    (c)           Capitalization.

     

    Arbinet
hereby represents and warrants that, at the close of business on December 18,
2008, there were 22,579,874 shares of Common Stock issued and
outstanding.

     

    (d)           Defined
Terms.

     

    For
purposes of this Agreement, the terms “Affiliate,” “Associate,” “business
combination,” “control,” “interested stockholder,” “person,” “stock,” “voting
stock,” “owner,” “own,” and “owned” shall have the respective meanings set forth
in Section 203 of the General Corporation Law of the State of Delaware (the
“DGCL”) in effect as of the date hereof.

     

    Section
2.                      Approval of Acquisitions of
Common Stock.  Subject
to the due execution and delivery of this Agreement by the Singer Entities, a
committee of disinterested members of the Board of Directors of Arbinet (the
“Committee”) has approved, for purposes of Section 203 of the DGCL, the purchase
by the Trust of up to 5,141,608 shares of the outstanding voting stock of
Arbinet (the “Share Limit”).

     

    Section
3.                      Stock
Ownership.

     

    (a)           As
a condition to the approval by the Committee of the Transaction, if, at any time
during the three (3) year period from the date hereof, the Singer Entities,
together with their Affiliates and Associates, become the owner of shares of
voting stock exceeding the Share Limit, the parties hereby agree that neither
the Singer Entities nor any of their respective Affiliates or Associates will be
able to engage in any business combination with Arbinet for a period of three
(3) years following the date on which the Singer Entities exceeded the Share
Limit.  Without limiting the foregoing, each of the Singer Entities
hereby represents that any such business combination would be null and
void.

     

    (b)           The
restrictions contained in Section 3(a) of this Agreement shall not apply if the
Singer Entities, together with their Affiliates and Associates, inadvertently
exceeds the Share Limit (the “Inadvertent Transaction”) and (i) as soon as
practicable, but in any event within ten (10) business days of the Inadvertent
Transaction, the Singer Entities, together with their Affiliates and Associates,
divest themselves of ownership of a sufficient number of shares so that the
Singer Entities, together with their Affiliates and Associates, cease to own
more than the Share Limit, and (ii) the Singer Entities, together with their
Affiliates and Associates, would not, at any time within the three (3) year
period immediately prior to a business combination between Arbinet and the
Singer Entities, have been the owner of more than the Share Limit but for the
Inadvertent Transaction.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    (c)           The
restrictions contained in Section 3(a) of this Agreement shall not apply if the
Singer Entities would be entitled to rely on the exemptions from prohibitions on
business combinations set forth in Section 203(b)(6) of the DGCL.

     

    (d)           The
restrictions contained in Section 3(a) of this Agreement shall not apply if the
Singer Entities, together with their Affiliates and Associates, become the owner
of shares of the outstanding voting stock of Arbinet in excess of the Share
Limit as a result of action taken solely by Arbinet; provided, that the
restrictions contained in Section 3(a) of this Agreement shall apply if the
Singer Entities, together with their Affiliates and Associates, thereafter
acquire additional shares of voting stock of Arbinet, except as a result of
further corporate action not caused, directly or indirectly, by the Singer
Entities or their respective Affiliates and Associates.

     

    (e)           Each
of the Singer Entities agrees to cause its respective Affiliates and Associates
to comply with the terms of this Agreement, including the restrictions on
ownership set forth in this Section 3.

     

    Section
4.                      Remedies.  Each
party hereto hereby acknowledges and agrees that irreparable harm would occur in
the event any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached.  It
is accordingly agreed that the parties shall be entitled to specific relief
hereunder, including, without limitation, an injunction or injunctions to
prevent and enjoin breaches of the provisions of this Agreement and to enforce
specifically the terms and provisions hereof in any state or federal court in
the State of Delaware, in addition to any other remedy to which they may be
entitled at law or in equity.  Any requirements for the securing or
posting of any bond with such remedy are hereby waived.

     

    Section
5.                      Entire
Agreement.  This
Agreement contains the entire understanding of the parties with respect to the
subject matter hereof, including without limitation the Original Stock Ownership
Agreement, which understandings or agreements (if any) are of no further force
or effect, and may be amended only by an agreement in writing executed by the
parties hereto.  For the avoidance of doubt, this Agreement does not
supersede or replace that certain Settlement and Standstill Agreement dated as
of July 13, 2007 by and between Arbinet and the Trust, KS, and GS, which remains
in full force and effect in accordance with its terms.

     

    Section
6.                      Notices.  All
notices, consents, requests, instructions, approvals and other communications
provided for herein and all legal process in regard hereto shall be validly
