4.01.Annual Rent. Subject to the terms and conditions of this Lease, Tenant shall pay to Landlord Annual Rent for the Premises in monthly installments as described below, and each installment of Annual Rent shall be due on the first day of each calendar month without notice or setoff as follows:

*Commencing month 19 through the remainder of the Term based on 37,710 rsf.

Notwithstanding the Rent Concession Period, Tenant agrees that its obligation to pay the Annual Rent and Occupancy Costs (as described hereafter) payments abated hereunder during the Rent Concession Period, and on the abated Annual Rent and Occupancy Costs during months 8 through 18 of the

Term for the partial Premises shall continue throughout the Term of the Lease; provided, however, that such amounts shall only become due and payable if Tenant commits an Event of Default and Landlord commences an action to recover Rent and/or possession of the Premises. If an Event of Default exists hereunder pursuant to Article 19.00, after any cure period and Landlord commences an action to recover Rent and/or possession of the Premises, then the unamortized portion (amortized on a straight line basis commencing from the expiration of the Rent Concession Period over the remaining Term of the Lease; i.e. 84 months) of abated Annual Rent and Occupancy Costs payments not collected by Landlord during the Rent Concession Period shall, as of the date of such Event of Default, become immediately due and payable with interest on such sums at the lesser of one and one-half percent (1.5%) per month or the maximum rate permitted by law from the date of the Event of Default. Annual Rent during the Rent Concession Period shall be calculated at $21.00 per rentable square foot of space in the Premises. Occupancy Costs during the Rent Concession Period shall be calculated in accordance with the Lease. Tenant’s obligation for payment of abated Annual Rent and Occupancy Costs not collected during the Rent Concession Period (which shall only apply if Tenant commits an Event of Default beyond any applicable notice and cure period and Landlord commences an action to recover Rent and/or possession of the Premises) shall be independent of and in addition to Landlord’s other damages pursuant to Article 19.00 of the Lease.

If the Commencement Date is other than the first day of a calendar month, the monthly installment of Annual Rent for the month in which the Commencement Date occurs shall be prorated on a daily basis in accordance with the procedure set forth in Section 4.05.

4.02.Occupancy Costs. Subject to the Rent Concession Period, during which all Occupancy Costs shall be abated, Tenant shall pay to Landlord, at the times and in the manner provided in Section 4.06, the Occupancy Costs determined under Exhibit B; provided however, Occupancy Costs (a) for months 8 through 13 shall be based on 20,000 rentable square feet, and (b) for months 14 through 18 shall be based on 26,000 rentable square feet. Notwithstanding the foregoing, any increase to Occupancy Costs in any Fiscal Year shall be limited to five percent (5%) (on a cumulative basis) annually over the Occupancy Costs paid during the prior Fiscal Year, which limit shall not apply to (i) Taxes, (ii) insurance, (iii) utilities, (iv) snow removal, and (v) any increase directly caused by government regulation, excluding any cost to bring into compliance a current violation of any regulation as of the Effective Date.

4.03.Other Charges. Tenant shall pay to Landlord, at the times and in the manner provided in this Lease or, if not so provided, as reasonably required by

Landlord, all amounts (other than those payable under Sections 4.01 and 4.02) which are payable by Tenant to Landlord under this Lease.

4.04.Payment of Rent - General. All amounts payable by Tenant to Landlord under this Lease shall be deemed to be Rent and shall be payable and recoverable as Rent in the manner herein provided, and Landlord shall have all rights against Tenant for default in any such payment as in the case of arrears of Rent as is more particularly hereinafter provided. Rent shall be paid to Landlord, without deduction or set-off (except as otherwise provided in this Lease), in legal tender of the jurisdiction in which the Building is located, at the address of Landlord as set forth in the beginning of this Lease, or to such other person or at such other address as Landlord may from time to time designate in writing. Tenant’s obligation to pay Rent for the entire Term shall survive the expiration or earlier termination of this Lease (excepting Tenant’s exercise of the Termination Option provided in Article 26.00) and is independent of any covenant or obligation of Landlord hereunder.

4.05.Annual Rent - Partial Month. If the Term begins or ends on a day other than the first or last day of a calendar month, the installment of Annual Rent payable for such partial calendar month of the Term shall be that proportion of the Annual Rent which the number of days from the first day of such partial calendar month to the last day of the partial calendar month bears to 365 days.

4.06.Payment - Occupancy Costs.

(a)Prior to the Commencement Date and the beginning of each Fiscal Year thereafter, Landlord shall compute and deliver to Tenant a bona fide estimate of Occupancy Costs for the appropriate Fiscal Year and without further notice Tenant shall pay to Landlord in monthly installments onetwelfth of such estimate simultaneously with Tenant’s payments of Annual Rent during such Fiscal Year. Any failure by Landlord to deliver any such estimate as aforesaid shall not relieve Tenant of its obligation to pay Occupancy Costs as herein provided. If at any time it reasonably appears to Landlord that the Occupancy Costs for the current Fiscal Year will vary from Landlord’s estimate then Landlord may reasonably readjust the Occupancy Costs for such Fiscal Year by notice delivered to Tenant, and subsequent payments by Tenant for such Fiscal Year will be based upon such readjusted Occupancy Costs.

(b)Unless delayed by causes beyond Landlord’s reasonable control, Landlord shall deliver to Tenant within 120 days after the end of each Fiscal Year a written statement (the “Statement”) setting out in

reasonable detail the amount of Occupancy Costs for such Fiscal Year and certified to be correct by a representative of Landlord. If the aggregate of monthly installments of Occupancy Costs actually paid by Tenant to Landlord during such Fiscal Year differs from the amount of Occupancy Costs payable for such Fiscal Year under Section 4.02 as indicated in the Statement, then, as the case may be, Tenant shall pay the difference to Landlord or Landlord shall issue a credit to Tenant against the Rent remaining to be paid hereunder for the difference, or if no Rent then remains to be paid, refund the difference to Tenant, without interest, within 30 days after the date of delivery of the Statement.

(c)If Tenant disagrees with the accuracy of Occupancy Costs as set forth in the Statement or in any adjustment thereto made by Landlord pursuant to subsection 4.06(d), Tenant shall be required to give Landlord written notice thereof within ninety (90) days after the date Landlord gives Tenant the Statement or notice of adjustment thereto, as the case may be, or Tenant shall conclusively be deemed to have accepted the accuracy of the Statement, or modification thereto, as the case may be, and to have waived any right to claim any readjustment in connection therewith. If Tenant so disagrees with the Statement, or modification thereto, as the case may be, and gives such notice to Landlord, Tenant shall nevertheless make payment in accordance with any notice given by Landlord, but the disagreement shall be referred by Landlord for prompt decision by a mutually acceptable nationally or regionally recognized public accounting firm, who shall be unaffiliated with and unrelated to either Landlord or Tenant or any of their officers, directors or employees, who shall be deemed to be acting as an expert and not arbitrator, and a written determination signed by the selected expert, and duly certified to both Landlord and Tenant, shall be final and binding on both Landlord and Tenant. Any adjustment required to any previous payment made by Tenant or Landlord by reason of any such decision shall be made within thirty (30) days thereof. In the event that the adjustment represents less than five percent (5%) of the Occupancy Costs that were the subject of the disagreement Tenant shall bear all costs of the expert making such determination. In the event that the adjustment represent an overstatement of five percent (5%) or more of the Occupancy Costs that were the subject of the disagreement Landlord shall bear all costs of the expert making such determination.

5.01.Use. The Premises shall be used and occupied only as business offices for the business of Tenant as conducted in the Premises and for reasonably related purposes, or for such other purpose as Landlord may specifically authorize in writing.

5.02.Compliance with Laws. The Premises shall be used and occupied in a safe, careful and proper manner so as not to contravene any present or future governmental or quasi-governmental laws in force or governmental regulations or orders applicable to Tenant’s use or occupancy of the Premises. If due solely to Tenant’s use or occupancy of the Premises, improvements are necessary to comply with any of the foregoing, Tenant shall pay the entire cost thereof. However, nothing herein shall require Tenant to comply with laws or requirements of public authorities which require the installation of new or additional, or the modification or replacement of existing, mechanical, electrical, plumbing or fire/life safety systems servicing or applied to the building systems as a whole (“Base Building”) without reference to the particular use of Tenant or any alterations performed by or for Tenant (“Building-Wide Laws”).

Tenant will have the right, at Tenant’s expense, to install suite identification signage including Tenant’s logo, on the walls of the elevator lobbies and on its entrance doors on those floors on which Tenant occupies the entire floor (the “Premises Identification Signage”). The appearance of the Premises Identification Signage and the means of attaching the Premises Identification Signage to the Building will be subject to Landlord’s prior written approval, which will not be unreasonably withheld, conditioned or delayed. Any other sign, lettering, decal or design of Tenant placed in or upon the Premises which is visible from the exterior of the Premises shall be at Tenant’s expense and subject to approval by Landlord (in Landlord’s sole discretion), shall conform to the uniform pattern of identification signs for tenants in the Building as prescribed by Landlord from time to time and shall be removed, and the surface it was located upon repaired and restored to the condition it was in prior to the installation of the same, by Tenant at its sole expense within five (5) business days after the expiration of the Term. Tenant shall not inscribe or affix any sign, lettering, decal or design in the Premises or Building which is visible from the exterior of the Building. Landlord, at its sole cost and expense, shall provide Tenant with Building Standard directory and suite signage.

In addition to Tenant’s pro rata share of Taxes, Tenant shall pay before delinquency every tax, assessment, license fee, excise and other charge, however described, which is imposed, levied, assessed or charged by any governmental or quasi-governmental authority having jurisdiction and which is payable in respect of the Term upon or on account of

(a)operations at, occupancy of, or conduct of business in or from the Premises but specifically excluding income, gross receipts or other taxes not directly related to Tenant’s occupancy of the Premises,

(b)fixtures or personal property in the Premises which do not belong to Landlord, and

(c)the Rent paid or payable by Tenant to Landlord for the Premises or for the use and occupancy of all or any part thereof, provided that if Landlord so elects by notice to Tenant, Tenant shall add any amounts payable under this Section 8.02 to the monthly installments of Annual Rent payable under Section 4.01 and Landlord shall remit such amounts to the appropriate authorities.

8.03.Right to Contest. Tenant shall have the right to contest in good faith the validity or amount of any tax, assessment, license fee, excise fee and other charge which it is responsible to pay under Section 8.02, and to withhold payment of the same during the pendency of such contest, provided that no contest by Tenant may involve the possibility of forfeiture, sale or disturbance of Landlord’s interest in the Premises, that Tenant provides to Landlord security for the taxes contested by Tenant adequate in the opinion of Landlord, and that, upon the final determination of any contest by Tenant, Tenant shall immediately pay and satisfy the amount found to be due, together with any costs, penalties and interest.

9.01.Landlord’s Insurance. During the Term, Landlord shall maintain at its own expense (subject to contribution by Tenant of its pro rata share of Occupancy Costs under Section 4.02) liability insurance, fire insurance with extended coverage, boiler and pressure vessel insurance, and other insurance on the Building and all property and interest of Landlord in the Building with property insurance coverage in amounts not less than eighty percent (80%) of the full replacement value of the Building (including coverage for rental loss in connection with damage and destruction) and with liability insurance in amounts of equal or greater coverage than amounts required of Tenant under Section 9.02 below Landlord’s policies for such insurance shall waive any

right of subrogation against Tenant and all individuals and entities for whom Tenant is responsible in law.

9.02.Tenant’s Insurance. During the Term, Tenant shall maintain at its own expense

(a)fire insurance with extended coverage and water damage insurance, in amounts sufficient to fully cover all leasehold improvements, fixtures and property in the Premises, and

(b)liability insurance, with blanket contractual liability coverage with Landlord and Landlord’s agent named as an additional insured, against claims for death, personal injury and property damage in or about the Premises, in amounts which are from time to time acceptable to a prudent tenant in the community in which the Building is located and satisfactory to Landlord but not less than $5,000,000 for death, illness or injury to one or more persons, and $2,000,000 for property damage, in respect of each occurrence.

Policies for such insurance shall be in a form and with an insurer reasonably acceptable to Landlord, shall require at least fifteen (15) days written notice to Landlord of termination or material alteration during the Term (provided, that if such notice terms are not commercially available in Colorado, in lieu of the foregoing, Tenant shall promptly notify Landlord of any termination or material alteration of any insurance policies of Tenant), and shall waive any right of subrogation against Landlord and all individuals and entities for whom Landlord is responsible in law and shall contain coverage for blanket contractual liability to cover indemnities included in this Lease. Tenant shall deliver to Landlord on the Commencement Date and on each anniversary thereof, evidence satisfactory to Landlord of such policies and that all premiums thereon have been paid and that the policies are in full force and effect.

10.01.Indemnity by Tenant. Subject to Section 10.03, and except to the extent caused by the gross negligence or willful misconduct or breach of this Lease by Landlord, or its employees, agents or contractors (except as it relates to (d) below), Tenant shall indemnify and hold harmless Landlord (and if Landlord requests, defend Landlord with counsel reasonably acceptable to Landlord) from and against liabilities, obligations, losses, damages, fines, penalties, demands, claims, causes of action, judgments, costs and expenses, including, without limitation, reasonable attorneys’ fees, which may be imposed on or incurred, suffered or paid by or asserted against Landlord or

the Building or any interest therein, arising from or by reason of or in connection with:

(e)any loss or damage resulting from Tenant’s grossly negligent or willful interference with or obstruction of deliveries to or from the Premises;

(f)any pollutant, toxic or hazardous material, substance or waste, or any other material which may adversely affect the environment, whether or not now recognized to have such to effect, which Tenant, its employees, agents, contractors or invitees bring upon, keep, use or locate in, on or about the Building, or any release or disposal of any such material, substance or waste in, on, about or from the Building by any of the foregoing; and

(g)any failure on the part of the Tenant to perform or comply with any of the covenants, agreements, terms, provisions, conditions or limitations contained in this Lease on its part to be performed or with which to be complied.

Nothing contained in this Section 10.01 shall be deemed to require Tenant to indemnify Landlord to any extent prohibited by law. Nothing contained in this Section 10.01 shall subject Tenant to any consequential or special damages.

10.02.Indemnity by Landlord.

Premises; or as a result of Landlord’s failure to maintain the Project in compliance with all Laws as required by Section 6.01 above. Nothing contained in this Lease shall be deemed to require Landlord to indemnify Tenant to any extent prohibited by law. Nothing contained in this Section 10.02 shall subject Landlord to any consequential or special damages.

10.03.Subrogation. The provisions of this Article 10.00 shall not abrogate or impair the waiver of any right of subrogation against Tenant in Landlord’s insurance under Section 9.01 and the waiver of any right of subrogation against Landlord in Tenant’s insurance under Section 9.02.

11.01.Assignment. Excluding any “Permitted Transfers” (as defined in Section 11.07 below), Tenant, if not then in default under this Lease beyond any applicable notice and cure period, and with Landlord’s prior written consent, may assign this Lease, subject to Sections 11.03 and 11.04, to any assignee who, in Landlord’s reasonable opinion, will not be inconsistent with the character of the Building and its other tenants, will use the Premises in a manner consistent with Article 5.00 thereof, has the financial capability of complying with the then remaining obligations of Tenant hereunder and who otherwise meets such other standards as Landlord may determine in its reasonable discretion.

11.02.Subleasing. Excluding any Permitted Transfers, Tenant, if not then in default under this Lease beyond any applicable notice and cure period, and with Landlord’s prior written consent and subject to Sections 11.03 and 11.04, may sublet all or any part of the Premises to a subtenant who, in Landlord’s reasonable opinion, will not be inconsistent with the character of the Building and its other tenants, will use the Premises in a manner consistent with Article 5.00 thereof, has the financial capability of complying with its obligations set forth in the sublease based on such subtenant’s financial obligations thereunder, and who otherwise meets such other standards as Landlord may determine in its reasonable discretion.

11.03.First Offer to Landlord. If Tenant wishes to sublet all of the Premises for the entire remaining Term of the Lease (except to a Permitted Transferee) to a named third party, Tenant shall first offer in writing to sublet to Landlord on the same terms and conditions as provided in this Lease except this Article 11.00, and for the same Rent as provided in this Lease or the rent offered to that third party if lower. If Tenant wishes to assign this Lease (except to a Permitted Transferee), Tenant shall first offer to Landlord in writing to surrender this Lease on the effective date of the proposed assignment by Tenant. Landlord will have ten (10) business days from the receipt of Tenant’s

offer to sublease or assign either to accept or reject it. If Landlord accepts the offer, Tenant will then execute and deliver to Landlord, or to any party designated or named by Landlord, an assignment or sublease, as the case may be, in either case in form and substance reasonably satisfactory to Landlord.

11.04.Limitation. Except as specifically provided in this Article 11.00, Tenant shall not assign or transfer this Lease or any interest therein or sublet or in any way part with possession of all or any part of the Premises, or permit all or any part of the Premises to be used or occupied by any other person. Any assignment, transfer or subletting or purported assignment, transfer or subletting except as specifically provided herein shall be null and void and of no force and effect without limiting Landlord’s right to approve or disapprove any assignment or sublease pursuant to Sections 11.01 and 11.02 hereof. Landlord shall not be required to consent to an assignment of this Lease or a sublease of all or part of the Premises by Tenant to, or the use or occupancy of all or part of the Premises by any tenant in the Building, or any tenant to whom Landlord or an affiliate of Landlord has then made an outstanding offer to lease space in the Building within the prior six (6) months. The rights and interests of Tenant under this Lease shall not be assignable by operation of law without Landlord’s written consent, which consent may be withheld in Landlord’s absolute discretion. Except with respect to an assignment or sublease to a Permitted Transferee, Tenant shall pay to Landlord immediately upon receipt by Tenant from time to time fifty percent (50%) of (a) all revenue from any approved assignment, or (b) all revenue from any approved sublease which exceeds the sum of all Annual Rent and Occupancy Costs payable by Tenant to Landlord under this Lease in respect of the Premises being subleased for the period of time to which such revenue under such sublease relates less, in the case of (a) or (b) above all actual, reasonable and customary out-of-pocket costs and expenses incurred by Tenant in connection with such subleasing, or assignment, including, without limitation, free rent, brokerage commissions and improvement allowances, but expressly excluding attorneys’ fees. All such amounts shall constitute Rent and be subject to all terms and provisions of this Lease, including, without limitation, Article 19.00 hereof. Upon Landlord’s approval of any assignment, or sublease, Tenant shall pay to Landlord a reasonable charge to cover Landlord’s administrative costs in connection with that approval, not to exceed Two Thousand Five Hundred Dollars ($2,500.00) in each instance.

11.05.Tenant’s Obligations Continue. No assignment, transfer or subletting (or use or occupation of the Premises by any other person) which is permitted under this Article 11.00 shall in any way release or relieve Tenant of its

obligations under this Lease, unless otherwise agreed upon by Landlord in writing in Landlord’s sole discretion.

11.06.Subsequent Assignments. Landlord’s consent to an assignment, transfer or subletting (or use or occupation of the Premises by any other person) shall not be deemed to be a consent to any subsequent assignment, transfer, subletting, use or occupation, all of which shall be permitted only in accordance with the provisions of this Article 11.00.

11.07.Permitted Transfers. Notwithstanding anything contained in this Article 11.00 to the contrary, Tenant may assign or sublet all or part of its interest in this Lease or all or part of the Premises (a “Permitted Transfer”) to the following types of entities (a “Permitted Transferee”) without the consent of Landlord: (i) any person or entity which, directly or indirectly, through one or more intermediaries, controls, is controlled by, or is under common control with Tenant; (ii) any corporation, limited partnership, limited liability partnership, limited liability company or other business entity in which or with which Tenant, or its corporate successors or assigns, is merged or consolidated; or (iii) any corporation, limited partnership, limited liability partnership, limited liability company or other business entity acquiring all or substantially all of the stock or other equity interests of Tenant or all or substantially all of the assets of Tenant (expressly excluding transfers through bankruptcy or other insolvency liquidation of Tenant’s assets). Tenant shall promptly notify Landlord of any such Permitted Transfer. The Permitted Transferee shall comply with all of the terms and conditions of this Lease.

11.08.Building Directory Changes. The listing or posting of any name, other than that of Tenant, whether on the door or exterior wall of the Premises, the Building’s tenant directory in the lobby or elevator, or elsewhere, shall not:

(a)constitute a waiver of Landlord’s right to withhold consent to any sublet or assignment pursuant to this Article 11.00;

(b)be deemed an implied consent by Landlord to any sublet of the Premises or any portion thereof, to any assignment or transfer of the Lease, or to any unauthorized occupancy of the Premises, except in accordance with the express terms of the Lease; or

(c)operate to vest any right or interest in the Lease or in the Premises.

12.01.Possession. Upon the expiration or other termination of the Term, all right, title and interest of Tenant in the Premises shall cease. Upon such expiration or other termination, Tenant shall immediately quit and surrender possession

of the Premises in substantially the condition in which Tenant is required to maintain the Premises excepting only reasonable wear and tear, from condemnation, Landlord’s maintenance and repair obligations, or casualty, provided Tenant pays or assigns to Landlord all insurance proceeds applicable to Tenant’s leasehold improvements in the Premises in the amounts required to be maintained by Tenant under Section 9.02(a) above. Tenant shall not be obligated to remove any of the initial Improvements to the Premises or any Minor Alterations to the Premises other than any internal staircase created by or on behalf of Tenant, including repairing floor openings to slab condition, the removal of all telecommunication equipment where ever located (subject to Section 21.03 below), and/or the removal of the back-up generator described in Section 28.27 below, all within five (5) business days after the expiration of the Lease, and repair any damage caused by such removal whether or not the removal is at Landlord’s request, all in accordance with the provisions of Article 7.00.

12.02.Trade Fixtures, Personal Property and Improvements. After the expiration or other termination of the Term, all of Tenant’s trade fixtures, personal property and improvements remaining in the Premises shall be deemed conclusively to have been abandoned by Tenant and may be appropriated, sold, destroyed or otherwise disposed of by Landlord without notice or obligation to compensate Tenant or to account therefore, and Tenant shall pay to Landlord on written demand all reasonable, out-of-pocket costs incurred by Landlord in connection therewith.

12.03.Merger. The voluntary or other surrender of this Lease by Tenant or the cancellation of this Lease by mutual agreement of Tenant and Landlord shall not work a merger, and shall at Landlord’s option terminate all or any subleases and subtenancies or operate as an assignment to Landlord of all or any subleases or subtenancies. Landlord’s option hereunder shall be exercised by notice to Tenant and all known sublessees or subtenants in the Premises or any part thereof.

12.04.Payments After Termination or Notice. No payments of money by Tenant to Landlord after the expiration or other termination of the Term or after the giving of any notice (other than a demand for payment of money) by Landlord to Tenant, shall reinstate, continue or extend the Term or make ineffective any notice given to Tenant prior to the payment of such money. After the service of notice or the commencement of a suit, or after final judgment granting Landlord possession of the Premises, Landlord may receive and collect any sums of Rent due under this Lease, and the payment thereof shall not make ineffective any notice, or in any manner affect any pending suit or any judgment theretofore obtained.

13.01.Month-to-Month Tenancy. If with Landlord’s prior written consent, which may be withheld in Landlord’s sole discretion, Tenant remains in possession of the Premises after the expiration or other termination of the Term, Tenant shall be deemed to be occupying the Premises on a month-to-month tenancy only, at a monthly rental equal to 150% of the last monthly installment of Annual Rent and Occupancy Costs of the Term as determined in accordance with Article 4.00, and such month-to-month tenancy may be terminated by Landlord or Tenant on the last day of any calendar month by delivery of at least 30 days advance notice of termination to the other.

13.02.Tenancy at Sufferance. If without Landlord’s written consent, which may be withheld in Landlord’s sole discretion, Tenant remains in possession of the Premises after the expiration or other termination of the Term, Tenant shall have committed an unlawful detention of the Premises and Landlord shall be entitled to all rights and remedies available at law or equity as a result thereof; provided, however, that if at any time after the expiration or termination of the Term, Landlord so notifies the Tenant in writing, Tenant shall be deemed to be occupying the Premises upon a tenancy at sufferance only, at a monthly rental equal to two (2) times the Annual Rent and Occupancy Costs for the last month of the Term determined in accordance with Article 4.00. Such tenancy at sufferance may be terminated by Landlord at any time by notice of termination to Tenant, and by Tenant on the last day of any calendar month by at least 30 days advance notice of termination to Landlord. Notwithstanding the foregoing, Landlord shall also be entitled to such other remedies and damages provided under this Lease or at law as a result of such tenancy at sufferance.

13.03.General. Any month-to-month tenancy or tenancy at sufferance hereunder shall be subject to all other terms and conditions of this Lease except any right of extension and nothing contained in this Article 13.00 shall be construed to limit or impair any of Landlord’s rights of re-entry or eviction or constitute a waiver thereof.

14.01.Purpose. The Rules and Regulations in Exhibit C have been adopted by Landlord for the safety, benefit and convenience of all tenants and other persons in the Building.

14.02.Observance. Tenant shall at all times comply with, and shall cause its employees, agents, licensees and invitees to comply with, the Rules and

Regulations from time to time in effect to the extent the same do not conflict with the terms and conditions of this Lease.

14.03.Modification. Landlord may from time to time, for the purposes set out in Section 14.01, amend, delete from, or add to the Rules and Regulations, provided that any such modification

(a)shall not be inconsistent with any other provision of this Lease,

(b)shall be reasonable and have general application to all similarly situated tenants in the Building,

(c)shall be effective only upon delivery of a copy thereof to Tenant at the Premises; and

(d)shall not increase Tenant’s financial obligations or materially alter its rights under this Lease.

14.04.Non-Compliance. Landlord shall use reasonable efforts to secure compliance by all tenants and other persons with the Rules and Regulations from time to time in effect, but shall not be responsible to Tenant for failure of any person to comply with such Rules and Regulations nor shall any such failure relieve Tenant of its obligation to comply with the Rules and Regulations.

(a)if in the reasonable opinion of Landlord, substantial alteration or reconstruction of the Building is necessary or desirable as a result thereof, whether or not the Premises are or may be affected, Landlord shall have the right to terminate this Lease by giving Tenant at least 30 days written notice of such termination, which notice shall be given within 30 days after the Date of Such Taking, and

(b)if in the reasonable opinion of Tenant such taking will prevent Tenant from conducting its business in the Premises in a manner reasonably comparable to that conducted immediately before such taking for a period of more than one hundred eighty (180) days, Tenant shall have

the right to terminate this Lease by giving at least 30 days written notice thereof, which notice shall be given within 30 days after the Date of Such Taking.

If either party exercises its right of termination hereunder, this Lease shall terminate on the date stated in the notice, provided, however, that no termination pursuant to notice hereunder may occur later than 60 days after the Date of Such Taking.

15.03.Surrender. On any such date of taking under Sections 15.01 or 15.02, Tenant shall immediately surrender to Landlord the Premises and all interests therein under this Lease. Landlord may re-enter and take possession of the Premises and remove Tenant therefrom, and the Rent shall no longer accrue from the Date of Such Taking, except that if a portion of the Premises is included as a part of such taking, then that portion of the Rent attributable to such portion, determined by Landlord pro rata based on the number of rentable square feet contained within such portion, shall no longer accrue from the Date of Such Taking. After such termination, and on notice from Landlord stating the Rent then owing, Tenant shall forthwith pay Landlord such Rent.

15.04.Partial Taking of Premises. If any portion of the Premises (but less than the whole thereof) is so taken, and no rights of termination herein conferred are timely exercised, the Term of this Lease shall expire with respect to the portion so taken on the Date of Such Taking. In such event, the Rent payable hereunder with respect to such portion so taken shall no longer accrue from such date, and the Annual Rent and Occupancy Costs thereafter payable with respect to the remainder not so taken shall be adjusted pro rata by Landlord in order to account for the resulting reduction in the number of square feet in the Premises.

15.05.Awards. Upon any such taking or purchase, Landlord shall be entitled to receive and retain the entire award or consideration for the affected lands and improvements subject to the rights of any mortgagee of Landlord’s interest in the Land or the Building as their respective interests may appear, and Tenant shall not have or advance any claim against Landlord or the condemning authority for the value of its property or its leasehold estate or the unexpired Term of this Lease, or, except as otherwise permitted in the next sentence, for costs of removal or relocation, or business interruption expense or any other damages arising out of such taking or purchase. Nothing herein shall give Landlord any interest in or preclude Tenant from seeking and recovering on its own account from the condemning authority any award or compensation attributable to the taking or purchase of Tenant’s chattels or trade fixtures or attributable to Tenant’s relocation expenses or loss of business, provided that

any such separate claim by Tenant shall not reduce or adversely affect the amount of Landlord’s award. If any such award made or compensation paid to either party specifically includes an award or amount for the other, the party first receiving the same shall promptly account therefore to the other.

16.01.Limited Damage to Premises. If all or part of the Premises are rendered untenantable by damage affecting the Building or the Premises from fire or other casualty which in Landlord’s reasonable opinion can be substantially repaired under applicable laws and governmental regulations within two hundred and ten (210) days from the later to occur of (a) the date of such casualty (employing normal construction methods without overtime or other premium); or (b) the date on which Landlord receives the insurance proceeds relating to such casualty, Landlord shall, but only to the extent that sufficient insurance proceeds are available therefore, (and subject to the rights of any mortgagee of the Land or the Building in and to such insurance proceeds), repair such damage, including damage to the leasehold improvements in the Premises; provided that Landlord will not be required to repair any damage to such leasehold improvements in excess of the amount covered by proceeds from Tenant’s insurance policy covering such improvements. Landlord will have no obligation to repair or restore any other property of Tenant (such as Tenant’s furniture or trade fixtures), and Tenant, at its expense, will repair or restore such property to the extent Tenant elects.

16.02.Major Damage to Premises. If all or part of the Premises are rendered untenantable by damage from fire or other casualty affecting the Building or the Premises, which in Landlord’s reasonable opinion, as set forth in a written notice given to Tenant, cannot be substantially repaired under applicable laws and governmental regulations within two hundred and forty (240) days from the date of such casualty (employing normal construction methods without overtime or other premium), then either Landlord or Tenant may elect to terminate this Lease as of the date of such casualty by written notice delivered to the other not more than thirty (30) days after Landlord gives Tenant such written notice, failing which Landlord shall (subject to the rights of any mortgagee of the Land or the Building in and to such insurance proceeds), repair such damage other than damage to improvements, furniture, chattels or trade fixtures which do not belong to Landlord, which shall be repaired forthwith by Tenant at its own expense.

16.03.Abatement. If Landlord elects to repair damage to all or part of the Premises under Sections 16.01 or 16.02, or the Building under Section 16.04 below (provided Tenant is not continuing to conduct business from the Premises or the applicable portion thereof) the Annual Rent and Occupancy Costs payable

by Tenant hereunder shall be proportionately reduced based on the number of square feet within the Premises which are thereby rendered untenantable from the date of such casualty until five (5) days after completion by Landlord of the repairs to the Premises (or the part thereof rendered untenantable) or until Tenant again uses the Premises (or the part thereof rendered untenantable) in its business, whichever first occurs.

16.04.Major Damage to Building. If all or a substantial part (whether or not including the Premises) of the Building is rendered untenantable by damage from fire or other casualty to such a material extent that Landlord determines not to repair the same, Landlord may elect to terminate this Lease as of the date of such casualty (or on the date of notice if the Premises are unaffected by such casualty) by written notice delivered to Tenant not more than 60 days after the date of such casualty. If Landlord elects not to terminate this Lease, Landlord shall, but only to the extent that sufficient insurance proceeds are available therefore (and subject to the rights of any mortgagee of the Land or the Building in and to such insurance proceeds), commence repair of the damaged portion of the Building, and the Lease shall remain in full force and effect in accordance with its terms, subject to Section 16.03 above.

16.05.Limitation on Landlord’s Liability. Except as specifically provided in this Article 16.00, there shall be no reduction of Rent and Landlord shall have no liability to Tenant by reason of any injury to or interference with Tenant’s business or property arising from fire or other casualty, howsoever caused, or from the making of any repairs resulting therefrom in or to any portion of the Building or the Premises.

16.06.Completion of Restoration. If Landlord is obligated to, or elects to, repair and restore the Premises and/or Building, as provided in Section 16.01 or 16.02 above, and Landlord fails to complete such restoration within the time periods provided therein, then Tenant shall have the right to terminate this Lease upon written notice delivered to Landlord at any time after the expiration of such time periods, and provided that Landlord fails to deliver the Premises in the manner required therein within thirty (30) days of receipt of Tenant’s notice of termination, then this Lease shall terminate without any further notice or action on either party’s part.

17.01.Sale, Conveyance and Assignment. Nothing in this Lease shall restrict the right of Landlord to sell, convey, assign or otherwise deal with the Building, subject only to the rights of Tenant under this Lease.

17.02.Effect of Sale, Conveyance, or Assignment. A sale, conveyance or assignment of the Building shall operate to release Landlord from liability from and after the effective date thereof upon all of the covenants, terms and conditions of this Lease, express or implied, except as such may relate to the period prior to such effective date, or a condition in existence prior to such effective date, and effective as of such effective date, Tenant shall look solely to Landlord’s successor in interest in and to this Lease with respect to liability originating on and after such effective date. This Lease shall not be affected by any such sale, conveyance or assignment, and Tenant shall immediately and automatically attorn to Landlord’s successor in interest thereunder. Such attornment shall be effective and self-operative upon Landlord’s sale, conveyance or assignment of the Building, without the execution of any further instruments or the undertaking of any further acts.

17.03.Subordination. This Lease is and shall be subject and subordinate in all respects to all mortgages or deeds of trust and assignments of leases and rents now or hereafter encumbering the Building or Land and to all extensions, amendments, modifications, supplements, consolidations, extensions, revisions and replacements thereof and to all advances made or hereafter made upon the security thereof. However, a holder of any mortgage or deed of trust may elect to subordinate, in whole or in part, by an instrument in form and substance satisfactory to the holder, the mortgage or deed of trust to this Lease. Notwithstanding the foregoing, Landlord will use commercially reasonable efforts to obtain from the Building’s current lender the Subordination, Non-Disturbance and Attornment Agreement attached hereto as Exhibit E, subject to reasonable revisions requested by Tenant and acceptable to such lender; and, as a condition to Tenant’s subordination being effective, will obtain from any future lender a subordination, non-disturbance and attornment agreement on the lender’s then standard form, subject to reasonable revisions requested by Tenant and acceptable to such lender, which will provide in substance that so long as Tenant is not in default under the Lease beyond any applicable notice and cure period, Tenant’s use and occupancy of the Premises shall not be disturbed, notwithstanding any default of Landlord under any mortgage, deed of trust or other security agreement held by such lender.

17.04.Attornment. Subject to Section 17.05, if the Building is transferred to any person or entity (herein called “Purchaser”) by reason of foreclosure or other proceedings for enforcement of a mortgage or deed of trust, or by delivery of a deed in lieu of such foreclosure or other proceedings, or if the rights under any assignment of leases and rents are exercised by the holder thereof, Tenant shall immediately and automatically attorn to Purchaser or the holder of the assignment of leases and rents, as the case may be.

17.05.Non-disturbance. No attornment under Section 17.04 shall be effective unless (and until):

(a)the holder of the mortgage or deed of trust has subordinated, in whole or in part, the mortgage or deed of trust to this Lease, or

(b)Purchaser delivers to Tenant a written undertaking, in a form as provided in Section 17.03 above, binding upon Purchaser and enforceable by and for the benefit of Tenant under applicable law, that this Lease and Tenant’s rights hereunder shall continue undisturbed while Tenant is not in default, beyond any applicable notice and cure period, despite such enforcement proceedings and transfer.

17.06.Effect of Attornment. Upon attornment under Section 17.04, this Lease shall continue in full force and effect as a direct lease between Purchaser (or the holder of the assignment of leases and rents if applicable) and Tenant, upon all of the same terms, conditions and covenants as are set forth in this Lease except that, after such attornment, Purchaser (or the holder of the assignment of leases and rents if applicable) shall not be

(a)subject to any offsets or defenses which Tenant might have against Landlord, except to the extent any condition giving rise to such offsets or defenses continues for a period of thirty (30) days after such attornment and receipt of written notice from Tenant of such offsets and defenses , or

(b)bound by any prepayment by Tenant of more than one month’s installment of Rent, unless such prepayment shall have been approved in writing by, in the case of a transfer in connection with a foreclosure, deed in lieu of foreclosure or other proceedings relating to any such mortgage or deed of trust, the mortgagee of Landlord’s interest in the Land or Building, by Purchaser or by any predecessor in interest of Purchaser, except Landlord; or, in the case of the exercise of the rights under any assignment of leases and rents, by the holder of such assignment of leases and rents, or by any predecessor in interest of such holder, or

(c)subject to the obligations hereunder except during the period of Purchaser’s ownership of the Building or Land, or

(d)liable for any previous act or omission by Landlord under this Lease, or

(e)obligated with respect to any security deposit under this Lease unless such security deposit has been delivered to Purchaser or holder of any assignment of leases and rents, as the case may be (provided, that in

no event shall Tenant be requirement to submit any additional or replacement security deposit to Purchaser), or

(f)bound or liable under any provisions in this Lease whereby Landlord assumed the obligations of Tenant covering space in other buildings.

17.07.Execution of Instruments. The subordination and attornment provisions of this Article 17.00 shall be self-operating and (except as specifically required in Section 17.03) no further instrument shall be necessary. Nevertheless Tenant, on request by and without cost to Landlord or any successor in interest, shall execute and deliver any and all commercially reasonable instruments further evidencing such subordination and (where applicable hereunder) attornment to the extent consistent with this Article 17.00.

18.01.Notices. All notices, demands, billings, consents or other instruments or communications provided for under this Lease shall be in writing, signed by the party giving the same, and shall be deemed properly given and received (a) when actually hand delivered and received or (b) three business days after placement in the United States mail, if sent by registered or certified mail, postage prepaid, or (c) the business day following delivery to an overnight courier service, if such courier service obtains a written acknowledgement of receipt, addressed, if to Tenant, at the Premises (whether or not Tenant has departed from, vacated or abandoned the same) and, if to Landlord, at the address set forth in the first paragraph of this Lease, with a copy to:

or, at such other address as either party may notify the other of in writing in the manner provided in this Section 18.01.

18.02.Acknowledgements. Tenant shall at any time and from time to time, within ten (10) days after Landlord’s written request, execute, acknowledge and deliver a written statement, with the form and substance of such notice and the party or parties to whom it is addressed to be determined by Landlord, ratifying this Lease and, except as otherwise noted by Tenant in the statement, certifying as to the truth or untruth of such reasonable matters as

are set forth in such statement. Any such statement may be relied upon by any prospective transferee or encumbrancer of all or any portion of the Building or any assignee of any such persons. If Tenant fails to timely deliver such statement, Tenant shall be deemed to have acknowledged that this Lease is in full force and effect, without modification except as may be represented by Landlord, and that there are no uncured defaults in Landlord’s performance. Landlord agrees periodically to furnish, upon not less than ten (10) days prior written request by Tenant, certificates signed by Landlord containing information similar to the foregoing information

18.03.Authorities for Action. Landlord may act in any matter provided for herein by its property manager, or any of its officers or general partners and any other person who shall from time to time be designated by Landlord by notice to Tenant. Tenant shall designate in writing one or more persons to act on its behalf in any matter provided for herein and may from time to time change, by notice to Landlord, such designation. In the absence of any such designation, the person or persons executing this Lease for Tenant shall be deemed to be authorized to act on behalf of Tenant in any matter provided for herein.

19.01.Interest and Costs. Tenant shall pay monthly to Landlord interest at a rate equal to the lesser of 1.5% per month or the maximum rate permitted by applicable law, on all Rent required to be paid hereunder from five (5) days after the due date for payment thereof until the same is fully paid and satisfied. Tenant shall indemnify Landlord against all costs and charges (including legal fees) lawfully and reasonably incurred in enforcing payment thereof, and in obtaining possession of the Premises after default of Tenant beyond any applicable notice and cure period, or upon expiration or earlier termination of the Term of this Lease, or in enforcing any covenant, proviso or agreement of Tenant herein contained.

19.02.Events of Default. Each of the following events will constitute a material breach by Tenant and an “Event of Default” under this Lease:

(a)Failure to Pay Rent. Tenant fails to pay Annual Rent, Occupancy Costs or any Other Charges payable by Tenant under the terms of this Lease when due, and such failure continues for five (5) business days after written notice from Landlord to Tenant of such failure; provided that with respect to Annual Rent and Occupancy Costs, Tenant will be entitled to only two notices of such failure during any calendar year and if, after two (2) such notices are given in any calendar year, Tenant fails, during such calendar year, to pay any such amounts when due, such failure

will constitute an Event of Default without further notice by Landlord or additional cure period.

(b)Failure to Perform Other Obligations. Tenant breaches or fails to comply with any other provision of this Lease applicable to Tenant, and such breach or noncompliance continues for a period of ten (10) business days after written notice by Landlord to Tenant; or, if such breach or noncompliance cannot be reasonably cured within such 10 business day period, Tenant does not in good faith commence to cure such breach or noncompliance within such 10 business day period, or does not diligently complete such cure within forty-five (45) days after such notice from Landlord. However, if such breach or noncompliance causes or results in (i) a dangerous condition on the Premises or Building, (ii) any insurance coverage carried by Landlord or Tenant with respect to the Premises or Building being jeopardized, or (iii) a material disturbance to another tenant, then an Event of Default will exist if such breach or noncompliance is not cured as soon as reasonably possible after notice by Landlord to Tenant, and in any event is not cured within twenty (20) days after such notice. For purposes of this subsection 19.02(b), financial inability will not be deemed a reasonable ground for failure to immediately cure any breach of, or failure to comply with, the provisions of this Lease.

(c)Transfer of Interest Without Consent. Tenant’s interest under this Lease or in the Premises is transferred or passes to, or devolves upon, any other party in violation of Article 11.00.

(d)Execution and Attachment Against Tenant. Tenant’s interest under this Lease or in the Premises is taken upon execution or by other process of law directed against Tenant, or is subject to any attachment by any creditor or claimant against Tenant and such attachment is not discharged or disposed of within ten (10) days after levy.

(e)Bankruptcy or Related Proceedings. Tenant files a petition in bankruptcy or insolvency, or for reorganization or arrangement under any bankruptcy or insolvency laws, or voluntarily takes advantage of any such laws by answer or otherwise, or dissolves or makes an assignment for the benefit of creditors, or involuntary proceedings under any such laws or for the dissolution of Tenant are instituted against Tenant, or a receiver or trustee is appointed for the Premises or for all or substantially all of Tenant’s property, and such proceedings are not dismissed or such receivership or trusteeship vacated within sixty (60) days after such institution or appointment.

19.03.Landlord’s Remedies. Time is of the essence. If any Event of Default occurs, Landlord will have the right, at Landlord’s election, then or at any later time, to exercise any one or more of the remedies described below. Exercise of any of such remedies will not prevent the concurrent or subsequent exercise for any other remedy provided for in this Lease or otherwise available to Landlord at law or in equity.

(a)Cure by Landlord. 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 deems necessary or desirable to cure any Event of Default in such manner and to such extent as Landlord deems necessary or desirable. Landlord may do so without additional demand on, or additional written notice to Tenant and without giving Tenant an additional opportunity to cure such an Event of Default. Tenant covenants and agrees to pay Landlord, upon demand, all advances, costs and expenses of Landlord in connection with making any such payment or taking any such action, including reasonable attorney’s fees, together with interest at the rate described in Section 19.01 from the date of payment of any such advances, costs and expenses by Landlord.

(b)Termination of Lease and Damages. 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 Premises from Tenant. Tenant will remain liable to Landlord for damages in an amount equal to the Annual Rent, Occupancy Costs and Other Charges which would have been owing by Tenant for the balance of the Term had this Lease not been terminated, less the net proceeds, if any, of any reletting of the Premises by Landlord subsequent to such termination, after deducting all Landlord’s expenses in connection with such recovery of possession or reletting. Landlord will be entitled to collect and receive such damages from Tenant on the days on which the Annual Rent, Occupancy Costs and Other Charges would have been payable if this Lease had not been terminated. Alternatively, at Landlord’s option, Landlord will be entitled to recover from Tenant, as damages for loss of the bargain and not as a penalty, an aggregate sum equal to (i) all unpaid Annual Rent, Occupancy Costs and Other Charges for any period prior to the termination date of this Lease (including interest from the due date to the date of the award at the rate described in Section 19.01), plus any other sum of money and damages owed by Tenant to Landlord for events or actions occurring prior to the termination date; plus (ii) the present value at the time of termination (calculated at the Prime Rate of

the Wells Fargo Denver, N.A. or its successor on the termination date) of the amount, if any, by which (A) the aggregate of the Annual Rent, Occupancy Costs, and all Other Charges payable by Tenant under this Lease that would have accrued for the balance the Term after termination (with respect to Occupancy Costs, such aggregate will be calculated by assuming that Occupancy Costs for the Fiscal Year in which termination occurs and for each subsequent Fiscal Year remaining in the Term of this Lease had not been terminated will increase by 8% per year over the amount of Occupancy Costs for the prior Fiscal Year), exceeds (B) the amount of such Annual Rent, Occupancy Costs and Other Charges which Landlord will receive for the remainder of the Term from any reletting of the Premises occurring prior to the date of the award, or if the Premises have not been re let prior to the date of the award the amount, if any, of such Annual Rent, Occupancy Costs and Other Charges which could reasonably be recovered by reletting the Premises for the remainder of the Term at the then-current fair rental value, in either case taking into consideration loss of Rent while finding a new tenant, tenant improvements and rent abatements necessary to secure a new tenant, leasing brokers’ commissions and other costs which Landlord has incurred or might incur in leasing the Premises to new tenant; plus (iii) interest on the amount described in (ii) above from the termination date to the date of the award at the rate described in Section 19.01.

(c)Repossession and Reletting. Landlord may reenter and take possession of all or any part of the Premises, without additional demand or notice, and repossess the same and expel Tenant and any party claiming by, through or under Tenant, and remove the effects of both using such force for such purposes as may be necessary, without being liable for prosecution for such action 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 Premises by Landlord will 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 or notice given under a forcible entry and detainer statute or similar laws will 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 the Lease will terminate as specified in such notice. After recovering possession of the Premises, Landlord may, from time to time, but will not be obligated to, relet all or any part of the Premises for

Tenant’s account, for such term or terms and on such conditions and other terms as Landlord, in its discretion, determines. Landlord may make such repairs, alterations or improvements as Landlord considers appropriate to accomplish such reletting, and Tenant will reimburse Landlord upon demand for all costs and expenses, including attorneys’ fees, which Landlord may incur in connection with such reletting. Landlord may collect and receive the rents for such reletting but Landlord will in no way be responsible or liable for any failure to relet the Premises or for any inability to collect any rent due upon such reletting. Regardless of Landlord’s recovery of possession of the Premises, Tenant will continue to pay on the dates specified in this Lease, the Annual Rent, Occupancy Costs, and Other Charges which would be payable if such repossession had not occurred, less a credit for the net amounts, if any, actually received by Landlord through any reletting of the Premises. Alternatively, at Landlord’s option, Landlord will be entitled to recover from Tenant, as damages for loss of the bargain and not as a penalty, an aggregate sum equal to (i) all unpaid Annual Rent, Occupancy Costs and Other Charges for any period prior to the repossession date (including interest from the due date to the date of the award at the rate described in Section 19.01), plus any other sum of money and damages owed by Tenant to Landlord for events or actions occurring prior to the repossession date; plus (ii) the present value at the time of repossession (calculated at the Prime Rate of the Wells Fargo Denver, N. A. or its successor on the repossession date) of the amount, if any, by which (A) the aggregate of the Annual Rent, Occupancy Costs and all Other Charges payable by Tenant under this Lease that would have accrued for the balance of the Term after repossession (with respect to Occupancy Costs, such aggregate will be calculated by assuming that Occupancy Costs for the Fiscal Year in which repossession occurs and for each subsequent Fiscal Year remaining in the Term if Landlord had not repossessed the Premises will increase by 8% per year over the amount of Occupancy Costs for the prior Fiscal Year), exceeds (B) the amount of such Annual Rent, Occupancy Costs and Other Charges which Landlord will receive for the remainder of the Term from any reletting of the Premises occurring prior to the date of the award, the amount, if any, of such Annual Rent, Occupancy Costs and Other Charges which could reasonably be recovered by reletting the Premises for the remainder of the Term at the then-current fair rental value, in either case taking into consideration loss of Rent while finding a new tenant, tenant improvements and rent abatements necessary to secure a new tenant, leasing brokers’ commissions and other costs which Landlord has incurred or might incur in leasing the Premises to a new tenant; plus (iii)

interest on the amount described in (ii) above from the repossession date to the date of the award at the rate described in Section 19.01.

(d)Bankruptcy Relief. Nothing contained in this Lease will limit or prejudice Landlord’s right 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 laws 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.

(e)Mitigation of Damages. Following any termination of Tenant’s right to possession only, without termination of the Lease, Landlord agrees to use reasonable efforts to relet the Premises at fair market rental rates and to otherwise mitigate any damages arising out of an Event of Default on the part of Tenant; provided, however, that (i) Landlord shall have no obligation to treat preferentially the Premises compared to other premises or vacant space Landlord has available for leasing within the Building; (ii) Landlord shall not be obligated to expend any efforts or any monies to relet the Premises beyond those Landlord would expend in the ordinary course of leasing space within the Building; (iii) Landlord shall not be obligated to re-lease the Premises for a rental less than the then prevailing current fair market rent for comparable office space in comparable Class A, multi-tenant high rise office towers in the Central Business District; and (iv) in evaluating a prospective reletting of the Premises, the term, rental, use and the reputation, experience and financial standing of prospective tenants are factors which Landlord may properly consider in its reasonable discretion.

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

20.01.Bankruptcy.

(a)In the event a petition is filed by or against Tenant under the Bankruptcy Code, Tenant, as debtor and debtor in possession, and any trustee who may be appointed, agree to adequately protect Landlord as follows:

(i)to pay monthly in advance on the first day of each month as reasonable compensation for use and occupancy of the Premises an amount equal to all Rent due pursuant to this Lease; and

(ii)to perform each and every obligation of Tenant under this Lease until such time as this Lease is either rejected or assumed by order of a court of competent jurisdiction; and

(iii)to determine within 60 days after the filing of such petition whether to assume or reject this lease; and

(iv)to give Landlord at least 30 days prior written notice, unless a shorter notice period is agreed to in writing by the parties, of any proceeding relating to any assumption of this Lease; and

(v)to give at least 30 days prior written notice of any vacation or abandonment (including any vacation or abandonment specifically described in Section 5.03) of the Premises, any such vacation or abandonment to be deemed a rejection of this Lease; and

(vi)to do all other things of benefit to Landlord otherwise required under the Bankruptcy Code.

Tenant shall be deemed to have rejected this Lease in the event of the failure to comply with any of the above.

(b)If Tenant or a trustee elects to assume this Lease subsequent to the filing of a petition under the Bankruptcy Code, Tenant, as debtor and as debtor in possession, and any trustee who may be appointed agree as follows:

(i)to cure each and every existing breach by Tenant within not more than 90 days of assumption of this Lease; and

(ii)to compensate Landlord for any actual pecuniary loss resulting from any existing breach, including without limitation, Landlord’s reasonable costs, expenses and attorney’s fees incurred as a result of the breach, as determined by a court of competent jurisdiction, within 90 days of assumption of this Lease; and

(iii)in the event of an existing breach, to provide adequate assurance of Tenant’s future performance, including without limitation:

(A)the deposit of an additional sum equal to three months’ Rent to be held (without any allowance for interest thereon) to secure Tenant’s obligations under the Lease; and

(B)the production to Landlord of written documentation establishing that Tenant has sufficient present and anticipated financial ability to perform each and every obligation of Tenant under this Lease; and

(C)assurances, in a form acceptable to Landlord, as may be required under any applicable provision of the Bankruptcy Code; and

(iv)the assumption will not breach any provision of this Lease; and

(v)the assumption will be subject to all of the provisions of this Lease unless the prior written consent of Landlord is obtained; and

(vi)the prior written consent to the assumption of any mortgagee or ground lessor to which this Lease has been assigned as collateral security is obtained.

(c)If Tenant assumes this Lease and proposes to assign the same pursuant to the provisions of the Bankruptcy Code to any person or entity who shall have made a bona fide offer to accept any assignment of this lease on terms acceptable to Tenant, then notice of such proposed assignment, setting forth:

(i)the name and address of such person,

(ii)all the terms and conditions of such offer, and

(iii)the adequate assurance to be provided Landlord to assure such person’s future performance under the Lease, including without limitation, the assurances referred to in any applicable provision of the Bankruptcy Code, shall be given to Landlord by Tenant no later than twenty (20) days after receipt by Tenant, but in any event no later than ten (10) days prior to the date that Tenant shall make application to a court of competent jurisdiction for authority and approval to enter into such assignment and assumption, and Landlord shall thereupon have the prior right and option, to be exercised by notice to Tenant given at any time prior to the effective date of such proposed assignment, to accept an assignment of this Lease upon the same terms and conditions and for the same consideration, if any, as the bona fide offer made by such person, less any brokerage commissions which may be payable out of the consideration to be paid by such person for the assignment of this Lease. The adequate assurance to be provided Landlord to assure the assignee’s future performance under the Lease shall include without limitation:

(A)the deposit of a sum equal to three (3) months’ Rent to be held (without any allowance for interest thereon) as security for performance hereunder; and

(B)a written demonstration that the assignee meets all reasonable financial and other criteria of Landlord as did Tenant and its business at the time of execution of this Lease, including the production of the most recent audited financial statement of the assignee prepared by a certified public accountant; and

(C)the assignee’s use of the Premises will be in compliance with the terms of Article 5.00 of this Lease; and

(D)assurances, in a form acceptable to Landlord, as to all matters identified in any applicable provision of the Bankruptcy Code.

21.01.Limitation of Responsibility. Tenant acknowledges and agrees that all telephone and telecommunications services desired by Tenant shall be ordered and utilized at the sole expense of Tenant. Unless Landlord otherwise requests or consents in writing, all of Tenant’s telecommunications

equipment (other than connections) shall be and remain solely in Tenant’s Premises, in accordance with rules and regulations adopted by Landlord from time to time. Unless otherwise specifically agreed to in writing, Landlord shall have no responsibility for the maintenance of Tenant’s telecommunications equipment, including wiring; or for any wiring or other infrastructure to which Tenant’s telecommunications equipment may be connected. Tenant agrees that, to the extent any such service is interrupted, curtailed, or discontinued, Landlord shall have no obligation or liability with respect thereto, except to the extent caused by the gross negligence or intentional misconduct of Landlord, its employees, agents or contractors. In no event shall Landlord be subject to consequential, special or punitive damages as a result of any such interruption for whatever reason. It shall be the sole obligation of Tenant at its expense to obtain substitute service. Notwithstanding the foregoing, Tenant shall have the right to access the Building riser system to install its telecommunication cabling at no additional cost, provided such installation does not interfere with other telecommunication systems, is coordinated with Landlord, and does not exceed Tenant’s pro rata share of the riser space.

21.02.Necessary Service Interruptions. Landlord shall have the right, upon reasonable prior notice to Tenant, to temporarily interrupt or turn off telecommunications facilities in the event of emergency or as necessary in connection with repairs to the Building or Project or installation of telecommunications equipment for other tenants of the Building or Project. In the event of an emergency, Landlord shall provide Tenant as much advance notice as possible. Landlord shall exercise commercially reasonable efforts to perform any work necessary to restore telecommunications services or facilities as quickly as possible and to perform any scheduled shutdowns during non-business hours.

21.03.Removal of Equipment, Wiring, and Other Facilities. Any and all telecommunications equipment installed in Tenant’s Premises or elsewhere in the Project, by or on behalf of Tenant, including wiring, or other facilities for telecommunications transmittal, shall be removed within five (5) business days after the expiration or earlier termination of the Term by Tenant at its sole cost or, at Tenant’s ‘s election, by Landlord at Tenant’s sole cost, with the reasonable cost thereof to be paid as additional rent. Landlord shall have the right, however, upon written notice to Tenant given no later than thirty (30) days prior to the expiration or earlier termination of the Lease term, to require Tenant to abandon and leave in place, without additional payment to Tenant or credit against rent, any and all telecommunications wiring and related infrastructure, or selected components thereof, whether located in Tenant’s Premises or elsewhere in the Project.

21.04.New Provider Installations. In the event that Tenant wishes at any time to utilize the services of a telephone or telecommunications provider whose equipment is not then servicing the Project, or to materially expand the services or infrastructure of a provider currently providing service to the Project, no such provider shall be permitted to install its lines or other equipment within the Project without first securing the prior written approval of Landlord. Landlord’s approval shall not be deemed any kind of warranty or representation by Landlord, including, without limitation, any warranty or representation as to the suitability, competence, or financial strength of the provider. Without limitation of the foregoing standard, it shall be reasonable for Landlord to refuse to give its approval unless all of the following conditions are satisfied to Landlord’s satisfaction:

(a)Landlord shall incur no expense whatsoever with respect to any aspect of the provider’s provision of its services, including, without limitation, the costs of installation, materials, and services;

(b)prior to commencement of any work in or about the Project by the provider, the provider or Tenant shall supply Landlord with such written reasonable indemnities, insurance, financial statements, and such other items as Landlord reasonably determines to be necessary to protect its financial interests and the interests of the Building relating to the proposed activities of the provider;

(c)the provider agrees to abide by such rules and regulations, building and other codes, job site rules, and such other requirements as are reasonably determined by Landlord to be necessary to protect the interests of the Project, the tenants in the Project, and Landlord, in the same or similar manner as Landlord has the right to protect itself and the Project with respect to proposed alterations as described in this Lease;

(d)Landlord reasonably determines that there is sufficient space in the Project for the placement of the provider’s equipment and materials;

(e)the provider agrees to abide by Landlord’s requirements, if any, that provider use existing building conduits and pipes or use building contractors (or other contractors approved by Landlord);

(f)Landlord receives from the provider or Tenant such compensation as is reasonably determined by Landlord to compensate it for space used in the Building and/or Project for the storage and maintenance of the provider’s equipment, for the fair market value of a provider’s access to

the Building and/or Project, and the costs which may reasonably be expected to be incurred by Landlord;

(g)the provider agrees to deliver to Landlord detailed “as built’ plans immediately after the installation of the provider’s equipment is complete; and

(h)all of the foregoing matters are documented in a written license agreement between Landlord and the provider, the form and content of which are reasonably satisfactory to Landlord.

21.05.Provider License Expiration. If the license between any provider and Landlord shall terminate by natural expiration, Landlord shall exercise reasonable efforts to notify Tenant at least thirty (30) days before the expiration so Tenant may arrange for alternative service. If Landlord does not receive advance notice from the provider, or the license expires for any other reason, Landlord shall have no obligation to Tenant.

21.06.Limit of Default or Breach. Notwithstanding any provision of the proceeding paragraphs to the contrary, the refusal of Landlord to grant its approval to any prospective telecommunications provider shall not be deemed a default or breach by Landlord of its obligation under this Lease and until Landlord is adjudicated to have acted grossly negligent with respect to Tenant’s request for approval, and in that event, Tenant shall still have no right to terminate the Lease or claim an entitlement to rent abatement, but may, as Tenant’s sole and exclusive recourse, seek a judicial order of specific performance compelling Landlord to grant its approval as to the prospective provider in question. The provisions of this paragraph may be enforced solely by Tenant and Landlord, are not for the benefit of any other party (including any subtenant), and specifically, but without limitation, no telephone or telecommunications provider shall be deemed a third party beneficiary of this Lease.

21.07.Installation and Use of Wireless Technologies. Tenant shall not utilize any wireless communications equipment (other than usual and customary cellular telephones and wireless computer networks or internet service dedicated to Tenant’s sole use), including antennae and satellite receiver dishes, within Tenant’s Premises, the Building, and/or the Project without Landlord’s prior written consent. Such consent may be reasonably conditioned in such a manner so as to protect Landlord’s financial interests and the interests of the Project, and the other tenants therein, in a manner similar to the arrangements described in the immediately preceding paragraphs.

21.08.Limitation. Except as otherwise agreed to in writing between Landlord and Tenant, Tenant shall not knowingly use or permit the use of the Premises for the sale, lease, license, or otherwise of electronic commerce services to any tenants or occupants in the Building, including, but not limited to, hardware and software services that allow users to conduct business-to-business or business-to consumer services over networks utilizing, by way of example, e-mail, electronic data interchange, data archiving, e-forms, electronic file transfer, facsimile transfers, and similar services or any other services not expressly permitted under the Lease. For avoidance of doubt, Landlord hereby acknowledges that Tenant’s business includes providing a mobile consumer application or “app” to its users, which may include occupants of the Project, and Landlord hereby agrees that Tenant’s mobile consumer app does not violate this Section 21.08 and expressly consents to the same.

21.09.Limitation of Liability For Equipment Interference. In the event that telecommunications equipment, wiring, and facilities or satellite and antennae equipment of any type installed by or at the request of Tenant within Tenant’s Premises, on the roof, or elsewhere within or on the Project (other than usual and customary cellular telephones and wireless computer networks or internet service dedicated to Tenant’s sole use) causes interference to equipment used by another party, Tenant shall assume all liability related to such interference. Tenant shall use reasonable efforts, and shall cooperate with Landlord and other parties, to promptly eliminate such interference. In the event that Tenant is unable to do so, Tenant will substitute alternative equipment which remedies the situation. If such interference persists, Tenant shall discontinue the use of such equipment and, at Landlord’s discretion, remove such equipment according to the foregoing specifications.

22.01.Improvement Allowance. In addition to the obligation of Landlord to perform “Landlord’s Work” as provided in Section 22.02 below, Landlord shall provide to Tenant an improvement allowance (“Allowance”) in an amount equal to Two Million Seventy Four Thousand and Fifty and no/100 Dollars ($2,074,050.00), based on $55.00 per rentable square foot of space in the Premises, for the contribution toward the cost of demolition and/or construction of the Tenant’s improvements to the Premises (“Tenant’s Work”), as well as design and engineering fees, architectural and space planning services, and municipal plan review and permit fees (collectively “Improvements”), including the right to use the Allowance, for project management fees, but expressly excluding legal fees and personal property (i.e., furniture) based on a mutually agreed upon space plan (“Space Plan”) and in accordance with Exhibit D. Notwithstanding the foregoing, Tenant shall have the right to apply any unused portion of the Allowance up to Ten and

no/100 Dollars ($10.00) per rentable square foot, towards Tenant’s data/telecom cabling and installation costs, moving expenses of any kind or nature, fixtures, equipment, and security system (“Moving Costs”). During the construction of the Improvements, Landlord will make available (at no cost to Tenant) Building services, including HVAC, electrical to the Premises and access to the Building’s freight elevator, provided Tenant (or its designee) coordinates with Landlord, a schedule for such times and in a manner that will not unreasonably interfere with Landlord’s general operation of the Building.

Tenant shall have the right to select its own architect. Tenant shall select a contractor and subcontractors from Landlord’s approved contractors list, or as otherwise approved by Landlord. Tenant shall be obligated to utilize BCER Engineers for Tenant’s mechanical, electrical work, and plumbing design, and Martin/Martin for all structural design, including the reinforcing of the floor (if required) in areas reasonably approved by Landlord, so long as the fees charged by BCER Engineers and Martin/Martin do are comparable to the market rates for similar services by comparable professionals in comparable class office buildings in the Central Business District. Tenant shall have the right to request the Allowance in three installments upon completion of 35%, 70% and 100% of the Improvements, and upon satisfaction of the following items for each draw request: (i) Tenant delivers a schedule of values and shows in reasonable detail the completion of the portion of Improvements is proportionate to the amount of the Allowance draw request in a form reasonably satisfactory to Landlord; (ii) Tenant delivers to Landlord properly executed conditional mechanics’ lien waivers from all of Tenant’s contractors and subcontractors in compliance with all applicable laws; and (iii) Tenant delivers to Landlord a certificate signed by Tenant’s architect (AIA Application for Payment or substantially similar form), in a form reasonably acceptable to Landlord, certifying that the construction of the applicable part of the Improvements in the Premises has been completed. Provided that Tenant is not in default beyond any applicable notice and cure period at any draw request, then within thirty (30) days after satisfaction of items (i) through (iii) above, Landlord shall pay to Tenant all amounts shown in (i) above. Tenant may also request reimbursement of Moving Costs in the abovereferenced Allowance installments; provided that the requirements of subsections (i) through (iii) above shall not apply to any request for reimbursement of Moving Costs. All requests for reimbursement in connection with the completion of the Improvements shall be submitted by Tenant to Landlord as provided herein, but in no case later than two hundred and ten (210) days following the Commencement Date. In the event Tenant fails to submit invoices for reimbursement on or before the expiration of such two hundred and ten (210) day period, Tenant shall forfeit its right to any portion of the Allowance not requested prior to the expiration of such 210 day period. Tenant shall pay to

Landlord, which amount may be deducted by Landlord from the Allowance, a fee equal to one percent (1%) of the “hard costs” of Tenant’s Work for Landlord’s supervision of Tenant’s construction of the Premises to ensure code compliance, structural integrity of the Improvements, and coordination of Tenant’s Work within the Building. In addition to the Allowance, Landlord will provide Tenant twelve cents ($.12) per rentable square foot for a space planning allowance, which amount shall be paid by directly to Tenant’s space planner, within thirty (30) days of receipt from Tenant of an invoice from Tenant’s architect for such space planning.

22.02.Landlord’s Work. At Landlord’s sole cost and expense, Landlord shall be responsible for renovating the men’s and women’s restrooms on the 4th floor of the Building to current ADA compliant standards.

Attention:     Brett L. Gross, Esq.

This Subordination, Non-Disturbance and Attornment Agreement (“Agreement”), is made as of this ____ day of _____________, 2015 among ROYAL BANK OF CANADA, as administrative agent for (and for the benefit of) itself and one or more co-lenders (together with its successors, assigns and/or affiliates in such capacity as administrative agent, “Administrative Agent”), BOP 1801 CALIFORNIA STREET LLC and BOP 1801 CALIFORNIA STRET II LLC, both Delaware limited liability companies (“Landlord”), and ________________________________, a _______________________________ (“Tenant”).

A.Royal Bank of Canada and/or one or more co-lenders has made or will make a loan to Landlord in the maximum principal amount of $206,500,000 (“Loan”), which is secured by a mortgage, deed of trust or similar security instrument (as the same may be amended, supplemented, extended, renewed, restated, replaced, substituted or otherwise modified from time to time, including without limitation, modifications which increase the principal amount secured thereby, the “Security Instrument”) on Landlord’s property described more particularly on Exhibit 1 attached hereto (“Property”).

B.Tenant is the present lessee under that certain lease agreement between Landlord and Tenant dated ________, 2015, as thereafter modified and supplemented (“Lease”), demising a portion of the Property described more particularly in the Lease (“Leased Space”).

C.A requirement of the Loan is that Tenant’s Lease be subordinated to the Security Instrument. Landlord has requested Tenant to so subordinate the Lease in exchange for Administrative Agent’s agreement not to

disturb Tenant’s possession of the Leased Space upon the conditions set forth in this Agreement.

NOW, THEREFORE, in consideration of the mutual promises of this Agreement, and intending to be legally bound hereby, the parties hereto agree as follows:

1.Subordination. Tenant agrees that the Lease and all of the terms, covenants and provisions thereof, and all estates, options and rights created under the Lease, hereby are subordinated and made subject to the lien and effect of the Security Instrument (including, without limitation, all renewals, increases, modifications, spreaders, consolidations, replacements and extensions thereof), as if the Security Instrument had been executed and recorded prior to the Lease.

2.Nondisturbance. Administrative Agent agrees that no foreclosure (whether judicial or nonjudicial), deed-in-lieu of foreclosure, or other sale of the Property in connection with enforcement of the Security Instrument or otherwise in satisfaction of the Loan shall operate to terminate the Lease or Tenant’s rights thereunder to possess and use the Leased Space provided, however, that (a) the term of the Lease has commenced, (b) Tenant is in possession of the Leased Space, and (c) the Lease is in full force and effect and no uncured default exists under the Lease.

3.Attornment. Tenant agrees to attorn to and recognize as its landlord under the Lease each party acquiring legal title to the Property by foreclosure (whether judicial or nonjudicial) of the Security Instrument, deed-in-lieu of foreclosure, or other sale in connection with enforcement of the Security Instrument or otherwise in satisfaction of the Loan (“Successor Owner”). Provided that the conditions set forth in Section 2 above are met at the time Successor Owner becomes owner of the Property, Successor Owner shall perform all obligations of the landlord under the Lease arising from and after the date title to the Property is transferred to Successor Owner. In no event, however, will any Successor Owner be: (a) liable for any default, act or omission of any prior landlord under the Lease; (b) subject to any offset or defense which Tenant may have against any prior landlord under the Lease; (c) bound by any payment of rent or additional rent made by Tenant to Landlord more than 30 days in advance; (d) bound by any modification or supplement to the Lease, or waiver of Lease terms, made without Administrative Agent’s written consent thereto; (e) liable for the return of any security deposit or other prepaid charge paid by Tenant under the Lease, except to the extent such amounts were actually received by Administrative Agent; (f) liable or bound by any right of first refusal or option to purchase all or any portion of the Property; or (g) liable for construction or completion of any improvements to the Property or as required under the Lease for Tenant’s use and occupancy (whenever arising). Although the foregoing provisions of this Agreement are self-operative, Tenant agrees to execute and deliver to Administrative Agent or any Successor Owner such

further instruments as Administrative Agent or a Successor Owner may from time to time request in order to confirm this Agreement. If any liability of Successor Owner does arise pursuant to this Agreement, such liability shall be limited to Successor Owner’s interest in the Property.

4.Prior Assignment; Rent Payments; Notice to Tenant Regarding Rent Payments. Tenant has no knowledge of any prior assignment or pledge of the rents accruing under the Lease by Landlord. Tenant hereby acknowledges and consents to that certain Assignment of Leases and Rents from Landlord to Administrative Agent executed in connection with the Loan. Tenant acknowledges that the interest of the Landlord under the Lease is to be assigned to Administrative Agent solely as security for the purposes specified in said assignment, and Administrative Agent shall have no duty, liability or obligation whatsoever under the Lease or any extension or renewal thereof, either by virtue of said assignments or by any subsequent receipt or collection of rents thereunder, unless Administrative Agent shall specifically undertake such liability in writing. Tenant agrees not to pay rent more than one (1) month in advance unless otherwise specified in the Lease. After notice is given to Tenant by Administrative Agent that Landlord is in default under the Security Instrument and that the rentals under the Lease are to be paid to Administrative Agent directly pursuant to the assignment of leases and rents granted by Landlord to Administrative Agent in connection therewith, Tenant shall thereafter pay to Administrative Agent all rent and all other amounts due or to become due to Landlord under the Lease. Landlord hereby expressly authorizes Tenant to make such payments to Administrative Agent upon reliance on Administrative Agent’s written notice (without any inquiry into the factual basis for such notice or any prior notice to or consent from Landlord) and hereby releases Tenant from all liability to Landlord in connection with Tenant’s compliance with Administrative Agent’s written instructions.

5.Administrative Agent Opportunity to Cure Landlord Defaults. Tenant agrees that, until the Security Instrument is released by Administrative Agent, it will not exercise any remedies under the Lease following a Landlord default without having first given to Administrative Agent (a) written notice of the alleged Landlord default and (b) the opportunity to cure such default within the longer of (i) 30 days after the cure period provided under the Lease to Landlord, (ii) 30 days from Landlord’s receipt of Tenant’s notice to Administrative Agent of a Landlord default, or (iii) if the cure of such default requires possession of the Property, 30 days after Administrative Agent has obtained possession of the Property; provided that, in each case, if such default cannot reasonably be cured within such 30-day period and Administrative Agent has diligently commenced to cure such default promptly within the time contemplated by this Agreement, such 30-day period shall be extended for so long as it shall require Administrative Agent, in the exercise of due diligence, to cure such default, but, unless the parties otherwise agree, in no event shall the entire cure period be more than 120 days. Tenant acknowledges that Administrative Agent is not obligated to cure any Landlord default, but if Administrative Agent elects

to do so, Tenant agrees to accept cure by Administrative Agent as that of Landlord under the Lease and will not exercise any right or remedy under the Lease for a Landlord default. Performance rendered by Administrative Agent on Landlord’s behalf is without prejudice to Administrative Agent’s rights against Landlord under the Security Instrument or any other documents executed by Landlord in favor of Administrative Agent in connection with the Loan.

6.Right to Purchase. Tenant covenants and acknowledges that it has no right or option of any nature whatsoever, whether pursuant to the Lease or otherwise, to purchase the Property or the real property of which the Property is a part, or any portion thereof or any interest therein and to the extent that Tenant has had, or hereafter acquires any such right or option, the same is hereby acknowledged to be subject and subordinate to the Security Instrument and is hereby waived and released as against Administrative Agent.

7.Miscellaneous.

(a)Notices. All notices and other communications under this Agreement are to be in writing and addressed as set forth below such party’s signature hereto. Default or demand notices shall be deemed to have been duly given upon the earlier of: (i) actual receipt; (ii) one (1) business day after having been timely deposited for overnight delivery, fee prepaid, with a reputable overnight courier service, having a reliable tracking system; (iii) one (1) business day after having been sent by telecopier (with answer back acknowledged) provided an additional notice is given pursuant to (ii); or (iv) three (3) business days after having been deposited in any post office or mail depository regularly maintained by the U.S. Postal Service and sent by certified mail, postage prepaid, return receipt requested, and in the case of clause (ii) and (iv) irrespective of whether delivery is accepted. A new address for notice may be established by written notice to the other parties; provided, however, that no address change will be effective until written notice thereof actually is received by the party to whom such address change is sent.

(b)Entire Agreement; Modification. This Agreement is the entire agreement between the parties hereto with respect to the subject matter hereof, and supersedes and replaces all prior discussions, representations, communications and agreements ( oral or written). This Agreement shall not be modified, supplemented, or terminated, nor any provision hereof waived, except by a written instrument signed by the party against whom enforcement thereof is sought, and then only to the extent expressly set forth in such writing.

(c)Binding Effect:, Joint and Several Obligations. This Agreement is binding upon and inures to the benefit of the parties hereto and their respective heirs, executors, legal representatives, successors, and assigns, whether by voluntary action of the parties or by operation of law. No Indemnitor may delegate or transfer its obligations under this Agreement.

(d)Unenforceable Provisions. Any provision of this Agreement which is determined by a court of competent jurisdiction or government body to be invalid, unenforceable or illegal shall be ineffective only to the extent of such determination and shall not affect the validity, enforceability or legality of any other provision, nor shall such determination apply in any circumstance or to any party not controlled by such determination.

(e)Duplicate Originals:, Counterparts. This Agreement may be executed in any number of duplicate originals, and each duplicate original shall be deemed to be an original. This Agreement (and each duplicate original) also may be executed in any number of counterparts, each of which shall be deemed an original and all of which together constitute a fully executed Agreement even though all signatures do not appear on the same document.

(f)Construction of Certain Terms. Defined terms used in this Agreement may be used interchangeably in singular or plural form, and pronouns shall be construed to cover all genders. Article and section headings are for convenience only and shall not be used in interpretation of this Agreement. The words “herein,” “hereof” and “hereunder” and other words of similar import refer to this Agreement as a whole and not to any particular section, paragraph or other subdivision; and the word “section” refers to the entire section and not to any particular subsection, paragraph of other subdivision; and “Agreement” and each of the Loan Documents referred to herein mean the agreement as originally executed and as hereafter modified, supplemented, extended, consolidated, or restated from time to time.

(g)Governing Law. This Agreement shall be interpreted and enforced according to the laws of the State where the Property is located (without giving effect to its rules governing conflict of laws).

(h)Consent to Jurisdiction. Each party hereto irrevocably consents and submits to the exclusive jurisdiction and venue of any state or federal court sitting in the county and state where the Property is located with respect to any legal action arising with respect to this Agreement and waives all objections which it may have to such jurisdiction and venue.

(i)WAIVER OF JURY TRIAL. TO THE FULLEST EXTENT PERMITTED BY LAW, EACH PARTY HERETO WAIVES AND AGREES NOT TO ELECT A TRIAL BY JURY WITH RESPECT TO ANY ISSUE ARISING OUT OF THIS AGREEMENT.
