SECURITIES AND EXCHANGE COMMISSION Washington, D. C. 20549 FORM 8-K CURRENT REPORT Pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 Date of Report: December 31, 1996 MILLIPORE CORPORATION (Exact name of registrant as specified in its charter) Massachusetts 0-1052 04-2170233 (State or other (Commission (IRS Employer jurisdiction of File Number) Identification incorporation or No.) organization) 80 Ashby Road, Bedford, Massachusetts 01730 (Address of principal executive offices) (Zip Code) Registrant's telephone number, including area code: 617) 275-9200 Item 2. Acquisition or Disposition of Assets On December 31, 1996 Registrant acquired the Amicon Separation Science Business ("Amicon") of W. R. Grace & Co. ("Grace"), in a $125 million cash transaction. Amicon's business consists principally of the development, manufacture and marketing of protein purification tools for the research laboratory and for biotechnology manufacturing. Based in Beverly, Massachusetts, Amicon has approximately $60 million in annual sales, and has manufacturing operations in the U.S. and Europe. The purchase price resulted from an "auction" conducted by and on behalf of Grace. Registrant's successful bid was based on its evaluation of the value of Amicon to it and included among others an analysis of the present cash value of Amicon's projected future earnings stream ("discounted cash flow") and a comparable acquisition analysis. There is no relationship between the Registrant or any of its affiliates and Grace, nor between Grace and any director or officer of the Registrant or any associate of such director or officer. The funds used to consummate the acquisition were obtained pursuant to a bridge loan agreement with The First National Bank of Boston. Amicon's products and technology complement those of the Registrant in both Registrant's analytical life science and biopharmaceutical manufacturing businesses, with the result that the Registrant will continue to use the bulk of the Amicon assets in the same manner as previously utilized. Item 7. Financial Statements and Exhibits (a) The financial statements of the Amicon business required by this item will be filed by an amendment to this Report on or before March 15, 1997. (b) The pro-forma financial information required by this item will be filed by the same amendment referred to in (a) above. (c) Exhibits (2) Plan of Acquisition, Reorganization, etc. Amicon Worldwide Purchase and Sale Agreement, as Amended Page 4 (All schedules and certain exhibits have been omitted. Registrant agrees to furnish supplementally a copy of any omitted schedule or exhibit to the Commission upon request.)
