ITEM 2.        ACQUISITION OR DISPOSITION OF ASSETS

               On May 7, 1998, pursuant to that certain Agreement and Plan of
Merger dated as of February 11, 1998 (the "Merger Agreement") by and among
Interpore International (the "Company"), Buckeye International, a wholly-owned
subsidiary of the Company ("Sub") and Cross Medical Products, Inc. ("Cross"),
Sub was merged with and into Cross such that Cross became a wholly-owned
subsidiary of the Company (the "Merger"). The Merger Agreement was filed
previously as Exhibit 2.1 to the Company's Current Report on Form 8-K dated
February 17, 1998.

               Special meetings of the shareholders of the Company and Cross at
which the stockholders were asked, pursuant to a Joint Proxy
Statement/Prospectus contained within the Company's Form S-4 Registration
Statement (No. 333-49487) filed with the Securities and Exchange Commission on
April 6, 1998, to consider and vote upon, among other things, the Merger
Agreement were held on May 6, 1998. The shareholders of each of the Company and
Cross approved and adopted the Merger Agreement at their respective meetings.

               Upon consummation of the Merger, each outstanding share of Common
Stock, par value $.01 per share, of Cross (the "Cross Common Stock") was
converted into the right to receive 1.275 shares of Common Stock, no par value
per share, of the Company (the "Company Common Stock"). It is expected that up
to 7,637,285 shares of Company Common Stock will be issued upon conversion of
outstanding shares of Cross Common Stock. The merger consideration was
determined based upon arms-length negotiations between the Company and Cross.

               In addition, on May 7, 1998, the Company issued a press release
announcing the consummation of the Merger, which press release is filed as
Exhibit 99.2 hereto.

California corporation ("Interpore California") and predecessor of Interpore
International, Inc., a Delaware Corporation (the "Registrant"), approved a
change of the Registrant's state of incorporation from the State of California
to the State of Delaware. The reincorporation was effected by a merger of
Interpore California with and into Registrant on May 6, 1998. Registrant, a
Delaware corporation, was organized solely for the purpose of effecting the
reincorporation and is the surviving corporation in the merger.
