                                   APPENDIX A

                          AUTOMATIC STOCK OPTION GRANTS
                             FOR ELIGIBLE DIRECTORS

(AMENDED AND RESTATED BY THE BOARD OF DIRECTORS EFFECTIVE AS OF JANUARY 1, 2004)

      This Appendix A is adopted under and as a part of the Ask Jeeves, Inc.
1999 Equity Incentive Plan. This Appendix A provides for the automatic grant of
certain Options, on the terms and conditions set forth below, under the Plan to
certain eligible Directors. Capitalized terms used in this Appendix A are used
as defined in the Plan if not otherwise defined herein.

A.1 INTRODUCTION.

      (A) PURPOSE. The Company, by granting stock options as provided under this
Appendix A, seeks to attract and retain the services of highly qualified
non-employee members of the Board by providing to them a significant equity
interest in the Company, to more closely link the interests of those directors
with the Company's stockholders, and to help provide those directors with
reasonable and fair compensation.

      (B) EFFECTIVE DATE. This restated version of Appendix A is effective as of
January 1, 2004 (the "Appendix A Approval Date").

      (C) ELIGIBLE DIRECTORS. The persons eligible to receive Options under this
Appendix A (each an "Eligible Director") are (1) the Chairman of the Board of
Directors (whether or not an employee of the Company or one of its Affiliates),
and (2) non-emeritus Directors who are not employed by either the Company or one
of its Affiliates. This version of Appendix A applies only to Options granted to
Eligible Directors pursuant to this Appendix A after the Appendix A Approval
Date. This Appendix A does not apply to any other Option or Stock Award granted
under the Plan. Options granted pursuant to this Appendix A before the Appendix
A Approval Date shall be governed by the particular version of this Appendix A
as in effect as of the applicable date of grant of the Option. This Appendix A
does not limit the authority of the Board or a Committee to grant discretionary
Options or other Stock Awards under other provisions of the Plan.

      (D) PLAN PROVISIONS. Any Option granted under this Appendix A shall be
governed by the provisions of this Appendix A and by the provisions of the Plan.
Each Option granted under this Appendix A shall be subject to, without
limitation, the provisions of Section 11 of the Plan.

      (E) BOARD AUTHORITY. Options granted pursuant to this Appendix A shall be
automatic and, to the maximum extent possible, self-effectuating. The Board's
authority pursuant to Section 3 of the Plan shall, however, extend to this
Appendix A and Options granted hereunder.

                                      A-1
<PAGE>
      (F) AMENDMENT. The Board may amend this Appendix A from time to time
pursuant to Section 12 of the Plan. The Board may suspend or reduce new Option
grants under this Appendix A (to any or all Eligible Directors) or terminate
this Appendix A as to new Option grants at any time; provided that any such
action shall not affect any Option theretofore outstanding under this Appendix
A.

      (G) SHARE LIMIT. Options granted under this Appendix A shall be subject to
the limit set forth in Section 4(a) applicable to all Stock Awards granted under
the Plan. If one or more Options are to be granted on a specific date and such
Option(s) would otherwise exceed the number of shares that can then be subject
to Options granted under the Plan pursuant to Section 4(a) of the Plan, such
Option(s) shall be granted and shall cover the maximum number of shares (on a
pro-rata basis in the event more than one Option is to be granted) that are
available for such purposes within the limits of Section 4(a) of the Plan.

A.2 AUTOMATIC OPTION GRANTS.

      (A) NEW DIRECTOR GRANTS. Each individual who first becomes an Eligible
Director on or after the Appendix A Approval Date (other than an individual who
was employed by the Company or an Affiliate at any time within the six-month
period preceding the date on which he or she first becomes an Eligible Director)
shall automatically be granted an Option as of the date he or she first becomes
an Eligible Director to purchase 50,000 shares of Common Stock (subject to
adjustment pursuant to Section 11 of the Plan).

      (B) QUARTERLY AWARDS. On the first business day of each calendar quarter
during the term of the Plan, commencing with the calendar quarter that commences
on the Appendix A Approval Date, each person who is an Eligible Director on that
date and who has served as a member of the Board continuously for at least six
months as of that date shall automatically be granted an Option as of that date
to purchase 3,000 (or, in the case of the Chairman of the Board if he or she is
then an Eligible Director, 4,500) shares of Common Stock (subject to adjustment
pursuant to Section 11 of the Plan).

      (C) EXERCISE PRICE. Each Option granted under this Appendix A shall have a
per share exercise price equal to the Fair Market Value of a share of Common
Stock as of the day such Option is granted.

      (D) VESTING. Each Option granted under this Appendix A shall be
exercisable only to the extent that it is vested. Each Option granted pursuant
to Section A.2(a) shall vest as to 25% of the total number of shares of Common
Stock subject thereto on the first anniversary of the grant date of the Option
and as to an additional 1/48th of the total number of shares of Common Stock
subject thereto on the first day of each month for the thirty-six months
following the month in which the first anniversary of the grant date of the
Option occurs; provided, in each case, that the Eligible Director who received
the Option has remained in Continuous Service through the respective vesting
date. Each Option granted pursuant to Section A.2(b) shall vest as to 25% of the
total number of shares of Common Stock subject thereto on the date that is three
months after the grant date of the Option, shall vest as to an additional 25% of
the total number of shares of Common Stock subject thereto on the date that is
six months after the grant date of the Option, shall vest as to an additional
25% of the total number of shares of Common Stock subject thereto on the date
that is nine months after the grant date of the Option, and shall vest as to the
final 25% of the total number of shares of Common Stock subject thereto on the
first

                                      A-2
<PAGE>
anniversary of the grant date of the Option; provided, in each case, that the
Eligible Director who received the Option has remained in Continuous Service
through the respective vesting date. The vesting schedule applicable to an
Option requires continued service through each applicable vesting date as a
condition to the vesting of the applicable installment of the Option and the
rights and benefits under this Plan. Service for only a portion of a vesting
period, even if substantial, will not entitle the Optionholder to any
proportionate vesting or avoid or mitigate a termination of rights and benefits
upon or following a termination of services.

      (E) EXPIRATION. Subject to earlier termination pursuant to Section A.4
herein or Section 11 of the Plan, Options granted under this Appendix A shall
expire at the close of business on the day before the tenth anniversary of the
date of grant of the Option.

      (F) CONSIDERATION. The purchase price of Common Stock acquired pursuant to
an Option granted under this Appendix A shall be paid in full at the time of
purchase, to the extent permitted by applicable statutes and regulations, either
(1) in cash, by electronic funds transfer or check payable to the Company, (2)
by notice and third party payment in such manner as may be authorized by the
Board or pursuant to such "cashless exercise" procedures with third parties who
provide financing of (or who otherwise facilitate) the exercise of Options in
such manner as may be authorized by the Board, or (3) by delivery to the Company
of other Common Stock; provided, however, that any Common Stock delivered to pay
such purchase price that was originally acquired by the Optionholder from the
Company, upon exercise of a stock option or otherwise, must have been owned by
the Optionholder for more than six months before being so used to pay such
purchase price. Shares of Common Stock used to satisfy the exercise price of an
Option shall be valued at their Fair Market Value on the date of exercise of the
Option.

      (G) AGREEMENT. Options granted under this Appendix A will be evidenced by
an Option Agreement, signed by a duly authorized officer of the Company and by
the Option recipient. Each Option Agreement shall be in the form attached as
Exhibit A to this Appendix A, or such other form as may be approved by the Board
for use under this Appendix A from time to time, and shall be subject to such
other terms and conditions as may be set forth therein. Each Option granted
under this Plan shall be a Nonstatutory Stock Option and shall not be an
Incentive Stock Option.

A.3 NON-TRANSFERABILITY OF OPTIONS.

      An Option granted under this Appendix A shall not be subject in any manner
to sale, transfer, anticipation, alienation, assignment, pledge, encumbrance or
charge and shall be exercisable during the lifetime of the Optionholder only by
the Optionholder. Amounts payable or shares issuable pursuant to any Option
shall be delivered only to (or for the account of) the Optionholder.

      The Board may permit Options granted under this Appendix A to be exercised
by and paid to certain persons or entities related to the Optionholder pursuant
to such conditions and procedures, including limitations on subsequent
transfers, as the Board may establish. Any permitted transfer shall be subject
to the condition that the Board receive evidence satisfactory to it that the
transfer (1) is being made for essentially estate and/or tax planning purposes
on a gratuitous or donative basis and without consideration (other than nominal
consideration or in exchange for an interest in a qualified transferee), and (2)
will not compromise the Company's

                                      A-3
<PAGE>
ability to register shares issuable under the Plan on SEC Form S-8 under the
Securities Act, or to rely on such registration in connection with an Option
exercise.

      The exercise and transfer restrictions in the first paragraph of this
Section A.3 will not, however, apply to:

            (1)   transfers to the Company,

            (2)   the designation of a beneficiary to receive benefits in the
                  event of the Optionholder's death or, if the Optionholder has
                  died, transfers to or exercises by the Optionholder's
                  beneficiary, or, in the absence of a validly designated
                  beneficiary, transfers by will or the laws of descent and
                  distribution,

            (3)   transfers to a family member (or former family member)
                  pursuant to a domestic relations order if received by the
                  Board prior to the exercise of the Option,

            (4)   if the Optionholder has suffered a disability, permitted
                  transfers or exercises on behalf of the Optionholder by his or
                  her legal representative, or

            (5)   the authorization by the Board of "cashless exercise"
                  procedures with third parties who provide financing for the
                  purpose of (or who otherwise facilitate) the exercise of
                  Options consistent with applicable laws and the express
                  authorization of the Board.

A.4 TERMINATION OF CONTINUOUS SERVICE.

      (A) TERMINATION OF CONTINUOUS SERVICE. If an Optionholder's Continuous
Service terminates (for any reason other than upon the Optionholder's death or
Disability), then, subject to earlier termination pursuant to Section 11 of the
Plan or Section A.2(e):

            -     the unvested portion of the Optionholder's Option shall
                  automatically terminate as of such cessation of service;

            -     the Optionholder (or his or her permitted transferee, if
                  applicable) may exercise his or her Option to the extent
                  vested as of such cessation of service but only within the
                  90-day period following such cessation of service; and

            -     the portion of the Option that is vested on the Optionholder's
                  cessation of service and is not exercised within such 90-day
                  period shall automatically terminate on the 90th day following
                  the date the Optionholder's Continuous Service terminated.

      (B) DISABILITY OF OPTIONHOLDER. If an Optionholder's Continuous Service
terminates as a result of the Optionholder's Disability, then, subject to
earlier termination pursuant to Section 11 of the Plan or Section A.2(e):

            -     the unvested portion of the Optionholder's Option shall
                  automatically terminate as of such cessation of service;

                                       A-4
<PAGE>
            -     the Optionholder (or his or her permitted transferee, if
                  applicable) may exercise his or her Option to the extent
                  vested as of such cessation of service but only within the
                  one-year period following such cessation of service; and

            -     the portion of the Option that is vested on the Optionholder's
                  cessation of service and is not exercised within such one-year
                  period shall automatically terminate on the first anniversary
                  of the date the Optionholder's Continuous Service terminated.

      (C) DEATH OF OPTIONHOLDER. If an Optionholder's Continuous Service
terminates as a result of the Optionholder's death, then, subject to earlier
termination pursuant to Section 11 of the Plan or Section A.2(e):

            -     the unvested portion of the Optionholder's Option shall
                  automatically terminate as of such cessation of service;

            -     the Optionholder's estate, or person who acquired the right to
                  exercise the Option by bequest or inheritance, or other person
                  designated to exercise the option upon the Optionholder's
                  death pursuant to Section A.3, as applicable, may exercise the
                  Optionholder's Option to the extent vested as of such
                  cessation of service but only within the one-year period
                  following such cessation of service; and

            -     the portion of the Option that is vested on the Optionholder's
                  cessation of service and is not exercised within such one-year
                  period shall automatically terminate on the first anniversary
                  of the date the Optionholder's death.

      This Agreement between Ask Jeeves, Inc., a Delaware corporation (the
"Company"), and _________________ (the "Grantee") sets forth the specific terms
and conditions of a stock option granted to the Grantee under Appendix A of the
Ask Jeeves, Inc. 1999 Equity Incentive Plan (the "Plan"). (All references to the
Plan in this Agreement include the provisions of Appendix A to the Plan.)

1. AWARD OF STOCK OPTIONS. The Company hereby awards a nonqualified stock option
(the "Option") to the Grantee to purchase, subject to the terms and conditions
set forth below, the number of shares of the Company's common stock ("Common
Stock") set forth below at the price per share set forth below:

         Date of Grant ("Award Date")                _____

[ALTERNATIVE FOR OPTIONS GRANTED PURSUANT TO SECTION A.2(A) (NEW DIRECTOR
GRANTS) OF THE PLAN: The Option shall vest as to 25% of the total number of
shares subject to the Option on the first anniversary of the Award Date and as
to an additional 1/48th of the total number of shares subject to the Option on
the first day of each month for the thirty-six months following the month in
which the first anniversary of the Award Date occurs; subject, in each case, to
the termination of service rules of Section A.4 of the Plan.] As provided in
Section A.2(e) of the Plan, there will be no pro-rated vesting if the Grantee's
service terminates for any reason between scheduled vesting dates.

      3. EXERCISE; TERMINATION. The Option is exercisable only to the extent
that it is vested and only on or before its expiration or earlier termination.
The expiration date of the Option is set forth above and, notwithstanding that
date, the Option is subject to earlier termination pursuant to Section A.2(f),
A.4 and Section 11 of the Plan. The Option shall be exercisable by the delivery
to the Secretary of the Company of a written notice (in such form as the Company
may require from time to time) stating the number of shares of Common Stock to
be purchased

--------

1 Subject to adjustment pursuant to Section 11(a) of the Plan.

2 Subject to earlier termination as provided herein.

                                      A-i
<PAGE>
pursuant to the Option and accompanied by payment in full for the exercise price
of the shares to be purchased in a manner authorized pursuant to Section A.2(g)
of the Plan. Any such notice shall be effective only when received by the
Secretary of the Company. The Option may not be exercised as to any fractional
share and no fewer than 1001 shares may be purchased at any one time, unless the
number purchased is the total number at the time exercisable under the Option.

4. NO TRANSFER OR SERVICE RIGHTS. Nothing contained in this Agreement
constitutes an employment or service commitment by the Company or any affiliate,
confers upon the Grantee any right to remain in employ of or service to the
Company or any affiliate, interferes in any way with the right of the Company or
any affiliate at any time to terminate such employment service, or affects the
right of the Company or any affiliate to increase or decrease the recipient's
other compensation. The Option and any other rights of the Grantee under this
Agreement or the Plan are nontransferable and exercisable only by the Grantee,
except as set forth in Section A.3 of the Plan.

5. THE PLAN GOVERNS. The Option and all rights of the Grantee under this
Agreement are subject to all of the terms and conditions of the Plan,
incorporated herein by this reference. In the event of a conflict or
inconsistency between the terms and conditions of this Agreement and of the
Plan, the terms and conditions of the Plan shall govern. Provisions of the Plan
that confer discretionary authority on the Board do not and shall not be deemed
to create any rights in the Grantee unless such rights are expressly set forth
herein or are otherwise conferred on the Grantee in the sole discretion, and by
appropriate action, of the Board after the date hereof. By executing this
Agreement, the Grantee represents that he/she is familiar with the terms and
conditions of this Agreement and the Plan, hereby acknowledges receipt of both
documents and the current Prospectus for the Plan, and hereby accepts the Option
subject to all of the terms and conditions hereof.

6. ENTIRE AGREEMENT. This Agreement and the Plan together constitute the entire
agreement and supersede all prior understandings and agreements, written or
oral, of the parties hereto with respect to the subject matter hereof. The Plan
and this Agreement may be amended pursuant to Section 12 of the Plan. Such
amendment must be in writing and signed by the Company. The Company may,
however, unilaterally waive any provision hereof in writing to the extent such
waiver does not adversely affect the interests of the Grantee hereunder, but no
such waiver shall operate as or be construed to be a subsequent waiver of the
same provision or a waiver of any other provision hereof.

7. GOVERNING LAW. This Agreement shall be construed in accordance with and
governed by the laws of the State of California without regard to conflict of
law principles thereunder.

                                      A-ii

provided that no additional rent or use fee shall be charged to Tenant for the
use of such risers). All of the windows and outside walls of the Premises and
any space in the Premises used for shafts, stacks, pipes, conduits, ducts,
electrical equipment or other utilities or Building facilities are reserved
solely to Landlord (subject to any express provisions of this Lease granting

                     (representing Tenant).

            3.  Term; Delivery of Possession of Premises.

                a. The term of this Lease shall commence on the Commencement
Date (as defined in Paragraph 2.b.) and, unless sooner terminated pursuant to
the terms hereof or at law, shall expire on the Expiration Date (as defined in
Paragraph 2.b.). Upon either party's request after the Commencement Date,
Landlord and Tenant shall execute a letter in substantially the form of Exhibit
C attached hereto confirming the Commencement Date.

                b. Landlord shall deliver the Premises to Tenant in their as-is
condition, upon the execution and delivery of this Lease by and between the
parties. In the event of any delay in the delivery of the Premises to Tenant in
their as-is condition caused or occasioned by fire or other casualty, acts of
God or any other cause beyond the reasonable control of Landlord ("Force
Majeure"), this Lease shall not be void or voidable, nor shall Landlord be
liable to Tenant for any loss or damage resulting therefrom, but Landlord shall
use reasonable efforts to deliver the Premises to Tenant as soon as reasonably
possible after the execution and delivery of the Lease by and between the
parties.

            Promptly following the Commencement Date, Landlord shall cause
Landlord's designated contractor to commence the Ground Floor Demising Work (as
defined in Paragraph 4.a. below). If the Ground Floor Demising Work is not
completed on or before the date (the "Outside Completion Date") that is one
hundred twenty (120) days following the Commencement Date (provided, however,
that the Outside Completion Date shall be extended by the length of any delay in
the completion of the Ground Floor Demising Work caused or occasioned by Force
Majeure and/or by a Tenant Delay, as defined in Paragraph 4.c. below), this
Lease shall not be void or voidable (except as otherwise provided in the
immediately following grammatical paragraph), nor shall Landlord be liable to
Tenant for any loss or damage resulting therefrom, but (i) Landlord shall use
commercially reasonable efforts to complete the Ground Floor Demising Work as
soon as reasonably possible after the Outside Completion Date (as the same may
have been extended pursuant to the foregoing) and (ii) at such time as Tenant is
otherwise obligated to commence payment of Monthly Rent for the Premises, the
Monthly Rent for the entire Premises shall be abated one (1) day for each day
beyond the Outside Completion Date (as the same may have been extended pursuant
to the above) that the Ground Floor Demising Work was not completed.

            Notwithstanding the foregoing, if the Ground Floor Demising Work is
not completed on or before the date (the "Termination Trigger Date") that is one
hundred fifty (150) days following the Commencement Date (provided, however,
that the Termination Trigger Date shall be extended by the length of any delay
in the completion of the Ground Floor Demising Work caused or occasioned by
Force Majeure and/or by a Tenant Delay) then Tenant may deliver written notice
to Landlord (the "Termination Notice"), within three (3) business days after the
Termination Trigger Date, electing to terminate this Lease effective on the date
(the "Termination Date") which is thirty (30) days after the delivery to
Landlord of the Termination Notice. Notwithstanding the foregoing, if Tenant
delivers a Termination Notice, but Landlord completes the Ground Floor Demising
Work within the thirty (30) day period following the delivery to Landlord of the
Termination Notice, then the Termination Notice shall be of no force or effect.
However, if Landlord does not complete the Ground Floor Demising Work within the
thirty (30) day period, then this Lease shall terminate at the end of the thirty
(30) day period.

                                       2

<PAGE>

                Tenant's foregoing rent credit and termination rights are
Tenant's sole remedy in the event of delays in the completion of the Ground
Floor Demising Work.

                c. Tenant may, concurrently with the performance by Landlord's
contractor of the Ground Floor Demising Work, commence construction within the
Ground Floor Premises of the portion of the Initial Alterations (as defined in
Paragraph 4.a. below) consisting of the construction of a computer data center
within the Ground Floor Premises (the "Data Center Construction"), provided that
such construction by Tenant does not interfere with the performance by
Landlord's contractor of the Ground Floor Demising Work. Any interference in the
performance and/or completion by Landlord's contractor of the Ground Floor
Demising Work caused by Tenant's performance of the Data Center Construction, or
any other delay in the completion of the Ground Floor Demising Work caused by
Tenant or its employees or agents, shall constitute a "Tenant Delay."

            4.  Premises As-is: Ground Floor Demising Work; Initial Alterations;
Alterations Allowance.

                a. Premises As-Is; Ground Floor Demising Work. Promptly
following the delivery of the Premises to Tenant in their as-is condition,
Landlord shall cause Landlord's designated contractor to construct the demising
walls (using building standard materials) required to separate the Ground Floor
Premises from the adjacent areas of the ground floor of the Building, such work
being referred to in this Lease as the "Ground Floor Demising Work." Except for
the Ground Floor Demising Work, the provisions in Paragraph 4.b. below regarding
the Alterations Allowance (as defined therein) and as otherwise set forth
herein, Tenant shall accept the Premises in their as-is condition and Landlord
shall have no obligation to make or pay for any improvements or renovations in
or to the Premises or to otherwise prepare the Premises for Tenant's occupancy.
Notwithstanding the foregoing, upon Landlord's delivery of the Premises to
Tenant, (i) the Premises shall be in good, vacant and broom clean condition and
(ii) all base Building systems serving the Premises (excluding the Ground Floor
Premises) shall be in good working order and condition, with such systems
distributed throughout the Premises based on the configuration of the Premises
at the time of delivery of the Premises to Tenant, it being acknowledged that
changes to the distribution of the base Building systems required as a result of
the Initial Alterations shall be performed by Tenant as a part of the Initial
Alterations.

                The parties acknowledge that Tenant intends to make certain
alterations and improvements (the "Initial Alterations") to the Premises on or
after the Commencement Date of this Lease. The construction of the Initial
Alterations shall be governed by Paragraph 9 below; provided, however, that, for
the Initial Alterations only, the Alteration Operations Fee provided for in
Paragraph 9.a. below shall not exceed three percent (3%) of the Alterations
Allowance actually disbursed by Landlord for the design and construction of the
Initial Alterations. The contractor selected by Tenant to construct the Initial
Alterations is referred to hereinafter as "Tenant's Contractor."

                Tenant acknowledges and agrees that the Initial Alterations must
include the installation by Tenant's Contractor of the equipment and
installations required to bring electricity to the Ground Floor Premises from
outside of the Building or to connect the Ground Floor Premises to the
Building's electricity supply (whichever is applicable, as provided in Paragraph
17.h. below), including, without limitation, the installation of a meter to
measure electricity consumed in the Ground Floor Premises so that Tenant can be
billed directly by the utility company for the electricity consumed in the
Ground Floor Premises. All such work shall be performed in accordance with
Paragraph 9 below, including, without limitation, in accordance with plans
reasonably approved by Landlord. Subject to Landlord's approval of the plans for
such work and Tenant's compliance with the other applicable provisions of
Paragraph 9 below, Landlord will permit Tenant, as a part of the Initial
Alterations, to install electrical equipment which provides to the Ground Floor
Premises 300 watts of electrical current per square foot of the Ground Floor
Premises. Paragraph 17.c. below contains additional provisions regarding the
installation by Tenant of certain non-standard electricity circuits in the
Premises.

                In no event shall Tenant or Tenant's Contractor be given access
to the Premises for purposes of constructing the Initial Alterations therein
until Tenant has delivered to Landlord certificates for the insurance required
in Paragraph 15.a. below and for the insurance required by Landlord (in
accordance with Landlord's construction procedures for the Building) for
Tenant's Contractor. If Landlord is prepared to deliver the Premises to Tenant
with the Ground Floor Demising Work completed, but Tenant is not given access to
the Premises for the purposes of constructing the Initial Alterations because
the insurance conditions of the immediately preceding sentence have not been
satisfied, then for purposes of Paragraphs 2.b. and 3.b. above, Landlord shall
be deemed to have delivered the Premises to Tenant with the Ground Floor
Demising Work completed on the date that Landlord was prepared to so deliver the
Premises to Tenant with the Ground Floor Demising Work Completed,
notwithstanding the fact that Tenant and Tenant's

                                       3

<PAGE>

Contractor are not permitted access for purposes of construction until the
aforementioned insurance requirements are satisfied.

                b. Alterations Allowance. Notwithstanding anything to the
contrary in Paragraph 9 of the Lease, Landlord shall provide Tenant with an
allowance of up to Two Million Seven Hundred Seven Thousand Nine Hundred Twenty
Dollars ($2,707,920.00)(the "Alterations Allowance") to be applied toward the
cost of the Initial Alterations, of which not more than Three Hundred Twenty
Eight Thousand Nine Hundred Twenty Dollars ($328,920.00) of the Alterations
Allowance may be applied to the Initial Alterations in the Ground Floor
Premises. Further, not more than One Hundred Sixty Seven Thousand Four Hundred
Nine Dollars ($167,409.00) of the Alterations Allowance may be applied to
Tenant's reasonable space planning, architectural and engineering costs for the
design of the Initial Alterations. No portion of the Alterations Allowance may
(A) be applied to the cost of equipment, trade fixtures, moving expenses,
furniture, signage, computer cabling or free rent, (B) be applied to any portion
of the Premises which is then the subject of a sublease, or (C) be used to
prepare any portion of the Premises for a proposed subtenant or assignee.
Further, Tenant shall not be entitled to receive (and Landlord shall have no
obligation to disburse) all or any portion of the Alterations Allowance if
Tenant is in default under the Lease at the time Tenant requests such
disbursement. Notwithstanding anything to the contrary in this Paragraph 4.b.,
the Alterations Allowance shall be available for disbursement pursuant to the
terms hereof only during the period commencing on the Commencement Date and
ending on December 1, 2005 (the "Allowance Availability Period"). Accordingly,
if any portion of the Alterations Allowance has not been utilized (and Tenant
has not submitted to Landlord invoices evidencing such costs) prior to
expiration of the Allowance Availability Period, such unused portion shall be
forfeited by Tenant.

                Landlord shall disburse the Alterations Allowance for the
Initial Alterations directly to Tenant's Contractor, or subcontractors, or to
Tenant as Landlord and Tenant may agree, in monthly installments. Landlord's
disbursements shall be conditioned upon Landlord's receipt of (I) invoices of
Tenant's Contractor furnished to Landlord by Tenant covering work actually
performed, construction in place and materials actually delivered to the site
(as may be applicable) describing in reasonable detail such work, construction
and/or materials, (II) conditional lien waivers executed by Tenant's Contractor,
subcontractors or suppliers, as applicable, for their portion of the work
covered by the requested disbursement, and (III) unconditional lien waivers
executed by Tenant's Contractor and the persons and entities performing the work
or supplying the materials covered by Landlord's previous disbursement for the
work or materials covered by such previous disbursements (all such waivers to be
in the form prescribed by California law). No payment will be made for materials
or supplies not on site. Landlord may withhold the amount of any and all
retention percentages provided for in original contracts or subcontracts until
expiration of the applicable lien periods or receipt of unconditional lien
waivers and full releases upon final payment (in the form prescribed by
California law) from Tenant's Contractor, subcontractors or suppliers, as
applicable.

                Tenant shall pay for all costs of the construction of the
Initial Alterations in excess of the Alterations Allowance. Based on the
estimated cost of the construction of the Initial Alterations (the "Estimated
Costs"), the pro rata share of the Estimated Costs payable by Landlord and
Tenant shall be determined and an appropriate percentage share established for
each (a "Share of Costs"). Tenant and Landlord shall fund the cost of the
construction of the Initial Alterations (including the applicable portion of the
applicable fees) as the same is performed, in accordance with their respective
Share of Costs for the construction. Tenant's payments shall be made directly to
Tenant's Contractor or the subcontractors or suppliers involved and Tenant shall
furnish to Landlord copies of receipted invoices for such payments (describing
in reasonable detail the work, construction and/or materials applicable to the
subject disbursement) and such waivers of lien rights as Landlord may reasonably
require.

                Notwithstanding anything to the contrary above, at the time
Landlord makes any disbursement of the Alterations Allowance for application to
the Initial Alterations, Landlord shall retain from the Alterations Allowance,
as a partial payment of the Alteration Operations Fee, a proportionate amount of
the Alteration Operations Fee based upon Landlord's reasonable estimation of the
amount required to be withheld from each disbursement in order to ensure that
the entire Alteration Operations Fee is retained over the course of construction
of the Initial Alterations on a prorata basis. At such time as the Alterations
Allowance has been entirely disbursed, Tenant shall, within fifteen (15) days of
written demand, pay to Landlord the remainder, if any, of the Alteration
Operations Fee not yet paid to Landlord.

            5.  Monthly Rent.

                a. Commencing as of the Commencement Date, and continuing
thereafter on or before the first day of each calendar month during the term
hereof, Tenant shall pay to Landlord, as monthly rent for the Premises, the
Monthly Rent specified in Paragraph 2 above. If Tenant's obligation to pay
Monthly Rent hereunder commences on a day other than the first day of a

                                       4

<PAGE>

calendar month, or if the term of this Lease terminates on a day other than the
last day of a calendar month, then the Monthly Rent payable for such partial
month shall be appropriately prorated on the basis of a thirty (30)-day month.
Monthly Rent and the Additional Rent specified in Paragraph 7 shall be paid by
Tenant to Landlord, in advance, without deduction, offset, prior notice or
demand, in immediately available funds of lawful money of the United States of
America, or by good check as described below, to the lockbox location designated
by Landlord, or to such other person or at such other place as Landlord may from
time to time designate in writing. Payments made by check must be drawn either
on a California financial institution or on a financial institution that is a
member of the federal reserve system. Notwithstanding the foregoing, Tenant
shall pay to Landlord together with Tenant's execution of this Lease an amount
equal to the Monthly Rent payable for the first full calendar month of the Lease
term after Tenant's obligation to pay Monthly Rent shall have commenced
hereunder, which amount shall be applied to the Monthly Rent first due and
payable hereunder.

                b. All amounts payable by Tenant to Landlord under this Lease,
or otherwise payable in connection with Tenant's occupancy of the Premises, in
addition to the Monthly Rent hereunder and Additional Rent under Paragraph 7,
shall constitute rent owed by Tenant to Landlord hereunder.

                c. Any rent not paid by Tenant to Landlord within three (3)
Business Days following written notice to Tenant that such sum is past due shall
bear interest from the date due to the date of payment by Tenant at an annual
rate of interest (the "Interest Rate") equal to the lesser of (i) twelve percent
(12%) per annum or (ii) the maximum annual interest rate allowed by law on such
due date for business loans (not primarily for personal, family or household
purposes) not exempt from the usury law; except that Landlord shall only be
required to give two (2) such notices in any calendar year, and after two (2)
such notices are given any failure by Tenant in such calendar year to pay
Monthly Rent, Additional Rent or any other amount due hereunder on the date due
will subject Tenant to the default interest at the Interest Rate, without the
requirement of notice from Landlord of such failure. Failure by Tenant to pay
rent when due, including any interest accrued under this subparagraph, shall
constitute an Event of Default (as defined in Paragraph 25 below) giving rise to
all the remedies afforded Landlord under this Lease and at law for nonpayment of
rent.

                d. No security or guaranty which may now or hereafter be
furnished to Landlord for the payment of rent due hereunder or for the
performance by Tenant of the other terms of this Lease shall in any way be a bar
or defense to any of Landlord's remedies under this Lease or at law.

            6.  Security Deposit. Upon execution of this Lease, Tenant shall pay
to Landlord the Security Deposit specified in Paragraph 2.d. above as security
for Tenant's performance of all of Tenant's covenants and obligations under this
Lease; provided, however, that the Security Deposit is not an advance rent
deposit or an advance payment of any other kind, nor a measure of Landlord's
damages upon Tenant's default. Landlord shall not be required to segregate the
Security Deposit from its other funds and no interest shall accrue or be payable
to Tenant with respect thereto. Landlord may (but shall not be required to) use
the Security Deposit or any portion thereof to cure any Event of Default or to
compensate Landlord for any damage Landlord incurs as a result of Tenant's
failure to perform any of its covenants or obligations hereunder, it being
understood that any use of the Security Deposit shall not constitute a bar or
defense to any of Landlord's remedies under this Lease or at law. In such event
and upon written notice from Landlord to Tenant specifying the amount of the
Security Deposit so utilized by Landlord and the particular purpose for which
such amount was applied, Tenant shall within five (5) Business Days of
Landlord's written request deposit with Landlord an amount sufficient to return
the Security Deposit to an amount equal to one hundred ten percent (110%) of the
amount specified in Paragraph 2.d. as the same may have been increased by prior
applications of this Paragraph 6 (provided that the first time Landlord applies
all or part of the Security Deposit to Tenant's obligations, Tenant shall only
be required to restore the Security Deposit to 100% of the amount specified in
Paragraph 2.d.). Tenant's failure to make such payment to Landlord within five
(5) Business Days of Landlord's written notice shall constitute an Event of
Default. Within thirty (30) days following the expiration or termination of this
Lease, Landlord shall return to Tenant the Security Deposit or the balance
thereof then held by Landlord, after any deductions therefrom reasonably made by
Landlord to cure any default of Tenant under this Lease; provided, however, that
in no event shall any such return be construed as an admission by Landlord that
Tenant has performed all of its covenants and obligations hereunder. No holder
of a Superior Interest (as defined in Paragraph 21 below), nor any purchaser at
any judicial or private foreclosure sale of the Real Property or any portion
thereof, shall be responsible to Tenant for the Security Deposit unless and only
to the extent such holder or purchaser shall have actually received the same.

            7.  Additional Rent: Increases in Operating Expenses and Tax
Expenses.

                a. Operating Expenses. Tenant shall pay to Landlord, at the
times hereinafter set forth, Tenant's Share, as specified in Paragraph 2.e.
above, of any increase in the Operating Expenses (as defined below) incurred by
Landlord in each calendar year subsequent to the Base Year specified in
Paragraph 2.f. above, over the Operating Expenses incurred by Landlord during
the Base Year. The amounts payable under this Paragraph 7.a. and Paragraph 7.b.
below are termed "Additional Rent" herein. Additional Rent under this Paragraph
7.a. shall be separately calculated for the Ground Floor Premises and the 4th
and 5th Floor Premises due to the fact that, as provided in the immediately
following grammatical paragraph, certain of the Operating Expenses are not
applicable to the Ground Floor Premises.

                The term "Operating Expenses" shall mean the total costs and
expenses reasonably incurred by Landlord in connection with the management,
operation, maintenance, repair and ownership of the Real Property, including,
without limitation, the following costs: (1) salaries, wages, bonuses and other
compensation (including hospitalization, medical, surgical, retirement plan,
pension plan, union dues, life insurance, including group life insurance,
welfare and other fringe benefits, and vacation, holidays and other paid absence
benefits) relating to employees of Landlord or its agents engaged in the
operation, repair, or maintenance of the Real Property; (2) payroll, social
security, workers' compensation, unemployment and similar taxes with respect to
such employees of Landlord or its agents, and the cost of providing disability
or other benefits imposed by law or otherwise, with respect to such employees;
(3) the cost of uniforms (including the cleaning, replacement and pressing
thereof) provided to such employees; (4) premiums and other charges incurred by
Landlord with respect to fire, other casualty, rent and liability insurance, any
other insurance as is deemed necessary or advisable in the reasonable judgment
of Landlord, or any insurance required by the holder of any Superior Interest
(as defined in Paragraph 21 below), and, after the Base Year, costs of repairing
an insured casualty to the extent of the deductible amount under the applicable
insurance policy (provided, however, that if the cost of any such insurance for
the Base Year is greater than the cost of such insurance in subsequent year(s)
of the Lease term due to unusual increases or fluctuations in the rate or scope
of such insurance in the Base Year and such unusual increases or fluctuations
are not present in the applicable subsequent year(s), Operating Expenses for the
Base Year may be adjusted, for purposes of determining the Operating Expenses
payable by Tenant in the applicable subsequent year(s), to reflect what the cost
of such insurance would have been in the Base Year had the normal rates and
scope of service applied); (5) water charges and sewer rents or fees; (6)
license, permit and inspection fees other than as described in clause (viii) of
the immediately following grammatical paragraph; (7) sales, use and excise taxes
on goods and services purchased by Landlord in connection with the operation,
maintenance or repair of the Real Property and Building systems and equipment;
(8) telephone, telegraph, postage, stationery supplies and other expenses
incurred in connection with the operation, maintenance, or repair of the Real
Property; (9) management fees and expenses; (10) costs of repairs to and
maintenance of the Real Property, including Building systems and appurtenances
thereto and normal repair and replacement of worn-out equipment, facilities and
installations, but excluding the replacement of major Building systems (except
to the extent provided in (16) and (17) below); (11) fees and expenses for
janitorial (excluding, as to the Operating Expenses attributable to the Ground
Floor Premises, janitorial services provided to premises leased to tenants),
window cleaning, guard, extermination, water treatment, rubbish removal,
plumbing and other services and inspection or service contracts for elevator,
electrical, mechanical, HVAC (excluding, as to the Operating Expenses
attributable to the Ground Floor Premises, fees and expenses for the HVAC system
that services premises leased to tenants) and other building equipment and
systems or as may otherwise be necessary or proper for the operation, repair or
maintenance of the Real Property (provided, however, that if the cost of any
such service for the Base Year is greater than the cost of such service in
subsequent year(s) of the Lease term due to unusual increases or fluctuations in
the rate or scope of such service in the Base Year and such unusual increases or
fluctuations are not present in the applicable subsequent year(s), Operating
Expenses for the Base Year may be adjusted, for purposes of determining the
Operating Expenses payable by Tenant in the applicable subsequent year(s), to
reflect what the cost of such service would have been in the Base Year had the
normal rates and scope of service applied); (12) costs of supplies, tools,
materials, and equipment used in connection with the operation, maintenance or
repair of the Real Property, properly allocated between the Real Property and
any other properties for which the same are also used; (13) accounting, legal
and other professional fees and expenses; (14) fees and expenses for painting
the exterior or the public or common areas of the Building and the cost of
maintaining the sidewalks, landscaping and other common areas of the Real
Property; (15) costs and expenses for electricity, chilled water, air
conditioning, water for heating, gas, fuel, steam, heat, lights, power and other
energy related utilities required in connection with the operation, maintenance
and repair of the Real Property (excluding, as to the Operating Expenses
attributable to the Ground Floor Premises, such services provided to premises
leased to tenants) (provided, however, that if the cost of any energy related
utility for the Base Year is greater than the cost of such utility in subsequent
year(s) of the Lease term due to unusual increases or fluctuations in the rate
for such utility in the Base Year and such unusual increases or fluctuations are
not present in the applicable

                                       6

<PAGE>

subsequent year(s), Operating Expenses for the Base Year may be adjusted, for
purposes of determining the Operating Expenses payable by Tenant in the
applicable subsequent year(s), to reflect what the cost of such utility would
have been in the Base Year had normal rates applied); (16) the cost of any
capital improvements made by Landlord to the Real Property or capital assets
acquired by Landlord after the Base Year in order to comply with any local,
state or federal law, ordinance, rule, regulation, code or order of any
governmental entity or insurance requirement (collectively, "Legal Requirement")
with which the Real Property was not required to comply during the Base Year, or
to comply with any amendment or other change to the enactment or interpretation
of any Legal Requirement from its enactment or interpretation during the Base
Year; (17) the cost of any capital improvements made by Landlord to the Building
or capital assets acquired by Landlord after the Base Year for the protection of
the health and safety of the occupants of the Real Property or that are designed
to reduce other Operating Expenses (provided, however, that, with regard to
capital improvements or assets designed to reduce other Operating Expenses, the
costs thereof may only be included in Operating Expenses if, at the time such
costs were incurred, Landlord reasonably estimated (and upon Tenant's written
request, Landlord shall deliver to Tenant a written statement and explanation of
Landlord's estimation) that the annual saving in Operating Expenses that would
result from such expenditure would be equal to or exceed the annual amortized
amount of the cost to be included in Operating Expenses pursuant to this
Paragraph 7.a.); (18) the cost of furniture, draperies, carpeting, landscaping
and other customary and ordinary items of personal property (excluding
paintings, sculptures and other works of art) provided by Landlord for use in
common areas of the Building or the Real Property or in the Building office (to
the extent that such Building office is dedicated to the operation and
management of the Real Property); provided, however, that leasing or rental
costs of a rotating or other art program for the common areas of the Building or
the Real Property shall be included in Operating Expenses; and (19) Building
office (excluding any portion of such office that is used exclusively for
leasing purposes) rent or rental value, not to exceed fair market rent or rental
value for more than 3,000 rentable square feet of space. If the Real Property
becomes subject to any covenants, conditions or restrictions, reciprocal
easement agreement, common area declaration or similar agreement, the foregoing
common area expenses shall include all fees, costs or other expenses allocated
to the Real Property under such agreement. With respect to the costs of items
included in Operating Expenses under (16) and (17), such costs shall be
amortized over a reasonable period, as determined by Landlord in accordance with
generally accepted property management practices, together with interest on the
unamortized balance at a rate per annum equal to three (3) percentage points
over the six-month United States Treasury bill rate in effect at the time such
item is constructed or acquired, or at such higher rate as may have been paid by
Landlord on funds borrowed for the purpose of constructing or acquiring such
item, but in either case not more than the maximum rate permitted by law at the
time such item is constructed or acquired.

                Operating Expenses shall not include the following: (i)
depreciation on the Building or equipment or systems therein; (ii) debt service;
(iii) rental under any ground or underlying lease; (iv) interest (except as
expressly provided in this Paragraph 7.a.); (v) Tax Expenses (as defined in
Paragraph 7.b. below); (vi) attorneys' and other professionals' fees and
expenses incurred in connection with lease enforcement, lease disputes or lease
negotiations with prospective, former or current Building tenants or in
connection with the defense of Landlord's title or interest in the Real Property
or Landlord's sale, purchase or financing thereof; (vii) the cost (including any
amortization thereof) of any improvements, alterations or equipment which would
be properly classified as capital expenditures according to generally accepted
property management practices (except to the extent expressly included in
Operating Expenses pursuant to this Paragraph 7.a.); (viii) the cost of
decorating, improving for tenant occupancy, painting or redecorating portions of
the Building to be demised to tenants (including architectural and engineering
fees, and license, permit and inspection fees, in connection therewith) and the
cost of tenant concessions granted by Landlord in connection with leasing space
in the Building (such as free rent, lease takeover payments and improvement
allowances); (ix) wages, salaries, benefits or other similar compensation paid
to executive employees of Landlord or Landlord's agents above the rank of
regional property manager or the cost of labor and employees with respect to
personnel not located at the Building on a full-time basis unless such costs are
appropriately allocated between the Building and the other responsibilities of
such personnel; (x) advertising and other promotional expenses; (xi) real estate
broker's or other leasing commissions; (xii) penalties or other costs incurred
due to a violation by Landlord, as determined by written admission, stipulation,
final judgment or arbitration award, of any of the terms and conditions of this
Lease or any other lease or contract relating to the Building except to the
extent such costs reflect costs that would have been incurred by Landlord absent
such violation; (xiii) rentals and other related expenses incurred in leasing
air conditioning systems, elevators or other equipment ordinarily considered to
be of a capital nature (except equipment that is not affixed to the Building and
is used in providing janitorial services, and except to the extent such costs
would otherwise be includable pursuant to items (16) and (17) as set forth in
the immediately preceding paragraph); (xiv) the cost of any Hazardous Materials
(as defined in Paragraph 8.c.) abatement or removal activities; provided,
however, that Operating Expenses may include the costs attributable to those
actions taken by Landlord to comply with any Legal Requirements in connection
with the ordinary operation and maintenance of the Building, including costs
incurred in removing limited amounts of Hazardous

                                       7

<PAGE>

Materials from the Building when such removal is directly related to such
ordinary maintenance and operation; (xv) any expense to the extent Landlord is
entitled to be reimbursed by a tenant or other party (other than through a
provision similar to the first paragraph of this Paragraph 7.a.); (xvi) fines,
penalties and other costs incurred due to a violation by Landlord of any Legal
Requirements where Landlord shall have failed to cure such violation after
written notice thereof and where compliance with such law is Landlord's
obligation pursuant to this Lease, except to the extent such fines or penalties
would have been incurred by Landlord absent such violation; (xvii) all direct
costs of refinancing, selling, exchanging or otherwise transferring ownership of
the Building or the Real Property or any interest therein or portion thereof,
including broker commissions, attorneys' fees and closing costs, but expressly
excluding any increases in Tax Expenses; (xviii) charitable and political
contributions; (xix) reserves for bad debts, rent loss, capital items or future
Operating Expenses (other than payments pursuant to Paragraph 7.e. or similar
provisions in other tenants' leases, which payments shall not be deemed
reserves); (xx) costs of compliance with applicable building codes to the extent
the Building does not comply with such building codes as of the expiration of
the Base Year and such compliance is required as of the expiration of the Base
Year; (xxi) costs of compliance with the Americans with Disabilities Act as
currently in effect and interpreted, to the extent the Building does not comply
therewith as of the expiration of the Base Year and such compliance is required
as of the expiration of the Base Year; (xxii) costs of major Building signage
which identifies a tenant other than Tenant; (xxiii) third party claims paid by
Landlord for personal injury or property damage which result from the gross
negligence or willful misconduct of Landlord or its agents, including costs of
Landlord's defense thereof, except that the foregoing shall not relieve Tenant
of responsibility for claims (and the defense costs thereof) for which Tenant is
responsible pursuant to Paragraph 14 or any other provision of this Lease;
(xxiv) electric power costs or costs for other utilities for which any tenant
(including Tenant) directly contracts with a public service company, or any
costs (including surcharges) for electricity, water, heat, air conditioning or
other utilities provided by Landlord to any tenant free of charge in excess of
the costs for utilities offered by Landlord to Tenant free of charge or (xxv) if
Landlord did not carry a particular type of insurance (or a policy similar
thereto) during the Base Year, notwithstanding the fact that such insurance was
typically carried by operators of first class office buildings in downtown
Oakland during the Base Year, and Landlord obtains such insurance ("New
Insurance") subsequent to the Base Year, then the initial annual premium for the
New Insurance shall not be included in Operating Expenses, and Operating
Expenses in any given year subsequent to the first calendar year in which
Landlord obtains the New Insurance shall include only the increases in the
annual premium over the annual premium paid for the New Insurance for the first
calendar year after the Base Year in which Landlord carries the New Insurance.

                b. Tax Expenses. Tenant shall pay to Landlord as Additional Rent
under this Lease, at the times hereinafter set forth, Tenant's Share, as
specified in Paragraph 2.e. above, of any increase in Tax Expenses (as defined
below) incurred by Landlord in each calendar year subsequent to the Base Tax
Year specified in Paragraph 2.f. above, over Tax Expenses incurred by Landlord
during the Base Tax Year. Notwithstanding the foregoing, if, during the Base Tax
Year, less than one hundred percent (100%) of the base building improvements
were completed and/or less than ninety percent (90%) of the initial tenant
improvements for the Building were completed, then the Tax Expenses for the Base
Tax Year shall be adjusted to be what they would have been if the Real Property
and the Building had been assessed for the Base Tax Year with one hundred
percent (100%) of the base building improvements completed and ninety percent
(90%) of the initial tenant improvements completed. Notwithstanding the
foregoing, if any reassessment, reduction or recalculation of any item included
in Tax Expenses during the term results in a reduction of Tax Expenses for the
Base Tax Year, then for purposes of calculating Tenant's Share of increases in
Tax Expenses from and after the Base Tax Year, Tax Expenses for the Base Tax
Year shall be adjusted to reflect such reduction and shall be the actual amount
of the Tax Expenses for the Base Tax Year, after application of such reduction.
Further, if a particular Tax Expense may be legally paid in installments over
time without fine, added interest or penalty, then, for purposes of applying
this Paragraph 7.b., Landlord shall be deemed to have paid such Tax Expense in
the maximum number of installments over the longest term so allowed.

            The term "Tax Expenses" shall mean all taxes, assessments (whether
general or special), excises, transit charges, housing fund assessments or other
housing charges, improvement districts, levies or fees, ordinary or
extraordinary, unforeseen as well as foreseen, of any kind, which are assessed,
levied, charged, confirmed or imposed on the Real Property, on Landlord with
respect to the Real Property, on the act of entering into leases of space in the
Real Property, on the use or occupancy of the Real Property or any part thereof,
with respect to services or utilities consumed in the use, occupancy or
operation of the Real Property, on any improvements, fixtures and equipment and
other personal property of Landlord located in the Real Property and used in
connection with the operation of the Real Property, or on or measured by the
rent payable under this Lease or in connection with the business of renting
space in the Real Property, including, without limitation, any gross income tax
or excise tax levied with respect to the receipt of such rent, by the United
States of America, the State of California, the City of Oakland, the County of
Alameda, any political

                                       8

<PAGE>

subdivision, public corporation, district or other political or public entity or
public authority, and shall also include any other tax, fee or other excise,
however described, which may be levied or assessed in lieu of, as a substitute
(in whole or in part) for, or as an addition to, any other Tax Expense. Tax
Expenses shall include reasonable attorneys' and professional fees, costs and
disbursements incurred in connection with proceedings to contest, determine or
reduce Tax Expenses, but shall exclude all penalties, fines, interest and late
charges for failure to timely pay Tax Expenses, except for any failure caused by
Tenant's failure to timely pay its share of Tax Expenses. If it shall not be
lawful for Tenant to reimburse Landlord for any increase in Tax Expenses as
defined herein, the Monthly Rent payable to Landlord prior to the imposition of
such increases in Tax Expenses shall be increased to net Landlord the same net
Monthly Rent after imposition of such increases in Tax Expenses as would have
been received by Landlord prior to the imposition of such increases in Tax
Expenses.

            Tax Expenses shall not include taxes imposed on land and
improvements other than the Realty Property, income, franchise, transfer,
inheritance, gift, estate or capital stock taxes, unless, due to a change in the
method of taxation, any of such taxes is levied or assessed against Landlord in
lieu of, as a substitute (in whole or in part) for, or as an addition to, any
other charge which would otherwise constitute a Tax Expense.

                c. Adjustment for Occupancy Factor. Notwithstanding any other
provision herein to the contrary, in the event the Building is not fully
occupied during any calendar year during the term after the Base Year, an
adjustment shall be made by Landlord in computing Operating Expenses for such
year so that the Operating Expenses shall be computed for such year as though
the Building had been fully occupied during such year. In addition, if any
particular work or service includable in Operating Expenses is not furnished to
a tenant who has undertaken to perform such work or service itself, Operating
Expenses shall be deemed to be increased by an amount equal to the additional
Operating Expenses which would have been incurred if Landlord had furnished such
work or service to such tenant. The parties agree that statements in this Lease
to the effect that Landlord is to perform certain of its obligations hereunder
at its own or sole cost and expense shall not be interpreted as excluding any
cost from Operating Expenses or Tax Expenses if such cost is an Operating
Expense or Tax Expense pursuant to the terms of this Lease. Notwithstanding
anything to the contrary herein, Landlord shall (i) not make a profit by
charging items to Operating Expenses that are otherwise also charged separately
to others and (ii) not collect Operating Expenses with respect to any calendar
year from Tenant and the other tenants/occupants in the Building in an amount
which, when added to the amounts paid by Landlord for Operating Expenses in the
respective Base Years hereunder and under the leases of such other
tenants/occupants, exceeds the amount actually incurred by Landlord for
Operating Expenses with respect to the applicable calendar year.

                d. Intention Regarding Expense Pass-Through. It is the intention
of Landlord and Tenant that, except as may be expressly provided herein, the
Monthly Rent paid to Landlord throughout the term of this Lease shall be
absolutely net of all increases, respectively, in Tax Expenses and Operating
Expenses over, respectively, Tax Expenses for the Base Tax Year and Operating
Expenses for the Base Year, and the foregoing provisions of this Paragraph 7 are
intended to so provide.

                e. Notice and Payment. On or before the first day of each
calendar year during the term hereof, or as soon as practicable thereafter,
Landlord shall give to Tenant notice of Landlord's estimate of the Additional
Rent, if any, payable by Tenant pursuant to Paragraphs 7.a. and 7.b. for such
calendar year. On or before the first day of each month during each such
calendar year, Tenant shall pay to Landlord one-twelfth (1/12th) of the
estimated Additional Rent; provided, however, that if Landlord's notice is not
given at least thirty (30) days prior to the first day of any calendar year
Tenant shall continue to pay Additional Rent on the basis of the prior year's
estimate until the first month which commences at least thirty (30) days after
Landlord's notice is given. If at any time it appears to Landlord that the
Additional Rent payable under Paragraphs 7.a. and/or 7.b. will vary from
Landlord's estimate by more than five percent (5%), Landlord may, by thirty (30)
days' prior written notice to Tenant, revise its estimate for such year, and
subsequent payments by Tenant for such year shall be based upon the revised
estimate. On the first monthly payment date at least thirty (30) days after any
new estimate is delivered to Tenant, Tenant shall also pay any accrued cost
increases, based on such new estimate.

                f. Annual Accounting. Landlord shall maintain true, correct and
complete records of the Operating Expenses and Tax Expenses in accordance with
generally accepted accounting principles, consistently applied. Within one
hundred twenty (120) days after the close of each calendar year, or as soon
after such one hundred twenty (120) day period as practicable, but in any event
within one hundred eighty (180) days after the close of each calendar year,
Landlord shall deliver to Tenant a statement of the Additional Rent payable
under Paragraphs 7.a. and 7.b. for such year. The statement shall be based on
the results of an audit of the operations of the Building prepared for the
applicable year by a nationally recognized certified public accounting firm
selected by Landlord and shall be accompanied by a copy of the auditor's
statement on which Landlord's

                                       9

<PAGE>

annual statement is based. Upon Tenant's request made no later than thirty (30)
days after Tenant's receipt of Landlord's annual statement, Landlord shall
promptly deliver to Tenant such other information regarding the annual statement
as may be reasonably required by Tenant to ascertain Landlord's compliance with
this Paragraph 7. If the annual statement shows that Tenant's payments of
Additional Rent for such calendar year pursuant to Paragraph 7.e. above exceeded
Tenant's obligations for the calendar year, Landlord shall credit the excess to
the next succeeding installments of estimated Additional Rent, or if no further
installment of estimated Additional Rent is due from Tenant, reimburse the
excess directly to Tenant. If the annual statement shows that Tenant's payments
of Additional Rent for such calendar year pursuant to Paragraph 7.e. above were
less than Tenant's obligation for the calendar year, Tenant shall pay the
deficiency to Landlord within thirty (30) days after delivery of such statement.

            Landlord's annual statement shall be final and binding upon Landlord
and Tenant unless Tenant shall contest in writing to Landlord any item therein,
or Landlord shall advise Tenant in writing of any correction thereto (whether
due to a reassessment or otherwise), within six (6) months after Tenant's
receipt of the annual statement, which writing shall specify each item contested
or corrected (as applicable) and the reason therefor. If Tenant has received a
written correction from Landlord pursuant to the immediately preceding sentence,
then Tenant shall have until the later of sixty (60) days from receipt of such
written correction or the expiration of the six (6) month period provided for in
the immediately preceding sentence, to contest such writing by written notice to
Landlord, and, if no such written notice is given within the applicable period,
the correction notice shall be binding on the parties. Notwithstanding the
foregoing, the Tax Expenses included in any annual statement may be modified by
any subsequent adjustment or retroactive application of Tax Expenses affecting
the calculation of such Tax Expenses. If Tenant timely delivers a written notice
to Landlord contesting an annual statement or written correction, Landlord and
Tenant shall endeavor in good faith to resolve the issues raised by Tenant's
contest notice. Paragraph 7.g. below provides Tenant with specific audit rights
in connection with Tenant's contest of the annual statement.

                g. Audit Rights. If Tenant timely exercised its right to contest
an annual statement under the second grammatical paragraph of Paragraph 7.f.
above, Tenant shall have the right to cause a nationally recognized independent
certified public accountant designated by Tenant, to be paid on an hourly and
not a contingent fee basis, to audit the items questioned by Tenant in its
original notice contesting the annual statement, provided that Tenant (i)
notifies Landlord in writing of Tenant's intention to exercise such audit right
within thirty (30) days following the expiration of the time period provided for
in the second grammatical paragraph of Paragraph 7.f. above for Tenant to
contest the annual statement, (ii) actually begins such audit within thirty (30)
days after the notice from Tenant to Landlord advising Landlord that Tenant will
require an audit (provided that such 30-day period within which the audit must
be commenced shall be extended by the length of any delay in the commencement of
the audit that is caused by Landlord) and (iii) diligently pursues such audit to
completion as quickly as reasonably possible. Landlord agrees to make available
to Tenant's auditors, at Landlord's office in San Francisco and/or at Landlord's
office in the Building (at Landlord's sole option), the books and records
relevant to the audit for review and copying, but such books and records may not
be removed from Landlord's offices. Tenant shall bear all costs of such audit,
including Landlord's actual copying costs and personnel costs, if any incurred
in connection with such audit (provided that, prior to incurring any personnel
costs in connection with any such audit, Landlord shall advise Tenant of
Landlord's anticipated personnel costs so that Tenant may, at Tenant's option,
modify Tenant's activities with regard to such audit in order to preclude the
need for Landlord to incur such personnel costs), except that, if the audit (as
conducted and certified by the auditor) shows an aggregate overstatement of
Operating Expenses of five (5%) or more, and Landlord's auditors concur in such
findings (or, in the absence of such concurrence, such overstatement is
confirmed by a court of competent jurisdiction or such other dispute resolution
mechanism as to which the parties mutually agree in writing), then Landlord
shall bear all costs of the audit. If the agreed or confirmed audit shows an
underpayment of Operating Expenses by Tenant, Tenant shall pay to Landlord,
within thirty (30) days after the audit is agreed to or confirmed, the amount
owed to Landlord, and, if the agreed or confirmed audit shows an overpayment of
Operating Expenses by Tenant, Landlord shall reimburse Tenant for such
overpayment within thirty (30) days after the audit is agreed to or confirmed.

            Notwithstanding anything to the contrary set forth above, Tenant's
audit rights under this Paragraph 7.g. shall be conditioned upon (i) Tenant
having paid the total amounts billed by Landlord under this Paragraph 7 within
the time stipulated in Paragraph 7.e. for payment (including, without
limitation, the contested amounts) and (ii) Tenant executing, prior to the
commencement of the audit, a confidentiality agreement in form and substance
reasonably satisfactory to Landlord in which Tenant shall agree to keep
confidential, and not disclose to any other party, the results of any such audit
or any action taken by Landlord in response thereto.

                h. Proration for Partial Lease Year. If this Lease commences on
a day other than the first day of a calendar year or terminates on a day other
than the last day of a calendar year, the Additional Rent payable by Tenant
pursuant to this Paragraph 7 applicable to such partial calendar year shall be
prorated on the basis that the number of days of such partial calendar year
bears to three hundred sixty (360).

            8.  Use of Premises; Compliance with Law.

                a. Use of Premises. The Premises may be used solely for general
office purposes for the initially contemplated use by Tenant described in
Paragraph 2.g. above (provided that the Ground Floor Premises may also be used
as a computer data center) or for any other general office use consistent with
the operation of the Building as a first-class office building provided in no
event may the use of the Premises be changed to (1) a use which materially
increases (a) the operating costs for the Building, (b) the burden on the
Building services, or (c) the foot traffic, elevator usage or security concerns
in the Building, or which creates an increased probability of the comfort and/or
safety of the Landlord or other tenants of the Building being compromised or
reduced, or (2) use as a school or training facility, an entertainment, sports
or recreation facility, retail sales to the public (except that the Ground Floor
Premises may be used for a computer data center or for retail purposes
appropriate for a first class office/retail project and appropriate for the
Ground Floor Premises based on the then tenant mix in the retail areas of the
Building, as reasonably determined by Landlord), a personnel or employment
agency, an office or facility of any governmental or quasi-governmental agency
or authority which is inconsistent with the first-class character of the
Building, a place of public assembly (including without limitation a meeting
center, theater or public forum), any use by or affiliation with a foreign
government (including without limitation an embassy or consulate or similar
office), or a facility for the provision of social, welfare or clinical health
services or sleeping accommodations (whether temporary, daytime or overnight),
or (3) a use which may conflict with any exclusive uses granted to other tenants
of the Real Property, or with the terms of any easement, covenant, condition or
restriction, or other agreement affecting the Real Property.

            Tenant shall not do or suffer or permit anything to be done in or
about the Premises or the Real Property, nor bring or keep anything therein,
which would in any way subject Landlord, Landlord's agents or the holder of any
Superior Interest (as defined in Paragraph 21) to any liability, increase the
premium rate of or affect any fire, casualty, liability, rent or other insurance
relating to the Real Property or any of the contents of the Building, or cause a
cancellation of, or give rise to any defense by the insurer to any claim under,
or conflict with, any policies for such insurance. If any act or omission of
Tenant results in any such increase in premium rates, Tenant shall pay to
Landlord within thirty (30) days after demand the amount of such increase.
Tenant shall not do or suffer or permit anything to be done in or about the
Premises or the Real Property which will in any way obstruct or interfere with
the rights of other tenants or occupants of the Building or injure or annoy
them, or use or suffer or permit the Premises to be used for any immoral or
unlawful purpose, nor shall Tenant cause, maintain, suffer or permit any
nuisance in, on or about the Premises or the Real Property. Without limiting the
foregoing, no loudspeakers or other similar device which can be heard outside
the Premises shall, without the prior written approval of Landlord, be used in
or about the Premises. Tenant shall not commit or suffer to be committed any
waste in, to or about the Premises. Landlord may from time to time conduct fire
and life safety training for tenants of the Building, including evacuation
drills and similar procedures. Tenant agrees to participate in such activities
as reasonably requested by Landlord.

            Tenant acknowledges that many of the functions necessary to operate
the Building are performed by union personnel. Tenant shall immediately
terminate the engagement or employment of the person, entity or contractor whose
presence causes a labor or other disturbance at the Building and either engage
or employ a replacement person, entity or contractor whose presence will not
cause such a disturbance or terminate the relevant work. Landlord will advise
Tenant, upon request, as to whether a given person, entity or contractor, in
Landlord's reasonable judgment, is likely to cause a labor or other disturbance.

                b. Compliance with Law. Tenant shall not do or permit anything
to be done in or about the Premises which will in any way conflict with any
Legal Requirement (as defined in Paragraph 7.a.(16) above) now in force or which
may hereafter be enacted. Except as set forth in this Lease, Tenant, at its sole
cost and expense, shall promptly comply with all such present and future Legal
Requirements relating to the condition, use or occupancy of the Premises, and
shall perform all work to the Premises or other portions of the Real Property
required to effect such compliance (or, at Landlord's election, Landlord may
perform such work at Tenant's cost). Notwithstanding the foregoing, however,
Tenant shall not be required to perform any changes to the Base Building (as
defined below) unless such changes are related to or affected or triggered by
(i) Tenant's Alterations (as defined in Paragraph 9 below), including, without
limitation, the Initial Alterations, (ii) Tenant's particular use of the
Premises (as opposed to Tenant's use of the Premises for general office purposes
in a normal and customary manner), or (iii) Tenant's particular employees

                                       11

<PAGE>

or employment practices. The judgment of any court of competent jurisdiction or
the admission of Tenant in an action against Tenant, whether or not Landlord is
a party thereto, that Tenant has violated any Legal Requirement shall be
conclusive of that fact as between Landlord and Tenant. Tenant shall immediately
furnish Landlord with any notices received from any insurance company or
governmental agency or inspection bureau regarding any unsafe or unlawful
conditions within the Premises or the violation of any Legal Requirement. "Base
Building" means the structural portions of the Building and the garage
(including exterior walls, roof, foundation, floor slabs and core of the
Building and the garage), all Building systems, including, without limitation,
elevator, plumbing, air conditioning, heating, electrical, security, life safety
and power, except those special or supplemental systems (including equipment
used in connection therewith) and non-Building standard lighting and electrical
wiring installed specifically for Tenant or any other tenants and the portion of
any other Building system within the Premises or any other specific tenant space
the maintenance, repair or compliance of which is the responsibility of Tenant
or such tenant, respectively.

                c. Hazardous Materials. Tenant shall not cause or permit the
storage, use, generation, release, handling or disposal (collectively,
"Handling") of any Hazardous Materials (as defined below), in, on, or about the
Premises or the Real Property by Tenant or any agents, employees, contractors,
licensees, subtenants, customers, guests or invitees of Tenant (collectively
with Tenant, "Tenant Parties"), except that Tenant shall be permitted to use (i)
diesel fuel in connection with its use of the Generator in accordance with
Paragraph 55 below, (ii) chemically-based fire prevention systems or electrical
static discharge wax in the computer data center and (iii) normal quantities of
office supplies or products (such as copier fluids or cleaning supplies)
customarily used in the conduct of general business office activities ("Common
Office Chemicals"), provided that the Handling of such Common Office Chemicals
shall comply at all times with all Legal Requirements, including Hazardous
Materials Laws (as defined below). Notwithstanding anything to the contrary
contained herein, however, in no event shall Tenant permit any usage of Common
Office Chemicals in a manner that may cause the Premises or the Real Property to
be contaminated by any Hazardous Materials or in violation of any Hazardous
Materials Laws. Tenant shall immediately advise Landlord in writing of (a) any
and all enforcement, cleanup, remedial, removal, or other governmental or
regulatory actions instituted, completed, or threatened pursuant to any
Hazardous Materials Laws relating to any Hazardous Materials affecting the
Premises; and (b) all claims made or threatened by any third party against
Tenant, Landlord, the Premises or the Real Property relating to damage,
contribution, cost recovery, compensation, loss, or injury resulting from any
Hazardous Materials on or about the Premises. Without Landlord's prior written
consent, Tenant shall not take any remedial action (other than as necessitated
by an emergency, in which case Tenant shall give Landlord verbal notice as soon
as possible under the circumstances so that Landlord can participate in the
remedial action, if possible under the circumstances, with written notice from
Tenant to Landlord to follow within one (1) Business Day of the remedial action,
describing the emergency and the action taken) or enter into any agreements or
settlements in response to the presence of any Hazardous Materials in, on, or
about the Premises. Tenant shall be solely responsible for and shall indemnify,
defend and hold Landlord and all other Indemnitees (as defined in Paragraph
14.b. below), harmless from and against all Claims (as defined in Paragraph
14.b. below), arising out of or in connection with, or otherwise relating to (i)
any Handling of Hazardous Materials by any Tenant Party or Tenant's breach of
its obligations hereunder, or (ii) any removal, cleanup, or restoration work and
materials necessary to return the Real Property or any other property of
whatever nature located on the Real Property to their condition existing prior
to the Handling of Hazardous Materials in, on or about the Premises by any
Tenant Party. Tenant's and Landlord's obligations under this Paragraph 8 shall
survive the expiration or other termination of this Lease. For purposes of this
Lease, "Hazardous Materials" means any explosive, radioactive materials,
hazardous wastes, or hazardous substances, including without limitation asbestos
containing materials, PCB's, CFC's, or substances defined as "hazardous
substances" in the Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended, 42 U.S.C. Section 9601-9657; the Hazardous
Materials Transportation Act of 1975, 49 U.S.C. Section 1801-1812; the Resource
Conservation and Recovery Act of 1976, 42 U.S.C. Section 6901-6987; or any other
Legal Requirement regulating, relating to, or imposing liability or standards of
conduct concerning any such materials or substances now or at any time hereafter
in effect (collectively, "Hazardous Materials Laws").

            d.  Landlord's representations and Warranties. Landlord represents
and warrants to Tenant as follows:

                (i) To the best of Landlord's knowledge (which, for purposes
hereof, shall be limited to the actual knowledge of Shorenstein Realty Services,
L.P., a California limited partnership, the manager of Landlord ("Manager"), and
Manager's officers and employees, and to no constituent owners of Landlord), the
Real Property is in compliance with and, as of the date Landlord delivers the
Premises to Tenant, will be in compliance with all Hazardous Materials Laws;

                                       12

<PAGE>

                (ii) Throughout the term of this Lease Landlord shall comply
with all Hazardous Materials laws applicable to the operation of the Real
Property; provided, however, that (a) the foregoing shall not be deemed to
discharge Tenant from its obligations set forth in this Paragraph 8 or elsewhere
in this Lease, and (b) in no event shall the foregoing prohibit Landlord from
including in Operating Expenses any costs relating to such compliance that would
otherwise be included in Operating Expenses under Paragraph 7.a. above; and

                (iii) The Base Building presently complies, and will comply, as
of the date Landlord delivers the Premises to Tenant, with all Legal
Requirements applicable to the Base Building when constructed and the Base
Building and the balance of the Real Property complies and will comply
throughout the term of this Lease with all Legal Requirements that must be
complied with in order for Tenant to use the Premises for the purposes permitted
hereunder in a normal and customary manner, except to the extent of any
non-compliance which is caused or triggered by any of the matters set forth in
clauses (i) through (iii) of Paragraph 8.b. above or which is Tenant's
responsibility pursuant to Paragraph 8.e. or any other provisions of this Lease;
provided, that, in no event shall the foregoing prohibit Landlord from including
in Operating Expenses any cost relating to such compliance that would otherwise
be included in Operating Expenses under Paragraph 7.a. above.

                In the event any of the representations or warranties in (i)
through (iii) above are determined to have been inaccurate when made or Landlord
violates any of such ongoing representations or warranties, promptly following
Landlord's actual knowledge of such inaccuracy or violation, Landlord shall
commence and pursue diligently until completion all work required to correct the
inaccuracy or violation and, so long as Landlord proceeds in such manner, Tenant
may not terminate this Lease as a result of such violation of the representation
or warranty; provided, however, that Landlord shall defend, indemnify, and hold
Tenant, its agents, and employees harmless from and against any and all Claims
to the extent arising from such inaccuracy or violation of the subject
representation or warranty.

                e. Tenant's Acknowledgment. Tenant acknowledges that, except for
the base Building systems required to be delivered by Landlord to Tenant in good
and working order and condition pursuant to Paragraph 4.a. above and the Ground
Floor Demising Work, Tenant shall be responsible for all work required to cause
the Premises to initially comply and continue to comply throughout the term
hereof with all applicable Legal Requirements, including, without limitation,
the Americans with Disabilities Act.

                f. Applicability of Paragraph. The provisions of this Paragraph
8 are for the benefit of Landlord, Tenant, the holder of any Superior Interest
(as defined in Paragraph 21 below), and the other Indemnitees only and are not
nor shall they be construed to be for the benefit of any other tenant or
occupant of the Building.

            9.  Alterations and Restoration.

                a. Tenant shall not make or permit to be made any alterations,
modifications, additions, decorations or improvements to the Premises, or any
other work whatsoever that would directly or indirectly involve the penetration
or removal (whether permanent or temporary) of, or require access through, in,
under, or above any floor, wall or ceiling, or surface or covering thereof in
the Premises (collectively, "Alterations"), except as expressly provided in this
Paragraph 9. If Tenant desires any Alteration, except for Cosmetic Alterations
as described in the immediately following grammatical paragraph, Tenant must
obtain Landlord's prior written approval of such Alteration, which approval
shall not be unreasonably withheld, conditioned or delayed.

            Notwithstanding the foregoing or anything to the contrary contained
elsewhere in this Paragraph 9, Tenant shall have the right, without Landlord's
consent, to make any Alteration to the Premises that meets all of the following
criteria (a "Cosmetic Alteration"): (a) the Alteration is decorative in nature
(such as paint, carpet or other wall or floor finishes, movable partitions or
other such work), (b) Tenant provides Landlord with five (5) days' advance
written notice of the commencement of such Alteration, (c) such Alteration does
not affect the Building's electrical, mechanical, life safety, plumbing,
security, or HVAC systems or any structural portion of the Building or any part
of the Building other than the Premises, (d) the work will not decrease the
value of the Premises, does not require a building permit or other governmental
permit, uses only new materials comparable in quality to those being replaced
and is performed in a workman like manner and in accordance with all applicable
Legal Requirements and (e) the work does not involve opening the ceiling of the
Premises. At the time Tenant notifies Landlord of any Cosmetic Alteration,
Tenant shall give Landlord a copy of Tenant's plans for the work. If the
Cosmetic Alteration is of such a nature that formal plans will not be prepared
for the work, Tenant shall provide Landlord with a reasonably specific
description of the work.

                                       13

<PAGE>

            All Alterations shall be made at Tenant's sole cost and expense
(including the expense of complying with all present and future Legal
Requirements, including those regarding asbestos, if applicable, and any other
work required to be performed in other areas within or outside the Premises by
reason of the Alterations). Tenant shall either (i) arrange for Landlord to
perform the work on terms and conditions acceptable to Landlord and Tenant, each
in its sole discretion or (ii) bid the project out to contractors approved by
Landlord in writing in advance (which approval shall not be unreasonably
withheld). Tenant shall provide Landlord with a copy of the information
submitted to bidders at such time as the bidders receive their copy. Regardless
of the contractors who perform the work pursuant to the above, Tenant shall pay
Landlord on demand prior to or during the course of such construction an amount
(the "Alteration Operations Fee") equal to three percent (3%) of the total cost
of the Alteration (and for purposes of calculating the Alteration Operations
Fee, such cost shall include architectural and engineering fees, but shall not
include permit fees) as compensation to Landlord for Landlord's internal review
of Tenant's Plans and general oversight of the construction (which oversight
shall be solely for the benefit of Landlord and shall in no event be a
substitute for Tenant's obligation to retain such project management or other
services as shall be necessary to ensure that the work is performed properly and
in accordance with the requirements of this Lease); provided, however, that the
Alteration Operations Fee shall be inapplicable to Cosmetic Alterations. Tenant
shall also reimburse Landlord for Landlord's actual expenses such as electrical
energy consumed in connection with the work, freight elevator operation,
additional cleaning expenses, additional security services, and any third party
costs (including costs of retaining third party architects or engineers)
reasonably incurred by Landlord as result of the work.

            All such work shall be performed diligently and in a first-class
workmanlike manner and in accordance with plans and specifications reasonably
approved by Landlord, and shall comply with all Legal Requirements and
Landlord's reasonable construction standards, procedures, conditions and
requirements for the Building as in effect from time to time (including
Landlord's reasonable requirements relating to insurance and contractor
qualifications). Any person, entity or contractor employed to perform work in
the Premises shall be subject to the provisions of the third grammatical
paragraph of Paragraph 8.a. above (without limitation of any other applicable
provisions of this Lease). Default by Tenant in the payment of any sums agreed
to be paid by Tenant for or in connection with an Alteration (regardless of
whether such agreement is pursuant to this Paragraph 9 or separate instrument)
shall entitle Landlord to all the same remedies as for non-payment of rent
hereunder. Any Alterations, including, without limitation, moveable partitions
that are affixed to the Premises (but excluding moveable, free standing
partitions) and all carpeting, shall at once become part of the Building and the
property of Landlord. In no event shall the foregoing be deemed to prevent
Tenant from removing any of Tenant's furniture, trade fixtures, equipment or
other personal property from the Premises during the Lease term or at the
expiration of the Lease term and Tenant agrees that Tenant shall repair, at
Tenant's sole cost, any damage to the Premises caused by such removal. Tenant
shall give Landlord not less than five (5) days prior written notice of the date
the construction of the Alteration is to commence. Landlord may post and record
an appropriate notice of non-responsibility with respect to any Alteration and
Tenant shall maintain any such notices posted by Landlord in or on the Premises.

                b. At Landlord's sole election any or all Alterations made for
or by Tenant shall be removed by Tenant from the Premises at the expiration or
sooner termination of this Lease and the Premises shall be restored by Tenant to
their condition prior to the making of the Alterations, ordinary wear and tear
excepted; provided, however, that if so requested by Tenant in writing (which
writing shall expressly refer to this Paragraph 9.b.) at the time Tenant
requests approval for an Alteration (or, with respect to Cosmetic Alterations,
at the time Tenant gives Landlord notice of such Cosmetic Alterations), Landlord
shall advise Tenant at the time of Landlord's approval of such Alteration (or
following Landlord's receipt of Tenant's notice to Landlord with respect to
Cosmetic Alterations) as to whether Landlord will waive the requirement that
such Alteration be removed by Tenant from the Premises. The removal of the
Alterations and the restoration of the Premises shall be performed by a general
contractor selected by Tenant and approved by Landlord, in which event Tenant
shall pay the general contractor's fees and costs in connection with such work.
Any separate work letter or other agreement which is hereafter entered into
between Landlord and Tenant pertaining to Alterations shall be deemed to
automatically incorporate the terms of this Lease without the necessity for
further reference thereto.

            10. Repair.

                a. Subject to Paragraph 10.b. below and Landlord's obligations
under Paragraphs 3, 4 and 8.b. above, by taking possession of the Premises,
Tenant agrees that the Premises are in good condition and repair. Tenant, at
Tenant's sole cost and expense, shall keep the Premises and every part thereof
in good condition and repair; provided that Tenant shall not be responsible for
repairs to the extent such repairs are (i) necessitated by the negligence or
willful misconduct of Landlord or Landlord's agents, employees or contractors,
or (ii) Landlord's obligation pursuant to Paragraph 10.b. below. Tenant waives
all rights to make repairs at the expense of Landlord as

                                       14

<PAGE>

provided by any Legal Requirement now or hereafter in effect. It is specifically
understood and agreed that, except as specifically set forth in this Lease,
Landlord has no obligation and has made no promises to alter, remodel, improve,
repair, decorate or paint the Premises or any part thereof, and that no
representations respecting the condition of the Premises or the Building have
been made by Landlord to Tenant. Tenant hereby waives the provisions of
California Civil Code Sections 1932(1), 1941 and 1942 and of any similar Legal
Requirement now or hereafter in effect.

                b. Repairs to the Premises necessitated because of fire,
earthquake, act of God or the elements shall be governed by Paragraph 26 below.
Landlord shall repair the Premises if they are damaged due to item (i) described
in Paragraph 10.a. above. Further, Landlord shall repair and maintain in good
condition and repair the Base Building (as defined in the last sentence of
Paragraph 8.b. above); provided, however, that to the extent repairs which
Landlord is required to make pursuant to the above are necessitated by the
negligence or willful misconduct of Tenant or Tenant's agents, employees or
contractors, or are due to Alterations performed by or for Tenant, then Tenant
shall reimburse Landlord for the cost of such repair within thirty (30) days
after Landlord's demand (accompanied by invoices or other reasonable
documentation supporting such costs) to the extent Landlord is not reimbursed
therefor by insurance. Landlord shall in no event be obligated to repair any
ordinary wear and tear to the Premises. Landlord shall repair and maintain the
Real Property in accordance with the foregoing provisions to the standards of
other first-class high-rise office buildings in downtown Oakland (including
buildings not owned or managed by Landlord or any affiliate thereof), and shall
perform all such repairs and maintenance with reasonable diligence (taking into
account the nature and urgency of the work) after receiving notice or otherwise
obtaining actual knowledge of the need for the same.

            11. Abandonment. Tenant shall not abandon the Premises or any part
thereof at any time during the term hereof. Tenant's mere vacating of the
Premises during the term hereof shall not constitute an abandonment under this
Lease nor an Event of Default so long as Tenant continues to pay Monthly Rent,
Additional Rent and all other sums due Landlord under this Lease and maintains
the insurance coverage required pursuant to Paragraph 15 of this Lease. Upon the
expiration or earlier termination of this Lease, or if Tenant abandons or
surrenders all or any part of the Premises or is dispossessed of the Premises by
process of law, or otherwise, any movable furniture, equipment, trade fixtures,
or other personal property belonging to Tenant and left on the Premises shall at
the option of Landlord be deemed to be abandoned and, whether or not the
property is deemed abandoned, Landlord shall have the right to remove such
property from the Premises and charge Tenant for the removal and any restoration
of the Premises as provided in Paragraph 9. Landlord may charge Tenant for the
storage of Tenant's property left on the Premises at such rates as Landlord may
from time to time reasonably determine, or, Landlord may, at its option, store
Tenant's property in a public warehouse at Tenant's expense. Notwithstanding the
foregoing, neither the provisions of this Paragraph 11 nor any other provision
of this Lease shall impose upon Landlord any obligation to care for or preserve
any of Tenant's property left upon the Premises, and Tenant hereby waives and
releases Landlord from any claim or liability in connection with the removal of
such property from the Premises and the storage thereof and specifically waives
the provisions of California Civil Code Section 1542 with respect to such
release. Landlord's action or inaction with regard to the provisions of this
Paragraph 11 shall not be construed as a waiver of Landlord's right to require
Tenant to remove its property, restore any damage to the Premises and the
Building caused by such removal, and make any restoration required pursuant to
Paragraph 9 above. For purposes of this Paragraph 11 and Paragraph 25 below,
"abandon" is used within the meaning of California Civil Code Section 1951.2.

            12. Liens. Tenant shall not permit any mechanic's, materialman's or
other liens arising out of work performed at the Premises by or on behalf of
Tenant to be filed against the fee of the Real Property nor against Tenant's
interest in the Premises. Landlord shall have the right to post and keep posted
on the Premises any notices which it deems necessary for protection from such
liens. If any such liens are filed and Tenant does not remove the same (by
payment, bonding or otherwise) within fifteen (15) days following the earlier of
Tenant's actual knowledge thereof or Landlord's written notice to Tenant
thereof, Landlord may, in addition to any other remedies available to Landlord,
upon five (5) further Business Days' written notice to Tenant, without waiving
its rights based on such breach by Tenant and without releasing Tenant from any
obligations hereunder, pay and satisfy the same and in such event the sums so
paid by Landlord shall be due and payable by Tenant immediately without notice
or demand, with interest from the date paid by Landlord through the date Tenant
pays Landlord, at the Interest Rate. Tenant agrees to indemnify, defend and hold
Landlord and the other Indemnitees (as defined in Paragraph 14.b. below)
harmless from and against any Claims (as defined in Paragraph 14.b. below) for
mechanics', materialmen's or other liens in connection with any Alterations,
repairs or any work performed, materials furnished or obligations incurred by or
for Tenant, except to the extent such claims relate to construction performed by
Landlord or its agents, unless Tenant was required to pay for all or part of
such work and failed to timely do so.

                                       15

<PAGE>

            13. Assignment and Subletting.

                a. Landlord's Consent. Landlord's and Tenant's agreement with
regard to Tenant's right to transfer all or part of its interest in the Premises
is as expressly set forth in this Paragraph 13. Tenant agrees that, except upon
Landlord's prior written consent or as otherwise expressly set forth herein,
which consent shall not (subject to Landlord's rights under Paragraph 13.d.
below) be unreasonably withheld, conditioned or delayed, neither this Lease nor
all or any part of the leasehold interest created hereby shall, directly or
indirectly, voluntarily or involuntarily, by operation of law or otherwise, be
assigned, mortgaged, pledged, encumbered or otherwise transferred by Tenant or
Tenant's legal representatives or successors in interest (collectively, an
"assignment") and neither the Premises nor any part thereof shall be sublet or
be used or occupied for any purpose by anyone other than Tenant (collectively, a
"sublease"). Any assignment or subletting without Landlord's prior written
consent shall, at Landlord's option, be void and shall constitute an Event of
Default entitling Landlord to terminate this Lease and to exercise all other
remedies available to Landlord under this Lease and at law.

            The parties hereto agree and acknowledge that, among other
circumstances for which Landlord may reasonably withhold its consent to an
assignment or sublease, it shall be reasonable for Landlord to withhold its
consent where: (i) the assignment or subletting would materially increase the
operating costs for the Building or the burden on the Building services, or
generate material additional foot traffic, elevator usage or security concerns
in the Building, or create a materially increased probability of the comfort
and/or safety of Landlord and other tenants in the Building being compromised or
reduced, (ii) the space will be used for a school or training facility, an
entertainment, sports or recreation facility, retail sales to the public (except
as to the Ground Floor Premises, for which retail use is permitted pursuant to
the limitations set forth in Paragraph 8.a. above), a personnel or employment
agency, an office or facility of any governmental or quasi-governmental agency
or authority, a place of public assembly (including without limitation a meeting
center, theater or public forum), any use by or affiliation with a foreign
government (including without limitation an embassy or consulate or similar
office), or a facility for the provision of social, welfare or clinical health
services or sleeping accommodations (whether temporary, daytime or overnight);
(iii) the proposed assignee or subtenant is a current tenant of the Building or
of any of the buildings located in Oakland, California and known as 1111
Broadway Street, 1300 Clay Street, 505 14th Street, 500 12th Street, 499 14th
Street ort 501 14th Street, and the landlord of the building in which that
current tenant is located has adequate available space in its building to meet
that current tenant's expansion requirement; (iv) Landlord reasonably
disapproves of the proposed assignee's or subtenant's reputation or
creditworthiness; (v) Landlord reasonably determines that the character of the
business that would be conducted by the proposed assignee or subtenant at the
Premises, or the manner of conducting such business, would be inconsistent with
the character of the Building as a first-class office building; (vi) the
proposed assignee or subtenant is an entity or related to an entity (a) with
whom Landlord or any affiliate of Landlord has been engaged in litigation, or
who has asserted a legal claim against Landlord or any affiliate of Landlord, or
against whom Landlord or any affiliate of Landlord has asserted a legal claim or
(b) to whom Landlord or any affiliate of Landlord has previously leased space
(or is an entity or related to an entity that has been a subtenant in a Building
owned by Landlord or an affiliate of Landlord) and such entity (or related
entity) has been in default of any of its obligations under the applicable lease
or sublease; (vii) the assignment or subletting may conflict with any exclusive
uses granted to other tenants of the Real Property, or with the terms of any
easement, covenant, condition or restriction, or other agreement affecting the
Real Property; (viii) the assignment or subletting would involve a change in use
from that expressly permitted under this Lease; or (ix) Landlord reasonably
determines that the proposed assignee may be unable to perform all of Tenant's
obligations under this Lease or, in the case of a proposed sublease for more
than 5,000 rentable square feet of space, the proposed subtenant may be unable
to perform all of its obligations under the proposed sublease. Landlord's
foregoing rights and options shall continue throughout the entire term of this
Lease.

            For purposes of this Paragraph 13, the following events shall be
deemed an assignment or sublease, as appropriate: (i) the issuance of equity
interests (whether stock, partnership interests or otherwise) in Tenant or any
subtenant or assignee, or any entity controlling any of them, to any person or
group of related persons, in a single transaction or a series of related or
unrelated transactions, such that, following such issuance, such person or group
shall have Control (as defined below) of Tenant or any subtenant or assignee;
(ii) a transfer of Control of Tenant or any subtenant or assignee, or any entity
controlling any of them, in a single transaction or a series of related or
unrelated transactions (including, without limitation, by consolidation, merger,
acquisition or reorganization), except that the transfer of outstanding capital
stock or other listed equity interests by persons or parties other than
"insiders" within the meaning of the Securities Exchange Act of 1934, as
amended, through the "over-the-counter" market or any recognized national or
international securities exchange, shall not be included in determining whether
Control has been transferred; (iii) a reduction of Tenant's assets to the point
that this Lease is substantially Tenant's only asset; (iv) a change or
conversion in the form of entity of Tenant, any subtenant or assignee, or any
entity controlling any of

                                       16

<PAGE>

them, which has the effect of limiting the liability of any of the partners,
members or other owners of such entity; or (v) the agreement by a third party to
assume, take over, or reimburse Tenant for, any or all of Tenant's obligations
under this Lease, in order to induce Tenant to lease space with such third
party. "Control" shall mean direct or indirect ownership of fifty percent (50%)
or more of all of the voting stock of a corporation or fifty percent (50%) or
more of the legal or equitable interest in any other business entity, or the
power to direct the operations of any entity (by equity ownership, contract or
otherwise). Paragraph 13.g. below contains provisions regarding an assignment or
sublease to an Affiliate of Tenant, which paragraph may apply to certain of the
transfer events that are deemed by this grammatical paragraph to constitute an
assignment or subletting of this Lease.

            If this Lease is assigned, whether or not in violation of the terms
of this Lease, Landlord may collect rent from the assignee. If the Premises or
any part thereof is sublet, Landlord may, upon an Event of Default by Tenant
hereunder, collect rent from the subtenant. In either event, Landlord may apply
the amount collected from the assignee or subtenant to Tenant's monetary
obligations hereunder.

            The consent by Landlord to an assignment or subletting hereunder
shall not relieve Tenant or any assignee or subtenant from the requirement of
obtaining Landlord's express prior written consent to any other or further
assignment or subletting. In no event shall any subtenant be permitted to assign
its sublease or to further sublet all or any portion of its subleased premises
without Landlord's prior written consent, which consent may be withheld by
Landlord in its sole and absolute discretion. Neither an assignment or
subletting nor the collection of rent by Landlord from any person other than
Tenant, nor the application of any such rent as provided in this Paragraph 13.a.
shall be deemed a waiver of any of the provisions of this Paragraph 13.a. or
release Tenant from its obligation to comply with the provisions of this Lease
and Tenant shall remain fully and primarily liable for all of Tenant's
obligations under this Lease. If Landlord approves of an assignment or
subletting hereunder and this Lease contains any renewal options, expansion
options, rights of first refusal, rights of first negotiation or any other
rights or options pertaining to additional space in the Building, such rights
and/or options shall not run to the subtenant or assignee (other than to an
assignee of this Lease that is an Affiliate of the original Tenant, as defined
in Paragraph 13.g. below), it being agreed by the parties hereto that any such
rights and options are personal to the Tenant originally named herein and
Affiliates thereof to whom Tenant has assigned the Lease, and may not otherwise
be transferred.

                b. Processing Expenses. Tenant shall pay to Landlord, as
Landlord's cost of processing each proposed assignment or subletting, an amount
equal to the sum of (i) Landlord's reasonable attorneys' and other professional
fees, plus (ii) the sum of One Thousand Dollars ($1,000.00) for the cost of
Landlord's administrative, accounting and clerical time (collectively,
"Processing Costs"), and the amount of all direct and indirect costs and
expenses incurred by Landlord arising from the assignee or sublessee taking
occupancy of the subject space (including, without limitation, costs of freight
elevator operation for moving of furnishings and trade fixtures, security
service, janitorial and cleaning service, and rubbish removal service).
Notwithstanding anything to the contrary herein, Landlord shall not be required
to process any request for Landlord's consent to an assignment or subletting
until Tenant has paid to Landlord the amount of Landlord's estimate of the
Processing Costs and all other direct and indirect costs and expenses of
Landlord and its agents arising from the assignee or subtenant taking occupancy,
provided that, within thirty (30) days after Landlord has completed processing
Tenant's request, Landlord shall reimburse Tenant any amount by which Tenant's
payment of Landlord's estimate exceeds Landlord's actual costs and expenses.

                c. Consideration to Landlord. In the event of any assignment or
sublease (excluding an assignment or sublease to an Affiliate) Landlord shall be
entitled to receive, as additional rent hereunder, fifty percent (50%) of any
consideration (including, without limitation, payment for leasehold
improvements) paid by the assignee or subtenant for the assignment or sublease
and, in the case of a sublease, fifty percent (50%) of the excess of the amount
of rent paid for the sublet space by the subtenant over the amount of Monthly
Rent under Paragraph 5 above and Additional Rent under Paragraph 7 above
attributable to the sublet space for the corresponding month; except that Tenant
may recapture, on an amortized basis over the term of the sublease or assignment
(i) any brokerage commissions paid by Tenant in connection with the subletting
or assignment (not to exceed commissions typically paid in the market at the
time of such subletting or assignment), (ii) Tenant's reasonable advertising and
marketing expenses paid in connection with the assignment or subletting, (iii)
any improvement allowance or construction costs incurred by Tenant, or other
out-of-pocket concessions made by Tenant, in connection with the assignment or
sublease and (iv) Tenant's reasonable attorneys fees incurred in connection with
the assignment or sublease, plus the fees paid by Tenant under Paragraph 13.b.
above (collectively the "Assignment or Subletting Costs"), provided that, as a
condition to Tenant recapturing the Assignment or Subletting Costs, Tenant shall
provide to Landlord, within ninety (90) days of Landlord's execution of
Landlord's consent to the assignment or subletting, a detailed accounting of the
Assignment or Subletting Costs

                                       17

<PAGE>

and supporting documents, such as receipts and construction invoices. To effect
the foregoing, Tenant shall deduct from the monthly amounts received by Tenant
from the subtenant or assignee as rent or consideration (i) the Monthly Rent and
Additional Rent payable by Tenant to Landlord for the subject space and (ii) the
incremental amount, on an amortized basis, of the Assignment or Subletting
Costs, and fifty percent (50%) of the then remaining sum shall be paid promptly
to Landlord. Upon Landlord's request, Tenant shall assign to Landlord all
amounts to be paid to Tenant by any such subtenant or assignee and that belong
to Landlord and shall direct such subtenant or assignee to pay the same directly
to Landlord. If there is more than one sublease under this Lease, the amounts
(if any) to be paid by Tenant to Landlord pursuant to this Paragraph 13.c. shall
be separately calculated for each sublease and amounts due Landlord with regard
to any one sublease may not be offset against rental and other consideration
pertaining to or due under any other sublease.

                d. Procedures. If Tenant desires to assign this Lease or any
interest therein or sublet all or part of the Premises, Tenant shall give
Landlord written notice thereof and the terms proposed (the "Sublease Notice"),
which Sublease Notice shall be accompanied by Tenant's proposed assignment or
sublease agreement (in which the proposed assignee or subtenant shall be named,
shall be executed by Tenant and the proposed assignee or subtenant, and which
agreement shall otherwise meet the requirements of Paragraph 13.e. below),
together with a current financial statement of such proposed assignee or
subtenant and any other information reasonably requested by Landlord. Landlord
shall have the prior right and option (to be exercised by written notice to
Tenant given within ten (10) Business Days after receipt of Tenant's notice) (i)
in the case of any proposed sublet, to sublet from Tenant any portion of the
Premises proposed by Tenant to be sublet, for the term for which such portion is
proposed to be sublet, but at the lesser of the proposed sublease rent or the
same rent (including Additional Rent as provided for in Paragraph 7 above) as
Tenant is required to pay to Landlord under this Lease for the same space,
computed on a pro rata square footage basis; (ii) in the event of an assignment
of the Lease, to terminate this Lease in its entirety, and in the event of a
sublease that will result in more than fifty percent (50%) of the Premises being
covered by one or more subleases or a sublease that will expire during the final
twelve (12) months of the Lease term (as the same may have been extended), to
terminate the Lease as it pertains to the portion of the Premises so proposed by
Tenant to be sublet or (iii) to approve or reasonably disapprove the proposed
assignment or sublease. If Landlord exercises its option in (i) above, then
Landlord may, at Landlord's sole cost, construct improvements in the subject
space and, so long as the improvements are suitable for general office purposes,
Landlord shall have no obligation to restore the subject space to its original
condition following the termination of the sublease (and in no event shall
Tenant have any removal or restoration obligation with respect to any
improvements constructed in the subject space by Landlord). If Landlord fails to
exercise any such option to sublet or to terminate, this shall not be construed
as or constitute a waiver of any of the provisions of Paragraphs 13.a., b., c.
or d. herein. If Landlord exercises any option to sublet or to terminate, any
costs of demising the portion of the Premises affected by such subleasing or
termination shall be borne by Landlord. In addition, Landlord shall have no
liability for any real estate brokerage commission(s) or with respect to any of
the costs and expenses that Tenant may have incurred in connection with its
proposed assignment or subletting (without limiting Tenant's right as set forth
above to recover the same as Assignment or Subletting Costs), and Tenant agrees
to indemnify, defend and hold Landlord and all other Indemnitees harmless from
and against any and all Claims (as defined in Paragraph 14.b. below), including,
without limitation, claims for commissions, arising from such proposed
assignment or subletting. Landlord's foregoing rights and options shall continue
throughout the entire term of this Lease.

                e. Documentation. No permitted assignment or subletting by
Tenant shall be effective until there has been delivered to Landlord a fully
executed counterpart of the assignment or sublease which expressly provides that
(i) the assignee or subtenant may not further assign this Lease or the sublease,
as applicable, or sublet the Premises or any portion thereof, without Landlord's
prior written consent (which, in the case of a further assignment or sublease
proposed by an assignee of this Lease, shall not be unreasonably withheld,
subject to Landlord's rights under the provisions of this Paragraph 13, and in
the case of a subtenant's assignment of its sublease or further subletting of
its subleased premises or any portion thereof, may be withheld in Landlord's
sole and absolute discretion), (ii) the assignee or subtenant will comply with
all of the provisions of this Lease (to the extent applicable, in the case of a
sublease), and Landlord may enforce the Lease (to the extent applicable, in the
case of a sublease) provisions directly against such assignee or subtenant,
(iii) in the case of an assignment, the assignee assumes all of Tenant's
obligations under this Lease arising on or after the date of the assignment, and
(iv) in the case of a sublease, the subtenant agrees to be and remain jointly
and severally liable with Tenant for the payment of rent pertaining to the
sublet space in the amount set forth in the sublease, and for the performance of
all of the terms and provisions of this Lease applicable to the sublet space. In
addition to the foregoing, no assignment or sublease by Tenant shall be
effective until there has been delivered to Landlord a fully executed
counterpart of Landlord's reasonable consent to assignment or consent to
sublease form. The failure or refusal of a subtenant or assignee to execute any
such instrument shall not release or discharge the subtenant or assignee from
its liability as set forth above. Notwithstanding the foregoing, however, no
subtenant or

                                       18

<PAGE>

assignee shall be permitted to occupy the Premises or any portion thereof unless
and until such subtenant or assignee provides Landlord with certificates
evidencing that such subtenant or assignee is carrying all insurance coverage
required of such subtenant or assignee under this Lease.

                f. No Merger. Without limiting any of the provisions of this
Paragraph 13, if Tenant has entered into any subleases of any portion of the
Premises, the voluntary or other surrender of this Lease by Tenant, or a mutual
cancellation by Landlord and Tenant, shall not work a merger, and shall, at the
option of Landlord, terminate all or any existing subleases or subtenancies or,
at the option of Landlord, operate as an assignment to Landlord of any or all
such subleases or subtenancies. If Landlord does elect that such surrender or
cancellation operate as an assignment of such subleases or subtenancies,
Landlord shall in no way be liable for any previous act or omission by Tenant
under the subleases or for the return of any deposit(s) under the subleases that
have not been actually delivered to Landlord, nor shall Landlord be bound by any
sublease modification(s) executed without Landlord's consent or for any advance
rental payment by the subtenant in excess of one month's rent.

                g. Affiliates. Notwithstanding anything to the contrary in
Paragraphs 13.a. and 13.d., but subject to Paragraphs 13.e. and 13.f., Tenant
may assign this Lease or sublet the Premises or any portion thereof, without
Landlord's consent, to any partnership, corporation or other entity which
controls, is controlled by, or is under common control with Tenant or Tenant's
parent (control being defined for such purposes as ownership of at least 50% of
the equity interests in, or the power to direct the management of, the relevant
entity) or to any partnership, corporation or other entity resulting from a
merger or consolidation with Tenant or Tenant's parent, or to any person or
entity which acquires substantially all the assets of Tenant as a going concern
(including, without limitation, a purchase of a controlling equity interest in
Tenant or Tenant's parent)(collectively, an "Affiliate"), provided that, (i)
Landlord receives at least ten (10) days prior written notice of an assignment
or subletting (provided, however, if the nature of the transaction that
constitutes an assignment to an Affiliate of Tenant is such that prior written
notice of the transaction cannot reasonably be provided to Landlord, then Tenant
shall provide Landlord with written notice of the assignment not later than five
(5) days after the effective date of the assignment), (ii) in the event of an
assignment of the Lease to an Affiliate, the Affiliate's net worth is not less
than the Tenant's net worth as of the date of the assignment and, in the event
of a sublease to an Affiliate, the Affiliate's net worth satisfies Landlord's
then financial criteria for new tenants leasing space within the Building that
is of the size of the space being sublet, provided that Tenant may not structure
a series of subleases to a particular Affiliate pursuant to which the Affiliate
subleases substantially all of the Premises in an effort to prevent the
transaction from being deemed an assignment of the Lease for purposes of this
item (ii), (iii) the transaction is for legitimate business purposes unrelated
to this Lease and the transaction is not a subterfuge by Tenant to avoid its
obligations under this Lease or the restrictions on assignment and subletting
contained herein, (iv) Landlord receives a fully executed copy of an assignment
or sublease agreement between Tenant and the Affiliate (unless the assignment
resulted from a purchase or transfer of equity interests so that the named
Tenant hereunder is not changed by such assignment), (v) in the event of an
assignment to an Affiliate, the Affiliate assumes in writing all of Tenant's
obligations under this Lease (unless the assignment resulted from a purchase or
transfer of equity interests so that the named Tenant hereunder is not changed
by such assignment), and (vi) in the event of a sublease to an Affiliate, Tenant
delivers to Landlord a fully executed counterpart of Landlord's reasonable
waiver and acknowledgment form for Affiliates containing waivers and
acknowledgements consistent with the waivers and acknowledgements given by
Tenant to Landlord under this Lease. The provisions of Paragraph 13.b. above
shall apply to a sublease or assignment to an Affiliate, except that the
Processing Costs shall be limited to Landlord's reasonable attorneys' and other
professional fees. The provisions of Paragraph 13.c. shall be inapplicable to an
assignment or sublease to an Affiliate of the Tenant originally named herein.

            If Tenant does not, within ten (10) business days after Landlord's
written request, provide Landlord with all instruments and information required
hereunder which are reasonably required to document that the proposed assignment
or sublease is a transfer to an Affiliate not requiring Landlord's consent
hereunder, then Landlord may, at Landlord's election made by written notice to
Tenant, treat the transfer or notice of the assignment or sublease as a notice
of intent to assign or sublet to a non-Affiliate, and all of Landlord's rights
hereunder with respect to a proposed assignment or sublease to a non-Affiliate
shall thereupon apply as if such request had been made on the date of Landlord's
election.

            14. Indemnification of Landlord.

                a. Except as otherwise expressly provided in this Lease
(including, without limitation, where Landlord shall expressly indemnify Tenant
under this Lease), Landlord and the holders of any Superior Interests (as
defined in Paragraph 21 below) shall not be liable to Tenant and Tenant hereby
waives all claims against such parties for any loss, injury or other damage to
person or property in or about the Premises or the Real Property from any cause
whatsoever,

                                       19

<PAGE>

including without limitation, water leakage of any character from the roof,
walls, basement, fire sprinklers, appliances, air conditioning, plumbing or
other portion of the Premises or the Real Property, or gas, fire, explosion,
falling plaster, steam, electricity, or any malfunction within the Premises or
the Real Property, or acts of other tenants of the Building; provided, however,
that the foregoing waiver shall be inapplicable to any loss, injury or damage to
the extent resulting from Landlord's gross negligence or willful misconduct.
Tenant acknowledges that from time to time throughout the term of this Lease,
construction work may be performed in and about the Building and the Real
Property by Landlord, contractors of Landlord, or other tenants or their
contractors, and that such construction work may result in noise and disruption
to Tenant's business. In addition to and without limiting the foregoing waiver
or any other provision of this Lease, Tenant agrees that Landlord shall not be
liable for, and Tenant expressly waives and releases Landlord and the other
Indemnitees (as defined in Paragraph 14.b. below) from any Claims (as defined in
Paragraph 14.b. below) arising or alleged to be arising as a result of any such
construction activity, except any claims to the extent caused by Landlord's
breach of any of its obligations under Paragraph 23 below (if any) applicable to
such construction activity, but subject to the last sentence of Paragraph 14.c.
and to Paragraph 17.f. below.

                b. Tenant shall hold Landlord and the holders of any Superior
Interest, and the constituent shareholders, partners or other owners thereof,
and all of their agents, contractors, servants, officers, directors, employees
and licensees (collectively with Landlord, the "Indemnitees") harmless from and
indemnify the Indemnitees against any and all claims, liabilities, damages,
costs and expenses, including reasonable attorneys' fees and costs incurred in
defending against the same (collectively, "Claims"), to the extent arising from
(a) the acts or omissions of Tenant or any other Tenant Parties (as defined in
Paragraph 8.c. above) in, on or about the Real Property, or (b) any construction
or other work undertaken by or on behalf of Tenant (other than work performed by
Landlord or it's agents) in, on or about the Premises, whether prior to or
during the term of this Lease, or (c) any breach or Event of Default under this
Lease by Tenant, or (d) any accident, injury or damage, howsoever and by
whomsoever caused, to any person or property, occurring in, on or about the
Premises; except to the extent such Claims are caused directly by the gross
negligence or willful misconduct of Landlord or its authorized representatives.
In case any action or proceeding be brought against any of the Indemnitees by
reason of any such Claim, Tenant, upon notice from Landlord, covenants to resist
and defend at Tenant's sole expense such action or proceeding by counsel
reasonably satisfactory to Landlord. The provisions of this Paragraph 14.b.
shall survive the expiration or earlier termination of this Lease with respect
to any injury, illness, death or damage occurring prior to such expiration or
termination.

                c. Subject to Paragraph 16 below, Landlord shall hold Tenant and
Tenant's shareholders, partners, members, officers, directors, agents and
employees (collectively with Tenant, "Tenant's Indemnitees") harmless from and
against any and all Claims incurred or arising from any injury, illness or death
to any person or damage to any property occurring in, on or about any part of
the Real Property to the extent such injury, illness, death, or damage shall be
caused by the negligent acts or omissions of Landlord, its agents, contractors
or employees, except to the extent caused by the negligence or willful
misconduct of Tenant's Indemnitees. The provisions of this Paragraph 14.c. shall
survive the termination of this Lease with respect to any injury, illness, death
or damage occurring prior to such termination. The indemnification obligations
of Landlord hereunder are not intended to and shall not relieve Landlord's
insurance carrier of its obligations to Landlord or to Tenant (if any). In case
any action or proceeding be brought against any Tenant's Indemnitees by reason
of any such Claim covered by the foregoing indemnity, Landlord, upon notice from
Tenant, covenants to resist and defend at Landlord's sole expense such action or
proceeding by counsel reasonably satisfactory to Tenant. Notwithstanding
anything to the contrary set forth in this Paragraph 14.c. or elsewhere in this
Lease (including, without limitation, in Paragraph 14.a.), except to the extent
arising out of the willful misconduct of Landlord or its officers, directors or
employees, in no event shall Landlord be liable for any consequential or remote
damages, lost profits or loss of business, or for loss or damage to artwork,
currency, jewelry, bullion, securities or other property in the Premises, not in
the nature of ordinary fixtures, furnishings, equipment and other property used
in general business office activities and functions.

                d. The provisions of this Paragraph 14 are subject to the
provisions of Paragraph 16 below.

            15. Insurance.

                a. Tenant's Insurance. Tenant shall, at Tenant's expense,
maintain during the term of this Lease (and, if Tenant occupies or conducts
activities in or about the Premises prior to or after the term hereof, then also
during such pre-term or post-term period): (i) commercial general liability
insurance including contractual liability coverage, with minimum coverages of
Three Million Dollars ($3,000,000.00) per occurrence combined single limit for
bodily injury and property damage, One Million Dollars ($1,000,000.00) for
products-completed operations coverage, One

                                       20

<PAGE>

Hundred Thousand Dollars ($100,000.00) fire legal liability, One Million Dollars
($1,000,000.00) for personal and advertising injury (which coverage shall not be
subject to the contractual liability exclusion), with a Five Million Dollars
($5,000,000.00) general aggregate limit, for injuries to, or illness or death
of, persons and damage to property occurring in or about the Premises or
otherwise resulting from Tenant's operations in the Building, (ii) property
insurance protecting Tenant against loss or damage by fire and such other risks
as are insurable under then-available standard forms of "special form"
(previously known as "all risk") insurance policies (excluding earthquake and
flood but including water damage), covering Tenant's personal property and trade
fixtures in or about the Premises or the Real Property, and any improvements
and/or Alterations in the Premises, for the full replacement value thereof
without deduction for depreciation; (iii) workers' compensation insurance in
statutory limits; (iv) at least three months' coverage for loss of business
income and continuing expenses, providing protection against any peril included
within the classification "special form" insurance, excluding earthquake and
flood but including water damage; and (v) if Tenant operates owned, leased or
non-owned vehicles on the Real Property, comprehensive automobile liability
insurance with a minimum coverage of One Million Dollars ($1,000,000.00) per
occurrence, combined single limit. The above described policies shall protect
Tenant, as named insured, and, except for workers' compensation insurance
described in clause (iii) above, shall protect Landlord and all the other
Indemnitees (except that any contractors and licensees that Landlord desires to
name as additional insureds shall be specified by name in writing to Tenant) and
any other parties designated by Landlord, as additional insureds; shall insure
Landlord's and such other parties' contingent liability with regard to acts or
omissions of Tenant; shall specifically include contractual liability with
regard to Tenant's obligations under this Lease (provided, however, that such
contractual liability coverage shall not limit or be deemed to satisfy Tenant's
indemnity obligations under this Lease); and, if subject to deductibles, shall
provide for deductible amounts not in excess of those approved in advance in
writing by Landlord in its sole discretion. Landlord reserves the right to
increase the foregoing amount of liability coverage from time to time as
Landlord reasonably determines is required to adequately protect Landlord and
the other parties designated by Landlord from the matters insured thereby;
provided, however, such increased amounts shall not materially exceed the
greater of (a) those amounts normally required for comparable first class office
buildings in downtown Oakland or (b) those amounts required to provide Landlord
with the same relative protection as the amounts set forth above as of the date
of this Lease. Notwithstanding the foregoing, Landlord makes no representation
that the limits of liability required hereunder from time to time shall be
adequate to protect Tenant. Landlord reserves the right to require that Tenant
cause any of its contractors, vendors, movers or other parties conducting
activities in or about or occupying the Premises to obtain and maintain
insurance as reasonably determined by Landlord and as to which Landlord and such
other parties reasonably designated by Landlord shall be additional insureds.

                b. Policy Form. Each insurance policy required pursuant to
Paragraph 15.a. above shall be issued by an insurance company licensed in the
State of California and with a general policyholders' rating of "A-" or better
and a financial size ranking of "Class VIII" or higher in the most recent
edition of Best's Insurance Guide. Each insurance policy, other than Tenant's
workers' compensation insurance, shall (i) provide that it may not be materially
changed, cancelled or allowed to lapse unless thirty (30) days' prior written
notice to Landlord and any other insureds designated by Landlord is first given
(provided, however, if Tenant's insurance company, as a general policy, will
only agree to a different standard with regard to notices required to be given
to an additional insured, then that standard of notice shall instead apply),
(ii) provide that no act or omission of Tenant shall affect or limit the
obligations of the insurer with respect to any other insured, (iii) include all
waiver of subrogation rights endorsements necessary to effect the provisions of
Paragraph 16 below, and (iv) provide that the policy and the coverage provided
shall be primary, that Landlord, although an additional insured, shall
nevertheless be entitled to recovery under such policy for any damage to
Landlord or the other Indemnitees by reason of acts or omissions of Tenant, and
that any coverage carried by Landlord shall be noncontributory with respect to
policies carried by Tenant. Each such insurance policy or a certificate thereof
shall be delivered to Landlord by Tenant on or before the effective date of such
policy and thereafter Tenant shall deliver to Landlord renewal policies or
certificates at least ten (10) days prior to the expiration dates of expiring
policies. If Tenant fails to procure such insurance or to deliver such policies
or certificates and such failure continues for ten (10) days after Tenant's
actual receipt of written notice thereof from Landlord, Landlord may, at its
option, procure the same for Tenant's account, and the cost thereof shall be
paid to Landlord by Tenant within thirty (30) days of Landlord's written demand.
Landlord may at any time, and from time to time, inspect and/or copy any and all
insurance policies required by this Lease.

                Nothing in this Paragraph 15 shall be construed as creating or
implying the existence of (i) any ownership by Tenant of any fixtures,
additions, Alterations, or improvements in or to the Premises or (ii) any right
on Tenant's part to make any addition, Alteration or improvement in or to the
Premises.

                c. Tenant's Blanket Insurance. Tenant may carry the insurance
required to be carried by it hereunder under a blanket policy of insurance that
covers other locations owned or

                                       21

<PAGE>

operated by the insuring party in addition to the Premises, provided that such
blanket policy shall be endorsed to specifically cover\ the Premises, and shall
provide the same amount and types of coverage for the Premises and Tenant's
activities in the Building that would be provided by a separate policy meeting
the requirements imposed upon Tenant under this Paragraph. Tenant shall provide
Landlord with any information reasonably requested by Landlord to determine
whether Tenant's blanket insurance policy complies with the foregoing
requirements.

                d. Landlord's Insurance. During the term hereof, Landlord shall
keep the Building insured through reputable insurance underwriters against
perils covered by then-available standard forms of "special form" (previously
known as "all risk") insurance policies, as such policies are in use from time
to time for comparable first-class high-rise office buildings in downtown
Oakland (excluding, at Landlord's option, perils such as earthquake, flood and
other standard exclusions), with a deductible provision deemed commercially
reasonable by Landlord, in an amount or amounts equal to not less than eighty
percent (80%) of the full replacement value of the Building (excluding the land
and the footings, foundations and installations below the basement level), or
such greater percentage as shall be required to preclude Landlord from being
deemed a coinsurer, without deduction for depreciation, including the costs of
demolition and debris removal, or such other fire and property damage insurance
as Landlord shall reasonably determine to give substantially equal or greater
protection.

            16. Mutual Waiver of Subrogation Rights. Each party hereto hereby
releases the other respective party and, in the case of Tenant as the releasing
party, the other Indemnitees, and the respective partners, shareholders, agents,
employees, officers, directors and authorized representatives of such released
party, from any claims such releasing party may have for damage to the Building,
the Premises or any of such releasing party's fixtures, personal property,
improvements and alterations in or about the Premises, the Building or the Real
Property that is caused by or results from risks insured against under any
"special form" insurance policies actually carried by such releasing party or
deemed to be carried by such releasing party; provided, however, that such
waiver shall be limited to the extent of the net insurance proceeds payable by
the relevant insurance company with respect to such loss or damage (or in the
case of deemed coverage, the net proceeds that would have been payable had the
deemed coverage been carried). For purposes of this Paragraph 16, Tenant shall
be deemed to be carrying any of the insurance policies required pursuant to
Paragraph 15.a. and b. above but not actually carried by Tenant, and Landlord
shall be deemed to carry the "special form" insurance policy required by
Paragraph 15.d. above if Landlord does not actually carry such policy and, for
purposes of applying this Paragraph 16 only, Landlord's deductible under its
special form property insurance policy shall not exceed $100,000.00. Each party
hereto shall cause each such special form insurance policy obtained by it to
provide that the insurance company waives all rights of recovery by way of
subrogation against the other respective party and the other released parties in
connection with any matter covered by such policy.

            17. Utilities.

                a. Basic Services. Landlord shall furnish the following
utilities and services ("Basic Services") for the Premises: (i) during the hours
of 8 A.M. to 6 P.M. ("Business Hours") Monday through Friday (except public
holidays) ("Business Days"), electricity for lighting and power for the Premises
(excluding the Ground Floor Premises, electricity for which is governed by
Paragraph 17.h. below) totaling .63 kilowatt-hours per rentable square foot of
the Premises per month, with any electrical usage above such amounts being
payable by Tenant as Excess Services in accordance with the provisions of
Paragraph 17.b. below, (ii) during Business Hours on Business Days, heat and air
conditioning required in Landlord's reasonable judgment for the comfortable use
and occupancy of the Premises (excluding the Ground Floor Premises, HVAC for
which is governed by Paragraph 17.j. below) for ordinary general office
purposes, (iii) unheated water for the restroom(s) in the public areas serving
the Premises and for any kitchens or break rooms in the Premises, (iv) elevator
service to the floor(s) of the Premises by non-attended automatic elevators for
general office pedestrian usage, (v) on Business Days, janitorial services in
accordance with the specifications set forth on attached Exhibit E, as the same
may be reasonably modified by Landlord from time to time, provided that such
modifications may not reduce the quality of the janitorial services below the
quality of janitorial services generally provided at other first class office
buildings in downtown Oakland, and provided further, that janitorial services
shall not be provided by Landlord to the Ground Floor Premises and Tenant shall
provide such janitorial services pursuant to Paragraph 17.i. below and (vi)
freight elevator service, subject to Landlord's reasonable procedures regarding
scheduling and fees for the use thereof. Notwithstanding the foregoing, however,
Tenant may use water, heat, air conditioning, electric current, elevator and
janitorial service in excess of that provided in Basic Services ("Excess
Services," which shall include, without limitation, electricity in excess of
that described in clause (i) above or electricity consumed during non-Business
Hours; and water used for any purpose other than ordinary drinking, lavatory and
kitchen purposes), provided that the Excess Services desired by Tenant are
reasonably available to Landlord and to the Premises (it being understood that
in no event shall Landlord be obligated to make available to the Premises more
than

                                       22

<PAGE>

the pro rata share of the capacity of any Excess Service available to the
Building or the applicable floor of the Building, as the case may be), and
provided further that Tenant complies with the procedures established by
Landlord from time to time for requesting and paying for such Excess Services
and with all other provisions of this Paragraph 17. Landlord reserves the right
to install in the Premises or the Real Property electric current and/or water
meters (including, without limitation, any additional wiring, conduit or panel
required therefor) to measure the electric current or water consumed by Tenant
or to cause the usage to be measured by other reasonable methods (e.g., by
temporary "check" meters or by survey).

                b. Payment for Utilities and Services. The cost of Basic
Services shall be included in Operating Expenses. In addition, Tenant shall pay
to Landlord upon demand (i) the actual cost to Landlord of providing any Excess
Services used by Tenant, (ii) the cost of installing, operating, maintaining or
repairing any meter or other device used to measure Tenant's consumption of
utilities (but Tenant shall only be required to pay for such costs thereof if
the meter was installed and/or utilized by Landlord as a result of Landlord's
reasonable determination that Tenant was utilizing Excess Services), (iii) the
cost of installing, operating, maintaining or repairing any Temperature Balance
Equipment (as defined in Paragraph 17.d. below) for the Premises and/or any
equipment required in connection with any Excess Services requested by Tenant,
and (iv) any cost otherwise incurred by Landlord in keeping account of or
determining any Excess Services used by Tenant. Landlord's failure to bill
Tenant for any of the foregoing shall not waive Landlord's right to bill Tenant
for the same at a later time, provided that such bill is delivered to Tenant no
later than one hundred eighty (180) days after the end of the calendar year in
which such utilities or services were provided.

                c. Utility Connections. Tenant shall not connect or use any
apparatus or device in the Premises which would exceed the capacity of the
existing panel or transformer serving the Premises. Notwithstanding the
foregoing, Tenant may install 208v, 208 3PH, 240V and 480 3PH circuits within
the Premises and utilize electric current from such circuits, provided that
Tenant performs any Alterations required to accommodate such extra voltage,
which Alterations shall be performed in accordance with Paragraph 9 above.
Tenant shall not connect with electric current (except through existing outlets
in the Premises or such additional outlets as may be installed in the Premises
as part of initial improvements or Alterations approved by Landlord), or water
pipes, any apparatus or device for the purpose of using electrical current or
water.

            Landlord will not permit additional coring or channeling of the
floor of the Premises in order to install new electric outlets in the Premises
unless Landlord is satisfied, on the basis of such information to be supplied by
Tenant at Tenant's expense, that coring and/or channeling of the floor in order
to install such additional outlets will not weaken the structure of the floor.

                d. Temperature Balance. If the temperature otherwise maintained
in any portion of the Premises by the heating, air conditioning or ventilation
system is affected as a result of (i) the type or quantity of any lights,
machines or equipment (including without limitation typical office equipment)
used by Tenant in the Premises, (ii) the occupancy of such portion of the
Premises by more than one person per one hundred fifty (150) square feet of
rentable area therein, (iii) an electrical load for lighting or power in excess
of the limits specified in Paragraph 17.c. above, or (iv) any rearrangement of
partitioning or other improvements, then at Tenant's sole cost, Landlord may
install any equipment, or modify any existing equipment (including the standard
air conditioning equipment) Landlord deems necessary to restore the temperature
balance (such new equipment or modifications to existing equipment termed herein
"Temperature Balance Equipment"). Tenant agrees to keep closed, when necessary,
draperies and/or window treatments which, because of the sun's position, must be
closed to provide for the efficient operation of the air conditioning system,
and Tenant agrees to cooperate with Landlord and to abide by the regulations and
requirements which Landlord may prescribe for the proper functioning and
protection of the heating, ventilating and air conditioning system. Landlord
makes no representation to Tenant regarding the adequacy or fitness of the
heating, air conditioning or ventilation equipment in the Building to maintain
temperatures that may be required for, or because of, any computer or
communications rooms, machine rooms, conference rooms or other areas of high
concentration of personnel or electrical usage, or any other uses other than or
in excess of the fractional horsepower normally required for office equipment,
and Landlord shall have no liability for loss or damage suffered by Tenant or
others in connection therewith.

                e. Interruption of Services. Landlord's obligation to provide
utilities and services for the Premises are subject to the Rules and Regulations
of the Building, applicable Legal Requirements (including the rules or actions
of the public utility company furnishing the utility or service), and shutdowns
for maintenance and repairs, for security purposes, or due to strikes, lockouts,
labor disputes, fire or other casualty, acts of God, or other causes beyond the
control of Landlord. Except as set forth herein, in the event of an interruption
in, or failure or inability to provide any service or utility for the Premises
for any reason (or an interruption in, or failure or

                                       23

<PAGE>

inability to obtain, any of the services covered by Paragraph 17.h. or i.
below), such interruption, failure or inability shall not constitute an eviction
of Tenant, constructive or otherwise, or impose upon Landlord any liability
whatsoever, including, but not limited to, liability for consequential damages
or loss of business by Tenant, or entitle Tenant to any abatement or offset of
Monthly Rent, Additional Rent or any other amounts due from Tenant under this
Lease. Tenant hereby waives the provisions of California Civil Code Section
1932(1) or any other applicable existing or future Legal Requirement permitting
the termination of this Lease due to such interruption, failure or inability.
Notwithstanding the foregoing, but not in limitation thereof, Landlord shall use
commercially reasonable efforts to restore as soon as reasonably possible any
services required to be provided by Landlord under Paragraph 17.a. above, or
Paragraph 17.h. below (if applicable), that have failed or been interrupted.
Further, if any interruption in, or failure or inability to provide any of the
services or utilities described in Paragraph 17.a. or 17.h. (if applicable) is
within Landlord's reasonable control and continues for seven (7) or more
consecutive Business Days after Tenant's written notice thereof to Landlord, and
Tenant is unable to conduct and does not conduct any business in a material
portion of the Premises as a result thereof, and as a further result thereof
Tenant is unable to conduct its business in the Premises in substantially the
manner as it was conducted in the Premises prior to such interruptions, then
Tenant shall be entitled to an abatement of Monthly Rent under Paragraph 5
hereof and Additional Rent under Paragraph 7 hereof, which abatement shall
commence as of the first day after the expiration of such seven (7) Business Day
period and terminate upon the cessation of such interruption, failure or
inability, and which abatement shall be based on the portion of the Premises
rendered unusable for Tenant's business by such interruption, failure or
inability. Further, if any such interruption is within Landlord's reasonable
control to correct and continues for sixty (60) or more consecutive days, and
Tenant is unable to conduct and does not conduct any business in a material
portion of the Premises as a result thereof, and as a further result thereof
Tenant is unable to conduct its business in the Premises in substantially the
manner as it was conducted in the Premises prior to such interruptions then,
Tenant may, upon written notice provided to Landlord before the interruption is
corrected, terminate this Lease as of the date specified in such notice, which
date shall be not more than thirty (30) days after the date of such notice. The
abatement and termination rights set forth above shall be inapplicable to any
interruption, failure or inability described in this Paragraph 17.e. that is
caused by (x) the malfunction or disrepair of any systems, materials or items
installed by Tenant as a part of the Initial Alterations or subsequent
Alterations, (y) damage from fire or other casualty (it being acknowledged that
such situation shall be governed by Paragraph 26 below), or (z) the negligence
or willful misconduct of Tenant or its agents, employees or contractors, except
that the abatement provided for above will be available in such instance if
Tenant reimburses Landlord for the deductible required under Landlord's property
damage/rental loss insurance.

                f. Governmental Controls. In the event any governmental
authority having jurisdiction over the Real Property or the Building promulgates
or revises any Legal Requirement or building, fire or other code or imposes
mandatory or voluntary controls or guidelines on Landlord or the Real Property
or the Building relating to the use or conservation of energy or utilities or
the reduction of automobile or other emissions (collectively, "Controls") or in
the event Landlord is required or elects to make alterations to the Real
Property or the Building in order to comply with such mandatory or voluntary
Controls, Landlord may, in its sole discretion, comply with such Controls or
make such alterations to the Real Property or the Building related thereto. Such
compliance and the making of such alterations shall not constitute an eviction
of Tenant, constructive or otherwise, or impose upon Landlord any liability
whatsoever, including, but not limited to, liability for consequential damages
or loss of business by Tenant, except to the extent Landlord breaches any of its
obligations under Paragraph 23 below (if any) applicable to such alterations or
fails to use reasonable efforts to minimize any disruptions to Tenant's business
in the Premises, subject, however, to the following sentence and to the last
sentence of Paragraph 14.c. above. Without limitation of the foregoing, except
to the extent that it would, in Landlord's reasonable judgment, jeopardize
Landlord's ability to timely comply with such Controls, and except further to
the extent an emergency requires otherwise (as reasonably determined by
Landlord), Landlord shall perform any extraordinarily noisy or disruptive work
after Business Hours or on weekends.

                g. Security. Landlord shall supply security guard services to
the Building limited to after Business Hours Building lobby check-in and
check-out procedures in accordance with the standards of other first-class
high-rise office buildings in downtown Oakland; provided, however, that neither
Landlord nor any other Indemnitees shall be liable to Tenant, Tenant's
employees, invitees or any other person or entity for (and Tenant waives all
claims against them arising by reason of) direct or consequential damages,
including, without limitation, damage or injury to person or property or loss of
life, resulting from the presence, admission to or exclusion from the Building
or the Real Property of any person, and Tenant acknowledges that Landlord's
provision of security guards or other security services for the Building or the
Real Property shall not be construed as Landlord's or any Indemnitee's
acceptance of any responsibility or liability for the security of persons or
property in, on, or about the Premises, the Building or the Real Property.

                                       24

<PAGE>

                h. Electricity for Ground Floor Premises. Subject to the
immediately following sentence, Landlord will not provide electricity to the
Ground Floor Premises and Tenant shall obtain the same directly from, and pay
for the cost of the same directly to, the utility company that provides
electricity to the Building. Notwithstanding the foregoing, rather than obtain
electricity directly from the utility company, Tenant may, at Tenant's option,
obtain electricity for the Ground Floor Premises, in an amount not to exceed 600
Amps, from the electricity supply within the Building, with Tenant paying for
the cost of the electricity consumed at the Ground Floor Premises directly to
the utility company; provided, however, that this option shall only be available
to Tenant if Tenant makes such election within ninety (90) days following the
date of this Lease and thereafter commences the work required to make such
connection to the Building's electricity supply within six (6) months following
the date of this Lease. As provided in Paragraph 4.a. above, the Initial
Alterations being constructed by Tenant's Contractor in the Ground Floor
Premises shall include the installation of the equipment and installations
required to bring electricity to the Ground Floor Premises from outside of the
Building or to connect the Ground Floor Premises to the Building's electricity
supply (whichever is applicable), including, without limitation, the
installation of a meter to measure electricity consumed in the Ground Floor
Premises so that Tenant can be billed directly by the utility company for the
electricity consumed in the Ground Floor Premises. The cost of the purchase and
installation of the electrical equipment and the meter shall be borne by Tenant,
provided that the Alterations Allowance may be applied to such costs. Throughout
out the Lease term, Tenant shall maintain the electrical equipment and the
electricity meter in good condition and repair at Tenant's sole cost and
expense. At the expiration or earlier termination of this Lease, the electrical
equipment and meter shall remain in the Premises as the property of Landlord.

                i. HVAC for Ground Floor Premises; Tenant's Cooling Tower.

                    (a) Tenant's HVAC System; Connection to Building's Condenser
Water Supply. The Ground Floor Premises will not be connected to the Building's
heating, ventilating and air conditioning system and the Initial Alterations
shall include the installation of any such systems required by Tenant for the
Ground Floor Premises. The cost of the purchase and installation of such systems
shall be borne by Tenant, provided that the Alterations Allowance may be applied
to such costs. Throughout out the Lease term, Tenant shall maintain such systems
in good condition and repair at Tenant's sole cost and expense. The provisions
of Paragraph 9.b. above shall govern as to whether such systems shall be removed
from the Ground Floor Premises at the expiration or earlier termination of this
Lease. In no event shall the foregoing be deemed to prohibit Tenant from
removing from the Ground Floor Premises during the Lease term or at the
expiration or earlier termination of the Lease those supplemental HVAC systems
and equipment that are a part of, and directly cool, Tenant's computer equipment
(rather than supplemental HVAC systems that cool the room within which the
equipment is located) which supplemental HVAC systems and equipment shall remain
Tenant's personal property and shall be removed by Tenant at the expiration or
earlier termination of this Lease in accordance with Paragraph 20.a. below.

                Notwithstanding the above, Landlord shall allow Tenant to
connect Tenant's air conditioning system for the Ground Floor Premises into the
Building's condenser water supply; provided, however, in no event may such
equipment exceed one hundred thirty (130) tons in size. Tenant shall, at
Tenant's sole expense, cause such connections to be performed by contractors
reasonably approved in advance in writing by Landlord and in accordance with
Landlord's reasonable requirements for such connections. Landlord shall not
charge Tenant for the hook-up of Tenant's equipment to the Building's condenser
water supply. However, commencing on the date Tenant's connection to the
Building's condenser water supply is completed and continuing until such time as
the connection is disconnected, Tenant shall pay an annual fee of Four Hundred
Dollars ($400.00) per ton of condenser water per annum (which amount per ton may
be increased by Landlord from time to time to reflect Landlord's then annual
cost, without mark-up, per ton of providing the condenser water), based on the
size of Tenant's air conditioning equipment, rather than Tenant's actual
consumption of the condenser water for such year. Notwithstanding the foregoing,
Landlord may temporarily shut down the Building's condenser water loop in an
emergency or for routine maintenance or repair and, during such period that the
condenser water is unavailable to Tenant, Tenant shall be responsible for
otherwise providing cooling to the Ground Floor Premises at Tenant's sole cost
and Landlord shall have no responsibility therefor, nor shall Landlord be liable
to Tenant for any costs or damages incurred by Tenant as a result of the
temporary unavailability of the condenser water. Except in the event of an
emergency, Landlord shall use reasonable efforts to provide Tenant with advance
written notification of the period that the condenser water will be unavailable
to Tenant. If the condenser water required to be provided by Landlord to Tenant
hereunder is unavailable for more than five (5) consecutive Business Days, then
from and after the sixth (6th) consecutive Business Day of such unavailability,
Tenant shall receive an abatement of the portion of the annual fee for condenser
water provided for above that is attributable to the period of unavailability.

                    (b) Tenant's Right to Install Dedicated Cooling Tower.

                    i. Tenant's Cooling Tower and Cooling Tower Site. As an
alternative to connecting Tenant's air conditioning for the Ground Floor
Premises to the Building's condenser water supply, Tenant shall, at Tenant's
option, have a license to install and operate a 130 ton closed circuit cooling
tower ("Tenant's Cooling Tower") on the roof of the 21st floor mechanical
penthouse of the Building to provide the condenser water for Tenant's air
conditioning system for the Ground Floor Premises; provided, however, that this
option shall only be available to Tenant if Tenant makes such election, and
commences the work required to install Tenant's Cooling Tower, within ninety
(90) days following the date of this Lease. The exact location for the
installation of Tenant's Cooling Tower on such roof (the "Cooling Tower Site")
shall be designated by Landlord. Tenant shall also have a license to use a
vertical shaft of the Building, as designated by Landlord, for the installation
of two (2) copper pipes not to exceed six (6) inches each in diameter to bring
the condenser water from Tenant's Cooling Tower to Tenant's air conditioning
equipment serving the Ground Floor Premises and back again. The Cooling Tower
and all equipment, connections, pipes and lines related thereto, and any
replacement, alteration, addition or installation thereof approved by Landlord
pursuant to this Paragraph 17.i.(b) are collectively referred to herein as the
"Cooling Tower Equipment". The Cooling Tower Site and the areas of the Building
in which the Equipment shall be located are collectively referred to herein as
the "Cooling Tower Ancillary Sites".

                    ii. Lease Provisions Applicable. The provisions of the other
paragraphs of this Lease shall apply to the Cooling Tower Ancillary Sites and
the licenses granted under this Paragraph 17.i.(b), except to the extent
inconsistent with the provisions of this Paragraph 17.i.(b). Without limiting
the generality of the foregoing, the provisions of Paragraph 14 (Indemnification
of Landlord), Paragraph 15 (Insurance) and Paragraph 20 (Surrender; Holding
Over), shall apply in full to Tenant's License of the Cooling Tower Ancillary
Sites and Tenant's installation, operation and maintenance of the Cooling Tower
Equipment. If Tenant fails to perform any of its obligations under this
Paragraph 17.i.(b) and such failure continues for ten (10) days after written
notice thereof from Landlord (or if the failure cannot by its nature be cured
within the 10-day period, if Tenant fails to commence to cure such failure
within the 10-day period and thereafter diligently prosecute such cure to
completion), such failure shall constitute an Event of Default entitling
Landlord to the remedies under Paragraph 25.b. of the Lease and, in addition to
the other remedies set forth in Paragraph 25.b. for an Event of Default, upon
such Event of Default, Landlord may terminate the licenses granted under this
Paragraph 17.i.(b) by written notice to Tenant. Notwithstanding anything to the
contrary herein, Landlord shall not be obligated to provide any water, gas,
electricity or other utilities to the Cooling Tower Ancillary Sites. Without
limiting Paragraph 14.b. of the Lease, Tenant expressly agrees to indemnify,
defend and save harmless Landlord and the other Indemnitees from and against all
Claims arising (or claimed to have arisen) from the installation, maintenance
and operation of the Equipment or the Cooling Tower Equipment, except to the
extent arising from the gross negligence or willful misconduct of Landlord or
any other Indemnitee. In addition to the provisions of Paragraph 28 of this
Lease, Landlord shall in no event be liable for any loss or damage to the
Cooling Tower Equipment, or for any losses or damages arising out of or in
connection with any loss or damage to the Cooling Tower Equipment or failure of
the Cooling Tower Equipment to operate when needed (except to the extent caused
by the gross negligence or willful misconduct of Landlord or its employees' or
agents') and Tenant shall install and maintain the Cooling Tower Equipment in
such manner as to protect it against damage and disruption.

                    iii. Installation Plans; Approval. Tenant shall submit to
Landlord for Landlord's prior approval detailed plans and specifications (in
form acceptable to Landlord) for the Cooling Tower Equipment to be installed by
Tenant on the Cooling Tower Ancillary Sites. Further, Tenant shall submit to
Landlord detailed plans and specifications for any subsequent modification or
replacement of the Cooling Tower Equipment. Tenant shall not commence any such
installation, modification or replacement until such plans and specifications
have been approved in writing by Landlord and Tenant shall have submitted such
evidence as Landlord shall reasonably require evidencing that Tenant has
obtained all necessary governmental approvals and permits for installation and
operation of the Cooling Tower Equipment. Further, no work shall commence until
Landlord has received from Tenant the insurance required by Landlord, in
accordance with Landlord's construction procedures for the Building, for
Tenant's contractor(s) performing the work. Landlord shall have no
responsibility for, and Tenant holds Landlord harmless from, any failure of
Tenant's Cooling Tower Equipment to function properly notwithstanding the fact
that Landlord may have approved plans and specifications therefor. Tenant shall
keep the Cooling Tower Ancillary Sites and the Building free from any liens
arising out of any work performed, materials furnished or obligations incurred
with respect to the Cooling Tower Equipment. Tenant shall install, maintain and
operate the Cooling Tower Equipment in a safe manner that shall not overburden
or otherwise adversely affect any walls, floors, ceilings or any other
structural or nonstructural elements in the Building or the electrical system
therein. Tenant shall give Landlord not less than ten (10) days prior written
notice of the commencement of any construction or installation under this
Paragraph 17.i.(b). If required by Landlord, Tenant shall obtain opinions from
engineers reasonably acceptable to Landlord (or at Landlord's sole discretion,
shall reimburse Landlord's out of pocket and reasonable costs for

                                       26

<PAGE>

obtaining such opinions directly) stating that the Equipment and work to be done
with respect thereto will not adversely affect other lines or equipment at the
Building, the Building systems and equipment (including without limitation,
electrical, heating, ventilating, air-conditioning, plumbing, alarm and fire
protection), or the Building structure. At all times during the term of this
Lease, Tenant shall maintain with Landlord a current and complete record of all
of Tenant's Equipment in the Building.

            Landlord's approval of, or requirements concerning, the Cooling
Tower Equipment or any plans and specifications, contractors and subcontractors
for the design or installation thereof, shall not be deemed a waiver of any of
the provisions of this Lease, nor a warranty as to the adequacy of the design,
workmanship or quality of materials or installation or compliance with
applicable Legal Requirements, and Landlord shall have no responsibility or
liability for the same. Landlord shall have no responsibility for any
deficiencies in drawings submitted by Tenant for approval by Landlord or any
failure of such drawings to reflect actual conditions (concealed or apparent) at
the Building, including without limitation any failure of the drawings to
reflect existing equipment, walls or other facilities. In the case any such
drawings are deficient, Landlord may require that Tenant stop the installation
work and revise the drawings. Any matters not specifically reflected in the
drawings (including for example, but not limited to, the height of any proposed
wall penetration or the height at which the Lines will be run) shall be subject
to Landlord's prior written approval, which may be withheld in Landlord's
reasonable discretion.

                    iv. Impositions; Charges. Tenant shall be responsible for
and promptly pay all additional real and personal property taxes, assessments,
charges, fees or other governmental impositions levied or assessed on the
Building, the Real Property, Landlord or Tenant due to the Cooling Tower
Equipment or the construction, operation or removal thereof. In addition, Tenant
shall pay to Landlord within fifteen (15) days following written demand, an
amount equal to the reasonable and actual out-of-pocket expenses incurred by
Landlord in connection with the installation of the Cooling Tower Equipment (or
any subsequent modification to, or replacement or removal of, the Cooling Tower
Equipment), including, without limitation, any costs incurred by Landlord in
retaining third party engineers or consultants for the review of the plans and
specifications for the installations and/or for monitoring the installation,
modifications or removal. Landlord's review of the plans and monitoring of the
work shall be solely for the benefit of Landlord and shall in no event be a
substitute for Tenant's obligation to retain such project management or other
services as shall be necessary to ensure that the work is performed properly and
in accordance with the requirements of this Paragraph 17.i.(b).

                    v. Use; Compliance With Law. Tenant agrees that Tenant shall
not sell the services of the Cooling Tower Equipment, or otherwise use the
Cooling Tower Equipment to provide condenser water to any party other than
Tenant or to any other location other than the Ground Floor Premises. Landlord
makes no representation that Tenant's contemplated use of the Equipment or the
Cooling Tower Ancillary Sites will comply with applicable Legal Requirements.
Tenant, at Tenant's sole expense, shall comply with all Legal Requirements
regarding the installation, construction, operation and maintenance of the
Cooling Tower Equipment, and shall be solely responsible for obtaining and shall
obtain and keep in force all permits, licenses and approvals necessary for
operation of the Cooling Tower Equipment (provided that in doing so Tenant shall
not adversely affect Landlord or impair in any way Landlord's current and
permitted use of the Building). If at any time during the term of the License
such permits or approvals shall expire and are not renewed within thirty (30)
days after the expiration thereof, or if applicable Legal Requirements shall
otherwise not permit the Cooling Tower Equipment to remain or be operated on the
Cooling Tower Ancillary Sites, Tenant shall promptly remove the Cooling Tower
Equipment in accordance with the provisions set forth below applicable to
Tenant's removal of the Cooling Tower Equipment upon the expiration or earlier
termination of the License. Tenant shall not use any portion of the Cooling
Tower Ancillary Sites for the storage, generation or handling of Hazardous
Materials.

                    vi. Removal of Cooling Tower Equipment. The Cooling Tower
Equipment shall be and remain Tenant's property throughout the term of the
License granted hereunder. If Tenant is required to remove the Cooling Tower
Equipment by any governmental agency having jurisdiction over the Cooling Tower
Equipment, Tenant shall immediately, at its sole expense, remove all of the
Cooling Tower Equipment from the Cooling Tower Ancillary Sites and restore any
damage caused by the installation or removal thereof. Upon the expiration or
earlier termination of the Lease, the Cooling Tower Equipment shall become the
property of Landlord and shall remain at the Building; provided, however, that,
at Landlord's sole option, Landlord may elect to require Tenant to remove the
Cooling Tower Equipment from the Cooling Tower Ancillary Sites at the expiration
or earlier termination of this Lease, provided that Landlord provides Tenant
with written notice of such election not later than thirty (30) days following
the expiration or earlier termination of this Lease. If Landlord does so elect
to require Tenant to remove the Cooling Tower Equipment from the Building, then
Tenant, at Tenant's sole expense, shall remove all of the Cooling Tower
Equipment from the Cooling Tower Ancillary Sites and restore any damage caused
by the installation or removal thereof

<PAGE>

                    vii. Access to Cooling Tower Ancillary Sites. Subject to the
notice requirements hereinafter set forth, Tenant shall have the right, at
Tenant's sole cost and expense, to enter upon the Cooling Tower Ancillary Sites
to construct, install, operate and maintain the Cooling Tower Equipment on the
Cooling Tower Ancillary Sites until the licenses hereunder terminate. Tenant may
access the Cooling Tower Ancillary Sites and perform construction work therein
in accordance with the plans and specifications approved by Landlord pursuant to
Paragraph 17.i.(b).iii. above. Tenant may have access to the Cooling Tower
Ancillary Sites for normal repairs during the business hours of the Building
upon not less than twenty-four (24) hours' prior telephone notice to the
Building manager (or such other representative of Landlord as may be designated
by Landlord from time to time by notice to Tenant) and otherwise in accordance
with the rules and procedures (including scheduling requirements) of the
Building as in effect from time to time for such access and work. Tenant may
access the Cooling Tower Ancillary Sites for emergency repairs in accordance
with such rules and procedures of the Building as in effect from time to time
for such emergency access and work. A representative of Landlord shall be
entitled to be present any time Tenant wishes to access the Cooling Tower
Ancillary Sites (including emergency access), and Tenant shall not access the
Cooling Tower Ancillary Sites at any time without such representative unless
Landlord shall have expressly waived such requirement in writing. Landlord may
allow access to the Cooling Tower Ancillary Sites to any persons who show
evidence which, in the sole good faith judgment and discretion of Landlord,
appears to constitute authorization by Tenant or by any other tenant granted
rights by Landlord to install, operate and/or maintain facilities or equipment
of any kind in such areas of the Building, or by any representative or agent of
Landlord for such access. Tenant shall reimburse Landlord for Landlord's costs
of monitoring and/or supervising Tenant's activities in connection with the
License granted hereunder (including, without limitation, Landlord's
engineering, security or other personnel costs), and such costs shall be payable
by Tenant within fifteen (15) days of billing.

                    vii. Landlord's Liability. Landlord shall have no obligation
to design, install, construct, use, operate, maintain, repair, replace or remove
Tenant's Cooling Tower Equipment nor any other responsibility or liability in
connection therewith.

                    viii. Cooling Tower Ancillary Sites As-Is. Tenant
acknowledges and agrees that Tenant accepts the Cooling Tower Ancillary Sites in
their "as-is" condition, and that Tenant at its own expense shall make any
alterations necessary to make such sites suitable for Tenant's purposes thereon,
subject to Landlord's approval rights set forth above. Tenant, at Tenant's sole
cost and expense, shall keep the Cooling Tower Ancillary Sites in good, safe
condition and repair. Landlord makes no representations respecting the condition
of the Cooling Tower Ancillary Sites or their suitability for operation of the
Cooling Tower Equipment. Landlord shall use its good faith efforts to perform
any repairs to or about the Cooling Tower Ancillary Sites to be performed in
such manner as shall not require Tenant to remove Tenant's Cooling Tower
Equipment from the Cooling Tower Ancillary Sites, but Landlord, on reasonable
advance notice to Tenant, may require Tenant to temporarily remove Tenant's
Cooling Tower Equipment from the Cooling Tower Ancillary Sites if the same is
reasonably required in order to allow Landlord to perform the repairs. Such
removal and the reinstallation of the Cooling Tower Equipment shall be at
Tenant's sole cost and expense.

                    ix. Damage or Destruction; Eminent Domain. A fire or other
casualty or a taking affecting the Cooling Tower Ancillary Sites or the Cooling
Tower Equipment shall not affect the obligations of Tenant under this Lease, and
the Lease shall remain in full force and effect, without any abatement of any
amounts payable to Landlord hereunder. Landlord shall be entitled to all
compensation, damages, income, rent awards and interest thereon whatsoever which
may be paid or made in connection with any taking of the Cooling Tower Ancillary
Sites, and Tenant shall have no claim against Landlord or any governmental
authority for the value of any unexpired term of its rights under this Paragraph
17.i.(b).

                    x. Security. The parties acknowledge that safety and
security devices, services and programs provided by Landlord at the Building and
Building (including without limitation, any such devices and programs affecting
the Cooling Tower Ancillary Sites), if any, may not prevent theft or other
criminal acts, or ensure safety of persons or property or limit access. The risk
that any safety or security device, service or program may not be effective, or
may malfunction, or be circumvented by any party, is assumed by Tenant with
respect to Tenant's property and interests (including without limitation the
Equipment), Tenant shall obtain insurance coverage to the extent Tenant desires
protection against such criminal acts and other losses, and, without limiting
the provisions of Paragraph 14 or Paragraph 28 above, Tenant releases Landlord
and the other Indemnitees from any liability for or in connection with such acts
and losses. Tenant agrees to cooperate in any reasonable safety or security
program developed by Landlord or required by any Legal Requirement.

                    xi. Term of the Licenses. The term of the licenses under
this Paragraph 17.i.(b) shall commence on the date hereof, and, unless
terminated earlier pursuant to this Paragraph 17.i.(b), shall continue through
the Expiration Date or the earlier termination of this Lease.

                                       28

<PAGE>

                    xii. Survival. The indemnities granted by Tenant in this
Paragraph 17.i.(b) shall survive the expiration or earlier termination of the
Lease

            j. Janitorial Service for Ground Floor Premises. Tenant shall be
responsible and arrange for, at its sole cost and expense, all janitorial and
trash removal service for the Ground Floor Premises (including replacement of
restroom supplies for any restrooms located on the Ground Floor Premises). All
of Tenant's rubbish and other debris shall be removed by Tenant from the Ground
Floor Premises at such times and to such location in or about the Building as
may be designated from time to time by Landlord and shall be properly bagged.
Tenant shall at all times during the term of this Lease keep the Ground Floor
Premises in a clean, neat and attractive condition. If Landlord determines that
the Ground Floor Premises are not being maintained in a first-class manner,
Landlord shall have the right, following not less than five (5) Business Day's
prior written notice to Tenant, to provide janitorial services to the Ground
Floor Premises, at Tenant's sole cost and expense. In addition, if in Landlord's
reasonable judgment such service is necessary, upon notice from Landlord, Tenant
shall procure and thereafter maintain a contract providing for extermination
services to the Ground Floor Premises, at Tenant's sole cost and expense. Tenant
shall submit any such contract to Landlord for Landlord's prior written
approval.

            18. Personal Property and Other Taxes. Tenant shall pay, prior to
delinquency, any and all taxes, fees, charges or other governmental impositions
levied or assessed against Landlord or Tenant (a) upon Tenant's equipment,
furniture, fixtures and other personal property (excluding carpeting installed
by Tenant) located in the Premises, (b) by virtue of any Alterations made by
Tenant to the Premises (other than in the nature of ordinary office
improvements), and (c) upon this transaction or any document to which Tenant is
a party creating or transferring an interest or an estate in the Premises. If
any such fee, charge or other governmental imposition is paid by Landlord,
Tenant shall reimburse Landlord for Landlord's payment within thirty (30) days
after demand.

            19. Rules and Regulations. Tenant shall comply with the rules and
regulations set forth on Exhibit B attached hereto, as such rules and
regulations may be modified or amended by Landlord from time to time (the "Rules
and Regulations"), provided that such modifications and amendments do not
discriminate against Tenant, are not in conflict with the provisions of this
Lease, do not materially increase the burdens or obligations upon Tenant, do not
materially reduce Tenant's rights under this Lease, do not impose a charge upon
Tenant for services which this Lease expressly states are to be provided to
Tenant at no charge, and do not materially adversely affect the conduct of any
business in the Premises which Tenant is permitted to conduct pursuant to
Paragraphs 2.g. and 8.a. hereof. Landlord shall not be responsible to Tenant for
the nonperformance or noncompliance by any other tenant or occupant of the
Building of or with any of the Rules and Regulations, but Landlord shall not
enforce the Rules and Regulations in a discriminatory manner. In the event of
any conflict between the Rules and Regulations and the balance of this Lease,
the balance of this Lease shall control.

            20. Surrender; Holding Over.

                a. Surrender. Upon the expiration or other termination of this
Lease, Tenant shall surrender the Premises to Landlord vacant and broom-clean,
with all improvements and Alterations (except as provided below) in their
original condition, except for reasonable wear and tear, damage from casualty or
condemnation and any changes resulting from approved Alterations; provided,
however, that prior to the expiration or termination of this Lease Tenant shall
remove from the Premises any Alterations that Tenant is required by Landlord to
remove under the provisions of this Lease, and all of Tenant's personal property
(including, without limitation, all voice and data cabling) and trade fixtures.
If such removal is not completed at the expiration or other termination of this
Lease, Landlord may remove the same at Tenant's expense. Any damage to the
Premises or the Building caused by such removal shall be repaired promptly by
Tenant (including the patching or repairing of ceilings and walls) or, if Tenant
fails to do so, Landlord may do so at Tenant's expense. The removal of
Alterations from the Premises shall be governed by Paragraph 9 above. Tenant's
obligations under this paragraph shall survive the expiration or other
termination of this Lease. Upon expiration or termination of this Lease or of
Tenant's possession, Tenant shall surrender all keys to the Premises or any
other part of the Building and shall make known to Landlord the combination of
locks on all safes, cabinets and vaults that may be located in the Premises.

                b. Holding Over. If Tenant remains in possession of the Premises
after the expiration or earlier termination of this Lease with the express
written consent of Landlord, Tenant's occupancy shall be a month-to-month
tenancy at a rent agreed upon by Landlord and Tenant, but in no event less than
the greater of (i) one hundred fifty percent (150%) of the Monthly Rent and
Additional Rent payable under this Lease during the last full month prior to the
date of the expiration of this Lease or (ii) the then fair market rental (as
reasonably determined by Landlord) for the Premises. Except as provided in the
preceding sentence, the month-to-month tenancy shall be on

                                       29

<PAGE>

the terms and conditions of this Lease, except that any renewal options,
expansion options, rights of first refusal, rights of first negotiation or any
other rights or options pertaining to additional space in the Building contained
in this Lease shall be deemed to have terminated and shall be inapplicable
thereto. Landlord's acceptance of rent after such holding over with Landlord's
written consent shall not result in any other tenancy or in a renewal of the
original term of this Lease. If Tenant remains in possession of the Premises
after the expiration or earlier termination of this Lease without Landlord's
consent, Tenant's continued possession shall be on the basis of a tenancy at
sufferance and Tenant shall pay as Monthly Rent during the holdover period an
amount equal to the greater of (i) one hundred fifty percent (150%) of the fair
market rental (as reasonably determined by Landlord) for the Premises or (ii)
one hundred seventy five percent (175%) of the Monthly Rent and Additional Rent
payable under this Lease for the last full month prior to the date of such
expiration or termination.

                c. Indemnification. Tenant shall indemnify, defend and hold
Landlord harmless from and against all Claims incurred by or asserted against
Landlord and arising directly or indirectly from Tenant's failure to timely
surrender the Premises, including but not limited to (i) any rent payable by or
any loss, cost, or damages, including lost profits, claimed by any prospective
tenant of the Premises or any portion thereof, and (ii) Landlord's damages as a
result of such prospective tenant rescinding or refusing to enter into the
prospective lease of the Premises or any portion thereof by reason of such
failure to timely surrender the Premises.

            21. Subordination and Attornment.

                a. Within ninety (90) days following the date of this Lease, or
as soon as reasonably possible thereafter, Landlord shall provide Tenant with a
non-disturbance and attornment agreement substantially in the form attached as
Exhibit F hereto from Fleet National Bank, which is the only holder of a
Superior Interest (as defined below) as of the date of this Lease. As used
herein and elsewhere in this Lease, an "Encumbrance" is any mortgage, deed of
trust, ground lease, underlying lease or like encumbrance affecting any part of
the Real Property or any interest of Landlord therein, and the holder of an
Encumbrance that is superior to Tenant's leasehold interest is referred to in
this Lease as the holder of a "Superior Interest."

                b. If an Encumbrance is created following the date of this
Lease, then this Lease shall be automatically subject and subordinate to such
Encumbrance upon delivery to Tenant of a non-disturbance agreement executed by
the holder of the Encumbrance providing that if Tenant is not in default under
this Lease beyond any applicable grace period, that such party will recognize
this Lease and Tenant's rights hereunder and will not disturb Tenant's
possession hereunder, and if this Lease is by operation of law terminated in a
foreclosure, that a new lease will be entered into on the same terms as this
Lease for the remaining term hereof, and including such further matters and
conditions to the foregoing as may be customarily and commercially reasonably
required by the holder of the Encumbrance. Tenant shall, within fifteen (15)
days after Landlord's request, execute and deliver to Landlord a document
evidencing the subordination of this Lease to a particular Encumbrance created
after the date of this Lease, provided that the non-disturbance provisions
provided for in this Paragraph 21. b. are included in such document.

            Notwithstanding anything to the contrary herein, if, in order to
obtain a non-disturbance agreement pursuant to Paragraphs 21.a. or b. hereof,
Landlord is required to expend any sum, Tenant shall reimburse Landlord for such
sums within fifteen (15) days following receipt of Landlord's written request
therefor.

                c. If the interest of Landlord in the Real Property or the
Building is transferred to any person ("Purchaser") pursuant to or in lieu of
proceedings for enforcement of any Encumbrance, Tenant shall immediately attorn
to the Purchaser, and this Lease shall continue in full force and effect as a
direct lease between the Purchaser and Tenant on the terms and conditions set
forth herein upon notice from Landlord of such transfer, subject to the terms of
any applicable non-disturbance agreement.

            22. Financing Condition. If any lender or ground lessor that intends
to acquire an interest in, or holds a mortgage, ground lease or deed of trust
encumbering any portion of the Real Property should require either the execution
by Tenant of (a) an agreement requiring Tenant to send such lender written
notice of any default by Landlord under this Lease and giving such lender the
right to cure such default until such lender is entitled pursuant to the terms
of its mortgage to cure the default and preventing Tenant from terminating this
Lease unless, after such lender is so entitled to cure the default, such lender
does not promptly commence, and diligently continue, to remedy the default
(provided that in no event shall such agreement prohibit Tenant from exercising
its non-termination remedies against Landlord for such breach pursuant to the
terms of the Lease) and/or (b) any modification of the agreements, covenants,
conditions or provisions of this Lease (provided that such modification does not
affect the length of the Lease term, increase the rent payable by Tenant under
Paragraphs 5 and 7 hereof or have a materially adverse affect on Tenant's
rights, or materially

                                       30

<PAGE>

increase Tenant's obligations, under this Lease), then Tenant agrees that it
shall, within ten (10) Business Days after Landlord's request, execute and
deliver such agreement and modify this Lease as required by such lender or
ground lessor. Tenant acknowledges and agrees that if Tenant fails to timely
execute any such agreement required by such lender or ground lessor within such
ten (10) Business Day period, and thereafter Tenant does not deliver such
executed document within ten (10) days of receipt of written notice from
Landlord of such failure, such failure shall constitute an Event of Default and
may cause Landlord serious financial damage by causing the failure of a
financing transaction and giving Landlord all of its rights and remedies under
Paragraph 25 below, including its right to damages caused by the loss of such
financing, but only to the extent any such loss is attributable primarily to
Tenant's failure to deliver any such certificate. If Tenant receives a
non-disturbance agreement from a particular lender pursuant to Paragraph 21
above, the provisions of the non-disturbance agreement, to the extent
inconsistent with the provisions of this Paragraph 22, shall govern as to that
lender.

            23. Entry by Landlord. Landlord may, at any and all reasonable
times, and upon at least one (1) Business Day's advance written notice (provided
that no advance notice need to be given if an emergency (as determined by
Landlord in its reasonable judgment) necessitates an immediate entry or prior to
entry to provide routine janitorial services), enter the Premises to (a) inspect
the same and to determine whether Tenant is in compliance with its obligations
hereunder, (b) supply janitorial and any other service Landlord is required to
provide hereunder, (c) show the Premises to prospective lenders, purchasers or,
during the last eighteen (18) months of the Term, prospective tenants, (d) post
notices of non-responsibility, and (e) alter, improve or repair the Premises or
any other portion of the Real Property. In connection with any such alteration,
improvement or repair, Landlord may erect in the Premises or elsewhere in the
Real Property scaffolding and other structures reasonably required for the work
to be performed. Except as expressly provided below, in no event shall such
entry or work entitle Tenant to an abatement of rent, constitute an eviction of
Tenant, constructive or otherwise, or impose upon Landlord any liability
whatsoever, including, but not limited to, liability for consequential damages
or loss of business or profits by Tenant. Landlord shall use good faith efforts
to cause all such work to be done in such a manner as to cause as little
interference to Tenant as reasonably possible and, subject to Paragraph 17.f.
above, and except to the extent an emergency requires otherwise (as reasonably
determined by Landlord), any extraordinarily noisy or disruptive work shall be
performed after Business Hours or on weekends. If any such entry or work is
necessitated due to reasons within Landlord's reasonable control and continues
for ten (10) or more consecutive Business Days after Tenant's written notice
thereof to Landlord, and during the period of entry or work all or a material
part of the Premises are rendered unusable by such entry or work so that Tenant
is unable to conduct its business in the Premises in substantially the manner as
it was conducted in the Premises prior to such entry or work, and Tenant does
not conduct any business in such part of the Premises so rendered unusable, then
commencing as of the expiration of such ten (10) consecutive Business Day
period, Tenant shall be entitled to an abatement of Monthly Rent under Paragraph
5 hereof and Additional Rent under Paragraph 7 hereof, which abatement shall be
based on the portion of the Premises rendered unusable for Tenant's business by
such entry or work. The prior sentence is inapplicable to Landlord's entry into
the Premises or work within the Premises that is necessitated due to (x) damage
caused by fire or other casualty where such damage is governed by Paragraph 26
or (y) damage caused by the negligence or willful misconduct of Tenant or
Tenant's agents, employees or contractors, or (z) any interruption in, or
failure or inability to provide to Tenant any services or utilities, where such
interruption, failure or inability is governed by Paragraph 17.e. Landlord shall
at all times retain a key with which to unlock all of the doors in the Premises,
except Tenant's vaults and safes. If an emergency necessitates immediate access
to the Premises, Landlord may use whatever force is reasonably necessary to
enter the Premises and any such entry to the Premises shall not constitute a
forcible or unlawful entry into the Premises, a detainer of the Premises, or an
eviction of Tenant from the Premises, or any portion thereof.

            24. Insolvency or Bankruptcy. The occurrence of any of the following
shall constitute an Event of Default under Paragraph 25 below:

                a. Tenant ceases doing business as a going concern, makes an
assignment for the benefit of creditors, is adjudicated an insolvent, files a
petition (or files an answer admitting the material allegations of such
petition) seeking for Tenant any reorganization, arrangement, composition,
readjustment, liquidation, dissolution or similar arrangement under any state or
federal bankruptcy or other law, or Tenant consents to or acquiesces in the
appointment, pursuant to any state or federal bankruptcy or other law, of a
trustee, receiver or liquidator for the Premises, for Tenant or for all or any
substantial part of Tenant's assets; or

                b. Tenant fails within sixty (60) days after the commencement of
any proceedings against Tenant seeking reorganization, arrangement, composition,
readjustment, liquidation, dissolution or similar relief under any state or
federal bankruptcy or other Legal Requirement, to have such proceedings
dismissed, or Tenant fails, within sixty (60) days after an

                                       31

<PAGE>

appointment pursuant to any state or federal bankruptcy or other Legal
Requirement without Tenant's consent or acquiescence, of any trustee, receiver
or liquidator for the Premises, for Tenant or for all or any substantial part of
Tenant's assets, to have such appointment vacated; or

                c. Tenant is unable, or admits in writing its inability, to pay
its debts as they mature; or

                d. Tenant gives notice to any governmental body of its
insolvency or pending insolvency, or of its suspension or pending suspension of
operations.

            In no event shall this Lease be assigned or assignable by reason of
any voluntary or involuntary bankruptcy, insolvency or reorganization
proceedings, nor shall any rights or privileges hereunder be an asset of Tenant,
the trustee, debtor-in-possession, or the debtor's estate in any bankruptcy,
insolvency or reorganization proceedings.

            25. Default and Remedies.

                a. Events of Default. The occurrence of any of the following
shall constitute an "Event of Default" by Tenant:

                    1. Tenant fails to pay when due Monthly Rent, Additional
Rent or any other rent due hereunder and such failure continues for more than
two (2) Business Days after Tenant's actual receipt of written notice from
Landlord; or

                    2. Tenant abandons the Premises within the meaning of
California Civil Code Section 1951.2; or

                    3. Tenant fails to deliver any estoppel certificate pursuant
to Paragraph 29 below, subordination agreement pursuant to Paragraph 21 above,
or document required pursuant to Paragraph 22 above, within the applicable
period set forth therein; or

                    4. Tenant violates the bankruptcy and insolvency provisions
of Paragraph 24 above; or

                    5. Tenant makes or has made or furnishes or has furnished
any warranty, representation or statement to Landlord in connection with this
Lease, or any other agreement made by Tenant for the benefit of Landlord, which
is or was false or misleading in any material respect when made or furnished and
upon which Landlord reasonably relied in making its determination to enter into
this Lease; or

                    6. Tenant assigns this Lease or subleases any portion of the
Premises in violation of Paragraph 13 above; or

                    7. A default by Tenant occurs under any other lease between
Tenant and Landlord or any affiliate of Landlord, and Tenant fails to cure such
default within the applicable period set forth therein; or

                    8. Tenant fails to comply with any other provision of this
Lease in the manner required pursuant to this Lease within thirty (30) days
after written notice from Landlord of such failure (or if the noncompliance
cannot by its nature be cured within the 30 day period, if Tenant fails to
commence to cure such noncompliance within the 30 day period or thereafter fails
to diligently prosecute such cure to completion); except that such thirty (30)
day period shall be shortened as set forth in Landlord's written notice to
Tenant as Landlord reasonably determines is necessary if waiting for such thirty
(30) day period to expire would jeopardize the health, safety or quiet enjoyment
of the Building by its tenants and occupants or cause further damage or loss to
Landlord or the Real Property or result in any violation (or continuance of any
violation) of any Legal Requirement.

                b. Remedies. Upon the occurrence of an Event of Default Landlord
shall have the following remedies, which shall not be exclusive but shall be
cumulative and shall be in addition to any other remedies now or hereafter
allowed by law:

                    1. Landlord may terminate Tenant's right to possession of
the Premises at any time by written notice to Tenant. Tenant expressly
acknowledges that in the absence of such written notice from Landlord, no other
act of Landlord, including, but not limited to, its re-entry into the Premises,
its efforts to relet the Premises, its reletting of the Premises for Tenant's
account, its storage of Tenant's personal property and trade fixtures, its
acceptance of keys to the Premises from Tenant, its appointment of a receiver,
or its exercise of any other rights and remedies under this Paragraph 25 or
otherwise at law, shall constitute an acceptance of Tenant's surrender of

                                       32

<PAGE>

the Premises or constitute a termination of this Lease or of Tenant's right to
possession of the Premises.

            Upon such termination in writing of Tenant's right to possession of
the Premises, this Lease shall terminate and Landlord shall be entitled to
recover damages from Tenant as provided in California Civil Code Section 1951.2
or any other applicable existing or future Legal Requirement providing for
recovery of damages for such breach, including but not limited to the following:

                          (i) The reasonable cost of recovering the Premises;
plus

                          (ii) The reasonable cost of removing Tenant's
Alterations, trade fixtures and improvements (in each case, only to the extent
Tenant is otherwise required to remove the same under this Lease upon the
expiration or sooner termination hereof); plus

                          (iii) All unpaid rent due or earned hereunder prior to
the date of termination, less the proceeds of any reletting or any rental
received from subtenants prior to the date of termination applied as provided in
Paragraph 25.b.2. below, together with interest at the Interest Rate, on such
sums from the date such rent is due and payable until the date of the award of
damages; plus

                          (iv) The amount by which the rent which would be
payable by Tenant hereunder, including Additional Rent under Paragraph 7 above,
as reasonably estimated by Landlord, from the date of termination until the date
of the award of damages, exceeds the amount of such rental loss as Tenant proves
could have been reasonably avoided, together with interest at the Interest Rate
on such sums from the date such rent is due and payable until the date of the
award of damages; plus

                          (v) The amount by which the rent which would be
payable by Tenant hereunder, including Additional Rent under Paragraph 7 above,
as reasonably estimated by Landlord, for the remainder of the then term, after
the date of the award of damages exceeds the amount such rental loss as Tenant
proves could have been reasonably avoided, discounted at the discount rate
published by the Federal Reserve Bank of San Francisco for member banks at the
time of the award plus one percent (1%); plus

                          (vi) Such other amounts in addition to or in lieu of
the foregoing as may be permitted from time to time by applicable law, including
without limitation any other amount necessary to compensate Landlord for all the
detriment proximately caused by Tenant's failure to perform its obligations
under this Lease or which in the ordinary course of things would be likely to
result therefrom.

                    2. Landlord has the remedy described in California Civil
Code Section 1951.4 (a landlord may continue the lease in effect after the
tenant's breach and abandonment and recover rent as it becomes due, if the
tenant has the right to sublet and assign subject only to reasonable
limitations), and may continue this Lease in full force and effect and may
enforce all of its rights and remedies under this Lease, including, but not
limited to, the right to recover rent as it becomes due. After the occurrence of
an Event of Default, Landlord may enter the Premises without terminating this
Lease and sublet all or any part of the Premises for Tenant's account to any
person, for such term (which may be a period beyond the remaining term of this
Lease), at such rents and on such other terms and conditions as Landlord deems
advisable. In the event of any such subletting, rents received by Landlord from
such subletting shall be applied (i) first, to the payment of the costs of
maintaining, preserving, altering and preparing the Premises for subletting, the
other costs of subletting, including but not limited to brokers' commissions,
attorneys' fees and expenses of removal of Tenant's personal property, trade
fixtures and Alterations; (ii) second, to the payment of rent then due and
payable hereunder; (iii) third, to the payment of future rent as the same may
become due and payable hereunder; (iv) fourth, the balance, if any, shall be
paid to Tenant upon (but not before) expiration of the term of this Lease. If
the rents received by Landlord from such subletting, after application as
provided above, are insufficient in any month to pay the rent due and payable
hereunder for such month, Tenant shall pay such deficiency to Landlord monthly
upon demand. Notwithstanding any such subletting for Tenant's account without
termination, Landlord may at any time thereafter, by written notice to Tenant,
elect to terminate this Lease by virtue of a previous Event of Default.

            During the continuance of an Event of Default, for so long as
Landlord does not terminate Tenant's right to possession of the Premises and
subject to Paragraph 13, entitled Assignment and Subletting, and the options
granted to Landlord thereunder, Landlord shall not unreasonably withhold its
consent to an assignment or sublease of Tenant's interest in the Premises or in
this Lease.

<PAGE>

                    3. During the continuance of an Event of Default and after
Tenant's abandonment of the Premises (within the meaning of California Civil
Code 1951.2), Landlord may enter the Premises without terminating this Lease and
remove all Tenant's personal property, Alterations (to the extent Tenant is
otherwise required to remove the same under this Lease upon the expiration or
sooner termination hereof) and trade fixtures from the Premises and store them
at Tenant's risk and expense. If Landlord removes such property from the
Premises and stores it at Tenant's risk and expense, and if Tenant fails to pay
the cost of such removal and storage after written demand therefor and/or to pay
any rent then due, then after the property has been stored for a period of
thirty (30) days or more Landlord may sell such property at public or private
sale, in the manner and at such times and places as Landlord deems commercially
reasonable following reasonable notice to Tenant of the time and place of such
sale. The proceeds of any such sale shall be applied first to the payment of the
expenses for removal and storage of the property, the preparation for and the
conducting of such sale, and for attorneys' fees and other legal expenses
incurred by Landlord in connection therewith, and the balance shall be applied
as provided in Paragraph 25.b.2. above.

            Tenant hereby waives all claims for damages that may be caused by
Landlord's reentering and taking possession of the Premises or removing and
storing Tenant's personal property pursuant to this Paragraph 25, and Tenant
shall indemnify, defend and hold Landlord harmless from and against any and all
Claims resulting from any such act. No reentry by Landlord shall constitute or
be construed as a forcible entry by Landlord.

                    4. Landlord may require Tenant to remove any and all
Alterations from the Premises (but only to the extent Tenant is otherwise
required to remove the same under this Lease upon the expiration or sooner
termination hereof) or, if Tenant fails to do so within ten (10) days after
Landlord's request, Landlord may do so at Tenant's expense.

                    5. Landlord may cure the Event of Default at Tenant's
expense, it being understood that such performance shall not waive or cure the
subject Event of Default. If Landlord pays any sum or incurs any expense in
curing the Event of Default, Tenant shall reimburse Landlord upon demand for the
amount of such payment or expense with interest at the Interest Rate from the
date the sum is paid or the expense is incurred until Landlord is reimbursed by
Tenant. Any amount due Landlord under this subsection shall constitute
additional rent hereunder.

                c. Waiver of Redemption. Tenant hereby waives, for itself and
all persons claiming by and under Tenant, all rights and privileges which it
might have under any present or future Legal Requirement to redeem the Premises
or to continue this Lease after being dispossessed or ejected from the Premises.

            26. Damage or Destruction. If all or any part of the Premises or any
material portion of the balance of the Real Property is damaged by fire or other
casualty, Landlord shall, within sixty (60) days of the date of the damage, give
Tenant written notice of Landlord's reasonable estimate of the time required
from the date of the damage to repair the damage (the "Damage Estimate").
Landlord shall diligently proceed to repair the damage and this Lease shall
remain in full force and effect if (i) the damage is caused by a peril covered
by Landlord's insurance (or required under this Lease to be covered by
Landlord's insurance), the proceeds from such insurance are sufficient to repair
the damage (an "Insured Casualty"), and the Damage Estimate is one hundred
eighty (180) days or less, or (ii) the damage is caused by a peril not covered
(and not required to be covered) by Landlord's insurance or the proceeds from
Landlord's insurance are not sufficient to repair the damage (an "Uninsured
Casualty"), and the Damage Estimate is ninety (90) days or less. If the Damage
Estimate is more than one hundred eighty (180) days, in the case of an Insured
Casualty, or more than ninety (90) days, in the case of an Uninsured Casualty,
Landlord, at its option exercised by written notice to Tenant within sixty (60)
days of the date of the damage, shall either (a) diligently proceed to repair
the damage, in which event this Lease shall continue in full force and effect,
or (b) terminate this Lease as of the date specified by Landlord in the notice,
which date shall be not less than thirty (30) days nor more than sixty (60) days
after the date such notice is given, and this Lease shall terminate on the date
specified in the notice; provided, however, that Landlord may terminate this
Lease pursuant to the foregoing only if Landlord also terminates the leases of
substantially all other tenants of the Building that were, in Landlord's
reasonable judgment, similarly affected by the damage (and under which Landlord
has such a termination right). If the damage is to the Premises or if the
Building is so damaged that access to or use and occupancy of the Premises is
materially impaired, the Damage Estimate is more than one (1) year, and Landlord
does not give notice terminating this Lease within the sixty (60) day period
provided above, then Tenant may give notice to Landlord, within fifteen (15)
calendar days after the expiration of the aforesaid sixty (60) day period,
terminating this Lease as of the date specified in Tenant's termination notice,
which date shall not be before the date of such notice or more than thirty (30)
days after the date of Tenant's termination notice.

                                       34

<PAGE>
            Notwithstanding anything to contrary contained in this Paragraph 26,
if the initial Damage Estimate is more than ninety (90) days, and the date on
which Landlord reasonably anticipates the repairs of such damage will be
completed is during the last twelve (12) months of the Lease term, Landlord and
Tenant shall each have the option to terminate this Lease by giving written
notice to the other, in the case of Landlord together with the Damage Estimate,
or, in the case of Tenant, within thirty (30) days of Tenant's receipt of the
Damage Estimate, and this Lease shall terminate as of the date specified by the
party in its termination notice, which date shall not be before the date of such
notice or more than thirty (30) days after the date of such notice.

            Notwithstanding anything to the contrary in the Paragraph 26, if
damage which would otherwise lead to a right to terminate this Lease results
from the willful misconduct of Landlord or Tenant, the party from whose
misconduct such damage results shall have no right to terminate this Lease.

            If the fire or other casualty damages the Premises or the common
areas of the Real Property necessary for Tenant's use and occupancy of the
Premises, Tenant ceases to use any portion of the Premises as a result of such
damage, and the damage does not result from the negligence or willful misconduct
of Tenant or any other Tenant Parties, then during the period the Premises or
portion thereof are rendered unusable by such damage and repair, Tenant's
Monthly Rent and Additional Rent under Paragraphs 5 and 7 above shall be
proportionately reduced based upon the extent to which the damage and repair
prevents Tenant from conducting, and Tenant does not conduct, its business at
the Premises. Landlord shall not be obligated to repair or replace any of
Tenant's movable furniture, equipment, trade fixtures, and other personal
property, nor any Alterations installed in the Premises by Tenant, and no damage
to any of the foregoing shall entitle Tenant to any abatement, and Tenant shall,
at Tenant's sole cost and expense, repair and replace such items. All such
repair and replacement of Alterations shall be constructed in accordance with
Paragraph 9 above regarding Alterations.

            A total destruction of the Building shall automatically terminate
this Lease. In no event shall Tenant be entitled to any compensation or damages
from Landlord for loss of use of the whole or any part of the Premises or for
any inconvenience occasioned by any such destruction, rebuilding or restoration
of the Premises, the Building or access thereto, except for the rent abatement
expressly provided above. Tenant hereby waives California Civil Code Sections
1932(2) and 1933(4), providing for termination of hiring upon destruction of the
thing hired and Sections 1941 and 1942, providing for repairs to and of
premises.

            27. Eminent Domain.

                  a. If all or any part of the Premises is taken by any public
or quasi-public authority under the power of eminent domain, or any agreement in
lieu thereof (a "taking"), this Lease shall terminate as to the portion of the
Premises taken effective as of the date of taking. If only a portion of the
Premises is taken, Landlord or Tenant may terminate this Lease as to the
remainder of the Premises upon written notice to the other party within ninety
(90) days after the taking; provided, however, that Tenant's right to terminate
this Lease is conditioned upon the remaining portion of the Premises being of
such size or configuration that such remaining portion of the Premises is
unusable or uneconomical for Tenant's business. Landlord shall be entitled to
all compensation, damages, income, rent awards and interest thereon whatsoever
which may be paid or made in connection with any taking and Tenant shall have no
claim against Landlord or any governmental authority for the value of any
unexpired term of this Lease or of any of the improvements or Alterations in the
Premises; provided, however, that the foregoing shall not prohibit Tenant from
prosecuting a separate claim against the taking authority for an amount
separately designated for Tenant's relocation expenses or the interruption of or
damage to Tenant's business or as compensation for Tenant's personal property,
trade fixtures, Alterations or other improvements paid for by Tenant.

            In the event of a partial taking of the Premises which does not
result in a termination of this Lease, the Monthly Rent and Additional Rent
under Paragraphs 5 and 7 hereunder shall be equitably reduced based on the
rentable area of the portion of the Premises taken. If all or any material
portion of the Real Property other than the Premises is taken, Landlord may
terminate this Lease upon written notice to Tenant given within ninety (90) days
after the date of taking, provided that such termination right shall be
conditioned upon Landlord's terminating the leases of all other tenants of the
Building which are similarly affected by the taking and as to which Landlord has
such a termination right.

                  b. Notwithstanding the foregoing, if all or any portion of the
Premises is taken for a period of time of one (1) year or less ending prior to
the end of the term of this Lease, this Lease shall remain in full force and
effect and Tenant shall continue to pay all rent and to perform all of its
obligations under this Lease; provided, however, that Tenant shall be entitled
to all compensation, damages, income, rent awards and interest thereon that is
paid or made in connection

                                       35
<PAGE>

with such temporary taking of the Premises (or portion thereof), except that
fifty percent (50%) of any such compensation in excess of the rent or other
amounts payable to Landlord hereunder shall be promptly paid over to Landlord as
received. Landlord and Tenant each hereby waive the provisions of California
Code of Civil Procedure Section 1265.130 and any other applicable existing or
future Legal Requirement providing for, or allowing either party to petition the
courts of the state in which the Real Property is located for, a termination of
this Lease upon a partial taking of the Premises and/or the Building.

            28. Landlord's Liability; Sale of Building. The term "Landlord," as
used in this Lease, shall mean only the owner or owners of the Real Property at
the time in question. Notwithstanding any other provision of this Lease, the
liability of Landlord for its obligations under this Lease is limited solely to
Landlord's interest in the Real Property as the same may from time to time be
encumbered, and no personal liability shall at any time be asserted or
enforceable against any other assets of Landlord or against the constituent
shareholders, partners, members, or other owners of Landlord, or the directors,
officers, employees and agents of Landlord or such constituent shareholder,
partner, member or other owner, on account of any of Landlord's obligations or
actions under this Lease. In addition, in the event of any conveyance of title
to the Real Property where the transferee assumes in writing all of Landlord's
obligations under this Lease arising from and after the date of the conveyance
of title (subject to the limitations on liability set forth in this Paragraph
28), the grantor or transferor shall be relieved of all liability with respect
to Landlord's obligations to be performed under this Lease after the date of
such conveyance. In no event shall Landlord be deemed to be in default under
this Lease unless Landlord fails to perform its obligations under this Lease,
Tenant delivers to Landlord written notice specifying the nature of Landlord's
alleged default, and Landlord fails to cure such default within thirty (30) days
following receipt of such notice (or, if the default cannot reasonably be cured
within such period, to commence action within such thirty (30)-day period and
proceed diligently thereafter to cure such default). If Tenant provides Landlord
with any security for Tenant's performance of its obligations hereunder,
Landlord shall transfer such security to the grantee or transferee of Landlord's
interest in the Real Property, and upon such transfer Landlord shall be released
from any further responsibility or liability for such security. Notwithstanding
any other provision of this Lease, but not in limitation of the provisions of
Paragraph 14.a. above, Landlord shall not be liable for any consequential
damages or interruption or loss of business, income or profits, nor shall
Landlord be liable for loss of or damage to artwork, currency, jewelry, bullion,
unique or valuable documents, securities or other valuables, or for other
property not in the nature of ordinary fixtures, furnishings and equipment used
in general administrative and executive office activities and functions.
Wherever in this Lease Tenant or Landlord (a) releases the other party from any
claim or liability, (b) waives or limits any right to assert any claim against
the other party or to seek recourse against any property of the other party or
(c) agrees to indemnify the other party against any matters, the relevant
release, waiver, limitation or indemnity shall run in favor of and apply to the
other party, the constituent shareholders, partners, members, or other owners of
the other party, and the directors, officers, employees and agents of the other
party and each such constituent shareholder, partner, member or other owner.

            29. Estoppel Certificates. At any time and from time to time, upon
not less than ten (10) Business Days' prior notice from the other, Landlord and
Tenant shall each execute, acknowledge and deliver to the other a statement
certifying the commencement date of this Lease, stating that this Lease is
unmodified and in full force and effect (or if there have been modifications,
that this Lease is in full force and effect as modified and the date and nature
of each such modification), that, to its knowledge, the requesting party is not
in default under this Lease (or, if it is in default, specifying the nature of
such default), that the party providing the statement is not in default under
this Lease (or, if it is in default, specifying the nature of such default), the
current amounts of and the dates to which the Monthly Rent and Additional Rent
has been paid, and setting forth such other matters as may be reasonably
requested by the requesting party. Any such statement by Tenant may be
conclusively relied upon by a prospective purchaser of the Real Property or by a
lender obtaining a lien on the Real Property as security. Any such statement by
Landlord may be conclusively relied upon by any party providing financing to
Tenant, purchasing an equity interest in Tenant, or entering into a merger,
consolidation or similar transaction with Tenant, provided that the statement by
Landlord was specifically addressed to such relying party (e.g. if Landlord
issues a statement for Tenant's use in a financing by a particular party, Tenant
may not later use the statement for a different party with whom Tenant is
merging and Tenant shall request a new statement by Landlord for such new
party). If Tenant fails to deliver such statement requested by Landlord within
the time required hereunder, such failure shall be conclusive upon Tenant that
(i) this Lease is in full force and effect, without modification except as may
be represented by Landlord, (ii) there are no uncured defaults in Landlord's
performance of its obligations hereunder, (iii) not more than one month's
installment of Monthly Rent has been paid in advance, and (iv) any other
statements of fact included by Landlord in such statement are correct. Tenant
acknowledges and agrees that its failure to execute such certificate may cause
Landlord serious financial damage by causing the failure of a sale or financing
transaction and giving Landlord all of its rights and remedies under Paragraph
25 above, including its right to damages caused by the loss of such sale or
financing.

                                       36
<PAGE>

            30. Right of Landlord to Perform. If Tenant fails to make any
payment required hereunder (other than Monthly Rent and Additional Rent) or
fails to perform any other of its obligations hereunder, Landlord may, upon five
(5) days' prior written notice to Tenant expressly stating Landlord's intention
to exercise its rights under this Paragraph 30 (unless such notice period would
jeopardize the health, safety or quiet enjoyment of the Building by its tenants
and occupants or cause further damage or loss to Landlord or the Real Property),
but shall not be obliged to, and without waiving any default of Tenant or
releasing Tenant from any obligations to Landlord hereunder, make any such
payment or perform any other such obligation on Tenant's behalf. All sums so
paid by Landlord and all necessary incidental costs in connection with the
performance by Landlord of an obligation of Tenant (together with interest
thereon from the date of such payment by Landlord until paid at the Interest
Rate) shall be payable by Tenant to Landlord upon demand, and Tenant's failure
to make such payment upon demand shall entitle Landlord to the same rights and
remedies provided Landlord in the event of non-payment of rent.

            31. Late Charge. Tenant acknowledges that late payment of any
installment of Monthly Rent or Additional Rent or any other amount required
under this Lease will cause Landlord to incur costs not contemplated by this
Lease and that the exact amount of such costs would be extremely difficult and
impracticable to fix. Such costs include, without limitation, processing and
accounting charges, late charges that may be imposed on Landlord by the terms of
any encumbrance or note secured by the Real Property and the loss of the use of
the delinquent funds. Therefore, if any installment of Monthly Rent or
Additional Rent or any other amount due from Tenant is not received within three
(3) Business Days following written notice from Landlord to Tenant that such sum
is past due, Tenant shall pay to Landlord on demand, on account of the
delinquent payment, an additional sum equal to the greater of (i) five percent
(5%) of the overdue amount, or (ii) One Hundred Dollars ($100.00), which
additional sum represents a fair and reasonable estimate of the costs that
Landlord will incur by reason of late payment by Tenant; except that Landlord
shall only be required to give two (2) such notices in any calendar year, and
after two (2) such notices are given any failure by Tenant in such calendar year
to pay Monthly Rent, Additional Rent or any other amount due hereunder on the
date due will subject Tenant to the late charge, without the requirement of
notice from Landlord of such failure. Acceptance of any late charge shall not
constitute a waiver of Tenant's default with respect to the overdue amount, nor
prevent Landlord from exercising its right to collect interest as provided
above, rent, or any other damages, or from exercising any of the other rights
and remedies available to Landlord.

            32. Attorneys' Fees; Waiver of Jury Trial. In the event of any
action or proceeding between Landlord and Tenant (including an action or
proceeding between Landlord and the trustee or debtor in possession while Tenant
is a debtor in a proceeding under any bankruptcy law) to enforce any provision
of this Lease, the losing party shall pay to the prevailing party all costs and
expenses, including, without limitation, reasonable attorneys' fees and
expenses, incurred in such action and in any appeal in connection therewith by
such prevailing party. The "prevailing party" will be determined by the court
before whom the action was brought based upon an assessment of which party's
major arguments or positions taken in the suit or proceeding could fairly be
said to have prevailed over the other party's major arguments or positions on
major disputed issues in the court's decision. Notwithstanding the foregoing,
however, Landlord shall be deemed the prevailing party in any unlawful detainer
or other action or proceeding instituted by Landlord based upon any default or
alleged default of Tenant hereunder if (i) judgment is entered in favor of
Landlord, or (ii) prior to trial or judgment Tenant pays all or any portion of
the rent claimed by Landlord, vacates the Premises, or otherwise cures the
default claimed by Landlord.

            If Landlord becomes involved in any litigation or dispute,
threatened or actual, by or against anyone not a party to this Lease, but
arising by reason of or related to any act or omission of Tenant or any Tenant
Party, Tenant agrees to pay Landlord's reasonable attorneys' fees and other
costs incurred in connection with the litigation or dispute, regardless of
whether a lawsuit is actually filed.

            IF ANY ACTION OR PROCEEDING BETWEEN LANDLORD AND TENANT TO ENFORCE
THE PROVISIONS OF THIS LEASE (INCLUDING AN ACTION OR PROCEEDING BETWEEN LANDLORD
AND THE TRUSTEE OR DEBTOR IN POSSESSION WHILE TENANT IS A DEBTOR IN A PROCEEDING
UNDER ANY BANKRUPTCY LAW) PROCEEDS TO TRIAL, LANDLORD AND TENANT HEREBY WAIVE
THEIR RESPECTIVE RIGHTS TO A JURY IN SUCH TRIAL. Landlord and Tenant agree that
this paragraph constitutes a written consent to waiver of trial by jury within
the meaning of California Code of Civil Procedure Section 631(a)(2), and Tenant
does hereby authorize and empower Landlord to file this paragraph and/or this
Lease, as required, with the clerk or judge of any court of competent
jurisdiction as a written consent to waiver of jury trial.

            33. Waiver. No provisions of this Lease shall be deemed waived by
Landlord or Tenant unless such waiver is in a writing signed by the party giving
such waiver. The waiver by

                                       37
<PAGE>

Landlord or Tenant of any breach of any provision of this Lease shall not be
deemed a waiver of any subsequent breach of the same or any other provision of
this Lease. No delay or omission in the exercise of any right or remedy of
Landlord or Tenant upon any default by the other party shall impair such right
or remedy or be construed as a waiver. Landlord's acceptance of any payments of
rent due under this Lease shall not be deemed a waiver of any default by Tenant
under this Lease (including Tenant's recurrent failure to timely pay rent) other
than Tenant's nonpayment of the accepted sums, and no endorsement or statement
on any check or accompanying any check or payment shall be deemed an accord and
satisfaction. Landlord's consent to or approval of any act by Tenant requiring
Landlord's consent or approval shall not be deemed to waive or render
unnecessary Landlord's consent to or approval of any subsequent act by Tenant.

            34. Notices. All notices and demands which may or are required to be
given by either party to the other hereunder shall be in writing. All notices
and demands by Landlord to Tenant shall be delivered personally or sent by
United States mail, certified, return receipt requested, postage prepaid, or by
any reputable overnight or same-day courier, addressed to Tenant at the
Premises, Att'n: General Counsel, or to such other place as Tenant may from time
to time designate by notice to Landlord hereunder; provided, however, that prior
to the Commencement Date, notices to Tenant shall be addressed to Tenant at Ask
Jeeves, Inc., 5858 Horton Street, Suite 350, Emeryville, CA 94608, Att'n:
General Counsel. All notices and demands by Tenant to Landlord shall be sent by
United States mail, postage prepaid, or by any reputable overnight or same-day
courier, addressed to Landlord in care of Shorenstein Company LLC, 555
California Street, 49th floor, San Francisco, California 94104, Attn: Corporate
Secretary, with a copy to the management office of the Building, or to such
other place as Landlord may from time to time designate by notice to Tenant
hereunder. Notices delivered personally or sent same-day courier will be
effective immediately upon delivery to the addressee at the designated address;
notices sent by overnight courier will be effective one (1) Business Day after
acceptance by the service for delivery; notices sent by mail will be effective
three (3) Business Days after mailing. In the event Tenant requests multiple
notices hereunder, Tenant will be bound by such notice from the earlier of the
effective times of the multiple notices.

            35. Deleted.

            36. Defined Terms and Marginal Headings. When required by the
context of this Lease, the singular includes the plural. If more than one person
or entity signs this Lease as Tenant, the obligations hereunder imposed upon
Tenant shall be joint and several, and the act of, written notice to or from,
refund to, or signature of, any Tenant signatory to this Lease (including,
without limitation, modifications of this Lease made by fewer than all such
Tenant signatories) shall bind every other Tenant signatory as though every
other Tenant signatory had so acted, or received or given the written notice or
refund, or signed. The headings and titles to the paragraphs of this Lease are
for convenience only and are not to be used to interpret or construe this Lease.
Wherever the term "including" or "includes" is used in this Lease it shall be
construed as if followed by the phrase "without limitation." The language in all
parts of this Lease shall in all cases be construed as a whole and in accordance
with its fair meaning and not construed for or against any party simply because
one party was the drafter thereof.

            37. Time and Applicable Law. Time is of the essence of this Lease
and of each and all of its provisions. This Lease shall be governed by and
construed in accordance with the laws of the State of California, and the venue
of any action or proceeding under this Lease shall be the County of Alameda,
California.

            38. Successors. Subject to the provisions of Paragraphs 13 and 28
above, the covenants and conditions hereof shall be binding upon and inure to
the benefit of the parties hereto and their respective heirs, personal
representatives, successors, executors, administrators and assigns.

            39. Entire Agreement; Modifications. This Lease (including any
exhibit, rider or attachment hereto) constitutes the entire agreement between
Landlord and Tenant with respect to Tenant's lease of the Premises. No provision
of this Lease may be amended or otherwise modified except by an agreement in
writing signed by the parties hereto. Neither Landlord nor Landlord's agents
have made any representations or warranties with respect to the Premises, the
Building, the Real Property or this Lease except as expressly set forth herein,
including without limitation any representations or warranties as to the
suitability or fitness of the Premises for the conduct of Tenant's business or
for any other purpose, nor has Landlord or its agents agreed to undertake any
alterations or construct any improvements to the Premises except those, if any,
expressly provided in this Lease, and no rights, easements or licenses shall be
acquired by Tenant by implication or otherwise unless expressly set forth
herein. Neither this Lease nor any memorandum hereof shall be recorded by
Tenant.

            40. Light and Air. Tenant agrees that no diminution of light, air or
view by any structure which may hereafter be erected (whether or not by
Landlord) shall entitle Tenant to any

                                       38
<PAGE>

reduction of rent hereunder, result in any liability of Landlord to Tenant, or
in any other way affect this Lease.

            41. Name of Building. Tenant shall not use the name of the Building
for any purpose other than as the address of the business conducted by Tenant in
the Premises without the written consent of Landlord. Landlord reserves the
right to change the name of the Building at any time in its sole discretion by
written notice to Tenant and Landlord shall not be liable to Tenant for any
loss, cost or expense on account of any such change of name.

            42. Severability. If any provision of this Lease or the application
thereof to any person or circumstance shall be invalid or unenforceable to any
extent, the remainder of this Lease and the application of such provisions to
other persons or circumstances shall not be affected thereby and shall be
enforced to the greatest extent permitted by law.

            43. Authority. If Tenant is a corporation, partnership, trust,
association or other entity, Tenant and each person executing this Lease on
behalf of Tenant, hereby covenants and warrants that (a) Tenant is duly
incorporated or otherwise established or formed and validly existing under the
laws of its state of incorporation, establishment or formation, (b) Tenant has
and is duly qualified to do business in the state in which the Real Property is
located, (c) Tenant has full corporate, partnership, trust, association or other
appropriate power and authority to enter into this Lease and to perform all
Tenant's obligations hereunder, and (d) each person (and all of the persons if
more than one signs) signing this Lease on behalf of Tenant is duly and validly
authorized to do so.

            44. No Offer. Submission of this instrument for examination and
signature by Tenant does not constitute an offer to lease or a reservation of or
option for lease, and is not effective as a lease or otherwise until execution
and delivery by both Landlord and Tenant.

            45. Real Estate Brokers. Landlord and Tenant each represents and
warrants to the other that such party has negotiated this Lease directly with
the Real Estate Broker(s) identified in Paragraph 2 ("Brokers") and has not
authorized or employed, or acted by implication to authorize or to employ, any
other real estate broker or salesperson to act for such party in connection with
this Lease. Each party shall hold the other harmless from and indemnify and
defend the other against any and all Claims by any real estate broker or
salesperson other than the Broker for a commission, finder's fee or other
compensation as a result of the inaccuracy of such party's representation above.

            46. Consents and Approvals. Wherever the consent, approval, judgment
or determination of Landlord is required or permitted under this Lease,
Landlord's consent, approval, judgment or determination shall not be
unreasonably made or withheld (as applicable), unless the provision providing
for such consent, approval, judgment or determination specifies that Landlord's
consent or approval shall be in Landlord's sole discretion, or otherwise
specifies the standards under which Landlord may withhold its consent. Whenever
Tenant requests Landlord to take any action or give any consent or approval,
Tenant shall reimburse Landlord for all of Landlord's reasonable costs incurred
in reviewing the proposed action or consent (whether or not Landlord consents to
any such proposed action), including without limitation reasonable attorneys' or
consultants' fees and expenses, within ten (10) days after Landlord's delivery
to Tenant of a statement of such costs. If it is determined that Landlord failed
to give its consent or approval where it was required to do so under this Lease,
Tenant's sole remedy will be an order of specific performance or mandatory
injunction of the Landlord's agreement to give its consent or approval;
provided, however, that Tenant shall be entitled to seek damages as a remedy if
the remedy of specific performance or injunction is by its nature impossible to
render. The review and/or approval by Landlord of any item shall not impose upon
Landlord any liability for accuracy or sufficiency of any such item or the
quality or suitability of such item for its intended use. Any such review or
approval is for the sole purpose of protecting Landlord's interest in the Real
Property, and neither Tenant nor any Tenant Party nor any person or entity
claiming by, through or under Tenant, nor any other third party shall have any
rights hereunder by virtue of such review and/or approval by Landlord.

            47. Reserved Rights. Landlord retains and shall have the rights set
forth below, exercisable without notice and without liability to Tenant for
damage or injury to property, person or business and without effecting an
eviction, constructive or actual, or disturbance of Tenant's use or possession
of the Premises or giving rise to any claim for rent abatement:

                  a. To grant to anyone the exclusive right to conduct any
business or render any service in or to the Building and its tenants, provided
that such exclusive right shall not operate to require Tenant to use or
patronize such business or service or to exclude Tenant from its use of the
Premises expressly permitted herein.

                                       39
<PAGE>

                  b. To perform, or cause or permit to be performed, at any time
and from time to time, including during Business Hours, construction in the
common areas and facilities or other leased areas in the Real Property.

                  c. To reduce, increase, enclose or otherwise change at any
time and from time to time the size, number, location, lay-out and nature of the
common areas and facilities and other tenancies and premises in the Real
Property and to create additional rentable areas through use or enclosure of
common areas; provided that, (i) if the rentable square footage of the Building
is increased or decreased, Tenant's Share shall be proportionately adjusted (but
in no event shall Tenant's Share under Paragraph 2.e. above be affected by a
change in the square footage of any of the common areas during the Lease term)
and (ii) in no event may any such change to the common areas have a materially
adverse affect on Tenant's access to the Premises.

            48. Financial Statements. Upon submission of this Lease to Landlord
and at any time thereafter within thirty (30) days after Landlord's request
therefor, Tenant shall furnish to Landlord copies of true and accurate (in all
material respects) financial statements reflecting Tenant's then current
financial situation (including, without limitation, balance sheets, statements
of profit and loss, and changes in financial condition), and Tenant's most
recent audited or certified annual financial statements. Tenant agrees to
deliver to any lender, prospective lender, purchaser or prospective purchaser
designated by Landlord such financial statements of Tenant as may be reasonably
requested by such lender or purchaser.

            49. Deleted.

            50. Nondisclosure of Lease Terms. Tenant agrees that the terms of
this Lease are confidential and constitute proprietary information of Landlord,
and that disclosure of the terms hereof could adversely affect the ability of
Landlord to negotiate with other tenants. Tenant hereby agrees that Tenant and
its partners, officers, directors and employees shall not deliver a copy of this
Lease, or disclose the terms of this Lease, to any other person without
Landlord's prior written consent, except to any accountants of Tenant in
connection with the preparation of Tenant's financial statements or tax returns,
to an assignee of this Lease or sublessee of the Premises, to a purchaser of
Tenant's assets or stock, to an entity with which Tenant is intending to merge,
or to an entity or person to whom disclosure is required by applicable law
(including, without limitation, the Securities Exchange Commission) or in
connection with any action brought to enforce this Lease. Tenant further agrees
that it will inform any party to whom Tenant gives a copy of this Lease or
discloses the terms hereof as permitted above, of the confidential nature of
this Lease and the terms hereof, and require that such party execute a
confidentiality agreement reasonably designed to ensure the confidentiality of
this Lease and its terms, and under which Landlord shall be expressly named as a
third party beneficiary and entitled to damages for the breach thereof.

            51. Hazardous Substance Disclosure. California law requires
landlords to disclose to tenants the existence of certain hazardous substances.
Accordingly, the existence of gasoline and other automotive fluids, maintenance
fluids, copying fluids and other office supplies and equipment, certain
construction and finish materials, tobacco smoke, cosmetics and other personal
items, and asbestos-containing materials ("ACM") must be disclosed. Gasoline and
other automotive fluids are found in the garage area of the Building. Cleaning,
lubricating and hydraulic fluids used in the operation and maintenance of the
Building are found in the utility areas of the Building not generally accessible
to Building occupants or the public. Many Building occupants use copy machines
and printers with associated fluids and toners, and pens, markers, inks, and
office equipment that may contain hazardous substances. Certain adhesives,
paints and other construction materials and finishes used in portions of the
Building may contain hazardous substances. Although smoking is prohibited in the
public areas of the Building, these areas may, from time to time, be exposed to
tobacco smoke. Building occupants and other persons entering the Building from
time-to-time may use or carry prescription and non-prescription drugs, perfumes,
cosmetics and other toiletries, and foods and beverages, some of which may
contain hazardous substances.

            52. No Discrimination. Tenant covenants by and for itself and its
successors, heirs, personal representatives and assigns and all persons claiming
under or through Tenant that there shall be no discrimination against or
segregation of any person or of a group of persons on account of race, color,
religion, creed, sex or national origin in the leasing, subleasing,
transferring, use, occupancy, tenure or enjoyment of the Premises nor shall
Tenant or any person claiming under or through Tenant establish or permit any
such practice or practices of discrimination or segregation with reference to
the selection, location, number, use or occupancy of tenants, lessees,
sublessees, subtenants or assignees of the Premises.

            53. Parking.

                  a. Commencing upon the Commencement Date, Landlord shall
provide Tenant, on an unassigned, non-exclusive and unlabelled basis,
twenty-eight (28) parking spaces in the parking garage of the Building and
twenty-eight (28) parking spaces in the parking facility presently known as the
City Center Garage West, located at 1250 Martin Luther King Jr. Way, Oakland,
and Tenant shall pay Landlord or the operator of the subject garage, as directed
by Landlord, for such parking at the rate or charge in effect from time to time
for parking in the garage. Notwithstanding the foregoing, in no event may the
monthly charge for the twenty-eight (28) parking spaces located within the
parking garage of the Building increase during the Lease term by more than five
percent (5%) per annum, on a cumulative basis, over the charge in effect as of
the Commencement Date of this Lease. The aforementioned cap on increases in the
parking charge shall be inapplicable to the twenty-eight (28) parking spaces
located in the City Center Garage West. Tenant acknowledges that the monthly and
hourly rates or charges in effect may vary from time to time based on, among
other things, the time of day, type of parking (e.g., valet, self-park, or
tandem) and general rate increases.

                  b. Tenant shall provide Landlord with advance written notice
of the names of each individual to whom Tenant from time to time distributes
Tenant's parking rights hereunder, and shall cause each such individual to
execute Landlord's standard waiver form for garage users. If the parking charge
for a particular parking space is not paid when due, Landlord may terminate
Tenant's right under this Lease to such parking space only if the past due
charge for that parking space is not paid to Landlord within fifteen (15) days
after written notice of such failure from Landlord to Tenant (with such notice
to Tenant meaning notice to the named Tenant, and notice to the individual to
whom the parking space has been assigned shall not suffice for such notice). In
no event may Landlord terminate this Lease due to non-payment of parking
charges. Further, if at any time Tenant releases to Landlord any parking space
provided for in this Paragraph 53, then Tenant's right under this Paragraph 53
to use such released parking space shall automatically forever terminate.

                  c. The parking spaces to be made available to Tenant hereunder
may contain a reasonable mix of spaces for compact cars. Landlord shall take
reasonable actions to ensure the availability of the parking spaces leased by
Tenant, but Landlord does not guarantee the availability of those spaces at all
times against the actions of other tenants of the Building and users of the
parking facility. Without limiting the foregoing, in no event shall this Lease
be void or voidable, nor shall Landlord be liable to Tenant for any loss or
damage, nor shall there be any abatement of rent hereunder (other than the
parking charge paid hereunder for any parking space no longer made available),
by reason of any reduction in Tenant's parking rights hereunder by reason of
strikes, lock-outs, labor disputes, shortages of material or labor, fire, flood
or other casualty, acts of God or any other cause beyond the control of
Landlord. Access to the parking spaces to be made available to Tenant shall, at
Landlord's option, be by card, pass, bumper sticker, decal or other appropriate
identification issued by Landlord, and Tenant's right to use the parking
facility is conditioned on Tenant's abiding by and shall otherwise be subject to
such reasonable rules and regulations as may be promulgated by Landlord from
time to time for the parking facility. The parking rights provided hereunder
shall accrue to an assignee of Tenant's interest in the Lease. Further, in the
event of a sublease, Tenant may permit the subtenant to utilize the parking
spaces provided for hereunder on the terms hereof, not to exceed such
subtenant's prorata allocation of the parking spaces based on the size of the
sublet premises.

            54. Signage; Lobby Directory.

                  a. Premises Entry Signage. Tenant may, at Tenant's expense,
install a sign identifying Tenant's business at the entrances to the Ground
Floor Premises and the 4th and 5th Floor Premises, provided that the design,
size, color and location of the signs shall be in accordance with the Building's
signage criteria and subject to Landlord's prior written approval, which
approval may be granted or withheld in Landlord's sole but good faith
discretion.

                  b. Building Exterior Signage.

                     i. Building Exterior Signage; Occupancy Requirement. The
rights granted to Tenant under this Paragraph 54.b. are exclusive to the Tenant
originally named herein, which is Ask Jeeves, Inc., a Delaware corporation, and
shall not inure to the benefit of any subtenant or assignee of Tenant other than
a Permitted Signage Assignee, as hereinafter defined. For purposes of the
foregoing, a "Permitted Signage Assignee" is an entity to which Tenant's right,
title and interest in this Lease has been assigned pursuant to Paragraph 13.g.
above and which (i) has a net worth of not less than the net worth of Ask
Jeeves, Inc., as of the date of this Lease or as of the date of the assignment
of the Lease to such entity, whichever is greater, (ii) continues to operate a
software engineering and internet application business substantially similar to
the business operated by Ask Jeeves, Inc., as of the date of this Lease and
(iii) has an industry reputation not materially less favorable than that of Ask
Jeeves, Inc. as of the date of this Lease, as reasonably determined by

                                       41
<PAGE>

Landlord. If Ask Jeeves, Inc., changes its name to a name other than Ask Jeeves,
Inc., but continues to operate a software engineering and internet application
business substantially similar to the business operated by Ask Jeeves, Inc., as
of the date of this Lease, then such name change shall not affect Tenant's
rights under this Paragraph 54.b.

                     Subject to the provisions of this Paragraph 54.b., Tenant
shall have the exclusive right to erect and maintain the Exterior Signage (as
defined in Paragraph 54.b.ii. below) on both the north and south parapet signage
sites at the top of the Building (the "Signage Sites"). Tenant shall have the
right to install and maintain the Exterior Signage on the Signage Sites only if
Tenant originally named herein leases and is actually in occupancy of, and
conducting business in, not less than 32,013 rentable square feet of space
within the Building (the foregoing criteria being referred to hereinafter as the
"Occupancy Requirements."). Notwithstanding the foregoing, during the period
that Tenant is actively constructing the Initial Alterations in the Premises
pursuant to Paragraph 4 above, Tenant shall be deemed to have satisfied the
Occupancy Requirements. If, at any time after the date hereof, Tenant ceases to
satisfy the Occupancy Requirements, then Landlord shall have the right, at any
time thereafter and exercisable by written notice to Tenant, to terminate
Tenant's right to the Exterior Signage and to require Tenant to remove the
Exterior Signage from the Signage Sites in accordance with the removal
requirements of Paragraph 54.b.iii. below. If Tenant fails at any time to
satisfy the Occupancy Requirements, but Landlord does not send written notice to
Tenant requiring that the Exterior Signage be removed from the Signage Sites,
Landlord's failure to send such notice shall not constitute a wavier by Landlord
of its right to require Tenant to remove the Exterior Signage from the Signage
Sites and Landlord may, at any time thereafter, send Tenant the written notice
requiring Tenant to remove the Exterior Signage from the Signage Sites in
accordance with the requirements of Paragraph 54.b.iii. below and, upon receipt
of such written notice, Tenant shall remove the Exterior Signage in accordance
with the requirements of Paragraph 54.b.iii. below. Once Tenant has failed to
satisfy the Occupancy Requirements, Tenant's subsequent satisfaction of the
Occupancy Requirements shall not reinstate Tenant's rights to the Exterior
Signage under this Paragraph 54.b. and, if Landlord has not previously required
that Tenant remove the Exterior Signage due to Tenant's failure to satisfy the
Occupancy Requirements at an earlier date, Landlord may still send such written
notice requiring Tenant to remove the Exterior Signage from the Signage Sites
notwithstanding the fact that Tenant, as of the date of the written notice,
again satisfies the Occupancy Requirements.

            If Tenant has not installed the Exterior Signage on the Signage
Sites on or before the date that is one (1) year following the earlier of (x)
the date Tenant commences business in any portion of the Premises or (y)
December 1, 2004 (such one (1) year period to be extended by the length of any
delay in the installation of the Exterior Signage caused by Landlord) then
Tenant's rights under this Paragraph 54.b. shall automatically and forever
terminate without notice; provided, however, that, if Tenant has not installed
the Exterior Signage by the end of such one (1) year period (as the same may
have been extended by delays caused by Landlord) because Tenant is then
contemplating a name change or is then actively pursuing a merger with another
entity, then such one (1) year period shall be extended through the earlier of
(i) date that Tenant has reached a decision regarding its name or the date that
the merger is consummated, whichever is applicable, or (ii) the date that is six
(6) months following the end of the one (1) year period (as such one (1) year
period may have been extended by Landlord delay). If Tenant has not installed
the Exterior Signage by the end of the one (1) year period (as the same may have
been extended due to Landlord delay) and Tenant requests the extension provided
for above due to a contemplated name change or merger, Tenant shall, with five
(5) business days Landlord's written request, provide reasonable written
evidence to Landlord that the name change is actually being contemplated or the
merger is being actively pursued, whichever is applicable.

                  ii. Installation and Maintenance of Exterior Signage. The
Exterior Signage shall contain only Tenant's name and/or logo, shall be subject
to Landlord's prior written approval (in Landlord's sole but good faith
discretion) with regard to size, design, color, materials, content, location and
method of installation, and shall be appropriate for a first-class high rise
office building, in conformity with the overall design and ambiance of the Real
Property and in compliance with all applicable Legal Requirements. Landlord's
approval of any item reviewed by Landlord under this Paragraph 54.b.ii. shall
merely indicate Landlord's consent to the proposed work shown thereon, and in no
event shall be deemed to constitute a representation by Landlord that the work
called for therein complies with applicable building codes or other Legal
Requirements nor shall such consent release Tenant from Tenant's obligations to
supply plans and specifications that do so conform to applicable building codes
and Legal Requirements. The cost of the design, manufacture, installation and
lighting (if any) of the Exterior Signage shall be borne by Tenant and the
Alterations Allowance provided for in Paragraph 4.b. above may not be applied to
such costs. Tenant shall be responsible for obtaining, at Tenant's sole cost and
expense, any and all necessary zoning and other public or private approvals and
permits required for the Exterior Signage (provided that in doing so Tenant
shall not adversely affect Landlord or impair in any way Landlord's current or
permitted use of the Real Property and provided, further, that Landlord makes no
representation whatsoever that any of the foregoing items

                                       42
<PAGE>

may be obtained). Landlord represents to Tenant that Landlord is not presently
aware of any private (as opposed to public) approvals or permits required for
the Exterior Signage. Landlord will reasonably cooperate with Tenant in its
efforts to obtain such approvals and permits, provided that Landlord shall not
be required to incur any costs in connection therewith. The Exterior Signage, as
approved by Landlord in writing, may not be modified, replaced or removed
without Landlord' prior written approval, in Landlord's sole but good faith
discretion. Landlord shall grant its approval or disapproval (including specific
reasons for disapproval) to any proposed Exterior Signage or modification
thereto within twenty (20) days following Landlord's receipt of Tenant's written
request therefor.

                        The installation of the Exterior Signage shall be
performed by contractors approved in advance by Landlord in writing (and
Tenant's contract with such contractors shall be subject to Landlord's prior
review and reasonable written approval) and in accordance with Landlord's
reasonable construction and insurance requirements (which insurance requirements
shall include liability insurance with coverage of $25,000,000.00 per
occurrence/general aggregate, with such policies naming Landlord and its agents
and other reasonable designees as additional insureds; provided, however, if the
installation of the Exterior Signage does not utilize a helicopter, then the
general contractor performing the installation may have coverage of not less
than $10,000,000.00, but only if the insurance carried by the subcontractors
utilized by the general contractor for the installation provides coverage of not
less than $15,000,000.00, so that a total of not less than $25,000,000.00 in
coverage is available with regard to the installation).

                        During the period that the Exterior Signage is installed
on the Signage Sites, Tenant shall, at Tenant's sole cost, maintain the Exterior
Signage in a good and first class condition appropriate for a first class office
Building in downtown Oakland or the San Francisco Financial District and in
accordance with all applicable Legal Requirements; provided, however, at
Landlord's election, Landlord may perform any such cleaning, maintenance, repair
or modification of the Exterior Signage or other portions of the Real Property
required to effect compliance with Legal Requirements, in which event, Tenant
shall pay the costs of such work to Landlord within thirty (30) days after
receipt of Landlord's invoice therefor. Tenant's access to the roof of the
Building for purposes of installing, maintaining and removing the Exterior
Signage shall be in accordance with Landlord's reasonable requirements regarding
roof access.

                  iii. Removal of Exterior Signage. Upon the expiration or
earlier termination of this Lease, or if Tenant is required by Landlord pursuant
to Paragraph 54.b.i. above to the remove the Exterior Signage during the term
hereof, or if Tenant desires to remove the Exterior Signage during the term
hereof, or if Legal Requirements no longer permit the Exterior Signage to remain
on the Signage Sites for any reason, Tenant shall, at Tenant's sole cost and
expense, remove the Exterior Signage from the Signage Sites and repair and
restore the affected areas of the Building and Real Property to their original
condition at the time the Exterior Signage was installed, ordinary wear and tear
excepted; provided, however, at Landlord's election upon written notice to
Tenant, Landlord may perform the foregoing removal and restoration work, in
which event Tenant shall pay the costs of such work to Landlord within thirty
(30) days after receipt of Landlord's invoice therefor. If Landlord does not
elect to perform the removal and restoration work pursuant to the foregoing, the
removal and restoration work shall be performed by contractors approved in
advance by Landlord in writing (and Tenant's contract with such contractors
shall be subject to Landlord's prior review and reasonable written approval) and
in accordance with Landlord's reasonable construction and insurance requirements
(which insurance requirements shall be the same as those set forth in Paragraph
54.b.ii. above for the installation of the Exterior Signage). Tenant's
obligations regarding the removal of the signage and restoration of the affected
areas of the Building and Real Property shall survive the expiration or sooner
termination of this Lease.

            If the Exterior Signage is removed from the Signage Sites during the
term hereof in accordance with the provisions of this Paragraph 54.b.iii., this
Lease shall not be void or voidable, nor shall Tenant be entitled to a reduction
in rent under the Lease or any other compensation or damages.

                  iv. Reimbursement of Landlord's Costs; Repair of Damage;
Waiver and Indemnification.

                        (a) Reimbursement of Landlord's Costs. Tenant shall
reimburse Landlord for any and all out-of-pocket costs reasonably incurred by
Landlord in connection with the installation, existence or removal of the
Exterior Signage pursuant to this Paragraph 54.b., including, without
limitation, costs of retaining engineers or other consultants to review the
design, weight, construction and/or manner of installation of the Exterior
Signage, and costs incurred by Landlord in connection with the issuance of the
permits required for the installation of the Exterior Signage, which
reimbursement shall be made within thirty (30)days of Landlord's written demand,
which written demand shall specify the particular costs for which Landlord is
requesting reimbursement hereunder.

                                       43
<PAGE>

                        (b) Repair of Damage. Tenant shall, at Tenant's sole
cost, repair any and all damage caused to the Building or any other portion of
the Real Property as a result of the installation, existence or removal of the
Exterior Signage, except to the extent such damage is caused by the gross
negligence or willful misconduct of Landlord. Such repair shall be performed by
contractors reasonably approved by Landlord in advance pursuant to contracts
reasonably approved by Landlord, and such work shall be performed in accordance
with Landlord's construction procedures and insurance requirements.

                        (c) Waiver and Indemnification. Landlord and the holders
of any Superior Interests (as defined in Paragraph 21.c. above) shall not be
liable to Tenant and Tenant hereby waives all claims against such parties for
any loss, injury or other damage to the Exterior Signage from any cause
whatsoever, including without limitation, water leakage of any character from
the roof or walls, or gas, fire, explosion, or any malfunction within the Real
Property, or acts of other tenants of, or persons entering, the Building or roof
of the Building; provided, however, that the foregoing waiver shall be
inapplicable to any loss, injury or damage resulting from Landlord's gross
negligence or willful misconduct.

                  Tenant shall hold Landlord and the other Indemnitees (as
defined in Paragraph 14.b. above) harmless from and indemnify the Indemnitees
against any and all Claims (as defined in Paragraph 14.b. above), including
consequential damages, to the extent arising from any accident, injury or
damage, howsoever and by whomsoever caused, to any person or property
(including, without limitation, the Real Property), occurring in connection with
the Exterior Signage (including, without limitation, the installation, existence
or removal thereof) except to the extent such Claims are caused directly by the
gross negligence or willful misconduct of Landlord or its authorized
representatives. In case any action or proceeding be brought against any of the
Indemnitees by reason of any such Claim, Tenant, upon notice from Landlord,
covenants to resist and defend at Tenant's sole expense such action or
proceeding by counsel reasonably satisfactory to Landlord. The provisions of
this paragraph shall survive the expiration or earlier termination of this Lease
with respect to any event occurring covered hereby that occurred prior to such
expiration or termination.

                  c. Building Directory. Tenant shall be entitled, at no cost to
Tenant, to have the name of Tenant's company listed on the Building directory
situated in the lobby of the Building, as well as Tenant's pro rata share of
additional lines on such directory (based upon the rentable square footage of
the Premises) for the listing of Tenant's departments and subtenants. If, after
Tenant's name is initially listed on the directory, Tenant requests a change in
Tenant's name as printed thereon, Tenant shall reimburse Landlord for Landlord's
cost of reprinting Tenant's name for the directory.

            55. License for Tenant's Standby Generator. The provisions of this
Paragraph 55 are personal to Ask Jeeves, Inc., a Delaware corporation, and any
Permitted Generator Assignee (as hereinafter defined) and shall not apply to any
other assignee, subtenant or other occupant of the Premises. For purposes of the
foregoing, a "Permitted Generator Assignee" is an entity to which Tenant's
right, title and interest in this Lease has been assigned pursuant to Paragraph
13.g. above and which continues to operate a software engineering and internet
application business substantially similar to the business operated by Ask
Jeeves, Inc., immediately prior to the assignment.

                        a. License. Effective as of the Commencement Date and
continuing through the term of this Lease, as the same may be extended (unless
terminated earlier pursuant to the provisions of this Paragraph 55) Landlord
hereby grants to Tenant and Tenant hereby accepts from Landlord, a license (the
"License") to use the following portions of the Building:

                  (i) on an non-exclusive basis, in common with Landlord only,
an area not to exceed 2,000 square feet in size (the "Generator Site") to be
designated by Landlord and located within the area on the mezzanine level of the
Building that is outlined on Exhibit D attached hereto, for purposes of the
installation, operation, maintenance and replacement by Tenant, at Tenant's sole
expense, of either one (1) self contained 1,000 kilowatt diesel generator with
diesel fuel tank, or two (2) self contained 500 kilowatt diesel generators with
diesel fuel tank (collectively the "Generator") to provide electrical power to
the Ground Floor Premises (and the Ground Floor Premises only) in the event of a
failure of the electrical service to the Ground Floor Premises, the exact design
of the Generator and manner of installation to be subject to Landlord's written
prior approval in accordance with the terms below;

                  (ii) on a non-exclusive basis, in common with one or more
other tenants or licensees of the Building and Landlord, a pathway, as more
particularly shown or described in plans to be approved by Landlord pursuant to
Paragraph 55.e. below for the installation of up to six (6) conduits, not
exceeding four (4) inches each in diameter, containing electrical wires and
cables (the "Lines") as reasonably needed to connect the Generator with the
Ground Floor Premises.

                                       44
<PAGE>

                  The Lines and the Generator, and any replacement, alteration,
addition or installation thereof approved by Landlord pursuant to this Paragraph
55 are collectively referred to herein as the "Equipment". The Generator Site
and the areas of the Building in which the Lines shall be located are
collectively referred to herein as the "Ancillary Sites".

            b. Lease Provisions Applicable. The provisions of the other sections
of this Lease shall apply to the Ancillary Sites and this License (except to the
extent inconsistent with the provisions of this Paragraph 55). Without limiting
the generality of the foregoing, the provisions of Paragraph 14 (Indemnification
of Landlord), Paragraph 15 (Insurance) and Paragraph 20 (Surrender; Holding
Over), shall apply in full to Tenant's License of the Ancillary Sites and
Tenant's installation, operation and maintenance of the Equipment. If Tenant
fails to perform any of its obligations under this Paragraph 55 and such failure
continues for ten (10) days after written notice thereof from Landlord (or if
the failure cannot by its nature be cured within the 10-day period, if Tenant
fails to commence to cure such failure within the 10-day period and thereafter
diligently prosecute such cure to completion), such failure shall constitute an
Event of Default entitling Landlord to the remedies under Paragraph 25.b. of the
Lease and, in addition to the other remedies set forth in Paragraph 25.b. for an
Event of Default, upon such Event of Default, Landlord may terminate the License
granted hereunder by written notice to Tenant. Notwithstanding anything to the
contrary herein, Landlord shall not be obligated to provide any water, gas,
electricity or other utilities to the Ancillary Sites. Without limiting
Paragraph 14.b. of the Lease, Tenant expressly agrees to indemnify, defend and
save harmless Landlord and the other Indemnitees from and against all Claims
arising (or claimed to have arisen) from the installation, maintenance and
operation of the Lines or the Equipment, except to the extent arising from the
gross negligence or willful misconduct of Landlord or any other Indemnitee. In
addition to the provisions of Paragraph 28 of this Lease, Landlord shall in no
event be liable for any loss or damage to the Equipment, or for any losses or
damages arising out of or in connection with any loss or damage to the Equipment
or failure of the Equipment to operate when needed (except to the extent caused
by the gross negligence or willful misconduct of Landlord's or its employees' or
agents') and Tenant shall install and maintain the Equipment in such manner as
to protect it against damage and disruption.

                  c. Approval, Identification; Specifications.

                        i. Landlord's Approvals or Requirements. Landlord's
approval of, or requirements concerning, the Lines, the Equipment or any plans
and specifications, contractors and subcontractors for the design or
installation thereof, shall not be deemed a waiver of any of the provisions of
this Lease, nor a warranty as to the adequacy of the design, workmanship or
quality of materials or installation or compliance with applicable Legal
Requirements, and Landlord shall have no responsibility or liability for the
same. Landlord shall have no responsibility for any deficiencies in drawings
submitted by Tenant for approval by Landlord or any failure of such drawings to
reflect actual conditions (concealed or apparent) at the Building, including
without limitation any failure of the drawings to reflect existing equipment,
walls or other facilities. In the case any such drawings are deficient, Landlord
may require that Tenant stop the installation work and revise the drawings. Any
matters not specifically reflected in the drawings (including for example, but
not limited to, the height of any proposed wall penetration or the height at
which the Lines will be run) shall be subject to Landlord's prior written
approval, which may be withheld in Landlord's reasonable discretion.

                        ii. Identification. Tenant shall cause Tenant's
personnel or contractor(s) to clearly mark (including any color coding required
by the Building) the Generator and each conduit, cable, wire and piece of
equipment comprising the Lines with the License number assigned by the Building
management and the starting point and the destination of such conduit, cable or
wire (e.g. "No. 100, Ground to Suite 100"), and shall place such identification
tags in each closet, if any, that the Lines pass through, on each horizontal run
of the Lines, and on each item of equipment that is part of the Lines.

                        iii. Line Specifications. To the extent applicable, all
Lines shall comply with the specifications and requirements established by
Landlord from time to time.

                  d. Impositions; Charges. Tenant shall be responsible for and
promptly pay all additional real and personal property taxes, assessments,
charges, fees or other governmental impositions levied or assessed on the
Building, the Real Property, Landlord or Tenant due to the Equipment or the
construction, operation or removal thereof. In addition, Tenant shall pay to
Landlord within fifteen (15) days following written demand, an amount equal to
the reasonable and actual out-of-pocket costs incurred by Landlord in connection
with the installation of the Equipment (or any subsequent modification to, or
replacement of, the Equipment), which costs shall include, without limitation,
any costs incurred by Landlord in retaining third party engineers or consultants
for the review of Tenant's plans and/or for oversight of the construction (which
oversight shall be solely for the benefit of Landlord and shall in no event be a
substitute for Tenant's obligation to retain such project management or other
services as shall be necessary to ensure that the work is performed properly and
in accordance with the requirements of this Paragraph 55).

                                       45
<PAGE>

                  e. Installation Plans. Tenant shall submit to Landlord for
Landlord's prior approval detailed plans and specifications (in form acceptable
to Landlord) for the Equipment to be installed by Tenant on the Ancillary Sites.
Further, Tenant shall submit to Landlord detailed plans and specifications for
any subsequent modification or replacement of the Equipment. Tenant shall not
commence any such installation, modification or replacement until such plans and
specifications have been approved in writing by Landlord and Tenant shall have
submitted such evidence as Landlord shall reasonably require evidencing that
Tenant has obtained all necessary governmental approvals and permits for
installation and operation of the Equipment. Further, no work shall commence
until Landlord has received from Tenant the insurance required by Landlord, in
accordance with Landlord's construction procedures for the Building, for
Tenant's contractor(s) performing the work. Landlord shall have no
responsibility for, and Tenant holds Landlord harmless from, any failure of
Tenant's Equipment to function properly notwithstanding the fact that Landlord
may have approved plans and specifications therefor. Tenant shall keep the
Ancillary Sites and the Building free from any liens arising out of any work
performed, materials furnished or obligations incurred with respect to the
Equipment. Tenant shall install, maintain and operate the Equipment in a safe
manner that shall not overburden or otherwise adversely affect any walls,
floors, ceilings or any other structural or nonstructural elements in the
Building or the electrical system therein. Tenant shall give Landlord not less
than ten (10) days prior written notice of the commencement of any construction
or installation under this Paragraph 55. If required by Landlord, Tenant shall
obtain opinions from engineers reasonably acceptable to Landlord (or at
Landlord's sole discretion, shall reimburse Landlord's out of pocket and
reasonable costs for obtaining such opinions directly) stating that the Lines
and work to be done with respect thereto will not adversely affect other lines
or equipment at the Building, the Building systems and equipment (including
without limitation, electrical, heating, ventilating, air-conditioning,
plumbing, alarm and fire protection), or the Building structure. At all times
during the term of this Lease, Tenant shall maintain with Landlord a current and
complete record of all Tenant's Lines in the Building.

                  f. Use; Compliance With Law. Tenant agrees that Tenant shall
not sell the services of the Equipment, or otherwise use the Equipment to
provide services to any party other than Tenant or to any other location other
than the Premises. Landlord makes no representation that Tenant's contemplated
use of the Lines or the Ancillary Sites will comply with applicable Legal
Requirements. Tenant, at Tenant's sole expense, shall comply with all Legal
Requirements regarding the installation, construction, operation and maintenance
of the Equipment, and shall be solely responsible for obtaining and shall obtain
and keep in force all permits, licenses and approvals necessary for operation of
the Equipment (provided that in doing so Tenant shall not adversely affect
Landlord or impair in any way Landlord's current and permitted use of the
Building). If at any time during the term of the License such permits or
approvals shall expire and are not renewed within thirty (30) days after the
expiration thereof, or if applicable Legal Requirements shall otherwise not
permit the Equipment to remain or be operated on the Ancillary Sites, Tenant
shall promptly remove the Equipment in accordance with the provisions set forth
below applicable to Tenant's removal of the Equipment upon the expiration or
earlier termination of the License.

                  Tenant shall not use any portion of the Ancillary Sites for
the storage, generation or handling of Hazardous Materials without the express
written prior consent of Landlord (which consent may be withheld by Landlord in
its sole discretion), and then only to the extent that the presence of the
Hazardous Materials is (i) properly licensed and approved by all appropriate
governmental officials and in accordance with all applicable Legal Requirements
and (ii) in compliance with any terms and conditions stated in said prior
written approval by Landlord. Tenant shall promptly provide Landlord with copies
of all notices received by it, including, without limitation, any notice of
violations, notice of responsibility or demand for action from any federal,
state or local authority or official in connection with the presence of
Hazardous Materials in or about the Ancillary Sites or any other portion of the
Real Property. In the event of any release of Hazardous Materials upon the
Ancillary Sites or any other portion of the Real Property, or upon adjacent
lands, if caused by Tenant or Tenant's agents, employees, contractors, licensees
or invitees, Tenant shall promptly remedy the problem in accordance with all
applicable Legal Requirements.

                  Notwithstanding anything to the contrary in this Paragraph
55.f., Tenant may utilize diesel fuel for the operation of the Equipment,
provided that Tenant complies with all applicable Legal Requirements regarding
the handling, storage and use of such fuel, as more particularly provided above.
Tenant shall not store diesel fuel other than in the storage tank which is a
part of the Equipment.

                  Without limiting any of the foregoing, (x) Tenant's use and
operation of the Generator shall be in compliance with all Legal Requirements
applying to noise and (y) the size and construction of the diesel fuel tank that
is a part of the Generator shall comply with all applicable Legal Requirements.

                  g. Fueling and Testing of Tenant's Generator Equipment;
Limited Purpose and Use of Equipment. If Tenant desires to have the Generator
fueled, Tenant shall, at Tenant's sole cost, arrange for a third party supplier
of diesel fuel to supply the fuel by means approved in advance by

                                       46
<PAGE>

Landlord. Tenant acknowledges and agrees that Landlord has no responsibility for
fueling, or making arrangements to fuel, the Generator, and, without limiting
the foregoing, in the event of an interruption in, or failure or inability to
provide fuel to the Generator (a "Fuel Interruption") such Fuel Interruption
shall not impose upon Landlord any liability whatsoever (including, without
limitation, liability for consequential damages or loss of business by Tenant)
and Tenant hereby waives all claims against Landlord or the Indemnitees for any
loss or damage resulting from any such Fuel Interruption.

                  Tenant may turn on the Equipment for the purpose of testing
the Equipment only during non-business hours on non-Business Days of the
Building. Further, Tenant shall provide Landlord with not less than two (2)
Business Days prior notice that testing will occur and shall have appropriately
trained representatives present for the testing. Tenant shall comply with any
and all reasonable requirements of Landlord in connection with such testing.

                  Tenant agrees that the Equipment may be used only for
providing electrical power to the Ground Floor Premises during an interruption
in the Building's normal source of electrical power; including, without
limitation, providing standby electrical power to the Cooling Tower Equipment
(as defined in Paragraph 55 above). Accordingly, except for turning the
Equipment on for testing pursuant to the immediately preceding grammatical
paragraph, the Equipment shall not be turned on unless electricity is not being
provided to the Ground Floor Premises.

                  h. Removal of Equipment. The Equipment shall be and remain
Tenant's property throughout the term of the License granted hereunder. Upon the
expiration or any sooner termination of the License, or if Tenant is required to
remove the Equipment by any governmental agency having jurisdiction over the
Equipment, Tenant shall immediately, at its sole expense, remove all of the
Equipment from the Ancillary Sites and restore any damage caused by the
installation or removal thereof.

                  i. Access to Ancillary Sites. Subject to the notice
requirements hereinafter set forth, Tenant shall have the right, at Tenant's
sole cost and expense, to enter upon the Ancillary Sites to construct, install,
operate and maintain the Equipment on the Ancillary Sites until the License
terminates. Tenant may access the Ancillary Sites and perform construction work
therein in accordance with the plans and specifications approved by Landlord
pursuant to Paragraph 55.e. above. Tenant may have access to the Ancillary Sites
for normal repairs during the business hours of the Building upon not less than
twenty-four (24) hours' prior telephone notice to the Building manager (or such
other representative of Landlord as may be designated by Landlord from time to
time by notice to Tenant) and otherwise in accordance with the rules and
procedures (including scheduling requirements) of the Building as in effect from
time to time for such access and work. Tenant may access the Ancillary Sites for
emergency repairs in accordance with such rules and procedures of the Building
as in effect from time to time for such emergency access and work. A
representative of Landlord shall be entitled to be present any time Tenant
wishes to access the Ancillary Sites (including emergency access), and Tenant
shall not access the Ancillary Sites at any time without such representative
unless Landlord shall have expressly waived such requirement in writing.
Landlord may allow access to the Ancillary Sites to any persons who show
evidence which, in the sole good faith judgment and discretion of Landlord,
appears to constitute authorization by Tenant or by any other tenant granted
rights by Landlord to install, operate and/or maintain facilities or equipment
of any kind in such areas of the Building, or by any representative or agent of
Landlord for such access. Tenant shall reimburse Landlord for Landlord's costs
of monitoring and/or supervising Tenant's activities in connection with the
License granted hereunder (including, without limitation, Landlord's
engineering, security or other personnel costs), and such costs shall be payable
by Tenant within fifteen (15) days of billing; provided, however, such
reimbursement shall be inapplicable to Landlord's cost of monitoring and
supervising the initial installation of the equipment or the subsequent
replacement thereof, in which instances the five percent (5%) fee provided for
in Paragraph 55.d. above shall instead apply.

                  j. Landlord's Liability. Landlord shall have no obligation to
design, install, construct, use, operate, maintain, repair, replace or remove
Tenant's Equipment nor any other responsibility or liability in connection
therewith.

                  k. Repair. Tenant acknowledges and agrees that Tenant accepts
the Ancillary Sites in their "as-is" condition, and that Tenant at its own
expense shall make any alterations necessary to make such sites suitable for
Tenant's purposes thereon, subject to Landlord's approval rights set forth
above. Tenant, at Tenant's sole cost and expense, shall keep the Ancillary Sites
in good, safe condition and repair. Landlord makes no representations respecting
the condition of the Ancillary Sites or their suitability for operation of the
Equipment. Landlord shall use its good faith efforts to perform any repairs to
or about the Ancillary Sites to be performed in such manner as shall not require
Tenant to remove Tenant's Equipment from the

                                       47
<PAGE>

Ancillary Sites, but Landlord, on reasonable advance notice to Tenant, may
require Tenant to temporarily remove Tenant's Equipment from the Ancillary Sites
if the same is reasonably required in order to allow Landlord to perform the
repairs. Such removal and the reinstallation of the Equipment shall be at
Tenant's sole cost and expense.

                  l. Deleted.

                  m. Damage or Destruction; Eminent Domain. A fire or other
casualty or a taking affecting the Ancillary Sites or the Equipment shall not
affect the obligations of Tenant under this Lease, and the Lease shall remain in
full force and effect, without any abatement of any amounts payable to Landlord
hereunder, except that the license fee provided for in Paragraph 55.q. below, if
applicable, shall be fully abated during any period that the Generator Site is
not available for use by Tenant due to casualty or condemnation. Landlord shall
be entitled to all compensation, damages, income, rent awards and interest
thereon whatsoever which may be paid or made in connection with any taking of
the Ancillary Sites, and Tenant shall have no claim against Landlord or any
governmental authority for the value of any unexpired term of its rights under
this Paragraph 55.

                  n. Security. The parties acknowledge that safety and security
devices, services and programs provided by Landlord at the Building and Building
(including without limitation, any such devices and programs affecting the
Ancillary Sites), if any, may not prevent theft or other criminal acts, or
ensure safety of persons or property or limit access. The risk that any safety
or security device, service or program may not be effective, or may malfunction,
or be circumvented by any party, is assumed by Tenant with respect to Tenant's
property and interests (including without limitation the Lines), Tenant shall
obtain insurance coverage to the extent Tenant desires protection against such
criminal acts and other losses, and, without limiting the provisions of
Paragraph 14 or Paragraph 28 above, Tenant releases Landlord and the other
Indemnitees from any liability for or in connection with such acts and losses.
Tenant agrees to cooperate in any reasonable safety or security program
developed by Landlord or required by any Legal Requirement.

                  o. Term of the License. The term of the License shall commence
on the date hereof, and, unless terminated earlier pursuant to this Paragraph
55, shall continue through the Expiration Date or the earlier termination of
this Lease.

                  p. Evacuation. If Landlord closes the Building and calls for
its evacuation by means of written or oral notice to the Ground Floor Premises
(which notice may be personal, telephonic, or by means of the Building's public
address system), or suggests by means of written or oral notice to the Ground
Floor Premises (which notice may be personal, telephonic, or by means of the
Building's public address system) that the Building be evacuated for any reason,
including because of an electrical failure, and if one or more of Tenant's
owners, officers, directors, employees, contractors, agents, licensees, invitees
or other persons acting on behalf of or at the request, or with permission, of
Tenant (collectively, "Tenant's Personnel") remain in or later enter the
Building or the Ground Floor Premises during the evacuation period, then Tenant
hereby waives all Claims against Landlord and the Indemnitees for any injury
incurred by any of Tenant's Personnel, or injury to property, due in whole or in
part to Tenant's failure to evacuate all of Tenant's Personnel from the Ground
Floor Premises and the Building. Further Tenant will hold the Indemnitees
harmless from and defend and indemnify them against any and all Claims incurred
by them as a direct or indirect result of Tenant's Personnel remaining in the
Ground Floor Premises or the Building during such evacuation period.

                  q. Fee for use of Generator Site. No fee shall be charged for
the License granted under this Paragraph 55 if the Generator Site is one
thousand (1,000) square feet or less in size. However, if the Generator Site is
more than one thousand (1,000) square feet in size, then Tenant shall pay to
Landlord during the term of this Lease a license fee in the initial amount of
Twelve Dollars ($12.00) per rentable square foot per annum for each square foot
of the Generator Site that exceeds 1,000 square feet, with such sum to be
increased annually by three per cent (3%). The aforementioned fee shall be paid
in equal monthly installments, in advance, on the first day of each calendar
month along with Tenant's payment of Monthly Rent under Paragraph 5 above. The
license fee shall constitute rent under this Lease.

                  r. Survival. The indemnities granted by Tenant in this
Paragraph 55 shall survive the expiration or earlier termination of the Lease.

                  56. Renewal Option.

                        a. Option to Renew. Tenant shall have the option to
renew this Lease for one (1) additional term of five (5) years (the "Extension
Term"), commencing upon the expiration of the initial term of this Lease. The
renewal option must be exercised, if at all, by written notice given by Tenant
to Landlord not later than one (1) year prior to expiration of the initial term
of this Lease. Notwithstanding the foregoing, at Landlord's election, the
renewal option shall be null and void and Tenant shall have no right to renew
this Lease pursuant thereto if on the date Tenant exercises the option or on the
date immediately preceding the commencement of the renewal period (i) the Tenant
originally named in this Lease is not in occupancy of at least 32,013 rentable
square

                                       48
<PAGE>

feet of space under this Lease or such Tenant does not intend to continue to
occupy at least 32,013 retable square feet of space under this Lease, or (ii)
Tenant is in default of any of its obligations under this Lease.

                        b. Terms and Conditions. If Tenant exercises the renewal
option, then all of the terms and conditions set forth in this Lease as
applicable to the Premises during the initial term shall apply during such
Extension Term, except that (i) Tenant shall have no further right to renew this
Lease, (ii) Tenant shall take the Premises in their then "as-is" state and
condition, (iii) the Monthly Rent payable by Tenant for the Premises (the
"Renewal Rent") shall be the then-Fair Market Rent for the Premises based upon
the terms of this Lease, as renewed, (iv) the Base Year for the Premises shall
be the calendar year in which the Extension Term commences, and (v) the Base Tax
Year shall be the fiscal tax year in which the Extension Term commences. Fair
Market Rent shall include the periodic rental increases, if any, that would be
included for space leased for the period the space will be covered by the Lease.
For purposes of this Paragraph 56, the term "Fair Market Rent" shall mean the
rental rate for comparable space under primary lease (and not sublease) to new
tenants, taking into consideration the unique quality and prestige of the
Building and such amenities as existing improvements, view, floor on which the
Premises are situated and the like, situated in first-class, reputable,
established high-rise office buildings of comparable age in comparable locations
in downtown Oakland, in comparable physical and economic condition, taking into
consideration (regardless of whether the same shall increase or decrease the
Fair Market Rent) the Base Year and the Base Tax Year for escalation and the
escalation provisions of this Lease, the load factor, Tenant's renewal rights
under this Lease, the quality of the Building and level of Building services,
the location of the Building, existing improvements (if any), the presence or
absence of asbestos in the Building, and such amenities as view, floor on which
the space is situated and the like, any differences between the absence of any
tenant concessions for the Extension Term, including, without limitation, tenant
improvement allowances and free rent periods for construction or otherwise, and
any brokerage or leasing commissions payable by Landlord, and the
then-prevailing ordinary rental market practices with respect to tenant
concessions (if any). The Fair Market Rent shall be mutually agreed upon by
Landlord and Tenant in writing within the thirty (30) calendar day period
commencing six (6) months prior to commencement of the renewal period. If
Landlord and Tenant are unable to agree upon the Fair Market Rent within said
thirty (30)-day period, then the Fair Market Rent shall be established by
appraisal in accordance with the procedures set forth in Paragraph 56.c. below.

                        c. Appraisal. Within fifteen (15) days after the
expiration of the thirty (30)-day period set forth in Paragraph 56.b. above for
the mutual agreement of Landlord and Tenant as to the Fair Market Rent, each
party hereto, at its cost, shall engage a real estate broker (each a "Qualified
Broker") to act on its behalf in determining the Fair Market Rent. The Qualified
Brokers each shall have at least ten (10) years' experience with leases in
first-class high-rise office buildings in downtown Oakland and shall submit to
Landlord and Tenant in advance for Landlord's and Tenant's reasonable approval
the appraisal methods to be used. If a party does not appoint a Qualified Broker
within such fifteen (15)-day period but a Qualified Broker is appointed by the
other respective party, the single Qualified Broker appointed shall be the sole
Qualified Broker and shall set the Fair Market Rent. If the two Qualified
Brokers are appointed by the parties as stated in this paragraph, such Qualified
Brokers shall meet promptly and attempt to set the Fair Market Rent. If such
Qualified Brokers are unable to agree within thirty (30) days after appointment
of the second Qualified Broker, the Qualified Brokers shall elect a third
Qualified Broker meeting the qualifications stated in this paragraph within ten
(10) days after the last date the two Qualified Brokers are given to set the
Fair Market Rent. Each of the parties hereto shall bear one-half (1/2) the cost
of appointing the third Qualified Broker and of the third Qualified Broker's
fee. The third Qualified Broker shall be a person who has not previously acted
in any capacity for either party.

                           The third Qualified Broker shall conduct his own
investigation of the Fair Market Rent, and shall be instructed not to advise
either party of his determination of the Fair Market Rent except as follows:
When the third Qualified Broker has made his determination, he shall so advise
Landlord and Tenant and shall establish a date, at least five (5) days after the
giving of notice by the third Qualified Broker to Landlord and Tenant, on which
he shall disclose his determination of the Fair Market Rent. Such meeting shall
take place in the third Qualified Broker's office unless otherwise agreed by the
parties. After having initialed a paper on which his determination of Fair
Market Rent is set forth, the third Qualified Broker shall place his
determination of the Fair Market Rent in a sealed envelope. Landlord's Qualified
Broker and Tenant's Qualified Broker shall each set forth their determination of
Fair Market Rent on a paper, initial the same and place them in sealed
envelopes. Each of the three envelopes shall be marked with the name of the
party whose determination is inside the envelope.

                        In the presence of the third Qualified Broker, the
determination of the Fair Market Rent by Landlord's Qualified Broker and
Tenant's Qualified Broker shall be opened and examined. Using the Fair Market
Rent provided by Landlord's Qualified Broker and Tenant's

                                       49
<PAGE>

Qualified Broker, Landlord and Tenant shall determine the Average Monthly Rent
(as defined below) with respect to each Qualified Broker's determination of the
Fair Market Rent. As used herein, "Average Monthly Rent" shall mean, with
respect to each Qualified Broker's determination of Fair Market Rent, the amount
derived by dividing such Qualified Broker's assessment of the total Fair Market
Rent due with respect to the entire Extension Term by the number of months in
such Extension Term. If the higher of the two determinations of Average Monthly
Rent is one hundred five percent (105%) or less of the amount set forth in the
lower determination, the average of the two (2) determinations of Fair Market
Rent shall be the Fair Market Rent, the envelope containing the determination of
the Fair Market Rent by the third Qualified Broker shall be destroyed and the
third Qualified Broker shall be instructed not to disclose his determination. If
either party's envelope is blank, or does not set forth a determination of Fair
Market Rent, the determination of the other party shall prevail and be treated
as the Fair Market Rent. If the higher of the two (2) determinations of Average
Monthly Rent is more than one hundred five percent (105%) of the amount of the
lower determination, the envelope containing the third Qualified Broker's
determination shall be opened. Using the Fair Market Rent provided by each of
the three Qualified Brokers, Landlord and Tenant shall determine the Average
Monthly Rent with respect to each Qualified Broker's determination of Fair
Market Rent. If the value of Average Monthly Rent determined by the third
Qualified Broker is the average of the Average Monthly Rent values proposed by
Landlord's Qualified Broker and Tenant's Qualified Broker, the third Qualified
Broker's determination of Fair Market Rent shall be the Fair Market Rent. If
such is not the case, Fair Market Rent shall be the rent proposed by whichever
of Landlord's Qualified Broker's or Tenant's Qualified Broker's determination of
Average Monthly Rent is closest to the determination of Average Monthly Rent by
the third Qualified Broker.

                        d. Minimum Rental. Notwithstanding anything in the
foregoing to the contrary, in no event shall the Monthly Rent during the renewal
period be less than the aggregate of the amounts of Monthly Rent and Additional
Rent payable by Tenant (for all of the Premises leased hereunder) under
Paragraphs 2.b., 5 and 7 hereof for the calendar month immediately preceding the
commencement of the renewal period.

         THIS LEASE IS EXECUTED by Landlord and Tenant as of the date set forth
at the top of page 1 hereof.

Gail E. McCann, Esq.
Edwards & Angell, LLP
2800 Financial Plaza
Providence, Rhode Island  02903

                      LEASE SUBORDINATION, NON-DISTURBANCE
                            AND ATTORNMENT AGREEMENT

            This agreement ("Lease Subordination, Non-Disturbance and Attornment
Agreement" or "Agreement") is made as of the ____ day of __________, 200__,
among FLEET NATIONAL BANK, a national banking association having a place of
business at 111 Westminster Street, Suite 800, Providence, Rhode Island 02903,
as Administrative Agent ("Agent") for itself and the other institutions who from
time to time become Lenders under a Loan Agreement among Borrower, Agent, and
Lenders relating to the Property (as defined below), 555 TWELFTH STREET VENTURE,
LLC, a Delaware limited liability company, having an address in care of
Shorenstein Company, L.P., 555 California Street, San Francisco, California
94104, Attn.: Corporate Secretary ("Landlord" or "Borrower"),
______________________________, a _______________________________, having a
place of business at 555 Twelfth Street, Oakland, California ("Tenant").

                             Introductory Provisions

            A. Lenders are making a loan to Borrower ("Loan") to be secured by,
among other things, a Deed of Trust, Assignments of Rents, Security Agreement
and Fixture Filing ("Deed of Trust") given by Borrower to Agent covering
property which may be known as 555 Twelfth Street, Oakland, California as more
particularly described on Exhibit A ("Property"), and a Collateral Assignment of
Leases and Rents ("Assignment") from Borrower to Agent with respect to the
Property. The Deed of Trust, the Assignment and related documents are
collectively called the "Deed of Trust Documents".

            B. Tenant is the tenant under that certain lease ("Lease") dated
_______________________________, as may be amended, made with Landlord, covering
a portion (the "Premises") of the Property as more particularly described in the
Lease.

            C. Agent and Lenders require, as a condition to the making and
maintaining of the Loan, that the Deed of Trust be and remain superior to the
Lease and that their rights under the Assignment be recognized.

            D. Tenant requires as a condition to the Lease being subordinate to
the Deed of Trust that its rights under the Lease be recognized.

                                       1
<PAGE>

            E. Agent, on behalf of Lenders, Landlord, and Tenant desire to
confirm their understanding with respect to the Deed of Trust and the Lease.

            NOW, THEREFORE, in consideration of the foregoing, the mutual
covenants and agreements contained herein, and other valuable consideration, the
receipt and adequacy of which are hereby acknowledged, and with the
understanding by Tenant that Lenders shall rely hereon in making and maintaining
the Loan, Agent, Landlord, and Tenant agree as follows:

            1. SUBORDINATION. The Lease and the rights of Tenant thereunder are
subordinate and inferior to the Deed of Trust Documents and any amendment,
renewal, substitution, extension or replacement thereof and each advance made
thereunder as though the Deed of Trust Documents, and each such amendment,
renewal, substitution, extension or replacement were executed and recorded, and
the advance made, before the execution of the Lease. Without limiting the
foregoing and notwithstanding any other term or provision of this Agreement,
Tenant's rights with respect to proceeds of insurance and of eminent domain
awards are expressly made subject and subordinate to the rights of Agent and
Lenders, and the disposition of such proceeds shall be governed by the Deed of
Trust Documents, and the other "Loan Documents" referred to therein, in all
respects.

            2. NON-DISTURBANCE. So long as Tenant is not in default (beyond any
period expressed in the Lease within which Tenant may cure such default) in the
payment of rent or in the performance or observance of any of the terms,
covenants or conditions of the Lease on Tenant's part to be performed or
observed, (a) Tenant's occupancy of the Premises shall not be disturbed by Agent
or Lenders in the exercise of any of their rights under the Deed of Trust
Documents during the term of the Lease, or any extension or renewal thereof made
in accordance with the terms of the Lease, and (b) Lender will not join Tenant
as a party defendant in any action or proceeding for the purpose of terminating
Tenant's interest and estate under the Lease because of any default under the
Deed of Trust Documents.

            3. ATTORNMENT AND CERTIFICATES. In the event Agent or Lenders
succeed to the interest of Borrower as Landlord under the Lease, or if the
Property or the Premises are sold pursuant to the remedies relating to the Deed
of Trust Documents, Tenant shall attorn to Agent, Lenders, or a purchaser upon
any such foreclosure sale, and shall recognize Agent, Lenders, or such
purchaser, thereafter as the Landlord under the Lease. Such attornment shall be
effective and self-operative without the execution of any further instrument.
Tenant agrees, however, to execute and deliver at any time and from time to
time, upon the request of any holder(s) of any of the indebtedness or other
obligations secured by the Deed of Trust Documents, or upon request of any such
purchaser, (a) any instrument or certificate which, in the reasonable judgment
of such holder(s), or such purchaser, may be necessary or appropriate in any
such foreclosure proceeding or otherwise to evidence such attornment, and (b) an
instrument or certificate regarding the status of the Lease, consisting of
statements, if true (and if not true, specifying in what respect), that (i) the
Lease is in full force and effect, (ii) the date through which rentals have been
paid, (iii) the duration and date of the commencement of the term of the Lease,
(iv) the nature of any amendments or modifications to the Lease, (v) to the best
of Tenant's knowledge, that no default, or state of facts, which with the
passage of time, or notice, or both, would constitute a default, exists on the
part of either party to the Lease, and (vi) the dates on which payments of
additional rent, if any, are due under the Lease.

            4. LIMITATIONS. If Agent or Lenders exercise any of their rights
under the Deed of Trust Documents, or if Agent or Lenders shall succeed to the
interest of Landlord under the Lease in any manner, or if any purchaser acquires
the Property, or the Premises, upon or after any foreclosure of the Deed of
Trust, or any deed in lieu thereof, Agent, Lenders or such purchaser, as the
case may be, shall have the same remedies by entry, action or otherwise in the
event of any default by Tenant (beyond any

                                       2
<PAGE>

period expressed in the Lease within which Tenant may cure such default) in the
payment of rent or in the performance or observance of any of the terms,
covenants and conditions of the Lease on Tenant's part to be paid, performed or
observed that the Landlord had or would have had if Lender or such purchaser had
not succeeded to the interest of the present Landlord. From and after any such
attornment, Agent, Lenders or such purchaser shall be bound to Tenant under all
the terms, covenants and conditions of the Lease, and Tenant shall, from and
after such attornment to Agent, Lenders, or to such purchaser, have the same
remedies against Agent, Lenders, or such purchaser, for the breach of an
agreement contained in the Lease that Tenant might have had under the Lease
against Landlord, if Agent, Lenders or such purchaser had not succeeded to the
interest of Landlord. Provided, however, that Agent, Lenders or such purchaser
shall only be bound during the period of their ownership, and that in the case
of the exercise by Agent or Lenders of their rights under the Deed of Trust
Documents or a foreclosure, or deed in lieu of foreclosure, all Tenant claims
shall be satisfied only out of the interest, if any, of Agent, Lenders, or such
purchaser, in the Property, and Agent, Lenders and such purchaser shall not be
(a) liable for any act or omission of any prior landlord (including the
Landlord); or (b) liable for or incur any obligation with respect to the
construction of the Property or any improvements of the Premises or the
Property; or (c) subject to any offsets or defenses which Tenant might have
against any prior landlord (including the Landlord); or (d) bound by any rent or
additional rent which Tenant might have paid more than one month in advance to
any prior landlord (including the Landlord), except to the extent actually
received by Agent, Lenders or such purchaser; or (e) bound by any amendment or
modification of the Lease, or any consent to any assignment or sublet, made
without Agent's prior written consent if required under the Deed of Trust and
other Loan Documents; or (f) bound by or responsible for any security deposit
not actually received by Agent; or (g) liable for or incur any obligation with
respect to any breach of warranties or representations of any nature under the
Lease or otherwise including without limitation any warranties or
representations respecting use, compliance with zoning, landlord's title,
landlord's authority, habitability and/or fitness for any purpose, or
possession; or (h) liable for consequential damages. The foregoing shall not,
however: (i) relieve Agent, Lenders or such purchaser of the obligation to
remedy or cure any conditions at the Premises the existence of which constitutes
a Landlord default under the Lease and which continue at the time of such
succession or acquisition, or (ii) deprive the Tenant of the right to terminate
the Lease for a breach of Landlord covenant which is not cured as provided for
herein and in the Lease and as a result of which there is a material
interference with Tenant's permitted use and occupation of the Premises or any
permitted business conducted therein.

            5. RIGHTS RESERVED. Nothing herein contained is intended, nor shall
it be construed, to abridge or adversely affect any right or remedy of: (a) the
Landlord under the Lease, or any subsequent Landlord, against the Tenant in the
event of any default by Tenant (beyond any period expressed in the Lease within
which Tenant may cure such default) in the payment of rent or in the performance
or observance of any of the terms, covenants or conditions of the Lease on
Tenant's part to be performed or observed; or (b) the Tenant under the Lease
against the original or any prior Landlord in the event of any default by the
original Landlord to pursue claims against such original or prior Landlord
whether or not such claim is barred against Lender or a subsequent purchaser.

            6. NOTICE AND RIGHT TO CURE. Tenant agrees to provide Agent with a
copy of each notice of default given to Landlord under the Lease, at the same
time as such notice of default is given to the Landlord, and that in the event
of any default by the Landlord under the Lease, Tenant will take no action to
terminate the Lease (a) if the default is not curable by Lender (so long as the
default does not interfere with Tenant's use and occupation of the Premises), or
(b) if the default is curable by Agent or Lenders, unless the default remains
uncured for a period of thirty (30) days after written notice thereof shall have
been given, postage prepaid, to Landlord at Landlord's address, and to Agent at
the address provided in Section 7 below; provided, however, that if any such
default is such that it reasonably cannot be cured within such thirty (30) day
period, such period shall be extended for such additional period of time (not to
exceed 120 days) as shall be reasonably necessary (including, without
limitation, a reasonable

                                       3
<PAGE>

period of time to obtain possession of the Property and to foreclose the Deed of
Trust, if necessary to effectuate a cure), if Agent gives Tenant written notice
within such thirty (30) day period of Lender's election to undertake the cure of
the default and if curative action (including, without limitation, action to
obtain possession and foreclose) is instituted within such thirty-day period and
is thereafter diligently pursued. Agent and Lenders shall have no obligation to
cure any default under the Lease, except to the extent provided in paragraph 4
above.

            7. NOTICES. Any notice or communication required or permitted
hereunder shall be in writing, and shall be given or delivered: (i) by United
States mail, registered or certified, postage fully prepaid, return receipt
requested, or (ii) by recognized courier service or recognized overnight
delivery service; and in any event addressed to the party for which it is
intended at its address set forth below:

                  To Agent:              Fleet National Bank
                                         111 Westminster Street, Suite 800
                                         Providence, RI  02903
                                         Attention:  Commercial Real Estate/Loan
                                         Administration Manager

                  To Tenant:             _______________________________
                                         _______________________________
                                         _______________________________

or such other address as such party may have previously specified by notice
given or delivered in accordance with the foregoing. Any such notice shall be
deemed to have been given and received on the date delivered or tendered for
delivery during normal business hours as herein provided.

            8. NO ORAL CHANGE. This Agreement may not be modified orally or in
any manner than by an agreement in writing signed by the parties hereto or their
respective successors in interest.

            9. SUCCESSORS AND ASSIGNS. This Agreement shall inure to the benefit
of and be binding upon the parties hereto, their respective heirs, personal
representatives, successors and assigns, and any purchaser or purchasers at
foreclosure of the Property or any portion thereof, and their respective heirs,
personal representatives, successors and assigns.

            10. PAYMENT OF RENT TO AGENT. Tenant acknowledges that it has notice
that the Lease and the rent and all sums due thereunder have been assigned to
Agent as part of the security for the Obligations secured by the Deed of Trust
Documents. In the event Agent notifies Tenant of a default under the Loan and
demands that Tenant pay its rent and all other sums due under the Lease to
Agent, Tenant agrees that it will honor such demand and pay its rent and all
other sums due under the Lease to Agent, or Agent's designated agent, until
otherwise notified in writing by Agent. Borrower unconditionally authorizes and
directs Tenant to make rental payments directly to Lender following receipt of
such notice and further agrees that Tenant may rely upon such notice without any
obligation to further inquire as to whether or not any default exists under the
Deed of Trust Documents, and that Borrower shall have no right or claim against
Tenant for or by reason of any payments of rent or other charges made by Tenant
to Agent following receipt of such notice.

            11. NO AMENDMENT OR CANCELLATION OF LEASE. So long as the Deed of
Trust remains undischarged of record and except as provided herein to the
contrary (including paragraph 6 hereof), Tenant shall not amend, modify, cancel
or terminate the Lease, or consent to an amendment, modification, cancellation
or termination of the Lease, or agree to subordinate the Lease to any other

                                       4
<PAGE>

Deed of Trust, without Agent's prior written consent in each instance if
required under the Deed of Trust or other Loan Documents.

            12. CAPTIONS. Captions and headings of sections are not parts of
this Agreement and shall not be deemed to affect the meaning or construction of
any of the provisions of this Agreement.

            13. COUNTERPARTS. This Agreement may be executed in several
counterparts each of which when executed and delivered is an original, but all
of which together shall constitute one instrument.

            14. GOVERNING LAW. This Agreement shall be governed by and construed
in accordance with the laws of the State of California.

            15. PARTIES BOUND. The provisions of this Agreement shall be binding
upon and inure to the benefit of Tenant, Agent, Lenders and Borrower and their
respective successors and assigns; provided, however, reference to successors
and assigns of Tenant shall not constitute a consent by Landlord or Borrower to
an assignment or sublet by Tenant, but has reference only to those instances in
which such consent is not required pursuant to the Lease or for which such
consent has been given.
