Subsequently, the Debtors sought and received an order directing the joint administration of the Chapter 11 Cases under the caption In re: Primus Telecommunications Group, Incorporated, et al., Debtors Case No. 09-10867. On June 12, 2009 (the “Confirmation Date”), the Bankruptcy Court entered an order confirming the Joint Plan of Reorganization of Primus Telecommunications Group, Incorporated and its Affiliate Debtors (the “Plan”) pursuant to Chapter 11 of the Bankruptcy Code. On July 1, 2009 (the “Effective Date”), the Debtors consummated their reorganization under the Bankruptcy Code and the Plan became effective. Under the Plan, shares of Common Stock and Class A Warrants were distributed to certain prepetition creditors of the Debtors. The Class A Warrants are exercisable into shares of Common Stock of the Issuer and were issued in the following three separate series: Class A-1 Warrants, Class A-2 Warrants and Class A-3 Warrants.

Pursuant to the Plan, on July 1, 2009, (a) the Fund was issued (i) 897,369 shares of Common Stock, (ii) 186,951 Class A-1 Warrants, (iii) 186,951 Class A-2 Warrants, and (iv) 186,951 Class A-3 Warrants; (b) Managed Account 1 was issued (i) 73,387 shares of Common Stock, (ii) 15,288 Class A-1 Warrants, (iii) 15,288 Class A-2 Warrants, and (iv) 15,288 Class A-3 Warrants; and (c) Managed Account 2 was issued (i) 22,039 shares of Common Stock, (ii) 4,591 Class A-1 Warrants, (iii) 4,591 Class A-2 Warrants, and (iv) 4,591 Class A-3 Warrants.
