memorandum stipulating the actual Commencement Date. If for any reason other
than Tenant's failure to fulfill its obligations hereunder, Landlord cannot
deliver possession of the Premises to Tenant by the Construction Completion
Date, Landlord shall not be subject to any liability therefor, nor shall such
failure affect the validity of this Lease or the obligations of Tenant hereunder
or extend the Termination Date, but in such case Tenant shall not be obligated
to pay Rent until possession of the Premises is tendered to Tenant. If Tenant's
tenant improvements are not completed by the Construction Completion Date due to

comply with the terms of Exhibit C, the Lease shall be deemed to have commenced
upon the Construction Completion Date. If Tenant occupies the Premises prior to

later or earlier date than the date provided in Section 1(s) hereof, Landlord
shall confirm the same to Tenant in writing. The Lease shall expire upon the

(a) Standard Services. Landlord shall maintain the Premises and
the public and common areas of the Building (including the roof, exterior
portions of the building, parking and landscaping) in reasonably good order and
condition, except for damage occasioned by the negligent or willful act or
omission of Tenant or its contractors, agents, invitees, licensees or employees,
the repair of which damage shall be paid by Tenant, subject to the provisions of
Section 16(c). Landlord shall furnish the Premises with electricity for normal
office use, water, elevator service and reasonable 5 day per week janitorial
services during the term of the Lease. Electricity use beyond normal office use
and any separate metering required thereby shall be paid for by Tenant. The
Basic Rent stated in Section 1(k) hereof does not include the costs of any
janitorial or other service provided or caused to be provided by Landlord to
Tenant which are in addition to the services ordinarily provided Building
tenants.

Landlord shall furnish the Premises with heat and air conditioning
during the following hours; Monday to Friday 7:00 a.m. to 6:00 p.m., Saturday
8:00 a.m. - 5:00 p.m.

6
12

and Sunday 9:00 a.m. to 1:00 p,m. Tenant may request provision of these
services for other hours by giving Landlord at least 48 hours prior written
notice and by paying all additional costs incurred by Landlord for such services
with the next due installment of Rent at Landlord's then current overtime rate,
which is currently $30 per hour. During other than normal business hours (as
designated by Landlord), Landlord may restrict access to the Building in
accordance with the building's security system, provided that Tenant shall have
at all times during the term of this Lease (24 hours of all days) reasonable
access to the Premises.

(b) Interruption of Services. Landlord shall not be liable for
any loss, injury or damage to person or property caused by or resulting from any
variation, interruption, or failure of such services due to any cause
whatsoever, or from failure to make any repairs or perform any maintenance, and
rent shall not ▇▇▇▇▇ as a result thereof. No temporary interruption or failure
of such services incident to the making of repairs, alterations or improvements,
or due to accident, strike or conditions or events beyond Landlord's reasonable
control shall be deemed an eviction of Tenant or relieve Tenant from any of
Tenant's obligations hereunder.

(c) Additional Services. Before installing lights and equipment
in the Premises which in the aggregate exceed normal levels of usage (including
without limitations, computer and data processing equipment), Tenant shall
obtain the written permission of Landlord. Landlord may refuse to grant such
permission unless Tenant shall agree to pay the costs of Landlord for
installation of supplementary air conditioning capacity or electrical systems as
necessitated by such equipment or lights. Notwithstanding the above, Landlord
may not refuse to grant permission for equipment which, in the aggregate, does
not require electrical power in excess of five (5) ▇▇▇▇▇ per rentable SF.

In addition, Tenant shall in advance, on the first day of each
month during the Lease term, pay Landlord the reasonable amount estimated by
Landlord as the cost of furnishing electricity for the operation of such
equipment or lights and the reasonable amount estimated by Landlord as the cost
of operation and maintenance of supplementary air conditioning units
necessitated by Tenant's use of such equipment or lights. The Rent stated in
Section 1(k) hereof does not include any amount to cover the cost of furnishing
electricity or such additional air conditioning for such purposes and such costs
will be paid by Tenant as Additional Rent. Landlord shall be entitled to install
and operate at Tenant's cost a monitoring/metering system in the Premises to
measure the added demands on electrical, heating, ventilation and air
conditioning systems resulting from such equipment and lights and from Tenant's
after-hours heating, ventilation and air conditioning service requirements.
Tenant shall comply with Landlord's instructions for the use of drapes and
thermostats in the Building.

7. SECURITY DEPOSIT. As security for the full and faithful performance
of every covenant and condition of this Lease to be performed by Tenant, Tenant
has paid to Landlord the Security Deposit as specified in Section 1(m) hereof.
If Tenant defaults in any respect under this Lease, Landlord may apply all or
any part of the Security Deposit to the payment of any sum in default or any
other sum which Landlord may be required or may in its reasonably discretion
deems necessary to spend or incur by reason of Tenant's default. In such event,
Tenant shall, within five (5) days of written demand therefor by Landlord,

7
13

deposit with Landlord the amount so applied. If Tenant shall have fully complied
with all of the covenants and conditions of this Lease, the amount of the
Security Deposit to the extent not applied by Landlord under this Section 7
shall be repaid to Tenant (or, at Landlord's option, to the last assignee of
Tenant's interest hereunder) within thirty (30) days after the expiration or
sooner termination of this Lease. In the event of Tenant's default under this
Lease, Landlord's right to retain the Security Deposit shall be deemed to be in
addition to any and all other rights and remedies at law or in equity available
to Landlord. Landlord shall not be required to keep any Security Deposit
separate from its general funds and Tenant shall not be entitled to any interest
thereon.

8. USES.

(a) Uses. The Premises are to be used only for general office
purposes ("Permitted Uses") and for no other business or purpose without the
prior written consent of Landlord, which consent may be withheld if Landlord, in
its sole discretion, determines that any proposed use is inconsistent with or
detrimental to the maintenance and operation of the Building as a first-class
office building or is inconsistent with any restriction on use of the Premises,
the Building, the Project or the Land contained in any lease, mortgage or other
agreement or instrument by which the Landlord is bound or to which any of such
property is subject. Tenant shall not commit any act that will increase the then
existing rate of insurance on the Building or the Project and will immediately
pay any such increase. Tenant shall promptly pay upon demand the amount of any
increase in insurance rates caused by any act or acts of Tenant. Tenant shall
not commit or allow to be committed any waste upon the Premises, or any public
or private nuisance or other act which disturbs the quiet enjoyment of any other
tenant in the Building or which is unlawful. Tenant shall not, without the
written consent of Landlord, use any apparatus, machinery or device in or about
the Premises which will cause any substantial noise, vibration or fumes. If any
of Tenant's office machines or equipment should disturb the quiet enjoyment of
any other tenant in the Building, then Tenant shall provide adequate insulation
or take other action as may be necessary to eliminate the disturbance.

(b) Compliance With Law. Tenant shall, at Tenant's expense,
comply promptly with all applicable statutes, ordinances, rules, regulations,
orders and requirements, including without limitation laws and regulations
prohibiting discrimination on the basis of race, gender, religion, national
origin, age or disability, in effect during the term hereof regulating the use,
occupancy or improvement of the Premises by Tenant, Landlord or otherwise and
Tenant shall be fully responsible for the cost of complying therewith.

(c) Compliance With Rules and Regulations. Tenant shall observe
and comply with all reasonable rules and regulations put into effect by
Landlord. Landlord shall not be responsible to Tenant for the non-compliance
with the rules and regulations of any other tenant or occupant of the Project.

9. IMPROVEMENTS. Upon expiration or sooner termination of this Lease,
all improvements and additions to the Premises, except Tenant's trade fixtures,
shall be deemed the property of Landlord.

8
14
10. TENANT IMPROVEMENTS; ACCEPTANCE OF PREMISES. The Premises shall be
completed in accordance with the plans and specifications attached hereto as
Exhibit C. All necessary construction shall be commenced by Landlord following
Landlord's execution of this Lease and Tenant's delivery of the first month's
Basic Rent, the guarantees and the Security Deposit. Landlord will exert
commercially reasonable efforts to have improvements substantially completed by
the date set forth in Section 1(s). Within five (5) days ("Inspection Period")
after Landlord informs Tenant of such completion, Tenant shall make such
inspection of the Premises as Tenant deems appropriate. Except as otherwise
specified by Tenant in writing to Landlord within the Inspection Period, Tenant
shall be deemed to have accepted the Premises in their then condition. If, as a
result of such inspection, Tenant discovers minor deviations or variations from
the plans and specifications for Tenant's improvements of a nature commonly
found on a "punch list" (as the term is used in the construction industry),
Tenant shall, during the Inspection Period, notify Landlord of such deviations.
Landlord shall promptly repair all punch list items. The existence of such punch
list items shall not postpone the Commencement Date of this Lease or the
obligation of Tenant to pay Rent. Tenant acknowledges that neither Landlord nor
Landlord's agent has made any representation or warranty as to the suitability
of the Premises for the conduct of Tenant's business, and Tenant hereby waives
any rights, claims or actions against Landlord under any express or implied
warranties of suitability.

11. CARE OF PREMISES. Tenant shall, at Tenant's sole cost and expense,
keep the Premises and every part thereof in good condition and repair, damage
thereto from causes beyond the reasonable control of Tenant and ordinary wear
and tear and damage by fire and other casualty not intentionally caused by
Tenant excepted. Tenant shall be responsible for the cleaning of any common
areas of the Building and the Project if such cleaning is necessary due to
Tenant's use of such common areas in a manner other than the normal, reasonable
use of such areas. All damages or injury done to the Premises, Building or
Project by Tenant or by any persons who may be in or upon the Premises, Building
or Project with the express or implied consent of Tenant, including but not
limited to the cracking or breaking of any glass of windows and doors, shall be
paid for by Tenant and Tenant shall pay for all damage to the Project caused by
acts or omissions of Tenant or Tenant's officers, contractors, agents, invitees,
licensees, or employees subject to the provisions of section 16(c). If Tenant
fails to perform Tenant's obligations under this Section 11, Landlord may at
Landlord's option enter upon the Premises after ten (10) days' prior notice to
Tenant and put the affected portion of the Project in good order, condition and
repair and the cost thereof together with interest thereon at the rate of 15%
per annum shall be due and payable as Additional Rent to Landlord together with
Tenant's next installment of Basic Rent. All normal repairs shall be those
reasonably determined by Landlord as necessary to maintain the Project as a
first-class office building complex.

12. ALTERATIONS AND ADDITIONS.

(a) Tenant shall not make any alterations, improvements,
additions, or utility installations in or about the Premises or make changes to
locks on doors, or add, disturb or in any way change any floor covering, wall
covering, fixtures, plumbing or wiring (collectively, "Alterations") without
first obtaining the written consent of Landlord and, where appropriate, in
accordance with plans and specifications approved by Landlord. Any such

9
15
Alterations shall not adversely affect either the strength or exterior
appearance, or the mechanical, electrical, or plumbing services of the Building
and the Project. Any alterations required to be made to the Premises by any
applicable building, health, safety, fire, nondiscrimination, or similar law or
regulation ("law"), but only to the extent such alterations are not also
required to be made generally throughout the building, shall be made at Tenant's
sole expense and shall be subject to the prior written consent of Landlord.
Tenant shall reimburse Landlord for any sums expended for examination and
approval of architectural or mechanical plans and specifications of the
Alterations. Tenant shall also pay Landlord a sum equal to the direct costs
incurred during any inspection or supervision of the Alterations. Landlord may
require a lien and completion bond for such construction, or require the
improvements (except for any cabling installed by the Tenant) be removed at the
expiration of the Term. Tenant acknowledges and agrees that a material condition
to the granting of approval of Landlord to any alterations and/or improvements
and/or repairs required under this Lease or desired by Tenant is that the
contractors who perform such work shall carry a Comprehensive Liability Policy
covering both bodily injury, in the amount of $100,000 per person and $300,000
aggregate, and property damages, in the amount of $300,000, at Tenant's expense.
Landlord may require proof of such insurance coverage from each contractor at
the time of submission of Tenant's request for Landlord's consent to commence
work. Landlord's approval of the plans, specifications and working drawings for
Tenant's alterations shall create no responsibility or liability on the part of
Landlord for their completeness, design sufficiency, or compliance with all
laws, rules and regulations of governmental agencies or authorities. Tenant
shall indemnify and hold Landlord harmless from any liability, claim or suit,
including attorneys' fees, arising from any injury, damage, cost or loss
sustained by persons or property as a result of any defect in design, material
or workmanship.

(b) Tenant shall pay, when due, all claims for labor or
materials furnished to or for Tenant at or for use in the Premises, which claims
are or may be secured by any mechanics' or materialmen's liens against the
Premises or any interest therein. Within ten (10) days after notice thereof,
Tenant shall remove or cause to be removed all liens filed against the Project
or any portion thereof in connection with any Alterations or other work
performed by or at the request of Tenant.

(d) Unless Landlord requires their removal, all Alterations
(other than trade fixtures and movable equipment) which may be made on the
Premises shall become the property of Landlord and remain upon and be
surrendered with the Premises at the expiration of the term.

13. ACCESS. Tenant shall permit Landlord and its agents to enter the
Premises at all reasonable times for the purpose of inspecting, cleaning,
repairing, altering or improving the Premises or the Building. Nothing contained
in this Section 13 shall be deemed to impose any obligation upon Landlord not
expressly stated elsewhere in this Lease. Landlord may temporarily close any
portion of the Building or Project without liability to Tenant by reason of such
closure, and such closure shall not constitute an eviction of Tenant or release
Tenant from any Rent or other obligations hereunder,

10
16

provided that the Landlord does not preclude Tenant's access to the premises and
such closure does not materially interfere with Tenant's use and occupancy of
the premises. Landlord shall have the right to enter the Premises for the
purpose of showing the Premises to prospective purchasers or mortgagees at all
reasonable times. Landlord shall have the right to enter the Premises for the
purpose of showing the Premises to prospective tenants within the period of one
hundred eighty (180) days prior to the expiration or sooner termination of the
Lease term.

14. DAMAGE OR DESTRUCTION.

(a) Damage and Repair. If the Building is damaged by fire or any
other cause to such extent that the cost of restoration, as reasonably estimated
by Landlord, will equal or exceed thirty percent (30%) of the replacement value
of the Building, or if insurance proceeds sufficient for restoration are for any
reason unavailable, then Landlord may, no later than the sixtieth day following
the damage, give Tenant a notice of Landlord's election to terminate this Lease.
In the event of such election this Lease shall be deemed to terminate on the
third day after the giving of such notice, Tenant shall surrender possession of
the Premises within a reasonable time thereafter, the Rent and Additional Rent
shall be apportioned as of the date of Tenant's surrender and any Rent paid for
any period beyond such date shall be repaid to Tenant. If the cost of
restoration as estimated by Landlord shall amount to less than thirty percent
(30%) of said replacement value of the Building and insurance proceeds
sufficient for restoration are available, or if Landlord does not elect to
terminate this lease, Landlord shall restore the Building and the Premises (to
the extent of the improvement of the Premises originally provided by Landlord
hereunder) with reasonable promptness, subject to delays beyond Landlord's
control and delays in the making of insurance adjustments by Landlord. To the
extent that the Premises are rendered untenantable, the Rent shall
proportionately ▇▇▇▇▇, except in the event such damage resulted from the willful
or intentional act or omission of Tenant, in which event Rent shall ▇▇▇▇▇ only
to the extent Landlord receives proceeds from any rental income insurance policy
to compensate Landlord for loss of Rent hereunder.

(b) Destruction During Last Year of Term. In case the Building
shall be substantially destroyed by fire or other cause at any time during the
last Lease Year of this Lease, Landlord may terminate this Lease upon written
notice to Tenant if given within sixty (60) days of the date of such
destruction.

(c) Business Interruption. No damages, compensation or claim
shall be payable by Landlord for inconvenience, loss of business or annoyance
arising from any repair or restoration of any portion of the Premises, the
Building or the Project. Landlord shall use its best efforts to effect such
repairs promptly.

(d) Tenant Improvements. Landlord will not carry insurance of
any kind on any improvements paid for by Tenant as provided in Exhibit C or on
Tenant's furniture, furnishings, fixtures, equipment or appurtenances of Tenant
under this Lease and Landlord shall not be obligated to repair any damage
thereto or replace the same.

15. CONDEMNATION.

11
17

(a) Taking. If all of the Premises or such portions of the
Building or Project as may be required for the reasonable use of the Premises
are taken by eminent domain, this Lease shall automatically terminate as of the
date title vests in the condemning authority. In the event of a taking of a
material part, but less than all, of the Building or Project, where Landlord
shall determine that the remaining portions of the Building or Project cannot be
economically and effectively used by it (whether on account of physical,
economic, aesthetic or other reasons) or where Landlord determines the Building
should be restored in such a way as to materially alter the Premises, Landlord
shall forward a written notice to Tenant of such determination not more than
sixty (60) days after the date of taking. The term of this Lease shall expire
upon such date as Landlord shall specify in such notice but not earlier than
sixty (60) days after the date of such notice. In case of taking of a part of
the Premises, or a portion of the Building or Project not required for the
reasonable use of the Premises, then this Lease shall continue in full force and
effect and the Rent shall be equitably reduced based on the proportion by which
the floor area of the Premises is reduced; however, if the floor area of the
premises is reduced by more than five percent (5%), Tenant may terminate this
Lease upon thirty (30) days notice to Landlord.

(b) Awards and Damages. Landlord reserves all rights to damages
to the Premises for any partial, constructive, or entire taking by eminent
domain, and Tenant hereby assigns to Landlord any right Tenant may have to such
damages or award, and Tenant shall make no claim against Landlord or the
condemning authority for damages for termination of the leasehold interest or
interference with Tenant's business. Tenant shall have the right, however, to
claim and recover from the condemning authority compensation for any loss to
which Tenant may be put for Tenant's moving expenses, business interruption or
taking of Tenant's personal property (not including Tenant's leasehold interest)
provided that such damages may be claimed only if they are awarded separately in
the eminent domain proceedings and not out of or as part of the damages
recoverable by Landlord.

16. INDEMNIFICATION.

(a) Indemnity. Subject to provisions of section 16.c, Tenant
shall indemnify, defend and hold Landlord harmless from and against all loss,
cost and expense, including attorneys fees, arising from any act, omission, or
negligence of Tenant or its officers, contractors, licensees, agents, servants,
employees, guests, invitees, or visitors in or about the Premises or Project, or
arising from any injury or damage to any person or property, occurring in or
about the Premises or Project as a result of any act, omission or negligence of
Tenant, or its officers, contractors, licensees, agents, employees, guests, or
visitors or arising from any breach or default under this Lease by Tenant. The
foregoing provisions shall not be construed to make Tenant responsible for loss,
damage, liability or expense resulting from injuries to third parties caused
solely by the gross negligence of Landlord, or its officers, contractors,
licensees, agents, employees, invitees or other tenant of the Project.

(b) Exemption of Landlord From Liability. As a material part of
the consideration to Landlord, Tenant hereby agrees that, notwithstanding
anything to the contrary in Section 16(a) above, Landlord shall in no event be
liable for injury to Tenant's business or assets or any loss of income therefrom
or for damage to Tenant's employees,

12
18

invitees, customers, or any other person in or about the Premises, whether such
damage, loss or injury results from conditions arising upon the Premises or upon
other portions of the Project of which Premises are a part (including, without
limitation, damage caused by the Project or any portion thereof or a
appurtenance thereto being out of repair, or the bursting, leakage of any water,
gas, sewer or steam pipe), or from other sources or places, and regardless of
whether the cause of such damage, loss or injury or the means of repairing the
same is inaccessible to Tenant. Tenant further agrees that notwithstanding
anything to the contrary in Section 16(a) above, Landlord shall in no event be
liable for any injury or damage to any person or property of Tenant, Tenant's
employees, invitees, customers, agents or contractors caused by theft or arising
from any act, omission or neglect of any tenant or occupant of the Project or
any other third person.

(c) Waiver of Subrogation. Each party agrees to use commercially
reasonable efforts to cause its insurance carriers to consent to a waiver of
rights of subrogation against the other party. If such waiver shall be
obtainable only at a premium over that chargeable without such a waiver, the
party seeking such policy shall notify the other and the party in whose favor
the waiver is desired shall pay the additional premium. Each party shall look
first to any insurance in its favor before making claim against the other party.
Whether the loss or damage is due to the negligence of either Landlord or
Tenant, their agents or employees, or any other cause, Landlord and Tenant do
each hereby release and relieve the other, their agents or employees, from
responsibility for, and waive their entire claim of recovery for (i) any loss or
damage to the real or personal property of either located anywhere in the
Project, including the Project itself, arising out of or incident to the
occurrence of any of the perils which are covered by their respective property
and related insurance policies, and (ii) any loss resulting from business
interruption at the Premises or loss of rental income from the Project, arising
out of or incident to the occurrence of any of the perils which may be covered
by any business interruption insurance policy or by any loss of rental income
insurance policy held by Landlord or Tenant, to the extent to which it is
covered, or is required under the provisions of this Lease to be covered by a
policy or policies containing a waiver of subrogation or permission to release
liability.

17. HAZARDOUS SUBSTANCES.

Tenant shall not dispose of or otherwise allow the release of any
hazardous waste or materials in, on or under the Premises, the Project or any
adjacent property, except for normal office products used and disposed of in
accordance with applicable laws. Tenant represents and warrants to Landlord that
Tenant's intended use of the Premises does not involve the use, production,
disposal or bringing on to the Premises or the Project of any hazardous waste or
materials, except for normal office products used and disposed of in accordance
with applicable laws. As used herein, the term "hazardous waste or materials"
means any material or substance that, as of the date of this Agreement, is
defined or classified under federal, state, or local laws as: (a) a "hazardous
substance" pursuant to section 101 of the Comprehensive Environmental Response,
Compensation and Liability Act, 42 U.S.C. Section 9601(4), section 311 of the
Federal Water Pollution Control Act, 33 U.S.C. Section 1321; (b) a "hazardous
waste" pursuant to section 1004 or section 3001 of the Resource Conservation and
Recovery Act, 42 U.S.C. sections 6903,6921; (c) a toxic pollutant under section
307(a)(1) of the Federal Water Pollution Control Act, 33 U.S.C.

13
19
Section 1317(a)(1); (d) a "hazardous air pollutant" under section 112 of the
Clean Air Act, 42 U.S.C. Section 7412; (e) a "hazardous Material" under the
Hazardous Materials Transportation Uniform Safety Act of 1990, 49 U.S.C. App.
Section 1802(4); (f) toxic or hazardous pursuant to regulations promulgated
under the aforementioned laws; or (g) presenting a risk to the environment under
other applicable federal, state, or local laws, ordinances, or regulations.
"Hazardous Substances" specifically include, but is not limited to, asbestos,
polychlorinated biphenyls ("PCBs"), petroleum and petroleum-based derivatives,
and urea formaldehyde. Tenant shall promptly comply with all applicable laws and
with all orders, decrees or judgments of governmental authorities or courts
having jurisdiction relating to hazardous waste or materials.

Tenant agrees to indemnify, defend and hold harmless Landlord against
any and all loss, cost and expense (including, without limitation, consultants'
fees, attorneys' fees and disbursements) which may be imposed on, incurred or
paid by, or asserted against Landlord or the Premises or the Project by reason
of, or in connection with (i) any misrepresentation, breach of warranty or other
default by Tenant under this Lease, or (ii) the acts or omissions by Tenant
under this Lease, or (iii) the acts or omissions of Tenant, or any sublessee or
other person for whom Tenant would otherwise be liable, resulting in the release
of any hazardous waste or materials.

18. INSURANCE.

(a) Required Policies. Tenant shall, throughout the term of this
Lease and any renewal hereof, at its own expense, keep and maintain in full
force and effect: (i) a policy of commercial liability insurance including a
contractual liability endorsement covering Tenant's obligations under Section 16
and 17, with a limit of not less than One Million Dollars ($1,000,000) combined
single limit (the limits of said insurance shall not, however, limit the
liability of Tenant hereunder); and (ii) what is commonly referred to as "all
risk" coverage insurance (but excluding earthquake and flood) on Tenant's
leasehold improvements in an amount not less than the current One Hundred
Percent (100%) replacement value thereof; and (iii) business interruption
insurance in an amount sufficient to cover costs, expenses, costs due hereunder,
damages and lost income should the Premises not be fully usable for a period of
up to 6 months. Such policy shall name Landlord as an additional insured and
shall contain a provision or endorsement providing that the insurance afforded
by such policy for the benefit of Landlord shall be primary as respects any
claims, losses or liabilities arising out of the use of the Premises or the
Building or the Common Areas by the Tenant or by tenant's operation and that any
insurance carried by Landlord shall be excess and non-contributing.

(b) Insurance Policy Requirements. Insurance policies required
hereunder shall be issued by companies which are currently rated AXII or better
in "Best's Insurance Guide." No insurance policy required under this Section 18
shall be canceled or reduced in coverage and each insurance policy shall provide
that it is not subject to cancellation or a reduction in coverage except after
thirty (30) days prior written notice to Landlord.

Tenant shall deliver to Landlord upon the Commencement Date and from
time to time thereafter, copies of policies of such insurance or certificates
evidencing the existence

14
20

and amounts of same containing loss payable clauses satisfactorily to Landlord
and naming Landlord as Additional Insured thereunder.

(c) Landlord's Insurance. Landlord agrees to acquire, maintain
and pay for, during the full term of this Lease, "all risk" property damage
insurance against such risks and hazards as are customarily insured against by
others similarly situated and operating like properties, but excluding
earthquake and flood, covering the Building, including the Premises for such
amounts and upon such terms as would a prudent owner of such property similar to
and in the general area of the Building, and shall name Tenant as an additional
insured thereon. Such insurance shall be acquired from a company authorized to
do business in the State of Washington and rated as AXII or better in "Best's
Insurance Guide." Upon request by Tenant, Landlord shall notify Tenant of the
amount and type of insurance carried by Landlord pursuant to this section.

19. ASSIGNMENT AND SUBLETTING.

(a) Tenant shall not assign, mortgage, encumber or otherwise
transfer this Lease or sublet the whole or any part of the Premises without in
each case first obtaining Landlord's prior written consent, which Landlord may
not unreasonably withhold. Without limiting the foregoing, Landlord may withhold
its consent if in Landlord's judgment occupancy by any proposed assignee,
subtenant or other transferee: (i) is not consistent with the maintenance and
operation of a first-class suburban office building due to the proposed
occupant's nature or manner of conducting business or its experience or
reputation in the community, or (ii) is likely to cause disturbance to the
normal use and occupancy of the Building or Project by other tenants, their
employees, customers, clients or other guests or visitors. Landlord may withhold
in its absolute and sole discretion, consent to any mortgage, hypothecation,
pledge or other encumbrance of any interest in this Lease by Tenant or any
subtenant, whereby this Lease or any interest therein becomes collateral for any
obligation of Tenant or any other person.

(b) In the event Tenant should desire to assign this Lease or
sublet the Premises or any part hereof, Tenant shall give Landlord written
notice at least forty five (45) days in advance of the date on which Tenant
desires to make such assignment or sublease, which notice shall specify, (i) the
name and business of the proposed assignee or sublessee, (ii) the amount and
location of the space affected, (iii) the proposed effective date and duration
of the subletting or assignment, and (iv) the proposed rental to be paid to
Tenant by such sublessee or assignee. Landlord shall then have a period of
twenty (20) days following receipt of such notice within which to notify Tenant
in writing that Landlord elects either (1) to terminate this Lease as to the
space so affected as of the date so specified by Tenant and reclaim that portion
of the Premises (in which event Landlord may enter into a lease with any such
proposed subtenant or assignee upon the rent and terms agreed to by each
subtenant or assignee or on such other terms as may be agreed upon by Landlord
and such subtenant or assignee) or, (2) to permit Tenant to assign or sublet
such space, in which event if the proposed rental rate between Tenant and
sublessee is greater than the rental rate of this Lease, then such excess rental
to be deemed additional rent owed by Tenant to Landlord under this Lease, and
the amount of such excess, including any subsequent increases due to escalation
or otherwise, to be paid by Tenant to Landlord in the same manner that Tenant
pays the rental hereunder and in addition thereto, or (3) to

15
21

withhold consent to Tenant's assignment or subleasing such space and to continue
this Lease in full force and effect as to the entire Premises.

(c) Except as provided above, no assignment, subletting or other
transfer shall relieve Tenant of any liability under this Lease. Consent to any
such assignment, subletting or transfer shall not operate as a waiver of the
necessity for consent to any subsequent assignment, subletting or transfer. In
connection with each request for an assignment or subletting, Tenant shall pay
the reasonable cost of processing such assignment or subletting, including
attorneys fees, upon demand of Landlord. Tenant shall provide Landlord with
copies of all assignments, subleases and assumption instruments. If Tenant is a
corporation or partnership, any transfer of a controlling ownership interest in
Tenant or any transfer of this Lease by merger, consolidation or liquidation,
shall be deemed an assignment under this Section 19. Any assignee or subtenant
shall assume all of Tenant's obligations under this Lease and be jointly and
severally liable with Tenant hereunder.

20. LIENS AND INSOLVENCY.

(a) Liens. Tenant shall keep its interest in this Lease and any
Property of Tenant (other than unattached personal property) and the Premises,
and the Project free from any liens arising out of any work performed or
materials ordered or obligations incurred by or on behalf of Tenant and hereby
indemnifies and holds Landlord harmless from any liability from any such lien.
In the event any lien is filed against the Premises, the Project or any portion
thereof by any person claiming by, through or under Tenant, Tenant shall, upon
request of Landlord, at Tenant's expense, immediately either cause such lien to
be released of record or furnish to Landlord a bond in form and amount and
issued by a surety satisfactory to Landlord, indemnifying Landlord, and the
Project against all liability, costs and expenses, including attorneys fees,
which Landlord may incur as a result thereof. Provided that such bond has been
furnished to Landlord, Tenant, at its sole cost and expense and after written
notice to Landlord, may contest, by appropriate proceedings conducted in good
faith and with due diligence, any lien, encumbrance or charge against the
Premises arising from work done or materials provided to and for Tenant, if, and
only if, such proceedings suspend the collection thereof against Landlord,
Tenant and the Premises and neither the Premises, nor the Project, nor any part
thereof or interest therein is or will be in any danger of being sold, forfeited
or lost.

(b) Insolvency. If Tenant becomes insolvent or voluntarily or
involuntarily bankrupt, or if a receiver, assignee or other liquidating officer
is appointed for the business of tenant, Landlord at its option may terminate
this Lease and Tenant's right of possession under this Lease and in no event
shall this Lease or any rights or privileges hereunder be an asset of Tenant in
any bankruptcy, insolvency or reorganization proceeding.

21. DEFAULT.

(a) Default By Tenant. The occurrence of any one or more of the
following events shall constitute a material default and breach of this Lease by
Tenant: (i) the abandonment of the Premises by Tenant or the vacating of the
Premises for more than thirty (30) consecutive days; (ii) the failure by Tenant
to make any payment of Rent or any

16
22
other payment required to be made by Tenant hereunder, within five (5) days of
date due; (iii) the failure by Tenant to observe or perform any of the other
covenants, conditions or provisions of the Lease, where such failure shall
continue for a period of twenty (20) days; provided, however, if more than
twenty (20) days are reasonably required for its cure then Tenant shall not be
deemed to be in default if Tenant commences such cure within said 20-day period
and thereafter diligently prosecutes such cure to completion; (iv) the making by
Tenant of any general assignment or general arrangement for the benefit of
creditors; (v) the filing by or against Tenant of a petition to have Tenant
adjudged bankrupt or a petition for reorganization or arrangement under any law
relating to bankruptcy (unless, in the case of a petition filed against Tenant,
the same is dismissed within sixty (60) days); (vi) 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 the Lease, where possession is not
restored to Tenant within thirty (30) days; (vii) the attachment, execution or
other judicial seizure of substantially all of Tenant's assets located at the
Premises or of Tenant's interest in this Lease, where such seizure is not
discharged within thirty (30) days. The above notice periods may, at the
election of Landlord, run concurrently with any statutorily required notice
periods.

(b) Remedies Cumulative; Injunction. All rights and remedies of
Landlord herein enumerated shall be cumulative, and none shall exclude any other
right or remedy allowed by law or in equity. In addition to the other remedies
in this Lease provided, Landlord shall be entitled to restrain by injunction the
violation or attempted violation of any of the covenants, agreements or
conditions of this Lease.

(c) Landlord's Remedies Upon Tenant Default. Upon an uncured
default of this Lease by Tenant, Landlord, besides other rights or remedies it
may have, at its option, may enter the Premises or any part thereof, either with
or without process of law, and expel, remove or put out Tenant or any other
persons who may be thereon, together with all personal property found therein.
No such reentry shall be construed as an election on Landlord's part to
terminate this Lease unless a written notice of such intention is given to
Tenant. Landlord may terminate this Lease, or it may from time to time, without
terminating this Lease and as agent of Tenant, relet the Premises or any part
thereof for such term or terms (which may be for a term less than or extending
beyond the term hereof) and at such rental or rentals and upon such other terms
and conditions as Landlord in its sole discretion may deem advisable, with the
right to repair, renovate, remodel, redecorate, alter and change the Premises,
Tenant remaining liable for any deficiency computed as hereinafter set forth. In
the case of any default, re-entry and/or dispossession, by summary proceedings
or otherwise, all Rent and Additional Rent shall become due thereupon and be
paid up to the time of such re-entry or dispossession, together with such
expenses as Landlord may reasonably incur for attorneys fees, advertising
expenses, brokerage fees and/or putting the Premises in good order or preparing
the same for re-rental, together with interest thereon as provided in Section
30(q) hereof, accruing from the date of any such expenditure by Landlord.

At the option of Landlord, rents received by Landlord from such
reletting shall be applied first to the payment of any indebtedness from Tenant
to Landlord other than Rent and Additional Rent due hereunder; second, to the
payment of any costs and expenses of

17
23

such reletting and including, but not limited to, attorneys fees, advertising
fees and brokerage fees, and to the payment of any repairs, renovations,
remodeling, redecoration, alterations, and changes in the Premises; third, to
the payment of Rent and Additional Rent due and to become due hereunder, and if
after so applying said Rents there is any deficiency in the Rent or Additional
Rent to be paid by Tenant under this Lease, Tenant shall pay any deficiency to
Landlord monthly on the dates specified herein and any payment made or suits
brought to collect the amount of the deficiency for any month shall not
prejudice in any way the right of Landlord to collect the deficiency for any
subsequent month. The failure or refusal of Landlord to relet the Premises or
any part or parts thereof shall not release or affect Tenant's liability
hereunder, nor shall Landlord be liable for failure to relet, or in the event of
reletting, for failure to collect the Rent thereof, and in no event shall Tenant
be entitled to receive any excess of net Rents collected over sums payable by
Tenant to Landlord hereunder, however, Landlord shall have the obligation to
exert reasonable efforts to mitigate damages, provided that Landlord shall not
be required to relet the Premises prior to leasing any other space owned by the
Landlord, or its affiliates, within a one mile radius. No such re-entry or
taking possession of the Premises shall be construed as an election on
Landlord's part to terminate this Lease unless a written notice of such
intention be given to Tenant. Notwithstanding any such reletting without
termination, Landlord may at any time thereafter elect to terminate this Lease
for such previous breach and default. Should Landlord at any time terminate this
Lease by reason of any default, in addition to any other remedy it may have, it
may recover from Tenant the present value, using a ten percent (10%) discount
rate, of the amount of Rent and Additional Rent reserved in this Lease for the
balance of the Term, as it may have been extended, less the amount that Tenant
proves could be collected for the remainder of the Term, plus all court costs
and attorneys fees incurred by Landlord in the collection of the same.

Tenant acknowledges that certain benefits or concessions provided by
Landlord are conditioned upon Tenant's timely, full and faithful performance of
each and every obligation, covenant, representation and warranty of this Lease
throughout the entire term of this Lease, even though such benefits or
concessions may be realized by Tenant over less than the entire term of this
Lease. Accordingly, notwithstanding anything to the contrary contained herein,
in the event Landlord brings an action against Tenant for default under this
Lease which results in a termination of this Lease and eviction of Tenant,
Landlord shall become immediately entitled to receive from Tenant as Additional
Rent the amount of all such benefits and concessions allocable to the balance of
the Lease term on a pro rata basis, i.e. an amount equal to the product of (x)
the sum of (a) any amounts theretofore or thereafter paid by Landlord to Tenant
or to any third party, or any amounts credited to Tenant or to any third party,
for or on account of (i) any moving, tenant improvement, decorating or other
allowance or credit granted to Tenant but only to the extent such tenant
improvements are demolished for the next occupant of the premises, (ii) any real
estate commission paid on account of this Lease, and (iii) any expenses or costs
related to assumption by Landlord of any other lease, plus (b) an amount equal
to the difference between the rent as specified in Section 4 above and rent for
any period for which this Lease provides any lesser amount including zero or
nominal rent, including for any period of early occupancy of the Premises prior
to the commencement of the term of this Lease, plus (c) the amount spent by
Landlord for any tenant improvements to the Premises but only to the extent such
tenant improvements are demolished for the next

18
24

occupant of the premises; multiplied by (y) a fraction, the numerator of which
is the number of days of the term of this Lease remaining between the date of
default and the expiration of the term of this Lease, and the denominator of
which is the total number of days of the term of this Lease. By way of example,
if Tenant receives a moving allowance of $1,000, the Lease term is 3 years
(1,095 days) and a default occurs at the end of the first year such that there
were 2 years (730 days) remaining, the Tenant shall pay as additional rent the
sum of $666.67, which is computed as follows: ($1,000 x 730) / 1,095 = $666.67.

(d) Waiver of Redemption Rights. Tenant, for itself, and on
behalf of any and all persons claiming through or under it, including creditors

or the Project or any portion thereof containing the Premises, created by or at
the instance of Landlord, and to any and all advances to be made thereunder and

any Landlord's Mortgage or any person or persons purchasing or otherwise

to continue this Lease in full force and effect; and in such event, Tenant shall
attorn to such person or persons. Tenant shall properly execute, acknowledge and
deliver documents which the holder of any Landlord's Mortgage may require to
effectuate the provisions of this Section 22 within five (5) days after
Landlord's request. Not withstanding the above, Landlord shall use commercially

mortgage, that such holder will not disturb Tenant's rights pursuant to this

Lease.

Basic Rent and the amount of Additional Rent currently being paid towards
increases in Operating Costs, and the date to which such Rent has been paid; and

assigned or amended in any way (or specifying the date and terms of agreement so
affecting this Lease); (ii) whether this Lease represents the entire agreement
between the parties as to this leasing; that all obligations under this Lease to
be performed by the Landlord have been satisfied or specifying those that have
not been satisfied; (iii) whether on this date there are no existing claims,
defenses or offsets which the Tenant has against the enforcement of this Lease
by the Landlord; (iv) whether no Rent has been paid more than one month in

It is intended that any such statement delivered pursuant to this Section may be
relied upon by a prospective purchaser of Landlord's interest or holder of any
mortgage upon Landlord's interest in the Building or the Project.

(b) Failure to Deliver Estoppel. If Tenant shall fail to respond
within ten (10) days of receipt by Tenant of a written request by Landlord as
herein provided, Tenant shall be deemed to have given such certificate as above
provided without modification and shall be deemed to have admitted the accuracy
of any information supplied by Landlord to a prospective purchaser or mortgagee
and to have certified that this Lease is in full force and effect, that there
are no uncured defaults in Landlord's performance, that the security deposit is
as stated in the Lease, and that not more than one month's Rent has been paid in

removal; any property not so removed shall be deemed abandoned and may be sold
or otherwise disposed of as Landlord deems advisable.

25. NON-WAIVER. Waiver by Landlord of any term, covenant or condition
herein contained or any breach thereof shall not be deemed to be a waiver of
such term, covenant, or condition or of any subsequent breach of the same or any
other term, covenant, or condition herein contained. The subsequent acceptance
of Rent or Additional 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 or
Additional Rent so accepted, regardless of Landlord's knowledge of such
preceding breach at the time of acceptance of such Rent or Additional Rent.

transferee.

required to be paid by it hereunder or shall fail to perform any other act on
its part to be performed hereunder, and such failure shall continue for ten (10)

so to do, and without waiving or releasing Tenant from any obligations of
Tenant, make such payment or perform any such other act on Tenant's part to be

at the expiration or sooner termination of this Lease and Tenant shall repair
any damage to the Premises, the Building or the Project caused thereby.

reasonable rules and regulations as set forth in Exhibit D, which shall be

EXHIBIT E

RESTATED
GUARANTY OF LEASE

▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇ ("Guarantor"), hereby agrees with Seattle Office Associates
LLC ("Landlord"), as follows:

1. Consideration: Guarantor has agreed to make and deliver this Guaranty to
Landlord in order to induce Landlord to enter into a new lease dated
March , 1997 with bsquare consulting, inc. (Tenant) with respect to
Suite 100 of the Delphi Building in Bellevue, WA (the "Suite 100
Lease"), and also to induce Landlord to enter into a new lease dated
March , 1997 with Tenant with respect to Suite 310 of the Delphi
Building (the "Suite 310 Lease"). Landlord and Tenant are also parties
to a lease dated November 15, 1996, as amended, with respect to Suite
200 of the Delphi Building (the "Suite 200 Lease"). The Suite 100 Lease,
the Suite 200 Lease and the Suite 310 Lease are collectively referred
to as the "Leases", and are the Leases under which the obligations
hereby guaranteed have been created. Guarantor hereby acknowledges that
it has and will derive a direct financial benefit from Landlord's
entering into the Leases. This Guaranty replaces and supersedes in its
entirety the Guaranty of Lease from Guarantor to Landlord for the Suite
200 Lease dated November 15, 1996.

2. Guarantee: Guarantor hereby guarantees the Leases, as originally
executed and as thereafter modified or amended, as follows: Guarantor
hereby guarantees and undertakes with Landlord that in the event that
the Tenant shall default in the payments of any sums due and owing to
Landlord from Tenant on account of any of the Leases or in the event
that the Tenant shall default in the full and faithful performance of
Tenant's obligations, undertakings and covenants contained in the
Leases, then Guarantor shall pay to Landlord, within ten days of demand,
any and all sums so due to Landlord (not to exceed the limitation set
forth below) and any damages incurred by Landlord on account thereof.
This guaranty is absolute and unconditional. Guarantor's total
obligation under this guarantee is limited to $299,000 (the "Limit
Amount").

3. Reductions in Limit Amount: Guarantor shall have the right to reduce the
Limit Amount by $2.32 for each $1.00 in cash deposited by Guarantor with
Landlord, provided that the maximum amount Guarantor may reduce the
Limit Amount by cash deposit may not exceed $174,000 ($75,000 in cash).
Any cash deposited by Guarantor with Landlord to reduce the Limit Amount
shall accrue interest at the rate of 5% per annum, which interest shall
be credited to the cash deposit on a monthly basis. Any cash deposited
with Landlord to reduce the Limit Amount shall be held by Landlord with
landlord's other funds, and shall be available to Landlord on the same
terms and conditions as the security deposits under the Leases. Any
remaining portion of the cash deposit (and any accrued interest thereon)
shall be returned to Guarantor only after all of the Leases have expired
and all of the obligations of Tenant thereunder have been satisfied in
full.

Any reduction in the Limit Amount arising from a cash deposit with
Landlord shall only be effective as to obligations arising under this
Guaranty accruing after the date of deposit. Obligations which have
accrued under the Guaranty prior to or as of the date of a cash deposit
with Landlord shall still be subject to the full Limit Amount. Thus,
following a default by Tenant under a Lease, Guarantor may not make a
cash deposit with Landlord to reduce the Limit Amount applicable to such
default.

The Limit Amount shall also be reduced $3,472.22 per month for each
month which the Tenant is not in default under any of the Leases,
provided that in no event shall the Limit Amount be reduced by more than
$125,000 by operation of this provision. This monthly reduction is to
begin December 13, 1996.

4. Term: Guarantor's obligations and undertakings herein contained shall
remain in full force and effect and shall survive termination of the
Leases.

5. Rights of Landlord: Without diminishing, releasing or discharging
Guarantor's obligations hereunder, Landlord shall have the right to
exercise the following powers and rights in Landlord's sole discretion:
Landlord may change, alter, cancel, renew, extend, decrease or increase
the obligations of Tenant to Landlord (increases in the

Page 1
41

obligation of the Tenant to Landlord will not increase the Limit Amount
under this guaranty). Landlord may add other guarantors or procure
additional guarantees, release other guarantors or guarantees and apply
monies or properties received from Tenant upon debts regardless of
whether the same may be guaranteed hereby, otherwise secured, barred by
statutes of limitation or discharged other than by payment. Landlord may
exercise rights hereunder in the event of Tenant's insolvency,
bankruptcy, receivership or assignment for benefit of creditors, in
which event all of Tenant's liabilities and indemnities to Landlord
shall be satisfied in full before Guarantor shall be entitled to
participation in the distribution of Tenant's assets. Landlord may deal
with Tenant, Guarantor and any other person liable on the indebtedness,
obligation or liabilities to Landlord as Landlord deems advisable.

6. Default of Tenant: Notice of acceptance of this Guaranty and of
defaults, breaches, demands, presentments, protest, and amendment to or
modification or cancellation of the Leases, and of any other kind is
fully waived by Guarantor. Upon default by Tenant on any of its
obligations to Landlord, then at Landlord's option, without notice or
demand upon Guarantor and without exercising any other right or remedy
Landlord may have, Landlord may proceed directly against Guarantor or
any other guarantor to enforce Landlord's rights hereunder. Without
releasing or affecting Guarantor's obligations hereunder, Landlord may
enforce any rights it may have against any persons and properties
liable.

7. Impairment of Rights: Landlord's rights shall be cumulative and not
exclusive. No impairment, limitation or modification or Tenant's
liabilities or obligations or of its trustee or receiver or any such
impairment, limitation or modification of Landlord's remedies by virtue
of the operation of bankruptcy or similar laws or decisions of any court
or courts nor any disaffirmance of the Landlord's obligations under the
Leases in such proceedings shall affect Landlord's rights against
Guarantor hereunder.

8. Successor and Assigns: The obligations of Guarantor shall inure to the
benefit of the Landlord's assigns and successors in interest in the
Leases and shall be binding upon Guarantor's heirs, successors and
assigns. Reference to Tenant herein includes any assignee of or
successor to Tenant's interest under the terms of the Leases or any
subtenant or any other party who is now or in the future may be a tenant
under any of the Leases.

9. Costs and Attorney's Fees: Guarantor shall pay all costs, expenses and
charges, including all reasonable attorneys fees, which Landlord may
incur in the enforcement of the provisions hereof. Such costs or
reasonable attorneys fees shall be payable irrespective of the Limit
Amount hereunder.

10. Notices: Any notice hereunder may be given to Guarantor by mail
addressed to:

▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇
▇▇▇▇ - ▇▇▇▇▇ ▇▇▇▇▇ ▇▇
▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇

or other address as Guarantor shall designate to Landlord in writing.

Dated this day of March, 1997.
