        This Amendment No. 8 amends and supplements the Tender Offer
Statement on Schedule TO, as amended, (the "SCHEDULE TO"), originally filed with
the Securities and Exchange Commission on April 18, 2006 and as amended and
supplemented by Amendment No. 1 on April 21, 2006, Amendment No. 2 on April 26,
2006, Amendment No. 3 on May 3, 2006, Amendment No. 4 on May 8, 2006, Amendment
No. 5 on May 11, 2006, Amendment No. 6 on May 16, 2006, and Amendment No. 7 on
May 17, 2006, by Danaher Corporation ("DANAHER"), a Delaware corporation, and
Smile Acquisition Corp. ("PURCHASER"), a Delaware corporation and an indirect
wholly owned subsidiary of Danaher. The Schedule TO relates to the offer by
Purchaser to purchase any and all of the outstanding shares of common stock, par
value $0.01 per share (the "SHARES"), of Sybron Dental Specialties, Inc., a
Delaware corporation ("SYBRON"), for $47.00 per Share, net to the seller in
cash, upon the terms and subject to the conditions set forth in the Offer to
Purchase, dated April 18, 2006 (the "OFFER TO PURCHASE"), and in the related
Letter of Transmittal. Copies of the Offer to Purchase and the related Letter of
Transmittal are filed with the Schedule TO as exhibits (a)(1)(A) and (a)(1)(B),
respectively. Capitalized terms used and not defined herein shall have the
meanings assigned such terms in the Offer to Purchase and Schedule TO.

        The Schedule TO, which incorporates by reference the
information contained in the Offer to Purchase, is hereby amended and
supplemented as follows:

        The subsequent offering period in the Offer expired at
midnight, New York City time, on May 18, 2006. Based on the final count by the
Depositary, 38,958,190 Shares were tendered and not properly withdrawn,
including 851,655 Shares tendered by notice of guaranteed delivery, which
represents approximately 96.07% of all outstanding Shares. The Purchaser has
accepted all these Shares for payment and has paid or will promptly pay the
Offer Price in respect of such Shares.

        The full text of the press release announcing the expiration
of the subsequent offering period in the Offer and the final results of the
Offer is attached as Exhibit (a)(5)(H) hereto and is incorporated herein by
reference.

        The Merger was consummated effective as of 9:00 am Eastern
time on May 19, 2006 without a meeting of Sybron's stockholders in accordance
with Delaware's short-form merger statute. As a result of the Merger, each
remaining outstanding Share was converted into the right to receive $47.00 per
Share, net to the seller in cash without interest, other than Shares held by
Danaher or any of its subsidiaries, Sybron, or Shares held by Sybron's
stockholders that perfect their rights to appraisal in accordance with Delaware
law.

        The full text of the press release announcing the consummation
of the Merger is attached as Exhibit (a)(5)(I) hereto and is incorporated herein
by reference.
