ITEM 5.       Other Events

         On October 22, 1999, Stericycle, Inc. (the "Company") and Allied Waste
Industries, Inc. ("Allied") entered into first amendments of the stock purchase
agreement and asset purchase agreement pursuant to which the Company is
acquiring the medical waste business of Browning-Ferris Industries, Inc. ("BFI")
from Allied. Allied acquired BFI in a merger completed in July 1999. The two
amendments reduced the aggregate purchase price from $440 million in cash to
$410.5 million in cash, and also eliminated provisions dealing with adjustments
to the purchase price based on audited financial statements and acquisitions and
dispositions pending closing.

         Copies of the first amendments to the stock purchase agreement and
asset purchase agreement are filed as exhibits to this Report.
