Disclaimer Forward-Looking Statements This communication contains “forward-looking statements.” All statements other than statements of historical fact contained in this report are forward-looking statements within the meaning of Section 27A of the United States Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”). Forward-looking statements usually relate to future events and anticipated revenues, earnings, cash flows or other aspects of our operations or operating results. Forward-looking statements are often identified by the words “believe,” “expect,” “anticipate,” “plan,” “intend,” “foresee,” “should,” “would,” “could,” “may,” “estimate,” “outlook” and similar expressions, including the negative thereof. The absence of these words, however, does not mean that the statements are not forward-looking. These forward-looking statements are based on our current expectations, beliefs and assumptions concerning future developments and business conditions and their potential effect on us. While management believes that these forward-looking statements are reasonable as and when made, there can be no assurance that future developments affecting us will be those that we anticipate. Factors that could cause actual results to differ materially from those in the forward-looking statements include, among others, failure to obtain applicable regulatory or stockholder approvals in a timely manner or otherwise; failure to satisfy other closing conditions to the proposed transactions; risks associated with tax liabilities, or changes in U.S. federal tax laws or interpretations to which they are subject; risks that the new businesses will not be integrated successfully or that the combined companies will not realize estimated cost savings, value of certain tax assets, synergies and growth or that such benefits may take longer to realize than expected; failure to realize anticipated benefits of the combined operations; risks relating to unanticipated costs of integration; the potential impact of announcement or consummation of the proposed transaction on relationships with third parties, including advertiser clients, employees and competitors; a decline in advertising revenue and the seasonality of advertising revenue; intense competition in the broadcast radio and media distribution industries; impact on advertising rates and revenues due to technological changes and failure to timely or appropriately respond to such changes; ability to attract new and retain existing advertiser clients in the manner anticipated; increases in or new royalties; high fixed costs; ability to hire and retain key personnel; failure to protect our intellectual property; availability of sources of funding on favorable terms or at all; changes in legislation or governmental regulations affecting the companies; economic, social or political conditions that could adversely affect the companies or their advertiser clients; conditions in the credit markets; and risks associated with assumptions the parties make in connection with the parties’ critical accounting estimates and legal proceedings. All of our forward-looking statements involve risks and uncertainties (some of which are significant or beyond our control) and assumptions that could cause actual results to differ materially from our historical experience and our present expectations or projections. You should carefully consider the foregoing factors and the other risks and uncertainties that affect the parties’ businesses, including those described in the Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other documents filed from time to time with the U.S. Securities and Exchange Commission (the “SEC”) by Entercom Communications Corp.
