ARTICLE 2

THE RIGHTS

2.1	Issuance and Evidence of Holdings of Rights

One Right in respect of each Common Share outstanding at the Record Time and each Common Share which may be issued after the Record Time and prior to the earlier of the Separation Time and the Expiration Time shall be issued in accordance with the terms hereof. Notwithstanding the foregoing, one Right in respect of each Common Share issued after the Record Time upon the exercise of rights pursuant to Convertible Securities outstanding at the Record Time may be issued after the Separation Time but prior to the Expiration Time.

Certificates representing Common Shares which are issued after the date of this Agreement but prior to the earlier of the Separation Time and the Expiration Time shall also evidence one Right for each Common Share represented thereby and shall have impressed on, printed on, written on or otherwise affixed to them the following legend:

“Until the Separation Time (as defined in the Shareholder Rights Agreement referred to below), this certificate also evidences and entitles to holder hereof to certain Rights described in a Shareholder Rights Plan Agreement dated as of October 7, 2011 (the “Shareholder Rights Agreement”) between North American Energy Partners Inc. (the “Corporation”) and CIBC Mellon Trust Company (the “Rights Agent”), the terms of which are hereby incorporated herein by reference and a copy of which is on file at the principal executive offices of the Corporation. Under certain circumstances set out in the Shareholder Rights Agreement, the rights may expire, may be amended or redeemed, may become null and void or may be evidenced by separate certificates and no longer evidenced by this certificate. The Corporation will mail or arrange for the mailing of a copy of the Shareholder Rights Agreement to the holder of this certificate without charge as soon as practicable, after the receipt of a written request therefor.”

-24-

Certificates representing Common Shares that are issued and outstanding at the Record Time shall evidence one Right for each Common Share represented thereby, notwithstanding the absence of the foregoing legend, until the close of business on the earlier of the Separation Time and the Expiration Time.

Registered holders of Common Shares who have not received a share certificate and are entitled to do so on the earlier of the Separation Time and the Expiration Time shall be entitled to Rights as if such certificates had been issued and such Rights shall for all purposes hereof be evidenced by the corresponding entries on the Corporation’s securities register for common shares.

2.2	Exercise of Rights; Detachment of Rights

(a)

Subject to adjustment as herein set forth and subject to Section 3.1(1) hereof, each Right will entitle the holder thereof, from and after the Separation Time and prior to the Expiration Time, to purchase one Common Share for the Exercise Price (which Exercise Price and number of Common Shares are subject to adjustment as set forth below). Notwithstanding any other provision of this Agreement, any Rights held by the Corporation or any of its Subsidiaries shall be void.

(b)

Until the Separation Time:

(i)

the Rights shall not be exercisable and no Right may be exercised; and

(ii)

each Right will be evidenced by the certificate for the associated Common Share registered in the name of the holder thereof (which certificate shall also be deemed to represent a Rights Certificate) and will be transferable only together with, and will be transferred by a transfer of, such associated Common Share.

(c)

From and after the Separation Time and prior to the Expiration Time:

(i)

the Rights shall be exercisable; and

(ii)

the registration and transfer of Rights shall be separate from and independent of the Common Shares.

-25-

Promptly following the Separation Time, the Corporation will prepare and the Rights Agent will mail to each holder of record of Common Shares as of the Separation Time (other than an Acquiring Person and, in respect of any Rights Beneficially Owned by such Acquiring Person which are not held of record by such Acquiring Person, the holder of record of such Rights (a “Nominee”)) at such holder’s address as shown by the records of the Corporation (the Corporation hereby agreeing to furnish copies of such records to the Rights Agent for this purpose):

(x)

a Rights Certificate appropriately completed, representing the number of Rights held by such holder at the Separation Time and having such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Corporation may deem appropriate and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any law, rule or regulation or with any rule or regulation of any self-regulatory organization, stock exchange or quotation system on which the Rights may from time to time be listed or traded, or to conform to usage; and

(y)

a disclosure statement describing the Rights,

provided that a Nominee shall be sent the materials provided for in (x) and (y) in respect of all Common Shares held of record by it which are not Beneficially Owned by an Acquiring Person.

(d)

Rights may be exercised, in whole or in part, on any Business Day after the Separation Time and prior to the Expiration Time by submitting to the Rights Agent:

(i)

the Rights Certificate evidencing such Rights;

(ii)

an election to exercise such Rights (an “Election to Exercise”) substantially in the form attached to the Rights Certificate appropriately completed and executed by the holder or his executors or administrators or other personal representatives or his or their legal attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Rights Agent; and

-26-

(iii)

payment by certified cheque, banker’s draft or money order payable to the order of the Rights Agent, of a sum equal to the Exercise Price multiplied by the number of Rights being exercised and a sum sufficient to cover any transfer tax or charge which may be payable in respect of any transfer involved in the transfer or delivery of Rights Certificates or the issuance or delivery of certificates for Common Shares in a name other than that of the holder of the Rights being exercised.

(e)

Upon receipt of a Rights Certificate, together with a duly completed Election to Exercise executed in accordance with Clause 2.2(d)(ii), which does not indicate that such Right is null and void as provided by Subsection 3.1(b), and payment as set forth in Clause 2.2(d)(iii), the Rights Agent (unless otherwise instructed by the Corporation in the event that the Corporation is of the opinion that the Rights cannot be exercised in accordance with this Agreement) will thereupon promptly:

(i)

requisition from the transfer agent for the Common Shares certificates representing the number of such Common Shares to be purchased (the Corporation hereby irrevocably agreeing to authorize its transfer agent to comply with all such requisitions);

(ii)

when appropriate, requisition from the Corporation the amount of cash to be paid in lieu of issuing fractional Common Shares;

(iii)

after receipt of the certificates referred to in Clause 2.2(e)(i), deliver the same to or upon the order of the registered holder of such Rights Certificates, registered in such name or names as may be designated by such holder;

-27-

(iv)

after receipt of the certificates referred to in Clause 2.2(e)(i), deliver any cash referred to in Clause 2.2(e)(ii) to or to the order of the registered holder of such Rights Certificate; and

(v)

tender to the Corporation all payments received on exercise of the Rights.

(f)

In case the holder of any Rights exercises less than all the Rights evidenced by such holder’s Rights Certificate, a new Rights Certificate evidencing the Rights remaining unexercised (subject to the provisions of Subsection 5.6(a)) will be issued by the Rights Agent to such holder or to such holder’s duly authorized assigns.

(g)

The Corporation covenants and agrees that it will:

(i)

take all such action as may be necessary and within its power to ensure that all Common Shares delivered upon exercise of Rights shall, at the time of delivery of the certificates for such Common Shares (subject to payment of the Exercise Price), be duly and validly authorized, executed, issued and delivered and fully paid and non-assessable.

(ii)

take all such actions as may be necessary and within its power to comply with the requirements of the Corporations Act, the Securities Act and the securities laws or comparable legislation of each of the provinces of Canada and any other applicable law, rule or regulation, in connection with the issuance and delivery of the Rights Certificates and the issuance of any Common Shares upon exercise of Rights;

(iii)

use reasonable efforts to cause all Common Shares issued upon exercise of Rights to be listed on the stock exchanges on which such Common Shares were traded immediately prior to the Stock Acquisition Date;

(iv)

cause to be reserved and kept available out of the authorized and unissued Common Shares, the number of Common Shares that, as provided in this Agreement, will from time to time be sufficient to permit the exercise in full of all outstanding Rights;

-28-

(v)

pay when due and payable, if applicable, any and all federal, provincial and municipal transfer taxes and charges (not including any income or capital taxes of the holder or exercising holder or any liability of the Corporation to withhold tax) which may be payable in respect of the original issuance or delivery of the Rights Certificates, or certificates for Common Shares to be issued upon exercise of any Rights, provided that the Corporation shall not be required to pay any transfer tax or charge which may be payable in respect of any transfer involved in the transfer or delivery of Rights Certificates or the issuance or delivery of certificates for Common Shares in a name other than that of the holder of the Rights being transferred or exercised; and

(vi)

after the Separation Time, except as permitted by the provisions hereof, not take (or permit any Subsidiary to take) any action if at the time such action is taken it is reasonably foreseeable that such action will diminish substantially or otherwise eliminate the benefits intended to be afforded by the Rights.

2.3	Adjustments to Exercise Price; Number of Rights

The Exercise Price, the number and kind of securities subject to purchase upon exercise of each Right and the number of Rights outstanding are subject to adjustment from time to time as provided in this Section 2.3.

(a)

In the event the Corporation at any time after the Separation Time and prior to the Expiration Time:

(i)

declares or pays a dividend on Common Shares payable in Common Shares (or capital stock or other securities exchangeable for or convertible into or giving a right to acquire Common Shares or other capital stock) other than pursuant to any optional stock dividend program, dividend reinvestment plan or a dividend payable in Voting Shares in lieu of a regular periodic cash dividend;

-29-

(ii)

subdivides or changes the then outstanding Common Shares into a greater number of Common Shares;

(iii)

consolidates or changes the then outstanding Common Shares into a smaller number of Common Shares; or

(iv)

otherwise issues any Common Shares (or other securities exchangeable for or convertible into or giving a right to acquire Common Shares) in respect of, in lieu of or in exchange for existing Common Shares in a reclassification, amalgamation, merger, statutory arrangement, or consolidation,

the Exercise Price, the number of Rights outstanding and the securities purchasable upon exercise of the Rights shall be adjusted as of the record or effective date as follows:

(x)

the Exercise Price in effect after such adjustment will be equal to the Exercise Price in effect immediately prior to such adjustment divided by the number of Common Shares (the “Expansion Factor”) that a holder of one Common Share immediately prior to such dividend, subdivision, change, consolidation or issuance would hold thereafter as a result thereof (assuming the exercise of any such exchange, conversion or acquisition rights); and

(y)

each Right held prior to such adjustment shall become that number of Rights equal to the Expansion Factor;

and the adjusted number of Rights will be deemed to be allocated among the Common Shares with respect to which the original Rights were associated (if they remain outstanding) and the shares issued in respect of such dividend, subdivision, change, consolidation or issuance, so that each such Common Share will have exactly one Right associated with it.

-30-

To the extent that any such exchange, conversion or acquisition rights are not exercised prior to the expiration thereof, the Exercise Price shall be readjusted to the Exercise Price which would be in effect, based on the number of Common Shares actually issued on the exercise of such rights.

In the event the Corporation at any time after the Record Time and prior to the Separation Time issues any Common Shares (or other securities exchangeable for or convertible into or giving a right to acquire Common Shares), each such Common Share shall automatically have one new Right associated with it, which Right shall be evidenced by the certificate representing such associated Common Share.

(b)

If, after the Record Time and prior to the Separation Time, the Corporation shall issue any shares of capital stock other than Common Shares (or other securities exchangeable for or convertible into or giving a right to acquire shares of any such capital stock) in a transaction of a type described in Clause 2.3(a)(i) or (iv), the shares of such capital stock shall be treated herein as nearly equivalent to Common Shares to the extent practicable and appropriate under the circumstances, as determined by the Board of Directors, and the shares purchasable upon exercise of Rights shall be adjusted as necessary such that the shares purchasable upon exercise of each Right after such adjustment will be the shares that a holder of the shares purchasable upon exercise of one Right immediately prior to such issuance would hold thereafter as a result of such issuance. Notwithstanding Section 5.5, the Corporation and the Rights Agent are authorized and agree to amend this Agreement in order to give effect to the foregoing.

-31-

(c)

In the event that at any time after the Record Time and prior to the Expiration Time there shall occur:

(i)

a reclassification or redesignation of the Common Shares or any change of the Common Shares into other shares (other than as the result of an event described in Subsection 2.3(a));

(ii)

a consolidation, merger or amalgamation of the Corporation with or into another body corporate (other than a consolidation, merger or amalgamation which does not result in a reclassification of the Common Shares or a change of the Common Shares into other shares); or

(iii)

the transfer of all or substantially all of the assets of the Corporation to any other Person;

a holder of a Right shall thereafter be entitled to receive and shall accept upon exercise of such Right, in lieu of the number of Common Shares to which such holder was entitled to acquire upon such exercise, the kind and amount of shares and/or other securities or property which such holder would have been entitled to receive as a result of such occurrence if, on the effective date thereof, such holder had been the holder of the number of Common Shares to which such holder was then entitled upon exercise of such Right. The Corporation shall take all necessary steps so that holders of Rights shall thereafter be entitled to acquire such shares and/or other securities or property, subject to adjustment thereafter in accordance with provisions the same, as nearly as may be possible, as those contained in this Section 2.3.

(d)

Notwithstanding anything herein to the contrary, no adjustment in the Exercise Price shall be required unless such adjustment would require an increase or decrease of at least one percent in the Exercise Price; provided, however, that any adjustments which by reason of this Subsection 2.3(d) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 2.3 shall be made to the nearest cent or to the nearest ten-thousandth of a share. Any adjustment required by this Section 2.3 shall be made no later than the earlier of:

-32-

(i)

three years from the date of the transaction which gives rise to such adjustment; and

(ii)

the Expiration Time.

(e)

Irrespective of any adjustment or change in the Exercise Price or the number of Common Shares issuable upon the exercise of the Rights, the Rights Certificates theretofore and thereafter issued may continue to express the Exercise Price per Common Share and the number of Common Shares which were expressed in the initial Rights Certificates issued hereunder.

(f)

In any case in which this Section 2.3 shall require that an adjustment in the Exercise Price be made effective as of a record date for a specified event, the Corporation may elect to defer until the occurrence of such event the issuance to the holder of any Right exercised after such record date the number of Common Shares and other securities of the Corporation, if any, issuable upon such exercise over and above the number of Common Shares and other securities of the Corporation, if any, issuable upon such exercise on the basis of the Exercise Price in effect prior to such adjustment; provided, however, that the Corporation shall deliver to such holder an appropriate instrument evidencing such holder’s right to receive such additional shares (fractional or otherwise) or other securities upon the occurrence of the event requiring such adjustment.

(g)

Notwithstanding anything contained in this Section 2.3 to the contrary, the Corporation shall be entitled to make such reductions in the Exercise Price, in addition to those adjustments expressly required by this Section 2.3, as and to the extent that in their good faith judgment the Board of Directors shall determine to be advisable, in order that any:

-33-

(i)

consolidation or subdivision of Common Shares;

(ii)

issuance (wholly or in part for cash) of Common Shares or securities that by their terms are convertible into or exchangeable for Common Shares;

(iii)

stock dividends; or

(iv)

issuance of rights, options or warrants, hereafter made by the Corporation to holders of its Common Shares,

shall not be taxable to such shareholders.

(h)

Whenever an adjustment to the Exercise Price or a change in the securities purchasable upon exercise of the Rights is made pursuant to this Section 2.3, the Corporation shall promptly and in any event, where such change or adjustment occurs prior to the Separation Time, not later than the Separation Time:

(i)

file with the Rights Agent and with each transfer agent for the Common Shares a certificate specifying the particulars of such adjustment or change; and

(ii)

cause notice of the particulars of such adjustment or change to be given to the holders of the Rights.

Failure to file such certificate or to cause such notice to be given as aforesaid, or any defect therein, shall not affect the validity of such adjustment or change.

(i)

The Corporation covenants and agrees that, after the Separation Time, it will not, except as permitted by the provisions hereof, take (or permit any Subsidiary of the Corporation to take) any action if at the time such action is taken it is reasonably foreseeable that such action will diminish substantially or otherwise eliminate the benefits intended to be afforded by the Rights.

2.4	Date on Which Exercise Is Effective

Each Person in whose name any certificate for Common Shares or other securities, if applicable, is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the Common Shares or other securities, if applicable, represented thereon, and such certificate shall be dated the date upon which the Rights Certificate evidencing such Rights was duly surrendered in accordance with Subsection 2.2(d) (together with a duly completed Election to Exercise) and payment of the Exercise Price for such Rights (and any applicable transfer taxes and other governmental charges payable by the exercising holder hereunder) was made; provided, however, that if the date of such surrender and payment is a date upon which the Common Share transfer books of the Corporation are closed, such Person shall be deemed to have become the record holder of such shares on, and such certificate shall be dated, the next succeeding Business Day on which the Common Share transfer books of the Corporation are open.

-34-

2.5	Execution, Authentication, Delivery and Dating of Rights Certificates

(a)

The Rights Certificates shall be executed on behalf of the Corporation by its Chief Executive Officer, Chief Financial Officer or any director under the corporate seal of the Corporation reproduced thereon. The signature of any of these individuals on the Rights Certificates may be manual or facsimile. Rights Certificates bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Corporation shall bind the Corporation, notwithstanding that such individuals or any of them have ceased to hold such offices either before or after the countersignature and delivery of such Rights Certificates.

(b)

Promptly after the Corporation learns of the Separation Time, the Corporation will notify the Rights Agent of such Separation Time and will deliver Rights Certificates executed by the Corporation to the Rights Agent for countersignature and disclosure statements describing the Rights, and the Rights Agent shall manually countersign (in a manner satisfactory to the Corporation) and send such Rights Certificates to the holders of the Rights pursuant to Subsection 2.2(c) hereof. No Rights Certificate shall be valid for any purpose until countersigned by the Rights Agent as aforesaid.

(c)

Each Rights Certificate shall be dated the date of countersignature thereof.

-35-

2.6	Registration, Transfer and Exchange

(a)

After the Separation Time, the Corporation will cause to be kept a register (the “Rights Register”) in which, subject to such reasonable regulations as it may prescribe, the Corporation will provide for the registration and transfer of Rights. The Rights Agent is hereby appointed registrar for the Rights (the “Rights Registrar”) for the purpose of maintaining the Rights Register for the Corporation and registering Rights and transfers of Rights as herein provided and the Rights Agent hereby accepts such appointment. In the event that the Rights Agent shall cease to be the Rights Registrar, the Rights Agent will have the right to examine the Rights Register at all reasonable times.

After the Separation Time and prior to the Expiration Time, upon surrender for registration of transfer or exchange of any Rights Certificate, and subject to the provisions of Subsection 2.6(c), the Corporation shall execute, and the Rights Agent shall manually countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder’s instructions, one or more new Rights Certificates evidencing the same aggregate number of Rights as did the Rights Certificates so surrendered.

(b)

All Rights issued upon any registration of transfer or exchange of Rights Certificates shall be the valid obligations of the Corporation, and such Rights shall be entitled to the same benefits under this Agreement as the Rights surrendered upon such registration of transfer or exchange.

(c)

Every Rights Certificate surrendered for registration of transfer or exchange shall be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Corporation or the Rights Agent, as the case may be, duly executed by the holder thereof or such holder’s attorney duly authorized in writing. As a condition to the issuance of any new Rights Certificate under this Section 2.6, the Corporation or the Rights Agent may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the reasonable fees and expenses of the Rights Agent) connected therewith.

-36-

2.7	Mutilated, Destroyed, Lost and Stolen Rights Certificates

(a)

If any mutilated Rights Certificate is surrendered to the Rights Agent prior to the Expiration Time, the Corporation shall execute and the Rights Agent shall countersign and deliver in exchange therefor a new Rights Certificate evidencing the same number of Rights as did the Rights Certificate so surrendered.

(b)

If there shall be delivered to the Corporation and the Rights Agent prior to the Expiration Time:

(i)

evidence to their reasonable satisfaction of the destruction, loss or theft of any Rights Certificate; and

(ii)

such security or indemnity as may be reasonably required by each of them in their sole discretion to save each of them and any of their agents harmless;

then, in the absence of notice to the Corporation or the Rights Agent that such Rights Certificate has been acquired by a bona fide purchaser, the Corporation shall execute and upon the Corporation’s request the Rights Agent shall countersign and deliver, in lieu of any such destroyed, lost or stolen Rights Certificate, a new Rights Certificate evidencing the same number of Rights as did the Rights Certificate so destroyed, lost or stolen.

(c)

As a condition to the issuance of any new Rights Certificate under this Section 2.7, the Corporation or the Rights Agent may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the reasonable fees and expenses of the Rights Agent) connected therewith.

-37-

(d)

Every new Rights Certificate issued pursuant to this Section 2.7 in lieu of any destroyed, lost or stolen Rights Certificate shall evidence an original additional contractual obligation of the Corporation, whether or not the destroyed, lost or stolen Rights Certificate shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Agreement equally and proportionately with any and all other Rights, duly issued hereunder.

2.8	Persons Deemed Owners of Rights

The Corporation, the Rights Agent and any agent of the Corporation or the Rights Agent may deem and treat the Person, in whose name a Rights Certificate (or, prior to the Separation Time, the associated Common Share certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby for all purposes whatsoever. In this Agreement, unless the context otherwise requires, the term “holder” of any Right means the registered holder of such Right (or, prior to the Separation Time, the associated Common Share).

2.9	Delivery and Cancellation of Certificates

All Rights Certificates surrendered upon exercise or for redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Rights Agent, be delivered to the Rights Agent and, in any case, shall be promptly cancelled by the Rights Agent. The Corporation may at any time deliver to the Rights Agent for cancellation any Rights Certificates previously countersigned and delivered hereunder which the Corporation may have acquired in any manner whatsoever, and all Rights Certificates so delivered shall be promptly cancelled by the Rights Agent. No Rights Certificate shall be countersigned in lieu of or in exchange for any Rights Certificates cancelled as provided in this Section 2.9, except as expressly permitted by this Agreement. The Rights Agent shall, subject to applicable laws, destroy all cancelled Rights Certificates and deliver a certificate of destruction to the Corporation on request.

-38-

2.10	Agreement of Rights Holders

Every holder of Rights, by accepting the same, consents and agrees with the Corporation and the Rights Agent and with every other holder of Rights that:

(a)

such holder of Rights shall be bound by and subject to the provisions of this Agreement, as amended from time to time in accordance with the terms hereof, in respect of all Rights held;

(b)

prior to the Separation Time, each Right will be transferable only together with, and will be transferred by a transfer of, the associated Common Share certificate representing such Right;

(c)

after the Separation Time, the Rights Certificates will be transferable only on the Rights Register as provided herein;

(d)

prior to due presentment of a Rights Certificate (or, prior to the Separation Time, the associated Common Share certificate) for registration of transfer, the Corporation, the Rights Agent and any agent of the Corporation or the Rights Agent may deem and treat the Person in whose name the Rights Certificate (or, prior to the Separation Time, the associated Common Share certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or writing on such Rights Certificate or the associated Common Share certificate made by anyone other than the Corporation or the Rights Agent) for all purposes whatsoever, and neither the Corporation nor the Rights Agent shall be affected by any notice to the contrary;

(e)

such holder of Rights has waived his right to receive any fractional Rights or any fractional shares or other securities upon exercise of a Right (except as provided herein);

-39-

(f)

subject to the provisions of Section 5.5, without the approval of any holder of Rights or Voting Shares and upon the sole authority of the Board of Directors, this Agreement may be supplemented or amended from time to time to cure any ambiguity or to correct or supplement any provision contained herein which may be inconsistent with the intent of this Agreement or is otherwise defective, as provided here; and

(g)

notwithstanding anything in this Agreement to the contrary, neither the Corporation nor the Rights Agent shall have any liability to any holder of a Right or any other Person as a result of its inability to perform any of its obligations under this Agreement by reason of any preliminary or permanent injunction or other order, decree or ruling issued by a court of competent jurisdiction or by a governmental, regulatory or administrative agency or commission, or any statute, rule, regulation or executive order promulgated or enacted by any governmental authority, prohibiting or otherwise restraining performance of such obligation.

2.11	Rights Certificate Holder Not Deemed a Shareholder

No holder, as such, of any Rights or Rights Certificate shall be entitled to vote, receive dividends or be deemed for any purpose whatsoever the holder of any Common Share or any other share or security of the Corporation which may at any time be issuable on the exercise of the Rights represented thereby, nor shall anything contained herein or in any Rights Certificate be construed or deemed or confer upon the holder of any Right or Rights Certificate, as such, any right, title, benefit or privilege of a holder of Common Shares or any other shares or securities of the Corporation or any right to vote at any meeting of shareholders of the Corporation whether for the election of directors or otherwise or upon any matter submitted to holders of Common Shares or any other shares of the Corporation at any meeting thereof, or to give or withhold consent to any action of the Corporation, or to receive notice of any meeting or other action affecting any holder of Common Shares or any other shares of the Corporation except as expressly provided herein, or to receive dividends, distributions or subscription rights, or otherwise, until the Right or Rights evidenced by Rights Certificates shall have been duly exercised in accordance with the terms and provisions hereof.

-40-

ARTICLE 3

ADJUSTMENTS TO THE RIGHTS IN THE EVENT OF CERTAIN TRANSACTIONS

3.1	Flip-in Event

(a)

Subject to Subsection 3.1(b) and Sections 5.1 and 5.2, in the event that prior to the Expiration Time a Flip-in Event shall occur, the Corporation shall take such action as shall be necessary to ensure and provide, within 10 Business Days thereafter or such longer period as may be required to satisfy the requirements of applicable securities laws or comparable legislation so that, except as provided below, each Right shall thereafter constitute the right to purchase from the Corporation, upon exercise thereof in accordance with the terms hereof, that number of Common Shares having an aggregate Market Price on the date of consummation or occurrence of such Flip-in Event equal to twice the Exercise Price for an amount in cash equal to the Exercise Price (such right to be appropriately adjusted in a manner analogous to the applicable adjustment provided for in Section 2.3 in the event that after such occurrence, an event of a type analogous to any of the events described in Section 2.3 shall have occurred).

(b)

Notwithstanding anything in this Agreement to the contrary, upon the occurrence of any Flip-in Event, any Rights that are or were Beneficially Owned on or after the earlier of the Separation Time or the Stock Acquisition Date by:

(i)

an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly or in concert with an Acquiring Person or any Affiliate or Associate of an Acquiring Person); or

(ii)

a transferee of Rights, directly or indirectly, from an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly or in concert with an Acquiring Person or any Affiliate or Associate of an Acquiring Person), where such transferee becomes a transferee concurrently with or subsequent to the Acquiring Person becoming such in a transfer that the Board of Directors has determined is part of a plan, understanding or scheme of an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly or in concert with an Acquiring Person or any Affiliate or Associate of an Acquiring Person), that has the purpose or effect of avoiding this Clause 3.1(b),

-41-

shall become null and void without any further action, and any holder of such Rights (including transferees) shall thereafter have no right to exercise such Rights under any provision of this Agreement and further shall thereafter not have any other rights whatsoever with respect to such Rights, whether under any provision of this Agreement or otherwise.

(c)

Any Rights Certificate that represents Rights Beneficially Owned by a Person described in either Clause 3.1(b)(i) or (ii) or transferred to any nominee of any such Person, and any Rights Certificate issued upon the transfer, exchange, replacement or adjustment of any other Rights Certificate referred to in this sentence, shall contain the following legend:

ARTICLE 4

THE RIGHTS AGENT

4.1

General

(a)

The Corporation hereby appoints the Rights Agent to act as agent for the Corporation and the holders of the Rights in accordance with the terms and conditions hereof, and the Rights Agent hereby accepts such appointment. The Corporation may from time to time appoint such co-Rights Agents (the “Co-Rights Agents”) as it may deem necessary or desirable. In the event the Corporation appoints one or more Co-Rights Agents, the respective duties of the Rights Agent and Co-Rights Agents shall be as the Corporation may determine, subject to the reasonable consent of the Rights Agent. The Corporation agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses (including fees and disbursements of counsel) and other disbursements reasonably incurred in the execution and administration of this Agreement and the exercise and performance of its duties hereunder, with the prior approval of the Corporation. The Corporation will fully indemnify and hold the Rights Agent, its officers, directors, employees and agents harmless from and against any and all losses, damages, costs, charges, counsel fees, payments, expenses and liabilities arising directly or indirectly out of its agency relationship to the Corporation as set forth in this Agreement (which right to indemnification will survive the termination of this Agreement or the resignation or removal of the Rights Agent) except for any liability arising out of the negligence or intentional misconduct by the Rights Agent. In the absence of negligence or intentional misconduct on its part, the Rights Agent shall not be liable for any action taken, suffered, omitted by it or for any error of judgement made by it in good faith in the performance of its duties under this Agreement. In no event will the Rights Agent be liable for special, indirect, consequential or punitive loss or damages of any kind whatsoever (including but not limited to lost profits), even if the Rights Agent has been advised of the possibility of such damages.

(b)

The Rights Agent shall be protected and shall incur no liability for or in respect of any action taken, suffered or omitted by it in connection with its administration of this Agreement in reliance upon any certificate for Common Shares, Rights Certificate, certificate for other securities of the Corporation, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, statement, or other paper or document believed by it to be genuine and to be signed, executed and, where necessary, verified or acknowledged, by the proper Person or Persons.

-43-

(c)

The Corporation shall inform the Rights Agent in a reasonably timely manner of events which may materially affect the administration of this Agreement by the Rights Agent and, at any time upon request shall provide to the Rights Agent an incumbency certificate certifying the then current officers of the Corporation.

4.2	Merger, Amalgamation or Consolidation or Change of Name of Rights Agent

(a)

Any corporation into which the Rights Agent may be merged or amalgamated or with which it may be consolidated, or any corporation resulting from any merger, amalgamation, statutory arrangement or consolidation to which the Rights Agent or any successor Rights Agent is a party, or any corporation succeeding to the shareholder or stockholder services business of the Rights Agent or any successor Rights Agent, will be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such corporation would be eligible for appointment as a successor Rights Agent under the provisions of Section 4.4 hereof. In case, at the time such successor Rights Agent succeeds to the agency created by this Agreement, any of the Rights Certificates have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of the predecessor Rights Agent and deliver such Rights Certificates so countersigned; and in case at that time any of the Rights have not been countersigned, any successor Rights Agent may countersign such Rights Certificates in the name of the predecessor Rights Agent or in the name of the successor Rights Agent; and in all such cases such Rights Certificates will have the full force provided in the Rights Certificates and in this Agreement.

(b)

In case at any time the name of the Rights Agent is changed and at such time any of the Rights Certificates shall have been countersigned but not delivered, the Rights Agent may adopt the countersignature under its prior name and deliver Rights Certificates so countersigned; and in case at that time any of the Rights Certificates shall not have been countersigned, the Rights Agent may countersign such Rights Certificates either in its prior name or in its changed name; and in all such cases such Rights Certificates shall have the full force provided in the Rights Certificates and in this Agreement.

-44-

4.3	Duties of Rights Agent

The Rights Agent undertakes the duties and obligations imposed by this Agreement upon the following terms and conditions, all of which the Corporation and the holders of certificates for Common Shares and the holders of Rights Certificates, by their acceptance thereof, shall be bound:

(a)

the Rights Agent may retain and consult with legal counsel (who may be legal counsel for the Corporation) and the opinion of such counsel will be full and complete authorization and protection to the Rights Agent as to any action taken or omitted by it in good faith and in accordance with such opinion; the Rights Agent may also, with the prior approval of the Corporation, consult with such other experts as the Rights Agent shall consider necessary or appropriate to properly carry out the duties and obligations imposed under this Agreement;

(b)

whenever in the performance of its duties under this Agreement, the Rights Agent deems it necessary or desirable that any fact or matter be proved or established by the Corporation prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by a Person believed by the Rights Agent to be the Chief Executive Officer, Chief Financial Officer or any director of the Corporation and delivered to the Rights Agent, and such certificate will be full authorization to the Rights Agent for any action taken or suffered in good faith by it under the provisions of this Agreement in reliance upon such certificate;

-45-

(c)

the Rights Agent will be liable hereunder for its own negligence, bad faith or intentional misconduct;

(d)

the Rights Agent will not be liable for or by reason of any of the statements of fact or recitals contained in this Agreement or in the certificates for Common Shares or the Rights Certificates (except its countersignature thereof) or be required to verify the same, but all such statements and recitals are and will be deemed to have been made by the Corporation only;

(e)

the Rights Agent will not be under any responsibility in respect of the validity of this Agreement or the execution and delivery hereof (except the due authorization, execution and delivery hereof by the Rights Agent) or in respect of the validity or execution of any certificate for a Common Share or Rights Certificate (except its countersignature thereof); nor will it be responsible for any breach by the Corporation of any covenant or condition contained in this Agreement or in any Rights Certificate; nor will it be responsible for any change in the exercisability of the Rights (including the Rights becoming void pursuant to Subsection 3.1(b) hereof) or any adjustment required under the provisions of Section 2.3 hereof or responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment (except with respect to the exercise of Rights after receipt of the certificate contemplated by Section 2.3 describing any such adjustment); nor will it by any act hereunder be deemed to make any representation or warranty as to the authorization of any Common Shares to be issued pursuant to this Agreement or any Rights or as to whether any Common Shares will, when issued, be duly and validly authorized, executed, issued and delivered and fully paid and non-assessable;

-46-

(f)

the Corporation agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Rights Agent for the carrying out or performing by the Rights Agent of the provisions of this Agreement;

(g)

the Rights Agent is hereby authorized and directed to accept instructions in writing with respect to the performance of its duties hereunder from any individual believed by the Rights Agent to be the Chief Executive Officer, Chief Financial Officer or any director of the Corporation, and to apply to such individuals for advice or instructions in connection with its duties, and it shall not be liable for any action taken or suffered by it in good faith in accordance with instructions of any such individual;

(h)

the Rights Agent and any shareholder, director, officer or employee of the Rights Agent may buy, sell or deal in Common Shares, Rights or other securities of the Corporation or become pecuniarily interested in any transaction in which the Corporation may be interested, or contract with or lend money to the Corporation or otherwise act as fully and freely as though it were not Rights Agent under this Agreement;

(i)

nothing herein shall preclude the Rights Agent from acting in any other capacity for the Corporation or for any other legal entity; and

(j)

the Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys or agents, and the Rights Agent will not be answerable or accountable for any act, default, neglect or misconduct of any such attorneys or agents or for any loss to the Corporation resulting from any such act, default, neglect or misconduct, provided reasonable care was exercised in the selection and continued employment thereof.

-47-

4.4	Change of Rights Agent

The Rights Agent may resign and be discharged from its duties under this Agreement upon 60 days’ notice (or such lesser notice as is acceptable to the Corporation) in writing mailed to the Corporation and to each transfer agent of Common Shares by registered or certified mail. The Corporation may remove the Rights Agent upon 30 days’ notice in writing, mailed to the Rights Agent and to each transfer agent of the Common Shares by registered or certified mail. If the Rights Agent should resign or be removed or otherwise become incapable of acting, the Corporation will appoint a successor to the Rights Agent. If the Corporation fails to make such appointment within a period of 30 days after such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent, then by prior written notice to the Corporation the resigning Rights Agent at the Corporation’s expense or the holder of any Rights (which holder shall, with such notice, submit such holder’s Rights Certificate, if any, for inspection by the Corporation), may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Corporation or by such a court, shall be a corporation incorporated under the laws of Canada or a province thereof authorized to carry on the business of a trust company in the province of Ontario. After appointment, the successor Rights Agent will be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent shall, following payment of all outstanding fees and expenses owed to it under this Agreement, deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Corporation will file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Shares and mail a notice thereof in writing to the holders of the Rights in accordance with Section 5.11. Failure to give any notice provided for in this Section 4.4, however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of any successor Rights Agent, as the case may be.

-48-

4.5	Compliance with Anti-Money Laundering Legislation

The Rights Agent shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Rights Agent reasonably determines that such an act might cause it to be in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline. Further, should the Rights Agent reasonably determine at any time that its acting under this Agreement has resulted in it being in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline, then it shall have the right to resign on 10 days’ prior written notice to the Corporation, provided: (i) that the Rights Agent’s written notice shall describe the circumstances of such non-compliance; and (ii) that if such circumstances are rectified to the Rights Agent’s satisfaction within such 10 day period, then such resignation shall not be effective.

may, at any time prior to Separation Time, subject to receipt of Shareholder Approval, or

(ii)

may, at any time after the Separation Time, subject to receipt of the consent of holders of Rights given in accordance with Section 5.5,

elect to redeem all but not less than all of the then outstanding Rights at a redemption price of $0.00001 per Right, appropriately adjusted in a manner analogous to the applicable adjustment provided for in Section 2.3, if an event of the type analogous to any of the events described in Section 2.3 shall have occurred (such redemption price being herein referred to as the “Redemption Price”).

-49-

(b)

If a Person acquires, pursuant to a Permitted Bid or a Competing Permitted Bid or pursuant to an Exempt Acquisition occurring under Subsection 5.2(b) hereof, outstanding Voting Shares, the Board of Directors of the Corporation shall, immediately upon such acquisition and without further formality, be deemed to have elected to redeem the Rights at the Redemption Price.

(c)

Where a Take-over Bid that is not a Permitted Bid or Competing Permitted Bid expires, is withdrawn or otherwise terminated after the Separation Time has occurred and prior to the occurrence of a Flip-in Event, the Board of Directors may elect to redeem all of the outstanding Rights at the Redemption Price.

(d)

If the Board of Directors elects to or is deemed to have elected to redeem the Rights (i) the right to exercise the Rights will thereupon, without further action and without notice, terminate and the only right thereafter of the holders of Rights shall be to receive the Redemption Price, and (ii) subject to Subsection 5.1(f), no further Rights shall thereafter be issued.

(e)

Within 10 Business Days of the Board of Directors electing or having been deemed to have elected to redeem the Rights, the Corporation shall give notice of redemption to the holders of the then outstanding Rights by mailing such notice to each such holder at his last address as it appears upon the Rights Register of the Rights Agent, or, prior to the Separation Time, on the share register maintained by the Corporation’s transfer agent or transfer agents. Each such notice of redemption shall state the method by which the payment of the Redemption Price shall be made.

5.2	Waiver of Flip-In Events

(a)

The Board of Directors, may, at any time prior to the occurrence of a Flip-in Event that would occur by reason of an acquisition of Voting Shares or Convertible Securities otherwise than pursuant to a Take-over Bid made by means of a take-over bid circular to all holders of Voting Shares or otherwise than in the circumstances set forth in Subsection 5.2(c) and subject to receipt of Shareholder Approval, waive the application of Section 3.1 to such Flip-in Event by written notice delivered to the Rights Agent.

(b)

The Board of Directors may, at any time prior to the occurrence of a Flip-in Event that would occur as a result of a Take-over Bid made by way of a take-over bid circular sent to all holders of Voting Shares, waive the application of Section 3.1 to such Flip-in Event by written notice delivered to the Rights Agent provided, however, that if the Board of Directors waives the application of Section 3.1 to such a Flip-in Event, the Board of Directors shall be deemed to have waived the application of Section 3.1 to any other Flip-in Event occurring by reason of any Takeover Bid that is made by means of a take-over bid circular to all holders of Voting Shares prior to the expiry of any Take-over Bid in respect of which a waiver is, or is deemed to have been, granted under this Subsection 5.2(b).

-54-

5.6	Fractional Rights and Fractional Shares

(a)

The Corporation shall not be required to issue fractions of Rights or to distribute Rights Certificates which evidence fractional Rights. After the Separation Time, in lieu of issuing fractional Rights, the Corporation shall pay to the holders of record of the Rights Certificates (provided the Rights represented by such Rights Certificates are not void pursuant to the provisions of Subsection 3.1(b), at the time such fractional Rights would otherwise be issuable), an amount in cash equal to the fraction of the Market Price of one whole Right that the fraction of a Right that would otherwise be issuable is of one whole Right.

5.7	Rights of Action

Subject to the terms of this Agreement, all rights of action in respect of this Agreement, other than rights of action vested solely in the Rights Agent, are vested in the respective holders of the Rights.

Without limiting the foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holders of Rights would not have an adequate remedy at law for any breach of this Agreement and will be entitled to specific performance of the obligations under, and injunctive relief against actual or threatened violations of the obligations of any Person subject to, this Agreement.

-55-

5.8	Regulatory Approvals

Any obligation of the Corporation or action or event contemplated by this Agreement shall be subject to the receipt of any requisite approval or consent from any governmental or regulatory authority. Without limiting the generality of the foregoing, any issuance of or delivery of debt or equity securities (other than non-convertible debt securities) of the Corporation upon the exercise of Rights and any amendment or supplement to this Agreement shall be subject to the prior written consent of the Toronto Stock Exchange and any other exchange upon which the Common Shares may be listed.

5.9	Declaration as to Non-Canadian Holders

If in the opinion of the Board of Directors (who may rely upon the advice of counsel) any action or event contemplated by this Agreement would require compliance by the Corporation with the securities laws or comparable legislation of a jurisdiction outside Canada, the Board of Directors acting in good faith shall take such actions as it may deem appropriate to ensure such compliance. In no event shall the Corporation or the Rights Agent be required to issue or deliver Rights or securities issuable on exercise of Rights to Persons who are citizens, residents or nationals of any jurisdiction other than Canada, in which such issue or delivery would be unlawful without registration of the relevant Persons or securities for such purposes. If it would be necessary in any jurisdiction other than Canada to register any of the Rights or securities issuable on exercise of Rights prior to such issue or delivery, the Corporation will use its best efforts to establish procedures whereby shareholders entitled to such Rights, or holders of Rights entitled to securities upon the exercise of Rights, will have the ability to trade or exercise such Rights, or and be issued such securities, without the need to register those securities in the jurisdiction in which they reside, through the establishment of a trustee to hold and sell such securities in Canada, or such other mechanism as the Board of Directors believes is appropriate.

-56-

5.10	Privacy Legislation

The parties acknowledge that federal and/or provincial legislation that addresses the protection of individual’s personal information (collectively, “Privacy Laws”) applies to obligations and activities under this Agreement. Despite any other provision of this Agreement, neither party will take or direct any action that would contravene, or cause the other to contravene, applicable Privacy Laws. The Corporation will, prior to transferring or causing to be transferred personal information to the Rights Agent, obtain and retain required consents of the relevant individuals to the collection, use and disclosure of their personal information, or will have determined that such consents either have previously been given upon which the parties can rely or are not required under the Privacy Laws. The Rights Agent will use commercially reasonable efforts to ensure that its services hereunder comply with Privacy Laws.

THE RIGHTS ARE SUBJECT TO TERMINATION ON THE TERMS SET FORTH IN THE SHAREHOLDER RIGHTS PLAN AGREEMENT. UNDER CERTAIN CIRCUMSTANCES (SPECIFIED IN SUBSECTION 3.1(b) OF THE SHAREHOLDER RIGHTS PLAN AGREEMENT), RIGHTS BENEFICIALLY OWNED BY AN ACQUIRING PERSON OR CERTAIN RELATED PARTIES OR TRANSFEREES OF AN ACQUIRING PERSON OR CERTAIN RELATED PARTIES, MAY BECOME VOID.

Rights Certificate

This certifies that, or registered assigns, is the registered holder of the number of Rights set forth above, each of which entitles the registered holder thereof, subject to the terms, provisions and conditions of the Shareholder Rights Plan Agreement, dated as of October 7, 2011, as the same may be amended or supplemented from time to time (the “Shareholder Rights Agreement”), between North American Energy Partners Inc., a corporation existing under the laws of Canada (the “Corporation”) and CIBC Mellon Trust Company, a company existing under the laws of Canada (the “Rights Agent”) (which term shall include any successor Rights Agent under the Shareholder Rights Agreement), to purchase from the Corporation at any time after the Separation Time (as such term is defined in the Shareholder Rights Agreement) and prior to the Expiration Time (as such term is defined in the Shareholder Rights Agreement), one fully paid common share of the Corporation (a “Common Share”) at the Exercise Price referred to below, upon presentation and surrender of this Rights Certificate with the Form of Election to Exercise (in the form provided hereinafter) duly executed and submitted to the Rights Agent at its principal office in the City of Calgary. The Exercise Price shall be an amount expressed in Canadian dollars equal to five times the Market Price (as such term is defined in the Shareholder Rights Agreement) per Common Share at the Separation Time, subject to adjustment in certain events as provided in the Shareholder Rights Agreement.

This Rights Certificate is subject to all of the terms and provisions of the Shareholder Rights Agreement, which terms and provisions are incorporated herein by reference and made a part hereof and to which Shareholder Rights Agreement reference is hereby made for a full description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Rights Agent, the Corporation and the holders of the Rights Certificates. Copies of the Shareholder Rights Agreement are on file at the registered office of the Corporation.

This Rights Certificate, with or without other Rights Certificates, upon surrender at any of the offices of the Rights Agent designated for such purpose, may be exchanged for another Rights Certificate or Rights Certificates of like tenor and date evidencing an aggregate number of Rights equal to the aggregate number of Rights evidenced by the Rights Certificate or Rights Certificates surrendered. If this Rights Certificate shall be exercised in part, the registered holder shall be entitled to receive, upon surrender hereof, another Rights Certificate or Rights Certificates for the number of whole Rights not exercised.

Subject to the provisions of the Shareholder Rights Agreement, the Rights evidenced by this Rights Certificate may be, and under certain circumstances are required to be, redeemed by the Corporation at a redemption price set out in the Shareholder Rights Agreement.

No fractional Common Shares will be issued upon the exercise of any Rights evidenced hereby, but in lieu thereof a cash payment will be made, as provided in the Shareholder Rights Agreement.

No holder of this Rights Certificate, as such, shall be entitled to vote or receive dividends or be deemed for any purpose the holder of Common Shares or of any other securities which may at any time be issuable upon the exercise hereof; nor shall anything contained in the Shareholder Rights Agreement or herein be construed to confer upon the holder hereof, as such, any of the rights of a shareholder of the Corporation or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting shareholders (except as provided in the Shareholder Rights Agreement), or to receive dividends or subscription rights, or otherwise, until the Rights evidenced by this Rights Certificate shall have been exercised as provided in the Shareholder Rights Agreement.
