monthly in advance, without notice, in equal installments in the amount of monthly rent specified in the Summary. The first monthly installment due hereunder for the sixth (6th) full month of the Lease Term shall be due and payable upon

Landlord may, from time to time, designate in writing.

 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 Rate Share which is the percentage derived by dividing the approximate Floor Area of the Demised Premises, as initially set forth in the Summary, by the
approximate 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 Rate 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 of the amount of Tenant’s Pro Rate 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 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 may not increase or decrease Floor Area of the Building. Landlord shall be entitled to provide services for the Common Facilities for either the Building or the Project, as Landlord determines from time to time. 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, which will be charged during the Lease Term
in a consistent manner. 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 reasonably and in a consistent manner 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 (defined in Section 5.1); 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 (defined in Section 7.2). Landlord shall provide written notice to Tenant prior to any change in the amount of
the Monthly Deposit. 
 4.8    Intentionally Omitted. 
 4.9    General Provisions as to Monthly Deposits. Landlord may commingle the Monthly Deposits with
Landlord’s own funds. 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. In the event of a transfer by Landlord
of Landlord’s interest in the Demised Premises, Landlord or the property manager of Landlord shall deliver the remaining balance of any Monthly Deposits to the transferee of Landlord’s interest and Landlord and such property manager shall
thereupon be discharged from any further liability to Tenant with respect to such Monthly Deposits. 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 to Tenant’s successor in interest and Landlord shall thereupon be discharged from any further liability with respect to the Monthly Deposits. 
  

 6 

 4.10    Annual Adjustment. Within one hundred twenty
(120) days following the end of each calendar year of the Lease Term, 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 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 Tenant’s option and, except as may be otherwise provided by law, either be paid to Tenant within thirty (30) days or credited against the next Monthly Deposits, Basic Rent, Additional Rent and
other amounts 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 ninety (90) 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 Tenant shall not be thereafter 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 beyond any applicable notice and cure period hereunder of its obligations under
this Lease, then Tenant for a period of thirty (30) days after Tenant’s notice may engage its own certified public accountants (“Tenant’s Accountants”) to verify the accuracy of the Statement objected to by Tenant. During
such thirty (30) period, Tenant’s Accountants 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 in Colorado where Landlord maintains such books and records. Tenant’s Accountants shall enter into a confidentiality agreement with Landlord reasonably satisfactory to Landlord, Tenant and Tenant’s Accountants. 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; provided, however, if it is determined that Tenant was overcharged by five percent (5%) or
more for any calendar year, Landlord shall reimburse Tenant for all reasonable costs of Tenant’s audit of Landlord’s books for such calendar year. All costs incurred by Tenant for Tenant’s Accountants 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 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. Further, Landlord shall furnish Tenant with all tax and insurance bills with the Statement and, upon request from Tenant, any other back-up for the Common Facilities Charges.
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 after 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.

 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, “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 the Project (as the case may be), or any part thereof, or upon any building, improvements or personal property at any time situated thereon. Tenant shall not be
required to pay any increases in Taxes solely due to any sale of the Project, provided that the foregoing shall not limit Tenant’s obligation to pay the full amount of any increases in Taxes resulting from the regular periodic reassessment of
Taxes by the Assessor. 
 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

 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, the Tenant Improvements and all Common Facilities (but not any Changes, fixtures or personal property constructed or owned by Tenant) in the amount of
the full replacement cost thereof, on an all risk basis, from such company, with such deductible and on such other 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 Mortgages (as herein 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 its Pro Rata Share of the cost of any deductible under such Property Insurance, which deductible shall not exceed $25,000 per occurrence. Landlord shall obtain Property Insurance in the full amount of the Tenant
Improvements constructed by Tenant, subject to Tenant providing written notice to Landlord of the amount of any Tenant Improvements in excess of the Tenant Improvement Allowance. 
 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,

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 $2,000,000.00 per occurrence. Such policy shall name
Landlord, its property manager and the Mortgagee (as to which Tenant has been given notice) 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 of 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 with
respect to operations in leased space in the vicinity of the Project in the general business and use, as reasonably requested by Landlord from time to time, including, without limitation, workers compensation insurance (but excluding business
interruption insurance). The commercial general liability policy obtained by Tenant shall not contain any retention or self-insurance provision, unless otherwise approved in writing by Landlord, but may have a deductible not to exceed $25,000 per
occurrence. Tenant may utilize blanket and umbrella coverage to satisfy its insurance requirements. Notwithstanding the foregoing, the proceeds of any casualty insurance carried by Tenant with respect to Tenant’s trade fixtures and personal
property shall be paid to and belong to Tenant.

 6.3    Liability Insurance. Landlord covenants and agrees
to maintain a commercial general liability policy (“Liability Insurance”) covering the Common Facilities of the Project in such amounts, from such company, with such deductible and on such terms and conditions as Landlord deems
appropriate, in its reasonable discretion, from time to time. 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 its Pro Rata Share of the cost of any deductible under the Liability Insurance (which deductible shall not exceed
$25,000 per occurrence). 
 6.4    Waiver of Recovery. Landlord and Tenant 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, or for loss of business revenue or
extra expense arising out of or related to the use and occupancy of the Demised Premises, to the extent of any insurance required to be carried by such party under this Lease. Each party shall, upon obtaining the property damage insurance required
by this Lease, notify the insurance carrier that the foregoing waiver is contained in this Lease and use reasonable efforts to obtain an appropriate waiver of subrogation in the policies. 
 6.5    Cooperation. Landlord and Tenant shall cooperate with each other in the collection of any insurance
proceeds which may be payable in the event of any loss, including execution and delivery of any proof of loss or other action required to such recovery. 
 6.6    Evidence of Insurance. Landlord shall provide evidence of Landlord’s Insurance to Tenant annually, promptly following renewal or replacement thereof. Such

effective date of such ownership transfer (that is susceptible of cure), subject to written notice from Tenant and opportunity to cure for such person as required 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, without affecting Tenant’s rights as to the performance of Landlord’s covenants arising subsequent to such succession with respect to any
continuing default that is curable; (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 holder has not consented in writing. Landlord represents and warrants to Tenant that there is no Mortgage affecting the Property as of the date of this Lease, which consent shall not be unreasonably withheld
or delayed.

 (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 or delayed or conditioned. 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 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 any sublease are subject and subordinate to the provisions of this Lease and such sublessee
shall covenant not to violate the provisions of this Lease or (ii) the reputation of the transferee would unreasonably damage or otherwise impair the value of the Building or (iii) the intended use 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 grounds. Tenant shall reimburse Landlord for all of Landlord’s out-of-pocket costs incurred in connection with any
request for consent to a Transfer, including, without limitation, a reasonable sum for attorneys fees, if incurred. 
  

 19 

 (c) Notwithstanding the foregoing, Landlord shall at Landlord’s option, in the case of
an assignment or sublease for all or substantially all of the remaining Lease Term have the right in lieu of consenting to a Transfer by Tenant, to terminate this Lease as to the portion of the Demised Premises that is the subject of the proposed
Transfer, and to enter into a new lease with the proposed transferee and receive directly from the proposed transferee the consideration agreed to be given by such transferee to Tenant for the Transfer by Tenant. Alternatively, at the request of
Landlord, Tenant shall pay over to Landlord, as Additional Rent, fifty percent (50%) 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 fifty percent (50%) of all consideration received on account of or attributable to any assignment of this Lease in each case after first deducting from such gross profit
or proceeds, all reasonable out-of-pocket expenses incurred by Tenant with respect to such Transfer, including, without limitation, all rent concessions and allowances and the unamortized cost of any Improvements or Changes made by Tenant for such
Transfer. Such costs will include any unamortized costs of any Improvements or Changes made by Tenant prior to such Transfer but specifically benefitting such transferee, other than the Tenant Improvements to the extent of the Tenant Improvement
Allowance. If a partial termination of this Lease occurs as set forth above, all Basic Rent and Additional Rent and Tenant’s Pro Rata Share shall be appropriately adjusted. The provisions of this Section 8.16(c) shall not apply to a
Permitted Transfer. 
 (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. This Section 8.16(d) shall not apply to a Permitted Transfer. 
 (e) Tenant covenants and agrees to pay, as Additional Rent to Landlord any reasonable costs and expenses incurred by Landlord in connection
with such request (including, without limitation, reasonable attorneys’ fees), whether or not the consent of Landlord is given to the Transfer requested by Tenant. When the actual amount of such costs and expenses are known by Landlord, Tenant
shall pay to Landlord such additional actual costs and expenses. The payment of such 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, Tenant shall not be entitled to make a Transfer to any person or entity with whom Landlord or
its Related Parties (as herein defined) negotiated or had contact or to whom Landlord has give, or received therefrom, any written or oral proposal regarding a lease of space in the Building within the six (6) month period preceding
Tenant’s request for such Transfer, provided that Landlord (or its affiliated entities) have other space available in Lafayette Corporate Campus that is reasonably suitable for such prospect’s requirements. Tenant shall not publicly
advertise the rate or other economic terms upon which Tenant is willing to Transfer the Demised Premises, and all other public advertisements of a Transfer shall be subject to the prior written approval of Landlord, which approval shall not be
unreasonably withheld, except that Tenant may circulate marketing brochures by mail or e-mail without Landlord’s consent. Public advertisement shall include, without limitation, the placement or displays of any signs or lettering on or above
the Demised Premises. If at the time of the proposed Transfer Landlord shall have other space available in Lafayette Corporate Campus that is reasonably suitable for such prospect’s requirements, Tenant shall not be entitled to Transfer or
offer to Transfer the Demised Premises to such prospect at a rental rate less than the then-prevailing fair market rental for the Demised Premises with all relevant factors considered. 
  

 20 

 (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 more than fifty percent (50%) of the control or ownership, whether legal or beneficial, in Tenant within a twelve (12) month period. Notwithstanding the
foregoing, Tenant may (i) assign or sublet all or a portion of the Demised Premises to any entity that controls, is controlled by or is under common control with Tenant (an “Affiliate”); (ii) assign this Lease to any entity that
succeeds to the interest of Tenant following a merger of consolidation or a reorganization or recapitalization of Tenant; (iii) assign this Lease to any entity that purchase all or substantially all of the stock or assets of Tenant;
(iv) list the shares of stock of Tenant on any public exchange or otherwise offer the stock of Tenant to the public, or (v) assign this Lease to any entity that purchases all or substantially all of the “Abacus” division of
Tenant (including, without limitation, the operations at the Demised premises) as a going concern, in each case, without Landlord’s prior consent (hereinafter referred to as a “Permitted Transfer”); provided that Tenant shall not be
released from obligation or liability under the Lease, if an assignment, the Affiliate assumes all obligations and liabilities of Tenant under the Lease, and Tenant notifies Landlord in a timely manner, along with copies of such sublease or
assignment, as well as documentation evidencing such relationship or affiliation. Further, if Tenant is a public company, the transfer of shares of Tenant shall not be deemed to be a Transfer. 
 (h) As a condition to Landlord’s consent to a Transfer by Tenant, 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 ten (10) days prior to the effective date of such assignment, and any subtenant shall covenant to Landlord not to violate the
provisions of this Lease as applied to the portion of the Demised Premises so sublet and to attorn to Landlord, at Landlord’s written election, in the event of any termination of this Lease prior to the expiration date of the Lease Term, all of
which shall be in a written instrument reasonably satisfactory to Landlord and furnished to Landlord not later than ten (10) days prior to the effective date of such sublease. 
 8.17    Annual Financial Statements. Tenant covenants and agrees to furnish to Landlord, within fifteen
(15) days after written request thereof from Landlord, copies of the then available annual financial statements of Tenant audited, if requested by Landlord, by a certified public accountant, and agrees that Landlord may deliver any such
financial statements to any existing or prospective Mortgagee or purchaser of the Property (under an executed letter of intent of purchase agreement), provided that Landlord and such other parties agree to keep such information confidential pursuant
to a commercially reasonable form of written confidentiality agreement and provided further that Tenant shall not be required to furnish the financial statements for any calendar year before the date that such financial statements have been
completed, but in no event more than one hundred twenty (120) days following such calendar year. The financial statements shall include a balance sheet as of the end of, and a statement of profit and loss for, the preceding fiscal year of
Tenant and, if regularly prepared by Tenant, a statement of sources and use of funds for the preceding fiscal year of Tenant. 
 8.18    Payment of Income and Other Taxes. Tenant covenants and agrees to pay, as Additional Rent, promptly when due, all taxes, the nonpayment of which might give rise to a lien on the Demised Premises or
Tenant’s interest therein, and to furnish, if requested by Landlord, evidence of such payments. 
  

 21 

 8.19    Estoppel Certificates. Tenant covenants and agrees
to execute, acknowledge and deliver to Landlord, upon 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 been paid; stating the amount of the Monthly Deposits held by Landlord for the then tax and insurance year, stating that, to the best knowledge of Tenant, there exists no defaults by Landlord or Tenant and no event which with the
giving of notice or the passage of time, or both, would constitute such a default (or, if there exists defaults, setting forth the nature thereof); and stating such other matters concerning this Lease as Landlord may reasonably request. Tenant
agrees that such statement may be delivered to and relied upon by any existing or prospective Mortgagee or purchaser of the Property. Tenant agrees that a failure to deliver such a statement within fifteen (15) days after written request from
Landlord shall be conclusive upon Tenant that this Lease is in full force and effect without modification except as may be represented by Landlord; that there are no uncured defaults by Landlord or Tenant under this Lease except as may be
represented by Landlord; and that any representation by Landlord with respect to Basic Rent, the Monthly Deposits and any other permitted matter are true. 
 8.20    Landlord Right to Inspect and Show Premises and to Install “For Sale” Signs. Tenant covenants and agrees that Landlord and the authorized
representatives of Landlord shall have the right to enter the Demised Premises at any reasonable time upon prior verbal notice during ordinary business hours (or at any time and without notice in the event of an emergency) for the purposes of
inspecting, repairing or maintaining the same or performing any obligations of Tenant which Tenant has failed to perform hereunder or for the purposes of showing the Demised Premises to any existing or prospective Mortgagee, purchaser or, in the
last twelve (12) months of the Lease Term, tenant of the Property or the Demised Premises. Tenant covenants and agrees that Landlord may at any time and from time to time place on the grounds of the Property, but not on the exterior of the
Building, a sign advertising the Property or the Demised Premises for sale or, during the last twelve (12) months of the Lease Term, for lease. 
 8.21    Landlord Title to Fixtures, Improvements and Equipment. Tenant covenants and agrees that all fixtures and improvements on the Demised Premises and all equipment
relating to the use and operation of the Demised Premises (as distinguished from operations incident to the business of Tenant), including all plumbing, heating, lighting, electrical and air conditioning fixtures and equipment, whether or not
attached to or affixed to the Demised Premises, and whether now or hereafter located upon the Demised Premises, shall be and remain the property of the Landlord upon expiration of the Lease Term. 
 8.22    Removal of Tenant’s Equipment. Tenant covenants and agrees to remove, at or prior to the
expiration or earlier termination of the Lease Term, all of Tenant’s Equipment, as hereinafter defined. “Tenant’s Equipment” shall mean all moveable equipment, apparatus, machinery, signs, furniture, furnishings and personal
property used in the operation of the business of Tenant (as distinguished from the use and operation of the Demised Premises). If such removal shall injure or damage the Demised Premises Tenant covenants and agrees, at its sole cost and expense, at
or prior to the expiration of the Lease Term, to repair such injury and damage in good and workmanlike fashion and to place the Demised Premises in substantially the same condition as the Demised Premises would have been in if such Tenant’s
Equipment had not been installed. If Tenant fails to remove any of Tenant’s Equipment by the expiration of the Lease Term, Landlord may, at its option, keep and retain any such Tenant’s Equipment or dispose of the same and retain any
proceeds therefrom, and Landlord shall be entitled to recover from Tenant, any costs or expenses of Landlord in removing the same and in restoring the Demised Premises, in excess of the actual proceeds, if any, received by Landlord from disposition
thereof. Tenant releases and discharges Landlord from any and all claims and liabilities of any kind arising out of Landlord’s disposition of Tenant’s Equipment. Notwithstanding anything in this Lease to the contrary, Tenant shall not be
required to remove any raised floor, any cables or wiring of any kind or any kitchen pantry or appliances. 
  

 22 

 8.23    Tenant Indemnification of Landlord. Subject to
Section 6.4 hereof and except to the extent caused by the negligence or willful misconduct of Landlord or its employees or agents, Tenant covenants and agrees to protect, indemnify, defend and save Landlord and Landlord’s managers,
employees, agents, beneficiaries, successors, assigns and other related parties (“Related Parties”) harmless from and against all liability, obligations, claims, damages, penalties, causes of action, costs and expenses, including
attorneys’ fees, imposed upon incurred by or asserted against Landlord or its Related Parties by reason of (a) any accident, injury to or death of any person or loss of or damage to any property occurring on or about the Demised Premises,

use which may be made of, or condition existing upon, the Demised Premises; (d) any improvements, fixtures or equipment upon the Demised Premises; (e) any failure on the part of Tenant or Tenant’s Agents to perform or comply with any
of the provisions, covenants or agreements of Tenant contained in this Lease; (f) any violation of any law, ordinance, order, rule or regulation of governmental authorities having jurisdiction over Tenant or Tenant’s Agents; and
(g) any repairs, maintenance or Changes to the Demised Premises by, through or under Tenant. Tenant further covenants and agrees that, in case any action, suit or proceeding is brought against Landlord or its Related Parties by reason of any of
the foregoing, Tenant shall, at Tenant’s sole cost and expense, defend Landlord in any such action, suit or proceeding. Tenant’s employees, officers, directors, shareholders, managers, members and partners shall have no direct liability
under this Lease; without, however, limiting any other claim against such party at law or in equity. 
 8.24    Landlord Indemnification of Tenant. Subject to Section 6.4 hereof and except to the extent caused by the negligence or willful misconduct of Tenant or Tenant’s Agents, Landlord covenants
and agrees to protect, indemnify, defend and save Tenant harmless from and against all liability, obligations, claims, damages, penalties, causes of action, costs and expenses, including attorneys’ fees, imposed upon, incurred by, or asserted
against Tenant by reason of (a) the negligence or willful misconduct of Landlord and its employees and agents; or (b) a default by Landlord under this Lease, after the lapse of all applicable notice grace and cure periods. Tenant waives
and releases any claims Tenant may have against Landlord or its Related Parties for loss, damage or injury to person or property sustained by Tenant or Tenant’s Agents resulting from any cause whatsoever other than (i) negligence or
willful misconduct of Landlord, or (ii) the default by Landlord in its obligations under this Lease. Notwithstanding anything to the contrary, the indemnification of Tenant by Landlord provided in this Section 8.24 shall be subject to all
waivers, limitations and restrictions otherwise provided in this Lease. Notwithstanding anything to the contrary, Landlord’s liability under this Lease shall be restricted to and Tenant shall look solely to the equity of Landlord in the
Property (or, in the event Tenant is leasing any of the Option Space pursuant to the Expansion Option, the Project), including any insurance proceeds, sale proceeds, finance proceeds, cash accounts and condemnation proceeds, in the event of any
default or liability of Landlord under this Lease, such exculpation of liability to be absolute and without any exception whatsoever. Landlord’s employees, officers, directors, shareholders, managers, members and partners shall have no direct

a transfer by Landlord of the Property or of Landlord’s interest as Landlord under this Lease, Landlord’s successor or assign shall take subject to and be bound by this Lease and in such event, Tenant covenants and agrees that Landlord and
its Related Parties shall be released from all obligations of Landlord under this Lease, except obligations which arose and matured prior to such transfer by Landlord; that Tenant shall thereafter look solely to Landlord’s successor or assign

 8.26    Rules and Regulations. Tenant shall observe and comply with rules and regulations attached hereto
as Exhibit C, which may be reasonably amended from time to time by Landlord by providing written notice thereof to Tenant. Landlord shall not be responsible to Tenant for the failure of any other tenant of the Building to observe or comply with any

based solely on any existing environmental reports, there is no asbestos or Hazardous Materials located in the Demised Premises or the Building in violation of Applicable Law as of the date hereof. Subject to Section 6.4 hereof, and except to

 (h) In the event that there are any Hazardous Substances upon the Demised Premises as of the date hereof and Tenant is not
reasonably able to use the Demised Premises as the result of such pre-existing Hazardous Substance, then Tenant may provide written notice thereof to Landlord. In such event, the Lease shall terminate within thirty (30) days after such notice

such Hazardous Substance at no cost to Tenant, as necessary to allow Tenant to again use the Demised Premises, or prosecute legal action or other appropriate proceedings against the parties responsible for such Hazardous Substance, at no cost to
Tenant, in order to cause such remediation as necessary to allow Tenant to again use the Demised Premises. If Landlord makes such election, then the effective date of such termination shall be extended as long as Landlord is diligently pursuing such
remediation and/or legal action; provided that if Tenant does not believe that Landlord is diligently pursuing such remediation and/or legal action, Tenant shall provide at least thirty (30) days written notice thereof and opportunity to cure
to Landlord. Upon remediation of such Hazardous Substance as herein provided, the exercise of such termination shall be withdrawn and the Lease shall continue in full force and effect. Notwithstanding anything to the contrary, if Tenant has not been
reasonably able to use the Demised Premises as a result of such Hazardous Substance for a period of at least eleven (11) months, then Tenant shall be entitled to provide written notice to Landlord accelerating the effective date of such
termination to a date stated in such notice, which date shall not be earlier than one (1) month after such notice from Tenant; provided that if such remediation is completed in order to allow Tenant to again use the Demised Premises within such
one (1) month period, the exercise shall be deemed withdrawn and the Lease shall continue in full force and effect. 
  

 26 

 IX.    DAMAGE OR DESTRUCTION. 
 9.1    Tenant’s Notice of Damage. If any portion of the Demised Premises shall be damaged or
destroyed by fire or other casualty, Tenant shall give prompt written notice thereof to Landlord (“Tenant’s Notice of Damage”). 
 9.2    Options to Terminate if Damage Substantial. Upon receipt of Tenant’s Notice of Damage, Landlord shall promptly proceed to determine the nature and extent of
the damage or destruction and to estimate the time necessary to repair or restore the Demised Premises. As soon as reasonably possible, Landlord shall give written notice to Tenant stating Landlord’s estimate of the time necessary to repair or
restore the Demised Premises (“Landlord’s Notice of Repair Time”). If Landlord reasonably estimates that repair or restoration of the Demised Premises cannot be completed within two hundred forty (240) days from the time of
Tenant’s Notice of Damage, Landlord and Tenant shall each have the option to terminate this Lease. If, however, the damage or destruction was caused by the international act or omission of Tenant or Tenant’s Agents, Landlord shall have the
option to terminate this Lease if Landlord reasonably estimated that the repair or restoration cannot reasonably be completed within two hundred forty (240) days from the time of Tenant’s Notice of Damage, but Tenant shall not have the
option to terminate this Lease. Any option granted hereunder shall be exercised by written notice to the other party given within thirty (30) days after Landlord’s Notice of Repair Time. If either Landlord or Tenant exercises its option to
terminate this Lease, the Lease Term shall expire ten (10) days after the notice by either Landlord or Tenant exercising such party’s option to terminate this Lease. Following termination of this Lease under the provisions hereof Landlord
shall refund to Tenant such amounts of Basic Rent and Additional Rent theretofore paid by Tenant as may be applicable to the period subsequent to the time of Tenant’s Notice of Damage less the reasonable value of any use or occupation of the
Demised Premises by Tenant subsequent to the time of Tenant’s Notice of Damage. If the Demised Premises are materially damaged during the last twelve (12) months of the Lease Term, such that Landlord reasonably estimates that the repair or
restoration cannot be reasonably completed within one hundred twenty (120) days after the Tenant’s Notice of Damage, then Landlord or Tenant may terminate this Lease by providing written notice thereof to the other party within thirty
(30) days after Tenant’s Notice of Damage. 
 9.3    Option to Terminate if Damage to
Building. {Intentionally Omitted} 
 9.4    Obligations to Repair and Restore. If
repair and restoration of the Demised Premises can be completed within the period specified in Section 9.2, in Landlord’s reasonable estimation, or if neither Landlord nor Tenant terminate this Lease as provided in Sections 9.2, then this
Lease shall continue in full force and effect and Landlord shall proceed forthwith to cause the Demised Premises (including the Tenant Improvements and any improvements constructed by Landlord but excluding any Changes, fixtures and personal
property constructed or owned by Tenant) to be repaired and restored with reasonable diligence and there shall be abatement of Basic Rent and Additional Rent proportionate to the extent of the space and period of time that Tenant is unable to use
and enjoy the Demised Premises. 
  

 27 

 9.5    Application of Insurance Proceeds. The proceeds of
any Property insurance maintained on the Demised Premises by Landlord, other than property insurance maintained by Tenant on fixtures and personal property of and leasehold improvements made by Tenant, shall be paid to and become the property of
Landlord, subject to any obligation of Landlord to cause the Demised Premises and Tenant Improvements to be repaired and restored and further subject to any rights under any Mortgage encumbering the Property to such proceeds. If such fire or other
casualty shall occur during the last two (2) years of the Lease Term (subject to Tenant’s right to exercise the Renewal Option), then Landlord’s obligation to repair and restore the Demised Premises and Tenant Improvements provided in
this Section 9 is limited to the repair and restoration that can be accomplished with the proceeds of any Property Insurance maintained on the Demised Premises, plus the amount of any deductible under the Property Insurance (subject to
Tenant’s reimbursement of such deductible to the extent provided in Section 6.1). The amount of any such insurance proceeds is subject to any right of any Mortgagee to apply such proceeds to its secured debt under its Mortgage. 

X.    CONDEMNATION. 
 10.1    Taking – Substantial Taking – Insubstantial Taking. A “Taking” shall mean the taking of all or any portion of the Demised Premises or the
Building as a result of the exercise of the power of eminent domain or condemnation for public or quasi-public use or the sale of all or part of the Demised Premises or the Building under the threat of condemnation. A “Substantial Taking”
shall mean a Taking of fifteen percent (15%) or more of the Floor Area of either the Demised Premises or the Building, or if any parking is taken and the remainder is not reasonably sufficient for Tenant’s needs. An “Insubstantial
Taking” shall mean a Taking which does not constitute a Substantial Taking. 
 10.2    Termination on Substantial Taking. If there is a Substantial Taking with respect to the Demised Premises or the Building, the Lease Term shall expire on the date of vesting of title pursuant to such
Taking. In the event of termination of this Lease under the provisions hereof, Landlord shall refund to Tenant such amounts of Basic Rent and Additional Rent theretofore paid by Tenant as may be applicable to the period subsequent to the time of
termination of this Lease. 
 10.3    Restoration on Insubstantial Taking. In the event of an
Insubstantial Taking with respect to the Demised Premises or the Building, this Lease shall continue in full force and effect, Landlord shall proceed forthwith to cause the Demised Premises (including the Tenant Improvements but excluding any
Changes, fixtures and personal property constructed or owned by Tenant), less such Taking, to be restored as near as may be to the original condition thereof prior to such Taking and there shall be abatement of Basic Rent and Additional Rent
proportionate to the extent of the space so taken. 
 10.4    Right to Award. The total award,
compensation, damages or consideration received or receivable as a result of a Taking (“Award”) shall be paid to and be the property of Landlord, including, without limitation, any part of the Award made as compensation for diminution of
the value of this leasehold or the fee of the Demised Premises. Tenant hereby assigns to Landlord, all of Tenant’s right, title and interest in and to any such Award. Tenant covenants and agrees to execute, immediately upon demand by Landlord
such documents as may be necessary to facilitate collection by Landlord of any such Award. Notwithstanding Landlord’s right to the entire Award, Tenant shall be entitled to a separate award, if any, for the loss of Tenant’s personal
property, the loss of Tenant’s business and profits. Tenant’s moving expenses, and Changes made by Tenant (subject to amortization of such Changes on a straight line basis over the initial Lease Term). 
  

 28 

 XI.    DEFAULTS BY TENANT. 
 11.1    Defaults Generally. In the event that any of the following events shall occur, Tenant shall be
deemed to be in default of Tenant’s obligations under this Lease (each of the following shall be referred to as a “Default by Tenant”). 
 11.2    Failure to Pay Rent or Other Amounts. A Default by Tenant shall exist if Tenant fails to pay Basic Rent, Additional Rent, Monthly Deposits, or any other amounts

entry and detainer. 
 11.3    Violation of Lease Terms. A Default by Tenant shall exist if
Tenant breaches or fails to comply with any non-monetary agreement, term, covenant or condition in this Lease applicable to Tenant, and Tenant does not cure such breach or failure within thirty (30) days after notice thereof by Landlord to
Tenant, or, if such breach or failure to comply cannot be reasonably cured within such 30 day period, if Tenant shall not in good faith commence to cure such breach on failure to comply within such 20-day period or shall not diligently proceed
therewith to completion following such notice. 
 11.4    Inspection of Demised Premises. A
Default by Tenant shall exist if the Demised Premises is not being occupied and Tenant shall fail to cause the Demised Premises to be inspected or monitored for fifteen (15) consecutive days.

 11.6    Execution and Attachment against Tenant. A Default by Tenant shall exist if Tenant’s interest

not be discharged or disposed of within fifteen (15) days after the levy thereof. 
 11.7    Bankruptcy or Related Proceedings. A Default by Tenant shall exist if Tenant shall file a petition in bankruptcy or insolvency or for reorganization or arrangement under the bankruptcy laws of the

 29 

 XII.    LANDLORD’S REMEDIES. 
 12.1    Remedies Generally. Upon the occurrence of any Default by Tenant, Landlord shall have the right,
at Landlord’s election, then or any time thereafter, to exercise any one or more of the following remedies. 
 12.2    Cure by Landlord. In the event of a Default by Tenant, Landlord may, at Landlord’s option, but without obligation to do so, and without releasing Tenant from any obligations under this Lease,
make any payment or take any action as Landlord may deem necessary or desirable to cure any such Default by Tenant in such manner and to such extent as Landlord may deem necessary or desirable. Landlord may do so without demand on, or written notice
to, Tenant and without giving Tenant an opportunity to cure such Default by Tenant. Tenant covenants and agrees to pay to Landlord, within ten (10) days after demand, all advances, 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 fifteen percent (15%) 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 date of payment of any such advances, costs and expenses by Landlord. Action taken by Landlord may include commencing,
appearing in, defending or otherwise participating in any action or proceeding and paying, purchasing, contesting or compromising any claim, right, encumbrance, charge or lien, with respect to the Demised Premises which Landlord, in its discretion,
may deem necessary or desirable to protect its interest in the Demised Premises and under this Lease. In the event that the Lease 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, which expenses shall be reasonably allocated if the term of the reletting extends beyond the remaining Lease Term. 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 eight percent (8%) per annum. 

 

 30 

 12.4    Repossession and Reletting. In the event of a
Default by Tenant to the extent permitted by applicable law, Landlord may, in accordance with a valid court order therefor, reenter and take possession of the 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. After recovering possession of the Demised Premises, Landlord may, from time to time, but shall not be obligated to, relet the Demised Premises, or any part thereof, for the account of Tenant, for such term or terms and on
such conditions and upon such other terms as Landlord, in its sole and subjective discretion, may determine. Nothing herein provided shall limit Landlord’s obligation to mitigate damages in accordance with Colorado law. Landlord may make such
repairs, alterations or improvements as Landlord may consider appropriate to accomplish such reletting, and Tenant shall reimburse Landlord upon demand for all costs and expenses, including attorneys’ fees, which Landlord may incur in
connection with such reletting, to the extent permitted by applicable law. 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. Upon the expiration or earlier termination of this Lease, Landlord shall 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    Tenant’s Financing. In connection with
any institutional financing arrangement made by Tenant, Landlord will execute and deliver a waiver of any “landlord’s lien” against Tenant’s property, reasonably acceptable to Landlord. 
  

 31 

 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 Landlord in connection with 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 Landlord, shall be paid by Tenant to Landlord within ten (10) days of 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 seventh
(7th) 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 seventh (7th) day of the month next following the month in which Tenant was invoiced, an administrative late charge of four percent (4%) 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. Notwithstanding the foregoing, Tenant shall not be required to pay a late charge with respect to the first
delinquent payment made by Tenant during any Year. 
 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 fifteen percent (15%) per annum, compounded on a monthly basis, on the amount of any Basic Rent, Additional Rent or other
charges not paid when due, from the date due and payable, and on the amount of any payment made by Landlord required to have been made by Tenant under this Lease and on the amount of any costs and expenses, including reasonable attorneys’ fees,
paid by Landlord in connection with the taking of any action to cure any Default by Tenant, from the date of making any such payment or the advancement of such costs and expenses by Landlord. 
 12.10    Additional Damages. In the event of a Default by Tenant, Landlord shall be entitled to recover as
damages, in addition to all other damages and remedies provided hereunder, an amount equal to the total of (i) the cost of recovering possession of the Demised Premises, (ii) the unpaid Basic Rent, Additional Rent and any other amounts
current at the time of such Default by Tenant, or (iii) damages for the wrongful withholding of the Demised Premises by Tenant. Landlord waives all consequential damages and loss of profits against Tenant except with respect to any
(a) holdover, subject to Section 13.2, or (b) material physical damage to the Demised Premises intentionally caused by Tenant or Tenant’s Agents in violation of Tenant’s obligations under this Lease (provided that such
damages shall be reduced to the extent of any insurance proceeds from Landlord’s Insurance and excluding any damage to the extent caused by the negligence of Tenant or Tenant’s Agents). 
  

 32 

 12.11    Landlord’s Bankruptcy Remedies. Nothing
contained in this Lease shall limit or prejudice the right of Landlord to prove and obtain as liquidated damages in any bankruptcy, insolvency, receivership, reorganization or dissolution proceeding an amount equal to the maximum allowable by any
statute or rule of law governing such proceeding in effect at the time when such damages are to be proved whether or not such amount be greater equal or less than the amounts recoverable, either as damages or rent, under this Lease. 
 12.12    Remedies Cumulative. Exercise of any of the remedies of Landlord under this Lease shall not
prevent the concurrent or subsequent exercise of any other remedy provided for in this Lease or otherwise available to Landlord at law or in equity. 
 XIII.    SURRENDER AND HOLDING OVER. 
 13.1    Surrender
Upon Lease Expiration. Upon the expiration or earlier termination of this Lease, or on the date specified in any demand for possession by Landlord after any Default by Tenant, Tenant covenants and agrees to surrender possession of the
Demised Premises to Landlord broom clean and otherwise in similar condition as when Tenant first occupied the Demised Premises after completion of the Tenant Improvements ordinary wear and tear excepted, any Changes made by Tenant excepted, and
damage for which Tenant is not liable under this Lease or the law excepted. Tenant, at Landlord’s option, shall transfer the telephone services to Landlord instead of terminating such service account provided that Landlord bears any costs of
such transfer. If, within the last ninety (90) days of the Lease Term, Tenant has vacated the Demised Premises, Landlord shall have the right to decorate, remodel, repair, or otherwise prepare the Demised Premises for reletting and
re-occupancy. 
 13.2    Holding Over. If Tenant shall hold over after the expiration of the
Lease Term, with or without written consent, Tenant shall be deemed to be a tenant from month to month, at a monthly rental, payable in advance, equal to one hundred fifty percent (150%) of the Basic Rent and Tenant shall also pay all
Additional Rent, 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 may exercise any and all
remedies at law or in equity to recover possession of the Demised Premises, as well as, if Tenant holds over for more than the three (3) month period herein provided without Landlord’s written consent, any damages incurred by Landlord, due
to Tenant’s failure to vacate the Demised Premises and deliver possession to Landlord as herein provided Notwithstanding the foregoing, Landlord consents to Tenant holding over for a period of up to three (3) months at the monthly amount
of Basic Rent and Additional Rent being paid for the month immediately preceding the expiration date of the Lease Term, provided that (a) Tenant provides notice thereof to Landlord at least six (6) months prior to the expiration date of
the Lease Term and (b) there is no Default by Tenant under this Lease. In no event shall Tenant be liable to Landlord for any consequential or other damages for holding over hereunder, except to the extent that Tenant holds over in the Demised
Premises for more than the three (3) month period herein provided without the written consent of Landlord. 
  

 33 

 XIV.    MISCELLANEOUS. 
 14.1    No Implied Waiver. No failure by Landlord or Tenant to insist upon the strict performance of any
term, covenant or agreement contained in this Lease, no failure by Landlord or Tenant to exercise any right or remedy under this Lease, and no acceptance of full or partial payment during the continuance of any Default by Tenant or payment of rent
during a default by Landlord, shall constitute a waiver of any such term, covenant or agreement, or a waiver of any such right or remedy, or a waiver of any such Default by Tenant or default by Landlord, as the case may be.

shall send notice of such default by certified or registered mail, postage prepaid, to any Mortgagee of whose address. Tenant has been notified in writing and shall afford such holder a reasonable opportunity to cure any default on Landlord’s
behalf but in no event less than thirty (30) days following such notice. In no event shall Landlord be responsible for any consequential damages incurred by Tenant including, but not limited to, loss of profits or interruption of business as a

 35 

 14.17    Agency Disclosure. 
 (a) Landlord is represented by Etkin Johnson Company LLC, 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 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    Intentionally Omitted. 
 14.19    Parking. 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 and may modify,
relocate, reduce or restrict any of the parking spaces in the Parking Area, but the same may not be reduced so as to provide Tenant less than the number of spaces set forth in the Summary, Landlord shall be entitled to permit the use of the Parking
Area for other purposes, including uses not related to the operation of the Building, provided the same does not create a insurance to Tenant or interfere with Tenant’s use of the Demised Premises, access thereto or Tenant’s parking
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 of Tenant’s Agents which occurs in or
about the Parking Area. At Tenant’s request and cost, Landlord shall identify visitor parking spaces for Tenant’s guests, which spaces shall be included in the parking spaces allocated to Tenant and located nearest to the entrance to the
Demised Premises. Subject to the other provisions of this Lease, Tenant’s right to use such parking spaces shall be a license only, which license shall be co-terminus with the expiration or any termination of this lease. Landlord shall not
grant parking rights in the Parking Area to Tenant and other parties for more parking spaces than are available in the Parking Area. Landlord shall use good faith efforts to stop any party from using more parking spaces in the Parking Area than the
number to which such party is entitled, at Tenant’s request.

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. 
  

 37 

 14.21    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.

obtaining any economic incentives for Tenant locating at the Project or growing its business at the Project, and Tenant shall be entitled to all of such benefits. The foregoing shall not limit Landlord’s right to obtain any economic incentives
with respect to the Project and Landlord shall be entitled to all of such benefits.

 RECITALS: 
 A.     Contemporaneously herewith, 2650 Crescent LLC (“Related Landlord”) and Tenant are entering into a Lease
of Space, dated December 14, 2005 (as the same may be amended from time to time, the “Related Lease”), pertaining to the demised premises located at 251 Exempla Circle, Lafayette, Colorado 80026 (“Related Premises”).

Addendum to the Related Lease, Related Landlord is required to cause Landlord to grant certain expansion options to Tenant to lease the Option Space (as defined below). 
 C.    Landlord and Tenant desire to enter into this Agreement to provide for Landlord’s grant of certain of such expansion options to Tenant, as more fully herein set forth.

 AGREEMENT: 
 NOW THEREFORE, in consideration of the mutual covenants herein contained and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto hereby agree as follows: 
 1.    Expansion Option. Landlord grants the expansion option and continuous right of first refusal to
Tenant (“Expansion Option”) to lease the Option Space (as herein defined), upon the terms and conditions provided in this Agreement. The “Option Space” shall be all leasable space located in the buildings known as 2600 Campus

 2.    Expansion Space. In the event Landlord desires to accept a bona fide third party offer to lease all
or any portion of the Option Space (herein referred to as the “Expansion Space”), Landlord shall provide Tenant with written notice thereof to Tenant (“First Right of Refusal Notice”). For a period of five (5) business days
after the First Right of Refusal Notice, Tenant shall have the right to lease the entire Expansion Space by providing written notice thereof to Landlord within such five (5) business day period. If Tenant exercises the Expansion Option with
respect to such Expansion Space, Landlord and Tenant shall enter into a lease agreement (“Lease”) for such Expansion Space, upon the terms and conditions herein set forth. 
  

 E-1 

 3.    Lease. Landlord and Tenant shall enter into the

Expansion Option by Tenant. The Lease shall provide for the same terms, conditions, agreements and provisions as the Related Lease to the extent applicable as applied to the Expansion Space, except as follows. 
 (a) If Tenant exercises the Expansion Option with respect to a First Right of Refusal Notice provided within the first eighteen
(18) months of the Lease Term of the Related Premises under the Related Lease, the Basic Rent (exclusive of any increases by reason of Section 3 of the Work Letter attached to the Related Lease, unless Tenant utilizes such additional funds

the Expansion Space shall commence upon the date specified in the First Right of Refusal Notice (or such later date as such Expansion Space is actually delivered to Tenant), and shall be co-terminus with the Lease Term for the Related Premises under
the Related Lease, and the Tenant Improvement Allowance for the Expansion Space shall be prorated based upon the number of months remaining in the initial Lease Term of the Related Premises under the Related Lease, as compared to the total number of

Right of Refusal Notice ends prior to the Lease Term of the Related Premises under the Related Lease, the Tenant Improvement Allowance and other concessions will not be reduced and shall be in the amount set forth in the First Right of Refusal
Notice. 
 (c) The Termination Fee in the Termination Option shall be adjusted as follows: (i) Tenant shall not be required
to pay the fixed amount provided in Section 5(i) of the Addendum to the Related Lease, and (ii) the unamortized leasing costs to be paid by Tenant, as provided in Section 5(ii) of the Addendum to the Related Lease, shall be based upon
the actual leasing costs for the Expansion Space. 
  

 E-2 

 (d) The number of unassigned parking spaces allocated to Tenant, pursuant to Section 13
of the Summary to the Lease, shall be adjusted for the Expansion Space based upon a ratio of 5.0 parking spaces per 1,000 square feet of Floor Area of the Expansion Space. Tenant’s Pro Rata Share, pursuant to Section 6 of the Summary to

 4.    General Provisions. 
 (a) If Tenant fails
to exercise the Expansion Option as to any Expansion Space by failing to provide written notice thereof to Landlord as and when herein specified, Landlord shall have the right to lease the Expansion Space to the original bona fide third party and
Tenant shall have no further Expansion Option with respect to the Expansion Space unless (i) the original bona fide party and Landlord do not consummate a lease transaction, or (ii) the Expansion Space is again available for lease after
the leasing thereof to such bona fide third party, in which event Tenant’s Expansion Option with respect to such Expansion Space shall continue to be in full force and effect. 
 (b) If there is a Default by Tenant under any Lease or the Related Lease at any time between the time that the First Right of Refusal Notice
is required and the time of the commencement date of the Lease Term of any Expansion Space, then at Landlord’s option, the Expansion Option shall be null and void and of no further effect with respect to such Expansion Space at such time.

 (c) The Expansion Option shall be subject to all currently existing leases for the Option Space and all currently existing
options and rights of renewal, expansion, extension or refusal affecting the Option Space. Therefore, Tenant shall have no option with regard to any portion of the Option Space which is currently leased or subject to a currently existing grant of
any such options or rights by Landlord until termination or expiration of such lease and/or the lapse or expiration of any such options or rights. 
 (d) The Expansion Option is personal to Tenant and to any successor transferee of a Permitted Transfer (as defined in Related Lease) and in the event of any Transfer other than a Permitted Transfer by

Lease shall have the following additional terms:

pay rentals under the Lease shall not be delayed or affected and Landlord shall not be liable in any manner whatsoever to Tenant for such delay in giving Tenant early occupancy. Tenant acknowledges and accepts the risk of such occupancy during the

agents.

and shall be null and void and the Lease shall continue in full force and effect in accordance with the terms and conditions thereof. The Termination Option shall be personal to Tenant and any successor or transferee to a Permitted Transfer and in
the event of a Transfer by Tenant other than a Permitted Transfer, the Termination Option shall apply only to the initial Lease Term and shall not be effective during any Option. Term or any other extensions or renewals thereof. The
“Termination Fee” shall mean the amount equal to (i) $140,231.00; plus (ii) an amount equal to the number of calendar months remaining in the Lease Term after the effective date of such termination divided by the number of
calendar months, the original Lease Term and then multiplying such result by the sum of all costs of Landlord in entering into the Lease including, without limitation, the cost of the Tenant Improvement Allowance paid by Landlord and all real estate
brokers’ commissions paid by Landlord. If Tenant fails to exercise the Termination Option as and when herein provided, the Termination Option shall be null and void and of no further force of effect. 
 6.    Option to Extend. Landlord grants to Tenant the right to extend the Lease Term (“Renewal
Option”) for two (2) successive periods of up to seven (7) years each (“Option Term”), upon the following terms and conditions. 
 (a) Tenant must exercise each Renewal Option, if at all by providing Landlord with written notice thereof at least nine (9) months but not more than twenty four (24) months prior to the
expiration date of the then-current Lease Term (“Renewal Notice”), which Renewal Notice shall specify the length of the Option Term. The Option Term may not be less than five (5) years and if Tenant fails to specify the Option Term in
the Renewal Notice, the Option Term shall be deemed to be seven (7) years. If Tenant does not provide Landlord with the Renewal Notice as and when herein specified, the Renewal Option shall terminate and be of no further force or effect. If
Tenant exercises a Renewal Option, the Lease Term shall be extended for an additional period determined as provided above, upon the same terms and conditions as set forth in the Lease, except the Basic Rent and this Renewal Option. The Basic Rent
for such Option Term shall be at ninety-five percent (95%) of the then-current “Market Rate” as defined below. Each of the two (2) Renewal Options may be exercised only once and once exercised, such Renewal Option shall not be
effective during any subsequent Option Term. 
  

 ADD-2 

 (b) The Renewal Option shall apply to the entire Demised Premises, as amended or expanded as
of the commencement date of each Option Term, and may not be exercised only as to a portion of the Demised Premises, Upon exercise of a Renewal Option, Landlord and Tenant shall enter into an amendment to the Lease memorializing the terms and
conditions of the Lease during such Option Term. If there is a Default by Tenant at any time between the date it exercises a Renewal Option and the date upon which such Option Term is to commence, then Landlord at its option may elect to treat the
exercise of such Renewal Option as ineffective in which case this Lease shall terminate upon expiration of the then-current Lease Term. 
 (c) The Renewal Option is personal to Tenant and to any successor transferee under a Permitted Transfer and in the event of any Transfer by Tenant, other than a Permitted Transfer, whether or not with the
consent of Landlord, any Renewal Options which have not been exercised as of the date of such Transfer shall automatically terminate. 
 (d) The “Market Rate” means the rate at which Landlord under no compulsion to lease the Demised Premises and a tenant under no compulsion to renew a lease for the Demised Premises would determine as the rental (including initial
monthly rental and rental increases) for the renewal Option, as of the commencement date of such Option Term, taking into consideration the uses permitted under the Lease, the quality, size, design and location of the Demised Premises, and the
rental for the renewal of leases for comparable space located in the vicinity and taking into account all relevant factors, including that Tenant will receive no rent abatement or other concessions. During the Option Term, Tenant shall not be
entitled to any abatement of any rentals or rental concessions that are then being offered by Landlord or other property owners. 
 (e) If Tenant provides the Renewal Notice, Landlord will notify Tenant of the Market Rate for the Option Term (“Landlord’s Rate”) within twenty (20) days after receiving the Renewal Notice. If Tenant does not agree that
Landlord’s Rate is the Market Rate, Tenant shall provide written notice thereof to Landlord within ten (10) days after Landlord’s notice, indicating the rental rate that Tenant asserts as the Market Rate for the Option Term
(“Tenant’s Rate”). If Tenant fails to provide notice within such ten (10) day period, Tenant shall be deemed to have accepted Landlord’s Rate as the Market Rate. If Tenant timely provides such notice, then each party shall,
within ten (10) days after Landlord receives Tenant’s notice of such dispute, designate by written notice to the other party one (1) licensed Colorado real estate broker with appropriate experience and of good reputation, having at
least five (5) years’ experience in the Broomfield and Boulder County real estate market (“Brokers(s)”). The two Brokers so designated shall together determine whether Landlord’s Rate or Tenant’s Rate is closest to the
Market Rate for the space in question. Landlord and Tenant shall each require the Brokers to make such determination and report it in writing to Landlord and Tenant within twenty (20) days after such selection, and each party shall use its best
efforts to secure such determination within such time period. If the two selected Brokers agree as to which rate is closest, the rate agreed to be the closest (either Landlord’s Rate or Tenant’s Rate) shall be deemed the effective rental
rate. The two selected Brokers fail to agree pursuant to this procedure, they shall together immediately select a third Broker who shall then (within ten (10) days of the Brokers’ selection) determine which rate is closed to the Market
Rate as determined by the third Broker. The third Broker shall notify Landlord and Tenant of the Brokers determination and the rental rate selected shall be the effective rental rate. Each party will pay the fee of the Broker selected by it and one
half (1/2) of the fee of the third Broker. 
  

 ADD-3 

 (f) Landlord and Tenant acknowledge that if in the future Landlord and Tenant enter into an
amendment to the Lease providing for the extension of the Lease Term for at lease four (4) years, then such extension shall be in substitution and replacement of one (1) of the Option Terms hereunder, whether such extension is for a longer
or shorter period and irrespective of whether or not so specified in such amendments. In such event Tenant shall have one less Renewal Option hereunder. 
 7.    Expansion Options.

cause to be granted to Tenant the expansion option and continuous right of refusal in accordance with the Lease Option Agreement attached hereto as Exhibit E (“Option Agreement”), with respect to the Option Space described in the Option

 1.    Preliminary Plans/Working Drawings. 
 (a)    Landlord and Tenant
designate McDermott Planning & Design, Inc. (the “Architect”) as the architect for the construction of the Tenant Improvements (as herein defined). Tenant, at Tenant’s discretion, shall have the right to competitively bid the
Tenant Improvements with at least three mutually acceptable, qualified tenant finish contractors. Tenant shall select the most qualified bid and tenant finish contractor, in its sole discretion. Tenant shall have the right to select its own
construction manager. Landlord shall be entitled to reasonably approve all such selections and the form and substance of the written agreements with all such contractors. Landlord shall not be permitted to specify a particular subcontractor unless
Landlord is willing to pay any increased charge therefor; however, without limiting Landlord’s right hereunder to reasonably disapprove of any subcontractor. 
 (b)    Landlord and Tenant shall consult and cooperate with each other as necessary to reach agreement regarding schematic designs, performance requirements and preliminary plans for
the Tenant Improvements (“Preliminary Plans”). The Architect shall prepare the Preliminary Plans and provide the Preliminary Plans to Landlord and Tenant for approval. Landlord and Tenant shall review the Preliminary Plans and provide
written notice to the Architect and the other party of any objection to the Preliminary Plans, specifying any changes required for such party’s approval, which shall not be unreasonably withheld or conditioned. If Landlord does not provide
written notice of objection within five (5) business days after receipt of the Preliminary Plans, Landlord shall be deemed to have approved the Preliminary Plans. 
 (c)    Upon approval of the Preliminary Plans, Landlord and Tenant shall consult and cooperate with each other as necessary to reach agreement regarding the complete construction and
engineering plans and specifications for the construction of the Tenant Improvements (the “Working Drawings”), including, without limitation, a budget for the cost of the construction of the Tenant Improvements. The Working Drawings shall
be prepared by the Architect and shall be an evolution and incorporation of the Preliminary Plans. The Architect shall provide the Working Drawings to the Landlord and Tenant for approval. Landlord and Tenant shall review the Working Drawings and
provide written notice to the Architect and the other party of any objection to the Working Drawings, specifying any changes required for such party’s approval of the Working Drawings, which shall not be unreasonably withheld or conditioned. If

Working Drawings, as the case may be, as soon as reasonably possible and submit a revised draft thereof to Landlord and Tenant for approval. The same procedures and deadlines for review and approval by Landlord and Tenant shall apply to the revised
draft. Landlord’s approval of the Preliminary Plans or the Working Drawings shall not constitute any opinion or agreement by Landlord or impose any present or future liability or responsibility on Landlord, except as expressly herein set forth.

Improvements are less than the Tenant Improvement Allowance, the cost savings shall belong to Landlord and Tenant shall not be entitled to any payment, refund, credit or reduction in Basic Rent or other charges due under the Lease. If the costs of
the Tenant Improvements exceed the Tenant Improvement Allowance, Tenant shall have the right to require Landlord to pay up to an additional $6.00 per square foot of the Floor Area of the Demised Premises for the costs of the Tenant Improvements, as

amount at an interest rate of eight percent (8%) per annum over the Lease Term. In such event, Landlord and Tenant shall enter into an amendment to the Lease memorializing the increase in the Tenant Improvement Allowance and the Basic Rent.

 LEASE OPTION AGREEMENT 
 THIS LEASE OPTION AGREEMENT is made this 14th day of December, 2005 (“Agreement”), between
2600 CAMPUS DRIVE LLC, a Colorado limited liability company (“Landlord”), and DOUBLECLICK INC., a Delaware corporation (“Tenant”). 
 RECITALS 
 A.    Contemporaneously herewith 2650 Crescent LLC
(“Related Landlord”) and Tenant are entering into a Lease of Space, dated December 14, 2005 (as the same may be amended from time to time the “Related Lease”), pertaining to the demised premises located at 251 Exempla
Circle, Lafayette, Colorado 80026 (“Related Premises”). 
 B.    In satisfaction of certain of
Related Landlord’s obligations under Section 7 of the Addendum to the Related Lease Related Landlord is required to cause Landlord to grant certain expansion options to Tenant to lease the Option Space (as defined below). 
 C.    Landlord and Tenant desire to enter into this Agreement to provide for Landlord’s grant of certain of such
expansion options to Tenant, as more fully herein set forth. 
 AGREEMENT: 
 NOW THEREFORE, in consideration of the mutual covenants herein contained and for other good and valuable consideration the receipt and
sufficiency of which is hereby acknowledged, the parties hereto hereby agree as follows: 
 1.    Expansion Option. Landlord grants the expansion option and continuous right of first refusal to Tenant (“Expansion Option”) to lease the Option Space (as herein defined), upon the terms and
conditions provided in this Agreement. The “Option Space” shall be all leasable space located in the buildings known as 2600 Campus Drive 2655 Crescent Drive and 2675 Crescent Drive, Lafayette, Colorado 80026, owned by Landlord from time
to time. The Option Space is more fully described on Exhibit A attached hereto and incorporated herein. 
 2.    Expansion Space. In the event Landlord desires to accept a bona fide third party offer to lease all or any portion of the Option Space (herein referred to as the “Expansion Space”). Landlord shall
provide Tenant with written notice thereof to Tenant (“First Right of Refusal Notice”). For a period of five (5) business days after the First Right of Refusal Notice, Tenant shall have the right to lease the entire Expansion Space by
providing written notice thereof to Landlord within such five (5) business day period. If Tenant exercises the Expansion Option with respect to such Expansion Space, Landlord and Tenant shall enter into a lease agreement (“Lease”) for
such Expansion Space, upon the terms and conditions herein set forth. 

 3.    Lease. Landlord and Tenant shall enter into the Lease for
such Expansion Space within thirty (30) days after Tenant’s exercise of the Expansion Option with respect to such Expansion Space. Landlord and Tenant shall enter into a separate Lease with respect to each exercise of the Expansion Option
by Tenant. The Lease shall provide for the same terms, conditions, agreements and provisions as the Related Lease to the extent applicable, as applied to the Expansion Space, except as follows: 
 (a)    If Tenant exercises the Expansion Option with respect to a First Right of Refusal Notice provided within the
first eighteen (18) months of the Lease Term of the Related Premises under the Related Lease, the Basic Rent (exclusive of any increases by reason of Section 3 of the Work Letter attached to the Related Lease, unless Tenant utilizes such
additional funds with respect to such Expansion Space) shall be the same rate per square foot of Floor Area per annum then in effect for the Related Premises (including subsequent annual increases as defined in the Summary of the Related Lease), the
Lease Term for the Expansion Space shall commence upon the date specified in the First Right of Refusal Notice (or such later date as such Expansion Space is actually delivered to Tenant), and shall be co-terminus with the Lease Term for the Related
Premises under the Related Lease, and the Tenant Improvement Allowance for the Expansion Space shall be prorated based upon the number of months remaining in the initial Lease Term of the Related Premises under the Related Lease, as compared to the
total number of months in the initial Lease Term under the Related Lease (which is one hundred twenty (120) months). The construction of the Tenant Improvements for the Expansion Space shall be subject to the terms and conditions provided in
the Work Letter to the Related Lease. 
 (b)    If Tenant exercises the Expansion Option with respect to a
First Right of Refusal Notice provided after the first eighteen (18) months of the Lease Term of the Related Premises under the Related Lease, the First Right of Refusal Notice shall include the Basic Rent, the Lease Term, Tenant Improvement
Allowance, if any, and the other terms and conditions upon which Landlord is willing to lease the Expansion Space to a bona fide third party. If Tenant exercises the Expansion Option with respect to a First Right of Refusal Notice provided after the
first eighteen (18) months of the Lease Term of the Related Premises under the Related Lease, the terms and conditions specified in the First Right of Refusal Notice shall apply; provided, however, the Lease Term of the Expansion Space shall be
co-terminus with the Lease Term for the Related Premises under the Related Lease and any Tenant Improvement Allowance and other concessions shall be prorated based upon the number of months remaining in the initial Lease Term of the Related Premises
under the Related Lease as compared to the total number of months in the Lease Term for which Landlord is willing to lease the Expansion Space to such third party (as stated in the First Right of Refusal Notice). Notwithstanding the foregoing, if
the Lease Term provided in the First Right of Refusal Notice ends prior to the Lease Term of the Related Premises under the Related Lease, the Tenant Improvement Allowance and other concessions will not be reduced and shall be in the amount set
forth in the First Right of Refusal Notice. 
 (c)    The Termination Fee in the Termination Option shall be
adjusted as follows: (i) Tenant shall not be required to pay the fixed amount provided in Section 5(i) of the Addendum to the Related Lease; and (ii) the unamortized leasing costs to be paid by Tenant, as provided in
Section 5(ii) of the Addendum to the Related Lease, shall be based upon the actual leasing costs for the Expansion Space. 
  

 2 

 (d)    The number of unassigned parking spaces allocated to Tenant,
pursuant to Section 13 of the Summary to the Lease, shall be adjusted for the Expansion Space based upon a ratio of 5.0 parking spaces per 1,000 square feet of Floor Area of the Expansion Space. Tenant’s Pro Rata Share, pursuant to
Section 6 of the Summary to the Lease, shall be adjusted for the Expansion Space based upon the Floor Area of the Expansion Space as compared to the Floor Area of the Building and Project, respectively, of which the Expansion Space is a part.
The Lease shall not contain the Rental Abatement provided in Section 2 of the Addendum to the Related Lease. The Lease shall not contain the Expansion Option provided in Section 7 of the Addendum to the Related Lease. 
 (e)    The definition of the Project, pursuant to Section 2.7 of the Lease, shall be the real property comprising
all of the Option Space. The Lease shall also contain the modifications to the Related Lease shown on the marked copy attached as Exhibit B and incorporated herein. 
 4.    General Provisions. 
 (a)    If Tenant fails to exercise the Expansion Option as to any Expansion Space by failing to provide written notice thereof to Landlord and when herein specified, Landlord shall have the right to lease the Expansion
Space to the original bona fide third party and Tenant shall have no further Expansion Option with respect to the Expansion Space unless (i) the original bona fide party and Landlord do not consummate a lease transaction, or (ii) the
Expansion Space is again available for lease after the leasing thereof to such bona fide third party, in which event Tenant’s Expansion Option with respect to such Expansion Space shall continue to be in full force and effect. 
 (b)    If there is a Default by Tenant under any Lease or the Related Lease at any time between the time that the First
Right of Refusal Notice is required and the time of the commencement date of the Lease Term of any Expansion Space, then at Landlord’s option, the Expansion Option shall be null and void and of no further effect with respect to such Expansion
Space at such time. 
 (c)    The Expansion Option shall be subject to all currently existing leases for the
Option Space and all currently existing options and rights of renewal, expansion, extension or refusal affecting the Option Space. Therefore, Tenant shall have no option with regard to any portion of the Option Space which is currently leased or
subject to a currently existing grant of any such options or rights by Landlord until termination or expiration of such lease and/or the lapse or expiration of any such options or rights. 
 (d)    The Expansion Option is personal to Tenant and to any successor transferee of a Permitted Transfer (as defined in
Related Lease) and in the event of any Transfer other than a Permitted Transfer by Tenant, whether or not with the consent of Landlord, the Expansion Option shall automatically terminate and be of no further force or effect. This Expansion Option
shall not be effective during any term that Tenant is a holdover tenant or a tenant at will or sufferance. 
  

 3 

 5.    Termination. The Expansion Option shall lapse at the end of
the ninth (9th) year of the Lease Term of the Related Premises under the Related Lease and Tenant shall have no further right to exercise the Expansion Option thereafter (except with respect to any First Right of Refusal Notice provided prior
to such date). Following the date of such lapse of the Expansion Option, Landlord shall not be required to provide the First Right of Refusal Notice to Tenant. In addition, in the event that the Related Lease expires or is terminated for any reason,
this Expansion Option shall be of no further force or effect and this Agreement shall terminate as of the effective date of such termination of the Related Lease. In the event of the lapse or termination of this Expansion Option or this Agreement,
Landlord and Tenant shall enter into any agreements or instruments reasonably requested by the other party to evidence such termination including, without limitation, a termination of any recorded memorandum memorializing this Expansion Option.

 6.    Notices. All notices and demands under this Agreement shall be in writing, signed by the
parties giving the same and shall be deemed properly given and received when personally delivered, or three (3) business days after mailing through the United States Mail, postage prepaid, certified or registered, return receipt requested, or

 GUARANTY 
 THIS GUARANTY is given as of the 1st day of February, 2007, by ALLIANCE DATA SYSTEMS CORPORATION, a Delaware corporation (“Guarantor”), to and
for the benefit of the below described Landlord. 
 WITNESSETH: 
 WHEREAS, 2650 CRESCENT LLC, a Colorado limited liability company, as landlord (“Landlord”), and DOUBLECLICK, INC., a Delaware
Corporation, as tenant (“Assignor”), entered into a Lease of Space, dated December 14, 2005 (“Lease”), pertaining to the Premises located at 251 Exempla Circle in Lafayette, Colorado (“Demised Premises”).

 WHEREAS, effective February 1, 2007, ALLIANCE DATA FHC, INC., a Delaware corporation (“Assignee”), succeeded
to the interest of Assignor as Tenant under the Lease, pursuant to the Assignment and Assumption Agreement (“Assignment”), dated as of February 1, 2007, between Assignor and Assignee. 
 WHEREAS, Assignor, Assignee and Guarantor have requested Landlord’s release of Assignor under the Lease pursuant to the terms and
conditions of the Assignment, and offered to Landlord a guaranty by Guarantor in substitution and replacement thereof. 
 WHEREAS, Landlord is willing to consent to the Assignment and the release of Assignor pursuant to the Assignment on condition of receiving this Guaranty from Guarantor as herein contained. Capitalized terms not otherwise defined herein
shall have the meanings attributed to such terms in the Lease. 
 NOW, THEREFORE, for and in consideration of Landlord
consenting to the Assignment and agreeing to the release of Assignor pursuant to the Assignment, which Assignment is executed concurrently herewith, and for other good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged by Guarantor, Guarantor hereby agrees as follows: 
 1.    Guarantor hereby unconditionally and
irrevocably, guarantees the full and prompt payment to Landlord of all installments of Basic Rent, Additional Rent, and all other sums due to Landlord pursuant to the terms and provisions of the Lease. Guarantor does hereby waive each and every
notice to which Guarantor may be entitled under the Lease or otherwise, and expressly consents to any extension of time, leniency, modification, waiver, forbearance, or any change which may be made to any term and condition of the Lease, and no such
change, modification, extension, waiver, or forbearance shall release Guarantor from any liability or obligation hereby incurred or assumed. Guarantor further expressly waives any notice of default in or under any of the terms of the Lease, notice
of acceptance of the Guaranty, and all setoffs and counterclaims; provided, however, Guarantor shall be given the same right to cure Tenant’s default as that afforded Tenant under the Lease. 

 2.    It is specifically understood and agreed that, in the event of a
Default by Tenant under the Lease, Landlord shall be entitled to commence any action or proceeding against Guarantor or otherwise exercise any available remedy at law or in equity to enforce the provisions of this Guaranty without first commencing
any action or otherwise proceeding against Tenant or otherwise exhausting any or all of its available remedies against Tenant, it being expressly agreed by the undersigned that its liability under this Guaranty shall be primary, Landlord may
maintain successive actions for other defaults. Landlord’s rights hereunder shall not be exhausted by its exercise of any of its rights or remedies or by any such action, until and unless all obligations hereby guaranteed have been paid and
fully performed. 
 3.    If any action is commenced by Landlord to enforce the provisions of this Guaranty,
Landlord shall be entitled, if it shall prevail in any such action or proceeding, to recover from Guarantor all reasonable costs incurred in connection therewith, including reasonable attorneys’ fees. No payment by Guarantor shall entitle
Guarantor, by subrogation or otherwise, to any payment by Tenant under or out of the property of Tenant, including specifically, but not limited to, the revenues derived from the Demised Premises, except after payment in full to Landlord of all
amounts due and payable by Tenant to Landlord pursuant to the Lease. 
 4.    Guarantor represents, warrants
and acknowledges that Guarantor is financially interested in Assignee. 
 5.    The liability of Guarantor
hereunder shall in no way be affected by, and Guarantor expressly waives any defenses that may arise by reason of (a) the release or discharge of Tenant in any creditors, receivership, bankruptcy or other proceeding; (b) the impairment,
limitation or modification of the liability of Tenant or the estate of Tenant in bankruptcy, or of any remedy for the enforcement of Tenant’s said liability under the Lease, resulting from the operation of any present or future provision of the
National Bankruptcy Act or other statute or from the decision in any court; (c) the rejection or disaffirmance of the Lease in any such proceedings; (d) the modification, assignment or transfer of the Lease by Tenant; (e) any
disability or other defenses of Tenant; or (f) the cessation from any cause whatsoever of the liability of Tenant. 
 6.    Guarantor agrees that if Tenant shall become insolvent or shall be adjudicated as bankrupt, or shall file a petition for reorganization, arrangement or similar relief under any present or future provisions of the
Federal Bankruptcy Code or any similar law or statute of the United States or any State thereof, or if such a petition filed by creditors of Tenant shall be approved by any court, or if Tenant shall seek a judicial readjustment of the rights of its
creditors under any present or future Federal or State law, or if a receiver of all or part of its property and assets is appointed by any State or Federal Court, then: 
 (a) If the Lease shall be terminated or rejected, or the obligations of Tenant thereunder shall be modified, Landlord shall be entitled to recover from the Guarantor and the Guarantor shall pay to
Landlord that which Landlord would be entitled to recover from Tenant under the Lease in the event of a termination of the Lease by Landlord because of a Default by Tenant, and such shall be recoverable from the undersigned without regard to whether
Landlord is entitled to recover the same from Tenant in any such proceeding.

 (b) If any obligation under the Lease is paid by Tenant and all or any part of such monetary
obligation is subsequently avoided or recovered from Landlord as a preference, fraudulent transfer or otherwise, in any bankruptcy, insolvency, liquidation, reorganization or other proceeding involving Tenant, the liability of Guarantor under this
Guaranty shall remain in full force and effect. 
 (c) As further security for the payment of amounts under this Guaranty,
Guarantor shall file all claims against Tenant upon any indebtedness of Tenant to the undersigned in any bankruptcy or other proceeding in which the filing of claims is required by law and shall assign to Landlord all rights of the undersigned

Landlord the full amount thereof, and, to the full extent necessary for that purpose, Guarantor hereby assigns to Landlord all of Guarantor’s rights to any such payments or distributions to which Guarantor would otherwise be entitled.
