     2.1    LETTING. Lessor hereby leases to Lessee, and Lessee hereby leases
from Lessor, the Premises, for the term, at the rental, and upon all of the
terms, covenants and conditions set forth in this Lease. Unless otherwise
provided herein, any statement of size set forth in this Lease, or that may have
been used in calculating Rent, is an approximation which the Parties

                                        2
<Page>

agree is reasonable and any payments based thereon are not subject to revisions,
whether or not the actual size is more or less.

     2.2    CONDITION. Lessor shall deliver that portion of the Premises
contained within the Building ("UNIT") to Lessee broom clean and free of debris
on the Commencement Date or the Early Possession Date, whichever first occurs
("START DATE"), and, so long as the required service contracts described in
Paragraph 7.1(b) below are obtained by Lessee and in effect within thirty days
following the Start Date, warrants that the existing electrical, plumbing, fire
sprinkler, lighting, heating, ventilating and air conditioning systems ("HVAC"),
loading doors, if any, and any all other such elements in the Units, other than
those constructed by Lessee, shall be in good operating condition on said date
and that the structural elements of the roof, bearing walls and foundation of
the Unit shall be free of material defects. If a non-compliance with such
warranty exists as of the Start Date, or if one of such systems or elements
should malfunction or fail within the appropriate warranty period, Lessor shall,
as Lessor's sole obligation with respect to such matter, except as otherwise
provided in this Lease, promptly after receipt of written notice from Lessee
setting forth with specificity the nature and extent of such non-compliance,
malfunction or failure, rectify same at Lessor's expense. The warranty periods
shall be as follows: (i) 6 months as to the HVAC systems, and, (ii) 30 days as
to the remaining systems and other elements of the Unit. If Lessee does not give
Lessor the required notice within the appropriate warranty period, correction of
any such non-compliance, malfunction or failure shall be the obligation of
Lessee at Lessee's sole cost and expense (except for the repairs to the tire
sprinkler systems, root, foundations, and/or bearing walls - see Paragraph 7).

     2.3    COMPLIANCE. Lessor warrants that the improvements on the Premises
and the Common Areas comply with the building codes that were in effect at the
time that each such improvement, or portion thereof, was constructed, and also
with all applicable laws, covenants or restrictions of record, regulations, and
ordinances in effect on the Start Date ("APPLICABLE REQUIREMENTS"). Said
warranty does not apply to the use to which Lessee will put the premises or to
any Alterations or Utility Installations (as defined in Paragraph 7.3(a)) made
or to be made by Lessee. NOTE: Lessee is responsible for determining whether or
not the Applicable Requirements, and especially the zoning, are appropriate for
Lessee's intended use, and acknowledges that past uses of the Premises may no
longer be allowed. If the Premises do not comply with said warranty, Lessor
shall, except as otherwise provided, promptly after receipt of written notice
from Lessee setting forth with specificity the nature and extent of such
non-compliance, rectify the same at Lessor's expense. If Lessee does not give
Lessor written notice of a non-compliance with this warranty within forty-five
(45) days following the Start Date, correction of that non-compliance shall be
the obligation of Lessee at Lessee's sole cost and expense. If the Applicable
Requirements are hereafter changed so as to require during the term of this
lease the construction of an addition to or an alteration of the Unit, Premises
and/or Building, the remediation of any Hazardous Substance, or the
reinforcement or other physical modification of the Unit, Premises and/or
Building ("CAPITAL EXPENDITURE"), Lessor and Lessee shall allocate the cost of
such work as follows:

            (a)  Subject to Paragraph 2.3(c) below, if such Capital Expenditures
are required as a result of the specific and unique use of the Premises by
Lessee as compared with uses by tenants in general, Lessee shall be fully
responsible for the cost thereof, provided, however that if such Capital
Expenditure is required during the last 2 years of this Lease and the

                                        3
<Page>

cost thereof exceeds 6 months' Base Rent, Lessee may instead terminate this
Lease unless Lessor notifies Lessee, in writing, within 10 days after receipt of
Lessee's termination notice that Lessor has elected to pay the difference
between the actual cost thereof and the amount equal to 6 months' Base Rent. If
Lessee elects termination, Lessee shall immediately cease the use of the
Premises which requires such Capital Expenditure and deliver to lessor written
notice specifying a termination date at least 90 days thereafter. Such
termination date shall, however, in no event be earlier than the last day that
Lessee could legally utilize the Premises without commencing such Capital
Expenditure.

            (b)  If such Capital Expenditure is not the result of the specific
and unique use of the Premises by Lessee (such as, governmentally mandated
seismic modifications), then Lessor and Lessee shall allocate the obligation to
pay for the portion of such costs reasonably attributable to the premises
pursuant to the formula set out in Paragraph 7.1(d); provided, however, that if
such Capital Expenditure is required during the last 2 years of this Lease or if
Lessor reasonably determines that it is not economically feasible to pay its
share thereof, Lessor shall have the option to terminate this Lease upon 90 days
prior written notice to Lessee unless Lessee notifies Lessor, in writing, within
10 days after receipt of Lessor's termination notice that Lessee will pay for
such Capital Expenditure. If Lessor does not elect to terminate, and falls to
lender its share of any such Capital Expenditure, Lessee may advance such funds
and deduct same, with interest, from Rent until Lessor's share of such costs
have been fully paid. If Lessee is unable to finance Lessor's share, or if the
balance of the Rent due and payable for the remainder of this Lease is not
sufficient to fully reimburse Lessee on an offset basis. Lessee shall have the
right to terminate this Lease upon 30 days written notice to Lessor.

            (c)  Notwithstanding the above, the provisions concerning Capital
Expenditures are intended to apply only to non-voluntary, unexpected, and new
Applicable Requirements. If the Capital Expenditures are instead triggered by
Lessee as a result of an actual or proposed change in use, change in intensity
of use, or modification to the Premises then, and in that event, Lessee shall be
fully responsible for the cost thereof, and Lessee shall not have any right to
terminate this Lease.

     2.4    ACKNOWLEDGEMENTS. Lessee acknowledges that: (a) it has been advised
by Lessor and/or Brokers to satisfy itself with respect to the condition of the
Premises (including but not limited to the electrical, HVAC and fire sprinkler
systems, security, environmental aspects, and compliance with Applicable
Requirements and the Americans with Disabilities Act), and their suitability for
Lessee's intended use, (b) Lessee has made such investigation as it deems
necessary with reference to such matters and assumes all responsibility therefor
as the same relate to its occupancy of the Premises, and (c) neither lessor,
Lessor's agents, nor Brokers have made any oral or written representations or
warranties with respect to said matters other than as set forth in this Lease.
In addition, Lessor acknowledges that: (i) Brokers have made no representations,
promises: or warranties concerning Lessee's ability to honor the Lease or
suitability to occupy the Premises, and (ii) it is Lessor's sole responsibility
to investigate the financial capability and/or suitability of all proposed
tenants.

Security Deposit for the payment of any amount due Lessor or to reimburse or
compensate Lessor for any liability, expense, loss or damage which Lessor may
suffer or incur by reason thereof. If Lessor uses or applies all or any portion
of the Security

                                        9
<Page>

Deposit, Lessee shall within 10 days after written request therefor deposit
monies with Lessor sufficient to restore said Security Deposit to the full
amount required by this Lease. Should the Agreed Use be amended to accommodate a
material change in the business of Lessee or to accommodate a sublessee or
assignee, Lessor shall have the right to increase the Security Deposit to the
extent necessary, in Lessor's reasonable judgment, to account for any increased
wear and tear that the Premises may suffer as a result thereof. If a change in
control of Lessee occurs during this Lease and following such change the
financial condition of Lessee is, in Lessor's reasonable judgment, significantly
reduced, Lessee shall deposit such additional monies with Lessor as shall be
sufficient to cause the Security Deposit to be at a commercially reasonable
level based on such change in financial condition. Lessor shall not be required
to keep the Security Deposit separate from its general accounts. Within 14 days
after the expiration or termination of this Lease, if Lessor elects to apply the
Security Deposit only to unpaid Rent, and otherwise within 30 days after the
Premises have been vacated pursuant to Paragraph 7.4(c) below, Lessor shall
return that portion of the Security Deposit not used or applied by Lessor. No
part of the Security Deposit shall be considered to be held in trust, to bear
interest or to be prepayment for any monies to be paid by Lessee under this
Lease. See Paragraph 51 of Addendum No. 1.

6.   USE.

     6.1    USE. Lessee shall use and occupy the Premises only for the Agreed
Use, or any other legal use which is reasonably comparable thereto, and for no
other purpose. Lessee shall not use of permit the use of the Premises in a
manner that is unlawful, creates damage, waste or a nuisance, or that disturbs
occupants of or causes damage to neighboring premises or properties. Lessor
shall not unreasonably withhold or delay its consent to any written request for
a modification of the Agreed Use, so long as the same will not impair the
structural integrity of the improvements on the Premises or the mechanical or
electrical systems therein, and/or is not significantly more burdensome to the
Premises. If Lessor elects to withhold consent. Lessor shall within 7 days after
such request give written notification of same, which notice shall include an
explanation of Lessor's objections to the change in the Agreed.

     6.2    HAZARDOUS SUBSTANCES.

            (a)  REPORTABLE USES REQUIRE CONSENT. The term "Hazardous Substance"
as used in this Lease shall mean any product, substance, or waste whose
presence, use, manufacture, disposal, transportation, or release, either by
itself or in combination with other materials expected to be on the Premises, is
either: (i) potentially injurious to the public health, safety or welfare, the
environment or the Premises, (ii) regulated or monitored by any governmental
authority, or (iii) a basis for potential liability of Lessor to any
governmental agency or third party under any applicable statute or common law
theory. Hazardous Substances shall include, but not be limited to, hydrocarbons,
petroleum, gasoline, and/or crude oil or any products, by-products or fractions
thereof. Lessee shall not engage in any activity in or on the Premises which
constitutes a Reportable Use of Hazardous Substances without the express prior
written consent of Lessor and timely compliance (at Lessee's expense) with all
Applicable Requirements. "Reportable Use" shall mean (i) the installation or use
of any above or below ground storage tank, (ii) the generation, possession,
storage, use, transportation, or disposal of a Hazardous Substance that requires
a permit from, or with respect to which a report, notice,

<Page>

registration or business plan is required to be filed with, any governmental
authority, and/or (iii) the presence at the Premises of a Hazardous Substance
with respect to which any Applicable Requirements requires that a notice be
given to persons entering or occupying the Premises or neighboring properties.
Notwithstanding the foregoing, Lessee may use any ordinary and customary
materials reasonably required to be used in the normal course of the Agreed Use,
so long as such use is in compliance with all Applicable Requirements, is not a
Reportable Use, and does not expose the Premises or neighboring property to any
meaningful risk of contamination or damage or expose Lessor to any liability
therefor. In addition, Lessor may condition its consent to any Reportable Use
upon receiving such additional assurances as Lessor reasonably deems necessary
to protect itself, the public, the Premises and/or the environment against
damage, contamination, injury and/or liability, including, but not limited to,
the installation (and removal on or before Lease expiration or termination) of
protective modifications (such as concrete encasements) and/or increasing the
Security Deposit.

            (b)  DUTY TO INFORM LESSOR. If Lessee knows, or has reasonable cause
to believe, that a Hazardous Substance has come to be located in, on, under or
about the Premises, other than as previously consented to by Lessor, Lessee
shall immediately give written notice of such fact to Lessor, and provide Lessor
with a copy of any report, notice, claim or other documentation which it has
concerning the presence of such Hazardous Substance.

            (c)  LESSEE REMEDIATION. Lessee shall not cause or permit any
Hazardous Substance to be spilled or released in, on, under, or about the
Premises (including through the plumbing or sanitary sewer system) and shall
promptly, at Lessee's expense, take all investigatory and/or remedial action
reasonably recommended, whether or not formally ordered or required, for the
cleanup of any, contamination of, and for the maintenance, security and/or
monitoring of the Premises or neighboring properties, that was caused or
materially contributed to by Lessee, or pertaining to or involving any Hazardous
Substance brought onto the Premises during the term of this Lease, by or for
Lessee, or any third party.

            (d)  LESSEE INDEMNIFICATION. Lessee shall indemnify, defend and hold
Lessor, its agents, employees, lenders and ground lessor, if any, harmless from
and against any and all loss of rents and/or damages, liabilities, judgments,
claims, expenses, penalties, and attorneys' and consultants' fees arising out of
or involving any Hazardous Substance brought onto the Premises by or for Lessee,
or any third party (provided, however, that Lessee shall have no liability under
this Lease with respect to underground migration of any Hazardous Substance
under the Premises from areas outside of the Project). Lessee's obligations
shall include, but not be limited to, the effects of any contamination or injury
to person, property or the environment created or suffered by Lessee, and the
cost of investigation, removal, remediation, restoration and/or abatement, and
shall survive the expiration or termination of this Lease. No termination,
cancellation or release agreement entered into by Lessor and Lessee shall
release Lessee from its obligations under this Lease with respect to Hazardous
Substances, unless specifically so agreed by Lessor in writing at the time of
such agreement.

            (e)  LESSOR INDEMNIFICATION. Except as is disclosed to Lessee in the
last sentence of this paragraph, Lessor represents and warrants to Lessee that
as of the date hereof, Lessor has no actual knowledge of the presence of
Hazardous Substances at the Premises, and that Lessor has not received any
written notice of non-compliance with governmental regulations

                                       11
<Page>

from any governmental authority with respect to Hazardous Substances. Lessor
shall indemnify, protect, defend and hold Lessee and Lessee's officers,
directors, shareholders, employees, agents and sublessees harmless from and
against any and all damages, liabilities, judgments, costs, claims, liens,
expenses, penalties, loss of permits and reasonable attorneys' and consultants'
fees arising out of or involving: (i) any breach by Lessor of the foregoing
representation and warranty; and/or (ii) any Hazardous Substances now existing
or brought onto the Premises by or for Lessor or by anyone under Lessor's
control, except with respect to the lead referenced in the last sentence of this
paragraph. Lessee understands and acknowledges that Lessor has disclosed to
Lessee that certain steel columns in the Premises contain lead, and that Lessor
at Lessor's expense shall encapsulate the lead by painting the columns. Should
Lessee desire that the lead be encapsulated by a method other than painting,
which method does not violate Applicable Requirements and protects the health
and safety of persons in the Premises, Lessee shall bear the cost of such
alternative method.

            (f)  INVESTIGATIONS AND REMEDIATIONS. Lessor shall retain the
responsibility and pay for any investigations or remediation measures required
by governmental entities having jurisdiction with respect to the existence of
Hazardous Substances on the Premises prior to the Start Date, unless such
remediation measure is required as a result of Lessee's use (including
"Alterations", as defined in paragraph 7.3(a) below) of the Premises, in which
event Lessee shall be responsible for such payment. Lessee shall cooperate fully
in any such activities at the request of Lessor, including allowing Lessor and
Lessor's agents to have reasonable access to the Premises at reasonable times in
order to carry out Lessor's investigative and remedial responsibilities.

            (g)  LESSOR TERMINATION OPTION. If a Hazardous Substance Condition
(see Paragraph 9.1(e)) occurs during the term of this Lease, unless Lessee is
legally responsible therefor (in which case Lessee shall make the investigation
and remediation thereof required by the Applicable Requirements and this Lease
shall continue in full force and effect, but subject to Lessor's rights under
Paragraph 6.2(d) and Paragraph 13), Lessor may, at Lessor's option, either (i)
investigate and remediate such Hazardous Substance Condition, if required, as
soon as reasonably possible at Lessor's expense, in which event this Lease shall
continue in full force and effect, or (ii) if the estimated cost to remediate
such condition exceeds 12 times the then monthly Base Rent or $100,000,
whichever is greater, give written notice to Lessee, within 30 days after
receipt by Lessor of knowledge of the occurrence of such Hazardous Substance
Condition, of Lessor's desire to terminate this Lease as of the date 60 days
following the date of such notice. In the event Lessor elects to give a
termination notice, Lessee may, within 10 days thereafter, give written notice
to Lessor of Lessee's commitment to pay the amount by which the cost of the
remediation of such Hazardous Substance Condition exceeds an amount equal to 12
times the then monthly Base Rent or $100,000, whichever is greater. Lessee shall
provide Lessor with said funds or satisfactory assurance thereof within 30 days
following such commitment. In such event, this Lease shall continue in full
force and effect, and Lessor shall proceed to make such remediation as soon as
reasonably possible after the required funds are available. If Lessee does not
give such notice and provide the required funds or assurance thereof within the
time provided, this Lease shall terminate as of the dale specified in Lessor's
notice of termination.

     6.3    LESSEE'S COMPLIANCE WITH APPLICABLE REQUIREMENTS. Except as
otherwise provided in this Lease, Lessee shall, at Lessee's sole expense, fully,
diligently and in a timely manner, materially comply with all Applicable
Requirements, the requirements of any applicable fire insurance underwriter or
rating bureau, and the recommendations of Lessor's engineers and/or consultants
which relate in any manner to the Premises, without regard whether said
requirements are now in effect or become effective after the Start Date. Lessee
shall, within 10 days after receipt of Lessor's written request, provide Lessor
with copies of all permits and other documents, and other information evidencing
Lessee's compliance with any Applicable Requirements specified by Lessor, and
shall immediately upon receipt, notify Lessor in writing (with copies of any
documents involved) of any threatened or actual claim, notice, citation,
warning, complaint or report pertaining to or involving the failure of Lessee or
the Premises to comply with any Applicable Requirements.

     6.4    INSPECTION; COMPLIANCE. Lessor and Lessor's "Lender" (as defined in
Paragraph 30) and consultants shall have the right to enter into Premises at any
time, in the case of an emergency, and otherwise at reasonable times, on
reasonable advance notice, for the purpose of inspecting the condition of the
Premises and for verifying compliance by Lessee with this Lease. The cost of any
such inspections shall be paid by Lessor, unless a violation of Applicable
Requirements, or a contamination is found to exist or be imminent, or the
inspection is requested or ordered by a governmental authority. In such case,
Lessee shall upon request reimburse Lessor for the cost of such inspection, so
long as such inspection is reasonably related to the violation or contamination
and such violation or contamination was caused by Lessee or Lessee's employees,
agents or invitees.

of the Premises), including, but not limited to, all equipment or facilities,
such as plumbing, HVAC equipment, electrical facilities, boilers, pressure
vessels, fixtures, interior walls, interior surfaces of exterior walls,
ceilings, floors, windows, doors, plate glass, and skylights but excluding any
items which are the responsibility of Lessor pursuant to Paragraph 7.2. Lessee,

perform good maintenance practices, specifically including the procurement and
maintenance of the service contracts required by Paragraph 7.1(b) below,
Lessee's obligations shall include restorations, replacements or renewals when
necessary to keep the Premises and all improvements thereon or a part thereof in
good order, condition and state of repair.

                                       13
<Page>

            (b)  SERVICE CONTRACTS. Lessee shall, at Lessee's sole expense,

clarifiers, and (iv) any other equipment, if reasonably required by Lessor.
However. Lessor reserves the right, upon notice to Lessee, to procure and
maintain any or all of such service contracts, and if Lessor so elects, Lessee
shall reimburse Lessor, upon demand, for the cost thereof, except to the extent
that the amounts charged by Lessor to Losses exceed the generally prevailing
costs of such service contracts.

            (c)  FAILURE TO PERFORM. If Lessee fails to perform Lessee's
obligations under this Paragraph 7.1, Lessor may enter upon the premises after
10 days' prior written notice to Lessee (except in the case of an emergency, in

behalf, and put the Premises in good order, condition and repair, and Lessee
shall promptly reimburse Lessor for the cost thereof.

            (d)  REPLACEMENT. Subject to Lessee's indemnification of Lessor as
set forth in Paragraph 6.7 below, and without relieving Lessee of liability
resulting from Lessee's failure to exercise and perform good maintenance

than at a cost which is in excess of 50% of the cost of replacing such item,
then such item shall be replaced by Lessor, and the cost thereof shall be
prorated between the Parties and Lessee shall only be obligated to pay, each
month during the remainder of the term of this Lease, on the date on which Base
Rent is due, an amount equal to the product of multiplying the cost of such
replacement by a fraction, the numerator of which is one, and the denominator of
which is 144 (i.e. 1/144th of the cost per month). Lessee shall pay interest on
the unamortized balance at a rate that is commercially reasonable in the
judgment of Lessor's accountants. Lessee may, however, prepay its obligation at

hereafter in effect to the extent it is inconsistent with the terms of this
Lease. Lessee shall be responsible for the repair or replacement of the
foregoing to the extent not covered by Lessor's insurance, if the need for the
repair or replacement is due to damage caused by Losses or Lessee's employees,
agents or invitees. Lessor shall keep in good order, condition and repair the
foundations, exterior walls, structural condition of interior bearing walls and
exterior roof, without reimbursement from Lessee, unless the need for repair or
replacement is caused by acts or omissions of Lessee or its employees, agents or

security and fire protection systems, communication systems, lighting fixtures,
HVAC equipment, plumbing, and fencing in or on the Premises. The term "TRADE
FIXTURES" shall mean Lessee's machinery and equipment that can be removed
without doing material damage to the Premises and are not in any way paid for by

not yet owned by Lessor pursuant to Paragraph 7.4(a).

            (b)  CONSENT. Lessee shall not make any Alterations or Utility
Installations to the Premises without Lessor's prior written consent. Lessee
may, however, make non-structural Utility Installations to the Interior of the
Premises (excluding the roof) without such consent but upon notice to Lessor, as
long as they are not visible from the outside, do not involve puncturing,
relocating or removing the roof or any existing wails, and the cumulative cost
thereof during this Lease as extended does not exceed a sum equal to 3 month's
Base Rent in the aggregate or a sum equal to one month's Base Rent in any one
year. Notwithstanding the foregoing, Lessee shall not make or permit any roof
penetrations and/or install anything on the roof without the prior written
approval of Lessor. Lessor may, as a precondition to granting such approval,
require Lessee to utilize a contractor chosen and/or approved by Lessor. Any
Alterations or Utility Installations that Lessee shall desire to make and which
require the consent of the Lessor shall be presented to Lessor in written form
with detailed plans. Consent shall be deemed conditioned upon Lessee's: (1)
acquiring all applicable governmental permits, (it) furnishing Lessor with
copies of both the permits and the plans and specifications prior to
commencement of the work, and (iii) compliance with all conditions of said
permits and other Applicable Requirements in a prompt and expeditious manner.
Any Alterations or Utility Installations shall be performed in a workmanlike
manner with good and sufficient materials. Lessee shall promptly upon completion
furnish Lessor with as-built plans and specifications. For work which costs an
amount in excess of one month's Base Rent, Lessor may condition its consent upon
Lessee providing a lien and completion bond in an amount equal to 150% of the
estimated cost of such Alteration or Utility Installation and/or upon Lessee's
posting an additional Security Deposit with Lessor.

            (c)  INDEMNIFICATION. Lessee shall pay, when due, all claims for
labor or materials furnished or alleged to have been furnished to or for Lessee
at or for use on the Premises, which claims are or may be secured by any
mechanic's or materialman's lien against the Premises or any interest therein.
Lessee shall give Lessor not less than 10 days notice prior to the commencement
of any work in, on or about the Premises, and Lessor shall have the right to
post notices of non-responsibility. If Lessee shall contest the validity of any
such lien, claim or demand. then Lessee shall, at its sole expense defend and
protect itself, Lessor and the Premises against the same and shall pay and
satisfy any such adverse judgment that may be rendered thereon before the
enforcement thereof. If Lessor shall require, Lessee shall furnish a surety bond
in an amount equal to 150% of the amount of such contested lien, claim or
demand, indemnifying Lessor against liability for the same. If Lessor elects to
participate in any such action, Lessee shall pay Lessor's attorneys' fees and
costs.

     7.4    OWNERSHIP; REMOVAL; SURRENDER; AND RESTORATION.

            (a)  OWNERSHIP. Subject to Lessor's right to require removal or
elect ownership as hereinafter provided, all Alterations and Utility
Installations made by Lessee shall be the property of Lessee, but considered a
part of the Premises. Lessor may, at any time, elect in writing to be the owner
of all or any specified part of the Lessee Owned Alterations and Utility
Installations. Unless otherwise instructed per paragraph 7.4(b) hereof, all
Lessee Owned Alterations and Utility Installations shall, at the expiration or
termination of this Lease, become the property of Lessor and be surrendered by
Lessee with the Premises.

            (b)  REMOVAL. By delivery to Lessee of written notice from Lessor
not earlier than 90 and not later than 30 days prior to the end of the term of
this Lease, Lessor may require that any or all Lessee Owned Iterations or
Utility Installations be removed by the expiration or termination of this Lease.
Lessor may require the removal at any time of all or any part o any Lessee Owned
Alterations or Utility Installations made without the required consent.
Notwithstanding the foregoing, however, with respect to all alterations and
improvements to the Premises desired by Lessee and consented to in writing by
Lessor, Lessor shall not have the right to require Lessee to remove them at
Lease expiration unless Lessor reserves such right at the time Lessor consents
to the installation of such alterations or improvements (and provided that
Lessee has indicated in its written request for consent that Lessor must reserve
such removal right or else Lessor's removal right shall be deemed waived). Under
no circumstances shall Lessee have the right to remove from the Premises at any
time any improvements, Alterations or Utility Installations now or hereafter
existing in the Premises, nor any Trade Fixtures that have been attached to the
Premises in any manner, regardless of the method of attachment to the Premises,
and all of such improvements, Alterations, Utility. Installations and attached
Trade Fixtures (including without limitation cabinets, desks, workstations,
decorative lighting fixtures and other built-in furniture or fixtures that are
bolted, screwed, glued or otherwise attached to floors or interior or exterior
walls or other portions of the Premises) shall be surrendered to Lessor at the
expiration or earlier termination of the Lease in their original condition,
ordinary wear and tear excepted. Notwithstanding the foregoing to the contrary,
however, Lessee shall have the right to remove from the Premises any Trade
Fixtures paid for by Lessee without using the T.I. Allowance, so long as Lessee
at Lessee's expense repairs my damage to the Premises caused as a result
thereby.

            (c)  SURRENDER; RESTORATION. Lessee shall surrender the Premises by
the Expiration Date or any earlier termination date, with all )f the
improvements, parts and surfaces thereof broom clean and free of debris, and in
good operating order, condition and state of repair, ordinary wear and tear
excepted. "Ordinary wear and tear" shall not include any damage or deterioration
that would have been prevented by good maintenance practice. Notwithstanding the
foregoing, if this Lease is for 12 months or less, then Lessee shall surrender
the Premises in the same condition as delivered to Lessee on the Start Date with
NO allowance for ordinary wear and tear. Lessee shall repair any damage
occasioned by the installation, maintenance or removal of Trade Fixtures, Lessee
owned Alterations and/or Utility Installations, furnishings, and equipment as
well as the removal of any storage tank installed by or for Lessee. Lessee shall
also completely remove from the Premises any and all Hazardous Substances
brought onto the Premises by or for Lessee, or any thin: party (except Hazardous
Substances which were deposited via underground migration from areas outside of
the Project) even if such removal

                                       16
<Page>

would require Lessee to perform or pay for work that exceeds statutory
requirements. Trade Fixtures shall remain the property of Lessee and shall be
removed by Lessee. The failure by Lessee to timely vacate the Premises pursuant
to this Paragraph 7.4(c) without the express written consent of Lessor shall
constitute a holdover under the provisions of Paragraph 26 below.

less than $2,000,000 per occurrence with an annual aggregate of not less than
$5,000,000, are "Additional Insured-Managers or Lessors of Premises Endorsement"
and contain the "Amendment of the Pollution Exclusion Endorsement" for damage
caused by heat, smoke or fumes from a hostile fire. The policy shall not contain
any intra-insured exclusions as between insured persons or organizations, but
shall include coverage liability assumed under this Lease as an "insured
contract" for the performance of Lessee's indemnity obligations under this
Lease. The limits of said insurance shall not, however, limit the liability of
Lessee of any obligation hereunder. All insurance carried by Lessee shall be
primary to and not contributory with any similar insurance carried by Lessor,
whose insurance shall be considered excess insurance only.

            (b)  CARRIED BY LESSOR. Lessor shall maintain liability insurance as
described in Paragraph 8.2(a), in addition to, and not in lieu of, the insurance
required to, be maintained by Lessee. Lessee shall not be named as an additional

clause, and the amount of coverage shall be adjusted annually to reflect the
projected Rent otherwise payable by Lessee, for the next 12 month period.

            (c)  ADJACENT PREMISES. Lessee shall pay for any increase in the
premiums for the property insurance of the Building and for the Common Areas or
other buildings in the Project if said increase is caused by Lessee's acts,
omissions, use or occupancy of the Premises, other than me permitted in
Paragraph 1.8 above.

            (d)  LESSEE'S IMPROVEMENTS. Since Lessor is the Insuring Party,
Lessor shall not be required to insure Lessee Owned Alterations and Utility
Installations unless the item in question has become the property of Lessor
under the terms of this Lease.

     8.4    LESSEE'S PROPERTY; BUSINESS INTERRUPTION INSURANCE.

            (a)  PROPERTY DAMAGE. Lessee shall obtain and maintain insurance
coverage on all of Lessee's personal property, Trade Fixtures, and Lessee Owned
Alterations and Utility Installations. Such insurance shall be full replacement
cost coverage with a deductible of not to exceed $1,000 per occurrence. The
proceeds from any such insurance shall be used by Lessee for the replacement of
personal property, Trade Fixtures and Lessee Owned Alterations and Utility
Installations. Lessee shall provide Lessor with written evidence that such
insurance is in force.

            (b)  BUSINESS INTERRUPTION. Lessee shall obtain and maintain loss of
income and extra expense insurance in amounts as will reimburse Lessee for
direct or indirect loss of earnings attributable to all perils commonly insured
against by prudent lessees in the business of Lessee or attributable to
prevention of access to the Premises as a result of such perils.

            (c)  NO REPRESENTATION OF ADEQUATE COVERAGE. Lessor makes no
representation that the limits or fortes of coverage of insurance specified
herein are adequate to cover Lessee's property, business operations or
obligations under this Lease.

     8.5    INSURANCE POLICIES. Insurance required herein shall be by companies
duly licensed or admitted to transact business in the state where the Premises
are located, and maintaining during the policy term a "GENERAL POLICYHOLDERS

Insurance Guide", or such other rating as may be

                                       18
<Page>

required by a Lender. Lessee shall not do or permit to be done anything which
invalidates the required insurance policies. Lessee shall, prior to the Start
Date, deliver to Lessor certified copies of policies of such Insurance or
certificates evidencing the existence and amounts of the required Insurance. No
such policy shall be cancelable or subject to modification except after 30 days
prior written notice to Lessor. Lessee shall, at least 30 days prior to the
expiration of such policies, furnish Lessor with evidence of renewals or
"insurance binders" evidencing renewal thereof, or Lessor may order such
insurance and charge the cost thereof to Lessee, which amount shall be payable
by Lessee to Lessor upon demand. Such policies shall be for a term of al least
one year, or the length of the remaining term of this Lease, whichever is less.
If either Party shall fail to procure and maintain the insurance required to be
carried by it, the other Party may, but shall not be required to, procure and
maintain the same.

     8.6    WAIVER OF SUBROGATION. Without affecting any other rights or
remedies, Lessee and Lessor each hereby release and relieve the other, and waive
their entire right to recover damages against the other, for loss of or damage
to its property arising out of or incident to the perils required to be insured
against herein. The effect of such releases and waivers is not limited by the
amount of insurance carried or required, or by any deductibles applicable
hereto. The Parties agree to have their respective property damage insurance
carriers waive any right to subrogation that such companies may have against
Lessor or Lessee, as the case may be, so long as the insurance is not
invalidated thereby.

     8.7.   INDEMNITY. Except for Lessor's gross negligence or willful
     misconduct, Lessee shall indemnify, protect, defend and hold harmless the
     Premises, Lessor and its agents, Lessor's master or ground lessor, partners
     and Lenders, from and against any and all claims, loss of rents and/or
     damages, liens, judgments, penalties, attorneys' and consultants' fees,
     expenses and/or liabilities arising out of, involving or in connection
     with, the use and/or occupancy of the Premises by Lessee. If any action or
     proceeding is brought against Lessor by reason of any of the foregoing
     matters, Lessee shall upon notice defend the same at Lessee's expense by
     counsel reasonably satisfactory to Lessor and Lessor shall cooperate with
     Lessee in such defense. Lessor need not have first paid any such claim in
     order to be defended or indemnified. Lessor shall indemnify, protect,
     defend and hold harmless Lessee and it's members, officers, directors,
     shareholders and employees from and against any and all claims, damages,
     costs, liens, judgments, penalties, loss of permits, attorney's and
     consultant's fees, expenses and liabilities arising out of, involving, or
     dealing with: (i) the gross negligence or willful misconduct of Lessors or
     Lessor's employees or agents, and/or Lessor's breach of its express
     warranties set forth in this Lease, or (ii) Lessor's material default under
     any of its obligations under this Lease, following written notice and the
     expiration of any applicable cure period as provided in Paragraph 13.6(a)
     of the Lease. In case any action or proceeding shall be brought against
     Lessee by reason of any of the foregoing matters, Lessor upon notice from
     Lessee shall defend the same at Lessor's expense by counsel reasonably
     satisfactory to Lessee and Lessee shall cooperate with Lessor in such
     defense. However, the indemnification obligations of Lessor under this
     Paragraph 8.7 shall not apply or extend to any injury to or interference
     with Lessee's business or to Lessee's consequential damages.

30 days from the date of the damage or destruction as to whether or not the
damage is Partial or Total.

            (b)  "PREMISES TOTAL DESTRUCTION" shall mean damage or destruction
to the improvements on the Premises, other than Lessee Owned Alterations and
Utility Installations and Trade Fixtures, which cannot reasonably be repaired in
3 months or less from the date of the damage or destruction and/or the cost

in writing within 30 days from the date of the damage or destruction as to
whether or not the damage is Partial or Total.

            (c)  "INSURED LOSS" shall mean damage or destruction to improvements

basis for that purpose. Notwithstanding the foregoing, if the required insurance
was not in force or the insurance proceeds are not sufficient to effect such
repair, the Insuring Party shall promptly contribute the shortage in proceeds as
and when required to complete said repairs. In the event, however, such shortage
was due to the fact that, by reason of the unique nature of the improvements,
full replacement cost insurance coverage was not commercially reasonable and
available, Lessor shall have no obligation to pay for the shortage in insurance
proceeds or to fully restore the unique aspects of the Premises unless Lessee
provides Lessor with the funds to cover same, or adequate assurance thereof,

Lessor's expense, in which event this Lease shall continue in full force and
effect, or (i1) terminate this Lease by giving written notice to Lessee within
30 days after receipt by Lessor of knowledge of the occurrence of such damage.
Such termination shall be effective 60 days following the date of such notice.

satisfactory assurance thereof within 30 days after making such commitment. In
such event this Lease shall continue in full force and effect, and Lessor shall

funds are available. If Lessee does not make the required commitment, this Lease
shall terminate as of the date specified in the termination notice.

this Lease there is damage for which the cost to repair exceeds one month's Base

<Page>

only apply if Lessee did not cause the damage) effective 60 thirty (30) days
following the date of occurrence of such damage by giving a written termination
notice to Lessee within 30 days after the date of occurrence of such damage.

to extend this Lease or to purchase the Premises. then Lessee may preserve this
Lease by, (a) exercising such option and (b) providing Lessor with any shortage
in insurance proceeds (or adequate assurance thereof) needed to make the repairs
on or before the earlier of (1) the date which is 10 days after Lessee's receipt
of Lessor's written notice purporting to terminate this Lease, or (ii) the day
prior to the date upon which such option expires. If Lessee duly exercises such
option during such period and provides Lessor with funds (or adequate assurance
thereof) to cover any shortage in insurance proceeds, ;Lessor shall, at Lessor's
commercially reasonable expense, repair such damage as soon as reasonably
possible and this Lease shall continue in full force and effect. If Lessee fails
to exercise such option and provide such funds or assurance during such period,
then this Lease shall terminate on the date specified in the termination notice
and Lessee's option shall be extinguished.

     9.6    ABATEMENT OF RENT; LESSEE'S REMEDIES.

            (a)  ABATEMENT. In the event of Premises Partial Damage or Premises

not to exceed the proceeds received from the Rental Value insurance. All other
obligations of Lessee hereunder shall be performed by Lessee, and Lessor shall
have no liability for any such damage, destruction, remediation, repair or
restoration except as provided herein.

            (b)  REMEDIES. If Lessor shall be obligated to repair or restore the
Premises and does not commence, in a substantial and meaningful way, such repair
or restoration within 00 60 days after such obligation shall accrue, Lessee may,
at any time prior to the commencement of such repair or restoration, give
written notice to Lessor and to any Lenders of which Lessee has actual notice,
of Lessee's election to terminate this Lease on a date not less than 60 days
following the giving of such notice. If Lessee gives such notice and such repair
or restoration is not commenced within 30 days hereafter, this Lease shall
terminate as of the date specified in said notice. If the repair or restoration
is commenced within such 30 days, this Lease shall continue in full force and
effect. "Commence" shall mean the beginning of the actual work on the Premises.

within sixty (60) days after the date of any damage or destruction, Lessor shall
notify Lessee of the estimated time, as reasonably estimated by licensed general
contractor selected by Lessor, to complete the repairs and restoration of the
Premises and whether the damage or destruction is an Insured Loss. If Lessor
fails to so notify Lessee within such sixty (60) day period, Lessee may
terminate this Lease effective as of the date of such damage or destruction by
delivering written notice to Lessor of Lessee's termination election no later
than ten (10) days from the expiration of such sixty (60) day period; provided,
however, that should Lessee so elect to terminate the Lease then Lessor shall
then have the right to advise Lessee of the information required to be given
Lessee by the first sentence of this paragraph within five (5) days following
Lessor's receipt of Lessee's termination notice, which shall thereby nullify
Lessee's termination notice. If Lessor notifies Lessee that the estimated time
to, complete the repairs or restoration

                                       22
<Page>

will exceed two hundred ten (210) days from the date of such damage or
destruction, Lessee may terminate this Lease effective as of the date of such
damage or destruction by delivering written notice thereof to Lessor within ten
(10) days after receipt of Lessor's notice. If the Lease is not terminated as
provided above, and the repairs and restoration are not substantially completed
within two hundred ten (210) days after the date of damage or destruction,
Lessee may deliver written notice to Lessor stating that if the repairs and
restoration are not substantially completed within thirty (30) days thereafter,
Lessee will terminate the Lease. If the repairs and restoration are not
substantially completed within thirty (30) days after the Lessee delivers such
notice to Lessor, Lessee may terminate the Lease effective as of the date of
such damage or destruction by delivering written notice thereof to Lessor within
ten (10) days after the expiration of such thirty (30) day period; if the
repairs are substantially completed within such thirty (30) day period, Lessee
shall not have the right to terminate the Lease.

     9.7    TERMINATION; ADVANCE PAYMENTS. Upon termination of this Lease
pursuant to Paragraph 6.2(g) or Paragraph 9, an equitable adjustment shall be
made concerning advance Base Rent and any other advance payments made by Lessee

include Real Property Taxes specified in the tax assessor's records and work
sheets as being caused by additional improvements placed upon the Project by
other lessees or by Lessor for the exclusive enjoyment of such other lessees.

commonly metered utilities, or that Lessee is generating such a large volume of
trash as to require an increase in the size of the dumpster and/or an increase
in the number of times per month that the dumpster is emptied, then Lessor may
increase Lessee's Base Rent by an amount equal to such increased costs.

12.  ASSIGNMENT AND SUBLETTING.  See Paragraph 55 of Addendum No. 1.

provided, however, no sublease or assignment to an Affiliate shall release the
original Lessee named in this Lease from liability under this Lease. Lessee
shall immediately notify Lessor of any such assignment, purchase, transfer,
sublease, action or use, and of the name of the Affiliate, the portion of the
Premises subject to the transaction, and the commencement and expiration dates

                 (b)     Lessor may accept Rent or performance of Lessee's
obligations from any person other than Lessee pending approval or disapproval of
an assignment. Neither a delay in the approval or disapproval of such assignment
nor the acceptance of Rent or performance shall constitute a waiver or estoppel
of Lessor's right to exercise its remedies for Lessee's Default or Breach.

                 (c)     Lessor's consent to any assignment or subletting shall
not constitute a consent to any subsequent assignment or subletting.

may proceed directly against Lessee, any Guarantors or anyone else responsible

considering and processing said request. Lessee agrees to provide Lessor with
such other or additional information and/or documentation as may be reasonably
requested.

                 (f)     Any assignee of, or sublessee under, this Lease shall,
by reason of accepting such assignment or entering into such sublease, be deemed
to have assumed and agreed to conform and comply with each and every term,
covenant, condition and obligation herein to be observed or performed by Lessee
during the term of said assignment or sublease, other than such obligations as
are contrary to or inconsistent with provisions of an assignment or sublease to
which Lessor has specifically consented to in writing.

                 (g)     Lessor's consent to any assignment or subletting shall
not transfer to the assignee or sublessee any Option granted to the original

irrevocably authorizes and directs any such sublessee, upon receipt of a written
notice from Lessor stating that a Breach exists in the, performance of Lessee's
obligations under this Lease, to pay to Lessor all Rent due and to become due

shall pay all Rents to Lessor without any obligation or right to inquire as to
whether such Breach exists, notwithstanding any claim from Lessee to the
contrary.

                 (b)     In the event of a Breach by Lessee, Lessor may, at its
option, require sublessee to attorn to Lessor, in which event Lessor shall
undertake the obligations of the sublessor under such sublease from the time of
the exercise of said option to the expiration of such sublease; provided,
however, Lessor shall not be liable for any prepaid rents or security deposit
paid by such sublessee to such sublessor or for any prior Defaults or Breaches
of such sublessor.

                 (c)     Any matter requiring the consent of the sublessor under
a sublease shall also require the consent of Lessor.

                 (d)     No sublessee shall further assign or sublet all or any

within any applicable grace period:

                 (a)     The abandonment of the Premises; or the vacating of the
Premises without providing a commercially reasonable level of security, or where
the coverage of the property insurance described in Paragraph 8.3 is jeopardized
as a result thereof, or without providing reasonable assurances to minimize
potential vandalism.

                 (b)     The failure of Lessee to make any payment of Rent or
any Security Deposit required to be made by Lessee hereunder, whether to Lessor
or to a third party, when due, to provide reasonable evidence of insurance or
surety bond, or to fulfill any obligation under this Lease which endangers or
threatens life or property, where such failure continues for a period of 3
business days following written notice to Lessee.

                 (c)     The failure by Lessee to provide (i) reasonable written
evidence of compliance with Applicable Requirements, (ii) the service contracts,
(iii) the rescission of an unauthorized assignment or subletting, (iv) an
Estoppel Certificate, (v) a requested subordination, (vii) any document
requested under Paragraph 41 (easements), or (viii) any other documentation or
information which Lessor may reasonably require of Lessee under the terms of
this Lease, where any such failure continues for a period of 10 days following
written notice to Lessee.

                 (d)     A Default by Lessee as to the terms, covenants,
conditions or provisions of this Lease, or of the rules adopted under Paragraph
2.9 hereof, other than those described in subparagraphs 13.1(a), (b) or (c),
above, where such Default continues for a period of 30 days after written
notice; provided, however, that if the nature of Lessee's Default is such that
more than 30 days are reasonably required for its cure, then it shall not be
deemed to be a Breach if Lessee commences such cure within said 30 day period
and thereafter diligently prosecutes such cure to completion.

                 (e)     The occurrence of any of the following events: (1) the
making of any general arrangement or assignment for the benefit of creditors;
(ii) becoming a "debtor" as defined in 11 U.S.C. g 101 or any successor statute
thereto (unless, in the case of a petition filed against Lessee, the came is
dismissed within 60 days); (iii) the appointment of a trustee or receiver to
take possession of substantially all of Lessee's assets located at the Premises
or of Lessee's interest in this Lease, where possession is not restored to
Lessee within 30 days; or (iv) the attachment, execution or other judicial
seizure of substantially all of Lessee's assets located at the Premises or of
Lessee's interest in this Lease, where such seizure is not discharged within

                                       27
<Page>

30 days; provided, however, in the event that any provision of this subparagraph
(e) is contrary to any applicable law, such provision shall be of no force or
effect, and not affect the validity of the remaining provisions.

                 (f)     The discovery that any financial statement of Lessee or
of any Guarantor given to Lessor was materially false or misleading.

                 (g)     [DELETED]

     13.2   REMEDIES. If Lessee fails to perform any of its affirmative duties
or obligations within 10 days after written notice (or in case of an emergency,
without notice), Lessor may, at its option, perform such duty or obligation on
Lessee's behalf, including but not limited to the obtaining of reasonably
required bonds, insurance policies, or governmental licenses, permits or
approvals. The costs and expenses of any such performance by Lessor shall be due
and payable by Lessee upon receipt of invoice therefor. If any check given to
Lessor by Lessee shall not be honored by the bank upon which it is drawn,
Lessor, at its option, may require all future payments to be made by Lessee to
be by cashier's check. In the vent of a Breach, Lessor may, with or without
notice or demand, and without limiting Lessor in the exercise of any right or
remedy which Lessor may have by reason of such Breach;

                 (a)     Terminate Lessee's right to possession of the Premises
by any lawful means, in which case this Lease shall terminate and Lessee shall
immediately surrender possession to Lessor. In such event Lessor shall be
entitled to recover from Lessee: (i) the unpaid Rent which had been earned at
the time of termination; (ii) the worth at the time of award of the amount by
which the unpaid rent which would have been earned after termination until the
time of award exceeds the amount of such rental loss that the Lessee proves
could have been reasonably avoided; (iii) the worth at the time of award of the
amount by which the unpaid rent for the balance of the term after the time of
award exceeds the amount of such rental loss that the Lessee proves could be
reasonably avoided; and (iv) any other amount necessary to compensate Lessor for
all the detriment proximately caused by the Lessee's failure to perform its
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom, including but not limited to the cost of recovering
possession of the Premises, expenses of reletting, including necessary
renovation and alteration of the Premises, reasonable attorneys' fees, and that
portion of any leasing commission paid by Lessor in connection with this Lease
applicable to the unexpired term of this Lease. The worth at the time of award
of the amount referred to in provision (lit) of the immediately preceding
sentence shall be computed by discounting such amount al the discount rata of
the Federal Reserve Bank of the District within which the Premises are located
at the time of award plus one percent. Efforts by Lessor to mitigate damages
caused by Lessee's Breach of this lease shall not waive Lessor's right to
recover damages under Paragraph 12. If termination of this Lease is obtained
rough the provisional remedy of unlawful detainer, Lessor shall have the right
to recover in such proceeding any unpaid Rent and damages as are recoverable
therein, or lessor may reserve the right to recover all or any part thereof in a
separate suit. If a notice and grace period required under Paragraph 13.1 was
not previously given, a notice to pay rent or quit, or to perform or quit given
to Lessee under the unlawful detainer statute shall also constitute the notice
required by Paragraph 13.1. In such case, the applicable grace period required
by Paragraph 13.1 and the unlawful detainer statute shall run concurrently, and
the failure of Lessee to cure the Default

                                       28
<Page>

within the greater of the two such grace periods shall constitute both an
unlawful detainer and a Breach of this Lease entitling Lessor to the remedies
provided for in this Lease and/or by said statute.

                 (b)     Continue the Lease and Lessee's right to possession and
recover the Rent as it becomes due, in which event Lessee may sublet or assign,
subject only to reasonable limitations. Acts of maintenance, efforts to relet
and/or the appointment of a receiver to protect the Lessor's interests, shall
not constitute a termination of the Lessee's right to possession.

                 (c)     Pursue any other remedy now or hereafter available
under the laws or judicial decisions of the state wherein the Premises are
located. The expiration or termination of this Lease and/or the termination of
Lessee's right to possession shall not relieve Lessee from liability under any
indemnity provisions of this Lease as to matters occurring or accruing during
the term hereof or by reason of Lessee's occupancy of the Premises.

     13.3   INDUCEMENT RECAPTURE. Any agreement for free or abated rent or other
charges, or for the giving or paying by Lessor to or for Lessee of any cash or
other bonus, inducement or consideration for Lessee's entering into this Lease,
ail of which concessions are hereinafter referred to as "Inducement Provisions",
shall be deemed conditioned upon Lessee's full and faithful performance of all
of the terms, covenants and conditions of this Lease. Upon Breach of this Lease
by Lessee, any such Inducement Provision shall automatically be deemed deleted
from this Lease and of no further force or effect, and any rent, other charge,
bonus, inducement or consideration theretofore abated, given or paid by Lessor
under such an Inducement Provision shall be immediately due and payable by
Lessee to Lessor, notwithstanding any subsequent cure of said Breach by Lessee.
The acceptance by Lessor of rent or the cure of the Breach which initiated the
operation of this paragraph shall not be deemed a waiver by Lessor of the
provisions of this paragraph unless specifically so stated in writing by Lessor
at the time of such acceptance.

     13.4   LATE CHARGES. Lessee hereby acknowledges that late payment by Lessee
of Rent will cause Lessor to incur costs not contemplated by this Lease, the
exact amount of which will be extremely difficult to ascertain. Such costs
include, but are not limited to, processing and accounting charges, and late
charges which may be imposed upon Lessor by any Lender. Accordingly, if any Rent
shall not be received by Lessor within 5 days after such amount shall be due,
then, without any requirement for notice to Lessee other than once per calendar
year, Lessee shall pay to Lessor a one-time late charge equal to 5% of each such
overdue amount or $100, whichever is greater. The parties hereby agree that such
late charge represents a fair and reasonable estimate of the costs Lessor will
incur by reason of such late payment. Acceptance of such late charge by Lessor
shall in no event constitute a waiver of Lessee's Default or Breach with respect
to such overdue amount, nor prevent the exercise of any of the other rights and
remedies granted hereunder. In the event that a late charge is payable
hereunder, whether or not collected, for 3 consecutive installments of Base
Rent, then notwithstanding any provision of this Lease to the contrary, Base
Rent shall, at Lessor's option, become due and payable quarterly in advance.

     13.5   INTEREST. Any monetary payment due Lessor hereunder, other than late
charges, not received by Lessor, when due as to scheduled payments (such as Base
Rent) or within 30

                                       29
<Page>

days following the date on which it was due for non-scheduled payment, shall
bear interest from the date when due, as to scheduled payments, or the 31st day
after it was due as to non-scheduled payments. The Interest ("Interest") charged
shall be equal to the prime rate reported in the Wall Street Journal as
published closest prior to the date when due plus 4%, but shall not exceed the
maximum rate allowed by law. Interest is payable in addition to the potential
late charge provided for in Paragraph 13.4.

     13.6   BREACH BY LESSOR.

                 (a)     NOTICE OF BREACH. Lessor shall not be deemed in breach
of this Lease unless Lessor tails within a reasonable time to perform an
obligation required to be performed by Lessor. For purposes of this Paragraph, a
reasonable time shall in no event be less than 30 days after receipt by Lessor,
and any Lender whose name and address shall have been furnished Lessee in
writing for such purpose, of written notice specifying wherein such obligation
of Lessor has not been performed; provided, however, that if the nature of
Lessor's obligation is such that more than 30 days are reasonably required for
its performance, then Lessor shall not be in breach if performance is commenced
within such 30 day period and thereafter diligently pursued to completion.

                 (b)     [DELETED]

14.  CONDEMNATION. If the Premises or any portion thereof are taken under the
power of eminent domain or sold under the threat of the exercise of said power
(collectively "Condemnation"), this Lease shall terminate as to the part taken
as of the date the condemning authority takes title or possession. whichever

of Lessee's Reserved Parking Spaces, is taken by Condemnation, Lessee may, at
Lessee's option, to be exercised in writing within 10 days after Lessor shall
have given Lessee written notice of such taking (or in the absence of such
notice, within 10 days after the condemning authority shall have taken
possession) terminate this Lease as of the date the condemning authority takes
such possession. If Lessee does not terminate this Lease in accordance with the
foregoing, this Lease shall remain in full force and effect as to the portion of
the Premises remaining, except that the Base Rent shall be reduced in proportion
to the reduction in utility of the Premises caused by such Condemnation.
Condemnation awards and/or payments shall be the property of Lessor, whether
such award shall be made as compensation for diminution in value of the
leasehold, the value of the part taken, or for severance damages; provided,
however, that Lessee shall be entitled to any compensation for Lessee's
relocation expenses, loss of business goodwill and/or Trade Fixtures, without
regard to whether or not this Lease is terminated pursuant to the provisions of
this Paragraph. All Alterations and Utility Installations made to the Premises
by Lessee, for purposes of Condemnation only, shall be considered the property
of the Lessee and Lessee shall be entitled to any and all compensation which is
payable therefor. In the event that this Lease is not terminates by reason of

25.  DISCLOSURES REGARDING THE NATURE OF A REAL ESTATE AGENCY RELATIONSHIP.

     (a)    When entering into a discussion with a real estate agent regarding a
real estate transaction, a Lessor or Lessee should from the outset understand
what type of agency

                                       33
<Page>

relationship or representation it has with the agent or agents in the
transaction. Lessor and Lessee acknowledge being advised by the Brokers in this
transaction, as follows:

                 (i)     LESSOR'S AGENT. A Lessor's agent under a listing
agreement with the Lessor acts as the agent for the Lessor only. A Lessor's
agent or subagent has the following affirmative obligations: TO THE LESSOR: A
fiduciary duty of utmost care, integrity, honesty, and loyalty in dealings with
the Lessor. TO THE LESSEE AND THE LESSOR: (a) Diligent exercise of reasonable
skills and care in performance of the agent's duties. (b) A duty of honest and
fair dealing and good faith. (c) A duty to disclose all facts known to the agent
materially affecting the value or desirability of the property that are not
known to, or within the diligent attention and observation of, the Parties. An
agent is not obligated to reveal to either Party any confidential information
obtained from the other Party which does not involve the affirmative duties set
forth above.

                 (ii)    LESSEE'S AGENT. An agent can agree to act as agent for
the Lessee only. In these situations, the agent is not the Lessor's agent, even
if by agreement the agent may receive compensation for services rendered, either
in full or in part from the Lessor. An agent acting only for , Lessee has the
following affirmative obligations. TO THE LESSEE: A fiduciary duty of utmost
care, integrity, honesty, and loyalty in dealings with the Lessee. TO THE LESSEE
AND THE LESSOR: (a) Diligent exercise of reasonable skills d care in performance
of the agent's duties. (b) A duty of honest and fair dealing and good faith. (c)
A duty to disclose all facts known to the agent materially affecting the value
or desirability of the property that are not known to, or within the diligent
attention and observation of, the Parties. An agent is not obligated to reveal
to either Party any confidential information obtained from the other Party which
does not involve the affirmative duties set forth above.

                 (iii)   AGENT REPRESENTING BOTH LESSOR AND LESSEE. A real
estate agent, either acting directly or through one or more associate licenses,
can legally be the agent of both the Lessor and the Lessee in a transaction, but
only with the knowledge and consent of both the Lessor and the Lessee. In a dual
agency situation, the agent has the following affirmative obligations to both
the Lessor and the Lessee: (a) A fiduciary duty of utmost care integrity,
honesty and loyalty in the dealings with either Lessor or the Lessee. (b) Other
duties to the Lessor and the Lessee as stated above in subparagraphs (i) or
(ii). In representing both Lessor and Lessee, the agent may not without the
express permission of the respective Party, disclose to the other Party that the
Lessor will accept rent in an amount less than that indicated in the listing or
that the Lessee is willing to pay a higher rent than the offered. The above
duties of the agent in a real estate transaction do not relieve a Lessor or
Lessee from the responsibility to protect their own interests. Lessor and Lessee
should carefully read all; agreements to assure that they adequately express
their understanding of the transaction. A real estate agent is a person
qualified to advise about real estate. If legal or tax advice is desired,
consult a competent professional.

     (b)    Brokers have no responsibility with respect to any default or breach
hereof by either Party the liability (including court costs and attorneys' fee),
of any Broker with respect to any breach of duty, error or omission relating to
this Lease shall not exceed the fee received by such Broker pursuant to this
Lease; provided, however, that the foregoing limitation on each

                                       34
<Page>

Broker's liability shall not be applicable to any gross negligence or willful
misconduct of such Broker.

     (c)    Buyer and Seller agree to identify to brokers as "Confidential" any
communication or information given Brokers that is considered by such Party to
be confidential.

26.  NO RIGHT TO HOLDOVER. Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or termination of this Lease.
In the event that Lessee holds over, then the Base Rent shall be increased to
150% of the Base Rent applicable immediately preceding the expiration or
termination. Nothing contained herein shall be construed as consent by Lessor to
any holding over by Lessee.

27.  CUMULATIVE REMEDIES. No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies at
law or in equity.

     30.1   SUBORDINATION. This Lease and any Option granted hereby shall be
subject and subordinate to any ground lease, mortgage, deed of trust, or other
hypothecation or security device (collectively, "SECURITY DEVICE"), now or
hereafter placed upon the Premises, to any and all advances made , on the
security thereof, and to all renewals, modifications, and extensions thereof.
Lessee agrees that the holders of any such Security Devices (in this Lease

perform any of the obligations of Lessor under this Lease. Any Lender may elect
to have this Lease and/or any Option granted hereby superior to the lien of its
Security Device by giving written notice thereof to Lessee, whereupon this Lease
and such Options shall be deemed prior to such Security Device, notwithstanding
the relative dates of the documentation or recordation thereof.

     30.2   ATTORNMENT. In the event that lessor transfers title to the
Premises, or the Premises are acquired by another upon the foreclosure or
termination of a Security Device to which this Lease is subordinated (i) Lessee
shall, subject to the non-disturbance provisions of Paragraph 30.3, attorn to
such new owner, and upon request, enter into a new lease, containing ail of the
terms and provisions of this Lease, with such new owner for the remainder of the
term hereof, or, tat the election of such new owner, this Lease shall
automatically become a new Lease between Lessee and such new owner, upon all of
the terms and conditions hereof, for the remainder of the term hereof, and (ii)
Lessor shall thereafter be relieved of any further

                                       35

obligations hereunder and such new owner shall assume ail of Lessor's
obligations hereunder, except that such new owner shall not: (a) be liable for
any act or omission of any prior lessor or with respect to events occurring
prior to acquisition of ownership; (b) be subject to any offsets or defenses
which Lessee might have against any prior lessor, (c) be bound by prepayment of
more than one month's rent, or (d) be liable for the return of any security
deposit paid to any prior lessor.

Lessor after the execution of this Lease, Lessee's subordination of this Lease
shall be subject to receiving a commercially reasonable non-disturbance
agreement (a "NON-DISTURBANCE AGREEMENT") from the Lender which Non-Disturbance
Agreement provides that Lessee's possession of the Premises, and this Lease,
including any options to extend the term hereof, will not be disturbed so long
as Lessee is not in Breach hereof and attorns to the record owner of the
Premises. Further, within 60 days after the execution of this Lease, Lessor
shall use its commercially reasonable efforts to obtain a Non-Disturbance
Agreement from the holder of any pre-existing Security Device which is secured
by the Premises. In the event that Lessor is unable to provide the
Non-Disturbance Agreement within said 60 days, then Lessee may, at Lessee's
;option, directly contact Lender and attempt to negotiate for the execution and
delivery of a Non-Disturbance Agreement.

     30.4   SELF-EXECUTING. The agreements contained in this Paragraph 30 shall

further writings as may be reasonably required to separately document any
subordination, attornment and/or Non-Disturbance Agreement provided for herein.

31.  ATTORNEYS' FEES. If any Party or Broker brings an action or proceeding
involving the Premises whether founded in tort, contract or equity, or to
declare rights hereunder, the Prevailing Party (as hereafter defined) in any
such proceeding, action, or appeal thereon, shall be entitled to reasonable
attorneys' fees. Such fees may be awarded in the same suit or recovered in a
separate suit, whether or not such action or proceeding is pursued to decision
or judgment. The term, "PREVAILING PARTY" shall include, without limitation, a
Party or Broker who substantially obtains or defeats the relief sought, as the
case may be, whether by compromise, settlement, judgment, or the abandonment by
the other Party or Broker of its claim or defense. The attorneys' fees award
shall not be computed in accordance with any court fee schedule, but shall be
such as to fully reimburse ail attorneys' fees reasonably incurred. In addition,
Lessor shall be entitled to attorneys' fees, costs and expenses incurred in the
preparation and service of notices of Default and consultations in connection
therewith, whether or not a legal action is subsequently commenced in connection

Premises; provided, however, that lessor may elect to continue any one or all
existing subtenancies. Lessor's failure within 10 days following any such event

request by Lessee for any Lessor consent, including but not limited to consents
to an assignment, a subletting or the presence or use of a Hazardous Substance,
shall be paid by Lessee upon receipt of an invoice and supporting documentation
therefor. Lessor's consent to any act, assignment or subletting shall not
constitute an acknowledgment that no Default or Breach by Lessee of this Lease
exists, nor shall such consent be deemed a waiver of any then existing Default
or Breach, except as may be otherwise specifically stated in writing by Lessor
at the time of such consent. The failure to specify herein any particular
condition to Lessor's consent shall not preclude the imposition by Lessor at the
time of consent of such further or other conditions as are then reasonable with
reference to the particular matter for which consent is being given. In the
event that either Party disagrees with any determination made by the other
hereunder and reasonably requests the reasons for such determination, the
determining party shall furnish its reasons in writing and in reasonable detail
within 10 business days following such request.

detailed plans and specifications (the "Plans") for the "Tenant Improvements"
(as such term is defined in Paragraph 3.1 below) to be constructed in the
Premises, which shall include a layout and designation of all walls, windows,
offices, rooms, restrooms and other partitioning, and location of computer and
telephone rooms, heavy equipment, plumbing requirements, corridors and any
specific use items required by Lessee, and architectural and engineering
drawings for the Tenant Improvements in a form which is complete to allow a
general. contractor and subcontractors to bid on the job and to obtain all
applicable governmental permits. Lessor shall approve or reasonably disapprove
of Lessee's proposed Space Planner and Mechanical Engineer within three (3)
business days after Lessee's request therefor. The Plans shall include, without
limitation, Lessee's finish schedule for interior decoration of the Premises
including, without limitation, floor coverings or carpets, any special wall
coverings, lighting or other fixtures, painting, finish hardware, detailed
drawings of all shelving and cabinet work, locations of special electrical
outlets, telephones, machinery, electrical equipment and plumbing fixtures. The
architectural, engineering, mechanical and electrical drawings shall be in the
form of final working drawings with details and dimensions for all work to be
performed in the Premises (i.e. electrical, plumbing, HVAC, mechanical and
fire/life-safety systems). Together with the Plans, Lessee shall deliver to
Lessor such additional information regarding the Tenant Improvements as Lessor
may reasonably request. Lessee shall not have the right to add additional usable
square footage to the Premises beyond the existing usable square footage of the
Premises without Lessor's prior written consent, to be given or withheld in
Lessor's sole discretion. Notwithstanding anything to the, contrary contained in
this Exhibit C, Lessee shall provide Lessor with such information as Lessor
shall reasonably require to allow Lessor to proceed to complete Lessor's Shell
and Core Work within the Premises no later than three (3) business days
following Lessor's request from time to time, and Lessee's failure to do so
shall be deemed Tenant Delay.

            1.2. LESSOR APPROVAL OF PLANS. Lessor shall approve or disapprove
the Plans as soon as reasonably possible, but in no event later than five (5)
business days following Lessor's receipt thereof. Lessor's approval of the Plans
shall not be unreasonably withheld, conditioned or delayed. Lessor's disapproval
of the Plans shall be effected by Lessor's delivery to the Space Planner, as
soon as reasonably possible but in no event beyond such five (5) business day
period, of a writing setting forth the reasonable basis for its disapproval.
Within five (5) business days of the delivery by Lessor of its reasonable
objections, the Space Planner shall cause the Plans to be modified and delivered
to Lessor. Lessor shall then approve or disapprove such modified Plans in the
same manner as set forth above as soon as reasonably possible, but in no event
later than five (5) business days from Lessor's receipt thereof. This procedure
shall be followed until

                                       46
<Page>

all reasonable objections of Lessor have been resolved and Lessor has approved
the Plans. Lessee's and Lessor's approval of the Plans shall be evidenced by
their initialing and dating each page thereof. Lessor's review of the Plans as
set forth in this Paragraph 1 shall be for Lessor's sole purpose and shall not
obligate Lessor to review the same for quality, design, fitness for Lessee's
intended use of the Premises, compliance with applicable law or other like
matters. The Plans as approved by Lessor shall be referred to herein as the
"Final Plans." All costs of preparation of and revisions to the Plans and any
Final Plans shall be borne by Lessee, subject to the provisions of Paragraph 3.1
below.

            1.3. PLAN CHECK. Upon Lessor's approval of the Final Plans, the
Space Planner shall submit the Final Plans to the applicable department of
Culver City (the "City") for necessary plan checks and approvals as required by
applicable law. The Space Planner shall provide Lessor with reasonable advance
notice of all its meetings with City personnel, so as to provide Lessor
reasonable opportunity to have a representative accompany the Space Planner to
such meetings, as Lessor may desire, for purposes of allowing Lessor input on
matters affecting the Industrial Center. Any and all plan check corrections
shall be made by the Space Planner, subject to Lessor's approval, within five
(5) business days following receipt of such corrections from the City.

            1.4. TIMELY PERFORMANCE. Lessee shall cause any plans,
specifications, drawings, schedules and documents to be provided by the Space
Planner under this Paragraph 1 to be prepared promptly and delivered to Lessor.
Lessee agrees that all communications with Lessor's architect will be through
Lessor or Lessor's designated representative, so long as any delay in
communications caused by Lessor is not considered a Tenant Delay. Should Lessee
or its employees or agents violate the foregoing prohibition by communicating
directly with Lessor's architect, Lessee shall either pay to Lessor or directly
to Lessor's architect (at Lessor's option) Lessor's architect's charges for its
direct communications with Lessee or Lessee's employees or agents.

            1.5. EXCULPATION. Notwithstanding Lessor's or Lessor's agents
involvement in the preparation of any Plans, and Lessor's approval of the Final
Plans, Lessor shall not have any liability in connection with any errors or
omissions in such Plans, including the Final Plants.

            1.6 CHANGE ORDERS. Notwithstanding anything to the contrary
contained herein, Lessor shall, within five (5) business days after its receipt
from Lessee of a change order to the Final Plans ("Change Order"), either: (i)
approve the Change Order, or (ii) disapprove the Change Order based on the
approval criteria set forth in Paragraph 1.2 above. Lessor's failure to timely
respond to Lessee within such five (5) business day period shall be deemed as
Lessor's approval of the Change Order. Any incremental Tenant Improvement costs
resulting from the Change Order shall be borne by Lessee (subject to
reimbursement out of the T.I. Allowance), and any delay in the Substantial
Completion of Lessor's or Lessee's respective obligations set forth in this
Exhibit resulting from the Change Order shall not serve to delay the date that
the Commencement Date would have otherwise occurred.

     2.     SELECTION OF CONTRACTOR.

            2.1. LESSEE'S SELECTION. Lessee shall have the right to select the
general contractor of its choice to construct Tenant Improvements, so long as
such general contractor is a licensed contractor reasonably acceptable to Lessor
with a minimum of five (5) years experience in tenant improvement construction
in commercial office buildings and in conversions of warehouse space to office
space, and such contractor is familiar with the practices and procedures of
Culver City's Department of Building and Safety. Lessor shall approve or
reasonably disapprove Lessee's choice of contractor within seven (7) business
days after Lessee's request therefor.

            2.2. LESSEE'S CONTRACTOR. The qualified contractor selected by
Lessee ("Lessee's Contractor") shall enter into a written contract with Lessee
for the construction of the Tenant Improvements. Lessor shall have the right to
review and reasonably approve in advance in writing the form and content of such
contract between Lessee and Lessee's Contractor, and specifically the warranty,
indemnity, insurance, pricing and payment provisions of such contract. Lessor
shall approve or reasonably disapprove Lessee's construction contract within
seven (7) business days after Lessee's request therefore.

            2.3. CONSTRUCTION STANDARDS. Lessee's Contractor shall obtain all
necessary permits for and construct the Tenant Improvements in strict accordance
with all applicable codes, ordinances, regulations, laws and the Final Plans.
The Tenant Improvements shall be constructed and completed lien-free and in a
diligent and workmanlike manner. As a condition to Lessee's Contractor's
commencement of work, Lessor shall receive from Lessee's Contractor a
certificate of insurance that names Lessor as an additional insured, from an
insurer meeting the requirements of Paragraph 8 of the Lease, and evidencing
liability, property damage and "course of construction" coverages reasonably
acceptable to Lessor, plus statutorily-required workers compensation insurance
as being in force through the anticipated completion date of the Tenant
Improvements, and providing that Lessor will receive at least thirty (30) days
written notice of any amendments to or cancellation of such coverage. Lessee's
Contractor shall warrant to Lessee and for the benefit of Lessor that the tenant
improvements shall be free from any defects in workmanship and materials for a
period of one (1) year from the date of completion of the Tenant Improvements.
Lessee's Contractor shall coordinate its work with Lessor, and adhere to such
reasonable construction-related rules and procedures as Lessor may now or in the
future reasonably promulgate. Lessee shall permit Lessor or Lessor's
representatives to observe the on-going construction within the Premises to
insure compliance with Lessee's obligations under the Lease and this Exhibit C.
Promptly following the completion of the Tenant Improvements, Lessee shall
obtain from Lessee's Contractor and deliver to Lessor "as-built" or a record set
(containing corrections made at the site) of plans for the Tenant Improvements
in form reasonably acceptable to Lessor.

     3.     TENANT IMPROVEMENT ALLOWANCE.

            3.1. ALLOWANCE AMOUNT. Lessor hereby grants to Lessee a "tenant
improvement allowance" (the "T.I. Allowance") in an amount not to exceed: One
Million Five Hundred Thousand Dollars ($1,500,000.00); The T,.I. Allowance shall
be used by Lessee only for: (i) costs of construction of improvements that are
affixed to the Premises and are included in

                                       48
<Page>

the Final Plans (the "Tenant Improvements"); and (ii), Lessee's out-of-pocket
fees and costs incurred in connection with architectural, engineering and space
planning services pertaining to the Final Plans, and for governmental permits
and telephone/computer/data cabling, provided, however, that not more than Five
Dollars ($5) per square foot of the Premises may be utilized for the costs
described in this clause (ii). Lessee shall not be entitled to receive or apply
any portion of the T.I. Allowance for any other purpose, including without
limitation for the purchase of moveable furniture or equipment, nor for moving
expenses, nor for the payment of rent due under the Lease. The T.I. Allowance
shall be disbursed by Lessor in accordance with Paragraph 3.2 below.

            3.2. PAYMENT. Provided that Lessee is not then in Default or Breach
under the Lease, the T.I. Allowance, or such lesser amount as may be necessary
to reimburse Lessee for its Tenant Improvement costs, shall be paid by Lessor to
Lessee in monthly installments, as follows: Each monthly installment shall be
paid within thirty (30) days following Lessee's delivery to Lessor of: (i) a
written statement from the Space Planner and Lessee of the percentage of
completion (on a line-item basis) of the Tenant Improvements have been installed
at the Premises to Lessee's satisfaction;. (ii) copies of all invoices from
Lessee's Contractor, all subcontractors and all other suppliers of labor and
material to the Tenant Improvements, whether or not being paid for out of the
T.I. Allowance, pertaining to the work . performed to date; (iii) copies of all
applicable governmental permits, approvals and signed-off inspection cards, for
work completed for which payment is being sought; (iv) ink-executed mechanic's
lien releases in compliance with the applicable provisions of California Civil
Code . Section 3262(d) from Lessee's Contractor and all other suppliers of labor
and material to the Tenant Improvements having mechanics lien rights, or other
reasonable documentary evidence satisfactory to Lessor that neither Lessee's
Contractor nor any subcontractor, laborer or materialman has filed or threatened
to file a mechanic's lien against the Premises or Industrial Center, pertaining
to the work performed to date; and (v) such other information and documentation
pertaining to the Tenant Improvements as Lessor or Lessor's lender may
reasonably request. The final installment shall be equal to the balance of the
T.I. Allowance, and shall be paid promptly following Lessee's delivery to Lessor
of: (i) a written statement from the Space Planner and Lessee that all of the
Tenant Improvements have been completed to their respective satisfaction; (ii)
copies of all invoices from Lessee's Contractor, all subcontractors and all
other suppliers of labor and material to the Tenant Improvements, whether or not
being paid for out of the T.I. Allowance; (iii) copies of all applicable
governmental permits, approvals and signed-off inspection cards, including
without limitation a temporary certificate of occupancy for the Premises issued
by the City; (iv) ink-executed mechanic's lien releases in compliance with
CALIFORNIA CIVIL CODE Section 3262(d) (3) or 3262(d) (4) from Lessee's
Contractor and all other suppliers of labor and material to the Tenant
Improvements having mechanics lien rights, or other reasonable documentary
evidence satisfactory to Lessor that neither Lessee's Contractor nor any
subcontractor, laborer or materialman has filed or threatened to file a
mechanic's lien against the Premises or Industrial Center; and (v) such other
information and documentation pertaining to the Tenant Improvements as Lessor or
Lessor's lender may reasonably request. Notwithstanding the foregoing, however,
should the estimated total cost of the Tenant Improvements exceed the. total
T.I. Allowance, Lessee shall make arrangements reasonably satisfactory to Lessor
to assure payment by Lessee to Lessee's Contractor and all other parties engaged
by Lessee of the excess portion, and the amount of each T.I. Allowance
disbursement payment pursuant to this Paragraph 3.2 shall equal the amount
determined for payment per the previous sentences multiplied by a

                                       49
<Page>

fraction, the numerator of which shall be the total T.I. Allowance and the
denominator of which shall be the estimated total cost of the Tenant
Improvements (as such estimated total cost may be modified from time to time by
change, orders). Further notwithstanding the foregoing, should Lessee initially
elect to construct improvements to allow it to take occupancy of less than the
entire Premises, Lessor shall only fund a pro rata share of the T.I. Allowance,
with the balance funded at such time as the balance of the Premises are improved
for Lessee's occupancy. By way of example only, should Lessee initially elect to
improve only 75 % of the Premises for its occupancy, Lessor shall only be
obligated to fund 75 % of the T.I. Allowance (with such 75 % portion being
funded in monthly installments as provided in the first three sentences of this
Paragraph 3.2); at such time as Lessee improves the balance of the Premises for
its occupancy, Lessor shall fund the balance of the T.I. Allowance (in monthly
installments as provided in the first three sentences of this Paragraph 3.2).

            3.3. SHELL AND CORE WORK. Notwithstanding anything to the contrary
contained in this EXHIBIT C, Lessor at Lessor's expense shall use commercially
reasonable best efforts to cause the "Substantial Completion" (as such term is
defined in Paragraph 5.1 below) of the various components of the work ("Shell
and Core Work") set forth in SCHEDULE 3.3 attached hereto and incorporated by
this reference in the Premises by the various dates set forth in SCHEDULE 3.3,
subject to extension due to "Events of Force Majeure" and "Tenant Delay" (as
such terms are defined in Paragraphs 5.2 and 5.3, respectively, below);
provided, however, that Lessor shall have no liability to Lessee, nor shall the
scheduled Commencement Date of November 1, 2000 be postponed or delayed, if
Lessor is unable for any reason to cause the Substantial Completion of any
aspect of the Shell and Core Work by the particular date indicated in SCHEDULE
3.3, so long as there is Substantial Completion of each aspect of the Shell and
Core Work by November 1, 2000. , Should there not be Substantial Completion of
all Shell and Core Work by November 1, 2000 and Lessee has not taken occupancy
of any portion of the Premises for the conduct of its business by then, then the
Commencement Date shall be postponed until such time as there is Substantial
Completion of all the Shell and Core Work (or any earlier date that Lessee has
taken occupancy of any portion of the Premises for the conduct of its business),
unless the reason for the delay is due to Tenant Delay (in which event the-
Commencement Date shall occur on the date that there would have been Substantial
Completion of the Shell and Core Work but for the Tenant Delay):

     4.     CONSTRUCTION BY LESSEE'S CONTRACTOR. Except as otherwise provided in
the Lease or this EXHIBIT C, Lessor shall not have any responsibility or
obligations whatsoever for the design or construction of any of the Tenant
Improvements or for the timeliness in completion of the Tenant Improvements,
including deficiencies in the quality or adequacy of the labor or material
constructed in the Premises. Except as otherwise provided herein, Lessee
understands and acknowledges that the occurrence of the Commencement Date of the
Original Term is not contingent on the completion of the Tenant Improvements by
Lessee's Contractor.

     5.     CERTAIN DEFINITIONS.

            5.1. SUBSTANTIAL COMPLETION. The date of "Substantial Completion" of
the Shell and Core Work shall be the date that Lessor has substantially
completed Lessor's work described in Paragraph 3.3 above, exclusive of any
Tenant Improvements or other work

                                       50
<Page>

performed by or on behalf of Lessee, and minor "punch list" items of work and
adjustment of Shell and Core Work that can be completed in the following thirty
(30) day period without, in Lessor's reasonable judgment, causing substantial
interference with the construction of Lessee's desired Tenant Improvements.

            5.2. EVENTS OF FORCE MAJEURE. "Events of Force Majeure" shall mean
any acts of God, government or other force beyond the reasonable control of the
parties, whether caused by weather, labor disputes (to the extent the labor
dispute results in a "lock out" of the construction site), governmental actions
or inactions (other than in the normal permitting process), civil commotions,
fire, water, earthquake or other casualty or delay of third parties not under
the control of the parties, whereby the effect of such event results in a party
being prevented from substantially performing during such event and any
reasonable period of time following such event where performance continues to be
substantially hindered or impaired by continuing adverse conditions. For
example, a three (3) day rain deluge may, result in several additional days of
delay as Lessor recovers from the effects of the deluge, except that Lessor
shall make commercially reasonable efforts to minimize any additional delays.

            5.3. TENANT DELAY. The term "Tenant Delay" means Lessee's failure to
furnish the information and/or assistance as and when required of Lessee
pursuant to the Lease, this EXHIBIT C, or the Addendum, and including without
limitation Lessee's failure to render Lessee's approval or disapproval, or
Lessee's or Lessee's agents failure to make submissions to Lessor, within the
time limits specified in this EXHIBIT C; or Lessee's changes in Plans and/or
Final Plans following approval by Lessor and Lessee of the foregoing; or
Lessee's interference with the construction process; or delays caused by
Lessee's agents, including without limitation Lessee's contractors and
subcontractors; or delays resulting from building code .requirements due to any
special requirements of Lessee and/or the requirement for material or labor that
is not readily available, if Lessee fails to make alternative arrangements to
comply with such requirements or select other material or labor that is readily
available within three (3) business days following Lessor's notice. Any
incremental costs to Lessor associated with any Tenant Delay will be passed on
to and shall be borne solely by Lessee. Notwithstanding the foregoing, no Tenant
Delay shall be deemed to have occurred unless and until Lessor has provided
written notice to Lessee specifying the action or inaction that Lessor contends
constitutes Tenant Delay. If such action or inaction is not cured within one (1)
business day after receipt of such notice, then a Tenant Delay, as set forth in
such notice, shall be deemed to have occurred commencing as of the date such
notice is received or deemed received and continuing for the number of business
days the completion of Lessor's Shell and Core Work was in fact delayed as a
direct result of such action or inaction.

            5.4. DELAY IN COMMENCEMENT DATE. Notwithstanding anything to the
contrary contained in this Lease, the Commencement Date shall be delayed by one
(1) business day for each business day of delay in the Substantial Completion of
the Tenant Improvements caused by "Landlord Delay" (as such term is defined
below), including without limitation delays in the Substantial Completion of the
Tenant Improvements caused by Lessor's failure to substantially complete its
Shell and Core Work by the deadlines set forth in .Sections 3.3 for reasons
other than Tenant Delay and Events of Force Majeure. No Landlord Delay shall be
deemed to have occurred unless and until Lessee has provided written notice to
Lessor specifying the action or inaction that Lessee contends constitutes
Landlord Delay. If such action or inaction is not cured

                                       51
<Page>

within one (1) business day after receipt of such notice, then a Landlord Delay,
as set forth in the notice, shall be deemed to have occurred commencing as of
the date such notice is received or deemed received by Lessor and continuing for
the number of days the Substantial Completion of the Premises was in fact
delayed as a direct result of such Landlord Delay. The term."Landlord Delay"
shall mean any delay in the completion of the Tenant Improvements which is due
to any wrongful or negligent act or omission of Lessor or Lessor's agents or
contractors (excluding acts or omissions while acting as agent for Lessee). The
term Landlord Delay shall also include, to the extent the completion of the
Tenant Improvements is delayed as a result thereof: (1) Lessor's delay in
responding to Lessee's requests for authorizations or approvals beyond the time
periods required in this Exhibit C; (2) delay attributable to the wrongful or
negligent acts or failures to act of Lessor or Lessor's agents or contractors;
(3) delay attributable to the wrongful or negligent interference of Lessor or
Lessor's agents or contractors with the completion of the Tenant Improvements,
or the wrongful or negligent failure or refusal of Lessor or Lessor's agents or
contractors to permit Lessee or Lessee's agents or contractors access to and use
of 'the Building or any Building facilities or services; (4) delay attributable
to Lessor giving Lessee incorrect or incomplete building requirements or base
building plans, or revisions made to such building requirements or base building
plans subsequent to the delivery of such items to Lessee; and (5) delay
attributable to Lessor's delay, in violation of the terms of this Exhibit _C, in
administering and paying when due the T.I. Allowance.

            5.5. MISCELLANEOUS. During the period of construction of the Tenant
Improvements prior to the Commencement Date, Lessee and Lessee's contractors,
subcontractors and materialmen shall be charged for all electrical and water
charges in connection with the construction of the Tenant Improvements.

            5.6. Presence of Hazardous Materials. In the event that during the
installation of the Tenant Improvements the Premises are determined to contain
Hazardous Materials (including without limitation asbestos) not brought onto the
Premises by Lessee or Lessee's employees, agents or contractors, then Lessor at
Lessor's sole cost and expense shall remove, encapsulate, contain or otherwise
dispose of such Hazardous Materials in accordance with Applicable Requirements.
