Item 8.01

Other Events.

LoopNet, Inc. (the “Company”) and CoStar Group, Inc. (“CoStar”) announced that they have reached agreement on a mutually acceptable consent order with the staff of the Federal Trade Commission (“FTC”). The consent order is subject to review and approval by the Commissioners of the FTC and if approved by the Commissioners, it would clear the way for the merger of the Company and CoStar that was previously announced on April 27, 2011. The companies are not providing details of the consent order pending this Commission review and approval. The Company and CoStar hope to complete the merger by April 30, 2012. Completion of the merger remains subject to the expiration or termination of the waiting period under the Hart-Scott-Rodino Act, which would occur upon the approval by the FTC Commissioners, and other customary closing conditions.

Cautionary Statements Regarding Forward-Looking Statements.

This Current Report on Form 8-K contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements include, but are not limited to, statements about the timing of the merger, the companies’ plans, objectives, expectations and intentions and other statements including words such as “hope,” “anticipate,” “may,” “believe,” “expect,” “intend,” “will,” “should,” “plan,” “estimate,” “predict,” “continue” and “potential” or the negative of these terms or other comparable terminology. Such statements are based upon the current beliefs and expectations of management of the Company and CoStar and are subject to significant risks and uncertainties. Actual results may differ materially from the results anticipated in the forward-looking statements. The following factors, among others, could cause or contribute to such differences: the possibility that the Commissioners of the FTC will not approve the consent order in a timely manner or at all; the possibility that the FTC will request additional extensions to the waiting period imposed by the HSR Act; the possibility that conditions, divestitures or changes relating to the operations or assets of the Company and CoStar will be required to obtain required governmental clearances or approvals, including, but not limited to, clearance or approval by the FTC; the possibility that the merger does not close, including, but not limited to, due to the failure to obtain governmental clearances or approvals; the risk that expected cost savings or other synergies from the merger may not be fully realized or may take longer to realize than expected; the risk that the businesses of the Company and CoStar may not be combined successfully or in a timely and cost-efficient manner; the risk that business disruption relating to the merger may be greater than expected; and failure to obtain any required financing on favorable terms. Additional factors that could cause results to differ materially from those anticipated in the forward-looking statements can be found in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011 and CoStar’s Annual Report on Form 10-K for the year ended December 31, 2011, each filed with the SEC, including in the “Risk Factors” section of each of these filings, and each company’s other filings with the SEC available at the SEC’s website (http://www.sec.gov). Neither the Company nor CoStar undertakes any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
