                                       3

<PAGE>   9

Operating Cost Share Rent and Tax Share Rent, but including any interest for
late payment of any item of Rent.

        (6) Rent as used in this Lease means Base Rent, Operating Cost Share
Rent, Tax Share Rent and Additional Rent. Tenant's agreement to pay Rent is an
independent covenant, with no right of setoff, deduction or counterclaim of any
kind. All Rent shall be paid absolutely net to Landlord.

B. Payment of Operating Cost Share Rent and Tax Share Rent.

        (1) Payment of Estimated Operating Cost Share Rent and Tax Share Rent.
Landlord shall estimate the Operating Costs and Taxes of the Project by April 1
of each fiscal year, or as soon as reasonably possible thereafter. Landlord may
revise these estimates whenever it obtains more accurate information, such as
the final real estate tax assessment or tax rate for the Project.

        Within ten (10) days after receiving the original or revised estimate
from Landlord setting forth an estimate of Operating Costs for a particular
fiscal year, Tenant shall pay Landlord one-twelfth (1/12th) of Tenant's
Proportionate Share of the estimated Operating Costs, multiplied by the number
of months that have elapsed in the applicable fiscal year to the date of such
payment including the current month, minus payments previously made by Tenant
for the months elapsed. On the first day of each month thereafter, Tenant shall
pay Landlord one-twelfth (1/12th) of Tenant's Proportionate Share of this
estimate, until a new estimate becomes applicable.

        Within ten (10) days after receiving the original or revised estimate
from Landlord setting forth an estimate of Taxes for a particular fiscal year,
Tenant shall pay Landlord one-twelfth (1/12th) of Tenant's Proportionate Share
of the estimated Taxes, multiplied by the number of months that have elapsed in
the applicable fiscal year to the date of such payment including the current
month, minus payments previously made by Tenant for the months elapsed. On the
first day of each month thereafter, Tenant shall pay Landlord one-twelfth
(1/12th) of Tenant's Proportionate Share of this estimate, until a new estimate
becomes applicable.

        (2) Correction of Operating Cost Share Rent. Landlord shall deliver to
Tenant a report for the previous fiscal year (the "Operating Cost Report") by
May 15 of each year, or as soon as reasonably possible thereafter, setting forth
(a) the actual Operating Costs incurred, (b) the amount of Operating Cost Share
Rent due from Tenant, and (c) the amount of Operating Cost Share Rent paid by
Tenant. Within twenty (20) days after such delivery, Tenant shall pay to
Landlord the amount due minus the amount paid. If the amount paid exceeds the
amount due, Landlord shall apply the excess to Tenant's payments of Operating
Cost Share Rent next coming due.

                                        4

<PAGE>   10

                (3) Correction of Tax Share Rent. Landlord shall deliver to
        Tenant a report for the previous fiscal year (the "Tax Report") by May
        15 of each year, or as soon as reasonably possible thereafter, setting
        forth (a) the actual Taxes, (b) the amount of Tax Share Rent due from
        Tenant, and (c) the amount of Tax Share Rent paid by Tenant. Within
        twenty (20) days after such delivery, Tenant shall pay to Landlord the
        amount due from Tenant minus the amount paid by Tenant. If the amount
        paid exceeds the amount due, Landlord shall apply any excess as a credit
        against Tenant's payments of Tax Share Rent next coming due.

        C. Definitions.

                (1) Included Operating Costs. "Common Areas" means all areas and
        facilities outside the Building and within the exterior boundary line of
        the Project that are provided and designated by Landlord from time to
        time for the general non-exclusive use of Landlord, Tenant and other
        tenants of the Project and their respective employees, suppliers,
        shippers, customers and invitees, including, without limitation, parking
        areas, loading and unloading areas, trash areas, roadways, sidewalks,
        walkways, parkways, ramps, driveways, landscaped areas and decorative
        walls. "Operating Costs" means any expenses, costs and disbursements of
        any kind other than Taxes, paid or incurred by Landlord in connection
        with the management, maintenance, operation, insurance, repair and other
        related activities in connection with any part of the Project and of the
        personal property, fixtures, machinery, equipment, systems and apparatus
        used in connection therewith, including the cost of providing those
        services required to be furnished by Landlord under this Lease.
        Operating Costs shall also include the costs of any capital improvements
        which are intended to reduce Operating Costs or improve safety, and
        those made to keep the Project in compliance with governmental
        requirements applicable from time to time (collectively, "Included
        Capital Items"); provided, that the costs of any Included Capital Item
        shall be amortized by Landlord, together with an amount equal to
        interest at ten percent (10%) per annum, over the estimated useful life
        of such item and such amortized costs are only included in Operating
        Costs for that portion of the useful life of the Included Capital Item
        which falls within the Term.

                If the Project is not fully occupied during any portion of any
        fiscal year, Landlord may adjust (an "Equitable Adjustment") Operating
        Costs for the Common Areas to equal what would have been incurred by
        Landlord had the Project been fully occupied. If the Building is not
        fully occupied during any portion of any fiscal year, Landlord may make
        an Equitable Adjustment to Operating Costs for the Building to what
        would have been incurred by Landlord had the Building been fully
        occupied. This Equitable Adjustment shall apply only to Operating Costs
        which are variable and therefore increase as occupancy of the Project or
        Building, as applicable, increases. Landlord may incorporate any such
        Equitable Adjustment in its estimates of Operating Costs.

                If Landlord does not furnish any particular service whose cost
        would have constituted an Operating Cost to a tenant other than Tenant
        who has undertaken to

                                        5

<PAGE>   11

perform such service itself, Operating Costs shall be increased by the amount
which Landlord would have incurred if it had furnished the service to such
tenant.

        (2)     Excluded Operating Costs. Operating Costs shall not include:

        (a)     costs of alterations of tenant premises;

        (b)     costs of capital improvements other than Included Capital Items;

        (c)     interest and principal payments on mortgages or any other debt
                costs, or rental payments on any ground lease of the Project;

        (d)     real estate brokers' leasing commissions;

        (e)     legal fees, space planner fees and advertising expenses incurred
                with regard to leasing the Building or portions thereof;

        (f)     any cost or expenditure for which Landlord is reimbursed, by
                insurance proceeds or otherwise, except by Operating Cost Share
                Rent;

        (g)     the cost of any service furnished to any office tenant of the
                Project which Landlord does not make available to Tenant;

        (h)     depreciation (except on any Included Capital Items);

        (i)     franchise or income taxes imposed upon Landlord;

        (j)     costs of correcting defects in construction of the Building (as
                opposed to the cost of normal repair, maintenance and
                replacement expected with the construction materials and
                equipment installed in the Building in light of their
                specifications);

        (k)     legal and auditing fees which are for the benefit of Landlord
                such as collecting delinquent rents, preparing tax returns and
                other financial statements, and audits other than those incurred
                in connection with the preparation of reports required pursuant
                to Section 2B above;

        (1)     the wages of any employee for services not related directly to
                the management, maintenance, operation and repair of the
                Building; and

        (m)     fines, penalties and interest.

        (3) Taxes. "Taxes" means any and all taxes, assessments and charges of
any kind, general or special, ordinary or extraordinary, levied against the
Project, which

                                       6
<PAGE>   12

Landlord shall pay or become obligated to pay in connection with the ownership,
leasing, renting, management, use, occupancy, control or operation of the
Project or of the personal property, fixtures, machinery, equipment, systems and
apparatus used in connection therewith. Taxes shall include real estate taxes,
personal property taxes, sewer rents, water rents, special or general
assessments, transit taxes, ad valorem taxes, and any tax levied on the rents
hereunder or the interest of Landlord under this Lease (the "Rent Tax"). Taxes
shall also include all fees and other costs and expenses paid by Landlord in
reviewing any tax and in seeking a refund or reduction of any Taxes, whether or
not the Landlord is ultimately successful.

        For any year, the amount to be included in Taxes (a) from taxes or
assessments payable in installments, shall be the amount of the installments
(with, any interest) due and payable during such year, and (b) from all other
Taxes, shall at Landlord's election be the amount accrued, assessed, or
otherwise imposed for such year or the amount due and payable in such year. Any
refund or other adjustment to any Taxes by the taxing authority, shall apply
during the year in which the adjustment is made.

        Taxes shall not include any net income (except Rent Tax), capital,
stock, succession, transfer, franchise, gift, estate or inheritance tax, except
to the extent that such tax shall be imposed in lieu of any portion of Taxes.

        (4) Lease Year. "Lease Year" means each consecutive twelve-month period
beginning with the Commencement Date for the Phase A Premises, except that if
the Commencement Date for the Phase A Premises is not the first day of a
calendar month, then the first Lease Year shall be the period from the
Commencement Date for the Phase A Premises through the final day of the twelve
months after the first day of the following month, and each subsequent Lease
Year shall be the twelve months following the prior Lease Year.

        (5) Fiscal Year. "Fiscal Year" means the calendar year, except that the
first fiscal year and the last fiscal year of the Term may be a partial calendar
year.

D. Computation of Base Rent and Rent Adjustments.

        (1) Prorations. If this Lease begins on a day other than the first day
of a month, the Base Rent, Operating Cost Share Rent and Tax Share Rent shall be
prorated for such partial month based on the actual number of days in such
month. If this Lease begins on a day other than the first day, or ends on a day
other than the last day, of the fiscal year, Operating Cost Share Rent and Tax
Share Rent shall be prorated for the applicable fiscal year.

        (2) Default Interest. Any sum due from Tenant to Landlord not paid when
due shall bear interest from the date due until paid at the lesser of eighteen
percent (18%) per annum or the maximum rate permitted by law.

                                       7
<PAGE>   13

                (3) Rent Adjustments. The square footage of the Premises and the
        Building set forth in the Schedule are conclusively deemed to be the
        actual square footage thereof, without regard to any subsequent
        remeasurement of the Premises or the Building. If any Operating Cost
        paid in one fiscal year relates to more than one fiscal year, Landlord
        may proportionately allocate such Operating Cost among the related
        fiscal years.

                (4) Books and Records. Landlord shall maintain books and records
        reflecting the Operating Costs and Taxes in accordance with sound
        accounting and management practices. Tenant and its certified public
        accountant shall have the right to inspect Landlord's records at
        Landlord's office upon at least seventy-two (72) hours' prior notice
        during normal business hours during the ninety (90) days following the
        respective delivery of the Operating Cost Report or the Tax Report. The
        results of any such inspection shall be kept strictly confidential by
        Tenant and its agents, and Tenant and its certified public accountant
        must agree, in their contract for such services, to such confidentiality
        restrictions and shall specifically agree that the results shall not be
        made available to any other tenant of the Building. Unless Tenant sends
        to Landlord any written exception to either such report within said
        ninety (90) day period, such report shall be deemed final and accepted
        by Tenant. Tenant shall pay the amount shown on both reports in the
        manner prescribed in this Lease, whether or not Tenant takes any such
        written exception, without any prejudice to such exception. If Tenant
        makes a timely exception, Landlord shall cause its independent certified
        public accountant to issue a final and conclusive resolution of Tenant's
        exception. Tenant shall pay the cost of such certification unless
        Landlord's original determination of annual Operating Costs or Taxes
        overstated the amounts thereof by more than three percent (3%).

                (5) Miscellaneous. So long as Tenant is in default of any
        obligation under this Lease, Tenant shall not be entitled to any refund
        of any amount from Landlord. If this Lease is terminated for any reason
        prior to the annual determination of Operating Cost Share Rent or Tax
        Share Rent, either party shall pay the full amount due to the other
        within fifteen (15) days after Landlord's notice to Tenant of the amount
        when it is determined. Landlord may commingle any payments made with
        respect to Operating Cost Share Rent or Tax Share Rent, without payment
        of interest.

3. PREPARATION AND CONDITION OF PREMISES; POSSESSION AND SURRENDER OF PREMISES.

        A. Condition of Premises. Except to the extent of the Tenant
Improvements item on the Schedule, Landlord is leasing the Premises to Tenant
absolutely "as is", without any obligation to alter, remodel, improve, repair or
decorate any part of the Premises. Landlord shall cause the Premises to be
completed in accordance with the Tenant Improvement Agreement attached as
Appendix C. Landlord expressly disclaims any warranty or representation, express
or implied, with respect to the Project or any portion thereof, including,
without limitation, any warranty or representation as to fitness, condition, the
existence of any defect, patent or latent, merchantability, quality or
durability; provided that Landlord shall assign to Tenant (or

                                        8

<PAGE>   14

otherwise enforce at Landlord's election in its sole discretion upon Tenant's
written request) any warranties received from any contractors and subcontractors
relating to the Initial Improvements (as defined in Appendix c) and/or the
Premises.

        B. Tenant's Possession. Tenant's taking possession of any portion of the
Premises shall be conclusive evidence that the portion of the Premises as to
which Tenant so took possession was in good order, repair and condition. If
Landlord authorizes Tenant to take possession of any part of the Premises prior
to the Commencement Date for purposes of doing business, all terms of this Lease
shall apply to such pre-Term possession, including Base Rent at the rate set
forth for the First Lease Year in the Schedule prorated for any partial month.

        C. Maintenance. Throughout the Term, Tenant shall maintain the Premises
in good order, repair and condition, loss or damage caused by the elements,
ordinary wear, and fire and other casualty excepted, and at the termination of
this Lease, or Tenant's right to possession, Tenant shall return the Premises to
Landlord in broom-clean, safe, neat and sanitary condition. To the extent Tenant
fails to perform either obligation, Landlord may, but need not, restore the
Premises to such condition and Tenant shall pay the cost thereof.

        4. PROJECT SERVICES.

        Landlord shall furnish services as follows:

        A. Heating and Air Conditioning. During the normal business hours of
8:00 a.m. to 6:00 p.m., Monday through Friday (excluding holidays), and 8:00
a.m. to 12:00 noon on Saturday, Landlord shall furnish heating and air
conditioning to provide a comfortable temperature, in Landlord's judgment, for
normal business operations for buildings comparable to the Building, except to
the extent Tenant installs equipment which adversely affects the temperature
maintained by the air conditioning system. If Tenant installs such equipment,
Landlord may install supplementary air conditioning units in the Premises, and
Tenant shall pay to Landlord upon demand as Additional Rent the cost of
installation, operation and maintenance thereof.

        Landlord shall furnish heating and air conditioning after business hours
if Tenant provides Landlord reasonable prior notice, and pays Landlord all then
current charges for such additional heating or air conditioning.

        B. Elevators. Landlord shall provide passenger elevator service during
normal business hours to Tenant in common with Landlord and all other tenants.
Landlord shall provide limited passenger service at other times, except in case
of an emergency.

        C. Electricity. Landlord shall provide sufficient electricity to operate
normal office lighting and equipment. Tenant shall not install or operate in
the Premises any electrically operated equipment or other machinery, other than
business machines and equipment normally employed for general office use which
do not require high electricity consumption for operation,

                                       9
<PAGE>   15

without obtaining the prior written consent of Landlord. If any or all of
Tenant's equipment requires electricity consumption in excess of that which is
necessary to operate normal office equipment, such consumption (including
consumption for computer or telephone rooms and special HVAC equipment) shall be
submetered by Landlord at Tenant's expense, and Tenant shall reimburse Landlord
as Additional Rent for the cost of its submetered consumption based upon
Landlord's average cost of electricity. Such additional rent shall be in
addition to Tenant's obligations pursuant to Section 2A(2) to pay its
Proportionate Share of Operating Costs.

        D. Water. Landlord shall furnish hot and cold tap water for drinking and
toilet purposes. Tenant shall pay Landlord for water furnished for any other
purpose as Additional Rent at rates fixed by Landlord. Tenant shall not permit
water to be wasted.

        E. Janitorial Service. Landlord shall furnish janitorial services as
generally provided to other tenants in the Project, but not fewer janitorial
services than provided on Appendix F.

        F. Interruption of Services. If any of the Building equipment or
machinery ceases to function properly for any cause Landlord shall use
reasonable diligence to repair the same promptly. Landlord's inability to
furnish, to any extent, the Project services set forth in this Section 4, or any
cessation thereof resulting from any causes, including, without limitation, any
entry for repairs pursuant to this Lease, and any renovation, redecoration or
rehabilitation of any area of the Building shall not render Landlord liable for
damages to either person or property or for interruption or loss to Tenant's
business, nor be construed as an eviction of Tenant, nor work an abatement of
any portion of rent, nor relieve Tenant from fulfillment of any covenant or
agreement hereof. However, in the event that an interruption of the Project
services set forth in this Section 4 is within Landlord's reasonable control and
such interruption causes the Premises to be untenantable for a period of at
least six (6) consecutive business days, monthly Rent shall be abated
proportionately.

        G. Parking. During the Term, Tenant and its employees shall be entitled
to use within the Project's parking area (excluding, however, those areas
thereof designated by Landlord from time to time for the exclusive use of
certain occupants of the Project or for no parking) an aggregate of 4 parking
stalls per 1,000 gross square feet of space in the Premises then occupied by
Tenant. During the initial Term, Tenant shall be entitled to use such parking
stalls at no additional rental, and during the Renewal Term (as defined in
Section 31) Tenant shall pay Landlord the parking rent determined by Landlord as
provided in Section 31 for the use of such parking stalls. Landlord reserves the
right to designate reserved parking stalls for other occupants of the Project
over any part of the Project's parking area; provided that any such reserved
parking stalls shall not be the stalls closest to the Premises.

        H. Tenant's Computer Room. Notwithstanding anything to the contrary set
forth in this Lease (including, without limitation, this Section 4), Landlord
shall have no obligation to provide janitorial service, or any other service for
which Landlord requires access, to Tenant's computer room, nor shall Landlord
have any obligations under this Lease (including, without limitation,
maintenance or repair obligations) with respect to Tenant's computer room unless
and

                                       10
<PAGE>   16

until Tenant provides Landlord with the access thereto required by Landlord to
perform such services or satisfy such obligations. Without limiting the
foregoing, if Landlord determines in its sole discretion that a suspected fire
or flood or other emergency in the Building requires Landlord to gain access to
Tenant's computer room, Landlord may forcibly enter. Landlord shall make a
reasonable effort to contact Tenant to secure access, but Landlord shall have no
obligation to contact Tenant. In such event, Landlord shall have no liability
whatsoever to Tenant, and Tenant shall pay all expenses in repairing any damage
to such computer room.

        5. ALTERATIONS AND REPAIRS.

        A. Landlord's Consent and Conditions.

        Tenant shall not make any improvements or alterations to the Premises
(the "Work") without in each instance submitting plans and specifications for
the Work to Landlord and obtaining Landlord's prior written consent unless (a)
the cost thereof is less than $500, (b) such Work does not impact the base
structural components or systems of the Building, (c) such Work will not impact
any other tenant's premises, and (d) such Work is not visible from outside the
Premises. Tenant shall pay Landlord's standard charge for review of the plans
and all other items submitted by Tenant. Landlord will be deemed to be acting
reasonably in withholding its consent for any Work which (a) impacts the base
structural components or systems of the Building, (b) impacts any other tenant's
premises, or (c) is visible from outside the Premises.

        Tenant shall reimburse Landlord for actual costs incurred for review of
the plans and all other items submitted by Tenant. Tenant shall pay for the cost
of all Work. All Work shall become the property of Landlord upon its
installation, except for Tenant's trade fixtures and for items which Landlord
requires Tenant to remove at Tenant's cost at the termination of the Lease
pursuant to Section 3E.

        The following requirements shall apply to all Work:

                (1) Prior to commencement, Tenant shall furnish to Landlord
        building permits, certificates of insurance satisfactory to Landlord
        (including, without limitation, certificates evidencing the insurance
        Tenant, its contractors and subcontractors are required to maintain
        under Section 8(C)), and, at Landlord's request, security for payment of
        all costs.

                (2) Tenant shall perform all Work so as to maintain peace and
        harmony among other contractors serving the Project and shall avoid
        interference with other work to be performed or services to be rendered
        in the Project.

                (3) The Work shall be performed in a good and workmanlike
        manner, meeting the standard for construction and quality of materials
        in the Building, and shall comply with all insurance requirements and
        all applicable governmental laws, ordinances and regulations
        ("Governmental Requirements").

                                       11
<PAGE>   17

                (4) Tenant shall perform all Work so as to minimize or prevent
        disruption to other tenants, and Tenant shall comply with all reasonable
        requests of Landlord in response to complaints from other tenants.

                (5) Tenant shall perform all Work in compliance with Landlord's
        "Policies, Rules and Procedures for Construction Projects" in effect at
        the time the Work is performed.

                (6) Tenant shall permit Landlord to supervise all Work. If an
        only if Landlord's employees or contractors perform the Work, Landlord
        may charge a supervisory fee not to exceed five percent (5%) of labor,
        material, and all other costs of the Work.

                (7) Upon completion, Tenant shall furnish Landlord with as-built
        plans and specifications, and receipted bills covering all labor and
        materials, and all other close-out documentation required in Landlord's
        "Policies, Rules and Procedures for Construction Projects" and, if
        Tenant or Tenant's employees or contractors perform the Work,
        contractor's affidavits and full and final statutory waivers of liens.

        B. Damage to Systems. If any part of the mechanical, electrical or other
systems in the Premises or Common Areas shall be damaged, Tenant shall promptly
notify Landlord, and Landlord shall repair such damage. Landlord may also at any
reasonable time make any repairs or alterations which Landlord deems necessary
for the safety or protection of the Project, or which Landlord is required to
make by any court or pursuant to any Governmental Requirement. Tenant shall at
its expense make all other repairs necessary to keep the Premises, and Tenant's
fixtures and personal property, in good order, condition and repair; to the
extent Tenant fails to do so, Landlord may make such repairs itself. The cost of
any repairs made by Landlord on account of Tenant's default, or on account of
the mis-use or neglect by Tenant or its invitees, contractors or agents anywhere
in the Project, shall become Additional Rent payable by Tenant on demand.

        C. No Liens. Tenant has no authority to cause or permit any lien or
encumbrance of any kind to affect Landlord's interest in the Project; any such
lien or encumbrance shall attach to Tenant's interest only. If any mechanic's
lien shall be filed or claim of lien made for work or materials furnished to
Tenant, then Tenant shall at its expense within ten (10) days thereafter either
discharge or contest the lien or claim. If Tenant contests the lien or claim,
then Tenant shall (i) within such ten (10) day period, provide Landlord adequate
security for the lien or claim, (ii) contest the lien or claim in good faith by
appropriate proceedings that operate to stay its enforcement, and (iii) pay
promptly any final adverse judgment entered in any such proceeding. If Tenant
does not comply with these requirements, Landlord may discharge the lien or
claim, and the amount paid, as well as attorney's fees and other expenses
incurred by Landlord, shall become Additional Rent payable by Tenant on demand.
Nothing contained in this Lease shall constitute any consent by Landlord to
subject Landlord's estate to liability under any mechanics' or other lien law.
Tenant shall give Landlord adequate opportunity, and

                                       12
<PAGE>   18
Landlord shall have the right at all times, to post such notices of
nonresponsibility as may be allowed under California law.

         D.  Ownership of Improvements. All Work as defined in this Section 5,
partitions, hardware, equipment, machinery and all other improvements and all
fixtures except trade fixtures, constructed in the Premises by either Landlord
or Tenant, (i) shall become Landlord's property upon installation without
compensation to Tenant, unless Landlord consents otherwise in writing, and (ii)
shall at Landlord's option either (a) be surrendered to Landlord with the
Premises at the termination of the Lease or of Tenant's right to possession, or
(b) removed in accordance with Subsection 5E below (unless Landlord at the time
it gives its consent to the performance of such construction expressly waives in
writing the right to require such removal.)

         E.  Removal at Termination. Upon the termination of this Lease or
Tenant's right of possession Tenant shall remove from the Project its trade
fixtures, furniture, moveable equipment and other personal property, any
improvements which Landlord elects shall be removed by Tenant pursuant to
Section 5D, and any improvements to any portion of the Project other than the
Premises. If Tenant does not timely remove such property, then Tenant shall be
conclusively presumed to have, at Landlord's election (i) conveyed such property
to Landlord without compensation or (ii) abandoned such property, and Landlord
may dispose of or store any part thereof in any manner at Tenant's sole cost,
without waiving Landlord's right to claim from Tenant all expenses arising out
of Tenant's failure to remove the property, and without liability to Tenant or
any other person. Landlord shall have no duty to be a bailee of any such
personal property. If Landlord elects abandonment, Tenant shall pay to Landlord,
upon demand, any expenses incurred for disposition. Tenant expressly releases
Landlord of and from any and all claims and liability for damage to or
destruction or loss of property left by Tenant upon the Premises at the
expiration or other termination of this Lease and, to the extent permitted by
then applicable law, Tenant shall protect, indemnify, defend and hold Landlord
harmless from and against any and all claims and liability with respect thereto.

         F.  Landlord's Work. Landlord shall have the right at any time to
change the arrangement and location of all entrances, passageways, doors,
doorways, corridors, stairs, toilets and other public parts of the Project and,
upon giving Tenant not less than ninety (90) days prior notice (except in the
event such change is required by Governmental Requirements or court order, in
which event Landlord shall provide Tenant with reasonable notice under such
circumstances) to change any name, number or designation by which the Premises
or the Project is commonly known.

         6.  USE OF PREMISES. Tenant shall use the Premises only for general
office purposes. Tenant shall not allow any use of the Premises which will
negatively affect the cost of coverage of Landlord's insurance on the Project.
Tenant shall not allow any inflammable or explosive liquids or materials to be
kept on the Premises. Tenant shall not allow any use of the Premises which would
cause the value or utility of any part of the Premises to diminish or would
interfere with any other Tenant or with the operation of the Project by
Landlord. Tenant shall not cause or permit any nuisance or waste upon the
Premises, or allow any offensive noise or

                                       13
<PAGE>   19

odor in or around the Premises or in any way obstruct or interfere with the
rights of other tenants or occupants of the Project.

         Tenant acknowledges that the Americans With Disabilities Act of 1990
(as amended and as supplemented by further laws from time to time, the "ADA")
imposes certain requirements upon the owners, lessees and operators of
commercial facilities and places of public accommodation, including, without
limitation, prohibitions on discrimination against any individual on the basis
of disability. Landlord shall be responsible as of the Commencement Date for the
compliance of the Premises and Common Area with the ADA in effect as of the
Commencement Date, assuming the use of the Premises for general office purposes
and not as a place of public accommodation. Except for Landlord's obligations
pursuant to this paragraph, and notwithstanding any other provision of this
Lease, Tenant agrees, at Tenant's expense, to take all proper and necessary
action to cause the Premises, any repairs, replacements, alterations and
improvements thereto to be maintained, used and occupied in compliance with the
ADA requirements, whether or not those requirements are based upon the Tenant's
use of the Premises and, further, to otherwise assume all responsibility to
ensure the Premises' continued compliance with all provisions of the ADA
throughout the Term. Except for Landlord's obligations pursuant to this
paragraph, Tenant shall, at its expense, make any alterations or modifications,
with or without the Premises, to bring Tenant's use and occupancy of the
Premises into compliance with the ADA. Except for Landlord's obligations
pursuant to this paragraph, Tenant shall pay, as additional rent, its
proportional share of expenses incurred by Landlord in bringing common areas of
the Project into compliance with provisions of the ADA. The Premises shall not
be used as a "place of public accommodation" under the ADA or similar laws,
regulations, statutes and/or ordinances; provided, that if any governmental
authority shall deem the Premises to be a "place of public accommodation" as a
result of Tenant's use, Tenant shall either modify its use to cause such
authority to rescind its designation or be responsible for any alterations,
structural or otherwise, required to be made to the Project or the Premises
under such laws.

         7. GOVERNMENTAL REQUIREMENTS AND PROJECT RULES. Tenant shall comply
with all Governmental Requirements applying to its use of the Premises. Tenant
shall also comply with all reasonable rules established for the Project,
including, without limitation, the parking area, from time to time by Landlord.
The present rules and regulations are contained in Appendix B. Failure by
another tenant to comply with the rules or failure by Landlord to enforce them
shall not relieve Tenant of its obligation to comply with the rules or make
Landlord responsible to Tenant in any way. Landlord shall use reasonable efforts
to apply the rules and regulations uniformly with respect to Tenant and tenants
in the Building under leases containing rules and regulations similar to this
Lease. In the event of alterations and repairs performed by Tenant, Tenant shall
comply with the provisions of Section 5 of this Lease and also Landlord's
"Policies, Rules and Regulations for Construction Projects".

         8. WAIVER OF CLAIMS; INDEMNIFICATION; INSURANCE.

         A. Waiver of Claims. To the extent permitted by law, Tenant waives any
claims it may have against Landlord or its officers, directors, employees or
agents for business

or omission of Landlord.

Landlord and its officers, directors, employees and agents against any claim by
any third party for injury to any person or damage to or loss of any property
occurring in the Project and arising from any act or omission or negligence of
Tenant or any of Tenant's employees or agents. Tenant's obligations under this
section shall survive the termination of this Lease.

        Landlord shall indemnify, defend and hold harmless Tenant and its
officers, directors, employees and agents against any claim by any third party
for injury to any person or damage to or loss of any property occurring in the
Project and arising from any act or omission or negligence of Landlord or any of

respects to insurance required of the Tenant in Section 8C(l). The company or

                (2) Workers' compensation or similar insurance in form and
        amounts required by law, and Employer's Liability with not less than the

        in favor of Landlord and its agents.

        Tenant's contractor's insurance shall be primary and not contributory to
that carried by Tenant, Landlord, their agents or mortgagees. Tenant and

                                       16
<PAGE>   22

subrogation, and the respective "All-Risk" coverage property insurance policies
carried by Landlord and Tenant shall contain enforceable waiver of subrogation
endorsements.

        9. FIRE AND OTHER CASUALTY.

        A. Termination. If a fire or other casualty causes substantial damage to
the Building or the Premises, Landlord shall engage a registered architect to
certify within one (1) month of the casualty to both Landlord and Tenant the
amount of time needed to restore the Building and the Premises to tenantability,
using standard working methods. If the time needed exceeds twelve (12) months
from the beginning of the restoration, or two (2) months therefrom if the
restoration would begin during the last twelve (12) months of the Lease, then in
the case of the Premises, either Landlord or Tenant may terminate this lease,
and in the case of the Building, Landlord may terminate this Lease, by notice to
the other party within ten (10) days after the notifying party's receipt of the
architect's certificate. The termination shall be effective thirty (30) days
from the date of the notice and Rent shall be paid by Tenant to that date, with
an abatement for any portion of the space which has been untenantable after the
casualty.

        B. Restoration. If a casualty causes damage to the Building or the
Premises but this Lease is not terminated for any reason, then subject to the
rights of any mortgagees or ground lessors, Landlord shall obtain the applicable
insurance proceeds and diligently restore the Building and the Premises subject
to current Governmental Requirements. Tenant shall replace its damaged
improvements, personal property and fixtures. Rent shall be abated on a per diem
basis during the restoration for any portion of the Premises which is
untenantable, except to the extent that Tenant's negligence caused the casualty.

        10. EMINENT DOMAIN. If a part of the Project is taken by eminent domain
or deed in lieu thereof which is so substantial that the Premises cannot
reasonably be used by Tenant for the operation of its business, then either
party may terminate this Lease effective as of the date of the taking. If any
substantial portion of the Project is taken without affecting the Premises, then
Landlord may terminate this Lease as of the date of such taking. Rent shall
abate from the date of the taking in proportion to any part of the Premises
taken. The entire award for a taking of any kind shall be paid to Landlord, and
Tenant shall have no right to share in the award. All obligations accrued to the
date of the taking shall be performed by each party.

        11. RIGHTS RESERVED TO LANDLORD.

        Landlord may exercise at any time any of the following rights respecting
the operation of the Project without liability to the Tenant of any kind:

        A. Name. To change the name or street address of the Building or the
suite number(s) of the Premises upon not less than ninety (90) days prior notice

        F. Preparation for Reoccupancy. To decorate, remodel, repair, alter or

entire building in which the Premises are located, to relocate the Tenant, upon
thirty days' prior written notice, from all or part of the Premises (the "Old
Premises") to another area in the Project (the "new premises"), provided that:

                (1) the size of the new premises is at least equal to the size
        of the Old Premises;

                (2) Landlord pays the cost of moving the Tenant and improving
        the new premises to the standard of the Old Premises. Tenant shall
        cooperate with Landlord in all reasonable ways to facilitate the move,
        including supervising the movement of files or fragile equipment,
        designating new locations for furniture, equipment and new telephone and
        electrical outlets, and determining the color of paint in the new
        premises.

unreasonably interfere with Tenant's use of the Premises, except to the extent
such interference is necessary for Landlord's compliance with its obligations
under this Lease or any Governmental Requirements. Landlord may perform any such
repairs or alterations during ordinary business hours, except that Tenant may
require any Work in the Premises to be done after business hours if Tenant pays
Landlord for overtime and any other expenses incurred. Landlord may do or permit
any work on any nearby building, land, street, alley or way.

        L. Landlord's Agents. If Tenant is in default under this Lease,
possession of Tenant's funds or negotiation of Tenant's negotiable instrument by
any of Landlord's agents shall not waive any breach by Tenant or any remedies of
Landlord under this Lease.

        M. Building Services. To install, use and maintain through the Premises,
pipes, conduits, wires and ducts serving the Building, provided that such
installation, use and maintenance does not unreasonably interfere with Tenant's

reasonable in connection with the operation, maintenance or preservation of the
Project.

        12. TENANT'S DEFAULT.

        Any of the following shall constitute a default by Tenant:

        A. Rent Default. Tenant fails to pay any Rent when due or Tenant fails
to deliver any increase in the Security Deposit as required by the provisions of
Section 20;

        B. Assignment/Sublease or Hazardous Substances Default. Tenant defaults
in its obligations under Section 17 Assignment and Sublease or Section 28
Hazardous Substances;

        C. Other Performance Default. Tenant fails to perform any other
obligation to Landlord under this Lease, and, in the case of only the first two
(2) such failures during the Term of this Lease, this failure continues for ten
(10) days after written notice from Landlord (provided, however, that any such
notice shall be in lieu of, and not in addition to, any notice required under
Section 1161 et seq. of the California Code of Civil Procedure), except that if
Tenant begins to cure its failure within the ten (10) day period but cannot

                                       19
<PAGE>   25

reasonably complete its cure within such period, then, so long as Tenant
continues to diligently attempt to cure its failure, the ten (10) day period
shall be extended to sixty (60) days, or such lesser period as is reasonably
necessary to complete the cure;

        D. Credit Default. One of the following credit defaults occurs:

                (1) Tenant commences any proceeding under any law relating to
        bankruptcy, insolvency, reorganization or relief of debts, or seeks
        appointment of a receiver, trustee, custodian or other similar official
        for the Tenant or for any substantial part of its property, or any such
        proceeding is commenced against Tenant and either remains undismissed
        for a period of thirty days or results in the entry of an order for
        relief against Tenant which is not fully stayed within seven days after
        entry;

                (2) Tenant (i) becomes insolvent or bankrupt, (ii) does not
        generally pay its debts as they become due and fails to cure the same
        within thirty (30) days, or (iii) admits in writing its inability to pay
        its debts and fails to cure or rescind the same within thirty (30) days,
        or (iv) makes a general assignment for the benefit of creditors;

                (3) Any third party obtains a levy or attachment under process
        of law against Tenant's leasehold interest.

        E. Vacation or Abandonment Default. Tenant vacates or abandons the
Premises.

        13. LANDLORD REMEDIES.

        A. Termination of Lease or Possession. If Tenant defaults, Landlord may
elect by notice to Tenant either to terminate this Lease or to terminate
Tenant's possession of the Premises without terminating this Lease. In either
case, Tenant shall immediately vacate the Premises and deliver possession to
Landlord, and Landlord may repossess the Premises and may, at Tenant's sole
cost, remove any of Tenant's signs and any of its other property, without
relinquishing its right to receive Rent or any other right against Tenant.
Without limiting the generality of the foregoing, upon the termination of this
Lease or the termination of Tenant's right of possession, it shall be lawful for
the Landlord, without formal demand or notice of any kind, to re-enter the
Premises by summary dispossession proceedings or any other action or proceeding
authorized by law and to remove Tenant and all persons and property therefrom.

        B. Lease Termination Damages. Except as otherwise provided in Section
13C, if Tenant abandons the Premises prior to the end of the term hereof, or if
Tenant's right to possession is terminated by Landlord because of a default by
Tenant under this Lease, this Lease shall terminate. Upon such termination,
Landlord may recover from Tenant the following, as provided in Section 1951.2 of
the California Civil Code: (i) the worth at the time of award of the unpaid Rent
and other charges under this Lease that had been earned at

                                       20
<PAGE>   26
the time of termination; (ii) the worth at the time of award of the amount by
which the unpaid Rent and other charges under this Lease which would have been
earned after termination until the time of award exceeds the amount of such
rental loss that Tenant proves could have been reasonably avoided; (iii) the
worth at the time of award of the amount by which the unpaid Rent and other
charges under this Lease for the balance of the term of this Lease after the
time of award exceeds the amount of such rental loss that Tenant proves could
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 Lease or that in the ordinary course of things would
be likely to result therefrom. As used herein, the following terms are defined:
(a) The "worth at the time of award" 'of the amounts referred to in Sections (i)
and (ii) is computed by allowing interest at the lesser of 15% per annum or the
maximum lawful rate. The "worth at the time of award" of the amount referred to
in Section (iii) is computed by discounting such amount at the discount rate of
the Federal Reserve Bank of San Francisco at the time of award plus 1 %.

        C. Continuation of Lease. Even if Tenant has abandoned the Premises,
this Lease shall continue in effect for so long as Landlord does not terminate
Tenant's right to possession, and Landlord may enforce all its rights and
remedies under this Lease, including the right to recover rent as it becomes
due. This remedy is intended to be the remedy described in California Civil Code
Section 1951.4, and the following provision from such Civil Code Section is
hereby repeated: "The Lessor has the remedy described in California Civil Code
Section 1951.4 (lessor may continue lease in effect after lessee's breach and
abandonment and recover rent as it becomes due, if lessee has right to sublet or
assign, subject only to reasonable limitations)." Any such payments due Landlord
shall be made upon demand therefor from time to time and Tenant agrees that
Landlord may file suit to recover any sums falling due from time to time.
Notwithstanding any such reletting without termination, Landlord may at any time
thereafter elect in writing to terminate this Lease for such previous breach.

        D. Possession Termination Damages. If Landlord terminates Tenant's right
to possession without terminating the Lease and Landlord takes possession of the
Premises itself, Landlord may relet any part of the Premises for such Rent, for
such time, and upon such terms as Landlord in its sole discretion shall
determine, without any obligation to do so prior to renting other vacant areas
in the Building. Any proceeds from reletting the Premises shall first be applied
to the expenses of reletting, including redecoration, repair, alteration,
advertising, brokerage, legal, and other reasonably necessary expenses. If the
reletting proceeds after payment of expenses are insufficient to pay the full
amount of Rent under this Lease, Tenant shall pay such deficiency to Landlord
monthly upon demand as it becomes due. Any excess proceeds shall be retained by
Landlord.

        E. Landlord's Remedies Cumulative. All of Landlord's remedies under this
Lease shall be in addition to all other remedies Landlord may have at law or in
equity. Waiver by Landlord of any breach of any obligation by Tenant shall be
effective only if it is in writing and shall not be deemed a waiver of any other
breach, or any subsequent breach

                                       21
<PAGE>   27

of the same obligation. Landlord's acceptance of payment by Tenant shall not
constitute a waiver of any breach by Tenant, and if the acceptance occurs after
Landlord's notice to Tenant, or termination of the Lease or of Tenant's right to
possession, the acceptance shall not affect such notice or termination.
Acceptance of payment by Landlord after commencement of a legal proceeding or
final judgment shall not affect such proceeding or judgment. Landlord may
advance such monies and take such other actions for Tenant's account as
reasonably may be required to cure or mitigate any default by Tenant. Tenant
shall immediately reimburse Landlord for any such advance, and such sums shall
bear interest at the default interest rate until paid.

        F. WAIVER OF TRIAL BY JURY. EACH PARTY WAIVES TRIAL BY JURY IN THE EVENT
OF ANY LEGAL PROCEEDING BROUGHT BY THE OTHER IN CONNECTION WITH THIS LEASE. EACH
PARTY SHALL BRING ANY ACTION AGAINST THE OTHER IN CONNECTION WITH THIS LEASE IN
A FEDERAL OR STATE COURT LOCATED IN CALIFORNIA, CONSENTS TO THE JURISDICTION OF
SUCH COURTS, AND WAIVES ANY RIGHT TO HAVE ANY PROCEEDING TRANSFERRED FROM SUCH
COURTS ON THE GROUND OF IMPROPER VENUE OR INCONVENIENT FORUM.

        G. Litigation Costs. Tenant shall pay Landlord's reasonable attorneys'
fees and other costs in enforcing this Lease. Notwithstanding the foregoing, if
Landlord or Tenant brings an action to enforce the terms of this Lease or
declare rights hereunder, the prevailing party in such action shall be entitled
to the payment of its attorneys' fees and costs from the other party.

        H. Additional Phases. In addition to all of Landlord's other rights and
remedies under this Lease, in the event of a default by Tenant under this Lease
prior to the Phase B Commencement Date and/or Phase C Commencement Date, then at
Landlord's election in its sole and absolute discretion, Tenant shall not be
entitled to occupy, and this Lease shall not cover, any Phase(s) of the Premises
as to which Tenant has not taken occupancy. Any such election by Landlord shall
be evidenced only in a written notice from Landlord to Tenant and shall be
effective only from and after the date of such notice, and unless and until
Landlord delivers any such notice, this Lease shall continue in full force and
effect as to the entire Premises. No such election by Landlord shall limit or
affect Tenant's obligations or liability (a) with respect to any portion of the
Premises other than the Phase(s) as to which Landlord has elected to terminate
this Lease, as provided in this Section, or (b) with respect to the Phase(s) as
to which Landlord has elected to terminate this Lease and occurring prior to the
effective date of Landlord's election (including, without limitation, any
obligation under Appendix C to pay for any "Initial Improvements" and/or "Change
Orders" (each as defined in Appendix C) constructed or commenced prior to such
effective date). On any such election by Landlord (i) any of Tenant's rights
under Sections 31 and 32 of this Lease shall be concurrently terminated, and
(ii) Landlord shall prepare and deliver to Tenant, and Tenant shall within five
(5) business days execute and deliver to Landlord, an amendment to this Lease
reflecting the Phase(s) as to which this Lease has been terminated and
proportionately

                                       22
<PAGE>   28

adjusting the Base Rent, number of parking spaces allocated to Tenant and
Tenant's Proportionate Share to reflect such termination and amending any other
provision of this Lease as reasonably necessary, as determined by Landlord, to
address such termination.

        14. SURRENDER. Upon termination of this Lease or Tenant's right to
possession, Tenant shall return the Premises to Landlord in good order and
condition, ordinary wear and casualty damage excepted. If Landlord requires
Tenant to remove any alterations, then Tenant shall remove the alterations in a
good and workmanlike manner and restore the Premises to its condition prior to
their installation.

        15. HOLDOVER. If Tenant retains possession of any part of the Premises
after the Term, Tenant shall become a month-to-month tenant for the entire
Premises upon all of the terms of this Lease as might be applicable to such
month-to-month tenancy, except that Tenant shall pay all of Base Rent, Operating
Cost Share Rent and Tax Share Rent at 150% of the rate in effect immediately
prior to such holdover, computed on a monthly basis for each full or partial
month Tenant remains in possession. Tenant shall also pay Landlord all of
Landlord's direct and consequential damages. No acceptance of Rent or other
payments by Landlord under these holdover provisions shall operate as a waiver
of Landlord's right to regain possession or any other of Landlord's remedies.

        16. SUBORDINATION TO GROUND LEASES AND MORTGAGES.

        A. Subordination. This Lease shall be subordinate to any present or
future ground lease or mortgage respecting the Project, and any amendments to
such ground lease or mortgage, at the election of the ground lessor or mortgagee
as the case may be, effected by notice to Tenant in the manner provided in this
Lease. The subordination shall be effective upon such notice, but at the request
of Landlord or ground lessor or mortgagee, Tenant shall within ten (10) days of
the request, execute and deliver to the requesting party any reasonable
documents provided to evidence the subordination.

        B. Termination of Ground Lease or Foreclosure of Mortgage. If any ground
lease is terminated or mortgage foreclosed or deed in lieu of foreclosure given
and the around lessor, mortgagee, or purchaser at a foreclosure sale shall
thereby become the owner of the Project, Tenant shall attorn to such ground
lessor or mortgagee or purchaser without any deduction or setoff by Tenant, and
this Lease shall continue in effect as a direct lease between Tenant and such
ground lessor, mortgagee or purchaser. The ground lessor or mortgagee or
purchaser shall be liable as Landlord only during the time such ground lessor or
mortgagee or purchaser is the owner of the Project. At the request of Landlord,
ground lessor or mortgagee, Tenant shall execute and deliver within ten (10)
days of the request any document furnished by the requesting party to evidence
Tenant's agreement to attorn.

        C. Security Deposit. Any ground lessor or mortgagee shall be responsible
for the return of any security deposit by Tenant only to the extent the
security deposit is received by such ground lessor or Mortgagee.

                                       23
<PAGE>   29

        D. Notice and Right to Cure. The Project is subject to any ground lease
and mortgage identified with name and address of ground lessor or mortgagee in
Appendix D to this Lease (as the same may be amended from time to time by
written notice to Tenant). Tenant agrees to send by registered or certified mail
to any ground lessor or mortgagee identified either in such Appendix or in any
later notice from Landlord to Tenant a copy of any notice of default sent by
Tenant to Landlord. If Landlord fails to cure such-default within the required
time period under this Lease, but ground lessor or mortgagee begins to cure
within ten (10) days after such period and proceeds diligently to complete such
cure, then ground lessor or mortgagee shall have such additional time as is
necessary to complete such cure, including any time necessary to obtain
possession if possession is necessary to cure, and Tenant shall not begin to
enforce its remedies so long as the cure is being diligently pursued.

        E. Definitions. As used in this Section 16, "mortgage" shall include
"trust deed" and "mortgagee" shall include "trustee", "mortgagee" shall include
the mortgagee of any ground lessee, and "ground lessor", "mortgagee", and
"purchaser at a foreclosure sale" shall include, in each case, all of its
successors and assigns, however remote.

        17.    ASSIGNMENT AND SUBLEASE.

        A. In General. Tenant shall not, without the prior consent of Landlord
in each case, (i) make or allow any assignment or transfer, by operation of law
or otherwise, of any part of Tenant's interest in this Lease, (ii) grant or
allow any lien or encumbrance, by operation of law or otherwise, upon any part
of Tenant's interest in this Lease, (iii) sublet any part of the Premises, or
(iv) permit anyone other than Tenant and its employees to occupy any part of the
Premises. Tenant shall remain primarily liable for all of its obligations under
this Lease, notwithstanding any assignment or transfer. No consent granted by
Landlord shall be deemed to be a consent to any subsequent assignment or
transfer, lien or encumbrance, sublease or occupancy. Tenant shall pay all of
Landlord's attorneys' fees and other expenses incurred in connection with any
consent requested by Tenant or in reviewing any proposed assignment or
subletting. Any assignment or transfer, grant of lien or encumbrance, or
sublease or occupancy without Landlord's prior written consent shall be void. If
Tenant shall assign this Lease or sublet the Premises in its entirety any rights
of Tenant to renew this Lease, extend the Term to lease additional space in the
Project shall be extinguished thereby and will not be transferred to the
assignee or subtenant, all such rights being personal to the Tenant named
herein.

        B. Landlord's Consent. Landlord will not unreasonably withhold its
consent to any proposed assignment or subletting. It shall be reasonable for
Landlord to withhold its consent to any assignment or sublease if (i) Tenant is
in default under this Lease, (ii) the proposed assignee or sublessee is a tenant
in the Project or an affiliate of such a tenant or a party that Landlord has
identified as a prospective tenant in the Project, (iii) the financial
responsibility, nature of business, and character of the proposed assignee or
subtenant are not all reasonably satisfactory to Landlord, (iv) in the
reasonable judgment of Landlord the

                                       24
<PAGE>   30

purpose for which the assignee or subtenant intends to use the Premises (or a
portion thereof) is not in keeping with Landlord's standards for the Building or
are in violation of the terms of this Lease or any other leases in the Project,
(v) the proposed assignee or subtenant is a government entity, or (vi) the
proposed assignment is for less than the entire Premises or for less than the
remaining Term of the Lease. The foregoing shall not exclude any other
reasonable basis for Landlord to withhold its consent.

        C. Procedure. Tenant shall notify Landlord of any proposed assignment or
sublease at least thirty (30) days prior to its proposed effective date. The
notice shall include the name and address of the proposed assignee or subtenant,
its corporate affiliates in the case of a corporation and its partners in a case
of a partnership, an execution copy of the proposed assignment or sublease, and
sufficient information to permit Landlord to determine the financial
responsibility and character of the proposed assignee or subtenant. As a
condition to any effective assignment of this Lease, the assignee shall execute
and deliver in form satisfactory to Landlord at least fifteen (15) days prior to
the effective date of the assignment, an assumption of all of the obligations of
Tenant under this Lease. As a condition to any effective sublease, subtenant
shall execute and deliver in form satisfactory to Landlord at least fifteen (15)
days prior to the effective date of the sublease, an agreement to comply with
all of Tenant's obligations under this Lease, and at Landlord's option, an
agreement (except for the economic obligations which subtenant will undertake
directly to Tenant) to attorn to Landlord under the terms of the sublease in the
event this Lease terminates before the sublease expires.

        D. Change of Management or Ownership. Any transfer of the direct or
indirect power to affect the management or policies of Tenant or direct or
indirect change in 25% or more in the aggregate of the ownership interest in
Tenant shall constitute an assignment of this Lease.

        E. Excess Payments. If Tenant shall assign this Lease or sublet any part
of the Premises for consideration in excess of the pro-rata portion of Rent
applicable to the space subject to the assignment or sublet, then Tenant shall
pay to Landlord as Additional Rent 50% of any such excess immediately upon
receipt.

        F. Recapture. Except in the event of assignment or subletting to an
affiliate (as hereinafter defined) of Tenant, Landlord may, by giving written
notice to Tenant within thirty (30) days after receipt of Tenant's notice of
assignment or subletting, terminate this Lease with respect to the space
described in Tenant's notice, as of the effective date of the proposed
assignment or sublease and all obligations under this Lease as to such space
shall expire except as to any obligations that expressly survive any termination
of this Lease. Tenant's notice of assignment or subletting for the purposes of
this Section 17(F) may be given when Tenant notifies Landlord of Tenant's good
faith intent to assign this Lease or sublet a specific portion of Premises and
may be given before Tenant has identified a specific proposed assignee or
sublessee.

                                       25
<PAGE>   31

        18. CONVEYANCE BY LANDLORD. If Landlord shall at any time transfer its
interest in the Project or this Lease, Landlord shall be released of any
obligations occurring after such transfer, except the obligation to return to
Tenant any security deposit not delivered to its transferee, and Tenant shall
look solely to Landlord's successors for performance of such obligations.
Subject to the provisions of Section 16, this Lease shall not be affected by any
such transfer.

        19. ESTOPPEL CERTIFICATE. Each party shall, within ten (10) days of
receiving a request from the other party, execute, acknowledge in recordable
form, and deliver to the other party or its designee a certificate stating,
subject to a specific statement of any applicable exceptions, that the Lease as
amended to date is in full force and effect, that the Tenant is paying Rent and
other charges on a current basis, and that to the best of the knowledge of the
certifying party, the other party has committed no uncured defaults and has no
offsets or claims. The certifying party may also be required to state the date
of commencement of payment of Rent, the Commencement Date, the Termination Date,
the Base Rent, the current Operating Cost Share Rent and Tax Share Rent
estimates, the status of any improvements required to be completed by Landlord,
the amount of any security deposit, and such other matters as may be reasonable
requested. Failure to deliver such statement within the time required shall be
conclusive evidence against the non-certifying party that this Lease, with any
amendments identified by the requesting party, is in full force and effect, that
there are no uncured defaults by the requesting party, that not more than one
month's Rent has been paid in advance, that the non-certifying party has not
paid any security deposit, and that the non-certifying, party has no claims or
offsets against the requesting party.

        20. SECURITY DEPOSIT. Tenant shall deposit with Landlord on the date of
this Lease, security for the performance of all of its obligations in the amount
set forth on the Schedule (the "Initial Security Deposit"). The Initial Security
Deposit has been calculated by multiplying the number of gross rentable square
feet in the Phase A Premises times four times the Security Deposit Multiplier.
As used herein, "Security Deposit Multiplier" means from time to time the
aggregate of the monthly Base Rent per gross rentable square foot then in effect
under this Lease plus the month Operating Cost Share Rent and Tax Share Rent due
under this Lease on a gross rentable square foot basis; with such Security
Deposit Multiplier changing as and when such amounts change. For the purposes of
determining the Initial Security Deposit, the Security Deposit Multiplier has
been estimated to be $1.90 ($1.35 plus an estimated $0.55 for such Operating
Cost Share Rent and Tax Share Rent). Tenant acknowledges and agrees that the
foregoing estimate of Operating Cost Share Rent and Tax Share Rent has been made
solely for the parties' ease in calculating the Initial Security Deposit and
such estimate shall not limit or affect any of the provisions of this Lease,
including, without limitation, the provisions of this Lease regarding the
payment of Operating Cost Share Rent and Tax Share Rent and the provisions of
this Section 20.

        The Security Deposit shall be increased upon the Phase B Commencement
Date, the Phase C Commencement Date, and any increase from time to time in the
Security Deposit

                                       26
<PAGE>   32

Multiplier, and concurrently therewith Tenant shall deliver to Landlord, in
immediately available funds, the amount necessary to increase the Security
Deposit then held by Landlord to an amount equal to the number of gross rentable
square feet then in the Premises multiplied by four multiplied by the then
applicable Security Deposit Multiplier, as the same may be reduced as provided
in the next paragraph.

        So long as no default by Tenant and no event which with the giving of
notice or the passage of time would constitute a default by Tenant, exists at
the time of the applicable reduction, the amount of the Security Deposit then
held by Landlord may be reduced as follows: (a) at the end of the first Lease
Year, the Security Deposit may be reduced by an amount equal to the gross
rentable square feet then in the Premises multiplied by the Security Deposit
Multiplier; provided that the reduction otherwise applicable at the end of the
first Lease Year may instead occur at the end of Tenant's 1999 fiscal year (and
there shall be no reduction under this clause (a) at the end of the first Lease
Year) if Tenant's audited financial statements show Tenant's revenues for the
1999 fiscal year to be not less than $25,000,000, Tenant's net income for the
1999 fiscal year to be not less than $1,000,000 and Tenant's shareholder's
equity at the end of the 1999 fiscal year to be not less than $1,000,000; (b) at
the end of the second Lease Year, the Security Deposit may be reduced by an
amount equal to the gross rentable square feet then in the Premises multiplied
by the Security Deposit Multiplier; provided that the reduction otherwise
applicable at the end of the second Lease Year may instead occur at the end of
Tenant's 2000 fiscal year (and there shall be no reduction under this clause (b)
at the end of the second Lease Year) if Tenant's audited financial statements
show Tenant's revenues for the 2000 fiscal year to be not less than $30,000,000,
Tenant's net income for the 2000 fiscal year to be not less than $1,200,000 and
Tenant's shareholder's equity at the end of the 2000 fiscal year to be not less
than $1,200,000; (c) at the end of the third Lease Year, the Security Deposit
may be reduced by an amount equal to the gross rentable square feet then in the
Premises multiplied by the Security Deposit Multiplier; provided that the
reduction otherwise applicable at the end of the third Lease Year may instead
occur at the end of Tenant's 2001 fiscal year (and there shall be no reduction
under this clause (c) at the end of the third Lease Year) if Tenant's audited
financial statements show Tenant's revenues for the 2001 fiscal year to be not
less than $36,000,000, Tenant's net income for the 2001 fiscal year to be not
less than $1,440,000, and Tenant's shareholder's equity at the end of the 2001
fiscal year to be not less than $1,440,000; and (d) at any time that Tenant's
stock is publicly traded on a nationally recognized stock exchange, the Security
Deposit may be reduced to an amount equal to the gross rentable square feet then
in the Premises multiplied by the Security Deposit Multiplier (and if at any
time thereafter, Tenant's stock ceases to be so publicly traded, the Security
Deposit shall be increased by Tenant to the amount that would otherwise be
required by this Section 20). Any reduction in the Security Deposit shall be
held by Landlord and applied to the next payment(s) of Rent due under this
Lease. Notwithstanding anything to the contrary set forth herein, the Security
Deposit held by Landlord shall not be reduced below an amount equal to the gross
rentable square feet then in the Premises multiplied by the Security Deposit
Multiplier and if any reduction contemplated by this paragraph would reduce the
Security Deposit below such amount, such reduction shall be of no force and
effect.  If

                                       27
<PAGE>   33
Tenant desires a reduction in the Security Deposit based on Tenant's revenues,
shareholder's equity and net income as provided herein, before such reduction
in the Security Deposit Tenant shall deliver to Landlord Tenant's financial
statements for the applicable fiscal year, prepared in accordance with
generally accepted accounting principles consistently applied, and audited by
an independent certified public accountant. The provisions of this paragraph
allowing for the reduction of the Security Deposit are applicable only if and
when Zland, Inc. is the Tenant hereunder (and if at any time Zland, Inc. is not
the Tenant hereunder there shall be no such reduction of the Security Deposit).

        If Tenant defaults under this Lease, Landlord may use any part of the
Security Deposit to make any defaulted payment, to pay for Landlord's cure of
any defaulted obligation, or to compensate Landlord for any loss or damage
resulting from any default. To the extent any portion of the deposit is used,
Tenant shall within five (5) days after demand from Landlord restore the
deposit to its full amount. Landlord may keep the Security Deposit in its
general funds and shall not be required to pay interest to Tenant on the
deposit amount. If Tenant shall perform all of its obligations under this Lease
and return the Premises to Landlord at the end of the Term, Landlord shall
return all of the remaining Security Deposit to Tenant not later than thirty
(30) days after the delivery of possession of the Premises to Landlord. The
Security Deposit shall not serve as an advance payment of Rent or a measure of
Landlord's damages for any default under this Lease. If the Basic Rent shall,
from time to time, increase during the term of this Lease (as extended from
time to time), Tenant shall, upon Landlord's election, deposit with Landlord
additional money as a Security Deposit so that the total amount of Security
Deposit held by Landlord shall at all times bear the same proportion to the
then current Basic Rent as the initial Security Deposit bears to the initial
Basic Rent set forth in the Schedule.

        Tenant waives the provisions of California Civil Code Section 1950.7,
and all other provisions of law now in force or that become in force after the
date of execution of this Lease, that provide that Landlord may claim from a
security deposit only those sums reasonably necessary to remedy any defaults in
the payment of Rent, to repair damage caused by Tenant, or to clean the
Premises. Landlord and Tenant agree that Landlord may, in addition, claim those
sums reasonably necessary to compensate Landlord for any other foreseeable or
unforseeable loss or damage caused by the act or omission of Tenant or Tenant's
officers, agents, employees, independent contractors, or invitees.

        If Landlord transfers its interest in the Project or this Lease,
Landlord shall either (a) transfer the portion of the Security Deposit then
held by Landlord to its transferee or (b) return to Tenant the portion of the
Security Deposit then held by Landlord and remaining after the deductions
permitted herein. Upon such transfer to such transferee or the return of the
Security Deposit to Tenant, Landlord shall have no further obligation with
respect to the Security Deposit, and Tenant's right to the return of the
Security Deposit shall apply solely against Landlord's transferee.

                                       28

<PAGE>   34

        21. FORCE MAJEURE.  Landlord shall not be in default under this Lease
to the extent Landlord is unable to perform any of its obligations on account
of any strike or labor problem, energy shortage, governmental pre-emption or
prescription, flood, earthquake, national emergency, or any other cause of any
kind beyond the reasonable control of Landlord ("Force Majeure"). Force Majeure
shall include, without limitation, any failure of, or delay by, the
appropriate governmental authorities to issue any permits or grant any
approvals. Without limiting the foregoing, any failure of any of the applicable
governmental authorities to issue all necessary building permits for the
Initial Improvements within thirty (30) days after the initial application shall
constitute Force Majeure. In the event of Force Majeure resulting from strike
or labor problem, Landlord shall use reasonable efforts to find alternate
providers at a comparable cost, subject to any Governmental Requirements and/or
labor agreements.

        22. TENANT'S PERSONAL PROPERTY AND FIXTURES. Tenant hereby grants to
Landlord all of its personal property and fixtures now or hereafter located
within the Premises as security for performance of all of Tenant's obligations
under this Lease. Tenant may replace such personal property and fixtures with
items of equal or better quality, but shall not otherwise remove them from the
Premises without the consent of Landlord until all of the obligations of Tenant
under this Lease have been performed. This Lease constitutes a security
agreement creating a security interest in such property in favor of Landlord,
subject only to the liens of existing creditors, and Landlord may at any time
file this Lease as a financing statement under the Uniform Commercial Code of
the state in which the Project is located. Landlord shall only exercise its
rights with respect to the security interest granted by this Section 22 if
Tenant's personal property or fixtures remain in the Premises or Project after
the expiration or earlier termination of this Lease.

        23. NOTICES. All notices, consents, approvals and similar
communications to be given by one party to the other under this Lease
(including, without limitation, any notice required by law to be given by
Landlord to Tenant as a condition to the filing of an action alleging an
unlawful detainer of the Premises and any three (3) day notice under Section
1161(2) or (3) of the California Code of Civil Procedure), shall be given in

        X. Late Charge and Interest on Late Payments. Without limiting the
provisions of Section 12A, if Tenant fails to pay any installment of Rent or
other charge to be paid by Tenant pursuant to this Lease within five (5)
business days after the same becomes due and payable, then Tenant shall pay a
late charge equal to the greater of five percent (5%) of the amount of such
payment or $250. In addition, interest shall be paid by Tenant to Landlord on
any late payments of Rent from the date due until paid at the rate provided in
Section 2D (2). Such late charge and interest shall constitute additional Rent
due and payable by Tenant to Landlord upon the date of payment of the delinquent
payment referenced above.

        27. UNRELATED BUSINESS INCOME. If Landlord is advised by its counsel at
any time that any part of the payments by Tenant to Landlord under this Lease
may be characterized as unrelated business income under the United States
Internal Revenue Code and its regulations, then Tenant shall enter into any
amendment proposed by Landlord to avoid such income, so long as the amendment
does not require Tenant to make more payments or accept fewer services from
Landlord, than this Lease provides.

        28. HAZARDOUS SUBSTANCES.

        A. Tenant shall not cause or permit any Hazardous Substances to be
brought upon, produced, stored, used, discharged or disposed of in or near the
Project unless Landlord has consented to such storage or use in its sole
discretion. If any lender or governmental agency shall require testing for
Hazardous Substances in the Premises, Tenant shall pay for such testing.

        B. "Hazardous Substances" means (a) any chemical, compound, material,
mixture or substance that is now or hereafter defined or listed in, or otherwise
classified pursuant to, any Environmental Laws as a "hazardous substance",
"hazardous material", "hazardous waste", "extremely hazardous waste", "acutely
hazardous waste", "radioactive waste", "infectious waste", "biohazardous waste",
"toxic substance", "pollutant", "toxic pollutant", contaminant" as well as any
formulation not mentioned herein intended to define, list, or classify
substances by reason of deleterious properties such as ignitability,
corrosivity, reactivity, carcinogenicity, toxicity, reproductive toxicity, "EP
toxicity", or "TCLP toxicity"; (b) petroleum, natural gas, natural gas liquids,
liquefied natural gas, synthetic gas usable for fuel (or mixtures of natural gas
and such synthetic gas) and ash produced by a resource recovery facility
utilizing a municipal solid waste stream, and drilling fluids, produced waters
and other wastes associated with the exploration, development or production of
crude oil, natural gas, or geothermal resources; (c) "hazardous substance" as
defined in Section 25281(f) of the California Health and Safety Code; (d)
"waste" as defined in Section 13050(d) of the California Water Code; (e)
asbestos in any form; (f) urea formaldehyde foam insulation; (g) polychlorinated
biphenyls (PCBs); (h) radon; and (i) any other chemical, material, or substance
exposure to which is limited or regulated by any Governmental Agency because of
its quantity, concentration, or physical or chemical characteristics, or which
poses a significant present or potential hazard to human health or safety or to
the environment if released into the workplace or the environment. "Hazardous
Substances"

                                       33
<PAGE>   39

shall not include ordinary office supplies and repair, maintenance and cleaning
supplies maintained in reasonable and necessary quantities and used in
accordance with all Environmental Laws. "Environmental Laws" means any and all
present and future federal, state and local laws, ordinances, regulations,
policies and any other requirements of any Governmental Agency relating to
health, safety, the environment or to any Hazardous Substances, including
without limitation, the Comprehensive Environmental Response, Compensation, and
Liability Act of 1980 (CERCLA), the Resource Conservation Recovery Act (RCRA),
the Hazardous Materials Transportation Act, the Toxic Substance Control Act, the
Endangered Species Act, the Clean Water Act, the Occupational Safety and Health
Act, the California Environmental Quality Act and the applicable provisions of
the California Health and Safety Code, California Labor Code and the California
Water Code, each as hereafter amended from time to time, and the present and
future rules, regulations and guidance documents promulgated under any of the
foregoing.

        C. Without limiting Tenant's liability and obligations under Sections
28(D), (E), (F) and (G), the foregoing covenant set forth in Section 28(A) shall
not extend to insignificant amounts of substances typically found or used in
general office applications so long as (i) such substances are maintained only
in such quantities as are reasonably necessary for Tenant's operations in the
Premises, (ii) such substances are used strictly in accordance with the
manufacturers' instructions therefor and all applicable Environmental Laws,
(iii) such substances are not disposed of in or about the Project in a manner
which would constitute a release or discharge thereof, and (iv) all such
substances are removed from the Project by Tenant upon the expiration or earlier
termination of this Lease. Tenant shall, within thirty (30) days after demand
therefor, provide to Landlord a written list identifying any Hazardous Materials
then maintained by Tenant in the Building, the use of each such Hazardous
Material so maintained by Tenant together with written certification by Tenant
stating, in substance, that neither Tenant nor any person for whom Tenant is
responsible has released or discharged any Hazardous Materials in or about the
Project.

        D. In order to obtain Landlord's consent under this Section 28 with
respect to any Hazardous Material other than as specified in Section 28(C)
above, Tenant shall first submit a detailed hazardous material management plan
describing all relevant aspects of the same to Landlord for approval, which
approval may be withheld by Landlord in its sole and absolute discretion. No
approval by Landlord shall relieve Tenant of any obligation of Tenant pursuant
to this Section 28, including all removal, clean-up and indemnification
obligations. Tenant shall, within five (5) days after receipt thereof, furnish
to Landlord copies of all notices or other communications received by Tenant
with respect to any actual or alleged release or discharge of any Hazardous
Material in or about the Premises or the Project and shall, whether or not
Tenant receives any such notice or communication, notify Landlord in writing of
any discharge or release of Hazardous Material by Tenant or anyone for whom
Tenant is responsible in or about the Premises or the Project. In the event
Tenant is required to maintain any hazardous materials license or permit in
connection with any use conducted by Tenant or any equipment operated by Tenant
in the Premises, copies of each such license or permit, each renewal thereof,
and any communication relating to suspension, renewal or

                                       34
<PAGE>   40

revocation thereof shall be furnished to Landlord within five (5) days after
receipt thereof by Tenant. Compliance by Tenant with this Section 28(C) shall
not relieve Tenant of any other obligation of Tenant pursuant to this Section
28.

        E. Upon any violation of the foregoing covenants and in all events upon
any expiration of the Term, Tenant shall be obligated, at Tenant's sole cost, to
clean up and remove from the Project all Hazardous Materials introduced into the
Project by Tenant or any third party for whom Tenant is responsible. Such
clean-up and removal shall include all testing and investigation required by any
governmental authorities having jurisdiction and preparation and implementation
of any remedial action plan required by any governmental authorities having
jurisdiction. All such clean-up and removal activities of Tenant shall, in each
instance, be conducted to the satisfaction of Landlord and all governmental
authorities having jurisdiction. Landlord's right of entry pursuant to Section
11 of this Lease shall include the right (but not the obligation) to enter and
inspect the Premises for violations of Tenant's covenant herein and to supervise
any of Tenant's clean-up and removal activities.

        F. To the extent permitted by then applicable law, Tenant shall protect,
indemnify, defend and hold harmless Landlord, the partners of any entity
constituting Landlord and Landlord's partners, officers, employees, agents,
lenders and attorneys from and against any and all claims, liabilities, losses,
actions, costs and expenses (including attorneys' fees and costs of defense)
incurred by such indemnified persons, or any of them, as the result of (i) the
introduction into the Project by Tenant, its employees, agents, licensees,
invitees, contractors or any other person or entity for whom Tenant is
responsible of any Hazardous Material, (ii) the usage by Tenant or anyone for
whom Tenant is responsible of Hazardous Materials in or about the Project, (iii)
the discharge or release in or about the Project by Tenant or anyone for whom
Tenant is responsible of any Hazardous Material, (iv) any injury to or death of
persons or damage to or destruction of property resulting from the use by Tenant
or anyone for whom Tenant is responsible of Hazardous Materials in or about the
Project, and (v) any failure of Tenant or anyone for whom Tenant is responsible
to observe the foregoing covenants. Payment shall not be a condition precedent
to enforcement of the foregoing indemnification provision.

        G. Upon any violation of any of the foregoing covenants, Landlord shall
be entitled to exercise all remedies available to a landlord against the
defaulting tenant, including but not limited to those set forth in Section 13 of
this Lease. Without limiting the generality of the foregoing, Tenant expressly
agrees that upon any such violation Landlord may, at its option (i) immediately
terminate this Lease, or (ii) continue this Lease in effect until compliance by
Tenant with its clean-up and removal covenant (notwithstanding the expiration of
the term of this Lease). No action by Landlord hereunder shall impair the
obligations of Tenant pursuant to this Section 28.

        29. EXCULPATION. Landlord shall have no personal liability under this
Lease; its liability shall be limited to its interest in the Project, and shall
not extend to any other property or assets of the Landlord. In no event shall
any officer, director, employee, agent,

                                       35
<PAGE>   41

shareholder, partner, member or beneficiary of Landlord be personally liable for
any of Landlord's obligations hereunder. Without limiting Landlord's recourse
against Tenant, in no event shall any officer, director, employee, agent or
shareholder of Tenant be personally liable for any of Tenant's obligations
hereunder.

        30. SIGNAGE. Subject to Landlord's reasonable prior written approval of
the location, design, size, color, material, composition and plans and
specifications therefor, Tenant may, at its sole cost and expense, construct and
maintain a top sign on the Building (the "Building Sign") to the extent
permitted by all Governmental Requirements. If Landlord grants its approval,
Tenant shall erect the Building Sign in accordance with the approved plans and
specifications, in a good and workmanlike manner, in accordance with all
applicable Governmental Requirements, now in force or hereafter enacted, of any
governmental entity or agency having jurisdiction over the Premises, and after
Tenant has received all requisite approvals thereunder (all of which being
referred to herein collectively as the "Sign Requirements"), and in a manner so
as not to unreasonably interfere with the construction or use of the Building,
Common Areas or other portions of the Project while such construction is taking
place, and thereafter, Tenant shall maintain the Building Sign in a good, clean
and safe condition and in accordance with the Sign Requirements, including all
repairs and replacements thereto. Upon the expiration or earlier termination of
the Lease Tenant shall, at its sole cost and expense, remove the Building Sign
and repair all damage caused thereby and restore the applicable portion of the
Building to its condition prior to the installation and removal of the Building
Sign.

        31. EXTENSION OPTION. Subject to Subsections B and C below, Tenant may
at its option extend the Term of this Lease for the entire Premises for one
period of five (5) years (the "Renewal Term") upon the same terms contained in
this Lease, excluding the provisions of Section 32 and Appendix C of this Lease
and except for the amount of Base Rent payable during the Renewal Term. Tenant
shall have no additional extension option.

        A. The Base Rent during the Renewal Term shall be the then prevailing
market rate for a comparable term commencing on the first day of the Renewal
Term for tenants of comparable size and creditworthiness for comparable space in
the Building and other first class office buildings in the South Orange County
area as reasonably determined by Landlord, including, without limitation, the
then prevailing market rate as reasonably determined by Landlord for the parking
stalls allocated to Tenant under the terms of this Lease.

        B. To exercise its option, Tenant must deliver a binding (except as
provided in Section 31(C)(ii) below) notice to Landlord not less than nine (9)
months prior to the proposed commencement of the applicable Renewal Term.
Thereafter, the Market Rate for the Renewal Term shall be calculated pursuant to
Subsection C below and Landlord shall inform Tenant of the Market Rate. Such
calculations shall be final and shall not be recalculated at the actual
commencement of the Renewal Term. If Tenant fails to timely give its notice of
exercise, Tenant will be deemed to have waived its option to extend.

                                       36
<PAGE>   42

        C. Market Rate shall be determined as follows:

                (i) If Tenant provides Landlord with its binding notice of
        exercise pursuant to Subsection B above, then at some point between ten
        (10) and eight (8) months prior to the commencement of the applicable
        Renewal Term (or, at Landlord's election, at an earlier point), Landlord
        shall calculate and inform Tenant of the Market Rate. If Tenant rejects
        the Market Rate as calculated by Landlord, Tenant shall inform Landlord
        of its rejection within ten (10) days after Tenant's receipt of
        Landlord's calculation, and Landlord and Tenant shall commence
        negotiations to agree upon the Market Rate. If Tenant fails to timely
        reject Landlord's calculation of the Market Rate it will be deemed to
        have accepted such calculation. If Landlord and Tenant are unable to
        reach agreement within twenty-one (21) days after Landlord's receipt of
        Tenant's notice of rejection, then the Market Rate shall be determined
        in accordance with (ii) below.

                (ii) If Landlord and Tenant are unable to reach agreement on the
        Market Rate within said twenty-one (21) day period, then within seven
        (7) days, Landlord and Tenant shall each simultaneously submit to the
        other in a sealed envelope its good faith estimate of the Market Rate.
        If the higher of such estimates is not more than one hundred five
        percent (105%) of the lower, then the Market Rate shall be the average
        of the two. Otherwise, the dispute shall be resolved by arbitration in
        accordance with (iii) and (iv) below; provided that Tenant may instead,
        by written notice to Landlord given within seven (7) days after the
        exchange of estimates, rescind its exercise of the extension option, in
        which event this Lease shall expire at the end of the initial Term set
        forth in the Schedule (and if Tenant fails to deliver such written
        recision notice with such seven (7) day period, Tenant's notice of the
        extension of the Term shall be binding and the Base Rent for the Renewal
        Term shall be determined by arbitration as provided below).

                (iii) Within seven (7) days after the exchange of estimates, the
        parties shall select as an arbitrator an independent MAI appraiser with
        at least five (5) years of experience in appraising office space in the
        metropolitan area in which the Project is located (a "Qualified
        Appraiser"). If the parties cannot agree on a Qualified Appraiser, then
        within a second period of seven (7) days, each shall select a Qualified
        Appraiser and within ten (10) days thereafter the two appointed
        Qualified Appraisers shall select a third Qualified Appraiser and the
        third Qualified Appraiser shall be the sole arbitrator. If one party
        shall fail to select a Qualified Appraiser within the second seven (7)
        day period, then the Qualified Appraiser chosen by the other party shall
        be the sole arbitrator.

                (iv) Within twenty-one (21) days after submission of the matter
        to the arbitrator, the arbitrator shall determine the Market Rate by
        choosing whichever of the estimates submitted by Landlord and Tenant the
        arbitrator judges to be more accurate. The arbitrator shall notify
        Landlord and Tenant of its decision, which shall

                                       37
<PAGE>   43

        be final and binding. If the arbitrator believes that expert advice
        would materially assist him, the arbitrator may retain one or more
        qualified persons to provide expert advice. The fees of the arbitrator
        and the expenses of the arbitration proceeding, including the fees of
        any expert witnesses retained by the arbitrator, shall be paid by the
        party whose estimate is not selected. Each party shall pay the fees of
        its respective counsel and the fees of any witness called by that party.

        D. Tenant's option to extend this Lease is subject to the conditions
that: (i) on the date that Tenant delivers its final binding notice exercising
its option to extend, Tenant is not in default under this Lease after the
expiration of any applicable notice and cure periods, and (ii) Tenant shall not
have assigned this Lease, or sublet any portion of the Premises under a sublease
which is in effect at any time during the final 12 months prior to the
applicable Renewal Term.

        32. RIGHT OF FIRST REFUSAL. Subject to Subsection B below, Landlord
hereby grants to Tenant for the term set forth in this Section a right of first
refusal for space in Building 2 (27071 Aliso Creek Road) of the Project
(collectively, the "ROFR Space"), to be exercised in accordance with Subsection
A below. Tenant's right of first refusal with respect to the ROFR Space shall be
applicable only to Landlord's initial leasing of the ROFR Space; once any
portion of the ROFR Space has been leased (whether to Tenant or any other
party), Tenant shall have no further rights under this Section 32 with respect
to such portion of the ROFR Space.

        A. If Landlord desires to accept a bona fide offer to initially lease
any of the ROFR Space during the term of the Tenant's rights under this Section,
Landlord shall so notify Tenant ("Landlord's ROFR Notice") identifying the
applicable ROFR Space (the "Subject ROFR Space") and the basic economic terms as
elected by Landlord for such ROFR Space. Tenant shall notify Landlord within
three (3) business days of receipt of Landlord's ROFR Notice whether it desires
to lease the Subject ROFR Space on the terms set forth in Landlord's ROFR
Notice. If Tenant does not notify Landlord within said 3 business day period
that it will lease the Subject ROFR Space, Tenant shall be deemed to have
refused the Subject ROFR Space. After any refusal, Landlord shall be free to
lease such space to any party upon basic economic terms not materially less
favorable to Landlord for a period of six (6) months (and if Landlord leases
such space to any party upon basic economic terms not materially less favorable
to Landlord within such six (6) month period, Tenant shall have no further right
of first refusal for such Subject ROFR Space). If Landlord fails to so lease
such Subject ROFR Space within such six (6) month period, or if Landlord desires
to accept a bona fide offer for such Subject ROFR Space during such six (6)
month period on basic economic terms materially less favorable to Landlord,
Tenant shall again have a right of first refusal with respect to such Subject
ROFR Space on the terms and conditions set forth in this Section 32. If Tenant
exercises its right of first refusal with respect to the Subject ROFR Space,
such space shall be added to the Premises for all purposes of this lease for the
remaining Term of this Lease on (a) the terms specified in Landlord's ROFR
Notice, and (b) the terms of this Lease to the extent that they do not conflict
with the terms specified in

                                       38
<PAGE>   44

Landlord's ROFR Notice, except that the terms of Landlord's ROFR Notice shall
not apply during any Renewal Term, and instead, the terms of this Lease applying
to the remainder of the Premises during the Renewal Term shall also apply to the
Subject ROFR Space.

        B. Tenant's right of first refusal is subject to the conditions that:
(i) on the date that Tenant delivers its notice exercising its right of first
refusal, Tenant is not in default under this Lease after the expiration of any
applicable notice and cure periods, and (ii) Tenant shall not have assigned the
Lease, or sublet any portion of the Premises under a sublease which is in effect
at any time during the period commencing with Tenant's delivery of its notice
and ending on the date the ROFR Space is added to the Premises.

        C. Promptly after Tenant's exercise of its right of first refusal,
Landlord shall execute and deliver to Tenant an amendment to the Lease to
reflect changes in the Premises, Base Rent, Tenant's Proportionate Share and any
other appropriate terms changed by the addition of the ROFR Space. Within 15
days thereafter, Tenant shall execute and return the amendment.

                              RULES AND REGULATIONS

        1. Tenant shall not place anything, or allow anything to be placed near
the glass of any window, door, partition or wall which may, in Landlord's
judgment, appear unsightly from outside of the Project.

        2. The Project directory shall be available to Tenant solely to display
names and their location in the Project, which display shall be as directed by
Landlord.

        3. The sidewalks, halls, passages, exits, entrances, elevators and
stairways shall not be obstructed by Tenant or used by Tenant for any purposes
other than for ingress to and egress from the Premises. Tenant shall lend its
full cooperation to keep such areas free from all obstruction and in a clean and
sightly condition and shall move all supplies, furniture and equipment as soon
as received directly to the Premises and move all such items and waste being
taken from the Premises (other than waste customarily removed by employees of
the Building) directly to the shipping platform at or about the time arranged
for removal therefrom. The halls, passages, exits, entrances, elevators,
stairways, balconies and roof are not for the use of 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 Landlord, reasonably
exercised, shall be prejudicial to the safety, character, reputation and
interests of the Project. Neither Tenant nor any employee or invitee of Tenant
shall go upon the roof of the Project.

        4. The toilet rooms, urinals, wash bowls and other apparatuses shall not
be used for any purposes other than that for which they were constructed, and no
foreign substance of any kind whatsoever shall be thrown therein, and to the
extent caused by Tenant or its employees or invitees, the expense of any
breakage, stoppage or damage resulting from the violation of this rule shall be
borne by Tenant.

        5. Tenant shall not cause any unnecessary janitorial labor or services
by reason of Tenant's carelessness or indifference in the preservation of good
order and cleanliness.

        6. Tenant shall not install or operate any refrigerating, heating or air
conditioning apparatus, or carry on any mechanical business without the prior
written consent of Landlord; use the Premises for housing, lodging or sleeping
purposes; or permit preparation or warming of food in the Premises (warming of
coffee and individual meals with employees and guests excepted). Tenant shall
not occupy or use the Premises or permit the Premises to be occupied or used for
any purpose, act or thing which is in violation of any Governmental Requirement
or which may be dangerous to persons or property.

                                   APPENDIX C

                          TENANT IMPROVEMENT AGREEMENT

        1. INITIAL IMPROVEMENTS. Landlord shall cause to be performed the
improvements (the "Initial Improvements") in the Premises in accordance with
plans and specifications approved by Tenant and Landlord (the "Plans"), which
approvals shall not be unreasonably withheld. The Initial Improvements shall be
performed at the Tenant's cost, subject to the Landlord's Contribution
(hereinafter defined). The Initial Improvements shall include the installation
of a separate meter for Tenant's computer room (the "Meter").

        Landlord shall cause the Plans to be prepared, at Tenant's cost, by a
registered professional architect and mechanical and electrical engineer(s),
approved by the Landlord. Tenant shall within two (2) weeks after receipt of the
Plans either provide reasonable and detailed written comments to such Plans or
approve the same. Tenant shall be deemed to have approved such Plans if it does
not timely provide comments on such Plans. If Landlord provides Tenant with
revised Plans, Tenant shall within one week after receipt then either provide
reasonable and detailed written comments to such revised Plans or approve such
Plans. Tenant shall be deemed to have approved such revised Plans if Tenant does
not timely provide comments on such Plans. Tenant hereby acknowledges and agrees
that the Plans for the Initial Improvements must comply with all applicable
Governmental Requirements, but that Landlord's preparation of any of the Plans
(or any modifications or changes thereto) shall not impose upon Landlord or its
agents or representatives any obligation with respect to the design of the
Initial Improvements or the compliance of such Initial Improvements or the Plans
with applicable Governmental Requirements.

        Landlord, with consultation of Tenant, shall select a contractor to
perform the construction of the Initial Improvements. Landlord shall use
commercially reasonable efforts to cause the Initial improvements for each Phase
of the Premises to be substantially completed, except for minor "Punch List"
items, on or before the Estimated Commencement Date for such Phase of the
Premises specified in the Schedule to the Lease, subject to Tenant Delay (as
defined in Section 4 hereof) and Force Majeure.

        Landlord, or an agent of Landlord, shall provide project management
services in connection with the construction of the Initial Improvements and the
Change Orders (hereinafter defined). Such project management services shall be
performed, at Tenant's cost, for a fee of five percent (5%) of all costs related
to the preparation of the Plans and the construction of the Initial Improvements
and the Change Orders.

        2. CHANGE ORDERS. If, prior to the Commencement Date, Tenant shall
require improvements or changes (individually or collectively, "Change Orders")
to any of the Premises in addition to, revision of or substitution for the
Initial Improvements, Tenant shall deliver to Landlord for its approval plans
and specifications for such Change Orders. If Landlord does not approve of the
plans for Change Orders, Landlord shall advise Tenant of the revisions required.
Tenant shall revise and redeliver the plans and specifications to Landlord
within five (5) business days of Landlord's advice or Tenant shall be deemed to
have abandoned its request for such Change Orders. Tenant shall pay for all
preparations and revisions of plans and specifications, and the construction of
all Change Orders, subject to Landlord's Contribution.

                                   APPENDIX C
                                   Page 1 of 4

<PAGE>   55

        3. LANDLORD'S CONTRIBUTION. Landlord shall contribute toward the costs
incurred for the Initial Improvements and Change Orders for each Phase an amount
up to the following amount for each Phase of the Premises ("Landlord's
Contribution"):

<TABLE>
<CAPTION>
                                      Landlord's Contribution
<S>                                   <C>
        Phase A                             $393,860

        Phase B                             $203,700

        Phase C                             $203,700
</TABLE>

The costs of the Meter, up to a maximum of $500, shall be applied against
Landlord's Contribution. Landlord has no obligation to pay for costs of the
Initial Improvements or Change Orders for any Phase in excess of Landlord's
Contribution for such Phase. If the cost of the Initial Improvements and/or
Change Orders for any Phase exceeds the Landlord's Contribution for such Phase,
Tenant shall pay such overage to Landlord prior to commencement of construction
of the Initial Improvements and/or Change Orders for such Phase (and any unused
Landlord's Contribution for any Phase cannot be used to offset the cost of the
Initial Improvements and/or Change Orders for any other Phase).

        4. COMMENCEMENT DATE DELAY. The Commencement Date for each Phase of the
Premises shall be delayed beyond the Estimated Commencement Date for such Phase
of the Premises until the Initial Improvements for such Phase of the Premises
have been substantially completed (the "Completion Date"), except to the extent
that the delay shall be caused by any one or more of the following (a "Tenant
Delay"):

               (a) Tenant's request for Change Orders whether or not any such
Change Orders are actually performed; or

               (b) Contractor's performance of any Change Orders; or

               (c) Tenant's request for materials, finishes or installations
requiring unusually long lead times; or

               (d) Tenant's delay in reviewing, revising or approving plans and
specifications beyond the periods set forth herein; or

               (e) Tenant's delay in providing information critical to the
normal progression of the project. Tenant shall provide such information as soon
as reasonably possible, but in no event longer than one week after receipt of
such request for information from the Landlord; or

               (f) Tenant's delay in making payments to Landlord for costs of
the Initial Improvements and/or Change Orders in excess of the Landlord's
Contribution; or

                                   APPENDIX C
                                   Page 2 of 4

<PAGE>   56

         (g) Any other act or omission by Tenant, its agents, contractors or
persons employed by any of such persons.

If the Commencement Date for any Phase of the Premises is delayed for any
reason, then Landlord shall cause Landlord's Architect to certify the date on
which the Initial Improvements would have been completed but for such Tenant
Delay, or were in fact completed without any Tenant Delay.

         Without limiting the foregoing regarding Tenant Delay, if Landlord has
not substantially completed construction of the Initial Improvements for any
Phase of the Premises on or before the date which is fifteen (15) days after
Estimated Commencement Date for such Phase of the Premises (the "Outside Date")
as a result of a Landlord Delay, then as Tenant's sole remedy for the delay,
Tenant's obligation to pay Base Rent for the Phase of the Premises affected by
such Landlord Delay (but not any other portion of the Premises) shall be abated
after the Commencement Date for the Phase of the Premises so affected, for each
day of Landlord Delay beyond the applicable Outside Date by an amount equal to
$1.50 multiplied by the Rentable Area of the Phase of the Premises to which such
Landlord Delay applies, divided by the number of days in the calendar month to
which such abatement applies. Further, without limiting the foregoing regarding
Tenant Delay, if Landlord has not substantially completed construction of the
Initial Improvements for Phase A of the Premises on or before November 15, 1999
as a result of a Landlord Delay, than as Tenants' sole remedy for the delay,
Tenant may, on or before November 30, 1999, elect to terminate this Lease as to
the entire Premises by written notice to Landlord (in which event if Tenant
timely delivers such notice, this Lease shall thereafter terminate, excluding
any obligations which survive any termination and excluding any obligations to
pay for work performed prior to the date of such termination). If Tenant fails
to deliver notice of such termination on or before November 30, 1999, Tenant
shall be deemed to have elected not to terminate this Lease and the provisions
of the immediately preceding sentence shall be of no further force or effect. As
used herein "Landlord Delay" means any action or omission by Landlord that
actually delays the substantial completion of the Initial Improvements for the
Phase A Premises, and shall not include Tenant Delay or any delay resulting from
Force Majeure.

         5.  ACCESS BY TENANT PRIOR TO COMMENCEMENT OF TERM. Landlord at its
discretion may permit Tenant and its agents to enter any portion of the Premises
prior to the Commencement Date for such portion of the Premises to prepare the
Premises for Tenant's use and occupancy. Any such permission shall constitute a
license only, conditioned upon Tenant's:

         (a) working in harmony with Landlord and Landlord's agents,
contractors, workmen, mechanics and suppliers and with other tenants and
occupants of the Building;

         (b) obtaining in advance Landlord's approval of the contractors
proposed to be used by Tenant and depositing with Landlord in advance of any
work (i) security satisfactory to Landlord for the completion thereof, and (ii)
the contractor's affidavit for the proposed work and the waivers of lien from
the contractor and all subcontractors and suppliers of material; and

         (c) furnishing Landlord with such insurance as Landlord may require
against liabilities which may arise out of such entry.

                                  APPENDIX C
                                  Page 3 of 4

<PAGE>   57
        Landlord shall have the right to withdraw such license for any reason
upon twenty-four (24) hours' written notice to Tenant. Landlord shall not be
liable in any way for any injury, loss or damage which may occur to any of
Tenant's property or installations in the Premises prior to the Commencement
Date. Tenant shall protect, defend, indemnify and save harmless Landlord from
all liabilities, costs, damages, fees and expenses arising out of the
activities of Tenant or its agents, contractors, suppliers or workmen in the
Premises or the Building. Any entry and occupation permitted under this Section
shall be governed by Section 5 and all other terms of the Lease.

        6. MISCELLANEOUS.

        Tenant acknowledges and agrees that the construction of the Initial
Improvements in the Phase B Premises and Phase C Premises shall continue after
Tenant has taken occupancy of a portion of the Premises, and Tenant agrees that
such construction shall not affect Tenant's obligations under this Lease or
constitute an eviction of Tenant from the Premises. Terms used in this Appendix
C shall have the meanings assigned to them in this Lease. The terms of this
Appendix C are subject to the terms of this Lease.

                       FIRST AMENDMENT TO LEASE AGREEMENT

     THIS FIRST AMENDMENT TO LEASE AGREEMENT ("Amendment") is dated as of July
21, 1999, between CARRAMERICA REALTY CORPORATION ("Landlord"), and ZLAND,
Inc., a California corporation ("Tenant").

     A.   Landlord and Tenant entered into that certain Lease dated as of
February 26, 1999 (the "Lease"), with respect to certain premises located at
27081 Aliso Creek Road, Aliso Viejo, California. Unless otherwise defined in
this Amendment, initially-capitalized terms used herein shall have the meanings
set forth in the Lease.

     B.   Landlord and Tenant desire to amend the Lease upon the terms and
conditions set forth herein.

     NOW THEREFORE, in consideration of the foregoing Recitals, the mutual
covenants and agreements contained herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
Landlord and Tenant agree, and amend the Lease, as follows:

     1.   The following is hereby added to the end of Section 3 of Appendix C
to the Lease:

          If the costs of the Initial Improvements and Change Orders are in
     excess of the Landlord's Contribution, and so long as Tenant is not in
     default under this Lease, Landlord will lend Tenant an amount not to
     exceed, with respect to each Phase, an amount equal to One Dollar per
     gross rentable square foot of space in such Phase (the "Improvement
     Allowance") solely for the payment of the costs of the Initial
     Improvements and Change Orders for such Phase. The Improvement
     Allowance shall be calculated on a Phase by Phase basis, and any
     unused Improvement Allowance for any Phase may not be reallocated to,
     or used for, any other Phase. The entire Improvement Allowance funded
     by Landlord, together with interest thereon at the rate set forth
     herein, shall be paid by Tenant to Landlord as part of the Base Rent.
     For the purposes of determining the Base Rent, the "TI Rent Component"
     per month shall mean an amount equal to the total Improvement
     Allowance funded by Landlord, together with interest on such amount at
     a rate of eleven percent (11%) per annum from the date of disbursement
     by Landlord until repaid by Tenant, amortized in equal monthly
     installments over the initial term of this Lease. Landlord and Tenant
     agree that all unpaid amounts of the Improvement Allowance constitute
     Base Rent under this Lease. Without limiting any of the foregoing
     provisions, at Landlord's request, Tenant shall within five (5) days
     after such request, duly execute and deliver to Landlord a promissory
     note, in form and substance satisfactory to Landlord, evidencing
     Tenant's obligation to repay the Improvement Allowance with interest
     thereon as provided herein (the "Improvement Note"). Tenant
     acknowledges and agrees that (a) Tenant's failure to deliver the
     Improvement Note to Landlord as provided herein, or (b) any breach of
     any of the terms of the Improvement Note, shall constitute a
<PAGE>   68
     material breach and default under this Lease. Tenant's failure to execute
     and deliver the Improvement Note to Landlord as provided herein shall not
     affect Tenant's obligation to repay the Improvement Allowance together with
     interest thereon as provided herein. The Improvement Note may be prepaid by
     Tenant at any time. Any unpaid Improvement Allowance, together with
     interest thereon as provided herein, shall be immediately due and payable
     upon any default by Tenant under this Lease. Tenant agrees to pay any and
     all of Landlord's attorneys' fees and costs relating to the enforcement of
     Landlord's rights under the Improvement Note or with respect to the
     repayment of the Improvement Allowance.

     2.   Section 11 of the Schedule to the Lease is hereby deleted and the
following substituted therefor:

          Base Rent shall be and mean the sum of the applicable Base Component
     set forth below plus the applicable TI Rent Component (as defined in
     Appendix C, as amended by this Amendment) for all of the Phases. The Base
     Component is as follows:

form of Appendix A attached hereto, substituted therefor.

     4.   Upon any determination of the TI Rent Component for any Phase the
amount of the Security Deposit shall be recalculated taking into account the
addition of such TI Rent Component to the Base Rent and Tenant shall, within
five (5) days after written notice from Landlord, deliver to Landlord the
amount necessary to cause the Security Deposit then held by Landlord to equal
such recalculated amount.

     5.   Landlord and Tenant acknowledge that the Change Orders described in
the April 13, 1999 letter from Landlord to Tenant were implemented by Landlord
and Tenant and any contrary references in the Lease are hereby amended
accordingly.

     6.   This Amendment shall be governed by, and construed and enforced in
accordance with, the laws of the State of California.

     7.   This Amendment may be executed in any number of counterparts, each of
which when so executed and delivered shall be deemed to be an original and all
of which counterparts taken together shall constitute but one and the same
instrument. Signature pages may be detached from the counterparts and attached
to a single copy of this Amendment to physically form one document.

     8.   Tenant hereby acknowledges and reaffirms its obligations under the
Lease, as such Lease has been amended by this Amendment, and agrees that any
reference made in any other document to the Lease shall mean the Lease as
amended pursuant to this Amendment. Except as expressly provided herein, the
Lease remains unmodified and in full force and effect. Any breach by Tenant of
this Amendment, including any exhibit hereto, shall constitute a breach and
default by Tenant under the Lease.

     9.   Time is of the essence with respect to each provision of this
Agreement.

                                   WITNESSETH

     A.     Pursuant to that certain Lease dated February 26, 1999, by and
between Landlord and Tenant (the "LEASE"), Tenant leased certain space (the
"ORIGINAL PREMISES") in a building known as Pacific Corporate Plaza, located at
27081 Aliso Creek Road, Aliso Viejo, California. Pursuant to that certain First
Amendment to Lease dated as of July 21, 1999, Landlord and Tenant amended the
Lease. All capitalized terms in this Second Amendment shall have the same
meanings as in the Lease, as amended by the First Amendment, unless another
meaning is clearly indicated here.

     B.     Landlord and Tenant desire to amend the Lease to include 26,766
rentable square feet of space (the "ADDITIONAL PREMISES") in the building at
27071 Aliso Creek Road, Aliso Viejo, California (the "27071 BUILDING"), which
space is more particularly identified on Exhibit A, which is attached to this
Second Amendment.

     C.     Landlord and Tenant desire to amend the Lease further upon the
terms and conditions set forth herein.

     NOW, THEREFORE, in consideration of the foregoing Recitals, which are
incorporated herein by this reference, the mutual promises and conditions
contained herein, and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, Landlord and Tenant hereby
agree as follows:

1.   Lease of Additional Premises. Landlord hereby leases to Tenant, and Tenant
     hereby leases from Landlord, the Additional Premises.

2.   Term of Lease of Additional Premises. The Term of the Lease of the
     Additional Premises shall commence on the Effective Date (as defined
     herein), and shall terminate on the last day of the month which is 60
     months after the month following the Effective Date of this Second
     Amendment. The "EFFECTIVE DATE" shall be March 1, 2000.

3.   Rentable Square Feet of the Premises. As of the Effective Date, the
     Rentable Square Feet of the Original Premises and the Additional Premises
     is hereby agreed by the parties to be 66,829 rentable square feet.

4.   Term of Lease of Original Premises. The Term of the Lease of the Original
     Premises shall be extended from December 01, 2004 to February 28, 2005
     "Original Premises Extension Term" to be coterminous with the Additional
     Premises Term.

                                       1
<PAGE>   76
5.     Tenant's Proportionate Share. The parties agree that as of the Effective
       Date, Tenant's Proportionate Share of the 27071 Building shall be 51.9%,
       and Tenant's Proportionate Share of the Project is amended and shall be
       52.7%.

6.     Security Deposit. The Security Deposit for the Original Premises is not
       changed by this Second Amendment. As of the Effective Date, to secure
       Tenant's obligations with respect to the Additional Premises. Tenant
       shall be required to provide a letter of credit from a bank reasonably
       acceptable to Landlord, which letter of credit shall be in favor of
       Landlord and in the amount of $300,000. On each anniversary of the
       Effective Date, the available credit under such letter of credit may be
       reduced by an additional $75,000, provided that Tenant has on hand cash
       or other liquid assets in such amount which is adequate, in Landlord's
       reasonable judgment, to meet all of Tenant's financial obligations
       during the Term. Notwithstanding the foregoing, except as otherwise
       provided herein, the available credit under the letter of credit shall
       at no time be less than the amount of one month's Base Rent on the
       Premises. Tenant shall have the right at any time to substitute cash for
       the letter of credit, provided that the amount of any cash Security
       Deposit shall be the same amount as the available credit under the
       letter of credit, but shall in no event be less than 110% of the amount
       of one month's Base Rent on the Additional Premises. In the event that
       Tenant makes a successful public offering of its capital stock, which
       stock is traded on a major stock exchange, then Tenant's obligation to
       maintain the letter of credit shall terminate, and Tenant shall deposit
       with Landlord in cash an amount equal to 110% of the amount of one
       month's Base Rent at that time on the Additional Premises. The Security
       Deposit for the Additional Premises is subject to the provisions of
       Section 20 of the Lease, and Landlord may make one or more drafts on the
       letter of credit or use any substitute cash Security Deposit as set
       forth in Section 20 of the Lease.

7.     Base Rent for the Additional Premises. Tenant agrees that Tenant's
       obligations with respect to payment of Base Rent, Operating Cost Share
       Rent, Tax Share Rent and Additional Rent on the Original Premises, as set
       forth in the Lease and the First Amendment, shall be unchanged and shall
       remain in full force and effect for the Term. As of the Effective Date,
       Tenant shall commence to pay Base Rent on the Additional Premises at the
       rate of $1.03 per rentable square foot multiplied by 26,766 rentable
       square feet. On the earlier to occur of (a) the date of Substantial
       Completion of the Tenant Improvements (as defined in Exhibit B hereto),
       or (b) September 1, 2000, Base Rent on the Additional Space shall be
       adjusted, and shall be $1.40 per rental square foot multiplied by 26.766
       rentable square feet. On each anniversary of the Effective Date, Base
       Rent on the Additional Premises shall increased at the rate of $0.05 per
       rentable square foot for each rentable square foot of the Additional
       Premises.

8.     Base Rent for the Original Premises during the "Original Premises
       Extension Term". During the three (3) month "Extension Term" for the
       Original Premises, Tenant shall pay a base rent of $1.60.

9.     Operating Cost Share Rent, Tax Share Rent and Additional Rent. As of the
       Effective Date, Tenant shall pay monthly Tenant's Proportionate Share of
       Operating Cost Share Rent, Tax Share Rent and Additional Rent, as
       defined in the Lease, on the Additional Premises.

10.    Signage. As of the Effective Date, Tenant shall have the right to have
       its name placed in the Directory of the Building, at no cost to Tenant.

       have the right to install and maintain one "EYEBROW" sign on the

<PAGE>   77
     Building, to the extent permitted by Governmental Requirements. Upon the
     expiration or earlier termination of the Lease, Tenant shall remove the
     Eyebrow sign and repair all damage caused thereby and restore the
     applicable portion of the Building to its condition prior to installation
     of the Eyebrow sign. Tenant shall also have the right, subject to
     Landlord's reasonable approval and to the extent permitted by Governmental
     Requirements, to install and maintain custom signs on the walls of the
     elevator lobby of the second floor of the Building, and on entrance doors
     to any suite on the second floor. All costs and expenses in connection with
     the installation, maintenance, or removal of any sign shall be Tenant's
     sole responsibility.

11.  Confirmation of Other Obligations. All other obligations of Tenant and
     Landlord in respect of the Lease shall remain unchanged, and the parties
     hereby confirm those obligations.

12.  Stipulation of No Event of Default. The parties stipulate that upon
     execution of this Second Amendment, there will be no existing and
     continuing event of default in the obligations of either party with respect
     to the Lease.

13.  Ratification of Lease. Except as expressly modified herein, all terms and
     conditions of the Lease, as amended, are hereby ratified and shall remain
     in full force and effect.

14.  Counterparts. This Second Amendment may be executed in any number of
     counterparts, each of which shall be deemed an original, but all of which
     when taken together shall constitute one and the same instrument. Each
     counterpart may be detached therefrom without impairing the legal effect of
     the signatures thereon, provided such signature page is attached to any
     other counterpart identical thereto.

                          TENANT IMPROVEMENT AGREEMENT

     1.   TENANT IMPROVEMENTS. Landlord shall cause to be performed the
improvements (the "Tenant Improvements") in the Additional Premises in
accordance with plans and specifications approved by Tenant and Landlord (the
"Plans"), which approvals shall not be unreasonably withheld. The Tenant
Improvements shall be performed at the Tenant's cost, subject to the Landlord's
Contribution (hereinafter defined).

     Tenant shall cause the Plans to be prepared, at Tenant's cost, by a
registered professional architect and mechanical and electrical engineer(s).
Such engineer(s) shall be approved, in advance, by the Landlord. Prior to the
close of business on February 15, 2000, Tenant shall furnish the initial draft
of the Plans to Landlord for Landlord's review and approval. Landlord shall
provide reasonable comments to such Plans within one (1) week or approve the
same. Landlord shall be deemed to have approved such Plans if it does not timely
provide reasonable comments on such Plans. If Landlord provides Tenant with
reasonable comments to the Tenant draft of the Plans, Tenant shall provide
revised Plans to Landlord incorporating Landlord's comments. Tenant hereby
agrees that the Plans for the Tenant Improvements shall comply with all
applicable Governmental Requirements. The fact that Landlord may have caused to
be prepared any of the Plans (or any modifications or changes thereto) shall
not impose upon Landlord or its agents or representatives any obligation with
respect to the design of the Tenant Improvements or the compliance of such
Tenant Improvements or the Plans with applicable Governmental Requirements.

     Landlord, with consultation of Tenant, shall select a contractor to perform
the construction of the Tenant Improvements. Landlord shall use commercially
reasonable efforts to cause the Tenant Improvements to be substantially
completed, except for minor "Punch List" items, except for Tenant Delays.

     Landlord, or an agent of Landlord, shall provide project management
services in connection with the construction of the Tenant Improvements and the
Change Orders (hereinafter defined). Such project management services shall be
performed, at Tenant's cost, for a fee of five percent (5%) of all costs related
to the preparation of the Plans and the construction of the Tenant Improvements
and the Change Orders.

     2.   CHANGE ORDERS. If, prior to the Commencement Date, Tenant shall
require improvements or changes (individually or collectively, "Change Orders")
to the Premises in addition to, revision of or substitution for the Tenant
Improvements, Tenant shall deliver to Landlord for its approval plans and
specifications for such Change Orders. If Landlord does not approve of the plans
for Change Orders, Landlord shall advise Tenant of the revisions required.
Tenant shall revise and redeliver the plans and specifications to Landlord
within five (5) business days of Landlord's advice or Tenant shall be deemed to
have abandoned its request for such Change Orders. Tenant shall pay for all
preparations and revisions of plans and specifications, and the construction of
all Change Orders, subject to Landlord's Contribution.

                                       6
<PAGE>   81
      3.    LANDLORD'S CONTRIBUTION. Landlord shall contribute an amount up to
$588,852 ("Landlord's Contribution") toward the costs incurred for the Tenant
Improvements and Change Orders. Landlord has no obligation to pay for costs of
the Tenant Improvements or Change Orders in excess of Landlord's Contribution.
If the cost of the Tenant Improvements and/or Change Orders is expected to
exceed the Landlord's Contribution, Tenant shall pay such overage to Landlord
prior to commencement of construction of the Tenant Improvements and/or Change
Orders.

      4.    SUBSTANTIAL COMPLETION DELAY. Tenant Delay will only be applicable
should Tenant Improvements proceed and would have had a substantial completion
date prior to September 1, 2000. Any one or more of the following will
constitute a delay in Substantial Completion of the Tenant Improvements and be
noted as a "Tenant Delay":

            (a)   Tenant's request for Change Orders whether or not any such
Change Orders are actually performed; or

            (b)   Contractor's performance of any Change Orders; or

            (c)   Tenant's request for materials, finishes or installations
requiring unusually long lead times; or

            (d)   Tenant's delay in reviewing, revising or approving plans and
specifications beyond the periods set forth herein; or

            (e)   Tenant's delay in providing information critical to the
normal progression of the project. Tenant shall provide such information as
soon as reasonably possible, but in no event longer than one week after receipt
of such request for information from the Landlord; or

            (f)   Tenant's delay in making payments to Landlord for costs of
the Tenant Improvements and/or Change Orders in excess of the Landlord's
Contribution; or

            (g)   Any other act or omission by Tenant, its agents, contractors
or persons employed by any of such persons.

If the Effective Date is delayed for any reason, then Landlord shall cause
Landlord's Construction Manager and Landlords Architect to certify the date on
which the Tenant Improvements would have been completed but for such Tenant
Delay, or were in fact completed without any Tenant Delay, and such date shall
be the Effective Date.

      Prior to Tenant's occupancy of the Premises, Landlord and Tenant shall
agree to a punch list of items to be corrected.

      5. ACCESS BY TENANT PRIOR TO COMMENCEMENT OF TERM. Landlord at its
discretion may permit Tenant and its agents to enter the Premises prior to the
Effective Date to prepare the Premises for Tenant's use and occupancy. Any such
permission shall constitute a license only, conditioned upon Tenant's:

      (a)   working in harmony with Landlord and Landlord's agents,
contractors, workmen, mechanics and suppliers and with other tenants and
occupants of the Building;

                                       7
<PAGE>   82
     (b)  obtaining in advance Landlord's approval of the contractors proposed
to be used by Tenant and depositing with Landlord in advance of any work (i)
security satisfactory to Landlord for the completion thereof, and (ii) the
contractor's affidavit for the proposed work and the waivers of lien from the
contractor and all subcontractors and suppliers of material; and

2.   DELIVERY OF SERVICES; TERMS; FEES.

     2.1  Delivery of Services.

          (a) General. By submitting an Order Form, Customer agrees to take and
pay for, and, by accepting the Order Form, Exodus agrees to provide, the
Service(s) during the Initial Term and for any Renewal Term, as specified in
paragraph 2.2(b) below.

          (b) Delivery of Supplemental Services. The purpose of this provision
is to enable Exodus to provide Customer with certain limited services and
equipment needed by Customer on a "one-off" or emergency basis ("Supplemental
Services") where such services are not included within the scope of the
Services as described in the Specification Sheets and/or Statement of Work.
Supplemental Service may include, as an example, a request from Customer to
Exodus via telephone that Exodus immediately replace a problem Customer server
with an Exodus server for a temporary period of time. Exodus shall notify
Customer of the fees for any Supplemental Services requested by Customer and
obtain Customer's approval prior to providing such services. In the event
Exodus reasonably determines that Supplemental Services are required on an
emergency basis, Exodus may provide such services without the consent of
Customer, thereafter provide notice of the services to Customer and bill
Customer a reasonable fee for such services. Customer agrees to pay Exodus the
fees charged by Exodus for Supplemental Services. Customer will be charged for
Supplemental Services in the invoice issued the month following delivery of the
services. Exodus will use commercially reasonable efforts to provide
Supplemental Services, provided that Exodus has no obligation to determine the
need for or provide Supplemental Services. All Supplemental Services provided
pursuant to this paragraph 2.1(b) are provided on an "as-is" basis and exclude
warranties of any kind, whether express or implied.

     2.2  Term.

          (a) Term Commencement. The term for each Service will commence on the
Service Commencement Date indicated in the Notice of Service Commencement
delivered by Exodus to Customer when Exodus begins providing each Service to
Customer.

          (b) Renewal Term(s). Each Service will continue automatically for
additional terms equal to the Initial Term ("Renewal Term") unless Customer
notifies Exodus in writing at least thirty (30) days prior to the end of the
Initial Term or a Renewal Term, as applicable, that it has elected to terminate
such Service, in which case such Service shall terminate at the end of such
term. The termination of any Service will not affect Customer's obligations to
pay for other Service(s). Notwithstanding the foregoing, Exodus may change or
increase the prices it charges Customer for any Service at any time after the
Initial Term effective thirty (30) days after providing notice to Customer.
This paragraph 2.2(b) does not apply to Exodus Supplied Equipment which is only
provided for the Initial Term.

3.  FEES AND PAYMENT TERMS.

     3.1  Fees and Expenses. Customer will pay all fees due according to the
prices and terms listed in the Order Form(s). The prices listed in the Order
Form(s) will remain in effect during the Initial Term indicated in the Order
Form(s) and will continue thereafter, unless modified in accordance with Section
2.2. Customer also agrees to reimburse Exodus for actual out-of-pocket
reasonable expenses incurred in providing Professional Services to Customer.

     3.2  Payment Terms. On the Service Commencement Date for each Service,
Customer will be billed an amount equal to all non-recurring charges indicated
in the Order Form and the monthly recurring charges for the first month of the
term. Monthly recurring charges for all other months will be billed in advance
of the provision of Services. All other charges for Services received and
expenses incurred for Professional Services during a month (e.g., bandwidth
usage fees, travel expenses) will be billed at the end of the month in which
the Services were provided. Payment for all fees is due upon receipt of each
Exodus invoice. All payments will be made in the United States in U.S. dollars.

     3.3  Late Payments. Any payment not received within thirty (30) days of the
invoice date will accrue interest at a rate of one and one-half percent
(1 1/2%) per month, or the highest rate allowed by applicable law, whichever is
lower. If Customer is delinquent in its payments, Exodus may, upon written
notice to Customer, modify the payment terms to require full payment before the
provision of all Services and Exodus Supplied Equipment or require other
assurances to secure Customer's payment obligations hereunder.

     3.4  Taxes. All fees charged by Exodus for Services are exclusive of all
taxes and similar fees now in force or enacted in the future imposed on the
transaction and/or the delivery of Services, all of which Customer will be
responsible for and will pay in full, except for taxes based on Exodus' net
income.

other party's Confidential Information and will take reasonable precautions to
protect the confidentiality of such information, at least as stringent as it
takes to protect its own Confidential Information.

          (b) Exceptions. Information will not be deemed Confidential
Information hereunder if such information: (i) is known to the receiving party
prior to receipt from the disclosing party directly or indirectly from a source

receiving party directly or indirectly from a source other than one having an
obligation of confidentiality to the disclosing party; (iii) becomes publicly
known or otherwise ceases to be secret or confidential, except through a breach
of this Agreement by the receiving party; or (iv) is independently developed
by the receiving party. The receiving party may disclose Confidential
Information pursuant to the requirements of a governmental agency or by
operation of law, provided that it gives

                                                                          PAGE 2

contrary in this Agreement, Exodus will not be prohibited or enjoined at any

Customer's request in accordance with paragraph 5.2(d) below, credit Customer's
account as described below (the "Service Level Warranty"). The Service Level
Warranty shall not apply to any services other than bandwidth and facility

outside of Exodus' reasonable control; (ii) that resulted from any actions or
inactions of Customer or any third parties; or (iii) that resulted from
Customer's equipment and/or third party equipment (not within the sole control
of Exodus).

          (a)  Service Warranty Definitions. For purposes of this Agreement,
the following definitions shall apply only to the Services (not including
Professional Services).

               (i)  "Downtime" shall mean sustained packet loss in excess of
fifty percent (50%) within Exodus' U.S. network for fifteen (15) consecutive
minutes due to the failure of Exodus to provide Service(s) for such period.

Customer shall be eligible to receive from Exodus a Service Credit for each
Downtime period. Examples: If Customer experiences one Downtime period, it
shall be eligible to receive one Service Credit. If Customer experiences two
Downtime periods, either from a single event or multiple events, it shall be
eligible to receive two Service Credits.

                                                                          PAGE 3
<PAGE>   4

          (c) Performance Problem; Packet Loss and Latency. In the event that

Performance Problem, Exodus will take all actions necessary to determine the
source of the Performance Problem.

               (i) Time to Discover Source of Performance Problem;
Notification of Customer. Within two (2) hours of discovering or receiving
notice of the Performance Problem, Exodus will determine whether the source of
the Performance Problem is limited to the Customer Equipment and the Exodus
equipment connecting the Customer Equipment to the Exodus LAN. If Exodus
determines that the Customer Equipment and Exodus connection are not the source
of the Performance Problem, Exodus will determine the source of the Performance
Problem within an additional two (2) hour period. In any event, Exodus will
notify Customer of the source of the Performance Problem within sixty (60)
minutes of identifying the source.

               (ii) Remedy of Packet Loss and Latency. If the source of the
Performance Problem is within the sole control of Exodus, Exodus will remedy
the Performance Problem within two (2) hours of determining the source of the
Performance Problem. If the source of and remedy to the Performance Problem
reside outside of the Exodus LAN or WAN, Exodus will use commercially
reasonable efforts to notify the party(ies) responsible for the source of the
Performance Problem and cooperate with it (them) to resolve such problem as
soon as possible.

within the time periods described in subsection (i) above and/or; (B) is the
sole source of the Performance Problem and is unable to remedy such Performance
Problem within the time period described in subsection (ii) above, Exodus will
deliver a Service Credit to Customer for each two (2) hour period in excess of
the time periods of identification and resolution described above.

          (d) Customer Must Request Service Credit. In order to receive any of
the Service Credits described in this Section 5.2, Customer must notify Exodus
within seven (7) days from the time Customer becomes eligible to receive a
Service Credit. Failure to comply with this requirement will forfeit
Customer's right to receive a Service Credit.

aggregate maximum number of Service Credits to be issued by Exodus to Customer
for any and all Downtime periods and Performance Problems that occur in a
single calendar month shall not exceed seven (7) Service Credits. A Service
Credit shall be issued in the Exodus invoice in the month following the
Downtime or Performance Problem, unless the Service Credit is due in Customer's
final month of Service. In such case, a refund for the dollar value of the
Service Credit will be mailed to Customer. Customer shall also be eligible to
receive a pro-rata refund for (i) Downtime periods and Performance Problems for
which Customer does not receive a Service Credit and (ii) any Services Exodus
does not deliver to Customer for which Customer has paid.

          (f) Termination Option for Chronic Problems. Customer may terminate
this Agreement for cause and without penalty by notifying Exodus within five
(5) days following the end of a calendar month in the event either of the
following occurs: (i) Customer experiences more than fifteen (15) Downtime
periods resulting from three (3) or more nonconsecutive Downtime events during
the calendar month; or (ii) Customer experiences more than eight (8)
consecutive days of Downtime due to any single event. Such termination will be

ONLY APPLY TO THE BANDWIDTH AND FACILITIES SERVICE(S) PROVIDED BY EXODUS AND,
DOES NOT APPLY TO (i) ANY PROFESSIONAL SERVICES; (ii) ANY SUPPLEMENTAL
SERVICES; AND (iii) ANY SERVICE(S) THAT EXPRESSLY EXCLUDE THIS SERVICE LEVEL,

SECTION 5.2 STATES CUSTOMER'S SOLE AND EXCLUSIVE REMEDY FOR ANY FAILURE BY
EXODUS TO PROVIDE SERVICE(S).

     5.3  Service Performance Warranty. Exodus warrants that it will perform
the Services in a manner consistent with industry standards reasonably

warranties for Service(s) related to Exodus Supplied Equipment, Customer
acknowledges and agrees that its use and possession of the Exodus Supplied
Equipment by Customer shall be subject to and controlled by the terms of any
manufacturer's or, if appropriate, supplier's warranty, and Customer agrees to
look solely to the manufacturer or, if appropriate, supplier with respect to
all mechanical, service and other claims, and the right to enforce all
warranties made by said manufacturer are hereby, to the extent Exodus has the
right, assigned to Customer solely for the Initial Term.

THE SERVICES IS AT ITS OWN RISK. EXODUS DOES NOT MAKE, AND HEREBY DISCLAIMS, ANY
AND ALL OTHER EXPRESS AND/OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO,
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE NONINFRINGEMENT

PRACTICE. EXODUS DOES NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED,

     5.6 Disclaimer of Actions Caused by and/or Under the Control of Third
Parties. EXODUS DOES NOT AND CANNOT CONTROL THE FLOW OF DATA TO OR FROM EXODUS'
NETWORK AND OTHER PORTIONS OF THE INTERNET. SUCH FLOW DEPENDS IN LARGE PART ON
THE PERFORMANCE OF INTERNET SERVICES PROVIDED OR CONTROLLED BY THIRD PARTIES. AT
TIMES, ACTIONS OR INACTIONS OF SUCH THIRD PARTIES CAN IMPAIR OR DISRUPT
CUSTOMER'S CONNECTIONS TO THE INTERNET (OR PORTIONS THEREOF). ALTHOUGH EXODUS
WILL USE COMMERCIALLY REASONABLE EFFORTS TO TAKE ALL ACTIONS IT DEEMS
APPROPRIATE TO REMEDY AND AVOID SUCH EVENTS, EXODUS CANNOT GUARANTEE THAT SUCH
EVENTS WILL NOT OCCUR. ACCORDINGLY, EXODUS DISCLAIMS ANY AND ALL LIABILITY
RESULTING FROM OR RELATED TO SUCH EVENTS.

6. CUSTOMER OBLIGATIONS.

     6.1 Warranties of Customer.

         (a) General. Customer represents and warrants that (i) it has the legal
right and authority, and will continue to own or maintain the legal right and
authority, during the term of this Agreement, to place and use any Customer
Equipment as contemplated under this Agreement; (ii) the performance of its
obligations and use of the Services (by Customer, its customers and users) will
not violate any applicable laws, regulations or the Rules and Regulations or
cause a breach of any agreements with any third parties or unreasonably
interfere with other Exodus customers' use of Exodus services, and (iii) all
equipment, materials and other tangible items placed by Customer at Internet
Data

                                                                          PAGE 4
<PAGE>   5
Centers will be used in compliance with all applicable manufacturer
specifications.

          (b) Breach of Warranties. In the event of any breach of any of
foregoing warranties, in addition to any other remedies available at law or in
equity, Exodus will have the right, in its sole reasonable discretion, to
suspend immediately any related Services if deemed reasonably necessary by
Exodus to prevent any harm to Exodus and its business. Exodus will provide
notice and opportunity to cure if practicable depending on the nature of the
breach. Once cured, Exodus will promptly restore the Service(s).

     6.2  Compliance with Law and Rules and Regulations. Customer agrees that it
will use the Service(s) only for lawful purposes and in accordance with this
Agreement. Customer will comply at all times with all applicable laws and
regulations and the Rules and Regulations, as updated by Exodus from time to
time. The Rules and Regulations are incorporated herein and made a part hereof
by this reference. Exodus may change the Rules and Regulations upon fifteen (15)
days' notice to Customer, which notice may be provided by posting such new Rules
and Regulations at the Exodus Web site www.exodus.net. Customer agrees that it
has received, read and understands the current version of the Rules and
Regulations. The Rules and Regulations contain restrictions on Customer's and
Customer's users' online conduct (including prohibitions against unsolicited
commercial email) and contain financial penalties for violations of such
restrictions. Customer agrees to comply with such restrictions and, in the event
of a failure to comply, Customer agrees to pay the financial penalties in
accordance with the Rules and Regulations. Customer acknowledges that Exodus
exercises no control whatsoever over the content of the information passing
through customer's site(s) and that it is the sole responsibility of Customer to
ensure that the information it and its users transmit and receive complies with
all applicable laws and regulations and the Rules and regulations.

     6.3  Access and Security. Except with the advanced written consent of
Exodus, Customer's access to the Internet Data Centers will be limited solely to

written consent of Exodus (which may be withheld in its sole discretion), resell
the Services to any third parties or connect Customer Equipment directly to
anything other than the Exodus network, equipment and facilities.

     6.5  Relocation of Customer Equipment. In the event that it becomes
necessary to relocate the Customer Equipment to another Customer Area or
Internet Data Center operated by Exodus, Customer will cooperate in good faith
with Exodus to facilitate such relocation, provided that such relocation is

including all documents incorporated herein by reference, constitutes the
complete and exclusive agreement between the parties with respect to the
subject matter hereof, and supersedes and replaces any and all prior or
contemporaneous discussions, negotiations, understandings and agreements,
written and oral, regarding such subject matter. Any additional or different
