All of these types of statements, other than statements of historical fact included in this communication, are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as “may,” “could,” “should,” “expect,” “plan,” “project,” “intend,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “pursue,” “target,” “continue,” the negative of such terms or other comparable terminology.

The forward-looking statements contained in the Proxy Statement/Prospectus are largely based on the Partnership’s expectations, which reflect estimates and assumptions made by the Partnership’s management. These estimates and assumptions reflect the Partnership’s best judgment based on currently known market conditions and other factors. Although the Partnership believes such estimates and assumptions to be reasonable, they are inherently uncertain and involve a number of risks and uncertainties that are beyond the Partnership’s control. In addition, management’s assumptions about future events may prove to be inaccurate. All readers are cautioned that the forward-looking statements contained in the Proxy Statement/Prospectus are not guarantees of future performance, and the Partnership’s expectations may not be realized or the forward-looking events and circumstances may not occur. Actual results may differ materially from those anticipated or implied in the forward-looking statements due to factors described in the section of the Proxy Statement/Prospectus entitled “Risk Factors.” The forward-looking statements in the Proxy Statement/Prospectus speak only as of the date of this document; we disclaim any obligation to update such statements unless required by securities law, and we caution you not to unduly rely on them.
