These forward-looking statements are intended to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, but are not limited to, statements about (i) the benefits of the merger between Piedmont Bancorp, Inc. ("Piedmont") and UBSI (the "Merger"), including future financial and operating results, cost savings enhancements to revenue and accretion to reported earnings that may be realized from the Merger; (ii) UBSI's and Piedmont's plans, objectives, expectations and intentions and other statements contained in this press release that are not historical facts; and (iii) other statements identified by words such as "expects," "anticipates," "intends," "plans," "believes," "seeks," "estimates," "targets," "projects," "will," or words of similar meaning generally intended to identify forward- looking statements. These forward-looking statements are based upon the current beliefs and expectations of the respective managements of UBSI and Piedmont and are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond the control of UBSI and Piedmont. In addition, these forward-looking statements are subject to assumptions with respect to future business strategies and decisions that are subject to change. Actual results may differ materially from the anticipated results discussed in these forward-looking statements because of possible uncertainties.

The following factors, among others, could cause actual results to differ materially from the anticipated results or other expectations expressed in the forward-looking statements: (1) the businesses of UBSI and Piedmont may not be combined successfully, or such combination may take longer, be more difficult, time-consuming or costly to accomplish than expected; (2) the expected growth opportunities or cost savings from the Merger may not be fully realized or may take longer to realize than expected; (3) deposit attrition, operating costs, customer losses and business disruption following the Merger, including adverse effects on relationships with employees, may be greater than expected; (4) the regulatory approvals required for the Merger may not be obtained on the proposed terms or on the anticipated schedule or may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the transaction; (5) the shareholders of Piedmont may fail to approve the Merger; (6) legislative or regulatory changes, including changes in accounting standards, may adversely affect the businesses in which UBSI and Piedmont are engaged; (7) the possibility of increased scrutiny by, and/or additional regulatory requirements of, governmental authorities as a result of the transaction or the size, scope and complexity of UBSI's business operations following the Merger; (8) competitive pressures on product pricing and services; (9) success, impact, and timing of UBSI's business strategies, including market acceptance of any new products or services; (10) disruption from the Merger making it more difficult to maintain relationships with employees, customers or other parties with whom UBSI and Piedmont have business relationships; (11) diversion of management time on Merger-related issues; (12) risks relating to the potential dilutive effect of the shares of UBSI common stock to be issued in the Merger; (13) reputational risk and the reaction of each company's customers, suppliers, employees or other business partners to the transaction; (14) the failure of the closing conditions in the merger agreement to be satisfied, or any unexpected delay in closing the transaction or the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement; (15) the outcome of any legal proceedings that may be instituted against UBSI or Piedmont; (16) general competitive, economic, political and market conditions and other factors that may affect future results of UBSI and Piedmont, including changes in asset quality and credit risk; the inability to sustain revenue and earnings growth; changes in interest rates and capital markets; inflation; customer borrowing, repayment, investment and deposit practices; the impact, extent and timing of technological changes; capital management activities; and other actions of the Federal Reserve Board and legislative and regulatory actions and reforms; (17) uncertainty in U.S. fiscal and monetary policy, including the interest rate policies of the Federal Reserve Board; (18) volatility and disruptions in global capital and credit markets; and (18) the nature, extent, timing, and results of governmental actions, examinations, reviews, reforms, regulations, and interpretations. Additional factors, that could cause actual results to differ materially from those expressed in the forward-looking statements are discussed in UBSI's reports (such as Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K) filed with the SEC and available on the SEC's Internet site (http://www.sec.gov).
