We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995, and are including this statement for purposes of said safe harbor provisions.

Although we believe that our plans, intentions, and expectations as reflected in these forward-looking statements are reasonable, we can give no assurance that they will be achieved or realized.

Our ability to predict results or the actual effects of our plans and strategies is inherently uncertain. Accordingly, actual results, performance, or achievements could differ materially from those contemplated, expressed, or implied by the forward-looking statements contained in this report.
