D.Sublandlord and Subtenant desire to amend the Sublease to provide for, among other things, a reduction in the area of the Existing Subleased Premises and the elimination of any expansion options, upon the terms and conditions herein set forth.

3.References to Subleased Premises. Except as expressly set forth herein to the contrary, from and after March 1, 2012, all references in the Sublease and this Third Amendment to the “Subleased Premises” shall be deemed to mean the area depicted on Exhibit B - Third Amended attached hereto and

shall specifically exclude the Third Amendment Contraction Space.

6.Net Rent. Effective as of March 1, 2012, (i) Exhibit E-Second Amended attached to the First Amendment shall be deleted in its entirety and Exhibit E-Third Amended attached hereto shall be substituted therefor and (ii) Net Rent payable by Subtenant to Sublandlord in respect of the Subleased Premises from and after March 1, 2012 shall be as set forth in Exhibit E-Third Amended.

18.No Offer. Submission of this Third Amendment by Sublandlord to Subtenant is not an offer to enter into this Third Amendment but rather is a solicitation for such an offer from Subtenant. Sublandlord shall not be bound by this Third Amendment until Sublandlord has executed and delivered the same to Subtenant.

23.Time of the Essence. Time is of the essence of this Third Amendment and the Sublease and each provision hereof.

Subtenant represents to Sublandlord that Subtenant has dealt only with Studley, Inc. (“Studley”) as an advisor in connection with the transaction contemplated by this Third Amendment. Each of Sublandlord and Subtenant represent that it has not dealt with any broker, agent or finder in connection with this Third Amendment other than JLL and Studley, and that insofar as each party knows, no brokers other than JLL and Studley have participated in the procurement of Subtenant or in the negotiation of this Third Amendment or are entitled to any commission in connection therewith.

IN WITNESS WHEREOF, Sublandlord and Subtenant have executed this Third Amendment to Sublease as of the date and year first above written.
