Capitalized terms used but not defined herein are used as defined in the Partnership Agreement.

WHEREAS, Section 13.1(d) of the Partnership Agreement provides that the General Partner, without the approval of any other Partner, may amend any provision of the Partnership Agreement to reflect a change that the General Partner determines does not adversely affect the Limited Partners in any material respect; and

WHEREAS, the Board of Directors of the General Partner has determined that the standard set forth in Section 13.1(d) is satisfied; and

WHEREAS, the General Partner deems it in the best interest of the Partnership to effect this Amendment in order to clarify the definition of “Conflicts Committee”.

NOW, THEREFORE, it is hereby agreed as follows:

A. Amendments. Section 1.1 of the Partnership Agreement is hereby amended to restate the following definition:

B. Agreement in Effect. Except as hereby amended, the Partnership Agreement shall remain in full force and effect.

C. Applicable Law. This Amendment shall be construed in accordance with and governed by the laws of the State of Delaware, without regard to the principles of conflicts of laws.

D. Severability. Each provision of this Amendment shall be considered severable and if for any reason any provision or provisions herein are determined to be invalid, unenforceable or illegal under any existing or future law, such invalidity, unenforceability or illegality shall not impair the operation of or affect those portions of this Amendment that are valid, enforceable and legal.
