2.3  Lease Commencement Date And Lease Term. The term of this Lease shall begin,
and the Lease Commencement Date shall be deemed to have occurred, on that date
which is six (6) months after Landlord's delivery to Tenant of the Building
Shell in accordance with Paragraph 2.4, which is anticipated to be that date set
forth in Article 1 (the "Lease Commencement Date"). The term of this Lease shall
in all events end on the Lease Expiration Date (as Set forth in Article 1). The
Lease Term shall be that period of time commencing on the Lease Commencement
Date and ending on the Lease Expiration Date (the "Lease Term"). In the event
that the Lease Commencement Date is on any date other than the date set forth in
Article 1 as the Lease Commencement Date, Landlord and Tenant agree to execute a
Lease Commencement Date Certificate in the form attached as Exhibit D, setting
forth the actual Lease Commencement Date as determined pursuant to this

Tenant with the Building Shell (as defined below) substantially complete on the
Effective Date of this Lease. Landlord shall complete the electrical service
identified as Item 4 on Schedule I to the Work Letter (which shall not be deemed
part of the Building Shell) within ninety (90) days after the Effective Date of
this Lease. Tenant's obligation to pay Base Monthly Rent or Additional Rent
shall not commence until the such electrical service is provided. If Landlord is
unable to so deliver possession of the Building Shell to Tenant in the agreed
condition on the dates specified, Landlord shall not be in default under this
Lease, nor shall this Lease be void, voidable or cancelable by Tenant until the
lapse of sixty (60) days after the Effective Date of this Lease (the "delivery
grace period"). If Landlord is unable to deliver possession of the Leased
Premises- in the agreed condition to Tenant within the described delivery grace
period (including any extension thereof by reason of Force Majeure or the
actions or inactions of Tenant), then Tenant's sole remedy shall be to terminate
this Lease, and in no event shall Landlord be liable in damages to Tenant for
such delay. Tenant may not terminate this Lease at any time after the date
Landlord notifies Tenant that the Leased Premises have been put into the agreed
condition and are available for delivery to Tenant, unless Landlord's notice is
not given in good faith.

letter attached to and made a part of this Lease (the "Work Letter"), perform
the work described as "Building Shell" substantially as Set forth in the Work
Letter.  Tenant shall, pursuant to the Work Letter, perform the work described
as "Improvement Work" substantially as set forth in the Work Letter.  During
Tenant's construction of the Improvement Work, Tenant shall comply with all of
the terms and conditions of this Lease (including, without limitation, all
insurance requirements), provided that no Base Monthly Rent or Additional Rent
shall be due prior to the Lease Commencement Date.

2.6  Surrender Of Possession.

     (a)  Upon the expiration or upon the sooner termination of this Lease,
Tenant shall remove all of Tenant's signs from the exterior of the Building and,
subject to Section 6.2 below, shall remove all of Tenant's equipment, trade
fixtures, furniture, supplies, wall decorations and other personal property from

10) excepted. Tenant shall repair all damage to the Leased Premises, the
exterior of the Building and the Outside Areas caused by Tenant's removal of
Tenant's property. Tenant shall patch and refinish, to Landlord's reasonable
satisfaction, all penetrations made by Tenant or its employees to the floor,
walls or ceiling of the Leased Premises, whether such penetrations were made
with Landlord's approval or not. Tenant shall repair or replace all stained or
damaged ceiling tiles, wall coverings and floor coverings to the reasonable
satisfaction of Landlord. Tenant shall repair all damage caused by Tenant to the

and, where necessary, replace or resurface same. Tenant shall, subject to
Section 6.2 below, remove all Specialized Improvements (as defined in the Work
Letter) identified by Landlord pursuant to the Work Letter and shall repair all
damage to the Leased Premises, the Building and the Property caused by the

without limiting the foregoing, Landlord may requite that Tenant remove any
improvements, alterations or modifications to the Leased Premises, the Building
or the Outside Areas to the extent (a) Tenant made such improvements,
alterations or modifications without Landlord's consent as permitted by
Paragraph 6.1, and (b) Tenant either (1) failed to request a determination by
Landlord at the time the improvements, alterations or modifications were made as
to whether the improvements, alterations or modifications could remain the
expiration or earlier termination of this Lease or (2) requested such
determination and Landlord notified Tenant at that time that the improvements,
alterations or modifications-must be removed at the expiration or earlier
termination of the Lease.

  (b) If the Leased Premises, the Building, the Outside Areas and the Property
are not surrendered to Landlord in the condition required by this paragraph at
the expiration or sooner termination of this Lease, Landlord may, at Tenant's
expense, so remove Tenant's signs, property and/or improvements not so removed
and make such repairs and replacements not so made or hire, at Tenant's expense,
independent contractors to perform such work.  Tenant shall be liable to
Landlord for all costs incurred by Landlord in returning the Leased Premises,
the Building and the Outside Areas to the required condition, together with
interest on all costs so incurred from the date paid by Landlord at the then
maximum rate of interest not prohibited or made usurious by law until paid.
Tenant shall pay to Landlord the amount of all costs so incurred plus such
interest thereon, within ten (10) days of Landlord's billing Tenant for same.
Tenant shall indemnify Landlord against loss or liability resulting from delay
by Tenant in surrendering the Leased Premises, including, without limitation,
any claims made by any succeeding Tenant or any losses to Landlord with respect

ARTICLE 3
RENT, LATE CHARGES AND SECURITY DEPOSITS

3.1  Base Monthly Rent. Commencing on the Lease Commencement Date (as determined
pursuant to Paragraph 2.3 above) and continuing throughout the Lease Term,
Tenant shall pay to Landlord, without prior demand therefor, in advance on the
first day of each calendar month, the amount set forth as "Base Monthly Rent" in
Article 1 (the "Base Monthly Rent"). In no event shall Base Monthly Rent
payments commence prior to the date Landlord delivers to Tenant the Building
Shell in accordance with the terms of this Lease.

3.2  Additional Rent. Commencing on the Lease Commencement Date (as determined
pursuant to Paragraph 2.3 above) and continuing throughout the Lease Term, in
addition to the Base Monthly Rent and to the extent not required by Landlord to
be contracted for and paid directly by Tenant, Tenant shall pay to Landlord as
additional rent (the "Additional Rent") the following amounts:

       (a) An amount equal to all Property operating Expenses (as defined in
Article 13) incurred by Landlord. Landlord shall deliver to Tenant Landlord's
reasonable estimate of any given expense (such as Landlord's Insurance Costs or
Real Property Taxes), or group of expenses, which it anticipates will be paid or
incurred for the ensuing calendar or fiscal year, as Landlord may determine, and
Tenant shall pay to Landlord an amount equal to the estimated amount of such
expenses for such year in equal monthly installments during such year with the
installments of Base Monthly Rent. Landlord reserves the right to change from
time to time (but not more frequently than once per year) the methods of billing
Tenant for any given expense or group of expenses or the periodic basis on which
such expenses are billed.

       (b) Landlord's share of the consideration received by Tenant upon certain
assignments and sublettings as required by Article 7.

                                       5
<PAGE>

       (c) Any legal fees and costs that Tenant is obligated to pay or reimburse
to Landlord pursuant to Article 13; and

       (d) Any other charges or reimbursements due Landlord from Tenant pursuant
to the terms of this Lease.

Notwithstanding the foregoing, Landlord may elect by written notice to Tenant to
have Tenant pay Real Property Taxes or any portion thereof directly to the
applicable taxing authority, in which case Tenant shall make such payments and
deliver satisfactory evidence of payment to Landlord no later than ten (10) days
before such Real Property Taxes become delinquent.

Tenant may cause an audit of Landlord's books and records to determine the
accuracy of Landlord's billings for Property Operating Expenses under this
Lease, provided Tenant commences such audit within sixty (60) days after
Tenant's receipt of the year-end statement described in Section 3.3 below
setting forth the annual reconciliation of the Property Operating Expenses.  If
such audit reveals that the actual Property Operating Expenses for any given
year were less than the amount that Tenant paid for Property Operating Expenses
for any such year, then Landlord shall pay to Tenant the excess.  If such audit
reveals a discrepancy of more than three (3%) percent of the actual amount of
any Property Operating Expenses charges, then Landlord shall pay the cost of the
audit.

                                       6
<PAGE>

3.3  Year-End Adjustments. If Landlord shall have elected to bill Tenant for:
the Property Operating Expenses (or any group of such expenses) on an estimated
basis in accordance with the provisions of Paragraph 3.2(a)(iii) above, Landlord
shall furnish to Tenant within three months following the end of the applicable
calendar or fiscal year, as the case may be, a statement setting forth (i) the
amount of such expenses paid or incurred during the just ended calendar or
fiscal year, as appropriate, and (ii) the amount that Tenant has paid to
Landlord for credit against such expenses for such period. If Tenant shall have
paid more than its obligation for such expenses for the stated period, Landlord
shall, at its election, either (i) credit the amount of such overpayment toward
the next ensuing payment or payments of Additional Rent that would otherwise be
due or (ii) refund in cash to Tenant the amount of such overpayment. If such
year-end statement shall show that Tenant did not pay its obligation for such
expenses in full, then Tenant shall pay to Landlord the amount of such
underpayment within thirty (30) days from Landlord's billing of same to Tenant.
The provisions of this Paragraph shall survive the expiration or sooner
termination of this Lease.

3.4  Late Charge, And Interest On Rent In Default. Tenant acknowledges that the
late payment by Tenant of any monthly installment of Base Monthly Rent or any
Additional Rent will cause Landlord to incur certain costs and expenses not
contemplated under this Lease, the exact amounts of which are extremely
difficult or impractical to fix. Such costs and expenses will include without
limitation, administration and collection Costs and processing and accounting
expenses. Therefore, if any installment of Base Monthly Rent is not received by
Landlord from Tenant within ten (10) calendar days after the same becomes due,
Tenant shall immediately pay to Landlord slate charge in an amount equal to the
amount set forth in Article 1 as the "Late Charge Amount," and if any Additional
Rent is not received by Landlord within ten (10) calendar days after same
becomes due, Tenant shall immediately pay to Landlords late charge in an amount
equal to 5% of the Additional Rent not so paid. Landlord and Tenant agree that
this late charge represents a reasonable estimate of such Costs and expenses and
is fair compensation to Landlord for the anticipated loss Landlord would suffer
by reason of Tenant's failure to make timely payment. In no event shall this
provision for a late charge be deemed to grant to Tenant a grace period or
extension of time within which to pay any rental installment or prevent Landlord
from exercising any right or remedy available to Landlord upon Tenant's failure
to pay each rental installment due under this Lease when due, including the
right to terminate this Lease. If any rent remains delinquent for a period in
excess of ten (10) calendar days, then, in addition to such late charge, Tenant
shall pay to Landlord interest on any rent that is not so paid from said tenth
(10th) day at the then maximum rate of interest not prohibited or made usurious
by Law until paid.

3.5  Payment Of Rent. Except as specifically provided otherwise in this Lease,
all rent shall be paid in lawful money of the United States, without any
abatement, reduction or offset for any reason whatsoever, to Landlord at such
address as Landlord may designate from time to time. Tenant's obligation to pay
Base Monthly Rent and all Additional Rent shall be appropriately prorated at the
commencement and expiration of the Lease Term. The failure by Tenant to pay any
Additional Rent as required pursuant to this Lease when due shall be treated the
same as a failure by Tenant to pay Base Monthly Rent when due, and Landlord
shall have the same rights and remedies against Tenant as Landlord would have
had Tenant failed to pay the Base Monthly Rent when due.

3.6  Prepaid Rent. Tenant shall, upon execution of this Lease, pay to Landlord
the amount set forth in Article 1 as "First Month's Prepaid Rent" as prepayment
of rent for credit against the first payment of Base Monthly Rent due hereunder.

3.7  Security Deposit. Tenant has deposited or shall deposit with Landlord the
amount Set forth in Article 1 as the "Security Deposit" as security for the
performance by Tenant of the terms of this Lease to be performed by Tenant, and
not as prepayment of rent.

        (a) Landlord may apply such portion or portions of the Security Deposit
as are reasonably necessary for the following purposes: (i) to remedy any
default by Tenant in the payment of Base Monthly Rent or Additional Rent or a
late charge or interest on defaulted rent, or any other monetary payment
obligation of Tenant under this Lease; (ii) to repair damage to the Leased
Premises, the Building or the Outside Areas caused or permitted to occur by
Tenant; (iii) to clean and restore and repair the Leased Premises, the Building
or the Outside Areas following their surrender to Landlord if not surrendered in
the condition required pursuant to the provisions of Article 2, and (iv) to
remedy any other default of Tenant to the extent permitted by Law including,
without limitation, paying in full on Tenant's behalf any sums claimed by
materialmen or contractors of Tenant to be owing to them by Tenant for work done
or improvements made at Tenant's request to the Leased Premises. In this regard,
Tenant hereby waives any restriction on the uses to which the Security Deposit
may be applied as contained in Section 1950.7(c) of the

                                       7
<PAGE>

California Civil Code and/or any successor Statute. In the event the Security
Deposit or any portion thereof is so used, Tenant shall pay to Landlord,
promptly upon demand, an amount in cash Sufficient to restore the Security
Deposit to the full original sum. If Tenant fails to promptly restore the
Security Deposit and if Tenant shall have paid to Landlord any sums as "Last
Month's Prepaid Rent," Landlord may, in addition to any other remedy Landlord
may have under this Lease, reduce the amount of Tenant's Last Month's Prepaid
Rent by transferring all or portions of such Last Month's Prepaid Rent to
Tenant's Security Deposit until such Security Deposit is restored to the amount
set forth in Article 1. Landlord shall not be deemed a trustee of the Security
Deposit. Landlord may use the Security Deposit in Landlord's ordinary business
and shall not be required to segregate it from Landlord's general accounts.
Tenant shall not be entitled to any interest on the Security Deposit. If
Landlord transfers the Building or the Property during the Lease Term, Landlord
may pay the Security Deposit to any subsequent owner in conformity with the
provisions of Section 1950.7 of the California Civil Code and/or any successor
statute, in which event the transferring landlord shall be released from all
liability for the return of the Security Deposit. Tenant specifically grants to
Landlord (and Tenant hereby waives the provisions of California Civil Code
Section 1950.7 to the contrary) a period of forty five (45) days following a
surrender of the Leased Premises by Tenant to Landlord within which to inspect
the Leased Premises, obtain cost estimates for required restorations and
repairs, receive and verily workmen's billings therefor, and prepare a final
accounting with respect to the Security Deposit. In no event shall the Security
Deposit or any portion thereof, be considered prepaid rent.

     (b) Provided that Tenant is not then in default beyond any applicable
notice and cure period under this Lease (and has not been in default beyond any
applicable notice and cure period more than three (3) times during the Term of
this Lease), the Security Deposit shall be reduced by an amount equal to one
hundred forty four thousand ($144,000) commencing on the first day of the
thirteenth month of the Lease Term, and on each anniversary of such day, until
such time as the Security Deposit is equal to two (2) months' Base Monthly Rent
(determined based on the Base Monthly Rent payable at the time of such final
reduction).

     (c) Notwithstanding clause (b) above, in the event Tenant records a profit
for two consecutive quarters (as shown on its quarterly financial statements
prepared in accordance with generally accepted accounting principles), and
provided that Tenant is not then in default beyond any applicable notice and
cure period under this Lease (and has not been in default beyond any applicable
notice and cure period more than three (3) times during the Term of this Lease),
the Security Deposit shall be reduced to an amount equal to one (1) month's Base
Monthly Rent (determined based on the Base Monthly Rent payable at the time of
such reduction).

     (d) Notwithstanding clauses (b) and (c) above, in the event Tenant achieves
a "BB" credit rating from Standard & Poors, Moody's, or another rating agency
reasonably acceptable to Landlord, and provided that Tenant is not then in
default beyond any applicable notice and cure period under this Lease (and has
not been in default beyond any applicable notice and cure period more than three
(3) times during the Term of this Lease), the Security Deposit shall be reduced
to an amount equal to one (I) month's Base Monthly Rent (determined based on the
Base Monthly Rent payable at the time of such reduction).

     (e) Tenant may elect to maintain the Security Deposit in the form of a
letter of credit ("Letter of Credit") in lieu of cash, provided the following
conditions are met: The Letter of Credit shall be issued by and drawable upon
the Santa Clara office of Silicon Valley Bank. The Letter of Credit shall be in
a form acceptable to Landlord, name Landlord as beneficiary, be in the amount of
the Security Deposit, have a term of not less than one (1) year, permit multiple
drawings, be fully transferable by Landlord and otherwise be substantially in
the form of Exhibit F attached hereto.. If upon any transfer, any fees or
charges shall be imposed, then such fees or charges shall be payable solely by
Landlord and the Letter of Credit shall so specify. Tenant shall not less than
thirty (30) days prior to its expiry date replace the Letter of Credit with a
new Letter of Credit with a term of not less than one (1) year and otherwise
complying with the requirements of this Paragraph 3(e). If not later than thirty
(30) days prior to the expiry date of the Letter of Credit Tenant fails to
furnish to Landlord a replacement letter of credit in accordance with the terms
of this Paragraph 3(e), then Landlord shall have the right to draw the full
amount of the Letter of Credit, by sight draft on the Issuing Bank, and shall
hold the proceeds of the Letter of Credit pursuant to the terms of this
Paragraph 3(e) as a cash security deposit; provided, however, should Tenant
thereafter furnish to Landlord a Letter of Credit meeting the requirements of
this Paragraph 3(e), such cash proceeds, less all expenses incurred by Landlord,
shall be returned to Tenant. The Letter of Credit may, at Tenant's Option, be
replaced by a different Letter of Credit from a different issuing bank, provided
that the form of such replacement Letter of Credit shall be acceptable to
Landlord in

                                       8
<PAGE>

Landlord's sole discretion, and such issuing bank shall be acceptable to
Landlord in Landlord's reasonable discretion.

entitled to vote for the election of directors.  If Tenant is a partnership, a
withdrawal or change, voluntary.  involuntary or by operation of Law, of any
general partner, or the dissolution of the partnership, shall be deemed a
voluntary assignment of Tenant's interest in this Lease.  Notwithstanding the
foregoing, Tenant may, without Landlord's prior written consent, sublet the
Leased Premises or assign this Lease to (individually, a "Permitted Assignee,"
collectively, "Permitted Assignees"): (i) a subsidiary, affiliate, division,
corporation or joint venture controlling, controlled by or under common control
with Tenant; or (ii) a successor corporation related to Tenant by merger,
consolidation, nonbankruptcy reorganization, or government action; provided that
any Permitted Assignee under (i) or (ii) above has the financial capability to
perform Tenant's obligations under this Lease.

7.3  Landlord's Election. If Tenant shall desire to assign its interest under
the Lease or to sublet the Leased Premises, Tenant must first notify Landlord,
in writing, of its intent to so assign or sublet, at least thirty (30) days in
advance of the date it intends to so assign its interest in this Lease or sublet

of such date, specifying in detail the terms of such proposed assignment or
subletting, including the name of the proposed assignee or sublessee, the

financial statements (including a balance sheet, income statement and statement
of cash flow, all prepared in accordance with generally accepted accounting
principles) of such proposed assignee or sublessee, the form of documents to be
used in effectuating such assignment or subletting and such other information as
Landlord may reasonably request. Landlord shall have a period often (10)

within which to do one of the following: (i) consent to such requested
assignment or subletting subject to Tenant's compliance with the conditions set

requested assignment or subletting, such consent shall be expressly conditioned
upon the occurrence of each of the conditions below set forth, and any purported
assignment or subletting made or ordered prior to the full and complete
satisfaction of each of the following conditions shall be void and, at the
election of Landlord, which election may be exercised at any time following such
a purported assignment or subletting but prior to the satisfaction of each of
the stated conditions, shall constitute a material default by Tenant under this
Lease until cured by satisfying in full each such condition by the assignee or
sublessee.  The conditions are as follows:

assignee at the time of the assignment, that Tenant shall have paid to Landlord
and Landlord shall have received an amount equal to fifty percent (50%) of the
assignment consideration so paid or to be paid (whichever is the greater) at the
time of the assignment by the assignee; or

          (ii)      If Tenant assigns its interest under this Lease and if
Tenant is to receive all or a portion of the consideration for such assignment
in future installments, that Tenant and Tenant's assignee shall have entered
into a written agreement with and for the benefit of Landlord satisfactory to
Landlord and its counsel whereby Tenant and Tenant's assignee jointly agree to
pay to Landlord an amount equal to fifty percent (50%) of all such future
assignment consideration installments to be paid by such assignee as and when
such assignment consideration is so paid.

          (iii)     If Tenant subleases the Leased Premises, that Tenant and
Tenant's sublessee shall have entered into a written agreement with and for the

7.5  Assignment Consideration And Excess Rentals Defined.  For purposes of this
Article, including any amendment to this Article by way of addendum or other
writing, the term "assignment consideration" shall mean all consideration to be
paid by the assignee to Tenant pr to any other party on Tenant's behalf or for
Tenant's benefit as consideration for such assignment, after deduction for
reasonable leasing commissions paid by Tenant but without deductions for any
other costs or expenses (including, without limitation, tenant improvements,
capital improvements, building upgrades, permit fees, attorneys' fees, and other
consultants' fees) incurred by Tenant in connection with such assignment, and
the term "excess rentals" shall mean all consideration to be paid by the sub
lessee to Tenant or to any other party on Tenant's behalf or for Tenant's
benefit for the sublease of the Leased Premises in excess of the rent due to
Landlord under the terms of this Lease for the same period, after deduction
reasonable leasing commissions paid by Tenant (amortized over the term of the
sublease) but without deduction for any other costs or expenses (including,
without limitation, tenant improvements, capital improvements, building
upgrades, permit fees, attorneys' fees, and other consultants' fees) incurred by
Tenant in connection with such sublease.  Tenant agrees that the portion of any
assignment consideration and/or excess rentals arising from any assignment or
subletting by Tenant which is to be paid to Landlord pursuant to this Article
now is and shall then be the property of Landlord and not the property of
Tenant.

7.6  Payments.  All payments required by this Article to be made to Landlord
shall be made in cash in full as and when they become due.  At the time Tenant,
Tenant's assignee or sublessee makes each such payment to Landlord, Tenant or
Tenant's assignee or sublessee, as the case may be, shall deliver to Landlord an
itemized statement in reasonable detail showing the method by which the amount
due Landlord was calculated and certified by the party making such payment as
true and correct.

7.7  Good Faith.  The rights granted to Tenant by this Article are granted in
consideration of Tenant's express covenant that all pertinent allocations which
are made by Tenant between the rental value of the Leased Premises and the value
of any of Tenant's personal property which may be conveyed or leased generally
concurrently with and which may reasonably be considered a part of the same
transaction as the permitted assignment or subletting shall be made fairly,
honestly and in good faith.  If Tenant shall breach this covenant, Landlord may
immediately declare Tenant to be in default under the terms of this Lease and
terminate this Lease and/or exercise any other rights and remedies Landlord
would have under the terms of this Lease in the case of a material default by
Tenant under this Lease.

7.8  Effect Of Landlord's Consent.  No subletting or assignment, even with the
consent of Landlord (and even to a Permitted Assignee) shall relieve Tenant of
its personal and primary obligation to pay rent and to perform all of the other
obligations to be performed by Tenant hereunder.  Consent by Landlord to one or
more assignments of Tenant's interest in this Lease or to one or more
sublettings of the Leased Premises shall not be deemed to be a consent to any
subsequent assignment or subletting.  If Landlord shall have been ordered by a
court of competent jurisdiction to consent to a requested assignment or
subletting, or such an assignment or subletting shall have been ordered by a
court of competent jurisdiction over the objection of Landlord, such assignment
or subletting shall not be binding between the assignee (or sublessee) and
Landlord until such time as all conditions set forth in Paragraph 7.4 above have
been fully satisfied (to the extent not then satisfied) by the assignee or
sublessee, including, without limitation, the payment to Landlord of all agreed
assignment considerations and/or excess rentals then due Landlord.

Tenant acknowledges that it is fully apprised of the provisions of Law relating
to releases, and particularly to those provisions contained in Section 1542 of
the California Civil Code which reads as follows:

          "A general release does not extend to claims which the
          creditor does not know or suspect to exist in his favor at
          the time of executing the release, which if known by him
          must have materially affected his settlement with the debtor."

full and complete release and discharge, Tenant hereby (i) waives the benefit of
such statutory provision and (ii) acknowledges that, subject to the exceptions
specifically set forth herein, the release and discharge set forth in this
paragraph is a full and complete settlement and release and discharge of all

which Tenant, as of the date hereof, does not know of or suspect to exist in its
favor.

from Tenant's use or occupancy of the Leased Premises, the Building or the
Outside Areas, or resulting from Tenant's activities in or about the Leased
Premises, the Building, the Outside Areas or the Property, and Tenant shall
indemnify and hold Landlord, Landlord's partners, principals, members,
employees, agents and contractors harmless from any loss liability, penalties,
or expense whatsoever (including any loss attributable to vacant space which

except to the extent proximately caused by the gross negligence or willful
misconduct of Landlord.  This indemnity agreement shall survive the expiration
or sooner termination of this Lease.

policy of insurance Tenant is required to carry pursuant to this Article 1s not
adequate, then Tenant shall increase the amount of coverage for such insurance
to such greater amount as Landlord's Lender, insurance broker, advisor or
counsel reasonably deems adequate, provided that such

                                       24
<PAGE>

increased coverage amounts are commonly required of tenants with similar
operations (including the use of Hazardous Materials) in similar type buildings
and areas.

9.2  Landlord's Insurance.  With respect to insurance maintained by Landlord:

          (a) Landlord shall maintain, as the minimum coverage required of it by
this Lease, fire and property damage insurance in so-called 'fire and extended

against loss from physical damage to the Building with coverage of not less than
one hundred percent (100%) of the full actual replacement cost thereof and
against loss of rents for a period of not less than six (6) months. Such fire
and property damage insurance, at Landlord's election but without any
requirements on Landlord's behalf to do so, (i) may be written in so-called "all
risk" form, excluding only those perils commonly excluded from such coverage by
Landlord's then property damage insurer; (ii) may provide coverage for physical
damage to the improvements so insured for up to the entire full actual
replacement cost thereof (iii) may be endorsed to cover loss or damage caused by
any additional perils against which Landlord may elect to insure, including
earthquake and/or flood; and/or (iv) may provide coverage for loss of rents for
a period of up to twelve months. Landlord shall not be required to cause such
insurance to cover any of Tenant's personal property, inventory, and trade

reasonable efforts to obtain such insurance at competitive rates.

          (b) Landlord shall maintain commercial general liability insurance
insuring Landlord (and such others as are designated by Landlord) against
liability for personal injury, bodily injury, death, and damage to property
occurring in, on or about, or resulting from the use or occupancy of the

Five Million Dollars ($5,000,000). Landlord may carry such greater coverage as
Landlord or Landlord's Lender, insurance broker, advisor or counsel may from
time to time determine is reasonably necessary for the adequate protection of
Landlord and the Property.

          (c) Landlord may maintain any other insurance which in the opinion of
its insurance broker, advisor or legal counsel is prudent in carry under the
given circumstances, provided such insurance is commonly carried by owners of
property similarly situated and operating under similar circumstances.

hereby releases Landlord and its respective partners, principals, members,
officers, agents, employees and servants, from any and all liability for loss,
damage or injury to the property of the other in or about the Leased Premises or
the Property which is caused by or results from a peril or event or happening
which is covered by insurance actually carried and in force at the time of the
loss by the party sustaining such loss; provided, however, that such waiver
shall be effective only to the extent permitted by the insurance covering such
loss and to the extent such insurance is not prejudiced thereby.

<PAGE>

10.1 Landlord's Duty To Restore.  If the Leased Premises, the Building or the
Outside Area are damaged by any peril after the Effective Date of this Lease,
Landlord shall restore the same, as and when required by this paragraph, unless

pursuant to Paragraph 10.4.  If this Lease is not so terminated, then upon the
issuance of all necessary governmental permits, Landlord shall commence and
diligently prosecute to completion the restoration of the Building Shell or the
Outside Area, as the case may be, to the extent then allowed by law, to

shall be limited to the improvements constructed by Landlord.  Landlord shall
have no obligation to restore the Improvement Work, or any other alterations,
modifications or improvements made by Tenant to the Leased Premises or any of
Tenant's personal property, inventory or trade fixtures.  Upon completion of the
restoration of the Building Shell by Landlord, Tenant shall forthwith at its
expense, replace or fully repair all of the Improvement Work and other
improvements constructed by Tenant to like or similar conditions as existed at
the time immediately prior to such damage or destruction.

10.2 Insurance Proceeds.  All insurance proceeds available from the fire and
property damage insurance carried by Landlord shall be paid to and become the
property of Landlord.  If this Lease is terminated pursuant to either Paragraph
10.3 or 10.4, all insurance proceeds available from insurance carried by Tenant
which cover loss of property that is Landlord's property shall be paid to and
become the property of Landlord, and the remainder of such proceeds shall be
paid to and become the property of Tenant.  In addition, all insurance proceeds
available from insurance carried by Tenant which covers Improvement Work
constructed with the Improvement Allowance, up to a maximum of the present value
of the unamortized Improvement Allowance (determined using an interest rate of
12%), shall be paid to and become the property of Landlord.  If this Lease is
not terminated pursuant to either Paragraph 10.3 or 10.4, all insurance proceeds
available from insurance carried by Tenant which cover loss to property that is
Landlord's property shall be paid to and become the property of Landlord, and
all proceeds available from such insurance which cover loss to property which
would only become the property of Landlord upon the termination of this Lease
shall be paid to and remain the property of Tenant.  The determination of
Landlord's property and Tenant's property shall be made pursuant to Paragraph
6.2.

10.3 Landlord's Right To Terminate.  Landlord shall have the option to terminate
this Lease in the event any of the following occurs, which option may be
exercised only by delivery to Tenant of a written notice of election to
terminate within thirty (30) days after the date of such damage or destruction:

          (a) The Building is damaged by any peril covered by valid and
collectible insurance actually carried by Landlord and in force at the time of
such damage or destruction (an "insured peril") to such an extent that the
estimated cost to restore the Building exceeds the lesser of (i) the insurance
proceeds available from insurance actually carried by Landlord due to all or any
portion of the insurance proceeds being otherwise applied by Landlord's lender,
or (ii) fifty percent of the then actual replacement cost thereof;

          (b) The Building is damaged by an uninsured peril, which peril
Landlord was not required to insure against pursuant to the provisions of
Article 9 of this Lease;

          (c) The Building is damaged by any peril and, because of the laws then
in force, the Building (i) cannot be restored at reasonable cost or (ii) if
restored, cannot be used for the same use being made thereof before such damage;

provided, however, that if Landlord elects to terminate the Lease pursuant to
this Paragraph 10.3, Tenant may elect by written notice to Landlord delivered
within thirty (30) days or receipt of Landlord's election, to pay the difference
between the costs to restore the Building and any available insurance proceeds
and upon such election and Tenant's deposit of such funds with Landlord (or
provide Landlord with a duly authorized and executed recourse promissory note
payable to Landlord in lieu of such funds), Landlord shall commence such
restoration.

                                       26
<PAGE>

10.4 Tenant's Right To Terminate.  If the Leased Premises, the Building or the
Outside Area are damaged by any peril and Landlord does not elect to terminate
this Lease or is not entitled to terminate this Lease pursuant to this Article,
then as soon as reasonably practicable, Landlord shall furnish Tenant with the
written opinion of Landlord's architect or construction consultant as to when
the restoration work required of Landlord may be complete.  Tenant shall have
the option to terminate this Lease in the event any of the following occurs,
which option may be exercised only by delivery to Landlord of a written notice
of election to terminate within thirty (30) days after Tenant receives from
Landlord the estimate of the time needed to complete such restoration:

          (a) If the time estimated to substantially complete the restoration
exceeds nine (9) months from and after the date the architect's or construction
consultant's written opinion is delivered; or

          (b) If the damage occurred within eighteen (18) months of the last day
of the Lease Term and the time estimated to substantially complete the
restoration exceeds one hundred eighty (180) days from and after the date such
restoration is commenced.

10.5 Tenant's Waiver.  Landlord and Tenant agree that the provisions of
Paragraph 10.4 above, captioned "Tenant's Right To Terminate", are intended to
supersede and replace the provisions contained in California Civil Code, Section
1932, Subdivision 2, and California Civil Code, Section 1934, and accordingly,
Tenant hereby waives the provisions of such Civil Code Sections and the
provisions of any successor Civil Code Sections or similar laws hereinafter
enacted.

10.6 Abatement Of Rent.  In the event of damage to the Leased Premises which
does not result in the termination of this Lease, the Base Monthly Rent (and any
Additional Rent) shall be temporarily abated from the date of such damage or
destruction through the period of restoration of the Building Shell in
proportion to the degree to which Tenant's use of the Leased Premises is
impaired by such damage.

Landlord and Tenant shall be determined in accordance with Paragraphs 11.1 and
11.2 above.

11.5 Division Of Condemnation Award. Any award made for any taking of the
Property, the Building, or the Leased Premises, or any portion thereof, shall
belong to and be paid to Landlord, and Tenant hereby assigns to Landlord all of
its right, title and interest in any such award; provided, however, that Tenant
shall be entitled to receive any portion of the award that is made specifically
(i) for the taking of personal property, inventory or trade fixtures belonging
to Tenant, (ii) for the interruption of Tenant's business or its moving costs,
or (iii) for the value of any leasehold improvements installed and paid for by
Tenant. The rights of Landlord and Tenant regarding any condemnation shall be
determined as provided in this Article, and each party hereby waives the
provisions of Section 1265.130 of the California Code of Civil Procedure, and
the provisions of any similar law hereinafter enacted, allowing either party to
petition the Supreme Court to terminate this Lease and/or otherwise allocate
condemnation awards between Landlord and Tenant in the event of a taking of the
Leased Premises.

11.6 Abatement Of Rent. In the event of a taking of the Leased Premises which
does not result in a termination of this Lease (other than a temporary taking),
then, as of the date possession is taken by the condemning authority, the Base
Monthly Rent shall be reduced in the same proportion that the area of that part
of the Leased Premises so taken (less any addition to the area of the Leased
Premises by reason of any reconstruction) bears to the area of the Leased
Premises immediately prior to such taking.

11.7 Taking Defined. The term "taking" or "taken" as used in this Article 11
shall mean any transfer or conveyance of all or any portion of the Property to a
public or quasi-public agency or other entity having the power of eminent domain
pursuant to or as a result of the exercise of such power by such an agency,
including any inverse condemnation and/or any sale or transfer by Landlord of
all or any portion of the Property to such an agency under threat of
condemnation or the exercise of such power.

after written notice from Landlord to Tenant specifying the nature of such
failure and requesting Tenant to perform same or within such longer period as is

filed a petition seeking liquidation or reorganization under said bankruptcy
laws or any other debtor's relief law or similar statute of the United States or

  (h) Tenant or any Guarantor of this Lease shall have availed itself of the
protection of any debtor's relief law, moratorium law or other similar law which
does not require the prior entry of a decree or order.

12.2 Landlord's Remedies. In the event of any default by Tenant, and without
limiting Landlord's right to indemnification as provided in Article 8.2,
Landlord shall have the following remedies, in addition to all other rights and
remedies provided by law or otherwise provided in this Lease, to which Landlord
may resort cumulatively, or in the alternative:

  (a) Landlord may, at Landlord's election, keep this Lease in effect and
enforce, by an action at law or in equity, all of its rights and remedies under
this Lease including, without limitation, (i) the right to recover the rent and
other sums as they become due by appropriate legal action, (ii) the right to
make payments required by Tenant, or perform Tenant's obligations and be
reimbursed by Tenant for the cost thereof with interest at the then maximum

                                       29
<PAGE>

rate of interest not prohibited by law from the date the sum is paid by Landlord
until Landlord is reimbursed by Tenant, and (iii) the remedies of injunctive
relief and specific performance to prevent Tenant from violating the terms of
this Lease and/or to compel Tenant to perform its obligations under this Lease,
as the case may be.

  (b) Landlord may, at Landlord's election, terminate this Lease by giving
Tenant written notice of termination, in which event this Lease shall terminate
on the date Set forth for termination in such notice, in which event Tenant
shall immediately surrender the Leased Premises to Landlord, and if Tenant fails
to do so, Landlord may, without prejudice to any other remedy which it may have
for possession or arrearages in rent, enter upon and take possession of the
Leased Premises and expel or remove Tenant and any other person who may be
occupying the Leased Premises or any part thereof, without being liable for
prosecution or any claim or damages therefor. Any termination under this
subparagraph shall not relieve Tenant from its obligation to pay to Landlord all
Base Monthly Rent and Additional Rent then or thereafter due, or any other sums
due or thereafter accruing to Landlord, or from any claim against Tenant for
damages previously accrued or then or thereafter accruing. In no event shall any
one or more of the following actions by Landlord, in the absence of a written
election by Landlord to terminate this Lease constitute a termination of this
Lease:

      (i)   Appointment of a receiver or keeper in order to protect Landlord's
interest hereunder;

      (ii)  Consent to any subletting of the Leased Premises or assignment of
this Lease by Tenant, whether pursuant to the provisions hereof or otherwise; or

      (iii) Any action taken by Landlord or its partners, principals, members,
officers, agents, employees, or servants, which is intended to mitigate the
adverse effects of any breach of this Lease by Tenant, including, without
limitation, any action taken to maintain and preserve the Leased Premises on any
action taken to re let the Leased Premises or any portion thereof for the
account at Tenant and in the name of Tenant.

  (c) In the event Tenant breaches this Lease and abandons the Leased Premises,
Landlord may terminate this Lease, but this Lease shall not terminate unless
Landlord gives Tenant written notice of termination. If Landlord does not
terminate this Lease by giving written notice of termination, Landlord may
enforce all its rights and remedies under this Lease, including the right and
remedies provided by California Civil Code Section 1951.4 ("lessor may continue
lease in effect after lessee's breach and abandonment and recover rent as it
becomes due, if lessee has right to sublet or assign, subject only to reasonable
limitations"), as in effect on the Effective Date of this Lease.

  (d) In the event Landlord terminates this Lease, Landlord shall be entitled,
at Landlord's election, to the rights and remedies provided in California Civil
Code Section 1951.2, as in effect on the Effective Date of this Lease. For
purposes of computing damages pursuant to Section 1951.2, an interest rate equal
to the maximum rate of interest then not prohibited by law shall be used where
permitted. Such damages shall include, without limitation:

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

      (ii)  The worth at the time of award of the amount by which the unpaid
rent for the balance of the term alter the time of award exceeds the amount of
such rental loss that Tenant proves could be reasonably avoided, computed by
discounting such amount at the discount rate of the Federal Reserve Bank of San
Francisco, at the time of award plus one percent; and

      (iii) Any other amount necessary to compensate Landlord for all detriment
proximately caused by Tenant's failure to perform Tenant's obligations under
this Lease, or which in the ordinary course of things would be likely to result
therefrom, including without limitation, the following.. (i) expenses for
cleaning, repairing or restoring the Leased Premises, (ii) expenses for
altering, remodeling or otherwise improving the Leased Premises for the purpose
of reletting, including removal of existing leasehold improvements and/or
installation of additional leasehold improvements (regardless of how the same is
funded, including reduction of rent, a direct payment or allowance to a new
tenant, or otherwise), (iii) broker's fees allocable to the remainder of the
term of this

                                       30
<PAGE>

Lease, advertising costs and other expenses of reletting the Leased Premises;
(iv) costs of carrying and maintaining the Leased Premises, such as taxes,
insurance premiums, utility charges and security precautions, (v) expenses
incurred in removing, disposing of and/or storing any of Tenant's personal
property, inventory or trade fixtures remaining therein; (vi) reasonable
attorney's fees, expert witness fees, court costs and other reasonable expenses
incurred by Landlord (but not limited to taxable costs) in retaking possession
of the Leased Premises, establishing damages hereunder, and releasing the Leased
Premises; and (vii) any other expenses, costs or damages otherwise incurred or
suffered as a result of Tenant's default.

12.3 Landlord's Default And Tenant's Remedies. In the event Landlord fails to
perform its obligations under this Lease, Landlord shall nevertheless not be in
default under the terms of this Lease until such time as Tenant shall have first
given Landlord written notice specifying the nature of such failure to perform
its obligations, and then only after Landlord shall have had thirty (30) days
following its receipt of such notice within which to perform such obligations;
provided that, if longer than thirty (30) days is reasonably required in order
to perform such obligations, Landlord shall have such longer period. In the
event of Landlord's default as above set forth, then, and only then, Tenant may
then proceed in equity or at law to compel Landlord to perform its obligations
and/or to recover damages proximately caused by such failure to perform (except
as and to the extent Tenant has waived its right to damages as provided in this
Lease).

12.4 Limitation or Tenant's Recourse. If Landlord is a corporation, trust,
partnership, joint venture, limited liability company, unincorporated
association, or other form of business entity, Tenant agrees that (i) the
obligations of Landlord under this Lease shall not constitute personal
obligations of the officers, directors, trustees, partners, joint venturers,
members, owners, stockholders, or other principals of such business entity, and
(ii) Tenant shall have recourse only to the property of such corporation, trust,
partnership, joint venture, limited liability company, unincorporated
association, or other form of business entity for the satisfaction of such
obligations and not against the assets of such officers, directors, trustees,
partners, joint venturers, members, owners, stockholders or principals.
Additionally, if Landlord is a partnership or limited liability company, then
Tenant covenants and agrees:

  (a) No partner or member of Landlord shall be sued or named as a party in any
Suit or action brought by Tenant with respect to any alleged breach of this
Lease (except to the extent necessary to secure jurisdiction over the
partnership and then only for that sole purpose);

  (b) No service of process shall be made against any partner or member of
Landlord except for the sole purpose of securing jurisdiction over the
partnership; and

  (c) No writ of execution will ever be levied against the assets of any partner
or member of Landlord other than to the extent of his or her interest in the
assets of the partnership or limited liability company constituting Landlord.

Tenant further agrees that each of the foregoing covenants and agreements shall
be enforceable by Landlord and by any partner or member of Landlord and shall be
applicable to any actual or alleged misrepresentation or nondisclosure made
regarding this Lease or the Leased Premises or any actual or alleged failure,
default or breach of any covenant or agreement either expressly or implicitly
contained in this Lease or imposed by statute or at common law.

12.5 Tenant's Waiver. Landlord and Tenant agree that the provisions of Paragraph
12.3 above are intended to supersede and replace the provisions of California
Civil Code Sections 1932(1), 1941 and 1942, and accordingly, Tenant hereby
waives the provisions of California Civil Code Sections 1932(1), 1941 and 1942
and/or any similar or successor law regarding Tenant's right to terminate this
Lease or to make repairs and deduct the expenses of such repairs from the rent
due under this Lease.

ARTICLE 13
GENERAL PROVISIONS

                                       31
<PAGE>

13.1 Taxes On Tenant's Property. Tenant shall pay before delinquency any and all
taxes, assessments, license fees, use fees, permit fees and public charges of
whatever nature or description levied, assessed or imposed against Tenant or
Landlord by a governmental agency arising Out of, caused by reason of or based
upon Tenant's estate in this Lease, Tenant's ownership of property, improvements
made by Tenant to the Leased Premises or the Outside Areas, improvements made by
Landlord for Tenant's use within the Leased Premises or the Outside Areas,
Tenant's use (or estimated use) of public facilities or services or Tenant's
consumption (or estimated consumption) of public utilities, energy, water or
other resources (collectively, "Tenant's Interest"). Upon demand by Landlord,
Tenant shall famish Landlord with satisfactory evidence of these payments. If
any such taxes, assessments, fees or public charges are levied against Landlord,
Landlord's property, the Building or the Property, or if the assessed value of
the Building or the Property is increased by the inclusion therein of a value
placed upon Tenant's Interest, regardless of the validity thereof Landlord shall
have the right to require Tenant to pay such taxes, and if not paid and
satisfactory evidence of payment delivered to Landlord at least ten days prior
to delinquency, then Landlord shall have the right to pay such taxes on Tenant's
behalf and to invoice Tenant for the same. Tenant shall, within the earlier to
occur of (a) thirty (30) days of the date it receives an invoice from Landlord
setting forth the amount of such taxes, assessments, fees, or public charge so
levied, or (b) the due date of such invoice, pay to Landlord, as Additional
Rent, the amount set forth in such invoice. Failure by Tenant to pay the amount
so invoiced within such time period shall be conclusively deemed a default by
Tenant under this Lease. Tenant shall have the right to bring Suit in any court
of competent jurisdiction to recover from the taxing authority the amount of any
such taxes, assessments, fees or public charges so paid.

13.2 Holding Over. This Lease shall terminate without further notice on the
Lease Expiration Date (as set forth in Article 1). Any holding over by Tenant
after expiration of the Lease Term shall neither constitute a renewal nor
extension of this Lease nor give Tenant any rights in or to the Leased Premises
except as expressly provided in this Paragraph. Any such holding over to which
Landlord has consented shall be construed to be a tenancy from month to month,
on the same terms and conditions herein specified insofar as applicable, except
that the Base Monthly Rent shall be increased to an amount equal to one hundred
fifty percent (150%) of the Base Monthly Rent payable during the last full month
immediately preceding such holding over Tenant acknowledges that if Tenant holds
over without Landlord's consent, such holding over may compromise or otherwise
affect Landlord's ability to enter into new leases with prospective tenants
regarding the Leased Premises. Therefore, if Tenant fails to surrender the
Leased Premises upon the expiration or termination of this Lease, in addition to
any other liabilities to Landlord accruing therefrom, Tenant shall protect,
defend, indemnify and hold Landlord harmless from and against all claims
resulting from such failure, including, without limiting the foregoing, any
claims made by any succeeding tenant founded upon such failure to surrender, and
any losses suffered by Landlord, including lost profits, resulting from such
failure to surrender.

<PAGE>

13.3 Subordination To Mortgages. This Lease is subject to and subordinate to all
ground leases, mortgages and deeds of trust which affect the Building or the
Property and which are of public record as of the Effective Date of this Lease,
and to all renewals, modifications, consolidations, replacements and extensions
thereof. However, if the lessor under any such ground lease or any lender
holding any such mortgage or deed of trust shall advise Landlord that it desires
or requires this Lease to be made prior and superior thereto, then, upon written
request of Landlord to Tenant, Tenant shall promptly execute, acknowledge and
deliver any and all customary or reasonable documents or instruments which
Landlord and such lessor or lender deems necessary or desirable to make this
Lease prior thereto Tenant hereby consents to Landlord's ground leasing the land
underlying the Building or the Property and/or encumbering the Building or the
Property as security for future loans on such terms as Landlord shall desire,
all of which future ground leases, mortgages or deeds of trust shall be subject
to and subordinate to this Lease. However, if any lessor under any such future
ground lease or any lender holding such future mortgage or deed of trust shall
desire or require that this Lease be made subject to and subordinate to such
future ground lease, mortgage or deed of trust, then Tenant agrees, within ten
days after Landlord's written request therefor, to execute, acknowledge and
deliver to Landlord any and all documents or instruments requested by Landlord
or by such lessor or lender as may be necessary or proper to assure the
subordination of this Lease to such future ground lease, mortgage or deed of
trust, but only if such lessor or lender agrees in writing to recognize Tenant's
rights under this Lease and agrees not to disturb Tenant's quiet possession of
the Leased Premises so long as Tenant is not in default under this Lease. If
Landlord assigns the Lease as security for a loan, Tenant agrees to execute such
documents as are reasonably requested by the lender and to provide reasonable
provisions in the Lease protecting such lender's security interest which are
customarily required by institutional lenders making loans secured by a deed of
trust. Landlord agrees to obtain a standard subordination, non-disturbance and
attornment agreement from the existing lender holding the deed of trust
encumbering the Property.

13.4 Tenant's Attornment Upon Foreclosure. Tenant shall, upon request, attorn
(i) to any purchaser of the Building or the Property at any foreclosure sale or
private sale conducted pursuant to any security instruments encumbering the
Building or the Property, (ii) to any grantee or transferee designated in any
deed given in lieu of foreclosure of any security interest encumbering the
Building or the Property, or (iii) to the lessor under an underlying ground
lease of the land underlying the Building or the Property, should such ground
lease be terminated; provided that such purchaser, grantee or lessor agrees in
writing to recognize Tenant's rights under this Lease and agrees not to disturb
Tenant's quiet possession of the Leased Premises so long as Tenant is not in
default hereunder.

13.5 Mortgagee Protection. In the event of any default on the part of Landlord,
Tenant will give notice by registered mail to any Lender or lessor under any
underlying ground lease who shall have requested, in writing, to Tenant that it
be provided with such notice, and Tenant shall offer such Lender or lessor a
reasonable opportunity to cure the default, including time to obtain possession
of the Leased Premises by power of sale or judicial foreclosure or other
appropriate legal proceedings if reasonably necessary to effect a cure.

13.6 Estoppel Certificate. Tenant will, following any request by Landlord,
promptly execute and deliver to Landlord an estoppel certificate substantially
in form attached as Exhibit C, (i) 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, (ii) stating the date to which the rent and other charges are paid
in advance, if any, (iii) acknowledging that there are not, to Tenant's
knowledge, any uncured defaults on the part of Landlord hereunder, or specifying
such defaults if any are claimed, and (iv) certifying such other information
about this Lease as may be reasonably requested by Landlord, its Lender or
prospective lenders, investors or purchasers of the Building or the Property.
Tenant's failure to execute and deliver such estoppel certificate within ten
(10) business days after Landlord's request therefor shall be a material default
by Tenant under this Lease, and Landlord shall have all of the rights and
remedies available to Landlord as Landlord would otherwise have in the case of
any other material default by Tenant, including the right to terminate this
Lease and sue for damages proximately caused thereby, it being agreed and
understood by Tenant that Tenant's failure to so deliver such estoppel
certificate in a timely manner could result in Landlord being unable to perform
committed obligations to other third parties which were made by Landlord in
reliance upon this covenant of Tenant. Landlord and Tenant intend that any
statement delivered pursuant to this paragraph may be relied upon by any Lender
or purchaser or prospective Lender or purchaser of the Building, the Property,
or any interest in them.

                                       33
<PAGE>

13.7 Tenant's Financial Information. Tenant shall, within ten (10) business days
after Landlord's request therefor, deliver to Landlord a copy of Tenant's (and
any guarantor's) current financial Statements (including a balance sheet, income
statement and statement of cash flow, all prepared in accordance with generally
accepted accounting principles) and any such other information reasonably
requested by Landlord regarding Tenant's financial condition. Landlord shall be
entitled to disclose such financial statements or other information to its
Lender, to any present or prospective principal of or investor in Landlord, or
to any prospective Lender or purchaser of the Building, the Property, or any
portion thereof or interest therein. Any such financial statement or other
information which is marked "confidential" or "company secrets" (or is otherwise
similarly marked by Tenant) shall be confidential and shall not be disclosed by
Landlord to any third party except as specifically provided in this paragraph,
unless the same becomes a part of the public domain without the fault of
Landlord.

13.8 Transfer By Landlord. Landlord and its successors in interest shall have
the right to transfer their interest in the Building, the Property, or any
portion thereof at any time and to any person or entity. In the event of any
such transfer, the Landlord originally named herein (and in the case of any
subsequent transfer, the transferor), from the date of such transfer, (i) shall
be automatically relieved, without any further act by any person or entity, of
all liability for the performance of the obligations of the Landlord hereunder
which may accrue after the date of such transfer and (ii) shall be relieved of
all liability for the performance of the obligations of the Landlord hereunder
which have accrued before the date of transfer if its transferee agrees to
assume and perform all such prior obligations of the Landlord hereunder. Tenant
shall attorn to any such transferee. After the date of any such transfer, the
term "Landlord" as used herein shall mean the transferee of such interest in the
Building or the Property.

13.9 Force Majeure. The obligations of each of the parties under this Lease
(other than the obligations to pay money) shall be temporarily excused if such
party is prevented or delayed in performing such obligations by reason of any
strikes, lockouts or labor disputes; government restrictions, regulations,
controls, action or inaction; civil commotion; or extraordinary weather, fire or
other acts of God.

13.10 Notices. Any notice required or permitted to be given under this Lease
shall be in writing and (i) personally delivered, (ii) sent by United States
mail, registered or certified mail, postage prepaid, return receipt requested,
(iii) sent by Federal Express or similar nationally recognized overnight courier
service, or (iv) transmitted by facsimile with a hard copy sent within one (1)
business day by any of the foregoing means, and in all cases addressed as

assessments, levies and other charges of any kind or nature whatsoever, general
and special, foreseen and unforeseen (including all instruments of principal and
interest required to pay any general or special assessments for public -

13.13  General Waivers.  One party's consent to or approval of any act by the
other party requiring the first party's consent or approval shall not be deemed
to waive or render unnecessary the first party's consent to or approval of any
subsequent similar act by the other party.  No waiver of any provision hereof,
or any waiver of any breach of any provision hereof, shall be effective unless
in writing and signed by the waiving party.  The receipt by Landlord of any rent
or payment with or without knowledge of the breach of any other provision hereof
shall not be deemed a waiver of any such breach.  No waiver of any provision of
this Lease shall be deemed a continuing waiver unless such waiver specifically
states so in writing and is signed by both Landlord and Tenant.  No delay or
omission in the exercise of any right or remedy accruing to either party upon
any breach by the other party under this Lease shall impair such right or remedy
or be construed as a waiver of any such breach theretofore or thereafter
occurring.  The waiver by either party of any breach of any provision of this
Lease shall not be deemed to be a waiver of any subsequent breach of the same or
any other provisions herein contained.

13.14  Miscellaneous.  Should any provisions of this Lease prove to be invalid
or illegal, such invalidity or illegality shall in no way affect, impair or
invalidate any other provisions hereof, and such remaining provisions shall
remain in full force and effect.  Time is of the essence with respect to the
performance of every provision of this Lease in which time of performance is a
factor.  Any copy of this Lease which is executed by the parties shall be deemed
an original for all purposes.  This Lease shall, subject to the provisions
regarding assignment, apply to and bind the respective heirs, successors,
executors, administrators and assigns of Landlord and Tenant.  The term "party"
shall mean Landlord or Tenant as the context implies.  If Tenant consists of
more than one person or entity, then all members of Tenant shall be jointly and
severally liable hereunder.  This Lease shall be construed and enforced in
accordance with the Laws of the State in which the Leased Premises are located.
The captions in this Lease are for convenience only and shall not be construed
in the construction or interpretation of any provision hereof.  When the context
of this Lease requires, the neuter gender includes the masculine, the feminine,
a partnership, corporation, limited liability company, joint venture, or other
form of business entity, and the singular includes the plural.  The terms
"must," "shall," "will," and "agree" are mandatory.  The term "may" is
permissive.  When a party is required to do something by this Lease, it shall do
so at its sole cost and expense without right of reimbursement from the other
party unless specific provision is made therefor.  Where Landlord's consent is
required hereunder, the consent of any Lender may also be required (as
determined by Landlord in good faith).  Landlord and Tenant shall both be deemed
to have drafted this Lease, and the rule of construction that a document is to
be construed against the drafting party shall not be employed in the
construction or interpretation of this Lease.  Where Tenant is obligated not to
perform any act or is not permitted to perform any act, Tenant is also obligated
to restrain any others reasonably within its control, including agents,
invitees, contractors, subcontractors and employees, from performing such act.

by reason of any of the provisions of this Lease.

agree that they have not had any dealings with any real estate broker(s),
leasing agent(s), finder(s) or salesmen, other than the Brokers (as named in

this Lease, and that Landlord will assume the obligation to pay Landlord's

Tenant will assume all obligations and responsibility with respect to the
payment of any broker other than Tenant's Broker that Tenant retained. Each of

entering into the Lease, which are not expressly set forth in this Lease.
Tenant further acknowledges that neither Landlord nor any of its agents made any
representations 55 to (i) whether the Leased Premises may be used for Tenant's
intended use under existing Law, or (ii) the suitability of the Leased Premises
for the conduct of Tenant's business, or (iii) the exact square footage of the
Leased Premises, and that Tenant relies solely upon its own investigations with
respect to such matters.  Tenant expressly waives any and all claims for damage
by reason of any statement, representation, warranty, promise or other agreement
of Landlord or Landlord's agent(s), if any, not contained in this Lease or in
any Exhibit attached hereto.

ARTICLE 15
OPTIONS TO EXTEND

15.1 So long as Digital Island, Inc. (or a Permitted Assignee) is the Tenant
hereunder and occupies the entirety of the Leased Premises, and subject to the
condition set forth in clause (b) below, Tenant shall have three (3) options to
extend (each an "Extension Option") the term of this Lease with respect to the
entirety of the Leased Premises, for a period of five (5) years each (each an
"Extension Period"), subject to the following conditions:

     (a) Each option to extend shall be exercised, if at all, by notice of
exercise given to Landlord by Tenant not more than fifteen months nor less than
twelve months prior to the expiration of the eleventh (11th) year of the Lease
Term or the expiration of the Extension Period then in effect, as applicable;

     (b) Anything herein to the contrary notwithstanding, if Tenant is in
default (beyond any applicable cure period) under any of the terms, covenants or
conditions of this Lease, either at the time Tenant exercises an Extension
Option or On the commencement date of the applicable Extension Period, Landlord
shall have, in addition to all of Landlord's other rights and remedies provided
in this Lease, the right to terminate such option(s) to extend upon notice to
Tenant.

                                       38
<PAGE>

15.2 1n the event the applicable Extension Option is exercised in a timely
fashion, the Lease shall be extended for the term of the applicable Extension
Period upon all of the terms and conditions of this Lease, provided that the
Base Monthly Rent for each extension period shall be the "Fair Market Rent" for
the Leased Premises, increased as set forth below.  For purposes hereof, "Fair
Market Rent" shall mean the Base Monthly Rent, that a third party tenant
executing a five (5) year lease for leased premises of similar size and with
similar quality improvements and tenant improvement allowance in Silicon Valley,
taking into account any and all tenant inducements offered in connection with
such leasing and the annual increases to Base Monthly Rent Set forth herein;
provided however, that the "Fair Market Rent" shall not take into account the
value of any alterations or improvements made to the Leased Premises by Tenant
at Tenant's sole cost and expense, which "Fair Market Rent" shall be determined
pursuant to the process described below.  At the end of the first twelve (12)
month period of any Extension Period, and at the end of each twelve (12) month
period thereafter during any Extension Period, Base Monthly Rent shall be
increased at a rate of 3.0% per annum compounded.

15.3 Within 30 days after receipt of Tenant's notice of exercise, Landlord shall
notify Tenant in writing of Landlord's estimate of the Base Monthly Rent for the
applicable Extension Period, based on the provisions of Paragraph 15.2 above.
Within 30 days after receipt of such notice from Landlord, Tenant shall have the
right either to (i) accept Landlord's statement of Base Monthly Rent as the Base
Monthly Rent for the applicable extension period; or (ii) elect to arbitrate
Landlord's estimate of Fair Market Rent, such arbitration to be conducted
pursuant to the provisions hereof Failure on the part of Tenant to require
arbitration of Fair Market Rent within such 30-day period shall constitute
acceptance of the Base Monthly Rent for the applicable Extension Period as
calculated by Landlord.  If Tenant elects arbitration, the arbitration shall be
concluded within 90 days after the date of Tenant's election, subject to
extension for an additional 30-day period if a third arbitrator is required and
does not act in a timely manner.  To the extent that arbitration has not been
completed prior to the expiration of any preceding period for which Base Monthly
Rent has been determined, Tenant shall pay Base Monthly Rent at the rate
calculated by Landlord, with the potential for an adjustment to be made once
Fair Market Rent is ultimately determined by arbitration.

15.4 In the event of arbitration, the judgment or the award rendered in any such
arbitration may be entered in any court having jurisdiction and shall be final
and binding between the parties.  The arbitration shall be conducted and
determined in the City and County of San Francisco in accordance with the then
prevailing rules of the American Arbitration Association or its successor for
arbitration of commercial disputes except to the extent that the procedures
mandated by such rules shall be modified as follows:

     (a) Tenant shall make, demand for arbitration in writing within 30 days
after service of Landlord's determination of Fair Market Rent given under
Paragraph 15.3 above, specifying therein the name and address of the person to
act as the arbitrator on its behalf. The arbitrator shall be qualified as a real
estate appraiser familiar with the Fair Market Rent of similar industrial,
research and development, or office space in the Silicon Valley area who would
qualify as an expert witness over objection to give opinion testimony addressed
to the issue in a court of competent jurisdiction. Failure on the part of Tenant
to make a proper demand in a timely manner for such arbitration shall constitute
a waiver of the right thereto. Within 15 days after the service of the demand
for arbitration, Landlord shall give notice to Tenant, specifying the name and
address of the person designated by Landlord to act as arbitrator on its behalf
who shall be similarly qualified. If Landlord fails to notify Tenant of the
appointment of its arbitrator, within or by the time above specified, then the
arbitrator appointed by Tenant shall be the arbitrator to determine the issue.

     (b) In the event that two arbitrators are chosen pursuant to Paragraph
15.4(a) above, the arbitrators so chosen shall, within 15 days after the second
arbitrator is appointed determine the Fair Market Rent. If the two arbitrators
shall be unable to agree upon a determination of Fair Market Rent within such
15-day period, they, themselves, shall appoint a third arbitrator, who shall be
a competent and impartial person with qualifications similar to those required
of the first two arbitrators pursuant to Paragraph 15.4(a). In the event they
are unable to agree upon such appointment within seven days after expiration of
such 15-day period, the third arbitrator shall be selected by the parties
themselves, if they can agree thereon, within a further period of 15 days. If
the parties do not so agree, then either party, on behalf of both, may request
appointment of such a qualified person by the then Chief Judge of the United
States District Court having jurisdiction over the County of Santa Clara, acting
in his private and not in his official capacity, and the other party shall not
raise any question as to such Judge's full power and jurisdiction to entertain
the application for and make the appointment. The three arbitrators shall decide
the dispute if it has not previously been resolved by following the procedure
set forth below.

                                       39
<PAGE>

     (c) Where an issue cannot be resolved by agreement between the two
arbitrators selected by Landlord and Tenant or settlement between the parties
during the course of arbitration, the issue shall be resolved by the three
arbitrators within 15 days of the appointment of the third arbitrator in
accordance with the following procedure. The arbitrator selected by each of the
parties shall state in writing his determination of the Fair Market Rent
supported by the reasons therefor with counterpart Copies to each party. The
arbitrators shall arrange for a simultaneous exchange of such proposed
resolutions. The role of the third arbitrator shall be to select which of the
two proposed resolutions most closely approximates his determination of Fair
Market Rent. The third arbitrator shall have no right to propose a middle ground
or any modification of either of the two proposed resolutions. The resolution he
chooses as most closely approximating his determination shall constitute the
decision of the arbitrators and be final and binding upon the parties.

     (d) In the event of a failure, refusal or inability of any arbitrator to
act, his successor shall be appointed by him, but in the case of the third
arbitrator, his successor shall be appointed in the same manner as provided for
appointment of the third arbitrator. The arbitrators shall decide the issue
within 15 days after the appointment of the third arbitrator. Any decision in
which the arbitrator appointed by Landlord and, the arbitrator appointed by
Tenant concur shall be binding and conclusive upon the parties. Each party shall
pay the fee and expenses of its respective arbitrator and both shall share the
fee and expenses of the third arbitrator, if any, and the attorneys' fees and
expenses of counsel for the respective parties and of witnesses shall be paid by
the respective party engaging such counsel or calling such witnesses.

     (e) The arbitrators shall have the right to consult experts and competent
authorities to obtain factual information or evidence pertaining to a
determination of Fair Market Rent, but any such consultation shall be made in
the presence of both parties with full right on their part to cross-examine. The
arbitrators shall render their decision and award in writing with Counterpart
copies to each party. The arbitrators shall have no power to modify the
provisions of this Lease.

ARTICLE 16

Tenant prior to commencement of the Option Period.

     (b) Digital Island, Inc. must be the Tenant hereunder and occupy the

     (c) Anything herein to the contrary notwithstanding, if Tenant is in

remedies provided in this Lease, the right to terminate the Right of First
Refusal upon notice to Tenant.

As used herein, "Option Period" shall mean the period of time commencing six (6)
months after the Lease Commencement Date, and ending thirty (30) months

Remaining Premises any third party tenant.

                                       40
<PAGE>

16.2 If at any time during the Option Period, Landlord identifies a tenant for
the Remaining Premises, then Landlord shall notify Tenant in writing and Tenant
shall have ten (10) days after receipt of Landlord's written notice to notify
Landlord in writing its election to lease the Remaining Premises.  The terms of
any leasing of the Remaining Premises by Tenant shall be on the same terms and
conditions as this Lease, including the Base Monthly Rent (on a per-square foot
basis) then in effect and the Improvement Allowance set forth in the Work Letter
(on a per square foot basis).  If Tenant timely provides Landlord with notice of
its election to lease the Remaining Premises within said ten (10) day period,
then the parties shall consummate the lease of the Remaining Premises by the
preparation and execution of an amendment to this Lease within thirty (30) days
after Landlord's receipt of Tenant's notice.  If Tenant does not indicate in
writing its election to lease such Remaining Premises within said ten (10) day
period, then Landlord shall have the right to lease the Remaining Premises to a
third party.

ARTICLE 17
TELEPHONE SERVICE

Notwithstanding any other provision of this Lease to the contrary:

     (a)  So long as the entirety of the Leased Premises is leased to Tenant:

               (i)   Landlord shall have no responsibility for providing to
Tenant any telephone equipment, including wiring, within the Leased Premises or
for providing telephone service or connections from the utility to the Leased
Premises; and

               (ii)  Landlord makes no warranty as to the quality, continuity or
availability of the telecommunications services in the Building, and Tenant
hereby waives any claim against Landlord for any actual or consequential damages
(including damages for loss of business) in the event Tenant's
telecommunications services in any way are interrupted, damaged or rendered less
effective, except to the extent caused by the grossly negligent or willful act
or omission by Landlord, its agents or employees. Tenant accepts the telephone
equipment (including, without limitation, the INC, as defined below) in its "AS-
IS" condition, and Tenant shall be solely responsible for contracting with a
reliable third party vendor to assume responsibility for the maintenance and
repair thereof (which contract shall contain provisions requiring such vendor to
inspect the INC periodically (the frequency of such inspections to be determined
by such vendor based on its experience and professional judgment), and requiring
such vendor to meet local and federal requirements for telecommunications
material and workmanship). Landlord shall not be liable to Tenant and Tenant
waives all claims against Landlord whatsoever, whether for personal injury,
property damage, loss of use of the Leased Premises, or otherwise, due to the
interruption or failure of telephone services to the Leased Premises. Tenant
hereby holds Landlord harmless and agrees to indemnify, protect and defend
Landlord from and against any liability for any damage, loss or expense due to
any failure or interruption of telephone service to the Leased Premises for any
reason.

     (b)  At such time as the entirety of the Leased Premise is no longer leased
to Tenant, Landlord shall in its sole discretion have the right, by written
notice to Tenant, to elect to assume limited responsibility for INC, as provided
below, and upon such assumption of responsibility by Landlord, this subparagraph
(b) shall apply prospectively.

               (i)  Landlord shall provide Tenant access to such quantity of
pairs in the Building intra-building network cable ("INC") as is determined to
be available by Landlord in its reasonable discretion. Tenant's access to the
INC shall be solely by arrangements made by Tenant, as Tenant may elect,
directly with Pacific Bell or Landlord (or such vendor as Landlord may
designate), and Tenant shall pay all reasonable charges as may be imposed in
connection therewith. Pacific Bell's charges shall be deemed to be reasonable.
Subject to the foregoing, Landlord shall have no responsibility for providing to
Tenant any telephone equipment, including wiring, within the Leased Premises or
for providing telephone service or connections from the utility to the Leased
Premises, except as required by law.

               (ii) Tenant may alter, modify, add to or disturb any telephone
wiring in the Leased Premises upon notice to Landlord. Tenant shall be liable to
Landlord for any damage to the telephone wiring in the Building due to the act,
negligent or otherwise, of Tenant or any employee, contractor or other agent of
Tenant. Tenant shall have no access to the telephone closets within the
Building, except in the manner and under reasonable procedures

                                       41

established by Landlord. Tenant shall promptly notify Landlord of any actual or
suspected failure of telephone service to the Leased Premises.

               (iii)     All costs incurred by Landlord for the installation,
maintenance, repair and replacement of telephone wiring in the Building shall be
a Property Maintenance Cost.

               (iv)      Landlord makes no warranty as to the quality,
continuity or availability of the telecommunications services in the Building,
and Tenant hereby waives any claim against Landlord for any actual or
consequential damages (including damages for loss of business) in the event
Tenant's telecommunications services in any way are interrupted, damaged or
rendered less effective, except to the extent caused by the grossly negligent or
willful act or omission by Landlord, its agents or employees. Tenant
acknowledges that Landlord meets its duty of care to Tenant with respect to the
Building INC by contracting with a reliable third party vendor to assume
responsibility for the maintenance and repair thereof (which contract shall
contain provisions requiring such vendor to inspect the INC periodically (the
frequency of such inspections to be determined by such vendor based on its
experience and professional judgment), and requiring such vendor to meet local
and federal requirements for telecommunications material and workmanship).
Subject to the foregoing, Landlord shall not be liable to Tenant and Tenant
waives all claims against Landlord whatsoever, whether for personal injury,
property damage, loss of use of the Leased Premises, or otherwise, due to the
interruption or failure of telephone services to the Leased Premises. Tenant
hereby holds Landlord harmless and agrees to indemnify, protect and defend
Landlord from and against any liability for any damage, loss or expense due to
any failure or interruption of telephone service to the Leased Premises for any
reason. Tenant agrees to obtain loss of rental insurance adequate to cover any
damage, loss or expense occasioned by the interruption of telephone service.
