In some cases, you can identify forward-looking statements because they contain words such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “intends,” “target,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of these words or other similar terms or expressions that concern Market Leader’s expectations, strategy, plans or intentions. These statements include those regarding the closing of the merger transaction, the expected timing of the merger transaction and the potential effects of the merger transaction, including if it does not close.

These statements are not guarantees of future performance or events and are subject to risks, uncertainties and assumptions that could cause actual results or events to vary materially from those indicated in this communication, including: the ability to obtain regulatory approvals of the merger transaction on the proposed terms and schedule; the failure of Market Leader’s shareholders to approve the merger transaction; disruption to our business, including customer, employee and supplier relationships resulting from the merger transaction; the effect of the merger transaction on pricing, spending, third-party relationships and revenues; and other factors described in Market Leader’s reports filed with the SEC, including our annual report for the year ended December 31, 2012 and subsequent quarterly reports filed with the SEC, which risks and uncertainties are incorporated herein by reference. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this communication. Except to the extent required by law, Market Leader disclaims any obligation to update any forward-looking statements after the distribution of this communication, whether as a result of new information, future events, changes in assumptions, or otherwise.
