        - ZERO COUPON DEBENTURE TENDER OFFER TO EXPIRE DECEMBER 27, 2002

Boston - PerkinElmer, Inc. (NYSE: PKI) announced that it has substantially
completed its previously announced refinancing plan to repay existing debt in
order to extend existing shorter-term debt maturities. Today the company repaid
its existing bank debt and synthetic lease by completing the sale of $300
million aggregate principal amount of ten-year senior subordinated notes and
entering into new senior secured credit facilities for a $315 million six-year
term loan and a $100 million revolving credit facility. PerkinElmer also
accepted for payment $110,319,000 aggregate principal amount of its outstanding
6.80% Notes due October 15, 2005 pursuant to its cash tender offer and consent
solicitation. The final step of the refinancing plan, PerkinElmer's pending cash
tender offer to purchase its Zero Coupon Convertible Debentures due August 7,
2020, is scheduled to expire at 12:00 midnight, New York City time, on Friday,
December 27, 2002.

Senior Subordinated Notes and Secured Credit Facilities

PerkinElmer sold $300 million aggregate principal amount of senior subordinated
notes in an institutional private placement. The notes have been guaranteed on a
senior subordinated basis by certain of PerkinElmer's domestic subsidiaries.

PerkinElmer borrowed the full amount available under the term loan at the
closing of the new senior secured credit facilities. PerkinElmer did not draw
upon the $100 million revolving credit facility, which remains available for the
company's working capital needs. The revolving credit facility has a five-year
term. A portion of the proceeds from the term loan is being used to purchase the
tendered 6.80% notes and a portion of the proceeds, together with proceeds from
the sale of the company's senior subordinated notes, will be used to purchase
the zero coupon convertible debentures that are tendered.

6.80% Notes

The tendered 6.80% notes represented approximately 96% of the total outstanding
6.80% notes. PerkinElmer will pay an aggregate of $111,768,350.37 for the
tendered 6.80% notes. Each holder who tendered 6.80% notes and the related
consents at or before 5:00 p.m., New York City time, on December 6, 2002, the
consent expiration date, will receive $1,013.41 for each $1,000 principal amount
of tendered 6.80% notes, including a $15 consent payment. Each holder who
tendered notes and the related consents after the consent expiration date will
receive $998.41 for each $1,000 principal amount of tendered 6.80% notes.

The 6.80% notes tender offer commenced on November 22, 2002 and expired at 10:00
a.m., New York City time, on Thursday, December 26, 2002. It is anticipated that
State Street Bank and Trust Company, as Depositary for the tender offer and
consent solicitation, will pay noteholders on or about December 26, 2002. On
December 6, 2002, the expiration date for the 6.80% notes consent solicitation,
PerkinElmer announced that it had received the requisite consents to amend the
indenture under which the 6.80% notes were issued. PerkinElmer and State Street
Bank and Trust Company, as Trustee, executed a supplemental indenture, which
became effective as of December 26, 2002, eliminating substantially all of the
restrictive covenants from the indenture, as more fully described in
PerkinElmer's Offer to Purchase and Consent Solicitation Statement dated
November 22, 2002.
