Investors are cautioned that forward-looking statements in this presentation, including but not limited
to statements regarding demand for Company products, anticipated

expenses and profits and IDT’s expectations for the proposed acquisition of PLX Technology, involve
a number of risks and uncertainties that could cause actual results to differ materially from current
expectations. Risks include, but are not limited to, global business and economic conditions,
fluctuations in product demand, manufacturing capacity and costs, inventory management,
competition, pricing, patent and other intellectual property rights of third parties, timely development
and introduction of new products and manufacturing processes, dependence on one or more
customers for a significant portion of sales, successful integration of acquired businesses and
technology, availability of capital, cash flow, the completion of the proposed acquisition of PLX
Technology the timing of the exchange offer and the subsequent merger with PLX Technology,
uncertainties as to how many of PLX Technology’s stockholders will tender their shares of common
stock in the exchange offer, the risk that competing offers or acquisition proposals will be made, the
risk that the exchange offer and the subsequent merger will not close because of a failure to satisfy
one or more of the offer closing conditions (including regulatory approvals) and other risk factors
detailed in the Company’s SEC filings. The Company urges investors to review in detail the risks and
uncertainties
in
the

Additional Info
The exchange offer in connection with the IDT’s proposed acquisition of PLX Technology has not yet
commenced.
This
presentation
is
for
informational
purposes
only
and
shall
not
constitute
an
offer
to
sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any
jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or
qualification under the securities laws of any such jurisdiction.  Any offer will only be made through a
prospectus, which is part of a registration statement on Form S-4, as well as a Tender Offer
Statement on Schedule TO, which will contain an offer to purchase, form of letter of transmittal and
other documents relating to the exchange offer (collectively, the “Exchange Offer Materials”), each to
be filed with the U.S. Securities and Exchange Commission (the “SEC”) by IDT.  In addition, PLX
Technology will file with the SEC a solicitation/recommendation statement on Schedule 14D-9 with
respect to the exchange offer.  IDT and PLX Technology expect to
mail the Exchange Offer
Materials, as well as the Schedule 14D-9, to PLX Technology stockholders.  Investors and security
holders are urged to carefully read these documents and the other documents relating to the
transactions when they become available because these documents will contain important
information relating to the exchange offer and related transactions.  Investors and security holders
may obtain a free copy of these documents after they have been filed with the SEC, and other
annual, quarterly and special reports and other information filed with the SEC by IDT or PLX
Technology, at the SEC’s website at www.sec.gov.  In addition, such materials will be available from
IDT or PLX Technology, or by calling Innisfree M&A Incorporated,
the information agent for the
exchange offer, toll-free at (877) 456-3463 (banks and brokers may call collect at (212) 750-5833).

Additional Info
Neither PLX nor IDT is asking for stockholders to vote or soliciting proxies in connection with the
exchange offer transaction at this time.  Upon consummation of the offer, PLX and IDT may seek
votes or proxies in connection with the proposed back-end merger from holders of PLX shares not
tendered in the offer.  PLX, IDT and their respective officers and directors therefore may be deemed to
be participants in the solicitation of proxies from PLX's stockholders in connection with the proposed
merger. A description of certain interests of the directors and executive officers of PLX is set forth in
PLX's Form 10-K/A, Amendment No. 1, in Part III thereof, which was filed with the SEC on April 27,
2012. A description of certain interests of the directors and executive officers of IDT is set forth in IDT's
proxy statement for its 2011 annual meeting, which was filed with the SEC on August 1, 2011.  To the
extent holdings of either company's securities by their respective directors and certain officers have
subsequently changed, such changes have been reflected on Forms 4 filed with the SEC.
