Safe Harbor Statement: Statements in this press release may contain forward-looking statements that involve risks and uncertainties, some of which are beyond our control (for example, general economic conditions). Our actual results could differ significantly from the results described in the forward-looking statements. Factors that could cause such differences include changes in governmental regulation of medical waste collection and treatment and increases in transportation and other operating costs, as well as the other factors described in our filings with the U.S. Securities and Exchange Commission. As a result, past financial performance should not be considered a reliable

indicator of future performance, and investors should not use historical trends to anticipate future results or trends. We make no commitment to disclose any subsequent revisions to forward-looking statements.
