amended February 1, 2006 (the "Agreement");

         WHEREAS, the parties desire to amend the Agreement as set forth in
greater detail below;

         WHEREAS, pursuant to Section 11 of the Agreement, any amendment to the
Agreement is subject to approval (i) by a majority of the Trustees, including a

         WHEREAS, the parties have obtained Trustee approval as set forth above,
and the parties agree that a shareholder vote is not required to amend the
Agreement; and

         NOW, THEREFORE, in consideration of the premises and of the mutual
agreements set forth below, the parties agree to amend the Agreement as follows:

         1. Sections 5, 6 and 7 of the Agreement shall be deleted in their

         prorated according to the proportion which such period bears to a full
         month of 28, 29, 30 or 31 days, as the case may be.
