Each Interest is a percentage of ownership in the Company. The value of each Interest is the corresponding percentage of the net asset value of the Company (as more fully set forth in the Company documents available with the Securities and Exchange Commission).

The percentage interest in the Company held by PNC at a given time is related to the investments made by other investors in the Company and is subject to change when other investors buy or sell Interests.
