Forward-Looking Statements
This Current Report on Form 8-K and the materials incorporated by reference herein include "forward-looking statements" including, without limitation, statements regarding the proposed acquisition of Jumptap and the combined company's forecasted financial results, anticipated reach, capabilities and opportunities for the combined company, expected benefits to advertisers and developers and market opportunities, that are subject to risks, uncertainties and other factors that could cause actual results or outcomes to differ materially from those contemplated by the forward-looking statements.  These forward-looking statements include, but are not limited to, plans, objectives, expectations and intentions and other statements contained in these materials that are not historical facts.  These statements are sometimes identified by words and phrases such as "will," "may," "expect," "to be," or words or phrases of similar meaning. As a result of the ultimate outcome of such risks and uncertainties, Millennial's actual results could differ materially from those anticipated in these forward-looking statements.  These statements are based on Millennial's current beliefs and expectations, and there are a number of important factors that could cause the actual results or outcomes to differ materially from those indicated by these forward-looking statements, including, without limitation, whether the proposed acquisition is ultimately consummated; the ability to integrate Millennial's and Jumptap's businesses; disruption from the transaction making it more difficult to maintain relationships with clients, suppliers or employees; risks related to the successful offering of the combined company's products and services; the risk that the anticipated benefits of the acquisition may not be realized; and other risks that may impact Millennial's business.  Other risk factors are set forth under the caption "Risk Factors," in Millennial's Quarterly Report on Form 10-Q for the quarter ended June 30, 2013, filed with the SEC on August 14, 2013, which is available on a website maintained by the SEC at www.sec.gov.
