The Issuer's Shares have been acquired on behalf of SIA's and SFI's clients. In pursuing such investment purposes, the Sit Entities purchased the Shares based on the Sit Entities' belief that the Shares represented an attractive investment opportunity, and the Sit Entities may further purchase, hold, vote, trade, sell or otherwise deal in the Shares at the time, and in such manner, as they deem advisable to benefit from, among many things, changes in market prices of such Shares, the market prices of such Shares relative to the value of the Issuer's assets, changes in the Issuer's investment strategy, and composition of the Issuer's portfolio. The Sit Entities intend to review their investment in the Issuer's Shares on a continuing basis and may also propose or take one or more of the actions described in subsections (a) through (j) of Item 4 of Schedule 13D, including engaging in discussions with management, the Board of Directors and shareholders concerning, among other things, the Issuer's performance, the market prices of the Issuer's Shares relative to the value of the Issuer's assets, the distribution rate, the Issuer's capitalization, the Issuer's investment strategy and the Issuer's portfolio holdings.
