 Exhibit 10.1 
 PERFORMANCE SHARE UNIT AWARD AGREEMENT 
 FOR RETURN ON INVESTED CAPITAL

 This Performance Share Unit Award Agreement (“Agreement”) is entered into effective as of March 8, 2013,
(the “Grant Date”), by and between Waste Management, Inc., a Delaware corporation (together with its Subsidiaries and Affiliates, the “Company”), and you, (the “Employee”), pursuant to the Waste Management, Inc. 2009
Stock Incentive Plan (the “Plan”). Employee and the Company agree to execute such further instruments and to take such further action as may reasonably be necessary to carry out the intent of this Agreement. The terms and conditions of
this Agreement as offered herein must be accepted by Employee prior to April 22, 2013. Failure to timely accept the terms by such time will result in the immediate and irrevocable cancellation of the Award offered. 

1. Grant. In accordance with, and subject to, the terms of the Plan, the Company hereby grants to Employee a Performance Share
Unit Award (the “Award”) subject to the terms and conditions set forth herein. Performance Share Units are notational units of measurement denominated in shares of common stock of Waste Management, Inc., $.01 par value, (“Common
Stock”), subject to the conditions and restrictions on transferability set forth below and in the Plan. 
 2. Return on
Invested Capital Performance Requirement. 
 (a) The “Performance Period” for this Award shall be
the 36-month period commencing on January 1, 2013 and ending on December 31, 2015. The Award shall be subject to performance vesting requirements based upon the achievement of the Incentive Formula established under the Plan, adjusted so
that the Award that is paid to the Employee hereunder does not exceed the amount computed under the performance goal specified below, subject to certification of the degree of achievement of such performance goal by the Committee. 

(b) The measurement tool for determining level of achievement shall be Average Return on Invested Capital for the
36-month period beginning January 1, 2013 and ending December 31, 2015. Calculation of this measurement tool will be performed by the Committee, subject to all authority granted under the terms of the Plan, including adjustments that may
be made by the Committee to take into account any factors that the Committee has determined are not properly reflected in such reported figures. Such adjustments may include, but are not limited to, income tax adjustments, strike costs, remedial
reserve adjustments, acquisitions and other unusual items. 
 (c) Notwithstanding any other term of this
Agreement to the contrary, in order to be eligible to vest in any portion of the Award, Employee must also have entered into an agreement containing restrictive covenants concerning limitations on Employee’s behavior following termination of
employment that is satisfactory to the Company and its affiliates.

 3. Determining Number of Performance Share Units Earned. 

(a) The “Target Award” for Employee under this Agreement is the target number of Performance Share Units
announced on March 9, 2012. The actual number of Performance Share Units earned by Employee will be determined as described below, based upon the actual achievement of the performance goal for the Performance Period. “Threshold
Performance” is the minimum level of performance that must be achieved to qualify for any Award; “Target Performance” is the expected achievement in Average Return on Invested Capital; and “Maximum Performance” is the
maximum level of performance that could be achieved that would result in an increase in the number of Performance Share Units earned under this Award. The target levels of achievement for the performance goal will be announced by no later than
March 15, 2013, following calculation of year-end financial reporting for 2012. Subject to adjustment pursuant to Subsection 3(b), 3(c) and 3(d), each such percentage correlates to a number of Performance Share Units that may be earned under
this Award, as follows: 
  

			
	 Level Achieved During Performance Period
	  	 Resulting Payout Percentage Earned

	Threshold Performance	  	60% of Target Award
	Target Performance	  	100% of Target Award
	Maximum Performance	  	200% of Target Award

 (b) In the event that the Company’s actual performance does not meet the Threshold
Performance, no Performance Share Units shall be earned under this Award. 
 (c) If the Company’s actual
performance for the Performance Period is between Threshold Performance and Target Performance, the number of Performance Share Units earned shall be straight-line interpolated between Threshold Performance and Target Performance payout percentages.

 (d) If the Company’s actual performance for the Performance Period is between Target Performance and
Maximum Performance, the number of Performance Share Units earned shall be straight-line interpolated between Target Performance and Maximum Performance payout percentages. 
 4. Timing and Form of Payout. Except as hereinafter provided, after the end of the Performance Period, Employee shall be entitled to receive his total number of Performance Shares Units determined
under Section 3 and Dividend Equivalents under Section 11. Unless timely deferred by Employee in accordance with Section 12, upon vesting, each Performance Share Unit will be settled by payment of one share of Common Stock, free of
any restrictions. Payment of such shares of Common Stock shall be made as soon as administratively feasible after the Committee certifies the actual performance of the Company during the Performance Period. The Company shall not be required to issue
any fractional shares of Common Stock.

 5. Termination of Employment Due to Death or Disability. Upon Termination of
Employment from the Company by reason of Employee’s death or disability (as determined by the Committee and within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”)), or
upon Employee’s disability prior to a Termination of Employment (as determined by the Committee and within the meaning of Section 409A of the Internal Revenue Code), Employee (or in the case of Employee’s death, Employee’s
beneficiary) shall be entitled to receive the Performance Share Units and related Dividend Equivalents that Employee would have been entitled to under Section 3 if Employee had remained employed until the last day of the Performance Period.
Unless further deferred pursuant to Employee’s deferral election, the delivery of shares of Common Stock in satisfaction of such Performance Share Units shall be made as soon as administratively feasible after the end of the Performance Period.

 6. Involuntary Termination of Employment Without Cause by the Company or Retirement by Employee. Upon either an
involuntary Termination of Employment from the Company without Cause by the Company or a qualifying Retirement by Employee, Employee shall be entitled to receive the Performance Share Units and related Dividend Equivalents that Employee would have
been entitled to under Section 3 if Employee had remained employed until the last day of the Performance Period, multiplied by the fraction which has as its numerator the total number of days that Employee was employed by the Company during the
Performance Period and has as its denominator 1,095 (being the number of calendar days in the Performance Period). Unless further deferred pursuant to Employee’s deferral election, the delivery of shares of Common Stock in satisfaction of such
Performance Share Units shall be made as soon as administratively feasible after the end of the Performance Period. 
 7.
Termination of Employment for Any Other Reason. Except as provided in Sections 5 and 6, Employee must be an employee of the Company continuously from the date of this Award until the last day of the Performance Period to be entitled to
receive any shares of Common Stock with respect to any Performance Share Units that Employee may have earned hereunder. 
 8.
Repayment of Benefits Arising from Misconduct. 
 (a) Notwithstanding any provision of this Agreement to
the contrary, if it is determined by the Committee that Employee either engaged in or benefited from Misconduct, as defined below, then, to the extent permitted by law, Employee will refund to the Company any amounts, plus interest, received by
Employee under this Agreement. For purposes of this Section, “Misconduct” means (i) any act or failure to act by any employee of the Company that (ii) caused or was intended to cause a violation of the Company’s policies,
generally accepted accounting principles or any applicable laws in effect at the time of the act(s) or failure(s) to act in question and that (iii) materially increased the value of the payment or award received by Employee under this
Agreement. Determination as to the existence of Misconduct shall be made by an independent third party (either a law firm or an accounting firm) appointed by the Committee. 

  
 -3-

 (b) Following finding of Misconduct by such a third party, if Employee has
been accused engaging in Misconduct may dispute the occurrence of Misconduct pursuant to binding arbitration. Individuals determined to have benefited from, but not engaged in, Misconduct will have no right to challenge the finding of Misconduct
through arbitration. The Company and Employee hereby agree that any dispute arising out of or relating to a finding that Employee engaged in Misconduct shall be settled exclusively by final and binding arbitration, as governed by the Federal
Arbitration Act (9 U.S.C. 1 et seq.). The arbitration proceeding, including the rendering of an award, shall be administered by JAMS pursuant to its Employment Arbitration Rules and Procedures, which may be found on the JAMS web site
www.jamsadr.com. All expenses associated with the arbitration shall be borne by Company. Such arbitration expenses will not include attorney fees incurred by the respective parties. The award of the arbitrator shall be final and binding upon the
parties. Judgment on any arbitration award may be entered in any court having jurisdiction. 
 (c) The Company
must initiate any attempt at recovery pursuant to this Section within the earlier to occur of (i) one year after discovery of alleged Misconduct or (ii) the second anniversary of Employee’s termination of employment. 

(d) The provisions of this Section 8, without implication as to any other section hereof, shall survive the
expiration or termination of this Agreement and of Employee’s employment. 
 9. Acceleration upon Change in Control.

 (a) Notwithstanding anything to the contrary, if there is a Change in Control of Waste Management, Inc. prior
to the end of the Performance Period, Employee will be entitled to immediately receive both (i) and (ii), as follows: 
 (i) the Performance Share Units that Employee would have otherwise received based upon achievement of Average Return on Invested Capital after reducing the Performance Period so that it ends on the last
day of the quarter preceding the Change in Control (the “Early Measurement Date”) and making adjustments to Target Performance so as to be equal to the performance budgeted for that period and appropriate adjustments to Threshold
Performance and Maximum Performance so that they bear the same ratio to the Threshold Performance and Maximum Performance amounts above as the revised Target Performance amount bear to the Target Performance amount above, converted into a cash
payment equivalent to the number of Performance Share Units earned under this Section 9 multiplied by the closing price of the Common Stock on the Early Measurement Date; and 

  
 -4-

 (ii) as a substitute award for the lost opportunity to earn Performance
Share Units for the entire length of the original Performance Period: 
 (A) if the successor entity was a
publicly traded company as of the Early Measurement Date, an award of restricted stock units in the successor entity equal to the number of shares of common stock of the successor entity that could have been purchased on the Early Measurement Date
with an amount of cash equal to the quotient obtained from the following equation: 
  

	
	TAP x (1095 – EMD) x CP
	1095

 TAP = the number of Performance Share Units that could be earned for achievement of the original Target
Performance specified in Section 3(a) 
 EMD = the number of days occurring from the Grant Date to the Early Measurement
Date 
 CP = the closing price of a share of Common Stock of Waste Management, Inc. on the Early Measurement Date 

Any stock units in the successor entity awarded under this Section 9(a)(ii)(A) will vest completely on or before December 31,
2015, provided that Employee remain continuously employed with the successor entity until such date. The foregoing notwithstanding, if there is an involuntary Termination of Employee for reason other than Cause during the Window Period, Employee
will become immediately vested in full in the stock units in the successor entity awarded pursuant to this Section 9(a)(ii)(A). 
 (B) if the successor entity was not a publicly traded company as of the Early Measurement Date, a cash payment equal to the quotient obtained from the following equation: 

 

	
	TAP x (1095 – EMD) x CP
	1095

 TAP = the number of Performance Share Units that could be earned for achievement of the original Target
Performance specified in Section 3(a) 
 EMD = the number of days occurring from the Grant Date to the Early Measurement
Date 
 CP = the closing price of a share of Common Stock of Waste Management, Inc. on the Early Measurement Date 

Any cash payment calculated under this Section 9(a)(ii)(B) will be paid to Employee on December 31, 2015, provided that
Employee remain continuously employed with the successor entity until such date. The foregoing notwithstanding, if there is an involuntary Termination of Employee for reason other than Cause during the Window Period, Employee will be paid by the
successor entity the amount determined pursuant to this Section 9(a)(ii)(B). 

  
 -5-

 (b) Employee further agrees that, in consideration for the this Award, the
equations detailed above in Section 9(a) shall be substituted for the corollary provisions in each prior award of performance share units previously granted to Employee by the Company. 

10. Forfeiture of Award. Upon Termination of Employment from the Company for any reason other than death, retirement, disability,
involuntary termination by the Company without Cause, or Change in Control, Employee shall immediately forfeit the Award, without the payment of any consideration or further consideration by the Company. Upon forfeiture, neither Employee nor any
successors, heirs, assigns, or legal representatives of Employee shall thereafter have any further rights or interest in the unvested portion of the Award. 
 11. Dividend Equivalents. No Dividend Equivalents will be paid on the Performance Share Units until such time as: (i) the Performance Period has ended; (ii) Employee has vested in the
Award, and; (iii) the number of Performance Share Units earned under this Award has been certified by the Committee based on the actual performance of the Company during the Performance Period. Reasonably promptly after all such events have
occurred, the Company will pay Employee a lump-sum cash amount in payment of Dividend Equivalents based on the number of Performance Share Units earned under the Award multiplied by the per share quarterly dividend payments made to shareholders of
Company’s Common Stock during the Performance Period (without any interest or compounding). Notwithstanding the foregoing, any accumulated and unpaid Dividend Equivalents attributable to Performance Share Units that are cancelled or forfeited
will not be paid and are immediately forfeited upon cancellation of the Performance Share Units. Following the end of the Performance Period, Dividend Equivalents will also be paid on vested Performance Share Units for which a valid deferral
election has been made pursuant to Section 12. With respect to validly deferred and vested Performance Share Units, the Company will pay Dividend Equivalents in cash at such times as dividends are paid on the Company’s outstanding shares
of Common Stock. 
 12. Elective Deferrals. 

(a) The Committee may establish procedures pursuant to which Employee may elect to defer, until a time or times later
than the vesting of a Performance Share Unit, receipt of all or a portion of the shares of Common Stock deliverable in respect of a Performance Share Unit, all on such terms and conditions as the Committee (or its designee) shall determine in its
sole discretion. If any such deferrals are permitted for Employee, then notwithstanding any provision of this Agreement or the Plan to the contrary, an Employee who elects such deferral shall not have any rights as a stockholder with respect to any
such deferred shares of Common Stock unless and until the date the 

  
 -6-

 
deferral expires and certificates representing such shares are required to be delivered to Employee. The foregoing notwithstanding, no deferrals of Dividend Equivalents related to any Performance
Share Units under this Award will be permitted. Moreover, the Committee further retains the authority and discretion to modify and/or terminate existing deferral elections, procedures and distribution options. 

(b) Notwithstanding any provision to the contrary in this Agreement, if deferral of Performance Share Units is permitted,
each provision of this Agreement shall be interpreted to permit the deferral of compensation only as allowed in compliance with the requirements of Section 409A of the Internal Revenue Code and any provision that would conflict with such
requirements shall not be valid or enforceable. Employee acknowledges, without limitation, and consents that application of Section 409A of the Internal Revenue Code to this Agreement may require additional delay of payments otherwise payable
under this Agreement. Employee and the Company further hereby agree to execute such further instruments and take such further action as reasonably may be necessary to comply with Section 409A of the Internal Revenue Code. 

13. Restrictions on Transfer. 
 (a) Absent prior written consent of the Committee, the Award granted hereunder to Employee may not be sold, assigned, transferred, pledged or otherwise encumbered, whether voluntarily or involuntarily, by
operation of law or otherwise; provided, however, that the transfer of any shares of Common Stock with respect to the Performance Share Units earned hereunder shall not be restricted by virtue of this Agreement. 

(b) Consistent with the foregoing, except as contemplated by Section 14, no right or benefit under this Agreement
shall be subject to transfer, anticipation, alienation, sale, assignment, pledge, encumbrance or charge, whether voluntary, involuntary, by operation of law or otherwise, and any attempt to transfer, anticipate, alienate, sell, assign, pledge,
encumber or charge the same shall be void. No right or benefit hereunder shall in any manner be liable for or subject to any debts, contracts, liabilities or torts of the person entitled to such benefits. If Employee or his Beneficiary hereunder
shall attempt to transfer, anticipate, alienate, assign, sell, pledge, encumber or charge any right or benefit hereunder, other than as contemplated by Section 14, or if any creditor shall attempt to subject the same to a writ of garnishment,
attachment, execution sequestration, or any other form of process or involuntary lien or seizure, then such attempt shall have no effect and shall be void. 
 14. Assignment and Transfers. Prior to the end of the Performance Period and the delivery of the Common Stock with respect to any Performance Share Units earned, the Award is not transferable
(either voluntarily or involuntarily), other than pursuant to a domestic relations order. Employee may designate a beneficiary or beneficiaries (the “Beneficiary”) to whom the Performance Share Units will pass upon Employee’s death

  
 -7-

 
and may change such designation from time to time by filing a written designation of beneficiary on such form as may be prescribed by the Company, provided that no such designation shall be
effective until filed with the Company. Following Employee’s death, the Performance Share Units will pass to the designated Beneficiary and such person will be deemed Employee for purposes of any applicable provisions of this Agreement. If no
such designation is made or if the designated Beneficiary does not survive Employee’s death, the Performance Share Units shall pass by will or, if none, then by the laws of descent and distribution. 

15. Withholding Tax. To the extent that the receipt of this Award, vesting, or the delivery of the Common Stock with respect to
any Performance Share Units earned results in a taxable event to Employee for federal or state tax purposes, Employee shall deliver to the Company at the time of such receipt, such amount of money or shares of Common Stock earned or owned by
Employee, at Employee’s election, as the Company may require to meet its obligation under applicable tax laws or regulations, and, if Employee fails to do so, the Company is authorized to withhold from any cash or other form of remuneration
then or thereafter payable to Employee any tax required to be withheld by reasons of such resulting taxation. 
 16. Changes
in Capital Structure. If the outstanding shares of Common Stock or other securities of Waste Management, Inc., or both, shall at any time be changed or exchanged by declaration of a stock dividend, stock split, combination of shares, or
recapitalization, the number of Performance Share Units shall be appropriately and equitably adjusted so as to maintain the proportionate number of shares. 
 17. Compliance with Securities Laws. The Company will not be required to deliver any shares of Common Stock pursuant to this Agreement, if, in the opinion of counsel for the Company, such issuance
would violate the Securities Act of 1933 or any other applicable federal or state securities laws or regulations. Prior to the issuance of any shares pursuant to this Agreement, the Company may require that Employee (or Employee’s legal
representative upon Employee’s death or disability) enter into such written representations, warranties and agreements as the Company may reasonably request in order to comply with applicable securities laws or with this Agreement. 

18. Employee to Have no Rights as a Stockholder. Employee shall have no rights as a stockholder with respect to any shares of
Common Stock subject to this Award prior to the date on which Employee is recorded as the holder of such shares of Common Stock on the records of the Company, including no right to dividends declared on the Common Stock underlying the Award.

 19. Successors and Assigns. 

(a) This Agreement shall bind and inure to the benefit of and be enforceable by Employee, the Company and their
respective permitted successors or assigns (including personal representatives, heirs and legatees), except that Employee may not assign any rights or obligations under this Agreement except to the extent, and in the manner, expressly permitted
herein. 
 (b) The Company shall require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it
if no such succession had taken place.

person any interest in any fund or in any specified asset or assets of the Company (other than the Award and applicable Common Stock following the vesting of such Award); or

21. Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Texas,
without reference to principles of conflict of laws. 
 22. Severability. The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement. 
 23.
No Waiver. The failure of Employee or the Company to insist upon strict compliance with any provision of this Agreement or the failure to assert any right Employee or the Company may have under this Agreement shall not be deemed to be a
waiver of such provision or right or any other provision or right of this Agreement.

 Exhibit 10.2 
 PERFORMANCE SHARE UNIT AWARD AGREEMENT 
 FOR TOTAL SHAREHOLDER RETURN

 This Performance Share Unit Award Agreement (“Agreement”) is entered into effective as of March 8, 2013,
(the “Grant Date”), by and between Waste Management, Inc., a Delaware corporation (together with its Subsidiaries and Affiliates, the “Company”), and you, (the “Employee”), pursuant to the Waste Management, Inc. 2009
Stock Incentive Plan (the “Plan”). Employee and the Company agree to execute such further instruments and to take such further action as may reasonably be necessary to carry out the intent of this Agreement. The terms and conditions of
this Agreement as offered herein must be accepted by Employee prior to April 22, 2013. Failure to timely accept the terms by such time will result in the immediate and irrevocable cancellation of the Award offered. 

1. Grant. In accordance with, and subject to, the terms of the Plan, the Company hereby grants to Employee a Performance Share
Unit Award (the “Award”) subject to the terms and conditions set forth herein. Performance Share Units are notational units of measurement denominated in shares of common stock of Waste Management, Inc., $.01 par value, (“Common
Stock”), subject to the conditions and restrictions on transferability set forth below and in the Plan. The Target Award for Employee under this Agreement is the target number of Performance Share Units based on Total Shareholder Return
announced on March 8, 2013. 
 2. Total Shareholder Return Performance Requirement. 

(a) The “Performance Period” for this Award shall be the 36-month period commencing on January 1, 2013 and
ending on December 31, 2015. 
 (b) The measurement tool for determining level of achievement for this
Award shall be the Relative TSR Percentile Rank of the Company as compared to the other S&P 500 Companies for the Performance Period. 
 3. Determining Number of Performance Share Units Earned. 

(a) Following the calculation of Total Shareholder Return for the Company and each of the other S&P 500 Companies,
the Company and all other S&P Companies will be ranked according to their respective Total Shareholder Return for the Performance Period. The ranking will be in order from minimum to maximum, with the lowest performing entity within the
S&P500 Companies being assigned a rank of one. The Committee shall derive and confirm the number of Performance Share Units earned under this Award based on the Relative TSR Percentile Rank of the Company. Any Award paid to the Employee
hereunder shall not exceed the amount computed under the performance goal specified below, subject to certification of the degree of achievement of such performance goal by the Committee. 

  
 -1-

 (b) For purposes of this Award, “Threshold Performance” is a
Relative TSR Percentile Rank of the Company greater than 25.00% (i.e. above the bottom of the third quartile of the performance group). “Target Performance” is a Relative TSR Percentile Rank of the Company equal to 50.00% (i.e. at median
of the comparison group). “Second Quartile Performance” is a Relative TSR Percentile Rank of the Company equal to 75.00% (i.e. equal to the top of the second quartile of the performance group). And, “Maximum Performance” is a
Relative TSR Percentile Rank of the Company equal to 100% (i.e. the highest performing entity in the comparison group). Subject to adjustment pursuant to Subsection 3(c), 3(d), 3(e) and 3(f), each such percentage correlates to a number of
Performance Share Units that may be earned under this Award, as follows: 
  

			
	 Relative Total Shareholder Return
	  	 Resulting Payout Percentage Earned

	Threshold Performance	  	50% of Target Award
	Target Performance	  	100% of Target Award
	Second Quartile Performance	  	150% of Target Award
	Maximum Performance	  	200% of Target Award

 (c) If the Relative TSR Percentile Rank of the Company for the Performance Period does
not meet or exceed Threshold Performance, no Performance Share Units shall be earned under this Award. 
 (d) If
the Relative TSR Percentile Rank of the Company for the Performance Period is between Threshold Performance and Target Performance, the number of Performance Share Units earned shall be straight-line interpolated between Threshold Performance and
Target Performance payout percentages. 
 (e) If the Relative TSR Percentile Rank of the Company for the
Performance Period is between Target Performance and Second Quartile Performance, the number of Performance Share Units earned shall be straight-line interpolated between Target Performance and Second Quartile Performance payout percentages.

 (f) If the Relative TSR Percentile Rank of the Company for the Performance Period is between Second Quartile
Performance and Maximum Performance, the number of Performance Share Units earned shall be straight-line interpolated between Second Quartile Performance and Maximum Performance payout percentages. 

4. Timing and Form of Payout. Except as hereinafter provided, after the end of the Performance Period, Employee shall be entitled
to receive his total number of Performance Shares Units determined under Section 3 and Dividend Equivalents determined under Section 11. Unless timely deferred by Employee in accordance with Section 12, upon vesting, each Performance
Share Unit will be settled by payment of one share of Common Stock, free of any restrictions. Payment of such shares of Common Stock shall be made as soon as administratively feasible after the Committee certifies the actual performance of the
Company during the Performance Period. The Company shall not be required to issue any fractional shares of Common Stock. 

  
 -2-

 5. Termination of Employment Due to Death or Disability. Upon Termination of
Employment from the Company by reason of Employee’s death or disability (as determined by the Committee and within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”)), or
upon Employee’s disability prior to a Termination of Employment (as determined by the Committee and within the meaning of Section 409A of the Internal Revenue Code), Employee (or in the case of Employee’s death, Employee’s
beneficiary) shall be entitled to receive the Performance Share Units and related Dividend Equivalents that Employee would have been entitled to under if Employee had remained employed throughout the Performance Period. Unless further deferred
pursuant to Employee’s deferral election, the delivery of shares of Common Stock in satisfaction of such Performance Share Units shall be made as soon as administratively feasible after the end of the Performance Period. 

6. Involuntary Termination of Employment Without Cause by the Company or Retirement by Employee. Upon either an involuntary
Termination of Employment from the Company without Cause by the Company or a qualifying Retirement by Employee, Employee shall be entitled to receive the Performance Share Units and related Dividend Equivalents that Employee would have been entitled
to if Employee had remained employed throughout the Performance Period, multiplied by the fraction which has as its numerator the total number of days that Employee was employed by the Company during the Performance Period and has as its denominator
1,095 (being the number of calendar days in the Performance Period). Unless further deferred pursuant to Employee’s deferral election, the delivery of shares of Common Stock in satisfaction of such Performance Share Units shall be made as soon
as administratively feasible after the end of the Performance Period. 
 7. Termination of Employment for Any Other
Reason. Except as provided in Sections 5 and 6, Employee must be an employee of the Company continuously from the date of this Award throughout the entire Performance Period to be entitled to receive any shares of Common Stock with respect to
any Performance Share Units that Employee may earn hereunder. 
 8. Repayment of Benefits Arising from Misconduct.

 (a) Notwithstanding any other term of this Agreement to the contrary, in order to be eligible to vest in any
portion of the Award, Employee must also have entered into an agreement containing restrictive covenants concerning limitations on Employee’s behavior following termination of employment that is satisfactory to the Company and its affiliates.

 (b) Notwithstanding any provision of this Agreement to the contrary, if it is determined by the Committee
that Employee either engaged in or benefited from Misconduct, as defined below, then, to the extent permitted by law, 

  
 -3-

 
Employee will refund to the Company any amounts, plus interest, received by Employee under this Agreement. For purposes of this Section, “Misconduct” means (i) any act or failure
to act by any employee of the Company that (ii) caused or was intended to cause a violation of the Company’s policies, generally accepted accounting principles or any applicable laws in effect at the time of the act(s) or failure(s) to act
in question and that (iii) materially increased the value of the payment or award received by Employee under this Agreement. Determination as to the existence of Misconduct shall be made by an independent third party (either a law firm or an
accounting firm) appointed by the Committee. 
 (c) Following finding of Misconduct by such a third party, if
Employee has been accused engaging in Misconduct may dispute the occurrence of Misconduct pursuant to binding arbitration. Individuals determined to have benefited from, but not engaged in, Misconduct will have no right to challenge the finding of
Misconduct through arbitration. The Company and Employee hereby agree that any dispute arising out of or relating to a finding that Employee engaged in Misconduct shall be settled exclusively by final and binding arbitration, as governed by the
Federal Arbitration Act (9 U.S.C. 1 et seq.). The arbitration proceeding, including the rendering of an award, shall be administered by JAMS pursuant to its Employment Arbitration Rules and Procedures, which may be found on the JAMS web site
www.jamsadr.com. All expenses associated with the arbitration shall be borne by Company. Such arbitration expenses will not include attorney fees incurred by the respective parties. The award of the arbitrator shall be final and binding upon the
parties. Judgment on any arbitration award may be entered in any court having jurisdiction. 
 (d) The Company
must initiate any attempt at recovery pursuant to this Section within the earlier to occur of (i) one year after discovery of alleged Misconduct or (ii) the second anniversary of Employee’s termination of employment. 

(e) The provisions of this Section 8, without implication as to any other section hereof, shall survive the
expiration or termination of this Agreement and of Employee’s employment. 
 9. Acceleration upon Change in Control.

 (a) Notwithstanding anything to the contrary, if there is a Change in Control of Waste Management, Inc. prior
to the end of the Performance Period, Employee will be entitled to immediately receive both (i) and (ii), as follows: 
 (i) the result of the equation with a numerator of: (x) the number of Performance Share Units that Employee would have otherwise received based upon achievement of Relative TSR of the Company after
reducing the Performance Period so that it ends on the last trading day that immediately precedes the Change in Control (the “Early Measurement Date”), multiplied by (y) number of days occurring between the beginning of the
Performance 

  
 -4-

 
Period and the Early Measurement Date, and; a denominator of 1,095, being the total number of days in the original Performance Period. The resulting value shall be converted into a cash payment
equivalent to the number of Performance Share Units earned under such a calculation multiplied by the closing price of the Common Stock on the Early Measurement Date; and 

(ii) as a substitute award for the lost opportunity to earn Performance Share Units for the entire length of the original
Performance Period: 
 (A) if the successor entity was a publicly traded company as of the Early Measurement
Date, an award of restricted stock units in the successor entity equal to the number of shares of common stock of the successor entity that could have been purchased on the Early Measurement Date with an amount of cash equal to the quotient obtained
from the following equation: 
 TAP x (1095 – EMD) x CP 

1095 
 TAP
= the number of Performance Share Units that could be earned for achievement of the original Target Performance specified in Section 3(a) 
 EMD = the number of days occurring from the Grant Date to the Early Measurement Date 
 CP = the closing price of a share of Common Stock of Waste Management, Inc. on the Early Measurement Date 
 Any stock units in the successor entity awarded under this Section 9(a)(ii)(A) will vest completely on or before December 31, 2015, provided that Employee remain continuously employed with the
successor entity until such date. The foregoing notwithstanding, if there is an involuntary Termination of Employee for reason other than Cause during the Window Period, Employee will become immediately vested in full in the stock units in the
successor entity awarded pursuant to this Section 9(a)(ii)(A). 
 (B) if the successor entity was not a
publicly traded company as of the Early Measurement Date, a cash payment equal to quotient obtained from the following equation: 

TAP x (1095 – EMD) x CP 
 1095 
 TAP = the number of Performance Share Units that could be earned for
achievement of the original Target Performance specified in Section 3(a) 
 EMD = the number of days occurring from the
Grant Date to the Early Measurement Date 
 CP = the closing price of a share of Common Stock of Waste Management, Inc. on the
Early Measurement Date 

  
 -5-

 Any cash payment calculated under this Section 9(a)(ii)(B) will be paid to Employee on
December 31, 2015, provided that Employee remain continuously employed with the successor entity until such date. The foregoing notwithstanding, if there is an involuntary Termination of Employee for reason other than Cause during the Window
Period, Employee will be paid by the successor entity the amount determined pursuant to this Section 9(a)(ii)(B). 
 (b) Employee further agrees that, in consideration for the this Award, the equations detailed above in Section 9(a) shall be substituted for the corollary provisions in each prior award of
performance share units previously granted to Employee by the Company. 
 10. Forfeiture of Award. Upon Termination of
Employment from the Company for any reason other than death, retirement, disability, involuntary termination by the Company without Cause, or Change in Control, Employee shall immediately forfeit the Award, without the payment of any consideration
or further consideration by the Company. Upon forfeiture, neither Employee nor any successors, heirs, assigns, or legal representatives of Employee shall thereafter have any further rights or interest in the unvested portion of the Award.

 11. Dividend Equivalents. No Dividend Equivalents will be paid on the Performance Share Units until such time as:
(i) the Performance Period has ended; (ii) Employee has vested in the Award, and; (iii) the number of Performance Share Units earned under this Award has been certified by the Committee based on the actual performance of the Company
during the Performance Period. Reasonably promptly after all such events have occurred, the Company will pay Employee a lump-sum cash amount in payment of Dividend Equivalents based on the number of Performance Share Units earned under the Award
multiplied by the per share quarterly dividend payments made to shareholders of Company’s Common Stock during the Performance Period (without any interest or compounding). Notwithstanding the foregoing, any accumulated and unpaid Dividend
Equivalents attributable to Performance Share Units that are cancelled or forfeited will not be paid and are immediately forfeited upon cancellation of the Performance Share Units. Following the end of the Performance Period, Dividend Equivalents
will also be paid on vested Performance Share Units for which a valid deferral election has been made pursuant to Section 12. With respect to validly deferred and vested Performance Share Units, the Company will pay Dividend Equivalents in cash
at such times as dividends are paid on the Company’s outstanding shares of Common Stock. 

  
 -6-

 12. Elective Deferrals. 

(a) The Committee may establish procedures pursuant to which Employee may elect to defer, until a time or times later
than the vesting of a Performance Share Unit, receipt of all or a portion of the shares of Common Stock deliverable in respect of a Performance Share Unit, all on such terms and conditions as the Committee (or its designee) shall determine in its
sole discretion. If any such deferrals are permitted for Employee, then notwithstanding any provision of this Agreement or the Plan to the contrary, an Employee who elects such deferral shall not have any rights as a stockholder with respect to any
such deferred shares of Common Stock unless and until the date the deferral expires and certificates representing such shares are required to be delivered to Employee. The foregoing notwithstanding, no deferrals of Dividend Equivalents related to
any Performance Share Units under this Award will be permitted. Moreover, the Committee further retains the authority and discretion to modify and/or terminate existing deferral elections, procedures and distribution options. 

(b) Notwithstanding any provision to the contrary in this Agreement, if deferral of Performance Share Units is permitted,
each provision of this Agreement shall be interpreted to permit the deferral of compensation only as allowed in compliance with the requirements of Section 409A of the Internal Revenue Code and any provision that would conflict with such
requirements shall not be valid or enforceable. Employee acknowledges, without limitation, and consents that application of Section 409A of the Internal Revenue Code to this Agreement may require additional delay of payments otherwise payable
under this Agreement. Employee and the Company further hereby agree to execute such further instruments and take such further action as reasonably may be necessary to comply with Section 409A of the Internal Revenue Code. 

13. Restrictions on Transfer. 
 (a) Absent prior written consent of the Committee, the Award granted hereunder to Employee may not be sold, assigned, transferred, pledged or otherwise encumbered, whether voluntarily or involuntarily, by
operation of law or otherwise; provided, however, that the transfer of any shares of Common Stock with respect to the Performance Share Units earned hereunder shall not be restricted by virtue of this Agreement. 

(b) Consistent with the foregoing, except as contemplated by Section 14, no right or benefit under this Agreement
shall be subject to transfer, anticipation, alienation, sale, assignment, pledge, encumbrance or charge, whether voluntary, involuntary, by operation of law or otherwise, and any attempt to transfer, anticipate, alienate, sell, assign, pledge,
encumber or charge the same shall be void. No right or benefit hereunder shall in any manner be liable for or subject to any debts, contracts, liabilities or torts of the person entitled to such benefits. If Employee or his Beneficiary hereunder
shall attempt to transfer, 

  
 -7-

 
anticipate, alienate, assign, sell, pledge, encumber or charge any right or benefit hereunder, other than as contemplated by Section 14, or if any creditor shall attempt to subject the same
to a writ of garnishment, attachment, execution sequestration, or any other form of process or involuntary lien or seizure, then such attempt shall have no effect and shall be void. 

14. Assignment and Transfers. Prior to the end of the Performance Period and the delivery of the Common Stock with respect to any
Performance Share Units earned, the Award is not transferable (either voluntarily or involuntarily), other than pursuant to a domestic relations order. Employee may designate a beneficiary or beneficiaries (the “Beneficiary”) to whom the
Performance Share Units will pass upon Employee’s death and may change such designation from time to time by filing a written designation of beneficiary on such form as may be prescribed by the Company, provided that no such designation shall
be effective until filed with the Company. Following Employee’s death, the Performance Share Units will pass to the designated Beneficiary and such person will be deemed Employee for purposes of any applicable provisions of this Agreement. If
no such designation is made or if the designated Beneficiary does not survive Employee’s death, the Performance Share Units shall pass by will or, if none, then by the laws of descent and distribution. 

15. Withholding Tax. To the extent that the receipt of this Award, vesting, or the delivery of the Common Stock with respect to
any Performance Share Units earned results in a taxable event to Employee for federal or state tax purposes, Employee shall deliver to the Company at the time of such receipt, such amount of money or shares of Common Stock earned or owned by
Employee, at Employee’s election, as the Company may require to meet its obligation under applicable tax laws or regulations, and, if Employee fails to do so, the Company is authorized to withhold from any cash or other form of remuneration
then or thereafter payable to Employee any tax required to be withheld by reasons of such resulting taxation. 
 16. Changes
in Capital Structure. If the outstanding shares of Common Stock or other securities of Waste Management, Inc., or both, shall at any time be changed or exchanged by declaration of a stock dividend, stock split, combination of shares, or
recapitalization, the number of Performance Share Units shall be appropriately and equitably adjusted so as to maintain the proportionate number of shares. 
 17. Compliance with Securities Laws. The Company will not be required to deliver any shares of Common Stock pursuant to this Agreement, if, in the opinion of counsel for the Company, such issuance
would violate the Securities Act of 1933 or any other applicable federal or state securities laws or regulations. Prior to the issuance of any shares pursuant to this Agreement, the Company may require that Employee (or Employee’s legal
representative upon Employee’s death or disability) enter into such written representations, warranties and agreements as the Company may reasonably request in order to comply with applicable securities laws or with this Agreement. 

18. Employee to Have no Rights as a Stockholder. Employee shall have no rights as a stockholder with respect to any shares of
Common Stock related to this Award 

  
 -8-

 
prior to the date on which Employee is recorded as the holder of such shares of Common Stock on the records of the Company, including no right to dividends declared on the Common Stock underlying
the Award. 
 19. Successors and Assigns. 

(a) This Agreement shall bind and inure to the benefit of and be enforceable by Employee, the Company and their
respective permitted successors or assigns (including personal representatives, heirs and legatees), except that Employee may not assign any rights or obligations under this Agreement except to the extent, and in the manner, expressly permitted
herein. 
 (b) The Company shall require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it
if no such succession had taken place. 
 20. Limitation of Rights. Nothing in this Agreement or the Plan may be
construed to: 
 (a) give Employee any right to be awarded any further Performance Share Units (or other form of
stock incentive awards) other than in the sole discretion of the Committee; 
 (b) give Employee or any other
person any interest in any fund or in any specified asset or assets of the Company (other than the Award and applicable Common Stock following the vesting of such Award); or 

(c) confer upon Employee the right to continue in the employment or service of the Company. 

21. Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Texas,
without reference to principles of conflict of laws. 
 22. Severability. The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement. 
 23.
No Waiver. The failure of Employee or the Company to insist upon strict compliance with any provision of this Agreement or the failure to assert any right Employee or the Company may have under this Agreement shall not be deemed to be a
waiver of such provision or right or any other provision or right of this Agreement. 
 24. Definitions. Capitalized
