                                                                      Investors are cautioned that forward-looking statements in this presentation, including but
not limited to statements regarding demand for IDT products, anticipated trends in IDT sales, 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 IDT’s SEC filings. IDT urges investors to review in detail the risks and
