LEASE AGREEMENT

THIS LEASE AGREEMENT (the “Lease”) is made this 25th day of Sepember, 2007,
between HF Logistics I, LLC, a Delaware limited liability company (“Landlord”), and the Tenant
named below.

	 	 	 	 	 	 	 	 	 
	Tenant:	 	Skechers USA, Inc., a Delaware corporation
	Tenant’s Representative:
	 	Paul Galliher	 	 	 	 
	Address and Phone:	 	228 Manhattan Beach Blvd.
	 	 	Manhattan Beach, CA 90266
	 
	 	Telephone:(909) 390-1619	 	 	 	 
	Building:	 	That certain Building, containing
	 	 	approximately 1,812,107 rentable square feet,
	 	 	to be constructed by Landlord in accordance
	 
	 	with the	 	 	 	 
	 	 	provisions of this Lease.
	Project:	 	Rancho Belago Corporate Center
	Premises:	 	The Building, together with the parking
	 	 	areas, landscaped areas and other areas
	 	 	consisting of approximately 88.26 acres
	 	 	situated at the NWC of Theodore Avenue and
	 	 	Eucalyptus Avenue, as shown on the Site Plan
	 	 	attached hereto as Exhibit “A”.
	Delay in Possession:	 	If for any reason (other than a Tenant-Caused
	 	 	Delay, as described in Addendum 2, Section
	 	 	5(d)) Landlord has not achieved Substantial
	 	 	Completion (as defined in Addendum 2, Section
	 	 	5(a)) of the Landlord Improvements (as
	 	 	defined in Addendum 2, Section 1(a)) by
	 	 	January 1, 2009, Tenant shall have no right
	 	 	to terminate this Lease or to pursue any
	 	 	other rights or remedies against Landlord,
	 	 	but in such event Tenant shall have the
	 	 	following rights: Tenant may lease other
	 	 	premises (the “Other Premises”) which Tenant
	 	 	determines, in good faith, are necessary to
	 	 	meet the demands of Tenant’s business
	 	 	operations. The selection of the Other
	 	 	Premises shall be made solely by Tenant, but
	 	 	in negotiating a lease for the Other
	 	 	Premises, Tenant shall take into
	 	 	consideration the amount of time which is
	 	 	then estimated by Landlord to achieve
	 	 	Substantial Completion of the Landlord
	 	 	Improvements. Tenant will provide Landlord
	 	 	with a copy of the proposed lease for the
	 	 	Other Premises before Tenant executes same,
	 	 	and will give due consideration to any
	 	 	comments which Landlord may provide as long
	 	 	as such comments are provided to Tenant
	 	 	within three (3) business days after the copy
	 	 	of the proposed lease (or any revised drafts
	 	 	thereof) are delivered to Landlord. Tenant
	 	 	will act reasonably in attempting to lease
	 	 	the Other Premises at the lowest cost
	 	 	available (which not only refers to amount of
	 	 	rent and pass-through expenses, but also to
	 	 	the term of the lease) while still meeting
	 	 	Tenant’s anticipated business requirements.
	 	 	Notwithstanding the foregoing, Landlord
	 	 	acknowledges that Tenant will have limited
	 	 	alternatives for Other Premises and that
	 	 	Tenant shall have sole discretion in entering
	 	 	into a lease for the Other Premises.
	 	 	Landlord agrees to reimburse Tenant for the
	 	 	actual costs incurred by Tenant for the Other
	 	 	Lease, not to exceed $2,200,000 in total.
	 	 	Such reimbursement will be limited to base
	 	 	rent and pass-throughs (of taxes, insurance
	 	 	and operating or common area expenses), and
	 	 	shall not include any legal or other
	 	 	professional fees for negotiating such lease,
	 	 	moving expenses, fixturizing expenses or any
	 	 	expenses which relate to Tenant’s business
	 	 	operations (e.g. utilities and services).
	 	 	Landlord will, at Landlord’s option, either
	 	 	pay such costs directly to the landlord of
	 	 	the Other Premises when due, or will
	 	 	reimburse Tenant for such costs within five
	 	 	(5) days after receipt of demand from Tenant
	 	 	(and documentation evidencing the expenditure
	 	 	by Tenant of such costs).
	 	 	If Tenant enters into a lease of the Other
	 	 	Premises, it will use best efforts to secure
	 	 	the prior approval of the landlord thereunder
	 	 	to allow the assignment of the lease or a
	 	 	sublease of the Other Premises after Tenant
	 	 	vacates the Other Premises, either without
	 	 	such landlord’s consent, or subject to as
	 	 	minimal approval rights as possible.
	 	 	Further, the provisions of Addendum 4,
	 	 	Section 7 shall apply to the Other Lease to
	 	 	the same extent as they apply to the Prior
	 	 	Lease (except for those which by their nature
	 	 	only apply to the Prior Lease).
	 	 	Landlord acknowledges that Tenant will be
	 	 	required to order certain equipment (the
	 	 	“Pre-Ordered Equipment”) in advance of the
	 	 	date of Substantial Completion of the
	 	 	Landlord Improvements. After ordering the
	 	 	Pre-Ordered Equipment, Tenant will advise
	 	 	Landlord of the nature of the Pre-Ordered
	 	 	Equipment and its anticipated delivery date,
	 	 	and will provide Landlord with periodic
	 	 	status reports. Tenant will use reasonable
	 	 	commercial efforts to delay the delivery of
	 	 	the Pre-Ordered Equipment if the date of
	 	 	Substantial Completion of the Landlord
	 	 	Improvements is delayed, provided that any
	 	 	out-of-pocket cost of such delay in delivery
	 	 	shall be paid or reimbursed to Tenant by
	 	 	Landlord. If Landlord has not achieved
	 	 	Substantial Completion of the Landlord
	 	 	Improvements (other than because of a
	 	 	Tenant-Caused Delay) by January 1, 2009,
	 	 	Landlord shall be responsible to pay or
	 	 	reimburse Tenant for the storage of the
	 	 	Pre-Ordered Equipment until such time as it
	 	 	can be properly installed at the Premises.
	 	 	In this regard, Landlord may elect to have
	 	 	the Pre-Ordered Equipment stored within the
	 	 	Premises (if lawfully permitted to do so and
	 	 	if the storage area can be reasonably
	 	 	secured) or Landlord may direct that it be
	 	 	stored at another location reasonably
	 	 	selected by Tenant but in Tenant’s sole
	 	 	discretion. Landlord will pay the costs of
	 	 	storage (if not on the Premises), the costs
	 	 	of delivery of the Pre-Ordered Equipment to
	 	 	the Premises (if stored offsite), but not the
	 	 	cost of installation or the cost of delivery
	 	 	to the Premises if storage is on-site), and
	 	 	Tenant’s cost of insuring same. Landlord
	 	 	shall have no liability to Tenant for any
	 	 	loss or any damage to the Pre-Ordered
	 	 	Property (including but not limited to any
	 	 	claims for lost profits or other
	 	 	consequential damages) during the period of
	 	 	storage or during transit from any on-site
	 	 	storage location to the Premises, from any
	 	 	cause whatsoever (any potential claims of
	 	 	Tenant in that regard being expressly waived
	 	 	by Tenant), whether stored on the Premises or
	 	 	elsewhere, it being understood that Tenant
	 	 	will look solely to its insurance carrier in
	 	 	the event of any such loss. Landlord’s
	 	 	obligation to pay or reimburse Tenant for the
	 	 	cost of storage of the Pre-Ordered Equipment
	 	 	shall end when Landlord has achieved
	 	 	Substantial Completion of the Landlord
	 	 	Improvements and, if stored offsite, the
	 	 	Pre-Ordered Equipment has been delivered to
	 	 	the Premises (which shall be done promptly by
	 	 	Tenant upon receipt of notice from Landlord
	 	 	of the date of Substantial Completion).
	Lease Term:	 	Beginning on the Commencement Date and ending
	 	 	on the last day of the 132nd full calendar
	 	 	month thereafter (the “Termination Date”).
	Commencement Date:	 	The earlier of (a) 30 days after the date
	 	 	that the Premises has been Substantially
	 	 	Completed (as defined in Addendum 2) or (b)
	 	 	the date Tenant shall commence its business
	 	 	operations in the Premises. The parties
	 	 	agree to execute a written instrument which
	 	 	confirms the Commencement Date and the
	 	 	Termination Date promptly after such dates
	 
	 	have been determined.

1. Granting Clause. In consideration of the obligation of Tenant to pay rent as herein
provided and in consideration of the other terms, covenants, and conditions hereof, Landlord leases
to Tenant, and Tenant takes from Landlord, the Premises, to have and to hold for the Lease Term,
subject to the terms, covenants and conditions of this Lease.

2. Acceptance of Premises. Except as otherwise set forth in the Lease, Tenant shall accept
the Premises in its condition as of the Commencement Date, subject to all applicable laws,
ordinances, regulations, covenants and restrictions. Landlord has made no representation or
warranty as to the suitability of the Premises for the conduct of Tenant’s business, and Tenant
waives any implied warranty that the Premises are suitable for Tenant’s intended purposes. Except
as otherwise set forth in the Lease, in no event shall Landlord have any obligation for any defects
in the Premises or any limitation on its use. The taking of possession of the Premises shall be
conclusive evidence that Tenant accepts the Premises and that the Premises were in good condition
at the time possession was taken except for items that are Landlord’s responsibility under the
Lease and any punchlist items agreed to in writing by Landlord and Tenant. Notwithstanding
anything to the contrary set forth herein, Landlord represents and warrants that as of the
Commencement Date (i) the structural integrity of the Premises, including without limitation, the
foundation, roof, and any load bearing or retaining walls, is free from any material latent or
patent defects, (ii) Landlord is currently not the subject of any bankruptcy or insolvency
proceeding, (iii) the Premises shall be in compliance with all Legal Requirements (hereinafter
defined) in effect as of the Commencement Date of this Lease, (iv) Landlord has full power, right
and authority to execute and perform this Lease and all limited liability company action necessary
to do so has been duly taken, and (v) there are no covenants, conditions, restrictions or
agreements in existence which are not part of the public records which will adversely affect the
permitted use of the Premises. If any of the foregoing representations or warranties are
inaccurate, Landlord shall, promptly after receipt of written notice from Tenant setting forth with
specificity the nature and extent of such inaccuracy, rectify the same at Landlord’s expense.

3. Use. The Premises shall be used only for the purpose of receiving, storing, packaging,
shipping and selling (but limited to wholesale sales) products, materials and merchandise made
and/or distributed by Tenant and for such other lawful purposes as may be incidental thereto;
provided, however, with Landlord’s prior written consent, and provided that such use is permissible
under applicable zoning and other Legal Requirements. Tenant may also use the Premises for light
manufacturing. Tenant shall not conduct or give notice of any auction, liquidation, or going out
of business sale on the Premises, without Landlord’s prior written consent which shall not be
unreasonably withheld, conditioned or delayed. Tenant will use the Premises in a careful, safe and
proper manner and will not commit waste, overload the floor or structure of the Premises or subject
the Premises to use that would damage the Premises. Tenant shall not permit any objectionable or
unpleasant odors, smoke, dust, gas, noise, or vibrations to emanate from the Premises, or take any
other action that would constitute a nuisance or would disturb, unreasonably interfere with, or
endanger Landlord or any tenants of the Project. For purposes of the preceding sentence, noise or
vibrations from Tenant’s material handling system shall not be considered “objectionable” by
Landlord. Outside storage, including without limitation, storage of non-operable trucks and other
non-operable vehicles, is prohibited without Landlord’s prior written consent; provided, however,
that subject to applicable Legal Requirements, Tenant shall be permitted to park trucks and
trailers used in Tenant’s business operations on and from the Premises overnight at the truck docks
of the Premises and Tenant’s customers shall be permitted to park their vehicles overnight from
time to time in the parking areas of the Premises, provided such customer’s vehicles and such
trucks and trailers are at all times in operable condition and there is no interference with the
ingress and egress of the Project. Except as otherwise set forth in the Lease, Tenant, at its sole
expense, shall use and occupy the Premises in compliance with all laws, including, without
limitation, the Americans With Disabilities Act, orders, judgments, ordinances, regulations, codes,
directives, permits, licenses, covenants and restrictions now or hereafter applicable to the
Premises (collectively, “Legal Requirements”). Tenant shall, at its expense, make any alterations
or modifications, within or without the Premises, that are required by Legal Requirements related
to Tenant’s specific use or occupation of the Premises. Tenant will not use or permit the Premises
to be used for any purpose or in any manner that would void Tenant’s or Landlord’s insurance,
increase the insurance risk, or cause the disallowance of any sprinkler credits. If any increase
in the cost of any insurance on the Premises or the Project is caused by Tenant’s use or occupation
of the Premises, or because Tenant vacates the Premises, then Tenant shall pay the amount of such
increase to Landlord. Any occupation of the Premises by Tenant prior to the Commencement Date
shall be subject to all obligations of Tenant under this Lease.

Notwithstanding anything contained herein to the contrary, Tenant’s obligations hereunder
shall relate only to the interior of the Premises and any changes to the Premises or the Building
that relate solely to the specific manner of use of the Premises by Tenant, and Landlord shall make
all other additions to or modifications of the Premises required from time to time by Legal
Requirements. The cost of such additions or modifications made by Landlord shall be included in
Operating Expenses pursuant to Paragraph 6 of this Lease, except for those additions or
modifications which are Landlord’s sole responsibility pursuant to the provisions of this Lease.

Landlord represents that the improvements constructed or installed by Landlord pursuant to the
Construction Addendum attached to this Lease shall comply in all material respects with all
applicable covenants or restrictions of record and all applicable laws, building codes, regulations
and ordinances in effect on the Commencement Date of this Lease.

4. Base Rent. Tenant shall pay Base Rent in the amount set forth above. The first month’s
Base Rent and the first monthly installment of estimated Operating Expenses (as hereafter defined)
shall be due and payable on the date hereof, and Tenant promises to pay to Landlord in advance,
without demand, deduction or set-off, monthly installments of Base Rent on or before the first day
of each calendar month succeeding the Commencement Date. Payments of Base Rent for any fractional
calendar month shall be prorated. All payments required to be made by Tenant to Landlord hereunder
shall be payable at such address as Landlord may specify from time to time by written notice
delivered in accordance herewith. The obligation of Tenant to pay Base Rent and other sums to
Landlord and the obligations of Landlord under this Lease are independent obligations. Tenant
shall have no right at any time to abate, reduce, or set-off any rent due hereunder except as may
be expressly provided in this Lease. If Tenant is delinquent in any monthly installment of Base
Rent or estimated Operating Expenses for more than 10 days, Tenant shall pay to Landlord on demand
a late charge equal to 5 percent of such delinquent sum. The provision for such late charge shall
be in addition to all of Landlord’s other rights and remedies hereunder or at law and shall not be
construed as a penalty.

5. Security Deposit. Intentionally Omitted.

6. Operating Expense Payments. During each month of the Lease Term, on the same date that
Base Rent is due, Tenant shall pay Landlord an amount equal to 1/12 of the annual cost, as
estimated by Landlord from time to time, of the Operating Expenses for the Premises. Payments
thereof for any fractional calendar month shall be prorated. The term “Operating Expenses” means
all costs and expenses incurred by Landlord with respect to the ownership, maintenance, and
operation of the Premises including, but not limited to costs of: Taxes (hereinafter defined) and
fees payable to tax consultants and attorneys for consultation and contesting taxes; insurance;
maintenance, repair and replacement of the Premises, including without limitation, paving and
parking areas, non-structural areas of the roof (including the roof membrane), alleys, and
driveways, mowing, landscaping, exterior painting, amounts paid to contractors and subcontractors
for work or services performed in connection with any of the foregoing; charges or assessments of
any association to which the Premises is subject (although it is understood that no such
association exists as of the date of execution of this Lease); property management fees payable to
a property manager, including any affiliate of Landlord; security services, if any; trash
collection, sweeping and removal; and additions or alterations made by Landlord to the Premises in
order to comply with Legal Requirements enacted after the Commencement Date (other than those
expressly required herein to be made by and paid for exclusively by Tenant or Landlord) or that are
appropriate to the continued operation of the Premises as a warehouse and distribution facility in
the market area. The cost of additions or alterations or repairs that are required to be
capitalized for federal income tax purposes shall be amortized on a straight line basis over a
period equal to the useful life thereof for federal income tax purposes. Operating Expenses do not
include amortization for capital repairs and capital replacements required to be made by Landlord
under Paragraph 10 of this Lease, costs of Restoration to the extent of Net Proceeds received by
Landlord with respect thereto, or leasing commissions. Further, Operating Expenses shall not mean
or include: (i) costs incurred in connection with the initial construction of the Premises, or
correction of defects in design or construction; (ii) interest, principal, or other payments on
account of any indebtedness that is secured by any encumbrance on any part of the Premises, or
rental or other payments under any ground lease, or any payments in the nature of returns on or of
equity of any kind; (iii) costs of selling, syndicating, financing, mortgaging or hypothecating
any part of or interest in the Premises; (iv) taxes on the income of Landlord or Landlord’s
franchise taxes (unless any of said taxes are hereafter instituted by applicable taxing authorities
in substitution for ad valorem real property taxes); (v) depreciation; (vi) Landlord’s overhead
costs, including equipment, supplies, accounting and legal fees, rent and other occupancy costs or
any other costs associated with the operation or internal organization and function of Landlord as
a business entity (but this provision does not prevent the payment of a management fee to Landlord
as provided in this Paragraph 6); (vii) fees or other costs for professional services provided by
space planners, architects, engineers, and other similar professional consultants, real estate
commissions, and marketing and advertising expenses; (viii) costs of defending or prosecuting
litigation with any party, unless a favorable judgment would reduce or avoid an increase in
Operating Expenses, or unless the litigation is to enforce compliance with Rules and Regulations of
the Project, or other standards or requirements for the general benefit of the tenants in the
Project; (ix) costs incurred as a result of Landlord’s violation or breach of this Lease or of any
other lease, contract, law or ordinance, including fines and penalties; (x) late charges, interest
or penalties of any kind for late or other improper payment of any public or private obligation,
including ad valorem taxes; (xi) costs of removing Hazardous Materials or of correcting any other
conditions in order to comply with any environmental law or ordinance (but this exclusion shall not
constitute a release by Landlord of Tenant for any such costs for which Tenant is liable pursuant
to Paragraph 30 of this Lease); (xii) costs for which Landlord is reimbursed from any other
source; (xiii) costs related to any building or land not included in the Premises; (xiv) the part
of any costs or other sum paid to any affiliate of Landlord that may exceed the fair market price
or cost generally payable for substantially similar goods or services in the area of the Premises;
(xv) bad debt expenses; (xvi) costs arising from Landlord’s charitable or political contributions,
if any; and (xvii) the cost of Landlord’s compliance with the provisions of Paragraphs 2, 3 or
Addendum 4 hereof, or any other costs which are charged to Landlord and not to be borne by Tenant
under the terms of the Lease.

Notwithstanding anything contained herein to the contrary, the property management fees
payable to a property manager, including any affiliate of Landlord as set forth in this Paragraph 6
shall not exceed 2% of the gross monthly revenues collected from Tenant.

Landlord shall provide Tenant within 90 days following the final day of the calendar year
Landlord’s itemized year-end operating expense reconciliation reports which reference and include
all applicable Operating Expenses for such year. Upon Tenant’s written request (which request
shall be limited to once in a calendar year), Landlord shall provide photocopies of invoices, bills
and other verification to substantiate Operating Expenses. If Tenant’s total payments of estimated
Operating Expenses for any year are less than the actual Operating Expenses for such year, then
Tenant shall pay the difference to Landlord within 30 days after demand, and if more, then Landlord
shall retain such excess and credit it against Tenant’s next payment of Operating Expenses. For
purposes of calculating Operating Expenses, a year shall mean a calendar year except the first
year, which shall begin on the Commencement Date, and the last year, which shall end on the
expiration of this Lease.

7. Utilities. Tenant shall pay for all water, gas, electricity, heat, light, power,
telephone, sewer, sprinkler services, refuse and trash collection, and other utilities and services
used on the Premises, all maintenance charges for utilities, and any storm sewer charges or other
similar charges for utilities imposed by any governmental entity or utility provider, together with
any taxes, penalties, surcharges or the like pertaining to Tenant’s use of the Premises. All
utilities shall be separately metered or charged directly to Tenant by the provider. No
interruption or failure of utilities shall result in the termination of this Lease or the abatement
of rent.

Landlord may, at its sole expense, install solar panels on the roof of the Premises which will
generate electricity which will be supplied to the Premises (which may flow directly into the power
grid established by the electrical utility provider selected by Tenant). Tenant agrees to
cooperate with Landlord (at no expense to Tenant) in connection with such installation, including
any metering system which Landlord may elect to install, and Tenant agrees to utilize the
electrical power generated by such solar panel system when it is available. To the extent that
Tenant’s electrical bill is reduced (either directly or indirectly, which may be effectuated by
means of credits and/or vouchers provided to Tenant by Landlord or by the electrical service
provider) by virtue of Tenant’s use of the electrical power generated by such solar panel system,
Tenant will pay a like amount (including any applicable sales tax) to Landlord as payment for the
cost of providing such electrical power; provided, however, that under no circumstances will the
total amount paid to Landlord and the electrical utility provider exceed the amount which Tenant
would otherwise have paid to the electrical utility provider had the solar panel system not been
utilized. Payments to Landlord shall be made monthly along with the payments of Base Rent, for the
cost of electrical power for the previous month. Landlord shall not be responsible to Tenant for
any disruption or any other problem involving the electrical service supplied by such solar panels.
Tenant acknowledges that electricity may only be provided from such solar panels during daylight
and that accordingly, Tenant will still need to obtain and maintain its own electrical service
(24/7) from an electrical utility provider.

8. Taxes. Landlord shall pay all taxes, assessments and governmental charges (collectively
referred to as “Taxes”) that accrue against the Premises during the Lease Term, including any
increased Taxes resulting from the sale or other disposition of the Premises by Landlord, or any
other change of ownership which results in the reassessment of Taxes. Taxes shall be included in
the computation of Operating Expenses charged to Tenant. Landlord may contest by appropriate legal
proceedings the amount, validity, or application of any Taxes or liens thereof. If Landlord fails
to contest the real estate taxes, Tenant shall have the right to request Landlord to contest such
taxes, and Landlord shall so contest, at Tenant’s sole cost and expense (including, without
limitation, Landlord’s reasonable attorneys’ fees and reasonable fees payable to tax consultants
and attorneys for consultation and contesting taxes) , if, in Landlord’s reasonable judgment, such
contest is warranted; provided, however, Tenant’s request of such contesting of Taxes shall be
limited to one request in a calendar year. Landlord shall cooperate in the institution and
prosecution of any such proceedings of contesting taxes and will execute any documents reasonably
required therefor. All reductions, refunds, or rebates of Taxes paid or payable by Tenant shall
belong to Tenant whether as a consequence of a Tenant proceeding or otherwise. All capital levies
or other taxes assessed or imposed on Landlord upon the rents payable to Landlord under this Lease
and any franchise tax, any excise, transaction, sales or privilege tax, assessment, levy or charge
measured by or based, in whole or in part, upon such rents from the Premises and/or the Project or
any portion thereof shall be paid by Tenant to Landlord monthly in estimated installments or upon
demand, at the option of Landlord, as additional rent; provided, however, in no event shall Tenant
be liable for any net income taxes imposed on Landlord unless such net income taxes are in
substitution for any Taxes payable hereunder. If any such tax or excise is levied or assessed
directly against Tenant, then Tenant shall be responsible for and shall pay the same at such times
and in such manner as the taxing authority shall require. Tenant shall be liable for all taxes
levied or assessed against any personal property or fixtures placed in the Premises, whether levied
or assessed against Landlord or Tenant.

9. Insurance. Landlord shall maintain special form (including theft) property insurance
covering the full replacement cost of the Building and other improvements on the Premises.
Landlord may, but is not obligated to, maintain such other insurance and additional coverages as it
may deem necessary, including, but not limited to, commercial liability insurance or rent loss
insurance and earthquake insurance and terrorism insurance, if such insurance is customarily
required by lenders with respect to comparable buildings in the market area of the Premises, and if
the cost thereof is commercially reasonable. All such insurance shall be included as part of the
Operating Expenses charged to Tenant. The Building (and such other improvements) may be included
in a blanket policy (in which case the cost of such insurance allocable to the Building and such
other improvements will be determined by Landlord based upon the insurer’s cost calculations).
Tenant shall also reimburse Landlord for any increased premiums or additional insurance which
Landlord reasonably deems necessary as a result of Tenant’s use of the Premises.

Tenant, at its expense, shall maintain during the Lease Term: all risk property insurance
covering the full replacement cost of all property and improvements installed or placed in the
Premises by Tenant at Tenant’s expense; worker’s compensation insurance with no less than the
minimum limits required by law; employer’s liability insurance with such limits as required by law;
and commercial liability insurance, with a minimum limit of $1,000,000 per occurrence and a minimum
umbrella limit of $1,000,000, for a total minimum combined general liability and umbrella limit of
$2,000,000 (together with such additional umbrella coverage as Landlord may reasonably require) for
property damage, personal injuries, or deaths of persons occurring in or about the Premises.
Landlord may from time to time require reasonable increases in any such limits. The commercial
liability policies shall name Landlord and any Lender as an additional insured, insure on an
occurrence and not a claims-made basis, be issued by insurance companies which are reasonably
acceptable to Landlord, not be cancelable unless 30 days’ prior written notice shall have been
given to Landlord, contain a hostile fire endorsement and a contractual liability endorsement and
provide primary coverage to Landlord (any policy issued to Landlord providing duplicate or similar
coverage shall be deemed excess over Tenant’s policies). Such policies or certificates thereof
shall be delivered to Landlord by Tenant upon commencement of the Lease Term and upon each renewal
of said insurance.

Without affecting any other rights or remedies, Tenant and Landlord 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 Landlord or Tenant, as the case may be, so long as the insurance is not invalidated
thereby.

Except in the case of negligence or breach of this Lease by Landlord or its agents, neither
Landlord nor its agents shall be liable under any circumstances for: (i) injury or damage to the
person or goods, wares, merchandise or other property of Tenant, Tenant’s employees, contractors,
invitees, customers, or any other person in or about the Premises, whether such damage or injury is
caused by or results from fire, steam, electricity, gas, water or rain, indoor air quality, the
presence of mold or from the breakage, leakage, obstruction or other defects of pipes, fire
sprinklers, wires, appliances, plumbing, HVAC or lighting fixtures, or from any other cause,
whether the said injury or damage results from conditions arising upon the Premises or upon other
portions of the Project or from other sources or places, (ii) injury to Tenant’s business or for
any loss of income or profit therefrom.

10. Landlord’s Repairs. Landlord shall maintain, at its expense (and not as part of Operating
Expenses), the structural components of the roof, foundation, and exterior walls of the Building in
good repair, reasonable wear and tear and uninsured losses and damages caused by Tenant, its agents
and contractors excluded. The term “walls” as used in this Paragraph 10 shall not include windows,
glass or plate glass, doors or overhead doors, special store fronts, dock bumpers, dock plates or
levelers, or office entries. Tenant shall promptly give Landlord written notice of any repair
required by Landlord pursuant to this Paragraph 10, after which Landlord shall have a reasonable
opportunity to repair.

Landlord shall also be responsible for the repair, maintenance and upkeep of the
non-structural portions of the roof, foundation and exterior walls (including exterior wall
painting), parking areas, driveway, alleys and all landscaped areas and grounds, and the fire
sprinklers and fire protection systems. Landlord shall also be responsible for the upkeep and
maintenance (in accordance with applicable Legal Requirements) of the areas of the Premises which
are subject to the Water Quality Management Plan. The costs and expenses of the foregoing shall be
included in the computation of Operating Expenses charged to Tenant.

In the event of an emergency, Tenant shall have the right to make such temporary, emergency
repairs (and only such temporary, emergency repairs) to the roof, foundation or exterior walls of
the Project as may be reasonably necessary to prevent material damage to Tenant’s property at the
Premises and/or personal injury to Tenant’s employees at the Premises (provided Tenant first
attempts to notify Landlord telephonically of such emergency and notifies Landlord of such
circumstances in writing as soon as practicable thereafter). In such event, Landlord shall
reimburse Tenant for the reasonable, out-of-pocket costs actually incurred by Tenant in making such
repairs. If Landlord fails to reimburse Tenant for the reasonable, out-of-pocket costs incurred by
Tenant in making such repairs, up to but not to exceed $25,000.00 with respect to such emergency,
within 30 days after demand therefor, accompanied by supporting evidence of the costs incurred by
Tenant, then Tenant may bring an action for damages against Landlord to recover such costs,
together with interest thereof at the rate provided for in Paragraph 37(j) of the Lease, and
reasonable attorney’s fees incurred by Tenant in bringing such action for damages. In no event,
however, shall Tenant have a right to terminate the Lease.

11. Tenant’s Repairs. Subject to Landlord’s obligations as set forth in Paragraph 10 of this
Lease, and subject to the provisions of Paragraphs 15 and 16, and subject to the right of Landlord
set forth below in this Paragraph 11, Tenant, at its expense, shall repair, replace and maintain in
good condition, reasonable wear and tear, and losses and damages caused by Landlord, its agents and
contractors excepted, all portions of the Premises including, without limitation, dock and loading
areas, truck doors, plumbing, water and sewer lines up to points of common connection, entries,
doors, ceilings, windows, interior walls, interior side of demising walls, heating, ventilation and
air conditioning systems. Such repair and replacements include capital expenditures and repairs
whose benefit may extend beyond the Lease Term. Heating, ventilation and air conditioning systems
shall be maintained at Tenant’s expense pursuant to maintenance service contracts entered into by
Tenant. The scope of services and contractors under such maintenance contracts shall be reasonably
approved by Landlord. If Tenant fails to perform any repair or replacement for which it is
responsible, Landlord may perform such work and be reimbursed by Tenant within 10 days after demand
therefor. Subject to Paragraphs 15 and 16, Tenant shall bear the full cost of any repair or
replacement to any part of the Building or other improvements to the Premises or the Project that
results from damage caused by Tenant, its agents, contractors, or invitees and any repair that
benefits only the Premises.

12. Tenant-Made Alterations and Trade Fixtures. Any alterations, additions, or improvements
made by or on behalf of Tenant to the Premises (“Tenant-Made Alterations”) in excess of $50,000
shall be subject to Landlord’s prior written consent, which shall not be unreasonably withheld,
conditioned or delayed, provided that such alteration does not materially affect the structure or
the roof of the Building, or modify the utility systems of the Project. Tenant shall cause, at its
expense, all Tenant-Made Alterations to comply with insurance requirements and with Legal
Requirements and shall construct at its expense any alteration or modification required by Legal
Requirements as a result of any Tenant-Made Alterations. All Tenant-Made Alterations shall be
constructed in a good and workmanlike manner by contractors reasonably acceptable to Landlord and
only good grades of materials shall be used. All plans and specifications for any Tenant-Made
Alterations shall be submitted to Landlord for its approval. Landlord may monitor construction of
the Tenant-Made Alterations. Tenant shall reimburse Landlord for its reasonable costs in reviewing
plans and specifications and in monitoring construction. Landlord’s right to review plans and
specifications and to monitor construction shall be solely for its own benefit, and Landlord shall
have no duty to see that such plans and specifications or construction comply with applicable laws,
codes, rules and regulations. Tenant shall provide Landlord with the identities and mailing
addresses of all persons performing work or supplying materials, prior to beginning such
construction, and Landlord may post on and about the Premises notices of non-responsibility
pursuant to applicable law. Tenant shall furnish security or make other arrangements reasonably
satisfactory to Landlord to assure payment for the completion of all work free and clear of liens
and shall provide certificates of insurance for worker’s compensation and other coverage in amounts
and from an insurance company satisfactory to Landlord protecting Landlord against liability for
personal injury or property damage during construction. Upon completion of any Tenant-Made
Alterations, Tenant shall deliver to Landlord sworn statements setting forth the names of all
contractors and subcontractors who did work on the Tenant-Made Alterations and final lien waivers
from all such contractors and subcontractors. Upon surrender of the Premises, all Tenant-Made
Alterations and any leasehold improvements constructed by Landlord or Tenant shall remain on the
Premises as Landlord’s property, except to the extent Landlord requires removal at Tenant’s expense
of any such items or Landlord and Tenant have otherwise agreed in writing in connection with
Landlord’s consent to any Tenant-Made Alterations. Upon Tenant’s written request, Landlord shall
provide Tenant, at the time of Tenant’s request for approval of Tenant-Made Alterations, a list of
which Tenant-Made Alterations Landlord will require Tenant to remove upon surrender of the
Premises. Tenant shall repair any damage caused by such removal.

Tenant, at its own cost and expense and without Landlord’s prior approval, may erect such
shelves, bins, machinery and trade fixtures (collectively “Trade Fixtures”) in the ordinary course
of its business provided that such items do not alter the basic character of the Premises, do not
overload or damage the Premises, and may be removed without injury to the Premises, and the
construction, erection, and installation thereof complies with all Legal Requirements and with
Landlord’s requirements set forth above. Upon surrender or vacating of the Premises, Tenant shall
remove its Trade Fixtures and shall repair any damage caused by such removal.

13. Signs and Roof. Tenant shall not make any changes to the exterior of the Premises,
install any exterior lights, decorations, balloons, flags, pennants, banners, or painting, or erect
or install any signs, windows or door lettering, placards, decorations, or advertising media of any
type which can be viewed from the exterior of the Premises, without Landlord’s prior written
consent, which consent shall not be unreasonably withheld or delayed. Without limiting the
generality of the foregoing, Tenant may not paint its name on the roof of the Building. Upon
surrender or vacation of the Premises, Tenant shall have removed all signs and repair, paint,
and/or replace the building facia surface to which its signs are attached. Tenant shall obtain all
applicable governmental permits and approvals for sign and exterior treatments. All signs,
decorations, advertising media, blinds, draperies and other window treatment or bars or other
security installations visible from outside the Premises shall be subject to Landlord’s approval
and conform in all respects to Landlord’s requirements. The use of the roof shall be reserved
exclusively to Landlord for any use which does not interfere with Tenant’s business operations
including, but not limited to the installation of solar panels (as described in Section 7) or
leasing space to cellular telephone service providers for cell tower placement.

14. Parking. Tenant shall be entitled to parking only within the boundaries of the Premises
which are designated as parking areas on the Site Plan.

15. Damage and Destruction. If at any time during the Lease Term the Premises are damaged by
a fire or other casualty, Landlord shall notify Tenant within 30 days after such damage as to the
amount of time Landlord reasonably estimates it will take to restore the Premises.

(a) If the Premises are damaged by fire or other casualty covered by insurance which Landlord
is required to carry hereunder (and for which there are sufficient insurance proceeds available,
excluding any deductible, to repair the damage), then Landlord shall, subject to Force Majeure
events and delays arising from the collection of insurance proceeds, repair such damage (excluding
the improvements installed by Tenant or by Landlord and paid by Tenant) within 9 months and this
Lease shall continue in full force and effect. Tenant at Tenant’s expense shall promptly perform,
subject to delays arising from the collection of insurance proceeds, or from Force Majeure events,
all repairs or restoration not required to be done by Landlord. If the Premises are damaged by
fire or other casualty and there is no insurance or insufficient insurance proceeds (excluding any
deductible) to repair the Premises, then Landlord may, at its option, either terminate this Lease,
by giving notice to Tenant within 30 days of the date of damage, or repair such damage in the same
manner as if there had been sufficient insurance proceeds available, at Landlord’s expense, and if
Landlord so elects to repair, then the Lease shall continue in full force and effect. Landlord’s
failure to deliver a termination notice to Tenant as aforesaid, shall be deemed Landlord’s election
to repair the Premises.

(b) If the if the Premises are damaged during the last 18 months of the Lease Term, and Tenant
has not exercised its option to renew, as applicable (as hereinafter described in Addendum 3), and
if the restoration time is estimated to exceed 6 months and such damage materially interferes with
Tenant’s use of the Premises, Tenant may elect to terminate this Lease upon notice to Landlord
given no later than 30 days after Tenant’s receipt of Landlord’s written notice of its estimate of
the amount of time it will take to repair the Premises. If Tenant elects not to terminate this
Lease or if Landlord estimates that the repair will take 6 months or less, then, Landlord shall
promptly repair the Premises excluding the improvements installed by Tenant or by Landlord and paid
by Tenant, subject to delays arising from the collection of insurance proceeds from Force Majeure
events. Tenant at Tenant’s expense shall promptly perform, subject to delays arising from the
collection of insurance proceeds, or from Force Majeure events, all repairs or restoration not
required to be done by Landlord and shall promptly re-enter the Premises and commence doing
business in accordance with this Lease.

(c) Notwithstanding the foregoing, either party may terminate this Lease if the Premises are
damaged during the last 9 months of the Lease Term and Tenant has not exercised its option to
renew, as applicable (as hereinafter described in Addendum 3), and Landlord reasonably estimates
that it will take more than one month to repair such damage. Base Rent and Operating Expenses shall
be abated for the period of repair and restoration in the proportion which the area of the
Premises, if any, which is not usable by Tenant bears to the total area of the Premises. Unless
Tenant has terminated the Lease pursuant to this Section 15, such abatement shall be the sole
remedy of Tenant.

(d) If Landlord shall be obligated to repair or restore the Premises under the provisions of
this Section 15 and shall not complete the restoration within the estimated or required time as
provided above, Tenant may, at its election, give written notice to Landlord and to any Lenders of
which Tenant has actual notice of Tenant’s election to use the proceeds of such insurance to
perform the necessary repairs or restorations of the Premises. If Tenant gives such notice to
Landlord and such Lenders and such repair or restoration is not commenced within 60 days after
receipt of such notice, then Tenant shall be entitled to take over the repairs or restoration and
to use all available insurance proceeds for such purposes. If Landlord or a lender completes the
repair or restoration of the Premises within 60 days after receipt of such notice, Tenant shall not
have such right. “Commence” as used in this Paragraph shall mean either the unconditional
authorization of the preparation of the required plans, or the beginning of the actual work on the
Premises, whichever first occurs.

(e) In the event Landlord fails to perform any terms, covenants, conditions, or warranties
under this Lease or under applicable law, beyond the applicable cure period, then Tenant shall have
the right, but not the obligation to make the necessary and applicable repairs or to take the
necessary appropriate action, on behalf of Landlord, and Landlord shall credit Tenant’s Base Rent
for the cost of such repairs.

(f) Tenant hereby waives the provisions of California Civil Code Sections 1932(2) and 1933(4),
to the extent that they are inconsistent with the provisions of this Paragraph.

16. Condemnation.

(a) Immediately upon obtaining knowledge of the institution of any proceeding which may result
in the transfer of title to all or a portion of the Premises by condemnation or other eminent
domain proceeding, or by reason of any agreement with any potential condemning authority in
settlement of or under any such proceedings (each, a “Taking”), Tenant shall notify Landlord
thereof and Landlord (and Landlord’s Lender, if any) shall be entitled to participate in any such
proceeding at Tenant’s expense. Landlord, immediately upon obtaining knowledge of the institution
of any proceeding which may result in Taking, shall notify Tenant thereof and Tenant shall have the
right to participate in such proceeding at it own expense. Tenant hereby irrevocably assigns to
Landlord any award or payment in respect of any Taking, except that Tenant does not assign to
Landlord any award or payment on account of Tenant’s Trade Fixtures or other tangible personal
property, moving expenses and similar claims which do not decrease the award to Landlord, and
Tenant shall have a right to make a separate claim therefore against the condemning authority.

(b) If (i) the entire Premises or (ii) at least 15% of the floor area of the Premises, the
loss of which, in any case, even after Restoration (meaning the restoration of the Premises as
nearly as possible to the same physical condition as existed immediately prior to the Taking)
would, in Tenant’s reasonable business judgment, be substantially and materially adverse to the
business operations of Tenant, or (iii) access to the Premises that exists as of the date hereof
(unless sufficient access can be available after Restoration at a reasonable cost to Tenant in
excess of the “Net Award”, being the entire award paid by reason of the Taking, less actual and
reasonable costs incurred in collecting same, or (iv) the number of parking spaces that would, if
eliminated, reduce the total number required by Legal Requirements (unless sufficient replacement
parking spaces can be provided on the Premises to satisfy such Legal Requirements at a reasonable
cost to Tenant in excess of the Net Award), shall be subject of a Taking, then Tenant shall have
the right, exercisable within thirty (30) days after the Taking has occurred, to serve Tenant’s
Termination Notice of its intention to terminate this Lease the Termination Date, which shall be no
sooner than thirty (30) days after the date of Tenant’s Termination Notice and not later than
ninety (90) days after the Tenant’s Termination Notice.

In the event that Tenant shall timely serve Tenant’s Termination Notice upon Landlord, this
Lease and the Lease Term hereof shall terminate on the Termination Date.

(c) In the event of any Taking of part of the Premises which does not result in a termination
of this Lease, the Net Award of such Taking shall be retained by Landlord, unless if separately
awarded to Tenant, and, promptly after such Taking, Tenant shall commence and diligently continue
to perform the Restoration whether or not the Net Award shall be sufficient to do so.

Upon the payment to Landlord of the Net Award of the Taking which falls within the provisions
of this subparagraph (c), Landlord (and Landlord’s Lender, if any) shall, to the extent received,
make that portion of the Net Award equal to the cost of Restoration (the “Restoration Award”)
available to Tenant for Restoration, the balance remaining (the “Net Surplus Award”) shall be the
property of Landlord, and shall be applied, at Landlord’s option, as follows:

(i) The Net Surplus Award shall be retained by Landlord, in which event the
Base Rent becoming due after Landlord receives the Net Surplus Award, but exclusive
of any extended Term for which Tenant had not exercised its extension option as of
the date Tenant received notice of such Taking, shall be reduced by an amount which
bears the same proportion to the Base Rent payable immediately prior to such Taking
as the Fair Market Rent (as defined in Addendum 3, Paragraph g hereto) of the
portion of the Premises so taken shall bear to the Fair Market Rent of the whole of
the Premises immediately prior to such Taking.

(ii) Tenant shall receive that portion of the Net Surplus Award equal to the
present value (calculated at a discount rate of nine percent (9%) of the reductions
in the Base Rent, exclusive of any extended Terms for which Tenant had not exercised
its extension option as of the date Tenant received notice of such Taking, that
would have occurred had Landlord elected to apply the Net Surplus Award under
subparagraph (i) above; that portion of the Net Surplus Award in excess of the
amount so received by Tenant shall be retained by Landlord; and the Base Rent shall
not be reduced.

(d) Except with respect to an award or payment to which Tenant is entitled pursuant to the
foregoing provisions of this Paragraph no agreement with any condemning authority in settlement of
or under threat of any condemnation or other eminent domain proceedings shall be made by either
Landlord or Tenant without the written consent of the other, which consent shall not be reasonably
withheld, conditioned or delayed provided such award or payment is applied in accordance with this
Lease.

(e) Notwithstanding anything to the contrary set forth herein after a Taking which does not
result in the termination of this Lease, the Monthly Base Rent and Operating Expense Payments and
other charges, if any, due hereunder shall be reduced in the same proportion as the rentable floor
area of the Premises taken bears to the original rentable floor area of the Premises prior to such
taking.

17. Assignment and Subletting. Without Landlord’s prior written consent, which Landlord shall
not unreasonably withhold, condition or delay, Tenant shall not assign this Lease or sublease the
Premises or any part thereof or mortgage, pledge, or hypothecate its leasehold interest or grant
any concession or license within the Premises and any attempt to do any of the foregoing shall be
void and of no effect. For purposes of this paragraph, a transfer of the ownership interests
controlling Tenant shall be deemed an assignment of this Lease unless such ownership interests are
publicly traded or unless such transfers do not result in a loss of such control. Notwithstanding
the above, Tenant may assign or sublet the Premises, or any part thereof, to any entity controlling
Tenant, controlled by Tenant or under common control with Tenant (a “Tenant Affiliate”), without
the prior written consent of Landlord, but upon notice to Landlord, and provided that any Tenant
Affiliate which is assignee assumes in writing all of Tenant’s obligations under the Lease and any
Tenant Affiliate which is a subtenant executes a sublease which complies with the requirements
below. Tenant shall reimburse Landlord for all of Landlord’s reasonable out-of-pocket expenses in
connection with any assignment or sublease.

It shall be reasonable for the Landlord to withhold its consent to any assignment or sublease
in any of the following instances: (i) an Event of Default has occurred and is continuing that
would not be cured upon the proposed sublease or assignment; (ii) the assignee or sublessee does
not have a net worth calculated according to generally accepted accounting principles at least
equal to $50 million immediately prior to such assignment or sublease; (iii) the intended use of
the Premises by the assignee or sublessee is not reasonably satisfactory to Landlord; (iv) the
identity or business reputation of the assignee or sublessee will, in the good faith judgment of
Landlord, tend to damage the goodwill or reputation of the Project; (v) in the case of a sublease,
the subtenant has not acknowledged that the Lease controls over any inconsistent provision in the
sublease; or (vi) the proposed assignee or sublessee is a governmental agency. Tenant and Landlord
acknowledge that each of the foregoing criteria is reasonable as of the date of execution of this
Lease. The foregoing criteria shall not exclude any other reasonable basis for Landlord to refuse
its consent to such assignment or sublease. Any approved assignment or sublease shall be expressly
subject to the terms and conditions of this Lease. Tenant shall provide to Landlord all
information concerning the assignee or sublessee as Landlord may request.

Notwithstanding any assignment or subletting, Tenant and any guarantor or surety of Tenant’s
obligations under this Lease shall at all times remain fully responsible and liable for the payment
of the rent and for compliance with all of Tenant’s other obligations under this Lease (regardless
of whether Landlord’s approval has been obtained for any such assignments or sublettings). In the
event that the rent due and payable by a sublessee or assignee (or a combination of the rental
payable under such sublease or assignment plus any bonus or other consideration therefor or
incident thereto) exceeds the rental payable under this Lease (prorated if less than 100% of the
Premises are subleased or assigned), then Tenant shall be bound and obligated to pay Landlord as
additional rent hereunder 50% of all such excess rental and other excess consideration within 10
days following receipt thereof by Tenant.

If this Lease be assigned or if the Premises be subleased (whether in whole or in part) or in
the event of the mortgage, pledge, or hypothecation of Tenant’s leasehold interest or grant of any
concession or license within the Premises or if the Premises be occupied in whole or in part by
anyone other than Tenant, then upon a default by Tenant hereunder Landlord may collect rent from
the assignee, sublessee, mortgagee, pledgee, party to whom the leasehold interest was hypothecated,
concessionee or licensee or other occupant and, except to the extent set forth in the preceding
paragraph, apply the amount collected to the next rent payable hereunder; and all such rentals
collected by Tenant shall be held in trust for Landlord and immediately forwarded to Landlord. No
such transaction or collection of rent or application thereof by Landlord, however, shall be deemed
a waiver of these provisions or a release of Tenant from the further performance by Tenant of its
covenants, duties, or obligations hereunder.

18. Indemnification. Except for the gross negligence or willful misconduct of Landlord, its
agents, employees or contractors, and to the extent permitted by law, Tenant agrees to indemnify,
defend and hold harmless Landlord, and Landlord’s members and their respective agents, employees
and contractors and any Lender, from and against any and all losses, liabilities, damages, costs
and expenses (including attorneys’ fees) resulting from claims by third parties for injuries to any
person and damage to or theft or misappropriation or loss of property occurring in or about the
Premises and arising from the use and occupancy of the Premises or from any activity, work, or
thing done, permitted or suffered by Tenant in or about the Premises or due to any other act or
omission of Tenant, its subtenants, assignees, invitees, employees, contractors and agents. The
furnishing of insurance required hereunder shall not be deemed to limit Tenant’s obligations under
this Paragraph 18.

Except for the gross negligence or willful misconduct of Tenant, its agents, employees or
contractors, and to the extent permitted by law, Landlord agrees to indemnify, defend and hold
harmless Tenant, and Tenant’s shareholders, directors, officers, agents, employees and contractors,
from and against any and all losses, liabilities, damages, costs and expenses (including
attorneys’ fees) resulting from claims by third parties for injuries to any person and damage to or
loss of property occurring in or about the Premises or the Project resulting from the grossly
negligent or willful acts or omissions of Landlord.

The provisions of this paragraph shall survive termination of the Lease with respect to events
occurring prior to such termination.

19. Inspection and Access. Landlord and its agents, representatives, and contractors may
enter the Premises at any reasonable time to inspect the Premises and to make such repairs as may
be required or permitted pursuant to this Lease and for any other business purpose. Landlord and
Landlord’s representatives may enter the Premises during business hours for the purpose of showing
the Premises to prospective purchasers and, during the last two years of the Lease Term, to
prospective tenants. Landlord may erect a suitable sign on the Premises stating the Premises are
available to let or that the Premises is available for sale. Landlord may grant easements, make
public dedications, designate common areas and create restrictions on or about the Premises,
provided that no such easement, dedication, designation or restriction materially interferes with
Tenant’s use or occupancy of the Premises. At Landlord’s request, Tenant shall execute such
instruments as may be necessary for such easements, dedications or restrictions.

20. Quiet Enjoyment. Upon payment by Tenant of the rent for the Premises and the observance
and performance of all of the covenants, conditions and provisions on Tenant’s part to be observed
and performed under this Lease, Tenant shall have quiet possession of the Premises for the entire
term hereof subject to all of the provisions of this Lease. If Tenant shall not be in default
beyond any applicable grace period provided herein, Tenant shall peaceably and quietly occupy and
enjoy the full possession and use of the Premises and the use of the Common Areas.

21. Surrender. Upon expiration of the Lease Term or earlier termination of the Lease, Tenant
shall surrender the Premises to Landlord in the same condition as received, broom clean, ordinary
wear and tear and casualty loss and condemnation covered by Paragraphs 15 and 16, and Tenant’s
removal or non-removal of Tenant-Made Alterations pursuant to the provisions of Paragraph 12
excepted. Any Trade Fixtures, Tenant-Made Alterations and property not so removed by Tenant as
permitted or required herein shall be deemed abandoned and may be stored, removed, and disposed of
by Landlord at Tenant’s expense, and Tenant waives all claims against Landlord for any damages
resulting from Landlord’s retention and disposition of such property. All obligations of Tenant
hereunder not fully performed as of the termination of the Lease Term shall survive the termination
of the Lease Term, including without limitation, indemnity obligations, payment obligations with
respect to Operating Expenses, and obligations concerning the condition and repair of the Premises.

22. Holding Over. If Tenant retains possession of the Premises after the expiration of the
Lease Term, unless otherwise agreed in writing, such possession shall be subject to immediate
termination by Landlord at any time, and all of the other terms and provisions of this Lease
(excluding any expansion or renewal option or other similar right or option) shall be applicable
during such holdover period, except that Tenant shall pay Landlord from time to time, upon demand,
as Base Rent for the holdover period, an amount equal to double the Base Rent in effect on the
termination date, computed on a monthly basis for each month or part thereof during such holding
over. All other payments shall continue under the terms of this Lease. In addition, Tenant shall
be liable for all damages incurred by Landlord as a result of such holding over. No holding over
by Tenant, whether with or without consent of Landlord, shall operate to extend this Lease except
as otherwise expressly provided, and this Paragraph 22 shall not be construed as consent for Tenant
to retain possession of the Premises. For purposes of this Paragraph 22, “possession of the
Premises” shall continue until, among other things, Tenant has delivered all keys to the Premises
to Landlord, Landlord has complete and total dominion and control over the Premises, and Tenant has
completely fulfilled all obligations required of it upon termination of the Lease as set forth in
this Lease, including, without limitation, those concerning the condition and repair of the
Premises.

23. Events of Default. Each of the following events shall be an event of default (“Event of
Default”) by Tenant under this Lease:

(i) Tenant shall fail to pay any installment of Base Rent or any other payment
required herein when due, and such failure shall continue for a period of 10 days
from the date of written notice thereof.

(ii) Tenant or any guarantor or surety of Tenant’s obligations hereunder shall
(A) make a general assignment for the benefit of creditors; (B) commence any case,
proceeding or other action seeking to have an order for relief entered on its behalf
as a debtor or to adjudicate it a bankrupt or insolvent, or seeking reorganization,
arrangement, adjustment, liquidation, dissolution or composition of it or its debts
or seeking appointment of a receiver, trustee, custodian or other similar official
for it or for all or of any substantial part of its property (collectively a
“proceeding for relief”); (C) become the subject of any proceeding for relief which
is not dismissed within 60 days of its filing or entry; or (D) die or suffer a legal
disability (if Tenant, guarantor, or surety is an individual) or be dissolved or
otherwise fail to maintain its legal existence (if Tenant, guarantor or surety is a
corporation, partnership or other entity).

(iii) Any insurance required to be maintained by Tenant pursuant to this Lease
shall be cancelled or terminated or shall expire or shall be reduced or materially
changed, except, in each case, as permitted in this Lease.

(iv) Tenant shall abandon or vacate the Premises or fail to continuously
operate its business at the Premises for the permitted use set forth herein, whether
or not Tenant is in monetary or other default under this Lease. Notwithstanding
anything contained herein to the contrary, Tenant’s abandoning, vacating, or failing
to continuously operate its business at, the Premises shall not constitute an Event
of Default if, prior to vacating, abandoning, or ceasing to continuously operate its
business at the Premises, Tenant has made arrangements reasonably acceptable to
Landlord to (a) insure that the insurance for the Premises will not be voided or
cancelled with respect to the Premises as a result of such vacancy, abandonment, or
ceasing of operations, (b) insure that the Premises are reasonably secured from
theft and vandalism, and (c) insure that the Premises will be properly maintained
after such vacation. Tenant shall inspect the Premises at least once each month and
report monthly in writing to Landlord in the event the condition of the Premises has
materially changed.

(v) Tenant shall attempt or there shall occur any assignment, subleasing or
other transfer of Tenant’s interest in or with respect to this Lease except as
otherwise permitted in this Lease.

(vi) Tenant shall fail to discharge any lien placed upon the Premises in
violation of this Lease within 30 days after any such lien or encumbrance is filed
against the Premises.

(vii) Tenant shall fail to comply with any provision of this Lease other than
those specifically referred to in this Paragraph 23, and except as otherwise
expressly provided herein, such default shall continue for more than 30 days after
Landlord shall have given Tenant written notice of such default, or if performance
is not possible within such period, any failure of Tenant to commence performance
within such period and to diligently prosecute such performance to completion.

24. Landlord’s Remedies. Upon each occurrence of an Event of Default and so long as such
Event of Default shall be continuing, Landlord may at any time thereafter at its election:
 terminate this Lease or Tenant’s right of possession, (but Tenant shall remain liable as
hereinafter provided) and/or pursue any other remedies at law or in equity. Upon the termination
of this Lease or termination of Tenant’s right of possession, it shall be lawful for Landlord,
without formal demand or notice of any kind, to re-enter the Premises by summary dispossession
proceedings or any other action or proceeding authorized by law and to remove Tenant and all
persons and property therefrom. If Landlord re-enters the Premises, Landlord shall have the right
to keep in place and use, or remove and store, all of the furniture, fixtures and equipment at the
Premises.

Except as otherwise provided in the next paragraph, if Tenant breaches this Lease and abandons
the Premises prior to the end of the term hereof, or if Tenant’s right to possession is terminated
by Landlord because of an Event of Default by Tenant under this Lease, this Lease shall terminate.
Upon such termination, Landlord may recover from Tenant the following, as provided in Section
1951.2 of the Civil Code of California: (i) the worth at the time of award of the unpaid Base Rent
and other charges under this Lease that had been earned at the time of termination; (ii) the worth
at the time of award of the amount by which the reasonable value of the unpaid Base Rent and other
charges under this Lease which would have been earned after termination until the time of award
exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; (iii)
the worth at the time of the award by which the reasonable value of the unpaid Base Rent and other
charges under this Lease for the balance of the term of this Lease after the time of award exceeds
the amount of such rental loss that Tenant proves could have been reasonably avoided; and (iv) any
other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s
failure to perform its obligations under this Lease or that in the ordinary course of things would
be likely to result therefrom. As used herein, the following terms are defined: (a) the “worth at
the time of award” of the amounts referred to in Sections (i) and (ii) is computed by allowing
interest at the lesser of 18 percent per annum or the maximum lawful rate. The “worth at the time
of award” of the amount referred to in Section (iii) is computed by discounting such amount at the
discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one percent;
(b) the “time of award” as used in clauses (i), (ii), and (iii) above is the date on which judgment
is entered by a court of competent jurisdiction; (c) The “reasonable value” of the amount referred
to in clause (ii) above is computed by determining the mathematical product of (1) the “reasonable
annual rental value” (as defined herein) and (2) the number of years, including fractional parts
thereof, between the date of termination and the time of award. The “reasonable value” of the
amount referred to in clause (iii) is computed by determining the mathematical product of (1) the
annual Base Rent and other charges under this Lease and (2) the number of years including
fractional parts thereof remaining in the balance of the term of this Lease after the time of
award.

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

Exercise by Landlord of any one or more remedies hereunder granted or otherwise available
shall not be deemed to be an acceptance of surrender of the Premises and/or a termination of this
Lease by Landlord, whether by agreement or by operation of law, it being understood that such
surrender and/or termination can be effected only by the written agreement of Landlord and Tenant.
Any law, usage, or custom to the contrary notwithstanding, Landlord shall have the right at all
times to enforce the provisions of this Lease in strict accordance with the terms hereof; and the
failure of Landlord at any time to enforce its rights under this Lease strictly in accordance with
same shall not be construed as having created a custom in any way or manner contrary to the
specific terms, provisions, and covenants of this Lease or as having modified the same. Tenant and
Landlord further agree that forbearance or waiver by Landlord to enforce its rights pursuant to
this Lease or at law or in equity shall not be a waiver of Landlord’s right to enforce one or more
of its rights in connection with any subsequent default. A receipt by Landlord of rent or other
payment with knowledge of the breach of any covenant hereof shall not be deemed a waiver of such
breach, and no waiver by Landlord of any provision of this Lease shall be deemed to have been made
unless expressed in writing and signed by Landlord. To the greatest extent permitted by law,
Tenant waives the service of notice of Landlord’s intention to re-enter as provided for in any
statute, or to institute legal proceedings to that end, and also waives all right of redemption in
case Tenant shall be dispossessed by a judgment or by warrant of any court or judge. The terms
“enter,” “re-enter,” “entry” or “re-entry,” as used in this Lease, are not restricted to their
technical legal meanings. Any reletting of the Premises shall be on such terms and conditions as
Landlord in its sole discretion may determine (including without limitation a term different than
the remaining Lease Term, rental concessions, alterations and repair of the Premises, lease of less
than the entire Premises to any tenant and leasing any or all other portions of the Project before
reletting the Premises). Landlord shall not be liable, nor shall Tenant’s obligations hereunder be
diminished because of, Landlord’s failure to relet the Premises or collect rent due in respect of
such reletting.

25. Tenant’s Remedies/Limitation of Liability. Landlord shall not be in default hereunder
unless Landlord fails to perform any of its obligations hereunder within 30 days after written
notice from Tenant specifying such failure (unless such performance will, due to the nature of the
obligation, require a period of time in excess of 30 days, then after such period of time as is
reasonably necessary so long as Landlord commences performing within said period and diligently
prosecutes such performance to completion). Upon such failure Tenant shall have the option but not
the obligation to cause such repair and deduct such reasonable amount from the Base Rent.
Notwithstanding anything to the contrary contained herein, in the event of an emergency situation
which effects the roof or structural integrity of the Premises, Landlord shall use its best efforts
to repair such damage within five (5) days of Tenant’s written notice of such event. In the event
of an emergency (any event that in Tenant’s reasonable opinion poses a potential threat to life
and/or property), and/or in the event that Landlord shall fail to perform any of Landlord’s
responsibilities within the applicable cure period, then Tenant shall have the right, but not the
obligation to make the necessary and appropriate repairs, or to take the appropriate action on
behalf of Landlord, and Landlord shall promptly reimburse Tenant the full cost of such repairs or
action. If Landlord shall fail to fully reimburse Tenant for such costs, Tenant may, but shall not
be required to deduct such amounts from any amounts owing or to become owing from Tenant to
Landlord. All obligations of Landlord hereunder shall be construed as covenants, not conditions;
and, except as may be otherwise expressly provided in this Lease, Tenant may not terminate this
Lease for breach of Landlord’s obligations hereunder. All obligations of Landlord under this Lease
will be binding upon Landlord only during the period of its ownership of the Premises and not
thereafter. The term “Landlord” in this Lease shall mean only the owner, for the time being of the
Premises, and in the event of the transfer by such owner of its interest in the Premises, such
owner shall thereupon be released and discharged from all obligations of Landlord thereafter
accruing, it being understood that Landlord shall not be released from any obligations accruing
prior to such transfer unless such obligations have been assumed in writing by Landlord’s
successor, but such obligations shall be binding during the Lease Term upon each new owner for the
duration of such owner’s ownership. Any liability of Landlord under this Lease shall be limited
solely to its interest in the Premises, and in no event shall any personal liability be asserted
against Landlord or any of Landlord’s partners in connection with this Lease nor shall any recourse
be had to any other property or assets of Landlord or any of Landlord’s partners.

26. Intentionally Deleted.

27. Subordination. This Lease and Tenant’s interest and rights hereunder are and shall be
subject and subordinate at all times to the lien of any mortgage, now existing or hereafter created
on or against the Project or the Premises, and all amendments, restatements, renewals,
modifications, consolidations, refinancing, assignments and extensions thereof, without the
necessity of any further instrument or act on the part of Tenant. Tenant agrees, at the election
of the holder of any such mortgage, to attorn to any such holder. Tenant agrees upon demand to
execute, acknowledge and deliver such instruments, confirming such subordination and such
instruments of attornment as shall be requested by any such holder. Tenant hereby appoints
Landlord attorney in fact for Tenant irrevocably (such power of attorney being coupled with an
interest) to execute, acknowledge and deliver any such instrument and instruments for and in the
name of the Tenant and to cause any such instrument to be recorded. Notwithstanding the foregoing,
any such holder may at any time subordinate its mortgage to this Lease, without Tenant’s consent,
by notice in writing to Tenant, and thereupon this Lease shall be deemed prior to such mortgage
without regard to their respective dates of execution, delivery or recording and in that event such
holder shall have the same rights with respect to this Lease as though this Lease had been executed
prior to the execution, delivery and recording of such mortgage and had been assigned to such
holder. The term “mortgage” whenever used in this Lease shall be deemed to include deeds of trust,
security assignments and any other encumbrances, and any reference to the “holder” of a mortgage
shall be deemed to include the beneficiary under a deed of trust.

Notwithstanding the foregoing paragraph, Tenant shall not be obligated to subordinate the
Lease or its interest therein to any mortgage, deed of trust or ground lease on the Project or the
Premises unless concurrently with such subordination the holder of such mortgage or deed of trust
or the ground lessor under such ground lease upon commercially reasonable terms including, agreeing
not to disturb Tenant’s possession of the Premises under the terms of the Lease in the event such
holder or ground lessor acquires title to the Premises through foreclosure, deed in lieu of
foreclosure or otherwise. Landlord shall use reasonable commercial efforts to obtain, at no cost
to Tenant, a non-disturbance agreement from any such holder or ground lessor existing as of the
Commencement Date for the benefit of Tenant in a commercially reasonable form within 20 days of the
date of this Lease.

28. Mechanic’s Liens. Tenant has no express or implied authority to create or place any lien
or encumbrance of any kind upon, or in any manner to bind the interest of Landlord or Tenant in,
the Premises or to charge the rentals payable hereunder for any claim in favor of any person
dealing with Tenant, including those who may furnish materials or perform labor for any
construction or repairs. Tenant covenants and agrees that it will pay or cause to be paid all sums
legally due and payable by it on account of any labor performed or materials furnished in
connection with any work performed on the Premises and that it will save and hold Landlord harmless
from all loss, cost or expense based on or arising out of asserted claims or liens against the
leasehold estate or against the interest of Landlord in the Premises or under this Lease. Tenant
shall give Landlord immediate written notice of the placing of any lien or encumbrance against the
Premises and cause such lien or encumbrance to be discharged within 30 days of the filing or
recording thereof; provided, however, Tenant may contest such liens or encumbrances as long as such
contest prevents foreclosure of the lien or encumbrance and Tenant causes such lien or encumbrance
to be bonded or insured over in a manner satisfactory to Landlord within such 30 day period.

29. Estoppel Certificates. Tenant agrees, from time to time, within 10 days after request of
Landlord, to execute and deliver to Landlord, or Landlord’s designee, any estoppel certificate
requested by Landlord, stating that this Lease is in full force and effect, the date to which rent
has been paid, that Landlord is not in default hereunder (or specifying in detail the nature of
Landlord’s default), the termination date of this Lease and such other matters pertaining to this
Lease as may be requested by Landlord. Tenant’s obligation to furnish each estoppel certificate in
a timely fashion is a material inducement for Landlord’s execution of this Lease. No cure or grace
period provided in this Lease shall apply to Tenant’s obligations to timely deliver an estoppel
certificate. Tenant hereby irrevocably appoints Landlord as its attorney in fact to execute on its
behalf and in its name any such estoppel certificate if Tenant fails to execute and deliver the
estoppel certificate within 10 days after Landlord’s written request thereof.

30. Environmental Requirements. Except for Hazardous Material (as defined below) contained in
products used by Tenant in de minimis quantities for ordinary cleaning and office purposes and
equipment maintenance, Tenant shall not permit or cause any party to bring any Hazardous Material
upon the Premises or transport, store, use, generate, manufacture or release any Hazardous Material
in or about the Premises without Landlord’s prior written consent. Tenant, at its sole cost and
expense, shall operate its business in the Premises in strict compliance with all Environmental
Requirements and shall remediate in a manner satisfactory to Landlord any Hazardous Materials
released on or from the Premises or the Project by Tenant, its agents, employees, contractors,
subtenants or invitees. Tenant shall complete and certify to disclosure statements as requested by
Landlord from time to time relating to Tenant’s transportation, storage, use, generation,
manufacture or release of Hazardous Materials on the Premises. The term “Environmental
Requirements” means all applicable present and future statutes, regulations, ordinances, rules,
codes, judgments, orders or other similar enactments of any governmental authority or agency
regulating or relating to health, safety, or environmental conditions on, under, or about the
Premises or the environment, including without limitation, the following: the Comprehensive
Environmental Response, Compensation and Liability Act; the Resource Conservation and Recovery Act;
and all state and local counterparts thereto, and any regulations or policies promulgated or issued
thereunder. The term “Hazardous Materials” means and includes any substance, material, waste,
pollutant, or contaminant listed or defined as hazardous or toxic, under any Environmental
Requirements, asbestos and petroleum, including crude oil or any fraction thereof, natural gas
liquids, liquefied natural gas, or synthetic gas usable for fuel (or mixtures of natural gas and
such synthetic gas). As defined in Environmental Requirements, Tenant is and shall be deemed to be
the “operator” of Tenant’s “facility” and the “owner” of all Hazardous Materials brought on the
Premises by Tenant, its agents, employees, contractors or invitees, and the wastes, by-products, or
residues generated, resulting, or produced therefrom.

Tenant shall indemnify, defend, and hold Landlord harmless from and against any and all losses
(including, without limitation, diminution in value of the Premises or the Project and loss of
rental income from the Premises or the Project), claims, demands, actions, suits, damages
(including, without limitation, punitive damages), expenses (including, without limitation,
remediation, removal, repair, corrective action, or cleanup expenses), and costs (including,
without limitation, actual attorneys’ fees, consultant fees or expert fees and including, without
limitation, removal or management of any asbestos brought into the property by Tenant, its agents,
employees, contractors, subtenants, assignees or invitees or disturbed by Tenant, its agents,
employees, contractors, subtenants, assignees or invitees in breach of the requirements of this
Paragraph 30, regardless of whether such removal or management is required by law) which are
brought or recoverable against, or suffered or incurred by Landlord as a result of any release of
Hazardous Materials for which Tenant is obligated to remediate as provided above or any other
breach of the requirements under this Paragraph 30 by Tenant, its agents, employees, contractors,
subtenants, assignees or invitees, regardless of whether Tenant had knowledge of such
noncompliance. The obligations of Tenant under this Paragraph 30 shall survive any termination of
this Lease.

Landlord shall have access to, and a right to perform inspections and tests of, the Premises
to determine Tenant’s compliance with Environmental Requirements, its obligations under this
Paragraph 30, or the environmental condition of the Premises. Access shall be granted to Landlord
upon Landlord’s prior notice to Tenant and at such times so as to minimize, so far as may be
reasonable under the circumstances, any disturbance to Tenant’s operations. Such inspections and
tests shall be conducted at Landlord’s expense, unless such inspections or tests reveal that Tenant
has not complied with any Environmental Requirement, in which case Tenant shall reimburse Landlord
for the reasonable cost of such inspection and tests. Landlord’s receipt of or satisfaction with
any environmental assessment in no way waives any rights that Landlord holds against Tenant.

Landlord represents and warrants that except for information contained in the Phase I
Environmental Assessment Reports prepared by LOR Environmental, Inc., and delivered to Tenant,
Landlord, to Landlord’s knowledge without further inquiry, is unaware of any environmental
conditions affecting the Premises.

Notwithstanding anything to the contrary in this Paragraph 30, Tenant shall have no liability
of any kind to Landlord or any other party and Landlord shall indemnify Tenant as to Hazardous
Materials on the Premises caused or permitted by Landlord, its agents, employees, contractors or
invitees.

31. Rules and Regulations. Tenant shall, at all times during the Lease Term and any extension
thereof, comply with all reasonable rules and regulations at any time or from time to time
established by Landlord covering use of the Premises and the Project. The current rules and
regulations are attached hereto. In the event of any conflict between said rules and regulations
and other provisions of this Lease, the other terms and provisions of this Lease shall control.
Landlord shall not have any liability or obligation for the breach of any rules or regulations by
other tenants in the Project.

32. Security Service. Tenant acknowledges and agrees that, while Landlord may patrol the
Project, Landlord is not providing any security services with respect to the Premises and that
Landlord shall not be liable to Tenant for, and Tenant waives any claim against Landlord with
respect to, any loss by theft or any other damage suffered or incurred by Tenant in connection with
any unauthorized entry into the Premises or any other breach of security with respect to the
Premises.

33. Force Majeure. Except for monetary obligations, neither Landlord nor Tenant shall be held
responsible for delays in the performance of its obligations hereunder when caused by strikes,
lockouts, labor disputes, acts of God, inability to obtain labor or materials or reasonable
substitutes therefor, governmental restrictions, governmental regulations, governmental controls,
delay in issuance of permits, enemy or hostile governmental action, acts of terrorism, civil
commotion, fire or other casualty, and other causes beyond the reasonable control of Landlord or
Tenant (“Force Majeure”).

34. Entire Agreement. This Lease constitutes the complete agreement of Landlord and Tenant
with respect to the subject matter hereof. No representations, inducements, promises or
agreements, oral or written, have been made by Landlord or Tenant, or anyone acting on behalf of
Landlord or Tenant, which are not contained herein, and any prior agreements, promises,
negotiations, or representations are superseded by this Lease. This Lease may not be amended
except by an instrument in writing signed by both parties hereto.

35. Severability. If any clause or provision of this Lease is illegal, invalid or
unenforceable under present or future laws, then and in that event, it is the intention of the
parties hereto that the remainder of this Lease shall not be affected thereby. It is also the
intention of the parties to this Lease that in lieu of each clause or provision of this Lease that
is illegal, invalid or unenforceable, there be added, as a part of this Lease, a clause or
provision as similar in terms to such illegal, invalid or unenforceable clause or provision as may
be possible and be legal, valid and enforceable.

36. Brokers. Tenant represents and warrants that it has dealt with no broker, agent or other
person in connection with this transaction and that no broker, agent or other person brought about
this transaction, other than the broker, if any, set forth on the first page of this Lease, and
Tenant agrees to indemnify and hold Landlord harmless from and against any claims by any other
broker, agent or other person claiming a commission or other form of compensation by virtue of
having dealt with Tenant with regard to this leasing transaction. Landlord hereby acknowledges and
agrees that the broker referenced on Page One of this Lease shall be entitled to a leasing
commission from Landlord by virtue of this Lease, which leasing commission shall be deemed earned
and shall be paid by Landlord to said broker in accordance with, and subject to the terms of, a
separate written agreement.

37. Miscellaneous.

(a) Any payments or charges due from Tenant to Landlord hereunder shall be considered rent
for all purposes of this Lease.

(b) If and when included within the term “Tenant,” as used in this instrument, there is more
than one person, firm or corporation, each shall be jointly and severally liable for the
obligations of Tenant.

(c) All notices required or permitted to be given under this Lease shall be in writing and
shall be sent by registered or certified mail, return receipt requested, or by a reputable national
overnight courier service, postage prepaid, or by hand delivery addressed to the parties at their
addresses below. Either party may by notice given aforesaid change its address for all subsequent
notices. Except where otherwise expressly provided to the contrary, notice shall be deemed given
upon delivery.

(d) Except as otherwise expressly provided in this Lease or as otherwise required by law,
Landlord’s right to withhold any consent or approval shall not be unreasonably withheld or delayed.

(e) All payments of monetary sums due by Tenant to Landlord hereunder, including, but not
limited to, Base Rent and payments of Operating Expenses, shall be deemed to be “rent”.

(f) Neither this Lease nor a memorandum of lease shall be filed by or on behalf of Tenant in
any public record. Landlord may prepare and file, and upon request by Landlord Tenant will
execute, a memorandum of lease.

(g) The normal rule of construction to the effect that any ambiguities are to be resolved
against the drafting party shall not be employed in the interpretation of this Lease or any
exhibits or amendments hereto.

(h) The submission by Landlord to Tenant of this Lease shall have no binding force or effect,
shall not constitute an option for the leasing of the Premises, nor confer any right or impose any
obligations upon either party until execution of this Lease by both parties.

(i) Words of any gender used in this Lease shall be held and construed to include any other
gender, and words in the singular number shall be held to include the plural, unless the context
otherwise requires. The captions inserted in this Lease are for convenience only and in no way
define, limit or otherwise describe the scope or intent of this Lease, or any provision hereof, or
in any way affect the interpretation of this Lease.

(j) Any amount not paid by Tenant within 10 days after its due date in accordance with the
terms of this Lease shall bear interest from such due date until paid in full at the lesser of the
highest rate permitted by applicable law or 10 percent per year. It is expressly the intent of
Landlord and Tenant at all times to comply with applicable law governing the maximum rate or amount
of any interest payable on or in connection with this Lease.  If applicable law is ever judicially
interpreted so as to render usurious any interest called for under this Lease, or contracted for,
charged, taken , reserved, or received with respect to this Lease, then it is Landlord’s and
Tenant’s express intent that all excess amounts theretofore collected by Landlord be credited on
the applicable obligation (or, if the obligation has been or would thereby be paid in full,
refunded to Tenant), and the provisions of this Lease immediately shall be deemed reformed and the
amounts thereafter collectible hereunder reduced, without the necessity of the execution of any new
document, so as to comply with the applicable law, but so as to permit the recovery of the fullest
amount otherwise called for hereunder.   

(k) Construction and interpretation of this Lease shall be governed by the laws of the State
of California, excluding any principles of conflicts of laws.

(l) Time is of the essence as to the performance of Tenant’s obligations under this Lease.

(m) All exhibits and addenda attached hereto are hereby incorporated into this Lease and made
a part hereof. In the event of any conflict between such exhibits or addenda and the terms of this
Lease, such exhibits or addenda shall control.

38. Landlord’s Lien/Subordination. Provided Tenant is not in default under the Lease,
Landlord, at the request of Tenant, agrees to subordinate Landlord’s lien, if any, arising under
the Lease against Tenant’s property or any of Tenant’s leased or financed property located on the
Premises and agrees that Tenant’s property or its leased or financed property shall not become part
of the Premises or encumbered by a lien by Landlord regardless of the manner in which the leased or
financed property may be attached or affixed to the Premises. Such subordination shall be required
only if the lender or lessor shall be a bank or other financial institution or the vendor of
Tenant’s equipment or a financing entity related to such vendor and shall be subject to such
conditions as Landlord may reasonably require. Tenant shall reimburse Landlord for all reasonable
out-of-pocket expenses incurred by Landlord in negotiating and executing such agreement with
Tenant’s lender.

39. Limitation of Liability of Trustees, Shareholders, Members and Officers of Landlord. Any
obligation or liability whatsoever of Landlord which may arise at any time under this Lease or any
obligation or liability which may be incurred by it pursuant to any other instrument, transaction,
or undertaking contemplated hereby shall not be personally binding upon, nor shall resort for the
enforcement thereof be had to the property of, its members, trustees, directors, shareholders,
officers, employees or agents, regardless of whether such obligation or liability is in the nature
of contract, tort, or otherwise.

40. Limitation of Liability of Directors, Shareholders, and Officers of Tenant. Any obligation
or liability whatsoever of Tenant, which may arise at any time under this Lease or any obligation
or liability which may be incurred by it pursuant to any other instrument, transaction, or
undertaking contemplated hereby shall not be personally binding upon, nor shall resort for the
enforcement thereof be had to the property of, its directors, shareholders, officers, employees or
agents, regardless of whether such obligation or liability is in the nature of contract, tort, or
otherwise.

ADDENDUM 2

CONSTRUCTION

CONSTRUCTION OF PREMISES

1. Standard Specifications and Final Plans; Change Orders.

(a) Preparation of Final Plans. Landlord shall furnish or perform at Landlord’s sole
cost and expense those items of construction and those improvements (“Landlord
Improvements”) provided for in the Tenant’s Outline Specifications dated May 1, 2007, together
with the addendum thereto (collectively the “Specifications”) attached as Exhibit
B. Landlord shall provide Tenant with final working drawings and specifications for the
Landlord Improvements (the “Final Plans”) which are consistent with the Specifications.
Tenant shall respond promptly to any inquiries by Landlord during the development of the Final
Plans and, to the extent requested by Landlord, shall cooperate with Landlord and Landlord’s
architect in developing the Final Plans. When Landlord requests Tenant to specify details or
layouts, Tenant shall promptly specify same within 20 days thereafter so as not to delay completion
of the Final Plans or the Landlord Improvements. Tenant shall pay to Landlord upon demand all
increased costs incurred by Landlord in completing the Final Plans to the extent such costs are
attributable to any such Tenant-caused delays.

(b) Change Orders. The Specifications define the entire scope of Landlord’s
obligation to construct or provide the Landlord Improvements. Tenant shall not be entitled to
specify or designate any finishes, grades of materials, or other specifications or details of the
construction of the Landlord Improvements which are not specifically provided for in or
contemplated by the Specifications unless requested to do so by Landlord. Subject to this
paragraph, however, Landlord shall make additions or changes to the Specifications requested by
Tenant. If Tenant shall desire any such changes, Tenant shall so advise Landlord in writing (a
"Change Order Request”) as promptly as possible so as not to delay the orderly development
of the Final Plans. All reasonable costs incurred by Landlord in having any Change Order Request
reviewed and evaluated shall be reimbursed by Tenant upon demand. Such costs shall include, but
not be limited to, the reasonable costs of architects, engineers, and consultants in reviewing and
designing any such changes and the cost of contractors in providing cost estimates and
constructability, functionality and product availability analyses. Tenant acknowledges and agrees
that (i) Landlord shall not be obligated to accept any Change Order Request if in the reasonable
judgment of Landlord the requested change would have an adverse effect on the quality, useful life,
value, functionality or costs of operating or maintaining the Landlord Improvements; (ii) Tenant
shall bear all costs and expenses associated with incorporating into the Final Plans and the
Landlord Improvements any Change Order Request accepted by Landlord, including without limitation
an administrative fee to Landlord equal to 10 percent of the increased cost resulting from such
change (and Tenant shall pay such costs to Landlord, in advance as provided below); (iii) Landlord
shall not be obligated to accept the least expensive method of incorporating the requested change
if in the reasonable judgment of Landlord, such method does not incorporate sound construction
practices; (iv) if the Change Order Request affects the roof, slab, structural components or
systems or equipment to be installed within the Landlord Improvements or the future serviceability
of the Landlord Improvements, and the Landlord determines that in order to lease the building to
any subsequent tenant, additional work will have to be done to remove the effect of such change,
the anticipated costs of restoring the Landlord Improvements to the condition it would have been in
but for such change will also be paid in advance by the Tenant as a condition to Tenant’s change,
as provided below; and (v) to the extent Tenant specifies any items which have not been recommended
by Landlord, Tenant assumes full responsibility for their performance. Upon agreement between
Landlord and Tenant on the change that will be incorporated into the Final Plans and Landlord
Improvements as a result of a Change Order Request, and the cost of such change, the Landlord and
Tenant shall execute a change order (a “Change Order”) setting forth the parties’ agreement
as to such terms. Payment of the Change Order cost shall be due from Tenant within 30 days of the
mutual execution of the Change Order.

(c) Approval of Final Plans. Landlord shall submit the Final Plans to Tenant for its
approval and Tenant shall advise Landlord, within 5 days thereafter, of its approval or disapproval
of such Final Plans. Tenant’s right to disapprove the proposed Final Plans (“Objection”)
shall be limited to material inconsistencies with the Specifications and any Change Orders then
entered into, and noncompliance with or violation of applicable laws, codes, ordinances or other
legal requirements. If Tenant shall not make an Objection to the proposed Final Plans or any
element or aspect thereof within the 5 day period set forth above, then such Final Plans or the
portions not objected to by Tenant shall be deemed approved. Resolution of any Objection by Tenant
to the Final Plans shall be governed by Paragraph 3 below.

(d) Commencement of Construction Before Final Plans. Landlord may commence
construction prior to finalization of the Final Plans and Tenant agrees that it shall cooperate
with Landlord in reviewing and approving portions of the Final Plans for different stages or
elements of the work so that construction can proceed on a “fast track” basis. The approval
process for such portions of the Final Plans shall be substantially as set forth above, provided,
however, that any Objection may not be inconsistent with the previously approved portions of the
Final Plans.

(e) Change Orders During Construction. In the event that subsequent to the completion
and approval of the Final Plans, Tenant desires to make a change in the work provided for therein,
the parties shall proceed in accordance with the foregoing provisions relating to changes requested
during the development of the Final Plans.

2. Project Representatives. Landlord hereby designates Brian Hixson to serve as
Landlord’s representative and Tenant hereby designates Paul Galliher to serve as Tenant’s
representative during the design and construction of the Landlord Improvements. Either party may
change its representative by notice to the other party. All communications between Landlord and
Tenant relating to the design and construction of the Initial Improvements shall be forwarded to or
made by such party’s representative. In addition, no Change Order shall be binding on Landlord
unless executed by Landlord’s Representative and no Change Order shall be binding on Tenant unless
executed by Tenant’s Representative.

3. Dispute Resolution.

(a) Conference of Senior Representatives. The parties shall make good faith efforts
to resolve any dispute which may arise under this Addendum in an expedient manner. In the event,
however, that any dispute arises, either party may notify the other party of its intent to invoke
the dispute resolution procedure herein set forth by delivering written notice to the other party.
In such event, if the parties’ respective representatives are unable to reach agreement on the
subject dispute within 10 business days after delivery of such notice, then each party shall,
within 5 business days thereafter, designate a senior executive officer of its management to meet
at a mutually agreed location to resolve the dispute.

(b) Arbitration. Subject to the dollar limitation set forth below, disputes as to any
work required to be performed by Landlord hereunder that are not resolved within 5 days by
agreement between the designated executive officers, may be submitted to arbitration if either
party so elects, by delivering written notice to the other party within 10 days after the
expiration of such 5 day period. In such event, the subject dispute shall be resolved by
arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration
Association, subject to the requirement that a single arbitrator unaffiliated with either party
shall decide each matter in dispute within 15 days of the date of his selection, based solely upon
the written statements of position submitted by each party and subject to the right of Landlord to
join in any such arbitration the Architect of Record (as defined herein) and any contractor whose
work is the subject of any such arbitration. The parties consent to the jurisdiction of any
appropriate court to enforce these arbitration provisions and to enter judgments upon the decision
of the arbitration. Unless otherwise required by state law, arbitration shall be conducted in the
City of Moreno Valley, California, or the American Arbitration Association office closest to such
city if there is no such office in such city. In the event of an arbitration, the losing party
shall pay the cost of arbitrator and the arbitration, but each party shall bear its own attorneys’
fees and costs in preparing for and participating in such arbitration. In any arbitration between
Landlord and contractor, either Landlord or Tenant shall be entitled to require that Tenant
participate and be bound as a party-in-interest.

4. Tenant’s Installations. Subject to applicable ordinances and building codes
governing Tenant’s right to occupy or perform in the Premises, and to the provisions of the Lease
regarding Tenant-Made Alterations, which apply to the Tenant’s initial installations before
Substantial Completion as well as any after Substantial Completion, Tenant shall be allowed to
install its improvements, machinery, equipment, fixtures, or other personal property on the
Premises when, in Landlord’s opinion, such installation will not interfere with Landlord’s
completion of construction or increase the cost thereof. Tenant does hereby agree to assume all
risk of loss or damage to its machinery, equipment, fixtures, and other personal property,
including any loss or damage resulting from the negligence of Landlord and to indemnify, defend,
and hold Landlord harmless from any and all liability, loss, or damage arising from any injury to
the property of Landlord, its contractors, subcontractors, or materialmen, and any death or
personal injury to any person or persons arising out of such occupancy or installation. All of
Tenant’s installation work shall be coordinated with Landlord’s general contractor. Prior to
commencement of any such installation work by Tenant, Landlord shall be furnished with evidence
that Tenant’s contractors have obtained and maintain adequate insurance to protect the Landlord and
its related parties from any liability resulting from such installation work. Landlord shall
receive a certificate of insurance evidencing such insurance coverage, which shall indicate that
Landlord is an additional insured. To the extent Tenant uses any of Landlord’s contractors or
subcontractors in connection with the installation of its improvements, Tenant acknowledges and
agrees that Landlord’s work shall take priority over that of the Tenant and that Tenant shall not
divert Landlord’s contractors or subcontractors from the performance of their work obligations for
Landlord.

5. Substantial Completion.

(a) Determination of Substantial Completion. Landlord shall diligently proceed with
the construction of the Landlord Improvements to achieve Substantial Completion, provided that such
commencement of construction shall not be more than 120 days following receipt of all entitlement
approvals and all required building permits from the applicable governmental authorities.
"Substantial Completion” shall be deemed to have occurred on the date upon which the
architect who prepared the Final Plans (“Architect of Record”) certifies that the Landlord
Improvements have been completed in substantial accordance with the Final Plans subject only to
completion of punch list items which do not materially interfere with the utilization of the
Landlord Improvements for the purposes for which they were intended.

(b) Inspection and Punch List. As soon as Substantial Completion has been achieved,
Landlord shall notify Tenant in writing of the date certified by the Architect of Record as the
date of Substantial Completion. Landlord shall notify Tenant in writing approximately 60 days
before the estimated date of Substantial Completion. Within 15 business days following the date of
Substantial Completion, Landlord and Tenant shall jointly inspect the Landlord Improvements and
agree upon a punch list of items in accordance with the Final Plans needing completion or
correction. Landlord shall use all reasonable diligent efforts to complete all punch list items
within 45 days after agreement upon the punch list, subject, however, to long lead time items which
must be ordered and to seasonal requirements for any landscaping and exterior work.

(c) Acceptance. Within 10 days after the Commencement Date, Tenant shall, upon
demand, execute and deliver to Landlord a letter of acceptance of delivery of the Premises and
confirmation of the Commencement Date. If Tenant occupies any portion of the Premises prior to
Substantial Completion, the terms of this Lease shall apply to such occupancy or use of the
Premises by Tenant. Except for incomplete punch list items referred to above, Tenant upon the
Commencement Date shall have and hold the Premises as the same shall then be without any liability
or obligation on the part of Landlord under this Lease for making any further alterations
improvements of any kind in or about the Premises during the Lease Term, or any extension or
renewal thereof.

(d) Tenant-Caused Delay. If Substantial Completion is delayed as a result of Tenant
Change Orders, Tenant’s interference with the construction of the Landlord Improvements, delays
resulting from Tenant’s using Landlord’s contractors and/or subcontractors to complete Tenant’s
installations), or Tenant’s failure to promptly respond to Landlord’s request to specify details or
layouts or other matters, then the Commencement Date shall be deemed to have occurred when, in the
opinion of the Architect of Record, Substantial Completion would have otherwise occurred and any
additional costs incurred by Landlord in completing the Landlord Improvements which are a result of
such Tenant-caused delays shall be reimbursed by Tenant upon demand by Landlord.

6. Tenant Improvements.

(a) In addition to the construction of the Landlord Improvements as described above, Landlord
agrees to construct those tenant improvements (the “Tenant Improvements”) specified below:

Dock equipment other than dock bumpers and “Z guards” at each door,
signage, gas system, MFL upgrades, including but not limited to, water
storage backup tank, metal deck roof structure, smoke detection and
automatic shut down, a second municipal water connection, separate fire
loop for on site hydrants, fire alarm system or fire extinguishers in
warehouse area, guard house, security system, electrical distribution, fire
alarm system, mezzanine deck, office and warehouse improvements.

(b) Landlord shall pay for the Tenant Improvements up to a maximum amount of $5,436,321, and
Tenant shall pay for the cost of the Tenant Improvements in excess of such amount. If the cost of
the Tenant Improvements is reasonably estimated by Landlord to exceed such amount, such estimated
overage shall be paid by Tenant before Landlord begins construction, and a final adjusting payment,
based upon the actual costs of the Tenant Improvements, shall be made promptly after Tenant accepts
possession of the Premises.

Landlord will competitively bid all Tenant Improvements and will disclose such bids to Tenant
on an “open book” basis.

If after approval of the Drawings (as defined below), Tenant shall desire any changes to the
Tenant Improvements it shall follow the procedure for Change Orders described in Paragraph 1(b)
above. Any and all costs of reviewing any Change Order Request relative to the Tenant
Improvements, and any and all costs of making any changes to the Tenant Improvements which Tenant
may request and which Landlord shall approve shall be at Tenant’s sole cost and expense, and shall
be paid to Landlord upon demand and before commencement of the work covered by the Change Order.

Landlord shall proceed with and complete the construction of the Tenant Improvements in a good
and workmanlike manner in accordance with all legal requirements and any Drawings prepared and
approved by the parties as described below. The construction of the Tenant Improvements shall, to
the extent possible, be coordinated with the construction of the Landlord Improvements. The
Landlord Improvements shall not be deemed to have achieved Substantial Completion until the Tenant
Improvements shall also have been Substantially Completed (also to be based upon the opinion of the
Architect of Record).

The Landlord and Tenant shall work together to prepare designs and construction drawings
(collectively, the “Drawings”) for the Initial Improvements and any such Drawings must be mutually
approved by Landlord and Tenant before work is commenced. The cost of such designs and drawings
shall be part of the allowance described above.

Tenant shall have the right to extend the Lease Term for an additional term of 4 years (such
additional term is hereinafter called the “First Extension Term”) commencing on the day
following the expiration of the Lease Term (hereinafter referred to as the “Commencement Date
of the First Extension Term”). Tenant shall give Landlord notice (hereinafter called the
"First Extension Notice”) of its election to extend the term of the Lease Term at least 12
months, but not more than 15 months, prior to the scheduled expiration date of the Lease Term.

provided Tenant has exercised its option for the First Extension Term; then Tenant shall have the
right to extend the Lease Term for an additional term of 5 years (such additional term is
hereinafter called the “Second Extension Term”) commencing on the day following the
expiration of the First Extension Term (hereinafter referred to as the “Commencement Date of
the Second Extension Term”). Tenant shall give Landlord notice (hereinafter called the
"Second Extension Notice”) of its election to extend the term of the Lease Term at least 12
months, but not more than 15 months, prior to the scheduled expiration date of the First Extension
Term.

(c) Provided that as of the time of the giving of the Third Extension Notice (as

(y) Tenant (or a Tenant Affiliate or a permitted assignee) actually occupies at least 50% of the
Premises initially demised under this Lease and any space added to the Premises, and (z) no Event

hereinafter called the “Third Extension Term”) commencing on the day following the
expiration of the Second Extension Term (hereinafter referred to as the “Commencement Date of
the Third Extension Term”). Tenant shall give Landlord notice (hereinafter called the
"Third Extension Notice”) of its election to extend the term of the Lease Term at least 12
months, but not more than 15 months, prior to the scheduled expiration date of the Second Extension
Term.

(d) The Base Rent payable by Tenant to Landlord during the First Extension Term shall be the
greater of:

(i) the Base Rent in effect on the expiration of the Lease Term, and

(ii) 95% of the Fair Market Rent, as defined and determined pursuant to Paragraphs (g),
(h), and (i) below.

(e) The Base Rent payable by Tenant to Landlord during the Second Extension Term shall be the
greater of:

(i) the Base Rent in effect on the expiration of the First Extension Term, and

(ii) 100% of the Fair Market Rent, as defined and determined pursuant to Paragraphs
(g), (h), and (i) below.

(f) The Base Rent payable by Tenant to Landlord during the Third Extension Term shall be the
greater of:

(i) the Base Rent in effect on the expiration of the Second Extension Term, and

(ii) 100% of the Fair Market Rent, as defined and determined pursuant to Paragraphs
(g), (h), and (i) below.

(g) The term “Fair Market Rent” shall mean the Base Rent, expressed as an annual rent
per square foot of floor area, which Landlord would have received from leasing the Premises for the
First Extension Term, the Second Extension Term, or the Third Extension Term, as applicable, to an
unaffiliated person which is not then a tenant in the Project, assuming that such space were to be
delivered in “as-is” condition, and taking into account the rental which such other tenant would
most likely have paid for such premises, provided that Fair Market Rent shall not in any event be
less than the Base Rent for the Premises as of the expiration of the Lease Term, the First
Extension Term, or Second Extension Term, as applicable. Fair Market Rent shall not be further
reduced by reason of any costs or expenses saved by Landlord by reason of Landlord’s not having to
find a new tenant for the Premises (including without limitation brokerage commissions, cost of
improvements necessary to prepare the space for such tenant’s occupancy, rent concession, or lost
rental income during any vacancy period). Fair Market Rent means only the rent component defined
as Base Rent in the Lease and does not include reimbursements and payments by Tenant to Landlord
with respect to Operating Expenses and other items payable or reimbursable by Tenant under the
Lease. In addition to its obligation to pay Base Rent (as determined herein), Tenant shall
continue to pay and reimburse Landlord as set forth in the Lease with respect to Operating Expenses
and other items with respect to the Premises during the First Extension Term, the Second Extension
Term, or the Third Extension Term, as applicable. The arbitration process described below shall be
limited to the determination of the Base Rent and shall not affect or otherwise reduce or modify
the Tenant’s obligation to pay or reimburse Landlord for such Operating Expenses and other
reimbursable items.

(h) Landlord shall notify Tenant of its determination of the Fair Market Rent (which shall be
made in Landlord’s sole discretion and shall in any event be not less than the Base Rent in effect
as of the expiration of the Lease Term or the First Extension Term or the Second Extension Term, as
applicable) for the First Extension Term, the Second Extension Term, or Third Extension Term, as
applicable, and Tenant shall advise Landlord of any objection within 10 days of receipt of
Landlord’s notice. Failure to respond within the 10-day period shall constitute Tenant’s
acceptance of such Fair Market Rent. If Tenant objects, Landlord and Tenant shall commence
negotiations to attempt to agree upon the Fair Market Rent within 30 days of Landlord’s receipt of
Tenant’s notice. If the parties cannot agree, each acting in good faith but without any obligation
to agree, then the Lease Term shall not be extended and shall terminate on its scheduled
termination date and Tenant shall have no further right hereunder or any remedy by reason of the
parties’ failure to agree unless Tenant or Landlord invokes the arbitration procedure provided
below to determine the Fair Market Rent.

(i) Arbitration to determine the Fair Market Rent shall be in accordance with the Real Estate
Valuation Arbitration Rules of the American Arbitration Association. Unless otherwise required by
state law, arbitration shall be conducted in the metropolitan area closest to the metropolitan area
where the Project is located by a single arbitrator unaffiliated with either party. Either party
may elect to arbitrate by sending written notice to the other party and the Regional Office of the
American Arbitration Association within 5 days after the 30-day negotiating period provided in
Paragraph (f), invoking the binding arbitration provisions of this paragraph. Landlord and Tenant
shall each submit to the arbitrator their respective proposal of Fair Market Rent. The arbitrator
must choose between the Landlord’s proposal and the Tenant’s proposal and may not compromise
between the two or select some other amount. Notwithstanding any other provision herein, the Fair
Market Rent determined by the arbitrator shall not be less than, and the arbitrator shall have no
authority to determine a Fair Market Rent less than, the Base Rent in effect as of the scheduled
expiration of the Lease Term, the First Extension Term, or the Second Extension Term, as
applicable. The decision of the arbitrator shall be final, binding and non-appealable. The cost
of the arbitration shall be paid by Landlord if the Fair Market Rent is that proposed by Landlord,
and by Tenant if the Fair Market Rent is that proposed by Tenant; and shall be borne equally
otherwise. If the arbitrator has not determined the Fair Market Rent as of the end of the Lease
Term, the First Extension Term, or the Second Extension Term, as applicable, Tenant shall pay 105
percent of the Base Rent in effect under the Lease as of the end of the Lease Term, the First
Extension Term, or the Second Extension Term, as applicable, until the Fair Market Rent is
determined as provided herein. Upon such determination, Landlord and Tenant shall make the
appropriate adjustments to the payments between them.

(j) The parties consent to the jurisdiction of any appropriate court to enforce the
arbitration provisions of this Addendum and to enter judgment upon the decision of the arbitrator.

(k) Except for the Base Rent as determined above, Tenant’s occupancy of the Premises during
the First Extension Term, the Second Extension Term, or the Third Extension Term, as applicable,
shall be on the same terms and conditions as are in effect immediately prior to the expiration of
the initial Lease Term, the First Extension Term, or the Second Extension Term, as applicable;
provided, however, Tenant shall have no further right to extend the Lease Term pursuant to this
addendum or to any allowances, credits or abatements or options to expand, contract, renew or
extend the Lease.

(l) If Tenant does not send the First Extension Notice, the Second Extension Notice, or the
Third Extension Notice, as applicable, within the period set forth in Paragraphs (a), (b) and (c),
Tenant’s right to extend the Lease Term shall automatically terminate. Time is of the essence as
to the giving of the First Extension Notice, the Second Extension Notice, or the Third Extension
Notice, as applicable, and the notice of Tenant’s objection under Paragraph (h).

(m) Landlord shall have no obligation to refurbish or otherwise improve the Premises for the
First Extension Term, the Second Extension Term, or the Third Extension Term, as applicable, but in
no event shall Landlord be relieved of its continuing repair, maintenance and other obligations
under the Lease. Subject to the foregoing, the Premises shall be tendered on the Commencement Date
of the First Extension Term, the Second Extension Term, or the Third Extension Term, as
applicable, in “as-is” condition.

(n) If the Lease is extended for the First Extension Term, the Second Extension Term, or the
Third Extension Term, as applicable, then Landlord shall prepare and Tenant shall execute an
amendment to the Lease confirming the extension of the Lease Term and the other provisions
applicable thereto.

(o) If Tenant exercises its right to extend the term of the Lease for the First Extension
Term, the Second Extension Term, or the Third Extension Term, as applicable, pursuant to this
Addendum, the term “Lease Term” as used in the Lease, shall be construed to include, when
practicable, the First Extension Term, the Second Extension Term, or the Third Extension Term,
except as provided in subparagraph (k) above.

ADDENDUM 4

MISCELLANEOUS PROVISIONS

1. Measurement of Premises. After completion of construction of the Building and
Improvements, and prior to the Commencement Date, Landlord shall cause its architect to measure the
rentable space in the Building and deliver to Tenant a written certificate certifying the correct
dimension of the Building. The measurement shall be made in accordance with current BOMA standards
for measurement of industrial buildings. Upon the determination of the actual floor area of the
Building, the base rent payable by Tenant hereunder shall be adjusted to reflect the floor area of
the Building.

2. Tax Proration. Landlord shall, at its expense, use its best efforts to have the
Premises separately assessed from any contiguous land which it owns. If the Premises are assessed
as part of a larger tax parcel (a “Tax Parcel”), Tenant shall pay to Landlord a proportionate
amount of all Taxes attributable to such Tax Parcel and the Building and Improvements thereon in
the manner hereinafter provided. When Tenant is required to pay a proportionate share of Taxes to
Landlord, the same shall be paid to Landlord within twenty (20) days following receipt of
Landlord’s written notification that such taxes and assessments are due. Landlord’s written
notification shall be forwarded to Tenant not later than thirty (30) days prior to the date such
taxes and assessments shall be due and shall be accompanied by a copy of the tax bill or
certificate and such additional information as Tenant may reasonably require to show how Tenant’s
proportionate share of such taxes and assessments was calculated, Tenant’s proportionate share of
such taxes and assessments shall be determined by Landlord on an equitable basis, considering the
respective land areas of the separate parcels which make up the Tax Parcel and the respective
leasable areas of any buildings constructed thereon.

3. Expansion Site. Landlord presently owns additional real property which is adjacent
to the Premises (on the westerly portion thereof, being on the NEC of Redlands Boulevard and
Eucalyptus Avenue), and which is reflected in Exhibit A as the “Expansion Site.” Landlord
represents that the Expansion Site will, after subdivision, be of sufficient size to accommodate a
500,000 square foot building. Landlord agrees that it will not construct any buildings or other
similar improvements (excluding landscaping, parking areas or facilities for utility installations)
on, or grant an interest to any third party not affiliated with Landlord in the Expansion Site for
a period of 3 years after the date of this Lease, and during such time period, if Tenant gives
notice of its desire to expand the Premises, the parties will negotiate the terms and conditions of
such expansion in good faith. In addition, at the end of such 3 year period, in consideration of
the payment of $1,000,000 by Tenant to Landlord within ten (10) days after such date, Tenant may
extend the 3 year period described above for another 1 year. If the parties reach an agreement and
execute an amendment to this Lease or a new lease covering such Expansion Space, the $1,000,000
payment will be applied against the first payments of Base Rent due Landlord thereunder. If the
Tenant declines to enter into an amendment to this Lease or a new lease for such Expansion Space
within sixty (60) days after Tenant has given Landlord notice of its election to proceed with the
expansion of the Premises, despite being offered commercially reasonable terms by Landlord, then no
part of such $1,000,000 payment shall be repayable to Tenant and shall be considered to be payment
for the option.

Upon the creation of the Premises as a separate legal parcel (by subdivision, parcel map or
lot line adjustment) and after Landlord has obtained all necessary land use entitlements required
to construct the Building and Improvements on the Premises, Landlord and Tenant shall execute a
Memorandum of Option (Lease) in the form of Exhibit “C” attached hereto, and Landlord shall record
such Memorandum (against the real property described therein) in the official records of Riverside
County, California. Upon expiration of the Tenant’s right to expand pursuant to this Paragraph,
Tenant will, promptly upon request of Landlord, execute and deliver to Landlord a quitclaim deed or
other instrument reasonably required by Landlord to eliminate the effect of the Memorandum from the
public records, which instrument shall be recorded by Landlord. The county recording fees and
title company charges, if any, for recording the Memorandum of Option (Lease) and the quitclaim or
other instrument reasonably required by Landlord to eliminate the effect of the Memorandum from the
public records, shall be paid by Tenant.

4. Net Lease. It is the intention of the parties hereto that the obligations of
Tenant hereunder shall be separate and independent covenants and agreements, and that Base Rent,
reimbursement of Operating Expenses and all other sums payable by Tenant hereunder shall continue
to be payable in all events, and that the obligations of Tenant hereunder shall continue
unaffected, unless the requirement to pay or perform the same shall have been terminated pursuant
to an express provision of this Lease. This is a net lease and Base Rent, reimbursement of
Operating Expenses and all other sums payable hereunder by Tenant shall be paid without notice or
demand, and without setoff, counterclaim, recoupment, abatement, suspension, deferment, diminution,
deduction, reduction or defense, except as otherwise specifically set forth herein. This Lease
shall not terminate and shall not have any right to terminate this Lease, during the Lease Term,
except as otherwise expressly provided herein. Tenant agrees that, except as otherwise expressly
provided herein, it shall not take any action to terminate, rescind or avoid this Lease for any
reason, including (i) the bankruptcy, insolvency, reorganization, composition, readjustment,
liquidation, dissolution, winding-up or other proceeding affecting Landlord (ii) under any mortgage
or deed of trust which may now or hereafter encumber the Premises (iii) any action with respect to
this Lease (including the rejection hereof) which may be taken by Landlord under the Federal
Bankruptcy Code or by any trustee, receiver or liquidator of Landlord or by any court under the
Federal Bankruptcy Code or otherwise, (iv) the Taking of the Premises or any portion thereof, (v)
the prohibition of restriction of Tenant’s use of the Premises or any portion thereof, (vii) the
eviction of Tenant from possession of the Premises, by paramount title or otherwise, or (viii)
default by Landlord hereunder on any other agreement between Landlord and Tenant. Tenant waives
all rights which are not expressly stated herein but which may now or hereafter otherwise be
conferred by law to quit, terminate or surrender this Lease or the Premises; to any setoff,
counterclaim, recoupment, abatement, suspension, deferment, diminution, deduction, reduction or
defense of or to Base Rent, reimbursement of Operating Expenses or any other sums payable under
this Lease, and for any statutory lien or offset right against Landlord or its property, each
except as otherwise expressly provided herein.

5. Statements. Tenant shall submit to Landlord (a) one hundred twenty (120) days of
the end of each fiscal year of Tenant annual balance sheets, income and cash flow statements for
Tenant, certified by an independent public accountant and (ii) within 90 days of the end of each
fiscal year, gross sales figures at the Premises during such fiscal year, certified by the senior
financial officer of Tenant. Quarterly 10Qs as filed with the Securities and Exchange Commission
shall satisfy the requirements contained in subparagraph (i) herein. Copies of the 10Ks filed with
the Securities and Exchange Commission will satisfy the requirement contained in subparagraph (ii).
The obligations of Tenant shall continue whether or not this Lease shall have been assigned
(unless Tenant has been released from liability hereunder). To the extent that any information
provided by Tenant to Landlord pursuant to this Paragraph is not otherwise available to the general
public, Landlord shall keep such information confidential and shall only disclose such information
to Landlord or Landlord’s Lender if any, and their respective agents, partners, members, employees,
attorneys, accountants, brokers and potential purchasers and investors, unless otherwise required
by a court order.

6. Ground Lease. Landlord represents to Tenant and Tenant acknowledges that at the
time of execution of this Lease, fee simple title to the Premises is held by certain affiliates of
Landlord, that Landlord is the tenant of the Premises under certain ground leases (collectively,
the “Ground Leases”), from the fee simple title holders (collectively, the “Ground Lessors”), and
that pursuant to the Ground Leases, Landlord has the unrestricted and absolute right to enter into
this Lease without the consent or approval of the Ground Lessors. Landlord further represents that
prior to the date that Tenant is required to take occupancy of the Premises under this Lease, it
intends to have acquired fee simple title to the Premises from the Ground Lessors, but even if it
does not, this Lease will continue in full force and effect and there will be no adverse effect on
any of the rights or obligations of Tenant hereunder by virtue of the existence of the Ground
Leases. As long as the Ground Leases remain in effect, this Lease shall be a sublease and
subordinate to the Ground Leases. Upon request of Tenant, Landlord shall provide Tenant with a
reasonable and customary form of non-disturbance agreement from the Ground Lessors, which will
state that notwithstanding any termination of the Ground Leases, as long as Tenant is not in
default under this Lease, and provided that upon any termination of the Ground Leases Tenant agrees
to attorn to the Ground Lessors, Tenant’s occupancy and possession of the Premises will not be
disturbed, and this Lease will continue in effect as a direct lease between Tenant and the Ground
Lessors.

7. Indemnification re Prior Lease. Tenant presently is the tenant under a lease dated
April 10, 2001 (as amended by a First Amendment to Lease dated October 22, 2003, the “Prior Lease”)
between Tenant and ProLogis California I, LLC (“ProLogis”), for the premises located at 4100 East
Mission Boulevard, Ontario, California (the “Ontario Premises”). Tenant represents to Landlord
that the Prior Lease is in full force and effect and has not been amended or modified except for
the First Amendment described above, and that no default or Event of Default exists under the Prior
Lease. It is understood and agreed that at such time that Tenant accepts possession of the
Premises under this Lease (the “Date of Possession”), it will vacate the Ontario Premises.
Landlord may, but shall not be required, to seek the consent of ProLogis to have the Prior Lease
assigned to and assumed by Landlord, or to seek the consent of ProLogis to sublease the Ontario
Premises at any time after the Date of Possession, and if Landlord elects to do so, Tenant agrees
to present Landlord’s proposal to assign or sublet to ProLogis. Tenant agrees that, unless
Landlord gives its prior written consent to the contrary, from and after the date of execution of
this Lease:

	 	1.	 	Tenant will not amend or modify the Prior Lease, nor will
Tenant exercise any option to extend the term thereof, nor will Tenant agree to
terminate the Prior Lease.

	 	2.	 	Tenant will not exercise any rights or privileges under the
Prior Lease, including any rights to make alterations to the Ontario Premises,
which would materially, adversely affect Landlord’s rights under this Section
7.

	 	3.	 	Tenant will not assign the Lease or sublease the Ontario
Premises, or any part thereof.

	 	4.	 	Tenant will not take any actions (or omit to take any actions)
which would (after any applicable notice and/or cure period) be an Event of
Default under the Prior Lease. The foregoing provision is not intended to
relate to the payment of rent or other monetary sums to ProLogis after the Date
of Possession (which will be Landlord’s obligations as set forth below).

On or before the Date of Possession, Tenant will vacate the Ontario Premises (but will not
surrender possession to ProLogis) in the condition required under Section 21 of the Prior
Lease.

On the Date of Possession Landlord shall pay, to Tenant, in good funds, the amount of the
security deposit (the “Prior Security Deposit”) which Tenant has paid to ProLogis pursuant to the
Prior Lease plus any interest accrued thereon but not yet paid to Tenant pursuant to Section 5 of
the Prior Lease. If the Prior Security Deposit plus any accrued interest is returned to Tenant
pursuant to the Prior Lease, then within five (5) business days of its receipt of such amount,
Tenant shall pay such amount to Landlord.

Tenant agrees to cooperate with Landlord (at no or nominal expense to Tenant), in connection
with any efforts undertaken by Landlord to have the Prior Lease assigned, or the Ontario Premises
(or any part thereof) subleased, to any third party from and after the Date of Possession.

If after the Date of Possession, the Prior Lease is assigned or the Ontario Premises are
subleased (with the consent of Landlord) and as a result there is a “profit” to Tenant (after
payment of 50% of such “profit” to ProLogis pursuant to Section 17 of the Prior Lease),
then all such “profit” shall be paid over to Landlord.

Until such time as Tenant is unconditionally released from all further liability under the
Prior Lease (other than liability for any acts or omissions which occurred prior to the Date of
Possession (“Prior Acts”), or any acts or omissions which occur after the Date of Possession which
are in breach of Tenant’s agreements under this Section 7 (“Subsequent Defaults”)),
Landlord agrees to indemnify any hold Tenant (and its officers, directors, and shareholders, and
their respective heirs, successors and assigns) free and harmless from all liability for Monetary
Claims (as defined herein) which arise subsequent to the Date of Possession. “Monetary Claims”
means claims by ProLogis (or any successor landlord under the Prior Lease) for unpaid rent
(including Base Rent and Operating Expense Payments) and other monetary sums payable by Tenant
under the Prior Lease. For clarification, Monetary Claims shall not include any claims made
against Tenant resulting from Prior Acts or Subsequent Defaults.

In furtherance of the foregoing indemnification, from and after the Date of Possession,
Landlord shall make all payments of Base Rent and estimated Operating Expenses to ProLogis when
payable under the Prior Lease. Provided that Tenant provides Landlord with copies of invoices for
Operating Expense Payments (other than for estimated Operating Expenses, which are provided for in
the preceding sentence), or other sums due to ProLogis under the Prior Lease, promptly upon receipt
by Tenant, Landlord will pay such invoices timely (but Landlord shall not be required to pay any
such invoice earlier than five (5) business days after receipt of the invoice from Tenant).
Notwithstanding the foregoing, Landlord may, in good faith, contest any such invoice to the same
extent that Tenant has the right to contest same under the Prior Lease. If and to the extent that
Tenant is required to expend any monetary sums to fulfill its obligations under the Prior Lease
(for example, without limitation, providing required insurance coverage, paying for utilities, and
paying sums due under any service contracts, including, without limitation, penalties for canceling
any such service contracts), then Landlord will reimburse Tenant for the actual cost thereof within
five (5) business days after receipt of an invoice from Tenant. Notwithstanding the foregoing,
Landlord may, in good faith, contest any such invoice and shall have the right to make all
determinations which affect such expenses, such as the selection of insurance carriers and
determination to cancel service contracts. Notwithstanding anything else to the contrary in this
Section 7, it is the intent of the parties that any and all monetary obligations which become due
under the Prior Lease on or after the Date of Possession (other than for Prior Acts and Subsequent
Defaults), shall be obligations of Landlord and not of Tenant.

If the Prior Lease is terminated pursuant to Section 23(iv) thereof or as a result of the
default by Landlord in fulfilling its indemnification obligations hereunder, any monetary judgment
which may be obtained by ProLogis (or any successor landlord under the Prior Lease) against Tenant
shall be considered a Monetary Claim.

If ProLogis (or any successor landlord under the Prior Lease) institutes legal action against
Tenant for any matters under the Prior Lease (other than Prior Acts or Subsequent Defaults), then
Landlord shall provide (at its expense) defense counsel reasonably acceptable to Tenant, and
Landlord shall be entitled to control the litigation, including any settlement thereof.

Redemption Date are deposited with the paying agent on or before such Special Mandatory Redemption
Date, and any applicable conditions set forth in the Indenture are satisfied, on and after such

Securities of this series together with accrued and unpaid interest from the date of initial
issuance to but excluding the Special Mandatory Redemption Date.

The Securities of this series are subject to redemption prior to the Stated Maturity upon not
less than 30 days notice by mail, at any time, in whole or in part, at the election of the Company,
at a redemption price equal to the greater of (1) 100% of the principal amount of such Securities
to be redeemed or (2) the sum of the present values of the remaining scheduled payments of
principal and interest on the Securities to be redeemed (exclusive of interest accrued to the date
of redemption) discounted to the date of redemption on a semiannual basis (assuming a 360-day year

Independent Investment Banker as having a maturity comparable to the remaining team (“Remaining

accordance with customary financial practice, in pricing new issues of corporate debt securities of
comparable maturity to the remaining term of such Securities.

“Comparable Treasury Price” means, with respect to any redemption date, (1) the average of the

appoints to act as the Independent Investment Banker from time to time.

Dealer, the Company shall substitute therefor another Primary Treasury Dealer.

and any redemption date, the average, as determined by the Trustee, of the bid and asked prices for

to constant maturity under the caption “Treasury Constant Maturities,” for the maturity
corresponding to the Comparable Treasury Issue; provided that, if no maturity is within
three months before or after the Remaining Life of the Securities to be redeemed, yields for the
two published maturities most closely corresponding to the Comparable Treasury Issue shall be
determined and the Treasury Rate shall be interpolated or extrapolated from such yields on a
straight line basis, rounding to the nearest month; or (2) if such release (or any successor
release) is not published during the week preceding the calculation date or does not contain such
yields, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a
percentage of its principal amount) equal to the Comparable Treasury Price for such redemption
date. The Treasury Rate shall be calculated on the third Business Day preceding the redemption
date.

Notice of the redemption will be mailed to holders of Securities by first-class mail at least
30 and not more than 60 days prior to the date fixed for redemption. If fewer than all of the
Securities are to be redeemed, the Trustee will select, not more than 60 days prior to the
redemption date, the particular Securities or portions thereof for redemption from the outstanding
Securities not previously called by such method as the Trustee deems fair and appropriate.

the Securities of this series, the Holders of not less than 25% in principal amount of the
Securities of this series at the time Outstanding shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default as Trustee and offered the Trustee

principal amount of Securities of this series at the time Outstanding a direction inconsistent with

such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted
by the Holder of this Security for the enforcement of any payment of principal hereof or any
premium or interest hereon on or after the respective due dates expressed herein.

shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay
the principal of and any premium and interest on this Security at the times, place and rate, and in
the coin or currency, herein described.

aggregate principal amount of Securities of this series and of like tenor of a different authorized
