This Amendment is being filed on behalf of Purchaser.

The Offer is made pursuant to the Agreement and Plan of Merger, dated as of April 30, 2012 (as amended, the “Merger Agreement”), among IDT, Pinewood, Pinewood Merger Sub, LLC (“Pinewood LLC”), a Delaware limited liability company and a wholly-owned subsidiary of IDT, and PLX, which contemplates the merger of Pinewood Acquisition with and into PLX (the “Merger”) following the consummation of the Offer. Immediately after the Merger, if certain conditions are met, PLX will merge with Pinewood LLC, with Pinewood LLC continuing as the final surviving entity. IDT has filed a registration statement on Form S-4 (File No. 333-181571) relating to the IDT shares to be issued to the stockholders of PLX (other than IDT) in the Offer and the Merger (as amended, the “Registration Statement”). The Prospectus/Offer to Purchase forms a part of the Registration Statement (as amended, the “Prospectus/Offer to Purchase”).

The terms and conditions of the Offer and the Merger are set forth in the Prospectus/Offer to Purchase and in the related Letter of Transmittal, copies of which are Exhibits (a)(4) and (a)(1)(A) hereto, respectively.

All of the information set forth in the Prospectus/Offer to Purchase and the related Letter of Transmittal, and any prospectus supplement or other amendment or supplement thereto filed with the SEC by IDT, is hereby incorporated by reference in all items in this Schedule TO, except as otherwise set forth below.

Items 1 through 11.

Items 1 through 11 are hereby supplemented and amended as follows:

On December 19, 2012, IDT and PLX issued a joint press release announcing that they had mutually decided to terminate the Merger Agreement and that IDT has withdrawn the Offer. The press release regarding this announcement is attached hereto as Exhibit (a)(5)(X) and is incorporated herein by reference. At the time of withdrawal, certain conditions to the Offer were not satisfied. No shares of PLX common stock were purchased by Pinewood in the Offer, and IDT has instructed Computershare, the exchange agent for the Offer, to promptly return all previously tendered shares.
