                           LEASE TERMINATION AGREEMENT

        This LEASE TERMINATION AGREEMENT ("Agreement") is made and entered into
as of September 5, 2002, by and between PARKSIDE TOWERS CO-TENANCY, a tenancy in
common between GATEWAY PHOENIX ASSOCIATES, L.P., a California limited
partnership, and 5990 SEPULVEDA ASSOCIATES, L.P., a California limited
partnership ("LANDLORD"), EOP OPERATING LIMITED PARTNERSHIP, a Delaware limited
partnership ("EOP"), and INKTOMI CORPORATION, a Delaware corporation ("TENANT").

                                R E C I T A L S :

        A. Landlord and Tenant entered into that certain First Amended and
Restated Lease Agreement (the "OFFICE LEASE"), dated as of March 10, 2000,
whereby Landlord leased to Tenant and Tenant leased from Landlord approximately
398,460 rentable square feet of space (collectively the "PREMISES") located in
the East Office Building, the West Office Building, and the First Level Office
Space (as more particularly defined in the Lease), in the office project located
at 1001 East Hillsdale Boulevard, Foster City, California (the "PROJECT").

        B. The Office Lease, as previously amended by that certain First
Amendment to First Amended and Restated Lease Agreement (the "FIRST AMENDMENT")
dated as of May 31, 2001, is herein referred to as the "LEASE".

        C. Landlord and Tenant desire to enter into this Agreement in order to
terminate the Lease and to release one another from their respective obligations
thereunder, except as otherwise provided herein. EOP directly or indirectly owns
and controls Landlord, and directly or through controlled affiliates may hold
some interest in the Project or the Lease, and therefore joins in this Agreement
to bind itself as herein provided.

        D. Concurrently herewith, Landlord, EOP and Tenant have entered into
that certain Participation and Put Option Agreement (the "PARTICIPATION
AGREEMENT").

        E. Concurrently herewith, Tenant has delivered to First American Title
Company (the "ESCROW HOLDER") the "Note", the "Note Deed of Trust", the "Bill of
Sale," and the "Participation Deed of Trust", as those terms are defined in this
Agreement, as required by the terms of this Agreement and the Participation
Agreement. The Note Deed of Trust and the Participation Deed of Trust are
referred to herein collectively as the "RECORDABLE DOCUMENTS".

        F. Subject to the satisfaction or waiver of the "Termination
Conditions," as defined in Section 6.1 below, the Escrow Holder will on or
promptly after the "Lease Termination Date," as defined in Section 2 below,
cause the Recordable Documents to be recorded in the Official Records of San
Mateo County.

                               A G R E E M E N T :

        NOW, THEREFORE, in consideration of the foregoing recitals and the
mutual covenants contained herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto hereby agree as follows:

        1. CAPITALIZED TERMS. All undefined terms when used herein shall have
the same respective meanings as are given such terms in the Lease unless
expressly provided otherwise in this Agreement.

        2. TERMINATION OF LEASE. The Lease shall terminate and be of no further
force or effect effective as of the date of full execution and delivery by
Landlord, EOP and Tenant of this Agreement and the satisfaction or waiver of the
Termination Conditions (the "LEASE TERMINATION DATE").

               2.1 SURRENDER OF PREMISES. Tenant shall vacate the Premises and
surrender and deliver exclusive possession thereof to Landlord on or before the
Lease Termination Date. Tenant shall surrender possession of the Premises, and
Landlord shall accept such surrender, in the same physical condition as exists
on the date of this Agreement, absolutely "AS IS" and "WITH ALL FAULTS."

reimbursement with respect to any of the "Base Building Changes", as that term
is defined in Section 1 of the First Amendment. Tenant further agrees that,
subject to satisfaction or waiver of the Termination Conditions, Landlord shall

Agreement or the Bill of Sale. Tenant represents to Landlord that as of the
Termination Date, there are no storage or other costs outstanding with respect
to the HVAC chillers. Landlord shall bear all costs of storing the chillers
after the Lease Termination Date, as well as costs of moving and installing the
chillers.

               2.2 CONTINUING LIABILITY. Notwithstanding the termination of the
Lease and the release of liability pursuant to Section 7 of this Agreement,
Tenant shall remain liable, with respect to the period of its tenancy prior to

below; (iii) Tenant has the full right, legal power and actual authority to
enter into this Agreement and the "Operative Documents," as defined in Section

date hereof there are no, and as of the Lease Termination Date there shall not
be any, mechanic's liens or other liens encumbering all or any portion of the

legal power and actual authority to enter into this Agreement and the Operative
Documents and to terminate the Lease.

                      2.3.3 Survival. Notwithstanding the termination of the
Lease and the release of liability provided for herein, the representations and
warranties set forth in this Section 2.3 shall survive the Lease Termination
Date and each shall be liable for any material inaccuracy or breach thereof.

paid Base Rent, and estimated Operating Costs and Taxes attributable to the
month of August, 2002, in the amount of $1,663,855.11 (collectively, the "AUGUST

                    NOTE SECURED BY FIRST LIEN DEED OF TRUST

$21,500,000.00         Foster City, California         Dated:  September 5, 2002

        FOR VALUE RECEIVED, the undersigned INKTOMI CORPORATION, a Delaware
corporation ("Maker"), agrees and promises to pay to the order of PARKSIDE
TOWERS CO-TENANCY, a tenancy-in-common between GATEWAY PHOENIX ASSOCIATES, L.P.,
a California limited partnership, and 5990 SEPULVEDA ASSOCIATES, L.P., a
California limited partnership (collectively, "Lender"), at such place or places
as the Lender or other holder hereof may from time to time designate in writing,
the principal sum of Twenty One Million Five Hundred Thousand Dollars
($21,500,000.00). Maker agrees that such principal sum may be increased by
$16,478,291.00, to a total initial principal balance of $37,978,291.00, pursuant
to the terms of Section 6.5 of that certain "Lease Termination Agreement" among
Holder, Maker, and EOP Operating Limited Partnership ("EOP"), dated of even date
herewith. Holder hereby agrees that the principal balance of this Note may be
reduced by up to $1,125,000.00 (the "In Lieu Deposit Amount") in the event of a
default by EOP or its assignee under that certain "Put Purchase Agreement" as
defined in that certain "Participation Agreement" among Holder, Maker and EOP,
and dated of even date herewith, if the "Buyer", as defined in the Put Purchase
Agreement elects not to pay the Deposit. Additionally, in the event such
reduction of the principal balance by the In Lieu Deposit Amount occurs, no
interest shall be deemed to have accrued on such In Lieu Deposit Amount for the
period between the "Agreement Date", as defined in the Put Purchase Agreement,
and the date of such reduction.

        Five Million Dollars ($5,000,000.00) of the principal balance hereunder
shall be paid to Lender on or before October 1, 2002 (the "Initial Principal
Payment"). A final installment covering the entire remaining principal balance
and interest accrued thereon shall be due and payable on the date (the "Maturity
Date") which is the earlier of (i) January 21, 2003 (provided that if Maker
exercises the "Put Option", as provided in the Participation Agreement, such
Maturity Date shall be extended to be the date of the Closing of the sale under
the Put Purchase Agreement, or the date of termination of the Put Purchase
Agreement, subject to the possible further extension of the Maturity Date to
June 30, 2003, pursuant to Section 4.5 of the Participation Agreement), and (ii)
the date a "Liquidity Event", as that term is defined in the Participation
Agreement, occurs.

        If Maker timely makes the Initial Principal Payment, no interest shall
be deemed to have accrued on such amount, and no interest shall commence to
accrue upon the remaining outstanding principal balance of this Note until
January 1, 2003, at which time interest shall commence to accrue on the
outstanding principal balance hereof from time to time remaining unpaid until
maturity at the rate of six percent (6.00%) per annum (the "Interest Rate").. If
Maker fails to make the Initial Principal Payment as set forth herein, the total
principal balance of this Note, including the Initial Principal Payment shall be
deemed to have retroactively accrued interest from the date of this Note, and
shall continue to accrue interest until paid, at the

<PAGE>

"Default Rate", defined below, and the entire outstanding principal balance
hereof shall, at the election of the Lender or other holder hereof, become
immediately due and payable. Notwithstanding the foregoing, with respect to the
payment of the Initial Principal Payment only, Lender shall not accelerate the
entire outstanding principal balance of this Note unless and until Maker has
failed to cure such delinquency by October 8, 2002.

        Maker shall pay accrued interest under this Note, at the Interest Rate
or Default Rate as the case may be, in arrears, on or before the first of each
month commencing after the date interest begins to accrue hereon. Each payment
shall be made by wire transfer payable to Lender and sent to the following
account:

        Bank of America
        Dallas, TX
        Bank ABA Number:  111000012
        Account Name:  EOP Operating Limited Partnership
        Account Number:  3750783137

        The principal evidenced hereby may be prepaid in whole or in part at any
time without penalty or premium.

        All sums due under this Note and that certain First Lien Leasehold and
Fee Deed of Trust With Assignment of Rents and Fixture Filing (the "Deed of
Trust") securing same are payable at the place or places as above stated in
legal tender of the United States of America current on the dates such sums or
payments are respectively due. Any remittances by check or draft shall be
credited on the date of receipt subject to the condition that such check or
draft may be handled for collection in accordance with the practice of the
collecting bank or banks and any receipt issued therefor shall be void unless
the amount due is actually received by the Lender or other holder hereof.

        If any installment payment herein provided for, or any part thereof, is
not paid when due, each and every such defaulted installment, or part thereof,
shall bear simple interest at rate (the "Default Rate") which is the lesser of
(i) of ten percent (10%) per annum in excess of the then current interest rate
of this Note, and (ii) the maximum rate permitted by applicable law, from its
due date until date of payment.

        During the existence of any default or delinquency under the terms of
this Note or under the terms of the Deed of Trust or other instruments given as
a security for and which secure this Note, the Lender or other holder hereof is
hereby expressly authorized to apply all payments made on this Note to the
payment of such part of any delinquency as it may elect.

        If default be made in the payment of the whole or any part of any of the
several installments of this Note when due, then, or at any time thereafter
during the continuance of any such default, the entire unpaid principal balance
of this Note together with any interest accrued thereon, shall, at the election
of the Lender or other holder hereof, and without notice of such election and
without demand or presentment, become immediately due and payable at the place

<PAGE>

of payment aforesaid, and the principal balance together with any interest
accrued thereon, so accelerated and declared due as aforesaid, shall thereafter
bear simple interest at the Default Rate until paid.

        If any default be made as hereinabove set forth, the failure of the
Lender or other holder hereof promptly to exercise its right to declare the
indebtedness remaining unpaid hereunder to be immediately due and payable or the
acceptance of one or more installments from any person thereafter, shall not
constitute a waiver of such right while any default continues nor a waiver of
such right in connection with any future default.

        The Deed of Trust of even date herewith which secures the obligations of
this Note contains provisions which restrict the right to transfer or further
encumber the property described in said Deed of Trust.

        Maker hereby waives diligence, demand, presentment for payment, and
notice of whatever kind or nature. Without discharging or in any way affecting
the liability of the undersigned, the undersigned hereby consents to any and all
extensions of this Note as Lender may in its sole discretion grant from time to
time, to the release of all or any part of the security for the payment hereof
and to the release of any party liable for repayment of the obligations
hereunder. If more than one person or entity is executing this Note then all of
the obligations herein contained shall be considered the joint and several
obligations of each of the undersigned.

        This Note shall be governed by the laws of the State of California,
except to the extent that Federal laws may preempt the laws of the State of
California.

        In the event that this Note is placed in the hands of an attorney at law
for collection after maturity or upon default or in the event that proceedings
at law or in equity are instituted in connection herewith, or in the event that
this Note is placed in the hands of an attorney at law to enforce any of the
rights or the agreements contained herein, Maker shall pay all costs of
collecting or attempting to collect this Note or protecting or enforcing such
rights, including, without limitation, reasonable attorneys' fees.

        This Note is subject to the limitation that in no event shall interest
or any other amount paid or agreed to be paid to Lender for the use, forbearance
or detention of money to be advanced hereunder exceed the highest lawful rate
permissible under applicable usury laws. If fulfillment of any provision hereof
shall be deemed by a court of competent and final jurisdiction to violate any
applicable usury restrictions then ipso facto, the obligation to be fulfilled
shall be reduced to the limit of such validity, and any amount received in
excess of such limit shall be applied to reduce the unpaid principal balance
hereof and not to the payment of interest.

under or upon the Subject Property, all development rights or credits and air
rights, all fixtures, all additions and accretions thereto, and any greater
estate in the Subject Property or any part thereof now owned or hereafter
acquired by Trustor. Trustor makes the foregoing grant to Trustee to hold the
Subject Property in trust for the benefit of Beneficiary, and for the purpose
and upon the terms and conditions hereinafter set forth.

                                       II.

                               ASSIGNMENT OF RENTS

        2.01 Trustor absolutely and irrevocably assigns to Beneficiary the
rents, issues, deposits and profits of the Subject Property, together with the
immediate and continuing right to collect and receive the same, for the purposes
and upon the terms and conditions hereinafter set

                                     -1-

forth. The foregoing assignment shall not impose upon Beneficiary any duty to
produce rents from the Subject Property, and said assignment shall not cause
Beneficiary to be a "mortgagee in possession" for any purpose.

                                      III.

                                 FIXTURE FILING

        3.01 This Deed of Trust encumbers, and Trustor hereby grants Beneficiary
a security interest in, all personal property of any kind whatsoever, which is
now or becomes a "fixture" and which is used or will be used in construction of,
or is or will be placed upon or is derived from or used in any connection with
the use, occupancy or enjoyment of, the Subject Property. "Fixtures" shall
include all articles of personal property, furniture and furnishings which are
so related to the Subject Property such that an interest arises in them under
the real estate laws of the State of California. To the extent of the existence
of personal property encumbered by the Deed of Trust, this Deed of Trust
constitutes a security agreement and is intended to create a security interest
in such personal property in favor of Beneficiary and to constitute a "fixture
filing" in accordance with the provisions of Section 9313 of the Uniform
Commercial Code in effect in the State of California. This Deed of Trust shall
be self-operative with respect to such personal property, but Trustor agrees to
execute and deliver on demand such security agreements, financing statements and
other instruments as Beneficiary may request in order to impose the lien hereof
more specifically upon any of such property.

                                       IV.

                               OBLIGATIONS SECURED

        Trustor makes the foregoing grant and assignment for the purpose of
securing the following obligations which Trustor covenants to pay and perform
promptly in accordance with their terms:

        4.01 Payment to Beneficiary of all indebtedness evidenced by and arising
under that certain Note Secured by First Lien Deed of Trust (the "Note"), dated
as of the date hereof, payable to Beneficiary or its order, in the principal
amount of Twenty One Million Five Hundred Thousand Dollars ($21,500,000.00)
(which principal amount may be increased by $16,478,291.00 to a total of
$37,978,291.00 pursuant to the terms of the Note), which Note is incorporated
herein by this reference, together with interest thereon, and any modifications,
extensions or renewals thereof (including, but without limitation (i)
modifications of the required principal and/or interest payment dates, deferring
or accelerating said payment dates in whole or in part, and/or (ii)
modifications, extensions or renewals at a different rate of interest), whether
or not any such modification, extension or renewal is evidenced by a new or
additional promissory note or notes;

        4.02 Payment to Beneficiary of all indebtedness or such further sums
and/or performance of such further obligations as Trustor may undertake to pay
and/or perform (whether as principal, surety or guarantor) for the benefit of
Beneficiary, its successors or

                                     -2-
<PAGE>

assigns, when said borrowings and/or obligations are evidenced by a writing or
writings reciting that they are so secured; and

        4.03 Performance of each agreement of Trustor herein contained or
contained in the Note, and the payment of each fee, cost and expense by Trustor
as herein set forth.

        TO PROTECT THE SECURITY OF THIS DEED OF TRUST, THE PARTIES AGREE AS
FOLLOWS:

                                       V.

                        RIGHTS AND DUTIES OF THE PARTIES.

        5.01 Warranties by Trustor. Trustor is a corporation duly organized and
existing under the laws of the State of Delaware and qualified to do business in
the State of California. Trustor warrants that Trustor is the lawful owner of
the Subject Property in fee simple, without limitation on its right to encumber.

        5.02 Taxes and Assessments. Trustor shall pay or cause to be paid prior
to delinquency all real property taxes, assessments, levies and charges imposed
by any public or quasi-public authority or utility company which are or may
become a lien upon the Subject Property, any part thereof or interest therein.
Trustor shall also pay when due all real property taxes, assessments, levies and
charges imposed by any public authority upon Beneficiary by reason of its
interest in the Subject Property created hereby; provided, however, that Trustor
shall have no obligation to pay or discharge taxes which may be imposed from
time to time upon Beneficiary and which are measured by and imposed upon
Beneficiary's net income. Upon written request of Beneficiary, Trustor shall
provide Beneficiary with evidence of such payment. Trustor shall have the right
to contest in good faith any such real property taxes, assessments, levies or
charges provided that it does so diligently and without prejudice to
Beneficiary.

        As used herein, the term "real property taxes" shall include any form of
assessment, possessory interest tax, license fee, license tax, business license
fee, business license tax, commercial rental tax, levy, charge, penalty, tax or
similar imposition imposed by any authority having the direct power to tax,
including any city, county, state or federal government, or any school,
agricultural, lighting, drainage or other improvement or special assessment
district thereof, as against any legal or equitable interest of Trustor in the
Subject Property, including, but not limited to, the following:

        (a) Any assessment, tax, fee, levy or charge in substitution, partially
        or totally, of any assessment, tax, fee, levy or charge previously
        included within the definition of real property tax. It is the intention
        of Trustor and Beneficiary that all such new and increased assessments,
        taxes, fees, levies and charges and all similar assessments, taxes,
        fees, levies and charges be included within the definition of real
        property taxes for the purposes of this Deed of Trust;

        (b) Any assessment, tax, fee, levy or charge allocable to the operation
        of or measured by the area of the Subject Property, including, without
        limitation, any gross income tax or excise tax levied in lieu of real
        property taxes by the state, city or federal government, or any
        political subdivision thereof, with respect to the

                                     -3-
<PAGE>

        possession, leasing, operating, management, maintenance, alteration,
        repair, use or occupancy of the Subject Property, or any portion
        thereof; and

        (c) Any assessment, tax, fee, levy or charge upon this transaction or
        any document creating or transferring any interest or an estate in the
        Subject Property.

        5.03 Impounds for Insurance Premiums and Taxes. After the occurrence of
an Event of Default, at Beneficiary's option, Trustor shall pay to Beneficiary
monthly, on or before the fifth (5th) date of each month, 1/12 of such amount as
Beneficiary from time to time estimates will be required to pay all taxes
required to be paid by Paragraph 5.02 and insurance premiums for insurance
required by Paragraph 5.04. Beneficiary's estimates shall be based on the
amounts actually payable or, if unknown, on the amounts actually paid for the
year preceding that for which such payments are being made. Any deficiencies
shall be promptly paid by Trustor to Beneficiary on demand. Trustor shall
transmit bills for the taxes and insurance premiums as soon as received. When
Beneficiary has received from Trustor or on its account funds sufficient to pay
the same, Beneficiary shall pay such bills. If the amount paid by Trustor in any
year exceeds the aggregate required, such excess shall be applied to impound
payments for the succeeding year. Beneficiary shall not be a trustee of funds in
said account and may commingle such funds with its general assets without any
obligation to pay interest thereon or account for any earnings, income or
interest on such funds.

        5.04 Insurance. Trustor shall at all times provide, maintain and keep in
force (i) commercial general public liability in the amount of at least
$5,000,000.00 and property damage coverage with a broad form coverage
endorsement and also breach of warranty coverage; (ii) protection against fire,
"extended coverage" and other "all risk" perils, including earthquake, and, if
the improvements are located in a flood hazard area, flood insurance on the
improvements, all in an amount equal to the full replacement value of all real
and personal property and improvements as determined by Beneficiary; (iii) rent
loss insurance in the amount of gross pro forma income for twelve (12) months;
(iv) insurance against loss or damage from leakage of sprinkler systems, air
conditioning equipment or other equipment now or hereafter installed in or on
the Subject Property; (v) during the course of any construction of or repairs to
the improvements or personal property, builders course of construction and
completed value insuring each name insured against "all risks of physical loss"
and worker's compensation insurance and any other employee benefit insurance
required by law, for all employees of Trustor engaged on or with respect to the
Subject Property in such amount as is reasonably satisfactory to Beneficiary, or
if such limits are established by law, in such amounts; and (vi) such other
insurance as Beneficiary may reasonably require insuring against loss which at
the time is commonly insured against and generally available at commercially
reasonable rates in the case of premises similarly situated, with due regard
being given to the height and type of improvements, the personal property and
the location, construction, use and occupancy thereof.

        5.05 Terms of Insurance. All policies of insurance required by the terms
of this Deed of Trust, or otherwise carried by Trustor and applicable to the
Property (except the employee benefit and public liability insurance which shall
name Beneficiary as an additional insured) shall contain a lender's loss payable
endorsement for the benefit of Beneficiary, which shall provide that (i) all
insurance proceeds shall be paid to Beneficiary and Beneficiary shall be
authorized and empowered by Trustor to settle, adjust or compromise any claims
for loss, damage or destruction under such policies of insurance, (ii) any loss
covered by such insurance

                                     -4-
<PAGE>

shall be payable by the insurer in accordance with the terms of such policy
notwithstanding any act or negligence of Trustor, its agents or employees, the
named insured, or any owner, tenant, or occupant of the Subject Property which
might otherwise result in forfeiture of said insurance, (iii) the insurer waives
all rights of setoff, counterclaim or deduction against Trustor, and (iv) should
legal title to and beneficial ownership of the Subject Property become vested in
Beneficiary, the insurance provided by such policies shall continue for the term
thereof for the benefit of Beneficiary. All required insurance shall provide (i)
a waiver of subrogation endorsement in a form satisfactory to Beneficiary; (ii)
the insurance afforded all parties named as insured shall be primary insurance
and shall not participate with, nor be in excess over, any other valid and
collectible insurance available to Beneficiary; (iii) any other insurance
obtained by any named insured shall not be called upon to contribute until the
limits of the policies required hereunder are exhausted; (iv) the insurance
required hereunder cannot be cancelled or materially amended or altered without
at least thirty (30) days prior written notice to Beneficiary; and (v) the
insurer shall notify Beneficiary, within thirty (30) days prior to the
expiration of any policy, of Trustor's failure to renew such policy; and (vi)
with respect to the fire and "extended coverage" insurance, a replacement cost
endorsement, an agreed amount endorsement, and an inflation guard endorsement,
all in a form satisfactory to Beneficiary. All insurance required hereunder
shall be issued by companies approved in advance by Beneficiary and rated at
least A-VIII by a current Best's Insurance Guide, and such insurance shall be in
the form and on terms (including but not limited to deductibles, self-insured
retentions, or similar provisions) reasonably approved in advance by
Beneficiary.

        5.06 Delivery of Policies, Payment of Premiums. Trustor shall furnish
Beneficiary with a certificate of insurance evidencing the insurance required
hereunder and naming Beneficiary as additional insured. If Trustor elects to
provide any of the required insurance through blanket policies carried by
Trustor and covering more than one location, then Trustor shall furnish
Beneficiary with a certificate of insurance for each such policy setting forth
the coverage, the limits of liability, the aggregate amount of all claims paid
under said policy, the nature of the carrier, the policy number, and the
expiration date. At least thirty (30) days prior to the expiration of each
required insurance policy (without regard to any grace period for nonpayment of
premium), Trustor shall furnish Beneficiary with evidence satisfactory to
Beneficiary of the payment of the premium and the reissuance of a policy
continuing in force without lapse or reduction in coverage.

        5.07 Insurance Proceeds. Trustor hereby agrees that after the happening
of any casualty to the Subject Property or any part thereof, Trustor shall give
prompt written notice thereof to Beneficiary.

        (a) Trustor hereby assigns its interest in all insurance proceeds to
        Beneficiary and authorizes and directs any affected insurance company to
        make payment of such proceeds directly to Beneficiary. Trustor shall
        obtain Beneficiary's approval, which approval shall not be unreasonably
        withheld or delayed, prior to any settlement, adjustment or compromise
        of any claims for loss, damage or destruction under any policy or
        policies of insurance, and Beneficiary shall have the right to
        participate with Trustor in negotiation of any such settlement,
        adjustment or compromise. Beneficiary shall also have the right to
        appear with Trustor in any action against an insurer based on a claim
        for loss, damage or destruction under any policy or policies of
        insurance.

                                      -5-
<PAGE>

        (b) All compensation, awards, proceeds, damages, claims, insurance
        recoveries, rights of action and payments which Trustor may receive or
        to which Trustor may become entitled with respect to the Subject
        Property or any part thereof (herein the "Proceeds") shall be paid over
        to the Beneficiary. In the event such loss or damage is less than Fifty
        Thousand Dollars ($50,000.00) the Proceeds will be paid to Trustor by
        Beneficiary and Trustor agrees to promptly thereafter repair and/or
        replace such damage or loss. In the event of a loss greater than Fifty
        Thousand Dollars ($50,000.00) ("Major Damage"), Beneficiary shall apply
        the Proceeds to the repair, replacement or restoration of the Subject
        Property in which event Beneficiary shall disburse the Proceeds in
        accordance with the procedures set forth in subparagraph (c) below. If
        there are any Proceeds in excess of the amount necessary to repay the
        Note and all other amounts secured hereby then such excess Proceeds
        shall be paid to Trustor.

        (c) Beneficiary shall disburse Proceeds to Trustor in connection with
        Major Damage, upon the satisfaction of the following conditions
        ("Disbursement Conditions"):

                (i) Proceeds have been deposited with the Beneficiary;

                (ii) Beneficiary shall have been furnished with a reasonable
                estimate of the cost of restoration accompanied by a certificate
                from a party acceptable to Beneficiary as to such costs and
                appropriate final plans and specifications for reconstruction of
                the improvements, if necessary, all of which shall be approved
                by Beneficiary;

                (iii) the improvements so restored or rebuilt shall be of
                substantially the same character and value as prior to the
                damage or destruction and appropriate for the purposes for which
                they were originally erected;

                (iv) Trustor shall have furnished Beneficiary with evidence
                satisfactory to Beneficiary that all improvements so restored
                and/or reconstructed and their use shall fully comply with all
                zoning, building and use laws, ordinances and regulations;

                (v) If the estimated cost of restoration exceeds the Proceeds
                available, Trustor shall have furnished a satisfactory bond of
                completion or deposited with Beneficiary such sums as may be
                necessary to pay such excess costs;

                (vi) Beneficiary shall have received notice within thirty (30)
                days after the fire or other hazard or of the condemnation
                proceedings specifying the date of such fire or other hazard or
                the date the notice of condemnation proceedings was received;

                (vii) Trustor shall not then be in default under the Note or
                this Deed of Trust,

then the Proceeds, less the actual costs, fees and expenses, if any, incurred in
connection with adjustment of loss and Beneficiary's administrative expenses
relating to the disbursement of the Proceeds shall be applied by Beneficiary to
the payment of all the costs of the aforesaid

                                      -6-
<PAGE>

restoration, repairs, replacement, rebuilding or alterations, (all of which are
hereinafter collectively referred to as the "Restoration"), and shall be paid
out by Beneficiary from time to time as such Restoration progresses upon the
written request of Trustor accompanied by the following:

                A certificate of an architect licensed in the State of
                California acceptable to Beneficiary, dated not more than thirty
                (30) days prior to such request, setting forth the following:

                        (A) That the sum then requested either has been paid, or
                        is justly due to contractors, subcontractors,
                        materialmen, engineers, architects or other persons who
                        have rendered services or furnished materials for the
                        restoration therein specified or have paid for the same,
                        the names and addresses of such persons, a brief
                        description of such services and materials, the several
                        amounts so paid or due to each of said persons in
                        respect thereof, that no part of such expenditures has
                        been or is being made on the basis of any previous or
                        then pending request for the withdrawal of Proceeds or
                        has been made out of any of the Proceeds received by
                        Trustor, and that the sum then requested does not exceed
                        the value of the services and materials described in the
                        certificate.

                        (B) That, except for the amount, if any, stated
                        (pursuant to the foregoing subclause (A)) in such
                        certificate to be due for services or materials, there
                        is no outstanding indebtedness known to the person
                        signing such certification, after due inquiry, which is
                        then due for labor, wages, materials, supplies or
                        services in connection with such restoration.

                        (C) That the costs, as estimated by the person signing
                        such certificate, of the Restoration required to be done
                        subsequent to the date of such certificate in order to
                        complete and pay for the same, do not exceed the
                        Proceeds, plus any amount or security approved by
                        Beneficiary and deposited by Trustor to defray such
                        costs and remaining in the hands of the Beneficiary
                        after payment of the sum requested in such certificate.

                Upon compliance with the foregoing provisions, Beneficiary
                shall, out of Proceeds (and the amount of security approved by
                Beneficiary, if any, deposited by Trustor to defray the costs of
                the Restoration), pay or cause to be paid to Trustor or the
                persons named (pursuant to Subclause (A) above) in such
                certificate the respective amounts (subject to subparagraph (e)
                below) stated therein to have been paid by Trustor or to be due
                to them, as the case may be.

        (d) If the Proceeds at the time held by the Beneficiary, less the actual
        costs, fees and expenses, if any, incurred in connection with the
        adjustment of the loss and the Beneficiary's administrative expenses
        relating to such loss and the disbursement of the Proceeds, shall be, in
        Beneficiary's reasonable judgment insufficient to pay the entire cost of
        the Restoration, Trustor shall deposit with the Beneficiary any such
        deficiency prior to disbursement of any additional portion of the
        Proceeds.

                                      -7-
<PAGE>

        (e) No payment made prior to the final completion of the Restoration
        shall exceed ninety percent (90%) of the value of the work performed
        from time to time, and at all times the undisbursed balance of said
        Proceeds remaining in the hands of the Beneficiary shall be at least
        sufficient to pay for the cost of completion of the Restoration free and
        clear of liens.

        (f) Final payment shall be upon an architect's certificate of completion
        in accordance with the final plans and specifications and compliance
        with all zoning, building, subdivision and other governmental laws,
        ordinances, rules, and regulations, and the filing of a Notice of
        Completion and the receipt of Beneficiary of final lien releases for
        such work or the expiration of the period provided under California law
        for the filing of mechanic's and materialmen's liens. Beneficiary may at
        its option require an Endorsement to its title insurance policy insuring
        the continued priority of the lien of this Deed of Trust as to all sums
        advanced hereunder. The cost of such endorsement will be paid by
        Trustor.

        (g) In the event of a "Condemnation" (as defined below), upon completion
        of the Restoration in a good and workmanlike manner in accordance
        herewith, and provided that Beneficiary has received satisfactory
        evidence that the Restoration has been paid for in full and the Subject
        Property is free and clear of all liens related to or in connection with
        the Restoration, any balance of the Proceeds at the time held by the
        Beneficiary (after reimbursement to Beneficiary of all costs and
        expenses of the Beneficiary, including administrative expenses, in
        connection with recovery of the same and disbursement of such Proceeds
        for the Restoration), if any, shall be applied as follows: (i) to the
        extent that such balance of the Proceeds is equal to or less than the
        amount, if any, by which the value of the Subject Property prior to such
        damage or destruction exceeds the value of the Subject Property after
        such Restoration (for these purposes, the value of the Subject Property
        shall be determined by Beneficiary in its discretion), then the portion
        of the balance of the Proceeds equal to such excess amount shall be
        applied to the payment or prepayment of the principal balance of the
        indebtedness outstanding under the Note in such order as Beneficiary may
        determine, and any amounts so applied shall reduce the indebtedness
        secured hereby pro tanto; and (ii) to the extent that the balance of the
        Proceeds exceeds such excess amount, such excess portion of the balance
        of the Proceeds shall, at Beneficiary's option, be applied so as to
        reduce the indebtedness secured hereby or be paid to Trustor.

        (h) Subject to Beneficiary releasing all available proceeds in
        accordance with the provisions of this Deed of Trust, nothing herein
        contained shall be deemed to excuse Trustor from repairing or
        maintaining the Subject Property as provided herein or restoring all
        damage or destruction to the Subject Property, regardless of whether or
        not there are insurance proceeds available or whether any such proceeds
        are sufficient in amount, and the application or release by the
        Beneficiary of any insurance proceeds shall not cure or waive any Event
        of Default, as hereinafter defined, or notice of default under this Deed
        of Trust or invalidate any other act done by Beneficiary to exercise its
        remedies hereunder.

        5.08 Condemnation. Should all or any part of the Subject Property or any
interest therein be taken or damaged by reason of any public improvement, by the
exercise of the power of eminent domain (whether by legal proceedings or
otherwise) by any person or entity having the legal power to do so, by a
voluntary sale or transfer either under threat of condemnation or while legal
proceedings for condemnation are pending, by inverse condemnation, or in any
other

                                      -8-
<PAGE>

similar manner (collectively a "Condemnation"), or should Trustor receive any
notice or other information regarding a Condemnation (whether threatened or
pending), Trustor shall give prompt written notice thereof to Beneficiary. In
the event of a Condemnation:

        (a) Beneficiary shall be entitled to, and is hereby assigned, all
        compensation, awards, damages, proceeds, or other payments or relief
        resulting therefrom (the "Condemnation Proceeds") to the extent of the
        principal balance of the indebtedness secured hereby together with any
        unpaid accrued interest thereon and other amounts due under the Note or
        this Deed of Trust. Beneficiary shall also be entitled at its option to
        appear in, and prosecute in its own name any Condemnation action or
        proceedings, and to make any reasonable compromise or settlement thereof
        taking into account Trustor's interest in the Subject Property. Trustor
        agrees to execute such further assignments of the Condemnation Proceeds
        as Beneficiary or Trustee may require. Whether or not Beneficiary
        appears in or prosecutes in its own name any such action or proceeding,
        Trustor shall be responsible for representing, at its sole cost, its own
        interest therein. Trustor hereby specifically, unconditionally, and
        irrevocably waives all rights of a property owner under the provisions
        of Section 1265.225(a) of the California Code of Civil Procedure or any
        successor statute, providing for the allocation of Condemnation Proceeds
        between a property owner and a lienholder.

        (b) Beneficiary shall have the option to apply all such Condemnation
        Proceeds, after deducting therefrom all costs and expenses incurred by
        it in connection with obtaining such Condemnation Proceeds, in the same
        manner and with the same effect provided for in paragraph 5.07 regarding
        the disposition of insurance proceeds. Such application or release shall
        not cure or waive any default or notice of default hereunder or
        invalidate any act done pursuant to such notice.

        5.09 Hazardous Materials Compliance, Notices, Inspections and
Indemnification. Trustor shall, and Trustor shall cause all tenants, employees,
agents, contractors and subcontractors of Trustor and any other persons present
on or occupying the Subject Property to, keep and maintain the Subject Property,
including the soil and ground water thereof, in compliance with, and not cause
or permit the Subject Property, including the soil and ground water thereof, to
be in violation of any federal, state or local laws, ordinances or regulations
relating to industrial hygiene or to the environmental conditions thereon
(including but not limited to any "Hazardous Materials Laws" as hereinafter
defined). Except in compliance with all applicable Hazardous Materials Laws,
neither Trustor nor employees, agents, contractors and subcontractors of Trustor
or any other persons occupying or present (including tenants) on the Subject
Property shall use, generate, manufacture, store or dispose of on, under or
about the Subject Property or transport to or from the Subject Property any
flammable explosives, radioactive materials, hazardous wastes, toxic substances
or related materials, including, without limitation, any substances defined as
or included in the definition of "hazardous substances," "hazardous wastes,"
"hazardous materials," or "toxic substances" under any Hazardous Materials Laws
(collectively referred to hereinafter as "Hazardous Materials"), except for
ordinary and customary materials used in the normal course of construction,
maintenance or use of the Property, so long a such materials are used and/or
stored in compliance with Hazardous Materials Laws.

                                      -9-
<PAGE>

        Trustor shall immediately advise Beneficiary in writing of: (i) any
notices (whether such notices are received from the Environmental Protection
Agency, the Occupational Safety and Health Agency, the Department of Health
Services, the State Water Quality Control Board, the Department of Sanitation,
the Department of Public Works or any other federal, state or local governmental
agency or regional office thereof) of violation or potential violation which are
received by Trustor of any applicable federal, state or local laws, ordinances,
or regulations relating to any Hazardous Materials including but not limited to
the Comprehensive Environmental Response, Compensation and Liability Act of
1980, as amended, the Hazardous Materials Transportation Act, the Resource
Conservation and Recovery Act, the Hazardous Substances Account Act, the
Hazardous Substances Act, the Occupational Health and Safety Act, the
Porter-Cologne Water Quality Control Act, the Solid Waste Management Act of
1980, the Toxic Pit Cleanup Act, the Underground Tank Act of 1984, and the
California Water Quality Improvement Act (collectively, "Hazardous Materials
Laws"); (ii) any and all enforcement, cleanup, removal or other governmental or
regulatory actions instituted, completed or threatened pursuant to any Hazardous
Materials Laws; (iii) all claims made or threatened in writing by any third
party against Trustor or the Subject Property relating to damage, contribution,
cost recovery compensation, loss or injury resulting from any Hazardous
Materials (the matters set forth in clauses (i), (ii) and (iii) above are
hereinafter referred to as "Hazardous Materials Claims"); and (iv) Trustor's
discovery of any occurrence or condition on any real property adjoining or in
the vicinity of the Subject Property that could cause the Subject Property or
any part thereof to be classified as "border-zone property" under the provisions
of California Health and Safety Code, Sections 25220 et seq. or any regulation
adopted in accordance therewith, or to be otherwise subject to any restrictions
on the ownership, occupancy, transferability or use of the Subject Property
under any Hazardous Materials Laws.

        Trustor shall be solely responsible for, and shall indemnify and hold
harmless Beneficiary, its directors, officers, employees, agents, successors and
assigns from and against, any loss, damage, cost, expense or liability directly
or indirectly arising out of or attributable to the use, generation, storage,
release, threatened release, discharge, disposal, or presence (whether prior to
or during the term of the loan secured by this Deed Trust) of Hazardous
Materials on, under or about the Property (whether by Borrower or a predecessor
in title or any employees, agents, contractors or subcontractors of Borrower or
any predecessor in title or any third persons at any time occupying or present,
including tenants, on the Subject Property), including, without limitation: (a)
all foreseeable and unforeseeable consequential damage, including third party
claims; (b) the costs of any required or necessary repair, cleanup or
detoxification of the Subject Property, including the soil and ground water
thereof, and the preparation and implementation of any closure, remedial or
other required plans; (c) damages to any natural resources; and (d) all
reasonable costs and expenses incurred by Beneficiary in connection with clauses
(a), (b) and (c), including but not limited to reasonable attorneys' and
consultants' fees.

        Any costs or expenses incurred by Beneficiary for which Trustor is
responsible or for which Trustor has indemnified Beneficiary shall be paid to
Beneficiary on demand, and failing prompt reimbursement, shall be added to the
indebtedness secured by this Deed of Trust and earn interest at the Default Rate
set forth in the Note until paid in full.

                                      -10-
<PAGE>

        Trustor shall take any and all remedial action necessary in response to
the presence of any Hazardous Materials on, under, or about the Subject
Property, provided that in such event Trustor shall notify Beneficiary as soon
as practicable of any action so taken.

        If Beneficiary has reasonable cause (based on written notice) to believe
that a release, or the threat of a release, of any Hazardous Materials exists or
if an Event of Default has occurred and remains uncured, then upon Beneficiary's
request, Trustor shall retain, at Trustor's sole cost and expense, a licensed
geologist, industrial hygienist or an environmental consultant (referred to
hereinafter as the "Consultant") acceptable to Beneficiary to conduct a baseline
investigation of the Property for the presence of Hazardous Materials
("Environmental Audit"). The Environmental Audit shall be performed in a manner
reasonably calculated to discover the presence of Hazardous Materials
contamination; provided, however, such investigation shall be of a scope and
intensity no greater than a baseline investigation conducted in accordance with
the general standards of persons providing such services taking into
consideration the known uses of the Subject Property and property in the
vicinity of the Subject Property and any factors unique to the Subject Property.
The Consultant shall concurrently deliver the results of its investigation in
writing directly to Trustor and Beneficiary without prior consultation with
either party unless conducted in the presence of the other party. Such results
shall be kept confidential by both Trustor and Beneficiary unless legally
compelled or required to disclose such results or disclosure is reasonably
required in order to pursue rights or remedies provided herein or at law.

        If Trustor fails to pay for or obtain an Environmental Audit as provided
for herein, Beneficiary may, but shall not be obligated to, obtain the
Environmental Audit, and either demand reimbursement from Trustor or add the
cost thereof to the indebtedness secured by this Deed of Trust, in which case
interest shall accrue on such sum at the Default Rate from the date of demand.

        Trustor covenants to reasonably cooperate with the Consultant and to
allow entry and reasonable access to all portions of the Subject Property for
the purpose of Consultant's investigation. Trustor covenants to comply, at its
sole cost and expense, with all recommendations contained in the Environmental
Audit, including any recommendation for additional testing and studies to detect
the presence of Hazardous Materials, if Beneficiary requires the implementation
of the same.

        5.10 Liens and Encumbrances. Trustor shall pay or cause to be paid at or
prior to maturity, all obligations secured by or reducible to liens and
encumbrances which shall now or hereafter encumber or appear to encumber the
Subject Property or any part thereof, all claims for work or labor performed, or
materials or supplies furnished, in connection with any work of demolition,
alteration, improvement of or construction upon the Subject Property.
Beneficiary hereby expressly reserves the right to advance any and all funds
necessary to cure any and all such obligations and/or claims after providing
written notice to Trustor and a five (5) day opportunity to cure.

        5.11 Maintenance and Preservation of the Subject Property. Trustor
covenants (i) to keep the Subject Property in good condition and repair; (ii)
not to remove or demolish the Subject Property or any part thereof; (iii) to
complete or restore promptly and in good and workmanlike manner the Subject
Property or any part thereof which may be damaged or

                                      -11-
<PAGE>

destroyed; (iv) to comply with and not suffer violations of (a) all laws,
ordinances, regulations, standards, and (b) all covenants, conditions,
restrictions and equitable servitudes, whether public or private, of every kind
and character, and (c) all requirements of insurance companies and any bureau or
agency which establishes standards of insurability, which laws, covenants or
requirements affect the Subject Property and pertain to acts committed or
conditions existing thereon, including, but without limitation, such work or
alteration, improvement or demolition as such laws, covenants or requirements
mandate; (v) not to commit or permit waste thereof; (vi) to do all other acts
which from the character or use of the Subject Property may be reasonably
necessary to maintain it in the condition (reasonable wear and tear excepted) as
of the date of this Deed of Trust; (vii) to perform all obligations required to
be performed by Trustor pertaining to the Subject Property, including, but not
limited to, any and all leases or subleases of which Trustor is or shall be the
lessor or sublessor (and in the event of default, all right, title and interest
of Trustor under any such leases or subleases and any and all other agreements
affecting the Subject Property in which Trustor shall have an interest shall be
and hereby are automatically assigned to Beneficiary hereunder, together with
any deposits made in connection therewith); (viii) not to create any deed of
trust or encumbrance upon the Subject Property subsequent hereto; and (ix) to
execute, and where appropriate acknowledge, and deliver such further instruments
as Beneficiary or Trustee deems necessary or appropriate to preserve, continue,
perfect and enjoy the security provided for herein, including, but without
limitation, assignments of Trustor's interest in leases or subleases of the
Subject Property.

        5.12 Defense and Notice of Actions. Trustor shall, without liability,
cost or expense to Beneficiary or Trustee, protect, preserve and defend
Trustor's fee interest in and to the Subject Property, the security hereof or
the rights or powers of Beneficiary or Trustee hereunder. Said protection,
preservation and defense shall include protection, preservation and defense
against all adverse claimants to Trustor's interest in the Subject Property
whether or not such claimants or encumbrances assert title paramount to that of
Trustor or claim their interest on the basis of events or conditions arising
subsequent to the date hereof. Trustor shall give Beneficiary and Trustee prompt
notice in writing of the filing of any such action or proceeding.

        5.13 Collection of Rents, Issues and Profits. Beneficiary confers upon
Trustor a license to collect and retain the rents, issues and profits of the
Subject Property as they become due and payable, subject, however, to the right
of Beneficiary upon default hereunder to revoke said authority at any time in
its sole discretion and without notice to Trustor. Beneficiary may revoke said
authority and collect and retain the rents, issues and profits of the Subject
Property assigned herein to Beneficiary upon the occurrence of an Event of
Default hereunder or under any of the obligations secured hereby, and without
taking possession of all or any part of the Subject Property, and without
prejudice to or limitation upon any of its additional rights and remedies
granted pursuant hereto or pursuant to the Note or this Deed of Trust.

        5.14 Right of Inspection. Subject to the rights of tenants under their
respective leases, Beneficiary, its agents or employees, may enter the Subject
Property at any reasonable time for the purpose of inspecting the Subject
Property and ascertaining Trustor's compliance with the terms hereof.

        5.15 Acceptance of Trust, Notice of Indemnification. Trustee accepts
this trust when this Deed of Trust, duly executed and acknowledged, becomes a
public record as provided by

                                      -12-
<PAGE>

law. Trustee is not obligated to notify any party hereto of pending sale under
any other deed of trust or of any action or proceeding in which Trustor,
Beneficiary or Trustee shall be a party unless Trustee brings such action.
Trustee shall not be obligated to perform any act required of it hereunder
unless the performance of such act is requested in writing and Trustee is
reasonably indemnified against loss, cost, liability and expense.

        5.16 Powers of Trustee. From time to time upon written request of
Beneficiary and presentation of this Deed of Trust for endorsement, and without
affecting the personal liability of any person for payment of any indebtedness
or performance of the obligation secured hereby, Trustee may, without liability
therefor and without notice (i) reconvey all or any part of the Subject
Property; (ii) consent to the making of any map or plat thereof; (iii) join in
granting any easement thereon; (iv) join in any declaration of covenants and
restrictions; or (v) join in any extension agreement or any agreement
subordinating the lien or charge hereof. Trustee or Beneficiary may from time to
time apply to any court of competent jurisdiction for aid and direction in the
execution of the trusts hereunder and the enforcement of the rights and remedies
available hereunder, and Trustee or Beneficiary may obtain orders or decrees
directing or confirming or approving acts in the execution of said trusts and
the enforcement of said remedies. Trustee has no obligation to notify any party
of any pending sale or any action or proceeding unless held or commenced and
maintained by Trustee under this Deed of Trust. Trustor shall pay to Trustee
reasonable compensation and reimbursement for services and expenses in the
administration of the trusts created hereunder, including reasonable attorneys'
fees. Trustor hereby agrees to indemnify Trustee and Beneficiary against all
losses, claims, demands and liability which either may incur, suffer or sustain
in the execution of the trust or trusts created hereunder or in the performance
of any act required or permitted hereunder or by law.

        5.17 Substitution of Trustees. From time to time, by a writing signed
and acknowledged by Beneficiary and recorded in the Office of the Recorder of
the County in which the Subject Property is situated, Beneficiary may appoint
another trustee to act in the place and stead of Trustee or any successor. Such
writing shall refer to this Deed of Trust and set forth the date, book and page
of its recordation. The recordation of such instrument of substitution shall
discharge Trustee herein named and shall appoint the new trustee as the trustee
hereunder with the same effect as if originally named Trustee herein. A writing
recorded pursuant to the provisions of this paragraph shall be conclusive proof
of the proper substitution of such new trustee.

        5.18 Acceleration Upon Sale or Encumbrance. That the financial stability
and managerial and operational ability of Trustor are a substantial and material
consideration to Beneficiary in its agreement to enter into the transaction
evidenced by this Deed of Trust and the Note is hereby acknowledged by Trustor
and Beneficiary. That the transfer or further encumbrance of the Subject
Property, could significantly and materially alter, impair and reduce
Beneficiary's security for the Note is likewise acknowledged by Trustor and
Beneficiary. In order, therefore, to induce Beneficiary to accept the Note,
except with respect to a transfer which is included in items (i) and (ii) of the
definition of "Authorized Transfer," in Section 3.7 of the Participation
Agreement (a "Permitted Transfer"), Trustor agrees not to transfer or further
encumber the Subject Property, or any portion thereof, or any interest therein,
without the prior written consent of Beneficiary. In the event Trustor, or any
successor in interest of Trustor, shall

                                      -13-
<PAGE>

transfer or further encumber the Subject Property or any portion thereof, or any
interest therein, other than by a Permitted Transfer, without first obtaining
the written consent of Beneficiary, all indebtedness secured by this Deed of
Trust, including without limitation the unpaid principal balance due on the
Note, irrespective of the maturity date of the Note, shall, at the option of
Beneficiary and without notice or demand, become immediately due and payable. As
used herein, "transfer" includes the sale, option to sell, transfer or
conveyance of the Subject Property, or any portion thereof, or any interest
therein, or the transfer of any general partnership interests, membership
interests or shares of stock (as applicable) in Trustor, whether voluntary,
involuntary (except by eminent domain or upon death or mental incapacity), by
operation of law or otherwise, except that the transfer of outstanding capital
stock or other listed equity interests by persons or parties through the
"over-the-counter" market or any recognized national or international securities
exchange, shall not be included in determining whether Subject Property has been
transferred.

        5.19 Intentionally Left Blank.

        5.20 Reconveyance. Upon Beneficiary's written request, and upon
surrender to Trustee for cancellation of this Deed of Trust and any note,
instrument or instruments setting forth all obligations secured hereby, Trustee
shall reconvey, without warranty, the Subject Property or that portion thereof
then held hereunder. The recitals of any matters or facts in any reconveyance
executed hereunder shall be conclusive proof of the truthfulness thereof. To the
extent permitted by law, the reconveyance may describe the grantee as "the
person or persons legally entitled thereto." Neither Beneficiary nor Trustee
shall have any duty to determine the right of persons claiming to be rightful
grantees of any reconveyance. When the Subject Property has been fully
reconveyed, the last such reconveyance shall operate as a reassignment of all
future rents, issues and profits of the Subject Property to the person or
persons legally entitled thereto, unless such reconveyance expressly provides to
the contrary.

                                       VI.

                               DEFAULT PROVISIONS

        The following shall constitute events of default ("Events of Default")
hereunder:

        6.01 Payment. Failure of Trustor to make any payment required under this
Deed of Trust or the Note when and as it becomes due and payable.

        6.02 Breach of General Covenants. A default by Trustor in the due,

obligation, covenant and agreement in the Note or in this Deed of Trust, other
than a default specified in paragraph 6.01 above and the continuation of the
default for a period of thirty (30) days after Trustor's receipt of written
notice by Beneficiary describing the defect in reasonable detail and demanding
its cure, however, if the default is of a type which, for reasons other than
reasons within the reasonable control of Trustor, is not susceptible of cure
within such thirty (30) day period, but is susceptible of cure within a
reasonable period of time, then no Event of Default shall occur under this
paragraph unless Trustor shall fail to commence to cure such default within
thirty (30) day

                                      -14-
<PAGE>

period or shall fail to diligently pursue the cure of such default to completion
within a reasonable period of time thereafter.

        6.03 Intentionally Omitted.

        6.04 Appointment of Receiver. The appointment, pursuant to an order of a
court of competent jurisdiction, of a trustee, receiver or liquidator of the
Subject Property or any part thereof, or of Trustor, unless such appointment is
discharged within ninety (90) days after the date of filing thereof.

        6.05 Bankruptcy Filing By Trustor. The filing by Trustor of a petition
in bankruptcy or for an arrangement or for reorganization pursuant to the
Federal Bankruptcy Code or any similar law, federal or state, or the
adjudication of Trustor as a bankrupt or as insolvent by a decree of a court of
competent jurisdiction, or the making of an assignment for the benefit of
creditors, or the admission by Trustor in writing of its inability to pay its
debts generally as they become due, or the giving of consent by Trustor to the
appointment of a receiver or receivers of all or any part of its property,
unless such bankruptcy filing is discharged within ninety (90) days after the
date of filing thereof.

        6.06 Bankruptcy Filing by Creditors. The filing by any of the creditors
of Trustor or the reorganization of Trustor pursuant to the Federal Bankruptcy
Code or any similar law, federal or state and the same is not discharged within
ninety (90) days after the date of filing thereof.

        6.07 Intentionally Omitted.

        6.08 Intentionally Omitted.

        6.09 Rights and Remedies. At any time after the occurrence of an Event
of Default hereunder, Beneficiary and/or Trustee shall have the following rights
and remedies, all of which are in addition to any rights and remedies available
to Beneficiary under the Note or this Deed of Trust:

        (a)    With or without notice, to declare all obligations secured hereby
        immediately due and payable;

        (b) With or without notice, and without releasing Trustor from any
        obligation hereunder, to cure any default of Trustor and, in connection
        therewith, to enter upon the Subject Property and to do such acts and
        things as Beneficiary or Trustee deem necessary or desirable to protect
        the security hereof, including, but without limitation, to appear in and
        defend any action or proceeding purporting to affect the security hereof
        or the rights or powers of Beneficiary or Trustee hereunder; to pay,
        purchase, contest or compromise any encumbrance, charge, lien or claim
        of lien which, in the judgment of either Beneficiary or Trustee is prior
        or superior hereto, the judgment of Beneficiary or Trustee being
        conclusive as between the parties hereto; to pay any premiums or charges
        with respect to insurance required to be carried hereunder; and to
        employ counsel, accountants, contractors and other appropriate persons
        to assist them;

                                      -15-
<PAGE>

        (c) To commence and maintain an action or actions in any court of
        competent jurisdiction to foreclose this instrument as a mortgage or to
        obtain specific enforcement of the covenants of Trustor hereunder, and
        Trustor agrees that such covenants shall be specifically enforceable by
        injunction or any other appropriate equitable remedy and that for the
        purposes of any suit brought under this subparagraph, Trustor waives the
        defense of laches and any applicable statute of limitations;

        (d) To enter upon, possess, manage and operate the Subject Property or
        any part thereof; to make, terminate, enforce or modify leases of the
        Subject Property upon such terms and conditions as Beneficiary deems
        proper; to make repairs, alterations and improvements to the Subject
        Property necessary, in Trustee's or Beneficiary's judgment, to protect
        or enhance the security hereof. All sums realized by Beneficiary under
        this subparagraph, less all costs and expenses incurred by it under this
        subparagraph, including reasonable attorneys' fees, and less such sums
        as Beneficiary deems appropriate as a reserve to meet future expenses
        under this subparagraph, shall be applied on any indebtedness secured
        hereby in such order as Beneficiary shall determine. Neither application
        of said sums to said indebtedness nor any other action taken by
        Beneficiary under this subparagraph shall cure or waive any default or
        notice of default hereunder or nullify the effect of any such notice of
        default. Beneficiary or Trustee, or any employee or agents of
        Beneficiary or Trustee, or a receiver appointed by a court may take any
        action or proceeding authorized hereunder or by law without regard to
        (i) the adequacy of the security for the indebtedness secured hereunder,
        (ii) the existence of a declaration that the indebtedness secured hereby
        has been declared immediately due and payable, or (iii) the filing of a
        notice of default;

        (e) To execute a written notice of such default and of its election to
        cause the Subject Property to be sold to satisfy the obligations secured
        hereby. Trustee shall give and record such notice as the law then
        requires as a condition precedent to a Trustee's sale. When the minimum
        period of time required by law after such notice has elapsed, Trustee,
        without notice to or demand upon Trustor except as otherwise required by
        law, shall sell the Subject Property at the time and place of sale fixed
        by it in the notice of sale, either as a whole or in separate parcels
        and in such order as it or Beneficiary may determine, at public auction
        to the highest bidder for cash, in lawful money of the United States,
        payable at time of sale (the obligations hereby secured being the
        equivalent of cash for purposes of said sale). Trustor shall have no
        right to direct the order in which the Subject Property is sold. Trustee
        may if so instructed by Beneficiary postpone sale of all or any portion
        of the Subject Property by public announcement at such time and place of
        sale, and from time to time thereafter may postpone such sale by public
        announcement at such time fixed by the preceding postponement. Trustee
        shall deliver to the purchaser at such sale a deed conveying the Subject
        Property or portion thereof so sold, but without any covenant or
        warranty, express or implied. The recitals in such deed of any matters
        or facts shall be conclusive proof of the truthfulness thereof. Trustor
        or Beneficiary, but not Trustee, may purchase at such sale.

        After deducting all costs, fees and expenses of Trustee and of this
        trust, including cost of evidence of title and reasonable attorneys'
        fees in connection with the sale, Trustee shall apply the proceeds of
        sale to payment of (i) all sums so expended under the terms hereof not
        then repaid, with accrued interest at the Default Rate; (ii) the payment
        of all other sums then secured hereby in such order as Beneficiary may
        direct; and (iii) the remainder, if any, to the person or persons

                                      -16-
<PAGE>

        legally entitled thereto;

        (f) To resort to and realize upon or waive the security hereunder and
        any other security now or hereafter held by Beneficiary in such order
        and manner as Trustee and Beneficiary or either of them may, in their
        sole discretion determine; resort to any or all such security may be
        taken concurrently or successively and in one or several consolidated or
        independent judicial actions or lawfully taken non-judicial proceedings,
        or both;

        (g) With respect to all or any part of the encumbered Property that
        constitutes personalty, Beneficiary shall also have all of the rights

                     PARTICIPATION AND PUT OPTION AGREEMENT

      This PARTICIPATION AND PUT OPTION AGREEMENT ("AGREEMENT") is made and
entered into as of September 5, 2002, by and among PARKSIDE TOWERS CO-TENANCY, a
tenancy in common between GATEWAY PHOENIX ASSOCIATES, L.P., a California limited
partnership, and 5990 SEPULVEDA ASSOCIATES, L.P., a California limited
partnership (collectively, "PARKSIDE"), EOP Operating Limited Partnership, a
Delaware limited partnership ("EQUITY OFFICE"), and INKTOMI CORPORATION, a
Delaware corporation ("INKTOMI").

                                R E C I T A L S :

      A.    Concurrently herewith, Parkside, Equity Office and Inktomi have
entered into that certain Lease Termination Agreement ("LEASE TERMINATION
AGREEMENT"), pursuant to which Parkside has agreed to terminate the "Lease," as
defined in the Lease Termination Agreement, in exchange for certain
consideration from Inktomi to Parkside and/or Equity Office, including (i)
Inktomi's agreement to enter into this Agreement, and (ii) Inktomi's making of
the Note in the initial principal amount of $21,500,000.00, which Note is
secured by the "Note Deed of Trust" encumbering Inktomi's interest in the
"Bayside Project", as those terms also are defined in the Lease Termination
Agreement.

      B.    Inktomi desires to hereby grant Equity Office the right to
participate in the value, if any, of the Bayside Project in excess of an agreed
minimum amount (the "PARTICIPATION INTEREST") on the terms and conditions set
forth herein. Equity Office directly or indirectly owns and controls Parkside.

      C.    Equity Office desires to hereby grant Inktomi an option to sell the
Bayside Project to Equity Office (the "PUT OPTION") on the terms and conditions
set forth herein.

      D.    Parkside executes this Agreement to acknowledge that it
constitutes the Participation Agreement contemplated by the Lease Termination
Agreement.  However, this Agreement confers no rights or obligations on
Parkside.

                               A G R E E M E N T :

      NOW, THEREFORE, in consideration of the foregoing recitals and the mutual
covenants contained herein, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
hereby agree as follows.

1.    GENERAL TERMS. All undefined terms when used herein shall have the same
respective meanings as are given such terms in the Lease Termination Agreement,
unless expressly provided otherwise in this Agreement. The terms of this
Agreement shall be immediately binding upon the full execution and delivery of
this Agreement, but this Agreement shall become effective only upon the "Lease
Termination Date," as defined in the Lease Termination Agreement. To the extent
required hereunder, Equity Office shall take any and all actions required to
cause Parkside to act in accordance with any obligations of Equity Office
hereunder.

<PAGE>
2.    GRANT OF PARTICIPATION INTEREST.

      2.1   GRANT. Inktomi hereby grants to Equity Office the Participation
Interest, consisting of the right to receive fifty percent (50%) of the amount,
if any, by which the "Value", as defined in Section 3.3 below, of the Bayside
Project exceeds $50,000,000.00 (the "BASE VALUE"). This Participation Interest
consists of only a contractual right to receive a stipulated sum of money in the
event the Value exceeds the Base Value, and does not constitute an interest in,
or confer any lien upon or create any other encumbrance against, the Bayside
Project, except through the operation of the "Participation Deed of Trust",
defined in Section 2.2, below. Any payment to be made by Inktomi to Equity
Office in satisfaction of the Participation Interest is referred to in this
Agreement as the "PARTICIPATION PAYMENT."

      2.2   DEED OF TRUST AS SECURITY. To secure Inktomi's obligation to
recognize the Participation Interest, concurrently with the execution of this
Agreement, Inktomi has executed, acknowledged and delivered the Participation
Deed of Trust in the form attached as Exhibit A to this Agreement (the
"PARTICIPATION DEED OF TRUST"), which will on the Lease Termination Date
encumber Inktomi's fee title in the Bayside Project. The Participation Deed of
Trust is subordinate and junior to the Note Deed of Trust.

3.    RECOGNITION OR TERMINATION OF PARTICIPATION INTEREST.

      3.1   LIQUIDITY EVENT.

            3.1.1 MARKETING BAYSIDE PROJECT. Equity Office acknowledges that
Inktomi has retained Eastdil Realty Co., Inc. ("Eastdil") to arrange a
recapitalization of the Bayside Project, to be accomplished through a bona fide
sale (including a sale at a "foreclosure") of the Bayside Project (the
"LIQUIDITY EVENT") to an unaffiliated third party (the "LIQUIDITY PURCHASER").
In connection with this Liquidity Event, it is anticipated that Inktomi will
enter into a lease-back arrangement (the "LEASE-BACK") with the Liquidity
Purchaser on approximately the same economic terms (consisting of the lease
term, base rent, pass through of operating expenses and taxes, amount of letter
of credit security, rights to renew and renewal rent) as are contained in the
"Lease-Back Lease," as defined in Section 4.2.2 below, and demising only that
portion of the Bayside Project as is described in the Lease-Back Lease. Inktomi
shall use commercially reasonable efforts and customary due diligence to arrange
a Liquidity Event in accordance with this Agreement on or before the
"Participation Date," as defined in Section 3.2 below, but Inktomi may arrange a
Liquidity Event on terms other than those in the Lease-Back Lease and with a
Liquidity Purchaser which is not an unaffiliated third party.

            3.1.2 RIGHT TO SELL. Inktomi shall be free to enter into and
consummate a Liquidity Event without prior notice to, or the approval of Equity
Office. However, where the Liquidity Event has not been approved by Equity
Office prior to the consummation thereof (either because Equity Office does not
have notice of the Liquidity Event or because Equity Office withholds its
approval pursuant to Section 3.1.3, below), Equity Office shall be obligated to
reconvey the Participation Deed of Trust only upon the payment of the "Release
Amount," as defined in Section 3.4.1, below, into "Escrow", as that term is
defined in Section 3.4.2, below, and such reconveyance shall not extinguish the
rights of Equity Office to receive the full amount

                                      -2-
<PAGE>

of the Participation Payment, including any such amounts which are in excess of
the Release Amount.

            3.1.3 RIGHT TO REVIEW SALE TERMS. Within five (5) business days
after reaching agreement on the terms and conditions of a Liquidity Event (but
not necessarily before the consummation thereof), Inktomi shall present such
terms and conditions to Equity Office, together with copies of all of the fully
executed documents evidencing the proposed Liquidity Event and any other
information reasonably required by Equity Office to enable Equity Office to
determine the relationship or lack of relationship between Inktomi and the
Proposed Purchaser. Equity Office shall give or withhold such approval, in its
sole discretion, within five (5) business days after request therefor. The
failure of Equity Office to respond as required by this section within such five
(5) business day period shall be deemed an approval by Equity Office. If Equity
Office approves or is deemed to approve such Liquidity Event, Equity Office
shall be deemed to have approved the amount of the Participation Payment
reflected in the documents provided by Inktomi in connection with its request
for approval. If Equity Office disapproves the Liquidity Event, its notice of
disapproval must include Equity Office's good faith estimate of the "Appraised
Value," as defined in Section 3.3.2, of the Bayside Project, and the
corresponding Participation Payment.

            3.1.4 RESTRICTION ON TRANSFERS. Other than in connection with (i) an
"Authorized Transfer" as defined in Section 3.7 of this Agreement, (ii) a
Liquidity Event under Section 3.3.1 of this Agreement, or (iii) the exercise of
the Put Option under Section 4 of this Agreement, Inktomi shall not sell,
assign, mortgage, pledge, hypothecate, encumber, master lease or ground lease,
or permit any lien to attach to or be executed upon, or otherwise voluntarily
transfer, any interest whatsoever in the Bayside Property.

            3.1.5 SOLE REMEDY. Except as expressly set forth in the
Participation Deed of Trust, Equity Office's sole remedy for breach of Inktomi's
covenants under Sections 3.1.1 and 3.1.4, above, shall be to advance the
Liquidity Event Deadline in accordance with Section 3.5.1, below, and cause the
"Appraisal Determination", as defined in Section 3.6.3, below, to be made as of
the date prior to such breach, as if such breach had not occurred.

      3.2   PARTICIPATION DATE. The Participation Interest, if any, granted to
Equity Office shall be (i) if the Participation Payment has been approved by
Equity Office and Inktomi, paid to Equity Office on, or (ii) if the
Participation Payment has not been approved by Equity Office and Inktomi, valued
as of, the "PARTICIPATION DATE," which date shall be the earlier of (i) the
closing date of a Liquidity Event (the "LIQUIDITY CLOSING") or (ii) January 21,
2003, as that date may be advanced or extended in accordance with Section 3.5.1
below (the "LIQUIDITY EVENT DEADLINE"). The Value of the Bayside Project shall
be calculated as of the Participation Date using the "Liquidity Value," as
defined in Section 3.3.1, or the Appraised Value, whichever is applicable. If
the Value as so determined is equal to or less than the Base Value, the
Participation Interest shall terminate and be of no further force or effect; and
if the Value as so determined is greater than the Base Value, Inktomi shall pay
the Participation Payment in accordance with this Agreement.

                                      -3-
<PAGE>

      3.3   VALUATION. The "VALUE" of the Bayside Project, for purposes of
recognizing or terminating the Participation Interest, shall be either the
Liquidity Value, as determined under Section 3.3.1 below, or the Appraised
Value, as determined under Section 3.3.2 below.

            3.3.1 LIQUIDITY VALUE. The term "LIQUIDITY VALUE" shall mean the
total net proceeds of a Liquidity Event paid to Inktomi, including, without
limitation, cash, assumed indebtedness, notes or other deferred payments,
prepaid expenses and non-customary prorations which materially benefit Inktomi
(provided, however, that the Value shall reflect the fair market value of all
non-cash consideration received in connection with such Liquidity Event, whether
or not contingent, with appropriate discounting to reflect the net present value
of any notes or deferred payments or the likelihood of any contingency being
satisfied or the debt being collected), as adjusted by the "Lease-Back
Adjustment." The "LEASE-BACK ADJUSTMENT" shall mean an increase or decrease in
the Liquidity Value which shall equal the positive or negative difference
between (i) the net present value of the Base Rent rental stream (i.e., $1.50
per rentable square foot of the Inktomi Premises per month) for the first five
(5) years of the Lease-Back Lease, discounted at an annual discount rate of 11%
(the "ASSUMED LEASE VALUE"), and (ii) the net present value of the Base Rent
rental stream (which rental stream shall be calculated on an effective basis by
deducting on a straight-line basis any monetary concessions received by Inktomi
over the term of the Lease-Back Lease) for the first five (5) years of the
Lease-Back actually agreed to in connection with the Liquidity Event, also
discounted at an annual discount rate of 11% (the "ACTUAL LEASE VALUE"). If such
difference is positive (i.e., if the Actual Lease Value is greater than the
Assumed Lease Value), then the Liquidity Value shall be decreased by the amount
of such difference. If such difference is negative (i.e., if the Actual Lease
Value is less than the Assumed Lease Value), then the Liquidity Value shall be
increased by the amount of such difference.

            3.3.2 APPRAISED VALUE. The "APPRAISED VALUE" shall mean the Value of
the Bayside Project established by the "Arbitration Determination, as defined in
Section 3.6.3 below.

            3.3.3 VALUE NET OF TRANSACTION COSTS. Regardless of whether the
Value of the Bayside Project is based on the Liquidity Value or the Appraised
Value, the Value shall be net of all reasonable and customary costs to be paid
or incurred in connection with the Liquidity Event (or which a seller could
reasonably be expected to pay or incur, where Value is being determined without
the prior occurrence of a Liquidity Event), including, without limitation,
escrow and recording fees, transfer taxes, title insurance premiums and
reasonable fees for brokerage commissions, attorneys, appraisers, surveyors,
engineers and other experts (including any consideration paid to Eastdil) and
prorations ordinarily deducted from the sales price.

      3.4   CONSUMMATION OF LIQUIDITY EVENT. Concurrently with the Liquidity
Closing, Inktomi shall repay the Note in full, together with any accrued and
outstanding interest owing thereon, and Inktomi also shall pay either (i) if
Equity Office has approved the Liquidity Event and the Liquidity Closing occurs
on or before the Liquidity Event Deadline, the amount of the Participation
Payment, if any, calculated using the Liquidity Value (in which case the
Participation Payment shall be paid to Equity Office at the Liquidity Closing),
(ii) if the Liquidity Closing occurs following Equity Office's approval of the
Liquidity Event, but after the Liquidity Event Deadline (as extended under
Section 3.5.1, below) associated with such Liquidity event, the Release Amount
(in which case the Release Amount shall be paid as provided in Section 3.4.2
below), or (iii) if the Liquidity Closing occurs without Equity Office's
approval (regardless of the timing of such event), the Release Amount (in which
case the Release Amount shall be paid as

                                      -4-
<PAGE>

provided in Section 3.4.2 below). Conditioned upon such payment(s), Equity
Office shall concurrently reconvey and release or otherwise extinguish the Note
Deed of Trust, the Participation Deed of Trust, and any other liens or
encumbrances against the Bayside Property relating thereto or to the
Participation Interest created by this Agreement.

            3.4.1 RELEASE AMOUNT CALCULATION. The "RELEASE AMOUNT," shall be the
lesser of (i) the Participation Payment specified in Equity Office's notice of
disapproval delivered under Section 3.1.3 above, or, if Equity Office has
previously approved a Liquidity Event, but the Liquidity Closing occurs after
the Liquidity Event Deadline, then the Estimate designated by Equity Office
under Section 3.6.2, below, or (ii) Two Million Five Hundred Thousand Dollars
($2,500,000.00).

            3.4.2 PAYMENT OF RELEASE AMOUNT. If the Release Amount is calculated
under clause (i) of Section 3.4.1, above, and Inktomi elects to accept such
amount as the Participation Payment, the Release Amount shall be paid to Equity
Office in connection with the Liquidity Closing and such payment shall fully
satisfy and forever release and discharge the Participation Interest. If the
Release Amount is calculated under clause (i) of Section 3.4.1 above and Inktomi
does not accept such amount as the Participation Payment, or if Release Amount
is calculated under clause (ii) of Section 3.4.1 above, the Release Amount shall
be paid into the same escrow account through which the Liquidity Closing is
conducted (the "ESCROW") under mutual, irrevocable instructions from Equity
Office and Inktomi directing that the Release Amount be paid to Equity Office,
or returned to Inktomi, or partially paid and partially returned to each such
party, out of the Escrow based on the Participation Payment established by the
Arbitration Determination. Notwithstanding the foregoing, the payment of the
Release Amount into Escrow, and any subsequent release of such Release Amount to
Equity Office, shall not release Inktomi from its obligation to pay any
additional amounts if the Participation Payment due to Equity Office based on
the Arbitration Determination exceeds the Release Amount. Concurrently with its
deposit of the Release Amount into the Escrow, Inktomi shall notify Equity
Office in writing of Inktomi's estimate of the Appraised Value of the Bayside
Project and the corresponding amount of the Participation Payment.

      3.5   FAILURE TO OBTAIN LIQUIDITY EVENT.

            3.5.1 CHANGE IN LIQUIDITY EVENT DEADLINE. Equity Office may advance
the Liquidity Event Deadline if Inktomi breaches the covenants in Sections 3.1.1
or 3.1.4, above, in which event (i) the Participation Date for determining the
Appraised Value shall be the date immediately preceding Inktomi's breach of such
covenant, and (ii) the Appraisal Determination shall be made as if such breach
had not occurred. If requested by Inktomi, Equity Office will not unreasonably
withhold its consent to extending the Liquidity Event Deadline for up to 30 days
after January 21, 2003, if on the date Inktomi requests such extension there is
a pending Liquidity Event approved by Equity Office (as provided in Section
3.1.3 above) and the parties thereto reasonably and in good faith expect (and so
notify Equity Office in writing) that all closing conditions for such Liquidity
Event will be satisfied within the period covered by the requested extension of
the Liquidity Event Deadline. In all other instances, Equity Office may grant or
withhold its consent to any extension of the Liquidity Event Deadline in its
sole discretion.

                                      -5-
<PAGE>

            3.5.2 RIGHT TO REQUIRE ARBITRATION. If Inktomi fails to consummate a
Liquidity Event in accordance with this Agreement by the Liquidity Event
Deadline (as the same may be changed under Section 3.5.1 above), and provided
that Inktomi has not previously exercised the Put Option, then Equity Office
shall have the right to obtain an Arbitration Determination of the Appraised
Value of the Bayside Project, by delivering written notice (the "ARBITRATION
NOTICE") of such election to Inktomi. In the event that the final Arbitration
Determination shows an Appraised Value in excess of the Base Value, then, within
five (5) days after the issuance of the Arbitration Determination, Inktomi shall
pay to Equity Office the Participation Payment based on the Arbitration
Determination. Promptly upon Inktomi's payment of the Participation Payment,
Equity Office shall reconvey and release the Participation Deed of Trust. In the
event that the final Arbitration Determination shows an Appraised Value equal to
or less than the Base Value, then, within five (5) days after the issuance of
the Arbitration Determination, Equity Office shall reconvey and release the
Participation Deed of Trust.

      3.6   ARBITRATION PROCEDURE.

            3.6.1 ARBITRATION AFTER LIQUIDITY CLOSING. If there is a Liquidity
Event under circumstances where the Release Amount is held by the Escrow Holder
after the Liquidity Closing, references in this Section 3.6 to "Estimates" shall
refer to Equity Office's estimate of the Appraised Value delivered under Section
3.1.3 above and Inktomi's estimate of the Appraised Value delivered pursuant to
Section 3.4.2 above. In such case, the parties shall arbitrate the question of
the Appraised Value, utilizing the procedures outlined beginning at Section
3.6.3 below.

            3.6.2 ARBITRATION WITHOUT LIQUIDITY EVENT. If Equity Office
initiates arbitration without there being a Liquidity Event, then within five
(5) days after the delivery of the Arbitration Notice, each party shall
simultaneously submit to the other, in a sealed envelope, its good faith
estimate of the Appraised Value of the Bayside Project and the corresponding
Participation Payment (if any) Equity Office is entitled to receive in
satisfaction of its Participation Interest. Where arbitration is conducted
without a Liquidity Event, references in this Section 3.6 to "Estimates" shall
refer to the estimates so exchanged by Equity Office and Inktomi. If the higher
of such Estimates is such that the associated Participation Payment is not more
than 105% of Participation Payment associated with the lower of such Estimates,
then the Participation Payment shall be determined based upon the average of the
two Estimates. If the amount of the Participation Payment is not resolved by the
exchange of Estimates, then, within seven (7) days after the exchange of
Estimates, the parties shall proceed as outlined beginning in Section 3.6.3
below.

            3.6.3 SELECTION OF APPRAISERS. Inktomi and Equity Office shall each
select an appraiser to determine which of the two Estimates most closely
reflects the Appraised Value and the Participation Payment to which Equity
Office is entitled based on such Appraised Value. Each appraiser so selected
shall be certified as an MAI appraiser or as an ASA appraiser and shall have had
at least five (5) years experience within the previous ten (10) years as a real
estate appraiser working in the San Francisco Bay Area, with working knowledge
of current market conditions and practices. For purposes hereof, an "MAI"
appraiser means an individual who holds an MAI designation conferred by, and is
an independent member of, the American Institute

                                      -6-
<PAGE>
of Real Estate Appraisers (or its successor organization, or in the event there
is no successor organization, the organization and designation most similar),
and an "ASA" appraiser means an individual who holds the Senior Member
designation conferred by, and is an independent member of, the American Society
of Appraisers (or its successor organization, or, in the event there is no
successor organization, the organization and designation most similar). Upon
selection, the two (2) appraisers selected by the parties shall work together in
good faith to agree upon which of the two Estimates most closely reflects the
Appraised Value. If either party fails to appoint an appraiser within the seven
(7) day period referred to in Section 3.6.2 above, the appraiser appointed by
the other party shall be the sole appraiser for the purposes hereof. If the two
appraisers cannot agree upon which of the two Estimates most closely reflects
the Appraised Value and the corresponding Participation Payment within twenty
(20) days after their appointment, then, within ten (10) days after the
expiration of such twenty (20) day period, the two appraisers shall select a
third appraiser meeting the aforementioned criteria. If the appraisers are not
able to agree upon a third appraiser within such ten (10) day period, then they
shall ask the American Institute of Real Estate Appraisers, or successor
organization, to provide a list of five (5) qualified appraisers. Beginning with
the appraiser appointed by Inktomi, each appraiser shall, within three (3)
business days, strike the name of one (1) of the five (5) appraisers on such
list, and the appraiser remaining after each appraiser has stricken two (2)
names shall be the third appraiser. Once the third appraiser (the "ARBITRATOR")
has been selected as provided for above, then, as soon thereafter as practicable
but in any case within fourteen (14) days, the Arbitrator shall make his or her
determination of which of the two Estimates most closely reflects the Appraised
Value, and the corresponding Participation Payment. If the Arbitrator believes
that expert advice would materially assist him or her, he or she may retain one
or more qualified persons to provide such expert advice. Each of Equity Office
and Inktomi initially shall pay the costs of the Arbitrator and of any experts
retained by the Arbitrator. Any fees of any appraiser, counsel or experts
engaged directly by Equity Office or Inktomi initially shall be borne by the
party retaining such appraiser, counsel or expert. The Appraised Value and the
corresponding Participation Payment agreed upon by the appraisers, or determined
by the Arbitrator, is referred to herein as the "ARBITRATION DETERMINATION." The
party whose Estimate is selected as most closely reflecting the Appraised Value
shall be entitled to recover from the other party its one-half share of the
Arbitrator's costs (including costs of experts retained by the Arbitrator) and
all reasonable attorneys', appraisers' and experts' fees incurred by such party
in connection with the Arbitration Determination.

            3.6.4 DELIVERY OF INFORMATION TO APPRAISER. Within ten (10) days
after the appointment of the appraisers, Inktomi shall deliver to each
appraiser, with copies to Equity Office (except to the extent such materials
have been delivered to Equity Office previously), the following documents (the

<PAGE>

                        (iii) LEASES AND ESTOPPELS. Complete copies of all
                  leases encumbering the Bayside Project, and all amendments or
                  modifications thereto, together with the most current estoppel
                  certificates from (i) Legacy Partners L.P., and (ii) PE
                  Corporation (NY) (formerly named The Perkin-Elmer
                  Corporation), which entities are currently occupying portions
                  of the Bayside Project (collectively, the "Current Tenants").

                        (iv)  BUILDING RECORDS. Copies of the most current
                  operating statements and tax bills.

                  Inktomi shall, within ten (10) days after request by the
appraisers, provide the appraisers with reasonable access to other materials,
information or documentation reasonably requested by the appraisers in forming
their opinions as to Value, including all business licenses and permits, the
Bayside Project certificate of occupancy, and evidence of the Bayside Project's
compliance with applicable zoning and use laws and regulations. Inktomi may
require that all recipients of the Diligence Documents first sign a customary
confidentiality agreement to assure that the data supplied or made available by
Inktomi are used solely for the purposes contemplated by this Section 3.6.

            3.6.5 ENTRY. Inktomi shall allow the appraisers to enter the Bayside
Project at reasonable times upon reasonable prior notice and to make such
investigations and surveys as the appraisers reasonably determine to be
appropriate in connection with the Arbitration Determination.

            3.6.6 ARBITRATION DETERMINATION. The Arbitration Determination shall
establish the Participation Payment based upon the Appraised Value of the
Bayside Project as of the Participation Date, which Appraised Value shall be the
"fair market value" of the Bayside Project, assuming an arms' length sale of the
Bayside Project to an unaffiliated third party, accompanied by a Lease-Back by
Inktomi on the same basic economic terms (consisting of the lease term, base
rent, pass through of operating expenses and taxes, amount of letter of credit
security, rights to renew and renewal rent) as are contained in the Lease-Back
Lease, and assuming the Current Tenants are in occupancy, and otherwise on such
terms as would be consistent with a transaction conforming to market terms in
effect on the Participation Date, and in conformance with commercially
reasonable, industry standard appraisal procedures applied when appraising an
office property. The appraisers shall render the Arbitration Determination
within forty-five (45) days after the date of their appointment. The Arbitration
Determination shall be the final determination of the Appraised Value of the
Bayside Project and the corresponding Participation Payment, and shall be
binding and conclusive as between Equity Office and Inktomi. Notwithstanding the
foregoing, if prior to the Arbitration Determination, Inktomi (i) tenders to
Equity Office either (A) if Equity Office has approved a Liquidity Event, the
amount Equity Office has approved as the Participation Payment in connection
with such Liquidity Event, or (B) if Equity Office has not approved a Liquidity
Event, the Estimate of Participation Payment calculated by Equity Office and
submitted under Section 3.1.3 or Section 3.6.2, and (ii) agrees to promptly
reimburse Equity Office, upon presentation of an invoice therefor (together with
reasonable supporting documentation) for all amounts Equity Office has incurred
and could recover as the party prevailing in the Arbitration Determination, the
arbitration shall

                                      -8-
<PAGE>
be cancelled and such Participation Payment will fully satisfy and forever
release and discharge the Participation Interest.

      3.7   AUTHORIZED TRANSFERS. Each of the following shall be an "AUTHORIZED
TRANSFER" by Inktomi: (i) any sale or other transfer of the Bayside Project to
an entity which controls Inktomi, is controlled by Inktomi, or is under common
control with Inktomi; (ii) any sale or other transfer of the Bayside Project in
connection with a merger, consolidation or reorganization or a sale of all or
substantially all of Inktomi's assets as a going concern, provided the
creditworthiness of the surviving entity or asset purchaser is comparable to
Inktomi's creditworthiness on the date of this Agreement; and (iii) any
modification of the existing leases with the Current Tenants and any new lease
of the Bayside Project, in each case made with Equity Office's prior written
consent, which shall not be unreasonably withheld, conditioned or delayed.
Notwithstanding the preceding clause (iii), Equity Office acknowledges that it
has reviewed and approved a proposed second amendment to the existing lease with
PE Corporation (NY) (formerly named The Perkin-Elmer Corporation) which was
delivered to Anton N. Natsis by Sherry Geyer under cover of e-mail, dated
September 5, 2002, and, provided there is no material change to such proposed
amendment, and provided that the provision dealing with the right of first offer
is substantially similar to that contained therein, Inktomi may enter into such
amendment without Equity Office's consent, and the same shall be an Authorized
Transfer.

      3.8   NO ASSURANCES AS TO VALUE. Equity Office acknowledges that Inktomi
has made no statements, representations or other assurances regarding the Value
of the Bayside Project, and that Equity Office is entering to this Agreement
solely in reliance on its own investigation and evaluation concerning the Value
of the Bayside Project.

      3.9   EFFECT OF NOTE DEED OF TRUST FORECLOSURE. The parties acknowledge
and intend that the foreclosure of the Note Deed of Trust will extinguish the
Participation Deed of Trust. However, if the Note Deed of Trust is foreclosed
and neither Equity Office nor any affiliate of Equity Office is the foreclosure
purchaser, the Participation Interest shall survive the Note Deed of Trust
foreclosure. In such case the Participation Payment shall be based on the
Appraised Value of the Bayside Project using the date of the foreclosure sale as
the Participation Date. References in this Agreement to "foreclosure" shall
include judicial foreclosure, exercise of private power of sale and like
remedies.

4.    GRANT OF PUT OPTION. Equity Office hereby grants Inktomi the Put Option,
which upon exercise by Inktomi will obligate Equity Office to purchase fee title
in the Bayside Project from Inktomi, on the terms and conditions set forth in
this Section 4. Upon exercise of the Put Option, Equity Office's Participation
Interest shall be extinguished and forever released and discharged.

      4.1   PUT PURCHASE PRICE. The purchase price payable to Inktomi in
connection with Equity Office's purchase of the Bayside Project pursuant to the
Put Option shall be $37,500,000.00 (the "PUT PURCHASE PRICE"), which Put
Purchase Price shall be paid at the consummation of the sale of the Bayside
Project by Inktomi to Equity Office, less only reasonable and customary closing
costs, and reasonable and customary prorations to be added or deducted in
determining the net Put Purchase Price, all as allocated in the Put Purchase
Agreement. At the option of Equity Office, if as of the closing of the sale to
Equity Office of the Bayside Project in accordance with the terms of this
Section 4, any of the principal balance of the

                                      -9-
<PAGE>
Note remains outstanding (the "OUTSTANDING BALANCE"), Equity Office shall have
the right to pay such Outstanding Balance to the holder of the Note, and credit
the amount of such payment against the Put Purchase Price payable to Inktomi at
the closing of the sale.

      4.2   EXERCISE OF PUT OPTION. In the event that Inktomi desires to
exercise the Put Option, Inktomi shall deliver written notice of such exercise
(the "PUT EXERCISE NOTICE") to Equity Office, which delivery shall not be prior
to November 1, 2002, and shall, in any event be on or before January 21, 2003
(the "PUT TERMINATION DATE"). In the event that Inktomi has not delivered the
Put Exercise Notice on or before the Put Termination Date, then the Put Option
granted to Inktomi herein shall terminate and be of no further force or effect.
Concurrently with the delivery of the Put Exercise Notice, Inktomi shall deliver
the following documents.

            4.2.1 PUT PURCHASE AGREEMENT. Inktomi shall deliver to Equity Office
three (3) copies of a purchase and sale agreement (the "PUT PURCHASE AGREEMENT")

"LEASE-BACK LEASE") in the form attached hereto as EXHIBIT D, executed by
Inktomi. The Lease-Back Lease shall become effective upon the close of the sale
of the Bayside Project to Equity Office pursuant to the Put Purchase Agreement.

            4.2.3 LETTER OF CREDIT. Inktomi shall deliver to the "Escrow Holder"
as defined in the Put Purchase Agreement a letter of credit (the "LEASE LETTER
OF CREDIT") in the amount of six (6) months base rent and estimated operating
and tax expenses (which shall be deemed to be $1.00 per rentable square foot per
month for this purpose) and otherwise in the form required by the Lease-Back
Lease.

            4.2.4 DILIGENCE DOCUMENTS. Inktomi shall deliver to Equity Office
all of the Diligence Documents as defined in Section 3.5.2, above (except to the
extent such Diligence Documents have been delivered to Equity Office
previously).

      4.3   ACCEPTANCE OF PUT PURCHASE AGREEMENT. Within five (5) business days
after Equity Office's receipt of the Put Exercise Notice, Equity Office shall
promptly execute the Put Purchase Agreement, and deliver one (1) fully executed
original of the Put Purchase Agreement to Inktomi, and one (1) fully executed
original of the Put Purchase Agreement to "Escrow Holder", as defined in the Put
Purchase Agreement, and shall cause the Escrow Holder to open the "Escrow" as
defined in the Put Purchase Agreement, at which point the terms of the Put
Purchase Agreement shall be in full force and effect and binding upon the
parties. Concurrently with such delivery, Equity Office shall execute all three
(3) copies of the Lease-Back Lease, and deliver the same to Escrow Holder, to be
held in accordance with the terms of the Put Purchase Agreement. The purchase of
the Bayside Project by Equity Office shall thereafter proceed in accordance with
the terms of the Put Purchase Agreement.

      4.4   PERSONAL TO INKTOMI. The Put Option is personal to Inktomi, and may
not be assigned or transferred to any other party, except for any transferee
under an Approved Transfer of the types described in clauses (i) and (ii) of
Section 3.7 above.

<PAGE>

      4.5   TERMINATION OF PUT PURCHASE AGREEMENT. In the event that the Put
Purchase Agreement is terminated as a result of (i) a failure of a "Put
Condition", as that term is defined in Section 2.2 of the Put Purchase
Agreement, the satisfaction of which condition is outside of the reasonable
control of Inktomi, or (ii) a default under the Put Purchase Agreement by Equity
Office (or its assignee under the Put Purchase Agreement), the maturity date of
the Note shall be extended to be June 30, 2003.

5.    INVALIDITY. Wherever possible, each provision of this Agreement shall be
interpreted in such a manner as to be valid under applicable law, but, if any
provisions of this Agreement shall be invalid or prohibited thereunder, such
invalidity or prohibition shall be construed as if such invalid or prohibited
provisions had not been inserted herein and shall not affect the remainder of
such provision or the remaining provisions of this Agreement.

accordance with the laws of the State of California.

10.   ATTORNEYS' FEES. If any action is brought by either party against the
other party to interpret or enforce any of the terms of this Agreement, or in
the case of an Arbitration Determination, the prevailing party shall be entitled
to recover from the other party reasonable attorneys' fees, costs and expenses
incurred in connection with the prosecution or defense of such action, whether
or not the action is prosecuted to a final judgment. For purposes of this
Agreement, the term "attorneys' fees" shall mean the reasonable fees and
expenses of counsel to the parties hereto, which may include printing,
photostatting, duplicating and other expenses, air freight charges, and fees
billed for law clerks, paralegals and other persons not admitted to the bar but
performing services under the supervision of an attorney.

written. This Agreement may not be altered, amended, modified or otherwise
changed in any respect whatsoever, except by a writing duly executed by all of

                     ASSIGNMENT OF RENTS AND FIXTURE FILING

      THIS SECOND LIEN DEED OF TRUST ("Deed of Trust") is made as of September
5, 2002, by Inktomi Corporation, a Delaware corporation ("Trustor"), whose
address is 4100 East 3rd Avenue, Foster City, California, in favor of First
American Title Insurance ("Trustee"), whose address is 135 Main Street, Suite

in common between GATEWAY PHOENIX ASSOCIATES, L.P., a California limited

partnership ("Beneficiary"), whose address is set forth in Paragraph 7.14 below.

      NOTE: THIS DEED OF TRUST IS SPECIFICALLY MADE SUBJECT AND SUBORDINATE TO
THAT CERTAIN DEED OF TRUST ("FIRST DEED OF TRUST") EXECUTED BY TRUSTOR IN FAVOR
OF FIRST AMERICAN TITLE INSURANCE WHICH WAS RECORDED ON _____________ IN THE
OFFICIAL RECORDS OF SAN MATEO COUNTY, CALIFORNIA AS INSTRUMENT NO. _____________

                                       I.

                                 GRANT IN TRUST

      1.01  Trustor irrevocably grants, conveys, transfers and assigns to
Trustee, in trust, with power of sale and right of entry and possession, all
right, title and interest which Trustor now has or may hereafter acquire in and
to that certain real property (the "Subject Property") located at 4000 and 4100
Third Avenue, Foster City, California, as more particularly described on Exhibit
"A" attached hereto and incorporated herein by reference, together with all
easements and other rights now or hereafter located thereon or appurtenant
thereto, all buildings situated on the Subject Property, together with all
appurtenances and all other existing or subsequently erected improvements in,
under or upon the Subject Property, all development rights or credits and air
rights, all fixtures, all additions and accretions thereto, and any greater
estate in the

                                      -1-
<PAGE>
Subject Property or any part thereof now owned or hereafter acquired by Trustor.
Trustor makes the foregoing grant to Trustee to hold the Subject Property in
trust for the benefit of Beneficiary, and for the purpose and upon the terms and
conditions hereinafter set forth.

                                       II.

                               ASSIGNMENT OF RENTS

      2.01  Trustor absolutely and irrevocably assigns to Beneficiary the rents,
issues, deposits and profits of the Subject Property, together with the
immediate and continuing right to collect and receive the same, for the purposes
and upon the terms and conditions hereinafter set forth. The foregoing
assignment shall not impose upon Beneficiary any duty to produce rents from the
Subject Property, and said assignment shall not cause Beneficiary to be a
"mortgagee in possession" for any purpose.

                                      III.

                                 FIXTURE FILING

      3.01  This Deed of Trust encumbers, and Trustor hereby grants Beneficiary
a security interest in, all personal property of any kind whatsoever, which is
now or becomes a "fixture" and which is used or will be used in construction of,
or is or will be placed upon or is derived from or used in any connection with
the use, occupancy or enjoyment of, the Subject Property. "Fixtures" shall
include all articles of personal property, furniture and furnishings which are
so related to the Subject Property such that an interest arises in them under
the real estate laws of the State of California. To the extent of the existence
of personal property encumbered by the Deed of Trust, this Deed of Trust

in such personal property in favor of Beneficiary and to constitute a "fixture
filing" in accordance with the provisions of Section 9313 of the Uniform
Commercial Code in effect in the State of California. This Deed of Trust shall
be self-operative with respect to such personal property, but Trustor agrees to
execute and deliver on demand such security agreements, financing statements and
other instruments as Beneficiary may request in order to impose the lien hereof
more specifically upon any of such property.

                                       IV.

and/or performance of such further obligations as Trustor may undertake to pay

      4.03  Performance of each agreement of Trustor herein contained or
contained in the Participation Agreement, and the payment of each fee, cost and
expense by Trustor as herein set forth.

      TO PROTECT THE SECURITY OF THIS DEED OF TRUST, THE PARTIES AGREE AS
FOLLOWS:

                                       V.

                        RIGHTS AND DUTIES OF THE PARTIES.

      5.01  Warranties by Trustor. Trustor is a corporation duly organized and
existing under the laws of the State of Delaware and qualified to do business in
the State of California. Trustor warrants that Trustor is the lawful owner of
the Subject Property in fee simple, without limitation on its right to encumber.

      5.02  Taxes and Assessments. Trustor shall pay or cause to be paid prior
to delinquency all real property taxes, assessments, levies and charges imposed
by any public or quasi-public authority or utility company which are or may
become a lien upon the Subject Property, any part thereof or interest therein.
Trustor shall also pay when due all real property taxes, assessments, levies and
charges imposed by any public authority upon Beneficiary by reason of its
interest in the Subject Property created hereby; provided, however, that Trustor
shall have no obligation to pay or discharge taxes which may be imposed from
time to time upon Beneficiary and which are measured by and imposed upon
Beneficiary's net income. Upon written request of Beneficiary, Trustor shall
provide Beneficiary with evidence of such payment. Trustor shall have the right
to contest in good faith any such real property taxes, assessments, levies or
charges provided that it does so diligently and without prejudice to
Beneficiary.

      As used herein, the term "real property taxes" shall include any form of
assessment, possessory interest tax, license fee, license tax, business license
fee, business license tax, commercial rental tax, levy, charge, penalty, tax or
similar imposition imposed by any authority having the direct power to tax,
including any city, county, state or federal government, or any school,
agricultural, lighting, drainage or other improvement or special assessment
district thereof, as against any legal or equitable interest of Trustor in the
Subject Property, including, but not limited to, the following:

      (a)   Any assessment, tax, fee, levy or charge in substitution, partially
      or totally, of any assessment, tax, fee, levy or charge previously
      included within the definition of real property tax. It is the intention
      of Trustor and Beneficiary that all such new and increased assessments,
      taxes, fees, levies and charges and all similar assessments, taxes, fees,
      levies and charges be included within the definition of real property
      taxes for the purposes of this Deed of Trust;

                                      -3-
<PAGE>
      (b)   Any assessment, tax, fee, levy or charge allocable to the operation
      of or measured by the area of the Subject Property, including, without
      limitation, any gross income tax or excise tax levied in lieu of real
      property taxes by the state, city or federal government, or any political
      subdivision thereof, with respect to the possession, leasing, operating,
      management, maintenance, alteration, repair, use or occupancy of the
      Subject Property, or any portion thereof; and

      (c)   Any assessment, tax, fee, levy or charge upon this transaction or
      any document creating or transferring any interest or an estate in the
      Subject Property.

      5.03  Impounds for Insurance Premiums and Taxes. After the occurrence of
an Event of Default, at Beneficiary's option, Trustor shall pay to Beneficiary
monthly, on or before the fifth (5th) of each month, 1/12 of such amount as
Beneficiary from time to time estimates will be required to pay all taxes
required to be paid by Paragraph 5.02 and insurance premiums for insurance
required by Paragraph 5.04. Beneficiary's estimates shall be based on the
amounts actually payable or, if unknown, on the amounts actually paid for the
year preceding that for which such payments are being made. Any deficiencies
shall be promptly paid by Trustor to Beneficiary on demand. Trustor shall
transmit bills for the taxes and insurance premiums as soon as received. When
Beneficiary has received from Trustor or on its account funds sufficient to pay
the same, Beneficiary shall pay such bills. If the amount paid by Trustor in any
year exceeds the aggregate required, such excess shall be applied to impound
payments for the succeeding year. Beneficiary shall not be a trustee of funds in
said account and may commingle such funds with its general assets without any
obligation to pay interest thereon or account for any earnings, income or
interest on such funds.

      5.04  Insurance. Trustor shall at all times provide, maintain and keep in
force (i) commercial general public liability in the amount of at least
$5,000,000.00 and property damage coverage with a broad form coverage
endorsement and also breach of warranty coverage; (ii) protection against fire,
"extended coverage" and other "all risk" perils, including earthquake, and, if
the improvements are located in a flood hazard area, flood insurance on the
improvements, all in an amount equal to the full replacement value of all real
and personal property and improvements as determined by Beneficiary; (iii) rent
loss insurance in the amount of gross pro forma income for twelve (12) months;
(iv) insurance against loss or damage from leakage of sprinkler systems, air
conditioning equipment or other equipment now or hereafter installed in or on
the Subject Property; (v) during the course of any construction of or repairs to
the improvements or personal property, builders course of construction and
completed value insuring each name insured against "all risks of physical loss"
and worker's compensation insurance and any other employee benefit insurance
required by law, for all employees of Trustor engaged on or with respect to the
Subject Property in such amount as is reasonably satisfactory to Beneficiary, or
if such limits are established by law, in such amounts; and (vi) such other
insurance as Beneficiary may reasonably require insuring against loss which at
the time is commonly insured against and generally available at commercially
reasonable rates in the case of premises similarly situated, with due regard
being given to the height and type of improvements, the personal property and
the location, construction, use and occupancy thereof.

      5.05  Terms of Insurance. All policies of insurance required by the terms
of this Deed of Trust, or otherwise carried by Trustor and applicable to the
Property (except the employee benefit and public liability insurance which shall
name Beneficiary as an additional insured)

                                      -4-
<PAGE>
shall contain a lender's loss payable endorsement for the benefit of
Beneficiary, which shall provide that (i) all insurance proceeds shall be paid
to Beneficiary and Beneficiary shall be authorized and empowered by Trustor to
settle, adjust or compromise any claims for loss, damage or destruction under
such policies of insurance, (ii) any loss covered by such insurance shall be
payable by the insurer in accordance with the terms of such policy
notwithstanding any act or negligence of Trustor, its agents or employees, the
named insured, or any owner, tenant, or occupant of the Subject Property which
might otherwise result in forfeiture of said insurance, (iii) the insurer waives
all rights of setoff, counterclaim or deduction against Trustor, and (iv) should
legal title to and beneficial ownership of the Subject Property become vested in
Beneficiary, the insurance provided by such policies shall continue for the term
thereof for the benefit of Beneficiary. All required insurance shall provide (i)
a waiver of subrogation endorsement in a form satisfactory to Beneficiary; (ii)
the insurance afforded all parties named as insured shall be primary insurance
and shall not participate with, nor be in excess over, any other valid and
collectible insurance available to Beneficiary; (iii) any other insurance
obtained by any named insured shall not be called upon to contribute until the
limits of the policies required hereunder are exhausted; (iv) the insurance
required hereunder cannot be cancelled or materially amended or altered without
at least thirty (30) days prior written notice to Beneficiary; and (v) the
insurer shall notify Beneficiary, within thirty (30) days prior to the
expiration of any policy, of Trustor's failure to renew such policy; and (vi)
with respect to the fire and "extended coverage" insurance, a replacement cost
endorsement, an agreed amount endorsement, and an inflation guard endorsement,
all in a form satisfactory to Beneficiary. All insurance required hereunder
shall be issued by companies approved in advance by Beneficiary and rated at
least A-VIII by a current Best's Insurance Guide, and such insurance shall be in
the form and on terms (including but not limited to deductibles, self-insured
retentions, or similar provisions) reasonably approved in advance by
Beneficiary.

      5.06  Delivery of Policies, Payment of Premiums. Trustor shall furnish
Beneficiary with a certificate of insurance evidencing the insurance required
hereunder and naming Beneficiary as additional insured. If Trustor elects to
provide any of the required insurance through blanket policies carried by
Trustor and covering more than one location, then Trustor shall furnish
Beneficiary with a certificate of insurance for each such policy setting forth
the coverage, the limits of liability, the aggregate amount of all claims paid
under said policy, the nature of the carrier, the policy number, and the
expiration date. At least thirty (30) days prior to the expiration of each
required insurance policy (without regard to any grace period for nonpayment of
premium), Trustor shall furnish Beneficiary with evidence satisfactory to
Beneficiary of the payment of the premium and the reissuance of a policy
continuing in force without lapse or reduction in coverage.

      5.07  Insurance Proceeds. Trustor hereby agrees that after the happening
of any casualty to the Subject Property or any part thereof, Trustor shall give
prompt written notice thereof to Beneficiary.

      (a)   Trustor hereby assigns its interest in all insurance proceeds to
      Beneficiary and authorizes and directs any affected insurance company to
      make payment of such proceeds directly to Beneficiary. Trustor shall
      obtain Beneficiary's approval, which approval shall not be unreasonably
      withheld or delayed, prior to any settlement, adjustment or compromise of
      any claims for loss, damage or destruction under any policy or policies of
      insurance, and Beneficiary shall have

                                      -5-
<PAGE>
      the right to participate with Trustor in negotiation of any such
      settlement, adjustment or compromise. Beneficiary shall also have the
      right to appear with Trustor in any action against an insurer based on a
      claim for loss, damage or destruction under any policy or policies of
      insurance.

      (b)   All compensation, awards, proceeds, damages, claims, insurance
      recoveries, rights of action and payments which Trustor may receive or to
      which Trustor may become entitled with respect to the Subject Property or
      any part thereof (herein the "Proceeds") shall be paid over to the
      Beneficiary. In the event such loss or damage is less than Fifty Thousand
      Dollars ($50,000.00) the Proceeds will be paid to Trustor by Beneficiary
      and Trustor agrees to promptly thereafter repair and/or replace such
      damage or loss. In the event of a loss greater than Fifty Thousand Dollars
      ($50,000.00) ("Major Damage"), Beneficiary shall apply the Proceeds to the
      repair, replacement or restoration of the Subject Property in which event
      Beneficiary shall disburse the Proceeds in accordance with the procedures
      set forth in subparagraph (c) below. If there are any Proceeds in excess
      of the amount necessary to repay the amount secured hereunder and all
      other amounts secured hereby, then such excess Proceeds shall be paid to
      Trustor.

      (c)   Beneficiary shall disburse Proceeds to Trustor in connection with
      Major Damage, upon the satisfaction of the following conditions
      ("Disbursement Conditions"):

            (i)   Proceeds have been deposited with the Beneficiary;

            (ii)  Beneficiary shall have been furnished with a reasonable
            estimate of the cost of restoration accompanied by a certificate
            from a party acceptable to Beneficiary as to such costs and
            appropriate final plans and specifications for reconstruction of the
            improvements, if necessary, all of which shall be approved by
            Beneficiary;

            (iii) the improvements so restored or rebuilt shall be of
            substantially the same character and value as prior to the damage or
            destruction and appropriate for the purposes for which they were
            originally erected;

            (iv)  Trustor shall have furnished Beneficiary with evidence
            satisfactory to Beneficiary that all improvements so restored and/or
            reconstructed and their use shall fully comply with all zoning,
            building and use laws, ordinances and regulations;

            (v)   If the estimated cost of restoration exceeds the Proceeds
            available, Trustor shall have furnished a satisfactory bond of
            completion or deposited with Beneficiary such sums as may be
            necessary to pay such excess costs;

            (vi)  Beneficiary shall have received notice within thirty (30) days
            after the fire or other hazard or of the condemnation proceedings
            specifying the date of such fire or other hazard or the date the
            notice of condemnation proceedings was received;

                                      -6-
<PAGE>
            (vii) Trustor shall not then be in default under the Participation
            Agreement or this Deed of Trust,

then the Proceeds, less the actual costs, fees and expenses, if any, incurred in
connection with adjustment of loss and Beneficiary's administrative expenses
relating to the disbursement of the Proceeds shall be applied by Beneficiary to
the payment of all the costs of the aforesaid restoration, repairs, replacement,
rebuilding or alterations, (all of which are hereinafter collectively referred
to as the "Restoration"), and shall be paid out by Beneficiary from time to time
as such Restoration progresses upon the written request of Trustor accompanied
by the following:

            A certificate of an architect licensed in the State of California
            acceptable to Beneficiary, dated not more than thirty (30) days
            prior to such request, setting forth the following:

                  (A)   That the sum then requested either has been paid, or is
                  justly due to contractors, subcontractors, materialmen,
                  engineers, architects or other persons who have rendered
                  services or furnished materials for the restoration therein
                  specified or have paid for the same, the names and addresses
                  of such persons, a brief description of such services and
                  materials, the several amounts so paid or due to each of said
                  persons in respect thereof, that no part of such expenditures
                  has been or is being made on the basis of any previous or then
                  pending request for the withdrawal of Proceeds or has been
                  made out of any of the Proceeds received by Trustor, and that
                  the sum then requested does not exceed the value of the
                  services and materials described in the certificate.

                  (B)   That, except for the amount, if any, stated (pursuant to
                  the foregoing subclause (A)) in such certificate to be due for
                  services or materials, there is no outstanding indebtedness
                  known to the person signing such certification, after due
                  inquiry, which is then due for labor, wages, materials,
                  supplies or services in connection with such restoration.

                  (C)   That the costs, as estimated by the person signing such
                  certificate, of the Restoration required to be done subsequent
                  to the date of such certificate in order to complete and pay
                  for the same, do not exceed the Proceeds, plus any amount or
                  security approved by Beneficiary and deposited by Trustor to
                  defray such costs and remaining in the hands of the
                  Beneficiary after payment of the sum requested in such
                  certificate.

            Upon compliance with the foregoing provisions, Beneficiary shall,
            out of Proceeds (and the amount of security approved by Beneficiary,
            if any, deposited by Trustor to defray the costs of the
            Restoration), pay or cause to be paid to Trustor or the persons
            named (pursuant to Subclause (A) above) in such certificate the
            respective amounts (subject to subparagraph (e) below) stated
            therein to have been paid by Trustor or to be due to them, as the
            case may be.

      (d)   If the Proceeds at the time held by the Beneficiary, less
      the actual costs,

                                      -7-
<PAGE>
      fees and expenses, if any, incurred in connection with the adjustment of
      the loss and the Beneficiary's administrative expenses relating to such
      loss and the disbursement of the Proceeds, shall be, in Beneficiary's
      reasonable judgment insufficient to pay the entire cost of the
      Restoration, Trustor shall deposit with the Beneficiary any such
      deficiency prior to disbursement of any additional portion of the
      Proceeds.

      (e)   No payment made prior to the final completion of the Restoration
      shall exceed ninety percent (90%) of the value of the work performed from
      time to time, and at all times the undisbursed balance of said Proceeds
      remaining in the hands of the Beneficiary shall be at least sufficient to
      pay for the cost of completion of the Restoration free and clear of liens.

      (f)   Final payment shall be upon an architect's certificate of completion
      in accordance with the final plans and specifications and compliance with
      all zoning, building, subdivision and other governmental laws, ordinances,
      rules, and regulations, and the filing of a Notice of Completion and the
      receipt of Beneficiary of final lien releases for such work or the
      expiration of the period provided under California law for the filing of
      mechanic's and materialmen's liens. Beneficiary may at its option require
      an Endorsement to its title insurance policy insuring the continued
      priority of the lien of this Deed of Trust as to all sums advanced
      hereunder. The cost of such endorsement will be paid by Trustor.

      (g)   In the event of a "Condemnation" (as defined below), upon completion
      of the Restoration in a good and workmanlike manner in accordance
      herewith, and provided that Beneficiary has received satisfactory evidence
      that the Restoration has been paid for in full and the Subject Property is
      free and clear of all liens related to or in connection with the
      Restoration, any balance of the Proceeds at the time held by the
      Beneficiary (after reimbursement to Beneficiary of all costs and expenses
      of the Beneficiary, including administrative expenses, in connection with
      recovery of the same and disbursement of such Proceeds for the
      Restoration), if any, shall be applied as follows: (i) to the extent that
      such balance of the Proceeds is equal to or less than the amount, if any,
      by which the value of the Subject Property prior to such damage or
      destruction exceeds the value of the Subject Property after such
      Restoration (for these purposes, the value of the Subject Property shall
      be determined by Beneficiary in its discretion), then the portion of the
      balance of the Proceeds equal to such excess amount shall be applied to
      the payment or prepayment of the principal balance of the indebtedness
      outstanding under the Participation Agreement in such order as Beneficiary
      may determine, and any amounts so applied shall reduce the indebtedness
      secured hereby pro tanto; and (ii) to the extent that the balance of the
      Proceeds exceeds such excess amount, such excess portion of the balance of
      the Proceeds shall, at Beneficiary's option, be applied so as to reduce
      the indebtedness secured hereby or be paid to Trustor.

      (h)   Subject to Beneficiary releasing all available proceeds in
      accordance with the provisions of this Deed of Trust, nothing herein
      contained shall be deemed to excuse Trustor from repairing or maintaining
      the Subject Property as provided herein or restoring all damage or
      destruction to the Subject Property, regardless of whether or not there
      are insurance proceeds available or whether any such proceeds are
      sufficient in amount, and the application or release by the Beneficiary of
      any insurance proceeds shall not cure or waive any Event of Default, as
      hereinafter defined, or notice of default under this Deed of Trust or
      invalidate any other act done by Beneficiary to exercise its remedies
      hereunder.

                                      -8-
<PAGE>
      5.08  Condemnation. Should all or any part of the Subject Property or any
interest therein be taken or damaged by reason of any public improvement, by the
exercise of the power of eminent domain (whether by legal proceedings or
otherwise) by any person or entity having the legal power to do so, by a
voluntary sale or transfer either under threat of condemnation or while legal
proceedings for condemnation are pending, by inverse condemnation, or in any
other similar manner (collectively a "Condemnation"), or should Trustor receive
any notice or other information regarding a Condemnation (whether threatened or
pending), Trustor shall give prompt written notice thereof to Beneficiary. In
the event of a Condemnation:

      (a)   Beneficiary shall be entitled to, and is hereby assigned, all
      compensation, awards, damages, proceeds, or other payments or relief
      resulting therefrom (the "Condemnation Proceeds") to the extent of the
      principal balance of the indebtedness secured hereby together with any
      unpaid accrued interest thereon and other amounts due under the
      Participation Agreement or this Deed of Trust. Beneficiary shall also be
      entitled at its option to appear in, and prosecute in its own name any
      Condemnation action or proceedings, and to make any reasonable compromise
      or settlement thereof taking into account Trustor's interest in the
      Subject Property. Trustor agrees to execute such further assignments of
      the Condemnation Proceeds as Beneficiary or Trustee may require. Whether
      or not Beneficiary appears in or prosecutes in its own name any such
      action or proceeding, Trustor shall be responsible for representing, at
      its sole cost, its own interest therein. Trustor hereby specifically,
      unconditionally, and irrevocably waives all rights of a property owner
      under the provisions of Section 1265.225(a) of the California Code of
      Civil Procedure or any successor statute, providing for the allocation of
      Condemnation Proceeds between a property owner and a lienholder.

      (b)   Beneficiary shall have the option to apply all such Condemnation
      Proceeds, after deducting therefrom all costs and expenses incurred by it
      in connection with obtaining such Condemnation Proceeds, in the same
      manner and with the same effect provided for in paragraph 5.07 regarding
      the disposition of insurance proceeds. Such application or release shall
      not cure or waive any default or notice of default hereunder or invalidate
      any act done pursuant to such notice.

      5.09  Hazardous Materials Compliance, Notices, Inspections and
Indemnification. Trustor shall, and Trustor shall cause all tenants, employees,
agents, contractors and subcontractors of Trustor and any other persons present
on or occupying the Subject Property to, keep and maintain the Subject Property,
including the soil and ground water thereof, in compliance with, and not cause
or permit the Subject Property, including the soil and ground water thereof, to
be in violation of any federal, state or local laws, ordinances or regulations
relating to industrial hygiene or to the environmental conditions thereon
(including but not limited to any "Hazardous Materials Laws" as hereinafter
defined). Except in compliance with all applicable Hazardous Materials Laws,

or any other persons occupying or present (including tenants) on the Subject
Property shall use, generate, manufacture, store or dispose of on, under or
about the Subject Property or transport to or from the Subject Property any
flammable explosives, radioactive materials, hazardous wastes, toxic substances
or related materials, including, without limitation, any substances defined as

"hazardous wastes," "hazardous materials," or "toxic substances" under any
Hazardous Materials Laws (collectively referred to hereinafter as "Hazardous
Materials"), except for ordinary and customary materials used in the normal
course of construction, maintenance or use of the Property, so long a such
materials are used and/or stored in compliance with Hazardous Materials Laws.

      Trustor shall immediately advise Beneficiary in writing of: (i) any
notices (whether such notices are received from the Environmental Protection
Agency, the Occupational Safety and Health Agency, the Department of Health
Services, the State Water Quality Control Board, the Department of Sanitation,
the Department of Public Works or any other federal, state or local governmental
agency or regional office thereof) of violation or potential violation which are

Laws"); (ii) any and all enforcement, cleanup, removal or other governmental or
regulatory actions instituted, completed or threatened pursuant to any Hazardous
Materials Laws; (iii) all claims made or threatened in writing by any third
party against Trustor or the Subject Property relating to damage, contribution,
cost recovery compensation, loss or injury resulting from any Hazardous
Materials (the matters set forth in clauses (i), (ii) and (iii) above are
hereinafter referred to as "Hazardous Materials Claims"); and (iv) Trustor's
discovery of any occurrence or condition on any real property adjoining or in
the vicinity of the Subject Property that could cause the Subject Property or
any part thereof to be classified as "border-zone property" under the provisions
of California Health and Safety Code, Sections 25220 et seq. or any regulation
adopted in accordance therewith, or to be otherwise subject to any restrictions
on the ownership, occupancy, transferability or use of the Subject Property
under any Hazardous Materials Laws.

      Trustor shall be solely responsible for, and shall indemnify and hold
harmless Beneficiary, its directors, officers, employees, agents, successors and
assigns from and against, any loss, damage, cost, expense or liability directly
or indirectly arising out of or attributable to the use, generation, storage,
release, threatened release, discharge, disposal, or presence (whether prior to
or during the term of the loan secured by this Deed Trust) of Hazardous
Materials on, under or about the Property (whether by Borrower or a predecessor
in title or any employees, agents, contractors or subcontractors of Borrower or
any predecessor in title or any third persons at any time occupying or present,
including tenants, on the Subject Property), including, without limitation: (a)
all foreseeable and unforeseeable consequential damage, including third party
claims; (b) the costs of any required or necessary repair, cleanup or
detoxification of the Subject Property, including the soil and ground water
thereof, and the preparation and implementation of any closure, remedial or
other required plans; (c) damages to any natural resources; and (d) all
reasonable costs and expenses incurred by Beneficiary in connection with clauses
(a), (b) and (c), including but not limited to reasonable attorneys' and
consultants' fees.

                                      -10-
<PAGE>
      Any costs or expenses incurred by Beneficiary for which Trustor is
responsible or for which Trustor has indemnified Beneficiary shall be paid to
Beneficiary on demand, and failing prompt reimbursement, shall be added to the
indebtedness secured by this Deed of Trust.

      Trustor shall take any and all remedial action necessary in response to
the presence of any Hazardous Materials on, under, or about the Subject
Property, provided that in such event Trustor shall notify Beneficiary as soon
as practicable of any action so taken.

      If Beneficiary has reasonable cause (based on written notice) to believe
that a release, or the threat of a release, of any Hazardous Materials exists or
if an Event of Default has occurred and remains uncured, then upon Beneficiary's
request, Trustor shall retain, at Trustor's sole cost and expense, a licensed
geologist, industrial hygienist or an environmental consultant (referred to
hereinafter as the "Consultant") acceptable to Beneficiary to conduct a baseline
investigation of the Property for the presence of Hazardous Materials
("Environmental Audit"). The Environmental Audit shall be performed in a manner
reasonably calculated to discover the presence of Hazardous Materials
contamination; provided, however, such investigation shall be of a scope and
intensity no greater than a baseline investigation conducted in accordance with
the general standards of persons providing such services taking into
consideration the known uses of the Subject Property and property in the
vicinity of the Subject Property and any factors unique to the Subject Property.
The Consultant shall concurrently deliver the results of its investigation in
writing directly to Trustor and Beneficiary without prior consultation with
either party unless conducted in the presence of the other party. Such results
shall be kept confidential by both Trustor and Beneficiary unless legally
compelled or required to disclose such results or disclosure is reasonably
required in order to pursue rights or remedies provided herein or at law.

      If Trustor fails to pay for or obtain an Environmental Audit as provided
for herein, Beneficiary may, but shall not be obligated to, obtain the
Environmental Audit, and either demand reimbursement from Trustor or add the
cost thereof to the indebtedness secured by this Deed of Trust, in which case
interest shall accrue on such sum at the Default Rate from the date of demand.

      Trustor covenants to reasonably cooperate with the Consultant and to allow
entry and reasonable access to all portions of the Subject Property for the
purpose of Consultant's investigation. Trustor covenants to comply, at its sole
cost and expense, with all recommendations contained in the Environmental Audit,
including any recommendation for additional testing and studies to detect the
presence of Hazardous Materials, if Beneficiary requires the implementation of
the same.

      5.10  Liens and Encumbrances. Trustor shall pay or cause to be paid at or
prior to maturity, all obligations secured by or reducible to liens and
encumbrances which shall now or hereafter encumber or appear to encumber the
Subject Property or any part thereof, all claims for work or labor performed, or
materials or supplies furnished, in connection with any work of demolition,
alteration, improvement of or construction upon the Subject Property.
Beneficiary hereby expressly reserves the right to advance any and all funds
necessary to cure any and all such obligations and/or claims after providing
written notice to Trustor and a five (5) day opportunity to cure.

                                      -11-
<PAGE>
      5.11  Maintenance and Preservation of the Subject Property. Trustor
covenants (i) to keep the Subject Property in good condition and repair; (ii)
not to remove or demolish the Subject Property or any part thereof; (iii) to
complete or restore promptly and in good and workmanlike manner the Subject
Property or any part thereof which may be damaged or destroyed; (iv) to comply
with and not suffer violations of (a) all laws, ordinances, regulations,
standards, and (b) all covenants, conditions, restrictions and equitable
servitudes, whether public or private, of every kind and character, and (c) all
requirements of insurance companies and any bureau or agency which establishes
standards of insurability, which laws, covenants or requirements affect the
Subject Property and pertain to acts committed or conditions existing thereon,
including, but without limitation, such work or alteration, improvement or
demolition as such laws, covenants or requirements mandate; (v) not to commit or
permit waste thereof; (vi) to do all other acts which from the character or use
of the Subject Property may be reasonably necessary to maintain it in the
condition (reasonable wear and tear excepted) as of the date of this Deed of
Trust; (vii) to perform all obligations required to be performed by Trustor
pertaining to the Subject Property, including, but not limited to, any and all
leases or subleases of which Trustor is or shall be the lessor or sublessor (and
in the event of default, all right, title and interest of Trustor under any such
leases or subleases and any and all other agreements affecting the Subject
Property in which Trustor shall have an interest shall be and hereby are
automatically assigned to Beneficiary hereunder, together with any deposits made
in connection therewith); (viii) not to create any deed of trust or encumbrance
upon the Subject Property subsequent hereto; and (ix) to execute, and where
appropriate acknowledge, and deliver such further instruments as Beneficiary or
Trustee deems necessary or appropriate to preserve, continue, perfect and enjoy
the security provided for herein, including, but without limitation, assignments
of Trustor's interest in leases or subleases of the Subject Property.

      5.12  Defense and Notice of Actions. Trustor shall, without liability,
cost or expense to Beneficiary or Trustee, protect, preserve and defend
Trustor's fee interest in and to the Subject Property, the security hereof or
the rights or powers of Beneficiary or Trustee hereunder. Said protection,
preservation and defense shall include protection, preservation and defense
against all adverse claimants to Trustor's interest in the Subject Property
whether or not such claimants or encumbrances assert title paramount to that of
Trustor or claim their interest on the basis of events or conditions arising
subsequent to the date hereof. Trustor shall give Beneficiary and Trustee prompt
notice in writing of the filing of any such action or proceeding.

      5.13  Collection of Rents, Issues and Profits. Beneficiary confers upon
Trustor a license to collect and retain the rents, issues and profits of the
Subject Property as they become due and payable, subject, however, to the right
of Beneficiary upon default hereunder to revoke said authority at any time in
its sole discretion and without notice to Trustor. Beneficiary may revoke said
authority and collect and retain the rents, issues and profits of the Subject
Property assigned herein to Beneficiary upon the occurrence of an Event of
Default hereunder or under any of the obligations secured hereby, and without
taking possession of all or any part of the Subject Property, and without
prejudice to or limitation upon any of its additional rights and remedies
granted pursuant hereto or pursuant to the Participation Agreement or this Deed
of Trust.

      5.14  Right of Inspection. Subject to the rights of tenants under their
respective leases, Beneficiary, its agents or employees, may enter the Subject
Property at any reasonable time for

                                      -12-
<PAGE>
the purpose of inspecting the Subject Property and ascertaining Trustor's
compliance with the terms hereof.

      5.15  Acceptance of Trust, Notice of Indemnification. Trustee accepts this
trust when this Deed of Trust, duly executed and acknowledged, becomes a public
record as provided by law. Trustee is not obligated to notify any party hereto
of pending sale under any other deed of trust or of any action or proceeding in
which Trustor, Beneficiary or Trustee shall be a party unless Trustee brings
such action. Trustee shall not be obligated to perform any act required of it
hereunder unless the performance of such act is requested in writing and Trustee
is reasonably indemnified against loss, cost, liability and expense.

      5.16  Powers of Trustee. From time to time upon written request of
Beneficiary and presentation of this Deed of Trust for endorsement, and without
affecting the personal liability of any person for payment of any indebtedness
or performance of the obligation secured hereby, Trustee may, without liability
therefor and without notice (i) reconvey all or any part of the Subject
Property; (ii) consent to the making of any map or plat thereof; (iii) join in
granting any easement thereon; (iv) join in any declaration of covenants and
restrictions; or (v) join in any extension agreement or any agreement
subordinating the lien or charge hereof. Trustee or Beneficiary may from time to
time apply to any court of competent jurisdiction for aid and direction in the
execution of the trusts hereunder and the enforcement of the rights and remedies
available hereunder, and Trustee or Beneficiary may obtain orders or decrees
directing or confirming or approving acts in the execution of said trusts and
the enforcement of said remedies. Trustee has no obligation to notify any party
of any pending sale or any action or proceeding unless held or commenced and
maintained by Trustee under this Deed of Trust. Trustor shall pay to Trustee
reasonable compensation and reimbursement for services and expenses in the
administration of the trusts created hereunder, including reasonable attorneys'
fees. Trustor hereby agrees to indemnify Trustee and Beneficiary against all
losses, claims, demands and liability which either may incur, suffer or sustain
in the execution of the trust or trusts created hereunder or in the performance
of any act required or permitted hereunder or by law.

      5.17  Substitution of Trustees. From time to time, by a writing signed and
acknowledged by Beneficiary and recorded in the Office of the Recorder of the
County in which the Subject Property is situated, Beneficiary may appoint
another trustee to act in the place and stead of Trustee or any successor. Such
writing shall refer to this Deed of Trust and set forth the date, book and page
of its recordation. The recordation of such instrument of substitution shall
discharge Trustee herein named and shall appoint the new trustee as the trustee
hereunder with the same effect as if originally named Trustee herein. A writing
recorded pursuant to the provisions of this paragraph shall be conclusive proof
of the proper substitution of such new trustee.

      5.18  Acceleration Upon Sale or Encumbrance. That the financial stability
and managerial and operational ability of Trustor are a substantial and material
consideration to Beneficiary in its agreement to enter into the transaction
evidenced by this Deed of Trust and the Participation Agreement is hereby
acknowledged by Trustor and Beneficiary. That the transfer or further
encumbrance of the Subject Property, could significantly and materially alter,
impair and reduce Beneficiary's security for the Participation Agreement is
likewise acknowledged by

                                      -13-
<PAGE>
Trustor and Beneficiary. In order, therefore, to induce Beneficiary to accept
the Participation Agreement, except with respect to a transfer which is included
in items (i) and (ii) of the definition of "Authorized Transfer," in Section 3.7
of the Participation Agreement (a "Permitted Transfer"), Trustor agrees not to
transfer or further encumber the Subject Property, or any portion thereof, or
any interest therein, without the prior written consent of Beneficiary. In the
event Trustor, or any successor in interest of Trustor, shall transfer or
further encumber the Subject Property or any portion thereof, or any interest
therein, other than by a Permitted Transfer, without first obtaining the written
consent of Beneficiary, all indebtedness secured by this Deed of Trust,
including without limitation the amount due under the Participation Agreement,
shall, at the option of Beneficiary and without notice or demand, become
immediately due and payable. As used herein, "transfer" includes the sale,
option to sell, transfer or conveyance of the Subject Property, or any portion
thereof, or any interest therein, or the transfer of any general partnership
interests, membership interests or shares of stock (as applicable) in Trustor,
whether voluntary, involuntary (except by eminent domain or upon death or mental
incapacity), by operation of law or otherwise, except that the transfer of
outstanding capital stock or other listed equity interests through the
"over-the-counter" market or any recognized national or international securities
exchange, shall not be included in determining whether Subject Property has been
transferred.

      5.19  Intentionally Left Blank.

      5.20  Reconveyance. Upon Beneficiary's written request, and upon surrender
to Trustee for cancellation of this Deed of Trust and any note, instrument or
instruments setting forth all obligations secured hereby, Trustee shall
reconvey, without warranty, the Subject Property or that portion thereof then
held hereunder. The recitals of any matters or facts in any reconveyance
executed hereunder shall be conclusive proof of the truthfulness thereof. To the
extent permitted by law, the reconveyance may describe the grantee as "the
person or persons legally entitled thereto." Neither Beneficiary nor Trustee
shall have any duty to determine the right of persons claiming to be rightful
grantees of any reconveyance. When the Subject Property has been fully
reconveyed, the last such reconveyance shall operate as a reassignment of all
future rents, issues and profits of the Subject Property to the person or
persons legally entitled thereto, unless such reconveyance expressly provides to
the contrary.

                                       VI.

                               DEFAULT PROVISIONS

      The following shall constitute events of default ("Events of Default")
hereunder:

      6.01  Payment. Failure of Trustor to make any payment required under this
Deed of Trust or the Participation Agreement when and as it becomes due and
payable.

      6.02  Breach of General Covenants. A default by Trustor in the due, prompt
and complete observance and performance of each and every material obligation,
covenant and agreement in the Participation Agreement or in this Deed of Trust,
other than a default specified in paragraph 6.01 above and the continuation of
the default for a period of thirty (30) days after Trustor's receipt of written
notice by Beneficiary describing the defect in reasonable detail and

                                      -14-
<PAGE>
demanding its cure, however, if the default is of a type which, for reasons
other than reasons within the reasonable control of Trustor, is not susceptible
of cure within such thirty (30) day period, but is susceptible of cure within a
reasonable period of time, then no Event of Default shall occur under this
paragraph unless Trustor shall fail to commence to cure such default within
thirty (30) day period or shall fail to diligently pursue the cure of such
default to completion within a reasonable period of time thereafter.

      6.03  Intentionally Omitted.

      6.04  Appointment of Receiver. The appointment, pursuant to an order of a
court of competent jurisdiction, of a trustee, receiver or liquidator of the
Subject Property or any part thereof, or of Trustor, unless such appointment is
discharged within ninety (90) days after the date of filing thereof.

      6.05  Bankruptcy Filing By Trustor. The filing by Trustor of a petition in
bankruptcy or for an arrangement or for reorganization pursuant to the Federal
Bankruptcy Code or any similar law, federal or state, or the adjudication of
Trustor as a bankrupt or as insolvent by a decree of a court of competent
jurisdiction, or the making of an assignment for the benefit of creditors, or
the admission by Trustor in writing of its inability to pay its debts generally
as they become due, or the giving of consent by Trustor to the appointment of a
receiver or receivers of all or any part of its property, unless such bankruptcy
filing is discharged within ninety (90) days after the date of filing thereof.

      6.06  Bankruptcy Filing by Creditors. The filing by any of the creditors
of Trustor or the reorganization of Trustor pursuant to the Federal Bankruptcy
Code or any similar law, federal or state and the same is not discharged within
ninety (90) days after the date of filing thereof.

      6.07  Default Under First Deed of Trust. The giving of notice or
declaration of default or the occurrence of any default under the First Deed of
Trust or any of the documents related thereto which default is not cured within
thirty (30) days after the date of such notice or occurrence.

      6.08  Intentionally Omitted.

      6.09  Rights and Remedies. At any time after the occurrence of an Event of
Default hereunder, Beneficiary and/or Trustee shall have the following rights
and remedies, all of which are in addition to any rights and remedies available
to Beneficiary under the Participation Agreement or this Deed of Trust:

      (a)   With or without notice, to declare all obligations secured hereby
      immediately due and payable;

      (b)   With or without notice, and without releasing Trustor from any
      obligation hereunder, to cure any default of Trustor and, in connection
      therewith, to enter upon the Subject Property and to do such acts and
      things as Beneficiary or Trustee deem necessary or desirable to protect
      the security hereof, including, but without limitation, to appear in and
      defend any action or proceeding purporting to affect

                                      -15-
<PAGE>
      the security hereof or the rights or powers of Beneficiary or Trustee
      hereunder; to pay, purchase, contest or compromise any encumbrance,
      charge, lien or claim of lien which, in the judgment of either Beneficiary
      or Trustee is prior or superior hereto, the judgment of Beneficiary or
      Trustee being conclusive as between the parties hereto; to pay any
      premiums or charges with respect to insurance required to be carried
      hereunder; and to employ counsel, accountants, contractors and other
      appropriate persons to assist them;

      (c)   To commence and maintain an action or actions in any court of
      competent jurisdiction to foreclose this instrument as a mortgage or to
      obtain specific enforcement of the covenants of Trustor hereunder, and
      Trustor agrees that such covenants shall be specifically enforceable by
      injunction or any other appropriate equitable remedy and that for the
      purposes of any suit brought under this subparagraph, Trustor waives the
      defense of laches and any applicable statute of limitations;

      (d)   To enter upon, possess, manage and operate the Subject Property or
      any part thereof; to make, terminate, enforce or modify leases of the
      Subject Property upon such terms and conditions as Beneficiary deems
      proper; to make repairs, alterations and improvements to the Subject
      Property necessary, in Trustee's or Beneficiary's judgment, to protect or
      enhance the security hereof. All sums realized by Beneficiary under this
      subparagraph, less all costs and expenses incurred by it under this
      subparagraph, including reasonable attorneys' fees, and less such sums as
      Beneficiary deems appropriate as a reserve to meet future expenses under
      this subparagraph, shall be applied on any indebtedness secured hereby in
      such order as Beneficiary shall determine. Neither application of said
      sums to said indebtedness nor any other action taken by Beneficiary under
      this subparagraph shall cure or waive any default or notice of default
      hereunder or nullify the effect of any such notice of default. Beneficiary
      or Trustee, or any employee or agents of Beneficiary or Trustee, or a
      receiver appointed by a court may take any action or proceeding authorized
      hereunder or by law without regard to (i) the adequacy of the security for
      the indebtedness secured hereunder, (ii) the existence of a declaration
      that the indebtedness secured hereby has been declared immediately due and
      payable, or (iii) the filing of a notice of default;

      (e)   To execute a written notice of such default and of its election to
      cause the Subject Property to be sold to satisfy the obligations secured
      hereby. Trustee shall give and record such notice as the law then requires
      as a condition precedent to a Trustee's sale. When the minimum period of
      time required by law after such notice has elapsed, Trustee, without
      notice to or demand upon Trustor except as otherwise required by law,
      shall sell the Subject Property at the time and place of sale fixed by it
      in the notice of sale, either as a whole or in separate parcels and in
      such order as it or Beneficiary may determine, at public auction to the
      highest bidder for cash, in lawful money of the United States, payable at
      time of sale (the obligations hereby secured being the equivalent of cash
      for purposes of said sale). Trustor shall have no right to direct the
      order in which the Subject Property is sold. Trustee may if so instructed
      by Beneficiary postpone sale of all or any portion of the Subject Property
      by public announcement at such time and place of sale, and from time to
      time thereafter may postpone such sale by public announcement at such time
      fixed by the preceding postponement. Trustee shall deliver to the
      purchaser at such sale a deed conveying the Subject Property or portion
      thereof so sold, but without any covenant or warranty, express or implied.
      The recitals in such deed of any matters or facts shall be conclusive
      proof of the truthfulness thereof. Trustor or Beneficiary, but not
      Trustee, may purchase at

                                      -16-
<PAGE>
      such sale.

      After deducting all costs, fees and expenses of Trustee and of this trust,
      including cost of evidence of title and reasonable attorneys' fees in
      connection with the sale, Trustee shall apply the proceeds of sale to
      payment of (i) all sums so expended under the terms hereof not then
      repaid, with accrued interest at the Default Rate; (ii) the payment of all
      other sums then secured hereby in such order as Beneficiary may direct;
      and (iii) the remainder, if any, to the person or persons legally entitled
      thereto;

      (f)   To resort to and realize upon or waive the security hereunder and
      any other security now or hereafter held by Beneficiary in such order and
      manner as Trustee and Beneficiary or either of them may, in their sole
      discretion determine; resort to any or all such security may be taken
      concurrently or successively and in one or several consolidated or
      independent judicial actions or lawfully taken non-judicial proceedings,
      or both;

      (g)   With respect to all or any part of the encumbered Property that
      constitutes personalty, Beneficiary shall also have all of the rights and
      remedies of a secured party under the Commercial Code in effect in the
      State of California; and

      (h)   If this Deed of Trust is foreclosed by judicial action, Beneficiary
      will be entitled to a judgment which will provide that if the foreclosure
      sale proceeds are insufficient to satisfy the judgment, execution may
      issue for any amount by which the unpaid balance of the obligations
      secured by this Deed of Trust exceeds the net sale proceeds payable to
      Beneficiary. Such judgment will be enforceable against Trustor.

      6.10  Receiver. In addition to the foregoing rights and remedies,
Beneficiary shall upon the occurrence of an Event of Default be entitled to the
appointment of a receiver as a matter of right without regard to whether the
apparent value of the Subject Property exceeds the amount of the secured
indebtedness, and any receiver appointed may serve without bond.

      6.11  Payment of Costs, Expenses and Attorneys' Fees. All costs and
expenses incurred by Trustee and Beneficiary pursuant to subparagraphs (a)
through (h), inclusive, of Paragraph 6.09 and Paragraph 6.10 (including, but
without limitation, court costs and attorneys' fees, whether incurred in
litigation or not) shall be payable by Trustor and shall bear interest at a rate
per annum equal to the Default Rate from the date of expenditure until said sums
have been paid. Beneficiary shall be entitled to bid, at the sale of the Subject
Property held pursuant to Paragraph 6.09 above, the amount of said costs,
expenses and interest in addition to the amount of the other obligations hereby
secured as a credit bid, the equivalent of cash.

      6.12  Remedies Cumulative.  All rights and remedies of Beneficiary and
Trustee hereunder are cumulative and in addition to all rights and remedies
provided by law.

      6.13  Releases, Extensions, Modification and Additional Security.
Beneficiary may, without affecting the liability of any person for payment of
any indebtedness secured hereby, make any agreement or take any action extending
the maturity or otherwise altering the terms or increasing the amount of any
indebtedness secured hereby, and accept additional security or

                                      -17-
<PAGE>
release all or a portion of the Subject Property and/or other security held to
secure the indebtedness secured hereby.

      6.14  Failure of Trustor to Comply With Deed of Trust. Should Trustor fail
to make any payment or do any act required by this Deed of Trust, or should
there be any action or proceeding (including, without limitation, any judicial
or nonjudicial proceeding to foreclose the lien of a junior or senior mortgage
or deed of trust) affecting or purporting to affect the Subject Property, this
Deed of Trust, Beneficiary's security for the performance of Trustor's
obligations under the Participation Agreement, or the rights or powers of
Beneficiary or Trustee under the Participation Agreement or this Deed of Trust,
Beneficiary or Trustee may (but are not obligated to): (a) make any such payment
or do any such act in such manner and to such extent as either deems necessary
to preserve or protect the Subject Property, this Deed of Trust, or
Beneficiary's security for the performance of Trustor's obligations under the
Participation Agreement, Beneficiary being authorized to enter upon the Subject
Property for any such purpose; and (b) in exercising any such power, pay
necessary expenses, employ attorneys and pay reasonable attorneys' fees incurred
in connection with the exercise of such power without notice to or demand upon
Trustor and without releasing Trustor from any obligation under this Deed of
Trust.

                                      VII.

                            MISCELLANEOUS PROVISIONS

      7.01  Non-Waiver. By accepting payment of any sum secured hereby after its
due date or late performance of any obligation secured hereby, Beneficiary shall
not waive its right against any person obligated directly or indirectly
hereunder or on any obligation hereby secured or to declare default for failure
to make such prompt payment. No exercise of any right or remedy by Beneficiary
or Trustee hereunder shall constitute a waiver of any other right or remedy
herein contained or provided by law.

      7.02  Execution of Documents. Trustor agrees, upon demand by Beneficiary
or Trustee, to execute any and all documents and instruments required to
effectuate the provisions hereof.

      7.03  Statements of Conditions. From time to time as required by law,
Beneficiary shall furnish to Trustor such statement as may be required
concerning the condition of the obligations secured hereby. Beneficiary shall be
entitled to the payment of a fee, not to exceed the maximum fee allowed by law,
for any such statement.

      7.04  Obligations of Trustor, Joint and Several. If more than one person
has executed this Deed of Trust as Trustor, the obligations of all such persons
hereunder shall be joint and several.

      7.05  Beneficiary Defined. The word "Beneficiary" hereunder means the
beneficiary named herein or any future owner or holder, including pledgee, of
any note, notes or instrument secured hereby.

                                      -18-
<PAGE>
      7.06  Rules of Construction. When the identity of the parties hereto or
other circumstances make it appropriate, the masculine gender includes the
feminine and/or neuter, and the singular number includes the plural. Specific
enumeration of rights, power and remedies of Trustee and Beneficiary and of acts
which they may do and of acts Trustor must do and acts Trustor must not do shall
not exclude or limit the general. The headings of each paragraph are for
information and convenience and do not limit or construe the contents of any
provision hereof.

      7.07  Severability. If any term of this Deed of Trust, or the application
thereof to any person or circumstances, shall, to any extent, be invalid or
unenforceable, the remainder of this Deed of Trust, or the application of such

                                    PURCHASE

      1.    Purchase Price; Escrow Opening. Seller agrees to sell to Buyer, and
Buyer agrees to purchase from Seller, the Property for the sum of the Purchase
Price, which shall be paid as set forth below in this Section 1.

            1.1   Deposit. Concurrent with the delivery to the Escrow Holder of
this Agreement, executed by Buyer, Buyer shall deliver to Escrow Holder the
Deposit which Escrow Holder shall invest in a federally-insured, interest
bearing account. All interest which accrues on the Deposit shall be deemed a
part of the Deposit, and credited to Buyer's account and shall be credited to
payment of the Purchase Price or paid to the party entitled thereto pursuant to
this Agreement. The Deposit shall remain fully refundable to Buyer during the
period commencing on the Agreement Date and ending at 5:00 pm (Pacific Time) on
the Approval Date (the "Contingency Period"). Thereafter, the Deposit shall not
be refunded to Buyer unless the transaction contemplated by this Agreement is
not consummated as the result of Seller' default under the terms of this
Agreement or the failure of a condition precedent to Buyer's obligations as set
forth in Section 2 of this Agreement. The Deposit and all interest earned
thereon shall be credited toward the payment of the Purchase Price at Closing.
Notwithstanding the foregoing, in lieu of making the Deposit, Buyer shall have
the right to cause the entity that, as of the Agreement Date, is the holder of
the "Note", as that term is defined in the Lease Termination Agreement, to
deliver to Seller such holder's written agreement that, upon a default by Buyer
under this Agreement which would otherwise entitle Seller to receive the Deposit
pursuant to the terms of Section 13.2, below, the principal balance of such Note
shall be reduced by the amount of $1,125,000.00. In such event, Buyer shall have
no obligation to deliver the Deposit to Escrow Holder.

      1.2   Purchase Price Balance. Provided that this Agreement has not
previously terminated, not later than one (1) Business Day prior to the Closing
Date, Buyer shall deliver the balance of the Purchase Price, together with
Buyer's share of costs, expenses and prorations, to Escrow Holder by wire
transfer of immediately available funds.

      1.3   Escrow Opening. Buyer and Seller shall promptly cause the opening of
"Escrow" by delivering a fully executed copy of this Agreement to Escrow Holder
and this instrument shall serve as the instructions to Escrow Holder for
consummation of the purchase and sale contemplated hereby. Seller and Buyer
agree to execute such additional and supplementary escrow instructions as may be
appropriate to enable the Escrow Holder to comply with the terms of this
Agreement; provided, however, that in the event of any conflict between the
provisions of this Agreement and any supplementary escrow instructions, the
terms of this Agreement shall control, and this instrument shall serve as the
instructions to Escrow Holder for consummation of the purchase and sale
contemplated

                                      -3-
<PAGE>
hereby. "Escrow" means the escrow opened with Escrow Holder for the consummation
of the transaction described in this Agreement, which shall open by the delivery
of a fully executed original of this Agreement to Escrow Holder together with
the Deposit.

      2.    Contingency Period.

            2.1   Property Inspections and Investigations. During the
Contingency Period, Buyer shall have the right subject to the terms set forth
herein to enter the Property, make such investigations and surveys as Buyer
reasonably determines to be appropriate in connection with its determination of
whether or not the Put Conditions have been satisfied.

                  2.1.1 Insurance. After Buyer has provided to Seller a
certificate of insurance(s) evidencing Buyer's or Buyer's agents', consultants'
and/or contractors' (as the case may be) procurement of a commercial general
liability insurance policy as required herein, Seller shall permit Buyer and its
authorized agents, consultants and contractors to enter upon the Property during
reasonable business hours (provided that Buyer shall not unreasonably interfere
with or disturb any tenants' operations therein or Seller's operation of the
Property) to make and perform such environmental evaluations, and other
inspections and investigations of the physical condition of the Property, as
Buyer reasonably deems appropriate. Buyer shall maintain, and shall ensure that
its agents, consultants and contractors maintain, public liability and property
damage insurance insuring against any liability arising out of any entry, tests
or investigations of the Property pursuant to the provisions hereof. Such
insurance maintained by Buyer and/or its consultants, agents and contractors (as
applicable) shall be in the amount of Two Million Dollars ($2,000,000.00)
combined single limit for injury to or death of one or more persons in an
occurrence, and for damage to tangible property (including loss of use) in an
occurrence. The policy maintained by Buyer shall insure the contractual
liability of Buyer covering the indemnities herein and shall (i) name the Seller
and its manager (and their successors, assigns and affiliates) as additional
insureds, (ii) contain a cross-liability provision, and (iii) contain a
provision that "the insurance provided by Buyer hereunder shall be primary and
non-contributing with any other insurance available to Seller." Buyer shall
provide Seller with evidence of such insurance coverage prior to any entry,
tests or investigations of the Property. The aforementioned insurance coverage
may be obtained under a blanket policy carried by Buyer or its agents,
consultants or contractors, as the case may be.

                  2.1.2 Intrusive or Destructive Testing. Notwithstanding the
foregoing, Buyer shall not be permitted to undertake any intrusive or
destructive testing of the Property, including without limitation a "Phase II"
environmental assessment, without in each instance first obtaining Seller's
written consent as to the manner and timing thereof, which consent shall not be
unreasonably withheld. Prior to entering the Property, and prior to any entry to
perform any necessary on-site inspections, tests or investigations, (and on each
and every occasion), Buyer shall (i) deliver to Seller prior written notice
thereof [or verbal notice wherein Buyer actually speaks with a representative of
Seller (not a voicemail message) with written notice delivered immediately
thereafter, if requested at such time], (ii) inform Buyer of the identity of the
company or party(s) who will perform such inspections, tests or investigations
and the proposed scope of the inspections, tests or investigations, and (iii)
shall afford Seller a reasonable opportunity to have a representative of Seller
present to accompany Buyer while Buyer or such third-party company performs its
evaluations, inspections, tests and other investigations of the physical
condition of the Property. Seller shall approve or disapprove any proposed
inspections, tests or investigations and the party(s) performing the same within
two (2) business days after receipt of such notice. Seller's failure to advise
Buyer of its disapproval of any proposed inspections, tests or investigations
and the party(s) performing the same within such two (2) business day period
shall be deemed Seller's approval thereof, except to the extent said proposed
inspections, tests or investigations relate to "Phase II" environmental matters,
in which event Seller's failure to advise Buyer of its approval or disapproval
of any proposed environmental inspections, tests or investigations and the
party(s) performing the same within such two (2)

                                      -4-
<PAGE>
business day period shall be deemed Seller's disapproval thereof. Upon request,
Buyer shall promptly deliver to Seller copies of any reports relating to any
inspections, tests or investigations of the Property performed by or on behalf
of Buyer. Prior to Buyer contacting the tenants, Buyer shall give Seller written
notice thereof, including the identity of the company or persons who will
perform any tenant interview or contacts. Seller or its representative(s) may be
present at any such interview or meeting with the tenants and Buyer will
reasonably cooperate and coordinate with Seller to effectuate same. The term
"Hazardous Materials" as used in this Agreement shall mean and refer to (a) any
hazardous or toxic wastes, materials or substances, or chemicals, and other
pollutants or contaminants, which are or become regulated by applicable local,
state, regional and/or federal orders, ordinances, statutes, rules, regulations
(as interpreted by judicial and administrative decisions) and laws; (b)
asbestos, asbestos-containing materials or urea formaldehyde; (c)
polychlorinated biphenyls; (d) flammables, explosive, corrosive or radioactive
materials; (e) medical waste and biochemicals; and (f) gasoline, diesel,
petroleum or petroleum by-products.

                  2.1.3 Investigations Indemnity. Buyer shall keep the Property
free from all liens and shall indemnify, defend (with counsel reasonably
satisfactory to Seller), protect, and hold Seller and each of the parties
comprising Seller and each of their members, partners, officers, trustees,
employees, representatives, agents, lenders, related and affiliated entities,
successors and assigns harmless from and against any and all claims, demands,
liabilities, judgments, penalties, losses, costs, damages, and expenses
(including, without limitation, attorneys' and experts' fees and costs) relating
to or arising in any manner whatsoever from any studies, evaluations,
inspections, investigations or tests made by Buyer or Buyer's agents or
representatives relating to or in connection with the Property or entries by
Buyer or its agents or representatives in, on or about the Property; provided,
Buyer shall not be liable to Seller under the foregoing indemnity solely as a
result of the discovery by Buyer of a pre-existing condition in or on the
Property. Notwithstanding any provision to the contrary in this Agreement, the
indemnity obligations of Buyer under this Agreement shall survive any
termination of this Agreement or the delivery of the Grant Deed and the transfer
of title. In addition to the foregoing indemnity, if there is any damage to the
Property caused by Buyer's and/or its agents' or representatives' entry in or on
the Property, Buyer shall immediately restore the Property substantially to the
same condition existing prior to Buyer's and its agents' or representatives'
entry in, on or about the Property.

                  2.1.4 Contracts. If and to the extent not previously delivered
under the Participation Agreement, within five (5) days after the Agreement
Date, but only to the extent the same is actually in Seller's or its property
manager's possession or under their immediate control, Seller will deliver to
Buyer a copy of all service agreements, commission agreements, maintenance
agreements, easement agreements, improvement agreements, license agreements, and
other agreements related to or affecting the Property and not included as part
of the title documents delivered pursuant to Section 4.1.1 hereof (collectively,
the "Contracts"). Buyer shall have until 5:00 p.m. (Pacific Time) on the date
which is five (5) business days prior to the Approval Date to notify Seller in
writing, specifying any Contracts which Buyer desires be left in place following
the Closing(collectively, the "Approved Contracts") which Approved Contracts
shall be assigned by Seller to Buyer at the Closing. All Contracts other than
the Approved Contracts (the "Disapproved Contracts") shall be terminated by
Seller as of the Closing. Seller shall assign its rights and interests under the
Approved Contracts to Buyer at the Closing pursuant to the General Assignment in
substantially the form attached hereto as Exhibit "G". Failure by Seller
terminate some or all of the Disapproved Contracts on or before the Closing
shall be deemed to be a failure of this condition.

                  2.1.5 Diligence Documents. Within five (5) days after the
Agreement Date, Seller will deliver to Buyer or otherwise make available to
Buyer at Seller's offices during normal business hours for inspection by Buyer,
a true and complete copy of the following (collectively, the "Diligence
Documents") (a) the title report and copies of all title exceptions as more
particularly described in Section 2.1.6, (b) without any warranty or
representation as to the accuracy thereof or to the ability of Buyer to rely
thereon, a copy of any existing survey(s) of the Property, (c) current Phase I
and Phase II environmental

                                      -5-
<PAGE>
reports prepared with respect to the Property and delivered by a contractor
reasonably approved by Buyer and with a reliance letter to the benefit of Buyer,
(d) complete copies of all leases encumbering the Property, together with all
amendments and modification thereto, and the tenant estoppel certificates
referred to in Section 2.2.5, and (e) copies of the most current operating
statement, tax bills, rent roll and the general ledger for the Property. Buyer
shall have until 5:00 p.m. (Pacific Time) on the Approval Date to notify Seller
in writing of its approval of such matters as set forth in Section 2.2, below.

                  2.1.6 Title Review. If not already delivered prior to the
Agreement Date, within five (5) days after the Agreement Date, Seller will cause
to be issued and delivered to Buyer a preliminary title report for the Property,
together with all documents evidencing exceptions to title referred to therein
issued by the Title Company (collectively, the "Title Report"). Any exceptions
shown on the Title Report which were not listed on Exhibit H to the Lease
Termination Agreement are referred to herein as the "New Exceptions". Buyer
shall have until 5:00 p.m. (Pacific Time) on the date which is fifteen (15)
business days prior to the Approval Date to either approve or disapprove of any
New Exceptions, or to notify Seller in writing, specifying those New Exceptions
to which Buyer objects ("Title Objection Notice"). Seller shall have a period of
three (3) business days after Seller's receipt of the Title Objection Notice (a)
to remove, or agree to remove prior to the Closing, some or all of those New
Exceptions to which Buyer has objected in the Title Objection Notice, and to
inform Buyer of the same, or (b) to advise Buyer, in writing, that Seller will
not agree to remove some or all of the New Exceptions to which Buyer has
objected in the Title Objection Notice; the foregoing election by Seller being
at Seller's sole option and discretion ("Title Response Notice"). If Seller
fails to timely deliver to Buyer the Title Response Notice, it shall be
conclusively deemed that Seller has elected not to remove any of those New
Exceptions to which Buyer has objected as specified in the Title Objection
Notice. If Seller advises Buyer in its Title Response Notice that it will not
remove or agree to remove some or all of those New Exceptions to which Buyer has
objected in the Title Objection Notice (or Seller is deemed to have so advised
Buyer), then Buyer shall have until 5:00 p.m. (Pacific Time) on the Approval
Date to advise Seller, in writing, whether Buyer elects to waive such objections
and proceed with the acquisition of the Property or to terminate this Agreement.
Failure by Seller to remove or failure of Seller to inform Buyer that Seller has
or has not removed those specified New Exceptions which Seller has expressly
agreed to remove in the Title Response Notice on or before the business day
prior to the Closing Date shall be deemed to be a failure of this condition, in
which event the Agreement shall terminate, the Deposit shall be returned to
Buyer, and the parties shall have no further obligations hereunder except for
Buyer's surviving obligations and Seller's surviving obligations, unless Buyer
withdraws its objections in writing. Notwithstanding the foregoing, on or prior
to Closing Seller shall remove or cause to be removed those certain monetary
liens or encumbrances affecting the Property which Seller has created or
expressly permitted to exist other than current taxes and assessments.

                  2.1.7 Space Certificate. No later than five (5) business days
prior to the Approval Date, Seller shall provide Buyer with a written
certification delivered by a licensed architect approved by Buyer, certifying
that the combined rentable square footage of the 4000 and 4100 Third Avenue
buildings (as determined in accordance with the Standard Method for Measuring
Floor Area in Office Buildings published by the Building Owners and Mangers
Association International (ANSI-Z65.1-1996) is 260,000 square feet or greater
(the "Space Certificate"). In the event that the Space Certificate shows
combined rentable square footage which is less than 260,000 square feet (the
"Certified Square Footage"), the Purchase Price shall be reduced by the
percentage by which the Certified Square Footage is less than 260,000.

            2.2   Put Conditions. Buyer's inspections of the Property as set
forth in Section 2.1, above, shall be for the purpose of determining whether or
not the Property meets the following conditions (the "Put Conditions").

                                      -6-
<PAGE>
                  2.2.1 Title and Survey. There are no New Exceptions
disapproved by Buyer in accordance with the terms of Section 2.1.6, above, which
Seller has not agreed to remove prior to the Closing Date.

                  2.2.2 Physical Property Conditions. There shall have been no
material changes in the physical condition of the Property, normal wear and tear
excepted, from the condition in which it existed as of the date of the
Participation Agreement, as such condition may be evidenced by documents and
materials provided directly to Richard Berk, a representative of Buyer, prior to
the date of the Participation Agreement, except as allowed pursuant to the terms
of Section 12, below.

                  2.2.3 Environmental Conditions. The environmental condition of
the Property shall not be materially different from the condition set forth in
that certain Phase I Environmental Site Assessment for East 3rd Avenue Property,
Foster City, California, prepared for Inktomi, Inc. by Romig Engineers, Inc.,
dated July, 2000, which report was delivered to Buyer prior to the date of the
Participation Agreement.

to (i) that certain Lease Agreement between PE Corporation (NY) (then named The
Perkin-Elmer Corporation) and WHFST Real Estate Limited Partnership (predecessor
in interest to Seller), dated as of December 10, 1998, as amended by that
certain First Amendment to Lease Agreement dated as of August 16, 1999, and (ii)
that certain Office Lease between Lincoln Property Company N.C., Inc., and WHFST

2000 (items (i) and (ii), collectively, the "Leases", and the current tenants
under such Leases, collectively, the "Tenants"), which modifications have not
been approved in advance by Buyer, which approval shall not be unreasonably
withheld, conditioned or delayed. Buyer hereby approves the terms of the second
amendment to the Lease by PE Corporation (NY), in the form which was delivered
to Anton N. Natsis by Sherry Geyer under cover of e-mail, on or about September
5, 2002, and, provided there has been no material change to such proposed
amendment from such form.

                  2.2.5 Tenant Estoppels. Seller shall have delivered estoppel
certificates from each of the Tenants, dated during the Contingency Period, for
the Leases in substantially the same form as the form estoppel attached to each
Tenant's Lease, with no exceptions shown thereon, and with no assertions therein
of any default by Seller under the relevant Tenant's Lease.

                  2.2.6 Seller Financial Condition. There shall have been no
general assignment by Seller for the benefit of creditors, or the taking of any
corporate action in furtherance of bankruptcy or dissolution whether or not
there exists any proceeding under an insolvency or bankruptcy law, or the filing
by or against Seller of any proceeding under an insolvency or bankruptcy law, or
any execution or other judicially authorized seizure of any of Seller's assets.

            2.3   Approval or Disapproval of Put Conditions. In the event that
during the Contingency Period, Buyer determines that any of the Put Conditions
are not met, Buyer shall have the right on or before 5:00 p.m. (Pacific Time) to
deliver notice to Seller of such failure (the "Failure of Condition Notice").
Any Failure of Condition Notice shall specify with reasonable particularity
which of the Put Conditions are unsatisfied and the curative action by Seller,
if any, needed to satisfy the particular Put Conditions(s). If Buyer approves or
otherwise waives in writing all of the Put Conditions (the

                                      -7-
<PAGE>
"Approval Notice"), by timely delivering to Seller the Approval Notice, the
parties shall proceed with this transaction and the Closing. Failure by Buyer to
notify Seller of its approval or disapproval the Put Condition within the
specified time period set forth herein, shall be deemed an approval by Buyer of
all such matters, in which event such the Put Conditions shall be conclusively
deemed to be satisfied and approved. If Buyer delivers to Seller the Approval
Notice prior to 5:00 p.m. (Pacific Time) on the Approval Date or if the Put
Conditions are deemed approved pursuant to this Section 2.2.1, the Deposit shall
become non-refundable to Buyer.

            2.4   Seller Cure; Conditions Notice. Seller shall have three (3)
business days after Buyer has delivered to Seller the Buyer's Failure of
Condition Notice to notify Buyer in writing of Seller's election either to (a)
take such actions as may be necessary to cure such matters to Buyer's reasonable
satisfaction prior to the date of Closing, or (b) advise Buyer that Seller will
not cure such matters (the "Seller's Conditions Notice"). If Seller elects not
to cure such matters, then within two (2) business days after Buyer's receipt of
the Seller's Conditions Notice, Buyer, at its sole option, may elect to do any
of the following: (1) Buyer may elect to terminate this Agreement by delivering
written notice thereof to Seller, in which event Seller shall promptly cause the
return to Buyer of the Deposit, and the parties shall have no further
obligations hereunder except for Buyer's surviving obligations and Seller's
surviving obligations; (2) Buyer may elect to waive such Put Condition and
proceed to Closing. If Seller elects to cure such matters as set forth in the
Failure of Condition Notice, Seller shall promptly take any and all actions as
may be necessary to cure same and the date of the Closing may be extended for a
period of time reasonably acceptable to both Seller and Buyer, not to exceed
thirty (30) days, to enable Seller to accomplish same.

      3.    Closing Conditions.

attributable to the period following the Closing shall either be paid to Buyer
at the Closing or credited against the Purchase Price, at Seller's option. Any
common area maintenance expenses or other operating cost pass throughs payable
by the Tenants under the Leases on an estimated basis (collectively, the "Tenant
Charges") shall be reconciled against actual charges and expenses as of and at
the Closing, to the extent then possible, and Seller shall provide a proposed
reconciliation for Buyer's approval. Seller shall have a period of sixty (60)
days following the actual Closing Date to provide Buyer with a final
reconciliation of Tenant Charges. If the final reconciliation, as approved by
Buyer, shows that Seller owes Buyer additional sums, Seller shall deliver such
amount to Buyer together with the delivery of the final reconciliation of the
Tenant Charges. If the final reconciliation, as approved by Buyer, shows that
Buyer owes Seller additional sums, Buyer shall pay such amount to Seller within
ten (10) days after Buyer's receipt of the final reconciliation.

                                      -11-
<PAGE>
Other than as set forth above, there shall not be any further reconciliation of
such Tenant Charges after the final reconciliation thereof, the proration of
such Tenant Charges pursuant to the final reconciliation being conclusively
presumed to be accurate. After the final reconciliation of the Tenant Charges is
made by and between the parties, Buyer shall be solely liable and responsible to
the tenants for such reconciliation of Tenant Charges under the Leases. The
foregoing covenants made by the parties with respect to the final reconciliation
of the Tenant Charges shall survive the Closing.

            7.2   Rent Arrearages. Delinquent rent and Tenant Charges shall be
prorated between Buyer and Seller as of and through the Closing Date upon
receipt by Buyer. Buyer shall have the right, but not the obligation, to collect
any delinquent or other rental and reimbursable Tenant Charges and other expense
arrearages attributable to the period prior to the Closing, provided that Buyer
agrees to send invoices to Tenants for delinquent rent on a monthly basis for
three (3) months following the Closing Date. With respect to any rent or Tenant
Charges arrears arising under any of the Leases, Seller shall have the right to
attempt to collect such pre-closing delinquent rental obligations (including
without limitation, all Tenant Charges) and Buyer will cooperate with Seller in
such regard, at no cost to Buyer, provided that Buyer shall not be required to
declare a default against such tenants under such Leases for such pre-closing
delinquent rental obligations (including without limitation, all taxes and
Tenant Charges). Notwithstanding the foregoing, after the Closing Seller shall
not bring an action against any tenant under any of the Leases while such
tenants are tenants of any portion of the Property. After deduction of Buyer's
actual out-of-pocket costs of collection (including reasonable attorneys' fees)
Buyer shall promptly account to Seller and shall immediately reimburse Seller
for all delinquent rent and Tenant Charges received by Buyer and attributable to
the period prior to the Closing Date. Buyer shall remit any amounts to which
Seller is entitled in accordance with this Section 7.2 to Seller immediately
upon receipt. If either Buyer or Seller receives any revenues attributable to
the period during which it is not the owner of the Property, said party shall
promptly forward such amounts to the other party (if such revenues are only
partially attributable to the period during which said party is not the owner of
the Property, the amount paid to the other party shall be based upon proration
as of the Closing Date as set forth above). The provisions of this Section 7.2
shall survive the Closing.

            7.3   Property Taxes. To the extent not paid directly by any Tenants
of the Property or reimbursed by Tenants as part of Tenant Charges, all real
property taxes on the Property shall be prorated on an accrual basis so that
Seller pays all amounts that relate to the period prior to the Closing Date,
regardless of when such sums are billed, due or payable, and Buyer pays all
amounts relating to the period after the Closing Date.

            7.4   Utilities. Except to the extent payable by Tenants as part of
Tenant Charges, all utility charges and other expenses incurred in the ordinary
course of managing and operating the Property disclosed in the Operating
Statements and not covered elsewhere in this Section 7 shall be prorated on an
accrual basis as of the Closing Date.

            7.5   Leasing Commissions and Monetary Concessions. Seller shall pay
and perform all leasing commissions and other monetary and other concessions,
including improvement allowances and improvement work which relate to any Tenant
Leases, including any renewals, extensions or expansions related thereto,
executed or exercised, as applicable, before the Agreement Date, and Buyer shall
pay all leasing commissions and other monetary and other concessions, including
improvement allowances and improvement work, which relate to any Tenant Leases,
including any renewals, extensions or expansions related thereto, executed or
exercised, as applicable, from and after the Agreement Date, and, if applicable,
approved by Buyer pursuant to Section 11.5 below.

            7.6   Tenant Deposits. Buyer shall be credited with an amount equal
to all security deposits, prepaid rentals, cleaning fees and other deposits
which have not been previously applied by

                                      -12-
<PAGE>
Seller in accordance with any Lease, plus any interest accrued thereon, paid by
Tenants and received by Seller ("Tenant Deposits"). In addition, Seller shall,
at Seller's sole cost, take all actions required in order to transfer to Buyer
as of the Closing any letters of credit or other non-cash security held by
Seller under any Lease.

            7.7   Service Contracts.  Amounts payable under Approved
Contracts shall be prorated on an accrual basis as of the Closing Date.

      Except as set forth above, all prorations shall be made in accordance with
customary practice in San Mateo County. If and to the extent known and agreed
upon as of the Closing Date, prorations shall be paid by Buyer to Seller (if the
prorations result in a net credit to the Seller) or by Seller to Buyer (if the
prorations result in a net credit to the Buyer), by increasing or reducing the
cash to be paid by Buyer at the Closing Date. Any such prorations not determined
or not agreed upon as of the Closing Date shall be paid by Buyer to Seller, or
by Seller to Buyer, as the case may be, in cash as soon as practicable following
the Closing Date.

      8.    Disbursements and Other Actions by Escrow Holder and Seller.

            8.1   Escrow Holder's Disbursements and Other Actions. Upon the
Closing Date, Escrow Holder shall (A) deliver a completed PCOR to the "County
Recorder" and cause the Deed (with documentary transfer tax information to be
affixed after recording) and any other documents which the parties hereto may
mutually direct to be recorded in the Official Records of the County and obtain
conformed copies thereof for distribution to Buyer and Seller, (B) direct the
Title Company to issue the Title Policy to Buyer, (C) disburse the Purchase
Price, after adjustment pursuant to the terms of this Agreement for expenses and
prorations, to Seller and deliver the balance of the funds placed in escrow by
Buyer, if any, to Buyer, (D) disburse to Buyer a conformed copy of the Deed and
executed originals of the Tenant Lease Assignment, Assignment of Contracts, the
General Assignment, the FIRPTA Certificate, the Form 590, the Tenant
Notification Letters and change of address notices duly executed by Seller and
any other documents (or copies thereof) deposited into Escrow by Seller pursuant
hereto, and (E) disburse to Seller a conformed copy of the Deed and executed
originals of the Tenant Lease Assignment and the General Assignment.

      11.   Seller's Covenants Regarding Operation of the Property Through the
Closing Date. From and after the Execution Date, through and including the
Closing Date, Seller, at its sole cost and expense, shall:

            11.1  Keep all existing insurance policies affecting the Property
in full force and effect;

            11.2  Maintain the Property in such condition so that the Property
shall be in substantially the same condition on the Closing Date as on the
Agreement Date, reasonable wear and tear and the occurrence of any damage or
destruction to the Property by casualty or other causes or events beyond the
control of Seller excepted;

            11.3  Not extend, renew, modify or replace any of the Approved
Contracts without the prior written consent of Buyer, which consent (A) may not
be unreasonably withheld, conditioned or delayed by Buyer prior to the
expiration of the Contingency Period, (B) may be withheld in Buyer's sole
discretion following the expiration of the Contingency Period, and Seller shall
cancel all Disapproved Contracts as of the Closing Date;

            11.4  Not, without the prior written consent of Buyer, subject the
Property to any additional liens, encumbrances, covenants, conditions,
easements, rights of way after the date of this Agreement;

            11.5  Not make any alterations to the Property, except (a) to the

            11.6  Not modify, extend, terminate or otherwise change any material

affecting the Property without the prior written consent of Buyer, which consent
(A) may not be unreasonably withheld, conditioned or delayed by Buyer prior to
the expiration of the Contingency Period, (B) may be withheld in Buyer's sole
discretion following the expiration of the Contingency Period. In the event
Buyer has not responded to Seller's written request for consent within five (5)
business days after Seller's delivery to Buyer of all pertinent information
concerning such lease, obligation or agreement, Buyer shall be deemed to have
consented thereto;

            11.7  Not accept from any of the Tenants payment of rent more than
one month in advance (Seller shall be permitted to apply any security deposit to
rent or any other sum due from, or on account of any default by, any Tenant
subject to and in accordance with the terms of the applicable Tenant Lease); and

            11.8  Promptly notify Buyer of any material change in any condition
with respect to the Property or of any event or circumstance which makes any
representation or warranty of Seller under this Agreement untrue or misleading
in any material respect.

      12.   Condemnation, Damage and Destruction.

            12.1  Condemnation. If, prior to the Closing Date, any material
portion of the Real Property or any of the rentable square footage of the
Improvements is taken, by eminent domain or otherwise (or is the subject of a
pending, threatened or contemplated taking which has not been

                                      -17-
<PAGE>
consummated), or if the access thereto or available parking area therefor is
reduced or restricted so that in all cases (i) more than twenty-five percent
(25%) the Property as it is currently used is no longer usable or is not in
compliance with zoning requirements or (ii) Tenants occupying not less than
twenty-five percent (25%) can terminate their Tenant Leases, Seller shall
immediately notify Buyer, in writing, of such fact. In such event, Buyer shall
have the option, in its sole discretion, to terminate this Agreement upon
written notice to Seller given not later than ten (10) days after receipt of
Seller's notice. If Buyer does not exercise this option to terminate this
Agreement, neither party shall have the right to terminate this Agreement, but
the Seller shall assign and turn over, and the Buyer shall be entitled to
receive and keep, all awards for the taking by eminent domain which accrue to
Seller for periods after the Closing Date less the costs incurred by Seller to
repair and restore the Property and to make it into an architectural whole, if
Seller completes such repair or restoration prior to Closing, and the parties
shall proceed to consummate the transaction contemplated by this Agreement
pursuant to the terms hereof, without modification of the terms of this
Agreement and without any reduction in the Purchase Price. Unless this Agreement
is terminated, Seller shall take no action with respect to any eminent domain
proceeding without obtaining Buyer's prior written consent.

            12.2  Damage or Destruction. Prior to the Closing Date, and
notwithstanding the pendency of this Agreement, the entire risk of loss or
damage by earthquake, flood, landslide, fire or other casualty shall be borne
and assumed by Seller, except as otherwise provided in this Section. If, prior
to the Closing Date, any part of the Property is damaged or destroyed by
earthquake, flood, landslide, fire or other casualty, Seller shall immediately
notify Buyer, in writing, of such fact. If such damage or destruction is
"material", Buyer shall have the option to terminate this Agreement upon written
notice to the Seller given not later than ten (10) days after receipt of
Seller's notice. For purposes hereof, "material" shall be deemed to be (i) any
uninsured damage or destruction to the Property in excess of One Million and
No/100 Dollars ($1,000,000.00) or (ii) any insured damage or destruction (A)
where the cost of repair or replacement is estimated to be Two Million and
No/100 Dollars ($2,000,000.00) or more, or shall take more than one hundred
twenty (120) days to repair, in Buyer's good faith judgment, or (B) which would
allow any Tenant to terminate its Lease. If Buyer does not exercise this option
to terminate this Agreement, neither party shall have the right to terminate
this Agreement and Seller shall assign and turn over, and Buyer shall be
entitled to receive and keep, all insurance proceeds payable to it with respect
to such destruction (which shall then be repaired or not at Buyer's option and
cost), including any rent loss insurance applicable to periods after the Closing
Date, plus the Purchase Price shall be reduced by an amount equal to the
deductible amount with respect to the insurance and the parties shall proceed to
consummate the transaction contemplated by this Agreement pursuant to the terms
hereof without modification of the terms of this Agreement and without any
reduction in the Purchase Price. If Buyer does not elect to terminate this
Agreement by reason of any casualty, Buyer shall have the right to participate
in any adjustment of the insurance claim.

                               RIGHTS AND REMEDIES

      13.   Legal and Equitable Enforcement of this Agreement.

            13.1  Default by Seller. If the Close of Escrow and the consummation
of the transactions herein contemplated do not occur by reason of any default by
Seller, Buyer shall be entitled to terminate this Agreement and receive the
return of the Deposit, and/or to pursue any other remedy available to it at law
or in equity, including the specific performance of this Agreement, provided,
however, as a condition precedent to Buyer's right under this Section 13.1 to
obtain specific performance by Seller and to commence an action therefor and to
record a notice of lis pendens or other notice or filing in the county records,
Buyer shall have performed, or be in a position, ready, willing and able, as
required

                                      -18-
<PAGE>
by law, to fully perform, all of its obligations under this Agreement,
including, without limitation, delivery to Escrow Holder of the balance of the
Purchase Price (as adjusted) pursuant to Section 7. In no event may Buyer seek,
and Buyer hereby waives and releases Seller from any claim for any consequential
damages, if either the transfer of the Property does not occur or if the
transfer of the Property does occur pursuant to an action for specific
performance.

            13.2  DEFAULT BY BUYER. IF THE CLOSING AND THE CONSUMMATION OF THE
TRANSACTION HEREIN CONTEMPLATED DOES NOT OCCUR ON OR BEFORE THE CLOSING DATE AS
HEREIN PROVIDED BY REASON OF ANY DEFAULT OF BUYER, BUYER AND SELLER AGREE THAT
IT WOULD BE IMPRACTICAL AND EXTREMELY DIFFICULT TO ESTIMATE THE DAMAGES WHICH
SELLER MAY SUFFER. THEREFORE, BUYER AND SELLER HEREBY AGREE THAT A REASONABLE
ESTIMATE OF THE TOTAL DETRIMENT THAT SELLER WOULD SUFFER IN THE EVENT THAT BUYER

<PAGE>

            improvements owned by Landlord and serving the Building and the
            tenants thereof and the parcel(s) of land on which they are located.

II.   LEASE GRANT.

      Landlord leases the Premises to Tenant and Tenant leases the Premises from
Landlord, together with the right in common with others to use any portions of

foyers, restrooms, vending areas and lobby areas (the "Common Areas").

III.  POSSESSION.

      Landlord and Tenant acknowledge that Tenant is currently is possession of
the Premises and subject to Landlord's obligations under Section IX.B., Tenant
shall continue to accept the Premises in its "as is" condition and
configuration. Tenant agrees that the Premises are in good order and
satisfactory condition, and that there are no representations or warranties by
Landlord regarding the condition of the Premises or the Building, except as may
be expressly set forth in this Lease.

IV.   RENT.

      A.    Payments. As consideration for this Lease, Tenant shall pay
            Landlord, without any setoff or deduction (other than as expressly
            provided in this Lease), the Base Rent and Additional Rent due for
            the Term. "Additional Rent" means all sums (exclusive of Base Rent)
            that Tenant is required to pay Landlord. Additional Rent and Base
            Rent are sometimes collectively referred to as "Rent". Tenant shall
            pay and be liable for all rental, sales and use taxes (but excluding
            income taxes), if any, imposed upon or measured by Rent under
            applicable Law. Base Rent and recurring monthly charges of
            Additional Rent shall be due and payable in advance on the first day
            of each calendar month without notice or demand. All other items of
            Rent shall be due and payable by Tenant on or before 30 days after
            billing by Landlord. All payments of Rent shall be by good and
            sufficient check or by other means (such as automatic debit or
            electronic transfer) reasonably acceptable to Landlord. If Tenant
            fails to pay any item or installment of Rent when due, Tenant shall
            pay Landlord an administration fee equal to 4% of the past due Rent,
            provided that Tenant shall be entitled to a grace period of 5
            Business Days for the first 2 late payments of Rent in a given
            calendar year. If the Term commences on a day other than the first
            day of a calendar month or terminates on a day other than the last
            day of a calendar month, the monthly Base Rent and Tenant's Pro Rata
            Share of Expenses (defined in Section IV.C.) and Taxes (defined in
            Section IV.D.) for the month shall be prorated based on the number
            of days in such calendar month. Landlord's acceptance of less than
            the correct amount of Rent shall be considered a payment on account
            of the earliest Rent due. No endorsement or statement on a check or
            letter accompanying a check or payment shall be considered an accord
            and satisfaction, and either party may accept the

                                      -4-
<PAGE>

            check or payment without prejudice to that party's right to recover
            the balance or pursue other available remedies. Except as expressly
            set forth in this Lease, Tenant's covenant to pay Rent is
            independent of every other covenant in this Lease.

      B.    Payment of Tenant's Pro Rata Share of Expenses and Taxes. Tenant
            shall pay Tenant's Pro Rata Share of the total amount of Expenses
            (defined in Section IV.C.) and Taxes (defined in Section IV.D) for
            each calendar year during the Term. Landlord shall provide Tenant
            with a good faith estimate of the total amount of Expenses and Taxes
            for each calendar year during the Term. On or before the first day
            of each month, Tenant shall pay to Landlord a monthly installment
            equal to one-twelfth of Tenant's Pro Rata Share of Landlord's
            estimate of the total amount of Expenses and Taxes, which initial
            monthly sum is defined in Section I.E. above as the "Tenant's
            Monthly Expense and Tax Payment". If Landlord determines that its
            good faith estimate was incorrect by a material amount, Landlord may
            provide Tenant with a revised estimate. After its receipt of the
            revised estimate, Tenant's Monthly Expense and Tax Payment shall be
            based upon the revised estimate. If Landlord does not provide Tenant
            with an estimate of the total amount of Expenses and Taxes by
            January 1 of a calendar year, Tenant shall continue to pay monthly
            installments based on the previous year's estimate until Landlord
            provides Tenant with the new estimate. Upon delivery of the new
            estimate, an adjustment shall be made for any month for which Tenant
            paid monthly installments based on the previous year's estimate.
            Tenant shall pay Landlord the amount of any underpayment within 30
            days after receipt of the new estimate. Any overpayment shall be
            refunded to Tenant within 30 days or credited against the next due
            future installment(s) of Additional Rent, provided, however, if the
            Term has expired, then any overpayment shall be refunded to Tenant
            within 30 days after receipt of the new estimate.

            As soon as is practical following the end of each calendar year,
            Landlord shall furnish Tenant with a statement of the actual amount
            of Expenses and Taxes for the prior calendar year and Tenant's Pro
            Rata Share of the actual amount of Expenses and Taxes for the prior
            calendar year. If the estimated amount of Expenses and Taxes for the
            prior calendar year is more than the actual amount of Expenses and
            Taxes for the prior calendar year, Landlord shall apply any
            overpayment by Tenant against Additional Rent due or next becoming
            due, provided if the Term expires before the determination of the
            overpayment, Landlord shall refund any overpayment to Tenant after
            first deducting the amount of Rent due. If the estimated amount of
            Expenses and Taxes for the prior calendar year is less than the
            actual amount of Expenses and Taxes for such prior year, Tenant
            shall pay Landlord, within 30 days after its receipt of the
            statement of Expenses and Taxes, any underpayment for the prior
            calendar year.

      C.    Expenses Defined. "Expenses" means all costs and expenses incurred
            in each calendar year in connection with operating, maintaining,
            repairing, and managing the Building and the Property, including,
            but not limited to:

<PAGE>

            1.    Labor costs, including, wages, salaries, social security and

                  persons at or below the level of Portfolio Manager or
                  Portfolio Engineer who are engaged in the operation,
                  management, maintenance or security of the Building and/or the
                  Property; provided that if any employees of Landlord provide
                  services for the Building and other buildings of Landlord,
                  then a prorated portion of such employee's wages, benefits and
                  taxes shall be included in Expenses based on the portion of
                  their working time devoted to the Building.

            2.    Management fees, the cost of equipping and maintaining a
                  management office, accounting and bookkeeping services, legal

                  other administrative costs. Landlord, by itself or through an
                  affiliate, shall have the right to directly perform or provide
                  any services under this Lease (including management services),
                  provided that the cost of any such services shall not exceed
                  the cost that would have been incurred had Landlord entered
                  into an arms-length contract for such services with an
                  unaffiliated entity of comparable skill and experience.

            3.    The cost of services, including amounts paid to service
                  providers and the rental and purchase cost of parts, supplies,
                  tools and equipment, provided that costs of rentals and other
                  related expenses incurred in leasing HVAC, elevators or other
                  equipment ordinarily considered to be of a capital nature may
                  only be included in Expenses in the event that (i) such
                  equipment is used in providing janitorial or similar services,
                  or normal repairs and maintenance, and is not affixed to the
                  Building or the Property, or (ii) such equipment is used in
                  the event of an emergency.

            4.    Premiums and deductibles paid by Landlord for insurance,

                  earthquake, general liability, rental loss, elevator, boiler
                  and other insurance customarily carried from time to time by
                  owners of comparable office buildings.

            5.    Electrical Costs (defined below) and charges for water, gas,
                  steam and sewer, but excluding those charges for which
                  Landlord is reimbursed by tenants. "Electrical Costs" means:
                  (a) charges paid by Landlord for electricity; (b) costs
                  incurred in connection with an energy management program for
                  the Property; and (c) if and to the extent permitted by Law, a
                  fee for the services provided by Landlord in connection with
                  the selection of utility companies and the negotiation and
                  administration of contracts for electricity, provided that
                  such fee shall not exceed 50% of any savings obtained by
                  Landlord. Electrical Costs shall be adjusted as follows: (i)
                  amounts received by Landlord as reimbursement for above
                  standard electrical consumption shall be deducted from
                  Electrical Costs; (ii) the

                                      -6-
<PAGE>

                  cost of electricity incurred to provide overtime HVAC to
                  specific tenants (as reasonably estimated by Landlord) shall
                  be deducted from Electrical Costs; and (iii) if Tenant is
                  billed directly for the cost of building standard electricity
                  to the Premises as a separate charge in addition to Base Rent,
                  the cost of electricity to individual tenant spaces in the
                  Building shall be deducted from Electrical Costs.

            6.    The amortized cost of capital improvements (as distinguished
                  from replacement parts or components installed in the ordinary
                  course of business) made to the Property which are: (a)
                  performed primarily to reduce operating expense costs or
                  otherwise improve the operating efficiency of the Property; or
                  (b) required to comply with any Laws that are enacted, or
                  first interpreted to apply to the Property, after the date of
                  this Lease. The cost of capital improvements shall be
                  amortized by Landlord over lesser of the Payback Period
                  (defined below) or 10 years. The amortized cost of capital
                  improvements may, at Landlord's option, include actual or
                  imputed interest at the rate that Landlord would reasonably be
                  required to pay to finance the cost of the capital
                  improvement. "Payback Period" means the reasonably estimated
                  period of time that it takes for the cost savings resulting
                  from a capital improvement to equal the total cost of the
                  capital improvement, and shall only apply to capital
                  expenditures under item (a) above. Notwithstanding the
                  foregoing, the portion of the annual amortized costs to be
                  included in Expenses in any calendar year with respect to a
                  capital improvement which is intended to reduce expenses or
                  improve the operating efficiency of the Property or Building
                  shall equal the lesser of: (a) such annual amortized costs;
                  and (b) the projected annual amortized reduction in expenses
                  for that portion of the amortization period of the capital
                  improvement which falls within the Term (based on the total
                  cost savings for such period, as reasonably estimated by
                  Landlord).

            7.    All fees, costs, expenses or other amounts payable by Landlord
                  to any association established for the benefit of the Property
                  and/or other properties.

            If Landlord incurs Expenses for the Property together with one or
            more other buildings or properties, whether pursuant to a reciprocal
            easement agreement, common area agreement or otherwise, the shared
            costs and expenses shall be equitably prorated and apportioned
            between the Property and the other buildings or properties. Expenses
            shall not include: the cost of capital improvements (except as set
            forth above); depreciation; interest (except as provided above for
            the amortization of capital improvements); principal payments of
            mortgage and other non-operating debts of Landlord; the cost of
            repairs or other work to the extent Landlord is reimbursed by
            insurance or condemnation proceeds; costs in connection with leasing
            space in the Building, including brokerage commissions; lease
            concessions, including rental abatements and construction
            allowances,

                                      -7-
<PAGE>

            granted to specific tenants; costs incurred in connection with the
            sale, financing or refinancing of the Building; fines, interest and
            penalties incurred due to the late payment of Taxes (defined in
            Section IV.D) or Expenses; organizational expenses associated with
            the creation and operation of the entity which constitutes Landlord;
            any penalties or damages that Landlord pays to Tenant under this
            Lease or to other tenants in the Building under their respective
            leases; the cost of providing any service directly to and paid
            directly by Tenant; sums (other than management fees, it being
            agreed that the management fees included in Expenses are as
            described in Section IV.C.2 above) paid to subsidiaries or other
            affiliates of Landlord for services on or to the Property, Building
            and/or Premises, but only to the extent that the costs of such
            services exceed the competitive cost for such services rendered by
            persons or entities of similar skill, competence and experience;
            attorney's fees and other expenses incurred in connection with
            negotiations or disputes with prospective tenants or tenants or
            other occupants of the Building; the cost or expense of any services
            or benefits provided generally to other tenants in the Building and
            not provided or available to Tenant; any expenses for which Landlord
            has received actual reimbursement (other than through Expenses);
            costs incurred to comply with Laws relating to the removal of
            hazardous material (as defined under applicable Law) which was in
            existence in the Building prior to the Commencement Date, and was of
            such a nature that a federal, State or municipal governmental
            authority, if it had then had knowledge of the presence of such
            hazardous material, in the state, and under the conditions that it
            then existed in the Building, would have then required the removal
            of such hazardous material or other remedial or containment action
            with respect thereto; and costs incurred to remove, remedy, contain,
            or treat hazardous material, which hazardous material is brought
            into the Building after the date hereof by Landlord or any other
            tenant of the Building and is of such a nature, at that time, that a
            federal, State or municipal governmental authority, if it had then
            had knowledge of the presence of such hazardous material, in the
            state, and under the conditions, that it then exists in the
            Building, would have then required the removal of such hazardous
            material or other remedial or containment action with respect
            thereto; and any costs expressly excluded from Expenses elsewhere in
            this Lease.

            If the Building is not at least 95% occupied during any calendar
            year or if Landlord is not supplying services to at least 95% of the
            total Rentable Square Footage of the Building at any time during a
            calendar year, then the Expenses which vary in amount based upon the
            occupancy levels of the Building shall, at Landlord's option, be
            determined as if the Building had been 95% occupied and Landlord had
            been supplying services to 95% of the Rentable Square Footage of the
            Building during that calendar year. If Tenant pays for Tenant's Pro
            Rata Share of Expenses based on increases over a "Base Year" and
            Expenses for a calendar year are determined as provided in the prior
            sentence, Expenses for the Base Year shall also be determined as if
            the Building had been 95% occupied and Landlord had been supplying
            services to 95% of the Rentable Square Footage of the Building. The
            extrapolation of Expenses under this Section shall be performed by
            appropriately adjusting the cost of those components of Expenses
            that are

                                      -8-
<PAGE>

            impacted by changes in the occupancy of the Building. Landlord shall
            (i) not make a profit by charging items to Expenses that are
            otherwise also charged separately to others and (ii) Landlord shall
            not collect Expenses from Tenant and all other tenants/occupants in
            the Building in an amount in excess of what Landlord incurred for
            the items included in Expenses.

      D.    Taxes Defined. "Taxes" shall mean: (1) all real estate taxes and
            other assessments on the Building and/or Property, including, but
            not limited to, assessments for special improvement districts and
            building improvement districts, taxes and assessments levied in
            substitution or supplementation in whole or in part of any such
            taxes and assessments and the Property's share of any real estate
            taxes and assessments under any reciprocal easement agreement,
            common area agreement or similar agreement as to the Property; (2)
            all personal property taxes for property that is owned by Landlord
            and used in connection with the operation, maintenance and repair of
            the Property; and (3) all costs and fees reasonably incurred in
            connection with seeking reductions in any tax liabilities described
            in (1) and (2), including, without limitation, any costs reasonably
            incurred by Landlord for compliance, review and appeal of tax
            liabilities. Without limitation, Taxes shall not include any income,
            capital levy, franchise, capital stock, gift, estate or inheritance
            tax. If an assessment is payable in installments, Taxes for the year
            shall include the amount of the installment and any interest due and
            payable during that year. For all other real estate taxes, Taxes for
            that year shall, at Landlord's election, include either the amount
            accrued, assessed or otherwise imposed for the year or the amount
            due and payable for that year, provided that Landlord's election
            shall be applied consistently throughout the Term. If a change in
            Taxes is obtained for any year of the Term, then Taxes for that year
            will be retroactively adjusted and Landlord shall provide Tenant
            with a credit, if any, based on the adjustment.

      E.    Audit Rights. Tenant may, within 180 days after receiving Landlord's
            statement of Expenses, give Landlord written notice ("Review
            Notice") that Tenant intends to review Landlord's records of the
            Expenses for that calendar year. Within a reasonable time after
            receipt of the Review Notice, Landlord shall make all pertinent
            records available for inspection that are reasonably necessary for
            Tenant to conduct its review. If any records are maintained at a
            location other than the office of the Building, Tenant may either
            inspect the records at such other location or pay for the reasonable
            cost of copying and shipping the records. If Tenant retains an agent
            to review Landlord's records, the agent must be with a licensed CPA
            firm. Tenant shall be solely responsible for all costs, expenses and
            fees incurred for the audit. Within 60 days after the records are
            made available to Tenant, Tenant shall have the right to give
            Landlord written notice (an "Objection Notice") stating in
            reasonable detail any objection to Landlord's statement of Expenses
            for that year. If Tenant fails to give Landlord an Objection Notice
            within the 60 day period or fails to provide Landlord with a Review
            Notice within the 180 day period described above, Tenant shall be
            deemed to have approved Landlord's statement of Expenses and shall
            be barred from raising any claims

                                      -9-
<PAGE>

            regarding the Expenses for that year. If Tenant provides Landlord
            with a timely Objection Notice, Landlord and Tenant shall work
            together in good faith to resolve any issues raised in Tenant's
            Objection Notice. If Landlord and Tenant determine that Expenses for
            the calendar year are less than reported, Landlord shall provide
            Tenant with a credit against the next installment of Rent in the
            amount of the overpayment by Tenant. Likewise, if Landlord and
            Tenant determine that Expenses for the calendar year are greater
            than reported, Tenant shall pay Landlord the amount of any
            underpayment within 30 days. In no event shall Tenant be permitted
            to examine Landlord's records or to dispute any statement of
            Expenses unless Tenant has paid and continues to pay all Rent when
            due.

      F.    Increase in Base Rent. On the fifth anniversary of the Commencement
            Date, the monthly Base Rent per rentable square foot of the Premises
            shall be increased by the greater of (i) the cumulative percentage
            increase in the "Consumer Index" during the five year period ending
            on such anniversary or (ii) $0.156 per rentable square foot of the
            Premises per month. The "Consumer Index" shall mean the Consumer
            Price Index for Urban Wage Earners and Clerical Workers
            (1982-1984=100) U.S. City Average for All Items, as published by the
            United States Department of Labor, Bureau of Labor Statistics. If
            the Consumer Index is discontinued or revised during the Term, then
            such other index or computation with which it is replaced or other
            reasonable replacement as determined by Landlord shall be used.
            Landlord shall submit a statement to Tenant reflecting the increase,
            if any, as provided in this Section. If such statement is delayed,
            Tenant shall continue to pay the Base Rent in effect and shall
            immediately pay to Landlord any deficiency in Base Rent due upon
            submission of such statement. The Base Rent, as adjusted pursuant to
            this Section, shall remain in effect for the balance of the initial
            Term.

V.    COMPLIANCE WITH LAWS; USE.

      The Premises shall be used only for the Permitted Use and for no other use
whatsoever except with Landlord's prior written consent (which may be withheld
in Landlord's sole discretion). Tenant shall not use or permit the use of the
Premises for any purpose which is illegal, dangerous to persons or property or
which, in Landlord's reasonable opinion, unreasonably disturbs any other tenants
of the Building or interferes with the operation of the Building. Tenant shall
comply with all Laws, including the Americans with Disabilities Act, regarding
the operation of Tenant's business and the use, condition, configuration and
occupancy of the Premises. Tenant, within 10 days after receipt, shall provide
Landlord with copies of any notices it receives regarding a violation or alleged
violation of any Laws. Tenant shall comply with the rules and regulations of the
Building attached as EXHIBIT B and such other reasonable rules and regulations
adopted by Landlord from time to time. Tenant shall also cause its agents,
contractors, subcontractors, employees, customers, and subtenants to comply with
all rules and regulations. Landlord shall not knowingly discriminate against
Tenant in Landlord's enforcement of the rules and regulations.

                                      -10-

VI.   SECURITY DEPOSIT; LETTER OF CREDIT.

      The Security Deposit, if any, shall be delivered to Landlord upon the
execution of this Lease by Tenant and shall be held by Landlord without
liability for interest (unless required by Law) as security for the performance
of Tenant's obligations. The Security Deposit is not an advance payment of Rent
or a measure of Tenant's liability for damages. Landlord may, from time to time,
without prejudice to any other remedy, use all or a portion of the Security
Deposit to satisfy past due Rent or to cure any uncured default by Tenant. If
Landlord uses the Security Deposit, Tenant shall on demand restore the Security
Deposit to its original amount. Landlord shall return any unapplied portion of
the Security Deposit to Tenant within 45 days after the later to occur of: (1)
the determination of Tenant's Pro Rata Share of Expenses and Taxes for the final
year of the Term; (2) the date Tenant surrenders possession of the Premises to
Landlord in accordance with this Lease; or (3) the Termination Date. If Landlord
transfers its interest in the Premises, Landlord may assign the Security Deposit
to the transferee and, following the assignment, Landlord shall have no further
liability for the return of the Security Deposit. Landlord shall not be required
to keep the Security Deposit separate from its other accounts. Tenant hereby
waives the provisions of Section 1950.7 of the California Civil Code, or any
similar or successor Laws now or hereinafter in effect.

      The Security Deposit may be in the form of an irrevocable letter of credit
(the "Letter of Credit"), which Letter of Credit shall: (a) be in the amount of
six (6) months of Base Rent due hereunder (at the rate payable for the first 5
years of the Term) and the estimate of Tenant's Monthly Expense and Tax Payment
as set forth in Section I.E above; (b) be issued on the form attached hereto as
EXHIBIT G; (c) name Landlord as its beneficiary; and (d) be drawn on an FDIC
insured financial institution satisfactory to the Landlord. The Letter of Credit
(and any renewals or replacements thereof) shall be for a term of not less than
1 year. Tenant agrees that it shall from time to time, as necessary, whether as
a result of a draw on the Letter of Credit by Landlord pursuant to the terms
hereof or as a result of the expiration of the Letter of Credit then in effect,
renew or replace the original and any subsequent Letter of Credit so that a
Letter of Credit, in the amount required hereunder, is in effect until a date
which is at least 60 days after the Termination Date of the Lease. If Tenant
fails to furnish such renewal or replacement at least 60 days prior to the
stated expiration date of the Letter of Credit then held by Landlord, Landlord
may draw upon such Letter of Credit and hold the proceeds thereof (and such
proceeds need not be segregated) as a Security Deposit pursuant to the terms of
this Article VI. Any renewal or replacement of the original or any subsequent
Letter of Credit shall meet the requirements for the original Letter of Credit
as set forth above, except that such replacement or renewal shall be issued by a
national bank satisfactory to Landlord at the time of the issuance thereof.

      If Landlord draws on the Letter of Credit as permitted in this Lease or
the Letter of Credit, then, upon demand of Landlord, Tenant shall restore the
amount available under the Letter of Credit to its original amount by providing
Landlord with an amendment to the Letter of Credit evidencing that the amount
available under the Letter of Credit has been restored to its original amount.
In the alternative, Tenant may provide Landlord with cash, to be held by
Landlord in accordance with this Article VI, equal to the restoration amount
required under the Letter of Credit.

                                      -11-

VII.  SERVICES TO BE FURNISHED BY LANDLORD.

      A.    Landlord agrees to furnish Tenant with the following services in a
            manner materially consistent with that of the Current Condition
            (defined hereinbelow): (1) Water service for use in the lavatories
            on each floor on which the Premises are located, water for drinking
            fountains and food preparation areas within the Premises, and
            chilled water for cooling of Tenant's computer equipment; (2) Heat
            and air conditioning in season during Normal Business Hours, at such
            temperatures and in such amounts as are consistent with the Current
            Condition or as required by governmental authority. Tenant, upon
            such advance notice as is reasonably required by Landlord, shall
            have the right to receive HVAC service during hours other than
            Normal Business Hours. Tenant shall pay Landlord the standard charge
            for the additional service as reasonably determined by Landlord from
            time to time; (3) Maintenance and repair of the Property as
            described in Section IX.B.; (4) Janitor service on Business Days. If
            Tenant's use, floor covering or other improvements require special
            services in excess of the standard services for the Building, Tenant
            shall pay the additional cost attributable to the special services;
            (5) Elevator service; (6) Electricity to the Premises for general
            office use, in accordance with and subject to the terms and
            conditions in Article X; and (7) such other services as are
            consistent with the Current Condition. The term "Current Condition"
            for purposes of this Lease shall mean the condition of the Building
            and the level and quality of utilities and services, as applicable,
            provided at the Building immediately prior to the Commencement Date.
            The water usage within the Premises, the chilled water usage for the
            cooling of Tenant's computer equipment, and Tenant's HVAC usage
            shall be separately metered. Landlord shall install such meters, and
            the cost thereof, including the cost of installation, operation and
            maintenance thereof, as reasonably determined by Landlord, shall be
            paid by Tenant. Tenant shall pay the cost of its consumption of
            chilled water, and if Tenant uses water or HVAC in excess of the
            Current Condition, then Tenant shall also pay for such excess
            consumption (but without charge, in any event, for depreciation,
            profit, overhead or administration), including the cost of the
            installation, operation, and maintenance of equipment which is
            installed in order to supply the chilled water or the excess
            consumption of water and/or HVAC, and the cost of increased wear and
            tear on existing equipment caused by the chilled water usage or such
            excess consumption, as reasonably determined by Landlord.

      B.    Landlord's failure to furnish, or any interruption or termination
            of, services due to the application of Laws, the failure of any
            equipment, the performance of repairs, improvements or alterations,
            or the occurrence of any event or cause beyond the reasonable
            control of Landlord, or Landlord's failure to provide access to the
            Premises (a "Service Failure") shall not render Landlord liable to
            Tenant, constitute a constructive eviction of Tenant, give rise to
            an abatement of Rent, nor relieve Tenant from the obligation to
            fulfill any covenant or agreement. However, if the Premises, or a
            material portion of the Premises, is made untenantable for a period
            in excess of 3 consecutive Business Days as a result of the Service
            Failure,

                                      -12-
<PAGE>

            then Tenant, as its sole remedy, shall be entitled to receive an
            abatement of Rent payable hereunder retroactive to the beginning of
            the Service Failure and ending on the day the service has been
            restored. If the entire Premises has not been rendered untenantable
            by the Service Failure, the amount of abatement that Tenant is
            entitled to receive shall be prorated based upon the percentage of
            the Premises rendered untenantable and not used by Tenant. In no
            event, however, shall Landlord be liable to Tenant for any loss or
            damage, including the theft of Tenant's Property (defined in Article
            XV), arising out of or in connection with the failure of any
            security services, personnel or equipment. Furthermore, if any
            Service Failure is not due to the intentional acts or negligence of
            Tenant and shall continue for more than 180 consecutive days, then
            Tenant shall have the right to terminate this Lease during the first
            10 Business Days of each calendar month following the end of such
            180-day period until such time as Landlord has cured the Service
            Failure, which right may be exercised only by delivery of 30 days'
            notice to Landlord (the "Service Failure Termination Notice") during
            such 10 Business Day period, and shall be effective as of a date set
            forth in the Service Failure Termination Notice (the "Service
            Failure Termination Date"), which Service Failure Termination Date
            shall not be less than 30 days, and not more than 90 days, following
            the delivery of the Service Failure Termination Notice.
            Notwithstanding anything contained in this Section VII.B to the
            contrary, Tenant's Service Failure Termination Notice shall be null
            and void if Landlord cures such Service Failure within such 30 day
            period following receipt of the Service Failure Termination Notice.
            Notwithstanding the foregoing, Tenant shall not have the right to
            terminate this Lease pursuant to the terms of this Section VII.B,
            if, as of the date of delivery by Tenant of the Service Failure
            Termination Notice, (A) the first trust deed holder of the Building,
            if any (the "Bank") has recorded a notice of default on the Building
            or filed a notice evidencing a legal action by the Bank against
            Landlord on the Building, and (B) the Bank diligently proceeds to
            gain possession of the Premises and, to the extent Bank does gain
            possession of the Premises, the Bank diligently proceeds to cure
            such Service Failure within 15 Business Days following the 60th
            consecutive Business Day or 90th non-consecutive Business day in the
            one year period upon written notice to Landlord without any
            liability whatsoever to Landlord.

VIII. LEASEHOLD IMPROVEMENTS.

      All improvements to the Premises (collectively, "Leasehold Improvements")
shall be owned by Landlord and shall remain upon the Premises without
compensation to Tenant. However, Landlord, by written notice to Tenant given at
least 60 days prior to the Termination Date, may require Tenant to remove, at
Tenant's expense: (1) Cable (defined in Section IX.A) installed after the
Commencement Date by or for the exclusive benefit of Tenant and located in the
Premises or other portions of the Building; and (2) any Leasehold Improvements
that are performed by or for the benefit of Tenant after the Commencement Date
and, in Landlord's reasonable judgment, are of a nature that would require
removal and repair costs that are materially in excess of the removal and repair
costs associated with standard office

                                      -13-
<PAGE>

improvements (collectively referred to as "Required Removables"). Without
limitation, it is agreed that Required Removables include internal stairways,
raised floors, personal baths and showers, vaults, rolling file systems and
structural alterations and modifications of any type, but Required Removables
shall not include any such items installed before the Commencement Date. The
Required Removables designated by Landlord shall be removed by Tenant before the
Termination Date, provided that upon prior written notice to Landlord, Tenant
may remain in the Premises for up to 5 days after the Termination Date for the
sole purpose of removing the Required Removables. Tenant's possession of the
Premises shall be subject to all of the terms and conditions of this Lease,
including the obligation to pay Rent on a per diem basis at the rate in effect
for the last month of the Term. Tenant shall repair damage caused by the
installation or removal of Required Removables. If Tenant fails to remove any
Required Removables or perform related repairs in a timely manner, Landlord, at
Tenant's expense, may remove and dispose of the Required Removables and perform
the required repairs. Tenant, within 30 days after receipt of an invoice (which
shall be accompanied by reasonable supporting documentation of the amounts set
forth in such invoice), shall reimburse Landlord for the reasonable costs
incurred by Landlord. Notwithstanding the foregoing, Tenant, at the time it
requests approval for a proposed Alteration (defined in Section IX.C), may
request in writing that Landlord advise Tenant whether the Alteration or any
portion of the Alteration will be designated as a Required Removable. Within 10
days after receipt of Tenant's request, Landlord shall advise Tenant in writing
as to which portions of the Alteration, if any, will be considered to be
Required Removables.

IX.   REPAIRS AND ALTERATIONS.

      A.    Tenant's Repair Obligations. Tenant shall, at its sole cost and
            expense, promptly perform all maintenance and repairs to the
            Premises that are not Landlord's express responsibility under this
            Lease, and shall keep the Premises in good condition and repair,
            reasonable wear and tear and damage due to casualty (subject to
            Section XVII below) or condemnation excepted. Tenant's obligations
            shall consist of repairs to: (1) floor covering; (2) interior
            partitions; (3) doors; (4) the interior side of demising walls; (5)
            electronic, phone and data cabling and related equipment
            (collectively, "Cable") that is installed by or for the exclusive
            benefit of Tenant and located in the Premises or other portions of
            the Building; (6) supplemental air conditioning units, private
            showers and kitchens, including hot water heaters, plumbing, and
            similar facilities serving Tenant exclusively; and (7) Alterations
            performed by contractors retained by Tenant, including related HVAC
            balancing. All work shall be performed in accordance with the rules
            and procedures described in Section IX.C. below. If Tenant fails to
            make any repairs to the Premises for more than 15 days after notice
            from Landlord (although notice shall not be required if there is an
            emergency), Landlord may make the repairs, and Tenant shall pay the
            reasonable cost of the repairs to Landlord within 30 days after
            receipt of an invoice, together with an administrative charge in an
            amount equal to 7% of the cost of the repairs. Notwithstanding the
            foregoing, if more than 15 days is reasonably required to complete
            such repairs, then Tenant shall be allowed additional time (not to
            exceed 60 days) as is reasonably necessary to complete such repairs
            so long as: (i) Tenant commences the work within 15 days,

                                      -14-
<PAGE>
            and (ii) Tenant diligently pursues a course of action to complete
            the work. However, if Tenant's failure to complete the work within
            15 days creates a hazardous condition, then the failure may be cured
            immediately by Landlord.

      B.    Landlord's Repair Obligations. Landlord shall use commercially
            reasonable efforts to keep and maintain in the Current Condition and
            make repairs to and perform maintenance upon (in order to maintain
            the Current Condition): (1) structural elements of the Building; (2)
            mechanical (including HVAC), electrical, plumbing and fire/life
            safety systems serving the Building in general; (3) Common Areas;
            (4) the roof of the Building; (5) exterior windows of the Building;
            and (6) elevators serving the Building. Landlord shall promptly make
            repairs (considering the nature and urgency of the repair) for which
            Landlord is responsible. Tenant hereby waives any and all rights
            under and benefits of subsection 1 of Section 1932, and Sections
            1941 and 1942 of the California Civil Code, or any similar or
            successor Laws now or hereinafter in effect.

      C.    Alterations. Tenant shall not make alterations, additions or
            improvements to the conditioned Premises or install any Cable in the
            Premises or other portions of the Building (collectively referred to
            as "Alterations") without first obtaining the written consent of
            Landlord in each instance, which consent shall not be unreasonably
            withheld or delayed. However, Landlord's consent shall not be
            required for any Alteration that satisfies all of the following
            criteria (a "Cosmetic Alteration"): (1) is of a cosmetic nature such
            as painting, wallpapering, hanging pictures and installing
            carpeting; (2) is not visible from the exterior of the Premises or
            Building; (3) will not affect the systems or structure of the
            Building; and (4) does not require work to be performed inside the
            demising walls or above the ceiling of the Premises. However, even
            though consent is not required, the performance of Cosmetic
            Alterations shall be subject to all the other provisions of this
            Section IX.C. Prior to starting work, Tenant shall furnish Landlord
            with plans and specifications reasonably acceptable to Landlord;
            names of contractors reasonably acceptable to Landlord (provided
            that Landlord may designate specific contractors with respect to
            Building systems provided the work of such contractors is
            competitively priced); copies of contracts; necessary permits and
            approvals; evidence of contractor's and subcontractor's insurance in
            amounts reasonably required by Landlord; and any security for
            performance that is reasonably required by Landlord. Changes to the
            plans and specifications must also be submitted to Landlord for its
            approval. Alterations shall be constructed in a good and workmanlike
            manner using materials of a quality that is at least equal to the
            quality designated by Landlord as the minimum standard for the
            Building. Landlord may designate reasonable rules, regulations and
            procedures for the performance of work in the Building and, to the
            extent reasonably necessary to avoid disruption to the occupants of
            the Building, shall have the right to designate the time when
            Alterations may be performed. Tenant shall reimburse Landlord within
            30 days after receipt of an invoice for sums reasonably paid by
            Landlord for third party examination of Tenant's plans for
            non-Cosmetic Alterations. IN addition, within 30 days after receipt
            of an invoice from Landlord, Tenant shall

                                      -15-
<PAGE>

            pay Landlord a fee for Landlord's oversight and coordination of any
            non-Cosmetic Alterations equal to 7% of the cost of the non-Cosmetic
            Alterations. Upon completion, Tenant shall furnish "as-built" plans
            (except for Cosmetic Alterations), completion affidavits, full and
            final waivers of lien in recordable form, and receipted bills
            covering all labor and materials. Tenant shall assure that the
            Alterations comply with all insurance requirements and Laws.
            Landlord's approval of an Alteration shall not be a representation
            by Landlord that the Alteration complies with applicable Laws or
            will be adequate for Tenant's use.

X.    USE OF ELECTRICAL SERVICES BY TENANT.

      A.    Electricity used by Tenant in the Premises shall be paid for by
            Tenant by a separate charge payable by Tenant to Landlord within 30
            days after billing by Landlord; provided, however, that for so long
            as the Premises include the entire 4100 Building, Tenant shall have
            the option to arrange and pay for electricity consumed in the 4100
            Building through a direct agreement with the utility supplier.
            Electrical service to the Premises may be furnished by one or more
            companies providing electrical generation, transmission and
            distribution services, and the cost of electricity may consist of
            several different components or separate charges for such services,
            such as generation, distribution and stranded cost charges.
            Notwithstanding the foregoing, Landlord shall have the exclusive
            right to select any company providing electrical service to the
            Premises, to aggregate the electrical service for the Property and
            Premises with other buildings, to purchase electricity through a
            broker and/or buyers group and to change the providers and manner of
            purchasing electricity, provided that the electrical service
            provided to the Premises: (1) shall be priced at or below the price
            Tenant could reasonably expect to attain in a direct agreement with
            the utility supplier; (2) shall be available and deliverable to the
            Premises without interruption to the same extent as reasonably could
            be expected if such service was supplied directly by the same
            utility supplier as is supplying service on the Commencement Date;
            and (3) Tenant is not required to bear any cost or expense (whether
            directly or as a component of Expenses) or suffer any disruption in
            supply in connection with the change-over in the electrical service
            supplier. Tenant's electrical usage in the 4100 Building is
            separately metered. If Landlord reasonably determines that Tenant's
            electrical usage exceeds what is standard in the 4000 Building, in
            which case the cost thereof, including the cost of installation,
            operation and maintenance, as reasonably determined by Landlord,
            shall be paid by Tenant. Landlord shall be entitled to receive a
            profit (if permitted by Law) in connection with Landlord's selection
            of utility companies and the negotiation and administration of
            contracts for electricity provided the aggregate cost of electricity
            supplied to the Property (including charges for services such as
            generation, distribution and stranded costs) does not exceed the
            cost Landlord could reasonably expect to attain in a direct
            agreement with the utility supplier.

      B.    Tenant's use of electrical service shall not exceed, either in
            voltage, rated capacity or overall load, the Current Condition. If
            Tenant requests permission to consume

                                      -16-
<PAGE>

            excess electrical service, Landlord may refuse to consent or may
            condition consent upon conditions that Landlord reasonably elects
            (including, without limitation, the installation of utility service
            upgrades, additional meters or submeters, air handlers or cooling
            units), and the additional usage (to the extent permitted by Law),
            and installation and maintenance costs shall be paid by Tenant. If
            Tenant uses electricity in excess of the Current Condition, then
            Tenant shall pay for such excess consumption (but without charge, in
            any event, for depreciation, profit, overhead of administration),
            including the cost of increased wear and tear on existing equipment
            caused by such excess consumption, as reasonably determined by
            Landlord.

XI.   ENTRY BY LANDLORD.

      Landlord, its agents, contractors and representatives may enter the
Premises to inspect or during the last 12 months of the Term show the Premises,
to clean and make reasonable repairs, alterations or additions to the Premises,
and to conduct or facilitate reasonable repairs, alterations or additions to any
portion of the Building, including other tenants' premises. Except in
emergencies or to provide janitorial and other Building services after Normal
Business Hours, Landlord shall provide Tenant with reasonable prior notice of
entry into the Premises, which may be given orally. If reasonably necessary for
the protection and safety of Tenant and its employees, Landlord shall have the
right to temporarily close all or a portion of the Premises to perform repairs,
alterations and additions. However, except in emergencies, Landlord will not
close the Premises if the work can reasonably be completed on weekends and after
Normal Business Hours. Entry by Landlord shall not constitute constructive
eviction, or entitle Tenant to an abatement or reduction of Rent (except as
expressly set forth in this Lease). Notwithstanding the foregoing, except in
emergency situations as determined by Landlord, Landlord shall exercise
reasonable efforts not to unreasonably interfere with the conduct of the
business of Tenant in the Premises. However, the foregoing shall not require
Landlord to perform work after Normal Business Hours unless Tenant agrees to
reimburse Landlord for the extra cost incurred in connection with such work
which exceeds the cost for such work which would have been incurred had it been
performed during Normal Business Hours. Notwithstanding anything to the contrary
set forth in this Article XI, Tenant may designate certain areas of the Premises
as "Secured Areas" should Tenant require such areas for the purpose of securing
certain valuable property or confidential information. In connection with the
foregoing, Landlord shall not enter such Secured Areas except in the event of an
emergency. Landlord need not clean any area designated by Tenant as a Secured
Area and shall only maintain or repair such Secured Areas to the extent (i) such
repair or maintenance is required in order to maintain and repair the Building
structure and/or the Building systems and equipment; (ii) as required by Law, or
(iii) in response to specific requests by Tenant and in accordance with a
schedule reasonably designated by Tenant, subject to Landlord's reasonable
approval.

XII.  ASSIGNMENT AND SUBLETTING.

      A.    Except in connection with a Permitted Transfer (defined in Section
            XII.E. below), Tenant shall not assign, sublease, transfer or
            encumber any interest in this Lease or allow any third party to use
            any portion of the Premises (collectively or

                                      -17-
<PAGE>

            individually, a "Transfer") without the prior written consent of
            Landlord, which consent shall not be unreasonably withheld,
            conditioned or delayed. Without limitation, it is agreed that
            Landlord's consent shall not be considered unreasonably withheld if:
            (1) the proposed transferee's financial condition is not reasonably
            adequate to meet the obligations imposed on Tenant by this Lease (or
            in the event of a sublease, the obligations imposed by the
            sublease); (2) the proposed transferee's use is not a Permitted use
            and either is not suitable for the Building considering the business
            of the other tenants and the Building's prestige, or would result in
            a violation of another tenant's rights; (3) the proposed transferee
            is an occupant of the Building or Property, or a governmental agency
            (unless Landlord, with respect to the Building, has leased space to,
            or approved subleases with governmental agencies or
            instrumentalities thereof which are comparable (in terms of use,
            security issues, express or implied power of eminent domain,
            reputation, character and size of space in the Building); (4) Tenant
            is in Monetary Default (defined in Section XIX.A below) or material
            non-Monetary Default after the expiration of the notice and cure
            periods in this Lease; or (5) any portion of the Building or
            Premises would become subject to additional or different Laws as a
            consequence of the proposed Transfer. Tenant shall not be entitled
            to receive any consequential, special or indirect damages based upon
            a claim that Landlord unreasonably withheld its consent to a
            proposed Transfer. Instead, any such claim of Tenant shall be
            limited to the foreseeable, direct and actual damages incurred by
            Tenant. Any attempted Transfer in violation of this Article shall,
            at Landlord's option, be void. Consent by Landlord to one or more
            Transfer(s) shall not operate as a waiver of Landlord's rights to
            approve any subsequent Transfers. In no event shall any Transfer or
            Permitted Transfer release or relieve Tenant from any obligation
            under this Lease.

      B.    As part of its request for Landlord's consent to a Transfer, Tenant
            shall provide Landlord with financial statements for the proposed
            transferee, a complete copy of the proposed assignment, sublease and
            other contractual documents and such other information as Landlord
            may reasonably request. Landlord shall, by written notice to Tenant
            within 20 days of its receipt of the required information and
            documentation, either consent to the Transfer by the execution of a
            consent agreement in a form reasonably designated by Landlord or
            reasonably refuse to consent to the Transfer in writing. If Landlord
            refuses to give such consent, its notice to Landlord shall specify
            the grounds for such refusal. Tenant shall pay Landlord a review fee
            equal to the actual out-of-pocket costs, expenses, and attorney fees
            incurred for Landlord's review of any Permitted Transfer or
            requested Transfer, including the preparation and negotiation of any
            consent required of Landlord related to a Transfer. Notwithstanding
            the foregoing, provided that neither the Tenant nor the proposed
            transferee requests any changes to this Lease or Landlord's standard
            form of consent in connection with the proposed Transfer, such costs
            and expenses shall not exceed $1,500.00.

      C.    Tenant shall pay Landlord 50% of all rent and other consideration
            which Tenant receives as a result of a Transfer that is in excess of
            the Rent payable to Landlord

                                      -18-
<PAGE>

            for the portion of the Premises and Term covered by the Transfer
            (the "Transfer Premium"). Tenant shall pay Landlord for Landlord's
            share of any excess within 30 days after Tenant's receipt of such
            excess consideration. Tenant may deduct from the excess all
            reasonable and customary expenses directly incurred by Tenant
            attributable to the Transfer, including brokerage fees, legal fees
            and construction costs, and any other reasonable and customary costs
            directly incurred by Tenant in connection with the subject Transfer.
            In the event that Tenant does not receive a profit and is at a loss
            for a Transfer, such loss shall be carried forward into the
            following calendar year for purposes of calculating amounts
            hereunder to be paid to Landlord.

      D.    Except as provided below with respect to a Permitted Transfer, if
            Tenant is a corporation, limited liability company, partnership, or
            similar entity, and if the entity which owns or controls a majority
            of the voting shares/rights at any time changes for any reason
            (including but not limited to a merger, consolidation or
            reorganization), such change of ownership or control shall
            constitute a Transfer. The foregoing shall not apply so long as
            Tenant is an entity whose outstanding stock is listed on a
            recognized security exchange, or if at least 80% of its voting stock
            is owned by another entity, the voting stock of which is so listed.

      E.    So long as Tenant is not entering into the Permitted Transfer for
            the purpose of avoiding or otherwise circumventing the remaining
            terms of this Article XII, Tenant may assign its entire interest
            under this Lease, without the consent of Landlord, to (i) an
            affiliate, subsidiary, or parent of Tenant, or a corporation,
            partnership or other legal entity wholly owned by Tenant
            (collectively, an "Affiliated Party"), or (ii) a successor to Tenant
            by purchase, merger, consolidation or reorganization, provided that
            all of the following conditions are satisfied (each such Transfer a
            "Permitted Transfer"): (1) Tenant is not in default under this
            Lease; (2) the Permitted Use does not allow the Premises to be used
            for retail purposes; (3) Tenant shall give Landlord written notice
            at least 30 days prior to the effective date of the proposed
            Permitted Transfer; (4) with respect to a proposed Permitted
            Transfer to an Affiliated Party, Tenant continues to have a net
            worth equal to or greater than Tenant's net worth at the date of
            this Lease; and (5) with respect to a purchase, merger,
            consolidation or reorganization or any Permitted Transfer which
            results in Tenant ceasing to exist as a separate legal entity, (a)
            Tenant's successor shall own all or substantially all of the assets
            of Tenant, and (b) Tenant's successor shall have a net worth which
            is at least equal to the greater of Tenant's net worth at the date
            of this Lease or Tenant's net worth as of the day prior to the
            proposed purchase, merger, consolidation or reorganization. Tenant's
            notice to Landlord shall include information and documentation
            showing that each of the above conditions has been satisfied. If
            requested by Landlord, Tenant's successor shall sign a commercially
            reasonable form of assumption agreement. As used herein, (A)
            "parent" shall mean a company which owns a majority of Tenant's
            voting equity; (B) "subsidiary" shall mean an entity wholly owned by
            Tenant or at least 51% of whose voting equity is owned by Tenant;
            and (C) "affiliate" shall mean an entity controlled by, controlling
            or under common

                                      -19-

            control with Tenant. Notwithstanding the foregoing, if any parent,
            affiliate or subsidiary to which this Lease has been assigned or
            transferred subsequently sells or transfers its voting equity or its
            interest under this Lease other than to another parent, subsidiary
            or affiliate of the original Tenant named hereunder, such sale or
            transfer shall be deemed to be a Transfer requiring the consent of
            Landlord hereunder.

      F.    Notwithstanding anything to the contrary contained in this Article
            XII (but not with respect to transactions occurring under Sections
            XII.E), in the event Tenant contemplates a Transfer of all or a
            portion of the Premises, Tenant shall give Landlord notice (the
            "Intention to Transfer Notice") of such contemplated Transfer
            (whether or not the contemplated transferee or the terms of such
            contemplated Transfer have been determined). The Intention to
            Transfer Notice shall specify the portion of and amount of rentable
            square feet of the Premises which Tenant intends to Transfer (the
            "Contemplated Transfer Space"), the contemplated date of
            commencement of the Contemplated Transfer (the "Contemplated
            Effective Date"), and the contemplated length of the term of such
            contemplated Transfer, and shall specify that such Intention to
            Transfer Notice is delivered to Landlord pursuant to this Section
            XII.F in order to allow Landlord to elect to recapture and terminate
            Tenant's Lease of the Contemplated Transfer Space. Thereafter,
            Landlord shall have the option, by giving written notice to Tenant
            within 20 days after receipt of any Intention to Transfer Notice, to
            recapture the Contemplated Transfer Space. Such recapture shall
            cancel and terminate this Lease with respect to such Contemplated
            Transfer Space as of the Contemplated Effective Date, provided that
            Landlord shall separately demise the Contemplated Transfer Space, at
            Landlord's cost, if Tenant would have entered into the Transfer
            without separately demising the Contemplated Transfer Space. In the
            event of a recapture by Landlord, if this Lease shall be canceled
            with respect to less than the entire Premises, the Rent reserved
            herein shall be prorated on the basis of the number of rentable
            square feet retained by Tenant in proportion to the number of
            rentable square feet contained in the Premises, and this Lease as so
            amended shall continue thereafter in full force and effect, and upon
            request of either party, the parties shall execute written
            confirmation of the same. If Landlord declines, or fails to elect in
            a timely manner, to recapture such Contemplated Transfer Space under
            this Section XII.F, then, subject to the other terms of this Article
            XII, for a period of 1 year (the "One Year Period") commencing on
            the last day of such 20 day period, Landlord shall not have any
            right to recapture the Contemplated Transfer Space with respect to
            any Transfer made during the One Year Period, provided that any such
            Transfer is substantially on the terms set forth in the Intention to
            Transfer Notice; provided however, that any such Transfer shall be
            subject to the remaining terms of this Article XII. If such a
            Transfer is not so consummated within the One Year Period (or if a
            Transfer is so consummated, then upon the expiration of the term of
            any Transfer of such Contemplated Transfer Space consummated within
            such One Year Period), Tenant shall again be required to submit a
            new Intention to Transfer

                                      -20-
<PAGE>

            Notice to Landlord with respect any contemplated Transfer, as
            provided above in this Article XII.

XIII. LIENS.

      Tenant shall not permit mechanic's or other liens to be placed upon the
Property, Premises or Tenant's leasehold interest in connection with any work or
service done or purportedly done by or for benefit of Tenant. If a lien is so
placed, Tenant shall, within 10 days of notice from Landlord of the filing of
the lien, fully discharge the lien by settling the claim which resulted in the
lien or by bonding or insuring over the lien in the manner prescribed by the
applicable lien Law. If Tenant fails to discharge the lien, then, in addition to
any other right or remedy of Landlord, Landlord may bond or insure over the lien
or otherwise discharge the lien. Tenant shall reimburse Landlord for any amount
paid by Landlord to bond or insure over the lien or discharge the lien,
including, without limitation, reasonable attorneys' fees (if and to the extent
permitted by Law) within 30 days after receipt of an invoice from Landlord,
together with reasonable supporting documentation.

XIV.  INDEMNITY AND WAIVER OF CLAIMS.

      A.    Except to the extent caused by the negligence or willful misconduct
            of Landlord or any Landlord Related Parties (defined below), Tenant
            shall indemnify, defend and hold Landlord, its trustees, members,
            principals, beneficiaries, partners, officers, directors, employees,
            Mortgagee(s) (defined in Article XXVI) and agents ("Landlord Related
            Parties") harmless against and from all liabilities, obligations,
            damages, penalties, claims, actions, costs, charges and expenses,
            including, without limitation, reasonable attorneys' fees and other
            professional fees (if and to the extent permitted by Law), which may
            be imposed upon, incurred by or asserted against Landlord or any of
            the Landlord Related Parties and arising out of or in connection
            with any damage or injury occurring in the Premises during the Term
            or any period during which Tenant holds over in the Premises after
            the expiration of the Term, or any acts or omissions (including
            violations of Law) of Tenant, the Tenant Related Parties (defined
            below) or any of Tenant's transferees, contractors or licensees, or
            any breach by Tenant hereunder.

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

                                      -21-
<PAGE>

      C.    Landlord and the Landlord Related Parties shall not be liable for,
            and Tenant waives, all claims for loss or damage to Tenant's
            business or loss, theft or damage to Tenant's Property or the
            property of any person claiming by, through or under Tenant
            resulting from: (1) wind or weather; (2) the failure of any
            sprinkler, heating or air-conditioning equipment, any electric
            wiring or any gas, water or steam pipes; (3) the backing up of any
            sewer pipe or downspout; (4) the bursting, leaking or running of any
            tank, water closet, drain or other pipe; (5) water, snow or ice upon
            or coming through the roof, skylight, stairs, doorways, windows,
            walks or any other place upon or near the Building; (6) any act or
            omission of any party other than Landlord or Landlord Related
            Parties; and (7) any causes not reasonably within the control of
            Landlord. Tenant shall insure itself against such losses under
            Article XV below. Notwithstanding the foregoing, except as provided
            in Article XVI to the contrary, Tenant shall not be required to
            waive any claims against Landlord (other than for loss or damage to
            Tenant's business) where such loss or damage is due to the
            negligence or willful misconduct of Landlord or any Landlord Related
            Parties. Nothing herein shall be construed as to diminish the repair
            and maintenance obligations of Landlord contained elsewhere in this
            Lease.

XV.   INSURANCE.

      Tenant shall carry and maintain the following insurance ("Tenant's
Insurance"), at its sole cost and expense: (1) Commercial General Liability
Insurance applicable to the Premises and its appurtenances providing, on an
occurrence basis, a minimum combined single limit of $2,000,000.00; (2) All Risk
Property/Business Interruption Insurance, with Broad form water damage including
an Earthquake Sprinkler Leakage endorsement, written at replacement cost value
and with a replacement cost endorsement covering all of Tenant's trade fixtures,
equipment, furniture and other personal property within the Premises ("Tenant's
Property"); (3) Workers' Compensation Insurance as required by the state in
which the Premises is located and in amounts as may be required by applicable
statute; and (4) Employers Liability Coverage of at least $1,000,000.00 per
occurrence. Any company writing any of Tenant's Insurance shall have an A.M.
Best rating of not less than A-VIII. All Commercial General Liability Insurance
policies shall name Tenant as a named insured and Landlord (or any successor),
Equity Office Properties Trust, a Maryland real estate investment trust, EOP
Operating Limited Partnership, a Delaware limited partnership, Equity Office
Properties Management Corp., a Delaware corporation, and their respective
members, principals, beneficiaries, partners, officers, directors, employees,
and agents, and other designees of Landlord as the interest of such designees
shall appear, as additional insureds. All policies of Tenant's Insurance shall
contain endorsements that the insurer(s) shall give Landlord and its designees
at least 30 days' advance written notice of any change, cancellation,
termination or lapse of insurance. Tenant shall provide Landlord with a
certificate of insurance evidencing Tenant's Insurance prior to the earlier to
occur of the Commencement Date or the date Tenant is provided with possession of
the Premises for any reason, and upon renewals at least 15 days prior to the
expiration of the insurance coverage. So long as the same is available at
commercially reasonable rates, Landlord shall maintain so called All Risk
property insurance on the Building at replacement cost value, as reasonably
estimated

                                      -22-
<PAGE>

by Landlord. Except as specifically provided to the contrary, the limits of
either party's' insurance shall not limit such party's liability under this
Lease.

XVI.  SUBROGATION.

      Notwithstanding anything in this Lease to the contrary, Landlord and
Tenant hereby waive and shall cause their respective insurance carriers to waive
any and all rights of recovery, claim, action or causes of action against the
other and their respective trustees, principals, beneficiaries, partners,
officers, directors, agents, and employees, for any loss or damage that may
occur to Landlord or Tenant or any party claiming by, through or under Landlord
or Tenant, as the case may be, with respect to Tenant's Property, the Building,
the Premises, any additions or improvements to the Building or Premises, or any
contents thereof, including all rights of recovery, claims, actions or causes of
action arising out of the negligence of Landlord or any Landlord Related Parties
or the negligence of Tenant or any Tenant Related Parties, which loss or damage
is (or would have been, had the insurance required by this Lease been carried)
covered by insurance.

XVII. CASUALTY DAMAGE.

      A.    If all or any part of the Premises is damaged by fire or other
            casualty, Tenant shall immediately notify Landlord in writing.
            During any period of time that all or a material portion of the
            Premises is rendered untenantable as a result of a fire or other
            casualty, the Rent shall abate for the portion of the Premises that
            is untenantable and not used by Tenant. Landlord shall have the
            right to terminate this Lease if: (1) the Building shall be damaged
            so that, in Landlord's reasonable judgment, substantial alteration
            or reconstruction of the Building lasting more than 180 days shall
            be required (whether or not the Premises has been damaged); (2)
            Landlord is not permitted by Law to rebuild the Building in
            substantially the same form as existed before the fire or casualty;
            (3) the Premises have been materially damaged and there is less than
            2 years of the Term remaining on the date of the casualty; (4) any
            Mortgagee requires that the insurance proceeds be applied to the
            payment of the mortgage debt; or (5) a material uninsured loss to
            the Building occurs. Landlord may exercise its right to terminate
            this Lease by notifying Tenant in writing within 90 days after the
            date of the casualty. If Landlord does not terminate this Lease,
            Landlord shall commence and proceed with reasonable diligence to
            repair and restore the Building and the Leasehold Improvements
            (excluding any Alterations that were performed by Tenant in
            violation of this Lease). However, in no event shall Landlord be
            required to spend more than the insurance proceeds received by
            Landlord (plus the applicable deductible amount, provided that
            Landlord shall in no event be required to spend the deductible
            amount in the event of damage by earthquake or acts of terrorism),
            provided that if Landlord does not have sufficient insurance
            proceeds (taking into account the applicable deductible amount,
            provided that Landlord shall in no event be required to spend the
            deductible amount in the event of damage by earthquake or acts of
            terrorism) to substantially complete the restoration of the
            Leasehold Improvements in the Premises and Landlord elects not to
            fund any

                                      -23-
<PAGE>

            shortfall, Landlord shall so notify Tenant and Tenant, within 10
            days thereafter, shall have the right to terminate this Lease by the
            giving of written notice to Landlord. Landlord shall not be liable
            for any loss or damage to Tenant's Property or to the business of
            Tenant resulting in any way from the fire or other casualty or from
            the repair and restoration of the damage. Landlord and Tenant hereby
            waive the provisions of any Law relating to the matters addressed in
            this Article, and agree that their respective rights for damage to
            or destruction of the Premises shall be those specifically provided
            in this Lease.

      B.    If all or any portion of the Premises shall be made untenantable by
            fire or other casualty, Landlord shall, with reasonable promptness
            but in all events within 90 days from the date of such occurrence,
            cause an architect or general contractor selected by Landlord to
            provide Landlord and Tenant with a written estimate of the amount of
            time required to substantially complete the repair and restoration
            of the Premises and make the Premises tenantable again, using
            standard working methods ("Completion Estimate"). If the Completion
            Estimate indicates that the Premises cannot be made tenantable
            within 270 days from the date of the damage, then regardless of
            anything in Section XVII.A above to the contrary, either party shall
            have the right to terminate this Lease by giving written notice to
            the other of such election within 20 days after receipt of the
            Completion Estimate. The Premises shall not be considered tenantable
            until all necessary repairs and reconstruction work has been
            substantially completed therein and substantially all necessary
            parking and access to the Premises is available to Tenant. Tenant,
            however, shall not have the right to terminate this Lease if the
            fire or casualty was caused by the negligence or intentional
            misconduct of Tenant, Tenant Related Parties or any of Tenant's
            contractors or licensees. In addition, Tenant shall have the right
            to terminate this Lease if: (1) a substantial portion of the
            Premises has been damaged by fire or other casualty and such damage
            cannot reasonably be repaired within 60 days after receipt of the
            Completion Estimate; (2) there is less than 1 year of the Term
            remaining on the date of such casualty; (3) the casualty was not
            caused by the negligence or intentional misconduct of Tenant or its
            agents, employees or contractors; and (4) Tenant provides Landlord
            with written notice of its intent to terminate within 30 days after
            the date of the fire or other casualty. Notwithstanding the
            foregoing, if Tenant was entitled to but elected not to exercise its
            right to terminate this Lease and Landlord does not substantially
            complete the repair and restoration of the Premises within 2 months
            after the expiration of the estimated period of time set forth in
            the Completion Estimate, which period shall be extended to the
            extent of any Reconstruction Delays, then Tenant may terminate this
            Lease by written notice to Landlord within 15 days after the
            expiration of such period, as the same may be extended, but prior to
            substantial completion of the Premises. For purposes of this Lease,
            the term "Reconstruction Delays" shall mean: (i) any delays caused
            by Tenant; and (ii) any delays caused by events of Force Majeure
            (defined in Section XXXI.D below).

                                      -24-
<PAGE>

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

XVIII. CONDEMNATION.

      Either party may terminate this Lease if the whole or any material part of
the Premises shall be taken or condemned for any public or quasi-public use
under Law, by eminent domain or private purchase in lieu thereof (a "Taking").
Landlord shall also have the right to terminate this Lease if there is a Taking
of any portion of the Building or Property which would leave the remainder of
the Building unsuitable for use as an office building in a manner comparable to
the Building's use prior to the Taking. In order to exercise its right to
terminate the Lease, Landlord or Tenant, as the case may be, must provide
written notice of termination to the other within 45 days after the terminating
party first receives notice of the Taking. Any such termination shall be
effective as of the date the physical taking of the Premises or the portion of
the Building or Property occurs. If this Lease is not terminated, the Rentable
Square Footage of the Building, the Rentable Square Footage of the Premises and
Tenant's Pro Rata Share shall, if applicable, be appropriately adjusted. In
addition, Rent for any portion of the Premises taken or condemned shall be
abated during the unexpired Term of this Lease effective when the physical
taking of the portion of the Premises occurs. All compensation awarded for a
Taking, or sale proceeds, shall be the property of Landlord, any right to
receive compensation or proceeds being expressly waived by Tenant. However,
Tenant may file a separate claim at its sole cost and expense for Tenant's
Property and Tenant's reasonable relocation expenses, provided the claim is
payable separately to Tenant or is otherwise separately identifiable.
Notwithstanding any contrary provision of this Article XVIII, Landlord and
Tenant shall each be entitled to receive 50% of the "bonus value" of the
leasehold estate in connection therewith, which bonus value shall be equal to
the difference between the Rent payable under this Lease and the sum established
by the condemning authority as the award for compensation. Tenant hereby waive
any and all rights it might otherwise have pursuant to Section 1265.130 of the
California Code of Civil Procedure, or any similar or successor Laws.

XIX.  EVENTS OF DEFAULT.

      Tenant shall be considered to be in default of this Lease upon the
occurrence of any of the following events of default:

      A.    Tenant's failure to pay when due all or any portion of the Rent, if
            the failure continues for 5 days after written notice to Tenant
            ("Monetary Default").

                                      -25-
<PAGE>

      B.    Tenant's failure (other than a Monetary Default) to comply with any
            term, provision or covenant of this Lease, if the failure is not
            cured within 30 days after written notice to Tenant. However, if
            Tenant's failure to comply cannot reasonably be cured within 30
            days, Tenant shall be allowed additional time (not to exceed 90
            days) as is reasonably necessary to cure the failure so long as: (1)
            Tenant commences to cure the failure within 30 days, and (2) Tenant
            diligently pursues a course of action that will cure the failure and
            bring Tenant back into compliance with the Lease. However, if
            Tenant's failure to comply creates a hazardous condition, the
            failure must be cured immediately upon notice to Tenant.

      C.    A petition is filed by or against Tenant under the United States
            Bankruptcy Code or any other federal or state laws governing
            insolvency (and, in the case of a petition filed against Tenant, the
            same is not discharged within 30 days), or Tenant makes a transfer
            in fraud of creditors or makes an assignment for the benefit of
            creditors, or admits in writing its inability to pay its debts when
            due.

      D.    The leasehold estate is taken by process or operation of Law, and
            such taking is not stayed or dismissed within 30 days.

XX.   REMEDIES.

      A.    Upon the occurrence of any event or events of default under this
            Lease, whether enumerated in Article XIX or not, Landlord shall have
            the option to pursue any one or more of the following remedies
            without any notice (except as expressly prescribed herein) or demand
            whatsoever (and without limiting the generality of the foregoing,
            Tenant hereby specifically waives notice and demand for payment of
            Rent or other obligations, except for those notices specifically
            required pursuant to the terms of Article XIX or this Article XX,
            and waives any and all other notices or demand requirements imposed
            by applicable law):

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

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

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

                  (c)   The Worth at the Time of Award of the amount by which
                        the unpaid Rent for the balance of the Term after the
                        time of award

                                      -26-
<PAGE>

                        exceeds the amount of such Rent loss that Tenant
                        affirmatively proves could be reasonably avoided;

                  (d)   Any other amount necessary to compensate Landlord for
                        all the detriment either proximately caused by Tenant's
                        failure to perform Tenant's obligations under this Lease
                        or which in the ordinary course of things would be
                        likely to result therefrom; and

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

                  The "Worth at the Time of Award" of the amounts referred to in
                  parts (a) and (b) above, shall be computed by allowing
                  interest at the lesser of a per annum rate equal to: (i) the
                  greatest per annum rate of interest permitted from time to
                  time under applicable law, or (ii) the Prime Rate plus 4%. For
                  purposes hereof and of Section XX.D below, the "Prime Rate"
                  shall be the Prime Rate from time to time published in the
                  Money Rates column of The Wall Street Journal; provided,
                  however, if The Wall Street Journal ceases to publish the
                  Prime Rate in its Money Rates column or similar section of The
                  Wall Street Journal, the "Prime Rate" shall be the per annum
                  interest rate publicly announced as its prime or base rate by
                  a federally insured bank selected by Landlord in the state in
                  which the Building is located. The "Worth at the Time of
                  Award" of the amount referred to in part (c), above, shall be
                  computed by discounting such amount at the discount rate of
                  the Federal Reserve Bank of San Francisco at the time of award
                  plus 1%;

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

            3.    Notwithstanding Landlord's exercise of the remedy described in
                  California Civil Code Section 1951.4 in respect of an event or
                  events of default, at such time thereafter as Landlord may
                  elect in writing, to terminate this Lease and Tenant's right
                  to possession of the Premises and recover an award of damages
                  as provided above in Paragraph XX.A.1.

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

                                      -27-

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

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

      E.    If Tenant is in default, then, to the extent permitted by Law,
            Landlord shall be entitled to receive interest on any unpaid item of
            Rent at a rate equal to the lesser of the maximum rate permitted by
            Law or the Prime Rate plus 3% per annum.

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

XXI.  LIMITATION OF LIABILITY.

      NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS LEASE, THE
LIABILITY OF LANDLORD (AND OF ANY SUCCESSOR LANDLORD) TO TENANT SHALL BE LIMITED
TO THE INTEREST OF LANDLORD IN THE PROPERTY. TENANT SHALL LOOK SOLELY TO
LANDLORD'S INTEREST IN THE PROPERTY FOR THE RECOVERY OF ANY JUDGMENT OR AWARD
AGAINST LANDLORD. NEITHER LANDLORD NOR ANY LANDLORD RELATED PARTY SHALL BE
PERSONALLY LIABLE FOR ANY JUDGMENT OR DEFICIENCY. BEFORE FILING SUIT FOR AN
ALLEGED DEFAULT BY LANDLORD, TENANT SHALL GIVE LANDLORD AND THE MORTGAGEE(S)
(DEFINED IN ARTICLE XXVI BELOW) WHOM TENANT HAS BEEN NOTIFIED HOLD MORTGAGES
(DEFINED IN ARTICLE XXVI BELOW) ON THE PROPERTY, BUILDING OR PREMISES, NOTICE
AND REASONABLE TIME TO CURE THE ALLEGED DEFAULT. FOR PURPOSES HEREOF, "INTEREST
OF LANDLORD IN

                                      -28-
<PAGE>

THE PROPERTY" SHALL INCLUDE RENTS DUE FROM TENANTS, INSURANCE PROCEEDS, AND
PROCEEDS FROM CONDEMNATION OR EMINENT DOMAIN PROCEEDINGS (PRIOR TO THE
DISTRIBUTION OF SAME TO ANY PARTNER OR SHAREHOLDER OF LANDLORD OR ANY OTHER
THIRD PARTY).

XXII. NO WAIVER.

      Either party's failure to declare a default immediately upon its
occurrence, or delay in taking action for a default shall not constitute a
waiver of the default, nor shall it constitute an estoppel. Either party's
failure to enforce its rights for a default shall not constitute a waiver of its
rights regarding any subsequent default. Receipt by Landlord of Tenant's keys to
the Premises shall not constitute an acceptance or surrender of the Premises.

XXIII. QUIET ENJOYMENT.

      Tenant shall, and may quietly and peacefully have, hold and enjoy the
Premises, subject to the terms of this Lease, provided Tenant pays the Rent and
fully performs all of its covenants and agreements. This covenant and all other
covenants of Landlord shall be binding upon Landlord and its successors only
during its or their respective periods of ownership of the Building, and shall
not be a personal covenant of Landlord or the Landlord Related Parties.

XXIV. INTENTIONALLY OMITTED.

XXV.  HOLDING OVER.

      Except for any permitted occupancy by Tenant under Article VIII, if Tenant
fails to surrender the Premises at the expiration or earlier termination of this
Lease, occupancy of the Premises after the termination or expiration shall be
that of a tenancy at sufferance. During the first 15 days of any such holdover,
Tenant shall pay an amount equal to 125% of the sum of the Base Rent and
Additional Rent due for the period immediately preceding the holdover,
calculated and payable on a per day basis for each day in such initial 15 day
period that Tenant holds over in the Premises. Thereafter, commencing on the
16th day of any such holdover, Tenant shall pay an amount (on a per calendar
month basis without reduction for partial calendar months during the remainder
of the holdover) equal to 125% of the greater of: (1) the sum of the Base Rent
and Additional Rent due for the period immediately preceding the holdover; or
(2) the fair market gross rental for the Premises as reasonably determined by
Landlord. No holdover by Tenant or payment by Tenant after the expiration or
early termination of this Lease shall be construed to extend the Term or prevent
Landlord from immediate recovery of possession of the Premises by summary
proceedings or otherwise. In addition to the payment of the amounts provided
above, if Landlord is unable to deliver possession of the Premises to a new
tenant, or to perform improvements for a new tenant, as a result of Tenant's
holdover and Tenant fails to vacate the Premises within 15 days after Landlord
notifies Tenant of Landlord's inability to deliver possession, or perform
improvements, Tenant shall be liable to Landlord for all damages, including,
without limitation, consequential damages, that Landlord suffers from the
holdover.

XXVI. SUBORDINATION TO MORTGAGES; ESTOPPEL CERTIFICATE.

      A.    Tenant accepts this Lease subject and subordinate to any
            mortgage(s), deed(s) of trust, ground lease(s) or other lien(s) now
            or subsequently arising upon the Premises, the Building or the
            Property, and to renewals, modifications, refinancings and
            extensions thereof (collectively referred to as a "Mortgage"). The
            party having the benefit of a Mortgage shall be referred to as a
            "Mortgagee". This clause shall be self-operative, but upon request
            from a Mortgagee, Tenant shall execute a commercially reasonable
            subordination agreement in favor of the Mortgagee. In lieu of having
            the Mortgage be superior to this Lease, a Mortgagee shall have the
            right at any time to subordinate its Mortgage to this Lease. If
            requested by a successor-in-interest to all or a part of Landlord's
            interest in the Lease, Tenant shall, without charge, attorn to the
            successor-in-interest. Notwithstanding the foregoing in this Section
            to the contrary, as a condition precedent to the future
            subordination of this Lease to a future Mortgage, Landlord shall be
            required to provide Tenant with a non-disturbance, subordination,
            and attornment agreement in favor of Tenant from any Mortgagee who
            comes into existence after the Commencement Date. Such
            non-disturbance, subordination, and attornment agreement in favor of
            Tenant shall provide that, so long as Tenant is paying the Rent due
            under the Lease and is not otherwise in default under the Lease
            beyond any applicable cure period, its right to possession and the
            other terms of the Lease shall remain in full force and effect. Such
            non-disturbance, subordination, and attornment agreement may include
            other commercially reasonable provisions in favor of the Mortgagee,
            including, without limitation, additional time on behalf of the
            Mortgagee to cure defaults of the Landlord to provide that (a)
            neither Mortgagee nor any successor-in-interest shall be bound by
            (i) any payment of the Base Rent, Additional Rent, or other sum due
            under this Lease for more than 1 month in advance or (ii) any
            amendment or modification of the Lease made without the express
            written consent of Mortgagee or any successor-in-interest; (b)
            neither Mortgagee nor any successor-in-interest will be liable for
            (i) any act or omission or warranties of any prior landlord
            (including Landlord), (ii) the breach of any warranties or
            obligations relating to construction of improvements on the Property
            or any tenant finish work performed or to have been performed by any
            prior landlord (including Landlord), or (iii) the return of any
            security deposit, except to the extent such deposits have been
            received by Mortgagee; and (c) neither Mortgagee nor any
            successor-in-interest shall be subject to any offsets or defenses
            which Tenant might have against any prior landlord (including
            Landlord).

      B.    Landlord and Tenant shall each, within 10 Business Days after
            receipt of a written request from the other, execute and deliver an
            estoppel certificate to those parties as are reasonably requested by
            the other (including a Mortgagee or prospective purchaser). The
            estoppel certificate shall include a statement certifying that this
            Lease is unmodified (except as identified in the estoppel
            certificate) and in full force and effect, describing the dates to
            which Rent and other charges have been paid, representing that, to
            such party's actual knowledge, there is no default (or

                                      -30-
<PAGE>

stating the nature of the alleged default) and indicating other matters with
respect to the Lease that may reasonably be requested.

XXVII. ATTORNEYS' FEES.

      If either party institutes a suit against the other for violation of or to
enforce any covenant or condition of this Lease, or if either party intervenes
in any suit in which the other is a party to enforce or protect its interest or
rights, the prevailing party shall be entitled to all of its costs and expenses,
including, without limitation, reasonable attorneys' fees.

XXVIII. NOTICE.

      If a demand, request, approval, consent or notice (collectively referred
to as a "notice") shall or may be given to either party by the other, the notice
shall be in writing and delivered by hand or sent by registered or certified
mail with return receipt requested, or sent by nationally recognized overnight
or same day courier service at the party's respective Notice Address(es) set
forth in Article I, except that if Tenant has vacated the Premises (or if the
Notice Address for Tenant is other than the Premises, and Tenant has vacated
such address) without providing Landlord a new Notice Address, Landlord may
serve notice in any manner described in this Article or in any other manner
permitted by Law. Each notice shall be deemed to have been received or given on
the earlier to occur of actual delivery or the date on which delivery is
refused, or, if Tenant has vacated the Premises or the other Notice Address of
Tenant without providing a new Notice Address, 3 days after notice is deposited
in the U.S. mail or with a courier service in the manner described above. Either
party may, at any time, change its Notice Address (other than to a post office
box address) by giving the other party written notice of the new address in the
manner described in this Article.

XXIX. EXCEPTED RIGHTS.

      This Lease does not grant any rights to light or air over or about the
Building. Landlord excepts and reserves exclusively to itself the use of: (1)
roofs, (2) telephone, electrical and janitorial closets, (3) equipment rooms,
Building risers or similar areas that are used by Landlord for the provision of
Building services, (4) rights to the land and improvements below the floor of
the Premises, (5) the improvements and air rights above the Premises, (6) the
improvements and air rights outside the demising walls of the Premises, and (7)
the areas within the Premises used for the installation of utility lines and
other installations serving occupants of the Building. Landlord has the right to
change the Building's name or address. Landlord also has the right to make such
other changes to the Property and Building as Landlord deems appropriate,
provided the changes do not materially affect Tenant's ability to use the
Premises for the Permitted Use. Landlord shall also have the right (but not the
obligation) to temporarily close the Building if Landlord reasonably determines
that there is an imminent danger of significant damage to the Building or of
personal injury to the employees or the occupants of the Building. The
circumstances under which Landlord may temporarily close the Building shall
include, without limitation, electrical interruptions, hurricanes and civil
disturbances. A closure of the Building under such circumstances shall not
constitute a constructive eviction nor entitle Tenant to an abatement or
reduction of Rent, provided, however, Tenant shall be entitled to an abatement
of

                                      -31-
<PAGE>

Rent in accordance with Section VIII.B if the Building is closed, other than as
required by Law or by order of proper governmental authority, and Tenant is
unable to use the Premises as a result of such closure, for a period of at least
3 consecutive Business Days.

XXX.  SURRENDER OF PREMISES.

      At the expiration or earlier termination of this Lease or Tenant's right
of possession, Tenant shall remove Tenant's Property (defined in Article XV)
from the Premises, and quit and surrender the Premises to Landlord, broom clean,
and in good order, condition and repair, ordinary wear and tear excepted. Tenant
shall also be required to remove the Required Removables in accordance with
Article VIII. If Tenant fails to remove any of Tenant's Property within 2 days
after the termination of this Lease or of Tenant's right to possession,
Landlord, at Tenant's sole cost and expense, shall be entitled (but not
obligated) to remove and store Tenant's Property. Landlord shall not be
responsible for the value, preservation or safekeeping of Tenant's Property.
Tenant shall pay Landlord, upon demand, the expenses and storage charges
incurred for Tenant's Property. In addition, if Tenant fails to remove Tenant's
Property from the Premises or storage, as the case may be, within 30 days after
written notice, Landlord may deem all or any part of Tenant's Property to be
abandoned, and title to Tenant's Property shall be deemed to be immediately
vested in Landlord.

XXXI. MISCELLANEOUS.

      A.    This Lease and the rights and obligations of the parties shall be
            interpreted, construed and enforced in accordance with the Laws of
            the State of California and Landlord and Tenant hereby irrevocably
            consent to the jurisdiction and proper venue of such state. If any
            term or provision of this Lease shall to any extent be invalid or
            unenforceable, the remainder of this Lease shall not be affected,
            and each provision of this Lease shall be valid and enforced to the
            fullest extent permitted by Law. The headings and titles to the
            Articles and Sections of this Lease are for convenience only and
            shall have no effect on the interpretation of any part of the Lease.

      B.    Tenant shall not record this Lease or any memorandum without
            Landlord's prior written consent.

      C.    Landlord and Tenant hereby waive any right to trial by jury in any
            proceeding based upon a breach of this Lease.

      D.    Whenever a period of time is prescribed for the taking of an action
            by Landlord or Tenant, the period of time for the performance of
            such action shall be extended by the number of days that the
            performance is actually delayed due to strikes, acts of God,
            shortages of labor or materials, war, civil disturbances and other
            causes beyond the reasonable control of the performing party ("Force
            Majeure"). However, events of Force Majeure shall not extend any
            period of time for the payment of Rent or other sums payable by
            either party or any period of time for the written exercise of an
            option or right by either party.

                                      -32-
<PAGE>

      E.    Landlord shall have the right to transfer and assign, in whole or in
            part, all of its rights and obligations under this Lease and in the
            Building and/or Property referred to herein, and upon such transfer
            Landlord shall be released from any further obligations hereunder,
            and Tenant agrees to look solely to the successor in interest of
            Landlord for the performance of such obligations.

      F.    Tenant shall indemnify and hold Landlord and the Landlord Related
            Parties harmless from all claims of any brokers claiming to have
            represented Tenant in connection with this Lease. Landlord agrees to
            indemnify and hold Tenant and the Tenant Related Parties harmless
            from all claims of any brokers claiming to have represented Landlord
            in connection with this Lease.

            Equity Office Properties Management Corp. ("EOPMC") is an affiliate
            of Landlord and represents only the Landlord in this transaction.
            Any assistance rendered by any agent or employee of EOPMC in
            connection with this Lease or any subsequent amendment or
            modification hereto has been or will be made as an accommodation to
            Tenant solely in furtherance of consummating the transaction on
            behalf of Landlord, and not as agent for Tenant.

      G.    Tenant covenants, warrants and represents that: (1) each individual
            executing, attesting and/or delivering this Lease on behalf of
            Tenant is authorized to do so on behalf of Tenant; (2) this Lease is
            binding upon Tenant; and (3) Tenant is duly organized and legally
            existing in the state of its organization and is qualified to do
            business in the State of California. Landlord covenants, warrants
            and represents that: (1) each individual executing, attesting and/or
            delivering this Lease on behalf of Landlord is authorized to do so
            on behalf of Landlord; (2) this Lease is binding upon Landlord; and
            (3) Landlord is duly organized and legally existing in the state of
            its organization and is qualified to do business in the state in
            which the Premises are located.

      H.    Time is of the essence with respect to each provision of this Lease
            in which time is an element. This Lease shall create only the
            relationship of landlord and tenant between the parties, and not a
            partnership, joint venture or any other relationship. This Lease and
            the covenants and conditions in this Lease shall inure only to the
            benefit of and be binding only upon Landlord and Tenant and their
            permitted successors and assigns.

      I.    The expiration of the Term, whether by lapse of time or otherwise,
            shall not relieve either party of any obligations which accrued
            prior to or which may continue to accrue after the expiration or
            early termination of this Lease. Without limiting the scope of the
            prior sentence, it is agreed that Tenant's obligations under
            Articles IV, VIII, XIV, XX, XXV and XXX shall survive the expiration
            or early termination of this Lease.

      J.    Landlord has delivered a copy of this Lease to Tenant for Tenant's
            review only, and the delivery of it does not constitute an offer to
            Tenant or an option. This Lease shall not be effective against any
            party hereto until an original copy of this Lease has been signed by
            such party.

      K.    All understandings and agreements previously made between the
            parties are superseded by this Lease, and neither party is relying
            upon any warranty, statement or representation not contained in this
            Lease. This Lease may be modified only by a written agreement signed
            by Landlord and Tenant.

      L.    Tenant, within 15 days after request, shall provide Landlord with a
            current financial statement and such other information as Landlord
            may reasonably request in order to create a "business profile" of
            Tenant and determine Tenant's ability to fulfill its obligations
            under this Lease. Landlord, however, shall not require Tenant to
            provide such information unless Landlord is requested to produce the
            information in connection with a proposed financing or sale of the
            Building. Upon written request by Tenant, Landlord shall enter into
            a commercially reasonable confidentiality agreement covering any
            confidential information that is disclosed by Tenant. However,
            nothing in this Lease shall be construed to obligate Tenant to share
            with Landlord or any actual or prospective Mortgagee any non-public
            information concerning Tenant or Tenant's financial condition or
            business affairs. The parties agree that this Section XXXI.L shall
            not apply so long as Tenant is a public company and in material
            compliance with the financial reporting requirements imposed by the
            Securities and Exchange Commission. This Lease shall be subject and
            subordinate to, and Tenant agrees to perform and comply with, the
            terms, conditions and provisions of all documents of record now or
            hereafter entered into affecting the Building and the Property.

      M.    Except (i) for matters for which there is a standard of consent or
            discretion specifically set forth in this Lease; (ii) matters which
            could have an adverse effect on the Building structure or the
            systems and equipment of the Building, or which could affect the
            exterior appearance of the Building, or which affect signage, or
            which relate to costs of removal, or (iii) matters covered by
            Article IV (Rent), Article XV (Insurance), Article XIX (Events of
            Default), or Article XX (Remedies) of this Lease (collectively, the
            "Excepted Matters"), any time the consent of Landlord or Tenant is
            required under this Lease, such consent shall not be unreasonably
            withheld or delayed, and, except with regard to the Excepted
            Matters, whenever this Lease grants Landlord or Tenant the right to
            take action, exercise discretion, establish rules and regulations or
            make an allocation or other determination, Landlord and Tenant shall
            act reasonably and in good faith.

      N.    Notwithstanding anything to the contrary set forth in this Lease,
            Landlord shall be in default in the performance of any obligation
            required to be performed by Landlord pursuant to this Lease if
            Landlord fails to perform such obligation within 30 days after the
            receipt of notice from Tenant specifying in detail

                                      -34-
<PAGE>

            Landlord's failure to perform; provided, however, if the nature of
            Landlord's obligation is such that more than 30 days are required
            for its performance, then Landlord shall not be in default under
            this Lease if it shall commence such performance within such 30 day
            period and thereafter diligently pursue the same to completion. Upon
            any such default by Landlord under this Lease, Tenant may, except as
            otherwise specifically provided in this Lease to the contrary,
            exercise any of its rights provided at law or in equity. No right or
            remedy herein conferred upon or reserved to Tenant is intended to be
            exclusive of any other right or remedy, and each and every right and
            remedy shall be cumulative and in addition to any other right or
            remedy given hereunder or now or hereafter existing by agreement,
            applicable law or in equity. In addition to other remedies provided
            in this Lease, Tenant shall be entitled, to the extent permitted by
            applicable law, to injunctive relief, or to a decree compelling
            performance of any of the covenants, agreements, conditions or
            provisions of this Lease, or to any other remedy allowed to Tenant
            at law or in equity. Forbearance by Tenant to enforce one or more of
            the remedies herein provided upon an event of default shall not be
            deemed or construed to constitute a waiver of such default.

XXXII. ENTIRE AGREEMENT.

      This Lease, including the following exhibits and attachments which are
hereby incorporated into and made a part of this Lease, constitute the entire

understandings related to the Premises, including all lease proposals, letters

                  Notice") not less than 12 full calendar months prior to the
                  expiration of the initial Term or the expiration of the First
                  Option Term, as applicable; and

            2.    Tenant is not in Monetary Default or material non-Monetary
                  Default under the Lease beyond any applicable cure periods at
                  the time that Tenant delivers the applicable Initial Renewal
                  Notice or at the time Tenant delivers the applicable Binding
                  Notice (as defined below); and

            3.    No more than 25% of the Rentable Square Footage of the
                  Premises in the aggregate is sublet (other than pursuant to a
                  Permitted Transfer, as defined in Article XII of the lease) at
                  the time that Tenant delivers the applicable Initial Renewal
                  Notice or at the time Tenant delivers the applicable Binding
                  Notice.

      B.    Terms Applicable to Premises During the First Option Term and the
            Second Option Term.

            1.    The initial Base Rent rate per rentable square foot for the
                  Premises during the First Option Term and the Second Option
                  Term, as applicable, shall equal ninety-five percent (95%) of
                  the Prevailing Market (hereinafter defined) rate per rentable
                  square foot for the Premises. Base Rent during the First
                  Option Term or the Second Option Term, as the case may be,
                  shall increase, if at all, in accordance with the increases
                  assumed in the determination of Prevailing Market rate. Base
                  Rent attributable to the

                                    EXHIBIT E
                                       -1-
<PAGE>

                  Premises shall be payable in monthly installments in
                  accordance with the terms and conditions of Article IV of the
                  Lease.

            2.    Tenant shall pay Additional Rent (i.e. Taxes and Expenses) for
                  the Premises during the First Option Term and the Second
                  Option Term in accordance with Article IV of the Lease, and
                  the manner and method in which Tenant reimburses Landlord for
                  Tenant's share of Taxes and Expenses and the Base Year, if
                  any, applicable to such matter, shall be some of the factors
                  considered in determining the Prevailing Market rate for the
                  First Option Term or the Second Option Term, as the case may
                  be.

            3.    The parking rate for Tenant's Parking Rights (defined in
                  Section III.A of this Exhibit E) during the First Option Term
                  and the Second Option Term, as applicable, shall equal the
                  Prevailing Market for Parking (hereinafter defined) rate.

            4.    Landlord shall not be obligated to pay any brokerage
                  commission in connection with any broker representing, or
                  claiming to represent, Tenant in connection with either of the
                  Options.

      C.    Procedure for Determining Prevailing Market and Prevailing Market
            for Parking. Within 30 days after receipt of Tenant's Initial
            Renewal Notice (but no sooner than the first day of the 14th full
            calendar month prior to the expiration of the initial Term or the
            expiration of the First Option Term, as applicable, Landlord shall
            advise Tenant of the applicable Base Rent rate for the Premises and
            the parking rate for the applicable Option Term. Tenant, within 15
            days after the date on which Landlord advises Tenant of the
            applicable Base Rent rate and parking rate for the applicable Option
            Term, shall either (i) give Landlord final binding written notice
            ("Binding Notice") of Tenant's exercise of its option, or (ii) if
            Tenant disagrees with Landlord's determination, provide Landlord
            with written notice of rejection (the "Rejection Notice"). If Tenant
            fails to provide Landlord with either a Binding Notice or Rejection
            Notice within such 15 day period, Tenant shall be deemed to have
            delivered a Rejection Notice. If Tenant provides Landlord with a
            Binding Notice, Landlord and Tenant shall enter into the Renewal
            Amendment upon the terms and conditions set forth herein. If Tenant
            provides (or is deemed to have provided) Landlord with a Rejection
            Notice, Landlord and Tenant shall work together in good faith to
            agree upon the Prevailing Market rate for the Premises and the
            Prevailing Market for Parking rate during the applicable Option
            Term. Upon agreement Tenant shall provide Landlord with Binding
            Notice and Landlord and Tenant shall enter into the Renewal
            Amendment in accordance with the terms and conditions hereof.
            Notwithstanding the foregoing, if Landlord and Tenant are unable to
            agree upon the Prevailing Market rate for the Premises and/or the
            Prevailing Market for Parking rate within 30 days after the date on
            which Tenant provides (or is deemed to have provided) Landlord with
            a Rejection Notice, either party, by written notice to the other
            (the "Arbitration Notice") within 5 Business Days after the

                                    EXHIBIT E
                                       -2-
<PAGE>

            expiration of such 30 day period, shall have the right to have the
            Prevailing Market rate and/or the Prevailing Market for Parking rate
            determined in accordance with the following procedures. If neither
            party exercises its right to arbitrate, the Option and any
            subsequent Options shall be deemed to be null and void and of no
            further force and effect. If either party timely provides the other
            with an Arbitration Notice, Landlord and Tenant, within 10 days
            after the date of the Arbitration Notice, shall each simultaneously
            submit to the other, in a sealed envelope, its good faith estimate
            of the Prevailing Market rate (collectively referred to as the
            "Estimates"). If the higher of such Estimates is not more than 105%
            of the lower of such Estimates, the Prevailing Market rate shall be
            the average of the two Estimates. The foregoing procedure shall also
            be used with respect to the determination of the Prevailing Market
            for Parking rate. If the Prevailing Market rate and/or the
            Prevailing Market for Parking rate is not resolved by the exchange
            of Estimates, Landlord and Tenant, within 10 days after the exchange
            of Estimates, shall each select an appraiser to determine which of
            the two applicable Estimates most closely reflects the Prevailing
            Market rate for the Premises and/or the Prevailing Market for
            Parking rate. Each appraiser so selected shall be certified as an
            MAI appraiser or as an ASA appraiser and shall have had at least 5
            years experience within the previous 10 years as a real estate
            appraiser working in the vicinity with working knowledge of current
            rental rates and practices. For purposes of this Lease, an "MAI"
            appraiser means an individual who holds an MAI designation conferred
            by, and is an independent member of, the American Institute of Real
            Estate Appraisers (or its successor organization, or in the event
            there is no successor organization, the organization and designation
            most similar), and an "ASA" appraiser means an individual who holds
            the Senior Member designation conferred by, and is an independent
            member of, the American Society of Appraisers (or its successor
            organization, or, in the event there is no successor organization,
            the organization and designation most similar). Upon selection,
            Landlord's and Tenant's appraisers shall work together in good faith
            to agree upon which of the two Estimates most closely reflects the
            Prevailing Market rate for the Premises and/or the Prevailing Market
            for Parking rate, as applicable. The applicable Estimate chosen by
            such appraisers shall be binding on both Landlord and Tenant as the
            Prevailing Market rate and/or the Prevailing Market for Parking rate
            for the Option Term, as applicable. If either Landlord or Tenant
            fails to appoint an appraiser within the 10 day period referred to
            above, the appraiser appointed by the other party shall be the sole
            appraiser for the purposes hereof. If the two appraisers cannot
            agree upon which of the two applicable Estimates most closely
            reflects the Prevailing Market and/or the Prevailing Market for
            Parking rate, as applicable, within the 20 days after their
            appointment, then, within 10 days after the expiration of such 20
            day period, the 2 appraisers shall select a third appraiser meeting
            the aforementioned criteria. Once the third appraiser has been
            selected as provided for above, then, as soon thereafter as
            practicable but in any case within 14 days, the third appraiser
            shall make his determination of which of the two applicable
            Estimates most closely reflects the Prevailing Market rate and/or
            the Prevailing Market for Parking rate, as applicable, and such
            Estimate shall be binding on both

                                    EXHIBIT E
                                       -3-
<PAGE>

            Landlord and Tenant as the Prevailing Market rate and/or the
            Prevailing Market for Parking rate, as applicable, for the Option
            Term. If the arbitrator believes that expert advice would materially
            assist him, he may retain one or more qualified persons, provided
            they have had no dealings with Landlord or Tenant within the
            immediately preceding 12 month period, to provide such expert
            advice. The parties shall share equally in the costs of the
            arbitrator and of any experts reasonably retained by the arbitrator.
            Any fees of any appraiser, counsel or experts engaged directly by
            Landlord or Tenant, however, shall be borne by the party retaining
            such appraiser, counsel or expert. In the event that the Prevailing
            Market rate and/or the Prevailing Market for Parking rate has not
            been determined by the commencement date of the applicable Option
            Term, Tenant shall pay Base Rent and the parking rate upon the terms
            and conditions in effect for the Premises until such time as the
            Prevailing Market rate and/or the Prevailing Market for parking
            rate, as applicable, has been determined. Upon such determination,
            the Base Rent for the Premises and the parking rate for Tenant's
            Parking Rights shall be retroactively adjusted, if necessary, to the
            commencement of the applicable Option Term. If such adjustment
            results in an underpayment of Base Rent and/or parking charges by
            Tenant, Tenant shall pay Landlord the amount of such underpayment
            within 30 days after the determination thereof. If such adjustment
            results in an overpayment of Base Rent and/or parking charges by
            Tenant, Landlord shall credit such overpayment against the next
            installment of Base Rent or parking charges, as applicable, due
            under the Lease and, to the extent necessary, any subsequent
            installments until the entire amount of such overpayment has been
            credited against Base Rent or parking charges, as applicable, or at
            Tenant's election, reimburse Tenant within 30 days.

      D.    Renewal Amendment. If Tenant is entitled to and properly exercises
            its applicable Option, Landlord shall prepare an amendment (the
            "Renewal Amendment") to reflect changes in the Base Rent, Term,
            Termination Date, parking charges, and other appropriate terms. The
            Renewal Amendment shall be sent to Tenant (and thereafter executed
            and returned by Tenant) within a reasonable time after final
            determination of the Prevailing Market rate applicable during the
            First Option Term or the Second Option Term, as applicable. An
            otherwise valid exercise of the applicable Option shall be fully
            effective whether or not the Renewal Amendment is executed.

      E.    Definition of Prevailing Market. For purposes of the Options,
            "Prevailing Market" shall mean the arms length fair market annual
            rental rate per rentable square foot under renewal leases and
            amendments entered into on or about the date on which the Prevailing
            Market is being determined hereunder for space comparable to the
            Premises in the Building and office buildings comparable to the
            Building in the Foster City, California area (the "Comparable
            Buildings"). The determination of Prevailing Market shall take into
            account all relevant factors in determining the current fair market
            rental rate for premises comparable to the Premises located in the
            Building and the Comparable Buildings, fully recognizing any
            material economic differences (but in any event disregarding the
            presence or

            absence of brokerage commissions) between the terms of this Lease
            and any comparison lease or amendment, including, without
            limitation: (1) the creditworthiness of the tenant, (2) the size,
            configuration and location of the leased premises (including rights
            to expand or contract), (3) the presence or absence of parking,
            views and other amenities serving the leased premises, (4) the term
            of the letting (including options to extend or shorten the term),
            (5) the condition of the leased premises and any improvement
            allowances or construction obligations of the landlord pertaining
            thereto, (5) the manner, if any, in which the landlord is reimbursed
            or otherwise compensated for operating expenses and taxes, (6) any
            periods of free or abated rent, and (7) any other material
            concessions, inducements or consideration to be paid to or received
            by either the landlord or the tenant in connection with the lease in
            question. The determination of Prevailing Market shall also take
            into consideration any reasonably anticipated changes in the
            Prevailing Market rate from the time such Prevailing Market rate is
            being determined and the time such Prevailing Market rate will
            become effective under this Lease.

      F.    Definition of Prevailing Market for Parking. For purposes of the
            Options, "Prevailing Market for Parking" shall mean the arms length
            fair market parking rate under renewal leases and amendments entered
            into on or about the date on which the Prevailing Market for Parking
            is being determined hereunder for space comparable to the Premises
            in the Building and the Comparable Buildings. The determination of
            Prevailing Market for Parking shall take into account all relevant
            factors in determining the current fair market parking rate for
            premises comparable to the Premises located in the Building and in
            Comparable Buildings, such as: (1) the creditworthiness of the
            tenant, (2) the size of the leased premises (including rights to
            expand or contract), and (3) the term of the letting (including
            options to extend or shorten the term). The determination of
            Prevailing Market for Parking shall also take into consideration any
            reasonably anticipated changes in the Prevailing Market for Parking
            rate from the time such Prevailing Market for Parking rate is being
            determined and the time such Prevailing Market for Parking rate will
            become effective under this Lease.

II.   RIGHT OF FIRST OFFER.

      A.    Grant of Right of First Offer. During the initial Term and the
            Option Terms, Tenant shall have, subject to the provisions of this
            Section II, a right of first offer to lease any space in the 4000
            Building (other than the 4th floor thereof) (the "First Offer
            Space") if such space becomes available for lease as provided
            hereinbelow. Tenant's right of first offer shall be upon the terms
            and conditions set forth in this Section II and shall be a one-time
            right of first offer with respect to every portion, and all of the
            square footage, of the First Offer Space which is offered to Tenant
            for lease as set forth in this Section II. In the event that Tenant
            elects not to lease, as set forth in Section II.C, below, the
            particular First Offer Space offered to Tenant by Landlord, Tenant's
            right of first offer with respect to that particular First Offer
            Space shall terminate and Tenant will no longer have a right of
            first

                                    EXHIBIT E
                                       -5-
<PAGE>

            offer to lease that particular First Offer Space. Notwithstanding
            anything to the contrary contained in this Section II, Tenant's
            right of first offer contained in this Section II shall be subject
            and subordinate to any rights of any existing tenant of the Building
            as of the Commencement Date to lease the First Offer Space, or any
            portion thereof (whether pursuant to must-take rights, expansion
            rights, rights of first refusal, first offer rights, or other
            similar rights), and irrespective of whether the exercise of any
            such right is consummated pursuant to a lease amendment or a new
            lease (the "Superior Rights"), and Tenant shall not have any such
            first offer right to lease any First Offer Space until after such
            First Offer Space becomes available for lease following the
            expiration or earlier termination of the lease of the tenant in
            existence as of the Commencement Date as to such First Offer Space,
            including renewals thereof (whether or not such renewal is pursuant
            to an express written provision in such lease and regardless of
            whether any such renewal is consummated pursuant to a new lease or
            lease amendment) and the tenant thereunder has vacated such First
            Offer Space. Notwithstanding any contrary provision of this Section
            II, Landlord shall not be obligated to pay any brokerage commission
            in connection with any broker representing, or claiming to
            represent, Tenant in connection with Tenant's right of first offer
            hereunder.

      B.    Procedure for Offer. Landlord shall give Tenant written notice (the
            "First Offer Notice") that the First Offer Space shall or has become
            available for lease by Tenant pursuant to the terms of Tenant's
            right of first offer, as set forth in this Section II, provided that
            no holder of the Superior Rights desires to lease all or any portion
            of such space. Pursuant to such First Offer Notice, Landlord shall
            offer to lease to Tenant the then available First Offer Space for a
            term coterminous with the Term. The First Offer Notice shall
            describe the space so offered to Tenant, including, without
            limitation, Landlord's determination of the rentable square footage
            thereof, and shall also set forth Landlord's determination of the
            First Offer Rent, (defined in Section II.D below), and the other
            terms upon which Landlord is willing to lease such space to Tenant.
            After Landlord delivers the First Offer Notice to Tenant, Tenant may
            submit a written request to Landlord for access to the First Offer
            Space to view the First Offer Space. After receiving any such
            written notice from Tenant, Landlord shall use commercially
            reasonable efforts to arrange a mutually convenient time for Tenant
            and a representative of Landlord to walk through the First Offer
            Space.

      C.    Procedure for Acceptance. If Tenant wishes to exercise Tenant's
            right of first offer with respect to the space described in the
            First Offer Notice, then within 10 days of Tenant's receipt of the
            First Offer Notice, Tenant shall deliver written notice to Landlord
            ("Tenant's Election Notice") pursuant to which Tenant shall elect
            either to: (i) lease the entire First Offer Space described in the
            First Offer Notice at the First Offer Rent and upon the terms
            contained in such notice; or (ii) refuse to lease the First Offer
            Space, specifying that Tenant is not interested in exercising its
            right of first offer for the First Offer Space, in which event
            Tenant's right of first offer with respect to the First Offer Space
            described in the First Offer Notice shall terminate and be of no
            further force or effect and Landlord shall be

            free to lease such First Offer Space or any portion thereof to
            anyone to whom Landlord desires on any terms Landlord desires. If
            Tenant does not timely notify Landlord of its election of either of
            the options in clauses (i) or (ii) hereinabove, Tenant shall be
            deemed to have elected the option in clause (ii).

      D.    First Offer Rent. The Base Rent payable by Tenant for the First
            Offer Space (the "First Offer Rent") shall be equal to the greater
            of (i) the Base Rent rate per rentable square foot payable by Tenant
            for the initial Premises, subject to adjustment at the same time as
            and pursuant to the same schedule for the initial Premises as set
            forth in Section I.D of the Lease and Section I of this Exhibit E,
            or (ii) the Prevailing Market for First Offer Space (defined in
            Section II.H below). If Landlord determines in the First Offer
            Notice that the First Offer Rent shall be the Prevailing Market for
            First Offer Space, then concurrent with Tenant's delivery of
            Tenant's Election Notice exercising such right of first offer,
            Tenant may object in writing to Landlord's determination of the
            Prevailing Market for First Offer Space set forth in the First Offer
            Notice, in which case the Prevailing Market for First Offer Space
            shall be determined in accordance with the procedures set forth in
            Section II.I below. If Tenant does not timely object in writing to
            Landlord's determination of the Prevailing Market for First Offer
            Space, then Tenant shall be deemed to have accepted such
            determination and the procedures in Section II.I below shall not
            apply.

      E.    Construction In First Offer Space. If Tenant leases the First Offer
            Space pursuant to the terms of this Section II, Tenant shall take
            the First Offer Space in its "as is" condition as of the date of
            delivery of such space by Landlord to Tenant, and Tenant may
            construct, at Tenant's sole cost and expense, improvements in the
            First Offer Space pursuant to the terms of Section IX.C of the
            Lease; provided, however, Tenant may receive a tenant improvement
            allowance to construct tenant improvements in the First Offer Space
            to the extent, if any, included in the definition of "First Offer
            Rent", as set forth in Section II.D above.

      F.    Amendment to Lease. If Tenant timely exercises its right of first
            offer, Landlord shall prepare an amendment (the "Right of First
            Offer Amendment") adding the applicable First Offer Space to the
            Premises on the terms set forth in this Section II. A copy of the
            Right of First Offer Amendment shall be sent to Tenant within a
            reasonable time after Landlord's receipt of Tenant's Election
            Notice, and Tenant shall execute and return the Right of First Offer
            Amendment to Landlord within a reasonable time period thereafter,
            but an otherwise valid exercise of the right of first offer shall be
            fully effective whether or not the Right of First Offer Amendment is
            executed. Tenant shall commence payment of Rent for the First Office
            Space, and the term of Tenant's lease of the First Offer Space shall
            commence upon the date of delivery of the First Offer Space to
            Tenant (the "First Offer Commencement Date") and terminate
            coterminously with the termination of the Term, as the same may be
            extended pursuant to Section I of this Exhibit E, above.

                                    EXHIBIT E

      G.    Suspension of Right of First Offer. At Landlord's option, in
            addition to its other remedies under the Lease, Tenant shall not
            have the right to lease the First Offer Space, as provided in this
            Section II, if, as of the date of the attempted exercise of such
            right of first offer by Tenant, or as of the scheduled date of
            delivery of the First Offer Space to Tenant, (i) there is less than
            three (3) years left in the Term, or (ii) Tenant is in default under
            the Lease beyond any applicable notice and cure periods. In
            addition, and notwithstanding anything to the contrary contained in
            this Section II, the rights to lease the First Offer Space contained
            in this Section II shall be personal to the Tenant originally named
            in the Lease (the "Original Tenant") and the assignee under a
            Permitted Transfer by the Original Tenant (the "Permitted
            Assignee"), and may only be exercised by the Original Tenant or such
            Permitted Assignee, as the case may be (but not by any other
            assignee, sublessee or transferee of Tenant's interest in the Lease
            or the Premises, or any part thereof) if, at the time of the
            attempted exercise of such right of first offer, the Original Tenant
            and/or the Permitted Assignee is in physical occupancy and
            possession of at least 75% of the then existing Premises.

      H.    Definition of Prevailing Market for First Office Space. For purposes
            of this Section II, "Prevailing Market for First Offer Space" shall
            mean the annual rental rate per rentable square foot for space
            comparable to the First Offer Space in the Building and the
            Comparable Buildings under leases and renewal and expansion
            amendments being entered into at or about the time that the
            Prevailing Market for First Office Space is being determined, giving
            appropriate consideration to tenant concessions, brokerage
            commissions, tenant improvement allowances, existing improvements in
            the space in question, and the method of allocating operating
            expenses and taxes. Notwithstanding the foregoing, space leased
            under any of the following circumstances shall not be considered to
            be comparable for purposes hereof: (i) the lease term is for less
            than the lease term of the applicable First Offer Space, (ii) the
            space is encumbered by the option rights of another tenant, or (iii)
            the space has a lack of windows and/or an awkward or unusual shape
            or configuration. The foregoing is not intended to be an exclusive
            list of space that will not be considered to be comparable.

      I.    Procedure for Determining Prevailing Market for First Offer Space.
            If Tenant timely objects to Landlord's determination of the
            Prevailing Market for First Offer Space in Tenant's Election Notice,
            then Landlord and Tenant shall work together in good faith to agree
            upon the Prevailing Market for First Offer Space. Upon agreement
            Tenant shall provide Landlord with a written notice and Landlord and
            Tenant shall enter into the Right of First Offer Amendment in
            accordance with the terms and conditions hereof. Notwithstanding the
            foregoing, if Landlord and Tenant are unable to agree upon the
            Prevailing Market for First Offer Space within 30 days after the
            date on which Tenant provides Landlord with Tenant's Election
            Notice, either party, by written notice to the other (the "First
            Offer Arbitration Notice") within 5 Business Days after the
            expiration of such 30 day period, shall have the right to have the
            Prevailing Market for First Offer Space determined in accordance
            with the following procedures. If neither party

                                    EXHIBIT E
                                       -8-
<PAGE>

            exercises its right to arbitrate, Tenant's exercise of such right of
            first offer shall be deemed to be null and void and of no further
            force and effect. If either party timely provides the other with a
            First Offer Arbitration Notice, Landlord and Tenant, within 10 days
            after the date of the First Offer Arbitration Notice, shall each
            simultaneously submit to the other, in a sealed envelope, its good
            faith estimate of the Prevailing Market for First Offer Space
            (collectively referred to as the "First Offer Estimates"). If the
            higher of such First Offer Estimates is not more than 105% of the
            lower of such First Offer Estimates, the Prevailing Market for First
            Offer Space shall be the average of the two First Offer Estimates.
            If the Prevailing Market for First Offer Space is not resolved by
            the exchange of First Offer Estimates, Landlord and Tenant, within
            10 days after the exchange of First Offer Estimates, shall each
            select an appraiser to determine which of the two applicable First
            Offer Estimates most closely reflects the Prevailing Market for
            First Offer Space. Each appraiser so selected shall be certified as
            an MAI appraiser or as an ASA appraiser and shall have had at least
            5 years experience within the previous 10 years as a real estate
            appraiser working in the vicinity with working knowledge of current
            rental rates and practices. Upon selection, Landlord's and Tenant's
            appraisers shall work together in good faith to agree upon which of
            the two First Offer Estimates most closely reflects the Prevailing
            Market for First Offer Space. The applicable First Offer Estimate
            chosen by such appraisers shall be binding on both Landlord and
            Tenant as the Prevailing Market for First Offer Space. If either
            Landlord or Tenant fails to appoint an appraiser within the 10 day
            period referred to above, the appraiser appointed by the other party
            shall be the sole appraiser for the purposes hereof. If the two
            appraisers cannot agree upon which of the two applicable First Offer
            Estimates most closely reflects the Prevailing Market for First
            Offer Space, within the 20 days after their appointment, then,
            within 10 days after the expiration of such 20 day period, the 2
            appraisers shall select a third appraiser meeting the aforementioned
            criteria. Once the third appraiser has been selected as provided for
            above, then, as soon thereafter as practicable but in any case
            within 14 days, the third appraiser shall make his determination of
            which of the two applicable First Offer Estimates most closely
            reflects the Prevailing Market for First Offer Space and such First
            Offer Estimate shall be binding on both Landlord and Tenant as the
            Prevailing Market for First Offer Space. If the arbitrator believes
            that expert advice would materially assist him, he may retain one or
            more qualified persons, provided they have had no dealings with
            Landlord or Tenant within the immediately preceding 12 month period,
            to provide such expert advice. The parties shall share equally in
            the costs of the arbitrator and of any experts reasonably retained
            by the arbitrator. Any fees of any appraiser, counsel or experts
            engaged directly by Landlord or Tenant, however, shall be borne by
            the party retaining such appraiser, counsel or expert. In the event
            that the Prevailing Market for First Offer Space has not been
            determined by the commencement date of Tenant's lease of the
            applicable First Offer Space, Tenant shall pay Rent upon the terms
            and conditions in effect for the initial Premises until such time as
            the Prevailing Market for First Offer Space has been determined.
            Upon such determination, the Base Rent for the First Offer Space
            shall be retroactively adjusted, if necessary, to the commencement
            of

                                    EXHIBIT E

<PAGE>

            Tenant's lease of the applicable First Offer Space, using the
            formula set forth in the first sentence of Section II.D above. If
            such adjustment results in an underpayment of Base Rent by Tenant,
            Tenant shall pay Landlord the amount of such underpayment within 30
            days after the determination thereof. If such adjustment results in
            an overpayment of Base Rent by Tenant, Landlord shall credit such
            overpayment against the next installment of Base Rent due under the
            Lease and, to the extent necessary, any subsequent installments
            until the entire amount of such overpayment has been credited
            against Base Rent, or at Tenant's election, reimburse Tenant within
            30 days.

                                PARKING AGREEMENT

      This Exhibit (the "Parking Agreement") is attached to and made a part of
the Lease by and between [[LANDLORD'S NAME AND ENTITY TYPE TO BE PROVIDED]]
("Landlord") and INKTOMI CORPORATION, A DELAWARE CORPORATION ("Tenant") for
space in the Building located at Bayside Towers.

1.    The capitalized terms used in this Parking Agreement shall have the same
      definitions as set forth in the Lease to the extent that such capitalized
      terms are defined therein and not redefined in this Parking Agreement. In
      the event of any conflict between the Lease and this Parking Agreement,
      the latter shall control.

2.    Landlord hereby grants to Tenant and persons designated by Tenant a right
      to use up to four (4) non-reserved parking spaces per each 1,000 rentable
      square feet of the Premises (the "Parking Rights") in the surface parking
      areas in existence as of September 1, 2002 which service the Building
      ("Parking Facility") during the Term. The use of such spaces shall be
      provided free of charge during the initial term, provided that during the
      Option Terms Tenant shall pay the parking rate, if any, determined during
      the Prevailing Market determination of the Base Rent for the Premises for
      the Option Term, as set forth in Section I of Exhibit E.

3.    In exercising the Parking Rights, Tenant shall at all times comply with
      all applicable ordinances, rules, regulations, codes, laws, statutes and
      requirements of all federal, state, county and municipal governmental
      bodies or their subdivisions respecting the use of the Parking Facility.
      Landlord reserves the right to adopt, modify and enforce reasonable rules
      ("Rules") governing the use of the Parking Facility from time to time
      including any key-card, sticker or other identification or entrance system
      and hours of operation. The Rules set forth herein are currently in
      effect. Landlord may refuse to permit any person who violates such Rules
      to park in the Parking Facility, and any violation of the Rules shall
      subject the car to removal from the Parking Facility.

4.    The Parking Rights shall be provided on a non-designated "first-come,
      first-served" basis. Tenant acknowledges that Landlord has no liability
      for claims arising through acts or omissions of any independent operator
      of the Parking Facility. Landlord shall have no liability whatsoever for
      any damage to items located in the Parking Facility, nor for any personal
      injuries or death arising out of any matter relating to the Parking
      Facility, and in all events, Tenant agrees to look first to its insurance
      carrier and to require that Tenant's employees look first to their
      respective insurance carriers for payment of any losses sustained in
      connection with any use of the Parking Facility. Tenant hereby waives on
      behalf of its insurance carriers all rights of subrogation against
      Landlord or Landlord's agents. Landlord reserves the right to assign
      specific parking spaces, and to reserve parking spaces for visitors, small
      cars, handicapped persons and for other tenants, guests of tenants or
      other parties, which assignment and reservation or spaces may be relocated
      as determined by Landlord from time to time, and Tenant and persons
      designated by Tenant

                                    EXHIBIT F
                                       -1-
<PAGE>

      hereunder shall not park in any location designated for such assigned or
      reserved parking spaces. Tenant acknowledges that the Parking Facility may
      be closed entirely or in part in order to make repairs or perform
      maintenance services, or to alter, modify, re-stripe or renovate the
      Parking Facility, or if required by casualty, strike, condemnation, act of
      God, governmental law or requirement or other reason beyond the operator's
      reasonable control. In such event, Landlord shall refund any prepaid
      parking fee hereunder, prorated on a per diem basis.

5.    If Tenant shall default under this Parking Agreement, the operator shall
      have the right to remove from the Parking Facility any vehicles hereunder
      which shall have been involved or shall have been owned or driven by
      parties involved in causing such default, without liability therefor
      whatsoever. In addition, if Tenant shall default under this Parking
      Agreement, Landlord shall have the right to cancel this Parking Agreement
      on 10 days' written notice, unless within such 10 day period, Tenant cures
      such default. If Tenant defaults with respect to the same term or
      condition under this Parking Agreement more than 3 times during any 12
      month period, and Landlord notifies Tenant thereof promptly after each
      such default, the next default of such term or condition during the
      succeeding 12 month period, shall, at Landlord's election, constitute an
      incurable default. Such cancellation right shall be cumulative and in
      addition to any other rights or remedies available to Landlord at law or
      equity, or provided under the Lease (all of which rights and remedies
      under the Lease are hereby incorporated herein, as though fully set
      forth). Any default by Tenant under the Lease shall be a default under
      this Parking Agreement, and any default under this Parking Agreement shall
      be a default under the Lease.

                                      RULES

      (i)   The Parking Facility hours shall be [TO BE REASONABLY PROVIDED BY
            LANDLORD] A.M. to [TO BE REASONABLY PROVIDED BY LANDLORD] P.M. on
            Business Days and [TO BE REASONABLY PROVIDED BY LANDLORD] A.M. to
            [TO BE REASONABLY PROVIDED BY LANDLORD] P.M. on Saturday, however,
            subject to the provisions set forth herein, Tenant shall have access
            to the Parking Facility on a 24 hour basis, 7 days a week.
            Notwithstanding the foregoing, Landlord reserves the right to
            establish and change Parking Facility hours from time to time.
            Tenant shall not store or permit its employees to store any
            automobiles in the Parking Facility without the prior written
            consent of the operator. Except for emergency repairs, Tenant and
            its employees shall not perform any work on any automobiles while
            located in the Parking Facility, or on the Property. If it is
            necessary for Tenant or its employees to leave an automobile in the
            Parking Facility overnight, Tenant shall provide the operator with
            prior notice thereof designating the license plate number and model
            of such automobile.

      (ii)  Cars must be parked entirely within the stall lines painted on the
            floor, and only small cars may be parked in areas reserved for small

      (v)   Parking spaces reserved for handicapped persons must be used only by
            vehicles properly designated.

      (vi)  Parking is prohibited in all areas not expressly designated for
            parking, including without limitation:

            (a)   Areas not striped for parking

            (b)   aisles

            (c)   where "no parking" signs are posted

            (d)   ramps

            (e)   loading zones

      (vii)  Parking stickers, key cards or any other devices or forms of
             identification or entry supplied by the operator shall remain the
             property of the operator. Such device must be displayed as
             requested and may not be mutilated in any manner. The serial number
             of the parking identification device may not be obliterated.
             Parking passes and devices are not transferable and any pass or
             device in the possession of an unauthorized holder will be void.

      (viii) Monthly fees shall be payable in advance prior to the first day of
             each month. Failure to do so will automatically cancel parking
             privileges and a charge at the prevailing daily parking rate will
             be due. No deductions or allowances from the monthly rate will be
             made for days on which the Parking Facility is not used by Tenant
             or its designees.

      (ix)   Parking Facility managers or attendants are not authorized to make
             or allow any exceptions to these Rules.

      (x)    Every parker is required to park and lock his/her own car.

      (xi)   Loss or theft of parking pass, identification, key cards or other
             such devices must be reported to Landlord and to the Parking
             Facility manager immediately. Any parking devices reported lost or
             stolen found on any authorized car will be confiscated and the
             illegal holder will be subject to prosecution. Lost or stolen
             passes and devices found by Tenant or its employees must be
             reported to the office of the Parking Facility immediately.

      (xii)  Washing, waxing, cleaning or servicing of any vehicle by the
             customer and/or his agents is prohibited. Parking spaces may be
             used only for parking automobiles.

      (xiii) Tenant agrees to acquaint all persons to whom Tenant assigns a
             parking space with these Rules.

6.    TENANT ACKNOWLEDGES AND AGREES THAT, TO THE FULLEST EXTENT PERMITTED BY
      LAW, LANDLORD SHALL NOT BE RESPONSIBLE FOR ANY LOSS OR DAMAGE TO TENANT OR
      TENANT'S PROPERTY (INCLUDING, WITHOUT LIMITATIONS, ANY LOSS OR DAMAGE TO
      TENANT'S AUTOMOBILE OR THE CONTENTS THEREOF DUE TO THEFT, VANDALISM OR
      ACCIDENT) ARISING FROM OR RELATED TO TENANT'S USE OF THE PARKING FACILITY
