“Prior to the earliest of (i) the earlier of (x) the Close of Business on November 6, 2016 and (y) the first Business Day following the date on which the Company effects a distribution to its holders of Common Stock of all of the outstanding shares of the Subsidiary of the Company formed to effect the separation of the Company’s real estate into a separate publicly traded company (the “Final Expiration Date”), (ii) the time at which the Rights are redeemed as provided in Section 23 hereof, (iii) the time at which the Rights are exchanged as provided in Section 24 hereof and (iv) immediately prior to the Effective Time of the Merger (but only if the Effective Time shall occur) (the earlier of (i), (ii), (iii) and (iv) being the “Expiration Date”), the registered holder of any Rights Certificate may, subject to the other provisions hereof, including without limitation Sections 7(e), 7(f), 9(c), 11(a) and 23 hereof, exercise the Rights evidenced thereby, in whole or

in part, at any time after the Distribution Date upon surrender of the Rights Certificate, with the form of election to purchase and the certificate on the reverse side thereof duly executed, to the Rights Agent at the office of the Rights Agent designated for such purpose, together with payment of the aggregate Purchase Price for the number of Units of Preferred Stock (or, following a Triggering Event, other securities, cash or other assets, as the case may be) for which such surrendered Rights are then exercisable.”

(i) Section 11(a) of the Agreement is hereby amended and supplemented to add the following Section 11(a)(iv):

“Notwithstanding anything in this Agreement to the contrary, in no event shall any Exempt Event be construed to give any holders of the Rights Certificates (and, prior to the Distribution Date, registered holders of shares of Company Common Stock) or any other Person any legal or equitable rights, remedies or claims under this Agreement.”

2. Governing Law. This Amendment shall be governed by, and construed in accordance with, the laws of the State of Delaware applicable to contracts executed in and to be performed entirely in such State.

3. Counterparts. This Amendment may be executed (including by facsimile and PDF) in counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same instrument.

4. Effectiveness. This Amendment shall be deemed effective as of immediately prior to the execution and delivery of the Merger Agreement. Except as amended hereby, the Agreement shall remain in full force and effect and shall be otherwise unaffected hereby. If for any reason the Merger Agreement is terminated in accordance with its terms, then this Amendment shall become null and void and be of no further force and effect and the Agreement shall remain exactly the same as it existed immediately prior to the execution of this Amendment.

5. Severability. If any term, provision, covenant or restriction of this Amendment is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Amendment shall remain in full force and effect and shall in no way be affected, impaired or invalidated; provided, that notwithstanding anything in this Amendment to the contrary, if any such term, provision, covenant or restriction is held by such court or authority to be invalid, void or unenforceable and the Board of Directors determines in its good faith judgment that severing the invalid language from this Amendment would adversely affect the purpose or effect of this Amendment and the Rights shall not then be redeemable, the right of redemption set forth in Section 23 of the Agreement shall be reinstated and shall not expire until the Close of Business on the tenth Business Day following the date of such determination by the Board of Directors.
