ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

                  On May 31, 2001, Harvard Bioscience, Inc., a Delaware
corporation (the "Company"), acquired Union Biometrica, Inc., a Massachusetts
corporation ("Union Biometrica") by merging Union Biometrica with and into the
Company's wholly-owned subsidiary, Union Biometrica, Inc., a Delaware
corporation ("Newco"). The merger was consummated pursuant to an Agreement and
Plan of Merger, dated as of May 31, 2001, by and among the Company, Union
Biometrica and Newco (the "Merger Agreement").

                  The purchase price for Union Biometrica consisted of
approximately 659,282 shares of common stock of the Company, approximately $7.5
million paid in cash, and stock options to purchase approximately 263,202 shares
of common stock of the Company. The amount of the purchase price was determined
pursuant to the Merger Agreement. The Company used general working capital,
together with a portion of the proceeds from its initial public offering in
December 2000, to fund the cash payments that were made in connection with the
merger. The merger is being accounted for as a purchase transaction.

                  Approximately 484,312 shares of common stock of the Company
issued in the merger are being held in escrow to secure the indemnification
obligations of the Union Biometrica stockholders. Two-thirds of the shares held
in escrow are scheduled to be released after approximately 12 months and the
remaining one-third of the shares are scheduled to be released after
approximately 24 months.

                  Prior to the merger, Union Biometrica used its assets for the
development and commercialization of instruments, assays and biological systems
for the automated handling of model organisms. The Company intends to continue
to use the assets it acquired in the merger


                                       2



for this purpose. The Merger Agreement, including the purchase price, was
negotiated at arm's length between the Company and Union Biometrica. Neither the
Company nor any director or officer of the Company was affiliated with or had a
material relationship with Union Biometrica.
