Section 2.2 Purchaser’s Representations and Warranties.

Purchaser represents, warrants and agrees as follows:

(a) Organization and Good Standing. Purchaser is a limited liability company, duly organized, validly existing and in good standing (as applicable) under the laws of the jurisdiction of its organization and has the requisite power and authority to own, lease and operate its properties and to conduct its business.

12

(b) Authorization and Power. Purchaser has the requisite power and authority, corporate or otherwise, to enter into and perform its obligations under this Agreement and the Related Documents, including to subscribe for the Purchased Shares being sold to it hereunder. The execution, delivery and performance of the this Agreement and the Related Documents by Purchaser and the consummation by it of the transactions contemplated hereby and thereby have been duly authorized by all necessary corporate, partnership, limited liability company and/or other action, and no further consent or authorization of Purchaser or its board of directors, other governing body, managers, members, partners or other Person, as the case may be, is required.

(c) No Public Sale or Distribution. Purchaser is subscribing for the Purchased Shares for its own account for investment and not with a view toward, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered or exempted under the Securities Act if permitted by the Related Documents. Purchaser does not presently have any agreement or understanding, directly or indirectly, or any intention to enter such agreement or understanding, with any Person to distribute the Purchased Shares. As of the date hereof, Purchaser is subscribing for the Purchased Shares hereunder in the ordinary course of its business and not with the purpose nor with the effect of changing or influencing the control of the Company, nor in connection with or as a participant in any transaction having such purpose or effect.

(d) Accredited Investor/Qualified Institutional Buyer Status. Purchaser is an “accredited investor” as that term is defined in Rule 501(a) of Regulation D. Purchaser is a partnership or a limited liability company or similar entity not formed for the specific purpose of acquiring the Purchased Shares and has total assets in excess of $5,000,000, or is an entity in which each equity owner is an “accredited investor.”

(e) Reliance on Exemptions. Purchaser understands that the Purchased Shares are being offered and issued to it in reliance on specific exemptions from the registration requirements of U.S. federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and Purchaser’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of Purchaser to subscribe for the Purchased Shares.

(f) Information. Purchaser has evaluated the merits and risks of acquiring the Purchased Shares on the terms set forth in this Agreement on its own and without reliance on the Company or any of its affiliates or representatives (other than with respect to the Company’s express representations and warranties set forth herein). Purchaser and its advisors have been furnished with, or had access to, and have been afforded opportunity to review, all materials relating to the business, finances and operations of the Company, the Operating Partnership and their respective subsidiaries and materials relating to the offer and sale of the Purchased Shares that have been requested by Purchaser as it has deemed necessary or appropriate to conduct its due diligence investigation and has sufficient knowledge and experience in investing in companies similar to the Company so as to be able to evaluate the risks and merits of its investment in the Company. Purchaser and its advisors have been afforded the opportunity to ask questions of, and to receive answers from, the Company. Neither such inquiries nor any other due diligence investigations conducted by Purchaser or its advisors, if any, or its representatives

13

shall modify, amend or affect Purchaser’s right to rely on the Company’s representations and warranties contained herein. Purchaser understands that its investment in the Purchased Shares involves a high degree of risk and Purchaser is able to afford a complete loss of such investment. Purchaser has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Purchased Shares.

(g) No Governmental Review. 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 Purchased Shares or the fairness or suitability of the investment in the Purchased Shares nor have such authorities passed upon or endorsed the merits of the offering of the Purchased Shares.

(h) Transfer or Resale. Purchaser understands that the Purchased Shares are “restricted securities” under applicable U.S. federal securities laws and that the Securities Act and the rules of the Commission provide in substance that Purchaser may dispose of the Purchased Shares only pursuant to an effective registration statement under the Securities Act or an exemption therefrom, and Purchaser understands that, except as provided in the Registration Rights Agreement, the Company has no obligation or intention to register the offer and resale of any of the Purchased Shares, or to take action so as to permit sales pursuant to the Securities Act (including Rule 144 thereunder). Consequently, Purchaser understands that Purchaser may bear the economic risks of the investment in the Purchased Shares for an indefinite period of time.

(i) Legends. Purchaser understands that the certificates or other instruments representing the Purchased Shares, except as set forth below, shall bear any legend as required by the “blue sky” laws of any state or the Company’s Articles of Amendment and Restatement and a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of such share certificates):

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT OF THE ISSUER THAT THESE SECURITIES MAY BE OFFERED, SOLD, OR OTHERWISE TRANSFERRED ONLY (A) TO THE ISSUER, (B) PURSUANT TO REGISTRATION UNDER THE SECURITIES ACT, (C) OUTSIDE THE UNITED STATES PURSUANT TO REGULATION S UNDER THE SECURITIES ACT, (D) INSIDE THE UNITED STATES PURSUANT TO THE EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER, IF AVAILABLE, OR (E) IN A TRANSACTION THAT IS OTHERWISE EXEMPT FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, AND IN EACH CASE IN COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS AND THE APPLICABLE LAWS OF ANY OTHER JURISDICTION, PROVIDED THAT IN THE CASE OF (C), (D) OR (E) ABOVE, THE HOLDER HAS, PRIOR TO SUCH SALE, FURNISHED TO THE ISSUER A LEGAL OPINION OF COUNSEL OF RECOGNIZED STANDING, REASONABLY SATISFACTORY TO THE ISSUER. HEDGING TRANSACTIONS INVOLVING THESE SECURITIES MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH THE SECURITIES ACT.

Subject to the terms of the Stockholders Agreement, the legend set forth above shall be removed and the Company shall issue a certificate without such legend to the holder of the Purchased Shares upon which it is stamped, if, unless otherwise required by state securities laws, (i) such Purchased Shares are registered for resale under the Securities Act; (ii) in connection

14

with a sale, assignment or other transfer, such holder provides the Company with an opinion of a law firm reasonably acceptable to the Company, in a form reasonably acceptable to the Company, to the effect that such sale, assignment or transfer of the Purchased Shares may be made without registration under the applicable requirements of the Securities Act; or (iii) such holder provides the Company with reasonable assurance that the Purchased Shares can be sold, assigned or transferred pursuant to Rule 144.

(j) Validity; Enforcement. This Agreement and each of the Related Documents has been duly and validly authorized, executed and delivered on behalf of Purchaser and shall constitute the legal, valid and binding obligations of Purchaser enforceable against Purchaser in accordance with its respective terms, except as such enforceability may be limited by general principles of equity or to applicable bankruptcy, insolvency, reorganization, moratorium, liquidation and other similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies.

(k) No Conflicts. The execution, delivery and performance by Purchaser of this Agreement and the Related Documents and the consummation by Purchaser of the transactions contemplated hereby and thereby will not (i) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of Purchaser pursuant to, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which Purchaser is a party or by which Purchaser is bound or to which any of the property or assets of Purchaser is subject; (ii) result in any violation of the organizational documents of Purchaser; or (iii) result in the violation of any law or statute or any judgment, order, rule or regulation of any court or arbitrator or governmental or regulatory authority, except, in the case of clause (i) above, for any such conflict, breach, violation or default that would not, individually or in the aggregate, have a material adverse effect on the ability of Purchaser to perform its obligations hereunder.

(l) No General Solicitation. Purchaser acknowledges that the Purchased Shares were not offered to Purchaser by means of any form of general or public solicitation or general advertising, or publicly disseminated advertisements or sales literature, including (i) any advertisement, article, notice or other communication published in any newspaper, magazine, website, or similar media, or broadcast over television or radio; or (ii) any seminar or meeting to which Purchaser was invited by any of the foregoing means of communications.

(m) Brokers. Neither Purchaser nor its affiliates have employed the services of, or dealt with, any broker, agent or finder in connection with the transactions contemplated hereby, except that the parties acknowledge that CBRE introduced the parties at the outset of negotiations for the transactions contemplated hereby and shall be paid a commission by the Company in connection therewith.

The Company may require additional information from Purchaser or Purchaser’s beneficial owners to satisfy its due diligence obligations under the Bad Actor Rule.

(q) Tax Matters. Purchaser either (i) is treated as an integral part of a foreign sovereign within the meaning of Section 892 of the Code and the Treasury Regulations promulgated thereunder; or (ii) is wholly owned, directly or indirectly, by one or more integral parts of a foreign sovereign within the meaning of Section 892 of the Code and the Treasury Regulations promulgated thereunder.

ARTICLE 5

SURVIVAL; INDEMNIFICATION

Section 5.1 Survival; Indemnification.

(a) The respective representations and warranties of the Company and Purchaser contained in Section 2.1 and Section 2.2 shall survive for a period of twelve (12) months from the Closing; provided, however, that the representations and warranties contained in Section 2.1(o) shall survive for a period of twenty-four (24) months from the Closing (the “Survival Period”). The parties agree that no claim may be brought based upon, directly or indirectly, any of the representations and warranties contained in this Agreement after the Survival Period. The termination of the representations and warranties provided herein shall not affect a party in respect of any good faith claim made by such party in reasonable detail in writing received by the other party prior to the expiration of the Survival Period.

(b) From and after the Closing, the Company shall indemnify, save and hold harmless Purchaser from and against any and all costs, losses, liabilities, obligations, damages, claims, judgments, awards, and expenses (whether or not arising out of third-party claims), including interest, penalties, reasonable attorneys’ fees and any amounts paid in settlement of the foregoing (collectively, “Losses”) incurred in connection with, arising out of, or resulting from (i) any breach of any representation or warranty made by the Company in Section 2.1 hereof or in the certificate delivered pursuant to Section 3.2(e); or (ii) any breach of any covenant or agreement to be performed by the Company in this Agreement.

(c) From and after the Closing, Purchaser shall indemnify, save and hold harmless the Company from and against any and all Losses incurred in connection with, arising out of, or resulting from (i) any breach of any representation or warranty made by Purchaser in Section 2.2 hereof or in the certificate delivered pursuant to Section 3.3(d); or (ii) any breach of any covenant or agreement to be performed by Purchaser in this Agreement.

(d) Each party entitled to indemnification under this Section 5.1 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party (at its expense) to assume the defense of any such claim or any litigation resulting therefrom; provided, that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld, conditioned or delayed), and the Indemnified Party may participate in such defense at such Indemnified Party’s expense; and provided, further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under

21

this Agreement, unless such failure is actually materially and adversely prejudicial to the Indemnifying Party in defending such claim or litigation and in such case, only to the extent of such prejudice. Notwithstanding the foregoing, an Indemnified Party shall have the right to retain its own counsel, with the reasonable fees and expenses of no more than one such counsel (at standard rates not in excess of those paid by the Indemnified Party in the ordinary course of its business) to be paid by the Indemnifying Party, if (i) the Indemnifying Party shall have failed, or is not entitled to assume, the defense of such claim in accordance with this Section 5.1(d); (ii) the employment of such counsel has been specifically authorized in writing by the Indemnifying Party; or (iii) representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential differing interests between such Indemnified Party and any other party represented by such counsel in such proceeding.

(e) An Indemnified Party shall use commercially reasonable efforts to mitigate any Losses which form the basis of an indemnification claim under this Section 5.1; provided, however, that such commercially reasonable efforts shall not require any Indemnified Party to commence any litigation, make any material monetary expenditure, or offer or grant any material accommodation (financial or otherwise) to any third party. Under no circumstances shall any Losses include consequential, indirect, punitive or other similar damages, including diminution of value, lost profits, lost revenues, business interruptions, or loss of business opportunity or reputation. Losses shall be calculated only to the extent attributable to the transactions contemplated by this Agreement (and, for the avoidance of doubt, shall not include any Losses to the extent attributable to or arising under any other agreements or arrangements, including but not limited to joint ventures, between the Company and its subsidiaries, on the one hand, and Purchaser and its subsidiaries, on the other hand). The amount of any Losses for which indemnification is provided under this Section 5.1 shall be net of any amounts actually recovered by the Indemnified Party from third parties, including under insurance policies with respect to such Losses (which the Indemnified Party shall use commercially reasonable efforts to recover), and shall be reduced to take account of any net tax benefit actually realized by the Indemnified Party in the form of a reduction of the cash taxes actually payable in the year the indemnity payment is made or a prior year to the extent such reduction arises from the incurrence or payment of any such Losses.

(f) An Indemnifying Party shall not be liable for any settlement of a claim effected without its written consent (which consent will not be unreasonably withheld, conditioned or delayed). No Indemnifying Party, in its defense of any such claim, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which (i) does not include as an unconditional term thereof the giving by the claimant or plaintiff to such claim a release to the Indemnified Party from all liability with respect to such claim; and (ii) is not entirely indemnifiable by the Indemnifying Party pursuant to this Article 5, and imposes any injunctive relief or other restrictions of any kind or nature on any Indemnified Party.

(g) Unless otherwise required by law, the Company and Purchaser agree to treat any indemnity payment made pursuant to this Article 5 as an adjustment to the Purchase Price for U.S. federal, state, local and non-U.S. Tax purposes.
