(1) For purposes of calculating the filing fee only. This calculation assumes
that 64,072,067 common shares, par value $0.10 per share ("Shares"), of
Safety-Kleen Corp. ("Safety-Kleen") will be exchanged for shares of common
stock, par value $1.00 per share, of Laidlaw Environmental Services, Inc.
("Laidlaw Environmental") and cash. According to Safety-Kleen's Form 10-Q
for the period ended September 6, 1997, as of September 6, 1997, there were
issued and outstanding 58,400,729 Shares of which 601,100 Shares were owned
by a wholly-owned subsidiary of Laidlaw Environmental as of the date of the
filing of this Schedule. Based on the foregoing and assuming that (i) no
Shares have been issued since September 6, 1997 and (ii) no options or
Shares have been issued other than the 5,059,801 options to purchase Shares
reported in Safety-Kleen's Form 10-K for the period ended December 28, 1996,
the maximum number of Shares to be received in exchange would be 64,072,067.
The actual number of Shares will depend on the facts that exist on the date
of the exchange.
(2) Pursuant to Rules 0-11(d) and 0-11(a)(4) of the Securities Exchange Act of
1934, as amended, the filing fee was computed on the basis of $26.875 per
Share, the average of the high and low sales prices of Shares as reported on
the New York Stock Exchange, Inc. Composite Tape on January 26, 1998.
(3) In accordance with Rule 0-11(d) of the Securities Exchange Act of 1934, as
amended, the filing fee equals 1/50 of one percent of the Transaction
Valuation.
[X] Check box if any part of the fee is offset as provided by Rule 0-11(a)(2)
and identify the filing with which the offsetting fee was previously paid.

The undersigned hereby tenders to Laidlaw Environmental Services, Inc., and

"Purchaser"), the above-described shares of common stock, par value $.10 per
share (the "Shares"), of Safety-Kleen Corp., a Wisconsin corporation
("Safety-Kleen"), and the associated Common Share Purchase Rights, (the
"Rights"; unless the context otherwise requires, such Rights are deemed to be
included in all references to the "Shares") issued pursuant to the Rights
Agreement, dated as of November 9, 1988, between Safety-Kleen and First National
Bank of Chicago, as Rights Agent, as amended by a First Amendment to Rights
Agreement, dated as of August 10, 1990 and by a Second Amendment to Rights
Agreement, dated as of November 20, 1997 (as so amended, the "Rights Agreement")
pursuant to the Laidlaw Environmental offer to exchange all of the outstanding
Shares at a price of $18.00 per Share net to the seller in cash (the "Cash
Consideration") and that number of shares of Common Stock, par value $1.00 per
share, of Laidlaw Environmental Services Inc. ("Laidlaw Environmental Common
Stock") equal to the Exchange Ratio (as described in the Amended Exchange Offer
defined below) (the "Stock Consideration") upon the terms and subject to the
conditions set forth in the Amended Prospectus/Offer to Exchange dated January
27, 1998 (the "Amended Exchange Offer"), receipt of which is hereby
acknowledged, and the related Letter of Transmittal (which, together with the
Amended Exchange Offer, together with any amendments or supplements thereto,
constitutes the "Laidlaw Environmental Offer").
Subject to, and effective upon, acceptance for payment for the Shares
validly tendered herewith in accordance with the terms of the Laidlaw
Environmental Offer, the undersigned hereby sells, assigns and transfers to, or
upon the order of, the Purchaser, all right, title and interest in and to all
Shares tendered hereby that are exchanged pursuant to the Laidlaw Environmental
Offer and any and all dividends, distributions (including additional Shares) and
rights declared, paid, issued or issuable with respect to the tendered Shares
after the date of the Laidlaw Environmental Offer and payable or distributable
to the undersigned on a date prior to the transfer to the name of the Purchaser
on Safety-Kleen's stock transfer records of the Shares tendered herewith
(collectively, a "Distribution") and hereby irrevocably constitutes and appoints
the Depositary as the true and lawful agent and attorney-in-fact of the
undersigned with respect to such Shares (and any Distributions), with full power
of substitution and resubstitution (such power of attorney being deemed to be an
irrevocable power coupled with an interest), to (a) deliver Share Certificates
(and any Distribution) or transfer ownership of such Shares (and any
Distributions) on the account books maintained by the Book-Entry Transfer
Facility, together, in either case, with all accompanying evidences of transfer
and authenticity, to or upon the order of the Purchaser, (b) present such Share
Certificates (and any Distributions) for cancellation and transfer of such
Shares on Safety-Kleen's books, and (c) receive all benefits (including all
dividends or distributions resulting from any stock split, combination or
exchange of Shares) and otherwise exercise all rights of beneficial ownership of
such Shares (and any Distributions) all in accordance with the terms of the
Laidlaw Environmental Offer.
The undersigned hereby irrevocably appoints the designees of the Purchaser,
and each of them, the attorneys-in-fact and proxies of the undersigned, each
with full power of substitution to the full extent of such shareholder rights,
with respect to all of the Shares tendered thereby (and any Distributions) which
have been accepted for payment by the Purchaser prior to the time of such vote
or action and with respect to any and all other shares or other securities
issued or issuable in respect of such Shares after the date of the Laidlaw
Environmental Offer. This proxy and power of attorney is coupled with an
interest in the Shares and is irrevocable and is granted in consideration of,
and is effective upon, the acceptance for payment of such Shares by the
Purchaser in accordance with the terms of the Laidlaw Environmental Offer. Such
acceptance for payment shall revoke all other proxies or powers of attorney
granted by the undersigned at any time with respect to such Shares (and any
Distributions) and no subsequent proxies or powers of attorney will be given (or
if given, will be deemed effective) with respect thereto by the undersigned. The
designees of the Purchaser will be empowered to exercise all voting and other
rights of such shareholder as they in their sole discretion may deem proper at
any annual or special meeting of Safety-Kleen's shareholders or any adjournment
or
3
<PAGE> 4
postponement thereof, by consent in lieu of any such meeting or otherwise. The
undersigned understands that in order for Shares to be deemed validly tendered,
immediately upon the Purchaser's acceptance of such Shares (and any
Distributions) for payment the Purchaser or its designee must be able to
exercise full voting rights with respect to such Shares (and any Distributions).
The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Shares (and
any Distributions) tendered hereby and that when the same are accepted for
payment by the Purchaser, the Purchaser will acquire good, marketable and
unencumbered title thereto, free and clear of all liens, restrictions, charges,
encumbrances, conditional sales agreements or other obligations relating to the
sale or transfer thereof, and the same will not be subject to any adverse claim.
The undersigned will, upon request, execute and deliver any signature guarantee
or additional documents deemed by the Depositary or the Purchaser to be
necessary or desirable to complete the sale, assignment and transfer of the
Shares (and any Distributions) tendered hereby. In addition, the undersigned
shall promptly remit and transfer to the Depositary for the account of the
Purchaser any and all Distributions with respect to the Shares tendered hereby,
accompanied by appropriate documentation of transfer and, pending such
remittance or appropriate assurance thereof, the Purchaser shall be, subject to
applicable law, entitled to all rights and privileges as owner of any such
Distributions and may withhold the entire purchase price or deduct from the
purchase price the amount or value thereof, as determined by the Purchaser in
its sole discretion.
No authority herein conferred or agreed to be conferred shall be affected
by, and all such authority shall survive, the death or incapacity of the
undersigned. Any obligation of the undersigned hereunder shall be binding upon
the heirs, executors, personal and legal representatives, administrators,
successors and assigns of the undersigned.
Tenders of Shares (and Rights, if applicable) made pursuant to the Laidlaw
Environmental Offer are irrevocable, except that Shares (and Rights, if
applicable) tendered pursuant to the Laidlaw Environmental Offer may be
withdrawn at any time prior to the Expiration Date (as defined under the caption
"Prospectus Summary -- The Laidlaw Environmental Offer" in the Amended Exchange
Offer) and unless theretofore accepted for payment by Purchaser pursuant to the
Laidlaw Environmental Offer, may also be withdrawn at any time after March 17,
1998.
The undersigned understands that the valid tender of Shares pursuant to any
of the procedures described in under the caption "The Laidlaw Environmental
Offer -- Procedure for Tendering" in the Amended Exchange Offer and in the
instructions hereto and acceptance for payment of such Shares will constitute a
binding agreement between the undersigned and the Purchaser upon the terms and
subject to the conditions of the Laidlaw Environmental Offer.
Unless otherwise indicated herein under "Special Payment Instructions,"
please issue the Laidlaw Environmental Common Stock certificate(s) for Stock
Consideration and the check for the Cash Consideration and for cash in lieu of

Environmental Common Stock certificate(s) for the purchase price and/or return

Message is utilized, if tenders are to be made pursuant to the procedure for
tender by book-entry transfer set forth under the caption "The Laidlaw
Environmental Offer -- Procedure for Tendering" in the Amended Exchange Offer.
Except as hereinafter provided, for a shareholder to tender Shares validly,
certificates for all physically tendered Shares, together with a properly
completed and duly executed Letter of Transmittal (or facsimile thereof), and
any other documents required by this Letter of Transmittal, should be mailed or
delivered to the Depositary at one of the appropriate addresses set forth herein
and must be received by the Depositary on or prior to the Expiration Date (as
defined under the caption "Prospectus Summary -- The Laidlaw Environmental
Offer" in the Amended Exchange Offer).
If stock certificates are not immediately available or time will not permit
all required documents to reach the Depositary on or prior to the Expiration
Date or a shareholder cannot complete the procedure for delivery by book-entry
transfer on a timely basis, such Shares may be tendered if all the following
conditions are met: (a) such tender is made by or through an Eligible
Institution; (b) a properly completed and duly executed Notice of Guaranteed
Delivery substantially in the form provided by the Purchaser is received by the
Depositary on or prior to the Expiration Date; and (c) the certificates for all
physically delivered Shares, together with a properly completed and duly
executed Letter of Transmittal (or facsimile thereof) and any other documents
required by this Letter of Transmittal, are received by the Depositary within
three New York Stock Exchange, Inc. trading days after the date of execution of
the Notice of Guaranteed Delivery. The Notice of Guaranteed Delivery may be
delivered by hand or transmitted by telegram, telex, facsimile transmission or
letter to the Depositary and must include a signature guaranteed by an Eligible
Institution and otherwise comply with the guaranteed delivery procedures set
forth under the caption "The Laidlaw Environmental Offer -- Procedure for
Tendering" in the Amended Exchange Offer.
Shareholders will be required to tender one Right for each Share tendered
in order to effect a valid tender of Shares, unless the Rights Plan Condition
(as defined in the Amended Exchange Offer) has been satisfied or waived. Unless
the Safety-Kleen Distribution Date (as defined in the Amended Exchange Offer)
occurs, a tender of Shares will constitute a tender of the associated Rights. If
the Safety-Kleen Distribution Date occurs and separate certificates representing
the Rights are distributed by Safety-Kleen or the Rights Agent (as defined in
the Amended Exchange Offer) to holders of Shares prior to the time a holder's
Shares are tendered pursuant to the Laidlaw Environmental Offer, certificates
representing a number of Rights equal to the number of Shares tendered must be
delivered to the Depositary, or if available, a Book-Entry Confirmation received
by the Depositary with respect thereto, in order for such Shares to be validly
tendered. If the Safety-Kleen Distribution Date occurs and separate certificates
representing the Rights are not distributed prior to the time Shares are
tendered pursuant to the Laidlaw Environmental Offer, Rights may be tendered
prior to the shareholder receiving the certificates for Rights by use of the
guaranteed delivery procedure described above. If Rights certificates are
distributed but are not available to a shareholder prior to the time Shares are
tendered pursuant to the Laidlaw Environmental Offer, a tender of Shares
constitutes an agreement by the tendering shareholder to deliver to the
Depositary pursuant to the guaranteed delivery procedure described
7
<PAGE> 8
herein, prior to the expiration of the period to be specified in the Notice of
Guaranteed Delivery and the related Letter of Transmittal for delivery of Rights
certificates or a Book-Entry Confirmation for Rights (the "Rights Delivery
Period"), Rights certificates representing a number of Rights equal to the
number of Shares tendered. Laidlaw Environmental reserves the right to require
that it receive such Rights certificates (or a Book-Entry Confirmation with
respect to such Rights) prior to accepting Shares for exchange. If Rights
certificates are distributed, Laidlaw Environmental will distribute a separate
letter of transmittal for such Rights certificates. If Rights certificates are
tendered separately from Shares, then a properly completed Letter of Transmittal
for Rights certificates (or manually executed facsimile thereof) must be
submitted with respect to such Rights. Laidlaw Environmental reserves the right
to require that it receive such Rights certificates (or a Book-Entry
Confirmation with respect to such Rights) prior to accepting Shares for
exchange.
THE METHOD OF DELIVERY OF STOCK CERTIFICATES AND ALL OTHER REQUIRED
DOCUMENTS, INCLUDING DELIVERY THROUGH A BOOK-ENTRY TRANSFER FACILITY, IS AT THE
OPTION AND RISK OF THE TENDERING SHAREHOLDERS AND DELIVERY WILL BE DEEMED MADE
ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF SUCH DELIVERY IS BY MAIL, IT
IS RECOMMENDED THAT SUCH CERTIFICATES AND DOCUMENTS BE SENT BY REGISTERED MAIL,
PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED. IN ALL CASES, SUFFICIENT TIME
SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY.
No alternative, conditional or contingent tenders will be accepted and no
fractional Shares will be purchased. All tendering shareholders, by execution of
this Letter of Transmittal (or facsimile thereof), waive any right to receive
any notice of the acceptance of their Shares for payment.
3. INADEQUATE SPACE. If the space provided herein is inadequate, the
certificate numbers and/or the number of Shares and any other required
information should be listed on a separate schedule attached hereto.
4. PARTIAL TENDERS (APPLICABLE TO CERTIFICATE SHAREHOLDERS ONLY). If
fewer than all the Shares evidenced by any certificate submitted are to be
tendered, fill in the number of Shares which are to be tendered in the box
entitled "Number of Shares Tendered." In such cases, new certificate(s) for the
remainder of the Shares that were evidenced by your old certificate(s) but which
were not tendered by you will be sent to you, unless otherwise provided in the
appropriate box on this Letter of Transmittal, as soon as practicable after the
Expiration Date. All Shares represented by certificates delivered to the
Depositary will be deemed to have been tendered unless otherwise indicated.
5. SIGNATURES ON LETTER OF TRANSMITTAL; STOCK POWERS AND ENDORSEMENTS.
(a) If this Letter of Transmittal is signed by the registered
holder(s) of the Shares tendered hereby, the signature(s) must correspond
exactly with the name(s) as written on the face of the certificate(s)
without alteration, enlargement or any change whatsoever.
(b) If any of the tendered Shares are registered in different names on
several certificates, it is necessary to complete, sign and submit as many
separate Letters of Transmittal as there are different registrations of
certificates.
(c) If the Shares tendered are held of record by two or more joint
holders, all such holders must sign this Letter of Transmittal.
(d) If this Letter of Transmittal or any certificates or stock powers
are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, officers of corporations or others acting in a fiduciary
or representative capacity, such person should so indicate when signing,
and proper evidence satisfactory to the Purchaser of their authority so to
act must be submitted.
(e) If this Letter of Transmittal is signed by the registered
holder(s) of the Shares listed and transmitted hereby, no endorsement of
certificates or separate stock powers are required. If, however, payment is
to be made to, or the certificate(s) for Shares not tendered or accepted
for payment are to be issued in the name of, a person other than the
registered holder(s), then the certificate(s) transmitted
8
<PAGE> 9
hereby must be endorsed or accompanied by appropriate stock powers, in
either case signed exactly as the name(s) of the registered holder(s)
appears on the certificates. Signatures on such certificates or stock
powers must be guaranteed by an Eligible Institution.
(f) If this Letter of Transmittal is signed by a person other than the
registered holder of the certificate(s) tendered, the certificate(s) must
be endorsed or accompanied by appropriate stock powers, in either case
signed exactly as the name(s) of the registered holder(s) appear on the
certificate(s). Signatures on such certificates or stock powers must be
guaranteed by an Eligible Institution unless the signature is that of an
Eligible Institution.
6. STOCK TRANSFER TAXES. Except as otherwise provided in this Instruction
6, transfer taxes on the exchange of Shares pursuant to the Laidlaw
Environmental Offer will be paid by or on behalf of the Purchaser. If, however,
a check or shares of Laidlaw Environmental Common Stock for the purchase price
are to be issued to, or if certificates for Shares not tendered or accepted for
purchase are to be registered in the name of, any person other than the
registered owner(s), or if tendered certificate(s) are registered in the name of
any person other than the person(s) signing this Letter of Transmittal, the
amount of any stock transfer taxes (whether imposed on the registered owner(s)
or such person) payable on account of the transfer to such person will be
deducted from the purchase price unless satisfactory evidence of the payment of
such taxes, or an exemption therefrom, is submitted.
Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the certificates listed in this Letter of
Transmittal.
7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If a check or shares of
Laidlaw Environmental Common Stock for the purchase price of any Shares tendered
hereby are to be issued, or certificate(s) representing Shares not tendered or
not purchased are to be issued or returned, in the name of a person other than
the person(s) signing this Letter of Transmittal or if such check or any such
certificate is to be sent to someone other than the person(s) signing this
Letter of Transmittal or to the person(s) signing this Letter of Transmittal but
at an address other than that shown in the box entitled "Description of Shares
Tendered", the appropriate boxes in this Letter of Transmittal must be
completed. Shareholders delivering Shares tendered hereby by book entry transfer
may request that Shares not purchased be credited to such account maintained at
the Book-Entry Transfer Facility as such shareholder may designate in the box
entitled "Special Payment Instructions". If no such instructions are given, all
such Shares not purchased will be returned by crediting the account at the
Book-Entry Transfer Facility designated herein as the account from which such
Shares were delivered.
8. IRREGULARITIES. All questions as to the validity, form, eligibility
(including timeless of receipt) and acceptance for payment of any tender of
Shares will be determined by the Purchaser, in its sole discretion, which
determination shall be final and binding. The Purchaser reserves the absolute
right to reject any or all tenders, if any, determined by it to be not in
appropriate form or the acceptance of or payment for which may, in the opinion
of the Purchaser's counsel, be unlawful. The Purchaser also reserves the
absolute right to waive any of the conditions of the Laidlaw Environmental Offer
or any defect or irregularity in any tender with respect to any particular
Shares or any particular shareholder, and the Purchaser's interpretations of the
terms and conditions of the Laidlaw Environmental Offer (including these
instructions) shall be final and binding on all parties. Unless waived, any
defects or irregularities in connection with tenders must be cured within such
time as the Purchaser shall determine. None of the Purchaser, the Depositary or
Morrow & Co., Inc. (the "Information Agent") or any other person will be under
duty to give notification of any defects or irregularities in tenders, or incur
any liability for failure to give such notification. Tenders will not be deemed
to have been validly made until all defects and irregularities have been cured
or waived.
9. BACKUP WITHHOLDING, SUBSTITUTE FORM W-9. Under the federal income tax
law, a shareholder whose tendered Shares are accepted for purchase is required
by law to provide the Depositary (as payer) with his correct taxpayer
identification number ("TIN") and certain other information on Substitute Form
W-9 (provided below). If such shareholder is an individual, the taxpayer
identification number is his or her social security number. For businesses and
other entities, the taxpayer identification number is its Employee
Identification Number. If the Shares are in more than one name or are not in the
name of the actual owner,
9
<PAGE> 10
consult the enclosed "Guidelines for Certification of Taxpayer Identification
Number on Substitute Form W-9" for additional guidance on which number to
report. If the Depositary is not provided with the correct taxpayer
identification number, the shareholder may be subject to a $50 penalty imposed
by the Internal Revenue Service, and payments made to such shareholder with
respect to Shares purchased pursuant to the Laidlaw Environmental Offer may be
subject to federal income tax backup withholding. To prevent federal income tax
backup withholding on payments made to a shareholder with respect to Shares
purchased pursuant to the Laidlaw Environmental Offer, each shareholder is
required to notify the Depositary with his correct taxpayer identification
number by completing the form certifying that the taxpayer identification number
provided on Substitute Form W-9 is correct (or that such shareholder is awaiting
a taxpayer identification number) and that (1) the shareholder has not been
notified by the Internal Revenue Service that he is subject to federal income
tax backup withholding as a result of failure to report all interest or
dividends or (2) the Internal Revenue Service has notified the shareholder that
he is no longer subject to federal income tax backup withholding.
Exempt shareholders (including, among others, all corporations and certain
foreign individuals) are not subject to these federal income tax backup
withholding and reporting requirements. In order for a foreign individual to
qualify as an exempt recipient, that shareholder must submit a Form W-8, signed
under penalties of perjury, attesting to that individual's exempt status. A Form
W-8 can be obtained from the Depositary. See the enclosed "Guidelines for
Certificate of Taxpayer Identification Number on Substitute Form W-9" for
additional instructions.
If federal income tax backup withholding applies, the Depositary is
required to withhold 31% of any payments made to the shareholder. Backup
withholding is not an additional tax. Rather, the tax liability of persons
subject to federal income tax backup withholding will be reduced by the amount
of tax withheld. If withholding results in an overpayment of taxes, a refund
generally may be obtained from the Internal Revenue Service.
The box in Part 2 of the form may be checked if the tendering shareholder
has not been issued a TIN and has applied for a number or intends to apply for a
number in the near future. If the box in Part 2 is checked, the shareholder or
other payee must also complete the Certificate of Awaiting Taxpayer
Identification Number. The Depositary is not provided with a TIN within 60 days,
the Depositary will withhold 31% of all payments of the purchase price
thereafter until a TIN is provided to the Depositary.
If the Shares are in more than one name or are not in the name of the
actual owner, consult the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional guidance on which
number to report.
10. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions or requests
for assistance may be directed to, or additional copies of the Amended Exchange
Offer, this Letter of Transmittal, the Notice of Guaranteed Delivery and other
tender offer materials may be obtained from, the Information Agent or the Dealer
Manager at its respective addresses set forth below or from your broker, dealer,
commercial bank or trust company.
10
<PAGE> 11
11. LOST, DESTROYED OR STOLEN CERTIFICATES. If any certificate
representing Shares has been lost, destroyed or stolen, the shareholder should
promptly notify the Depositary by checking the box immediately preceding special
payment/special delivery instructions and indicating the number of Shares lost.
The shareholder will then be instructed as to the steps that must be taken in
order to replace the certificates. This Letter of Transmittal and related
documents cannot be processed until the procedures for replacing lost or
destroyed certificates have been followed.
IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE COPY THEREOF)
TOGETHER WITH CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER OR THE NOTICE

with Laidlaw Environmental's offer to exchange $18.00 net in cash and that
number of shares of common stock, par value $1.00 per share, of Laidlaw
Environmental (the "Laidlaw Environmental Common Stock") equal to the Exchange
Ratio (as such term is defined in the Amended Exchange Offer (as defined below))
for each outstanding common share, par value $0.10 per Share (each, a "Share"
and collectively, the "Shares"), of Safety-Kleen Corp., a corporation
incorporated under the laws of the State of Wisconsin ("Safety-Kleen"),
including the associated common share purchase rights (the "Rights"), issued
pursuant to the Rights Agreement, dated as of November 9, 1988, between
Safety-Kleen and First National Bank of Chicago, as Rights Agent, as amended by
a First Amendment to Rights Agreement, dated as of August 10, 1990 and by a
Second Amendment to Rights Agreement, dated as of November 20, 1997 (as so
amended, the "Rights Agreement"), upon the terms and subject to the conditions
set forth in the Amended Prospectus/Offer to Exchange dated January 27, 1998
(the "Amended Exchange Offer"), and in the revised (yellow) Letter of
Transmittal (which, as amended from time to time, together constitute the

Shareholders will be required to tender one Right for each Share tendered
in order to effect a valid tender of Shares, unless the Rights Plan Condition
has been satisfied or waived. Unless the Safety-Kleen Distribution Date (as
defined in the Exchange Offer) occurs, a tender of Shares will constitute a
tender of the associated Rights. See "The Laidlaw Environmental
Offer -- Procedure for Tendering" in the Amended Exchange Offer.

recipients are required to file tax returns. Beginning January 1, 1984, payers

cause and not to willful neglect.
(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS.--If you fail to
include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an
underpayment attributable to that failure unless there is clear and convincing
evidence to the contrary.
(3) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.
(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment.

LAIDLAW ENVIRONMENTAL STRENGTHENS OFFER FOR
SAFETY-KLEEN -- CASH CONSIDERATION INCREASED
COLUMBIA, South Carolina (January 26, 1998) -- Laidlaw Environmental Services,
Inc. (NYSE:LLE) today announced the terms of a strengthened offer for all the
outstanding shares of Safety-Kleen Corp. (NYSE:SK).
Under the improved offer, each Safety-Kleen shareholder would receive
$30.00 composed of $18.00 in cash and $12.00 in Laidlaw Environmental shares.
The increased cash component is no longer subject to any reduction for estimated
"break-up" fees and expenses agreed to by Safety-Kleen in their previous merger
agreement with Philip Services Corp. and its partners. The actual number of
shares to be issued would be determined by dividing $12.00 by the weighted
average of the trading prices for Laidlaw Environmental shares for 10 days,
selected by lot from the 20 trading days ending three business days immediately
prior to the expiration of the offer, which continues to be 12:00 midnight New
York City time on Friday, February 13, 1998. The number of shares issued would
not be less than 2.24 shares, which would occur if the weighted average trading
price is equal to or greater than $5.35714, and not more than 2.80 shares, which
would occur if the weighted average trading price is equal to or less than
$4.28571.
Commenting on the improved offer, Kenneth W. Winger, Laidlaw Environmental
Services' president and chief executive officer said,
"The new terms we announce today represent both a strengthening and an
effective increase to our previous offer to Safety-Kleen shareholders. These
improved terms clearly put to rest the recent debate as to which offer
represents the best and highest value. We look forward to the Safety-Kleen
shareholders confirming the superiority of the Laidlaw Environmental offer by
the tender of their shares to our bid."
Laidlaw Environmental Services, Inc., headquartered in Columbia, South
Carolina, supplies hazardous and industrial waste management services to
industry and government across North America. The Company provides customers
with local service from more than 100 locations in the United States and Canada,
including 53 service locations, 11 landfills, 6 major incineration facilities
and a number of specialty service locations.
