Forward-looking Information

This release contains forward-looking statements that describe the Company’s future plans, strategies and expectations. Forward-looking statements include statements about future performance and results of operations. Forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts. They often include words such as “believe,” “expect,” “anticipate,” “intend,” “plan,” “estimate” or words of similar meaning, or future or conditional verbs such as “would”,

“could”, “should” or “may.” Forward-looking statements speak only as of the date they are made. All forward-looking statements are based on assumptions and involve risks and uncertainties, many of which are beyond our control and which may cause our actual results, performance or achievements to differ materially from the results, performance or achievements contemplated by the forward-looking statements. Such risks and uncertainties include, among other things:

·                  Risks and uncertainties described in our reports filed with the Securities and Exchange Commission, including our most recent Form 10-K.

·                  Competitive pressures among depository and other financial institutions nationally and in our market areas may increase significantly.

·                  Adverse changes in the economy or business conditions, either nationally or in our market areas, could increase credit-related losses and expenses and/or limit growth.

·                  Increases in defaults by borrowers and other delinquencies could result in increases in our provision for losses on loans and related expenses.

·                  Our inability to manage growth effectively, including successful expansion of our customer support, administrative infrastructure and internal management systems, could adversely affect our results of operations and prospects.

·                  Fluctuations in interest rates and market prices could reduce our net interest margin and asset valuations and increase our expenses.

·                  The consequences of continued bank acquisitions and mergers in our market areas, resulting in fewer but much larger and financially stronger competitors, could increase competition for financial services to our detriment.

·                  Our continued growth will depend in part on our ability to enter new markets successfully and capitalize on other growth opportunities.

·                  Changes in legislative or regulatory requirements applicable to us and our subsidiaries could increase costs, limit certain operations and adversely affect financial results and prospects.

·                  Changes in tax requirements, including tax rate changes, new tax laws and revised tax law interpretations may increase our tax expense or adversely affect our customers’ businesses.

In light of these risks, uncertainties and assumptions, you should not place undue reliance on any forward-looking statements in this release. We undertake no obligation to publicly update or otherwise revise any forward-looking statements, whether as a result of new information, future events or otherwise.
