excess ("Operating cost Payments"). "Tenant's Share" means 16.33%, which is
calculated by dividing the rentable square footage of the Premises by the
rentable square footage of the Building as such rentable square footages are set
forth in Paragraph 1, and multiplying such number by 100.

                  5.3 OPERATING COSTS LIMITATION. Landlord agrees that for the
purposes of calculating Tenant's share of any increases in Building Operating
costs, the "Controllable Operating Cost" portion of Building Operating Costs
(i.e. expenses other than expenses for water, gas, electricity, telephone,
scavenger, real and personal property taxes and assessments, license and permit
fees, and or expenses to comply with governmental regulations after the
commencement date) for any year after the Base Year shall be limited to the
Controllable Operating Costs used in determining the Expense Stop plus a
cumulative six percent (6%) annually compounded increase. Except as otherwise
provided for in this Lease, there shall be no limit on the increases in
Non-Controllable Operating Costs. In the event of a sale, transfer of ownership,
or refinancing of the Building during the term of this Lease, Landlord
guarantees that no resultant tax increase will be passed through to Tenant.

                  5.4 NOTICE AND PAYMENT. As soon as reasonably practical after
the end of each calendar year following the Base Year, Landlord shall furnish
Tenant a written statement showing in reasonable detail the operating Costs for
the preceding calendar year, and the amount of any payment due from Tenant to
Landlord or from Landlord to Tenant, taking into account prior operating Cost
Payments made by Tenant for such preceding calendar year. Tenant shall have one
hundred eighty (180) days after receipt of Landlord's statement to notify
Landlord of any objections they have to such statement, or of their intention to
review supporting documentation for such statement. If Tenant does not so notify
Landlord, such statement shall conclusively be deemed correct and Tenant shall
have no right thereafter to dispute or review support for such statement any
item therein, or the computation of Operating costs. If Tenant does so notify
the Landlord within the one hundred eighty (180) day period, Tenant shall have


                                       6
<PAGE>

one (1) year from the date of receipt of Landlord's statement to complete their
review of the supporting documentation and notify landlord of all objections, if
any, to such statement. After this one (1) year period, it will be assumed that
Landlord has been notified of all objections by Tenant to Landlord's statement
and that no further review of supporting documentation is necessary. If there
are no objections, Tenant shall have no further rights thereafter to dispute
such statement any item therein, or the computation of Operating Costs. Any
notifications to Landlord will be done in accordance with Paragraph 25.14.

                  Coincidentally with the monthly Base Rent next due following
Tenant's receipt of such statement, Tenant shall pay to Landlord (in the case of
an underpayment) or Landlord shall credit against the next Base Rent due from
Tenant (in the case of an overpayment) the difference between (i) Tenant's Share
of any excess of operating Costs for the preceding calendar year over the
Expense Stop (the "Prior Year's Increase") and (ii) the Operating cost Payments
made by Tenant for such preceding calendar year. In addition, Tenant shall pay
to Landlord coincidentally with such next due Bass Rent an amount equal to (A)
one-twelfth (1/12) of the prior Year's Increase, it any, multiplied by (B) the
number of months or partial months (including the then current month) then
elapsed in the current calendar year, less (C) the aggregate of any operating
Cost Payments made by Tenant for such current calendar year. Monthly thereafter
until adjustment is made the following year pursuant to this paragraph, Tenant
shall pay together with the monthly Base Rent one-twelfth (1/12) of any such
Prior Year's Increase. In no event will Tenant be entitled to receive the
benefit of a reduction in operating Costs below the Expense Stop.

                  For any partial calendar year at the termination of this
Lease, Tenant's Share of any increases in Operating Costs for such year over the
Expense Stop shall be prorated on the basis of a 365-day year by computing
Tenant's Share of the increases in Operating Costs for the entire year and then
prorating such amount for the number of days this Lease was in effect during
such year. Notwithstanding the termination of this Lease, and within ten (10)
days after Tenant's receipt of Landlord's statement regarding the determination
of increases in Operating Costs for the calendar year in which this Lease
terminates, Tenant shall pay to Landlord or Landlord shall pay to Tenant, as the
case may be,, an amount equal to the difference between Tenant's Share of the
increases in Operating Costs for such year (as prorated) and the amount
previously paid by Tenant toward such increases.

                  5.5 ADDITIONAL TAXES. Tenant shall reimburse to Landlord,
within thirty (30) days after receipt: of a demand therefor, Tenant's Share of
any and all taxes payable by Landlord (other than net income taxes or any taxes
included within Operating Costs), whether or not now customary or within the
contemplation or the parties hereto (i) upon, allocable to or measured by the
area of the Building, (ii) upon all or any portion of the Rent payable hereunder
and under other leases of space in the Building, including any gross receipts
tax or excise tax levied with respect to the receipt of such Rent, or (iii) upon
or with respect to the possession leasing, operation, management, maintenance,
alteration, repair, use or occupancy of the Building or any portion thereof.
Tenant shall not be required to reimburse Landlord for taxes under this
Paragraph 5.5 to the extent Tenant has paid Tenant's Share of such taxes through
operating cost Payments under Paragraph 5.2. In the event of a sale, transfer of
ownership, or refinancing of the building during the term of this lease,
Landlord guarantees that no resultant tax increase will be passed through to
Tenant.

                  5.6 TENANT'S RIGHT TO, AUDIT. In the event of any dispute or
uncertainty as to the amount of Operating Costs and Tenant's Share thereof
(including calculation of the Expense Stop under Subsection 5.2), Tenant may
require clarification as to any disputed amount, including without limitation,
receiving and reviewing legible copies of all of Landlord's invoices and paid
receipts, with respect to the disputed items, and pursuing an audit as
hereinafter specified, provided Tenant notifies Landlord in writing within one
hundred eighty (180) days of its receipt of Landlord's statement that Tenant
elects to inspect and/or audit such records pursuant to this Section. Should
Tenant elect to inspect and/or audit such records, Tenant's inspection and/or
audit shall be completed and the results thereof submitted to Landlord no later
than one year after Tenant's receipt of Landlord's statement. If Landlord and
Tenant are unable to agree as to any disputed item, Tenant may, at its sole cost
and expense, audit on its own (or engage an independent certified public
accounting firm to audit) Landlord's accounting records related to the disputed
items, which audit shall be scheduled promptly at the reasonable convenience of
both Landlord and Tenant, such audit to take place in Landlord's offices. If the
results of such audit by an independent CPA approved by Landlord, whose approval
shall not be unreasonably withheld, and Tenant indicate that the aggregate cost
of the disputed item is incorrect, then the Landlord shall refund the
discrepancy, and if the amount of the discrepancy is more than five percent
(5%), then Landlord shall pay for the reasonable cost of the audit, (not to
exceed $5,000.00), as well as refund the discrepancy amount.

                  5.7 TENANT'S TAXES. Tenant shall pay before delinquency
(whether levied on Landlord or Tenant), any and all taxes assessed upon or
measured by (i) Tenant's equipment, furniture, fixtures and other personal
property located in the Premises, (ii) any improvements or alterations made to
the Premises prior to or during the term of this Lease paid for by Tenant after
initial build out of Tenant's improvements, or (iii) this transaction or any
document to which Tenant is a party creating or transferring an interest or an
estate in the Premises. For the purpose of determining said amounts, figures
supplied by the County Assessor as to the amount so assessed shall be
conclusive. Tenant shall comply with the provisions of any law, ordinance or
rule of the taxing authorities which require Tenant to file a report of Tenant's
property located in the Promises.

         6.       USE

                  6.1 USE. The Premises shall be used and occupied y Tenant for

the Premises or the Building or with respect to the suitability of either for
the conduct of Tenant's business, nor has Landlord agreed to undertake any
modification, alteration or improvement to the Premises except as provided in
the Work Letter. The taking of possession of the Premises by Tenant shall
conclusively establish that the Premises and the Building were at such time in
satisfactory condition, except for hidden or latent defects, unless within
thirty (30) days after such date Tenant shall give Landlord written notice
specifying in reasonable detail the respects in which the Premises or the
Building were not in satisfactory condition.

done in or about the Premises nor bring or keep anything therein which will in
any way increase the existing rate or affect any fire or other insurance upon
the Building or any of its contents, or cause a cancellation of any insurance

shall Tenant sell or permit to be kept, used or sold in or about said Premises
any articles which may be prohibited by a standard form policy of fire
insurance.

or occupancy of the Premises, excluding structural changes not relating to or
affecting the condition, use or occupancy of the Premises or Tenant's
improvements or acts. The judgment of any court of competent jurisdiction or the
admission of Tenant in. any action against Tenant, whether Landlord be a party
thereto or not, that Tenant has violated any law, statute, ordinance or
governmental rule, regulation or requirement, shall be conclusive of the fact as
between Landlord and Tenant. Tenant's obligation under this Paragraph shall be
limited to those situation in which a violation of law or non-compliance with a
rule or regulation results from the particular use made of the Premises or any
portion thereof by Tenant, it being understood that Tenant shall not be
responsible for complying with any violations, orders, codes or duties which are

exist, Tenant shall not be entitled to terminate this Lease on account of such
failure. Landlord shall not be liable under any circumstances for loss of or
injury to property or business or consequential damages, however occurring,

policies shall in no event limit the liability of Tenant hereunder. The
aforesaid insurance shall name Landlord and its partners property manager, and
mortgagees as an additional insured. said insurance shall be with companies

shall furnish from the insurance companies or cause the insurance companies to
furnish


                                       14

certificates of coverage. No such policy shall be cancelable or subject to
reduction of coverage or other modification or cancellation except after thirty
(30) days prior written notice to Landlord by the insurer. All such policies
shall be written as primary policies, not contributing with and not in excess of
the coverage which Landlord may carry. Tenant shall,, at least twenty (20) days
prior to the expiration of such policies, furnish Landlord with evidence of
renewals or binders. Tenant agrees that it Tenant does not take out and maintain
such insurance, Landlord nay (but shall not be required to) procure said
insurance on Tenant's behalf and charge Tenant the premiums together with a
reasonable handling charge and Default Interest from the date paid by Landlord,
payable upon demand. Tenant shall have the right a provide such insurance
coverage pursuant to blanket policies obtained by Tenant, provided such blanket
policies expressly afford coverage to the Premises and to Tenant as required by
this Lease.

                  12.3 WAIVER OF SUBROGATION. To the extent permitted by their
respective policies of insurance, Landlord and Tenant each hereby waive any
right of recovery against the other and the authorized representatives of the
other for any loss or damage that is covered by any policy of insurance
maintained by either party with respect to the Premises or the Project or any
operation therein. If any policy of insurance relating to this Lease, the
Premises or the Project does not permit the foregoing waiver or if the coverage
under any such policy would be invalidated as a result of such waiver, the party
maintaining such policy shall, if possible, obtain from the insurer under such
policy a waiver of all right of recovery by way of subrogation against either
party in connection with any claim, loss or damage covered by such policy.

                  12.4 SELF-INSURANCE OPTION. Tenant may elect at any time
during the term of this Lease not to carry liability and property damage
insurance required above and to "self insure" against such risks provided that
(i) Tenant has in effect a program of "self insurance" against such risks, (ii)
Tenant has and maintains a not worth of at lease ONE HUNDRED MILLION DOLLARS
($100,000,000.00) as evidenced by documentation reasonably satisfactory to
Landlord, and (iii) the failure to carry such Insurance does not violate any
law, statute, code, act, ordinance, order, judgment, decree, injunction, rule,
regulation, permit, license, authorization or other requirement which is issued
by the government or governmental agency with jurisdiction over the Leased
Premises which is applicable to Tenant in the conduct of its business. In the
event Tenant elects to self insure, Tenant agrees to provide Landlord with
written notice and evidence of such self insurance with coverage not less than
that called out for in this Lease.

                  12.5 LANDLORD'S INSURANCE. During the term hereof, Landlord
shall keep the Building and all Tenant Improvements to the Premises insured
through reputable insurance underwriters against perils covered by a standard
"all risk" insurance policy or policies as such policies are in use as of the
dare of this Lease (excluding perils such as flood and other standard "all risk"
policy form exclusions) in an amount or amounts equal to not less than eighty
percent (80%) of the full replacement value of the Building (excluding the land
and the footings, foundations and installations below grade). During the term
hereof, Landlord shall keep in force general liability insurance in the amount
and coverage as Landlord deans commercially reasonable but in no event less than
$1,000,000.00.

         13.      DAMAGE OR DESTRUCTION.


                                       15
<PAGE>

                  13.1 LOSS COVERED BY INSURANCE. If, at any time prior to the
expiration or termination of this Lease, the Premises or Building is wholly or
partially damaged or destroyed by a casualty, which loss to Landlord is (except
for any applicable deductible) fully covered by insurance maintained by Landlord
or for Landlord's benefit, which casualty renders the Premises totally or
partially inaccessible or unusable by Tenant in the ordinary conduct of Tenant's
business, then:

                           (a) REPAIRS WHICH CAN BE COMPLETED WITHIN SIX (6)
MONTHS. Within sixty (60) days of notice to Landlord of such damage or
destruction, Landlord shall provide Tenant with notice of its determination of
whether the damage or destruction can be repaired within six (6) months of such
damage or destruction without the payment of overtime or other premium. If all
repairs to such Premises or Building can, in Landlord's judgment, be completed
within six (6) months following the date of such damage or destruction without
the payment of overtime or other premiums, Landlord shall, at Landlord's
expense, repair the same to substantially their former condition to the extent
permitted by the then applicable codes, laws and regulations and this Lease
shall remain in full force and effect and a proportionate reduction of the Rent
shall be allowed Tenant for such portion of the Premises as shall be rendered
inaccessible or unusable to Tenant, and which is not used by Tenant, during the
period of time that such portion is unusable or inaccessible and not used by
Tenant.

                           (b) REPAIRS WHICH CANNOT BE COMPLETED WITHIN SIX (6)
MONTHS. If all such repairs to Building and Premises cannot, in Landlord's
judgment, be completed within six (6) months following the date of notice to
Landlord of such damage or destruction without the payment of overtime or other
premiums, Landlord shall notify Tenant of such determination and either Landlord
or Tenant may, at its option, upon written notice to the other party given
within thirty (30) days after Landlord's determination of how long it will take
to repair the occurrence of such damage or destruction, elect to terminate this
Lease as of the date of the occurrence of such damage or destruction. In the
event that neither Landlord nor Tenant elect to terminate the Lease in
accordance with the foregoing provisions, then Landlord shall, at Landlord's
expense, repair such damage or destruction to substantially their former
condition to the extent permitted by the then applicable codes, laws and
regulations and in such event, this Lease shall continue in full force and
affect but the Rent shall be proportionately reduced as hereinabove provided in
Section 13.1(a); provided, however, that if any such repair in not commenced by
Landlord within sixty (60) days after receipt at insurance proceeds or is not
substantially completed by Landlord within nine (9) months attar the occurrence
of such damage or destruction,, then in either such event Tenant may, at its
option, upon written notice to Landlord, elect to terminate this Lease as of the
date of the occurrence of such damage or destruction.

         15.      ASSIGNMENT AND SUBLETTING

                  15.1 LANDLORD'S CONSENT REQUIRED. Except as otherwise as
permitted in Section 15.9, Tenant shall not assign, transfer, mortgage, pledge,
hypothecate or encumber this Lease or any interest therein (each a "Transfer"),
and shall not sublet the Premises or any part thereof, without the prior written
consent of Landlord and any attempt to do so without such consent being first
had and obtained shall be wholly void and shall constitute a breach of this
Lease.


                                       16
<PAGE>

                  15.2     REASONABLE CONSENT.

                           (a) If Tenant complies with the following conditions,
Landlord shall not unreasonably withhold its consent to the subletting of the
Premises or any portion thereof or the assignment of this Lease. Tenant shall
submit in writing to Landlord (i) the name and legal composition of the proposed
subtenant or assignee; (ii) the nature of the business proposed to be carried on
in the Premises; (iii) the terms and provisions of the proposed sublease; (iv)
such reasonable financial information as Landlord may request concerning the
proposed subtenant or assignee; and (v) the form of the proposed sublease or
assignment. Within ten (10) business days after Landlord receives all such
information it shall notify Tenant whether it approves such assignment or
subletting or if it elects to proceed under Paragraph 15.8 below.

                           (b) The parties hereto agree and acknowledge that,
among other circumstances for which Landlord could reasonably withhold its
consent to a sublease or assignment, it shall be reasonable for Landlord to
withhold its consent where (i) Landlord reasonably disapproves of the
Transferee's reputation or creditworthiness or the character of the business to
be conducted by the Transferee at the Premises, (ii) the assignment or
subletting would increase the burden on the Building services or the number of
people occupying the Premises, or (iii) Landlord otherwise determines that the
assignment or sublease would have the effect of decreasing the value of the
Project or increasing the expenses associated with operating the Project.

                  15.3 EXCESS CONSIDERATION. If Landlord consents to the
assignment or sublease, Landlord shall be entitled to receive as additional Rent
hereunder one-half of any consideration paid by the Transferee for the
assignment or sublease and, in the case of a sublease, one-half of the excess of
the rent and other consideration payable by the subtenant over the amount of
Base Rent and Operating Cost Payments payable hereunder applicable to the
subleased space.

                  15.4 NO RELEASE OF TENANT. No Consent by Landlord to any
assignment or subletting by Tenant shall relieve Tenant of any obligation to be
performed by Tenant under this Lease, whether occurring before or after such
consent, assignment or subletting, and the Transferee shall be jointly and
severally liable with Tenant for the payment of Rent (or that portion applicable
to the subleased space in the case of a sublease) and for the performance of all
other terms and provisions of the Lease. The consent by Landlord to any
assignment or subletting shall not relieve Tenant and any such Transferee from
the obligation to obtain Landlord's express written consent to any subsequent
assignment or subletting. 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 or to be a consent to any assignment, subletting or other transfer.
consent to one assignment, subletting or other transfer shall not be deemed to
constitute consent to any subsequent assignment, subletting or other transfer.

                  15.5 ATTORNEYS' FEES. Tenant shall pay Landlord's reasonable
attorneys' fees incurred in connection with reviewing any proposed assignment or
sublease.

                  15.6 TRANSFER OF OWNERSHIP INTEREST. If Tenant is a business
entity, any direct or indirect transfer of 50 percent or more of the ownership
interest of the entity (whether all at one time or over the term of the Lease)
shall be deemed a Transfer.


                                       17
<PAGE>

                  15.7 EFFECTIVENESS OF TRANSFER. No permitted assignment by
Tenant shall be effective until landlord has received a counterpart of the
assignment and an instrument in which the assignee assumes all of Tenant's
obligations under this Lease arising on or after the date of assignment. The
voluntary, involuntary or other surrender of this Lease by Tenant, or a mutual
cancellation by Landlord and Tenant, shall not work a merger, and any such
surrender or cancellation shall, at the option of Landlord, either terminate all
or any existing subleases or operate as an assignment to landlord of any or all
of such subleases.

                  15.8 LANDLORD'S RIGHT TO SPACE. Except where excess
consideration is applicable as provided in Section 15.3 above, notwithstanding
any other provisions of this Paragraph 15 to the contrary, it Tenant notifies
Landlord that it desires to assign this Lease or sublet all (or any part) of the
Premises, Landlord, in lieu of consenting to such assignment or sublease, may
elect to terminate this Lease (in the case of an assignment or a sublease of the
entire Premises), or to terminate this Lease as it relates to the space proposed
to be subleased by Tenant (in the case of a sublease of less than the entire
Premises). In such event, this Lease (or portion thereof) will terminate on the
date the assignment or sublease was to be effective, and Landlord may lease such
space to any party, including the prospective Transferee identified by Tenant.

                  15.9 PERMITTED ASSIGNMENT. Notwithstanding any provision to
the contrary in this Section 15, Tenant shall not be required to obtain
Landlord's consent to an assignment of the Premises to a subsidiary or
affiliated company of Tenant or to a corporation into which or with which Tenant
may be merged or consolidated, or to a corporation which shall acquire all or
substantially all of the principal business of Tenant at the Premises.

         16.      SUBORDINATION

                  16.1 SUBORDINATION. Tenant agrees that upon delivery to it by
any mortgagee of the Building of a "non-disturbance letter" as defined in
Section 16. 4 below, this Lease at Landlord's option, shall be subject and
subordinate to a ground or underlying Lease which now exist or may hereafter be
executed affecting all or any part of the Project, and to the lion of any
mortgages or deeds of trust in any amount or amounts whatsoever now or hereafter
placed on or against the Land or building, Landlord's interest or estate
therein, or any ground or underlying lease, without the necessity of the
execution and delivery of any further instruments on the part of Tenant to
effectuate such subordination. if any mortgagee, trustee or ground lessor (each
a Holder) shall elect to have this Lease prior to the lien of its mortgage, deed
of trust or ground lease (an "Encumbrance"), and shall give written notice
thereof to Tenant, this Lease shall be deemed prior to such Encumbrance, whether
this Lease is dated prior to or subsequent to the date of said Encumbrance or
the date of the recording thereof.

                  16.2 SUBORDINATION AGREEMENTS. Tenant will execute and deliver
upon demand without charge therefor, such further instruments evidencing such
subordination of this Lease to such Encumbrances as may be required by Landlord.

                  16.3 ATTORNMENT. If this Project is transferred to any
purchaser pursuant to or in lieu of proceedings to enforce any Encumbrances and
this Lease is either prior to such Encumbrance or the Holder at its option
elects to have this Lease survive such transfer, Tenant


                                       18
<PAGE>

shall attorn to such purchaser and recognize such purchaser as the landlord
under this Lease, and this Lease shall continue as a direct lease between such
purchaser and Tenant.

                  16.4 NON-DISTURBANCE LETTER. Notwithstanding any provisions to
the contrary in section 16, Tenant's agreement to the provisions of said Section
is conditioned upon Tenant receiving a non-disturbance letter (as defined below)
from the holder of the existing mortgage or deed of trust or any future mortgage
or deed of trust an the Building. The "non-disturbance latter" shall be a letter
from the holder of any such mortgage or deed of trust to the affect that in the
event of a foreclosure or other action taken under any such security instrument
that this Lease and the rights of Tenant hereunder shall not be disturbed,
diminished or interfered with, but shall continue in full force and effect so
long as Tenant shall not be in default hereunder.

         17.      QUIET ENJOYMENT

                  Landlord covenants and agrees with Tenant that upon Tenant
paying the Rent and performing its other covenants and conditions under this
Lease, Tenant shall have the quiet possession of the Premises for the term of
this Lease as against any persons or entities lawfully claiming by, through or
under Landlord, subject, however, to the terms of this Lease and of any
Encumbrance.

         18.      DEFAULT; REMEDIES

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

                           (a) Tenant fails to pay Rent when due and such
failure continues for five (5) days after written notice thereof to Tenant;

                           (b) Tenant Transfers or attempts to Transfer this
Lease without complying with the provisions of Paragraph 15;

                           (c) Tenant fails to observe and perform any other
provision of this Lease to be observed or performed by Tenant, where such
failure continues for thirty (30) days after written notice thereof by Landlord
to Tenant; provided, however, that if the nature of the default is such that the
same cannot reasonably be cured within said thirty (30) day period, Tenant shall
not be deemed to be in default if Tenant shall within such period commence such
cure and thereafter diligently prosecute the same to completion;

                           (d) Tenant abandons the Premises; or

                           (e) The making by Tenant of any general assignment or
general arrangement for the benefit of creditors; the filing by or against
Tenant of a petition seeking relief under any law relating to bankruptcy
(unless, in the care of a petition filed against Tenant, the same is dismissed
within sixty (60) days); the appointment of a trustee or receiver to take
possession of substantially all of Tenant's assets located at the Premises or of
Tenant's interest in this Lease, whose possession is not restored to Tenant
within thirty (30) days; or the attachment, execution or other judicial seizure

<PAGE>

                  18.2 REMEDIES. Upon the occurrence of an Event of Default,
Landlord may, at any time thereafter exercise the following remedies, which
shall be in addition to any other rights or remedies now or hereafter available
to Landlord at law or in equity:

                           (a) Maintain this Lease in full force and effect and
recover Rent as it becomes due, without terminating Tenant's right to possession
irrespective of whether Tenant shall have abandoned the Premises. In the event
Landlord elects not to terminate the Lease, Landlord shall have the right to
attempt to relet the Premises at such rent and upon such conditions and for such
a term, and to do all acts necessary to maintain or preserve the Premises as
Landlord deems reasonable and necessary without being deemed to have elected to
terminate the Lease, including removal of all persons and property from the
Premises; such property may be removed and stored in a public warehouse or
elsewhere at the cost of and for the account of Tenant. In the event any such
reletting occurs, rents received by Landlord from such subletting shall be
applied (i) first, to the payment of the costs of maintaining, pre preserving
altering and preparing the Premises for subletting and other costs of
subletting, including but not limited to brokers' commissions, attorneys' fees
and expenses of removal of Tenant's personal property, trade fixtures,
alterations and leasehold improvements; (ii) second, to the payment of Rent then
due and payable; (iii) third, to the Payment of future Rent as the same may
become due and payable hereunder; and (iv) fourth, the balance, if any, shall be
paid to Tenant upon (but not before) expiration of the term of this Lease. If
the rents received by Landlord from such subletting, after application as
provided above, are insufficient in any month to pay the Rent due and payable
hereunder for such month, Tenant shall pay such deficiency to Landlord monthly
upon demand. Notwithstanding any such subletting for Tenant's account without
termination, Landlord may at any time thereafter, by written notice to Tenant,
elect to terminate this Lease by virtue of a previous Event of Default. During
the continuance of an Event of Default, for so long as Landlord does not
terminate Tenant's right to possession of the Premises, Landlord shall not
unreasonably withhold its consent to an assignment of this Lease or a sublease
of the Premises as set forth in Paragraph 3.5.2 -"Reasonable Consent".

                           (b) Terminate Tenant's right to possession of the
Premises at any time by written notice to Tenant, in which case Tenant shall
immediately surrender possession of the Promises to Landlord. Tenant expressly
acknowledges that in the absence of such written notice from Landlord,, no other
act of Landlord, including, but not limited to, its re-entry into the Premises,
its efforts to relet the Premises,, its reletting of the Premises for Tenant's
account, its storage of Tenant's personal property and trade fixtures,. its
acceptance of keys to the Promises from Tenant or its exercise of any other
rights and remedies under this Paragraph 18.2, shall constitute an acceptance of
Tenant's surrender of the Premises or constitute a termination of this Lease or
of Tenant's right to possession of the Promises. If Landlord terminates Tenant's
right to possession in writing,, Landlord shall be entitled to recover from
Tenant all damages as provided in California Civil Code Section 1951.2 or any
other applicable existing or future law, ordinance or regulation providing for
recovery of damages for such breach, including but not limited to the following:

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

                                    (2) The reasonable cost of removing Tenant's
alterations, trade fixtures and Above-Standard Improvements; plus


                                       20
<PAGE>

                                    (3) All unpaid Rent due or earned hereunder
prior to the date of termination, less the proceed of any reletting or any
rental received from subtenants prior to the date of termination applied as
provided in subsection (a) above, together with interest at the Default Rate, on
such sums from the date such Rent is due and payable until the date of the award
of damages; plus

                                    (4) The amount by which the Rent which would
be payable by Tenant hereunder, including operating Cost Payments from the date
of termination until the date of rim award of damages exceeds the amount of such
rental loss Tenant proves could have been reasonably avoided, together with
interest at the Default Rate on such sums from the date such Rent is due and
payable until the date of the award of damages; plus

                                    (5) The amount by which the Rent which would
be payable by Tenant hereunder, including Operating Cost Payments for the
remainder of the then term, after the date of the award of damages exceeds the
amount of such rental loss as Tenant proves could have boon reasonably avoided,
discounted at the discount rate published by the Federal Reserve Bank of San
Francisco for member banks at the time of the award plus one percent (1%); plus

                                    (6) Such other amounts in addition to or in
lieu of the foregoing as may be permitted from time to time by applicable law.

                           (c) During the continuance of an Event of Default,
Landlord may enter the Premises without terminating this Lease and remove all
Tenant In personal property, and trade fixtures from the Premises. If Landlord
removes such property from the Premises and stores it at Tenant's risk and
expense, and if Tenant fails to pay the cost of such removal and storage after
written demand therefor and/or to pay any Rent then due, after the property has
been stored for a period of thirty (30) days or more landlord may sell such
property at public or private sale, in the manner and at such times and places
as Landlord in its sole discretion deems commercially reasonable following
reasonable notice to Tenant of the time and place of such sale. The proceeds of
any such sale shall be applied first to the payment of the expenses for removal
and storage of the property, preparation for and conducting such sale, and
attorneys' fees and other legal expenses incurred by Landlord in connection
therewith, and the balance shall be applied as provided in subsection (a) above.

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

                           (d) Landlord may cure the Event of Default at
Tenant's expense. If Landlord pays any sum or incurs any expense in curing the
Event of Default, Tenant shall reimburse Landlord upon demand for the amount of
such payment or expense with interest at the Default Rate from the date the sun
is paid or the expense is incurred until Landlord is reimbursed by Tenant.


                                       21
<PAGE>

                  18.3 LATE CHARGES. Tenant hereby acknowledges that late
payment by Tenant to Landlord of Rent will cause Landlord to incur costs not
contemplated by this Lease, the exact amount of which will be extremely
difficult to ascertain. Such costs include, but are not limited to, processing
and accounting charges. Accordingly, if any installment of Base Rent or
operating costs Payments is not received by Landlord or Landlord's designee
within five (5) days after notice that such amount is past due, or if any
installment of other Rent is not received by Landlord or Landlord's designee on
or before the date such amount shall be dues, Tenant shall pay to Landlord a
late charge equal to seven percent (7%) of such overdue amount. The parties
hereby agree that such late charge represents a fair and reasonable estimate of
the costs Landlord will incur by reason of late payment by Tenant. Acceptance of
such late charge by Landlord shall in no event constitute a waiver of Tenant's
default with respect to such overdue amount nor prevent Landlord from exercising
any of the other rights and remedies granted hereunder. Notwithstanding the
foregoing, Tenant shall be allowed two (2) grace periods per annum.

                  18.4 INTEREST. In addition to the late charges referred to
above which are intended to defray Landlord's costs resulting from late
payments, any late payment of Rent shall, at Landlord's options, bear interest
from the due date of any such payment to the date the same in paid at the
Default Rate, provided, however, that if Landlord imposes a late charge on any
overdue payment, such overdue payment shall not begin to bear interest under
this Paragraph 18.4 until thirty (30) days after the due date thereof.

                  18.5 DEFAULT BY LANDLORD. Landlord shall not be in default
unless Landlord fails to perform obligations required of Landlord within a
reasonable time, but in no event later than thirty (30) days after written
notice by Tenant to Landlord and to any Holder whose name and address shall have
theretofore been furnished to Tenant in writing,, specifying that Landlord has
failed to perform such obligations; provided, however, that if the nature of
Landlord's obligation is such that more than thirty (30) days are required for
performance, then Landlord shall not be in default if Landlord commences
performance within such thirty (30) day period and thereafter diligently
prosecutes the same to completion.

         19.      PARKING

                  Tenant and Tenant's employees, invitees and customers shall
have the right to use the parking areas of the Building subject to such
regulations and charges as Landlord shall adopt from time to time, and subject
to the right of Landlord to restrict the use by Tenant and Tenant's
Representatives when in the sale judgment of Landlord such use is excessive for
the parking area in relationship to the reasonable use required by other
Tenants. Tenant will be allocated four (4) parking stalls free of charge for
every 1,000 rentable square feet contained in the Leased Premises.

         20.      RELOCATION PREMISES

                  (Intentionally Deleted)

         21.      MORTGAGEE PROTECTION.

                  Tenant agrees to give any Holder, by registered mail, a copy
of any notice of default served upon the Landlord, provided that prior to such
notice Tenant has been notified in


                                       22
<PAGE>

writing (by way of notice of assignment of rents and Lease or otherwise) of the
address of such Holder. If Landlord shall have failed to cure such default
within the time period act forth in Paragraph 18.5 the Holder shall have an
additional thirty (30) days within which to cure such default or if such default
cannot be cured within that rime, then such additional time as may be necessary
to cure such default (including the time necessary to foreclose or otherwise
terminate its Encumbrance, if necessary to affect such cure), and this Lease

Construction Rider are referred to herein as "Building Standard Materials".
All Suite Improvements above "Building Shell" (as described in schedule 1)
that utilize materials in addition to, substitution for or modification of
the Building standard Materials are called herein "Above-Standard Suite
Improvements".

          1.1.  PLANS. Interform has been retained by Tenant as the space
planner for the Premises.

                The Space Planner will prepare and deliver to Landlord for
its approval detailed plans and specifications sufficient to permit the
construction of the Suite Improvements by Landlord's contractor
("Construction Documents"). Landlord will provide Tenant and Space Planner
with any changes it requires to the Construction Documents. The Space Planner
will then revise the Construction Documents and resubmit them to Landlord for
its approval. The revised Construction Documents as approved by Landlord are
herein called the "Final Construction Documents." In all events Landlord must
have received Final Construction Documents, excluding finishes, cabinetry
details, sections and elevations, on or before August 31, 1993. The finishes,
cabinetry details, sections and elevations will be submitted no later than
September 7, 1993.

                If Tenant fails to cause the Space Planner to deliver any of
the foregoing items within the time periods provided above, or if Landlord
has not received Final Construction Documents and finishes, cabinetry
details, sections and elevations on or before the date set forth above,
Landlord may proceed to install Building Standard Materials in the Premises.
If Landlord does not elect to proceed with Building Standard Materials,
Tenant shall be responsible for all additional costs and delays arising from
its failure to so approve such items, as provided in Paragraph 1.4 below.

          1.2.  CONSTRUCTION. Upon Landlord's receipt of the Final
Construction Documents, Landlord shall proceed with reasonable diligence to
cause the Suite Improvements to be Substantially Completed on or prior to the

Lease entitled PREMISES.

          1.4.  TENANT DELAYS. Tenant shall be responsible for, and shall pay
to Landlord, any and all costs and expenses incurred by Landlord in
connection with any delay in the commencement or completion of any Suite
Improvements and any increase in the cost of Suite Improvements (whether or
not, Above-Standard) caused by (i) Tenant's failure to cause the Space
Planner to deliver the item described above within the rise periods required
above, (ii) the failure of Landlord to receive Final Construction Documents,
finishes, cabinetry details, sections and elevations on or before the dates
set forth above, (iii) Above-Standard Suite Improvements requested by Tenant,
(iv) any changes or modifications in the work requested by Tenant following
approval of the Final Construction Documents (v) Tenant's early entry onto
the Premises as described in Paragraph 3 hereof, or (vi) any other delay
requested or caused by Tenant (collectively, ".Tenant Delays").
Notwithstanding the foregoing, no Tenant Delay shall be deemed to have
occurred unless and until Landlord gives writ-ten notice to Tenant specifying
the action, inaction or occurrence constituting the Tenant Delay and the
number of days of such Tenant Delay ("Tenant Delay Notice"). Failure of
Tenant to deliver signed and approved Construction Documents to Landlord by
August 31, 1993, and or signed and approved drawings with finishes, cabinetry
details and sections on or before September 7, 1993, shall not require from
Landlord written notice, but shall automatically be considered a Tenant
Delay, and the number of days of such Tenant Delay shall equal the number of
days after August 31, 1993 and September 7, 1993, to and including the date
the signed and approved Construction Documents are given to Landlord.

     2.   COMMENCEMENT OF TERM . Upon Substantial Completion of the Suite
Improvements, Landlord shall deliver possession of the Premises to Tenant. If
any delays in Substantial Completion of the Suite Improvements are attributable
to Tenant Delays, Landlord will be deemed to have delivered the Premises and the
Commencement Date shall occur on the date on which Landlord would have
Substantially Completed the Premises and tendered the Premises to Tenant if
Substantial Completion had not been delayed by the number of days specified in
any and all Tenant Delay Notices given by Landlord, as described in Paragraph
1.4.

     3.   ACCESS TO PREMISES. Landlord, at its discretion, may allow Tenant or
Tenant's Representatives to enter the Premises prior to the Commencement Date to
permit Tenant to make the Premises ready for its use and occupancy; provided,
however, that prior to such entry of the Premises, Tenant shall provide evidence
reasonably satisfactory to Landlord that Tenant's insurance, as described in
Paragraph 12 of the Lease, shall be in effect as of the time of such entry. Such
permission may be revoked at any time upon twenty-four (24) hours notice, and
Tenant or its Representatives shall not interfere with Landlord or Landlord's
contractor in completing the Building or the Suite improvements. Tenant agrees
that Landlord shall not be liable in any way for any injury, loss or damage
which may occur to any of Tenant's property placed upon or installed in the

and Tenant shall be liable for all injury, loss or damage to persons or property
arising as a result of such entry of the Premises by Tenant or its
Representatives.
