AGREEMENT

NOW, THEREFORE, in consideration of the mutual covenants, terms and conditions set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

1.Demise and Existing FF&E. Subject to the terms below, Sublandlord hereby leases to Subtenant, and Subtenant hereby leases from Sublandlord, the entire Demised Premises (also referred to herein as the “Subleased Premises”) as more particularly shown on Exhibit A attached to and made a part of this Sublease, together with the right to use the common areas of the Building as described in the Primary Lease. Sublandlord and Subtenant agree that the Rentable Area is conclusive for all purposes of this Sublease and is not subject to remeasurement.

(b)If for any reason the term of the Primary Lease is terminated prior to the Sublease Expiration Date, this Sublease shall automatically terminate on the date of such termination and, unless resulting from a default by Sublandlord under this Sublease and/or the Primary Lease, Sublandlord shall not be liable to Subtenant for such termination.

3.Permitted Use. Subtenant shall use and occupy the Subleased Premises solely in accordance with, and as permitted under, the terms of the Primary Lease and for no other purpose. Subtenant shall (i) not conduct, nor permit to be conducted, on the Subleased Premises, any business which is in violation of any law or governmental regulation, and (ii) to the extent the responsibility of Sublandlord under the Primary Lease and provided Sublandlord delivers the Subleased Premises in the condition required hereunder, maintain the Subleased Premises in accordance with the terms of the Primary Lease.

Payment of Base Rent and Additional Rent.

(a)Throughout the Sublease Term, Subtenant shall pay to Sublandlord fixed base rent (“Base Rent”) at the rate of: (i) $59,464.50 per month on a full-service basis from the Sublease Commencement Date to the Sublease Expiration Date, payable in equal monthly installments, in advance, on the first day of each calendar month during the Sublease Term, pro rated on a per diem basis for any partial calendar month(s). The Base Rent shall be subject to an annual three (3%) percent escalation effective on each anniversary of Sublease Commencement Date, as more particularly set forth on the Base Rent table attached hereto as Schedule II. Subtenant shall pay to Sublandlord the first monthly installment of Base Rent concurrently with the execution and delivery of this Sublease by Subtenant to Sublandlord. Notwithstanding anything to the contrary herein, the Base Rent shall be abated in full for the first three full calendar months of the Sublease Term.

(b)In addition to Base Rent, commencing on the Sublease Commencement Date and continuing throughout the Sublease Term, Subtenant shall pay to Sublandlord at the place where Base Rent is payable all Direct Expenses and all other Additional Rent payable by Sublandlord under the Primary Lease. For all such Additional Rent, Sublandlord will be responsible for any underpaid amounts, as well as entitled to reimbursement of overpaid amounts, relating to the period prior to the Sublease Commencement Date. Subtenant will be responsible for any underpaid amounts, as well as entitled to reimbursement of overpaid amounts, first arising or accruing during the period from and after the Sublease Commencement Date. Notwithstanding the foregoing or anything herein to the contrary, rent under this Sublease shall not include, and Subtenant shall have no responsibility or liability for the payment of any cost, expense, and/or charge arising from Sublandlord’s failure to perform its obligations under this Sublease or the Primary Lease.

(c)All Base Rent and Additional Rent shall be due and payable without demand therefor and without any deduction, offset, abatement, counterclaim or defense, except as otherwise expressly set forth herein. The monthly installments of Base Rent and Additional Rent payable on account of any partial calendar month during the Sublease Term, if any, shall be prorated on a per diem basis. Subtenant shall make payment for such rent by ACH payment or electronic funds transfer, provided that Sublandlord has provided its account information. Any rent paid directly by Subtenant to Prime Landlord at Prime Landlord’s or Sublandlord’s request shall be credited to Subtenant’s corresponding rent obligation under this Sublease.

5.Security Deposit. Simultaneously with the execution and delivery of this Sublease, Subtenant shall deposit with Sublandlord a security deposit (“Security Deposit”) in the amount of One Hundred Fifty Thousand and 00/100 Dollars ($150,000.00) in cash as security for the full and faithful performance by Subtenant of Subtenant’s obligations hereunder. Sublandlord shall return the Security Deposit, reduced by the amounts, if any, that have been applied to remedy defaults of this Sublease by Subtenant, to Subtenant within ten (10) business days after the expiration or earlier termination of this Sublease.

Incorporation of Primary Lease by Reference.

(a)The terms, covenants and conditions of the Primary Lease are incorporated herein by reference, except to the extent they are expressly deleted or modified by the provisions of this Sublease. Except as set forth herein, every term, covenant and condition of the Primary Lease binding upon or inuring to the benefit of Prime Landlord shall, in respect of this Sublease, be binding upon or inure to the benefit of Sublandlord and every term, covenant and condition of the Primary Lease binding upon or inuring to the benefit of Sublandlord shall, in respect of this Sublease, be binding upon and inure to the benefit of Subtenant. Whenever the term “Lessor” or “Landlord” appears in the Primary Lease, the word “Sublandlord” shall be substituted therefor; whenever the term “Lessee” or

“Tenant” appears in the Primary Lease, the word “Subtenant” shall be substituted therefor; whenever the word “Premises” appears in the Primary Lease, the word “Subleased Premises” shall be substituted therefor. With respect to work, services, and utilities that are obligations of Prime Landlord under the Primary Lease, the sole responsibility of Sublandlord shall be to use commercially reasonable efforts to obtain Prime Landlord’s performance

(b)Notwithstanding the foregoing, (i) the following numbered paragraphs of the Primary Lease shall not apply to this Sublease: The Summary of Basic Lease Information, excepting Sections 2, 7 and 12; Section 1.3 (Right of First Offer), Section 2.2 (Occurrence of Delivery Date); Article 3 (Base Rent), Article 14 (Assignment and Subletting) other than Section 14.8, Section 18.2 ((Notice to Lienholder or Ground Lessor), Article 20 (Covenant of Quiet Enjoyment), Article 21 (Letter of Credit), Article 23 (Signs), Article 28 (Notices), Section 29.24 (Brokers), Section 29.29 (Development of the Project), Exhibits B and H of the Original Primary Lease, the first sentence of Section 1 and Sections 2, 3, 4, 5, and 6 of the First Amendment to Original Primary Lease, and the first sentence of Section 1 and Sections 2.a, 5, 6 and 7 of the Second Amendment to Original Primary Lease, and (ii) the time limits contained in the Primary Lease for Sublandlord, as tenant, to give notices, make demands or perform any act, covenant or condition or to exercise any right, remedy or option, are modified herein by shortening the same in each instance by two (2) days, and (iii) references in the following sections of the Primary Lease to “Landlord” shall refer only to Prime Landlord (as opposed to Prime Landlord and Sublandlord): Article 6, Sections 10.1 and 10.12, and the first sentence of Section 3 of the Second Amendment to Original Primary Lease. If any of the express provisions of this Sublease shall conflict with any of the provisions of the Primary Lease, the provisions of this Sublease shall govern as between Sublandlord and Subtenant.

7.Subordination to Primary Lease. This Sublease and all of Subtenant’s rights hereunder are subject and subordinate to the Primary Lease. So long as Subtenant is not in default hereunder (beyond applicable notice and cure periods), Sublandlord shall not terminate the Primary Lease without the prior consent of Subtenant (which may be granted or withheld in Subtenant’s sole discretion) unless Prime Landlord agrees to recognize Subtenant as a direct tenant on the terms of this Sublease in conjunction with such termination.

8.Reimbursement. If Sublandlord is required by Prime Landlord pursuant to the terms of the Prime Lease to reimburse Prime Landlord for expenditures made by Prime Landlord resulting from Subtenant’s breach of the terms of this Sublease, Subtenant shall pay to Sublandlord all amounts demanded by Prime Landlord no later than the earlier of (i) thirty (30) days after written demand by Sublandlord, which demand shall include reasonable supporting documentation therefor, and (ii) two (2) days prior to the date when such payment is required to be made by Sublandlord to Prime Landlord.

9.AS-IS Condition. Subtenant acknowledges that, except as set forth in this Sublease, neither Sublandlord nor any of Sublandlord’s agents, employees or representatives have made any representation or warranty, either express or implied, with respect to the Premises, the condition of the Premises or the use of the Premises by Subtenant, and Subtenant accepts the Subleased Premises in its current, “as-is” “where is” and “with all faults” condition. Sublandlord shall have no obligation to furnish or supply any work, services, furniture, fixtures, equipment or decorations, provided, however, that Sublandlord shall deliver the Subleased Premises in broom clean condition with all systems in good working order and condition. On or before the Sublease Expiration Date or earlier termination or expiration of this Sublease, Subtenant shall restore the Subleased Premises to the condition existing as of the Sublease Commencement Date, ordinary wear and tear, damage from casualty and condemnation, and, except to the extent removal is required by Prime Landlord, permitted alterations and improvements excepted. The obligations of Subtenant hereunder shall survive the expiration or earlier termination of this Sublease.

10.Performance By Sublandlord. Notwithstanding any other provision of this Sublease but provided Sublandlord delivers the Subleased Premises and the Existing FF&E in the condition required hereunder, Sublandlord shall have no obligation (a) to furnish or provide, or cause to be furnished or provided, any repairs, restoration, alterations or other work, or electricity, heating, ventilation, air- conditioning, water, elevator, cleaning or other utilities or services, or (b) to comply with or perform or, except as expressly provided in this Sublease, to cause the compliance with or performance of, any of the terms and conditions required to be performed by Prime Landlord pursuant to the terms of the Primary Lease. Subtenant hereby agrees that Prime Landlord is solely responsible for the performance of the foregoing obligations. Notwithstanding the foregoing, upon the written request of Subtenant, Sublandlord shall make written demand upon and otherwise use commercially reasonable efforts to cause Prime Landlord to perform its obligations under the Primary Lease with respect to the Subleased Premises if Prime Landlord fails to perform same within the time frame and in the manner required pursuant to the Primary Lease provided, however, Sublandlord shall not be required to bring any action against the Prime Landlord to enforce its obligations; further provided, however, that if Primary Landlord defaults under the Primary Lease or fails to perform any of its

obligations under the Primary Lease after receipt of written notice from Sublandlord of such failure, Sublandlord shall either institute legal proceedings against Primary Landlord directly or assign Sublandlord's rights under the Primary Lease to Subtenant to the extent necessary to permit Subtenant to institute legal proceedings against Primary Landlord to obtain performance of Primary Landlord’s obligations under the Primary Lease; provided Subtenant agrees to indemnify and hold harmless Sublandlord for all claims, liabilities and damages that Sublandlord may sustain as a result of, arising out of, or in connection therewith and pays Sublandlord all costs and expenses reasonably incurred by Sublandlord in connection therewith. In the event Sublandlord brings an action against Prime Landlord to enforce Prime Landlord’s obligations under the Primary Lease with respect to the Subleased Premises, all costs and expenses (including, without limitation, reasonable attorneys’ fees and expenses) incurred by Sublandlord in connection therewith shall be deemed Additional Rent and shall be due and payable by Subtenant to Sublandlord within thirty (30) days of demand (which shall include reasonable supporting documentation) therefor. This Section 10 shall survive the expiration or earlier termination of the Sublease Term.

11.No Privity of Estate; No Privity of Contract. Nothing in this Sublease shall be construed to create privity of estate or privity of contract between Subtenant and Prime Landlord.

12.No Breach of Primary Lease. Subtenant shall not do or permit (by its agents, employees and contractors) to be done any act or thing, or omit to do anything required of it by the terms of this Sublease, which may constitute a breach or violation of any term, covenant or condition of the Primary Lease, notwithstanding such act, thing or omission is permitted under the terms of this Sublease.

13.Subtenant Defaults. If Subtenant fails to cure a default under this Sublease within any applicable notice, grace or cure period contained in the Primary Lease (as such applicable notice, grace or cure period is modified by Section 6 herein), Sublandlord shall have the right, but not the obligation, to seek to remedy any such default on the behalf of, and at the expense of, Subtenant, on the terms of Article 19 of the Primary Lease, as incorporated herein. Any reasonable out-of-pocket cost and expense (including without limitation reasonable attorneys’ fees and expenses) actually incurred by Sublandlord shall be deemed Additional Rent and shall be due and payable by Subtenant to Sublandlord within thirty (30) days after notice from Sublandlord. If Sublandlord actually receives under the Primary Lease an abatement of rent or any portion thereof resulting from any casualty, condemnation, interruption of services, of default by Prime Landlord, then Subtenant shall be entitled to receive from Sublandlord the same such abatement.

14.Consents. Whenever the consent or approval of Sublandlord is required under this Sublease, to the extent Prime Landlord’s consent or approval is also required pursuant to the terms of the Primary Lease, Sublandlord shall promptly make such consent or approval request of Prime Landlord and use commercially reasonable efforts to obtain such consent or approval, and Subtenant shall use commercially reasonable efforts to promptly provide any information or documentation that Prime Landlord may request in connection therewith. Subtenant shall reimburse Sublandlord, not later than thirty (30) days after written demand by Sublandlord, for any actual and reasonable fees and disbursements of attorneys, architects, engineers or others charged by Prime Landlord in connection with any such consent or approval. Sublandlord shall have no liability of any kind to Subtenant for Prime Landlord’s failure to give its consent or approval so long as Sublandlord uses commercially reasonable efforts to obtain the same. In no event shall Subtenant or Sublandlord be liable to the other for any consequential, special or punitive damages arising out of or in connection with this Sublease, except to the extent Sublandlord is obligated to Prime Landlord for the same as a result of Subtenant’s default under this Sublease.
