ITEM 2. ACQUISITION OF ASSETS.

      On March 19, 2001, Bio-Technology General Corp. ("BTG") acquired Myelos
Corporation, a privately-held biopharmaceutical company focused on the
development of novel therapeutics to treat diseases of the nervous system.
Under the terms of the acquisition agreement, BTG paid Myelos shareholders
$35 million in a combination of cash and stock ($14 million in cash and $21
million through the issuance of approximately 2,344,700 shares of BTG common
stock (based on a value of $8.9564, representing the average closing price of
BTG's common stock for the 20 trading day period ending one day prior to the
February 21, 2001 date the acquisition agreement was executed)).

      In the event that (i) BTG publicly announces that it will file a New
Drug Application ("NDA") related to the use of PROSAPTIDE(TM)  to treat
neuropathic pain or neuropathy, (ii) BTG receives FDA minutes stating that
the clinical data possessed by BTG is sufficient for an NDA filing for the
use of PROSAPTIDE to treat neuropathic pain or neuropathy without requiring
any further testing or (iii) BTG initiates preparation of an NDA for
PROSAPTIDE for the treatment of neuropathic pain or neuropathy (the date the
earliest of the foregoing occurs being the "Payment Trigger Date"), then BTG
shall pay to the Myelos shareholders an additional $30 million, at least
approximately $14 million of which shall be paid in shares of BTG common
stock, valued at the average of the closing prices of BTG common stock during
the 20 trading days ending on the Payment Trigger Date, and the remainder
shall be paid in cash, shares of BTG common stock, or a combination thereof,
as determined by BTG in its sole discretion.

      In addition, in the event that the FDA approves the sale of PROSAPTIDE for
the treatment of neuropathic pain or neuropathy, BTG will pay the Myelos
shareholders 15% of the net sales of PROSAPTIDE for the treatment of neuropathic
pain or neuropathy during the 12 month period beginning on the earlier of (i)
the 25th full month after commercial introduction of PROSAPTIDE in the United
States for the treatment of neuropathic pain or neuropathy and (ii) April 1,
2010. At least 50% of this payment must be paid in shares of BTG common stock,
valued at the average of the closing prices of BTG common stock during the 20
days ending one day prior to the payment, and the remainder shall be paid in
cash, shares of BTG common stock, or a combination thereof, as determined by BTG
in its sole discretion.

      In no event will BTG be obligated to issue in aggregate to the Myelos
shareholders more than 10,962,000 shares of BTG common stock. Any amount of the
contingent payments that cannot be paid in shares of BTG common stock shall
instead be paid in shares of BTG's preferred stock. The preferred stock will be
non-voting, non-convertible, non-transferable, non-dividend paying (except to
the extent a cash dividend is paid on the BTG common stock), with no mandatory
redemption for a period of 20 years and one day from the closing date of the
acquisition, and a right to share in proceeds in liquidation, up to the
liquidation amount.

      The transaction will be treated as a "purchase" for accounting
purposes. BTG anticipates that an amount in excess of the purchase price paid
at closing



will be written off as "in process research and development", because the
technology acquired in the acquisition was not fully commercially developed
and had no alternative future use at the time of the acquisition. This
non-cash charge will adversely affect BTG's results of operations for the
first quarter and full year of 2001.
