 2. Lease Grant. Landlord leases the Premises to Tenant and Tenant leases the Premises from Landlord,
together with the right in common with others to use any portions of the Property (defined below) that are designated by Landlord for the common use of tenants and others, such as sidewalks, common corridors, vending areas, lobby areas and, with
respect to multi-tenant floors, restrooms and elevator foyers (the “Common Areas”), “Property” means the Building and the parcel(s) of land on which it is located as more fully described on
Exhibit A-2 and any adjacent parcels of land owned by Landlord or its Affiliates (defined below), together with all other buildings and improvements located thereon; and the Building garage(s) and other improvements serving the
Building, if any, and the parcel(s) of land on which they are located. 
  
 3. Term; Adjustment of Commencement Date; Early Access 
  
 A. Term. This Lease shall govern the relationship between Landlord and Tenant with respect to the Premises from the Effective Date through the last day of the Term specified in Section 1.G (the
“Expiration Date”), unless terminated early in accordance with this Lease. The Term of this Lease (as specified in Section 1.G) shall commence on the “Commencement Date”, which shall be
December 28, 2004. The “Rent Commencement Date” shall be the earlier of (1) the date on which the Landlord Work (defined below) is Substantially Complete, as determined pursuant to the Work Letter (defined below),
or (2) the date on which the Landlord Work would have been Substantially Complete but for Tenant Delay, as such term is defined in the Work Letter, or (3) the date Tenant takes possession of any part of the Premises for purposes of
conducting business. If Landlord is delayed in delivering possession of the Premises or any other space due to any reason, including Landlord’s failure to Substantially Complete the Landlord Work by the Estimated Commencement Date, the holdover
or unlawful possession of such space by any third party, or for any other reason, such delay shall not be a default by Landlord, render this Lease void or voidable, or otherwise render Landlord liable for damages. Promptly after the determination of
the Commencement Date, the Expiration Date, the Rent schedule and any other variable matters, Landlord shall prepare and deliver to Tenant a commencement letter agreement substantially in the form attached as Exhibit C. If such
commencement letter is not executed by Tenant within 30 days after delivery of same by Landlord, then Tenant shall be deemed to have agreed with the matters set forth therein. Notwithstanding any other provision of this Lease to the contrary, if the
Expiration Date would otherwise occur on a date other than the last day of a calendar month, then the Term shall be automatically extended to include the last day of such calendar month, which shall become the Expiration Date. “Landlord
Work” means the work, if any, that Landlord is obligated to perform in the Premises pursuant to a separate work letter agreement (the “Work Letter”), if any, attached as Exhibit D. If a Work Letter
is not attached to this Lease or if an attached Work Letter does not require Landlord to perform any work, the occurrence of the Commencement Date shall not be conditioned upon the performance of work by Landlord. 
  
 B. Acceptance of Premises. The Premises are accepted by
Tenant in “as is” condition and configuration subject to (1) any Landlord obligation to perform Landlord Work, and (2) any latent defects in the Premises of which Tenant notifies Landlord within one year after the Commencement
Date [other than work performed by Tenant Parties (defined below)]. TENANT HEREBY AGREES THAT THE PREMISES ARE IN GOOD ORDER AND SATISFACTORY CONDITION AND THAT, EXCEPT AS OTHERWISE EXPRESSLY SET FORTH IN THIS LEASE, THERE ARE NO REPRESENTATIONS
OR WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, BY LANDLORD REGARDING THE PREMISES, THE BUILDING OR THE PROPERTY. 
  
 C. Early Access. Prior to the date the Landlord Work is Substantially Complete, Tenant’s access to the Premises shall be permitted
only with the prior written consent of Landlord. Early access to the Premises shall be subject to the terms and conditions of this Lease and Tenant shall pay Rent (defined in Section 4.A) to Landlord for each day of such early access.
However, if such early access to the Premises is permitted by Landlord for the sole purpose of performing improvements or installing furniture, equipment or other personal property, Tenant shall not be required to pay Base Rent and Tenant’s Pro
Rata Share of Excess Operating Expenses and Tenant’s Pro Rata Share of electrical and other costs under Section 4.H for any days of such early access; provided however, Tenant shall pay for the cost of any other Building services
requested by Tenant (e.g., freight elevator usage). 
  

 3 








 4. Rent 
  
 A. Payments. As consideration for this Lease, commencing on the Rent Commencement Date, Tenant shall pay Landlord, without any demand,
setoff or deduction, the total amount of Base Rent, Tenant’s Pro Rata Share of Excess Operating Expenses (defined in Section 4.B) and any and all other sums payable by Tenant under this Lease (all of which are sometimes collectively
referred to as “Rent”). Provided no event of default has occurred, Landlord agrees to abate the Base Rent due and payable for the first twelve (12) months after the Rent Commencement Date. Tenant shall pay and be liable
for all rental, sales and use taxes (but excluding income taxes), if any, imposed upon or measured by Rent under applicable Law. The monthly Base Rent and Tenant’s Pro Rata Share of Excess Operating Expenses shall be due and payable in advance
on the first day of each calendar month without notice or demand, provided that the installment of Base Rent for the first full calendar month of the Term shall be payable upon the execution of this Lease by Tenant. All other items of Rent shall be
due and payable by Tenant on or before 30 days after billing by Landlord. All payments of Rent shall be by good and sufficient check or by other means (such as automatic debit or electronic transfer) acceptable to Landlord. If the Term commences on
a day other than the first day of a calendar month, the monthly Base Rent and Tenant’s Pro Rata Share of any Excess Operating Expenses for the month shall be prorated on a daily basis based on a 360 day calendar year. Landlord’s acceptance
of less than the correct amount of Rent shall be considered a payment on account of the earliest Rent due. No endorsement or statement on a check or letter accompanying a check or payment shall be considered an accord and satisfaction, and either
party may accept such check or payment without such acceptance being considered a waiver of any rights such party may have under this Lease or applicable Law. Tenant’s covenant to pay Rent is independent of every other covenant in this Lease.

  
 B. Excess Operating Expenses. Tenant shall
pay Tenant’s Pro Rata Share of the amount, if any, by which Operating Expenses (defined in Section 4.D) for each calendar year during the Term exceed Operating Expenses for the Base Year (the “Excess Operating
Expenses”). If Operating Expenses in any calendar year decrease below the amount of Operating Expenses for the Base Year, Tenant’s Pro Rata Share of Operating Expenses for that calendar year shall be $0. In no event shall Base Rent
be reduced if Operating Expenses for any calendar year are less than Operating Expenses for the Base Year. On or about January 1 of each calendar year, Landlord shall provide Tenant with a good faith estimate of the Excess Operating Expenses
for such calendar year during the Term. On or before the first day of each month, Tenant shall pay to Landlord a monthly installment equal to one-twelfth of Tenant’s Pro Rata Share of Landlord’s estimate of the Excess Operating Expenses.
If Landlord determines that its good faith estimate of the Excess Operating Expenses was incorrect, Landlord may provide Tenant with a revised estimate. After its receipt of the revised estimate, Tenant’s monthly payments shall be based upon
the revised estimate. If Landlord does not provide Tenant with an estimate of the Excess Operating Expenses by January 1 of a calendar year, Tenant shall continue to pay monthly installments based on the most recent estimate(s) until Landlord
provides Tenant with the new estimate. Upon delivery of the new estimate, an adjustment shall be made for any month for which Tenant paid monthly installments based on the same year’s prior incorrect estimate(s). Tenant shall pay Landlord the
amount of any underpayment within 30 clays after receipt of the new estimate. Any overpayment shall be credited against the next sums due and owing by Tenant or, if no further Rent is due, refunded directly to Tenant within 30 days of determination.
The obligation of Tenant to pay for Excess Operating Expenses as provided herein shall survive the expiration or earlier termination of this Lease. 
  
 C. Reconciliation of Operating Expenses. Within 120 days after the end of each calendar year or as soon thereafter as is practicable,
Landlord shall furnish Tenant with a statement of the actual Operating Expenses and Excess Operating Expenses for such calendar year. If the most recent estimated Excess Operating Expenses paid by Tenant for such calendar year are more than the
actual Excess Operating Expenses for such calendar year, Landlord shall apply any overpayment by Tenant against Rent due or next becoming due; provided, if the Term expires before the determination of the overpayment, Landlord shall, within 30 days
of determination, refund any overpayment to Tenant after first deducting the amount of Rent due. If the most recent estimated Excess Operating Expenses paid by Tenant for the prior calendar year are 

  

 4 








 
less than the actual Excess Operating Expenses for such year, Tenant shall pay Landlord, within 30 days after its receipt of the statement of Operating
Expenses, any underpayment for the prior calendar year. 
  
 D. Operating Expenses Defined. “Operating Expenses” means all costs and expenses incurred or accrued in each calendar year in connection with the ownership, operation, maintenance, management,
repair and protection of the Property which are directly attributable or reasonably allocable to the Building, including Landlord’s personal property used in connection with the Property and including all costs and expenditures relating to the
following: 
  
 1. Operation, maintenance, repair
and replacements of any part of the Property, including the mechanical, electrical, plumbing, HVAC, vertical transportation, fire prevention and warning and access control systems; materials and supplies (such as building standard light bulbs and
ballasts); equipment and tools; floor, wall and window coverings; personal property; required or beneficial easements; and related service agreements and rental expenses. 
  

 2. Administrative costs and management fees, including accounting, information and professional services (except for
negotiations and disputes with specific tenants not affecting other parties); management office(s); and wages, salaries, benefits, reimbursable expenses and taxes (or allocations thereof) for full and part time personnel involved in operation,
maintenance and management. 
  
 3. Janitorial
service; window cleaning; waste disposal; gas, water and sewer and other utility charges (including add-ons); and landscaping, including all applicable tools and supplies. 
  
 4. Property, liability and other insurance coverages carried by Landlord, including deductibles and risk
retention programs and a proportionate allocation of the cost of blanket insurance policies maintained by Landlord and/or its Affiliates (defined below). 
  
 5. Real estate taxes, assessments, business taxes, excises, association dues, fees, levies, charges and other taxes of every kind and
nature whatsoever, general and special, extraordinary and ordinary, foreseen and unforeseen, including interest on installment payments, which may be levied or assessed against or arise in connection with ownership, use, occupancy, rental, operation
or possession of the Property (including personal property taxes for property that is owned by Landlord and used in connection with the operation, maintenance and repair of the Property), or substituted, in whole or in part, for a tax previously in
existence by any taxing authority, or assessed in lieu of a tax increase, or paid as rent under any ground lease. Real estate taxes do not include Landlord’s income, franchise or estate taxes (except to the extent such excluded taxes are
assessed in lieu of taxes included above). 
  
 6.
Compliance with Laws, including license, permit and inspection fees (but not in duplication of capital expenditures amortized as provided in Section 4.D(9)); and all expenses and fees, including attorneys’ fees and court or other
venue of dispute resolution costs, incurred in negotiating or contesting real estate taxes or the validity and/or applicability of any governmental enactments which may affect Operating Expenses; provided Landlord shalt credit against Operating
Expenses any refunds received from such negotiations or contests to the extent originally included in Operating Expenses (less Landlord’s costs). 
  
 7. Building safety services, to the extent provided or contracted for by Landlord. 
  
 8. Goods and services purchased from Landlord’s
subsidiaries and Affiliates to the extent the cost of same is generally consistent with rates charged by unaffiliated third parties for similar goods and services. 
  
 9. Amortization of capital expenditures incurred: (a) to conform with Laws; (b) to provide or
maintain building standards (other than building standard tenant improvements); or (c) with the intention of promoting safety or reducing or controlling increases in Operating Expenses, such as lighting retrofit and installation of energy
management systems. Such expenditures shall be amortized uniformly over the following periods of time (together with interest on the unamortized balance at the Prime Rate (defined in Section 19.B) as of the date incurred plus 2%): for
building improvements, the 

  

 5 








 
shorter of 10 years or the estimated useful life of the improvement; and for all other items, 3 years for expenditures under $50,000 and 5 years for
expenditures in excess of $50,000. Notwithstanding the foregoing, Landlord may elect to amortize capital expenditures under this subsection over a longer period of time based upon (i) the purpose and nature of the expenditure, (ii) the
relative capital burden on the Property, (iii) for cost savings projects, the anticipated payback period, and (iv) otherwise in accordance with sound real estate accounting principles consistently applied. 
  
 E. Exclusions from Operating Expenses. Operating Expenses
exclude the following expenditures: 
  
 1.
Leasing commissions, attorneys’ fees and other expenses related to leasing tenant space and constructing improvements for the sole benefit of an individual tenant. 
  

 2. Goods and services furnished to an individual tenant of the Building which are above building standard and which are
separately reimbursable directly to Landlord in addition to Excess Operating Expenses. 
  
 3. Repairs, replacements and general maintenance paid by insurance proceeds or condemnation proceeds, 
  
 4. Except as provided in Section 4.D(9),
depreciation, amortization, interest payments on any encumbrances on the Property and the cost of capital improvements or additions. 
  
 5. Costs of installing any specialty service, such as an observatory, broadcasting facility, luncheon club, or athletic or recreational
club. 
  
 6. Expenses for repairs or maintenance
related to the Property which have been reimbursed to Landlord pursuant to warranties or service contracts, 
  
 7. Costs (other than maintenance costs) of any art work (such as sculptures or paintings) used to decorate the Building. 
  
 8. Principal payments on indebtedness secured by liens
against the Property, or costs of refinancing such indebtedness. 
  
 9. Electrical service costs paid separately pursuant to Section 4.H. 
  
 F. Proration of Operating Expenses; Adjustments. If Landlord incurs Operating Expenses for the Property together with one or more other
buildings or properties, whether pursuant to a reciprocal easement agreement, common area agreement or otherwise, the shared costs and expenses shall be equitably prorated and apportioned by Landlord between the Property and the other buildings or
properties. If the Building is not 100% occupied during any calendar year or partial calendar year or if Landlord is not supplying services to 100% of the total Rentable Square Footage of the Building at any time during a calendar year or partial
calendar year, Operating Expenses shall be determined as if the Building had been 100% occupied and Landlord had been supplying services to 100% of the Rentable Square Footage of the Building during that calendar year. If Tenant pays for
Tenant’s Pro Rata Share of Operating Expenses based on increases over a “Base Year” and Operating Expenses for a calendar year are determined as provided in the prior sentence, Operating Expenses for the Base Year shall
also be determined as if the Building had been 100% occupied and Landlord had been supplying services to 100% of the Rentable Square Footage of the Building. The extrapolation of Operating Expenses under this Section shall be performed by Landlord
by adjusting the cost of those components of Operating Expenses that are impacted by changes in the occupancy of the Building. 
  
 G. Audit Rights. Within 60 days after Landlord furnishes its statement of actual Operating Expenses for any calendar year (including the
Base Year) (the “Audit Election Period”), Tenant may, at its expense, elect to audit Landlord’s Operating Expenses for such calendar year only, subject to the following conditions: (1) there is no uncured event of
default under this Lease; (2) the audit shall be prepared by an independent certified public accounting firm of recognized national standing; (3) in no event shall any audit be performed by a firm retained on a “contingency fee”
basis; (4) the audit shall commence within 30 days after Landlord makes Landlord’s books and records available to Tenant’s auditor and shall conclude within 

  

 6 








 
60 days after commencement; (5) the audit shall be conducted during Landlord’s normal business hours at the location where Landlord maintains its
books and records and shall not unreasonably interfere with the conduct of Landlord’s business; (6) Tenant and its accounting firm shall treat any audit in a confidential manner and shall each execute Landlord’s confidentiality
agreement for Landlord’s benefit prior to commencing the audit; and (7) the accounting firm’s audit report shall, at no charge to Landlord, be submitted in draft form for Landlord’s review and comment before the final approved
audit report is delivered to Landlord, and any reasonable comments by Landlord shall be incorporated into the final audit report. Notwithstanding the foregoing, Tenant shall have no right to conduct an audit if Landlord furnishes to Tenant an audit
report for the calendar year in question prepared by an independent certified public accounting firm of recognized national standing (whether originally prepared for Landlord or another party). This paragraph shall not be construed to limit,
suspend, or abate Tenant’s obligation to pay Rent when due, including estimated Excess Operating Expenses. Landlord shall credit any overpayment determined by the final approved audit report against the next Rent due and owing by Tenant or, if
no further Rent is due, refund such overpayment directly to Tenant within 30 days of determination. Likewise, Tenant shall pay Landlord any underpayment determined by the final approved audit report within 30 days of determination. The foregoing
obligations shall survive the expiration or termination of this Lease. If Tenant does not give written notice of its election to audit Landlord’s Operating Expenses during the Audit Election Period, Landlord’s Operating Expenses for the
applicable calendar year shall be deemed approved for all purposes, and Tenant shall have no further right to review or contest the same. The right to audit granted hereunder is personal to the initial Tenant named in this Lease and to any assignee
under a Permitted Transfer (defined below) and shall not be available to any subtenant under a sublease of the Premises. 
  
 H. Electrical Costs. In addition to the Excess Operating Expenses, and as a separate obligation, Tenant shall pay Landlord Tenant’s
Pro Rata Share of the following costs incurred by Landlord which are directly attributable or reasonably allocable to the Building: (1) electrical services used in the operation, maintenance and use of the Property; (2) sales, use, excise
and other taxes assessed by governmental authorities on electrical services supplied to the Property; and (3) other costs of providing electrical services to the Property. Tenant shall, with each monthly payment of Base Rent, pay
Landlord’s estimate of Tenant’s Pro Rata Share of such electrical service costs in the same manner as provided for Operating Expenses in Sections 4.B, C, and F. 
  
 5. Tenant’s Use of Premises 
  
 A. Permitted Uses. The Premises shall be used only for
general office use (the “Permitted Use”) and for no other use whatsoever. Tenant shall not use or permit the use of the Premises for any purpose which is illegal, creates obnoxious odors (including tobacco smoke), noises or
vibrations, is dangerous to persons or property, could increase Landlord’s insurance costs, or which, in Landlord’s reasonable opinion, unreasonably disturbs any other tenants of the Building or interferes with the operation or maintenance
of the Property or any work by Landlord or its contractors in the Premises. Except as provided below, the following uses are expressly prohibited in the Premises: schools, government offices or agencies; personnel agencies; collection agencies;
credit unions; data processing, telemarketing or reservation centers; medical treatment and health care; radio, television or other telecommunications broadcasting; restaurants and other retail; customer service offices of a public utility company;
or any other purpose which would, in Landlord’s reasonable opinion, impair the reputation or quality of the Building, overburden any of the Building systems, Common Areas or parking facilities (including any use which would create a population
density in the Premises which is in excess of the density which is standard for the Building), impair Landlord’s efforts to lease space or otherwise interfere with the operation of the Property. Notwithstanding the foregoing, the following
ancillary uses are permitted in the Premises only so long as they do not, in the aggregate, occupy more than 10% of the Rentable Square Footage of the Premises or any single floor (whichever is less): (1) the following services provided by
Tenant exclusively to its employees: schools, training and other educational services; credit unions; and similar employee services; and (2) the following services directly and exclusively supporting Tenant’s business: telemarketing;
reservations; storage; data processing; debt collection; and similar support services.

 B. Compliance with Laws. Tenant shall comply with all Laws regarding the operation of
Tenant’s business and the use, condition, configuration and occupancy of the Premises and the use of the Common Areas. Tenant, within 10 days after receipt, shall provide Landlord with copies of any notices Tenant receives regarding a violation
or alleged or potential violation of any Laws. Tenant shall comply with the rules and regulations of the Building attached as Exhibit B and such other reasonable rules and regulations (or modifications thereto) adopted by Landlord from
time to time. Such rules and regulations will be applied in an equitable manner as determined by Landlord. Tenant shall also cause its agents, contractors, subcontractors, employees, customers, and subtenants to comply with all rules and
regulations. 
  
 C. Tenant’s Security
Responsibilities. Tenant shall (1) lock the doors to the Premises and take other reasonable steps to secure the Premises and the personal property of all Tenant Parties (defined in Section 13) and any of Tenant’s transferees,
contractors or licensees in the Common Areas and parking facilities of the Building and Property, from unlawful intrusion, theft, fire and other hazards; (2) keep and maintain in good working order all security and safety devices installed in
the Premises by or for the benefit of Tenant (such as locks, smoke detectors and burglar alarms); and (3) cooperate with Landlord and other tenants in the Building on Building safety matters. Tenant acknowledges that any security or safety
measures employed by Landlord are for the protection of Landlord’s own interests; that Landlord is not a guarantor of the security or safety of the Tenant Parties or their property; and that such security and safety matters are the
responsibility of Tenant and the local law enforcement authorities. 
  
 6. Security Deposit. The Security Deposit shall be delivered to Landlord upon the execution of this Lease by Tenant and shall be held by Landlord (without liability for interest, except to the extent required by Law) as security for the
performance of Tenant’s obligations under this Lease. The Security Deposit is not an advance payment of Rent or a measure of Tenant’s liability for damages. Landlord may, from time to time while an event of default remains uncured, without
prejudice to any other remedy, use all or a portion of the Security Deposit to satisfy past due Rent, cure any uncured default by Tenant, or repay Landlord for damages and charges for which Tenant is legally liable under this Lease or resulting from
Tenant’s breach of this Lease. If Landlord uses the Security Deposit, Tenant shall on demand restore the Security Deposit to its original amount and such use by Landlord of the Security Deposit shall not constitute a cure of the existing event
of default until such time as the entire amount owing to Landlord is paid in full and the Security Deposit is fully restored. Provided that Tenant has performed all of its obligations hereunder, Landlord shall return any unapplied portion of the
Security Deposit to Tenant within 30 days after the later to occur of: (A) the date Tenant surrenders possession of the Premises to Landlord in accordance with this Lease; or (B) the Expiration Date. Tenant does hereby authorize Landlord
to withhold from the Security Deposit all amounts allowed by Law and the amount reasonably anticipated by Landlord to be owed by Tenant as a result of an underpayment of Tenant’s Pro Rata Share of any Excess Operating Expenses for the final
year of the Term. To the fullest extent permitted by applicable Law, Tenant agrees that the provisions of this Article 6 shall supersede and replace all statutory rights of Tenant under applicable Law regarding the retention, application or
return of security deposits. If Landlord transfers its interest in the Premises, Landlord shall assign the Security Deposit to the transferee and, following the assignment and the delivery to Tenant of an acknowledgement of the transferee’s
responsibility for the Security Deposit if required by Law, Landlord shall have no further liability for the return of the Security Deposit. Landlord shall not be required to keep the Security Deposit separate from its other accounts. 
  
 7. Services Furnished by Landlord. 
  
 A. Standard Services. Subject to the provisions of this
Lease, Landlord agrees to furnish (or cause a third party provider to furnish) the following services to Tenant during the Term: 
  
 1. Water service for use in the lavatories on each floor on which the Premises are located. 
  
 2. Heat and air conditioning in season during Normal
Business Hours, at such temperatures and in such amounts as required by governmental authority or as Landlord determines are standard for the Building. Tenant, upon such notice as is reasonably required by Landlord, and subject to the capacity of
the Building systems, may request HVAC service during hours other than Normal Business Hours. 

  

 8 








 
Tenant shall pay Landlord for such additional service at a rate equal to $70.00 per operating hour per floor (the “Hourly HVAC
Charge”). Landlord shall have the right, upon 30 days prior written notice to Tenant, to adjust the Hourly HVAC Charge from time to time, but not more than once per calendar year, based proportionately upon increases in HVAC costs,
which costs include utilities, taxes, surcharges, labor, equipment, maintenance and repair. 
  
 3. Maintenance and repair of the Property as described in Section 9.B. 
  
 4. Janitorial service five days per week (excluding
Holidays), as determined by Landlord. If Tenant’s use of the Premises, floor covering or other improvements require special services in excess of the standard services for the Building, Tenant shall pay the additional cost attributable to the
special services. 
  
 5. Elevator service,
subject to proper authorization and Landlord’s policies and procedures for use of the elevator(s) in the Building. 
  
 6. Exterior window washing at such intervals as determined by Landlord. 
  
 7. Electricity to the Premises for general office use, in accordance with and subject to the terms and
conditions in Article 8. 
  
 B. Service
Interruptions. For purposes of this Lease, a “Service Failure” shall mean any interruption, suspension or termination of services being provided to Tenant by Landlord or by third-party providers, whether engaged by Tenant or
pursuant to arrangements by such providers with Landlord, which are due to (1) the application of Laws; (2) the failure, interruption or malfunctioning of any electrical or mechanical equipment, utility or other service to the Building or
Property; (3) the performance of repairs, maintenance, improvements or alterations; or (4) the occurrence of any other event or cause whether or not within the reasonable control of Landlord. No Service Failure shall render Landlord liable
to Tenant, constitute a constructive eviction of Tenant, give rise to an abatement of Rent, or relieve Tenant from the obligation to fulfill any covenant or agreement. In no event shall Landlord be liable to Tenant for any loss or damage, including
the theft of Tenant’s Property (defined in Article 14), arising out of or in connection with any Service Failure or the failure of any Building safety services, personnel or equipment. 
  
 C. Third Party Services. If Tenant desires any service which
Landlord has not specifically agreed to provide in this Lease, such as private security systems or telecommunications services serving the Premises, Tenant shall procure such service directly from a reputable third party service provider
(“Provider”) for Tenant’s own account. Tenant shall require each Provider to comply with the Building’s rules and regulations, all Laws, and Landlord’s reasonable policies and practices for the Building. Tenant
acknowledges Landlord’s current policy that requires all Providers utilizing any area of the Property outside the Premises to be approved by Landlord and to enter into a written agreement acceptable to Landlord prior to gaining access to, or
making any installations in or through, such area. Accordingly, Tenant shall give Landlord written notice sufficient for such purposes. 
  
 8. Use of Electrical Services by Tenant. 
  
 A. Landlord’s Electrical Service. Subject to the terms of this Lease, Landlord shall furnish building standard electrical service to
the Premises sufficient to operate customary lighting, office machines and other equipment of similar low electrical consumption. Landlord may, at any time and from time to time, calculate Tenant’s actual electrical consumption in the Premises
by a survey conducted by a reputable consultant selected by Landlord, all at Tenant’s expense. The cost of any electrical consumption in excess of that which Landlord determines is standard for the Building shall be paid by Tenant in accordance
with Section 8.D. The furnishing of electrical services to the Premises shall be subject to the rules, regulations and practices of the supplier of such electricity and of any municipal or other governmental authority regulating the
business of providing electrical utility service. Landlord shall not be liable or responsible to Tenant for any loss, damage or expense which Tenant may sustain or incur if either the quantity or character of the electrical service is changed or is
no longer available or no longer suitable for Tenant’s requirements. 
  

 9 








 B. Selection of Electrical Service Provider. Landlord shall have and retain the sole
right to select the provider of electrical services to the Building and/or the Property. To the fullest extent permitted by Law, Landlord shall have the continuing right to change such utility provider. All charges and expenses incurred by Landlord
due to any such changes in electrical services, including maintenance, repairs, installation and related costs, shall be included in the electrical services costs referenced in Section 4.H, unless paid directly by Tenant. 
  
 C. Submetering. Landlord shall have the continuing right,
upon 30 days written notice, to install a submeter for the Premises at Tenant’s expense. If submetering is installed for the Premises, Landlord may charge for Tenant’s actual electrical consumption monthly in arrears for the kilowatt hours
used, a rate per kilowatt hour equal to that charged to Landlord by the provider of electrical service to the Building during the same period of time (plus, to the fullest extent permitted by applicable Laws, an administrative fee equal to 15% of
such charge), except as to electricity directly purchased by Tenant from third party providers after obtaining Landlord’s consent to the same. In the event Landlord is unable to determine the exact kilowatt hourly charge during the period of
time, Landlord shall use the average kilowatt hourly charge to the Building for the first billing cycle ending after the period of time in question. Even if the Premises are submetered, Tenant shall remain obligated to pay Tenant’s Pro Rata
Share of the cost of electrical services as provided in Section 4.H, except that Tenant shall be entitled to a credit against electrical services costs equal to that portion of the amounts actually paid by Tenant separately and directly
to Landlord which are attributable to building standard electrical services submetered to the Premises. 
  
 D. Excess Electrical Service. Tenant’s use of electrical service shall not exceed, in voltage, rated capacity, use beyond Normal
Business Hours or overall load, that which Landlord deems to be standard for the Building. If Tenant requests permission to consume excess electrical service, Landlord may refuse to consent or may condition consent upon conditions that Landlord
reasonably elects (including the installation of utility service upgrades, meters, submeters, air handlers or cooling units). The costs of any approved additional consumption (to the extent permitted by Law), installation and maintenance shall be
paid by Tenant. 
  
 9. Repairs and Alterations 
  
 A. Tenant’s Repair Obligations. Tenant shall keep the
Premises in good condition and repair, ordinary wear and tear excepted. Tenant’s repair obligations include, without limitation, repairs to: (1) floor covering and/or raised flooring; (2) interior partitions; (3) doors;
(4) the interior side of demising walls; (5) electronic, phone and data cabling and related equipment (collectively, “Cable”) that is installed by or for the benefit of Tenant whether located in the Premises or in
other portions of the Building; (6) supplemental air conditioning units, private showers and kitchens, including hot water heaters, plumbing, dishwashers, ice machines and similar facilities serving Tenant exclusively; (7) phone rooms used
exclusively by Tenant; (8) Alterations (defined below) performed by contractors retained by Tenant, including related HVAC balancing; and (9) all of Tenant’s furnishings, trade fixtures, equipment and inventory. Prior to performing
any such repair obligation, Tenant shall give written notice to Landlord describing the necessary maintenance or repair. Upon receipt of such notice, Landlord may elect either to perform any of the maintenance or repair obligations specified in such
notice, or require that Tenant perform such obligations by using contractors approved by Landlord. All work shall be performed at Tenant’s expense in accordance with the rules and procedures described in Section 9.C below. If Tenant
fails to make any repairs to the Premises for more than 15 days after notice from Landlord (although notice shall not be required if there is an emergency), Landlord may, in addition to any other remedy available to Landlord, make the repairs, and
Tenant shall pay to Landlord the reasonable cost of the repairs within 30 days after receipt of an invoice, together with an administrative charge in an amount equal to 15% of the cost of the repairs. 
  
 B. Landlord’s Repair Obligations. Landlord shall keep
and maintain in good repair and working order and make repairs to and perform maintenance upon: (1) structural elements of the Building; (2) standard mechanical (including HVAC), electrical, plumbing and fire/life safety systems serving
the Building generally; (3) Common Areas; (4) the roof of the Building; (5) exterior windows of the Building; and 

  

 10 








 
(6) elevators serving the Building. Landlord shall promptly make repairs (taking into account the nature and urgency of the repair) for which Landlord
is responsible. If any of the foregoing maintenance or repair is necessitated due to the acts or omissions of any Tenant Party (defined in Section 13), Tenant shall pay the costs of such repairs or maintenance to Landlord within 30 days
after receipt of an invoice, together with an administrative charge in an amount equal to 15% of the cost of the repairs. 
  
 C. Alterations 
  
 1. When Consent Is Required. Tenant shall not make alterations, additions or improvements to the Premises or install any Cable in
the Premises or other portions of the Building (collectively, “Alterations”) without first obtaining the written consent of Landlord in each instance. However, Landlord’s consent shall not be required for any Alteration
that satisfies all of the following criteria (a “Minor Alteration”): (a) is of a cosmetic nature such as painting, wallpapering, hanging pictures and installing carpeting; (b) is not visible from outside the
Premises or Building; (c) will not affect the systems or structure of the Building; and (d) does not require work to be performed inside the walls or above the ceiling of the Premises. 
  
 2. Requirements For All Alterations, Including Minor
Alterations. Prior to starting work on any Alteration, Tenant shall furnish to Landlord for review and approval: plans and specifications; names of proposed contractors (provided that Landlord may designate specific contractors with respect to
Building systems); copies of contracts; necessary permits and approvals; evidence of contractors’ and subcontractors’ insurance; and Tenant’s security for performance of the Alteration. Changes to the plans and specifications must
also be submitted to Landlord for its approval. Some of the foregoing requirements may be waived by Landlord for the performance of specific Minor Alterations; provided that such waiver is obtained in writing prior to the commencement of such Minor
Alterations. Landlord’s waiver on one occasion shall not waive Landlord’s right to enforce such requirements on any other occasion. Alterations shall be constructed in a good and workmanlike manner using materials of a quality that is at
least equal to the quality designated by Landlord as the minimum standard for the Building. Landlord may designate reasonable rules, regulations and procedures for the performance of Alterations in the Building and, to the extent reasonably
necessary to avoid disruption to the occupants of the Building, shall have the right to designate the time when Alterations may be performed. Tenant shall reimburse Landlord within 30 days after receipt of an invoice for out-of-pocket sums paid by
Landlord for third party examination of Tenant’s plans for Alterations. In addition, within 30 days after receipt of an invoice from Landlord, Tenant shall pay to Landlord a fee equal to 15% of the total cost of such Alterations for
Landlord’s oversight and coordination of any Alterations. No later than 30 days after completion of the Alterations, Tenant shall furnish “as-built” plans (which shall not be required for Minor Alterations), completion affidavits,
flail and final waivers of liens, receipts and bills covering all labor and materials. Tenant shall assure that the Alterations comply with all insurance requirements and Laws. 
  
 3. Landlord’s Liability For Alterations. Landlord’s approval of an Alteration shall not be
a representation by Landlord that the Alteration complies with applicable Laws or will be adequate for Tenant’s use. Tenant acknowledges that Landlord is not an architect or engineer, and that the Alterations will be designed and/or constructed
using independent architects, engineers and contractors. Accordingly, Landlord does not guarantee or warrant that the applicable construction documents will comply with Laws or be free from errors or omissions, or that the Alterations will be free
from defects, and Landlord will have no liability therefor. 
  
 10. Entry by Landlord. Landlord, its agents, contractors and representatives may enter the Premises to inspect or show the Premises, to clean and make repairs, alterations or additions to the Premises, and to conduct or facilitate repairs,
alterations or additions to any portion of the Building, including other tenants’ premises. Except in emergencies or to provide janitorial and other Building services after Normal Business Hours, Landlord shall provide Tenant with reasonable
prior notice of entry into the Premises, which may be given orally. Landlord shall have the right to temporarily close all or a portion of the Premises to perform repairs, alterations 

  

 11 








 
and additions, if reasonably necessary for the protection and safety of Tenant and its employees. Except in emergencies, Landlord will not close the Premises
if the work can reasonably be completed on weekends and after Normal Business Hours; provided, however, that Landlord is not required to conduct work on weekends or after Normal Business Hours if such work can be conducted without closing the
Premises. Entry by Landlord for any such purposes shall not constitute a constructive eviction or entitle Tenant to an abatement or reduction of Rent. 
  
 11. Assignment and Subletting 
  
 A. Landlord’s Consent Required. Subject to the remaining provisions of this Article 11, but notwithstanding anything to the
contrary contained elsewhere in this Lease, Tenant shall not assign, transfer or encumber any interest in this Lease (either absolutely or collaterally) or sublease or allow any third party to use any portion of the Premises (collectively or
individually, a “Transfer”) without the prior written consent of Landlord, which consent shall not be unreasonably withheld. Without limitation, Tenant agrees that Landlord’s consent shall not be considered unreasonably
withheld if: (1) the proposed transferee’s financial condition does not meet the criteria Landlord uses to select Building tenants having similar leasehold obligations; (2) the proposed transferee is a governmental organization or
present occupant of the Property, or Landlord is otherwise engaged in lease negotiations with the proposed transferee for other premises in the Property; (3) any uncured event of default exists under this Lease (or a condition exists which,
with the passage of time or giving of notice, would become an event of default); (4) any portion of the Building or Premises would likely become subject to additional or different Laws as a consequence of the proposed Transfer; (5) the
proposed transferee’s use of the Premises conflicts with the Permitted Use or any exclusive usage rights granted to any other tenant in the Building; (6) the use, nature, business, activities or reputation in the business community of the
proposed transferee (or its principals, employees or invitees) does not meet Landlord’s standards for Building tenants; (7) either the Transfer or any consideration payable to Landlord in connection therewith adversely affects the real
estate investment trust qualification tests applicable to Landlord or its Affiliates; or (8) the proposed transferee is or has been involved in litigation with Landlord or any of its Affiliates. Tenant shall not be entitled to receive monetary
damages based upon a claim that Landlord unreasonably withheld its consent to a proposed Transfer and Tenant’s sole remedy shall be an action to enforce any such provision through specific performance or declaratory judgment. Any attempted
Transfer in violation of this Article is voidable at Landlord’s option. 
  
 B. Consent Parameters/Requirements. As part of Tenant’s request for, and as a condition to, Landlord’s consent to a Transfer, Tenant shall provide Landlord with financial statements for the proposed
transferee, a complete copy (unexecuted) of the proposed assignment or sublease and other contractual documents, and such other information as Landlord may reasonably request. Landlord shall then have the right (but not the obligation) to terminate
this Lease as of the date the Transfer would have been effective (“Landlord Termination Date”) with respect to the portion of the Premises which Tenant desires to Transfer. In such event, Tenant shall vacate such portion of
the Premises by the Landlord Termination Date and upon Tenant’s vacating such portion of the Premises, the rent and other charges payable shall be proportionately reduced. Consent by Landlord to one or more Transfer(s) shall not operate as a
waiver of Landlord’s rights to approve any subsequent Transfers. In no event shall any Transfer or Permitted Transfer release or relieve Tenant from any obligation under this Lease, nor shall the acceptance of Rent from any assignee, subtenant
or occupant constitute a waiver or release of Tenant from any of its obligations or liabilities under this Lease. Tenant shall pay Landlord a review fee of $1000 for Landlord’s review of any Permitted Transfer or requested Transfer, provided if
Landlord’s actual reasonable costs and expenses (including reasonable attorney’s fees) exceed $1000, Tenant shall reimburse Landlord for its actual reasonable costs and expenses in lieu of a fixed review fee. 
  
 C. Payment to Landlord. If the aggregate consideration paid
to a Tenant Party for a Transfer exceeds that payable by Tenant under this Lease (prorated according to the transferred interest), Tenant shall pay Landlord 50% of such excess (after deducting therefrom reasonable leasing commissions and reasonable
costs of tenant improvements paid to unaffiliated third parties in connection with the Transfer, with proof of 

  

 12 








 
same provided to Landlord). Tenant shall pay Landlord for Landlord’s share of any excess within 30 days after Tenant’s receipt of such excess
consideration. If any uncured event of default exists under this Lease (or a condition exists which, with the passage of time or giving of notice, would become an event of default), Landlord may require that all sublease payments be made directly to
Landlord, in which case Tenant shall receive a credit against Rent in the amount of any payments received, but not to exceed the amount payable by Tenant under this Lease. 
  
 D. Change in Control of Tenant. Except for a Permitted Transfer, if Tenant is a corporation, limited
liability company, partnership, or similar entity, and if the entity which owns or controls a majority of the voting shares/rights in Tenant at any time sells or disposes of such majority of voting shares/rights, or changes Tenant’s identity
for any reason (including a merger, consolidation or reorganization), such change of ownership or control shall constitute a Transfer. The foregoing shall not apply so long as, both before and after the Transfer, Tenant is an entity whose
outstanding stock is listed on a recognized U.S. securities exchange, or if at least 80% of its voting stock is owned by another entity, the voting stock of which is so listed; provided, however, that Tenant shall give Landlord written notice at
least 30 days prior to the effective date of such change in ownership or control. 
  
 E. No Consent Required. Tenant may assign its entire interest under this Lease to its Affiliate (defined below) or to a successor to
Tenant by purchase, merger, consolidation or reorganization without the consent of Landlord, provided that all of the following conditions are satisfied in Landlord’s reasonable discretion (a “Permitted Transfer”):
(1) no uncured event of default exists under this Lease; (2) Tenant’s successor shall own all or substantially all of the assets of Tenant; (3) such Affiliate or successor shall have a net worth which is at least equal to the
greater of Tenant’s net worth at the date of this Lease or Tenant’s net worth as of the day prior to the proposed purchase, merger, consolidation or reorganization; (4) no portion of the Building or Premises would likely become
subject to additional or different Laws as a consequence of the proposed Transfer; (5) such Affiliate’s or successor’s use of the Premises shall not conflict with the Permitted Use or any exclusive usage rights granted to any other
tenant in the Building; (6) neither the Transfer nor any consideration payable to Landlord in connection therewith adversely affects the real estate investment trust qualification tests applicable to Landlord or its Affiliates; (7) such
Affiliate or successor is not and has not been involved in litigation with Landlord or any of Landlord’s Affiliates; and (8) Tenant shall give Landlord written notice at least 30 days prior to the effective date of the proposed Transfer,
along with all applicable documentation and other information necessary for Landlord to determine that the requirements of this Section 11.E have been satisfied, including if applicable, the qualification of such proposed transferee as
an Affiliate of Tenant. The term “Affiliate” means any person or entity controlling, controlled by or under common control with Tenant or Landlord, as applicable. If requested by Landlord, the Affiliate or successor shall
sign a commercially reasonable form of assumption agreement. 
  
 12. Liens. Tenant shall not permit mechanic’s or other liens to be placed upon the Property, Premises or Tenant’s leasehold interest in connection with any work or service done or purportedly done by or for the benefit of Tenant.
If a lien is so placed, Tenant shall, within 10 days of notice from Landlord of the filing of the lien, fully discharge the lien by settling the claim which resulted in the lien or by bonding or insuring over the lien in the manner prescribed by the
applicable lien Law. If Tenant fails to discharge the lien, then, in addition to any other right or remedy of Landlord, Landlord may bond or insure over the lien or otherwise discharge the lien. Tenant shall, within 30 days after receipt of an
invoice from Landlord, reimburse Landlord for any amount paid by Landlord, including reasonable attorneys’ fees, to bond or insure over the lien or discharge the lien. 
  
 13. Indemnity. Subject to Article 15 Tenant shall hold Landlord, its trustees, Affiliates, subsidiaries, members,
principals, beneficiaries, partners, officers, directors, shareholders, employees, Mortgagee(s) (defined in Article 25) and agents (including the manager of the Property) (collectively, “Landlord Parties”) harmless
from, and indemnify and defend such parties against, all liabilities, obligations, damages, penalties, claims, actions, costs, charges and expenses, including reasonable attorneys’ fees and other professional fees that may be imposed upon,
incurred by or asserted against any of such indemnified parties (each a “Claim” and collectively “Claims”) that arise out of or in connection with any damage or injury occurring in the Premises.
Provided 

  

 13 








 
Landlord Parties are properly named as additional insureds in the policies required to be carried under this Lease, and except as otherwise expressly
provided in this Lease, the indemnity set forth in the preceding sentence shall be limited to the greater of (A) $5,000,000, and (B) the aggregate amount of general/umbrella liability insurance actually carried by Tenant. Subject to
Articles 9.B, 15 and 20, Landlord shall hold Tenant, its trustees, members, principals, beneficiaries, partners, officers, directors, shareholders, employees and agents (collectively, “Tenant Parties”)
harmless from, and indemnify and defend such parties against, all Claims that arise out of or in connection with any damage or injury occurring in or on the Property (excluding the Premises), to the same extent the Tenant Parties would have been
covered had they been named as additional insureds on the commercial general liability insurance policy required to be carried by Landlord under this Lease. The indemnity set forth in the preceding sentence shall be limited to the amount of
$5,000,000. 
  
 14. Insurance 
  
 A. Tenant’s Insurance. Tenant shall maintain the
following insurance (“Tenant’s Insurance”), at its sole cost and expense: (1) commercial general liability insurance applicable to the Premises and its appurtenances providing, on an occurrence basis, a per
occurrence limit of no less than $1,000,000; (2) causes of loss-special form (formerly “all risk”) property insurance, including flood and earthquake, covering all above building standard leasehold improvements and Tenant’s trade
fixtures, equipment, furniture and other personal property within the Premises (“Tenant’s Property”) in the amount of the full replacement cost thereof; (3) business income (formerly “business
interruption”) insurance written on an actual loss sustained form or with sufficient limits to address reasonably anticipated business interruption losses; (4) business automobile liability insurance to cover all owned, hired and nonowned
automobiles owned or operated by Tenant providing a minimum combined single limit of $1,000,000; (5) workers’ compensation insurance as required by the state in which the Premises is located and in amounts as may be required by applicable
statute (provided, however, if no workers’ compensation insurance is statutorily required, Tenant shall carry workers’ compensation insurance in a minimum amount of $500,000); (6) employer’s liability insurance in an amount of at
least $500,000 per occurrence; and (7) umbrella liability insurance that follows form in excess of the limits specified in (1), (4) and (6) above, of no less than $4,000,000 per occurrence and in the aggregate. Any company
underwriting any of Tenant’s Insurance shall have, according to A.M. Best Insurance Guide, a Best’s rating of not less than A- and a Financial Size Category of not less than VIII. All commercial general liability, business
automobile liability and umbrella liability insurance policies shall name Landlord (or any successor), Landlord’s property manager, Landlord’s Mortgagee (if any), and their respective members, principals, beneficiaries, partners, officers,
directors, employees, and agents, and other designees of Landlord as the interest of such designees shall appear, as “additional insureds” and shall be primary with Landlord’s policy being secondary and noncontributory. If any
aggregate limit is reduced because of losses paid to below 75% of the limit required by this Lease, Tenant will notify Landlord in writing within 10 days of the date of reduction. All policies of Tenant’s Insurance shall contain endorsements
that the insurer(s) shall give Landlord and its designees at least 30 days’ advance written notice of any change, cancellation, termination or lapse of insurance. Tenant shall provide Landlord with a certificate of insurance and all required
endorsements evidencing Tenant’s Insurance prior to the earlier to occur of the Commencement Date or the date Tenant is provided access to the Premises for any reason, and upon renewals at least 10 days prior to the expiration of the insurance
coverage. All of Tenant’s Insurance policies, endorsements and certificates will be on forms and with deductibles and self-insured retention, if any, reasonably acceptable to Landlord. The limits of Tenant’s insurance shall not limit
Tenant’s liability under this Lease. 
  
 B.
Landlord’s Insurance. Landlord shall maintain: (1) commercial general liability insurance applicable to the Property which provides, on an occurrence basis, a minimum combined single limit of no less than $5,000,000 (coverage in excess of
$1,000,000 may be provided by way of an umbrella/excess liability policy); and (2) causes of loss-special form (formerly “all risk”) property insurance on the Building in the amount of the replacement cost thereof, as reasonably
estimated by Landlord. The foregoing insurance and any other insurance carried by Landlord may be effected by a policy or policies of blanket insurance and shall be for the sole benefit of Landlord and under Landlord’s sole control.
Consequently, Tenant shall have no right or claim to any proceeds thereof or any other rights thereunder. 
  

 14 








 15. Mutual Waiver of Subrogation. Notwithstanding anything in this Lease to the contrary, Tenant waives,
and shall cause its insurance carrier(s) and any other party claiming through or under such carrier(s), by way of subrogation or otherwise, to waive any and all rights of recovery, Claim, action or causes of action against all Landlord Parties for
any loss or damage to Tenant’s business, any loss of use of the Premises, and any loss, theft or damage to Tenant’s Property (including Tenant’s automobiles or the contents thereof), INCLUDING ALL
RIGHTS (BY WAY OF SUBROGATION OR OTHERWISE) OF RECOVERY, CLAIMS, ACTIONS
OR CAUSES OF ACTION ARISING OUT OF THE NEGLIGENCE OF ANY LANDLORD
PARTY, which loss or damage is (or would have been, had the insurance required by this Lease been maintained) covered by insurance. In addition, Landlord shall cause its insurance carrier(s) and any other party
claiming through or under such carrier(s), by way of subrogation or otherwise, to waive any and all rights of recovery, Claim, action or causes of action against all Tenant Parties for any loss of or damage to or loss of use of the Building, any
additions or improvements to the Building, or any contents thereof, INCLUDING ALL RIGHTS (BY WAY OF SUBROGATION OR
OTHERWISE) OF RECOVERY, CLAIMS, ACTIONS OR CAUSES OF ACTION ARISING OUT
OF THE NEGLIGENCE OF ANY TENANT PARTY, which loss or damage is (or would have been, had the insurance required by this Lease
been maintained) covered by insurance. 
  
 16. Casualty Damage.

  
 A. Repair or Termination bv Landlord. If all
or any part of the Premises are damaged by fire or other casualty, Tenant shall immediately notify Landlord in writing. Landlord shall have the right to terminate this Lease if: (1) the Building shall be damaged so that, in Landlord’s
judgment, substantial alteration or reconstruction of the Building shall be required (whether or not the Premises have been damaged); (2) Landlord is not permitted by Law to rebuild the Building in substantially the same form as existed before
the fire or casualty; (3) the Premises have been materially damaged and there is less than 2 years of the Term remaining on the date of the casualty; (4) any Mortgagee requires that the insurance proceeds be applied to the payment of the
mortgage debt; or (5) an uninsured loss of the Building occurs notwithstanding Landlord’s compliance with Section 14.B above, Landlord may exercise its right to terminate this Lease by notifying Tenant in writing within 90 days
after the date of the casualty. If Landlord does not terminate this Lease under this Section 16.A, Landlord shall commence and proceed with reasonable diligence to repair and restore the Building and/or the Premises to substantially the
same condition as existed immediately prior to the date of damage; provided, however, that Landlord shall only be required to reconstruct building standard leasehold improvements existing in the Premises as of the date of damage, and Tenant shall be
required to pay the cost for restoring any other leasehold improvements. However, in no event shall Landlord be required to spend more than the insurance proceeds received by Landlord. 
  
 B. Timing for Repair; Termination by Either Party. If all or any portion of the Premises is damaged as a
result of fire or other casualty, Landlord shall, with reasonable promptness, cause an architect or general contractor selected by Landlord to provide Landlord and Tenant with a written estimate of the amount of time required to substantially
complete the repair and restoration of the Premises, using standard working methods (“Completion Estimate”). If the Completion Estimate indicates that the Premises cannot be made tenantable within 270 days from the date of
damage, then regardless of anything in Section 16.A above to the contrary, either party shall have the right to terminate this Lease by giving written notice to the other of such election within 10 days after receipt of the Completion
Estimate. Tenant, however, shall not have the right to terminate this Lease if the fire or casualty was caused by the negligence or intentional misconduct of any of the Tenant Parties. If neither party terminates this Lease under this
Section 16.B, then Landlord shall repair and restore the Premises in accordance with, and subject to the limitations of, Section 16.A. 
  

C. Abatement. In the event a material portion of the Premises is damaged as a result of a fire or other casualty, the Base Rent shall
abate for the portion of the Premises that is damaged and not usable by Tenant until substantial completion of the repairs and restoration required to be made by Landlord pursuant to Section 16.A. Tenant, however, shall not be entitled
to such abatement if the fire or other casualty was caused by the negligence or intentional misconduct of any of the Tenant Parties. Landlord shall not be liable for any loss or damage to Tenant’s Property or to the business of Tenant resulting
in any way from the fire or other casualty or from the repair and restoration of the damage. Landlord and Tenant hereby waive the 

  

 15 








 
provisions of any Law relating to the matters addressed in this Article, and agree that their respective rights for damage to or destruction of the Premises
shall be those specifically provided in this Lease. 
  
 17.
Condemnation Either party may terminate this Lease if the whole or any material part of the Premises are taken or condemned for any public or quasi-public use under Law, by eminent domain or private purchase in lieu thereof (a
“Taking”). Landlord shall also have the right to terminate this Lease if there is a Taking of any portion of the Building or Property which would leave the remainder of the Building unsuitable for use as an office building in
a manner comparable to the Building’s use prior to the Taking. In order to exercise its right to terminate this Lease under this Article 17, Landlord or Tenant, as the case may be, must provide written notice of termination to the other
within 45 days after the terminating party first receives notice of the Taking. Any such termination shall be effective as of the date the physical taking of the Premises or the portion of the Building or Property occurs. If this Lease is not
terminated, the Rentable Square Footage of the Building, the Rentable Square Footage of the Premises and Tenant’s Pro Rata Share shall, if applicable, be appropriately adjusted by Landlord. In addition, Base Rent for any portion of the Premises
taken or condemned shall be abated during the unexpired Term effective when the physical taking of the portion of the Premises occurs. All compensation awarded for a Taking, or sale proceeds, shall be the property of Landlord, any right to receive
compensation or proceeds being expressly waived by Tenant. However, Tenant may file a separate claim at its sole cost and expense for Tenant’s Property (excluding above building standard leasehold improvements) and Tenant’s reasonable
relocation expenses, provided the filing of such claim does not diminish the award which would otherwise be receivable by Landlord. 
  
 18. Events of Default Tenant shall be considered to be in default under this Lease upon the occurrence of any of the following events of default:

  
 1. Tenant’s failure to pay when due all
or any portion of the Rent (“Monetary Default”); provided that the first 2 such failures during any consecutive 12 month period shall not be Monetary Defaults if Tenant pays the amount due within 5 days after written notice
from Landlord. 
  
 2. Tenant’s failure to
perform any of the obligations of Tenant in the manner set forth in Articles 14, 23, 24 or 25 (a “Time Sensitive Default”). 
  
 3. Tenant’s failure (other than a Monetary Default or a Time Sensitive Default) to comply with any
term, provision or covenant of this Lease, if the failure is not cured within 10 days after written notice to Tenant. However, if Tenant’s failure to comply cannot reasonably be cured within 10 days, Tenant shall be allowed additional time (not
to exceed an additional 10 days) as is reasonably necessary to cure the failure so long as: (1) Tenant commences to cure the failure within the 10 day period following Landlord’s initial written notice, and (2) Tenant diligently
pursues a course of action that will cure the failure and bring Tenant back into compliance with this Lease. However, if Tenant’s failure to comply creates a hazardous condition, the failure must be cured immediately upon notice to Tenant. In
addition, if Landlord provides Tenant with notice of Tenant’s failure to comply with the same specific term, provision or covenant of this Lease on more than two (2) occasions during any 12 month period, Tenant’s subsequent violation
of the same term, provision or covenant shall, at Landlord’s option, be deemed an incurable event of default by Tenant. 
  
 4. Tenant or any Guarantor becomes insolvent, files a petition for protection under the U.S. Bankruptcy Code (or similar Law) or a
petition is filed against Tenant or any Guarantor under such Laws and is not dismissed within 45 days after the date of such filing, makes a transfer in fraud of creditors or makes an assignment for the benefit of creditors, or admits in writing its
inability to pay its debts when due. 
  
 5. The
leasehold estate is taken by process or operation of Law. 
  
 6. In the case of any ground floor or retail tenant, or any other tenant whose space is visible from the Common Areas or elevator lobby areas of the Building, Tenant does not take possession of, or abandons or vacates
all or a substantial portion of the Premises. 
  
 7. Tenant is in default beyond any notice and cure period under any other lease or agreement with Landlord, including any lease or agreement for parking. 
  

 16 








 19. Remedies 
  
 A. Landlord’s Remedies Upon any default, Landlord shall have the right without notice or demand (except as provided in Article
18) to pursue any of its rights and remedies at Law or in equity, including any one or more of the following remedies: 
  
 1. Terminate this Lease; 
  
 2. Re-enter the Premises, change locks, alter security devices and lock out Tenant or terminate Tenant’s right of possession of the
Premises without terminating this Lease, and without complying with applicable Law, the benefits of which are waived by Tenant to the fullest extent permitted by applicable Law; 
  
 3. Remove and store, at Tenant’s expense, all the property in the Premises using such lawful force as
may be necessary; 
  
 4. Cure such event of
default for Tenant at Tenant’s expense (plus a 15% administrative fee); 
  
 5. Withhold or suspend payment of sums Landlord would otherwise be obligated to pay to Tenant under this Lease or any other agreement; 
  

 6. Require all future payments to be made by cashier’s check, money order or wire transfer after the first time any
check is returned for insufficient funds, or the second time any sum due hereunder is more than five (5) days late; 
  
 7. Apply any Security Deposit as permitted under this Lease; and/or 
  
 8. Recover such other amounts in addition to or in lieu of the foregoing as may be permitted from time to
time by applicable Law, including 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 events would be
likely to result therefrom. 
  
 B. Measure of
Damages; 
  
 1. Calculation. If Landlord
either terminates this Lease or terminates Tenant’s right to possession of the Premises, Tenant shall immediately surrender and vacate the Premises and pay Landlord on demand: (a) all Rent accrued through the end of the month in which the
termination becomes effective; (b) interest on all unpaid Rent from the date due at a rate equal to the lesser of 18% per annum or the highest interest rate permitted by applicable Law; (c) all expenses reasonably incurred by Landlord
in enforcing its rights and remedies under this Lease, including all reasonable legal expenses; (d) Costs of Reletting (defined below); and (e) all Landlord’s Rental Damages (defined below). In the event that Landlord relets the
Premises for an amount greater than the Rent due during the Term, Tenant shall not receive a credit for any such excess. 
  
 2. Definitions. “Costs of Reletting” shall include commercially reasonable costs, losses and expenses
incurred by Landlord in reletting all or any portion of the Premises including, without limitation, the cost of removing and storing Tenant’s furniture, trade fixtures, equipment, inventory or other property, repairing and/or demolishing the
Premises, removing and/or replacing Tenant’s signage and other fixtures, making the Premises ready for a new tenant, including the cost of advertising, commissions, architectural fees, legal fees and leasehold improvements, and any allowances
and/or concessions provided by Landlord. “Landlord’s Rental Damages” shall mean the total Rent which Landlord would have received under this Lease (had Tenant made all such Lease payments as required) for the remainder
of the Term minus the fair rental value of the Premises for the same period, or, if the Premises are relet, the actual rental value (not to exceed the Rent due during the Term), both discounted to present value at the Prime Rate (defined below) in
effect upon the date of determination. For purposes hereof, the “Prime Rate” shall be the per annum interest rate publicly announced by a federally insured bank selected by Landlord in the state in which the Building is
located as such bank’s prime or base rate. 
  

 17 








 3. Landlord’s Alternative Calculation. Because future market rental rates,
and the costs or time involved in reletting may be uncertain and difficult to determine at the time of Tenant’s default, the parties agree that Landlord may in its sole discretion elect to recover, in lieu of calculating damages under
Section 19.B(1)(d) and (e) above (but without limiting damages under Section 19.B(1)(a) and (b) above), the sum of (a) the unamortized portion of all costs, losses and expenses incurred by
Landlord as a result of entering into the Lease, and (b) twenty five percent (25%) of the total nominal Rent which Landlord would have received under this Lease (had Tenant made all such Rent payments as required) for the remainder of the
Term, which the parties agree is a fair and reasonable estimate of Landlord’s Rental Damages and the Costs of Reletting. 
  
 C. Tenant Not Relieved from Liabilities. Unless expressly provided in this Lease, the repossession or re-entering of all or any part of
the Premises shall not relieve Tenant of its liabilities and obligations under this Lease. In addition, Tenant shall not be relieved of its liabilities under this Lease, nor be entitled to any damages hereunder, based upon minor or immaterial errors
in the exercise of Landlord’s remedies. No right or remedy of Landlord shall be exclusive of any other right or remedy. Each right and remedy shall be cumulative and in addition to any other right and remedy now or subsequently available to
Landlord at Law or in equity. If Tenant fails to pay any amount when due hereunder (after the expiration of any applicable cure period), Landlord shall be entitled to receive interest on any unpaid item of Rent from the date initially due (without
regard to any applicable grace period) at a rate equal to the lesser of 18% per annum or the highest rate permitted by Law. In addition, if Tenant fails to pay any item or installment of Rent when due (after the expiration of any applicable
cure period), Tenant shall pay Landlord an administrative fee equal to 5% of the past due Rent. However, in no event shall the charges permitted under this Section 19.C or elsewhere in this Lease, to the extent they are considered
interest under applicable Law, exceed the maximum lawful rate of interest. If any payment by Tenant of an amount deemed to be interest results in Tenant having paid any interest in excess of that permitted by Law, then it is the express intent of
Landlord and Tenant that all such excess amounts theretofore collected by Landlord be credited against the other amounts owing by Tenant under this Lease. Receipt by Landlord of Tenant’s keys to the Premises shall not constitute an acceptance
or surrender of the Premises. NOTWITHSTANDING ANY OTHER PROVISION OF THIS LEASE TO THE CONTRARY,
TENANT SHALL HOLD LANDLORD PARTIES HARMLESS FROM AND INDEMNIFY AND DEFEND
SUCH PARTIES AGAINST, ALL CLAIMS THAT ARISE OUT OF OR IN CONNECTION
WITH A BREACH OF THIS LEASE, SPECIFICALLY INCLUDING ANY VIOLATION OF
APPLICABLE LAWS OR CONTAMINATION (DEFINED IN ARTICLE 30) CAUSED BY A TENANT
PARTY. 
  
 D.
Mitigation of Damages. Upon termination of Tenant’s right to possess the Premises, Landlord shall, only to the extent required by Law, use objectively reasonable efforts to mitigate damages by reletting the Premises. Landlord shall not be
deemed to have failed to do so if Landlord refuses to lease the Premises to a prospective new tenant with respect to whom Landlord would be entitled to withhold its consent pursuant to Section 11.A, or who (1) is an Affiliate,
parent or subsidiary of Tenant; (2) is not acceptable to any Mortgagee of Landlord; (3) requires improvements to the Premises to be made at Landlord’s expense; or (4) is unwilling to accept lease terms then proposed by Landlord,
including: (a) leasing for a shorter or longer term than remains under this Lease; (b) re-configuring or combining the Premises with other space; (c) taking all or only a part of the Premises; and/or (d) changing the use of the
Premises. Notwithstanding Landlord’s duty to mitigate its damages as provided herein, Landlord shall not be obligated (i) to give any priority to reletting Tenant’s space in connection with its leasing of space in the Building or any
complex of which the Building is a part, or (ii) to accept below market rental rates for the Premises or any rate that would negatively impact the market rates for the Building. To the extent that Landlord is required by applicable Law to
mitigate damages, Tenant must plead and prove by clear and convincing evidence that Landlord failed to so mitigate in accordance with the provisions of this Section 19.D, and that such failure resulted in an avoidable and quantifiable
detriment to Tenant. 
  
 E. Landlord’s Lien.
To secure Tenant’s obligations under this Lease, Tenant grants Landlord a contractual security interest on all of Tenant’s inventory, goods, consumer goods and equipment now or hereafter situated in the Premises and all proceeds therefrom,
including insurance proceeds (collectively, 

  

 18 








 
“Collateral”). No Collateral shall be removed from the Premises without Landlord’s prior written consent until all of
Tenant’s obligations are fully satisfied (except in the ordinary course of business and then only if replaced with items of same or greater value and quality). Upon any event of default, Landlord may, to the fullest extent permitted by Law and
in addition to any other remedies provided herein, enter upon the Premises and take possession of any Collateral without being held liable for trespass or conversion, and sell the same at public or private sale, after giving Tenant at least 10 days
written notice (or more if required by Law) of the time and place of such sale. Such notice may be sent with or without return receipt requested. Unless prohibited by Law, any Landlord Party may purchase any Collateral at such sale. Subject to
applicable Law, the proceeds from such sale, less Landlord’s expenses, including reasonable attorneys’ fees and other expenses, shall be credited against Tenant’s obligations. Any surplus shall be paid to Tenant (or as otherwise
required by Law) and any deficiency shall be paid by Tenant to Landlord upon demand. Tenant hereby authorizes Landlord to file a financing statement sufficient to perfect the foregoing security interest, or to file a copy of this Lease as a
financing statement, as permitted under Law. 
  
 20. Limitation of
Liability. Notwithstanding anything to the contrary contained in this Lease, the liability of Landlord (and of any successor Landlord) to Tenant (or any person or entity claiming by, through or under Tenant) shall be limited to the interest of
Landlord in the Property. Tenant shall look solely to Landlord’s interest in the Property for the recovery of any judgment or award against Landlord. No Landlord Party shall be personally liable for any judgment or deficiency. Before filing
suit for an alleged default by Landlord, Tenant shall give Landlord and the Mortgagee(s) (defined in Article 25) whom Tenant has been notified hold Mortgages (defined in Article 25) on the Property, Building or Premises, notice and
reasonable time to cure the alleged default. Tenant hereby waives all claims against all Landlord Parties for consequential, special or punitive damages allegedly suffered by any Tenant Parties, including lost profits and business interruption.

  
 21. No Waiver. Neither party’s failure to declare a
default immediately upon its occurrence or delay in taking action for a default shall constitute a waiver of the default, nor shall it constitute an estoppel. Neither party’s failure to enforce its rights for a default shall constitute a waiver
of that party’s rights regarding any subsequent default. 
  
 22. Tenant’s Right to Possession. Provided Tenant pays the Rent and fully performs all of its other covenants and agreements under this Lease, Tenant shall have the right to occupy the Premises without hindrance from Landlord or any
person lawfully claiming through Landlord, subject to the terms of this Lease, all Mortgages, insurance requirements and applicable Law. This covenant and all other covenants of Landlord shall be binding upon Landlord and its successors and
assignees only during its or their respective periods of ownership of the Building, and shall not be a personal covenant of any Landlord Parties. 
  
 23. Relocation. Landlord may, upon 90 days notice to Tenant, relocate the Premises to any other premises within the Property (“Relocated
Premises”) on a date of relocation (the “Relocation Date”) specified therein. The Relocated Premises shall in all respects be substantially the same or better, as reasonably determined by Landlord, in area,
finish, and appropriateness for the Permitted Use. In such event, all reasonable expenses of moving Tenant and decorating the Relocated Premises with substantially the same Ieasehold improvements shall be at the expense of Landlord, including the
physical move, relocating Tenant’s existing telephone equipment and other costs set forth below. All moving costs (including the cost to relocate phones, computers and other systems of similar nature), all costs of reprinting stationery, cards
and other printed material bearing Tenant’s address at the Premises if such address changes due to the relocation (but only the quantity existing immediately prior to the relocation) and all other out-of-pocket costs directly incurred by Tenant
in connection with relocation to the Relocated Premises, including reasonable decorating and design costs, shall be paid by Landlord within thirty (30) days after receipt of third-party invoices therefor. Tenant shall have the option, effective
as of the Relocation Date, either to enter into an appropriate lease amendment relocating the Premises, or to terminate this Lease, which option shall be exercised within 15 Business Days following receipt of Landlord’s relocation notice.
Failure of Tenant to choose either option within such period shall constitute Tenant’s election to relocate. If Tenant elects (or is deemed to have elected) to relocate, Landlord shall have the option to tender the Relocated 

  

 19 








 
Premises to Tenant on any date within a 30 day period prior to or after the Relocation Date, in which event the date of tender of possession of the Relocated
Premises shall become the Relocation Date. From the Relocation Date through the Expiration Date, the aggregate Base Rent for the Relocated Premises shall be the same as for the original Premises. Tenant’s failure to vacate the Premises and move
into the Relocated Premises on the Relocation Date shall constitute a Time Sensitive Default. 
  
 24. Holding Over. Except for any permitted occupancy by Tenant under Article 29, if Tenant or any party claiming by, through or under Tenant fails to surrender the Premises at the expiration or earlier
termination of this Lease, the continued occupancy of the Premises shall be that of a tenancy at sufferance. Tenant shall pay an amount (on a per month basis without reduction for partial months during the holdover) equal to 200% of the greater of:
(A) the sum of the Base Rent and Tenant’s Pro Rata Share of Excess Operating Expenses due for the period immediately preceding the holdover; or (B) the fair market gross rental for the Premises. Tenant shall otherwise continue to be
subject to all of Tenant’s obligations under this Lease. No holdover by Tenant or payment by Tenant after the expiration or early termination of this Lease shall be construed to extend the Term or prevent Landlord from immediate recovery of
possession of the Premises by summary proceedings or otherwise. In addition to the payment of the amounts provided above, if Landlord is unable to deliver possession of the Premises to a new tenant, or to perform improvements for a new tenant, as a
result of Tenant’s holdover and Tenant fails to vacate the Premises within 15 days after Landlord notifies Tenant of Landlord’s inability to deliver possession, or perform improvements, such failure shall constitute a Time Sensitive
Default hereunder; and notwithstanding any other provision of this Lease to the contrary, TENANT SHALL BE LIABLE TO LANDLORD FOR,
AND SHALL PROTECT LANDLORD FROM AND INDEMNIFY AND DEFEND LANDLORD AGAINST,
ALL LOSSES AND DAMAGES, INCLUDING ANY CLAIMS MADE BY ANY SUCCEEDING
TENANT RESULTING FROM SUCH FAILURE TO VACATE, AND ANY CONSEQUENTIAL DAMAGES
THAT LANDLORD SUFFERS FROM THE HOLDOVER. 
  
 25. Subordination to Mortgages; Estoppel Certificate. Tenant accepts this Lease subject and subordinate to any mortgage(s), deed(s) of trust, ground
lease(s) or other lien(s) now or subsequently affecting the Premises, the Building or the Property, and to renewals, modifications, refinancings and extensions thereof (collectively, a “Mortgage”). The party having the
benefit of a Mortgage shall be referred to as a “Mortgagee.” This clause shall be self-operative, but upon request from a Mortgagee, Tenant shall execute a commercially reasonable subordination agreement in favor of the
Mortgagee. In lieu of having the Mortgage be superior to this Lease, a Mortgagee shall have the right at any time to subordinate its Mortgage to this Lease. If requested by a successor-in-interest to all or a part of Landlord’s interest in this
Lease, Tenant shall, without charge, attorn to the successor-in-interest. Tenant shall, within 5 days after receipt of a written request from Landlord, execute and deliver an estoppel certificate to those parties as are reasonably requested by
Landlord (including a Mortgagee or prospective purchaser). The estoppel certificate shall include a statement certifying that this Lease is unmodified (except as identified in the estoppel certificate) and in full force and effect, describing the
dates to which Rent and other charges have been paid, representing that, to the best of Tenant’s knowledge, there is no default (or stating with specificity the nature of the alleged default) and certifying other matters with respect to this
Lease that may reasonably be requested. Tenant’s failure to provide any estoppel certificate within the 5 day period specified above, and the continuation of such failure for a period of 5 days after Landlord delivers a second written notice
requesting same, shall constitute a Time Sensitive Default under this Lease. 
  
 26. Attorneys’ Fees. If either party institutes a suit against the other for violation of or to enforce any covenant or condition of this Lease, or if either party intervenes in any suit in which the other is a
party to enforce or protect its interest or rights, the prevailing party shall be entitled to all of its costs and expenses, including reasonable attorneys’ fees. 
  

 27. Notice. If a demand, request, approval, consent or notice (collectively, a “notice”) shall or may be given to
either party by the other, the notice shall be in writing and delivered by hand or sent by registered or certified mail with return receipt requested, or sent by overnight or same day courier service, or sent by facsimile, at the party’s
respective Notice Address(es) set forth in Article 1, except that if Tenant has vacated the Premises (or if 

  

 20 








 
the Notice Address for Tenant is other than the Premises, and Tenant has vacated such address) without providing Landlord a new Notice Address, Landlord may
serve notice in any manner described in this Article or in any other manner permitted by Law. Each notice shall be deemed to have been received or given on the earlier to occur of actual delivery (which, in the case of delivery by facsimile, shall
be deemed to occur at the time of delivery indicated on the electronic confirmation of the facsimile) or the date on which delivery is first refused, or, if Tenant has vacated the Premises or the other Notice Address of Tenant without providing a
new Notice Address, three (3) days after notice is deposited in the U.S. mail or with a courier service in the manner described above. Either party may, at any time, change its Notice Address by giving the other party written notice of the new
address in the manner described in this Article. 
  
 28. Reserved
Rights. This Lease does not grant any rights to light or air over or about the Building. Landlord excepts and reserves exclusively to itself the use of: (A) roofs, (B) telephone, electrical and janitorial closets, (C) equipment rooms,
Building risers or similar areas that are used by Landlord for the provision of Building services, (D) rights to the land and improvements below the floor of the Premises, (E) the improvements and air rights above the Premises,
(F) the improvements and air rights outside the demising walls of the Premises, (G) the areas within the Premises used for the installation of utility lines and other installations serving occupants of the Building, and (H) any other
areas designated from time to time by Landlord as service areas of the Building. Tenant shall not have the right to install or operate any equipment producing radio frequencies, electrical or electromagnetic output or other signals, noise or
emissions in or from the Building without the prior written consent of Landlord. To the extent permitted by applicable Law, Landlord reserves the right to restrict and control the use of such equipment. Landlord has the right to change the
Building’s name or address. Landlord also has the right to make such other changes to the Property and Building as Landlord deems appropriate, provided the changes do not materially affect Tenant’s ability to use the Premises for the
Permitted Use. Landlord shall also have the right (but not the obligation) to temporarily close the Building if Landlord reasonably determines that there is an imminent danger of significant damage to the Building or of personal injury to
Landlord’s employees or the occupants of the Building. The circumstances under which Landlord may temporarily close the Building shall include, without limitation, electrical interruptions, hurricanes and civil disturbances. A closure of the
Building under such circumstances shall not constitute a constructive eviction nor entitle Tenant to an abatement or reduction of Rent. 
  
 29. Surrender of Premises. All improvements to the Premises (collectively, “Leasehold Improvements”) shall be owned by Landlord
and shall remain upon the Premises without compensation to Tenant. At the expiration or earlier termination of this Lease or Tenant’s right of possession, Tenant shall remove Tenant’s Removable Property (defined below) from the Premises,
and quit and surrender the Premises to Landlord, broom clean, and in good order, condition and repair, ordinary wear and tear excepted. As used herein, the term “Tenant’s Removable Property” shall mean: (A) Cable
installed by or for the benefit of Tenant and located in the Premises or other portions of the Building; (B) any Leasehold Improvements that are installed by or for the benefit of Tenant and, in Landlord’s reasonable judgment, are of a
nature that would require removal and repair costs that are materially in excess of the removal and repair costs associated with standard office improvements (“Special Installations”); and (C) Tenant’s personal
property. Notwithstanding the foregoing, Landlord may, in Landlord’s sole discretion and at no cost to Landlord, require Tenant to leave any of its Special Installations in the Premises. If Tenant fails to remove any of Tenant’s Removable
Property (other than Special Installations which Landlord has designated to remain in the Premises) within 2 days after the termination of this Lease or of Tenant’s right to possession, Landlord, at Tenant’s sole cost and expense, shall be
entitled (but not obligated) to remove and store Tenant’s Removable Property. Landlord shall not be responsible for the value, preservation or safekeeping of Tenant’s Removable Property. Tenant shall pay Landlord, upon demand, the expenses
and storage charges incurred for Tenant’s Removable Property. To the fullest extent permitted by applicable Law, any unused portion of Tenant’s Security Deposit may be applied to offset Landlord’s costs set forth in the preceding
sentence. In addition, if Tenant fails to remove Tenant’s Removable Property from the Premises or storage, as the case may be, within 30 days after written notice, Landlord may deem all or any part of Tenant’s Removable Property to be
abandoned, and title to Tenant’s Removable Property (except with respect to any Hazardous Material [defined in Article 30]) shall be deemed to be immediately vested in Landlord. Except for Special 

  

 21 








 
Installations designated by Landlord to remain in the Premises, Tenant’s Removable Property shall be removed by Tenant before the Expiration Date;
provided that upon Landlord’s prior written consent (which must be requested by Tenant at least 30 days in advance of the Expiration Date and which shall not be unreasonably withheld), Tenant may remain in the Premises for up to 5 days after
the Expiration Date for the sole purpose of removing Tenant’s Removable Property. Tenant’s possession of the Premises for such purpose shall be subject to all of the terms and conditions of this Lease, including the obligation to pay Base
Rent and Tenant’s Pro Rata Share of Excess Operating Expenses on a per diem basis at the rate in effect for the last month of the Term. In the event this Lease is terminated prior to the Expiration Date, Tenant’s Removable Property (except
for Special Installations designated by Landlord to remain in the Premises) shall be removed by Tenant on or before such earlier date of termination. Tenant shall repair damage caused by the installation or removal of Tenant’s Removable
Property. 
  
 30. Hazardous Materials. 
  
 A. Restrictions. No Hazardous Material (defined below)
(except for de minimis quantities of household cleaning products and office supplies used in the ordinary course of Tenant’s business at the Premises and that are used, kept and disposed of in compliance with Laws) shall be brought upon,
used, kept or disposed of in or about the Premises or the Property by any Tenant Parties or any of Tenant’s transferees, contractors or licensees without Landlord’s prior written consent, which consent may be withheld in Landlord’s
sole and absolute discretion. Tenant’s request for such consent shall include a representation and warranty by Tenant that the Hazardous Material in question (1) is necessary in the ordinary course of Tenant’s business, and
(2) shall be used, kept and disposed of in compliance with all Laws. 
  
 B. Remediation. Tenant shall, at its expense, monitor the Premises for the presence of Hazardous Materials or conditions which may reasonably give rise to Contamination (defined below) and promptly notify Landlord if
it suspects Contamination in the Premises. Any remediation of Contamination caused by a Tenant Party or its contractors or invitees which is required by Law or which is deemed necessary by Landlord, in Landlord’s opinion, shall be performed by
Landlord and Tenant shall reimburse Landlord for the cost thereof, plus a 15% administrative fee. 
  
 C. Definitions. For purposes of this Article 30, a “Hazardous Material” is any substance the presence of
which requires, or may hereafter require, notification, investigation or remediation under any Laws or which is now or hereafter defined, listed or regulated by any governmental authority as a “hazardous waste”, “extremely hazardous
waste”, “solid waste”, “toxic substance”, “hazardous substance”, “hazardous material” or “regulated substance”, or otherwise regulated under any Laws. “Contamination”
means the existence or any release or disposal of a Hazardous Material or biological or organic contaminant, including any such contaminant which could adversely impact air quality, such as mold, fungi or other bacterial agents, in, on, under, at or
from the Premises, the Building or the Property which may result in any liability, fine, use restriction, cost recovery lien, remediation requirement, or other government or private party action or imposition affecting any Landlord Party. For
purposes of this Lease, claims arising from Contamination shall include diminution in value, restrictions on use, adverse impact on leasing space, and all costs of site investigation, remediation, removal and restoration work, including response
costs under CERCLA and similar statutes. 
  
 D.
Reports, Surveys and Acceptance of Premises. All current surveys or reports prepared for the Property regarding the presence of Hazardous Materials (if any) in the Building are available for inspection by Tenant in the office of the Property
manager. With respect to Hazardous Materials, Tenant hereby (1) accepts full responsibility for reviewing any such surveys and reports and satisfying itself prior to the execution of this Lease as to the acceptability of the Premises under
Section 3.B above, and (2) acknowledges and agrees that this provision satisfies all notice requirements under applicable Law. In the event Tenant performs or causes to be performed any test on or within the Premises for the purpose
of determining the presence of a Hazardous Material, Tenant shall obtain Landlord’s prior written consent and use a vendor approved by Landlord for such testing. In addition, Tenant shall provide to Landlord a copy of such test within 10 days
of Tenant’s receipt. 
  

 22 








 31. Miscellaneous 
  
 A. Governing Law; Jurisdiction and Venue; Severability; Paragraph Headings. This Lease and the rights and
obligations of the parties shall be interpreted, construed and enforced in accordance with the Laws of the state in which the Property is located. All obligations under this Lease are performable in the county or other jurisdiction where the
Property is located, which shall be venue for all legal actions. If any term or provision of this Lease shall be invalid or unenforceable, then such term or provision shall be automatically reformed to the extent necessary to render such term or
provision enforceable, without the necessity of execution of any amendment or new document. The remainder of this Lease shall not be affected, and each remaining and reformed provision of this Lease shall be valid and enforced to the fullest extent
permitted by Law. The headings and titles to the Articles and Sections of this Lease are for convenience only and shall have no effect on the interpretation of any part of this Lease. The words “include”, “including” and similar
words will not be construed restrictively to limit or exclude other items not listed.

WORK LETTER 
  
 This Work Letter is attached as an Exhibit to an Office Lease (the “Lease”) between CRESCENT REAL ESTATE FUNDING VIII, L.P., as
Landlord, and CAMBRIDGE SILICON RADIO, INC., as Tenant, for the Premises, the Rentable Square Footage of which is 10,590, located on the tenth floor of the Building. Unless otherwise specified, all capitalized terms used in this Work Letter shall
have the same meanings as in the Lease. In the event of any conflict between the Lease and this Work Letter, the latter shall control. 
  
 1. Approved Construction Documents. 
  
 (A) Tenant’s Information. On or before December 5, 2004, Tenant shall submit to Landlord (i) the name of a
representative of Tenant who has been designated as the person responsible for receiving all information from and delivering all information to Landlord relating to the construction of the Landlord Work (as defined below), and (ii) all
information necessary for the preparation of complete, detailed architectural, mechanical, electrical and plumbing drawings and specifications for construction of the Landlord Work in the Premises, including Tenant’s partition and furniture
layout, reflected ceiling, telephone and electrical outlets and equipment rooms, initial provider(s) of telecommunications services, doors (including hardware and keying schedule), glass partitions, windows, critical dimensions, imposed loads on
structure, millwork, finish schedules, security devices, if any, which Tenant desires or Landlord requires to have integrated with other Building safety systems, and HVAC and electrical requirements (including Tenant’s connected electrical
loads and the National Electrical Code (NFPA-70) Design Load Calculations), together with all supporting information and delivery schedules (“Tenant’s Information”). 
  
 (B) Construction Documents. Following Landlord’s
execution of the Lease and receipt of Tenant’s Information, Landlord’s designated architectural/engineering firm shall prepare and submit to Tenant all finished and detailed architectural drawings and specifications, including mechanical,
electrical and plumbing drawings (the “Construction Documents”). In addition, Landlord shall advise Tenant of the number of days of Tenant Delay (as defined below) attributable to extraordinary requirements (if any) contained
in Tenant’s Information. Landlord (or its designated representative) reserves the right to designate the location(s) of all of Tenant’s mechanical, electrical or other equipment and the manner in which such equipment will be connected to
Building systems. 
  
 (C) Approved
Construction Documents. Within 3 Business Days after receipt, Tenant shall (i) approve and return the Construction Documents to Landlord, or (ii) provide Landlord Tenant’s written requested changes to the Construction Documents,
in which event Landlord shall have the Construction Documents revised (as Landlord deems appropriate) and resubmitted to Tenant for approval within 3 Business Days after receipt. If Tenant fails to request changes within such 3 Business Day period,
Tenant shall be deemed to have approved the Construction Documents. Upon Tenant’s approval, the Construction Documents shall become the “Approved Construction Documents.” By granting approval of the Construction
Documents (whether such approval is expressly granted or deemed given as provided above), Tenant shall be deemed to have confirmed by means of calculations or metering that the available capacity of the Building electrical system will support
Tenant’s electrical requirements. 
  
 2. Pricing and
Bids. Following receipt of the Approved Construction Documents, Landlord will promptly price the construction of the Landlord Work with approved general contractors in accordance with the Approved Construction Documents and furnish written
price estimates to Tenant. Upon receipt, Tenant shall promptly review such estimates and complete negotiations with Landlord for any changes or adjustments thereto. Within 5 Business Days after such receipt, Tenant shall return the estimates with
written approval to Landlord. If Tenant fails to give its approval within such 5 Business Day period, the lowest competent estimates will be deemed approved by Tenant. 
  


 D-i 








 3. Landlord’s Contributions. Landlord will provide a construction allowance not to
exceed $15.30 multiplied by the Rentable Square Footage of the Premises (the “Construction Allowance”), toward the cost of constructing the Landlord Work. Payments shall be made directly to Landlord’s contractor
performing the Landlord Work. The cost of (a) all space planning, design, consulting or review services and construction drawings, (b) extension of electrical wiring from Landlord’s designated location(s) to the Premises,
(c) purchasing and installing all building equipment for the Premises (including any submeters and other above building standard electrical equipment approved by Landlord), (d) required metering, re-circuiting or re-wring for metering,
equipment rental, engineering design services, consulting services, studies, construction services, cost of billing and collections, (e) materials and labor, and (f) an asbestos survey of the Premises if required by applicable Law, shall
all be included in the cost of the Landlord Work and may be paid out of the Construction Allowance, to the extent sufficient funds are available for such purpose. Tenant acknowledges that an asbestos survey will probably be required by applicable
Law and that the time required for such asbestos surveys should be incorporated in Tenant’s construction planning. Any remaining Construction Allowance may be applied toward the cost of converting up to 20 of Tenant’s unreserved parking
spaces described in Exhibit E attached hereto to covered parking spaces. The Construction Allowance made available to Tenant under this Work Letter must be utilized for its intended purpose within 180 days of the Effective Date or be
forfeited with no further obligation on the part of Landlord. 
  
 4. Construction. 
  
 (A)
General Terms. Subject to the terms of this Work Letter, Landlord agrees to cause leasehold improvements to be constructed in the Premises (the “Landlord Work”) in a good and workmanlike manner in accordance with the
Approved Construction Documents. Tenant acknowledges that Landlord is not an architect or engineer, and that the Landlord Work will be designed and performed by independent architects, engineers and contractors. Accordingly, Landlord does not
guarantee or warrant that the Approved Construction Documents will comply with Laws or be free from errors or omissions, nor that the Landlord Work will be free from defects, and Landlord will have no liability therefor. In the event of such errors,
omissions or defects, and upon Tenant’s written request, Landlord will use commercially reasonable efforts to cooperate with Tenant in enforcing any applicable warranties. In addition, Landlord’s approval of the Construction Documents or
the Landlord Work shall not be interpreted to waive or otherwise modify the terms and provisions of the Lease. Except with respect to the economic terms set forth in Paragraph 3 of this Work Letter, the terms and provisions contained in this
Work Letter shall survive the completion of the Landlord Work and shall govern in all applicable circumstances arising under the Lease throughout the term of the Lease, including the construction of future improvements in the Premises. Tenant
acknowledges that Tenant’s Information and the Approved Construction Documents must comply with (i) the definitions used by Landlord for the electrical terms used in this Work Letter, (ii) the electrical and HVAC design capacities of
the Building, (iii) Landlord’s policies concerning communications and fire alarm services, and (iv) Landlord’s policies concerning Tenant’s electrical design parameters, including harmonic distortion. Upon Tenant’s
request, Landlord will provide Tenant a written statement outlining items (i) through (iv) above. 
  
 (B) ADA Compliance. Landlord shall, as an Operating Expense, be responsible for ADA (and any applicable state accessibility
standard) compliance for the core areas of the Building (including elevators, Common Areas, and service areas), the Property’s parking facilities and all points of access into the Property. Tenant shall, at its expense, be responsible for ADA
(and any applicable state accessibility standard) compliance in the Premises, including restroorns on any floor now or hereafter leased or occupied in its entirety by Tenant, its Affiliates or transferees. Landlord shall not be responsible for
determining whether Tenant is a public accommodation under ADA or whether the Approved Construction Documents comply with ADA requirements, including submission of the Approved Construction Documents for review by appropriate state agencies. Such
determinations, if desired by Tenant, shall be the sole responsibility of Tenant.

 (C) Substantial Completion. The Landlord Work shall be deemed to be
“Substantially Complete” on the date that all Landlord Work (other than any details of construction, mechanical adjustment or any other similar matter, the noncompletion of which does not materially interfere with
Tenant’s use or occupancy of the Premises) has been performed. Time is of the essence in connection with the obligations of Landlord and Tenant under this Work Letter. Landlord shall not be liable or responsible for any claims incurred (or
alleged) by Tenant due to any delay in achieving Substantial Completion for any reason. Tenant’s sole and exclusive remedy for any delay in achieving Substantial Completion for any reason other than Tenant Delay (defined below) shall be the
resulting postponement (if any) of the commencement of rental payments under the Lease. “Tenant Delay” means any act or omission of Tenant or its agents, employees, vendors or contractors that actually delays the Substantial
Completion of the Landlord Work, including: (i) Tenant’s failure to furnish information or approvals within any time period specified in this Lease, including the failure to prepare or approve preliminary or final plans by any applicable
due date; (ii) Tenant’s selection of non-building standard equipment or materials; (iii) changes requested or made by Tenant to previously approved plans and specifications; or (iv) activities or performance of work in the
Premises by Tenant or Tenant’s contractor(s) during the performance of the Landlord Work. 
  
 5. Costs. 
  
 (A) Change Orders and Cost Overruns. Landlord’s approval is required in advance of all changes to, and deviations from, the Approved Construction Documents (each, a “Change Order”),
including any (i) omission, removal, alteration or other modification of any portion of the Landlord Work, (ii) additional architectural or engineering services, (iii) changes to materials, whether building standard materials,
specially ordered materials, or specially fabricated materials, or (iv) cancellation or modification of supply or fabrication orders. Except as otherwise expressly provided in this Work Letter, all costs of the Landlord Work in excess of the
Construction Allowance including Change Orders requested by Tenant and approved by Landlord which increase the cost of the Landlord Work (collectively, “Cost Overruns”) shall be paid by Tenant to Landlord within 10 days of
receipt of Landlord’s invoice. In addition, at Landlord’s election, Landlord may require Tenant to prepay any projected Cost Overruns within 10 days of receipt of Landlord’s invoice for same, Landlord may stop or decline to commence
all or any portion of the Landlord Work until such payment (or prepayment) of Cost Overruns is received. On or before the Commencement Date, and as a condition to Tenant’s right to take possession of the Premises, Tenant shall pay Landlord the
entire amount of all Cost Overruns, less any prepaid amounts. Tenant’s failure to pay, when due, any Cost Overruns or the cost of any Change Order shall constitute an event of default under the Lease. 
  
 (B) Construction Management Fee. Within 10 days
following the date of invoice, Tenant shall, for supervision and administration of the construction and installation of the Landlord Work, pay Landlord a construction management fee equal to 3% of the aggregate contract price for the Landlord Work,
which may be paid from the unused portion of the Construction Allowance (if any). Tenant’s failure to pay such construction management fee when due shall constitute an event of default under the Lease. 
  
 6. Acceptance. By taking possession of the Premises, Tenant
agrees and acknowledges that (i) the Premises are usable by Tenant as intended; (ii) Landlord has no further obligation to perform any Landlord Work or other construction (except punchlist items, if any agreed upon by Landlord and Tenant
in writing): and (iii) both the Building and the Premises are satisfactory in all respects.

PARKING AGREEMENT 
  
 This Parking Agreement (the “Agreement”) is attached as an Exhibit to an Office Lease (the “Lease”)
between CRESCENT REAL ESTATE FUNDING VIII, L.P., as Landlord, and CAMBRIDGE SILICON RADIO, INC., as Tenant, for the Premises, the Rentable Square Footage of which is 10,590, located on the tenth floor of the Building. Unless otherwise specified, all
capitalized terms used in this Agreement shall have the same meanings as in the Lease. 
  
 1. As of the Commencement Date of the Lease, Tenant shall have the right to use 46 permits allowing access to unreserved spaces in parking facilities which Landlord provides for the use of tenants and occupants of the
Building (the “Parking Facilities”), free of charge during the initial Term. During any renewal or extension of the Term, Tenant shall pay Landlord’s quoted monthly contract rate (as set from time to time) for each
unreserved permit, plus any taxes thereon. Tenant shall have the right to cause Landlord to convert up to 20 of Tenant’s unreserved spaces described above to covered parking spaces, at Tenant’s sole cost and expense, which expense may be
paid out of the Construction Allowance to the extent sufficient funds are available. Tenant shall pay $30.00 per month (plus any taxes thereon), for each covered parking space throughout the initial Term. During any renewal or extension of the Term,
Tenant shall pay Landlord’s quoted monthly contract rate (as set from time to time) for each covered parking space, plus any taxes thereon. 
  
 2. Tenant shall at all times comply with all Laws respecting the use of the Parking Facilities. Landlord reserves the right to adopt, modify, and enforce
reasonable rules and regulations governing the use of the Parking Facilities or the Property, from time to time, including any key-card, sticker, or other identification or entrance systems and hours of operations. Landlord may refuse to permit any
person who violates such rules and regulations to park in the Parking Facilities, and any violation of the rules and regulations shall subject the automobile in question to removal from the Parking Facilities. 
  
 3. Tenant may validate visitor parking by such method or methods as Landlord
may approve, at the validation rate (as set from time to time) generally applicable to visitor parking. Unless specified to the contrary above, the parking spaces for the parking permits provided hereunder shall be provided on an unreserved,
“first-come, first-served” basis. Tenant acknowledges that Landlord has arranged or may arrange for the Parking Facilities to be operated by an independent contractor, unaffiliated with Landlord. In such event, Tenant acknowledges that
Landlord shall have no liability for claims arising through acts or omissions of such independent contractor. Landlord shall have no liability whatsoever for any damage to vehicles or any other items located in or about the Parking Facilities, and
in all events, Tenant agrees to seek recovery from its insurance carrier and to require Tenant’s employees to seek recovery from their respective insurance carriers for payment of any property damage sustained in connection with any use of the
Parking Facilities. Landlord reserves the right to assign specific parking spaces, and to reserve parking spaces for visitors, small cars, handicapped persons and for other tenants, guests of tenants.or other parties, with assigned and/or reserved
spaces. Such reserved spaces may be relocated as determined by Landlord from time to time, and Tenant and persons designated by Tenant hereunder shall not park in any such assigned or reserved parking spaces. Landlord also reserves the right to
close all or any portion of the Parking Facilities, at its discretion or if required by casualty, strike, condemnation, repair, alteration, act of God, Laws, or other reason beyond Landlord’s reasonable control; provided, however, that except
for matters beyond Landlord’s reasonable control, any such closure shall be temporary in nature. If Tenant’s use of any parking permit is precluded for any reason, Tenant’s sole remedy for any period during which Tenant’s use of
any parking permit is precluded shall be abatement of parking charges for such precluded permits. Tenant shall not assign its rights under this Agreement except in connection with a Permitted Transfer. 
  
 4. Tenant’s failure to pay for any of the above-referenced parking
permits or to otherwise comply with any provision of this Agreement shall constitute an event of default under the Lease. In addition to any rights or remedies available to Landlord in the event of a Monetary Default under the Lease, Landlord shall
have the right to cancel this Agreement and/or remove any vehicles from the Parking Facilities.

 FIRST AMENDMENT TO OFFICE LEASE 
  
 THIS FIRST AMENDMENT TO OFFICE LEASE (this “First
Amendment”) is entered into as of the          day of             , 2006 (the “Effective Date”) by and between CRESCENT
REAL ESTATE FUNDING VIII, L.P., a Delaware limited partnership (“Landlord”), and CAMBRIDGE SILICON RADIO, INC., a Delaware corporation (“Tenant”). 
  
 RECITALS: 
  
 A. Landlord and Tenant executed that certain Office Lease dated December 20, 2004 (the “Lease”),
covering certain space therein designated as Suite 1000, the Rentable Square Footage of which is 10,590 square feet (the “Current Premises”), located on the 10th floor of an office building commonly known as Palisades Central I, and
located at 2425 North Central Expressway, Richardson, Dallas County, Texas (the “Building”). Unless otherwise expressly provided herein, capitalized terms used herein shall have the same meanings as designated in the Lease.

  
 B. Landlord and Tenant desire to amend and modify the Lease in
certain respects as provided herein. 
  
 AGREEMENT: 

  
 In consideration of the sum of Ten Dollars ($10.00), the
mutual covenants and agreements contained herein and in the Lease, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant hereby amend and modify the Lease as follows:

  
 32. Term. The Lease currently provides that the Term
expires on April 30, 2011. Section 1.G of the Lease is hereby modified and amended to provide that the Term is extended for an additional period of time, commencing on May 1, 2011 and continuing through and including the date
which is 60 full calendar months from the Expansion Space Commencement Date (defined below) (the “Expiration Date”), subject to earlier termination as provided in the Lease, as modified by this First Amendment. 
  
 33. Premises. The Lease is hereby modified and amended, effective as
of the Expansion Space Commencement Date, to include Suite 1050, the Rentable Square Footage of which is 8,238 square feet, located on the 10th floor of the Building (the “Expansion Space”), as shown on Exhibit A attached
hereto. The “Expansion Space Commencement Date” shall mean the earliest of (i) the date on which the Expansion Space Work (defined in the Work Letter attached hereto as Exhibit B) is Substantially Complete, as determined
pursuant to the Work Letter, or (ii) the date on which the Expansion Space Work would have been Substantially Complete but for Tenant Delay, as such term is defined in the Work Letter, or (iii) the date Tenant takes possession of any part
of the Expansion Space for purposes of conducting business. If Landlord is delayed in delivering possession of the Expansion Space due to any reason, including the holdover or unlawful possession of such space by any third party, such delay shall
not be a default by Landlord, render the Lease or this First Amendment void or voidable, or otherwise render Landlord liable for damages. From and after the Expansion Space Commencement Date and continuing throughout the remainder of the Term (as
extended hereby), the term “Premises” wherever used in the Lease or in this First Amendment shall mean the Current Premises, together with the Expansion Space, the collective Rentable Square Footage of which is 18,828 square feet.
Tenant hereby acknowledges that the Expansion Space is leased by Tenant subject to all terms and conditions of the Lease, as modified by this First Amendment. 
  

34. Base Rent. Effective as of the Expansion Space Commencement Date and continuing through the Expiration Date, the Base Rent due and payable
for the Expansion Space shall be $152,403.00 per annum, payable in equal monthly installments of $12,700.25, calculated based on an annual rate of $18.50 multiplied by the Rentable Square Footage of the Expansion Space. Effective as of May 1,
2011 and continuing through the Expiration Date, the Base Rent due and payable for the Current Premises shall be $195,915.00 per annum, 








 
payable in equal monthly installments of $l6,326.25, calculated based on an annual rate of $18.50 multiplied by the Rentable Square Footage of the Current
Premises. Base Rent for any partial month shall be prorated on a daily basis. The Base Rent for the Expansion Space shall be paid in addition to the Base Rent for the Current Premises and all Rent shall be payable in accordance with the terms and
provisions of the Lease, as modified by this First Amendment. 
  
 35. Tenant’s Pro Rata Share. Effective as of the Expansion Space Commencement Date, Tenant’s Pro Rata Share shall be adjusted to include the Rentable Square Footage of the Expansion Space. 
  
 36. Base Year. Effective as of the Expansion Space Commencement Date,
Section 1.F of the Lease is hereby modified and amended to provide that with respect to the Expansion Space only, the Base Year shall be the calendar year 2006. 
  
 37. Condition of Expansion Space. TENANT ACCEPTS THE
EXPANSION SPACE IN ITS “AS IS” CONDITION, AND LANDLORD MAKES NO
REPRESENTATIONS OR WARRANTIES WHATSOEVER WITH RESPECT THERETO. However, provided no event of default has occurred, Landlord agrees to construct,
or cause to be constructed, leasehold improvements in and upon the Expansion Space in accordance with the Work Letter attached hereto as Exhibit B. 
  
 38. Parking. Effective as of the Expansion Space Commencement Date and continuing throughout the remainder of the Term, Tenant shall have the right
to lease 35 additional unreserved parking spaces in the Parking Facilities. Notwithstanding anything to the contrary contained in the foregoing, Tenant shall have the right to use the additional 35 unreserved parking spaces free of charge during the
initial Term. During any renewal or extension of the Term, Tenant shall pay Landlord’s quoted monthly contract rate (as set from time to time) for each unreserved permit, plus any taxes thereon. Tenant shall use such parking spaces in
accordance with the terms and conditions of Exhibit E attached to the Lease. 
  
 39. No Broker. Tenant represents that it has not dealt with any broker or agent in connection with this First Amendment. TENANT SHALL INDEMNIFY AND
DEFEND EACH LANDLORD PARTY AGAINST ANY CLAIMS FOR REAL ESTATE COMMISSIONS
OR FEES IN CONNECTION WITH THIS FIRST AMENDMENT MADE BY ANY PARTY
CLAIMING THROUGH TENANT. 
  
 40. Time of the Essence. Time is of the essence with respect to Tenant’s execution and delivery of this First Amendment to Landlord. If Tenant fails to execute and deliver a signed copy of this First Amendment to Landlord by
5:00 p.m. (Richardson, Texas time), on March 31, 2006, it shall be deemed null and void and shall have no force or effect, unless otherwise agreed in writing by Landlord. Landlord’s acceptance, execution and return of this document shall
constitute Landlord’s agreement to waive Tenant’s failure to meet the foregoing deadline. 
  
 41. Miscellaneous. This First Amendment shall become effective only upon full execution and delivery of this First Amendment by Landlord and
Tenant. This First Amendment contains the parties’ entire agreement regarding the subject matter covered by this First Amendment, and supersedes all prior correspondence, negotiations, and agreements, if any, whether oral or written, between
the parties concerning such subject matter. There are no contemporaneous oral agreements, and there are no representations or warranties between the parties not contained in this First Amendment. Except as modified by this First Amendment, the terms
and provisions of the Lease shall remain in full force and effect, and the Lease, as modified by this First Amendment, shall be binding upon and shall inure to the benefit of the parties hereto, their successors and permitted assigns. 
  
 42. Ratification. Tenant hereby ratifies and confirms its obligations
under the Lease and represents and warrants to Landlord that it has no defenses thereto. Additionally, Tenant further confirms and ratifies that, as of the date hereof, (a) the Lease is and remains in good standing and full force and effect,
and (b) Tenant has no claims, counterclaims, set-offs or defenses against Landlord arising out of the Lease or in any way relating thereto or arising out of any other transaction between Landlord and Tenant.

WORK LETTER 
  
 This Work Letter is attached as an Exhibit to a First Amendment to Office Lease (the “First Amendment”) between CRESCENT REAL ESTATE
FUNDING VIII, L.P., as Landlord, and CAMBRIDGE SILICON RADIO, INC., as Tenant. Unless otherwise specified, all capitalized terms used in this Work Letter shall have the same meanings as in the Lease, as modified by the First Amendment. In the event
of any conflict between the Lease, as modified by the First Amendment, and this Work Letter, the latter shall control. 
  
 1. Approved Construction Documents. 
  
 (A) Tenant’s Information. On or before April 7, 2006, Tenant shall submit to Landlord (i) the name of a
representative of Tenant who has been designated as the person responsible for receiving all information from and delivering all information to Landlord relating to the construction of the Expansion Space Work (as defined below), and (ii) all
information necessary for the preparation of complete, detailed architectural, mechanical, electrical and plumbing drawings and specifications for construction of the Expansion Space Work in the Expansion Space, including Tenant’s partition and
furniture layout, reflected ceiling, telephone and electrical outlets and equipment rooms, initial provider(s) of telecommunications services, doors (including hardware and keying schedule), glass partitions, windows, critical dimensions, imposed
loads on structure, millwork, finish schedules, security devices, if any, which Tenant desires or Landlord requires to have integrated with other Building safety systems, and HVAC and electrical requirements (including Tenant’s connected
electrical loads and the National Electrical Code (NFPA-70) Design Load Calculations), together with all supporting information and delivery schedules (“Tenant’s Information”). 
  
 (B) Construction Documents. Following Landlord’s
execution of the First Amendment and receipt of Tenant’s Information, Landlord’s designated architectural/engineering firm shall prepare and submit to Tenant all finished and detailed architectural drawings and specifications, including
mechanical, electrical and plumbing drawings (the “Construction Documents”). In addition, Landlord shall advise Tenant of the number of days of Tenant Delay (as defined below) attributable to extraordinary requirements (if any)
contained in Tenant’s Information. Landlord (or its designated representative) reserves the right to designate the location(s) of all of Tenant’s mechanical, electrical or other equipment and the manner in which such equipment will be
connected to Building systems. 
  
 (C)
Approved Construction Documents. Within 3 Business Days after receipt, Tenant shall (i) approve and return the Construction Documents to Landlord, or (ii) provide Landlord Tenant’s written requested changes to the Construction
Documents, in which event Landlord shall have the Construction Documents revised (as Landlord deems appropriate) and resubmitted to Tenant for approval within 3 Business Days after receipt. If Tenant fails to request changes within such 3 Business
Day period, Tenant shall be deemed to have approved the Construction Documents. Upon Tenant’s approval, the Construction Documents shall become the “Approved Construction Documents”. By granting approval of the Construction
Documents (whether such approval is expressly granted or deemed given as provided above), Tenant shall be deemed to have confirmed by means of calculations or metering that the available capacity of the Building electrical system will support
Tenant’s electrical requirements. 
  
 2. Pricing and
Bids. Following receipt of the Approved Construction Documents, Landlord will promptly price the construction of the Expansion Space Work with approved general contractors in accordance with the Approved Construction Documents and furnish
written price estimates to Tenant. Upon receipt, Tenant shall promptly review such estimates and complete negotiations with Landlord for any changes or adjustments thereto. Within 5 Business Days after such receipt, Tenant shall return the
estimates with written approval to Landlord. If Tenant fails to give its approval within such 5 Business Day period, the lowest competent estimates will be deemed approved by Tenant. 
  

 B-i 








 3. Landlord’s Contributions. Landlord will provide a construction allowance not to exceed
$20.00 multiplied by the Rentable Square Footage of the Expansion Space (the “Construction Allowance”), toward the cost of constructing the Expansion Space Work. Payments shall be made directly to Landlord’s contractor
performing the Expansion Space Work. The cost of (a) all space planning, design, consulting or review services and construction drawings, (b) extension of electrical wiring from Landlord’s designated location(s) to the Expansion
Space, (c) purchasing and installing all building equipment for the Expansion Space (including any submeters and other above building standard electrical equipment approved by Landlord), (d) required metering, re-circuiting or rewiring for
metering, equipment rental, engineering design services, consulting services, studies, construction services, cost of billing and collections, (e) materials and labor, and (f) an asbestos survey of the Expansion Space if required by
applicable Law, shall all be included in the cost of the Expansion Space Work and may be paid out of the Construction Allowance, to the extent sufficient funds are available for such purpose. Tenant acknowledges that an asbestos survey will probably
be required by applicable Law and that the time required for such asbestos surveys should be incorporated in Tenant’s construction planning. The Construction Allowance made available to Tenant under this Work Letter must be utilized for its
intended purpose within 180 days of the Effective Date of the First Amendment or be forfeited with no further obligation on the part of Landlord. 
  
 4. Special Leasehold Allowance. At Tenant’s election, Landlord shall contribute an additional sum not to exceed $3.00 multiplied by the
Rentable Square Footage of the Expansion Space (the “Special Leasehold Allowance”) toward additional permanent leasehold improvements Tenant elects to install in the Expansion Space. The amount of the Special Leasehold Allowance
actually utilized by Tenant shall be amortized as additional Base Rent for the Expansion Space over the Term at 8% per annum, in the same manner as a loan having equal monthly payments of principal and interest. Tenant’s election to use
all or a portion of the Special Leasehold Allowance shall be made by written notice to Landlord given no later than 5 days after Substantial Completion (defined below). Within 10 days after Landlord’s request, Tenant shall execute and return an
amendment modifying the Base Rent for the Expansion Space accordingly. If Tenant fails timely (i) to make its election regarding utilization of the Special Leasehold Allowance or (ii) to execute and return the required lease amendment,
then Landlord shall automatically be released from its obligation to contribute the Special Leasehold Allowance, whereupon Tenant shall promptly pay Landlord the full amount of any Cost Overruns in accordance with Paragraph 6. If, for any
reason, less than all of the Term remains at the time the required lease amendment is executed and returned to Landlord, then Tenant shall, upon demand, promptly pay all amortization payments (including interest) which would have been payable for
the elapsed portion of the Term through the month in which such lease amendment is actually so executed and returned. Any failure by Tenant to make any payments required under the foregoing provisions shall constitute a material event of default
under the Lease, as modified by the First Amendment. 
  
 5.
Construction. 
  
 (A) General
Terms. Subject to the terms of this Work Letter, Landlord agrees to cause leasehold improvements to be constructed in the Expansion Space (the “Expansion Space Work”) in a good and workmanlike manner in accordance with the
Approved Construction Documents. Tenant acknowledges that Landlord is not an architect or engineer, and that the Expansion Space Work will be designed and performed by independent architects, engineers and contractors. Accordingly, Landlord does not
guarantee or warrant that the Approved Construction Documents will comply with Laws or be free from errors or omissions, nor that the Expansion Space Work will be free from defects, and Landlord will have no liability therefor. In the event of such
errors, omissions or defects, and upon Tenant’s written request, Landlord will use commercially reasonable efforts to cooperate with Tenant in enforcing any applicable warranties. In addition, Landlord’s approval of the Construction
Documents or the Expansion Space Work shall not be interpreted to waive or otherwise modify the terms and provisions of the Lease, as modified by the First Amendment. Except with respect to the economic terms set forth in Paragraph 3 of this
Work Letter, the terms and provisions contained in this Work Letter shall survive the completion of the Expansion Space Work and shall govern in all applicable circumstances arising under the Lease, as modified by the First 

  

 B-ii 








 
Amendment, throughout the Term, including the construction of future improvements in the Expansion Space. Tenant acknowledges that Tenant’s Information
and the Approved Construction Documents must comply with (i) the definitions used by Landlord for the electrical terms used in this Work Letter, (ii) the electrical and HVAC design capacities of the Building, (iii) Landlord’s
policies concerning communications and fire alarm services, and (iv) Landlord’s policies concerning Tenant’s electrical design parameters, including harmonic distortion. Upon Tenant’s request, Landlord will provide Tenant a
written statement outlining items (i) through (iv) above. 
  
 (B) ADA Compliance. Landlord shall, as an Operating Expense, be responsible for ADA (and any applicable state accessibility standard) compliance for the core areas of the Building (including elevators, Common Areas, and service
areas), the Property’s parking facilities and all points of access into the Property. Tenant shall, at its expense, be responsible for ADA (and any applicable state accessibility standard) compliance in the Premises, including restrooms on any
floor now or hereafter leased or occupied in its entirety by Tenant, its Affiliates or transferees. Landlord shall not be responsible for determining whether Tenant is a public accommodation under ADA or whether the Approved Construction Documents
comply with ADA requirements, including submission of the Approved Construction Documents for review by appropriate state agencies. Such determinations, if desired by Tenant, shall be the sole responsibility of Tenant. 
  
 (C) Substantial Completion. The Expansion Space Work shall be deemed
to be “Substantially Complete” on the date that all Expansion Space Work (other than any details of construction, mechanical adjustment or any other similar matter, the noncompletion of which does not materially interfere with
Tenant’s use or occupancy of the Expansion Space) has been performed. Time is of the essence in connection with the obligations of Landlord and Tenant under this Work Letter. Landlord shall not be liable or responsible for any claims incurred
(or alleged) by Tenant due to any delay in achieving Substantial Completion for any reason. Tenant’s sole and exclusive remedy for any delay in achieving Substantial Completion for any reason other than Tenant Delay (defined below) shall be the
resulting postponement (if any) of the commencement of rental payments for the Expansion Space under the First Amendment. “Tenant Delay” means any act or omission of Tenant or its agents, employees, vendors or contractors that
actually delays the Substantial Completion of the Expansion Space Work, including: (i) Tenant’s failure to furnish information or approvals within any time period specified in the Lease, as modified by the First Amendment, including the
failure to prepare or approve preliminary or final plans by any applicable due date; (ii) Tenant’s selection of non-building standard equipment or materials; (iii) changes requested or made by Tenant to previously approved plans and
specifications; or (iv) performance of work in the Expansion Space by Tenant or Tenant’s contractor(s) during the performance of the Expansion Space Work. 
  
 6. Costs. 
  
 (A) Change Orders and Cost Overruns. Landlord’s approval is required in advance of all changes to, and deviations from, the
Approved Construction Documents (each, a “Change Order”), including any (i) omission, removal, alteration or other modification of any portion of the Expansion Space Work, (ii) additional architectural or engineering
services, (iii) changes to materials, whether building standard materials, specially ordered materials, or specially fabricated materials, or (iv) cancellation or modification of supply or fabrication orders. Except as otherwise expressly
provided in this Work Letter, all costs of the Expansion Space Work in excess of the Construction Allowance including Change Orders requested by Tenant and approved by Landlord which increase the cost of the Expansion Space Work (collectively,
“Cost Overruns”) shall be paid by Tenant to Landlord within 10 days of receipt of Landlord’s invoice. In addition, at Landlord’s election, Landlord may require Tenant to prepay any projected Cost Overruns within 10 days of
receipt of Landlord’s invoice for same. Landlord may stop or decline to commence all or any portion of the Expansion Space Work until such payment (or prepayment) of Cost Overruns is received. On or before the Expansion Space Commencement Date,
and as a condition to Tenant’s right to take possession of the Expansion Space, Tenant shall pay Landlord the entire amount of all Cost Overruns, less any prepaid amounts. Tenant’s failure to pay, when due, any Cost Overruns or the cost of
any Change Order shall constitute an event of default under the Lease, as modified by the First Amendment. 
  

 B-iii 








 (B) Construction Management Fee. Within 10 days following the date of invoice,
Tenant shall, for supervision and administration of the construction and installation of the Expansion Space Work, pay Landlord a construction management fee equal to 3% of the aggregate contract price for the Expansion Space Work, which may be paid
from the unused portion of the Construction Allowance (if any). Tenant’s failure to pay such construction management fee when due shall constitute an event of default under the Lease, as modified by the First Amendment. 
  
 7. Acceptance. By taking possession of the Expansion Space, Tenant
agrees and acknowledges that (i) the Expansion Space is usable by Tenant as intended; (ii) Landlord has no further obligation to perform any Expansion Space Work or other construction (except punchlist items, if any agreed upon by Landlord
and Tenant in writing): and (iii) the Building, the Current Premises and the Expansion Space are satisfactory in all respects. 
  

 B-iv
