2.9 Common Facilities. “Common Facilities” shall mean all of the Property except (a) the
Demised Premises and (b) the other premises in the Project leased or held for lease to other tenants. Common Facilities shall include the Parking Area and any walks and driveways. The Common Facilities may be augmented from time to time by
Landlord as it deems reasonable under the circumstances so long as any change does not materially impact Tenant’s access or use of the Premises. 
 2.10 Parking Area. “Parking Area” shall mean that portion of the Common Facilities which is or is to be paved and otherwise improved for the parking of motor
vehicles, as designated by Landlord from time to time in close proximity to the Building.

Tenant shall not unreasonably interfere, at any time, with the rights of Landlord and others entitled to use any part of the Common Facilities, and shall not store, either permanently or temporarily, any materials, supplies or equipment in or on the
Common Facilities. Landlord shall have the right, at any time, to change, reduce or otherwise alter the Common Facilities which may impact the Demised Premises, in its sole and subjective discretion and without compensation to Tenant,
provided, however, such change (a) does not impact Tenant’s ability to conduct its business at the Demised Premises, (b) does not materially change the view, or the perceived image of the Demised Premises, (c) does
not materially impact Tenant’s or visitors access to the Demised Premises, (d) does not increase any operating costs or Common Facility Charges (e) does not reduce services or accessibility of services, (f) does not reduce the

telecommunications and utilities chases, ducts or other passageways located within the Demised Premises, the Building or the Project (the “Reserved Area”). The installation of any telecommunications or utilities wires, cables
or other equipment or facilities in the Reserved Area by Tenant or any other service provider of Tenant shall be subject to the prior written approval of Landlord which shall not be unreasonably withheld, conditioned or delayed. Landlord shall be
entitled to allocate the available space in the Reserved Area as Landlord determines from time to time on a proportionate share based on the percent occupied by Tenant of the Building. If Landlord determines that Tenant’s use of the Reserved
Area shall require additional improvements or other costs to Landlord, Landlord shall be entitled to charge such unreasonable costs to Tenant as a condition precedent to its consent.

merchantability, express or implied, relating to the Demised Premises. Tenant’s acceptance of the Demised Premises shall constitute its acknowledgment that the Demised Premises was in good condition, order and repair at the time of such
acceptance including, without limitation, all doors, any loading dock doors, dock levelers, related dock systems and areas, and all other mechanical and electrical systems. 
 2.14 Relocation. [Intentionally deleted]. 
  

	III.	TERM OF LEASE. 

3.1 Initial Lease Term; Lease Term. “Initial Lease Term” shall mean the period of time specified in
the Summary commencing at noon on the Commencement Date specified in the Summary and expiring at noon on July 31, 2016 (the Initial Lease Term together with any extensions thereof is herein referred to as the “Lease
Term”). 
  

	IV.	RENT AND OTHER AMOUNTS PAYABLE. 

 4.1 Basic Rent. Tenant covenants and agrees to pay to Landlord, without offset, reduction, deduction, counterclaim or abatement (except as otherwise expressly set forth in this

  
 3 

 
Lease), basic rent for the Lease Term in the amount specified as basic rent in the Summary (“Basic Rent”). The term “year” and subsequent years as
described in the Summary shall mean: (a) as to the first year of the Lease Term, the period of time beginning on the Commencement Date of the Initial Lease Term and ending upon the last day of the calendar month falling on or after the first
anniversary of the Initial Lease Term; and (b) for subsequent years, the corresponding period of time commencing upon the expiration of the previous year and ending one (1) year thereafter. 

4.2 Monthly Payments. Basic Rent shall be payable monthly in advance, without notice, in equal installments in the amount
of monthly rent specified in the Summary. The first such monthly installment shall be due and payable upon the Effective Date and a like monthly installment shall be due and payable on or before the first day of each calendar month succeeding the
Commencement Date recited in the Summary during the Lease Term, except that the rental payment for any fractional calendar month at the commencement or end of the Lease Term shall be prorated based on a thirty (30) day month. Acceptance of
Basic Rent or any other sums payable by Tenant to Landlord from anyone other than Tenant shall not be construed as a waiver by Landlord, nor as a release of Tenant, but the same shall be taken to be a payment on account of Tenant. 

4.3 Place of Payments. Basic Rent and all other sums payable by Tenant to Landlord under this Lease shall be paid to
Landlord at the place for payments specified in the Summary, or such other place as Landlord may, from time to time but with not less than thirty (30) days prior notice to Tenant, designate in writing. 

4.4 Lease a Net Lease and Rent Absolute. It is the intent of the parties that the Basic Rent provided in this Lease shall
be a net payment to Landlord; that this Lease shall continue for the full Lease Term notwithstanding any occurrence preventing or restricting use and occupancy of the Demised Premises, including any damage or destruction affecting the Demised
Premises, and any action by governmental authority relating to or affecting the Demised Premises, except as otherwise specifically provided in this Lease; that the Basic Rent and Additional Rent shall be absolutely payable without offset, reduction,
deduction, counterclaim, or abatement for any cause except as otherwise specifically provided in this Lease; that Landlord shall not bear any costs or expenses relating to the Demised Premises or provide any services or do any act in connection with
the Demised Premises except as otherwise specifically provided in this Lease; and that Tenant shall pay, in addition to Basic Rent, Additional Rent to cover costs and expenses relating to the Demised Premises, the Common Facilities, and the
Property, all as hereinafter provided. 
 4.5 Additional Rent. Tenant covenants and agrees to pay, as additional
rent under this Lease (“Additional Rent”), without offset, reduction, deduction, counterclaim or abatement (except as otherwise expressly set forth in this Lease), all costs and expenses relating to the use, operation,
maintenance and repair of the Demised Premises by Tenant; Tenant’s Pro Rata Share (as defined in Section 4.6) of the Common Facilities Charges (as defined in Section 7.2): Tenant’s Pro Rata Share of all Taxes (as
defined in Section 5.1) and Landlord’s Insurance (as defined in Section 4.7); and all other costs and expenses which Tenant is obligated to pay to Landlord or any other person or entity under this Lease, whether or not
stated or characterized as Additional Rent. 

  
 4 

 4.6 Tenant’s Pro Rata Share. “Tenant’s Pro Rata
Share” shall mean the percentage set forth in the Summary as Tenant’s Pro Rata Share which is the percentage derived by dividing the Floor Area of the Demised Premises, as initially set forth in the Summary by the Floor Area of the
Building or the Project, as the case may be, as initially set forth in the Summary. Landlord and Tenant agree that such approximations of Floor Area of the Demised Premises, the Building and the Project are reasonable, and that the calculations of
Basic Rent and Tenant’s Pro Rata Share based on such approximations are not subject to revision under any circumstances, except as expressly provided in this Section 4.6. If the Floor Area of the Demised Premises, the Building, or
the Project are ever remeasured, the result may only be used to adjust the identification thereof, and neither Landlord nor Tenant shall be entitled to claim an increase or decrease in the amount of the monthly Basic Rent specified in the Summary or
the amount of Tenant’s Pro Rata Share specified in the Summary based upon such remeasurement. The Demised Premises shall be approximately as depicted in the Space Plan, provided, however, in no event shall Landlord be liable to Tenant or Tenant
have any claims or rights against Landlord if the actual Floor Area of the Demised Premises is different than the estimated Floor Area of the Demised Premises herein provided. Notwithstanding anything to the contrary, if Landlord from time to time
increases or reduces the Floor Area of the Building or constructs additional building(s) upon the Land or the Project, as the case may be, then Landlord shall recalculate Tenant’s Pro Rata Share using the formulas hereinabove set forth based
upon the added or reduced Floor Area. Landlord shall be entitled to provide services for the Common Facilities for either the Building or the Project, as Landlord reasonably determines from time to time or may be necessary consistent with comparable
services for Class A so-called “office flex” buildings (built after 1998). Landlord shall be entitled to charge from time to time all or any item of the Common Facilities Charges, Taxes, Landlord’s Insurance, or any other
Additional Rent on the basis of either the Building or the Project subject to the terms of this Lease. For all items to be charged for the Building, the Tenant’s Pro Rata Share of the Building shall be used and, for all items relating to the
Project, Tenant’s Pro Rata Share of the Project shall be used for the purposes of calculating such items, as determined by Landlord. 
 4.7 Monthly Deposits. Tenant shall pay, as Additional Rent, to Landlord, as a monthly deposit (“Monthly Deposit”), in advance, without notice, on the day that payment
of Basic Rent is due, an amount equal to 1/12 of Landlord’s estimate of Tenant’s Pro Rata Share of Taxes, Property Insurance (defined in Section 6.1) and Liability Insurance (defined in Section 6.2) (such Property
Insurance and Liability Insurance are collectively referred to herein as “Landlord’s Insurance”), and Common Facilities Charges. 
 4.8 Security Deposit. On or before the Commencement Date, Tenant shall deposit with Landlord, and will keep on deposit at all times during the Lease Term, the amount set forth in
Section 8 of the Summary, as security for the payment by Tenant of all rent and other amounts agreed to be paid and for the performance of all the terms and conditions of this Lease to be performed by Tenant (the “Security
Deposit”). If Tenant shall be in default in the performance of any provision of this Lease, Landlord shall have the right to use the Security Deposit, or so much as is necessary, in payment of any rent or other amounts in default,
reimbursement of expenses incurred by Landlord, and payment of damages incurred by Landlord by reason of Tenant’s default. In such event, Tenant shall, on written demand of Landlord, promptly remit to Landlord a sufficient amount in cash to
restore the Security Deposit to its original amount. If the Security Deposit is not utilized, it (or as much thereof as has not been utilized for such purposes) 

  
 5 

 
shall be refunded to Tenant, or to whoever is then the holder of Tenant’s interest in this Lease, without interest, upon full performance of this Lease by Tenant. Landlord shall have the
right to commingle the Security Deposit with other funds of Landlord and need not keep it in a trust account. Landlord may deliver the Security Deposit to the purchaser of Landlord’s interest in the Premises in the event such interest is sold,
and Landlord shall then be discharged from further liability with respect to it. If claims of Landlord exceed the deposit, Tenant shall remain liable for the balance of such claims. 

4.9 General Provisions as to Monthly Deposits and Security Deposit. Landlord may commingle the Security Deposit or Monthly
Deposits with Landlord’s own funds and use such funds as Landlord determines. In no event shall Landlord be required to hold such funds in escrow or trust for Tenant. Landlord shall not be obligated to pay interest to Tenant on account of the
Monthly Deposits and Security Deposit. In the event of a transfer by Landlord of Landlord’s interest in the Demised Premises, Landlord or the property manager of Landlord may deliver the remaining balance of any Monthly Deposits and Security
Deposit to the transferee of Landlord’s interest, advise Tenant of the name and address of such transferee and Landlord and such property manager shall thereupon be discharged from any further liability to Tenant with respect to such Monthly
Deposits and Security Deposit provided such transferee has agreed to assume the Landlord’s obligations under this Lease. In the event of a Transfer (as defined in Section 8.16) by Tenant of Tenant’s interest in this Lease,
Landlord shall be entitled to return the Monthly Deposits and Security Deposit to Tenant’s successor in interest and Landlord shall thereupon be discharged from any further liability with respect to the Monthly Deposits and Security Deposit.

 4.10 Annual Adjustment. On or before May 1 following the end of each calendar year of the Lease Term (or
as soon thereafter as is reasonably practical), Landlord shall submit to Tenant a statement setting forth the exact amount of Tenant’s Pro Rata Share of Taxes, Landlord’s Insurance, and Common Facilities Charges for the previous calendar
year (the “Statement”). The Statement shall also set forth the estimated the Monthly Deposits for the current calendar year. If Landlord determines that the actual amount of Tenant’s Pro Rata Share of Taxes,
Landlord’s Insurance, and Common Facilities Charges for the previous calendar year exceeds the Monthly Deposits for such previous calendar year, Tenant shall pay to Landlord, within thirty (30) days after receipt of the Statement, such
deficiency in the amount reflected in the Statement. If Landlord determines that the Monthly Deposits exceeded the actual amount of Tenant’s Pro Rata Share of Taxes, Landlord’s Insurance and Common Facilities Charges for the previous
calendar year, the excess amount shall, at Landlord’s option, and except as may be otherwise provided by law, either be paid to Tenant or credited against future Monthly Deposits or against Basic Rent, Additional Rent or other amounts next
payable by Tenant under this Lease. If Tenant disputes any Statement submitted by Landlord, including the estimated Monthly Deposits, Tenant shall give Landlord notice of such dispute within sixty (60) days after Landlord provides the Statement
to Tenant. If Tenant does not give Landlord timely notice, Tenant waives its right to dispute that particular Statement and Tenant shall be deemed to have accepted the calculation of the Taxes, Landlord’s Insurance and Common Facilities Charges
and Tenant’s Pro Rata Share thereof for such calendar year, and neither Landlord nor Tenant shall thereafter be entitled to dispute or object to that particular Statement or the calculation thereof. If Tenant timely objects and provided that
Tenant has paid the entire amount of Tenant’s Pro Rata Share of Taxes, Landlord’s Insurance and Common Facilities Charges and is not in default 

  
 6 

 
of its obligations under this Lease, then Tenant for a period of sixty (60) days after Tenant’s notice may, on a non-contingency fee basis, engage its own certified public
accountant (“Tenant’s Accountant”) to verify the accuracy of the Statement objected to by Tenant. During such 60-day period, Tenant’s Accountant shall be entitled to examine the books and records of Landlord
pertaining to that particular Statement, which examination shall be conducted only during the regular business hours of Landlord at the office where Landlord maintains such books and records. Tenant’s Accountant shall enter into a commercially
reasonable confidentiality agreement with Landlord. Tenant shall deliver to Landlord copies of all audits, reports or other results from its examination within fifteen (15) days after receipt thereof by Tenant. All costs incurred by Tenant for
Tenant’s Accountant shall be paid by Tenant. Notwithstanding any pending dispute, Tenant shall continue to pay Landlord the amount of the estimated Monthly Deposits until such amount has been determined to be incorrect. The amounts of Taxes,
Landlord’s Insurance and Common Facilities Charges payable by Tenant for the calendar years in which the Lease Term commences and expires shall be subject to the provisions hereinafter contained in this Lease for proration of such amounts in
such years. Prior to the dates on which payment is due for Taxes, Landlord’s Insurance and Common Facilities Charges, Landlord shall make payment of Taxes, Landlord’s Insurance and Common Facilities Charges, to the extent of funds from
Monthly Deposits are available therefor and, upon request by Tenant, shall furnish Tenant with a copy of any receipt for such payments. Except for Landlord’s obligation to make payments out of funds available from Monthly Deposits, the making
of Monthly Deposits by Tenant shall not limit or alter Tenant’s obligation to pay Taxes and to maintain insurance as elsewhere provided in this Lease. The obligations of the parties under this Section shall survive the termination or expiration
of this Lease or the early termination of Tenant’s right to occupy the Demised Premises. All costs incurred by Tenant for Tenant’s Accountants shall be paid by Tenant, unless as a result of Tenant’s audit it is determined that the
amount charged Tenant as Tenant’s Pro Rata Share of Taxes, Landlord’s Insurance and Common Facilities Charges exceeded the actual amount thereof by five percent (5%) or more, in which event Landlord shall reimburse Tenant for the
reasonable cost of Tenant’s audit within thirty (30) days after receipt thereof (which costs (i) must be determined on a reasonable hourly basis, and not a percentage or contingent fee basis and (ii) shall not exceed
[...***...]). 
 4.11 Partial Occupancy. For purposes of determining Tenant’s Pro Rata Share of the
Common Facilities Charges that vary based on occupancy and any other costs that vary by occupancy (collectively, “Variable Expenses”), if the Building or the Project is not fully occupied during all or a portion of any
calendar year, Landlord may make appropriate adjustments to Variable Expenses for such calendar year to determine the amount of Variable Expenses that would have been paid or incurred by Landlord had the Building or the Project been 95% occupied,
and the amount so determined shall be deemed to have been the amount of Variable Operating Expenses for such calendar year. 
  

	V.	TAXES. 

 5.1
Covenant to Pay Taxes. Tenant covenants and agrees to pay, as Additional Rent, Tenant’s Pro Rata Share of Taxes, as hereinafter defined, which accrue during or are attributable to the Lease Term, as it may be extended from time to
time. “Taxes” shall mean all taxes, assessments or other impositions, general or special, ordinary or extraordinary, of every kind or nature, which may be levied, assessed or imposed upon or with respect to the Property or

  

					
		  	7	  	* Confidential Treatment Requested

 
the Project (as the case may be), or any part thereof, or upon any building, improvements or personal property at any time situated thereon. Any expenses incurred by Landlord in obtaining or
attempting to obtain or negotiating a reduction of any Taxes (including any interest due on such Taxes or on monies used to pay such Taxes) shall be added to and included in the amount of any such Taxes; provided, however, that any
reduction in Taxes or refund received by Landlord for any year in which Tenant was required to, and did, pay Tenant’s Pro Rata Share of Taxes shall reduce Taxes for such year. 

5.2 Proration at Commencement and Expiration of Term. Taxes shall be prorated between Landlord and Tenant for the year in
which the Lease Term commences and for the year in which the Lease Term expires as of, respectively, the commencement date of the Lease Term and the date of expiration of the Lease Term, except as hereinafter provided. Additionally, for the year in
which the Lease Term expires, Tenant shall be liable without proration for the full amount of Taxes relating to any improvements, fixtures, equipment or personal property which Tenant is required to remove or in fact removes as of the expiration of
the Lease Term. Proration of Taxes shall be made on the basis of actual Taxes. Tenant’s Pro Rata Share of Taxes for the years in which the Lease Term commences and expires shall be paid and deposited with the Landlord through Monthly Deposits
as hereinabove provided. 
 5.3 Special Assessments. If any Taxes are payable in installments over a period of
years, Tenant shall be responsible only for installments for periods during the Lease Term with proration, as above provided, of any installment payable prior to the commencement date or after the expiration date of the Lease Term. 

5.4 New or Additional Taxes. Tenant’s obligation to pay Tenant’s Pro Rata Share of Taxes shall include any Taxes
of a nature not presently in effect but which may hereafter be levied, assessed or imposed upon Landlord or upon the Property or the Project (as the case may be), if such tax shall be based upon or arise out of the ownership, use or operation of or
the rents received therefrom, other than income taxes, transfer taxes or estate taxes of Landlord. For the purposes of computing Tenant’s liability for such new type of tax or assessment, the Property shall be deemed the only property of
Landlord. 
 5.5 Landlord’s Sole Right to Contest Taxes. Landlord shall have the sole right to contest any
Taxes. Landlord shall credit Tenant with Tenant’s Pro Rata Share of any abatement, reduction or recovery of any Taxes attributable to the Lease Term less Tenant’s Pro Rata Share of all reasonable costs and expenses incurred by Landlord,
including attorney’s fees, in connection with such abatement, reduction or recovery. 
  

	VI.	INSURANCE. 

 6.1
Property Insurance. Landlord covenants and agrees to maintain property insurance (“Property Insurance”) for the Building, the shell and core of the Building and the Demised Premises in such amounts, from such
company, with such deductible and on such terms and conditions as Landlord deems appropriate, in its sole and subjective discretion, from time to time including, without limitation, extended coverage and insurance for loss of rent, boilers, exterior
plate glass and other exterior glass. Property Insurance obtained by Landlord need not name Tenant as an additional insured party and may, at Landlord’s option, name any Mortgagee 

  
 8 

 
(as hereinafter defined) as an additional insured party as its interests may appear. Tenant covenants and agrees to pay, as Additional Rent, its Pro Rata Share of the cost of the Property
Insurance obtained by Landlord for the Property or the Project (as the case may be) and the cost of any deductible under such Property Insurance. 
 6.2 Tenant’s Insurance. Tenant covenants and agrees to maintain throughout the Lease Term insurance coverage at least as broad as ISO Causes of Loss—Special Form Coverage against
risk of direct physical loss or damage (commonly known as “all risk”) for the full replacement cost of Tenant’s equipment, fixtures, improvements, Changes (as hereinafter defined) and personal property in the Demised Premises
(collectively “Physical Damage Insurance”). Tenant covenants and agrees to maintain throughout the Lease Term a commercial general liability policy, including protection against death, personal injury and property damage,
issued by an insurance company qualified to do business in the state in which the Demised Premises are located and with a single limit of not less than [...***...] per occurrence. Such policy shall name Landlord, its property manager and the
Mortgagee as additional insureds, be primary to any other similar insurance as such additional insureds, and provide that it may not be cancelled or modified without at least thirty (30) days prior notice to Landlord and Mortgagee. The minimum
limits of such insurance do not limit the liability of Tenant hereunder. Prior to occupancy of the Demised Premises and prior to expiration or the then-current policy, Tenant shall deliver to Landlord certificates evidencing that insurance required
under this Lease is in effect. Tenant covenants and agrees to obtain all other insurance, coverages, and endorsements customarily maintained by companies in the general business and use or reasonably requested by Landlord from time to time,
including, without limitation, business interruption insurance and workers compensation insurance. The commercial general liability policy obtained by Tenant shall not contain any retention or self-insurance provision, except for Tenant’s
customary deductible (not to exceed [...***...]). 
 6.3 Liability Insurance. Landlord covenants and agrees
to maintain a commercial general liability policy (“Liability Insurance”) covering the Common Facilities of the Property or the Project (as the case may be) in such amounts, from such company, with such deductible and on such
terms and conditions as Landlord deems appropriate, in its reasonable discretion consistent with market standards, for the entire Lease Term and extensions thereof. Liability Insurance obtained by Landlord need not name Tenant as an additional
insured party and may, at Landlord’s option, name the Mortgagee as an additional insured party. Tenant covenants and agrees to pay, as Additional Rent, its Pro Rata Share of the cost of the Liability Insurance obtained by Landlord and the cost
of any deductible under the Liability Insurance. 
 6.4 Waiver of Recovery. Landlord and Tenant each waive all
right of recovery against the other and its respective officers, partners, members, agents, representatives and employees for loss or damage to its real and personal property kept in or about the Building or the Project which is capable of being

efforts to obtain an appropriate waiver of subrogation in the policies.

structural elements of the Buildings and systems and the Improvements, which shall be at Landlord’s sole cost except as expressly included in Common Facilities Charges. Landlord, at its sole cost and expense, shall be responsible for the

		  	12	  	* Confidential Treatment Requested

 
Section shall be determined in Landlord’s reasonable discretion consistent with comparable building in the area. For the purposes of this Section, all work and costs for the roofs of the
Building and parking lots servicing the complex shall be considered to be maintenance and repairs included in the Common Facilities Charges, except for the replacement of the entire roofing system of the Building by Landlord hereunder. 

7.5 Building Services. 
 (a) Landlord shall cause to be made available at general points of usage in the Demised Premises facilities for the supply of domestic hot (or tempered) and cold running water, and facilities for electric
power for normal lighting and small office equipment. Tenant shall maintain the heating and air conditioning for the Demised Premises at such temperatures as are customary for similar quality office buildings in the area, as reasonably approved by
Landlord, during not less than Normal Business Hours (as herein defined). Normal Business Hours shall mean the hours of 8:00 a.m. to 5:30 p.m., Monday through Friday, and 8:00 a.m. to 1:00 p.m. on Saturdays, except during any governmental or bank
holiday. Notwithstanding the foregoing and subject to the provisions of Section 7.5(b) below, it is acknowledged by Landlord and Tenant that Tenant may operate its computer rooms within the Premises on a 24 hour, 7 day a week basis.

 (b) Tenant shall be entitled to connect high wattage electrical equipment (including, without limitation, computer equipment
and large copy machines) and install heat generating equipment or machinery in the Demised Premises provided that Tenant, at its sole cost, shall be responsible for all alterations or improvements to the HVAC, electric or other utility systems
serving the Demised Premises and subject to Landlord’s prior written consent which shall not be unreasonably withheld, conditioned or delayed. Tenant shall not make any alterations or improvements to the Demised Premises or install any
equipment or machinery which would affect other HVAC systems in the Building. Tenant shall pay, as Additional Rent, the cost of any modifications to the electrical system or heating and air conditioning system of the Building necessitated by such
usage and the cost of any additional electrical service provided to Tenant, unless billed directly to Tenant by the utility company. 
 (c) Except in the event of Landlord’s gross negligence or misconduct, Landlord shall not be liable for any damage, loss or expense incurred by Tenant by reason of any interruption, reduction
(permanent or temporary) or failure of any utilities or services for the Demised Premises or the Building. Landlord may, with prior written notice to Tenant (except that no notice shall be required in the event of an emergency), cut off and
discontinue any utilities and services when such discontinuance is necessary in order to make repairs or alterations or if otherwise required in connection with the fulfillment of Landlord’s obligations under this Lease; provided, however,
Landlord shall use good faith efforts to minimize any interference with Tenant’s business operations. In no event shall Tenant be entitled to any abatement of rent as a result of the Demised Premises being rendered unusable for their intended
purpose due to any such failure, interruption or reduction. No failure, interruption or reduction of utilities or services shall be construed as an eviction or disturbance of possession by Landlord and Tenant shall have no right to terminate this
Lease as a result thereof. Notwithstanding anything in this Section 7 to the contrary, if (i) the Demised Premises, or a material portion of the Demised Premises, is made untenantable for a period in excess of
five (5) consecutive business 

  
 13 

 
days as a result of an interruption of essential services, such as fire protection or water, that is a result of Landlord’s negligence or willful misconduct or is otherwise within
Landlord’s reasonable control and (ii) Tenant is unable to, and does not, conduct its normal business operations in all or any material portion of the Demised Premises as a result thereof, then Tenant shall be entitled to receive an
abatement of Basic Rent and Additional Rent payable hereunder during the period beginning on the sixth (6th) consecutive Business Day of the service failure and ending on the day the service has been restored; provided, however, that (1) the foregoing conditional abatement of Basic Rent and
Additional Rent shall not apply to the extent that the interruption is a result of Tenant’s negligence, willful misconduct or breach of this Lease and (ii) such abatement shall be in proportion to the portion of the Demised Premises which
Tenant is unable to use. In no event, however, shall Landlord be liable to Tenant for any loss or damage, direct or indirect, special or consequential, including loss of business, arising out of or in connection with the failure of any such utility
services. The foregoing provisions regarding interruption of utility services shall not apply in case of damage to or destruction of the Premises, which shall be governed by Section 9 of this Lease. 

(d) Tenant shall promptly notify Landlord of any accidents or defects in the Building or the Project of which Tenant becomes aware,
including defects in pipes, electric wiring and HVAC equipment, and of any condition which may cause injury or damage to the Building or the Project or any person or property therein. 

7.6 Additional Services. If Tenant requests and Landlord agrees to provide any additional services which may be required by
Tenant, including locksmithing, non-Project standard lamp replacement, additional janitorial services and maintenance, Tenant shall pay to Landlord, upon billing, all of Landlord’s costs for such additional services, plus an administrative fee
equal to [...***...] of such additional service. Charges for any service for which Tenant is required to pay hereunder shall be deemed to be Additional Rent and shall be billed monthly.

 8.11 No Violation of Covenants. Tenant covenants and agrees not to commit,
suffer or permit any violation of any covenant, condition or restriction affecting the Demised Premises or the Property. 

8.12 Restriction on Changes and Alterations. Tenant covenants and agrees not to structurally improve, change, alter, add
to, remove or demolish any improvements on the Demised Premises (“Changes”), without the prior written consent of Landlord which consent shall not be unreasonably withheld, conditioned or delayed and unless Tenant complies
with all conditions which may be imposed by Landlord, in its reasonable discretion, in connection with such consent; and unless Tenant pays, as Additional Rent, to Landlord the reasonable costs and expenses of Landlord for architectural, engineering
or other consultants which may be reasonably incurred by Landlord in determining whether to approve any such Changes. Notwithstanding the foregoing, Landlord hereby consents to the Changes to be made as part of Tenant’s Work; provided,
however, that such Changes are performed in accordance with the terms and conditions of the Work Letter attached hereto. Landlord’s consent to any Changes and the conditions imposed in connection therewith shall be subject to all
reasonable requirements and restrictions of any Mortgagee. If such consent is given, no such Changes shall be permitted unless (a) Tenant shall have procured and paid for all necessary permits and authorizations from any governmental
authorities having jurisdiction; (b) such Changes are located wholly within the Demised Premises, shall not adversely affect the structural integrity of the Building or the operation of the HVAC, plumbing, electrical, water, or sewer systems
servicing the Building or the Property; (c) such Changes shall not affect or impair existing insurance on the Property; and (d) Tenant, at Tenant’s sole cost and expense, shall maintain or cause to be maintained workmen’s

Landlord may reasonably require. Tenant covenants and agrees that any Changes approved by Landlord shall be completed with due diligence and in a good and workmanlike fashion and in compliance with all reasonable conditions imposed by Landlord and
all applicable permits, authorizations, laws, ordinances, orders, rules and regulations of governmental authorities having jurisdiction and that the costs and expenses with respect to such Change shall be paid promptly when due and that the Change

Demised Premises by, through or under Tenant. At least twenty (20) days prior to any Changes, Tenant shall provide written notice to Landlord of the date of commencement of any Changes. Landlord shall have the right, at any time and from time
to time, to post and maintain on the Demised Premises and Building 

  
 16 

 
such notices as Landlord deems necessary to protect the Demised Premises against such liens. Tenant shall have the right to contest, in good faith and with reasonable diligence, the validity of
any such lien or claimed lien, provided that Tenant shall give to Landlord such security as may be reasonably requested by Landlord but in no event more than [...***...] of the lien amount, to insure the payment of any amounts claimed,
including interest and costs, and to prevent any sale, foreclosure or forfeiture of any interest in the Property on account of any such lien, including, without limitation, bonding, escrow or endorsement of the title insurance policy of Landlord and
any Mortgagee. If Tenant so contests, then on final determination of the lien or claim for lien, Tenant shall immediately pay any judgment rendered, with interest and costs, and shall cause the lien to be released and any judgment satisfied.

 8.14 No Other Encumbrances. Tenant covenants and agrees not to obtain any financing secured by Tenant’s

Premises free from all liens and encumbrances except liens and encumbrances existing upon the date of commencement of the Lease Term or liens and encumbrances created by Landlord. 

8.15 Subordination to Landlord Mortgages. 
 (a) Tenant covenants and agrees that this Lease and Tenant’s interest in the Demised Premises shall be junior and subordinate to any mortgage or deed of trust (“Mortgage”) now
or hereafter encumbering the Property. In the event of a foreclosure of any Mortgage, Tenant shall attorn to the party acquiring title to the Property as the result of such foreclosure. No act or further agreement by Tenant shall be necessary to
establish the subordination of this Lease to any such Mortgage, which subordination is self-executing, but Tenant covenants and agrees, upon request of Landlord, to execute such documents as may be necessary or appropriate to confirm and establish
this Lease as subordinate to any Mortgage in accordance with the foregoing provisions. Alternatively, Tenant covenants and agrees that, at the option of any mortgagee or holder of a Mortgage encumbering the Property
(“Mortgagee”). Tenant shall execute commercially reasonable documents as may be necessary to establish this Lease and Tenant’s interest in the Demised Premises as superior to any such Mortgage within thirty (30)
days after Tenant’s receipt thereof. If Tenant fails to execute any commercially reasonable documents required to be executed by Tenant under the provisions hereof, Tenant shall be deemed to have agreed to and be bound by the covenants, terms
and conditions provided in such documents. If any Mortgagee or purchaser at foreclosure thereof, succeeds to the interest of Landlord in the Land or the Building, such person shall not be (i) liable for any act or omission of Landlord under
this Lease; (ii) liable for the performance of Landlord’s covenants hereunder which arise prior to such person succeeding to the interest of Landlord hereunder (provided, however, such successor Landlord shall not be relieved of
Landlord’s obligations that arise from and after such successor assumes this Lease); (iii) bound by the payment of any rent which Tenant may have paid more than one month in advance; (iv) liable for any security deposit which was not
delivered to such person; or (v) bound by any modifications to this Lease to which such Mortgagee has not consented in writing, 
 (b) Within a reasonable time after Tenant’s written request, Landlord shall, subject to the terms and conditions of this Section 8.15(b) use reasonable efforts to obtain for

  

					
		  	17	  	* Confidential Treatment Requested

 
Tenant from the existing Mortgagee a subordination, non-disturbance and attornment agreement on such Mortgagee’s standard form (each, a “SNDA”). Notwithstanding the
foregoing, the Lease and Tenant’s obligations thereunder shall not be affected or impaired in any respect should any Mortgagee decline to enter into a SNDA. If such Mortgagee executes and delivers to Landlord a SNDA and Landlord delivers the
same to Tenant, and Tenant either fails or refuses to execute and deliver the SNDA within 20 days following Landlord’s delivery of such SNDA to Tenant, then Landlord shall have no further obligation to obtain a SNDA for Tenant from such
Mortgagee. In no event shall Landlord be required to (i) expend any material sums in its effort to obtain the SNDA, (ii) commence any litigation in order to obtain the SNDA or (iii) take any step which may, in Landlord’s
judgment, have an adverse effect on its relationship with any Mortgagee. If any Mortgagee shall impose any fee as a condition of entering into the SNDA, Landlord may withdraw its request therefor unless, within 10 days after Landlord’s notice
to Tenant as to such fee and the amount thereof, Tenant shall agree, in writing, to pay such fee. 
 8.16 No Assignment or
Subletting. 
 (a) Tenant covenants and agrees not to make or permit a Transfer by Tenant, as hereinafter defined,
without Landlord’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. A “Transfer” by Tenant shall include an assignment of this Lease, a sublease of all or any part of the
Demised Premises or any assignment, sublease, transfer, mortgage, pledge or encumbrance of all or any part of the Demised Premises or of Tenant’s interest under this Lease or in the Demised Premises, by operation of law or otherwise, or the use
or occupancy of all or any part of the Demised Premises by anyone other than Tenant. Any such Transfer by Tenant without Landlord’s written consent shall be void and shall constitute a Default by Tenant under this Lease. If Landlord consents to
any Transfer by Tenant, Tenant shall not be relieved of its obligations under this Lease and Tenant shall remain liable, jointly and severally, and as a principal, not as a guarantor or surety, under this Lease, to the same extent as though no
Transfer by Tenant had been made, unless specifically provided to the contrary in Landlord’s prior written consent. The acceptance of rent by Landlord from any person other than Tenant shall not be deemed to be a waiver by Landlord of the
provisions of this Section or of any other provision of this Lease and any consent by Landlord to a Transfer by Tenant shall not be deemed a consent to any subsequent Transfer by Tenant. 

(b) If Tenant requests Landlord’s consent to a Transfer, Tenant shall submit to Landlord in writing the name of the proposed
transferee, the effective date of the Transfer, the terms of the proposed Transfer, a copy of the proposed form of sublease or assignment, and such information as to the business, reputation, responsibility, and financial capacity of the transferee
as Landlord shall reasonably require to evaluate the request. It shall be reasonable for the Landlord to withhold its consent to any Transfer where: (i) in the case of a sublease, the subtenant has not acknowledged that the provisions of this
Lease control over any inconsistent provision in the sublease; or (ii) in Landlord’s reasonable opinion, the proposed transferee does not have the ability to perform its obligations under the assignment or sublease; or (iii) the
intended use by the transferee would damage the goodwill or reputation of the Building; or (iv) the intended use is not compatible with other uses of the Building, conflicts with another tenant’s right to exclusive use, or is not permitted
by applicable law or covenant. The foregoing criteria are not exhaustive, and Landlord may withhold consent to a Transfer on any other reasonable 

  

					
		  	18	  	

 
grounds. Tenant shall reimburse Landlord for all of Landlord’s costs incurred in connection with any request for consent to a Transfer, including, without limitation, a reasonable sum for
attorneys’ fees not to exceed [...***...]. 
 (c) If Tenant consummates a Transfer other than a Permitted Transfer
(as defined in Rider 1 attached hereto), Tenant shall pay over to Landlord, as Additional Rent, [...***...] of all sums received by Tenant in excess of the rent payable by Tenant hereunder which is attributable on an equally
allocable Floor Area basis, to any subletting of all or any portion of the Demised Premises so subleased, and [...***...] of all consideration received on account of or attributable to any assignment of this Lease, in each case net of all
expenses and costs incurred by Tenant in connection with such Transfer, including, without limitation, commissions, allowances, improvement costs and other concessions provided to the sublessee or assignee. 

(d) If Landlord consents to a Transfer by Tenant, then any option to renew this Lease, right to extend the Lease Term, or option or right
of refusal to expand the Demised Premises shall automatically terminate. 
 (e) Tenant covenants and agrees to pay, as
Additional Rent to Landlord, the amount of [...***...] as the total fee to compensate Landlord for processing such request whether or not the consent of Landlord is given to the Transfer requested by Tenant. Tenant shall pay such
[...***...] administrative charge, which shall be due and payable to Landlord at the time that Tenant submits such request for consent to the Transfer to Landlord. The payment of such administrative charge and other costs and expenses by
Tenant shall be a condition precedent to the effectiveness of any consent by Landlord to such Transfer. 
 (f) Notwithstanding
anything to the contrary, so long as Landlord has any comparable vacancy in the Project (or any pending vacancy in the Project), Tenant shall not be entitled to make a Transfer to an existing tenant of the Project, or any person or entity with whom
Landlord or its Related Parties (as herein defined) negotiated any written proposal regarding a lease of space in the Project within the six (6) month period preceding Tenant’s request for such Transfer. 

(g) For the purposes of this Lease, the term “Transfer” shall also include: the transfer or change, whether voluntary,
involuntary or by operation of law, of forty-nine percent (49%) or more of the control or ownership, whether legal or beneficial, in Tenant within a twelve (12) month period; the dissolution, merger, consolidation or other reorganization
of Tenant; or the withdrawal, resignation or termination of the majority of any general partners, managers or board of directors of Tenant. Notwithstanding the foregoing, Landlord acknowledges that Tenant is a publicly traded company and that this
Section 8.16(g) shall not apply to Tenant so long as Tenant’s stock is traded on a public exchange or over the counter market. 
 (h) As a condition to Landlord’s consent to a Transfer by Tenant (including a Permitted Transfer), any assignee shall expressly assume all the obligations of Tenant under this Lease in a written
instrument reasonably satisfactory to Landlord and furnished to Landlord not later than fifteen (15) days prior to the effective date of such assignment, and any subtenant shall covenant to Landlord to comply with all obligations of Tenant
under this Lease as applied to the 

  

					
		  	19	  	* Confidential Treatment Requested

Term, all of which shall be in a written instrument satisfactory to Landlord and furnished to Landlord not later than fifteen (15) days prior to the effective date of such sublease. 

(i) Notwithstanding anything to the contrary contained herein, in no event shall Tenant assign this Lease or enter into any Transfer for
the possession, use, occupancy or utilization (collectively, “use”) of any part of the Demised Premises which (i) provides for a rental or other payment for such use based in whole or in part on the income or profits
derived by any person from the Demised Premises (other than an amount based on a fixed percentage or percentages of gross receipts or sales), and Tenant agrees that all assignments and subleases of any part of the Demised Premises shall provide that
the person having an interest in the use of the Demised Premises shall not enter into any lease or sublease which provides for a rental or other payment for such use based in whole or in part on the income or profits derived by any person from the
Demised Premises (other than an amount based on a fixed percentage or percentages of gross receipts of sales), or (ii) would cause any portion of the amounts payable to Landlord hereunder to not constitute “rents from real property”
within the meaning of Section 856(d) of the Internal Revenue Code, and any such purported Transfer shall be absolutely void and ineffective as a conveyance of any right or interest in the possession, use, occupancy or utilization of any
part of the Demised Premises.

8.19 Estoppel Certificates. Tenant covenants and agrees to execute, acknowledge and deliver to Landlord, within
ten (10) business days after Landlord’s written request, a written statement certifying that this Lease is unmodified (or, if modified, stating the modifications) and in full force and effect; stating the dates to which Basic Rent has

request.

Tenant agrees that such statement may be delivered to and relied upon by any existing or prospective Mortgagee or purchaser of the Property. If Tenant fails to deliver such a statement within
such 10-business day period, Landlord may send a second request to Tenant (each, an “Estoppel Reminder Notice”). Tenant agrees that a failure to deliver such a statement within three (3) business days after receipt

 28 

 
costs and expenses of Landlord in connection with the making of any such payment or the taking of any such action including, without limitation, (a) a charge in the amount of
[...***...] of such advances, costs and expenses payable to Landlord to compensate for the administrative overhead attributable to such action, (b) reasonable attorneys’ fees, and (c) interest as hereinafter provided from the

Term has expired or Tenant is no longer occupying the Demised Premises, Landlord shall be entitled to take such actions as provided under this Section 12.2 without Landlord being required to provide the notice to Tenant under
Section 11.3. 
 12.3 Termination of Lease and Damages. In the event of a Default by Tenant, Landlord
may terminate this Lease, effective at such time as may be specified by written notice to Tenant, and demand (and, if such demand is refused, recover) possession of the Demised Premises from Tenant. Tenant shall remain liable to Landlord for damages
in an amount equal to the Basic Rent, Additional Rent and other sums which would have been owing by Tenant hereunder for the balance of the Lease Term, had this Lease not been terminated, less the net proceeds, if any, of any reletting of the
Demised Premises by Landlord subsequent to such termination, after deducting all Landlord’s expenses in connection with such recovery of possession or reletting. Landlord shall be entitled to collect and receive such damages from Tenant on the
days on which the Basic Rent, Additional Rent and other amounts would have been payable if this Lease had not been terminated. Alternatively, at the option of Landlord, Landlord shall be entitled to recover forthwith from Tenant, as damages for loss
of the bargain and not as a penalty, an aggregate sum which, at the time of such termination of this Lease, represents the excess, if any, of (a) the aggregate of the Basic Rent, Additional Rent and all other sums payable by Tenant hereunder
that would have accrued for the balance of the Lease Term, over (b) the aggregate rental value of the Demised Premises for the balance of the Lease Term, both discounted to present worth at the rate of 8% per annum.

Demised Premises or any part thereof, without demand or notice, and repossess the same and expel Tenant and any party claiming by, under or through Tenant, and remove the effects of both using such force for such purposes as may be necessary,
without being liable for prosecution on account thereof or being deemed guilty of any manner of trespass, and without prejudice to any remedies for arrears of rent or right to bring any proceeding for breach of covenants or conditions. No such
reentry or taking possession of the Demised Premises by Landlord shall be construed as an election by Landlord to terminate this Lease unless a written notice of such intention is given to Tenant. No notice from Landlord hereunder or under a
forcible entry and detainer statute or similar law shall constitute an election by Landlord to terminate this Lease unless such notice specifically so states. Landlord reserves the right, following any reentry or reletting, to exercise its right to
terminate this Lease by giving Tenant such written notice, in which event this Lease shall terminate as specified in said notice. Subject to applicable law, after recovering possession of the Demised Premises, Landlord shall use reasonable efforts
to re-let the Demised Premises, or any part thereof, for the account of 

  

					
		  	29	  	* Confidential Treatment Requested

 
Tenant, for such term or terms and on such conditions and upon such other terms as Landlord, in its reasonable discretion, may determine. Landlord may make such repairs, alterations or
improvements as Landlord may consider reasonably appropriate to accomplish such reletting, and Tenant shall reimburse Landlord upon demand for all reasonable costs and expenses, including reasonable attorneys’ fees, which Landlord may incur in
connection with such reletting. Landlord may collect and receive the rents for such reletting but Landlord shall in no way be responsible for or liable for any failure to relet the Demised Premises, or any part thereof, or for any failure to collect
any rent due upon such reletting. Notwithstanding Landlord’s recovery of possession of the Demised Premises, Tenant shall continue to pay on the dates herein specified, the Basic Rent, Additional Rent and other amounts which would be payable
hereunder if such repossession had not occurred. Landlord shall promptly refund to Tenant any amount, without interest, by which the amounts paid by Tenant, when added to the net amount, if any, recovered by Landlord through any reletting of the
Demised Premises, exceeds the amounts payable by Tenant under this Lease. If, in connection with any reletting, the new lease term extends beyond the existing Lease Term, or the premises covered thereby include other premises not part of the Demised
Premises, a fair apportionment of the rent received from such reletting and the expenses incurred in connection therewith shall be made in determining the net amount recovered from such reletting. 

12.5 Landlord’s Lien and Enforcement. [Intentionally deleted]. 

12.6 Suits by Landlord. Actions or suits for the recovery of amounts and damages payable under this Lease may be brought by
Landlord from time to time, at Landlord’s election, and Landlord shall not be required to await the date upon which the Lease Term would have expired to bring any such action or suit. 

12.7 Recovery of Landlord Enforcement Costs. All costs and expenses incurred by the prevailing party in connection with an
action for collecting any amounts and damages owing by Tenant pursuant to the provisions of this Lease or to enforce any provision of this Lease, including reasonable attorneys’ fees, whether or not any action is commenced by either party,
shall be paid by the non-prevailing party to the other upon demand. 
 12.8 Administrative Late
Charge. Notwithstanding any other remedies for nonpayment of rent, if the monthly payment of Basic Rent and Additional Rent are not received by Landlord on or before the fifth (5th) day of the month for which such rental is due, or if any other payment due Landlord by Tenant is not received by
Landlord on or before the fifth (5th) business day of
the month next following the month in which Tenant was invoiced, an administrative late charge of [...***...] of such past due amount shall become due and payable, as Additional Rent, in addition to such amounts owed under this Lease to help
defray the additional cost to Landlord for processing such late payments. 
 12.9 Interest on Past-Due Payments and
Advances. Tenant covenants and agrees to pay Landlord, as Additional Rent, interest on demand at the rate of [...***...] per annum, compounded on a monthly basis, on the amount of any Basic Rent, Additional Rent or other charges not

be greater, equal or less than the amounts recoverable, either as damages or rent, under this Lease.

bears any costs of such transfer. 
 13.2 Holding Over. If Tenant shall hold over after the expiration of the
Lease Term, without written agreement providing otherwise, Tenant shall be deemed to be a trespasser upon the Demised Premises. If Landlord consents in writing to such holdover, then Tenant shall be deemed to be a tenant from month to month, at a
monthly rental, payable in advance, equal to [...***...], and Tenant shall be bound by all of the other terms, covenants and agreements of this Lease. Nothing contained herein shall be construed to give Tenant the right to hold over at any
time, and Landlord, if Tenant’s holdover period extends beyond one (1) month, may exercise any and all remedies at law or in equity to recover possession of the Demised Premises, as well as any damages incurred by Landlord, due to

 14.17 Agency Disclosure. 

(a) Landlord is represented by Newmark Knight Frank Frederick Ross, which is acting as Landlord’s agent (“Landlord’s
Broker”). Landlord’s Broker is an agent for Landlord and not an agent for Tenant, unless Landlord’s Broker enters into a written agreement with Tenant to act as its agent. Landlord’s Broker owes duties to Landlord which
include utmost good faith, loyalty and fidelity. Landlord’s Broker will negotiate on behalf of and act as an advocate for Landlord. Please do not tell Landlord’s Broker any information which you do not want to share with Landlord. Landlord
is not vicariously liable for the acts of Landlord’s Broker that are not approved, directed or ratified by Landlord. Although Landlord’s Broker does not represent Tenant, Landlord’s Broker shall disclose to Tenant all adverse material
facts about the Demised Premises actually known by Landlord’s Broker. Landlord’s Broker shall assist Tenant without regard to race, creed, sex, religion, national origin, familial status, marital status, or handicap. 

(b) DIFFERENT BROKERAGE RELATIONSHIPS ARE AVAILABLE WHICH INCLUDE SELLER (LANDLORD) AGENCY, BUYER (TENANT) AGENCY, OR
TRANSACTION-BROKER. 
 (c) The definitions of real estate brokerage relationships are provided as follows: A
landlord’s agent: (i) is engaged as a limited agent and works solely on behalf of the landlord; (ii) owes duties to the landlord which include the utmost good faith, loyalty and fidelity; (iii) will negotiate on behalf of and act
as an advocate for the landlord; and (iv) must disclose to potential tenants only adverse material facts about the property actually known by the agent. A broker acting as a landlord’s agent may cooperate with other brokers but may not
engage or create any subagents. A landlord is not vicariously liable for the acts of landlord’s agent that are not approved, directed or ratified by landlord. A separate written listing agreement is required which sets forth the duties and
obligations of the parties, and notice of such agency relationship must be furnished to any prospective party to the proposed transaction in a timely manner. A tenant’s agent: (i) is engaged as a limited agent and works solely on behalf of
the tenant; (ii) owes duties to the tenant which include the utmost good faith, loyalty and fidelity; (iii) will negotiate on behalf of and act as an advocate for the tenant; and (iv) must disclose to potential landlords only adverse
material facts concerning the tenant’s financial ability to perform the terms of the transaction actually known by the agent. A tenant is not vicariously liable for the acts of tenant’s agent that are not approved, directed or ratified by
tenant. A broker acting as a tenant’s agent owes no duty to conduct an independent inspection of the property for the benefit of the tenant, and owes no duty to independently verify the accuracy or completeness of statements made by the
landlord or independent inspectors; provided, however, this does not limit the agent’s duties, as set forth above. A broker acting as a tenant’s agent may cooperate with other brokers but may not engage or create any subagents. A separate
written tenant agency agreement is required which sets forth the duties and obligations of the parties, and notice of such agency relationship must be furnished to any prospective party to the proposed transaction in a timely manner. A broker shall
not establish dual agency with any landlord or tenant. A transaction-broker: (i) will assist a landlord or a tenant or both throughout a real estate transaction with communication, advice, negotiation, contracting and closing without being an
agent or advocate for any of the parties; (ii) does owe the parties a number of statutory obligations and responsibilities, including using reasonable skill and care in the performance of any

  
 34 

 
oral or written agreement; and (iii) must also make the same disclosures as agents about adverse material facts concerning a property or a tenant’s financial ability to perform the
terms of a transaction, but only to the extent actually known by the agent. A transaction broker may cooperate with other brokers but shall not engage or create any subagents. A landlord and tenant shall not be vicariously liable for a
transaction-broker’s acts. A broker shall be considered a transaction-broker unless a single agency relationship is established through a written agreement between the broker and the party(ies) to be represented by such broker.

 14.18 Parking. Provided no Default by Tenant or sublease exists, Tenant shall be entitled to the
non-exclusive use of the Parking Area up to the maximum number of spaces set forth in the Summary, on a first come-first serve basis. Landlord shall be entitled to establish reasonable rules and regulations governing the use of the Parking Area
including, without limitation, the right to issue parking permits and decals to be affixed to motor vehicles (with the reasonable costs thereof being a part of the Common Facilities Charges). Landlord may designate a specific area for Tenant’s
parking spaces within the Parking Area subject to Tenant’s approval. Landlord shall not be liable for and Tenant hereby releases and covenants not to bring any action against Landlord for any loss, damage or theft to or from any motor vehicle
or other property of Tenant or Tenant’s Agents which occurs in or about the Parking Area except as caused by landlord or Landlord’s Agents. If any visitor parking is provided by Landlord in the Parking Area, the use thereof shall be
limited to visitors of Tenant and other tenants of the Project, except as otherwise permitted by Landlord. Notwithstanding the foregoing, Tenant’s right to use such parking spaces shall be a license only and Landlord’s inability to make
such spaces available at any time for reasons beyond Landlord’s control shall not constitute a default by Landlord under this Lease. 
 14.19 Relationship of Landlord and Tenant. Nothing contained herein shall be deemed or construed as creating the relationship of principal and agent or of partnership, or of joint venture by
the parties hereto, it being understood and agreed that no provision contained in this Lease nor any acts of the parties hereto shall be deemed to create any relationship other than the relationship of Landlord and Tenant. 

14.20 Authority of Tenant. Each individual executing this Lease on behalf of Tenant represents and warrants that he or she
is duly authorized to deliver this Lease on behalf of Tenant and that this Lease is binding upon Tenant in accordance with its terms. 
 14.21 Removal of Cabling. Tenant shall be solely responsible for the cost of installation and maintenance of any high speed cable or fiber optic that Tenant requires in the Demised Premises.
Landlord shall provide reasonable access to the Building’s electrical lines, feeders, risers, wiring and other machinery to enable Tenant to install high speed cable or fiber optic to serve its intended purpose, if any. All such cabling
installed shall be tagged by Tenant at their point of entry into the Building, at the terminal end of the cable and in the riser closet indicating the type of cable, the Tenant’s name and the service provided. Tenant shall be responsible for
the removal of such cabling and fiber optic at the termination or expiration of the Lease Term or the early termination of the Tenant’s right to occupy the Demised Premises. Failure to remove any abandoned or unused cabling at the expiration or
termination of the Lease Term or the early termination of Tenant’s right to occupy the Demised Premises will be deemed 

  
 35 

 
to be a holdover under Section 13.2 of the Lease. In the event Tenant fails to remove such cabling as set forth herein, Landlord may, but shall not be obligated to, remove such cabling,
all at Tenant’s sole cost and expense. Notwithstanding anything in this Section 14.21 to the contrary, and provided that Tenant has vacated and surrendered exclusive possession of the Demised Premises on or before the expiration of
this Lease, then (a) Tenant may remain in the Demised Premises for up to five (5) days after the expiration (but not the early termination) of this Lease for the sole purpose of removing the cabling and other items that Tenant is
required to remove pursuant to this Section 14.21. and (b) Tenant’s possession of the Demised Premises for such purpose shall be subject to all of the terms and conditions of this Lease, except that Tenant shall have no
obligation to pay Basic Rent or Tenant’s Pro Rata Share of the Common Facilities Charges, Taxes, or Landlord’s Insurance during such 5-day period. 
 14.22 Force Majeure. Whenever a period of time is herein prescribed for the taking of any action by Landlord or Tenant, Landlord or Tenant shall not be liable or responsible for, and there
shall be excluded from the computation of such period of time, any delays due to strikes, riots, acts of God, shortages of labor or materials, war, governmental laws, regulations or restrictions, or any other cause whatsoever beyond the control of
Landlord.

Agents and (z) a certificate from the Architect, in form and substance satisfactory to each Mortgagee, certifying that, as of the date of the certificate, Tenant’s Work has been completed in accordance with the Approved Working Drawings
(as defined below). Landlord’s payment of such amounts shall not be deemed Landlord’s approval or acceptance of the work furnished or materials supplied as set forth in Tenant’s payment request. 

(ii) Limitations. Landlord’s disbursement of the Tenant Improvement Allowance is subject to the limitations set

 SECTION 3 

CONSTRUCTION DRAWINGS 

3.1 Selection of Architect/Construction Drawings. Tenant shall retain the architect/space planner designated by Tenant (the
“Architect”) to prepare the Construction Drawings; provided, however, the Architect shall be reasonably satisfactory to Landlord and shall be licensed by the State of Colorado. Tenant shall retain the engineering
consultants designated by Tenant (the “Engineers”) to prepare all plans and engineering working drawings relating to the structural, mechanical, electrical, plumbing, HVAC, life safety, and sprinkler work in the Demised
Premises, which work is not part of the Base Building; provided, however, the Engineers shall be reasonably satisfactory to Landlord and shall be licensed by the State of Colorado; provided, further, however, that Landlord may
retain, as an Tenant Improvement Allowance Item, its own engineer to review the Construction Drawings and consult with the Engineers regarding the same. Tenant may retain a project manager to oversee Tenant’s Work (the “Project

reasonable approval. Landlord shall advise Tenant, in writing, within five (5) business days after Landlord’s receipt of the Construction Drawings if the same is unsatisfactory or incomplete in any respect (and specify in such written
notice the unsatisfactory items). If Landlord fails to respond within the time period specified in this Section 3.1, Tenant may send a second notice (each, a “Reminder Notice”) to Landlord requesting
Landlord’s approval. Landlord’s failure to respond within five (5) business days after its receipt of a Reminder Notice shall be deemed as Landlord’s approval. Tenant and Architect shall verify, in the field, the dimensions
and conditions as shown on the relevant portions of the base building plans, and Tenant and Architect shall be solely responsible for the same, and Landlord shall have no responsibility in connection therewith. Landlord’s review of the
Construction Drawings shall be for its sole purpose and shall not imply Landlord’s review of the same, or obligate Landlord to review the same for quality, design, compliance with Laws or other like matters. Accordingly, notwithstanding that
any Construction Drawings are reviewed by Landlord or its space planner, architect, engineers and consultants, and notwithstanding any advice or assistance which may be rendered to Tenant by Landlord or Landlord’s space planner, architect,
engineers, and consultants, Landlord shall have no liability whatsoever in connection therewith and shall not be responsible for any omissions or errors contained in the Construction Drawings, and Tenant’s waiver and indemnity set forth in the
Lease shall specifically apply to the Construction Drawings.

Architect shall compile a fully-coordinated set of architectural, structural (if required), mechanical, electrical and plumbing working drawings in a form which is complete to allow subcontractors to bid on the work and to obtain all applicable
permits (collectively, the “Final Working Drawings”) and shall submit the same to Landlord for Landlord’s approval, which approval shall not be unreasonably withheld, conditioned or delayed. Tenant shall supply Landlord
with two (2) copies signed by Tenant of such Final Working Drawings. Landlord shall advise Tenant, in writing, within five (5) business days after Landlord’s receipt of the Final Working Drawings for Tenant’s Work if
the same is unsatisfactory or incomplete in any respect (and specify in such written notice the unsatisfactory items). If Tenant is so advised, Tenant shall immediately revise the Final Working Drawings in accordance with such review and any
disapproval of Landlord in connection therewith. If Landlord fails to respond within the time period specified in this Section 3.2. Tenant may send a Reminder Notice to Landlord requesting Landlord’s approval. Landlord’s
failure to respond within five (5) business days after its receipt of a Reminder Notice shall be deemed as Landlord’s approval. 

3.3 Approved Working Drawings. The Final Working Drawings with the changes required by Landlord pursuant to Section 3.2 above,
if any, shall be approved by Landlord within five (5) business days after the date Tenant delivers the revised Final Working Drawings to Landlord prior to the commencement of construction of Tenant’s Work (the “Approved
Working Drawings”). If Landlord fails to respond within the time period specified in this Section 3.3, Tenant may send a Reminder Notice to Landlord requesting Landlord’s approval. Landlord’s failure to respond
within five (5) business days after its receipt of a Reminder Notice shall be deemed as Landlord’s approval. Upon receipt by Tenant of the Approved Working Drawings, Tenant may submit the same to the appropriate municipal authorities
for all applicable building permits. Tenant hereby agrees that neither Landlord nor Landlord’s consultants shall be responsible for obtaining any building permit or certificate of occupancy for the Demised Premises and that obtaining the same
shall be Tenant’s sole responsibility; provided, however. that Landlord shall cooperate, at no cost to Landlord, with Tenant in executing permit applications and performing other ministerial acts necessary to enable Tenant to obtain any
such permit or certificate of occupancy. No changes, modifications or alterations in the Approved Working Drawings may be made without the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed.

of the rights, options and concessions set forth in this Rider 1 are personal to the Tenant first named above (together with any assignee that assumes the Lease pursuant to a Permitted Transfer, “Original Tenant”), and may
only be exercised and/or utilized by Original Tenant (and not any assignee, sublessee or other transferee of Original Tenant’s interest in the Tenant). All references to “Tenant” in this Rider 1 shall mean Original Tenant only. Time
is of the essence of this Rider 1. 
  

	2.	TENANT IMPROVEMENT ALLOWANCE; TENANT’S WORK. 

 2.1 The Improvement Allowance. Landlord shall, subject to the terms and conditions of the Lease and the Tenant Work Letter (as defined below), provide Tenant with an improvement allowance
not to exceed [...***...] (the “Tenant Improvement Allowance”), for the purpose of contributing towards the costs of the design, engineering and construction of real property improvements or electrical and HVAC upgrades

	3.	PERMITTED TRANSFER. 

3.1 Permitted Transfer. Notwithstanding anything in Section 8.16 of the Lease to the contrary, and provided

recapitalization of or with Tenant, or to a purchaser of all or substantially all of Tenant’s assets or (b) sublease the Demised Premises or any part thereof to an Affiliate (each, a “Permitted Transfer”):

assignment, an aggregate net worth (computed in accordance with GAAP) at least equal to the aggregate net worth (as so computed) of Tenant immediately prior to such assignment or on the Effective Date, whichever is greater, (iii) no later than
fifteen (15) days prior to the effective date of the Permitted Transfer, Tenant shall give notice to Landlord which notice shall include the full name and address of the assignee or subtenant, and a copy of all agreements executed between
Tenant and the assignee or subtenant with respect to the Demised Premises or part thereof, as may be the case, (iv) no later than fifteen (15) days after the effective date of the Permitted Transfer, the assignee or sublessee shall provide
the documentation required pursuant to Section 8.16(h) of the Lease, and (v) within ten (10) days after Landlord’s written request, provide such reasonable documents or information which Landlord reasonably requests
for the purpose of substantiating whether or not the Permitted Transfer is to an Affiliate or is otherwise in accordance with the terms and conditions of this Rider 1. Tenant shall not have the right to perform a Permitted Transfer, if, as of the

 Rider 1-2

	4.	OPTION TO RENEW. 

4.1 Grant of Option. Subject to the terms and conditions of this Rider 1, Tenant shall have one (1) option
to renew the Lease Term for one (1) consecutive additional period of sixty (60) months (the “Renewal Term”). There shall be no additional renewal terms beyond the Renewal Term set forth herein. Tenant must
exercise its option to extend the Lease Term by giving Landlord written notice (the “Option Exercise Notice”) of its election to do so no later than nine (9) months, and no earlier than fifteen (15) months,
prior to the expiration of the Lease Term. If Tenant fails to timely deliver the Option Exercise Notice in strict accordance with this Rider 1 and the notice provisions of the Lease, then Tenant shall be deemed to have waived its extension rights,
as aforesaid, and Tenant shall have no further right to renew the Lease. 
 4.2 Terms and Conditions of Option.
The Renewal Term shall be on all the terms and conditions of the Lease, except that Landlord shall have no additional obligation for free rent, leasehold improvements or for any other tenant inducements for the Renewal Term, and Basic Rent shall be
adjusted to Market Rent (as defined below). 
 4.3 Market Rent. “Market Rent” means the
annual amount per square foot (exclusive of Operating Expenses) that a willing tenant would pay and a willing landlord would accept in arm’s length bona fide negotiations, for a renewal lease of premises of comparable Class A so-called
“office flex” space (built after 1998) being offered in the southeast suburban Denver submarket as of the end of the Lease Term as determined by Landlord and Tenant as set forth hereafter. The determination of Market Rent shall take into
account typical market concessions, free rent periods, tenant improvement allowances, tenant inducements and costs and adjusted appropriately for any such concessions, allowances and costs not being provided or paid by Landlord in connection with
the renewal of the Lease Term for Tenant’s of comparable size. 
 4.4 “Baseball” Arbitration.
Within thirty (30) days following Landlord’s receipt of Tenant’s Option Exercise Notice, Landlord shall initially deliver to Tenant a designation of Market Rent (“Landlord’s Market Rent Designation”) and
Landlord shall furnish data in support of such designation. Within thirty (30) days after receipt of Landlord’s Market Rent Designation, Tenant shall elect, in writing, either (i) to accept Landlord’s Designation (an
“Acceptance Notice”), (ii) to withdraw the exercise of its option to renew (a “Withdrawal Notice”) or (iii) to submit the determination of market rent to “baseball” arbitration in
accordance with subsections (b) through (f) below (the “Arbitration Notice”). Tenant’s failure to timely deliver either an Acceptance Notice, a Withdrawal Notice or an Arbitration Notice shall be deemed
Tenant’s irrevocable revocation and rescission of its exercise of this option to extend, and, thereafter, Tenant shall have no further right to renew the Lease Term. Upon the timely giving of an Acceptance Notice or an Arbitration Notice, the
Lease Term shall be deemed extended without the need for further act or deed of either party. Following Tenant’s delivery of an Arbitration Notice, Landlord and Tenant shall attempt to agree upon such Market Rent using their good faith efforts.
If Landlord and Tenant fail to reach agreement within fifteen (15) days following Landlord delivery of Landlord’s Market Rent Designation (“Outside Agreement Date”), then each party shall place in a separate sealed
envelope their final proposal as to Market Rent and such determination shall be submitted to “baseball” arbitration in accordance with subsections (b) through (f) below. 

  
 Rider 1-3

 (a) In the event that Landlord fails to timely generate the initial written notice of
Landlord’s Market Rent Designation which triggers the negotiation period of this Section, then Tenant may commence such negotiations by providing the initial Market Rent notice, in which event Landlord shall have fifteen (15) days
(“Landlord’s Review Period”) after receipt of Tenant’s notice of the proposed Market Rent within which to accept such proposal. In the event Landlord fails to accept in writing such Market Rent proposed by Tenant,
then such proposal shall be deemed rejected, and Landlord and Tenant shall attempt in good faith to agree upon Market Rent using good faith efforts. If Landlord and Tenant fail to reach agreement within fifteen (15) days following
Landlord’s Review Period (which shall be, in such event, the “Outside Agreement Date” in lieu of the above definition of such date), then each party shall place in a separate sealed envelope their final proposal as to the Market Rent
along with information justifying their Market Rate determination and such determination shall be submitted to arbitration in accordance with subsections (b) through (f) below. 

(b) Landlord and Tenant shall meet with each other within five (5) business days after the Outside Agreement Date and exchange
the sealed envelopes and then open such envelopes in each other’s presence. If Landlord and Tenant do not mutually agree upon the Market Rent within one (1) business day after the exchange and opening of envelopes, then, within
ten (10) business days after the exchange and opening of envelopes, Landlord and Tenant shall agree upon and jointly appoint a single arbitrator who shall by profession be a real estate broker who shall have been active over the 10-year
period ending on the date of such appointment in the leasing of so-called “flex” space being offered in the Southeast Denver office flex submarket Neither Landlord nor Tenant shall consult with such arbitrator as to his or her opinion as
to Market Rent prior to the appointment. The determination of the arbitrator shall be limited solely to the issue of whether Landlord’s or Tenant’s submitted Market Rent is the closest to the actual Market Rent as determined by the
arbitrator, taking into account the requirements of this Section. Such arbitrator may hold such hearings and require such briefs as the arbitrator, in his or her sole discretion, determines is necessary. In addition, Landlord or Tenant may submit to
the arbitrator, with a copy to the other party, within five (5) business days after the appointment of the arbitrator any market data and additional information that such party deems relevant to the determination of the Market Rent
(“MR Data”) and the other party may submit a reply in writing within five (5) business days after receipt of such MR Data. 
 (c) The arbitrator shall, within thirty (30) days after his or her appointment, reach a decision as to whether the parties shall use Landlord’s or Tenant’s submitted Market Rent, and shall
notify Landlord and Tenant of such determination. 
 (d) The decision of the arbitrator shall be binding upon Landlord and
Tenant. 
 (e) If Landlord and Tenant fail to agree upon and appoint an arbitrator, then the appointment of the arbitrator shall
be made by the Presiding Judge of the Denver County District Court, or, if he or she refuses to act, by any judge having jurisdiction over the parties. 
 (f) The cost of arbitration shall be paid by Landlord and Tenant equally. 
 4.5
Limitations; Termination of Option to Renew. Tenant shall not have the right to renew the Lease for any amount of space less than the entire Premises hereunder. In the event 

  
 Rider 1-4

 
that Tenant assigns the Lease (other than a Permitted Transfer) or subleases, in aggregate, more than 2% of the Demised Premises (other than a Permitted Transfer), the option to renew shall be
extinguished. The renewal option granted herein shall terminate as to the entire Premises upon the failure by Tenant to timely exercise its option to renew at the times and in the manner set forth in this Rider 1. Tenant shall not have the option to
renew, as provided in this Rider 1, if, as of the date of the Option Exercise Notice, or as of the scheduled commencement date of the Renewal Term, (a) Default by Tenant is continuing or (b) Landlord has given more than
two (2) notices of default in any 12-month period for nonpayment of monetary obligations. 
 4.6 Self-Operative;
Amendment to Lease. Notwithstanding the fact that, upon Tenant’s delivery of an Acceptance Notice or an Arbitration Notice, the renewal of the Lease Term shall be self executing, Landlord and Tenant shall, promptly following
Tenant’s delivery of an Acceptance Notice or an Arbitration Notice, execute one or more amendments to the Lease reflecting such additional term. 
  

	5.	RIGHT OF FIRST REFUSAL. 

 5.1 Grant of Right of First Refusal. Subject to the terms and conditions of this Rider 1, Landlord hereby grants to Tenant a right of first refusal to lease all space in Building B and
Building C of the Project (the “First Refusal Space”). Notwithstanding the foregoing, such right of first refusal shall (a) commence only following the expiration or earlier termination of the initial lease (or leases,
as the case may be) of the First Refusal Space, regardless of whether any such lease is executed prior to or after the Effective Date (including the expiration of any renewal, extension or expansion rights set forth in any such lease, regardless of
whether such renewal, extension or expansion rights are executed strictly in accordance with their terms, or pursuant to a lease amendment or a new lease) and (b) shall be subject and subordinate to the rights granted to HONEYWELL INTERNATIONAL
INC., a Delaware corporation (together with its successors and assigns, the “Superior ROFR Holder”) to lease such First Refusal Space. Tenant’s right of first refusal shall be on the terms and conditions set forth in
this Rider 1.
 5.2 Procedure for Offer. If Landlord receives a bona fide written offer from an unaffiliated third
party for the lease of all or any portion of the First Refusal Space (each, a “Bona Fide Offer”), and Landlord is willing to accept the Bona Fide Offer, Landlord shall give Tenant written notice (the “First Refusal
Notice”) of the Bona Fide Offer including the actual offer agreed to by both parties, but only if the Superior ROFR Holder does not wish to lease such space; provided, however, that Landlord may redact any confidential
information from the actual offer (including the name of the thirty party), or, if Landlord is prohibited from delivering the actual offer, Landlord may only provide a summary of the actual offer. Pursuant to such First Refusal Notice, Landlord
shall offer to lease to Tenant the First Refusal Space on the same terms and conditions of the Bona Fide Offer (collectively, the “Bona Fide Offer Terms”). Landlord shall provide all material terms and conditions of Bona Fide
Offer as part of the First Refusal Notice. 
 5.3 Procedure for Acceptance. If Tenant wishes to exercise
Tenant’s right of first refusal with respect to the space described in the First Refusal Notice, then within five (5) business days after delivery of the First Refusal Notice to Tenant, Tenant shall deliver written

  
 Rider 1-5

 
notice to Landlord of Tenant’s exercise of its right of first refusal with respect to the entire space described in the First Refusal Notice on the Bona Fide Offer Terms. Tenant must elect
to exercise its right of first refusal, if at all, with respect to all of the space offered by Landlord to Tenant in the First Refusal Notice. Tenant may not elect to lease only a portion of the space offered in the First Refusal Notice, even if the
space described in the First Refusal Notice comprises an area larger than the First Refusal Space or an area that does not comprise the entire First Refusal Space. If Tenant does not so notify Landlord within the 5-business day period, then Landlord
shall be free to lease and/or re-lease all or any portion of the First Refusal Space from time to time to anyone to whom Landlord desires on any terms Landlord desires.

portion of the First Refusal Space, and Tenant’s obligation to pay Rent for such First Refusal Space, shall commence upon the date of delivery of the First Refusal Space to Tenant and shall terminate on the date set forth in the First Refusal
Notice. 
 5.5 Limitations. Tenant shall not have the right to lease the First Refusal Space, if, as of the date

5.6 Termination of Right of First Refusal. Subject to Section 5.6 below, the right of first refusal granted herein
shall terminate as to the entire First Refusal Space upon the failure by Tenant to timely exercise its right of first refusal with respect to the entire portion of the First Refusal Space as offered by Landlord in the First Refusal Notice.

 5.7 Reinstated Right. Notwithstanding anything in this Rider 1 to the contrary, in the event the right
of first refusal has terminated because of Tenant’s non-exercise of its rights in accordance with this Rider 1, Tenant’s right of first refusal shall be reinstated with respect to the space contained in the First Refusal Notice if Landlord
intends to offer or accept overall economic terms that are less than [...***...] of the economic terms offered to Tenant in the First Refusal Notice. In such an event, Landlord shall notify (“Reduced Terms Notice”)
Tenant and such Reduced Term Notice shall set forth Landlord’s proposed economic terms and conditions upon which Landlord is willing to lease the First Refusal Space to Tenant (“Reduced Economic Terms”). If Tenant
wishes to exercise its reinstated right of first refusal, Tenant shall, within three (3) business days of Tenant’s receipt of the Reduced Terms Notice, deliver written notice to Landlord of Tenant’s exercise of its right of first
refusal with respect to the entire space described in the Reduced Terms Notice on the Reduced Economic Terms. The Right of First Refusal herein shall continue and remain in effect so long as this Lease is in full force and effect, and shall apply to
any future Bona Fide Offer. All provisions of this Rider 1 shall apply, mutatis mutandis, to any reinstated right of first refusal Tenant may have 
 5.8 Amendment to Lease. If Tenant timely exercises Tenant’s right to lease the First Refusal Space as set forth herein, Landlord and Tenant shall, within fifteen (15) days after
Tenant’s exercise thereof, execute an amendment to the Lease for such First Refusal Space upon the terms and conditions as set forth in the First Refusal Notice and this Rider 1.
