                                PROXY STATEMENT
 
     This statement is furnished in connection with the Annual Meeting of
Stockholders of MAPCO Inc. (the "Company") to be held at 10:00 a.m., Central
Daylight Time, May 25, 1994 at the offices of the Company, 1800 South Baltimore
Avenue, Tulsa, Oklahoma 74119.
 
     Stockholders of record at the close of business on April 4, 1994 will be
entitled to vote at the meeting.
 
                            SOLICITATION OF PROXIES
 
     Execution and return of the enclosed proxy, which may be revoked at any
time prior to the meeting, is being solicited by and on behalf of the Board of
Directors of the Company for the purposes set forth in the foregoing notice of
meeting.
 
     Solicitation other than by mail may be made personally, by telephone or by
telegraph, by regularly employed officers and employees of the Company who will
not be additionally compensated therefor. The Company will request persons, such
as brokers, nominees and fiduciaries, holding stock in their names for others,
or holding stock for others who have the right to give voting instructions, to
forward proxy material to their principals and request authority for the
execution of the proxy and will reimburse such persons for their expenses in so
doing. D. F. King & Co., Inc. has been retained to assist in the solicitation of
proxies at a cost not expected to exceed $15,000. The total cost of soliciting
proxies will be borne by the Company. All shares represented by valid proxies
will be voted, absent contrary instructions.
 
                               VOTING SECURITIES
 
     Each Stockholder is entitled to one vote for each share of Common Stock,
$1.00 par value ("Common Stock"), registered in his name on the Company's books
at the close of business on April 4, 1994. The Company has no other voting
securities outstanding. Stockholders do not have cumulative voting rights in the
election of Directors. Other than the election of Directors, the approval of
each proposal that is being submitted to the Stockholders requires the
affirmative vote of a majority of the votes cast at the meeting. Directors are
elected by a plurality of the votes of the shares present in person or
represented by proxy at the meeting and entitled to vote on the election of
Directors. Although abstentions and broker non-votes will be included in the
calculation of the number of shares that are considered present at the Annual
Meeting, they will not be counted as votes cast. As of April 4, 1994, the record
date for voting, there were 29,964,822 shares of Common Stock of the Company
outstanding and entitled to vote.

                             ELECTION OF DIRECTORS
 
     The Board of Directors is divided into three classes with the terms of
office of the Directors of each class ending in different years. After the
Annual Meeting of Stockholders for which this Proxy Statement has been prepared,
the Class I, II and III Directors are to serve until the Annual Meeting of
Stockholders in 1995, 1996 and 1997, respectively, or until their successors are
elected.
 
     Class III nominees for election as director were considered at the
Nominating Committee meeting held on January 25, 1994. It was unanimously
approved that Herman J. Schmidt, Malcolm T. Hopkins and Donald Paul Hodel be
nominated for election as Class III Directors at this Annual Meeting of
Stockholders. All of the nominees are currently serving as Directors. Each of
the nominees has consented to nomination and will serve as a Director if
elected. If any of the nominees should be unable to serve, which is not
anticipated, proxies will either be voted for the election of a substitute
nominee or the number of Directors will be accordingly reduced by action of the
Board of Directors. During 1993, MAPCO Inc. did not add or lose any board
member. There are currently no vacancies on the Board of Directors.
 
           COMMON STOCK OWNERSHIP OF DIRECTORS AND EXECUTIVE OFFICERS
 
     The following tabulation provides information as to each person nominated
for election as a Director and each of the other Directors whose term of office
will continue after the meeting. The table also shows information concerning

and by the Company's Chief Executive Officer, each of the Company's four other

               MEETINGS, COMMITTEES AND COMPENSATION OF THE BOARD
 
     During 1993, six meetings of the Board of Directors were held. The Board
has established four committees to assist it in the discharge of its
responsibilities. The principal functions of each committee are described in the
succeeding paragraphs.
 
                              EXECUTIVE COMMITTEE
 
     The Executive Committee has and may exercise all the powers of the Board of
Directors except to (1) elect Directors, (2) alter, amend or repeal the
Company's By-laws, (3) declare any dividend or make any other distribution to
the Stockholders of the Company, (4) appoint any member of any Board Committee
or (5) authorize any merger or consolidation, or sale, lease or encumbrance of
all or substantially all the assets of the Company, or any acquisition by the
Company of all or substantially all of the business or assets of any other
corporation or entity. The Committee did not meet in 1993. The Committee members
are James E. Barnes (Chairman), Wayne K. Goettsche, Robert M. Howe, Robert L.
Parker and Herman J. Schmidt.
 
                                AUDIT COMMITTEE
 
     The Audit Committee's functions are (1) to recommend to the Board of
Directors, subject to stockholder approval, the selection of the Company's
independent auditors, (2) on behalf of the Board of Directors to oversee the
Company's financial reporting process, (3) to review and discuss with the
internal auditor and the independent auditors, the overall scope and specific
plans for their respective audits, (4) to review and discuss with the internal
auditor and independent auditors the results of their examinations, their
evaluations of the Company's internal controls, and their assessments of the
overall quality of the Company's financial reporting, and (5) such additional
duties as may be assigned by the Board of Directors. This Committee had five
meetings during 1993. The Committee members are Wayne K. Goettsche (Chairman),
Harry A. Fischer, Jr., Philip C. Lauinger, Jr. and Donald Paul Hodel.
 
                             COMPENSATION COMMITTEE
 
     At its March 1994 meeting, the Compensation Committee duties were revised
by the Board of Directors. Currently, the Compensation Committee's functions are
to (1) approve the salaries of all Executive Officers (those officers with
reporting obligations under Section 16 of the Securities and Exchange Act of
1934, as amended), (2) designate participants, establish objectives, establish
applicable performance measurement criteria and make awards under all executive
incentive compensation plans, including stock-based plans, (3) review summary
data of annual segment incentive compensation plans, (4) establish the Company's
overall compensation philosophy and annual merit budget guidelines and monitor
the appropriateness and consistency of the Company's compensation practices,
goals, policies and philosophies, (5) review from time to time data prepared by
third party consultants to gauge the appropriateness and competitiveness of
compensation and benefits for executive personnel, (6) review from time to time
the level and composition of all elements of compensation, benefits and
perquisites provided to non-employee members of the Board of Directors, (7)
amend and oversee the administration of health plans and qualified and
non-qualified benefit plans, including approving all contributions to profit
sharing plans, and delegate to the management of the Company limited authority
to amend benefit plans, (8) evaluate the performance of the Chief Executive
Officer ("CEO") and other Executive Officers and counsel the CEO in management
development and
 
                                        7
<PAGE>   11
 
performance evaluation matters, (9) assure that effective succession planning is
conducted for the CEO and other Executive Officers, (10) review and approve
compensation and benefit information to be included in the Company's annual
proxy statement and prepare, over the names of the Committee members, the
"Compensation Committee Report on Executive Compensation" on an annual basis for
the Company's proxy statement, and (11) recommend to the Board of Directors for
final approval: the adoption of health plans and qualified and non-qualified
benefit plans and the adoption and amendment of executive incentive compensation
and stock-based plans, the adoption and amendment of compensation and benefit
plans and programs for non-employee members of the Board of Directors and
employment continuation agreements or similar agreements proposed to be entered
into with any executive. This Committee had five meetings during 1993. The
Committee members are Herman J. Schmidt (Chairman), Malcolm T. Hopkins, Donald
L. Mellish, Robert L. Parker and Samuel F. Segnar.
 
                              NOMINATING COMMITTEE
 
     The Nominating Committee's functions are to recommend candidates for
membership on the Board of Directors and to recommend the duties and makeup of
the committees of the Board of Directors. To be considered for inclusion in the
slate of nominees proposed by the Board of Directors at the next annual meeting,
such recommendations, including the nominees' qualifications and consent, should
be sent to the Committee in care of the Secretary of the Company and received no
later than December 31, 1994. The Committee had three meetings in 1993. The
current Committee members are Donald L. Mellish (Chairman), Robert L. Parker,
Herman J. Schmidt and Samuel F. Segnar.
 
                           COMPENSATION OF THE BOARD
 
     Employee directors are not compensated for services as a director.
Non-employee directors ("Outside Directors") receive an annual retainer of
$25,000 and, with the exception of director Donald L. Mellish, a fee of $1,000
for attendance at each Board or Committee meeting. Because Mr. Mellish routinely
travels to Board or Committee meetings from outside the contiguous 48 states, he
receives double the Board or Committee meeting attendance fee of $1,000;
provided, however, if the Board and Committee meetings are held jointly, only
his Board attendance fee is doubled. Until March 1993, under the MAPCO Inc. 1989
Outside Director Stock Option Plan, described below, an Outside Director was
able to elect to receive discounted stock options in lieu of all or half of his
annual retainer fee. This feature was unanimously eliminated by the Board on
March 24, 1993. The Audit and Compensation Committee Chairmen receive additional
annual compensation of $4,000 and the Nominating Committee Chairman receives
annual compensation of $3,000 in addition to Committee attendance fees. The
Company also reimburses its Directors for travel, lodging and related expenses
incurred in attending Board and Committee meetings and provides each Outside
Director with $100,000 in life insurance benefits and $250,000 in accidental
death and dismemberment insurance benefits.
 
     Outside Directors are eligible to participate in the 1986 Retirement Plan
for Non-Employee Directors (the "Director Retirement Plan"). Under the Director
Retirement Plan, an Outside Director who has completed at least five years of
service as a member of the Board of Directors and retires from the Board after
attaining age 70 will receive a benefit for life equal to the annual retainer
fee payable to Outside Directors at the time of his retirement. An Outside
Director who has not attained age 70 at the time he leaves the Board, but who
has completed at least five years of service as a member of the Board, will
generally receive a benefit equal to the annual retainer fee then payable to
Outside Directors for the lesser of (i) the number of years during which the
Outside Director served as a member of the Board or (ii) ten years. Upon the
occurrence of a Change in Control (as defined in the Employment Continuation
Agreements for executive officers described below), all Outside Directors will
be entitled to receive a benefit under such plan, regardless of the length of
Board membership. Such benefit will be equal to the annual retainer fee then
payable to Outside Directors multiplied by the greater of (i) the number of
years during which the Outside Director served as a member of the Board or (ii)
ten years.

1989 OUTSIDE DIRECTOR STOCK OPTION PLAN
 
     In 1989, the Company, with the approval of the Stockholders, adopted the
1989 Outside Director Stock Option Plan (the "Director Plan"). All Outside
Directors are eligible to participate in the Director Plan. There are currently
nine Outside Directors.
 
     The maximum number of shares of the Company's Common Stock that may be
issued under the Director Plan is 200,000. In the event of a stock split or a
stock dividend or other relevant change affecting the Company's Common Stock,
appropriate adjustments may be made in the number of shares that could be issued
in the future and in the number of shares and price of all outstanding options
granted before such event. If an option is cancelled or expires without the
issuance of shares, the shares subject to such option will be available for
future grants under the Director Plan.
 
     Annual Grants. In each calendar year during the term of the Director Plan,
each Outside Director will receive an immediately exercisable option having a
ten-year term to purchase 2,000 shares of the Company's Common Stock. Each such
annual award shall be made on the later of the first business day following the
annual meeting of the Company's Stockholders or June 1 and shall have an option
price equal to the fair market value of a share of the Company's Common Stock on
the date of grant.
 
     Termination of Board Membership. In the event that an Outside Director's
Board membership terminates by reason of retirement after attaining age 70,
long-term disability or death, such Director's options may thereafter be
exercised in full in the case of retirement for a period of three years and in
the case of death or disability for a period of one year, subject in each case
to the stated term of the option. In the event an Outside Director's Board
membership terminates for any other reason, such Director's options will expire.
 
     Other Information. The Board may terminate or suspend the Director Plan at
any time but such termination or suspension shall not affect any options then
outstanding. Unless sooner terminated by action of the Board, the Director Plan
will terminate on March 29, 1999, but options outstanding on such date shall
continue to be outstanding until the expiration of their terms. The Board may
also amend the Director Plan as it deems advisable, but unless the Stockholders
approve, no such amendment may materially increase the benefits to Outside
Directors. In addition, no such amendment shall adversely affect any option
theretofore granted under the Director Plan without the holder's consent.
 
                             EXECUTIVE COMPENSATION
 
     The following table sets forth the total compensation paid or accrued by
the Company for services provided during the fiscal years ended December 31,
1993, 1992 and 1991 to the Chief Executive Officer and the four other most
highly compensated executive officers (the "named Executive Officers") whose
total cash compensation for the year ended December 31, 1993, exceeded $100,000.

(1) Senior level executive officers of the Company waived bonuses for 1992.
 
(2) Represents tax gross-up payments to a nonqualified defined contribution
    plan.
 
(3) Under the 1989 Stock Incentive Plan, MAPCO has a "reload" or replacement
    option feature providing for additional options to restore the potential
    future appreciation of any outstanding shares actually used to exercise an
    option, as well as shares forfeited for tax withholding ("Replacement
    Option"). Replacement Options are granted only in connection with
    stock-for-stock exchanges where an optionee exercises vested stock options
    with already-owned stock of the Company. The Replacement Options which are
    received by the optionee are equal to the number of shares used to exercise
    the original options plus those shares forfeited for tax withholding.
    Replacement Options have terms substantially similar to the original
    option, including the same expiration date; however, Replacement Options
    have an exercise price per share equal to the fair market value of a share
    of common stock on the date the Replacement Options are granted.
    Replacement Options are not exercisable for at least six months from the
    grant date for those granted prior to January 22, 1992 and 12 months for
    those granted after January 22, 1992. By recapturing the potential for
    future appreciation through Replacement Options, key management is provided
    with the incentive to acquire shares rather than hold options until the end
    of the exercise period. Replacement Options are granted only to the extent
    existing shares held by the employee are exchanged to exercise options and
    accordingly the total number of options granted never exceeds Stockholder-
    approved limits under stock option plans. The CEO has set stock ownership
    targets for each key member of management including the named Executive
    Officers. The Replacement Option program has encouraged stock option
    exercises and helped to increase stock ownership of key management. The
    Replacement Option feature is also discussed below in the Compensation
    Committee Report on Executive Compensation.
 
(4) All Other Compensation includes Company matching contributions to the MAPCO
    Inc. & Subsidiaries Profit Sharing and Savings Plan (PSSP) and compensation
    paid to or on behalf of the named Executive Officers participating in a
    nonqualified defined contribution plan. Company matching contributions to
    the PSSP for 1993 on behalf of Messrs. Barnes, Howe, Hart, Dickerson and
    Bowman were $18,895, $18,967, $19,228, $19,255, and $19,255, respectively.
    Compensation was paid to or on behalf of Messrs. Barnes, Howe and Hart of
    $25,887, $7,300 and $1,597, respectively, for participation in a
    nonqualified defined contribution plan.

            COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
     The Compensation Committee of the Board of Directors (the "Committee") is
comprised entirely of independent outside directors. The Committee is
responsible for establishing and administering the Company's executive
compensation programs.
 
COMPENSATION PHILOSOPHY
 
     The Committee's compensation philosophy is designed to support the
Company's primary objective of creating value for Stockholders. The Committee
believes that the following compensation strategies for the Executive Officers
achieve this objective:
 
     - Attract and retain talented employees -- The Company provides core
       compensation in the form of base salary and benefit programs that are
       comparable to those of peer companies (described below) and
       similarly-sized domestic general industry companies. The base salary
       target is generally established at the 50th percentile of peer company
       and general industry survey results. For higher levels of responsibility,
       the base salary component is a diminishing portion of the executive's
       potential total compensation.
 
                                       12
<PAGE>   16
 
     - Emphasize pay for performance -- The annual incentive compensation
       program establishes a significant relationship between current Company
       performance and incentive compensation, with substantial rewards possible
       for exceptional results and no reward for poor results.
 
     - Encourage management stock ownership -- The Committee firmly believes
       that long-term Stockholder value will be significantly enhanced by
       management stock ownership. As a result, the Company's stock option
       program strongly encourages stock ownership by the Executive Officers.
 
     Recent federal tax legislation imposes, for 1994 and future years, a
limitation on the deduction for certain Executive Officer compensation in excess
of $1 million subject to certain exceptions. The Committee is currently studying
how it will address the impact of the deduction limit on annual incentive
compensation in excess of $1 million. The Company's stock option program
currently qualifies for exemption from the deduction limit under the IRS
transition rules, and the Committee intends to take such action as is necessary
to maintain such exempt status.
 
     The following are descriptions of the Company compensation programs for the
Executive Officers including the CEO.
 
BASE SALARY
 
     The Company generally establishes base salary ranges by considering peer
company and general industry information. The base salary targets are typically
set at the 50th percentile of this information.
 
     Peer companies, for compensation purposes, are those identified with the
assistance of outside consultants as having fairly comparable size and business
activities to that of the Company. These peer companies are not necessarily
included in the S&P Energy Composite Index used in the performance graph,
captioned "Comparison of Five-Year Cumulative Total Return," shown below. The
principal reason the Company utilizes different companies for performance
comparisons and compensation comparisons is that the sample used in compensation
comparisons is much smaller and more regionalized than that used by the
published indices for performance comparisons. The Company competes for
executive talent mainly in the region where the Company is located and therefore
salary comparisons are more focused.
 
     The base salary of each Executive Officer is reviewed periodically by his
immediate supervisor (or the Committee, in the case of the CEO) resulting in
salary actions typically every 12 to 15 months or longer. The Executive
Officer's position, individual performance, level of responsibility, years with
the Company and the peer company and general industry information described
above are weighed in determining any appropriate salary adjustment. The
Committee reviews and approves all proposed salary adjustments for the Executive
Officers as recommended by the CEO.
 
ANNUAL INCENTIVE AWARDS
 
     Annual incentive awards are available to the Executive Officers to
recognize and reward desired performance. Each year the Compensation Committee
approves the participants, the performance measures and the specific financial
targets. The usual performance measures were replaced by a single measure for
1993 based on Net Cash from Operations. The financial target was discretionarily
set at a level substantially above the target approved by the Board of Directors
in the 1993 Five-Year Operating Plan.
 
     An Executive Officer's target award level is directly dependent upon the
individual's position, level of responsibility and ability to impact the
Company's financial success. Additionally, peer company and general industry
information is reviewed periodically to determine competitive target award
levels. Annual incentive awards for 1993 were directly related to overall
corporate and business unit performance. The awards for 1993 reflect the
Company's performance for 1993 in the area of Net Cash from Operations. Records
were set in the areas of Earnings Per Share, Operating Profit, Funds Provided By
Operations and Cash Per Share.
 
                                       13
<PAGE>   17
 
LONG-TERM INCENTIVE PROGRAM
 
     The Company's current long-term incentive compensation program is limited
to stock options designed to align management interests with those of
Stockholders. In furtherance of this objective, nonqualified stock options were
granted in 1993, with the exercise price equal to the market price on the date
of grant.
 
     After a lengthy vesting period, stock options only have value if the price
of the Company's stock has appreciated in value from the date the stock options
were granted. Obviously, Stockholders also benefit from such stock price
appreciation.
 
     The Company's stock option program is designed to encourage early exercise
of options and retention of the issued stock, by including a reload option
feature ("Replacement Option") and by the CEO establishing a target level of
stock ownership for each Executive Officer in order to encourage a long-term
ownership perspective. The replacement option feature provides for a new option
for each share of Company stock tendered to satisfy an option exercise price.
The replacement option, granted at an exercise price equal to the then current
market price, is for the number of shares exchanged to exercise the original
options, plus shares withheld for taxes, and is exercisable for the remainder of
the original option term. As a result of this design, early exercise and
ownership is encouraged, but stock option recipients can never obtain more
shares of stock than represented by the original option grants.
 
     The level of stock option grants for Executive Officers and other employees
is determined by the Committee each year in consultation with the CEO. A
potential option gain target is identified for groups of employees by
considering their responsibilities, their base salary level and peer company and
general industry long-term compensation information. The number of options to be
awarded is then derived by using a projected stock value that is approved by the
Committee. The Company's awards are typically well above the 50th percentile of
peer company and general industry levels.
 
     The Company is required to purchase shares in the open market equivalent to
the number of shares issued under the stock option program.
 
     Since institution of the replacement option program and stock ownership
targets in 1990, current Executive Officer stock ownership has increased by 490%
to a total of 438,732 shares.
 
CEO COMPENSATION
 
     Mr. Barnes' compensation for 1993 consisted of the same three components
described above for the Executive Officers: base salary, annual incentive
compensation and stock options (in addition to participation in the benefit
programs). The 1993 base salary level for Mr. Barnes was frozen at his ending
1992 level due to a Company-wide salary freeze. The 1992 base salary range was
determined by considering peer company and general industry information. His
base salary was established within the salary range by reference to his
performance and years of service, in addition to peer company and general
industry information. The Committee took into account the fact that Mr. Barnes
has been CEO of MAPCO since 1984 and, during that time period, total Stockholder
return (stock price appreciation and dividends) has averaged 24% per year.
 
     Mr. Barnes' incentive award for 1993 was determined in the same manner as
described above. In particular, the Committee took into account his leading role
in the successful turnaround of the Company's performance in 1993 from a
lackluster 1992.
 
     Pursuant to the stock option program described above, Mr. Barnes was
granted 59,000 nonqualified stock options in 1993.

     The Pension Table above shows approximate total retirement benefits
(expressed as an annual straight-life annuity) based on employment with the
Company for an employee covered by the qualified and nonqualified retirement
plans. "Average annual compensation" is determined with reference to the base
salary and bonus compensation disclosed in the Summary Compensation Table,
except as described below for Messrs. Barnes and Howe. Average annual
compensation levels are the average base salary and bonus compensation for the
three highest consecutive years of the 10 years immediately before retirement
date. The normal retirement date is at age 65, 66 or 67, depending upon the
participant's birth year. The benefit amounts listed in the table are not
subject to reduction for Social Security benefits or on any other basis except
as noted below.
 
     At December 31, 1993 Messrs. Barnes, Howe, Hart, Dickerson and Bowman were
credited with 10.58, 9.08, 14.17, 6.65 and 6.72 years of service, respectively.
 
     In addition, Messrs. Barnes and Howe are, pursuant to separate retirement
agreements, credited with additional service equal to service earned with their
prior employer (26 and 20 years, respectively). Such service is applied with
reference to a modified base salary and bonus compensation at the Company which
reflects only 50% of their promotion pay increases and bonus compensation. This
additional retirement benefit is reduced by the retirement benefit earned by
Messrs. Barnes and Howe at their prior employer. On December 3, 1993, the Board
of Directors approved an amendment to the retirement agreement of Mr. Howe to
provide for vesting of benefits thereunder effective as of December 31, 1993.
Retirement benefits under the supplemental retirement agreement would have
vested on December 1, 1994; however, by accelerating vesting into the calendar
year 1993, both the Company and Mr. Howe avoided increased tax liability which
would have been incurred in 1994 under the Omnibus Budget Reconciliation Act of
1993.
 
EMPLOYMENT CONTINUATION AGREEMENTS
 
     The Company has entered into Employment Continuation Agreements (the
"Agreements") with 12 of its executive officers (the "Officers"), including
Messrs. Barnes, Howe, Hart, Dickerson and Bowman. The Agreements replaced
similar agreements which expired on December 31, 1989. The Agreements were
automatically extended on January 1, 1993, and will continue to automatically
extend each January 1 thereafter unless, not later than October 1 of the
preceding year, the Company shall have given notice that it does not wish to
extend the Agreement and provided that if a Change in Control (as defined below)
occurs, the Agreements shall automatically continue for twenty-four months
beyond the month in which such Change in Control occurred. Under each Agreement,
the Officer is obligated to remain in the Company's employ for the earliest of
(a) nine months following the occurrence of a Potential Change in Control, (b)
the date of a Change in Control, (c) the date the Officer terminates his
employment by reason of Death, Disability or Retirement, or (d) the termination
by the Company of the Officer's employment.
 
     For purposes of the Agreements, a "Change in Control" shall be deemed to
have occurred if (i) any "person," as such term is used in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")
(other than the Company, any trustee or other fiduciary holding securities under
an employee benefit plan of the Company, or any corporation owned, directly or
indirectly, by the Stockholders of the Company in substantially the same
proportion as their ownership of stock of the Company), is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of securities of the Company representing 25% or more of the
combined voting power of the Company's then outstanding securities eligible to
vote; or (ii) during any period of two consecutive years (not including any
period prior to the execution of the Agreement), individuals who at the
beginning of such period constitute the Board, and any new director (other than
a director designated by a person who has entered into an agreement with the
Company to effect a transaction described in clause (i), (ii) or (iv) of this
Paragraph) whose election by the Board or nomination for election by the
Company's Stockholders was approved by a vote of at least two-thirds ( 2/3) of
the directors then still in office who either were directors at the beginning of
the period or whose election or nomination for election was previously so
approved (hereinafter referred to as "Continuing Directors"), cease for any
reason to constitute at least a majority thereof; or (iii) the Stockholders of
the Company approve a merger or consolidation of the Company with any other
corporation, other than a merger or consolidation which would result in the
voting securities of the Company outstanding
 
                                       16
<PAGE>   20
 
immediately prior thereto continuing to represent (either by remaining
outstanding or by being converted into voting securities of the surviving
entity) in combination with the ownership of any trustee or other fiduciary
holding securities under an employee benefit plan of the Company, more than 75%
of the combined voting power of the voting securities of the Company or such
surviving entity outstanding immediately after such merger or consolidation;
provided, however, that a merger or consolidation effected to implement a
recapitalization of the Company (or similar transaction) in which no "person"
(as hereinabove defined) acquires more than 50% of the combined voting power of
the Company's then outstanding securities shall not constitute a Change in
Control of the Company; or (iv) the stockholders of the Company approve a plan
of complete liquidation of the Company or an agreement for the sale or
disposition by the Company of all or substantially all of the Company's assets
(or any transaction having a similar effect).
 
     For purposes of the Agreements, a "Potential Change in Control" shall be
deemed to have occurred if (i) the Company enters into an agreement, the
consummation of which would result in the occurrence of a Change in Control;
(ii) any person (including the Company) publicly announces an intention to take
or to consider taking actions which if consummated would constitute a Change in
Control; or (iii) any person other than a trustee or other fiduciary holding
securities under an employee benefit plan of the Company (or a corporation
owned, directly or indirectly by the Stockholders of the Company in
substantially the same proportion as their ownership of stock of the Company),
who is or becomes the beneficial owner, directly or indirectly, of securities of
the corporation representing 10% or more of the combined voting power of the
Company's then outstanding securities, increases such person's beneficial
ownership of such securities by 5% or more over the percentage so owned by such
person on the date hereof; or (iv) the Board of Directors of the Company adopts
a resolution to the effect that, for purposes of the Agreement, a Potential
Change in Control has occurred.
 
     If, within two (2) years following a Change in Control, an Officer's
employment is terminated by the Company (other than for cause, as defined in the
Agreements, or on account of the Officer's Death, or Disability) or by the
Officer for other than Good Reason as defined in the Agreement, the Company will
pay the Officer the following amounts (the "Severance Payment"):
 
          (a) A single sum payment equal to the product of three (3) times the
     sum of (i) the Officer's then current annual salary, plus (ii) the highest
     annual incentive compensation payment for the current calendar year or any
     of the last three (3) years, plus (iii) awards paid under the Company's
     Performance Bonus Plan or any successor thereto;
 
          (b) A single sum cash payment equal to the product of (x) and (y)
     where (x) equals the difference between (1) the closing price per share of
     the Company's Common Stock on the New York Stock Exchange Consolidated Tape
     (the "NYSECT") on the day immediately prior to the Change in Control of the
     Company and (2) the lowest closing price per share of the Company's Common
     Stock on the NYSECT on any day during the 60-day calendar day period
     immediately preceding the Change in Control of the Company and where (y)
     equals three (3) times the highest number of shares of the Company's Common
     Stock subject to any stock option granted to the Officer within 24 months
     of the Change in Control of the Company;
 
          (c) All reasonable and appropriate legal fees and expenses incurred by
     the Officer as a result of such termination (including all such fees and
     expenses, if any, reasonably incurred in contesting or disputing by
     arbitration or otherwise, any such termination or in seeking to obtain or
     enforce any right or benefit provided by the Agreement or in connection
     with any tax audit or proceeding to the extent attributable to the
     application of Section 4999 of the Internal Revenue Code of 1986, as
     amended, (the "Code"), to any payment or benefit provided under the
     Agreement); and
 
          (d) For a thirty-six (36) month period after the Date of Termination,
     the Company shall provide the Officer with benefits substantially similar
     to those which the Officer was receiving or entitled to receive under the
     Company's life, disability, accident and group health insurance plans or
     any similar plans in which the Officer was participating immediately prior
     to the Date of Termination at a cost to the Officer which is no greater
     than that cost to the Officer in effect at the Date of Termination.

          (e) In addition to the retirement benefits to which the Officer is
     entitled under the Supplemental Executive Retirement Plan ("SERP") and the
     Long-Term Incentive Plan ("LIP") or any successor plan thereto, the Company
     shall pay a single sum amount, in cash, equal to the actuarial equivalent
     of the excess of (x) over (y) where (x) is the amount of the retirement
     pension (determined as a straight-life annuity commencing at Normal
     Retirement Age as defined in the MAPCO Pension Plan) which the Officer
     would have accrued under the terms of the SERP (without regard to any
     amendment to the SERP made subsequent to a Change in Control and on or
     prior to the Date of Termination, which amendment adversely affects in any
     manner the computation of retirement benefits thereunder), determined as if
     the Officer were fully vested thereunder and had accumulated (after the
     Date of Termination) thirty-six (36) additional months of service credit
     thereunder at the Officer's highest annual rate of compensation during the
     twelve (12) months immediately preceding the Date of Termination, and where
     (y) is the amount of any vested retirement pension (determined as a
     straight-life annuity commencing at Normal Retirement Age) which the
     Officer had then accrued pursuant to the provisions of the SERP.
 
          (f) In addition to the retirement benefit the Officer is entitled to
     under the MAPCO Inc. and Subsidiaries Profit Sharing and Savings Plan, the
     Company shall pay the Officer a single sum amount, in cash, equal to
     eighteen percent (18%) times the Officer's highest annual rate of
     compensation during the twelve (12) months immediately preceding the
     Officer's Date of Termination.
 
     The Company has also agreed to pay the Officer an additional amount
("Gross-Up Payment") such that the net amount retained by the Officer upon the
payments provided under the Agreement, after deduction of federal, state and
local income tax and any tax imposed by Section 4999 of the Internal Revenue
Code of 1986, as amended (up to 20%), shall be equal to the Severance Payment.
 
     On January 31, 1990, the Board of Directors of the Company approved
amendments to the Employment Continuation Agreements of the executive officers.
The Amendments provide that in the event of termination following a Change in
Control, the benefits under the Company's SERP shall be determined as of the
earliest possible retirement date using actuarial equivalents as defined in the
Amendments.
 
     In addition to this change, Amendments to Employment Continuation
Agreements of Messrs. Barnes and Howe clarify that in the event of termination
following a Change in Control (1) retirement benefits, including that payable
under Supplemental Retirement Agreements ("SRA"), are calculated based upon the
earliest permitted retirement date and (2) SRA benefits are payable in a single
sum based upon actuarial equivalents, as defined in the Amendments. An
additional amendment to the Employment Continuation Agreements of Messrs. Barnes
and Howe was entered into in 1991 to coordinate changes made in supplemental
retirement agreements as discussed above.
 
                 APPROVAL OF SELECTION OF INDEPENDENT AUDITORS
 
     Upon the recommendation of the Audit Committee, the Board of Directors has,
by resolution, selected Deloitte & Touche, independent auditors to audit the
books, records and accounts of the Company and its subsidiaries for the fiscal
year ending December 31, 1994. Accordingly, this selection is being presented to
the Stockholders for approval at this Annual Meeting.
 
     The firm of Deloitte & Touche has audited the Company's books annually
since 1969, has offices in or convenient to the localities where the Company or
its subsidiaries operate and is considered to be well qualified. If the
Stockholders do not approve the selection of Deloitte & Touche, the selection of
independent auditors will be reconsidered by the Board of Directors.
 
     Audit services performed by Deloitte & Touche during 1993 included
examinations of the Consolidated Financial Statements of the Company and its
subsidiaries, limited reviews of interim financial information, services related
to filings with the Securities and Exchange Commission, and consultations on
matters related to accounting, financial reporting, taxation and general
business advice.

of Stockholders at which time they will have an opportunity to make a statement

     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR THE APPROVAL OF
DELOITTE & TOUCHE TO AUDIT THE COMPANY'S BOOKS.
