                                  SUBLEASE TERM

2.1 MASTER LEASE. Landlord is the ground lessee of the real property improved
with and identified as the Project under that certain Lease dated August 25,
1987, by and between the San Diego Unified School District ("District") as
lessor and Landlord as lessee (the "Master Lease"). The Master Lease provides
that Landlord may construct improvements and sublease portions thereof to
tenants. Accordingly, and subject to the Master Lease, Landlord is entering into
this sublease with Tenant.

2.2 SUBLEASE OF PREMISES FOR SUBLEASE TERM. Landlord subleases the Premises to
Tenant and Tenant subleases the Premises from Landlord for the Sublease Term.
The Sublease Term is for the period stated in Section 1.5 above and shall begin
and end on the dates specified in Section 1.5 above, unless the beginning or end
of the Sublease Term is changed under any provision of this Sublease. The
"Commencement Date" shall be the date specified in Section 1.5 above for the
beginning of the Sublease Term, unless advanced or delayed under any provision
of this Sublease.

2.3 DELAY IN COMMENCEMENT. Landlord shall not be liable to Tenant if Landlord
does not deliver possession of the Premises to Tenant on the first date
specified in Section 1.5 above. Landlord's non-delivery of the Premises to
Tenant on that date shall not affect this Sublease or the obligations of Tenant
under this Sublease. However, the Commencement Date shall be delayed until
possession of the Premises is delivered to Tenant. The Sublease Term shall be
extended for a period equal to the delay in delivery of possession of the
Premises to Tenant, plus the number of days necessary to end the Sublease Term
on the last day of a month. If Landlord does not deliver possession of the
Premises to Tenant within ninety (90) days after

                                      -2-
<PAGE>

the first date specified in Section 1.5 above, Tenant may elect to cancel this
Sublease by giving written notice to Landlord within ten (10) days after the
90-day period ends. If Tenant gives such notice, the Sublease shall be cancelled
and neither Landlord nor Tenant shall have any further obligations to the other.
If Tenant does not give such notice, Tenant's right to cancel the Sublease shall
expire and the Sublease Term shall commence upon the delivery of possession of
the Premises to Tenant. If delivery of possession of the Premises to Tenant is
delayed, Landlord and Tenant shall, upon such delivery, execute an amendment to
this Sublease setting forth the Commencement Date and expiration date of the
Sublease. For purposes of this Section 2.3, Landlord's delivery of possession of
the Premises shall mean the earlier of (i) the date Tenant occupies all or any
portion of the Premises, or (ii) the date upon which the Premises are
substantially complete in accordance with Exhibit A.

2.4 EARLY OCCUPANCY. If Tenant occupies the Premises prior to the Commencement
Date, Tenant's occupancy of the Premises shall be subject to all of the
provisions of this Sublease. Early occupancy of the Premises shall not advance
the expiration date of this Sublease. Tenant shall pay Base Rent and all other
charges specified in this Sublease for the early occupancy period.

2.5 HOLDING OVER. Tenant shall vacate the Premises upon the expiration or
earlier termination of this Sublease. Tenant shall reimburse Landlord for and
indemnify Landlord against all damages incurred by Landlord from any delay by
Tenant in vacating the Premises. If Tenant remains in possession of all or any
part of the Premises after the expiration of the term hereof, with or without
the express or implied consent of Landlord, such tenancy shall be from
month-to-month only and not a renewal hereof or an extension for any further
term, and in such case, Base Rent then in effect shall be increased by
twenty-five percent (25%) and other monetary sums due hereunder shall be payable
in the amount and at the time specified in this Sublease; and such
month-to-month tenancy shall be subject to every other term, covenant and
agreement contained herein, except that the month-to-month tenancy will be
terminable on thirty (30) days notice given at any time by either party.

2.6 SURRENDER OF PREMISES. Upon the termination of the Sublease, Tenant shall
surrender the Premises to Landlord in the condition specified in and according
to Section 6.7.

                                  Article III
                                   BASE RENT

3.1 TIME AND MANNER OF PAYMENT. Upon execution of this Sublease, Tenant shall
pay Landlord the Base Rent in the amount stated in Subsection 1.9.1 above for
the first month of the Sublease Term. On the first day of the second month of
the Sublease Term and each month thereafter, Tenant shall pay Landlord the Base
Rent in United States currency, in advance, without offset, deduction or prior
demand. The Base Rent shall be payable at Landlord's address or at such other
place as Landlord may designate in writing.

3.2 INCREASE. The Base Rent shall be increased at the times specified in
Subsection 1.9.1 above. Tenant shall be obligated to pay the new Base Rent from
its effective date until the next periodic increase without any prior notice
from Landlord.

3.3   SECURITY DEPOSIT INCREASES.

3.3.1 DEPOSIT. Upon the execution of this Sublease, Tenant shall deposit with
      Landlord a cash Security Deposit in the amount set forth in Section 1.8
      above. Landlord may apply all or part of the Security Deposit to any
      unpaid rent or other charges due from Tenant or to cure any other defaults
      of Tenant. If Landlord uses any part of the Security Deposit, Tenant shall
      restore the Security Deposit to its full amount within ten (10) days after
      Landlord's written request. Tenant's failure to do so shall be a material
      default under this Sublease. No interest shall be paid on the Security
      Deposit. Landlord shall not be required to keep the Security Deposit
      separate from its other accounts and no trust relationship is created with
      respect to the Security Deposit.

3.4 TERMINATION; ADVANCE PAYMENTS. Upon termination of this Sublease under
Article Seven (Damage or Destruction), Article Eight (Condemnation), or any
other termination not resulting from Tenant's default, and after Tenant has
vacated the Premises in the manner required by this Sublease, an equitable
adjustment shall be made concerning advance rent, any other advance payments
made by Tenant to Landlord, and accrued real property taxes, and Landlord shall
refund the unused portion of the Security Deposit to Tenant or Tenant's
successor.

Article IV
                         OTHER CHARGES PAYABLE BY TENANT

4.1 ADDITIONAL RENT. All charges payable by Tenant other than Base Rent are
called "Additional Rent." Unless this Sublease provides otherwise, all
Additional Rent shall be paid with the next monthly installment of Base Rent and
shall be in United States currency. The term "rent" shall mean Base Rent and
Additional Rent.

4.2 REAL PROPERTY TAXES.

      4.2.1 PAYMENT OF TAXES. Tenant shall pay its proportionate share of all
real property taxes and general and special assessments, levied and assessed
against the Project of which the Premises are a part. Tenant's proportionate
share of real property taxes shall be the ratio that the total number of square
feet in the Premises bears to the total number of sub-leasable square feet in
the Project. Each year Landlord shall notify Tenant of Landlord's calculation of
Tenant's proportionate share of the real property taxes and together with such
notice shall furnish Tenant with a copy of the tax bill. If any supplemental tax
bills are delivered with respect to the Project, Landlord may notify Tenant of
Landlord's new calculation of Tenant's proportionate share of real property
taxes as soon as such supplemental tax bill is received. Subject to Section 4.8
below, Tenant shall reimburse Landlord for Tenant's proportionate share of the
Real Property Taxes semiannually no later than fifteen (15) days before the
taxing authority's delinquency date.

      4.2.2 DEFINITION OF "REAL PROPERTY TAX." "Real Property Tax" means: (i)
any fee, license fee, license tax, commercial rental tax, levy, charge,
assessment, penalty or tax (other than inheritance or estate taxes) imposed by
any authority having the direct or indirect power to tax, including any City,
County, State or Federal government, or any school, agriculture, lighting,
drainage or other improvement district thereof, as against any legal or

                                      -4-
<PAGE>

equitable interest of Landlord in the Premises; (ii) any tax on the Landlord's
right to receive, or the receipt of, rent or income from the Premises or against
Landlord's business of leasing the Premises; (iii) any tax or charge for fire
protection, streets, sidewalks, road maintenance, refuse or other services
provided to the Premises by any governmental agency; (iv) any tax imposed upon
this transaction or based upon a reassessment of the Premises due to a change in
ownership or transfer of all or part of Landlord's interest in the Premises; and
(v) any charge or fee replacing any tax previously included within the
definition of Real Property Tax. "Real Property Tax" does not, however, include
Landlord's Federal or State income, franchise, inheritance or estate taxes.

      4.2.3 JOINT ASSESSMENT. If the Premises is not separately assessed,
Tenant's share of the Real Property Tax payable by Tenant under Subsection 4.2.1
shall be determined from reasonably available information. Landlord shall make a
reasonable determination of Tenant's proportionate share of such real property
tax and Tenant shall pay such share to Landlord within fifteen (15) days after
receipt of Landlord's written statement.

      4.2.4 PERSONAL PROPERTY TAXES.

            (a) Tenant shall pay prior to delinquency all taxes charged against
trade fixtures, furnishings, equipment or any other personal property belonging
to Tenant. Tenant shall attempt to have such personal property taxed separately
from the Premises.

            (b) If any such taxes on Tenant's personal property are levied
against Landlord or Landlord's Premises, or if the assessed value of the
Premises is increased by the inclusion therein of a value placed upon such
personal property or trade fixtures of Tenant, then Landlord, after written
notice to Tenant, shall have the right to pay the taxes based upon such
increased assessments, regardless of the validity thereof, but only under proper
protest if requested by Tenant in writing. If Landlord shall do so, then Tenant
shall, upon demand, repay to Landlord the taxes levied against Landlord, or the
proportion of such taxes resulting from such increase in the assessment. In any
such event, however, Tenant, at Tenant's sole cost and expense, shall have the
right, in the name of Landlord and with Landlord's full cooperation, to bring
suit in any court of competent jurisdiction to recover the amount of any such
taxes so paid under protest; any amount so recovered to belong to Tenant.

            (c) If any of Tenant's personal property is taxed with the Premises,
Tenant shall pay Landlord the taxes for the personal property within fifteen
(15) days after Tenant receives a written statement from Landlord for such
personal property taxes.

      4.2.5 TENANT'S RIGHT TO CONTEST TAXES. Tenant may attempt to have the
assessed valuation of the Premises reduced or may initiate proceedings to
contest the Real Property Tax. If required by law, Landlord shall join in the
proceedings brought by Tenant. However, Tenant shall pay all costs of the
proceedings, including any costs or fees incurred by Landlord. Upon the final
determination of any proceeding or contest, Tenant shall immediately pay the
excess Real Property Tax due, together with all costs, charges, interest and
penalties incidental to the proceedings. If Tenant does not pay the excess Real
Property Tax when due when due and contests such taxes, Tenant shall not be in
default under this Sublease for nonpayment of such taxes if Tenant deposits
funds with Landlord or opens an interest bearing

                                      -5-
<PAGE>

account reasonably acceptable to Landlord in the joint names of Landlord and
Tenant. The amount of such deposit shall be sufficient to pay the excess Real
Property Tax plus a reasonable estimate of the interest, costs, charges and
penalties which may accrue if Tenant's action is unsuccessful, less any
applicable tax impounds previously paid by Tenant to Landlord. The deposit shall
be applied to the excess Real Property Tax due, as determined at such
proceedings. The excess Real Property Tax shall be paid under protest from such
deposit if such payment under protest is necessary to prevent the Premises from
being sold under a "tax sale" or similar enforcement proceeding.

4.3 UTILITIES. Tenant shall arrange for and pay, directly to the appropriate
supplier, the cost of all natural gas, heat, light, power, sewer, telephone,
water and other utilities and services supplied to the Premises. Landlord will
cooperate in attempting to have each of the utilities supplied to the Premises
separately metered. However, if any such utilities or services are jointly
metered with other premises within the Project, Landlord shall make a reasonable
determination of Tenant's proportionate share of the cost of such utilities and
services, based on information reasonably available to Landlord, and Tenant
shall pay such share to Landlord within fifteen (15) days after receipt of
Landlord's written statement of such cost.

4.4 INSURANCE PREMIUMS.

      4.4.1 LIABILITY INSURANCE. During the Sublease Term, Landlord shall
maintain a policy of comprehensive public liability insurance at Tenant's
expense, insuring Landlord against liability arising out of the ownership, use,
occupancy or maintenance of the Premises. The initial amount of such insurance
shall be at least $5,000,000.00, and shall be subject to periodic increase based
upon inflation, increased liability awards, recommendations of professional
insurance advisers, and other relevant factors. However, the amount of such
insurance shall not limit Tenant's liability nor relieve Tenant of any
obligation hereunder. The policy shall contain cross-liability endorsements, if
applicable, and shall insure Tenant's performance of the indemnity provisions of
Section 5.4. Tenant shall, at Tenant's expense, maintain such other liability
insurance as Tenant deems necessary to protect Tenant.

      4.4.2 HAZARD AND RENTAL INCOME INSURANCE. During the Sublease Term,
Landlord shall, at Tenant's expense, maintain policies of insurance covering
loss of or damage to the Premises to the extent of at least one hundred percent
(100%) of its replacement value. Such policies shall provide protection against
all perils included within the classification of fire, extended coverage,
vandalism, malicious mischief, and any other perils which Landlord deems
necessary. Landlord may obtain insurance coverage for Tenant's fixtures,
equipment or building improvements installed by Tenant in or on the Premises.
Tenant shall, at Tenant's expense, maintain such primary or additional insurance
on its fixtures, equipment and building improvements as Tenant deems necessary
to protect its interest. During the Sublease Term, Landlord may also maintain a
rental income insurance policy at Tenant's expense, with loss payable to
Landlord in an amount equal to one year's Base Rent (as adjusted periodically),
estimated Real Property Taxes and insurance premiums. Tenant shall not do or
permit to be done anything which invalidates any such insurance policies.

      4.4.3 PAYMENT OF PREMIUMS; INSURANCE POLICIES. Tenant shall pay its pro
rata share of the premiums for maintaining the insurance required by Subsections
4.4.1 and

                                      -6-
<PAGE>

4.4.2. Tenant's pro rata share of all such premiums shall be based on
the same proportion as used for payment of taxes pursuant to Subsection 4.2.1
hereof. All such amounts will be due and payable upon ten (10) days written
notice.

      4.4.4 INCREASE IN FIRE INSURANCE PREMIUM. Tenant agrees that it will not
keep, use, manufacture, assemble, sell or offer for sale in or upon the Premises
any article which may be prohibited by the standard form of fire insurance
policy. Tenant agrees to pay any increase in premiums for fire and extended
coverage insurance that may be charged during the term of this Sublease on the
amount of such insurance which may be carried by Landlord on said Premises or
the building of which it is a part, resulting from the acts or omissions of the
Tenant, its agents, servants or employees, or the use or occupancy of the
Premises by the Tenant or from the type of materials or products stored,
manufactured, assembled or sold by Tenant in the Premises, whether or not
Landlord has consented to the same. In determining whether increased premiums
are the result of Tenant's use of the Premises, a schedule, issued by the
organization making the insurance rate on the Premises, showing the various
components of such rate, shall be conclusive evidence of the several items and
charges which make up the fire insurance rate on the Premises.

      4.4.5 WAIVER OF SUBROGATION. Landlord and Tenant each hereby waive any and
all rights of recovery against the other or against the officers, employees,
agents and representatives of the other, on account of loss or damage occasioned
to such waiving party or its property or the property of others under its
control, to the extent that such loss or damage is insured against under any
fire and extended coverage insurance policy which either may have in force at
the time of such loss or damage. Tenant shall, upon the policies of insurance
required under this Sublease, give notice to the insurance carrier or carriers
that the foregoing mutual waiver of subrogation is contained in this Sublease.

4.5 COMMON AREAS.

      4.5.1 DEFINITION; LOCATION. As used in this Sublease, "Common Areas" shall
mean all areas within the Project which are available for the common use of
tenants of the Project and which are not leased or held for the exclusive use of
tenants of the Project or which are not leased or held for the exclusive use of
Tenant or other tenants, including, but not limited to, parking areas,
driveways, sidewalks, loading areas, retaining walls, truck serviceways,
pedestrian malls, stairs, ramps, restrooms, access roads, corridors, landscaping
and planted areas. Landlord may from time to time change the size, location,
nature and use of the Common Areas, including converting Common Areas into
leasable areas, construction of additional parking facilities (including parking
structures) in the Common Areas, and increasing or decreasing Common Area land
and/or facilities. Tenant acknowledges that such activities may result in
occasional inconvenience to Tenant from time to time. Such activities and
changes shall be expressly permitted if they do not materially affect Tenant's
use of the Premises.

      4.5.2 USE OF COMMON AREAS. Subject to other provisions of this Sublease,
Tenant shall have the nonexclusive right (in common with other tenants and all
others to whom Landlord has granted or may grant such rights) to use the Common
Areas for the purposes intended, subject to such reasonable rules and
regulations as Landlord may establish from time to time. Tenant shall abide by
such rules and regulations and shall use its best effort to cause others

                                      -7-
<PAGE>

who use the Common Areas with Tenant's expressed or implied permission to abide
by Landlord's rules and regulations. At any time, Landlord may close any Common
Areas to perform any acts in and to the Common Areas as, in Landlord's judgment,
may be desirable to improve the Project. Tenant shall not, at any time,
intentionally interfere with the rights of Landlord, other tenants, or any other
person entitled to use the Common Areas.

      4.5.3 VEHICLE PARKING. Tenant shall be entitled to use 3.8 vehicle parking
spaces in the Project for each 1,000 (One Thousand) square feet within the
Premises without paying any additional rent. Tenant's parking shall not be
reserved and shall be limited to vehicles no larger than standard size
automobiles or pickup utility vehicles. Tenant shall not cause large trucks or
other large vehicles to be parked within the Project or on the adjacent public
streets. Vehicles shall be parked only in striped parking spaces and not in
driveways, loading areas or other locations not specifically designated for
parking. If Tenant parks more vehicles in the parking area than the number
identified herein, such conduct shall be a material breach of the Sublease.

      4.5.4 MAINTENANCE OF COMMON AREAS. Landlord shall maintain the Common
Areas in good order, condition and repair and shall operate the Project, in
Landlord's sole discretion, as a first class industrial/commercial real property
development. Tenant shall pay Tenant's pro rata share (as defined below) of all
costs incurred by Landlord for the operation and maintenance of the Common Area.
Common Area costs include, but are not limited to, costs and expenses for the
following: gardening and landscaping; pest extermination services; utilities,
water and sewage charges; maintenance of signs (other than Tenant's signs);
premiums for liability, property damage, fire and other types of casualty
insurance on the Common Areas and all Common Area improvements; all personal
properly taxes levied on or attributable to personal property used in connection
with the Common Areas; straight-line depreciation on personal property owned by
Landlord which is consumed in the operation or maintenance of the Common Areas;
rental or lease payments paid by Landlord for rented or leased personal property
used in the operation or maintenance of the Common Areas; the reasonable rental
value of any Common Area located within any building situated within the
Project; fees for management of the Project and Common Areas; fees for required
licenses and permits; repairing, resurfacing, repaving, maintaining , painting,
lighting, cleaning, refuse removal, security and similar items; reserves; and a
reasonable allowance to Landlord for Landlord's supervision of the Common Areas
(not to exceed five percent (5%) of the total of all other Common Area costs for
the calendar year). Landlord may cause any or all of such services to be
provided by third parties, or by entities associated with Landlord. Common Area
costs shall not include depreciation of real property which forms part of the
Common Areas. Landlord may, at Landlord's election, estimate in advance and
charge to Tenant monthly as Common Area costs, all real property taxes for which
Tenant is liable under the Sublease, all insurance premiums for which Tenant is
liable under the Sublease, and all maintenance and repair costs for which Tenant
is liable under the Sublease.

      4.5.5 TENANT'S SHARE AND PAYMENT. Tenant shall pay Tenant's annual pro
rata share of all estimated Common Area costs, in advance, in monthly
installments on the first day of each month during the Sublease Term (prorated
for any fractional month). Tenant's pro rata share shall be calculated by
dividing the square foot area of the Premises, as set forth in Section 1.4 of
the Sublease, by the aggregate square foot area of the leaseable area within the

                                      -8-
<PAGE>

Project, whether currently leased or not upon the date the computation is made.
Landlord may adjust such estimates at any time and from time to time based upon
Landlord's experience and reasonable anticipation of costs. Such adjustments
shall be effective as of the next rent payment date after notice to Tenant.
Within thirty (30) days after the end of each calendar year of the Sublease
Term, Landlord shall deliver to Tenant a statement prepared in accordance with
generally accepted accounting principles setting forth, in reasonable detail,
the actual Common Area costs paid or incurred by Landlord during the preceding
calendar year and Tenant's pro rata share. Upon receipt of such statement, there
shall be an adjustment between Landlord and Tenant with payment to or credit
given by Landlord (as the case may be) so that Landlord shall receive the entire
amount of Tenant's share of such costs and expenses for such period. Any changes
in the Common Area costs and/or the aggregate area leased or held for lease for
the exclusive use of all tenants of the Project during the Lease Term shall be
effective on the first day of the month after such change occurs.

      4.5.5.1 ALTERNATIVE PAYMENT. Notwithstanding the foregoing, Landlord has
the right to notify Tenant on a monthly or other basis of the actual amount
Landlord has expended for all Common Area costs incurred during the previous
month or period. Such notice shall also set forth Tenant's pro rata share of
such actual costs. Upon receipt of such statement, Tenant shall pay with the
next monthly installment of rent Tenant's pro rata share of the actual Common
Area costs incurred during the previous month or period.

      4.5.6 ADDITIONAL AREAS. In addition to the Common Areas and costs
associated therewith described in this Section 4.5, Landlord may, but is not
obligated to, provide certain additional spaces and areas within the Project
("Additional Areas") as (and included within the definition of) Common Areas.
The Additional Areas may include, but are not limited to, an office used by and
subject to the exclusive control of Landlord for leasing and/or managing the
Project, a conference room available on a reserved basis for use by tenants
within the Project during normal business hours, and a locker room facility for
use by tenants of the Project and their employees that are employed at the
Project. Common Area costs for which Tenant is liable for its pro rata share as
described in Section 4.5.4 shall include costs of operating and the reasonable
rental value of the space occupied by the Additional Areas.

4.6 LATE CHARGES. Tenant's failure to pay rent promptly may cause Landlord to
incur unanticipated costs. The exact amount of such costs is impractical or
extremely difficult to ascertain. Such costs may include, but are not limited
to, processing and accounting charges and late charges which may be imposed on
Landlord by any ground sublease, mortgage or trust deed encumbering the
Premises. Therefore, if Landlord does not receive any rent payment within five
(5) days after it becomes due, Tenant shall pay Landlord a late charge equal to
five percent (5%) of the overdue amount. The parties agree that such late charge
represents a fair and reasonable estimate of the costs Landlord will incur by
reason of such late payment.

      4.6.1 REPEATED LATE CHARGES. In the event that a late charge is payable
under this Sublease whether or not collected, for two installments of Base Rent
during any one calendar year of the Sublease Term, then the Base Rent shall
automatically become due and payable quarterly in advance, rather than monthly.
All monies paid to Landlord under this provision may be commingled with other
monies of Landlord and shall not bear interest.

                                      -9-
<PAGE>

4.7 INTEREST ON PAST DUE OBLIGATIONS. Any amount owed by Tenant to Landlord
which is not paid when due shall bear interest at the rate of ten percent (10%)
per annum or at the highest rate then permitted by law, whichever is less, from
the due date of such amount. However, interest shall not be payable on late
charges to be paid by Tenant under this Sublease. The payment of interest of
such amounts shall not excuse or cure any default by Tenant under this Sublease.
If the interest rate specified in this Sublease is higher than the rate
permitted by law, the interest rate is hereby decreased to the maximum legal
interest rate permitted by law.

4.8 IMPOUNDS FOR INSURANCE PREMIUMS AND REAL PROPERTY TAXES. If requested by any
ground lessor or lender to whom Landlord has granted a security interest in the
Premises or the Project if Landlord deems it necessary in Landlord's sole and
absolute discretion, or if Tenant is more than ten (10) days late in the payment
of rent more than once in any consecutive twelve (12) month period, Tenant shall
pay Landlord a sum equal to one-twelfth (1/12) of the annual Real Property Tax
and/or insurance premiums payable by Tenant under this Sublease, together with

actual cost of repair and any insurance proceeds received by Landlord. If
Landlord elects to terminate this Sublease, Tenant may elect to continue this
Sublease in full force and effect, in which case Tenant shall repair any damage
to the Premises and any building in which the Premises is located. Tenant shall
pay the cost of such repairs, except that, upon satisfactory completion of such
repairs, Landlord shall deliver to Tenant any insurance proceeds received by
Landlord for the damage repaired by Tenant. Tenant shall give Landlord written
notice of such election within ten (10) days after receiving Landlord's
termination notice. If the damage to the Premises occurs during the last six (6)
months of the Sublease Term, Landlord may elect to terminate this Sublease as of
the date the damage occurred, regardless of the sufficiency of any insurance
proceeds and Landlord may retain all such proceeds. In such event, Landlord
shall not be obligated to repair or restore the Premises and Tenant shall have
no right to continue this Sublease. Landlord shall notify Tenant of its election
within thirty (30) days after receipt of notice of the occurrence of the damage.

7.2 TOTAL OR SUBSTANTIAL DESTRUCTION. If the Premises is totally or
substantially destroyed by any cause whatsoever, or if the Premises is in a
building which is substantially destroyed (even though the Premises is not
totally or substantially destroyed), this Sublease shall, at the election of the
Landlord, terminate as of the date the destruction occurred regardless of
whether Landlord receives any insurance proceeds. However, if the Premises can
be rebuilt within one (1) year after the date of destruction, Landlord may elect
to rebuild the Premises at Landlord's own expense (with all insurance proceeds
being made available to the Landlord to apply against such costs), in which
case, this Sublease shall remain in full force and effect. Landlord shall notify
Tenant of such election within thirty (30) days after the occurrence

                                      -19-
<PAGE>

of total or substantial destruction. If the destruction was caused by an act or
omission of Tenant, Tenant shall pay Landlord the difference between the actual
cost of rebuilding and any insurance proceeds received by Landlord.

7.3 UNINSURED CASUALTY. In the event the Premises are destroyed to the extent of
fifteen percent (15%) or more of the replacement value thereof by any casualty
not covered under the fire and extended coverage insurance covered by Landlord
or Tenant, then Landlord may elect to terminate this Sublease. In the event of
such termination the rights and obligations of the parties hereunder shall
cease. If the Landlord does not elect to so terminate, then the Landlord shall
promptly commence repairing such damage at the Landlord's cost and expense.

7.4 LANDLORD'S OBLIGATIONS. Landlord shall not be required to repair any injury
or damage by fire or other cause, or to make any restoration or replacement of
any panelings, decorations, partitions, railings, floor coverings, office
fixtures or any other improvements or property installed in the Premises by
Tenant or at the direct or indirect expense of Tenant which are not part of the
original Tenant improvements paid for by Landlord. Tenant shall be required to
restore or replace same in the event of damage except for damage caused solely
by the Landlord's negligence or intentional misconduct. Tenant shall have no
claim against Landlord for any damage suffered by reason of any such damage,
destruction, repair or restoration, nor shall Tenant have the right to terminate
this Sublease as the result of any statutory provision now or hereafter in
effect pertaining to the damage and destruction of the Premises, except as
expressly provided herein.

7.5 TEMPORARY REDUCTION IN RENT. If the Premises are destroyed or damaged and
Landlord or Tenant repairs or restores the Premises pursuant to the provisions
of this Article Seven, any rent payable during the period of such damage, repair
and/or restoration shall be reduced by the amount payable under any rental
income insurance paid to Landlord. Except for such possible reduction in
payments required from the Tenant, Tenant shall not be entitled to any
compensation, reduction, or reimbursement from Landlord as a result of any
damage, destruction, repair, or restoration of or to the Premises.

7.6 WAIVER. Tenant waives the protection of any statute, code or judicial
decision which grants a tenant the right to terminate a sublease in the event of
damage or destruction of the premises. Tenant agrees that the provisions of this
Article Seven shall govern the rights and obligations of Landlord and Tenant in
the event of any damage or destruction of the Premises.

                                  ARTICLE VIII
                                  CONDEMNATION

8.1 CONDEMNATION. If all or any portion of the Premises is taken under the power
of eminent domain or sold under the threat of that power (all of which are
called "Condemnation"), this Sublease shall terminate as to the part taken or
sold on the date the condemning authority takes title or possession whichever
occurs first. If more than twenty percent (20%) of the floor area of the
Premises is taken, either Landlord or Tenant may terminate this Sublease as of
the date the condemning authority take title or possession, by delivering
written notice to the other within ten (10) days after receipt of written notice
of such taking (or in the absence of such

                                      -20-
<PAGE>

notice, within ten (10) days after the condemning authority takes possession).
If more than twenty percent (20%) of all subleaseable space in the building in
which the Premises are located is taken the Landlord may elect to terminate this
Sublease by delivering such notice to Tenant. If neither Landlord nor Tenant
terminates this Sublease, this Sublease shall remain in effect as to the portion
of the Premises not taken, except that the Base Rent shall be reduced in
proportion to the reduction in the floor area of the Premises. Any Condemnation
award or payment shall be distributed in the following order: (a) first, to any
ground lessor, mortgagee or beneficiary under a deed of trust encumbering the
Premises, the amount of its interest in the Premises and the Tenant hereby
assigns any other rights which the Tenant may have now or in the future to any
other award to the Landlord; (b) second, to Tenant, only the amount of any award
specifically designated for loss of or damage to Tenant's trade fixtures or
removable personal property, and the Tenant hereby assigns any other rights
which the Tenant may have now or in the future to any other award to the
Landlord, and (c) third, to Landlord, the remainder of such award, whether as
compensation for reduction in the value of the subleasehold, the taking of the
fee, or otherwise. If this Sublease is not terminated, Landlord shall repair any
damage to the Premises caused by the Condemnation, except that Landlord shall
not be obligated to repair any damage for which Tenant has been reimbursed by
the condemning authority. If the severance damages received by Landlord are not
sufficient to pay for such repair, Landlord shall have the right to either
terminate this Sublease or make such repair at Landlord's expense.

                                   ARTICLE IX
                            ASSIGNMENT AND SUBLETTING

9.1 LANDLORD'S CONSENT REQUIRED. No portion of the Premises or of Tenant's
interest in this Sublease may be acquired by any other person or entity, whether
by assignment, mortgage, sublease, transfer, operation of law, or act of Tenant,
without Landlord's prior written consent, except as provided in Section 9.2
below. Any attempted transfer without consent shall be void and shall constitute
a noncurable breach of this Sublease. If tenant is a partnership, (i) any
cumulative transfer or more than twenty percent (20%) of the partnership
interests, or (ii) the admission of a new general partner, or (iii) the transfer
of any interest of any general partner in the partnership shall require
Landlord's consent.

9.2 TENANT AFFILIATE. Tenant may assign this Sublease or sublease the Premises,
without Landlord's consent, to any corporation which controls, is controlled by
or is under common control with Tenant, or to any corporation resulting from the
merger of or consolidation with Tenant ("Tenant's Affiliate"). In such case, any
Tenant's Affiliate shall assume in writing all of Tenant's obligations under
this Sublease, but the Tenant shall remain primarily liable hereunder.

9.3 NO RELEASE OF TENANT. No transfer permitted by this Article Nine, whether
with or without Landlord's consent, shall release Tenant or change Tenant's
primary liability to pay the rent and to perform all other obligations of Tenant
under this Sublease. Landlord's acceptance of rent from any other person is not
a waiver of any provision of this Article Nine. Consent to one transfer is not a
consent to any subsequent transfer. If Tenant's transferee defaults under this
Sublease, Landlord may proceed directly against Tenant without pursuing remedies
against the transferee. Landlord may consent to subsequent assignments or

                                      -21-
<PAGE>

modifications of this Sublease by Tenant's transferee, without notifying Tenant
or obtaining its consent. Such action shall not relieve Tenant's liability under
this Sublease.

9.4 LANDLORD'S ELECTION Tenant's request for consent to any transfer described
in Section 9.1 above shall be accompanied by a written statement setting forth
the details of the proposed transfer, including the name, business and financial
condition of the prospective transferee, financial details of the proposed
transfer (e.g., the term of and rent and security deposit payable under any
assignment or sublease), and any other information Landlord deems relevant.
Landlord shall have the right (a) to withhold consent, if reasonable; (b) to
grant consent; or (c) if the transfer is a sublease of the Premises or an
assignment of this Sublease, to terminate this Sublease as of the effective date
of such sublease or assignment, in which case Landlord may elect to enter into a
direct sublease with the proposed assignee or subtenant.

9.5 NO MERGER. No merger shall result from Tenant's sublease of the Premises
under this Article Nine, Tenant's surrender of this Sublease or the termination
of this Sublease in any other manner. In any such event, Landlord may terminate
any or all subtenancies or succeed to the interest of Tenant as sublandlord
thereunder.

                                   ARTICLE X
                               DEFAULTS; REMEDIES

10.1 COVENANTS AND CONDITIONS. Tenant's performance of each of Tenant's
obligations under this Sublease is a condition as well as a covenant. Tenant's
right to continue in possession of the Premises is conditioned upon such
performance. Time is of the essence in the performance of all covenants and
conditions

10.2 DEFAULTS. Tenant shall be in material default under this Sublease:

      10.2.1 VACATION OR ABANDONMENT. If Tenant abandons or vacates the Premises
or if such abandonment or vacation of the Premises results in the cancellation
of any insurance described in Section 4.4; or

      10.2.2 FAILURE TO PAY. If Tenant fails to pay rent or any other charge
required to be paid to Tenant, as and when due; or

      10.2.3 FAILURE TO PERFORM. If Tenant fails to perform any of Tenant's
nonmonetary obligations under this Sublease for a period of fifteen (15) days
after written notice from Landlord; provided that if more time is required to
complete such performance, Tenant shall not be in default if Tenant commence
such performance within the fifteen (15) day period and thereafter diligently
pursues its completion. However, Landlord shall not be required to give such
notice if Tenant's failure to perform constitute a non-curable breach of this
Sublease. The notice required by this Subsection is intended to satisfy any and
all notice requirements imposed by law on Landlord and is not in addition to any
such requirement.

      10.2.4 OTHER DEFAULTS. (i) If Tenant makes a general assignment or general
arrangement for the benefit of creditors; (ii) If a petition for adjudication of
bankruptcy or for

                                      -22-
<PAGE>

reorganization or rearrangement is filed by or against Tenant and is not
dismissed within thirty (30) days; (iii) if a trustee or receiver is appointed
to take possession of substantially all of Tenant's assets located at the
Premises or of Tenant's interest in this Sublease and possession is not restored
to Tenant within thirty (30) days; or (iv) if substantially all of Tenant's
assets located at the Premises or of Tenant's interest in this Sublease is
subjected to attachment, execution or other judicial seizure which is not
discharged within thirty (30) days. If a court of competent jurisdiction
determines that any of the acts described in this Subsection 10.2.4 is not
default under this Sublease, and a trustee is appointed to take possession (or
if Tenant remains a debtor in possession) and such trustee or Tenant transfers
Tenant's interest hereunder, then Landlord shall receive as Additional Rent, the
difference between the rent (or any other consideration) paid in connection with
such assignment or sublease and the rent payable by Tenant hereunder.

10.3 REMEDIES. On the occurrence of any material default by Tenant, Landlord
may, at any time thereafter, with or without notice or demand and without
limiting Landlord in the exercise of any right or remedy which Landlord may
have:

      10.3.1 TERMINATION OF POSSESSION. Terminate Tenant's right to possession
of the Premise by any lawful means, in which case this Sublease shall terminate
and Tenant shall immediately surrender possession of the Premises to Landlord.
In such event Landlord shall have the immediate right to re-enter and remove all
persons and property and such property may be removed and stored in a public
warehouse or elsewhere at the cost of, and for the account of Tenant, all
without service of notice of resort to legal process and without being deemed
guilty of trespass, or becoming liable for any loss or damage which may be
occasioned thereby; and Landlord shall be entitled to recover from Tenant all
damages incurred by Landlord by reason of Tenant's default, including (i) the
worth at the time of the award of all Base Rent, Additional Rent and other
charges which were earned or were payable at the time of the termination; (ii)
the worth at the time of the award of the amount by which the unpaid Base Rent,
Additional Rent and other charges which would have been earned or were payable
after termination until the time of the award exceeds the amount of such rental
loss 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, Additional
Rent and other charges which would have been payable for the balance of the term
after the time of award exceeds the amount of such rental loss that Tenant
proves could have been reasonably avoided; and (iv) any other amount necessary
to compensate Landlord for all the detriment proximately caused by Tenant's
failure to perform its obligations under the Sublease or which in the ordinary
course of things would be likely to result therefrom, including, but not limited
to, any cost or expenses incurred by Landlord in maintaining or preserving the
Premises after such default, the cost of recovering possession of the Premises,
expenses of reletting, including necessary renovation or alteration of the
Premises, Landlord's reasonable attorneys fees incurred in connection therewith,
and any real estate commissions or other such fees paid or payable. As used in
subparts (i) and (ii) above, the "worth at the time of the award" is computed by
allowing interest on unpaid amounts at the rate of fifteen percent (15%) per
annum, or such lesser amount as may then be the maximum lawful rate. As used in
subpart (iii) above, the "worth at the time of the award" is computed by
discounting such amount at the discount rate of the Federal Reserve Bank of San
Francisco at the time of the award, plus one percent (1%). If Tenant shall have
abandoned the Premises, Landlord shall have the option of (i)

                                      -23-
<PAGE>

retaking possession of the Premises and recovering from Tenant the amount
specified in this Subsection 10.3.1 or (ii) proceeding under Subsection 10.3.2.

      10.3.2 MAINTENANCE OF POSSESSION. Maintain Tenant's right to possession,
in which case this Sublease shall continue in effect whether or not Tenant shall
have abandoned the Premises. In such event, Landlord shall be entitled to
enforce all of Landlord's rights and remedies under this Sublease including the
right to recover the rent as it becomes due hereunder.

      10.3.3 OTHER REMEDIES. Pursue any other remedy now or thereafter available
to Landlord under the laws or judicial decisions of the state in which the
Premises is located.

10.4 THE RIGHT TO RELET THE PREMISES. Should Landlord elect to re-enter, as
herein provided, or should it take possession pursuant to legal proceedings or
pursuant to any notice provided for by law, it may either terminate this
Sublease or it may from time to time without terminating this Sublease, make
such alterations and repairs as may be necessary in order to relet the property,
and relet said property or any part thereof for such term or terms (which may be
for a term extending beyond the term of this Sublease) and at such rental or
rentals and upon such other terms and conditions as Landlord in its sole
discretion may deem advisable upon each such reletting all rentals received by
the Landlord from such reletting shall be applied, first to the repayment of any
indebtedness other than rent due hereunder from Tenant to Landlord; second, to
the payment of any costs and expenses of such reletting, including brokerage
fees and attorneys' fees and of costs of such alterations and repairs; third, to
the payment of rent due and unpaid hereunder, and the residue, if any, shall be
held by Landlord and applied in payment of future rent as the same may become
due and payable hereunder. If such rentals received from such reletting during
any month are less than that to be paid during that month by Tenant hereunder,
Tenant shall pay any such deficiency to Landlord. Such deficiency shall be
calculated and paid monthly. No such re-entry or taking possession of said
property by Landlord shall be construed as an election on its part to terminate
this Sublease unless a written notice of such intention be given to Tenant or
unless the termination thereof be decree by a court of competent jurisdiction.

10.5 WAIVER OF RIGHTS OF REDEMPTION. Tenant hereby expressly waives any and all
rights of redemption granted by or under any present or future laws in the event
of Tenant being evicted or dispossessed for any cause, or in the event of
Landlord obtaining possession of the Premises, by reason of the violation by
Tenant of any of the covenants or conditions of this Sublease, or otherwise.

10.6 CUMULATIVE REMEDIES. Landlord's exercise of any right or remedy shall not
prevent it from exercising any other right or remedy.

                            PROTECTION OF CREDITORS

11.1 SUBORDINATION

      11.1.1 LANDLORD'S ELECTION. This Sublease is and shall remain subordinate
to the Master Lease. In addition, Landlord shall have the right to require
Tenant to subordinate this Sublease to any other ground lease, deed of trust or
mortgage encumbering the Premises, any advances made on the security thereof and
any renewals, modifications, consolidations, replacements or extensions thereof
whenever made or recorded. However, Tenant's right to quiet possession of the
Premises during the Sublease Term shall not be disturbed if Tenant pays the rent
and performs all of Tenant's obligations under this Sublease and is not
otherwise in default. If any ground lessor, beneficiary or mortgagee elects to
have this Sublease prior to the lien of its ground sublease, deed of trust or
mortgage and gives written notice thereof to Tenant, this Sublease shall be
deemed prior to such ground sublease, deed of trust or mortgage whether this
Sublease is dated prior or subsequent to the date of said ground sublease, deed
of trust or mortgage or the date of recording thereof.

      11.1.2 ADDITIONAL DOCUMENTS. Tenant agrees to execute any documents
required to effectuate such subordination or to make this sublease prior to the
lien of any ground sublease, mortgage or deed of trust, as the case may be, and
failing to do so within ten (10) days after written demand does hereby make,
constitute and irrevocably appoint Landlord as Tenant's attorney-in-fact and in
Tenant's name, place and stead, to do so.

      11.2 ATTORNMENT. If Landlord's interest in the Premises is acquired by any
ground lessor, beneficiary, under a deed of trust, mortgagee, or purchaser at a
foreclosure sale, Tenant shall attorn to the transferee of or successor to
Landlord's interest in the Premises and recognize such transferee or successor
as Landlord under this Sublease. Tenant waives the protection of any statute or
rule of law which gives or purports to give Tenant any right to terminate this
Sublease or surrender possession of the Premises upon the transfer of Landlord's
interest.

      11.3 SIGNING OF DOCUMENTS. Tenant shall sign and deliver any instrument or
documents necessary or appropriate to evidence any such attornment or
subordination or agreement to do so. If Tenant fails to do so within (10) days
after written request, Tenant hereby makes, constitutes and irrevocably appoints
Landlord, or any transferee or successor of Landlord, the attorney-in-fact of
Tenant to execute and deliver any such instrument or document.

11.4 ESTOPPEL CERTIFICATES.

      11.4.1 LANDLORD'S REQUEST. Upon Landlord's written request, Tenant shall

they have been changed, stating how they have been changed); (ii) that this
Sublease has not been cancelled or terminated; (iii) the last date of payment of
the Base Rent and other charges and the time period covered by such payment; and
(iv) that Landlord is not in default under this sublease (or, if the Landlord is
claimed to be in default, stating why). Tenant shall deliver such statement to
Landlord within ten (10) days after Landlord's request. Any such statement by
Tenant may be given by Landlord to

                                      -25-
<PAGE>

any prospective purchaser or encumbrancer of the Premises. Such purchaser or
encumbrancer may rely conclusively upon such statement as true and correct.

      11.4.2 FAILURE TO DELIVER. If Tenant does not deliver such statement to
Landlord within such ten (10) day period, Landlord, and any prospective
purchaser or encumbrancer, may conclusively presume and rely upon the following
facts except as otherwise represented: (i) that the terms and provisions of this
Sublease have not been changed resented by Landlord; (ii) that this Sublease has
not been cancelled or terminated except as otherwise represented by Landlord;
(iii) that not more than one month's Base Rent or other charges have been paid
in advance; and (iv) that Landlord is not in default under the Sublease. In such
event, Tenant shall be estopped from denying the truth of such facts.

11.5 TENANT'S FINANCIAL CONDITION. Within ten (10) days after written request
from Landlord, Tenant shall deliver to Landlord such financial statements as are
reasonably required by Landlord to verify the net worth of Tenant, or any
assignee, subtenant, or guarantor of Tenant. In addition, Tenant shall deliver
to any lender or proposed purchaser of the Premises designated by Landlord any
financial statements required by such lender to facilitate the sale, financing
or refinancing of the Premises. Tenant represents and warrants to Landlord that
(a) each such financial statement is a true and accurate statement as of the
date of such statement and (b) at all times after the date of any such statement
during the Sublease Term or any extension thereof, Tenant's net worth, as stated
therein, shall not be reduced. All financial statements shall be confidential
and shall be used only for the purposes set forth herein.

                                  ARTICLE XII
                                   LEGAL COSTS

12.1 LEGAL PROCEEDINGS. Tenant or Landlord shall reimburse the other party, upon
demand, for any costs or expense incurred by the other party in connection with
any breach or default of Tenant or Landlord under this Sublease, whether or not
suit is commenced or judgment entered. Such costs shall include legal fees and
costs incurred for the negotiation of a settlement, enforcement of rights or
otherwise. Furthermore, if any action for breach of or to enforce the provisions
of this Sublease is commenced, the court in such action shall award to the party
in whose favor a judgment is entered a reasonable sum as attorneys' fees and
costs. Such attorneys' fees and costs shall be paid by the losing party in such
action. Tenant shall also indemnify Landlord against and hold Landlord harmless
from all costs, expenses, demands and liability incurred by Landlord if Landlord
becomes or is made a party to any claim or action (a) instituted by Tenant or by
any third party against Tenant, or by or against any person holding any interest
or using the Premises by license of or agreement with Tenant; (b) for
foreclosure of any lien for labor or material furnished to or for Tenant or such
other person; (c) otherwise arising out of or resulting from any act or
transaction of Tenant or such other person; or (d) necessary to protect
Landlord's interest under this Sublease in a bankruptcy proceeding, or other
proceeding under Title 11 of the United States Code, as amended. Tenant shall
defend Landlord against any such claim or action at Tenant's expense with
counsel reasonably acceptable to Landlord or, at Landlord's election, Tenant
shall reimburse Landlord for any legal fee or costs incurred by Landlord in any
such claim or action.

                                      -26-

12.2 LANDLORD'S CONSENT. Tenant shall pay Landlord's reasonable attorneys' fees
incurred in connection with Tenant's request for Landlord's consent under
Article Nine (Assignment and Subletting) or in connection with any other act
which Tenant proposes to do and which requires Landlord's consent, provided,
however, such attorney's fees shall not exceed $2,500.

                                  ARTICLE XIII
                            MISCELLANEOUS PROVISIONS

13.2  LANDLORD'S LIABILITY; CERTAIN DUTIES.

      13.2.1 LANDLORD. As used in this Sublease, the term "Landlord" means only
the current owner or owners of the leasehold estate under the Master Lease at
the time in question. Each Landlord has obligated to perform the obligations of
Landlord under this Sublease only during the time such Landlord owns such
interest or title. Any Landlord who transfers its title or interest is relieved
of all liability with respect to the obligations of Landlord under this Sublease
to be performed on or after the date of transfer. However, each Landlord shall
deliver to its transferee all funds previously paid by Tenant, if such funds
have not yet been applied under the terms of this Sublease.

      13.2.2 WRITTEN NOTICE. Tenant shall give written notice of any failure by
Landlord to perform any of its obligations under this Sublease to Landlord and
to the District, any ground lessor, mortgagee or beneficiary under any deed of
trust encumbering the Premises whose name and address have been furnished to
Tenant in writing. Landlord shall not be in default under this Sublease unless
Landlord (or the District, or such ground lessor, mortgagee or beneficiary)
fails to cure such non-performance within thirty (30) days after receipt of
Tenant's notice. However, if such non-performance reasonably requires more than
thirty (30) days to cure, Landlord shall not be in default if such cure is
commenced within such thirty (30) day period and thereafter diligently pursued
to completion.

13.3 SEVERABILITY. A determination by a court of competent jurisdiction that any
provision of this Sublease or any part thereof is illegal or unenforceable shall
not cancel or invalidate the remainder of such provision or this Sublease, which
shall remain in full force and effect.

13.4 INTERPRETATION. The captions of the Articles or Sections of this Sublease
are to assist the parties in reading this Sublease and are not a part of the
terms or provisions of this Sublease. Whenever required by the context of this
Sublease, the singular shall include the plural and the plural shall include the
singular. The masculine, feminine and neuter genders shall each include the
other. In any provision relating to the conduct, acts or omissions of tenant,
the term "Tenant" shall include Tenant's agents, employees, contractors,
invitees, successors or others using the Premises with Tenant's expressed or
implied permission.

13.5 INCORPORATION OF PRIOR AGREEMENTS; MODIFICATIONS. This Sublease is the only
agreement between the parties pertaining to the sublease of the Premises and

                                      -27-
<PAGE>

no other agreements are effective. All amendments to this Sublease shall be in
writing and signed by all parities. Any other attempt at amendment shall be
void.

13.6 NOTICES. All notices required or permitted under this Sublease shall be in
writing and shall be personally delivered or sent by certified mail, return
receipt requested, postage prepaid. Notices to Tenant shall be delivered to the
address specified in Section 1.3 above, except that upon Tenant's taking
possession of the Premises, the Premises shall be Tenant's address for notice
purposes. Notice to Landlord shall be delivered to the address specified in
Section 1.2 above. All notices shall be effective upon personal delivery or
three (3) days after deposit in the U.S. Mail. Either party may change its
notice address upon written notice to the other party.

13.7 WAIVERS. All waivers must be in writing and signed by the waiving party.

of rent shall not be a waiver and shall not prevent Landlord from enforcing that
provision or any other provision of this Sublease in the future. No statement on
a payment check from Tenant or in a letter accompanying a payment check shall be
binding on Landlord. Landlord may with or without notice to Tenant, negotiate
such check without being bound to the conditions of such statement.

13.8 NO RECORDATION. Tenant shall not record this Sublease without prior written
consent from Landlord. However, Landlord may require that a "Short Form"
memorandum of this Sublease be executed by both parties and recorded.

13.9 BINDING EFFECT; CHOICE OF LAW. This Sublease binds any party who legally
acquires any rights or interest in this Sublease from Landlord or Tenant.
However, Landlord shall have no obligation to Tenant's successor unless the
rights or interests of Tenant's successor are acquired in accordance with the
terms of this Sublease. The laws of the state in which the Premises are located
shall govern this Sublease.

each person signing this Sublease on behalf of Tenant represents and warrants
that he has full authority to do so and that this Sublease binds the
corporation. Within five (5) days after this Sublease is signed, Tenant shall

rent or other charges due from Tenant or to cure any other defaults of Tenant.
Tenant hereby waives the provisions of Section 1950.7 of the California Civil
Code, and all other provisions of law, now or hereafter in force, which provide
that Landlord may claim from a security deposit only those sums reasonably
necessary to remedy defaults in the payment of rent, to repair damage caused by
Tenant or to clean the Premises, it being agreed that Landlord may, in addition,
claim those sums reasonably necessary to compensate Landlord for any other loss
or damage, foreseeable or unforeseeable, caused by the act or omission of Tenant
or any officer, employee, agent or invitee of Tenant. If Landlord uses any part
of the Security Deposit, Tenant shall restore the Security Deposit to its full
amount within ten (10) days after Landlord's written request. Tenant's failure
to do so shall be a material default under this Sublease. No interest shall be
paid on the Security Deposit. Landlord shall not be required to keep the
Security Deposit separate from its other accounts and no trust relationship is

adjustment shall be made concerning advance Rent, any other advance payments
made by Tenant to Landlord, and accrued Real Property Taxes, and Landlord shall
refund the unused portion of the Security Deposit to Tenant or Tenant's
successor.

                                   ARTICLE IV

number of square feet in the Premises bears to the total number of leasable
square feet in the Project existing upon the date the computation is made. Each
year Landlord shall notify Tenant of Landlord's calculation of Tenant's
proportionate share of the Real Property Taxes and together with such notice
shall furnish Tenant with a copy of the tax bill. If any supplemental tax bills
are delivered with respect to the Project, Landlord may notify Tenant of
Landlord's new calculation of Tenant's proportionate share of Real Property
Taxes as soon as such supplemental tax bill is received. Subject to Section 4.8
below, Tenant shall reimburse Landlord for Tenant's proportionate share of Real
Property Taxes semiannually no later than fifteen (15) days before the taxing
authority's delinquency date.

                                      -4-
<PAGE>

      4.2.2 DEFINITION OF "REAL PROPERTY TAXES". "Real Property Taxes" means (i)
any fee, license fee, license tax, commercial rental tax, levy, charge,
assessment, penalty or tax (other than inheritance or estate taxes) imposed by
any authority having the direct or indirect power to tax, including any City,
County, State or Federal government, or any school, agriculture, lighting,
drainage or other improvement district thereof, as against any legal or
equitable interest of Landlord in the Premises; (ii) any tax on the Landlord's
right to receive, or the receipt of, rent or income from the Premises or against
Landlord's business of leasing the Premises; (iii) any tax or charge for fire
protection, streets, sidewalks, road maintenance, refuse or other services
provided to the Premises by any governmental agency; (iv) any tax imposed upon
this transaction or based upon a reassessment of the Premises due to a change in
ownership or transfer of all or part of Landlord's interest in the Premises; and
(v) any charge or fee replacing any tax previously included within the
definition of Real Property Taxes. "Real Property Taxes" does not, however,
include Landlord's Federal or State income, franchise, inheritance or estate
taxes.

      4.2.3 PERSONAL PROPERTY TAXES.

            (a) Tenant shall pay prior to delinquency all taxes charged against
trade fixtures, furnishings, equipment or any other personal property belonging
to Tenant. Tenant shall attempt to have such personal property taxed separately
from the Premises.

            (b) If any such taxes on Tenant's personal property are levied
against Landlord or Landlord's property, or if the assessed value of the
Premises is increased by the inclusion therein of a value placed upon such
personal property or trade fixtures of Tenant, then Landlord, after written
notice to Tenant, shall have the right to pay the taxes based upon such
increased assessments, regardless of the validity thereof, but only under proper
protest if requested by Tenant in writing. If Landlord shall do so, then Tenant
shall, upon demand, repay to Landlord the taxes levied against Landlord, or the
proportion of such taxes resulting from such increase in the assessment. In any
such event, however, Tenant, at Tenant's sole cost and expense, shall have the
right, in the name of Landlord and with Landlord's cooperation, to bring suit in
any court of competent jurisdiction to recover the amount of any such taxes so
paid under protest; any amount so recovered to belong to the Tenant.

            (c) If any of Tenant's personal property is taxed with the Premises,
Tenant shall pay Landlord the taxes for the personal property within fifteen
(15) days after Tenant receives a written statement from Landlord for such
personal property taxes.

4.3 UTILITIES. Tenant shall arrange for and pay, directly to the appropriate
supplier, the cost of all natural gas, heat, light, power, sewer, telephone,
water and other utilities and services supplied to the Premises. Landlord will
cooperate in attempting to have each of the utilities supplied to the Premises
separately metered. However, if any such utilities or services are jointly
metered with other premises within the Project, Landlord shall make a reasonable
determination of Tenant's proportionate share of the cost for such utilities and
services, based on information reasonably available to Landlord, and Tenant
shall pay such share to Landlord within fifteen (15) days after receipt of
Landlord's written statement of such cost.

4.4   INSURANCE.

      4.4.1 LANDLORD'S LIABILITY INSURANCE. During the Sublease Term, Landlord
shall maintain a policy of commercial general liability insurance at Tenant's
expense, insuring Landlord against liability arising out of the ownership, use,
occupancy or maintenance of the Premises. The initial amount of such insurance
shall be at least $2,000,000.00 and shall be subject to periodic increase based
upon inflation, increased liability awards, recommendations of professional
insurance advisers, and other relevant factors. However, the amount of such
insurance shall not limit Tenant's liability nor relieve Tenant or any
obligation hereunder. Tenant shall, at Tenant's expense, maintain such other
liability insurance as required pursuant to Subsections 4.4.6 and 4.4.7 hereof.

      4.4.2 LANDLORD'S HAZARD AND RENTAL INCOME INSURANCE. During the Sublease
Term, Landlord shall, at Tenant's expenses, maintain policies of insurance
covering loss of or damage to the Premises to the extent of at least one hundred
percent (100%) of its replacement value. Such policies shall provide protection
against all perils included within the classification of fire, extended
coverage, vandalism, malicious mischief, and any other perils which Landlord
reasonably deems necessary. Landlord may obtain insurance coverage for Tenant's
fixtures, equipment or building improvements installed by Tenant in or on the
Premises. Tenant shall, at Tenant's expense, maintain such primary or additional
insurance on its fixtures, equipment and building improvements as is required
pursuant to Subsections 4.4.6 and 4.4.7 hereof. During the Sublease Term,
Landlord may also maintain a rental income insurance policy at Tenant's expense,
with loss payable to Landlord in an amount equal to one year's Rent. Tenant
shall not do or permit to be done anything which invalidates any such insurance
policies.

      4.4.3 PAYMENT OF PREMIUMS; INSURANCE POLICIES. Tenant shall pay its pro
rata share of the premiums for maintaining the insurance required by Subsections
4.4.1 and 4.4.2. Tenant's pro rata share of all such premiums shall be based on
the same proportion as used for payment of taxes pursuant to Subsection 4.2.1
hereof. All such amounts will be due and payable upon ten (10) days written
notice.

      4.4.4 INCREASE IN FIRE INSURANCE PREMIUM. Tenant agrees that it will not
keep, use, manufacture, assemble, sell or offer for sale in or upon the Premises
any article which may be prohibited by the standard form of fire insurance
policy. Tenant agrees to pay any increase in premiums for fire and extended
coverage insurance that may be charged during the term of this Sublease on the
amount of such insurance which may be carried by Landlord on said Premises or
the Building, resulting from the acts or omissions of Tenant, its agents,
servants or employees, or the use or occupancy of the Premises by Tenant or from
the type of materials or products stored, manufactured, assembled or sold by
Tenant in the Premises, whether or not Landlord has consented to the same. In
determining whether increased premiums are the result of Tenant's use of the
Premises, a schedule, issued by the organization making the insurance rate on
the Premises, showing the various components of such rate, shall be conclusive
evidence of the several items and charges which make up the fire insurance rate
on the Premises.

      4.4.5 WAIVER OF SUBROGATION. Landlord and Tenant each hereby release and
relieve the other, and waive their entire right to recover damages (whether in
contract or in tort)

                                      -6-
<PAGE>

against the other, for loss or damage arising out of or incident to the perils
required to be insured against under Section 4.4. The effect of such releases
and waivers of the right to recover damages shall not be limited by the amount
of insurance carried or required, or by any deductibles applicable thereto.
Landlord and Tenant agree to have their respective insurance companies issuing
property damage insurance waive any right to subrogation that such companies may
have against Lessor or Lessee, as the case may be, so long as the insurance is
not invalidated thereby.

      4.4.6 TENANT'S REQUIRED INSURANCE. Tenant shall keep in force throughout
the Sublease Term: (a) a commercial general liability insurance policy or
policies to protect the Landlord Entities against any liability to the public or
to any invitee of Tenant or a Landlord Entity incidental to the use of or
resulting from any accident occurring in or upon the Premises with a limit of
not less than $1,000,000.00 per occurrence and not less than $2,000,000.00 in
the annual aggregate, or such larger amount as Landlord may prudently require
from time to time, covering bodily injury, personal injury, property damage and
contractual liability and $1,000,000 products/completed operations aggregate;
(b) Business Auto Liability covering owned, non-owned and hired vehicles with a
limit of not less than $1,000,000 per accident; (c) insurance protecting against
liability under Worker's Compensation Laws with limits at least as required by
statute; (d) Employer's Liability with limits of $500,000 each accident,
$500,000 disease policy limit, $500,000 disease - each employee; (e) All Risk or
Special Form coverage protecting Tenant against loss or damage to Tenant's
alterations, additions, improvements, carpeting, floor coverings, paneling,
decorations, fixtures, inventory, and other personal property situated in or
about the Premises to the full replacement value of the property so insured; and
(f) such other reasonable types of insurance and in such reasonable amounts
covering the Premises and operations therein as Landlord may reasonably require
from time to time. The term "Landlord Entities" shall mean Landlord and any
other person or entity that Landlord may designate from time to time.

      4.4.7 REQUIRED INSURANCE POLICIES. Each of the policies required under
Section 4.4.6 shall (a) be provided at Tenant's expense; (b) name the Landlord
Entities as additional insureds; (c) be issued by an insurance company with a
minimum Best's rating of "A:VII" during the Sublease Term; (d) provide that said
insurance shall not be canceled unless thirty (30) days prior written notice
(ten days for non-payment of premium) shall have been given to Landlord; and (e)
be primary to and not contributory with any similar insurance carried by
Landlord. Said policy or policies or certificates thereof shall be delivered to
Landlord by Tenant upon the Commencement Date and at least thirty (30) days
prior to each renewal of said insurance.

      4.4.8 ADDITIONAL LIABILITY; UNDER CONSTRUCTION. Whenever Tenant shall
undertake any alterations, additions or improvements in, to or about the
Premises ("Work") the aforesaid insurance protection must extend to and include
injuries to persons and damage to property arising in connection with such Work,
together with such other insurance as Landlord shall require; and the policies
of or certificates evidencing such insurance must be delivered to Landlord prior
to the commencement of any such Work.

4.5 COMMON AREAS.

      4.5.1 DEFINITION; LOCATION. As used in this Sublease, "Common Areas" shall
mean all areas within the Project which are available for the common use of
tenants of the Project and which are not leased or held for the exclusive use of
tenants of the Project or which are not leased or held for the exclusive use of
Tenant or other tenants, including, but not limited to, parking areas,
driveways, sidewalks, loading areas, retaining walls, truck service ways,
pedestrian malls, stairs, ramps, restrooms, access roads, corridors,
landscaping, planted areas and trash enclosures. Landlord may from time to time
change the size, location, nature and use of the Common Areas, including
converting Common Areas into leasable areas, construction of additional parking
facilities (including parking structures) in the Common Areas, and increasing or
decreasing Common Area land and/or facilities. Tenant acknowledges that such
activities may result in occasional inconvenience to Tenant from time to time.
Landlord will exercise good faith efforts to minimize any disruption to Tenant's
business caused by such activities, but Tenant hereby releases Landlord from any
and all claims pertaining to such activities.

      4.5.2 USE OF COMMON AREAS. Subject to other provisions of this Sublease,
Tenant shall have the nonexclusive right (in common with other tenants and all
others to whom Landlord has granted or may grant such rights) to use the Common
Areas for the purposes intended, subject to such reasonable rules and
regulations as Landlord may establish from time to time. Tenant shall abide by
such rules and regulations and shall use its best effort to cause others who use
the Common Areas with Tenant's expressed or implied permission to abide by
Landlord's rules and regulations. At any time, Landlord may close any Common
Areas to perform any acts in and to the Common Areas as, in Landlord's judgment,
may be desirable to improve the Project. Tenant shall not, at any time,
intentionally interfere with the rights of Landlord, other tenants, or any other
person entitled to use the Common Areas.

      4.5.3 VEHICLE PARKING. Tenant shall be entitled to use 3.8 vehicle parking
spaces in the Project for each 1,000 (One Thousand) square feet (a total of
thirty-one (31) spaces) within the Premises without paying any additional rent.
Tenant's parking shall not be reserved and shall be limited to vehicles no
larger than standard size automobiles or pickup or utility vehicles. Tenant
shall not cause large trucks or other large vehicles to be parked within the
Project. Vehicles shall be parked only in striped parking spaces and not in
driveways, loading areas or other locations not specifically designated for
parking. If Tenant parks more vehicles in the parking area than the number
identified herein, such conduct shall be a material breach of this Sublease. No
vehicle may be parked at the Project for more than seventy-two (72) consecutive
hours without Landlord's prior written consent.

      4.5.4 MAINTENANCE OF COMMON AREAS. Landlord shall maintain the Common
Areas in good order, condition and repair and shall operate the Project, in
Landlord's reasonable discretion, as a first class industrial/commercial real
property development. Tenant shall pay Tenant's pro rata share (as defined
below) of all costs incurred by Landlord in connection with the ownership,
operation and maintenance of the Common Area ("Common Area Costs"). Common Area
Costs include, but are not limited to, costs and expenses for the following:
gardening and landscaping; pest control and extermination services; utilities,
water and sewage charges; maintenance of signs (other than Tenant's signs);
premiums for liability,

                                      -8-
<PAGE>

property damage, fire and other types of casualty insurance on the Common Areas
and all Common Area improvements; all personal property taxes levied on or
attributable to personal property used in connection with the Common Areas;
straight-line depreciation on personal property owned by Landlord which is
consumed in the operation or maintenance of the Common Areas; fees for required
licenses and permits; repairing, resurfacing, repaving, maintaining, painting,
lighting, cleaning, refuse removal, security and similar items; reserves; and a
reasonable allowance to Landlord for Landlord's supervision of the Common Areas
(not to exceed five percent (5%) of the total of all other Common Area Costs for
the calendar year). Landlord may cause any or all of such services to be
provided by third parties, or by entities associated with Landlord. Common Area
Costs shall not include depreciation of real property which forms part of the
Common Area, all Real Property Taxes for which Tenant is liable under this
Sublease, all insurance premiums for which Tenant is liable under this Sublease,
and all maintenance and repair costs for which Tenant is liable under this
Sublease.

      4.5.5 TENANT'S SHARE AND PAYMENT. Tenant shall pay Tenant's annual pro
rata share of all estimated Common Area Costs, in advance, in monthly
installments on the first day of each month during the Sublease Term (prorated
for any fractional month). Tenant's pro rata share shall be calculated by
dividing the square foot area of the Premises, as set forth in Section 1.4 of
this Sublease, by the aggregate square foot area of the leasable area within the
Project whether currently leased or not upon the date the computation is made.
Landlord may adjust such estimates at any time and from time to time based upon
Landlord's experience and reasonable anticipation of costs. Such adjustments
shall be effective as of the next Rent payment date after notice to Tenant.
Within thirty (30) days after the end of each calendar year of the Sublease
Term, Landlord shall deliver to Tenant a statement prepared in accordance with
generally accepted accounting principles setting forth, in reasonable detail,
the actual Common Area Costs paid or incurred by Landlord during the preceding
calendar year and Tenant's pro rata share. Upon receipt of such statement, there
shall be an adjustment between Landlord and Tenant with payment to or credit
given by Landlord (as the case may be) so that Landlord shall receive the entire
amount of Tenant's share of such costs and expenses for such period. Any delay
or failure of Landlord to deliver such statement within said thirty (30) day
period will not constitute a waiver of Landlord's right to subsequently deliver
such statement and require Tenant to pay any deficiency in Tenant's pro rata
share as may be disclosed by such statement. Tenant shall have the right to
audit the Common Area Costs billed to Tenant by Landlord. The cost of the audit
shall be the responsibility of and paid by Tenant, unless the Common Area Costs
billed to Tenant by Landlord exceed actual costs as verified by the audit by
more than five (5) percent, in which case the cost of the audit shall be paid by
Landlord.

            4.5.5.1 ALTERNATIVE PAYMENT. Notwithstanding the foregoing, Landlord
has the right to notify Tenant on a monthly or other basis of the actual amount
Landlord has expended for all Common Area Costs incurred during the previous
month or period. Such notice shall also set forth Tenant's pro rata share of
such actual costs. Upon receipt of such statement, Tenant shall pay with the
next monthly installment of Rent Tenant's pro rata share of the actual Common
Area Costs incurred during the previous month or period.

      4.5.6 ADDITIONAL AREAS. In addition to the Common Areas and costs
associated therewith described in this Section 4.5, Landlord may, but is not
obligated to, provide certain

                                      -9-
<PAGE>

additional spaces and areas within or in close proximity to the Project
("Additional Areas") as (and included within the definition of) Common Areas.
The Additional Areas may include, but are not limited to, an office used by and
subject to the exclusive control of Landlord for leasing and/or managing the
Project, a conference room available on a reserved basis for use by tenants
within the Project during normal business hours, maintenance facilities for the
storage of equipment and supplies, and a locker room facility for use by tenants
of the Project and their employees that are employed at the Project. Common Area
Costs for which Tenant is liable for its pro rata share as described in Section
4.5.4 shall include costs of operating and the reasonable rental value of the
space occupied by the Additional Areas. Notwithstanding anything to the contrary
herein, Landlord agrees to make the conference Room Locker/shower facilities
available to Tenant throughout the initial term of the sublease.

4.6 LATE CHARGES. Tenant's failure to pay Rent promptly may cause Landlord to
incur unanticipated costs. The exact amount of such costs is impractical or
extremely difficult to ascertain. Such costs may include, but are not limited
to, processing and accounting charges and late charges which may be imposed on
Landlord by any ground lease, mortgage or trust deed encumbering the Premises.
Therefore, if Landlord does not receive any Rent payment within five (5)
business days after it becomes due, Tenant shall pay Landlord a late charge
equal to five percent (5%) of the overdue amount. The parties agree that such
late charge represents a fair and reasonable estimate of the costs Landlord will
incur by reason of such late payment.

      4.6.1 REPEATED LATE CHARGES. In the event that a late charge is payable
under this Sublease, whether or not collected, for four (4) installments of Base
Rent during any one calendar year of the Sublease Term, then the Base Rent shall
automatically become due and payable quarterly in advance, rather than monthly.
All moneys paid to Landlord under this provision may be commingled with other
moneys of Landlord and shall not bear interest.

4.7 INTEREST ON PAST DUE OBLIGATIONS. Any amount owed by Tenant to Landlord

rate then permitted by law, whichever is less, from the due date of such amount
(the "Interest Rate"). However, interest shall not be payable on late chares to
be paid by Tenant under this Sublease.

4.8 IMPOUNDS FOR INSURANCE PREMIUMS AND REAL PROPERTY TAXES. If requested by any
ground lessor or lender to whom Landlord has granted a security interest in the
Premises or the Project, or if Landlord deems it necessary in Landlord's sole
and absolute discretion, of if Tenant is more than ten (10) business days late
in the payment of Rent more than once in any consecutive twelve (12) month
period, Tenant shall pay Landlord a sum equal to one-twelfth (1/12) of the
annual Real Property Taxes and/or insurance premiums payable by Tenant under
this Sublease (the "Impound Payments"), together with each payment of Base Rent.
The Impound Payments shall be paid to the ground lessor or lender if required or
held by Landlord with no obligation to pay Tenant interest thereon or keep the
Impound Payments in a separate account. The amount of the Real Property Taxes
and insurance premiums when unknown shall be reasonably estimated by Landlord.
The Impound Payments shall be applied by Landlord to the payment of Real
Property Taxes and insurance premiums when due. Any

                                      -10-

deficiency of Impound Payments shall be paid by Tenant to Landlord upon
written request. If Tenant defaults under this Sublease, Landlord may apply the
Impound Payments to any obligation then due under this Sublease.

any Hazardous Material (as hereinafter defined) to be brought upon, kept or used
in or about the Premises or the Project in violation of this sublease or any
applicable laws by Tenant, its agents, employees, contractors or invitees, other
than those expressly permitted by Landlord in writing. If Tenant breaches the
obligation stated in the preceding sentence, or if the presence of Hazardous
Materials on the Premises caused or permitted by Tenant (including Hazardous
Materials specifically permitted by Landlord) results in contamination of the
Premises or the Project, or if contamination of the Premises or the Project by
Hazardous Material otherwise occurs for which Tenant is legally liable to
Landlord for damage resulting therefrom, Tenant shall indemnify, defend and hold
the Landlord Entities harmless from and against any and all claims, judgments,
damages, penalties, fines, costs, liabilities, or losses (including without
limitation diminution in value of the Premises or any portion of the Project,
damages for the loss or restriction on use of rentable or usable space or of any
amenity of the Premises of the Project, damages arising from any adverse impact
on marketing of space in the Premises or the Project due to Tenant's breach of

of the Landlord

                                      -12-

with any investigation of site conditions or any cleanup, remedial, removal, or
restoration work required by any federal, state or local governmental agency or
political subdivision because of Hazardous Material present in the soil or
ground water on or under the Premises. Without limiting the foregoing, if the
presence of any Hazardous Material on the Premises caused or permitted by Tenant
results in any contamination of the Premises or the Project, Tenant shall
promptly take all actions at its sole expense as are necessary to return the
Premises or the Project, as applicable, to the condition existing prior to the
introduction of any such Hazardous Material to the Premises or the Project, as
applicable, provided that Landlord's approval of such action shall first be
obtained, which approval shall not be unreasonably withheld so long as such
actions would not potentially have any material adverse long-term or short-term
effect on the Premises or the Project.

      5.4.2 TERMINATION OF LEASE. Deleted.

      5.4.3 TESTING. At any time prior to the expiration of the Sublease Term,

provided below) appropriate tests of water and soil and to deliver to Tenant the
results of such tests to demonstrate that contamination has occurred as a result
of Tenant's use of the Premises, provided, however, that Landlord shall not
unreasonably interfere with Tenant's business operations. If the results of such
tests demonstrate that contamination has occurred as a result of Tenant's use of
the Premises, Tenant shall reimburse Landlord for the cost of such tests within
ten (10) days following written demand therefor.

      5.4.4 UNDERGROUND TANKS. If underground or other storage tanks storing
Hazardous Materials are located on the Premises or are hereafter placed on the

shall survive the termination of this Sublease. During any period of time
employed by Tenant after the termination of this Sublease to complete the
removal from the Premises of any such Hazardous Materials, the provisions of
Section 2.5 shall apply. To the best of Landlord's knowledge, the Premises and
the Project contain no Hazardous Materials as of the commencement date of this
sublease.

      5.4.6 DEFINITION OF "HAZARDOUS MATERIAL". As used herein, the term
"Hazardous Material" means any hazardous or toxic substance, material or waste

costs and attorney's fees) incurred by reason of (a) any damage to any property
(including but not limited to property of any Landlord Entity) or any injury

Tenant, its agents, servants, employees, invitees or visitors to meet any
standards imposed by any duty with respect to the injury or damage; (b) the
conduct or management of any work or thing whatsoever done by the Tenant in or

termination.

5.6 LANDLORD'S ACCESS. Landlord or its agents may enter the Premises during
normal business hours to show the Premises to potential buyers, investors or
tenants or other parties, or for any other purpose, Landlord reasonably deems
necessary. Landlord shall give Tenant reasonable prior notice of such entry,

                                      -14-
<PAGE>

foregoing, Landlord shall not unreasonably interfere with Tenant's business

                     MAINTENANCE, REPAIRS, AND ALTERATIONS

6.1 EXISTING CONDITIONS. Tenant accepts the Premises in its condition as of the
execution of this Sublease, subject to any other provisions of this Sublease and

for any damage or injury to the person, business (or any loss of income
therefrom), goods, wares, merchandise or other property of Tenant, Tenant's
employees, invitees, customers or any other persons in or about the Premises,
whether such damage or injury is caused by or results from: (a) fire, steam,
electricity, water, gas or rain; (b) the breakage, leakage, obstruction or other
defects of pipes, sprinklers, wires, appliances, plumbing, air conditioning or
lighting fixtures or any other cause; (c) conditions (including the presence of
Hazardous Material) arising in or about the Premises or upon other portions of

other tenant of the Project. Landlord shall not be liable for any such damage or

foregoing damages from any cause arising at any time. The provisions of this
Section 6.2 shall not, however, except Landlord from liability for Landlord's
negligence or willful misconduct, or for Landlord's failure to observe any of
the terms and conditions of this Sublease.

6.3 TENANT'S OBLIGATIONS.

      6.3.1 MAINTENANCE AND REPAIR. Tenant shall keep the Premises (including
all nonstructural, interior and exterior areas, systems and equipment, all
glass, glazing, window moldings, partitions, doors, door hardware, interior
painting, fixtures, and appurtenances thereof (including electrical, lighting,
plumbing, and plumbing fixtures) in good order, condition, and repair during the
Sublease Term. Tenant shall promptly replace any portion of the Premises or
system or equipment in the Premises which cannot be fully repaired, regardless
of whether the

                                      -15-
<PAGE>

benefit of such replacement extends beyond the Sublease Term. Tenant shall also
maintain a preventive maintenance contract providing for the regular inspection
and maintenance of the heating and air conditioning system (including leaks
around ducts, pipes, vents, or other parts of the air conditioning) by a
licensed heating and air conditioning contractor. However, Landlord shall have
the right, upon written notice to Tenant, to undertake the responsibility for
preventive maintenance of the heating and air conditioning system, at Tenant's
expense. It is the intention of the Landlord and Tenant that, at all times
during the Sublease Term, Tenant shall maintain the Premises in an attractive,
first-class fully operative condition. Further, Tenant shall keep the exterior
areas surrounding the Premises free from litter and debris. Tenant waives and
releases its rights under California Civil Code Section 1942.

      6.3.2 TENANT EXPENSE. All of Tenant's obligations under Section 6.3.1
shall be accomplished at Tenant's sole expense. If Tenant refuses or neglects to
properly perform its obligations as required under Section 6.3.1 and to the
reasonable satisfaction of Landlord, Landlord may, on ten (10) days' prior
written notice (except that no notice shall be required in case of emergency)
enter the Premises and perform such obligation on behalf of Tenant without
liability to Tenant for any loss or damage that may accrue to Tenant's
merchandise, fixtures, or other property or to Tenant's business by reason
thereof, and upon completion thereof, Tenant shall pay Landlord's costs for
making such repairs plus fifteen percent (15%) for overhead, upon presentation
of bill therefor, as Additional Rent. Said bill shall include interest at the
Interest Rate on said costs from the date of completion of repairs by Landlord.

6.4 LANDLORD'S OBLIGATIONS. Landlord shall be responsible only for the
maintenance and repair of structural portions of the Premises. As used herein,
structural portions of the Premises shall only refer to the foundation and
slabs, exterior walls, and exterior roof of the Building in which the Premises
are located. If Landlord is required to make repairs to structural portions by
reason of Tenant's conduct or activities, Landlord may add the cost of such
repairs to the Rent which shall thereafter become due. Except for the cost of
repairs subject to reimbursement pursuant to the preceding sentence, Tenant
shall pay its pro rata share, computed in accordance with Subsection 4.2.1
hereof, of all repairs, alterations and improvements made by Landlord to the
structural portions of the Building where the Premises are located. All such
amounts shall be due and payable upon five (5) business days written notice from
Landlord.

      6.5.1 PROHIBITED ACTIONS. Tenant shall not make any alterations, additions
or improvements to the Premises without Landlord's prior written consent, except
for nonstructural alterations which do not exceed Five Thousand Dollars ($5,000)
in cost per alteration, and which are not visible from the outside of the
Premises. In no event may Tenant install any antennas, satellite dishes or other
devices on the roof of the Premises without Landlord's prior written consent,
which consent Landlord may withhold in its sole and absolute discretion,
Landlord may require Tenant to provide demolition and/or lien and completion
bonds in form and amount satisfactory to Landlord. Tenant shall promptly remove
any alterations, additions, or improvements constructed in violation of this
Subsection 6.5.1 upon Landlord's written request. All alterations, additions,
and improvements will be accomplished in good and workmanlike manner, in
conformity with all applicable laws and regulations, and by a contractor
approved by

                                      -16-
<PAGE>

Landlord. Upon completion of any such work, Tenant shall provide Landlord with
"as built" plans (or dimensioned drawings of sufficient detail to reflect the
alterations made by Tenant), copies of all construction contracts, and proof of
payment for all labor and materials. Any additions to, or alterations of, the
Premises, except moveable furniture and trade fixtures, shall become at once a
part of the Premises and belong to Landlord; provided, however, (i) Landlord
shall not be obligated to insure or restore such additions or alterations
pursuant to Subsections 4.4.2 and 7.3, respectively, and (ii) to the extent an
alteration or addition requires Landlord's consent hereunder and Tenant has
failed to obtain such consent, Landlord may require Tenant to remove any such
additions to, or alterations of, the Premises by giving Tenant written notice
thereof prior to the termination of this Sublease in which event Tenant shall
remove the same and repair any damage to the Premises caused by such removal.
Nothing in this Section 6.5.1 shall prevent Tenant from installing trade
fixtures, machinery or other trade equipment in conformance to all applicable
laws and regulations, and the same may be removed upon the termination of this

further that Tenant shall not then be in default under the terms and conditions
of this Sublease.

and material furnished to the Premises.

      6.5.3 FREEDOM FROM LIENS. Tenant shall keep the Premises, all other
property therein and the Project free from any liens arising out of any work
performed, material furnished or obligations incurred by Tenant, and shall
indemnify, hold harmless and defend the Landlord Entities from and against any
liens and encumbrances arising out of any work performed or materials furnished
by or at the direction of Tenant. In the event that Tenant shall not, within
twenty (20) days following the imposition of any such lien, cause such lien to
be released of record by payment or posting of a proper bond, Landlord shall
have, in addition to all other remedies provided herein and by law, the right,
but no obligation, to cause the same to be released by such means as it shall
deem proper, including payment of the claim giving rise to such lien. All such
sums paid by Landlord and all expenses incurred by it in connection therewith,
including attorneys' fees and costs, shall be payable to Landlord by Tenant on
demand with interest at the Interest Rate.

6.5.4 WRITTEN NOTIFICATION REQUIRED. Tenant will notify Landlord in writing ten
(10) days prior to commencing any alterations or additions to allow Landlord
time to file and post notices of nonresponsibility. Landlord reserves the right
to approve any contractor and method of Payment, prior to said contractor making
any improvements to the Premises.

<PAGE>

            (2) No aerial shall be erected on the roof or exterior walls of the

            (5) The plumbing facilities shall not be used for any other purpose
than that for which they are constructed, and no foreign substance of any kind

            (7) The sidewalks, halls, passages, exits, entrances, and stairways
in and about the Project shall not be obstructed by Tenant or used for any
purpose other than for ingress to and egress from the Premises. The halls,

the general public and Landlord shall in all cases retain the right to control
and prevent access thereto by all persons whose presence in the judgment of the
Landlord shall be prejudicial to the safety, character, reputation and interests
of the Project, provided that nothing herein contained shall be constructed to
prevent such access to persons with whom Tenant normally deals in the ordinary
course of Tenant's business unless such persons are engaged in illegal
activities. Tenant and its employees and invitees shall not go upon the roof of
the Building.

            (8) No additional locks or bolts of any kind shall be placed upon
any of the doors or windows by Tenant, nor shall any changes be made in existing

furnished to or otherwise procured by Tenant, and in the event of the loss of
any keys so furnished Tenant shall pay to Landlord the cost thereof.

            (9) Tenant shall not lay linoleum or other similar floor covering so
that the same shall be affixed to the floor of the Premises in any manner except
by a paste, or other material, which may easily be removed with water, the use
of cement or other similar adhesive materials being expressly prohibited. The
method of affixing any such linoleum or other similar floor covering to the
floor, as well as the method of affixing carpets or rugs to the Premises, shall

                                      -18-
<PAGE>

be subject to approval by Landlord. The expense of repairing any damage
resulting from a violation of this rule shall be borne by Tenant.

reasonable rules and regulations applicable to the Premises. Notice of such
rules and regulations and amendments and supplements thereto, if any, shall be
given to the Tenant and Tenant agrees to comply with all such rules and
regulations upon receipt of notice to Tenant from Landlord. Landlord shall not
be liable in any way to Tenant for any damage or inconvenience caused by any
other tenant's noncompliance with these rules and regulations; Landlord shall,
however, use its best commercially reasonable efforts to cause such compliance.

shall surrender the Premises to Landlord, broom-clean and in the same condition
as received except for ordinary wear and tear which Tenant was not otherwise

Article Seven (Damage or Destruction). In addition, and in accordance with
Section 6.5.1, Landlord may require Tenant to remove any alterations, additions
or improvements (where Landlord's consent is required but not obtained, or if at
the time approval is granted Landlord advises Tenant in writing that removal of
the alterations, additions or improvements may be required) prior to the
termination of this Sublease. Any alterations, additions or improvements which
Landlord has not required Tenant to remove shall become Landlord's property and
shall be surrendered to Landlord upon the termination of the Sublease, except
that Tenant may remove any of Tenant's machinery or equipment which can be
removed without material damage to the Premises. Tenant shall repair, at
Tenant's expense, any damage to the Premises caused by the removal of any such
machinery or equipment. In no event, however, shall Tenant remove any of the
following materials or equipment without Landlord's prior written consent: any
power wiring or power panels; lighting or lighting fixtures; wall coverings;

are only partially damaged and if the proceeds received by Landlord from the
insurance policies described

                                      -19-
<PAGE>

in Subsection 4.4.2 are sufficient to pay for the necessary repairs, this
Sublease shall remain in effect and Landlord shall repair the damage as soon as
reasonably possible; provided, however, that if Landlord either (i) fails to
commence such repairs within thirty (30) days, or (ii) fails to complete such
repairs within 270 days, and further provided that such damage materially
interferes with Tenant's business operations, Tenant may elect to terminate this
sublease. Landlord may elect, with Tenant's consent, to repair any damage to
Tenant's equipment, fixtures or improvements installed in the Premises at
Tenant's sole cost and expense. If the insurance proceeds received by Landlord
are not sufficient to pay the entire cost of repair, or if the cause of the
damage is not covered by the insurance policies which Landlord maintains under
Subsection 4.4.2, Landlord may elect either to (a) repair the damage as soon as
reasonably possible, in which case this Sublease shall remain in full force and
effect, or (b) terminate this Sublease as of the date the damage occurred.
Landlord shall notify Tenant within thirty (30) days after receipt of notice of
the occurrence of the damage whether Landlord elects to repair the damage or
terminate this Sublease. Tenant shall pay to Landlord within thirty (30) days
after request therefor by Landlord the "deductible amount" (if any) under
Landlord's insurance policies if the damage was due to an act or omission of
Tenant. If the damage to the Premises occurs during the last twelve (12) months
of the Sublease Term, Landlord or Tenant may elect to terminate this Sublease as
of the date the damage occurred, regardless of the sufficiency of any insurance
proceeds, and Landlord may retain all such proceeds. In such event, Landlord
shall not be obligated to repair or restore the Premises, and the other party
shall have no right to continue this sublease. The notifying party shall notify
the other party of its election within thirty (30) business days after receipt
of notice of the occurrence of the damage.

7.2 TOTAL OR SUBSTANTIAL DESTRUCTION. If the Premises are totally or
substantially destroyed (meaning the cost to repair would exceed twenty-five
percent (25%) of replacement value) by any cause whatsoever, or if the Premises
are in a building which is substantially destroyed (even though the Premises are
not totally or substantially destroyed), or if the Project is substantially
destroyed (even though the Premises are not totally or substantially destroyed),
this Sublease shall, at the election of either Landlord or Tenant, terminate as
of the date the destruction occurred regardless of whether Landlord receives any
insurance proceeds. The notifying party shall notify the other party of such
election within thirty (30) business days after the occurrence of total or
substantial destruction. If the destruction was caused by an act or omission of
Tenant, Tenant shall pay Landlord the difference between the actual cost of
rebuilding and any insurance proceeds received by Landlord.

7.3 LANDLORD'S OBLIGATIONS. Landlord shall promptly commence and diligently
pursue to completion any repairs which it is obligated to effect under Section
7.1. Landlord shall not be required to repair any injury or damage by fire or
other cause to (or to make any restoration or replacement of) any paneling,
decorations, partitions, railings, floor coverings, office fixtures or any other
improvements of property installed in the Premises by Tenant or at the direct or
indirect expense of Tenant which are not part of the original Tenant
improvements paid for by Landlord. Tenant shall be required to restore or
replace same in the event of damage except for damage caused solely by the
Landlord's gross negligence or intentional misconduct that is not covered by the
insurance carried, or required to be carried hereunder, by Tenant. Tenant shall
have no claim against Landlord for any damage suffered by reason of any such

                                      -20-
<PAGE>

damage, destruction, repair or restoration, except to the extent caused by
Landlord's negligence or willful misconduct.

7.4 TEMPORARY REDUCTION OF RENT. If the Premises are destroyed or damaged and
Landlord or Tenant repairs or restores the Premises pursuant to the provisions
of this Article Seven, any Base Rent payable during the period of such damage,
repair and/or restoration shall be reduced in proportion to the rentable space
which is unusable by Tenant in the conduct of its business, but only to the
extent that Landlord has obtained rental income insurance to cover such
abatement of Base Rent. Except for such possible reduction in payments required
from Tenant, Tenant shall not be entitled to any compensation, reduction, or
reimbursement from Landlord as a result of any damage, destruction, repair or
restoration of or to the Premises.

7.5 WAIVER. Tenant waives the provisions of any statute, code or judicial
decision which grants a tenant the right to terminate a lease in the event of
damage or destruction of its premises, including Sections 1932(2) and 1933(4) of
the California Civil Code, due to the fact that Tenant agrees that the
provisions of this Article Seven shall govern the rights and obligations of
Landlord and Tenant in the event of any damage or destruction of the Premises.

                                  ARTICLE VIII
                                  CONDEMNATION

8.1 CONDEMNATION. If all or any portion of the Premises is taken under the power
of eminent domain or sold under the threat of that power (all of which are
called "Condemnation"), this Sublease shall terminate as to the part taken or
sold on the date the condemning authority takes title or possession, whichever
occurs first. If more than twenty percent (20%) of the floor area of the
Premises or more than twenty percent (20%) of the parking spaces available to
Tenant under Section 4.5.3 are taken and Landlord is unable to provide
reasonable substitute parking, either Landlord or Tenant may terminate this
Sublease as of the date the condemning authority takes title or possession,
whichever occurs first, by delivering written notice to the other within ten
(10) days after receipt of written notice of such taking (or in the absence of
such notice, within ten (10) days after the condemning authority takes
possession). If more than twenty percent (20%) of all subleasable space in the
Building in which the Premises are located or more than fifty percent (50%) of
all subleasable space within the Project is taken Landlord may elect to
terminate this Sublease by delivering such notice to Tenant. If neither Landlord
nor Tenant terminates this Sublease, this Sublease shall remain in effect as to
the portion of the Premises not taken, except that the Base Rent shall be
reduced in proportion to the reduction in the floor area of the Premises. Any
Condemnation award or payment shall be distributed in the following order: (a)
first, to any ground lessor, mortgagee or beneficiary under a deed of trust
encumbering the Premises, the amount of its interest in the Premises and Tenant
hereby assigns any other rights which Tenant may have now or in the future to
any other award to Landlord; (b) second, to Tenant, only the amount of any award
specifically designated for loss of or damage to Tenant's trade fixtures or
removable personal property, and Tenant hereby assigns any other rights which
Tenant may have now or in the future to any other award to the Landlord, and (c)
third, to Landlord; the remainder of such award, whether as compensation for
reduction in the value of the subleasehold, the taking of the fee, or otherwise.
If this Sublease is not terminated, Landlord

                                      -21-
<PAGE>

shall repair any damage to the Premises caused by the Condemnation, except that
Landlord shall not be obligated to repair any damage for which Tenant has been
reimbursed by the condemning authority. If the severance damages received by
Landlord are not sufficient to pay for such repair, Landlord shall have the
right to either terminate this Sublease or make such repair at Landlord's
expense.

8.2 WAIVER. Tenant waives the provisions of any statute, code or judicial
decision which grants a tenant the right to terminate a lease in the event of a
taking of its premises, including California Code of Civil Procedure Section
1265.130, due to the fact that Tenant agrees that the provisions of this Article
Eight shall govern the rights and obligations of Landlord and Tenant in the
event of a taking of the Premises.

                                   ARTICLE IX
                            ASSIGNMENT AND SUBLETTING

9.1 LANDLORD'S CONSENT REQUIRED. No portion of the Premises or of Tenant's
interest in this Sublease may be acquired by any other person or entity, whether
by assignment, mortgage, sublease, transfer, operation of law, or act of Tenant,
without Landlord's prior written consent, except as provided in Section 9.2
below. Any attempted transfer without consent shall, at Landlord's option, be
void and shall constitute a noncurable breach of this Sublease. Except as
otherwise provided in Section 9.2, if Tenant is a partnership, limited liability
company or corporation, any cumulative transfer of more than fifty percent (50%)
of the ownership interest in Tenant shall be deemed an assignment of this
Sublease requiring Landlord's consent. If Tenant effects a transfer or requests
the consent of Landlord to any transfer (whether or not such transfer is
consummated), then, upon demand, and as a condition precedent to Landlord's
consideration of the proposed transfer, Tenant agrees to pay Landlord a
non-refundable administrative fee of Two Hundred Dollars ($200.00), plus
Landlord's reasonable attorneys' fees and costs and other costs incurred by
Landlord in reviewing such proposed transfer.

9.2 TENANT AFFILIATE. Tenant may assign this Sublease or sublease the Premises,
without Landlord's consent, to any entity which controls, is controlled by or is
under common control with Tenant, or to any entity resulting from the merger of
or consolidation with Tenant ("Tenant's Affiliate"). In such case, any Tenant's
Affiliate shall assume in writing all of Tenant's obligations under this
Sublease, but Tenant shall remain primarily liable hereunder.

9.3 NO RELEASE OF TENANT. No transfer permitted by this Article Nine, whether
with or without Landlord's consent, shall release Tenant or change Tenant's
primary liability to pay the Rent and to perform all other obligations of Tenant
under this Sublease. Landlord's acceptance of Rent from any other person is not
a waiver of any provision of this Article Nine. Consent to one transfer is not a
consent to any subsequent transfer. If Tenant's transferee defaults under this
Sublease, Landlord may proceed directly against Tenant without pursuing remedies
against the transferee. Landlord may consent to subsequent assignments or
modifications of this Sublease by Tenant's transferee, without notifying Tenant
or obtaining its consent. Such action shall not relieve Tenant's liability under
this Sublease.

                                      -22-
<PAGE>

9.4 LANDLORD'S ELECTION. Tenant's request for consent to any transfer described
in Section 9.1 above shall be accompanied by a written statement setting forth
the details of the proposed transfer, including the name, business and financial
condition of the prospective transferee, financial details of the proposed
transfer (e.g., the term of any rent and security deposit payable under any
assignment or sublease), and any other information Landlord reasonably deems
relevant. Landlord shall have the right (a) to withhold consent in Landlord's
reasonable discretion; (b) to grant consent; or (c) if the transfer is a
sublease of the Premises or an assignment of this Sublease, to terminate this
Sublease as of the effective date of such sublease or assignment, in which case
Landlord may elect to enter into a direct sublease with the proposed assignee or
subtenant. By way of example and without limitation, the parties agree it shall
be reasonable for Landlord to withhold its consent to a proposed transfer if any
of the following situations exist or may exist: (i) the transferee's
contemplated use of the Premises following the proposed transfer is different
than the Permitted Uses set forth in Section 1.6 and is not an appropriate use
for the Project, or in Landlord's opinion is not a use compatible with
contemplated or existing uses within the Project; (ii) in Landlord's reasonable
business judgment, the transferee lacks sufficient business reputation or
experience to operate a successful business of the type and quality permitted
under this Lease; (iii) in Landlord's reasonable business judgment, the present
net worth of the transferee indicates a reasonable likelihood that such
transferee will be unable to perform Tenant's obligations under this Sublease;
or (iv) the proposed transfer would breach any covenant of Landlord respecting
radius, location, use or exclusivity in any other lease, financing agreement, or
other agreement to which Landlord is bound.

9.5 NO MERGER. No merger shall result from Tenant's sublease of the Premises
under this Article Nine. Tenant's surrender of this Sublease or the termination
of this Sublease in any other manner. In any such event, Landlord may terminate
any or all subtenancies or succeed to the interest of Tenant as sublandlord
thereunder.

9.6 EXCESS RENTALS. Tenant agrees to pay to Landlord, as additional rent, all
sums and other consideration payable to and for the benefit of Tenant by the
assignee or sublessee in excess of the rent payable under this Lease for the
same period and portion of the Premises. In calculating excess rent or other
consideration which may be payable to Landlord under this Section 9.6, Tenant
will be entitled to deduct commercially reasonable third party brokerage
commissions and attorneys' fees and other amounts reasonably and actually
expended by Tenant in connection with such assignment or subletting if
acceptable written evidence of such expenditures is provided to Landlord.

                                   ARTICLE X
                               DEFAULTS; REMEDIES

10.1 COVENANTS AND CONDITIONS. Tenant's performance of each of Tenant's
obligations under this Sublease is a condition as well as a covenant. Tenant's
right to continue in possession of the Premises is conditioned upon such
performance. Time is of the essence in the performance of all covenants and
conditions.

                                      -23-
<PAGE>

10.2 DEFAULTS. Tenant shall be in material default under this Sublease:

      10.2.1 VACATION OR ABANDONMENT. If Tenant abandons or vacates the Premises
or if such abandonment or vacation of the Premises results in the cancellation
of any insurance described in Section 4.4; or

      10.2.2 FAILURE TO PAY. If Tenant fails to pay rent or any other charge
required to be paid by Tenant, as and within five (5) business days of the date
when due. The notice required by this Subsection is intended to satisfy any and
all notice requirements imposed by California Code of Civil Procedure Section
1161, et seq. or any other applicable law and is not in addition to any such
requirements; or

      10.2.3 FAILURE TO PERFORM. If Tenant fails to perform any of Tenant's
nonmonetary obligations under this Sublease for a period of thirty (30) days
after written notice from Landlord; provided that if more time is required to
complete such performance, Tenant shall not be in default if Tenant commences
such performance within the thirty (30) day period and thereafter diligently
pursues its completion. However, Landlord shall not be required to give such
notice if Tenant's failure to perform constitutes a non-curable breach of this
Sublease. The notice required by this Subsection is intended to satisfy any and
all notice requirements imposed by California Code of Civil Procedure Section
1161, et seq. or any other applicable law and is not in addition to any such
requirements. Notwithstanding the foregoing, Tenant shall be obligated to
commence performance to cure matters related to the storage or use of hazardous
materials within fifteen days of receipt of notice from Landlord.

      10.2.4 OTHER DEFAULTS. (i) If Tenant makes a general assignment or general
arrangement for the benefit of creditors; (ii) if a petition for adjudication of
bankruptcy or for reorganization or rearrangement is filed by or against Tenant
and is not dismissed within thirty (30) days; (iii) if a trustee or receiver is
appointed to take possession of substantially all of Tenant's assets located at
the Premises or of Tenant's interest in this Sublease and possession is not
restored to Tenant within thirty (30) days; or (iv) if substantially all of
Tenant's assets located at the Premises or of Tenant's interest in this Sublease
is subjected to attachment, execution or other judicial seizure which is not
discharged within thirty (30) days; or (iv) if substantially all of Tenant's
assets located at the Premises or of Tenant's interest in this Sublease is
subjected to attachment, execution or other judicial seizure which is not
discharged within thirty (30) days. If a court of competent jurisdiction
determines that any of the acts described in this Subsection 10.2.4 is not a
default under this Sublease, and a trustee is appointed to take possession (or
if Tenant remains a debtor in possession) and such trustee or Tenant transfers
Tenant's interest hereunder, then Landlord shall receive, as Additional Rent,
the difference between the Rent (or any other consideration) paid in connection
with such assignment or sublease and the Rent payable by Tenant hereunder.

10.3 REMEDIES. On the occurrence of any material default by Tenant, Landlord
may, at any time thereafter, with or without notice or demand and without
limiting Landlord in the exercise of any right or remedy which Landlord may
have:

                                      -24-
<PAGE>

      10.3.1 TERMINATION OF POSSESSION. Terminate Tenant's right to possession
of the Premises by any lawful means, in which case this Sublease shall terminate
and Tenant shall immediately surrender possession of the Premises to Landlord.
In such event Landlord shall have the immediate right to re-enter and remove all
persons and property and such property may be removed and stored in a public
warehouse or elsewhere at the cost of, and for the account of Tenant, all
without service of notice or resort to legal process and without being deemed
guilty of trespass, or becoming liable for any loss or damage which may be
occasioned thereby, and Landlord shall be entitled to recover from Tenant all
damages incurred by Landlord by reason of Tenant's default, including (i) the
worth at the time of the award of all Base Rent, Additional Rent and other
charges which were earned or were payable at the time of the termination; (ii)
the worth at the time of the award of the amount by which the unpaid Base Rent,
Additional Rent and other charges which would have been earned or were payable
after termination until the time of the award exceeds the amount of such Rental
loss 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, Additional
Rent and other charges which would have been payable for the balance of the
Sublease Term after the time of award exceeds the amount of such Rental loss
that Tenant proves could have been reasonably avoided; and (iv) any other amount
necessary to compensate Landlord for all the detriment proximately caused by
Tenant's failure to perform its obligations under this Sublease or which in the
ordinary course of things would be likely to result therefrom, including, but
not limited to, any costs or expenses incurred by Landlord in maintaining or
preserving the Premises after such default, the cost of recovering possession of
the Premises, expenses of reletting, including necessary renovation or
alteration of the Premises, Landlord's reasonable attorneys' fees incurred in
connection therewith, and any real estate commissions or other such fees paid or
payable.

      As used in subparts (i) and (ii) above, the "worth at the time of the
award" is computed by allowing interest on unpaid amounts at the Interest Rate.
As used in subpart (iii) above, the "worth at the time of the award" is computed
by discounting such amount at the discount rate of the Federal Reserve Bank of
San Francisco at the time of the award, plus one percent (1%). If Tenant shall
have abandoned the Premises, Landlord shall have the option of (i) retaking
possession of the Premises and recovering from Tenant the amount specified in
this Subsection 10.3.1, or (ii) proceeding under Subsection 10.3.2.

      10.3.2 MAINTENANCE OF POSSESSION. Maintain Tenant's right to possession,
in which case this Sublease shall continue in effect whether or not Tenant shall
have abandoned the Premises. In such event, Landlord shall be entitled to
enforce all of Landlord's rights and remedies under this Sublease, including the
right to recover the Rent as it becomes due hereunder as permitted by California
Civil Code Section 1951.4 or any successor statute.

      10.3.3 OTHER REMEDIES. Pursue any other remedy now or hereafter available
to Landlord under the laws or judicial decisions of the State of California.

10.4 THE RIGHT TO RELET THE PREMISES. Should Landlord elect to re-enter, as
herein provided, or should it take possession pursuant to legal proceedings or
pursuant to any notice provided for by law, it may either terminate this
Sublease or it may from time to time without terminating this Sublease, make
such alterations and repairs as may be necessary in order

                                      -25-
<PAGE>

to relet the Premises, and relet the Premises or any part thereof for such term
or terms (which may be for a term extending beyond the term of this Sublease)
and at such rental or rentals and upon such other terms and conditions as
Landlord in its sole discretion may deem advisable; upon each such reletting all
rentals received by Landlord from such reletting shall be applied, first, to the
repayment of any indebtedness other than Rent due hereunder from Tenant to
Landlord; second, to the payment of any costs and expenses of such reletting,
including brokerage fees and attorneys' fees and of costs of such alterations
and repairs; third, to the payment of Rent due and unpaid hereunder, and the
residue, if any, shall be held by Landlord and applied in payment of future Rent
as the same may become due and payable hereunder. If such Rentals received from
such reletting during any month are less than that to be paid during that month
by Tenant hereunder, Tenant shall pay any such deficiency to Landlord. Such
deficiency shall be calculated and paid monthly. No such re-entry or taking
possession of the Premises by Landlord shall be construed as an election on its
part to terminate this Sublease unless a written notice of such intention be
given to Tenant or unless the termination thereof be decreed by a court of
competent jurisdiction.

10.5 WAIVER OF RIGHTS OF REDEMPTION. Tenant hereby expressly waives any and all
rights of redemption granted by or under any present or future laws in the event
of Tenant being evicted or dispossessed for any cause, or in the event of
Landlord obtaining possession of the Premises, by reason of the violation by
Tenant of any of the covenants or conditions of this Sublease, or otherwise.

10.6 CUMULATIVE REMEDIES. Landlord's exercise of any right or remedy shall not
prevent it from exercising any other right or remedy.

10.7 RIGHT TO CURE. If Tenant fails, refuses or neglects to perform any
obligation under this Sublease in the time and manner required herein, Landlord
shall have the right, but not the obligation, after ten (10) days prior written
notice to Tenant, to do the same, but at the expense and for the account of
Tenant. The amount of money so expended or obligations so incurred by Landlord,
together with interest thereon at the Interest Rate, shall be repaid to Landlord
as Additional Rent within five (5) days of Tenant's receipt of written notice
thereof. Landlord's performance of such obligations shall not waive any default
by Tenant hereunder.

                                   ARTICLE XI
                            PROTECTION OF CREDITORS

11.1 SUBORDINATION. This Sublease is and shall remain subordinate to the Master
Lease, and to any other ground lease, deed of trust or mortgage encumbering the
Premises, any advances made on the security thereof and any renewals,
modifications, consolidations, replacements or extensions thereof, whenever made
or recorded. However, Landlord shall, within thirty (30) days after the
Commencement Date with respect to any existing encumbrance (including the Master
Lease), and prior to the effective date of any subordination to any future
encumbrance, deliver to Tenant a non-disturbance agreement, in a commercially
reasonable form, in which such ground lessor or the beneficiary or holder of
such encumbrance shall agree to honor all of Tenant's rights and remedies under
this Sublease. If any ground lessor, beneficiary or mortgagee

                                      -26-
<PAGE>

elects to have this Sublease prior to the lien of its ground lease, deed of
trust or mortgage and gives written notice thereof to Tenant, this Sublease
shall be deemed prior to such ground lease, deed of trust or mortgage whether
this Sublease is dated prior or subsequent to the date of said ground lease,
dead of trust or mortgage of the date of recording thereof.

11.2 ATTORNMENT. If Landlord's interest in the Premises is acquired by any
ground lessor, beneficiary under a deed of trust, mortgagee, or purchaser at a
foreclosure sale, Tenant shall attorn, to the transferee of or successor to
Landlord's interest in the Premises and recognize such transferee or successor
as Landlord under this Sublease, Tenant waives the protection of any statute or
rule of law which gives or purports to give Tenant any right to terminate this
Sublease or surrender possession of the Premises upon the transfer of Landlord's
interest.

11.3 SIGNING OF DOCUMENTS. Tenant shall sign and deliver any commercially
reasonable documents necessary or appropriate to evidence any such
non-disturbance, attornment or subordination or agreement to do.

11.4 ESTOPPEL CERTIFICATES.

      11.4.1 LANDLORD'S REQUEST. Upon Landlord's written request, Tenant shall
execute, acknowledge and deliver to Landlord a written statement certifying: (i)
that none of the terms or provisions of this Sublease have been changed (or if
they have been changed, stating how they have been changed); (ii) that this
Sublease has not been canceled or terminated; (iii) the last date of payment of
the Base Rent and other charges and the time period covered by such payment;
(iv) that Landlord is not in default under this Sublease (or, if the Landlord is
claimed to be in default, stating why); and (v) as to such other matters as may
be reasonably requested of Tenant. Tenant shall deliver such statement to
Landlord within ten (10) days after Landlord's request. Any such statement by
Tenant may be given by Landlord to any prospective purchaser or encumbrancer of
the Premises, Such purchaser or encumbrancer may rely conclusively upon such
statement as true and correct.

      11.4.2 FAILURE TO DELIVER. If Tenant does not deliver such statement to
Landlord within such ten (10) day period, Tenant shall be in material default
under this Sublease and, in addition, Landlord, and any prospective purchaser or
encumbrancer, may conclusively presume and rely upon the facts set forth in such
Statement. In such event, Tenant shall be estopped from denying the truth of
such facts.

11.5 TENANT'S FINANCIAL CONDITION. Tenant shall, upon ten (10) days prior
written notice, provide Landlord with a financial statement for the prior year
and, if available, the current year, to the extent such statements are then in
existence, prepared in accordance with generally accepted accounting principles
and, if such is Tenant's normal practice, audited by an independent certified
public accountant.

                                  ARTICLE XII
                                  LEGAL COSTS

12.1 ATTORNEYS' FEES. If either party commences litigation against the other for
the specific performance of this Sublease, for damages for the breach hereof or
otherwise for enforcement of any remedy hereunder, in the event of any such
commencement of litigation, the prevailing party shall be entitled to recover
from the other party such costs and reasonable attorneys' fees as may have been
incurred.

Further, if for any reason Landlord consults legal counsel or otherwise incurs
any costs or expenses as a result of its rightful attempt to enforce the
provisions of this Sublease after Tenant's grace or notice period has expired,
after written notice to Tenant from Landlord that Landlord is seeking the advice
of counsel, even though no litigation is commenced, or if commenced is not
pursued to final judgment, Tenant shall be obligated to pay to Landlord, in
addition to all other amounts for which Tenant is obligated hereunder, all of
Landlord's costs, expenses and reasonable attorneys' fees incurred in connection
with obtaining such advice.

12.2 LANDLORD'S CONSENT. Tenant shall pay Landlord's reasonable attorneys' fees
(not to exceed $500 per occurrence) incurred in connection with Tenant's request
for Landlord's consent under Article Nine (Assignment and Subletting), or in
connection with any other act which Tenant proposes to do and which requires
Landlord's consent.

                            MISCELLANEOUS PROVISIONS

13.1 SUBSTITUTED PREMISES. Deleted.

13.2 LANDLORD'S LIABILITY; CERTAIN DUTIES.

      13.2.1 LANDLORD. As used in this Sublease, the term "Landlord" means only
the current owner or owners of the leasehold estate under the Master Lease at
the time in question. Each Landlord is obligated to perform the obligations of
Landlord under this Sublease only during the time such Landlord owns such
interest or title. Any Landlord who transfers its title or interest is relieved
of all liability with respect to the obligations of Landlord under this Sublease
to be performed on or after the date of transfer. However, each Landlord shall
deliver to its transferee all funds previously paid by Tenant if such funds have
not yet been applied under the terms of this Sublease. Notwithstanding the
foregoing, for purposes of Tenant's indemnification obligations under this
Sublease, the term "Landlord" shall include the current owner(s) of the
leasehold estate under the Master Lease and all prior owner(s) thereof during
the Sublease Term.

      13.2.2 WRITTEN NOTICE. Tenant shall give written notice of any failure by
Landlord to perform any of its obligations under this Sublease to Landlord and
to the District, any ground lessor, mortgagee or beneficiary under any deed of
trust encumbering the Premises whose name and address have been furnished to
Tenant in writing. Landlord shall not be in default under this Sublease unless
Landlord (or the District, or such ground lessor, mortgagee or

                                      -28-
<PAGE>

beneficiary) fails to cure such non-performance within thirty (30) days after
receipt of Tenant's notice. However, if such non-performance reasonably requires
more than thirty (30) days to cure, Landlord shall not be in default if such
cure is commenced within such thirty (30) day period and thereafter diligently
