Section 3. Representations and Warranties of the Purchaser.

B. Authorization; No Breach.

(ii) The Purchaser is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D.

-3-

(iii) The Purchaser understands that the offer and sale of the Preferred Shares to the Purchaser has not been, and will not be, registered under the Securities Act by reason of a specific exemption from the registration provisions of the Securities Act that depends upon, among other things, the bona fide nature of the investment intent and the accuracy of the Purchaser’s representations as expressed herein. The Purchaser understands that the Preferred Shares are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, the Purchaser must hold the Preferred Shares indefinitely unless they are registered with the Commission and qualified by state authorities, or an exemption from such registration and qualification requirements is available. The Purchaser further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Preferred Shares, and on requirements relating to the Company which are outside of the Purchaser’s control, and which the Company is under no obligation and may not be able to satisfy. The Purchaser understands that the offering of the Preferred Shares is not and is not intended to be part of the Offering, and that the Purchaser will not be able to rely on the protection of Section 11 of the Securities Act.

(iv) The Purchaser did not purchase the Preferred Shares as a result of any general solicitation or general advertising within the meaning of Rule 502(c) under the Securities Act.

(v) The Purchaser has been furnished with all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Preferred Shares, which have been requested by the Purchaser. The Purchaser has been afforded the opportunity to ask questions of the executive officers and trustees of the Company. The Purchaser understands that its investment in the Preferred Shares involves a high degree of risk and it has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to the acquisition of the Preferred Shares.

(vi) The Purchaser understands that no U.S. federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Preferred Shares or the fairness or suitability of the investment in the Preferred Shares by the Purchaser nor have such authorities passed upon or endorsed the merits of the offering of the Preferred Shares.

(vii) The Purchaser has such knowledge and experience in financial and business matters, is capable of evaluating the merits and risks of an investment in the Preferred Shares and is able to bear the economic risk of an investment in the Preferred Shares in the amount contemplated under this Agreement for an indefinite period of time. The Purchaser has adequate means of providing for its current financial needs and contingencies and will have no current or anticipated future needs for liquidity which would be jeopardized by the investment in the Preferred Shares. The Purchaser can afford a complete loss of its investments in the Preferred Shares.

-7-

E. Successors and Assigns.

J. Descriptive Headings; Interpretation. The descriptive headings of this Agreement are inserted for convenience only and do not constitute a substantive part of this Agreement. The words “include,” “includes” and “including” will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular section unless expressly so limited. The parties hereto intend that each representation, warranty and covenant contained herein will have independent significance. If

-8-

any party hereto has breached any representation, warranty or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party hereto is in breach of the first representation, warranty or covenant.

K. Governing Law. This Agreement and the rights and obligations of the parties hereunder shall be construed in accordance with and governed by the laws of New York applicable to contracts wholly performed within the borders of such state, without giving effect to the conflict of law principles thereof. The parties hereto irrevocably submit to the exclusive jurisdiction of any federal court sitting in the Southern District of New York or any state court located in New York County, State of New York, over any suit, action or proceeding arising out of or relating to this Agreement. To the fullest extent they may effectively do so under applicable law, the parties hereto irrevocably waive and agree not to assert, by way of motion, as a defense or otherwise, any claim that they are not subject to the jurisdiction of any such court, any objection that they may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.
