Such statements relate to possible future events, including, but not limited to, the termination of the Relationship Agreement. All statements other than statements of historical fact may be forward‐looking statements. Forward‐ looking statements are often, but not always, identified by the use of words such as "anticipate", "believe", "expect", "plan", "estimate", "potential", "will", "should", "continue", "may", "objective" and similar expressions.
