        delay or delays and shall, in each instance, within thirty (30) days
        after the amended Lease Commencement Date, execute and attach hereto an
        amendment in the form of that attached as Exhibit D hereto stating such
        amended Lease Commencement Date and, if applicable, an amended
        Expiration Date and no rental shall be payable by Tenant hereunder until
        the amended Lease Commencement Date. The delay in commencement of the
        Term and in the accrual of rent described in the foregoing sentence

        otherwise have by reason of the Premises not being ready for occupancy
        on the original Lease Commencement Date specified in Section 1(G) above.

        If the Premises are not ready for occupancy by Tenant on the Lease
        Commencement Date due to one or more delays caused by Tenant, or anyone
        acting under or for Tenant, Landlord shall have no liability for such
        delay and the Lease Commencement Date shall nevertheless begin as of the
        Lease Commencement Date stated in Section 1(G) (as extended only because
        of Landlord's delay pursuant to this Section 3(C), if applicable).

D.      Acceptance and Suitability. Tenant hereby agrees to accept the Premises
        in its "AS IS" condition. Tenant agrees that by taking possession of the
        Premises it will conclusively be deemed to have inspected the Premises
        and found the Premises in satisfactory condition. Tenant acknowledges
        that neither Landlord, nor any agent, employee or servant of Landlord,
        has made any representation with respect to the Premises, the Building,
        or the Project or with respect to the suitability of them for the
        conduct of Tenant's business, nor has Landlord agreed to undertake any
        modifications, alterations, or improvements of the Premises or Building,
        except as specifically provided in this Lease.

        act of Tenant, its employees, agents, contractors or invitees, which
        damage shall be repaired by Landlord at Tenant's expense. Landlord shall
        have the sole and exclusive control of the Common Areas, as well as the
        right to make changes to the Common Areas. Notwithstanding the preceding
        sentence, Landlord is not responsible for any harm or damage to any of
        Tenant's officers, agents, employees, servants, suppliers, customers or
        other invitees as a result of their use of the Common Areas. Landlord's
        rights to make changes shall include, but not be limited to, the right

        other incidents to new construction of improvements on lands adjacent or
        proximate to the Building, whether or not owned by Landlord, shall in no
        way affect this Lease or impose any liability on Landlord.

SECTION 6.  SECURITY DEPOSIT

Upon execution of this Lease, Tenant shall deposit with Landlord the Security
Deposit defined in Section 1(K) above, which shall be held by Landlord as
security for the performance by Tenant of all terms, covenants and conditions of
this Lease. It is expressly understood and agreed that such Security Deposit is
not an advance rental deposit or a measure of Landlord's damages in case of
Tenant's default. If Tenant defaults with respect to any provision of this
Lease, including, but not limited to, the provisions relating to the payment of
rent or the obligation to repair and maintain the Premises or to perform any
other term, covenant or condition contained herein, Landlord may (but shall not
be required to), without prejudice to any other remedy provided herein or
provided by law and without notice to Tenant, use the Security Deposit, or any
portion of it, to cure the default or to compensate Landlord for all damages
sustained by Landlord resulting from Tenant's default. Tenant shall immediately
on demand pay to Landlord a sum equivalent to the portion of the Security
Deposit so expended or applied by Landlord as provided in this Section so as to
maintain the Security Deposit in the sum initially deposited with Landlord.
Although the Security Deposit shall be deemed the property of Landlord, if
Tenant is not in default at the expiration or termination of this Lease,
Landlord shall return the Security Deposit (or applicable portion thereof) to
Tenant. Landlord shall not be required to keep the Security Deposit separate
from its general funds and Landlord, not Tenant, shall be entitled to all
interest, if any, accruing on any such Security Deposit. Upon any sale or
transfer of its interest in the Building, Landlord shall transfer the Security
Deposit to its successor in interest and thereupon, Landlord shall be released
from any liability or obligation with respect thereto.

        expense, obtain any and all licenses and permits necessary for any such
        use. Tenant shall not do or permit anything to be done in or about the
        Premises, Common Areas, Building or Project which will in any way

        increase the insurance risk thereon. If an increase in any fire and
        extended coverage insurance premiums paid by Landlord for the Building
        and Project is caused by Tenant's use and occupancy of the Premises,
        then Tenant shall pay as additional rental the amount of such increase
        to Landlord.

B.      Compliance with Laws. Tenant shall not use the Premises, Building,
        Project or Common Areas in any way (or permit or suffer anything to be

        ordinance or governmental rule or regulation or any covenant, condition
        or restriction (whether or not of public record) affecting the



                                       7
   8

        Premises, Project or Building, now in force or which may hereafter be
        enacted or promulgated including, but not limited to, the provisions of
        any city or county zoning codes regulating the use thereof. Tenant
        shall, at its sole cost and expense, promptly comply with (i) all laws,
        statutes, ordinances and governmental rules and regulations, now in
        force or which may hereafter be in force, applicable to Tenant or its
        use of or business or operations in the Premises including structural,
        utility system and life safety system changes necessitated by Tenant's
        acts, use of the Premises or by improvements made by or for Tenant, (ii)
        all requirements, and other covenants, conditions and restrictions, now

        force, of any board of fire underwriters or other similar body now or
        hereafter constituted relating to or affecting the condition, use or
        occupancy of the Premises, Building or Project. The judgment of any
        court of competent jurisdiction or the admission by Tenant in any action
        against Tenant, whether Landlord be a party thereto or not, that Tenant
        has violated any law, statute, ordinance, governmental rule or
        regulation or any requirement, covenant, condition or restriction shall
        be conclusive of the fact as between Landlord and Tenant. Tenant agrees
        to fully indemnify Landlord against any liability, claims or damages
        arising as a result of a breach of the provisions of this Section 8(B)
        by Tenant, and against all costs, expenses, fines or other charges
        arising therefrom, including, without limitation, reasonable attorneys'
        fees and related costs incurred by Landlord in connection therewith,
        which indemnity shall survive the expiration or earlier termination of
        this Lease. Without limiting the generality of the foregoing, it is
        expressly understood and agreed that Tenant is accepting the Premises
        "AS IS," in its present state and condition, without any representations
        or warranties from Landlord of any kind whatsoever, either express or
        implied, with respect to the Premises or the Building, including without
        limitation the compliance of the Premises or the Building with The
        Americans With Disabilities Act and the rules and regulations
        promulgated thereunder, as amended from time to time (the "ADA"). Tenant
        shall be responsible for insuring that the Premises and Tenant's use
        thereof and operations therein fully and completely comply with the ADA.
        If Tenant's use of the Premises or operations therein cause Landlord to
        incur any obligation under the ADA, as reasonably determined by
        Landlord, then Tenant shall reimburse Landlord for Landlord's costs and
        expenses in connection therewith. If Tenant's initial use of the
        Premises is not a "place of public accommodation" within the meaning of
        the ADA, then Tenant may not thereafter change the use of the Premises
        to cause the Premises to become a "place of public accommodation." In
        the event that Tenant desires or is required hereby to make Alterations
        (as defined below) to the Premises in order to satisfy its obligations
        under the ADA, then all such Alterations shall be subject to any
        requirements in this Lease with respect to Alterations of the Premises,
        and shall be performed at Tenant's sole cost and expense.

C.      Hazardous Materials.

        (1)     Tenant covenants and agrees that it shall not cause or permit
                any Hazardous Materials (as defined below) to be brought upon,
                kept, or used in or about the Premises, Building or Project by
                Tenant, its agents, employees, contractors or invitees. The
                foregoing covenant shall not extend to substances typically
                found or



                                       8
   9

                used in general office applications so long as (a) such
                substances and any equipment which generates such substances are
                maintained only in such quantities as are reasonably necessary
                for Tenant's operations in the Premises, (b) such substances are
                used strictly in accordance with the manufacturers' instructions
                therefor, (c) such substances are not disposed of in or about
                the Project in a manner which would constitute a release or
                discharge thereof, and (d) all such substances and any equipment
                which generates such substances are removed from the Project by
                Tenant upon the expiration or earlier termination of this Lease.
                Any use, storage, generation, disposal, release or discharge by
                Tenant of Hazardous Materials in or about the Project as is
                permitted pursuant to this Section shall be carried out in
                compliance with all applicable federal, state and local laws,
                ordinances, rules and regulations, including without limitation
                any labeling standards established by state regulations.
                Moreover, no hazardous waste resulting from any operations by
                Tenant shall be stored or maintained by Tenant in or about the
                Project for more than ninety (90) days prior to removal by
                Tenant. Tenant shall, annually within thirty (30) days after
                Tenant's receipt of Landlord's written request therefor, provide
                to Landlord a written list identifying any Hazardous Materials
                then maintained by Tenant in the Project, the use of each such
                Hazardous Material and the approximate quantity of each such
                Hazardous Material so maintained by Tenant, together with
                written certification by Tenant stating, in substance, that
                neither Tenant nor any person for whom Tenant is responsible has
                released or discharged any Hazardous Materials in or about the
                Project.

        (2)     In the event that Tenant proposes to conduct any use or to
                operate any equipment which will or may utilize or generate a
                Hazardous Material other than as specified in Section 8(C)(1)
                above, Tenant shall first in writing submit such use or
                equipment to Landlord for approval. No approval by Landlord
                shall relieve Tenant of any obligation of Tenant pursuant to
                this Section 8(C), including the removal, clean-up and
                indemnification obligations imposed upon Tenant by this Section
                8(C). Tenant shall, within five (5) days after receipt thereof,
                furnish to Landlord copies of all notices or other
                communications received by Tenant with respect to any actual or
                alleged release or discharge of any Hazardous Material in or
                about the Premises or the Project and shall, whether or not
                Tenant receives any such notice or communication, notify
                Landlord in writing of any discharge or release of Hazardous
                Material by Tenant or anyone for whom Tenant is responsible in
                or about the Premises or the Project. In the event that Tenant
                is required to maintain any Hazardous Materials license or
                permit in connection with any use conducted by Tenant or any
                equipment operated by Tenant in the Premises, copies of each
                such license or permit, each renewal or revocation thereof and
                any communication relating to suspension, renewal or revocation
                thereof shall be furnished to Landlord within five (5) days
                after receipt thereof by Tenant. Compliance by Tenant with the
                two immediately preceding sentences shall not relieve Tenant of
                any other obligation of Tenant pursuant to this Section 8(C).



                                       9
   10

        (3)     Upon any violation of the foregoing covenants, Tenant shall be
                obligated, at Tenant's sole cost, to clean-up and remove from
                the Project all Hazardous Materials introduced into the Project
                by Tenant or any person or entity for whom Tenant is
                responsible. Such clean-up and removal shall include all testing
                and investigation required by any governmental authorities
                having jurisdiction and preparation and implementation of any
                remedial action plan required by any governmental authorities
                having jurisdiction. All such clean-up and removal activities of
                Tenant shall, in each instance, be conducted to the satisfaction
                of Landlord and all governmental authorities having
                jurisdiction. Landlord's right of entry pursuant to Section 11
                below shall include the right to enter and inspect the Premises
                for violations of Tenant's covenants in this Section 8(C).

        (4)     Tenant shall indemnify, defend and hold harmless Landlord, and
                its successors, assigns, partners, officers, employees, agents,
                lenders and attorneys from and against any and all claims,
                liabilities, losses, actions, costs and expenses (including
                attorneys' fees and costs of defense) incurred by such
                indemnified persons, or any of them, as the result of (a) the
                introduction into or about the Project by Tenant or anyone for
                whom Tenant is responsible of any Hazardous Materials, (b) the
                usage, storage, maintenance, generation, disposition or disposal
                by Tenant or anyone for whom Tenant is responsible of Hazardous
                Materials in or about the Project, (c) the discharge or release
                in or about the Project by Tenant or anyone for whom Tenant is
                responsible of any Hazardous Materials, (d) any injury to or
                death of persons or damage to or destruction of property
                resulting from the use, introduction, maintenance, storage,
                generation, disposal, disposition, release or discharge by
                Tenant or anyone for whom Tenant is responsible of Hazardous
                Materials in or about the Project, and (e) any failure of Tenant
                or anyone for whom Tenant is responsible to observe the
                foregoing covenants of this Section 8(C).

        (5)     Upon any violation of the foregoing covenants, Landlord shall be
                entitled to exercise all remedies available to a landlord
                against a defaulting tenant, including but not limited to those
                set forth in Section 20. Without limiting the generality of the
                foregoing, Tenant expressly agrees that upon any such violation
                Landlord may, at its option, (a) immediately terminate this
                Lease or (b) continue this Lease in effect until compliance by
                Tenant with its clean-up and removal covenant notwithstanding
                any earlier expiration date of the term of this Lease. No action
                by Landlord hereunder shall impair the obligations of Tenant
                pursuant to this Section 8(C).

        (6)     As used in this Section 8(C), "Hazardous Materials" is used in
                its broadest sense and shall include any petroleum based
                products, pesticides, paints and solvents, polychlorinated
                biphenyl, lead, cyanide, DDT, acids, ammonium compounds and
                other chemical products and any substance or material defined or
                designated as hazardous or toxic, or other similar term, by any
                federal, state or local environmental statute, regulation, or
                ordinance affecting the Premises, Building or Project presently
                in effect or that may be promulgated in the future, as such

        (7)     By its signature to this Lease, Tenant confirms that it has
                conducted its own examination of the Premises and the Project
                with respect to Hazardous Materials and accepts the same "AS IS"
                and with no Hazardous Materials present thereon.

        (8)     Tenant acknowledges that incorporation of any material
                containing asbestos into the Premises is absolutely prohibited.
                Tenant agrees, represents and warrants that it shall not
                incorporate or permit or suffer to be incorporated, knowingly or
                unknowingly, any material containing asbestos into the Premises.

D.      Landlord's Rules and Regulations. Tenant shall, and Tenant agrees to
        cause its agents, servants, employees, invitees and licensees to,
        observe and comply fully and faithfully with the rules and regulations
        attached hereto as Exhibit C or such rules and regulations which may
        hereafter be adopted by Landlord (the "Rules") for the care, protection,
        cleanliness, and operation of the Premises, Building and Project, and
        any modifications or additions to the Rules adopted by Landlord,
        provided that, Landlord shall give written notice thereof to Tenant.
        Landlord shall not be responsible to Tenant for the failure of any other
        party to observe or comply with any of the Rules.

E.      Traffic and Energy Management; Recycling. Tenant agrees to cooperate and

        voluntary traffic management and recycling programs generally applicable
        to businesses located in the area in which the Project is situated or to
        the Project and, initially, shall encourage and support van and car
        pooling by employees and shall encourage and support staggered and
        flexible working hours for employees to the fullest extent permitted by
        the requirements of Tenant's business. Landlord shall offer, for the
        benefit of Tenant and other occupants of the Building and their
        respective employees only, the non-exclusive use of a shuttle service
        from the Project to a Caltrain station and a BART station at times
        designated by Landlord. Landlord shall have the option to discontinue
        such shuttle service at any time.



                                       11
   12

        Neither this Section 8(E) nor any other provision in this Lease,
        however, is intended to or shall create any rights or benefits in any
        other person, firm, company, governmental entity or the public. Landlord
        and Tenant agree to cooperate and use their best efforts to comply with
        any and all guidelines or controls imposed upon either Landlord or
        Tenant by federal or state governmental organizations or by any energy
        conservation association to which Landlord is a party concerning energy
        management. Landlord will provide recycling containers for Tenant's use
        at the Premises. Tenant agrees to use its best efforts to encourage its
        employees to recycle all recyclable material. Any costs, fees, fines or
        other levies assessed against Landlord as the result of failure of
        Tenant to comply with this Section 8(E) shall be reimbursed by Tenant to
        Landlord as additional rent.

SECTION 9.  SERVICE AND UTILITIES

A.      Standard Building Services. So long as Tenant is not in default
        hereunder (including any default of a type described in clauses (4) -
        (6) of Section 20(A) below), Landlord agrees to make available to the
        Premises, during the Building's normal business hours of 8:00 a.m. to
        6:00 p.m. Monday through Friday (holidays excepted), which hours are
        subject to change from time to time as reasonably determined by
        Landlord, such heat and air conditioning (hereinafter "HVAC"), water and
        electricity, as may be required in Landlord's judgment for the
        comfortable use and occupation of the Premises for general office
        purposes and at a level which is usual and customary in similar office
        buildings in the area where the Building is located, all of which shall
        be subject to the Rules of the Building as well as any governmental
        requirements or standards relating to, among other things, energy
        conservation.

B.      After-Hours Charges. During non-business hours Landlord shall keep the
        public areas of the Building and Project lighted and shall provide
        elevator service with at least (1) elevator, but shall not be obligated
        to furnish HVAC to the Premises. If Tenant requires HVAC during
        non-business hours, Tenant shall give Landlord at least twenty-four (24)
        hours prior notice of such requirement or shall follow such other
        procedure for activating the building energy management system as
        Landlord may advise Tenant, and Tenant shall pay Landlord for such extra
        service at Landlord's standard rates. Such rates are subject to increase
        from time to time based on increase in Landlord's costs associated with
        providing such extra services. All payments required for such charges
        shall be deemed to be additional rent and Landlord shall have the same
        remedies for a default in payment thereof as for a default in payment of
        rent. If the Building is designed for individual tenant operation of the
        HVAC, Tenant agrees to pay the cost of operating the HVAC at any time
        other than the schedule of hours for providing the same set forth above,
        which cost may include the operation of the HVAC for space located
        outside the Premises when such space is serviced concurrently with the
        operation of the HVAC for the benefit of the Premises.

C.      Limitation on Landlord's Obligations. Landlord shall not be in breach of
        its obligations under this Section 9 unless Landlord fails to make any
        repairs or perform maintenance which it is obligated to perform
        hereunder and such failure persists for an unreasonable time after
        written notice of a need for such repairs or maintenance is given to
        Landlord by



                                       12
   13

        Tenant. Landlord shall not be liable for and Tenant shall not be
        entitled to any abatement or reduction of rent by reason of Landlord's
        failure to furnish or the interruption or termination of any of the
        foregoing when such failure, interruption or termination is caused by
        accidents, breakage, repairs, strikes, brownouts, blackouts, lockouts or
        other labor disturbances or labor disputes of any character, or by any
        other cause, similar or dissimilar, beyond the actual or reasonable
        control of Landlord, nor shall such failure, interruption or termination
        under such circumstances be construed as a constructive or actual
        eviction of Tenant. Landlord shall not be liable under any circumstances
        for loss or injury to property or business, however occurring, through
        or in connection with or incidental to Landlord's failure to furnish or
        the interruption or termination of any of said service or utilities.

D.      Excess Service. Tenant shall not, without the written consent of
        Landlord, use any apparatus or device in the Premises, including,
        without limitation, electronic data processing machines, punch card
        machines or machines using in excess of one hundred twenty (120) volts
        or which consumes more electricity than is usually furnished or supplied
        for the Permitted Use of the Premises, as determined by Landlord. Tenant
        shall not consume water or electric current in excess of that usually
        furnished or supplied for the use of the Premises (as determined by
        Landlord), without first procuring the written consent of Landlord,
        which Landlord may refuse. The excess cost (including any penalties for
        excess usage) for such water and electric current shall be established
        by an estimate made by a utility company or independent engineer hired
        by Landlord at Tenant's expense and Tenant shall pay such excess costs
        each month with the Monthly Rental. All costs and expenses of modifying
        existing equipment, cables, lines, etc. or installing additional
        equipment, cables, lines, etc. to accommodate such excess usage or use
        by Tenant of such apparatus or device shall be borne by Tenant.

E.      Security Services. Certain security measures (both by electronic
        equipment and personnel) may be provided by Landlord in connection with
        the Building and Common Areas. However, Tenant hereby acknowledges that
        such security is intended to be only for the benefit of the Landlord in
        protecting its property from fire, theft, vandalism and similar perils
        and while certain incidental benefits may accrue to Tenant therefrom,
        such security is not for the purpose of protecting either the property
        of Tenant or the safety of its officers, employees, servants or
        invitees. By providing such security, Landlord assumes no obligation to
        Tenant and shall have no liability arising therefrom and Tenant hereby
        releases Landlord from all liability relating thereto. If, as a result
        of Tenant's occupancy of the Premises, Landlord in its sole discretion
        determines that it is necessary to provide security or implement
        additional security measures or devices in or about the Building or the
        Common Areas, Tenant shall be required to pay, as additional rent, the
        cost or increased cost, as the case may be, of such security.

SECTION 10.  MAINTENANCE AND REPAIRS

A.      Landlord's Obligations. Except for special or non-standard systems and
        equipment installed for Tenant's exclusive use, Landlord shall keep in
        good condition and repair, at Landlord's initial cost and expense, HVAC
        systems which service the Premises as well as



                                       13
   14

        other premises within the Building, the foundations, exterior walls,
        structural condition of interior bearing walls and roof of the Premises,
        interior walls, interior surfaces of exterior walls, ceilings, windows,
        doors, cabinets, draperies, electrical and lighting facilities within
        the Premises, window coverings, carpeting and other floor coverings,
        plate glass and skylights located within the Premises and the Building,
        as well as the parking lots, walkways, driveways, landscaping, fences,
        signs, and utility installations of the Project. Janitorial services to
        the Premises shall be provided in accordance with specifications
        established by Landlord, which specifications are subject to change from
        time to time in the reasonable discretion of Landlord. Landlord shall
        also provide elevator service, restroom supplies and window washing with
        reasonable frequency. Landlord shall not be required to make any repairs
        that are the obligation of any other tenant or occupant within the
        Building or Project or repairs for damage caused by any negligent or
        intentional act or omission of Tenant or any person claiming through or
        under Tenant or any of Tenant's employees, suppliers, shippers,
        customers or invitees, in which event Tenant shall repair such damage at
        its sole cost and expense. Tenant hereby waives and releases its right
        to make repairs at Landlord's expense under any law, statute, ordinance,
        rule or regulation now or hereafter in effect in any jurisdiction in
        which the Project is located.

B.      Tenant's Obligations. Tenant shall, at its sole cost and expense, make
        all repairs and replacements as and when Landlord deems reasonably
        necessary to preserve in good working order and condition any special or
        supplementary HVAC systems located within the Premises and installed for
        the exclusive use of the Premises, Tenant's cabling and telephone lines
        and all other non-standard utility facilities and systems exclusively
        serving the Premises, and all of Tenant's trade fixtures located within
        the Premises; provided, however, at Tenant's written request, Landlord
        will maintain such non-standard improvements at Tenant's expense, at a
        cost or charge equal to the costs incurred in such maintenance plus an
        additional overhead charge of fifteen percent (15%). Tenant shall not
        commit or permit any waste in or about the Premises, the Building or the
        Project. Tenant shall reimburse Landlord on demand for all repairs to
        the Premises, Building and Project which are required, in the reasonable
        opinion of Landlord, as a result of any misuse, neglect, negligent or
        intentional act or omission committed or permitted by Tenant or by any
        subtenant, agent, employee, supplier, shipper, customer, invitee or
        servant of Tenant.

C.      Landlord's Right to Make Repairs. In the event that Tenant fails to
        maintain the Premises in good and sanitary order, condition and repair
        as required by this Lease, then, following written notification to
        Tenant (except in the case of an emergency, in which case no prior
        notification shall be required), Landlord shall have the right, but not
        the obligation, to enter the Premises and to do such acts and expend
        such funds at the expense of Tenant as are required to place the
        Premises in good, safe and sanitary order, condition and repair. Any
        amount so expended by Landlord plus an overhead charge of fifteen
        percent (15%) of the expended amount shall be paid by Tenant promptly
        upon demand as additional rent.

D.      Condition of Premises Upon Surrender. Except as otherwise provided in
        this Lease, Tenant shall, upon the expiration or earlier termination of
        the Term, surrender the



                                       14
   15

        Premises to Landlord in the same condition as on the date Tenant took
        possession, reasonable wear and tear excepted. All appurtenances,
        fixtures, improvements, additions and other property attached to or
        installed in the Premises whether by Landlord or by or on behalf of
        Tenant, and whether at Landlord's expense or Tenant's expense, shall be
        and remain the property of Landlord unless Landlord specifically agrees
        otherwise in writing. Any furnishings and personal property of Tenant
        located in the Premises, whether the property of Tenant or leased by
        Tenant (including the fixtures, improvements and other items agreed, in
        writing, by Landlord to belong to the Tenant as provided in the
        preceding sentence and, unless Landlord elects to require Tenant to
        leave the same in the Premises, which Landlord shall have the right to
        do, all data, telephone or other cabling or wiring installed by or on
        behalf of Tenant in the Premises, including the plenum area above the
        ceiling of the Premises), shall be and remain the property of Tenant and
        shall be removed by Tenant at Tenant's sole cost and expense at the
        expiration of the Term. Tenant shall promptly repair any damage to the
        Premises or the Building resulting from such removal. Any of Tenant's
        property not removed from the Premises upon the expiration of the Term
        shall, at Landlord's option, either become the property of Landlord or
        may be removed by Landlord and Tenant shall pay to Landlord the cost of
        such removal within ten (10) days after delivery of a bill therefor or
        Landlord, at its option, may deduct such amount from the Security
        Deposit. Any damage to the Premises, including any structural damage,
        resulting from Tenant's use or from the removal of Tenant's fixtures,
        furnishings and equipment, shall be repaired by Tenant at Tenant's
        expense.

SECTION 11.  ENTRY BY LANDLORD

Landlord reserves and shall at any and all times have the right to enter the
Premises at reasonable times during normal business hours and at any time in
case of an emergency to inspect the same to determine whether Tenant is
complying with its obligations hereunder; to supply janitorial service and any
other service to be provided by Landlord hereunder; and, upon reasonable notice
to Tenant, may exhibit the Premises to prospective purchasers, mortgagees or
prospective tenants; to post notices of nonresponsibility; and to alter, improve
or repair the Premises and any portion of the Building and Project, without
abatement of rent, and may for that purpose erect scaffolding and other
necessary structures that are reasonably required by the character of the work
to be performed by Landlord, provided that the business of Tenant shall not be
interfered with unreasonably. For each of the aforesaid purposes, Landlord shall
at all times have and retain a key with which to unlock all of the doors in,
upon and about the Premises, excluding Tenant's vaults and safes, and Landlord
shall have the right to use any and all means which Landlord may deem proper to
open such doors in the event of an emergency. Any entry to the Premises or
portions thereof obtained by Landlord by any of said means, or otherwise, shall
not under any circumstances be construed or deemed to be a forcible or unlawful
entry into, or a detainer of, the Premises, or an eviction, actual or
constructive, of Tenant from the Premises, or any portion thereof. Tenant hereby
waives any claim for damages for any injury or inconvenience to or interference
with Tenant's business and any loss of occupancy or quiet enjoyment of the
Premises by reason of Landlord's exercise of its right of entry in accordance
with this Section 11, and Tenant shall not be entitled to an abatement or
reduction of rent in connection therewith.



                                       15
   16

SECTION 12.  ALTERATIONS, ADDITIONS AND TRADE FIXTURES

Except to the extent provided for in Exhibit B hereto, Tenant shall not make any
alterations, additions or improvements to the Premises, or any part thereof,
whether structural or nonstructural (hereafter "Alterations"), without
Landlord's prior written consent. If Tenant does not use Landlord's architect or
contractor to design or perform Alterations, Tenant shall pay to Landlord, as
additional rent, a management fee equal to ten percent (10%) of the cost of the
Alterations plus any professional fees or other costs and expenses incurred by
Landlord in reviewing such plans and specifications or inspecting progress of
any such work. In order to obtain Landlord's preliminary consent, which
preliminary consent may be given or denied in Landlord's sole discretion, Tenant
shall submit such information as Landlord may require, including without
limitation plans and specifications for the Alterations. After Landlord gives
preliminary consent, in order to obtain Landlord's final consent, which consent
may not be unreasonably withheld, Tenant shall then submit (a) permits,
licenses, bonds, and the construction contract, all in conformance with the
plans and specifications preliminarily approved by Landlord; (b) evidence of
insurance coverage in such types and amounts and from such insurers as Landlord
deems satisfactory; and (c) such other information as Landlord deems reasonably
necessary. The construction contract shall, at a minimum, require the general
contractor and all subcontractors to obey the rules and regulations of the
Building and Project. All Alterations shall be done in a good workmanlike manner
by qualified and licensed contractors or mechanics, as approved by Landlord.
Except for Alterations to the Premises, Tenant shall have no right whatsoever to
make any alterations or modifications to any portion of the Building or its
appurtenant facilities nor shall any Alterations affect the structure of the
Building or its exterior appearance. All Alterations made by or for Tenant
(other than Tenant's moveable trade fixtures), shall, unless Landlord expressly
requires or agrees otherwise in writing, immediately become the property of
Landlord, without compensation to Tenant, but Landlord has no obligation to
repair, maintain or insure those Alterations. Carpeting, shelving and cabinetry
are considered improvements of the Premises and not movable trade fixtures,
regardless of how or where affixed. No Alterations will be removed by Tenant
from the Premises either during or at the expiration or earlier termination of
the Term, and they shall be surrendered as a part of the Premises unless
Landlord has required that Tenant remove them. At Landlord's discretion,
Alterations are subject to removal by Tenant and at Tenant's sole cost and
expense. Upon any such removal, Tenant shall repair any damage caused to the
Premises thereby, and shall return the Premises to the condition they were in
prior to installation of such Alterations so removed. Tenant shall indemnify,
defend and keep Landlord free and harmless from and against all liability, loss,
damage, cost, attorneys' fees and any other expense incurred on account of
claims by any person performing work or furnishing materials or supplies for
Tenant or any person claiming under Tenant. Landlord may require Tenant to
provide Landlord, at Tenant's sole cost and expense, a lien and completion bond
in an amount equal to one and one-half times the estimated cost of such
improvements, to insure Landlord against any liability for mechanic's liens and
to insure completion of the work. Landlord shall have the right at all times to
post on the Premises any notices permitted or required by law, or that Landlord
shall deem proper, for the protection of Landlord, the Premises, the Building
and the Project, and any other party having an interest therein, from mechanics'
and materialmen's liens, and Tenant shall give to Landlord written notice of the
commencement of any construction in or on the Premises at



                                       16
   17

least thirty (30) days prior thereto. Prior to the commencement of any such
construction, Landlord shall be furnished certificates of insurance, naming
Landlord as an additional insured, evidencing that each contractor performing
work has insurance acceptable to Landlord, including but not limited to general
liability insurance of not less that Two Million Dollars ($2,000,000.00) and
worker's compensation insurance in the statutorily required amount.

SECTION 13.  MECHANIC'S LIENS

Tenant shall keep the Premises, the Building and the Project free from any liens
arising out of any work performed, material furnished or obligation incurred by
or for Tenant or any person or entity claiming through or under Tenant. In the
event that Tenant shall not, within ten (10) days following the imposition of
any such lien, cause the same to be released of record by payment or posting of
a proper bond, Landlord shall have, in addition to all other remedies provided
herein and by law, the right, but not the obligation, to cause such lien to be
released by such means as Landlord deems proper, including payment of the claim
giving rise to such lien. All such sums paid and all expenses incurred by
Landlord in connection therewith shall be due and payable to Landlord by Tenant
on demand.

SECTION 14.  INSURANCE

A.      Tenant. During the Term hereof, Tenant shall keep in full force and
        effect the following insurance and shall provide appropriate insurance
        certificates to Landlord prior to the Lease Commencement Date and
        annually thereafter before the expiration of each policy:

        (1)     Commercial general liability insurance for the benefit of Tenant
                and Landlord as an additional insured, with a limit of not less
                than Two Million Dollars ($2,000,000.00) combined single limit
                per occurrence, against claims for personal injury liability
                including, without limitation, bodily injury, death or property
                damage liability and covering (a) the business(es) operated by
                Tenant and by any subtenant of Tenant on the Premises, (b)
                operations of independent contractors engaged by Tenant for
                services or construction on or about the Premises, and (c)
                contractual liability;

        (2)     All risk property insurance, insuring the personal property,
                furniture, furnishings and fixtures belonging to Tenant located
                on the Premises for not less than one hundred percent (100%) of
                the actual replacement value thereof;

        (3)     Workers' compensation in the amount required by law; and

        (4)     Business interruption or loss of income insurance in amounts
                satisfactory to Landlord, with a rental interruption rider
                assuring Landlord that the rent due hereunder will be paid for a
                period of not less than twelve (12) months or the remaining term
                of this Lease, whichever is shorter, if the Premises are
                destroyed or rendered inaccessible by a risk insured against by
                a policy of all risk insurance.

        Each insurance policy obtained by Tenant pursuant to this Lease shall
        contain a clause



                                       17
   18

        that the insurer will provide Landlord with at least thirty (30) days'
        prior written notice of any material change, non-renewal or cancellation
        of the policy, shall be in a form satisfactory to Landlord and shall be
        taken out with an insurance company authorized to do business in the
        State in which the Project is located and rated not less than Best's
        Financial Class X and Best's Policy Holder Rating "A". In addition, any
        insurance policy obtained by Tenant shall be written as a primary
        policy, and shall not be contributing with or in excess of any coverage
        which Landlord may carry. The liability limits of the above described
        insurance policies shall in no manner limit the liability of Tenant
        under the terms of Section 15 below.

        Not more frequently than every two (2) years, if, in the reasonable
        opinion of Landlord, the amount of liability insurance specified in this
        Section 14 is not adequate, the above-described limits of coverage shall
        be adjusted by Landlord, by written notification to Tenant, in order to
        maintain the level of insurance protection at least equal to the
        protection afforded on the date the Term commences. If Tenant fails to
        maintain and secure the insurance coverage required under this Section
        14, then Landlord shall have, in addition to all other remedies provided
        herein and by law, the right, but not the obligation, to procure and
        maintain such insurance, the cost of which shall be due and payable to
        Landlord by Tenant on demand.

        If, on account of the failure of Tenant to comply with the provisions of
        this Section, Landlord is deemed a co-insurer by its insurance carrier,
        then any loss or damage which Landlord shall sustain by reason thereof
        shall be borne by Tenant and shall be immediately paid by Tenant as
        additional rent upon receipt of a bill therefor and evidence of such
        loss.

B.      Landlord. During the Term hereof, Landlord shall keep in full force and
        effect the following insurance:

        (1)     All risk property insurance (including flood and earthquake)
                insuring the Building and Landlord's improvements in an amount
                not less than the full replacement cost thereof; and

        (2)     Such other insurance as Landlord deems necessary in its sole and
                absolute discretion.

        All insurance policies shall be issued in the names of Landlord and
        Landlord's lender, if any, and any other party reasonably designated by
        Landlord as an additional insured, as their interests appear. The
        insurance policies shall provide that any proceeds shall be made payable
        to Landlord, or to the holders of mortgages or deeds of trust
        encumbering Landlord's interest in the Premises, Building, and Project,
        or to any other party reasonably designated by Landlord as an additional
        insured, as their interests shall appear.

C.      Waiver of Subrogation. Landlord and Tenant each hereby waives any and
        all rights of recovery against the other, and against any other tenant
        or occupant of the Building and



                                       18
   19

        against the officers, employees, agents, representatives, customers and
        business visitors of such other party and of each such other tenant or
        occupant of the Building, for loss of or damage to such waiving party or
        its property or the property of others under its control, arising from
        any cause insured against under any policy of property insurance
        required to be carried by such waiving party pursuant to the provisions
        of this Lease (or any other policy of property insurance carried by such
        waiving party in lieu thereof) at the time of such loss or damage. The
        foregoing waiver shall be effective whether or not a waiving party
        actually obtains and maintains such insurance which such waiving party
        is required to obtain and maintain pursuant to this Lease (or any
        substitute therefor). Landlord and Tenant shall, upon obtaining the
        policies of insurance which they are required to maintain hereunder,
        give notice (if required) to their respective insurance carrier or
        carriers that the foregoing mutual waiver of subrogation is contained in
        this Lease.

SECTION 15.  INDEMNITY

A.      Indemnification by Tenant. Tenant agrees to indemnify, defend and hold
        Landlord and its officers, directors, partners, agents and employees
        (collectively, "Indemnitees") entirely harmless from and against all
        liabilities, losses, demands, actions, expenses or claims, including
        reasonable attorneys' fees and court costs, for injury to or death of
        any person or for damages to any property or for violation of law
        arising out of or in any manner connected with (i) the use, occupancy or
        enjoyment of the Premises, Building or Project by Tenant or Tenant's
        agents, employees, invitees or contractors (the "Tenant's Agents") or
        any work, activity or other things allowed or suffered by Tenant or
        Tenant's Agents to be done in or about the Premises, Building or
        Project, (ii) any breach or default in the performance of any obligation
        of Tenant under this Lease, and (iii) any act or failure to act, whether
        negligent or otherwise tortious, by Tenant or Tenant's Agents in or
        about the Premises, Building or Project; provided, however, that Tenant
        shall not be required to indemnify Landlord in respect of any loss or
        damage arising by reason of the gross negligence or willful misconduct
        of Landlord.

B.      Limitation on Landlord's Liability; Release of Directors, Officers and
        Partners of Landlord. Tenant agrees that, in the event Tenant shall have
        any claim against Landlord under this Lease arising out of the subject
        matter of this Lease, Tenant's sole recourse shall be against the
        Landlord's interest in the Building, for the satisfaction of any claim,
        judgment or decree requiring the payment of money by Landlord as a
        result of a breach hereof or otherwise in connection with this Lease,
        and no other property or assets of Landlord, its officers, directors,
        employees, successors or assigns, shall be subject to the levy,
        execution or other enforcement procedure for the satisfaction of any
        such claim, judgment, injunction or decree. MOREOVER, TENANT AGREES THAT
        LANDLORD SHALL IN NO EVENT AND UNDER NO CIRCUMSTANCES BE RESPONSIBLE FOR
        ANY CONSEQUENTIAL, SPECIAL, INCIDENTAL OR PUNITIVE DAMAGES INCURRED OR
        SUSTAINED BY TENANT, OR ITS EMPLOYEES, AGENTS, CONTRACTORS OR INVITEES
        AS A RESULT OF OR IN ANY WAY CONNECTED TO TENANT'S OCCUPANCY OF THE
        PREMISES. None of the Indemnitees shall be liable to Tenant for, and, as
        such assumption and waiver do not



                                       19
   20

        violate public policy, Tenant assumes all risk of, and waives any and
        all right to assert claims against, or obtain any damages from, the
        Indemnitees with respect to, loss, injury, or damages which may be
        sustained by the person, goods, wares, merchandise or property of
        Tenant, Tenant's Agents, or any other person in or about the Premises
        from any cause whatsoever, whether such damage or injury results from
        conditions arising within the Premises or from other sources and whether
        known, unknown, foreseen, unforeseen, patent or latent. Tenant
        understands and acknowledges the significance and consequence of such
        specific assumption of risk and waiver.

C.      No Landlord Liability for Force Majeure Events. Landlord shall not be
        liable or responsible to Tenant for any loss or damage to any property
        or person occasioned by theft, fire, act of God, public enemy,
        injunction, riot, strike, insurrection, war, court order, requisition,
        or order of governmental body or authority, or for any damage or
        inconvenience that may arise through repair or alteration of any part of
        the Project, the Building or the Premises, or a failure to make any such
        repairs, except as expressly provided in this Lease.

D.      Indemnification by Landlord. Landlord shall indemnify, defend, protect
        and save Tenant harmless from all losses, costs, damages, claims and
        liability whatsoever on account of any damage or liability of any kind
        or for any injury to or death of persons arising in the Common Areas if
        caused by or resulting from any negligent or willful act or omission of
        Landlord or its employees or agents; provided, however, that Landlord's
        obligation to indemnify and hold harmless Tenant pursuant to the
        foregoing provisions is made for the purpose of providing any benefit
        from time to time available to Tenant under policies of insurance
        carried by Landlord, and further provided that the foregoing provisions
        shall in no event require Landlord to provide any defense to Tenant or
        pay any sum to or on behalf of Tenant in addition to that which may be
        provided and paid pursuant to such policies of insurance as may be
        carried by Landlord from time to time.

SECTION 16.  ASSIGNMENT AND SUBLETTING BY TENANT

A.      Consent Required. Tenant shall not, directly or indirectly, voluntarily
        or by operation of law, sell, assign, encumber, pledge or otherwise
        transfer or hypothecate all or any part of the Premises or Tenant's
        leasehold estate hereunder (collectively "Assignment"), or permit the
        Premises to be occupied by anyone other than Tenant or sublet the
        Premises ("Sublease") or any portion thereof without Landlord's prior
        written consent being had and obtained in each instance, subject to the
        terms and conditions contained in this Section. In no event will
        Landlord's consent be unreasonably withheld. Any sale or other transfer,
        including transfer by consolidation, merger or reorganization, of
        twenty-five percent (25%) or more of the voting stock of Tenant, if
        Tenant is a corporation, or any sale or other transfer of twenty-five
        percent (25%) or more of the partnership interest in Tenant, if Tenant
        is a partnership, shall be an Assignment for purposes of this Section.
        As used in this subsection, the term "Tenant" shall also mean any entity
        that has guaranteed Tenant's obligation under this Lease, and the
        prohibition hereof shall be applicable to any sales or transfers of
        stock or partnership interests of said guarantor.



                                       20
   21

B.      Tenant's Request for Consent. If Tenant desires at any time to enter
        into an Assignment of this Lease or a Sublease of the Premises or any
        portion thereof, Tenant shall request, in writing, at least sixty (60)
        days prior to the effective date of the Assignment or Sublease,
        Landlord's consent to the Assignment or Sublease, and shall provide
        Landlord with the following information:

        (1)     The name of the proposed assignee, subtenant or occupant;

        (2)     The nature of the proposed assignee's, subtenant's or occupant's
                business to be carried on in the Premises;

        (3)     The terms and provisions of the proposed Assignment or Sublease
                and a copy of such documents; and

        (4)     Such financial information concerning the proposed assignee,
                subtenant or occupant which Landlord shall have requested
                following its receipt of Tenant's request for consent.

C.      Landlord's Election. At any time within fifteen (15) business days after
        Landlord's receipt of the notice specified above, Landlord may by
        written notice to Tenant elect either to (1) consent to the proposed
        Assignment or Sublease, (2) refuse to consent to the proposed Assignment
        or Sublease, or (3) terminate this Lease in full with respect to an
        Assignment or terminate in part with respect to a Sublease. Any such
        termination of this Lease shall be conditioned on Landlord successfully
        entering into a new lease covering the Premises or a portion thereof
        with the intended assignee or subtenant on such terms as Landlord and
        such person may agree, or entering into a new lease covering the
        Premises or a portion thereof with any other person. In such event,
        Tenant shall not be entitled to any portion of the profit, if any, which
        Landlord may realize on account of such termination and reletting.
        Landlord's exercise of its aforesaid option shall not be construed to
        impose any liability upon Landlord with respect to any real estate
        brokerage commission(s) or any other proposed subletting or assignment.

D.      Landlord's Factors. Landlord and Tenant agree (by way of example and
        without limitation) that Landlord shall be entitled to take into account
        any fact or factor which Landlord reasonably deems relevant to its
        decision to consent or not consent to an Assignment or Sublease,
        including but not necessarily limited to the following, all of which
        Tenant hereby agrees are reasonable factors for Landlord's
        consideration:

        (1)     The financial strength of the proposed assignee or subtenant
                (which shall be at least equal to that of Tenant as of the date
                of execution of this Lease), including the adequacy of its
                working capital to pay all expenses anticipated in connection
                with any remodeling of the Premises.

        (2)     The quality and nature of the business and/or services to be
                conducted in or from the Premises by the proposed assignee or
                subtenant and in any other locations which it has.



                                       21
   22

        (3)     Violation of exclusive use rights previously granted by Landlord
                to other tenants of the Building.

        (4)     The quality of the appearance of the Premises resulting from any
                remodeling or renovation to be conducted by the proposed
                assignee or subtenant, and the compatibility of such quality
                with that of other premises in the Building.

        (5)     Whether the business in the Premises is, and whether the
                business to be operated by the proposed assignee or subtenant
                will be, a "destination business" (i.e., a business which draws
                patrons to the Building specifically to obtain services from
                such business).

        (6)     Whether the proposed tenant is a direct competitor of Landlord.

        (7)     Whether there then exists any default by Tenant pursuant to this
                Lease or any non-payment or non-performance by Tenant under this
                Lease which, with the passage of time and/or the giving of
                notice, would constitute a default under this Lease.

        Moreover, Landlord shall be entitled to be reasonably satisfied that
        each and every covenant, condition or obligation imposed upon Tenant by
        this Lease and each and every right, remedy or benefit afforded Landlord
        by this Lease is not impaired or diminished by such Assignment or
        Sublease. In no event shall there be any substantial change in the use
        of the Premises in connection with any Assignment or Sublease except as
        expressly approved in writing by Landlord in advance. Landlord and
        Tenant acknowledge that the express standards and provisions set forth
        in this Lease dealing with Assignment and Sublease, including those set
        forth in Sections 16(E) through 16(H) have been freely negotiated and
        are reasonable at the date hereof taking into account Tenant's proposed
        use of the Premises and the nature and quality of the Building and
        Project. No withholding of consent by Landlord for any reason deemed
        sufficient by Landlord shall give rise to any claim by Tenant or any
        proposed assignee or subtenant or entitle Tenant to terminate this Lease
        or to any abatement of rent. Approval of any Assignment of Tenant's
        interest shall, whether or not expressly so stated, be conditioned upon
        such assignee assuming in writing all obligations of Tenant hereunder by
        a written instrument satisfactory to Landlord.

E.      Granting of Consent. If Landlord consents to the Sublease or Assignment
        within said thirty (30) day period, Tenant may enter into such
        Assignment or Sublease of the Premises or portion thereof, but only upon
        the terms and conditions set forth in the notice furnished by Tenant to
        Landlord pursuant to Section 16(B) above.

F.      Assignment and Sublease Profit. In connection with any Assignment or
        Sublease, as a condition to Landlord's consent, seventy-five percent
        (75%) of any sums or other economic consideration received by Tenant
        directly or indirectly in connection with any assignment or sublease
        hereunder (except to the extent of assignment or sublease



                                       22
   23

        commissions paid by Tenant to a licensed broker at prevailing rates for
        comparable space) from assignee or sublessee and leasehold improvement
        costs whether described as rental or otherwise which exceed, in the
        aggregate, the total sums which Tenant is obligated to pay Landlord
        hereunder (prorated to reflect obligations allocable to that portion of
        the Premises assigned or sublet) shall be payable to Landlord as
        additional rent under this Lease. Within fifteen (15) days after written
        request therefor by Landlord, Tenant shall at any time and from time to
        time at Landlord's request certify to Landlord the amount of all such
        sums or other economic consideration received and all such commissions
        and improvement costs incurred, or expected to be received or incurred.

G.      Tenant Remains Liable. No consent by Landlord to any Assignment or
        Sublease by Tenant shall relieve Tenant of any obligation to be
        performed by Tenant under this Lease, whether arising before or after
        the Assignment or Sublease. The consent by Landlord to any Assignment or
        Sublease shall not relieve Tenant of the obligation to obtain Landlord's
        express written consent to any other Assignment or Sublease. Any
        Assignment or Sublease that is not in compliance with this Section 16
        shall be void and, at the option of Landlord, shall constitute a
        material default by Tenant under this Lease. The acceptance of rent by
        Landlord or payment to Landlord of any other monetary obligation by a
        proposed assignee or sublessee shall not constitute the consent by
        Landlord to such Assignment or Sublease. Tenant shall promptly provide
        to Landlord a copy of the fully executed Sublease or Assignment.

H.      Assignee Becomes Liable. Each assignee, sublessee or other transferee,
        other than Landlord, shall assume, as provided in this Section 16(H),
        all obligations of Tenant under this Lease and shall be and remain
        liable jointly and severally with Tenant for the payment of Monthly
        Rental and all other monetary obligations hereunder, and for the
        performance of all the terms, covenants, conditions and agreements
        herein contained on Tenant's part to be performed for the Term;
        provided, however, that the assignee, sublessee, or other transferee
        shall be liable to Landlord for rent only in the amount set forth in the
        Assignment or Sublease. No Assignment shall be binding on Landlord
        unless the assignee or Tenant shall deliver to Landlord a counterpart of
        the Assignment and an instrument in recordable form that contains a
        covenant of assumption by the assignee satisfactory in substance and
        form to Landlord, consistent with the requirements of this Section 16(H)
        but the failure or refusal of the assignee to execute such instrument of
        assumption shall not release or discharge the assignee from its
        liability as set forth above.

I.      Bankruptcy. If this Lease is assigned to any person or entity pursuant
        to the provisions of the Bankruptcy Code, 11 U.S.C. Section 101 et seq.,
        (the "Bankruptcy Code"), any and all monies or other consideration
        payable or otherwise to be delivered in connection with such assignment
        shall be paid or delivered to Landlord, shall be and remain the
        exclusive property of Landlord and shall not constitute property of
        Tenant or of the estate of Tenant within the meaning of the Bankruptcy
        Code. Any and all monies or other considerations constituting Landlord's
        property under the preceding sentence not paid or delivered to Landlord
        shall be held in trust for the benefit of Landlord and be promptly paid
        or delivered to Landlord. Any person or entity to which this Lease is
        assigned pursuant to the provisions of the Bankruptcy Code, shall be
        deemed, without further act or deed, to



                                       23
   24

        have assumed all of the obligations arising under this Lease on and
        after the date of such Assignment. Any such assignee shall upon demand
        execute and deliver to Landlord an instrument confirming such
        assumption.

J.      Landlord's Fees. Tenant shall pay Landlord's expenses and attorneys'
        fees incurred in processing an Assignment or Sublease, but in no event
        less than Five Hundred Dollars ($500.00) for each such proposed transfer
        to cover the legal review and processing expenses of Landlord, whether
        or not Landlord shall grant its consent to such proposed transfers.

K.      Certain Rights Personal to Tenant. All options to extend, renew or
        expand, if any, contained in this Lease are personal to Tenant. Consent
        by Landlord to any Assignment or Sublease shall not include consent to
        the assignment or transfer of any such rights with respect to the
        Premises or any special privileges or extra services granted to Tenant
        by this Lease, or any addendum or amendment hereto or letter of
        agreement. All such options, rights, privileges and extra services shall
        terminate upon the effective date of such Assignment or Sublease unless
        Landlord specifically grants in writing such options, rights, privileges
        and extra services to such assignee or subtenant. Similarly, any
        allowance, abatement or monetary concession provided to Tenant as an
        inducement to execute this Lease is personal to Tenant and shall be
        amortized (on a straight line basis) over the term of this Lease. Upon
        the effective date of any Assignment or Sublease, the then unamortized
        portion thereof shall be paid by Tenant to Landlord in cash on or before
        the effective date of such Assignment or Sublease.

L.      Sublease Rents. Tenant immediately and irrevocably assigns to Landlord,
        as security for Tenant's obligations under this Lease, all rent from any
        subletting of all or part of the Premises, and appoints Landlord, as
        assignee and as attorney-in-fact for Tenant for purposes hereof.
        Landlord, or a receiver for Tenant appointed on Landlord's application,
        may collect such rents and apply same toward Tenant's obligations under
        this Lease; except that, until the occurrence of an act of default by
        Tenant, Tenant shall have the right and license to collect such rents.

SECTION 17.  TRANSFER OF LANDLORD'S INTEREST

In the event Landlord shall sell or otherwise convey its title to the Building,
then, after the effective date of such sale or conveyance, Landlord shall have
no further liability under this Lease to Tenant except as to matters of
liability which have accrued and are unsatisfied as of the date of sale or
conveyance, and Tenant shall seek performance solely from Landlord's purchaser
or successor in title. In connection with such sale or transfer, Landlord may
assign its interest under this Lease without notice to or consent by Tenant. In
such event, Tenant agrees to be bound to any successor Landlord.

SECTION 18.  DAMAGE AND DESTRUCTION

A.      Minor Insured Damage. In the event the Premises or the Building, or any
        portion thereof, is damaged or destroyed by any casualty that is covered
        by the insurance maintained by



                                       24
   25

        Landlord pursuant to Section 14 above, then Landlord shall rebuild,
        repair and restore the damaged portion thereof, provided that (1) the
        amount of insurance proceeds available to Landlord equals or exceeds the
        cost of such rebuilding, restoration and repair, (2) such rebuilding,
        restoration and repair can be completed within one hundred eighty (180)
        days after the work commences in the opinion of a registered architect
        or engineer appointed by Landlord, (3) the damage or destruction has
        occurred more than twelve (12) months before the expiration of the Term,
        and (4) such rebuilding, restoration or repair is then permitted, under
        applicable governmental laws, rules and regulations, to be done in such
        a manner as to return the damaged portion thereof to substantially its
        condition immediately prior to the damage or destruction, including,
        without limitation, substantially the same Rentable Area on each of the
        damaged floors. To the extent that insurance proceeds must be paid to a
        mortgagee or beneficiary under, or must be applied to reduce any
        indebtedness secured by, a mortgage or deed of trust encumbering the
        Premises, Building or Project, such proceeds, for the purposes of this
        Section 18(A), shall be deemed not available to Landlord unless such
        mortgagee or beneficiary permits Landlord to use such proceeds for the
        rebuilding, restoration and repair of the damaged portion thereof.
        Notwithstanding the foregoing, Landlord shall have no obligation to
        repair any damage to, or to replace any of, Tenant's personal property,
        furnishings, trade fixtures, equipment or other such property or effects
        of Tenant.

B.      Major or Uninsured Damage. In the event the Premises or the Building, or
        any portion thereof, is damaged or destroyed by any casualty to the
        extent that Landlord is not obligated, under Section 18(A) above, to
        rebuild, repair or restore the damaged portion thereof, then Landlord
        shall, within sixty (60) days after such damage or destruction, notify
        Tenant of its election, at its option, to either (1) rebuild, restore
        and repair the damaged portions thereof, in which case Landlord's notice
        shall specify the time period within which Landlord estimates such
        repairs or restoration can be completed; or (2) terminate this Lease
        effective as of the date the damage or destruction occurred. If Landlord
        does not give Tenant written notice within sixty (60) days after the
        damage or destruction occurs of its election to rebuild or restore and
        repair the damaged portions thereof, Landlord shall be deemed to have
        elected to terminate this Lease.

C.      Abatement of Rent. There shall be an abatement of rent by reason of
        damage to or destruction of the Premises or the Building, or any portion
        thereof, to the extent that Landlord receives insurance proceeds for
        loss of rental income attributable to the Premises, commencing on the
        date that the damage to or destruction of the Premises or Building has
        occurred. Such abatement shall be determined by reference to the area of
        the Premises rendered untenantable, except that if so much of the
        Premises shall be untenantable that it is not commercially practicable
        for Tenant to use any portion thereof, rent shall entirely abate during
        restoration of the casualty.

D.      Waiver. Tenant shall have no claim against Landlord for any damage
        suffered by Tenant by reason of any such damage, destruction, repair or
        restoration. Tenant waives the provisions of California Civil Code
        Sections 1932(2) and 1933(4) and any present or future laws or case
        decisions to the same effect. Upon completion of such repair or
        restoration, Tenant shall promptly refixture the Premises substantially
        to the condition



                                       25
   26

        they were in prior to the casualty and shall reopen for business if
        closed by the casualty.

SECTION 19.  CONDEMNATION

A.      Total or Partial Taking. If all or substantially all of the Premises is
        condemned or taken in any manner for public or quasi-public use,
        including but not limited to, a conveyance or assignment in lieu of the
        condemnation or taking, this Lease shall automatically terminate as of
        the earlier of the date on which actual physical possession is taken by
        the condemnor or the date of dispossession of Tenant as a result of such
        condemnation or other taking. If less than all or substantially all of
        the Premises is so condemned or taken, this Lease shall automatically
        terminate only as to the portion of the Premises so taken as of the
        earlier of the date on which actual physical possession is taken by the
        condemnor or the date of dispossession of Tenant as a result of such
        condemnation or taking. If a portion of the Building not including the
        Premises is condemned or otherwise taken so as to require, in the
        opinion of Landlord, a substantial alteration or reconstruction of the
        remaining portions thereof, this Lease may be terminated by Landlord, as
        of the date on which actual physical possession is taken by the
        condemnor or dispossession of Tenant as a result of such condemnation or
        taking, by written notice to Tenant delivered within sixty (60) days
        following notice to Landlord of the date on which such physical
        possession is taken or dispossession will occur.

B.      Award. Landlord shall be entitled to the entire award in any
        condemnation proceeding or other proceeding for taking for public or
        quasi-public use, including, without limitation, any award made for the
        value of the leasehold estate created by this Lease. No award for any
        partial or total taking shall be apportioned, and Tenant hereby assigns
        to Landlord any award that may be made in such condemnation or other
        taking, together with any and all rights of Tenant now or hereafter
        arising in or to the same or any part thereof. Although all damages in
        the event of any condemnation are to belong to Landlord whether such
        damages are awarded as compensation for diminution in value of the
        leasehold or to the fee of the Premises, Tenant shall have the right to
        claim and recover from the condemnor, but not from Landlord, such
        compensation as may be separately awarded or recoverable by Tenant in
        Tenant's own right on account of damages to Tenant's business by reason
        of the condemnation and for or on account of any cost or loss to which
        Tenant might be put in removing Tenant's merchandise, furniture and
        other personal property, fixtures, and equipment, for the interruption
        of or damage to Tenant's business or for Tenant's relocation expenses.

C.      Abatement in Rent. In the event of a partial condemnation or other
        taking that does not result in a termination of this Lease as to the
        entire Premises pursuant to this Section 19, the rent and all other
        charges shall abate in proportion to the portion of the Premises taken
        by such condemnation or other taking. If this Lease is terminated, in
        whole or in part, pursuant to any of the provisions of this Section 19,
        all rentals and other charges payable by Tenant to Landlord hereunder
        and attributable to the Premises taken shall be paid up to the date upon
        which actual physical possession shall be taken by the condemnor.
        Landlord shall be entitled to retain all of the Security Deposit until
        such time as this Lease is terminated as to all of the Premises.



                                       26
   27

D.      Temporary Taking. If all or any portion of the Premises is condemned or
        otherwise taken for public or quasi-public use for a limited period of
        time, this Lease shall remain in full force and effect and Tenant shall
        continue to perform all terms, conditions and covenants of this Lease;
        provided, however, the rent and all other charges payable by Tenant to
        Landlord hereunder shall abate during such limited period in proportion
        to the portion of the Premises that is rendered untenantable and
        unusable as a result of such condemnation or other taking. Landlord
        shall be entitled to receive the entire award made in connection with
        any such temporary condemnation or other taking. Tenant shall have the
        right to claim and recover from the condemnor, but not from Landlord,
        such compensation as may be separately awarded or recoverable by Tenant
        in Tenant's own right on account of damages to Tenant's business by
        reason of the condemnation and for or on account of any cost or loss to
        which Tenant might be put in removing Tenant's merchandise, furniture
        and other personal property, fixtures and equipment or for the
        interruption of or damage to Tenant's business.

E.      Transfer of Landlord's Interest to Condemnor. Landlord may, without any
        obligation to Tenant, agree to sell and/or convey to the condemnor the
        Premises, the Building, the Project or any portion thereof, sought by
        the condemnor, free from this Lease and the rights of Tenant hereunder,
        without first requiring that any action or proceeding be instituted or,
        if instituted, pursued to a judgment.

SECTION 20.  DEFAULT

A.      Tenant's Default. The failure by Tenant to perform any one or more of
        the following obligations shall constitute a default hereunder by
        Tenant:

        (1)     If Tenant abandons all or a substantial portion of the Premises;

        (2)     If Tenant fails to pay any rent or other charges required to be
                paid by Tenant under this Lease and such failure continues for
                five (5) days after such payment is due and payable; provided,
                however, that the obligation of Tenant to pay a late charge or
                interest pursuant to this Lease below shall commence as of the
                due date of the rent or such other monetary obligation and not
                on the expiration of such five (5) day grace period;

        (3)     If Tenant involuntarily transfers Tenant's interest in this
                Lease or voluntarily transfers (attempted or actual) its
                interest in this Lease, without Landlord's prior written
                consent;

        (4)     If Tenant files a voluntary petition for relief or if a petition
                against Tenant in a proceeding under the Federal Bankruptcy Laws
                or other insolvency laws is filed and not withdrawn or dismissed
                within forty-five (45) days thereafter, or if under the
                provisions of any law providing for reorganization or winding up
                of corporations, any court of competent jurisdiction assumes
                jurisdiction, custody or control of Tenant or any substantial
                part of the Premises or any of Tenant's



                                       27
   28

                personal property located at the Premises and such jurisdiction,
                custody or control remains in force unrelinquished, unstayed or
                unterminated for a period of forty-five (45) days;

        (5)     If in any proceeding or action in which Tenant is a party, a
                trustee, receiver, agent or custodian is appointed to take
                charge of the Premises or any of Tenant's personal property
                located at the Premises (or has the authority to do so) for the
                purpose of enforcing a lien against the Premises or Tenant's
                personal property;

        (6)     If Tenant shall make any general assignment for the benefit of
                creditors or convene a meeting of its creditors or any class
                thereof for the purpose of effecting a moratorium upon or
                composition of its debts, or any class thereof;

        (7)     If Tenant fails to discharge any lien placed upon the Premises,
                the Building or the Project by Tenant or any person claiming
                under, by or through Tenant within ten (10) days of the
                imposition of such lien;

        (8)     If Tenant fails to promptly and fully perform any other
                covenant, condition or agreement contained in this Lease (other
                than subparagraphs (1) through (7) above) and such failure
                continues for ten (10) days after written notice thereof from
                Landlord to Tenant, or if such failure cannot be completely
                cured within such ten (10) day period, then if Tenant fails to
                commence such cure within such ten (10) day period and
                thereafter proceed to completely cure such failure within thirty
                (30) days after such written notice; or

        (9)     If Tenant is a partnership or consists of more than one (1)
                person or entity, if any partner of the partnership or other
                person or entity is involved in any of the acts or events
                described in subparagraphs (1) through (8) above.

B.      Remedies. Any notice given by Landlord pursuant to Section 20(A) above
        may be the notice required or permitted pursuant to Section 1161 et seq.
        of the California Code of Civil Procedure or successor statutes, and the
        provisions of this Lease shall not require the giving of a notice in
        addition to such statutory notice to terminate this Lease and Tenant's
        right to possession of the Premises. The periods specified in Section
        20(A) within which Tenant is permitted to cure any default following
        notice from Landlord shall run concurrently with any cure period
        provided by applicable laws. Upon the occurrence of a default by Tenant
        that is not cured by Tenant within any applicable grace period specified
        above, Landlord shall have the following rights and remedies in addition
        to all other rights and remedies available to Landlord at law or in
        equity, which shall be cumulative and non-exclusive:

        (1)     Without further notice or demand of any kind to Tenant or any
                other person, the right to declare this Lease and the term of
                this Lease terminated; re-enter the Premises and the
                improvements located thereon, with or without process of law; to
                eject all parties in possession thereof therefrom; repossess and
                enjoy the Premises together with all said improvements; and to
                recover from Tenant all of



                                       28
   29

                the following:

                (a)     The worth at the time of award of the unpaid rent which
                        had been earned at the time of termination; plus

                (b)     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 rental loss that Tenant proves could have been
                        reasonably avoided; plus

                (c)     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 rental loss that
                        Tenant proves could be reasonably avoided; plus

                (d)     Any other amount necessary to compensate Landlord for
                        all the detriment proximately caused by Tenant's failure
                        to perform its obligations under this Lease or which in
                        the ordinary course of things would be likely to result
                        therefrom, including, but not limited to, any attorneys'
                        fees, broker's commissions or finder's fees (not only in
                        connection with the reletting of the Premises, but also
                        that portion of any leasing commission paid by Landlord
                        in connection with this Lease which is applicable to
                        that portion of the Term which is unexpired as of the
                        date on which this Lease is terminated); the then
                        unamortized cost of any tenant improvements constructed
                        for or on behalf of Tenant by or at the expense of
                        Landlord or of any moving allowance or other concession
                        made available to Tenant and/or paid by Landlord
                        pursuant to this Lease; any costs for repairs, clean-up,
                        refurbishing, removal (including the repair of any
                        damage caused by such removal) and storage (or disposal)
                        of Tenant's personal property, equipment, fixtures, and
                        anything else that Tenant is required (under this Lease)
                        to remove but does not remove; any costs for
                        alterations, additions and renovations; and any other
                        costs and expenses, including reasonable attorneys' fees
                        and costs, incurred by Landlord in regaining possession
                        of and reletting (or attempting to relet) the Premises.

        (2)     The right to continue this Lease in effect and to enforce all of
                Landlord's rights and remedies under this Lease, including the
                right to recover rent and any other additional monetary charges
                as they become due, for as long as Landlord does not terminate
                Tenant's right to possession. Acts of maintenance or
                preservation, efforts to relet the Premises, the appointment of
                a receiver upon Landlord's initiative to protect its interest
                under this Lease or Landlord's withholding of consent to an
                Assignment or Subletting pursuant to the terms and conditions of
                Section 16 above shall not constitute a termination of Tenant's
                right to possession.

        (3)     The foregoing provisions of clause (2) shall apply even though
                Tenant has breached the Lease and abandoned the Premises, in
                which case Landlord shall have the right to re-enter the
                Premises with or without process of law to eject



                                       29
   30

                therefrom all parties in possession thereof, and, without
                terminating this Lease, at any time and from time to time, but
                without obligation to do so, to relet the Premises and the
                improvements located therein or any part or parts of any thereof
                for the account of Tenant, or otherwise, on such conditions as
                Landlord in its discretion may deem proper, with the right to
                make alterations and repairs to the Premises in connection
                therewith, and to receive and collect the rents therefor, and
                apply the same (a) first to the payment of such costs and
                expenses as Landlord may have paid, assumed or incurred: (I) in
                recovering possession of the Premises and said improvements,
                including attorneys' fees, and costs; (II) on expenses for
                placing the Premises and said improvements in good order and
                condition, for decorating and preparing the Premises for
                reletting; (III) for making any alterations, repairs, changes or
                additions to the Premises that may be necessary or convenient;
                and (IV) for all other costs and expenses, including leasing and
                subleasing commissions, and charges paid, assumed or incurred by
                Landlord in or upon reletting the Premises and said
                improvements, or in fulfillment of the covenants of Tenant under
                this Lease; (b) then to the payment of Monthly Rental and other
                monetary obligations due and unpaid hereunder; and (c) any
                balance shall be held by Landlord and applied in payment of
                future amounts as the same may become due and payable hereunder.
                Any such reletting may be for the remainder of the term of this
                Lease or for a longer or shorter period. Landlord may execute
                any lease or sublease made pursuant to the terms of this clause
                (3) either in its own name or in the name of Tenant as its
                agent, as Landlord may see fit. The tenant(s) or subtenant(s)
                thereunder shall be under no obligation whatsoever with regard
                to the application by Landlord of any rent collected by Landlord
                from such tenant or subtenant to any and all sums due and owing
                or which may become due and owing under the provisions of this
                Lease, nor shall Tenant have any right or authority whatever to
                collect any rent whatever from such tenant(s) or subtenant(s).
                If Tenant has been credited with any rent received by such
                reletting and such rent shall not be promptly paid to Landlord
                by the tenant(s) or subtenant(s), or if such rentals received
                from reletting during any month are less than those to be paid
                during that month by Tenant hereunder, Tenant shall pay any such
                deficiency to Landlord. Such deficiency shall be calculated and
                paid monthly. Tenant shall also pay to Landlord as soon as
                ascertained, any costs and expenses incurred by Landlord in such
                reletting or in making such alterations and repairs not covered
                by the rentals received from such reletting. For all purposes
                set forth in this clause (3), Landlord is hereby irrevocably
                appointed as agent for Tenant. No taking of possession of the
                Premises by Landlord shall be construed as Landlord's acceptance
                of a surrender of the Premises by Tenant or an election on
                Landlord's part to terminate this Lease unless written notice of
                such intention is given to Tenant. Notwithstanding any such
                subletting without termination, Landlord may at any time
                thereafter elect to terminate this Lease for such previous
                breach. Election by Landlord to proceed pursuant to this clause
                (3) shall be made upon written notice to Tenant and shall be
                deemed an election of the remedy described in California Civil
                Code Section 1951.4 (providing that a lessor of real property
                may continue a lease in effect after a lessee's breach or
                abandonment and recover rent as it becomes due, if the lessee



                                       30
   31

                has the right to sublet or assign, subject only to reasonable
                limitations). If Landlord elects to pursue such remedy, unless
                Landlord relets the Premises, Tenant shall have the right to
                sublet the Premises and to assign its interest in this Lease,
                subject to all of the standards and conditions set forth in
                Section 16. Landlord may elect to terminate the prosecution of
                such remedy at any time by written notice to Tenant, and the
                right of Tenant to sublet or assign shall terminate upon receipt
                by Tenant of such notice.

        (4)     The right to have a receiver appointed for Tenant, upon
                application by Landlord, to take possession of the Premises and
                to apply any rental collected from the Premises and to exercise
                all other rights and remedies granted to Landlord pursuant to
                this subsection.

C.      Relief From Forfeiture. Tenant hereby waives all rights under California
        Code of Civil Procedure Section 1179 and California Civil Code Section
        3275 providing for relief from forfeiture, and any other right now or
        hereafter existing to redeem the Premises or reinstate this Lease after
        termination pursuant to this Section 20 or by order or judgment of any
        court or by any legal process.

SECTION 21.  LATE PAYMENTS/INTEREST AND LATE CHARGES

A.      [Intentionally Omitted]

B.      Interest. Any amount due from Tenant to Landlord which is not paid when
        due shall bear interest at the rate of one percent (1%) per month or, if
        less, the maximum rate permitted by law from the date such payment is
        due until paid, except that amounts spent by Landlord on behalf of
        Tenant shall bear interest at such rate from the date of disbursement by
        Landlord which Tenant agrees is to compensate Landlord for Tenant's use
        of Landlord's money after it is due. Payment of such interest shall not
        excuse or cure any default by Tenant pursuant to this Lease. Such rate
        shall remain in effect after the occurrence of any breach or default
        hereunder by Tenant to and until payment of the entire amount due.

C.      Late Charges. TENANT HEREBY ACKNOWLEDGES THAT IN ADDITION TO LOST
        INTEREST, THE LATE PAYMENT BY TENANT TO LANDLORD OF RENT OR ANY OTHER
        SUMS DUE HEREUNDER WILL CAUSE LANDLORD TO INCUR OTHER COSTS NOT
        CONTEMPLATED IN THIS LEASE, THE EXACT AMOUNT OF WHICH WILL BE EXTREMELY
        DIFFICULT AND IMPRACTICABLE TO ASCERTAIN. SUCH OTHER COSTS INCLUDE, BUT
        ARE NOT LIMITED TO, PROCESSING, ADMINISTRATIVE AND ACCOUNTING COSTS, AND
        LATE CHARGES WHICH MAY BE IMPOSED UPON LANDLORD BY THE TERMS OF ANY
        ENCUMBRANCE COVERING THE PREMISES. ACCORDINGLY, IF ANY INSTALLMENT OF
        RENT OR ANY ADDITIONAL RENT OR OTHER SUM DUE FROM TENANT SHALL NOT BE
        RECEIVED BY LANDLORD WHEN SUCH AMOUNT SHALL BE DUE (WITHOUT REGARD TO
        ANY GRACE PERIOD GRANTED IN THIS LEASE), TENANT SHALL PAY TO LANDLORD AS



                                       31
   32

        ADDITIONAL RENT HEREUNDER A LATE CHARGE EQUAL TO THE LESSER OF FIVE
        PERCENT (5%) OF SUCH OVERDUE AMOUNT OR $1,500.00. THE PARTIES HEREBY
        AGREE THAT (i) SUCH LATE CHARGE REPRESENTS A FAIR AND REASONABLE
        ESTIMATE OF THE COSTS LANDLORD WILL INCUR IN PROCESSING SUCH DELINQUENT
        PAYMENT BY TENANT, (ii) SUCH LATE CHARGE SHALL BE PAID TO LANDLORD AS
        LIQUIDATED DAMAGES FOR EACH DELINQUENT PAYMENT, AND (iii) THE PAYMENT OF
        THE LATE CHARGE IS TO COMPENSATE LANDLORD FOR THE ADDITIONAL
        ADMINISTRATIVE EXPENSE INCURRED BY LANDLORD IN HANDLING AND PROCESSING
        DELINQUENT PAYMENTS.

        -------------------         -----------------
        Landlord's Initials         Tenant's Initials

D.      No Waiver. Neither assessment nor acceptance of partial payments,
        interest or late charges by Landlord shall constitute a waiver of
        Tenant's default with respect to such overdue amount, nor prevent
        Landlord from exercising any of its other rights and remedies under this
        Lease. Nothing contained in this Section shall be deemed to condone,
        authorize, sanction or grant to Tenant an option for the late payment of
        rent, additional rent or other sums due hereunder, and Tenant shall be
        deemed in default with regard to any such payments should the same not
        be made by the date on which they are due.

SECTION 22. [INTENTIONALLY OMITTED].

SECTION 23.  HOLDING OVER

Any holding over by Tenant in the possession of the Premises, or any portion
thereof, after the expiration or earlier termination of the Term, with the prior
written consent of Landlord, shall be construed to be a tenancy from month to
month at one hundred fifty percent (150%) of the Monthly Rental herein specified
for the last month in the Term (prorated on a monthly basis) unless Landlord
shall specify a lesser amount for rent in its sole discretion, and shall
otherwise be on the terms and conditions herein specified as far as applicable.
Any holding over without Landlord's consent shall constitute a default by Tenant
and shall entitle Landlord to pursue all remedies provided in this Lease and
Tenant shall be liable for any and all direct or consequential damages or losses
of Landlord resulting from Tenant's holding over without Landlord's consent.

SECTION 24.  ATTORNEYS' FEES

Tenant shall pay to Landlord all amounts for costs and expenses, including, but
not limited to, reasonable attorneys' fees and amounts paid to any collection
agency, incurred by Landlord in connection with any breach or default by Tenant
under this Lease or incurred in order to enforce or interpret the terms or
provisions of this Lease. Tenant shall also pay to Landlord all such amounts,
including attorneys' fees, incurred by Landlord in responding to any request by
Tenant (a) to amend or modify this Lease or (b) to prepare any statement or
document in connection with this Lease, including without limitation estoppel
certificates or subordination agreements or



                                       32
   33

the like. Such amounts shall be payable upon demand. In addition, if any action
shall be instituted by either Landlord or Tenant for the enforcement or
interpretation of any of its rights or remedies in or under this Lease, the
prevailing party shall be entitled to recover from the losing party all costs
incurred by the prevailing party in said action and any appeal therefrom,
including reasonable attorneys' fees and court costs to be fixed by the court
therein. In the event Landlord is made a party to any litigation between Tenant
and any third party, then Tenant shall pay all costs and attorneys' fees
incurred by or imposed upon Landlord in connection with such litigation;
provided, however, if Landlord is ultimately held to be liable, then Landlord
shall reimburse Tenant for the cost of any attorneys' fees paid by Tenant on
behalf of Landlord.

SECTION 25.  MORTGAGE PROTECTION/SUBORDINATION

A.      Subordination. The rights of Tenant under this Lease are and shall be,
        at the option of Landlord, either subordinate or superior to any
        mortgage or deed of trust (including a consolidated mortgage or deed of
        trust) constituting a lien on the Premises, Building or Project, or
        Landlord's interest therein or any part thereof, whether such mortgage
        or deed of trust has heretofore been, or may hereafter be, placed upon
        the Premises by Landlord, and to any ground or master lease if
        Landlord's title to the Premises or any part thereof is or shall become
        a leasehold interest. To further assure the foregoing subordination or
        superiority, Tenant shall, upon Landlord's request, together with the
        request of any mortgagee under a mortgage or beneficiary under a deed of
        trust or ground or master lessor, execute any instrument (including
        without limitation an amendment to this Lease that does not materially
        and adversely affect Tenant's rights or materially increase Tenant's
        obligations under this Lease) or instruments intended to subordinate
        this Lease, or at the option of Landlord, to make it superior to any
        mortgage, deed of trust, or ground or master lease. Notwithstanding any
        such subordination, Tenant's right to occupy the Premises pursuant to
        this Lease shall remain in effect for the full Term as long as Tenant is
        not in default hereunder.

B.      Attornment. Notwithstanding Section 25(A) above, Tenant agrees (1) to
        attorn to any mortgagee of a mortgage or beneficiary of a deed of trust
        encumbering the Premises and to any party acquiring title to the
        Premises by judicial foreclosure, trustee's sale, or deed in lieu of
        foreclosure, and to any ground or master lessor, as the successor to
        Landlord hereunder, (2) to execute any attornment agreement reasonably
        requested by a mortgagee, beneficiary, ground or master lessor, or party
        so acquiring title to the Premises, and (3) that this Lease, subject to
        the rights under any outstanding non-disturbance agreement, at the
        option of such mortgagee, beneficiary, or ground or master lessor, or
        other party, shall remain in force notwithstanding any such judicial
        foreclosure, trustee's sale, deed in lieu of foreclosure, or merger of
        titles. Notwithstanding the foregoing, neither a mortgagee of a mortgage
        or beneficiary of a deed of trust encumbering the Premises, any party
        acquiring title to the Premises by judicial foreclosure, trustee sale,
        or deed in lieu of foreclosure, or any ground lessor or master lessor,
        as the successor to Landlord hereunder, shall be liable or responsible
        for any breach of a covenant contained in this Lease that occurred
        before such party acquired its interest in the Premises or for any
        continuing breach thereof until after the successor Landlord has
        received the notice and right to cure as provided herein, and no such
        party



                                       33
   34

        shall be liable or responsible for any security deposits held by
        Landlord hereunder which have not been transferred or actually received
        by such party, and such party shall not be bound by any payment of rent
        or additional rent for more than two (2) months in advance.

C.      Amendment. If any lending institution with which Landlord has negotiated
        or may negotiate for financing for the Building or Project requires any
        changes to this Lease, Tenant shall promptly execute and deliver an
        amendment to this Lease prepared by Landlord and embodying such changes,
        so long as such changes do not materially and adversely affect Tenant's
        rights or materially increase Tenant's obligations hereunder. In the
        event that Tenant shall fail to execute and deliver such amendment
        within twenty (20) days after receipt thereof by Tenant, such failure
        shall constitute a default hereunder by Tenant and shall entitle
        Landlord to all remedies available to a landlord against a defaulting
        tenant pursuant to a written lease, including but not limited to those
        remedies set forth in Section 20.

SECTION 26.  ESTOPPEL CERTIFICATE/FINANCIAL STATEMENTS

A.      Estoppel Certificate. Tenant, at any time and from time to time upon not
        less than ten (10) days' prior written notice from Landlord, agrees to
        execute and deliver to Landlord a statement in the form provided by
        Landlord (1) certifying that this Lease is unmodified and in full force
        and effect, or, if modified, stating the nature of such modification and
        certifying that this Lease, as so modified, is in full force and effect
        and the date to which the rent and other charges are paid in advance, if
        any; (2) acknowledging that there are not, to Tenant's knowledge, any
        uncured defaults on the part of Landlord hereunder, or specifying such
        defaults if they are claimed evidencing the status of this Lease; (3)
        acknowledging the amount of the Security Deposit held by Landlord; and
        (4) containing such other information regarding this Lease or Tenant as
        Landlord reasonably requests. Tenant's failure to deliver an estoppel
        certificate within such time shall be conclusive upon Tenant that (i)
        this Lease is in full force and effect without modification except as
        may be represented by Landlord, (ii) to Tenant's knowledge there are no
        uncured defaults in Landlord's performance, (iii) no rent has been paid
        in advance except as set forth in this Lease, and (iv) such other
        information regarding this Lease and Tenant set forth therein by
        Landlord is true and complete.

B.      Furnishing of Financial Statements. Landlord has reviewed the financial

        maintained an automobile parking area and to maintain and operate, or
        cause to be maintained and operated, said automobile parking area during
        the Term of this Lease for the benefit and non-exclusive use by Tenant
        and the customers, service suppliers, other invitees and employees of
        Tenant. Whenever the words "automobile parking area" or "parking area"
        are used in this Lease, it is intended that the same shall include,
        whether in a surface parking area or a parking structure, the automobile
        parking stalls, driveways, loading docks, truck areas, service drives,
        entrances and exits and sidewalks, landscaped areas, pedestrian
        passageways in conjunction therewith and other areas designated for
        parking. Landlord shall keep said automobile parking area in a neat,
        clean and orderly condition, lighted and landscaped, and shall repair
        any damage to the facilities thereof. Nothing contained herein shall be
        deemed to impose liability upon Landlord for personal injury or theft,
        for damage to any motor vehicle, or for loss of property from within any
        motor vehicle, which is suffered by Tenant or any of its employees,
        customers, service suppliers or other invitees in connection with their
        use of said automobile parking area. Landlord shall also have the right
        to establish such reasonable rules and regulations as may be deemed
        desirable, at Landlord's sole discretion, for the proper and efficient
        operation and maintenance of said automobile parking area. Such rules
        and regulations may include, without limitation, (i) restrictions on the
        hours during which the automobile parking area shall be open for use and
        (ii) the establishment on a non-discriminatory basis of charges for
        parking therein (on either a reserved or unreserved basis, at Landlord's
        sole discretion) by tenants of the Building as well as by their
        employees, customers and service suppliers.

B.      Tenant's Rights and Obligations. Tenant shall be entitled to use the
        number of vehicle parking spaces allocated to Tenant in Section 1(P)
        without paying any additional rent therefor. Tenant and its employees
        shall park their vehicles only in those portions of the Common Areas or
        other locations designated and provided for that purpose by Landlord.
        Tenant's parking shall not be reserved and shall be limited to vehicles
        no longer than standard size automobiles or pickup or sport utility
        vehicles. Tenant shall not cause large trucks or other large vehicles to
        be parked within the Project or on the adjacent public streets except in
        accordance with the Rules. Vehicles shall be parked only in striped
        parking spaces and not in driveways or other locations not specifically
        designated for parking. Handicapped spaces shall only be used by those
        legally permitted to use them. Tenant shall not use or permit the use of
        loading areas, any spaces which have been specifically assigned by
        Landlord to employees of Landlord or other tenants or for such other
        uses as visitor parking or which have been designated by governmental
        entities as being restricted to certain uses. Tenant shall not permit or
        allow any vehicles that belong to or are controlled by Tenant or
        Tenant's employees, suppliers, shippers, customers, or invitees to be
        loaded, unloaded, or parked in areas other than those designated by



                                       35
   36

        Landlord for such activities. The parking area shall not be used to
        provide car wash, oil changes, detailing, automotive repair or other
        services unless otherwise approved or furnished by Landlord. Tenant
        shall furnish Landlord with its and its employees' license plate numbers
        within fifteen (15) days after taking possession of the Premises, and
        Tenant shall thereafter notify Landlord of any changes within five (5)
        days after such change occurs. If Tenant or its employees fail to park
        their cars in designated parking areas, then Landlord may charge Tenant
        Fifteen Dollars ($15.00) per day for each day or partial day that any
        such car is parked in any area other than those designated. Overnight
        and weekend parking shall not be permitted unless Tenant has provided
        Landlord with advance written notice thereof. If Tenant permits or
        allows any of the prohibited activities described herein, Landlord shall
        have the right, without notice, in addition to any other rights it may
        have, to remove or tow away the vehicle. If Landlord shall tow any
        vehicles of Tenant or its employees, suppliers, shippers, customers, or
        invitees, Tenant shall pay to Landlord the costs and expenses incurred
        by Landlord in connection therewith, within ten (10) days after Landlord
        sends Tenant an invoice therefor.

C.      Control of Parking Area. Landlord shall at all times during the Term
        hereof have the sole and exclusive control of the automobile parking
        area, and may at any time during the Term hereof exclude and restrain
        any person from use or occupancy thereof; excepting, however, Tenant and
        employees, customers, service suppliers and other invitees of Tenant and
        of other tenants in the Building who make use of said area in accordance
        with any rules and regulations established by Landlord from time to time
        with respect thereto. The rights of Tenant and its employees, customers,
        service suppliers and invitees referred to in this Section 27 shall at
        all times be subject to (i) the rights of Landlord and other tenants in
        the Building and their customers, employees, licensees, invitees,
        successors and assigns to use the same in common with Tenant and its
        employees, customers, service suppliers and invitees, (ii) the
        availability of parking spaces in said automobile parking area, and
        (iii) Landlord's right to assign reserved parking spaces and to change
        the location of any assigned reserved parking spaces in such instances
        as shall be determined at Landlord's sole discretion. Notwithstanding
        Landlord's exclusive control and obligations to provide a parking area,
        Landlord is not responsible or liable for any damage to any automobiles
        or persons in the parking area.

SECTION 28.  SIGNS; NAME OF BUILDING

A.      Signs. Landlord shall enter Tenant's name in the Building directory
        located in the main lobby of the Building and in the elevator lobby of
        the floor on which the Premises is located. Tenant shall not have the
        right to place, construct, or maintain on or about the Premises,
        Building or Project, or in any interior portions of the Premises that
        may be visible from the exterior of the Building or Common Areas, any
        signs, names, insignia, trademark, advertising placard, descriptive
        material or any other similar item ("Sign") without Landlord's prior
        written consent, which consent may be withheld in Landlord's sole
        discretion; provided, however, any Signs are further subject to approval
        of any applicable governmental authority and/or compliance with
        applicable governmental requirements and covenants, conditions and
        restrictions applicable to the Building or the Project. In the event
        Landlord consents to Tenant placing a Sign on or about the



                                       36
   37

        Premises, Building or Project, any such Sign shall be subject to
        Landlord's approval of the color, size, style and location of such Sign,
        and shall conform to any current or future Sign criteria established by
        Landlord for the Building or Project. If Landlord enacts a Sign criteria
        or revises an existing Sign criteria, after Tenant has erected a Sign to
        which Landlord has granted its consent, if Landlord so elects, Tenant
        agrees, at Landlord's expense, subject to Landlord's prior approval of
        the cost thereof, to make the necessary changes to its Sign in order to
        conform the Sign to Landlord's Sign criteria, as enacted or revised,
        provided that such changes shall be limited to the color, size, style
        and location of Tenant's Sign and that Tenant shall not be required to
        change the content of its Sign. In the event Landlord consents to
        Tenant's placement of a Sign on the Building, Tenant shall, at its sole
        cost, remove such Sign from the Building at the end of the Term, restore
        the Building to the same condition as before the installation of the
        Sign, ordinary wear and tear excepted and remove any discoloration of
        the Building caused by the presence of such sign.

B.      Building Identification. Landlord reserves the right at any time it
        deems necessary or appropriate to (1) place Signs at any location on the
        Building and Project as it deems necessary and (2) change the name,
        address or designation of the Building and Project.

SECTION 29.  QUIET ENJOYMENT

Upon payment by Tenant of the rents herein provided, and upon the observance and
performance of all the covenants, terms and conditions on Tenant's part to be
observed and performed, Tenant shall peaceably and quietly hold and enjoy the
Premises for the Term without hindrance or interruption by Landlord or any other
person or persons lawfully or equitably claiming by, through or under Landlord,
subject, nevertheless, to the terms and conditions of this Lease, and any
mortgage and/or deed of trust to which this Lease is subordinate.

SECTION 30.  ADDITIONAL FACILITIES AVAILABLE TO TENANT

A.      Conference Rooms. Tenant shall have the right to reserve the use of (1)
        the Bay Conference Room located on the second floor of the Building
        without paying any additional rent therefor, (2) the Pacific Conference
        Room located on the second floor of the Building free of charge once
        each calendar quarter and at other times at a fee of $100.00 per day or
        partial day (plus a set-up fee based on Landlord's standard hourly rates
        to be determined from time to time) and (3) any other conference room
        located on the second floor of the Building at Landlord's standard
        hourly rates to be determined from time to time. Tenant shall pay
        Landlord for any audio/visual, video conferencing or other equipment
        available in any such conference room a fee to be determined by Landlord
        from time to time; provided however, Tenant acknowledges that Landlord
        does not guarantee that any such equipment will be available or in
        working order at any time. Landlord shall notify Tenant of any
        discretionary fees described above at such time as Tenant requests use
        of any such conference room or equipment. Such use of the conference
        rooms on the second floor of the Building shall be on a non-exclusive
        basis during normal business hours (as designated by Landlord from time
        to time) and shall in all other respects be subject to the same
        obligations set forth in this Lease regarding



                                       37
   38

        Tenant's use of the Common Areas. If Tenant desires to reserve a
        conference room, Tenant shall notify Landlord on Landlord's standard
        reservation form or in another manner acceptable to Landlord at least
        ten (10) business days before the desired date of use. Landlord shall
        notify Tenant within five (5) business days after receipt of Tenant's
        request whether the requested conference room is available for Tenant's
        use in accordance with the rules of Landlord from time to time in
        effect, which may include rules to ensure that Tenant's use of
        conference facilities is not disproportionate to the Rental Area of the
        Premises. If not, Tenant may request the use of another conference room,
        however Tenant agrees that Landlord shall have no obligation to respond
        to such request within less than five (5) business days after receipt of
        Tenant's request. Tenant hereby waives any claims it may have against
        Landlord due to the unavailablility of a conference room at any time,
        regardless whether Landlord has notified Tenant that a particular
        conference room is available for Tenant's use, except for claims due to
        Landlord's willful misconduct. Landlord shall not be required to make
        conference facilities available to Tenant if Landlord elects, in its
        discretion, to cease to maintain and operate shared conference
        facilities in the Building.

B.      Fitness Center. Tenant shall be entitled to use the number of Fitness
        Center Memberships allocated to Tenant in Section 1(Q) without paying
        any additional rent therefor. Such use of the Fitness Center at the
        Building shall be on a non-exclusive basis during the standard hours of
        operation of the Fitness Center (as designated by Landlord from time to
        time) and shall in all other respects be subject to the same obligations
        set forth in this Lease regarding Tenant's use of the Common Areas.
        Tenant shall have the right to purchase additional Fitness Center
        Memberships at $50 per Membership per month. Such amounts shall be
        payable to Landlord as additional rent and shall be subject to increase
        on written notice from Landlord. Memberships may only be used by
        employees of Tenant and not spouses or friends of Tenant's employees or
        customers, consultants, vendors or agents of Tenant. Tenant shall assign
        Memberships to specific employees and shall arrange for the security
        badges of such employees to allow them access to the Fitness Center.
        Tenant shall notify Landlord of the names of such employees at such time
        or times as Tenant allocates Memberships to its employees. Tenant shall
        ensure that the assigned employees do not allow other individuals to use
        the assigned Memberships. Memberships shall be granted by Landlord only
        to Tenant; Landlord shall not have any obligation to grant Memberships
        directly to employees of Tenant. Prior to using the Fitness Center for
        the first time, each employee of Tenant shall sign a written waiver on
        Landlord's standard form releasing Landlord from all liability for
        personal injury or theft or for loss of property from within the Fitness
        Center. Nothing contained herein shall be deemed to impose, and Tenant
        hereby waives on behalf of itself and all users of the Fitness Center
        Memberships (authorized or unauthorized, paid or unpaid), liability
        against Landlord for personal injury or theft or for loss of property
        from within the Fitness Center, which is suffered by Tenant or any of
        its employees or other parties. Tenant further agrees to indemnify,
        defend and hold Landlord and its officers, directors, partners, agents
        and employees (collectively, "Indemnitees") entirely harmless from and
        against all liabilities, losses, demands, actions, expenses or claims,
        including reasonable attorneys' fees and court costs, for injury to or
        death of any person or for damages to any property or for violation of
        law arising out of or in any manner connected with the use, occupancy or



                                       38
   39

        enjoyment of the Fitness Center by Tenant or and users of the Fitness
        Center Memberships (authorized or unauthorized, paid or unpaid).
        Landlord shall not be required to make the Fitness Center available as
        provided above if Landlord elects, in its discretion, to discontinue
        operation of the Fitness Center.

C.      Fees. All amounts payable to Landlord pursuant to this Section 30 shall
        be deemed additional rent. All fees described herein shall be payable by
        Tenant regardless whether Tenant or its employees use the conference
        room(s) that have been reserved or the paid Fitness Center Memberships,
        as applicable.

SECTION 31.  NOTICES

Any notice, demand, approval, consent, bill, statement or other communication
("Notice") required or desired to be given under this Lease shall be in writing,
shall be directed to Tenant at Tenant's Address for Notice or to Landlord at
Landlord's Address for Notice and shall be personally served or given by
pre-paid certified U.S. Mail or "overnight" delivery service. In the case of
personal delivery, any Notice shall be deemed to have been given when delivered;
in the case of service by certified mail, any Notice shall be deemed delivered
of the date of receipt, refusal or non-delivery indicated on the return receipt;
and in the case of overnight delivery service, any Notice shall be deemed given
when delivered as evidenced by a receipt. If more than one Tenant is named under
this Lease, service of any Notice upon any one of said Tenants shall be deemed
as service upon all of such Tenants. The parties hereto and their respective
heirs, successors, legal representatives, and assigns may from time to time
change their respective addresses for Notice by giving at least fifteen (15)
days' written notice to the other party, delivered in compliance with this
Section.

SECTION 32.  NOTICE AND CURE TO LANDLORD AND MORTGAGEE

On any act or omission by Landlord which might give, or which Tenant claims or
intends to claim gives, Tenant the right to damages from Landlord or the right
to terminate this Lease by reason of a constructive or actual eviction from all
or part of the Premises, or otherwise, Tenant shall not sue for damages or
attempt to terminate this Lease until it has given written notice of the act or
omission to Landlord and to the holder(s) of the indebtedness or other
obligations secured by any mortgage or deed of trust affecting the Premises as
identified by Landlord, and a reasonable period of time for remedying the act or
omission has elapsed following the giving of the notice, during which time
Landlord and the lienholder(s), or either of them, their agents or employees,
may enter upon the Premises and do therein whatever is necessary to remedy the
act or omission. During the period after the giving of notice and during the
remedying of the act or omission, the Monthly Rental payable by Tenant shall not
be abated and apportioned except to the extent that the Premises are
untenantable.

SECTION 33.  GENERAL

A.      Paragraph Headings. The paragraph headings used in this Lease are for
        the purposes of convenience only. They shall not be construed to limit
        or to extend the meaning of any part of this Lease.

B.      Incorporation of Prior Agreements; Amendments. This Lease contains all
        agreements of Landlord and Tenant with respect to any matter mentioned,
        or dealt with, herein. No prior agreement or understanding pertaining to
        any such matter shall be binding upon Landlord. Any amendments to or
        modifications of this Lease shall be in writing, signed by the parties
        hereto, and neither Landlord nor Tenant shall be liable for any oral or
        implied agreements. LANDLORD HAS NOT MADE, AND TENANT MAY NOT RELY ON,
        ANY REPRESENTATIONS OR WARRANTIES, EXPRESSED OR IMPLIED, WITH REGARD TO
        THE PROJECT, THE BUILDING, THE PREMISES OR OTHERWISE OR THE SUITABILITY
        THEREOF FOR TENANT'S BUSINESS, EXCEPT AS EXPRESSLY STATED IN THIS LEASE.
        IN PARTICULAR, LANDLORD HAS NOT AUTHORIZED ANY AGENT OR BROKER TO MAKE A
        REPRESENTATION OR WARRANTY INCONSISTENT WITH THE TERMS OF THIS LEASE AND
        TENANT MAY NOT RELY ON ANY SUCH INCONSISTENT REPRESENTATION OR WARRANTY.

C.      Waiver. Any waiver by Landlord of any breach of any term, covenant, or
        condition contained in this Lease shall not be deemed to be a waiver of
        such term, covenant, or condition or of any subsequent breach of the
        same or of any other term, covenant, or condition contained in this
        Lease. Landlord's consent to, or approval of, any act shall not be
        deemed to render unnecessary the obtaining of Landlord's consent to, or
        approval of, any subsequent act by Tenant. The acceptance of rent or
        other sums payable hereunder by Landlord shall not be a waiver of any
        preceding breach by Tenant of any provision hereof, other than failure
        of Tenant to pay the particular rent or other sum so accepted,
        regardless of Landlord's knowledge of such preceding breach at the time
        of acceptance of such rent, or sum equivalent to rent.

D.      Short Form or Memorandum of Lease. Tenant agrees, at the request of
        Landlord, to execute, deliver, and acknowledge a short form or
        memorandum of this Lease satisfactory to counsel for Landlord, and
        Landlord may, in its sole discretion, record such short form or
        memorandum in the county where the Premises are located. Tenant shall
        not record this Lease, or a short form or memorandum of this Lease,
        without Landlord's prior written consent.

E.      Time of Essence. Time is of the essence in the performance of each
        provision of this Lease.

F.      Examination of Lease. Submission of this instrument for examination or
        signature by Tenant does not constitute a reservation of or option for
        lease, and it is not effective as a lease or otherwise until execution
        by and delivery to both Landlord and Tenant.

G.      Severability. If any term or provision of this Lease or the application
        thereof to any person or circumstance shall, to any extent, be invalid
        or unenforceable, the remainder of this Lease, or the application of
        such term or provision to persons or circumstances other than those as
        to which it is held invalid or unenforceable, shall not be affected
        thereby, and each term and provision of this Lease shall be valid and be
        enforced to the fullest



                                       40
   41

        extent permitted by law.

H.      Surrender of Lease Not Merger. Neither the voluntary or other surrender
        of this Lease by Tenant nor the mutual cancellation thereof shall cause
        a merger of the titles of Landlord and Tenant, but such surrender or
        cancellation shall, at the option of Landlord, either terminate all or
        any existing subleases or operate as an assignment to Landlord of any
        such subleases. The delivery of keys to the Premises to Landlord or its
        agent shall not, of itself, constitute a surrender and termination of
        this Lease.

I.      Authority. If Tenant is a corporation, each individual executing this
        Lease on behalf of Tenant represents and warrants (1) that he or she is
        duly authorized to execute and deliver this Lease on behalf of Tenant in
        accordance with a duly adopted resolution of the Board of Directors of
        Tenant in accordance with the By-laws of Tenant and (2) that this Lease
        is binding upon and enforceable by Landlord against Tenant in accordance
        with its terms. If Tenant is a corporation, Tenant shall, concurrently
        with delivery of an executed Lease to Landlord, deliver to Landlord a
        certified copy of a resolution of its Board of Directors authorizing or
        ratifying the execution of this Lease. If Tenant is a partnership, joint
        venture, or other unincorporated association, each individual executing
        this Lease on behalf of Tenant warrants that this Lease is binding on
        Tenant and that each and both of the persons signing on behalf of Tenant
        were authorized to do so.

J.      Governing Law. This Lease and the rights and obligations of the parties
        hereto shall be interpreted, construed and enforced in accordance with
        the local laws of the State in which the Building is located.

K.      Force Majeure. If the performance by Landlord of any provision of this
        Lease is delayed or prevented by any act of God, strike, lockout,
        shortage of material or labor, restriction by any governmental
        authority, civil riot, flood, and any other cause not within the control
        of Landlord, then the period for Landlord's performance of the provision
        shall be automatically extended for the same time Landlord is so delayed
        or hindered.

L.      Use of Language. Words of gender used in this Lease include any other
        gender, and words in the singular include the plural, unless the context
        otherwise requires.

        inure to the benefit of and are binding on, the parties hereto and their
        respective successors in interest, assigns and legal representatives,
        except as otherwise herein expressly provided. All rights, privileges,
        immunities and duties of Landlord under this Lease, including without
        limitation, notices required or permitted to be delivered by Landlord to
        Tenant hereunder, may, at Landlord's option, be exercised or performed
        by Landlord's agent or attorney.

N.      No Reduction of Rental. Except as otherwise expressly and unequivocally
        provided in this Lease, Tenant shall not for any reason withhold or
        reduce the amounts payable by Tenant under this Lease, it being
        understood that the obligations of Landlord hereunder are independent of

        any portion thereof, and either party may disclose the terms hereof to

        financial statements or prepare its respective tax returns, to any
        prospective transferee of all or any portions of their respective
        interests hereunder (including a prospective sublessee or assignee of
        Tenant), to its respective real estate brokers, to any lender or
        prospective lender to such party, to any governmental entity, agency or
        person to whom disclosure is required by applicable law, regulation or
        duty of diligent inquiry and in connection with any action brought to
        enforce the terms of this Lease, on account of the breach or alleged
        breach hereof or to seek a judicial determination of the rights and
        obligations of the parties hereunder.
