2. LIMITATIONS AND OTHER MATTERS

     2.1 The exemption set forth in Section 1 above (the “ Ownership Limit Waiver ”) shall not be effective if and to the extent that, as a result of Vornado’s ownership of Equity Stock of the Company permitted by reason of the Ownership Limit Waiver, (A) the Company would be considered to own (actually or Constructively, applying the provisions of Section 856(d)(5) of the Code) an interest described in Section 856(d)(2)(B) of the Code in a “Vornado Related Tenant” (as defined in Section 2.4 herein), or (B) any “individual” (within the meaning of Section 542(a)(2) of the Code) would be considered to “own” (within the meaning of Section 856(h) of the Code) any of the shares of Equity Stock of the Company covered by the Ownership Limit Waiver, of more than 9.8% (by number of shares or value, whichever is more restrictive) of the total outstanding shares of Equity Stock of the Company (whether or not such ownership causes the Company to be “closely held” under the REIT rules). In addition, if the Ownership Limit Waiver is not effective as a result of the operation of any clause(s) of the preceding sentence, the Equity Stock of the Company that otherwise would be Excess Stock shall be deemed to have been transferred to the Company in accordance with subparagraph (b)(1) of Article IX of the Declaration.

     2.2 For the Ownership Limit Waiver to be effective, Vornado Realty L.P. must execute a counterpart signature page to this Agreement and complete and make the

representations and covenants set forth in the Certificate of Representations and Covenants, the form of which is attached hereto as Exhibit A (the “ Certificate ”), and must deliver such Certificate to the Company. Except as otherwise determined by the Board of Trustees of the Company, the Ownership Limit Waiver shall cease to be effective upon any breach of the representations or covenants set forth herein or in the Certificate. In addition, if the Ownership Limit Waiver ceases to be effective as a result of the operation of the preceding sentence, the shares of Equity Stock of the Company that would otherwise be Excess Stock shall be deemed to have been transferred to the Company in accordance with subparagraph (b)(1) of Article IX of the Declaration.

     2.3 Vornado Realty L.P. shall deliver to the Company, at such times as may reasonably be requested by the Company (it being acknowledged that the Company may reasonably make such request on at least a calendar quarterly basis), a certificate signed by an authorized officer of Vornado Realty L.P. to the effect that Vornado Realty L.P. has complied and expects to continue to comply with its representations and covenants set forth in this Agreement and the Certificate. If so requested by the Company, Vornado will cooperate with the Company in investigating any direct or indirect relationship that Vornado and any Person whose ownership of shares of Equity Stock of the Company would be attributed to Vornado under Section 318(a) of the Code (as modified by Section 856(d)(5) of the Code), may have with the Company’s tenants or “independent contractors” (within the meaning of Section 856(d)(3) of the Code), including but not limited to Vornado’s relationship with Winthrop, for purposes of determining compliance with the provisions of this Ownership Limit Waiver and in updating the Certificate accordingly. However, the Company’s remedies under this Agreement with respect to Vornado Realty L.P.’s representations and covenants set forth in this Agreement and the Certificate shall become effective only if and for the taxable years of the Company during which Vornado requires the exemptions afforded to Vornado under this Agreement (the “ Waiver Period ”).

     2.4 For purposes of this Agreement, “ Vornado Related Tenant ” means any entity (x) in which Vornado owns during the Waiver Period (actually or Constructively, applying the provisions of Section 856(d)(5) of the Code), in the case of a corporation, shares equal to or greater than the “Threshold Percentage” (as defined in Section 2.5 herein) of either the total combined voting power of all classes of stock of such entity entitled to vote or the total value of shares of all classes of stock of such entity or, in the case of an entity that is not a corporation, an interest equal to or greater than the Threshold Percentage in the assets or net profits of such entity (such actual or Constructive ownership equal to or greater than the Threshold Percentage being hereinafter called a “ Related Interest ”), (y) from which the Company is or will be deriving rental income (other than a taxable REIT subsidiary, if the requirements of Section 856(d)(8) of the Code are satisfied) and (z) included in the tenant list (the “ Tenant List ”) attached hereto as Exhibit B (or added to such Tenant List pursuant to the next sentence), unless the Board of Trustees of the Company has determined that the Company derives (and is expected to continue to derive) an amount of gross rental income that is sufficiently small so as not to adversely affect the Company’s ability to qualify as a REIT. The Company may add an entity to the Tenant List from time to time by written notice (which may be made by email with a written confirmation copy to follow within one business day by hand, facsimile or overnight delivery) to Vornado and Vornado shall promptly review any such revisions to the Tenant List (reflecting substitute or additional tenants) at the request of the

Company and recertify its acknowledgment and agreement under this Agreement to such Tenant List within three (3) business days of the date of such written notice, which response may initially be made by email, but shall be followed within two (2) business days thereafter with a hard copy of recertification of the Certificate in Exhibit A with the updated Tenant List attached (the “ Response Period ”), provided, however , that if such notice is delivered at a time when Vornado owns a Related Interest in such entity that would result in the Company’s owning (actually or Constructively) an interest in such entity described in Section 856(d)(2)(B) of the Code, then, subject to the following proviso, such entity shall not be added to the Tenant List so long as Vornado so notifies the Company within the Response Period, which response shall include Vornado’s percentage owned in such entity; provided , further , that if such notice is given at a time when either Vornado’s interest in such entity has a fair market value of less than $1,000,000 or Vornado is engaged in active discussions regarding a potential acquisition of a Related Interest
