Selected Financial Data

Danaher Corporation and Sybron Dental Specialties, Inc.

Unaudited Pro Forma Condensed Combined Statement of Earnings

1. Description of Transaction and Basis of Presentation

On May 16 2006, Danaher Corporation (“Danaher”) acquired a majority of the outstanding shares of Sybron Dental Specialties, Inc.(“Sybron”) and on May 19, 2006, acquired all of the remaining outstanding shares of Sybron, in each case for $47 per share. Sybron is a leading manufacturer of a broad range of value-added products for the dental profession and had annual revenues of approximately $650 million in its most recent completed fiscal year. Danaher paid total consideration of approximately $2 billion for the Sybron shares, including transaction costs and net of $94 million of cash acquired, and assumed approximately $182 million of debt. Substantially all of the assumed debt was subsequently repaid or refinanced by Danaher prior to June 30, 2006. Danaher financed the acquisition of shares and the refinancing of the assumed debt primarily with proceeds from the issuance of commercial paper, as discussed below, and to a lesser extent from available cash. The Sybron acquisition resulted in the recognition of a preliminary estimate of goodwill of $1.7 billion primarily related to Sybron’s future earnings and cash flow potential and the world-wide leadership position of Sybron in many of its served markets. Sybron has been included in Danaher’s Consolidated Statement of Earnings since May 19, 2006.

In May 2006, Danaher established a U.S. commercial paper program, and an indirect wholly-owned financing subsidiary of Danaher established a Euro-commercial paper program under which Danaher and its financing subsidiary may issue and sell unsecured, short-term promissory notes in aggregate principal amount not to exceed $2.2 billion. Danaher and its financing subsidiary issued approximately $2 billion of commercial paper in May 2006 and used the proceeds principally to fund its acquisition of Sybron. As of June 30, 2006, $703 million remained outstanding under the U.S. program at an average interest rate of 5.1% and $1,070 million in Euro-denominated commercial paper borrowings (€837 million) at an average interest rate of 2.9% remained outstanding under the Euro program.

The unaudited pro forma condensed combined financial information reflecting the combination of Danaher and Sybron is provided for informational purposes only. The pro forma information is not necessarily indicative of what the companies’ results of operations actually would have been had the merger been completed at the dates indicated. In addition, the unaudited pro forma condensed combined financial information does not purport to project the future financial position or operating results of the combined company.

The unaudited pro forma condensed financial information was prepared using the purchase method of accounting with Danaher treated as the acquirer. Accordingly, we have adjusted the historical consolidated financial information to give effect to the impact of the consideration issued in connection with the merger.

In the Unaudited Pro Forma Condensed Combined Statements of Earnings, a provision for amortization of identified intangible assets including customer relationships and proprietary technology has been made. The amounts allocated to acquired assets and liabilities in the Unaudited Pro Forma Condensed Combined Financial Statements are based on management’s preliminary internal valuation estimates. Definitive allocations will be performed and finalized based upon certain valuations and other studies that will be performed by Danaher with the assistance of outside valuation specialists. Accordingly, the purchase allocation pro forma adjustments included in the Unaudited Pro Forma Condensed Statements of Earnings are preliminary and have been made solely for the purpose of providing unaudited pro forma condensed combined financial information and are subject to revision based on a final determination of fair value.

The Unaudited Pro Forma Condensed Combined Statements of Earnings also include certain purchase accounting adjustments, including items expected to have a continuing impact on the combined results, such as increased depreciation and amortization expense on acquired tangible and intangible assets. The Unaudited Pro Forma Condensed Combined Statements of Earnings do not include the impacts of any revenue, cost or other operating synergies that may result from the merger.

The Unaudited Pro Forma Condensed Combined Statements of Earnings do not reflect nonrecurring charges resulting from the merger. The substantial majority of nonrecurring charges resulting from the merger are comprised of costs associated with the acceleration of stock options under the Sybron option program and certain investment banker, legal and fairness opinion costs incurred by Sybron associated with the transaction. Danaher and Sybron management have reviewed their respective accounting policies and have determined that conforming Sybron’s policies to Danaher’s policies creates no significant differences that impact the Pro Forma Condensed Combined Statements of Earnings other than the timing of the adoption of FAS 123 ( r) “Share-Based Payment” in the quarter-ended December 31, 2005 by Sybron. An appropriate pro forma adjustment has been made to conform the adoption of FAS 123 ( r) in accordance with Danaher’s adoption effective January 1, 2006.

Danaher has a fiscal year end of December 31 whereas prior to the acquisition, Sybron had a September 30 calendar year end. In order to prepare the Unaudited Pro Forma Condensed Combined Statement of Earnings for the year ended December 31, 2005, Sybron’s operating results were first conformed to Danaher’s year-end. This was done utilizing Sybron’s historical audited financial statements as of and for the year ended September 30, 2005, and their historical unaudited financial statements as of and for the three-month periods ended December 31, 2005 and December 31, 2004.
