                            Indemnification Agreement
                            -------------------------

          This AGREEMENT, made and entered into as of the 10/th/ day of July,
2001, by and between KAISER VENTURES LLC., a Delaware limited liability company
(the "Company") and _____________________________________ ("Officer").

                              W I T N E S S E T H:
                              - - - - - - - - - -

          WHEREAS, Officer in the course of his current and future service to
the Company may be made a party to a legal action or other proceeding which may
result in personal economic loss to Officer; and

          WHEREAS, the Company desires to retain the current and future services
of Officer and to reimburse Officer for any such personal economic losses of
Officer resulting from the good faith performance of Officer's duties; and

          WHEREAS, the indemnification provisions of the Operating Agreement of
the Company, as it may be amended from time to time, may be subject to reduction
or elimination at any time without the consent of Officer, and Company desires
to provide indemnification to Officer to the fullest extent permitted by law
despite any such change.

          NOW, THEREFORE, in consideration of the services of Officer to the
Company, Company and Officer agree as follows:

          1.     Indemnification.  The Company agrees to indemnify Officer
according to the terms, conditions and procedures of this Agreement and Exhibit
A attached hereto and incorporated herein by this reference from the effective
date hereof in perpetuity. Any Capitalized Terms not defined herein shall be as
defined in Exhibit "A."
           ----------

          2.     Notice; Right to Counsel. Within 30 days after receiving notice
of any claim or threatened claim against Officer by reason of the fact that he
is or was a Officer, officer, employee or agent of the Company or is or was
serving at the request of the Company as a manger, director, officer, employee
or agent of another Person, Officer shall notify the Company in writing. Failure
to so notify the Company shall not relieve the Company form any liability under
this Agreement, except to the extent that the failure to give such notice is
detrimental to the Company. Furthermore, Officer shall have the right to select
his or her own legal counsel in the defense of any such claim or threatened
claim; provided, however, in the event that any other Indemnified Person(s) are
not known to be in any substantially different legal position with respect to
such claim or threatened claim, the Company will reimburse Officer and all such
other Indemnified Persons for the cost of only one counsel, who shall be
reasonably selected by the majority of the Indemnified Persons to be so
represented.

          3.     Amendments to Limited Liability Operating Agreement. Any
amendments to Limited Liability Operating Agreement of the Company ("Operating
Agreement") which reduce or eliminate indemnification rights of persons there
under shall have no effect with respect to this Agreement or the rights granted
hereunder, and thereafter Officer shall continue to have all the rights granted
hereunder, regardless of such amendments to the Operating Agreement [for future
acts as well?]. However, if the Operating Agreement of the Company or the
Delaware Limited Liability Company Act (the "Act") are amended to provide for
greater indemnification

                                       1

<PAGE>

rights or privileges, this Agreement shall not be construed so as to limit
Officer's rights and privileges to the terms hereof, and Officer shall be
entitled to the full benefit of any such additional rights and privileges.
Furthermore, to the extent that the Act or other applicable law now or hereafter
establishes that indemnification cannot be made by the Company according to this
Agreement in any respect, this Agreement shall be interpreted as being
simultaneously amended to provide indemnification hereunder to the fullest
extent permitted by law.

          4.     Successors and Assigns.  This Agreement shall be binding upon
and shall inure to any and all successors, assigns, heirs, estates,
representatives and administrators of the parties hereto.

          5.     No Amendments.  This Agreement may not be amended, modified or
terminated except by the express written consent thereto by both parties hereto.

          6.     Other Agreement.  This Agreement is supplementary to and not
exclusive of other agreements between the Company and Officer, which may exist
now, or in the future to the extent such agreements are not inconsistent
herewith.

          7.     Survival.  The rights of Officer under this Agreement shall
survive and continue in effect after the termination of services to the Company
by Officer, whether by death, retirement or otherwise.

          8.     Severability.  If any provision or application of this
Agreement is held unlawful or unenforceable in any respect, such illegality or
unenforceability shall not affect other provisions or applications which can be
given effect, and this Agreement shall be construed as if the unlawful or
unenforceable provision or application had never been contained herein or
prescribed hereby.

          9.     Governing Law.  This Agreement shall be interpreted and
governed by the laws of the State of Delaware.

          IN WITNESS WHEREOF, the undersigned parties have executed this
Agreement effective as of, notwithstanding the actual date of execution.

                                   -----------

the following terms shall have the meaning specified below.

          1.1    "Board" means the Board of Officers of the Company.

          1.2    "Company" means Kaiser Ventures LLC, a Delaware limited
liability company.

and retainers, court costs, transcript costs, fees of accountants, experts and
witnesses, travel expenses, duplicating costs, printing and binding costs,
telephone charges, postage, delivery, service fees, and all other expenses of
the types customarily incurred in connection with prosecuting, defending,
preparing to prosecute or defend, investigating, or being or preparing to be a
witness or other participant in a Proceeding.

          1.4    "Indemnified Person" means a Officer, officer or employee of
the Company.

          1.5    "Liabilities" means (i) any Expenses and (ii) any other
judgments, fines, penalties, ERISA excise taxes, and amounts paid in settlement
of any claim, in connection with any Proceeding.

          1.6    "Person or "person" means an individual, general partnership,

estate investment trust association or any other entity.

          1.7    "Proceeding" means any action, suit, arbitration, alternative
dispute resolution mechanism, investigation, administrative hearing or other
proceeding, whether civil, criminal, administrative or investigative in nature,
except a proceeding initiated by a Person pursuant to Section 2.

2.        Indemnification of Indemnified Persons.

          2.1    General.  The Company shall indemnify any Indemnified Person
against all Liabilities that he or she has actually and reasonably incurred or
paid in connection with a Proceeding described in Section 3.1 if he or she (i)
meets the standard of conduct described in Section 2.2, and (ii) properly makes
application for indemnification as described in Section 3. The Board may, in its
sole discretion, indemnify any other Person, who is not an Indemnified Person,
against all Liabilities that such Person has actually and reasonably incurred or
paid in connection with a Proceeding on terms determined by the Board at that
time, which terms may be less favorable to the indemnitee than those described
in the mandatory indemnification provisions below.

          2.2    Standard of Conduct.  The Company shall only indemnify a Person
if, in connection with his or her actions which are the subject of the
Proceeding, (i) he or she shall have acted in good faith and in a manner he or
she reasonably believed was consistent with the best interests of the Company,
and (ii) if the Proceeding is a criminal Proceeding, he or she had no reasonable
cause to believe that his or her conduct was unlawful. The Company shall not
indemnify any Person if that Person's action is finally adjudged to have been
willful misconduct, knowingly fraudulent or deliberately dishonest.

                                       3

<PAGE>

          2.3    Burden of Proof.  An Indemnified Person shall be conclusively
presumed to have met these standards of conduct unless a court of competent
jurisdiction finally determines to the contrary. The Company shall bear the
burden of proof of establishing by clear and convincing evidence that such
Indemnified Person failed to meet the applicable standard of conduct. The
termination of any Proceeding, whether by judgment, order, settlement or
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that an Indemnified Person did not meet the
applicable standard of conduct.

          2.4    Payment of Expenses.  Expenses incurred by an Indemnified
Person in connection with a Proceeding shall be paid by the Company in advance
of the final disposition of the Proceeding upon receipt of his or her written
undertaking to repay any advances if it is ultimately determined that he or she
is not entitled to be indemnified by the Company as authorized in this
Agreement.

3.        Application for Indemnification.

          3.1    Proceedings Covered.  Any Person may apply for indemnification
if he or she was or is a party to, or is threatened to be made a party to, or
otherwise becomes involved in, any Proceeding (including any Proceeding by or in
the right of the Company), in the case of an Indemnified Person, because of his
or her status as such, and in the case of any other Person, because he or she is
or was an agent of the Company. Except with the consent of the Board or as
provided in Section 3.3 with respect to a Proceeding brought to establish or
enforce a right to indemnification under this Agreement, the Company will not be
required to indemnify any Person, including any Indemnified Person, with respect
to a Proceeding or portion of a Proceeding which that Person initiated or
brought voluntarily and not by way of defense.

          3.2    Content of Application.  The application for indemnification
shall be in writing, shall state the basis for the claim for indemnification,
and shall include a copy of any notice or other document served on or otherwise
received by the Person making the application. The application shall also
contain a statement that the Person making the application has met the
applicable standard of conduct described in Section 2.2 and will comply with the
provisions of this Agreement.

          3.3    Determination of Right to Indemnification.  The determination
of whether or not to indemnify an Indemnified Person in connection with any
Proceeding shall be made by any of the following means:

                 (i)     by the Officers of the Company, by a majority vote of a
quorum consisting of Officers who are not parties to the Proceeding; or

                 (ii)    if no such quorum is obtainable or, even if obtainable,
a quorum of the disinterested Officers of the Company so directs, by independent
legal counsel in a written opinion; or

                 (iii)   by the members of the Company, by a vote of a Majority
(as defined in the Operating Agreement) of those members, whether or not
constituting a quorum, who are not parties to the Proceeding.

4.        Enforcement of Indemnification Right. The right of an Indemnified
Person to indemnification or an advance of Expenses as provided by this
Agreement shall be enforceable in

                                       4

<PAGE>

any court of competent jurisdiction. Any determination by the Officers of the
Company, members of the Company, or the Company's independent legal counsel that
indemnification or an advance is improper in the circumstances, or any failure
to make such a determination, shall not be a defense to the action or create a
presumption that the relevant standard of conduct has not been met. An
Indemnified Person's Expenses incurred in connection with any Proceeding brought
to enforce his or her right to indemnification shall also be indemnified by the
Company, regardless of the outcome, unless a court of competent jurisdiction
finally determines that each of the material assertions made by such Indemnified
Person in the Proceeding was not made in good faith or were frivolous.

5.        Limitations on Indemnification.  No payments pursuant to this
Agreement shall be made by the Company if a court of competent jurisdiction
finally determines that any indemnification or advance of Expenses hereunder is
unlawful.

6.        Insurance.

          6.1    General.  The Company shall have the power to purchase and
maintain insurance or other financial arrangement on behalf of any Person who is
or was a Company Person or an agent of the Company against any liability
asserted against such Person and incurred by such Person in any such capacity,
or arising out of such Person's status as a Company Person or agent, whether or
not the Company would have the power to indemnify such Person against such
liability under the provisions of this Agreement.

          6.2    Company Right to Reimbursement.  If a Person receives payment
from any insurance carrier, or from the plaintiff in any action against such
Person, with respect to indemnified amounts after payment of such indemnified
amounts have been made by the Company pursuant to this Agreement, such Person
shall reimburse the Company for the amount by which the sum of (i) the payment
by the insurance carrier or plaintiff and (ii) all payments by the Company to
such Person, exceeds such indemnified amounts. In making this calculation, any
insurance proceeds that are required to be reimbursed to the insurance carrier
under the terms of its insurance policy shall not be counted as payments to such
Person. In addition, upon payment of indemnified amounts under the terms and
conditions of this Agreement, the Company shall be subrogated to such Person's
rights against any insurance carrier with respect to such indemnified amounts
(to the extent permitted under such insurance policies). Such right of
subrogation shall be terminated upon receipt by the Company of the amount to be
reimbursed by such Person pursuant to the second sentence of this Section 6.3.

7.        Other Terms of Indemnification.

          7.1    Timing of Payments.  Any indemnification or advance shall be
made promptly, but in any case no later than thirty (30) days after the Company
has received a written request for payment from the Indemnified Person seeking
indemnification, unless the Company has determined that he or she is not
entitled to indemnification hereunder.

          7.2    Partial Indemnification.  If an Indemnified Person is entitled
under any provision of this Agreement to indemnification for a portion of his or
her Liabilities, but not for the total amount, the Company shall nevertheless
indemnify him or her for the portion of such Liabilities to which he or she is
entitled, except that no indemnification shall be given for Expenses in
connection with a Proceeding brought by the Company if he or she is found liable
on any portion of the claims in such Proceeding.

                                       5

<PAGE>

          7.3    Indemnity Not Exclusive.  The indemnification and advancement
of Expenses provided by this Agreement shall not be exclusive of any other
rights to which any Indemnified Person seeking indemnification or advancement of
Expenses may be entitled under any agreement, vote of Members, determination of
the Board, or otherwise, both as to action in such Indemnified Person's capacity
as such and as to action in another capacity while serving as an Indemnified
Person. Any repeal or modification hereof or thereof shall not affect any such
rights then existing.

          7.4    Heirs, Executors and Administrators.  The indemnification and
advancement of Expenses provided by this Agreement shall, continue as to an
Indemnified Person who is no longer acting in such capacity, and shall inure to
the benefit of his or her heirs, executors and administrators, unless otherwise
provided when authorized or ratified.

fixtures, and improvements therein and keep all of the foregoing clean and in
good order and operating condition ordinary wear and tear and damage thereto by
fire or other casualty excepted. Tenant hereby waives all rights under
California Civil Code Section 1941 and all rights to make repairs at the expense
of Landlord or in lieu thereof to vacate the Premises as provided by California
Civil Code Section 1942 or any other law, statute, or ordinance now or hereafter
in effect. Tenant shall, at the end of the term of this Lease, surrender to
Landlord the Premises and all alterations, additions, and improvements thereto
in the same condition as when received, ordinary wear and tear and damage
thereto by fire or other casualty excepted.

                       ARTICLE 10 - Damage or Destruction

          10.1 If the Building or the Premises, or any part thereof, is damaged
by fire or other casualty before the Commencement Date or during the term of
this Lease, and this Lease is not terminated pursuant to Section 10.2 hereof,
Landlord shall repair such damage and restore the Building and the Premises to
substantially the same condition in which the Building and the Premises existed
before the occurrence of such fire or other casualty and this Lease shall,
subject to this Section 10.1, remain in full force and effect. If such fire or
other casualty damages the Premises or common areas of the Building necessary
for Tenant's use and occupancy of the Premises and if such damage is not the
result of the negligence or willful misconduct of Tenant or Tenant's agents,
employees, contractors, licensees, or invitees, then during the period the
Premises are rendered unusable by such damage, Tenant shall be entitled to a
reduction in Base Rent in the proportion that the area of the Premises rendered
unusable by such damage bears to the total area of the Premises. Landlord shall
not be obligated to repair any damage to, or to make any replacement of, any
movable furniture, equipment, trade fixtures, or personal property in the
Premises. Tenant shall, at Tenant's sole cost and expense, repair and replace
all such movable furniture, equipment, trade fixtures, and personal property.
Such repair and replacement by Tenant shall be done in accordance with Article 8
hereof. Tenant hereby waives California Civil Code Sections 1932(2) and 1933(4)
providing for termination of hiring upon destruction of the thing hired.

          10.2 If the Building or the Premises, or any part thereof, is damaged
by fire or other casualty before the Commencement Date or during the term of
this Lease and (a) such fire or other casualty occurs during the last twelve
(12) months of the term of this Lease and the repair and restoration work to be
performed by Landlord in accordance with Section 10.1 hereof cannot, as
reasonably estimated by Landlord, be completed within two (2) months after the
occurrence of such fire or other casualty, or (b) the insurance proceeds
received by Landlord in respect of such damage are not adequate to pay the
entire cost, as reasonably estimated by Landlord, of the repair and restoration
work to be performed by Landlord in accordance with Section 10.1 hereof, or (c)
the repair and restoration work to be performed by Landlord in accordance with
Section 10.1 hereof cannot, as reasonably estimated by Landlord, be completed
within six (6) months after the occurrence of such fire or other casualty, then,
in any such event, Landlord shall have the right, by giving written notice to
Tenant within sixty (60) days after the occurrence of such fire or other
casualty, to terminate this Lease as of the date of such notice. If

11 - OFFICE LEASE

<PAGE>

Landlord does not exercise the right to terminate this Lease in accordance with
this Section 10.2. Landlord shall repair such damage and restore the Building
and the Premises in accordance with Section 10.1 hereof and this Lease shall,
subject to Section 10.1 hereof, remain in full force and effect. A total
destruction of the Building shall automatically terminate this Lease effective
as of the date of such total destruction.

                             ARTICLE 11 - Insurance

          11.1 Tenant hereby waives all claims against Landlord for damage to or
loss or theft of any property or for any bodily or personal injury, illness, or
death of any person in, on, or about the Premises or the Building arising at any
time and from any cause whatsoever other than by reason of the negligence or
willful misconduct of Landlord. Tenant shall indemnify and defend Landlord
against and hold Landlord harmless from all claims, demands, liabilities,
damages, losses, costs and expenses, including, without limitation, reasonable
attorneys' fees, for any damage to any property (including property of employees
and invitees of Tenant) or for any bodily or personal injury, illness, or death
of any person (including employees and invitees of Tenant) occurring in or on
the Premises or any part thereof arising at any time and from any cause
whatsoever other than by reason of the negligence or willful misconduct of
Landlord or occurring in, on, or about any part of the Building other than the
Premises when such damage, bodily or personal injury, illness, or death is
caused by any act or omission of Tenant or its agents, employees, contractors,
invitees, or licensees. This Section 1l .1 shall survive the termination of this
Lease with respect to any damage, bodily or personal injury, illness, or death
occurring prior to such termination.

          11.2 Landlord's Insurance. Landlord shall secure and maintain:
               --------------------

          (a) All risk property insurance on the Building. Landlord shall not be
              -------------------------------------------
     obligated to insure any furniture, equipment, trade fixtures, machinery,
     goods, or supplies which Tenant may keep or maintain in the Premises or any
     alteration, addition, or improvement which Tenant may make upon the
     Premises. In addition, Landlord shall secure and maintain rental income
     insurance. Landlord may elect to self-insure for the coverages required
     under this section. If the annual cost to Landlord for such property or
     rental income insurance exceeds the standard rates because of the nature of
     Tenant's operations, Tenant shall, upon receipt of appropriate invoices,
     reimburse Landlord for such increased cost.

          (b) Commercial general liability insurance. Such insurance shall be in
              --------------------------------------
     addition to, and not in lieu of, insurance required to be maintained by
     Tenant. Landlord may elect to self-insure for this coverage. Tenant shall
     not be named as an additional insured on any policy of liability insurance
     maintained by Landlord.

12 - OFFICE LEASE

          11.3 Tenant's Insurance. Tenant shall secure and maintain, at Tenant's
               ------------------
expense:

              ---------------------------
     personal property in the Premises, and on any alterations, additions. or
     improvements made by Tenant upon the Premises all for the full replacement
     cost thereof. Tenant shall use the proceeds from such insurance for the
     replacement of fixtures and personal property and for the restoration of
     Tenant's improvements, alterations, and additions to the Premises. Landlord
     shall be named as loss payee as respects alterations, additions, or
     improvements.

          (b) Workers compensation and employers liability insurance. The
              ------------------------------------------------------
     employers liability insurance shall afford limits not less than $500,000
     per accident, $500,000 per employee for bodily injury by disease, and
     $500,000 policy limit for bodily injury by disease. Such insurance shall
     comply with Tenant's obligations to its employees under the law in the
     state in which the Premises are located.

          (c) Commercial general liability insurance which insures against
              ----------------------------

     Medical Payments                                                 5,000

          Any general aggregate limit shall apply on a per-location basis. Such
     insurance shall name Landlord, Landlord's agent and advisor, Landlord's
     property manager, including the trustees, officers, directors, agents, and
     employees of each of the foregoing entities ("Landlord's Representatives"),

     "any auto." A minimum of a $1,000,000 combined single limit per accident
     shall apply.

13 - OFFICE LEASE

<PAGE>

          (e) Umbrella excess liability insurance, on an occurrence basis, that
              -----------------------------------
     applies excess of required commercial general liability, business auto
     liability, and employers liability policies, which insures against bodily
     injury, property damage, personal injury and advertising injury claims with
     the following minimum limits:

     Each Occurrence                                             $2,000,000

     trustees, officers, directors, agents, and employees; Landlord's and
     Landlord's Representatives as additional insureds.

          11.4 General insurance requirements. All policies required to be
               ------------------------------
carried by Tenant hereunder shall be issued by and binding upon an insurance
company licensed to do business in the state in which the property is located
with a rating of at least "A-" "VIII" or better as set forth in the most current
issue of Best's Insurance reports, unless otherwise approved by Landlord. Tenant
shall not do or permit anything to be done that would invalidate the insurance
policies required. Liability insurance maintained by Tenant shall be primary
coverage without right of contribution by any similar insurance that may be
maintained by Landlord. Updated certificates of insurance, acceptable to
Landlord, evidencing the existence and amount of each insurance policy required
hereunder shall be delivered to Landlord prior to the Commencement Date and ten
(10) days prior to each renewal date. Certificates of insurance shall include an
endorsement for each policy showing that Landlord; its trustees, officers,
directors, agents, and employees; Landlord's mortgagees and Landlord's
Representatives are included as additional insureds on liability policies and
that Landlord is loss payee for property insurance. Further, the certificates
must include an endorsement for each policy whereby the insurer agrees not to
cancel the policy without at least thirty (30) days' prior written notice to
Landlord and Landlord's Representatives.

          11.5 Tenant shall not do or permit to be done anything which will
invalidate or increase the cost of any fire, extended coverage or any other
insurance policy covering the Building and/or property located therein. Tenant
shall promptly upon demand reimburse Landlord for any additional premium charged
for such policy by reason of Tenant's failure to comply with the provisions of
this section.

          11.6 In the event that Tenant fails to provide evidence of insurance
required to be provided by Tenant hereunder, prior to the Commencement Date and
thereafter during the Term, within ten (10) days following Landlord's request
thereof, and thirty (30) days prior to the expiration date of any such coverage,
Landlord shall be authorized (but not required) to procure such coverage in the
amount stated with all costs thereof to be chargeable to Tenant and payable upon
written invoice thereof.

14 - OFFICE LEASE

<PAGE>

          11.7 The limits of insurance required by this Lease, or as carried by
Tenant, shall not limit the liability of Tenant or relieve Tenant of any
obligation thereunder, except to the extent provided for under Section 11.8
below. Any deductibles selected by Tenant shall be the sole responsibility of
Tenant. Landlord may, in its sole discretion, change the insurance policy limits
and forms which are required to be provided by Tenant. Such changes will be made
to conform with common insurance requirements for similar properties in similar
geographic locations. Landlord will not change required insurance limits or form
more often than once per calendar year.

          11.8 Anything in this Lease to the contrary notwithstanding, Landlord
and Tenant each waives all rights of recovery, claim, action, or cause of action
against the other, its agents (including partners, both general and limited),
trustees, officers, directors, employees, for any loss or damage that may occur
to the Premises, or any improvements thereto, or the Building or any personal
property of such party therein, by reason of any peril required to be insured
against under this lease, regardless of cause of origin, including negligence of
the other party. Tenant and Landlord covenants that, to the fullest extend
permitted by law, no insurer shall hold any right of subrogation against the
other. Tenant shall advise its insurers of the foregoing and such waiver shall
be permitted under any policies maintained by Tenant pursuant to this Article
11.

                ARTICLE 12 - Compliance With Legal Requirements

          12.1 Tenant shall, at its sole cost and expense, promptly comply with
all laws, ordinances, rules, regulations, orders, and other requirements of any
government or public authority now in force or which may hereafter be in force,
with the requirements of any board of fire underwriters or other similar body
now or hereafter constituted, and with any direction or certificate of occupancy
issued pursuant to any law by any governmental agency or officer, insofar as any
thereof relate to or affect the condition, use, or occupancy of the Premises or
the operation, use, or maintenance of any equipment, fixtures, or improvements
in the Premises, excluding requirements of structural changes not related to or
affected by Tenant's acts or use of the Premises or by improvements made by or
for Tenant.

                     ARTICLE 13 - Assignment and Subletting

          13.1 Tenant shall not, directly or indirectly, without the prior
written consent of Landlord, which consent shall not be unreasonably withheld,
assign this Lease or any interest herein or sublease the Premises or any part
thereof, or permit the use or occupancy of the Premises by any person other than
Tenant. Tenant shall not, directly or indirectly, without the prior written
consent of Landlord, pledge, mortgage, or hypothecate this Lease or any interest
herein. This Lease shall not, nor shall any interest herein, be assignable as to
the interest of Tenant involuntarily or by operation of law without the prior
written consent of Landlord. Any of the foregoing acts without such prior
written consent of Landlord shall be void and shall, at the option of Landlord,
constitute a default that entitles Landlord to terminate this Lease.

15 - OFFICE LEASE

<PAGE>

Without limiting or excluding other reasons for withholding Landlord's consent,
Landlord shall have the right to withhold consent if the proposed assignee or
subtenant or the use of the Premises to be made by the proposed assignee or
subtenant is not consistent with the character and nature of other tenants and
uses in the Building or is prohibited by this Lease or if it is not demonstrated
to the satisfaction of Landlord that the proposed assignee or subtenant has good
business and moral character and reputation and is financially able to perform
all of the obligations of Tenant under this Lease. Tenant agrees that the
instrument by which any assignment or sublease to which Landlord consents is
accomplished shall expressly provide that the assignee or subtenant will perform
all the covenants to be performed by Tenant under this Lease as and when
performance is due after the effective date of the assignment or sublease and
that Landlord will have the right to enforce such covenants directly against
such assignee or subtenant. Any purported assignment or sublease without an
instrument containing the foregoing provisions shall be void. Tenant shall in
all cases remain liable and responsible for the performance by any assignee or
subtenant of all such covenants.

          13.2 If Tenant wishes to assign this Lease or sublease all or any part
of the Premises, Tenant shall give written notice to Landlord identifying the
intended assignee or subtenant by name and address and specifying all of the
terms of the intended assignment or sublease. Tenant shall give Landlord such
additional information concerning the intended assignee or subtenant or the
intended assignment or sublease as Landlord reasonably requests. For a period of
thirty (30) days after such notice is given by Tenant, Landlord shall have the
right, by giving written notice to Tenant, either (a) to enter into an
assignment of this Lease or a sublease of the Premises, as the case may be, with
Tenant upon the terms set forth in such notice or (b) in the case of an
assignment of this Lease or a sublease of the entire Premises for the balance of
the term of this Lease, to terminate this Lease, which termination shall be
effective as of the date on which the intended assignment or sublease would have
been effective if Landlord had not exercised its termination right. If Landlord
elects to enter into an assignment of this Lease or a sublease of the Premises
or to terminate this Lease, Landlord may enter into a new lease or agreement
covering the Premises or any portion thereof with the intended assignee or
subtenant on such terms as Landlord and such assignee or subtenant agree, or
enter into a new lease or agreement covering the Premises or any portion thereof
with any other person. In such event, Tenant shall not be entitled to any
portion of the profit, if any, which Landlord may realize on account of such new
lease or agreement. If Landlord elects to terminate this Lease, then from and
after the date of such termination, Landlord and Tenant each shall have no
further obligation to the other under this Lease with respect to the Premises
except for matters occurring or obligations arising hereunder prior to the date
of such termination.

          13.3 If Landlord does not exercise its rights under Section 13.2
hereof and consents in writing, Tenant may complete the intended assignment or
sublease subject to the following covenants: (a) the assignment or sublease
shall be on the same terms as set forth in the written notice given by Tenant to
Landlord, (b) no assignment or sublease shall be valid and no assignee or
subtenant shall take possession of the Premises or any part thereof until an
executed duplicate original of such assignment or sublease, in compliance with
Section 13.1 hereof, has

16 - OFFICE LEASE

<PAGE>

been delivered to Landlord, (c) no assignee or subtenant shall have a right
futher to assign or sublease, and (d) all "excess rent" (as hereinafter defined)
derived from such assignment or sublease shall be divided and paid fifty percent
(50%) to Tenant and fifty percent (50%) to Landlord. Landlord's share of such
excess rent shall be deemed to be, and shall be paid by Tenant to Landlord as,
additional rent. Tenant shall pay Landlord's share of such excess rent to
Landlord immediately as and when such excess rent is receivable by Tenant. As
used in this Section 13.3,"excess rent" shall mean the amount by which the
total money and other economic consideration to be paid by the assignee or
subtenant as a result of an assignment or sublease, whether denominated rent or
otherwise, exceeds, in the aggregate, the total amount of rent which Tenant is
obligated to pay to Landlord under this Lease (prorated to reflect the rent
allocable to the portion of the Premises subject to such assignment or
sublease), less the reasonable costs paid by Tenant for additional improvements
installed in the portion of the Premises subject to such assignment or sublease
by Tenant at Tenant's sole cost and expense for the specific assignee or
subtenant in question and reasonable leasing costs (such as brokers' commissions
but excluding carrying costs due to vacancy or any other cause) paid by Tenant
in connection with such assignment or sublease, which costs of additional
improvements and leasing costs shall be amortized without interest over the term
of such assignment or sublease, unless, with respect to such additional
improvements, such additional improvements have a useful life greater than the
term of such assignment or sublease, in which case such additional improvements
shall be amortized without interest over their useful life.

          13.4 No assignment or sublease whatsoever shall release Tenant from
Tenant's obligations and liabilities under this Lease or alter the primary
liability of Tenant to pay the rent and to perform all other obligations to be
performed by Tenant hereunder. The acceptance of rent by Landlord from any other
person shall not be deemed to be a waiver by Landlord of any provision of this
Lease. Consent to one assignment or sublease shall not be deemed consent to any
subsequent assignment or sublease. If any assignee of Tenant or any successor of
Tenant defaults in the performance of any obligation to be performed by Tenant
under this Lease, Landlord may proceed directly against Tenant without the
necessity of exhausting remedies against such assignee or successor. Landlord
may consent to subsequent assignments or subleases or amendments or
modifications to this Lease with assignees of Tenant, without notifying Tenant
or any successor of Tenant and without obtaining any consent thereto from
Tenant, and such action shall not release Tenant from liability under this
Lease.

                       ARTICLE 14 - Rules and Regulations

          14.1 Tenant shall faithfully observe and comply with the rules and
regulations (the "Rules and Regulations") set forth in Exhibit "B" attached
hereto and, after notice thereof, all modifications thereof and additions
thereto from time to time made in writing by Landlord. If there is any conflict,
this Lease shall prevail over the Rules and Regulations and any modifications
thereof or additions thereto. Landlord shall not be responsible to Tenant for
the noncompliance by any other tenant or occupant of the Building with any Rules
and Regulations.

17 - OFFICE LEASE

<PAGE>

                         ARTICLE 15 - Entry by Landlord

          15.1 Landlord may enter the Premises at any time to (a) inspect the
Premises, (b) exhibit the Premises to prospective purchasers, lenders or
tenants, (c) determine whether Tenant is performing all of its obligations
hereunder, (d) supply any service to be provided by Landlord, (e) post notices
of nonresponsibility, and (f) make any repairs to the Premises, or make any
repairs to any adjoining space or utility services, or make any repairs,
alterations or improvements to any other portion of the Building, provided all
such work shall be done as promptly as reasonably practicable and so as to cause
as little interference to Tenant as reasonably practicable. Tenant waives all
claims for damages for any injury or inconvenience to or interference with
Tenant's business, any loss of occupancy or quiet enjoyment of the Premises or
any other loss occasioned by such entry. Landlord shall at all times have and
retain a key with which to unlock all of the doors in, on or about the Premises
(excluding Tenant's vaults, safes, and similar areas designated in writing by
Tenant and approved in writing by Landlord in advance), and Landlord shall have
the right to use any and all means which Landlord may deem proper to open such
doors in an emergency to obtain entry to the Premises. Any entry to the Premises
obtained by Landlord by any of such means shall not under any circumstances be
construed or deemed to be a forcible or unlawful entry into or a detainer of the
Premises or an eviction, actual or constructive, of Tenant from the Premises or
any portion thereof.

                  ARTICLE 16 - Events of Default and Remedies

          16.1 The occurrence of any one or more of the following events ("Event
of Default") shall constitute a breach of this Lease by Tenant:

     (a) Tenant fails to pay any Base Rent or additional monthly rent as and
when such monthly rent becomes due and payable and such failure continues for
more than three (3) days after Landlord gives written notice thereof to Tenant;
provided, however, that after the second such failure in a calendar year, only
the passage of time, but no further notice, shall be required to establish an
Event of Default in the same calendar year; or

     (b) Tenant fails to pay any additional rent or other amount of money or
charge payable by Tenant hereunder as and when such additional rent or amount or
charge becomes due and payable and such failure continues for more than ten (10)
days after Landlord gives written notice thereof to Tenant; provided, however,
that after the second such failure in a calendar year, only the passage of time,
but no further notice, shall be required to establish an Event of Default in the
same calendar year; or

     (c) Tenant fails to perform or observe any other agreement, covenant or
condition of this Lease to be performed or observed by Tenant as and when
performance or observance is due and such failure continues for more than ten
(10) days after Landlord gives written notice thereof to Tenant; provided,
however, that if, by the nature of such agreement, covenant, or condition, such
failure cannot reasonably be cured within such period of ten (10) days, an Event
of Default

18 - OFFICE LEASE

<PAGE>

shall not exist as long as Tenant commences with due diligence and dispatch the
curing of such failure within such period of ten (10) days and, having so
commenced, thereafter prosecutes with diligence and dispatch and completes the
curing of such failure; or

     (d) Tenant (i) is generally not paying its debts as they become due, (ii)
files, or consents by answer or otherwise to the filing against it of, a
petition for relief or reorganization or arrangement or any other petition in
bankruptcy or liquidation or to take advantage of any bankruptcy, insolvency, or
other debtors' relief law of any jurisdiction, (iii) makes an assignment for the
benefit of its creditors, (iv) consents to the appointment of a custodian,
receiver, trustee, or other officer with similar powers of Tenant or of any
substantial part of Tenant's property, or (v) takes action for the purpose of
any of the foregoing; or

     (e) With consent by Tenant, a court or governmental authority enters an
order, and such order is not vacated within thirty (30) days, (i) appointing a
custodian, receiver, trustee, or other officer with similar powers with respect
to Tenant or with respect to any substantial part of Tenant's property, or (ii)
constituting an order for relief or approving a petition for relief or
reorganization or arrangement or any other petition in bankruptcy or for
liquidation or to take advantage of any bankruptcy, insolvency or other debtors'
relief law of any jurisdiction, or (iii) ordering the dissolution, winding-up,
or liquidation of Tenant; or

     (f) This lease or any estate of Tenant hereunder is levied upon under any
attachment or execution and such attachment or execution is not vacated within
thirty (30) days

          16.2 If an Event of Default occurs, Landlord at any time thereafter
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. Upon such termination, Landlord shall have the right
to recover from Tenant;

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

     (b) The worth at the time of award of the amount by which all unpaid rent
which would have been earned after termination until the time of award exceeds
the amount of such rental loss that Tenant proves could have been reasonably
avoided;

     (c) The worth at the time of award of the amount by which all unpaid rent
for the balance of the term of this Lease after the time of award exceeds the
amount of such rental loss that Tenant proves could be reasonably avoided; and

     (d) All other amounts 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. The "worth at the time of award" of the amounts referred to in
clauses (a) and (b) above shall be computed by allowing interest at

19 - OFFICE LEASE

<PAGE>

the maximum annual interest rate allowed by law for business loans (not
primarily for personal, family or household purposes) not exempt from the usury
law at the time of termination or, if there is no such maximum annual interest
rate, at the rate of eighteen percent (18%) per annum. The "worth at the time of
award" of the amount referred to in clause (c) above shall be computed by
discounting such amount at the discount rate of the Federal Reserve Bank of San
Francisco at the time of award plus one percent (1%). For the purpose of
determining unpaid rent under clauses (a), (b), and (c) above, the rent reserved
in this Lease shall be deemed to be the total rent payable by Tenant under
Articles 3 and 5 hereof.

          16.3 Even though Tenant has breached this Lease, this Lease shall
continue in effect for so long as Landlord does not terminate Tenant's right to
possession, and Landlord shall have the right to enforce all its rights and
remedies under this Lease, including the right to recover all rent as it becomes
due under this Lease. Acts of maintenance or preservation or efforts to relet
the Premises or the appointment of a receiver upon initiative of Landlord to
protect Landlord's interest under this lease shall not constitute a termination
of Tenant's right to possession unless written notice of termination is given by
Landlord to Tenant.

          16.4 The remedies provided for in this Lease are in addition to all
other remedies available to Landlord at law or in equity by statue or otherwise.

          16.5 All agreements, covenants, and conditions to be performed or
observed by Tenant under this lease shall be at Tenant's sole cost and expense
and without any abatement of rent. If Tenant fails to pay any sum of money
required to be paid by Tenant hereunder or fails to perform any other act on
Tenant's part to be performed hereunder, Landlord shall have the right, but
shall not be obligated, and without waiving or releasing Tenant from any
obligations of Tenant, to make any such payment or to perform any such other act
on Tenant's part to be made or performed in accordance with this Lease. All sums
so paid by Landlord and all necessary incidental costs shall be deemed
additional rent hereunder and shall be payable by Tenant to Landlord on demand,
together with interest on all such sums from the date of expenditure by Landlord
to the date of repayment by Tenant at the maximum annual interest rate allowed
by law for business loans (not primarily for personal, family or household
purposes) not exempt from the usury law at the date of expenditure or, if there
is no such maximum annual interest rate, at the rate of eighteen percent (18%)
per annum. Landlord shall have, in addition to all other rights and remedies of
Landlord, the same rights and remedies in the event of the nonpayment of such
sums plus interest by Tenant as in the case of default by Tenant in the payment
of rent.

          16.6 If Tenant abandons or surrenders the Premises, or is dispossessed
by process of law or otherwise, any movable furniture, equipment, trade
fixtures, or personal property belonging to Tenant and left in the Premises
shall be deemed to be abandoned, at the option of Landlord, and Landlord shall
have the right to sell or otherwise dispose of such personal property in any
commercially reasonable manner.

                          ARTICLE 17 - Eminent Domain

          17.1 If thirty-three percent (33%) or less of the usable area of the
Premises is taken by exercise of the power of eminent domain before the
Commencement Date or during the term of this Lease, this Lease shall terminate
as to the portion of the Premises so taken as of the date of such taking and
shall remain in full force and effect as to the portion of the Premises not so
taken, and the Base Rent shall be reduced as of the date of such taking in the
proportion that the usable area of the Premises so taken bears to the total
usable area of the Premises. If more than thirty-three percent (33%), but less
than all, of the usable area of the Premises is taken by exercise of the power
of eminent domain before the Commencement Date or during the term of this Lease,
Landlord and Tenant each shall have the right, by giving written notice to the
other within thirty (30) days after the date of such taking, to terminate this
Lease. If either Landlord or Tenant exercises such right to terminate this Lease
in accordance with this Section 17.1, this Lease shall terminate as of the date
of such taking. If neither Landlord or Tenant exercises such right to terminate
this Lease in accordance with this Section 17.1, this Lease shall terminate as
to the portion of the Premises so taken as of the date of such taking and shall
remain in full force and effect as to the portion of the Premises not so taken,
and the Base Rent shall be reduced as of the date of such taking in the
proportion that the usable area of the Premises so taken bears to the total
usable area of the Premises. If all of the Premises is taken by exercise of the
power of eminent domain before the Commencement Date or during the term of this
Lease, this Lease shall terminate as of the date of such taking.

          17.2 If all or any part of the Premises is taken by exercise of the
power of eminent domain, all awards, compensation, damages, income, rent, and
interest payable in connection with such taking shall, except as expressly set
forth in this Section 17.2, be paid to and become the property of Landlord, and
Tenant hereby assigns to Landlord all of the foregoing. Without limiting the
generality of the foregoing, Tenant shall have no claim against Landlord or the
entity exercising the power of eminent domain for the value of the leasehold
estate created by this Lease or any unexpired term of this Lease. Tenant shall
have the right to claim and receive directly from the entity exercising the
power of eminent domain only the share of any award determined to be owing to
Tenant for the taking of improvements installed in the portion of the Premises
so taken by Tenant at Tenant's sole cost and expense based on the unamortized
cost actually paid by Tenant for such improvements, for the taking of Tenant's
movable furniture, equipment, trade fixtures, and personal property, for loss of
goodwill, for interference with or interruption of Tenant's business, or for
removal and relocation expenses.

          17.3 As used in this Article 17, a "taking" means the acquisition of
all or part of the Premises for a public use by exercise of the power of eminent
domain and the taking shall be considered to occur as of the earlier of the date
on which possession of the Premises (or part so taken) by the entity exercising
the power of eminent domain is authorized as stated in an order for possession
or the date on which title to the Premises (or part so taken) vests in the
entity exercising the power of eminent domain.

                  ARTICLE 18 - Subordination, Merger and Sale

          18.1 This Lease shall be subject and subordinate at all times to the
lien of all mortgages and deeds of trust securing any amount or amounts
whatsoever which may now exist or hereafter be placed on or against the Building
or on or against Landlord's interest or estate therein, all without the
necessity of having further instruments executed by Tenant to effect such
subordination. Notwithstanding the foregoing, in the event of a foreclosure of
any such mortgage or deed of trust or of any other action or proceeding for the
enforcement thereof, or of any sale thereunder, this Lease shall not be
terminated or extinguished, nor shall the rights and possession of Tenant
hereunder be disturbed, if no event of Default then exists under this Lease, and
Tenant shall attorn to the person who acquires Landlord's interest hereunder
through any such mortgage or deed of trust. Tenant agrees to execute,
acknowledge, and deliver upon demand such further instruments evidencing such
subordination of this Lease to the lien of all such mortgages and deeds of trust
as may reasonably be required by Landlord, but Tenant's covenant to subordinate
this Lease to mortgages or deeds of trust hereafter executed is conditioned upon
each such senior mortgage or deed of trust, or a separate subordination
agreement, containing the commitments specified in the preceding sentence.

          18.2 The voluntary or other surrender of this Lease by Tenant, or a
mutual cancellation thereof, shall not work a merger and shall, at the option of
Landlord, terminate all or any existing subleases or subtenancies or operate as
an assignment to Landlord of any or all such subleases or subtenancies.

          18.3 If the original Landlord hereunder, or any successor owner of the
Building, sells or conveys the Building, all liabilities and obligations on the
part of the original Landlord, or such successor owner, under this Lease
accruing after such sale or conveyance shall terminate and the original
Landlord, or such successor owner, shall automatically be released therefrom,
and thereupon all such liabilities and obligations shall be binding upon the new
owner. Tenant agrees to attorn to such new owner.

                       ARTICLE 19 - Estoppel Certificate

          19.1 At any time and from time to time but in any event within ten
(10) days after written request by Landlord, Tenant shall execute, acknowledge
and deliver to Landlord, promptly upon request, a certificate certifying: (a)
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
stating the date and nature of each modification); (b) the Commencement Date and
the Expiration Date determined in accordance with Article 2 hereof and the date,
if any, to which all rent and other sums payable hereunder have been paid; (c)
that no notice has been received by Tenant of any default by Tenant hereunder
which has not been cured, except as to defaults specified in such certificate;
(d) that Landlord is not in default hereunder, except as to defaults specified
in such certificate; and (e) such other matters as may be reasonably requested
by Landlord or any actual or prospective purchaser or mortgage lender. Any such
certificate may be

<PAGE>

relied upon by Landlord and any actual or prospective purchaser, mortgagee or
beneficiary under any deed of trust of the Building or any part thereof.

                           ARTICLE 20 - Holding Over

          20.1 If, without objection by Landlord, Tenant holds possession of the
Premises after expiration of the term of this Lease, Tenant shall become a
tenant from month to month upon the terms herein specified but at a Base Rent
equal to one hundred fifty percent (150%) of the Base Rent payable by Tenant at
the expiration of the term of this Lease pursuant to Article 3 hereof, payable
in advance on or before the first day of each month. Such month to month tenancy
may be terminated by either Landlord or Tenant by giving thirty (30) days'
written notice of termination to the other at any time

                               ARTICLE 21- Waiver

          21.1 The waiver by Landlord or Tenant of any breach of any covenant in
this Lease shall not be deemed to be a waiver of any subsequent breach of the
same or any other covenant in this Lease, nor shall any custom or practice which
may grow up between Landlord and Tenant in the administration of this Lease be
construed to waive or to lessen the right of Landlord or Tenant to insist upon
the performance by Landlord or Tenant in strict accordance with this Lease. The
subsequent acceptance of rent hereunder by Landlord or the payment of rent by
Tenant shall not waive any preceding breach by Tenant of any covenant in this
Lease, nor cure any Event of Default, nor waive any forfeiture of this Lease or
unlawful detainer action, other than the failure of Tenant to pay the particular
rent so accepted, regardless of Landlord's or Tenant's knowledge of such
preceding breach at the time of acceptance or payment of such rent.

                           ARTICLE 22 - Force Majeure

          22.1 Whenever a day is appointed herein on which, or a period of time
is appointed within which, either party hereto is required to do or complete any
act, matter or thing, the time for the doing or completion thereof shall be
extended by a period of time equal to the number of days on or during which such
party is prevented from, or is unreasonable interfered with, the doing or
completion of such act, matter or thing because of strikes, lock-outs,
embargoes, unavailability of labor or materials, wars, insurrections,
rebellions, civil disorder, declaration of national emergencies, acts of God, or
other causes beyond such party's reasonable control (financial inability
excepted); provided, however, nothing contained in this Section 22.1 shall
excuse Tenant from the prompt payment of any rental or other charge required of
Tenant hereunder except as may be expressly provided elsewhere in this Lease.

                              ARTICLE 23 - Notices

          23.1 All notices and other communications which may or are required to
be given by either Landlord or Tenant to the other under this Lease shall be
deemed to have been

23 - OFFICE LEASE

<PAGE>

fully given when made in writing and hand delivered or deposited in the United
States Mail, postage prepaid, certified with return receipt requested, and
addressed as follows: to Tenant at the address of Tenant specified in the Basic
Lease Information, or at such other place as Tenant may from time to time
designate in a notice to Landlord, or, after the Commencement Date at the
Premises; to Landlord at the address of Landlord specified in the Basic Lease
Information, or at such other place as Landlord may from time to time designate
in a notice to Tenant.

                           ARTICLE 24 - Miscellaneous

          24.1 The words "Landlord" and "Tenant" as used herein shall include
the plural as well as the singular. Tenant shall indemnify and defend Landlord
against and hold Landlord harmless from all claims, demands, liabilities,
damages, losses, costs and expenses, including, without limitation, reasonable
attorneys' fees, arising out of or resulting from any failure by Tenant to
perform any of its obligations or any breach by Tenant of any of its
representations or warranties in accordance with this Lease. If there is more
than one Tenant, the obligations hereunder imposed upon Tenant shall be joint
and several. Time is of the essence of this Lease and each and all of its
provisions. Submission of this instrument for examination or signature by Tenant
does not constitute a reservation of or option for lease, and it is not
effective as a lease or otherwise until execution and delivery by both Landlord
and Tenant. Subject to Article 13 hereof, this Lease shall benefit and bind
Landlord and Tenant and the personal representatives, heirs, successors, and
assigns or Landlord and Tenant. Tenant shall not, without the prior written
consent of Landlord, use the name of the Building for any purposes other than as
the address of the business to be conducted by Tenant in the Premises. If any
provision of this Lease is determined to be illegal or unenforceable, such
determination shall not affect any other provision of this Lease and all such
other provisions shall remain in full force and effect. If Tenant requests the
consent or approval of Landlord to any assignment, sublease or other action by
Tenant, Tenant shall pay on demand to Landlord all costs and expenses,
including, without limitation, reasonable attorneys' fees, incurred by Landlord
in connection therewith. This Lease shall be governed by and construed in
accordance with the laws of the State of California.

          24.2 Tenant acknowledges that the late payment by Tenant of any
monthly installment of Base Rent or additional monthly rent will cause Landlord
to incur costs and expenses, the exact amount of which is extremely difficult
and impractical to fix. Such costs and expenses will include, without
limitation, administration and collection costs and processing, and accounting
expenses. Therefore, if any monthly installment of Base Rent or additional
monthly rent is not received by Landlord from Tenant within ten (10) days after
such installment is due, Tenant shall immediately pay to Landlord a late charge
equal to four percent (4%) of such delinquent installment. Landlord and Tenant
agree that such late charge represents a reasonable estimate of such costs and
expenses and is fair compensation to Landlord for its loss suffered by Tenant's
failure to make timely payment. In no event shall such late charge be deemed to
grant to Tenant a grace period or extension of time within which to pay any
monthly rent or prevent Landlord from exercising any right or remedy available
to Landlord upon Tenant's failure to pay each installment of monthly rent due
under this Lease in a timely fashion, including the right to

24 - OFFICE LEASE

<PAGE>

terminate this Lease. All amounts of money payable by Tenant to Landlord
hereunder, if not paid when due, shall bear interest from the due date until
paid at the maximum annual interest rate allowed by law for business loans (not
primarily for person, family or household purposes) not exempt from the usury
law at such due date or, if there is no such maximum annual interest rate, at
the rate of eighteen percent (18%) per annum.

          24.3 If there is any legal action or proceeding between Landlord and
Tenant to enforce any provision of this Lease or to protect or establish any
right or remedy of either Landlord or Tenant hereunder, the unsuccessful party
to such action or proceeding shall pay to the prevailing party all costs and
expenses, including reasonable attorneys' fees, incurred by such prevailing
party in such action or proceeding and in any appeal in connection therewith. If
such prevailing party recovers a judgment in any such action, proceeding or
appeal, such costs, expenses and attorneys' fees shall be included in and as a
part of such judgment.

          24.4 Exhibit "A" (Plan(s) Outlining the Premises), and Exhibit "B"
(Rules and Regulations) are attached to and made a part of this Lease.

          24.5 Tenant warrants and represents to Landlord that Tenant has
negotiated this Lease directly with Landlord and that no real estate broker are
agent has been engaged by Tenant in connection with this Lease. Tenant shall
indemnify and hold harmless Landlord from any breach by Tenant of the foregoing
representation and warranty.

          24.6 If Tenant is a corporation, Tenant and each person executing this
Lease on behalf of Tenant represents and warrants that (a) Tenant is duly
incorporated and validly existing under the laws of its state of incorporation,
(b) Tenant is qualified to do business in California, (c) Tenant has full
corporate right, power and authority to enter into this Lease and to perform all
of Tenant's obligations hereunder, and (d) each person signing this Lease on
behalf of the corporation is duly and validly authorized to do so.

          23.7 There are no oral agreements between Landlord and Tenant
affecting this Lease, and this Lease supersedes and cancels any and all previous
negotiations, arrangements, brochures, offers, agreements and understandings,
oral or written, if any, between Landlord and Tenant or displayed by Landlord to
Tenant with respect to the subject matter of this Lease, the Premises or the
Building. There are no representations between Landlord and Tenant or between
any real estate broker and Tenant other than those expressly set forth in this
Lease and all reliance with respect to any representations is solely upon
representations expressly set forth in this Lease. This Lease may not be amended
or modified in any respect whatsoever except by an instrument in writing signed
by Landlord and Tenant.

          24.8 Clauses, plats, and riders, if any, signed or initialed by
Landlord and Tenant and affixed to this lease are a part hereof.

25 - OFFICE LEASE

<PAGE>

          24.9 Tenant shall be entitled to the non-exclusive use of sixty-eight
(68) unreserved parking spaces in the parking area serving the Building during
Tenant's occupancy of the Premises pursuant to any rules and regulations
Landlord may establish with respect to the use of such parking spaces. Such
parking spaces shall be provided to Tenant at no charge through the term of this
Lease.

          24.10 No determination by any court, governmental body, or otherwise
that any provision of this lease or any amendment hereof is invalid or
unenforceable in any instance shall affect the validity or enforceability of any
other such provision or such provision in any circumstance not controlled by
such determination. Each such provision shall be valid and enforceable to the
fullest extent allowed by, and shall be construed wherever possible as being
consistent with, applicable law.

                          ARTICLE 25 - Quiet Enjoyment

          25.1 Landlord hereby covenants that Tenant, on paying rent and all
other sums owing hereunder and performing the covenants set forth herein, shall
peaceably and quietly hold and enjoy the Premises throughout the Term and such
rights as the Tenant may hold hereunder with respect to the remainder of the
Building.

                      ARTICLE 26 - Right of First Refusal

          26.1 Subject to the terms and conditions contained herein, Tenant
shall, during the Term of this Lease, have a Right of First Refusal in regard to
all space located on the second floor of the Building (the "Adjacent Space").

          26.2 If during the Term of this Lease Landlord has reached a
preliminary agreement with a bona fide prospective tenant ("Prospective
Tenant'") as to the essential terms of a proposal for leasing all or any portion
of the Adjacent Space, which Landlord intends shall serve as the basis for
negotiating a lease with the Prospective Tenant (such preliminary agreement to
be referred to herein as a "Proposal"), Landlord shall first provide Tenant with
a notice ("Landlord's Notice") which informs Tenant of the Proposal and sets
forth the basic elements of such Proposal, including without limitation, an
approximate description of the space subject to the Proposal (the "Prospective
Tenant Premises"), the total proposed rentable square feet, the term, base rent,
options to extend, expand, or terminate, the amount of any allowances, and any
other material concessions or elements. Within ten (10) business days following
Landlord's Notice, Tenant shall have the right to lease the Prospective Tenant
Premises upon the terms set forth in Landlord's Notice, and subject to the
provisions set forth below in this Article 26, by providing Landlord with
written notice of its intent to exercise such right. Should Tenant indicate that
it is not prepared to lease the Prospective Tenant Premises, whether by written
notice to Landlord or by failing to respond to Landlord's Notice within the said
ten (10)-business day period, then Tenant shall be deemed to have waived its
Right of First Refusal, with respect to the Prospective Tenant Premises.

26 - OFFICE LEASE

<PAGE>

          26.3 In each event that Tenant exercises its Right of First Refusal,
Landlord and Tenant shall enter into an amendment to this Lease adding the
Prospective Tenant Premises to the Premises, subject to all of the terms and
conditions, including Lease Term, which were set forth in the applicable
Landlord's Notice. The effective date of Tenant's leasing of the Prospective
Tenant Premises (the "Refusal Space Effective Date") shall be the earlier of:(i)
the date Tenant begins to operate its business from the Prospective Tenant
Premises; or (ii) the date Landlord delivers possession of the Prospective
Tenant Premises to Tenant with any and all agreed upon improvements
substantially complete.

          26.4 Except as specifically provided otherwise in the applicable
Landlord's Notice, any Prospective Tenant Premises leased by Tenant pursuant to
this Article 26 shall be leased in"as-is" condition, and all other improvements
in the applicable portion of the Prospective Tenant Premises shall be Tenant's
responsibility at Tenant's cost, and shall be made in accordance with the terms
of this Lease. The rights of Tenant under this Article 26 are personal to Tenant
and shall not be severed from this Lease or separately sold, assigned, or
otherwise transferred.

          26.5 The rights of Tenant hereunder are subject to the rights of other
tenants with respect to the Adjacent Space pursuant to leases in existence as
of the date of this Lease.

     IN WITNESS WHEREOF, Landlord and Tenant have executed this Office Lease as
of the date first hereinabove written.

                            First Amendment to Lease

     THIS FIRST AMENDMENT TO LEASE, dated as of the 15rh day of January, 1999,
is between PROPERTY CALIFORNIA OB ONE CORPORATION, an Oregon corporation
("Landlord") and INDYMAC, INC., a Delaware corporation ("Tenant").

                                 R E C I T A L S

     A. Landlord and Tenant entered into that certain written lease agreement
dated July 8, 1998 (the "Lease"), pursuant to which Landlord leased unto Tenant
and Tenant leased from Landlord approximately 19,361 rentable square feet of
space commonly known as Suite 101 (the "Premises") located in that certain
office building known as 15050 Avenue of Science located in San Diego,
California (the "Building"), as more particularly described in the Lease.

     B. Pursuant to the Work Letter attached to the Lease as Exhibit "C",
Landlord was to complete certain Initial Improvements (as defined in paragraph
1.1 of the Work Letter) within the Premises before the Commencement Date of the
Lease. At the time the Lease was executed, the parties anticipated that Landlord
would complete all of the Initial Improvements at one time. Due to unforseen
circumstances, the parties agreed that the Initial Improvements would be
completed in phases. Prior to the date of this Amendment, the parties agreed to
a phase build out of the Premises. However, due to further unforeseen
circumstances affecting Tenant, the parties did not reach agreement on the final
price or construction schedule for the phased build out of the Premises.
Notwithstanding such unforeseen circumstances, Landlord has been and is ready,
willing, and able to construct the Initial Improvements pursuant to a phased
build out of the Premises.

     C. Tenant has recently disclosed to Landlord that due to unforeseen
circumstances affecting Tenant, Tenant is re-evaluating Tenant's overall space
needs in the Building. Tenant has requested that Landlord delay the construction
of the Initial Improvements and grant Tenant additional time to re-evaluate its
space needs. Landlord is willing to delay such construction if Tenant commences
the payment of Base Rent for the Premises as set forth in this Amendment and
advises Landlord by March l, 1999, regarding its space needs and the
Construction Schedule.

                                A G R E E M E N T

     NOW, THEREFORE, for and in consideration of the facts mentioned above, the
mutual promises set forth below and other good and valuable consideration, the
sufficiency and receipt of which is hereby acknowledged, the parties hereto do
agree as follows:

1 -  FIRST AMENDMENT TO LEASE

<PAGE>

     1. Effective Dates. Except as otherwise set forth herein, the amendments to
the Lease outlined below shall be effective as of the date this Amendment is
fully executed by the parties hereto.

     2. Capitalized Terms. All capitalized terms used herein shall have the
meanings ascribed to them in the Lease, unless otherwise defined herein.

     3. Deadline for Tenant's Decision to Proceed.

          (a) On or before March 1, 1999, Tenant shall notify Landlord in
writing of its decisions regarding its space needs and the build out schedule,
provided that Tenant will provide Landlord with any meaningful information
regarding its space requirements as soon as such information is available, and
Tenant shall provide Landlord with written status reports of its space
requirements on February l.

          (b) The parties agree to discuss and revise the build out provisions
in the Lease, as amended, to document the mutual decisions of the parties
related to Tenant's space needs and build out schedule.

     4. Composition of Premises. The Premises, measuring a total of 19,361
rentable square feet, consist of the following individual spaces: 11,184
rentable square feet (the "Original Space"); 4,308 square feet (the "Phase I
Space"), and 3,869 square feet (the "Phase H Space"). The Original Space
consists of two parts. A portion of the Original Space (627 square feet) is
currently on a month-to-month rental agreement. The balance, 10,557 is covered
by a lease agreement reflecting a base rent of $1.30/square foot per month.

     5. Original Space. Tenant shall continue to pay Landlord the rent required
under the prior lease and rental agreement for the Original Space, which amount
is Fourteen Thousand Seven Hundred Fifty-eight and 65/100 Dollars ($14,758.65)
per month. Beginning April 1, 1999 and continuing for the term of the Lease,
Tenant shall pay Landlord monthly Base Rent for the Original Space, equal to the
sum of 11,184 square feet multiplied by $1.60 per month, which amount is part of
the monthly base rent set forth in paragraph 7 below.

     6. Phase I Space. Notwithstanding anything to the contrary in the Lease,
beginning on January 15, 1999 (the "Phase I Rent Commencement Date"), Tenant
shall pay Landlord monthly Base Rent in the amount of Six Thousand Eight Hundred
Ninety-two and 80/100 Dollars ($6,892.80) for the Phase I Space. The Januarv.
1999 rent payment for the Phase I Space will be prorated. The monthly rental for
the Phase I Space will be in addition to the rental for the Original Space.

     7. Phase II Space Build-Out. Notwithstanding anything to the contrary in
the Lease, beginning on the April l, 1999 Phase 11 Rent Commencement Date,
Tenant shall pay Landlord monthly Base Rent in the aggregate amount of Thirty
Thousand Nine Hundred

                         CONSENT TO ASSIGNMENT OF LEASE

     THIS ASSIGNMENT, ASSUMPTION AND CONSENT TO ASSIGNMENT OF LEASE (the
"Agreement") is made as of 11/11, 1999 by and among PROPERTY CALIFORNIA OB ONE
CORPORATION, an Oregon corporation ("Landlord"), INDYMAC, INC., a Delaware
corporation ("Assignor"), and OLD KENT MORTGAGE COMPANY, a Michigan corporation
("Assignee").

                                 R E C I T A L S

     1. Landlord and Assignor, as Tenant, entered into that certain Office
Lease, dated July 8, 1998, as amended by that certain First Amendment to Lease
dated January 15, 1999 (collectively, the "Lease") for approximately 19,361
rentable square feet of space ("Premises") known as Suite 101 at the office
building having an address of 15050 Avenue of Science ("Building"), which is
located in San Diego, California, as more fully described in the Lease.

     2. Assignor desires to assign its interest in and to the Lease to Assignee
and Assignee desires to accept such assignment, on the terms and conditions set
forth herein.

     3. Section 13.1 of the Lease requires Landlord's written approval of any
proposed assignment of the Lease and Landlord has agreed to grant such approval
subject to the terms of this Agreement.

                                A G R E E M E N T

     NOW, THEREFORE, for and in consideration of the facts mentioned above, the
mutual promises set forth below and other good and valuable consideration, the
sufficiency and receipt of which is hereby acknowledged, the parties hereto do
agree as follows:

     1. Assignor represents and warrants to Landlord and Assignee:

          (a) that it is the holder of the Tenant's interests in the Lease and
has good right to assign such interests in the same, and that no other person,
firm or corporation has any right, title or interest therein;

          (b) that Assignor has duly and punctually performed all the terms,
covenants, conditions, and warranties of the Lease on Assignor's part to be
kept, observed and performed;

          (c) that the Lease is valid and unmodified, except as indicated
herein, and is in full force and effect; and

1 -    ASSIGNMENT, ASSUMPTION AND CONSENT TO ASSIGNMENT OF LEASE

<PAGE>

          (d) that Assignor has not previously assigned the Lease.

     2. Assignor does hereby assign to Assignee all of its right, title and
interest in the Lease as of November 1, 1999.

     3. As of November 1, 1999, Assignee accepts, assumes and agrees to make all
payments due and owing under the Lease directly to Landlord and to be bound by
and perform all covenants, conditions, obligations, and duties of Assignor under
the Lease, and will indemnify and hold harmless Assignor from all damages of any
nature arising out of its failure to do so. If Assignee defaults under the
Lease, Assignor may proceed directly against Assignee without pursuing remedies
against Landlord.

     4. Provided that this Agreement is fully executed, Landlord consents to the
assignment of Assignors interests in and to the Lease to Assignee, but does not
waive any rights. Landlord has against Assignor, nor does Landlord release
Assignor from its liabilities and obligations under the Lease. Assignor shall
remain responsible to Landlord for any and all payment obligations under the
Lease, as well as for the faithful performance of all of the terms and
conditions in the Lease. If Assignee defaults under the Lease, Landlord may
proceed directly against Assignor without pursuing remedies against Assignee;
provided, however, Landlord shall give Assignor written notice of Assignee's
default and, upon such notice, Assignor shall be entitled to the amount of time
set forth in any applicable cure periods contained in the Lease to cure said
default.

     5. Landlord warrants, to the best of its actual knowledge, that as of the
date of this Agreement, the Lease is in full force and effect and that Assignor
is not in default in the performance or observance of any of the terms,
provisions or obligations imposed on Assignor under the Lease.

     6. Landlord covenants and represents that it is the holder of the interests
of Landlord under the Lease, and has full right and authority to enter into this
Agreement.

     7. All monies previously paid by Assignor to Landlord as a security deposit
in connection with the Lease, if any, shall be retained by Landlord as the
security deposit for the Premises, regardless of this Agreement. Any portion of
the security deposit required to be returned by Landlord to the Lease's "Tenant"
at the termination of the Lease, if any, shall be disbursed to Assignee.
Assignor releases Landlord from any and all claims, liabilities, or obligations
associated with the retention and/or disbursement of any security deposit
related to the Premises.

     8. In connection with the Initial Improvements (as defined in paragraph 1.1
of the Work Letter attached to the Lease), Assignee acknowledges and agrees to
the following:

2 -    ASSIGNMENT, ASSUMPTION AND CONSENT TO ASSIGNMENT OF LEASE

<PAGE>

(i) Assignee has been made fully aware of the status of and the circumstances
surrounding the construction of the Initial Improvements (as defined in the
Lease); (ii) Landlord has been ready, willing and able to perform the Initial
Improvements, but has been delayed in completing such improvements by Assignor's
requests to postpone the construction; (iii) Landlord is not in default in any
respect in connection with the Initial Improvements; (iv) as of the date of this
Agreement, the sum of Thirty-One Thousand Seven Hundred Eleven and 10/100
Dollars ($31,711.10) has been incurred by Landlord in connection with (a)
initial and revised construction drawings of the Initial Improvements, and (b)
the build-out of a conference room within the Premises, and that such sum shall
offset the Allowance (as defined in Section 2.1 of the Work Letter attached to
the Lease) such that the remaining Allowance as of the date of this Agreement is
One Hundred Seventeen Thousand Nine Hundred Fifty-Six and 90/100 Dollars
($117,956.90); and (v) if Assignee desires to make any changes to the current
construction drawings of the Initial Improvements, Assignee shall inform
Landlord in writing of any such changes within ninety (90) days after this
Agreement is executed and the costs to make any such changes shall further
reduce the amount of the remaining Allowance.

     9. Assignee acknowledges and agrees that Article 26 of the Lease extended a
personal right of first refusal to Assignor and, pursuant to the terms of said
article, such right is not transferable to Assignee. Therefore, Assignee shall
not be entitled to exercise the right of first refusal set forth in Article 26
of the Lease.

     10. As of the date of this Agreement, all notices required to be given by
Landlord to the tenant under the Lease shall be sent to Assignee at the
Premises.

     11. Except as expressly provided herein, no provision of this Agreement
alters or modifies any of the terms and conditions of the Lease.

     12. If any provision of this Agreement or its application to any entity,
person or circumstance shall be invalid or unenforceable to any extent, the
remainder of this Agreement and the application of such provisions to other
entities, persons or circumstances shall not be affected and shall be enforced
to the greatest extent permitted by law.

     13. This document contains the entire agreement between the parties
regarding the matter addressed by this Agreement. No variations, modifications
or changes relating to this Agreement shall be binding upon any party unless set
forth in a document duly executed by or on behalf of such party.

     14. Each party represents that the person executing this Agreement for such
party is acting on behalf of such party and is duly authorized to execute this
Amendment for such parry.

     15. The parties hereby warrant and represent that they have not retained
the services of any real estate broker in connection with this Agreement.

     from any and all claims, liabilities, or obligations associated with the
     retention and/or disbursement of any security deposit related to the
     Premises.

     2. ASSIGNMENT, ASSUMPTION AND CONSENT TO ASSIGNMENT OF LEASE

     affected and shall be enforced to the greatest extent permitted by law.
