 REVERSE OF BOOK-ENTRY SECURITY 

WASTE MANAGEMENT, INC. 
 3.125% SENIOR NOTES DUE 2025 
 This Security is one of a duly authorized issue of
unsecured debentures, notes or other evidences of indebtedness of the Company (the “Debt Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to the Indenture, to which Indenture reference is
hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Debt Securities. The Debt Securities may be issued in one or more series, which
different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as
provided in the Indenture. This Security is one of a series designated as the 3.125% Senior Notes due 2025 of the Company, in initial aggregate principal amount of $600,000,000 (the “Securities”). 

 

	 	1.	Interest. 

 The Company
promises to pay interest on the principal amount of this Security at the rate of 3.125% per annum. 
 The Company will pay
interest semi-annually on March 1 and September 1 of each year (each an “Interest Payment Date”), commencing September 1, 2015. Interest on the Securities will accrue from the most recent date to which interest has been paid
or, if no interest has been paid on the Securities, from February 26, 2015. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. The Company shall pay interest (including post-petition interest in any
proceeding under any applicable bankruptcy laws) on overdue installments of interest (without regard to any applicable grace period) and on overdue principal and premium, if any, from time to time on demand at the rate of 3.125% per annum, in
each case to the extent lawful. 
  

	 	2.	Method of Payment. 

 The
Company shall pay interest on the Securities (except Defaulted Interest) to the persons who are the registered Holders at the close of business on the Regular Record Date immediately preceding the Interest Payment Date. Any such interest not so
punctually paid or duly provided for (“Defaulted Interest”) may be paid to the persons who are registered Holders at the close of business on a Special Record Date for the payment of such Defaulted Interest, or in any other lawful manner
not inconsistent with the requirements of any securities exchange on which such Securities may then be listed if such manner of payment shall be deemed practicable by the Trustee, as more fully provided in the Indenture. Except as provided below,
the Company shall pay principal and interest in such coin or currency of the United States of America as at the time of payment shall be legal tender for payment of public and private debts (“U.S. Legal Tender”). Payments in respect of a
Book-Entry Security (including principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts 

 
specified by the Depository. Payments in respect of Securities in definitive form (including principal, premium, if any, and interest) will be made at the office or agency of the Company
maintained for such purpose within the Borough of Manhattan, the City of New York, which initially will be at the corporate trust office of The Bank of New York Mellon, located at 101 Barclay Street, Floor 21W, New York, New York, 10286 or at the
option of the Company, payment of interest may be made by check mailed to the Holders on the Regular Record Date or on the Special Record Date at their addresses set forth in the Security Register of Holders. 

 

	 	3.	Paying Agent and Registrar. 

 Initially, The Bank of New York Mellon Trust Company, N.A. will act as Paying Agent and Registrar. The Company may change any Paying Agent, Registrar or co-Registrar at any time upon notice to the Trustee
and the Holders. The Company or any of its Subsidiaries may, subject to certain exceptions, act as Paying Agent, Registrar or co-Registrar. 
  

	 	4.	Indenture. 

 This Security
is one of a duly authorized issue of Debt Securities of the Company issued and to be issued in one or more series under the Indenture. 
 Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Securities include those stated in the Indenture and all indentures supplemental thereto,
those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, as in effect on the date of the Indenture, and those terms stated in the Officers’ Certificate to the Trustee, duly authorized by resolutions of the
Board of Directors of the Company on August 24, 2012 (the “Resolutions”) and the written consents of the Sole Director of Waste Management Holdings, Inc. on September 24, 2012 and February 5, 2015 (the “Consents”).
The Securities are subject to all such terms, and Holders of Securities are referred to the Indenture, all indentures supplemental thereto, said Act, said Resolutions and said Consents and Officers’ Certificate for a statement of them. The
Securities of this series are general unsecured obligations of the Company limited with an initial aggregate principal amount of $600,000,000. 
  

	 	5.	Redemption. 

 Before the
Par Call Date, the Securities will be redeemable and repayable, at the option of the Company, at any time in whole, or from time to time in part, at a Redemption Price (the “Make-Whole Price”) equal to the greater of: (i) 100% of the
principal amount of the Securities to be redeemed; or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities that would be due if such Securities matured on the Par Call Date
(exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Yield plus 20 basis points; plus, in either case,
accrued interest to the Redemption Date. 
 On or after the Par Call Date, the Securities will be redeemable and repayable, at
the option of the Company, at any time in whole, or from time to time in part, at a Redemption Price equal to 100% of the principal amount of the Securities to be redeemed plus accrued interest on the Securities to be redeemed to the Redemption
Date. 

 Securities called for redemption become due on the Redemption Date. Notices of redemption
will be mailed at least 30 but not more than 60 days before the Redemption Date to each holder of record of the Securities to be redeemed at its registered address. The notice of redemption for the Securities will state, among other things, the
amount of Securities to be redeemed, the Redemption Date, the Redemption Price or, if not ascertainable, the manner of determining the Make-Whole Price and the place(s) that payment will be made upon presentation and surrender of Securities to be
redeemed. Unless the Company defaults in payment of the Make-Whole Price, interest will cease to accrue on any Securities that have been called for redemption at the Redemption Date. If less than all the Securities are redeemed at any time, the
Trustee will select the Securities to be redeemed on a pro rata basis or by any other method the Trustee deems fair and appropriate. 
 For purposes of determining the Make-Whole Price, the following definitions are applicable: 
 “Treasury Yield” means, with respect to any Redemption Date applicable to the Securities, the rate per annum equal to the semi-annual equivalent yield to maturity (computed as of the third
Business Day immediately preceding such Redemption Date) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury Price for
such Redemption Date. 
 “Comparable Treasury Issue” means the United States Treasury security selected by an
Independent Investment Banker as having a maturity comparable to the remaining term of the Securities, calculated as if the maturity date of such notes were the Par Call Date (the “Remaining Life”), that would be utilized, at the time of
selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the Remaining Life of the Securities. 

“Independent Investment Banker” means any of Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc., Goldman,
Sachs & Co. and J.P. Morgan Securities LLC (and their respective successors), or, if all such firms are unwilling or unable to select the applicable Comparable Treasury Issue, an independent investment banking institution of national
standing appointed by the Trustee and reasonably acceptable to the Company. 
 “Comparable Treasury Price” means, with
respect to any Redemption Date, (i) the average of the Reference Treasury Dealer Quotations obtained by the Trustee for the Redemption Date, after excluding the highest and lowest of all Reference Treasury Dealer Quotations obtained, or
(ii) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations obtained by the Trustee. 
 “Par Call Date” means December 1, 2024. 

 “Reference Treasury Dealer” means (i) each of Credit Suisse Securities (USA)
LLC, Deutsche Bank Securities Inc., Goldman, Sachs & Co. and J.P. Morgan Securities LLC (and their respective successors), unless any of them ceases to be a primary U.S. government securities dealer in New York City (a “Primary
Treasury Dealer”), in which case the Company will substitute therefor another Primary Treasury Dealer, and (ii) any other Primary Treasury Dealer selected by the Company. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date for the
Securities, an average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue for the Securities (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such
Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 
 Except
as set forth above, the Securities will not be redeemable prior to their Stated Maturity and will not be entitled to the benefit of any sinking fund. 
 The Securities may be redeemed in part in a minimum principal amount of $2,000, or any integral multiple of $1,000 in excess thereof. 

Any such redemption will also comply with Article Eleven of the Indenture. 

 

	 	6.	Change of Control Offer. 

If a Change of Control Triggering Event occurs, unless the Company has exercised its option to redeem the Securities as described in
Section 5, the Company shall make an offer (a “Change of Control Offer”) to each Holder of the Securities to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s
Securities on the terms set forth herein. In a Change of Control Offer, the Company shall offer payment in cash equal to 101% of the aggregate principal amount of Securities repurchased (a “Change of Control Payment”), plus accrued and
unpaid interest, if any, on the Securities repurchased to the date of repurchase, subject to the right of holders of record on the applicable record date to receive interest due on the next Interest Payment Date. 

Within 30 days following any Change of Control Triggering Event or, at the Company’s option, prior to any Change of Control, but
after public announcement of the transaction that constitutes or may constitute the Change of Control, the Company shall mail a notice to Holders of the Securities describing the transaction that constitutes or may constitute the Change of Control
Triggering Event and offer to repurchase such Securities on the date specified in the applicable notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (a “Change of Control Payment
Date”). The notice may, if mailed prior to the date of consummation of the Change of Control, state that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring on or prior to the applicable Change of
Control Payment Date. 

 Upon the Change of Control Payment Date, the Company shall, to the extent lawful:

  

	 	•	 	 accept for payment all Securities or portions of Securities properly tendered and not withdrawn pursuant to the Change of Control Offer;

  

	 	•	 	 deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities or portions of Securities properly
tendered; and 

  

	 	•	 	 deliver or cause to be delivered to the Trustee the Securities properly accepted together with an Officers’ Certificate stating the aggregate
principal amount of Securities or portions of Securities being repurchased. 

 The Company need not make a
Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the third
party repurchases all Securities properly tendered and not withdrawn under its offer. In addition, the Company shall not repurchase any Securities if there has occurred and is continuing on the Change of Control Payment Date an Event of Default
under the Indenture, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event. 
 The Company will comply with the applicable requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the ‘‘Exchange Act’’), and any other securities laws and
regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Securities as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or
regulations conflict with the Change of Control Offer provisions of this Security, the Company may comply with those securities laws and regulations and, if so, will not be deemed to have breached its obligations under the Change of Control Offer
provisions of this Security by virtue of any such conflict. 
 For purposes of the Change of Control Offer provisions of the
Securities, the following terms are applicable: 
 “Change of Control” means the occurrence of any of the following:
(1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or more series of related transactions, of all or substantially all of the Company’s assets and the
assets of its Subsidiaries, taken as a whole, to any person, other than the Company or one of its Subsidiaries; (2) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any
person becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the outstanding Voting Stock of the Company or other Voting Stock into which the Company’s Voting
Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares; (3) the Company consolidates with, or merges with or into, any person, or any person consolidates with, or merges with or into,
the Company, in any such event pursuant to a transaction in which any of the outstanding Voting Stock of the Company or the Voting Stock of such other person is converted into or exchanged for cash, securities or other property, other than any such
transaction where the shares of the Voting Stock of the Company outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving person or

 
any direct or indirect parent company of the surviving person, measured by voting power rather than number of shares, immediately after giving effect to such transaction; (4) the first day
on which a majority of the members of the Board of Directors of the Company are not Continuing Directors; or (5) the adoption of a plan relating to the liquidation or dissolution of the Company. 

Notwithstanding the preceding, a transaction will not be deemed to involve a Change of Control under clause (2) above if
(i) the Company becomes a direct or indirect wholly-owned subsidiary of a holding company and (ii)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same
as the holders of Voting Stock of the Company immediately prior to that transaction or (B) immediately following that transaction no person (other than a holding company satisfying the requirements of this sentence) is the beneficial owner,
directly or indirectly, of more than 50% of the Voting Stock of such holding company. The term ‘‘person,’’ as used in this definition, has the meaning given thereto in Section 13(d)(3) of the Exchange Act. 

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Rating Event. 

“Continuing Directors” means, as of any date of determination, any member of the Board of Directors of the Company who
(1) was a member of such Board of Directors on the date the Securities were issued or (2) was nominated for election, elected or appointed to such Board of Directors with the approval of a majority of the Continuing Directors who were
members of such Board of Directors at the time of such nomination, election or appointment (either by a specific vote or by approval of the Company’s proxy statement in which such member was named as a nominee for election as a director,
without objection to such nomination). 
 “Fitch” means Fitch Inc. and its successors. 

“Investment Grade Rating” means a rating equal to or higher than BBB- (or the equivalent) by Fitch, Baa3 (or the equivalent) by
Moody’s and BBB- (or the equivalent) by S&P, and the equivalent investment grade credit rating from any replacement Rating Agency or Rating Agencies selected by the Company. 

“Moody’s” means Moody’s Investors Service, Inc. and its successors. 

“Rating Agencies” means (1) each of Fitch, Moody’s and S&P and (2) if any of Fitch, Moody’s or S&P
ceases to rate the Securities or fails to make a rating of the Securities publicly available for reasons outside of the Company’s control, a ‘‘nationally recognized statistical rating organization’’ within the meaning of
Section 3(a)(62) of the Exchange Act selected by the Company (as certified by a resolution of our Board of Directors) as a replacement agency for Fitch, Moody’s or S&P, or all of them, as the case may be. 

“Rating Event” means the rating on the Securities is lowered by at least two of the three Rating Agencies and the Securities
are rated below an Investment Grade Rating by at least two of the three Rating Agencies, in any case on any day during the period (which period will be extended so long as the rating of the Securities is under publicly announced consideration for a
possible downgrade by any of the rating agencies) commencing 60 days prior to the first public notice of the occurrence of a Change of Control or the Company’s intention to effect a Change of Control and ending 60 days following consummation of

	 	7.	Denominations; Transfer; Exchange. 

 The Securities are issued in registered form, without coupons, in a minimum denomination of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may register the transfer of, or exchange,
Securities in accordance with the Indenture. The Securities Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture.

  

	 	8.	Person Deemed Owners. 

The registered Holder of a Security may be treated as the owner of it for all purposes. 

 

	 	9.	Amendment; Supplement; Waiver. 

 Subject to certain exceptions, the Indenture may be amended or supplemented, and any existing Event of Default or compliance with any provision may be waived, with the consent of the Holders of a majority
in principal amount of the Outstanding Securities of each series affected. Without consent of any Holder, the parties thereto may amend or supplement the Indenture or the Securities to, among other things, cure any ambiguity, defect or
inconsistency, or make any other change that does not adversely affect the interests of any Holder of a Security. Any such consent or waiver by the Holder of this Security (unless revoked as provided in the Indenture) shall be conclusive and binding
upon such Holder and upon all future Holders and owners of this Security and any Securities which may be issued in exchange or substitution herefor, irrespective of whether or not any notation thereof is made upon this Security or such other
Securities. 
  

	 	10.	Defaults and Remedies. 

If an Event of Default with respect to the Securities occurs and is continuing, then in every such case the Trustee or the Holders of not
less than 25% in principal amount of the Securities then Outstanding may declare the principal amount of all the Securities to be due and payable immediately in the manner and with the effect provided in the Indenture. Notwithstanding the preceding
sentence, however, if at any time after such a declaration of acceleration has been made and before judgment or decree for payment of the money due has been obtained by the Trustee as provided in the Indenture, the Holders of a majority in principal
amount of the Outstanding Securities, by written notice to the Company and to the Trustee, may rescind and annul such declaration and its consequences if (1) the Company has paid or deposited with the Trustee a sum sufficient to pay
(A) all overdue interest on all Securities, (B) 

 
the principal of (and premium, if any, on) any Securities which has become due otherwise than by such declaration of acceleration and any interest thereon at the rate prescribed therefor herein,
(C) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate prescribed therefor herein, and (D) all sums paid or advanced by the Trustee and the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel and (2) all Events of Default under the Indenture with respect to the Securities, other than the nonpayment of the principal of Securities which has become due solely by such declaration
acceleration, shall have been cured or shall have been waived. No such rescission shall affect any subsequent Event of Default or shall impair any right consequent thereon. Holders of Securities may not enforce the Indenture or the Securities except
as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then
outstanding may direct the Trustee in its exercise of any trust or power. 
  

	 	11.	Trustee Dealings with Company. 

 The Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company and its Affiliates and any subsidiary of the
Company’s Affiliates, and may otherwise deal with the Company and its Affiliates as if it were not the Trustee. 
  

	 	12.	Authentication. 

This Security shall not be valid until the Trustee or authenticating agent signs the certificate of authentication on the other side of
this Security. 
  

	 	13.	Abbreviations and Defined Terms. 

 Customary abbreviations may be used in the name of a Holder of a Security or an assignee, such as: TEN COM (tenant in common), TEN ENT (tenants by the entireties), JT TEN (joint tenants with right of
survivorship and not as tenants in common), CUST (Custodian), and U/G/M/A (Uniform Gifts to Minors Act). 
  

	 	14.	CUSIP Numbers. 

 Pursuant
to a recommendation promulgated by the Committee on Uniform Note Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the
accuracy of such number as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon. 
  

	 	15.	Absolute Obligation. 

 No
reference herein to the Indenture and no provision of this Security or the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Security in
the manner, at the respective times, at the rate and in the coin or currency herein prescribed.

under or upon any obligation, covenant or agreement contained in the Indenture or in any Security, or because of any indebtedness evidenced thereby, shall be had against any incorporator, past, present or future stockholder, officer or director, as
such of the Company or of any successor, either directly or through the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any
assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Security by the Holder and as part of the consideration for the issue of the Security.

 REVERSE OF BOOK-ENTRY SECURITY 

WASTE MANAGEMENT, INC. 
 3.900% SENIOR NOTES DUE 2035 
 This Security is one of a duly authorized issue of
unsecured debentures, notes or other evidences of indebtedness of the Company (the “Debt Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to the Indenture, to which Indenture reference is
hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Debt Securities. The Debt Securities may be issued in one or more series, which
different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as
provided in the Indenture. This Security is one of a series designated as the 3.900% Senior Notes due 2035 of the Company, in initial aggregate principal amount of $450,000,000 (the “Securities”). 

 

	 	1.	Interest. 

 The Company
promises to pay interest on the principal amount of this Security at the rate of 3.900% per annum. 
 The Company will pay
interest semi-annually on March 1 and September 1 of each year (each an “Interest Payment Date”), commencing September 1, 2015. Interest on the Securities will accrue from the most recent date to which interest has been paid
or, if no interest has been paid on the Securities, from February 26, 2015. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. The Company shall pay interest (including post-petition interest in any
proceeding under any applicable bankruptcy laws) on overdue installments of interest (without regard to any applicable grace period) and on overdue principal and premium, if any, from time to time on demand at the rate of 3.900% per annum, in
each case to the extent lawful. 
  

	 	2.	Method of Payment. 

 The
Company shall pay interest on the Securities (except Defaulted Interest) to the persons who are the registered Holders at the close of business on the Regular Record Date immediately preceding the Interest Payment Date. Any such interest not so
punctually paid or duly provided for (“Defaulted Interest”) may be paid to the persons who are registered Holders at the close of business on a Special Record Date for the payment of such Defaulted Interest, or in any other lawful manner
not inconsistent with the requirements of any securities exchange on which such Securities may then be listed if such manner of payment shall be deemed practicable by the Trustee, as more fully provided in the Indenture. Except as provided below,
the Company shall pay principal and interest in such coin or currency of the United States of America as at the time of payment shall be legal tender for payment of public and private debts (“U.S. Legal Tender”). Payments in respect of a
Book-Entry Security (including principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts 

 
specified by the Depository. Payments in respect of Securities in definitive form (including principal, premium, if any, and interest) will be made at the office or agency of the Company
maintained for such purpose within the Borough of Manhattan, the City of New York, which initially will be at the corporate trust office of The Bank of New York Mellon, located at 101 Barclay Street, Floor 21W, New York, New York, 10286 or at the
option of the Company, payment of interest may be made by check mailed to the Holders on the Regular Record Date or on the Special Record Date at their addresses set forth in the Security Register of Holders. 

 

	 	3.	Paying Agent and Registrar. 

 Initially, The Bank of New York Mellon Trust Company, N.A. will act as Paying Agent and Registrar. The Company may change any Paying Agent, Registrar or co-Registrar at any time upon notice to the Trustee
and the Holders. The Company or any of its Subsidiaries may, subject to certain exceptions, act as Paying Agent, Registrar or co-Registrar. 
  

	 	4.	Indenture. 

 This Security
is one of a duly authorized issue of Debt Securities of the Company issued and to be issued in one or more series under the Indenture. 
 Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Securities include those stated in the Indenture and all indentures supplemental thereto,
those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, as in effect on the date of the Indenture, and those terms stated in the Officers’ Certificate to the Trustee, duly authorized by resolutions of the
Board of Directors of the Company on August 24, 2012 (the “Resolutions”) and the written consents of the Sole Director of Waste Management Holdings, Inc. on September 24, 2012 and February 5, 2015 (the “Consents”).
The Securities are subject to all such terms, and Holders of Securities are referred to the Indenture, all indentures supplemental thereto, said Act, said Resolutions and said Consents and Officers’ Certificate for a statement of them. The
Securities of this series are general unsecured obligations of the Company limited with an initial aggregate principal amount of $450,000,000. 
  

	 	5.	Redemption. 

 Before the
Par Call Date, the Securities will be redeemable and repayable, at the option of the Company, at any time in whole, or from time to time in part, at a Redemption Price (the “Make-Whole Price”) equal to the greater of: (i) 100% of the
principal amount of the Securities to be redeemed; or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities that would be due if such Securities matured on the Par Call Date
(exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Yield plus 20 basis points; plus, in either case,
accrued interest to the Redemption Date. 
 On or after the Par Call Date, the Securities will be redeemable and repayable, at
the option of the Company, at any time in whole, or from time to time in part, at a Redemption Price equal to 100% of the principal amount of the Securities to be redeemed plus accrued interest on the Securities to be redeemed to the Redemption
Date. 

 Securities called for redemption become due on the Redemption Date. Notices of redemption
will be mailed at least 30 but not more than 60 days before the Redemption Date to each holder of record of the Securities to be redeemed at its registered address. The notice of redemption for the Securities will state, among other things, the
amount of Securities to be redeemed, the Redemption Date, the Redemption Price or, if not ascertainable, the manner of determining the Make-Whole Price and the place(s) that payment will be made upon presentation and surrender of Securities to be
redeemed. Unless the Company defaults in payment of the Make-Whole Price, interest will cease to accrue on any Securities that have been called for redemption at the Redemption Date. If less than all the Securities are redeemed at any time, the
Trustee will select the Securities to be redeemed on a pro rata basis or by any other method the Trustee deems fair and appropriate. 
 For purposes of determining the Make-Whole Price, the following definitions are applicable: 
 “Treasury Yield” means, with respect to any Redemption Date applicable to the Securities, the rate per annum equal to the semi-annual equivalent yield to maturity (computed as of the third
Business Day immediately preceding such Redemption Date) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury Price for
such Redemption Date. 
 “Comparable Treasury Issue” means the United States Treasury security selected by an
Independent Investment Banker as having a maturity comparable to the remaining term of the Securities, calculated as if the maturity date of such notes were the Par Call Date (the “Remaining Life”), that would be utilized, at the time of
selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the Remaining Life of the Securities. 

“Independent Investment Banker” means any of Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc., Goldman,
Sachs & Co. and J.P. Morgan Securities LLC (and their respective successors), or, if all such firms are unwilling or unable to select the applicable Comparable Treasury Issue, an independent investment banking institution of national
standing appointed by the Trustee and reasonably acceptable to the Company. 
 “Comparable Treasury Price” means, with
respect to any Redemption Date, (i) the average of the Reference Treasury Dealer Quotations obtained by the Trustee for the Redemption Date, after excluding the highest and lowest of all Reference Treasury Dealer Quotations obtained, or
(ii) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations obtained by the Trustee. 
 “Par Call Date” means September 1, 2034. 

 “Reference Treasury Dealer” means (i) each of Credit Suisse Securities (USA)
LLC, Deutsche Bank Securities Inc., Goldman, Sachs & Co. and J.P. Morgan Securities LLC (and their respective successors), unless any of them ceases to be a primary U.S. government securities dealer in New York City (a “Primary
Treasury Dealer”), in which case the Company will substitute therefor another Primary Treasury Dealer, and (ii) any other Primary Treasury Dealer selected by the Company. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date for the
Securities, an average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue for the Securities (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such
Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 
 Except
as set forth above, the Securities will not be redeemable prior to their Stated Maturity and will not be entitled to the benefit of any sinking fund. 
 The Securities may be redeemed in part in a minimum principal amount of $2,000, or any integral multiple of $1,000 in excess thereof. 

Any such redemption will also comply with Article Eleven of the Indenture. 

 

	 	6.	Change of Control Offer. 

If a Change of Control Triggering Event occurs, unless the Company has exercised its option to redeem the Securities as described in
Section 5, the Company shall make an offer (a “Change of Control Offer”) to each Holder of the Securities to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s
Securities on the terms set forth herein. In a Change of Control Offer, the Company shall offer payment in cash equal to 101% of the aggregate principal amount of Securities repurchased (a “Change of Control Payment”), plus accrued and
unpaid interest, if any, on the Securities repurchased to the date of repurchase, subject to the right of holders of record on the applicable record date to receive interest due on the next Interest Payment Date. 

Within 30 days following any Change of Control Triggering Event or, at the Company’s option, prior to any Change of Control, but
after public announcement of the transaction that constitutes or may constitute the Change of Control, the Company shall mail a notice to Holders of the Securities describing the transaction that constitutes or may constitute the Change of Control
Triggering Event and offer to repurchase such Securities on the date specified in the applicable notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (a “Change of Control Payment
Date”). The notice may, if mailed prior to the date of consummation of the Change of Control, state that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring on or prior to the applicable Change of
Control Payment Date. 

 Upon the Change of Control Payment Date, the Company shall, to the extent lawful:

  

	 	•	 	 accept for payment all Securities or portions of Securities properly tendered and not withdrawn pursuant to the Change of Control Offer;

  

	 	•	 	 deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities or portions of Securities properly
tendered; and 

  

	 	•	 	 deliver or cause to be delivered to the Trustee the Securities properly accepted together with an Officers’ Certificate stating the aggregate
principal amount of Securities or portions of Securities being repurchased. 

 The Company need not make a
Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the third
party repurchases all Securities properly tendered and not withdrawn under its offer. In addition, the Company shall not repurchase any Securities if there has occurred and is continuing on the Change of Control Payment Date an Event of Default
under the Indenture, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event. 
 The Company will comply with the applicable requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the ‘‘Exchange Act’’), and any other securities laws and
regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Securities as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or
regulations conflict with the Change of Control Offer provisions of this Security, the Company may comply with those securities laws and regulations and, if so, will not be deemed to have breached its obligations under the Change of Control Offer
provisions of this Security by virtue of any such conflict. 
 For purposes of the Change of Control Offer provisions of the
Securities, the following terms are applicable: 
 “Change of Control” means the occurrence of any of the following:
(1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or more series of related transactions, of all or substantially all of the Company’s assets and the
assets of its Subsidiaries, taken as a whole, to any person, other than the Company or one of its Subsidiaries; (2) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any
person becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the outstanding Voting Stock of the Company or other Voting Stock into which the Company’s Voting
Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares; (3) the Company consolidates with, or merges with or into, any person, or any person consolidates with, or merges with or into,
the Company, in any such event pursuant to a transaction in which any of the outstanding Voting Stock of the Company or the Voting Stock of such other person is converted into or exchanged for cash, securities or other property, other than any such
transaction where the shares of the Voting Stock of the Company outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving person or

 
any direct or indirect parent company of the surviving person, measured by voting power rather than number of shares, immediately after giving effect to such transaction; (4) the first day
on which a majority of the members of the Board of Directors of the Company are not Continuing Directors; or (5) the adoption of a plan relating to the liquidation or dissolution of the Company. 

Notwithstanding the preceding, a transaction will not be deemed to involve a Change of Control under clause (2) above if
(i) the Company becomes a direct or indirect wholly-owned subsidiary of a holding company and (ii)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same
as the holders of Voting Stock of the Company immediately prior to that transaction or (B) immediately following that transaction no person (other than a holding company satisfying the requirements of this sentence) is the beneficial owner,
directly or indirectly, of more than 50% of the Voting Stock of such holding company. The term ‘‘person,’’ as used in this definition, has the meaning given thereto in Section 13(d)(3) of the Exchange Act. 

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Rating Event. 

“Continuing Directors” means, as of any date of determination, any member of the Board of Directors of the Company who
(1) was a member of such Board of Directors on the date the Securities were issued or (2) was nominated for election, elected or appointed to such Board of Directors with the approval of a majority of the Continuing Directors who were
members of such Board of Directors at the time of such nomination, election or appointment (either by a specific vote or by approval of the Company’s proxy statement in which such member was named as a nominee for election as a director,
without objection to such nomination). 
 “Fitch” means Fitch Inc. and its successors. 

“Investment Grade Rating” means a rating equal to or higher than BBB- (or the equivalent) by Fitch, Baa3 (or the equivalent) by
Moody’s and BBB- (or the equivalent) by S&P, and the equivalent investment grade credit rating from any replacement Rating Agency or Rating Agencies selected by the Company. 

“Moody’s” means Moody’s Investors Service, Inc. and its successors. 

“Rating Agencies” means (1) each of Fitch, Moody’s and S&P and (2) if any of Fitch, Moody’s or S&P
ceases to rate the Securities or fails to make a rating of the Securities publicly available for reasons outside of the Company’s control, a ‘‘nationally recognized statistical rating organization’’ within the meaning of
Section 3(a)(62) of the Exchange Act selected by the Company (as certified by a resolution of our Board of Directors) as a replacement agency for Fitch, Moody’s or S&P, or all of them, as the case may be. 

“Rating Event” means the rating on the Securities is lowered by at least two of the three Rating Agencies and the Securities
are rated below an Investment Grade Rating by at least two of the three Rating Agencies, in any case on any day during the period (which period will be extended so long as the rating of the Securities is under publicly announced consideration for a
possible downgrade by any of the rating agencies) commencing 60 days prior to the first public notice of the occurrence of a Change of Control or the Company’s intention to effect a Change of Control and ending 60 days following consummation of
such Change of Control. 

 “S&P” means Standard & Poor’s Ratings Services, a division of
The McGraw-Hill Companies, Inc., and its successors. 
 “Voting Stock” means, with respect to any specified
‘‘person’’ (as that term is used in Section 13(d)(3) of the Exchange Act) as of any date, the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such
person. 
  

	 	7.	Denominations; Transfer; Exchange. 

 The Securities are issued in registered form, without coupons, in a minimum denomination of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may register the transfer of, or exchange,
Securities in accordance with the Indenture. The Securities Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture.

  

	 	8.	Person Deemed Owners. 

The registered Holder of a Security may be treated as the owner of it for all purposes. 

 

	 	9.	Amendment; Supplement; Waiver. 

 Subject to certain exceptions, the Indenture may be amended or supplemented, and any existing Event of Default or compliance with any provision may be waived, with the consent of the Holders of a majority
in principal amount of the Outstanding Securities of each series affected. Without consent of any Holder, the parties thereto may amend or supplement the Indenture or the Securities to, among other things, cure any ambiguity, defect or
inconsistency, or make any other change that does not adversely affect the interests of any Holder of a Security. Any such consent or waiver by the Holder of this Security (unless revoked as provided in the Indenture) shall be conclusive and binding
upon such Holder and upon all future Holders and owners of this Security and any Securities which may be issued in exchange or substitution herefor, irrespective of whether or not any notation thereof is made upon this Security or such other
Securities. 
  

	 	10.	Defaults and Remedies. 

If an Event of Default with respect to the Securities occurs and is continuing, then in every such case the Trustee or the Holders of not
less than 25% in principal amount of the Securities then Outstanding may declare the principal amount of all the Securities to be due and payable immediately in the manner and with the effect provided in the Indenture. Notwithstanding the preceding
sentence, however, if at any time after such a declaration of acceleration has been made and before judgment or decree for payment of the money due has been obtained by the Trustee as provided in the Indenture, the Holders of a majority in principal
amount of the Outstanding Securities, by written notice to the Company and to the Trustee, may rescind and annul such declaration and its consequences if (1) the Company has paid or deposited with the Trustee a sum sufficient to pay
(A) all overdue interest on all Securities, (B)

 
the principal of (and premium, if any, on) any Securities which has become due otherwise than by such declaration of acceleration and any interest thereon at the rate prescribed therefor herein,
(C) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate prescribed therefor herein, and (D) all sums paid or advanced by the Trustee and the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel and (2) all Events of Default under the Indenture with respect to the Securities, other than the nonpayment of the principal of Securities which has become due solely by such declaration
acceleration, shall have been cured or shall have been waived. No such rescission shall affect any subsequent Event of Default or shall impair any right consequent thereon. Holders of Securities may not enforce the Indenture or the Securities except
as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then
outstanding may direct the Trustee in its exercise of any trust or power. 
  

	 	11.	Trustee Dealings with Company. 

 The Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company and its Affiliates and any subsidiary of the
Company’s Affiliates, and may otherwise deal with the Company and its Affiliates as if it were not the Trustee. 
  

	 	12.	Authentication. 

 This
Security shall not be valid until the Trustee or authenticating agent signs the certificate of authentication on the other side of this Security. 
  

	 	13.	Abbreviations and Defined Terms. 

 Customary abbreviations may be used in the name of a Holder of a Security or an assignee, such as: TEN COM (tenant in common), TEN ENT (tenants by the entireties), JT TEN (joint tenants with right of
survivorship and not as tenants in common), CUST (Custodian), and U/G/M/A (Uniform Gifts to Minors Act). 
  

	 	14.	CUSIP Numbers. 

 Pursuant
to a recommendation promulgated by the Committee on Uniform Note Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the
accuracy of such number as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon. 
  

	 	15.	Absolute Obligation. 

 No
reference herein to the Indenture and no provision of this Security or the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Security in
the manner, at the respective times, at the rate and in the coin or currency herein prescribed. 

	 	16.	No Recourse. 

 No recourse
under or upon any obligation, covenant or agreement contained in the Indenture or in any Security, or because of any indebtedness evidenced thereby, shall be had against any incorporator, past, present or future stockholder, officer or director, as
such of the Company or of any successor, either directly or through the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any
assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Security by the Holder and as part of the consideration for the issue of the Security. 

 

	 	17.	Governing Law. 

 This
Security shall be construed in accordance with and governed by the laws of the State of New York. 
  

	 	18.	Guarantee. 

 The
Securities will be fully and unconditionally guaranteed on a senior basis by the Company’s wholly owned subsidiary, Waste Management Holdings, Inc., pursuant to the terms and conditions of a Guarantee Agreement dated February 26, 2015 (the
“Guarantee”). The amount of the Guarantee will be limited to the extent required under applicable fraudulent conveyance laws to cause the Guarantee to be enforceable. The terms and conditions of the Guarantee shall continue in full force
and effect for the benefit of holders of the Securities until release thereof as set forth in Section 6 of the Guarantee.
