ITEM 2.  ACQUISITIONS OR DISPOSITION OF ASSETS.

         ACQUISITION OF PRION DEVELOPMENTAL LABORATORIES, INC.

         On September 25, 2000, BioLabs, Inc. (the "Registrant") announced
that it had made an investment in Prion Developmental Laboratories, Inc., a
Maryland corporation ("Prion"), pursuant to an Investment Agreement, dated as
of September 8, 2000 (the "Investment Agreement"), by and among Prion,
Efoora, Inc., a Delaware corporation and the parent company of Prion
("Efoora"), and the Registrant. The Registrant invested One Million Ten
Dollars ($1,000,010.00) on the date of the transaction, and committed to
invest a further One Million Dollars ($1,000,000.00) on the later to occur of
September 30, 2000, and Prion's execution of research agreements with certain
universities, upon the condition that such research agreements be executed no
later than December 30, 2000. In return for its initial investment, the
Registrant received from Prion one million (1,000,000) shares of Prion common
stock, $0.00001 par value ("Prion Common Stock") at a price per share of One
Dollar ($1.00), and a warrant (the "Prion Warrant") to purchase an additional
one million shares of Prion Common Stock at an exercise price of Forty Cents
($0.40) per share. In return for its secondary investment, the Registrant
will receive an additional One Million Shares of Prion Common Stock.

         The Investment Agreement also grants to the Registrant the right to
receive warrants to purchase up to an additional One Million (1,000,000)
shares of Prion Common Stock at any time until March 8, 2001, such warrant to
contain terms and conditions identical to the Prion Warrant, except that the
purchase price and duration of such warrant, and the exercise price at which
the underlying shares of Prion Common Stock may be purchased, shall be as
mutually agreed at the time such right is exercised.

         The Prion Warrant is exercisable until March 8, 2002, and may, at
the Registrant's option, be exchanged for a warrant to purchase One Million
(1,000,000) shares of the common stock of Efoora, on terms and conditions
otherwise identical to those contained in the Prion Warrant.

         Prion is engaged in the business of developing rapid diagnostic
assays for the detection of prion disease in humans, animals, food and
related products and byproducts.

         The Investment Agreement and the Prion Warrant are being filed
herewith as Exhibits 99.1 and 99.2, respectively, to this Current Report. The
press release described in the first paragraph of this Item 2 is being filed
herewith as Exhibit 99.3 to this Current Report. The Exhibits are
incorporated herein by reference.
