as of December 19, 2012 (the “Fourth Amendment to Sublease”), a copy of which is attached hereto as Exhibit A. The Original Sublease, as amended by the Fourth Amendment to Sublease, is hereinafter referred to as the
“Sublease”. 
 D. Tenant desires to obtain Landlord’s consent to the Fourth Amendment to Sublease.

 NOW, THEREFORE, in consideration of the foregoing and the agreements contained herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord hereby consents to the amendment of the Original Sublease, as more particularly described in and pursuant to the provisions of the Fourth Amendment to Sublease,
such consent being subject to and upon the following terms and conditions to which Tenant and Sublessee hereby agree: 
  

	1.	All initially capitalized terms not otherwise defined in this Consent shall have the meanings set forth in the Lease unless the context clearly indicates otherwise.



  
 4 









	2.	This Consent to Fourth Amendment shall not be effective and the Fourth Amendment to Sublease shall not be valid unless and until Landlord shall have received:
(a) a fully executed copy of the Fourth Amendment to Sublease, and (b) a fully executed counterpart of this Consent to Fourth Amendment. Tenant and Sublessee each represent and warrant to Landlord that the copy of the Fourth Amendment to
Sublease attached hereto as Exhibit A is true, correct and complete in all material respects. 

  

	3.	Landlord neither approves nor disapproves the terms, conditions and agreements contained in the Fourth Amendment to Sublease, all of which shall be subordinate and at
all times subject to: (a) all of the covenants, agreements, terms, provisions and conditions contained in the Lease, (b) superior ground leases, mortgages, deeds of trust, or any other hypothecation or security now existing or hereafter
placed upon the real property of which the Premises are a part and to any and all advances secured thereby and to all renewals, modifications, consolidations, replacements and extensions thereof, and (c) all matters of record affecting the
Premises and all laws, ordinances and regulations now or hereafter affecting the Premises. 

  

	4.	Nothing contained herein or in the Fourth Amendment to Sublease shall be construed to: 


 

	 	a.	modify, waive, impair, or affect any of the terms, covenants or conditions contained in the Lease (including Tenant’s obligation to obtain any required consents
for any other or future sublettings), or to waive any breach thereof, or any rights or remedies of Landlord under the Lease against any person, firm, association or corporation liable for the performance thereof, or to enlarge or increase
Landlord’s obligations or liabilities under the Lease (including, without limitation, any liability to Sublessee for any portion of the security deposit held by Tenant under the Sublease), and all terms, covenants and conditions of the Lease
are hereby declared by each of Landlord and Tenant to be in full force and effect; or 

  

	 	b.	require Landlord to accept any payments from Sublessee on behalf of Tenant, except as expressly provided for in the Consent. 


Tenant shall remain liable and responsible for the due keeping, performance and observance of all the terms, covenants and conditions set

limitation, the Subleased Premises. 
  

	5.	Notwithstanding anything in the Sublease to the contrary: 

  

	 	a.	Tenant and Sublessee agree to each of the terms and conditions of the Consent, and upon any conflict between the terms of the Sublease and the Consent, the terms of the
Consent shall control. 

  

	 	b.	Notwithstanding anything in the Lease, Tenant agrees to reimburse all of Landlord’s costs and expenses in connection with this Consent to Fourth Amendment in an

or which would affect Landlord’s status as a real estate investment trust. Any further modification or amendment of the Sublease without Landlord’s prior written consent shall be void and of no force or effect. Except as herein amended,
the Original Consent shall remain in full force and effect in accordance with its terms. 

  

	7.	The Consent may not be changed orally, but only by an agreement in writing signed by Landlord and the party against whom enforcement of any change is sought.


  

	8.	This Consent To Fourth Amendment may be executed in any number of counterparts, each of which shall be deemed an original, but all of which when taken together shall
constitute but one and the same instrument. 

  

	9.	The Consent and the legal relations between the parties hereto shall be governed by and construed and enforced in accordance with the internal laws of the State in
which the Premises are located, without regard to its principles of conflicts of law.
