                              EMPLOYMENT AGREEMENT


         THIS EMPLOYMENT AGREEMENT (this "Agreement") is entered into as of
April 3, 1995, by and between USA WASTE SERVICES, INC., an Oklahoma corporation
(the "Company"), and GREGORY T. SANGALIS ("Employee").

                                R E C I T A L S:

         The Company recognizes that the efforts of its officers and key
management employees have contributed and will continue to contribute to the
growth and success of the Company.

         The Company believes that, in the Company's best interest, it is
essential that its officers and key management employees, including the
Employee, be retained and that the Company be in a position to rely on their
ongoing dedication and commitment to render services to the Company.

         The Company wishes to take steps to assure that the Company will
continue to have the Employee's services available to the Company by entering
into an agreement with the Employee concerning his employment by the Company.

         In consideration of the foregoing, the mutual provisions contained
herein, and for other good and valuable consideration, the parties agree with
each other as follows:

1.       EMPLOYMENT

         A.      The Company hereby employs the Employee and the Employee
hereby accepts employment as the Vice President, General Counsel, and Corporate
Secretary of the Company on the terms and conditions hereinafter set forth.
The Employee shall perform such duties, and have such powers, authority,
functions and responsibilities for the Company and corporations affiliated with
the company (commensurate with such employment capacity), and have such
additional duties, powers, authority, functions and responsibilities as may be
assigned to him by the Company's Board of Directors (or a committee thereof) or
by the Chief Executive Officer which are not (except with the Employee's
consent) inconsistent with or which interfere with or detract from those vested
in or being performed by the Employee for the Company.

         B.      The Employee shall not, during the term of his employment
under this Agreement, be engaged in any other activities if such activities
interfere materially with the Employee's current duties, authority and
responsibilities for the Company, except for those other activities as shall
hereafter be carried on with the Company's consent.  The Employee shall be
entitled to carry on those activities as have heretofore been carried on with
the Company's consent including, without limitation, making and managing his
personal investments provided such investments or other activities do not
violate in any material respect the terms of Sections 6, 7 or 8 hereof.

2.       TERM

         A.      Subject only to the provision of either Section 3(D) or
Section 4 hereof, the term of the Employee's employment under this Agreement
shall be for a continually renewing term of three (3) years without any further
action by either the Company or the Employee, it being the intention of the
parties that there shall be continuously a term of three (3) years duration of
the Employee's Employment under this Agreement until an event has occurred as
described in, or one of the parties shall have made an election pursuant to,
the provisions of either Section 3(D) or Section 4 of this Agreement; provided,
however, that if no such event has occurred or election has been made, such
term shall terminate on the date the Employee becomes age 65.

3.       COMPENSATION

         For all services rendered by the Employee while on active status under
this Agreement, the Company agrees to compensate the Employee for each
compensation year (January 1 through December 31) during the term hereof, as
follows:

         A.      Base Salary.  A base salary shall be payable to the Employee
by the Company as a guaranteed annual amount under this Agreement equal
initially to $175,000, for each compensation year (as the same may be adjusted
as provided herein, the "Base Salary"), which shall be payable in the intervals
consistent with the Company's normal payroll schedules (but in no event less
than semi-monthly).  The Base Salary shall be subject to being increased (but
not decreased or adjusted other than as provided in Section 4 of this
Agreement) in the sole discretion of the Compensation Committee of the Board of
Directors of the Company (or a similar Board committee composed solely of
"outside" directors, hereinafter referred to as the "Compensation Committee")
but only in such form and to such extent as the Compensation Committee may from
time to time approve.  The official action of the Compensation Committee
increasing the Base Salary payable to the Employee shall modify the amount of
Base Salary stated in this Section 3(A).

         B.      Other Compensation.  The Employee shall be entitled to
participate in any incentive or supplemental compensation plan or arrangement
instituted by the Company and covering its principal executive officers and to
receive additional compensation from the Company in such form and to such
extent, if any, as the Compensation Committee may in its sole discretion from
time to time specify and determine with respect to the Company's principal
executive officers generally; provided, however, in the event the Employee
shall go on part-time status for any reason, the Employee shall nevertheless be
entitled to be paid pro rata incentive or supplemental compensation for the
fiscal year ending in the compensation year in which the Employee goes on
part-time status, for the number of calendar months during such fiscal year
that Employee shall have been on active status, at the same time, on the same
basis and to the same extent as any of the Company's principal executive
officers on active status are selected by the Compensation Committee to receive
any incentive or supplemental compensation award for such fiscal year.  The
phrase "principal executive officer" as used in this Agreement shall mean




                                      -2-
<PAGE>   3
the chief executive officer of the Company and other senior corporate officers
of the Company who are from time to time designated as principal executive
officers by the Compensation Committee. The Employee shall be entitled to
participate in the Company's bonus compensation plan and shall be entitled to a
bonus of up to 50% of his base salary upon achievement of predetermined goals
and objectives mutually agreed upon by the Employee and the Company at the
beginning of each year; provided, however, that the Compensation Committee of
the Board of Directors reserves the right in its discretion to change the terms
and conditions for payment of bonuses by the Company or to suspend, terminate,
or limit the Company's bonus plan and may from time-to-time establish such
terms and conditions for participation in the bonus plan as it shall deem
appropriate and in the best interests of the Company. The Employee shall be
paid the sum of $50,000 on commencement of his employment under this Agreement,
which shall be offset against the amount of any bonus awarded to the Employee
under the Company's bonus compensation plan with respect to fiscal 1995
(notwithstanding that such bonus may not be declared or awarded by the Company
until 1996).

         C.      Tax Indemnity.  Should any of the payments of Base Salary,
other incentive or supplemental compensation, benefits, allowances, awards,
payments, reimbursements or other perquisites (including the payments provided
for under this Section 3(C), singly, in any combination or in the aggregate,
that are provided for hereunder to be paid to or for the benefit of the
Employee (including, without limitation, the payment provided for in Section
3(D) hereof) or under any other plan, agreement or arrangement between the
Employee and the Company, be determined or alleged to be subject to an excise
or similar purpose tax pursuant to Section 4999 of the Internal Revenue Code of
1986, as amended (the "Code"), or any successor or other comparable federal,
state or local tax laws, the Company shall pay to the Employee such additional
compensation as is necessary (after taking into account all federal, state and
local income taxes payable by the Employee as a result of the receipt of such
additional compensation) to place the Employee in the same after tax position
(including federal, state and local taxes) he would have been in had no such
excise or similar purpose tax (or any interest or penalties thereon) been paid
or incurred.  The Company hereby agrees to pay such additional compensation
within five (5) business days after the Employee notifies the Company that the
Employee intends to file a tax return which takes the position that such excise
or similar purpose tax is due and payable in reliance on a written opinion of
the Employee's tax counsel (such tax counsel to be chosen solely by the
Employee) that it is more likely than not that such excise tax is due and
payable.  The costs of obtaining such tax counsel's opinion shall be borne by
the Company, and as long as such tax counsel was chosen by the Employee in good
faith, the conclusions reached in such opinion shall not be challenged or
disputed by the Company.  If the Employee intends to make any payment with
respect to any such excise or similar purpose tax as a result of an adjustment
to the Employee's tax liability by any federal, state or local tax authority,
the Company will pay such additional compensation by delivering its cashier's
check payable in such amount to the Employee within five (5) business days
after the Employee notifies the Company of his intention to make such payment.
Without limiting the obligation of the Company hereunder, the Employee agrees,
in the event the Employee makes any payment pursuant to the preceding sentence,
to negotiate with the Company in good faith with respect to procedures





                                      -3-

reasonably requested by the Company which would afford the Company the ability
to contest the imposition of such excise tax; provided, however, that the
Employee will not be required to afford the Company any right to contest the
applicability of any such excise tax to the extent that the Employee reasonably
determines (based upon the opinion of his tax counsel) that such contest is
inconsistent with the overall tax interests of the Employee.

D.       (i)     Change of Control - Operation of Section 3(D).

                          (a)     This Section 3(D) shall be effective, but not
                 operative, immediately upon execution of this Agreement by the
                 parties hereto and shall remain in effect so long as the
                 Employee remains employed by the Company on active status and
                 for twelve (12) months after the Employee goes on part-time
                 status, but shall not be operative unless and until there has
                 been a Change in Control, as defined in subsection (i)(b)
                 hereof.  Upon such a Change in Control, this Section 3(D)
                 shall become operative immediately.

                          (b)     "Change in Control" shall mean a change in
                 control of the Company that shall be deemed to have occurred
                 if and when, with or without the approval of the Board of
                 Directors of the Company incumbent prior to the occurrence,

                                  (1)      more than 25% of the Company's
                          outstanding securities entitled to vote in elections
                          of directors shall be acquired by any person (as such
                          term is used in Sections 13(d) and 14(d) of the
                          Securities Exchange Act of 1934, as amended) other
                          than by any person which includes the Employee; or

                                  (2)      as the result of a tender offer,
                          merger, consolidation, sale of assets or contested
                          election, or any combination of such transactions,
                          the persons who were directors immediately before the
                          transaction shall cease to constitute a majority of
                          the Board of Directors of the Company or of any
                          successor to the Company;

                 provided, however, that neither (A) the acquisition by John G.
                 Rangos, Sr. and the Rangos family of more than 25% of the
                 Company's outstanding securities entitled to vote in the
                 election of directors in connection with the business
                 combination of the Company and Chambers Development Company,
                 Inc., nor (B) a business combination involving the Company and
                 another solid waste management company, which is approved by a
                 75% majority of the Board of Directors of the Company
                 incumbent prior to the occurrence of such business
                 combination, notwithstanding that a principal shareholder or
                 shareholders of such other solid waste management company
                 acquires more than 25% of the Company's outstanding securities
                 entitled to vote in the election of directors in connection
                 with such business combination, shall be deemed to be a
                 "Change in Control."

                 (ii)     Employee's Rights Upon Change of Control.  If, while
         the Employee is employed on active status by the Company, or if within
         twelve (12) months after the Employee has been placed on part-time
         status pursuant to either Section 4(C)(i), (ii) or (iii) or Section
         4(G), a Change in Control (as defined in subsection (b) of Section
         3(D)(i)) occurs and one or more of the following events occurs:

                          (a)     The assignment to the Employee of duties,
                 responsibilities, or status inconsistent with his duties,
                 responsibilities, and status prior to the Change in Control or
                 a reduction or alteration in the nature or status of the
                 Employee's duties and responsibilities from those in effect
                 prior to the Change in Control;

                          (b)     A reduction by the Company in the Employee's
                 Base Salary (as in effect prior to the Change in Control);

                          (c)     The failure by the Company to continue in
                 effect the Company's insurance, disability, stock option plan,
                 or any other employee benefit plans, policies, practices, or
                 arrangements in which the Employee participates, or the
                 failure of the Company to continue the Employee's
                 participation therein on substantially the same basis, both in
                 terms of the amount of benefits provided and the level of the
                 Employee's participation relative to other participants, as
                 existed prior to the Change in Control;

                          (d)     The failure of the Company to obtain a
                 satisfactory agreement from the successor to the Company to
                 assume and agree to perform this Agreement;

                          (e)     Any purported termination by the Company of
                 the Employee's employment other than pursuant to Section
                 4(A)(i) or 4(A)(ii); or

                          (f)     the person who was Chief Executive Officer of
                 the Company immediately before the transaction shall ceases to
                 be the Chief Executive Offcier of the Company or the the
                 persons who were directors immediately before the transaction
                 shall cease to constitute a majority of the Board of Directors
                 of the Company,

the Employee may, in his sole discretion, within three (3) months after the
date of the Change of Control, give notice to the Chief Executive Officer of
the Company that he intends to elect to exercise his rights under this Section
3(D) (the "Notice of Intention").  The right to give such Notice of Intention
to elect to receive the payment provided for in subsection (iii) of this
Section 3(D) shall continue for three (3) months from the date of the Change of
Control irrespective of any action by the Company pursuant to Section 4(A)(iii)
or Section 4(G) within such three (3) month period.  Within thirty (30) days
after the Company's receipt of the Notice of Intention, the Company shall
provide written notice to the Employee setting forth the Company's computation
of the amount that would be payable pursuant to subsection (iii) of this
Section 3(D),





                                      -5-
<PAGE>   6
accompanied by the written opinion of the Company's independent certified
public accountants confirming the Company's computation.  If the Employee takes
exception to the Company's computation of such amount, the Employee may (but
shall not be prejudiced in his right to later contest the amount actually paid
by failure to do so) give a further written notice to the Company setting forth
in reasonable detail the Employee's exceptions to the Company's computation,
accompanied by the written opinion of the Employee's tax advisor confirming the
basis for such exceptions.  Exercise by the Employee of his rights pursuant to
this Section 3(D) shall only be made by giving further notice to the Chief
Executive Officer of the Company (the "Notice of Exercise") within six (6)
months from the date of the Notice of Intention.

                 (iii)    Payment upon Change of Control.

                          (a)     If the Employee gives the Notice of Exercise
                 described in subsection (ii) of this Section 3(D) to the
                 Company, the Company shall pay the Employee a lump sum amount
                 equal to three (3) times the Employee's base amount (as
                 defined by Section 280(G) of the Code), less one dollar
                 ($1.00).  The Company shall, within five (5) business days
                 after the date of the Notice of Exercise, deliver to the
                 Employee its cashier's check in the amount payable pursuant to
                 this subsection (iii)(a) of Section 3(D), and payment of such
                 amount shall terminate the Employee's rights to receive any
                 and all other payments, rights or benefits pursuant to
                 Sections 3(A), 3(B), 4 and 5 of this Agreement, other than any
                 payments, rights or benefits arising (x) pursuant to Section
                 3(C), subsection (iii) of Section 3(D), Section 3(E) or
                 Section 12 of this Agreement, or (y) from any other agreement,
                 plan or policy which by its terms or by operation of law
                 provides for the continuation of such payments, rights or
                 benefits after the termination of the Employee's relationship
                 with the Company.

                          (b)     Such lump sum payment shall be in addition to
                 and shall not be offset or reduced by (x) any other amounts
                 that have accrued or have otherwise become payable to the
                 Employee or his beneficiaries, but have not been paid by the
                 Company at the time the Employee gives Notice of Exercise
                 pursuant to this Section 3(D) including, but not limited to,
                 salary, severance pay, consulting fees, disability benefits,
                 termination benefits, retirement benefits, life and health
                 insurance benefits, or any other compensation or benefit
                 payment that is part of any valid previous, current, or future
                 contract, plan or agreement, written or oral, or (y) any
                 indemnification payments that may be or become payable to the
                 Employee pursuant to the provisions of the Company's
                 Certificate of Incorporation, By-laws, or similar policy,
                 plan, or agreement relating to the indemnification of
                 directors or officers of the Company under certain
                 circumstances.

                 E.       Employee's Expenses.  All costs and expenses
         (including reasonable legal, accounting and other advisory fees)
         incurred by the Employee to (w) defend the validity





                                      -6-
<PAGE>   7
         of this Agreement (x) contest any determinations by the Company
         concerning the amounts payable (or reimbursable) by the Company to the
         Employee under this Agreement, (y) determine in any tax year of the
         Employee the tax consequences to the Employee of any amounts payable
         (or reimbursable) under Section 3(C) or (D) hereof, or (z) prepare
         responses to an Internal Revenue Service audit of, and to otherwise
         defend, his personal income tax return for any year which is the
         subject of any such audit, or an adverse determination, administrative
         proceedings or civil litigation arising therefrom that is occasioned
         by or related to an audit by the Internal Revenue Service of the
         Company's income tax returns, are, upon written demand by the
         Employee, to be promptly advanced or reimbursed to the Employee or
         paid directly, on a current basis, by the Company or its successors.

4.       TERMINATION, PART-TIME STATUS, AND REVISED COMPENSATION, DEATH,
         DISABILITY

         A.      Termination.  The employment of the Employee under this
Agreement, while the Employee is on active status, may be terminated at any
time by the Company, acting through its Board of Directors (and not a committee
thereof),

                 (i)      only for cause in the event of (x) the Employee's
         final conviction of a felony crime involving moral turpitude, or (y)
         the Employee's deliberate and intentional continuing refusal to
         substantially perform his duties and obligations under this Agreement
         (except by reason of incapacity due to illness or accident) if he
         shall have either failed to remedy such alleged breach within
         forty-five (45) days from his receipt of written notice from the Chief
         Executive Officer the Company demanding that he remedy such alleged
         breach, or shall have failed to take reasonable steps in good faith to
         that end during such forty-five (45) day period and thereafter,
         provided that there shall have been delivered to the Employee a
         further notice after the end of such forty-five (45) day period
         asserting that the Board of Directors has determined that the Employee
         was guilty of conduct set forth in this clause (y), that the Employee
         has failed to take reasonable steps in good faith to remedy such
         alleged breach, and specifying the particulars thereof in detail, and
         provided further that the Employee thereafter shall have received a
         certified copy of a resolution of the Board of Directors of the
         Company adopted by the affirmative vote of not less than three-fourths
         of the entire membership of the Board of Directors at a meeting called
         and held for that purpose and at which the Employee was given an
         opportunity to be heard, finding that the Employee was guilty of
         conduct set forth in this clause (y), that the Employee has failed to
         take reasonable steps in good faith to remedy such alleged breach, and
         specifying the particulars thereof in detail,

                 (ii)     upon a determination that the Employee has engaged in
         willful fraud or defalcation involving material funds or other assets
         of the Company, or





                                      -7-
<PAGE>   8
                 (iii)    for any reason in its sole discretion upon written
         notice to the Employee effective (subject to the provisions of Section
         4(D) (iii) hereof) on the date that is three (3) years after the date
         on which such notice is received by the Employee.

         B.      Termination Payment For Cause.  In the event of termination of
the Employee's employment under this Agreement by the Company under either
Section 4(A)(i) or (ii), the Employee shall only be entitled to receive the
monthly installment of his Base Salary being paid at the time of such
termination, and, if applicable, other compensation, due hereunder, computed on
a pro rata basis, up to the effective date of such termination.

         C.      (i)      Part-time Status-Election by Company.  In the event
         the Company shall give Employee notice of termination of the
         Employee's employment under this Agreement pursuant to Section
         4(A)(iii), the Employee shall, subject to the provisions of Section
         4(D)(iii) and (vii), be placed on part-time employment status for a
         period of three (3) years after the date on which such notice is
         received by the Employee.

                 (ii)     Termination - Election by Employee.  Employee shall
         have the right at any time during his employment on active status, by
         giving written notice to the Chief Executive Officer of the Company,
         to terminate the Employee's employment under this Agreement effective
         ninety (90) days after the date on which such notice is given by the
         Employee.  In the event the Employee shall make such election under
         this Section 4(C)(ii), the Employee shall, in addition to all other
         reimbursements, payments or other allowances required to be paid under
         this Agreement or under any other plan, agreement or policy which
         survives the termination of this Agreement, be entitled to be paid, in
         addition to the Base Salary payable during such ninety (90) day period
         after the giving of such notice, a lump sum payment payable by
         delivery of the Company's cashier's check within five (5) business
         days after the end of such ninety (90) day period, in an amount equal
         to three (3) monthly installments of the Base Salary (less required
         tax withholding) in effect pursuant to Section 3(A) hereof at the time
         the Employee makes such election under this Section 4(C)(ii).
         Thereupon, this Agreement shall terminate and Employee shall have no
         further rights under or be entitled to any other benefits of this
         Agreement, provided that the provisions of Sections 3(C) and (E), 6,
         7, 8 and 12 shall survive such termination.

         D.      Employee's Rights on Part-time Status.  During the period that
the Employee is on part-time status,

                 (i)      The Company shall pay Employee a revised, guaranteed
         minimum annual Base Salary from the date the Employee goes on
         part-time status for a period of three (3) years in an amount equal to
         seventy-five percent (75%) of the average of the total annual direct
         compensation paid to the Employee by the Company (whether under this
         Agreement, a predecessor agreement or otherwise) for the two (2)
         highest of the three (3) compensation years immediately preceding the
         compensation year in which the notice





                                      -8-
<PAGE>   9
         specified in Section 4(A)(iii), or Section 4(G) of this Agreement is
         given.  As used in this Agreement, the phrase "total annual direct
         compensation" shall mean the sum of the gross amount of Base Salary
         (as from time to time adjusted) paid to the Employee during a
         compensation year and all other forms of direct compensation for a
         compensation year (including, but not limited to, incentive or
         supplemental compensation awards made to the Employee for the fiscal
         year ending in each of such compensation year), whether or not paid to
         the Employee during a compensation year, (x) including any amounts
         paid by the Employee into any savings, deferred compensation or
         similar Company sponsored plan or arrangement, and (y) excluding any
         amounts that must be recognized as compensation in any such
         compensation year as a result of the Employee's exercise of a stock
         option or receipt of an award or unit of the Company's (or any
         successor's) stock;

                 (ii)     The revised, guaranteed minimum annual Base Salary
         payable by the Company to the Employee pursuant to this Section 4(D)
         shall be increased (but not decreased) annually on the first
         anniversary of the date of the Employee's going on part-time status
         and each anniversary thereafter, on a compound basis, by the same
         percentage increase (if any) in the Consumer Price Index for All Urban
         Consumer's - All Items Index, for Dallas, Texas (or any substantially
         similar index published for the same area) as published by the U.S.
         Department of Labor, Bureau of Labor Statistics for the twelve (12)
         month period immediately preceding the first anniversary of the date
         of the Employee's going on part-time status and on each yearly
         anniversary thereafter;

                 (iii)    (1)     The Employee shall continue to participate
                 (at not less than his highest levels of participation or
                 coverage during the last twelve (12) months the Employee was
                 on active status) in all of the Company's pension, group life,
                 medical, dental, accidental death or disability insurance,
                 thrift, savings, deferred compensation, stock option, unit or
                 award plans, vacation plans, automobile allowances and all
                 other Company benefit plans, fringe benefits, allowances and
                 accommodations of employment on active status that are
                 afforded to the principal executive officers of the Company,

                          (2)     With respect to any stock option, unit or
                 award plan of the Company as referred to in this Section
                 4(D)(iii), the Employee's right to continue participation at
                 and consistent with his highest levels of participation during
                 the last twelve (12) months the Employee was on active status,
                 (x) is intended to include (but only to the extent consistent
                 with the Company's treatment of its principal executive
                 officers) the Employee receiving renewal and/or replacement
                 grants of or awards for options or units on or with respect to
                 the Company's common stock (for not less than the same number
                 of shares or units, at the fair market value prevailing at the
                 time, and otherwise on terms and conditions no more or less
                 favorable than such grants or awards are made to the Company's
                 principal executive officers who are then on active employment
                 status) consistent with the Company's stock option plan as
                 then existing, not more than thirty (30)

                 days after the date any of the previous options or units are
                 cancelled, vest or expire (or would have expired but for their
                 exercise by the Employee), and (y) solely for the purposes of
                 any stock options, units or awards outstanding at the time the
                 Employee goes on part-time status or for any renewal or
                 replacement grants or awards, the Employee's status as an
                 "employee" or, thereafter, the Employee's status as an
                 "affiliate" of the Company (or of any successor thereto) shall
                 continue to the last date of expiration, cancellation, vesting
                 or exercise, as the case may be, of any and all of such
                 outstanding stock options, units or awards or renewal or
                 replacement grants or awards, and

                          (3)     If the Company is merged into or consolidated
                 with another corporation under circumstances where the Company
                 is not the surviving corporation, or if the Company's voting
                 common stock is no longer publicly traded on a national
                 securities exchange, or if the Company sells or disposes of
                 substantially all its assets to another corporation, then any
                 such renewal and/or replacement grants of or awards for
                 options or units pursuant to subparagraph (x) of Section
                 4(D)(iii)(2) shall be made in or for the shares of such stock
                 or other securities as the holders of shares of the Company's
                 voting common stock received pursuant to the terms of the
                 merger, consolidation or sale, and

                          (4)     If any of the Company's pension; group life,
                 medical, dental, accidental death, or disability insurance;
                 deferred compensation; thrift, savings, stock option, unit or
                 award plans; or any other Company benefit plans, fringe
                 benefits, allowances or accommodations of employment that were
                 available to the Employee at any time during the last twelve
                 (12) months the Employee was on active status shall not
                 continue to be maintained by the Company (or by any successor
                 thereto) or are otherwise not made available to the Employee,
                 the Company (or any successor thereto) shall provide for or
                 make available to the Employee substantially similar economic
                 benefits (and tax benefits attendant thereto) through such
                 alternative means and upon such terms as shall be reasonably
                 satisfactory to the Employee, provided that nothing in this
                 clause (4) shall obligate the Company to provide for or make
                 any such substantially similar alternative benefits available
                 to the Employee if the Company (or any successor thereto) does
                 not have such benefits available either directly or indirectly
                 (whether or not granted) for its principal executive officers.

                 (iv)     The Employee shall otherwise be entitled to all other
         principal executive officer perquisites, allowances and benefits on
         the same terms and conditions as such are from time to time made
         available generally to the other principal executive officers of the
         Company (or any successor thereto) but in no event less than the
         highest level of the perquisites, allowances and benefits that were
         available to the Employee during the last twelve (12) months of his
         employment on active status;





                                      -10-
<PAGE>   11
                 (v)      The Employee shall otherwise continue to receive all
         the rights and benefits of this Agreement including, without
         limitation, those rights and benefits (not inconsistent with this
         Section 4(D)) that are set forth in Sections 3(C), 3(E), 5, 9 and 12
         hereof;

                 (vi)     The Employee shall not be prevented from accepting
         other employment while on part-time status or engaging in (and
         devoting substantially all of his time to) other business activities
         that are not in conflict in any material respect with the limitations
         set forth in Section 6 hereof;

                 (vii)    This Agreement and Employee's continuing employment
         on part-time status may be terminated at any time by the Company (x)
         pursuant to the provisions of Section 4(A)(ii), or (y) acting through
         its Board of Directors (and not a committee thereof) only if the
         Employee knowingly violates in any material respect the provisions of
         Sections 6, 7 and 8, respectively, as found by final judgment of a
         court of competent jurisdiction;

                 (viii)   While on part-time status and except as otherwise
         required herein, the Employee shall not be required to perform any
         regular duties for the Company (except to provide such services
         consistent with the Employee's educational background, experience and
         prior positions with the Company, as may be acceptable to the
         Employee) or to seek or accept additional employment with any other
         person or firm (although the Employee shall be free to do so so long
         as accepting such additional employment or engaging in other business
         activity is not in conflict in any material respect with the
         limitations set forth in Section 6 of this Agreement).  If the
         Employee, at his discretion, shall accept any such additional
         employment or engage in any such other business activity consistent in
         all material respects with Section 6 of this Agreement, there shall be
         no offset, reduction or effect upon any rights, benefits or payments
         to which the Employee is entitled pursuant to this Agreement.
         Furthermore, the Employee shall have no obligation to account for,
         remit, rebate or pay over to the Company any compensation or other
         amounts earned or derived in connection with such additional
         employment or business activity consistent in all material respects
         with Section 6 of this Agreement; and

                 (ix)     The Employee shall, however, make himself generally
         available for special projects or to consult with the Company and its
         employees at such times and at such places as may be reasonably
         requested by the Company and which shall be reasonably satisfactory to
         the Employee and consistent with the Employee's regular duties and
         responsibilities in the course of his then new occupation or other
         employment, if any.

         E.      After the termination of the Employee's employment on
part-time status, the former Employee shall remain an "affiliate" of the
Company for the period described in Section 4(D)(iii)(2) hereof and during such
time shall continue to be available to consult with the Company and its
employees at such time and at such places as may be reasonably convenient and
acceptable to the former Employee and in such manner as may be consistent with
the former Employee's educational background, experience and prior positions
with the Company and with





                                      -11-
<PAGE>   12
his regular duties and responsibilities in the course of his then new
occupation or other employment, if any.

         F.      Death.  In the event of the Employee's death during the term
of his employment hereunder, the Company shall pay to the Employee's surviving
spouse or to the executor or administrator of the Employee's estate (if his
spouse shall not survive him) an amount equal to the installments of his Base
Salary then payable pursuant to Sections 3(A) or 4(D), as the case may be, for
the month in which he dies, and for the greater of (i) the balance of the term
remaining under this Agreement, or (ii) two (2) years.

         G.      Disability.  The Employee shall be covered by the Company's
disability benefit plan as such plan may from time to time exist.  The Company
may eliminate or change the terms and conditions of said plan at its discretion
with no liability to the Employee other than the liability, if any, under such
plan which may have accrued up to the elimination or change of such plan.  In
the event because of physical or mental illness or personal injury while the
Employee is on active status or part-time status, the Employee shall become
permanently unable or disabled such that he is unable to perform, and in all
reasonable medical likelihood, going to continue indefinitely to be unable to
perform his normal duties in his regular manner, as determined by independent,
competent medical authority.

                 (i)      if such disability determination occurs while the
         Employee is on active status, the Company may elect (but shall not be
         obligated) to terminate the Employee's employment under this Agreement
         on a date which is not less than three (3) years after the date on
         which written notice of such termination is received by the Employee
         in which event the Employee shall be placed on part-time status, and
         the Company shall pay to the Employee the Base Salary payable pursuant
         to Section 4(D)(i) for a period not less than three (3) years
         thereafter; or

                 (ii)     if such disability determination occurs while the
         Employee is on part-time status pursuant to Section 4(C)(i) or (ii),
         the Company shall continue to pay to the Employee the amount of his
         Base Salary then payable for the greater of (x) the balance of the
         period remaining under the term of this Agreement, or (y) two (2)
         years;

reduced, in any case however, by the amount of any payments made to such
Employee under the coverage then afforded to the Employee by the Company's
disability benefit plan in effect at the time such disability determination is
made.  The Employee shall, during such disability and until the effective date
of the termination of this Agreement and of payments hereunder by the Company
to the Employee, continue to enjoy all other applicable benefits of employment
that would otherwise pertain to continued employment on part-time status
pursuant to this Agreement.

         H.      Return of Property.  Upon termination of the Employee's
employment under this Agreement, however brought about, the Employee (or his
representatives) shall promptly deliver and return to the Company all the
Company's property including, but not limited to, credit cards,





                                      -12-
<PAGE>   13
manuals, customer lists, financial data, letters, notes, notebooks, reports and
copies of any of the above, and any Protected Information (as defined in
Section 7) which is in the possession or under the control of the Employee
except such property as may be necessary for the former Employee to continue
his duties, if any, as an "affiliate" which the Company may expressly direct
the former Employee to keep in his possession; and upon the termination of his
status as an "affiliate", the former Employee shall promptly deliver and return
all such property to the Company.

5.       OTHER EMPLOYEE RIGHTS

         A.      The Employee shall be entitled to (i) participate in the
Company's pension, group life, medical, dental, accidental death, or disability
insurance, thrift, savings, deferred compensation, incentive compensation,
stock option, unit or award plans, vacation plans, automobile allowances and
all other Company benefit plans, fringe benefits, allowances and accommodations
of employment (including, but only as approved from time to time by the Chief
Executive Officer of the Company, club memberships and dues, business and
professional societies, etc.), accommodations and allowances as are from time
to time generally available or applicable to the Company's principal executive
officers (but in no event less than are currently available to the Employee),
and (ii) annual vacations in accordance with the vacation policy established by
the Company for the Company's principal executive officers (but in no event
less than currently available to the Employee) during which time his applicable
compensation shall be paid in full.

         B.      The Employee is authorized (to the same extent and in the same
manner as the Company's other principal executive officers are authorized) to
incur reasonable business expenses while on active or part-time status as an
employee of the Company, including expenses for meals, entertainment, hotel and
air travel, telephone, automobile, dues, club expenses, fees, and similar items
(and shall be entitled to incur such reasonable business expenses, determined
commensurate with the extent of his consultation hereunder, while an
"affiliate" of the Company).  The Company shall either pay directly or promptly
reimburse the Employee for such expenses upon the presentment by the Employee
from time to time of an itemized accounting (as reasonably required by the
Company's policies) of such expenditures for which reimbursement is sought.

         C.      The Employee shall, while on active status, be provided by the
Company with office space, furnishings and facilities, reserved parking,
secretarial and administrative assistance, supplies and equipment commensurate
with the size and quality of that which is provided from time to time to the
Company's principal executive officers.

         D.      The Employee shall be granted options to purchase 100,000
shares of common stock, $.01 par value, of the Company under the Company's 1993
Stock Incentive Plan. The price, terms, and conditions of such options shall be
in accordance with the provisions of the 1993 Stock Incentive Plan.





                                      -13-
<PAGE>   14
         E.      The Company will reimburse the Employee for all direct
commuting and moving costs incurred by the Employee in relocating to Dallas,
Texas upon submission of an appropriately documented request for reimbursement
in a form and manner consistent with the Company's expense reporting policy.
Reimbursement can be claimed on a timeframe that suits the Employee's personal
requirements (i.e., weekly, bi-weekly, or monthly).  The Company will also
reimburse the Employee for all direct real estate fees and transaction costs
incurred by the Employee in disposing of the Employee's current residence and
purchasing a new principal residence in Dallas, Texas.  In addition, the
Company will pay the Employee an amount equal to the Employee's individual U.S.
federal income taxes associated with the Company's reimbursement of the
Employee's relocation expenses.

6.       COVENANT NOT TO COMPETE

         A.      The Employee recognizes that in each of the highly competitive
businesses in which the Company is engaged, personal contact is of primary
importance in securing new customers and in retaining the accounts and goodwill
of present customers and protecting the business of the Company.  The Employee,
therefore, agrees that at all times during the term of his employment hereunder
and for a period of two (2) years after the termination of his employment
hereunder, howsoever brought about, he will not, within 100 miles of

                   (i)    the principal place of business of the Company,

                  (ii)    the principal place of business of any corporation or
         other entity owned, controlled by (or otherwise affiliated with) the
         Company by which he may also be employed or served by him a an officer
         or director, or

                 (iii)    any other geographic location in which the Employee
         has specifically represented the interests of the Company or such
         other affiliated entity, in any of the businesses described in
         subsections (a) through (d) below during the twelve (12) months prior
         to the termination of this Agreement, as principal agent, partner,
         employee, consultant, distributor, dealer, contractor, broker or
         trustee or through the agency of any corporation, partnership,
         association or agent or agency, engage directly or indirectly, in any
         business of (a) rubbish, garbage, paper, textile wastes, chemical or
         hazardous wastes, liquid or other waste collection, interim storage,
         transfer, recovery, processing, recycling, marketing or disposal, (b)
         engineering or design, construction, or operation of any plant,
         facility or other structure having as its primary purpose the mass
         burning of solid or liquid waste with or without any intended efforts
         to recover from such wastes, energy, steam, ash, fly ash or other
         constituents of the waste stream, regardless of whether such
         constituents have any value, (c) manufacturing, selling, leasing or
         distributing machinery, equipment or products used or produced in
         connection with the activities described in subsections (a) or (b)
         above, or (d) any other material business engaged in by the Company,
         and shall not be the owner of more than 1% of the outstanding capital
         stock of any corporation (other than the Company), or an officer,
         director or employee of any





                                      -14-
<PAGE>   15
         corporation (other than the Company or a corporation affiliated with
         the Company), or a member or employee of any partnership, or an owner,
         investor, lender, agent, consultant, distributor, dealer, contractor,
         broker or employee of any other business which conducts a business
         described in subsections (a), (b), (c) and (d) above, within the
         territory described above.

         B.      The Employee agrees that during the term of his employment
under this Agreement and for a period of two (2) years after the termination of
the Employee's employment under this Agreement, he will not directly or
indirectly (i) induce any customers of the Company or corporations affiliated
with the Company to patronize any similar business that competes with any
material business of the Company; (ii) canvass, solicit, or accept any similar
business from any customer of the Company or corporations affiliated with the
Company; (iii) request or advise any customers of the Company or corporations
affiliated with the Company to withdraw, curtail, or cancel such customer's

employee of the Company or any corporation affiliated with the Company to leave
the employ of the Company or such other corporation to accept employment with
or compensation from the Employee or any such person, firm, association, or
corporation without the prior written consent of the Company.  The Employee
further agrees that he shall not engage in any pattern of conduct that involves
the making or publishing of written or oral statements or remarks (including,
without limitation, the repetition or distribution of derogatory rumors,
allegations, negative reports or comments) which are disparaging, deleterious
or damaging to the integrity, reputation or good will of the Company, its
management, or of management of corporations affiliated with the Company.

         C.      If the provisions of this Section 6 are violated, in whole or
in part, the Company shall be entitled, upon application to any court of proper
jurisdiction, to a temporary restraining order or preliminary injunction
(without the necessity of posting any bond with respect thereto) to restrain
and enjoin the Employee from such violation without prejudice to any other
remedies the Company may have at law or in equity.  Further, in the event that
the provisions of this Section 6 should ever be deemed to exceed the time,
geographic or occupational limitations permitted by the applicable laws, the
Employee and the Company agree that such provisions shall be and are hereby
reformed to the maximum time, geographic or occupational limitations permitted
by the applicable laws.  The provisions of this Section 6 shall survive the
termination of the Employee's employment or expiration or termination of this
Agreement.

7.               CONFIDENTIAL INFORMATION - INTELLECTUAL PROPERTY

         A.      The Employee recognizes and acknowledges that he has had and
will continue to have access to various confidential or proprietary information
concerning the Company and corporations affiliated with the Company of a
special and unique value which may include,





                                      -15-
<PAGE>   16
without limitation, (i) books and records relating to operation, finance,
accounting, sales, personnel and management, (ii) policies and matters relating
particularly to operations such as customer service requirements, costs of
providing service and equipment, operating costs and pricing matters, and (i)
various trade or business secrets, including business opportunities, marketing
or business diversification plans, business development and bidding techniques,
methods and processes, financial data and the like (collectively, the
"Protected Information").

         B.      The Employee agrees, therefore, that he will not at any time,
either while employed by the Company or afterwards, knowingly make any
independent use of, or knowingly disclose to any other person or organization
(except as authorized by the Company) any of the Protected Information.

         C.      In the event of a breach or threatened breach by the Employee
of the provisions of this Section 7, the Employee agrees that Company shall be
entitled to a temporary restraining order or a preliminary injunction (without
the necessity of the Company posting any bond in connection therewith)
restraining the Employee from using or disclosing, in whole or in part, such
Protected Information.  Nothing herein shall be construed as prohibiting the
Company from pursuing any other remedies available to it for such breach or
threatened breach, including the recovery of damages from the Employee.

         D.      The Employee shall disclose promptly to the Company any and
all conceptions and ideas for inventions, improvements, and valuable
discoveries, whether patentable or not, which are conceived or made by the
Employee solely or jointly with another during the period of employment on
active status or within one (1) years thereafter and which pertain primarily to
the material business activities of the Company and the Employee hereby assigns
and agrees to assign all his interests therein to the Company or to its
nominee; whenever requested to do so by the Company, the Employee shall execute
any and all applications, assignments or other instruments which the Company
shall deem necessary to apply for and obtain Letters of Patent of the United
States or any foreign country or to otherwise protect the Company's interest
therein.  These obligations shall continue beyond the termination of employment
with respect to inventions, improvements, and valuable discoveries, whether
patentable or not, conceived, made or acquired by the Employee during the
period of employment or within one(1) year thereafter, and shall be binding
upon the Employee's assigns, executors, administrators and other legal
representatives.

8.               EMPLOYEE CONDUCT

         A.      The Employee represents and agrees with the Company that he
will make no disbursement or other payment of any kind or character out of the
compensation paid or expenses reimbursed to him pursuant hereto or with any
other fund, which contravene, in any material respect, any policy of the
Company or, in any material respect, any applicable statute or rule, regulation
or order of any jurisdiction, foreign or domestic.  The Employee further agrees
to indemnify and save harmless the Company from any liabilities, obligations,
claims, penalties, fines or losses resulting from any unauthorized or unlawful
acts of the Employee which





                                      -16-
<PAGE>   17
contravene in any material respect any policy of the Company or any statute,
rule, regulation or order of any jurisdiction, foreign or domestic, applicable
to the Employee or the Company.  The provisions of this Section 8 shall survive
the dissolution or termination of the Employee's employment under this
Agreement.

         B.      The Employee acknowledges that he has been furnished with a
current copy of the policy and procedures manual of the Company, that he has
read and understands such policies and procedures set forth in such manual,
that he understands such policies and procedures (and will read and become
familiar with any revisions or supplements to this manual) are applicable to
the Employee in the performance of his duties and job performance for the
Company, and that he agrees to observe in all material respects the Company's
policies and procedures in the conduct by the Employee of his employment duties
for the Company.

         C.      The Employee agrees to disclose honestly and fully all
information and documentation in his possession concerning all transactions or
events relating to or affecting the Company or any entity owned, controlled (or
otherwise affiliated) by the Company, as and to the extent such information or
documentation is requested by the Company or the authorized representatives
thereof; provided that if the Employee indicates to the Company that the
information or documentation requested is privileged, confidential or
personally sensitive, appropriate steps will be taken to attempt to protect
such privilege, confidentiality or privacy to the extent possible consistent
with the ethical or legal obligations applicable to the Company, but neither
such assertions by the Employee nor the undertakings attempted by the Company
with respect thereto shall qualify the unconditional disclosure obligation of
the Employee set forth above.

9.       GENERAL PROVISIONS

         A.      In case any one or more of the provisions of this Agreement
shall, for any reason, be held or found by final judgment of a court of
competent jurisdiction to be invalid, illegal or unenforceable in any respect
(i) such invalidity, illegality or unenforceability shall not affect any other
provisions of this Agreement, (ii) this Agreement shall be construed as if such
invalid, illegal or unenforceable provision had never been contained herein
(except that this subsection (ii) shall not prohibit any modification allowed
under Section 6 hereof), and (iii) if the effect of a holding or finding that
any such provision is either invalid, illegal or unenforceable is to modify to
the Employee's detriment, reduce or eliminate any compensation, reimbursement,
payment, allowance or other benefit to the Employee intended by the Company and
Employee in entering into this Agreement, the Company shall promptly negotiate
and enter into an agreement with the Employee containing alternative provisions
(reasonably acceptable to the Employee), that will restore to the Employee (to
the extent lawfully permissible) substantially the same economic, substantive
and income tax benefits the Employee would have enjoyed had any such provision
of this Agreement been upheld as legal, valid and enforceable.  Failure to
insist upon strict compliance with any provision of this Agreement shall not be
deemed a waiver of such provision or of any other provision of this Agreement.

<PAGE>   18

(together with any attachments hereto), which has been executed in duplicate
and agrees that, with respect to the subject matter hereof, it is the entire

waived unless such amendment, modification or waiver shall be agreed to in
writing and signed by the Employee and by a person duly authorized by the
Compensation Committee.

         E.      No right to or interest in any compensation or reimbursement
payable hereunder shall be assignable or divisible by the Employee; provided,
however, that this provision shall not preclude the Employee from designating
one or more beneficiaries to receive any amount that may be payable after his
death and shall preclude his executor or administrator from assigning any right
hereunder to the person or person entitled thereto.

         F.      The headings of Sections and subsection hereof are included
solely for convenience of reference and shall not control the meaning or
interpretation of any of the provisions of this Agreement.

         G.      (i)      Company consents with respect to any action, suit or
         other legal proceeding pertaining directly to this Agreement or to the

         purpose.  Company irrevocably (i) agrees that any such suit, action or

         courts.

                 (ii)     This Agreement shall be construed in accordance with
         and governed for all purposes by the laws of the State of Texas.

         H.      This Agreement may not be assigned, partitioned, subdivided,
pledged, or hypothecated in whole or in part without the express prior written
consent of the Employee and





                                      -18-

Company.  This Agreement shall not be terminated either by the voluntary or
involuntary dissolution or the winding up of the affairs of the Company, or by
any merger or consolidation wherein the Company is not the surviving
corporation, or by any transfer of all or substantially all of the Company's
assets on a consolidated basis.  In the event of any such merger, consolidation

determined to have been paid or payable or reimbursed or reimbursable to the
Employee until such amounts and any interest accrued thereon are finally and
fully paid, provided, however, that in no event shall the amount of interest
contracted for, charged or received hereunder exceed the maximum non-usurious
amount of interest allowed by applicable law.

         J.      The Company agrees with the Employee that, except to the
extent required by law, it will not make or publish, without the express prior
written consent of the Employee, any written or oral statement concerning the
