   BAIN CAPITAL AGREES TO MAKE $75 MILLION STRATEGIC INVESTMENT IN STERICYCLE



    LAKE FOREST, Ill., Aug 16, 1999 - Stericycle, Inc. (Nasdaq: SRCL), one of
the largest providers of regulated medical waste management services in the
United States, today announced that it has entered into a definitive agreement
with certain funds managed by Bain Capital Inc. ("Bain") under which such funds
will purchase $75 million of newly issued convertible preferred stock of
Stericycle concurrently with the closing of Stericycle's purchase of the
regulated medical waste management business of Browning-Ferris Industries, Inc.
and Allied Waste Industries, Inc.

    Stericycle's newly issued convertible preferred stock is expected to pay
dividends in kind at the rate of 3.375% per annum and will be convertible into
Stericycle common stock at a conversion price of $17.50 per share. At closing,
Bain's investment will represent approximately 22% of Stericycle's common stock
on a fully diluted, as-if-converted basis.

    Concurrently with the closing of Bain's investment, Mr. Stephen G. Pagliuca
and Mr. John P. Connaughton of Bain will join Stericycle's board of directors,
expanding Stericycle's board from seven to nine members.

    Mark C. Miller, President and Chief Executive Officer of Stericycle said,
"Bain's investment represents a historic milestone for Stericycle. Bain has
achieved significant success investing in growth companies over the past15
years. Bain has clearly demonstrated with this agreement its confidence in our
aggressive growth strategy. Our entire team is excited about the opportunity to
work with the Bain team in building Stericycle."

    John P. Connaughton, a Managing Director of Bain, commented, "We are pleased
to work with the outstanding Stericycle team to support this attractive
transaction. This acquisition will enhance Stericycle's ability to more
effectively service its customers. We look forward to Stericycle's continued
growth."

    Founded in 1989, Stericycle has grown to be one of the largest providers of
regulated medical waste management services in the United States. With the
successful completion of its acquisition of the regulated medical waste
management business of Browning-Ferris Industries, Inc. and Allied Waste
Industries, Inc., Stericycle will become the leading U.S. medical waste services
provider.
