2.   LEASE GRANT.

     The Premises are hereby leased to Tenant from Landlord, together with the
right to use any portions of the Property that are designated by Landlord for
the common use of tenants and others (the "COMMON AREAS").

3.   ADJUSTMENT OF COMMENCEMENT DATE; POSSESSION.

     3.01 If Landlord is required to perform Landlord Work prior to the
Commencement Date: (a) the date set forth in Section 1.06 as the Commencement
Date shall instead be defined as the "TARGET COMMENCEMENT DATE"; (b) the actual
Commencement Date shall be the date on which the Landlord Work is Substantially
Complete (defined below); and (c) the Termination Date will be the last day of
the Term as determined based upon the actual Commencement Date. Landlord's
failure to Substantially Complete the Landlord Work by the Target Commencement
Date shall not be a default by Landlord or otherwise render Landlord liable for
damages. Promptly after the determination of the Commencement Date, Landlord and
Tenant shall enter into a commencement letter agreement in the form attached as
EXHIBIT D. Tenant's failure to execute and return the commencement letter, or to
provide written objection to the statements contained in the letter, within 30
days after the date of the letter shall be deemed an approval by Tenant of the
statements contained therein. If the Termination Date does not fall on the last
day of a calendar month, Landlord and Tenant may elect to adjust the Termination
Date to the last day of the calendar month in which the Termination Date occurs
by the mutual execution of a commencement letter agreement setting forth such
adjusted date. The Landlord Work shall be deemed to be "SUBSTANTIALLY COMPLETE"
on the date that all Landlord Work has been performed, other than any details of
construction, mechanical adjustment or any other similar matter, the
non-completion of which does not materially interfere with Tenant's use of the
Premises. If Landlord is delayed in the performance of the Landlord Work as a
result of the acts or omissions of Tenant, the Tenant Related Parties (defined
in Section 13) or their respective contractors or vendors, including, without
limitation, changes requested by Tenant to approved plans, Tenant's failure to
comply with any of its obligations under this Lease, or the specification of any
materials or equipment with long lead times (a "TENANT DELAY"), the Landlord
Work shall be deemed to be Substantially Complete on the date that Landlord
could reasonably have been expected to Substantially Complete the Landlord Work
absent any Tenant Delay.

If the Commencement Date has not occurred on or before the Outside Completion
Date (defined below), Tenant shall be entitled to a rent abatement following the
Commencement Date of $2,240.76 for every day in the period beginning on the
Outside Completion Date and ending on the Commencement Date. The "OUTSIDE
COMPLETION DATE" shall mean the later of (x) March 1, 2006 and (y) the date
which is 60 days after the later of the date this Lease is properly executed and
delivered by Tenant, the date all prepaid rental, Security Deposits and
Guaranties required under this Lease are delivered to Landlord, the date the
building permit for the Landlord Work has been obtained, and, if applicable, the
date all contingencies, if any, specified in this Lease have been satisfied or
waived in writing by Landlord. Landlord and Tenant acknowledge and agree that:
(i) the determination of the Commencement Date shall take into consideration the
effect of any Tenant Delays by Tenant; and (ii) the Outside Completion Date
shall be postponed by the number of days the Commencement Date is delayed due to
events of Force Majeure.

     3.02 Subject to Landlord's obligation, if any, to perform Landlord Work,
the Premises are accepted by Tenant in "as is" condition and configuration
without any representations or warranties by Landlord (except as otherwise
explicitly set forth herein). By taking possession of the Premises, Tenant
agrees that the Premises are in good order and satisfactory condition. Tenant's
acceptance of the Premises shall be subject to Landlord's obligation to correct
portions of the Landlord Work as set forth on a construction punch list prepared
by Landlord and Tenant in accordance with the terms hereof. Within 15 days after
Substantial Completion of the Landlord Work, Landlord and Tenant shall together
conduct an inspection of the Premises and prepare a "punch list" setting forth
any portions of the Landlord Work that are not in conformity with the Landlord
Work as required by the terms of this Lease. Notwithstanding the foregoing, at
the request of Landlord, such construction punch list shall be mutually prepared
by Landlord and Tenant prior to the date on which Tenant first begins to move
its furniture, equipment or other personal property into the Premises. Landlord,
as part of the Landlord Work, shall use good faith efforts to correct all such
items within a reasonable time following the completion of the punch list.
Landlord shall not be liable for a failure to deliver possession of the Premises
or any other space due to the holdover or unlawful possession of such space by
another party, however Landlord shall use reasonable efforts to obtain
possession of the space. The commencement date for the space, in such event,
shall be


                                       3

<PAGE>

postponed until the date Landlord delivers possession of the Premises to Tenant
free from occupancy by any party. If Tenant takes possession of the Premises
before the Commencement Date, such possession shall be subject to the terms and
conditions of this Lease and Tenant shall pay Rent (defined in Section 4.01) to
Landlord for each day of possession before the Commencement Date. However,
except for the cost of services requested by Tenant (e.g. freight elevator
usage), Tenant shall not be required to pay Rent for any days of possession
before the Commencement Date during which Tenant, with the approval of Landlord,
is in possession of the Premises for the sole purpose of performing improvements
or installing furniture, equipment or other personal property. Subject to the
terms of this Section 3, Landlord grants Tenant the right to enter the Premises
no earlier than 30 days prior to the Commencement Date, at Tenant's sole risk,
(i) following installation of the ceiling grid in the Premises, solely for the
purpose of installing telecommunications and data cabling in the Premises, and
(ii) following installation of the carpeting in the Premises, solely for the
purpose of installing equipment, furnishings and other personalty. Landlord may
withdraw such permission to enter the Premises prior to the Commencement Date at
any time that Landlord reasonably determines that such entry by Tenant is
causing a dangerous situation for Landlord, Tenant or their respective
contractors or employees, or if Landlord reasonably determines that such entry
by Tenant is hampering or otherwise preventing Landlord from proceeding with the
completion of Landlord's Work at the earliest possible date.

4.   RENT.

     4.01 Tenant shall pay Landlord, without any setoff or deduction, unless
expressly set forth in this Lease, all Base Rent and Additional Rent due for the
Term (collectively referred to as "RENT"). "ADDITIONAL RENT" means all sums
(exclusive of Base Rent) that Tenant is required to pay Landlord under this
Lease. Tenant shall pay and be liable for all rental, sales and use taxes (but
excluding income taxes), if any, imposed upon or measured by Rent. Base Rent and
recurring monthly charges of Additional Rent shall be due and payable in advance
on the first day of each calendar month without notice or demand, provided that
the installment of Base Rent for the seventh full calendar month of the Term,
and the first monthly installment of Additional Rent for Expenses and Taxes,
shall be payable upon the execution of this Lease by Tenant. All other items of
Rent shall be due and payable by Tenant on or before 30 days after billing by
Landlord. Rent shall be made payable to the entity, and sent to the address,
Landlord designates and shall be made by good and sufficient check or by other
means acceptable to Landlord. Tenant shall pay Landlord an administration fee
equal to 5% of all past due Rent, provided that Tenant shall be entitled to a
grace period of 5 days for the first 2 late payments of Rent in a calendar year.
In addition, past due Rent shall accrue interest at 12% per annum. Landlord's
acceptance of less than the correct amount of Rent shall be considered a payment
on account of the earliest Rent due. Rent for any partial month during the Term
shall be prorated. No endorsement or statement on a check or letter accompanying
payment shall be considered an accord and satisfaction. Tenant's covenant to pay
Rent is independent of every other covenant in this Lease.

     4.02 Tenant shall pay Tenant's Pro Rata Share of Taxes and Expenses in
accordance with EXHIBIT B of this Lease.

5.   COMPLIANCE WITH LAWS; USE.

     The Premises shall be used for the Permitted Use and for no other use

rules and regulations of any municipal or governmental entity whether in effect
now or later, including the Americans with Disabilities Act ("LAW(S)"),
regarding the operation of Tenant's business and the use, condition,
configuration and occupancy of the Premises. In addition, Tenant shall, at its
sole cost and expense, promptly comply with any Laws that relate to the "Base
Building" (defined below), but only to the extent such obligations are triggered
by Tenant's use of the Premises, other than for general office use, or
Alterations or improvements in the Premises performed or requested by Tenant.

public restrooms and the Building mechanical, electrical and plumbing systems

governmental agencies that the Building is in violation of either applicable

6.   SECURITY DEPOSIT.

     The Security Deposit shall be delivered to Landlord upon the execution of
this Lease by Tenant and held by Landlord without liability for interest (unless
required by Law) as security for the performance of Tenant's obligations. The
Security Deposit is not an advance payment of Rent or a measure of damages.
Landlord may use all or a portion of the Security Deposit to satisfy past due
Rent or to cure any Default (defined in Section 18) by Tenant, or to satisfy any
other loss or damage resulting from Tenant's Default as provided in Section 19.
If Landlord uses any portion of the Security Deposit, Tenant shall, within 5

7.   BUILDING SERVICES.

     7.01 Landlord shall furnish Tenant with the following services: (a) water
for use in the Base Building lavatories; (b) customary heat and air conditioning
in season during Building Service Hours, although Tenant shall have the right to
receive HVAC service during hours other than Building Service Hours by paying
Landlord's then standard charge for additional HVAC service and providing such
prior notice as is reasonably specified by Landlord; (c) standard janitorial
service on Business Days; (d) elevator service; (e) electricity in accordance
with the terms and conditions in Section 7.02; (f) access to the Building for

services as Landlord reasonably determines are necessary or appropriate for the
Property.

     7.02 Electricity used by Tenant in the Premises shall, at Landlord's
option, be paid for by Tenant either: (a) through inclusion in Expenses (except
as provided for excess usage); (b) by a separate charge payable by Tenant to
Landlord; or (c) by separate charge billed by the applicable utility company and
payable directly by Tenant. Without the consent of Landlord, Tenant's use of
electrical service shall not exceed, either in voltage, rated capacity, use
beyond Building Service Hours or overall load, that which Landlord reasonably
deems to be standard for the Building. Landlord shall have the right to measure
electrical usage by commonly accepted methods, including the installation of
measuring devices such as submeters and check meters. If it is determined that
Tenant is using excess electricity, Tenant shall pay Landlord Additional Rent
for the cost of such excess electrical usage and for the cost of purchasing and
installing the measuring device(s).

     7.03 Landlord's failure to furnish, or any interruption, diminishment or
termination of services due to the application of Laws, the failure of any
equipment, the performance of repairs, improvements or alterations, utility
interruptions or the occurrence of an event of Force Majeure (defined in Section
26.03) (collectively a "SERVICE FAILURE") shall not render Landlord liable to
Tenant, constitute a constructive eviction of Tenant, give rise to an abatement
of Rent,


                                       5

<PAGE>

nor relieve Tenant from the obligation to fulfill any covenant or agreement.
However, if the Premises, or a material portion of the Premises, are made
untenantable for a period in excess of 2 consecutive Business Days as a result
of a Service Failure that is reasonably within the control of Landlord to
correct, then Tenant, as its sole remedy, shall be entitled to receive an
abatement of Rent payable hereunder during the period beginning on the 4th
consecutive Business Day of the Service Failure and ending on the day the
service has been restored. If the entire Premises have not been rendered
untenantable by the Service Failure, the amount of abatement shall be equitably
prorated.

8.   LEASEHOLD IMPROVEMENTS.

     All improvements in and to the Premises, including any Alterations (defined
in Section 9.03) (collectively, "LEASEHOLD IMPROVEMENTS") shall remain upon the
Premises at the end of the Term without compensation to Tenant, provided that
Tenant, at its expense, in compliance with the National Electric Code or other
applicable Law, shall remove any Cable (defined in Section 9.01 below). In
addition, Landlord, by written notice to Tenant within 30 days prior to the
Termination Date, may require Tenant, at its expense, to remove any Landlord
Work or Alterations that, in Landlord's reasonable judgment, are of a nature
that would require removal and repair costs that are materially in excess of the
removal and repair costs associated with standard office improvements (the Cable
and such other items collectively are referred to as "REQUIRED REMOVABLES").
Required Removables shall include, without limitation, internal stairways,
raised floors, personal baths and showers, vaults, rolling file systems and
structural alterations and modifications. The Required Removables shall be
removed by Tenant before the Termination Date. Tenant shall repair damage caused
by the installation or removal of Required Removables. If Tenant fails to
perform its obligations in a timely manner, Landlord may perform such work at
Tenant's expense. Tenant, at the time it requests approval for a proposed
Alteration, including any Initial Alterations or Landlord Work, as such terms
may be defined in the Work Letter attached as EXHIBIT C, may request in writing
that Landlord advise Tenant whether the Alteration, including any Initial
Alterations or Landlord Work, or any portion thereof, is a Required Removable.
Within 10 days after receipt of Tenant's request, Landlord shall advise Tenant
in writing as to which portions of the alteration or other improvements are
Required Removables. Notwithstanding the foregoing (except for Cable (if any)
and/or any electrical panels/transformers and any above Building standard
electrical outlets and hook-ups), no portion of the Landlord Work (which
Landlord Work shall be mutually agreed upon and depicted in the Plans (as
hereinafter defined)) shall be deemed a Required Removable.

9.   REPAIRS AND ALTERATIONS.

     9.01 Tenant shall periodically inspect the Premises to identify any
conditions that are dangerous or in need of maintenance or repair. Tenant shall
promptly provide Landlord with notice of any such conditions. Tenant shall, at
its sole cost and expense, perform all maintenance and repairs to the Premises
that are not Landlord's express responsibility under this Lease, and keep the
Premises in good condition and repair, reasonable wear and tear excepted.
Tenant's repair and maintenance obligations include, without limitation, repairs
to: (a) floor covering; (b) interior partitions; (c) doors; (d) the interior

the acts of Tenant, Tenant Related Parties and their respective contractors and
vendors. If Tenant fails to make any repairs to the Premises for more than 15
days after notice from Landlord (although notice shall not be required in an
emergency), Landlord may make the repairs, and Tenant shall pay the reasonable
cost of the repairs, together with an administrative charge in an amount equal
to 7% of the cost of the repairs.

     9.03 Tenant shall not make alterations, repairs, additions or improvements
or install any Cable (collectively referred to as "ALTERATIONS") without first
obtaining the written consent of Landlord in each instance, which consent shall
not be unreasonably withheld or delayed, However, Landlord's consent shall not
be required for any Alteration that satisfies all of the following criteria (a
"COSMETIC ALTERATION"): (a) is of a cosmetic nature such as painting,
wallpapering, hanging pictures and installing carpeting; (b) is not visible from
the exterior of the Premises or Building; (c) will not affect the Base Building;
(d) does not require work to be performed inside the walls or above the ceiling
of the Premises, and (e) costs no more than $20,000.00 to perform. Cosmetic
Alterations shall be subject to all the other provisions of this Section 9.03.
Prior to starting work, Tenant shall furnish Landlord with plans and
specifications; names of contractors reasonably acceptable to Landlord (provided
that Landlord may designate specific contractors with respect to Base Building);
required permits and approvals; evidence of contractor's and subcontractor's
insurance in amounts reasonably required by Landlord and naming Landlord as an
additional insured; and any security for performance in amounts reasonably
required by Landlord. Changes to the plans and specifications must also be
submitted to Landlord for its approval. Alterations shall be constructed in a
good and workmanlike manner using materials of a quality reasonably approved by
Landlord. Tenant shall reimburse Landlord for any sums paid by Landlord for
third party examination of Tenant's plans for non-Cosmetic Alterations. In
addition, Tenant shall pay Landlord A fee for Landlord's oversight and
coordination of any non-Cosmetic Alterations equal to 5% of the cost of the
non-Cosmetic Alterations. Upon completion, Tenant shall furnish "as-built" plans
for non-Cosmetic Alterations, completion affidavits and full and final waivers
of lien, Landlord's approval of an Alteration shall not be deemed a
representation by Landlord that the Alteration complies with Law.

10.  ENTRY BY LANDLORD.

     Landlord may enter the Premises to inspect, show or clean the Premises or
to perform or facilitate the performance of repairs, alterations or additions to
the Premises or any portion of the Building. Except in emergencies or to provide
Building services, Landlord shall provide Tenant with reasonable prior verbal
notice of entry and shall use reasonable efforts to minimize any interference
with Tenant's use of the Premises. If reasonably necessary, Landlord may
temporarily close all or a portion of the Premises to perform repairs,
alterations and additions. However, except in emergencies, Landlord will not
close the Premises if the work can reasonably be completed on weekends and after
Building Service Hours. Entry by Landlord in compliance with this Section shall
not constitute a constructive eviction or entitle Tenant to an abatement or
reduction of Rent.

11.  ASSIGNMENT AND SUBLETTING.

     11.01 Except in connection with a Business Transfer (defined in Section
11.04), Tenant shall not assign, sublease, transfer or encumber any interest in
this Lease or allow any third party to use any portion of the Premises
(collectively or individually, a "TRANSFER") without the prior written consent
of Landlord, which consent shall not be unreasonably withheld, conditioned or
delayed if Landlord does not exercise its recapture rights under Section 11.02.
If the entity(ies) which directly or indirectly controls the voting
shares/rights of Tenant changes at any time, such change of ownership or control
shall constitute a Transfer unless Tenant is an entity whose outstanding stock
is listed on a recognized securities exchange or if at least 80% of its voting
stock is owned by another entity, the voting stock of which is so listed. Tenant
hereby waives the provisions of Section 1995.310 of the California Civil Code,
or any similar or successor Laws, now or hereinafter in effect, and all other
remedies, including, without limitation, any right at law or equity to terminate
this Lease, on its own behalf and, to the extent permitted under all applicable
Laws, on behalf of the proposed transferee. Any Transfer in violation of this
Section shall, at Landlord's option, be deemed a Default by Tenant as described
in Section 18, and shall be voidable by Landlord. In no event shall any
Transfer, including a Business Transfer, release or relieve Tenant from any
obligation under this Lease, and Tenant shall remain primarily liable far the
performance of the tenant's obligations under this Lease, as amended from time
to time.

     11.02 Tenant shall provide Landlord with financial statements for the
proposed transferee, a fully executed copy of the proposed assignment, sublease
or other Transfer documentation and such other information as Landlord may
reasonably request. Within 15 Business Days after receipt of the required
information and documentation, Landlord shall either: (a) consent to the
Transfer by execution of a consent agreement in a form reasonably designated by
Landlord; (b) reasonably refuse to consent to the Transfer in writing; or (c) in
the event of an assignment of this Lease or subletting of more than 20% of the
Rentable Square Footage of the Premises for more than 50% of the remaining Term
(excluding unexercised options), recapture the


                                       7

<PAGE>

portion of the Premises that Tenant is proposing to Transfer (other than
pursuant to a Business Transfer). If Landlord exercises its right to recapture,
this Lease shall automatically be amended (or terminated if the entire Premises
is being assigned or sublet) to delete the applicable portion of the Premises
effective on the proposed effective date of the Transfer, although Landlord may
require Tenant to execute a reasonable amendment or other document reflecting
such reduction or termination. Tenant shall pay Landlord a review fee of
$1,500.00 for Landlord's review of any requested Transfer.

     11.03 Tenant shall pay Landlord 50% of all rent and other consideration
which Tenant receives as a result of a Transfer that is in excess of the Rent
payable to Landlord for the portion of the Premises and Term covered by the
Transfer. Tenant shall pay Landlord for Landlord's share of the excess within 30
days after Tenant's receipt of the excess. Tenant may deduct from the excess, on
a straight-line basis, all reasonable and customary expenses directly incurred
by Tenant attributable to the Transfer. If Tenant is in Default, Landlord may
require that all sublease payments be made directly to Landlord, in which case
Tenant shall receive a credit against Rent in the amount of Tenant's share of
payments received by Landlord.

     11.04 Tenant may assign this Lease to a successor to Tenant by merger,
consolidation or the purchase of substantially all of Tenant's assets, or assign
this Lease or sublet all or a portion of the Premises to an Affiliate (defined
below), without the consent of Landlord, provided that all of the following
conditions are satisfied (a "BUSINESS TRANSFER"); (a) Tenant must not be in
Default; (b) Tenant must give Landlord written notice at least 15 Business Days
before such Transfer; and (c) if such Transfer will result from a merger or
consolidation of Tenant with another entity, then the Credit Requirement
(defined below) must be satisfied. Tenant's notice to Landlord shall include
information and documentation evidencing the Business Transfer and showing that
each of the above conditions has been satisfied. If requested by Landlord,
Tenant's successor shall sign a commercially reasonable form of assumption
agreement. "AFFILIATE" shall mean an entity controlled by, controlling or under
common control with Tenant. The "CREDIT REQUIREMENT" shall be deemed satisfied
if, as of the date immediately preceding the date of the Transfer, the financial
strength of the entity with which Tenant is to merge or consolidate is not less
than that of Tenant, as determined (x) based on credit ratings of such entity
and Tenant by both Moody's and Standard & Poor's (or by either such agency alone
if applicable ratings by the other agency do not exist), or (y) if such credit
ratings do not exist, then in accordance with Moody's KMV RiskCalc (i.e., the
on-line software tool offered by Moody's for analyzing credit risk) based on
CFO-certified financial statements for such entity and Tenant covering their
last two fiscal years ending before the Transfer.

12.  LIENS.

     Tenant shall not permit mechanics' or other liens to be placed upon the
Property, Premises or Tenant's leasehold interest in connection with any work or
service done or purportedly done by or for the benefit of Tenant or its
transferees. Tenant shall give Landlord notice at least 15 days prior to the
commencement of any work in the Premises to afford Landlord the opportunity,
where applicable, to post and record notices of non-responsibility. Tenant,
within 10 days of notice from Landlord, shall fully discharge any lien by
settlement, by bonding or by insuring over the lien in the manner prescribed by
the applicable lien Law and, if Tenant fails to do so, Tenant shall be deemed in
Default under this Lease and, in addition to any other remedies available to
Landlord as a result of such Default by Tenant, Landlord, at its option, may
bond, insure over or otherwise discharge the lien. Tenant shall reimburse
Landlord for any amount paid by Landlord, including, without limitation,
reasonable attorneys' fees.

13.  INDEMNITY AND WAIVER OF CLAIMS.

     Except to the extent caused by the negligence or willful misconduct of
Landlord or any Landlord Related Parties (defined below), Tenant shall
indemnify, defend and hold Landlord and Landlord Related Parties harmless
against and from all liabilities, obligations, damages, penalties, claims,
actions, costs, charges and expenses, including, without, limitation, reasonable
attorneys' fees and other professional fees (if and to the extent permitted by
Law) (collectively referred to as "LOSSES"), which may be imposed upon, incurred
by or asserted against Landlord or any of the Landlord Related Parties by any
third party and arising out of or in connection with any damage or injury
occurring in the Premises or any acts or omissions (including violations of Law)
of Tenant, the Tenant Related Parties (defined below) or any of Tenant's
transferees, contractors or licensees. Except to the extent caused by the
negligence or willful misconduct of Tenant or any Tenant Related Parties,
Landlord shall indemnify, defend and hold Tenant, its trustees, members,
principals, beneficiaries, partners, officers, directors, employees and agents
("TENANT RELATED PARTIES") harmless against and from all Losses which


                                       8

<PAGE>

may be imposed upon, incurred by or asserted against Tenant or any of the Tenant
Related Parties by any third party and arising out of or in connection with the
acts or omissions (including violations of Law) of Landlord or the Landlord
Related Parties. Tenant hereby waives all claims against and releases Landlord
and its trustees, members, principals, beneficiaries, partners, officers,
directors, employees, Mortgagees (defined in Section 23) and agents (the
"LANDLORD RELATED PARTIES") from all claims for any injury to or death of
persons, damage to property or business loss in any manner related to (a) Force
Majeure, (b) acts of third parties, (c) the bursting or leaking of any tank,
water closet, drain or other pipe, (d) the inadequacy or failure of any security
or protective services, personnel or equipment, or (e) any matter not within the
reasonable control of Landlord.

14.  INSURANCE.

     Tenant shall maintain the following insurance ("TENANT'S INSURANCE"): (a)
Commercial General Liability Insurance applicable to the Premises and its
appurtenances providing, on an occurrence basis, a minimum combined single limit
of $2,000,000.00; (b) Property/Business Interruption Insurance written on an All
Risk or Special Cause of Loss Form, including earthquake sprinkler leakage, at
replacement cost value and with a replacement cost endorsement covering all of
Tenant's business and trade fixtures, equipment, movable partitions, furniture,

PROPERTY") and any Leasehold Improvements performed by or for the benefit of
Tenant; (c) Workers' Compensation Insurance in amounts required by Law; and (d)
Employers Liability Coverage of at least $1,000,000.00 per occurrence. Any
company writing Tenant's Insurance shall have an A.M. Best rating of not less

additional insureds Landlord (or its successors and assignees), the managing
agent for the Building (or any successor), EOP Operating Limited Partnership,
Equity Office Properties Trust and their respective members, principals,
beneficiaries, partners, officers, directors, employees, and agents, and other
designees of Landlord and its successors as the interest of such designees shall
appear. In addition, Landlord shall be named as a loss payee with respect to
Property/Business Interruption Insurance on the Leasehold Improvements. All
policies of Tenant's Insurance shall contain endorsements that the insurer(s)
shall give Landlord and its designees at least 30 days' advance written notice
of any cancellation, termination, material change or lapse of insurance. Tenant
shall provide Landlord with a certificate of insurance evidencing Tenant's
Insurance prior to the earlier to occur of the Commencement Date or the date
Tenant is provided with possession of the Premises, and thereafter as necessary
to assure that Landlord always has current certificates evidencing Tenant's
Insurance. So long as the same is available at commercially reasonable rates,
Landlord shall maintain so called All Risk property insurance on the Building at
replacement cost value as reasonably estimated by Landlord, together with such
other insurance coverage as Landlord, in its reasonable judgment, may elect to
maintain.

15.  SUBROGATION.

     Landlord and Tenant hereby waive and shall cause their respective insurance
carriers to waive any and all rights of recovery, claims, actions or causes of
action against the other for any loss or damage with respect to Tenant's
Property, Leasehold Improvements, the Building, the Premises, or any contents
thereof, including rights, claims, actions and causes of action based on
negligence, which loss or damage is (or would have been, had the insurance
required by this Lease been carried) covered by insurance. For the purposes of
this waiver, any deductible with respect to a party's insurance shall be deemed
covered by and recoverable by such party under valid and collectable policies of
insurance.

16.  CASUALTY DAMAGE.

     16.01 If all or any portion of the Premises becomes untenantable by fire or
other casualty to the Premises (collectively a "CASUALTY"), Landlord, with
reasonable promptness, shall cause a general contractor selected by Landlord to
provide Landlord and Tenant with a written estimate of the amount of time
required using standard working methods to Substantially Complete the repair and
restoration of the Premises and any Common Areas necessary to provide access to
the Premises ("COMPLETION ESTIMATE"). If the Completion Estimate indicates that
the Premises or any Common Areas necessary to provide access to the Premises
cannot be made tenantable within 270 days from the date the repair is started,
then either party shall have the right to terminate this Lease upon written
notice to the other within 10 days after receipt of the Completion Estimate.
Tenant, however, shall not have the right to terminate this Lease if the
Casualty was caused by the negligence or intentional misconduct of Tenant or any
Tenant Related Parties. In addition, Landlord, by notice to Tenant within 90
days after the date of the Casualty, shall have the right to terminate this
Lease if: (1) the Premises have been materially


                                       9

<PAGE>

damaged and there is less than 2 years of the Term remaining on the date of the
Casualty; (2) any Mortgagee requires that the insurance proceeds be applied to
the payment of the mortgage debt; or (3) a material uninsured loss to the
Building or Premises occurs. In addition, Tenant shall have the right to
terminate this Lease if: (1) (a) a substantial portion of the Premises has been
damaged by fire or other Casualty and such damage cannot reasonably be repaired
within 60 days after the Casualty; (b) there is less than 1 year of the Term
remaining on the date of such Casualty; (c) the Casualty was not caused by the
negligence or willful misconduct of Tenant or its agents, employees or
contractors; and (d) Tenant provides Landlord with written notice of its intent
to terminate within 30 days after the date of the fire or other Casualty and/or
(2)(a) a substantial portion of the Premises has been damaged by fire or other
Casualty and the repair or restoration is not Substantially Complete on or
before the Required Completion Date (defined below), (b) the Casualty was not
caused by the negligence or willful misconduct of Tenant or its agents,
employees or contractors and (c) Tenant provides Landlord with written notice of
its intent to terminate before the earlier to occur of: (i) 5 Business Days
after the Required Completion Date; and (ii) the date such repair or restoration
is Substantially Complete. The "REQUIRED COMPLETION DATE" shall mean the date
which is 60 days after the stated estimated completion date as set forth in the
Completion Estimate. Landlord and Tenant acknowledge and agree that: (i) the
determination of the date upon which the repair and restoration work is
Substantially Complete shall take into consideration the effect of any Tenant
Delays; and (ii) the Required Completion Date shall be postponed by the number
of days the repair and restoration work is delayed due to events of Force
Majeure. Notwithstanding any provision herein to the contrary, if Landlord
determines in good faith that it will be unable to cause the repair or
restoration work be Substantially Complete by the Required Completion Date,
Landlord shall have the right to immediately cease its performance of the repair
and restoration work and provide Tenant with written notice (the "COMPLETION
DATE EXTENSION NOTICE") of such inability, which Completion Date Extension
Notice shall set forth the date on which Landlord reasonably believes that the
repair and restoration work will be Substantially Complete. Upon receipt of the
Completion Date Extension Notice, Tenant shall have the right to terminate this
Lease by providing written notice of termination to Landlord within 5 Business
Days after the date of the Completion Date Extension Notice. If Tenant does not
terminate this Lease within such 5 Business Day period, the Required Completion
Date automatically shall be amended to be the date set forth in Landlord's
Completion Date Extension Notice.

     16.02 If this Lease is not terminated, Landlord shall promptly and
diligently, subject to reasonable delays for insurance adjustment or other
matters beyond Landlord's reasonable control, restore the Premises, Common Areas
and Leasehold Improvements to substantially the same condition they were in
immediately before the Casualty (but excluding any Alterations that were
performed by Tenant in violation of this Lease). Such restoration shall be to
substantially the same condition that existed prior to the Casualty, except for
modifications required by Law or any other modifications to the Common Areas
deemed desirable by Landlord. Upon notice from Landlord, Tenant shall assign or
endorse over to Landlord (or to any party designated by Landlord) all property
insurance proceeds payable to Tenant under Tenant's Insurance with respect to
any Leasehold Improvements performed by or for the benefit of Tenant; provided
if the estimated cost to repair such Leasehold Improvements exceeds the amount
of Insurance proceeds received by Landlord from Tenant's insurance carrier, the
excess cost of such repairs shall be paid by Tenant to Landlord prior to
Landlord's commencement of repairs. Within 15 days of demand, Tenant shall also
pay Landlord for any additional excess costs that are determined during the
performance of the repairs. In no event shall Landlord be required to spend more
for the restoration than the proceeds received by Landlord, whether insurance
proceeds or proceeds from Tenant. If, at any time after the Casualty, (a)
Landlord is unable to obtain all or any portion of the insurance proceeds from
Landlord's insurance, (b) in restoring the Premises and/or the Common Areas
providing access to the Premises, Landlord chooses not to spend more than the
restoration proceeds received by Landlord, and (c) Landlord provides Tenant
written notice of the same (which Landlord shall be obligated to deliver within
30 days of making such determination), then within 30 days of the date thereof
and by written notice to Landlord, Tenant shall have the right to terminate this
Lease if the Casualty was not caused by the negligence or intentional misconduct
of Tenant or any Tenant Related Parties. Landlord shall not be liable for any
inconvenience to Tenant, or injury to Tenant's business resulting in any way
from the Casualty or the repair thereof. Provided that Tenant is not in Default,
during any period of time that all or a material portion of the Premises is
rendered untenantable as a result of a Casualty, the Rent shall abate for the
portion of the Premises that is untenantable and not used by Tenant.

     16.03 If Tenant was entitled to but elected not to exercise its right to
terminate the Lease and Landlord does not substantially complete the repair and
restoration of the Premises within 2 months after the expiration of the
estimated period of time set forth in the Completion


                                       10

<PAGE>

Estimate, which period shall be extended to the extent of any Reconstruction
Delays (defined below), then Tenant may terminate this Lease by written notice
to Landlord within 15 days after the expiration of such period, as the same may
be extended. For purposes of this Lease, the term "RECONSTRUCTION DELAYS" shall
mean: (i) any delays caused by the insurance adjustment process; (ii) any delays
caused by Tenant; and (iii) any delays caused by events of Force Majeure.

     16.04 The provisions of this Lease, including this Section 16, constitute
an express agreement between Landlord and Tenant with respect to any and all
damage to, or destruction of, all or any part of the Premises or the Property,
and any Laws, including, without limitation, Sections 1932(2) and 1933(4) of the
California Civil Code, with respect to any rights or obligations concerning
damage or destruction in the absence of an express agreement between the
parties, and any similar or successor Laws now or hereinafter in effect, shall
have no application to this Lease or any damage or destruction to all or any
part of the Premises or the Property.

17.  CONDEMNATION.

     Either party may terminate this Lease if any material part of the Premises
is taken or condemned for any public or quasi-public use under Law, by eminent
domain or private purchase in lieu thereof (a "TAKING"). Landlord shall also
have the right to terminate this Lease if there is a Taking of any portion of
the Building or Property which would have a material adverse effect on
Landlord's ability to profitably operate the remainder of the Building. The
terminating party shall provide written notice of termination to the other party
within 45 days after it first receives notice of the Taking. The termination
shall be effective as of the effective date of any order granting possession to,
or vesting legal title in, the condemning authority. If this Lease is not
terminated, Base Rent and Tenant's Pro Rata Share shall be appropriately
adjusted to account for any reduction in the square footage of the Building or
Premises. All compensation awarded for a Taking shall be the property of
Landlord. The right to receive compensation or proceeds are expressly waived by
Tenant, however, Tenant may file a separate claim for Tenant's Property and
Tenant's reasonable relocation expenses, provided the filing of the claim does
not diminish the amount of Landlord's award. If only a part of the Premises is
subject to a Taking and this Lease is not terminated, Landlord, with reasonable
diligence, will restore the remaining portion of the Premises as nearly as
practicable to the condition immediately prior to the Taking. Tenant hereby
waives any and all rights it might otherwise have pursuant to Section 1265.130
of the California Code of Civil Procedure, or any similar or successor Laws.

18.  EVENTS OF DEFAULT.

     In addition to any other default specifically described in this Lease, each
of the following occurrences shall be a "DEFAULT": (a) Tenant's failure to pay
any portion of Rent when due, if the failure continues for 3 days after written
notice to Tenant ("MONETARY DEFAULT"); (b) Tenant's failure (other than a
Monetary Default) to comply with any term, provision, condition or covenant of
this Lease, if the failure is not cured within 10 days after written notice to
Tenant provided, however, if Tenant's failure to comply cannot reasonably be
cured within 10 days, Tenant shall be allowed additional time (not to exceed 60
days) as is reasonably necessary to cure the failure so long as Tenant begins
the cure within 10 days and diligently pursues the cure to completion; (c)
Tenant permits a Transfer without Landlord's required approval or otherwise in
violation of Section 11 of this Lease; (d) Tenant or any Guarantor becomes
insolvent, makes a transfer in fraud of creditors, makes an assignment for the
benefit of creditors, admits in writing its inability to pay its debts when due
or forfeits or loses its right to conduct business; (e) the leasehold estate is
taken by process or operation of Law; (f) in the case of any ground floor or
retail Tenant, Tenant does not lake possession of or abandons or vacates all or
any portion of the Premises; or (g) Tenant is in default beyond any notice and
cure period under any other lease or agreement with Landlord at the Building or
Property. If Landlord provides Tenant with notice of Tenant's failure to comply
with any specific provision of this Lease on 3 separate occasions during any 12
month period, Tenant's subsequent violation of such provision shall, at
Landlord's option, be an incurable Default by Tenant. All notices sent under
this Section shall be in satisfaction of, and not in addition to, notice
required by Law.

19.  REMEDIES.

     19.01 Upon the occurrence of any Default under this Lease, whether
enumerated in Section 18 or not, Landlord shall have the option to pursue any
one or more of the following remedies without any notice (except as expressly
prescribed herein) or demand whatsoever (and without limiting the generality of
the foregoing, Tenant hereby specifically waives notice and


                                       11

<PAGE>

demand for payment of Rent or other obligations, except for those notices
specifically required pursuant to the terms of Section 18 or this Section 19,
and waives any and all other notices or demand requirements imposed by
applicable law):

     (a)  Terminate this Lease and Tenant's right to possession of the Premises
          and recover from Tenant an award of damages equal to the sum of the
          following:

          (i)  The Worth at the Time of Award of the unpaid Rent which had been
               earned at the time of termination;

          (ii) The Worth at the Time of Award of the amount by which the unpaid
               Rent which would have been earned after termination until the
               time of award exceeds the amount of such Rent loss that Tenant
               affirmatively proves could have been reasonably avoided;

          (iii) The Worth at the Time of Award of the amount by which the unpaid
               Rent for the balance of the Term after the time of award exceeds
               the amount of such Rent loss that Tenant affirmatively proves
               could be reasonably avoided;

          (iv) Any other amount necessary to compensate Landlord for all the
               detriment either 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;
               and

          (v)  All such other amounts in addition to or in lieu of the foregoing
               as may be permitted from time to time under applicable law.

          The "WORTH AT THE TIME OF AWARD" of the amounts referred to in parts
          (i) and (ii) above, shall be computed by allowing interest at the
          lesser of a per annum rate equal to: (A) the greatest per annum rate
          of Interest permitted from time to time under applicable law, or (B)
          the Prime Rate plus 5%. For purposes hereof, the "PRIME RATE" shall be
          the per annum interest rate publicly announced as its prime or base
          rate by a federally insured bank selected by Landlord in the State of
          California. The "WORTH AT THE TIME OF AWARD" of the amount referred to
          in part (iii), above, shall be computed by discounting such amount at
          the discount rate of the Federal Reserve Bank of San Francisco at the
          time of award plus 1%;

     (b)  Employ the remedy described in California Civil Code Section 1951.4
          (Landlord may continue this Lease in effect after Tenant's breach and
          abandonment and recover Rent as it becomes due, if Tenant has the
          right to sublet or assign, subject only to reasonable limitations); or

     (c)  Notwithstanding Landlord's exercise of the remedy described in
          California Civil Code Section 1951.4 in respect of an event or events
          of default, at such time thereafter as Landlord may elect in writing,
          to terminate this Lease and Tenant's right to possession of the
          Premises and recover an award of damages as provided above in
          Paragraph 19.01 (a).

     19.02 The subsequent acceptance of Rent hereunder by Landlord shall not be
deemed to be a waiver of any preceding breach by Tenant of any term, covenant or
condition of this Lease, other than the failure of Tenant to pay the particular
Rent so accepted, regardless of Landlord's knowledge of such preceding breach at
the time of acceptance of such Rent. No waiver by Landlord of any breach hereof
shall be effective unless such waiver is in writing and signed by Landlord.

     19.03 TENANT HEREBY WAIVES ANY AND ALL RIGHTS CONFERRED BY SECTION 3275 OF
THE CIVIL CODE OF CALIFORNIA AND BY SECTIONS 1174 (c) AND 1179 OF THE CODE OF
CIVIL PROCEDURE OF CALIFORNIA AND ANY AND ALL OTHER LAWS AND RULES OF LAW FROM
TIME TO TIME IN EFFECT DURING THE LEASE TERM PROVIDING THAT TENANT SHALL HAVE
ANY RIGHT TO REDEEM, REINSTATE OR RESTORE THIS LEASE FOLLOWING ITS TERMINATION
BY REASON OF TENANT'S BREACH. TENANT ALSO HEREBY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY LAW, THE RIGHT TO TRIAL BY JURY IN ANY LITIGATION ARISING OUT OF OR
RELATING TO THIS LEASE.

     19.04 No right or remedy herein conferred upon or reserved to Landlord is
intended to be exclusive of any other right or remedy, and each and every right
and remedy shall be cumulative and in addition to any other right or remedy
given hereunder or now or hereafter existing by agreement, applicable law or in
equity. In addition to other remedies provided in this Lease, Landlord shall be
entitled, to the extent permitted by applicable law, to injunctive relief, or to
a decree compelling performance of any of the covenants, agreements, conditions
or provisions of this Lease, or to any other remedy allowed to Landlord at law
or in equity. Forbearance by Landlord to enforce one or more of the remedies
herein provided upon an event of default shall not be deemed or construed to
constitute a waiver of such default.

     19.05 If Tenant is in Default of any of its non-monetary obligations under
the Lease, Landlord shall have the right to perform such obligations. Tenant
shall reimburse Landlord for the cost of such performance upon demand together
with an administrative charge equal to 10% of the cost of the work performed by
Landlord.

     19.06 This Section 19 shall be enforceable to the maximum extent such
enforcement is not prohibited by applicable law, and the unenforceability of any
portion thereof shall not thereby render unenforceable any other portion.

20.  LIMITATION OF LIABILITY.

     NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS LEASE, THE
LIABILITY OF LANDLORD (AND OF ANY SUCCESSOR LANDLORD) SHALL BE LIMITED TO THE
LESSER OF (A) THE INTEREST OF LANDLORD IN THE PROPERTY, OR (B) THE EQUITY
INTEREST LANDLORD WOULD HAVE IN THE PROPERTY IF THE PROPERTY WERE ENCUMBERED BY
THIRD PARTY DEBT IN AN AMOUNT EQUAL TO 70% OF THE VALUE OF THE PROPERTY. TENANT
SHALL LOOK SOLELY TO LANDLORD'S INTEREST IN THE PROPERTY FOR THE RECOVERY OF ANY
JUDGMENT OR AWARD AGAINST LANDLORD OR ANY LANDLORD RELATED PARTY. NEITHER
LANDLORD NOR ANY LANDLORD RELATED PARTY SHALL BE PERSONALLY LIABLE FOR ANY
JUDGMENT OR DEFICIENCY, AND IN NO EVENT SHALL LANDLORD OR ANY LANDLORD RELATED
PARTY BE LIABLE TO TENANT FOR ANY LOST PROFIT, DAMAGE TO OR LOSS OF BUSINESS OR
ANY FORM OF SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGE. BEFORE FILING SUIT FOR AN
ALLEGED DEFAULT BY LANDLORD, TENANT SHALL GIVE LANDLORD AND THE MORTGAGEE(S)
WHOM TENANT HAS BEEN NOTIFIED HOLD MORTGAGES (DEFINED IN SECTION 23 BELOW),
NOTICE AND REASONABLE TIME TO CURE THE ALLEGED DEFAULT.

21.  RELOCATION.

     At Landlord's sole cost and expense, at any time before or during the Term,
if Landlord reasonably determines it is necessary for the health and safety of
Tenant or of other tenants in the Building, Landlord may relocate Tenant from
the Premises to space of reasonably comparable size and utility ("RELOCATION
SPACE") within the Building or adjacent buildings within the same project upon
60 days' prior written notice to Tenant. The Relocation Space must contain
similar finishes as the Premises, and approximately the same Rentable Square
Footage as the Premises and the same number of work stations, offices,
breakrooms and reception areas as are contained in the Premises as of the date
Tenant receives Landlord's notice of relocation. From and after the date of the
relocation, the Base Rent and Tenant's Pro Rata Share shall be adjusted based on
the rentable square footage of the Relocation Space. Landlord shall pay Tenant's
reasonable costs of relocation, including all costs for moving Tenant's
furniture, equipment, supplies and other personal property, as well as the cost
of printing and distributing change of address notices to Tenant's customers and
one month's supply of stationery showing the new address, and prior to such
relocation, Landlord, at Landlord's cost, shall improve the Relocation Space to
incorporate improvements and finishes similar to those incorporated within the
Premises (the commercial availability of like or similar materials shall be
taken into account in such case, so that Landlord will not be required to
duplicate materials or finishes which are no longer readily available on the
market, but may instead, with Tenant's consent [not to be unreasonably withheld,
conditioned or delayed], substitute reasonable replacement materials or
finishes). Landlord shall also reimburse Tenant for the reasonable cost to
install and connect telecommunication and data cabling in the Relocation Space
in the manner and to the extent such cabling existed in the Premises prior to
the relocation.

<PAGE>

22.  HOLDING OVER.

     If Tenant fails to surrender all or any part of the Premises at the
termination of this Lease, occupancy of the Premises after termination shall be
that of a tenancy at sufferance. Tenant's occupancy shall be subject to all the
terms and provisions of this Lease, and Tenant shall pay an amount (on a per
month basis without reduction for partial months during the holdover) equal to
125% of the sum of the Base Rent and Additional Rent due for the period
immediately preceding the holdover. Notwithstanding the foregoing, if Tenant's
hold over exceeds three months, then starting in the fourth month, the
percentage in the foregoing sentence shall increase from 125% to 150%. No
holdover by Tenant or payment by Tenant after the termination of this Lease
shall be construed to extend the Term or prevent Landlord from immediate
recovery of possession of the Premises by summary proceedings or otherwise. If
Landlord is unable to deliver possession of the Premises to a new tenant or to
perform improvements for a new tenant as a result of Tenant's holdover and
Tenant fails to vacate the Premises within 15 days after notice from Landlord,
Tenant shall be liable for all damages that Landlord suffers from the holdover.

23.  SUBORDINATION TO MORTGAGES; ESTOPPEL CERTIFICATE.

     Tenant accepts this Lease subject and subordinate to any mortgage(s),
deed(s) of trust, ground lease(s) or other lien(s) now or subsequently arising
upon the Premises, the Building or the Property, and to renewals, modifications,
refinancings and extensions thereof (collectively referred to as a "MORTGAGE").
The party having the benefit of a Mortgage shall be referred to as a
"MORTGAGEE". This clause shall be self-operative, but upon request from a
Mortgagee, Tenant shall execute a commercially reasonable subordination
agreement in favor of the Mortgagee. As an alternative, a Mortgagee shall have
the right at any time to subordinate its Mortgage to this Lease. Upon request,
Tenant, without charge, shall attorn to any successor to Landlord's interest in
this Lease. Landlord and Tenant shall each, within 10 days after receipt of a
written request from the other, execute and deliver a commercially reasonable
estoppel certificate to those parties as are reasonably requested by the other
(including a Mortgagee or prospective purchaser). Without limitation, such
estoppel certificate may include a certification as to the status of this Lease,
the existence of any defaults and the amount of Rent that is due and payable.
Notwithstanding the foregoing in this Article to the contrary, as a condition
precedent to the future subordination of this Lease to a future Mortgage,
Landlord shall be required to provide Tenant with a non-disturbance,
subordination, and attornment agreement in favor of Tenant from any Mortgagee
who comes into existence after the Commencement Date. Such non-disturbance,
subordination, and attornment agreement in favor of Tenant shall provide that,
so long as Tenant is paying the Rent due under the Lease and is not otherwise in
default under the Lease beyond any applicable cure period, its right to
possession and the other terms of the Lease shall remain in full force and
effect. Such non-disturbance, subordination, and attornment agreement may
include other commercially reasonable provisions in favor of the Mortgagee.

24.  NOTICE.

     All demands, approvals, consents or notices (collectively referred to as a
"NOTICE") shall be in writing and delivered by hand or sent by registered or
certified mail with return receipt requested or sent by overnight or same day
courier service at the party's respective Notice Address(es) set forth in
Section 1. Each notice shall be deemed to have been received on the earlier to
occur of actual delivery or the date on which delivery is refused, or, if Tenant
has vacated the Premises or any other Notice Address of Tenant without providing
a new Notice Address, 3 days after notice is deposited in the U.S. mail or with
a courier service in the manner described above. Either party may, at any time,
change its Notice Address (other than to a post office box address) by giving
the other party written notice of the new address.

25.  SURRENDER OF PREMISES.

     At the termination of this Lease or Tenant's right of possession, Tenant
shall remove Tenant's Property from the Premises, and quit and surrender the
Premises to Landlord, broom clean, and in good order, condition and repair,
ordinary wear and tear and damage which Landlord is obligated to repair
hereunder excepted. If Tenant fails to remove any of Tenant's Property within 2
days after termination of this Lease or Tenant's right to possession, Landlord,
at Tenant's sole cost and expense, shall be entitled (but not obligated) to
remove and store Tenant's Property. Landlord shall not be responsible for the
value, preservation or safekeeping of Tenant's Property. Tenant shall pay
Landlord, upon demand, the expenses and storage charges incurred. If Tenant
fails to remove Tenant's Property from the Premises or storage,


                                       14

<PAGE>

within 30 days after notice, Landlord may deem all or any part of Tenant's
Property to be abandoned and title to Tenant's Property shall vest in Landlord.

26.  MISCELLANEOUS.

     26.01 This Lease shall be interpreted and enforced in accordance with the
Laws of the state or commonwealth in which the Building is located and Landlord
and Tenant hereby irrevocably consent to the jurisdiction and proper venue of
such state or commonwealth. If any term or provision of this Lease shall to any
extent be void or unenforceable, the remainder of this Lease shall not be
affected. If there is more than one Tenant or if Tenant is comprised of more
than one party or entity, the obligations imposed upon Tenant shall be joint and
several obligations of all the parties and entities, and requests or demands
from any one person or entity comprising Tenant shall be deemed to have been
made by all such persons or entities. Notices to any one person or entity shall
be deemed to have been given to all persons and entities. Tenant represents and
warrants to Landlord that each individual executing this Lease on behalf of
Tenant is authorized to do so on behalf of Tenant and that Tenant is not, and
the entities or individuals constituting Tenant or which may own or control
Tenant or which may be owned or controlled by Tenant are not, (i) in violation
of any laws relating to terrorism or money laundering, or (ii) among the
individuals or entities identified on any list compiled pursuant to Executive
Order 13224 for the purpose of identifying suspected terrorists or on the most
current list published by the U.S. Treasury Department Office of Foreign Assets
Control at its official website, http://www.treas.gov/ofac/tllsdn.pdf or any
replacement website or other replacement official publication of such list.

     26.02 If either party institutes a suit against the other for violation of
or to enforce any covenant, term or condition of this Lease, the prevailing
party shall be entitled to reimbursement of all of its costs and expenses,
including, without limitation, reasonable attorneys' fees. Landlord and Tenant
hereby waive any right to trial by jury in any proceeding based upon a breach of
this Lease. No failure by either party to declare a default immediately upon its
occurrence, nor any delay by either party in taking action for a default, nor
Landlord's acceptance of Rent with knowledge of a default by Tenant, shall
constitute a waiver of the default, nor shall it constitute an estoppel.

     26.03 Whenever a period of time is prescribed for the taking of an action
by Landlord or Tenant (other than the payment of the Security Deposit or Rent),
the period of time for the performance of such action shall be extended by the
number of days that the performance is actually delayed due to strikes, acts of
God, shortages of labor or materials, war, terrorist acts, civil disturbances
and other causes beyond the reasonable control of the performing party ("FORCE
MAJEURE").

     26.04 Landlord shall have the right to transfer and assign, in whole or in
part, all of its rights and obligations under this Lease and in the Building and
Property. Upon transfer Landlord shall be released from any further obligations
hereunder and Tenant agrees to look solely to the successor in interest of
Landlord for the performance of such obligations, provided that, any successor
pursuant to a voluntary, third party transfer (but not as part of an involuntary
transfer resulting from a foreclosure or deed in lieu thereof) shall have
assumed Landlord's obligations under this Lease.

     26.05 Landlord has delivered a copy of this Lease to Tenant for Tenant's
review only and the delivery of it does not constitute an offer to Tenant or an
option. Tenant represents that it has dealt directly with and only with the
Broker as a broker in connection with this Lease. Tenant shall indemnify and
hold Landlord and the Landlord Related Parties harmless from all claims of any
other brokers claiming to have represented Tenant in connection with this Lease.
Landlord shall indemnify and hold Tenant and the Tenant Related Parties harmless
from all claims of any brokers claiming to have represented Landlord in
connection with this Lease. Equity Office Properties Management Corp. ("EOPMC")
is an affiliate of Landlord and represents only the Landlord in this
transaction. Any assistance rendered by any agent or employee of EOPMC in
connection with this Lease or any subsequent amendment or modification hereto
has been or will be made as an accommodation to Tenant solely in furtherance of
consummating the transaction on behalf of Landlord, and not as agent for Tenant.

     26.06 Time is of the essence with respect to Tenant's exercise of any
expansion, renewal or extension rights granted to Tenant. The expiration of the
Term, whether by lapse of time, termination or otherwise, shall not relieve
either party of any obligations which accrued prior to or which may continue to
accrue after the expiration or termination of this Lease.

     26.07 Tenant may peacefully have, hold and enjoy the Premises, subject to
the terms of this Lease, provided Tenant pays the Rent and fully performs all of
its covenants and agreements. This covenant shall be binding upon Landlord and
its successors only during its or their respective periods of ownership of the
Building.

     26.08 This Lease does not grant any rights to light or air over or about
the Building. Landlord excepts and reserves exclusively to itself any and all
rights not specifically granted to Tenant under this Lease. This Lease
constitutes the entire agreement between the parties and supersedes all prior
agreements and understandings related to the Premises, including all lease
proposals, letters of intent and other documents. Neither party is relying upon
any warranty, statement or representation not contained in this Lease. This
Lease may be modified only by a written agreement signed by an authorized
representative of Landlord and Tenant.

     Landlord and Tenant have executed this Lease as of the day and year first
above written.
