NOW, THEREFORE, in consideration of the mutual agreements and covenants set forth herein, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Board Representation.

(a) The RP Investor II shall have the right to designate one trustee (such trustee and any trustee who subsequently replaces such trustee in accordance with this Agreement, a “Primary RP Trustee”) for election to the Board of Trustees of the Trust (the “Board”) in accordance with, and subject to the conditions of, Section 10(a)(iii) of the Partnership Agreement. In the event that any Primary RP Trustee shall die, retire from or be removed from the Board, a substitute Primary RP Trustee shall be designated by the RP Investor

II for election to the Board pursuant to this Agreement. Each of the Shareholders shall vote, or cause to be voted, all of the Common Shares beneficially owned or held of record by such Shareholder at any regular or special meeting of the shareholders of the Trust called for the purpose of filling positions on the Board, or in any written or electronic consent executed in lieu of such a meeting of shareholders, to cause the election to the Board of the Primary RP Trustee. The RP Investor II has named Paisley Boney as the initial Primary RP Trustee.

(b) The RP Investor II shall have the exclusive right to cause the removal of the Primary RP Trustee (such trustee, a “Removed Trustee”) and designate a replacement RP Trustee in accordance with, and subject to the conditions of, Section 10(a)(iii) of the Partnership Agreement. If the Removed Trustee does not resign or if the Board does not fill the resulting vacancy with the replacement Primary RP Trustee within five (5) business days of written notice of the RP Investor II, each of the Shareholders shall act by written or electronic consent to remove the Removed Trustee and elect a replacement Primary RP Trustee (or, if such written or electronic consent would not be effective for any reason, by causing the Trust to call a special meeting of the shareholders of the Trust and voting all of the Common Shares beneficially owned or held of record by such Shareholder at such special meeting of the shareholders in favor of such actions).

(c) If an Event of Default (as defined in the Partnership Agreement) occurs and remains uncured for a period of sixty (60) calendar days following the Trust’s receipt of written notice from the RP Investor II: (i) the RP Investor II shall have the right by written notice to the Trust (the “Board Increase Election”) to request that the number of trustees then constituting the Board be increased by a number of trustees that would result in the RP Investor II being entitled to designate for nomination and election a majority of the members of the Board (each such additional trustee and any trustee who subsequently replaces such trustee in accordance with this Agreement, an “Additional RP Trustee” and, together with the Primary RP Trustee, the “RP Trustees”); (ii) the removal of any Additional RP Trustees may only be effected in accordance with the terms of Section 1(b) of this Agreement; (iii) in the event that any Additional RP Trustee shall die, retire from or be removed from the Board, a substitute Additional RP Trustee shall be designated by the RP Investor II; and (iv) each of the Shareholders shall vote, or cause to be voted, all of the Common Shares beneficially owned or held of record by such Shareholder at any regular or special meeting of the shareholders of the Trust called for the purpose of filling positions on the Board, or in any written or electronic consent executed in lieu of such a meeting of shareholders, to cause the election to the Board of the Additional RP Trustees. If for any reason the number of trustees on the Board is not increased in accordance with (i) above so that the RP Trustees constitute a majority of the Board, each of the Shareholders shall act by written or electronic consent to remove such number of trustees and elect Additional RP Trustees so that the RP Trustees constitute a majority of the Board (or, if such written or electronic consent would not be effective for any reason, by causing the Trust to call a special meeting of the shareholders of the Trust and voting all of the Common Shares beneficially owned or held of record by such Shareholder at such special meeting of the shareholders in favor of such actions).

(d) Each Shareholder shall vote any additional Common Shares or other voting securities of the Trust acquired by such Shareholder after the date hereof in accordance with the provisions of Paragraphs (a), (b) and (c) above.

(e) The Primary RP Trustee shall serve on each committee of the Board and shall be provided substantially comparable access to the business records and operational matters of the Trust as the other members of the Board.

(f) The RP Investor II shall have the right to designate one individual as a non-voting observer to the Board (a “Board Observer”), who shall initially be Tom Gilbane. Any Board Observer shall be entitled to attend meetings of the Board and any committee of the Board and to receive all information provided to the members of the Board or its committees (including minutes of previous meetings of the Board or such committees); provided, that (i) the Board Observer shall not be entitled to vote on any matter submitted to the Board or any of its committees nor to offer any motions or resolutions to the Board or such committees; and (ii) the Trust may withhold information or materials from the Board Observer and exclude such Board Observer from any meeting or portion thereof if (as determined by the Board in good faith) access to such information or materials or attendance at such meeting would adversely affect the attorney-client or work product privilege between the Trust and its counsel. The RP Investor II shall have the exclusive right to remove a Board Observer and designate a replacement Board Observer at any time.

(g) Each Shareholder has executed and delivered the Irrevocable Limited Proxy attached hereto as Exhibit A (the “Limited Proxy”) that grants the RP Investor II (or its designee) an irrevocable limited proxy to vote all Common Shares held by such Shareholder or execute a written or electronic consent in lieu of meeting of shareholder of the Trust on behalf of such Shareholder, each in accordance with this Section 1.
