The Company shall be entitled to postpone (but not more than twice in any 12-month period), for a reasonable period of time not in excess of 45 days, the filing or initial effectiveness of such Prospectus or supplement thereto, or suspend the use of the Registration Statement (or a Prospectus thereunder), if the Company delivers to the Holders a certificate signed by both the Chief Executive Officer and Chief Financial Officer of the Company certifying that, in the good faith judgment of the Board of Directors of the Company, such registration, offering or use would reasonably be expected to materially adversely affect or materially interfere with any bona fide material financing of the Company or any material transaction under consideration by the Company or would require the disclosure of information that has not been, and is not otherwise required to be, disclosed to the public, the premature disclosure of which would materially adversely affect the Company. Such certificate shall contain a statement of the reasons for such postponement or suspension and an approximation of the anticipated delay.

Section 2.02 Underwritten Shelf Take-Down; Selection of Underwriters. Subject to the terms and conditions of this Agreement, the Company shall conduct an underwritten resale of Registrable Shares (an “Underwritten Shelf Take-Down”) upon the written request of one or more Holders of Registrable Shares. In connection with any proposed Underwritten Shelf Take-Down, each Holder participating in such Underwritten Shelf Take-Down agrees, in an effort to conduct any such Underwritten Shelf Take-Down in the most efficient and organized manner, to coordinate reasonably with the other Holders prior to initiating any sales efforts and cooperate reasonably with the other Holders as to the terms of such Underwritten Shelf Take-Down, including, without limitation, the aggregate amount of Registrable Shares to be sold and the number of Registrable Shares to be sold by each Holder in the Underwritten Shelf Take-Down.

If requested by the sole or lead managing Underwriter for any Underwritten Shelf Take-Down, the Company shall enter into a customary underwriting agreement with the Underwriters for such offering, such agreement to be reasonably satisfactory in substance and form to the Company and to the Holders of a majority of the Registrable Shares participating in such Underwritten Shelf Take-Down and to contain such representations and warranties by the Company and such other terms as are customary in agreements of that type, including, without limitation, indemnification and contribution to the effect and to the extent provided in Section 4.01.

(b) Holders to be Party to Underwriting Agreement. The Holders participating in an Underwritten Shelf Take-Down shall be party to the underwriting agreement between the Company and such Underwriters and may, at the option of the Holders of a majority of the Registrable Shares participating in such Underwritten Shelf Take-Down, require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such Underwriters shall also be made to and for the benefit of such Holders and that any or all of the conditions precedent to the obligations of such Underwriters under such underwriting agreement be conditions precedent to the obligations of such Holders; provided, however, that the Company shall not be required to make any representations or warranties with respect to written information provided by such Holders for inclusion in the Registration Statement pursuant to Section 3.01(r). No such Holder shall be required to make any representations or warranties to, or agreements with, the Company or the Underwriters other than representations, warranties or agreements regarding such Holder, such Holder’s Registrable Shares and such Holder’s intended method of disposition.

(c) Participation in Underwritten Registration. Notwithstanding anything herein to the contrary, no Holder may participate in any Underwritten Shelf Take-Down hereunder unless such Holder (i) agrees to sell its securities on the terms and conditions provided in any underwriting agreement pertaining to such Underwritten Shelf Take-Down approved by the Persons entitled hereunder to approve such arrangement and (ii) accurately completes and executes in a timely manner all questionnaires, powers of attorney, custody agreements, lock-up agreements, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.

Section 2.05 Additional Rights.

(a) The Company may grant to Persons other than the Holders the right to request or require the Company to register any Common Stock, or any securities convertible, exchangeable or exercisable for or into Common Stock (“Piggyback Registration Rights”), in connection with any Underwritten Shelf Take-Down; provided, however, that if the sole or lead managing Underwriter of an Underwritten Shelf Take-Down advises the Company and the Holders in writing that in its reasonable and good faith opinion the number of shares of Common Stock proposed to be included in such registration, including all Registrable Shares and all other shares of Common Stock proposed to be included in such underwritten offering, exceeds the number of shares of

5

Common Stock which can be sold in such offering and/or that the number of shares of Common Stock proposed to be included in any such registration would adversely affect the price per share of the Common Stock to be sold in such offering, the Company shall include in such registration (i) first, the shares of Common Stock requested to be included therein by the Holders of Registrable Shares, allocated pro rata among all such holders on the basis of the number of Registrable Shares owned by each such holder or in such manner as they may otherwise agree; and (ii) then, to the extent there is still excess availability, the shares of Common Stock requested to be included therein by holders of Common Stock other than Holders of Registrable Shares, allocated among such holders in such manner as they may agree.

(b) In the event that the Company grants Piggyback Registration Rights to any Person other than the Holders in connection with any public offering of Common Stock by the Company, the Company will also grant such Piggyback Registration Rights to the Holders of Registrable Shares subject to this Agreement.

INDEMNIFICATION AND CONTRIBUTION

Section 4.01 Indemnification by the Company. The Company agrees to indemnify and hold harmless, to the fullest extent permitted by applicable law, each Holder and its Affiliates and their respective officers, directors, managers, partners, equityholders, members, employees, agents and representatives and each Person (if any) which controls a Holder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages, liabilities, costs and expenses (including reasonable attorneys’ fees) (collectively, “Losses”) caused by, arising out of, resulting from or related to any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement, preliminary Prospectus or Prospectus relating to the Registrable Shares (as amended or supplemented from time to time), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the case of the Prospectus, in light of the circumstances under which they were made, not misleading, except insofar as such Losses are caused by or contained in or based upon any information furnished in writing to the Company by or on behalf such Holder or any Underwriter expressly for use therein (which was not subsequently corrected in writing prior to or concurrently with the sale of Registrable Shares to the Person asserting the Loss in sufficient time to permit the Company to amend or supplement the Registration Statement or such Prospectus appropriately) or by the Holder’s failure to deliver a copy of the Registration Statement or Prospectus or any amendments or supplements thereto after the Company has furnished the Holder with copies of the same. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of a Holder or any other Indemnified Party and shall survive the transfer of Registrable Shares by any such Holder in accordance with Section 5.08.

Section 4.02 Indemnification by Holders. Each Holder, severally and not jointly, agrees to indemnify and hold harmless, to the fullest extent permitted by applicable law, the Company and its Affiliates and their respective officers, directors, partners, stockholders, members, employees, agents and representatives and each Person (if any) which controls the Company

10

within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all Losses caused by, arising out of, resulting from or related to any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement, preliminary Prospectus or Prospectus relating to the Registrable Shares (as amended or supplemented from time to time), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the case of the Prospectus, in light of the circumstances under which they were made, not misleading, but only insofar as such Losses are caused by or contained in or based upon any information furnished in writing to the Company by or on behalf of such Holder expressly for use therein (which was not subsequently corrected in writing prior to or concurrently with the sale of Registrable Shares to the Person asserting the Loss in sufficient time to permit the Company to amend or supplement the Registration Statement or such Prospectus appropriately).

Section 4.03 Conduct of Indemnification Proceedings. In case any claim or proceeding (including any governmental investigation) shall be instituted or threatened involving any Person in respect of which indemnity may be sought pursuant to Section 4.01 or Section 4.02, such Person (the “Indemnified Party”) shall promptly notify the Person against which such indemnity may be sought (the “Indemnifying Party”) in writing (it being understood that the failure to give such notice shall not relieve any Indemnifying Party from any liability which it may have hereunder except to the extent the Indemnifying Party is actually and materially prejudiced by such failure) and the Indemnifying Party, upon the request of the Indemnified Party, shall retain counsel reasonably satisfactory to such Indemnified Party to represent such Indemnified Party and shall pay the fees and disbursements of such counsel related to such claim or proceeding. If the Indemnifying Party does not elect within 15 days after receipt of the notice required hereby to assume the defense of any claim or proceeding, the Indemnified Party may assume such defense with counsel of its choice at the cost and expense of the Indemnifying Party. In any such claim or proceeding where the Indemnifying Party has assumed the defense, any Indemnified Party shall have the right to retain its own counsel and participate in, but not control, the defense, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the Indemnified Party and the Indemnifying Party and, in the written opinion of counsel for the Indemnified Party, representation of both parties by the same counsel would be inappropriate due to actual or potential conflicting interests between them, in which case the Indemnified Party may retain counsel of its choice, which counsel shall be reasonably satisfactory to the Indemnifying Party, and such counsel may defend the Indemnified Party and its reasonable fees and expenses shall be paid by the Indemnifying Party. It is understood that the Indemnifying Party shall not, in connection with any claim or proceeding or related proceedings, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel for each such jurisdiction) at any time for all such Indemnified Parties, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Indemnified Parties, such firm shall be designated in writing by the Indemnified Parties. The Indemnifying Party shall not settle any claim or proceeding without the written consent of the Indemnified Party (not to be unreasonably withheld), unless such settlement (x) requires no remedy, relief or penalty other than the payment of money damages which is to be paid in full by the Indemnifying Party, (y) does not require any Indemnified Party to admit culpability or fault in any respect and (z) contains a full and complete

11

release of the Indemnified Party with respect to all matters arising from the facts giving rise to the underlying claim or proceeding. The Indemnifying Party shall not be liable for any settlement of any claim or proceeding effected without its written consent, but if settled with such consent, or if there be a final judgment for the plaintiff, the Indemnifying Party shall indemnify and hold harmless such Indemnified Parties from and against any Loss (to the extent stated above) by reason of such settlement or judgment.

Section 4.04 Contribution. If the indemnification provided for in this Article IV is unavailable to an Indemnified Party in respect of any Losses in respect of which indemnity is to be provided hereunder, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall to the fullest extent permitted by law contribute to the amount paid or payable by such Indemnified Party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of such party in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations; provided, that the maximum amount of liability in respect of such contribution shall be limited, in the case of each Holder, to an amount equal to the net proceeds (after underwriting fees, commissions or discounts) actually received by such Holder from the sale of Registrable Shares effected pursuant to registration as provided hereunder. The relative fault of the Company and each Holder shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and each Holder agree that it would not be just and equitable if contribution pursuant to this Section 4.04 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Party as a result of the Losses referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim or proceeding. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person which was not guilty of such fraudulent misrepresentation.

ARTICLE V.

Any such amendment or waiver shall be binding on all Holders and their respective legal representatives, successors and permitted assigns.

Section 5.05 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one and the same instrument.

Section 5.07 Controlling Law; Jurisdiction and Venue. This Agreement shall be governed by, interpreted under, and construed and enforced in accordance with, the law of the State of Delaware, not taking into account any rules of conflicts laws that would cause the application of the laws of any other jurisdiction.

Agreement or the transactions contemplated hereby. Each of the parties agrees not to commence any action, suit or proceeding relating thereto except in the courts described above in Delaware, other than actions in any court of competent jurisdiction to enforce any judgment, decree or award rendered by any such court in Delaware as described herein. Each of the parties further agrees that notice as provided herein shall constitute sufficient service of process and the parties further waive any argument that such service is insufficient. Each of the parties hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any action or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby, (a) any claim that it is not personally subject to the jurisdiction of the courts in Delaware as described herein for any reason, (b) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (c) that (i) the suit, action or proceeding in any such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

Section 5.08 Assignment of Registration Rights. Each Holder of Registrable Shares may assign all or any part of its rights under this Agreement to any Person to which such Holder sells, transfers or assigns (i) any of its Common OP Units and/or Series H Preferred Units, or (ii) Registrable Shares after such Common OP Units and/or Series H Preferred Units are exchanged into Registrable Shares, in each case provided that (x) such sale, transfer or assignment is permitted under the terms of Company’s charter and the Partnership Agreement, as applicable, any lockup agreements and all other documents and agreements applicable to such securities, and (y) such Person agrees in writing to be bound by the provisions of this Agreement by executing and delivering a joinder agreement in the form of Exhibit B hereto. In the event that the Holder shall assign its rights pursuant to this Agreement in connection with the transfer of less than all its Registrable Shares, including any Registrable Shares issued upon conversion or exchange of its Common OP Units or Series H Preferred Units, the Holder shall also retain its rights with respect to its remaining Registrable Shares, including any Registrable Shares issued upon conversion or exchange of such Common OP Units or Series H Preferred Units.

Section 5.09 Specific Performance. The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with its specific terms or was otherwise breached. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of competent jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity. Additionally, each Party irrevocably waives any defenses based on adequacy of any other remedy, whether at law or in equity, that might be asserted as a bar to the remedy of specific performance of any of the terms or provisions hereof or injunctive relief in any action brought therefor.

Section 5.10 Severability. If any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable, or void, portions of such provision, or such provision in its entirety, to the extent necessary, shall be severed from this Agreement and the balance of this Agreement shall be enforceable in accordance with its terms; provided, that upon any such declaration by a court of competent jurisdiction, the Parties shall
