This Amendment No. 3 amends and supplements the Tender Offer Statement on
Schedule TO filed with the Securities and Exchange Commission on March 17,
2000, as amended by Amendment No. 1 filed with the Securities and Exchange
Commission on April 13, 2000 and Amendment No. 2 filed with the Securities
and Exchange Commission on April 14, 2000 (as amended, the "Schedule TO"),
relating to the offer by BioAnalysis Acquisition Inc., a Delaware corporation
(the "Purchaser") and a wholly-owned subsidiary of Thermo Instrument Systems
Inc., a Delaware corporation ("Thermo Instrument"), to purchase all
outstanding shares of common stock, par value $0.01 per share (the "Shares"),
of Thermo BioAnalysis Corporation, a Delaware corporation (the "Company"), at
a purchase price of $28.00 per Share net to the seller in cash, without
interest thereon, upon the terms and subject to the conditions set forth in
the Offer to Purchase dated March 17, 2000 (the "Offer to Purchase"), a copy
of which is attached to the Schedule TO as Exhibit 12(a)(1), and in the
related Letter of Transmittal (which, together with the Offer to Purchase,
constitute the "Offer"), a copy of which is attached to the Schedule TO as
Exhibit 12(a)(2). This Amendment No. 3 is the final amendment to the Schedule
TO.
ITEM 11
Item 11 of the Schedule TO is hereby amended and supplemented to
include the following information:
On April 20, 2000, Thermo Instrument announced that, effective
April 19, 2000, the Purchaser had merged with and into the Company (the
"Merger"), with the Company continuing as the surviving corporation after the
Merger. Because the Purchaser had acquired in excess of ninety percent (90%) of
the outstanding Shares, the Merger was effected under Section 253 of the
Delaware General Corporation Law with a vote of the Board of Directors of the
Purchaser but without a meeting of stockholders of the Company. At the
effective time of the Merger, the outstanding Shares of the Company were
canceled and Shares other than those owned by the Purchaser, held by
stockholders exercising dissenters' rights and held in the Company's treasury,
were, after being canceled, converted into the right to receive $28.00 per
Share in cash, without interest thereon. The full text of the press release
is attached as Exhibit 12(a)(14) hereto and incorporated herein by reference.
Prior to the Merger, Thermo Electron Corporation, a Delaware
Corporation ("Thermo Electron"), Thermo Instrument and certain wholly-owned
subsidiaries of Thermo Instrument contributed their Shares to the Purchaser
in return for shares of common stock of the Purchaser. As a result of these
contributions, immediately prior to the Merger, Thermo Instrument (including
its wholly-owned subsidiaries) and Thermo Electron owned 79% and 21%,
respectively, of the common stock of the Purchaser.
ITEM 12. EXHIBITS.
Item 12 of the Schedule TO is hereby amended by adding the following:
Exhibit 12(a)(14) Press Release issued by Thermo Instrument on April 20,
2000.

THERMO INSTRUMENT TAKES THERMO BIOANALYSIS PRIVATE
WALTHAM, Mass., April 20, 2000 - Thermo Instrument Systems Inc. (ASE-THI), a
Thermo Electron company, announced today that it has completed a short-form
merger with its Thermo BioAnalysis Corporation subsidiary. Thermo BioAnalysis
will file promptly to terminate the registration of its common stock under the
Securities Exchange Act of 1934, eliminating its obligation to file periodic
financial and other information with the Securities and Exchange Commission.
Starting today, Thermo BioAnalysis' common stock will no longer be listed on the
American Stock Exchange.
On April 14, 2000, the company announced that Thermo Electron and
Thermo Instrument had acquired more than 90 percent of the outstanding Thermo
BioAnalysis shares through a successful tender offer for $28.00 per share in
cash. Thermo BioAnalysis shareholders who did not tender their shares will also
receive $28.00 per share in the short-form merger. Thermo BioAnalysis' transfer
agent, American Stock Transfer & Trust Company, will forward to shareholders who
did not tender their shares in the tender offer detailed instructions regarding
how to surrender their stock certificates in order to receive the $28.00 per
share cash merger consideration. Thermo BioAnalysis shareholders should not
submit their stock certificates to the transfer agent until they have received
these materials. Options to purchase Thermo BioAnalysis common stock that were
outstanding at the time of the merger, and that have not been cashed out at the
election of the holders of such options, have been assumed by Thermo Electron
and converted into options to purchase Thermo Electron common stock.
