                 THERMO FIBERTEK ANNOUNCES DETAILS OF SPIN-OFF

WALTHAM, Mass., July 10, 2001 - Thermo Fibertek Inc. (ASE:TFT) announced today
that the board of directors of Thermo Electron Corporation (NYSE:TMO), which
owns approximately 91 percent of Thermo Fibertek common stock, has approved the
spinoff of Thermo Fibertek as a dividend to Thermo Electron shareholders. On
August 8, 2001, Thermo Electron will distribute all of its shares of Thermo
Fibertek to Thermo Electron shareholders of record on July 30, 2001. Immediately
after the planned distribution, Thermo Electron will no longer own shares of
Thermo Fibertek (to be renamed Kadant Inc., effective July 12, 2001).

Thermo Electron expects to distribute approximately .0611 shares of Kadant
common stock (taking into account a reverse stock split that takes effect this
Thursday, July 12, 2001) for each share of Thermo Electron common stock. The
final ratio will be based on the actual number of Thermo Electron shares
outstanding on the July 30 record date and the actual number of Kadant shares
held by Thermo Electron on the August 8 distribution date. Thermo Electron
shareholders entitled to the dividend will receive stock certificates for whole
shares of Kadant common stock and cash payments for any fractional shares.

Kadant expects to file with the U.S. Securities and Exchange Commission a
preliminary information statement containing details of the distribution and
information about Kadant as an exhibit to a current report on Form 8-K on or
about July 12, 2001. On the distribution date, Thermo Electron will mail a
definitive information statement to Thermo Electron shareholders entitled to
receive the dividend, together with stock certificates representing the
distributed shares.

Kadant Inc. is a leading supplier of a range of products and systems for the
global papermaking and paper-recycling industries, including de-inking systems,
stock-preparation equipment, water-management systems, and papermaking
accessories. Through its majority-owned Thermo Fibergen subsidiary, the company
also develops and commercializes composite building materials produced from
natural fiber and recycled plastic.
