Teradyne Announces Proposed Offering of Convertible Senior Notes

NORTH READING, Mass.--(Business Wire)--
Teradyne, Inc. (NYSE: TER) today announced that it intends to offer, subject to
market conditions and other factors, $150 million aggregate principal amount of
convertible senior notes due 2014, pursuant to an automatically effective
registration statement filed with the Securities and Exchange Commission today.
Teradyne also expects to grant the underwriters an option to purchase up to an
additional $22.5 million aggregate principal amount of notes, within 13 days of
the initial issuance of the notes, to cover over-allotments.

In connection with the offering, Teradyne intends to enter into convertible note
hedge and warrant transactions with an affiliate of an underwriter. These
transactions are expected to reduce the potential dilution to Teradyne's common
stock upon future conversions of the notes.

Teradyne expects to use the net proceeds of the offering and the proceeds of the
warrant transaction to repay amounts outstanding under, and to terminate, its
senior secured credit facility. In addition, Teradyne expects to use a portion
of the proceeds from the offering to fund the convertible note hedge
transactions. Remaining proceeds will be used for general corporate purposes.

Goldman, Sachs & Co. and Merrill Lynch & Co. are acting as joint book-running
managers for the offering.

buy the securities described herein, nor shall there be any sale of these
