This presentation contains forward-looking statements, including references to goals, plans, strategies, objectives, projected costs or savings, anticipated future performance, results or events and other statements that are not strictly historical in nature. These statements are based on management’s current expectations, forecasts and assumptions. This means they involve a number of risks and uncertainties that could cause actual results to differ materially from those expressed or implied here. These risks and uncertainties include, but are not limited to the following: prevailing economic conditions and changes affecting the business products industry and the general economy; United’s ability to effectively manage its operations and to implement growth, cost-reduction and margin-enhancement initiatives; United’s reliance on key customers, and the risks inherent in continuing or increased customer concentration; United’s reliance on key suppliers and the supplier allowances and promotional incentives they offer; United’s reliance on independent resellers for a significant percentage of its net sales and, therefore, the importance of the continued independence, viability and success of these resellers; continuing or increasing competitive activity and pricing pressures within existing or expanded product categories, including competition from product manufacturers who sell directly to United’s customers; the impact of a loss of, or substantial decrease in, the availability of products or service from key vendors at competitive prices; United’s ability to maintain its existing information technology systems and the systems and eCommerce services that it provides to customers, and to successfully procure, develop and implement new systems and services without business disruption or other unanticipated difficulties or costs; the creditworthiness of United’s customers; United’s ability to manage inventory in order to maximize sales and supplier allowances while minimizing excess and obsolete inventory; United’s success in effectively identifying, consummating and integrating acquisitions; the risks and expense associated with United’s obligations to maintain the security of private information provided by United’s customers; the costs and risks related to compliance with laws, regulations and industry standards affecting United’s business; the availability of financing sources to meet United’s business needs; United’s reliance on key management personnel, both in day-to-day operations and in execution of new business initiatives; and the effects of hurricanes, acts of terrorism and other natural or man-made disruptions.

Shareholders, potential investors and other readers are urged to consider these risks and uncertainties in evaluating forward-looking statements and are cautioned not to place undue reliance on the forward-looking statements.
