Introductory Note

Arbinet-thexchange, Inc. (“Arbinet” or the “Company”) is filing this amendment to its Current Report on Form 8-K, originally filed with the Securities and Exchange Commission on June 12, 2007 (the “Original Filing”). This Current Report on Form 8-K/A is being filed solely for the purpose of correcting a scrivener’s error in Exhibit 10.1 filed pursuant to Item 9.01(d): Resignation Agreement by and between J. Curt Hockemeier and Arbinet-thexchange, Inc., dated as of June 11, 2007 (the “Resignation Agreement”).

The following statement was included in Section 4(a) of the Resignation Agreement that was filed with the Original Filing:

“However, in consideration for you entering into this Agreement and provided that you abide by the terms herein, the Company shall allow you to vest 42,005 of the Unvested Option Shares as of the Resignation Date (“Additional Options”).”

The reference to 42,005 of the Unvested Option Shares (as defined in the Resignation Agreement) should have been to 52,930 of the Unvested Option Shares, which number ties to the information set forth in the table in Section 4(a) that summarizes Mr. Hockemeier’s stock options in the Company as of the Resignation Date (as defined in the Resignation Agreement). The Resignation Agreement has been corrected so that the statement in Section 4(a) reads as follows:

“However, in consideration for you entering into this Agreement and provided that you abide by the terms herein, the Company shall allow you to vest 52,930 of the Unvested Option Shares as of the Resignation Date (“Additional Options”).”

The corrected information is set forth in Exhibit 10.1 to this Current Report on Form 8-K/A. Except as noted above there have been no other changes to the Original Filing.
