This Amendment No. 3 amends and supplements the Tender Offer Statement on
Schedule TO filed with the Securities and Exchange Commission on March 13,
2000, as amended by Amendment No. 1 filed with the Securities and Exchange
Commission on April 7, 2000 and Amendment No. 2 filed with the Securities and
Exchange Commission on April 10, 2000 (as amended, the "Schedule TO"),
relating to the offer by ONIX 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 ONIX
Systems Inc., a Delaware corporation (the "Company"), at a purchase price of
$9.00 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 13, 2000 (the "Offer to Purchase"), a copy of which is attached as
Exhibit 12(a)(1) to the Schedule TO, and in the related Letter of Transmittal
(which, together with the Offer to Purchase, constitute the "Offer"), a copy
of which is attached as Exhibit 12(a)(2) to the Schedule TO.
ITEM 11
Item 11 of the Schedule TO is hereby amended and supplemented to
include the following information:
On April 13, 2000, Thermo Instrument announced that, effective on
such date, 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 $9.00 per
Share in cash, without interest thereon. The full text of the press release
is attached as Exhibit 12(a)(12) hereto and incorporated herein by reference.
Prior to the Merger, Thermo Electron Corporation, a Delaware
Corporation ("Thermo Electron") and Thermo Instrument contributed their
Shares to the Purchaser in return for shares of common stock of Purchaser. As
a result of these contributions, immediately prior to the Merger, Thermo
Instrument and Thermo Electron owned 98% and 2%, respectively, of the common
stock of the Purchaser.

THERMO INSTRUMENT TAKES ONIX SYSTEMS PRIVATE
WALTHAM, Mass., April 13, 2000 - Thermo Instrument Systems Inc. (ASE-THI), a
Thermo Electron company, announced today that it has completed a short-form
merger with its ONIX Systems Inc. subsidiary. ONIX Systems 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, ONIX
Systems' common stock will no longer be listed on the American Stock Exchange.
On April 10, 2000, the company announced that Thermo Electron and Thermo
Instrument had acquired more than 90 percent of the outstanding ONIX Systems
shares through a successful tender offer for $9.00 per share in cash. ONIX
Systems shareholders who did not tender their shares will also receive $9.00
per share in the short-form merger. ONIX Systems' 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 $9.00 per share
cash merger consideration. ONIX Systems shareholders should not submit their
stock certificates to the transfer agent until they have received these
materials. Options to purchase ONIX Systems 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.
