1.   GRANT OF OPTION. The Plan Administrator of the Company hereby grants to the
     Optionee named in this Agreement (the "Optionee") an option (the "Option")
     to purchase the number of Shares, as set forth in this Agreement, at the
     exercise price per share set forth in the Agreement (the "Option Price Per
     Share"), subject to the terms and conditions of the Plan, which is
     incorporated herein by reference. Subject to Section 15 (c) of the Plan, in
     the event of a conflict between the terms and conditions of the Plan and
     the terms and conditions of this Stock Option Agreement, the terms and
     conditions of the Plan shall prevail.

          If designated in the Agreement as an Incentive Stock Option ("ISO"),
     this Option is intended to qualify as an Incentive Stock Option under
     Section 422 of the Code. However, if this Option is intended to be an
     Incentive Stock Option, to the extent that it exceeds the $100,000 rule of
     Code Section 422(d) it shall be treated as a Non-Qualified Stock Option
     ("Non-Statutory Stock Option "or "NQ")

2.   VESTING SCHEDULE. This option may be exercised, in whole or in part, in
     accordance with the following schedule:

3.   TERMINATION PERIOD. This Option may be exercised for one (1) year after the
     Optionee ceases to be a Service Provider. Upon the death or disability of
     the Optionee, this Option may be exercised for one year after Optionee
     ceases to be a Service Provider. Upon a qualified Retirement, the Option
     will continue to vest for an additional twelve (12) months following the
     Optionee's date of retirement. The Optionee will then have thirty (30) days
     following such 12-month period to exercise the Option. In no event shall
     this Option be exercised later than the Expiration Date as provided above.
     Retirement means an Optionee's ceasing to be Service Provider on or after
     the date when the sum of (i) the Optionee's age (rounded down to the
     nearest whole month), plus (ii) the number of years (rounded down to the
     nearest whole month) that the Optionee has provided services to the Company
     equals or is greater than seventy-five (75).

4.   EXERCISE OF OPTION. The option is exercisable during its term in accordance
     with the Vesting Schedule set out in the Agreement and the applicable
     provision of the Plan and this Agreement. An option is exercisable by
     completing transaction through Company's captive broker assisted
     transactions via voice response system or Internet secured transaction
     system.

          The Option shall be deemed to be exercised upon receipt by the Company
     of such fully executed Exercise accompanied by such aggregate Exercise
     Price. No shares shall be issued pursuant to the exercise of this Option
     unless such issuance and exercise complies with Applicable Laws. Assuming
     such compliance, for income tax purposes the Exercised Shares shall be
     considered transferred to the Optionee on the date the Option is exercised
     with respect to such Exercised Shares.

<PAGE>

5.   METHOD OF PAYMENT. Payment of the aggregate Exercise Price shall be by any
     of the following, or a combination thereof, at the election of the
     Optionee:

     (a)  Cash; or

     (b)  Check; or

     (c)  Consideration received by the Company under a cashless exercise
          program implemented by the Company in connection with the Plan; or

     (d)  Surrender of other shares which (i) in the case of Shares acquired
          upon exercise of an option, have been owned by the Optionee for more
          than six (6) months on the date of surrender, and (ii) have a Fair
          Market Value on the date of the surrender equal to the aggregate
          Exercise Price of the Exercised Shares.

6.   WITHHOLDING TAXES. You are responsible for payment of any federal, state,
     local or other taxes which must be withheld upon the exercise of the
     Option, and you must promptly pay to the Company any such taxes. The
     Company and its subsidiaries are authorized to deduct from any payment owed
     to you any taxes required to be withheld with respect to the Shares. Refer
     to the Summary Plan Description for additional general tax consequences
     relating to the Exercise of the Option. This is intended to be a summary of
     tax consequences; the Optionee should consult a tax adviser before
     exercising this Option or disposing of the Shares.

7.   ENTIRE AGREEMENT; GOVERNING LAW. The Plan is incorporated herein by
     reference. The Plan and this Agreement constitute the entire agreement of
     the parties with respect to the subject matter hereof and supersede in
     their entirety all prior undertakings and agreements of the Company an
     Optionee with respect to the subject matter hereof, and may not be modified
     adversely to the Optionee's interest except by means of a writing signed by
     the Company and the Optionee. This agreement is governed by the internal
     substantive laws, but not the choice of law rules, of Delaware.

8.   NO GUARANTEE OF CONTINUED SERVICE. By receipt of this Agreement, the
     Optionee acknowledges and agrees that the vesting of shares pursuant to the
     vesting schedule hereof is earned only by continuing as a Service Provider
     at the will of the Company (and not through the act of being hired, being
     granted an option or purchasing shares hereunder). Optionee further
     acknowledges and agrees that this agreement, the transactions contemplated
     hereunder and the vesting schedule set forth herein do not constitute an
     express or implied promise of continued engagement as a Service Provider
     for the vesting period, for any period, or at all, and shall not interfere
     with Optionee's rights or the Company's right to terminate Optionee's
     relationship as a Service Provider at any time, with or without cause.

9.   AGREEMENT. Your receipt of the Option and this Agreement constitutes your
     agreement to be bound by the terms and conditions of this Agreement and the
     Plan. Your signature is not required in order to make this Agreement
     effective.

Exhibit 10.1

SECOND AMENDED AND RESTATED

EMPLOYMENT AGREEMENT

     This AMENDED AND RESTATED EMPLOYMENT AGREEMENT is effective as of the effective time of the
merger of Allied Waste Industries, Inc., a Delaware corporation into RS Merger Wedge, Inc., a
Delaware corporation and wholly-owned subsidiary of Republic Services, Inc., a Delaware corporation
(the “Merger”) pursuant to the Agreement & Plan of Merger dated as of June 22, 2008 (the “Effective
Time”), by and between Republic Services, Inc. (the “Company”) and JAMES E. O’CONNOR (“Employee”).

     Employee and the Company are parties to that Employment Agreement dated as of October 25,
2000, as amended by Amendment Number One, dated as of January 31, 2003, and Amendment Number Two,
dated as of October 10, 2006 and that Amended and Restated Employment Agreement dated as of
February 21, 2007 (the “2007 Employment Agreement, and collectively the Existing Employment
Agreement”).

     As of the date hereof, Employee continues to be an employee of the Company and is considered a
valued employee such that the Company desires to retain in accordance with the terms of the
Existing Employment Agreement.

     For making changes to the Existing Employment Agreement, including in connection with the
Merger, Employee and the Company desire to enter into this Second Amended and Restated Employment
Agreement (this “Agreement”).

     In consideration of the premises set forth above, the mutual representations, warranties,
covenants and agreements contained in this Agreement and other good and valuable consideration the
receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:

     1. Employment.

          (a) Retention. The Company agrees to employ and/or continue the employment of
Employee as its Chairman and Chief Executive Officer, and Employee agrees to accept such
employment, subject to the terms and conditions of this Agreement. The Company also agrees that
Employee shall continue to serve on the Company’s Board of Directors until the next annual meeting
of stockholders of the Company, and that he shall be nominated for election to the Board at each
annual meeting of the stockholders of the Company as long as this Agreement remains in effect.

          (b) Employment Period. This Agreement shall commence on the Effective Time and,
unless terminated in accordance with the terms of this Agreement shall continue in effect on a
rolling three-year basis, such that at any time during the term of this Agreement there will be
three years remaining (the “Employment Period”). Notwithstanding the evergreen nature of the

1

 

Employment Period, the Company may terminate Employee at any time in accordance with the
provisions of Section 3 of this Agreement.

          (c) Duties and Responsibilities. During the Employment Period, Employee shall serve
as Chairman and Chief Executive Officer and shall have such authority and responsibility and
perform such duties as may be assigned to him from time to time at the direction of the Board of
Directors of the Company, and in the absence of such assignment, such duties as are customary to
Employee’s office and as are necessary or appropriate to the business and operations of the
Company. During the Employment Period, Employee’s employment shall be full time and Employee shall
perform his duties honestly, diligently, in good faith and in the best interests of the Company and
shall use his best efforts to promote the interests of the Company. All executive officers of the
Company (except for the Chairman and the Vice Chairman) shall report to the Chief Executive
Officer, and Employee shall in such capacity have the authority and responsibility to assign
appropriate duties to such other executive officers as are necessary or appropriate for the
business and operations of the Company.

          (d) Other Activities. Except upon the prior written consent of the Company, Employee,
during the Employment Period, will not accept any other employment. Employee shall be permitted to
engage in any non-competitive businesses, not-for-profit organizations and other ventures, such as
passive real estate investments, serving on charitable and civic boards and organizations, and
similar activities, so long as such activities do not materially interfere with or detract from the
performance of Employee’s duties or constitute a breach of any of the provisions contained in
Section 7 of this Agreement.

     2. Compensation.

          (a) Base Salary and Adjusted Salary. In consideration for Employee’s services
hereunder and the restrictive covenants contained herein, Employee shall be paid an annual base
salary (the “Base Salary”) of $1,100,000, payable in accordance with the Company’s customary
payroll practices. With respect to the 2008 Fiscal Year, Base Salary shall be prorated by
multiplying the Base Salary by a fraction, the numerator of which is the number of days from the
Effective Time to December 31, and the denominator of which is 365. With respect to any Fiscal
Year during which Employee is employed by the Company for less than the entire Fiscal Year, the
Base Salary shall be prorated for the period during which the Employee is so employed.
Notwithstanding the foregoing, Employee’s annual Base Salary may be increased, but not decreased
(taking into account prior increases) without Employee’s consent at anytime and from time to time
to levels greater than the levels set forth in the preceding sentence at the discretion of the
Board of Directors of the Company to reflect merit or other increases. The term “Fiscal Year” as
used herein shall mean each period of twelve (12) calendar months commencing on January 1st of each
calendar year during the Employment Period and expiring on December 31st of such year.

          (b) Annual Awards. In addition to the Base Salary, Employee shall be eligible to
receive Annual Awards in an amount equal to a target of 130% of the Employee’s Base Salary in
effect for the Performance Period with respect to which such Annual Award is granted, as
established pursuant to the terms of the Company’s Executive Incentive Plan, as amended (the

2

 

“Executive Incentive Plan”). The Annual Award shall be based on the achievement of such
Performance Goals as are established by the Compensation Committee of the Board of Directors
pursuant to the Executive Incentive Plan. The achievement of said Performance Goals shall be
determined by the Compensation Committee of the Board of Directors. Except as otherwise provided
in Sections 3 and 25, with respect to any Fiscal Year during which Employee is employed by the
Company for less than the entire Fiscal Year, the Annual Award shall be prorated for the period
during which Employee was so employed. The Annual Award shall be payable within sixty (60) days
after the end of the Company’s Fiscal Year. To the extent of any conflict between the provisions
of this Agreement and the Executive Incentive Plan, the terms of this Agreement shall control.

          (c) Merit and Other Bonuses. Employee shall be entitled to such other bonuses as may
be determined by the Board of Directors of the Company or by a committee of the Board of Directors
as determined by the Board of Directors, in its sole discretion.

          (d) Existing Stock Options and Shares of Restricted Stock. The Company has issued to
Employee options to purchase shares of the Company’s Common Stock pursuant to the terms of various
Option Agreements and the terms of the Company’s 2007 Stock Incentive Plan and 2007 Stock Incentive
Plan (the “Outstanding Option Grants”). The Company has also granted to Employee restricted shares
of the Company’s Common Stock pursuant to the terms of various Executive Restricted Stock
Agreements and the terms of the Company’s 1998 Stock Incentive Plan (the “Outstanding Restricted
Stock Grants”). The options issued or to be issued under the Outstanding Option Grants shall
continue to be subject to the terms of the Option Agreements, except to the extent otherwise
provided for in this Agreement. The shares of restricted stock granted or to be granted under the
Outstanding Restricted Stock Grants shall continue to be subject to the terms of the Executive
Restricted Stock Agreements, except to the extent otherwise provided for in this Agreement.

          (e) Other Stock Options. Employee shall be entitled to participate and receive option
grants under the 2007 Stock Incentive Plan and such other incentive or stock option plans as may be
in effect from time-to-time, as determined by the Board of Directors of the Company.

          (f) Other Compensation Programs. Employee shall be entitled to participate in the
Company’s incentive and deferred compensation programs and such other programs as are established
and maintained for the benefit of the Company’s employees or executive officers, subject to the
provisions of such plans or programs.

          (g) Health Insurance. The Company shall pay for Employee’s and his family’s health
insurance including without limitation comprehensive major medical and hospitalization coverage
including dental and optical coverage under all group medical plans from time to time in effect for
the benefit of the Company’s employees or executive officers.

          (h) Life Insurance. The Company shall purchase and maintain in effect one or more
term insurance policies on the life of Employee in an aggregate amount not less than two times

3

 

his Base Salary in effect from time to time during the term of employment. The beneficiary of such
policy shall be the person or persons who Employee designates in writing to the Company.

          (i) Disability Insurance. The Company shall pay for Employee to participate in the
Company’s disability insurance in effect from time to time. The Company shall pay for the maximum
coverage commercially available. To the extent the Company does not have a disability insurance
plan or other retirement plan, then the Company shall arrange, at its expense, for Employee to
participate in such plan.

          (j) Other Benefits. During the term of this Agreement, Employee shall also be
entitled to participate in any other health insurance programs, life insurance programs, disability
programs, stock option plans, bonus plans, pension plans and other fringe benefit plans and
programs as are from time to time established and maintained for the benefit of the Company’s
employees or executive officers, subject to the provisions of such plans and programs.

          (k) Expenses. Employee shall be reimbursed for all out-of-pocket expenses reasonably
incurred by him on behalf of or in connection with the business of the Company, pursuant to the
normal standards and guidelines followed from time to time by the Company. Notwithstanding
anything herein to the contrary or otherwise, except to the extent any expense or reimbursement
described in this Section 2(k) does not constitute a “deferral of compensation” within the meaning
of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), any expense or
reimbursement described in this Section 2(k) shall meet the following requirements: (i) the amount
of expenses eligible for reimbursement provided to Employee during any calendar year will not
affect the amount of expenses eligible for reimbursement or in-kind benefits provided to Employee
in any other calendar year, (ii) the reimbursements for expenses for which Employee is entitled to
be reimbursed shall be made on or before the last day of the calendar year following the calendar
year in which the applicable expense is incurred, (iii) the right to payment or reimbursement on
in-kind benefits hereunder may not be liquidated or exchanged for any other benefit, and (iv) the
reimbursements shall be made pursuant to objectively determinable and nondiscretionary Company
policies and procedures regarding such reimbursement of expenses.

          (l) Long Term Awards. On April 26, 2001, the Board of Directors adopted the Republic
Services, Inc. Long Term Incentive Plan, effective January 1, 2001 to provide for long term
incentive cash grants for specific employees of the Company, including Employee. Effective January
1, 2003, the Long Term Incentive Plan was amended, restated and renamed the Executive Incentive
Plan to provide not only for long term incentive cash grants but also to include the Annual Awards
referred to above. Employee has participated in the Long Term Incentive Plan and the Executive
Incentive Plan since inception, and Employee shall be entitled to continue to participate in the
Executive Incentive Plan (or any successor plan maintained by the Company) for purposes of
receiving Long Term Awards pursuant to the terms of this Agreement and the Executive Incentive Plan
(or such successor plan).

          (m) Synergy Incentive Plan. A schedule of the maximum award that the Employee is
eligible to receive under the Synergy Incentive Plan is attached as Schedule 2(m), subject to
shareholder approval of amendments to the Executive Incentive Plan, and provided

4

 

Employee has
waived his right to terminate for Good Reason pursuant to Section 3(c)(vi) or he has not terminated
employment and 7 days has elapsed after the 2009 Annual Meeting of Shareholders (the “Acceptance
Date”). Awards under the Synergy Incentive Plan shall not be considered Annual Awards, Long Term
Awards, or equity awards or otherwise taken into account for purposes of Sections 3, 4 or 25 of
this Agreement, but instead, such awards shall be governed by the terms of the Synergy Incentive
Plan.

          (n) Insurance. At all times during the term of this Agreement, and for such
additional periods as are provided for in this Agreement, the Employee shall be covered under the
Company’s directors’ and officers’ liability insurance.

          (o) Deferred Compensation Credits. The Company shall credit $2,250,000 to Employee’s
Annual Account as part of the Company Contribution Account pursuant to the Company’s Deferred
Compensation Plan (“Additional Company Contribution Account”) on January 1, 2010, provided that
Employee is employed on such date (“Grant Date”). The Additional Company Contribution Account, as
adjusted under the Deferred Compensation Plan shall be immediately vested on the Grant Date and the
Employee shall receive the Additional Company Contribution Account, as adjusted, in accordance with
the terms of the Deferred Compensation Plan.

     3. Termination.

          (a) For Cause. The Company shall have the right to terminate this Agreement and to
discharge Employee for Cause (as defined below), at any time during the term of this Agreement.
Termination for Cause shall mean, during the term of this Agreement, (i) Employee’s willful and
continued failure to substantially perform his duties after he has received written notice from the
Company identifying the actions or omissions constituting willful and continued failure to perform,
(ii) Employee’s conduct that would constitute a crime under federal or state law, (iii) Employee’s
actions or omissions that constitute fraud, dishonesty or gross misconduct, (iv) Employee’s breach
of any fiduciary duty that causes material injury to the Company, (v) Employee’s breach of any duty
causing material injury to the Company, (vi) Employee’s inability to perform his material duties to
the reasonable satisfaction of the Company due to alcohol or other substance abuse, or (vii) any
violation of the Company’s policies or procedures involving discrimination, harassment, substance
abuse or work place violence. Any termination for Cause pursuant to this Section shall be given to
Employee in writing and shall set forth in detail all acts or omissions upon which the Company is
relying to terminate the Employee for Cause.

          Upon any determination by the Company that Cause exists to terminate Employee, the Company
shall cause a special meeting of the Board of Directors to be called and held at a time mutually
convenient to the Board of Directors and Employee, but in no event later than ten (10) business
days after Employee’s receipt of the notice that the Company intends to terminate Employee for
Cause. Employee shall have the right to appear before such special meeting of the Board of
Directors with legal counsel of his choosing to refute such allegations and shall have a
reasonable period of time to cure any actions or omissions which provide the Company with a basis
to terminate Employee for Cause (provided that such cure period shall not exceed 30 days). A

5

 

majority of the members of the Board of Directors must affirm that Cause exists to terminate
Employee. In the event the Company terminates Employee for Cause, the Company shall only be
obligated to continue to pay in the ordinary and normal course of its business to Employee his Base
Salary plus accrued but unused vacation time through the termination date and the Company shall
have no further obligations to Employee under this Agreement from and after the date of
termination.

          (b) Resignation by Employee Without Good Reason. If Employee shall resign or
otherwise terminate his employment with the Company at anytime during the term of this Agreement,
other than for Good Reason (as defined below), Employee shall only be entitled to receive his
accrued and unpaid Base Salary and unused vacation time through the termination date, and the
Company shall have no further obligations under this Agreement from and after the date of
resignation.

          (c) Termination by Company Without Cause and by Employee For Good Reason. At any time
during the term of this Agreement, (i) the Company shall have the right to terminate this Agreement
and to discharge Employee without Cause effective upon delivery of written notice to Employee, and
(ii) Employee shall have the right to terminate this Agreement for Good Reason effective upon
delivery of written notice to the Company. For purposes of this Agreement, “Good Reason” shall
mean: (i) the Company has materially reduced the duties and responsibilities of Employee to a
level not appropriate for an officer of a publicly-traded company holding the position provided for
in Section 1(a), (ii) the Company has breached any material provision of this Agreement and has not
cured such breach within 30 days of receipt of written notice of such breach from Employee, (iii)
Company has reduced Employee’s annual Salary by more than 10% from the prior Fiscal Year (nothing
in this clause implies that the Company may reduce Employee’s Salary below the levels provided for
in Section 2(a)), (iv) the Company has terminated Employee’s participation in one or more of the
Company’s sponsored benefit or incentive plans and no other executive officer has had his
participation terminated, (v) a failure by the Company (1) to continue any bonus plan, program or
arrangement in which Employee is entitled to participate (“Bonus Plans”), provided that any such
Bonus Plans may be modified at the Company’s discretion from time to time but shall be deemed
terminated if (x) any such plan does not remain substantially in the form in effect prior to such
modification and (y) if plans providing Employee with substantially similar benefits are not
substituted therefor (“Substitute Plans”), or (2) to continue Employee as a participant in the
Bonus Plans and Substitute Plans on at least a basis which is substantially the same as to
potential amount of the bonus Employee participated in prior to any change in such plans or awards,
in accordance with the Bonus Plans and the Substitute Plans (a plan shall be considered to be on a
basis substantially the same as another if the potential amount payable thereunder is at least 90%
of the potential amount payable under the other plan), (vi) Employee’s office is relocated by the
Company to a location which is not located within the Florida counties of Miami-Dade, Broward or
Palm Beach, or (vii) the Company’s termination without Cause of the continuation of the Employment
Period provided in this Agreement; provided that (vi) shall continue to apply for 7 days after the
2009 Annual Meeting of Shareholders of the Company irrespective of whether the Employee
relocates to the Arizona county of Maricopa, and thereafter the Arizona county of Maricopa
shall be substituted for the Florida counties of Miami-Dade, Broward or Palm Beach in

6

 

such Section.
Notwithstanding the foregoing, the Employee’s termination of employment pursuant to this
Agreement (other than with respect to (vi) up to 7 days after the 2009 Annual Meeting of
Shareholders of the Company) shall not be effective unless (i) the Employee delivers a written
notice setting forth the details of the occurrence giving rise to the claim of termination for Good
Reason within a period not to exceed 90 days of its initial existence and (ii) the Company fails to
cure the same within a thirty (30) day period. Upon any such termination by the Company without
Cause, or by Employee for Good Reason, (i) the Company shall pay to Employee all of Employee’s
accrued but unpaid Base Salary and accrued but unused vacation time through the date of termination
in a lump sum within sixty (60) days of termination; (ii) the Company shall pay to Employee Base
Salary for three (3) years from the date of termination when and as Base Salary would have been due
and payable hereunder but for such termination; (iii) the Company shall continue to pay or provide
for Employee all health benefits in which Employee was entitled to participate at any time during
the 12-month period prior to the date of termination, until the earliest to occur of the third
anniversary of the date of termination, Employee’s death, or the date on which Employee becomes
covered by a comparable health benefit plan by a subsequent employer; provided, however, that in
the event that Employee’s continued participation in any health benefit plan of the Company is
prohibited, the Company will arrange to provide Employee with benefits substantially similar to
those which Employee would have been entitled to receive under such plan for such period on a basis
which provides Employee with no additional after tax cost; (iv) all stock option grants or
restricted stock grants, whether or not part of the Outstanding Option Grant or any options issued
during the term of this Agreement, will immediately vest and any such options will remain
exercisable for the lesser of the unexpired term of the option without regard to the termination of
Employee’s employment or three (3) years from the date of termination of employment; (v) all Annual
Awards shall vest and be paid on a prorated basis in an amount equal to the Annual Awards payment
that the Compensation Committee of the Board of Directors determines would have been paid to
Employee pursuant to the Executive Incentive Plan had Employee’s employment continued to the end of
the Performance Period, multiplied by a fraction, the numerator of which is the number of completed
months of employment during such Performance Period and the denominator of which is the total
number of months in the Performance Period, within sixty (60) days after the end of the Company’s
Fiscal Year; (vi) all Long Term Awards shall vest and be paid on a prorated basis in an amount
equal to (x) the maximum Long Term Awards that would have been paid to Employee pursuant to the
Executive Incentive Plan had Employee’s employment continued to the end of the Performance Periods
established under the Executive Incentive Plan for award periods beginning on or before January 1,
2009 and (y) the Long Term Awards payment that the Compensation Committee of the Board of Directors
determines would have been paid to Employee pursuant to the Executive Incentive Plan had Employee’s
employment continued to the end of the Performance Period for award periods beginning after January
1, 2009, in each case, multiplied by a fraction, the numerator of which is the number of completed
months of employment during such Performance Period and the denominator of which is the total
number of months in the Performance Period, within sixty (60) days after the end of the Company’s
Fiscal Year in which the Performance Period ends; and (vii) as of the termination date Employee
shall be paid, in accordance with the Deferred Compensation Plan and
any elections thereunder, the balance of all amounts credited or eligible to be credited to
Employee’s deferred compensation account (including all Company contributions, whether or not
vested, other than the Additional Company Contribution Account solely in the event that such
termination occurs

7

 

prior to the Grant Date), plus, solely with respect to such termination prior to
the Acceptance Date, for all such amounts credited or eligible to be credited to such account based
upon Company’s performance on or before December 31, 2006 ( herein referred to as the “December 31,
2006 deferral amount”) whether or not such amount is actually credited to such account prior to or
after such date, a gross up payment to reimburse Employee for all income and other taxes imposed
with respect to the payment of such amounts and all income and other taxes arising as a result of
said gross up payment such that the payment of such December 31, 2006 deferral amount of Employee
is made to Employee free of all taxes thereon whatsoever (collectively, the foregoing consideration
payable to Employee shall be referred to herein as the “Severance Payment”). In the event that
such termination by the Company without Cause or by the Employee for Good Reason occurs within the
first two years of the Merger and before the Acceptance Date, (i) the Employee shall also receive
the product of three multiplied by the maximum amount of the Annual and Long Term Awards that the
Employee would have been eligible for under the Executive Incentive Plan with respect to the Fiscal
Year in which such termination occurs, in a lump sum within sixty (60) days of termination and (ii)
Employee will not be required to repay any Relocation Expenses pursuant to the Relocation Plan
(Level 4) which are paid or reimbursed in connection with Employee’s relocation to Arizona. Other
than the Severance Payment and additional benefits described herein, the Company shall have no
further obligation to Employee except for the obligations set forth in Sections 10 and 17 of this
Agreement after the date of such termination; provided, however, that Employee shall only be
entitled to continuation of the Severance Payment as long as he is in compliance with the
provisions of Sections 7, 8, 10 and 11 of this Agreement.

          (d) Disability of Employee. This Agreement may be terminated by the Company upon the
Disability of Employee. “Disability” shall mean any mental or physical illness, condition,
disability or incapacity which prevents Employee from reasonably discharging his duties and
responsibilities under this Agreement for a period of 180 consecutive days. In the event that any
disagreement or dispute shall arise between the Company and Employee as to whether Employee suffers
from any Disability, then, in such event, Employee shall submit to the physical or mental
examination of a physician licensed under the laws of the State of Arizona, who is mutually
agreeable to the Company and Employee, and such physician shall determine whether Employee suffers
from any Disability. In the absence of fraud or bad faith, the determination of such physician
shall be final and binding upon the Company and Employee. The entire cost of such examination
shall be paid for solely by the Company. In the event the Company has purchased Disability
insurance for Employee, Employee shall be deemed disabled if he is completely (fully) disabled as
defined by the terms of the Disability policy. Disability shall not be deemed to occur unless it
constitutes a “disability,” as such term is defined in Code Section 409A. In the event that at
any time during the term of this Agreement Employee shall suffer a Disability and the Company
terminates Employee’s employment for such Disability, such Disability shall be considered to be a
termination by the Company without Cause or a termination by Employee for Good Reason and the
Severance Payment shall be paid to Employee to the same extent and in the same manner as provided
for in paragraph (c) above, except that (i) to the extent any Awards have been granted under
the Executive Incentive Plan, but, as of the date of such termination, have not been determined to
be earned pursuant to the terms of the Plan, Employee shall be paid, within thirty (30) days
following the date of Employee’s termination due to his Disability, an amount with respect to each

8

 

such open Award which is equal to the full target amount that the Compensation Committee of the
Board of Directors was authorized to cause to be paid to Employee pursuant to the Executive
Incentive Plan had his or her employment continued through the end of the Performance Period
related to such Award and had all Performance Goals been met, (ii) payments of Annual Salary shall
be mitigated by payments under Company-sponsored disability payments.

          (e) Death of Employee. If during the term of this Agreement Employee shall die, then
the employment of Employee by the Company shall automatically terminate on the date of Employee’s
death. In such event, Employee’s death shall be considered to be a termination by the Company
without Cause or a termination by Employee for Good Reason and the Severance Payment shall be paid
to Employee’s personal representative or estate to the same extent and in the same manner as
provided for in paragraph (c) above without mitigation for any insurance policies other benefits
held by Employee, except that to the extent any Awards have been granted under the Plan, but, as of
the date of such termination, have not been determined to be earned pursuant to the terms of the
Executive Incentive Plan, Employee’s beneficiary or estate shall be paid, within thirty (30) days
following the date of Employee’s death, an amount with respect to each such open Award which is
equal to the full target amount that the Compensation Committee of the Board of Directors was
authorized to cause to be paid to Employee pursuant to the Executive Incentive Plan had his or her
employment continued through the end of the Performance Period related to such Award and had all
Performance Goals been met. Once such payments have been made to Employee’s personal
representative, beneficiary or estate, as the case may be, the Company shall have no further
obligations under this Agreement to said personal representative, beneficiary or estate, or to any
heirs of Employee.

     4. Change of Control.

          (a) Termination Rights. Notwithstanding the provisions of Section 2 and Section 3 of
this Agreement, in the event that there shall occur a Change of Control (as defined below) of the
Company and within two years after such Change of Control Employee’s employment hereunder is
terminated by the Company without Cause or by Employee for Good Reason, then the Company shall be
required to pay to Employee (i) the Severance Payment provided in Section 3(c), except that the
Severance Payment shall be paid in a single lump sum in full within sixty (60) days of termination
if termination occurs within two years after such Change of Control, and (ii) the product of three
(3) multiplied by the target amount of the Annual Awards and Long Term Awards that Employee would
have been eligible for under the Executive Incentive Plan with respect to the Fiscal Year in which
such termination occurs, in a single lump sum within sixty (60) days of termination. To the extent
that payments are owed by the Company to Employee pursuant to this Section 4, they shall be made in
lieu of payments pursuant to Section 3, and in no event shall the Company be required to make
payments or provide benefits to Employee under both Section 3 and Section 4.

          (b) Change of Control of the Company Defined. For purposes of this Section 4, the
term “Change of Control of the Company” shall mean the occurrence of any of the following:

               (i) an acquisition (other than directly from the Company) of any voting securities of the
Company (the “Voting Securities”) by any “Person” (as the term person is used for

9

 

purposes of
Section 13(d) or 14(d) of the Exchange Act), immediately after which such Person has “Beneficial
Ownership” (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of fifty percent
(50%) or more of the then outstanding common stock of the Company (“Shares”) or the combined voting
power of the Company’s then outstanding Voting Securities; provided, however, in determining
whether a Change of Control has occurred pursuant to this subsection (a), Shares or Voting
Securities which are acquired in a “Non-Control Acquisition” (as hereinafter defined) shall not
constitute an acquisition which would cause a Change of Control. A “Non-Control Acquisition” shall
mean an acquisition by (a) an employee benefit plan (or a trust forming a part thereof) maintained
by (1) the Company or (2) any corporation or other Person of which a majority of its voting power
or its voting equity securities or equity interest is owned, directly or indirectly, by the Company
(for purposes of this definition, a “Related Entity”), (b) the Company or any Related Entity, or
(c) any Person in connection with a “Non-Control Transaction” (as hereinafter defined);

               (ii) the individuals who, as of the Effective Time, are members of the Board (the “Incumbent
Board”), cease for any reason to constitute at least a majority of the members of the Board or,
following a Merger Event which results in a Parent Corporation, the board of directors of the
ultimate Parent Corporation (as defined in paragraph (iii)(1)(A) below); provided, however, that if
the election, or nomination for election by the Company’s common stockholders, of any new director
was approved by a vote of at least two-thirds of the Incumbent Board, such new director shall, for
purposes of this Agreement, be considered as a member of the Incumbent Board; provided further,
however, that no individual shall be considered a member of the Incumbent Board if such individual
initially assumed office as a result of an actual or threatened solicitation of proxies or consents
by or on behalf of a Person other than the Board (a “Proxy Contest”) including by reason of any
agreement intended to avoid or settle a Proxy Contest; or

               (iii) the consummation of:

                    (1) a merger, consolidation or reorganization with or into the Company or in which securities
of the Company are issued ( a “Merger Event”), unless such Merger Event is a “Non-Control
Transaction.” A “Non-Control Transaction” shall mean a Merger Event where:

                         (A) the stockholders of the Company, immediately before such Merger Event own directly or
indirectly immediately following such Merger Event at least fifty percent (50%) of the combined
voting power of the outstanding voting securities of (x) the corporation resulting from such Merger
Event (the “Surviving Corporation”) if fifty percent (50%) or more of the combined voting power of
the then outstanding voting securities of the Surviving Corporation is not Beneficially Owned,
directly or indirectly by another Person (a “Parent
Corporation”), or (y) if there are one or more Parent Corporations, the ultimate Parent
Corporation; and,

                         (B) the individuals who were members of the Incumbent Board immediately prior to the execution
of the agreement providing for such Merger Event constitute at least a majority of the members of
the board of directors of (x) the Surviving

10

 

Corporation, if there are no Parent Corporation, or (y)
if there are one or more Parent Corporations, the ultimate Parent Corporation; and

                         (C) no Person other than (1) the Company, (2) any Related Entity, (3) any employee benefit
plan (or any trust forming a part thereof) that, immediately prior to such Merger Event was
maintained by the Company or any Related Entity, or (4) any Person who, immediately prior to such
Merger Event had Beneficial Ownership of fifty percent (50%) or more of the then outstanding Voting
Securities or Shares, has Beneficial Ownership of fifty percent (50%) or more of the combined
voting power of the outstanding voting securities or common stock of (x) the Surviving Corporation
if there is no Parent Corporation, or (y) if there are one or more Parent Corporations, the
ultimate Parent Corporation.

                    (2) a complete liquidation or dissolution of the Company; or

                    (3) the sale or other disposition of all or substantially all of the assets of the Company to
any Person (other than a transfer to a Related Entity or under conditions that would constitute a
Non-Control Transaction with the disposition of assets being regarded as a Merger Event for this
purpose or the distribution to the Company’s stockholders of the stock of a Related Entity or any
other assets).

          Notwithstanding the foregoing, a Change of Control shall not be deemed to occur solely because
any Person (the “Subject Person”) acquired Beneficial Ownership of more than the permitted amount
of the then outstanding Shares or Voting Securities as a result of the acquisition of Shares or
Voting Securities by the Company which, by reducing the number of Shares or Voting Securities then
outstanding, increases the proportional number of shares Beneficially Owned by the Subject Persons,
provided that if a Change of Control would occur (but for the operation of this sentence) as a
result of the acquisition of Shares or Voting Securities by the Company, and after such share
acquisition by the Company, the Subject Person becomes the Beneficial Owner of any additional
Shares or Voting Securities which increases the percentage of the then outstanding Shares or Voting
Securities Beneficially Owned by the Subject Person, then a Change of Control shall occur.

          In addition, a Change of Control shall not be deemed to occur unless the event(s) that causes
such Change of Control also constitutes a “change in control event,” as such term is defined in
Code Section 409A.

          (c) Other Incentives. Upon a Change of Control, any outstanding awards under Executive
Incentive Plan or the Synergy Incentive Savings Plan shall be treated in accordance with such
plans.

     5. Gross-Up Payment.

          (a) Amount.

11

 

               (i) If any payment or benefit provided to Employee by the Company (“Base Payment”) would
subject the Employee to the excise tax (“Excise Tax”) imposed by Section 4999 of the Code (or any
other similar tax that may hereafter be imposed) and such Excise Tax is imposed on account of a
Base Payment made within two years of the Merger and there has been no Change of Control, the
Company shall pay to the employee the “Gross-Up Payment” described in Section 5(a)(iv) below.

               (ii) In the event that a Base Payment would subject the Employee to the Excise Tax as a result
of a Change of Control and the Base Payment is less than 110% of the sum of three (3) times the
“base amount” (as defined in Code Section 280G) minus $1.00 (“Safe Harbor Amount”), then any
amounts payable under this Agreement shall be reduced so that the Base Payment, in the aggregate,
is reduced to the Safe Harbor Amount. The reduction of the amounts payable under this Agreement
shall be made by first reducing the cash payments payable under this Agreement. No reduction shall
occur if the Base Payment is 110% (or more) of the Safe Harbor Amount.

               (iii) In the event that (a) there is a Base Payment which would subject the Employee to the
Excise Tax as a result of a Change of Control, (b) the reduction in Section 5(a)(ii) is not
applicable, and (c) (1) there has been a Change of Control prior to the first anniversary of the
Effective Time of the Merger or (2) the Change of Control occurs on or after the first anniversary
of Effective Time of the Merger and the closing stock price of the Company on the date of the
Change of Control equals or exceeds the Threshold Share Price (as defined below), then the Employee
shall be entitled to receive the payment described in Section 5(a)(iv) below. For this purpose,
the “Threshold Share Price” equals the average closing price of a share of Company common stock
over the first twenty (20) days following the Merger. The Threshold Share Price may be reviewed
annually and adjusted at the discretion of the Compensation Committee.

               (iv) If the Base Payment is subject to the Excise Tax imposed by Section 4999 of the Code and
the requirements of Section 5(a)(i) or 5(a)(iii) are met, the Company shall pay to Employee the
Gross-Up Payment determined as follows: The “Gross-Up Payment” shall be equal to the sum of (a)
the Excise Tax imposed with respect to the Base Payment, plus (b) the Excise Tax imposed with
respect to the Gross-Up Payment, plus (c) all other taxes imposed on Employee with respect to the
Gross-Up Payment, including income taxes and Employee’s share of FICA, FUTA and other payroll
taxes. The Gross-Up Payment shall not include the payment of any tax on the Base Payment other
than the Excise Tax. The Gross-Up Payment is intended to place Employee in the
same economic position Employee would have been in if the Excise Tax did not apply, and shall
be calculated in accordance with such intent.

          (b) Tax Rates and Assumptions. For purposes of determining the amount of the Gross-Up
Payment, Employee 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
Employee’s residence on the date of termination, net of the maximum reduction in Federal income
taxes which could be obtained from deduction of such state and local taxes.

12

 

          (c) Payment and Calculation Procedures. The Gross-Up Payment attributable to a Base
Payment shall be paid to Employee in cash and at such times as such Base Payment is paid or
provided pursuant to this Agreement. Simultaneously with or prior to the Company’s payment of a
Base Payment, the Company shall deliver to Employee a written statement specifying the total amount
of the Base Payment and the Excise Tax and Gross-Up Payment relating to the Base Payment, if any,
together with all supporting calculations and conclusions. If Employee disagrees with the
Company’s determination of the Excise Tax or Gross-Up Payment, Employee shall submit to the
Company, no later than 30 days after receipt of the Company’s written statement, a written notice
advising the Company of the disagreement and setting forth Employee’s calculation of said amounts.
Employee’s failure to submit such notice within such period shall be conclusively deemed to be an
agreement by Employee as to the amount of the Excise Tax and Gross-Up Payment, if any. If the
Company agrees with Employee’s calculations, it shall pay any shortfall in the Gross-Up Payment to
Employee within 20 days after receipt of such a notice from Employee. If the Company does not
agree with Employee’s calculations, it shall provide Employee with a written notice within 20 days
after the receipt of Employee’s calculations advising Employee that the disagreement is to be
referred to an independent accounting firm for resolution. Such disagreement shall be referred to
a nationally recognized independent accounting firm which is not the regular accounting firm of the
Company and which is designated by the Company. The Company shall be required to designate such
accounting firm within 10 days after issuance of the Company’s notice of disagreement. The
accounting firm shall review all information provided to it by the parties and submit a written
report to the parties setting forth its calculation of the Excise Tax and the Gross-Up Payment
within 15 days after submission of the matter to it, and such decision shall be final and binding
on all of the parties. The fees and expenses charged by said accounting firm shall be paid by the
Company. If the amount of the Gross-Up Payment actually paid by the Company was less than the
amount calculated by the accounting firm, the Company shall pay the shortfall to Employee within 5
days after the accounting firm submits its written report. If the amount of the Gross-Up Payment
actually paid by the Company was greater than the amount calculated by the accounting firm,
Employee shall pay the excess to the Company within 5 days after the accounting firm submits its
written report.

          (d) Subsequent Recalculation. In the event the Internal Revenue Service or other
applicable governmental authority imposes an Excise Tax with respect to a Base Payment that is
greater than the amount of the Excise Tax determined pursuant to the immediately preceding
paragraph, the Company shall reimburse Employee for the full amount of such additional Excise Tax
plus any interest and penalties which may be imposed in connection therewith, and pay to Employee
a Gross-up Payment sufficient to make Employee whole and reimburse Employee for any Excise
Tax, income tax and other taxes imposed on the reimbursement of such additional Excise Tax and
interest and penalties, in accordance with the principles set forth above.

          (e) Example. The calculation of the Gross-Up Payment is illustrated by the example
set forth in Schedule 5(e), attached to this Agreement and hereby incorporated by reference. The
amounts set forth in such example are for illustration purposes only and no implication shall be
drawn from such example as to the amounts otherwise payable to Employee by the Company.

13

 

     6. Successor To Company. The Company shall require any successor, whether direct or
indirect, to all or substantially all of the business, properties and assets of the Company whether
by purchase, merger, consolidation or otherwise, prior to or simultaneously with such purchase,
merger, consolidation or other acquisition to execute and to deliver to Employee a written
instrument in form and in substance reasonably satisfactory to Employee pursuant to which any such
successor shall agree to assume and to timely perform or to cause to be timely performed all of the
Company’s covenants, agreements and obligations set forth in this Agreement (a “Successor
Agreement”). The failure of the Company to cause any such successor to execute and deliver a
Successor Agreement to Employee shall constitute a material breach of the provisions of this
Agreement by the Company.

     7. Restrictive Covenants. In consideration of his employment and the other benefits
arising under this Agreement, Employee agrees that during the term of this Agreement, and for a
period of three (3) years following the termination of this Agreement, Employee shall not directly
or indirectly:

          (a) alone or as a partner, joint venturer, officer, director, member, employee, consultant,
agent, independent contractor or stockholder of, or lender to, any company or business, (i) engage
in the business of solid waste collection, disposal or recycling (the “Solid Waste Services
Business”) in any market in which the Company or any of its subsidiaries or affiliates does
business, or any other line of business which is entered into by the Company or any of its
subsidiaries or affiliates during the term of this Agreement, or (ii) compete with the Company or
any of its subsidiaries or affiliates in acquiring or merging with any other business or acquiring
the assets of such other business; or

          (b) for any reason, (i) induce any customer of the Company or any of its subsidiaries or
affiliates to patronize any business directly or indirectly in competition with the Solid Waste
Services Business conducted by the Company or any of its subsidiaries or affiliates in any market
in which the Company or any of its subsidiaries or affiliates does business; (ii) canvass, solicit
or accept from any customer of the Company or any of its subsidiaries or affiliates any such
competitive business; or (iii) request or advise any customer or vendor of the Company or any of
its subsidiaries or affiliates to withdraw, curtail or cancel any such customer’s or vendor’s
business with the Company or any of its subsidiaries or affiliates; or

          (c) for any reason, employ, or knowingly permit any company or business directly or indirectly
controlled by him, to employ, any person who was employed by the Company or any of
its subsidiaries or affiliates at or within the prior six months, or in any manner seek to
induce any such person to leave his or her employment.

          Notwithstanding the foregoing, the beneficial ownership of less than five percent (5%) of the
shares of stock of any corporation having a class of equity securities actively traded on a
national securities exchange or over-the-counter market shall not be deemed, in and of itself, to
violate the prohibitions of this Section.

     8. Confidentiality. Employee agrees that at all times during the term of this
Agreement and after the termination of employment for as long as such information remains
non-public

14

 

information, Employee shall (i) hold in confidence and refrain from disclosing to any
other party all information, whether written or oral, tangible or intangible, of a private, secret,
proprietary or confidential nature, of or concerning the Company or any of its subsidiaries or
affiliates and their business and operations, and all files, letters, memoranda, reports, records,
computer disks or other computer storage medium, data, models or any photographic or other tangible
materials containing such information (“Confidential Information”), including without limitation,
any sales, promotional or marketing plans, programs, techniques, practices or strategies, any
expansion plans (including existing and entry into new geographic and/or product markets), and any
customer lists, (ii) use the Confidential Information solely in connection with his employment with
the Company or any of its subsidiaries or affiliates and for no other purpose, (iii) take all
precautions necessary to ensure that the Confidential Information shall not be, or be permitted to
be, shown, copied or disclosed to third parties, without the prior written consent of the Company
or any of its subsidiaries or affiliates, and (iv) observe all security policies implemented by the
Company or any of its subsidiaries or affiliates from time to time with respect to the Confidential
Information. In the event that Employee is ordered to disclose any Confidential Information,
whether in a legal or regulatory proceeding or otherwise, Employee shall provide the Company or any
of its subsidiaries or affiliates with prompt notice of such request or order so that the Company
or any of its subsidiaries or affiliates may seek to prevent disclosure. In addition to the
foregoing Employee shall not at any time libel, defame, ridicule or otherwise disparage the
Company.

     9. Specific Performance; Injunction. The parties agree and acknowledge that the
restrictions contained in Sections 7 and 8 are reasonable in scope and duration and are necessary
to protect the Company or any of its subsidiaries or affiliates. If any provision of Section 7 or
8 as applied to any party or to any circumstance is adjudged by a court to be invalid or
unenforceable, the same shall in no way affect any other circumstance or the validity or
enforceability of any other provision of this Agreement. If any such provision, or any part
thereof, is held to be unenforceable because of the duration of such provision or the area covered
thereby, the parties agree that the court making such determination shall have the power to reduce
the duration and/or area of such provision, and/or to delete specific words or phrases, and in its
reduced form, such provision shall then be enforceable and shall be enforced. Employee agrees and
acknowledges that the breach of Section 7 or 8 will cause irreparable injury to the Company or any
of its subsidiaries or affiliates and upon breach of any provision of such Sections, the Company or
any of its subsidiaries or affiliates shall be entitled to injunctive relief, specific performance
or other equitable relief, without being required to post a bond; provided, however, that, this
shall in no way limit any other remedies which the
Company or any of its subsidiaries or affiliates may have (including, without limitation, the
right to seek monetary damages).

     10. Nondisparagement.

          (a) The Employee shall not, at any time during his employment with the Company or thereafter,
make any public or private statement to the news media, to any Company competitor or client, or to
any other individual or entity, if such statement would disparage any of the Company, any of their
respective businesses or any director or officer of any of them or such businesses or would have a
deleterious effect upon the interests of any of such businesses or the

15

 

stockholders or other owners
of any of them; provided, however, that the Employee shall not be in breach of this
restriction if such statements consist solely of (i) private statements made to any officers,
directors or employees of any of the Company by the Employee in the course of carrying out his
duties pursuant to this Agreement or, to the extent applicable, his duties as a director or
officer, or (ii) private statements made to persons other than clients or competitors of any of the
Company (or their representatives) or members of the press or the financial community that do not
have a material adverse effect upon any of the Company; and provided that nothing contained in this
paragraph or in any other provision of this Agreement shall preclude the Employee from making any
statement in good faith that is required by law, regulation or order of any court or regulatory
commission, department or agency.

          (b) The Company shall not, at any time during the Employee’s employment with the Company or
thereafter, authorize any person to make, nor shall the Company condone the making of, any
statement, publicly or privately, by its officers which would disparage the Employee;
provided, however, that the Company shall not be in breach of this restriction if
such statements consist solely of (i) private statements made to any officers, directors or
employees of the Company or (ii) private statements made to persons other than clients or
competitors of any of the Company (or their representatives) or members of the press or the
financial community that do not have a material adverse effect upon the Employee; and
provided, further, that nothing contained in this paragraph or in any other
provision of this Agreement shall preclude any officer, director, employee, agent or other
representative of any of the Company from making any statement in good faith which is required by
any law, regulation or order of any court or regulatory commission, department or agency.

     11. Future Cooperation. The Employee agrees to make himself reasonably available to
the Company and its affiliates in connection with any claims, disputes, investigations, regulatory
examinations or actions, lawsuits or administrative proceedings relating to matters in which the
Employee was involved during the period in which he was Chief Executive Officer of the Company, and
to provide information to the Company and otherwise cooperate with the Company and its affiliates
in the investigation, defense or prosecution of such actions. Employee shall be entitled to
reimbursement of reasonable out of pocket costs for travel and legal costs associated therewith,
approved in advance by the Company.

     12. Payments Contingent on Employee’s Release of Company. All of the payments and
benefits to which the Employee would otherwise be entitled under Sections 3 and 4, except with
respect to payments of accrued and unpaid Base Salary and vacation pay shall be contingent on the
Employee’s delivery to the Company of a signed and enforceable release of all claims against the
Company, other than with respect to employee pension, health or medical benefit plans, rights to
indemnification under the director and officer liability insurance policy, or under the bylaws or
certificate of incorporation of the Company, within thirty (30) days of termination.

     13. Notices. All notices, requests, demands, claims and other communications
hereunder shall be in writing and shall be deemed given if delivered by hand delivery, by certified
or registered mail (first class postage pre-paid), guaranteed overnight delivery or facsimile
transmission if such

16

 

transmission is confirmed by delivery by certified or registered mail (first
class postage pre-paid) or guaranteed overnight delivery to, the following addresses and telecopy
numbers (or to such other addresses or telecopy numbers which such party shall designate in writing
to the other parties): (a) if to the Company, at its principal executive offices, addressed to the
President, with a copy to the General Counsel; and (b) if to Employee, at the address listed on the
signature page hereto.

     14. Amendment. This Agreement may not be modified, amended, or supplemented, except
by written instrument executed by all parties. The rights and remedies of the parties under this
Agreement are in addition to all other rights and remedies, at law or equity, that they may have
against each other.

     15. Assignment; Third Party Beneficiary. This Agreement, and Employee’s rights and
obligations hereunder, may not be assigned or delegated by him. The Company may assign its rights,
and delegate its obligations, hereunder to any affiliate of the Company, or any successor to the
Company or its Solid Waste Services Business, specifically including the restrictive covenants set
forth in Section 7 hereof. The rights and obligations of the Company under this Agreement shall
inure to the benefit of and be binding upon its respective successors and assigns.

     16. Severability; Survival. In the event that any provision of this Agreement is
found to be void and unenforceable by a court of competent jurisdiction, then such unenforceable
provision shall be deemed modified so as to be enforceable (or if not subject to modification then
eliminated herefrom) to the extent necessary to permit the remaining provisions to be enforced in
accordance with the parties intention. The provisions of Sections 7, 8, 10 and 11 will survive the
termination for any reason of Employee’s relationship with the Company.

     17. Indemnification. The Company agrees to indemnify Employee during the term and
after termination of this Agreement in accordance with the provisions of the Company’s certificate
of incorporation and bylaws and the Delaware General Corporation Law.

     18. Counterparts. This Agreement may be signed in any number of counterparts, each of
which shall be an original but all of which together shall constitute one and the same instrument.

     19. Governing Law. This Agreement shall be construed in accordance with and governed
for all purposes by the laws of the State of Arizona applicable to contracts executed and to be
wholly performed within such State.

     20. Entire Agreement. This Agreement contains the entire understanding of the parties
in respect of its subject matter and supersedes all prior agreements and understandings (oral or
written) between or among the parties with respect to such subject matter. Upon the execution of
this Agreement the provisions of the Existing Employment Agreement shall be superseded and shall be
of no further force. Employee waives any right to terminate for Good Reason pursuant to Section
3(c) except Section 3(c)(vi) as of the date of this Agreement.

     21. Headings. The headings of Paragraphs and Sections are for convenience of
reference and are not part of this Agreement and shall not affect the interpretation of any of its
terms.

17

 

     22. Construction. This Agreement shall be construed as a whole according to its fair
meaning and not strictly for or against any party. The parties acknowledge that each of them has
reviewed this Agreement and has had the opportunity to have it reviewed by their respective
attorneys and that any rule of construction to the effect that ambiguities are to be resolved
against the drafting party shall not apply in the interpretation of this Agreement. Words of one
gender shall be interpreted to mean words of another gender when necessary to construe this
Agreement, and in like manner words in singular may be interpreted to be in the plural, and vice
versa.

     23. Attorneys’ Fees. If at any time following a Change of Control of the Company,
there should arise any dispute as to the validity, interpretation or application of any term or
condition of this Agreement, the Company agrees, upon written demand by Employee (and Employee
shall be entitled upon application to any court of competent jurisdiction, to the entry of a
mandatory injunction, without the necessity of posting any bond with respect thereto, compelling
the Company) to promptly provide sums sufficient to pay on a current basis (either directly or by
reimbursing Employee) Employee’s costs and reasonable attorneys’ fees (including expenses of
investigation and disbursements for the fees and expenses of experts, etc.) incurred by Employee in
connection with any such dispute, litigation or arbitration up to $50,000 (and additional
reasonable amounts above $50,000, in the sole discretion of the Compensation Committee of the Board
of Directors), and provided further that Employee shall repay any such amounts paid or advanced if
Employee is not the prevailing party with respect to at least one material claim or issue in such
dispute, litigation or arbitration. If at any time when there has not previously been a Change of
Control of the Company, there should arise any dispute, litigation, or arbitration as to the
validity, interpretation or application of any term or condition of the Agreement, the prevailing
party in such dispute, litigation or arbitration shall be entitled to recover from the
non-prevailing party its costs and reasonable attorneys’ fees (including expenses of investigation
and disbursements for the fees and expenses of experts, etc.) incurred in such dispute, litigation
or arbitration. The provisions of this Section 23, without implication as to any other section
hereof, shall survive the expiration or termination of this Agreement and Employee’s employment
hereunder.

     24. Withholding. All payments made to Employee shall be made net of any applicable
withholding for income taxes, Excise Tax and Employee’s share of FICA, FUTA or other taxes. The
Company shall withhold such amounts from such payments to the extent required by applicable law and
remit such amounts to the applicable governmental authorities in accordance with applicable law.

     25. Retirement Eligibility. Upon Employee’s retirement, in lieu of payments under
Sections 3 and 4, the Company shall pay to Employee all of Employee’s accrued but unpaid Base
Salary through the date of retirement. In addition, for all stock option or restricted stock
awards (“Equity Awards”) and all monetary awards (including Annual Awards and Long Term Awards
pursuant to the Executive Incentive Plan and any retirement contributions to the deferred
compensation program) (“Monetary Awards”), in each case granted to Employee prior to July 26, 2006
(“Prior Awards”), such Employee shall be eligible to retire for purposes of the Prior Awards, and
such Prior Awards shall fully vest in the event of such retirement, upon attaining either (a) the
age of fifty-five (55) and having completed six (6) years of service with the Company or (b) the
age of

18

 

sixty-five (65) without regard to years of service with the Company (the “Original
Retirement Policy”). For all Equity Awards and/or Monetary Awards granted to Employee following
July 26, 2006 (“Prospective Awards”), the Original Retirement Policy shall apply, and such
Prospective Awards shall fully vest in the event of such retirement, provided, and only to the
extent that, Employee shall provide the Company with not less than twelve (12) months prior written
notice of Employee’s intent to retire. Failure by Employee to provide such written notice shall
cause the Revised Retirement Policy (as hereinafter defined) to apply with respect to the vesting
of Prospective Awards, but such failure shall have no effect whatsoever on the Prior Awards, all of
which shall continue to be subject to the Original Retirement Policy. For purposes of this
Agreement, (i) “Revised Retirement Policy” shall mean Employee has attained the age of (x) sixty
(60) and has completed fifteen (15) years of continuous service with the Company or (y) sixty-five
(65) with five (5) years of continuous service with the Company, and (ii) all Annual Awards and all
Long Term Awards includable within the Monetary Awards to be fully vested as provided above shall
include all such Awards which have been granted to Employee, but which, as of the date of his
retirement, have not been determined to have been earned pursuant to the Plan and in such instance
Employee shall be paid an amount with respect to each such open Award equal to (x) for award
periods beginning on or before January 1, 2009, the full target amount that the Compensation
Committee of the Board of Directors was authorized to cause to be paid to Employee pursuant to the
Executive Incentive Plan, within thirty (30) days following the date of Employee’s retirement, and
(y) for award periods beginning after January 1, 2009, the prorated portion of the Annual Awards
and Long Term Awards payment that the Compensation Committee of the Board of Directors determines
would have been paid to Employee pursuant to the Executive Incentive Plan had Employee’s employment
continued to the end of the Performance Period multiplied by a fraction, the numerator of which is
the number of completed months of employment during such Performance Period and the denominator of
which is the total number of months in the Performance Period, within sixty (60) days after the end
of the Company’s Fiscal Year in which the Performance Period ends.

     26. Code Section 409A.

          (a) General. It is the intention of both the Company and Employee that the benefits
and rights to which Employee could be entitled pursuant to this Agreement comply with Code Section
409A, to the extent that the requirements of Code Section 409A are applicable thereto, and the
provisions of this Agreement shall be construed in a manner consistent with that intention. If
Employee or the Company believes, at any time, that any such benefit or right that is subject to
Code Section 409A does not so comply, it shall promptly advise the other and shall negotiate
reasonably and in good faith to amend the terms of such benefits and rights such that they comply
with Code Section 409A (with the most limited possible economic effect on Employee and on the
Company).

          (b) Distributions on Account of Separation from Service. If and to the extent
required to comply with Code Section 409A, any payment or benefit required to be paid under this
Agreement on account of termination of Employee’s employment shall be made upon Employee incurring
a “separation of service” within the meaning of Code Section 409A.

19

 

          (c) Timing of Severance Payments. Notwithstanding anything in this Agreement to the
contrary, if Employee is deemed to be a “specified employee” for purposes of Code Section 409A, no
Severance Payment or other payments pursuant to, or contemplated by, this Agreement shall be made
to Employee by the Company before the date that is six months after the Employee’s “separation from
service” (or, if earlier, the date of Employee’s death) if and to the extent that such payment or
benefit constitutes deferred compensation (or may be nonqualified deferred compensation) under Code
Section 409A. Any payment or benefit delayed by reason of the prior sentence shall be paid out or
provided in a single lump sum at the end of such required delay period in order to catch up to the
original payment schedule.

          (d) No Acceleration of Payments. Neither the Company nor Employee, individually or in
combination, may accelerate any payment or benefit that is subject to Code Section 409A, except in
compliance with Code Section 409A and the provisions of this Agreement, and no amount that is
subject to Code Section 409A shall be paid prior to the earliest date on which it may be paid
without violating Code Section 409A.

          (e) Treatment of Each Installment as a Separate Payment. For purposes of applying the
provisions of Code Section 409A to this Agreement, each separately identified amount to which
Employee is entitled under this Agreement shall be treated as a separate payment. In addition, to
the extent permissible under Code Section 409A, any series of installment payments under this
Agreement shall be treated as a right to a series of separate payments.

          (f) Reimbursements. Notwithstanding anything in this Agreement to the contrary, any
payment, to the extent such payment constitutes deferral of compensation under Code Section 409A,
to reimburse the Employee in an amount equal to all or a designated portion of the Federal, state,
local, or foreign taxes imposed upon Employee as a result of compensation paid or made available to
Employee by the Company, including the amount of additional taxes imposed upon Employee due to the
Company’s payment of the initial taxes on such compensation, or for other reimbursements, shall be
made no later than the end of Employee’s taxable year next following Employee’s taxable year in
which Employee remits the related taxes or incurs such expense.

          (g) Continued Health Benefits. In the event that Employee receives continued health
benefits pursuant to Section 3 or 4 of this Agreement, such expense or reimbursement shall meet the
following requirements: (i) the amount of expenses eligible for reimbursement provided to Employee
during any calendar year will not affect the amount of expenses eligible for reimbursement or
in-kind benefits provided to Employee in any other calendar year, (ii) the reimbursements for
expenses for which Employee is entitled to be reimbursed shall be made on or before the last day of
the calendar year following the calendar year in which the applicable expense is incurred, and
(iii) the right to payment or reimbursement on in-kind benefits hereunder may not be liquidated or
exchanged for any other benefit.

     27. Beneficiary. If the Employee dies before receiving any payments due to him under
Sections 3 or 4, the remaining payments will be paid to his beneficiary.

20

 

     28. Arbitration. Except with respect to the remedies set forth in Section 9 hereof,
if in the event of any controversy or claim between the Company or any of its affiliates and the
Employee arising out of or relating to this Agreement, either party delivers to the other party a
written demand for arbitration of a controversy or claim then such claim or controversy shall be
submitted to binding arbitration. The binding arbitration shall be administered by the American
Arbitration Association under its Commercial Arbitration Rules. The arbitration shall take place
in Maricopa County, Arizona. Each of the Company and the Employee shall appoint one person to act
as an arbitrator, and a third arbitrator shall be chosen by the first two arbitrators (such three
arbitrators, the “Panel”). The Panel shall have no authority to award punitive damages against the
Company or the Employee. The arbitrator shall have no authority to add to, alter, amend or refuse
to enforce any portion of the disputed agreements. The Company and the Employee each waive any
right to a jury trial or to petition for stay in any action or proceeding of any kind arising out
of or relating to this Agreement.

Schedule 5(e)

Gross-Up Payment Example

     Assume that the Company makes a Base Payment to Employee of $900,000, and that $600,000 is
subject to an Excise Tax of 20%. Also assume that the maximum combined effective federal, state
and local tax rate, including Employee’s share of payroll taxes but not including the Excise Tax
rate, is 45%. Under these circumstances, the Gross-Up Payment would be $342,857.14.

     The Gross-Up Payment in this example is equal to the amount of the Base Payment subject to
the Excise Tax ($600,000), multiplied by the Excise Tax rate, expressed as a decimal (.20), and
divided by the remainder of 1 minus the Excise Tax rate, expressed as a decimal, and minus the
effective rate of tax of Employee exclusive of the Excise Tax, expressed as a decimal (1-.20-.45).
Hence, the Gross-Up Payment is $600,000 x .20 / (1-.20-.45) = $342,857.14.

     The Gross-Up Payment of $342,857.14 represents the sum of the amounts referred to in clauses
(a), (b) and (c) of Section 5(a)(iv) of this Agreement, as set forth below.

	 	 	 	 	 
	clause (a):
	 	 	 	 
	Excise Tax on Base Payment (600,000 x .20)
	 	$	120,000.00	 
	clause (b):
	 	 	 	 
	Excise Tax on Gross-Up Payment (342,857.14 x .20)
	 	 	68,571.43	 
	clause (c):
	 	 	 	 
	Other taxes on Gross-Up Payment (342,857.14 x .45)
	 	 	154,285.71	 
	 
	 	 	 
	Total taxes subject to gross-up
	 	 	342,857.14
