Rental Rate per Rentable Square Foot by the number of rentable square feet of
space in the applicable Premises. Thereafter, the calculation of Annual Base
Rent (and Monthly Installment of Base Rent) reflects an annual increase of 3%.
Accordingly, the Monthly Rental Rate per Rentable Square Foot for Lease Years 2
—5 are only an approximation for reference purposes only.

ARTICLE 1

PREMISES, BUILDING, PROJECT, AND COMMON AREAS

     1.1 Premises, Building, Project and Common Areas.

          1.1.1 The Premises. Landlord hereby leases to Tenant and Tenant hereby leases from
Landlord the premises set forth in Section 2.2 of the Summary, consisting of the Building F
Premises, the Building A Premises, and the Building C Premises (collectively, the “Premises”). The
outline of the Premises is set forth in Exhibit A attached hereto and each floor or floors
of the Premises has or have approximately the number of rentable square feet as set forth in
Section 2.2 of the Summary. The parties hereto agree that the lease of the Premises is
upon and subject to the terms, covenants and conditions (the “TCCs”) herein set forth, and Tenant
covenants as a material part of the consideration for this Lease to keep and perform each and all
of such TCCs by it to be kept and performed and that this Lease is made upon the condition of such
performance. The parties hereto hereby acknowledge that the purpose of Exhibit A is to
show the approximate location of the Premises in the “Buildings,” as that term is defined in
Section 1.1.2, below, only, and such Exhibit is not meant to constitute an agreement,
representation or warranty as to the construction of the Premises, the precise area thereof or the
specific location of the “Common Areas,” as that term is defined in Section 1.1.3, below,
or the elements thereof or of the accessways to the Premises or the “Project,” as that term is
defined in Section 1.1.2, below. Except as specifically set forth in this Lease and in the
Tenant Work Letter attached hereto as Exhibit B (the “Tenant Work Letter”), Landlord shall
not be obligated to provide or pay for any improvement work or services related to the improvement
of the Premises. Tenant acknowledges that Tenant is currently in possession of the Premises
pursuant to that certain lease by and between Malibu Canyon Office Partners, LLC,
predecessor-in-interest to Landlord, and Tenant (formerly known as Ixia Communications, Inc.),
dated November 5, 1999, as amended (the “Existing Lease”), and, therefore, the continued possession
of the Premises by Tenant on and after the date of this Lease shall presumptively establish that
the Premises and the Building were at such time in good and sanitary order, condition and repair,
subject to the completion of “Landlord’s work,” as that term is defined in Section 1.2 of
the Tenant Work Letter. Notwithstanding anything set forth in the Existing Lease to the contrary,
upon the Lease Commencement Date the Existing Lease shall terminate in its entirety and shall be of
no further force or effect (except with respect to those provisions which specifically survive the
expiration or earlier termination of the Existing Lease). Tenant also acknowledges that neither
Landlord nor any agent of Landlord has made any representation or warranty regarding the condition
of the Premises, the Buildings or the Project or with respect to the suitability of any of the
foregoing for the conduct of Tenant’s business, except as specifically set forth in this Lease and
the Tenant Work Letter.

          1.1.2 The Buildings and The Project. The Premises are contained within the buildings
(“Building F”, “Building A” and “Building C”) set forth in Section 2.1 of the
Summary (Building F, Building A and Building C are sometimes individually referred to herein
as “Building” and collectively referred to herein as the “Buildings”). The Buildings are part of
an office project known as “Corporate Center — Calabasas.” The term “Project,” as used in this
Lease, shall mean (i) the Buildings and the Common Areas, (ii) the land (which is improved with
landscaping, parking facilities and other improvements) upon which the Buildings and the

-6-

 

Common Areas are located, (iii) the other office buildings located adjacent to the Buildings and the land
upon which such adjacent office buildings are located, and (iv) at Landlord’s discretion, any
additional real property, areas, land, buildings or other improvements located in the vicinity of
the Project and which are added thereto (collectively, “Additional Property”); provided, however,
(A) the addition of any such Additional Property shall not materially interfere with Tenant’s
access to, and/or use of the Premises or result in an increase in the amount of Direct Expenses
payable by Tenant over the amount of Direct Expenses payable by Tenant immediately prior to the
addition of the Additional Property, and (B) if Landlord, during any Expense Year after the Base
Year, adds any Additional Property to the Project pursuant to the foregoing item (iv), then the
Direct Expenses for the Base Year shall be equitably adjusted (either increased or decreased) by
Landlord to an amount that Landlord reasonably determines that Direct Expenses would have been had
such Additional Property been a part of the Project during the same period of time during the Base
Year as such Additional Property was included in the Project during such subsequent Expense Year.

          1.1.3 Common Areas. Tenant shall have the non-exclusive right to use in common with
other tenants in the Project, and subject to the rules and regulations referred to in Article
5 of this Lease, those portions of the Project which are provided, from time to time, for use
in common by Landlord, Tenant and any other tenants of the Project (such areas, together with such
other portions of the Project designated by Landlord, in its discretion, including certain areas
designated for the exclusive use of certain tenants, or to be shared by Landlord and certain
tenants, are collectively referred to herein as the “Common Areas”). The Common Areas shall
consist of the “Project Common Areas” and the “Building Common Areas.” The term “Project Common
Areas,” as used in this Lease, shall mean the portion of the Project designated as such by
Landlord. The term “Building Common Areas,” as used in this Lease, shall mean the portions of the
Common Areas located within each Building designated as such by Landlord. The manner in which the
Common Areas are maintained and operated shall be at the reasonable discretion of Landlord (but
shall at least be consistent with the manner in which the common areas of the “Comparable
Buildings,” as that term is defined in Section 2.2.2 of this Lease, below, are maintained
and operated) and the use thereof shall be subject to such rules, regulations and restrictions as
Landlord may reasonably make from time to time, provided that such rules, regulations and
restrictions do not unreasonably interfere with the rights granted to Tenant under this Lease and
the permitted use granted under Section 5.1, below. Landlord reserves the right to close
temporarily, make alterations or additions to, or change the location of elements of the Project
and the Common Areas; provided that no such changes shall be permitted which materially reduce
Tenant’s rights or access hereunder, and Landlord shall perform such closures, alterations,
additions or changes in a commercially reasonable manner and, in connection therewith, shall use
commercially reasonable efforts to minimize any material interference with Tenant’s use of and
access to the Premises. Except when and where Tenant’s right of access is specifically excluded in
this Lease, Tenant shall have the right of access to the Premises, the Building, and the Project
parking facility twenty-four (24) hours per day, seven (7) days per
week during the “Lease Term,” as that term is defined in Section 2.1, below.

     1.2 Verification of Rentable and Usable Square Feet of Premises and Buildings. For
purposes of this Lease, “rentable square feet” and “usable square feet” of the Premises shall be
deemed as set forth in Section 2.2 of the Summary and the rentable square feet of the
Buildings shall be deemed as set forth in Section 2.1 of the Summary.

     1.3 Right of First Offer. Landlord hereby grants to the originally named Tenant
herein (“Original Tenant”), and any “Permitted Assignee,” as that term is defined in Section
1.3.6 of this Lease, below, a right of first offer with respect to that certain space located
in Building C and commonly known as Suite 100 (the “First Offer Space”). Notwithstanding the
foregoing, such first offer right of Tenant shall commence only following the expiration or earlier
termination of the existing leases (including renewals) of the First Offer Space, and such right of
first offer shall be subordinate to all rights of tenants under leases of the First Offer Space
existing as of the date hereof, regardless of whether such rights are executed strictly in
accordance with their respective terms or pursuant to lease amendments or new leases (all such
tenants under existing leases of the First Offer Space and other tenants of the Project,
collectively, the “Superior Right Holders”). Tenant’s right of first offer shall be on the terms
and conditions set forth in this Section 1.3.

          1.3.1 Procedure for Offer. Landlord shall notify Tenant (a “First Offer Notice”) from
time to time when the First Offer Space or any portion thereof becomes available for lease to third
parties (other than Superior Right Holders). Pursuant to such First Offer Notice, Landlord shall
offer to lease to Tenant the then available First Offer Space. A First Offer Notice shall describe
the space so offered to Tenant and shall set forth the “First Offer Rent,” as that term is defined
in Section 1.3.3, below, and the other economic terms upon which Landlord is willing to
lease such space to Tenant.

          1.3.2 Procedure for Acceptance. If Tenant wishes to exercise its right of first offer
with respect to the space described in a First Offer Notice, then within seven (7) days of delivery
of such First Offer Notice to Tenant, Tenant shall deliver notice to Landlord irrevocably
exercising Tenant’s right of first offer with respect to the entire space described in such First
Offer Notice and either (i) accepting the First Offer Rent and the other economic terms set forth
in the First Offer Notice (the “Other Economic Terms”), in which case Tenant’s lease of the First
Offer Space shall be at the First Offer Rent and Other Economic Terms, or (ii) rejecting the First
Offer Rent and Other Economic Terms, in which case the First Offer Rent and other economic terms
applicable to Tenant’s lease of the First Offer Space shall be determined pursuant to arbitration
as set forth in Section 2.2.4 of this Lease, below. If Tenant delivers notice to Landlord
irrevocably exercising Tenant’s right of first offer with respect to the entire space described in
such First Offer Notice but fails to accept or reject the First Offer Rent and Other Economic
Terms, then Tenant shall be deemed to have accepted the First Offer Rent and Other Economic Terms.
Notwithstanding anything to the contrary contained herein, Tenant must elect to exercise its right
of first offer, if at all, with respect to all of the space offered by Landlord to Tenant at any
particular time, and Tenant may not elect to lease only a portion thereof. If Tenant
does not exercise its right of first offer with respect to any space described in a First
Offer Notice or if Tenant fails to respond to a First Offer Notice within seven (7) days of
delivery thereof, then Tenant’s right of first offer as set forth in this Section 1.3 shall
terminate as to all of the space described in such First Offer Notice.

          1.3.3 First Offer Space Rent. The annual “Rent,” as that term is defined in Section
4.1 of this Lease, payable by Tenant for the First Offer Space (the “First Offer Rent”) shall be
equal to the “Market Rent,” as that term is defined in Section 2.2.2 of this Lease, for the
First Offer Space, pursuant to transactions consummated within the nine (9)-month period

-8-

 

preceding the “First Offer Commencement Date,” as that term is defined in Section 1.3.5 of this
Lease.

          1.3.4 Construction In First Offer Space. Tenant shall accept the First Offer Space in
its then existing “as is” condition; provided, however, the foregoing shall not be interpreted to
mean that Landlord is prevented from providing a tenant improvement allowance to Tenant in
connection with the First Offer Space. The construction of improvements in the First Offer Space
shall comply with the terms of Article 8 of this Lease.

          1.3.5 Amendment to Lease. If Tenant timely exercises Tenant’s right to lease First
Offer Space as set forth herein, then, within thirty (30) days thereafter, Landlord and Tenant
shall execute an amendment to this Lease adding such First Offer Space to the Premises upon the
terms and conditions as set forth in the First Offer Notice therefor and this Section 1.3;
provided, however, if the First Offer Rent has not been determined prior to the date such amendment
is executed by the parties, then the amendment shall reflect the fact that the First Offer Rent
shall be determined pursuant to the process set forth in Section 2.2.4, below. Tenant
shall commence payment of Rent for such First Offer Space, and the term of such First Offer Space
shall commence, upon the date of delivery of such First Offer Space to Tenant (the “First Offer
Commencement Date”) and terminate on the date set forth in the First Offer Notice therefor.

          1.3.6 Termination of Right of First Offer. The rights contained in this Section
1.3 shall be personal to Original Tenant and any Permitted Assignee, and may only be exercised
by Original Tenant or a Permitted Assignee (and not by any other assignee or sublessee of Tenant’s
interest in this Lease) if Original Tenant or a Permitted Assignee occupies at least seventy
percent (70%) of the entire Premises, provided that for the purposes of this Section 1.3.6,
the Original Tenant or Permitted Assignee, as the case may be, shall be deemed to be in occupancy
of any space sublet to any Transferee pursuant to a sublease consented to by Landlord pursuant to
the terms of Article 14 of this Lease. In addition, Landlord hereby acknowledges that
following the proper exercise of Tenant’s right to lease First Offer Space as set forth herein,
Tenant may thereafter sublet the First Offer Space to a subtenant approved by Landlord pursuant to
the terms and conditions of Article 14, below. The right of first offer granted herein
shall terminate as to any space described in a First Offer Notice upon the failure by Tenant to
exercise its right of first offer with respect to such space as offered by Landlord. Tenant shall
not have the right to lease First Offer Space, as provided in this Section 1.3, if, as of
the date of the attempted exercise of any right of first offer by Tenant, or as of the scheduled
date of delivery of such First Offer Space to Tenant, Tenant is in default under this Lease or
Tenant has previously been in default under this Lease more than once. As used in this Lease, the
term “Permitted Assignee” shall mean any Transferee that is an assignee of Tenant’s entire interest
in this Lease pursuant to an assignment consented to by Landlord pursuant to the terms of
Article 14 of this Lease, or which Landlord’s consent was not required pursuant to the
terms of Section 14.8 of this Lease.

     1.4 Right of First Refusal. Landlord hereby grants to Original Tenant and any
Permitted Assignee a one-time right of first refusal (the “First Refusal Right”) with respect to
that certain space commonly known as Suite 100 and located in that certain building (the “26707
Building”) located in the Project and commonly known by the street address of 26707 W.

-9-

 

Agoura Road, Calabasas, California (the “First Refusal Space”). Such First Refusal Right shall be on the terms
and conditions set forth in this Section 1.4.

          1.4.1 Procedure for Lease.

               1.4.1.1 Procedure for Offer. Landlord shall notify Tenant (the “First Refusal
Notice”) from time-to-time when and if Landlord receives a “bona-fide third-party offer” for all or
a portion of the First Refusal Space. Pursuant to such First Refusal Notice, Landlord shall offer
to lease to Tenant the applicable First Refusal Space. The First Refusal Notice shall describe the
First Refusal Space, and the lease term, rent and other fundamental economic terms and conditions,
including the method of measurement of rentable square feet, upon which Landlord proposes to lease
such First Refusal Space pursuant to the bona-fide third-party offer (collectively, the “First
Refusal Rent”). For purposes of this Section 1.4, a “bona-fide third-party offer” shall
mean a counter-offer received by Landlord to lease First Refusal Space from a qualified third
party, unaffiliated with Landlord, which Landlord would otherwise be willing to accept. For
purposes of example only, the following would each constitute a bone-fide third-party offer:

	 	(i)	 	Landlord receives a request for
proposal from a qualified third party. Landlord responds to the
request for proposal with a lease proposal and subsequently
receives a written bona-fide counter proposal from the qualified
third party acceptable to Landlord.
	 
	 	(ii)	 	Landlord receives a written offer
to lease from a qualified third party. Landlord responds to the
offer with a written counter offer and subsequently receives a
bona-fide counter to Landlord’s counter offer from the qualified
third party acceptable to Landlord.

               1.4.1.2 Procedure for Acceptance. If Tenant wishes to exercise Tenant’s right of
first refusal with respect to the First Refusal Space described in the First Refusal Notice, then
within seven (7) days of delivery of the First Refusal Notice to Tenant, Tenant shall deliver
notice to Landlord of Tenant’s exercise of its right of first refusal with respect to all of the
First Refusal Space described in the First Refusal Notice at the rent, for the term and upon the
other fundamental economic terms and conditions pursuant to Section 1.4.2, below. If
Tenant does not so notify Landlord within such seven (7) day period of Tenant’s exercise of its first refusal
right, then Landlord shall be free to negotiate and enter into a lease for the First Refusal Space
to anyone whom it desires on whatever terms Landlord desires. To the extent Landlord enters into
any lease of First Refusal Space with any such third party in accordance with the foregoing (“Third
Party Lease”), Tenant’s rights under this Section 1.4 shall be subordinate to the rights of
the tenant under the Third Party Lease with respect to the space leased and encumbered pursuant to
the provisions of the Third Party Lease, all extensions and renewals thereof, all pure expansion
options contained therein which are stated as Landlord delivery obligations within a certain time
frame for a certain amount of space, and all right of first offer expansions contained therein.

-10-

 

          1.4.2 Amendment to Lease. If Tenant timely exercises Tenant’s right of first refusal
to lease First Refusal Space as set forth herein, Landlord and Tenant shall within thirty (30) days
thereafter execute an amendment to this Lease adding such First Refusal Space to the Premises on
the terms and conditions contained in this Lease and this Section 1.4. The term of
Tenant’s lease of any such First Refusal Space shall commence on the date (the “First Refusal
Commencement Date”) upon which Landlord delivers such First Refusal Space to Tenant.

          1.4.3 Termination of First Refusal Right. The rights contained in this Section
1.4 shall be personal to the Original Tenant and any Permitted Assignee (and not any other
assignee or sublessee), and shall be exercisable only so long as the Original Tenant or a Permitted
Assignee occupies at least seventy percent (70%) of the entire Premises, provided that for the
purposes of this Section 1.4.3, the Original Tenant or Permitted Assignee, as the case may
be, shall be deemed to be in occupancy of any space sublet to any Transferee pursuant to a sublease
consented to by Landlord pursuant to the terms of Article 14 of this Lease. In addition,
Landlord hereby acknowledges that following the proper exercise of Tenant’s right to first refusal
as set forth herein, Tenant may thereafter sublet the First Refusal Space to a subtenant approved
by Landlord pursuant to the terms and conditions of Article 14, below. Tenant shall not
have the right to lease any First Refusal Space, as provided in this Section 1.4, if (i) as
of the date Landlord would otherwise be required to provide the First Refusal Notice, Tenant is in
default under this Lease, or (ii) as of the date Landlord would otherwise be required to provide
the First Refusal Notice, Tenant has been in default, after expiration of any applicable notice or
cure periods, more than twice. Notwithstanding anything set forth in this Lease to the contrary,
in the event Landlord sells the 26707 Building separately from the Buildings, then, prior to the
consummation of such sale, Landlord shall record a memorandum of Tenant’s right of first refusal on
title of the 26707 Building.

ARTICLE 2

LEASE TERM; OPTION TERM(S)

     2.1 Initial Lease Term. The TCCs and provisions of this Lease shall be effective as
of the date of this Lease; provided, however, prior to the expiration of the Existing Lease, Tenant
shall continue to lease the Premises pursuant to the terms and provisions of the Existing Lease;
provided further, however, the construction of any and all improvements in the Premises prior to
and after the expiration of the Existing Lease shall be governed the terms and provisions of this
Lease, including without limitation the Tenant Work Letter. The term of this Lease (the
“Lease Term”) shall be as set forth in Section 3.1 of the Summary, shall commence on the
date set forth in Section 3.2 of the Summary (the “Lease Commencement Date”), and shall
terminate on the date set forth in Section 3.3 of the Summary (the “Lease Expiration Date”)
unless this Lease is sooner terminated as hereinafter provided. For purposes of this Lease, the
term “Lease Year” shall mean each consecutive twelve (12) month period during the Lease Term;
provided that the last Lease Year shall end on the Lease Expiration Date. At any time during the
Lease Term, Landlord may deliver to Tenant a notice in the form as set forth in Exhibit C,
attached hereto, as a confirmation only of the information set forth therein, which Tenant shall
execute and return to Landlord within ten (10) days of receipt thereof.

-11-

 

     2.2 Option Terms.

          2.2.1 Option Right. Landlord hereby grants the Original Tenant one (1) option to
extend the Lease Term for the entire Premises by a period of five (5) years ( an “Option Term”).
Such option shall be exercisable only by Notice delivered by Tenant to Landlord as provided below,
provided that, as of the date of delivery of such Notice, Tenant is not in default under this
Lease. Upon the proper exercise of such option to extend, and provided that, as of the end of the
Lease Term, Tenant is not in default under this Lease (beyond any applicable notice and cure
periods), the Lease Term, as it applies to the entire Premises, shall be extended for a period of
five (5) years. The rights contained in this Section 2.2 may only be exercised by the
Original Tenant (and not any assignee, sublessee or other transferee of the Original Tenant’s
interest in this Lease) if Original Tenant is in occupancy of the entire then-existing Premises.

          2.2.2 Option Rent. The Rent payable by Tenant during the Option Term (the “Option
Rent”) shall be equal to the Market Rent as set forth below, and the Base Year shall be adjusted
(with corresponding consideration to be given in determining the Market Rent) to be the calendar
year in which the Option Term commences. For purposes of this Lease, the term “Market Rent” shall
mean rent (including additional rent and considering any “base year” or “expense stop” applicable
thereto, and also considering the fact that Tenant is not required to pay a separate amount for
parking), including all escalations, at which tenants, as of the commencement of the Option Term,
or the First Offer Commencement Date, as applicable, are, pursuant to new or renewal transactions
completed within the eighteen (18) months prior to the first day of the Option Term (or, if
applicable, nine (9) months prior to the First Offer Commencement Date), leasing non-sublease,
non-encumbered space, comparable in size, location and quality to the Premises or First Offer
Space, as applicable, for a “Comparable Term,” as that term is defined in this Section
2.2.2 (the “Comparable Deals”), which comparable space is located in the “Comparable
Buildings,” as that term is defined in this Section 2.2.2, giving appropriate consideration
to the annual rental rates per rentable square foot (adjusting the base rent component of such rate
to reflect a net value after accounting for whether or not janitorial and electricity expenses are
directly paid by the tenant such as Tenant’s direct janitorial and electricity payments provided
for in Section 6.1 of this Lease), the standard of measurement by which the rentable square
footage is measured, the ratio of rentable square feet to usable square feet, and taking into
consideration only, and granting only, the following concessions (provided that the rent payable in Comparable Deals
in which the terms of such Comparable Deals are determined by use of a discounted fair market rate
formula shall be equitably increased in order that such Comparable Deals will not reflect a
discounted rate) (collectively, the “Rent Concessions”): (a) rental abatement concessions, if any,
being granted such tenants in connection with such comparable spaces; (b) tenant improvements or
allowances provided or to be provided for such comparable space, taking into account the value of
the existing improvements in the Premises or First Offer Space, as applicable, such value to be
based upon the age, quality and layout of the improvements and the extent to which the same could
be utilized by general office users as contrasted with this specific Tenant, (c) real estate
brokerage commissions, if applicable, paid by the landlord in connection with such comparable
space, and (d) all other reasonable monetary concessions, if any, being granted such tenants in
connection with such comparable space; provided, however, that in calculating the Market Rent, no
consideration shall be given to any period of rental abatement, if any, granted to tenants in
comparable transactions in connection with the design, permitting and construction of tenant

-12-

 

improvements in such comparable spaces. The term “Comparable Term” shall refer to the length of
the lease term, without consideration of options to extend such term, for the space in question.
In addition, the determination of the Market Rent shall include a determination as to whether, and
if so to what extent, Tenant must provide Landlord with financial security, such as a letter of
credit, for Tenant’s rent obligations during any Option Term or in connection with Tenant’s lease
of the First Offer Space; provided, however, in no event shall Landlord require additional security
from Tenant in an amount that exceeds Landlord’s actual out-of-pockets costs (e.g., leasing
commissions and/or improvement allowances) in connection with Tenant ‘s lease of the Premises
during the Option Term or Tenant’s lease of the First Offer Space, as applicable; provided further,
however, if Tenant’s “Net Worth,” as that term is defined in Section 14.8 of this Lease,
below, as of the commencement of the Option Term or the First Offer Commencement Date, as
applicable, is equal to or greater than the Net Worth of the Original Tenant on the date of this
Lease, then Tenant shall not be required to provide Landlord with any additional financial security
for Tenant’s rent obligations during the Option Term or Tenant’s lease of the First Offer Space, as
applicable. Such determination shall be made by reviewing the extent of financial security then
generally being imposed in Comparable Deals upon tenants of comparable Net Worth to the then
existing Net Worth of Tenant (with appropriate adjustments to account for differences in the
then-existing financial condition of Tenant and such other tenants) If in determining the Market
Rent in connection with the Option Term or in connection with Tenant’s lease of the First Offer
Space, Tenant is entitled to a tenant improvement or comparable allowance for the improvement of
the Premises or First Offer Space, as applicable (the “TI Allowance”), Landlord may, at Landlord’s
sole option, elect any or a portion of the following: (A) to grant some or all of the TI Allowance
to Tenant in the form as described above (i.e., as an improvement allowance), and/or (B) to reduce
the rental rate component of the Market Rent to be an effective rental rate which takes into
consideration the fact that Tenant will not receive the total dollar value of such excess TI
Allowance (in which case the TI Allowance evidenced in the effective rental rate shall not be
granted to Tenant). The term “Comparable Buildings” shall mean the Buildings, the other building
in the Project, and the other first-class office buildings which are comparable to the Buildings in
terms of age (based upon the date of completion of construction or major renovation as to the
building containing the portion of the Premises in question), quality of construction, level
of services and amenities, size and appearance, and are located within the area bounded by De Soto
Avenue as the Eastern border, Highway 23 as the Western border, a line parallel to, and one-half
mile South of, Highway 101 as the Southern border, and a line parallel to, and one-half mile North
of, Highway 101 as the Northern border (the (“Comparable Area”).

          2.2.3 Exercise of Option. The option contained in this Section 2.2 shall be
exercised by Tenant, if at all, only in the manner set forth in this Section 2.2.3. Tenant
shall deliver notice (the “Exercise Notice”) to Landlord not more than eighteen (18) months nor
less than twelve (12) months prior to the expiration of the Lease Term, stating that Tenant is
irrevocably exercising its option.

          2.2.4 Determination of Market Rent. In the event Tenant timely and appropriately
exercises an option to extend the Lease Term, or if Tenant irrevocably exercises its right of first
offer with respect to the entire space described in a First Offer Notice and rejects the First
Offer Rent and other economic terms set forth in the First Offer Notice, then Landlord shall (i)
with respect to Market Rent for the Premises during the Option Term, notify Tenant of

-13-

 

Landlord’s determination of the Market Rent on or before the Lease Expiration Date, and (ii) with respect to
Tenant’s lease of First Offer Space, notify Tenant of Landlord determination of the Market Rent
applicable to the First Offer Space (which may or may not be the same as the First Offer Rent set
forth in the First Offer Notice) on or before the First Offer Commencement Date. If Tenant, on or
before the date which is thirty (30) days following the date upon which Tenant receives Landlord’s
determination of the applicable Market Rent pursuant to the immediately preceding sentence, in good
faith objects to Landlord’s determination of the Market Rent, then Landlord and Tenant shall
attempt to agree upon the Market Rent using their best good-faith efforts. If Landlord and Tenant
fail to reach agreement within thirty (30) days following Tenant’s objection to the Market Rent
(the “Outside Agreement Date”), then each party shall make a separate determination of the Market
Rent within five (5) days, and such determinations shall be submitted to arbitration in accordance
with Sections 2.2.4.1 through 2.2.4.7, below.

               2.2.4.1 Landlord and Tenant shall each appoint one arbitrator who shall by profession be a
real estate broker, appraiser or attorney who shall have been active over the five (5) year period
ending on the date of such appointment in the leasing (or appraisal, as the case may be) of
first-class office properties in the Comparable Area. The determination of the arbitrators shall
be limited solely to the issue of whether Landlord’s or Tenant’s submitted Market Rent, is the
closest to the actual Market Rent as determined by the arbitrators, taking into account the
requirements of Section 2.2.2 of this Lease. Each such arbitrator shall be appointed
within fifteen (15) days after the applicable Outside Agreement Date. Landlord and Tenant may
consult with their selected arbitrators prior to appointment and may select an arbitrator who is
favorable to their respective positions. The arbitrators so selected by Landlord and Tenant shall
be deemed (“Advocate Arbitrators”).

               2.2.4.2 The two Advocate Arbitrators so appointed shall be specifically required pursuant to
an engagement letter within ten (10) days of the date of the appointment of
the last appointed Advocate Arbitrator agree upon and appoint a third arbitrator (“Neutral
Arbitrator”) who shall be qualified under the same criteria set forth hereinabove for qualification
of the two Advocate Arbitrators except that neither the Landlord or Tenant or either party’s
Advocate Arbitrator may, directly or indirectly, consult with the Neutral Arbitrator prior to
subsequent to his or her appearance. The Neutral Arbitrator shall be retained via an engagement
letter jointly prepared by Landlord’s counsel and Tenant’s counsel.

               2.2.4.3 The three arbitrators shall within thirty (30) days of the appointment of the Neutral
Arbitrator reach a decision as to Market Rent and determine whether the Landlord’s or Tenant’s
determination of Market Rent as submitted pursuant to Section 2.2.4 of this Lease is
closest to Market Rent as determined by the arbitrators and simultaneously publish a ruling
(“Award”) indicating whether Landlord’s or Tenant’s submitted Market Rent is closest to the Market
Rent as determined by the arbitrators. Following notification of the Award, the Landlord’s or
Tenant’s submitted Market Rent determination, whichever is selected by the arbitrators as being
closest to Market rent shall become the then applicable Market Rent.

               2.2.4.4 The Award issued by the majority of the three arbitrators shall be binding upon
Landlord and Tenant.

-14-

 

               2.2.4.5 If either Landlord or Tenant fail to appoint an Advocate Arbitrator within fifteen
(15) days after the applicable Outside Agreement Date, either party may petition the presiding
judge of the Superior Court of Los Angeles County to appoint such Advocate Arbitrator subject to
the criteria in Section 2.2.4.1 of this Lease, or if he or she refuses to act, either party
may petition any judge having jurisdiction over the parties to appoint such Advocate Arbitrator.

               2.2.4.6 If the two Advocate Arbitrators fail to agree upon and appoint the Neutral Arbitrator,
then either party may petition the presiding judge of the Superior Court of Los Angeles County to
appoint the Neutral Arbitrator, subject to criteria in Section 2.2.4.1 of this Lease, or if
he or she refuses to act, either party may petition any judge having jurisdiction over the parties
to appoint such arbitrator.

               2.2.4.7 The cost of arbitration shall be paid by Landlord and Tenant equally.

               2.2.4.8 In the event that the Market Rent shall not have been determined pursuant to the terms
hereof prior to the commencement of the Option Term, or prior to the First Offer Commencement Date,
as applicable, then Tenant shall be required to pay the Market Rent initially provided by Landlord
to Tenant, and upon the final determination of the Market Rent, the payments made by Tenant shall
be reconciled with the actual amounts of Market Rent due, and the appropriate party shall make any
corresponding payment to the other party.

ARTICLE 3

BASE RENT; BASE RENT ABATEMENT

     3.1 Base Rent. Tenant shall pay, without prior notice or demand, to Landlord or
Landlord’s agent at the management office of the Project, or, at Landlord’s option, at such other
place as Landlord may from time to time designate in writing, by a check for currency which, at the
time of payment, is legal tender for private or public debts in the United States of America, base
rent (“Base Rent”) as set forth in Section 4 of the Summary, payable in equal monthly
installments as set forth in Section 4 of the Summary in advance on or before the first day
of each and every calendar month during the Lease Term, without any setoff or deduction whatsoever,
except as expressly permitted in this Lease. If any Rent payment date (including the Lease
Commencement Date) falls on a day of the month other than the first day of such month or if any
payment of Rent is for a period which is shorter than one month, the Rent for any fractional month
shall be prorated on a daily basis for the period from the date such payment is due to the end of
such calendar month or to the end of the Lease Term at a rate per day which is equal to 1/365 of
the applicable annual Rent. All other payments or adjustments required to be made under the TCCs
of this Lease that require proration on a time basis shall be prorated on the same basis.

     3.2 Base Rent Abatement. Notwithstanding the terms of Section 3.1, above,
provided that Tenant is not in default of this Lease or the Existing Lease, after expiration of any
applicable notice and cure periods expressly set forth in this Lease or the Existing Lease, as
applicable, then commencing on October 1, 2007, Landlord shall apply an amount equal to Two

-15-

 

Hundred Ninety-Two Thousand Seven Hundred Six and 52/100 Dollars ($292,706.52) (the “Rent Abatement
Amount”) against Tenant’s obligation to pay Base Rent otherwise attributable to the Premises under
the Existing Lease until such Rent Abatement Amount has been fully applied.

ARTICLE 4

ADDITIONAL RENT

     4.1 General Terms. In addition to paying the Base Rent specified in Article 3
of this Lease, Tenant shall pay “Tenant’s Share” of the annual “Direct Expenses,” as those terms
are defined in Sections 4.2.6 and 4.2.2, respectively, of this Lease, which are in excess
of the amount of Direct Expenses applicable to the “Base Year,” as that term is defined in
Section 4.2.1, below; provided, however, that in no event shall any decrease in Direct
Expenses for any Expense Year below Direct Expenses for the Base Year entitle Tenant to any
decrease in Base Rent or any credit against sums due under this Lease; provided further, however,
with respect to that portion of Direct Expenses which consist of “Facilities Expenses,” as that
term is defined in Section 4.8 of this Lease, below, Tenant shall pay “Tenant’s Facilities
Share,” as that term is defined in Section 4.9 of this Lease, below, of such Facilities
Expenses. Such payments by Tenant, together with any and all other amounts payable by Tenant to
Landlord pursuant to the TCCs of this Lease, are hereinafter collectively referred to as the
“Additional Rent,” and the Base Rent and the Additional Rent are herein collectively referred to as
“Rent.” All amounts due under this Article 4 as Additional Rent shall be payable for the
same periods and in the same manner as the Base Rent; provided, however, the parties hereby
acknowledge that the first monthly installment of Tenant’s Share of any “Estimated Excess,” as that
term is set forth in, and pursuant to the terms and conditions of, Section 4.4.2 of this
Lease, shall first be due and payable for the calendar month occurring immediately following the
expiration of the Base Year. Without limitation on other obligations of Tenant which survive the
expiration of the Lease Term, the obligations of Tenant to pay the Additional Rent provided for in
this Article 4 shall survive the expiration of the Lease Term.

     4.2 Definitions of Key Terms Relating to Additional Rent. As used in this Article
4, the following terms shall have the meanings hereinafter set forth:

          4.2.1 “Base Year” shall mean the period set forth in Section 5 of the Summary.

          4.2.2 “Direct Expenses” shall mean “Operating Expenses,” “Tax Expenses,” and “Facilities
Expenses.”

          4.2.3 “Expense Year” shall mean each calendar year in which any portion of the Lease Term
falls, through and including the calendar year in which the Lease Term expires, provided that
Landlord, upon notice to Tenant, may change the Expense Year from time to time to any other twelve
(12) consecutive month period, and, in the event of any such change, Tenant’s Share of Direct
Expenses shall be equitably adjusted for any Expense Year involved in any such change.

-16-

 

          4.2.4 “Operating Expenses” shall mean all expenses, costs and amounts of every kind and nature
which Landlord pays or accrues during any Expense Year because of or in connection with the
ownership, management, maintenance, security, repair, replacement, restoration or operation of the
Project, or any portion thereof. Without limiting the generality of the foregoing, Operating
Expenses shall specifically include any and all of the following: (i) the cost of supplying all

including taxes levied thereon, of all persons (other than persons generally considered to be
higher in rank than the position of Project manager) engaged in the operation, maintenance and

Project; (x) operation, repair, maintenance and replacement of all systems and equipment and

connection with the Project (A) which are reasonably intended to effect economies in the operation
or maintenance of the Project, or any portion thereof, (B) that are required to comply with present
or anticipated conservation programs, (C) which are replacements or modifications of nonstructural
items located in the Common Areas required to keep the Common Areas in good order or condition, or
(D) that are required under any governmental law or regulation by a federal, state or local
governmental agency, except for capital repairs, replacements or other improvements to remedy a

required to be remedied pursuant to then-current governmental laws or regulations in their form
existing as of the Lease Commencement Date and pursuant to the then-current interpretation of such
governmental laws or regulations by the applicable governmental authority as of the Lease
Commencement Date; provided, however, that any capital expenditure shall be amortized with interest
over its useful life as Landlord shall reasonably determine; (xiv) costs, fees, charges or
assessments imposed by, or resulting from any mandate imposed on Landlord by, any federal, state or
local government

-17-

 

for fire and police protection, trash removal, community services, or other
services which do not constitute “Tax Expenses” as that term is defined in Section 4.2.5,
below; and (xv) payments under any easement, license, operating agreement, declaration, restrictive
covenant, or instrument pertaining to the sharing of costs by the Buildings. Notwithstanding the
foregoing, for purposes of this Lease, Operating Expenses shall not, however, include:

               (a) costs, including marketing costs, legal fees, space planners’ fees, advertising and
promotional expenses, and brokerage fees incurred in connection with the original construction or
development, or original or future leasing of the Project, and costs, including permit, license and
inspection costs, incurred with respect to the installation of tenant improvements made for new

Project or parking facilities);

               (b) except as set forth in items (xii), (xiii), and (xiv) above, depreciation, interest and
principal payments on mortgages and other debt costs, if any, penalties and interest, costs of

               (e) costs associated with the operation of the business of the partnership or entity which
constitutes the Landlord, as the same are distinguished from the costs of operation of the Project
(which shall specifically include, but not be limited to, accounting costs associated with the
operation of the Project). Costs associated with the operation of the business of the partnership
or entity which constitutes the Landlord include costs of partnership accounting and legal matters,
costs of defending any lawsuits with any mortgagee (except as the actions of the Tenant may be in
issue), costs of selling, syndicating, financing, mortgaging or hypothecating any of the Landlord’s
interest in the Project, and costs incurred in connection with any disputes between Landlord and
its employees, between Landlord and Project management, or between Landlord and other tenants or

               (f) the wages and benefits of any employee who does not devote substantially all of his or her
employed time to the Project unless such wages and benefits are prorated to reflect time spent on
operating and managing the Project vis-a-vis time spent on matters unrelated to operating and
managing the Project; provided, that in no event shall Operating Expenses for purposes of this
Lease include wages and/or benefits attributable to personnel above the level of Project manager;

               (g) amount paid as ground rental for the Project by the Landlord;

-18-

 

               (h) overhead and profit increment paid to the Landlord or to subsidiaries or affiliates of the
Landlord for services in the Project to the extent the same exceeds the costs of such services
rendered by qualified, first-class unaffiliated third parties on a competitive basis;

               (i) any compensation paid to clerks, attendants or other persons in commercial concessions
operated by the Landlord, provided that any compensation paid to any concierge at the Project shall
be includable as an Operating Expense;

               (j) rentals and other related expenses incurred in leasing air conditioning systems, elevators
or other equipment which if purchased the cost of which would be excluded from Operating Expenses
as a capital cost, except equipment not affixed to the Project which is used in providing
janitorial or similar services and, further excepting from this exclusion such equipment rented or
leased to remedy or ameliorate an emergency condition in the Project ;

               (k) all items and services for which Tenant or any other tenant in the Project reimburses
Landlord or which Landlord provides selectively to one or more tenants (other than Tenant) without
reimbursement;

               (l) costs, other than those incurred in ordinary maintenance and repair, for sculpture,
paintings, fountains or other objects of art;

               (m) any costs expressly excluded from Operating Expenses elsewhere in this Lease;

               (n) rent for any office space occupied by Project management personnel to the extent the size
or rental rate of such office space exceeds the size or fair market rental value of office space
occupied by management personnel of the Comparable Buildings in the vicinity of the Building, with
adjustment where appropriate for the size of the applicable project;

               (o) costs to the extent arising from the gross negligence or willful misconduct of Landlord or
its agents, employees, vendors, contractors, or providers of materials or services;

               (p) costs incurred to comply with laws relating to the removal of hazardous material (as
defined under applicable law) which was in existence in the Building or on the Project prior to the
Lease Commencement Date, and was of such a nature that a federal, State or municipal governmental
authority, if it had then had knowledge of the presence of such hazardous material, in the state,
and under the conditions that it then existed in the Building or on the Project, would have then
required the removal of such hazardous material or other remedial or containment action with
respect thereto; and costs incurred to remove, remedy, contain, or treat hazardous material, which
hazardous material is brought into the Building or onto the Project after the date hereof by
Landlord or any other tenant of the Project and is of such a nature, at that time, that a federal,
State or municipal governmental authority, if it had then had knowledge of the presence of such
hazardous material, in the state, and under the conditions, that

-19-

 

it then exists in the Building or on the Project, would have then required the removal of such hazardous material or other remedial
or containment action with respect thereto;

               (q) costs arising from Landlord’s charitable or political contributions;

               (r) any gift provided to any entity whatsoever, including, but not limited to, Tenant, other
tenants, employees, vendors, contractors, prospective tenants and agents;

               (s) any costs covered by any warranty, rebate, guarantee or service contract which are
actually collected by Landlord (which shall not prohibit Landlord from passing through the costs of
any such warranty, rebate, guarantee or service contract if otherwise includable in Operating
Expenses);

               (t) any costs included as a Tax Expense pursuant to Section 4.2.5 below;

               (u) penalties, fines, or fees incurred by Landlord due to Landlord’s violation of any federal,

leased to remedy or ameliorate an emergency condition in the Project;

               (w) costs incurred by Landlord for the repair of damage to the Building, but only to the
extent that Landlord is reimbursed by insurance proceeds, and, except as set forth in items (xii)
and (xiii) above, the costs of all capital repairs, regardless of whether such repairs are covered
by insurance;

               (x) advertising and promotional expenditures, and costs of signs in or on the Building
identifying the owner of the Building or other tenants’ signs;

               (y) penalties, fines, or fees incurred by Landlord in connection with Landlord’s failure to
upgrade the Building to comply with disability, life, fire and safety codes, ordinances, statutes,
or other laws in effect prior to the Lease Commencement Date, including, without limitation, the
Americans with Disabilities Act; and

               (z) any entertainment, dining or travel expenses for any purpose.

     If Landlord is not furnishing any particular work or service (the cost of which, if performed
by Landlord, would be included in Operating Expenses) to a tenant who has undertaken to perform
such work or service in lieu of the performance thereof by Landlord, Operating Expenses shall be
deemed to be increased by an amount equal to the additional Operating Expenses which would
reasonably have been incurred during such period by Landlord

-20-

 

if it had at its own expense furnished
such work or service to such tenant. If any Building is not at least ninety-five percent (95%)
occupied during all or a portion of the Base Year or any Expense Year, Landlord shall make an
appropriate adjustment in accordance with sound real estate management and accounting practices to
the variable components of Operating Expenses (i.e., those components which vary based upon
occupancy) for such year to determine the amount of Operating Expenses that would have been
incurred had such Building been ninety-five percent (95%) occupied; and the amount so determined
shall be deemed to have been the amount of Operating Expenses for such year. Operating Expenses
for the Base Year shall not include market-wide cost increases (including utility rate increases)
due to extraordinary circumstances, including, but not limited to, Force Majeure, boycotts,
strikes, conservation surcharges, embargoes or shortages, or amortized costs relating to capital
improvements. In no event shall the components of Direct Expenses for any Expense Year related to
Project utility, services, or insurance costs be less than the components of Direct Expenses
related to Project utility, services, or insurance costs in the Base Year. Landlord shall not (1)
make a profit by charging items to Operating Expenses that are otherwise also charged separately to
tenants (including Tenant) of the Project, and (2) subject to Landlord’s right to adjust the
components of Operating Expenses described above in this paragraph, collect Operating Expenses from
Tenant and all other tenants in the Project in an amount in excess of what Landlord incurs for the
items included in Operating Expenses.

          4.2.5 Taxes.

               4.2.5.1 “Tax Expenses” shall mean all federal, state, county, or local governmental or
municipal taxes, fees, charges or other impositions of every kind and nature, whether general,
special, ordinary or extraordinary, (including, without limitation, real estate taxes, general and
special assessments, transit taxes, leasehold taxes or taxes based upon the receipt of rent,
including gross receipts or sales taxes applicable to the receipt of rent, unless required to be
paid by Tenant, personal property taxes imposed upon the fixtures, machinery, equipment, apparatus,
systems and equipment, appurtenances, furniture and other personal property used in connection with
the Project, or any portion thereof), which shall be paid or accrued during any Expense Year
(without regard to any different fiscal year used by such governmental or municipal authority)
because of or in connection with the ownership, leasing and operation of the Project, or any
portion thereof.

               4.2.5.2 Tax Expenses shall include, without limitation: (i) Any tax on the rent, right to
rent or other income from the Project, or any portion thereof, or as against the business of
leasing the Project, or any portion thereof; (ii) Any assessment, tax, fee, levy or charge in
addition to, or in substitution, partially or totally, of any assessment, tax, fee, levy or charge
previously included within the definition of real property tax, it being acknowledged by Tenant and
Landlord that Proposition 13 was adopted by the voters of the State of California in the June 1978
election (“Proposition 13”) and that assessments, taxes, fees, levies and charges may be imposed by
governmental agencies for such services as fire protection, street, sidewalk and road maintenance,
refuse removal and for other governmental services formerly provided without charge to property
owners or occupants, and, in further recognition of the decrease in the level and quality of
governmental services and amenities as a result of Proposition 13, Tax Expenses shall also include
any governmental or private assessments or the Project’s contribution towards a governmental or
private cost-sharing agreement for the purpose of augmenting or

-21-

 

improving the quality of services
and amenities normally provided by governmental agencies; (iii) Any assessment, tax, fee, levy, or
charge allocable to or measured by the area of the Premises or the Rent payable hereunder,
including, without limitation, any business or gross income tax or excise tax with respect to the
receipt of such rent, or upon or with respect to the possession, leasing, operating, management,
maintenance, alteration, repair, use or occupancy by Tenant of the Premises, or any portion
thereof; and (iv) Any assessment, tax, fee, levy or charge, upon this transaction or any document
to which Tenant is a party, creating or transferring an interest or an estate in the Premises. All
assessments which can be paid by Landlord in installments, shall be paid by Landlord in the maximum
number of installments permitted by law (except to the extent inconsistent with the general
practice of landlords of the Comparable Buildings) and shall be included as Tax Expenses in the
year in which the installment is actually paid.

               4.2.5.3 Any costs and expenses (including, without limitation, reasonable attorneys’ fees)
incurred in attempting to protest, reduce or minimize Tax Expenses shall be included in Tax
Expenses in the Expense Year such expenses are paid. Except as set forth in Section
4.2.5.4, below, refunds of Tax Expenses shall be credited against Tax Expenses and refunded to
Tenant regardless of when received, based on the Expense Year to which the refund is applicable,
provided that in no event shall the amount to be refunded to Tenant for any such
Expense Year exceed the total amount paid by Tenant as Additional Rent under this Article
4 for such Expense Year. If Tax Expenses for any period during the Lease Term or any extension
thereof are increased after payment thereof for any reason, including, without limitation, error or
reassessment by applicable governmental or municipal authorities, Tenant shall pay Landlord upon
demand Tenant’s Share of any such increased Tax Expenses included by Landlord as Building Tax
Expenses pursuant to the TCCs of this Lease. Notwithstanding anything to the contrary contained in
this Section 4.2.5, there shall be excluded from Tax Expenses (i) all excess profits taxes,
franchise taxes, gift taxes, capital stock taxes, inheritance and succession taxes, estate taxes,
federal and state income taxes (including such income taxes on income from the Project), and other
taxes to the extent applicable to Landlord’s general or net income (as opposed to rents, receipts
or income attributable to operations at the Project), (ii) any items included as Operating
Expenses, (iii) any items paid by Tenant under Section 4.5 of this Lease, and (iv) tax
penalties incurred as a result of Landlord’s failure to make payments and/or to file any tax or
informational returns when due. If the property tax assessment for the Project (or any portion
thereof) (or Tax Expenses) for the Base Year or any Expense Year does not reflect an assessment (or
Tax Expenses) for a one hundred percent (100%) leased, completed and occupied project (such that
existing or future leasing, tenant improvements and/or occupancy may result in an increased
assessment and/or increased Tax Expenses), Tax Expenses shall be adjusted, on a basis consistent
with sound real estate accounting principles, to reflect an assessment for (and Tax Expenses for) a
one hundred percent (100%) leased, completed and occupied project.

               4.2.5.4 Notwithstanding anything to the contrary set forth in this Lease, the amount of Tax
Expenses for the Base Year and any Expense Year shall be calculated without taking into account any
decreases in real estate taxes obtained in connection with Proposition 8, and, therefore, the Tax
Expenses in the Base Year and/or an Expense Year may be greater than those actually incurred by
Landlord, but shall, nonetheless, be the Tax Expenses due under this Lease; provided that (i) any
costs and expenses incurred by Landlord in securing any Proposition 8 reduction shall not be
included in Direct Expenses for purposes of this Lease, and

-22-

 

(ii) tax refunds under Proposition 8
shall not be deducted from Tax Expenses, but rather shall be the sole property of Landlord.
Landlord and Tenant acknowledge that this Section 4.2.5.4 is not intended to in any way
affect (A) the inclusion in Tax Expenses of the statutory two percent (2.0%) annual increase in Tax
Expenses (as such statutory increase may be modified by subsequent legislation), or (B) the
inclusion or exclusion of Tax Expenses pursuant to the terms of Proposition 13, which shall be
governed pursuant to the terms of Sections 4.2.5.1 through 4.2.5.3, above and Section
4.6, below. Notwithstanding the foregoing, upon a “Reassessment,” as that term is defined in
Section 4.6 below, occurring after the Base Year, the component of Tax Expenses for the
Base Year which is attributable to the assessed value of the Project under Proposition 13 prior to
the Reassessment (without taking into account any Proposition 8 reductions) shall be reduced, if at
all, for the purposes of comparison to all subsequent Expense Years (commencing with the Expense
Year in which the Reassessment takes place) to an amount equal to the real estate taxes based upon
such Reassessment.

          4.2.6 “Tenant’s Share” shall mean (i) with respect to the Building F Premises, the percentage
set forth in Section 6.1 of the Summary, (ii) with respect to the Building A Premises, the
percentage set forth in Section 6.2 of the Summary, and (iii) with respect to the Building
C Premises, the percentage set forth in Section 6.3 of the Summary.

     4.3 Allocation of Direct Expenses.

          4.3.1 Method of Allocation. The parties acknowledge that the Buildings are part of a
multi-building project and that certain costs and expenses incurred in connection with the Project
(i.e., the Direct Expenses which are not solely attributable to a specific building of the Project)
should be shared between all of the tenants of Project. Accordingly, as set forth in Section
4.2 above, Direct Expenses (which consists of Operating Expenses and Tax Expenses) are
determined annually for each Building, as well as for the Project as a whole. Thereafter, a
portion of the Direct Expenses attributable to the Project as a whole, and not solely attributable
to a specific building, which portion shall be determined by Landlord on an equitable basis based
on the respective rentable areas of the buildings in the Project, shall be allocated to each
Building (as opposed to any other building in the Project) and such portion shall be the Direct
Expenses for such Building for purposes of this Lease. Such portion of Direct Expenses allocated
to each Building shall include all Direct Expenses attributable solely to such Building and an
equitable portion of the Direct Expenses attributable to the Project as a whole.

          4.3.2 Cost Pools. Landlord shall have the right, from time to time, to equitably
allocate some or all of the Direct Expenses for the Project among different portions or occupants
of the Project (the “Cost Pools”), in Landlord’s discretion. Such Cost Pools may include, but
shall not be limited to, the office space tenants of a building of the Project or of the Project,
and the retail space tenants of a building of the Project or of the Project. The Direct Expenses
within each such Cost Pool shall be allocated and charged to the tenants within such Cost Pool in
an equitable manner.

     4.4 Calculation and Payment of Additional Rent. If for any Expense Year ending or
commencing within the Lease Term, Tenant’s Share of Direct Expenses for such Expense Year exceeds
Tenant’s Share of Direct Expenses applicable to the Base Year, then Tenant shall pay to Landlord,
in the manner set forth in Section 4.4.1, below, and as Additional Rent, an

-23-

 

amount equal to the excess (the “Excess”); provided, however, Landlord hereby agrees that, for any Lease Year
following the Base Year, “Controllable Expenses,” as that term is defined in this Section
4.4, below, shall never be increased to an amount in excess of the amount that such
Controllable Expenses would currently be had they increased, from the initial amount for such
Controllable Expenses set forth in the Base Year, at a compounded rate of five percent (5%) per
Expense Year. For purposes of this Lease, “Controllable Expenses” shall mean (i) the fee
charged by the property manager of the Project, including payment of the property manager’s
administrative and executive salaries, (ii) the amount of rent charged to Operating Expenses as
rent for the Project management office, and (iii) the costs of janitorial service contracts,
security service contracts, landscaping contracts, HVAC maintenance contracts, elevator maintenance
contracts, and life safety maintenance contracts. Furthermore, notwithstanding anything contained
in this paragraph to the contrary, Controllable Expenses shall not include (A) the cost of union
labor, including labor which is not union as of the date of this Lease but which unionizes after
the date of this Lease, (B) market-wide labor-rate increases due to extraordinary circumstances,
including without limitation, boycotts and strikes, (C) costs incurred due to an event of “Force
Majeure,” as that term is defined in Section 29.16 of this Lease, and (D) costs incurred to
comply with “Applicable Laws,” as that term is defined in Article 24 of this Lease.

          4.4.1 Statement of Actual Building Direct Expenses and Payment by Tenant. Landlord
shall give to Tenant following the end of each Expense Year, a statement (the “Statement”) which
shall state in general major categories the Building Direct Expenses incurred or accrued for the
Base Year or such preceding Expense Year, as applicable, and which shall indicate the amount of the
Excess. Landlord shall use commercially reasonable efforts to deliver such Statement to Tenant on
or before May 1 following the end of the Expense Year to which such Statement relates. Upon
receipt of the Statement for each Expense Year commencing or ending during the Lease Term, if an
Excess is present, Tenant shall pay, within thirty (30) days after receipt of the Statement, the
full amount of the Excess for such Expense Year, less the amounts, if any, paid during such Expense
Year as “Estimated Excess,” as that term is defined in Section 4.4.2, below, and if Tenant
paid more as Estimated Excess than the actual Excess, Tenant shall receive a credit in the amount
of Tenant’s overpayment against Rent next due under this Lease. The failure of Landlord to timely
furnish the Statement for any Expense Year shall not prejudice Landlord or Tenant from enforcing
its rights under this Article 4. Even though the Lease Term has expired and Tenant has
vacated the Premises, when the final determination is made of Tenant’s Share of Building Direct
Expenses for the Expense Year in which this Lease terminates, if an Excess is present, Tenant
shall, within thirty (30) days after receipt of the Statement, pay to Landlord such amount, and if
Tenant paid more as Estimated Excess than the actual Excess, Landlord shall, within thirty (30)
days, deliver a check payable to Tenant in the amount of the overpayment. The provisions of this
Section 4.4.1 shall survive the expiration or earlier termination of the Lease Term.
Notwithstanding the immediately preceding sentence, Tenant shall not be responsible for Tenant’s
Share of any Building Direct Expenses attributable to any Expense Year which are first billed to
Tenant more than two (2) calendar years after the Lease Expiration Date, provided that in any event
Tenant shall be responsible for Tenant’s Share of Direct Expenses levied by any governmental
authority or by any public utility companies at any time following the Lease Expiration Date which
are attributable to any Expense Year, and as to which Tenant is otherwise responsible in accordance
with the terms of this Lease.

          4.4.2 Statement of Estimated Building Direct Expenses. In addition, Landlord
shall give Tenant a yearly expense estimate statement (the “Estimate Statement”) which shall set
forth in general major categories Landlord’s reasonable estimate (the “Estimate”) of what the total
amount of Building Direct Expenses for the then-current Expense Year shall be and the estimated
excess (the “Estimated Excess”) as calculated by comparing the Building Direct Expenses for such
Expense Year, which shall be based upon the Estimate, to the amount of Building Direct Expenses for
the Base Year. Landlord shall use commercially reasonable efforts to deliver such Estimate
Statement to Tenant on or before May 1 following the end of the Expense Year to which such Estimate
Statement relates. The failure of Landlord to timely furnish the Estimate Statement for any
Expense Year shall not preclude Landlord from enforcing its rights to collect any Additional Rent
under this Article 4, nor shall Landlord be prohibited from revising any Estimate Statement
or Estimated Excess theretofore delivered to the extent necessary. Thereafter, Tenant shall pay,
within thirty (30) days after receipt of the Estimate Statement, a fraction of the Estimated Excess
for the then-current Expense Year (reduced by any amounts paid pursuant to the second to last
sentence of this Section 4.4.2). Such fraction shall have as its numerator the number of
months which have elapsed in such current Expense Year, including the month of such payment, and
twelve (12) as its denominator. Until a new Estimate Statement is furnished (which Landlord shall
have the right to deliver to Tenant at any time), Tenant shall pay monthly, with the monthly Base
Rent installments, an amount equal to one-twelfth (1/12) of the total Estimated Excess set forth in
the previous Estimate Statement delivered by Landlord to Tenant. Throughout the Lease Term
Landlord shall maintain books and records with respect to Building Direct Expenses in accordance
with generally accepted real estate accounting and management practices, consistently applied.

     4.5 Taxes and Other Charges for Which Tenant Is Directly Responsible.

          4.5.1 Tenant shall be liable for and shall pay before delinquency (unless Tenant is contesting
the same in good faith and in accordance with applicable laws), taxes levied against Tenant’s
equipment, furniture, fixtures and any other personal property located in or about the Premises.
If any such taxes on Tenant’s equipment, furniture, fixtures and any other personal property are
levied against Landlord or Landlord’s property or if the assessed value of Landlord’s property is
increased by the inclusion therein of a value placed upon such equipment, furniture, fixtures or
any other personal property (and a separate assessment is made therefor, or such amount is
otherwise readily discernable from the assessment) and if Landlord pays the taxes based upon such
increased assessment, which Landlord shall have the right to do regardless of the validity thereof
but only under proper protest if requested by Tenant, Tenant shall, within ten (10) days after
demand repay to Landlord the taxes so levied against Landlord or the proportion of such taxes
resulting from such increase in the assessment, as the case may be.

          4.5.2 If the tenant improvements in the Premises, whether installed and/or paid for by
Landlord or Tenant and whether or not affixed to the real property so as to become a part thereof,
are assessed for real property tax purposes at a valuation higher than the valuation at which
tenant improvements conforming to Landlord’s “building standard” in other space in the Buildings
are assessed, pursuant to a separate assessment, or provided that such increase in taxes is
otherwise readily discernable from the assessment, then the Tax Expenses levied against Landlord or
the property by reason of such excess assessed valuation shall be deemed to be taxes

-25-

 

levied against
personal property of Tenant and shall be governed by the provisions of Section 4.5.1,
above.

          4.5.3 Notwithstanding any contrary provision herein, Tenant shall pay prior to delinquency
(unless Tenant is contesting the same in good faith and in accordance with applicable laws) any (i)
rent tax or sales tax, service tax, transfer tax or value added tax, or any other applicable tax on
the rent or services herein or otherwise respecting this Lease, (ii) taxes assessed upon or with
respect to the possession, leasing, operation, management, maintenance, alteration, repair, use or
occupancy by Tenant of the Premises or any portion of the Project, including the Project parking
facility; or (iii) taxes assessed upon this transaction or any document to which Tenant is a party
creating or transferring an interest or an estate in the Premises.

     4.6 Tenant’s Payment of Certain Tax Expenses. Notwithstanding anything to the
contrary contained in this Lease, in the event that, at any time during the first two (2) Lease
Years, any sale, refinancing, or change in ownership of the Building(s) or Project is consummated
(specifically excluding, however, a change in ownership to a lender resulting from a foreclosure or
a deed-in-lieu of foreclosure), and as a result thereof, and to the extent that in connection
therewith, the Building(s) or Project is reassessed (the “Reassessment”) for real estate tax
purposes by the appropriate governmental authority pursuant to the terms of Proposition 13, then
Landlord shall provide Tenant a one-time credit against Base Rent, to be applied against the next
installment of Base Rent due and owing under this Lease, in an amount equal to One Hundred Fifty
Thousand Dollars ($150,000.00). The terms of this Section 4.6 shall be applicable only to
the first such Reassessment that occurs during the first two (2) Lease Years and shall not be
applicable to any subsequent Reassessment.

     4.7 Landlord’s Books and Records. Within one hundred eighty (180) days after receipt
of a Statement by Tenant (the “Review Period”), if Tenant disputes the amount set forth in the
Statement, Tenant’s employees or an independent certified public accountant (which accountant is a
member of a nationally or regionally recognized accounting firm and is not paid on a contingent fee
basis), designated by Tenant, may, after reasonable notice to Landlord and at reasonable times,
inspect Landlord’s records at Landlord’s offices, provided that Tenant is not then in default after
expiration of all applicable cure periods of any obligation under this Lease (including, but not
limited to, the payment of the amount in dispute). In connection with such inspection, Tenant and
Tenant’s agents (including Tenant’s accountant) must agree in advance to follow Landlord’s
reasonable rules and procedures regarding inspections of Landlord’s records, and shall execute a
commercially reasonable confidentiality agreement regarding such inspection. Tenant’s failure to
dispute the amounts set forth in any Statement within the Review Period shall constitute a waiver
of Tenant’s right or ability to dispute the amounts set forth in such Statement. If after such
inspection, but within thirty (30) days after the Review Period, Tenant notifies Landlord in
writing that Tenant still disputes such amounts, a certification as to the proper amount shall be
made, at Tenant’s expense, by an independent certified public accountant selected by Landlord and
subject to Tenant’s reasonable approval and who is a member of a nationally or regionally
recognized accounting firm, which certification shall be binding upon Landlord and Tenant.
Landlord shall cooperate in good faith with Tenant and the accountant to show Tenant and the
accountant the information upon which the certification is to be based. However, if such
certification by the accountant proves that the Direct Expenses set

-26-

 

forth in the Statement were
overstated by more than four percent (4%), then the cost of the accountant and the cost of such
certification shall be paid for by Landlord. Promptly following the parties receipt of such
certification, the parties shall make such appropriate payments or reimbursements, as the case may
be, to each other, as are determined to be owing pursuant to such certification. Tenant hereby
acknowledges that Tenant’s sole right to inspect Landlord’s books and records and to contest the
amount of Direct Expenses payable by Tenant shall be as set forth in this Section 4.7, and
Tenant hereby waives any and all other rights pursuant to applicable law to inspect such books and
records and/or to contest the amount of Direct Expenses payable by Tenant.

     4.8 “Facilities Expenses” shall mean all Operating Expenses and Tax Expenses allocable to any
and all Common Area Facilities.

     4.9 “Tenant’s Facilities Share” shall mean a percentage, which may be expressed as a fraction,
the numerator of which rentable square feet of the Premises and the denominator shall be the total
rentable square footage occupied by tenants of the Project who also pay their respective share of
Facilities Expenses (i.e., unoccupied space in the Project and space occupied by tenant that do not
pay their share of Facilities Expenses shall be excluded).

ARTICLE 5

USE OF PREMISES

     5.1 Permitted Use. Tenant shall use the Premises solely for the Permitted Use set
forth in Section 7 of the Summary and Tenant shall not use or permit the Premises or the
Project to be used for any other purpose or purposes whatsoever without the prior written consent
of Landlord, which may be withheld in Landlord’s sole discretion.

     5.2 Prohibited Uses. The uses prohibited under this Lease shall include, without
limitation, use of the Premises or a portion thereof for (i) offices of any agency or bureau of the
United States or any state or political subdivision thereof (provided, however, that to the extent
Landlord permits an office of any agency or bureau of the United States or any state or political
subdivision thereof to be conducted at the Project, then Tenant shall be permitted to conduct such
uses in a comparable manner and to a comparable extent); (ii) offices or agencies of any foreign
governmental or political subdivision thereof; (iii) offices of any health care professionals or
service organization; (iv) schools or other training facilities which are not ancillary to
corporate, executive or professional office use; (v) retail or restaurant uses; or (vi)
communications firms such as radio and/or television stations. Tenant shall not allow occupancy
density of use of the Premises which is greater than the average density of the other tenants of
the buildings in the Project. Tenant further covenants and agrees that Tenant shall not use, or
suffer or permit any person or persons to use, the Premises or any part thereof for any use or
purpose contrary to the provisions of the Rules and Regulations set forth in Exhibit D,
attached hereto, or in violation of the laws of the United States of America, the State of
California, or the ordinances, regulations or requirements of the local municipal or county
governing body or other lawful authorities having jurisdiction over the Project) including, without
limitation, any such laws, ordinances, regulations or requirements relating to hazardous materials
or substances, as those terms are defined by applicable laws now or hereafter in effect; provided,
however, Landlord shall not

-27-

 

enforce, change or modify the Rules and Regulations in a discriminatory
manner and Landlord agrees that the Rules and Regulations shall not be unreasonably modified or
enforced in a manner which will unreasonably interfere with the normal and customary conduct of
Tenant’s business. Tenant shall not do or permit anything to be done in or about the Premises
which will in any way obstruct or materially interfere with the rights of other tenants or
occupants of the Buildings, or injure or annoy them or use or allow the Premises to be used for any
improper, unlawful or objectionable purpose, nor shall Tenant cause, maintain or permit any
nuisance in, on or about the Premises. Tenant shall comply with all recorded covenants,
conditions, and restrictions now or hereafter affecting the Project.

     5.3 CC&Rs. Tenant shall comply with all recorded covenants, conditions, and
restrictions currently affecting the Project, to the extent Landlord provides a copy of such
recorded covenants, conditions, and restrictions to Tenant. Additionally, Tenant acknowledges that
the Project may be subject to any future covenants, conditions, and restrictions (the “CC&Rs”)
which Landlord, in Landlord’s discretion, deems reasonably necessary or desirable, and Tenant
agrees that this Lease shall be subject and subordinate to such CC&Rs, provided that (i) Landlord
provides a copy of such CC&Rs to Tenant, and (ii) such CC&Rs do not increase Tenant’s obligations,
or decrease Tenant’s rights under the terms of this Lease.

ARTICLE 6

SERVICES AND UTILITIES

     6.1 Standard Tenant Services. Landlord shall maintain and operate the Buildings in a
manner consistent with the Comparable Buildings, and shall keep the Building Structure and Building
Systems in condition and repair consistent with the Comparable Buildings. Landlord hereby
acknowledges that Tenant has upgraded the electrical service supporting portions of the Premises
and that Tenant shall have the right to use such upgraded electrical service to its full capacity.
In addition Tenant may, with Landlord’s prior consent and in accordance with the TCCs of
Article 8 of the Lease, below, perform additional upgrades to the electrical services
supporting the Premises.

          Notwithstanding the foregoing, Tenant shall pay for all utilities (including without
limitation, electricity, gas, sewer and water) attributable to its use of the entire Premises and
shall also provide its own janitorial and security services for the Buildings. Such utility use
shall include electricity, water, and gas use for lighting, incidental use and “HVAC,” as that term
is defined below. All such utility, janitorial and security payments shall be excluded from
Operating Expenses and shall be paid directly by Tenant prior to the date on which the same are due
to the utility provider janitorial company and/or security company, as applicable. Landlord and
Tenant hereby acknowledge that each portion of the Premises is separately metered or submetered.
Landlord shall not be required to provide any services other than with regard to its maintenance
and repair obligation relating to the Building Structure and the Common Areas.

     6.2 Overstandard Tenant Use; Tenant Maintained Building Systems; HVAC.

          6.2.1 Overstandard Tenant Use. The terms of this Section 6.2.1 shall be
applicable only to that portion of the Premises located in Building C. Tenant shall not, without

-28-

 

Landlord’s prior written consent, use heat-generating machines, machines other than normal
fractional horsepower office machines, or equipment or lighting other than Building standard lights
in the Premises, which may affect the temperature otherwise maintained by the air conditioning
system or increase the water normally furnished for the Premises by Landlord pursuant to the terms
of Section 6.1 of this Lease; provided, however, Landlord hereby consents to the use of
office machines installed in the Premises as of the date of this Lease. If such consent is given,
Landlord shall have the right to install supplementary air conditioning units or other facilities
in the Premises, including supplementary or additional metering devices, and the cost thereof,
including the cost of installation, operation and maintenance, increased wear and tear on existing
equipment and other similar charges, shall be paid by Tenant to Landlord upon billing by Landlord.
Tenant’s use of electricity shall never exceed the capacity of the feeders to the Project or the
risers or wiring installation, and subject to the terms of Section 29.32, below, Tenant
shall not install or use or permit the installation or use of any computer or electronic data
processing equipment in the Premises, without the prior written consent of Landlord. If Tenant
desires to use heat, ventilation or air conditioning during hours other than those for which
Landlord is obligated to supply such utilities pursuant to the terms of Section 6.1 of this
Lease, Tenant shall give Landlord such prior notice, if any, as Landlord shall from time to time
establish as appropriate, of Tenant’s desired use in order to supply such utilities, and Landlord
shall supply such utilities to Tenant at such hourly cost to Tenant (which shall be treated as
Additional Rent) as Landlord shall from time to time establish; provided, however, such hourly cost
will be limited to an amount reasonably determined by Landlord to reimburse Landlord for the excess
wear and tear on the applicable HVAC equipment (and shall expressly not include utility charges
since the Premises is separately metered).

          6.2.2 Tenant Maintained Building Systems; HVAC. The terms of this Section
6.2.2 shall be applicable only to that portion of the Premises located in Buildings A and F.
Tenant shall, at Tenant’s sole cost and expense, (i) maintain the Buildings’ mechanical,
electrical, life safety, plumbing, fire-sprinkler systems (except to the extent Landlord retains
repair and maintenance responsibility for life safety, plumbing and/or fire-sprinkler systems),
(ii) subject to limitations imposed by all governmental rules, regulations and guidelines
applicable thereto, maintain (itself or through a service provider) heating and air conditioning to
the Premises (“HVAC”), and (iii) maintain the remaining portions of the Premises which are not part
of the “Building Structure,” as that term is set forth in Article 7 of this Lease, to the
extent such Building Structure is to be maintained and repaired by Landlord.

     6.3 Tenant Maintained Security. Tenant hereby acknowledges that Landlord shall have
no obligation to provide guard service or other security measures for the benefit of the Premises,
the Building or the Project. Any such security measures for the benefit of the Premises, the
Building or the Project shall be provided by Tenant, at Tenant’s sole cost and expense. Tenant
hereby assumes all responsibility for the protection of Tenant and its agents, employees,
contractors, invitees and guests, and the property thereof, from acts of third parties, including
keeping doors locked and other means of entry to the Premises closed.

     6.4 Tenant Maintenance Standards. All Tenant maintained Building Systems, including
HVAC, shall be maintained in accordance with manufacturer specifications by Tenant in a
commercially reasonable condition. Tenant shall contract with a qualified, experienced
professional third party service company to perform its maintenance, repair and replacement

-29-

 

obligations hereunder with respect to the HVAC systems (which shall provide for and include,
without limitation, replacement of filters, oiling and lubricating of machinery, parts replacement,
adjustment of drive belts, oil changes and other preventive maintenance, including maintenance of
duct work, interior unit drains and caulking of sheet metal, and recaulking of jacks and vents on
an as-needed basis). Each and every service contract shall be provided to Landlord prior to
finalization and Landlord shall have the reasonable right to approve or disapprove of the form or
contents of the service contracts or the persons or entities to be engaged thereunder within five
(5) business days after receiving a copy of any such agreements from Tenant. In addition, upon
request from Landlord, Tenant shall provide to Landlord copies of any and all service contracts and
records of Tenant’s maintenance of such Building Systems. In connection with Tenant’s HVAC
maintenance obligations, Landlord shall provide Tenant access to the roofs of the applicable
Buildings. Tenant agrees that
Landlord shall not be liable for damages, by abatement of Rent (except as set forth in
Section 6.7, below) or otherwise, for failure to furnish or delay in furnishing any service
(including telephone and telecommunication services), or for any diminution in the quality or
quantity thereof, when such failure or delay or diminution is occasioned, in whole or in part, by
breakage, repairs, replacements, or improvements, by any strike, lockout or other labor trouble, by
inability to secure electricity, gas, water, or other fuel at the Building or Project after
reasonable effort to do so, by any riot or other dangerous condition, emergency, accident or
casualty whatsoever, by act or default of Tenant or other parties, or by any other cause beyond
Landlord’s reasonable control; and such failures or delays or diminution shall never be deemed to
constitute an eviction or disturbance of Tenant’s use and possession of the Premises or relieve
Tenant from paying Rent (except as set forth in Section 6.7, below) or performing any of
its obligations under this Lease. Furthermore, Landlord shall not be liable under any
circumstances for a loss of, or injury to, property or for injury to, or interference with,
Tenant’s business, including, without limitation, loss of profits, however occurring, through or in
connection with or incidental to a failure to furnish any of the services or utilities as set forth
in this Article 6.

     6.5 Tenant HVAC System. As a part of its Tenant Improvements (as defined in
Section 2.1 of the Tenant Work Letter) and subject to the terms of the Tenant Work Letter,
Tenant, at its sole expense, may install a supplemental HVAC system on the roof of Building F,
Building A and/or Building C, or otherwise in a location in the Premises approved by Landlord, for
the purpose of providing supplemental air-conditioning to the Premises (the “Tenant HVAC System”).
All aspects of the Tenant HVAC System (including, but not limited to, any connection to the
Building’s chilled water system) shall be subject to Landlord’s prior written approval, which
approval shall not be unreasonably withheld, conditioned or delayed, unless the structural aspects
of the Building, the Building systems and equipment, and/or the exterior appearance of the Building
will be affected, in which event Landlord’s approval may be withheld in Landlord’s sole and
absolute discretion. If required for such purpose, Tenant may connect into the Building’s chilled
water system, if and to the extent that Tenant’s use of chilled water pursuant to this Section
6.5 will not materially, adversely affect the chilled water system or the use thereof by other
tenants of the Building, if any, as determined by Landlord in Landlord’s sole discretion. If
Tenant connects into the Building’s chilled water system pursuant to the terms of the foregoing
sentence, then Landlord may install, at Tenant’s expense, a meter to measure Tenant’s use of
chilled water, and Tenant shall reimburse Landlord for Tenant’s use of chilled water at the cost
reasonably determined by Landlord. In addition, Landlord shall, at Tenant’s sole cost and expense,
separately meter the electricity utilized by the Tenant HVAC System, and

-30-

 

Tenant shall reimburse
Landlord for the cost as reasonably determined by Landlord of all electricity utilized by the
Tenant HVAC System. At Landlord’s election prior to the expiration or earlier termination of this
Lease, Tenant shall leave the Tenant HVAC System in the Premises upon the expiration or earlier
termination of this Lease, in which event the Tenant HVAC System shall be surrendered with the
Premises upon the expiration or earlier termination of this Lease, and Tenant shall thereafter have
no further rights with respect thereto. In the event that Landlord fails to elect to have the
Tenant HVAC System left in the Premises upon the expiration or earlier termination of this Lease,
then Tenant shall remove the Tenant HVAC System upon the expiration or earlier termination of this
Lease, and repair all damage to the Building resulting from such removal, at Tenant’s sole cost and
expense. Tenant shall be solely responsible, at Tenant’s sole cost and expense, for the
monitoring, operation, repair, replacement, and removal (subject to the foregoing terms of this
Section 6.5), of the Tenant HVAC System, and in no event shall the Tenant HVAC System
interfere with Landlord’s operation of the Building. Any reimbursements owing by Tenant to
Landlord pursuant to this Section 6.5 shall be payable by Tenant within ten (10) days of
Tenant’s receipt of an invoice therefor.

     6.6 Generator. Subject to the terms hereof and Applicable Laws, Tenant shall have the
right to install a generator (the “Generator”) in a location to be mutually and reasonably agreed
upon by Landlord and Tenant (the “Generator Area”); provided, however, if the Generator Area is
located in a project parking area, then the number of surface reserved parking passes allocated to
Tenant shall be reduced by the number of whole and/or partial parking spaces used to create the
Generator Area. Tenant shall be responsible for any and all costs, if any, incurred by Landlord as
a result of or in connection with Tenant’s installation, operation and/or use of the Generator.
Subject to Landlord’s prior approval of all plans and specifications, which approval shall not be
unreasonably withheld, and at Tenant’s sole cost and expense, Landlord shall permit Tenant to
install and maintain the Generator in the Generator Area, and connections between the Generator and
Landlord’s electrical systems in the Building(s), all in compliance with all Applicable Laws. Such
Generator shall be used by Tenant only during (i) testing and regular maintenance, and (ii) the
period of any
electrical power outage in the Building. Tenant shall be entitled to operate the Generator
and such connections to the Building for testing and regular maintenance only upon notice to
Landlord and at times reasonably approved by Landlord. Tenant shall submit the specifications for
design, operation, installation and maintenance of the connections to the Generator and facilities
related thereto to Landlord for Landlord’s consent, which consent will not be unreasonably withheld
or delayed and may be conditioned on Tenant complying with such reasonable requirements imposed by
Landlord, based on the advice of Landlord’s engineers, so that the Building’s systems or other
components of the Building are not adversely affected by the installation and operation of the
Generator. The cost of design (including engineering costs) and installation of the Generator and
the costs of the Generator itself shall be Tenant’s sole responsibility, but which costs shall be
deemed a “Tenant Improvement Allowance Item” pursuant to Section 2.2.1 of the Tenant Work Letter.
All repairs and maintenance of the Generator shall be the sole responsibility of Tenant, and
Landlord makes no representation or warranty with respect to such Generator. Tenant shall remove
the Generator and all related facilities and equipment upon the expiration or earlier termination
of this Lease and repair all damage to the Building and/or Project resulting from such removal and
restore all affected areas to their condition existing prior to Tenant’s installation of the
Generator, all at Tenant’s sole cost and expense. The terms of the preceding sentence shall
survive the

-31-

 

termination or earlier expiration of this Lease. The Generator shall be deemed to be a
part of the Premises for purposes of the indemnification and insurance provisions of this Lease,
and Tenant shall maintain, at Tenant’s cost, industry standard “boiler and machinery” insurance
coverage with respect thereto.

     6.7 Interruption of Use. If (i) Landlord fails to perform the obligations required of
Landlord under the TCCs of this Lease, (ii) such failure causes all or a portion of the Premises to
be untenantable and unusable by Tenant, and (iii) such failure relates to (A) the nonfunctioning of
the heat, ventilation, and air conditioning system in the Premises, the electricity in the
Premises, the nonfunctioning of the elevator service to the Premises, or (B) a failure to provide
access to the Premises, Tenant shall give Landlord notice (the “Initial Notice”), specifying such
failure to perform by Landlord (the “Abatement Event”). If Landlord has not cured such Abatement
Event within three (3) business days after the receipt of the Initial Notice (the “Eligibility
Period”), Tenant may deliver an additional notice to Landlord (the “Additional Notice”), specifying
such Abatement Event and Tenant’s intention to abate the payment of Rent under this Lease. If
Landlord does not cure such Abatement Event within two (2) business days of receipt of the
Additional Notice, Tenant may, upon written notice to Landlord, immediately abate Rent payable
under this Lease for that portion of the Premises rendered untenantable and not used by Tenant, for
the period beginning on the date three (3) business days after the Initial Notice to the earlier of
the date Landlord cures such Abatement Event or the date Tenant recommences the use of such portion
of the Premises. Such right to abate Rent shall be Tenant’s sole and exclusive remedy at law or in
equity for a Abatement Event. Except as provided in this Section 6.4, nothing contained
herein shall be interpreted to mean that Tenant is excused from paying Rent due hereunder.

ARTICLE 7

REPAIRS

     Tenant shall, at Tenant’s own expense, keep the Premises, including all improvements, fixtures
and furnishings therein, and the floor or floors of the Buildings on which the Premises are
located, in good order, repair and condition at all times during the Lease Term, normal wear and
tear, damage to the Premises which would be repaired under Article 11 hereof, excepted. In
addition, subject to Landlord’s repair obligations as set forth in this Article 7 and
Article 11, Tenant shall, at Tenant’s own expense, but under the supervision and subject to
the prior approval of Landlord, and within any reasonable period of time specified by Landlord,
promptly and adequately repair all damage to the Premises and replace or repair all damaged,
broken, or worn fixtures and appurtenances, except for damage caused by ordinary wear and tear or
beyond the reasonable control of Tenant; provided however, that, at Landlord’s option, or if Tenant
fails to make such repairs, Landlord may, after written notice to Tenant and Tenant’s failure to
repair within five (5) days thereafter, but need not, make such repairs and replacements, and
Tenant shall pay Landlord the cost thereof, including a percentage of the cost thereof (to be
uniformly established for the Buildings and/or the Project) sufficient to reimburse Landlord for
all overhead, general conditions, reasonable fees and other costs or expenses arising from
Landlord’s involvement with such repairs and replacements forthwith upon being billed for same.
Notwithstanding the foregoing, Landlord shall be responsible for repairs to
the exterior walls, foundation, roof and other structural elements of the Buildings, and the
structural portions of the

-32-

 

floors of the Buildings (collectively, the “Building Structure”), and
the systems and equipment of the Buildings and Common Areas (collectively the “Building Systems”),
except to the extent that such repairs are required due to the negligence or willful misconduct of
Tenant; provided, however, that if such repairs are due to the negligence or willful misconduct of
Tenant, Landlord shall nevertheless make such repairs at Tenant’s expense, or, if covered by
Landlord’s insurance, Tenant shall only be obligated to pay any deductible in connection therewith.
Landlord may, but shall not be required to, enter the Premises at all reasonable times to make
such repairs, alterations, improvements or additions to the Premises or to the Project or to any
equipment located in the Project as Landlord shall desire or deem necessary or as Landlord may be
required to do by governmental or quasi-governmental authority or court order or decree; provided,
however, except for (i) emergencies, (ii) repairs, alterations, improvements or additions required
by governmental or quasi-governmental authorities or court order or decree, or (iii) repairs which
are the obligation of Tenant hereunder, any such entry into the Premises by Landlord shall be
performed in a manner so as not to materially interfere with Tenant’s use of, or access to, the
Premises; provided that, with respect to items (ii) and (iii) above, Landlord shall use
commercially reasonable efforts to not materially interfere with Tenant’s use of, or access to, the
Premises. Tenant hereby waives any and all rights under and benefits of subsection 1 of Section
1932 and Sections 1941 and 1942 of the California Civil Code or under any similar law, statute, or
ordinance now or hereafter in effect.

ARTICLE 8

ADDITIONS AND ALTERATIONS

     8.1 Landlord’s Consent to Alterations. Tenant may not make any improvements,
alterations, additions or changes to the Premises or any mechanical, plumbing or HVAC facilities or
systems pertaining to the Premises (collectively, the “Alterations”) without first procuring the
prior written consent of Landlord to such Alterations, which consent shall be requested by Tenant
not less than fifteen (15) business days prior to the commencement thereof, and which consent shall
not be unreasonably withheld by Landlord, provided it shall be deemed reasonable for Landlord to
withhold its consent to any Alteration which adversely affects the structural portions or the
systems or equipment of the Buildings or is visible from the exterior of the Buildings.
Notwithstanding the foregoing, Tenant shall be permitted to make Alterations following ten (10)
business days notice to Landlord, but without Landlord’s prior consent, to the extent that such
Alterations do not adversely affect the systems and equipment of the Buildings, exterior appearance
of the Buildings, or structural aspects of the Buildings (the “Cosmetic Alterations”). The
construction of the initial improvements to the Premises shall be governed by the terms of the
Tenant Work Letter and not the terms of this Article 8.

     8.2 Manner of Construction. Landlord may impose, as a condition of its consent to any
and all Alterations or repairs of the Premises or about the Premises, such requirements as Landlord
in its reasonable discretion may deem desirable, including, but not limited to, the requirement
that Tenant utilize for such purposes only contractors reasonably approved by Landlord, and the
requirement that upon Landlord’s timely request (as more particularly set forth in, and subject to
the terms of, Section 8.5, below), Tenant shall, at Tenant’s expense, remove such
Alterations upon the expiration or any early termination of the Lease Term and return the affected
portion of the Premises to a building standard tenant improved condition as determined

-33-

 

by Landlord.
Tenant shall construct such Alterations and perform such repairs in a good and workmanlike manner,
in conformance with any and all applicable federal, state, county or municipal laws, rules and
regulations and pursuant to a valid building permit, issued by the City of Calabasas, all in
conformance with Landlord’s construction rules and regulations; provided, however, that prior to
commencing to construct any Alteration, Tenant shall meet with Landlord to discuss Landlord’s
design parameters and code compliance issues. In the event Tenant performs any Alterations in the
Premises which require or give rise to governmentally required changes to the “Base Building,” as
that term is defined below, then Landlord shall, at Tenant’s expense, make such changes to the Base
Building. The “Base Building” shall include the structural portions of the Buildings, and the
public restrooms, elevators, exit stairwells and the systems and equipment located in the internal
core of the Buildings on the floor or floors on which the Premises are located. In performing the
work of any such Alterations, Tenant shall have the work performed in such manner so as not to
obstruct access to the Project or any portion thereof, by any other tenant of the Project, and so
as not to obstruct the business of Landlord or other tenants in the Project. Tenant shall not use
(and upon notice from Landlord shall cease using) contractors, services, workmen, labor,
materials or equipment that, in Landlord’s reasonable judgment, would disturb labor harmony with
the workforce or trades engaged in performing other work, labor or services in or about the
Buildings or the Common Areas. In addition to Tenant’s obligations under Article 9 of this
Lease, upon completion of any Alterations, Tenant agrees to cause a Notice of Completion to be
recorded in the office of the Recorder of the County of Los Angeles in accordance with Section 3093
of the Civil Code of the State of California or any successor statute, and Tenant shall deliver to
the Project construction manager a reproducible copy of the “as built” drawings of the Alterations,
to the extent applicable, as well as all permits, approvals and other documents issued by any
governmental agency in connection with the Alterations.

     8.3 Payment for Improvements. If payment is made directly to contractors, Tenant
shall (i) comply with Landlord’s requirements for final lien releases and waivers in connection
with Tenant’s payment for work to contractors, and (ii) sign Landlord’s standard contractor’s rules
and regulations. If Tenant orders any work directly from Landlord, Tenant shall pay to Landlord an
amount equal to five percent (5%) of the cost of such work to compensate Landlord for all overhead,
general conditions, fees and other costs and expenses arising from Landlord’s involvement with such
work. If Tenant does not order any work directly from Landlord, Tenant shall reimburse Landlord
for Landlord’s reasonable, actual, out-of-pocket costs and expenses actually incurred in connection
with Landlord’s review of such work.

     8.4 Construction Insurance. In addition to the requirements of Article 10 of
this Lease, in the event that Tenant makes any Alterations, prior to the commencement of such
Alterations, Tenant shall provide Landlord with evidence that Tenant, or its general contractor,
carries “Builder’s All Risk” insurance in an amount reasonably approved by Landlord covering the
construction of such Alterations, and such other insurance as Landlord may reasonably require, it
being understood and agreed that all of such Alterations shall be insured by Tenant pursuant to
Article 10 of this Lease immediately upon completion thereof. In addition, Landlord may,
in its reasonable discretion, require Tenant to obtain a lien and completion bond or some alternate
form of security satisfactory to Landlord in an amount sufficient to ensure the lien-free
completion of such Alteration and naming Landlord as a co-obligee, but which lien and

-34-

 

completion
bond coverage shall not exceed one hundred percent (100%) of the cost of such Alteration.

     8.5 Landlord’s Property. Landlord and Tenant hereby acknowledge and agree that (i)
all Alterations, improvements, fixtures, equipment and/or appurtenances which may be installed or
placed in or about the Premises, from time to time, shall be at the sole cost of Tenant and shall
be and become part of the Premises and the property of Landlord, and (ii) the Tenant Improvements
to be constructed in the Premises pursuant to the TCCs of the Tenant Work Letter shall, upon
completion of the same, be and become a part of the Premises and the property of Landlord.
Furthermore, Landlord may, by written notice to Tenant prior to the end of the Lease Term, or given
following any earlier termination of this Lease, require Tenant, at Tenant’s expense, to remove any
Alterations or improvements in the Premises and to repair any damage to the Premises and Building
caused by such removal; provided, however, if, in connection with its notice to Landlord with
respect to any such Alterations or Cosmetic Alterations, (i) Tenant requests Landlord’s decision
with regard to the removal of such Alterations or Cosmetic Alterations, and (ii) Landlord
thereafter agrees in writing to waive the removal requirement with regard to such Alterations or
Cosmetic Alterations, then Tenant shall not be required to so remove such Alterations or Cosmetic
Alterations; provided further, however, Tenant shall have no obligation to remove any improvements
existing in the Premises as of the date of this Lease except the following: (A) bus bars in server
rooms including electrical back to panel; (B) supplemental air conditioning units with the
exception of the supplemental air conditioning units located on the third floor of Buildings A and
F; (C) all equipment and other racks; and (D) furniture systems including electrical back to
panels. If Tenant fails to complete such removal and/or to repair any damage caused by the removal
of any Alterations or improvements in the Premises, and return the affected portion of the Premises
to a building standard tenant improved condition as determined by Landlord, then Landlord may do so
and may charge the cost thereof to Tenant. Tenant hereby protects, defends, indemnifies and holds
Landlord harmless from any liability, cost, obligation, expense or claim of lien in any manner
relating to the installation, placement, removal or financing of any such Alterations,
improvements, fixtures and/or equipment in, on or about the Premises, which obligations of Tenant
shall survive the expiration or earlier termination of this Lease.

ARTICLE 9

COVENANT AGAINST LIENS

     Tenant shall keep the Project and Premises free from any liens or encumbrances arising out of
the work performed, materials furnished or obligations incurred by or on behalf of Tenant, and
shall protect, defend, indemnify and hold Landlord harmless from and against any claims,
liabilities, judgments or costs (including, without limitation, reasonable attorneys’ fees and
costs) arising out of same or in connection therewith. Tenant shall give Landlord notice at least
twenty (20) days prior to the commencement of any such work on the Premises (or such additional
time as may be necessary under applicable laws) to afford Landlord the opportunity of posting and
recording appropriate notices of non-responsibility. Tenant shall remove any such lien or
encumbrance by bond or otherwise within five (5) days after notice by Landlord, and if Tenant shall
fail to do so, Landlord may pay the amount necessary to remove such lien or encumbrance, without
being responsible for investigating the validity thereof. The amount so paid shall be

-35-

 

deemed
Additional Rent under this Lease payable upon demand, without limitation as to other remedies
available to Landlord under this Lease. Nothing contained in this Lease shall authorize Tenant to
do any act which shall subject Landlord’s title to the Buildings or Premises to any liens or
encumbrances whether claimed by operation of law or express or implied contract. Any claim to a
lien or encumbrance upon the Buildings or Premises arising in connection with any such work or
respecting the Premises not performed by or at the request of Landlord shall be null and void, or
at Landlord’s option shall attach only against Tenant’s interest in the Premises and shall in all
respects be subordinate to Landlord’s title to the Project, Buildings and Premises.

ARTICLE 10

INSURANCE

     10.1 Indemnification and Waiver. Tenant hereby assumes all risk of damage to property
or injury to persons in, upon or about the Premises from any cause whatsoever and agrees that
Landlord, its partners, subpartners and their respective officers, agents, servants, employees, and
independent contractors (collectively, “Landlord Parties”) shall not be liable for, and are hereby
released from any responsibility for, any damage either to person or property or resulting from the
loss of use thereof, which damage is sustained by Tenant or by other persons claiming through
Tenant; provided, however, the foregoing waiver and release shall not apply with respect to such
injury, death or damage to the extent caused by the gross negligence or willful misconduct of
Landlord or any Landlord Party. Tenant shall indemnify, defend, protect, and hold harmless the
Landlord Parties from any and all loss, cost, damage, expense and liability (including without
limitation court costs and reasonable attorneys’ fees) incurred in connection with or arising from
any cause in, on or about the Premises, any acts, omissions or negligence of Tenant or of any
person claiming by, through or under Tenant, or of the contractors, agents, servants, employees,
invitees, guests or licensees of Tenant or any such person, in, on or about the Project or any
breach of the TCCs of this Lease, either prior to, during, or after the expiration of the Lease
Term, provided that the terms of the foregoing indemnity shall not apply to the negligence or
willful misconduct of Landlord. Should Landlord be named as a defendant in any suit brought
against Tenant in connection with or arising out of Tenant’s occupancy of the Premises, Tenant
shall pay to Landlord its costs and expenses incurred in such suit, including without limitation,
its actual professional fees such as appraisers’, accountants’ and attorneys’ fees. Further,
Tenant’s agreement to indemnify Landlord pursuant to this Section 10.1 is not intended and
shall not relieve any insurance carrier of its obligations under policies required to be carried by
Tenant pursuant to the provisions of this Lease, to the extent such policies cover the matters
subject to Tenant’s indemnification obligations; nor shall they supersede any inconsistent
agreement of the parties set forth in any other provision of this Lease. The provisions of this
Section 10.1 shall survive the expiration or sooner termination of this Lease with respect
to any claims or liability arising in connection with any event occurring prior to such expiration
or termination. Notwithstanding anything to the contrary contained in this Lease, nothing in this
Lease shall impose any obligations on Tenant or Landlord to be responsible or liable for, and each
hereby releases the other from all liability for, consequential damages other than those
consequential damages for which Tenant may become liable under the terms of Article 16, below, or
incurred by Landlord in connection with any repair, physical construction or improvement work
performed by or on behalf of Tenant in the Project, but Tenant shall not be responsible for any
direct or consequential damages resulting from

-36-

 

Landlord’s or contractor’s acts or omissions in
connection with the completion by Landlord of the Tenant Improvements in the Premises pursuant to
the Tenant Work Letter.

     10.2 Landlord’s Fire, Casualty and Liability Insurance. Landlord shall carry
commercial general liability insurance with respect to the Buildings during the Lease Term, and
shall further insure the Buildings during the Lease Term against loss or damage due to fire and
other casualties covered within the classification of fire and extended coverage, vandalism
coverage and malicious mischief, sprinkler leakage, water damage and special extended coverage, for
full replacement value of the Buildings. Such coverage shall be in such amounts, from such
companies, and on such other terms and conditions, as Landlord may from time to time reasonably
determine. Additionally, at the option of Landlord, such insurance coverage may include the risks
of earthquakes and/or flood damage and additional hazards, a rental loss endorsement and one or
more loss payee endorsements in favor of the holders of any mortgages or deeds of trust encumbering
the interest of Landlord in the Buildings or the ground or underlying lessors of the Buildings, or
any portion thereof. Notwithstanding the foregoing provisions of this Section 10.2, the
coverage and amounts of insurance carried by Landlord in connection with the Buildings shall, at a
minimum, be comparable to the coverage and amounts of insurance which are carried by reasonably
prudent landlords of Comparable Buildings, and Worker’s Compensation and Employer’s Liability
coverage as required by applicable law. Tenant shall, at Tenant’s expense, comply with all
insurance company requirements pertaining to the use of the Premises. If Tenant’s conduct or use
of the Premises for other than typical office purposes causes any material increase in the premium
for such insurance policies then Tenant shall reimburse Landlord for any such increase; provided,
however, Landlord hereby acknowledges that Tenant’s use of the Premises since 2000 (pursuant to the
terms of the Existing Lease) has not caused an increase in Landlord’s insurance premiums. Tenant, at
Tenant’s expense, shall comply with all rules, orders, regulations or requirements of the American
Insurance Association (formerly the National Board of Fire Underwriters) and with any similar body.

     10.3 Tenant’s Insurance. Tenant shall maintain the following coverages in the
following amounts.

          10.3.1 Commercial General Liability Insurance covering the insured against claims of bodily
injury, personal injury and property damage (including loss of use thereof) arising out of Tenant’s
operations, and contractual liabilities (covering the performance by Tenant of its indemnity
agreements) including a Broad Form endorsement covering the insuring provisions of this Lease and
the performance by Tenant of the indemnity agreements set forth in Section 10.1 of this
Lease, for limits of liability not less than:

	 	 	 
	Bodily Injury and

	 	$5,000,000 each occurrence
	Property Damage Liability

	 	$5,000,000 annual aggregate
	 
	 	 
	Personal Injury Liability

	 	$5,000,000 each occurrence
	 

	 	$5,000,000 annual aggregate
	 

	 	0% Insured’s participation

-37-

 

          10.3.2 Physical Damage Insurance covering (i) all office furniture, business and trade
fixtures, office equipment, free-standing cabinet work, movable partitions, merchandise and all
other items of Tenant’s property on the Premises installed by, for, or at the expense of Tenant,
(ii) the “Tenant Improvements,” as that term is defined in Section 2.1 of the Tenant Work
Letter, and any other improvements which exist in the Premises as of the Lease Commencement Date
(excluding the Base Building) (the “Original Improvements”), and (iii) all other improvements,
alterations and additions to the Premises. Such insurance shall be written on an “all risks” of
physical loss or damage basis, for the full replacement cost value (subject to reasonable
deductible amounts) new without deduction for depreciation of the covered items and in amounts that
meet any co-insurance clauses of the policies of insurance and shall include coverage for damage or
other loss caused by fire or other peril including, but not limited to, vandalism and malicious
mischief, theft, water damage of any type, including sprinkler leakage, bursting or stoppage of
pipes, and explosion, and providing business interruption coverage for a period of one year.

          10.3.3 Worker’s Compensation and Employer’s Liability or other similar insurance pursuant to
all applicable state and local statutes and regulations, and Employer’s Liability or other similar
insurance pursuant to all applicable state and local statutes and regulations, with limits not less
than One Million and No/100 Dollars ($1,000,000.00).

          10.3.4 Comprehensive Automobile Liability Insurance covering all owned or hired vehicles with
the following limits of liability: One Million Dollars ($1,000,000.00) combined single limit for
bodily injury and property damage.

     10.4 Form of Policies. The minimum limits of policies of insurance required of Tenant
under this Lease shall in no event limit the liability of Tenant under this Lease. Such insurance
shall (i) name Landlord, and any other party the Landlord so specifies that has a material
financial interest in the Project, as an additional insured, including Landlord’s managing agent,
if any; (ii) specifically cover the liability assumed by Tenant under this Lease, including, but
not limited to, Tenant’s obligations under Section 10.1 of this Lease; (iii) be issued by
an insurance company having a rating of not less than A-X in Best’s Insurance Guide or which is
otherwise acceptable to Landlord and licensed to do business in the State of California; (iv) be
primary insurance as to all claims thereunder and provide that any insurance carried by Landlord is
excess and is non-contributing with any insurance requirement of Tenant; (v) be in form and content
reasonably acceptable to Landlord; and (vi) provide that said insurance shall not be canceled or
coverage changed unless ten (10) days’ prior written notice shall have been given to Landlord and
any mortgagee of Landlord, the identity of whom has been provided to Tenant in writing. Tenant
shall deliver said policy or policies or certificates thereof to Landlord on or before the Lease
Commencement Date and at least ten (10) days before the expiration dates thereof. In the event
Tenant shall fail to procure such insurance, or to deliver such policies or certificate, Landlord
may, at its option, after written notice to Tenant and Tenant’s failure to obtain such insurance
within five (5) days thereafter, procure such policies for the account of Tenant, and the cost
thereof shall be paid to Landlord within thirty (30) days after delivery to Tenant of bills
therefor.

     10.5 Subrogation. Landlord and Tenant intend that their respective property loss
risks shall be borne by reasonable insurance carriers to the extent above provided, and Landlord
and

-38-

 

Tenant hereby agree to look solely to, and seek recovery only from, their respective insurance
carriers in the event of a property loss to the extent that such coverage is agreed to be provided
hereunder. The parties each hereby waive all rights and claims against each other for such losses,
and waive all rights of subrogation of their respective insurers, provided such waiver of
subrogation shall not affect the right to the insured to recover thereunder. The parties agree
that their respective insurance policies are now, or shall be, endorsed such that the waiver of
subrogation shall not affect the right of the insured to recover thereunder, so long as no material
additional premium is charged therefor.

     10.6 Additional Insurance Obligations. Tenant shall carry and maintain during the
entire Lease Term, at Tenant’s sole cost and expense, increased amounts of the insurance required
to be carried by Tenant pursuant to this Article 10 and such other reasonable types of
insurance coverage and in such reasonable amounts covering the Premises and Tenant’s operations
therein, as may be reasonably requested by Landlord, but in no event in excess of the amounts and
types of insurance then being required by landlords of other Comparable Buildings.

ARTICLE 11

DAMAGE AND DESTRUCTION

     11.1 Repair of Damage to Premises by Landlord. Tenant shall promptly notify Landlord
of any damage to the Premises resulting from fire or any other casualty. If the Premises or any
Common Areas serving or providing access to the Premises shall be damaged by fire or other
casualty, Landlord shall promptly and diligently, subject to reasonable delays for insurance
adjustment or other matters beyond Landlord’s reasonable control, and subject to all other terms of
this Article 11, restore the Base Building and such Common Areas. Such restoration shall
be to substantially the same condition of the Base Building and the Common Areas prior to the
casualty, except for modifications required by zoning and building codes and other laws or by the
holder of a mortgage on the Buildings or Project or any other modifications to the Common Areas
deemed desirable by Landlord, which are consistent with the character of the Project, provided that
access to the Premises and any common restrooms serving
the Premises shall not be materially impaired. Upon the occurrence of any damage to the
Premises, upon notice (the “Landlord Repair Notice”) to Tenant from Landlord, Tenant shall assign
to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under
Tenant’s insurance required under Section 10.3 of this Lease, and Landlord shall repair any
injury or damage to the Tenant Improvements and the Original Improvements installed in the Premises
and shall return such Tenant Improvements and Original Improvements to their original condition;
provided that if the cost of such repair by Landlord exceeds the amount of insurance proceeds
received by Landlord from Tenant’s insurance carrier, as assigned by Tenant, the cost of such
repairs shall be paid by Tenant to Landlord prior to Landlord’s commencement of repair of the
damage. In the event that Landlord does not deliver the Landlord Repair Notice within sixty (60)
days following the date the casualty becomes known to Landlord (the “60-Day Notice Period”), Tenant
shall, at its sole cost and expense, repair any injury or damage to the Tenant Improvements and the
Original Improvements installed in the Premises and shall return such Tenant Improvements and
Original Improvements to their original condition. Whether or not Landlord delivers a Landlord
Repair Notice, prior to the commencement of construction, Tenant shall submit to Landlord, for
Landlord’s review and approval, all plans, specifications and

-39-

 

working drawings relating thereto,
and Landlord shall select the contractors to perform such improvement work. Landlord shall not be
liable for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant’s business
resulting in any way from such damage or the repair thereof; provided however, that if such fire or
other casualty shall have damaged the Premises or Common Areas necessary to Tenant’s occupancy, and
the Premises are not occupied by Tenant as a result thereof, then during the time and to the extent
the Premises are unfit for occupancy, the Rent shall be abated in proportion to the ratio that the
amount of rentable square feet of the Premises which is unfit for occupancy for the purposes
permitted under this Lease bears to the total rentable square feet of the Premises. In the event
that Landlord shall not deliver the Landlord Repair Notice, Tenant’s right to rent abatement
pursuant to the preceding sentence shall terminate as of the date upon which Tenant reasonably
should have completed repairs to the Premises, assuming that Tenant used reasonable due diligence
in connection with such repairs, but taking into consideration any delay in the commencement of
such repairs resulting from the 60-Day Notice Period.

     11.2 Landlord’s Option to Repair. Notwithstanding the terms of Section 11.1
of this Lease, Landlord may elect not to rebuild and/or restore the Premises, Buildings and/or
Project, and instead terminate this Lease, by notifying Tenant in writing of such termination
within sixty (60) days after the date of discovery of the damage, such notice to include a
termination date giving Tenant sixty (60) days to vacate the Premises, but Landlord may so elect
only if the Buildings or Project shall be damaged by fire or other casualty or cause, whether or
not the Premises are affected, and one or more of the following conditions is present: (i) in
Landlord’s reasonable judgment, repairs cannot reasonably be completed within one hundred eighty
(180) days after the date of discovery of the damage (when such repairs are made without the
payment of overtime or other premiums); (ii) the holder of any mortgage on the Buildings or Project
or ground lessor with respect to the Buildings or Project shall require that the insurance proceeds
or any portion thereof be used to retire the mortgage debt, or shall terminate the ground lease, as
the case may be; (iii) the damage is not fully covered by Landlord’s insurance policies (unless
such failure of coverage is a result of Landlord’s failure to maintain the policies of insurance
required to be maintained by Landlord pursuant to the terms of Section 10.2, above); or (iv) the
damage occurs during the last twelve (12) months of the Lease Term; provided, however, that if
Landlord does not elect to terminate this Lease pursuant to Landlord’s termination right as
provided above, and the repairs cannot, in the reasonable opinion of Landlord, be completed within
one hundred eighty (180) days after being commenced, Tenant may elect, no earlier than sixty (60)
days after the date of the damage and not later than ninety (90) days after the date of such
damage, to terminate this Lease by written notice to Landlord effective as of the date specified in
the notice, which date shall not be less than thirty (30) days nor more than sixty (60) days after
the date such notice is given by Tenant. Furthermore, if neither Landlord nor Tenant has
terminated this Lease, and the repairs are not actually completed within such 180-day period,
Tenant shall have the right to terminate this Lease during the first five (5) business days of each
calendar month following the end of such period until such time as the repairs are complete, by
notice to Landlord (the “Damage Termination Notice”), effective as of a date set forth in the
Damage Termination Notice (the “Damage Termination Date”), which Damage Termination Date shall not
be less than ten (10) business days following the end of each such month. Notwithstanding the
foregoing, if Tenant delivers a Damage Termination Notice to Landlord, then Landlord shall have the
right to suspend the occurrence of the Damage Termination Date for a period ending thirty (30) days
after the Damage Termination Date set forth in the Damage Termination Notice

-40-

 

by delivering to
Tenant, within five (5) business days of Landlord’s receipt of the Damage Termination Notice, a
certificate of Landlord’s contractor responsible for the repair of the damage
certifying that it is such contractor’s good faith judgment that the repairs shall be
substantially completed within thirty (30) days after the Damage Termination Date. If repairs
shall be substantially completed prior to the expiration of such thirty-day period, then the Damage
Termination Notice shall be of no force or effect, but if the repairs shall not be substantially
completed within such thirty-day period, then this Lease shall terminate upon the expiration of
such thirty-day period. At any time, from time to time, after the date occurring sixty (60) days
after the date of the damage, Tenant may request that Landlord inform Tenant of Landlord’s
reasonable opinion of the date of completion of the repairs and Landlord shall respond to such
request within five (5) business days. Notwithstanding the provisions of this Section
11.2, Tenant shall have the right to terminate this Lease under this Section 11.2 only
if each of the following conditions is satisfied: (a) the damage to the Project by fire or other
casualty was not caused by an intentional act or omission of Tenant or its partners or subpartners
and their respective officers, agents, servants, employees, and independent contractors; (b) as a
result of the damage, Tenant cannot reasonably conduct its business from the Premises; and, (c) as
a result of the damage to the Project, Tenant does not occupy or use the Premises at all. In the
event this Lease is terminated in accordance with the terms of this Section 11.2, Tenant
shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to
Tenant under Tenant’s insurance required under items (ii) and (iii) of Section 10.3.2 of
this Lease.

     11.3 Waiver of Statutory Provisions. The provisions of this Lease, including this
Article 11, constitute an express agreement between Landlord and Tenant with respect to any
and all damage to, or destruction of, all or any part of the Premises, the Buildings or the
Project, and any statute or regulation of the State of California, including, without limitation,
Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or
obligations concerning damage or destruction in the absence of an express agreement between the
parties, and any other statute or regulation, now or hereafter in effect, shall have no application
to this Lease or any damage or destruction to all or any part of the Premises, the Buildings or the
Project.

ARTICLE 12

NONWAIVER

     No provision of this Lease shall be deemed waived by either party hereto unless expressly
waived in a writing signed thereby. The waiver by either party hereto of any breach of any term,
covenant or condition herein contained shall not be deemed to be a waiver of any subsequent breach
of same or any other term, covenant or condition herein contained. The subsequent acceptance of
Rent hereunder by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of
any term, covenant or condition of this Lease, other than the failure of Tenant to pay the
particular Rent so accepted, regardless of Landlord’s knowledge of such preceding breach at the
time of acceptance of such Rent. No acceptance of a lesser amount than the Rent herein stipulated
shall be deemed a waiver of Landlord’s right to receive the full amount due, nor shall any
endorsement or statement on any check or payment or any letter accompanying such check or payment
be deemed an accord and satisfaction, and Landlord may

-41-

 

accept such check or payment without
prejudice to Landlord’s right to recover the full amount due. No receipt of monies by Landlord
from Tenant after the termination of this Lease shall in any way alter the length of the Lease Term
or of Tenant’s right of possession hereunder, or after the giving of any notice shall reinstate,
continue or extend the Lease Term or affect any notice given Tenant prior to the receipt of such
monies, it being agreed that after the service of notice or the commencement of a suit, or after
final judgment for possession of the Premises, Landlord may receive and collect any Rent due, and
the payment of said Rent shall not waive or affect said notice, suit or judgment.

ARTICLE 13

CONDEMNATION

     If the whole or any material part of the Premises, Buildings or Project shall be taken by
power of eminent domain or condemned by any competent authority for any public or quasi-public use
or purpose, or if any adjacent property or street shall be so taken or condemned, or reconfigured
or vacated by such authority in such manner as to require the use, reconstruction or remodeling of
any part of the Premises, Buildings or Project, in such a manner as to have a material adverse
impact on Landlord’s ability to economically operate the Project in the manner required
under this Lease, or if Landlord shall grant a deed or other instrument in lieu of such taking
by eminent domain or condemnation, Landlord shall have the option to terminate this Lease effective
as of the date possession is required to be surrendered to the authority. If a material portion of
the Premises or Project is taken, or if Tenant’s use of or access to the Premises or Project is
materially impaired, in each case for a period in excess of thirty (30) days, Tenant shall have the
option to terminate this Lease effective as of the date possession is required to be surrendered to
the authority. Tenant shall not because of such taking assert any claim against Landlord or the
authority for any compensation because of such taking and Landlord shall be entitled to the entire
award or payment in connection therewith, except that Tenant shall have the right to file any
separate claim available to Tenant for (i) Tenant’s loss of goodwill; (ii) Tenant’s loss of
business and business interruption, (iii) any taking of Tenant’s personal property and fixtures
belonging to Tenant and removable by Tenant upon expiration of the Lease Term pursuant to the terms
of this Lease, and (iv) for moving expenses. All Rent shall be apportioned as of the date of such
termination. If any part of the Premises shall be taken, and this Lease shall not be so
terminated, the Rent shall be proportionately abated. Tenant hereby waives any and all rights it
might otherwise have pursuant to Section 1265.130 of The California Code of Civil Procedure.
Notwithstanding anything to the contrary contained in this Article 13, in the event of a
temporary taking of all or any portion of the Premises for a period of thirty (30) days or less,
then this Lease shall not terminate but the Base Rent and the Additional Rent shall be abated for
the period of such taking in proportion to the ratio that the amount of rentable square feet of the
Premises taken bears to the total rentable square feet of the Premises. Landlord shall be entitled
to receive the entire award made in connection with any such temporary taking.

-42-

 

ARTICLE 14

ASSIGNMENT AND SUBLETTING

     14.1 Transfers. Tenant shall not, without the prior written consent of Landlord,
assign, mortgage, pledge, hypothecate, encumber, or permit any lien to attach to, or otherwise
transfer, this Lease or any interest hereunder, permit any assignment, or other transfer of this
Lease or any interest hereunder by operation of law, sublet the Premises or any part thereof, or
enter into any license or concession agreements or otherwise permit the occupancy or use of the
Premises or any part thereof by any persons other than Tenant and its employees and contractors
(all of the foregoing are hereinafter sometimes referred to collectively as “Transfers” and any
person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a
“Transferee”). If Tenant desires Landlord’s consent to any Transfer, Tenant shall notify Landlord
in writing, which notice (the “Transfer Notice”) shall include (i) the proposed effective date of
the Transfer, which shall not be less than thirty (30) days nor more than one hundred eighty (180)
days after the date of delivery of the Transfer Notice, (ii) a description of the portion of the
Premises to be transferred (the “Subject Space”), (iii) all of the terms of the proposed Transfer
and the consideration therefor, including calculation of the “Transfer Premium”, as that term is
defined in Section 14.3 below, in connection with such Transfer, the name and address of
the proposed Transferee, and a copy of all existing executed and/or proposed documentation
pertaining to the proposed Transfer, including all existing operative documents to be executed to
evidence such Transfer or the agreements incidental or related to such Transfer, (iv) reasonable
information demonstrating the financial responsibility of the proposed Transferee, and the nature
of such Transferee’s business and proposed use of the Subject Space and (v) an executed estoppel
certificate from Tenant in the form attached hereto as Exhibit E. Landlord shall respond
to any such Transfer Notice within thirty (30) days after Landlord’s receipt of the same (and all
of the items required to be provided in connection therewith as set forth above). Any Transfer,
except for “Non-Transfers” pursuant to the terms and conditions of Article 14.8, below,
made without Landlord’s prior written consent, which consent shall not be unreasonably withheld,
conditioned or delayed, shall, at Landlord’s option, be null, void and of no effect, and shall, at
Landlord’s option, constitute a default by Tenant under this Lease. Whether or not Landlord
consents to any proposed Transfer, Tenant shall pay Landlord’s review and processing fees, as well
as any reasonable professional fees (including, without limitation, reasonable attorneys’,
accountants’, architects’, engineers’ and consultants’ fees) incurred by Landlord, within thirty
(30) days after written request by Landlord.

     14.2 Landlord’s Consent. Landlord shall not unreasonably withhold its consent to any
proposed Transfer of the Subject Space to the Transferee on the terms specified in the Transfer
Notice. Without limitation as to other reasonable grounds for withholding consent, the parties
hereby agree that it shall be reasonable under this
Lease and under any applicable law for Landlord to withhold consent to any proposed Transfer
where one or more of the following apply:

          14.2.1 The Transferee is of a character or reputation or engaged in a business which is not
consistent with the quality of the Buildings or the Project as reflected by the then existing
tenants of the Project with respect to comparable space, and of the Comparable Buildings;

-43-

 

          14.2.2 The Transferee intends to use the Subject Space for purposes which are not permitted
under this Lease;

          14.2.3 The Transferee is either a governmental agency or instrumentality thereof; provided,
however, that Tenant shall be entitled to assign, sublet or otherwise transfer to a governmental
agency or instrumentality thereof to the extent Landlord has leased or has permitted the lease of
space to a comparable (in terms of security, foot traffic, prestige, eminent domain and function
oriented issues) governmental agency or instrumentality thereof in comparably located space of
comparable size;

          14.2.4 The Transferee is not a party of reasonable financial worth and/or financial stability
in light of the responsibilities to be undertaken in connection with the Transfer on the date
consent is requested;

          14.2.5 The proposed Transfer would cause a violation of another lease for space in the
Project, or would give an occupant of the Project a right to cancel its lease; or

          14.2.6 Either the proposed Transferee, or any person or entity which directly or indirectly,
controls, is controlled by, or is under common control with, the proposed Transferee, (i) occupies
space in the Project at the time of the request for consent, or (ii) is negotiating with Landlord
to lease space in the Project at such time, or (iii) has negotiated with Landlord during the six
(6)-month period immediately preceding the Transfer Notice, but with regard to each of conditions
(i), (ii) and (iii) above, only to the extent Landlord has comparable space in the Project for such
proposed Transferee.

     If Landlord consents to any Transfer pursuant to the terms of this Section 14.2
(and does not exercise any recapture rights Landlord may have under Section 14.4 of this
Lease), Tenant may within six (6) months after Landlord’s consent, but not later than the
expiration of said six-month period, enter into such Transfer of the Premises or portion thereof,
upon substantially the same terms and conditions as are set forth in the Transfer Notice furnished
by Tenant to Landlord pursuant to Section 14.1 of this Lease, provided that if there are
any changes in the terms and conditions from those specified in the Transfer Notice (i) such that
Landlord would initially have been entitled to refuse its consent to such Transfer under this
Section 14.2, or (ii) which would cause the proposed Transfer to be more favorable to the
Transferee than the terms set forth in Tenant’s original Transfer Notice, Tenant shall again submit
the Transfer to Landlord for its approval and other action under this Article 14 (including
Landlord’s right of recapture, if any, under Section 14.4 of this Lease). Notwithstanding
anything to the contrary in this Lease, if Tenant or any proposed Transferee claims that Landlord
has unreasonably withheld or delayed its consent under Section 14.2 or otherwise has
breached or acted unreasonably under this Article 14, their sole remedies shall be a
declaratory judgment and an injunction for the relief sought without any monetary damages, and
Tenant hereby waives all other remedies, including, without limitation, any right at law or equity
to terminate this Lease, on its own behalf and, to the extent permitted under all applicable laws,
on behalf of the proposed Transferee. Tenant shall indemnify, defend and hold harmless Landlord
from any and all liability, losses, claims, damages, costs, expenses, causes of action and
proceedings involving any third party or parties
(including without limitation Tenant’s proposed subtenant or assignee) who claim they were
damaged by Landlord’s wrongful withholding or conditioning of Landlord’s consent.

-44-

 

     14.3 Transfer Premium. If Landlord consents to a Transfer, as a condition
thereto which the parties hereby agree is reasonable, Tenant shall pay to Landlord fifty percent
(50%) of any “Transfer Premium,” as that term is defined in this Section 14.3, received by
Tenant from such Transferee; provided, however, if Tenant (A) exercises its right of first offer
pursuant to the terms of Section 1.3 of this Lease, above, and thereafter sublets the First
Offer Space to a subtenant, (B) exercises its right of first refusal pursuant to the terms of
Section 1.4 of this Lease, above, and thereafter sublets the First Refusal Space to a
subtenant, (C) installs Rooftop Equipment (or has such Rooftop Equipment installed) on behalf of a
subtenant pursuant to Article 22, (D) installs Tenant Signage (or has such Tenant Signage
installed) on behalf of a subtenant pursuant to Article 23, or (E) allows a subtenant to park in
reserved parking spaces acquired by Tenant pursuant to its Parking ROFO, then the Transfer Premium
shall be one hundred percent (100%). “Transfer Premium” shall mean all rent, additional rent or
other consideration payable by such Transferee in connection with the Transfer in excess of the
Rent and Additional Rent payable by Tenant under this Lease during the term of the Transfer on a
per rentable square foot basis if less than all of the Premises is transferred, after deducting the
reasonable expenses incurred by Tenant in connection with the Transfer (including, without
limitation, legal fees) for (i) any changes, alterations and improvements to the Premises in
connection with the Transfer, (ii) any free base rent and other concessions provided to the
Transferee, and (iii) any brokerage commissions in connection with the Transfer. “Transfer
Premium” shall also include, but not be limited to, key money, bonus money or other cash
consideration paid by Transferee to Tenant in connection with such Transfer, and any payment in
excess of fair market value for services rendered by Tenant to Transferee or for assets, fixtures,
inventory, equipment, or furniture transferred by Tenant to Transferee in connection with such
Transfer. In the calculations of the Rent (as it relates to the Transfer Premium calculated under
this Section 14.3), and the Transferee’s Rent and Quoted Rent under Section 14.2 of
this Lease, the Rent paid during each annual period for the Subject Space, and the Transferee’s
Rent and the Quoted Rent, shall be computed after adjusting such rent to the actual effective rent
to be paid, taking into consideration any and all leasehold concessions granted in connection
therewith, including, but not limited to, any rent credit and tenant improvement allowance. For
purposes of calculating any such effective rent all such concessions shall be amortized on a
straight-line basis over the relevant term.

     14.4 Landlord’s Option as to Subject Space. Notwithstanding anything to the contrary
contained in this Article 14, in the event Tenant request Landlord consent to a Transfer
(i) with respect to any space located in Building A, or (ii) with respect to any space located in
Building C, or (iii) of more than a full floor with respect to space located in Building F, then
Landlord shall have the option, by giving written notice to Tenant within twenty (20) days after
receipt of the applicable Transfer Notice, to recapture the Subject Space. Such recapture notice
shall cancel and terminate this Lease with respect to the Subject Space as of the date stated in
the Transfer Notice as the effective date of the proposed Transfer until the last day of the term
of the Transfer as set forth in the Transfer Notice (or at Landlord’s option, shall cause the
Transfer to be made to Landlord or its agent, in which case the parties shall execute the Transfer
documentation promptly thereafter). In the event of a recapture by Landlord, if this Lease shall
be canceled with
respect to less than the entire Premises, the Rent reserved herein shall be prorated on the
basis of the number of rentable square feet retained by Tenant in proportion to the number of
rentable square feet contained in the Premises, and this Lease as so amended shall continue
thereafter in full force and effect, and upon request of either party, the parties shall execute written

-45-

 

confirmation of the same. If Landlord declines, or fails to elect in a timely manner to
recapture the Subject Space under this Section 14.4, then, provided Landlord has consented
to the proposed Transfer, Tenant shall be entitled to proceed to transfer the Subject Space to the
proposed Transferee, subject to provisions of this Article 14.

     14.5 Effect of Transfer. If Landlord consents to a Transfer, (i) the TCCs of this
Lease shall in no way be deemed to have been waived or modified, (ii) such consent shall not be
deemed consent to any further Transfer by either Tenant or a Transferee, (iii) Tenant shall deliver
to Landlord, promptly after execution, an original executed copy of all documentation pertaining to
the Transfer in form reasonably acceptable to Landlord, (iv) Tenant shall furnish upon Landlord’s
request a complete statement, certified by an independent certified public accountant, or Tenant’s
chief financial officer, setting forth in detail the computation of any Transfer Premium Tenant has
derived and shall derive from such Transfer, and (v) no Transfer relating to this Lease or
agreement entered into with respect thereto, whether with or without Landlord’s consent, shall
relieve Tenant or any guarantor of the Lease from any liability under this Lease, including,
without limitation, in connection with the Subject Space. Landlord or its authorized
representatives shall have the right at all reasonable times to audit the books, records and papers
of Tenant relating to any Transfer, and shall have the right to make copies thereof. If the
Transfer Premium respecting any Transfer shall be found understated, Tenant shall, within thirty
(30) days after demand, pay the deficiency, and if understated by more than three and one-half
percent (3.5%), Tenant shall pay Landlord’s costs of such audit.

     14.6 Additional Transfers. For purposes of this Lease, the term “Transfer” shall also
include (i) if Tenant is a partnership, the withdrawal or change, voluntary, involuntary or by
operation of law, of fifty percent (50%) or more of the partners, or transfer of fifty percent
(50%) or more of partnership interests, within a twelve (12)-month period, or the dissolution of
the partnership without immediate reconstitution thereof, and (ii) if Tenant is a closely held
corporation (i.e., whose stock is not publicly held and not traded through an exchange or over the
counter), (A) the dissolution of Tenant in a manner that does not result in a continuing entity
that would be liable under the terms of this Lease, or (B) the sale or other transfer of an
aggregate of fifty percent (50%) or more of the voting shares of Tenant (other than to immediate
family members by reason of gift or death), within a twelve (12)-month period, or (C) the sale,
mortgage, hypothecation or pledge of an aggregate of fifty percent (50%) or more of the value of
the unencumbered assets of Tenant within a twelve (12)-month period.

     14.7 Occurrence of Default. Any Transfer hereunder shall be subordinate and subject
to the provisions of this Lease, and if this Lease shall be terminated during the term of any
Transfer, Landlord shall have the right to: (i) treat such Transfer as cancelled and repossess the
Subject Space by any lawful means, or (ii) require that such Transferee attorn to and recognize
Landlord as its landlord under any such Transfer. If Tenant shall be in default under this Lease,
Landlord is hereby irrevocably authorized, as Tenant’s agent and attorney-in-fact, to direct any
Transferee to make all payments under or in connection with the Transfer directly to Landlord
(which Landlord shall apply towards Tenant’s obligations under this Lease) until such default
is cured. Such Transferee shall rely on any representation by Landlord that Tenant is in default
hereunder, without any need for confirmation thereof by Tenant. Upon any assignment, the assignee
shall assume in writing all obligations and covenants of Tenant thereafter to be performed or
observed under this Lease. No collection or acceptance of rent by Landlord from

-46-

 

any Transferee
shall be deemed a waiver of any provision of this Article 14 or the approval of any
Transferee or a release of Tenant from any obligation under this Lease, whether theretofore or
thereafter accruing. In no event shall Landlord’s enforcement of any provision of this Lease
against any Transferee be deemed a waiver of Landlord’s right to enforce any term of this Lease
against Tenant or any other person. If Tenant’s obligations hereunder have been guaranteed,
Landlord’s consent to any Transfer shall not be effective unless the guarantor also consents to
such Transfer.

     14.8 Non-Transfers. Notwithstanding anything to the contrary contained in this
Article 14, (i) an assignment or subletting of all or a portion of the Premises to an
affiliate of Tenant (an entity which is controlled by, controls, or is under common control with,
Tenant), (ii) an assignment of the Premises to an entity which acquires all or substantially all of
the assets or interests (partnership, stock or other) of Tenant, (iii) an assignment of the
Premises to an entity which is the resulting entity of a merger or consolidation of Tenant, or (iv)
a sale of corporate shares of capital stock in Tenant in connection with an transaction resulting
in Tenant being a privately held corporation, shall not be deemed a Transfer under this Article
14 (any such assignee or sublessee described in items (i) through (iv) of this Section
14.8 hereinafter referred to as a “Permitted Non-Transferee”), provided that (a) Tenant
notifies Landlord of any such assignment or sublease and promptly supplies Landlord with any
documents or information reasonably requested by Landlord regarding such transfer or transferee as
set forth above, (b) such assignment or sublease is not a subterfuge by Tenant to avoid its
obligations under this Lease, (c) any transferee under this Section 14.8 shall be of a
character and reputation consistent with the quality of the Building, and (d) such transferee shall
have a tangible net worth (not including goodwill as an asset) computed in accordance with
generally accepted accounting principles (“Net Worth”) at least equal to the greater of (1) the Net
Worth of Tenant immediately prior to such assignment or sublease, and (2) the Net Worth of the
Original Tenant on the date of this Lease. An assignee of Tenant’s entire interest in this Lease
who qualifies as a Permitted Non-Transferee may also be referred to herein as a “Non-Transferee
Assignee.” “Control,” as used in this Section 14.8, shall mean the ownership, directly or
indirectly, of at least fifty-one percent (51%) of the voting securities of, or possession of the
right to vote, in the ordinary direction of its affairs, of at least fifty-one percent (51%) of the
voting interest in, any person or entity.

ARTICLE 15

SURRENDER OF PREMISES; OWNERSHIP AND 

REMOVAL OF TRADE FIXTURES

     15.1 Surrender of Premises. No act or thing done by Landlord or any agent or employee
of Landlord during the Lease Term shall be deemed to constitute an acceptance by Landlord of a
surrender of the Premises unless such intent is specifically acknowledged in
writing by Landlord. The delivery of keys to the Premises to Landlord or any agent or
employee of Landlord shall not constitute a surrender of the Premises or effect a termination of
this Lease, whether or not the keys are thereafter retained by Landlord, and notwithstanding such
delivery Tenant shall be entitled to the return of such keys at any reasonable time upon request
until this Lease shall have been properly terminated. The voluntary or other surrender of this
Lease by Tenant, whether accepted by Landlord or not, or a mutual termination hereof, shall not
work a

-47-

 

merger, and at the option of Landlord shall operate as an assignment to Landlord of all
subleases or subtenancies affecting the Premises or terminate any or all such sublessees or
subtenancies.

     15.2 Removal of Tenant Property by Tenant. Upon the expiration of the Lease Term, or
upon any earlier termination of this Lease, Tenant shall, subject to the provisions of this
Article 15, quit and surrender possession of the Premises to Landlord in as good order and
condition as when Tenant took possession and as thereafter improved by Landlord and/or Tenant,
reasonable wear and tear and repairs which are specifically made the responsibility of Landlord
hereunder excepted. Upon such expiration or termination, Tenant shall, without expense to
Landlord, remove or cause to be removed from the Premises all debris and rubbish, and such items of
furniture, equipment, cabling (data, voice, electrical, etc), business and trade fixtures,
free-standing cabinet work, movable partitions and other articles of personal property owned by
Tenant or installed or placed by Tenant at its expense in the Premises, and such similar articles
of any other persons claiming under Tenant, as Landlord may, in its sole discretion, require to be
removed, and Tenant shall repair at its own expense all damage to the Premises and Buildings
resulting from such removal.

ARTICLE 16

HOLDING OVER

     If Tenant holds over in all or any portion of the Premises after the expiration of the Lease
Term or earlier termination thereof, with or without the express or implied consent of Landlord,
such tenancy shall be from month-to-month only, and shall not constitute a renewal hereof or an
extension for any further term, and in such case Rent shall be payable at a monthly rate equal to
the product of (i) the Rent applicable during the last rental period of the Lease Term under this
Lease, and (ii) a percentage equal to one hundred fifty percent (150%). Such month-to-month
tenancy shall be subject to every other applicable term, covenant and agreement contained herein.
Nothing contained in this Article 16 shall be construed as consent by Landlord to any
holding over by Tenant, and Landlord expressly reserves the right to require Tenant to surrender
possession of the Premises to Landlord as provided in this Lease upon the expiration or other
termination of this Lease. The provisions of this Article 16 shall not be deemed to limit
or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If
Tenant fails to surrender the Premises upon the termination or expiration of this Lease, in
addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend,
indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys’ fees)
and liability resulting from such failure, including, without limiting the generality of the
foregoing, any claims made by any succeeding tenant founded upon such failure to surrender and any
lost profits to Landlord resulting therefrom.

ARTICLE 17

ESTOPPEL CERTIFICATES

     Within ten (10) business days following a request in writing by Landlord, Tenant shall
execute, acknowledge and deliver to Landlord an estoppel certificate, which, as submitted by
Landlord, shall be substantially in the form of Exhibit E, attached hereto (or such other

-48-

 

commercially reasonable form as may be required by any prospective mortgagee or purchaser of the
Project, or any portion thereof), indicating therein any exceptions thereto that may exist at that
time, and shall also contain any other information reasonably requested by Landlord or Landlord’s
mortgagee or prospective mortgagee. Any such certificate may be relied upon by any prospective
mortgagee or purchaser of all or any portion of the Project. Tenant shall execute and deliver
whatever other instruments may be reasonably required for such purposes. If at any time during the
Lease Term, Landlord elects to sell or refinance the Project or any Building, Landlord may require
Tenant to provide Landlord with a current financial statement and financial statements of the two
(2) years prior to the current financial statement year. Such statements shall be prepared in
accordance with generally accepted accounting principles and, if such is the normal practice of
Tenant, shall be audited by an independent certified public accountant. Notwithstanding the
foregoing, in the event that (i) stock in the entity which constitutes Tenant under this Lease (as
opposed to an entity that “controls” Tenant or is otherwise an “affiliate” of Tenant, as those
terms are defined in Section 14.8 of this Lease) is publicly traded on a national stock
exchange, and (ii) Tenant has it own, separate and distinct 10K and 10Q filing requirements (as
opposed joint or cumulative filings with an entity that controls Tenant or with entities which are
otherwise Affiliates of Tenant), then Tenant’s obligation to provide Landlord with a copies of its
financial statements shall be deemed satisfied. Failure of Tenant to timely execute, acknowledge
and deliver such estoppel certificate or other instruments shall constitute an acceptance of the
Premises and an acknowledgment by Tenant that statements included in the estoppel certificate are
true and correct, without exception.

ARTICLE 18

SUBORDINATION

     This Lease shall be subject and subordinate to all present and future ground or underlying
leases of the Building or Project and to the lien of any mortgage, trust deed or other encumbrances
now or hereafter in force against the Building or Project or any part thereof, if any, and to all
renewals, extensions, modifications, consolidations and replacements thereof, and to all advances
made or hereafter to be made upon the security of such mortgages or trust deeds, unless the holders
of such mortgages, trust deeds or other encumbrances, or the lessors under such ground lease or
underlying leases, require in writing that this Lease be superior thereto (collectively, the
"Superior Holders”); provided, however, that in consideration of and a condition precedent to
Tenant’s agreement to subordinate this Lease, shall be the receipt by Tenant of a non-disturbance
agreement in the Superior Holders’ standard form, provided that such standard form shall (i)
require such Superior Holder to accept this Lease, and not to disturb Tenant’s possession, so long
as Tenant is not in default under the terms of this Lease beyond any applicable notice and cure
period, and (ii) not materially increase Tenant’s
obligations under this Lease (a “SNDAA”). Landlord shall use commercially reasonable efforts
to deliver to Tenant a SNDAA from any current Superior Holder on or before the Lease Commencement
Date. Tenant covenants and agrees in the event any proceedings are brought for the foreclosure of
any such mortgage or deed in lieu thereof (or if any ground lease is terminated), to attorn,
without any deductions or set-offs whatsoever, to the lienholder or purchaser or any successors
thereto upon any such foreclosure sale or deed in lieu thereof (or to the ground lessor), if so
requested to do so by such purchaser or lienholder or ground lessor, and to recognize such
purchaser or lienholder or ground lessor as the lessor under this Lease, provided such lienholder
or purchaser or ground

-49-

 

lessor shall agree to accept this Lease and not disturb Tenant’s occupancy,
so long as Tenant timely pays the rent and observes and performs the TCCs of this Lease to be
observed and performed by Tenant. Landlord’s interest herein may be assigned as security at any
time to any lienholder. Tenant shall, within fifteen (15) days of request by Landlord, execute a
commercially reasonable Non-Disturbance Agreement and/or other reasonable instruments or
assurances, reasonably acceptable to Tenant, as may reasonably be required to evidence or confirm
the subordination or superiority of this Lease to any such mortgages, trust deeds, ground leases or
underlying leases. Except as otherwise expressly set forth in any Non-Disturbance Agreement
entered into by Tenant and any current or future lender, ground lessor or other lienholder, Tenant
waives the provisions of any current or future statute, rule or law which may give or purport to
give Tenant any right or election to terminate or otherwise adversely affect this Lease and the
obligations of the Tenant hereunder in the event of any foreclosure proceeding or sale.

ARTICLE 19

DEFAULTS; REMEDIES

     19.1 Events of Default. The occurrence of any of the following shall constitute a
default of this Lease by Tenant:

          19.1.1 Any failure by Tenant to pay any Rent or any other charge required to be paid under
this Lease, or any part thereof, when due, which failure is not cured within three (3) business
days after written notice from Landlord that said amount was not paid when due; or

          19.1.2 Except where a specific time period is otherwise set forth for Tenant’s performance in
this Lease, in which event the failure to perform by Tenant within such time period shall be a
default by Tenant under this Section 19.1.2, any failure by Tenant to observe or perform
any other provision, covenant or condition of this Lease to be observed or performed by Tenant
where such failure continues for twenty (20) days after written notice thereof from Landlord to
Tenant; provided that if the nature of such default is such that the same cannot reasonably be
cured within a twenty (20) day period, Tenant shall not be deemed to be in default if it diligently
commences such cure within such period and thereafter diligently proceeds to rectify and cure such
default, but in no event exceeding a period of time in excess of thirty (30) days after written
notice thereof from Landlord to Tenant; or

          19.1.3 To the extent permitted by law, a general assignment by Tenant or any guarantor of this
Lease for the benefit of creditors, or the taking of any corporate action in
furtherance of bankruptcy or dissolution whether or not there exists any proceeding under an
insolvency or bankruptcy law, or the filing by or against Tenant or any guarantor of any proceeding
under an insolvency or bankruptcy law, unless in the case of a proceeding filed against Tenant or
any guarantor the same is dismissed within sixty (60) days, or the appointment of a trustee or
receiver to take possession of all or substantially all of the assets of Tenant or any guarantor,
unless possession is restored to Tenant or such guarantor within thirty (30) days, or any execution
or other judicially authorized seizure of all or substantially all of Tenant’s assets located upon
the Premises or of Tenant’s interest in this Lease, unless such seizure is discharged within thirty
(30) days; or

-50-

 

          19.1.4 Abandonment, pursuant to California Civil Code Section 1951.3, of the Premises by
Tenant; or

          19.1.5 The failure by Tenant to observe or perform according to the provisions of Articles
5, 14, 17 or 18 of this Lease where such failure continues for more than two (2) business days
after notice from Landlord.

     The notice periods provided herein are in lieu of, and not in addition to, any notice periods
provided by law.

     19.2 Remedies Upon Default. Upon the occurrence of any event of default by Tenant,
Landlord shall have, in addition to any other remedies available to Landlord at law or in equity
(all of which remedies shall be distinct, separate and cumulative), the option to pursue any one or
more of the following remedies, each and all of which shall be cumulative and nonexclusive, without
any notice or demand whatsoever.

          19.2.1 Terminate this Lease, in which event Tenant shall immediately surrender the Premises to
Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which
it may have for possession or arrearages in rent, enter upon and take possession of the Premises
and expel or remove Tenant and any other person who may be occupying the Premises or any part
thereof, without being liable for prosecution or any claim or damages therefor; and Landlord may
recover from Tenant the following:

               (a) The worth at the time of award of any unpaid rent which has been earned at the time of
such termination; plus

               (b) The worth at the time of award of the amount by which the unpaid rent which would have
been earned after termination until the time of award exceeds the amount of such rental loss that
Tenant proves could have been reasonably avoided; plus

               (c) The worth at the 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 have been reasonably avoided; plus

               (d) Any other amount necessary to compensate Landlord for all the detriment proximately caused
by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of
things would be likely to result therefrom, specifically including
but not limited to, brokerage commissions and advertising expenses incurred, expenses of
remodeling the Premises or any portion thereof for a new tenant, whether for the same or a
different use, and any special concessions made to obtain a new tenant; and

               (e) At Landlord’s election, such other amounts in addition to or in lieu of the foregoing as
may be permitted from time to time by applicable law.

     The term “rent” as used in this Section 19.2 shall be deemed to be and to mean all
sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to
Landlord or to others. As used in Sections 19.2.1(a) and (b), above, the “worth at the
time of award” shall be computed by allowing interest at the Interest Rate. As used in Section
19.2.1(c),

-51-

 

above, the “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
percent (1%).

          19.2.2 Landlord shall have the remedy described in California Civil Code Section 1951.4
(lessor may continue lease in effect after lessee’s breach and abandonment and recover rent as it
becomes due, if lessee has the right to sublet or assign, subject only to reasonable limitations).
Accordingly, if Landlord does not elect to terminate this Lease on account of any default by
Tenant, Landlord may, from time to time, without terminating this Lease, enforce all of its rights
and remedies under this Lease, including the right to recover all rent as it becomes due.

          19.2.3 Landlord shall at all times have the rights and remedies (which shall be cumulative
with each other and cumulative and in addition to those rights and remedies available under
Sections 19.2.1 and 19.2.2, above, or any law or other provision of this Lease), without
prior demand or notice except as required by applicable law, to seek any declaratory, injunctive or
other equitable relief, and specifically enforce this Lease, or restrain or enjoin a violation or
breach of any provision hereof.

     19.3 Subleases of Tenant. Whether or not Landlord elects to terminate this Lease on
account of any default by Tenant, as set forth in this Article 19, Landlord shall have the
right to terminate any and all subleases, licenses, concessions or other consensual arrangements
for possession entered into by Tenant and affecting the Premises or may, in Landlord’s sole
discretion, succeed to Tenant’s interest in such subleases, licenses, concessions or arrangements.
In the event of Landlord’s election to succeed to Tenant’s interest in any such subleases,
licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such
election, have no further right to or interest in the rent or other consideration receivable
thereunder.

     19.4 Intentionally Omitted.

     19.5 Efforts to Relet. No re-entry or repossession, repairs, maintenance, changes,
alterations and additions, reletting, appointment of a receiver to protect Landlord’s interests
hereunder, or any other action or omission by Landlord shall be construed as an election by
Landlord to terminate this Lease or Tenant’s right to possession, or to accept a surrender of the
Premises, nor shall same operate to release Tenant in whole or in part from any of Tenant’s
obligations hereunder, unless express written notice of such intention is sent by Landlord to
Tenant. Tenant hereby irrevocably waives any right otherwise available under any law to redeem or
reinstate this Lease.

     19.6 Landlord Default. Notwithstanding anything to the contrary set forth in this
Lease, Landlord shall be in default in the performance of any obligation required to be performed
by Landlord pursuant to this Lease if Landlord fails to perform such obligation within thirty (30)
days after the receipt of notice from Tenant specifying in detail Landlord’s failure to perform;
provided, however, if the nature of Landlord’s obligation is such that more than thirty (30) days
are required for its performance, then Landlord shall not be in default under this Lease if it
shall commence such performance within such thirty (30) day period and thereafter diligently
pursues the same to completion. Upon any such default by Landlord under this Lease, Tenant may,

-52-

 

except as otherwise specifically provided in this Lease to the contrary, exercise any of its rights
provided at law or in equity. Any award from a court or arbitrator in favor of Tenant requiring
payment by Landlord which is not paid by Landlord within the time period directed by such award,
may be offset by Tenant from Rent next due and payable under this Lease; provided, however, Tenant
may not deduct the amount of the award against more than fifty percent (50%) of Base Rent next due
and owing (until such time as the entire amount of such judgment is deducted) to the extent
following a foreclosure or a deed-in-lieu of foreclosure.

ARTICLE 20

COVENANT OF QUIET ENJOYMENT

     Landlord covenants that Tenant, on paying the Rent, charges for services and other payments
herein reserved and on keeping, observing and performing all the other TCCs, provisions and
agreements herein contained on the part of Tenant to be kept, observed and performed, shall, during
the Lease Term, peaceably and quietly have, hold and enjoy the Premises subject to the TCCs,
provisions and agreements hereof without interference by any persons lawfully claiming by or
through Landlord. The foregoing covenant is in lieu of any other covenant express or implied.

ARTICLE 21

SECURITY DEPOSIT

     Landlord and Tenant hereby acknowledge that Landlord, pursuant to the terms of the Existing
Lease, currently holds a security deposit (the “Existing Lease Security Deposit”) in the amount set
forth in Section 8 of the Summary, as security for the faithful performance by Tenant of
all of its obligations under the Existing Lease. Upon the Lease Commencement Date, the Existing
Lease Security Deposit shall become a surety deposit under the terms of this Lease (the “Security
Deposit”) as security for the faithful performance by Tenant of all of its obligations under this
Lease. If Tenant defaults with respect to any provisions of this Lease, including, but not limited
to, the provisions relating to the payment of Rent, the removal of property and the repair of
resultant damage, Landlord may, without notice to Tenant, but shall not be required to apply all or
any part of the Security Deposit for the payment of any Rent or any other sum in default and
Tenant shall, upon demand therefor, restore the Security Deposit to its original amount. Any
unapplied portion of the Security Deposit shall be returned to Tenant, or, at Landlord’s option, to
the last assignee of Tenant’s interest hereunder, within sixty (60) days following the expiration
of the Lease Term. Tenant shall not be entitled to any interest on the Security Deposit. Tenant
hereby waives the provisions of Section 1950.7 of the California Civil Code, or any successor
statute.

ARTICLE 22

ROOFTOP RIGHTS

     Tenant shall have the right to install equipment including, without limitation, cable, wiring,
HVAC, rooftop antennae, and other equipment associated with Tenant’s use of the

-53-

 

Premises on the roofs of the
Buildings (the “Rooftop Equipment”) and in the pathways, shafts, risers, raceways,
telephone closets, service areas and utility connections and entries into and through the
Buildings, servicing the business conducted by Tenant from within the Premises. Any such
installation shall be at Tenant’s sole cost and expense and shall be performed pursuant to the
terms and conditions or Article 8 of this Lease. The physical appearance and the size of
the Rooftop Equipment shall be subject to Landlord’s reasonable approval, the location of any such
installation of the Rooftop Equipment shall be designated by Tenant subject to Landlord’s
reasonable approval and Landlord may require Tenant to install screening around such Rooftop
Equipment, at Tenant’s sole cost and expense, as reasonably designated by Landlord. Tenant shall
keep all such Rooftop Equipment in good order, condition and repair, at Tenant’s sole cost and
expense. Tenant’s installation of the Rooftop Equipment shall be done in such a manner as not to
void any existing roof warranties in place at the Buildings (and Tenant shall indemnify and hold
Landlord harmless in the event any such warranties are voided as a result of the installation of
any Rooftop Equipment by Tenant). Tenant shall, at Tenant’s sole cost and expense, be responsible
to repair any damage to the Buildings, including the roof and roof membrane, caused by the
installation of any Rooftop Equipment. At the expiration or earlier termination of this Lease,
Tenant shall remove any Rooftop Equipment installed by or on behalf of Tenant and repair any damage
to the roof or roof membrane caused by the installation or removal of the Rooftop Equipment by
Tenant. Tenant shall not be entitled to license its Rooftop Equipment, or the right to install
equipment on the rooftops, to any unrelated third party (other than a Non-Transferee Assignee in
connection with a Non-Transfer), nor shall Tenant be permitted to receive any revenues, fees or any
other consideration for the use of such Rooftop Equipment by an unrelated third party. Tenant
hereby acknowledges Landlord’s continued right to itself utilize the rooftop space. The rights
contained in this Article 22 shall be personal to the Original Tenant and any Permitted
Assignee, and may only be exercised by the Original Tenant or a Permitted Assignee (and not any
other assignee, sublessee or other transferee of the Original Tenant’s interest in this Lease) if
Tenant is in occupancy of at least seventy percent (70%) of the entire Premises, provided that for
purposes of this Article 22, the Original Tenant or Permitted Assignee, as the case may be,
shall be deemed to be in occupancy of any space sublet to any Transferee pursuant to a sublease
consented to by Landlord pursuant to the terms of Article 14 of this Lease. In addition,
Landlord hereby acknowledges that following the proper exercise of Tenant’s right to install
Rooftop Equipment as set forth herein, Tenant may thereafter elect to
install such equipment on behalf of a subtenant approved by Landlord pursuant to the terms and
conditions of Article 14, below.

ARTICLE 23

SIGNS

     23.1 Full Floors. Subject to Landlord’s prior written approval, in its reasonable
discretion, and provided all signs are in keeping with the quality, design and style of the
Building and Project, Tenant, if the Premises comprise an entire floor of the Building, at its sole
cost and expense, may install identification signage anywhere in the Premises including in the
elevator lobby of the Premises, provided that such signs must not be visible from the exterior of
the Building.

-54-

 

     23.2 Multi-Tenant Floors. If other tenants occupy space on the floor on which the
Premises is located, Tenant’s identifying signage shall be provided by Landlord, at Tenant’s cost,
and such signage shall be comparable to that used by Landlord for other similar floors in the
Building and shall comply with Landlord’s Building standard signage program.

     23.3 Prohibited Signage and Other Items. Any signs, notices, logos, pictures, names
or advertisements which are installed and that have not been separately approved by Landlord may be
removed without notice by Landlord at the sole expense of Tenant. Tenant may not install any signs
on the exterior or roof of the Project or the Common Areas. Any signs, window coverings, or blinds
(even if the same are located behind the Landlord-approved window coverings for the Building), or
other items visible from the exterior of the Premises or Building, shall be subject to the prior
approval of Landlord, in its sole discretion.

     23.4 Monument and Building-Top Signage.

          23.4.1 In General. In addition to the signage rights set forth above in this
Article 23, Tenant shall be entitled to install the following signage in connection with
Tenant’s lease of the Premises (collectively, the “Tenant’s Signage”):

	 	(i)	 	In the event Landlord elects, in Landlord’s sole and absolute
discretion, to construct a Building monument sign near the main entrance to any
Building, then Tenant shall be entitled to install one (1) sign identifying
Tenant’s name and/or logo in the most prominent (i.e., top) position on such
monument sign, in connection with Tenant’s lease of the Premises; provided,
however, such right shall be subordinate to the rights to other tenant in the
Project pursuant to leases in effect as of the date of this Lease; and
	 
	 	(ii)	 	Non-exclusive Building-top signage consisting of one (1)
building-top sign identifying Tenant’s name and/or logo located at the top of
each of Building F and Building A of a side of such Building that can be seen
from Highway 101.

          23.4.2 Specifications and Permits. Tenant’s Signage shall set forth Tenant’s name and
logo as determined by Tenant in its sole discretion; provided, however, in no event shall Tenant’s
Signage include an “Objectionable Name,” as that term is defined in Section 23.4.3, below.
The graphics, materials, color, design, lettering, lighting, size, illumination, specifications and
exact location of Tenant’s Signage (collectively, the “Sign Specifications”) shall be subject to
the prior written approval of Landlord, which approval shall not be unreasonably withheld,
conditioned or delayed, and shall be consistent and compatible with the quality and nature of the
Project and Landlord Building standard signage specifications. In addition, Tenant’s Signage shall
be subject to Tenant’s receipt of all required governmental permits and approvals and shall be
subject to all applicable laws and to any covenants, conditions and restrictions affecting the
Project. In the event Tenant does not receive the necessary governmental approvals and permits for
Tenant’s Signage, Tenant’s and Landlord’s rights and obligations under the remaining terms and
conditions of the Lease shall be unaffected.

-55-

 

          23.4.3 Objectionable Name. To the extent the Original Tenant desires to change the
name and/or logo set forth on Tenant’s Signage, such name and/or logo shall not have a name which
relates to an entity which is of a character or reputation, or is associated with a political
faction or orientation, which is inconsistent with the quality of the Project, or which would
otherwise reasonably offend a landlord of the Comparable Buildings (an “Objectionable Name”). The
parties hereby agree that the name “IXIA” or any reasonable derivation thereof, shall not be deemed
an Objectionable Name.

          23.4.4 Termination of Right to Tenant’s Signage. The rights contained in this
Section 23.4 shall be personal to the Original Tenant and any Permitted Assignee, and may
only be exercised by the Original Tenant or a Permitted Assignee (and not any other assignee,
sublessee or transferee of the Original Tenant’s interest in the Lease) if Tenant is in occupancy
of at least seventy percent (70%) of the entire Premises, provided that purposes of this
Section 23.4.4, the Original Tenant or Permitted Assignee, as the case may be, shall be
deemed to be in occupancy of any space sublet to any Transferee pursuant to a sublease consented to
by Landlord pursuant to the terms of Article 14 of this Lease. In addition, Landlord
hereby acknowledges that following the proper exercise of Tenant’s signage rights as set forth
herein, Tenant may thereafter elect to install such signage on behalf of a subtenant approved by
Landlord pursuant to the terms and conditions of Article 14, below, provided such subtenant
occupies at lease seventy percent (70%) of the Premises.

          23.4.5 Cost and Maintenance. The costs of Tenant’s Signage and the installation,
design, construction and any and all other costs associated with Tenant’s Signage, including,
without limitation, utility charges and hook-up fees, permits, and maintenance and repairs, shall
be the sole responsibility of Tenant; provided however, that, at Landlord’s option, Landlord may
install Tenant’s Signage and Tenant shall pay Landlord the cost thereof, including a reasonable
amount sufficient to reimburse Landlord for all overhead, general conditions, fees and other costs
or expenses arising from the installation of Tenant’s Signage. Should Tenant’s Signage require
repairs and/or maintenance, as determined in Landlord’s reasonable judgment, Landlord shall have
the right to provide notice thereof to Tenant and Tenant (except as set forth below) shall cause
such repairs and/or maintenance to be performed within thirty (30) days after receipt of such
notice from Landlord, at Tenant’s sole cost and expense; provided, however, if
such repairs and/or maintenance are reasonably expected to require longer than thirty (30)
days to perform, Tenant shall commence such repairs and/or maintenance within such thirty (30) day
period and shall diligently prosecute such repairs and maintenance to completion. Should Tenant
fail to perform such repairs and/or maintenance within the periods described in the immediately
preceding sentence, Landlord shall, upon the delivery of an additional five (5) business days’
prior written notice, have the right to cause such work to be performed and to charge Tenant as
Additional Rent for the actual cost of such work. Upon the expiration or earlier termination of
the Lease, Tenant shall, at Tenant’s sole cost and expense, cause Tenant’s Signage to be removed
and shall cause the areas in which such Tenant’s Signage was located to be restored to the
condition existing immediately prior to the placement of such Tenant’s Signage (reasonable wear and
tear excepted). If Tenant fails to timely remove Tenant’s Signage or to restore the areas in which
such Tenant’s Signage was located, as provided in the immediately preceding sentence, then Landlord
may perform such work, and all actual costs incurred by Landlord in so performing shall be
reimbursed by Tenant to Landlord within thirty (30) days after Tenant’s receipt of an invoice
therefor. The terms and conditions of this Section 23.4.5 shall survive the

-56-

 

expiration or
earlier termination of the Lease. In the event the rooftop mechanical shielding is modified by
Landlord and, as a result Tenant’s Signage must be redesigned or relocated, then Landlord agrees
that following such redesign or relocation Tenant’s signage shall be no less prominent (vis-à-vis
other Tenant signage on the affected Building), than Tenant’s Signage prior to such redesign or
relocation.

ARTICLE 24

COMPLIANCE WITH LAW

     Tenant shall not do anything or suffer anything to be done in or about the Premises or the
Project which will in any way conflict with any law, statute, ordinance or other governmental rule,
regulation or requirement now in force or which may hereafter be enacted or promulgated
(collectively, “Applicable Laws”). At its sole cost and expense, Tenant shall promptly comply with
all such Applicable Laws which relate to (i) Tenant’s use of the Premises for non-general office
use, (ii) the Alterations or Tenant Improvements in the Premises, or (iii) the Base Building, but,
as to the Base Building, only to the extent such obligations are triggered by Tenant’s Alterations,
the Tenant Improvements, or use of the Premises for non-general office use. Should any standard or
regulation now or hereafter be imposed on Landlord or Tenant by a state, federal or local
governmental body charged with the establishment, regulation and enforcement of occupational,
health or safety standards for employers, employees, landlords or tenants, then Tenant agrees to
the extent the standard or regulation relates to Tenant’s use of the Premises, at its sole cost and
expense, to comply promptly with such standards or regulations. The judgment of any court of
competent jurisdiction or the admission of Tenant in any judicial action, regardless of whether
Landlord is a party thereto, that Tenant has violated any of said governmental measures, shall be
conclusive of that fact as between Landlord and Tenant. Landlord shall comply with all Applicable
Laws relating to the Base Building, provided that compliance with such Applicable Laws is not the
responsibility of Tenant under this Article 24, and provided further that Landlord’s failure to
comply therewith would prohibit Tenant from obtaining or maintaining a certificate of occupancy for
the Premises, or would unreasonably and materially affect the safety of Tenant’s
employees or create a significant health hazard for Tenant’s employees. Landlord shall be
permitted to include in Operating Expenses any costs or expenses incurred by Landlord under this
Article 24 to the extent consistent with the terms of Section 4.2.4, above.

ARTICLE 25

LATE CHARGES

     If any installment of Rent or any other sum due from Tenant shall not be received by Landlord
or Landlord’s designee when due, then Tenant shall pay to Landlord a late charge equal to five
percent (5%) of the overdue amount plus any attorneys’ fees incurred by Landlord by reason of
Tenant’s failure to pay Rent and/or other charges when due hereunder; provided, however, with
regard to the first such failure in any twelve (12) month period, Landlord will waive such late
charge to the extent Tenant cures such failure within three (3) days following Tenant’s receipt of
written notice from Landlord that the same was not received when due. The late charge shall be
deemed Additional Rent and the right to require it shall be in addition to all

-57-

 

of Landlord’s other
rights and remedies hereunder or at law and shall not be construed as liquidated damages or as
limiting Landlord’s remedies in any manner. In addition to the late charge described above, any
Rent or other amounts owing hereunder which are not paid within ten (10) days after the date they
are due shall bear interest from the date when due until paid at the “Interest Rate.” For purposes
of this Lease, the “Interest Rate” shall be an annual rate equal to the lesser of (i) the annual
“Bank Prime Loan” rate cited in the Federal Reserve Statistical Release Publication H.15(519),
published weekly (or such other comparable index as Landlord and Tenant shall reasonably agree upon
if such rate ceases to be published), plus two (2) percentage points, and (ii) the highest rate
permitted by applicable law.

ARTICLE 26

LANDLORD’S RIGHT TO CURE DEFAULT; PAYMENTS BY TENANT

     26.1 Landlord’s Cure. All covenants and agreements to be kept or performed by Tenant
under this Lease shall be performed by Tenant at Tenant’s sole cost and expense and without any
reduction of Rent, except to the extent, if any, otherwise expressly provided herein. If Tenant
shall fail to perform any obligation under this Lease, and such failure shall continue in excess of
the time allowed under Section 19.1.2, above, unless a specific time period is otherwise
stated in this Lease, Landlord may, but shall not be obligated to, make any such payment or perform
any such act on Tenant’s part without waiving its rights based upon any default of Tenant and
without releasing Tenant from any obligations hereunder.

     26.2 Tenant’s Reimbursement. Except as may be specifically provided to the contrary
in this Lease, Tenant shall pay to Landlord, upon delivery by Landlord to Tenant of statements
therefor: (i) sums equal to expenditures reasonably made and obligations incurred by Landlord in
connection with the remedying by Landlord of Tenant’s defaults pursuant to the provisions of
Section 26.1; (ii) sums equal to all losses, costs, liabilities, damages and expenses
referred to in Article 10 of this Lease; and (iii) sums equal to all expenditures made and
obligations incurred by Landlord in collecting or attempting to collect the Rent or in
enforcing or attempting to enforce any rights of Landlord under this Lease or pursuant to law,
including, without limitation, all legal fees and other amounts so expended. Tenant’s obligations
under this Section 26.2 shall survive the expiration or sooner termination of the Lease
Term.

ARTICLE 27

ENTRY BY LANDLORD

     Landlord reserves the right at all reasonable times (during Building Hours with respect to
items (i) and (ii) below) and upon at least twenty-four (24) hours prior notice to Tenant (except
in the case of an emergency) to enter the Premises to (i) inspect them; (ii) show the Premises to
prospective purchasers, or to current or prospective mortgagees, ground or underlying lessors or
insurers, or during the last twelve (12) months of the Lease Term, to prospective tenants; (iii)
post notices of nonresponsibility; or (iv) alter, improve or repair the Premises or the Buildings,
or for structural alterations, repairs or improvements to the Buildings or the Buildings’ systems
and equipment. Notwithstanding anything to the contrary contained in this Article 27,
Landlord may enter the Premises at any time to (A) perform services required of Landlord;

-58-

 

(B) take
possession due to any breach of this Lease in the manner provided herein; and (C) perform any
covenants of Tenant which Tenant fails to perform. Landlord may make any such entries without the
abatement of Rent, except as otherwise provided in this Lease, and may take such reasonable steps
as required to accomplish the stated purposes; provided, however, except for (x) emergencies, (y)
repairs, alterations, improvements or additions required by governmental or quasi-governmental
authorities or court order or decree, or (z) repairs which are the obligation of Tenant hereunder,
any such entry shall be performed in a manner so as not to unreasonably interfere with Tenant’s use
of the Premises and shall be performed after normal business hours if reasonably practical. With
respect to items (y) and (z) above, Landlord shall use commercially reasonable efforts to not
materially interfere with Tenant’s use of, or access to, the Premises. Tenant hereby waives any
claims for damages or for any injuries or inconvenience to or interference with Tenant’s business
and/or lost profits occasioned thereby, provided that the foregoing shall not limit Landlord’s
liability, if any, pursuant to applicable law for personal injury and property damage to the extent
caused by the gross negligence or willful misconduct of Landlord. Provided that Landlord employs
commercially reasonable efforts to minimize interference with the conduct of Tenant’s business in
connection with entries into the Premises, Tenant hereby waives any claims for any loss of
occupancy or quiet enjoyment of the Premises in connection with such entries. For each of the
above purposes, Landlord shall at all times have a key with which to unlock all the doors in the
Premises, excluding Tenant’s vaults, safes and special security areas designated in advance by
Tenant. In an emergency, Landlord shall have the right to use any means that Landlord may deem
proper to open the doors in and to the Premises. Any entry into the Premises by Landlord in the
manner hereinbefore described shall not be deemed to be a forcible or unlawful entry into, or a
detainer of, the Premises, or an actual or constructive eviction of Tenant from any portion of the
Premises. No provision of this Lease shall be construed as obligating Landlord to perform any
repairs, alterations or decorations except as otherwise expressly agreed to be performed by
Landlord herein.

ARTICLE 28

TENANT PARKING

     28.1 General. Commencing on the Lease Commencement Date, Tenant shall have the right
to use the amount of parking passes set forth in Section 9 of the Summary, on a monthly
basis throughout the Lease Term, which parking passes shall pertain to the Project parking
facilities (both surface and covered parking facilities). Such use shall be free of charge during
the Lease Term (including the Option Term, if applicable). Notwithstanding the immediately
preceding sentence, Tenant shall be responsible for the full amount of any taxes imposed by any
governmental authority in connection with the renting of such parking passes by Tenant or the use
of the Project parking facilities by Tenant. Tenant’s continued right to use the parking passes is
conditioned upon Tenant abiding by all rules and regulations which are prescribed from time to time
for the orderly operation and use of the parking facilities where the parking passes are located,
including any sticker or other identification system established by Landlord, Tenant’s cooperation
in seeing that Tenant’s employees and visitors also comply with such rules and regulations and
Tenant not being in default under this Lease. Landlord specifically reserves the right to change
the size, configuration, design, layout and all other aspects of the Project parking facilities at
any time and Tenant acknowledges and agrees that Landlord may, without incurring any liability to
Tenant and without any abatement of Rent under this Lease, from time to time,

-59-

 

temporarily close-off
or restrict access to the Project parking facilities for purposes of permitting or facilitating any
such construction, alteration or improvements. Landlord may delegate its responsibilities
hereunder to a parking operator in which case such parking operator shall have all the rights of
control attributed hereby to the Landlord. The parking passes allocated to Tenant pursuant to this
Article 28 are provided to Tenant solely for use by Tenant’s own personnel and such passes
may not be transferred, assigned, subleased or otherwise alienated by Tenant separate from Tenant’s
interest in the Premises without Landlord’s prior approval. Tenant may validate visitor parking by
such method or methods as the Landlord may establish, at the validation rate from time to time
generally applicable to visitor parking. In the event Tenant rents from Landlord more parking
passes or reserved parking spaces than set forth in Section 9 of the Summary (other than
pursuant to Section 28.2, below), then Tenant shall pay to Landlord for such parking passes
or parking spaces, as applicable, on a monthly basis the prevailing rate charged by Landlord from
time to time at the location of such parking passes and/or spaces, as applicable.

     28.2 Parking Right of First Refusal. In addition to the rights set forth in
Section 28.1, above, Tenant shall have a right of first refusal (a “Parking ROFO”) with
respect to any reserved parking spaces located in the Building F Parking Garage that become
available for rent to third parties during the Lease Term. Landlord shall notify Tenant from
time-to-time when and if Landlord receives a bone fide third-party offer (i.e., an offer that
Landlord would be willing to accept) to rent reserved parking spaces in the Building F Parking
Garage. Pursuant to such Parking ROFO, Landlord shall offer to lease to Tenant the applicable
reserved parking spaces at the same rent as set forth in such bone fide third-party offer. If
Tenant wishes to exercise Tenant’s Parking ROFO with respect to such reserved parking spaces, then
within three (3) business days of delivery of such notice to Tenant, Tenant shall deliver notice to
Landlord of Tenant’s exercise of its Parking ROFO with respect to all of the reserved spaces
described in
Landlord’s notice to Tenant at the rent set forth in such notice. The rights contained in
this Section 28.2 shall be exercisable only so long as the Tenant occupies at least seventy
percent (70%) of the entire Premises, provided that purposes of this Section 28.2, the
Tenant shall be deemed to be in occupancy of any space sublet to any Transferee pursuant to a
sublease consented to by Landlord pursuant to the terms of Article 14 of this Lease. In
addition, Landlord hereby acknowledges that following the proper exercise of Tenant’s Parking ROFO
as set forth herein, Tenant may thereafter elect to allow a subtenant approved by Landlord pursuant
to the terms and conditions of Article 14, below, to use such reserved parking spaces.
Tenant shall not have the right to exercise its Parking ROFO if Tenant is then in default under
this Lease.

ARTICLE 29

MISCELLANEOUS PROVISIONS

     29.1 Terms; Captions. The words “Landlord” and “Tenant” as used herein shall include
the plural as well as the singular. The necessary grammatical changes required to make the
provisions hereof apply either to corporations or partnerships or individuals, men or women, as the
case may require, shall in all cases be assumed as though in each case fully expressed. The
captions of Articles and Sections are for convenience only and shall not be deemed to limit,
construe, affect or alter the meaning of such Articles and Sections.

-60-

 

     29.2 Binding Effect. Subject to all other provisions of this Lease, each of the
covenants, conditions and provisions of this Lease shall extend to and shall, as the case may
require, bind or inure to the benefit not only of Landlord and of Tenant, but also of their
respective heirs, personal representatives, successors or assigns, provided this clause shall not
permit any assignment by Tenant contrary to the provisions of Article 14 of this Lease.

     29.3 No Air Rights. No rights to any view or to light or air over any property,
whether belonging to Landlord or any other person, are granted to Tenant by this Lease. If at any
time any windows of the Premises are temporarily darkened or the light or view therefrom is
obstructed by reason of any repairs, improvements, maintenance or cleaning in or about the
Project, the same shall be without liability to Landlord and without any reduction or diminution of
Tenant’s obligations under this Lease.

     29.4 Modification of Lease. Should any current or prospective mortgagee or ground
lessor for the Building or Project require a modification of this Lease, which modification will
not cause an increased cost or expense to Tenant or in any other way materially and adversely
change the rights and obligations of Tenant hereunder, then and in such event, Tenant agrees that
this Lease may be so modified and agrees to execute whatever documents are reasonably required
therefor and to deliver the same to Landlord within ten (10) days following a request therefor. At
the request of Landlord or any mortgagee or ground lessor, Tenant agrees to execute a short form of
Lease and deliver the same to Landlord within ten (10) days following the request therefor.

     29.5 Transfer of Landlord’s Interest. Tenant acknowledges that Landlord has the right
to transfer all or any portion of its interest in the Project or Buildings and in this Lease, and
Tenant agrees that in the event of any such transfer, Landlord shall automatically be released
from all liability under this Lease and Tenant agrees to look solely to such transferee for the
performance of Landlord’s obligations hereunder after the date of transfer provided such transferee
shall have fully assumed and become liable for all obligations of this Lease to be performed by
Landlord, including the return of any Security Deposit, and Tenant shall attorn to such transferee.
Tenant further acknowledges that Landlord may assign its interest in this Lease to a mortgage
lender as additional security and agrees that such an assignment shall not release Landlord from
its obligations hereunder and that Tenant shall continue to look to Landlord for the performance of
its obligations hereunder.

     29.6 Prohibition Against Recording. Except as provided in Section 29.4 of
this Lease, neither this Lease, nor any memorandum, affidavit or other writing with respect
thereto, shall be recorded by Tenant or by anyone acting through, under or on behalf of Tenant.

     29.7 Landlord’s Title. Landlord’s title is and always shall be paramount to the title
of Tenant. Nothing herein contained shall empower Tenant to do any act which can, shall or may
encumber the title of Landlord.

     29.8 Relationship of Parties. Nothing contained in this Lease shall be deemed or
construed by the parties hereto or by any third party to create the relationship of principal and
agent, partnership, joint venturer or any association between Landlord and Tenant.

-61-

 

     29.9 Application of Payments. Landlord shall have the right to apply payments
received from Tenant pursuant to this Lease, regardless of Tenant’s designation of such payments,
to satisfy any obligations of Tenant hereunder, in such order and amounts as Landlord, in its sole
discretion, may elect.

     29.10 Time of Essence. Time is of the essence with respect to the performance of
every provision of this Lease in which time of performance is a factor.

     29.11 Partial Invalidity. If any term, provision or condition contained in this Lease
shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application
of such term, provision or condition to persons or circumstances other than those with respect to
which it is invalid or unenforceable, shall not be affected thereby, and each and every other term,
provision and condition of this Lease shall be valid and enforceable to the fullest extent possible
permitted by law.

     29.12 No Warranty. In executing and delivering this Lease, Tenant has not relied on
any representations, including, but not limited to, any representation as to the amount of any item
comprising Additional Rent or the amount of the Additional Rent in the aggregate or that Landlord
is furnishing the same services to other tenants, at all, on the same level or on the same basis,
or any warranty or any statement of Landlord which is not set forth herein or in one or more of the
exhibits attached hereto.

     29.13 Exculpation. The liability of Landlord or the Landlord Parties to Tenant for
any default by Landlord under this Lease or arising in connection herewith or with Landlord’s
operation, management, leasing, repair, renovation, alteration or any other matter relating to the
Project or the Premises shall be limited solely and exclusively to an amount which is equal to
the lesser of (a) the interest of Landlord in the Buildings or (b) the equity interest Landlord
would have in the Buildings if the Buildings were encumbered by third-party debt in an amount equal
to eighty percent (80%) of the value of the Buildings (as such value is determined by Landlord),
provided that in no event shall such liability extend to any sales or insurance proceeds received
by Landlord or the Landlord Parties in connection with the Project, Buildings or Premises. Neither
Landlord, nor any of the Landlord Parties shall have any personal liability therefor, and Tenant
hereby expressly waives and releases such personal liability on behalf of itself and all persons
claiming by, through or under Tenant. The limitations of liability contained in this Section
29.13 shall inure to the benefit of Landlord’s and the Landlord Parties’ present and future
partners, beneficiaries, officers, directors, trustees, shareholders, agents and employees, and
their respective partners, heirs, successors and assigns. Under no circumstances shall any present
or future partner of Landlord (if Landlord is a partnership), or trustee or beneficiary (if
Landlord or any partner of Landlord is a trust), have any liability for the performance of
Landlord’s obligations under this Lease. Notwithstanding any contrary provision herein, neither
Landlord nor the Landlord Parties shall be liable under any circumstances for injury or damage to,
or interference with, Tenant’s business, including but not limited to, loss of profits, loss of
rents or other revenues, loss of business opportunity, loss of goodwill or loss of use, in each
case, however occurring.

     29.14 Entire Agreement. It is understood and acknowledged that there are no oral
agreements between the parties hereto affecting this Lease and this Lease constitutes the parties’

-62-

 

entire agreement with respect to the leasing of the Premises and supersedes and cancels any and all
previous negotiations, arrangements, brochures, agreements and understandings, if any, between the
parties hereto or displayed by Landlord to Tenant with respect to the subject matter thereof, and
none thereof shall be used to interpret or construe this Lease. None of the terms, covenants,
conditions or provisions of this Lease can be modified, deleted or added to except in writing
signed by the parties hereto.

     29.15 Right to Lease. Landlord reserves the absolute right to effect such other
tenancies in the Project as Landlord in the exercise of its sole business judgment shall determine
to best promote the interests of the Buildings or Project. Tenant does not rely on the fact, nor
does Landlord represent, that any specific tenant or type or number of tenants shall, during the
Lease Term, occupy any space in the Buildings or Project.

     29.16 Force Majeure. Any prevention, delay or stoppage due to strikes, lockouts,
labor disputes, acts of God, inability to obtain services, labor, or materials or reasonable
substitutes therefor, governmental actions, civil commotions, fire or other casualty, and other
causes beyond the reasonable control of the party obligated to perform, except with respect to the
obligations imposed with regard to Rent and other charges to be paid by Tenant pursuant to this
Lease and except as to Tenant’s obligations under Articles 5 and 24 of this Lease
(collectively, a “Force Majeure”), notwithstanding anything to the contrary contained in this
Lease, shall excuse the performance of such party for a period equal to any such prevention, delay
or stoppage and, therefore, if this Lease specifies a time period for performance of an obligation
of either party, that time period shall be extended by the period of any delay in such party’s
performance caused by a Force Majeure.

     29.17 Waiver of Redemption by Tenant. Tenant hereby waives, for Tenant and for all
those claiming under Tenant, any and all rights now or hereafter existing to redeem by order or
judgment of any court or by any legal process or writ, Tenant’s right of occupancy of the Premises
after any termination of this Lease.

     29.18 Notices. All notices, demands, statements, designations, approvals or other

days after the date it is posted if sent by Mail, (ii) the date the telecopy is transmitted, (iii)
the date the overnight courier delivery is made, or (iv) the date personal delivery is made or
attempted to be made. If Tenant is notified of the identity and address of Landlord’s mortgagee or
ground or underlying lessor, Tenant shall give to such mortgagee or ground or underlying lessor
written notice of any default by Landlord under the terms of this Lease by registered or certified
mail, and such mortgagee or ground or underlying lessor shall be given a reasonable opportunity to
cure such default prior to Tenant’s exercising any remedy available to Tenant. As

AN INDEPENDENT ACTION AT LAW.

     29.23 Submission of Lease. Submission of this instrument for examination or signature
by Tenant does not constitute a reservation of, option for or option to lease, and it is not
effective as a lease or otherwise until execution and delivery by both Landlord and Tenant.

obligations set forth herein, Tenant shall not be entitled to make any repairs or perform any acts
hereunder at Landlord’s expense or to any setoff of the Rent or other amounts owing hereunder
against Landlord.

     29.26 Project or Building Name and Signage. Landlord shall have the right at any time
to change the name of the Project or Buildings and to install, affix and maintain any and all signs
on the exterior and on the interior of the Project or Buildings as Landlord may, in Landlord’s sole

governmentally mandated program, Tenant shall take responsible action for the transportation
planning and management of all employees located at the Premises by working directly with Landlord,
any governmental transportation management organization or any other transportation-related
committees or entities. The foregoing shall not preclude Tenant from disputing or challenging a
particular mandate or requirement so long as any such dispute or challenge is made in compliance
with applicable law.

     29.30 Building Renovations. It is specifically understood and agreed that Landlord
has made no representation or warranty to Tenant and has no obligation and has made no promises to
alter, remodel, improve, renovate, repair or decorate the Premises, Building, or any part thereof
and that no representations respecting the condition of the Premises or the Building have been made
by Landlord to Tenant except as specifically set forth herein or in the Tenant Work Letter.
However, Tenant hereby acknowledges that Landlord is currently renovating or may during the Lease
Term renovate, improve, alter, or modify (collectively, the “Renovations”) the Project, the

scaffolding or other necessary structures in the Building, limit or eliminate access to portions of
the Project, including portions of the common areas, or perform work in the Building, which work
may create noise, dust or leave debris in the Building. Landlord shall use commercially reasonable
efforts to complete any Renovations in a manner which does not materially, adversely affect
Tenant’s use of or access to the Premises. Notwithstanding the foregoing, but subject to the terms
of Section 6.7 og this Lease, Tenant hereby agrees that such Renovations and Landlord’s actions in
connection with such Renovations shall in no way constitute a constructive eviction of Tenant nor
entitle Tenant to any abatement of Rent. Landlord shall have no responsibility or for any reason
be liable to Tenant for any direct or indirect injury to or interference with Tenant’s business
arising from the Renovations, nor shall Tenant be entitled to any compensation or damages from
Landlord for loss of the use of the whole or any part of the Premises or of Tenant’s personal
property or improvements resulting from the Renovations or Landlord’s actions in connection with
such Renovations, or for any inconvenience or annoyance occasioned by such Renovations or
Landlord’s actions.

     29.31 No Violation. Tenant hereby warrants and represents that neither its execution
of nor performance under this Lease shall cause Tenant to be in violation of any agreement,
instrument, contract, law, rule or regulation by which Tenant is bound, and Tenant shall protect,
defend, indemnify and hold Landlord harmless against any claims, demands, losses, damages,
liabilities, costs and expenses, including, without limitation, reasonable attorneys’ fees and
costs, arising from Tenant’s breach of this warranty and representation.

-66-

 

     29.32 Communications and Computer Lines. Tenant may install, maintain, replace,
remove or use any communications or computer wires and cables (collectively, the “Lines”) at the
Project in or serving the Premises, provided that (i) Tenant shall obtain Landlord’s prior written
consent, use an experienced and qualified contractor approved in writing by Landlord, and comply
with all of the other provisions of Articles 7 and 8 of this Lease, (ii) an acceptable
number of spare Lines and space for additional Lines shall be maintained for existing and future
occupants of the Project, as determined in Landlord’s reasonable opinion, (iii) the Lines therefor
(including riser cables) shall be (x) appropriately insulated to prevent excessive electromagnetic
fields or radiation, (y) surrounded by a protective conduit reasonably acceptable to Landlord, and
(z) identified in accordance with the “Identification Requirements,” as that term is set forth
hereinbelow, (iv) any new or existing Lines servicing the Premises shall comply with all applicable
governmental laws and regulations, (v) as a condition to permitting the installation of new Lines,
Tenant shall remove existing Lines located in or serving the Premises and repair any damage in
connection with such removal, and (vi) Tenant shall pay all costs in connection therewith. All
Lines shall be clearly marked with adhesive plastic labels (or plastic tags attached to such Lines
with wire) to show Tenant’s name, suite number, telephone number and the name of the person to
contact in the case of an emergency (A) every four feet (4’) outside the Premises (specifically
including, but not limited to, the electrical room risers and other Common Areas), and (B) at the
Lines’ termination point(s) (collectively, the “Identification Requirements”). Landlord
reserves the right to require that Tenant remove any Lines located in or serving the Premises which
are installed in violation of these provisions, or which are at any time (1) are in violation of
any Applicable Laws, (2) are inconsistent with then-existing industry standards (such as the
standards promulgated by the National Fire Protection Association (e.g., such organization’s “2002
National Electrical Code”)), or (3) otherwise represent a dangerous or potentially dangerous
condition.

     29.33 Hazardous Substances.

          29.33.1 Definitions. For purposes of this Lease, the following definitions shall
apply: “Hazardous Material(s)” shall mean any solid, liquid or gaseous substance or material that
is described or characterized as a toxic or hazardous substance, waste, material, pollutant,
contaminant or infectious waste, or any matter that in certain specified quantities would be
injurious to the public health or welfare, or words of similar import, in any of the “Environmental
Laws,” as that term is defined below, or any other words which are intended to define, list or
classify substances by reason of deleterious properties such as ignitability, corrosivity,
reactivity, carcinogenicity, toxicity or reproductive toxicity and includes, without limitation,
asbestos, petroleum (including crude oil or any fraction thereof, natural gas, natural gas liquids,
liquefied natural gas, or synthetic gas usable for fuel, or any mixture thereof), petroleum
products, polychlorinated biphenyls, urea formaldehyde, radon gas, nuclear or radioactive matter,
medical waste, soot, vapors, fumes, acids, alkalis, chemicals, microbial matters (such as molds,
fungi or other bacterial matters), biological agents and chemicals which may cause adverse health
effects, including but not limited to, cancers and /or toxicity. “Environmental Laws” shall mean
any and all federal, state, local or quasi-governmental laws (whether under common law, statute or
otherwise), ordinances, decrees, codes, rulings, awards, rules, regulations or guidance or policy
documents now or hereafter enacted or promulgated and as amended from time to time, in any way
relating to a) the protection of the environment, the health and safety of persons (including
employees), property or the public welfare from actual or

-67-

 

potential release, discharge, escape or emission
(whether past or present) of any Hazardous Materials or b) the manufacture, processing,
distribution, use, treatment, storage, disposal, transport or handling of any Hazardous Materials.

          29.33.2 Compliance with Environmental Laws. Landlord covenants that during the Lease
Term, Landlord shall comply with all Environmental Laws in accordance with, and as required by, the
TCCs of Article 24 of this Lease. Tenant represents and warrants that, except as herein
set forth, it will not use, store or dispose of any Hazardous Materials in or on the Premises.
However, notwithstanding the preceding sentence, Landlord agrees that Tenant may use, store and
properly dispose of commonly available household cleaners and chemicals to maintain the Premises
and Tenant’s routine office operations (such as printer toner and copier toner) (hereinafter the
“Permitted Chemicals”). Landlord and Tenant acknowledge that any or all of the Permitted Chemicals
described in this paragraph may constitute Hazardous Materials. However, Tenant may use, store and
dispose of same, provided that in doing so, Tenant fully complies with all Environmental Laws.

          29.33.3 Landlord’s Right of Environmental Audit. Landlord may, upon reasonable notice
to Tenant, be granted access to and enter the Premises no more than once annually to perform or
cause to have performed an environmental inspection, site assessment or audit. Such environmental
inspector or auditor may be chosen by Landlord, in its sole discretion, and be performed at
Landlord’s sole expense. To the extent that the report prepared upon such inspection, assessment
or audit, indicates the presence of Hazardous Materials in violation of Environmental Laws, or
provides recommendations or suggestions to prohibit the release, discharge, escape or emission of
any Hazardous Materials at, upon, under or within the Premises, or to comply with any Environmental
Laws, Tenant shall promptly, at Tenant’s sole expense, comply with such recommendations or
suggestions, including, but not limited to performing such additional investigative or subsurface
investigations or remediation(s) as recommended by such inspector or auditor. Notwithstanding the
above, if at any time, Landlord has actual notice or reasonable cause to believe that Tenant has
violated, or permitted any violations of any Environmental Law, then Landlord will be entitled to
perform its environmental inspection, assessment or audit at any reasonable time, notwithstanding
the above mentioned annual limitation, and, if such audit reveals that Tenant has violated the
terms of this Section 29.33, Tenant must reimburse Landlord for the cost or fees incurred for such
as Additional Rent.

          29.33.4 Representations and Indemnifications. Tenant agrees to indemnify, defend,
protect and hold harmless the Landlord Parties from and against any liability, obligation, damage
or costs, including without limitation, attorneys’ fees and costs, resulting directly or indirectly
from any use, presence, removal or disposal of any Hazardous Materials or breach of any provision
of this section, to the extent such liability, obligation, damage or costs was a result of actions
caused or permitted by Tenant or a Tenant Party.

     29.34 Development of the Project.

          29.34.1 Subdivision. Landlord reserves the right to further subdivide all or a
portion of the Project, provided that no such subdivision shall have a material adverse affect on
Tenant’s use of or access to the Premises, or increase Tenant’s obligations or costs of operation
at the Premises. Tenant agrees to execute and deliver, upon demand by
Landlord and

-68-

 

in the form requested by Landlord, any additional documents needed to conform
this Lease to the circumstances resulting from such subdivision.

          29.34.2 The Other Improvements. If portions of the Project or property adjacent to
the Project (collectively, the “Other Improvements”) are owned by an entity other than Landlord,
Landlord, at its option, may enter into an agreement with the owner or owners of any or all of the
Other Improvements to provide (i) for reciprocal rights of access and/or use of the Project and the
Other Improvements, (ii) for the common management, operation, maintenance, improvement and/or
repair of all or any portion of the Project and the Other Improvements, (iii) for the allocation of
a portion of the Direct Expenses to the Other Improvements and the operating expenses and taxes for
the Other Improvements to the Project, and (iv) for the use or improvement of the Other
Improvements and/or the Project in connection with the improvement, construction, and/or excavation
of the Other Improvements and/or the Project, provided that no such reciprocal easement agreements
shall in any way (A) reduce the number of parking passes to which Tenant is entitled, or (B)
relieve Landlord of its obligations under the Parking ROFO. Nothing contained herein shall be
deemed or construed to limit or otherwise affect Landlord’s right to convey all or any portion of
the Project or any other of Landlord’s rights described in this Lease.

          29.34.3 Construction of Project and Other Improvements. Tenant acknowledges that
portions of the Project and/or the Other Improvements may be under construction following Tenant’s
occupancy of the Premises, and that such construction may result in levels of noise, dust,
obstruction of access, etc. which are in excess of that present in a fully constructed project.
Tenant hereby waives any and all rent offsets (except as specifically set forth in Section
6.7 of this Lease) in connection with such construction. Furthermore, provided that Landlord
employs commercially reasonable efforts to minimize interference with the conduct of Tenant’s
business, Tenant hereby waives any claims of constructive eviction which may arise in connection
with such construction.

     29.35 Bifurcation of Lease. Landlord shall have the right, if reasonably deemed
necessary by Landlord, at any time during the Lease Term, to cause this Lease to be amended and
replaced by three (3) separate leases, one with respect to portions of the Premises located in
Building F, one with respect to portions of the Premises located in Building A, and one with
respect to portions of the Premises located in Building C. Provided that such bifurcation does not
increase Tenant’s obligations hereunder on a net basis, or otherwise materially affect Tenant’s use
and occupancy of the Premises as provided for by the terms of this Lease, Tenant shall use
cooperate with Landlord in connection with any such bifurcation of this Lease.

improvement of the Premises for Tenant. This Tenant Work Letter is essentially organized
chronologically and addresses the issues of construction, in sequence, as such issues will arise
during the actual construction of the initial improvement of the Premises. All references in this
Tenant Work Letter to Articles or Sections of “this Lease” shall mean the relevant portions of
Articles 1 through 29 of the Office Lease to which this Tenant Work Letter is
attached as Exhibit B, and all references in this Tenant Work Letter to Sections of “this
Tenant Work Letter” shall mean the relevant portions of Sections 1 through 5 of
this Tenant Work Letter.

SECTION 1

DELIVERY OF THE PREMISES AND BASE BUILDING

     1.1 Base Building. Upon the full execution and delivery of this Lease by Landlord and
Tenant, Landlord shall deliver the Premises and “Base Building,” as that term is defined in
Section 7 of this Lease, to Tenant, and Tenant shall accept the Premises and Base Building

particularly set forth in Section 8.5 of this Lease, all Tenant Improvements

EXHIBIT B
-1-

 

 

for which the Tenant Improvement Allowance has been made available shall be deemed Landlord’s
property under the terms of the Lease. Tenant hereby acknowledges and agrees that any unused
portion of the Tenant Improvement Allowance remaining as of December 31, 2008, shall revert to
Landlord and Tenant shall have no further right thereto; provided, however, Tenant may, by
delivering written notice to Landlord anytime after Landlord’s disbursement of the “Final
Retention” pursuant to the terms of Section 2.2.2.2 of this Tenant Work Letter, below, but
before the date which occurs ninety (90) days following Landlord’s disbursement of such Final
Retention, elect to use up to $430,714.88 of any then remaining and unapplied portion of the Tenant
Improvement Allowance as a credit against Base Rent due with respect to the Premises under the
terms of the Lease. In addition to the Tenant Improvement Allowance, Landlord shall contribute an
amount not to exceed $9,695.52 (i.e., $0.12 per usable square foot of the Premises multiplied by
80,796 usable square feet) (“Landlord’s Drawing Contribution”) toward the cost of one (1)
preliminary space plan to be prepared by Tenant’s architect, and no portion of the Landlord’s
Drawing Contribution, if any, remaining after the completion of the Initial Installations shall be
available for use by Tenant.

      2.2 Disbursement of the Tenant Improvement Allowance.

          2.2.1 Tenant Improvement Allowance Items. Except as otherwise set forth in this
Tenant Work Letter, the Tenant Improvement Allowance shall be disbursed by Landlord only for the

the contrary contained in this Tenant Work Letter, not exceed an aggregate amount equal to $3.50
per rentable square foot of the Premises, and payment of the fees incurred by, and the cost of

Construction Drawings (including if such changes are due to the fact that such work is prepared on
an unoccupied basis), such cost to include all direct architectural and/or engineering fees and
expenses incurred in connection therewith;

               2.2.1.5 The cost of any changes to the Construction Drawings or Tenant Improvements required
by all applicable building codes (the “Code”);

               2.2.1.6 Sales and use taxes; and

          2.2.2 Disbursement of Tenant Improvement Allowance. During the construction of the
Tenant Improvements, Landlord shall make monthly disbursements of the Tenant Improvement Allowance
for Tenant Improvement Allowance Items for the benefit of Tenant and shall authorize the release of
monies for the benefit of Tenant as follows.

               2.2.2.1 Monthly Disbursements. On or before the day of each calendar month, as
determined by Landlord, during the construction of the Tenant Improvements (or such other date as
Landlord may designate), Tenant shall deliver to Landlord: (i) a request for payment of the
“Contractor,” as that term is defined in Section 4.1.1 of this Tenant Work Letter, approved
by Tenant, in a form to be provided by Landlord, showing the schedule, by trade, of percentage of
completion of the Tenant Improvements in the Premises, detailing the portion of the work completed
and the portion not completed; (ii) invoices from all of “Tenant’s Agents,” as that term is defined
in Section 4.1.2 of this Tenant Work Letter, for labor rendered and materials delivered to
the Premises; (iii) executed mechanic’s lien releases from all of Tenant’s Agents which shall
comply with the appropriate provisions, as reasonably determined by Landlord, of California Civil
Code Section 3262(d); and (iv) all other information reasonably requested by Landlord. Tenant’s
request for payment shall be deemed Tenant’s acceptance and approval of the work furnished and/or
the materials supplied as set forth in Tenant’s payment request. Thereafter, Landlord shall
deliver a check to Tenant made jointly payable to Contractor and Tenant in payment of the lesser
of: (A) the amounts so requested by Tenant, as set forth in this Section 2.2.2.1, above,
less a ten percent (10%) retention (the aggregate amount of such retentions to be known as the
“Final Retention”), and (B) the balance of any remaining available portion of the Tenant
Improvement Allowance (not including the Final Retention), provided that Landlord does not dispute
any request for payment based on non-compliance of any work with the “Approved Working Drawings,”
as that term is defined in Section 3.4 below, or due to any substandard work, or for any
other reason. Landlord’s payment of such amounts shall not be deemed Landlord’s approval or
acceptance of the work furnished or materials supplied as set forth in Tenant’s payment request.

               2.2.2.2 Final Retention. Subject to the provisions of this Tenant Work Letter, a
check for the Final Retention payable jointly to Tenant and Contractor shall be delivered by
Landlord to Tenant following the completion of construction of the Tenant Improvements, provided
that (i) Tenant delivers to Landlord properly executed mechanic’s lien releases in compliance with
both California Civil Code Section 3262(d)(2) and either Section 3262(d)(3) or Section 3262(d)(4)
from all of Tenant’s Agents, (ii) Landlord has determined that no substandard work exists which
adversely affects the mechanical, electrical, plumbing, heating, ventilating and air conditioning,
life-safety or other systems of the Building, the curtain wall of the Building, the structure or
exterior appearance of the Building, or any other tenant’s use of such other tenant’s leased
premises in the Building, (iii) Architect delivers to Landlord a certificate, in a form reasonably
acceptable to Landlord, certifying that the construction of the Tenant Improvements in the Premises
has been substantially completed, (iv) Tenant records a valid Notice of Completion in accordance
with the requirements of Section 4.3 of this Tenant Work Letter, and (v) a certificate of
occupancy (or its equivalent) has been issued for the Premises.

               2.2.2.3 Other Terms. Landlord shall only be obligated to make disbursements from the
Tenant Improvement Allowance to the extent costs are incurred by Tenant for Tenant Improvement
Allowance Items. All Tenant Improvement Allowance Items

EXHIBIT B
-3-

 

 

for which the Tenant Improvement Allowance has been made available shall be deemed Landlord’s
property under the terms of this Lease.

     2.3 Building Standards. Landlord has established or may establish specifications for
certain Building standard components to be used in the construction of the Tenant Improvements in
the Premises, which are attached hereto as Schedule 1 (the “Building Standards”). The
quality of Tenant Improvements shall be equal to or of greater quality than the quality of such
Building Standards, provided that Landlord may, upon written notice to Tenant, at Landlord’s
option, require the Tenant Improvements to comply with certain Building Standards, except to the
extent that (i) such compliance would create inconsistent aesthetic effect with the existing tenant
improvements installed in the Premises (e.g., maple doors are currently installed throughout the
Premises), and (ii) the use of a different brand of materials would not compromise the quality of
the Tenant Improvements. Landlord may make changes to said specifications for Building Standards
from time to time.

     2.4 Removal of Above-Standard Tenant Improvements. “Above Standard Tenant
Improvements” shall mean (i) any part of the Tenant Improvements which are not consistent with the
Building Standards; (ii) any changes in or additions to the Tenant Improvements made at the request
of Tenant or due to any other act or omission on the part of Tenant; and (iii) a configuration of
the Tenant Improvements which is not usual and customary for normal, general office occupancy. If
so directed by Landlord at the time Landlord approves the Final Space Plan and/or Final Working
Drawings, Tenant shall, at its sole cost and expense, prior to the expiration or earlier
termination of the Lease Term, remove from the Premises any Above Standard Tenant Improvements
designated by Landlord, and shall replace such designated Above Standard Tenant Improvements to be
removed with Building standard improvements. Such removal and replacement of Above Standard Tenant
Improvements shall be performed promptly and shall be completed by Tenant on or before the later of
(x) the expiration of the Lease Term, or (y) the date which is thirty (30) days following
Landlord’s delivery of written notice to Tenant regarding such removal obligation, and if Tenant
fails to timely remove and/or replace any such identified Above Standard Tenant Improvements, then
at Landlord’s option, either (1) Tenant shall be deemed to be holding over in the Premises and Rent
shall continue to accrue in accordance with the terms of Article 16 of this Lease, until
such work shall be completed, or (2) Landlord may do so and may charge the cost thereof to Tenant,
in which event Tenant shall be deemed to be holding over in the Premises, and Rent shall continue
to accrue in accordance with the terms of Article 16 of this Lease, until the earlier of (A) the
date Landlord completes such work, or (B) the reasonably anticipated date for such completion
assuming Landlord’s use of commercially reasonable and diligent efforts in completing the same.

SECTION 3

CONSTRUCTION DRAWINGS

     3.1 Selection of Architect/Construction Drawings. Tenant shall retain an
architect/space planner designated by Tenant and reasonably approved in advance by Landlord (the
“Architect”) to prepare the “Construction Drawings,” as that term is defined in this Section
3.1. Tenant shall retain engineering consultants designated by Tenant and reasonably approved
in advance by Landlord (the “Engineers”) to prepare all plans and engineering working drawings
relating to the structural, mechanical, electrical, plumbing, HVAC, life safety, and sprinkler work

EXHIBIT B
-4-

 

 

in the Premises, which work is not part of the Base Building. The plans and drawings to be
prepared by Architect and the Engineers hereunder shall be known collectively as the “Construction
Drawings.” All Construction Drawings shall comply with the drawing format and specifications
determined by Landlord, and shall be subject to Landlord’s approval. Tenant and Architect shall
verify, in the field, the dimensions and conditions as shown on the relevant portions of the Base
Building plans, and Tenant and Architect shall be solely responsible for the same, and Landlord
shall have no responsibility in connection therewith. Landlord’s review of the Construction
Drawings as set forth in this Section 3, shall be for its sole purpose and shall not imply
Landlord’s review of the same, or obligate Landlord to review the same, for quality, design, Code
compliance or other like matters. Accordingly, notwithstanding that any Construction Drawings are
reviewed by Landlord or its space planner, architect, engineers and consultants, and
notwithstanding any advice or assistance which may be rendered to Tenant by Landlord or Landlord’s
space planner, architect, engineers, and consultants, Landlord shall have no liability whatsoever
in connection therewith and shall not be responsible for any omissions or errors contained in the
Construction Drawings, and Tenant’s waiver and indemnity set forth in this Lease shall specifically
apply to the Construction Drawings.

     3.2 Final Space Plan. Tenant shall supply Landlord with four (4) copies signed by
Tenant of its final space plan for the Premises before any architectural working drawings or
engineering drawings have been commenced. In addition, Tenant shall supply Landlord with a copy of
the final space plan in an AutoCAD Computer Assisted Drafting and Design System format. The final
space plan (the “Final Space Plan”) shall include a layout and designation of all offices, rooms
and other partitioning, their intended use, and equipment to be contained therein. Landlord may
request clarification or more specific drawings for special use items not included in the Final
Space Plan. Landlord shall advise Tenant within five (5) business days after Landlord’s receipt of
the Final Space Plan for the Premises if the same is unsatisfactory or incomplete in any respect.
If Tenant is so advised, Tenant shall promptly cause the Final Space Plan to be revised to correct
any deficiencies or other matters Landlord may reasonably require.

     3.3 Final Working Drawings. After the Final Space Plan has been approved by Landlord,
Tenant shall supply the Engineers with a complete listing of standard and non-standard equipment
and specifications, including, without limitation, B.T.U. calculations, electrical requirements and
special electrical receptacle requirements for the Premises, to enable the Engineers and the
Architect to complete the “Final Working Drawings” (as that term is defined below) in the manner as
set forth below. Upon the approval of the Final Space Plan by Landlord and Tenant, Tenant shall
promptly cause the Architect and the Engineers to complete the architectural and engineering
drawings for the Premises, and Architect shall compile a fully coordinated set of architectural,
structural, mechanical, electrical and plumbing working drawings in a form which is complete to
allow all of Tenant’s Agents to bid on the work and to obtain all applicable permits (collectively,
the “Final Working Drawings”) and shall submit the same to Landlord for Landlord’s approval.
Tenant shall supply Landlord with four (4) copies signed by Tenant of such Final Working Drawings,
including one (1) copy in an AutoCAD Computer Assisted Drafting and Design System format. Landlord
shall advise Tenant within ten (10) business days after Landlord’s receipt of the Final Working
Drawings for the Premises if the same is unsatisfactory or incomplete in any respect. If Tenant is
so advised, Tenant shall immediately revise the Final Working Drawings in accordance with such
review and any disapproval of Landlord in connection therewith. In addition, if the Final Working
Drawings or any amendment thereof or supplement thereto shall require alterations in the Base
Building (as

EXHIBIT B
-5-

 

 

contrasted with the Tenant Improvements), and if Landlord in its sole and exclusive discretion
agrees to any such alterations, and notifies Tenant of the need and cost for such alterations, then
Tenant shall pay the cost of such required changes in advance upon receipt of notice thereof.
Tenant shall pay all direct architectural and/or engineering fees in connection therewith, plus
fifteen percent (15%) of such direct costs for Landlord’s servicing and overhead.

     3.4 Approved Working Drawings. The Final Working Drawings shall be approved by
Landlord (the “Approved Working Drawings”) prior to the commencement of construction of the
Premises by Tenant. After approval by Landlord of the Final Working Drawings, Tenant may submit
the same to the appropriate municipal authorities for all applicable building permits. Tenant
hereby agrees that neither Landlord nor Landlord’s consultants shall be responsible for obtaining
any building permit or certificate of occupancy for the Premises and that obtaining the same shall
be Tenant’s responsibility; provided, however, that Landlord shall cooperate with Tenant in
executing permit applications and performing other ministerial acts reasonably necessary to enable
Tenant to obtain any such permit or certificate of occupancy. No changes, modifications or
alterations in the Approved Working Drawings may be made without the prior written consent of
Landlord which consent may not be unreasonably withheld, conditioned or delayed.

SECTION 4

CONSTRUCTION OF THE TENANT IMPROVEMENTS

     4.1 Tenant’s Selection of Contractors.

          4.1.1 The Contractor. A general contractor shall be retained by Tenant to construct
the Tenant Improvements. Such general contractor (“Contractor”) shall be selected by Tenant,
subject to Landlord’s reasonable approval.

          4.1.2 Tenant’s Agents. All subcontractors, laborers, materialmen, and suppliers used
by Tenant (such subcontractors, laborers, materialmen, and suppliers, and the Contractor to be
known collectively as “Tenant’s Agents”) must be approved in writing by Landlord, which approval
shall not be unreasonably withheld, conditioned or delayed; provided, however, Landlord may
nevertheless designate and require the use of particular mechanical, engineering, plumbing, fire
life-safety and other Base Building subcontractors. If Landlord does not approve any of Tenant’s
proposed subcontractors, laborers, materialmen or suppliers, Tenant shall submit other proposed
subcontractors, laborers, materialmen or suppliers for Landlord’s written approval.

     4.2 Construction of Tenant Improvements by Tenant’s Agents.

          4.2.1 Construction Contract; Cost Budget. Tenant shall engage the Contractor under an
AIA A101 Stipulated Sum Agreement (1997 Version) accompanied by Landlord’s standard AIA A201
General Conditions (1997 Version) as modified by Landlord (collectively, the “Contract”). Prior to
the commencement of the construction of the Tenant Improvements, and after Tenant has accepted all
bids for the Tenant Improvements, Tenant shall provide Landlord with a detailed breakdown, by
trade, of the final costs to be incurred or which have been incurred, as set forth more
particularly in Sections 2.2.1.1 through 2.2.1.7, above, in connection with the
design and construction of the Tenant Improvements to be performed by or at the direction of Tenant
or the Contractor, which costs form a basis for the amount of the

EXHIBIT B
-6-

 

 

Contract (the “Final Costs”). In the event that the Final Costs are greater than the amount
of the Tenant Improvement Allowance (the “Over-Allowance Amount”), then Tenant shall pay a
percentage of each amount requested by the Contractor or otherwise to be disbursed under this
Tenant Work Letter, which percentage shall be equal to the Over-Allowance Amount divided by the
amount of the Final Costs (after deducting from the Final Costs any amounts expended in connection
with the preparation of the Construction Drawings, and the cost of all other Tenant Improvement
Allowance Items incurred prior to the commencement of construction of the Tenant Improvements), and
such payments by Tenant (the “Over-Allowance Payments”) shall be a condition to Landlord’s
obligation to pay any amounts from the Tenant Improvement Allowance. In the event that, after the
Final Costs have been delivered by Tenant to Landlord, the costs relating to the design and
construction of the Tenant Improvements shall change, any additional costs necessary to such design
and construction in excess of the Final Costs, shall be added to the Over-Allowance Amount and the
Final Costs, and the Over-Allowance Payments shall be recalculated in accordance with the terms of
the immediately preceding sentence. In connection with any payment of the Over-Allowance Amount
made by Tenant pursuant to this Section 4.2.1, Tenant shall provide Landlord with the
documents described in Sections 2.2.2.1(i), (ii), (iii) and (iv) of
this Tenant Work Letter, above, for Landlord’s approval, prior to Tenant paying such costs.

          4.2.2 Tenant’s Agents.

following: (i) the Tenant Improvements shall be constructed in strict accordance with the Approved
Working Drawings; (ii) Tenant’s Agents shall submit schedules of all work relating to the Tenant’s
Improvements to Contractor and Contractor shall, within five (5) business days of receipt thereof,
inform Tenant’s Agents of any changes which are necessary thereto, and Tenant’s Agents shall adhere
to such corrected schedule; and (iii) Tenant shall abide by all rules made by Landlord’s Building
manager with respect to the use of freight, loading dock and service elevators, storage of
materials, coordination of work with the contractors of other tenants, and any other matter in
connection with this Tenant Work Letter, including, without limitation, the construction of the
Tenant Improvements.

               4.2.2.2 Indemnity. Tenant’s indemnity of Landlord as set forth in this Lease shall
also apply with respect to any and all costs, losses, damages, injuries and liabilities related in
any way to any act or omission of Tenant or Tenant’s Agents, or anyone directly or indirectly
employed by any of them, or in connection with Tenant’s non-payment of any amount arising out of
the Tenant Improvements and/or Tenant’s disapproval of all or any portion of any request for
payment. Such indemnity by Tenant, as set forth in this Lease, shall also apply with respect to
any and all costs, losses, damages, injuries and liabilities related in any way to Landlord’s
performance of any ministerial acts reasonably necessary (i) to permit Tenant to complete the
Tenant Improvements, and (ii) to enable Tenant to obtain any building permit or certificate of
occupancy for the Premises.

               4.2.2.3 Requirements of Tenant’s Agents. Each of Tenant’s Agents shall guarantee to
Tenant and for the benefit of Landlord that the portion of the Tenant Improvements for which it is
responsible shall be free from any defects in workmanship and materials for a period of not less
than one (1) year from the date of completion thereof. Each of Tenant’s Agents shall be
responsible for the replacement or repair, without additional charge, of all work done or

EXHIBIT B
-7-

 

 

furnished in accordance with its contract that shall become defective within one (1) year
after the later to occur of (i) completion of the work performed by such contractor or
subcontractors, and (ii) the Lease Commencement Date. The correction of such work shall include,
without additional charge, all additional expenses and damages incurred in connection with such
removal or replacement of all or any part of the Tenant Improvements, and/or the Building and/or
common areas that may be damaged or disturbed thereby. All such warranties or guarantees as to
materials or workmanship of or with respect to the Tenant Improvements shall be contained in the
Contract or subcontract and shall be written such that such guarantees or warranties shall inure to
the benefit of both Landlord and Tenant, as their respective interests may appear, and can be
directly enforced by either. Tenant covenants to give to Landlord any assignment or other
assurances which may be necessary to effect such right of direct enforcement.

               4.2.2.4 Insurance Requirements.

                    4.2.2.4.1 General Coverages. All of Tenant’s Agents shall carry worker’s
compensation insurance covering all of their respective employees, and shall also carry public
liability insurance, including property damage, all with limits, in form and with companies as are
required to be carried by Tenant as set forth in this Lease.

                    4.2.2.4.2 Special Coverages. Tenant shall, or shall cause its Contractor to, carry
“Builder’s All Risk” insurance in an amount approved by Landlord covering the construction of the
Tenant Improvements, and such other insurance as Landlord may require, it being understood and
agreed that the Tenant Improvements shall be insured by Tenant pursuant to this Lease immediately
upon completion thereof. Such insurance shall be in amounts and shall include such extended
coverage endorsements as may be reasonably required by Landlord including, but not limited to, the
requirement that all of Tenant’s Agents shall carry excess liability and Products and Completed
Operation Coverage insurance, each in amounts not less than $5,000,000 per incident, $5,000,000 in
aggregate, and in form and with companies as are required to be carried by Tenant as set forth in
this Lease.

                    4.2.2.4.3 General Terms. Certificates for all insurance carried pursuant to this
Section 4.2.2.4 shall be delivered to Landlord before the commencement of construction of
the Tenant Improvements and before any equipment of Tenant’s Agents is moved onto the site. All
such policies of insurance must contain a provision that the company writing said policy will give
Landlord thirty (30) days prior written notice of any cancellation or lapse of the effective date
or any reduction in the amounts of such insurance. In the event that the Tenant Improvements are
damaged by any cause during the course of the construction thereof, Tenant shall immediately repair
the same at Tenant’s sole cost and expense. Tenant’s Agents shall maintain all of the foregoing
insurance coverage in force until the Tenant Improvements are fully completed and accepted by
Landlord, except for Products and Completed Operations Coverage insurance required by Landlord,
which is to be maintained for ten (10) years following completion of the Tenant Improvements and
acceptance by Landlord and Tenant. All policies carried under this Section 4.2.2.4 shall
insure Landlord and Tenant, as their interests may appear, as well as Tenant’s Agents. All
insurance, except Workers’ Compensation, maintained by Tenant’s Agents shall preclude subrogation
claims by the insurer against anyone insured thereunder. Such insurance shall provide that it is
primary insurance and that any other insurance maintained by Landlord is excess and noncontributing
with the insurance required hereunder. The requirements for the foregoing insurance shall not
serve to limit the indemnification of Landlord by Tenant under Section 4.2.2.2 of this
Tenant Work Letter.

EXHIBIT B

Landlord may, in its discretion, require Tenant to obtain a lien and completion bond or some
alternate form of security satisfactory to Landlord in an amount sufficient to ensure the lien-free
completion of the Tenant Improvements and naming Landlord as a co-obligee.

          4.2.3 Governmental Compliance. The Tenant Improvements shall comply in all respects
with the following: (i) all state, federal, city or quasi-governmental laws, codes, ordinances and
regulations, as each may apply according to the rulings of the controlling public official, agent
or other person; (ii) applicable standards of the American Insurance Association (formerly, the
National Board of Fire Underwriters) and the National Electrical Code; and (iii) building material
manufacturer’s specifications.

          4.2.4 Inspection by Landlord. Landlord shall have the right to inspect the Tenant
Improvements at all times, provided however, that Landlord’s failure to inspect the Tenant
Improvements shall in no event constitute a waiver of any of Landlord’s rights hereunder nor shall
Landlord’s inspection of the Tenant Improvements constitute Landlord’s approval of the same.
Should Landlord disapprove any portion of the Tenant Improvements, Landlord shall notify Tenant in
writing of such disapproval and shall specify the items disapproved. Any defects or deviations in,
and/or disapproval by Landlord of, the Tenant Improvements shall be rectified by Tenant at no
expense to Landlord, provided however, that in the event Landlord determines that a defect or
deviation exists or disapproves of any matter in connection with any portion of the Tenant
Improvements and such defect, deviation or matter might adversely affect the mechanical,
electrical, plumbing, heating, ventilating and air conditioning or life-safety systems of the
Building, the structure or exterior appearance of the Building or any other tenant’s use of such
other tenant’s leased premises, Landlord may, take such action as Landlord deems necessary, at
Tenant’s expense and without incurring any liability on Landlord’s part, to correct any such
defect, deviation and/or matter, including, without limitation, causing the cessation of
performance of the construction of the Tenant Improvements until such time as the defect, deviation
and/or matter is corrected to Landlord’s satisfaction.

          4.2.5 Meetings. Commencing upon the approval or the Final Working Drawings, Tenant
shall hold weekly meetings at a reasonable time, with the Architect and the Contractor regarding
the progress of the preparation of Construction Drawings and the construction of the Tenant
Improvements, which meetings shall be held at a location designated by Landlord, and Landlord
and/or its agents shall receive prior notice of, and shall have the right to attend, all such
meetings, and, upon Landlord’s request, certain of Tenant’s Agents shall attend such meetings. In
addition, minutes shall be taken at all such meetings, a copy of which minutes shall be promptly
delivered to Landlord. One such meeting each month shall include the review of Contractor’s
current request for payment.

     4.3 Notice of Completion; Copy of Record Set of Plans. Within ten (10) days after
completion of construction of the Tenant Improvements, Tenant shall cause a valid Notice of
Completion to be recorded in the office of the Recorder of the county in which the Building is
located in accordance with Section 3093 of the Civil Code of the State of California or any
successor statute, and shall furnish a copy thereof to Landlord upon such recordation. If Tenant
fails to do so, Landlord may execute and file the same on behalf of Tenant as Tenant’s agent for
such purpose, at Tenant’s sole cost and expense. At the conclusion of construction, (i) Tenant
shall cause the Architect and Contractor (x) to update the Approved Working Drawings as necessary
to reflect all changes made to the Approved Working Drawings during the course of construction, (y)
to certify to the best of their knowledge that the “record-set” of as-built

EXHIBIT B

drawings are true and correct, which certification shall survive the expiration or termination
of this Lease, and (z) to deliver to Landlord two (2) sets of copies of such record set of drawings
(including one set in an AutoCAD Computer Assisted Drafting and Design System format) within ninety
(90) days following issuance of a certificate of occupancy for the Premises, and (ii) Tenant shall

Exhibit 10.1

NORTHWEST BANCORP, MHC

NORTHWEST SAVINGS BANK

AND NORTHWEST BANCORP, INC.

EMPLOYMENT AGREEMENT

FOR

WILLIAM J. WAGNER

     This Agreement is made effective as of the day 1st day of September, 2007 by and
between (i) Northwest Bancorp, MHC, a federally-chartered corporation (“MHC”), Northwest Savings
Bank (the “Bank”), a Pennsylvania-chartered stock savings bank and Northwest Bancorp, Inc., a
federally-chartered corporation (the “Company”), each with its principal administrative office at
Liberty and Second Streets, Warren, Pennsylvania 16365, (all collectively referred to as
“Employer”) and (ii) William J. Wagner (“Executive”).

     WHEREAS, the Employer and Executive entered into an employment agreement dated on July 1,
2002, pursuant to which Executive was employed as an officer of the Employer; and

     WHEREAS, Section 409A of the Internal Revenue Code (“Code”), effective January 1, 2005,
requires deferred compensation arrangements, including those set forth in employment agreements, to
comply with its provisions and restrictions and limitations on payments of deferred compensation;
and

     WHEREAS, Code Section 409A and the final regulations issued thereunder in April of 2007
necessitate changes to said employment agreement; and

     WHEREAS, Executive has agreed to such changes; and

     WHEREAS, the Employer believes it is in the best interests of the Employer to enter into a new
employment agreement (the “Agreement”) in order to reinforce and reward Executive for his service
and dedication to the continued success of the Employer and incorporate the changes required by the
new tax laws; and

     WHEREAS, the parties hereto desire to set forth the terms of the revised Agreement and the
continuing employment relationship of the Employer and Executive.

     NOW, THEREFORE, in consideration of the mutual covenants herein contained, and upon the other
terms and conditions hereinafter provided, the parties hereby agree as follows:

1. POSITION AND RESPONSIBILITIES

     During the period of his employment hereunder, Executive agrees to serve as Chairman,
President, Chief Executive Officer and a Director or Trustee of the Employer. During said period,
Executive also agrees to serve, if elected, as an officer and director of any subsidiary or
affiliate of the Employer. Failure to reelect Executive as President, Chief Executive Officer and a
Director or Trustee of the Employer, or failure to nominate Executive as a Director of the Company,
without the consent of the Executive during the term of this Agreement shall constitute a breach of
this Agreement.

 

 

2. TERMS AND DUTIES

          (a) The period of Executive’s employment under this Agreement shall begin as of the date first
above written and shall continue for a period of thirty-six (36) full calendar months thereafter.
Commencing on the first anniversary date of this Agreement, and continuing at each anniversary date
thereafter, the Agreement shall renew for an additional year such that the remaining term shall be
three (3) years unless written notice is provided to Executive at least ten (10) days and not more
than thirty (30) days prior to any such anniversary date, that this Agreement shall cease at the
end of thirty-six (36) months following such anniversary date. Prior to each notice period for
non-renewal, the Compensation Committee of the Board of Directors of the Company (the “Board”) will
induct a comprehensive performance evaluation and review of the Executive for purposes of
determining whether to extend the Agreement, and the results thereof shall be included in the
minutes of the Board’s meeting.

          (b) During the period of his employment hereunder, except for periods of absence occasioned by
illness, reasonable vacation periods, and reasonable leaves of absence, Executive shall faithfully
perform his duties hereunder, to the best of his abilities, including activities and services
related to the organization, operation and management of the Employer.

3. COMPENSATION AND REIMBURSEMENT

          (a) The compensation specified under this Agreement shall constitute the salary and benefits
paid for the duties described in Section 2(b). The Employer shall pay Executive as compensation a
salary of not less than $465,100 per year (“Base Salary”). Such Base Salary shall be payable
biweekly. During the period of this Agreement, Executive’s Base Salary shall be reviewed at least
annually. Such review shall be conducted by the Compensation Committee of the Board, and the
Compensation Committee may increase, but not decrease, Executive’s Base Salary other than pursuant
to an employer-wide reduction of compensation of all officers of the Employer and not in excess of
the average percentage of the employer-wide reduction (any increase in Base Salary shall become the
“Base Salary” for purposes of this Agreement). In addition to the Base Salary provided in this
Section 3(a), the Employer shall provide Executive with all such other benefits as are provided
uniformly to executive officers of the Employer.

          (b) The Employer will provide Executive with employee benefit plans, arrangements and
perquisites substantially equivalent to those in which Executive was participating or otherwise
deriving benefit from immediately prior to the beginning of the term of this Agreement, and the
Employer will not, without Executive’s prior written consent, make any changes to such plans,
arrangements or perquisites which would adversely affect Executive’s rights or benefits thereunder,
unless any such change is broad-based and affects substantially all executive officers of the
Employer. Without limiting the generality of the foregoing provisions of this Subsection (b),
Executive will be entitled to participate in or receive benefits under any employee benefit plans
including but not limited to the retirement plan, 401(k) plan, employee stock ownership plan,
supplemental pension plan, health-and-accident plans, medical coverage or any other employee
benefit plan or arrangement made available by the Employer in the future to its senior executives
and key management employees, subject to and on a basis consistent with the terms, conditions and
overall administration of such plans and arrangements. Executive will be entitled to incentive
compensation and bonuses as provided in any plan of the Employer in which Executive is eligible to
participate (and he shall be entitled to a pro rata distribution under any incentive compensation
or bonus plan as to any year in which a termination of employment

2

 

occurs, other than Termination for Cause). Nothing paid to the Executive under any such plan
or arrangement will be deemed to be in lieu of other compensation to which the Executive is
entitled under this Agreement.

          (c) In addition to the Base Salary provided for by paragraph (a) of this Section 3, the
Employer shall pay or reimburse Executive for all reasonable travel and other reasonable expenses
incurred by Executive performing his obligations under this Agreement and may provide such
additional compensation in such form and such amounts as the Compensation Committee may from time
to time determine.

          (d) Compensation and reimbursement to be paid pursuant to paragraphs (a), (b) and (c) of this
Section 3 shall be paid by the MHC, the Bank and the Company, respectively, on a pro rata basis,
based upon the amount of service the Executive devotes to the MHC, the Bank and Company,
respectively.

4. PAYMENTS TO EXECUTIVE UPON AN EVENT OF TERMINATION

     The provisions of this Section shall in all respects be subject to the terms and conditions
stated in Sections 7 and 14.

          (a) The provisions of this Section shall apply upon the occurrence of an Event of Termination
(as herein defined) during the Executive’s term of employment under this Agreement. As used in this
Agreement, an “Event of Termination” shall mean and include any one or more of the following:

               (i) the termination by the Employer of Executive’s full-time employment hereunder for any
reason other than (A) Disability or Retirement, as defined in Section 5 below, or (B) Termination
for Cause as defined in Section 6 hereof; or

               (ii) Executive’s resignation from the Employer’s employ, upon any

     (A) reduction in Executive’s Base Salary or a reduction in the benefits and
perquisites to the Executive from those being provided as of the effective date of
this Agreement, provided however that a reduction in benefits or perquisites that is
broad based and affects substantially all executives of the Employer shall not be
deemed an Event of Termination hereunder unless such reduction in benefits or
perquisites occurs coincident with or following a Change in Control,

     (B) failure to elect or reelect or to appoint or reappoint Executive as
Chairman, President, Chief Executive Officer and a Director or Trustee of the MHC,
the Bank, or the Company, or failure to nominate Executive as a director of the
Company, or

     (C) change in Executive’s function, duties, or responsibilities, which change
would cause Executive’s position to become one of lesser responsibility, importance,
or scope from the position and attributes thereof described in Section 1, above,

     (D) a relocation of Executive’s principal place of employment by more than 30
miles from its location as of the effective date of this Agreement, or

3

 

     (E) liquidation or dissolution of the MHC, the Bank or Company other than
liquidations or dissolutions that are caused by reorganizations that do not affect
the status of Executive, or

     (F) breach of this Agreement by the MHC, the Bank or the Company.

          Upon the occurrence of any event described in clauses (ii) (A), (B), (C), (D), (E) or (F)
above, Executive shall have the right to elect to terminate his employment under this Agreement by
resignation upon not less than thirty (30) days prior written notice given within a reasonable
period of time not to exceed ninety (90) days after the initial event giving rise to said right to
elect. Notwithstanding the preceding sentence, in the event of a continuing breach of this
Agreement by the MHC, the Bank or the Company, Executive, after giving due notice within the
prescribed time frame of an initial event specified above, shall not waive any of his rights solely
under this Agreement and this Section 4 by virtue of the fact that Executive has submitted his
resignation but has remained in the employment of the MHC, the Bank or the Company and is engaged
in good faith discussions to resolve any occurrence of an event described in clauses (ii) (A), (B),
(C), (D), (E) or (F) above. The Employer shall have at least thirty (30) days to remedy any
condition set forth in clause (ii) (A) through (F), provided, however, that the Employer shall be
entitled to waive such period and make an immediate payment hereunder.

                (iii) Executive’s voluntary resignation from the Employer’s employ on the effective date of,
or at any time following, a Change in Control during the term of this Agreement. For these
purposes, a Change in Control of the MHC, the Bank or the Company shall mean a change in control of
a nature that: (i) would be required to be reported in response to Item 5.01 of the current report
on Form 8-K, as in effect on the date hereof, pursuant to Section 13 or 15(d) of the Securities
Exchange Act of 1934 (the “Exchange Act”); or (ii) results in a Change in Control of the MHC, the
Bank or the Company within the meaning of the Home Owners’ Loan Act, as amended, and applicable
rules and regulations promulgated thereunder, as in effect at the time of the Change in Control
(collectively, the “HOLA”) or (iii) without limitation such a Change in Control shall be deemed to
have occurred at such time as (a) any “person” (as the term is used in Sections 13(d) and 14(d) of
the Exchange Act) other than the Company’s mutual holding company parent, is or becomes the
“beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of
securities of the Company representing 25% or more of the combined voting power of Company’s
outstanding securities except for any securities purchased by the Bank’s employee stock ownership
plan or trust; or (b) individuals who constitute the Board on the date hereof (the “Incumbent
Board”) cease for any reason to constitute at least a majority thereof, provided that any person
becoming a director subsequent to the date hereof whose election was approved by a vote of at least
three quarters of the directors comprising the Incumbent Board, or whose nomination for election by
the Company’s stockholders was approved by the same Nominating Committee serving under an Incumbent
Board, shall be, for purposes of this clause (b), considered as though he were a member of the
Incumbent Board; or (c) a plan of reorganization, merger, consolidation, sale of all or
substantially all the assets of the MHC, the Bank or the Company or similar transaction in which
the Bank or Company is not the surviving institution occurs; or (d) a proxy statement soliciting
proxies from stockholders of the Company, by someone other than the current management of the
Company, seeking stockholder approval of a plan of reorganization, merger or consolidation of the
Company or similar transaction with one or more corporations or financial institutions, and as a
result of such proxy solicitation, a plan of reorganization, merger consolidation or similar
transaction involving the Company is approved by the Company’s Board

4

 

of Directors or the requisite vote of the Company’s stockholders; or (e) a tender offer is
made for 25% or more of the voting securities of the Company and the shareholders owning
beneficially or of record 25% or more of the outstanding securities of the Company have tendered or
offered to sell their shares pursuant to such tender offer and such tendered shares have been
accepted by the tender offeror.

          (b) Upon the occurrence of an Event of Termination, on the Date of Termination, as defined in
Section 7, the Employer shall pay Executive, or, in the event of his subsequent death, his
beneficiary or beneficiaries, or his estate, as the case may be, as severance pay or liquidated
damages, or both, a sum equal to three (3) times the sum of (i) the highest rate of Base Salary and
(ii) the highest rate of bonus awarded to the Executive during the prior three years. Such
payments shall be made in a lump sum and shall not be reduced in the event the Executive obtains
other employment following an Event of Termination. All amounts payable to the Executive shall be
paid within thirty (30) days following the Date of Termination or if Executive is a Specified
Employee (within the meaning of Treasury Regulations §1.409A-1(i)) on the first business day of the
seventh month following the Date of Termination.

          (c) Upon the occurrence of an Event of Termination, the Employer will cause to be continued
life insurance and non-taxable medical and dental coverage substantially identical to the coverage
maintained by the Employer for Executive prior to his termination. Such coverage shall continue for
36 months from the Date of Termination unless the Executive obtains other employment following
termination of employment under which substantially similar benefits are provided and in which the
Executive is eligible to participate.

          (d) For purposes of Section 4, “Event of Termination” as used herein shall mean “Separation
from Service” as defined in Code Section 409A and the Treasury Regulations promulgated thereunder,
provided, however, that the Employer and Executive reasonably anticipate that the level of bona
fide services the Executive would perform after termination would permanently decrease to a level
that is less than 50% of the average level of bona fide services performed (whether as an employee
or an independent contractor) over the immediately preceding 36-month period.

          (e) Notwithstanding the preceding paragraphs of this Section 4, if the aggregate payments or
benefits to be made or afforded to Executive under said paragraphs (the “Termination Benefits”)
would be deemed to include an “excess parachute payment” under Section 280G of the Code or any
successor thereto, such Termination Benefits will be reduced to an amount (the “Non-Triggering
Amount”), the value of which is one dollar ($1.00) less than an amount equal to the total amount of
payments permissible under Section 280G of the Code or any successor thereto. In the event any
change in the Code or regulations thereunder should reduce the amount of payments permissible under
Section 280G of the Code in effect on the date of this Agreement, then the Termination Benefits to
be paid to the Executive shall be determined as if such change in the Code or regulations had not
been made. The allocation of the reduction required hereby among Termination Benefits provided by
the preceding paragraphs of this Section 4 shall be determined by Executive, provided however that
if it is determined that such election by Executive shall be in violation of Code Section 409A, the
allocation of the required reduction shall be pro-rata.

5. TERMINATION UPON DISABILITY, RETIREMENT OR DEATH

          (a) “Disability” or “Disabled” shall be construed to comply with Code Section 409A and shall
be deemed to have occurred if: (i) Executive is unable to engage in any substantial gainful
activity by reason of any medically determinable physical or mental impairment that can be expected
to result in death, or last for a continuous period of not less than 12 months; (ii) by reason of
any medically determinable physical or mental impairment that can be expected to result in death,
or last for continuous period of not less than 12 months, Executive is receiving income replacement
benefits for a period of not less than three months under an accident and health plan covering
employees of the Employer; or (iii) Executive is determined to be totally disabled by the Social
Security Administration. Executive shall be entitled to receive benefits under any short or
long-term disability plan maintained by the Employer. To extent that such benefits are less than
Executive’s Base Salary, the Employer shall pay Executive an amount equal to the difference between
such disability plan benefits and the amount of Executive’s Base Salary for the longer of (i) the
remaining term of this Agreement, or (ii) one year following the termination of his employment due
to Disability. Accordingly, any payments required hereunder shall commence within thirty (30) days
from the Date of Termination.

          (b) Termination by the Employer of the Executive based on “Retirement” shall mean termination
in accordance with the Employer’s retirement policy or in accordance with any retirement
arrangement established with Executive’s consent with respect to him. Upon termination of Executive
upon Retirement, no amounts or benefits shall be due to the Executive under this Agreement, and
Executive shall be entitled to all benefits under any retirement plan of the Employer and other
plans to which Executive is a party.

          (c) In the event of Executive’s death during the term of the Agreement, his estate, legal
representatives or named beneficiaries (as directed by Executive in writing) shall be paid
Executive’s Base Salary as defined in Paragraph 3(a) at the rate in effect at the time Executive’s
death in accordance with its regular payroll practice for a period of one (1) year from the date of
the Executive’s death, and the Employer will continue to provide life insurance and nontaxable
medical and dental benefits previously provided for the Executive’s family for three (3) years
after the Executive’s death.

6. TERMINATION FOR CAUSE

     The term “Termination for Cause” shall mean termination because of the Executive’s personal
dishonesty, willful misconduct, any breach of fiduciary duty involving personal profit, intentional
failure to perform stated duties, willful violation of any law, rule, or regulation (other than
traffic violations or similar offenses) or final cease-and-desist order, or material breach of any
provision of this Agreement. In determining incompetence, the acts or omissions shall be measured
against standards generally prevailing in the savings institutions industry. For purposes of this
paragraph, no act or failure to act on the part of Executive shall be considered “willful” unless
done, or omitted to be done, by the Executive not in good faith and without reasonable belief that
the Executive’s action or omission was in the best interest of the Employer. Notwithstanding the
foregoing, Executive shall not be deemed to have been Terminated for Cause unless and until there
shall have been delivered to him a copy of a resolution duly adopted by the affirmative vote of not
less than three-fourths of the members of the Board at a meeting of the Board called and held for
that purpose (after reasonable notice to Executive and an opportunity for him, together with
counsel, to be heard before the Board), finding that in the

6

 

good faith opinion of the Board, Executive was guilty of conduct justifying Termination for
Cause and specifying the particulars thereof in detail. The Executive shall not have the right to
receive compensation or other benefits for any period after Termination for Cause. Any stock
options granted to Executive under any stock option plan of the Employer or any subsidiary or
affiliate thereof, that have not yet vested shall become null and void effective upon Executive’s
receipt of Notice of Termination for Cause pursuant to Section 7 hereof, and shall not be
exercisable by Executive at any time subsequent to such Termination for Cause.

7. NOTICE

          (a) Any purported termination by the Bank, the Company, or by Executive shall be communicated
by Notice of Termination to the other party hereto. For purposes of this Agreement, a “Notice of
Termination” shall mean a written notice which shall indicate the specific termination provision in
this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination of Executive’s employment under the provision so
indicated.

          (b) “Date of Termination” shall mean (A) if Executive’s employment is terminated for
Disability, thirty (30) days after a Notice of Termination is given (provided that he shall not
have returned to the performance of his duties on a full-time basis during such thirty (30) day
period), (B) if his employment is terminated due to the occurrence of an Event of Termination set
forth under Section 4, thirty (30) days after a Notice of Termination is given unless the Employer
waives its right to cure and agrees to the Event of Termination, and (C) if his employment is
terminated for any other reason, the date specified in the Notice of Termination (which, in the
case of a Termination for Cause, shall not be less than thirty (30) days from the date such Notice
of Termination is given).

          (c) If, within thirty (30) days after any Notice of Termination is given, the party receiving
such Notice of Termination notifies the other party that a dispute exists concerning the
termination, except upon the voluntary termination by the Executive in which case the Date of
Termination shall be the date specified in the Notice, the Date of Termination shall be the date on
which the dispute is finally determined, either by mutual written agreement of the parties, by a
binding arbitration award, or by a final judgment, order or decree of a court of competent
jurisdiction (the time for appeal having expired and no appeal having been perfected) and provided
further that the Date of Termination shall be extended by a notice of dispute only if such notice
is given in good faith and the party giving such notice pursues the resolution of such dispute with
reasonable diligence. Notwithstanding the pendency of any such dispute, the Employer will continue
to pay Executive his full compensation in effect when the notice giving rise to the dispute was
given (including, but not limited to, Base Salary) and continue Executive as a participant in all
compensation, benefit and insurance plans in which he was participating when the notice of dispute
was given, until the dispute is finally resolved in accordance with this Agreement, provided such
dispute is resolved within the term of this Agreement. If such dispute is not resolved within the
term of the Agreement, the Employer shall not be obligated, upon final resolution of such dispute,
to pay Executive compensation and other payments accruing beyond the term of the Agreement. Amounts
paid under this Section shall be offset against or reduce any other amounts due under this
Agreement.

7

 

8. POST-TERMINATION OBLIGATIONS

          (a) All payments and benefits to Executive under this Agreement shall be subject to
Executive’s compliance with paragraph (b) of this Section 8 during the term of this Agreement and
for two (2) full years after the expiration or termination hereof.

          (b) Executive shall, upon reasonable notice, furnish such information and assistance to the
Employer as may reasonably be required by the Employer in connection with any litigation in which
it or any of its subsidiaries or affiliates is, or may become, a party.

9. NON-COMPETITION

          (a) Upon any termination (whether voluntary or involuntary) of Executive’s employment, other
than a termination (whether voluntary or involuntary) in connection with a Change in Control,
Executive agrees not to compete with the MHC, the Bank and the Company for a period of one (1) year
following such termination within one hundred (100) miles of any existing branch of the Bank, the
Bank’s subsidiaries, or any subsidiary of the MHC or the Company, or within one hundred (100) miles
of any office for which the Bank, the Bank’s subsidiaries, the Company or a bank subsidiary of the
Company has filed an application for regulatory approval, determined as of the effective date of
such termination, except as agreed to pursuant to a resolution duly adopted by the Board. Executive
agrees that during such period and within said cities, towns and counties, Executive shall not work
for or advise, consult or otherwise serve with, directly or indirectly, any entity whose business
materially competes with the depository, lending or other business activities of the MHC, the Bank
and/or the Company. The parties hereto, recognizing that irreparable injury will result to the MHC,
the Bank and/or the Company, its business and property in the event of Executive’s breach of this
Subsection 9(a) agree that in the event of any such breach by Executive, the Bank and/or the
Company will be entitled, in addition to any other remedies and damages available, to an injunction
to restrain the violation hereof by Executive, Executive’s partners, agents, servants, employers,
employees and all persons acting for or with Executive. Executive represents and admits that
Executive’s experience and capabilities are such that Executive can obtain employment in a business
engaged in other lines and/or of a different nature than the Bank and/or the Company, and that the
enforcement of a remedy by way of injunction will not prevent Executive from earning a livelihood.
Nothing herein will be construed as prohibiting the Bank and/or the Company from pursuing any other
remedies available to the MHC, the Bank and/or the Company for such breach or threatened breach,
including the recovery of damages from Executive.

          (b) Executive recognizes and acknowledges that the knowledge of the business activities and
plans for business activities of the MHC, the Bank, the Company and affiliates thereof, as it may
exist from time to time, is a valuable, special and unique asset of the business of the MHC, the
Bank and the Company. Executive will not, during or after the term of his employment, disclose any
knowledge of the past, present, planned or considered business activities of the MHC, the Bank, the
Company or affiliates thereof to any person, firm, corporation, or other entity for any reason or
purpose whatsoever (except for such disclosure as may be required to be provided to any federal
banking agency with jurisdiction over the MHC, the Bank, the Company or the Executive).
Notwithstanding the foregoing, Executive may disclose any knowledge of banking, financial and/or
economic principles, concepts or ideas which are not solely and exclusively derived from the
business plans and activities of the MHC, the Bank or the Company, and Executive may disclose any
information regarding the MHC, the

8

 

Bank or the Company which is otherwise publicly available. In the event of a breach or
threatened breach by the Executive of the provisions of this Section 9, the MHC, the Bank and/or
the Company will be entitled to an injunction restraining Executive from disclosing, in whole or in
part, the knowledge of the past, present, planned or considered business activities of the MHC, the
Bank, the Company or affiliates thereof, or from rendering any services to any person, firm,
corporation, other entity to whom such knowledge, in whole or in part, has been disclosed or is
threatened to be disclosed. Nothing herein will be construed as prohibiting the MHC, the Bank or
the Company from pursuing any other remedies availableto the MHC, the Bank or the Company for such
breach or threatened breach, including the recovery of damages from Executive.

10. SOURCE OF PAYMENTS

     All payments provided in this Agreement shall be timely paid in cash, check or direct deposit
from the general funds of the Bank. The MHC and the Company, however, guarantee payment and
provision of all amounts and benefits due hereunder to Executive and, if such amounts and benefits
due from the Bank are not timely paid or provided by the Bank, such amounts and benefits shall be
paid or provided by the MHC or the Company.

11. EFFECT ON PRIOR AGREEMENTS AND EXISTING BENEFITS PLANS

     This Agreement contains the entire understanding between the parties hereto and supersedes any
prior employment agreement between the MHC, the Bank, the Company or any predecessor of the MHC,
the Bank or Company and Executive, except that this Agreement shall not affect or operate to reduce
any benefit or compensation inuring to the Executive of a kind elsewhere provided. No provision of
this Agreement shall be interpreted to mean that Executive is subject to receiving fewer benefits
than those available to him without reference to this Agreement.

12. NO ATTACHMENT

          (a) Except as required by law, no right to receive payments under this Agreement shall be
subject to anticipation, commutation, alienation, sale, assignment, encumbrance, charge, pledge, or
hypothecation, or to execution, attachment, levy, or similar process or assignment by operation of
law, and any attempt, voluntary or involuntary, to affect any such action shall be null, void, and
of no effect.

          (b) This Agreement shall be binding upon, and inure to the benefit of, Executive and the MHC,
the Bank and the Company and their respective successors and assigns.

13. MODIFICATION AND WAIVER

          (a) This Agreement may not be modified or amended except by an instrument in writing signed by
the parties hereto.

          (b) No term or condition of this Agreement shall be deemed to have been waived, nor shall
there be any estoppel against the enforcement of any provision of this Agreement, except by written
instrument of the party charged with such waiver or estoppel. No such written waiver shall be
deemed a continuing waiver unless specifically stated therein, and each such waiver shall operate
only as to the specific term or condition waived and shall not constitute a waiver of such term or
condition for the future as to any act other than that specifically waived.

9

 

14. SEVERABILITY

     If, for any reason, any provision of this Agreement, or any part of any provision, is held
invalid, such invalidity shall not affect any other provision of this Agreement or any part of such
Provision not held so invalid, and each such other provision and part thereof shall, to the full
extent consistent with law, continue in full force and effect.

15. HEADINGS FOR REFERENCE ONLY

     The headings of sections and paragraphs herein are included solely for convenience of
reference and shall not control the meaning or interpretation of any of the provisions of this
Agreement.

16. GOVERNING LAW

     This Agreement shall be governed by the laws of the Commonwealth of Pennsylvania but only to
the extent not superseded by federal law.

17. REQUIRED PROVISIONS

     Notwithstanding anything herein contained to the contrary, any payments to Executive by the
Bank, whether pursuant to this Agreement or otherwise, are subject to and conditioned upon their
compliance with Section 18(k) of the Federal Deposit Insurance Act, 12 U.S.C. § 1828(k), and the
regulations promulgated thereunder in 12 C.F.R. Part 359.

18. ARBITRATION

     Any dispute or controversy arising under or in connection with this Agreement shall be settled
exclusively by arbitration, conducted before a panel of three arbitrators sitting in a location
selected by the employee within one hundred (100) miles from the location of the Bank, in
accordance with the rules of the American Arbitration Association then in effect. Judgment may be
entered on the arbitrator’s award in any court having jurisdiction; provided, however, that
Executive shall be entitled to seek specific performance of his right to be paid until the Date of
termination during the pendency of any dispute or controversy arising under or in connection with
this Agreement.

19. PAYMENT OF LEGAL FEES

     All reasonable legal fees paid or incurred by Executive pursuant to any dispute or question of
interpretation relating to this Agreement shall be paid or reimbursed by the MHC, the Bank or the
Company, provided that the dispute or interpretation has been settled by Executive and the MHC, the
Bank or Company or resolved in the Executive’s favor, and that such reimbursement shall occur no
later than two and one-half months after the dispute is settled or resolved in the Executive’s
favor.

20. INDEMNIFICATION

     The Employer shall provide Executive (including his heirs, executors and administrators) with
coverage under a standard directors’ and officers’ liability insurance policy at its expense, and
shall indemnify Executive (and his heirs, executors and administrators) to the fullest extent

10

 

permitted under applicable law against all expenses and liabilities reasonably incurred by him
in connection with or arising out of any action, suit or proceeding in which he may be involved by
reason of his having been a director or officer of the Employer (whether or not he continues to be
a director or officer at the time of incurring such expenses or liabilities), such expenses and
liabilities to include, but not be limited to, judgments, court costs and attorneys’ fees and the
cost of reasonable settlements (such settlements must be approved by the Board of Directors or
Trustees of the Employer). If such action, suit or proceeding is brought against Executive in his
capacity as an officer or director of the Employer, however, such indemnification shall not extend
to matters as to which Executive is finally adjudged to be liable for willful misconduct in the
performance of his duties.

21. SUCCESSOR TO THE BANK

     The MHC, the Bank and the Company shall require any successor or assignee, whether direct or
indirect, by purchase, merger, consolidation or otherwise, to all or substantially all the business
or assets of the MHC, the Bank or the Company, expressly and unconditionally to assume and agree to
perform the MHC, the Bank and/or Company’s obligations under this Agreement, in the same manner and
to the same extent that the MHC, the Bank and/or the Company would be required to perform if no
such succession or assignment had taken place.
