Fisher Scientific and Apogent Give Notices of Conversion Right

HAMPTON AND PORTSMOUTH, N.H., June 15, 2004 — Fisher Scientific International Inc. (NYSE: FSH) and Apogent Technologies Inc. (NYSE: AOT) announced today that they have provided conversion-right notices to the holders of Apogent’s Floating Rate Senior Convertible Contingent Debt Securities due 2033 (CUSIP No. 03760AAJ0) (the “Floating Rate Securities”) and Apogent’s 2.25 percent Senior Convertible Contingent Debt Securities due 2021 (CUSIP Nos. 03760AAE1 and 03760AAD3) (the “2.25 percent Securities,” and together with the Floating Rate Securities, the “Securities”). Their right to convert such Securities is a result of the planned merger between Fisher and Apogent.

     The companies expect the merger to be completed early in the third quarter if Fisher’s stockholders approve the issuance of shares of Fisher common stock in the merger and Apogent’s stockholders approve and adopt the merger agreement and the merger, and other conditions to the merger, as detailed in the merger agreement, are satisfied. The current conversion price of the Floating Rate Securities is $33.090 per share of Apogent common stock and the current conversion price of the 2.25 percent Securities is approximately $30.492 per share of Apogent common stock.

     The notice provides that holders may surrender the Securities for conversion beginning June 16 until 15 days after the effective date of the merger. Accordingly, if the merger occurs on July 1, the conversion right will expire on July 16. Conversions are effective as of the close of business on the date that the Securities are properly surrendered for conversion. In accordance with the terms of the Securities, holders surrendering their Securities before the effective date of the merger will be entitled to receive shares of Apogent common stock. Holders surrendering their Securities after the effective date of the merger will be entitled to receive the corresponding number of shares of Fisher common stock, based on the exchange ratio in the merger of 0.56 shares of Fisher common stock for each share of Apogent common stock.

     The Apogent common stock issuable upon conversion of the 2.25 percent Securities before the planned merger would be freely tradable, but the Fisher common stock issuable upon conversion of the 2.25 percent Securities after the planned merger would not be freely transferable under the securities laws unless an exemption from registration under the Securities Act of 1933 is otherwise available.

     The Apogent common stock issuable upon conversion of the Floating Rate Securities before the planned merger and the Fisher common stock issuable upon conversion of the Floating Rate Securities after the planned merger would not be freely transferable under the securities laws unless an exemption from registration under the Securities Act of 1933 is otherwise available.

     The Bank of New York is the Trustee for the Securities. Copies of the notices of conversion right may be obtained at no charge from Apogent by calling its Director of Investor Relations at 603-433-6131. All questions relating to the mechanics of the conversions should be directed to Bernard Arsenec at the Bank of New York, 212-815-5098.
