sole cost, any damage or injury to the Premises caused thereby, and if not so removed, then

covenants, conditions, restrictions, easements, mortgages or deeds of trust, rights of way of

Page 1

 

to and will not violate the terms of any such Restrictions.

4. TERM AND RENTAL:

     A. Base Monthly Rent: The term (“Lease Term”) shall be for [thirty six (36)] months,
commencing on October 1, 2006 (the “Commencement Date”) and ending on September 30, 2009,
(“Expiration Date”). Notwithstanding the Parties agreement that the Lease Term begins on the
Commencement Date, this Lease and all of the obligations of Landlord and Tenant shall be binding
and in full force and effect from and after the Effective Date. In addition to all other sums
payable by Tenant under this Lease, Tenant shall pay base monthly rent (“Base Monthly Rent”) for
the Premises according to the following schedule:

	 	 	 
	10/1/06 - 09/30/07:

	 	$63,069.00 per month
	10/01/07 - 09130/08:

	 	$64,961.00 per month
	10/01/08 - 09/30/09:

	 	$66,910.00 per month

Base Monthly Rent shall be due in advance on or before the first day of each calendar month during
the Lease Term. All sums payable by Tenant under this Lease shall be paid to Landlord in lawful
money of the United States of America, without offset or deduction and without prior notice or
demand, at the address specified in Section 1 of this Lease or at such place or places as may be
designated in writing by Landlord during the Lease Term. Base Monthly Rent for any period less
than a calendar month shall be a pro rata portion of the monthly installment. Concurrently with
Tenant’s execution of this Lease, Tenant shall pay to Landlord the sum of Sixty Three Thousand
Sixty Nine and No/100 Dollars ($63,069.00) as a deposit to be applied on the Commencement Date
against the Base Monthly Rent due for the first month of the Lease Term.

     B. Late Charges: Tenant hereby acknowledges that late payment by Tenant to Landlord of Base
Monthly Rent and other sums due hereunder will cause Landlord to incur costs not contemplated by
this Lease, the exact amount of which is extremely difficult to ascertain, Such costs include but
are not limited to: administrative, processing, accounting, and late charges which may be imposed
on Landlord by the terms of any contract, revolving credit, mortgage, or trust deed covering the
Premises, Accordingly, if any installment of Base Monthly Rent or other sum due from Tenant shall
not be received by Landlord or its designee within five (5) days after Tenant’s receipt of
Landlord’s written notice of such failure to pay rent (“Late Rent Notice”), Tenant shall pay to
Landlord a late charge equal to five (5%) percent of such overdue amount, which late charge shall
be due and payable on the same date that the overdue amount was due. If Landlord sent a Late Rent
Notice to Tenant three (3) times within the Lease Term, all late charges subsequent to the third
Late Rent noticed shall become due automatically after Tenant’s failure to pay such Base Monthly
Rent or other sum due from Tenant within five (5) days after the same is due without any obligation
of Landlord to provide any Late Rent Notice to Tenant. The parties agree that such late charge
represents a fair and reasonable estimate of the costs Landlord will incur by reason of late
payment by Tenant, excluding interest and attorney’s fees and costs. If any rent or other sum due
from Tenant remains delinquent for a period in excess of thirty (30) days then, in addition to such
late charge, Tenant shall pay to Landlord interest on any rent that is not paid when due at the
Agreed Interest Rate (as defined in Section 19.J. below) following the date such amount became due
until paid. Acceptance by Landlord of such late charge shall not constitute a waiver of Tenant’s
default with respect to such overdue amount nor prevent Landlord from exercising any of the other
rights and remedies granted hereunder. In the event that a late charge is payable hereunder,
whether or not collected, for three (3) consecutive installments of Base Monthly Rent, then the
Base Monthly Rent shall automatically become due and payable quarterly in advance, rather than
monthly, notwithstanding any provision of this Lease to the contrary.

     C. Security Deposit: Concurrently with Tenant’s execution of this Lease, Tenant shall provide
Landlord a letter of credit (“Letter of Credit”) in the amount of Sixty Three Thousand Sixty Nine
and No/100 Dollars ($63,069.00) and in a form reasonably acceptable to Landlord (the Letter of
Credit and all proceeds thereof being referred to as the “Security “Deposit”). If Tenant defaults
with respect to any provisions of the Lease, including but not limited to the provisions relating
to payment of (i) Base Monthly Rent or other charges in default; or (ii) any other amount which
Landlord may spend or become obligated to spend by reason of Tenant’s default, Landlord shall be
entitled to draw the full amount of the Letter of Credit at any time by certifying the occurrence
of such default to the issuer. Landlord may, but shall not be obligated to, and without waiving or
releasing Tenant from any obligation under this Lease, use, apply or retain the whole or any part
of the Security Deposit reasonably necessary for the payment of any amount which Landlord may spend
by reason of Tenant’s default or

Page 2

 

as necessary to compensate Landlord for any loss or damage which
Landlord may suffer by reason of Tenant’s default, including without limitation loss of future
rents due under this Lease upon termination of this Lease due to a default by Tenant and other
damages recoverable under California Civil Code Section 1951.2. Tenant shall keep the Letter of
Credit in effect during the entire Lease Term, as the same may be extended, plus a period of four
(4) weeks following the Expiration Date. At least thirty (30) days prior to expiration of any
Letter of Credit, the term thereof shall be renewed or extended for a period of at least one (1)
year. Tenant’s failure to so renew or extend the Letter of Credit shall be a material default of
this Lease by Tenant. In the event Landlord draws against the Letter of Credit, Tenant shall
replenish the existing Letter of Credit or cause a new Letter of Credit to be issued such that the
aggregate amount of Letter of Credit available to Landlord at all times during the Lease Term is
the amount of the Security Deposit originally required. If Tenant performs every provision of this
Lease to be performed by Tenant, the Letter of Credit shall be returned to Tenant within thirty
(30) days alter the Expiration Date and surrender of the Premises to Landlord, less any amount
deducted in accordance with this Section 4.C., together with Landlord’s written notice itemizing
the amounts and purposes for such deduction. Tenant hereby waives California Civil Code Section
1950.7, or any similar law now or hereafter in effect which may have the effect of limiting the
circumstances under which Landlord would be allowed to use or apply the Security Deposit or amount
that could be so used or applied, or imposing a deadline for the return of the Security Deposit.
In the event of termination of Landlord’s interest in this Lease, Landlord shall deliver the Letter
of Credit to Landlord’s successor in interest in the Premises and thereupon be relieved of further
responsibility with respect to the Letter of Credit. If Tenant shall default more than three (3)
times in any twelve (12) month period, irrespective of whether or not such default is cured, then
the Security Letter of Credit shall, within ten (10) days after demand by Landlord, be increased by
Tenant to an amount equal to three (3) times the Base Monthly Rent.

5. CONSTRUCTION:

          Except as otherwise specifically provided in this Lease, The parties acknowledge that Landlord
is not performing any construction pursuant to this Lease.

6. ACCEPTANCE OF POSSESSION AND COVENANTS TO SURRENDER:

     A. Delivery and Acceptance: On the Commencement Date, Landlord shall deliver and Tenant shall
accept possession of the Premises and enter into occupancy of the Premises on the Commencement
Date; provided, however, that Landlord shall be responsible to put the existing heating,
ventilating and air conditioning (“HVAC”) systems, plumbing, sprinklers, electrical (including
panels and outlets), structural elements, and Building foundation into good operating condition and
repair, and replace all broken, marred, stained or inconsistent acoustical ceiling tiles. By
accepting possession, Tenant acknowledges that it has had an opportunity to conduct, and has
conducted, such inspections of the Premises as it deems necessary to evaluate its condition.
Except as otherwise specifically provided herein, Tenant agrees to accept possession of the
Premises in its then existing condition, subject to all Restrictions and without representation or
warranty by Landlord.

     B. Condition Upon Surrender: Tenant further agrees on the Expiration Date or on the sooner
termination of this Lease, to surrender the Premises to Landlord in good condition and repair,
normal wear and tear excepted. In this regard, “normal wear and tear” shall be construed to mean
wear and tear caused to the Premises by the natural aging process which occurs in spite of prudent
application of the best standards for maintenance, repair replacement, and janitorial practices,
and does not include items of neglected or deferred maintenance. In any event, Tenant shall cause
the following to be done prior to the Expiration Date or sooner termination of this Lease: (i) all
interior walls shall be patched, cleaned, and otherwise made paint-ready, (ii) all tiled floors
shall be cleaned and waxed, (iii) all carpets shall be cleaned and shampooed, (iv) all broken,
marred, stained or nonconforming acoustical ceiling tiles shall be replaced, (v) all cabling placed
above the ceiling by Tenant or Tenant’s contractors shall be removed, (vi) all windows shall be
washed; (vii) the HVAC system shall be serviced by a reputable and licensed service firm and left
in “good operating condition and repair” as so certified by such firm, and (viii) the plumbing and
electrical systems and lighting shall be placed in good order and repair (including replacement of
any burned out, discolored or broken light bulbs, ballasts, or lenses. On or before the Expiration
Date or sooner termination of this Lease, Tenant shall remove all its personal property and trade
fixtures (including Tenant’s phone switch and security systems) from the Premises. All

Page 3

 

property
and fixtures not so removed shall be deemed as abandoned by Tenant. Tenant shall ascertain from
Landlord at least ninety (90) days before the Expiration Date whether Landlord desires to have any
Alterations (as defined in Section 7), with the exception of Initial Alterations as defined in
Section 7 below, removed and the Premises or any parts thereof restored to their condition as of
the Commencement Date, or to cause Tenant to surrender all Alterations in place to Landlord. If
Landlord shall so desire, Tenant shall, at Tenant’s sole cost and expense, remove such Alterations
as Landlord requires and shall repair and restore said Premises or such parts thereof before the
Expiration Date. Such repair and restoration shall include causing the Premises to be brought into
compliance with all applicable building codes and laws in effect at the time of the removal to the
extent such compliance is necessitated by the repair and restoration work. As an alternative to
Tenant performing the restoration work as set forth in this Section 6.B, Tenant may request in
writing, no later than one hundred twenty (120) days prior to the Lease Expiration Date, that
Landlord provide an estimate of Tenant’s total surrender cost, and Tenant shall have the option to
pay Landlord such estimated amount in lieu of actually completing its surrender and restoration
obligations under this paragraph, such payment to be made to Landlord within fifteen (15) days of
Tenant’s receipt of such estimate.

     C. Failure to Surrender: If the Premises are not surrendered at the Expiration Date or sooner
termination of this Lease in the condition required by this Section 6, Tenant shall be deemed in a
holdover tenancy pursuant to this Section 6.C. and Tenant shall indemnify, defend, and hold
Landlord harmless against loss or liability resulting from delay by Tenant in so surrendering the
Premises including, without limitation, any claims made by any succeeding tenant founded on such
delay and costs incurred by Landlord in returning the Premises to the required condition, plus
interest at the Agreed Interest Rate as defined in Section 19.J. below. If Tenant remains in
possession of the Premises after the Expiration Date or sooner termination of this Lease without
Landlord’s consent, Tenant’s continued possession shall be on the basis of a tenancy at sufferance
and Tenant shall pay as rent during the holdover period an amount equal to one hundred fifty
percent (150%) of the Base Monthly Rent due in the month preceding the earlier termination or
Expiration Date, as applicable, plus all other amounts payable by Tenant under this Lease. Any
holding over shall otherwise be on the terms and conditions herein specified, except those
provisions relating to the Lease Term and any options to extend or renew, which provisions shall be
of no further force and effect. This provision shall survive the termination or expiration of the
Lease.

7. ALTERATIONS AND ADDITIONS:

     A. Tenant’s Alterations: Tenant shall not make, or suffer to be made, any alteration or
addition to the Premises (“Alterations”), or any part thereof, without obtaining Landlord’s prior
written consent, which consent shall not be unreasonably withheld, conditioned or delayed, and
delivering to Landlord the proposed architectural and structural plans for all such Alterations at
least fifteen (15) days prior to the start of construction. If such Alterations affect the
structure of the Building, Tenant additionally agrees to reimburse Landlord its reasonable
out-of-pocket costs incurred in reviewing Tenant’s plans. After obtaining Landlord’s consent,
which consent shall state whether or not Landlord will require Tenant to remove such Alteration at
the expiration or earlier termination of this Lease, Tenant shall not proceed to make such
Alterations until Tenant has obtained all required governmental approvals and permits, and provides
Landlord reasonable security, in form reasonably approved by Landlord, to protect Landlord against
mechanics’ lien claims. Tenant agrees to provide Landlord (i) written notice of the anticipated
and actual start-date of the work, (ii) a complete set of half-size (15” X 21”) vellum as-built
drawings (provided, however, that Landlord shall not require Tenant to update any of Landlord’s
existing “as-built” drawings), and (iii) a certificate of occupancy for the work upon completion of
the Alterations. All Alterations shall be constructed by a licensed general contractor in
compliance with all applicable building codes and laws including, without limitation, the Americans
with Disabilities Act of 1990 as amended from time to time. Upon the Expiration Date, all
Alterations, except movable furniture and trade fixtures (including Tenant’s phone switch and
security systems), shall become a part of the realty and belong to Landlord but shall nevertheless
be subject to removal by Tenant as provided in Section 6 above. Alterations which are not deemed
as trade fixtures include heating, lighting, electrical systems, air conditioning, walls,
carpeting, or any other installation which has become an integral part of the Premises. All
Alterations shall be maintained, replaced or repaired by Tenant at its sole cost and expense.

The parties acknowledge that Tenant intends to make certain improvements to the Premises (“Initial
Alterations”) prior to initial occupancy of the

Page 4

 

 Premises, as shown on the attached Exhibit
“B”. Landlord hereby consents to such Initial Alterations and waives any right to have such
Initial Alterations removed at the expiration or sooner termination of this Lease, provided Tenant
first obtains all necessary governmental approvals and permits associated with construction, and
thereafter complies with all provisions of the items (i), (ii) and (iii) of this Section 7.A.

     B. Free from Liens: Tenant shall keep the Premises free from all liens arising out of work
performed, materials furnished, or obligations incurred by Tenant or claimed to have been performed
for Tenant. In the event Tenant fails to discharge any such lien within ten (10) days after
receiving notice of the filing, Landlord shall immediately be entitled to discharge the lien at
Tenant’s expense and all resulting costs incurred by Landlord, including attorney’s fees shall be
due immediately from Tenant as additional rent.

     C. Compliance with Governmental Regulations: The term “Laws” or “Governmental Regulations”
shall include all federal, state, county, city or governmental agency laws, statutes, ordinances,
standards, rules, requirements, or orders now in force or hereafter enacted, promulgated, or
issued. The term also includes government measures regulating or enforcing public access, traffic
mitigation, occupational, health, or safety standards for employers, employees, landlords, or
tenants. Tenant, at Tenant’s sole expense will comply with all such Governmental Regulations
applicable to the premises or the Tenant’s use of the Premises and shall make all repairs,
replacements, alterations, or improvements necessary to comply with said Governmental Regulations.
The judgment of any court of competent jurisdiction or the admission of Tenant in any action or
proceeding against Tenant (whether Landlord be a party thereto or not) that Tenant has violated any
such law, regulation or other requirement in its use of the Premises shall be conclusive of that
fact as between Landlord and Tenant.

     D. Rooftop Communications Equipment: Notwithstanding the provisions of Section 7.A above,
Tenant shall have the right, at its sole cost and expense, to install antennae, satellite dishes
and other communications systems and equipment (“Rooftop Communications Systems”) on the roof of
the Building at no additional rent cost to Tenant and at a location reasonably acceptable to Tenant
and consistent with the intended use of the equipment while at the same time reasonably minimizing
its visibility. All permits, application fees, and all costs associated with the Rooftop
Communications Systems shall be Tenant’s responsibility. Tenant, at its sole cost and expense,
shall have the exclusive right to install, maintain, and from time to time replace all or a portion
of the Rooftop Communications Systems on the roof of the Building, provided that prior to
commencing any installation or maintenance, Tenant shall (i) obtain Landlord’s prior approval
(which approval shall not be unreasonably withheld, conditioned or delayed) of the proposed size,
weight and location of such Rooftop Communications Systems and method for fastening such Rooftop
Communications Systems to the roof, (ii) such installation and/or replacement shall comply strictly
with all Laws and the conditions of any bond or warranty maintained by Landlord on the roof, and
(iii) obtain, at Tenant’s sole cost and expense, any necessary federal, state, and municipal
permits, licenses and approvals, and deliver copies thereof to Landlord. Tenant agrees that all
installation, construction and maintenance shall be performed in a neat, responsible, and
workmanlike manner, using generally acceptable construction standards, consistent with such
reasonable requirements as shall be imposed by Landlord. Tenant shall repair any damage to the
Building caused by Tenant’s installation, maintenance, replacement, use or removal of the Rooftop
Communications Systems. The Rooftop Communications Systems shall remain the property of Tenant,
and Tenant may remove the Rooftop Communications Systems at its cost at any time during the Term.
Tenant shall remove the Rooftop Communications Systems at Tenant’s cost and expense upon the
expiration or termination of this Lease and shall repair any damage to the Building caused by such
removal. Landlord makes no warranty or representation that the Building or any portions thereof
are suitable for the use of the Rooftop Communications Systems. Except to the extent caused by
Landlord’s gross negligence or willful misconduct, Tenant shall protect, defend, indemnify and hold
harmless Landlord and Landlord’s agents, employees, shareholders, directors, officers, trustees,
partners, affiliates, contractors, subtenants or invitees (“Landlord’s Agents”) from and against
claims, damages, liabilities, costs and expenses of every kind and nature, including attorneys’
fees, incurred by or asserted against Landlord arising out of Tenant’s installation, maintenance,
replacement, use or removal of the Rooftop Communications Systems.

8. MAINTENANCE OF PREMISES:

     A. Landlord’s Obligations: Landlord at its sole cost and expense, shall maintain in good
condition, order, and repair, and replace as and when necessary, the foundation, exterior load
bearing walls and roof structure of the Building Shell.

     B. Tenant’s Obligations: Tenant shall clean, maintain, repair and replace when necessary the
Premises and every part thereof through regular inspections and servicing, including but not
limited to: (i) all plumbing and sewage facilities, (ii) all heating ventilating and air
conditioning facilities and equipment, (iii) all fixtures, interior walls floors, carpets and
ceilings, (iv) all windows, door entrances, plate glass and glazing systems including caulking, and
skylights, (v) all electrical facilities and equipment, (vi) all automatic fire extinguisher
equipment, (vii) the parking lot and all underground utility facilities servicing the Premises,
(viii) all elevator equipment, (ix) the roof membrane system (subject to Section 8.D below); and
(x) all waterscape, landscaping and shrubbery. All wall surfaces and floor tile are to be
maintained in an as good a condition as when Tenant took possession free of holes, gouges, or
defacements. With respect to items (ii), (viii) and (ix) above, Tenant shall provide Landlord a
copy of a service contract between Tenant and a licensed service contractor providing for periodic
maintenance of all such systems or equipment in conformance with the manufacturer’s
recommendations. Tenant shall provide Landlord a copy of such preventive maintenance contracts and
paid invoices for the recommended work if requested by Landlord.

     C. Waiver of Liability: Failure by Landlord to perform any defined services, or any cessation
thereof, when such failure is caused by accident, breakage, repairs, strikes, lockout or other
labor disturbances or labor disputes of any character or by any other cause, similar or dissimilar,
shall not render Landlord liable to Tenant in any respect, including damages to either person or
property, nor be construed as an eviction of Tenant, nor cause an abatement of rent, nor relieve
Tenant from fulfillment of any covenant or agreement hereof. Should any equipment or machinery
utilized in supplying the services listed herein break down or for any cause cease to function
properly, upon receipt of written notice from Tenant of any deficiency or failure of any services,
Landlord shall use reasonable diligence to repair the same promptly, but Tenant shall have no right
to terminate this Lease and shall have no claim for rebate of rent or damages on account of any
interruptions in service occasioned thereby or resulting therefrom. Tenant waives the provisions
of California Civil Code Sections 1941 and 1942 concerning the Landlord’s obligation of
tenantability and Tenant’s right to make repairs and deduct the cost of such repairs from the rent.
Landlord shall not be liable for a loss of or injury to person or property, however occurring,
through or in connection with or incidental to furnishing, or its failure to furnish, any of the
foregoing unless such loss or injury is due to Landlord’s gross negligence or willful misconduct.

     D. Capital Improvements: If as a part of Tenant’s fulfillment of its maintenance obligations
under this Section 8, a capital improvement or replacement to the Premises (with the exception of
the roof membrane) is paid for by Tenant which costs in excess of Ten Thousand Dollars
($10,000.00), Landlord shall reimburse Tenant for the cost of the replacement less the sum of (i)
Ten Thousand Dollars ($10,000.00) plus (ii) that portion of the remaining cost equal to the product
of such total cost multiplied by a fraction, the numerator of which is the number of years
remaining in the Lease Term, the denominator of which is the useful life (in years) of the
replacement, as reasonably determined in accordance with generally accepted accounting principles.
If the capital improvement is made during the Lease Term, Tenant’s share shall initially be based
on the Lease Term and if Tenant thereafter exercises its renewal Option (as defined in Section
18.A. below), then upon the commencement of the Option Term (as defined in Section 18.A. below), an
adjustment shall be made so that during the Option Term Tenant shall reimburse Landlord an amount
determined by multiplying the cost of the capital improvement by a fraction, the numerator of which
is the sum of the Lease Term remaining at the time the capital expenditure was made and the Option
Term and the denominator of which is the useful life of the capital improvement.

If Landlord and Tenant reasonably agree that a new roof membrane is necessary, Landlord shall
reimburse Tenant for the cost of the new roof membrane less the cost equal to the product of such
total cost multiplied by a fraction, the numerator of which is the number of years remaining in the
Lease Term, the denominator of which is the useful life (in years) of the roof membrane, as
reasonably determined in accordance with generally accepted accounting principles. If the roof
membrane is installed during the Lease Term, Tenant’s share shall initially be based on the Lease
Term and if Tenant thereafter exercises its Option, then upon the commencement of the Option Term,
an adjustment

Page 6

 

 shall be made so that during the Option Term Tenant shall reimburse Landlord an
amount determined by multiplying the cost of the roof membrane by a fraction, the numerator of
which is the sum of the Lease Term remaining at the time the roof membrane was installed and the
Option Term and the denominator of which is the useful life of the roof membrane.

9. HAZARD INSURANCE:

     A. Tenant’s Use: Tenant shall not use or permit the Premises, or any part thereof, to be used
for any purpose other than that for which the Premises are hereby leased; and no use of the
Premises shall be made or permitted, nor acts done, which will cause an increase in premiums or a
cancellation of any insurance policy covering the Premises or any part thereof, nor shall Tenant
sell or permit to be sold, kept, or used in or about the Premises, any article prohibited by the
standard form of fire insurance policies. Tenant shall, at its sole cost, comply with all
requirements of any insurance company or organization necessary for the maintenance of reasonable
fire and public liability insurance covering the Premises and appurtenances.

     B. Landlord’s Insurance: Landlord agrees to purchase and keep in force All Risk and fire
insurance in an amount equal to the replacement cost of the Building (not including any Initial
Alterations or Alterations paid for by Tenant) as determined by Landlord’s insurance company’s
appraisers. At Landlord’s election, such fire and property damage insurance may be endorsed to
cover loss caused by such additional perils against which Landlord may elect to insure, including
earthquake, flood or terrorist acts, and shall contain reasonable deductibles. Additionally
Landlord may maintain a policy of (i) commercial general liability insurance insuring Landlord (and
such others designated by Landlord) against liability for personal injury, bodily injury, death and
damage to property occurring or resulting from an occurrence in, on or about the Premises in an
amount as Landlord determines is reasonably necessary for its protection, and (ii) rental loss
insurance covering a twelve (12) month period. Tenant agrees to pay Landlord as additional rent,
on demand, the full cost of said insurance as evidenced by insurance billings to Landlord, and in
the event of damage covered by said insurance, the amount of any deductible under such policy.
Payment shall be due to Landlord within ten (10) days after written invoice to Tenant. It is
understood and agreed that Tenant’s obligation under this Section 9 will be prorated to reflect the
Lease Commencement and Expiration Dates.

     C. Tenant’s Insurance: Tenant agrees, at its sole cost, to insure its personal property,
Initial Alterations, and Alterations against damage for their full replacement value (without
depreciation). Said insurance shall provide All Risk and fire coverage equal to the replacement
cost of said property. The property casualty insurance provided by Tenant as required by this
paragraph shall be carried in favor of Landlord and Tenant as their respective interests may appear
and shall provide that any loss to Initial Alterations shall be adjusted with and be payable to
both Landlord and Tenant. Tenant shall deliver a copy of the policy and renewal certificate to
Landlord. Tenant agrees, at its sole cost, and to obtain worker’s compensation and Commercial
General Liability insurance for occurrences within the Premises with a combined single limit of not
less than Five Million Dollars ($5,000,000.00). Tenant’s liability insurance shall be primary
insurance containing a cross-liability endorsement, and shall provide coverage on an “occurrence”
rather than on a “claims made” basis. All such insurance shall provide for severability of
interests, and shall provide that an act or omission of one of the named (additional) insureds
shall not reduce or avoid coverage to the other named (additional) insureds. Tenant shall name
Landlord and Landlord’s lender as an additional insureds and shall deliver a copy of the policies
and renewal certificates to Landlord. All insurance policies required under this Section 9 shall
provide for thirty (30) days’ prior written notice to Landlord of any cancellation, termination, or
reduction in coverage. Notwithstanding the above, Landlord retains the right to have Tenant
provide other forms of insurance which may he reasonably required to cover future risks.

     D. Waiver: Landlord and Tenant hereby waive all tort, contract or other rights each may have
against the other on account of any loss or damage sustained by Landlord or Tenant, as the case may
be, or to the Premises or its contents, which may arise from any risk covered by their respective
insurance policies (or which would have been covered had such insurance policies been maintained in
accordance with this Lease) as set forth above. The Parties shall each obtain from their
respective insurance companies a waiver of any right of subrogation which said insurance company
may have against Landlord or Tenant, as the case may be.

Page 7

 

10. TAXES: Tenant shall be liable for and shall pay as additional rental, prior to
delinquency, the following: (i) all taxes and assessments levied against Tenant’s personal
property and trade or business fixtures; (ii) all real estate taxes and assessment installments or
other impositions or charges which may be levied on the Premises or upon the occupancy of the
Premises, including any substitute or additional charges which may be imposed applicable to the
Lease Term; and (iii) real estate tax increases due to an increase in assessed value resulting from
a sale, transfer or other change of ownership of the Premises as it appears on the City and County
tax bills during the Lease Term. All real estate taxes shall be prorated to reflect the Lease
Commencement and Expiration Dates. If, at any time during the Lease Term a tax, excise on rents,
business license tax or any other tax, however described, is levied or assessed against Landlord as
a substitute or addition, in whole or in part, for taxes assessed or imposed on the Premises’ land
or buildings, Tenant shall pay and discharge its pro rata share of such tax or excise on rents or
other tax before it becomes delinquent; except that this provision is not intended to cover net
income taxes, inheritance, gift or estate tax imposed upon Landlord. In the event that a tax is
placed, levied, or assessed against Landlord and the taxing authority takes the position that
Tenant cannot pay and discharge its pro rata share of such tax on behalf of Landlord, then at
Landlord’s sole election, Landlord may increase the Base Monthly Rent by the exact amount of such
tax and Tenant shall pay such increase. If by virtue of any application or proceeding brought by
Landlord, there results a reduction in the assessed value of the Premises during the Lease Term,
Tenant agrees to pay Landlord a fee consistent with the fees charged by a third party appeal firm
for such services.

11. UTILITIES: Tenant shall pay directly to the providing utility all water, gas, electric,
telephone, and other utilities supplied to the Premises. Landlord shall not be liable for loss of
or injury to person or property, however occurring, with the exception of any loss or injury
resulting from Landlord’s own gross negligence or willful misconduct, through or in connection with
or incidental to furnishing or the utility company’s failure to furnish utilities to the Premises,
and in such event Tenant shall not be entitled to abatement or reduction of any portion of Base
Monthly Rent or any other amount payable under this Lease.

12. TOXIC WASTE AND ENVIRONMENTAL DAMAGE:

     A. Use of Hazardous Material: Without the prior written consent of Landlord, Tenant or
Tenant’s agents, employees, contractors, subtenants or invitees (“Tenant’s Agents”) shall not cause
or permit any Hazardous Material, as defined below, to be generated, brought onto, used, stored,
created, released or disposed of in or about the Premises, except that Tenant may use and store
small quantities of common household cleaners and office supplies on the Premises provided such use
and storage is in strict compliance with all Environmental Laws, as defined below. As used herein,
the term “Hazardous Material” shall mean any substance, material or waste (whether liquid, solid or
gaseous), which is a pollutant or contaminant, or which is hazardous, toxic, ignitable, reactive,
corrosive, dangerous, harmful or injurious, or which presents a risk to public health or the
environment, or which is or may become regulated by or under the authority of any Environmental
Laws, as defined below, including, without limitation, asbestos or asbestos containing materials,
petroleum products, pesticides, polychlorinated biphenyls, flammable explosives, radioactive
materials and urea formaldehyde. As used herein, the term “Environmental Laws” shall mean any
present or future federal, state or local law, whether common law, statute, rule, regulation or
ordinance, judgment, order, or other governmental restriction, guideline, listing or requirement,
relating to the environment or any Hazardous Material, including without limitation, the
Comprehensive Environmental Response, Compensation, and Liability Act of 1980, 42 U.S.C. §9601 et
seq., the Resource Conservation and Recovery Act of 1976, 42 U.S.C. §6901 et seq., and applicable
provisions of the California Health and Safety Code and the California Water Code, all as
heretofore or hereafter may be amended from time to time. In order to obtain consent, Tenant shall
deliver to Landlord its written proposal describing the Hazardous Material to be brought onto the
Premises, measures to be taken for storage and disposal thereof, and safety measures to be employed
to prevent pollution or contamination of the air, soil, surface and ground water. Landlord’s
approval may be withheld in its reasonable judgment. In the event Landlord consents to Tenant’s
use of Hazardous Materials on the Premises or such consent is not required, Tenant represents and
warrants that it shall comply with all Governmental Regulations applicable to Hazardous Material
including doing the following: (i) adhere to all reporting and inspection requirements imposed by
Federal, State, County or Municipal laws, ordinances or regulations and provide Landlord a copy of
any such reports or agency inspections; (ii) obtain and provide Landlord copies of all necessary
permits required for the use

Page 8

 

and handling of Hazardous Material on the Premises; enforce Hazardous
Material handling and disposal practices consistent with industry standards; surrender the Premises
free from any Hazardous Materials arising from Tenant’s generating, bringing, using, storing,
creating, releasing, or disposing of Hazardous Material; and (v) properly close the facility with
regard to Hazardous Material including the removal or decontamination of any process piping,
mechanical ducting, storage tanks, containers, or trenches which have come into contact with
Hazardous Material and obtaining a closure certificate from the local administering agency prior to
the Expiration Date.

     B. Tenant’s Indemnity Regarding Hazardous Material: Tenant shall, at its sole cost and
expense and with counsel reasonably acceptable to Landlord, indemnify, defend and hold harmless
Landlord, Landlord’s Agents, successors and assigns from, and against any and all claims,
liabilities, obligations, penalties, fines, actions, costs or expenses incurred or suffered by the
foregoing parties arising from generating, bringing, using, storing, creating, releasing or
disposing of Hazardous Material by Tenant or Tenant’s Agents in or about the Premises, or the
violation of any Governmental Regulation or Environmental Laws by Tenant or Tenant’s Agents. This
indemnification applies whether or not the concentrations of any such Hazardous Material exceed
applicable maximum contaminant or action levels or any governmental agency has issued a cleanup
order. Tenant’s indemnification, defense, and hold harmless obligations include, without
limitation, the following: (i) claims, liabilities, costs or expenses resulting from or based upon
administrative, judicial (civil or criminal) or other action, legal or equitable, brought by any
private or public person under present or future laws, including Environmental Laws; (ii) claims,
liabilities, costs or expenses pertaining to the assessment and identification, monitoring,
cleanup, containment, or removal of Hazardous Material from soils, riverbeds or aquifers including
the provision of an alternative public drinking water source; (iii) losses attributable to
diminution in the value of the Premises or the Building (iv) loss or restriction of use of rentable
space in the Building; and (v) all other liabilities, obligations, penalties, fines, claims,
actions (including remedial or enforcement actions of any kind and administrative or judicial
proceedings, orders or judgments), damages (including consequential and punitive damages), and
costs (including attorney, consultant, and expert fees and expenses) resulting from the release or
violation. This Section 12B shall survive the expiration or termination of this Lease.

     C. Notice of Release or Violation: If, during the Lease Term (including any extensions),
Tenant becomes aware of (i) any actual or threatened release of a Hazardous Material on, under or
about the Premises or (ii) any inquiry, investigation, proceeding, claim, notice or order by any
private or public person or entity regarding the presence of hazardous Material on, under or about
the Premises, including alleged violations of Environmental Laws by Tenant or Tenant’s Agents,
Tenant shall give Landlord written notice of the release or investigation within five (5) days
after learning of it and shall simultaneously and thereafter furnish Landlord with copies of any
claims, notices of violation, reports, or other writings received by Tenant concerning the release
or investigation. In the event of an actual release of Hazardous Materials, Tenant shall also give
Landlord immediate verbal notice of such release.

          In the event of any release on or into the Premises or into the soil or ground water under the
Premises or the Building of any Hazardous Materials used, treated, stored or disposed of by Tenant
or Tenant’s Agents, Tenant agrees to comply, at its sole cost, with all laws, regulations,
ordinances and orders of any federal, state or local agency relating to the monitoring or
remediation of such Hazardous Materials. In the event of any such release of Hazardous Materials
Tenant shall immediately give verbal and follow-up written notice of the release to Landlord, and
Tenant agrees to meet and confer with Landlord and its Lender to attempt to eliminate and mitigate
any financial exposure to such Lender and resultant exposure to Landlord under California Code of
Civil Procedure Section 736(b) as a result of such release, and promptly to take reasonable
monitoring, cleanup and remedial steps given, inter alia, the historical uses to which the Property
has and continues to be used, the risks to public health posed by the release, the then available
technology and the costs of remediation, cleanup and monitoring, consistent with acceptable
customary practices for the type and severity of such contamination and all applicable laws.
Nothing in the preceding sentence shall eliminate, modify or reduce the obligation of Tenant under
12.B. of this Lease to indemnify, defend and hold Landlord harmless from any claims liabilities,
costs or expenses incurred or suffered by Landlord. Tenant shall provide Landlord prompt written
notice of Tenant’s monitoring, cleanup and remedial steps.

Page 9

 

          In the absence of an order of any federal, state or local governmental or quasi-governmental
agency relating to the cleanup, remediation or other response action required by applicable law,
any dispute arising between Landlord and Tenant concerning Tenant’s obligation to Landlord under
this Section 12.C. concerning the level, method, and manner of cleanup, remediation or response
action required in connection with such a release of Hazardous Materials shall be resolved by
mediation and/or arbitration pursuant to this Lease.

     D. Remediation Obligations: In the event of any release on, under or about the Premises of
any Hazardous Material generated, brought onto, used, stored, created or disposed of by Tenant or
Tenant’s Agents, Tenant shall, at its sole cost, promptly take all necessary and appropriate
actions, in compliance with applicable Environmental Laws, to remove or remediate such Hazardous
Material, whether or not any governmental agency has issued a cleanup order, so as to return the
Premises to the condition that existed before the introduction of such Hazardous Material. Tenant
shall obtain Landlord’s written consent prior to implementing any proposed removal or remedial
action, provided, however, that Tenant shall be entitled to respond immediately to an emergency
without first obtaining Landlord’s written consent. Nothing in the preceding sentence shall in any
way eliminate, modify or reduce the obligation of Tenant under Section 12.B. above to indemnify,
defend and hold Landlord harmless from any claims, liabilities, costs or expenses incurred or
suffered by Landlord.

     E. Environmental Monitoring: Landlord and its agents shall have the right to inspect,
investigate, sample and monitor the Premises, including any air, soil, water, ground water, or to
conduct any other sampling or testing, digging, drilling or analysis, to determine whether Tenant
is complying with the terms of this Section 12. If Landlord discovers that Tenant is not in
compliance with the terms of this Section 12, any costs incurred by Landlord in determining
Tenant’s non-compliance, including attorneys’, consultants’ and experts’ fees, shall be due and
payable by Tenant to Landlord within five (5) days following Landlord’s written demand therefor.

     F. Landlord Indemnification: Landlord shall indemnify and hold Tenant harmless from any
claims, liabilities, costs or expenses (including, without limitation, all litigation costs, expert
witness fees and reasonable attorneys’ fees) incurred or suffered by Tenant related to the removal,
investigation, monitoring or remediation of Hazardous Materials which are present as of the
Effective Date or which come to be present on the Premises as a result of Landlord’s actions after
the Effective Date. Landlord’s indemnification and hold harmless obligations include, without
limitation, (i) claims, liability, costs or expenses resulting from or based upon administrative,
judicial (civil or criminal) or other action, legal or equitable, brought by any private or public
person under common law or under the Comprehensive Environmental Response, Compensation and
Liability Act of 1980 (“CERCLA”), the Resource Conservation and Recovery Act of 1980 (“RCRA”) or
any other Federal, State, County or Municipal law, ordinance or regulation, (ii) claims,
liabilities, costs or expenses pertaining to the identification, monitoring, cleanup, containment,
or removal of Hazardous Materials from soils, riverbeds or aquifers including the provision of an
alternative public drinking water source, and (iii) all costs of defending such claims. In no
event shall Landlord be liable for any consequential damages suffered or incurred by Tenant as a
result of any such contamination. To the best of Landlord’s knowledge, there are no Hazardous
Materials on or beneath the Premises, nor does Landlord have reasonable cause to believe Hazardous
Materials are present on or beneath the Premises.

Page 10

 

13. TENANT’S DEFAULT: The occurrence of any of the following shall constitute a material
default and breach of this Lease by Tenant: (i) Tenant’s failure to pay the Base Monthly Rent
including additional rent or any other payment due under this Lease where such failure continues
for five (5) business days after Tenants receipt of Landlord’s notice that Rent was not received,
(ii) the abandonment of the Premises by Tenant; (iii) Tenant’s failure to observe and perform any
other required provision of this Lease, where such failure continues for thirty (30) days after
written notice from Landlord; provided however, that if the nature of the default is such that it
cannot reasonably be cured within the 30-day period, Tenant shall not be deemed in default if it
commences within such period to cure, and thereafter diligently prosecutes the same to completion;
(iv) Tenant’s making of any general assignment for the benefit of creditors; (v) the filing by or
against Tenant of a petition to have Tenant adjudged a bankrupt or of a petition for reorganization
or arrangement under any law relating to bankruptcy (unless, in the case of a petition filed
against Tenant, the same is dismissed after the filing); (vi) the appointment of a trustee or
receiver to take possession of substantially all of Tenant’s assets located at the Premises or of
Tenant’s interest in this Lease, where possession is not restored to Tenant within thirty (30)
days; (vii) the attachment, execution or other judicial seizure of substantially all of Tenant’s
assets located at the Premises or of Tenant’s interest in this Lease, where such seizure is not
discharged within thirty (30) days; or (viii) the occurrence of any other event described as a
default elsewhere in this Lease or any amendment thereto regardless of whether such event is
defined as a material default and breach of this Lease in this Section 13.

     A. Remedies: In the event of any such default by Tenant, then in addition to other remedies
available to Landlord at law or in equity, Landlord shall have the immediate option to terminate
this Lease and all rights of Tenant hereunder by giving written notice of such intention to
terminate. In the event Landlord elects to so terminate this Lease, Landlord may recover from
Tenant all the following: (i) the worth at time of award of any unpaid rent which had been earned
at the time of such termination; (ii) the worth at time of award of the amount by which the unpaid
rent which would have been earned after termination until the time of award exceeds the amount of
such rental loss for the same period that Tenant proves could have been reasonably avoided; (iii)
the worth at time of award of the amount by which the unpaid rent for the balance of the Lease Term
after the time of award exceeds the amount of such rental loss that Tenant proves could be
reasonably avoided; (iv) any other amount necessary to compensate Landlord for all detriment
proximately caused by Tenant’s failure to perform its obligations under this Lease, or which in the
ordinary course of things would be likely to result therefrom; including: (a) expenses for
repairing, altering or remodeling the Premises for purposes of reletting, (b) broker’s fees,
advertising costs or other expenses of reletting the Premises, (c) costs of carrying the Premises
such as taxes, insurance premiums, utilities and security precautions; and (d) at Landlord’s
election, such other amounts in addition to or in lieu of the foregoing as may be permitted by
applicable California law. The term “rent”, as used herein, is defined as the minimum monthly
installments of Base Monthly Rent and all other sums required to be paid by Tenant pursuant to this
Lease, all such other sums being deemed as additional rent due hereunder. As used in (i) and (ii)
above, “worth at the time of award” shall be computed by allowing interest at a rate equal to the
discount rate of the Federal Reserve Bank of San Francisco plus five (5%) percent per annum. As
used in (iii) above, “worth at the time of award” shall be computed by discounting such amount at
the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one (1%)
percent.

     B. Right to Re-enter: In the event of any such default by Tenant, Landlord shall have the
right, after terminating this Lease, to re-enter the Premises and remove all persons and property.
Such property may be removed and stored in a public warehouse or elsewhere at the cost of and for
the account of Tenant, and disposed of by Landlord in any manner permitted by law.

     C. Continuation of Lease: If Landlord does not elect to terminate this Lease as provided in
Section 13.A or 13.B above, then the provisions of California Civil Code Section 1951.4, (Landlord
may continue to keep this Lease in effect after Tenant’s breach and abandonment and recover rent as
it becomes due if Tenant has a right to sublet and assign, subject only to reasonable limitations)
as amended from time to time, shall apply and Landlord may from time to time, without terminating
this Lease, either recover all rental as it becomes due or relet the Premises or any part thereof
for such term or terms and at such rental or rentals and upon such other terms and conditions as
Landlord in its sole discretion may deem advisable, with the right to make alterations and repairs
to the Premises. In the event that Landlord elects to so relet, rentals received

Page 11

 

by Landlord from
such reletting shall be applied in the following order to: (i) the payment of any indebtedness
other than Base Monthly Rent due hereunder from Tenant to Landlord; (ii) the payment of any cost of
such reletting; (iii) the payment of the cost of any alterations and repairs to the Premises; and
(iv) the payment of Base Monthly Rent and other sums due and unpaid hereunder. The residual
rentals, if any, shall be held by Landlord and applied in payment of future Base Monthly Rent as
the same may become due and payable hereunder. Landlord shall the obligation to market the space
but shall have no obligation to relet the Premises following a default if Landlord has other
comparable available space within the Building or Premises. In the event the portion of rentals
received from such reletting which is applied to the payment of rent hereunder during any month be
less than the rent payable during that month by Tenant hereunder, then Tenant shall pay such
deficiency to Landlord immediately upon demand. Such deficiency shall be calculated and paid
monthly. Tenant shall also pay to Landlord, as soon as ascertained, any costs and expenses
incurred by Landlord in such reletting or in making such alterations and repairs not covered by the
rentals received from such reletting.

     D. No Termination: Landlord’s re-entry or taking possession of the Premises pursuant to 13.B
or 13.C shall not be construed as an election to terminate this Lease unless written notice of such
intention is given to Tenant or unless the termination is decreed by a court of competent
jurisdiction. Notwithstanding any reletting without termination by Landlord because of any default
by Tenant, Landlord may at any time after such reletting elect to terminate this Lease for any such
default.

     E. Non-Waiver: Landlord may accept Tenant’s payments without waiving any rights under this
Lease, including rights under a previously served notice of default. No payment by Tenant or
receipt by Landlord of a lesser amount than any installment of rent due shall be deemed as other
than payment on account of the amount due. If Landlord accepts payments after serving a notice of
default, Landlord may nevertheless commence and pursue an action to enforce rights and remedies
under the previously served notice of default without giving Tenant any further notice or demand.
Furthermore, the Landlord’s acceptance of rent from the Tenant when the Tenant is holding over
without express written consent does not convert Tenant’s Tenancy from a tenancy at sufferance to a
month to month tenancy. No waiver of any provision of this Lease shall be implied by any failure
of Landlord to enforce any remedy for the violation of that provision, even if that violation
continues or is repeated. Any waiver by Landlord of any provision of this Lease must be in
writing. Such waiver shall affect only the provision specified and only for the time and in the
manner stated in the writing. No delay or omission in the exercise of any right or remedy by
Landlord shall impair such right or remedy or be construed as a waiver thereof by Landlord. No act
or conduct of Landlord, including, without limitation, the acceptance of keys to the Premises,
shall constitute acceptance of the surrender of the Premises by Tenant before the Expiration Date.
Only written notice from Landlord to Tenant of acceptance shall constitute such acceptance of
surrender of the Premises. Landlord’s consent to or approval of any act by Tenant which requires
Landlord’s consent or approvals shall not be deemed to waive or render unnecessary Landlord’s
consent to or approval of any subsequent act by Tenant.

     F. Performance by Landlord: If Tenant fails to perform any obligation required under this
Lease or by law or governmental regulation, Landlord in its sole discretion may, without notice,
without waiving any rights or remedies and without releasing Tenant from its obligations hereunder,
perform such obligation, in which event Tenant shall pay Landlord as additional rent all sums paid
by Landlord in connection with such substitute performance, including interest at the Agreed
Interest Rate (as defined in Section 19.J) within ten (10) days of Landlord’s written notice for
such payment.

     G. Habitual Default: The provisions of Section 13 notwithstanding, the Parties agree that if
Tenant shall have defaulted in the performance of any (but not necessarily the same) term or
condition of this Lease for three or more times during any twelve (12) month period during the
Lease Term (beyond applicable notice and cure periods), then such conduct shall, at the election of
the Landlord, represent a separate event of default which cannot be cured by Tenant. Tenant
acknowledges that the purpose of this provision is to prevent repetitive defaults by Tenant, which
work a hardship upon Landlord and deprive Landlord of Tenant’s timely performance under this Lease.

14. LANDLORD’S LIABILITY:

     A. Limitation on Landlord’s Liability: In the event of Landlord’s failure to perform any of
its covenants or agreements under this Lease, Tenant shall give Landlord written notice of such
failure and shall give Landlord thirty (30) days to cure or

Page 12

 

commence to cure such failure prior to
any claim for breach or resultant damages, provided, however, that if the nature of the default is
such that it cannot reasonably be cured within the 30-day period, Landlord shall not be deemed in
default if it commences within such period to cure, and thereafter diligently prosecutes the same
to completion. In addition, upon any such failure by Landlord, Tenant shall give notice by
registered or certified mail to any person or entity with a security interest in the Premises
(“Mortgagee”) that has provided Tenant with notice of its interest in the Premises, and shall
provide Mortgagee a reasonable opportunity to cure such failure, including such time to obtain
possession of the Premises by power of sale or judicial foreclosure, if such should prove necessary
to effectuate a cure. Tenant agrees that each of the Mortgagees to whom this Lease has been
assigned is an expressed third-party beneficiary hereof. Tenant waives any right under California
Civil Code Section 1950.7 or any other present or future law to the collection of any payment or
deposit from Mortgagee or any purchaser at a foreclosure sale of Mortgagee’s interest unless
Mortgagee or such purchaser shall have actually received and not refunded the applicable payment or
deposit. Tenant further waives any right to terminate this Lease and to vacate the Premises on
Landlord’s default under this Lease. Tenant’s sole remedy on Landlord’s default is an action for
damages or injunctive or declaratory relief; provided, however, Landlord and its partners,
trustees, beneficiaries and employees shall not be liable to Tenant for any consequential damages
suffered or incurred by Tenant on account of Landlord’s default including, without limitation, on
account of lost profits or the interruption of Tenant’s business. Tenant hereby agrees that
Landlord shall not be liable for injury to Tenant’s business or any loss of income therefrom or for
damage to the goods, wares, merchandise, or other property of Tenant, Tenant’s employees, invitees,
customers, or any other person in or about the Premises, nor shall Landlord be liable for injury to
the person of Tenant, Tenant’s employees, agents, or contractors, whether such damage or injury is
caused by or results from fire, steam, electricity, gas, water, or rain, or from the breakage,
leakage, obstruction, or other defects of pipes, sprinklers, wires, appliances, plumbing, air
conditioning, or lighting fixtures, or from any other cause, whether said damage or injury results
from conditions arising upon the Premises or from other sources or places and regardless of whether
the cause of such damage or injury or the means of repairing the same is inaccessible to Tenant,
with the exception of damage resulting from Landlord’s gross negligence or willful misconduct.

     B. Limitation on Tenant’s Recourse: If Landlord is a corporation, trust, partnership, joint
venture, unincorporated association or other form of business entity, then the obligations of
Landlord shall not constitute personal obligations of the officers, directors, trustees, partners,
joint venturers, members, owners, stockholders, or other principals or representatives except to
the extent of their property interest in the Premises. Tenant shall have recourse only to the
interest of Landlord in the Premises for the satisfaction of the obligations of Landlord and shall
not have recourse to any other assets of Landlord for the satisfaction of such obligations.

     C. Indemnification of Landlord: Except to the extent due to the negligence or willful
misconduct of Landlord, as a material part of the consideration rendered to Landlord, Tenant hereby
waives all claims against Landlord for damages to goods, wares and merchandise, and all other
personal property in, upon or about said Premises and for injuries to persons in or about said
Premises, from any cause arising at any time to the fullest extent permitted by law, and Tenant
shall indemnify, defend with counsel reasonably acceptable to Landlord and hold harmless Landlord
and Landlord’s Agents from any claims, liabilities, costs or expenses incurred or suffered arising
from the use or occupancy of the Premises by Tenant or Tenant’s Agents, the acts or omissions of
Tenant or Tenant’s Agents, tenant’s breach of this Lease, or any damage or injury to person or
property from any cause, including but not limited to the use or occupancy of the Premises by
Tenant or Tenant’s Agents, the acts or omissions of Tenant or Tenant’s Agents, Tenant’s breach of
this Lease or from the failure of Tenant to keep the Premises in good condition and repair as
herein provided. Further, in the event Landlord is made party to any litigation due to the acts or
omission of Tenant or Tenant’s Agents, Tenant will indemnify, defend (with counsel reasonably
acceptable to Landlord) and hold Landlord harmless from any such claim or liability including
Landlord’s costs and expenses and reasonable attorney’s fees incurred in defending such claims.

15. DESTRUCTION OF PREMISES:

     A. Landlord’s Obligation to Restore: In the event of a destruction of the Premises during the
Lease Term Landlord and Tenant, to the extent of its Initial Alterations and Alterations, shall
repair the same to a similar condition to that which existed prior to such destruction. Such
destruction shall not annul or void this Lease; however, Tenant shall be entitled to a
proportionate reduction of Base Monthly Rent

Page 13

 

while repairs are being made, such proportionate
reduction to be based upon the extent to which the repairs interfere with Tenant’s business in the
Premises, as reasonably determined by Landlord. In no event shall Landlord be required to replace
or restore Initial Alterations, Alterations, or Tenant’s fixtures or personal property. Tenant
shall be obligated to replace and restore all Initial Alterations and Alterations.

     B. Limitations on Landlord’s Restoration Obligation: Notwithstanding the provisions of
Section 15.A, Landlord shall have no obligation to repair, or restore the Promises if any of the
following occur: (i) if the repairs cannot be made in one hundred eighty (180) days from the date
of receipt of all governmental approvals necessary under the laws and regulations of State,
Federal, County or Municipal authorities, as reasonably determined by Landlord, (ii) if the holder
of the first deed of trust or mortgage encumbering the Building elects not to permit the insurance
proceeds payable upon damage or destruction to be used for such repair or restoration, (iii) the
damage or destruction is not fully covered by the insurance maintained by Landlord, (iv) the damage
or destruction occurs in the last twenty four (24) months of the Lease Term, (v) Tenant is in
default pursuant to the provisions of Section 13, or (vi) Tenant has vacated the Premises for more
than ninety (90) days. In any such event Landlord may elect either to (i) complete the repair or
restoration, or (ii) terminate this Lease by providing Tenant written notice of its election within
sixty (60) days following the damage or destruction if Landlord elects to repair or restore, this
Lease shall continue in full force and effect. Tenant shall also have the right to terminate this
Lease in the event of either (i) or (iv) above, by providing Landlord with written notice of its
election to do so as follows: in the case of clause (i) above, written notice fifteen (15) days
after Landlord’s notice of the time period required for repair or restoration; and in the case of
clause (ii) above, within thirty (30) days following the damage or destruction. Tenant hereby
waives the benefits and rights provided to Tenant by the provisions of Civil Code Sections 1932 and
1933.

16. CONDEMNATION: If any part of the Premises shall be taken for any public or quasi-public
use, under any statute or by right of eminent domain or private purchase in lieu thereof, and only
a part thereof remains which is susceptible of occupation hereunder, this Lease shall, as to the
part so taken, terminate as of the day before title vests in the condemnor or purchaser (“Vesting
Date”) and Base Monthly Rent payable hereunder shall be adjusted so that Tenant is required to pay
for the remainder of the Lease Term only such portion of Base Monthly Rent as the value of the part
remaining after such taking bears to the value of the entire Premises prior to such taking.
Further, in the event of such partial taking, Landlord shall have the option to terminate this
Lease as of the Vesting Date. If all of the Premises or such part thereof be taken so that there
does not remain a portion susceptible for occupation hereunder, this Lease shall terminate on the
Vesting Date. If part or all of the Premises be taken, all compensation awarded upon such taking
shall go to Landlord, and Tenant shall have no claim thereto; except Landlord shall cooperate with
Tenant, without cost to Landlord, to recover compensation for damage to or taking of any Initial
Alterations, Alterations, or for Tenant’s moving costs. Tenant hereby waives the provisions of
California Code of Civil Procedures Section 1265.130 and any other similarly enacted statue, and
the provisions of this Section 16 shall govern in the case of a taking.

17. ASSIGNMENT OR SUBLEASE:

     A. Consent by Landlord: Except as specifically provided in Section 17.E below, Tenant may not
voluntarily, involuntarily or by operation of law, assign, sell or otherwise transfer all or any
part of Tenant’s interest in this Lease or in the Premises, cause or permit any part of the
Premises to be sublet, occupied or used by anyone other than Tenant, or permit any person to
succeed to any interest in this Lease or the Premises (all of the foregoing being a “Transfer”)
without the express written consent of Landlord, which consent shall not be unreasonably withheld,
conditioned or delayed. In the event Tenant desires to effectuate a Transfer, Tenant shall deliver
to Landlord (i) executed counterparts of any agreement and of all ancillary agreements with the
proposed transferee, (ii) current financial statements of the transferee covering the preceding
three years if such statements exist and are otherwise available, (iii) the nature of the proposed
transferee’s business to be carried on in the Premises, (iv) a statement outlining all
consideration to be given on account of the Transfer, and (v) a current financial statement of
Tenant. Landlord may condition its approval of any Transfer on receipt of a certification from
both Tenant and the proposed transferee of all consideration to be paid to Tenant in connection
with such Transfer. At Landlord’s request, Tenant shall also provide additional information
reasonably required by Landlord to determine whether it will consent to the proposed Transfer.
Landlord shall have a fifteen (15) day period following receipt of all the foregoing within which
to notify Tenant in

Page 14

 

writing that Landlord elects to: (i) terminate this Lease as to the portion of
the Premises proposed to be transferred; (ii) permit Tenant to Transfer such space to the named
transferee on the terms and conditions set forth in the notice; or (iii) refuse consent, provided
Landlord shall be required to specify its reasons for refusing consent. If Landlord should fail to
notify Tenant in writing of such election within the aforementioned 15-day period, Landlord shall
be deemed to have elected option (ii) above. In the event Landlord elects option (i) above, this
Lease shall expire with respect to such part of the Premises on the date upon which the proposed
Transfer was to commence, and from such date forward, Base Monthly Rent and Tenant’s allocable
share of all other costs and charges shall be adjusted based upon the proportion that the rentable
area of the Premises remaining bears to the total rentable area of the Building. In the event
Landlord does not elect option (i) above, Landlord’s consent to the proposed Transfer shall not be
unreasonably withheld, conditioned or delayed, provided and upon the condition that: (i) the
proposed transferee is engaged in a business that is limited to the use expressly permitted under
this Lease; (ii) the proposed transferee is a company with sufficient financial worth and
management ability to undertake the financial obligation of this Lease and Landlord has been
furnished with reasonable proof thereof; (iii) the proposed transfer agreement, if it is a
sublease, conforms to the requirements of Section 17.I below (Sublease Requirements) or if it is an
assignment, is in a form reasonably satisfactory to Landlord; (iv) the proposed Transfer will not
result in there being greater than two (2) subtenants or other occupants (not including employees)
within the Premises at any time during the Lease Term; (v) Tenant reimburses Landlord on demand for
any costs that may be incurred by Landlord in connection with said Transfer, including the costs of
making investigations as to the acceptability of the proposed transferee and legal costs incurred
in connection with the granting or denial of any requested consent; provided, however, that such
reimbursement payment by Tenant to Landlord shall not exceed One Thousand Five Hundred and No/100
Dollars ($1,500.00) and (vi) Tenant shall not have advertised or publicized in any way the
availability of the Premises without prior notice to Landlord. In the event all or any one of the
foregoing conditions are not satisfied (without limiting other factors that may be considered or
conditions that may be imposed by Landlord in connection with a requested Transfer), Landlord shall
be considered to have acted reasonably if it withholds its consent. Tenant shall not hypothecate,
mortgage, pledge or otherwise encumber Tenant’s interest in this Lease or the Premises or otherwise
use the Lease as a security device in any manner (all of the foregoing being an “Hypothecation”)
without the consent of Landlord, which consent Landlord may withhold in its sole discretion.
Tenant shall reimburse Landlord on demand for any costs that may be incurred by Landlord in
connection with an Hypothecation, including legal costs incurred in connection with the granting or
denial of any requested consent. Landlord’s consent to one or more Transfers or Hypothecations
shall not operate to waive Tenant’s obligation to obtain Landlord’s consent to other Transfers or
Hypothecations nor constitute consent to an assignment or other Transfer following foreclosure of
any permitted lien, mortgage or other encumbrance. If Tenant is a corporation, limited liability
company, unincorporated association, partnership or other legal entity, the sale, assignment,
transfer or hypothecation of any stock, membership or other ownership interest in such entity
(whether occurring at one time or over a period of time) in the aggregate of more than fifty
percent (50%) (determined cumulatively) shall be deemed an assignment of this Lease; in the case of
a partnership, any withdrawal or substitution (whether occurring at one time or over a period of
time) of any partners owning fifty percent (50%) or more (cumulatively) of the partnership, or the
dissolution of the partnership shall be deemed an assignment of this Lease; provided that, subject
to Section 17.D below, the foregoing provisions of this sentence shall not apply to a transfer of
stock in a corporation whose stock is publicly traded on a public stock exchange. If Tenant is a
corporation whose stock is not publicly traded on a public stock exchange, any dissolution, merger,
consolidation or reorganization of Tenant shall be deemed a Transfer.

     B. Assignment or Subletting Consideration: Landlord and Tenant hereby agree that fifty
percent (50%) of any rent or other economic consideration (including without limitation, payments
for trade fixtures and personal property in excess of the fair market value thereof, stock,
warrants, and options) in excess of the Base Monthly Rent payable hereunder (after deducting
therefrom Reasonable Transfer Costs (defined below)) (i) realized by Tenant in connection with any
Transfer by Tenant, and/or (ii) realized by a subtenant or any other person or entity (other than
Tenant) (any such subtenant, person or entity being a “Subsequent Transferor”) in connection with a
sublease, assignment or other Transfer by such Subsequent Transferor, shall be paid by Tenant to
Landlord promptly after such amounts are paid to Tenant or a Subsequent Transferor, regardless of
the amount of subrent the

Page 15

 

Subsequent Transferor pays to Tenant or any prior Subsequent Transferor.
As used in this Section 17.B, “Reasonable Transfer Costs” shall mean the following costs, to the
extent reasonably incurred in connection with the Transfer in question: (i) advertising costs and
brokerage commissions payable to unaffiliated third parties, and (ii) tenant improvement costs
incurred solely in connection with such Transfer. In the case of a Transfer other than an
assignment of Tenant’s entire interest in the Lease and Premises, Reasonable Transfer Costs shall
be amortized on a straight line basis, without interest, over the initial term of the Transfer.
Tenant’s obligation to pay over Landlord’s portion of the consideration constitutes an obligation
for additional rent hereunder. The above provisions relating to Landlord’s right to terminate the
Lease and relating to the allocation of excess rent are independently negotiated terms of the Lease
which constitute a material inducement for the Landlord to enter into the Lease, and are agreed by
the Parties to be commercially reasonable. No Transfer by Tenant shall relieve it of any
obligation under this Lease. Any Transfer which conflicts with the provisions of this Lease shall
be void.

     C. No Release: Any Transfer shall be made only if and shall not be effective until the
transferee shall execute, acknowledge, and deliver to Landlord an agreement, in form and substance
satisfactory to Landlord, whereby the transferee shall assume all the obligations of this Lease on
the part of Tenant to be performed or observed to the extent of the interest being transferred and
shall be subject to all the covenants, agreements, terms, provisions and conditions in this Lease
to the extent applicable to the interest being transferred. Notwithstanding any Transfer and the
acceptance of rent or other sums by Landlord from any transferee, Tenant and any guarantor shall
remain fully liable for the payment of Base Monthly Rent and additional rent due, and to become due
hereunder, for the performance of all the covenants, agreements, terms, provisions and conditions
contained in this Lease on the part of Tenant to be performed and for all acts and omissions of any
transferee or any other person claiming under or through any transferee that shall be in violation
of any of the terms and conditions of this Lease, and any such violation shall be deemed a
violation by Tenant. Tenant shall indemnify, defend and hold Landlord harmless from and against
all losses, liabilities, damages, costs and expenses (including reasonable attorney fees) resulting
from any claims that may be made against Landlord by the proposed transferee or by any real estate
brokers or other persons claiming compensation in connection with the proposed Transfer.

     D. Reorganization of Tenant: Notwithstanding any other provision of this Lease, the
provisions of this Section 17.D shall apply if Tenant is a publicly-held corporation and: (i)
there is a dissolution, merger, consolidation, or other reorganization of or affecting Tenant,
where Tenant is not the surviving corporation, or there is a sale of all or substantially all of
the assets of Tenant, or (ii) there is a sale, cancellation, surrender, exchange, conversion or any
other transfer of stock involving or consisting of more than fifty percent (50%) of the total
combined voting power of all classes of Tenant’s capital stock issued, outstanding and entitled to
vote for the election of directors, or there is any merger, consolidation or other reorganization
of or affecting Tenant, whether the foregoing occurs in a single transaction or in multiple steps,
and after any one or more of such events Tenant’s stock is no longer publicly traded. In a
transaction under clause (i), the surviving or acquiring corporation or entity (“Surviving Entity”)
shall promptly execute and deliver to Landlord an agreement in form reasonably satisfactory to
Landlord under which the Surviving Entity assumes the obligations of Tenant hereunder. In a
transaction or series of transactions under clause (ii) of this Section 17.D, the entities which as
a result of such transaction(s) own a greater than fifty percent (50%) interest in Tenant
(including, without limitation as a result of a verse triangular merger or a triangular merger)
(collectively the “Acquiring Entity”) shall promptly execute and deliver to Landlord a guaranty of
lease in form reasonably satisfactory to Landlord under which the Acquiring Entity guarantees the
full payment and performance of the obligations of Tenant under the Lease (“Lease Guaranty”). The
foregoing notwithstanding, in the event the Surviving Entity or Acquiring Entity is itself not a
publicly-traded corporation, but is instead the subsidiary of a publicly-traded corporation (or a
subsidiary of a subsidiary of a publicly-traded corporation, or a subsidiary in a chain of entities
in which one or more parent corporations are publicly traded), then each publicly-traded parent
corporation in such chain shall be required to execute and deliver to Landlord the Lease Guaranty.
In addition, in the event that after such acquisition Tenant no longer prepares audited financial
statements, then in addition to the financial statements required to be delivered by Tenant
hereunder, the entity required to execute the Lease Guaranty shall provide Landlord its audited
financial statements at the times and in the manner required of Tenant hereunder. It is the intent
of the parties that after such any transaction or series of

Page 16

 

transactions described in this Section
17.D above, Landlord shall be entitled to rely on the creditworthiness of publicly-traded
corporations and to receive audited financial information from publicly-traded corporations.

     E. Permitted Transfers: Notwithstanding anything contained in this Section 17, so long as
Tenant otherwise complies with the provisions of this Section 17, Tenant may enter into any of the
following Transfers (a “Permitted Transfer”) without Landlord’s prior consent, and Landlord shall
not be entitled to terminate the Lease or to receive any part of any subrent resulting therefrom
that would otherwise be due pursuant to Sections 17.A and 17.B. Tenant may sublease all or part of
the Premises or assign its interest in this Lease to (i) any corporation which controls, is
controlled by, or is under common control with the original Tenant to this Lease by means of an
ownership interest of more than fifty percent (50%); (ii) a corporation which results from a
merger, consolidation or other reorganization in which Tenant is not the surviving corporation, so
long as the surviving corporation has a net worth at the time of such assignment or sublease that
is equal to or greater than the net worth of Tenant immediately prior to such transaction, and
(iii) a corporation which purchases or otherwise acquires all or substantially all of the assets of
Tenant so long as such acquiring corporation has a net worth at the time of such assignment or
sublease that is equal to or greater than the net worth of Tenant immediately prior to such
transaction.

     F. Effect of Default: In the event of Tenant’s default, Tenant hereby assigns all amounts due
to Tenant from any Transfer as security for performance of Tenant’s obligations under this Lease,
and Landlord may collect such amounts as Tenant’s attorney-in-fact, except that Tenant may collect
such amounts unless a default occurs as described in Section 13 above. A termination of the Lease
due to Tenant’s default shall not automatically terminate a Transfer then in existence; rather at
Landlord’s election: (i) such Transfer shall survive the Lease termination; (ii) the transferee
shall attorn to Landlord, and (iii) Landlord shall undertake the obligations of Tenant under the
transfer agreement; except that Landlord shall not be liable for prepaid rent, security deposits or
other defaults of Tenant to the transferee, or for any acts or omissions of Tenant and Tenant’s
Agents.

     G. Conveyance by Landlord: In the event of any transfer of Landlord’s interest in this Lease,
the Landlord herein named (and in case of any subsequent transfer, the then transferor) shall be
automatically freed and relieved from and after the date of such transfer of all liability for the
performance of any covenants or obligations on the part of Landlord contained in this Lease
thereafter to be performed; provided, however, that any funds in the hands of Landlord or the then
transferor at the time of such transfer, in which Tenant has an interest shall be turned over to
the transferee and any amount then due and payable to Tenant by Landlord or the then transferor
under any provision of this Lease shall be paid to Tenant; and provided, further, that upon any
such transfer, the transferee shall be deemed to have assumed, subject to the limitations of this
Section 17, all of the agreements, covenants and conditions in this Lease to be performed on the
part of Landlord, it being intended hereby that the covenants and obligations contained in this
Lease to be performed on the part of Landlord shall, subject as aforesaid, be binding on each
Landlord, its successors and assigns, only during its period of ownership.

     H. Successors and Assigns: Subject to the provisions this Section 17, the covenants and
conditions of this Lease shall apply to and bind the heirs, successors, executors, administrators
and assigns of all Parties hereto; and all parties hereto comprising Tenant shall be jointly and
severally liable hereunder.

     I. Sublease Requirements: If Landlord consents to any sublet of the premises by Tenant to an
approved Subtenant (“Subtenant”), every sublet transaction shall be evidenced by a written sublease
between Tenant and Subtenant (the “Sublease”). The Sublease shall comply with the following
requirements: (i) the form of the Sublease and the terms and conditions thereof shall be subject
to Landlord’s approval which shall not be withhold unreasonably; (ii) the Sublease shall provide
that it is subject to and shall incorporate by reference all of the terms and conditions of this
Lease, except those terms and conditions relating to Rent, Additional Rent, and any other amount
due under this Lease; (iii) the Sublease shall provide that the Subtenant shall have no right to
exercise any option or other right granted to Tenant in this Lease; (iv) the Sublease shall contain
a waiver of subrogation against Landlord and shall require Subtenant’s insurance policies to
acknowledge such waiver of subrogation; (v) the Sublease shall provide that all requirements of
this Lease applicable to subleases shall be applicable to sub-subleases; (vi) the Sublease shall
require Subtenant, acting through Tenant, to obtain Landlord’s prior written approval, to any
alteration to the Premises to the same extent Tenant is

Page 17

 

required by this Lease to obtain such
consent; (vii) the Sublease shall require Subtenant to send Landlord copies of any and all notices
concerning the Premises that Subtenant is obligated to provide to Tenant and Tenant to send
Landlord copies of any and all notices concerning the Premises that Tenant is obligated to provide
to Subtenant; and (viii) the Sublease shall provide that, at Landlord’s option, the Sublease shall
not terminate in the event that this Lease terminates and shall require Subtenant to execute an
attornment agreement if Landlord, in its sole and absolute discretion, shall elect to have the
Sublease continue beyond the date of termination of this Lease.

18. OPTION TO EXTEND THE LEASE TERM:

     A. Grant and Exercise of Option: Landlord grants to Tenant, subject to the terms and
conditions set forth in this Section 18.A, an option (“Option”) to extend the Lease Term for an
additional term (the “Option Term”) of sixty (60) months. The Option shall be exercised, if at
all, by written notice to Landlord no earlier than eighteen (18) months prior to the date the Lease
Term would expire but for such exercise but no later than twelve (12) months prior to the date the
Lease Term would expire but for such exercise, time being of the essence for the giving of such
notice. If Tenant exercises the Option, all of the terms, covenants and conditions of this Lease
shall apply except for the grant of additional Options pursuant to this Section, provided that Base
Monthly Rent for the Premises payable by Tenant during the Option Term shall be the greater of (i)
the initial Base Monthly Rent payable under this Lease, and (ii) ninety five percent (95%) of the
Fair Market Rental, as hereinafter defined. Notwithstanding anything herein to the contrary, (i)
if Tenant is in monetary or material non-monetary default under any of the terms, covenants or
conditions of this Lease either at the time Tenant exercises the Option or at any time thereafter
prior to the commencement date of the Option Term, or (ii) if the net worth of Tenant as reported
in Tenant’s most recent financial statements is less than the net worth of Tenant as of the date of
execution of this Lease, then Landlord shall have, in addition to all of Landlord’s other rights
and remedies provided in this Lease, the right to terminate the Option upon notice to Tenant, in
which event the Lease Term shall not be extended pursuant to this Section 18.A. As used herein,
the term “Fair Market Rental” is defined as the rental and all other monetary payments, including
any escalations and adjustments thereto (including without limitation Consumer Price Indexing) that
Landlord could obtain during the Option Term from a third party desiring to lease the Premises,
based upon the (i) current use and other potential uses of the Premises, as determined by the rents
then obtainable for new leases of space comparable in age and quality to the Premises in the same
real estate submarket as the Building and (ii) the credit standing and financial stature of the
Tenant. The appraisers shall be instructed that the foregoing five percent (5.0%) discount is
intended to offset comparable rents that include the following costs which Landlord will not incur
in the event Tenant exercises its option (i) brokerage commissions, (ii) tenant improvement or
relocation allowances, (iii) vacancy costs, or (iv) other concessions or inducements.

     B. Determination of Fair Market Rental: If Tenant exercises the Option, Landlord shall send
Tenant a notice setting forth the Fair Market Rental for the Option Term within thirty (30) days
following the Exercise Date. If Tenant disputes Landlord’s determination of Fair Market Rental for
the Option Term, Tenant shall, within thirty (30) days after the date of Landlord’s notice setting
forth Fair Market Rental for the Option Term, send to Landlord a notice stating that Tenant either
elects to terminate its exercise of the Option, in which event the Option shall lapse and this
Lease shall terminate on the Expiration Date, or that Tenant disagrees with Landlord’s
determination of Fair Market Rental for the Option Term and elects to resolve the disagreement as
provided in Section 18.C below. If Tenant does not send Landlord a notice as provided in the
previous sentence, Landlord’s determination of Fair Market Rental shall be the Base Monthly Rent
payable by Tenant during the Option Term. If Tenant elects to resolve the disagreement as provided
in Section 18.C and such procedures are not concluded prior to the commencement date of the Option
Term, Tenant shall pay to Landlord as Base Monthly Rent the Fair Market Rental as determined by
Landlord in the manner provided above. If the Fair Market Rental as finally determined pursuant to
Section 18.C is greater than Landlord’s determination, Tenant shall pay Landlord the difference
between the amount paid by Tenant and the Fair Market Rental as so determined in Section 18.C
within thirty (30) days after such determination. If the Fair Market Rental as finally determined
in Section 18.C. is less than Landlord’s determination, the difference between the amount paid by
Tenant and the Fair Market Rental as so determined in Section 18.C shall be credited against the
next installments of Base Monthly Rent due from Tenant to Landlord hereunder.

Page 18

 

     C. Resolution of a Disagreement over the Fair Market Rental: Any disagreement regarding Fair
Market Rental shall be resolved as follows:

          1. Within thirty (30) days after Tenant’s response to Landlord’s notice setting forth the Fair
Market Rental, Landlord and Tenant shall meet at a mutually agreeable time and place, in an attempt
to resolve the disagreement.

          2. If within the 30-day period referred to above, Landlord and Tenant cannot reach agreement
as to Fair Market Rental, each party shall select one appraiser to determine Fair Market Rental.
Each such appraiser shall arrive at a determination of Fair Market Rental and submit their
conclusions to Landlord and Tenant within thirty (30) days after the expiration of the 30-day
consultation period described above.

          3. If only one appraisal is submitted within the requisite time period, it shall be deemed as
Fair Market Rental. If both appraisals are submitted within such time period and the two
appraisals so submitted differ by less than ten percent (10%), the average of the two shall be
deemed as Fair Market Rental. If the two appraisals differ by more than 10%, the appraisers shall
immediately select a third appraiser who shall, within thirty (30) days after his selection, make
and submit to Landlord and Tenant a determination of Fair Market Rental. This third appraisal will
then be averaged with the closer of the two previous appraisals and the result shall be Fair Market
Rental.

          4. All appraisers specified pursuant to this Section shall be members of the American
Institute of Real Estate Appraisers with not less than ten (10) years experience appraising office
and industrial properties in the Santa Clara Valley. Each party shall pay the cost of the
appraiser selected by such party and one-half of the cost of the third appraiser.

     D. Personal to Tenant: All Options provided to Tenant in this Lease are personal and granted
to Terayon Communication Systems, Inc. and are not exercisable by any third party should Tenant
assign or sublet all or a portion of its rights under this Lease, unless Landlord consents to
permit exercise of any option by any assignee or subtenant, in Landlord’s sole and absolute
discretion. In the event Tenant has multiple options to extend this Lease, a later option to
extend the Lease cannot be exercised unless the prior option has been properly exercised.

19. GENERAL PROVISIONS:

     A. Attorney’s Fees: In the event a suit or alternative form of dispute resolution is brought
for the possession of the Premises, for the recovery of any sum due hereunder, to interpret the
Lease, or because of the breach of any other covenant herein; then the losing party shall pay to
the prevailing party reasonable attorney’s fees including the expense of expert witnesses,
depositions and court testimony as part of its costs which shall be deemed to have accrued on the
commencement of such action. The prevailing party shall also be entitled to recover all costs and
expenses including reasonable attorney’s fees incurred in enforcing any judgment or award against
the other party. The foregoing provision relating to post-judgment costs is severable from all
other provisions of this Lease.

     B. Authority of Parties: Tenant represents and warrants that it is duly formed and in good
standing, and is duly authorized to execute and deliver this Lease on behalf of said corporation,
in accordance with a duly adopted resolution of the Board of Directors of said corporation or in
accordance with the by-laws of said corporation, and that this Lease is binding upon said
corporation in accordance with its terms. At Landlord’s request, Tenant shall provide Landlord
with corporate resolutions or other proof in a form acceptable to Landlord, authorizing the
execution of the Lease.

     C. Brokers: Except for Cornish & Carey Commercial/ONCOR International, which is acting as
Tenant’s broker, each party hereunder represents that it has not utilized or contacted a real
estate broker or finder with respect to this Lease and agrees to indemnify, defend and hold the
other party harmless against any claim, cost, liability or cause of action asserted by any other
broker or finder claiming through such indemnifying party.

     D. Choice of Law: This Lease shall be governed by and construed in accordance with California
law. Except as provided in Section 19.E below, venue shall be Santa Clara County.

     E. Dispute Resolution: Landlord and Tenant and any other party that may become a party to
this Lease or be deemed a party to this Lease including any subtenants agree that, except for any

Page 19

 

or breach of this Lease, including any claim based on contract,
tort, or statute, shall be resolved at the request of any party to this agreement through a
two-step dispute resolution process administered by J.A.M.S. or another judicial mediation service
mutually acceptable to the parties located in Santa Clara County, California. The dispute
resolution process shall involve first, mediation, followed, if necessary, by final and binding
arbitration administered by and in accordance with the then existing rules and practices of
J.A.M.S. or other judicial mediation service selected. In the event of any dispute subject to this
provision, either party may initiate a request for mediation and the parties shall use reasonable
efforts to promptly select a J.A.M.S. mediator and commence the mediation. In the event the
parties are not able to agree on a mediator within thirty (30) days, J.A.M.S. or another judicial
mediation service mutually acceptable to the parties shall appoint a mediator. The mediation shall
be confidential and in accordance with California Evidence Code § 1119 et. seq. The mediation
shall be held in Santa Clara County, California and in accordance with the existing rules and
practice of J.A.M.S. (or other judicial and mediation service selected). The parties shall use
reasonable efforts to conclude the mediation within sixty (60) days of the date of either party’s
request for mediation. The mediation shall be held prior to any arbitration or court action (other
than a claim by Landlord for unlawful detainer or any claim within the jurisdiction of the small
claims court which are not subject to this mediation/arbitration provision and may be filed
directly with a court of competent jurisdiction). In order for the prevailing party to be entitled
to the payment of attorney’s fees, the prevailing party must have followed the provisions of this
Section 19.E. and have attempted to mediate any dispute prior to invoking arbitration.

IF A MEDIATION IS CONDUCTED BUT IS UNSUCCESSFUL, IT SHALL BE FOLLOWED BY FINAL AND BINDING
ARBITRATION ADMINISTERED BY AND IN ACCORDANCE WITH THE THEN EXISTING
RULES AND PRACTICES OF J.A.M.S. OR THE OTHER JUDICIAL AND MEDIATION SERVICE SELECTED, AND JUDGMENT UPON ANY AWARD RENDERED BY THE
ARBITRATOR(S) MAY BE ENTERED BY ANY STATE OR FEDERAL COURT HAVING JURISDICTION THEREOF AS PROVIDED
BY CALIFORNIA CODE OF CIVIL PROCEDURE SECTION 1280 ET. SEQ., AS SAID STATUTES THEN APPEAR,
INCLUDING ANY AMENDMENTS TO SAID STATUTES OR SUCCESSORS TO SAID STATUTES OR AMENDED STATUTES,
EXCEPT THAT IN NO EVENT SHALL THE PARTIES BE ENTITLED TO PROPOUND INTERROGATORIES OR REQUEST FOR
ADMISSIONS DURING THE ARBITRATION PROCESS. THE ARBITRATOR SHALL BE A RETIRED JUDGE OR A LICENSED
CALIFORNIA ATTORNEY. THE VENUE FOR ANY SUCH ARBITRATION OR MEDIATION SHALL BE IN SANTA CLARA
COUNTY, CALIFORNIA.

LANDLORD:  JMS  TENANT:  JDC 

     F. Entire Agreement: This Lease and the exhibits attached hereto contain all of the
agreements and conditions made between the Parties hereto and may not be modified orally or in any
other manner other than by written agreement signed by all parties hereto or their respective
successors in interest. This Lease supersedes and revokes all previous negotiations, letters of
intent, lease proposals, brochures, agreements, representations, promises, warranties, and
understandings, whether oral or in writing, between the parties or their respective

Page 20

 

representatives
or any other person purporting to represent Landlord or Tenant.

     G. Entry by Landlord: Upon twenty-four (24) hours’ prior notice to Tenant and subject to
Tenant’s reasonable security regulations and procedures, Tenant shall permit Landlord and his
agents to enter into and upon the Premises at all reasonable times, and without any rent abatement
or reduction or any liability to Tenant for any loss of occupation or quiet enjoyment of the
Premises thereby occasioned, for the following purposes and actions, so long as such actions do not
have a material adverse effect on Tenant’s parking, use, or access to the Building: (i) inspecting
and maintaining the Premises; (ii) making repairs, alterations or additions to the Premises; (iii)
erecting additional building(s) and improvements on the land where the Premises are situated or on
adjacent land owned by Landlord; (iv) performing any obligations of Landlord under the Lease
including remediation of Hazardous Materials if determined to be the responsibility of Landlord,
(v) posting and keeping posted thereon notices of non-responsibility for any construction,
alteration or repair thereof, as required or permitted by any law; and (vi) showing the Premises to
Landlord’s or the Master Landlord’s existing or potential successors, purchaser, tenants and
lenders. Tenant shall permit Landlord and his agents, at any time within twelve (12) months prior
to the Expiration Date (or at any time during the Lease if Tenant is in default hereunder), to
place upon the Premises “For Lease” signs and exhibit the Premises to real estate brokers and
prospective tenants at reasonable hours.

     H. Estoppel Certificates: At any time during the Lease Term, Tenant shall, within ten (10)
days following written notice from Landlord, execute and deliver to Landlord a written statement
certifying, if true, the following: (i) that this Lease is unmodified and in full force and effect
(or, if modified, stating the nature of such modification); (ii) the date to which rent and other
charges are paid in advance, if any; (iii) acknowledging that there are not, to Tenant’s knowledge,
any uncured defaults on Landlord’s part hereunder (or specifying such defaults if they are
claimed); and (iv) such other information as Landlord may reasonably request. Any such statement
may be conclusively relied upon by any prospective purchaser or encumbrancer of Landlord’s interest
in the Premises. Tenant’s failure to deliver such statement within such time shall be conclusive
upon the Tenant that this Lease is in full force and effect without modification, except as may be
represented by Landlord, and that there are no uncured defaults in Landlord’s performance. Tenant
agrees to provide, within five (5) days of Landlord’s request, Tenant’s most recent three (3) years
of audited financial statements for Landlord’s use in financing or sale of the Premises or
Landlord’s interest therein.

     I. Exhibits: All exhibits referred to are attached to this Lease and incorporated by
reference.

     J. Interest: All rent due hereunder, if not paid when due, shall bear interest at the rate of
the Reference Rate published by Bank of America, San Francisco Branch, plus two percent (2%) per
annum from that date until paid in full (“Agreed Interest Rate”). This provision shall survive the
expiration or sooner termination of the Lease. Despite any other provision of this Lease, the
total liability for interest payments shall not exceed the limits, if any, imposed by the usury
laws of the State of California. Any interest paid in excess of those limits shall be refunded to
Tenant by application of the amount of excess interest paid against any sums outstanding in any
order that Landlord requires. If the amount of excess interest paid exceeds the stuns outstanding,
the portion exceeding those sums shall be refunded in cash to Tenant by Landlord. To ascertain
whether any interest payable exceeds the limits imposed, any non-principal payment (including late
charges) shall be considered to the extent permitted by law to be an expense or a fee, premium, or
penalty rather than interest.

     K. Modifications Required by Lender: If any lender of Landlord or ground lessor of the
Premises requires a modification of this Lease that will not increase Tenant’s cost or expense or
materially or adversely change Tenant’s rights and obligations, this Lease shall be so modified and
Tenant shall execute whatever documents are required and deliver them to Landlord within ten (10)
days after the request.

     L. No Presumption Against Drafter: Landlord and Tenant understand, agree and acknowledge that
this Lease has been freely negotiated by both Parties; and that in any controversy, dispute, or
contest over the meaning, interpretation, validity, or enforceability of this Lease or any of its
terms or conditions, there shall be no inference, presumption, or conclusion drawn whatsoever
against either party by virtue of that party having drafted this Lease or any portion thereof.

     M. Notices: All notices, demands, requests, or consents required to be given under this Lease
shall be sent in writing by U.S. certified mail, return

Page 21

 

receipt requested, or by personal delivery
addressed to the party to be notified at the address for such party specified in Section 1 of this
Lease, or to such other place as the party to be notified may from time to time designate by at
least fifteen (15) days prior notice to the notifying party. When this Lease requires service of a
notice, that notice shall replace rather than supplement any equivalent or similar statutory
notice, including any notices required by Code of Civil Procedure Section 1161 or any similar or
successor statute.

     N. Property Management: In addition, Tenant agrees to pay Landlord along with the expenses to
be reimbursed by Tenant a monthly fee for management services rendered by either Landlord or a
third party manager engaged by Landlord (which may be a party affiliated with Landlord), in the
amount of three percent (3%) of the Base Monthly Rent.

     O. Rent: All monetary sums due from Tenant to Landlord under this Lease, including, without
limitation those referred to as “additional rent”, shall be deemed as rent.

     P. Representations: Except for the provisions of this Lease, Tenant acknowledges that neither
Landlord nor any of its employees or agents have made any agreements, representations, warranties
or promises with respect to the Premises or with respect to present or future rents, expenses,
operations, tenancies or any other matter. Except as herein expressly set forth herein, Tenant
relied on no statement of Landlord or its employees or agents for that purpose.

     Q. Rights and Remedies: Subject to Section 14 above, all rights and remedies hereunder are
cumulative and not alternative to the extent permitted by law, and are in addition to all other
rights and remedies in law and in equity.

     R. Severability: If any term or provision of this Lease is held unenforceable or invalid by a
court of competent jurisdiction, the remainder of the Lease shall not be invalidated thereby but
shall be enforceable in accordance with its terms, omitting the invalid or unenforceable term.

     S. Submission of Lease: Submission of this document for examination or signature by the
parties does not constitute an option or offer to lease the Premises on the terms in this document
or a reservation of the Premises in favor of Tenant. This document is not effective as a lease or
otherwise until executed and delivered by both Landlord and Tenant.

     T. Subordination: This Lease is subject and subordinate to ground and underlying leases,
mortgages and deeds of trust (collectively “Encumbrances”) which may now affect the Premises, to
any covenants, conditions or restrictions of record, and to all renewals, modifications,
consolidations, replacements and extensions thereof; provided, however, if the holder or holders of
any such Encumbrance (“Holder”) require that this Lease be prior and superior thereto, within seven
(7) days after written request of Landlord to Tenant, Tenant shall execute, have acknowledged and
deliver all documents or instruments, in the form presented to Tenant, which Landlord or Holder
deems necessary or desirable for such purposes. Landlord shall have the right to cause this Lease
to be and become and remain subject and subordinate to any and all Encumbrances which are now or
may hereafter be executed covering the Premises or any renewals, modifications, consolidations,
replacements or extensions thereof, for the full amount of all advances made or to be made
thereunder and without regard to the time or character of such advances, together with interest
thereon and subject to all the terms and provisions thereof, provided only, that in the event of
termination of any such lease or upon the foreclosure of any such mortgage or deed of trust, Holder
agrees to recognize Tenant’s rights under this Lease as long as Tenant is not then in default and
continues to pay Base Monthly Rent and additional rent and observes and performs all required
provisions of this Lease. Within ten (10) days after Landlord’s written request, Tenant shall
execute any documents required by Landlord or the Holder to make this Lease subordinate to any lien
of the Encumbrance, subject to Holder’s agreement to recognize Tenant’s rights as set forth in the
preceding sentence. If Tenant fails to do so, then in addition to such failure constituting a
default by Tenant, it shall be deemed that this Lease is so subordinated to such Encumbrance.
Notwithstanding anything to the contrary in this Section, Tenant hereby attorns and agrees to
attorn to any entity purchasing or otherwise acquiring the Premises at any sale or other proceeding
or pursuant to the exercise of any other rights, powers or remedies under such Encumbrance. Within
sixty (60) days after the Commencement Date, Landlord shall obtain a subordination and
nondisturbance agreement from all existing Holders in a form mutually and reasonably agreeable to
all parties hereunder.

     U. Survival of Indemnities: All indemnification, defense, and hold harmless obligations of
Landlord and Tenant under this Lease

Page 22

 

shall survive the expiration or sooner termination of the
Lease.

     V. Time: Time is of the essence hereunder.

     W. Waiver of Right to Jury Trial: Landlord and Tenant waive their respective rights to trial
by jury of any contract or tort claim, counterclaim, cross-complaint, or cause of action in any
action, proceeding, or hearing brought by either party against the other on any matter arising out
of or in any way connected with this Lease, the relationship of Landlord and Tenant, or Tenant’s
use or occupancy of the Premises, including any claim of injury or damage or the enforcement of any
remedy under any current or future law, statute, regulation, code, or ordinance.

Exhibit 10.28

TRIPLE NET SUB-SUBLEASE

          This SUB-SUBLEASE (this “Sub-sublease”) is entered into as of June 27, 2006 (the “Execution
Date”) by and between TERAYON COMMUNICATION SYSTEMS, INC., a Delaware corporation
(“Sub-sublandlord”), and CITRIX SYSTEMS, INC., a Delaware corporation (“Sub-subtenant”).

1. BACKGROUND.

          1.1 Premises. Sobrato Development Companies #961, a California limited partnership
(successor-in-interest to Sobrato Interests III, a California limited partnership (“Original
Sobrato”)) (“Master Landlord”), holds fee simple title to a parcel of land located at 4988
Great America Parkway, Santa Clara, California, as more particularly described in Exhibit A
attached hereto, including a five (5) story building located on such land, which building
contains approximately One Hundred Forty Thousand Nine Hundred Sixty-Five (140,965) square feet
(the “Building,” together with such land is sometimes collectively referred to herein as the
“Property”). The “Premises,” as more particularly described in Exhibit B attached hereto, shall
mean the Property together with: (a) all other buildings, structures and improvements, if any,
located on the Property; and (b) the appurtenances of Master Landlord and all the estate and
rights of Master Landlord in and to the Property.

          1.2 Master Lease. Original Sobrato entered into a Lease, dated September 18, 1996 (the
“Master Lease”), with VeriFone, Inc., a California corporation, predecessor-in-interest to
Hewlett-Packard Company, a Delaware corporation (“Sublandlord”), pursuant to which Master
Landlord leased the Premises to Sublandlord.

          1.3 Sublease. Sublandlord and Sub-sublandlord entered into a Triple Net Sublease dated
April 1, 2002 (the “Sublease”), pursuant to which Sublandlord subleases the Premises to
Sub-sublandlord. Sub-subtenant acknowledges its receipt in April, 2006, from Sub-sublandlord,
of a copy of the Master Lease, the Sublease, and an itemized triple-net (NNN) expense report
including all utility and janitorial costs, for the Premises for each month of calendar year
2005. Sub-sublandlord represents that it has provided Sub-subtenant with, to best of
Sub-sublandlord’s knowledge, true, complete and accurate copies of the Master Lease and Sublease
in Sub-sublandlord’s possession.

          1.4 Desire to Sub-sublease. Sub-sublandlord desires to sub-sublease the Premises to
Sub-subtenant, and Sub-subtenant desires to sub-sublease the Premises from Sub-sublandlord.

                    NOW, THEREFORE, in consideration of the covenants and agreements of the parties contained in
this Sub-sublease, and for other good and valuable consideration, the receipt and sufficiency of
which are conclusively acknowledged by both parties, Sub-sublandlord and Sub-subtenant agree as set
forth below.

2. DEMISING OF PREMISES. Sub-sublandlord hereby sub-subleases the Premises to Sub-subtenant, and
Sub-subtenant hereby sub-subleases the Premises from Sub-sublandlord, for the Sub-sublease Term (as
defined below in Section 3), upon the terms and conditions of this Sub-sublease.

 

 

3. SUB-SUBLEASE TERM. Subject to Sections 4, 5 and 6 below, the term of this Sub-sublease (the
“Sub-sublease Term”) shall commence on or before September 18, 2006 (the “Targeted Delivery Date”),
and shall expire on October 31, 2009 (the “Expiration Date”), unless terminated sooner in
accordance with the terms of this Sub-sublease. On the Targeted Delivery Date Sub-sublandlord
shall deliver sole and exclusive possession, free of all parties in possession, of all the
Premises. The date on which Sub-sublandlord actually delivers sole and exclusive possession of all
the Premises shall constitute the commencement date (the “Commencement Date”). Whether or not the
Targeted Delivery Date actually precedes or coincides with Sub-sublandlord’s delivery of the
possession of all of the Premises, the parties shall confirm the Commencement Date by a letter
agreement substantially in the form of Exhibit C attached hereto, within five (5) business days
after the Commencement Date occurs, and Base Rent (as defined in Subsection 7.1 below) shall be due
and payable in accordance with Subsection 7.2 and Sub-subtenant shall continue paying Additional
Rent (as defined in Subsection 7.3 below).

4. CONDITIONS PRECEDENT TO EFFECTIVE SUB-SUBLEASE COMMENCEMENT DATE. Notwithstanding the
Sub-sublandlord and Sub-subtenant’s full execution of this Sub-sublease, the Sub-sublease Term
shall not commence unless all of the following eight (8) conditions precedent (the “Conditions
Precedent”) have occurred on or before June 23, 2006 (the “Conditions Precedent Satisfaction
Date”). If any of the Conditions Precedent fail to occur by the Conditions Precedent Satisfaction
Date (subject to force majeure as set forth in Subsection 12.3 below), the Targeted Delivery Date
shall be extended one business day for each business day of delay in the occurrence of all the
Conditions Precedent. If any of the Conditions Precedent fail to occur by June 30, 2006, this
Sub-sublease shall terminate, which termination shall render all terms and conditions hereunder
null and void, unless the Sub-sublandlord and Sub-subtenant mutually agree in writing to extend
such date.

          4.1 Execution of this Sub-sublease. Sub-sublandlord and Sub-subtenant shall fully execute
this Sub-sublease.

          4.2 Sub-sublandlord’s Replacement Space. Sub-sublandlord and a third-party landlord shall
sign a lease for replacement space, thereby enabling Sub-sublandlord to deliver to Sub-subtenant
the Premises on or before the Targeted Delivery Date.

          4.3 Landlord Consents. Sub-sublandlord shall obtain the written consent to this
Sub-sublease from: (1) the Master Landlord, in a form acceptable to Sub-subtenant, in the
exercise of its reasonable discretion (the “Master Landlord Consent”), and (2) the Sublandlord,
in substantially the form of the attached (the “Sublandlord Consent,” together with the Master
Landlord Consent referred to herein as the “Landlord Consents”). Each of the Landlord Consents
shall include their respective approvals of the TI Plans, pursuant to Subsection 4.4 below.

          4.4 Approval of Sub-subtenant’s Tenant Improvements. Master Landlord, Sublandlord and
Sub-sublandlord shall deliver their reasonable written approval of the initial tenant
improvements proposed by Sub-subtenant for the Premises. Sub-sublandlord acknowledges that
Sub-subtenant delivered its TI Plans on May 12, 2006 to Master Landlord,

2

 

Sublandlord and Sub-sublandlord. Such written approvals of the TI Plans by the Master
Landlord and Sublandlord shall be set forth in their respective Landlord Consents.

          4.5 Release from Master Lease and Sublease Restoration Obligations. Upon written approval
of the TI Plans by Master Landlord: (i) Sub-subtenant shall be released from all restoration
obligations otherwise owed by Sublandlord and/or Sub-sublandlord under the Master Lease or
Sublease; (ii) Sub-sublandlord shall be released from all restoration obligations under the
Sublease; and (iii) Sublandlord shall be released from all restoration obligations under the
Master Lease and Sublease. If Master Landlord does not approve Sub-subtenant’s TI Plans and
Sub-subtenant enters into the Definitive Lease (as defined in Subsection 4.7 below), then, and
only then shall Sub-subtenant assume the restoration obligations of Sublandlord and
Sub-sublandlord.

          4.6 Sublandlord’s Acceptance of Sub-subtenant’s Attornment. Sub-sublandlord shall use
commercially reasonable efforts to obtain from Sublandlord an attornment agreement as contained
in the Sublandlord Consent attached hereto or a separate agreement to the effect that if any
default by Sub-sublandlord under the Sublease causes the Sublease to terminate, Sublandlord will
accept Sub-subtenant’s attornment and honor this Sub-sublease (unless Sub-subtenant is in breach
of this Sub-sublease).

          4.7 Master Landlord’s Acceptance of Sub-subtenant’s Attornment. Sub-sublandlord shall use
commercially reasonable efforts to obtain from Master Landlord the Master Landlord Consent which
will provide that if any default by Sublandlord under the Master Lease causes the Sublease to
terminate, Master Landlord will accept Sub-subtenant’s attornment and honor this Sub-sublease
for the balance of the Sub-sublease Term (unless Sub-subtenant is in breach of this
Sub-sublease).

          4.8 Execution of Lease Agreement by and between Master Landlord and Sub-subtenant. Master
Landlord and Sub-subtenant are contemporaneously negotiating a definitive lease for the Premises
with an effective date on or about November 1, 2009. This definitive lease for the Premises
between Master Landlord and Sub-subtenant shall have been fully executed (the “Definitive
Lease”).

5. DELIVERY OF POSSESSION. (a) Sub-sublandlord shall deliver sole and exclusive possession, free
of all parties in possession, of all the Premises to Sub-subtenant on or before the Targeted
Delivery Date. If Sub-sublandlord does not deliver possession to Sub-subtenant of the Premises, or
any portion thereof, on or before the Targeted Delivery Date, Sub-sublandlord shall pay Base Rent
(as defined in Subsection 7.1 below) and Additional Rent (as defined in Subsection 7.3 below) for
whatever portion of the Premises that Sub-sublandlord then occupies for the period of time it
remains in possession of such space after the Targeted Delivery Date until the date Sub-sublandlord
vacates such space.

          (b) Notwithstanding the foregoing, if for any reason (other than Sub-subtenant’s default
under this Sub-sublease) Sub-sublandlord does not deliver possession of the Premises to
Sub-subtenant on or before October 31, 2006, (the “Vacation Date”), Sub-subtenant shall have the
right to either (i) terminate this Sub-sublease by providing written notice of the same to
Sub-sublandlord within five (5) days after the Vacation Date (“Final Termination Right”), or (ii)

3

 

institute legal or other action of specific performance to require Sub-sublandlord to vacate
the Premises, or any portion thereof, and deliver possession of the same to Sub-subtenant in the
condition required under this Sub-sublease.

6. EARLY OCCUPANCY. Following the Conditions Precedent Satisfaction Date, Sub-subtenant shall have
the right to occupy the fourth (4th) and fifth (5th) floors of the Building,
without paying any Base Rent (as defined in Subsection 7.1 below), but shall pay its pro rata share
(depending on the amount of space in the Building occupied by Sub-subtenant) of Additional Rent (as
defined in Subsection 7.3 below), for the period from the date Sub-subtenant takes possession of
the fourth (4th) and fifth (5th) floors of the Building until the Targeted
Delivery Date. If, prior to the Targeted Delivery Date, Sub-sublandlord vacates the first
(1st) and second (2nd) floors of the Building and delivers the same to
Sub-subtenant for its sole and exclusive occupancy, Sub-subtenant shall have the right to occupy
such floors without paying Base Rent, but shall pay its pro rata share (depending on the amount of
space in the Building occupied by Sub-subtenant) of Additional Rent, for the period from the date
Sub-subtenant takes possession of such floors until the Commencement Date.

7. RENT.

          7.1 Payment; Proration, etc. The parties hereto shall cause Sublandlord to agree in its
Landlord Consent to this Sub-sublease and shall cause Sublandlord to send its monthly invoices
for all rent under the Sublease to each of Sub-sublandlord and Sub-subtenant at the addresses
under Subsection 12.4 below (Notices) showing their respective share of the rent then due.
Sub-sublandlord and Sub-subtenant shall pay all rental payments due hereunder, in accordance
with the payment schedule under Section 3.1 of the Sublease, as evidenced by such invoices,
directly to Sublandlord at 1501 Page Mill Road, MS 1001, Palo Alto, CA 94304, or at such other
address as may be designated in writing by Sublandlord, on the first day of each and every month
of the Sub-sublease Term (except for the first month’s rent which shall be due pursuant to
Subsection 7.2 below) as base monthly rent (“Base Rent”) for the Premises.

Sub-sublandlord shall be responsible to pay Sublandlord directly all rents owed under Section
3.1 of the Sublease less the following rents which shall be paid by Sub-subtenant directly to
Sublandlord:

	 	 	 
	Duration	 	Price/SF/Month/NNN
	From Early Occupancy Date to the Commencement Date
	 	$0 (no Base Rent)
	 
	 	 
	Months 1-12 following the Commencement Date
	 	$1.25
	 
	 	 
	Months 13-24
	 	$1.2875
	 
	 	 
	Months 25 – Expiration Date
	 	$1.33

Fixed rent for partial months at the beginning or end of the Sub-sublease Term shall be prorated
based on the number of days in such month within the Sub-sublease Term divided by thirty (30).

4

 

          7.2 First Month’s Rent. Sub-subtenant shall pay to Sublandlord an amount equal to the
first month’s payable rent no later than five (5) business days after the Commencement Date. If
Sub-subtenant subsequently exercises its Final Termination Right, then such rent shall be
returned to Sub-subtenant.

          7.3 Additional Rent. The parties hereto shall cause Sublandlord to agree in its Landlord
Consent and cause Sublandlord to send its monthly invoices for Additional Rent (as defined in
this Subsection 7.3) directly to Sub-subtenant. During the term of this Sub-sublease and
pursuant to Section 6 above, Sub-subtenant shall pay directly to Sublandlord an amount equal to
all payments of additional rent required to be made by Sublandlord pursuant to the Sublease,
including without limitation operating costs and Maintenance (as defined in Section 6.1 of the
Sublease) costs (“Additional Rent”). Sub-subtenant shall pay each such item of Additional Rent
at the same time as Sub-sublandlord is required to make the corresponding payment under Section
3.3 of the Sublease. Additional Rent for any partial month shall be prorated as set forth in
Subsection 7.1 above.

          7.4 Other Payments Relating to the Premises. Sub-subtenant shall pay any and all other
payments due in accordance with the Sublease and Master Lease with respect to the Premises
during the Sub-sublease Term, but excluding any payments owed by Sublandlord or Sub-sublandlord
for the period prior to the Commencement Date and excluding any liabilities of Sublandlord under
the Sublease arising prior to the Commencement Date. Sub-subtenant shall make all such payments
at the same time as Sub-sublandlord is required to make the corresponding payment under the
Sublease, but in no event shall Sub-subtenant be required to make any such payment earlier than
ten (10) business days after receipt of an invoice from Master Landlord, Sublandlord or
Sub-sublandlord. Any such other payments for any partial month shall be prorated as set forth
in Subsection 7.1 above.

          Anything in this Sub-sublease to the contrary notwithstanding, Sub-subtenant shall not be

9. SUBLEASING COVENANTS.

          9.1 Incorporation of Sublease. The Sublease is hereby incorporated by reference into this
Sub-sublease, except to the extent the Sublease is inconsistent with the express terms of this
Sub-sublease, and, as incorporated, becomes an agreement between Sub-sublandlord and
Sub-subtenant. Wherever this Sub-sublease conflicts with an incorporated term of the Sublease,
this Sub-sublease shall govern, but wherever reasonably possible, such a conflict shall be
resolved by making Sub-subtenant’s obligations under both documents coterminous and exactly the
same. Notwithstanding the early termination of the Sublease or the Master Lease for any reason
whatsoever, the parties hereto shall be bound by the provisions of the Sublease incorporated
herein by this Subsection 9.1. Notwithstanding the foregoing, Sub-subtenant shall not be
subject to, or have any obligations under Sections 7 (“Broker”) and 12 (“Letter of Credit”) of
the Sublease.

          9.2 Defined Terms. Except as otherwise provided in Subsection 9.1 above, each reference to
“Sublessor” in the Sublease shall be deemed replaced by a reference to “Sub-sublandlord.”
Except as otherwise provided in Subsection 9.1 above, each reference to “Sublessee” in the
Sublease shall be deemed replaced by a reference to “Sub-subtenant.” Each reference to the
Sublease shall be deemed, where appropriate, to refer to this Sub-sublease. All other defined
terms shall be deemed appropriately modified to reflect the circumstances of this Sub-sublease.

          9.3 Compliance with Sublease. Subject to the exclusions set out in Subsection 9.1 above,
Sub-subtenant agrees to be bound by and to fully comply with all obligations of Sub-sublandlord
as subtenant under the Sublease, except to the extent that this Sub-sublease expressly requires
Sub-sublandlord to perform any obligations of subtenant under the Sublease.

          9.4 Indemnity.

          (a) Indemnification by Sub-sublandlord. Sub-sublandlord shall indemnify defend
and hold Sub-subtenant harmless from and against any and all claims resulting from
Sub-sublandlord default under this Sub-sublease, the Master Lease, the Sublease or any negligent
acts or omissions or willful misconduct of Sub-sublandlord or by any officer, director,
employee, agent, contractor or authorized representative of Sub-sublandlord.

          (b) Indemnification by Sub-subtenant. Sub-subtenant shall indemnify defend and
hold Sub-sublandlord harmless from and against any and all claims resulting from Sub-subtenant’s
default under this Sub-sublease, the Master Lease, the Sublease or any negligent acts or
omissions or willful misconduct of Sub-subtenant or by any officer, director, employee, agent,
contractor or authorized representative of Sub-subtenant.

          9.5 Rights and Benefits Under Sublease. Sub-subtenant shall have all the rights,
privileges and benefits granted to or conferred upon Sub-sublandlord as subtenant under the
Sublease, provided that Sub-subtenant’s exercise of such rights, privileges and benefits
shall not cause Sub-sublandlord to be in default under the Sublease.

7

 

          9.6 Performance by Master Landlord, Sublandlord and Sub-sublandlord.

               9.6.1 No Sub-sublandlord Obligation. Whenever the Sublease requires Sublandlord to provide
any benefit or service and/or where the Master Lease requires the Master Landlord to provide any
such benefit or service, Sub-subtenant shall be entitled to receive such benefit or service
directly from Sublandlord under the Sublease and (if applicable) from Master Landlord under the
Master Lease. Sub-sublandlord, subject to the obligations as set forth in this Sub-sublease,
shall have no liability to Sub-subtenant, and Sub-subtenant’s obligations under this
Sub-sublease shall not be reduced, restricted, diminished or deferred, on account of
Sub-sublandlord’s failure to provide any service or benefit under the Sublease or Master Lease,
or failure to perform any obligation under the Sublease or Master Lease, unless such failure is
caused by Sub-sublandlord’s default under an obligation under this Sub-sublease.

          9.7 Enforcement by Sub-subtenant. If Sublandlord shall fail or refuse to comply with any
of the terms of the Sublease, or if Master Landlord shall fail or refuse to comply with any of
the terms of the Master Lease, Sub-subtenant shall have the right, upon notice to
Sub-sublandlord and so long as Sub-subtenant shall not be in default under this Sub-sublease (in
the case of non-monetary defaults, beyond applicable cure periods), to exercise, in its own
name, and that of Sub-sublandlord, all the rights available to Sub-sublandlord as subtenant
under the Sublease to enforce performance on the part of Sublandlord thereunder, and to
exercise, in its own name, and that of Sublandlord, all the rights available to Sublandlord as
tenant under the Master Lease to enforce performance on the part of Master Landlord thereunder.

          9.8 Preservation of Sublease. So long as Sub-subtenant is not in default: (i)
Sub-sublandlord shall preserve the Sublease and keep the Sublease in full force and effect
throughout the Sub-sublease Term; (ii) Sub-sublandlord shall not agree to any amendment to the
Sublease; (iii) Sub-sublandlord shall not, without Sub-subtenant’s written consent, exercise any
right to terminate the Sublease (including any right to treat the Sublease as terminated on
account of casualty or condemnation or pursuant to any bankruptcy or insolvency proceeding
affecting Sub-Sublandlord) with respect to any period within the Sub-sublease Term; and (iv)
Sub-sublandlord shall perform all its obligations under the Sublease not assumed by
Sub-subtenant hereunder during the Sub-sublease Term. Prior to entering into any amendment of
the Sublease, Sub-sublandlord shall promptly provide Sub-subtenant with a copy thereof. If the
amendment is an amendment permitted under this Sub-sublease, and Sub-sublandlord enters into
such amendment with Sub-subtenant’s consent, the definition of “Sublease” shall be deemed
modified to reflect such amendment. Sub-sublandlord shall not agree to any amendment to or
modification of the Master Lease, or to any termination of the Master Lease, without
Sub-subtenant’s prior written consent.

          9.9 Approvals. Whenever the Master Lease requires Master Landlord’s approval of or consent
to any matter, Sub-subtenant shall obtain Master Landlord’s approval or consent to such matter.
Whenever the Sublease requires Sublandlord’s approval of or consent to any matter, Sub-subtenant
shall obtain Sublandlord’s approval of or consent to such matter. Notwithstanding the foregoing
the consent or approval of the Master Landlord or Sublandlord under the Master Lease or Sublease
to any matter requiring their respective approvals shall for purposes of this Sub-sublease shall
also constitute the approval or consent of the Sub-sublandlord.

8

 

          9.10 Notices to or From Master Landlord or Sublandlord. Sub-sublandlord and Sub-subtenant
shall immediately provide the other with a copy of any notice or other written communication of
any kind given to or received from Master Landlord or Sublandlord. Sub-sublandlord and
Sub-subtenant shall immediately provide Sublandlord with a copy of any notice or other written
communication of any kind given to or received from Master Landlord or Sublandlord.

          9.11 Representations and Warranties. Sub-sublandlord represents and warrants that the
Sublease is the entire agreement between Sublandlord and Sub-sublandlord relating to Premises
and is in full force and effect, and neither Sublandlord nor Sub-sublandlord is in default
beyond any applicable cure periods under the Sublease.

10. INTERACTION OF ESTATES.

          10.1 Priorities. This Sub-sublease is subject and subordinate to the Master Lease and
Sublease, as amended from time to time in compliance with this Sub-sublease. Notwithstanding
anything to the contrary in the Master Lease or Sublease, Sub-sublandlord shall not have the
right to encumber its leasehold estate during the Sub-sublease Term.

          10.2 No Effect on Master Lease. Notwithstanding anything to the contrary in this
Sub-sublease, the terms and conditions of the Master Lease remain in full force and effect
between Master Landlord and Sublandlord.

11. LEASING COVENANTS.

          11.1 Tenant Improvements. Subject to the provisions of Section 8 above, Sub-subtenant
shall take the Premises in its “AS IS” condition. Sub-subtenant shall have the right to install
additional tenant improvements, subject to Master Landlord’s, Sublandlord’s and
Sub-sublandlord’s approval, not to be unreasonably withheld or delayed. Sub-subtenant shall
have the right to design and construct Sub-subtenant’s tenant improvement work to the Premises,
with all such design and construction plans, as well as Sub-subtenant’s selection of a general
contractor, to be subject to the approval of Master Landlord, Sublandlord and Sub-sublandlord,
not to be unreasonably withheld or delayed. Upon Sub-sublandlord’s delivery of any of the
Premises to Sub-subtenant, Sub-subtenant shall have the right to commence such tenant
improvement work to the Premises previously approved by Master Landlord, Sublandlord and
Sub-sublandlord.

          11.2 Signage. Subject to compliance with all applicable statutes, codes, ordinances,
regulations and other laws, Sub-sublandlord shall approve and cooperate with Sub-subtenant in
Sub-subtenant’s efforts to put its name and logo on the externally visible façade of the

expense, a monument berm sign on the corner of Tasman Drive and Great America Parkway in the
City of Santa Clara, California. Sub-subtenant’s signage placement and installation is subject
to the reasonable approval of Master Landlord and Sublandlord, not to be unreasonably withheld
or delayed, and all their respective compliance with applicable statutes, codes, ordinances,
regulations and other laws.

          11.3 Quiet Enjoyment. So long as Sub-subtenant pays all rental fees in accordance with the
payment schedule reflected in Section 7 above, performs its obligations under this Sub-sublease
(including the Sublease as incorporated by reference), and is not otherwise in default in any
material respect under this Sub-sublease (beyond any applicable cure periods), Sub-sublandlord
shall take no action which would interfere with the right of Sub-subtenant to peaceably have,
hold and enjoy the Premises during the Sub-sublease Term, subject to the terms of this
Sub-sublease.

          11.4 Default; Remedies. Notwithstanding anything to the contrary in this Sub-sublease, if
Sub-subtenant defaults in performance of any obligation under this Sub-sublease (including the
Sublease as incorporated by reference), then Sub-subtenant shall remedy such default within the
applicable cure period (if any) provided for in the Sublease, which period shall automatically
commence to run against Sub-subtenant at the same time it commences to run against
Sub-sublandlord, provided that Sub-sublandlord immediately provides Sub-subtenant with a
copy of Master Landlord’s or Sublandlord’s notice of default, if Master Landlord or Sublandlord
has not already done so. If Sub-subtenant fails to perform its obligations or timely cure any
of its defaults under this Sub-sublease (including the Sublease as incorporated by reference),
then Sub-sublandlord shall be entitled to exercise against Sub-subtenant all remedies provided
for in the Sublease (as incorporated by reference) with respect to Sub-sublandlord’s default
under the Sublease, and any other remedies available at law or in equity.

completion of performance is delayed by reasons of floods, earthquakes or other acts of God,
war, civil commotion, riots, strikes, picketing, or other labor disputes, damage to work in
progress by casualty, or by other cause beyond the reasonable control of the performing party
and occurring without such party’s fault or negligence, including acts within the exclusive
control of Sublandlord, Master Landlord, and/or any other third parties, then the specified time
for performance shall be extended by the period of time equal to the period of the delay
actually so caused.

compensation made by any agent, broker, salesman or finder other than Cornish & Carey and Colliers
International, as a consequence of said party’s actions or dealings with such other agent, broker,
salesman, or finder. Sub-sublandlord agrees to pay a full leasing commission to Colliers
International. Said fee is equal to six percent (6%) of the total base rent for a triple net (NNN)

letter agreement, substantially in the form of Exhibit C attached hereto, has been fully executed
by the parties thereto. Should Colliers International not be paid the commission by the
Sub-sublandlord within such time periods then the Sub-subtenant shall have the right to pay the
said amount of commission owed at that time to the procuring broker (Colliers International) only
and such payments can be deducted from any future rental payments from Sub-subtenant to
Sub-sublandlord.

     IN WITNESS WHEREOF, Sub-sublandlord and Sub-subtenant have executed this Sub-sublease as of
the Execution Date.

Re: Triple Net Sub-Sublease, dated as of June 27, 2006

Ladies/Gentlemen:

     Terayon Communication Systems, Inc., as sub-sublandlord (“Sub-sublandlord”), and
Citrix Systems, Inc., as sub-subtenant (“Sub-subtenant”), have entered into a Triple Net
Sub-Sublease, dated as of June 27, 2006 (the “Sub-sublease”).

     Notwithstanding that the Sub-sublease has by its terms terminated pursuant to Section 4
thereof by reason of the failure of certain conditions precedent specified in Section 4 to occur by
June 30, 2006, the parties hereto reaffirm the effectiveness of the Sub-sublease and now intend to
extend the date by which certain conditions precedent must occur and to make certain other
amendments to the Sub-sublease, as provided in this letter agreement, which shall constitute an
amendment to the Sub-sublease. Unless otherwise defined herein, capitalized terms used in this
agreement have their respective meanings set forth in the Sub-sublease. Therefore, for good and
valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties
hereto hereby agree as follows:

          1. Section 4. The first paragraph in Section 4 of the Sub-sublease is hereby deleted
in its entirety and replaced by the following:

               “4. CONDITIONS PRECEDENT TO EFFECTIVE SUB-SUBLEASE COMMENCEMENT DATE. Notwithstanding the
Sub-sublandlord’s and Sub-subtenant’s full execution of this Sub-sublease, the Sub-sublease Term
shall not commence unless all of the following eight (8) conditions precedent (the “Conditions
Precedent”) have occurred on or before June 23, 2006 (the “Conditions Precedent Satisfaction
Date”). If any of the Conditions Precedent fail to occur by the Conditions Precedent Satisfaction
Date (subject to force majeure as set forth in Subsection 12.3 below), the Targeted Delivery Date
shall be extended one business day for each business day of delay in the occurrence of all the
Conditions Precedent. If any of the Conditions Precedent fail to occur by July 31, 2006, this
Sub-sublease shall terminate, which termination shall render all terms and conditions hereunder
null and void, unless: (1) the Sub-sublandlord and Sub-subtenant mutually agree in writing to
extend such date, or (2) on July 31, 2006, Sub-subtenant waives one or more of the unsatisfied
Conditions Precedent by giving Sub-sublandlord written notice thereof.”

 

 

          2. Subsection 4.3. Subsection 4.3 of the Sub-sublease is hereby deleted in its
entirety and replaced by the following new Subsection 4.3:
