenant to pay the particular Rent so
accepted.

occupancy permit despite diligent pursuit thereof, shortages of labor or
materials because of priority or similar regulations or order of any
governmental or regulatory body, war, or any other causes of any kind which are
beyond the reasonable control of said party. Lack of funds or inability to
obtain financing shall not constitute force majeure.

     34. Rooftop Equipment. Landlord shall permit Tenant to install and
maintain at Tenant’s sole expense communications equipment to be used solely for
communications from or to Tenant (“Communications Equipment”) on the roof of the
Building in locations acceptable to Landlord and in strict compliance with all
applicable governmental laws and regulations and Landlord’s roof warranty. The
Communications Equipment may not be leased or hired out to any third parties and

Tenant establishes to Landlord’s satisfaction that the Building roof and
structure are adequate to support the HVAC Equipment. Tenant shall provide full
and complete plans for any rooftop HVAC Equipment to Landlord for its review and
approval prior to installing such equipment. Landlord makes no warranties or
representations to Tenant as to the permissibility of any HVAC Equipment on the
Building under applicable law or as to the ability of the Building to support
additional rooftop HVAC Equipment. Tenant shall be required to obtain all
governmental permits, consents or authorizations necessary for the installation
and operation of the HVAC Equipment and shall be solely responsible for any
repair and maintenance thereof. Tenant shall use a contractor approved by
Landlord to install the HVAC Equipment and shall cause such work to be done in a
manner that will not damage the roof or any other part of the Building and to

Equipment may not in any way interfere with the systems of the Building or the
quiet enjoyment of other tenants of the Building or any other tenant’s rooftop
equipment. Tenant acknowledges that other tenants of the Building have or will
be installing antenna and related equipment in or on the Building and Tenant
agrees to cooperate with such other tenants so as to avoid interference among
users. If installation, maintenance, use, or removal of any equipment on the
rooftop causes any damage to the roof or roof membrane or any other portion of
the Building, then Tenant shall be solely responsible for such damage and shall
ensure that the remaining useful life of the roof is the same as it would have
been but for the penetrations. Tenant’s insurance and indemnification

activities of Tenant in relation thereto.

EXHIBIT B

CONSTRUCTION OF TENANT IMPROVEMENTS

     This Exhibit constitutes a part of the Lease and its terms are incorporated in the Lease for
all purposes. Capitalized terms used herein and not otherwise defined shall have the meanings
given in the Lease.

I. LANDLORD’S OBLIGATIONS.

     A. Delivery. Landlord shall deliver the Premises to Tenant in their current condition and
shall not be obligated to construct any improvements or additions to the Premises nor shall
Landlord be required to upgrade the Building structure or systems to accommodate Tenant’s planned
improvements. Tenant accepts the Premises in their current As-Is condition, with all faults.
Tenant acknowledges that Landlord did not design or construct the Building or the existing
improvements therein. Nevertheless, Landlord has provided Tenant with copies of such plans and
specifications as the property manager may have in its possession with respect to the current
improvements in the Building. Landlord shall not be responsible for the completeness or accuracy of
such plans, all of which shall be provided for information purposes only and without warranty of
any kind.

     B. Allowance.

          (1) Provided Tenant is not in default under the Lease, Landlord shall reimburse Tenant for a
portion of the costs incurred by Tenant to construct its improvements in the Premises up to a
total of Fifteen and 00/100 Dollars ($15.00) per RSF (the “Allowance”). Reimbursable costs shall
include sums owed to Tenant’s contractor for labor in installing Tenant’s Work and the reasonable
cost of materials and equipment incorporated into the Premises as part of Tenant’s Work. The
Construction Allowance may also be used for Tenant’s communications systems and cabling, trade
fixtures, furniture and equipment to be installed in the Premises as well as any other costs
associated with Tenant’s initial build-out. If the cost of such work is estimated to exceed the
amount of the Construction Allowance, all additional costs shall be Tenant’s responsibility and
Tenant shall provide Landlord adequate security to ensure full and timely payment thereof.
Landlord shall have the right to offset any amount due and owing by Tenant under the Lease against
the Construction Allowance.

          (2) Landlord shall pay the Allowance to or on behalf of Tenant within ten (10) days after all
of the following conditions have been satisfied: (a) delivery of full and final lien waivers from
the general contractor and all subcontractors and materialmen or the expiration of the period of
time during which liens may be filed arising out of the labor and materials provided in connection
with Tenant’s Work, provided no liens have actually been filed or threatened; (b) Landlord’s
receipt of Tenant’s as built plans showing all improvements actually constructed in the Premises in
a format approved by Landlord; (c) Landlord’s receipt of a request for disbursement together with
invoices, statements and such other back-up documentation as may be reasonably appropriate to
establish and substantiate the costs for which Tenant seeks reimbursement hereunder; and (d) Tenant
shall have opened for business in the Premises. If any liens are filed against the Premises or the
Project arising out of Tenant’s work and said liens are not removed within fifteen (15) Business
Days of Landlord’s demand for their removal, Landlord shall be entitled to pay whatever costs
Landlord may consider appropriate to remove said liens and to offset said costs, including without
limitation any attorneys fees and costs,

against the Allowance. Tenant must spend the Allowance and request disbursement within one (1)
year after the Effective Date.

          (3) If Tenant breaches or defaults under any of the terms and provisions of the Lease during
the Term and the Lease is terminated or rejected, then in addition to all other remedies of
Landlord set forth in the Lease, Landlord may recover the unamortized portion of the Allowance,
plus interest thereon at the rate of twelve percent (12%) per annum. The period of amortization
shall be the Initial Term of the Lease and such amortization shall be made on a straight-line
basis. Landlord and Tenant specifically intend the recovery of Landlord’s Construction Allowance
pursuant to the preceding sentence shall not be limited or impaired by Section 502 or other
provision of the Bankruptcy Code. The foregoing shall be deemed to be a financial accommodation of
the type referenced in 11 U.S.C. § 365(c)(2) and a material and substantial part of this lease
transaction.

review, comment on and return the plans to Tenant, marked “Approved”, “Approved as Noted” or

into account the reasons for Landlord’s disapproval, and shall resubmit revised plans to Landlord
for review. The same procedure shall be repeated until Landlord fully approves the plans. Landlord
shall be entitled to reimbursement from Tenant on demand for the third-party costs incurred by
Landlord in reviewing plans hereunder.

Building. Tenant shall require that its architects, engineers and contractors verify all existing
conditions in the Building, insofar as they are relevant to, or may affect, the design and
construction of the Tenant Improvements.

     Approval by Landlord of the Tenant’s Plans prepared by Tenant shall not: (i) imply approval by
Landlord as to compliance of such plans with applicable regulations, laws, ordinances, codes and
rules; (ii) imply the compatibility of the plans with the Building; or (iii) limit Landlord’s
right, as a condition and at the time of Landlord’s approval, to require changes in portions of the
plans which are incompatible with or which, in the reasonable opinion of Landlord, adversely affect
the Building structure or the electrical, plumbing, life safety or mechanical systems of the
Building or which adversely affect the availability to Landlord of third party warranties. Tenant
acknowledges that both the compliance of the Tenant’s Plans with all applicable regulations, laws,
ordinances, codes and rules and the compatibility of the Tenant’s Plans with the Building structure
and the mechanical, plumbing, life safety and electrical systems of the Building are the
responsibility of Tenant.
