It is expressly understood and agreed that the Sublessee may not assign this Sublease or sublet all or any portion of the Demised Premises or permit any person, firm or corporation to occupy any portion of the Demised Premises as licensee or in any other fashion without the prior written consent of the Sublessor.

In the case of an assignment, the proposed assignee must specifically assume and agree in writing to be bound by all of the obligations of the Sublessee hereunder. 10. The Sublessee agrees to hold harmless and indemnify the Sublessor of and from all damages, costs and expenses and losses which the Sublessor may incur under the Prime Lease or for which Sublessor may be liable to Prime Landlord by reason of the Sublessee's default hereunder which are the subject matter of any indemnity or hold harmless of Sublessor to Prime Landlord under the Prime Lease or which would constitute a default on the part of the Sublessor under said Prime Lease. The Sublessor agrees to hold harmless and indemnify the Sublessee of and from all damages, costs and expenses which the Sublessee may incur under the Prime Lease or for which Sublessee may be liable to Prime Landlord by reason of Sublessor's default hereunder which are the subject matter of any indemnity or hold harmless of Sublessor to Prime Landlord under the Prime Lease would constitute a default of the Sublessor under the Prime Lease. 11. The Sublessee shall indemnify and hold harmless the Sublessor from and against the claims and demands of all persons on account of injury to person, including death and including employees of the said Sublessee or damage to property occurring on or in the Demised Premises unless such injury or damage shall be due solely to the act of the Sublessor or its employees. 12. Sublessee shall pay for any additional insurance premiums which shall be charged to Sublessor by reason of Sublessee's occupancy of the Subleased Premises. 13. The Sublessee agrees that Sublessee has inspected the Demised Premises, found the same to be acceptable in all respects, and acknowledges that neither of Prime Landlord nor Sublessor shall have any responsibility to make repairs or improvements to comply with Sublessor's obligations to deliver the Subleased Premises to the Sublessee. Any alterations or additions to the Demised Premises shall be at the sole expense of the Sublessee and shall require the approval of the Sublessor (and the Prime Landlord if required under the terms of the Prime Lease). By acceptance of this Sublease, Sublessor agrees that any alterations or additions approved by Prime Landlord and Sublessor need not be removed at the termination of the Prime Lease or Sublease unless such removal is made a condition of such approval. Sublessee has advised Sublessor that it intends to subdivide the existing conference room in the Demised Premises to create two individual 3 offices by installing a non-structural partition wall. Subject to Sublessor's review and approval of architectural plans therefore, and reserving it rights to condition its approval on the subsequent restoration of the Demised Premises, the Sublessor acknowledges that it has no objection to Sublessee's proposed alterations as aforesaid. 14. Without limiting the generality of Section 4 of this Sublease, Sublessee agrees to pay to the Sublessor the following: (a) all charges for electricity as set forth in Section 4.4 of the Prime Lease; (b) Tenant's Share of Premises Expenses as set forth in Section 4.2 of the Prime Lease, including any Estimated Premises Expense Payments required under Section 4.3 of the Prime Lease. All of the foregoing payments shall be made by the Sublessee at the time and in the manner required of Sublessor under the Prime Lease. 15. Sublessee shall pay to Sublessor a security deposit of Eight Thousand Three Hundred Six and 16/100 Dollars ($8,306.16) (the "Deposit") which Deposit shall be held by Sublessor without interest as security for the faithful performance by Sublessee of all of the terms of this Sublease by Sublessee to be observed and performed. If Sublessee defaults and said default is not cured within any applicable cure period under any of the terms of this Sublease, Sublessor may, at its option and without prejudice to any other remedy, apply all or any portion of the Deposit to the loss suffered by Sublessor as a result of such default and Sublessee shall forthwith upon demand restore the Deposit to the original sum deposited. If Sublessee elects to so apply all or any portion of the Deposit as aforesaid, it shall notify Sublessee of such application within a reasonable period of time thereafter. Should Sublessee comply with all of the terms of this Sublease, the Deposit will be returned to Sublessee at the end of the term of this Sublease. 16. Sublessor and Sublessee each represent to the other that no broker was involved in the transaction reflected by this Sublease except Trammel Crow Company, and each of Sublessor and Sublessee agree to indemnify the other party against any loss resulting from breach of this representation. Sublessor shall be responsible for the commission to be paid to Trammel Crow Company in connection with this Sublease in the amount of Six Thousand Five Hundred and Fifty-Seven and 50/100 Dollars ($6,557.50). 17. This Sublease is subject and subordinate to the Prime Lease. Whenever any obligation on the part of Sublessor under this Sublease is, in fact, an obligation to be performed by the Prime Landlord under the Prime Lease, Sublessor's liability herein shall be to use reasonable efforts to obtain performance by such party. If, notwithstanding Sublessor's reasonable efforts, such party shall fail to perform any of its obligations as aforesaid, Sublessee may, in Sublessor's name but at Sublessee's expense, seek to enforce such party's obligations. Sublessor agrees to use reasonable efforts to arrange for Sublessee's name to be added by Prime Landlord to the Tenant directory in the Main Lobby of the 4 Building and at the entranceway door to the Demised Premises. Any reasonable costs associated therewith shall be borne by Sublessor. 18. No oral agreement or prior written matter shall have any force or effect. Sublessee agrees that it is not relying on any representations or agreements other than those contained in this Sublease. This Sublease shall not be modified or cancelled except by a writing executed by Sublessor and Sublessee. 19.
