                  EXECUTIVE EMPLOYMENT AGREEMENT



          THE EXECUTIVE EMPLOYMENT AGREEMENT (the "Agreement") is
entered into as of the first day of January, 1 998, (the
"Effective Date"), by and between AMERICAN DISPOSAL SERVICES,
INC., a Delaware corporation (the "Company") and JOHN J.
McDONNELL, an individual (the "Officer").

                              RECITAL

          WHEREAS, the Officer has been employed by and currently
serves as the Company's Vice President-Engineering;

          WHEREAS, the Company recognizes Officer's substantial
contribution to the growth and success of the Company; and
desires to provide for continued employment of Officer in order
to reinforce and encourage his continued attention and dedication
to the Company as a member of the Company's senior management;

          WHEREAS, Company desires to continue to employ Officer
as Vice President-Engineering, and Officer is willing to continue
to accept such employment by Company, on the terms and subject to
the conditions set forth in the Agreement;

          NOW, THEREFORE, in consideration of the foregoing
mutual covenants contained herein and for other good and valuable
consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereto agree as follows:

1 .  Position and Duties; Location.

          During the Term (as defined in Paragraph 2 below) of
the Agreement, Officer agrees to be employed by and to serve the
Company as its Vice President Engineering subject to the control
of the Board of Directors (the "Board"), and the Company agrees
to employ and retain Officer in such capacities.  During the Term
(as defined in Paragraph 2 below) Officer agrees to devote
substantially all of his working time, energy, efforts and
abilities to the business affairs of the Company and its
subsidiaries.  Officer's principal place of business will be
located within 25 miles of Burr Ridge, Illinois.  The Company
shall provide Officer with working facilities and support
services as are suitable to his position and appropriate for the
performance of his duties.

2.   Term of Employment.

          The Term (the "Term") of the Agreement shall be for the
period commencing on the Effective Date and ending on the last
day of the eighteenth (1 8th) month following the Effective Date
(the "Termination Date"), unless terminated earlier pursuant to
the Agreement (the "Early Termination Date"); provided, however,
that commencing on the last day of the twelfth (12th) month
following the Effective Date and each subsequent anniversary
thereof, the Term shall be automatically extended for one (1)
additional year unless, no later than six (6) months before such
date, either party shall have given written notice to the other
that it does not wish to extend the Term of the Agreement.
References herein to the Term of the Agreement shall refer to
both the initial Term and any such extended Term.

3.   Compensation, Benefits and Reimbursement.

          3.1  Base Salary.  During the Term of the Agreement and
subject to the terms and conditions set forth herein, Company
agrees to pay to Officer an annual "Base Salary" equal to
          Thousand Dollars ($                     ), or such
higher amount as may from time-to-time be determined by the
Board.  Unless otherwise agreed in writing by Officer and
Company, the salary shall be payable in substantially equal
semimonthly installments in accordance with the standard policies
of Company in existence from time-to-time.

          3.2  Increases in Base Salary. Officer's Base Salary
shall be reviewed no less frequently than on each anniversary of
the Effective Date during the Term by the Board (or such
committee as may be appointed by the Board for such purpose).
The Base Salary payable to Officer may be increased on each such
anniversary date (and such other times as the Board or a
committee of the Board may deem appropriate during the Term of
the Agreement) to an amount determined by the Board (or a
committee of the Board).  Any increase in Base Salary or other
compensation shall in no way limit or reduce any other
obligations of Company hereunder and, once established at an
increased specified rate, Officer's Base Salary shall not be
reduced unless Officer otherwise agrees in writing.

          3.3  Bonus.  During the Term of the Agreement, Officer
shall be eligible for the following bonus:

               (a)  Target Bonus.  Officer shall be eligible to
receive an annual bonus for each fiscal year of the Company (or
portion thereof) during the Term of the Agreement as determined
below.  Any such bonus shall be payable within seventy-five (75)
days after the end of Company's fiscal year to which such bonus
relates; provided, however, that the Chief Executive Officer of
the Company may defer payment of such bonus for a period not to
exceed one year if such officer determines that deferral is in
the best interests of the Company.

               (b)  Determination of Bonus.  With respect to each
fiscal year during the Term, the actual amount of the bonus
payable pursuant to Subparagraph (a) shall be determined on the
basis of criteria with respect to the performance of Officer
and/or Company established by the Board (or a committee of the
Board) in consultation with the Chief Executive Officer of the
Company prior to the commencement of the fiscal year and such
other factors and conditions as the Board may deem relevant;
provided, however, that the criteria for the bonus for 1 998
shall be established in the first quarter of 1 998.

          3.4  Additional Benefits.  During the Term of the
Agreement, Officer shall be entitled to the following additional
benefits:

               (a)  Officer Benefits.  Officer shall be entitled
to such benefits as are generally provided by the Company to its
senior executive employees including, without limitation, (i)
Company stock incentive plans, annual incentive compensation
plans, profit sharing/pension plans, deferred compensation plans,
annual physical examinations, dental, vision, sick pay, and
medical plans, personal catastrophe and accidental death
insurance plans, financial planning and automobile arrangements,
retirement plans and supplementary executive retirement plans, if
any, and (ii) personal leave, sick leave and vacation leave to
the extent such leaves are provided to all senior executive
employees.  Officer is also entitled to the benefit of any life
and health insurance plans, pension, stock option plans and other
similar plans as the Company may have or may establish from time-
to-time for its senior executive employees.

               (b)  Vacation.  Officer shall be entitled to a
minimum of four (4) weeks of vacation during each year during the
Term of the Agreement and any extensions thereof, prorated for
partial years.  Any accrued vacation not taken during any year
may be carried forward to subsequent years; provided, that
Officer may not accrue more than eight (8) weeks of unused
vacation at any time.

               (c)  Life Insurance.  During Term of the
Agreement, Company shall, at its sole cost and expense, procure
and keep in effect term life insurance (a minimum two (2) year
term certain policy) on the life of Officer, payable to such
beneficiaries as Officer may from time-to-time designate, in the
aggregate amount of One Million Five Hundred Thousand Dollars
($1,500,000); provided, however, in no event shall the premiums
for such insurance policy exceed three times normal and customary
rates for a normal healthy male of similar age.  Such policy
shall be owned by Officer or by a member of his immediate family.
The Company shall have no incidents of ownership therein.

               (d)  Reimbursement for Expenses.  During the Term
of the Agreement, Company shall reimburse Officer for all
reasonable out-of-pocket business and/or entertainment expenses
incurred by Officer for the purpose of and in connection with the
performance of his services pursuant to the Agreement.  Officer
shall be entitled to such reimbursement upon the presentation by
Officer to the Company of vouchers or other statements itemizing
such expenses in reasonable detail consistent with Company's
policies.

               (e)  Automobile.  During the Term of the
Agreement, the Company will also make available to Officer an
automobile of a value and model consistent with past practices
and shall pay all operating expenses associated with such
automobile.

               (f)  Withholding.  Compensation and benefits paid
to Officer under the Agreement shall be subject to applicable
federal, state and local wage deductions and other deductions
required by law.

4.   Termination of the Agreement.

          4.1  Termination by Company Defined.

               (a)  Termination Without Cause.  Subject to the
provisions set forth in Paragraph 4.3 below, "Termination Without
Cause" shall constitute any termination by Company other than
termination for "Cause" (as defined in Paragraph 4.1 (b) below).

               (b)  Termination For Cause.  Subject to the
provisions set forth in Paragraph 4.3 below, prior to the
Termination Date, the Company shall have the right to terminate
the Agreement for "Cause"; provided, however, that Officer shall
not be deemed to have been terminated for Cause without (i)
reasonable written notice to Officer setting forth the reasons
for the Company's intention to terminate for "Cause", (ii) an
opportunity for the Officer, together with his counsel, to be
heard before the Board, and (iii) delivery to the Officer of a
written notice of termination (which date of delivery of such
notice shall be the Early Termination Date), as defined herein,
from the Board finding that in the good faith opinion of the
Board, Officer was guilty of conduct set forth therein, and
specifying the particulars thereof in detail.  For purposes of
the Agreement, "Cause" shall mean the following:

          A commission of a felony, a crime involving moral
          turpitude, embezzlement, misappropriation of property
          of the Company or a subsidiary, any other act involving
          dishonesty or fraud with respect to the Company or a
          subsidiary; a material breach of a directive of the
          Board which has not been cured within a specified
          reasonable time after written notice of breach; or a
          repeated failure after written notice to follow the
          reasonable directives of the Board.

               (c)  Termination by Reason of Death or Disability.
Subject to the provisions set forth in Paragraph 4.3 below, prior
to the Termination Date, Company shall have the right to
terminate the Agreement by reason of Officer's death or Permanent
Disability.  For purposes of the Agreement, "Permanent
Disability" shall mean the following:

          The Officer is unable to perform his duties hereunder
          for 1 80 days during any 365 consecutive days by reason
          of physical or mental disability.  The disability will
          be deemed to have occurred on the one hundred and
          eightieth (1 80th) day of Officer's absence or lack of
          adequate performance.

          4.2  Termination by Officer Defined.

               (a)  Termination Other Than For Good Reason.
Subject to the provisions set forth in Paragraph 4.3 below,
Officer shall have the right to terminate the Agreement for any
reason other than for Good Reason (as defined in Paragraph 4.2(b)
below), at any time prior to the Termination Date, upon written
notice delivered to Company thirty (30) days prior to the
effective date of termination specified in such notice (which
date shall be the applicable Early Termination Date).

               (b)  Termination For Good Reason.  Subject to the
provisions of Paragraph 4.3 below, Officer shall have the right
to terminate the Agreement prior to the Termination Date in the
event of the material breach of the Agreement by Company, if such
breach is not cured by Company within thirty (30) days after
written notice thereof specifying the nature of such breach has
been delivered to Company, or, following a Change in Control (as
defined in Paragraph 4.4(e) below), under the circumstances set
forth in Paragraph 4.2(c) below.  For purposes of the Agreement,
termination of the Agreement by Officer in the event of Company's
material breach of the Agreement in accordance with the
provisions of this Paragraph 4.2(b) shall be defined as
termination by Officer for "Good Reason."

               (c) Good Reason Following a Change in Control.
Following a Change in Control (as defined in Paragraph 4.4(e)
below), "Good Reason" shall mean, without Officer's express
written consent, a material breach of the Agreement by Company,
including the occurrence of any of the following circumstances,
which breach is not fully corrected within thirty (30) days after
written notice thereof specifying the nature of such breach has
been delivered to Company:

               (i)  the assignment to Officer of any duties
     inconsistent with the position in Company that Officer held
     immediately prior to the Change in Control, or an adverse
     alteration in the nature or status of Officer's
     responsibilities from those in effect immediately prior to
     such change;
               (ii) a substantial change in the nature of the
     business operations of Company;

               (iii)     a reduction by Company in Officer's
     annual base salary as in effect on the date hereof or as the
     same may be increased from time to time;

               (iv) the relocation of Company's principal execu-

     tive offices to a location more than 25 miles from Burr
     Ridge, Illinois (or, if different, the town in which such
     offices are located immediately prior to the Change in
     Control), or Company's requiring Officer to be based
     anywhere other than Company's principal executive offices
     except for required travel on Company's business to an
     extent substantially consistent with Officer's business
     travel obligations immediately prior to the Change in
     Control;

               (v)  the failure by Company to pay Officer any
     portion of his current compensation except pursuant to an
     across-the board compensation deferral similarly affecting
     all officers of Company and all officers of any person whose
     actions resulted in a Change in Control or any person
     affiliated with Company or such person, or to pay Officer
     any portion of an installment of deferred compensation under
     any deferred compensation program of Company, within seven
     (7) days of the date such compensation is due;

               (vi) the failure by Company to continue in effect
     any compensation plan in which Officer participates
     immediately prior to the Change in Control which is material
     to Officer's total compensation, unless an equitable
     arrangement (embodied in an ongoing substitute or
     alternative plan) has been made with respect to such plan,
     or the failure by Company to continue Officer's
     participation therein (or in such substitute or alternative
     plan) on a basis not materially less favorable, both in
     terms of the amount of benefits provided and the level of
     participation relative to other participants, as existed at
     the time of the Change in Control;

               (vii)  the failure by Company to continue to
     provide Officer with benefits substantially similar to those
     under any of Company's life insurance, medical, health and
     accident, or disability plans in which Officer was
     participating at the time of the Change in Control, the
     taking of any action by Company which would directly or
     indirectly materially reduce any of such benefits or deprive
     Officer of any material fringe benefit enjoyed by him at the
     time of the Change in Control, or the failure by Company to
     provide Officer with the number of paid vacation days to
     which he is entitled on the basis of years of service with
     Company in accordance with Company's normal vacation policy
     in effect at the time of the Change in Control or pursuant
     to Officer's existing employment agreement, if any; or

               (viii)  the failure of Company to obtain a
     satisfactory agreement from any successor to assume and
     agree to perform the Agreement.

          Notwithstanding the above, during the one year period
immediately following the occurrence of a Change in Control,
"Good Reason" shall mean termination of employment by the
Executive for any reason other than death or Permanent
Disability.

          Officer's right to terminate Officer's employment for
Good Reason shall not be affected by Officer's incapacity due to
physical or mental illness.  Officer's continued employment shall
not constitute consent to, or a waiver of rights with respect to,
any circumstance constituting Good Reason hereunder.

          4.3  -Effect of Termination.  In the event that the
Agreement is terminated by Company or Officer prior to the
Termination Date in accordance with the provisions of this
Paragraph 4, the obligations and covenants of the parties under
this Paragraph 4 shall be of no further force and effect, except
for the obligations of the parties set forth below in this
Paragraph 4.3, and such other provisions of the Agreement which
shall survive termination of the Agreement as provided in
Paragraph 6.1 1 below.  Except as otherwise specifically set
forth, all amounts due upon termination shall be payable on the
date such amounts would otherwise have been paid had the
Agreement continued through its Term; provided, however, that
Deferred Amounts (as defined in Paragraph 4.3(a)(i) below) shall
be payable within thirty (30) days following the Early
Termination Date.

          In the event of any such early termination in
accordance with the provisions of this Paragraph 4.3, Officer
shall be entitled to the following:

               (a)  Termination by Company.

                    (i)  Termination Without Cause.  In the event
     that Company terminates the Agreement without Cause pursuant
     to Paragraph 4.1 (a) above, Officer shall be entitled to (i)
     Earned Base Salary (as defined below); (ii) earned benefits
     and reimbursable expenses; (iii) any earned bonus which
     Officer has been awarded pursuant to the terms of the
     Agreement or any other plan or arrangement as of the Early
     Termination Date, but which has not been received by Officer
     as of such date; (iv) any compensation earned but deferred
     ("Deferred Amounts"); and (v) the Severance Payment (as
     defined in Paragraph 4.4 below).

                    (ii)  Termination For Cause.  In the event

     (iii) earned benefits and reimbursable expenses; and (iv)
     any Deferred Amounts.  Following delivery to Officer of the
     notice described in Paragraph 4.1 (b)(i), the Company may

     benefits as provided hereunder as if Officer continued to be
     employed until the delivery of the notice of termination

     any Deferred Amounts; and (v) all outstanding options
     (whether or not exercisable at the Early Termination Date)

               (b)  Termination by Officer.

                    (i)  Termination Other Than For Good Reason.

     Officer as of such date; (iv) any Deferred Amounts; and (v)
     the Severance Payment (as defined in Paragraph 4.4 below).

          The term "Earned Base Salary" shall mean all
semimonthly installments of the Base Salary which have become due
and payable to Officer, together with any partial monthly
installment prorated on a daily basis up to and including the
applicable Termination Date.

          4.4  Severance Payment.

               (a)  Definition of "Severance Payment." For
purposes of the Agreement, the term "Severance Payment" shall
mean an amount equal to the sum of (i) the Base Salary otherwise
payable to Officer during the remainder of the Term had such
early termination of the Agreement not occurred ("Severance
Period") and (ii) for each full or partial year remaining in the
Severance Period, the average of the annual bonuses earned by
Officer in the two (2) years immediately preceding the date of
termination (or if there are less than two (2) years immediately
preceding such date, an amount equal to the immediately preceding
bonus earned) ("Average Bonus"); provided, however, that in the
event that, following a Change in Control (as defined in
Paragraph 4.4(e) below), the Company terminates the Agreement
without Cause pursuant to Paragraph 4.1 (a) above or Officer
terminates the Agreement for Good Reason pursuant to Paragraph
4.2(c) above, the term "Severance Payment" shall mean an amount
equal to no less than three (3) times the sum of the Base Salary
then in effect and the Average Bonus which Average Bonus shall
not be less than 50% of Base Salary).

               (b)  Payment of Severance Payment.  In the event
that Officer is entitled to any Severance Payment pursuant to
Paragraph 4.3 above, that portion of such Severance Payment that
represents Base Salary shall be payable in monthly installments,
and that portion of such Severance Payment that represents the
Average Bonus shall be payable on the dates such amounts would
have been paid had Officer continued in Company's employment for
the Severance Period; provided, however, that in the event of a
Termination Following a Change in Control (as defined in
Paragraph 4.4(e) below), the Severance Payment shall be payable
in a lump sum within ten (1 0) days following such termination.

               (c)  Other Severance Benefits.  In the event that
Officer is entitled to any Severance Payment pursuant to
Paragraph 4.3 above, he shall also be entitled to:

          (i)  the full and immediate vesting of any awards
granted to Officer under the Company's stock option and incentive
compensation plans; and

          (ii)  to the extent elected by Officer within five days
of the Early Termination Date, in lieu of shares of Company
common stock issuable upon exercise of outstanding options (which
options shall be cancelled upon the making of the payment
referred to below), a lump sum payment, in cash, equal to the
product of (a) the excess of (x) in the case of ISOs granted
after the date hereof, the closing price of shares of Company
common stock as reported on the NASDAQ National Market on or
nearest the Early Termination Date (or, if not listed on such
exchange, on the nationally recognized exchange or quotation
system on which trading volume in shares of Company common stock
is highest), or in the case of all other options, the higher of
such closing price or the highest per share price for shares of
common stock of the Company actually paid in connection with any
Change in Control, over (y) the per share exercise price of such
option held by Officer (whether or not then fully exercisable),
and (b) the number of shares of common stock of the Company
covered by each such option as elected by Officer; provided,
however, that if the Company is prevented by the terms of its
debt instruments from making the payment described herein,
Officer shall immediately execute a cashless exercise of all
options for which such Officer elected to receive cash (whether
or not fully exercisable at the Early Termination Date) and shall
dispose of the common stock underlying such options as soon as
practicable and the Company will pay Officer the aggregate
difference between the price of the common stock at the time such
shares are sold and the price determined under (x) above;
provided further, that in the event and to the extent that such
shares cannot be sold for any reason, the Company will repurchase
such shares at the price determined under (x) above; provided,
however, that notwithstanding the foregoing, the following shall
apply with respect to a Termination without Cause pursuant to
Paragraph 4.3(a)(i) or a Termination For Good Reason prior to a
Change in Control pursuant to Paragraph 4.3(b)(ii); to the extent
Officer within five days of the Early Termination Date elects to
receive cash in lieu of shares of Company common stock issuable
upon exercise of outstanding options (which options shall be
cancelled upon the making of the exercises referred to below),
Officer shall immediately complete a cashless exercise of all
options for which Officer elects to receive cash (whether or not
fully exercisable at the Early Termination Date) and shall
attempt to dispose of the common stock underlying such options
within three weeks of such exercise and the Company will pay
Officer the aggregate difference between the price of the common
stock at the time such shares are sold and the price determined
under (x) above; provided further, that in the event and to the
extent such shares cannot be sold within the three week period
for any reason, the Company will repurchase such shares at the
price determined under (x) above; and

          (iii)  continued participation throughout the Severance
Period in all employee welfare and pension benefit plans,
programs or arrangements.  In the event Officer's participation
in any such plan, program or arrangement is barred, Company shall
arrange to provide Officer with substantially similar benefits.

               (d)  Full Settlement of All Obligations.  Officer
hereby acknowledges and agrees that any Severance Payment paid to
Officer hereunder shall be deemed to be in full and complete
settlement of all obligations of Company under the Agreement.

combination with the ownership of any trustee or other fiduciary

no event shall the Officer be obligated to seek other employment
or take any other action by way of mitigation of the amounts
payable to Officer under any of the provisions of this Agreement

performance thereof (including as a result of any contest
initiated by Officer about the amount of any payment due pursuant
to this Agreement); provided, however, that in the event that it
is finally determined by arbitration pursuant to Paragraph 5.8
that Officer was terminated for Cause or that, in the case of
termination of this Agreement by Officer, Good Reason did not
exist, then Officer shall be obligated to repay to Company the
full amount of all such legal fees and expenses paid for Officer
by Company in connection with that contest.

          5.2  Confidentiality.  Officer agrees that all
confidential and proprietary information relating to the business

public domain or comes within the public domain without any
breach of the Agreement.

          5.3  Waiver.  The waiver of the breach of any provision

the Agreement to the maximum extent permitted under applicable
law of the State of Illinois or any successor provision thereof
and any other applicable state law, and shall pay Officer's

IN WITNESS WHEREOF, the parties hereto have executed the
Agreement.

                         Company:

                         AMERICAN DISPOSAL SERVICES, INC.,
                         a Delaware corporation


                         By:

                                 Name
                                 Title

                         Date:



                         OFFICER:



                         Name

                         Date:

























                                                       ANNEX A


     The Gross-Up Payment shall be equal to the excess of the
     Total Payments over the payment provided for by this
     paragraph.  For purposes of determining whether any of the
     Total Payments will be subject to the Excise Tax and the
     amount of such Excise Tax, (i) all payments or benefits
     received or to be received by Officer in connection with a
     Change in Control or the termination of Officer's employment
     (whether payable pursuant to the terms of the Agreement or
     of any other plan, arrangement or agreement with
     Corporation, its successors, any person whose actions result
     in a Change in Control or any person affiliated (or which,
     as a result of the completion of the transactions causing a
     Change in Control, will become affiliated) with Corporation
     or such person within the meaning of Section 1 504 of the
     Code (the "Total Payments")) shall be treated as "parachute
     payments" (within the meaning of Section 280G(b)(2) of the
     Code) unless, in the opinion of tax counsel selected by
     Corporation's independent auditors and reasonably acceptable
     to Officer, such payments or benefits (in whole or in part)
     do not constitute parachute payments, including by reason of
     Section 280 G(b)(4)(A) of the Code, and all "excess
     parachute payments" (within the meaning of Section
     280G(b)(1) of the Code) shall be treated as subject to the
     Excise Tax, unless in the opinion of such tax counsel such
     excess parachute payments represent reasonable compensation
     for services actually rendered within the meaning of Section
     280G(b)(4)(B) of the Code, or are not otherwise subject to
     the Excise Tax, and (ii) the value of any noncash benefits
     or any deferred payment or benefit shall be determined by
     the Corporation's independent auditors in accordance with
     the principles of Sections 280G(d)(3) and (4) of the Code.
     For purposes of determining the amount of the Gross-Up
     Payment, Officer shall be deemed to pay federal income taxes
     at the highest marginal rate of federal income taxation in
     the calendar year in which the Gross-Up Payment is to be
     made and state and local income taxes at the highest
     marginal rate of taxation in the state and locality of the
     residence of Officer on the Early Termination Date, net of
     the maximum reduction in federal income taxes that could be
     obtained from deduction of such state and local taxes.
