Item 8.01. Other Events.

On June 19, 2009, a putative class action captioned Masucci v. FiberNet Telecom Group, Inc., et al., was filed in the Court of Chancery of the State of Delaware against FiberNet Telecom Group, Inc. (the “Company”) and its directors, as well as Zayo Group, LLC (“Zayo Group”) and Zayo Merger Sub, Inc., a direct wholly owned subsidiary of Zayo Group (“Merger Sub”). The action was brought by a purported stockholder of the Company, on behalf of a putative class of Company stockholders and, among other things, seeks to enjoin the consummation of the merger of Merger Sub with and into the Company (the “Merger”) and seeks an award of monetary damages, costs and disbursements. Plaintiff alleges that the decisions by the Company’s directors to approve the Merger constituted breaches of their respective fiduciary duties because they did not engage in a fair process to ensure the highest possible purchase price for the Company’s stockholders, did not properly value the Company and failed to disclose material facts regarding the proposed Merger. Plaintiff also contends that the Company, Zayo Group and Merger Sub aided and abetted the alleged breaches of fiduciary duties by the Company’s directors. Plaintiff has also filed a motion for preliminary injunction and for expedited proceedings. The Company intends to defend the action vigorously but can provide no assurance as to the manner or timing of the resolution of the action. For more information, please see the verified class action complaint attached hereto as Exhibit 99.1 and incorporated herein by reference.
