                               March 2, 1998
 
DEAR SAFETY-KLEEN
SHAREHOLDER:              We believe Safety-Kleen's Board has lost sight of one
                          simple issue: SHAREHOLDER VALUE.
 
                          In its relentless pursuit of a proposed $27.00 per
                          share merger with S-K Parent Corp. (the "Buyout
                          Merger") THE BOARD HAS CHOSEN TO REJECT THE OPINION OF
                          ITS OWN INVESTMENT BANKERS, to ignore the votes of
                          shareholders and to support what we believe to be an
                          inferior offer.
 
                          When you vote on the Buyout Merger on March 9,
                          consider the following.
 
LAIDLAW ENVIRONMENTAL'S
OFFER PROVIDES GREATER
VALUE, UPSIDE POTENTIAL
AND SYNERGIES             Laidlaw Environmental is offering $30(1) for each
                          share of Safety-Kleen.
                          The Laidlaw Environmental offer also allows
                          Safety-Kleen shareholders to participate in the value
                          that we believe will be created by combining two of
                          the leading service companies in the hazardous and
                          industrial waste management business.
 
                          The strategic merger of Safety-Kleen with Laidlaw
                          Environmental will combine the strengths of
                          Safety-Kleen's premier service delivery and recycling
                          system and its 400,000 small to medium sized customers
                          with Laidlaw Environmental's network of fully
                          permitted service centers and its 18,000 medium to
                          large customers. We believe this merger will generate
                          $100-$130 million of cost savings synergies that will
                          benefit ALL continuing Laidlaw Environmental
                          shareholders.

- --------------------------------------------------------------------------------
 
FACT: SAFETY-KLEEN'S
OWN INVESTMENT BANKER
AND ISS SAY THE LAIDLAW
ENVIRONMENTAL OFFER IS
SUPERIOR                  "...it is our opinion as investment bankers that it is
                          more likely than not that, as of the time of the
                          anticipated closing of the Current LLE Offer, the
                          value of the consideration which would be received
                          under the Current LLE Offer would exceed the value of
                          the consideration which would be received in the
                          Merger."
 
                                    From letter dated January 31, 1998 from
                                    William Blair & Company, L.L.C. to the Board
                                    of Directors of Safety-Kleen Corp.
 
                          "On balance, we believe that [Laidlaw Environmental's]
                          offer is superior to the proposed Philip Group
                          merger.... Due to these factors, we believe that [the
                          Safety-Kleen] shareholders should not support this
                          merger agreement."
 
                                    From February 5, 1998 report of
                                    Institutional Shareholder Services, the
                                    leading independent proxy advisory firm.

- --------------------------------------------------------------------------------
 
- ------------------------------------
(1) The Offer consists of $18 cash and $12 of Laidlaw Environmental Services
    Inc. Common Stock, assuming the fair market price of Laidlaw Environmental
    Common stock is not less than $4.28571. The actual fair market value of the
    Laidlaw Environmental Common Stock to be exchanged pursuant to the Laidlaw
    Environmental offer may vary, and will be less than $12.00 if the market
    price on the day of exchange is less than $4.28571.

THE SAFETY-KLEEN BOARD
CONTINUES TO IGNORE THE
WISHES OF SHAREHOLDERS    
                          SAFETY-KLEEN SHAREHOLDERS SIMPLY HAVE NOT DEMONSTRATED
                          SUPPORT FOR THE BUYOUT MERGER. Although approximately
                          54% of the Safety-Kleen shareholders tendered into our
                          Offer as of February 13, 1998, we recognize that these
                          shareholders could also vote in favor of the Buyout
                          merger. However, Safety-Kleen has twice adjourned the
                          shareholder meeting at which the Buyout Merger is to
                          be considered -- from February 11 to February 25, and
                          from February 25 to March 9.
 
                          Based on information released by Safety-Kleen after
                          the February 5 adjournment, as of February 25 LESS
                          THAN 50%of the outstanding Safety-Kleen shares have
                          been voted in favor of the Buyout Merger.
 
                          When will the Board face the fact -- SHAREHOLDERS DO
                          NOT SUPPORT THE BUYOUT MERGER.
 
WE HAVE GONE TO COURT
TO SEEK RELIEF            Because less than one-half of Safety-Kleen's
                          shareholders supported the Buyout Merger proposal and
                          in light of Safety-Kleen's adjournment of the February
                          25 special meeting to March 9, Laidlaw Environmental
                          is seeking an injunction requiring the Safety-Kleen
                          Board to remove all remaining impediments to the
                          Laidlaw Environmental offer.
 
NOW YOU SHOULD TELL THE
BOARD TO STOP
STONEWALLING -- VOTE
AGAINST THE BUYOUT
MERGER                    Preserve your opportunity to participate in Laidlaw
                          Environmental's premium offer by voting AGAINST THE
                          BUYOUT MERGER PROPOSAL.
                          Laidlaw Environmental is committed to its offer. If
                          Safety-Kleen shareholders reject the Buyout Merger,
                          Laidlaw will not withdraw its offer until
                          Safety-Kleen's shareholders have had sufficient time
                          to accept the Laidlaw Environmental offer.
 
                          Let the Safety-Kleen board of directors know YOU WILL
                          NOT SETTLE FOR THE BUYOUT MERGER.
