ITEM 2.           ACQUISITION OR DISPOSITION OF ASSETS

         On June 29, 2001, American Biogenetic Sciences, Inc. (the "Company")
and its wholly owned subsidiary, Stellar Bio Systems, Inc. ("Stellar"),
completed the sale of Stellar's in vitro immunoflourescent antibody slide format
assay business and Stellar's mouse serum business (collectively, the "Business")
to PanBio InDx Inc. ("PanBio InDx"), a wholly owned subsidiary of PanBio
Limited, an Australian company. The Company and Stellar received a purchase
price of $1.2 million cash paid at closing and the right to receive up to an
additional $540,000 payable quarterly over three years, based on revenues of
certain portions of the Business.

         Assets sold in the transaction included rights to specified products;
rights under certain contracts and leases; inventory, accounts receivable and
intellectual property related to the Business; rights to the name "Stellar";
certain computer hardware and software and other tangible assets and goodwill.
PanBio InDx assumed certain liabilities of the Business, including accounts
payable.

         The terms of this disposition of assets are more fully described in the
Asset Purchase Agreement, dated June 29, 2001, by and among Stellar, the
Company, PanBio InDx and PanBio Limited, filed as an exhibit to this Form 8-K.

         In connection with the sale of the assets, the Company entered into a
Manufacture and Supply Agreement with PanBio InDx and PanBio Limited, pursuant
to which PanBio InDx will manufacture the Company's thrombus precursor protein
diagnostic test kit for annual periods that may be terminated on notice given at
least 45 days prior to the end of the term.

         The terms of this transaction and the consideration Stellar and the
Company received were a result of arm's length negotiations between
representatives for Stellar and the Company and representatives of PanBio InDx
and PanBio Limited.
