                                    SUBLEASE

    Sublease dated the 17th day of January 2002 by and between HYPERION

Delaware corporation having an address at 2121 S. El Camino Real #400, San
Mateo, CA, 94403.

                                    RECITALS:

    A. By lease dated December 15, 1999, as amended by First Amendment to Lease
dated August 21, 2000 and as further amended by Second Amendment to Lease dated
October 25, 2000 (collectively referred to herein as the "Prime Lease"),
Sublandlord, as tenant, leased from EOP-Metro Center, L.L.C. as successor in
interest to Spieker Properties, Inc., as landlord ("Landlord"), premises (the
"Prime Premises") consisting of approximately 42,807 rentable square feet on the
4th, 5th and 8th floors of a building known as 950 Tower Lane, Foster City,
California. Sublandlord and Landlord also entered into a Parking License
Agreement dated January 5, 2000 (the "Parking License Agreement").

    B. Subtenant desires to sublease from Sublandlord a portion of the Prime
Premises, which portion consists of approximately 21,415 rentable square feet on
the 5th floor (the "Premises"), and Subtenant desires to sublicense all parking
allocated to the Premises under the Parking License Agreement. Sublandlord
desires to sublease the Premises and sublicense the parking rights appurtenant
thereto to Subtenant on the terms and subject to the conditions hereinafter set
forth.

    C. All defined terms used but not defined in this Sublease shall have the
same meanings given in the Prime Lease.

    NOW, THEREFORE, for and in consideration of the mutual covenants hereinafter
contained, the parties hereby agree as follows:

1.      Demise; Use.

        (a) Sublandlord hereby subleases the Premises and sublicenses all
parking appurtenant thereto to Subtenant. Sublandlord represents that the Prime
Lease and the Parking License Agreement are in full force and effect; that
Sublandlord is not in default under the Prime Lease or the Parking License
Agreement; and that, to its best knowledge, Landlord is not in default under the
Prime Lease or the Parking License. A copy of the Prime Lease is attached hereto
as Exhibit A and a copy of the Parking License Agreement is attached hereto as
Exhibit B.

        (b) The Premises shall be used and occupied only for the Permitted Use
set forth in the Prime Lease and for no other purpose.

2.      Term; As-Is Condition.

        (a) The term (the "Term") of this Sublease shall commence on February 1,
2002 (the "Commencement Date") and shall terminate on September 30, 2008, unless
sooner terminated pursuant to the provisions of this Sublease (the "Termination
Date"). Notwithstanding the foregoing, if for any reason Sublandlord cannot
deliver possession of the Premises to Subtenant on the Commencement Date,
Sublandlord shall not be subject to any liability therefore, nor shall such
failure affect the validity of this Sublease or the obligations of Subtenant
hereunder or extend the term hereof, but in such case Subtenant shall not be
obligated to pay rent until thirty (30) days after possession of the Premises is
tendered to Subtenant; provided, however, that if Sublandlord shall not have
delivered possession of the Premises within sixty (60) days from the
Commencement Date, Subtenant may, at Subtenant 's option, by notice in writing
to Sublandlord within ten (10) days thereafter, cancel this Sublease, in which
event the parties shall be discharged from all obligations hereunder and all
funds paid to Sublandlord by Subtenant on account of this Sublease shall be
immediately refunded to Subtenant. If Subtenant occupies the Premises prior to
the Commencement Date, such occupancy shall be subject to all of the provisions
hereof and such occupancy shall not advance the Termination Date.

<PAGE>
        (b) Subtenant shall take possession of the Premises in its "as is"
condition as of the date of the execution hereof, subject to all applicable
zoning, municipal, county and state laws, ordinances, and regulations governing
and regulating the use of the Premises, and accepts this Sublease subject
thereto and to all matters disclosed thereby and by any exhibits attached
hereto. No representations or warranties have been made to Subtenant as to the
suitability of the Premises for the conduct of Subtenant's business, nor any
representations concerning the condition of the Premises, nor have any promises
to alter or improve the Premises (or to give any form of work allowance) been
made by Sublandlord or any party on behalf of Sublandlord, provided, however,
that Sublandlord represents that the HVAC system, electrical, plumbing and
lighting systems within the Premises are in good working order.

3.      Incorporation By Reference.

The terms, provisions, covenants, and conditions of the Prime Lease are hereby
incorporated by reference on the following basis: Subtenant hereby assumes all
of the obligations of Sublandlord under the Prime Lease with respect to the
Premises, accruing or payable during the Term. Notwithstanding the foregoing,
the following provisions of the Prime Lease are hereby excluded from
incorporation into the Sublease: Basic Lease Information save and except Project
and Building Descriptions, Permitted Use and Occupancy and Parking Densities;
Sections 2, 21(B), 28, 40-45; Exhibits B-1, B-3, D-1, D-2 & D-3; and all
provisions of the First and Second Amendments to Lease save and except
provisions regarding extension of the term of the Prime Lease. To the extent
there are inconsistencies in the terms of the Prime Lease and this Sublease, the
terms of this Sublease shall control. The term "Landlord" in the Prime Lease
shall refer to Sublandlord hereunder, its successors and assigns; and the term
"Tenant" therein shall refer to Subtenant hereunder, its permitted successors
and assigns. The obligations assumed by Subtenant hereunder which accrue during
the Term shall survive and extend beyond the termination of this Sublease.

</TABLE>

Monthly installments shall be due and payable on the first (1st) day of each
month, commencing on the date which is thirty (30) days after the Commencement
Date (the "Rent Commencement Date"), prorated for a portion of a month. An
amount equal to one monthly installment of Base Rent has been paid upon
Subtenant's execution hereof, which shall be applied to the first installment of
Base Rent due hereunder. All other payments owed by Subtenant hereunder shall be
paid as Additional Rent. Base Rent and Additional Rent are herein collectively
called "Rent".

        (b) Rent shall be paid without deduction or setoff, and Base Rent shall
be paid without notice or demand. If any Rent shall not be paid on or before the
fifth (5th) day after the due date thereof, Subtenant shall, in addition
thereto, pay a late charge of 5% of the overdue installment.

5.      Escalations and Electrical Charges.

        (a) Pursuant to Section 7 of the Prime Lease, Sublandlord is obligated
to pay amounts to cover increases in the Operating Expenses of Landlord.
Subtenant shall pay to Sublandlord the increases in Tenant's Proportionate Share
of Operating Expenses ("Escalations") imposed by Landlord that are allocable to
the Premises in accordance with the Prime Lease, over and above the Operating
Expenses for the year ending

<PAGE>
December 31, 2002 (the "Base Year"). Tenant's Proportionate Share of Operating
Expenses attributable to the Premises for the Base Year have been estimated by
Landlord to be $14.40 per square foot, which Operating Expenses are included in
the Base Rent payable hereunder during calendar year 2002. Sublandlord shall
provide copies of all invoices and notices from Landlord to Sublandlord
attributable to the Premises, including without limitation Landlord's statement
delivered pursuant to Section 7(C) of the Prime Lease, which statement shall be
accompanied by Sublandlord's estimate of Subtenant's proportional share of any
Escalations over the Base Year and subsequent years during the Term. The
Premises represent 50.03% ("Subtenant's Proportionate Share") of the Prime
Premises. Sublandlord agrees to provide written notice to Subtenant of any
change in the size of the Prime Premises, including a revised figure for
Subtenant's Proportionate Share. In no event shall Subtenant pay in excess of
Subtenant's Proportionate Share of the Escalations. Subtenant shall not pay any
Escalations based upon disproportionate allocations of Operating Expenses by
Landlord to any portion of the Prime Premises which are not included within the
Premises and which result from Sublandlord or any other occupant's particular
use and occupancy of such space.

        (b) Pursuant to Section 15 of the Prime Lease, Sublandlord is obligated
to pay Landlord for the use of certain after hours utilities and services.
Subtenant shall pay, either directly to Landlord, or shall reimburse Sublandlord
for such costs should same be paid by Sublandlord on behalf of Subtenant, for
any costs associated with such after hours utilities or services utilized by
Subtenant. Furthermore, Subtenant shall also be responsible to pay Landlord
directly, or shall reimburse Sublandlord for such costs should same be paid for
by Sublandlord on behalf of Subtenant, for any other services requested by
Subtenant that Sublandlord would be required to pay for under the Prime Lease
with respect to the Premises, including without limitation, any construction or
repair work, overtime HVAC or electric (including that related to any
supplemental HVAC units located within the Premises) or additional janitorial
services. Notwithstanding the foregoing, Subtenant shall not be required to pay
for any such additional utilities or services attributable to Sublandlord's or
any other occupant's use and occupancy of any portion of the Prime Premises not
included within the Premises.

        (c) The amounts required to be paid by Subtenant to Sublandlord under
this Section shall be paid within ten (10) days after Sublandlord shall render a
statement therefor. Sublandlord's statement shall be accompanied by copies of
any relevant statements or bills received from Landlord.

<PAGE>
6.      Subletting and Assignment.

Except as provided in Section 21(A)(3) of the Prime Lease, Subtenant shall not,
without the prior written consent of Sublandlord (a) further sublet all or any
part of the Premises; (b) transfer, hypothecate, assign, convey, or mortgage
this Sublease or any interest under it or allow any lien upon Subtenant's
interest hereunder by operation of law; or (c) suffer, tolerate, permit, or
allow the use or occupancy of the Premises by anyone other than Subtenant, its
agents and employees. Sublandlord shall not unreasonably withhold its consent to
a further subletting of the Premises or an assignment of this Sublease by
Subtenant. Sublandlord's consent to any such subletting or assignment, however,
shall be conditional upon and subject to Subtenant complying with all of the
provisions of Section 21 of the Prime Lease and obtaining the written consent of
Landlord thereto. Any rent or other consideration realized by Subtenant under
any such sublease or assignment in excess of the Rent payable hereunder, after
payment by Subtenant of all reasonable costs associated with such transaction,
shall be divided and paid fifty percent (50%) to Subtenant and fifty percent
(50%) to Sublandlord. No such transaction shall release Subtenant from liability
hereunder. Notwithstanding anything in the Prime Lease to the contrary, should
Subtenant desire to assign or sublet 50% or more of the Premises, Sublandlord
shall have the right to terminate this Sublease with respect to the space so
affected as of the date so requested by Subtenant.

7.      Insurance Compliance.

Subtenant shall maintain, at its sole cost and expense, for the Term, general
public liability insurance (naming Sublandlord, Landlord and designees of
Landlord as additional insureds) against claims for personal injury, death, or
property damage occurring upon, in, about, or adjacent to the Premises, such
insurance to afford protection with combined coverage of at least $3,000,000
with respect to personal injury, death and property damage. Subtenant shall also
maintain, at its sole expense, for the Term, any and all insurance in the
amounts and form required of Sublandlord by and pursuant to the provisions of
the Prime Lease with respect to the Premises. All such policies shall be issued
by reputable insurance companies meeting the requirements of Section 8(B)(4) of
the Prime Lease and shall be endorsed to provide that they shall not be modified
or cancelled without 30 days' prior written notice to Sublandlord and Landlord.
On or prior to the Commencement Date, Subtenant shall furnish certificates to
Sublandlord evidencing that the required coverage is being maintained, together
with such evidence as Sublandlord shall reasonably deem satisfactory of the
payment of premiums thereon. Notwithstanding anything in this Section 7 to the
contrary, although Subtenant is required to insure the Additional Systems (as
defined in Section 21 hereof) located within the Premises as of the Commencement
Date for "full replacement value" in accordance with the provisions of Section
8(B)(1) of the Prime Lease, Subtenant shall not be required to insure the
Additional Systems for an amount in excess of TWO MILLION ONE HUNDRED FORTY ONE
THOUSAND FIVE HUNDRED AND 00/100 DOLLARS ($2,141,500.00), and in the event of
any casualty which does not result in the termination of this Sublease,
Subtenant shall not be required to spend in excess of $2,141,500 in connection
with restoration of the Additional Systems located within the Premises as of the
Commencement Date.

8.      Indemnification.

        (a) Except to the extent caused by the negligence or willful misconduct
of Sublandlord, Sublandlord, its officers, agents, and employees, shall not be
liable for, and Subtenant shall indemnify and save Sublandlord harmless from and
against any and all claims, liability, loss, or damage during the Term to
persons or property sustained by Subtenant or by any other person, due to the
Premises or any part thereof or any appurtenances thereof becoming out of
repair, or due to the happening of any accident in, on, or about the Premises or
the Project, or any damage caused by fire, or other casualty or leakage, or due
to the act or neglect of any person, including, but not limited to, the
employees, agents, or contractors of Sublandlord or Landlord. This provision
shall apply (but not exclusively) to damage caused by sprinkling devices or air
conditioning or heating equipment and to damage caused by water, wind, frost,
steam, excessive heat or cold, broken glass, gas, odors, or noise or by the
bursting or leaking of pipes or plumbing fixtures or the failure of any
appurtenances or equipment. Sublandlord and Subtenant waive all rights against
each other for damages caused by fire or other perils covered by insurance in
connection with the Premises, to the extent of insurance received.

        (b) Subtenant shall not take any action or fail to take any action in
connection with the Premises, the Building or the Project as a result of which
Sublandlord would be in violation of any of the provisions of the Prime Lease or
the Parking License Agreement. Sublandlord shall not take any action or fail to
take any action

<PAGE>
in connection with the Prime Premises, the Building or the Project as a result
of which Sublandlord would be in violation of any of the provisions of the Prime
Lease or the Parking License Agreement. Subtenant hereby agrees to defend,
indemnify, and hold Sublandlord harmless from and against all loss, cost,
liability, damage, and expense (including, but not limited to, attorneys' fees
and court costs) caused by or arising out of Subtenant's act or inaction as a
result of which Sublandlord is alleged and/or determined to be in violation of
any of the provisions of the Prime Lease or the Parking License Agreement.
Sublandlord hereby agrees to defend, indemnify, and hold Subtenant harmless from
and against all loss, cost, liability, damage, and expense (including, but not
limited to, attorneys' fees and court costs) caused by or arising out of
Sublandlord's act or inaction as a result of which Sublandlord is alleged and/or
determined to be in violation of any of the provisions of the Prime Lease or the
Parking License Agreement.

9.      Casualty.

If the Premises are damaged by fire or other casualty, and Landlord or
Sublandlord shall, pursuant to the terms of the Prime Lease, elect to terminate
the Prime Lease, this Sublease shall cease and terminate on the date of
termination of the Prime Lease, and Rent shall be apportioned from the time of
the damage. Otherwise, this Sublease shall remain in full force and effect
subject to the terms of the Prime Lease. Sublandlord shall have no obligation
hereunder to repair any portion of the Building, the Project or the Premises,
including, without limitation, the Alterations and Additional Systems (as
defined in Section 21 hereof), whether or not this Sublease shall be terminated,
it being expressly understood that Subtenant shall be responsible for any
restoration in excess of Landlord's repair obligations under the Prime Lease.

10.     Rights of Landlord.

        (a) Subtenant acknowledges any rights specifically reserved by Landlord
under the Prime Lease, and Subtenant further acknowledges that its possession
and use of the Premises shall at all times be subject to such rights. Subtenant
hereby releases Sublandlord from all liability in connection with Landlord's
exercise of such rights.

        (b) If Subtenant fails to do any act required of it hereunder or under
the Prime Lease, Sublandlord may (but shall not be obligated to), after ten
days' written notice to Subtenant to cure the default and failure of Subtenant
to cure the same within such period (or, if such cure would require more than
ten days, Subtenant fails to either commence to cure the same within such ten
day period or to diligently pursue same to completion), or at any time without
notice in event of emergency, perform the same for the account of Subtenant. As
used herein, "emergency" means any circumstance which, in Sublandlord's
reasonable judgment, if not addressed immediately, may cause substantial injury
to persons or damage to property. If Sublandlord makes any expenditures or
incurs any obligations in connection with a default by Subtenant, including, but
not limited to, reasonable attorneys' fees and costs in instituting, prosecuting
or defending any action or proceeding against Subtenant, such reasonable and
actual sums paid or obligations incurred shall be paid by Subtenant to
Sublandlord within ten days of rendition of any statement to subtenant
hereunder.

<PAGE>
11.     Default by Landlord.

Sublandlord shall not be liable to Subtenant for Landlord's failure to perform
any of Landlord's obligations under the Prime Lease, nor shall Sublandlord have
any obligation to perform same or to bring legal proceedings or take any other
action against Landlord to assure performance of Landlord's obligations under
the Prime Lease. Notwithstanding the foregoing, Sublandlord agrees, at
Subtenant's cost and expense, to exercise reasonable efforts to enforce its
rights against Landlord under the Prime Lease after Subtenant's request. Except
as otherwise provided herein, whenever Sublandlord shall have the right to
enforce any rights against Landlord or any other party under the Prime Lease
because of the default or breach of Landlord or such other party with respect to
the Premises, and if, within a reasonable period after Subtenant's request,
Sublandlord fails to enforce such rights, then Subtenant shall have the right,
in the name of Subtenant or, if necessary, in the name of Sublandlord, to
enforce any such rights of Sublandlord with respect to the Premises. Such
enforcement shall be at the sole expense of Subtenant, and Subtenant shall
indemnify Sublandlord against all costs and expenses, including but not limited
to reasonably attorneys' fees, which may be incurred by Sublandlord in
connection with any claim, action, or proceeding so undertaken by Subtenant. Any
amount of recovery obtained by Subtenant shall be the property of Subtenant,
except that Sublandlord shall be compensated therefrom for any damages sustained
by Sublandlord as a consequence of such default or breach on the part of
Landlord or such other party.

12.     Broker.

The parties acknowledge that this Sublease was procured through the efforts of
Cornish & Carey Commercial and Sublandlord shall compensate such broker pursuant
to separate agreement. Subtenant represents and warrants that it dealt with no
other broker in connection with this Sublease and shall hold Sublandlord
harmless from any liability or loss, including reasonable attorneys' fees, to
any broker or salesman (other than as aforesaid) claiming a commission as a
result of having interested Subtenant in the Premises. Sublandlord represents
and warrants that it dealt with no other broker in connection with this Sublease
and shall hold Subtenant harmless from any liability or loss, including
reasonable attorneys' fees, to any broker or salesman (other than as aforesaid)
claiming a commission as a result of a breach of said representation and
warranty.

13.     Taxes.

Subtenant shall pay any taxes or fees imposed by any governmental authority upon
or as the result of this Sublease or the transfer of any property or interests
in property hereunder, except that Subtenant shall not be liable for any
federal, state, or municipal income tax imposed upon Sublandlord as a result of
this Sublease or any profits derived hereunder.

14.     Remedies; Security Deposit.

        (a) The taking of any action by Subtenant, the occurrence of any event
in regard to Subtenant, or the failure to act by Subtenant which would be a
default under the Prime Lease if taken by Sublandlord or if occurring or failing
to occur in regard to Sublandlord, shall entitle Sublandlord to take all action
with regard to Subtenant under this Sublease which Landlord is permitted to take
against Sublandlord under the terms of the Prime Lease. Subtenant hereby
indemnifies and holds Sublandlord harmless from and against all loss, cost,
injury, liability, or expense (including reasonable attorneys' fees and court
costs) caused by or arising out of Subtenant's default, breach, or violation of
the terms of this Sublease.

        (b) On or before the execution of this Sublease, as a security deposit
to assure the faithful performance by Subtenant of all of the obligations
assumed by it hereunder, Subtenant shall deliver to Sublandlord an unconditional
irrevocable letter of credit in the amount of ONE HUNDRED SEVENTY SIX THOUSAND
SIX HUNDRED AND SEVENTY THREE DOLLARS AND SEVENTY FIVE CENTS ($176,673.75) and
in a form reasonably satisfactory to Sublandlord drawn on or issued by a bank
reasonably acceptable to Sublandlord (the "Letter of Credit"). The Letter of
Credit shall either (a) expire no earlier than 60 days following the Termination
Date (the "LC Date"), (b) be automatically renewing until the LC Date or, (c) if
the Letter of Credit shall not be automatically renewing through the LC Date or
expires prior to the LC Date, said Letter of Credit shall expire no earlier than
September 30, 2003 and shall provide that if it is not replaced by a replacement
letter of credit issued by a bank reasonably satisfactory to Sublandlord on or
before thirty (30) days prior to the expiration date, Sublandlord may draw down
the balance of the Letter of Credit and hold and

<PAGE>
apply same for the purposes set forth herein. The Letter of Credit (or any
subsequent cash deposit held hereunder) shall also be referred to herein as the
"Deposit". If Subtenant defaults with respect to any of provision of this
Sublease, including the payment of Rent, Sublandlord may apply all or any part
of the Deposit to the extent necessary for the payment of any Rent, or to
compensate Sublandlord for any other loss, cost or damage which Sublandlord may
suffer by reason of Subtenant's default. Should part or all of the Deposit be
applied by Sublandlord for the payment of overdue Rent or other obligations of
Subtenant hereunder, then Subtenant shall, within 10 days after the written
demand of Sublandlord, deliver to Sublandlord a replacement letter of credit or
an additional letter of credit, in form and substance reasonably satisfactory
to, and issued by a bank reasonably satisfactory to Sublandlord in the amount
necessary to replace the Letter of Credit to its original amount (or if the
Letter of Credit has been reduced to a "cash" deposit, deliver to Sublandlord
sufficient funds to restore the Deposit to its original amount). Subtenant's
failure to do so shall constitute a default hereunder. If Subtenant performs all
of Subtenant's obligations hereunder, the Deposit, or so much thereof as has not
theretofore been applied by Sublandlord, shall be returned to Subtenant (or at
Sublandlord's option, to the last assignee, if any, of Subtenant's interest
hereunder) within 60 days of the Termination Date, and after Subtenant has
vacated the Premises.

        (c) Subtenant acknowledges that the security deposit paid by Sublandlord
to Landlord pursuant to the terms of the Prime Lease is the property of
Sublandlord and that Subtenant has no claim or right to any portion of such
security deposit.

15.     Interest.

Any Rent not paid within 30 days after the due date thereof shall thereafter be
payable with interest at the rate of four percentage points per annum plus the
fluctuating prime or base rate of Fleet Bank (or any successor) in effect on the
due date of such rent, which interest shall be payable for the period from the
due date to the date of payment; provided, however, that any interest charged
hereunder shall not exceed the maximum amount of interest allowed under
California law.

16.     Option to Extend.

Anything in the Prime Lease to the contrary notwithstanding, Subtenant shall
have no option to extend or renew the Term of this Sublease or to expand the
Premises.

17.     Surrender and Holdover.

        (a) Upon any termination of this Sublease, by expiration of the Term or
otherwise:

        (i)     Subtenant shall immediately vacate the Premises and surrender
                possession thereof to Sublandlord in substantially the same
                condition as delivered to Subtenant on the Commencement Date,
                reasonable wear and tear excepted (and, only in the case where
                the Prime Lease and Sublease are both terminated due to a
                casualty, damage by casualty excepted), and subject to any
                request by Sublandlord or Landlord to leave certain Alterations
                installed by Subtenant in the Premises;

        (ii)    Subtenant shall surrender the Premises free and clear of all
                liens and encumbrances; and

        (iii)   Sublandlord shall have full authority and license to enter the
                Premises and take possession of same.

    (b) Subtenant shall pay to Sublandlord 200% of the monthly Rent hereunder
plus all other costs for each month or portion thereof that Subtenant shall
retain possession of the Premises or any part thereof after the termination of
this Sublease without Sublandlord's consent, whether by lapse of time or
otherwise, and shall also pay all damages sustained by Sublandlord to Landlord
or otherwise on account thereof. Furthermore, Subtenant shall be subject to
eviction proceedings and any other remedy or right accorded to Sublandlord in
law or at equity. Any holding over by Subtenant upon termination of this
Sublease shall not be evidence of an extension or renewal of the Term hereof,
nor shall acceptance of Rent or other payments by Sublandlord from Subtenant be
evidence of the same, but shall be on a month to month basis, terminable by
either party on 30 days' notice.

18.     Attorneys' Fees.

<PAGE>
If any party named herein brings an action to enforce the terms hereof or to
declare rights hereunder, the prevailing party in any such action, on trial and
appeal, shall be entitled to reasonable attorneys' fees and court costs to be
paid by the losing party as fixed by the Court.

19.     Miscellaneous.

        (a) Each provision of this Sublease shall extend to and shall bind and
inure to the benefit of Sublandlord and Subtenant and their respective permitted
successors and assigns, and shall be construed in accordance with the laws of
the State of California.

        (b) Subtenant acknowledges that this Sublease is subordinate to the
Prime Lease. In the event of any conflict between the terms and conditions of
this Sublease and the terms and conditions of the Prime Lease, the terms and
conditions of this Sublease shall control.

        (c) In the event that any provision of this Sublease is deemed to be
invalid or unenforceable for any reason, this Sublease shall be construed as not
containing such provision, and the invalidity or unenforceability thereof shall
not render any other provision of this Sublease invalid or unenforceable.

        (d) Any provision of this Sublease or the Prime Lease which requires
Sublandlord not to unreasonably withhold its consent shall never be the basis
for an award of damages or give rise to a right of setoff to Subtenant, but may
be the basis for a declaratory judgment or specific injunction with respect to
the matter in question.

        (e) Whenever Subtenant must obtain the consent of Landlord with respect
to the Premises, Sublandlord shall cooperate with Subtenant (at Subtenant's sole
cost and expense) in obtaining Landlord's consent. Sublandlord shall promptly
forward to Subtenant true copies of all notices, requests, demands and
communications received by Sublandlord from Landlord (or its agent) with respect
to the Premises. If Subtenant shall not give timely directions to Sublandlord,
Sublandlord may give such notice to Landlord as Sublandlord desires, or no
notice or direction with respect to the matter in question.

        (f) This Sublease may be executed in counterparts, each of which shall
constitute an original and all of which together shall constitute one and the
same agreement.

        (g) All notices shall be in writing, mailed certified mail, return
receipt requested, postage prepaid, or sent by recognized overnight courier such

cause all such maintenance to the Additional Systems to be performed and
Subtenant shall reimburse Sublandlord for the reasonable cost thereof.

                                     LEASE

THIS LEASE is made as of the 15th day of December, 1999 by and between Spieker
Properties, L.P., a California limited partnership (hereinafter called
"LANDLORD"), and Hyperion Solutions Corporation, a Delaware corporation
(hereinafter called "TENANT")

                                  1.  PREMISES

     Landlord leases to Tenant and Tenant leases from Landlord, upon the terms
and conditions hereinafter set forth, those premises (the "PREMISES") outlines
in red on EXHIBIT B1-B3 and described in the Basic Lease Information. The
Premises shall be all or part of a building (the "BUILDING") and of a project
(the "PROJECT"), which may consist of more than one building and additional
facilities, as described in the Basic Lease Information. The Building and
Project are outlined by blue and green respectively on EXHIBIT B4. Landlord and
Tenant acknowledge that physical changes may occur from time to time in the
Premises, Building or Project, and that the number of buildings and additional
facilities which constitute the Project may change from time to time, which may
result in an adjustment in Tenant's Proportionate Share, as defined in the
Basic Lease Information, as provided in Paragraph 7.A.

                     2.  POSSESSION AND LEASE COMMENCEMENT

A.  EXISTING IMPROVEMENTS. If this Lease pertains to a Premises in which the
interior improvements have already been constructed ("EXISTING IMPROVEMENTS"),
the provisions of this Paragraph 2.A. shall apply and the term commencement date
("TERM COMMENCEMENT DATE") shall be the earlier of the date on which: (1) Tenant
takes possession of some or all of the Premises; or (2) Landlord notifies Tenant
that Tenant may occupy the Premises. If for any reason Landlord cannot deliver
possession of the Premises to Tenant on the scheduled Term Commencement Date,
Landlord shall not be subject to any liability therefor, nor shall Landlord be
in default hereunder nor shall such failure affect the validity of this Lease,
and Tenant agrees to accept possession of the Premises at such time as Landlord
is able to deliver the same, which date shall then be deemed the Term
Commencement Date. Tenant shall not be liable for any Rent (defined below) for
any period prior to the Term Commencement Date. Tenant acknowledges that Tenant
has inspected and accepts the Premises in their present condition, "as is," and
as suitable for, the Permitted Use (as defined below), and for Tenant's intended
operations in the Premises. Tenant agrees that the Premises and other
improvements are in good and satisfactory condition as of when possession was
taken. Tenant further acknowledges that no representations as to the condition
or repair of the Premises nor promises to alter, remodel or improve the Premises
have been made by Landlord or any agents of Landlord unless such are expressly
set forth in this Lease. Upon Landlord's request, Tenant shall promptly execute
and return to Landlord a "Start-Up Letter" in which Tenant shall agree, among
other things, to acceptance of the Premises and to the determination of the Term
Commencement Date, in accordance with the terms of this Lease, but Tenant's
failure or refusal to do so shall not negate Tenant's acceptance of the Premises
or affect determination of the Term Commencement Date.

B.  CONSTRUCTION OF IMPROVEMENTS. If this Lease pertains to a Building to be
constructed or improvements to be constructed within a Building, the provisions
of this Paragraph 2.B. shall apply in lieu of the provisions of Paragraph 2.A.
above and the term commencement date ("TERM COMMENCEMENT DATE") shall be thirty
(30) days after delivery of the fifth floor portion of the Premises (Suite 500)
to Tenant ??? being acknowledged by Landlord and Tenant that Tenant is
currently in possession of the fourth floor portion of the Premises (Suite 400)
and the eighth floor portion of the Premises (Suite 860) under Tenant's Lease
dated March 15, 1995, as amended by Lease Amendment dated September 21, 1998
and by Lease Amendment Number Two of even date herewith (as amended, the
"EXISTING LEASE"). If for any reason Landlord cannot deliver possession of the
Premises to Tenant on the scheduled Term Commencement Date, Landlord shall not
be subject to any liability therefor, nor shall Landlord be in default
hereunder nor shall such failure affect the validity of this Lease, and Tenant
agrees to accept possession of the Premises at such time as Landlord delivers
to Tenant possession of the fifth floor portion of the Premises, which date
shall then be deemed the Term Commencement Date. Tenant shall not be liable for
any Rent for any period prior to the Term Commencement Date (but without
affecting any obligations of Tenant under any improvement agreement appended to
this Lease). In the event of any dispute as to substantial completion of work
performed or required to be performed by Landlord, the certificate of
Landlord's architect or general contractor shall be conclusive. Substantial
completion shall have occurred notwithstanding Tenant's submission of a
punchlist to Landlord, which Tenant shall submit, if at all, within three (3)
business days after the Term Commencement Date or otherwise in accordance with
any improvement agreement appended to this Lease. Upon Landlord's request,
Tenant shall promptly execute and return to Landlord a "Start-Up Letter" in
which Tenant shall agree, among other things, to acceptance of the Premises and
to the determination of the Term Commencement date, in accordance with the
terms of this Lease, but Tenant's failure or refusal to do so shall not negate
Tenant's acceptance of the Premises or affect determination of the term
Commencement Date.

                                    3.  TERM

     The term of this Lease (the "TERM") shall commence on the Term
Commencement Date and continue in full force and effect for the number of
months specified as the Length of Term in the Basic Lease Information or until
this Lease is terminated as otherwise provided herein. If the Term Commencement
Date is a date other than the first day of the calendar month, the Term shall
be the number of months of the Length of Term in addition to the remainder of
the calendar month following the Term Commencement Date.

                                    4.  USE

A.        GENERAL. Tenant shall use the premises for the permitted use specified
in the Basic Lease Information ("PERMITTED USE") and for no other use or
purpose. Tenant shall control Tenant's employees, agents, customers, visitors,
invitees, licensees, contractors, assignees and subtenants (collectively,
"TENANT'S PARTIES") in such a manner that the Tenant and Tenant's Parties
cumulatively do not exceed the occupant density (the "OCCUPANCY DENSITY") or the
parking density (the "PARKING DENSITY") specified in the Basic Lease Information
at any time. Tenant shall pay the Parking Charge specified in the Basic Lease
Information as Additional Rent (as hereinafter defined) hereunder. So long as
Tenant and/or Tenant's parties is/are occupying the Premises, Tenant and
tenant's Parties shall have the nonexclusive right to use, in common with other
parties occupying the Building or Project, the parking areas, driveways and
other common areas of the Building and Project, subject to the terms of this
Lease and such rules and regulations as Landlord may from time to time
prescribe. Landlord reserves the right, without notice or liability to Tenant,
and without the same constituting an actual or constructive eviction, to alter
or modify the common areas from time to time, including the location and
configuration thereof, and the amenities and facilities which Landlord may
determine to provide from time to time, so long as such alteration or
modification does
<PAGE>
not have a material adverse affect or cause a material decrease in the
Building's amenities or common areas which exist as of the Term Commencement
Date.

B.  LIMITATIONS. Tenant shall not permit any odors, smoke, dust, gas,
substances, noise or vibrations to emanate from the Premises or from any portion
of the common areas as a result of Tenant's or any Tenant's Party's use thereof,
nor take any action which would constitute a nuisance or would disturb, obstruct
or endanger any other tenants or occupants of the Building or Project of
elsewhere, or interfere with their use of their respective premises or common
areas. Storage outside the Premises of materials, vehicles or any other items is
prohibited. Tenant shall not use or allow the Premises to be used for any
immoral, improper or unlawful purpose, nor shall Tenant cause or maintain or
permit any nuisance in, on or about the Premises. Tenant shall not commit or
suffer the commission of any waste in, on or about the Premises. Tenant shall
not allow any sale by auction upon the Premises, or place any loads upon the
floors, walls or ceilings which could endanger the structure, or place any
harmful substances in the drainage system of the Building or project. No waste
materials or refuse shall be dumped upon or permitted to remain outside the
Premises. Landlord shall not be responsible to Tenant for the non-compliance by
any other tenant or occupant of the Building or Project with any of the
above-referenced rule or any other terms or provisions of such tenants's or
occupant's lease or other contract.

C.  COMPLIANCE WITH REGULATIONS. By entering the Premises, Tenant accepts the
Premises in the condition existing as of the date of such entry. Tenant shall
at its sole cost and expense strictly comply with all existing or future
applicable municipal, state and federal and other governmental statutes, rules,
requirements, regulations, laws and ordinances, including zoning ordinances and
regulations, and covenants, easements and restrictions of record governing and
relating to the use, occupancy or possession of the Premises, to Tenant's use
of the common areas, or to the use, storage, generation or disposal of
Hazardous Materials (hereinafter defined) (collectively "REGULATIONS"). To the
extent that the Regulations require that improvements and alterations be made
to the Premises, the Building or the Common Areas in order to cause same to
comply with the Regulations and such improvements and alterations are not
Tenant's responsibility. Landlord may treat costs of such compliance with
respect to the Premises, the Building and Common Areas as an Operating Expense
as provided under Paragraph 7.A. Tenant shall at its sole cost and expense
obtain any and all licenses or permits necessary for Tenant's use of the
Premises. Tenant shall at its sole cost and expense promptly comply with the
requirements of any board of fire underwriters or other similar body now or
hereafter constituted. Tenant shall not do or permit anything to be done in,
on, under or about the Project or bring or keep anything which will in any way
increase the rate of any insurance upon the Premises, Building or Project or
upon any contents therein or cause a cancellation of said insurance or
otherwise affect said insurance in any manner. Tenant shall indemnify, defend
(by counsel reasonably acceptable to Landlord), protect and hold Landlord
harmless from and against any loss, cost, expense, damage, attorneys' fees or
liability arising out of the failure of Tenant to comply with any Regulation.
Tenant's obligations pursuant to the foregoing indemnity shall survive the
expiration or earlier termination of this Lease with respect to matters first
arising or occurring prior to the expiration or termination of this Lease.

D.  Tenant shall have the sole responsibility for complying, at Tenant's cost,
with any ad all provisions of the Americans with Disabilities Act of 1990, as
it has been and may later be amended ("ADA"), (i) with respect to the Premises
and the common areas of the Project where such compliance has been brought
about by (A) any Tenant Improvements or Alterations to the Premises or to the
common areas made by or on behalf of Tenant, whether by Landlord or otherwise,
and whether performed before or after the Term Commencement Date; (B)
requirements of Tenant's employees, or any changes to Tenant's use of the
Premises; or (C) any architectural barriers caused by Tenant's installation of
any equipment, fixtures, furniture, or other personal property in or about the
Premises (collectively, "TENANT'S ADA RESPONSIBILITIES"). Tenant shall
indemnify, defend and hold Landlord, its agents and employees harmless from and
against any and all claims, damages, or liabilities (including, without
limitation, reasonable attorneys' fees and costs) arising directly or
indirectly from Tenant's failure to satisfy any of Tenant's ADA
Responsibilities. Landlord shall indemnify, defend and hold Tenant, its agents
and employees harmless from and against any and all claims, damages or
liabilities arising directly or indirectly from Landlord's failure to comply
with any obligations of a landlord under the ADA, other than such claims,
damages or liabilities arising from Tenant's failure to satisfy any of Tenant's
ADA Responsibilities; provided, however, that Landlord may treat costs of ADA
compliance with respect to the common areas of the Project to the extent
incurred after the Term Commencement Date as an Operating Expense provided
under Paragraph 7.A.

E.  Except for Tenant's obligations under Paragraph C and D above, Landlord
shall be responsible for complying with Regulations (including the ADA)
pertaining to the common areas of the Project prior to and except to the extent
arising out of Tenant's occupancy or use of the premises or common areas or
construction of any Tenant Improvements or Alterations made by or on behalf of
Tenant, whether by Landlord or otherwise and whether performed before or after
the Term Commencement Date, or installation of any equipment, fixtures,
furniture or other personal property in or about the Premises; provided,
however, that Landlord may treat costs of such compliance as an Operating
Expense as and to the extent provided under Paragraph 7.A.

F.  HAZARDOUS MATERIALS. As used in this Lease, "HAZARDOUS MATERIALS" shall
include, but not be limited to, hazardous, toxic and radioactive materials and
those substances defined as "hazardous substances," "hazardous materials,"
"hazardous wastes," "toxic substances," or other similar designations in any
Regulation. Tenant shall not cause, or allow any of Tenant's Parties to cause,
any Hazardous Materials to be handled, used generated, stored, released or
disposed of in, on under or about the Premises, the Building or the Project or
surrounding land or environment in violation of any Regulations. Tenant must
obtain Landlord's written consent prior to the introduction of any Hazardous
Materials onto the Project. Notwithstanding the foregoing, Tenant may handle,
store, use and dispose of product containing small quantities of Hazardous
Materials for "general office purposes" (such as toner for copiers) to the
extent customary and necessary for the Permitted Use of the Premises; provided
that Tenant shall always handle, store, use, and dispose of any such Hazardous
Materials in a safe and lawful manner and never allow such Hazardous Materials
to contaminate the Premises, Building, or Project or surrounding land or
environment.  Tenant shall use its best efforts to immediately notify Landlord
in writing of any Hazardous Materials' contamination of any portion of the
Project of which Tenant becomes aware, whether or not caused by Tenant.
Landlord shall have the right at all reasonable times to inspect the Premises
and to conduct tests and investigations to determine whether Tenant is in
compliance with the foregoing provisions. Tenant shall reimburse Landlord for
the costs of any such inspection, test and investigation that discloses
contamination for which Tenant is liable or if Landlord had reason to believe
contamination may have occurred. Tenant shall indemnify, defend (by counsel
reasonably acceptable to Landlord), protect and hold Landlord harmless from and
against any and all claims, liabilities, losses, costs, loss of rents, liens,
damages, injuries or expenses (including attorneys' and consultants' fees and
court costs), demands, causes of action, or judgments directly or indirectly
arising out of or related to the use, generation, storage, release, or disposal
of Hazardous Materials by Tenant or any of Tenant's Parties in, on, under or
about the Premises, the Building or the Project or surrounding land or
environment, which indemnity shall include without limitation, damages for
personal or bodily injury, property damage, damage to the environment or
natural resources occurring on or off the Premises, losses attributable to
diminution in value or adverse effects on marketability, the cost of any
investigation, monitoring, government oversight, repair, removal, remediation,
restoration, abatement, and disposal, and the preparation of any closure or
other required plans, whether such action is required or necessary prior to or
following the expiration or earlier termination of this Lease. Neither the
consent by Landlord to the use, generation, storage, release or disposal of
Hazardous Materials nor the strict compliance by Tenant with all laws
pertaining to Hazardous Materials shall excuse Tenant from Tenant's obligation
of indemnification pursuant to this Paragraph 4.D. Tenant's obligations
pursuant to the foregoing indemnity shall survive the expiration or earlier
termination if this Lease with respect to matters first arising or occurring
prior to the expiration or termination of this Lease.

day of each calendar month, in lawful money of the United States, without
deduction or offset whatsoever, at the Remittance Address specified in the Basic
Lease Information or to such other place as Landlord may from time to time
designate in writing. Base Rent for the first full month of the Term shall be
paid by Tenant upon Tenant's execution of this Lease. If the obligation for
payment of Base Rent commences on a day other than the first day of a month,
then Base Rent shall be prorated and the prorated installment shall be paid on

The Base Rent payable by Tenant hereunder is subject to adjustment as provided
elsewhere in this Lease, as applicable. As used herein, the term "Base Rent"

so adjusted from time to time.

B.  ADDITIONAL RENT. All monies other than Base Rent required to be paid by
Tenant hereunder, including, but not limited to Tenant's Proportionate Share of
Operating Expenses, as specified in Paragraph 7 of this Lease, charges to be

hereunder, Tenant shall pay as Additional Rent, Tenant's Proportionate share of
the Building and/or Project (as applicable), as defined in the Basic Lease
Information, of Operating Expenses (defined below) in the manner set forth

Operating Expenses. Landlord and Tenant acknowledge that if the number of
buildings which constitute the Project increases or decreases, or if physical
changes are made to the Premises, Building or Project or the configuration of
any thereof, Landlord may at its discretion reasonably adjust Tenant's
Proportionate Share of the Building or Project to reflect the change. Landlord's
determination of Tenant's Proportionate Share of the Building and of the Project
shall be conclusive so long as it is reasonably and consistently applied.
"OPERATING EXPENSES" shall mean all expenses and costs of every kind and nature
which Landlord shall pay or become obligated to pay, because of or in connection
with the ownership, management, maintenance, repair, preservation, replacement
and operation of the Building or project and its supporting facilities and such
additional facilities now and in subsequent years as may be determined by
Landlord to be necessary or desirable to the Building and/or Project (as
determined in a reasonable manner) other than those expenses and costs which are
specifically attributable to Tenant or which are expressly made the financial
responsibility of Landlord or specific tenants of the Building or Project
pursuant to this Lease. Operating Expenses shall include, but are not limited
to, the following:

      charged, confirmed, or imposed by any public authority upon the Building
      or Project, its operations or the Rent (or any portion or component
      thereof), or any tax, assessment or fee imposed in substitution, partially
      or totally, of any of the above. Operating Expenses shall also include any
      taxes, assessments, reassessments, or other fees or impositions with
      respect to the development, leasing, management, maintenance, alteration,
      repair, use or occupancy of the Premises, Building, or Project or any
      portion thereof, including, without limitation, by or for Tenant, and all
      increases therein or reassessments thereof whether the increases or
      reassessments result from increased rate and/or valuation (whether upon a
      transfer of the Building or Project or any portion thereof or any interest
      therein or for any other reason). Operating Expenses shall not include
      inheritance or estate taxes imposed upon or assessed against the interest
      of any person in the Project, or taxes computed upon the basis of the net
      income of any owners of any interest in the Project. If it shall not be
      lawful for Tenant to reimburse Landlord for all or any part of such taxes.

            the financial responsibility of Landlord pursuant to Paragraph 10
            hereof; those items to the extent paid for by the proceeds of
            insurance; and those items attributable solely or jointly to
            specific tenants of the Building or Project.

            (b)  Repairs, replacements, and general maintenance shall include
            the cost of any capital improvements made to or capital assets
            acquired for the Project or Building that in Landlord's discretion
            may reduce any other Operating Expenses, including present or future
            repair work, are reasonably necessary for the health and safety of
            the occupants of the Building or Project, or are required to comply
            with any Regulation, such costs or allocable portions thereof to be
            amortized over such reasonable period as Landlord shall determine,
            which is in accordance with generally accepted accounting
            principles, together with interest on the unamortized balance at the
            publicly announced "prime rate" charged by Wells Fargo Bank, N.A.

            capital assets

            are constructed or acquired, plus two (2) percentage points, or in
            the absence of such prime rate, then at the U.S. Treasury six-month
            market note (or bond, if so designated) rate as published by any
            national financial publication selected by Landlord, plus four (4)
            percentage points, but in no event more than the maximum rate
            permitted by law, plus reasonable financing charges.

            (c)  Payment under or for any easement, license, permit, operating
            agreement, declaration, restrictive covenant or instrument relating
            to the Building or Project.

            (d)  All expenses and rental related to services and costs of
            supplies, materials and equipment used in operating, managing and
            maintaining the Premises, Building and Project, the equipment
            therein and the adjacent sidewalks, driveways, parking and service
            areas, including, without limitation, expenses related to service
            agreements regarding security, fire and other alarm systems,
            janitorial services, window cleaning, elevator maintenance, Building
            exterior maintenance, landscaping and expenses related to the

            (e) The cost of supplying any services and utilities which benefit
            all or a portion of the Premises, Building or Project, including

            Paragraph 15 hereof.

            (f) Legal expenses and the cost of audits by certified public
            accountants; provided, however, that legal expenses chargeable as

            incurred in legal proceedings with or against any tenant or to
            enforce the provisions of any lease.

            percent (5%) of the sum of the Project's base rents and Operating
            Expenses (other than such management and accounting fee).

If the rentable area of the Building and/or Project is not fully occupied during
any fiscal year of the Term as determined by Landlord, an adjustment may be made
in Landlord's discretion in computing the Operating Expenses for such year so
that Tenant pays an equitable portion of all variable items (e.g., utilities,
janitorial services and other component expenses that are affected by variations
in occupancy levels) of Operating Expenses, as reasonably determined by
Landlord; provided, however, that in no event shall Landlord be entitled to
collect in excess of one hundred percent (100%) of the total Operating Expenses
from all of the tenants in the Building or Project, as the case may be.

Operating Expenses shall not include the cost of providing tenant improvements
or other specific costs incurred for the account of, separately billed to and
paid by specific tenants of the Building or Project, the initial construction
cost of the Building, or debt service on any mortgage or deed of trust recorded
with respect to the Project other than pursuant to Paragraph 7.A.(3)(b) above.
Notwithstanding anything herein to the contrary, in any instance wherein
Landlord, in Landlord's reasonable discretion, deems Tenant to be responsible
for any amounts greater than Tenant's Proportionate Share, Landlord shall have
the right to allocate costs in any manner Landlord deems appropriate.

this Lease to the contrary, Operating Expenses shall not include the following,
except to the extent specifically provided:

(i)    Any ground lease rental;

       to the Building or Project which is used in providing janitorial or
       similar services);

(iv)   Costs incurred by Landlord for the repair of damage to the Building or
       Project excluding a reasonable deductible not to exceed one Dollar

       consummation of any financing or refinancing of the Project;

(ix)   Except for making repairs or keeping permanent systems in operation while
       repairs are being made, rentals and other related expenses incurred in
       leasing air conditioning systems, elevators or other equipment ordinarily

       Building or Project which is used in providing janitorial or similar
       services;

        those other than Tenant and Tenant's Parties.

The above enumeration of services and facilities shall not be deemed to impose
an obligation on Landlord to make available or provide such services or
facilities except to the extent if any that Landlord has specifically agreed
elsewhere in this Lease to make the same available or provide the same. Without
limiting the generality of the foregoing, Tenant acknowledges and agrees that it
shall be responsible for providing adequate security for its use of the
Premises, the Building and the Project and that Landlord shall have no
obligation or liability with respect thereto, except to the extent if any that
Landlord has specifically agreed elsewhere in this Lease to provide the same.

B.      PAYMENT OF ESTIMATED OPERATING EXPENSES. "ESTIMATED OPERATING EXPENSES"
for any particular year shall mean Landlord's estimate of the Operating Expenses
for such fiscal year made with respect to such fiscal year as hereinafter
provided. Landlord shall have the right from time to time to revise its fiscal
year and interim accounting periods so long as the periods as so revised are
reconciled with prior periods in a reasonable manner. During the last month of
each fiscal year during the Term, or as soon thereafter as practicable, Landlord
shall give Tenant written notice of the Estimated Operating Expenses for the
ensuing fiscal year. Tenant shall pay Tenant's Proportionate Share of the
Estimated Operating Expenses with installments of Base Rent for the fiscal year
to which the Estimated Operating Expenses applies in monthly installments on the
first day of each calendar month during such year, in advance. Such payment
shall be construed to be Additional Rent for all purposes hereunder. If at any
time during the course of the fiscal year, Landlord determines that Operating
Expenses are projected to vary from the then Estimated Operating Expenses by
more than five percent (5%), Landlord may, by written notice to Tenant, revise
the Estimated Operating Expenses for the balance of such fiscal year, and
Tenant's monthly installments for the remainder of such year shall be adjusted
so that by the end of such fiscal year Tenant has paid to Landlord Tenant's
Proportionate Share of the revised Estimate Operating Expenses for such year,
such revised installment amounts to be Additional Rent for all purposes
hereunder.

C.      COMPUTATION OF OPERATING EXPENSE ADJUSTMENT. "OPERATING EXPENSE
ADJUSTMENT" shall mean the difference between Estimated Operating Expenses and
actual Operating Expenses for any fiscal year determined as hereinafter
provided. Within one hundred twenty (120) days after the end of each fiscal
year, or as soon thereafter as practicable, Landlord shall deliver to Tenant a
statement of actual Operating Expenses for the fiscal year just ended,
accompanied by a computation of Operating Expense Adjustment. If such statement
shows that Tenant's payment based upon Estimated Operating Expenses is less that
Tenant's Proportionate Share of Operating Expenses, then Tenant shall pay to
Landlord the difference within twenty (20) days after receipt of such statement,
such payment to constitute Additional Rent for all purposes hereunder. If such
statement shows that Tenant's payments of Estimated Operating Expenses exceed
Tenant's Proportionate Share of Operating Expenses, then (provided that Tenant
is not in default under this Lease) Landlord shall pay to Tenant the difference
within twenty (20) days after delivery of such statement to Tenant. If this
Lease has been terminated or the Term hereof has expired prior to the date of
such statement, then the Operating Expense Adjustment shall be paid by the
appropriate party within twenty (20) days after the date of delivery of the
statement. Should this Lease commence or terminate at any time other than the
first day of the fiscal year, Tenant's Proportionate Share of the Operating
Adjustment shall be prorated based on a month of 30 days and the number of
calendar months during such fiscal year that this Lease is in effect.
Notwithstanding anything to the contrary contained in Paragraph 7.A or 7.B,
Landlord's failure to provide any notices or statements within the time periods
specified in those paragraphs shall in no way excuse Tenant from its obligation
to pay Tenant's Proportionate Share of Operating Expenses.

D.      NET LEASE. This shall be a triple net Lease and Base Rent shall be paid
to Landlord absolutely net of all costs and expenses, except as specifically
provided to the contrary in this Lease. The provisions for payment of Operating
Expenses and the Operating Expense Adjustment are intended to pass on to Tenant
and reimburse Landlord for all costs and expenses of the nature described in
Paragraph 7.A. incurred in connection with the ownership, management,
maintenance, repair, preservation, replacement and operation of the Building
and/or Project and its supporting facilities and such additional facilities now
and in subsequent years as may be determined by Landlord to be necessary or
desirable to the Building and/or Project.

E.      TENANT AUDIT. If Tenant shall dispute the amount set forth in any
statement provided by Landlord under Paragraph 7.B. or 7.C. above, Tenant shall
have the right, not later than forty-five (45) days following receipt of such
statement and upon the condition that Tenant shall first deposit with Landlord
the full amount in dispute, to cause Landlord's books and records with respect
to Operating Expenses for such fiscal year to be audited by certified public
accountants selected by Tenant and subject to Landlord's reasonable right of
approval. The Operating Expense Adjustment shall be appropriately adjusted on
the basis of such audit. If such audit discloses a liability for a refund in
excess of ten percent (10%) of Tenant's Proportionate Share of the Operating
Expenses previously reported, the cost of such audit shall be borne by Landlord;
otherwise the cost of such audit shall be paid by Tenant. If Tenant shall not
request an audit in accordance with the provisions of this Paragraph 7.E. within
forty-five (45) days after receipt of Landlord's statement provided pursuant to
Paragraph 7.B. or 7.C., such statement shall be final and binding for all
purposes hereof.

                       8.  INSURANCE AND INDEMNIFICATION

A.      LANDLORD'S INSURANCE. All insurance maintained by Landlord shall be for
the sole benefit of Landlord and under Landlord's sole control.

        (1)   PROPERTY INSURANCE. Landlord agrees to maintain property insurance
        insuring the Building against damage or destruction due to risk
        including fire, vandalism, and malicious mischief in an amount not less
        than the replacement cost thereof, in the form and with deductibles and
        endorsements as selected by Landlord. At its election, Landlord may
        instead (but shall have no obligation to) obtain "All Risk" coverage,
        and may also obtain earthquake, pollution, and/or flood insurance in
        amounts selected by Landlord.
<PAGE>
      (2)    OPTIONAL INSURANCE. Landlord, at Landlord's option, may also (but
      shall have not obligation to) carry insurance against loss of rent, in an
      amount equal to the amount of Base Rent and Additional Rent that Landlord
      could be required to abate to all Building tenants in the event of
      condemnation or casualty damage for a period of twelve (12) months.
      Landlord may also (but shall have no obligation to) carry such other
      insurance as Landlord may deem prudent or advisable, including, without
      limitation, liability insurance in such amounts and on such terms as
      Landlord shall determine. Landlord shall not be obligated to insure, and
      shall have no responsibility whatsoever for any damage to, any furniture,
      machinery, goods, inventory or supplies, or other personal property or
      fixtures which Tenant may keep or maintain in the Premises, or any
      leasehold improvements, additions or alterations within the Premises.

B.    TENANT'S INSURANCE.

      (1)    PROPERTY INSURANCE. Tenant shall procure at Tenant's sole cost and
      expense and keep in effect from the date of this Lease and at all times
      until the end of the Term, insurance on all personal property and fixtures
      of Tenant and all improvements, additions or alterations made by or for
      Tenant to the Premises on an "All Risk" basis, insuring such property for
      the full replacement value of such property.

      (2)   LIABILITY INSURANCE. Tenant shall procure at Tenant's sole cost and
      expense and keep in effect from the date of this Lease and at all times
      until the end of the Term Commercial General Liability insurance covering
      bodily injury and property damage liability occurring in or about the
      Premises or arising out of the use and occupancy of the Premises and the
      Project, and any part of either, and any areas adjacent thereto, and the
      business operated by Tenant or by any other occupant of the Premises. Such
      insurance shall include contractual liability insurance coverage insuring
      all of Tenants's indemnity obligations under this Lease. Such coverage
      shall have a minimum combined single limit of liability of at least Two
      Million Dollars ($2,000,000.00), and a minimum general aggregate limit of
      Three Million Dollars ($3,000,000.00), with an "Additional Insured ??
      Managers or Lessors of Premises Endorsement." All such policies shall be
      written to apply to all bodily injury (including death), property damage
      or loss, personal and advertising injury and other covered loss, however
      occasioned, occurring during the policy term, shall be endorsed to add
      Landlord and any party holding an interest to which this Lease may be
      subordinated as an additional insured, and shall provide that such
      coverage shall be "PRIMARY" and non-contributing with any insurance
      maintained by Landlord, which shall be excess insurance only. Such
      coverage shall also contain endorsements including employees as additional
      insureds if not covered by Tenant's Commercial General Liability
      Insurance. All such insurance shall provide for the severability of
      interests of insureds: and shall be written on an "OCCURRENCE" basis,
      which shall afford coverage for all claims based on acts, omissions,
      injury and damage, which occurred or arose (or the onset of which occurred
      or arose) in whole or in part during the policy period.

      (3)   WORKERS' COMPENSATION AND EMPLOYERS' LIABILITY INSURANCE. Tenant
      shall carry Workers' Compensation Insurance as required by any Regulation,
      throughout the Term at Tenant's sole cost and expense. Tenant shall also
      carry Employers' Liability Insurance in amounts not less than One Million
      Dollars ($1,000,000) each accident for bodily injury by accident; One
      Million Dollars ($1,000,000) policy limit for bodily injury by disease;
      and One Million Dollars ($1,000,000) each employee for bodily injury by
      disease, throughout the Term at Tenant's sole cost and expense.

      (4)   GENERAL INSURANCE REQUIREMENTS. All coverages described in this
      Paragraph 8.B. shall be endorsed to (i) provide Landlord with thirty (30)
      days' notice of cancellation or change in terms; and (ii) waive all rights
      of subrogation by the insurance carrier against Landlord. If at any time
      during the Term the amount or coverage of insurance which Tenant is
      required to carry under this Paragraph 8.B. is, in Landlord's reasonable
      judgment, materially less than the amount or type of insurance coverage
      typically carried by owners or tenants of properties located in the
      general area in which the Premises are located which are similar to and
      operated for similar purposes as the Premises or if Tenant's use of the
      Premises should change with or without Landlord's consent, Landlord shall
      have the right to require Tenant to increase the amount or change the
      types of insurance coverage required under this Paragraph 8.B. All
      insurance policies required to be carried by Tenant under this Lease shall
      be written by companies rated A X or better in "Best's Insurance Guide"
      and authorized to do business in the State of California. In any event
      deductible amounts under all insurance policies required to be carried by
      Tenant under this Lease shall not exceed Ten Thousand Dollars ($10,000.00)
      per occurrence. Tenant shall deliver to Landlord on or before the Term
      Commencement Date, and thereafter at least thirty (30) days before the
      expiration dates of the expired policies, copies of Tenant's insurance
      certificate evidencing the same issued by the insurer thereunder; and, if
      Tenant shall fail to procure such insurance, or to deliver such
      certificates, Landlord may, at Landlord's option and in addition to
      Landlord's other remedies in the event of a default by Tenant hereunder,
      procure the same for the account of Tenant, and the cost thereof shall be
      paid to Landlord as Additional Rent.

C.    INDEMNIFICATION. Tenant shall indemnify, defend by counsel reasonably
acceptable to Landlord, protect and hold Landlord harmless from and against any
and all claims, liabilities, losses, costs, loss of rents, liens, damages,
injuries or expenses, including reasonable attorneys' and consultants' fees and
court costs, demands, causes of action, or judgments, directly or indirectly
arising out of or related to: (1) claims of injury to or death of persons or
damage to property occurring or resulting directly or indirectly from the use or
occupancy of the Premises, Building or Project by Tenant or Tenant's Parties, or
from activities or failures to act of Tenant or Tenant's Parties; (2) claims
arising from work or labor performed, or for materials or supplies furnished to
or at the request or for the account of Tenant in connection with performance of
any work done for the account of Tenant within the Premises or Project; (3)
claims arising from any breach or default on the part of Tenant in the
performance of any covenant contained in this Lease; and (4) claims arising from
the negligence or intentional acts or omissions of Tenant or Tenant's Parties.
The foregoing indemnity by Tenant shall not be applicable to claims to the
extent arising from the gross negligence or willful misconduct of Landlord,
Landlord's agents, employees and representatives. Landlord shall not be liable
to Tenant and Tenant hereby waives all claims against Landlord for any injury or
damage to any person or property in or about the Premises, Building or Project
by or from any cause whatsoever (other than Landlord's, Landlord's agent's,
employee's and representative's gross negligence or willful misconduct) and,
without limiting the generality of the foregoing, whether caused by water
leakage of any character from the roof, walls, basement or other portion of the
Premises, building or Project, or caused by gas, fire, oil or electricity in, on
or about the Premises, Building or Project. The provisions of this Paragraph
shall survive the expiration or earlier termination of this Lease.

                           9.  WAIVER OF SUBROGATION

     To the extent permitted by law and without affecting the coverage provided
by insurance to be maintained hereunder or any other rights or remedies,
Landlord and Tenant each waive any right to recover against the other for: (a)
damages for injury to or death of persons; (b) damages to property, including
personal property; (c) damages to the Premises or any part thereof; and (d)
claims arising by reason of the foregoing due to hazards covered by insurance
maintained or required to be maintained pursuant to this Lease to the extent of
proceeds recovered therefrom, or proceeds which would have been recoverable
therefrom in the case of the failure of any party to maintain any insurance
coverage required to be maintained by such party pursuant to this Lease. This
provision is intended to waive fully, any rights and/or claims arising by reason
of the foregoing, but only to the extent that any of the foregoing damages
and/or claims referred to above are covered or would be covered, and only to the
extent of such coverage, by insurance actually carried or required to be
maintained
<PAGE>
pursuant to this Lease by either Landlord or Tenant. This provision is also
intended to waive fully, and for the benefit of each party, any rights and/or
claims which might give rise to a right of subrogation on any insurance
carrier. Subject to all qualifications of this Paragraph 9, Landlord waives its
rights as specified in this Paragraph 9 with respect to any subtenant that it
has approved pursuant to Paragraph 21 but only in exchange for the written
waiver of such rights to be given by such subtenant to Landlord upon such
subtenant taking possession of the Premises or a portion thereof. Each party
shall cause each insurance policy obtained by it to provide that the insurance
company waives all right of recovery by way of subrogation against either
party in connection with any damage covered by any policy.

                    10.  LANDLORD'S REPAIRS AND MAINTENANCE

     Landlord shall at Landlord's expense maintain in good repair, reasonable
wear and tear excepted, the structural soundness of the roof, foundations, and
exterior walls of the Building. The term "exterior walls" as used herein shall
not include windows, glass or plate glass, doors, special store fronts or
office entries. Landlord shall also maintain and repair the Building Systems,
Common Areas and Parking Areas, the cost of which shall be included in
Operating Expenses to the extent permitted under Paragraph 7. Any damage cause
by or repairs necessitated by any negligence or act of Tenant or Tenant's
parties may be repaired by Landlord at Landlord's option and Tenant's expense.
Tenant shall immediately give Landlord written notice of any defect or need of
repairs in such components of the Building for which Landlord is responsible,
after which Landlord shall have a reasonable opportunity and the right to enter
the Premises at all reasonable times to repair same. Landlord's liability with
respect to any defects, repairs, or maintenance for which Landlord is
responsible under any of the provisions of this Lease shall be limited to the
cost of such repairs or maintenance, and there shall be no abatement of rent
and no liability of Landlord by reason of any injury to or interference with
Tenant's business arising from the making of repairs, alterations or
improvements in or to any portion of the Premises, the Building or the Project
or to fixtures, appurtenances or equipment in the Building, except as provided
in Paragraph 24. By taking possession of the Premises, Tenant accepts them "as
is" as being in good order, condition and repair and the condition in which
Landlord is obligated to deliver them and suitable for the Permitted Use and
Tenant's intended operations in the Premises, whether or not any notice of
acceptance is given.

                     11.  TENANT'S REPAIRS AND MAINTENANCE

     Tenant shall at all times during the Term at Tenant's expense maintain all
parts of the Premises and such portions of the Building as are within the
exclusive control of Tenant in a first-class, good, clean and secure condition
and promptly make all necessary repairs and replacements, as reasonably
determined by Landlord, with materials and workmanship of the same character,
kind and quality as the original. Notwithstanding anything to the contrary
contained herein, Tenant shall, at its expense, promptly repair any damage to
the Premises caused by any negligence or act of Tenant or Tenant's Parties and
Tenant shall, at its expense, promptly repair any damage to the Building or
Project resulting from or caused by any active negligence or intentional act of
Tenant or Tenant's Parties to the extent Tenant shall only be liable for such
costs that Landlord's insurance award proceeds do not provide.

                                12.  ALTERATIONS

A.        Tenant shall not make, or allow to be made, any alterations, physical
additions, improvements or partitions, including without limitation the
attachment of any fixtures or equipment, in, about or to the Premises
("ALTERATIONS") without obtaining the prior written consent of Landlord, which
consent shall not be unreasonably withheld with respect to proposed Alterations
which: (a) comply with all applicable Regulations; (b) are, in Landlord's
opinion, compatible with the Building or the Project and its mechanical,
plumbing, electrical, heating/ventilation/air conditioning systems, and will not
cause the Building or Project or such systems to be required to be modified to
comply with any Regulations (including, without limitation, the Americans With
Disabilities Act); and (c) will not interfere with the use and occupancy of any
other portion of the Building or Project by any other tenant or its invitees.
Specifically, but without limiting the generality of the foregoing, Landlord
shall have the right of written consent for all plans and specifications for the
proposed Alterations, construction means and methods, all appropriate permits
and licenses, any contractor or subcontractor to be employed on the work of
Alterations, and the time for performance of such work, and may impose rules and
regulations for contractors and subcontractors performing such work. Tenant
shall also supply to Landlord any documents and information reasonably requested
by Landlord in connection with Landlord's consideration of a request for
approval hereunder. Tenant shall cause all Alterations to be accomplished in a
first-class, good and workmanlike manner, and to comply with all applicable
Regulations and Paragraph 27 hereof. Tenant shall at Tenant's sole expense,
perform any additional work required under applicable Regulations due to the
Alterations hereunder. No review or consent by Landlord of or to any proposed
Alteration or additional work shall constitute a waiver of Tenant's obligations
under this Paragraph 12, nor constitute any warranty or representation that the
same complies with all applicable Regulations, for which Tenant shall at all
times be solely responsible. Tenant shall reimburse Landlord for all reasonable
costs which Landlord may incur in connection with granting approval to Tenant
for any such Alterations, including any costs or expenses which Landlord may
incur in electing to have outside architects and engineers review said plans and
specifications and Tenant shall pay Landlord an administration fee of fifteen
percent (15%) of the cost of the Alterations for those Alterations performed by
Landlord on Tenant's account up to Twenty-five Thousand Dollars ($25,000.00) as
Additional Rent hereunder. Landlord's administrative fee for Alterations
performed by Landlord on Tenant's account above Twenty-five Thousand Dollars
($25,000.00) shall be determined at the time of such Alterations. All such
Alterations shall remain the property of Tenant until the expiration or earlier
termination of this Lease, at which time they shall be and become the property
of Landlord; provided, however, that Landlord may, at Landlord's option, require
that Tenant, at Tenant's expense, remove any or all Alterations made by Tenant
and restore the Premises by the expiration or earlier termination of this Lease,
to their condition existing prior to the construction of any such Alterations.
All such removals and restoration shall be accomplished in a first-class and
good and workmanlike manner so as not to cause any damage to the Premises or
Project whatsoever. If Tenant fails to remove such Alterations or Tenant's trade
fixtures or furniture or other personal property, Landlord may keep and use them
or remove any of them and cause them to be stored or sold in accordance with
applicable law, at Tenant's sole expense. In addition to and wholly apart from
Tenant's obligation to pay Tenant's Proportionate Share of Operating Expenses,
Tenant shall be responsible for and shall pay prior to delinquency any taxes or
governmental service fees, possessory interest taxes, fees or charges in lieu of
any such taxes, capital levies, or other charges imposed upon, levied with
respect to or assessed against its fixtures or personal property, on the value
of Alterations within the Premises, and on Tenant's interest pursuant to this
Lease, or any increase in any of the foregoing based on such Alterations. To the
extent that any such taxes are not separately assessed or billed to Tenant,
Tenant shall pay the amount thereof as invoiced to Tenant by Landlord.

Notwithstanding the foregoing, at Landlord's and Tenant's option (but without
obligation), all or any portion of the Alterations shall be performed by
Landlord for Tenant's account and upon mutual agreement between Landlord and
Tenant, Tenant shall pay Landlord's estimate of the cost thereof (including a
reasonable charge for Landlord's overhead and profit) prior to commencement of
the work. In addition, at Landlord's election and notwithstanding the
foregoing, however, Tenant shall pay to Landlord the cost of removing any such
Alterations and restoring the Premises to their original condition such cost to
include a reasonable charge for Landlord's overhead and profit as provided
above, and such amount may be deducted from the Security Deposit or any other
sums or amounts held by Landlord under this Lease.

Notwithstanding anything to the contrary contained in Paragraph 12.A, at the
time Landlord gives its consent for any Alterations, Tenant shall also be
notified whether or not Landlord will require that such Alterations be removed
upon the expiration or earlier termination of this Lease. Landlord shall provide
<PAGE>
consent or rejection of the proposed Alterations within ten (10) business days
of receipt of Tenant's request. If Landlord's consent is withheld, Landlord
shall provide Tenant with written notice of the reason its consent to the
Alterations was withheld.

B.        In compliance with Paragraph 27 hereof, at least ten (10) business
days before beginning construction of any Alteration, Tenant shall give
Landlord written notice of the expected commencement date of that construction
to permit Landlord to post and record a notice of non-responsibility. Upon
substantial completion of construction, if the law so provides, Tenant shall
cause a timely notice of completion to be recorded in the office of the
recorder of the county in which the Building is located.

                                   13.  SIGNS

Tenant shall not place, install, affix, paint or maintain any signs, notices,
graphics or banners whatsoever or any window decor which is visible in or from
public view or corridors, the common areas or the exterior of the Premises or
the Building, in or on any exterior window or window fronting upon any common
areas or service area without Landlord's prior written approval which Landlord
shall have the right to withhold in its reasonable discretion; provided that
Tenant's name shall be included in any Building-standard door and directory
signage, if any, in accordance with Landlord's Building signage program,
including without limitation, payment by Tenant of any fee charged by Landlord
for maintaining such signage, which fee shall constitute Additional Rent
hereunder. Any installation of signs, notices, graphics or banners on or about
the Premises or Project approved by Landlord shall be subject to any
Regulations and to any other requirements imposed by Landlord. Tenant shall
remove all such signs or graphics by the expiration or any earlier termination
of this Lease. Such Installations and removals shall be made in such manner as
to avoid injury to or defacement of the Premises, Building or Project and any
other improvements contained therein, and Tenant shall repair any injury or
defacement including without limitation discoloration caused by such
installation or removal.

                        14.  INSPECTION/POSTING NOTICES

After reasonable notice, except in emergencies where no such notice shall be
required, Landlord, and Landlord's agent, employees and representative, shall
have the right to enter the Premises to inspect the same, to clean, to perform
such work as may be permitted or required hereunder, to make repairs,
improvements or alterations to the Premises, Building or Project or to other
tenant spaces therein, to deal with emergencies, to post such notices as may be
permitted or required by law to prevent the perfection of lens against
Landlord's interest in the Project or to exhibit the Premises to prospective
tenants, purchasers, encumbrancers or to others, or for any other purpose as
Landlord may deem necessary or desirable; provided, however, that Landlord
shall use reasonable efforts not to unreasonably interfere with Tenant's
business operations. Tenant shall not be entitled to any abatement of Rent by
reason of the exercise of any such right of entry. Tenant waives any claim for
damages for any injury or inconvenience to or interference with Tenant's
business, any loss of occupancy or quit enjoyment of the Premises, and any
other loss occasioned thereby. 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 or special security areas (designated in
advance), and Landlord shall have the right to use any and all means which
Landlord may deem necessary or proper to open said doors in an emergency, in
order to obtain entry to any portion of the Premises, and any entry to the
Premises or portions thereof obtained by Landlord by any of said means, or
otherwise, shall not be construed 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 portions thereof. At any time within six (6) months
prior to the expiration of the Term or following any earlier termination of
this Lease or agreement to terminate this Lease, Landlord shall have the right
to erect on the Premises, Building and/or Project a suitable sign indicating
that the Premises are available for lease.

                          15.  SERVICES AND UTILITIES

A.        Subject to the provisions elsewhere herein contained and to the rules
and regulations of the Building, Landlord shall furnish to the Premises during
ordinary business hours of generally recognized business days, to be determined
by Landlord (but exclusive, in any event, of Saturdays, Sundays and legal
holidays), water for lavatory and drinking purposes and electricity, heat and
air conditions as usually furnished or supplied for use of the Premises for
reasonable and normal office use as of the date Tenant takes possession of the
Premises as determined by Landlord (but not including above-standard or
continuous cooling for excessive heat-generating machines, excess lighting or
equipment), janitorial services during the times and in the manner that such
services are, in Landlord's judgment, customarily furnished in comparable first
class office buildings in the immediate Foster City market area, and elevator
service, which shall mean service either by nonattended automatic elevators or
elevators with attendants, or both, at the option of Landlord. Tenant
acknowledges and agrees that Tenant's use of the Premises after ordinary
business hours (defined as 7:00 a.m. to 6:00 p.m.) and outside of generally
recognized business days (generally recognized business days shall not include
Saturdays, Sundays, and legal holidays) imposes additional burden on the
Project's janitorial services, fluorescent light tubes, HVAC and electrical
service, and other common area utilities and services. Accordingly, any such
after hours use of such utilities or other services will be made available and
will be billed as an after-hour Rent assessment. After-hours use may be metered
by Landlord with a bypass timer located on the applicable floors of the
Building or through establishment of a monthly after hours assessment based
upon Landlord's reasonable estimate of Tenant's usage. Such costs will be
payable by Tenant to Landlord within thirty (30) days after demand as
Additional Rent. Tenant agrees to keep and cause to be kept closed all window
covering when necessary because of the sun's position, and Tenant also agrees
at all times to cooperate fully with Landlord and to abide by all of the
regulations and requirements which Landlord may prescribe for the proper
functioning and protection of electrical, heating, ventilating and air
conditioning systems. Wherever heat-generating machines, excess lighting or
equipment are used in the Premises which affect the temperature otherwise
maintained by the air conditioning system, Landlord reserves the right to
install supplementary air conditioning units in the Premises and the cost
thereof, including the cost of installation and the cost of operation and
maintenance thereof, shall be paid by Tenant to Landlord upon demand by
Landlord.

B.        Tenant shall not without written consent of Landlord, which consent
shall not be unreasonably withheld, conditioned or delayed, use any apparatus,
equipment or device in the Premises, including without limitation, computers,
electronic data processing machines, copying machines, and other machines, using
excess lighting or using electric current, water, or any other resource in
excess of or which will in any way increase the amount of electricity, water, or
any other resource being furnished or supplied for the use of the Premises for
reasonable and normal office use, in each case as of the date Tenant takes
possession of the Premises as reasonably determined by Landlord, or which will
require additions or alterations to or interfere with the Building power
distribution systems; nor connect with electric current, except through existing
electrical outlets in the Premises or water pipes, any apparatus, equipment or
device for the purpose of using electrical current, water, or any other
resource. If Tenant shall require water or electric current or any other
resource in excess of that being furnished or supplied for the use of the
Premises as of the date Tenant takes possession of the Premises as determined by
Landlord, Tenant shall first procure the written consent of Landlord which
Landlord may refuse, to the use thereof, and Landlord may cause a special meter
to be installed in the Premises so as to measure the amount of water, electric
current or other resource consumed for
<PAGE>

any such other use. Tenant shall pay directly to Landlord as an addition to and
separate from payment of Operating Expenses the cost of all such additional
resources, energy, utility service and meters (and of installation, maintenance
and repair thereof and of any additional circuits or other equipment necessary
to furnish such additional resources, energy, utility or service). Landlord may
add to the separate or metered charge a recovery of additional expense incurred
in keeping account of the excess water, electric current or other resource so
consumed. Landlord shall not be liable for any damages directly or indirectly
resulting from nor shall the Rent or any monies owed Landlord under this Lease
herein reserved be abated by reason of: (a) the installation, use or
interruption of use of any equipment used in connection with the furnishing of
any such utilities or services, or any change in the character or means of
supplying or providing any such utilities or services or any supplier thereof;
(b) the failure to furnish or delay in furnishing any such utilities or services
when such failure or delay is caused by acts of God or the elements, labor
disturbances of any character, or any other accidents or other conditions beyond
the reasonable control of Landlord or because of any interruption of service due
to Tenant's use of water, electric current or other resource in excess of that
being supplied or furnished for the use of the Premises as of the date Tenant
takes possession of the Premises; (c) the inadequacy, limitation, curtailment,
rationing or restriction on use of water, electricity, gas or any other form of
energy or any other service or utility whatsoever serving the Premises or
Project, whether by Regulation or otherwise; or (d) the partial or total
unavailability of any such utilities or services to the Premises or the
Building, whether by Regulation or otherwise, nor shall any such occurrence
constitute an actual or constructive eviction of Tenant. Notwithstanding the
foregoing, if such condition is caused solely by Landlord's active negligence
and not by Tenant or matters which are within Tenant's control, and if such
condition exists for more than fifteen (15) consecutive business days after
notice to Landlord and materially interferes with Tenant's use of a material
portion of the Premises, rental payments with respect to that portion of the
Premises so affected, shall abate after such fifteen (15) day period, in the
proportion that the rentable area of the affected area bears to the total
rentable area of the Premises, until such interference no longer exists or
Tenant reoccupies such portion of the Premises. Landlord shall further have no
obligation to protect or preserve any apparatus, equipment or device installed
by Tenant in the Premises, including without limitation by providing additional
or after-hours heating or air conditioning. Landlord shall be entitled to
cooperate voluntarily and in a reasonable manner with the efforts of national,
state or local governmental agencies or utility suppliers in reducing energy or
other resource consumption. The obligation to make services available hereunder
shall be subject to the limitations of any such voluntary, reasonable program.
In addition, Landlord reserves the right to change the supplier or provider of
any such utility or service from time to time. Tenant shall have no right to
contract with or otherwise obtain any electrical or other such service for or
with respect to the Premises or Tenant's operations therein from any supplier or
provider of any such service. Tenant shall cooperate with Landlord and any
supplier or provider of such services designated by Landlord from time to time
to facilitate the delivery of such services to Tenant at the Premises and to the
Building and Project, including without limitation allowing Landlord and
Landlord's suppliers or providers, and their respective agents and contractors,
reasonable access to the Premises for the purpose of installing, maintaining,
repairing, replacing or upgrading such service or any equipment or machinery
associated therewith.

C.        Tenant shall pay, upon demand, for all utilities furnished to the
Premises, or if not separately billed to or metered to Tenant, Tenant's
Proportionate share of all charges jointly serving the Project in accordance
with Paragraph 7. All sums payable under this Paragraph 15 shall constitute
Additional Rent hereunder.

                               16.  SUBORDINATION

Landlord represents and warrants to Tenant that, as of the date of this Lease,
no mortgages encumber the Project or the Building and that the Ground Lease (as
defined in Paragraph 39 below) is the only ground lease with respect to the
Project. Without the necessity of any additional document being executed by
Tenant for the purpose of effecting a subordination, this Lease shall be and is
hereby declared to be subject and subordinate at all times to: (a) all ground
leases or underlying leases which may now exist or hereafter be executed
affecting the Premises and/or the land upon which the Premises and Project are
situated, or both; and (b) any mortgage or deed of trust which may now exist or
be placed upon the Building, the Project and/or the land upon which the Premises
or the Project are situated, or said ground leases or underlying leases, or
Landlord's interest or estate in any of said items which is specified as
security, provided, however, that if no uncured Event of Default exists under
this Lease, such subordination shall be conditioned upon Tenant not being
disturbed in its possession and use of the Premises. Notwithstanding the
foregoing, Landlord shall have the right to subordinate or cause to be
subordinated any such ground leases or underlying leases or any such liens to
this Lease. If any ground lease or underlying lease terminates for any reason or
any mortgage or deed of trust is foreclosed or a conveyance in lieu of
foreclosure is made for any reason, Tenant shall, notwithstanding any
subordination, attorn to and become the Tenant of the successor in interest to
Landlord provided that Tenant shall not be disturbed in its possession under
this Lease by such successor in interest so long as Tenant is not in default
under this Lease. Within ten (10) days after request by Landlord, Tenant shall
execute and deliver any additional documents evidencing Tenant's attornment or
the subordination of this Lease with respect to any such ground leases or
underlying leases or any such mortgage or deed of trust, in the form requested
by Landlord or by any ground landlord, mortgagee, or beneficiary under a deed of
trust, subject to such nondisturbance requirement. If requested in writing by
Tenant, Landlord shall use commercially reasonable efforts to obtain a
subordination, nondisturbance and attornment agreement for the benefit of Tenant
reflecting the foregoing from any ground landlord, mortgagee or beneficiary, at
Tenant's expense, subject to such other terms and conditions as the ground
landlord, mortgagee or beneficiary may require.

                           17.  FINANCIAL STATEMENTS

At the request of Landlord from time to time, Tenant shall provide to Landlord
Tenant's and any guarantor's current financial statements, which Landlord shall
use solely for purposes of this Lease and in connection with the ownership,
management, financing and disposition of the Project. So long as Tenant is a
publicly traded company, Tenant may satisfy its obligations under this Paragraph
17 by delivering to Landlord Tenant's then current publicly available financial
statements.

                           18.  ESTOPPEL CERTIFICATE

Tenant agrees from time to time, within ten (10) days after request of Landlord,
to deliver to Landlord, or Landlord's designee, an estoppel certificate stating
that this Lease is in full force and effect, that this Lease has not been
modified (or stating all modifications, written or oral, to this Lease), the
date to which Rent has been paid, the unexpired portion of this Lease, that
there are no current defaults by Landlord or Tenant under this Lease (or
specifying any such defaults), that the leasehold estate granted by this Lease
is the sole interest of Tenant in the Premises and/or the land at which the
Premises are situated, and such other matters pertaining to this Lease as may be
reasonably requested by Landlord or any mortgagee, beneficiary, purchaser or
prospective purchaser of the Building or Project or any interest therein.
Failure by Tenant to execute and deliver such certificate shall constitute an
acceptance of the Premises and acknowledgment by Tenant that the statements
included are true and correct without exception. Tenant agrees that if Tenant
fails to execute and deliver such certificate within such ten (10) day period,
Landlord may execute and deliver such certificate on Tenant's behalf and that
such certificate shall be binding on Tenant. Landlord and Tenant intend that any
statement delivered pursuant to this Paragraph may be relied upon by any
mortgagee, beneficiary, purchaser or prospective purchaser of the Building or
Project or any interest therein. The parties agree that Tenant's obligation to
furnish such estoppel certificates in a timely fashion is a material inducement
for Landlord's execution of this Lease, and shall be an event of default
<PAGE>
with a cure period of ten (10) days after written notice of such failure) if
Tenant fails to fully comply or makes any material misstatement in any such
certificate.

                             19.  SECURITY DEPOSIT

Tenant agrees to deposit with Landlord upon execution of this Lease, a security
deposit as stated in the Basic Lease Information (the "SECURITY DEPOSIT"), which
sum shall be held and owned by Landlord, without obligation to pay interest, as
security for the performance of Tenant's covenants and obligations under this
Lease. The Security Deposit is not an advance rental deposit or a measure of
damages incurred by Landlord in case of Tenant's default. Upon the occurrence of
any event of default by Tenant, Landlord may from time to time, without
prejudice to any other remedy provided herein or by law, use such fund as a
credit to the extent necessary to credit against any arrears of Rent or other
payments due to Landlord hereunder, and any other damage, injury, expense or
liability caused by such event of default, and Tenant shall pay to Landlord, on
demand, the amount so applied in order to restore the Security deposit to its
original amount. Although the Security deposit shall be deemed the property of
Landlord, any remaining balance of such deposit shall be returned by Landlord to
Tenant at such time after termination of this Lease that all of Tenant's
obligations under this Lease have been fulfilled, reduced by such amounts as may
be required by Landlord to remedy defaults on the part of Tenant in the payment
of Rent or other obligations of Tenant under the Lease, to repair damage to the
Premises, Building or Project caused by Tenant or any Tenant's Parties and to
clean the Premises. Landlord may use and commingle the Security Deposit with
other funds of Landlord.

                      20.  LIMITATION OF TENANT'S REMEDIES

The obligations and liability of Landlord to Tenant for any default by Landlord
under the terms of this Lease are not personal obligations of Landlord or of the
individual or other partners of Landlord or its or their partners, directors,
officers, or shareholders, and Tenant agrees to look solely to Landlord's
interest in the Project for the recovery of any amount from Landlord, and shall
not look to other assets of Landlord nor seek recourse against the assets of the
individual or other partners of Landlord or its or their partners, directors,
officers or shareholders. Any lien obtained to enforce any such judgment and any
levy of execution thereon shall be subject and subordinate to any lien, mortgage
or deed of trust on the Project. Under no circumstances shall Tenant have the
right to offset against or recoup Rent or other payments due and to become due
to Landlord hereunder except as expressly provided in Paragraph 23.B. below,
which Rent and other payments shall be absolutely due and payable hereunder in
accordance with the terms hereof.

                         21.  ASSIGNMENT AND SUBLETTING

A.    (1)   GENERAL. This Lease has been negotiated to be and is granted as an
      accommodation to Tenant. Accordingly, this Lease is personal to Tenant,
      and Tenant's rights granted hereunder do not include the right to assign
      this Lease or sublease the Premises, or to receive any excess, either in
      installments or lump sum, over the Rent which is expressly reserved by
      Landlord as hereinafter provided, except as otherwise expressly
      hereinafter provided. Tenant shall not assign or pledge this Lease or
      sublet the Premises or any part thereof, whether voluntarily or by
      operation of law, or permit the use or occupancy of the Premises or any
      part thereof by anyone other than Tenant, or suffer or permit any such
      assignment, pledge, subleasing or occupancy, without Landlord's prior
      written consent except as provided herein. If Tenant desires to assign
      this Lease or sublet any or all of the Premises, Tenant shall give
      Landlord written notice (the "TRANSFER NOTICE") at least sixty (60) days
      prior to the anticipated effective date of the proposed assignment or
      sublease, which shall contain all of the information reasonably requested
      by Landlord to address Landlord's decision criteria specified hereinafter.
      Landlord shall then have a period of thirty (30) days following receipt of
      the Transfer Notice to notify Tenant in writing that Landlord elects
      either: (i) to terminate the Lease as to the space so affected as of the
      date so requested by Tenant so long as said space is more than 25% of the
      Premises and is for the balance of the remaining Lease term; or (ii) to
      consent to the proposed assignment or sublease, subject, however, to
      Landlord's prior written consent of the proposed assignee or subtenant and
      of any related documents or agreements associated with the assignment or
      sublease. If Landlord should fail to notify Tenant in writing of such
      election within said period, Landlord shall be deemed to have waived
      option (i) above, but written consent by Landlord of the proposed assignee
      or subtenant shall still be required. If Landlord does not exercise option
      (i) above, Landlord's consent to a proposed assignment or sublease shall
      not be unreasonably withheld, conditioned or delayed. Consent to any
      assignment or subletting shall not constitute consent to any subsequent
      transaction to which this Paragraph 21 applies.

      (2)   CONDITIONS OF LANDLORD'S CONSENT. Without limiting the other
      instances in which it may reasonable for Landlord to withhold Landlord's
      consent to an assignment or subletting, Landlord and Tenant acknowledge
      that it shall be reasonable for Landlord to withhold Landlord's consent in
      the following instances: if the proposed assignee does not agree to be
      bound by and assume the obligations of Tenant under this Lease in form and
      substance reasonably satisfactory to Landlord; the use of the Premises by
      such proposed assignee or subtenant would not be a Permitted Use or would
      violate any exclusivity or other arrangement which Landlord has with any
      other tenant or occupant or any Regulation or would increase the Occupancy
      Density or Parking Density permitted under this Lease, or would otherwise
      result in an undesirable tenant mix for the Project as determined by
      Landlord; the proposed assignee or subtenant is not of sound financial
      condition as determined by Landlord in Landlord's reasonable discretion;
      the proposed assignee or subtenant is a governmental agency; the proposed
      assignee or subtenant does not have a good reputation as a tenant of
      property or a good business reputation; the proposed assignee or subtenant
      is a person with whom Landlord is negotiating to lease space in the
      Project or is a present tenant of the Project; the assignment or
      subletting would entail any Alterations which would lessen the value of
      the leasehold improvements in the Premises or use of any Hazardous
      Materials or other noxious use or use which may disturb other tenants of
      the Project; or Tenant is in default of any obligation of Tenant under
      this Lease, or Tenant has defaulted under this Lease on three (3) or more
      occasions during any twelve (12) months preceding the date that Tenant
      shall request consent. Failure by or refusal of Landlord to consent to a
      proposed assignee or subtenant shall not cause a termination of this
      Lease. Upon a termination under Paragraph 21.A.(1)(i), Landlord may lease
      the Premises to any party, including parties with whom Tenant has
      negotiated an assignment or sublease, without incurring any liability to
      Tenant. At the option of Landlord, a surrender and termination of this
      Lease shall operate as an assignment to Landlord of some or all subleases
      or subtenancies. Landlord shall exercise this option by giving notice of
      that assignment to such subtenants on or before the effective date of the
      surrender and termination. In connection with each request for assignment
      or subletting, Tenant shall pay to Landlord Landlord's stand fee for
      approving such requests, as well as all costs incurred by Landlord or any
      mortgagee or ground lessor in approving each such request and effecting
      any such transfer, including, without limitation, reasonable attorneys'
      fees.

      (3)   PERMITTED TRANSFERS. An "Affiliate" means any entity that (i)
      controls, is controlled by, or is under common control with Tenant, (ii)
      results from the transfer of all or substantially all of Tenant's assets
      or stock, or (iii) results from the merger or consolidation of Tenant with
      another entity. "Control" means the direct or indirect ownership of more
      than fifty percent (50%) of the voting securities of an entity or
      possession of the right to vote more than fifty percent (50%) of the
      voting interest in the ordinary direction of the entity's affairs.
      Notwithstanding anything to the contrary contained in this Lease,
      Landlord's consent is not required for any assignment of this Lease or
      sublease of all or a portion of the Premises to an Affiliate so long as
      the following conditions are met: (a) at least ten (10) business days
      before any such assignment or sublease, Landlord receives written notice
      of such assignment or sublease (as well as any documents or information
      reasonably requested by Landlord
<PAGE>

        regarding the proposed intended transfer and the transferee; (b) no
        uncured Event of Default by Tenant exists under this Lease; (c) if the
        transfer is an assignment or any other transfer to an Affiliate other
        than a sublease, the intended assignee assumes in writing all of
        Tenant's obligations under this Lease relating to the Premises in form
        reasonably satisfactory to Landlord or, if the transfer is a sublease,
        the intended sublessee accepts the sublease in form reasonably
        satisfactory to Landlord; (d) the intended transferee has a tangible net
        worth, as evidenced by financial statements delivered to Landlord and
        certified by an independent certified public accountant in accordance
        with generally accepted accounting principles that are consistently
        applied, at least equal to Three Million Dollars ($3,000,000.00); (e)
        the Premises shall continue to be operated solely for the use specified
        in the Basic Lease Information; and (f) Tenant shall pay to Landlord all
        costs reasonably incurred by Landlord or any mortgagee or ground lessor
        for such assignment or subletting, including, without limitation,
        reasonable attorneys' fees. No transfer to an Affiliate in accordance
        with this subparagraph shall relieve Tenant named herein of any
        obligation under this Lease or alter the primary liability of Tenant
        named herein for the payment or Rent or for the performance of any other
        obligation to be performed by Tenant, including the obligations
        contained in Paragraph 25 with respect to any Affiliate.

        Notwithstanding anything to the contrary in this Lease, the transfer of
        outstanding capital stock or other listed equity interests of the
        purchase of outstanding capital stock or other listed equity interests,
        or the purchase of equity interests issued in an initial public offering
        of stock, by persons or parties other than "insiders" within the meaning
        of the Securities Exchange Act of 1934, as amended, through the
        "over-the-counter" market or any recognized national or international
        securities exchange shall not be included in determining whether control
        has been transferred.

B.      BONUS RENT. Any Rent or other consideration realized by Tenant under any
such sublease or assignment in excess of the Rent payable hereunder, after
amortization of a reasonable brokerage commission and Building Standard tenant
improvements including reasonable architectural fees for final construction
drawings incurred by Tenant, shall be divided and paid, ten percent (10%)
twenty-five percent (25%) to Tenant, Seventy-five percent (75%) to Landlord. In
any subletting or assignment undertaken by Tenant, Tenant shall diligently seek
to obtain the maximum rental amount available in the marketplace for comparable
space available for primary leasing.

C.      CORPORATION. If Tenant is a corporation, a transfer of corporate shares
by sale, assignment, bequest, inheritance, operation of law or other disposition
(including such a transfer to or by a receiver or trustee in federal or state
bankruptcy, insolvency or other proceedings) resulting in a change in the
present control of such corporation or any of its parent corporations by the
person or persons owning a majority of said corporate shares, shall constitute
an assignment for purposes of this Lease.

D.      UNINCORPORATED ENTITY.  If Tenant is a partnership, joint venture,
unincorporated limited liability company or other unincorporated business form,
a transfer of the interest of persons, firms or entities responsible for
managerial control of Tenant by sale, assignment, bequest, inheritance,
operation of law or other disposition, so as to result in a change in the
present control of said entity and/or of the underlying beneficial interests of
said entity and/or a change in the identity of the persons responsible for the
general credit obligations of said entity shall constitute an assignment for all
purposes of this Lease.

E.      LIABILITY.  No assignment or subletting by Tenant, permitted or
otherwise, shall relieve Tenant of any obligation under this Lease or alter the
primary liability of the Tenant named herein for the payment of Rent or for the
performance of any other obligations to be performed by Tenant, including
obligations contained in Paragraph 25 with respect to any assignee or subtenant.
Landlord may collect rent or other amounts or any portion thereof from any
assignee, subtenant, or other occupant of the Premises, permitted or otherwise,
and apply the net rent collected to the Rent payable hereunder, but no such
collection shall be deemed to be a waiver of this Paragraph 21, or the
acceptance of the assignee, subtenant or occupant as tenant, or a release of
Tenant from the further performance by Tenant of the obligations of Tenant under
this Lease. Any assignment or subletting which conflicts with the provisions
hereof shall be void.

                                22.   AUTHORITY

Landlord represents and warrants that it has full right and authority to enter
into this Lease and to perform all of Landlord's obligations hereunder and that
all persons signing this Lease on its behalf are authorized to do. Tenant
represents and warrants that Tenant has full right and authority to enter into
this Lease, and to perform all of Tenant's obligations hereunder, and that all
persons signing this Lease on its behalf are authorized to do so.

                               23.   CONDEMNATION

A.      CONDEMNATION RESULTING IN TERMINATION. If the whole or any substantial
part of the Premises should be taken or condemned for any public use under any
Regulation, or by right of eminent domain, or by private purchase in lieu
thereof, either party shall have the right to terminate this Lease at its
option If any material portion of the Building or Project is taken or condemned
for any public use under any Regulation, or by right of eminent domain, or by
private purchase in lieu thereof, Landlord may terminate this Lease at its
option. In either of such events, the Rent shall be abated during the unexpired
portion of this Lease, effective when the physical taking of said Premises
shall have occurred.

B.       CONDEMNATION NOT RESULTING IN TERMINATION. If a portion of the Project
of which the Premises are a part should be taken or condemned for any public use
under any Regulation, or by right of eminent domain, or by private purchase in
lieu thereof, and the taking prevents or materially interferes with the
Permitted Use of the Premises, and this Lease is not terminated as provided in
Paragraph 23.A above, the Rent payable hereunder during the unexpired portion of
this Lease shall be reduced, beginning on the date when the physical taking
shall have occurred, to such amount as may be fair and reasonable under all of
the circumstances, but only after giving Landlord credit for all sums received
or to be received by Tenant by the condemning authority. Notwithstanding
anything to the contrary contained in this Paragraph, if the temporary use or
occupancy of any part of the Premises shall be taken or appropriated under power
of eminent domain during the Term, this Lease shall be and remain unaffected by
such taking or appropriation and Tenant shall continue to pay in full all Rent
payable hereunder by Tenant during the Term; in the event of any such temporary
appropriation or taking, Tenant shall be entitled to receive that portion of any
award which represents compensation for the use of or occupancy of the Premises
during the Term, and Landlord shall be entitled to receive that portion of any
award which represents the cost of restoration of the Premises and the use and

<PAGE>

against Landlord or otherwise for any sums paid by virtue of such proceedings,
whether or not attributable to the value of any unexpired portion of this Lease,
except as expressly provided in this Lease. Notwithstanding the foregoing, any
compensation specifically and separately awarded Tenant for Tenant's personal
property and moving costs, shall be and remain the property of Tenant.

D.      WAIVER OF CCP SECTION 1265.130. Each party waives the provisions of
California Civil Code Procedure Section 1265.130 allowing either party to
petition the superior court to terminate this Lease as a result of a partial
taking.
<PAGE>
A.        GENERAL.  If the Premises or Building should be damaged or destroyed
by fire, tornado, or other casualty (collectively, "CASUALTY"), Tenant shall
give immediate written notice thereof to Landlord. Within thirty (30) days
after Landlord's receipt of such notice, Landlord shall notify Tenant whether
in Landlord's estimation material restoration of the Premises can reasonably be
made within one hundred eighty (180) days from the date of such notice and
receipt of required permits for such restoration or within two hundred seventy
(270) days from the date of such notice.  Landlord's reasonable determination
shall be binding on Tenant.

B.        WITHIN 180 DAYS. If the Premises or Building should be damaged by
Casualty to such extent that material restoration can in Landlord's estimation
be reasonably completed within one hundred eighty (180) days after the date of
such notice and receipt of required permits for such restoration, this Lease
shall not terminate. Provided that insurance proceeds are received by Landlord
to fully repair the damage, Landlord shall proceed to rebuild and repair the
Premises in the manner determined by Landlord, except that Landlord shall not
be required to rebuild, repair or replace any part of the Alterations which may
have been placed on or about the Premises by Tenant. If the Premises are
untenantable in whole or in part following such damage, the Rent payable
hereunder during the period in which they are untenantable shall be abated
proportionately, but only to the extent the Premises are unfit for occupancy.
As of the date of this Lease, Landlord currently carries rent abatement
insurance coverage.

C.        GREATER THAN 180 DAYS.  If the Premises or Building should be damaged
by Casualty to such extent that rebuilding or repairs cannot in Landlord's
estimation be reasonably completed within one hundred eighty (180) days after
the date of such notice and receipt of required permits for such rebuilding or
repair, then Landlord shall have the option of either: (1) terminating this
Lease effective upon the date of the occurrence of such damage, in which event
the Rent shall be abated during the unexpired portion of this Lease; or (2)
electing to rebuild or repair the Premises diligently and in the manner
determined by Landlord. Landlord shall notify Tenant of its election within
thirty (30) days after Landlord's receipt of notice of the damage or
destruction. Notwithstanding the above, Landlord shall not be required to
rebuild, repair or replace any part of any Alterations which may have been
placed, on or about the Premises by Tenant. If the Premises are untenantable in
whole or in part following such damage, the Rent payable hereunder during the
period in which they are untenantable shall be abated proportionately, but only
to the extent the Premises are unfit for occupancy.

D.        GREATER THAN 270 DAYS.  If the Premises or Building should be damaged
by Casualty to such extent that rebuilding or repairs cannot in Landlord's
estimation be reasonably completed within two hundred seventy (270) days after
receipt of such notice and such damage materially and adversely interferes with
the conduct of Tenant's business in the Premises, then either party shall have
the right to cancel this Lease by giving the other party written notice within
ten (10) days from the date of Landlord's notice that material restoration of
the Premises cannot be made within such two hundred seventy (270) day period or
notice that Landlord has elected not to rebuild or repair the Premises.
Further, if such damage is not substantially repaired within said two hundred
seventy (270) day period, Tenant may terminate this Lease by giving Landlord
written notice of such termination within ten (10) days following such two
hundred seventieth (270th) day.  Said cancellation shall be effective thirty
(30) days from the first day that either party gives its notice to cancel. If
neither party elects to so cancel this Lease, Landlord shall proceed to rebuild
and repair the Premises diligently and in the manner determined by Landlord,
except that Landlord shall not be required to rebuild, repair or replace any
part of any Alterations which may have been placed on or about the Premises by
Tenant.  If the Premises are untenantable in whole or in part following such
damage, the Rent payable hereunder during the period in which they are
untenantable shall be abated proportionately, but only to the extent the
Premises are unfit for occupancy.

E.      TENANT'S FAULT.  Notwithstanding anything herein to the contrary, if the
Premises or any other portion of the Building are damaged by Casualty resulting
from the fault, gross negligence, willful misconduct, or breach of this Lease by
Tenant or any of Tenant's Parties, Base Rent and Additional Rent shall not be
diminished during the repair the repair of such damage and Tenant shall be
liable to Landlord for the cost and expense of the repair and restoration of the
Building caused thereby to the extent such cost and expense is not covered by
insurance proceeds.

F.      INSURANCE PROCEEDS.  Notwithstanding anything herein to the contrary, if
the Premises or Building are damaged or destroyed and are not fully covered by
the insurance proceeds received by Landlord or if the holder of any indebtedness
secured by a mortgage or deed of trust covering the Premises requires that the
insurance proceeds be applied to such indebtedness, then in either case Landlord
shall have the right to terminate this Lease by delivering written notice of
termination to Tenant within thirty (30) days after the date of notice to
Landlord that said damage or destruction is not fully covered by insurance or
such requirement is made by any such holder, as the case may be, whereupon this
Lease shall terminate. For purposes of this Paragraph 24, insurance proceeds
shall include deductible amounts associated therewith, provided, however, that
such amounts may be deemed Operating Expenses in accordance with Paragraph 7
hereof.

G.      WAIVER.  This Paragraph 24 shall be Tenant's sole and exclusive remedy
in the event of damage or destruction to the Premises or the Building. As a
material inducement to Landlord entering into this Lease, Tenant hereby waives
any rights it may have under Sections 1932, 1933(4), 1941 or 1942 of the Civil
Code of California with respect to any destruction of the Premises. Landlord's
obligation for tenantability of the Premises and Tenant's right to make repairs
and deduct the expenses of such repairs, or under any similar law, statute or
ordinance now or hereafter in effect.

H.      TENANT'S PERSONAL PROPERTY.  In the event of any damage or destruction
of the Premises or the Building, under no circumstances shall Landlord be
required to repair any injury or damage to, or make any repairs to or
replacements of, Tenant's personal property.

                              25.    HOLDING OVER

Unless Landlord expressly consents in writing to Tenant's holding over, Tenant
shall be unlawfully and illegally in possession of the Premises, whether or not
Landlord accepts any rent from Tenant or any other person while Tenant remains
in possession of the Premises without Landlord's written consent.  If tenant
shall retain possession of the Premises or any portion thereof without
Landlord's consent following the expiration of this Lease or sooner termination
for any reason, then Tenant shall pay to Landlord for each day of such
retention double the amount of daily rental as of the last month prior to the
date of expiration or earlier termination. Tenant shall also indemnify, defend,
protect and hold Landlord harmless from any loss, liability or cost, including
consequential and incidental damages and reasonable attorneys' fees, incurred
by Landlord resulting from delay by Tenant in surrendering the Premises,
including, without limitation, any claims made by the succeeding tenant founded
on such delay. Acceptance of Rent by Landlord following expiration or earlier
termination of this Lease, or following demand by Landlord for possession of
the Premises, shall not constitute a renewal of this Lease, and nothing
contained in this Paragraph 25 shall waive Landlord's right of reentry or any
other right.  Additionally, if upon expiration or earlier termination of this
Lease, or following demand by Landlord for possession of the Premises, Tenant
has not fulfilled its obligation with respect to repairs and cleanup of the
Premises or any other Tenant obligations as set forth in this Lease, then
Landlord shall have the right to perform any such obligations as it deems
necessary at Tenant's sole cost and expense, and any time
<PAGE>

required by Landlord to complete such obligations shall be considered a period
of holding over and the terms of this Paragraph 25 shall apply. The provisions
of this Paragraph 25 shall survive any expiration or earlier termination of
this Lease.

                                 26.   DEFAULT

A.   EVENTS OF DEFAULT. The occurrence of any of the following shall constitute
an event of default (which may also be referred as an "Event of Default" or "in
default") on the part of Tenant:

     (1)  ABANDONMENT. Abandonment of the Premises for a continuous period in
     excess of thirty (30) days without prior written notice to Landlord from
     Tenant. Tenant waives any right to notice Tenant may have under Section
     1951.3 of the Civil Code of the State of California, the terms of this
     Paragraph 26.A. being deemed such notice to Tenant as required by said
     Section 1951.3.

     (2)  Failure to pay any installment of Rent or any other amount due and
     payable hereunder when said payment is due, such failure continuing for
     five (5) days after written notice of such failure, as to which time is of
     the essence, provided that Landlord shall not be required to provide such
     notice more than three times per twelve (12) month period commencing with
     the date of such notice, the fourth failure to pay any such amount within
     five (5) days after said payment is due during such 12-month period shall
     be an event of default hereunder without notice. Such notice shall replace
     rather than supplement any statutory notice required under Code of Civil
     Procedure Section 1161 or any similar or successor statute.

     (3)  OTHER OBLIGATIONS. Failure to perform any obligation, agreement or
     covenant under this Lease other than those matters specified in
     subparagraphs (1) and (2) of this Paragraph 26.A., such failure continuing
     for fifteen (15) business days after written notice of such failure, as to
     which time is of the essence provided that if such failure is not capable
     of being completed within such fifteen (15) business day period through no
     fault of Tenant, such failure shall not constitute an event of default
     hereunder so long as Tenant undertakes to cure the failure within such
     fifteen (15) business day period and thereafter diligently attempts to
     complete the cure as soon as reasonably possible, but the total aggregate
     cure period shall not exceed forty-five (45) calendar days.

     (4)  GENERAL ASSIGNMENT. A general assignment by Tenant for the benefit of
          creditors.

     (5)  BANKRUPTCY. The filing of any voluntary petition in bankruptcy by
     Tenant, or the filing of an involuntary petition by Tenant's creditors,
     which involuntary petition remains undischarged for a period of thirty
     (30) days. If under applicable law, the trustee in bankruptcy or Tenant has
     the right to affirm this Lease and continue to perform the obligations of
     Tenant hereunder, such trustee or Tenant shall, in such time period as may
     be permitted by the bankruptcy court having jurisdiction, cure all defaults
     of Tenant hereunder outstanding as of the date of the affirmance of this
     Lease and provide to Landlord such adequate assurances as may be necessary
     to ensure Landlord of the continued performance of Tenant's obligations
     under this Lease.

     (6)  RECEIVERSHIP. The employment of a receiver to take possession of
     substantially all of Tenant's assets or Tenant's leasehold of the Premises,
     if such appointment remains undismissed or undischarged for a period of
     thirty (30) days after the order therefor.

     (7)  ATTACHMENT. The attachment, execution or other judicial seizure of all
     or substantially all of Tenant's assets or Tenant's leasehold of the
     Premises, if such attachment or other seizure remains undismissed or
     undischarged for a period of thirty (30) days after the levy thereof.

     (8)  INSOLVENCY. The admission by Tenant in writing of its inability to pay
     its debts as they become due.

B.   REMEDIES UPON DEFAULT.

     (1)  TERMINATION. In the event of the occurrence of any event of default,
     Landlord shall have the right to give a written termination notice to
     Tenant, and on the date specified in such notice, Tenant's right to
     possession shall terminate, and this Lease shall terminate unless on or
     before such date all Rent in arrears and all costs and expenses incurred by
     or on behalf of Landlord hereunder shall have been paid by Tenant and all
     other events of default of this Lease by Tenant at the time existing shall
     have been fully remedied to the satisfaction of Landlord. At any time after
     such termination, Landlord may recover possession of the Premises or any
     part thereof and expel and remove therefrom Tenant and any other person
     occupying the same, including any subtenant or subtenants notwithstanding
     Landlord's consent to any sublease, by any lawful means, and again
     repossess and enjoy the Premises without prejudice to any of the remedies
     that Landlord may have under this Lease, or at law or equity by any reason
     of Tenant's default or of such termination. Landlord hereby reserves the
     right, but shall not have the obligation, to recognize the continued
     possession of any subTenant. The delivery or surrender to Landlord by or on
     behalf of Tenant of keys, entry codes, or other means to bypass security at
     the Premises shall not terminate this Lease.

     (2)  CONTINUATION AFTER DEFAULT. Even though an event of default may have
     occurred, this Lease shall continue in effect for so long as Landlord does
     not terminate Tenant's right to possession under Paragraph 26.B.(1) hereof,
     and Landlord may enforce all of Landlord's rights and remedies under this
     Lease and at law or in equity, including without limitation, the right to
     recover Rent as it becomes due, and Landlord, without terminating this
     Lease, may exercise all of the rights and remedies of a Landlord under
     Section 1951.4 of the Civil Code of the State of California or any
     successor code section. Acts of maintenance, preservation or efforts to
     lease the Premises or the appointment of a receiver under application of
     Landlord to protect Landlord's interest under this Lease or other entry by
     Landlord upon the Premises shall not constitute an election to terminate
     Tenant's right to possession.

     (3)  INCREASED SECURITY DEPOSIT. If Tenant is in default under Paragraph
     26.A.(2) hereof and such default remains uncured for ten (10) days after
     such occurrence or such default occurs more than three times in any twelve
     (12) month period, Landlord may require that Tenant increase the Security
     Deposit to the amount of two times the current month's Rent at the time of
     the most recent default.

C.   DAMAGES AFTER DEFAULT. Should Landlord terminate this Lease pursuant to the
provisions of Paragraph 26.B.(1) hereof, Landlord shall have the rights and
remedies of a Landlord provided by Section 1951.2 of the Civil Code of the State
of California, or any successor code sections. Upon such termination, in
addition to any other rights and remedies to which Landlord may be entitled
under applicable law or at equity, Landlord shall be entitled to recover from
Tenant: (1) the worth at the time of award of the unpaid Rent and other amounts
which had been earned at the time of termination, (2) the worth at the time of
award of the amount by which the unpaid Rent and other amounts that would have
been earned after the date of termination until the time of award exceeds the
amount of such Rent loss that Tenant proves could have been reasonably avoided;
(3) the worth at the time of award of the amount by which the unpaid Rent

<PAGE>
and other amounts for the balance of the Term after the time of award exceeds
the amount of such Rent loss that the Tenant proves could be reasonably avoided;
and (4) any other amount and court costs 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. The "worth at the time of award" as used in (1)
and (2) above shall be computed at the Applicable Interest Rate (defined below).
The "worth at the time of award" as used in (3) above shall be computed by
discounting such amount at the Federal Discount Rate of the Federal Reserve Bank
of San Francisco at the time of award plus one percent (1%).

D. LATE CHARGE. In addition to its other remedies, Landlord shall have the right
without notice or demand to add to the amount of any payment required to be made
by Tenant hereunder, and which is not paid and received by Landlord on or before
the first day of each calendar month, an amount equal to ten percent (10%) of
the delinquency for each month or portion thereof that the delinquency remains
outstanding to compensate Landlord for the loss of the use of the amount not
paid and the administrative costs caused by the delinquency, the parties
agreeing that Landlord's damage by virtue of such delinquencies would be
extremely difficult and impracticable to compute and the amount stated herein
represents a reasonable estimate thereof. Any waiver by Landlord of any late
charges or failure to claim the same shall not constitute a waiver of other late
charges or any other remedies available to Landlord.

E. INTEREST. Interest shall accrue on all sums not paid when due hereunder at
the lesser of twelve percent (12%) per annum or the maximum interest rate
allowed by law ("APPLICABLE INTEREST RATE") from the due date until paid.

F. REMEDIES CUMULATIVE. All rights, privileges and elections or remedies of the
parties are cumulative and not alternative, to the extent permitted by law and
except as otherwise provided herein.

                                   27. LIENS

Tenant shall at all times keep the Premises and the Project free from liens
arising out of or related to work or services performed, materials or supplies
furnished or obligations incurred by or on behalf of Tenant or in connection
with work made, suffered or done by or on behalf of Tenant in or on the Premises
or Project. If Tenant shall not, within thirty (30) 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
the same to be released by such means as Landlord shall deem proper, including
payment of the claim giving rise to such lien. All sums paid by Landlord on
behalf of Tenant and all expenses incurred by Landlord in connection therefor
shall be payable to Landlord by Tenant on demand with interest at the Applicable
Interest Rate as Additional Rent. Landlord shall have the right at all times to
post and keep posted on the Premises any notices permitted or required by law,
or which Landlord shall deem proper, for the protection of Landlord, the
Premises, the Project and any other party having an interest therein, from
mechanics' and materialmen's liens, and Tenant shall give Landlord not less than
ten (10) business days prior written notice of the commencement of any work in
the Premises or Project which could lawfully give rise to a claim for mechanics'
or materialmen's liens to permit Landlord to post and record a timely notice of
non-responsibility, as Landlord may elect to proceed or as the law may from time
to time provide, for which purpose, if Landlord shall so determine, Landlord may
enter the Premises. Tenant shall not remove any such notice posted by Landlord
without Landlord's consent, and in any event not before completion of the work
which could lawfully give rise to a claim for mechanics' or materialmen's liens.

                                28. SUBSTITUTION

A. At any time after execution of this Lease, Landlord may substitute for that
portion of the Premises located on the 8th Floor other premises in the Building
(the "NEW PREMISES") upon not less than sixty (60) days prior written notice, in
which event the New Premises shall be deemed to be the Premises for all purposes
hereunder and this Lease shall be deemed modified accordingly to reflect the new
location and shall remain in full force and effect as so modified, provided
that:

      (1) The New Premises shall be comparable in area (square footage,
      configuration) and in function for Tenant's purposes; and

      (2) If Tenant is occupying the Premises at the time of such substitution,
      Landlord shall pay all reasonable expense(s) of physically moving Tenant,
      Tenant's property and equipment to the New Premises, recabling Tenant's
      telecommunications and computer systems with like materials to existing
      and the cost of changing Tenant's stationery and business cards, if
      applicable. Landlord shall at Landlord's sole cost, improve the New
      Premises with improvements substantially similar to those existing in the
      8th Floor Premises.

                           29. TRANSFERS BY LANDLORD

In the event of a sale or conveyance by Landlord of the Building or a
foreclosure by any creditor of Landlord, the same shall operate to release
Landlord from any liability upon any of the covenants or conditions, express or
implied, herein contained in favor of Tenant, to the extent required to be
performed after the passing of title to Landlord's successor-in-interest. In
such event, Tenant agrees to look solely to the responsibility of the
successor-in-interest of Landlord under this Lease with respect to the
performance of the covenants and duties of "Landlord" to be performed after the
passing of title to Landlord's successor-in-interest. This Lease shall not be
affected by any such sale and Tenant agrees to attorn to the purchaser or
assignee. Landlord's successor(s)-in-interest shall not have liability to Tenant
with respect to the failure to perform any of the obligations of "Landlord," to
the extent required to be performed prior to the date such
successor(s)-in-interest became the owner of the Building.

              30. RIGHT OF LANDLORD TO PERFORM TENANT'S COVENANTS

All covenants and agreements to be performed by Tenant under any of the terms of
this Lease shall be performed by Tenant at Tenant's sole cost and expense and
without any abatement of Rent. If Tenant shall fail to pay any sum of money,
other than Base Rent, required to be paid by Tenant hereunder or shall fail to
perform any other act on Tenant's part to be performed hereunder, including
Tenant's obligations under Paragraph 11 hereof, and such failure shall continue
for fifteen (15) business days after notice thereof by Landlord, in addition to
the other rights and remedies of Landlord, Landlord may make any such payment
and perform any such act on Tenant's part. In the case of an emergency, no prior
notification by Landlord shall be required. Landlord amy take such actions
without any obligation and without releasing Tenant from any of Tenant's
obligations. All sums so paid by Landlord and all incidental costs incurred by
Landlord and interest thereon at the Applicable Interest Rate, from the date of
payment by Landlord, shall be paid to Landlord on demand as Additional Rent.

<PAGE>
                                   31. WAIVER

If either Landlord or Tenant waives the performance of any term, covenant or
condition contained in this Lease, such waiver shall not be deemed to be a
waiver of any subsequent breach of the same or any other term, covenant or
condition contained herein, or constitute a course of dealing contrary to the
expressed terms of this Lease. The acceptance of Rent by Landlord shall not
constitute a waiver of any preceding breach by Tenant of any term, covenant or
condition of this Lease, regardless of Landlord's knowledge of such preceding
breach at the time Landlord accepted such Rent. Failure by Landlord to enforce
any of the terms, covenants or conditions of this Lease for any length of time
shall not be deemed to waive or decrease the right of Landlord to insist
thereafter upon strict performance by Tenant. Waiver by Landlord of any term,
covenant or condition contained in this Lease may only be made by a written
document signed by Landlord, based upon full knowledge of the circumstances.

                                  32. NOTICES

Each provision of this Lease or of any applicable governmental laws, ordinances,
regulations and other requirements with reference to sending, mailing, or
delivery of any notice or the making of any payment by Landlord or Tenant to the
other shall be deemed to be complied with when and if the following steps are
taken:

A. RENT. All Rent and other payments required to be made by Tenant to Landlord
hereunder shall be payable to Landlord at Landlord's Remittance Address set
forth in the Basic Lease Information, or at such other address as Landlord may
specify from time to time by written notice delivered in accordance herewith.
Tenant's obligation to pay Rent and any other amounts to Landlord under the
terms of this Lease shall not be deemed satisfied until such Rent and other
amounts have been actually received by Landlord.

B. OTHER. All notices, demands, consents and approvals which may or are required
to be given by either party to the other hereunder shall be in writing and
either personally delivered, sent by commercial overnight courier, mailed,
certified or registered, postage prepaid or sent by facsimile with confirmed
receipt (and with an original sent by commercial overnight courier), and in each
case addressed to the party to be notified at the Notice Address for such party
as specified in the Basic Lease Information or to such other place as the party
to be notified may from time to time designate by at least fifteen (15) days
notice to the notifying party. Notices shall be deemed served upon receipt or
refusal to accept delivery. Tenant appoints as its agent to receive the service
of all default notices and notice of commencement of unlawful detainer
proceedings the person in charge of or apparently in charge of occupying the
Premises at the time, and, if there is no such person, then such service may be
made by attaching the same on the main entrance of the Premises, provided,
however, a copy of all such default notices and other services shall also be
sent to Tenant at Tenant's notice address in accordance with the requirements of
this Paragraph 32.

C. REQUIRED NOTICES. Tenant shall immediately notify Landlord in writing of any
notice received by Tenant of a violation or a potential or alleged violation of
any Regulation that relates to the Premises or the Project, or of any inquiry,
investigation, enforcement or other action that is instituted or threatened by
any governmental or regulatory agency against Tenant or any other occupant of
the Premises, or any claim that is instituted or threatened by any third party
that relates to the Premises or the Project.

                              33. ATTORNEYS' FEES

If Landlord places the enforcement of this Lease, or any part hereof, or the
collection of any Rent due, or to become due hereunder, or recovery of
possession of the Premises in the hands of an attorney, Tenant shall pay to
Landlord, upon demand, Landlord's reasonable attorneys' fees and court costs,
whether incurred without trial, at trial, appeal or review. In any action which
Landlord or Tenant brings to enforce its respective rights hereunder, the
unsuccessful party shall pay all costs incurred by the prevailing party,
including reasonably attorneys' fees, to be fixed by the court, and said costs
and attorneys' fees shall be a part of the judgment in said action.

                           34. SUCCESSORS AND ASSIGNS

This Lease shall be binding upon and inure to the benefit of Landlord, its
successors and assigns, and shall be binding upon and inure to the benefit of
Tenant, its successors, and to the extent assignment is approved by Landlord as
provided hereunder, Tenant's assigns.

                               35. FORCE MAJEURE

If performance by a party of any portion of this Lease is made impossible by any
prevention, delay, or stoppage caused by strikes, lockouts, labor disputes, acts
of God, inability to obtain services, labor, or materials or reasonable
substitutes for those items, government actions, civil commotions, fire or other
casualty, or other causes beyond the reasonable control of the party obligated
to perform, performance by that party for a period equal to the period of that
prevention, delay, or stoppage is excused. Tenant's obligation to pay Rent,
however, is not excused by this Paragraph 35.

                           36. SURRENDER OF PREMISES

Tenant shall, upon expiration or sooner termination of this Lease, surrender the
Premises to Landlord in the same condition as existed on the date Tenant
originally took possession thereof, including, but not limited to, all interior
walls cleaned, all holes in walls repaired, all floors broom cleaned and in good
condition except for ordinary wear and tear and free of any unusual or
extra-ordinary Tenant-introduced marking or painting, all to the reasonable
satisfaction of Landlord. Tenant shall remove all of its debris from the
Project. At or before the time of surrender, Tenant shall comply with the terms
of Paragraph 12.A. hereof with respect to Alterations to the Premises and all
other matters addressed in such Paragraph. If the Premises are not so
surrendered at the expiration or sooner termination of this Lease, the
provisions of Paragraph 25 hereof shall apply. All keys to the Premises or any
part thereof shall be surrendered to Landlord upon expiration or sooner
termination of the Term. Tenant shall meet with Landlord for a joint inspection
of the Premises at the time of vacating, but nothing contained herein shall be
construed as an extension of the Term or as a consent by Landlord to any holding
over by Tenant. In the event of Tenant's failure to participate in such joint
inspection, Landlord's inspection at or after Tenant's vacating the Premises
shall conclusively be deemed correct for purposes of determining Tenant's
responsibility for repairs and restoration. Any delay caused by Tenant's failure
to carry out its obligations under this Paragraph 36 beyond the term hereof,
shall constitute unlawful and illegal possession of Premises under Paragraph 25
hereof.

                                  37. PARKING

        So long as Tenant and/or Tenant's Parties is/are occupying the Premises,
Tenant and Tenant's Parties shall have the right to use up to the number of
parking spaces, if any, specified in the Basic Lease Information on an
unreserved, nonexclusive, first come, first served basis, for passenger-size
automobiles, in the parking areas in the Project designated from time to time by
Landlord for use in common by tenants of the Building.

<PAGE>
    Tenant may request additional parking spaces from time to time and if
Landlord in its sole discretion agrees to make such additional spaces available
for use by Tenant, such spaces shall be provided on a month-to-month unreserved
and nonexclusive basis (unless otherwise agreed in writing by Landlord), and
subject to such parking charges as Landlord shall determine, and shall otherwise
be subject to such terms and conditions as Landlord may require.

    Tenant shall at all times comply and shall cause all Tenant's Parties and
visitors to comply with all Regulations and any rules and regulations
established from time to time by Landlord relating to parking at the Project,
including any keycard, sticker or other identification or entrance system, and
hours of operation, as applicable.

    Except to the extent such damage or liability is caused by the gross
negligence or willful misconduct of Landlord, Landlord's agents, employees or
representatives, Landlord shall have no liability for any damage to property or
other items located in the parking areas of the Project, nor for any personal
injuries or death arising out of the use of parking areas in the Project by
Tenant or any Tenant's Parties. Without limiting the foregoing, if Landlord
arranges for the parking areas to be operated by an independent contractor not
affiliated with Landlord, Tenant acknowledges that Landlord shall have no
liability for claims arising through acts or omissions of such independent
contractor. In all events, Tenant agrees to look first to its insurance carrier
and to require that Tenant's Parties look first to their respective insurance
carriers for payment of any losses sustained in connection with any use of the
parking areas.

    Landlord reserves the right to assign specific spaces, and to reserve spaces
for visitors, small cars, disabled persons or for other tenants or guests, and
Tenant shall not park and shall not allow Tenant's Parties to park in any such
assigned or reserved spaces. Tenant may validate visitor parking by such method
as Landlord may approve, at the validation rate from time to time generally
applicable to visitor parking. Landlord also reserves the right to alter,
modify, relocate or close all or any portion of the parking areas in order to
make repairs or perform maintenance service, or to restripe or renovate the
parking areas, or if required by casualty, condemnation, act of God, Regulations
or for any other reason deemed reasonable by Landlord provided, however, such
alteration, modification or relocation shall not materially decrease the number
of spaces or have a material adverse effect on Tenant's use.

    Tenant shall pay to Landlord (or Landlord's parking contractor, if so
directed in writing by Landlord), as Additional Rent hereunder, the monthly
charges established from time to time by Landlord for parking in such parking
areas (which shall initially be the charge specified in the Basic Lease
Information, as applicable). Such parking charges shall be payable in advance
with Tenant's payment of Basic Rent. No deductions from the monthly parking
charge shall be made for days on which the Tenant does not use any of the
parking spaces entitled to be used by Tenant. Notwithstanding anything to the
contrary, Tenant's employees actually employed at the Premises shall not be
charged for daily parking in the allotted number of parking spaces pursuant to
this Lease during the initial six (6) year term of the Lease, however, Landlord
reserves the right to assess a parking fee to any of Tenant's employees who,
from time to time, leaves their vehicles in the parking area for any extended
period of time.

                               38. MISCELLANEOUS

footage of the Premises, rentable, usable or otherwise, and no recalculation, if

this Lease in any manner, including without limitation the amount of Base Rent
payable by Tenant or Tenant's Proportionate Share of the Building and of the

Project pursuant to a ground lease (the "GROUND LEASE") under which Landlord is
the lessee and Metro Center Tower, LLC ("GROUND LESSOR") is the lessor. Tenant
further acknowledges that this Lease is subject and subordinate to the Ground
Lease; provided however, Tenant shall be entitled to the benefits and
protections set forth in Section 12.4 of the Ground Lease. Tenant hereby agrees
it shall not take any action which would constitute a violation of the Ground
Lease. Landlord represents to Tenant that this Lease is not prohibited by and

that Ground Lessor succeeds to the interest of Landlord under this Lease, Tenant
agrees, at the written request of Ground Lessor, to attorn to Ground Lessor or

Tenant shall, provided this Lease is in full force and effect, that no uncured
Event of Default exists under any of the terms and conditions of this Lease and
Tenant has not been in default more than three (3) times over the initial term
of the Lease, Tenant shall have one (1) successive option to renew this Lease
for a term of five (5) years, for the Premises in an "as is" condition and on
the same terms and conditions set forth in this Lease, except as modified by the
terms, covenants and conditions set forth below:

     (1)  If Tenant elects to exercise such option, then Tenant shall provide
          Landlord with written notice twelve (12) months prior to the
          expiration of the then current term of this Lease. If Tenant fails to
          provide such notice, Tenant shall have no further or additional right
          to extend or renew the term of this Lease.

     (2)  The Base Rent in effect at the expiration of the then current term of
          this Lease shall be amended to reflect the current fair market rental
          for comparable space in the Building or Project and in other similar
          buildings in the San Mateo/Foster City/Redwood Shores area as of the
          date the renewal term is to commence, taking into account the specific
          provisions of this Lease which will remain constant, and the Building
          amenities, location, identity, quality, age, conditions, term of
          lease, tenant improvements, services provided, and other pertinent
          items.

     (3)  Landlord shall advise Tenant of the new Base Rent for the Premises for
          the applicable renewal term which will be based on Landlord's
          reasonable determination of fair market rental value, as well as
          additional terms and conditions for the renewal term, no later than
          fifteen (15) business days after receipt of notice of Tenant's
          exercise of its option to

<PAGE>
          renew. Tenant shall have forty-five (45) days after receipt of such
          notification from Landlord to accept the new Base Rent, terms and
          conditions. If Tenant does not accept Landlord's determination of the
          new Base Rent, terms and conditions within such forty-five (45) day
          period, this option shall be null and void, and Landlord shall have no
          further obligation to Tenant and may enter into a lease for the
          Premises with a third party on such terms and conditions as Landlord
          may determine in its sole discretion.

     (4)  Notwithstanding anything to the contrary contained in this Paragraph,
          Landlord shall have no obligation to provide or pay for any tenant
          improvements or brokerage commissions during any renewal term.

     (5)  Tenant's right to exercise the option to renew under this Paragraph
          shall be conditioned upon Tenant occupying the entire Premises and the
          same not being occupied by any assignee, subtenant or licensee other
          than Tenant or its affiliate at the time of exercise of any option and
          commencement of the renewal term. Tenant's exercise of any option to
          renew shall constitute a representation by Tenant to Landlord that as
          of the date of exercise of the option and the commencement of the
          applicable renewal term, Tenant does not intend to seek to assign this
          Lease in whole or in part, or sublet all or any portion of the
          Premises.

     (6)  Any exercise by Tenant of any option to renew under this Paragraph
          shall be irrevocable. If requested by Landlord, Tenant agrees to
          execute a lease amendment reflecting the foregoing terms and
          conditions, prior to the commencement of the renewal term. The option
          to renew granted under this Paragraph is not transferable; the parties
          hereto acknowledge and agree that they intend that each option to
          renew this Lease under this Paragraph shall be "personal" to the
          specific Tenant named in this Lease and that in no event will any
          assignee or sublessee have any rights to exercise such option to
          renew.

     (7)  Notwithstanding anything to the contrary contained herein, reference
          made within this Paragraph 41 to Tenant shall mean Tenant and Tenant's
          Affiliates as provided under Paragraph 21.A(3) Permitted Transfers
          except it shall not include sublease Affiliates.

                           42.  RIGHT OF FIRST OFFER

Provided that no uncured Event of Default exists of any terms and conditions of
this Lease, Tenant shall have a right of first offer to lease the following: a)
approximately 5,190 square feet ("Suite 300") and approximately 2,263 square
feet ("Suite 340") on the 3rd floor of the building as shown on Exhibits D-1 and
D-2 and (b) approximately 8,175 square feet (Suite "450") on the 4th floor of
the building as shown in Exhibit D-3 to the extent that Suite 450 is not used by
Landlord for Landlord's offices, Building Amenities or Common Area at such time
as such additional space is vacated by the prior tenant. Upon notification by
Landlord in writing of the availability of space and the terms and conditions on
which Landlord is willing to lease such additional space to Tenant, Tenant shall
have five (5) business days to notify Landlord in writing of Tenant's desire to
exercise Tenant's right of first offer on the terms and conditions. In the event
Tenant fails to give Landlord notice of Tenant's election to lease such
additional space within such time period, Tenant shall have no further right,
title or interest in such additional space and this right of first offer shall
terminate. If, on the other hand, Tenant exercises its right of first offer in
the manner prescribed, Tenant shall immediately deliver to Landlord payment for
the first month's rent for such additional space (in the same manner as provided
for in this Lease), and the lease amendment for such additional space shall be
consummated without delay in accordance with the terms and conditions set forth
in Landlord's notice. Such additional space shall be leased to Tenant on an "as
is" basis and Landlord shall have no obligation to improve such additional space
or grant Tenant any improvement allowance thereon. Notwithstanding anything to
the contrary herein contained, Tenant's right to the expansion premises shall be
conditioned upon the following: (i) at the time Tenant agrees to accept the
expansion premises and at the time of the commencement of the term for the
expansion premises, Tenant shall be in possession of and occupying the primary
premises for the conduct of its business therein and the same shall not be
occupied by any assignee, subtenant or licensee and, provided further, that the
option for additional space shall be applicable hereunder only if the expansion
premises will actually be occupied by Tenant and (ii) the agreement of
acceptance shall constitute a representation by Tenant to Landlord, effective as
of the date of the agreement of acceptance and as of the date of commencement of
the lease for the expansion premises, that Tenant does not intend to assign the
lease for the expansion premises, in whole or in part or sublet all or any
portion of the Premises, the election to expand being for the purpose of
utilizing the expansion premises for Tenant's purposes in the conduct of
Tenant's business therein. Notwithstanding anything to the contrary contained
herein, reference made within this Paragraph 42 to Tenant shall mean Tenant and
Tenant's Affiliates as provided under Paragraph 21.A(3) Permitted Transfers
except it shall not include sublease Affiliates.

                             43.  EARLY POSSESSION

Upon full execution of this Lease, Tenant shall have the right to take
possession of the 5th floor Premises ("Suite 500") on or about March 1, 2000 for

Expenses.

                            44.  TENANT IMPROVEMENT

Tenant accepts the Premises in its "as it" condition and acknowledges that it
has had an opportunity to inspect the Premises prior to signing the Lease.
Landlord shall provide a Tenant Improvement Allowance ("Tenant Improvement
Allowance") of One Hundred Twenty Five Thousand Dollars ($125,000.00) to be used
toward the total cost of design, engineering, city and other agency fees, and
construction cost for the tenant improvements ("Tenant Improvements"), including
carpet, paint, and other minor construction. Said improvements are to be
determined and mutually agreed upon by Landlord and Tenant. Tenant shall be
responsible for any Tenant Improvements exceeding Landlord's contribution.

Should said Tenant Improvements be less than $125,000.00, Landlord will be
obligated for only those amounts expended. The tenant improvement allowance
shall be applicable only to costs incurred and work performed within 120 days
from the Term Commencement Date.

Landlord and/or Tenant shall retain the services of the space planner/architect

construction of the tenant improvements (the "Plans") mutually satisfactory to
Landlord and Tenant for the construction of the Tenant Improvements in the
Premises. Landlord shall have no responsibility or liability whatsoever for any
errors or omissions contained in the Space Plan or Plans, or to verify
dimensions or

<PAGE>
conditions, or for the quality, design or compliance with applicable Regulation
of any improvements described therein or constructed in accordance therewith.

Specifications and quantities of standard building components which will
comprise and be used in the construction of the Tenant Improvements
("Standards") are set forth in Exhibit C-Schedule 1.  As used herein,
"Standards" or "Building Standards" shall mean the standards for a particular
item selected from time to time by Landlord for the Building, including those
set forth on Exhibit C-Schedule 1, or such other standards of equal or better
quality as may be mutually agreed between Landlord and Tenant in writing.

Upon Tenant's approval of the Plans including the estimate of the cost of the
Tenant Improvements, and Landlord's and Tenant's agreement for payment of any
such estimated cost exceeding the amount of the Tenant Improvement Allowance,
Landlord shall cause a contractor, which contractor has been mutually agreed
upon by Landlord and Tenant, to proceed to secure a building permit and commence
construction of the Tenant Improvements provided that Tenant shall cooperate
with Landlord in executing permit applications and performing other actions
reasonably necessary to enable Landlord to obtain any required permits or
certificates of occupancy, and provided further that the Building has in
Landlord's discretion reached the stage of construction where it is appropriate
to commence construction of the Tenant Improvements in the Premises.

Landlord's administrative fee for the initial Tenant Improvements shall be
mutually agreed upon by Landlord and Tenant, however, such fee shall not exceed
five percent (5%) of such tenant improvement costs. Tenant and Landlord agree
that an administrative fee will not be charged on the initial Tenant
Improvement allowance of $125,000.00.

Landlord shall not be liable for any direct or indirect damages suffered by
Tenant as a result of delays in construction beyond Landlord's reasonable
control, including, but not limited to, delays due to strikes or unavailability
of materials or labor, on delays caused by tenant (including delays by the
Space Planner, the contractor or anyone else performing services on behalf of
Landlord or Tenant).

Promptly after substantial completion of the Tenant Improvements, Landlord and
Tenant shall conduct an inspection of the Premises to develop a punchlist of
items of the Tenant Improvements that are not complete or that require
corrections. Upon receipt of such punchlist, Landlord shall proceed diligently
to cause the contractor to remedy such items. Substantial completion shall not
be delayed notwithstanding delivery of any such punchlist.

In addition, with respect to the 5th floor Premises ("Suite 500"), Landlord
will provide those Premises to Tenant in a broom clean condition, and all
Building Systems shall be in good working order as of the Term Commencement
Date.

                                45.   OCCUPANCY

Tenant utilizes Suite 860 as a training center. Landlord's acknowledgement of
the use of Suite 860 as a training center is personal to Tenant and to any
Affiliate of Tenant which is a permitted asignee pursuant to Paragraph 21
above, and the acknowledgement hereunder shall be null and void upon any other
assignment or sublease of the Premises.

                           44.-46. JURY TRIAL WAIVER

EACH PARTY HERETO (WHICH INCLUDES ANY ASIGNEE,  SUCCESSOR HEIR OR PERSONAL
REPRESENTATIVE OF A PARTY) SHALL NOT SEEK A JURY TRIAL, HEREBY WAIVES TRIAL BY
JURY, AND HEREBY FURTHER WAIVES ANY OBJECTION TO VENUE IN THE COUNTY IN WHICH

LEASE OR ON TORT LAW.  EACH PARTY REPRESENTS THAT IT HAS HAD THE OPPORTUNITY TO
CONSULT WITH LEGAL COUNSEL CONCERNING THE EFFECT OF THIS PARAGRAPH 46. THE
PROVISIONS OF THIS PARAGRAPH 46 SHALL SURVIVE THE EXPIRATION OR EARLIER
TERMINATION OF THIS LEASE.

                             RULES AND REGULATIONS

1.   Driveways, sidewalks, halls, passages, exits, entrances, elevators,
     escalators and stairways shall not be obstructed by tenants or used by
     tenants for any purpose other than for ingress to and egress from their
     respective premises. The driveways, sidewalks, halls, passages, exits,
     entrances, elevators and stairways are not for the use of the general
     public and Landlord shall in all cases retain the right to control and
     prevent access thereto by all persons whose presence, in the judgment of
     Landlord, shall be prejudicial to the safety, character, reputation and
     interests of the Building, the Project and its tenants, provided that
     nothing herein contained shall be construed to prevent such access to
     persons with whom any tenant normally deals in the ordinary course of such
     tenant's business unless such persons are engaged in illegal activities.
     No tenant, and no employees or invitees of any tenant, shall go upon the
     roof of any Building, except as authorized by Landlord. No tenant, and no
     employees or invitees of any tenant shall move any common area furniture
     without Landlord's consent.

2.   No sign, placard, banner, picture, name, advertisement or notice, visible
     from the exterior of the Premises or the Building or the common areas of
     the Building shall be inscribed, painted, affixed, installed or otherwise
     displayed by Tenant either on its Premises or any part of the Building or
     Project without the prior written consent of Landlord in Landlord's sole
     and absolute reasonable discretion. Landlord shall have the right to
     remove any such sign, placard, banner, picture, name, advertisement, or
     notice without notice to and at the expense of Tenant, which were
     installed or displayed in violation of this rule. If Landlord shall have
     given such consent to Tenant at any time, whether before or after the
     execution of Tenant's Lease, such consent shall in no way operate as a
     waiver or release of any of the provisions hereof or of the Lease, and
     shall be deemed to relate only to the particular sign, placard, banner,
     picture, name, advertisement or notice so consented to by Landlord and
     shall not be construed as dispensing with the necessity of obtaining the
     specific written consent of Landlord with respect to any other such sign,
     placard, banner, picture, name, advertisement or notice.

     All approved signs or lettering on doors and walls shall be printed,
     painted, affixed or inscribed at the expense of Tenant by a person or
     vendor approved by Landlord and shall be removed by Tenant at the time of
     vacancy at Tenant's expense.

3.   The directory of the Building or Project will be provided exclusively for

     coverings, awnings, hangings or decorations shall be attached to, hung or

     Landlord's standard window covering and shall in no way be visible from
     the exterior of the Building. All electrical ceiling fixtures hung in
     offices or spaces along the perimeter of the Building must be fluorescent
     or of a quality, type, design, and bulb color approved by Landlord. No
     articles shall be placed or kept on the window sills so as to be visible
     from the exterior of the Building. No articles shall be placed against
     glass partitions or doors which Landlord considers unsightly from outside
     Tenant's Premises.

5.   Landlord reserves the right to exclude from the Building and the Project,
     between the hours of 6 p.m. and 8 a.m. and at all hours on Saturdays,
     Sundays and legal holidays, all persons who are not tenants or their
     accompanied guests in the Building. Each tenant shall be responsible for
     all persons for whom it allows to enter the Building or the Project and
     shall be liable to Landlord for all actions of such persons.

     Landlord and its agents shall not be liable for damages for any error
     concerning the admission to, or exclusion from, the Building or the
     Project of any person.

     During the continuance of any invasion, mob, riot, public excitement or
     other circumstance rendering such action advisable in Landlord's opinion,
     Landlord reserves the right (but shall not be obligated) to prevent access

     any means it considers appropriate for the safety of tenants and
     protection of the Building, property in the Building and the Project.

     Landlord shall be permitted to enter the Building for the purpose of
     cleaning the same. Tenant shall not cause any unnecessary labor by reason
     of Tenant's carelessness or indifference in the preservation of good order
     and cleanliness of its Premises. Landlord shall in no way be responsible

     for any damage done to Tenant's property by the janitor or any other
     employee or any other person.

     utilities shall likewise be carefully shut off, so as to prevent waste or
     damage. Tenant shall be responsible for any damage or injuries sustained
     by other tenants or occupants of the Building or Project or by Landlord
     for noncompliance with this rule. On multiple-tenancy floors, all tenants
     shall keep the door or doors to the Building corridors closed at all times
     except for ingress and egress.

     and shall refrain from attempting to adjust any controls other than room
     thermostats installed for Tenant's use.

     access device or bolt on any door of its Premises, without the prior
     written consent of Landlord. If Landlord shall give its consent, Tenant
     shall in each case furnish Landlord with a key for any such lock. Tenant,
     upon the termination of its tenancy, shall deliver to Landlord the keys
     for all doors which have been furnished to Tenant and in the event of loss
     of any keys so furnished, shall pay Landlord therefor.

10.  The restrooms, toilets, urinals, wash bowls and other apparatus shall not
     be used for any purpose other than that for which they were constructed
     and no foreign substance of any kind whatsoever shall be thrown into them.

<PAGE>
                           Exhibit B to Exhibit 10.13

                           PARKING LICENSE AGREEMENT

     Spieker Properties, L.P., a California limited partnership ("Licensor"),
hereby grants to Hyperion Solutions Corporation, a Delaware corporation
("Licensee"), the right and license to use parking spaces in Metro Center (the
"Project") as described below and subject to the following conditions:

     1.   TYPE AND NUMBER OF PARKING SPACES: Licensee shall have the right to
use up to 110 unassigned automobile parking spaces. If the area of Licensee's
Premises in the Project under the Lease between Licensor and Licensee (the
"Lease") is reduced, Licensee's allotment of parking spaces will be adjusted
proportionately based upon the Parking Density set forth in the Lease. If the
area of Licensee's Premises is increased, Licensee may, at its option, increase
the number of its allotted parking spaces proportionately. Notwithstanding the
preceding, Licensee shall have no right to use any number of parking spaces in
excess of the number of employees of Licensee actually employed at the Premises.

     2.   MONTHLY FEE: Licensee shall pay for the right and license granted
hereby the prevailing rates charged for such spaces by Licensor from time to
time ("market rate") of which is specified in the Basic Lease Information. Such
sums shall be Payable in advance on the first day of each calendar month.
Licensor shall have no obligation to accept any such payment from anyone other
than Licensee (e.g. Licensee's employees, subtenants, etc.). If Licensee fails
to make any such Payment when due, Licensor, at its option and after five (5)
days' notice to Licensee, may forthwith terminate this license and all rights of
Licensee hereunder. Any late payment of the monthly fee will result in
additional administrative and processing costs being incurred by Licensor, the
exact amount of which would be extremely difficult to determine, and it is
agreed that with respect thereto a late fee of Ten Dollars ($10.00) per space is
a reasonable estimate thereof and will be payable by Licensee with regard to any
monthly fee not paid when due. Notwithstanding anything contrary contained
herein, Licensee's employees actually employed at the Premises shall not be
charged for parking in the parking spaces licensed to Licensee hereby during the
initial six (6) year term of the Lease referenced herein.

     3.   TERM: Licensee shall be entitled to the foregoing parking rights for a
period equivalent to the term of that certain the Lease of Premises in the
Project entered into by Licensor and Licensee Licensee's rights to any and all
parking spaces shall automatically be revoked and shall terminate upon any
material default continuing for fifteen (15) days after written notice of such
default hereunder, or any expiration or termination of said Lease, as well as
upon any assignment of such Lease or sublease of such Premises, in violation of
the terms of such Lease. Licensee must exercise its rights under this Agreement
by delivering all required security deposits and the initial monthly fee for the
parking spaces described above within thirty (30) days after the Commencement
Date of the aforementioned Lease (as defined herein) unless otherwise agreed by
Licensor. Failure of Licensee to so exercise its rights will entitle Licensor
without notice to transfer to others Licensee's rights to park in any and all
parking spaces as to which Licensee has not so exercised its rights hereunder,
and Licensee will be deemed to have waived its rights hereunder with regard
thereto.

     4.   LOCATION OF PARKING SPACES: Licensor shall have the right in its sole
discretion to designate the particular location of said parking space(s) within
the Project, which designation is subject to change from time to time.

     5.   RIGHTS NON-TRANSFERABLE: The foregoing parking rights are personal to
Licensee and Licensee shall not assign, convey, or otherwise transfer said
rights in any manner whatsoever without Licensor's prior written consent. Any
attempt by Licensee to do so shall be null and void and, at Licensor's election,
shall constitute a material default hereunder. If the Premises or any Portion
thereof is assigned or sublet pursuant to the terms of the Lease, the number of
parking spaces allotted to Licensee under paragraph 1 hereof shall automatically
be adjusted accordingly and Licensor and Licensee shall immediately execute an
amendment to this Agreement setting forth (i) the number of spaces retained by
Licensee, (ii) the number of spaces allotted to Licensee's assignee or subtenant
(which number shall not exceed the amount stated in paragraph 1 above), (iii)
the then current "market rate" to be charged Licensee for the spaces allotted to
its assignee or subtenant, an (iv) the security deposit to be paid by Licensee
for its assignee's or subtenant's parking cards. Notwithstanding the foregoing,
any assignment or sublease which is permitted under Paragraph 21 of the Lease
shall not cause a reduction in the aggregate number of parking spaces and
following said assignment or sublease shall be allocated between Licensee and
the assignee or subtenant.

     6.   LICENSEE INDEMNIFICATION: Use of said parking spaces and of the
parking areas in the Project shall be at the sole risk of Licensee. Unless
caused by the negligence or wrongful acts of Licensor, its agents or employees,
Licensee hereby agrees to defend, indemnify and hold Licensor harmless against
any liability, loss, cost or expense (including reasonable attorney's fees) for
any damage to or loss or theft of any vehicle or property within any vehicle or
any other property (including property of Licensee), or injury to or death of
any person (including Licensee and Licensee's family, agents, employees,
visitors or customers), arising directly or indirectly out of or in connection
with the use by Licensee or invitees of Licensee of the parking areas or any
part thereof.

     7.   INTERRUPTION OF USE: Licensor shall not be liable to Licensee for any
interruption of Licensee's use of the right granted hereunder due to repairs,
improvements or alterations of the parking areas or the Project, or due to any
labor controversy, or resulting from any cause beyond the reasonable control of
Licensor. However, Licensee shall be entitled to an abatement of the monthly fee
with regard to any assigned parking space to the extent it is prevented from
using such space and no reasonably similar alternative space is made available
to it by Licensor.

     8.   RULES AND REGULATIONS: Licensor's parking rules and regulations are
attached hereto. Licensor may adopt such other rules and regulations relating to
the use of the parking areas as in Licensor's opinion are necessary or desirable
for the proper, orderly and safe use of the parking areas. If Licensee fails to
timely comply with the rules and regulations and modifications thereto after
receiving written notice thereof and such failure continues for fifteen (15)
days without cure, Licensor may at its option forthwith terminate this license
and all

                           PARKING LICENSE AGREEMENT

<PAGE>

rights of Licensee hereunder, and may also, whether or not such license is so
terminated, take such action as shall be required to remedy such failure, and
Licensee agrees to pay Licensor on demand the reasonable cost to Licensor of
such actions including attorneys' fees. Licensee shall at all times be required
to park in a lawful manner, and no vehicle shall at any time be parked in more
than one marked space at a time. Licensor shall be entitled to tow away any
vehicle which is improperly parked, at the vehicle owner's sole cost and
expense. In the event of such tow away, neither Licensor nor any Mortgagee of
Licensor shall have any liability therefor to Licensee or to such vehicle owner.

     9. LICENSOR'S PROPERTY RIGHTS: Licensor shall have the right to decrease
the size of any or all of the parking areas in the Project, to alter or
rearrange parking spaces and improvements in the parking areas, to take all or
any portion of the parking areas for purposes of maintaining, repairing or
restoring same, or for purposes of construction and operating structures
thereon or adjacent thereto, to have ingress and egress in connection with the
exercise of any such rights, and to do and perform such other acts with respect
to the parking areas as Licensor shall in its discretion deem appropriate.
Licensor may at any time and from time to time in its discretion designate any
portion of the parking areas in the Project for use as assigned parking,
visitor parking or employee parking. If Licensor establishes an "employee
parking" area or other assigned parking area for Licensee's employees to park
in, Licensee shall furnish Licensor, within five (5) days after written request
to do so, with a list of the vehicle license numbers of Licensee's employees
parking in the Project. Licensor may charge Licensee Ten Dollars ($10.00) per
day for each day or partial day for each vehicle parked by Licensee or any of
its employees in a parking space or area other than the space or parking area
assigned or designated for such vehicle. Licensor may tow away any such
improperly parked vehicles and may also attach violation notices or stickers
to improperly parked vehicles. In the event of such tow away, neither Licensor
nor any Mortgagee of Licensor shall have any liability therefor to Licensee or
to such vehicle owner.

     10. SECURITY DEPOSIT: If parking in a controlled lot, a monthly parking
card or decal may be issued to Licensee for each parking space to be used by
Licensee hereunder. Licensee will pay a security deposit for each parking card
at the time of issuance of the card, which is currently twenty-five ($25.00)
dollars per card, subject to change. Licensor shall have no obligation to
accept any such security deposit from anyone other than Licensee. The security
deposit shall be held by Licensor to secure Licensee's due performance of its
obligations with regard to parking hereunder and the return to Licensor of such
parking card(s) in good condition, normal wear and tear excepted, upon
termination of Licensee's rights hereunder. Licensee shall be obligated to take
reasonable steps to protect such cards from warping or mutilation. Without
limitation as to the generality of the foregoing, Licensor may apply such
security deposit to remedy any default by Licensee hereunder and further, if
such card(s) are lost or mutilated, Licensor may apply any or all of said
deposit toward Licensor's cost of such card(s). If at any time Licensor applies
any or all of such security deposit as provided herein, Licensee shall be
obligated to deposit with Licensor the amount so applied by Licensor within ten
(10) days after written request therefor is given. Upon termination of
Licensee's rights hereunder and the return to Licensor of the aforementioned
card(s) (or cards issued in substitution thereof) the security deposit or
balance thereof shall be returned to Licensee provided Licensee is not then in
default hereunder. Licensor need not hold said security deposit in a separate
account.

     11. REPLACEMENT CARDS: If for any reason (other than a malfunction for
which Licensee is not responsible hereunder) any card issued to Licensee is
requested by Licensee to be replaced, Licensee shall pay Licensor the then
current non-refundable charge for said replacement card.

     12. MISCELLANEOUS: No waiver by Licensor of any breach of this agreement
by Licensee shall constitute a waiver of any other breach. Any amount due to
Licensor that is not paid when due shall bear interest at the lesser of 12% per
annum or the maximum rate allowable under law. In the event of any legal action
taken or proceeding brought to enforce the provisions hereof, the prevailing
party shall be entitled to recover its reasonable attorney's fees and costs
incurred in connection therewith.

to incur costs not contemplated by this Lease, the exact amount of which is
extremely difficult to ascertain. Such costs include but are not limited to:
administrative, processing, accounting, and late charges which may be imposed on
Landlord by the terms of any contract, revolving credit, mortgage, or trust deed
covering the Premises. Accordingly, if any installment of Base Monthly Rent or
other sum due from Tenant shall not be received by Landlord or its designee
within five (5) business days after the rent is due, Tenant shall pay to
Landlord a late charge equal to five (5%) percent of such overdue amount, which
late charge shall be due and payable on the same date that the overdue amount
was due. The parties agree that such late charge represents a fair and
reasonable estimate of the costs Landlord will incur by reason of late payment
by Tenant, excluding interest and attorneys fees and costs. If any rent or other
sum due from Tenant remains delinquent for a period in excess of thirty (30)
days then, in addition to such late charge, Tenant shall pay to Landlord
interest on any rent that is not paid when due at the Agreed Interest Rate
specified in Section 19.J following the date such amount became due until paid.
Acceptance by Landlord of such late charge shall not constitute a waiver of
Tenant's default with respect to such overdue amount nor prevent Landlord from
exercising any of the other rights and remedies granted hereunder. In the event
that a late charge is payable hereunder, whether or not collected, for three (3)
consecutive installments of Base Monthly Rent, then the Base Monthly Rent shall
automatically become due and payable quarterly in advance, rather than monthly,
notwithstanding any provision of this Lease to the contrary.

    C. SECURITY DEPOSIT: On or before June 15, 2001, Tenant shall deposit with
Landlord the sum of Two Million Forty One Thousand Dollars ($2,041,000.00)
("Security "Deposit"). Landlord shall not be deemed a trustee of the Security
Deposit, may use the Security Deposit in business, and shall not be required to
segregate it from its general accounts. Tenant shall not be entitled to interest
on the Security Deposit. If Tenant defaults with respect to any provisions of
the Lease, including but not limited to the provisions relating to payment of
Base Monthly Rent or other charges, Landlord may, to the extent reasonably
necessary to remedy Tenant's default, use any or all of the Security Deposit
towards payment of the following: (i) Base Monthly Rent or other charges in
default; (ii) any other amount which Landlord may spend or become obligated to
spend by reason of Tenant's default including, but not limited to Tenant's
failure to restore or clean the Premises following vacation thereof. If any
portion of the Security Deposit is so used or applied, Tenant shall, within ten
(10) days after written demand from Landlord, deposit cash with Landlord in an
amount sufficient to restore the Security Deposit to its full original amount,
and shall pay to Landlord such other sums as necessary to reimburse Landlord for
any sums paid by Landlord. If Tenant shall default more than three (3) times in
any twelve (12) month period, irrespective of whether or not such default is
cured, then the Security Deposit shall, within ten (10) days after demand by
Landlord, be increased by Tenant to an amount equal to three (3) times the Base
Monthly Rent. Tenant may not assign or encumber the Security Deposit without the
consent of Landlord. Any attempt to do so shall be void and shall not be binding
on Landlord. The Security Deposit shall be returned to Tenant within thirty (30)
days after the Expiration Date and surrender of the Premises to Landlord, less
any amount deducted in accordance with this Section, together with Landlord's
written notice itemizing the amounts and purposes for such deduction.

Landlord agrees that in lieu of a cash Security Deposit, Tenant may deposit a
letter of credit ("Letter of Credit") substantially in the form attached hereto
as Exhibit "B". Landlord shall be entitled to draw against the Letter of Credit
at any time provided only that Landlord certifies

                                     Page 3
<PAGE>
to the issuer of the Letter of Credit that Tenant is in default under the Lease.
Tenant shall keep the letter of credit in effect during the entire Lease Term,
as the same may be extended, plus a period of four (4) weeks after expiration of
the Lease Term. At least thirty (30) days prior to expiration of any Letter of
Credit, the term thereof shall be renewed or extended for a period of at least
one (1) year. Tenant's failure to so renew or extend the Letter of Credit shall
be a material default of this Lease by Tenant. In the event Landlord draws
against the Letter of Credit, Tenant shall replenish the existing Letter of
Credit or cause a new Letter of Credit to be issued such that the aggregate
amount of letters of credit available to Landlord at all times during the Lease
Term is the amount of the Security Deposit originally required.

    D. CONDITIONAL SECURITY DEPOSIT REDUCTION: Provided Tenant has not been in
monetary default under the Lease during the previous 12 months of the Lease
Term, then at the commencement of the 13th month of the Lease Term and every 12
months thereafter during the initial Lease Term, , Tenant shall be allowed to
reduce the amount of the cash Security Deposit or Letter of Credit by
$408,000.00.

5. CONSTRUCTION: This section has been intentionally omitted as Landlord is
performing no construction work for Tenant pursuant to the terms of this Lease.

6.  ACCEPTANCE OF POSSESSION AND COVENANTS TO SURRENDER:

    A. DELIVERY AND ACCEPTANCE: On the Commencement Date, Landlord shall deliver
and Tenant shall accept possession of the Premises and enter into occupancy of
the Premises on the Commencement Date. Tenant acknowledges that it has had an
opportunity to conduct, and has conducted, such inspections of the Premises as
it deems necessary to evaluate its condition. Except as otherwise specifically
provided herein, Tenant agrees to accept possession of the Premises in its then
existing condition, subject to all Restrictions and without representation or
warranty by Landlord.

On the Commencement Date, Landlord agrees to deliver the Building to Tenant with
all HVAC, mechanical systems, and the roof in good operating condition and
repair.

    B. CONDITION UPON SURRENDER: Tenant further agrees on the Expiration Date or
on the sooner termination of this Lease, to surrender the Premises to Landlord
in good condition and repair, normal wear and tear, casualty, and condemnation
excepted. In this regard, "normal wear and tear" shall be construed to mean wear
and tear caused to the Premises by the natural aging process which occurs in
spite of prudent application of the best commercially reasonable standards for
maintenance, repair replacement, and janitorial practices, and does not include
items of neglected or deferred maintenance. In any event, Tenant shall cause the
following to be done prior to the Expiration Date or sooner termination of this
Lease: (i) all interior walls shall be cleaned, patched, and otherwise made
paint-ready, (ii) all tiled floors shall be cleaned and waxed, (iii) all carpets
shall be cleaned and shampooed, (iv) all broken, marred, stained or
nonconforming acoustical ceiling tiles shall be replaced, (v) all cabling placed
above the ceiling by Tenant or Tenant's contractors shall be removed, (vi) all
windows shall be washed; (vii) the HVAC system shall be serviced by a reputable
and licensed service firm and left in "good operating condition and repair" as
so certified by such firm, (viii) the plumbing and electrical systems and
lighting shall be placed in good order and repair (including replacement of any
burned out, discolored or broken light bulbs, ballasts, or lenses. On or before
the Expiration Date or sooner termination of this Lease, Tenant shall remove all
its personal property and trade fixtures from the Premises. All property and
fixtures not so removed shall be deemed as abandoned by Tenant. Except as
otherwise agreed between the parties, Tenant shall ascertain from Landlord
within ninety (90) days before the Expiration Date whether Landlord desires to
have any Permitted Alterations made by Tenant (as defined in Section 7) removed
and the Premises or any parts thereof restored to a standard open office plan
with materials and finishes consistent with the other open office areas with the
Premises, or to cause Tenant to surrender all Alterations in

                                     Page 4
<PAGE>
place to Landlord. If Landlord shall so desire, Tenant shall, at Tenant's sole
cost and expense, remove such Alterations as Landlord requires and shall repair
and restore said Premises or such parts thereof before the Expiration Date. Such
repair and restoration shall include causing the Premises to be brought into
compliance with all applicable building codes and laws in effect at the time of
the removal to the extent such compliance is necessitated by the repair and
restoration work.

    C. FAILURE TO SURRENDER: If the Premises are not surrendered at the
Expiration Date or sooner termination of this Lease in the condition required by
this Section 6, Tenant shall be deemed in a holdover tenancy pursuant to this
Section 6.C and Tenant shall indemnify, defend, and hold Landlord harmless
against loss or liability resulting from delay by Tenant in so surrendering the
Premises including, without limitation, any claims made by any succeeding tenant
founded on such delay and costs incurred by Landlord in returning the Premises
to the required condition, plus interest at the Agreed Interest Rate. If Tenant
remains in possession of the Premises after the Expiration Date or sooner
termination of this Lease without Landlord's consent, Tenant's continued
possession shall be on the basis of a tenancy at sufferance and Tenant shall pay
as rent during the holdover period an amount equal to one hundred fifty percent
(150%) of the Base Monthly Rent due in the month preceding the termination or
Expiration Date, plus all other amounts payable by Tenant under this Lease. Any
holding over shall otherwise be on the terms and conditions herein specified,
except those provisions relating to the Lease Term and any options to extend or
renew, which provisions shall be of no further force and effect following the
expiration of the applicable exercise period. This provision shall survive the
termination or expiration of the Lease.

7.  ALTERATIONS AND ADDITIONS:

    A. TENANT'S ALTERATIONS: Tenant shall not make, or suffer to be made, any
alteration or addition to the Premises ("Alterations"), or any part thereof,
without obtaining Landlord's prior written consent, which shall not be
unreasonably withheld or delayed, and delivering to Landlord the proposed
architectural and structural plans for all such Alterations at least fifteen
(15) days prior to the start of construction. If such Alterations affect the
structure of the Building, Tenant additionally agrees to reimburse Landlord its
reasonable out-of-pocket costs incurred in reviewing Tenant's plans. After
obtaining Landlord's consent, which consent shall state whether or not Landlord
will require Tenant to remove such Alteration at the expiration or earlier
termination of this Lease, Tenant shall not proceed to make such Alterations
until Tenant has obtained all required governmental approvals and permits, and
provides Landlord reasonable security, in form reasonably approved by Landlord,
to protect Landlord against mechanics' lien claims. Tenant agrees to provide
Landlord (i) written notice of the anticipated and actual start-date of the
work, (ii) a complete set of half-size (15" X 21") vellum as-built drawings, and
(iii) a certificate of occupancy for the work upon completion of the
Alterations. All Alterations shall be constructed in compliance with all
applicable building codes and laws including, without limitation, the Americans
with Disabilities Act of 1990 as amended from time to time. Upon the Expiration
Date, all Alterations, except movable furniture and trade fixtures, shall become
a part of the realty and belong to Landlord but shall nevertheless be subject to
removal by Tenant as provided in Section 6 above. Alterations which are not
deemed as trade fixtures include heating, lighting, electrical systems, air
conditioning, walls, carpeting, or any other installation which has become an
integral part of the Premises. All Alterations shall be maintained, replaced or
repaired by Tenant at its sole cost and expense.

Notwithstanding the foregoing, Tenant shall be entitled, without obtaining
Landlord's consent, to make Alterations which do not affect the structure of the
Building or which do not cost more than Fifty Thousand Dollars ($50,000.00) per
Alteration nor an aggregate of One Hundred Thousand Dollars ($100,000.00) in any
twelve (12) month period ("Permitted Alterations"); provided, however, that: (i)
Tenant shall still be required to comply with all other provisions of this
paragraph; and (ii) such Permitted

                                     Page 5
<PAGE>
Alterations are subject to removal by Tenant at Landlord's election pursuant to
Section 6.B. above at the expiration or earlier termination of the Lease.

    B. FREE FROM LIENS: Tenant shall keep the Premises free from all liens
arising out of work performed, materials furnished, or obligations incurred by
Tenant or claimed to have been performed for Tenant. In the event Tenant fails
to discharge any such lien within ten (10) days after receiving notice of the
filing, Landlord shall immediately be entitled to discharge the lien at Tenant's
expense and all resulting costs incurred by Landlord, including attorney's fees
shall be due from Tenant as additional rent.

    C. COMPLIANCE WITH GOVERNMENTAL REGULATIONS: The term Laws or Governmental
Regulations shall include all federal, state, county, city or governmental
agency laws, statutes, ordinances, standards, rules, requirements, or orders now
in force or hereafter enacted, promulgated, or issued. The term also includes
government measures regulating or enforcing public access, traffic mitigation,
occupational, health, or safety standards for employers, employees, landlords,
or tenants. Tenant, at Tenant's sole expense will comply with all such
Governmental Regulations and shall make all repairs, replacements, alterations,
or improvements necessary to comply with all Governmental Regulations. The
judgment of any court of competent jurisdiction or the admission of Tenant in
any action or proceeding against Tenant (whether Landlord be a party thereto or
not) that Tenant has violated any such law, regulation or other requirement in
its use of the Premises shall be conclusive of that fact as between Landlord and
Tenant. All costs associated with compliance with this Section 7.C. shall be
borne by Tenant if the requirement for compliance is triggered by: (i) Tenant's
specific use (other than general office or light manufacturing) or change of use
of the Premises; (ii) Tenant's application for any permit or governmental
approval; or (iii) Tenant's construction, installation, or removal of any
Alterations or trade fixtures. If a capital improvement or replacement to the
Premises is required for any other reason, then within ten (10) business days
after Tenant delivers evidence reasonably satisfactory to Landlord
substantiating that the capital improvement or replacement has been performed
and the cost is due, Landlord shall reimburse Tenant for the cost of the
improvement or replacement less that portion of the cost equal to the product of
such total cost multiplied by a fraction, the numerator of which is the number
of years remaining in the Lease Term, the denominator of which is the useful
life (in years) of the capital improvement, as reasonably determined by Landlord
in accordance with generally accepted accounting principles. If the capital
improvement is made during the initial Lease Term, Tenant's share shall
initially be based on the initial Lease Term and if Tenant thereafter exercises
its renewal option, then upon the commencement of the Option term, an adjustment
shall be made so that during the Option Term Tenant shall pay its share
determined by multiplying the cost of the capital improvement by a fraction, the
numerator of which is the sum of the Lease Term remaining at the time the
capital expenditure was made and the Option Term and the denominator of which is
the useful life of the capital improvement.

Notwithstanding the foregoing, Tenant shall not be responsible for the cost of
compliance with Laws and Governmental Regulations related to alterations to the
Premises made by or on behalf of the previous tenant, excluding any alterations
made for Tenant during its sublease occupancy of the Premises.

8.  MAINTENANCE OF PREMISES:

    A. LANDLORD'S OBLIGATIONS: Landlord, at its sole cost and expense and
without any right of reimbursement from Tenant, shall maintain in good
condition, order, and repair, and replace as and when necessary, the foundation,
exterior load bearing walls and roof structure of the Building.

    B. TENANT'S OBLIGATIONS: Tenant shall clean, maintain, repair and replace
when necessary the Premises and every part thereof through regular inspections
and servicing, including but not limited to: (i) all plumbing and sewage
facilities, (ii) all heating ventilating and

                                     Page 6
<PAGE>
air conditioning facilities and equipment, (iii) all fixtures, interior walls
floors, carpets and ceilings, (iv) all windows, door entrances, plate glass and
glazing systems including caulking, and skylights, (v) all electrical facilities
and equipment, (vi) all automatic fire extinguisher equipment, (vii) the parking
lot and all underground utility facilities servicing the Premises, (viii) the
roof membrane system, and (ix) all waterscape, landscaping and shrubbery. All
wall surfaces and floor tile are to be maintained in an as good a condition as
when Tenant took possession free of holes, gouges, or defacements. With respect
to items (ii) and (viii) above, Tenant shall provide Landlord a copy of a
service contract between Tenant and a licensed service contractor providing for
periodic maintenance of all such systems or equipment in conformance with the
manufacturer's recommendations. Tenant shall provide Landlord a copy of such
preventive maintenance contracts and paid invoices for the recommended work if
requested by Landlord. If as a part of Tenant's fulfilment of its maintenance
obligations under this Section 8.B. during the last three (3) years of the Lease
Term, a roof replacement to the Premises is paid for by Tenant, Landlord shall
reimburse Tenant for the cost of the replacement less the sum of (i) Fifty
Thousand Dollars ($50,000.00) plus (ii) that portion of the cost over $50,000.00
equal to the product of such cost multiplied by a fraction, the numerator of
which is the number of years remaining in the Lease Term, the denominator of
which is the useful life (in years) of the roof replacement. Further, if as a
part of Tenant's fulfilment of its maintenance obligations under this Section
8.B. an HVAC unit replacement to the Premises is paid for by Tenant, Landlord
shall reimburse Tenant for the cost of the replacement less the sum of (i)
Fifteen Thousand Dollars ($15,000.00) plus (ii) that portion of the cost over
$15,000.00 equal to the product of such cost multiplied by a fraction, the
numerator of which is the number of years remaining in the Lease Term, the
denominator of which is the useful life (in years) of the new HVAC unit. If the
roof replacement or HVAC unit replacement is made during the initial Lease Term,
Tenant's share shall initially be based on the initial Lease Term and if Tenant
thereafter exercises its renewal option, then upon the commencement of the
Option term, an adjustment shall be made so that during the Option Term Tenant
shall reimburse Landlord an amount determined by multiplying the cost of the
replacement by a fraction, the numerator of which is the sum of the Lease Term
remaining at the time the replacement was made and the Option Term and the
denominator of which is the useful life of the new roof or HVAC unit.

    C. LANDLORD AND TENANT'S OBLIGATIONS REGARDING REIMBURSABLE OPERATING COSTS:
In addition to the direct payment by Tenant of expenses as provided in Sections
8.B, 9, 10 and 11 of this Lease, Tenant agrees to reimburse Landlord for
Tenant's Allocable Share (as defined in Section 8.E below) of Reimbursable
Operating Costs (as defined in Section 8.D below) resulting from Landlord
payment of expenses related to the Building or Project which are not otherwise
paid by Tenant directly. Tenant agrees to pay its Allocable Share of the
Reimbursable Operating Costs as additional rental within ten (10) days of
written invoice from Landlord. In no event shall Tenant be responsible to pay
any expense associated with Building 1 or Building 2.

    D. REIMBURSABLE OPERATING COSTS: For purposes of calculating Tenant's
Allocable Share of Building and Project Costs, the term "Reimbursable Operating
Costs" is defined as all costs and expenses of the nature hereinafter described
which are incurred by Landlord in connection with ownership and operation of the
Building or the Project in which the Premises are located, together with such
additional facilities as may be determined by Landlord to be reasonably
desirable or necessary to the ownership and operation of the Building and/or
Project. All costs and expenses shall be determined in accordance with generally
accepted accounting principles which shall be consistently applied (with
accruals appropriate to Landlord's business), including but not limited to the
following: (i) common area utilities, including water, power, telephone,
heating, lighting, air conditioning, ventilating, and Building utilities to the
extent not separately metered; (ii) common area maintenance and service
agreements for the Building and/or Project and the equipment therein, including

                                     Page 7
<PAGE>
without limitation, common area janitorial services, alarm and security
services, exterior window cleaning, and maintenance of the sidewalks,
landscaping, waterscape, roof membrane, parking areas, driveways, service areas,
mechanical rooms, and the building exterior; (iii) insurance premiums and costs,
including without limitation, the reasonable premiums and cost of fire, casualty
and liability coverage and rental abatement and, if elected by Landlord,
earthquake insurance applicable to the Building or Project; (iv) repairs,
replacements and general maintenance (excluding repairs and general maintenance
paid by proceeds of insurance or by Tenant or other third parties, and repairs
or alterations attributable solely to tenants of the Building or Project other
than Tenant); and (v) all real estate taxes and assessment installments or other
impositions or charges which may be levied on the Building or Project, upon the
occupancy of the Building or Project and including any substitute or additional
charges which may be imposed during, or applicable to the Lease Term including
real estate tax increases due to a sale, transfer or other change of ownership
of the Building or Project, as such taxes are levied or appear on the City and
County tax bills and assessment rolls. Landlord shall have no obligation to
provide guard services or other security measures for the benefit of the
Project. Tenant assumes all responsibility for the protection of Tenant and
Tenant's Agents from acts of third parties; provided, however, that nothing
contained herein shall prevent Landlord, at its sole option, from providing
security measures for the Project. This is a "Net" Lease, meaning that Base
Monthly Rent is paid to Landlord absolutely net of all costs and expenses. The
provision for payment of Reimbursable Operating Costs by means of periodic
payment of Tenant's Allocable Share of Building and/or Project Costs is intended
to pass on to Tenant and reimburse Landlord for all costs of operating and
managing the Building and/or Project.

Notwithstanding anything to the contrary contained in this Lease, the following
shall not be included within Reimbursable Operating Costs: (i) leasing
commissions, attorneys' fees, costs, disbursements, and other expenses incurred
in connection with negotiations or disputes with tenants or in connection with
leasing, renovating, or improving space for tenants or other occupants or
prospective tenants or other occupants of the Building or the Project; (ii) the
cost of any service sold to any tenant (including Tenant) or other occupant for
which Landlord is entitled to be reimbursed as an additional charge or rental
over and above the basic rent and escalations payable under the lease with that
tenant; (iii) any depreciation on the Building or the Project; (iv) expenses in
connection with services or other benefits of a type that are not provided to
Tenant but which are provided another tenant or occupant of the Building or
Project; (v) costs incurred due to Landlord's violation of any terms or
conditions of this Lease or any other lease relating to the Building or Project;
(vi) overhead profit increments paid to Landlord's subsidiaries or affiliates
for services on or to the Building or Project or for supplies or other materials
to the extent that the cost of the services, supplies, or materials exceeds the
cost that would have been paid had the services, supplies, or materials been
provided by unaffiliated parties on a competitive basis; (vii) all interest,
loan fees, and other carrying costs related to any mortgage or deed of trust,
and all rental and other payable due under any ground or underlying lease;
(viii) any compensation paid to clerks, attendants, or other persons in
commercial concessions operated by Landlord; (ix) advertising and promotional
expenditures; (x) any costs, fines, or penalties incurred due to violations by
Landlord of any governmental rule or authority, this Lease or any other lease in
the Project, or due to Landlord's active negligence or willful misconduct; (xi)
costs for sculpture, paintings, or other objects of art (nor insurance thereon
or extraordinary security in connection therewith); (xii) wages, salaries, or
other compensation paid to any executive employees above the grade of building
manager; (xiii) the cost of correcting any building code or other violations
which were violations prior to the Commencement Date; (xiv) reserves for any
Reimbursable Operating Costs; (xv) repairs and maintenance to buildings of the
Project in which Tenant is not an occupant, and (xvi) any property management or
similar fee.

                                     Page 8
<PAGE>
    E. TENANT'S ALLOCABLE SHARE: For purposes of prorating Reimbursable
Operating Costs which Tenant shall pay, Tenant's Allocable Share of Reimbursable
Operating Costs shall be computed by multiplying the Reimbursable Operating
Costs by a fraction, the numerator of which is the rentable square footage of
the Premises and the denominator of which is either the total rentable square
footage of the Building if the service or cost is allocable only to the
Building, or the total square footage of the Project if the service or cost is
allocable to the entire Project. Tenant's obligation to share in Reimbursable
Operating Costs shall be adjusted to reflect the Lease Commencement and
Expiration dates and is subject to recalculation in the event of expansion of
the Building or Project.

Tenant shall have the right to audit Landlord's business records relating to the
calculation of Tenant's Allocable Share subject to the following: (i) the audit
shall be at the sole cost of the Tenant (unless such audit reveals a discrepancy
in favor of Tenant of greater than 5%, in which case Landlord shall pay the
cost); (ii) the audit shall be conducted at Landlord's office or such other
reasonable location as Landlord may designate, during normal business hours;
(iii) the audit shall be conducted after reasonable notice to Landlord; and (iv)
Tenant shall maintain the results of such audit confidential.

    F. WAIVER OF LIABILITY: Failure by Landlord to perform any defined services,
or any cessation thereof, when such failure is caused by accident, breakage,
repairs, strikes, lockout or other labor disturbances or labor disputes of any
character or by any other cause, similar or dissimilar, unless due to the active
negligence or willful misconduct of Landlord, shall not render Landlord liable
to Tenant in any respect, including damages to either person or property, nor be
construed as an eviction of Tenant, nor cause an abatement of rent, nor relieve
Tenant from fulfillment of any covenant or agreement hereof. Should any
equipment or machinery utilized in supplying the services listed herein break
down or for any cause cease to function properly, upon receipt of written notice
from Tenant of any deficiency or failure of any services, Landlord shall use
reasonable diligence to repair the same promptly, but Tenant shall have no right
to terminate this Lease and shall have no claim for rebate of rent or damages on
account of any interruptions in service occasioned thereby or resulting
therefrom. If Landlord fails to use reasonable diligence to make repairs for
which it is responsible under this Section 8 and imminent injury to persons or
damage to property may result therefrom, Tenant may make such repairs and
Landlord shall pay the reasonable cost thereof within thirty (30) days after
written demand. Tenant waives the provisions of California Civil Code Sections
1941 and 1942 concerning the Landlord's obligation of tenantability and Tenant's
right to make repairs and deduct the cost of such repairs from the rent.
Landlord shall not be liable for a loss of or injury to person or property,
however occurring, through or in connection with or incidental to furnishing, or
its failure to furnish, any of the foregoing unless due to Landlord's active
negligence or willful misconduct.

9.  HAZARD INSURANCE:

    A. TENANT'S USE: Tenant shall not use or permit the Premises, or any part
thereof, to be used for any purpose other than that for which the Premises are
hereby leased; and no use of the Premises shall be made or permitted, nor acts
done, which will cause an increase in premiums or a cancellation of any
insurance policy covering the Premises or any part thereof, nor shall Tenant
sell or permit to be sold, kept, or used in or about the Premises, any article
prohibited by the standard form of fire insurance policies. Tenant shall, at its
sole cost, comply with all requirements of any insurance company or organization
necessary for the maintenance of reasonable fire and public liability insurance
covering the Premises and appurtenances.

    B. LANDLORD'S INSURANCE: Landlord agrees to purchase and keep in force All
Risk and fire insurance in an amount equal to the replacement cost of the
Building (not including any Tenant Improvements or Alterations paid for by
Tenant from sources other than the Work Allowance) as determined by Landlord's

                                     Page 9
<PAGE>
insurance company's appraisers. At Landlord's election, such fire and property
damage insurance may be endorsed to cover loss caused by such additional perils
against which Landlord may elect to insure, including earthquake and/or flood,
and shall contain reasonable deductibles. Additionally Landlord may maintain a
policy of (i) commercial general liability insurance insuring Landlord (and such
others designated by Landlord) against liability for personal injury, bodily
injury, death and damage to property occurring or resulting from an occurrence
in, on or about the Premises or Project in an amount as Landlord determines is
reasonably necessary for its protection, and (ii) rental lost insurance covering
a twelve (12) month period. Tenant agrees to pay Landlord as additional rent, on
demand, the full cost (subject to Tenant's Allocable Share as defined in Section
8.E.) of said insurance as evidenced by insurance billings to Landlord, and in
the event of damage covered by said insurance, the amount of any deductible
under such policy. Payment shall be due to Landlord within ten (10) days after
written invoice to Tenant. It is understood and agreed that Tenant's obligation
under this Section will be prorated to reflect the Lease Commencement and
Expiration Dates.

    C. TENANT'S INSURANCE: Tenant agrees, at its sole cost, to insure its
personal property, Tenant Improvements (for which it has paid from sources other
than the Work Allowance), and Alterations against damage for their full
replacement value (without depreciation). Said insurance shall provide All Risk
and fire coverage equal to the replacement cost of said property. The property
casualty insurance provided by Tenant as required by this paragraph shall be
carried in favor of Landlord and Tenant as their respective interests may appear
and shall provide that any loss to Tenant Improvements shall be adjusted with
and be payable to both Landlord and Tenant. Tenant shall deliver a copy of the
policy and renewal certificate to Landlord. Tenant agrees, at its sole cost, and
to obtain worker's compensation and Commercial General Liability insurance for
occurrences within the Premises with a combined single limit of not less than
Five Million Dollars ($5,000,000.00). Tenant's liability insurance shall be
primary insurance containing a cross-liability endorsement, and shall provide
coverage on an "occurrence" rather than on a "claims made" basis. All such
insurance shall provide for severability of interests; shall provide that an act
or omission of one of the named (additional) insureds shall not reduce or avoid
coverage to the other named (additional insureds). Tenant shall name Landlord
and Landlord's lender as an additional insured and shall deliver a copy of the
policies and renewal certificates to Landlord. All insurance policies required
under this section shall provide for thirty (30) days' prior written notice to
Landlord of any cancellation, termination, or reduction in coverage.
Notwithstanding the above, Landlord retains the right to have Tenant provide
other forms of insurance which may be reasonably required to cover future risks.

    D. WAIVER: Landlord and Tenant hereby waive all tort, contract or other
rights each may have against the other on account of any loss or damage
sustained by Landlord or Tenant, as the case may be, or to the Premises or its
contents, which may arise from any risk covered by their respective insurance
policies (or which would have been covered had such insurance policies been
maintained in accordance with this Lease) as set forth above. The Parties shall
each obtain from their respective insurance companies a waiver of any right of
subrogation which said insurance company may have against Landlord or Tenant, as
the case may be.

10. TAXES: Tenant shall be liable for and shall pay as additional rental, prior
to delinquency, the following: (i) all taxes and assessments levied against
Tenant's personal property and trade or business fixtures; (ii) all real estate
taxes and assessment installments or other impositions or charges which may be
levied on the Premises or upon the occupancy of the Premises, including any
substitute or additional charges which may be imposed applicable to the Lease
Term; and (iii) real estate tax increases due to an increase in assessed value
resulting from a sale, transfer or other change of ownership of the Premises as
it appears on the City and County tax bills during the Lease Term. All real
estate taxes shall be prorated to reflect the Lease Commencement and Expiration
Dates. If, at any time during the Lease Term a tax, excise on

                                    Page 10
<PAGE>
rents, business license tax or any other tax, however described, is levied or
assessed against Landlord as a substitute or addition, in whole or in part, for
taxes assessed or imposed on land or Buildings, Tenant shall pay and discharge
its pro rata share of such tax or excise on rents or other tax before it becomes
delinquent; except that this provision is not intended to cover net income
taxes, inheritance, gift or estate tax imposed upon Landlord. In the event that
a tax is placed, levied, or assessed against Landlord and the taxing authority
takes the position that Tenant cannot pay and discharge its pro rata share of
such tax on behalf of Landlord, then at Landlord's sole election, Landlord may
increase the Base Monthly Rent by the exact amount of such tax and Tenant shall
pay such increase. If by virtue of any application or proceeding brought by
Landlord, there results a reduction in the assessed value of the Premises during
the Lease Term, Tenant agrees to pay Landlord a fee consistent with the fees
charged by a third party appeal firm for such services.

11. UTILITIES: Tenant shall pay directly to the providing utility all water,
gas, electric, telephone, and other utilities supplied to the Premises. Landlord
shall not be liable for loss of or injury to person or property, however
occurring, through or in connection with or incidental to furnishing or the
utility company's failure to furnish utilities to the Premises, and in such
event Tenant shall not be entitled to abatement or reduction of any portion of
Base Monthly Rent or any other amount payable under this Lease.

12. TOXIC WASTE AND ENVIRONMENTAL DAMAGE:

    A. USE OF HAZARDOUS MATERIAL: Without the prior written consent of Landlord,
Tenant or Tenant's agents, employees, contractors, subtenants or invitees
("Tenant's Agents") shall not cause or permit any Hazardous Material, as defined
below, to be generated, brought onto, used, stored, created, released or
disposed of in or about the Premises, except that Tenant may use and store small
quantities of common household cleaners and office supplies on the Premises
provided such use and storage is in strict compliance with all Environmental
Laws, as defined below. As used herein, the term "Hazardous Material" shall mean
any substance, material or waste (whether liquid, solid or gaseous), which is a
pollutant or contaminant, or which is hazardous, toxic, ignitable, reactive,
corrosive, dangerous, harmful or injurious, or which presents a risk to public
health or the environment, or which is or may become regulated by or under the
authority of any Environmental Laws, as defined below, including, without
limitation, asbestos or asbestos containing materials, petroleum products,
pesticides, polychlorinated biphenyls, flammable explosives, radioactive
materials and urea formaldehyde. As used herein, the term "Environmental Laws"
shall mean any present or future federal, state or local law, whether common
law, statute, rule, regulation or ordinance, judgment, order, or other
governmental restriction, guideline, listing or requirement, relating to the
environment or any Hazardous Material, including without limitation, the
Comprehensive Environmental Response, Compensation, and Liability Act of 1980,
42 U.S.C. Section 9601 et seq., the Resource Conservation and Recovery Act of
1976, 42 U.S.C. Section 6901 et seq., and applicable provisions of the
California Health and Safety Code and the California Water Code, all as
heretofore or hereafter may be amended from time to time. In order to obtain
consent, Tenant shall deliver to Landlord its written proposal describing the
Hazardous Material to be brought onto the Premises, measures to be taken for
storage and disposal thereof, and safety measures to be employed to prevent
pollution or contamination of the air, soil, surface and ground water.
Landlord's approval may be withheld in its reasonable judgment. In the event
Landlord consents to Tenant's use of Hazardous Materials on the Premises or such
consent is not required, Tenant represents and warrants that it shall comply
with all Governmental Regulations applicable to Hazardous Material including
doing the following: (i) adhere to all reporting and inspection requirements
imposed by Federal, State, County or Municipal laws, ordinances or regulations
and provide Landlord a copy of any such reports or agency inspections; (ii)
obtain and provide Landlord copies of all necessary permits required for the use
and handling of Hazardous Material on the

                                    Page 11
<PAGE>
Premises; (iii) enforce Hazardous Material handling and disposal practices
consistent with industry standards; (iv) surrender the Premises free from any
Hazardous Materials arising from Tenant's generating, bringing, using, storing,
creating, releasing, or disposing of Hazardous Material; and (v) properly close
the facility with regard to Hazardous Material including the removal or
decontamination of any process piping, mechanical ducting, storage tanks,
containers, or trenches which have come into contact with Hazardous Material and
obtaining a closure certificate from the local administering agency prior to the
Expiration Date.

    B. TENANT'S INDEMNITY REGARDING HAZARDOUS MATERIAL: Tenant shall, at its
sole cost and expense and with counsel reasonably acceptable to Landlord,
indemnify, defend and hold harmless Landlord and Landlord's trustees,
shareholders, directors, officers, employees, partners, affiliates, agents,
successors and assigns from, and against any and all claims, liabilities,
obligations, penalties, fines, actions, costs or expenses incurred or suffered
arising from generating, bringing, using, storing, creating, releasing or
disposing of Hazardous Material by Tenant or Tenant's Agents in or about the
Premises, or the violation of any Governmental Regulation or Environmental Laws
by Tenant or Tenant's Agents. This indemnification applies whether or not the
concentrations of any such Hazardous Material exceed applicable maximum
contaminant or action levels or any governmental agency has issued a cleanup
order. Tenant's indemnification, defense, and hold harmless obligations include,
without limitation, the following: (i) claims, liabilities, costs or expenses
resulting from or based upon administrative, judicial (civil or criminal) or
other action, legal or equitable, brought by any private or public person under
present or future laws, including Environmental Laws; (ii) claims, liabilities,
costs or expenses pertaining to the identification, monitoring, cleanup,
containment, or removal of Hazardous Material from soils, riverbeds or aquifers
including the provision of an alternative public drinking water source; (iii)
losses attributable to diminution in the value of the Premises or the Building
(iv) loss or restriction of use of rentable space in the Building; (v) adverse
effect on the marketing of any space in the Building; and (vi) all other
liabilities, obligations, penalties, fines, claims, actions (including remedial
or enforcement actions of any kind and administrative or judicial proceedings,
orders or judgments), damages (including consequential and punitive damages),
and costs (including attorney, consultant, and expert fees and expenses)
resulting from the release or violation. This Section 12.B shall survive the
expiration or termination o this Lease.

    C. NOTICE OF RELEASE OR VIOLATION: If, during the Lease Term (including any
extensions), Tenant becomes aware of (i) any actual or threatened release of a
Hazardous Material on, under or about the Premises or (ii) any inquiry,
investigation, proceeding, claim, notice or order by any private or public
person or entity regarding the presence of Hazardous Material on, under or about
the Premises, including alleged violations of Environmental Laws by Tenant or
Tenant's Agents., Tenant shall give Landlord written notice of the release or
investigation within five (5) days after learning of it and shall simultaneously
and thereafter furnish Landlord with copies of any claims, notices of violation,
reports, or other writings received by Tenant concerning the release or
investigation. In the event of an actual release of Hazardous Materials, Tenant
shall also give Landlord immediate verbal notice of such release.

        In the event of any release on or into the Premises or into the soil or
ground water under the Premises, the Building or the Project of any Hazardous
Materials used, treated, stored or disposed of by Tenant or Tenant's Agents,
Tenant agrees to comply, at its sole cost, with all laws, regulations,
ordinances and orders of any federal, state or local agency relating to the
monitoring or remediation of such Hazardous Materials. In the event of any such
release of Hazardous Materials Tenant shall immediately give verbal and
follow-up written notice of the release to Landlord, and Tenant agrees to meet
and confer with Landlord and its Lender to attempt to eliminate and mitigate any
financial exposure to such Lender and resultant exposure to Landlord under
California Code of Civil

                                    Page 12
<PAGE>
Procedure Section 736(b) as a result of such release, and promptly to take
reasonable monitoring, cleanup and remedial steps given, inter alia, the
historical uses to which the Property has and continues to be used, the risks to
public health posed by the release, the then available technology and the costs
of remediation, cleanup and monitoring, consistent with acceptable customary
practices for the type and severity of such contamination and all applicable
laws. Nothing in the preceding sentence shall eliminate, modify or reduce the
obligation of Tenant under 12.B of this Lease to indemnify, defend and hold
Landlord harmless from any claims liabilities, costs or expenses incurred or
suffered by Landlord. Tenant shall provide Landlord prompt written notice of
Tenant's monitoring, cleanup and remedial steps.

    In the absence of an order of any federal, state or local governmental or
quasi-governmental agency relating to the cleanup, remediation or other response
action required by applicable law, any dispute arising between Landlord and
Tenant concerning Tenant's obligation to Landlord under this Section 12.C
concerning the level, method, and manner of cleanup, remediation or response
action required in connection with such a release of Hazardous Materials shall
be resolved by mediation and/or arbitration pursuant to this Lease.

    D. REMEDIATION OBLIGATIONS: In the event of any release on, under or about
the Premises of any Hazardous Material generated, brought onto, used, stored,
created or disposed of by Tenant or Tenant's Agents, Tenant shall, at its sole
cost, promptly take all necessary and appropriate actions, in compliance with
applicable Environmental Laws, to remove or remediate such Hazardous Material,
whether or not any governmental agency has issued a cleanup order, so as to
return the Premises to the condition that existed before the introduction of
such Hazardous Material. Tenant shall obtain Landlord's written consent prior to
implementing any proposed removal or remedial action, provided, however, that
Tenant shall be entitled to respond immediately to an emergency without first
obtaining Landlord's written consent. Nothing in the preceding sentence shall in
any way eliminate, modify or reduce the obligation of Tenant under 12.B of this
Lease to indemnify, defend and hold Landlord harmless from any claims,
liabilities, costs or expenses incurred or suffered by Landlord.

    E. ENVIRONMENTAL MONITORING: Landlord and its agents shall have the right to
inspect, investigate, sample and monitor the Premises, including any air, soil,
water, ground water, or to conduct any other sampling or testing, digging,
drilling or analysis, to determine whether Tenant is complying with the terms of
this Section 12. Such work shall be at Landlord's expense provided, however,
that if Landlord discovers that Tenant is not in compliance with the terms of
this Section 12, any costs incurred by Landlord in determining Tenant's non-
compliance, including attorneys', consultants' and experts' fees, shall be due
and payable by Tenant to Landlord within five (5) days following Landlord's
written demand therefor.

13. TENANT'S DEFAULT: The occurrence of any of the following shall constitute a
material default and breach of this Lease by Tenant: (i) Tenant's failure to pay
the Base Monthly Rent including additional rent or any other payment due under
this Lease by the date such amount is due, and such failure continues after five
(5) days' written notice from Landlord, (ii) the abandonment (but not the
vacating) of the Premises by Tenant; (iii) Tenant's failure to observe and
perform any other required provision of this Lease, where such failure continues
for thirty (30) days after written notice from Landlord provided, however, that
if the nature of the default is such that it cannot reasonably be cured within
the 30-day period, Tenant shall not be deemed in default if it commences within
such period to cure, and thereafter diligently prosecutes the same to
completion; (iv) Tenant's making of any general assignment for the benefit of
creditors; (v) the filing by or against Tenant of a petition to have Tenant
adjudged a bankrupt or of a petition for reorganization or arrangement under any
law relating to bankruptcy (unless, in the case of a petition filed against
Tenant, the same is

                                    Page 13
<PAGE>
dismissed after the filing); (vi) the appointment of a trustee or receiver to
take possession of substantially all of Tenant's assets located at the Premises
or of Tenant's interest in this Lease, where possession is not restored to
Tenant within thirty (30) days; (vii) the attachment, execution or other
judicial seizure of substantially all of Tenant's assets located at the Premises
or of Tenant's interest in this Lease, where such seizure is not discharged
within thirty (30) days; or (viii) the occurrence of any other event described
as a default elsewhere in this Lease or any amendment thereto regardless of
whether such event is defined as a material default and breach of this Lease in
this Paragraph 13.

    A. REMEDIES: In the event of any such default by Tenant, then in addition to
other remedies available to Landlord at law or in equity, Landlord shall have
the immediate option to terminate this Lease and all rights of Tenant hereunder
by giving written notice of such intention to terminate. In the event Landlord
elects to so terminate this Lease, Landlord may recover from Tenant all the
following: (i) the worth at time of award of any unpaid rent which had been
earned at the time of such termination; (ii) the worth at 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 for the same
period that Tenant proves could have been reasonably avoided; (iii) the worth at
time of award of the amount by which the unpaid rent for the balance of the
Lease Term after the time of award exceeds the amount of such rental loss that
Tenant proves could be reasonably avoided; (iv) any other amount necessary to
compensate Landlord for all 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 the following: (x)
expenses for repairing, altering or remodeling the Premises for purposes of
reletting, (y) broker's fees, advertising costs or other expenses of reletting
the Premises, and (z) costs of carrying the Premises such as taxes, insurance
premiums, utilities and security precautions; and (v) at Landlord's election,
such other amounts in addition to or in lieu of the foregoing as may be
permitted by applicable California law. The term "rent", as used herein, is
defined as the minimum monthly installments of Base Monthly Rent and all other
sums required to be paid by Tenant pursuant to this Lease, all such other sums
being deemed as additional rent due hereunder. As used in (i) and (ii) above,
"worth at the time of award" shall be computed by allowing interest at a rate
equal to the discount rate of the Federal Reserve Bank of San Francisco plus
five (5%) percent per annum. As used in (iii) above, "worth at the time of
award" shall be computed by discounting such amount at the discount rate of the
Federal Reserve Bank of San Francisco at the time of award plus one (1%)
percent.

    B. RIGHT TO RE-ENTER: In the event of any such default by Tenant, Landlord
shall have the right, after terminating this Lease, to re-enter the Premises and
remove all persons and property. Such property may be removed and stored in a
public warehouse or elsewhere at the cost of and for the account of Tenant, and
disposed of by Landlord in any manner permitted by law.

    C. ABANDONMENT: If Landlord does not elect to terminate this Lease as
provided in Section 13.A or 13.B above, then the provisions of California Civil
Code Section 1951.4, (Landlord may continue the lease in effect after Tenant's
breach and abandonment and recover rent as it becomes due if Tenant has a right
to sublet and assign, subject only to reasonable limitations) as amended from
time to time, shall apply and Landlord may from time to time, without
terminating this Lease, either recover all rental as it becomes due or relet the
Premises or any part thereof for such term or terms and at such rental or
rentals and upon such other terms and conditions as Landlord in its sole
discretion may deem advisable, with the right to make alterations and repairs to
the Premises. In the event that Landlord elects to so relet, rentals received by
Landlord from such reletting shall be applied in the following order to: (i) the
payment of any indebtedness other than Base Monthly Rent due hereunder from
Tenant to Landlord; (ii) the payment of any cost of such reletting; (iii) the
payment of the cost of any alterations and repairs to the Premises; and (iv)

                                    Page 14
<PAGE>
the payment of Base Monthly Rent and other sums due and unpaid hereunder. The
residual rentals, if any, shall be held by Landlord and applied in payment of
future Base Monthly Rent as the same may become due and payable hereunder.
Landlord shall the obligation to market the space but shall have no obligation
to relet the Premises following a default if Landlord has other comparable
available space within the Building or Project. In the event the portion of
rentals received from such reletting which is applied to the payment of rent
hereunder during any month be less than the rent payable during that month by
Tenant hereunder, then Tenant shall pay such deficiency to Landlord immediately
upon demand. 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.

    D. NO TERMINATION: Landlord's re-entry or taking possession of the Premises
pursuant to 13.B or 13.C shall not be construed as an election to terminate this
Lease unless written notice of such intention is given to Tenant or unless the
termination is decreed by a court of competent jurisdiction. Notwithstanding any
reletting without termination by Landlord because of any default by Tenant,
Landlord may at any time after such reletting elect to terminate this Lease for
any such default.

    E. NON-WAIVER: Landlord may accept Tenant's payments without waiving any
rights under this Lease, including rights under a previously served notice of
default. No payment by Tenant or receipt by Landlord of a lesser amount than any
installment of rent due shall be deemed as other than payment on account of the
amount due. If Landlord accepts payments after serving a notice of default,
Landlord may nevertheless commence and pursue an action to enforce rights and
remedies under the previously served notice of default without giving Tenant any
further notice or demand. Furthermore, the Landlord's acceptance of rent from
the Tenant when the Tenant is holding over without express written consent does
not convert Tenant's Tenancy from a tenancy at sufferance to a month to month
tenancy. No waiver of any provision of this Lease shall be implied by any
failure of Landlord to enforce any remedy for the violation of that provision,
even if that violation continues or is repeated. Any waiver by Landlord of any
provision of this Lease must be in writing. Such waiver shall affect only the
provision specified and only for the time and in the manner stated in the
writing. No delay or omission in the exercise of any right or remedy by Landlord
shall impair such right or remedy or be construed as a waiver thereof by
Landlord. No act or conduct of Landlord, including, without limitation, the
acceptance of keys to the Premises, shall constitute acceptance of the surrender
of the Premises by Tenant before the Expiration Date. Only written notice from
Landlord to Tenant of acceptance shall constitute such acceptance of surrender
of the Premises. Landlord's consent to or approval of any act by Tenant which
requires Landlord's consent or approvals shall not be deemed to waive or render
unnecessary Landlord's consent to or approval of any subsequent act by Tenant.

    F. PERFORMANCE BY LANDLORD: If Tenant fails to perform any obligation
required under this Lease or by law or governmental regulation and such failure
continues beyond applicable notice and cure periods, Landlord in its sole
discretion may, after three (3) days' notice, without waiving any rights or
remedies and without releasing Tenant from its obligations hereunder, perform
such obligation, in which event Tenant shall pay Landlord as additional rent all
sums paid by Landlord in connection with such substitute performance, including
interest at the Agreed Interest Rate (as defined in Section 19.J) within ten
(10) days of Landlord's written notice for such payment.

14. LANDLORD'S  LIABILITY:

    A. LIMITATION ON LANDLORD'S LIABILITY: In the event of Landlord's failure to
perform any of its covenants or agreements under this Lease, Tenant shall give
Landlord written notice of such failure and shall give Landlord thirty (30) days
to cure or commence to cure such failure prior to any claim for breach or
resultant damages, provided, however, that if the nature

                                    Page 15
<PAGE>
of the default is such that it cannot reasonably be cured within the 30-day
period, Landlord shall not be deemed in default if it commences within such
period to cure, and thereafter diligently prosecutes the same to completion. In
addition, upon any such failure by Landlord, Tenant shall give notice by
registered or certified mail to any person or entity with a security interest in
the Premises ("Mortgagee") that has provided Tenant with notice of its interest
in the Premises, and shall provide Mortgagee a reasonable opportunity to cure
such failure, including such time to obtain possession of the Premises by power
of sale or judicial foreclosure, if such should prove necessary to effectuate a
cure. Tenant agrees that each of the Mortgagees to whom this Lease has been
assigned is an expressed third-party beneficiary hereof. Tenant waives any right
under California Civil Code Section 1950.7 or any other present or future law to
the collection of any payment or deposit from Mortgagee or any purchaser at a
foreclosure sale of Mortgagee's interest unless Mortgagee or such purchaser
shall have actually received and not refunded the applicable payment or deposit.
Tenant Further waives any right to terminate this Lease and to vacate the
Premises on Landlord's default under this Lease. Tenant's sole remedy on
Landlord's default is an action for damages or injunctive or declaratory relief.

    B. LIMITATION ON TENANT'S RECOURSE: If Landlord is a corporation, trust,
partnership, joint venture, unincorporated association or other form of business
entity, then (i) the obligations of Landlord shall not constitute personal
obligations of the officers, directors, trustees, partners, joint venturers,
members, owners, stockholders, or other principals or representatives except to
the extent of their interest in the Premises. Tenant shall have recourse only to
the interest of Landlord in the Premises or for the satisfaction of the
obligations of Landlord and shall not have recourse to any other assets of
Landlord for the satisfaction of such obligations.

    C. INDEMNIFICATION OF LANDLORD: Except to the extent due to the negligence
or willful misconduct of Landlord, as a material part of the consideration
rendered to Landlord, Tenant hereby waives all claims against Landlord for
damages to goods, wares and merchandise, and all other personal property in,
upon or about said Premises and for injuries to persons in or about said
Premises, from any cause arising at any time to the fullest extent permitted by
law, and Tenant shall indemnify, defend with counsel reasonably acceptable to
Landlord and hold Landlord, and their shareholders, directors, officers,
trustees, employees, partners, affiliates and agents from any claims,
liabilities, costs or expenses incurred or suffered arising from the use of
occupancy of the Premises or any part of the Project by Tenant or Tenant's
Agents, the acts or omissions of Tenant or Tenant's Agents, Tenant's breach of
this Lease, or any damage or injury to person or property from any cause, or
from the failure of Tenant to keep the Premises in good condition and repair as
herein provided,. Further, in the event Landlord is made party to any litigation
due to the acts or omission of Tenant or Tenant's Agents, Tenant will indemnify,
defend (with counsel reasonably acceptable to Landlord) and hold Landlord
harmless from any such claim or liability including Landlord's costs and
expenses and reasonable attorney's fees incurred in defending such claims.

Notwithstanding anything to the contrary in the Lease, (i) Tenant shall neither
release Landlord from, nor indemnify Landlord with respect to the active
negligence or willful misconduct of Landlord, or its agents, employees,
contractors or invitees, and (ii) Landlord shall indemnify and hold harmless
Tenant from all damages, liabilities, judgments, actions, attorneys' fees,
consultants' fees, cost and expenses arising from the active negligence or
willful misconduct of Landlord or its employees, agents, contractors or
invitees.

15. DESTRUCTION OF PREMISES:

    A. LANDLORD'S OBLIGATION TO RESTORE: In the event of a destruction of the
Premises during the Lease Term Landlord shall repair the same to a similar
condition to that which existed prior to such destruction. Such destruction
shall not annul or void this Lease; however, Tenant shall be entitled to a
proportionate reduction of Base Monthly Rent while repairs are being made,

                                    Page 16
<PAGE>
such proportionate reduction to be based upon the extent to which the repairs
interfere with Tenant's business in the Premises, as reasonably determined by
Landlord. In no event shall Landlord be required to replace or restore
Alterations, Tenant Improvements paid for by Tenant from sources other than the
Work Allowance or Tenant's fixtures or personal property.

    B. LIMITATIONS ON LANDLORD'S RESTORATION OBLIGATION: Notwithstanding the
provisions of Section 15.A, Landlord shall have no obligation to repair, or
restore the Premises if any of the following occur: (i) if the repairs cannot be
made in one hundred eighty (180) days from the date of receipt of all
governmental approvals necessary under the laws and regulations of State,
Federal, County or Municipal authorities, as reasonably determined by Landlord,
(ii) if the holder of the first deed of trust or mortgage encumbering the
Building elects not to permit the insurance proceeds payable upon damage or
destruction to be used for such repair or restoration, (iii) the damage or
destruction is not fully covered by the insurance maintained by Landlord
(excluding deductible amounts), (iv) the damage or destruction occurs in the
last eighteen (18) months of the Lease Term unless Tenant has exercised or
promptly exercises an option to extend the Lease Term, (v) Tenant is in default
pursuant to the provisions of Section 13, or (vi) Tenant has vacated the
Premises for more than one hundred twenty (120) days prior to such destruction.
In any such event Landlord may elect either to complete the repair or
restoration, or terminate this Lease by providing Tenant written notice of its
election within sixty (60) days following the damage or destruction. Tenant
shall also have the right to terminate this Lease in the event of either (i) or
(iv) above, by providing Landlord with written notice of its election to do so
within sixty (60) days following the damage or destruction.

16. CONDEMNATION: If any part of the Premises shall be taken for any public or
quasi-public use, under any statute or by right of eminent domain or private
purchase in lieu thereof, and only a part thereof remains which is susceptible
of occupation hereunder, this Lease shall, as to the part so taken, terminate as
of the day before title vests in the condemnor or purchaser ("Vesting Date") and
Base Monthly Rent payable hereunder shall be adjusted so that Tenant is required
to pay for the remainder of the Lease Term only such portion of Base Monthly
Rent as the value of the part remaining after such taking bears to the value of
the entire Premises prior to such taking. Further, in the event of such partial
taking, Landlord shall have the option to terminate this Lease as of the Vesting
Date. If all of the Premises or such part thereof be taken so that there does
not remain a portion susceptible for occupation hereunder, this Lease shall
terminate on the Vesting Date. If part or all of the Premises be taken, all
compensation awarded upon such taking shall go to Landlord, and Tenant shall
have no claim thereto; except Landlord shall cooperate with Tenant, without cost
to Landlord, to recover compensation for damage to or taking of any Alterations,
Tenant Improvements paid for by Tenant from sources other than the Work
Allowance, or for Tenant's moving costs. Tenant hereby waives the provisions of
California Code of Civil Procedures Section 1265.130 and any other similarly
enacted statue, and the provisions of this Section 16 shall govern in the case
of a taking.

Notwithstanding anything to the contrary in this Lease, if there is a taking
under the power of eminent domain (or a transfer in lieu thereof), Tenant shall
have the right to terminate the Lease if there is a taking of more than 33% of
the Building or more than 10% of the parking area. If any part of the Premises
is taken and this Lease is not terminated, then Landlord shall, to the extent
not prohibited by Law, repair any damage occasioned thereby to the remainder
thereof to a condition reasonably suitable for Tenant's continued operations.

17. ASSIGNMENT OR SUBLEASE:

    A. CONSENT BY LANDLORD: Except as specifically provided in this Section
17.E, Tenant may not assign, sublet, hypothecate, or allow a third party to use
the Premises without the express written consent of Landlord which shall not be
unreasonably withheld or delayed. In the event Tenant desires to assign this
Lease or any interest herein or sublet the Premises or any part

                                    Page 17
<PAGE>
thereof, Tenant shall deliver to Landlord (i) executed counterparts of any
agreement and of all ancillary agreements with the proposed assignee/subtenant,
(ii) current financial statements of the transferee covering the preceding three
years, (iii) the nature of the proposed transferee's business to be carried on
in the Premises, (iv) a statement outlining all consideration to be given on
account of the Transfer, and (v) a current financial statement of Tenant.
Landlord may condition its approval of any Transfer on receipt of a
certification from both Tenant and the proposed transferee of all consideration
to be paid to Tenant in connection with such Transfer. At Landlord's request,
Tenant shall also provide additional information reasonably required by Landlord
to determine whether it will consent to the proposed assignment or sublease.
Landlord shall have a fifteen (15) day period following receipt of all the
foregoing within which to notify Tenant in writing that Landlord elects to: (i)
terminate this Lease in the event the proposed sublease or assignment is for
substantially all of space in the Building and is for the substantially all the
remaining Lease Term; (ii) permit Tenant to assign or sublet such space to the
named assignee/subtenant on the terms and conditions set forth in the notice; or
(iii) refuse consent. If Landlord should fail to notify Tenant in writing of
such election within the 15-day period, Landlord shall be deemed to have elected
option (iii) above. In the event Landlord elects option (i) above, this Lease
shall expire with respect to such part of the Premises on the date upon which
the proposed sublease or transfer was to commence, and from such date forward,
Base Monthly Rent and Tenant's Allocable Share of all other costs and charges
shall be adjusted based upon the proportion that the rentable area of the
Premises remaining bears to the total rentable area of the Building. The
foregoing notwithstanding, in the event Landlord elects option (i) above, Tenant
shall have a three (3) day period in which to rescind the proposed sublease or
assignment. In the event Landlord elects option (ii) above, Landlord's written
consent to the proposed assignment or sublease shall not be unreasonably
withheld, provided and upon the condition that: (i) the proposed assignee or
subtenant is engaged in a business that is limited to the use expressly
permitted under this Lease; (ii) the proposed assignee or subtenant is a company
with sufficient financial worth and management ability to undertake the
financial obligation of this Lease and Landlord has been furnished with
reasonable proof thereof; (iii) the proposed assignment or sublease is in form
reasonably satisfactory to Landlord; (iv) the proposed sublease will not result
in there being greater than three (3) subtenants within the Premises at any time
during the Lease Term; and (v) Tenant reimburses Landlord on demand for any
costs that may be incurred by Landlord in connection with said assignment or
sublease, including the costs of making investigations as to the acceptability
of the proposed assignee or subtenant and legal costs incurred in connection
with the granting of any requested consent. In the event all or any one of the
foregoing conditions are not satisfied, Landlord shall be considered to have
acted reasonably if it withholds its consent. Tenant shall not have advertised
or publicized in any way the availability of the Premises without prior notice
to Landlord.

    B. ASSIGNMENT OR SUBLETTING CONSIDERATION: Landlord and Tenant hereby agree
that fifty percent (50%) of any rent or other economic consideration (i)
realized by Tenant under any sublease or assignment, or (ii) realized by any
subtenant under any sub-sublease of the Premises, in excess of the Base Monthly
Rent payable hereunder and reasonable subletting and assignment costs, shall be
paid to Landlord. Tenant's obligation to pay over Landlord's portion of the
consideration constitutes an obligation for additional rent hereunder. The above
provisions relating to Landlord's right to terminate the Lease and relating to
the allocation of excess rent are independently negotiated terms of the Lease
which constitute a material inducement for the Landlord to enter into the Lease,
and are agreed by the Parties to be commercially reasonable. No assignment or
subletting by Tenant shall relieve it of any obligation under this Lease. Any
assignment or subletting which conflicts with the provisions hereof shall be
void.

    C. NO RELEASE: Any assignment or sublease shall be made only if and shall
not be

                                    Page 18
<PAGE>
effective until the assignee or subtenant shall execute, acknowledge, and
deliver to Landlord an agreement, in form and substance satisfactory to
Landlord, whereby the assignee or subtenant shall assume all the obligations of
this Lease on the part of Tenant to be performed or observed and shall be
subject to all the covenants, agreements, terms, provisions and conditions in
this Lease. Notwithstanding any such sublease or assignment and the acceptance
of rent by Landlord from any subtenant or assignee, Tenant and any guarantor
shall remain fully liable for the payment of Base Monthly Rent and additional
rent due, and to become due hereunder, for the performance of all the covenants,
agreements, terms, provisions and conditions contained in this Lease on the part
of Tenant to be performed and for all acts and omissions of any licensee,
subtenant, assignee or any other person claiming under or through any subtenant
or assignee that shall be in violation of any of the terms and conditions of
this Lease, and any such violation shall be deemed a violation by Tenant. Tenant
shall indemnify, defend and hold Landlord harmless from and against all losses,
liabilities, damages, costs and expenses (including reasonable attorney fees)
resulting from any claims that may be made against Landlord by the proposed
assignee or subtenant or by any real estate brokers or other persons claiming
compensation in connection with the proposed assignment or sublease.

    D. REORGANIZATION OF TENANT: The provisions of this Section 17.D shall apply
if Tenant is a corporation and: (i) there is a dissolution, merger,
consolidation, or other reorganization of or affecting Tenant, where Tenant is
not the surviving corporation, or (ii) there is a sale or transfer to one person
or entity (or to any group of related persons or entities) of stock possessing
more than 50% of the total combined voting power of all classes of Tenant's
capital stock issued, outstanding and entitled to vote for the election of
directors, and after such sale or transfer of stock Tenant's stock is no longer
publicly traded. In a transaction under clause (i) the surviving corporation
shall promptly execute and deliver to Landlord an agreement in form reasonably
satisfactory to Landlord under which such surviving corporation assumes the
obligations of Tenant hereunder, and in a transaction under clause (ii) the
acquiring entity shall promptly execute and deliver to Landlord an agreement in
form reasonably satisfactory to Landlord under which such transferee or buyer
assumes the obligations of Tenant under the Lease (unless the acquiring entity
is a subsidiary created for the acquisition in which event the parent of the
acquiring entity shall assume the obligations of Tenant under this Lease).

    E. PERMITTED TRANSFERS: Notwithstanding anything contained in this Section
17, so long as Tenant complies with the provisions of this Section 17.E., Tenant
may enter into any of the following transfers (a "Permitted Transfer") without
Landlord's prior consent, and Landlord shall not be entitled to terminate the
Lease or to receive any part of any subrent resulting therefrom that would
otherwise be due pursuant to Sections 17.A and 17.B. Tenant may sublease all or
part of the Premises or assign its interest in this Lease to (i) any corporation
which controls, is controlled by, or is under common control with the original
Tenant to this Lease by means of an ownership interest of more than 50%; (ii) a
corporation which results from a merger, consolidation or other reorganization
in which Tenant is not the surviving corporation, so long as the surviving
corporation has a net worth at the time of such assignment that is equal to or
greater than the net worth of Tenant immediately prior to such transaction; and
(iii) a corporation which purchases or otherwise acquires all or substantially
all of the assets of Tenant so long as such acquiring corporation has a net
worth at the time of such assignment that is equal to or greater than the net
worth of Tenant immediately prior to such transaction.

The foregoing notwithstanding, Landlord acknowledges that Tenant may change its
current status as a California corporation to a Delaware corporation, and
Landlord hereby consents to and shall not hinder or otherwise interfere with
such change.

    F. EFFECT OF DEFAULT: In the event of Tenant's default, Tenant hereby
assigns all rents due from any assignment or subletting to Landlord as security
for performance of its

                                    Page 19
<PAGE>
obligations under this Lease, and Landlord may collect such rents as Tenant's
Attorney-in-Fact, except that Tenant may collect such rents unless a default
occurs as described in Section 13 above. A termination of the Lease due to
Tenant's default shall not automatically terminate an assignment or sublease
then in existence; rather at Landlord's election, such assignment or sublease
shall survive the Lease termination, the assignee or subtenant shall attorn to
Landlord, and Landlord shall undertake the obligations of Tenant under the
sublease or assignment; except that Landlord shall not be liable for prepaid
rent, security deposits or other defaults of Tenant to the subtenant or
assignee, or for any acts or omissions of Tenant and Tenant's Agents.

    G. CONVEYANCE BY LANDLORD: As used in this Lease, the term "Landlord" is
defined only as the owner for the time being of the Premises, so that in the
event of any sale or other conveyance of the Premises or in the event of a
master lease of the Premises, Landlord shall be entirely freed and relieved of
all its covenants and obligations hereunder, and it shall be deemed and
construed, without further agreement between the Parties and the purchaser at
any such sale or the master tenant of the Premises, that the purchaser or master
tenant of the Premises has assumed and agreed to carry out any and all covenants
and obligations of Landlord hereunder. Such transferor shall transfer and
deliver Tenant's security deposit to the purchaser at any such sale or the
master tenant of the Premises, and thereupon the transferor shall be discharged
from any further liability in reference thereto.

    H. SUCCESSORS AND ASSIGNS: Subject to the provisions this Section 17, the
covenants and conditions of this Lease shall apply to and bind the heirs,
successors, executors, administrators and assigns of all Parties hereto; and all
Parties hereto comprising Tenant shall be jointly and severally liable
hereunder.

18. OPTION TO EXTEND THE LEASE TERM:

    A. GRANT AND EXERCISE OF OPTION: Provided the tenant in possession of
Building 1 exercises its option to extend its lease term, then Landlord grants
to Tenant, subject to the terms and conditions set forth in this Section 18.A,
an option ("Options") to extend the Lease Term for an additional term (the
"Option Term"), which term shall be for a period of sixty (60) months and shall
be exercised, if at all, by written notice to Landlord no earlier than fifteen
(15) months prior to the date the Lease Term would expire but for such exercise
but no later than nine (9) months prior to the date the Lease Term would expire
but for such exercise, time being of the essence for the giving of such notice.
If Tenant exercises the Option, all of the terms, covenants and conditions of
this Lease shall apply except for the grant of additional Options pursuant to
this Section, provided that Base Monthly Rent for the Premises payable by Tenant
during the Option Term shall be the greater of (i) the average Base Monthly Rent
paid by Tenant during the initial Lease Term, and (ii) ninety five percent (95%)
of the Fair Market Rental as hereinafter defined. Notwithstanding anything
herein to the contrary, if Tenant is in monetary or material non-monetary
default under any of the terms, covenants or conditions of this Lease (beyond
applicable notice and cure periods) either at the time Tenant exercises the
Option or at any time thereafter prior to the commencement date of the Option
Term, then Landlord shall have, in addition to all of Landlord's other rights
and remedies provided in this Lease, the right to terminate the Option upon
notice to Tenant, in which event the Lease Term shall not be extended pursuant
to this Section 18.A. As used herein, the term "Fair Market Rental" is defined
as the rental and all other monetary payments, including any escalations and
adjustments thereto (including without limitation Consumer Price Indexing) that
Landlord could obtain during the Option Term from a third party desiring to
lease the Premises, based upon the current use and other potential uses of the
Premises, as determined by the rents then obtainable for new leases of space
comparable in age and quality to the Premises in the same real estate submarket
as the Building. The appraisers shall be instructed that the foregoing five
percent (5.0%) discount is intended to offset comparable rents that include the
following costs which Landlord will not incur in the event Tenant exercises its
option (i) brokerage commissions, (ii) tenant improvement

                                    Page 20
<PAGE>
allowances, (iii) building improvement costs, and (iv) vacancy costs.

The foregoing notwithstanding, in the event the tenant in possession of Building
1 does not exercise its option to extend its Lease Term, then Tenant's Option as
set forth in this Lease section 18.A. shall only be exercisable by Tenant if
Tenant simultaneously commits to lease Building 1 at 95% of the then fair market
rental rate and for a five year term, and otherwise under the same terms and
conditions of this Lease.

    B. DETERMINATION OF FAIR MARKET RENTAL: If Tenant exercises the Option,
Landlord shall send Tenant a notice setting forth the Fair Market Rental for the
Option Term within thirty (30) days following the Exercise Date. If Tenant
disputes Landlord's determination of Fair Market Rental for the Option Term,
Tenant shall, within thirty (30) days after the date of Landlord's notice
setting forth Fair Market Rental for the Option Term, send to Landlord a notice
stating that Tenant either elects to terminate its exercise of the Option, in
which event the Option shall lapse and this Lease shall terminate on the
Expiration Date, or that Tenant disagrees with Landlord's determination of Fair
Market Rental for the Option Term and elects to resolve the disagreement as
provided in Section 18.C below. If Tenant does not send Landlord a notice as
provided in the previous sentence, Landlord's determination of Fair Market
Rental shall be the Base Monthly Rent payable by Tenant during the Option Term.
If Tenant elects to resolve the disagreement as provided in Section 18.C and
such procedures are not concluded prior to the commencement date of the Option
Term, Tenant shall pay to Landlord as Base Monthly Rent the Fair Market Rental
as determined by Landlord in the manner provided above. If the Fair Market
Rental as finally determined pursuant to Section 18.C is greater than Landlord's
determination, Tenant shall pay Landlord the difference between the amount paid
by Tenant and the Fair Market Rental as so determined in Section 18.C within
thirty (30) days after such determination. If the Fair Market Rental as finally
determined in Section 18.C is less than Landlord's determination, the difference
between the amount paid by Tenant and the Fair Market Rental as so determined in
Section 18.C shall be credited against the next installments of Base Monthly
Rent due from Tenant to Landlord hereunder.

    C. RESOLUTION OF A DISAGREEMENT OVER THE FAIR MARKET RENTAL: Any
disagreement regarding Fair Market Rental shall be resolved as follows:

        1. Within thirty (30) days after Tenant's response to Landlord's notice
setting forth the Fair Market Rental, Landlord and Tenant shall meet at a
mutually agreeable time and place, in an attempt to resolve the disagreement.

        2. If within the 30-day period referred to above, Landlord and Tenant
cannot reach agreement as to Fair Market Rental, each party shall select one
appraiser to determine Fair Market Rental. Each such appraiser shall arrive at a
determination of Fair Market Rental and submit their conclusions to Landlord and
Tenant within thirty (30) days after the expiration of the 30-day consultation
period described above.

        3. If only one appraisal is submitted within the requisite time period,
it shall be deemed as Fair Market Rental. If both appraisals are submitted
within such time period and the two appraisals so submitted differ by less than
ten percent (10%), the average of the two shall be deemed as Fair Market Rental.
If the two appraisals differ by more than 10%, the appraisers shall immediately
select a third appraiser who shall, within thirty (30) days after his selection,
make and submit to Landlord and Tenant a determination of Fair Market Rental.
This third appraisal will then be averaged with the closer of the two previous
appraisals and the result shall be Fair Market Rental.

        4. All appraisers specified pursuant to this Section shall be members of
the American Institute of Real Estate Appraisers with not less than ten (10)
years experience appraising office and industrial properties in the Santa Clara
Valley. Each party shall pay the cost of the

                                    Page 21
<PAGE>
appraiser selected by such party and one-half of the cost of the third
appraiser.

    D. PERSONAL TO TENANT: All Options provided to Tenant in this Lease are
personal and granted to Netro Corporation or a permitted transferee pursuant to
Section 17.E. above and are not exercisable by any third party should Tenant
assign or sublet all or a portion of its rights under this Lease, unless
Landlord consents to permit exercise of any option by any assignee or subtenant,
in Landlord's sole and absolute discretion. In the event Tenant has multiple
options to extend this Lease, a later option to extend the Lease cannot be
exercised unless the prior option has been properly exercised.

19. GENERAL PROVISIONS:

    A. ATTORNEY'S FEES: In the event a suit or alternative form of dispute
resolution is brought for the possession of the Premises, for the recovery of
any sum due hereunder, to interpret the Lease, or because of the breach of any
other covenant herein; then the losing party shall pay to the prevailing party
reasonable attorney's fees including the expense of expert witnesses,
depositions and court testimony as part of its costs which shall be deemed to
have accrued on the commencement of such action. The prevailing party shall also
be entitled to recover all costs and expenses including reasonable attorney's
fees incurred in enforcing any judgment or award against the other party. The
foregoing provision relating to post-judgment costs is severable from all other
provisions of this Lease.

    B. AUTHORITY OF PARTIES: Tenant represents and warrants that it is duly
formed and in good standing, and is duly authorized to execute and deliver this
Lease on behalf of said corporation, in accordance with a duly adopted
resolution of the Board of Directors of said corporation or in accordance with
the by-laws of said corporation, and that this Lease is binding upon said
corporation in accordance with its terms. At Landlord's request, Tenant shall
provide Landlord with corporate resolutions or other proof in a form acceptable
to Landlord, authorizing the execution of the Lease.

    C. BROKERS: Tenant and Landlord each represent to the other that it has not
utilized or contacted a real estate broker or finder with respect to this Lease
other than CRESA Partners, which represents Tenant, and Tenant and Landlord each
agree to indemnify, defend and hold each other harmless against any claim, cost,
liability or cause of action asserted by any other broker or finder claiming
through the indemnifying party.

    D. CHOICE OF LAW: This Lease shall be governed by and construed in
accordance with California law. Except as provided in Section 19.E, venue shall
be Santa Clara County.

    E. DISPUTE RESOLUTION: Landlord and Tenant and any other party that may
become a party to this Lease or be deemed a party to this Lease including any
subtenants agree that, except for any claim by Landlord for unlawful detainer or
any claim within the jurisdiction of the small claims court (which small claims
court shall be the sole court of competent jurisdiction), any controversy,
dispute, or claim of whatever nature arising out of, in connection with or in
relation to the interpretation, performance or breach of this Lease, including
any claim based on contract, tort, or statute, shall be resolved at the request
of any party to this agreement through a two-step dispute resolution process
administered by J.A.M.S. or another judicial mediation service mutually
acceptable to the parties located in Santa Clara County, California. The dispute
resolution process shall involve first, mediation, followed, if necessary, by
final and binding arbitration administered by and in accordance with the then
existing rules and practices of J.A.M.S. or other judicial mediation service
selected. In the event of any dispute subject to this provision, either party
may initiate a request for mediation and the parties shall use reasonable
efforts to promptly select a J.A.M.S. mediator and commence the mediation. In
the event the parties are not able to agree on a mediator within thirty (30)
days, J. A. M. S. or another judicial mediation service mutually acceptable to
the parties shall appoint a mediator. The mediation shall be confidential and in
accordance with California Evidence Code Section 1119 et. seq. The mediation
shall be held

                                    Page 22
<PAGE>
in Santa Clara County, California and in accordance with the existing rules and
practice of J. A. M. S. (or other judicial and mediation service selected). The
parties shall use reasonable efforts to conclude the mediation within sixty (60)
days of the date of either party's request for mediation. The mediation shall be
held prior to any arbitration or court action (other than a claim by Landlord
for unlawful detainer or any claim within the jurisdiction of the small claims
court which are not subject to this mediation/arbitration provision and may be
filed directly with a court of competent jurisdiction). Should the prevailing
party in any dispute subject to this Section 19.E attempt an arbitration or a
court action before attempting to mediate, the prevailing party shall not be
entitled to attorney's fees that might otherwise be available to them in a court
action or arbitration and in addition thereto, the party who is determined by
the arbitrator to have resisted mediation, shall be sanctioned by the arbitrator
or judge.

IF A MEDIATION IS CONDUCTED BUT IS UNSUCCESSFUL, IT SHALL BE FOLLOWED BY FINAL
AND BINDING ARBITRATION ADMINISTERED BY AND IN ACCORDANCE WITH THE THEN EXISTING
RULES AND PRACTICES OF J.A.M.S. OR THE OTHER JUDICIAL AND MEDIATION SERVICE
SELECTED, AND JUDGMENT UPON ANY AWARD RENDERED BY THE ARBITRATOR(S) MAY BE
ENTERED BY ANY STATE OR FEDERAL COURT HAVING JURISDICTION THEREOF AS PROVIDED BY
CALIFORNIA CODE OF CIVIL PROCEDURE SECTION 1280 ET. SEQ, AS SAID STATUTES THEN
APPEAR, INCLUDING ANY AMENDMENTS TO SAID STATUTES OR SUCCESSORS TO SAID STATUTES
OR AMENDED STATUTES, EXCEPT THAT IN NO EVENT SHALL THE PARTIES BE ENTITLED TO
PROPOUND INTERROGATORIES OR REQUEST FOR ADMISSIONS DURING THE ARBITRATION
PROCESS. THE ARBITRATOR SHALL BE A RETIRED JUDGE OR A LICENSED CALIFORNIA
ATTORNEY. THE VENUE FOR ANY SUCH ARBITRATION OR MEDIATION SHALL BE IN SANTA
CLARA COUNTY, CALIFORNIA.

LANDLORD:  ______      TENANT:  _______

    F. ENTIRE AGREEMENT: This Lease and the exhibits attached hereto contain all
of the agreements and conditions made between the Parties hereto and may not be
modified orally or in any other manner other than by written agreement signed by
all parties hereto or their respective successors in interest. This Lease
supersedes and revokes all previous negotiations, letters of intent, lease
proposals, brochures, agreements, representations, promises, warranties, and
understandings, whether oral or in writing, between the parties or their
respective representatives or any other person purporting to represent Landlord
or Tenant.

    G. ENTRY BY LANDLORD: Upon prior notice to Tenant and subject to Tenant's
reasonable security regulations, Tenant shall permit

                                    Page 23
<PAGE>
Landlord and his agents to enter into and upon the Premises at all reasonable
times, and without any rent abatement or reduction or any liability to Tenant
for any loss of occupation or quiet enjoyment of the Premises thereby
occasioned, for the following purposes: (i) inspecting and maintaining the
Premises; (ii) making repairs, alterations or additions to the Premises; (iii)
erecting additional building(s) and improvements on the land where the Premises
are situated or on adjacent land owned by Landlord provided Landlord does not
unreasonably interfere with Tenant's use of or access to the Premises or
parking; (iv) performing any obligations of Landlord under the Lease including
remediation of Hazardous Materials if determined to be the responsibility of
Landlord provided Landlord does not unreasonably interfere with Tenant's use of
or access to the Premises or parking, (v) posting and keeping posted thereon
notices of non-responsibility for any construction, alteration or repair
thereof, as required or permitted by any law, and (vi) showing the Premises to
Landlord's or the Master Landlord's existing or potential successors, purchaser,
tenants and lenders. Tenant shall permit Landlord and his agents, at any time
within nine (9) months prior to the Expiration Date (or at any time during the
Lease if Tenant is in default hereunder), to place upon the Premises "For Lease"
signs and upon prior notice to Tenant any subject to Tenant's reasonable
security regulations, exhibit the Premises to real estate brokers and
prospective tenants at reasonable hours.

    H. ESTOPPEL CERTIFICATES: At any time during the Lease Term, Tenant shall,
within ten (10) days following written notice from Landlord, execute and deliver
to Landlord a written statement certifying, if true, the following: (i) that
this Lease is unmodified and in full force and effect (or, if modified, stating
the nature of such modification); (ii) the date to which rent and other charges
are paid in advance, if any; (iii) acknowledging that there are not, to Tenant's
knowledge, any uncured defaults on Landlord's part hereunder (or specifying such
defaults if they are claimed); and (iv) such other information as Landlord may
reasonably request. Any such statement may be conclusively relied upon by any
prospective purchaser or encumbrancer of Landlord's interest in the Premises.
Tenant's failure to deliver such statement within such time shall be conclusive
upon the Tenant that this Lease is in full force and effect without
modification, except as may be represented by Landlord, and that there are no
uncured defaults in Landlord's performance. Tenant agrees to provide, within
five (5) days of Landlord's request, Tenant's most recent three (3) years of
audited financial statements for Landlord's use in financing or sale of the
Premises or Landlord's interest therein.

    I. EXHIBITS: All exhibits referred to are attached to this Lease and
incorporated by reference.

    J. INTEREST: All rent due hereunder, if not paid within five (5) business
days that it is due, shall bear interest at the rate of the Reference Rate
published by Bank of America, San Francisco Branch, plus two percent (2%) per
annum from that date until paid in full ("Agreed Interest Rate"). This provision
shall survive the expiration or sooner termination of the Lease. Despite any
other provision of this Lease, the total liability for interest payments shall
not exceed the limits, if any, imposed by the usury laws of the State of
California. Any interest paid in excess of those limits shall be refunded to
Tenant by application of the amount of excess interest paid against any sums
outstanding in any order that Landlord requires. If the amount of excess
interest paid exceeds the sums outstanding, the portion exceeding those sums
shall be refunded in cash to Tenant by Landlord. To ascertain whether any
interest payable exceeds the limits imposed, any non-principal payment
(including late charges) shall be considered to the extent permitted by law to
be an expense or a fee, premium, or penalty rather than interest.

    K. MODIFICATIONS REQUIRED BY LENDER: If any lender of Landlord or ground
lessor of the Premises requires a modification of this Lease that will not
increase Tenant's cost or expense or materially or adversely change Tenant's
rights and obligations, this Lease shall be so modified and Tenant shall execute
whatever documents

                                    Page 24
<PAGE>
are required and deliver them to Landlord within ten (10) days after the
request.

    L. NO PRESUMPTION AGAINST DRAFTER: Landlord and Tenant understand, agree and
acknowledge that this Lease has been freely negotiated by both Parties; and that
in any controversy, dispute, or contest over the meaning, interpretation,
validity, or enforceability of this Lease or any of its terms or conditions,
there shall be no inference, presumption, or conclusion drawn whatsoever against
either party by virtue of that party having drafted this Lease or any portion
thereof.

    M. NOTICES: All notices, demands, requests, or consents required to be given
under this Lease shall be sent in writing by U.S. certified mail, return receipt
requested, or by personal delivery addressed to the party to be notified at the
address for such party specified in Section 1 of this Lease, or to such other
place as the party to be notified may from time to time designate by at least
fifteen (15) days prior notice to the notifying party. When this Lease requires
service of a notice, that notice shall replace rather than supplement any
equivalent or similar statutory notice, including any notices required by Code
of Civil Procedure Section 1161 or any similar or successor statute.

    N. This paragraph intentionally left blank.

    O. RENT: All monetary sums due from Tenant to Landlord under this Lease,
including, without limitation those referred to as "additional rent", shall be
deemed as rent.

    P. REPRESENTATIONS: Tenant acknowledges that neither Landlord nor any of its
employees or agents have made any agreements, representations, warranties or
promises with respect to the Premises or with respect to present or future
rents, expenses, operations, tenancies or any other matter. Except as herein
expressly set forth herein, Tenant relied on no statement of Landlord or its
employees or agents for that purpose.

    Q. RIGHTS AND REMEDIES: Subject to Section 14 above, All rights and remedies
hereunder are cumulative and not alternative to the extent permitted by law, and
are in addition to all other rights and remedies in law and in equity.

    R. SEVERABILITY: If any term or provision of this Lease is held
unenforceable or invalid by a court of competent jurisdiction, the remainder of
the Lease shall not be invalidated thereby but shall be enforceable in
accordance with its terms, omitting the invalid or unenforceable term.

    S. SUBMISSION OF LEASE: Submission of this document for examination or
signature by the parties does not constitute an option or offer to lease the
Premises on the terms in this document or a reservation of the Premises in favor
of Tenant. This document is not effective as a lease or otherwise until executed
and delivered by both Landlord and Tenant.

    T. SUBORDINATION: This Lease is subject and subordinate to ground and
underlying leases, mortgages and deeds of trust (collectively "Encumbrances")
which may now affect the Premises, to any covenants, conditions or restrictions
of record, and to all renewals, modifications, consolidations, replacements and
extensions thereof; provided, however, if the holder or holders of any such
Encumbrance ("Holder") require that this Lease be prior and superior thereto,
within seven (7) days after written request of Landlord to Tenant, Tenant shall
execute, have acknowledged and deliver all documents or instruments, in the form
presented to Tenant, which Landlord or Holder deems necessary or desirable for
such purposes. Landlord shall have the right to cause this Lease to be and
become and remain subject and subordinate to any and all Encumbrances which are
now or may hereafter be executed covering the Premises or any renewals,
modifications, consolidations, replacements or extensions thereof, for the full
amount of all advances made or to be made thereunder and without regard to the
time or character of such advances, together with interest thereon and subject
to all the terms and provisions thereof; provided only, that in the event of
termination of any such lease or upon the foreclosure of any such mortgage or
deed of trust, Holder agrees to recognize Tenant's rights under this Lease as
long as Tenant is not then in default and continues to

                                    Page 25
<PAGE>
pay Base Monthly Rent and additional rent and observes and performs all required
provisions of this Lease. Within ten (10) days after Landlord's written request,
Tenant shall execute any documents required by Landlord or the Holder to make
this Lease subordinate to any lien of the Encumbrance. If Tenant fails to do so,
then in addition to such failure constituting a default by Tenant, it shall be
deemed that this Lease is so subordinated to such Encumbrance. Notwithstanding
anything to the contrary in this Section, Tenant hereby attorns and agrees to
attorn to any entity purchasing or otherwise acquiring the Premises at any sale
or other proceeding or pursuant to the exercise of any other rights, powers or
remedies under such encumbrance.

Landlord shall cause the existing lender to furnish to Tenant, within sixty (60)
days of the date of both parties' execution of this Lease, with a written
agreement providing for (i) recognition by the lender of all of the terms and
conditions of this Lease; and (ii) continuation of this Lease upon foreclosure
of existing lender's security interest in the Premises. In the event that
Landlord is unable to provide such agreement, Tenant's sole remedy shall be
termination of the Lease, which election shall be made within fourteen (14) days
following the expiration of such sixty (60) day period.

    U. SURVIVAL OF INDEMNITIES: All indemnification, defense, and hold harmless
obligations of Landlord and Tenant under this Lease shall survive the expiration
or sooner termination of the Lease.

    V. TIME: Time is of the essence hereunder.

    W. WAIVER OF RIGHT TO JURY TRIAL: Landlord and Tenant waive their respective
rights to trial by jury of any contract or tort claim, counterclaim,
cross-complaint, or cause of action in any action, proceeding, or hearing
brought by either party against the other on any matter arising out of or in any
way connected with this Lease, the relationship of Landlord and Tenant, or
Tenant's use or occupancy of the Premises, including any claim of injury or
damage or the enforcement of any remedy under any current or future law,
statute, regulation, code, or ordinance.

    X. TENANT'S RIGHT TO CANCEL THE LEASE: Notwithstanding Tenant's execution of
