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 Amendment, capitalized terms shall have the meanings ascribed to them in the Lease unless otherwise defined herein.  The Lease, as amended by this Amendment, is referred to herein as the “Amended Lease.”
2.Additions to Premises.  Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the following space on the following terms:
2.1.    777-02 Premises.  Conditional upon each Vacating Tenant surrendering its currently occupied portions of the 777-02 Premises to Landlord in accordance with such Vacating Tenant’s lease, and subject to Tenant’s termination options set forth in Section 3 hereof, Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the 777-02 Premises as of the date (the “777-02 Premises Commencement Date”) that Landlord tenders possession of the 777-02 Premises to Tenant in compliance with the terms of the Amended Lease and with the 777-02 Landlord Work (as defined in Section 6.1(a) hereof) substantially complete.  If possession is delayed solely because of a Tenant Delay (as defined Section 6.6), then the 777-02 Premises Commencement Date shall be the date that the 777-02 Premises Commencement Date would have occurred but for such delay.  From and after the 777-02 Premises Commencement Date, the term “Premises” shall include

the 777-02 Premises.  The Term with respect to the 777-02 Premises shall expire on the Term Expiration Date for the New Premises, subject to (a) Tenant’s option to extend the Term of the Lease as provided in Article 44 of the Lease and (b) Tenant’s termination option set forth in Section 3 hereof.  Tenant shall execute and deliver to Landlord written acknowledgment of the actual 777-02 Premises Commencement Date within ten (10) days after Tenant takes occupancy of the 777-02 Premises, in the form attached as Exhibit G hereto.  Failure to execute and deliver such acknowledgment, however, shall not affect the 777-02 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 777-02 Premises required for the Permitted Use by Tenant shall not serve to extend the 777-02 Premises Commencement Date.  In the event any Vacating Tenant has not vacated all or any portion of the 777-02 Premises by June 1, 2013, Tenant may provide written notice to Landlord of its intent to terminate the Amended Lease with respect to all or any portion of the 777-02 Premises (the “777-02 Premises Termination Notice”).  Upon Landlord’s receipt of such notice, Landlord shall have thirty (30) days (the “Cure Period”) to remove all Vacating Tenants from the 777-02 Premises.  If, prior to expiration of the Cure Period, all Vacating Tenants have vacated the 777-02 Premises, then such termination notice shall be void and of no further force or effect and the Amended Lease with respect to the 777-02 Premises shall continue in full force and effect.  If, prior to the expiration of the Cure Period, all Vacating Tenants have not vacated the 777-02 Premises, then the Amended Lease with respect to the portion of the 777-02 Premises identified in the 777-02 Premises Termination Notice shall terminate upon expiration of the Cure Period, except for those provisions that expressly survive the expiration or earlier termination thereof.

From and after the 777 S-Level Corridor Premises Commencement Date, the term “Premises” shall include the 777 S-Level Corridor Premises.  If possession is delayed solely because of a Tenant Delay, then the 777 S-Level Corridor Premises Commencement Date shall be the date that the 777 S-Level Corridor Premises Commencement Date would have occurred but for such delay.  The Term with respect to the 777 S-Level Corridor Premises shall expire on the Term Expiration Date for the New Premises, subject to (a) Tenant’s option to extend the Term of the Lease as provided in Article 44 of the Lease and (b) Tenant’s termination option set forth in Section 3 hereof.  Tenant shall execute and deliver to Landlord written acknowledgment of the actual 777 S-Level Corridor Premises Commencement Date within ten (10) days after Tenant takes occupancy of the 777 S-Level Corridor Premises, in the form attached as Exhibit G hereto.  Failure to execute and deliver such acknowledgment, however, shall not affect the 777 S-Level Corridor 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 777 S-Level Corridor Premises required for the Permitted Use by Tenant shall not serve to extend the 777 S-Level Corridor Premises Commencement Date.

5.Condition of 10th Amendment Expansion Premises.

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:

BMR form dated 2/1/13

1.Definitions.  For purposes of this Amendment, capitalized terms shall have the meanings ascribed to them in the Lease unless otherwise defined herein.  The Lease, as amended by this Amendment, is referred to herein as the “Amended Lease.”
2.777-02 Premises.  Landlord and Tenant acknowledge and agree that (a) Landlord has tendered possession of the 777-02 Premises to Tenant in compliance with all of the terms and conditions of the Amended Lease and with the 777-02 Landlord Work substantially complete and (b) the 777-02 Premises Commencement Date is March 12, 2013.
3.Additional 777-02 Landlord Work.  
(a)     Landlord shall, at Landlord’s sole cost and expense, cause the work described on attached Exhibit A (the “Additional 777-02 Landlord Work”) to be completed in the 777-02 Premises.  Landlord shall commence the Additional 777-02 Landlord Work as soon as reasonably practicable after the Execution Date and shall diligently continue such work until completion (subject to Tenant’s rights pursuant to Section 3(b) below).  Tenant acknowledges that Landlord will be constructing the Additional 777-02 Landlord Work in the 777-02 Premises during Tenant’s occupancy thereof.  Tenant shall permit Landlord to enter the 777-02 Premises at all times (including during business hours) to construct the Additional 777-02 Landlord Work, and Tenant shall otherwise reasonably cooperate with Landlord throughout the construction process to enable Landlord to complete the Additional 777-02 Landlord Work in a timely and efficient manner.  In accessing the 777-02 Premises and constructing the Additional 777-02 Landlord Work, Landlord shall reasonably cooperate with Tenant so as to cause as little interference to Tenant as is reasonably possible; provided, however, that in no event shall Landlord’s construction of the Additional 777-02 Landlord Work in the 777-02 Premises (a) cause Rent to abate under the Amended Lease or (b) constitute a forcible or unlawful entry, a detainer or an eviction of Tenant.  In the event that Tenant fails to comply with any of its obligations under this Section and such failure causes Landlord to incur additional costs with respect to the Additional 777-02 Landlord Work, Tenant shall pay to Landlord as Additional Rent the amount of any such additional costs within thirty (30) days of receiving an invoice from Landlord.
(b)    If Landlord has not completed the Additional 777-02 Landlord Work on or before February 14, 2014, then Tenant may (but is not obligated to) notify Landlord that Tenant intends to complete such Additional 777-02 Landlord Work, which notice shall contain a reference to this Section 3(b) (a “777-02 Self-Help Warning Notice”).  If, five (5) business days after receiving the 777-02 Self-Help Warning Notice, Landlord has still not completed the Additional 777-02 Landlord Work, then notwithstanding anything to the contrary in the Lease (including this Amendment), Tenant may complete such Additional 777-02 Landlord Work (the “777-02 Self-Help Work”) and shall have reasonable access to all portions of the 777 Building necessary to complete such work, provided that:  (a) the 777-02 Self-Help Work shall not adversely affect (even in a de-minimis manner) any other tenant or any Utilities, except to the extent set forth in the plans and drawings for the Additional 777-02 Landlord Work; (b) Tenant shall act in a commercially reasonable manner and diligently endeavor to minimize the cost of the 777-02 Self-Help Work; and (c) Tenant shall complete the 777-02 Self-Help Work (i) in a good and workmanlike manner, (ii) in compliance with Applicable Laws and (iii) in accordance with the plans attached to this Amendment as Exhibit 

2

A.  Notwithstanding the foregoing, Tenant shall not engage in 777-02 Self-Help Work involving building systems that serve both Tenant and any other tenant, except to the extent set forth in the plans and drawings for the Additional 777-02 Landlord Work.  Landlord shall promptly reimburse Tenant (or allow Tenant a credit against Basic Annual Rent) for Tenant’s actual, reasonable, necessary, and reasonably documented cost of any 777-02 Self-Help Work.

4.Termination Option (10th Amendment Swing Space).  Section 3.8 of the Tenth Amendment is hereby deleted in its entirety and replaced with the following:
“3.8    Subject to all of the terms and conditions of this Section 3.8, Tenant shall be entitled to terminate (with no penalty) the Amended Lease with respect to one or both of (a) the 777-02 Premises and (b) the Additional 01 Premises together with the 01 Premises ((a) and (b), collectively, the “10th Amendment Swing Space”); provided, however, that in no event shall any such termination be effective prior to December 31, 2018.   Tenant shall exercise such right, if at all, by providing Landlord with at least nine (9) months’ advance written notice, which notice shall set forth the applicable space being terminated (the “Terminated Space”) and the effective date of such termination (the “Termination Date”).  If, in such notice, Tenant elects to terminate the Amended Lease with respect to only (a) or (b) of the 10th Amendment Swing Space, then Tenant may elect to terminate the Amended Lease with respect to the other portion (and not less than the entire other portion) of the 10th Amendment Swing Space at a later date, in accordance with this Section 3.8.  On or before the applicable Termination Date, Tenant shall surrender the applicable Terminated Space in the condition required under the Amended Lease.  From and after the applicable Termination Date, (x) the Lease shall terminate and be of no further force and effect with respect to the applicable Terminated Space, except for those provisions that expressly survive the expiration or earlier termination thereof, (y) the applicable Terminated Space shall be removed from the Premises and (z) Tenant’s Pro Rata Shares shall be adjusted accordingly.”
5.Deletion of Termination Options.  Notwithstanding anything to the contrary in the Amended Lease, Section 3 of the Ninth Amendment, Section 3.1 of the Tenth Amendment and Section 3.7 of the Tenth Amendment are hereby deleted in their entirety and shall no longer be of any further force or effect.
6.Broker. Tenant represents and warrants that it has not dealt with any broker or agent in the negotiation for or the obtaining of this Amendment, other than Studley Inc. (“Broker”); provided, however, Broker is not entitled to a leasing commission in connection with this Amendment.  Tenant agrees to indemnify, defend and hold Landlord harmless from any and all cost or liability for compensation claimed by any such broker or agent (including Broker) employed or engaged by it or claiming to have been employed or engaged by it in connection with this Amendment.   
7.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.

3

8.Notices.  Tenant confirms that, notwithstanding anything in the Lease to the contrary, notices delivered to Tenant pursuant to the Amended Lease should be sent to:
Regeneron Pharmaceuticals, Inc.
777 Old Saw Mill River Road

The covenants, agreements, terms, provisions and conditions contained in this 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.

The captions of the paragraphs and subparagraphs in this 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 Amendment may be executed in one or more counterparts, each of which, when taken together, shall constitute one and the same document.
