 AGREEMENT 

NOW, THEREFORE, Landlord and Tenant, in consideration of the mutual promises contained herein and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, agree as follows: 
 1. Definitions. For purposes of this Fourth Amendment, capitalized terms shall have the meanings ascribed to them in the Lease unless otherwise defined herein. The Lease, as amended by this Fourth
Amendment, is referred to herein as the “Amended Lease.” 
 2. Lease of Basement Storage Premises.
Effective on Basement Storage Premises Commencement Date (defined below), Landlord hereby leases to Tenant and Tenant hereby leases from Landlord, the Basement Storage Premises for use by Tenant in accordance with the Permitted Use for the Storage
Rooms portion of the Premises (defined in the Original Lease) and other terms and conditions of the Amended Lease. From and after the Basement Storage Premises Commencement Date, the “Premises” as defined in the Amended Lease, shall
include the Basement Storage Premises. 
 3. Possession and Term. 

(a) Landlord shall use commercially reasonable efforts to tender possession of the Basement Storage Premises to Tenant on August 1,
2012 (the “Estimated Basement Storage Premises Commencement Date”), with the work required of Landlord described on Exhibit B (the “Landlord Work”) Substantially Complete (as defined in the Original
Lease). Tenant agrees that in the event such work is not Substantially Complete on or before the Estimated Basement Storage Premises Commencement Date for any reason, then (a) the Amended Lease shall not be void or voidable, (b) Landlord
shall not be liable to Tenant for any loss or damage resulting therefrom and (c) Tenant shall not be responsible for the payment of any Basic Annual Rent until the actual Basement Storage Premises Commencement Date as described in
Section 3(b) occurs. Notwithstanding anything in the Amended Lease to the contrary, Landlord’s obligation to timely achieve Substantial Completion shall be subject to extension on a day-for-day basis as a result of Force Majeure (as
defined in the Original Lease). 
 (b) The “Basement Storage Premises Commencement Date” shall be the later of
(i) the Estimated Basement Storage Premises Commencement Date and (ii) the day Landlord tenders possession of the Basement Storage Premises to Tenant with the Landlord Work Substantially Complete. If possession is delayed by action of
Tenant, then the Basement Storage Premises Commencement Date shall be the date that the Basement Storage Premises Commencement Date would have occurred but for such delay. Tenant shall execute and deliver to Landlord written acknowledgment of the
actual Basement Storage Premises Commencement Date and the Term Expiration Date within ten (10) days after Tenant takes occupancy of the Basement Storage Premises, in the form attached as Exhibit C hereto. Failure to execute and
deliver such acknowledgment, however, shall not affect the Basement Storage Premises Commencement Date or Landlord’s or Tenant’s liability hereunder. Failure by Tenant to obtain validation by any medical review board or other similar
governmental licensing of the Base Storage Premises required for the Permitted Use by Tenant (if applicable) shall not serve to extend the Basement Storage Premises Commencement Date.

 (c) The Term with respect to the Basement Storage Premises shall expire on the Term
Expiration Date, i.e. August 11, 2016, subject to Tenant’s option to extend granted pursuant to Article 42 of the Original Lease. 
 (d) Landlord and Tenant intend to include the Basement Storage Premises within the definition of “Premises,” but intend that Tenant will occupy the Basement Storage Premises without paying a
share of Operating Expenses allocated to the Basement Storage Premises. As such, the Basement Storage Premises shall be excluded from the Rentable Area (as defined in the Lease) of the Premises for purposes of determining Tenant’s Pro Rata
Share (as defined in the Lease) of the Building, and the numbers and percentages set forth in the chart in Section 4 below have been calculated on that basis. 
 4. Pro Rata Share. The parties hereby acknowledge that when Landlord made a reconciliation measurement of the Original Premises pursuant to the Second Amendment, Landlord also made a reconciliation
measurement of the Building. Accordingly, the parties acknowledge and agree that the Building contains ninety-six thousand one hundred eighty-eight (96,188) square feet of Rentable Area. In addition, the chart set forth in
Section 2.2 of the Original Lease is hereby modified as follows on the dates set forth below: 
  

					
	 As of the Following Dates
	  	 Definition or Provision
	  	 Means the Following

	August 12, 2011	  	Approximate Rentable Area of Premises	  	28,567 square feet

		  	Approximate Rentable Area of the Building	  	96,188 square feet
		  	Approximate Tenant’s Pro Rata Share of Building	  	33.89%
	February 12, 2013	  	Approximate Rentable Area of Premises	  	36,268 square feet
		  	Approximate Rentable Area of the Building	  	96,188 square feet
		  	Approximate Tenant’s Pro Rata Share of Building	  	37.71%

 5. Basement Storage Premises Basic Annual Rent. Commencing on the Basement Storage Premises
Commencement Date, the initial annual Basic Annual Rent per square foot of Rentable Area for the Basement Storage Premises shall be Eighteen and 00/100 Dollars ($18.00). Basic Annual Rent for the Basement Storage Premises shall increase by three
percent (3%) on each annual anniversary of the Basement Storage Premises Commencement Date during the Term.

 6. Condition of Premises. Tenant acknowledges that (a) it is fully familiar with
the condition of the Basement Storage Premises and, notwithstanding anything contained in the Amended Lease to the contrary, agrees to take the same in its condition “as is” as of the Basement Storage Premises Commencement Date, and
(b) Landlord shall have no obligation to alter, repair or otherwise prepare the Basement Storage Premises for Tenant’s occupancy or to pay for any improvements to the Basement Storage Premises, except as may be expressly provided in the
Amended Lease or as part of the Landlord Work. 
 7. Broker. Tenant represents and warrants that it has not dealt with
any broker or agent in the negotiation for or the obtaining of this Fourth Amendment and agrees to indemnify, defend and hold Landlord harmless from any and all cost or liability for compensation claimed by any such broker or agent employed or
engaged by it or claiming to have been employed or engaged by it. 
 8. No Default. Tenant represents, warrants and
covenants that, to the best of Tenant’s knowledge, Landlord and Tenant are not in default of any of their respective obligations under the Lease and no event has occurred that, with the passage of time or the giving of notice (or both) would
constitute a default by either Landlord or Tenant thereunder. 
 9. Effect of Amendment. Except as modified by this
Fourth Amendment, the Lease and all the covenants, agreements, terms, provisions and conditions thereof shall remain in full force and effect and are hereby ratified and affirmed. The covenants, agreements, terms, provisions and conditions contained
in this Fourth Amendment shall bind and inure to the benefit of the parties hereto and their respective successors and, except as otherwise provided in the Lease, their respective assigns. In the event of any conflict between the terms contained in
this Fourth Amendment and the Lease, the terms herein contained shall supersede and control the obligations and liabilities of the parties. From and after the date hereof, the term “Lease” as used in the Lease shall mean the Lease, as
modified by this Fourth Amendment. 
 10. Miscellaneous. This Fourth Amendment becomes effective only upon execution and
delivery hereof by Landlord and Tenant. The captions of the paragraphs and subparagraphs in this Fourth Amendment are inserted and included solely for convenience and shall not be considered or given any effect in construing the provisions hereof.
All exhibits hereto are incorporated herein by reference. Submission of this instrument for examination or signature by Tenant does not constitute a reservation of or option for a lease, and shall not be effective as a lease, lease amendment or
otherwise until execution by and delivery to both Landlord and Tenant. 
 11. Counterparts. This Fourth Amendment may be
executed in one or more counterparts, each of which, when taken together, shall constitute one and the same document.
