shall have the meanings assigned to such terms in the Assumed Purchase Agreement (as hereinafter defined). 

 

Recitals:

 

Whereas,
WCN and certain of its Subsidiaries and the purchasers named therein are parties to that certain Master Note Purchase Agreement,
dated as of July 15, 2008, as amended by that certain Amendment No. 1 to Master Note Purchase Agreement dated as of July 20,

Agreement”);

 

Whereas,
on January 18, 2016, Progressive Waste Solutions Ltd., a corporation organized under the laws of Ontario (“Progressive
Waste”), Water Merger Sub LLC, a Delaware limited liability company and a direct or indirect wholly-owned subsidiary
of Progressive Waste (“Merger Sub”), and WCN entered into an Agreement and Plan of Merger, pursuant to which,
subject to the terms and conditions contained therein, Merger Sub has merged with and into WCN (the “Merger”)
as a direct or indirect wholly-owned subsidiary of Progressive Waste;

 

Whereas,
as a result of the Merger, the Parent has become the direct or indirect parent company of WCN and its Subsidiaries;

 

Whereas,
the Purchase Agreement requires, as a condition to the effectiveness of the Assumed Purchase Agreement, that the Parent execute
and deliver this Agreement; and

 

Whereas,
the Parent has agreed to execute and deliver this Agreement and assume the obligations of WCN under the Purchase Agreement in exchange
for the Assumption Note (as defined below);

 

     

     

    

 

Now,
Therefore, in consideration of the premises and other good and valuable consideration, the receipt and sufficiency of which
is hereby acknowledged, the Parent hereby agrees as follows:

 

Section
1.Assumption and Amendment; Consideration for Assumption.

 

(a)The Parent hereby,
unconditionally and irrevocably, assumes in full and agrees to perform and observe each and every one of the covenants, rights,
promises, agreements, terms, conditions, obligations, duties and liabilities of “the Company”, any “Obligor”
or the “Obligors” under the Assumed Purchase Agreement and the Notes, including all extensions, modifications, substitutions,
amendments and renewals thereof (collectively, the “Assumed Obligations”). It is understood that, substantially
concurrently with the execution of this Agreement, WCN shall execute a Subsidiary Guaranty (as defined in the Assumed Purchase
Agreement) and become a guarantor of the Assumed Obligations.

 

(b)In connection
with the foregoing assumption, the Purchase Agreement is hereby amended to delete the stricken text (indicated textually in the
same manner as the following example: stricken text) and to add the double−underlined
text (indicated textually in the same manner as the following example: double−underlined
text) as set forth in the composite conformed copy of the Purchase Agreement attached hereto as Exhibit A
(the “Assumed Purchase Agreement”). Upon the request of any holder of outstanding Notes, the Parent shall
issue a replacement Note in exchange for such holder’s existing outstanding Note with ten (10) Business Days of any such
request.

 

(c)The Parent and
WCN shall pay, indemnify and save harmless each holder of Notes from and against any and all reasonable and documented out-of-pocket
costs and expenses (including reasonable and documented out-of-pocket attorneys’ fees of one special counsel for the holders,
as a group), liabilities, claims, demands or judgments arising from or out of the assumption by the Parent of the obligations of
WCN under the Notes and the Purchase Agreement in exchange for the Assumption Note, including, without limitation, any income tax
owed by the holders of Notes as a result of the issuance of new Notes by the Parent in exchange for the Notes originally issued
by WCN constituting a taxable event on the date of such assumption for income tax purposes, except to the extent such liabilities,
claims, demands or judgments resulted from the gross negligence, bad faith or willful misconduct of such holder. The indemnification
contained in this Section 1(c) shall survive the payment or transfer of any Note and the termination of the Purchase Agreement.

 

(d)As consideration
for the assumption by the Parent of the Assumed Obligations pursuant to Section 1(a) of this Agreement, WCN shall issue to the
Parent its 5.9% note in the principal amount of $835,000,000 due 2026 and dated as of the date hereof, between WCN, as the issuer,
and the Parent, as the creditor (the “Assumption Note”).

 

Section
2.  Representations and Warranties.

 

The Parent hereby represents
and warrants to the holders as follows:

    -2- 

     

    

 

 

(a)This Agreement
has been duly authorized by all necessary corporate action by the Parent, and this Agreement constitutes a legal, valid and binding
obligation of the Parent enforceable against the Parent in accordance with its terms, except (a) as such enforceability may
be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement
of creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered
in a proceeding in equity or at law), and (b) to the extent that availability of the remedy of specific performance or injunction
relief is subject to the discretion of the court before which any proceeding therefor may be brought.

 

(b)No consent,
approval or authorization of, or registration, filing or declaration with, any Governmental Authority is required in connection
with the execution, delivery or performance by the Parent or its Subsidiaries of this Agreement and the performance by the Parent
or its Subsidiaries of the Assumed Purchase Agreement.

 

(c)The execution,
delivery and performance by the Parent of this Agreement and the performance by the Parent or its Subsidiaries of the Assumed Purchase
Agreement will not (i) contravene, result in any breach of, or constitute a default under, or result in the creation of any
Lien in respect of any property of the Parent or any of its Subsidiaries under the Bank Credit Agreement, the 2016 NPA or any agreement
listed on Schedule 2, or an applicable corporate charter, memorandum of association, articles of association, regulations or by-laws
or shareholders agreement, (ii) conflict with or result in a breach of any of the terms, conditions or provisions of any order,
judgment, decree or ruling of any court, arbitrator or Governmental Authority applicable to the Parent or any such Subsidiary or
(iii) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to the Parent
or any such Subsidiary.

 

(d)The payment
obligations of the Parent and the Subsidiary Guarantors under the Assumed Purchase Agreement and the Notes rank at least pari
passu, without preference or priority, with all other unsecured and unsubordinated Indebtedness of the Parent and such Subsidiary
Guarantors.

 

(e)Immediately
before or after giving effect to this Agreement, no Default or Event of Default has occurred and is continuing.

 

(f)None of the
Parent nor any Subsidiary has paid or agreed to pay any fees or other consideration to any holder of Indebtedness, in its capacity
as a holder of such Indebtedness, of WCN and its Subsidiaries to permit the Parent to assume the obligations of WCN and its Subsidiaries
under the documents relating to such Indebtedness, except for (x) the amendments to the Purchase Agreement in connection with
the Merger Transactions and (y) repayment of all or a portion of such Indebtedness and customary and usual fees paid in connection
with entering into a new Bank Credit Agreement and, in each case, out-of-pocket expenses, including attorneys’ fees, incurred
in connection therewith.

representations and warranties set forth in Exhibit B hereto are hereby incorporated
into this Section 2 with the same force and effect as if set out in this Section 2 in full.

organized, validly existing and in good standing under the laws of its jurisdiction of organization, and is duly qualified as a
foreign corporation and is in good standing in each jurisdiction in which such qualification is required by law, other than those

authority to own or hold under lease the properties it purports to own or hold under lease, to transact the business it transacts
and proposes to transact, to execute and deliver this Agreement and the Series 2008A Notes and to perform the provisions hereof
and thereof.

 

Section 5.2.          Authorization,
Etc. This Agreement and the Series 2008A Notes have been duly authorized by all necessary corporate (or equivalent company
or partnership) action on the part of each Obligor, and this Agreement constitutes, and upon execution and delivery thereof each
Series 2008A Note will constitute, a legal, valid and binding obligation of each Obligor enforceable against each Obligor in accordance
with its terms, except (a) as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium
or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless
of whether such enforceability is considered in a proceeding in equity or at law), and (b) to the extent that availability of the
remedy of specific performance or injunctive relief is subject to the discretion of the court before which any proceeding therefore
may be brought.

 

Section 5.3.          Disclosure.

the Obligors in connection with the transactions contemplated hereby and identified in Schedule 5.3, and the financial statements

the “Disclosure Documents”), taken as a whole, do not contain any untrue statement of a material fact or omit

were made. Except as disclosed in the Disclosure Documents, since December 31, 2007 there has been no change in the financial
condition, operations, business, properties or prospects of the Obligors except changes that individually or in the aggregate would
not reasonably be expected to have a Material Adverse Effect. There is no fact known to any Obligor that would reasonably be expected
to have a Material Adverse Effect that has not been set forth herein or in the Disclosure Documents.

the respective dates specified in such Schedule and the consolidated results of their operations and cash flows for the respective
periods so specified and have been prepared in accordance with GAAP consistently applied throughout the periods involved except
as set forth in the notes thereto (subject, in the case of any interim financial statements, to normal year-end adjustments). The
Company and its Subsidiaries do not have any Material liabilities that are not disclosed on such financial statements or otherwise
disclosed in the Disclosure Documents.

 

Section 5.6.          Compliance
with Laws, Other Instruments, Etc. The execution, delivery and performance by each Obligor of this Agreement and the Series
2008A Notes will not (i) contravene, result in any breach of, or constitute a default under, or result in the creation of

is bound or by which any Obligor or any Subsidiary or any of their respective properties may be bound or affected, (ii) conflict
with or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any court,

Section 5.7.          Governmental
Authorizations, Etc. No consent, approval or authorization of, or registration, filing or declaration with, any Governmental

Observance of Agreements, Statutes and Orders. (a) There are no actions, suits, investigations or proceedings pending or, to
the knowledge of any Obligor, threatened against any Obligor or any property of any Obligor in any court or before any arbitrator

which default or violation, individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect.

 

Section 5.9.          Taxes.
The Obligors have filed all tax returns that are required to have been filed in any jurisdiction (unless, and only to the extent
that, such Obligor has set aside on its books provisions reasonably adequate for the payment of all unpaid and unreported taxes),
and have paid all taxes shown to be due and payable on such returns and all other taxes and assessments levied upon them or their
properties, assets, income or franchises, to the extent such taxes and assessments have become due and payable and before they
have become delinquent, except for any taxes and assessments (i) the amount of which is not individually or in the aggregate Material
or (ii) the amount, applicability or validity of which is currently being contested in good faith by appropriate proceedings and
with respect to which any Obligor or a Subsidiary, as the case may be, has established adequate reserves in accordance with GAAP.
None of the Obligors knows of any basis for any other tax or assessment that would reasonably be expected to have a Material Adverse
Effect. The charges, accruals and reserves on the books of the Company and its Subsidiaries in respect of Federal, state or other
taxes for all fiscal periods are adequate. The Federal income tax liabilities of Obligors have been finally determined (whether
by reason of completed audits or the statute of limitations having run) for all fiscal years up to and including the fiscal year

course of business), in each case free and clear of Liens prohibited by this Agreement. All leases that individually or in the
aggregate are Material are valid and subsisting and are in full force and effect in all material respects.

patent, copyright, proprietary software, service mark, trademark, trade name or other right owned by any other Person.

reasonably be expected to result in a Material Adverse Effect. None of the Obligors nor any ERISA Affiliate has incurred any liability
pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined
in section 3 of ERISA), and no event, transaction or condition has occurred or exists that would reasonably be expected to
result in the incurrence of any such liability by any Obligor or any ERISA Affiliate, or in the imposition of any Lien on any of
the rights, properties or assets of any Obligor or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA
or to such penalty or excise tax provisions or to section 401(a)(29) or 412 of the Code or section 4068 of ERISA, other than

(c)          None
of the Obligors and their ERISA Affiliates have incurred withdrawal liabilities (and are not subject to contingent withdrawal liabilities)
under section 4201 or 4204 of ERISA in respect of Multi-employer Plans that individually or in the aggregate are Material.

 

(d)          The
expected post-retirement benefit obligation (determined as of the last day of the Company’s most recently ended fiscal year
in accordance with Financial Accounting Standards Board Statement No. 106, without regard to liabilities attributable to continuation
coverage mandated by section 4980B of the Code) of the Company and its Subsidiaries is not Material.

 

(e)          The
execution and delivery of this Agreement and the issuance and sale of the Series 2008A Notes hereunder will not constitute any
transaction that is subject to the prohibitions of section 406 of ERISA or in connection with which a tax would be imposed
pursuant to section 4975(c)(1)(A)-(D) of the Code. The representation by the Obligors to each Purchaser in the first sentence
of this Section 5.12(e) is made in reliance upon and subject to the accuracy of such Purchaser’s representation in Section

from, or otherwise approached or negotiated in respect thereof with, any person other than the Purchasers and not more than 40
other Institutional Investors, each of which has been offered the Series 2008A Notes at a private sale for investment. None of
the Obligors nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the

securities or blue sky laws of any applicable jurisdiction.

 

Section 5.14.         Use
of Proceeds; Margin Regulations. The Obligors will apply the proceeds of the sale of the Series 2008A Notes to refinance existing
Indebtedness and general corporate purposes. No part of the proceeds from the sale of the Series 2008A Notes hereunder will be
used, directly or indirectly, for the purpose of buying or carrying any margin stock within the meaning of Regulation U of
the Board of Governors of the Federal Reserve System (12 CFR 221), or for the purpose of buying or carrying or trading in
any securities under such circumstances as to involve any Obligor in a violation of Regulation X of said Board (12 CFR
224) or to involve any broker or dealer in a violation of Regulation T of said Board (12 CFR 220). Margin stock does
not constitute more than 5% of the value of the consolidated assets of the Company and its Subsidiaries and none of the Obligors
has any present intention that margin stock will constitute more than 5% of the value of such assets. As used in this Section,
the terms “margin stock” and “purpose of buying or carrying” shall have the meanings assigned to them in
said Regulation U.

 

Section 5.15.         Existing
Indebtedness; Future Liens (a) Except as described therein, Schedule 5.15 sets forth a complete and correct list of all
outstanding Indebtedness of the Obligors and their Subsidiaries as of May 31, 2008 (including a description of the obligors and
obligees, principal amount outstanding and collateral therefor, if any, and Guaranty thereof, if any), since which date there has
been no Material change in the amounts, interest rates, sinking funds, installment payments or maturities of the Indebtedness of
the Obligors. None of the Obligors is in default, and no waiver of default is currently in effect, in the payment of any principal
or interest on any Indebtedness of any Obligor, and no event or condition exists with respect to any Indebtedness of any Obligor,

Section
6.          Representations of the Purchasers.

 

Section 6.1.          Purchase
for Investment. (a) Each Purchaser severally represents that it is purchasing the Notes (i) for its own account or (ii) for
one or more separate accounts owned by such Purchaser or for the account of one or more pension or trust funds that are “accredited
investors” (as defined in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act), in each case for which
it is exercising investment discretion in managing investments of such pension or trust funds, in the case of each of clauses (i)
and (ii), for investment and not with a view to the distribution thereof, provided that the disposition of such Purchaser’s
property shall at all times be within such Purchaser’s control. Such Purchaser is a Qualified Institutional Buyer. Each Purchaser
(and each such pension, trust fund or other Person) understands that the Notes have not been registered under the Securities Act
and may be resold only if registered pursuant to the provisions of the Securities Act or if an exemption from registration is available,
except under circumstances where neither such registration nor such an exemption is required by law, and that the Company is not
required to register the Notes. Each Purchaser has carefully reviewed the Memorandum and is thoroughly familiar with the existing
and proposed business, operations, management, properties and financial condition of the Obligors as so described in the Memorandum.
Each Purchaser further represents that it (and each such pension, trust fund or other Person) has had the opportunity to ask questions
of the Company and received answers concerning the terms and conditions of the sale of the Notes. Each Purchaser’s (and each
such pension’s, trust fund’s or other Person’s) financial position is such that it can afford to bear the economic
risk of holding the Notes. Each Purchaser (and each such pension, trust fund or other Person) can afford to suffer the complete
loss of its investment in the Notes. Each Purchaser’s (and each such other Person’s) knowledge and experience in financial
and business matters (or the knowledge and experience of such Purchaser’s or such other Person’s investment advisor)
is such that it (or such investment advisor) is capable of evaluating the risks of the investment in the Notes. Each Purchaser
acknowledges that no representations, express or implied, have been or are being made with respect to the Obligors, the Notes or
otherwise, other than those expressly set forth herein or contemplated hereby.

 

(b)          Each
Purchaser agrees to the imprinting of a legend on the Notes to the following effect:

 

    		-12-	 

    	Waste Connections, Inc.	Note Purchase Agreement

    

 

“THIS NOTE HAS NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933 OR UNDER THE SECURITIES LAWS OF ANY STATE. NO TRANSFER, SALE OR OTHER DISPOSITION OF THIS NOTE
MAY BE MADE UNLESS A REGISTRATION STATEMENT WITH RESPECT TO THIS NOTE HAS BECOME EFFECTIVE UNDER SUCH ACT, AND SUCH REGISTRATION
OR QUALIFICATION AS MAY BE NECESSARY UNDER THE SECURITIES LAWS OF ANY STATE HAS BECOME EFFECTIVE, OR AN EXEMPTION FROM SUCH REGISTRATIONS
AND/OR QUALIFICATIONS IS AVAILABLE UNDER SUCH ACT AND SUCH LAWS. EACH TRANSFEREE OF THIS NOTE, BY ACCEPTANCE OF THIS NOTE REGISTERED
IN ITS NAME (OR THE NAME OF ITS NOMINEE), WILL BE DEEMED TO HAVE MADE CERTAIN REPRESENTATIONS SET FORTH IN THE AGREEMENT PURSUANT
TO WHICH THIS NOTE WAS ISSUED.”

 

Section 6.2.          Source
of Funds. Each Purchaser severally represents that at least one of the following statements is an accurate representation as
to each source of funds (a “Source”) to be used by such Purchaser to pay the purchase price of the Series 2008A
Notes to be purchased by it hereunder:

 

(a)          the
Source is an “insurance company general account” (as the term is defined in the United States Department of Labor’s
Prohibited Transaction Exemption (“PTE”) 95-60) in respect of which the reserves and liabilities (as defined
by the annual statement for life insurance companies approved by the National Association of Insurance Commissioners (the “NAIC
Annual Statement”)) for the general account contract(s) held by or on behalf of any employee benefit plan together with
the amount of the reserves and liabilities for the general account contract(s) held by or on behalf of any other employee benefit
plans maintained by the same employer (or affiliate thereof as defined in PTE 95-60) or by the same employee organization in the
general account do not exceed 10% of the total reserves and liabilities of the general account (exclusive of separate account liabilities)
plus surplus as set forth in the NAIC Annual Statement filed with such Purchaser’s state of domicile, and the purchase is
not part of an agreement, arrangement or understanding designed to benefit a “party in interest” (as that term is defined
in ERISA section 3(14)) within the meaning of PTE 95-60; or

 

(b)          the
Source is a separate account that is maintained solely in connection with such Purchaser’s fixed contractual obligations
under which the amounts payable, or credited, to any employee benefit plan (or its related trust) that has any interest in such
separate account (or to any participant or beneficiary of such plan (including any annuitant)) are not affected in any manner by
the investment performance of the separate account and the Purchaser’s fixed contractual obligations otherwise meet the requirements
for a “Guaranteed Benefit Policy” as defined in ERISA section 401(b)(2); or

 

(c)          the
Source is either (i) an insurance company pooled separate account, within the meaning of PTE 90-1 or (ii) a bank collective investment
fund, within the meaning of the PTE 91-38, and no employee benefit plan or group of plans maintained by the same employer or employee
organization beneficially owns more than 10% of all assets allocated to such pooled separate account or collective investment fund
, and the insurance company or bank agrees to maintain records and make such records available as required under PTE 90-1 Part
III(b) and (c) or PTE 91-38 Part III(b) and (c); or

(d)          the
Source constitutes assets of an “investment fund” (within the meaning of Part V of PTE 84-14 (the “QPAM Exemption”))
managed by a “qualified professional asset manager” or “QPAM” (within the meaning of Part V of the QPAM
Exemption), no employee benefit plan’s assets that are included in such investment fund, when combined with the assets of
all other employee benefit plans established or maintained by the same employer or by an affiliate (within the meaning of Section
V(c)(1) of the QPAM Exemption) of such employer or by the same employee organization and managed by such QPAM, exceed 20% of the
total client assets managed by such QPAM, the conditions of Part I(b)(1), (c) and (g) of the QPAM Exemption are satisfied, as of
the last day of its most recent calendar quarter, the QPAM does not own a 10% or more interest in the Company and no person controlling
or controlled by the QPAM (applying the definition of “control” in Section V(e) of the QPAM Exemption) owns a
20% or more interest in the Company (or less than 20% but greater than 10%, if such person exercises control over the management
or policies of the Company by reason of its ownership interest) and (i) the identity of such QPAM and (ii) the names of all employee
benefit plans that own a 10% or greater interest in such investment fund have been disclosed to the Company in writing pursuant
to this clause (d); or

 

(e)          the
Source constitutes assets of a “plan(s)” (within the meaning of Section IV of PTE 96-23 (the “INHAM Exemption”))
managed by an “in-house asset manager” or “INHAM” (within the meaning of Part IV of the INHAM Exemption),
the conditions of Part I(a), (b)(1), (c), (g) and (h) of the INHAM Exemption are satisfied, neither the INHAM nor a person controlling
or controlled by the INHAM (applying the definition of “control” in Section IV(d) of the INHAM Exemption) owns a 5%
or more interest in the Company and (i) the identity of such INHAM and (ii) the name(s) of the employee benefit plan(s) whose assets
constitute the Source have been disclosed to the Company in writing pursuant to this clause (e); or

 

(f)          the
Source is a governmental plan and there is no applicable law that prohibits or limits that plan’s purchase of Notes pursuant
to this Agreement; or

 

(g)          the
Source is one or more employee benefit plans, or a separate account or trust fund comprised of one or more employee benefit plans,
each of which has been identified to the Company in writing pursuant to this clause (g); or

 

(h)          the
Source does not include assets of any employee benefit plan or Individual Retirement Account, other than a plan exempt from the
coverage of ERISA.

 

As used in this Section 6.2, the terms
“employee benefit plan,” “governmental plan,” and “separate account” shall have the respective
meanings assigned to such terms in section 3 of ERISA.

LIBOR Breakage Amount (unless the date of prepayment is an Interest Payment Date) determined for the prepayment date with respect
to such principal amount. The Company will give each holder of Notes written notice of each optional prepayment under this Section 8.2
not less than ten days and not more than 60 days prior to the date fixed for such prepayment unless the Company and the Required
Holders agree to another time period pursuant to Section 17. Each such notice shall specify such date (which shall be a Business
Day), the aggregate principal amount of the Notes to be prepaid on such date, the principal amount of each Note held by such holder
to be prepaid (determined in accordance with Section 8.3), and the interest to be paid on the prepayment date with respect
to such principal amount being prepaid, and shall be accompanied by a certificate of a Senior Financial Officer as to the estimated
Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment),
setting forth the details of such computation. Two Business Days prior to such prepayment, the Obligors shall deliver to each holder
of Notes a certificate of a Senior Financial Officer specifying the calculation of such Make-Whole Amount as of the specified prepayment
date.

Section 8.3.          Allocation
of Partial Prepayments. In the case of each partial prepayment of the Notes pursuant to Section 8.2, the principal amount
of the Notes to be prepaid shall be allocated among all of the Notes at the time outstanding in proportion, as nearly as practicable,
to the respective unpaid principal amounts thereof not theretofore called for prepayment. All regularly scheduled partial prepayments
made with respect to any series of Additional Notes pursuant to any Supplement shall be allocated as provided therein.

 

Section 8.4.          Maturity;
Surrender, Etc. In the case of each prepayment of Notes pursuant to this Section 8, the principal amount of each Note to be
prepaid shall mature and become due and payable on the date fixed for such prepayment (which shall be a Business Day), together
with interest on such principal amount accrued to such date and the applicable Make-Whole Amount, if any. From and after such date,
unless the Obligors shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole
Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be
surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal
amount of any Note.

 

Section 8.5.          Purchase
of Notes. The Obligors will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly
or indirectly, any of the outstanding Notes except (i) upon the payment or prepayment of the Notes in accordance with the terms
of this Agreement (including any Supplement hereto) and the Notes, and (ii) pursuant to a written offer to purchase any outstanding
Notes made by the Company or an Affiliate pro rata to the holders of the Notes upon the same terms and conditions. The Obligors
will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment or prepayment of Notes pursuant to any provision
of this Agreement and no Notes may be issued in substitution or exchange for any such Notes.

 

Section 8.6.          Make-Whole
Amount for the Series 2008A Notes. “Make-Whole Amount” means, with respect to any Series 2008A Note, an amount
equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of
such Series 2008A Note minus the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than
zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings:

 

“Called
Principal” means, with respect to any Series 2008A Note, the principal of such Series 2008A Note that is to be prepaid
pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the
context requires.

 

“Discounted
Value” means, with respect to the Called Principal of any Series 2008A Note, the amount obtained by discounting all Remaining
Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with
respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same
periodic basis as that on which interest on such Series 2008A Notes is payable) equal to the Reinvestment Yield with respect to
such Called Principal.

 

    		-21-	 

    	Waste Connections, Inc.	Note Purchase Agreement

    

 

“Reinvestment
Yield” means, with respect to the Called Principal of any Series 2008A Note, 0.50% over the yield to maturity implied
by (i) the yields reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date
with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace
Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on the run U.S. Treasury securities having
a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields
are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation),
the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of
the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release
H.15(519) (or any comparable successor publication) for actively traded U.S. Treasury securities having a constant maturity equal
to the Remaining Average Life of such Called Principal as of such Settlement Date.

 

In the case
of each determination under clause (i) or clause (ii), as the case may be, of the preceding paragraph, such implied yield will
be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with
accepted financial practice and (b) interpolating linearly between (1) the applicable U.S. Treasury security with the
maturity closest to and greater than such Remaining Average Life and (2) the applicable U.S. Treasury security with the maturity
closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as
appears in the interest rate of the applicable Series 2008A Note.

 

“Remaining
Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth
year) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the
principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years (calculated
to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled
due date of such Remaining Scheduled Payment.

 

“Remaining
Scheduled Payments” means, with respect to the Called Principal of any Series 2008A Note, all payments of such Called
Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment
of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date
on which interest payments are due to be made under the terms of the Series 2008A Notes, then the amount of the next succeeding
scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on
such Settlement Date pursuant to Section 8.2 or 12.1.

 

    		-22-

“Settlement
Date” means, with respect to the Called Principal of any Series 2008A Note, the date on which such Called Principal is
to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1,
as the context requires.

 

Section 8.7.          Change
in Control. (a) Notice of Change in Control or Control Event.  The Company will, within 15 Business Days after
any Responsible Officer has knowledge of the occurrence of any Change in Control or Control Event, give written notice of such
Change in Control or Control Event to each holder of Notes unless notice in respect of such Change in Control (or the Change
in Control contemplated by such Control Event) shall have been given pursuant to subparagraph (b) of this Section 8.7. If
a Change in Control has occurred, such notice shall contain and constitute an offer to prepay Notes of each Series as described
in subparagraph (c) of this Section 8.7 and shall be accompanied by the certificate described in subparagraph (g) of this
Section 8.7.

 

(b)          Condition
to Obligor Action. The Company will not take any action, directly or indirectly, that consummates or finalizes a Change in
Control unless (i) at least 15 Business Days prior to such action it shall have given to each holder of Notes written
notice containing and constituting an offer to prepay Notes as described in subparagraph (c) of this Section 8.7, accompanied
by the certificate described in subparagraph (g) of this Section 8.7, and (ii) contemporaneously with such action, it
prepays all Notes required to be prepaid in accordance with this Section 8.7.

 

(c)          Offer
to Prepay Notes. The offer to prepay Notes contemplated by subparagraphs (a) and (b) of this Section 8.7 shall be an
offer to prepay, in accordance with and subject to this Section 8.7, all, but not less than all, the Notes held by each holder
(in this case only, “holder” in respect of any Note registered in the name of a nominee for a disclosed beneficial
owner shall mean such beneficial owner) on a date specified in such offer (the “Proposed Prepayment Date”).
If such Proposed Prepayment Date is in connection with an offer contemplated by subparagraph (a) of this Section 8.7,
such date shall be not less than 20 days and not more than 30 days after the date of such offer (if the Proposed Prepayment
Date shall not be specified in such offer, the Proposed Prepayment Date shall be the 20th day after the date of such offer).

 

(d)          Acceptance;
Rejection. A holder of Notes may accept or reject the offer to prepay made pursuant to this Section 8.7 by causing a
notice of such acceptance or rejection to be delivered to the Obligors at least 5 Business Days prior to the Proposed Prepayment
Date. A failure by a holder of Notes to respond to an offer to prepay made pursuant to this Section 8.7 shall be deemed to
constitute a rejection of such offer by such holder.

 

(e)          Prepayment.
Prepayment of the Notes to be prepaid pursuant to this Section 8.7 shall be at 100% of the principal amount of such Notes,
together with interest on such Notes accrued to the date of prepayment plus the LIBOR Breakage Amount (unless the date of prepayment
is an Interest Payment Date). The prepayment shall be made on the Proposed Prepayment Date except as provided in subparagraph
(f) of this Section 8.7.

 

    		-23-	 

    	Waste Connections, Inc.	Note Purchase Agreement

    

 

(f)          Deferral
Pending Change in Control. The obligation of the Obligors to prepay Notes pursuant to the offers required by subparagraph (b)
and accepted in accordance with subparagraph (d) of this Section 8.7 is subject to the occurrence of the Change in Control
in respect of which such offers and acceptances shall have been made. In the event that such Change in Control does not occur
on the Proposed Prepayment Date in respect thereof, the prepayment shall be deferred until and shall be made on the date on which
such Change in Control occurs. The Obligors shall keep each holder of Notes reasonably and timely informed of (i) any such
deferral of the date of prepayment, (ii) the date on which such Change in Control and the prepayment are expected to occur,
and (iii) any determination by the Obligors that efforts to effect such Change in Control have ceased or been abandoned (in
which case the offers and acceptances made pursuant to this Section 8.7 in respect of such Change in Control shall be deemed
rescinded).

 

(g)          Officer’s
Certificate.  Each offer to prepay the Notes pursuant to this Section 8.7 shall be accompanied by a certificate, executed
by a Senior Financial Officer of the Obligors and dated the date of such offer, specifying: (i) the Proposed Prepayment Date;
(ii) that such offer is made pursuant to this Section 8.7; (iii) the principal amount of each Note offered to be
prepaid; (iv) the interest that would be due on each Note offered to be prepaid, accrued to the Proposed Prepayment Date;
(v) that the conditions of this Section 8.7 have been fulfilled; and (vi) in reasonable detail, the nature and
date or proposed date of the Change in Control.

 

(h)          Effect
on Required Payments. The amount of each payment of the principal of the Notes made pursuant to this Section 8.7 shall
be applied against and reduce each of the then remaining principal payments, if any, due pursuant to any Supplement by a percentage
equal to the aggregate principal amount of the Notes so paid divided by the aggregate principal amount of the Notes outstanding
immediately prior to such payment.

 

(i)          “Control
Event” Defined. “Control Event” means:

 

(i)          the
execution by the Company or any of its Subsidiaries or Affiliates of any agreement with respect to any proposed transaction or
event or series of transactions or events which, individually or in the aggregate, would result in a Change in Control,

 

(ii)         the
execution of any written agreement which, when fully performed by the parties thereto, would result in a Change in Control, or

 

(iii)        the
acceptance by the requisite number of holders of any written offer by any person (as such term is used in section 13(d) and section
14(d)(2) of the Exchange Act as in effect on the date of the Closing) or related persons constituting a group (as such term is
used in Rule 13d-5 under the Exchange Act as in effect on the date of the Closing) to the holders of the common stock of the Company,
which would result in a Change in Control.

Section
9.          Affirmative Covenants. 

 

The Company covenants
that so long as any of the Notes are outstanding:

 

Section 9.1.          Punctual
Payment. The Company will duly and punctually pay or cause to be paid the principal and interest on the Notes, fees and other
amounts provided for in this Agreement and the Notes, all in accordance with the terms of this Agreement and the Notes.

 

Section 9.2.          Records
and Accounts. The Company will, and will cause each of its Subsidiaries to (i) keep true and accurate records and books
of account in which full, true and correct entries will be made in accordance with generally accepted accounting principles, (ii) maintain
adequate accounts and reserves for all taxes (including income taxes), depreciation, depletion, obsolescence and amortization of
its properties, contingencies, and other reserves, and (iii) at all times engage an independent accounting firm of national
standing pursuant to the Bank Credit Agreement as the independent certified public accountants of the Company.

 

Section 9.3.          Legal
Existence and Conduct of Business. Except as otherwise permitted by Section 10.4, the Company will, and will cause each
of its Material Subsidiaries to, do or cause to be done all things necessary to preserve and keep in full force and effect its
legal existence, legal rights and franchises; effect and maintain its foreign qualifications, licensing, domestication or authorization
except as terminated by the Company’s or its Material Subsidiaries’ board of directors (or similar governing body)
in the exercise of its reasonable judgment and except where the failure of the Company and its Material Subsidiaries to remain
so qualified would not have a Material Adverse Effect; and shall not become obligated under any contract or binding arrangement
which, at the time it was entered into would have a Material Adverse Effect. The Company will, and will cause its Subsidiaries
to, continue to engage primarily in the businesses conducted by it on the date of the Assumption Agreement and in related businesses,
except to the extent otherwise permitted under Sections 10.3 and 10.4.

 

Section 9.4.          Maintenance
of Properties. The Company will, and will cause each of its Material Subsidiaries to, cause all material properties used or
useful in the conduct of their businesses to be maintained and kept in good condition, repair and working order and supplied with
all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof,
all as in the judgment of the Company and its Material Subsidiaries may be necessary so that the businesses carried on in connection
therewith may be properly and advantageously conducted at all times;  provided, however, that nothing in this section shall
prevent the Company or any of its Subsidiaries from discontinuing the operation and maintenance of any of their properties if such
discontinuance is, in the judgment of the Company or such Subsidiary, desirable in the conduct of their business and which does
not in the aggregate have a Material Adverse Effect.

Section 9.5.          Insurance.
The Company will, and will cause each of its Subsidiaries to, maintain with financially sound and reputable insurance companies,
funds or underwriters insurance of the kinds, covering the risks (other than risks arising out of or in any way connected with
personal liability of any officers and directors thereof) and in the relative proportionate amounts typically carried by reasonable
and prudent companies conducting businesses similar to that of the Company and its Subsidiaries. In addition, the Company and its
Subsidiaries will furnish from time to time, upon the request of the Required Holders, a summary of the insurance coverage, which
summary shall be in form and substance reasonably satisfactory to the Required Holders (it being understood that any such summary
of the insurance coverage delivered pursuant to the Bank Credit Agreement shall be deemed to be reasonably satisfactory to the
Required Holders) and, if requested by the Required Holders, will furnish to the Required Holders certificates evidencing such
insurance. If the agents under the Bank Credit Agreement require that any certificate evidencing liability insurance name the agents
as the certificate holder thereunder, the Company shall cause any such certificate to also name the holders as the certificate
holder thereunder. Notwithstanding the foregoing, the Company and its Subsidiaries shall be permitted to maintain self-insurance
programs to the extent permitted under the Bank Credit Agreement.

 

Section 9.6.          Taxes.
The Company will, and will cause each of its Subsidiaries to, duly pay and discharge, or cause to be paid and discharged, before
any Material penalty accrues thereon, all Taxes (other than Taxes which in the aggregate are not Material to the business or assets
of the Company or any Subsidiary on an individual basis or of the Company and its Subsidiaries on a consolidated basis) imposed
upon it and its real properties, sales and activities, or any Material part thereof, or upon the income or profits therefrom, as
well as all claims for labor, materials, or supplies, which if unpaid might by law become a Lien or charge upon any Material portion
of its property, unless such Lien is a Permitted Lien; provided, however, that any such Tax or claim need not be
paid if the validity or amount thereof shall currently be contested in good faith by appropriate proceedings and if the Company
or such Subsidiary shall have set aside on its books adequate reserves with respect thereto; and provided further,
that the Company or such Subsidiary will pay all such Taxes or claims forthwith upon the commencement of proceedings to foreclose
any Lien which may have attached as security therefor.

 

Section 9.7.          Compliance
with Laws, Contracts, Licenses and Permits; Maintenance of Material Licenses and Permits.  The Company will, and will cause
each of its Subsidiaries to (i) comply with the provisions of their Organization Documents, (ii) comply with the provisions
of all agreements and instruments by which they or any of their properties may be bound; and (iii) comply with all applicable
laws (including Environmental Laws and Environmental Permits) except, in the case of subsections (i) (solely for non-compliance
with the provisions of its Organization Documents by a Person other than the Company or a Material Subsidiary), (ii) and (iii),
where noncompliance with such Organization Documents, applicable agreements, instruments and laws would not have a Material Adverse
Effect. If at any time while any Note is outstanding, any authorization, consent, approval, permit or license from any Governmental
Authority shall become necessary or required in order that the Company or any Material Subsidiary may fulfill any of their obligations
hereunder, the Company will immediately take or cause to be taken all reasonable steps within the power of the Company or such
Material Subsidiary to obtain such authorization, consent, approval, permit or license and furnish the Lenders with evidence thereof.

Section 9.8.          Environmental
Indemnification.  The Company, on its own behalf and on behalf of its Subsidiaries, jointly and severally covenant and agree
that it will indemnify and hold the holders harmless from and against any and all claims, expense, damage, loss or liability incurred
by the holders (including all costs of legal representation) relating to (a) [reserved]; (b) any Release or threatened
Release of Hazardous Materials on the Real Estate; (c) [reserved]; (d) any violation of any Environmental Laws with
respect to conditions at the Real Estate or the operations conducted thereon; (e) the investigation or remediation of offsite
locations at which the Company, any of its Subsidiaries, or its predecessors are alleged to have directly or indirectly disposed
of Hazardous Materials; or (f) any Environmental Liability related in any way to the Company or any of its Subsidiaries. It
is expressly acknowledged by the Company and its Subsidiaries that this covenant of indemnification shall include claims, expense,
damage, loss or liability incurred by the holders based upon the holders’ negligence (but not gross negligence or willful
misconduct, in each case as determined by a court of competent jurisdiction by a final and nonappealable judgment), and this covenant
shall survive any foreclosure or any modification, release or discharge of the Notes and this Agreement or the payment of the Notes
and shall inure to the benefit of the holders and their successors and permitted assigns.

 

Section 9.9.          Additional
Notices.  The Company will promptly notify the holders in writing of any material change by the Company or any Subsidiary in
accounting policies, financial reporting practices (subject to Section 10.12) or attestation reports concerning internal controls
pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, as amended and in effect from time to time.

 

Section 9.10.         Designation
of Material Subsidiaries.  Concurrently with the delivery of a Compliance Certificate, the Company shall from time to time
designate one or more Subsidiaries as a Material Subsidiary in order to remain in compliance with the Material Subsidiary conditions,
as set forth in the definition thereof. Upon such designation, Schedule 9.10 shall be deemed amended to include such new designated
Material Subsidiaries.

 

Section 9.11.         Canadian

Plan administered by the Company or any of its Canadian Subsidiaries, the Company will, and will cause each Canadian Subsidiary
to, comply with and perform in all material respects all of their material obligations under and in respect of such Canadian Pension
Plan or Canadian Benefit Plan, including under any funding agreements and all applicable laws and regulations (including any funding,
investment and administration obligations).

 

(b)          The
Company will, and will cause each of its Canadian Subsidiaries to, withhold, pay or remit all Material employer and employee payments,
contributions and premiums required to be remitted, paid to or in respect of each Canadian Pension Plan and Canadian Benefit Plan
in a timely fashion in accordance with the terms thereof, any funding agreements and all applicable laws.

(c)          The
Company will, and will cause each Canadian Subsidiary to, deliver to the holders (i) promptly after receipt thereof, a copy
of any material claim, direction, order, notice, ruling or opinion that the Company or any Canadian Subsidiary may receive from
any applicable Canadian Governmental Authority or other claimant, except for regular claims for benefits with respect to any Canadian
Pension Plan or Canadian Benefit Plan that can reasonably be expected to give rise to a liability in excess of $10,000,000 (or
its equivalent in the relevant currency); (ii) notification within 30 days of receipt of an actuarial report or accounting
disclosure report that discloses any increases having a cost to the Company or any Canadian Subsidiary in excess of $10,000,000
(or its equivalent in the relevant currency) in the aggregate, in respect of any existing Canadian Pension Plan or Canadian Benefit
Plan, and (iii) subject to Section 10.16, notification within thirty (30) days of the establishment of any new Canadian
Pension Plan that has a “defined benefit provision” as that term is defined in the ITA, or the commencement of contributions
to any such plan to which the Company or any Canadian Subsidiary participating thereof was not previously contributing that can
be expected to give rise to an annual liability in excess of $10,000,000 (or its equivalent in the relevant currency).

 

(d)          The
Company will, and will cause each Canadian Subsidiary to, withhold, pay or remit all material employer and employee contributions
and premiums required to be remitted, paid to or in respect of the Canadian Pension Plan or the Quebec Pension Plan, or any plan
required under Canadian federal, provincial or territorial health, workers’ compensation, and employment insurance legislation
in compliance with applicable laws and regulations.

 

Section 9.12.         Notes
to Rank Pari Passu. The Notes and all other obligations under this Agreement of the Company are and at all times shall remain
direct and unsecured obligations of the Company ranking pari passu as against the assets of the Company with all other Notes
from time to time issued and outstanding hereunder without any preference among themselves, and at least pari passu with
all Indebtedness outstanding under any Material Credit Facility and all other present and future unsecured Indebtedness (actual
or contingent) of the Company which is not expressed to be subordinate or junior in rank to any other unsecured Indebtedness of
the Company, except to the extent that any Material Credit Facility becomes secured, then the Notes shall also become secured and
shall rank at least pari passu therewith. The Company will ensure that the payment obligations of any Subsidiary Guarantor
under its Subsidiary Guaranty will at all times rank at least pari passu, without preference or priority, with all other
unsecured and unsubordinated Indebtedness of such Subsidiary Guarantor.

 

Section 9.13.         Subsidiary
Guarantors.  (a) The Company will cause each of its Subsidiaries that guarantees or otherwise becomes liable at any time, whether
as a borrower or an additional or co-borrower or otherwise, for or in respect of any Indebtedness under any Material Credit Facility
to concurrently therewith:

 

(i)          enter
into an agreement in form and substance reasonably satisfactory to the Required Holders providing for the guaranty by such Subsidiary,
on a joint and several basis with all other such Subsidiary Guarantors, of (x) the prompt payment in full when due of all
amounts payable by the Company pursuant to the Notes (whether for principal, interest, Make-Whole Amount or otherwise) and this
Agreement, including all indemnities, fees and expenses payable by the Company thereunder and (y) the performance, observance
and discharge by the Company of each and every covenant, agreement, and duties required pursuant to the Notes or this Agreement
to be performed, observed or discharged by it (a “Subsidiary Guaranty”); and

    	Waste Connections, Inc.	Note Purchase Agreement

    

 

(ii)         deliver
the following to each holder of a Note:

 

(A)         an
executed counterpart of such Subsidiary Guaranty;

 

(B)         a
certificate signed by an authorized responsible officer of such Subsidiary Guarantor containing representations and warranties
on behalf of such Subsidiary Guarantor to the same effect, mutatis mutandis, as those contained in Sections 5.1, 5.2, 5.6
(consistent with the supplemental representations made by the Parent in the Assumption Agreement) and 5.7 of this Agreement (but
with respect to such Subsidiary and such Subsidiary Guaranty);

 

(C)         all
documents as may be reasonably and customarily requested by the Required Holders to evidence the due organization, continuing existence
and, where applicable, good standing of such Subsidiary Guarantor and the due authorization by all requisite action on the part
of such Subsidiary Guarantor of the execution and delivery of such Subsidiary Guaranty and the performance by such Subsidiary Guarantor
of its obligations thereunder; and

 

(D)         an
opinion of counsel reasonably satisfactory to the Required Holders covering such customary matters relating to such Subsidiary
Guarantor and such Subsidiary Guaranty as the Required Holders may reasonably request.

 

(b)          At
the election of the Company and by written notice to each holder of Notes, any Subsidiary Guarantor may be discharged from all
of its obligations and liabilities under its Subsidiary Guaranty and shall be automatically released from its obligations thereunder
without the need for the execution and delivery of any other document by the holders, provided that (i) if such Subsidiary
Guarantor is a guarantor or is otherwise liable for or in respect of any Material Credit Facility, then such Subsidiary Guarantor
has been released and discharged (or will be released and discharged concurrently with the release of such Subsidiary Guarantor
under its Subsidiary Guaranty) under such Material Credit Facility, (ii) at the time of, and after giving effect to, such
release and discharge, no Default or Event of Default shall be existing, (iii) no amount is then due and payable under such
Subsidiary Guaranty, (iv) if in connection with such Subsidiary Guarantor being released and discharged under any Material
Credit Facility, any fee or other form of consideration is given to any holder of Indebtedness, in its capacity as a holder of
such Indebtedness, under such Material Credit Facility for such release, other than the repayment of all or a portion of such Indebtedness,
the holders of the Notes shall receive equivalent consideration substantially concurrently therewith (provided that, for
the avoidance of doubt, this condition shall not apply to customary and usual fees paid in connection with the termination and
replacement of a Material Credit Facility and out-of-pocket expenses, including attorneys’ fees, incurred in connection therewith),
and (v) each holder shall have received a certificate of a Responsible Officer certifying as to the matters set forth in clauses
(i) through (iv). In the event of any such release, for purposes of Section 10.1(k), all Indebtedness of such Subsidiary shall
be deemed to have been incurred concurrently with such release.

 

(c)          The
Company shall at all times, directly or indirectly, own 100% of the equity interest of each Subsidiary Guarantor.

Section
12.         Remedies on Default, Etc.

 

Section 12.1.          Acceleration.
(a) If an Event of Default with respect to any Obligor described in Section 11(g) or (h) (other than an Event of Default described
in clause (i) of Section 11(g) or described in clause (vi) of Section 11(g) by virtue of the fact that such
clause encompasses clause (i) of Section 11(g)) has occurred, all the Notes then outstanding shall automatically become
immediately due and payable.

 

(b)          If
any other Event of Default has occurred and is continuing, the Required Holders may at any time at their option, by notice or notices
to any Obligor, declare all the Notes then outstanding to be immediately due and payable.

 

(c)          If
any Event of Default described in Section 11(a) or (b) has occurred and is continuing, any holder or holders of Notes at the
time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the Company,
declare all the Notes held by it or them to be immediately due and payable.

 

    		-44-	 

    	Waste Connections, Inc.	Note Purchase Agreement

    

 

Upon any Notes becoming
due and payable under this Section 12.1, whether automatically or by declaration, such Notes will forthwith mature and the
entire unpaid principal amount of such Notes, plus (x) all accrued and unpaid interest thereon (including, but not limited to,
interest accrued thereon at the Default Rate) and (y) the Make-Whole Amount and LIBOR Breakage Amount determined in respect of
such principal amount (to the full extent permitted by applicable law), shall all be immediately due and payable, in each and every
case without presentment, demand, protest or further notice, all of which are hereby waived. Each Obligor acknowledges, and the
parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by any
Obligor (except as herein specifically provided for) and that the provision for payment of a Make-Whole Amount by the Obligors
in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation
for the deprivation of such right under such circumstances.

 

Section 12.2.          Other
Remedies. If any Default or Event of Default has occurred and is continuing, and irrespective of whether any Notes have become
or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed
to protect and enforce the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for
the specific performance of any agreement contained herein or in any Note, or for an injunction against a violation of any of the
terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise.

 

Section 12.3.          Rescission.
At any time after any Notes have been declared due and payable pursuant to Section 12.1(b) or (c), the Required Holders by
written notice to any Obligor, may rescind and annul any such declaration and its consequences if (a) the Obligors have paid
all overdue interest on the Notes, all principal of and Make-Whole Amount, if any, and LIBOR Breakage Amount, if any, on any Notes,
that are due and payable and are unpaid other than by reason of such declaration, and all interest on such overdue principal and
Make-Whole Amount, if any, and LIBOR Breakage Amount, if any, and (to the extent permitted by applicable law) any overdue interest
in respect of the Notes, at the Default Rate, (b) none of the Obligors nor any other Person shall have paid any amounts which
have become due solely by reason of such declaration, (c) all Events of Default and Defaults, other than non-payment of amounts
that have become due solely by reason of such declaration, have been cured or have been waived pursuant to Section 17, and
(d) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to the Notes. No rescission
and annulment under this Section 12.3 will extend to or affect any subsequent Event of Default or Default or impair any right
consequent thereon.

 

Section 12.4.          No
Waivers or Election of Remedies, Expenses, Etc. No course of dealing and no delay on the part of any holder of any Note in
exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such holder’s rights, powers
or remedies. No right, power or remedy conferred by this Agreement or by any Note upon any holder thereof shall be exclusive of
any other right, power or remedy referred to herein or therein or now or hereafter available at law, in equity, by statute or otherwise.
Without limiting the obligations of the Obligors under Section 15, the Obligors will pay to the holder of each Note on demand
such further amount as shall be sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection
under this Section 12, including, without limitation, reasonable attorneys’ fees, expenses and disbursements.

interest owing to each holder of the Notes, each transfer thereof and the name and address (including e-mail address, if applicable)
of, and the principal amount and stated interest of the Notes owing to, each transferee of one or more Notes shall be registered
in such register. Prior to due presentment for registration of transfer, the Person in whose name any Note shall be registered
shall be deemed and treated as the owner and holder thereof for all purposes hereof, and the Company shall not be affected by any
notice or knowledge to the contrary. The Company shall (or shall cause its agent to) give to any holder of a Note that is an Institutional
Investor promptly upon request therefor, a complete and correct copy of the names and addresses of all registered holders of Notes.

payment by the relevant holder of sum sufficient to cover any tax or other governmental charge that may be imposed in connection
with such registration of transfer or exchange to a Person other than the Company or its Affiliates.

 

Section 13.2.          Transfer
and Exchange of Notes. Upon surrender of any Note to the Company at the address and to the attention of the designated officer

of transfer accompanied by a written instrument of transfer duly executed by the registered holder of such Note or such holder’s
attorney duly authorized in writing and accompanied by the relevant name, address and other information for notices of each transferee
of such Note or part thereof) within ten Business Days thereafter the Company shall execute and deliver, at the Company’s
expense (except as provided below), one or more new Notes of the same series (and of the same tranche if such series has multiple
tranches) as requested by the holder thereof in exchange therefor, in an aggregate principal amount equal to the unpaid principal
amount of the surrendered Note. Each such new Note shall be payable to such Person as such holder may request and shall be substantially
in the form of Exhibit 1 hereto or Exhibit 1 of the appropriate Supplement, as applicable. Each such new Note shall be
dated and bear interest from the date to which interest shall have been paid on the surrendered Note or dated the date of the surrendered
Note if no interest shall have been paid thereon. The Company may require payment of a sum sufficient to cover any stamp tax or
governmental charge imposed in respect of any such transfer of Notes. Notes shall not be transferred in denominations of less than
$100,000, provided that if necessary to enable the registration of transfer by a holder of its entire holding of Notes, one Note
may be in a denomination of less than $100,000. Any transferee, by its acceptance of a Note registered in its name (or the name
of its nominee), shall be deemed to have made the representations set forth in Section 6.1, Section 6.2 and Section 23(k),
and the Company shall not be obligated to register any Note in the name of any transferee who cannot make the representations set
forth in Section 6.1, Section 6.2 and Section 23(k) or with respect to any transfer that would result in a “prohibited
transaction” within the meaning of Section 406 of ERISA.

or is a nominee for, an original Purchaser or another holder of a Note with a minimum net worth of at least $50,000,000 or a Qualified
Institutional Buyer, such Person’s own unsecured agreement of indemnity shall be deemed to be satisfactory), or

 

(b)          in
the case of mutilation, upon surrender and cancellation thereof,

 

within ten Business Days thereafter the
Company at its own expense shall execute and deliver, in lieu thereof, a new Note of the same series (and of the same tranche if

of a bank or trust company in such jurisdiction.

 

Section 14.2.          Home
Office Payment. So long as any Purchaser or Additional Purchaser or such Purchaser’s nominee or such Additional Purchaser’s

the Company will pay all sums becoming due on such Note for principal, Make-Whole Amount or LIBOR Breakage Amount, if any, interest
and all other amounts becoming due hereunder by the method and at the address specified for such purpose below such Purchaser’s
name in Schedule A hereto, or, in the case of any Additional Purchaser’s Schedule A attached to any Supplement
pursuant to which such Additional Purchaser is a party, or by such other method or at such other address as such Purchaser or Additional
Purchaser shall have from time to time specified to the Company in writing for such purpose, without the presentation or surrender
of such Note or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably
promptly after payment or prepayment in full of any Note, such Purchaser or Additional Purchaser shall surrender such Note for
cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment
most recently designated by the Company pursuant to Section 14.1. Prior to any sale or other disposition of any Note held
by any Purchaser or Additional Purchaser or such Person’s nominee, such Person will, at its election, either endorse thereon

to Section 13.2. The Company will afford the benefits of this Section 14.2 to any Institutional Investor that is the
direct or indirect transferee of any Note purchased by a Purchaser under this Agreement and that has made the same agreement relating
to such Note as the Purchasers have made in this Section 14.2.

other holder of a Note harmless from, all claims in respect of any fees, costs or expenses, if any, of brokers and finders (other
than those, if any, retained by a Purchaser or an Additional Purchaser or other holder in connection with its purchase of the Notes).
If required by the NAIC, the Company shall obtain and maintain at its own cost and expense a Legal Entity Identifier (LEI). For
the avoidance of doubt, costs and expenses shall include any Registration Duty. This Section 15.1 shall not apply with respect
to Taxes other than any Taxes that represent losses, claims, damages or similar charges arising from any non-Tax claim.

therein and the payment of any Note, and may be relied upon by any subsequent holder of a Note, regardless of any investigation

Section
17.         Amendment and Waiver.

 

Section 17.1.          Requirements.
(a) This Agreement (including any Supplement) and the Notes may be amended, and the observance of any term hereof or of the
Notes may be waived (either retroactively or prospectively), with (and only with) the written consent of the Obligors and the Required
Holders, except that (i) no amendment or waiver of any of the provisions of Section 1, 2, 3, 4, 5, 6 or 21 hereof or
the corresponding provision of any Supplement, or any defined term (as it is used in any such Section or such corresponding provision
of any Supplement), will be effective as to any holder of Notes unless consented to by such holder of Notes in writing, and (ii) no
such amendment or waiver may, without the written consent of the holder of each Note at the time outstanding affected thereby,
(A) subject to the provisions of Section 12 relating to acceleration or rescission, change the amount or time of any
prepayment or payment of principal of, or reduce the rate or change the time of payment or method of computation of interest or

existence of a Default or Event of Default, no Obligor may be removed from its obligations under this Agreement and the Notes and
become an Excluded Subsidiary without the written consent of the Obligors and each holder of Notes.

    	Waste Connections, Inc.	Note Purchase Agreement

    

 

(b)          Supplements.
Notwithstanding anything to the contrary contained herein, the Obligors may enter into any Supplement providing for the issuance
of one or more series of Additional Notes consistent with Sections 1.2 and 4.12 hereof without obtaining the consent of any holder
of any other series of Notes.

 

(c)          Consent
in Contemplation of Transfer. Any consent made pursuant to this Section 17 by a holder of Notes that has transferred or
has agreed to transfer its Notes to the Company, any Subsidiary or any Affiliate of the Company and has provided or has agreed
to provide such written consent as a condition to such transfer shall be void and of no force or effect except solely as to such
holder, and any amendments effected or waivers granted or to be effected or granted that would not have been or would not be so
effected or granted but for such consent (and the consents of all other holders of Notes that were acquired under the same or similar
conditions) shall be void and of no force or effect except solely as to such holder.

 

Section 17.2.          Solicitation
of Holders of Notes.

 

(a)          Solicitation.
The Obligors will provide each holder of the Notes (irrespective of the amount of Notes then owned by it) with sufficient information,
sufficiently far in advance of the date a decision is required, to enable such holder to make an informed and considered decision
with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof, any Supplement or of the
Notes. The Obligors will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to
the provisions of this Section 17 to each holder of outstanding Notes promptly following the date on which it is executed and delivered
by, or receives the consent or approval of, the requisite holders of Notes.

 

(b)          Payment.
None of the Obligors will directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional
interest, fee or otherwise, or grant any security or provide other credit support, to any holder of Notes as consideration for
or as an inducement to the entering into by any holder of Notes of any waiver or amendment of any of the terms and provisions hereof
or any Supplement unless such remuneration is concurrently paid, or security is concurrently granted or other credit support concurrently
provided, on the same terms, ratably to each holder of Notes then outstanding even if such holder did not consent to such waiver
or amendment.

Section 17.3.          Binding
Effect, Etc. Any amendment or waiver consented to as provided in this Section 17 applies equally to all holders of Notes and
is binding upon them and upon each future holder of any Note and upon the Obligors without regard to whether such Note has been
marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement,
Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between
any Obligor and the holder of any Note nor any delay in exercising any rights hereunder or under any Note shall operate as a waiver
of any rights of any holder of such Note. As used herein, the term “this Agreement” and references thereto shall mean
this Agreement as it may from time to time be amended or supplemented.

 

Section 17.4.          Notes
Held by Obligors, Etc. Solely for the purpose of determining whether the holders of the requisite percentage of the aggregate
principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent to be given under this Agreement
or the Notes, or have directed the taking of any action provided herein or in the Notes to be taken upon the direction of the holders
of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or indirectly owned by any
Obligor or any of its Affiliates shall be deemed not to be outstanding.

to the extent otherwise provided in Section 7.4, all notices and communications provided for hereunder shall be in writing and

to the Company in writing;

 

(iii)        if
to any other holder of any Note, to such holder at such address as such other holder shall have specified to the Company in writing;
or

 

(iv)        if
to the Company, to the Company at its address set forth at the beginning hereof to the attention of the Chief Financial Officer

Notices under this Section 18 will be deemed
given only when actually received.

document, instrument, financial statement, report, notice or other communication delivered in connection with this Agreement shall

(c)          This
Agreement and the Notes have been prepared and signed in English and the parties hereto agree that the English version hereof and
thereof (to the maximum extent permitted by applicable law) shall be the only version valid for the purpose of the interpretation
and construction hereof and thereof notwithstanding the preparation of any translation into another language hereof or thereof,
whether official or otherwise or whether prepared in relation to any proceedings which may be brought in Canada or any other jurisdiction
in respect hereof or thereof.

 

Section
19.         Reproduction of Documents.

 

This Agreement and
all documents relating thereto, including, without limitation, (a) consents, waivers and modifications that may hereafter be executed,
(b) documents received by any Purchaser at the Closing or by any Additional Purchaser (except the Notes themselves), and (c) financial
statements, certificates and other information previously or hereafter furnished to any Purchaser or any Additional Purchaser,
may be reproduced by such Purchaser or such Additional Purchaser by any photographic, photostatic, electronic, digital or other
similar process and such Purchaser or such Additional Purchaser may destroy any original document so reproduced. The Company agrees
and stipulates that, to the extent permitted by applicable law, any such reproduction shall be admissible in evidence as the original
itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction
was made by such Purchaser or such Additional Purchaser in the regular course of business) and any enlargement, facsimile or further
reproduction of such reproduction shall likewise be admissible in evidence. This Section 19 shall not prohibit the Company or any
other holder of Notes from contesting any such reproduction to the same extent that it could contest the original, or from introducing
evidence to demonstrate the inaccuracy of any such reproduction.

Section
20.         Confidential Information.

 

For the purposes of
this Section 20, “Confidential Information” means information delivered to any Purchaser or any Additional Purchaser
by or on behalf of any Obligor or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this
Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received
by such Purchaser or such Additional Purchaser as being confidential information of the Obligors or such Subsidiary, provided that
such term does not include information that (a) was publicly known or otherwise known to such Purchaser or such Additional
Purchaser prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by such
Purchaser or such Additional Purchaser or any person acting on such Purchaser’s or such Additional Purchaser’s behalf,
(c) otherwise becomes known to such Purchaser or such Additional Purchaser other than through disclosure by any Obligor or
any Subsidiary or (d) constitutes financial statements delivered to such Purchaser or such Additional Purchaser under Section 7.1
that are otherwise publicly available. Each Purchaser and each Additional Purchaser will maintain the confidentiality of such Confidential
Information in accordance with procedures adopted by such Purchaser or such Additional Purchaser in good faith to protect confidential
information of third parties delivered to such Purchaser or such Additional Purchaser, provided that such Purchaser or such Additional
Purchaser may deliver or disclose Confidential Information to (i) its directors, officers, employees, agents, attorneys, trustees
and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by its Notes),
(ii) its financial advisors and other professional advisors who agree to hold confidential the Confidential Information substantially
in accordance with the terms of this Section 20, (iii) any other holder of any Note, (iv) any Institutional Investor
to which it sells or offers to sell such Note or any part thereof or any participation therein (if such Person has agreed in writing
prior to its receipt of such Confidential Information to be bound by the provisions of this Section 20), (v) any Person
from which it offers to purchase any security of any Obligor (if such Person has agreed in writing prior to its receipt of such
Confidential Information to be bound by the provisions of this Section 20), (vi) any federal or state regulatory authority
having jurisdiction over such Purchaser or such Additional Purchaser, (vii) the NAIC or the SVO or, in each case, any similar
organization, or any nationally recognized rating agency that requires access to information about such Purchaser’s or such
Additional Purchaser’s investment portfolio, or (viii) any other Person to which such delivery or disclosure may be
necessary or appropriate (w) to effect compliance with any law, rule, regulation or order applicable to such Purchaser or
such Additional Purchaser, (x) in response to any subpoena or other legal process, (y) in connection with any litigation
to which such Purchaser or such Additional Purchaser is a party or (z) if an Event of Default has occurred and is continuing,
to the extent such Purchaser or such Additional Purchaser may reasonably determine such delivery and disclosure to be necessary
or appropriate in the enforcement or for the protection of the rights and remedies under such Purchaser’s or such Additional
Purchaser Notes and this Agreement. Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound
by and to be entitled to the benefits of this Section 20 as though it were a party to this Agreement. On reasonable request by
any Obligor in connection with the delivery to any holder of a Note of information required to be delivered to such holder under
this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder
will enter into an agreement with the Obligors embodying the provisions of this Section 20.

 

Section
21.         Substitution of Purchaser.

 

Each Purchaser and
each Additional Purchaser shall have the right to substitute any one of its Affiliates as the purchaser of the Notes that it has
agreed to purchase hereunder, by written notice to the Obligors, which notice shall be signed by both such Purchaser or such Additional
Purchaser and such Affiliate, shall contain such Affiliate’s agreement to be bound by this Agreement and shall contain a
confirmation by such Affiliate of the accuracy with respect to it of the representations set forth in Section 6. Upon receipt of
such notice, any reference to such Purchaser or such Additional Purchaser in this Agreement (other than in this Section 21),
shall be deemed to refer to such Affiliate in lieu of such original Purchaser or such original Additional Purchaser. In the event
that such Affiliate is so substituted as a Purchaser or an Additional Purchaser hereunder and such Affiliate thereafter transfers
to such original Purchaser or such original Additional Purchaser all of the Notes then held by such Affiliate, upon receipt by
any Obligor of notice of such transfer, any reference to such Affiliate as a “Purchaser” or an “Additional Purchaser”
in this Agreement (other than in this Section 21), shall no longer be deemed to refer to such Affiliate, but shall refer to
such original Purchaser or such original Additional Purchaser, and such original Purchaser or such original Additional Purchaser
shall again have all the rights of an original holder of the Notes under this Agreement.

Section
22.         Prepayment for Tax Reasons; Noteholder Sanctions Event.

 

Section 22.1.          Prepayment
for Tax Reasons. (a) If at any time as a result of a Change in Tax Law (as defined below) the Company is or becomes obligated
to make any Additional Payments (as defined below) in respect of any payment on account of any of the Notes, the Company may give
the holders of all affected Notes irrevocable written notice (each, a “Tax Prepayment Notice”) of the prepayment
of such affected Notes on a specified prepayment date (which shall be a Business Day not less than 30 days nor more than 60 days
after the date of such notice) and the circumstances giving rise to the obligation of the Company to make any Additional Payments
and the amount thereof and stating that all of the affected Notes shall be prepaid on the date of such prepayment at 100% of the
principal amount so prepaid together with interest accrued thereon to the date of such prepayment but without payment of any Make-Whole
Amount, except in the case of an affected Note if the holder of such Note shall, by written notice given to the Company no more
than 20 days after receipt of the Tax Prepayment Notice, reject such prepayment of such Note (each, a “Rejection Notice”).
The form of Rejection Notice shall also accompany the Tax Prepayment Notice and shall state with respect to each Note covered thereby
that execution and delivery thereof by the holder of such Note shall operate as a permanent waiver of such holder’s right
to receive the Additional Payments arising as a result of the circumstances described in the Tax Prepayment Notice in respect of
all future payments on such Note (but not of such holder’s right to receive any Additional Payments that arise out of circumstances
not described in the Tax Prepayment Notice or which exceed the amount of the Additional Payment described in the Tax Prepayment
Notice), which waiver shall be binding upon all subsequent transferees of such Note. The Tax Prepayment Notice having been given
as aforesaid to each holder of the affected Notes, the principal amount of such Notes together with interest accrued thereon to
the date of such prepayment shall become due and payable on such prepayment date, except in the case of Notes the holders of which
shall timely give a Rejection Notice as aforesaid.

 

(b)          No
prepayment of the Notes pursuant to this Section 22.1 shall affect the obligation of the Company to pay Additional Payments
in respect of any payment made on or prior to the date of such prepayment. For purposes of this Section 22.1, any holder of
more than one affected Note may act separately with respect to each affected Note so held (with the effect that a holder of more
than one affected Note may accept such offer with respect to one or more affected Notes so held and reject such offer with respect
to one or more other affected Notes so held).

 

(c)          The
Company may not offer to prepay or prepay Notes pursuant to this Section 22.1 (i) if a Default or Event of Default then exists,
(ii) until the Company shall have taken commercially reasonable steps to mitigate the requirement to make the related Additional
Payments or (iii) if the obligation to make such Additional Payments directly results or resulted from actions taken by the Company
or any Subsidiary (other than actions required to be taken under applicable law), and any Tax Prepayment Notice given pursuant
to this Section 22.1 shall certify to the foregoing and describe such mitigation steps, if any.

 

    		-54-	 

    	Waste Connections, Inc.	Note Purchase Agreement

    

 

(d)          For
purposes of this Section 22.1: “Additional Payments” means additional amounts (including any related indemnity)
required to be paid to a holder of any Note pursuant to Section 23 by reason of a Change in Tax Law; and a “Change
in Tax Law” means (individually or collectively with one or more prior changes) (i) an amendment to, or change in, any
law, treaty, protocol, rule or regulation of Canada or any other Taxing Jurisdiction after the date of the Assumption Agreement,
or an amendment to, or change in, an official interpretation or application of such law, treaty, protocol, rule or regulation after
the date of the Assumption Agreement which amendment or change is in force and continuing and meets the opinion and certification
requirements described below or (ii) in the case of any other jurisdiction that becomes a Taxing Jurisdiction after the date of
the Assumption Agreement an amendment to, or change in, any law, treaty, protocol, rule or regulation of such jurisdiction, or
an amendment to, or change in, an official interpretation or application of such law, treaty, protocol, rule or regulation, in
any case after such jurisdiction shall have become a Taxing Jurisdiction, which amendment or change is in force and continuing
and meets such opinion and certification requirements. No such amendment or change shall constitute a Change in Tax Law unless
the same would in the opinion of the Company (which shall be evidenced by an Officer’s Certificate of the Company, which
shall be delivered to all holders of the Notes prior to or concurrently with the Tax Prepayment Notice in respect of such Change
in Tax Law) affect the deduction or require the withholding of any Tax imposed by such Taxing Jurisdiction on any payment payable
on the Notes.

 

Section 22.2.          Prepayment
in Connection with a Noteholder Sanctions Event.

 

(a)          Upon
the Company’s receipt of notice from any Affected Noteholder that a Noteholder Sanctions Event has occurred (which notice
shall refer specifically to this Section 22.2(a) and describe in reasonable detail such Noteholder Sanctions Event), the Company
shall promptly, and in any event within 10 Business Days, make an offer (the “Sanctions Prepayment Offer”) to
prepay the entire unpaid principal amount of Notes held by such Affected Noteholder (the “Affected Notes”),
together with interest thereon to the prepayment date selected by the Company with respect to each Affected Note but without payment
of any Make-Whole Amount with respect thereto, which prepayment shall be on a Business Day not less than 30 days and not more than
60 days after the date of the Sanctions Prepayment Offer (the “Sanctions Prepayment Date”). Such Sanctions Prepayment
Offer shall provide that such Affected Noteholder notify the Company in writing by a stated date (the “Sanctions Prepayment
Response Date”), which date is not later than 10 Business Days prior to the stated Sanctions Prepayment Date, of its
acceptance or rejection of such prepayment offer. If such Affected Noteholder does not notify the Company as provided above, then
the holder shall be deemed to have accepted such offer.

 

(b)          Subject
to the provisions of subparagraphs (c) and (d) of this Section 8.4, the Company shall prepay on the Sanctions Prepayment Date
the entire unpaid principal amount of the Affected Notes held by such Affected Noteholder who has accepted (or has been deemed
to have accepted) such prepayment offer (in accordance with subparagraph (a)), together with interest thereon to the Sanctions
Prepayment Date with respect to each such Affected Note, but without payment of any Make-Whole Amount with respect thereto.

 

    		-55-	 

    	Waste Connections, Inc.	Note Purchase Agreement

    

 

(c)          If
a Noteholder Sanctions Event has occurred but the Company and/or its Controlled Entities have taken such action(s) in relation
to their activities so as to remedy such Noteholder Sanctions Event (with the effect that a Noteholder Sanctions Event no longer
exists, as reasonably determined by such Affected Noteholder) prior to the Sanctions Prepayment Date, then the Company shall no
longer be obliged or permitted to prepay such Affected Notes in relation to such Noteholder Sanctions Event. If the Company and/or
its Controlled Entities shall undertake any actions to remedy any such Noteholder Sanctions Event, the Company shall keep the holders
reasonably and timely informed of such actions and the results thereof.

 

(d)          If
any Affected Noteholder that has given written notice to the Company of its acceptance of (or has been deemed to have accepted)
the Company’s prepayment offer in accordance with subparagraph (a) also gives notice to the Company prior to the relevant
Sanctions Prepayment Date that it has determined (in its sole discretion) that it requires clearance from any Governmental Authority
in order to receive a prepayment pursuant to this Section 8.4, the principal amount of each Note held by such Affected Noteholder,
together with interest accrued thereon to the date of prepayment, shall become due and payable on the later to occur of (but in
no event later than the Maturity Date of the relevant Note) (i) such Sanctions Prepayment Date and (ii) the date that is 10 Business
Days after such Affected Noteholder gives notice to the Company that it is entitled to receive a prepayment pursuant to this Section 8.4
(which may include payment to an escrow account designated by such Affected Noteholder to be held in escrow for the benefit of
such Affected Noteholder until such Affected Noteholder obtains such clearance from such Governmental Authority), and in any event,
any such delay in accordance with the foregoing clause (ii) shall not be deemed to give rise to any Default or Event of Default.

 

(e)          Promptly,
and in any event within 5 Business Days, after the Company’s receipt of notice from any Affected Noteholder that a Noteholder
Sanctions Event shall have occurred with respect to such Affected Noteholder, the Company shall forward a copy of such notice to
each other holder of Notes.

 

(f)          The
Company shall promptly, and in any event within 10 Business Days, give written notice to the holders after the Company or any Controlled
Entity having been notified that (i) its name appears or may in the future appear on a State Sanctions List or (ii) it is in violation
of, or is subject to the imposition of sanctions under, any U.S. Economic Sanctions Laws, in each case which notice shall describe
the facts and circumstances thereof and set forth the action, if any, that the Company or a Controlled Entity proposes to take
with respect thereto.

 

(g)          The
foregoing provisions of this Section 22.2 shall be in addition to any rights or remedies available to any holder of Notes
that may arise under this Agreement as a result of the occurrence of a Noteholder Sanctions Event; provided, that, if the
Notes shall have been declared due and payable pursuant to Section 12.1 as a result of the events, conditions or actions of
the Company or its Controlled Entities that gave rise to a Noteholder Sanctions Event, the remedies set forth in Section 12 shall
control.

Section
23.         Tax Indemnification; FATCA Information.

 

(a)          All
payments whatsoever under this Agreement and the Notes will be made by the Company in lawful currency of the United States of America
free and clear of, and without liability for withholding or deduction for or on account of, any present or future Taxes of whatever
nature imposed or levied by or on behalf of any jurisdiction (other than the United States or any political subdivision thereof)
in which (i) the Company is then incorporated or resident for tax purposes or any jurisdiction from or (ii) through which
payment is made by or on behalf of the Company (or, in the case of clauses (i) and (ii), any political subdivision or taxing authority
of or in such jurisdiction) (hereinafter a “Taxing Jurisdiction”), unless the withholding or deduction of such
Tax is compelled by law.

 

(b)          If
any deduction or withholding for any Tax of a Taxing Jurisdiction shall at any time be required in respect of any amounts to be
paid by the Company under this Agreement or the Notes, the Company will pay to the relevant Taxing Jurisdiction the full amount
required to be withheld, deducted or otherwise paid before penalties attach thereto or interest accrues thereon and pay to each
holder of a Note such additional amounts, as additional interest on the Notes as may be necessary in order that the net amounts
paid to such holder pursuant to the terms of this Agreement or the Notes after such deduction, withholding or payment (including
any required deduction or withholding of Tax of a Taxing Jurisdiction on or with respect to such additional amount), shall be not
less than the amounts then due and payable to such holder under the terms of this Agreement or the Notes before the assessment
of such Tax, provided that no payment of any additional amounts shall be required to be made for or on account of:

 

(i)          any
Tax that would not have been imposed but for the existence of any present or former connection between such holder or beneficial
owner (or a fiduciary, settlor, beneficiary, member of, shareholder of, or possessor of a power over, such holder or beneficial
owner, if such holder or beneficial owner is an estate, trust, partnership or corporation or any Person other than the holder or
beneficial owner to whom the Notes or any amount payable thereon is attributable for the purposes of such Tax) and the Taxing Jurisdiction,
other than the mere holding of the relevant Note or the receipt of payments thereunder or in respect thereof or the exercise of
remedies in respect thereof, including such holder or beneficial owner (or such other Person described in the above parenthetical)
being or having been a citizen or resident or national thereof, having been organized under the laws thereof, or being or having
been present or engaged in trade or business therein or having or having had an establishment, office, fixed base or branch therein;

 

(ii)         any
Tax that would not have been imposed but for the delay or failure by such holder or beneficial owner (following a written request
by, or by an agent of, the Company) in the accurate filing with the Company or the relevant Taxing Jurisdiction of Forms (as defined
below) that are required to be filed by such holder or beneficial owner to avoid or reduce such Taxes (including for such purpose
any refilings or renewals of filings that may from time to time be required by the relevant Taxing Jurisdiction), provided
that the filing of such Forms would not (in such holder’s reasonable judgment) result in any confidential or proprietary
income tax return information being revealed, either directly or indirectly, to any Person and such delay or failure could have
been lawfully avoided by such holder, and provided further that such holder shall be deemed to have satisfied the requirements
of this clause (b)(ii) upon the good faith completion and submission of such Forms (including refilings or renewals of filings)
as may be specified in a written request of, or an agent of, the Company no later than 30 days after receipt by such holder of

(iii)        any
Tax imposed under FATCA;

 

(iv)        any
Tax which is payable otherwise than by deduction or withholding from payments made under or with respect to the Notes;

 

(v)         any
Taxes that are imposed or withheld as a result of the presentation of the Notes for payment more than 30 days after the relevant
payment is first made available for payment to the holder or beneficial owners (except to the extent the holder would have been
entitled to additional amounts had the note been presented on the last day of such 30 day period);

 

(vi)        any
Tax that would not have been imposed if the holder dealt, at the applicable time, at “arm’s length” with the
Company, and is not a “specified shareholder” of the Company or a person who does not deal at arm's length, with such
a specified shareholder, all within the meaning of the ITA; or

 

(vii)       any
combination of clauses (i) and (vi) above;

 

provided further that in no event
shall the Company be obligated to pay such additional amounts to any holder (i) not resident in the United States of America in
excess of the amounts that the Company would be obligated to pay if such holder had been a resident of the United States of America
for purposes of, and eligible for the benefits of, any double taxation treaty from time to time in effect between Canada and the
United States of America or (ii) registered in the name of a nominee if under the law of the relevant Taxing Jurisdiction (or the
current regulatory interpretation of such law) securities held in the name of a nominee do not qualify for an exemption from the
relevant Tax and the Company shall have given timely notice of such law or interpretation to such holder.

 

(c)          By
acceptance of any Note, the holder of such Note agrees, subject to the limitations of clause (b)(ii) above, that it will from time
to time with reasonable promptness (x) duly and accurately complete and deliver to or as reasonably directed by, or by an
agent of, the Company all such forms, certificates, documents and returns provided to such holder by the Company (collectively,
together with instructions for completing the same, “Forms”) required to be filed by or on behalf of such holder
in order to avoid or reduce any such Tax pursuant to the provisions of an applicable statute, regulation or administrative practice
of the relevant Taxing Jurisdiction or of a tax treaty between the jurisdiction of the holder and such Taxing Jurisdiction and
(y) provide the Company and, if applicable, its agent with such information with respect to such holder as the Company may
reasonably request in order to complete any such Forms or comply with any backup withholding and information withholding requirements,
provided that nothing in this Section 23 shall require any holder to provide information with respect to any such Form
or otherwise if in the opinion of such holder such Form or disclosure of information would involve the disclosure of tax return
or other information that is confidential or proprietary to such holder, and provided further that each such holder shall
be deemed to have complied with its obligation under this paragraph with respect to any Form if such Form shall have been duly
completed and delivered by such holder to the Company and, if applicable, its agent or mailed to the appropriate taxing authority,
whichever is applicable, within 60 days following a written request of the Company (which request shall be accompanied by copies
of such Form and English translations of any such Form not in the English language) and, in the case of a transfer of any Note,
at least 90 days prior to the relevant interest payment date.

(d)          On
or before the date of the Assumption Agreement, the Company will furnish each Purchaser with copies of the appropriate Form (and
English translation if required as aforesaid) currently required to be filed in Canada pursuant to Section 23(b)(ii), if any,
and in connection with the transfer of any Note the Company will furnish the transferee of such Note with copies of any Form and
English translation then required.

 

(e)          If
any payment is made by the Company to or for the account of the holder of any Note after deduction for or on account of any Taxes,
and increased payments are made by the Company pursuant to this Section 23, then, if such holder at its sole discretion determines
that it has received or been granted a refund, relief, remission or repayment of such Taxes, such holder shall, without unreasonable
delay, reimburse to the Company such amount as such holder shall, in its sole discretion, determine to be attributable to the relevant
Taxes or deduction or withholding. Nothing herein contained shall interfere with the right of the holder of any Note to arrange
its tax affairs in whatever manner it thinks fit and, in particular, no holder of any Note shall be under any obligation to claim
relief from its corporate profits or similar tax liability in respect of such Tax in priority to any other claims, reliefs, credits
or deductions available to it or (other than as set forth in Section 23(b)(ii)) oblige any holder of any Note to disclose any information
relating to its tax affairs or any computations in respect thereof.

 

(f)          The
Company will furnish the holders of Notes, promptly and in any event within 60 days after the date of any payment by the Company
of any Tax in respect of any amounts paid under this Agreement or the Notes, the original tax receipt issued by the relevant taxation
or other authorities involved for all amounts paid as aforesaid (or if such original tax receipt is not available or must legally
be kept in the possession of the Company, a duly certified copy of the original tax receipt or any other reasonably satisfactory
evidence of payment), together with such other documentary evidence with respect to such payments as may be reasonably requested
from time to time by any holder of a Note.

 

(g)          If
the Company is required by any applicable law, as modified by the practice of the taxation or other authority of any relevant Taxing
Jurisdiction, to make any deduction or withholding of any Tax in respect of which the Company would be required to pay any additional
amount under this Section 23, but for any reason does not make such deduction or withholding with the result that a liability
in respect of such Tax is assessed directly against the holder of any Note, and such holder pays such liability, then the Company
will promptly reimburse such holder for such payment (including any related interest or penalties to the extent such interest or
penalties arise by virtue of a default or delay by the Company) upon demand by such holder accompanied by an official receipt (or
a duly certified copy thereof) issued by the taxation or other authority of the relevant Taxing Jurisdiction.

(h)          If
the Company makes payment to or for the account of any holder of a Note, including for the avoidance of doubt, pursuant to Section
23(g) and such holder is entitled to a refund of the Tax to which such payment is attributable upon the making of a filing (other
than a Form described above), then such holder shall, as soon as practicable after receiving written request from the Company (which
shall specify in reasonable detail and supply the refund forms to be filed) use reasonable efforts to complete and deliver such
refund forms to or as directed by the Company, subject, however, to the same limitations with respect to Forms as are set forth
above.

 

(i)          The
obligations of the Company under this Section 23 shall survive the payment or transfer of any Note and the provisions of this Section
23 shall also apply to successive transferees of the Notes.

 

(j)          (i)
Each holder that is not a United States person as defined in Section 7701(a)(30) of the Code hereby agrees to deliver to the Company,
on or before the later of the date of the Assumption Agreement and the date it becomes a holder under this Agreement and thereafter
upon reasonable request of the Company, either a completed and signed IRS Form W-8BEN, W-8BEN-E or W-8ECI (or other applicable
IRS Form W-8 or other successor form, together with applicable attachments), as may be applicable to it, as required in order to
claim the applicable U.S. withholding exemption.

 

(ii)         Each
holder that is a United States person as defined in Section 7701(a)(30) of the Code, agrees to deliver to the Company, on or before
the later of the date of the Assumption Agreement and the date it becomes a holder under this Agreement and thereafter upon reasonable
request of the Company, a completed and signed IRS Form W-9 (or other successor form) certifying that such holder is completely
exempt from U.S. federal backup withholding tax.

 

(iii)        Each
holder agrees to deliver, on or before the later of the date of the Assumption Agreement and the date it becomes a holder under
this Agreement and thereafter upon reasonable request of the Company, the applicable tax form or documentation as required in order
to claim an exemption from any taxes imposed under FATCA (including, solely for this purpose, any amendments after the date hereof).

 

(iv)        If
the holder is not the beneficial owner of the Notes, the representations in Section 23(k) and the covenants set forth in clauses
(i) through (iii) above shall apply with respect to the beneficial owners. The holders shall collect the tax documentation described
above in clauses (i) through (iii) from the beneficial owners and, if the holder is not a United States person as defined in Section
7701(a)(30), forward the beneficial owner tax documentation to the Company along with a completed and signed IRS Form W-8IMY (or
other successor form) and, if the holder is a United States person as defined in Section 7701(a)(30), submit a completed and signed
IRS Form W-9 for such holder.

(v)         Notwithstanding
anything to the contrary, (i) neither the Company nor any Subsidiary shall be required to pay any additional amounts or any
indemnity or other payment under this Section 23 or otherwise to or for the account of any holders or beneficial owners for any
Taxes resulting from a holder’s or beneficial owner’s breach of Section 23(k) or this Section 23(j), (ii) holders
and beneficial owners hereby severally agree to indemnify the Company (to the extent permitted by applicable law) for any such
Taxes imposed on or collected from the Company or any of its Subsidiaries (including any such Taxes imposed or collected with respect
to any intercompany loan or other financing with or among Subsidiaries of the Company) resulting from such breach, and (iii) the
Company shall be entitled to treat the Notes as issued directly by a Subsidiary that is a United States person for U.S. federal
income tax purposes and make any deduction or withholding of U.S. federal income tax accordingly and on the basis of the information
and documentation to be delivered pursuant to this Section 23(j).

 

(vi)        For
the avoidance of doubt, (i) the references to “Purchaser” in Section 23(k) and references to “holder” in
this Section 23(j) shall be read interchangeably and (ii) the terms “holder” and “beneficial owner” in
Section 23(k) or this Section 23(j) shall be in reference to both the holders (including, for the avoidance of doubt, any nominees)
and beneficial owners of the Notes as of the date of the Assumption Agreement and any subsequent holders and beneficial owners,
respectively.

 

(k)          (i)
Each Purchaser and each holder that is not a United States person as defined in Section 7701(a)(30) of the Code hereby represents
that, as of the date of the Assumption Agreement or, if later, the date such holder becomes a holder of a Note, (x) it qualifies
for a complete exemption from U.S. federal withholding tax with respect to payments of interest pursuant to an applicable income
tax treaty to which the United States is a party; (y) it could claim the portfolio interest exemption (with respect to payments
of interest on the Notes if the Notes were treated as issued by a Subsidiary that is a United States person) and is not a “bank”
within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Company within the meaning
of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the
Code; or (z) such Purchaser's interest from the Notes will be effectively connected with a trade or business in the United States,
and, in each case, such Purchaser thereby qualifies for a complete exemption from any U.S. withholding taxes (other than taxes
imposed under FATCA, which shall be addressed under Section 23(k)(ii) below).

 

(ii) Each Purchaser and each holder
represents that, as of the date of the Assumption Agreement or, if later, the date such holder becomes a holder of a Note, in regard
to payments of interest and principal on the Notes (if the Notes were treated as if they were issued by a Subsidiary that is a
United States person), it (and any intermediary through which it will hold its Notes) qualifies for a complete exemption from any
taxes imposed under FATCA.

24.         Miscellaneous.

in any Supplement) by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and
permitted assigns (including, without limitation, any subsequent holder of a Note) whether so expressed or not. Nothing in this

Section 24.2.          Payments
Due on Non-Business Days. Anything in this Agreement or the Notes to the contrary notwithstanding (but without limiting the
requirement in Section 8.2 that notice of any optional prepayment specify a Business Day as the date fixed for such prepayment),
any payment of principal of or Make-Whole Amount or interest on any Note that is due on a date other than a Business Day shall
be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable
on such next succeeding Business Day; provided that if the maturity date of any Note is a date other than a Business Day,
the payment otherwise due on such maturity date shall be made on the next succeeding Business Day and shall include the additional
days elapsed in the computation of interest payable on such next succeeding Business Day.

 

Section 24.3.          Accounting
Terms. (a) Generally. All accounting terms used herein which are not expressly defined in this Agreement have the meanings
respectively given to them in accordance with GAAP. Except as otherwise specifically provided herein, (i) all computations made
pursuant to this Agreement shall be made in accordance with GAAP, and (ii) all financial statements shall be prepared in accordance
with GAAP. For purposes of determining compliance with this Agreement (including, without limitation, Section 9, Section 10
and the definition of “Indebtedness”), any election by the Company to measure any financial liability using
fair value (as permitted by Financial Accounting Standards Board Accounting Standards Codification Topic No. 825-10-25 – Fair
Value Option, International Accounting Standard 39 – Financial Instruments: Recognition and Measurement
or any similar accounting standard) shall be disregarded and such determination shall be made as if such election had not been
made.

 

(b)          Changes
in GAAP. If at any time any change in GAAP would affect the computation of any financial ratio or requirement set forth in
this Agreement, and either the Company or the Required Holders shall so request, the holders and the Company shall negotiate in
good faith to amend such ratio or requirement to preserve the original intent thereof in light of such change in GAAP (subject
to the approval of the Required Holders); provided, that until so amended, (i) such ratio or requirement shall continue
to be computed in accordance with GAAP prior to such change therein and (ii) the Company shall provide to the holders financial
statements and other documents required under this Agreement or as reasonably requested hereunder setting forth a reconciliation
between calculations of such ratio or requirement made before and after giving effect to such change in GAAP. Without limiting
the foregoing, leases shall continue to be classified and accounted for on a basis consistent with that reflected in the Audited
Financial Statements for all purposes of this Agreement, notwithstanding any change in GAAP relating thereto, unless the parties
hereto shall enter into a mutually acceptable amendment addressing such changes, as provided for above.

provision in any other jurisdiction.

 

Section 24.5.          Construction,
Etc. Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each
other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision)
be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person,
or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly

Section 24.7.          Governing
Law. This Agreement shall be construed and enforced in accordance with, and the rights of the parties shall be governed by,

Section 24.8.          Jurisdiction
and Process; Waiver of Jury Trial. (a) The Company irrevocably submits to the non-exclusive jurisdiction of any New York State
or federal court sitting in the Borough of Manhattan, The City of New York, over any suit, action or proceeding arising out of
or relating to this Agreement or the Notes. To the fullest extent permitted by applicable law, the Company irrevocably waives and
agrees not to assert, by way of motion, as a defense or otherwise, any claim that it is not subject to the jurisdiction of any
such court, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought
in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient
forum.

 

(b)          The
Company agrees, to the fullest extent permitted by applicable law, that a final judgment in any suit, action or proceeding of the
nature referred to in Section 24.8(a) brought in any such court shall be conclusive and binding upon it subject to rights
of appeal, as the case may be, and may be enforced in the courts of the United States of America or the State of New York (or any
other courts to the jurisdiction of which it or any of its assets is or may be subject) by a suit upon such judgment.

 

(c)          The
Company consents to process being served by or on behalf of any holder of Notes in any suit, action or proceeding of the nature
referred to in Section 24.8(a) by mailing a copy thereof by registered or certified mail, return receipt requested (or any
substantially similar form of mail) postage prepaid, return receipt or delivery confirmation requested, or delivering a copy thereof
in the manner for delivery of notices specified in Section 18, to Waste Connections US, Inc., a Delaware corporation, as its agent
for the purpose of accepting service of any process in the United States. The Company agrees that such service upon receipt (i) shall
be deemed in every respect effective service of process upon it in any such suit, action or proceeding and (ii) shall, to
the fullest extent permitted by applicable law, be taken and held to be valid personal service upon and personal delivery to it.
Notices hereunder shall be conclusively presumed received as evidenced by a delivery receipt furnished by the United States Postal
Service or any reputable commercial delivery service.

 

(d)          Nothing
in this Section 24.8 shall affect the right of any holder of a Note to serve process in any manner permitted by law, or limit any
right that the holders of any of the Notes may have to bring proceedings against the Company in the courts of any appropriate jurisdiction
or to enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction.

Section 24.9.          Obligation
to Make Payment in Dollars. Any payment on account of an amount that is payable hereunder or under the Notes in Dollars which
is made to or for the account of any holder in any other currency, whether as a result of any judgment or order or the enforcement
thereof or the realization of any security or the liquidation of the Company, shall constitute a discharge of the obligation of
the Company under this Agreement or the Notes only to the extent of the amount of Dollars which such holder could purchase in the
foreign exchange markets in London, England, with the amount of such other currency in accordance with normal banking procedures
at the rate of exchange prevailing on the London Banking Day following receipt of the payment first referred to above. If the amount
of Dollars that could be so purchased is less than the amount of Dollars originally due to such holder, the Company agrees to the
fullest extent permitted by law, to indemnify and save harmless such holder from and against all loss or damage arising out of
or as a result of such deficiency. This indemnity shall, to the fullest extent permitted by law, constitute an obligation separate
and independent from the other obligations contained in this Agreement and the Notes, shall give rise to a separate and independent
cause of action, shall apply irrespective of any indulgence granted by such holder from time to time and shall continue in full
force and effect notwithstanding any judgment or order for a liquidated sum in respect of an amount due hereunder or under the
Notes or under any judgment or order. As used herein the term “London Banking Day” shall mean any day other
than Saturday or Sunday or a day on which commercial banks are required or authorized by law to be closed in London, England.

 

Section 24.10.         Interest
Act (Canada). (a) To the extent permitted under applicable law, any provision of the Interest Act (Canada) or the Judgment
Interest Act (Alberta) which restricts any rate of interest set forth herein shall be inapplicable to this Agreement and is
hereby waived by the Company.

 

(b)          The
theory of deemed reinvestment shall not apply to the calculation of interest or payment of fees or other amounts hereunder, notwithstanding
anything contained in this Agreement, acceptance or other evidence of indebtedness or in any other agreement relating to the Notes
now or hereafter taken by any holder for the obligations of the Company under this Agreement, or any other instrument referred
to herein, and all interest and fees payable by the Company to the holders, shall accrue from day to day, computed as described
herein or in the Notes in accordance with the “nominal rate” method of interest calculation.

 

(c)          Where,
in this Agreement or in the Notes, any rate of interest, fees or discount is to be calculated on the basis of a 365/366-day year,
such rate is, for the purpose of the Interest Act (Canada), equivalent to the said rate (i) multiplied by the actual
number of days in the one year period beginning on the first day of the period of calculation and (ii) divided by 365 or 366,
as applicable. Where, in this Agreement, any rate of interest, fees or discount is to be calculated on the basis of a 360-day year,
such rate is, for the purpose of the Interest Act (Canada), equivalent to the said rate (i) multiplied by the actual
number of days in the one year period beginning on the first day of the period of calculation and (ii) divided by 360.

interest which accrues after the commencement of any case or proceeding in bankruptcy or for the reorganization of any company),
fees, charges, expenses, attorneys’ fees and any other sum chargeable to any Subordinating Note Party or due in respect of
the aggregate unpaid amount of all advances, indebtedness, loans, payables and other extensions of credit and obligations made
by a Subordinating Note Party to another Subordinating Note Party as holder (the “Intercompany Indebtedness”),
that the payment of any Intercompany Indebtedness is subordinated in right of payment, to the extent and in the manner provided
in this Section 24.11, to the payment in full of all obligations under this Agreement, any Subsidiary Guaranty and the Notes
(collectively, the “Obligations”), and that the subordination is for the benefit of the holders of the Notes.
Without limitation of the foregoing, so long as no Event of Default has occurred and is continuing, (1) as to any Permitted Intercompany
Financings, any Subordinating Note Party may make and receive any (x) payments of principal and interest, including, without limitation,
prepayments of principal, (y) applicable expense or indemnity payments payable in accordance with the terms thereof and (z) refinancings,
replacements, renewals or extensions of such Permitted Intercompany Financings to the extent permitted by this Agreement and subordinate
to the Obligations in accordance with this Section 24.11 and (2) as to Intercompany Indebtedness other than Permitted Intercompany
Financings, any Subordinating Note Party may make and receive any (x) regularly scheduled payments of principal and interest as
and when due, (y) applicable expense or indemnity payments payable in accordance with the terms thereof and (z) refinancings, replacements,
renewals or extensions of such Intercompany Indebtedness to the extent permitted by this Agreement and subordinate to the Obligations
in accordance with this Section 24.11; provided, that in the event that any Subordinating Note Party receives
any payment of any such Intercompany Indebtedness at a time when such payment is prohibited by this Section, such payment shall
be held by such Subordinating Note Party, in trust for the benefit of, and shall be paid forthwith over and delivered, upon written
request, to the holders of Notes (provided that, in the event that any other holder of senior Indebtedness permitted under
this Agreement has the same right to receive such payments, the Company shall be permitted to pay such payment or distribution
to the applicable agent and to the holders of such other senior Indebtedness on a pari passu basis, pro rata, based on outstanding
principal amount (so long as such other senior Indebtedness contains a similar pari passu provision)).

 

(b)          Each
of the Subordinating Note Parties, for itself and on behalf of its Subsidiaries, by its acceptance of any Intercompany Indebtedness,
(i) authorizes the Required Holders to demand specific performance of the terms of this Section 24.11 at any time when
any holder of Intercompany Indebtedness shall have failed to comply with any provisions of this Section 24.11 which are applicable
to it and (ii) irrevocably waives to the extent permitted under applicable law any defense based on the adequacy of a remedy
at law, which might be asserted as a bar to such remedy of specific performance.

(c)          Upon
any distribution of assets of any Subordinating Note Party in any dissolution, winding up, liquidation or reorganization (whether
in bankruptcy, insolvency or receivership proceedings or upon an assignment for the benefit of creditors or otherwise): (i) the
holders of the Notes shall first be entitled to receive payment in full in cash of the Obligations before any holder of Intercompany
Indebtedness is entitled to receive any payment on account of such Intercompany Indebtedness; (ii) any payment or distribution
of assets of any Subordinating Note Party of any kind or character, whether in cash, property or securities, to which any such
holder of Intercompany Indebtedness would be entitled except for the provisions of this Section 24.11(c), shall be paid by
the liquidating trustee or agent or other Person making such payment or distribution directly to the holders of the Notes, to the
extent necessary to make payment in full of all Obligations remaining unpaid after giving effect to any concurrent payment or distribution
or provisions therefor to the holders of the Notes; (iii) in the event that, notwithstanding the foregoing provisions of this Section 24.11(c),
any payment or distribution of assets of any Subordinating Note Party of any kind or character, whether in cash, property or securities,
shall be received by any such holder of Intercompany Indebtedness on account of Intercompany Indebtedness before the discharge
of the Obligations, such payment or distribution shall be received and held in trust for and shall be paid over to the holders

there has been no change in the financial condition, operations, business, properties or prospects of the Company or any of its
Subsidiaries except changes that individually or in the aggregate would not reasonably be expected to have a Material Adverse
Effect. There is no fact known to the Obligors that would reasonably be expected to have a Material Adverse Effect that has not

Section 5.5.          Financial

and its Subsidiaries listed on Schedule 5.5 to the [Number] Supplement. All of said financial statements (including in each

statements or otherwise disclosed in the Disclosure Documents.

 

Section 5.13.         Private
Offering by the Obligors. None of the Obligors nor anyone acting on its behalf has offered the Series 2008A Notes, or
any securities required to be integrated under any federal or state securities laws, for sale to, or solicited any offer to buy

more than [______] other Institutional Investors, each of which has been offered the Series 2008A Notes at a private sale for investment.
None of the Obligors nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale
of the Series 2008A Notes to the registration requirements of Section 5 of the Securities Act or to the registration
requirements of any securities or blue sky laws of any applicable jurisdiction.

 

Section 5.14.         Use
of Proceeds; Margin Regulations. The Obligors will apply the proceeds of the sale of the Series ______ Notes to ______________________________
and for general corporate purposes of the Obligors. No part of the proceeds from the sale of the Series ______ Notes pursuant
to the [Number] Supplement will be used, directly or indirectly, for the purpose of buying or carrying any margin stock within
the meaning of Regulation U of the Board of Governors of the Federal Reserve System (12 CFR 221), or for the purpose of buying
or carrying or trading in any securities under such circumstances as to involve the Obligors in a violation of Regulation X
of said Board (12 CFR 224) or to involve any broker or dealer in a violation of Regulation T of said Board (12 CFR 220). Margin
stock does not constitute more than [___%] of the value of the consolidated assets of the Company and its Subsidiaries and the
Company does not have any present intention that margin stock will constitute more than [___%] of the value of such assets. As
used in this Section, the terms “margin stock” and “purpose of buying or carrying” shall
have the meanings assigned to them in said Regulation U.

of all outstanding Indebtedness of the Company and its Subsidiaries as of [__________] (including a description of the obligors
and obligees, principal amount outstanding and collateral therefor, if any, and Guaranty thereof, if any), since which date there
has been no Material change in the amounts, interest rates, sinking funds, installment payments or maturities of the Indebtedness
of the Obligors. None of the Obligors is in default, and no waiver of default is currently in effect, in the payment of any principal
or interest on any Indebtedness of any Obligor, and no event or condition exists with respect to any Indebtedness of any Obligor
that, in each case, (i) has existed for such period of time as would permit (after the giving of appropriate notice, if required)
one or more Persons to cause such Indebtedness to become due and payable before its stated maturity or before its regularly scheduled
dates of payment and (ii) would reasonably be expected to have a Material Adverse Effect.

 

(b)          Except
as disclosed in Schedule 5.15 to the [Number] Supplement, none of the Obligors has agreed or consented to cause or permit
in the future (upon the happening of a contingency or otherwise) any of its property, whether now owned or hereafter acquired,
to be subject to a Lien [not permitted by Section 10.2].

 

(c)          None
of the Obligors are a party to, or otherwise subject to any provision contained in, any instrument evidencing Indebtedness of any
Obligor, any agreement relating thereto or any other agreement (including, but not limited to, its charter or other organizational
document) which limits the amount of, or otherwise imposes restrictions on the incurring of, Indebtedness of the Company, except

conducted and as presently contemplated, and (iii) is in good standing as a foreign corporation, partnership, limited liability
company or similar business entity and is duly authorized to do business in each jurisdiction in which its property or business
as presently conducted or contemplated makes such qualification necessary, except where a failure to be in good standing or so
qualified would not have a Material Adverse Effect

 

(c)No Subsidiary is a party to,
or otherwise subject to any legal, regulatory, contractual or other restriction (other than this Agreement, the 2016 NPA, the Bank
Credit Agreement and customary limitations imposed by corporate law or similar statutes) restricting the ability of such Subsidiary
to pay dividends out of profits or make any other similar distributions of profits to the Parent or any of its Subsidiaries that

Section 5.6.Compliance
with Laws, Other Instruments, Etc. The execution, delivery and performance by the Parent of the Assumption and Exchange Agreement

association, regulations or by-laws or shareholders agreement, (ii) conflict with or result in a breach of any of the terms,
conditions or provisions of any order, judgment, decree or ruling of any court, arbitrator or Governmental Authority applicable

or its Subsidiaries, and no event or condition exists with respect to any Indebtedness of the Parent or any Subsidiary, that, in

or more Persons to cause such Indebtedness to become due and payable before its stated maturity or before its regularly scheduled
dates of payment and (ii) would reasonably be expected to have a Material Adverse Effect.

 

     

     

    

 

(b)Except as disclosed in Schedule

is a party to, or otherwise subject to any provision contained in, any instrument evidencing Indebtedness of the Parent or such
Subsidiary, any agreement relating thereto or any other agreement (including, but not limited to, its charter or any other organizational
document) which limits the amount of, or otherwise imposes restrictions on the incurring of, Indebtedness of the Company, except

AMENDMENT TO 

SEPARATION BENEFITS PLAN AND EMPLOYMENT
AGREEMENT

 

This Amendment to Separation
Benefits Plan and Employment Agreement (this “Amendment”) is dated December 17, 2015 (the “Execution
Date”), and is by and between Waste Connections, Inc., a Delaware corporation (the “Company”), and
Ronald J. Mittelstaedt (“Executive”). The Company and Executive are referred to together herein as the “Parties.”
All capitalized terms not otherwise defined in this Amendment shall have the meaning set forth in the Employment Agreement (as
hereinafter defined).

 

RECITALS

 

WHEREAS, the Parties
entered into that certain Separation Benefits Plan and Employment Agreement, effective as of February 13, 2012 (the “Employment
Agreement”); and

 

WHEREAS, the Parties
desire to amend the Employment Agreement by this Amendment.

 

NOW, THEREFORE,
for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties hereby agree as follows:

 

 

1.Payments on
Change in Control. Section 10(a) of the Employment Agreement is hereby deleted and replaced in its entirety with the following:

 

“(a) Payments
on Change in Control. Notwithstanding any agreement evidencing an equity award held by Executive entered into prior to, on
or after the Effective Date to the contrary, no equity award held by Executive shall be subject to accelerated vesting based solely
upon the occurrence of a Change in Control (as defined below) unless the Compensation Committee of the Company, prior to the Change
in Control, reasonably determines in good faith that Executive’s equity awards will not be honored or assumed, or new rights
that substantially preserve the terms of Executive’s equity awards will not be substituted therefor, by Executive’s
employer (or the parent of such employer) immediately following the Change in Control (a “Change in Control Cancellation”).
For the avoidance of doubt, in the event of a Change in Control Cancellation, (1) the vesting and, if applicable, exercisability
of each of Executive’s equity awards subject to time-based vesting shall fully accelerate as of immediately prior to the
Change in Control and (2) the vesting and, if applicable, exercisability of each of Executive’s equity awards subject to
performance-based vesting (“Performance Awards”) shall be determined in accordance with the agreement evidencing
such Performance Award or, in the absence of any provision in the agreement evidencing such Performance Award pertaining to the
Change in Control, shall be accelerated in respect to one hundred percent (100%) of the shares subject thereto with any performance
goal(s) being deemed to have been achieved at one hundred percent (100%) of target. For further avoidance of doubt, in the absence
of a Change in Control Cancellation, if the terms of a Performance Award provide for accelerated vesting upon a termination of
employment following a Change in Control, such terms shall continue to control and, in the absence of any such terms, such Performance
Award shall be subject to accelerated vesting as provided in Sections 7 and 8 hereof. Furthermore, in the absence of a Change in
Control Cancellation, if any equity award held by Executive as of immediately prior to a Change in Control is a Performance Award
and the agreement evidencing such Performance Award does not provide for the determination of performance in connection with the
Change in Control (or provides for accelerated vesting based solely upon the occurrence of a Change in Control), then the applicable
performance goals in respect of such equity award shall be deemed to have been achieved at one hundred percent (100%) of target
and any such equity award shall vest and, if applicable, become exercisable on such date(s) the equity award would have vested
if the performance goal were achieved absent the Change in Control. Any Performance Award for which the performance goal is achieved
or deemed achieved in connection with a Change in Control shall constitute a ‘time-based equity award’ under Sections
7 and 8 hereof. For the avoidance of doubt and without limiting the preceding sentence, Executive shall be eligible for such payments
and benefits as provided under, and in accordance with the terms and conditions of, Sections 7 and 8 hereof in the event Executive’s
employment terminates in connection with or following a Change in Control.”

 

     

     

    

 

2. No Other Changes.
Except as provided in this Amendment, the Employment Agreement shall remain in full force and effect and remain unchanged.

 

3.Counterparts.
This Amendment may be executed in any number of counterparts, each of which shall be enforceable against the parties actually executing
such counterparts, and all of which together shall constitute one instrument. A facsimile, telecopy or other reproduction of this
Amendment may be executed by one or more parties and delivered by such party by facsimile or any similar electronic transmission
device pursuant to which the signature of or on behalf of each such party can be seen. Such execution and delivery shall be considered
valid, binding and effective for all purposes.

 

4.Governing Law.
The Agreement and this Amendment are together intended to be a Top Hat Plan and shall be interpreted, administered and enforced
in accordance with ERISA. It is expressly intended that ERISA preempt the application of state laws to the Agreement and this Amendment
to the maximum extent permitted by Section 514 of ERISA. To the extent that state law is applicable, the statutes and common law
of the jurisdiction in which the Executive resides shall apply, excluding any that mandate the use of another jurisdiction’s
laws. The parties irrevocably and unconditionally submit to the jurisdiction and venue of any court, federal or state, situated
within Montgomery County, Texas, for the purpose of any suit, action or other proceeding arising out of, or relating to or in connection
with, the Agreement and this Amendment.

 

5.Acknowledgement.
Executive acknowledges that by entering into this Amendment, Executive is waiving any right Executive may have under the terms
of any existing or future equity award to receive vesting acceleration based solely upon the occurrence of a Change in Control,
provided, that such waiver shall not apply in the event of a Change in Control Cancellation. For the avoidance of doubt, Executive
is only waiving accelerated vesting as provided in the Amendment and Executive’s equity awards shall remain subject to accelerated
vesting upon certain terminations of Executive’s employment as provided in the Employment Agreement (as well as in connection
with any Change in Control Cancellation).

 

6.Miscellaneous.
This Amendment and the Employment Agreement sets forth the entire agreement between the Company and Executive concerning the subject
matter herein, and fully supersedes any and all prior oral or written agreements, promises or understandings between the Company
and Executive concerning the subject matter herein including, without limitation, any acceleration provisions set forth in any
agreement evidencing an equity award held by Executive. Further, Executive represents and acknowledges that in executing this Amendment,
Executive does not rely, and has not relied, on any prior oral or written communications by the Company, and Executive expressly
disclaims any reliance on any prior oral or written communications, agreements, promises, inducements, understandings, statements
or representations in entering into this Amendment. Therefore, Executive understands that he is precluded from bringing any fraud
or fraudulent inducement claim against the Company associated with any such communications, agreements, promises, inducements,
understandings, statements or representations. The Company and Executive are entering into this Amendment based on their own judgment.

IN WITNESS WHEREOF, the Company has caused
this Amendment to be executed by its duly authorized officer and Executive has executed this Amendment as of the Execution Date.
