BOSTON—PerkinElmer, Inc. (NYSE: PKI) announced today that it has determined the purchase price to be paid in connection with its previously announced cash tender offer and consent solicitation for any and all of its outstanding 8 7/8% Senior Subordinated Notes due 2013 and that $269.891 million, or 99.96% of the aggregate outstanding principal amount of notes were validly tendered. The tender offer and the consent solicitation are subject to the terms and conditions set forth in PerkinElmer’s Offer to Purchase and Consent Solicitation Statement dated October 25, 2005.

Holders of notes who validly tender notes prior to the initial settlement date will receive total consideration per $1,000 principal amount of notes tendered of $1,119.64, which amount includes a consent payment of $20, plus accrued and unpaid interest up to the date of the payment. Holders of notes will validly tender notes on the initial settlement date and prior to the expiration time of 9:00 a.m., New York City time, on November 23, 2005, will receive total consideration per $1,000 principal amount of notes tendered of $1,118.65, which amount also includes a consent payment of $20, plus accrued and unpaid interest up to the date of payment. The consent payment will be paid for all validly tendered notes, including those tendered subsequent to the November 7, 2005 consent deadline. The purchase price for the notes was calculated in the manner described in the Offer to Purchase using a yield equal to a fixed spread of 50 basis points plus 4.448%, which is the yield to maturity of the 3.000% U.S. Treasury Note due February 15, 2008 (corresponding to the bid-side price, as indicated on Bloomberg screen PX5 at 2:00 p.m., New York City time, on November 8, 2005).

PerkinElmer may elect to accept for payment all notes validly tendered on the initial settlement date, which is to occur promptly after today’s pricing. PerkinElmer anticipates that the initial settlement date may be November 14, 2005. However, PerkinElmer reserves the right, in its sole discretion, to extend or forgo the initial settlement date. The tender offer will expire at 9:00 a.m., New York City time, on November 23, 2005, unless extended, and PerkinElmer expects the final settlement date, if any, to occur promptly after the expiration of the tender offer.
