Any statements about Questerre’s expectations, beliefs, plans, goals, targets, predictions, forecasts, objectives, assumptions, information and statements about possible future events, conditions and results of operations or performance are not historical facts and may be forward-looking. Forward-looking information is often, but not always, made through the use of words or phrases such as “anticipates”, “aims”, “strives”, “seeks”, “believes”, “can”, “could”, “may”, “predicts”, “potential”, “should”, “will”, “estimates”, “plans”, “mileposts”, “projects”, “continuing”, “ongoing”, “expects”, “intends” and similar words or phrases suggesting future outcomes. Forward-looking information in this news release includes but is not limited to the appointment of a mediator, the application to defer the next steps in the court timetable and the mediation process.

Although Questerre believes that the expectations reflected in these forward-looking statements are reasonable, undue reliance should not be placed on them because Questerre can give no assurance that they will prove to be correct.

Current conditions, economic and otherwise, render assumptions, although reasonable when made, subject to greater uncertainty.
