1989 INCENTIVE STOCK OPTION PLAN
                    OF EMPIRE GAS ACQUISITION CORPORATION

1.          PURPOSE
            This incentive stock option plan (hereinafter called "Plan") is to
encourage ownership of common shares of Empire Gas Acquisition Corporation
(herein referred to as the "Company") by present or future officers and key
employees of the Company.  This plan is intended to provide an incentive for
maximum effort in the successful operation of the Company and is expected to
benefit the shareholders by enabling the Company to attract and retain the most
talented personnel through opportunity to share, through the proprietary
interests created by this Plan, in increased value of the Company's shares to
which such personnel have contributed.  It is further intended that options
issued pursuant to this Plan shall constitute incentive stock options within the
meaning of Section 422A of the Internal Revenue Code of 1986 (the "Code") and
may be granted to employees of the Company and its subsidiaries as that term is
defined in Section 425(f) of the Code or such other section as may apply to
define employees eligible to participate in plans eligible for Section 422A
treatment.

            The Plan is intended to take the place of the 1983 Incentive Stock
Option Plan of Empire Incorporated (the "1983 Plan").  The terms of the Plan are
a continuation of the 1983 Plan, modified to reflect the establishment of Empire
Gas



Acquisition Corporation.  By reason of the corporate transactions (as defined in
Treas. Reg. Section 1.425-1(a)(1)(ii)) involving Empire Incorporated, Empire Gas
Acquisition Corporation, and parents or subsidiaries thereof, if any, Empire Gas
Acquisition Corporation will assume any options granted under the 1983 Plan.
Any options issued under the 1983 Plan and assumed as provided herein are
intended to comply with the requirements of Section 425(a) of the Code and shall
be interpreted in accordance with that intent.

2.          STOCK

            The stock reserved for issue upon the exercise of options granted
under this Plan will not exceed 600,000 common shares of the Company which may
be either authorized and unissued shares or issued shares held in or hereafter
acquired for the treasury of the Company.  Shares subject to any option under
this Plan which is not exercised in full prior to its expiration or shares as to
which the right to purchase is forfeited through default or otherwise shall
again become available for other options under this Plan.

3.          ADMINISTRATION

            This Plan will be administered by a stock option committee
(hereinafter referred to as "Committee") which shall include not less than two
directors of the Company, none of whom shall be eligible to participate in this
Plan, in addition to

                                    - 2 -


such other persons as may be designated, all of whom shall be appointed by and
serve at the pleasure of the Board of Directors.

            A majority of the Committee shall constitute a quorum, and acts of a
majority fo the members present at any meeting at which a quorum is present, or
acts approved in writing by a majority of the Committee, shall be deemed the
acts of the Committee.

            The Committee shall select one of its members as Chairman.  The
Committee shall appoint a Secretary, who shall maintain a record of its actions,
decisions, and proceedings.  The Committee shall have the authority to grant
options, and:

                        (1)   Determine the number of shares subject to each
                              option and the terms thereof;

                        (2)   Prescribe rules and regulations from time to time
                              for administration of this Plan;

                        (3)   Decide any questions arising as to the
                              interpretation or application of any provision of
                              this Plan; and

                        (4)   Make such other determinations and take such other
                              action as it deems necessary or advisable except
                              as otherwise

                                    - 3 -


                              expressly reserved to the Board in the Plan.

No member of the Board of Directors or the Committee shall be liable for any
action or determination made in good faith with respect to the Plan or any
option granted under it.  Any interpretation, determination, or other action
made or taken by the Committee shall be final, binding, and conclusive except as
otherwise specifically provided in the Plan.

4.          ELIGIBILITY

            An option may be granted to any officer or key employee who at the
 time the option is granted is an employee of the Company as defined in the
In its determination of an employee to whom an option shall be granted and the
number of shares to be covered by such option, the Committee shall take into
account the duties of the employee, the present and potential contributions of
the employee to the success of the Company, the length of tenure and amount of
remuneration of the employee, and other factors deemed relevant by the Committee
in connection with accomplishing the purpose of this Plan.  No employee who owns
(with applicable attribution rules as set forth in the Code) stock possessing
more than ten percent (10%) of the total combined voting power of all classes of
stock of the Company (or its parent or subsidiaries, if any) may be granted an
option under this Plan, unless at the time the option is granted the option
price is at least one hundred ten percent (110%) of

                                    - 4 -


the fair market value of the stock subject to the option and such option by its
terms is not exercisable after the expiration of five (5) years from the date
such option is granted.  The holder of an option hereunder shall have none of
the rights of a shareholder with respect to any of the shares of stock subject
to such option until such shares have been actually issued to him upon the
exercise of such option.

5.          OPTION PRICE

            Each option shall state the option price, which shall be not less
than one hundred percent (100%) of the fair market value of the shares of common
stock of the Company on the date of the granting of the option.  The fair market
value per share shall be determined by the Committee.

6.          GRANT LIMITATION

            Subject to PART 5, the Board of Directors and the Committee, in
fixing the option price, shall have full authority and discretion and be fully
protected in so doing, as long as the aggregate fair market value (determined as
of the time the option is granted) of the stock for which any employee may be
granted incentive stock options in any calendar year prior to January 1, 1987
(under all incentive stock option plans of the Company, its parent or
subsidiaries, if any) shall not exceed one hundred thousand dollars ($100,000),
plus any unused limit carryover to such year, as defined in Section 422A(c)(4)
of the Code.  Options

                                    - 5 -


granted prior to January 1, 1987, and thus subject to the above set out Grant
Limitation, will not be taken into account in applying the Exercise Limitation
as set out in Part 7.

7.          EXERCISE LIMITATION

            Options designated as incentive stock options and granted after
December 31, 1986 shall be treated as options which are incentive stock options
under Section 422A of the Code only to the extent that the aggregate fair market
value of stock with respect to which such incentive stock options (determined
without regard to this Part) are exercisable for the first time by any
individual during any calendar year (under all incentive stock option plans of
the Company, its parent or subsidiaries, if any) does not exceed one hundred
thousand dollars ($100,000).

            (a)   Part 7 shall be applied by taking options into account in the
                  order in which they were granted.

            (b)   For purposes of Part 7, the fair market value of any stock
                  shall be determined as of the time the option with respect to
                  such stock is granted.

8.          PAYMENT

            The option price shall be payable upon the exercise of the option
either in United States dollars in cash or by check, or in common stock of the
Company.  If payment is made in common stock of the Company, the fair market
value of such stock must be

                                    - 6 -


equal to or greater than the option price and payment must be made in whole
shares of common stock.  The fair market value of such common stock on the date
of exercise of the option shall be determined by the Committee.

9.          TERMS OF OPTION

            The option shall be exercisable upon the terms and conditions and

                  optioned shares shall become exercisable each month
                  thereafter.

            (b)   Subject to the provisions of Section (d)(2) below, the option
                  as to the whole or any part thereof may be exercised only the
                  grantee thereof (hereinafter called the "Optionee").

                                    - 7 -


            (c)   Neither the whole nor any part of the option shall be
                  transferable by the Optionee or by the operation of law,
                  otherwise than by will of or by the laws of descent and
                  distribution applicable to a deceased Optionee, and then only
                  to the extent provided in Section (d)(2) below; and the
                  options and any and all rights granted to the Optionee
                  thereunder and not theretofore effectively and completely
                  exercised shall automatically terminate and expire upon any

                  transfer, or hypothecation of such rights, or upon the
                  bankruptcy or insolvency of the Optionee or of any person who
                  shall under said Section (d)(2) become entitled thereto under
                  the will of or the laws of descent and distribution applicable
                  to the Optionee.

            (d)   (1)   In case the Optionee's employment by the Company is
                        terminated for any reason other than death, the Optionee
                        may, but only within the thirty (30) days next
                        succeeding such termination, exercise any rights under
                        any option theretofore granted to the Optionee which the
                        Optionee would have been entitled to exercise on the
                        date of such termination;

                                    - 8 -


                  (2)   If the Optionee's employment by the Company terminates

                        Optionee would have been entitled to exercise on the
                        date of his death, but such exercise must be made within
                        the year next succeeding the death of the Optionee.

                  (3)   The Optionee's rights, including those of any person or
                        persons to whom an Option passes pursuant to the will of
                        the Optionee or the applicable laws of descent and
                        distribution, pursuant to the immediately preceding
                        subsections (1) and (2) are subject to all the terms and
                        conditions of the Plan, including without limitation,

                        set forth in Parts 13 and 14.

                  (4)   To the extent any option has not yet become exercisable
                        on the date Optionee's employment is terminated, such
                        option shall terminate.

                                    - 9 -


            (e)   With respect to any options granted under this Plan prior to
                  January 1, 1987, no such option may be exercised by an
                  employee while there is outstanding any incentive stock option
                  which was granted, before the granting of the option to be
                  exercised, to such employee under this or any other incentive
                  stock option plan of the Company (or its parent, predecessor,
                  or subsidiary corporations, if any).  This limitation shall
                  not apply to any options granted after December 31, 1986.

            (f)   In no event shall any option be exercised after the expiration
                  of ten (10) years from the date it is granted, but the
                  Committee may prescribe an earlier termination date in the
                  option.

            (g)   In the event an Optionee wishes to exercise an option
                  hereunder, the Optionee shall furnish a written notice of
                  intent to exercise to the Company at its general offices in
                  Lebanon, Missouri.  The Company shall thereupon furnish to the
                  Optionee a disclosure statement including such information, if
                  any, as may be deemed appropriate to comply with applicable
                  disclosure requirements and a questionnaire seeking such
                  information from the Optionee as may be necessary to confirm
                  the

                                    - 10 -


                  propriety of a sale of common stock to the Optionee without
                  registration.  If, following examination of the disclosure
                  statement and such further information as the Optionee wishes
                  to obtain from the Company, the Optionee wishes to exercise
                  the option, the Optionee shall provide to the Company a notice
                  of exercise specifying the number of such shares that the
                  Optionee wishes to purchase, together with a properly
                  completed questionnaire and a representation that the shares
                  are being acquired for investment and not with the view of a
                  resale of the same.  Upon receipt of a satisfactorily
                  completed questionnaire and notice of exercise, the Company
                  shall thereupon issue shares to Optionee in exchange for
                  payment of the option price.

10.         RECAPITALIZATION

            In the event of any stock dividend, subdivision, stock split,
combination of shares, reclassification, recapitalization, or if the Company
shall participate in a merger or consolidation  in which the Company is the
surviving corporation, or if other similar change in the capitalization of the
Company occurs affecting its common stock, the Committee shall make
correspondent adjustments in (1) the number of shares and the price per share
applicable to the outstanding options, (2) the

                                    - 11 -


number of shares then reserved for award under options thereafter to be granted,
and (3) applicable limitations set forth in this Plan with respect to the
granting of options.

11.         EFFECTIVE DATE OF PLAN

            This Plan shall become effective upon adoption by the Board of
Directors of the Company subject to ratification by the shareholders and subject
to compliance of all applicable law.  As to options granted under the 1983 Plan
and assumed by the Company by reason of the Corporate transactions referenced in
Section 1 hereof the Plan shall take effect as of October 28, 1988.

12.         TERM OF PLAN

            Options may be granted pursuant to the Plan from time to time within
a period of ten (10) years from the date the Plan is adopted, or the date the
Plan is approved by the shareholders, whichever is earlier.

13.         REPURCHASE OF STOCK

            All stock issued to any Optionee shall be subject to an agreement
permitting the Company to repurchase such stock upon the termination of
employment of the Optionee for any reason.  The purchase price upon such
repurchase shall be the fair market value of such stock on the date of
termination as determined by the Committee.  If the Optionee disagrees with the
Committee's determination of fair market value and if the Company does not

                                    - 12 -


withdraw its offer to repurchase, and if the Optionee so requests, the Committee
shall obtain, at the expense of the Company and the Optionee (such expense to be
shared equally by the Company and the Optionee), an appraisal by an independent
third party to determine the fair market value of such stock on the date of
termination and the Committee and the Optionee shall abide by the decision of
the third party.

14.         SALE OF STOCK

            All stock issued to any Optionee shall include a legend prohibiting
sale or transfer of the shares or any interest therein without compliance with
the Securities Act of 1933, as amended, and any applicable state laws or an
opinion of counsel, satisfactory to the Company, that such a registration is not
required.  All stock issued to any Optionee shall be subject to an agreement
that the Optionee shall not sell or transfer any stock or interest therein to a
third party without first offering to sell or transfer such stock to the Company
at a price equal to the price offered by such third party.  The Optionee's right
to sell stock that the Company does not purchase pursuant to the right of first
refusal set forth herein shall be limited to a sale to the third party offeree
on the terms and conditions offered by such offeree, such sales to be made
within 30 days of the Company's decision not to exercise its right of first
refusal.
