               PROXY STATEMENT FOR ANNUAL MEETING OF SHAREHOLDERS
                            TO BE HELD MAY 10, 1996
 
  This Proxy Statement was first mailed on or about March 22, 1996 to
shareholders of Safety-Kleen Corp. ("Safety-Kleen" or the "Company") in
connection with the solicitation of proxies by Safety-Kleen's Board of
Directors (the "Board of Directors" or "Board") to be used at the 1996 annual
meeting of Safety-Kleen's shareholders and any adjournments thereof. The
meeting will be held on Friday, May 10, 1996, at 10:00 A.M., Chicago time, at
The Westin Hotel O'Hare, 6100 River Road, Rosemont, Illinois 60018.
 
                                    PROXIES
 
  The accompanying proxy is solicited on behalf of the Board of Directors. The
cost of soliciting proxies will be borne by the Company. In addition to
solicitation by mail, officers and regular employees of the Company may solicit
proxies by telephone, facsimile or in person without extra compensation. Morrow
& Co., Inc. has been engaged by the Company to assist in the solicitation of
proxies for an anticipated fee of not more than $10,000, plus out-of-pocket
cost and expenses.
 
  Proxies in the accompanying form, properly executed and received by Safety-
Kleen's Secretary prior to the meeting and not revoked, will be voted as
directed thereon or, in the absence of such direction, will be voted as
follows: (i) FOR the election to the Board of Directors of the three persons
nominated by the Board; (ii) FOR approval of the request to increase the number
of shares of common stock authorized to be issued under the Company's 1993
Stock Option Plan; (iii) AGAINST approval of a shareholder proposal requesting
the Company to declassify the Board of Directors; (iv) AGAINST approval of a
shareholder proposal regarding "Golden Parachute" agreements; and (v) in
accordance with the judgment of the persons acting under the proxies with
respect to any other matters that may come before the meeting. Any such proxy
may be revoked by the person or persons giving it at any time before it has
been voted by giving written notice of such revocation to Safety-Kleen's
Secretary, by submitting prior to the vote a subsequently dated proxy or by
attending the meeting and voting in person. Attendance at the meeting by a
shareholder will not in itself revoke a previously delivered proxy.
 
                   RECORD DATE, SHARES OUTSTANDING AND VOTING
 
  Shareholders of record as of the close of business on March 7, 1996 are
entitled to vote at the annual meeting. On March 7, 1996, 57,868,541 shares of
Safety-Kleen's common stock, par value $.10 per share (the "Common Stock"),
were outstanding and are entitled to be voted at the annual meeting. Each share
of Common Stock entitles the holder to one vote on each matter to be acted on.
A majority of the Common Stock outstanding on the record date will constitute a
quorum for the transaction of business at the annual meeting, but if a quorum
should not be present, the meeting may be adjourned from time to time until a
quorum is obtained. For quorum and voting purposes, abstentions are treated as
present and entitled to vote and thus have the effect of a vote against a
matter. The Company will treat broker non-votes as present for purposes of
establishing a quorum. Broker non-votes as to any proposal will be treated as
not entitled to vote on that matter and thus
 
                                       1
<PAGE>
 
not counted in determining whether a matter requiring approval of a majority of
the shares present and entitled to vote has been approved or whether a
plurality of the vote of the shares present and entitled to vote has been cast.
 
COMMON STOCK OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
 
  The following table sets forth the Common Stock ownership as of February 28,
1996 of (i) shareholders who, to the knowledge of the Company, owned
beneficially more than 5% of the outstanding shares of Common Stock; (ii) each
of the Company's directors; (iii) each named executive officer and (iv) the
Company's directors and executive officers as a group.

(1) Under regulations of the Securities and Exchange Commission, persons who
    own or have the power to vote or dispose of shares, either alone or jointly
    with others, are deemed to be the beneficial owners of such shares. Such
    persons are also deemed to be the beneficial owners of shares beneficially
    owned by certain close family members.

(2) Shares subject to options exercisable within 60 days of February 28, 1996
    are considered outstanding for the purpose of determining the percent of
    the class held by the holder of such option, but not for the purpose of
    computing the percentage held by others.
(3) The shares shown for Joan Emery Lammers include 683,760 shares contributed
    by or on behalf of Mrs. Lammers in December 1992 to Circle L Enterprises
    L.P. (the "Circle L Limited Partnership"). See Note (5).
(4) 683,760 of the shares attributed to Mr. Emery were contributed to the
    Circle L Limited Partnership in January of 1996. See Note (5).
(5) Karl G. Otzen and Lucy T. Otzen (the "Otzens") are husband and wife. For
    purposes of this table each is deemed to own shares owned by the other, and
    accordingly the same shares are shown opposite each of their names. In
    December 1992, the Otzens caused 683,760 of the shares shown opposite each
    of their names to be contributed to Circle L Enterprises L.P. Karl G.
    Otzen, Lucy T. Otzen, Joan Emery Lammers and her husband (the "Lammers")
    each own one-sixth and William H. Emery owns one-third of the voting stock
    of the corporation that is general partner of the partnership, and each
    serves as one of that corporation's seven directors. Because Mr. Emery, the
    Otzens and the Lammers share voting power over all of the shares held by
    the Partnership, each of them may be deemed to "own" all shares in the
    Partnership under the criteria governing this table. To enhance clarity of
    presentation, however, the shares contributed to the Partnership by Mr.
    Emery are shown only opposite his name in the table, those shares
    contributed by Joan Emery Lammers are shown only opposite her name, and the
    shares contributed by the Otzens are shown only opposite their respective
    names. The shares shown opposite the Otzens' names also include: 757,721
    shares owned by trusts of which the Otzens are co-trustees, 9,100 shares
    owned by a trust of which The Northern Trust Company is trustee and 26,250
    shares subject to options exercisable by Karl G. Otzen within 60 days of
    February 28, 1996.
(6) All shares are owned by a trust of which The Northern Trust Company is
    trustee.
(7) Includes 73 shares owned by his wife and 385,604 shares subject to options
    exercisable within 60 days of February 28, 1996.
(8) Includes 275,000 shares owned by Breslube Industries, Ltd. of which 100% is
    owned by Mr. Chalhoub. Also included are 59 shares owned by his wife, 75
    shares owned by his son and 55,625 shares subject to options exercisable
    within 60 days of February 28, 1996.
(9) Includes 68,752 shares subject to options exercisable within 60 days of
    February 28, 1996.
(10) Includes 26,250 shares subject to options exercisable within 60 days of
     February 28, 1996.
(11) Includes 30,223 shares owned by his wife and 26,250 shares subject to
     options exercisable within 60 days of February 28, 1996. Mr. Gwillim is
     also a co-trustee for 45,827 shares held in an irrevocable trust for which
     he has no beneficial ownership; such shares are not included in the table.
(12) Includes 700 shares owned by his wife and 44,062 shares subject to options
     exercisable within 60 days of February 28, 1996.
(13) Includes 3,750 shares subject to options exercisable within 60 days of
     February 28, 1996.

                DIRECTORS' COMMITTEES, MEETINGS AND COMPENSATION
 
  The Board of Directors has, pursuant to its powers, designated Compensation,
Audit, Environmental, Executive and Nominating Committees of the Board. The
committee members have been identified above. The primary functions of the
Compensation Committee are to act on behalf of the Board of Directors in
connection with the administration of the Company's Management Incentive Plan
and the Company's stock option plans, to determine compensation of all officers
of the Company and to approve salary grades of certain management positions.
The Compensation Committee met two times in 1995. The primary functions of the
Audit Committee are to recommend to the Board of Directors the selection of
independent auditors; to review the scope of the independent auditor's
examination; to review with the independent auditors the results of their
audits; to review the adequacy of internal controls with the independent
auditors, the Company's internal auditors and certain officers of the Company
and to perform such other duties as shall from time to time be delegated to the
Audit Committee by the Board. The Audit Committee met twice in 1995. The
primary function of the Environmental Committee is to monitor the Company's
environmental, health and safety performance and policies. The Environmental
Committee, which was formed on May 12, 1995, met once in 1995. The primary
function of the Executive Committee is to exercise the powers of the full Board
of Directors with respect to the management of the Company's business where it
would be impractical to either convene a special meeting of the full Board of
Directors to deal with any matter or delay action until the next regular
meeting of the Board of Directors. The primary function of the Nominating
Committee is to identify and propose to the full Board nominees, brought to its
attention by directors and officers, to fill vacancies on the Board as they
occur. The Nominating Committee will consider nominations by shareholders,
submitted in accordance with the Company's by-laws. The Company's by-laws
currently require persons submitting nominations to provide certain information
not less than 60 nor more than 90 days prior to the annual meeting, and, in
certain instances, within 10 days after the date of the annual meeting is
announced. Neither the Executive Committee nor the Nominating Committee met in
1995.
 
  In 1995, the Board of Directors met four times. Directors who are employees
of the Company receive no additional compensation for their services as
directors. In 1995, directors who were not employees received $12,000 plus
$2,000 for each Board or committee meeting attended, and were reimbursed for
travel and other expenses related to attendance at Board and committee
meetings. During 1995, each incumbent director attended at least 75%, in the
aggregate, of all meetings of the Board and the committee(s) on which such
director served.
 
  In February 1988, a non qualified stock option plan for outside directors
(the "Directors' Plan") was adopted and approved by the shareholders at the
1988 annual meeting of shareholders. The Directors' Plan allows eligible
directors of the Company to purchase up to an aggregate of 300,000 shares of
Common Stock at a price equal to the fair market value of the Common Stock on
the date options are granted. Only directors who are not employees of the
Company are eligible to participate in the Directors' Plan. Pursuant to the
Directors' Plan, an option to purchase 15,000 shares of the Company's Common
Stock (i) was granted to each director serving on the Board on the date the
Directors' Plan was adopted and (ii) is granted to each new outside director at
the time such director is named or appointed to the Board. The Directors' Plan
also provides for the automatic grant of a second option to purchase 15,000
shares to each outside director on the fifth anniversary of the initial grant
of options to such director, but only if such director is still serving on the
Board at that time. Options are exercisable 25 percent annually, on a
cumulative basis, starting one year from date of grant and expire ten years
from date of grant.

(1) All options are nonqualified, expire 10 years from date of grant, were
    issued at fair market value on the date of grant and vest at the rate of
    25% per year beginning one year from grant date. Options granted to
    executive officers have a tandem limited stock appreciation right (LSAR)
    which entitles the officer to elect to receive a "Change of Control Value"
    (as described in the 1993 Stock Option Plan) of the option in cash in the
    event a change of control occurs.
(2) The potential realizable value portion of the foregoing table illustrates
    the gain that might be realized upon the exercise of the options
    immediately prior to the expiration of their term, assuming the specified
    compounded rates of appreciation of the Company's Common Stock over the
    term of the option. Actual gains, if any, on the stock option exercises are
    dependent on the future performance of the Common Stock, overall market
    conditions, as well as the option holders' continued employment through the
    vesting period. The amounts reflected in this table may not necessarily be
    achieved.
(3) With respect to shareholders, the potential realizable value illustrates
    the gain that might be realized on the 57,868,541 shares of Common Stock
    issued and outstanding as of year end, assuming the specified compounded
    rates of appreciation of the Company's Common Stock over the term of the
    options. The value is calculated based on the Exercise or Base Price of the
    option grant on February 3, 1995 of $16.25 per share.

  The Safety-Kleen Pension Plan for Salaried Employees (the "Pension Plan")
provides retirement benefits for life for salaried employees, including
executive officers, of the Company and its participating subsidiaries. Pensions
are based on final pay, which is defined as the average annual earnings
(including commissions and incentive compensation) for the five consecutive
years which yield the highest average. For the named executive officers,
covered compensation is substantially the same as the sum of the Salary and
Bonus columns for 1995 on the Summary Compensation Table. The pensions are
payable monthly commencing the first calendar month after retirement. Various
provisions under the Internal Revenue Code of 1986, as amended (the "Code")
limit the accrued benefit payable under the Pension Plan, currently to
$120,000, and limit the amount of annual compensation that may be taken into
account in determining pension benefits, currently to $150,000.
 
  Under the Safety-Kleen Corp. Excess Benefit Plan (the "Excess Benefit Plan"),
executive officers are generally entitled to the difference between the
benefits actually paid to them under the Pension Plan and the benefits which
they would have received under the Pension Plan were it not for certain
restrictions imposed under the Code, discussed above. The Excess Benefit Plan
also provides that
 
                                       9
<PAGE>
 
the executive officers' benefits are calculated on the highest five of their
last ten years' compensation and that any executive officer who has attained
both the age of 60 years and 30 years of service will receive an unreduced
pension benefit.
 
  The amounts shown above are computed on straight-life annuity amounts and are
not subject to deduction for Social Security benefits or other offset amounts.
The amounts are assumed payable under the Pension Plan option providing
lifetime benefits for the employee only, and would be reduced if the retiree
elected a surviving spouse's pension. Messrs. Johnson, Brinckman, Chalhoub,
Dattilo and Willmschen had 3 years, 36 years, 1 year, 28 years, and 17 years,
respectively, of credited service under the Pension Plan as of December 31,
1995.
 
EMPLOYMENT CONTRACTS AND SEVERANCE ARRANGEMENTS
 
  Two agreements that the Company entered into with Mr. Johnson at the time he
joined the Company expired on January 17, 1996. Under their terms, the Company
had agreed that if Mr. Johnson's employment terminated for any reason other
than gross misconduct during the one year period which ended on January 17,
1996, the Company would (i) continue salary payments for six months and make a
pro rata payment under the Management Incentive Plan, (ii) recommend to the
Board that the vesting of any stock options granted prior to the date of
termination be accelerated, (iii) pay for one move to the East Coast according
to the Company Moving Policy in place at the time and (iv) provide executive
outplacement services to Mr. Johnson.
 
  The Company has entered into agreements with twenty of its officers and other
vice presidents, including the named executive officers, providing for the
payment of certain severance benefits in the event the officer or vice
president is terminated within three years after a change in control of the
Company (which is generally defined as the purchase by any person or group of
persons of more than 20% of the issued and outstanding Common Stock, a change
in the majority of the members of the Board over a 24-month period, or certain
corporate reorganizations) for reasons other than a voluntary termination or
discharge for cause (as both terms are defined in such contracts). Benefits
under these contracts include the payment of a lump sum severance benefit equal
to three times the executive's annual salary at the time of termination (or if
greater, at the time of the change in control), plus three times the greater of
(i) the bonus he received for the previous year or (ii) the maximum bonus to
which he could be entitled for the year in which the termination occurs.
 
  Each of the severance agreements provides for a reduction of payments due
under such agreement, to the extent that such payments, together with all other
amounts payable to the executive other than payments attributable to options
granted him under the Company's stock option plans, constitute "excess
parachute payments" under federal tax law. The contract also provides that the
Company will reimburse the executive for any additional income taxes (including
excise taxes) he incurs as a result of payments upon termination (including
payments attributable to options) being treated as excess parachute payments
under federal income tax law.
 
COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
  Pursuant to the rules regarding disclosures of Company policies concerning
executive compensation, this report is submitted by Messrs. Farmer, Gwillim,
and Jannotta in their capacity as the Board's Compensation Committee and
addresses the Company's compensation policies for 1995 as they affected Mr.
Johnson, the Chief Executive Officer ("CEO"), and the Company's other executive
officers, including the named executive officers.
 
  Overview of Executive Compensation Policy. The Company's compensation
philosophy is incentive oriented, particularly for executive officers. The key
elements of the Company's executive
 
                                       10
<PAGE>
 
compensation program consist of salary, annual bonus, and stock options. The
annual bonus portion of the officers' compensation is incentive based and is
directly linked to corporate performance and returns to shareholders.
Accordingly, the Company has developed an overall compensation strategy and
specific compensation plans that tie a significant portion of executive
compensation to the Company's success in meeting specified performance goals
and to appreciation in the Company's stock price. The overall objectives of
this strategy are to motivate the CEO and the executive officers to achieve the
goals inherent in the Company's business strategy, to link executive and
shareholder interests through equity-based plans, and finally, to provide a
compensation package that recognizes individual contributions, as well as
overall business results.
 
  In determining compensation, the Compensation Committee compares the
executive officers' compensation to the compensation paid to persons in
comparable positions at comparable companies. While the elements of
compensation described below are considered separately, the Compensation
Committee takes into account the full compensation package provided by the
Company to the individual, including pension benefits, supplemental retirement
benefits, severance plans, insurance, and other benefits. The comparable
companies used for this comparison are not the same companies that comprise the
peer group index in the Stock Performance Graph on page 13, because the
Compensation Committee believes that the Company's competitors for executive
talent are not generally the companies included in that index. For these
purposes, comparable companies are approximately 49 companies, surveyed by an
outside consulting firm, whose sales, assets, shareholders' equity, net income,
return on equity, and total number of employees are similar to those of the
Company (the "Primary Survey Group"). For purposes of evaluating compensation
of the CEO and the other named executive officers, the Compensation Committee
also reviews data on a special survey group (the "Special Survey Group"). The
Special Survey Group reports the compensation paid to the named executives
holding comparable positions at publicly traded industrial companies with sales
between $750 million and $1 billion and with earnings between $45 million and
$75 million. For 1995, the Special Survey Group consisted of 26 companies.
 
  In addition, the Compensation Committee receives the recommendations of the
CEO for the compensation to be paid the executive officers, other than the CEO
and the Chairman of the Board. This process is designed to ensure consistency
throughout the executive compensation program.
 
  The Compensation Committee does not believe that IRC Section 162(m), which
denies a deduction for compensation payments in excess of $1 million to the CEO
or a named executive officer, is likely to be applicable to the Company in the
near future, but will reconsider the implications of IRC Section 162(m) if and
when it appears that the section may become applicable.
 
  Salaries. Salaries for executive officers are determined by (i) subjectively
evaluating the responsibilities of the position held and the experience and
performance of the individual and (ii) comparing base salaries for comparable
positions at comparable companies. Salaries paid to the named executive
officers, including Mr. Johnson, in 1995 were below the fiftieth percentile of
the amount paid for comparable positions among the Special Survey Group.
 
  Annual Bonus. The Company's executive officers are eligible for an annual
cash bonus under the Company's Management Incentive Plan (the "Plan"). The
purpose of the Plan is to supplement through an incentive bonus the pay for
executive officers (and other key management personnel) so that overall total
cash compensation (salary and bonus) is externally competitive and properly
rewards Plan participants for their efforts in achieving certain specified pre-
tax earnings goals. If the Company meets these target earnings goals, total
cash compensation (salary and bonus) will be at the seventy-fifth percentile of
the amount paid for comparable positions among the Primary Survey Group.
 
  The Plan operates as follows. In 1995, the return on beginning-of-year equity
("ROE") for each firm comprising the Standard & Poor's 500 is calculated and
arranged in descending ROE order (from
 
                                       11
<PAGE>
 
the 99th percentile on down) for the four consecutive calendar quarters ending
with the third quarter for the preceding year (for 1994, the Standard & Poor's
500 data was for the four consecutive calendar quarters ending with the third
quarter for that year). Each percentile is also matched with its corresponding
ROE. If the Company's ROE, as defined in the Plan, for the year is less than
the ROE level, of the specified, predetermined percentile, then no bonus is
paid. If, however, the Company's ROE equals the minimum ROE level, then a
formula incentive bonus pool of .7% of consolidated pretax earnings, as defined
in the Plan, is created. The size of the formula bonus pool increases on a
graduated basis to a maximum of 5% of consolidated pretax earnings if the
maximum ROE level is attained. Each participant is allocated a percentage of
the bonus pool based on the participant's responsibilities at the Company. At
the beginning of each year, the Compensation Committee reviews the CEO's
recommendations for participants in the Plan and determines the list of Plan
participants and the percentage share of the formula pool for each participant.
For 1995, there were 112 participants in the Plan.
 
  In addition to a share of the formula pool, a Plan participant is also
eligible for a discretionary bonus not to exceed 50% of his or her share of the
formula pool. Thus, the aggregate maximum annual bonus payments would be 7.5%
of pre-tax earnings. After the Company has received its audited year-end
financial statements and the size of the formula bonus pool has been
determined, the Compensation Committee reviews the CEO's recommendations for
each participant's discretionary award based on the participant's individual
contributions to the Company and determines the participant's discretionary
shares. The Plan also provides for the Board of Directors to make a
determination, notwithstanding the other Plan provisions, regarding the amount
of the bonus pool and the awards to be paid to individual participants. This
provision permits the Board of Directors to make whatever changes it deems
necessary to preserve the purposes and objectives of the Plan.
 
  For 1995, a formula pool of 1.85% of pre-tax earnings was allocated to
participants. Discretionary bonuses increased the size of the total pool
allocated to participants to 2.8% of pre-tax earnings. For 1995, Mr. Johnson
received 5.45% of the formula bonus pool under the Plan and a discretionary
bonus equal to 30% of his share of the formula pool.
 
  Stock options. Stock option grants under the 1985 and 1993 Stock Option Plans
are designed to align the long-term interests of the Company's executives and
its shareholders and assist in the retention of executives. Stock options are
granted with an exercise price equal to the market price on the date of grant.
The Company's practice is to award options at the beginning of each year and
vest such options at the rate of 25% per year beginning at the one-year
anniversary of the grant. This approach is designed to create shareholder value
over the long-term because the full benefit of the options cannot be realized
unless stock price appreciation occurs over a number of years.
 
  In February 1995, the Compensation Committee recommended and the Board of
Directors granted nonqualified stock options under the 1993 Stock Option Plan
to all executive officers, as well as certain other employees. The grants made
to each executive officer, including the CEO, were based on each executive's
level in the Company and immediate prior year's total cash compensation. The
number of options granted to each executive officer was determined by (i)
multiplying the executive's total cash compensation by a specified percentage
(which ranged from 150% to 80%) depending upon the executive officer's level of
responsibility within the Company and (ii) dividing the product obtained in (i)
by the Company's average stock price for the prior year. This formula approach,
which is indirectly based on competitive compensation data, provides for awards
based on current duties and responsibilities, as well as present and potential
contributions to the success of the Company.

PROPOSAL 2: APPROVAL OF THE PROPOSED AMENDMENT TO THE 1993 STOCK OPTION PLAN
 
  The Board of Directors of the Company has adopted, subject to approval of the
shareholders, an amendment to the 1993 Stock Option Plan (the "1993 Plan") to
increase the number of shares of Common Stock which may be issued pursuant to
the exercise of options under the 1993 Plan from 2,750,000 shares to 5,250,000
shares.
 
  As of February 28, 1996, options to purchase 924 shares under the 1993 Plan
had been exercised and there were options outstanding to purchase 2,446,245
shares. Thus, as of that date, additional options to purchase 302,831 shares
could be granted under the 1993 Plan. The Board of Directors believes that the
1993 Plan is a key component of the Company's ability to attract and retain key
personnel. The Board considers the amendment to the Plan to be necessary to
provide for future grants over the remaining term of the Plan. Except for the
increase in the number of shares issuable under the 1993 Plan, the amendment
will not affect the other provisions of the 1993 Plan and, in particular, will
not extend its term, which expires on December 31, 2002. A summary of the
material features of the 1993 Plan is set forth below. A copy of the Plan may
be obtained by sending a written request to the Corporate Secretary.
 
  Adoption of the foregoing proposal requires the affirmative vote of a
majority of the shares of Common Stock present or represented, and entitled to
vote at the annual meeting of shareholders.
 
  The Board of Directors recommends that the shareholders vote FOR Proposal 2.
 
TERMS OF THE 1993 PLAN
 
  Options granted under the 1993 Plan may be either incentive options qualified
under Section 422 of the Code ("ISOs") or non qualified options ("NQOs"). The
1993 Plan will be administered by a committee of disinterested members of the
Company's Board of Directors (the "Committee"). The number of shares which may
be issued under the 1993 Plan is subject to adjustment as described below.
 
  The Committee will determine the employees to whom options may be granted,
the number of shares of Common Stock to be covered thereby and the other terms
and provisions of such grant. Employees who are members of the Committee and
Directors of the Company who are not also employees of the Company or any of
its subsidiaries will not be eligible to participate in the 1993 Plan.
Executive officers and other key employees of the Company will be eligible to
participate in the 1993 Plan.
 
  Each option granted pursuant to the 1993 Plan will be evidenced by a stock
option agreement which will state the total number of shares of Common Stock to
which it pertains, the price, the manner and terms of payment (which may
include the delivery of already owned shares of the Company's Common Stock in
payment of the purchase price), the time or times at which such option shall
become exercisable and such other terms and provisions as shall comply with the
1993 Plan. The price at which each share of common stock may be purchased may
not be less than the per share market value on the grant date except if any
person shall become employed by the Company or any of its subsidiaries by
reason of the acquisition by the Company of the business by which such person
was previously employed or if the Company or any subsidiary shall hire a person
who was previously employed by an employer other than the Company or any of its
subsidiaries, then a stock option may be granted to such person having an
aggregate spread at the grant date equal to the aggregate spread (as reasonably
determined by the Committee) on any options granted to such person by such
person's former employer which shall be cancelled or given up by such person in
connection with such acquisition or change of employment.
 
                                       14
<PAGE>
 
  The Committee may grant options that provide that if the grantee delivers
shares to satisfy all or part of the exercise price upon exercise of the
option, such person will automatically be granted a new option entitling the
holder to purchase a number of shares equal to the number of shares delivered
in connection with the exercise of such option at a purchase price equal to the
per share market value on the exercise date of the exercise.
 
  The 1993 Plan contains provisions regarding Limited Stock Appreciation Rights
("LSARs") and Stock Appreciation rights ("SARs"). The LSARs provide that if
there is a Change of Control of the Company, then each person holding an LSAR
will, on exercise of the LSAR, receive a cash payment for the Change of Control
Value of the options held. The Change of Control Value is based upon the
difference between the exercise price of the option and the highest per share
market value of the Company's Common Stock during the 180 days preceding the
exercise of the LSAR or, if greater, the highest price per share paid for the
Common Stock in connection with the Change of Control. The 1993 Plan provides
that unless the Committee otherwise determines, LSARs will automatically be
granted in tandem with stock options granted under the 1993 Plan to officers
who become subject to Section 16 of the Securities Exchange Act of 1934 (the
"'Exchange Act") and that such LSARs will automatically be deemed exercised at
the later of a Change of Control or six months and one day after the grant of
the LSAR. The Committee also has, but to date has not exercised, the authority
to grant SARs which are exercisable even if no Change of Control has occurred
provided that the payment on exercise of such SARs would be equal to the
difference between the exercise price of the related stock option and the
market value of the Company's Common Stock on the date of exercise. LSARs and
SARs may only be granted in tandem with purchase options so that the number of
shares available under the option will be reduced by the number of shares for
which the LSAR or SAR is exercised and vice versa.
 
  Each option granted under the 1993 Plan will expire 10 years after it is
granted (unless the Committee specifies an earlier expiration date). No LSAR or
SAR may be exercised after the expiration of the stock option with respect to
which it was granted. If for any reason any shares remain subject to any LSAR,
SAR or option when it expires, those shares may be used again for options
thereafter granted under the 1993 Plan. In addition, if the holder of any
option satisfies all or part of the purchase price payable upon exercise of the
option by the delivery of shares already owned by the option holder, then the
shares so delivered may be used (in addition to all shares otherwise available
under the 1993 Plan) for options subsequently granted under the 1993 Plan.
 
  The Committee shall adjust the number of shares available and options granted
under the 1993 Plan and the price at which shares may be purchased upon
exercise of such options to reflect stock splits, mergers and other similar
events.
 
  The Board of Directors may at any time terminate the 1993 Plan or make such
changes or amendments as it deems advisable. However, the Board of Directors
may not, without the approval of holders of a majority of the shares of Common
Stock of the Company, increase the number of shares subject to the 1993 Plan
other than to reflect a change in capitalization or lower the minimum exercise
price. If not earlier terminated by the Board of Directors, the 1993 Plan will
terminate on December 31, 2002. No options may be granted under the 1993 Plan
after it terminates, but options granted prior to the termination of the 1993
Plan may be exercised after termination at any time during the option term.
 
  The amount of options to be received by any one employee or class of
employees under the 1993 Plan as amended will be set by the Committee from time
to time in its discretion and therefore is not presently determinable.

                                 OTHER MATTERS
 
  The following proposals have been timely and properly submitted by two of the
Company's shareholders. The proposals were accompanied by supporting statements
and notice by the proponents of their intention to present the proposals for
action at the annual meeting.
 
  Each shareholder proponent must appear personally or by proxy at the annual
meeting to present his proposal for action. Each proposal will be approved if
it is introduced and voted on at the annual meeting and is supported by a
majority of the shares present or represented, and entitled to vote with
respect to the proposal. Each of these proposals is advisory only, so that a
vote in favor of either of the proposals does not guarantee that any particular
action will be taken by the Company respecting the proposal. The Company's
Board of Directors recommends a vote AGAINST each of the following proposals.
If these proposals are presented at the annual meeting and the Company receives
your proxy, it will be voted on the proposals as you specify, or if you do not
specify voting instructions, it will be voted AGAINST each of the shareholder
proposals.
 
PROPOSAL 3: SHAREHOLDER PROPOSAL REGARDING ELIMINATION OF CLASSIFIED BOARD OF
            DIRECTORS
 
  Mr. William Steiner, 4 Radcliff Drive, Great Neck, New York 11024, the owner
of 950 shares of Common Stock, has notified the Company that he intends to
introduce the proposal set forth below for consideration and action by the
shareholders at the annual meeting. The Board of Directors disclaims any
responsibility for the content of the proposal and the proponent's supporting
statement reproduced below.
 
    "RESOLVED, that the stockholders of the Company request that the Board of
  Directors take the necessary steps, in accordance with state law, to
  declassify the Board of Directors so that all directors are elected
  annually, such declassification to be effected in a manner that does not
  affect the unexpired terms of directors previously elected."
 
                              SUPPORTING STATEMENT
 
    "The election of directors is the primary avenue for stockholders to
  influence corporate governance policies and to hold management accountable
  for implementation of those policies. I believe that the classification of
  the Board of Directors, which results in only a portion of the Board being
  elected annually, is not in the best interests of the Company and its
  stockholders.
 
    The Board of Directors of the Company is divided into three classes
  serving staggered three-year terms. I believe that the Company's classified
  Board of Directors maintains the incumbency of the current Board and
  therefore of current management, which in turn limits management's
  accountability to stockholders.
 
    The elimination of the Company's classified Board would require each new
  director to stand for election annually and allow stockholders an
  opportunity to register their views on the performance of the Board
  collectively and each director individually. I believe this is one of the
  best methods available to stockholders to insure that the Company will be
  managed in a manner that is in the best interests of the stockholders.
 
    I am a founding member of the Investors Rights Association of America and
  I believe that concerns expressed by companies with classified boards that
  the annual election of all directors could leave companies without
  experienced directors in the event that all incumbents are voted
  out by stockholders, are unfounded. In my view, in the unlikely event that
  stockholders vote to replace all directors, this decision would express
  stockholder dissatisfaction with the incumbent directors and reflect the
  need for change.
 
    I URGE YOUR SUPPORT. VOTE FOR THIS RESOLUTION."
 
 
                                       16
<PAGE>
 
RECOMMENDATION OF THE BOARD AGAINST SHAREHOLDER PROPOSAL
 
  The supporting statement to this proposal suggests that, by having each
director elected every year, management would be more accountable to
shareholders. The Board of Directors disagrees with this argument for two
reasons. First, the Board believes that this proposal inaccurately suggests
that both the Board itself and management currently are not sufficiently
accountable to shareholders. However, the Company endeavors to respond to
questions and concerns raised by shareholders, and has recently added a
Director of Investor Relations to the corporate staff to assist in this effort.
Moreover, the Company's directors are subject to the same standards of
performance regardless of the term of their service. Thus, the directors
elected to the Board are not less accountable to shareholders merely because
they are not elected annually. Second, because the Board nominates nominees for
directors at each annual meeting, the Board believes that shareholders have an
effective means to communicate their views on the performance of the Board,
regardless of whether all or less than all of the seats on the Board are open
for election.
 
  More significantly, however, the Board believes that there are advantages to
a classified board which the proposal and supporting statement fail to address.
A classified Board of Directors can promote continuity, experience and
stability of leadership by assuring that a majority of the Board of Directors
at any given time will have experience with the business affairs and operations
of the Company. A classified Board also can help the Company to attract and
retain well-qualified individuals to serve as directors by providing such
individuals with sufficient time to understand the Company and to formulate and
implement the policies that they believe will benefit the Company. The Board
believes that the resulting continuity of experience among directors and the
resulting opportunities for farsighted strategic planning promote long-term
success for the Company.
 
  In addition, the Board believes that the interests of long-term shareholders
of the Company can be better protected by a classified board. With a classified
board, a majority of the Board generally cannot be replaced over less than two
annual shareholders' meetings. In the absence of a classified board, it is
possible that a person could in a short period assemble enough votes (which may
not even represent a majority of the outstanding shares) to replace the entire
Board of Directors. By precluding abrupt changes in the composition of the full
Board of Directors, a classified Board of Directors encourages persons who may
seek to gain control of the Company to initiate such actions through arms-
length negotiations with the Board, which can then evaluate all shareholders'
interests.
 
  Finally, the Board believes that stability in the management of the Company
also promotes the interests of shareholders by helping the Company to attract
qualified employees and helping the Company to build long-term relationships
with customers, business partners and other constituencies. Given the highly
competitive nature of the Company's business, the Board believes that these
relationships are essential to the success of the Company.
 
  SUMMARY: For the foregoing reasons, your Board of Directors believes that a
classified board continues to benefit the Company, its shareholders and all
those who do business with the Company by permitting them to rely on the
continuity of, or on reasoned and methodical changes in, the Company's
policies. The shareholders are also assured that the annual elections, in which
some of the members of the Board of Directors are elected each year, provide
them with the opportunity to express their views as to the quality and
responsiveness of the Company's leadership. THE BOARD OF DIRECTORS URGES
SHAREHOLDERS TO VOTE AGAINST THE SHAREHOLDER PROPOSAL REGARDING ELIMINATION OF
CLASSIFIED BOARD OF DIRECTORS.
 
PROPOSAL 4: SHAREHOLDER PROPOSAL REGARDING "GOLDEN PARACHUTES"
 
  Mr. Kenneth Steiner, 14 Stoner Avenue, Suite 2-M, Great Neck, New York 11021,
the owner of 350 shares of Common Stock has notified the Company that he
intends to introduce the proposal set
 
                                       17
<PAGE>
 
forth below for consideration and action by the shareholders at the annual
meeting. The Board of Directors disclaims any responsibility for the content of
the proposal and the proponent's supporting statement that has been reproduced
below.
 
    "RESOLVED, that the shareholders recommend that the board of directors
  adopt a policy against entering into future agreements with officers and
  directors of this corporation which provide compensation contingent on a
  change of control of the corporation, unless such compensation agreements
  are submitted to a vote of the shareholders and approved by a majority of
  shares present and voting on the issue."
 
                              SUPPORTING STATEMENT
 
    "Lucrative severance contracts awarded to senior corporate executives
  which provide compensation contingent on a change of control, usually
  through a merger or acquisition of the corporation, are known as "golden
  parachutes". These contracts are awarded without shareholder approval.
 
    The practice of providing these large cash awards to a small group of
  senior corporate managers without shareholder approval has been a subject
  of public outcry. In 1988, the U.S. Senate in emphasizing the potential
  conflict of interest between management and shareholders created by these
  agreements voted ninety eight to one to require shareholder approval of
  golden parachutes which exceed three times annual compensation.
 
    Although final action was not taken, it is clear to me that the
  overwhelming vote in favor of the measure reflects public sentiment against
  golden parachutes. A shareholder vote would allow the corporation's owners
  to decide for themselves whether golden parachutes are in their best
  interests.
 
    I am a founding member of the Investors Rights Association of America and
  it is clear to me that requiring a shareholder vote is necessary to address
  the conflicts of interest between management and shareholders that arise in
  the awarding of golden parachutes.
 
    I URGE YOUR SUPPORT. VOTE FOR THIS RESOLUTION"
 
RECOMMENDATION OF THE BOARD AGAINST SHAREHOLDER PROPOSAL
 
  Your Board of Directors believes that change of control severance
compensation arrangements are an essential and appropriate element of sound
corporate management and serve the best interests of shareholders. By providing
financial security against loss of employment following a change of control,
these arrangements help management to remain focused in pursuing all
opportunities to increase shareholder value without concern and distraction
over their own financial security and in assessing objectively any takeover
attempt that might arise. Furthermore, the Board believes that the ability to
offer current and prospective officers financial security against loss of
employment following a change of control helps the Company to attract and
retain qualified management personnel. The Board of Directors believes that
requiring shareholder approval of this type of agreement would place the
Company at a disadvantage to other companies with which it competes in hiring
and retaining top employees.
 
  The Board of Directors does not believe that a vote occurring in the late
1980's in one house of Congress on a bill that was not enacted as law should be
relied on by shareholders in determining how to vote on this proposal. Instead,
the Board believes that an evaluation of the agreements that the Company has
with twenty of its officers and vice presidents demonstrates that the Board and
the
Compensation Committee, which is composed entirely of directors who are not
currently and have not in the past been employees of the Company, have
carefully developed change of control severance agreements that should not
result in a windfall bonus to covered employees.
 
                                       18
<PAGE>
 
  It is important to note that under these agreements, no benefit is paid
unless (1) a change of control occurs, and (2) thereafter, the officer's
employment is terminated other than through a voluntary termination by the
officer. Thus, it is an acquiror, and not the covered employee, who controls
whether the severance benefits will be owed. Also, the agreements have no
current cost to the Company or its shareholders.
 
  SUMMARY: For the foregoing reasons, your Board of Directors believes that the
proposal does not articulate a clear reason why the Company and its
shareholders would benefit from implementation of the proposal, and in fact
that the Company could be competitively disadvantaged through implementation of
the proposal. THE BOARD OF DIRECTORS URGES SHAREHOLDERS TO VOTE AGAINST THE
SHAREHOLDER PROPOSAL REGARDING "GOLDEN PARACHUTES."
 
 
      COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE ACT OF 1934
 
  The Company's executive officers and directors are required to file under the
Exchange Act reports of ownership and changes of ownership with the Securities
and Exchange Commission and the New York Stock Exchange.
 
  Based solely on information provided to the Company by executive officers and
directors, the Company believes that during the preceding year all filing
requirements applicable to executive officers and directors have been
satisfied.
 
                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
  In 1987, the Company purchased its oil processing business from enterprises
controlled by Joseph Chalhoub. Mr. Chalhoub is now a Senior Vice President of
the Company and supervises, among other things, the Company's oil reprocessing
business. Mr. Chalhoub holds a 31% interest in Booth Oil Company, Inc.
("Booth"). Booth is the operator of an oil reprocessing facility in Buffalo,
New York which is owned by the Company (the "Facility"). The Company paid Booth
approximately $2.7 million for processing services at the Facility during 1995.
The Company believes that the prices it paid for processing and management
services at the Facility were competitive with the prices it would have been
required to pay at other third party facilities. The Company also paid Booth
$142,000 in July, 1995 for a boiler and certain other equipment which Booth had
purchased for $142,000.
 
  During 1995, the Company paid approximately $118,000 to Williams & Vanino,
Inc., for environmental management consulting services. Marcia E. Williams, a
director of the Company, is President of Williams & Vanino. In addition, Marcia
Williams' husband is a partner with the law firm of Latham & Watkins. Safety-
Kleen paid approximately $426,000 to Latham & Watkins for legal services in
1995. Latham & Watkins' total revenues in 1995 were over $299 million.
 
                         INDEPENDENT PUBLIC ACCOUNTANTS
 
  The Board of Directors has appointed Arthur Andersen LLP, independent public
accountants, as auditors for its fiscal year ending December 28, 1996, upon the
recommendation of its Audit Committee.
 
  The firm of Arthur Andersen LLP has audited the accounts of the Company since
1968. A representative of the firm of Arthur Andersen LLP will be in attendance
at the shareholders' meeting with the opportunity to make a statement if such
representative desires to do so and will be available to respond to shareholder
questions.

                   AS AMENDED AND RESTATED MAY 10, 1996

                       
                       (SUBJECT TO SHAREHOLDER APPROVAL)

                      SAFETY-KLEEN 1993 STOCK OPTION PLAN



PART 1.  PURPOSE

     The purpose of this Plan is to promote the long-term financial interests of
the Company and its subsidiaries by (i) providing an incentive which the Company
may use to induce able persons to enter into or remain in the employment of the
company or one of its subsidiaries, (ii) providing employees with an additional
incentive to promote the Company's financial success and (iii) furthering the
identity of interests of participants with those of the shareholders of the
Company.

     This Plan shall be administered by a Committee composed of Company
directors appointed as prescribed in Part 11 of this Plan.

     Certain terms used in this Plan have the meaning indicated for such terms
in Section 12.1 of this Plan.


PART 2.  PERSONS ELIGIBLE TO RECEIVE OPTIONS

     A person shall be eligible to be granted an option under this Plan only if
(i) on the proposed Grant Date for such option or at some time between the Grant
Date of such option and the exercise of such option, such person shall be
employed either by the Company or by a subsidiary, and (ii) such person is not a
member of the Committee. A person eligible to be granted an option under this
Plan is herein called an "eligible employee". A director of the Company who is
not also such an employee of the Company or a subsidiary shall not be eligible
to receive options under this Plan.


PART 3.  STOCK OPTIONS

     Section 3.1  Power to Grant Options. The Committee shall have the right and
the power to grant at any time to any eligible employee an option entitling such
person to purchase shares from the Company in such quantity, at such price, on
such terms and subject to such conditions consistent with the provisions of this
Plan as may be established by the Committee on or prior to the Grant Date for
such option. Each option to purchase shares which shall be granted by the
Committee pursuant to the provisions of this Part 3 is herein called a "stock
option" and an "option".

     Section 3.2  Purchase Price.

          (a)  General Rule.  Except as otherwise provided in this Section 3.2,
     the price at which each share may be purchased upon exercise of any option
     granted under this Plan may not be less than the per share market value on
     the Grant Date for such option.

          (b)  Special Rule for New Employee.  If any person shall become
     employed by the Company or a subsidiary by reason of the acquisition by the
     Company of the business by which such person was previously employed or if
     the Company or any subsidiary shall hire a person who was previously
     employed by an employer other than the Company or a subsidiary, then an SAR
     and/or nonqualified option may be granted to such person having an
     aggregate spread at the Grant Date not greater than the aggregate spread
     (as reasonably determined by the Committee) on any options granted to such
     person by such person's former employer which shall be cancelled or given
     up by such person in connection with such acquisition or change of
     employment. In connection with any SAR or nonqualified option granted
     pursuant to the preceding sentence, the Committee shall have the power to
     determine the number of shares subject to such SAR and/or nonqualified
     option and to establish an exercise price which will result in an aggregate
     spread on the Grant Date not greater than the aggregate spread permitted by
     the preceding sentence. The "aggregate spread" on any particular option
     shall be determined by multiplying the number of shares subject to the
     option (including shares not yet vested or otherwise available for
     purchase) times the amount by which the per share market value of the
     shares subject to the option on the date as of which the aggregate spread
     is being determined shall exceed the exercise price of such option.

                                       2
<PAGE>
 
     Section 3.3  Option Terms. The Committee shall have the power to determine
the eligible employees to whom options shall be granted under this Plan, the
number of shares to be subject to each option, the number of options to be
awarded to each eligible employee and the time at which each option under this
Plan shall be granted.  Except as otherwise expressly provided in this Plan, the
Committee shall also have the power to determine, at the time of the grant of
each option, all terms and conditions governing the rights and obligations of
the holder with respect to such option, including but not limited to: (i) the
exercise price per share or the method by which the exercise price per share
shall be determined (provided that the price shall not in any case be less than
the price permitted by Section 3.2); (ii) the length of the period during which
the option may be exercised and any vesting requirements or other limitations on
the number of shares purchasable with the option at any given time during such
period; (iii) the times at which the option may be exercised; (iv) any
conditions precedent to be satisfied before the option may be exercised; (v) any
restrictions on resale of any shares purchased upon exercise of the option; and
(vi) whether or not such option will constitute an incentive stock option under
Section 422 of the Internal Revenue Code (or any successor provision).  The
terms "nonqualified option" and "NQO" when used in this Plan mean an option
granted under this Plan which is not an incentive stock option.

     Section 3.4  ISO Requirements.  No person may be granted incentive stock
options under this Plan in any year entitling such person to purchase a number
of shares greater than the maximum number permitted by Section 422 of the
Internal Revenue Code (or any successor provision).  An option granted under
this Plan shall not be an incentive stock option unless the terms of the option
agreement evidencing such option shall explicitly state that it is intended to
be an incentive stock option.

     Section 3.5  Automatic Grants.  The Committee shall have the right to grant
any option under this Plan with a feature providing that if the original grantee
delivers shares to satisfy all or part of the exercise price upon exercise of
the option (the "exercised option"), the original grantee shall automatically be
granted a new option with a Grant Date on the exercise date of the exercised
option entitling the option holder to purchase a number of shares equal to the
number of shares delivered in connection with the exercise of the exercised
option at a purchase price equal to the per share market value on the exercise
date of the exercised option and having such other terms and conditions as the
Committee shall specify in the agreement granting the exercised option at the
time the exercised option was granted.


PART 4.  STOCK APPRECIATION RIGHTS

     Section 4.1  Power to Grant Stock Appreciation Rights.  The Committee shall
have the right and the power to grant to the holder of any stock option granted
under this Plan (the "tandem option") a right to elect to receive an amount
equal to the spread on that option (determined as of the time of the exercise of
such right) times the number of eligible shares chosen by the option holder at
the time of exercise and/or a right to receive the Per Share Change of Control
Value for the shares subject to the tandem option (determined as prescribed in
Section 4.5) in the event a Change of Control shall occur (determined as
pescribed in Section 4.7).  Each right granted pursuant to this Part 4 shall be
deemed a "Stock Appreciation Right" or "SAR". The Committee shall have the right
in connection with the grant of any SAR under this Plan to impose such
conditions and limitations on its exercise as the Committee shall choose.
Unless the Committee or this Plan shall otherwise specify, each SAR shall be
subject to all conditions on exercise imposed with respect to the tandem option.
The term "eligible shares" as applied with respect to any particular SAR at any
particular time shall mean the shares subject to the related tandem option which
the option holder is entitled to purchase at the particular time and with
respect to which the related SAR is exercisable at the particular time under
such terms and conditions as the Committee may have specified at the time of the
grant of the related SAR.

     Section 4.2  Tandem Requirement.  The exercise of any SAR granted under
this Plan shall reduce the number of eligible shares which shall be available
for purchase under the tandem option by the number of shares for which the SAR
shall be exercised.  Conversely, the exercise of any option shall reduce the
number of shares for which any SAR granted in connection with such option (the
"tandem SAR") may be exercised by the number of shares for which the option
shall be exercised.

     Section 4.3  Time of Grant.  An SAR may be granted simultaneously with the
grant of the stock option with which it is associated or may be granted at any
time after the 

                                       3
<PAGE>
 
grant of such option.  In no event may an SAR be exercised after
the tandem option with which it is associated ceases to be exercisable.

     Section 4.4  Limited Stock Appreciation Rights.  Without limiting the
generality of the preceding provisions, the Committee shall have the authority
to grant any SAR with the following characteristic:

          (a)  the SAR shall automatically be converted into cash in the amount
     of the Change of Control Value (determined as prescribed in Section 4.5) on
     the date (the "Auto Exercise Date") which shall occur on the later of (i)
     the date of the Change of Control or (ii) six months and one day after the
     Grant Date of the SAR;

          (b)  the related tandem stock option shall be terminated immediately
     after such conversion; and

          (c)  the SAR shall not be exercisable except as provided in clause
     (a).

An SAR with all three characteristics specified in the preceding sentence shall
be deemed to be a "Limited Stock Appreciation Right" or "LSAR".  Any agreement
under this Plan which grants a Limited Stock Appreciation Right shall be
understood to grant a right having the three characteristics specified in the
first sentence in this Section 4.4.  Unless the Committee shall prescribe a
different result, at the time any eligible employee becomes subject to the
provisions of Section 16 of the Securities Exchange Act of 1934 with respect to
the Company's Common Stock, such eligible employee shall automatically be
granted at that time an LSAR for every stock option then held by such person
under this Plan which shall not previously have had a tandem LSAR associated
with it.

     Section 4.5  Change of Control Value.  The Company shall pay the holder of
any LSAR within three days after the  Auto Exercise Date cash in the amount of
the Change of Control Value of that LSAR calculated as of the Auto Exercise Date
in accordance with this Section 4.5.  The Change of Control Value of any
particular LSAR shall be an amount determined by multiplying (i) the Change of
Control Spread (determined as provided in the next sentence as of the Auto
Exercise Date) times (ii) the number of shares subject to the related tandem
option on the particular date (before giving effect to the termination of that
stock option pursuant to clause (b) in Section 4.4) including shares not yet
then vested or which (absent this provision) would not be available for purchase
under the tandem option on the particular date.  The Change of Control Spread on
any particular date shall be equal to the greater of zero or the remainder
derived by subtracting (i) the exercise price of the tandem stock option with
respect to which such SAR was issued from (ii) the Per Share Change of Control
Value on the Auto Exercise Date (determined as provided in the next sentence).
"Per Share Change of Control Value" as used in this Plan or an agreement made
pursuant to this Plan means the highest per share market value during the period
beginning on the 180th day before the particular date as of which Per Share
Change of Control Value shall be determined and ending on the day preceding that
particular date or, if greater, the highest price per share of Common Stock paid
in connection with the Change of Control.

     Section 4.6  Permitted SAR Terms.  The Committee is authorized to grant any
Stock Appreciation Right (i) which entitles the holder to receive the Change of
Control Spread upon exercise of the SAR (subject to such terms and conditions as
the Committee may prescribe under the terms of grant), (ii) which is not subject
to the limitation prescribed in clause (c) of Section 4.4, and (iii) which shall
have such other terms and conditions not prohibited by this Plan which the
Committee shall elect to prescribe at the time of the grant of such SAR.

     Section 4.7  Definition of Change of Control.  When used in this Plan or an
agreement granting an option under this Plan, the term "Change of Control" shall
mean any of the following with respect to the Company:

          (i) any person or group (other than a subsidiary corporation as
     defined in Section 425(f) of the Code with the Company being treated as the
     employer corporation for purposes of determining subsidiary status or any
     employee benefit plan (or any related trust) of the Company or such a
     subsidiary) becomes the beneficial owner of 20% or more of either the then
     outstanding Common Stock or the combined voting power of the then
     outstanding voting securities of the Company entitled to vote generally in
     the election of directors, except that (A) no such person or group shall be
     deemed to own beneficially any securities acquired directly from the
     Company pursuant to a written agreement with the Company unless 

                                       4
<PAGE>
 
     such person or group subsequently becomes the beneficial owner of
     additional Common Stock or voting securities of the Company other than
     pursuant to a written agreement with the Company and (B) no Change of
     Control shall be deemed to have occurred solely by reason of any such
     acquisition by a corporation with respect to which, after such acquisition,
     more than 60% of both the then outstanding common shares of such
     corporation and the combined voting power of the then outstanding voting
     securities of such corporation entitled to vote generally in the election
     of directors are then beneficially owned, directly or indirectly, by the
     persons who were the beneficial owners of the Common Stock and voting
     securities of the Company immediately before such acquisition in
     substantially the same proportion as their ownership, immediately before
     such acquisition, of the then outstanding Common Stock and the combined
     voting power of the then outstanding voting securities of the Company
     entitled to vote generally in the election of directors, as the case may
     be;

          (ii) individuals, who, as of January 1, 1993, constitute the Board of
     Directors (the "Incumbent Directors") cease for any reason to constitute at
     least a majority of the Board of Directors; provided that any individual
     who becomes a director after January 1, 1993 whose election, or nomination
     for election by the Company's stockholders, was approved by a vote or
     written consent of at least two-thirds of the directors then comprising the
     Incumbent Directors shall be considered as though such individual were an
     Incumbent Director, but excluding, for this purpose, any such individual
     whose initial assumption of office is in connection with an actual or
     threatened election contest relating to the election of the directors of
     the Company (as such terms are used in Rule 14a-11 under the Securities
     Exchange Act of 1934, as amended); or

          (iii) approval by the stockholders of the Company of (A) a merger,
     reorganization or consolidation with respect to which the individuals and
     entities who were the respective beneficial owners of the Common Stock and
     voting securities of the Company immediately before such merger,
     reorganization or consolidation do not, immediately after such merger,
     reorganization or consolidation, beneficially own, directly or indirectly,
     more than 60% of respectively, the then outstanding common shares and the
     combined voting power of the then outstanding voting securities entitled to
     vote generally in the election of directors of the corporation resulting
     from such merger, reorganization or consolidation, (B) a liquidation or
     dissolution of the Company or (C) the sale or other disposition of all or
     substantially all of the assets of the Company.


PART 5.  TERMS APPLICABLE TO ALL OPTIONS AND SARS GRANTED UNDER THIS PLAN.

     Section 5.1  Common Terms.  Unless the context of this Plan clearly
otherwise requires, the requirements applicable to any stock option granted
under this Plan shall also apply to any tandem SAR granted with respect to that
option.

     Section 5.2  Option Agreement.  No person shall have any rights under any
SAR and/or option granted under this Plan unless and until the Company and the
person to whom such SAR and/or option shall have been granted shall have
executed and delivered an agreement expressly granting the SAR and/or option to
such person and containing provisions setting forth the terms of the SAR and/or
option.

     Section 5.3  Grant Date.  An SAR or option shall be deemed to have been
granted under this Plan on the date (herein called the "Grant Date") designated
by the Committee (either specifically or by means of a mechanism for determining
such date) at the time it shall approve such SAR or option, provided that the
Committee may not designate a Grant Date with respect to any option which shall
be earlier than the date on which the granting of such option shall have been
approved by the Committee and may not designate a Grant Date for any SAR which
is earlier than the Grant Date of the relevant tandem option.

     Section 5.4  Ten Year Maximum Term.  No option or SAR granted under this
Plan may be exercised on or after the tenth anniversary of its Grant Date.  No
SAR granted under this Plan may be exercised after the termination date for the
related tandem option with respect to which the SAR was granted.

     Section 5.5  Modification of Option After Grant.  Each option and SAR
granted under this Plan may be modified after the date of its grant by express
agreement between 

                                       5
<PAGE>
 
the Company and its holder provided that any such change (i) shall not be
inconsistent with the terms of this Plan and (ii) shall be approved by the
Committee.

     Section 5.6  Limitations on Transfer.  No option or SAR granted under this
Plan shall be transferable otherwise than by will or the laws of descent and
distribution, and any option or SAR granted under this Plan may be exercised
during the lifetime of the person to whom the option shall initially have been
granted only by the original grantee.

     Section 5.7  Taxes.  The Company shall be entitled, if the Committee deems
it necessary or desirable, to withhold (or secure payment from the option holder
in lieu of withholding) the amount of any withholding or other tax due from the
Company with respect to any amount payable and/or shares issuable under any
option or SAR granted under this Plan, and the Company may defer such payment or
issuance unless indemnified to its satisfaction against any liability for any
such tax.

     Section 5.8  No Right to Employment Conferred.  Nothing in this Plan or (in
the absence of any express provision to the contrary) in any option or SAR
granted pursuant to this Plan, shall confer on any person any rights to continue
in the employment of the Company or any subsidiary or interfere in any way with
the right of the Company or any subsidiary to terminate such person's employment
at any time.


PART 6.  EXERCISE PROCEDURES

     Section 6.l  Exercise Notice.  Each option and SAR granted under this Plan
shall be deemed exercised on the date (the "exercise date") the Company's
Secretary (or other person designated by the Company's Chief Financial Officer)
shall receive written notice of such exercise signed by the option holder and in
a form reasonably satisfactory to the Committee or shall receive other notice of
exercise satisfactory to the Committee.  An option holder shall not have any
rights with respect to shares issuable under any option granted under this Plan
by reason of such option until the exercise of that option with respect to those
shares.

     Section 6.2  Payment of Exercise Price.  The exercise price of shares
purchased upon the exercise of an option granted under this Plan shall be paid
in full in cash by the option holder at the time of the delivery of such shares
provided that the Committee (or any person or persons to whom the Committee
shall delegate the authority) may (but need not) permit payment to be made by
delivery to the Company of either (i) shares, or (ii) any combination of cash
and shares permitted by the Committee (or any such person or persons).  In the
event any shares shall be transferred to the Company to satisfy all or any part
of the exercise price, the part of the exercise price deemed to have been
satisfied by such transfer of shares shall be equal to the product derived by
multiplying the per share market value as of the date of exercise times the
number of shares transferred.  Unless the Board shall otherwise determine, any
shares transferred to the Company as payment of all or part of the purchase
price upon the exercise of any option granted under this Plan shall be utilized
as soon as possible to supply the shares deliverable by reason of the subsequent
exercise of options under this Plan.


PART 7.  OPTION TERM AND VESTING

     Section 7.l  Normal Option Term.  Except as otherwise provided in this Plan
or the agreement evidencing any SAR and/or option granted under this Plan, the
right to exercise any option or SAR granted under this Plan shall terminate at
whichever of the following times shall earlier occur:  (i) three months after
the employment termination date of the original grantee or (ii) the specified
expiration date of the option or SAR.

     Section 7.2  Extension of Exercise Time.  The Committee in its sole
discretion shall have the right (but shall not in any case be obligated) to
permit any option or SAR granted under this Plan to be exercised more than three
months after the employment termination date of the original grantee or after
the specified expiration date specified in the agreement granting such option or
SAR, provided that the Committee shall not have the right to permit exercise of
any option or SAR on or after the tenth anniversary of its Grant Date or to
permit exercise of an SAR after the termination date of the related tandem
option.

     Section 7.3  Normal Rule: No Vesting After Employment Termination Date.
After an original grantee's employment termination date, the number of shares
for which any option or SAR may be exercised shall not increase (pursuant to
vesting or other provisions in 

                                       6
<PAGE>
 
such option or SAR) but rather shall be limited to the number of shares for such
option or SAR could have been exercised immediately prior to the employment
termination date provided that: (i) the Committee shall have the right to waive
this restriction in whole or in part either at the time such option or SAR is
granted or at any later time and (ii) this restriction shall not apply when a
different result is prescribed by Section 7.4, Section 7.5 or Part 9.

     Section 7.4  Acceleration of Vesting.

          (a)  Discretionary Acceleration.  The Committee in its sole discretion
     shall have the right (but shall not in any case be obligated)(i) to permit
     purchase of shares under any option prior to the time such shares shall be
     purchasable under the terms of the agreement granting such option, and/or
     (ii) to permit exercise of an SAR prior to the time such SAR shall be
     exercisable under the terms of the agreement granting such SAR.

          (b)  Automatic Acceleration Upon Change of Control.  Upon the
     occurrence of a Change of Control, every option and SAR outstanding under
     the Plan at the time of the occurrence of such Change of Control shall be
     accelerated and may thereafter be exercised with respect to all shares
     subject to such option or SAR.

     Section 7.5  Retirement, Disability and Death.

          (a)  Special Definitions

          Career Termination - If an individual's employment with the Company
          and its subsidiaries terminates because of the individual's retirement
          (as defined in this Section 7.5(a)), Qualified Disability (as defined
          in this Section 7.5(a)), or death, then such termination shall be
          deemed a "Career Termination" and the individual shall be deemed a
          "Career Participant."

          Post-Career Benefits - The term "Post-Career Benefits" as applied with
          respect to any particular option means the rights under that option
          which exist solely because of rights arising under this Section 7.5.

          Post-Career Option - Every option or SAR held by a Career Participant
          in the capacity of original grantee which has a termination date after
          the Career Participant's Career Termination shall be deemed a "Post-
          Career Option" for purposes of this Plan.

          Qualified Disability - The term "Qualified Disability" means an
          injury, disease or disability which the committee shall determine (i)
          to be the primary cause of the termination of employment of the
          original grantee of any SAR and/or option and (ii) should entitle the
          holder of the SAR and/or option to the Post-Career Benefits.

          Retirement - An individual shall be deemed to retire on the date he or
          she ceases to be employed by the Company or any of its subsidiaries if
          on that date the individual is at least 55 years of age and has been
          employed by the Company and/or its subsidiaries for at least five
          years and if the cessation of employment is not caused by death or a
          Qualified Disability.

          (b)  Vesting Adjustments.  Except as otherwise provided in Section
     7.5(d), during the period between the Career Termination of the original
     grantee of any Post-Career Option and the termination date of that option,
     any shares subject to that option which shall not have been vested at the
     Career Termination shall vest at the time(s) and in the numbers they would
     have vested if the original grantee's employment termination date had not
     occurred.

          (c)  Termination Date Extension.  Except as otherwise provided in
     Section 7.5(d) or Section 7.6, the termination date for each Post-Career
     Option held by any Career Participant in the capacity of original grantee
     will be the earlier of (i) the fifth anniversary of his or her Career
     Termination or (ii) the specified expiration date of that option.

          (d)  Exceptions.

               (1)  Death.  Except as may otherwise be provided pursuant to
          Section 7.5(d)(2):

                                       7
<PAGE>
 
                    (A)  In the event a Career Participant dies, then (except as
               provided in the next two sentences), the termination date for any
               Post Career option granted to the decedent in the capacity of
               original grantee shall be the later of (i) the termination date
               otherwise established under or pursuant to this Plan or (ii) the
               first anniversary of the death.  The preceding sentence shall not
               be effective to extend the termination date for any option or SAR
               for which the termination date shall have occurred prior to the
               death.  If the effect of the first sentence of this paragraph (A)
               would be to extend the termination date of any option or SAR
               beyond the day prior to the tenth anniversary of the granting
               date of the option (or the relevant tandem option), then the
               termination date shall be the day prior to such tenth
               anniversary.

                    (B)  In the event a Career Termination is caused by death,
               then all vesting restrictions in each of the Post-Career Options
               held by the decedent in the capacity of original grantee shall
               cease to apply upon the decedent's death and the holder of that
               Option shall be entitled to exercise that Option with respect to
               any or all of the shares subject to that Option at any time from
               the Career Termination until the termination date of that option.

               (2)  Modification on Grant.  The Committee shall have the right
          at the time of grant of any option or SAR to omit Post-Career Benefits
          from that option or SAR altogether or to provide benefits with respect
          to that option or SAR which are different from those prescribed in
          this Section 7.5.  The Post-Career Benefits prescribed in this Section
          7.5 shall apply only to the extent they do not conflict with the
          express terms specified at the time of the grant of any option or SAR
          (including terms contained in the agreement evidencing that option or
          SAR).

               (3)  Modification Immediately After Retirement.  The Committee in
          its sole discretion shall have the right to determine that the holder
          of any particular Post-Career Option should not be entitled after
          retirement of the relevant original grantee to Post Career Benefits
          under that option, provided that (i) such right may only be exercised
          if the Committee elects to exercise such right and notifies the option
          holder of such exercise within three months after the original
          grantee's retirement and (ii) such right may be exercised only if the
          relevant Career Termination is caused by retirement and may not be
          exercised if the relevant Career Termination is caused by death.  If
          the Committee shall exercise this right, then (i) the termination date
          of the particular Post-Career Option shall be three months after the
          Committee gives the option holder notice of its determination (or such
          later date as the Committee shall adopt as part of its determination)
          and (ii) the option holder shall not have the right to exercise the
          option for any shares which were not vested under the option
          immediately prior to the original grantee's retirement.

     Section 7.6  Noncompete Limitations.  If the Committee shall determine that
the original grantee or the holder of any particular SAR and/or option has
competed with the Company or any of its subsidiaries or has engaged in activity
which the Committee determines to be detrimental to the best interests or
reputation of the Company or any of its subsidiaries, then the Committee shall
have the right to set the termination date of the SAR and/or option for such
date as the Committee in its sole discretion deems appropriate (including a date
prior to the time of such determination) provided that such right may not be
exercised (i) to render any exercise of any option or SAR ineffective (or
otherwise diminish the rights of the option holder with respect to that
exercise) after the Company shall have issued the shares and/or other
consideration issuable by reason of such exercise or (ii) after any Change in
Control.  The Committee shall have the sole discretion to make any determination
under this Section 7.6 and any such determination shall be binding upon all
persons concerned.


PART 8.  SHARES SUBJECT TO THIS PLAN

     Section 8.l  Basic Rule.  Except as otherwise provided in Part 9, the
options and SARs granted under this Plan shall be limited so that at any
particular time, the result of the following shall never exceed 5,250,000
shares:

                                       8
<PAGE>
 
          (i)  all shares which shall have been purchased at or prior to the
     particular time upon the exercise of options at any time granted under this
     Plan, plus

          (ii)  all shares for which payment shall be made at or prior to the
     particular time by reason of exercise of SARs at any time granted under
     this Plan, plus

          (iii)  all shares which may be purchased after the particular time
     under options granted under this Plan outstanding at the particular time,
     minus

          (iv)  the number of shares which shall have been delivered to the
     Company at or prior to the particular time to pay the exercise price of
     options exercised at or prior to the particular time (and all shares cited
     in this clause (iv) are called "payment shares").

In the event any Option or SAR at any time granted under this Plan shall
terminate before it shall have been fully exercised, then all shares formerly
subject to such option and the tandem SAR (if any) as to which neither the
option nor the Tandem SAR (if any) shall be exercised shall be available for any
SAR and/or option subsequently granted in accordance with the provisions of this
Plan.  The shares sold by the Company under this Plan may be either unissued
shares or treasury shares.

     Section 8.2  Limitations on Payment Shares.  Payment shares shall not be
used for any option (a "Section 16 option") granted to a person who on the Grant
Date is subject to the reporting requirements imposed by Section 16 of the
Securities Exchange Act of 1934.  Unless the Committee expressly prescribes a
different result, payment shares received by the Company under this Plan shall
be deemed to be used for the first options granted under this Plan after receipt
of those payment shares which are not Section 16 options.


PART 9.  ADJUSTMENTS TO REFLECT CAPITAL CHANGES

     Section 9.1  Stock Splits.  The number of shares subject to outstanding
options and SARs, the number of shares which subsequently become available for
purchase under any vesting provisions in options or SARs outstanding under this
Plan, the exercise price for which shares may be purchased upon the exercise of
outstanding options, the exercise price for shares covered by outstanding SARs
and the number of shares available for options and SARs subsequently granted
under this Plan shall be appropriately adjusted to reflect any stock dividend,
stock split, or other action determined by the Committee to be similar to any of
the actions expressly indicated in this sentence in its substantive effect upon
this Plan or the options or SARs granted under this Plan.

     Section 9.2  Changes in Capitalization.  In the event of any
reorganization, recapitalization, reclassification, merger, consolidation or
sale of all or substantially all of the Company's assets followed by liquidation
or other transaction which is effected in such a way that holders of Common
Stock are entitled to receive securities or other assets with respect to or in
exchange for Common Stock (a "Capital Change"), the Committee shall make
appropriate changes to assure that each outstanding option thereafter represents
the right to acquire, in lieu of or in addition to the shares of Common Stock
subject to such option, such securities or assets which the holder of such
option would have received if all shares subject to such option had been owned
by such holder at the record date for such Capital Change by reason of such
ownership.  In connection with a Capital Change, the Committee shall make such
changes in each SAR as the Committee determines appropriate to reflect such
Capital Change.  The Board of Directors shall have the right to make such
changes in the kind of securities or other property available for options and
SARs granted under this Plan as the Board deems appropriate to reflect such
Capital Change.  Unless the Committee shall otherwise determine, a cash
distribution on the Company's Common Stock shall not constitute a Capital Change
for purposes of this Plan.

     Section 9.3  Final Determinations.  The determination of the Committee or
the Board as to the nature of the adjustment to be made in response to any event
contemplated by this Part 9 shall be binding upon all persons concerned.

     Section 10.1 Amendment.  Except as provided in this Section, the Board
shall have complete power and authority to amend this Plan at any time and no
approval by the Company's shareholders or by any other person, committee or
other entity of any kind shall be required to make any amendment approved by the
Board of Directors effective.  The Board shall not, however, do any of the
following without the affirmative approval of the Company's shareholders: (i)
increase the maximum number of shares available for options and SARs granted
under this Plan except as provided in Part 9; or (ii) lower the minimum exercise
price permitted by this Plan for any option or SAR granted under this Plan
except as provided in Part 9.  No termination or amendment of this Plan may,
without the consent of the individual to whom any SAR and/or option shall
theretofore have been granted under this Plan, adversely affect the rights of
such individual under such SAR and/or option.

     Section 10.2  Termination.  The Board of Directors shall have the right and
the power to terminate this Plan at any time.  If this Plan is not earlier
terminated, this Plan shall terminate on December 31, 2002.  No options shall be
granted under this Plan after termination of this Plan, but the termination of
this Plan shall not have any other effect and any option or SAR outstanding at
the time of the termination of this Plan may be exercised after termination of
this Plan at any time prior to the termination date of such option or SAR to the
same extent such option or SAR would have been exercisable had this Plan not
terminated.


PART 11.  ADMINISTRATION OF THE PLAN

     Section 11.1  Committee's Powers.  This Plan shall be administered by a
committee (herein called the "Committee") designated by the Company's Board of
Directors in accordance with the provisions of Section 11.2.  The Committee
shall have full power and authority to prescribe, amend and rescind rules and
procedures governing administration of this Plan.  Each action of the Committee
which shall be within the scope of the authority delegated to the Committee by
this Plan or by the Company's Board of Directors shall be binding on all
persons.

     Section 11.2  Committee Membership.  The Board shall have the power to
appoint and remove members of the Committee provided that each member shall be a
director of the Company who is disinterested for purposes of Rule 16b-3 as
issued under the Securities Exchange Act of 1934.  A person's membership on the
Committee shall automatically cease when such person ceases to be a director of
the Company or ceases to be disinterested.  At any time at which no special
Committee shall have been constituted by the Board especially for the purposes
of this Plan, all disinterested members of the Compensation Committee
established pursuant to the Company's By-Laws shall have all powers and rights
delegated to the "Committee" under this Plan.

     Section 11.3  Committee Action.  Unless the Board or the Committee shall
expressly decide to the contrary, a majority of the members of the Committee
shall constitute a quorum and any action taken by a majority of the Committee
members at a meeting at which a quorum is present shall be deemed an act of the
Committee.  No member of the Committee shall be liable for any action or
omission relating to his or her service on the Committee.
