None of the Company's other subsidiaries individually or in the aggregate constitute a "Significant Subsidiary" as defined in Rule 1-02 of Regulation S-X.

2.2 Power, Authority and Enforceability.

(a) The Company has all requisite power and authority, and, prior to the Closing Date, shall have taken all required action necessary, to execute, deliver and perform this Agreement and to issue the Class W Preferred Shares as herein provided.

(b) This Agreement has been duly executed and delivered by the Company and constitutes the legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium, and other laws of general application affecting enforcement of creditors' rights generally, and (ii) laws relating to the availability of specific performance, injunctive relief, or other equitable remedies.

The shares of Common Stock issuable upon the conversion of the Class W Preferred Shares (the "Common Shares") issued hereunder will be duly and validly reserved for such issuance (based upon the initial conversion price thereof) and, when issued upon such conversion in accordance with the Class W Preferred Articles Supplementary, will be duly and validly issued, fully paid and nonassessable and will be issued in compliance with all applicable federal and state securities laws.

2.5 Compliance with Other Instruments.

The execution, delivery and performance of this Agreement by the Company and the Operating Partnership and the consummation by the Company and the Operating Partnership of the transactions contemplated hereby do not (i) result in a violation of the Company's Charter, as amended to date (the "Charter"), or the Company's Amended and Restated Bylaws, as amended to date (the "Bylaws"), (ii) subject to the effectiveness of the amendment referred to in Sections 4.7 and 5.3, result in a violation of the Operating Partnership's Agreement of Limited Partnership, or (iii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which the Company or any of its Subsidiaries is a party, or result in a violation of any law, rule, regulation, order, judgment or decree applicable to the Company, any of its Subsidiaries or by which any property or asset of the Company or any of its Subsidiaries is bound or affected (except for such conflicts, defaults, terminations, amendments, accelerations, cancellations and violations as would not, individually or in the aggregate, have a Material Adverse Effect or impair the Company's ability to perform in all material respects its obligations under this Agreement).

2.6 Exchange Exempt Under the Securities Act.

Assuming the accuracy of the Investor's representation in Section 3.5 hereof, the exchange of the Class W Preferred Shares for the Class O Preferred Shares as contemplated by this Agreement is exempt from registration under the Securities Act in reliance upon Section 3(a)(9) of the Securities Act.
