IDT Announces Publication of Chairman's Book; Purchase The Book And Receive $25 In IDT Long Distance.

HACKENSACK, N.J.--(BUSINESS WIRE)--October 28, 1998--IDT Corporation (NASDAQ: IDTC) today announced that in conjunction with the publication of its CEO Howard Jonas' new book "On A Roll -- From Hot Dog Buns to High-Tech Billions" (Viking, 293 PP, $24.95), IDT is giving away $25 in long distance to anyone who buys the book and switches their phone service to IDT.

The 42 year old founder and CEO of IDT Corp. shares the history and secrets of his success in this free-wheeling account that defines him not only as a latter day Horatio Alger but as a bit of a philosopher and humorist as well.

Business books are rarely page turners. On a Roll is the exception, as Jonas infotains the reader while tracing his business career from humble beginnings purveying hot dogs on a Bronx street corner, through four years as a direct mail entrepreneur (while earning his Harvard BA) to the evolution of IDT from a call-back innovator operating out of an abandoned funeral home to the multimillion dollar international telecommunications juggernaut it is has become.

On a Roll has already received favorable reviews from both mainstream press as well as the trades. Telecom Business magazine has called the book, "A must-read for anyone in the telecom business," and the New York Observer says the book is "Written with humor and bite. Howard Jonas (is) a character dreamed up by a Doctorow or a Vidal."

On A Roll can be purchased through booksellers nationwide or through IDT's web site at www.idt.net
