A registration requested pursuant to this Section 2.1 shall not be deemed to have been effected (i) unless a registration statement with respect thereto has been declared effective by the Commission or (ii) if after it has become effective, such registration is interfered with by any stop order, injunction or other order or requirement of the Commission or other governmental agency or court for any reason and has not thereafter become effective. 2.1.6 Limitations on Registration on Demand. (i) In no event shall the Trust be required to effect more than one registration pursuant to this Section 2.1. (ii) Notwithstanding anything herein, if the Trust reasonably believes that the filing of a registration statement with the Commission would adversely affect the contemplated activities of the Trust, then the Trust may postpone the filing of the applicable registration statement for a period not in excess of 30 days or, in the event the filing is being postponed in connection with a proposed underwritten public offering of the Trust's -3- securities, for such longer period (not to exceed an additional 30 days) as may be reasonably requested by the managing underwriter for such proposed offering. (iii) Notwithstanding anything herein, if the filing of a registration statement pursuant to a Demand would require the Trust to include in a filing with the Commission financial statements of probable or completed acquisitions in order that such registration statement be in compliance with rules and regulations of the Commission, then the Trust may delay the filing of such registration statement until it has included the requisite financial statements (including any necessary pro forma financial information) in a filing with the Commission. 2.2 Registration Procedures. 2.2.1 In connection with the registration of any Registrable Securities under the Securities Act as provided in Section 2.1, the Trust shall as promptly as practicable: (i) prepare and file with the Commission the requisite registration statement to effect such registration and thereafter use commercially reasonable efforts to cause such registration statement to become and remain effective; (ii) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective and to comply with provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such registration statement until all of such Registrable Securities have been sold thereunder; (iii) furnish to the LLC such number of conformed copies of such registration statement and of each such amendment and supplement thereto (in each case including all exhibits), such number of copies of the prospectus contained in such registration statement (including each preliminary prospectus and any summary prospectus) and any other prospectus filed under Rule 424 under the Securities Act, in conformity with the requirements of the Securities Act, and such number of copies of such other documents as the LLC may reasonably request; (iv) use commercially reasonable efforts (x) to register or qualify all Registrable Securities under such other securities or Blue Sky laws of such States of the United States of America where an exemption is not available and as the LLC shall reasonably request, (y) to keep such registration or qualification in effect for so long as such registration statement remains in effect, and (z) to take any other action which may reasonably be necessary or advisable to enable the LLC to consummate the disposition in such jurisdictions of the Registrable Securities to be sold by the LLC, except that the Trust shall not for any such purpose be required to qualify generally to do business as a foreign trust in any jurisdiction wherein it would not, but -4- for the requirements of this paragraph (iv), be obligated to be so qualified or to consent to general service of process in any such jurisdiction; (v) notify the LLC upon discovery that, or upon the happening of any event as a result of which, the prospectus included in the registration statement filed pursuant to a Demand, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading, in the light of the circumstances under which they were made, and at the request of the LLC, use its best efforts to promptly prepare and furnish to the LLC such number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such securities, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; (vi) use commercially reasonable efforts to list all Registrable Securities covered by such registration statement on any national securities exchange or over-the-counter market, if any, on which Registrable Securities covered by such registration statement are then listed. The LLC agrees that upon receipt of any notice from the Trust of the happening of an event of the kind described in Section 2.2.1(v), the LLC shall forthwith discontinue its disposition of Registrable Securities pursuant to the registration statement relating to such Registrable Securities until the LLC's receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.2.1(v). 2.3. Holdback Agreements; Information Blackout. 2.3.1 Holdback Agreements. In connection with an underwritten public offering of securities of the Trust, the LLC agrees that, if required by the underwriter or underwriters, it will not effect any public sale or distribution, including any sale pursuant to Rule 144 under the Securities Act, of any Registrable Securities, during the period commencing 10 days prior to the expected commencement of the offering and ending 30 days after the closing of such offering. 2.3.2 Information Blackout. At any time when a registration statement effected pursuant to this Section 2 relating to Registrable Securities is effective, upon written notice from the Trust to the LLC that the Trust has determined in good faith that sale of Registrable Securities pursuant to the registration statement would require disclosure by the Trust of non-public material information not otherwise required, in the judgment of the Trust, to be disclosed under applicable law, the LLC shall suspend sales of Registrable Securities pursuant to such registration statement until the earlier of (a) 30 days after the Trust makes such good faith determination and (b) such time as the Trust notifies the LLC that such material information has -5- been disclosed to the public or has ceased to be material or that sales pursuant to such registration statement may otherwise be resumed. 2.4 Preparation. In connection with the preparation and filing of any registration statement under the Securities Act in which the LLC is a selling shareholder, the Trust shall give the LLC not less than 15 days prior written notice of the preparation of such registration statement and give the LLC and its counsel and accountants the opportunity to review and comment on, at the LLC's expense, the applicable portions, relating to the LLC (including the Selling Shareholder and Plan of Distribution sections), of the registration statement, each prospectus included therein or filed with the Commission, and each amendment thereof or supplement thereto (provided that the LLC shall furnish the Trust with comments on any such amendment or supplement as promptly as the Trust shall reasonably require). 2.5 Indemnification. 2.5.1 Indemnification by the Trust. In the event of any registration of any securities of the Trust under the Securities Act in which the LLC is or may be a selling shareholder, the Trust shall, and hereby does, indemnify and hold harmless, the LLC, its members, officers, employees, agents and affiliates and each Person who controls the LLC within the meaning of the Securities Act, insofar as losses, claims, damages, or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (a) any untrue statement or alleged untrue statement of any fact contained in any registration statement under which such securities were registered under the Securities Act, any preliminary prospectus, final prospectus, or summary prospectus contained therein, or any amendment or supplement thereto, or any omission or alleged omission to state therein a fact required to be stated therein or necessary to make the statements therein in light of the circumstances in which they were made not misleading, or (b) any violation by the Trust, its trustees, officers, employees or agents of this Agreement or any law applicable to and in connection with such registration, and the Trust shall reimburse the LLC and each such member, officer, agent or affiliate and controlling Person of the LLC for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, liability, action or proceeding described in clauses (a) or (b); provided, however, that the Trust shall not be liable in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity with information furnished to the Trust by the LLC. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the LLC or any such director, officer, agent or affiliate or controlling Person and shall survive the transfer of such securities by the LLC. 2.5.2 Indemnification by the LLC If any Registrable Securities are included in any registration statement, the LLC shall indemnify and hold harmless (in the same manner and to the same extent as set forth in Section 2.5.1 above) the Trust and each trustee, -6- officer and employee of the Trust and each Person who controls the Trust within the meaning of the Securities Act, with respect to any statement or alleged statement in or omission or alleged omission from such registration statement, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, if such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with information furnished to the Trust by the LLC. 2.5.3 Notice of Claims, Etc. Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to in the preceding paragraphs of this Section 2.5, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party, immediately give written notice to the latter of the commencement of such action; provided, however, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under the preceding paragraphs of this Section 2.5, except to the extent that the indemnifying party is materially prejudiced by such failure. In case any such action is brought against an indemnified party, unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist in respect of such claim, the indemnifying party shall be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that the indemnifying parties may agree, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof other than reasonable out of pocket costs related to the indemnified party's cooperation with the indemnifying party, unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties arises in respect of such claim after the assumption of the defense thereof. No indemnifying party shall be liable for any settlement of any action or proceeding effected without its written consent, which consent shall not be unreasonably withheld, delayed or conditioned. Consent of the indemnified party shall be required for the entry of any judgment or to enter into a settlement only when such judgment or settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect such claim or litigation. 2.5.4 Contribution. If the indemnification provided for in this Section 2.5 shall for any reason be held by a court to be unavailable to an indemnified party under Section 2.5.1 or 2.5.2 hereof in respect of any loss, claim, damage or liability, or any action in respect thereof, then, in lieu of the amount paid or payable under Sections 2.5.1 or 2.5.2 hereof, the indemnified party and the indemnifying party under Sections 2.5.1 or 2.5.2 hereof shall contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating the same), (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Trust on one hand and the LLC on the other or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect the relative fault of the Trust on one hand and the LLC on the other that resulted in such loss, claim, damage or liability, or action in respect -7- thereof, as well as any other relevant equitable considerations. No Person guilty of fraudulent misrepresentation (within the meaning of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. In addition, no Person shall be obligated to contribute hereunder any amounts in payment for any settlement of any action or claim, effected without such Person's written consent, which consent shall not be unreasonably withheld. 3. Modification; Waivers. This Agreement may be modified or amended only with the written consent of each party hereto. No party shall be released from its obligations hereunder without the written consent of the other party. The observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) by the party entitled to enforce such term, but any such waiver shall be effective only if in a writing signed by the party against which such waiver is to be asserted. Except as otherwise specifically provided herein, no delay on the part of any party hereto in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any waiver on the part of any party hereto of any right, power or privilege hereunder operate as a waiver of any other right, power or privilege hereunder nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any right, power or privilege hereunder. 4. Entire Agreement. This Agreement represents the entire understanding and agreement between the parties hereto with respect to the subject matter hereof and supersedes all other prior and contemporaneous agreements and understandings, both written and oral, between the parties with respect to the subject matter hereof. In the event the LLC elects to sell the Property to the Partnership for cash instead of contributing the Property to the Partnership, pursuant to Section 3 of the Contribution Agreement, this Agreement shall automatically terminate and no party hereto shall have any further rights or obligations hereunder. 5. Severability. If any provision of this Agreement, or the application of such provision to any party or circumstance, shall be held invalid, the remainder of this Agreement or the application of such provision to other parties or circumstances, to the extent permitted by law, shall not be affected thereby; provided, that the parties shall negotiate in good faith with respect to an equitable modification of the provision or application thereof held to be invalid. 6.
