                                    for either or both Landlord Delays or Tenant

                                    pursuant to this Section 2, then the Base

                                         (iii) If neither party appoints an
                                    appraiser within the time period set forth

                                          (iv) If the two (2) appraisers are so
                                    appointed by the parties, they shall meet

                                    determine the Fair Market Rent. If they are

                                    appraiser and of the third appraiser's fees.
                                    The third appraiser, however selected, shall
                                    be a person who has not previously acted in
                                    any capacity for either party.

                                    of the appraisers shall appraise and
                                    detemine the Fair Market Rent. If a

                                    total divided by three, The resulting
                                    quotient shall be the Fair Market Rent.

                                          (vi) If, however, the low appraisal
                                    or the high appraisal are more than ten
                                    percent (10%) lower or higher than the
                                    middle appraisal, the low appraisal or the
                                    high appraisal shall be disregarded, If only
                                    one appraisal is disregarded, the remaining
                                    two appraisals shall be added together and
                                    their total divided by two. The resulting
                                    quotient shall be the Fair Market Rent. If
                                    two appraisals are disregarded, the
                                    remaining appraisal shall be the Fair Market
                                    Rent.

                                    of the Premises causes any increase in the
                                    premium for such insurance policies, and
                                    such conduct is otherwise permitted by
                                    Landlord, then Tenant shall reimburse
                                    Landlord for any such increase. Tenant, at

                                    that such coverage shall be primary and that
                                    any insurance maintained by Landlord shall
                                    be excess insurance only. Such coverage
                                    shall also contain endorsements: (i)
                                    deleting any employee exclusion on personal
                                    injury coverage; (ii) including employees as
                                    additional insureds; and (iii) providing for
                                    coverage of employer's automobile

                                    shall provide for severability of interests;
                                    shall provide that an act or omission of
                                    one of the named insureds shall not reduce
                                    or avoid coverage to the other named
                                    insureds; and shall afford coverage for all
                                    claims based on acts, omissions injury and

                                    the onset of which occurred or arose) in
                                    whole or in part during the policy period
                                    and shall be written as primary policies,
                                    not excess or contributing with or secondary
                                    to any other insurance as may be available
                                    to the additional insureds. Said coverage
                                    shall be written on an "occurrence" basis,
                                    if available. If a "claims made" policy is
                                    ever used, the policy must be endorsed so
                                    that Landlord is given the right to purchase
                                    "tail" coverage should Tenant for any reason
                                    not do so or if the policy is to be canceled
                                    for nonpayment of premium.

                                    (3) GENERAL INSURANCE REQUIREMENTS. All
                                    coverages described in this Paragraph 8.B.
                                    shall be endorsed to provide Landlord with
                                    thirty (30) days' notice of cancellation,
                                    material change in terms or reduction,

                                    of insurance which Tenant is required to
                                    carry under this Paragraph 8.B. is, in

                                    less than the amount or type of insurance
                                    coverage typically carried by owners or
                                    tenants of properties located in the general

                                    reasonably increase the amount or change the
                                    types of insurance coverage required under
                                    the Paragraph 8.B. All insurance policies

                                    of Tenant, and the reasonable cost thereof

                                    to terminate this Lease as a result of such
                                    Landlord default. Notwithstanding the
                                    foregoing, the subordination of Tenant's
                                    rights and interests under this Lease to any
                                    mortgage or deed of trust shall be
                                    contingent upon Tenant's having received
                                    from any such ground lessor, mortgagee or
                                    beneficiary of any deed of trust a written
                                    recognition agreement in form reasonably
                                    satisfactory to Tenant providing that
                                    Tenant's rights and interest shall not be
                                    disturbed in the event of any foreclosure of
                                    any such lease, mortgage or deed of trust
                                    and confirming that Tenant shall receive
                                    all of the rights and services provided for
                                    under this Lease. Landlord's failure to
                                    obtain such an agreement shall not be a
                                    default by Landlord pursuant to the terms of
                                    this Lease. Further, Tenant shall have no
                                    obligation to attorn to any
                                    successor in interest or ground lessor, nor
                                    to execute any instruments evidencing
                                    attornment, unless the successor in interest
                                    or ground lessor assumes Landlord's
                                    obligations under this Lease in writing.

                                    B. ATTORNMENT AND NON-DISTURBANCE. Tenant
                                    shall attorn to and recognize as Tenant's
                                    landlord under this lease any superior
                                    lessor, superior mortgagee or other
                                    purchaser or person taking title to the
                                    Building by reason of the termination of any
                                    superior lease or the foreclosure of any
                                    superior mortgage or deed of trust and
                                    Tenant shall, upon demand, execute any
                                    documents reasonably requested by any such
                                    person to evidence the attornment described
                                    in this Section 15.B. Notwithstanding
                                    anything in this Section 15, Tenant's
                                    occupancy of the Premises during the term of
                                    this Lease shall not be disturbed so long as
                                    there is no uncured event of default by
                                    Tenant hereunder.

                                    C. MORTGAGE PROTECTION. Tenant agrees to
                                    give any holder of any mortgage and any
                                    ground lessor, by registered or certified
                                    mail, a copy of any notice of default served
                                    upon the Landlord by Tenant provided that

                                       17




                                    prior to such notice Tenant has been
                                    notified in writing of the address of such
                                    mortgage holder or ground lessor (hereafter
                                    the "Notified Party"). Tenant further agrees
                                    that if Landlord shall have failed to cure
                                    such default within twenty (20) days after
                                    such notice to Landlord (or if such default
                                    cannot be cured or corrected within that
                                    time, then such additional time as may be
                                    necessary if Landlord has commenced within
                                    such twenty (20) days and is diligently
                                    pursuing the remedies or steps necessary to
                                    cure or correct such default), then the
                                    Notified Party shall have an additional
                                    thirty (30) days within which to cure or
                                    correct such default (or if such default
                                    cannot be cured or corrected within that
                                    time, then such additional time as may be
                                    necessary if the Notified Party has
                                    commenced within such thirty (30) days and
                                    is diligently pursuing the remedies or steps
                                    necessary to cure or correct such default).
                                    Until the time allowed, as aforesaid, for
                                    the Notified Party to cure such default has
                                    expired without cure, Tenant shall have no
                                    right to, and shall not terminate this Lease
                                    on account of Landlord's default.

FINANCIAL                  16.      At the request of Landlord, but not more
STATEMENTS                          than twice per annum, Tenant shall provide
                                    to Landlord Tenant's current publicly
                                    available financial statement or such other
                                    publicly available information discussing
                                    financial worth of Tenant as may be
                                    reasonably requested by Landlord, which
                                    Landlord shall use solely for purposes of
                                    this Lease and in connection with the
                                    ownership, management and disposition of the
                                    Building and keep confidential, provided
                                    that Landlord may disclose such statements
                                    to Landlord's lenders, potential purchasers
                                    of the Building and any professionals hired
                                    or engaged by Landlord in connection
                                    therewith.

ESTOPPEL                   17.      Tenant agrees from time to time, within ten
CERTIFICATE                         (10) business days after request of
                                    Landlord, to deliver to Landlord, or
                                    Landlord's designee, an estoppel certificate
                                    stating that this Lease is in full force and
                                    effect, the date to which Rent has been
                                    paid, the unexpired portion of this Lease,
                                    and such other matters pertaining to this
                                    Lease as may be reasonably requested by
                                    Landlord. Failure by Tenant to execute and
                                    deliver such certificate shall constitute an
                                    acceptance of the Premises and
                                    acknowledgment by Tenant that the statements
                                    included are true and correct without
                                    exception. Landlord and Tenant intend that
                                    any statement delivered pursuant to this
                                    paragraph may be relied upon by any
                                    mortgagee, beneficiary, purchaser or
                                    prospective purchaser of the Building or any
                                    interest therein.

SECURITY                   18.      Tenant agrees to deposit with Landlord upon
DEPOSIT                             execution of this Lease a Security Deposit
                                    as stated in the Basic Lease Information,
                                    which sum shall be held by Landlord,
                                    without obligation for interest as
                                    security for the performance of Tenant's
                                    covenants and obligations under this
                                    Lease. the Security Deposit is not an
                                    advance rental deposit or a measure of
                                    damages incurred by Landlord in case of
                                    Tenant's default. Landlord may, from time
                                    to time, without prejudice to any other
                                    remedy provided herein or provided by
                                    law, use such fund to the extent
                                    necessary to make good any arrears of
                                    Rent or other payments due to Landlord
                                    hereunder, and any other damage, injury,
                                    expense or liability caused by such event
                                    of default, and Tenant shall pay' to
                                    Landlord, on demand, the amount so
                                    applied in order to restore the Security
                                    Deposit to its original amount. Although
                                    the Security Deposit shall be deemed the
                                    property of Landlord, any remaining
                                    balance of such deposit shall be returned
                                    by Landlord to Tenant at such time after
                                    termination of this Lease that all of
                                    Tenant's obligations under this Lease
                                    have been fulfilled. Landlord may use and
                                    commingle the Security Deposit with other
                                    funds of

                                       18




                                    Landlord.

TENANT'S                   19.      The liability of Landlord to Tenant for any
REMEDIES                            default by Landlord under the terms of this
                                    Lease are not personal obligations of the
                                    individual or other partners, directors,
                                    officers and shareholders of Landlord, and
                                    Tenant agrees to look solely to Landlord's
                                    interest in the Building for the recovery of
                                    any amount from Landlord, and shall not look
                                    to other assets of Landlord nor seek
                                    recourse against the assets of the
                                    individual or other partners, directors,
                                    officers and shareholders of Landlord.

                                    of the assignment or sublease. Landlord
                                    shall then have a period of ten (10)
                                    business days following receipt of such
                                    notice to either: (1) terminate this Lease
                                    as to the space so affected as of the date

                                    limiting the other instances in which it may
                                    be reasonable for Landlord to withhold
                                    Landlord's consent to an assignment or
                                    subletting, Landlord and Tenant acknowledge
                                    that it shall be reasonable for Landlord to
                                    withhold Landlord's consent in the following
                                    instances: The use of the Premises by such
                                    proposed assignee or subtenant would not be
                                    a permitted use; the proposed assignee or
                                    subtenant is not of sound financial
                                    condition; the proposed assignee or
                                    subtenant is a governmental agency; the
                                    proposed assignee or subtenant does not have
                                    a good reputation as a tenant of property;
                                    the proposed assignee or subtenant is a
                                    person with whom Landlord is negotiating to
                                    lease space in the Building; the assignment
                                    or subletting would entail any alterations
                                    which would lessen the value of the
                                    leasehold improvements in the Premises; or
                                    if Tenant is in default of any obligation of
                                    Tenant under this Lease, or Tenant has

                                    consent. Tenant shall pay promptly upon
                                    billing any and all reasonable attorneys'
                                    fees and other costs reasonably incurred by
                                    Landlord for the review or preparation of
                                    any documents in connection with a proposed

                                    is fairly allocable to such portion, as
                                    determined by Landlord, after deduction
                                    of a reasonable brokerage commission
                                    actually paid by Tenant and deduction of

                                       23



                                    (1) TERMINATION. In the event of the
                                    occurrence of any event of default, Landlord
                                    shall have the right to give a written
                                    termination notice to Tenant, and on the
                                    date specified in such notice, Tenant's
                                    right to possession shall terminate, and
                                    this Lease shall terminate unless on or
                                    before such date all arrears of rental and
                                    all other sums payable by Tenant under this
                                    Lease and all costs and expenses incurred by
                                    or on behalf of Landlord hereunder shall
                                    have been paid by Tenant and all other
                                    events of default of this Lease by Tenant at
                                    the time existing shall have been fully
                                    remedied to the satisfaction of Landlord. At
                                    any time after such termination, Landlord
                                    may recover possession of the Premises or
                                    any part thereof and expel and remove
                                    therefrom Tenant and any other person
                                    occupying the same, by any lawful means, and
                                    again repossess and enjoy the Premises
                                    without prejudice to any of the remedies
                                    that Landlord may have under this Lease, or
                                    at law or equity by reason of Tenant's
                                    default or of such termination

                                    (2) CONTINUATION AFTER DEFAULT. Even though
                                    an event of default may have occurred, this
                                    Lease shall continue in effect for so long
                                    as Landlord does not terminate Tenant's
                                    right to possession under Paragraph 25.B.(I)
                                    hereof, and Landlord may enforce all of
                                    Landlord's rights and remedies under this
                                    Lease, including without limitation, the
                                    right to recover Rent as it becomes due,
                                    and Landlord, without terminating this
                                    Lease, may exercise an of the rights and
                                    remedies of a landlord under Section 1951.4
                                    of the Civil Code of the State of California
                                    or any successor code section. Acts of
                                    maintenance, preservation or efforts to
                                    lease the Premises or the appointment of a
                                    receiver upon application of Landlord to
                                    protect Landlord's interest under this Lease
                                    shall not constitute an election to
                                    terminate Tenant's right to possession.

                                    C. DAMAGES AFTER DEFAULT. Should Landlord
                                    terminate this Lease pursuant to the
                                    provisions of Paragraph 25.B.(I) hereof,
                                    Landlord shall have the rights and remedies
                                    of a Landlord provided by Section 1951.2 of
                                    the Civil Code of the State of California or
                                    successor code sections. Upon such
                                    termination, in addition to any other rights
                                    and remedies to which Landlord may be
                                    entitled under applicable law, Landlord
                                    shall be entitled to recover from Tenant:
                                    (1) the worth at the time of award of the
                                    unpaid Rent and other amounts which had been
                                    earned at the time of termination, (2) the
                                    worth at the time of award of the amount by
                                    which the unpaid Rent which would have been
                                    earned after termination until the time of
                                    award exceeds the amount of such Rent loss
                                    that Tenant proves could have been
                                    reasonably avoided; (3) the worth at the
                                    time of award of the amount by which the
                                    unpaid Rent for the balance of the Tenant
                                    after the time of award exceeds the amount
                                    of such Rent loss that the Tenant proves
                                    could be reasonably avoided; and (4) any
                                    other amount necessary to compensate
                                    Landlord for all the detriment proximately
                                    caused by Tenant's failure to perform
                                    Tenant's obligations under this Lease or
                                    which, in the ordinary course of things,
                                    would be likely to result therefrom. The
                                    "worth at the time of award" of the amounts
                                    referred to in (1) and (2) above, shall be
                                    computed at the lesser of the "prime rate,"
                                    as announced from time to time by Wells
                                    Fargo Bank, N.A. (San Francisco), plus five
                                    (5) percentage points, or the maximum
                                    interest rate allowed by law ("Applicable
                                    Interest Rate"). The "worth at the time of
                                    award" of the amount referred to in (3)
                                    above shall be computed by discounting such
                                    amount at the Federal Discount Rate of the
                                    Federal Reserve Bank of San Francisco at the
                                    time of the award.

                                    D. LATE CHARGE. If any installment of Rent
                                    is not paid within five (5) days after
                                    Landlord shall have given Tenant notice of
                                    nonpayment (provided


                                      24




                                    that Landlord shall not be required to
                                    provide such a notice for more than one (1)
                                    default in any twelve (1-2) consecutive
                                    month period), such amount shall bear
                                    interest at the Applicable Interest Rate,
                                    from the date on which said payment was
                                    originally due until the date on which
                                    Landlord shall receive said payment. In
                                    addition, Tenant shall pay Landlord a late
                                    charge equal to three percent (3%) of the
                                    delinquency, to compensate Landlord for the
                                    loss of the use of the amount not paid and
                                    the administrative costs caused by the
                                    delinquency, the parties agreeing that
                                    Landlord's damage by virtue of such
                                    delinquencies would be difficult to compute
                                    and the amount stated herein represents a
                                    reasonable estimate thereof. This provision
                                    shall not relieve Tenant of Tenant's
                                    obligation to pay Rent at the time and in
                                    the manner herein specified.

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

LIENS                      26.      Tenant shall keep the Premises free from
                                    liens arising out of or related to work
                                    performed, materials or supplies diminished
                                    or obligation incurred by Tenant or in
                                    connection with work made, suffered or done
                                    by or on behalf of Tenant in or on the
                                    Premises or Building. In the event that
                                    Tenant shall not, within twenty (20) days
                                    following the imposition of any such lien,
                                    cause the same to be released of record by
                                    payment or posting of a proper bond,
                                    Landlord shall have, in addition to all
                                    other remedies provided herein and by law,
                                    the right, but not the obligation, to cause
                                    the same to be released by such means as
                                    Landlord shall deem proper, including

                                    operate to release Landlord from any
                                    liability upon any of the covenants or

                                    agrees to look solely to the responsibility
                                    of the successor-in-interest of Landlord
                                    under this Lease with respect to the

                                    to remedy any continuing Landlord default,
                                    such as a continuing failure to maintain and
                                    repair.

                                    do so, and without waiving or releasing
                                    Tenant from any obligations of Tenant, make

                                    Tenant's part to be made or performed. All
                                    sums so paid by Landlord and all necessary
                                    incidental costs together with interest
                                    thereon at the Applicable Interest Rate
                                    from the date such payment by Landlord shall
                                    be payable to Landlord on demand, and Tenant
                                    covenants to pay such sums, and Landlord
                                    shall have, in addition to any other right

                                    Basic Operating Building Cost.

WAIVER                     29.      If either Landlord or Tenant waives the
                                    performance of any term, covenant or
                                    condition contained in this Lease, such
                                    waiver shall not be deemed a waiver of any
                                    subsequent breach of the same or any other
                                    term, covenant or condition contained
                                    herein. The acceptance of Rent by Landlord
                                    shall not constitute a waiver of any
                                    preceding breach by Tenant of any term,
                                    covenant or condition of this Lease,
                                    regardless of Landlord's knowledge of such
                                    preceding breach at the time Landlord
                                    accepted such Rent. Failure by Landlord to
                                    enforce any of the terms, covenants or
                                    conditions of this Lease for any length of
                                    time shall not be deemed to waive or to
                                    decrease the right of Landlord to insist
                                    thereafter upon strict performance by
                                    Tenant. Waiver of any term, covenant or
                                    condition contained in this, Lease may only
                                    be made by a written document signed by
                                    Landlord.
