As a result of the Merger, the Company has become a privately held company; the Company Common Stock has ceased trading on the Over the Counter Bulletin Board ("OTCBB") and will no longer be listed on the OTCBB or Pink Sheets. Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than (i) shares owned by the Parent Group or held in treasury, and (ii) shares in respect of which appraisal rights have been properly exercised under Delaware law) has been canceled and automatically converted into the right to receive $1.40 in cash without interest plus a non-transferable, uncertificated contract right to receive a pro rata share of certain proceeds received by Parent Group or its affiliates in certain circumstances if Parent Group or its affiliates should sell or agree to sell XO Holdings or its assets within one year of the date of execution of the Merger Agreement and such sale is consummated (the "Merger Consideration").
