Expiration Date shall be confirmed in writing by Landlord and Tenant within
fifteen (15) days after the Commencement Date.

3.2 OPTION TO EXTEND TERM:

(a) Option to Extend Term: As a material part of the consideration for
the execution of this Lease by Tenant, Tenant is hereby granted an option to
extend the Term for one (1) five (5) year period ("Extended Term") following the
Expiration Date, by giving Landlord written notice of Tenant's exercise of the
option and setting forth the agreed upon or arbitrator-determined Base Rent for
the Extended Term, ("Option Notice") at least nine (9) months before the

(b) Provisions Applicable to the Option: The option to extend set forth
in the preceding paragraph may be exercised by Tenant provided that, at the time
Landlord receives the Option Notice, Tenant is not in material default under
this Lease. Notwithstanding Section 3.2(a), if Tenant is in material default of
this Lease on the date Landlord receives the Option Notice, the Option Notice
shall be void and the Extended Term shall not commence unless Landlord notifies
the Tenant in writing within ten (10) days after receipt of the Option Notice
that the Option Notice is accepted and will operate to extend the Term. If
Tenant is in material default under this Lease on the date the Extended Term is
to commence and Tenant has not commenced any cure of such default within the
cure periods set forth in Section 12 below, then, in Landlord's sole election,
the Extended Term shall not commence and this Lease shall expire upon the
Expiration Date. Tenant shall in no event be deemed in default if curative
action has occurred pursuant to Section 12.

(c) Provisions Applicable To The Extended Term: The Extended Term shall
be upon the same terms and conditions as set forth in this Lease except as

condition at the Option Commencement Date.

(iv) If the Lease is extended, then "Term" as used in this Lease
shall include the Term and the Extended Term unless specifically provided to the
contrary.

(v) Within thirty (30) days after Tenant's delivery of an Option
Notice setting forth the agreed-upon Base Rent or arbitrator-determined Base
Rent for the Extended Term, the parties shall execute an amendment to this Lease
stating the new monthly Base Rent for the Extended Term, provided, however, that
the execution of such amendment shall not be a condition precedent to Tenant's
obligation to pay increased Base Rent.

accordance with the following procedure: Within forty (40) days after Tenant's
receipt of Landlord's notice, Landlord and Tenant shall jointly appoint an

arbitration rules of the American Arbitration Association. Such arbitrator and
alternate arbitrator shall be experienced with matters involving real estate
appraisals in the area in which the Premises are located. Concurrent with such
appointments, Landlord and Tenant shall each submit to such arbitrator their
respective determination of the Fair Market Rental Value and such arbitrator
shall select the one of such two submitted determinations that is closest to
such arbitrator's own appraisal of the Fair Market Rental Value. Such arbitrator
shall have no discretion to make any determination other than the selection of
either Landlord or Tenant's determination of Fair Market Rental Value. The cost
of such arbitrator shall be shared equally by Landlord and Tenant. Landlord and
Tenant shall each proceed expeditiously with the arbitration in order to permit
the arbitrator's decision to be issued at least Three hundred forty (340) days
prior to the Expiration Date. If the arbitrator's decision has not been received
by the Tenant and the Landlord three hundred forty (340) days prior to the
Expiration Date it shall be void unless the parties agree in writing otherwise,
and Landlord and Tenant shall each, three hundred and thirty (330) days prior to
the Expiration Date, submit to the alternate arbitrator their respective
determination of Fair Market Rental Value and the alternate arbitrator shall
select the one of such two submitted determinations that is closest to such
alternate arbitrator's own appraisal of the Fair Market

Rental Value. Such alternate arbitrator shall have no discretion to make any
determination other than the selection of either Landlord or Tenant's
determination of Fair Market Rental Value. The cost of such alternate arbitrator
shall be shared equally by Landlord and Tenant. Landlord and Tenant shall each
proceed expeditiously with the arbitration in order to permit the alternate
arbitrator's decision to be issued at least two hundred eighty (280) days prior
to the Expiration Date. In the event that the arbitrator's decision is not
received by Tenant on or before such date, Tenant shall nevertheless have a
period of ten (10) days following such receipt to determine whether to send the
Option Notice to Landlord, exercising Tenant's right to extend. If Tenant does
not so extend, the Term shall be extended by a number of days equal to Two
Hundred Seventy (270), minus the number of days remaining in the Term when the
Tenant's right to send the Option Notice expired, divided by two (2).

4.4 "FAIR MARKET RENTAL VALUE" shall mean the effective value on a monthly
basis of all expenditures for comparable office space being paid by willing,
comparable non-renewal tenants with a credit standing and financial stature
equivalent to Tenant, giving appropriate consideration to all relevant economic
terms and conditions of the Landlord/Tenant relationship, including without
limitation tenant improvement, refurbishment and other allowances, operating
expense stops or caps, leasing and other commissions (whether paid to
independent parties, to Landlord or to affiliates of Landlord), parking charges
or abatements, rental abatements, signing bonuses and similar cash or
cash-equivalent tenant concessions. For purposes of determination of Fair Market
Rental Value, other comparable space in the Project shall be considered the most
comparable space to the Premises and Landlord shall be obligated to furnish to
Tenant and any arbitrator copies of all leases of other space in the Project,
certified to contain all relevant information with regard to the economic
transaction between Landlord and the tenant thereunder. Other than the Project,
Landlord and Tenant acknowledge that the most comparable buildings to the
Building to be considered in determination of Fair Market Rental Value are set
forth in Exhibit "P", however other comparable buildings in the general area may
be considered.

4.5 SECURITY DEPOSIT AMOUNT: Upon the execution of this Lease, Tenant shall
deposit with Landlord cash or a check in the amount of the Security Deposit
Amount to secure the performance by Tenant of its obligations under this Lease,
including without limitation Tenant's obligations to (a) pay Rent, (b) repair
damages to the Premises caused by Tenant, Tenant's agent(s), employee(s),
officer(s) and/or independent contractor(s) of or retained by Tenant ("Tenant's
Representatives"), and/or Tenant's guests, visitors, customers, invitees and/or
licensees ("Tenant's Invitees"), (c) clean the Premises upon termination of this
Lease, and (d) remedy future defaults by Tenant in any obligation under this
Lease to restore, replace or return personal property installed or located in or
on the Premises including without limitation trade fixtures, furnishings,
equipment and inventory, signs, satellite dish ("Personal Property") or
appurtenances. If Tenant defaults under this Lease, including without limitation
a default described in the preceding sentence, Landlord may use the security
deposit to cure such defaults and to compensate Landlord for all or a portion of
Landlord's damage resulting from such defaults. Upon demand by Landlord, Tenant
shall promptly pay to Landlord a sum equal to the amount so used by Landlord so
as to replenish the Security Deposit Amount. Within thirty (30) days after the
Expiration Date, Option Expiration Date or earlier termination of this Lease,
Landlord shall deliver to Tenant, at Tenant's address, any portion of such
Security Deposit Amount not used by Landlord, together with a detailed statement
explaining how any portion of the Security Deposit Amount was used. Landlord may
commingle such Security Deposit Amount with Landlord's other funds and Landlord
shall not pay to Tenant interest on such Security Deposit Amount. In the event
of a bankruptcy or other insolvency or a debtor-creditor proceeding against or
by Tenant, the Security Deposit Amount shall be deemed applied first to the
payment of Rent and other amounts due Landlord for all periods prior to the date
of filing or instigating such proceedings. To the extent any debts, liabilities
and obligations of Tenant under this Lease have not been satisfied, Tenant shall
remain fully liable to Landlord for their payment and/or performance. Provided
that Tenant has not been in default under this Lease beyond the cure period set
forth in Section 12 below during the first sixty (60) months of the Term,
Landlord shall return to Tenant the Security Deposit Amount at the end of such
sixty (60) month period.

the contrary in the preceding sentence, "Real Property Taxes" shall not mean any
municipal, county, state, or federal income, franchise, estate, succession,
inheritance or transfer taxes of Landlord. If any Real Property Taxes are
assessed or collected on the basis of a fiscal period, a portion of which occurs
during the Term and the remainder of which occurs before or after the Term, then
the Real Property Taxes payable for such fiscal period shall be apportioned
between such periods based upon the number of days during such fiscal period

Square Footage to the Project Rentable Area.

6.2 ADJUSTMENTS TO COMMON AREA OPERATING EXPENSES: Common Area Operating
Expenses during the Term (including the Base Year) shall be "grossed up" ("Gross
Up") if the Project is less than ninety-five percent (95%) leased and occupied,
in accordance with reasonable and generally accepted accounting principles
consistently applied to reflect what Common Area Operating Expenses would have
been had the Project been ninety-five percent (95%) leased and occupied and
fully assessed for tax purposes as leased and occupied buildings. In no event
shall the Gross Up result in Landlord receiving payment or reimbursement from
Tenant for costs or expenses not actually incurred by Landlord.

6.3 RENT ADJUSTMENT: If Lease Expenses for any Lease Year are greater than
Lease Expenses for the Base Year (after the Gross Up of Common Area Operating
Expenses), Tenant shall pay such increase in Lease Expenses pursuant to this
Section 6.3. Landlord shall deliver to Tenant, at least thirty (30) days prior
to the commencement of each subsequent Lease Year during the Term, a written
statement ("Estimated Statement") setting forth Landlord's estimate of the
amount by which the Lease Expenses for the upcoming Lease Year will be greater
or less than the Lease Expenses for the Base Year (the "Lease Expenses
Difference"). If the Lease Expenses for the upcoming Lease Year are estimated to
be greater than the Lease Expenses for the Base Year, then Tenant shall pay to
Landlord, on the first day of each month during the Term, an amount ("Monthly
Payment") equal to one-twelfth (1/12th) of the Lease Expenses Difference, as
estimated by Landlord in the most recently delivered Estimated Statement.
Landlord may, at its election, no more than one (1) time during any Lease Year,
deliver to Tenant a revised Estimated Statement, revising Landlord's estimate of
the Lease Expenses, in accordance with Landlord's most current estimate. No
later than one hundred twenty (120) days after the end of each Lease Year,
Landlord shall deliver to Tenant a written statement ("Actual Statement")
setting forth the actual Lease Expenses Difference allocable to such Lease Year.
If the sum of Monthly Payments actually paid by Tenant during any Lease Year
exceeds the actual Lease Expenses Difference allocable to such Lease Year, then
such excess shall be refunded to Tenant within thirty (30) days after delivery
of the Actual Statement to Tenant. If Tenant has made Monthly Payments and the
sum of Monthly Payments actually paid by Tenant during any Lease Year is less
than the actual Lease Expenses Difference allocable to such Lease Year, then
Tenant shall, within thirty (30) days after receipt of the Actual Statement, pay
to Landlord the amount of such deficiency. The payment by Tenant of any Monthly
Payment or any year-end deficiency of Lease Expenses Difference shall not be
deemed a waiver of Tenant's right to contest Landlord's calculation of Lease
Expenses.

6.4 LEASE EXPENSES DIFFERENCE CAP: Notwithstanding anything to the contrary
in this Lease, Lease Expenses Difference shall not include more than one hundred
eight percent (108%) of Controllable Operating Expenses of the preceding Lease
Year, or in the case of the first Lease Year, the Base Year. "Controllable
Operating Expenses" shall mean landscaping maintenance, parking lot sweeping,
plumbing, Tri-Water System maintenance, janitorial services and supplies, trash
removal, security and life safety, pest control, elevator maintenance, parking
and walkways, locks and keys, window washing, lighting

maintenance, roof maintenance, painting and sealing, general maintenance, paving
maintenance, windows, doors and screens, signs, common area maintenance, and
management fees.

6.5 OPERATING EXPENSE RECORDS: Landlord shall maintain all operating
expense records for a period of five (5) years. Tenant or Tenant's
Representative shall have the right to inspect and photocopy any or all of the
operating expense records at the office of PacCor Management Company during
normal working hours upon twenty-four (24) hours written notice. Tenant shall
have the right to require an audit of Lease Expenses. In the event Tenant's
audit determines that Lease Expenses Difference for any Lease Year is overstated
by Twelve Thousand Five Hundred Dollars ($12,500.00) or more, then Landlord
shall pay for the cost of such audit unless the Actual Statement fairly
disclosed the facts underlying the overstatement. The $12,500.00 shall be
adjusted each Lease Year to reflect the increase, if any, in the cost of living
during the previous Lease Year by increasing the $12,500 by the percentage by
which the level of the Consumer Price Index (for all urban consumers in San
Diego areas as reported for the date of an audit pursuant to this Section 6.5 by
the Bureau of Labor Statistics of the United States Department of Labor) has
increased over the level as of the date of the execution of this Lease. Any
amounts of Lease Expenses Difference overpaid by Tenant shall be immediately
refunded or shall be credited against the Base Rent next due by Tenant.

for any other legally permitted use compatible with comparable office buildings

after Landlord delivers to Tenant a notice of such increases, the amount of such

expense, the Work shall comply with the requirements of the ADA and any similar
state and federal laws. If the Premises do not comply with the ADA or similar

at its sole cost be responsible for compliance with the ADA or other law(s).

7.4 HAZARDOUS WASTE OR NUISANCE: Landlord represents that to its knowledge

any other party or parties to cause any Hazardous Materials to be used,
generated, treated, stored, disposed of or released in, on or about the
Premises, except as allowed by law. Tenant shall indemnify, protect, defend by
counsel acceptable to Landlord, and hold Landlord and its successors, assigns
and mortgagees harmless from and against any and all claims, losses,
liabilities, costs and expenses, including all foreseeable and unforeseeable
consequential damages, except to the extent caused by Landlord's or Landlord's
Representative's negligence, willful misconduct or breach of obligations under
this Lease, directly or indirectly arising out of the use, generation,
treatment, storage, disposal, release or threatened release of Hazardous
Materials by Tenant or any party or parties claiming under Tenant of Hazardous
Materials at, on, beneath or from the Project based on the Comprehensive
Environmental Response, Compensation and Liability Act, 42 U.S.C. Sections 9601,
et seq., the Resource Conservation and Recovery Act, 42 U.S.C. Sections 6901, et

Control Act, Water Code Sections 13000, et seq., or any other federal, state or
local statute, law, regulation, ordinance or rule. Neither the written consent
by Landlord to the use, generation, storage or disposal of Hazardous Materials
nor the strict compliance by Tenant with all statutes, laws, ordinances, rules,
regulations and precautions pertaining to Hazardous Materials shall excuse
Tenant from Tenant's obligations pursuant to this Section 7.4. Tenant's
obligations pursuant to this Section 7.4 shall survive the termination of this
Lease. Tenant shall notify Landlord, as required by California Health & Safety
Code Section 25359.7, if Tenant knows or has reasonable cause to believe that
any Hazardous Material has come to be located on or beneath the Building. On or
before January 1, 1995, and each January 1 thereafter during the Term, Tenant
shall provide Landlord with a written list of all Hazardous Materials used,
generated, treated, stored, disposed of and released in, on or about the
Premises by Tenant during the prior calendar year and those Hazardous Materials

machinery, apparatus, or other appliance shall be used or operated in or on the
Premises that will in any manner injure the Premises or Project. If Tenant,
Tenant's Representatives or Tenant's Invitees cause damage to the Premises or

costs of such repair (to the extent that such costs exceed available insurance
proceeds) as Rent.

independent contractor(s) of or retained by Landlord ("Landlord's
Representatives") shall have the right to enter the Premises at all

reasonable times upon twenty-four (24) hour prior written notice (i) to
determine whether the Premises are in Good Condition (as defined in Section

to do any necessary maintenance or make any restoration to the Premises that the
Landlord has the right or obligation to perform, (iii) to serve, post, or keep
posted any notices required or allowed under this Lease, (iv) to show the

Project, and (v) to shore the foundations, footings, and walls of the Premises
and other improvements on the Real Property and to erect scaffolding and
protective barricades around and about the Premises or the Project, but not so
as to prevent entry to or use of the Premises and to do any other act or thing
necessary for the safety or preservation of the Premises or the Project if any
excavation or other construction is undertaken or is about to be undertaken on
any adjacent property or nearby street. Landlord shall have the right at any and
all times to enter the Premises for emergency purposes.

(b) Landlord shall not be liable for any inconvenience, disturbance,
loss of business, nuisance, or other damage arising out of Landlord's entry on
the Premises as provided in this Section 7.6, except damage resulting directly
from the negligent act or willful misconduct of Landlord or Landlord's
Representatives. No provision of this Lease shall be construed as obligating
Landlord to perform any repairs, alterations or decorations except as otherwise
expressly agreed in writing to be performed by Landlord. Landlord shall have the
right to run utility or other services and facilities through the Premises
whether to service the Premises or other premises, provided that the use of such
space does not have a materially adverse effect on Tenant's use and enjoyment of
the Premises. If during the last month of the Term, Tenant shall have removed
substantially all of its Personal Property and personnel from the Premises,
Landlord may enter the Premises and repair, alter and redecorate the same
without abatement of Base Rent or liability to Tenant and such acts shall have
no effect on this Lease. Any entry to the Premises obtained by Landlord pursuant
to this Section 7.6 shall not under any circumstances be construed or deemed to
be a forcible or unlawful entry into of the Premises, or an eviction of Tenant
from the Premises or any portion thereof. Tenant shall not be entitled to an
abatement or reduction of Base Rent because of the exercise by Landlord of any
rights under this Section 7.6. Landlord shall conduct its activities on the
Premises as allowed in this Section 7.6 in a manner that will cause as little
inconvenience, annoyance, or disturbance to Tenant as reasonably feasible.

7.7 SIGNS: Tenant shall have the right to place, construct and maintain one
or more signs, monuments, logos or emblems at the entrance to the Project, near
the top of the Building, on the directory, near the entrance to the Building
and/or on entrance doors of the Premises, as set forth in Exhibit "L" ("Signs").
Modifications to Signs shall be subject to Landlord's written approval, which
approval will not be unreasonably withheld. The design, construction and
maintenance of Signs shall be solely at Tenant's expense. Landlord makes no
representation with respect to Tenant's ability to obtain such approvals under
applicable laws and regulations or pursuant to that certain Declaration of
Covenants, Conditions and Restrictions for Unit No. 1 of Pacific Corporate
Center, dated May 14, 1985 and recorded as Instrument #85-169398 ("CC&R's";
Exhibit "K"). In any event, Signs shall comply with all laws, regulations,
CC&R's, and PID (Exhibit "N"). Tenant shall obtain any approvals required by
laws, regulations and CC&R's. All costs to remove all Signs upon the Expiration
Date, Option Expiration Date or earlier termination of the Lease shall be the
liability of Tenant.

7.8 PARKING: Subject to the terms of this Section 7.8 and so long as Tenant
is not in default under this Lease, Landlord grants to Tenant the right to the
non-exclusive use in common with other Project tenants of the parking lot
adjacent to and serving the Building of One Hundred Eighty Two (182) parking
spaces(except that there shall be reserved for the use of Tenant's visitors and
executives the twelve (12) parking spaces in front of the Building). Tenant's
use of the parking lot shall be subject to such reasonable rules which do not
favor other Project tenants to the detriment of Tenant, as Landlord may, in its
sole discretion, adopt from time to time with respect to use of the parking lot.
Landlord shall cooperate with Tenant, and shall take all reasonable steps
necessary, to ensure that Tenant and Tenant's Representatives and Tenant's
Invitees shall have access to all one hundred eighty-two (182) parking spaces to
which Tenant is entitled. Tenant shall not be charged for the use of the parking
lot unless the City of San Diego or other governmental entity after the
execution of this Lease assesses a tax, fee and/or excise on the parking of
motor vehicles in the parking lot, and then Tenant shall pay to Landlord that
portion of the tax, fee and/or excise based on Tenant's right to non-exclusive
parking of One Hundred Eighty Two (182) parking spaces, consisting of
approximately 50 percent of the Project parking lot capacity.

7.9 ALTERATIONS:

(a) Tenant shall not make any alterations, improvements, repairs,
additions, installations, or changes of any nature in or to the Premises
(individually and collectively, "Alterations") without Landlord's prior written
consent, which consent shall not be unreasonably withheld or delayed more than
ten (10) days after Landlord's receipt of Tenant's request for Landlord's
consent. If written consent is obtained from Landlord, any construction
undertaken by Tenant in or to the Premises shall comply with all the terms and
provisions of Sections 7.9(b) and 7.9(c). All Alterations made by Tenant shall
become the property of Landlord and a part of the realty and shall be
surrendered to Landlord upon the Expiration Date, Option Expiration Date or
sooner termination of the Lease, or, at Landlord's election but only in the
event that Landlord's approval of any such Alteration prior to installation
specified that such Alteration would be removed upon termination, and shall be
removed before the last day of the Term after receiving ninety (90) days prior
written notice from Landlord to Tenant or thirty (30) days after notice of
Landlord's election is given to Tenant in the event of earlier termination of
the Lease. All damage caused by such removal shall be repaired with all due
diligence by Tenant at its sole cost and expense.

(b) Tenant must utilize only bondable licensed contractors for any
Alterations proposed to be made in or to the Premises. Tenant shall promptly

as an additional insured, (C) Landlord's prior written approval of detailed
plans and specifications for such work which approval may not be unreasonably
withheld or delayed more than ten (10) days after Landlord's receipt of Tenant's
request for approval, and (D) with respect to any work estimated to cost more
the $50,000.00, procurement by Tenant or its contractor, if required by
Landlord, of both a performance and labor and materials payment bond (or a
single bond including such coverage) guaranteeing lien-free completion of the
work of improvements.

(ii) Notwithstanding Section 7.9(c)(i), all work on any
Alterations shall be performed in conformity with a valid permit and all other
applicable permits or licenses when and where required by cognizant government
authority or agency, copies of which shall be furnished to Landlord before the
work is commenced, and any work not acceptable to any governmental authority or
agency having or exercising jurisdiction over such work, or not reasonably
satisfactory to Landlord, shall be promptly corrected at Tenant's sole cost and
expense. Notwithstanding any failure by Landlord to object to any such work,
Landlord shall have no responsibility thereof either to Tenant or to third
parties.

(iii) Notwithstanding Section 7.9(c)(i), all work or any
Alterations shall be performed at such time and in such manner as Landlord may
schedule or designate. Tenant shall pay to Landlord, subject to Tenant's prior
written approval, any extraordinary costs incurred for monitoring any
substantial changes to the Premises.

(iv) Tenant shall reimburse Landlord subject to Tenant's prior
written approval, for any extraordinary expense actually incurred by Landlord by
reason of faulty work performed by Tenant or its contractors, or by reason of
delays caused by such work, or by reason of inadequate cleanup.

(v) Tenant or its contractors will in no event be allowed to
install plumbing, mechanical equipment, electrical wiring or fixtures,
acoustical or integrated ceilings, or partitions, unless such installation is
consistent with plans and specifications previously approved in writing by
Landlord.

(vi) All data processing, photocopying, copying and other special
electrical equipment shall have a separate duplex outlet and to the extent such
equipment requires electrical power in excess of that allotted to the Premises,
such equipment shall be installed only under the supervision of Landlord or its

electrical contractor. Tenant assumes the risk of all damage, costs, and expense
which is incurred by Landlord or other Premises tenants as the result of
Tenant's installation of electrical equipment in the Premises without the
supervision of Landlord or its electrical contractor. Tenant shall pay any
additional costs on account of any increased support to the floor load necessary
thereof or for any other equipment.

(vii) Tenant or its contractors shall, before the commencement of
any Alterations by Tenant in, on or around the Premises, give sufficient notice
thereof to Landlord for Landlord's preparation, posting and recordation of any
appropriate notices of non-responsibility as provided in California Civil Code
Section 3094 or any related, successor or similar provision of law. Within ten
(10) days after substantial completion of any Alterations or repairs, Tenant or
its contractor shall file for record in the Office of the County Recorder in and
for the county in which the Premises is located, a notice of completion as
permitted by law.

(viii) All Alterations shall conform to the then applicable
Building Standards. The Building Standards may be reasonably amended during the
Term of the Lease.

7.10 MECHANICS' LIEN: Tenant shall pay all costs for Alterations and other
construction done or caused to be done by it on the Premises. Tenant shall keep
the Premises free and clear of all mechanics' liens resulting from such
Alterations or other construction. Tenant shall have the right to contest the
correctness or validity of any such lien if, immediately on demand by Landlord,
Tenant procures and records a lien release bond, issued by a corporation
satisfactory to Landlord and authorized to issue surety bonds in California, in
an amount equal to one hundred fifty percent (150%) of the amount of the claim
of lien. The bond shall meet the requirements of California Civil Code Section
3143, shall indemnify Landlord against liability for such claim of lien and
shall hold the Project free from the effect of such claim of lien. In addition,
Landlord may require Tenant to pay Landlord's reasonable and necessary
attorneys' fees and costs in participating in such an action.

7.11 INDEMNITY AND EXEMPTION OF LANDLORD FROM LIABILITY:

(a) Except to the extent caused by the negligence or willful misconduct
of Landlord or Landlord's Representatives, Tenant shall indemnify, protect and
defend Landlord against all claims arising from (i) the use of the Premises by
Tenant, Tenant's Representatives and/or Tenant's Invitees, (ii) the conduct of
Tenant's business, (iii) any activity, work or things done, permitted or
suffered by Tenant or any of Tenant's Representatives in or about the Premises
or elsewhere, (iv) any breach or default in the performance of any obligation to
be performed by Tenant under this Lease, or (v) any negligence of Tenant,
Tenant's Representatives and/or Tenant's Invitees, and against all costs,
attorneys' fees, expenses and liabilities incurred in the defense of any such
claim and any action or proceeding brought on such claim. If any action or
proceeding is brought against Landlord by reason of any such claim, Tenant upon
written notice from Landlord shall defend such action or proceeding at Tenant's
sole cost by counsel satisfactory to Landlord. Tenant assumes all risk of damage
to property and injury to persons in, upon or about the Premises arising from
any cause, and Tenant waives all claims against Landlord in respect of such
damage or injury, except to the extent caused by Landlord's or Landlord's
Representative's sole and exclusive gross negligent acts or willful misconduct.
Tenant's obligations pursuant to this Section 7.11 shall survive the termination
of this Lease.

(b) Landlord shall not be liable for injury to Tenant's business or any
loss of income from such business or for damage or injury to the goods, wares,
merchandise, or other property or the person of Tenant, Tenant's Representatives
or Tenant's Invitees or any other persons in, upon or about the Premises,
whether such damage, loss or injury is caused by or results from criminal acts,
fire steam, electricity, gas, water or rain, or from the breakage, leakage,
obstruction or other defects of pipes, sprinklers, wires, appliances, plumbing,
air conditioning or lighting fixtures, or from any other cause, whether such
damage, loss or injury results from conditions arising upon the Premises or from
other sources or places and regardless of whether the cause of such damage, loss
or injury or the means of repairing such damages, loss or injury is inaccessible
to Tenant.

7.12 PREMISES CHANGES: This Lease shall not be affected or impaired by any
change to any part of the Project or any sidewalks, streets or improvements
nearby the Project, provided that access to the Premises, parking for the
Premises and Tenant's use of the Premises are not adversely materially affected
by such change.

7.13 SERVICES AND UTILITIES:

(a) Tri-Water System:

(i) Landlord has installed that portion of the water source heat
pump system set forth in the first and second paragraphs of Weather Engineering
letter to ▇▇▇▇ Construction Company dated April 6, 1993 attached as Exhibit "F"
and Landlord agrees to install a second circulating pump to operate alternately
with the existing pump and flush out all existing piping. The complete water
source heat pump system is described in Exhibit "F" ("Tri Water System").

(ii) The parties agree that the adequacy of the existing Tri-Water
System cannot be determined until the Final Space Plan (as defined in the Work
Letter) has been approved. If the Tri-Water System does not comply with Tenant's
specifications as reasonably determined by Tenant's consultant(s), then Landlord
shall pay a sum not to exceed Twenty Thousand Dollars ($20,000) to improve the
Tri-Water System, or to install an auxiliary system to the Tri-Water System. The
method chosen to comply with Tenant's specifications, if necessary, shall be
determined by Tenant and approved by Landlord, which approval shall not be
unreasonably withheld. Tenant shall pay all costs in excess of $20,000 in the
event the improvement of the Tri-Water System or installation of an auxiliary
system to the Tri-Water System costs more than Twenty Thousand Dollars
($20,000). The improved or auxiliary system shall become a part of the Building
for all purposes except as specifically set forth in this Section 7.13.

(iii) Tenant shall install as a component of the Work all portions
of the Tri-Water System within the Building which is set forth generally as
items 1 through 9 in Exhibit "F" and in that certain letter dated April 29, 1993
from ▇▇▇▇▇ Engineers (Exhibit "F1"). Tenant shall install as a component of Work
the improvement to the Tri-Water System or an auxiliary system if necessary.
Tenant shall obtain a twelve (12) month warranty on that portion of the
Tri-Water System or auxiliary system installed by Tenant. The warranty shall
provide that except for routine scheduled maintenance, all other maintenance and
repair work shall be at no cost to Landlord. The cost of the warranty, if any,
shall be at Tenant's expense. Tenant shall provide Landlord a copy of the
warranty upon Substantial Completion. Tenant shall install at Tenant's cost a
monitoring device to measure off-hours use of the Tri-Water System. Tenant shall
pay all costs of the Tri-Water System including any improvement or an auxiliary
system except as installed by Landlord as set forth in Section 7.13(a). Tenant
shall bear the financial responsibility of wear and tear on the Tri-Water System
by reason of use of such system during off-hours periods (other than 7:00 a.m.
to 7:00 p.m. Monday through Friday and 8:00 a.m. to 2:00 p.m. on Saturday) by
payment to Landlord, on a monthly basis, of the sum of One Dollar and Fifty
Cents ($1.50) per hour for each hour (or portion thereof) of off-hours use of
the Tri-Water System. Tenant shall provide Landlord written documentation to
support the off-hour use which shall accompany the monthly payment.

(b) Landlord's Responsibility: Landlord shall provide to the Building
telephone service and electrical service to the utilities equipment room in the
Builiding. Landlord shall install water line(s) to the Building at Landlord's
expense. Landlord shall furnish elevator service consisting of non-attended
automatic elevators, lighting replacement for exterior standard lights, daily
janitor services, and such other services and pursuant to the specifications set
forth on attached Exhibit "F". If Tenant uses heat generating machines or
equipment in the Premises which affect the temperature otherwise maintained

by the Tri-Water System for the Premises, Landlord reserves the right to install
supplementary air conditioning units in the Premises and the cost thereof,
including the cost of installation, operation and maintenance thereof, shall be
paid by Tenant to Landlord upon written demand by Landlord.

(c) Interruption of Services: In the event of any interruption of
service required to be provided by Landlord hereunder where such interruption is
caused by the negligence or willful misconduct of Landlord, Tenant shall be
entitled to abatement of Base Rent and Lease Expenses Difference in proportion
to the reasonable denial of use caused by the interruption, beginning on the
later of the third day after Tenant provides Landlord with notice of the
interruption or the actual date when Tenant stops using all or any affected
portion of the Premises because of the interruption, and continuing until the
restoration of the interrupted service. Notwithstanding the foregoing, Tenant
acknowledges that services to be supplied by Landlord hereunder may be
interrupted because of accidents, repairs, alterations, improvements or other
reasons beyond the reasonable control of Landlord. Except as set forth in the
next sentence of this Section 7.13 (c) no such interruption shall (i) be
considered an eviction or disturbance of Tenant's use and possession of the
Premises; (ii) make Landlord liable to Tenant for damages; (iii) ▇▇▇▇▇ Basic
Rent or Lease Expenses Difference or (iv) relieve Tenant from performing its
obligations hereunder. Notwithstanding the preceding sentence, if any essential
services (such as the Tri-Water System, passenger elevators, electricity or
water) supplied by Landlord are interrupted and the interruption does not result
from the negligence or willful misconduct of Landlord or Landlord's
Representatives, Tenant shall be entitled to an abatement of Base Rent and Lease
Expenses Difference beginning on the fourth consecutive business day of the
interruption and continuing until the interrupted services are restored.

(d) Tenant's Responsibility: As part of the Work, Tenant shall install
separate utility meters for electrical, gas and water service to the Premises
and any monitoring devices required to measure off-hours use of the Tri-Water
System. Tenant shall be responsible for the payment for all electrical, gas and
water service to the Premises and the Tri-Water System during the Term.

(e) Excessive Consumption: Tenant shall not connect any apparatus with
electric current except through existing electrical outlets in the Premises,
without Landlord's prior written consent which shall not be unreasonably
withheld. Tenant shall not consume water in excess of that usually and
reasonably furnished or supplied for the use of other tenants in the Project
using their premises as general office space, including limited lunchroom
facilities (as reasonably determined by Landlord), without first procuring the
written consent of Landlord, which will not be unreasonably withheld provided
that Tenant shall be responsible to pay for such excess use, and in the event of
consent, Landlord may cause to be installed a water meter for the Premises to
measure the amount of water consumed. The cost of any such meter and of its
installation, maintenance and repair shall be paid for by the Tenant and Tenant
agrees to pay Landlord promptly upon demand for all such water consumed as shown
by said meter, at the rates charged for such services by the local public
utility company plus any additional reasonable and necessary expense incurred by
Landlord in keeping account of the water so consumed. If a separate meter is not
installed, the excess cost for such water shall be established by an estimate
made by a utility company hired by Landlord at Tenant's expense.

7.14 RULES: Tenant and Tenant's Representatives shall observe faithfully
and comply strictly with the rules and regulations that are set forth in
attached Exhibit "E" and such other rules as Landlord may from time to time
reasonably adopt and disclose to Tenant for the Real Property and the Project
("Rules").

7.15 MAINTENANCE OBLIGATIONS:

(a) Tenant at its sole cost shall maintain (except to the extent
janitorial services are supplied by Landlord as set forth in the janitorial
specifications in Exhibit "J"), and repair, all in neat, clean, broom-clean and
good condition, with allowances for reasonable wear and tear ("Good Condition"),
all portions of the Premises, except those portions of the Premises to be
maintained by Landlord as expressly described in Section 7.15(b). Tenant shall
be liable for any damage to the Project resulting from the acts or omissions of
Tenant or Tenant's Representatives. If Tenant fails to maintain the Premises as
provided above, then after applicable periods of notice and periods to cure as
set forth in Section 12.1(b), Landlord shall have the right but not the
obligation to maintain the Premises and Tenant shall promptly reimburse Landlord
for Landlord's actual cost of such maintenance.

(b) Subject to Section 7.15(a), Landlord shall maintain, repair,
replace and repaint (i) the structural parts of the Building, which are limited
to foundations, bearing and exterior walls (excluding glass doors which are part
of Tenant's Premises), subflooring, and roof; (ii) the unexposed electrical,
plumbing, sewage systems and mechanical systems, elevators and elevator shafts
which are not part of the Work; (iii) windows and window frames, gutters and
downspouts on the Building; (iv) the Tri-Water System and any auxiliary system
to the Tri-Water System, if any, for the Building; and (v) that portion of the
Building not included as part of the Premises and the Common Area.

(c) Landlord's failure to perform its obligations set forth in Section
7.15(b) shall not release Tenant of its obligations under this Lease, including
without limitation Tenant's obligation to pay Rent. Tenant waives the provisions
of California Civil Code Sections 1941 and 1942 with respect to Landlord's
obligations for tenantability of the Premises and Tenant's right to make repairs
and deduct the expenses of such repairs from rent.

7.16 BUILDING SECURITY: Landlord shall supply building security systems and
services as set forth in Exhibit "G" and Exhibit "G1" or the equivalent as
reasonably determined by Landlord. Except for the service to be provided as set
forth in Exhibits "G" and "G1", Tenant acknowledges (a) that the monthly Base
Rent does not include the cost of additional security measures for any portion
of the Project, (b) that Landlord shall have no obligation to provide any such
additional security measures, and (c) that Landlord has made no representation
to Tenant regarding the safety or security of the Project. Tenant assumes all
responsibility for the security and safety of Tenant and/or Tenant's Invitees
and Tenant's employees. Except to the extent caused by the negligence or
intentional misconduct of Landlord or Landlord's Representatives, Tenant
releases Landlord from all claims for damage, loss or injury to Tenant, Tenant's
Invitees, Tenant's employees and/or to Tenant's Personal Property, even if such
damage, loss or injury is caused by or results from the criminal or negligent
acts of third parties. Landlord shall have no duty to warn Tenant of any
criminal acts or dangerous conduct that has occurred in or near the Premises,
unless Landlord has received written notice of such acts or conduct.

7.17 TENANT TO PAY PERSONAL PROPERTY TAXES: Tenant shall pay before
delinquent all taxes, assessments, license fees, and other charges levied or
assessed against, or based upon the value of Tenant's Personal Property
("Personal Property Taxes") that become payable during the Term. On written
demand by Landlord, Tenant shall furnish Landlord with written satisfactory
evidence of such payments. If any Personal Property Taxes are levied against
Landlord or Landlord's property, or if the assessed value of the Project is
increased by the inclusion of a value placed on Tenant's Personal Property, and
if Landlord pays such Personal Property Taxes or any taxes based on the
increased assessments caused by such Tenant's Personal Property, then Tenant, on
demand, shall immediately reimburse Landlord for the sum of the Personal
Property Taxes so levied against Landlord, or the proportion of taxes resulting
from such increase in Landlord's assessment. Landlord shall have the right to
pay such Personal Property Taxes or such proportion, and receive such
reimbursement, regardless of the validity of the levy.

SECTION 8
INSURANCE

8.1 TENANT'S INSURANCE:

(a) Public Liability and Property Damage Insurance: Tenant shall
procure at its sole cost and expense and keep in effect from the date of this
Lease at all times until the end of the Term, comprehensive general liability
insurance insuring against liability of Tenant, Tenant's Representatives,
Landlord, and Landlord's Representatives, arising out of or in connection with
Tenant's use or occupancy of the Premises or any part thereof, or the Project by
Tenant or Tenant's Representative. Such insurance shall include contractual
liability insurance coverage insuring Tenant's indemnity obligations under this
Lease. Such coverage shall have a minimum combined single limit of liability of
not less than $1,000,000 with a minimum general aggregate limit of
$1,000,000.00. Such policies shall be written to apply to property damage,
bodily injury, personal injury, premises medical payments, fire legal liability,
general liability and other covered losses, however occasioned, occurring during
the policy term, naming the Landlord and Landlord's lender as additional
insureds, providing that such coverage shall be primary and that any insurance
maintained by Landlord shall be excess insurance only. Such coverage shall also
(i) delete any employee exclusion on personal injury coverage; (ii) include
employees as insureds; (iii) include liquor liability and (iv) include
employer's automobile non-ownership liability. All such insurance shall provide
for severability of interests or contain a cross-liability endorsement and shall
provide that an act or omission of one of the named

insureds shall not reduce or avoid coverage to the other named insureds; and
shall afford coverage for all claims based on acts, omissions, injury and
damage, which claims occurred or arose (or the onset of which occurred or arose)
in whole or in part during the policy period.

(b) Automobile Liability Insurance: Tenant shall procure at its sole
cost and expense and keep in effect from the date of this Lease at all times
until the end of the Term, if applicable, Comprehensive Automobile Liability
insurance covering owned, non-owned and hired vehicles. Such coverage shall have
a minimum combined single limit of liability of not less than $1,000,000.

(c) Workers Compensation Insurance: Tenant shall, if applicable,
maintain Workers' Compensation insurance in accordance with California law, and
employer's liability insurance with a limit of not less than $1,000,000.
Workers' Compensation insurance shall be endorsed to waive the insurer's right
of subrogation against Landlord.

(d) Business Personal Property and Loss of Income Insurance: Tenant
shall, if applicable, maintain business personal property insurance to pay for
damage to or destruction of the Tenant's property from damage to or destruction
of the Premises. Such insurance shall insure against losses on an "all-risk"
type policy to the extent of at least one hundred percent (100%) of the full
replacement value of business personal property.

(e) Maintaining Insurance: If Tenant fails during the Term to maintain
any insurance required to be maintained by Tenant under this Lease, then
Landlord may, at its option and in addition to Landlord's other remedies in the
event of default by Tenant, arrange for any such insurance, and Tenant shall
reimburse Landlord for any premiums for any such insurance within five (5)
business days after Tenant receives a copy of the premium notice. If such
premiums are allocable to a period, a portion of which occurs during the Term
and the remainder of which occurs before or after the Term, then such premiums
shall be apportioned between Landlord and Tenant based upon the number of days
during such period that occurred during the Term and the number of days that
occurred before or after the Term, such that Tenant pays for the premiums that
are allocable to the period during the Term. Insurance required to be maintained
by Tenant under this Lease (i) shall be issued as a primary policy by insurance
companies authorized to do business in the State of California with a Best's
rating of a least "A" and a Best's financial size category rating of at least
"VIII", as set forth in the most current edition of Best's insurance reports or
such higher rating as may be required by Landlord's lender, (ii) shall name the
Additional Insureds as additional named insureds, (iii) shall constitute
"occurrence" based coverage, without provision for subsequent conversion to
"claims" based coverage, and (iv) shall not be cancelable or subject to
reduction of coverage or other modification except after thirty (30) days' prior
written notice to Landlord and any lender. Tenant shall, at least thirty (30)
days prior to the expiration of any such policy, furnish Landlord with a renewal
or binder of such policy. Tenant shall, upon request from Landlord, promptly
deliver to Landlord copies of such policy or policies or certificates evidencing
the existence and amounts of such insurance together with evidence of payment of
premiums. Any policy required to be maintained by Landlord or Tenant under this
Lease may be maintained under a so-called "blanket policy" insuring other
parties and/or other locations, so long as the amount of insurance and type of
coverage required to be provided under this Lease is not thereby diminished,
changed or adversely affected.

(f) All insurance coverage, terms and conditions described in this
Section 8.1 shall be evidenced by a Certificate of Insurance issued to Landlord.
A copy of all insurance policies issued to Tenant during the Term shall be
forwarded to Landlord within sixty (60) days after the Commencement Date.

(g) If at any time during the Term the amount or coverage of insurance
which Tenant is required to carry under this Section 8.1 is, in Landlord's
reasonable judgment, materially less than that amount or type of insurance
coverage typically carried by owners or tenants of properties located in San
Diego, California, which are similar in size and used for similar purposes as
the Premises, Landlord shall have the right to require Tenant to increase the
amount or change the types of insurance coverage required under this Section
8.1.

8.2 Landlord's Insurance: Landlord shall, at its expense, maintain in
effect at all times during the Term: a policy or policies of "all risk" fire,
general liability and extended coverage insurance, including at least six (6)
months rental interruption insurance, with vandalism and malicious mischief
endorsements, coverage with respect to increased costs due to building
ordinances, demolition coverage, boiler and machinery insurance, sprinkler
leakage coverage, in each case to the extent of at least one hundred

percent (100%) of the full replacement value of the Building and Adjacent
Building and any future building on the Project. Landlord shall notify Tenant of
Landlord's obtaining any such insurance. If Landlord fails during the Term to
maintain any insurance required to be maintained by Landlord under this Lease,
then Tenant may, at its election, arrange for any such insurance, and Tenant may
require that Landlord reimburse Tenant for any premiums for any such insurance
within five (5) days after Landlord or Tenant's receipt of the premium notice.
Insurance required to be maintained by Landlord under this Lease (a) shall be
issued as a primary policy by insurance companies authorized to do business in
California with a Best's Rating of at least "A" and a Best's Financial Size
Category rating of at least "VIII," as set forth in the most current edition of
"Best's Insurance Reports," or such higher rating as may be required by any
lender, (b) shall name Tenant and any lender or other party as Tenant may elect
as additional named insureds, (c) shall constitute "occurrence" based coverage,
without provision for subsequent conversion to "claims" based coverage, and (d)
shall not be cancelable or subject to reduction of coverage or other
modification except after thirty (30) days' prior written notice to Tenant and
any lender. Landlord shall, at least thirty (30) days prior to the expiration of
each such policy, furnish Tenant with a renewal or "binder" of such policy.
Landlord shall, upon request from Tenant, promptly deliver to Tenant copies of
such policy or policies or certificates evidencing the existence and amounts of
such insurance together with evidence of payment of premiums. The premiums,
costs and expenses and deductibles of and/or with respect to any such insurance
shall be included in the Building Operating Expenses. Landlord shall not
increase the amount or types of insurance coverage beyond that which was in
place during the Base Year, other than reasonable increases to reflect inflation
or an increase in value of the insured property. Landlord has set forth on
Exhibit "O" quotes for any insurance coverage Landlord may reasonably obtain in
the future. If Landlord subsequently obtains in any Lease Year insurance
coverage which is set forth on Exhibit "O", then Lease Expenses for the Base
Year shall include the insurance quotes on Exhibit "O" and Lease Expenses for
the Lease Year shall include the cost of insurance to the extent increases over
the quotes are a result of reasonable increases for inflation or the value of
the insured property.

SECTION 9
DESTRUCTION

9.1 RISK COVERED BY INSURANCE:

(a) If during the Term the Premises is totally or partially destroyed,
rendering the Premises totally or partially inaccessible or unusable, Landlord
shall, subject to Sections 9.1(b) and 9.1(c), restore the Premises to
substantially the same condition as it was in immediately before the
destruction. Such destruction shall not terminate this Lease. If, however,
then-existing laws do not permit such restoration, Landlord may terminate this
Lease by giving written notice to Tenant.

(b) If Landlord determines that the cost of such restoration exceeds
the amount of proceeds received by Landlord from any insurance maintained by
Landlord, then Landlord may elect to terminate this Lease by giving notice to
Tenant within sixty (60) days after such destruction or within sixty (60) days
after Landlord's receipt of such proceeds, whichever is later. If Landlord gives
such notice of termination, then this Lease shall terminate as of forty-five
(45) days after Landlord's notice of termination, unless Tenant provides
Landlord with written notice of its election to pay the amount by which the cost
of such restoration exceeds the amount of proceeds received by Landlord ("Notice
To Restore"), in which event this Lease shall remain in full force and effect.
Tenant shall have thirty (30) days after Notice To Restore to pay the excess
cost of restoration either to Landlord or to an escrow account to be used for
restoration.

(c) Within thirty (30) days after such destruction, Landlord shall
notify Tenant in writing whether or not, based on Landlord's determination, the
Premises can be restored within six (6) months after the date of such
destruction. If such restoration cannot be completed within such six (6) month
period, either party may terminate this Lease by giving written notice to the
other party within twenty (20) days after the date of Landlord's written notice.
If Landlord determines that the Premises can be restored within such six (6)
month period and neither party terminates this Lease pursuant to this Section 9,
Landlord shall use its reasonable efforts to restore the Premises within such
six (6) month period to substantially the same condition as it was in
immediately before the destruction.

9.2 ABATEMENT OR REDUCTION OF RENT: In case of any destruction to the
Premises, all obligations of Tenant under this Lease shall remain in effect,
except that Base Rent and Lease Expenses Difference shall be abated or reduced,
between the date of such destruction and the date of completion of restoration,
by

the ratio of (a) the area of the Premises rendered unusable or inaccessible by
the destruction to (b) the area of the Premises prior to such destruction.

9.3 LOSS DURING LAST PART OF TERM OR EXCEEDING TWENTY-FIVE PERCENT (25%) OF
REPLACEMENT VALUE: Not withstanding any other provision of this Lease, if any
destruction to the Premises occurs during the last year of the Term, or if, at
any time during the Term, there is any destruction to the Premises that exceeds
twenty-five percent (25%) of the then replacement value of the Premises,
Landlord or Tenant may terminate this Lease by giving written notice to the
other not more than thirty (30) days after such destruction, in which case (a)
neither Landlord nor Tenant shall have any obligation to restore the Premises,
(b) Landlord shall retain all insurance proceeds relating to such destruction
except for insurance proceeds relating to the loss of or damage to Tenant's
Personal Property or loss of business, and (c) this Lease shall terminate as of
thirty (30) days after such notice of termination.

9.4 LIMITATION ON LANDLORD'S RESTORATION OBLIGATION: If Landlord is
required or elects to restore the Premises as provided in Section 9.1, Landlord
shall not be required to restore any of Tenant's Alterations which were
constructed without Landlord's written consent or any of Tenant's Personal
Property, unless they are an integral part of the Premises and specifically
covered by insurance proceeds received by Landlord, such excluded items being
the sole responsibility of Tenant to restore.

SECTION 10
CONDEMNATION

10.1 DEFINITIONS: For purposes of this Lease, the following definitions
shall apply:

(a) "Condemnation" shall mean the exercise of any governmental power,
whether by legal proceedings or otherwise, by a Condemnor (as defined below) or
a voluntary sale or transfer by Landlord to any Condemnor, either under threat
of condemnation or while legal proceedings for condemnation are pending;

(b) "Date of Taking" shall mean the date the Condemnor has a right to
possession of the property being condemned;

(c) "Award" shall mean all compensation, sums or anything of value
awarded, paid, or received on a total or partial Condemnation of the Project;
and

(d) "Condemnor" shall mean any public or quasi-public authority, or
private corporation or individual, having the power of Condemnation.

10.2 GOVERNED BY LEASE: If during the Term, or during the period of time
between the execution of this Lease and the Commencement Date, there is any
taking of all or any part of the Project or any interest in this Lease by
Condemnation, the rights and obligations of Landlord and Tenant shall be
determined pursuant to this Section 10.

10.3 TOTAL TAKING: If the Premises are totally taken or more than thirty
percent (30%) of the available parking area is taken by Condemnation, this Lease
shall terminate on the Date of Taking.

10.4 PARTIAL TAKING: If any portion, but not all, of the Premises is taken
by Condemnation, this Lease shall remain in effect, except that Tenant may elect
to terminate this Lease if the remaining portion of the Premises is rendered
unsuitable for Tenant's continued use of the Premises. If Tenant elects to so
terminate this Lease, Tenant must exercise its right to terminate by giving
notice to Landlord within sixty (60) days after the date that the nature and the
extent of the taking have been determined ("Determination Date"), which notice
shall set forth the date of termination. Such termination date shall not be
earlier than thirty (30) days nor later than ninety (90) days after Tenant has
notified Landlord of its election to terminate; except that this Lease shall
terminate on the Date of Taking if the Date of Taking falls on a date before the
date of termination as designated by Tenant. If Tenant does not so notify
Landlord within sixty (60) days after the Determination Date, all obligations of
Tenant under this Lease shall remain in effect, except that Base Rent shall be
reduced by the ratio of (a) the area of the Premises taken to (b) the area of
the Premises immediately prior to the Date of Taking.

10.5 AWARD: The Award shall belong to and be paid to Landlord, Tenant shall
have no right to any part of the Award, and Tenant assigns to Landlord all of
Tenant's right, title and interest in and to any part of the Award, except that
Tenant shall receive from the Award an amount equal to the value of Tenant's
leasehold interest and any sum paid expressly to Tenant from the Condemnor for
relocation, the cost of tenant improvements which were paid for by Tenant and
not part of the Tenant Improvement Allowance, the value of Alterations and loss
of goodwill.

10.6 TEMPORARY TAKING: The taking of the Premises or any part of the
Premises by military or other public authorities shall constitute a taking of
the Premises by Condemnation only when the use and occupancy by the taking
authority is continued for longer than one hundred eighty (180) consecutive
days. During the one hundred eighty (180) day period, all obligations of Tenant
under this Lease shall remain in effect, except that Base Rent shall be abated
or reduced during such period of taking by the ratio of (a) the area of the
Premises taken to (b) the area of the Premises immediately prior to the Date of
Taking, and Landlord shall be entitled to any Award related to such taking.

10.7 WAIVER OF STATUTE: Landlord and Tenant waive the provision of
California Code of Civil Procedure Section 1265.130 allowing Landlord or Tenant
to petition the superior court to terminate this Lease in the event of a partial
taking of the Premises.

SECTION 11
ASSIGNMENT AND SUBLETTING

11.1 ASSIGNMENT:

(a) Tenant shall not assign, enter into a license or concession
agreement for, hypothecate or otherwise divest itself of this Lease or any of
its rights under this Lease or permit any third party or parties other than
Tenant to occupy the Premises or any portion thereof without Landlord's prior
written consent, which consent shall not be unreasonably withheld, but is
subject to the terms and conditions contained in this Section 11.

(b) For purposes of this Lease, each of the following events shall be
deemed to constitute an assignment of this Lease:

(i) any assignment or transfer of this Lease, or any interest in
this Lease, voluntarily, involuntarily, by operation of law or otherwise;

(ii) any mortgage, hypothecation, pledge, or collateral assignment
of this Lease or any interest in this Lease;

(iii) any sale, transfer, grant of concessions or licenses, or
other disposition of this Lease, any interest in this Lease or all or any
portion of the Premises;

(iv) any assignment, transfer, disposition, sale, or acquisition
of a controlling interest in Tenant to or by any person, entity, or group of
related persons or affiliated entities, whether in a single transaction or in a
series of related or unrelated transactions ("Change of Control"). For purposes
of this Lease a "Change of Control" shall mean a change in the identity of the
person or persons exercising, or who may exercise, effective control of Tenant,
unless such change results from either (A) the acquisition of Tenant by a
publicly traded company, (B) the trading of shares listed on a recognized
national securities exchange, or (C) the transfer of interests in Tenant for
purposes of estate or tax planning; and

(v) any issuance of an interest or interests in Tenant (whether
stock, partnership interests, or otherwise) to any person, entity, or group of
related persons or affiliated entities, whether in a single transaction or in a
series of related or unrelated transactions, which results in Change of Control.

(c) At least fifteen (15) days prior to entering into any assignment of
this Lease of all or any portion of the Premises, Tenant shall submit to
Landlord the form of such proposed assignment, and a written notice ("Tenant's
Notice") setting forth in reasonable detail (i) the name and address of the
proposed assignee, (ii) the terms and conditions of the proposed assignment,
including without limitation the proposed effective date of the assignment,
which shall be at least thirty (30) days after Tenant's Notice is given, (iii)
the nature and character of the business of the proposed assignee, and (iv)
current banking, financial, and other credit information, including prior year's
federal tax return, if available, (all of which information Landlord agrees to
treat as strictly confidential and not disclose or disseminate to third parties)
relating to the proposed assignee, in reasonably sufficient detail, to enable
Landlord to determine the proposed assignee's financial responsibility.

(d) Within thirty (30) days after Landlord's receipt of Tenant's Notice
and the form of assignment, Landlord shall notify Tenant whether Landlord has
consented to the proposed assignment. Any consent granted by Landlord in any
instance shall not constitute a consent with respect to any other instance or
request. If Landlord consents to any proposed assignment and Tenant fails to
consummate such assignment within one hundred eighty (180) days after such
consent, then such consent shall be deemed withdrawn and Tenant shall be
required again to comply with this Section 11 before assigning this Lease or any
portion of the Premises.

(e) Landlord shall not have unreasonably withheld its consent with
respect to any assignment if Landlord shall not have received Tenant's Notice as
provided above, nor if (i) the nature and character of the proposed assignee and
the proposed use and occupancy of the Premises by the proposed assignee is not
in keeping with the dignity and character of the Premises and the surrounding
area, (ii) the proposed assignment will result in the diminution of the value or
marketability of the Premises, (iii) upon review of the information furnished in
Tenant's Notice, Landlord is not satisfied that the proposed assignee's use of
the Premises will not conflict with other uses in the Premises. Tenant
acknowledges that Tenant's Notice shall be ineffective if Tenant is in material
default with respect to any provision under this Lease.

11.2 SUBLEASE: If Tenant is not in default of the Lease, Tenant may
sublease all or a portion of the Premises upon Landlord's prior written consent,
which consent shall not be unreasonably withheld. Any sublease of all or a
portion of the Premises shall be in accordance with the terms and conditions of
this Section 11 and all other applicable terms and conditions of this Lease.
Tenant's request to sublease all or a portion of the Premises shall be in the
form of the Tenant's Notice as set forth in Section 11.1(c).

(a) Any sublease of all or any portion of the Premises must contain the
following provisions, which provisions, whether contained in such sublease nor
not, shall apply to such sublessee:

(i) Such sublease shall be subject and subordinate to all of the
provisions of this Lease (including all exhibits) and any subsequent amendments
of this Lease;

(ii) At Landlord's option, in the event of cancellation or
termination of this Lease for any reason or the surrender of this Lease, whether
voluntarily, involuntarily, or by operation of law, prior to the expiration of
such sublease, the subtenant shall make full and complete attornment to Landlord
for the balance of the term of such sublease, provided that Landlord agrees in
writing not to disturb subtenant's right to occupy the subleased area as long as
such sublessee is in compliance with its obligations under such sublease. The
subtenant shall execute and deliver to Landlord an agreement of attornment
satisfactory to Landlord within five (5) days after requested by Landlord; and

(iii) No sublessee shall be permitted to further sublet all or any
portion of the subleased space without Landlord's prior written consent.

(b) Tenant shall submit all subleases to Landlord prior to execution
for Landlord's review and approval, which shall not be unreasonably withheld or
delayed more than fourteen (14) days after Landlord's receipt of any sublease.

11.3 TENANT AND ASSIGNEE OR SUBLESSEE FULLY LIABLE: No assignment of this
Lease nor any sublease of all or any portion of the Premises shall release or
discharge Tenant from any liability, whether past, present, or future, under
this Lease and Tenant shall continue to remain primarily liable under this
Lease. The assignee of any assignment of this Lease, and the sublessee of any
sublease of all or any portion of the Premises, shall execute, acknowledge, and
deliver to Landlord an agreement satisfactory to Landlord in which the assignee
or sublessee assumes and agrees to be bound by all of the provisions of this
Lease.

11.4 ASSIGNMENT OF RENTS: Tenant irrevocably assigns to Landlord, as
security for Tenant's obligations under this Lease, all rent from any subletting
of all or any portion of the Premises, and Landlord, as assignee and as special
attorney-in-fact for Tenant, or a receiver for Tenant appointed on Landlord's
application, may collect such rent and apply it toward Tenant's obligations
under this Lease, except that, unless Tenant defaults under this Lease, Tenant
shall have the right to collect such rent.

11.5 SUBLEASE ASSIGNMENT RIGHT: Landlord and Tenant shall share equally any
"Premium" (as defined below) arising from the sublease of any portion of the
Premises to any entity which is not a subsidiary of Tenant. For purposes of this
paragraph "Premium" shall mean all sums received by Tenant under the sublease
which exceeds the Rent attributable to the subleased portion of the Premises,
after deducting (a) all reasonable expenses of Tenant incurred in connection
with such sublease amortized on a straight line basis over the initial term of
the sublease, including without limitation legal costs, brokerage commissions,
rent abatement and other concessions, lease takeover, subtenant improvement
costs, the unamortized value of Tenant's leasehold improvements, downtime, and
cash payments, (b) any utility costs paid by Tenant which is attributable to
such subleased premises, and (c) any Additional Rent paid by Tenant which is
attributable to such subleased premises. The determination of Base Rent
attributable to the subleased portion of the Premises shall be made on the basis
of the ratio of the rentable square footage in the subleased portion to the
Rentable Square Footage.

SECTION 12
DEFAULT AND REMEDIES

12.1 DEFAULT: The occurrence of any of the following shall constitute a
material default and breach of this Lease by Tenant:

(a) the failure by Tenant to pay Rent as and when due, where such
failure shall continue for a period of three (3) business days after written
notice of such failure from Landlord to Tenant. In the event that Landlord
serves Tenant with a Notice to Pay Rent or Quit pursuant to applicable statutes
set forth in California Code of Civil Procedure, such Notice to Pay Rent or Quit
shall also constitute the notice of such failure;

(b) the failure by Tenant to observe or perform any of the provisions
of this Lease to be observed or performed by Tenant, other than described in
Section 12.1(a), where such failure shall continue for a period of thirty (30)
days after written notice of such failure from Landlord to Tenant; provided,
however, that if the nature of Tenant's default is such that more than thirty
(30) days are required for its cure, then Tenant shall not be deemed to be in
default if Tenant commenced such cure within such thirty (30) day period and
thereafter diligently prosecutes such cure to completion within sixty (60) days
after Landlord's written notice; or

(c) the making by Tenant of any general arrangement or assignment for
the benefit of creditors; Tenant's becoming bankrupt, insolvent or a "debtor" as
defined in 11 U.S.C. Section 101, or any successor statute (unless, in the case
of a petition filed against Tenant, such petition is dismissed within sixty (60)
days after its original filing); the institution of proceedings under bankruptcy
or similar laws in which Tenant is the debtor or bankrupt; the appointing 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 (unless possession
is restored to Tenant within sixty (60) days after such taking); or the
attachment, execution of judicial seizure of substantially all of Tenant's
assets located at the Premises or Tenant's interest in this Lease (unless such
attachment,

execution or judicial seizure is discharged within sixty (60) days after such
attachment, execution or judicial seizure).

12.2 LANDLORD'S REMEDIES: Landlord shall have the following remedies if
Tenant commits a default or breach under this Lease; these remedies are not
exclusive, but are cumulative in addition to any remedies provided elsewhere in
this Lease or now or later allowed by law.

(a) Continuation of Lease: No act by Landlord (including without
limitation the acts set forth in this Section 12.2(a)) shall terminate Tenant's
right to possession unless Landlord notifies Tenant in writing that Landlord
elects to terminate Tenant's right to possession. As long as Landlord does not
terminate Tenant's right to possession, Landlord may (i) continue this Lease in
effect, (ii) continue to collect rent when due and enforce all the other
provisions of this Lease, (iii) enter the Premises and relet them, or any part
of them, to third parties for Tenant's account, for a period shorter or longer
than the remaining term of this Lease, and (iv) have a receiver appointed to
collect rent and conduct Tenant's business. Tenant shall immediately pay to
Landlord all costs Landlord incurs in such reletting, including, without
limitation, brokers' commissions, attorneys' fees, advertising costs and
expenses of remodeling the Premises of such reletting.

(b) Rent from Reletting: If Landlord elects to relet all or any portion
of the Premises as permitted by Section 12.2(a), rent that Landlord receives
from such reletting shall be applied to the payment of, in the following order
and priority, (i) any indebtedness due from Tenant to Landlord (other than Base
Rent), (ii) all costs incurred by Landlord in such reletting, including without
limitation any brokers', finders', or leasing agents' commissions, charges or
fees, and (iii) Base Rent due and unpaid under this Lease. After applying such
payments as referred to above, any sum remaining from the rent Landlord receives
from such reletting shall be held by Landlord and applied in payment of future
Base Rent as it becomes due under this Lease. In no event shall Tenant be
entitled to any excess rent received by Landlord.

(c) Termination of Tenant's Right to Possession: Landlord may terminate
Tenant's right to possession of the Premises at any time, by notifying Tenant in
writing that Landlord elects to terminate Tenant's right to possession. On
termination of this Lease, Landlord has the right to recover from Tenant (i) the
worth at the time of the award of the unpaid Base Rent which had been earned at
the time of such termination, (ii) the worth at the time of the award of the
amount by which the unpaid Base Rent which would have been earned after such
termination until the time of award exceeds the amount of such loss of Base Rent
that Tenant proves could have been reasonably avoided, (iii) the worth at the
time of the award of the amount by which the unpaid Base Rent for the balance of
the Term after the time of award (had there been no such termination) exceeds
the amount of such loss of Base Rent that Tenant proves could be reasonably
avoided, and (iv) any other amount necessary to compensate Landlord for all
detriment proximately caused by Tenant's failure to perform Tenant's obligations
under this Lease or in the ordinary course of things would be likely to result
therefrom. The "worth at the time of the award" of the amounts referred to in
Sections 12.2(c)(i) and 12.2(c)(ii) is to be computed by allowing interest at a
rate equal to ten percent (10%) per annum, but in no event greater than the
maximum rate permitted by applicable law. The "worth at the time of the award"
of the amount referred to in Section 12.2(c)(iii) is to 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%).

(d) Landlord's Right to Cure Default: Landlord, at any time after
Tenant commits a default or breach under this Lease, may cure such default or
breach at Tenant's sole cost. If Landlord at any time, by reason of Tenant's
default or breach, pays any sum or does any act that requires the payment of any
sum, such sum shall be due immediately from Tenant to Landlord at the time such
sum is paid, and shall be deemed additional rent under this Lease.

12.3 INTEREST AND LATE CHARGES: Rent not paid within five (5) days after
its due date shall bear interest from the date due at a rate equal to ten
percent (10%) per annum, but in no event greater than the maximum rate permitted
by applicable law. Late payment by Tenant to Landlord of Rent will cause
Landlord to incur cost not contemplated by this Lease, the exact amount of which
would be impracticable or extremely difficult to fix. Such costs include,
without limitation, processing, collection and accounting charges, and late
charges that may be imposed on Landlord by the terms of any Mortgage covering
the Premises. Therefore, if any Rent is not received by Landlord within three
(3) business days after notice

to the Chief Financial Officer of Tenant of such overdue payment from Landlord
to Tenant, Tenant shall pay to Landlord an additional sum of five percent (5%)
of such overdue amount as a late charge ("Late Charge"). Landlord and Tenant
agree that the Late Charge represents a fair and reasonable estimate of the
costs that Landlord will incur by reason of any late payment by Tenant, and
therefore this Section 12.3 is reasonable under the circumstances existing at
the time this Lease is executed. Acceptance of the Late Charge by Landlord shall
not 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
available to Landlord under this Lease.

12.4 QUARTERLY PAYMENTS: In the event that a Late Charge is payable under
this Lease, whether or not collected, for three (3) consecutive installments of
Rent or in the event Rent is paid more than thirty (30) days late twice due
under this Lease during any twelve (12) month period, then Base Rent, and
Monthly Payment, shall, at Landlord's election by written notice to Tenant,
become due and payable quarterly in advance, rather than monthly, for a period
of six (6) months. If a Late Charge is payable under the Lease, whether or not
collected, for two (2) installments of Rent during the twelve (12) calendar
months following such six (6) month period, then Base Rent and Monthly Payment
shall automatically become due and payable quarterly in advance for a period of
one (1) year. If any payment is not timely paid during such one year period,
then Base Rent and Monthly Payment shall automatically become due and payable
quarterly in advance for the remaining Term of the Lease. All monies paid to
Landlord under this Section 12.4 may be commingled with other monies of Landlord
and shall not bear interest.

12.5 WAIVER: No delay or omission in the exercise of any right or remedy of
Landlord in the event of any default by Tenant shall impair such right or remedy
or be construed as a waiver. The receipt and acceptance by Landlord of
delinquent Rent shall not constitute a waiver of any default other than the
particular rent payment accepted. Landlord's receipt and acceptance from Tenant,
on any date ("Receipt Date"), of an amount less than rent due on such Receipt
Date, or to become due (pursuant to Section 4 or Section 6) at a later date but
applicable to a period prior to such Receipt Date, shall not release Tenant of
its obligation (a) to pay the full amount of such rent due on such Receipt Date
or (b) to pay when due the full amount of such rent to become due at a later
date but applicable to a period prior to such Receipt Date. No act or conduct of
Landlord, including without limitation, the acceptance of the keys to the
Premises, shall constitute an acceptance by Landlord of the surrender of the
Premises by Tenant before the Expiration Date or Option Expiration Date. Only a
written notice from Landlord to Tenant stating Landlord's election to terminate
Tenant's right to possession of the Premises shall constitute acceptance of the
surrender of the Premises and accomplish a termination of this Lease. Landlord's
consent to or approval of any act by Tenant requiring Landlord's consent or
approval shall not be deemed to waive or render unnecessary Landlord's consent
to or approval of any other or subsequent act by Tenant. Any waiver by Landlord
of any default by Tenant must be in writing and shall not be a waiver of any
other default concerning the same or any other provision of this Lease.

12.6 NOTICE OF DEFAULT: Landlord shall not be deemed to be in default in
the performance of any obligation required to be performed by Landlord unless
and until it has failed to perform such obligation within thirty (30) days after
Landlord's receipt of written notice from Tenant specifying Landlord's failure
to perform such obligation. However, if the nature of Landlord's obligation is
such that more than thirty (30) days are required for its performance, then
Landlord shall not be deemed to be in default if it shall commence such
performance within such thirty (30) day period and thereafter prosecutes the
same to completion.

SECTION 13
SUBORDINATION, ATTORNMENT, ESTOPPEL, AND NON-DISTURBANCE

13.1 SUBORDINATION: This Lease and Tenant's rights under this Lease are
subject and subordinate to any mortgage, loan secured by a deed of trust, or
other written security instrument or agreement affecting the Project that
constitutes security for the payment of a debt or performance of an obligation
(each, a "Mortgage"), and to all renewals, modifications, consolidations,
replacements or extensions thereof, now or hereafter affecting the Premises. The
provisions of this Section 13.1 shall be self-operative, and no further
instrument of subordination shall be required. Within fifteen (15) days after
written notice from Landlord, Tenant shall execute and deliver any instruments
that Landlord, the holder of any Mortgage, or the lessor of any ground or
underlying lease may reasonably request to evidence

such subordination. If Tenant fails to execute and deliver any such
instrument(s) within fifteen (15) days after such notice, Tenant agrees that
Landlord may then send a second notice and irrevocably constitutes and appoints
Landlord as Tenant's special attorney-in-fact to execute and deliver such
instruments on behalf of Tenant ten (10) days after Landlord's second written
notice to Tenant to execute and deliver requested instrument(s) and Tenant fails
to do so. If Landlord executes documents on behalf of Tenant pursuant to the
special power-of-attorney, it shall be deemed that Tenant has not waived any
rights against Landlord solely due to the use of the special power-of-attorney
by Landlord.

13.2 ATTORNMENT: If the holder of any Mortgage shall hereafter succeed to
the Landlord under this Lease, Tenant shall attorn to and recognize such
successor as the Landlord under this Lease, and shall promptly execute and
deliver any instruments that may be necessary to evidence such attornment. If
Tenant fails to execute and deliver any such instrument(s) within fifteen (15)
days after written notice from Landlord, Tenant agrees that Landlord may then
send a second notice and irrevocably appoints Landlord as Tenant's special
attorney-in-fact to execute and deliver such instruments on behalf of Tenant ten
(10) days after Landlord's second written notice to Tenant to execute and
deliver requested instrument(s) and Tenant fails to do so. If Landlord executes
documents on behalf of Tenant pursuant to the special power-of-attorney, it
shall be deemed that Tenant has not waived any rights against Landlord or such
successor solely due to the use of the special power-of-attorney by Landlord.
Upon such attornment, this Lease shall continue in effect as a direct lease
between such successor landlord and Tenant upon and subject to all of the
provisions of this Lease.

13.3 ESTOPPEL CERTIFICATES: Within fifteen (15) days after written notice
from Landlord, Tenant shall execute and deliver to Landlord, in recordable form,
a certificate in the form of Exhibit "I" stating (i) that this Lease is
unmodified and in effect, or in effect as amended, and stating all amendments;
(ii) the amount of Base Rent; (iii) the date to which Base Rent has been paid in
advance; (iv) the amount of any security deposit, prepaid rent or other payment
constituting rent which has been paid; (v) whether or not Tenant or Landlord is
in default under this Lease; and (vi) such other matters as Landlord shall
reasonably request. Tenant's failure to deliver such estoppel certificate within
such fifteen (15) day period shall be conclusive upon Tenant for the benefit of
Landlord, and any successor in interest to Landlord, that this Lease is in
effect and has not been amended except as may be represented by Landlord, no
rent has been paid more than thirty (30) days in advance and neither Landlord
nor Tenant is in default under this Lease. If Tenant fails to deliver such
estoppel certificate within such fifteen (15) day period, then Tenant agrees
that Landlord may then send a second notice and irrevocably constitutes and
appoints Landlord as its special attorney-in-fact to execute and deliver such
certificate to any third party ten (10) days after Landlord's second written
notice to Tenant to execute and deliver an estoppel certificate and Tenant fails
to do so. Landlord shall execute and deliver a similar estoppel certificate
within fifteen (15) days after written request by Tenant. If Landlord executes
documents on behalf of Tenant pursuant to the special power-of-attorney, it
shall be deemed that Tenant has not waived any rights against Landlord by reason
of the contents of the estoppel certificate signed pursuant to the special
power-of-attorney by Landlord.

13.4 NON-DISTURBANCE AGREEMENT: Landlord shall, within ten (10) days after
the date of this Lease, obtain from ▇▇▇▇ ▇▇▇▇▇▇ Insurance Company and each other
holder of a Mortgage in existence at the time of execution of this Lease a duly
executed non-disturbance agreement in the form of Exhibit "H". With respect to
any Mortgages which are not in existence at the time of execution of this Lease,
Landlord shall obtain a non-disturbance agreement in the form of Exhibit "H"
duly executed in recordable form by any holders of any future Mortgage as a
condition to this Lease being subordinate and junior to such future Mortgage and
as a condition to the recordation of any such future Mortgage. Notwithstanding
any other provision in this Section 13, no special power-of-attorney in favor of
Landlord or agreement to attorn by Tenant shall have force or effect unless a
non-disturbance agreement substantially in the form of Exhibit "H" was
previously or concurrently delivered to Tenant.

SECTION 14
SURRENDER OF PREMISES, HOLDING OVER

14.1 SURRENDER OF PREMISES: By the Expiration Date, Option Expiration Date
or earlier termination of this Lease, (i) Tenant shall surrender to Landlord the
Premises, including without limitation all Alterations, in Good Condition
(except for destruction to the Premises covered by Section 9) except for
Alterations that Tenant is obligated to remove under Section 7.9, (ii) Tenant
shall remove all its Personal Property and perform all repairs and restoration
required by the removal of any Alterations or Personal

Property at its sole cost, and (iii) Tenant shall surrender to Landlord all keys
to the Premises (including without limitation any keys to exterior or interior
office doors) and all permits, validations, keycards, passes, and similar items
with respect to the Premises and parking lot. Landlord may elect to retain or
dispose of in any manner any Alterations or Personal Property that Tenant does
not remove from the Premises on the Expiration Date, Option Expiration Date or
earlier termination of this Lease as required by this Lease by giving written
notice to Tenant. Title to any such Alterations or Personal Property that
Landlord elects to retain or dispose of shall vest in Landlord. Tenant waives
all claims against Landlord for any damage to Tenant resulting from Landlord's
retention or disposition of any such Alterations or Personal Property after the
Expiration Date or earlier termination of this Lease. Tenant shall be liable to
Landlord for Landlord's costs for storing, removing or disposing of any such
Alterations or Personal Property. If Tenant fails to surrender the Premises to
Landlord on the Expiration Date or earlier termination of this Lease, Tenant
shall indemnify and defend Landlord against all liability, loss and claims
resulting from such failure including without limitation any claim for damages
made by any other tenant or subtenant.

14.2 HOLDING OVER: If Tenant, with Landlord's written consent, remains in
possession of the Premises after the Expiration Date, Option Expiration Date or
earlier termination of this Lease, such possession by Tenant shall be deemed to
be a month-to-month tenancy terminable on thirty (30) days written notice given
at any time by Landlord or Tenant. During any such month-to-month tenancy,
Tenant shall pay as Base Rent one hundred twenty-five percent (125%) of the Base
Rent in effect immediately prior to the Expiration Date or earlier termination
of this Lease, as the case may be. All provisions of this Lease except for those
pertaining to the Term shall apply to such month-to-month tenancy.

of the Work Letter (Exhibit "C").

(b) "Unavoidable Delays" shall have the meaning set forth in Paragraph
11 of the Work Letter.

15.2 Delay In Occupancy:

(a) If, as of November 29, 1994, Tenant's Occupancy or Substantial
Completion has not occurred and there are more than one hundred and eighty-one
(181) days of combined Landlord Delay and Unavoidable Delay, this Lease shall,
at Tenant's option, terminate. If, as of November 29, 1994, Tenant's Occupancy
or Substantial Completion has not occurred and there are more than one hundred
and eighty-one (181) days of Unavoidable Delay, this Lease shall, at Landlord's
option, terminate. If, as of November 29, 1994, Tenant's Occupancy or
Substantial Completion has not occurred and there are more than one hundred and
eighty-one (181) days of combined Landlord Delay and Unavoidable Delay and
Tenant is not using reasonable efforts to obtain Substantial Completion, this
Lease shall, at Landlord's option, terminate.

(b) If the Commencement Date is later than June 1, 1994 and there are
more than fourteen (14) days of Landlord Delay, Landlord shall pay to Tenant
that portion of rent at Tenant's address or other location that exceeds Base
Rent ("Reimbursed Rent") and moving and storage costs attributed solely to the
delay in the Commencement Date ("Reimbursed Moving and Storage Cost") from June
1, 1994 until the Commencement Date or July 5, 1994 whichever is earlier. If the
Commencement Date is later than July 5, 1994 and there are more than thirty-four
(34) days of Landlord Delay, Landlord shall pay to Tenant Reimbursed Rent and
Reimbursed Moving and Storage Cost from June 1, 1994 until the Commencement Date

that Landlord shall not be obligated to pay Reimbursement Rent and Reimbursed
Moving and Storage Costs for any period beyond June 1, 1994 through November 29,
1994.

(c) Landlord shall have no liability for Landlord Delay or Unavoidable
Delay except as specifically set forth in Sections 1.4 and 15.2 of this Lease.

(d) Tenant's occupancy of the Premises at any time shall conclusively
be deemed a waiver by Tenant of this Section 15 except for any sums Landlord may
owe to Tenant pursuant to this Section 15.

SECTION 16
GENERAL PROVISIONS

16.1 BROKERS: Tenant represents that, except as set forth in this Section
16.1, no real estate broker, agent, finder, or other person is responsible for
bringing about or negotiating this Lease and that Tenant has not dealt with any
real estate broker, agent, finder, or other person with respect to this Lease in
any manner. Tenant shall indemnify and defend Landlord against all liability,
costs, expenses and charges (including without limitation attorneys' fees and
disbursements) arising from any claims that may be made against Landlord by any
real estate broker, agent, finder, or other person alleging to have acted on
behalf of or to have dealt with Tenant, prior to the Commencement Date and
during the Term. Landlord retained CB Commercial Real Estate Group Inc. ("CB
Commercial") as a leasing broker and shall be responsible for all commissions
paid to CB Commercial regarding this Lease. Tenant retained ▇▇▇▇▇▇▇ Realty
Corporation ("▇▇▇▇▇▇▇"), as exclusive agent for Tenant. Landlord shall pay to
▇▇▇▇▇▇▇ a real estate brokerage commission ("Commission") of five percent (5%)

Re: Pacific Corporate Park
5930 and ▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇
HVAC System

Dear ▇▇▇▇▇:

The subject buildings are serviced by a "Tri-Water" water source heat pump
system. The central plant, which houses a separate cooling tower, boiler and
recirculating pump for each building, is located in the parking area north of
building A. The condenser water is piped underground to each building and
connected to the fire sprinkler system which is routed throughout both
buildings. The individual water source heat pumps are then connected to the
fire sprinkler piping as a part of the tenant improvement.

The cooling towers installed are rated @ 350 GMP which would provide the
equivalent of approximately ?? tons of air conditioning capability for each
building. There is a 4 wire energy management loop that is routed from the
central plant to each building for connection to future tenant Water Source
Heat Pump ("WSHP") units. This allows the tenant to communicate with the
central plant .a provide after hours cooling.

As part of the tenant improvement buildout, the following should be utilized
as guidelines for a minimum standard:

1. Suspend WSHP units above the ceiling utilizing 1 in. spring
isolation for vibration and sound attenuation.

2. Type L copper piping with hard solider should be utilized for the
condenser water piping to the individual WSHP units. Automatic flow controls
are required for each unit.

3. The return air must be ducted and both supply and return ducts must be
insulated.

4. Rigid duct to be utilized with flex duct on the last 7 ft. only.

5. Check valves must be installed on the condenser piping to the
ndividual WSHP units.

6. Duct shall be sized at .1 in. pressure drop per 100 ft. of duct.

7. Perimeter and interior zones shall not be combined.

B. WSHP units shall be equivalent to Carrier, Trane or AAF.

9. Outside air shall be provided @ 20 CFM/person.

Should you have any additional questions or comments, please do not hesitate to
call.

Sincerely,

sufficiency of which are hereby acknowledged, Assignor and Assignee agree as set
forth below.

1. Assignment. Assignor hereby assigns to Assignee all of its right,
title and interest under the Lease which assignment shall be effective as of the
Effective Date (as defined below). The effective date of the assignment of the
Lease (the "Effective Date") shall be the date that Assignor vacates the entire
Premises to move to its new facility. The parties currently estimate that the
Effective Date will occur on September 6, 1998. Assignor shall give written
notice to Assignee (the "Effective Date Notice") six (6) months prior to
Assignor's then estimated Effective Date (the "Estimated Effective Date"). In
addition, Assignor shall give Assignee regular updates as to the status of
Assignor's schedule to vacate the Premises and shall promptly notify Assignee of
any changes to the Estimated Effective Date, provided that the Estimated
Effective Date shall not be earlier than the date set forth in Assignor's
Effective Date Notice without Assignee's consent. In addition, Assignor shall
give Assignee at least thirty (30) days prior written notice of the actual
Effective Date to allow Assignee to schedule its move in to the Premises. If
Assignor does not deliver the Effective Date Notice by September 6, 1998, or if
the Effective Date does not occur by March 6, 1999, Assignee shall have the
right to terminate this Assignment by giving written notice of termination to
Assignor, and, upon such termination, neither party shall have any further
rights or obligations under this Assignment. On the Effective Date, Assignor

by Section 14.1 of the Lease as such provision applies to the expiration or
earlier termination of the Lease and with all Building systems in good

working order. Except as provided in the preceding sentence, the Premises shall
be delivered to Assignee in its "as-is" condition existing on the date of this
Assignment, subject to normal wear and tear between the date of this Assignment
and the Effective Date.

further agrees to faithfully perform and be bound by all of the terms,
covenants, conditions, provisions and agreements of the Lease from and after the
Effective Date.

3. Indemnity. Assignor agrees to indemnify, defend (with counsel
reasonably acceptable to Assignee) and hold Assignee and its officers,
directors, shareholders, agents, employees and affiliates harmless from and
against any and all claims, actions, liabilities, damages, costs and expenses
(including, without limitation, attorneys' fees and costs incurred in connection
therewith or to enforce this indemnity obligation) arising from or relating to
any obligations to be performed by Assignor under the Lease prior to the
Effective Date and/or any acts or omissions of Assignor in connection with the
Lease prior to the Effective Date. Assignee agrees to indemnify, defend (with
counsel reasonably acceptable to Assignor) and hold Assignor and its officers,
directors, shareholders, agents, employees and affiliates harmless from and
against any and all claims, actions, liabilities, damages, costs and expenses
(including, without limitation, attorneys' fees and costs incurred in connection
therewith or to enforce this indemnity obligation) arising from or relating to
any obligations to be performed by Assignee under the Lease on or after the
Effective Date and/or any acts or omissions of Assignee in connection with the
Lease on or after the Effective Date. Notwithstanding the foregoing, if
Assignee's move-in is phased pursuant to Section 6 below, Assignor's indemnity
obligation shall continue, and Assignee's indemnity obligation shall not
commence, with respect to each phase until Assignor delivers possession of such
phase to Assignee.

4. Security Deposit. Notwithstanding the assignment of the Lease as
provided herein, Assignor shall retain all rights to the security deposit
delivered to Landlord under the Lease in the amount of $48,984 (the "Security
Deposit"). The Security Deposit shall be paid by Landlord directly to Assignor
in accordance with the terms of the Lease. Assignee agrees to immediately
deliver the Security Deposit to Assignor if the Security Deposit is paid to
Assignee notwithstanding the preceding sentence. In addition, Assignee agrees to
immediately reimburse Assignor for any deductions from the Security Deposit made
by Landlord in accordance with the Lease as a result of Assignee's failure to
perform its obligations under the Lease from and after the Effective Date.
Assignee shall also be obligated to pay (or to cause Landlord to pay) to
Assignor an amount equal to the Security Deposit if Assignee and Landlord (a)
terminate the Lease and enter into a new lease of the Premises or (b) modify the
material terms of the Lease.

5. Covenants, Representations and Warranties of Assignor. Assignor
hereby represents and warrants to Assignee that (i) Assignor has not previously

that the Lease is in full force and effect and has not been modified or amended
except as provided in the First Amendment and the Second Amendment described

respects as of the date of this Assignment and as of the Effective Date. Between

deliver to Assignee copies of any and all notices relating to the Lease and/or
the Premises, to timely perform all of its obligations under the Lease, and not

faith, if Assignor elects to phase-out of the Building at different times.
Assignor shall give written notice of such election to Assignee stating the
dates on which Assignor intends to vacate each portion of the Building. The
parties acknowledge and agree that each phase of the Building to be vacated by
Assignor must be sufficiently demised and otherwise appropriate for Assignee's
phased move-in and use. In the event of a phased move-in, Assignee shall only be
responsible for a proportionate share of the obligation to pay rent and other
amounts due under the Lease and the performance of other obligations under the
Lease based on a fraction, the numerator of which is the rentable area of the
portion of the Premises so occupied by Assignee, and the denominator of which is
the total rentable area of the Premises. In such event, Assignor shall remain
liable for its proportionate share of all payment and performance obligations
under the Lease. In no event shall the phase-out period be longer than six (6)
months after the date possession of the first phase of the Building is delivered
to Assignee.

7. Termination of Existing Sublease. Assignor, as sublessee, and
Assignee, as sublessor, have entered into that certain Sublease dated September
24, 1996 (the "Sublease") relating to space within the building located at ▇▇▇▇

Sublease shall terminate on the date Assignor fully vacates such space in
accordance with the Sublease and the parties shall be released of all
obligations under the Sublease from and after such date. Assignor shall give
Assignee at least six (6) months prior written notice of the date upon which it
will vacate such space.

8. Commission. Except for The ▇▇▇▇▇▇ ▇▇▇▇▇▇ Group, Inc. ("Broker"),
Assignor and Assignee each represent and warrant to the other that it has not
dealt with any party, whether or not licensed, that may be entitled to a
commission, finder's fee or similar compensation in connection with this
Assignment. Assignor and Assignee each agree to indemnify, defend (with counsel
reasonably acceptable to the other) and hold harmless the other party from and
against all claims, damages, liabilities, costs and expenses (including
attorneys' fees and costs incurred in connection therewith or to enforce this
indemnity agreement) arising from or relating to the indemnifying party's breach
of the foregoing representation and warranty.

3
87

9. Improvements. Assignee may desire to make improvements to the
Premises after the Effective Date. Assignor agrees to cooperate with Assignee to
apply for and seek Landlord's consent to such improvements in accordance with
the provisions of the Lease.

either party against the other relating to or arising from this Assignment or to
enforce or interpret any provision hereof, the prevailing party shall be
entitled to recover from the other party all costs and fees incurred in
