Explanation of Responses:
( 1)  Mr. Eric J. Edidin directly owns 22,069 shares of common stock, $0.001 par value per share (the "Common Stock"), of Arbinet Corporation and controls the voting and disposition of such Common Stock.
( 2)  The filing of this Form 4 shall not be construed as an admission that Messrs. Eric J. Edidin and Joshua A. Lobel, as the managers and members of Canton Holdings, L.L.C. ("Canton"), the general partner of Archer Capital Management, L.P. ("ACM"), are or were for the purposes of Section 16(a) of the Securities Exchange Act of 1934, as amended, the beneficial owners of any of the shares of Common Stock owned by any fund managed by ACM (the "Funds"). Pursuant to Rule 16a-1, Messrs. Edidin and Lobel disclaim beneficial ownership except to the extent of their pecuniary interests in the right to receive profit allocations through the general partner entities of the Funds. This transaction is made by the Funds.
( 3)  ACM controls the voting and disposition of these shares of Common Stock held by the Funds. Canton reports such Common Stock held indirectly by ACM because, as the general partner of ACM, it controls the disposition and voting such Common Stock. Messrs. Edidin and Lobel report such Common Stock held indirectly by Canton because, as the managers and members of Canton, they ultimately control the disposition and voting of such Common Stock. ACM and Canton do not have any pecuniary interest in the Common Stock because they only receive asset-based fees from the Funds.
