ADDITIONAL INFORMATION REGARDING THE MEETING

We will hold the Meeting in Quesnel, B.C. Additionally, a live-webcast option will be provided to Shareholders to listen in and view the Meeting and ask questions. Shareholders will be able to access the live-webcast will at https://web.lumiagm.com/433290564, password “westfraser2023” (case sensitive), where they can listen in and view the Meeting and ask questions.

Registered Shareholders and duly appointed proxyholders (including Non-registered Shareholders who have duly appointed themselves as proxyholder) will have a live-webcast option where they can listen in and view the Meeting and ask questions, provided they are connected to the Internet and follow the instructions in this Circular. Non-registered Shareholders who have not duly appointed themselves as proxyholder will be able to use the live-webcast option as guests but will not be able to ask questions.

Shareholders who wish to appoint a person other than the management nominees identified in the form of proxy or voting instruction form (including a Non-registered Shareholder who wishes to appoint themselves as their own proxy to use the live webcast) must carefully follow the instructions set out in this Circular and on their form of proxy or voting instruction form. These instructions include the additional step of registering such proxyholder with Computershare, after submitting the form of proxy or voting instruction form. Failure to register the proxyholder with Computershare will result in the proxyholder not receiving a 15-digit control number required to ask questions in the Meeting, which would only allow the proxyholder to attend the Meeting as a guest. Guests will be able only to listen to the Meeting but will not be able to ask questions.

Your vote is important. Good corporate governance begins with Shareholder participation. If you cannot attend the Meeting or if you plan to attend but prefer the convenience of voting in advance, we encourage you to exercise your vote using either of the voting methods described below. Please read pages 7 through 14 for answers to commonly asked questions regarding voting and proxies.

How to Vote

You have two ways to vote:

1. you may vote in person at the Meeting; or

2. by submitting your form of proxy or voting instruction form in accordance with the instructions set out therein.

If a Registered Shareholder is a body corporate or association, the form of proxy must be signed by a person duly authorized by that body corporate or association. Completing, signing and returning a form of proxy will not prevent you from attending the Meeting in person. As the Company is relying on notice and access provisions of applicable Canadian securities laws, the Notice and form of proxy is being sent to Registered Shareholders.

How to Ask Questions at the Meeting

Shareholders will have an opportunity to ask questions in person and online (as applicable) by following the procedures set out below.

1. Registered Shareholders and proxyholders (including Non-registered Shareholders who have duly appointed themselves as proxyholder) attending the Meeting in person will have an opportunity to ask questions at the Meeting during the Q&A session.

6

2. Registered Shareholders and proxyholders (including Non-registered Shareholders who have duly appointed themselves as proxyholder) following the Meeting online will have an opportunity to ask questions through the webcast platform. To do so, they will need to obtain a control number by following the instructions provided below. Once they have registered and obtained a control number and are logged into the online platform, they should select the messaging icon and type the question within the chat box at the bottom of the messaging screen. Once satisfied with the question, the Shareholder or proxyholder should click the arrow button to submit the question to the Chair of the Meeting. All submitted questions will be moderated before being sent to the Chair of the Meeting. Questions can be submitted at any time during the Q&A session up until the Chair of the Meeting closes the session.

It is anticipated that Shareholders will have substantially the same opportunity to ask questions online on matters of business during the Meeting as if they attend the Meeting in person.

How Shareholders and appointees can obtain a control number to ask questions during the Meeting

● Registered Shareholders: Registered Shareholders can find their control number on their proxy form.

● Non-registered Shareholders and Appointees: Non-registered Shareholders and duly appointed proxyholders must complete the additional step of registering as a proxyholder by calling Computershare at 1-800-564-6253 (North American toll free) or 1-514-982-7555 (International) by no later than 11:30 a.m. (Vancouver time) on April 14, 2023. Non-registered Shareholders and proxyholders who have not appointed themselves as proxyholder will not receive a control number, which is required to ask questions at the Meeting.

Non-registered Shareholders who have not duly appointed themselves as proxyholder and registered with Computershare will not be able to ask questions at the Meeting but will be able to follow the proceedings as a guest.

Technical Assistance

Shareholders with questions regarding the live-webcast platform or requiring assistance accessing the Meeting website should visit the provider’s website at https://www.lumiglobal.com/faq. Furthermore, should a Shareholder wish to speak with a Computershare representative concerning the live-webcast, both a live chat service and a contact ticket system are available through the website above.

If you are accessing the Meeting using the live-webcast, you must remain connected to the Internet at all times during the Meeting in order to listen in, view the Meeting and ask questions. It is your responsibility to ensure Internet connectivity for the duration of the Meeting. Note that if you lose connectivity once the Meeting has commenced, there may be insufficient time to resolve your issue before the Meeting is completed.

FREQUENTLY ASKED QUESTIONS

Q. Am I entitled to vote?

A.      Holders of Shares at the close of business on the Record Date of February 28, 2023 and their duly appointed representatives are eligible to vote. Each Share is entitled to one vote.

Q. How do I vote?

A.      If you are a Registered Shareholder, you may vote your Shares by appointing a proxyholder to attend the Meeting and vote on your behalf. Voting by proxy is the easiest way to vote because you do not have to attend the Meeting. Instead, you appoint the persons named in the form of proxy or another person or entity of your choosing, who need not be a Shareholder, to represent you as a proxyholder and vote your Shares at the Meeting. A proxy will not be valid unless it is dated and signed by the Registered Shareholder or by the Registered Shareholder’s attorney with proof that they are authorized to sign, and is completed according to the instructions therein.

There are different ways to submit your voting instructions depending on whether you are a Registered Shareholder or a Non-registered Shareholder. If your Shares are held in an account with a bank, trust company, securities broker, trustee or other intermediary, please refer to “Voting by Non-registered Shareholders”.

See “How to Vote” for further details on how to vote.

Q. What am I voting on?

A. You will be asked to vote on the following matters:

● fixing the number of Directors at 11;

● the election of Directors to hold office until the close of the next annual meeting of Shareholders;

● the appointment of PricewaterhouseCoopers LLP as our auditor until the close of the next annual meeting of Shareholders, at a remuneration to be fixed by the Directors;

● the advisory (non-binding) resolution on the Company’s approach to executive compensation; and

● the amendment, restatement and continuation of the Company’s Shareholder Rights Plan.

Q. What if amendments are made to these matters or if other matters are brought before the Meeting?

A.      If you attend the Meeting and are eligible to vote, you may vote on such matters as you choose.

If you have completed and returned a proxy in the form enclosed, the persons named in it will have discretionary authority with respect to amendments or variations to matters identified in the Notice and to other matters which properly come before the Meeting. If any other matter properly comes before the Meeting, the persons so named will vote on it in accordance with their best judgment. As of the date of this

8

Circular, our management does not know of any such amendment, variation or other matter expected to come before the Meeting.

Q. Who is soliciting my proxy?

A.      The management of West Fraser is soliciting your proxy. Solicitation of proxies is done primarily by mail, supplemented by telephone or other contact, by Company employees, and the Company bears all associated costs.

This Circular is prepared under the notice and access rules that came into effect on February 11, 2013 pursuant to applicable Canadian securities laws. Accordingly, this Circular is being posted on the Internet instead of being mailed to either Registered Shareholders or Non-registered Shareholders. This Circular and related proxy materials are available under the Company’s profile on SEDAR at www.sedar.com and on EDGAR at www.sec.gov/edgar.shtml, and on the Company’s website at www.westfraser.com/. Shareholders are reminded to review these materials online in connection with the Meeting and before voting. Shareholders may obtain a physical copy of this Circular by: (a) calling Computershare, toll free at 1-800-564-6253 (North American toll free) or 1-514-982-7555 (International); or (b) emailing a request to Computershare at service@computershare.com. A request for a physical copy of this Circular should be sent sufficiently in advance so that it is received by Computershare by April 4, 2023 in order to allow sufficient time for the Shareholder to receive the physical copy of this Circular and return the proxy by its due date.

Q. How do I know if I am a “Registered” Shareholder or a “Non-registered” Shareholder?

A.      You may own Shares in one or both of the following ways:

1.      If you are in possession of a physical share certificate in your name or you appear as the Registered Shareholder in the records of Computershare, you are a “Registered Shareholder” and your name and address are known to West Fraser through Computershare.

2.      If you own Shares through a bank, trust company, securities broker, trustee or other intermediary, you are a “Non-registered Shareholder” and you will not have a physical share certificate. In this case, you will have an account statement from your bank or broker as evidence of your Share ownership.

Most Shareholders are Non-registered Shareholders. The Shares of Non-registered Shareholders are registered in the name of an intermediary, such as a bank, trust company, securities broker, trustee, custodian or other nominee who holds the Shares in a nominee account or in the name of such nominee, or in the name of a clearing agency in which the intermediary is a participant (such as CDS). Intermediaries have obligations to forward Meeting materials to such Non-registered Shareholders unless instructed otherwise by the holder (and as required by regulation in some cases, despite such instructions).

Non-registered Shareholders fall into two categories — those who object to their identity being known to the issuers of the securities which they own (“OBOs”) and those who do not object to their identity being made known to the issuers of the securities which they own (“NOBOs”). Subject to the provisions of NI 54-101, issuers may request and obtain a list of their NOBOs from intermediaries directly or via their transfer agent and may obtain and use the NOBO list for the distribution of proxy-related materials to such NOBOs. These securityholder materials are being sent to both registered and non-registered owners of securities of the Company. If you are a non-registered owner (a NOBO or an OBO) and the Company or its agent has sent the Meeting materials directly to you, your name, address and information about your holdings of Common shares have been obtained in accordance with applicable securities regulatory requirements from the intermediary holding the Common shares on your behalf. The Company’s OBOs

9

can expect to be contacted by their intermediary. The Company does not intend to pay for intermediaries to deliver the Meeting materials to OBOs and it is the responsibility of such intermediaries to ensure delivery of the Meeting materials to their OBOs.

Q. Must I use the enclosed form of proxy?

A.      No. If you do not wish to use the enclosed proxy form, you may use any other form of proxy to appoint your proxyholder, although the Articles require that a form of proxy be substantially in the form enclosed.

Q. Can I appoint someone to vote my Shares other than persons named in the enclosed form of proxy?

A.      Yes. Shareholders who wish to appoint a person other than the management nominees identified in the form of proxy or voting instruction form (including a Non-registered Shareholder who wishes to appoint themselves as their own proxy to attend the Meeting) must carefully follow the instructions in this Circular and on their form of proxy or voting instruction form. These instructions include the additional step of registering such proxyholder with Computershare, after submitting the form of proxy or voting instruction form. Failure to register the proxyholder with Computershare, which will result in the proxyholder not receiving a 15-digit control number to ask questions in the Meeting and, consequently such proxyholder will only be able to follow the Meeting as a guest. Guests may only listen to the Meeting but will not be able to ask questions.

Q. What if my Shares are registered in more than one name or in the name of my company?

A.      If your Shares are registered in more than one name, all those registered must sign the form of proxy. If your Shares are registered in the name of your company or any name other than yours, we may require that you provide documentation that proves you are authorized to sign the form of proxy.

Q. What if I plan to attend the Meeting and vote at the Meeting?

A.      If you are a Registered Shareholder and plan to attend the Meeting and you wish to vote your Shares at the Meeting, do not complete or return a form of proxy. Your vote will be taken and counted at the Meeting.

If your Shares are not registered in your name, but you wish to attend the Meeting, please see “Voting by Non-registered Shareholders”.

Q. What happens when I sign and return a form of proxy?

A.      You will have given authority to whomever you have appointed as your proxyholder to vote your Shares at the Meeting in accordance with the voting instructions you provide.

Q. What do I do with my completed form of proxy?

A.      You must deposit your completed form of proxy (by mail, telephone, fax or online) with Computershare no later than 11:30 a.m. (Vancouver time) on April 14, 2023, or at least 48 hours (excluding Saturdays, Sundays and holidays) prior to the time of any adjournment or postponement of the Meeting. The Chair of the Meeting has the discretion to accept or reject any late proxies, and can waive or extend the deadline for receiving proxy voting instructions without notice. If you hold Shares through an intermediary you should refer to “Voting by Non-registered Shareholders”.

10

Q. How will my Shares be voted if my proxy is in the enclosed form with no other person named as proxyholder?

A.       The persons named in it will vote or withhold from voting your Shares in accordance with your instructions. In the absence of such instructions, however, your Shares will be voted FOR fixing the number of Directors at 11, FOR the election of the Directors nominated by management, FOR the appointment of the Auditor, FOR the advisory (non-binding) resolution on the Company’s approach to executive compensation, and FOR the resolution to amend, reconfirm and continue the Company’s Rights Plan.

Q. If I change my mind, can I revoke my proxy once I have given it?

A.      In addition to revocation in any other manner permitted by law, a Registered Shareholder who has completed a form of proxy may revoke it by:

● executing a new form of proxy bearing a later date or by executing a valid notice of revocation, either of the foregoing to be executed by the Registered Shareholder or the Registered Shareholder’s authorized attorney in writing or, if the Registered Shareholder is a corporation, under its corporate seal by an officer or attorney duly authorized, and by delivering the form of proxy bearing a later date or notice of revocation to Computershare, or to the Company’s registered office at Royal Centre, Suite 1500, 1055 West Georgia Street, Vancouver, British Columbia, V6E 4N7, at any time up to and including the last business day that precedes the day of the Meeting or, if the Meeting is adjourned, the last business day that precedes any reconvening thereof, or to the chairman of the Meeting on the day of the Meeting or any reconvening thereof, or in any other manner provided by law; or

● personally attending the Meeting and voting at the Meeting.

A revocation of a form of proxy will not affect a matter on which a vote is taken before the revocation.

Non-registered Shareholders who wish to change their vote must, within sufficient time in advance of the Meeting, arrange for their respective intermediaries to change their vote.

Q. What documents are sent to Shareholders?

A.     Registered Shareholders who have provided us with the required request will receive a package of the usual annual corporate documents (our Annual Report, our consolidated financial statements for the years ended December 31, 2022 and 2021 and Auditor’s report and management’s discussion and analysis thereon), along with the Notice and the form of proxy.

VOTING BY NON-REGISTERED SHAREHOLDERS

Q. If my Shares are not registered in my name, how do I vote my Shares?

A.      Our share register does not list Non-registered Shareholders. The Shares of Non-registered Shareholders are usually held in the name of an intermediary or a “nominee”, such as a trust company, securities broker or other financial institution. If you are a Non-registered Shareholder, there are two ways that you can vote your Shares:

1. By providing voting instructions to your nominee

Applicable securities laws require institutional nominees to seek voting instructions from you in advance of the Meeting. Accordingly, you will receive, or have already received with these materials, from your nominee, either a voting instruction form or a form of proxy for the number of Shares you hold with that nominee. Every institutional nominee has its own mailing procedures and provides its own signing and return instructions, which you should follow carefully to ensure that your Shares are voted at the Meeting.

As the Company is relying on notice and access provisions of applicable Canadian securities law, the Notice and voting instruction form are being sent to both Non-registered Shareholders and Registered Shareholders.

2. By being appointed as Proxy and attending the Meeting

The Company generally does not have access to the names of its Non-registered Shareholders. Therefore, if you attend the Meeting, the Company will have no record of your shareholdings or of your entitlement to vote unless you have directed your nominee to appoint you as proxyholder.

If you wish to attend the Meeting and vote your Shares, insert your own name in the space provided on the voting instruction form or form of proxy provided by your nominee to appoint yourself as proxyholder. If you are a Non-registered Shareholder and instruct your nominee to appoint yourself as proxyholder, you

12

must follow the additional steps set out above under the heading “How to Vote – How Non-registered Shareholders/Appointees can obtain a control number to vote during the Meeting”.

SHAREHOLDER RIGHTS PLAN

Q. What is the Rights Plan?

A.         The Company adopted the shareholder rights plan (the “Rights Plan”) effective April 9, 2020. At the Meeting, you will be asked to consider and, if deemed advisable, pass a resolution, confirming and approving the amendment, restatement and continuation of the Rights Plan. The Rights Plan is an arrangement that gives holders of Common shares of West Fraser, other than a person that acquires above a specified threshold (20% or more) of the Company’s Common shares, the right to acquire additional Common shares of West Fraser at a discounted price in certain circumstances as described below. The Rights Plan encourages fair treatment of West Fraser Shareholders in connection with a take-over bid and protects against “creeping bids” (the accumulation of more than 20% of the Company’s shares through purchases exempt from the formal take-over bid rules). Page 39 of the Circular, under the heading “Resolution to Reconfirm the Shareholder Rights Plan”, provides detailed information regarding the Rights Plan.

Q. Why is the Rights Plan being amended and restated?

A.         At a meeting on February 14, 2023, the Board approved, subject to the approval of Shareholders, the continuation of the Rights Plan on the terms and conditions of the Rights Plan between the Company and Computershare Trust Company of Canada, as successor to TSX Trust Company (“TSX Trust”) (formerly AST Trust Company (Canada)), as Rights Agent. The Rights Plan includes amendments to reflect the appointment of Computershare as successor to TSX Trust Company. The change of Rights Agent to Computershare under the Rights Plan was effective as of November 1, 2021 pursuant to a Successor Rights Plan Agreement entered into between the Company, Computershare and TSX Trust. The Rights Plan does not include any substantive change to the Rights outstanding under the original Rights Plan and represents a continuation of the original Rights Plan, with Computershare as the Rights Agent.

Q. Why is West Fraser Reconfirming and Continuing the Rights Plan?

A.        The Company believes it is appropriate to renew and continue the Rights Plan to protect Shareholders. In accordance with its terms, the Rights Plan must be reconfirmed by Shareholders every three years. The Company adopted the Rights Plan effective April 9, 2020 and it was ratified and approved by the Shareholders at the annual general meeting held on May 26, 2020. The Rights Plan has a term of nine years, subject to approval of its continuance by the Shareholders of the Company at the annual meetings of the Company in 2023 and 2026. Failing reconfirmation as required under the Rights Plan, the Rights Plan and all outstanding Rights thereunder will terminate at the conclusion of the Meeting.

The basic objectives of the Rights Plan are to:

● help ensure that West Fraser Shareholders are treated fairly in connection with any take-over bid made for the Company;

● provide all West Fraser Shareholders with an equal opportunity to participate in such a take-over bid;

● provide the Board with sufficient time to consider and, if appropriate, to develop alternatives for enhancing shareholder value;

● deter abusive tactics by making them unacceptably expensive to unsolicited bidders;

13

● encourage prospective acquirors to negotiate with the Board rather than to attempt an unsolicited hostile take-over; and

● prevent “creeping bids” (the accumulation of more than 20% of the Company’s Common shares through purchases exempt from the take-over bid rules) and “hard” lock-up agreements (agreements with an offeror under which existing Shareholders commit to tender their shares to the offeror’s take-over bid which agreements are either irrevocable or revocable but subject to restrictive termination conditions). See page 39 of the Circular, under the heading “Resolution to Reconfirm the Shareholder Rights Plan”, for further details on “creeping bids” and “hard” lock-up agreements.

Q.: Has West Fraser received a take-over offer?

A.      No. As at the date hereof, West Fraser is not aware of any pending or threatened take-over bid for the Company and the Rights Plan is not being adopted in response to or in anticipation of any pending or threatened take-over bid, nor to deter take-over bids generally, but to encourage fair treatment of West Fraser Shareholders in connection with a take-over bid and to protect against creeping bids.

Q. How does the Rights Plan work?

A.      The Rights Plan is an agreement granting the holders of Common shares certain rights (the “Rights”) to acquire additional Common shares at a discounted price which they may exercise only upon the occurrence of a specified set of events. The Rights are interests which “attach” to Common shares outstanding on April 9, 2020 and to Common shares issued after that date. The Rights Plan encourages a potential acquiror to proceed either by way of a “Permitted Bid” (described below), which requires the take-over bid to satisfy certain minimum standards designed to promote fairness, or with the concurrence of the Board.

Q. What are the Permitted Bid Requirements?

A.      The following is a summary of the primary Permitted Bid requirements:

● the take-over bid must be made to all holders of Common shares other than the offeror;

● the take-over bid must be open to Shareholders for a period of not less than 105 days and the offeror may only take-up and pay for the shares if over 50% of the shares have been tendered to the offer; and

● the take-over offer must also provide that any shares deposited pursuant to the offer may be withdrawn until taken up and paid for.

There are additional requirements that must be met in order for a take-over offer to be a “Permitted Bid” and those requirements are summarized on page 39 of the Circular under the heading “Resolution to Reconfirm the Shareholder Rights Plan”.

Q. What Rights are outstanding?

A:      Effective April 9, 2020, holders of Common shares received one Right per Common share that they owned. The Rights are interests that attach to Common shares. Thus, if the Common shares were sold or purchased, the Rights were sold or purchased with such Common shares.Shareholders did not and will not receive a separate Rights certificate in the mail and will not need to do anything at this time. If the Rights become exercisable, West Fraser’s designated rights agent will forward additional documentation at that time.

14

Q. Can the Rights be sold?

A.         The Rights cannot be sold or conveyed separately from the Common shares to which they relate, unless they become exercisable as described herein. The Rights are interests that attach to Common shares. Thus, if you sell the Common shares, the Rights are sold with the shares.

Q. Has the Board approved the Rights Plan?

A.         Yes. The Board has approved the amendment, restatement and continuation of the Rights Plan. The Board believes that the Rights Plan is in the best interests of West Fraser and our Shareholders. The Board unanimously recommends that Shareholders vote FOR the Rights Plan. In the opinion of the Board, the Rights Plan is consistent with the current practices of Canadian public companies with respect to shareholder rights plans.

Q. What are Shareholders being asked to approve?

A.       Shareholders will be asked to consider an ordinary resolution reconfirming and continuing the Rights Plan. The text of the resolution is included on page 39 of the Circular, under the heading “Resolution to Reconfirm the Shareholder Rights Plan”. Ratification and approval of the Rights Plan by Shareholders is required by the rules of the TSX. If the resolution is not passed, the Rights Plan will terminate as of the close of the meeting.

Q. Will the issuance of Rights be taxable?

A.        The Company considers that the Rights have negligible value when issued, and the issuance of the Rights is not expected to be taxable to holders of Common shares.

Q. Do other companies have shareholder rights plans?

A.         Rights plans have been adopted and reconfirmed by a large number of publicly held companies in Canada. The Management of the Company has reviewed the Rights Plan for conformity with current practices of Company’s peers and other dual-listed Canadian issuers with respect to shareholder rights plan design and has confirmed to the Board that the terms of the Rights Plan are substantially similar to those plans. Based on this review, the Board has determined that it is advisable and in the best interests of the Company and its Shareholders that the Company continue to have in place a shareholder rights plan in the form of the Rights Plan.

The consolidated financial statements are included in our Annual Report which is being mailed to those Shareholders who have provided us with the required request.

2)      Fixing the Number and Election of Directors

Robert Phillips has decided not to stand for re-election as a Director. Management is nominating Doyle Beneby as a new Director along with the other 10 current Directors. As a result, management is seeking approval to fix the number of Directors at 11.

The table of nominees on the following pages sets out the name, background and experience of each person proposed to be nominated for election as a Director, as well as other relevant information. Management of the Company recommends the election of the 11 nominees set out in the table of nominees to fill the 11 positions as Director. The term of office of each current Director will expire at the conclusion of the Meeting. Each Director elected at the Meeting will hold office until the conclusion of the next annual meeting of Shareholders at which a successor Director is elected, unless the Director’s office is earlier vacated in accordance with the Articles or the provisions of the BCA.

The Board of Directors has adopted a majority voting policy, which is described under the heading “Majority Voting Policy”, relating to the election of Directors.

On February 13, 2014, the Board adopted an advance notice policy setting out requirements for Director nominations and elections. On April 29, 2014, our Shareholders approved a special resolution to amend the Articles to include this advance notice requirement, which is described under the heading “Advance Notice Policy”.

The Board of Directors may fill vacancies on the Board resulting from the death, resignation or retirement of Directors. As well, the Board is authorized to appoint up to one-third additional Directors to hold office until not later than the next annual meeting of Shareholders.

3)      Appointment of Auditor

The Auditor is to be appointed to serve until the close of the next annual meeting of Shareholders, and the Directors are to be authorized to fix the Auditor’s remuneration.

The Board of Directors and management of the Company, on the advice of the Audit Committee of the Board, recommend that PricewaterhouseCoopers LLP, Vancouver, Canada, be appointed as Auditor, at a remuneration to be fixed by the Board of Directors.

4)      Advisory Resolution on our Approach to Executive Compensation (Say on Pay)

Our executive compensation philosophy, policies and programs are based on the fundamental principle of pay-for-performance to align the interests of our executives with those of our Shareholders. At the Meeting,

16

Shareholders will be asked to consider and, if deemed advisable, to approve (on an advisory basis), by way of ordinary resolution, the Company’s approach to executive compensation.

5)      Reconfirmation of the Rights Plan

At the Meeting, Shareholders will be asked to consider and, if deemed advisable reconfirm and approve, by way of ordinary resolution, amendment, restatement and continuation of the Rights Plan. The Company adopted the Rights Plan effective April 9, 2020 and it was ratified and approved by the Shareholders at the annual general meeting held on May 26, 2020. The Rights Plan has a term of nine years, subject to approval of its continuance by the Shareholders of the Company at the annual meetings of the Company in 2023 and 2026. Failing reconfirmation as required under the Rights Plan, the Rights Plan and all outstanding Rights thereunder will terminate at the conclusion of the Meeting.

The Rights Plan is an arrangement that gives holders of Common shares, other than a person that acquires above a specified threshold (20% or more) of the Common shares, the right to acquire additional Common shares at a discounted price in certain circumstances as described herein. The Rights Plan encourages the fair treatment of our Shareholders in connection with a take-over bid and protects against “creeping bids” (the accumulation of more than 20% of the Company’s Common shares through purchases exempt from the formal take-over bid rules).

Board Renewal

The Board recognizes the need for, and benefits of, introducing new and diverse characteristics and perspectives at the Board level, and it also understands the importance of having continuity of institutional and industry knowledge and experience. Our Board renewal process is designed to achieve and maintain a balance between those considerations.

The Governance Committee is responsible for identifying new candidates to stand as nominees for election or appointment as Directors to our Board. In identifying potential Director candidates, the Governance Committee takes into account a broad variety of factors it considers appropriate, including skills, independence, financial acumen, Board dynamics and personal characteristics. In addition, the Governance Committee considers diversity in perspective arising from personal, professional or other attributes and experiences when identifying potential Director candidates. Desirable individual characteristics of nominees include integrity, credibility, the ability to generate public confidence and maintain the goodwill and confidence of our Shareholders, sound and independent business judgment, general good health and the capability and willingness to travel to, attend and contribute at Board functions on a regular basis. Background checks, as appropriate, are completed prior to nomination.

In 2015, the Governance Committee implemented the first phase of the Board renewal process by searching for and identifying two suitable candidates for nomination as Directors. As part of this process, the Governance Committee engaged an outside search firm and also sought input and advice from current Directors and our executive management. The major criteria adopted by the Governance Committee for candidates were: (a) chief executive officer experience; (b) experience in a cyclical, capital-intensive industry; (c) strong strategic thinker; and (d) representing diverse background and experience.

As a result of this process, in 2016, Reid Carter and John Floren were identified as nominees to the Board and they were elected as Directors at the 2016 annual meeting of Shareholders.

In 2016, the Governance Committee implemented the second phase of the Board renewal process through continuing efforts to search for and identify additional suitable candidates. As a result, the Governance Committee identified Brian Kenning and Gillian Winckler as important additions to the Board and they were elected as Directors at the 2017 annual meeting of Shareholders. Additionally, as part of the second phase of this process, Clark Binkley, Duncan Gibson and Harald Ludwig retired and did not stand for re-election as Directors.

The Governance Committee continues to focus on diversity and inclusion and to accelerate diverse representation on our Board, management and talent across the organization. In connection with the Norbord Acquisition, two independent directors of Norbord, being Marian Lawson and Colleen McMorrow, were added to the Board in 2021.

Further at the conclusion of the 2021 annual shareholders meeting, John Ketcham retired from our Board after serving for six years. Ellis Ketcham Johnson was nominated by management for election as a Director and was elected to the Board at the Company’s annual general meeting held April 20, 2021.

At the conclusion of the April 20, 2022 annual and special meeting, Gerry Miller retired from the Board and at the upcoming Meeting, Robert Phillips will be retiring from the Board.

30

To further enhance the Board renewal process, the Company has implemented a robust performance review process and employs a skills matrix to identify skills or experience gaps, which is updated and reviewed based on the advice and recommendation of the Governance Committee.

As a result of the Governance Committee review process and Mr. Phillips upcoming retirement from the Board at the Meeting, the Company engaged an outside search firm and also sought input and advice from current Directors and our executive management to identify a suitable candidate for nomination to the Board. The Company has nominated Doyle Beneby to stand for election at the upcoming Meeting.

Performance Reviews

The Governance Committee regularly, and not less frequently than annually, reviews the performance of the Board and its Committees. This review has been conducted by way of formal questionnaire and report and by informal interviews and discussions led by the Chair. The Board performance review also includes a “peer” or individual Director review process. To date, no significant problem with respect to performance of the Board, any Committee or any individual Director has been identified.

Skills Matrix

The Governance Committee uses a skills matrix to assist in the process of identifying suitable additions to the Board. The Governance Committee reviews a matrix that sets out the various skills and experience considered to be desirable for the Board to possess in the context of the Company’s strategic direction. The Governance Committee then assesses the skills and experience of each current Board member against this matrix. When completed, the matrix helps the Governance Committee identify any skills or experience gaps and provides the basis for a search to be conducted for new Directors to fill any gaps.

In February 2022, on the recommendation of the Governance Committee, the Board adopted changes to the skills matrix to align with the Company’s strategic direction and the skills and experience desirable for the Board. The Board believes the revised skills matrix is better aligned to meet the current skills and experience for the Board as a dual-listed TSX and NYSE company and the expectations of its Shareholders.

The following skills matrix sets out the skills or experience that the Governance Committee has targeted for Directors.

	Target Number

The key skills and experience of each Director are also set out in the table under the heading “Information Regarding Nominees for Election as Directors”. The Board is of the view that the minimum target levels have been achieved by the current Board and will be achieved assuming all nominees described above are elected at the Meeting.

Board Tenure

The Company does not have term limits for its Directors, as the Board is of the view that term limits are arbitrary and can result in the removal or exclusion of valuable and experienced Directors solely because of length of service. For similar reasons, in September 2016, the Board considered the continued use of an age limitation for Directors and determined that its continuation was no longer appropriate nor in the best interests of the Company. The Board believes that arbitrary age or term limits can be detrimental to the Company by excluding experienced and valuable candidates with the accompanying loss of continuity and institutional knowledge. Such belief is consistent with the positions of a number of governance and advisory groups.

32

The decision to not have term limits and to eliminate the age limitation was based upon the Board’s belief that Directors should be assessed on their ability to make meaningful contributions. The Company undertakes regular and rigorous reviews of Board, Committee and Director performance and skills as part of evaluating the overall performance of the Board, Committees and the contributions made by each Director. The Company’s annual performance review and skills assessment is a more meaningful way to evaluate and assess Director performance, and a more effective way to maintain an appropriate balance between the benefits of new and diverse characteristics and perspectives and ensuring there is continuity of institutional and industry knowledge and experience. The Board has demonstrated the effectiveness of its approach.

Over the past seven years, the Company identified and added seven new Board members and five of its long-term serving Board members retired, in addition to Ted Seraphim who retired as our CEO and as a Director in 2019 and Ray Ferris who was appointed our CEO and a Director on Ted’s retirement. The Board is composed of members with an appropriate mix of Directors who are new to the Company, and who bring fresh perspectives, including those with institutional knowledge and experience. With the conclusion of the Meeting, Robert Phillips will also be retiring from the Board.

The following table shows the tenure of the Directors standing for election at the Meeting (and assumes all proposed Director nominee candidates are elected):

Board Tenure
Tenure	Number of Directors	% of Directors1
0 to 1 years	1	9.1
2 to 5 years	4	36.4
6 to 10 years	4	36.4
11 years and over	2	18.2

Note:

1. Totals may not add due to rounding.

Upon election, these Directors will have an average tenure of approximately 8.7years.

Director Compensation

The HR&C Committee regularly reviews our Director compensation policy and, following a review in December 2018 and October 2021 of director compensation programs of our peers, approved a number of changes to Director compensation. The Board adopted a fixed fee Director compensation structure, which, effective October 1, 2021, consists of the following:

Director Compensation Structure
Retainer	Fee
Annual base retainer	$90,0001
Annual equity retainer	$110,000 in DS Units
Annual Committee Chair retainer2	$20,000 per Committee
Chair annual retainer3	$200,000

Notes:

1. Each Director may elect once each year that up to 100% of the annual base retainer and other retainers be paid in DS Units.

2. For each Chair of the Audit Committee, Governance Committee, Health, Safety & Environment Committee and the HR&C Committee.

3. Exclusive of annual base and equity retainers.

Directors are not paid separate meeting fees or fees for Committee membership and are not provided a travel allowance. The HR&C Committee believes that this compensation structure is consistent with current governance best practices and emphasizes that the role of a corporate Director is not confined to

33

attendance and participation at meetings. Directors are reimbursed for out-of-pocket expenses incurred in attending meetings of the Board or Committee meetings or otherwise on Company business.

Under our Equity Holding Requirements Policy, the minimum shareholding requirement for each Director is a multiple of three times the aggregate of a Director’s annual base retainer and annual equity retainer, as described in further detail under the heading “Minimum Equity Holding”. If a Director’s equity ownership exceeds this threshold, that Director has the right to elect to receive cash in lieu of their annual equity retainer payable in DS Units.

The Company has DSU Plans which provides a structure for Directors to accumulate an equity-like holding in the Company. The DSU Plans allows Directors to participate in our growth by providing a deferred payment based on the value of a Common share at the time of redemption. Each Director may elect to receive up to 100% of their annual retainers in DS Units and must receive DS Units in payment of the annual equity retainer, unless the Director has achieved the minimum shareholding requirement and elected to receive cash in lieu of DS Units in payment of the annual equity retainer (see “Minimum Equity Holding”). The DS Units are issued based on the weighted average trading price of the Common shares on the TSX during the five trading days prior to their issue for DS Units issued prior to April 2022 and based on the volume weighted average trading price of the Common shares on the TSX on the trading day immediately prior to their issue for DS Units issued after April 2022. Additional DS Units are issued to take into account the value of dividends paid on Common shares from the date of issue to the date of redemption. DS Units are redeemable only after a Director retires, resigns or otherwise leaves the Board and has ceased to fulfill any other role as an officer or employee of the Company. A holder of DS Units may on redemption elect to redeem DS Units in cash or in Common shares, or a combination of cash and Common shares. The redemption value for each DS Unit a Director has elected to be redeemed in cash is the weighted average of the trading price on the TSX of a Common share over the last five trading days ending on the date of redemption for DS Units issued prior to April 2022 and is the weighted average trading price of the Common shares on the TSX on the trading day immediately before the date of redemption for DS Units issued after April 2022. DS Units qualify as equity for the purposes of the minimum equity holding requirement for Directors.

In addition, Ms. Lawson and Ms. McMorrow continue to hold Norbord DSUs, the number of which have been adjusted by the Exchange Ratio and are to be paid out in reference to Common shares, in accordance with the terms of the Norbord Acquisition. The Norbord DSUs operate in a similar fashion to the DS Units. See “Norbord RSU Plan and DSU Plans”.

The Company has a Directors’ Share Compensation Plan (the “Compensation Plan”), the purpose of which is to enable each Director to participate in our growth by receiving Common shares in lieu of cash for services performed as Directors. Under the Compensation Plan, Common shares are issued after each quarter at a price per share equal to the weighted average of the trading price for the Common shares on the TSX for the last five trading days in the quarter. The maximum number of Common shares that may be allotted for issuance under the Compensation Plan and the DSU Plan is 100,000. As at December 31, 2022, 87,993 DS Units were held by the Directors that could be redeemed for Common shares should a Director who retires, resigns or leaves the Board elect to redeem DS Units for Common shares instead of cash. No DS Units were redeemed for Common shares in 2022. DS Units issued after April 2022 may be redeemed for Common shares should a Director who retires, resigns or leaves the Board elect to redeem DS Units for Common shares instead of cash, but such Common shares will not be issued from treasury, but will be purchased on the open market.

ADVISORY RESOLUTION ON THE COMPANY’S APPROACH TO EXECUTIVE COMPENSATION (SAY ON PAY)

Our executive compensation philosophy, policies and programs are based on the fundamental principle of pay-for-performance to align the interests of our executives with those of our Shareholders. This compensation approach allows us to attract and retain high-performing executives who will be strongly incentivized to create value for our Shareholders on a sustainable basis. As a Shareholder you are asked to consider and approve the following advisory (non-binding) resolution:

39

Resolved, on an advisory basis and not to diminish the role and responsibilities of the Board of Directors, that the Shareholders accept the approach to executive compensation disclosed in the Company’s management information circular delivered in advance of the 2023 annual general and special meeting of the Shareholders of the Company.

Because your Say on Pay vote is advisory, it will not be binding upon the Board. However, the HR&C Committee will review and analyze the results of the vote and take into consideration such results when reviewing executive compensation philosophy, policies and programs. The Board confirms that the Company’s current practices achieve substantially the same results as the Canadian Coalition for Good Governance’s “Say on Pay” Policy for Boards of Directors released in September 2010.

We have held advisory votes on our approach to executive compensation at each annual meeting of Shareholders since 2014. In the most recent “Say on Pay” vote in April 2022, 95% of the votes were voted FOR the Company’s approach to executive compensation.

The management proxyholders intend to vote FOR the approval of the advisory (non-binding) resolution on executive compensation, except in relation to Shares held by a Shareholder who instructs otherwise.

RESOLUTION TO RECONFIRM THE SHAREHOLDER RIGHTS PLAN

The Company is party to a shareholder rights plan agreement, initially implemented on April 9, 2020, which plan was ratified and confirmed by the Company’s Shareholders at the 2020 annual meeting of the Company. The Rights Plan will terminate as of the close of the Meeting unless Shareholders vote at the Meeting to continue its operation.

At a meeting on February 14, 2023, the Board approved, subject to the approval of Shareholders, the continuation of the Rights Plan between the Company and Computershare Investor Services Inc., as successor to TSX Trust Company (formerly AST Trust Company (Canada)), as Rights Agent.

Upon approval, the Rights Plan will continue for the balance of the nine-year term of the original Rights Plan, subject to approval of its continuance by the Shareholders of the Company at the annual meeting of the Company in 2026. Failing reconfirmation as required under the Rights Plan, the Rights Plan and all outstanding Rights thereunder will terminate.

At the Meeting, you will be asked to consider and, if deemed advisable, pass a resolution, reconfirming the Rights Plan. The Rights Plan must be approved by a resolution of: (i) a simple majority of 50% plus one vote of the votes cast by Shareholders, whether in person or by proxy, at the Meeting; and (ii) a simple majority of 50% plus one vote of the votes cast by the Independent Shareholders (as defined in the Rights Plan), whether in person or by proxy, at the Meeting. As of the record date for the Meeting, based on publicly available information, to the knowledge of the Company there are no holders of Common shares that are not Independent Shareholders.

If the Rights Plan is not approved at the Meeting, the Rights Plan will terminate at the end of the Meeting. If the Rights Plan is approved at the Meeting, it will remain in effect and will next require reconfirmation by Shareholders at the 2026 annual meeting of the Shareholders. A summary of the Rights Plan is included below and a complete copy of the Rights Plan is attached to this Circular as Schedule “A”.

The full text of the Rights Plan is available under our profile on SEDAR at www.sedar.com and on EDGAR at www.sec.gov. In the event of any conflict between the provisions thereof. Capitalized terms used in this

40

section “Resolution to Reconfirm the Shareholder Rights Plan” but not otherwise defined have the meaning given to those terms in the Rights Plan.

Purpose

The Company believes it is appropriate to continue with the Rights Plan to protect Shareholders. A rights plan is an effective device to deter accumulations of controlling blocks of shares without paying a premium and to maximize leverage regarding the timing and outcome of an unsolicited take-over bid. The basic objectives of the Rights Plan are to deter abusive tactics by making them unacceptably expensive to the unsolicited bidder and to encourage prospective acquirors to negotiate with the Board rather than to attempt an unsolicited hostile take-over or a creeping bid or accumulation of control (including negative control).

The Rights Plan limits acquisitions by a Shareholder or a group acting jointly or in concert that would result in the ownership or control of 20% or more of the issued and outstanding Common shares through means that are exempt from the formal take-over bid rules and to provide Shareholders with an equal opportunity to participate in a take-over bid and receive full and fair value for their shares. To accomplish this, the Rights Plan provides for the issuance to all holders of Common shares of Rights to acquire additional Common shares at a significant discount to the then-prevailing market price, which could, in certain circumstances, become exercisable by all holders of Common shares other than the potential acquiror and its joint actors. The terms of the Rights Plan are substantially similar to the terms of rights plans adopted recently by other substantial Canadian issuers. Holders of Class B Common shares will be issued Rights if those shares are converted to Common shares prior to the Separation Time (as defined below).

The Rights Plan encourages a potential acquiror who makes a take-over bid to proceed either by way of a Permitted Bid (described below), which generally requires a take-over bid to satisfy certain minimum standards designed to promote fairness, or with the concurrence of the Board. If a take-over bid fails to meet these minimum standards and the Rights Plan is not waived by the Board, the Rights Plan provides that holders of Common shares, other than the acquiror and its joint actors, will be able to purchase additional Common shares at a significant discount to market, thus exposing the person acquiring shares to substantial dilution of its holdings.

As at the date hereof, West Fraser is not aware of any pending or threatened take-over bid for the Company and approval of the Rights Plan is not being proposed in response to or in anticipation of any pending or threatened take-over bid, nor to deter take-over bids generally, but to encourage fair treatment of West Fraser Shareholders in connection with a take-over bid and to protect against “creeping bids.”

In continuing with the Rights Plan, the Company and the Board considered the existing legislative framework governing take-over bids in Canada. The Canadian Securities Administrators (the “CSA”) adopted amendments to that framework in 2016 that, among other things, lengthen the minimum bid period to 105 days (from the previous 35 days), require that all non-exempt take-over bids meet a minimum tender requirement of more than 50% of the outstanding securities held by Shareholders other than the offeror, its affiliates and persons acting jointly or in concert with the offeror, and require a 10-day extension after the minimum tender requirement is met. A target issuer has the ability to voluntarily reduce the minimum bid period to not less than 35 days and the minimum bid period may be reduced due to the existence of certain competing take-over bids or alternative change in control transactions.

As the legislative amendments do not apply to exempt take-over bids, there continues to be an important role for rights plans in protecting Canadian public companies and preventing the unequal treatment of Shareholders.

Rights plans continue to be adopted to address the following concerns:

41

1. Protecting against “creeping bids” (the accumulation of 20% or more of shares through purchases exempt from Canadian take-over bid rules, such as (a) purchases from five or fewer Shareholders under private agreements at a premium to the market price (not to exceed 115% of the market price, including brokerage fees and commissions), and not available to all Shareholders, (b) acquiring control or effective control through the accumulation of shares over a stock exchange or other published market without paying a control premium (known as the 5% ordinary course purchase exemption), or (c) through other transactions outside of Canada that may not be jurisdictionally subject to Canadian take-over bid rules), and requiring the bid to be made to all Shareholders; and

2. Preventing a potential acquiror from entering into lock-up agreements with existing Shareholders prior to launching a take-over bid, except for permitted lock-up agreements as specified in the Rights Plan. This prevents the use of “hard” lock-up agreements by offerors whereby existing Shareholders commit to tender their shares to an offeror’s take-over bid in lock-up agreements that are either irrevocable or revocable but subject to restrictive termination conditions. Such agreements could have the effect of deterring other potential bidders from bringing forward competing bids, particularly where the number of locked-up shares would make it difficult or unlikely for a competing bidder’s bid to achieve the 50% minimum tender requirement imposed by the take-over bid rules.

In recent years, unsolicited take-over bids have been made for a number of Canadian public companies, many of which had shareholder rights plans. We believe this demonstrates that the existence of a shareholder rights plan does not prevent the making of an unsolicited bid. Further, in a number of these cases, a change of control ultimately occurred at a price in excess of the original offer price. There can be no assurance, however, that the Rights Plan would serve to bring about a similar result.

The Rights Plan does not preclude any Shareholder from using the proxy mechanism of the BCBCA, the Company’s governing corporate statute, to promote a change in the management or direction of the Company, and will have no effect on the rights of Shareholders to requisition a meeting of Shareholders in accordance with the provisions of applicable legislation.

The Rights Plan is not expected to interfere with the day-to-day operations of the Company. Neither the existence of the outstanding Rights nor the issuance of additional Rights in the future will in any way alter the financial condition of the Company, impede its business plans or alter its financial statements. In addition, the Rights Plan is initially not dilutive. However, if a Flip-in Event (described below) occurs and the Rights separate from the Common shares as described below, reported earnings per share and reported cash flow per share on a fully diluted or non-diluted basis may be affected. In addition, holders of Rights not exercising their Rights after a Flip-in Event may suffer substantial dilution.

The Rights Plan provides that holders of Common shares may tender to take-over bids that meet the Permitted Bid criteria. Furthermore, even in the context of a take-over bid that does not meet the Permitted Bid criteria, the Board is always bound to consider any take-over bid for the Company and consider whether or not it should waive the application of the Rights Plan in respect of such bid. In discharging such responsibility, the Board will be required to act with a view to the best interests of the Company and the adoption of the Rights Plan does not affect the duty of the Board to do so.

Review

As part of the review of the Rights Plan, the Company and the Board considered matters including (i) developments in shareholder rights plans and securities legislation since the amendments to the take-over bid regime were adopted in 2016, (ii) the terms and conditions of rights plans recently adopted by other substantial Canadian public companies, (iii) recent experience involving rights plans in the context of take-

42

over bids, and (iv) the commentary of the investment community on these plans. The Company and the Board are satisfied that the Rights Plan is consistent with the latest generation of Canadian rights plans.

Adoption and Approval

The Rights Plan became effective on April 9, 2020 upon approval and adoption by the Board. The Rights Plan was then ratified and confirmed by the Company’s Shareholders at the 2020 annual meeting of the Company. On February 14, 2023, the Board approved the continuation of the Rights Plan subject to approval by Shareholders. Provided the Shareholders reconfirm the Rights Plan at the Meeting, and also reconfirm at the Company’s annual meeting in 2026, the Rights Plan will continue and will expire upon the conclusion of Company’s annual meeting in 2029.

Issue of Rights

One Right was issued and attached to each Common share outstanding when the Rights Plan was adopted on April 9, 2020, and will attach to each Common share issued prior to the earlier of the Separation Time (as defined below) and the expiration time (the “Expiration Time”) of the Rights Plan.

Rights Exercise Privilege

The Rights will separate from the Common shares and will be exercisable for 10 trading days (the “Separation Time”) after a person has acquired, or commences an offer to acquire, 20% or more of the Common shares, other than by an acquisition pursuant to a take-over bid permitted by the Rights Plan (a Permitted Bid (defined below)). The acquisition by any person (an “Acquiring Person”) of more than 20% of the Common shares, other than by way of a Permitted Bid, is referred to as a “Flip-in Event.” Any Rights held by an Acquiring Person will become void upon the occurrence of a Flip-in Event. Ten trading days after the occurrence of the Flip-in Event, each Right (other than those held by the Acquiring Person) will permit the purchase 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. For instance, if the market price at the Separation Time is $100 it would translate to an exercise price of $500 and entitle the holder to acquire Common shares worth $1,000.

Certificates and Transferability

Prior to the Separation Time, the Rights will be evidenced by the applicable certificates for Common shares or by the applicable book entry form registration for the associated Common shares and will be transferable only together with, and will be transferred by a transfer of, such associated Common shares issued from and after adoption of the Rights Plan on April 9, 2020 and will not be transferable separately from Common shares. From and after the Separation Time, the Rights will be evidenced by Rights certificates, which will be transferable and traded separately from the Common shares.

Permitted Lock-up Agreements

The Rights Plan requires that a person making a take-over bid must structure any lock-up agreement so as to provide reasonable flexibility to the Shareholder in order to avoid being deemed the beneficial owner of the Common shares subject to the lock-up agreement and potentially triggering the provisions of the Rights Plan.

Under the Rights Plan, a person will not be deemed to “beneficially own” any security where the holder of such security has agreed to deposit or tender such security pursuant to a “Permitted Lock-up Agreement”.

43

A Permitted Lock-up Agreement is essentially an agreement between a person and one or more holders of Common shares pursuant to which each locked-up person agrees to deposit or tender Common shares to the locked-up bid and which further (i) permits the locked-up person to withdraw their Common shares in order to deposit or tender the Common shares to another take-over bid or support another transaction at a price or value that exceeds the price under the lock-up bid; or (ii) permits the locked-up person to withdraw their Common shares in order to deposit or tender the Common shares to another take-over bid or support another transaction at an offering price that exceeds the offering price in the locked-up bid by as much as or more than a specified amount and that does not provide for a specified amount greater than 7% of the offering price in the lock-up bid.

Permitted Bid Requirements

The Rights Plan is “triggered” when a person acquires or announces its intention to acquire 20% or more of the Common shares, unless the take-over bid has been conducted in accordance with a stringent set of requirements outlined in the Rights plan (a “Permitted Bid”) or the Rights Plan is waived by the Board.

The requirements for a Permitted Bid include the following:

• The take-over bid must be made to all holders of record of Common shares;

• The take-over bid must contain an irrevocable and unqualified condition that no Common shares will be taken up or paid for:

o prior to the close of business on a date that is not less than 105 days following the date of the bid, or such shorter minimum period as determined in accordance with section 2.28.2 or section 2.28.3 of National Instrument 62-104 - Take-Over Bids and Issuer Bids (“NI 62-104”) for which a take-over bid (that is not exempt from any of the requirements of Division 5 (Bid Mechanics) of NI 62-104) must remain open for deposits of securities thereunder, in the applicable circumstances at such time, pursuant to NI 62-104, and

o unless, at the close of business on the date Common shares are first taken up or paid for under such bid, more than 50% of the then outstanding Common shares held by Independent Shareholders shall have been tendered or deposited pursuant to the bid and not withdrawn;

• Unless the take-over bid is withdrawn, shares may be tendered or deposited at any time during the period in which the take-over bid must remain open in accordance with the requirements of NI 62-104, and any shares tendered or deposited pursuant to the take-over bid may be withdrawn until taken up and paid for (subject to certain exceptions in the case of a partial take-over bid in accordance with the requirements of NI 62-104); and

• If a majority of the outstanding Common shares held by Independent Shareholders have been tendered or deposited and not withdrawn as described above, the offeror must make a public announcement of that fact and the take-over bid must be extended for a period of not less than 10 days from the date of such public announcement.

The Rights Plan allows for a competing Permitted Bid (a “Competing Permitted Bid”) to be made while a Permitted Bid is in existence. A Competing Permitted Bid must satisfy all the requirements of a Permitted Bid, except that the minimum deposit period may be shorter as prescribed by NI 62-104.

44

Under the Rights Plan, “Independent Shareholders” means holders of any Common shares, other than (i) any Acquiring Person; (ii) any offeror (other than any person who is not deemed to beneficially own the Common shares held by such person); (iii) any affiliate or associate of any acquiring person or offeror; (iv) any person acting jointly or in concert with any acquiring person or offeror; and (v) any employee benefit plan, stock purchase plan, deferred profit sharing plan and any similar plan or trust for the benefit of employees of West Fraser or a subsidiary of West Fraser, unless the beneficiaries of the plan or trust direct the manner in which the Common shares are to be voted or withheld from voting or direct whether the Common shares are to be tendered to a take-over bid.

Waiver and Redemption

The Board may, prior to a Flip-in Event, waive the dilutive effects of the Rights Plan in respect of a particular Flip-in Event resulting from a take-over bid made by way of a take-over bid circular to all holders of Common shares, in which event such waiver would be deemed also to be a waiver in respect of any other Flip-in Event occurring under a take-over bid made by way of a take-over bid circular to all holders of Common shares. The Board may also waive the Rights Plan in respect of a particular Flip-in Event that has occurred through inadvertence, provided that the Acquiring Person that inadvertently triggered such Flip-in Event reduces its beneficial holdings to 20% or less of the outstanding Common shares within 14 days or such other period as may be specified by the Board. With the majority consent of holders of Common shares or Rights holders at any time prior to the occurrence of a Flip-in Event, the Board may redeem all, but not less than all, of the outstanding Rights at a price of $0.00001 each.

Exemptions for investment advisors (for client accounts), managers of mutual funds, trust companies (acting in their capacity as trustees and administrators), statutory bodies managing investment funds (for employee benefit plans, pension plans, insurance plans or various public bodies), registered pension funds, plans or related trusts and their administrators or trustees, and Crown agents or agencies acquiring greater than 20% of the Common shares are exempted from triggering a Flip-in Event, provided that they are not making, or are not part of a group making, a take-over bid.

Amendment

The Board may amend the Rights Plan with the approval of a simple majority of the votes cast by the Independent Shareholders (or the holders of Rights if the Separation Time has occurred) voting in person or by proxy at a meeting duly called for that purpose. The Board may, without such approval, correct clerical or typographical errors and, subject to such approval at the next meeting of the Shareholders (or holders of Rights, as the case may be), may make amendments to the Rights Plan to maintain its validity due to changes in applicable legislation.

Term

If Shareholders do not reconfirm the Rights Plan at the Meeting, it will terminate at the close of the Meeting. If Shareholders approve the Rights Plan, it must be subsequently reconfirmed by the Independent Shareholders at every third annual meeting following the Meeting. If the Rights Plan is not so reconfirmed or is not presented for reconfirmation at such annual meeting, the Rights Plan and all outstanding Rights thereunder shall terminate and be void and of no further force and effect on and from the date of termination of such annual meeting.

Certain Canadian Federal Income Tax Considerations

The Company will not be required to include any amount in computing the Company’s income for the purposes of the Income Tax Act (Canada) (the “ITA”) as a result of the issuance of the Rights.

45

Under the ITA, the issuance of Rights to a recipient could be considered as a taxable benefit, the value of which is required to be included in computing the income of a Canadian resident recipient or is subject to withholding tax in the case of a recipient who is not a resident of Canada. In any event, however, no amount in respect of the value of the Rights on issuance is required to be included in computing income, or subject to withholding tax, if the Rights do not have any value at the date of issue. The Company considers that the Rights have negligible value when issued, there being only a remote possibility that the Rights will ever be exercised.

The foregoing does not address the Canadian income tax consequences of other events such as the separation of the Rights from the Common shares, the occurrence of a Flip-in Event or the redemption of Rights. A holder of Rights could be required to include an amount in computing income or be subject to withholding tax under the ITA if the Rights become exercisable or are exercised. A holder of Rights may be subject to tax under the ITA in respect of the proceeds of disposition of such Rights.

This statement is of a general nature only and is not intended to constitute nor should it be construed to constitute legal or tax advice to any particular holder of Common shares. Such Shareholders are advised to consult their own tax advisors regarding the consequences of acquiring, holding, exercising or otherwise disposing of their Rights, taking into account their own particular circumstances and any applicable federal, provincial, territorial or foreign legislation.

Recommendation of the Board of Directors

Management considered and reviewed, with support from external counsel, the Rights Plan and analysis of the continuation of a shareholder rights plan for the Company, considering matters including (i) developments in shareholder rights plans and securities legislation since the Rights Plan was adopted in 2020, (ii) the terms and conditions of rights plans recently adopted by other large Canadian companies, and (iii) the commentary of the investment community on these plans. The Board is satisfied that the Rights Plan remains consistent with the latest generation of Canadian rights plans.

It is not the intention of the Board, in recommending the ratification of the Rights Plan, to either secure the continuance of the directors or management of the Company or to preclude an acquisition of control of the Company in a transaction that is fair and in the best interests of the Shareholders. The rights of Shareholders under existing law to seek a change in management of the Company or to influence or promote action of management in a particular manner will not be affected by the Rights Plan. The Rights Plan provides that Shareholders may tender to take-over bids that meet the Permitted Bid criteria. Furthermore, even in the context of a take-over bid that does not meet the Permitted Bid criteria, the Board is always bound to consider any take-over bid for the Company and consider whether or not it should waive the application of the Rights Plan in respect of such bid. In discharging such responsibility, the Board will be obligated to act honestly and in good faith with a view to the best interests of the Company, and the confirmation of the Rights Plan does not affect the duty of the Board to comply with these obligations.

Management and the Board recommend that Shareholders vote FOR the ordinary resolution set forth below. The management proxyholders intend to vote FOR this resolution except in relation to shares held by a Shareholder who instructs otherwise.

Voting Requirements

At the Meeting you will be asked to approve the ordinary resolution set out below. In order to be effective, the resolution to be voted on will require the approval of a simple majority of the votes cast by the Shareholders and a simple majority of the votes cast by the Independent Shareholders. As of the record

46

date for the Meeting, based on publicly available information, to the knowledge of the Company there are no holders of Common shares that are not Independent Shareholders. The Board reserves the right to alter any terms of the Rights Plan prior to its ratification and approval by Shareholders at the Meeting if the Board determines that it would be in the best interests of the Company and its Shareholders to do so in light of any developments subsequent to the date of this Circular. In such circumstance, a news release would be issued and the further updated Rights Plan would be filed on SEDAR and EDGAR and presented to Shareholders for approval at the Meeting if the Board determines to revise the Rights Plan, or the Board could determine to not proceed with the Rights Plan at any time prior to the Meeting.

The text of the proposed resolution is as follows:

“BE IT RESOLVED THAT:

1. The continuance, amendment and restatement of the Rights Plan, the terms and conditions of which are set out in the Rights Plan to be dated on or about April 18, 2023, between the Company and Computershare Trust Company of Canada, as Rights Agent, as approved by the Board on February 14, 2023, and substantially as described in the Management Proxy Circular of the Company dated March 9, 2023, be and is hereby ratified, confirmed and approved without amendment;

2. The actions of the directors of the Company in adopting the Rights Plan and in exercising and delivering the Rights Plan be and are hereby ratified, confirmed and approved; and

3. Any director or officer of the Company be and is hereby authorized and directed to execute and deliver for and in name of and on behalf of the Company all such certificates, instruments, agreements, documents and notices and to do all such other acts and things as in such person’s opinion may be necessary or desirable for the purpose of giving effect to this resolution.”

Management and the Board recommend that Shareholders vote FOR the ordinary resolution set forth above.

OUR CORPORATE GOVERNANCE POLICIES AND PROCEDURES

Governance Policy

Our Board believes that sound governance practices are essential to the effective and efficient operation of the Company and to the enhancement of Shareholder value. We established a corporate governance policy (the “Governance Policy”) in 2002 which was updated and re-approved by our Board on September 7, 2022. The Governance Policy is reviewed annually by the Governance Committee which, from time to time, recommends updates and changes to such policy to the Board as may be required. The full text of the Governance Policy may be reviewed on our website at www.westfraser.com.

The following disclosure has been prepared under the direction of our Governance Committee and has been approved by the Board.

Chair of the Board

Hank Ketcham retired from his role as our Executive Chair effective April 19, 2016 and assumed the position of Chair of the Board. Hank Ketcham was appointed our President and CEO in 1985 and assumed the role of Chair of the Board in 1996. In 2012, he relinquished the title of President and, on March 1, 2013, Mr. Ketcham retired as our CEO and was designated as our Executive Chair of the Board. Ted Seraphim was appointed our President on April 19, 2012 and also became our CEO on March 1, 2013.

47

As part of our senior leadership transition plan, Ray Ferris replaced Mr. Seraphim as our President on April 19, 2018 and replaced Mr. Seraphim as our CEO on June 30, 2019.

For his duties as Chair of the Board, the Board has approved, on the advice of the HR&C Committee, Hank Ketcham’s annual Chair retainer in the aggregate amount of $200,000 per annum, exclusive of annual Director base and equity retainers. As of May 1, 2016, Mr. Ketcham was permitted to elect to receive all or a portion of his compensation in DS Units. Mr. Ketcham ceased to participate in our Bonus Plan after 2014 and ceased to participate in our long-term incentive plans as of January 1, 2016.

The Board has considered the issue of the Chair’s relationship with management in the context of the need to ensure the Board’s independence from management and has determined that the Chair is sufficiently aligned with Shareholder interests to ensure Board independence from management. The Chair is a director and minority shareholder, and is related to the other directors and shareholders, of Ketcham Investments, Inc., whose shareholdings are described under “Voting Securities and Principal Shareholders”. The Board considers that these relationships assure that the interests of the Chair are closely aligned with Shareholder interests and independent of management.

The Board has developed a formal position description for the position of Chair of the Board, which provides that the Chair of the Board leads the Board in its supervision of the business and affairs of the Company and its oversight of management. The responsibilities of the Chair include, among other things: (a) managing the affairs of the Board and monitoring its effectiveness; (b) ensuring that all matters of strategic importance are being dealt with at the Board level during the course of the year; (c) facilitating the Board’s and management’s efforts to promote engagement with, and feedback from, Shareholders and other stakeholders; (d) acting as an advisor to, and principal sounding board for, the CEO; (e) communicating to the CEO any matters arising from the Board’s meetings or meetings with Shareholders and other stakeholders that require management’s attention; and (f) supporting and assisting the Board, the HR&C Committee and the Governance Committee in the evaluation of, and succession planning for, the CEO.

Governance & Nominating Committee

The Board has established a Governance Committee comprised entirely of independent Directors. The mandate of the Governance Committee is summarized later in this Circular under “Committees of the Board”. The Board, through the Governance Committee, monitors changes to the regulatory, business and investment environments with respect to governance practices and regularly reviews governance issues with a view to ensuring that both our Governance Policy and our actual practices continue to serve the best interests of our Shareholders, employees and other stakeholders.

Majority Voting Policy

In February 2011, the Board reviewed and adopted a majority voting policy on the recommendation of the Governance Committee. The majority voting policy has been updated from time to time since adoption including the most recent amendment in February 2021 and reviewed and re-approved annually by the Board. Under this policy, a Director who is elected in an uncontested election with more votes withheld than cast in favour of their election will be required to tender their resignation to the Chair of the Board. If such a Director refuses to tender their resignation, such Director will not be nominated for election the following year. The resignation will be effective when accepted by the Board, and any Director who tenders their resignation may not participate in the deliberations of either the Committee or the Board which relate to such Director’s resignation. This policy does not apply to an election that involves a proxy contest.

The Governance Committee will convene a meeting and will consider the offer of resignation and make its recommendation to the Board on whether the resignation should be accepted. The Governance Committee

48

will generally be expected to recommend to the Board that it accept the resignation, except in exceptional circumstances. The Board expects that resignations will be accepted unless there are exceptional circumstances that warrant a contrary decision. The Board will announce its decision (including the reasons for not accepting any resignation) by way of a news release within 90 days of the date of the Shareholders’ meeting at which the election occurred, and a copy of the news release will be provided to the TSX and the NYSE. Management will not re-nominate for re-election any Director who fails to comply with this policy.

In addition, subject to the requirements of the Articles and the BCA, in the event a majority of the members of the Governance Committee receive a greater number of votes withheld than votes for their election, the other Directors will appoint a Committee consisting only of those other Directors and solely for the purpose of considering the tendered resignations and such Committee will convene a meeting and recommend to the Board whether or not to accept these resignations.

Advance Notice Policy

Pursuant to the advance notice policy adopted by the Board on February 13, 2014, and subsequently incorporated as an amendment to our Articles following approval by Shareholders on April 29, 2014, any additional Director nominations for the Meeting must have been received by the Company no later than the close of business on March 20, 2023. No such nominations have been received as of the date of this Circular. If no such nominations are received by the Company prior to such date, management’s nominees for election as Directors set forth above will be the only nominees eligible to stand for election at the Meeting. The advance notice provisions provide Shareholders, Directors and management of the Company with a clear framework for nominating Directors. See our Articles on SEDAR at www.sedar.com, EDGAR at www.sec.gov/edgar.shtml and our website at www.westfraser.com for the terms of our advance notice provisions.

Code of Conduct

In 2004, the Board approved a code of conduct for the Company and its Directors, officers and employees (the “Code of Conduct”). The Code of Conduct was most recently amended on April 20, 2021 and has been filed on SEDAR under the Company’s profile. The Code of Conduct sets out expectations for compliance with laws, safety and health, environmental stewardship, discrimination and harassment, conflicts of interest, ethical conduct, fair dealing and other areas.

The Code of Conduct also establishes a “whistleblower” procedure for the reporting by any person of potential breaches of the Code of Conduct or other misconduct, including complaints regarding accounting, internal accounting controls or auditing matters. On February 13, 2014, the Board approved amendments to the Code of Conduct which included provisions prohibiting certain insiders who are subject to minimum shareholding requirements from purchasing financial instruments designed to hedge or offset any decrease in the market value of our Shares, Options or units, and, on February 18, 2015, the Board approved amendments to the Code of Conduct, which included additional provisions related to the Company’s commitment to human rights and compliance with anti-bribery laws.

On December 11, 2018, the Board approved further amendments to the Code of Conduct to: (a) provide that the Code of Conduct applies to West Fraser’s contractors, consultants, agents and representatives when acting on behalf of West Fraser; (b) emphasize and expand West Fraser’s commitment to environmental stewardship and supporting the communities in which West Fraser operates; (c) bolster our anti-discrimination and anti-harassment policies in order to ensure a work environment free from discrimination and harassment, in particular sexual harassment; (d) expand the anti-bribery and anti-corruption policy both in terms of persons covered and the activities prohibited; and (e) more clearly articulate provisions relating to substance abuse.

49

In February 2020, the Board approved additional amendments to the Code of Conduct, to align it with current best practices, to provide protection over confidential personal information and to clarify the Company’s expectations regarding the maintenance of Company records and the participation by employees with internal and external investigations.

Further amendments were made to the Code of Conduct in April 2021 for compliance with SEC guidelines that issuers acknowledge the requirement to provide full, fair, accurate, timely and understandable disclosure in reports and documents filed with the SEC. At the same time, the whistleblower provision was updated to further clarify the option for any person to report misconduct through the reporting hotline.

The Code of Conduct includes an acknowledgement with respect to compliance to be confirmed by each Director and each member of management. All Directors, members of management and substantially all salaried employees periodically confirm compliance with the Code of Conduct and any instances of non-compliance are reported to the Board. In 2022, no waivers of the application of the Code of Conduct were requested of, or granted by, the Board. The full text of the Code of Conduct may be viewed on our website at www.westfraser.com.

Anti-Trust Policy

On September 8, 2021, the Company adopted the Anti-Trust Policy outlining our commitment to comply with all applicable competition and antitrust laws, which are in place to prevent activities among competitors that could unfairly control the market and harm the consumer and not engage in activities that would reasonably appear to be an unfair trade practice, unreasonable restraint of trade or an attempt to use a dominant position to discourage competition. We expect all our employees, officers and Directors to comply with the Anti-Trust Policy, a full copy which is available at: www.westfraser.com.

Charters

The Board has developed and approved formal charters for each of the Audit, HR&C, Governance, and Health, Safety & Environment Committees as well as formal position descriptions for each of the positions of Chair of the Board and CEO. The charters of these Committees and position descriptions are reviewed annually and revised, as required, by the Board.

On December 11, 2018, the Board approved amendments to the position descriptions of the Chair of the Board and CEO. The Chair of the Board’s general mandate is to ensure the effective and independent conduct of the Board. The CEO’s general mandate is to implement the Company’s strategic and operating plans and enhance Shareholder value.

The Governance Committee Charter was updated and re-approved by the Board on December 7, 2021 to include some housekeeping matters.

The Health, Safety & Environment Committee Charter was revised and re-approved by the Board on February 15, 2022.

The Audit Committee Charter is reviewed annually and was revised by the Board in 2017 and was again reviewed and updated in February 2020 to provide, among other things, that the Audit Committee would have oversight responsibility over the information technology, cyber security and information systems risks and on April 20, 2021, following the listing of Common shares on the NYSE, the Audit Committee Charter was further revised for compliance with NYSE rules and regulations and conformity with best corporate governance practices. These changes included certain administrative matters such as setting out the matters under the Audit Committee’s oversight responsibility, other disclosure-oriented process items such as

50

specifying that the Audit Committee will review with management and the Auditor all news releases that contain first time disclosure of significant financial information and certain technical items such as setting out in detail the independence and financial literacy qualifications for Audit Committee members.

On December 10, 2019, the Board reviewed and re-approved the HR&C Committee Charter. The HR&C Committee Charter was further updated on February 11, 2021, to provide for conformity with best practices related to engagement of outside advisors or consultants and the NYSE rules for determination of independence of HR&C Committee members. The HR&C Committee Charter was further updated on December 7, 2021 to approve amendments that were part of the adoption of the Pension Oversight Committee of management into the governance structure.

The Company continues to review its Committees’ charters for updates and changes as may be required in connection with best practices and regulatory and stock exchanges requirements and will continue to monitor and update its Committees’ charters as necessary to comply with applicable law and current best governance practices.

Minimum Equity Holding

Under our Equity Holding Requirements Policy, the minimum equity holding requirement for Directors is a number of Shares or DS Units having a value of not less than three times a Director’s total annual base and equity retainers. Based on the current retainer amounts, this would total $600,000.

Shares, DS Units, Norbord DSUs (in the case of Ms. Lawson and Ms. McMorrow) and RS Units held by a Director are eligible to be included in determining whether the minimum equity holding requirement has been met (but Options and PS Units are not eligible). For the purposes of such calculation, Shares, DS Units and Norbord DSUs (in the case of Ms. Lawson and Ms. McMorrow) held by a Director will be valued annually based on the greater of (1) their original cost or grant date value, and (2) the Closing Price on December 31 of the most recently completed financial year (or, if such date is not a trading date, on the last trading date of such year). This policy requires that all Directors meet the minimum equity holding requirement within five years of election or appointment and, if after any annual valuation of a Director’s equity holdings the value of the Director’s holdings fall below the requirement, the Director will have one year to regain compliance.

If a Director exceeds the minimum equity holding requirement, the Director may elect to receive, in lieu of DS Units, all or a designated portion of their annual equity retainer in cash.

For a description of the equity holdings of the Directors as of the Record Date, see the chart under the heading “Payment of 2022 Compensation”. The equity holding requirements for senior executives are described under “Executive Equity Holding Requirements”.

Mandate of the Board

Our Board has expressly assumed overall responsibility for the stewardship of the Company, including responsibility for: (i) adoption of a strategic planning process and approval of a strategic plan; (ii) identification of the principal risks to our business and implementation of appropriate systems to manage these risks; (iii) succession planning, including appointment, training and monitoring of our senior management; (iv) implementation of a communication policy regarding our disclosure of corporate information; and (v) ensuring the integrity of our internal controls and management information systems including accounting systems.

The Board met 11 times in 2022. Independent Directors also met without management at every Board meeting in 2022. During the regularly scheduled meetings, the Board received, reviewed and contributed to management’s strategic planning and operating and capital plans, taking into account identified business opportunities and business risks. In conjunction with the ongoing planning process, the Board regularly reviews, with management, the strategic environment, the emergence of new opportunities and risks, and the implications for our strategic direction.

The Board has, with the advice of management, identified the principal risks to our business and has overseen management’s establishment of systems and procedures to ensure that these risks are monitored. These systems and procedures provide for the effective management of our manufacturing assets, forest resources and financial resources, and compliance with all regulatory obligations. Management prepares and submits annually to the Board a matrix identifying key short-term and long-term enterprise risks together with an analysis of each risk and management’s mitigation strategy. In addition, management regularly reports to the Board on key evolving or new focus risks. The annual risk matrix and the focus risks are reviewed by the Board and consideration is given to any changes in circumstances that could either heighten or diminish the nature of a particular risk. The Board understands that our major risks are associated with safety, the environment, climate change and sustainability, access to raw materials our product end markets, recruitment and retention, and cyber security.

The Board receives and reviews regular reports on our operations, including reports dealing with safety and environmental issues.

52

The Board is responsible for the supervision of our senior management to ensure that our operations are conducted in accordance with objectives set by the Board. All appointments of senior management are approved by the Board. As part of our planning process, succession planning for senior management positions is regularly reviewed and discussed.

ESG Oversight

Our commitment to sustainability starts at the top and at the Board level. Our Board of Directors is responsible for overseeing overall management and integration of sustainability, climate change and environmental, social, and governance (“ESG”) matters throughout the Company. This includes overseeing sustainability strategies and monitoring the practices of the Company relating to health and safety, workplace diversity, equity and inclusion. The Board’s goal is to ensure we operate as a sustainable business, optimizing financial returns while effectively managing risk. ESG governance, risk oversight and disclosure is a regular topic of discussion at Board and committee meetings.

The Company’s approach to ESG continues to grow and evolve in line with the needs, demands and expectations of its shareholders, regulators and stakeholders. In 2021, the Board and management conducted a comprehensive review of our sustainability and ESG-related approach and evaluated both the best practices and approaches of our peers.

As a result of the review, our Board has delegated oversight of certain ESG responsibilities to its Committees and management, which report their findings and provide recommendations to the Board. As ESG is a cross-functional discipline encompassing a wide range of issues, and thus is relevant to all Committees, different aspects of our ESG performance fall under each of our Committees and management. The Committees work together with management to identify ESG issues most pertinent to the Company’s business and its key stakeholders, and to help develop the policies and processes to integrate ESG into the Company’s long-term strategy and risk management responsibilities.

Oversight of governance-related ESG policies and programs is a responsibility that was specifically added in 2021 to the Charter of the Governance Committee, which also is responsible for monitoring diversity at the Board level, corporate governance practices and compliance with the Code of Conduct. In addition to oversight responsibility for the Company’s annual financial statements and audits, the Audit Committee ensures that financial risks, compliance matters and ethics complaints are properly managed and addressed. The HR&C Committee oversees the goals and risks associated with the Company’s compensation programs and oversight of the equity holding policy and the clawback policy. The Health, Safety and Environment Committee is responsible for, among other things, overseeing the Company’s key environmental and sustainability objectives established by management and the Board and reviewing the Company’s current sustainability report. Furthermore, management reports to the Board on issues related to stakeholder engagement, particularly with respect to relationships with local communities and Indigenous peoples and our actions to meaningfully advance reconciliation.

At the management level, West Fraser’s CEO and executive team are responsible for implementing the Company’s strategy and sustainability targets. The Vice-President, Canadian Woodlands oversees compliance with Canadian forestry regulations and certification. He is responsible for the practice and maintenance of sustainable forest management, strategic issues with regard to forest management-related environmental performance, climate risks and opportunities, and forest carbon. The Senior Vice-President, Western Canada oversees pulp and bioproducts manufacturing, bioenergy development, projects, energy reduction initiatives and greenhouse gas emissions reporting. The Manager, Energy & Bioproduct Development leads corporate initiatives in energy reduction, bioproduct research and development and greenhouse gas emissions reporting. The Senior Vice-President, Corporate and Government Relations is responsible for the Company’s sustainability report and regularly engages with federal and provincial

53

governments on climate policy, and the Company’s environmental performance. The Chief Environment and Sustainability Officer assists West Fraser’s operations to meet climate and carbon policy and regulations that may affect the Company or manufacturing facilities.

A snapshot of the Board’s delegated responsibilities to its Committees as related to ESG matters is as follows:

Corporate Disclosure Policy

The Board has, as part of our Governance Policy, approved a corporate disclosure policy (the “Corporate Disclosure Policy”), to be overseen by a disclosure committee (the “Disclosure Committee”) that is intended to ensure that all material information relating to the Company is communicated appropriately to our Shareholders and the public. On February 15, 2022, the Disclosure Policy was revised and the Corporate Disclosure Committee was modified from seven members to a minimum of five members and maximum of seven members, comprised of the CEO, the Senior Vice-President, Finance and CFO and senior leadership from operations, sales and legal as designated by the CEO and the Senior Vice-President

54

and CFO from time to time. Under the Corporate Disclosure Policy, the Disclosure Committee will be responsible for reviewing and approving all material continuous disclosure, including annual and interim financial statements, management discussion and analysis and financial results press releases, other press releases that contain material information or disclosure of first-time significant financial information, information circulars, annual information form, annual reports, prospectuses and other offering or tender documents. The Disclosure Committee will review these materials before they are provided to the Board or the applicable Board committee for review and approval. The Corporate Disclosure Policy may be viewed on our website at www.westfraser.com. In addition to annual meetings of Shareholders, meetings are held from time to time each year between management representatives and various investors, investment analysts, credit rating agencies and financial institutions, all of which are governed by the Corporate Disclosure Policy.

Audit Committee

The Board, through the Audit Committee, is responsible for overseeing our financial reporting and audit process and requiring that management has designed and implemented and maintains an effective system of internal controls and management information systems. The Audit Committee generally meets twice annually with the Auditor to discuss the annual audit. These meetings are in addition to regular meetings, in which the Auditor participates, during which the Audit Committee reviews and approves certain of our quarterly reports. The Audit Committee has been delegated the authority to approve our quarterly financial statements and quarterly earnings announcements before publication, other than those related to the fourth quarter and annual results. At regular meetings, the Audit Committee also meets separately and in-camera with the Auditor without management and separately and in-camera with management without the Auditor. The Audit Committee has complete and unrestricted access to the Auditor.

In 2022, the Audit Committee focused on these key areas:

• reviewing significant accounting and financial reporting issues and assessing the appropriateness of our financial reports;

• overseeing and assessing the adequacy and effectiveness of our internal control procedures over annual and interim financial reporting;

• managing our relationship with the Auditor, through, among other things, a formal review of the performance of the Auditor;

• reviewing with management the adequacy and effectiveness of our systems for monitoring compliance with financial reporting and disclosure laws, including disclosure controls and procedures;

• overseeing compliance with our Code of Conduct and the process through which complaints (including regarding accounting, internal accounting controls or auditing matters or other misconduct) are received and dealt with, including confidential and anonymous submissions and those that are of a sensitive or “whistleblower” nature; and

• identifying and overseeing our principal information technology, cyber security, information security and information technology networks and information systems risks.

In order to provide reasonable assurance that our financial reporting is complete, fairly presented and employs appropriate accounting principles, the Audit Committee reviews the following documents with management and the Auditor and recommends them to the Board for approval:

55

• annual and interim financial statements and reports; and

• the related management’s discussion and analysis of financial performance.

The Audit Committee reviews with management and the Auditor relevant and applicable legal and regulatory developments and the adoption and disclosure of new accounting standards. It also assesses the potential impacts of choosing between accounting alternatives.

As part of its mandate, the Audit Committee is responsible for reviewing any related party transaction in which a Director or a member of senior management has an interest, and making recommendations to the Board. The Audit Committee reviews such transactions in accordance with applicable legislation to ensure they reflect market terms and conditions, are at commercial arm’s length terms, and are in the best interests of the Company. The Audit Committee has the ability to retain independent advisors to provide advice on any proposed related party transactions. Any recommendations or advice pertaining to a specific matter is then communicated to the Board.

The Audit Committee receives regular briefing materials from management, at least semi-annually, on information technology, cyber security, information security and information technology networks and information systems risks, including details of top threats, risk management activities, vendor and supply chain monitoring, and internal training and awareness programs.

We rely on industry accepted security measures and technology to protect our information systems and confidential and proprietary information. Our information security management systems are based on ISO27001: 2022. See the “Risks and Uncertainties - Information Technology and Cyber Security” section of our Management’s Discussion and Analysis for the year ended December 31, 2022, for a discussion of the related risks and uncertainties associated with our business. The Company does not carry cyber security insurance.

Decisions Requiring Prior Approval by the Board

The Board has overall responsibility for the stewardship of the Company. Any responsibility that is not delegated to management or to a Committee remains with the full Board. We maintain policies with respect to matters requiring prior approval of the Board. These policies, and understandings between management and the Board through previous Board practice and accepted legal practice require that our annual operating and capital plans, significant capital expenditures and all transactions or other matters of a material nature involving the Company or any of its subsidiaries must be presented by management for approval by the Board.

Shareholder Feedback and Concerns

The Board and management welcome interaction with our Shareholders and believe that it is important to have direct regular and constructive engagement with our Shareholders to permit open dialogue and the exchange of ideas.

West Fraser communicates with its Shareholders and other stakeholders through various channels, including our annual report, management information circular, annual information form, quarterly reports, news releases, website, presentations at investor and industry conferences and other materials prepared in connection with the continuous disclosure requirements of the TSX, the NYSE and securities regulatory authorities. In addition, our quarterly earnings call is open to all Shareholders. Our website, at www.westfraser.com, also provides extensive information about the Company and all news releases issued by us are available on the website for viewing.

56

We maintain a policy of ongoing communication with investors and with representatives of the investment community. This process consists of periodic meetings with investment fund managers and investment analysts as well as individual investors and Shareholders, although always in circumstances that assure full compliance with disclosure requirements.

Inquiries by Shareholders are directed to, and dealt with by, members of senior management. Shareholders and potential investors are encouraged to communicate on any issues, including those relating to executive and Director compensation, directly with members of our senior management. All communications are subject to our Corporate Disclosure Policy. Shareholders may communicate their views to senior management by contacting our main investor contact as set out below:

Expectations of Management

The Board has determined its expectations of management, which include provision of information and implementation of processes that enable the Board to identify risks and opportunities for the Company, the identification of appropriate comparisons and benchmarks against which our performance may be measured, and the provision of information and data that permits the Board to monitor ongoing operations, and management understands these expectations. As part of the ongoing process of monitoring the performance of management, the Board receives operational updates on each of our business units at each Board meeting. These updates compare actual performance to our annual plan and historical results and include a discussion of all significant variances.

As part of the monitoring process, the CEO submits to the Board at the beginning of each year a written report setting out goals, expectations and priorities for the year. These are reviewed by the Board and may be varied based on the Board’s comments. At the end of the year, a report is submitted to the Board by the CEO that sets out achievements relative to the original goals and expectations. Both the Board and the CEO expect that the level of those achievements will be taken into account when establishing the CEO’s compensation for the following year.

Composition of the Board

Independence

We are required to assess and disclose which of our Directors are, or are not, “independent” of management as that term is used in National Instrument 52-110 – Audit Committees (“NI 52-110”). We also assess the independence of our Directors under the applicable rules of the NYSE. 10 of our 11 current Directors are independent, while Ray Ferris is considered not independent. Below is a summary of the basis of our determinations in respect of all current and proposed Directors:

58

Name	Determination and Basis
Hank Ketcham	Independent (see commentary below)
Doyle Beneby2	Independent
Reid E. Carter	Independent
Ray Ferris	Non-independent (Basis for Determination: Currently our President and CEO)
John N. Floren	Independent
Ellis Ketcham Johnson	Independent (see commentary below)
Brian G. Kenning	Independent
Marian Lawson	Independent
Colleen M. McMorrow	Independent
Robert L. Phillips1	Independent
Janice G. Rennie	Independent
Gillian D. Winckler	Independent

Notes:

1. Mr. Phillips is not standing for re-election at the Meeting.

2. Mr. Beneby has been nominated as a Director at the Meeting.

Where an individual is, or has been within the last three years, an employee or executive officer of an issuer, NI 52-110 provides that such individual is deemed to have a material relationship with the issuer and thus would be considered non-independent of the issuer.

Hank Ketcham was appointed our President and CEO in 1985 and assumed the role of Chair of the Board in 1996. In 2012, he relinquished the title of President and, on March 1, 2013, Mr. Ketcham retired as our CEO and was designated as our Executive Chair of the Board. Hank Ketcham retired from his role as our Executive Chair effective April 19, 2016 and assumed the position of Chair of the Board. As of the Record Date, more than five years has elapsed since Hank Ketcham served in any executive capacity with the Company, and seven years will have elapsed as of the date of the Meeting. Since Hank Ketcham’s retirement as our CEO, the Board has engaged in a board renewal process, which has resulted in the expansion of the size of our Board from nine Directors to 11 Directors and the appointment of six new Directors with no prior relationship with Mr. Ketcham. Mr. Ketcham does not engage in any related party transactions with the Company and does not have any consulting, advisory or other contractual arrangements with the Company outside of his role as the non-executive Chair and a member of the Board.

Having regard to Hank Ketcham’s past relationships with the Company and considering his current relationships with management and the Company and the passage of time and other factors, the Board determined that there are no “material relationships” (within the meaning of NI 52-110) which could, in the view of the Board, be reasonably expected to interfere with Hank Ketcham’s exercise of independent judgment. The Board also considered the issue of the Chair’s relationship with management in the context of the need to ensure the Board’s independence from management and determined that the Chair is sufficiently aligned with Shareholder interests to ensure Board independence from management. The Chair is a director and shareholder, and is related to the other directors and shareholders, of Ketcham Investments, Inc., whose shareholdings are described under “Voting Securities and Principal Shareholders”. The Board also considers that these relationships assure that the interests of the Chair are closely aligned with Shareholder interests.

Ellis Ketcham Johnson was appointed to the Board at the Company’s annual general meeting held April 20, 2021. Ellis Ketcham Johnson is a cousin of Hank Ketcham, the Company’s current Chair and former member of our management. The Board has considered this relationship and interest, including the shareholding interests of Ellis Ketcham Johnson and those of Hank Ketcham, and the fact that neither Ellis Ketcham Johnson nor Hank Ketcham are executives or employees of the Company and do not have

59

any other material financial, familial or other relationship with the Company or its executives, and has determined that Ellis Ketcham Johnson is sufficiently independent of our management and has interests aligned with Shareholders to the extent that such independence qualifies her to be a member of the Board and make a valuable contribution in that role.

The Governance Committee is currently comprised of Robert Phillips (Chair), Reid Carter, John Floren, Brian Kenning and Janice Rennie, all of whom are independent Directors. The Governance Committee was reconstituted to its current membership effective April 20, 2022. The Governance Committee meets without any members of management present as part of each regularly scheduled meeting of the Board. There were four such meetings during 2022.

Diversity – Board and Executive Officers

The Company is committed to providing equal opportunities for individuals who have the necessary qualifications for employment and advancement within the Company. The Company’s objectives, as outlined in its Policy on Diversity Equity and Inclusion as well as its Human Rights, Discrimination & Harassment Policy that is part of our Code of Conduct and its employment practices, include providing an equal opportunity for employment and advancement and a work environment that is free of discrimination and harassment, including based on gender, race, ethnicity, disability or sexual orientation. The Company believes inclusive diverse teams build vibrant workforces, safer operations, and a stronger and more competitive company overall.

If all of the management nominees are elected to the Board, 5 of the 10 of the independent Directors (50%) on the Board and 5 of the 11 directors (45%) will be women and 1 of the 10 of the independent Directors (10%) on the Board and 1 of the 11 directors (9%) will be non-gender diverse.

The Company and its major subsidiaries have in the aggregate eighteen executive officers, including three executives who are gender or non-gender diverse. Although, the Company has not adopted any formal targets regarding gender or non-gender diverse candidates in Director and executive positions, we do consider diversity when considering Director candidates and making employee hiring or advancement decisions. In 2019, we adopted the Board Diversity Policy (described below). The Company firmly believes that all of its stakeholders benefit from the broader exchange of perspectives and balance brought by diversity of background, thought and experience. The Company’s commitment to inclusion and diversity is demonstrated through several facets, including initiatives in recruitment and retention, diversity and inclusion training, the consideration of diversity in employee development and advancement decisions, and workshops for identified diverse successors.

The Company does consider diversity to be important and believes that its current framework for evaluating Board and executive officer candidates takes into account diversity along with a broad variety of factors the Company considers appropriate. The Company also encourages female and minority candidates to apply for vacant positions, and the Company is an equal opportunity employer.

The Company strives to create workplaces and leadership teams that are reflective of the diverse communities where we live and work. Creating a culture of belonging for all employees aligns with our other core values of teamwork, respect, humility, and integrity. Our diversity, equity and inclusion approach applies to all levels of our organization and is foundational to achieving our strategic objectives to attract and retain engaged, talented, and high-performing people.

The Company’s objectives in advancing or recruiting new candidates is to attract, employ and retain engaged, talented and high-performing individuals who bring value to the Company and its Shareholders by possessing a suitable mix of qualifications, experience, skills and expertise. It is ultimately the skills,

60

experience, characteristics and qualifications of the individual that are most important in assessing the value the individual could bring to the Company.

Board Diversity Policy

The Company recognizes the benefits of inclusion and diversity in its broadest sense and considers inclusion and diversity at the Board level to be an essential element of Board effectiveness. The Company views inclusion and diversity on the Board as leading to a better understanding of opportunities, issues and risks; enabling stronger decision-making; and ultimately improving our performance and ability to provide strategic oversight and maximize Shareholder value. To continue progress on this goal, in February 2019, the Board adopted a formal, written policy relating to Board diversity, including gender diversity (the “Board Diversity Policy”). The purpose of the Board Diversity Policy is to promote an environment within the Company that will attract and advance those Director candidates with the widest range of knowledge, skills and experience. While all Director appointments are made based on merit, the Board expects that when selecting and presenting candidates to the Board for appointment, the Governance Committee will consider not only the skills, experience and expertise of a candidate, but also other factors, including gender, race, ethnicity, age and geography to ensure that the Board has a diverse membership. Moreover, the Board recognizes that gender diversity is a significant aspect of diversity and acknowledges the important role that women with the relevant skills and experience can play in contributing to a diversity of perspectives on the Board.

While the Board does not support fixed percentages or quotas for achieving diversity, in recruiting candidates for nomination, the Board and the Governance Committee consider a variety of factors including decision-making ability, skill, geography, experience with businesses of a comparable size, diversity of backgrounds and perspectives, gender, race, ethnicity, age, the interplay of a candidate’s skills and experience with the skills and experience of other Board members and the extent to which a candidate would be a desirable addition to the Board.

The Governance Committee may from time to time consider adopting measurable objectives for achieving diversity on the Board, including gender and minority diversity, and recommend such objectives to the Board for adoption.

The Board Diversity Policy requires the Governance Committee to review and monitor the implementation of the policy on an annual basis to ensure its effectiveness and report the results of its review to the Board. The Board currently has five female Directors. A copy of the Board Diversity Policy is available on the Company’s website at www.westfraser.com.

In addition to the Board Diversity Policy, the charter of the Governance Committee provides that the Governance Committee will review and make recommendations to the Board on the composition of the Board in order to ensure that the Board has the requisite expertise and that its membership consists of persons with sufficiently diverse and independent backgrounds, with a view to facilitating effective decision-making. Similarly, in the process of identifying candidates for executive officer appointments, the Company considers whether our senior executive group consists of persons with sufficiently diverse and independent backgrounds.

Serving on Other Boards

Each of Doyle Beneby, Janice Rennie, Marian Lawson, Colleen McMorrow and Gillian Winckler is an active corporate director serving on several corporate boards. The Board and the Governance Committee have reviewed each of their board memberships and determined that they have devoted, and are expected

61

to continue to devote or in the case of Mr. Beneby expected to devote, the required time and attention to discharge their duties as members of our Board.

Ms. Rennie and Ms. Winckler have each demonstrated a strong understanding of West Fraser’s business, have been and are well prepared for all Board and Committee proceedings, and make consistent and valuable contributions to those proceedings. Similarly, since closing of the Norbord Acquisition in February 2021, when Ms. Lawson and Ms. McMorrow joined the Board of West Fraser, they have each been well prepared and ready for all Board and Committee proceedings. In 2022, Ms. Rennie, Ms. Lawson and Ms. McMorrow each maintained a 100% attendance record at Board and Committee meetings. Ms. Winckler attended 100% of the Board and Health, Safety & Environment Committee meetings and 75% of the Audit Committee meetings. They also made themselves available to meet with management and fellow Directors, and attend tours of the Company’s facilities on an ad hoc basis whenever required to do so.

The disclosure under “Information regarding Nominees for Election as Directors” lists the other public company directorships held by our Directors. West Fraser does not limit the number of outside directorships. The Governance Committee discusses our Director expectations with potential candidates to ensure the candidates understand the time commitments and expectations before agreeing to be nominated as a Director of the Company.

Committees of the Board

The Board has concluded that Committees should be kept to a minimum so that all members of the Board are able to participate in discussions on significant issues. Matters that are outside of management’s authority are reported to and approved by the Board.

Committees may engage outside advisors at the expense of the Company. Under the Governance Policy an individual Director may, with the approval of the Board, retain an outside advisor at the Company’s expense.

The Board has appointed the following four Committees, each of which is comprised entirely of Directors who are not members of our management: Audit Committee; HR&C Committee; Health, Safety & Environment Committee; and Governance Committee.

In order to facilitate open and candid discussion, in-camera sessions are held at every Committee meeting without management present. It is also the practice of each Committee to meet in-camera during each of its meetings. Topics discussed at these meetings include, but are not limited to, Board processes, succession planning, executive assessments, organizational changes, and strategy.

Each Committee chair helps ensure that their Committee governs itself independently of management and discharges its mandate in accordance with the Committee’s charter. Each chair also sets the agenda for their Committee meetings in consultation with other members of the Committee, the Board and senior management, as needed.

Audit Committee

Chair:	Reid E. Carter
Other Members:	Ellis K. Johnson

The Audit Committee is responsible for reviewing our annual financial statements and making recommendations as to the approval of the annual financial statements by the Board. Material issues related to the audit of our internal control and management information systems are discussed by management representatives and the Audit Committee as they arise. The Audit Committee has been delegated the authority to approve our quarterly financial statements and quarterly earnings announcements before publication other than those related to our fourth quarter and annual results. The Audit Committee has direct access to the Auditor and is responsible for approving the nomination, and establishing the independence, of the Auditor. The role of the Audit Committee has been discussed at various times with our Auditor.

Under NI 52-110, the Audit Committee must be comprised of independent directors. An “independent director” is a director that has no direct or indirect material relationship with the Company, including not being affiliated with management or the Company in terms of specific familial or commercial relationships. Each member of our Audit Committee is considered “independent” and, in addition, “financially literate” as such terms are used in NI 52-110.

Additional disclosure concerning the Audit Committee is contained in our Annual Information Form. The full text of the Audit Committee Charter, which forms part of our Annual Information Form, is available for viewing on our website at www.westfraser.com. The Audit Committee Charter is reviewed at least annually and was last revised by the Board on April 20, 2021.

The HR&C Committee is responsible for reviewing and making recommendations to the Board with respect to the remuneration of our executive management and the remuneration of each Director, and has the authority to grant Options to officers and employees under our Stock Option Plan (described below), although in practice the Board gives final approval of all Option grants. The HR&C Committee reviews the remuneration of Directors and executive management each year. The HR&C Committee oversees succession planning of our executive management and reviews and makes recommendation to the Board on proposed executive management appointments. Under its mandate, the HR&C Committee is authorized to retain or obtain the advice of independent compensation consultants, legal counsel and other advisors.

In December 2019, the HR&C Committee reviewed the HR&C Committee Charter and made recommendations to update it in accordance with best practices and to, among other things, supplement the HR&C Committee’s responsibilities to oversee the Director remuneration every two years and CEO emergency succession planning. These recommendations were approved by the Board on December 10, 2019. In connection with the listing of the Common shares on the NYSE on February 1, 2021, the Company revised the HR&C Committee Charter on February 11, 2021 to address certain NYSE requirements. Further amendments related to the NYSE listing were also made on December 7, 2021. The HR&C Committee Charter may be viewed on our website at www.westfraser.com.

Orientation Program and Continuing Education

New Directors receive a broad range of materials that provide both historical and forward-looking information concerning West Fraser, its operations, senior management and the Board, and its strategic objectives. As part of our orientation program, new Directors have an opportunity to meet with senior management to discuss our business, receive historical and current operating and financial information and

64

are encouraged to tour our facilities. Directors have access to an archive of Board materials, including management presentations from prior meetings. In addition to the formal orientation and continuing education programs, in connection with the appointment of Marian Lawson and Colleen McMorrow, the Governance Committee implemented a custom program for their orientation including an overview of the Company’s key policies, codes and mandates and briefings on the Company’s operations, business and key issues. A similar customized orientation program was also developed and implemented for Ellis Ketcham Johnson by the Governance Committee. In connection with the appointment of new Directors, the Governance Committee will develop and implement similar orientation programs customized for each candidate’s skills and experience.

We regularly provide and organize continuing education programs for all Directors. Our continuing education programs include regular presentations by senior executives about emerging issues, risks and topics relevant to our business and operations and the regulatory environment, as well as information packages developed to enhance the Director’s understanding of the subject matter. Furthermore, special subjects are also covered with a view to keeping the Directors informed and up to date in relation to industry developments, new legislation that affects operations and distribution, major files and projects, as well as economic, political, sustainability and ESG trends. External experts are also invited from time to time to speak on various topics. Committee chairs may also coordinate education sessions on specific topics for their Committee members.

The continuing education sessions and presentations by our senior executive and external experts to our Board during 2021 and 2022 included the following subject matter and topics:

Board proceedings also include regular review of risk factors including detailed reviews of focus risks and periodic presentations by management and outside industry experts on important and evolving issues. Directors also visit and tour certain of our facilities on a regular basis which contributes to a more complete understanding of our business. Site visits also give Directors an opportunity to meet directly with management and other employees in those areas or regions.

Each of our Directors has had, or currently has, executive or Board of Director responsibilities and there is a regular sharing of those experiences, which assists our Board in identifying and adopting, on a continuing basis, best corporate governance practices.

A key part of each regularly scheduled Board meeting is a business overview provided by the CEO. This overview includes an operational and financial review, but also provides perspectives on growth strategies, human resources, political, legal and regulatory issues and material changes in our risk environment. These discussions help our Directors to understand the full scope of our underlying business environment when making decisions that affect our future.

We also encourage individual Directors to participate in outside professional development programs. We pay for these expenses as long as the Chair of the Board and the Chair of the Governance Committee approve the program in advance. They are also provided with corporate subscriptions to certain relevant industry publications. All of our Directors are members of the Institute of Corporate Directors (“ICD”), which provides continuing education for directors through publications, seminars and conferences.

On an ongoing basis, the Company:

• ensures that Directors have timely access to materials and information required to properly discharge their responsibilities;

• maintains a secure Directors’ portal for prompt dissemination of information and provides published information, industry publications, articles of interest and other relevant materials to Directors in between meetings; and

• canvasses Directors for suggestions as to topics and issues for which they would like to receive a presentation, briefing or report.

Individual Directors attended and, in some cases, were participants or presenters at, third party conferences, seminars, webinars and presentations on a broad range of topics in 2020, 2021 and 2022, including the following:

EXECUTIVE COMPENSATION DISCUSSION & ANALYSIS

Human Resources & Compensation Committee Responsibility

The HR&C Committee is responsible for recommending to the Board the level and nature of compensation for executive officers and Directors and may grant Options to officers and employees under the Stock Option Plan, although in practice the Board provides final approval of all compensation matters for Directors and executive officers, including Option grants. In making its determinations, the HR&C Committee has access to comparative data and, if considered appropriate, receives advice from selected independent consultants.

The HR&C Committee is also responsible for reviewing and recommending to the Board the approval of our compensation and benefits (including retirement and pension) philosophy and policies and any incentive compensation plans and equity based plans and assessing on an ongoing basis whether such compensation and benefits policies are consistent with the sustainable achievement of our business objectives, the prudent management of our operations and risks, and the promotion of adherence to our

68

Code of Conduct, its policies concerning safety and environmental stewardship and other material policies, procedures and controls. In reviewing such policies, the HR&C Committee may consider the recruitment, development, promotion, retention and compensation of executive management and other employees and any other factors that it deems appropriate.

The HR&C Committee also ensures that such compensation and benefit policies do not encourage unwarranted risk taking and undertakes annual risk assessments of these policies either through regular independent or internal reviews of material compensation -related risks. When it reviews and recommends compensation for the CEO and executive management, the HR&C Committee assesses the appropriateness of compensation relative to business risks undertaken by considering, among other things, adherence to our Code of Conduct and other material policies, procedures and controls, as well as any other factors it considers appropriate.

The HR&C Committee is also responsible for overseeing the financial position, governance, administration and compliance with statutory and regulatory requirements of the Company’s pension plans and reporting to the Board annually on these plans. The HR&C Committee also oversees talent development and succession planning for our executive management and annually reports to the Board on such planning.

Composition of the HR&C Committee

The HR&C Committee currently consists of five independent Directors, each of whom has held senior executive roles that have included involvement in executive compensation issues. The HR&C Committee met three times in 2022 to review matters relating to the compensation of executive officers. In addition to meetings, members of the HR&C Committee regularly receive reports and advice from independent consultants and members of executive management on executive compensation issues. None of the members of the HR&C Committee is indebted to the Company.

See also “Human Resources & Compensation Committee”.

Report on Executive Compensation

The policy of the HR&C Committee and the Board with respect to executive compensation is to provide compensation to each executive officer in the form of a base salary, employment benefits, performance related bonus, equity based long-term incentives and postretirement pension benefits in order to attract and retain a highly motivated, cohesive and results oriented management team. Total compensation for each executive officer (inclusive of long-term incentives and post-retirement pension benefits) is designed to be competitive with that provided by comparable companies in Canada to executive officers in similar positions as well as to align the interests of executive officers with those of our Shareholders and not encourage excessive risk taking. Each of the components of total compensation is established based on the following criteria:

Base Salary	–	to be at or below the median base salaries for comparable positions
Annual Incentive Bonus	–	based on our financial performance above a minimum return on shareholders’ equity, and targeted to be at or below the median for comparable positions
Long Term Incentive	–	to be above the median on long term incentives for comparable positions

Overall, the total compensation package (including long-term incentives and post-retirement pension benefits) is designed to compensate executive officers for above average, long-term, sustainable financial

69

results, and is designed to be competitive at the 50^th percentile for overall compensation for comparable positions.

In order to establish compensation for executive officers other than the CEO, the HR&C Committee receives recommendations with supporting documentation, including data on comparable compensation levels, from the CEO. The HR&C Committee considers the recommendations and comparative data and makes its recommendation to the Board. In respect of compensation for the CEO, the HR&C Committee bases its recommendation to the Board on its review of comparable compensation data for chief executive officer positions. In 2018, as part of its review the HR&C Committee considered a survey and report prepared by Willis Towers Watson (“Towers Watson”), a professional services firm, of our executive compensation program relative to those of different peer groups, which included a review of the compensation for the CEO and our other executive officers and comparable compensation data for chief executive officer and other executive officer positions of those peers. In 2021, the HR&C Committee updated its review and considered an updated survey and report prepared by Towers Watson of our executive compensation program relative to those of different peer groups.

In determining the comparability of similar positions in other companies, the HR&C Committee considers responsibility levels as well as industry similarity, annual revenues and cash flows, total assets, market capitalization and number of employees of the selected companies. For positions where compensation data is not comparable, internal guidelines and data are used.

The Company uses, and periodically participates in, broad-based compensation surveys prepared by independent consulting firms. As well, from time to time, the Company and the HR&C Committee may obtain specific benchmarking data prepared by independent consulting firms. This information, along with Company specific data, is considered when establishing compensation for executive officers.

In connection with the updated survey and report prepared in 2021 by Towers Watson of our executive compensation program relative to those of different peer groups, and on the recommendation of Towers Watson, the peer group for the compensation benchmarking study was updated in 2021 and is currently comprised of the publicly traded, Canadian and U.S. companies set out in the table below. Prior to the adoption of the updated peer group, the compensation peer group was based on the peer group in the 2018 survey and report and recommendation of Towers Watson.

Paper and Forest Products	Capital-Intensive
Resolute Forest Products Inc.	Finning International Inc.
Canfor Corporation	Gibson Energy Inc.
Cascades, Inc.	Keyera Corp.
Louisiana-Pacific Corporation	Methanex Corporation
Interfor Corporation	Parkland Corporation
Boise Cascade Company	WSP Global Inc.

Base Salaries

The HR&C Committee reviews executive management base salaries periodically and considers annual adjustments to be effective in October of each year. The most recent review of base salaries was conducted in September 2022.

In determining its September 2022 recommendations for the base salary of each executive officer, the HR&C Committee considered the comparative data for the peer group.

Annual Incentive Bonus Plan

The annual incentive bonus plan (the “Bonus Plan”) covers our CEO and our Vice-Presidents. The Bonus Plan is the variable compensation component of total executive compensation designed to compensate these officers annually based on the achievement of our objective annual financial return targets.

The annual bonus is calculated as a percentage of current base salary, with the percentage earned based on the adjusted net income (adjusted to exclude equity-based compensation expense or recovery and any accrual for bonuses to our senior executives, both on an after-tax basis) divided by average Shareholders’ equity (“ROSE”). If the ROSE for the year is below 5% for the applicable year, no bonuses are payable under the Bonus Plan. At the 5% ROSE level, bonuses for the Vice-Presidents are earned at 17.5% of base salary. The bonus percentage increases as the ROSE increases, and the bonus percentage earned will reach 100% of base salary at a 15% ROSE level, which is the maximum bonus percentage payable. The bonus percentage for the CEO is equal to 150% of the bonus percentage for other officers covered by the Bonus Plan for bonuses earned in 2022 and later years, and was 125% prior to 2022.

The Board may, in its discretion, also consider other issues, including safety and environmental performance, when determining the amount, if any, of bonuses earned under the Bonus Plan that will be paid.

In 2022, our earnings were $1,974 million, which resulted in an annual ROSE of 24.4% for 2022. This exceeded the bonus threshold and annual incentive bonuses of 100% of the base salary were awarded to the qualifying senior executives in accordance with the Bonus Plan (with the bonus percentage for the CEO equal to 150% of such bonus percentage) and were paid in 2023. In 2021, on an adjusted basis (adjusted by excluding equity-based compensation expense or recovery and any accrual for bonuses to our senior executives, both on an after-tax basis) our earnings were $2,947 million, which resulted in an annual ROSE of 42.4% for 2021. This exceeded the bonus threshold and annual incentive bonuses of 100% of the base salary were awarded to the qualifying senior executives in accordance with the Bonus Plan (with the bonus percentage for the CEO equal to 150% of such bonus percentage) and were paid in 2022. In 2020, the annual ROSE was 29% which exceeded the bonus threshold and annual incentive bonuses of a maximum of 100% of base salary were awarded to each of the qualifying senior executives in accordance with the Bonus Plan (with the bonus percentage for the CEO equal to 125% of such bonus percentage) and were paid in 2021. See also “Clawback Policy” which applies to the Bonus Plan.

Long-Term Incentive Component

The long-term incentive component of compensation is comprised of Options and phantom share units (which are either RS Units or PS Units) that are intended to directly align the long-term interests of our senior management with those of our Shareholders. The proportion of Options and phantom share units included in a long-term incentive grant will vary from time to time at the discretion of the Board. In 2019, the Board, on the recommendation of the HR&C Committee, changed the mix of the long-term incentive components of executive compensation to eliminate grants of RS Units and grant additional PS Units in their place in order to increase the award of performance-conditioned equity incentive components of executive compensation. As a result, approximately 50% of the value of the long-term incentives granted in 2022 and 2021 to executive officers (which consisted of only Options and PS Units) are performance-conditioned.

Stock Option Plan

The Board established the Stock Option Plan on February 24, 1994 as a means of recognizing contributions to the Company made by Directors, officers and employees and to provide a long-term incentive for their

71

continuing relationship with the Company and its subsidiaries. Directors ceased to participate under the Stock Option Plan in 2004. The Stock Option Plan has been amended from time to time. In February of 2021, the Stock Option Plan was amended to increase the number of Common shares that may be issued in respect of Options granted under it, to impose certain limits on the number of Options that may be issued to our insiders, to establish certain restrictions on amendments to the Stock Option Plan without Shareholder approval, to provide for certain automatic extensions for Options expiring during or within five business days of a blackout period under the Company’s Securities Trading Policy, and to address certain incidental housekeeping changes. In February of 2022, the Stock Option Plan was amended to provide that the cash value is determined using the VWAP as at the trading day prior to the date of exercise.

In addition, the Company has adopted Replacement Option Plans in connection with the Norbord Acquisition, pursuant to which the Company has issued Replacement Options. The Replacement Options carry substantially the same terms as the original Norbord Options, except that they are exercisable into Common shares and have been adjusted in accordance with the Exchange Ratio. The Replacement Option Plans exist solely to grant and administer the Replacement Options and did not require Shareholder approval under the policies of the TSX, as the aggregate number of Common shares issuable under them is less than 2% of the number of Common shares issued and outstanding prior to the Norbord Acquisition. Upon the exercise or expiry of all Replacement Options, the Replacement Option Plans will be terminated. See also “Option Grants”.

Notes:

1. As at the Record Date, December 31, 2022, December 31, 2021 and December 31, 2020, respectively.

2. Includes 862,192 under the Stock Option Plan and 104,149 under the Replacement Option Plans.

3. Includes 728,381 under the Stock Option Plan and 112,934 under the Replacement Option Plans.

4. Includes 791,617 under the Stock Option Plan and 286,223 under the Replacement Option Plans. No new Replacement Options may be granted under the Replacement Option Plans and they will be terminated when all Replacement Options are exercised or expire.

5. At the special meeting of Shareholders held on January 19, 2021, the Shareholders approved an increase of 1,000,000 Common shares to the maximum number of Common shares that may be issued on the exercise of Options under the Stock Option Plan.

Annual Burn Rate

The following table summarizes the burn rate during the last three fiscal years. Burn rate is defined as the total number of Options granted during the applicable fiscal year divided by the weighted average number of Common shares and Class B Shares outstanding for the applicable fiscal year.

72

	Options Granted in Year	Net Burn Rate1	Burn Rate2	Weighted average number of securities outstanding
2022	124,566	0.1%	0.1%	94,173,000
2021	171,975	0.1%	0.2%	109,020,975
2020	157,685	0.2%	0.2%	68,671,747

Notes:

1. Number of Options granted in a fiscal year, minus expired Options, divided by the weighted average number of Common shares and Class B Shares outstanding for the applicable fiscal year.

2. Number of Options granted divided by weighted average number of Common shares and Class B Shares outstanding for the applicable fiscal year.

Since the introduction in 2003 of the right of a holder to surrender an Option for a cash payment (the “Cash Value Alternative”) under the Stock Option Plan, as at the Record Date, 219,918 Options have been exercised for Common shares under the Stock Option Plan, resulting in a 0.26% dilution to Shareholders (as adjusted to reflect the Stock Dividend). During the financial year ended December 31, 2022, no Options were exercised for Common shares under the Stock Option Plan or under the Replacement Option Plans. See “Option Grants”. Of the 966,341 outstanding Options, 521,481 are exercisable and, of the outstanding Options, 780,200 Options were held by insiders, representing 0.9% of the total number of issued and outstanding Common shares and Class B Shares, in each case as of the Record Date.

A total of 124,566 Options were granted to officers or employees in 2022 representing 0.15% of the total number of issued and outstanding Common shares and Class B Shares as at the end of 2022, and a total of 137,115 Options were granted to officers or employees in February 2023, representing 0.16% of the total number of issued and outstanding Common shares and Class B Shares as of the Record Date.

Our Board has adopted a policy to manage the Stock Option Plan with a goal of limiting the potential dilution of outstanding and remaining authorized Options to 10% or less of the number of our outstanding Shares. The aggregate potential dilution of all issued and authorized Options under our Stock Option Plan was 2.0% at the Record Date and the aggregate potential dilution of all issued and authorized Options under our Stock Option Plan together with all outstanding Replacement Options under the Replacement Option Plans was, 2.1% at the Record Date.

Phantom Share Unit Plan

In 2010, the Board approved the Phantom Share Unit Plan, which is intended to supplement, in whole or in part, the granting of Options as long term incentives for officers and employees. This plan provides contingent future compensation based on Common share price performance but is payable only in cash and represents no potential for Shareholder dilution. The HR&C Committee and the Board believe that this Phantom Share Unit Plan, combined with other components of compensation, provides a broader range of alternatives in developing retention and performance incentives for officers and employees that more directly align their interests with those of current and future Shareholders.

The Phantom Share Unit Plan permits the Board to grant, as it determines appropriate, two types of units, RS Units and PS Units, which vest on the third anniversary of the grant date. A vested RS Unit must be redeemed by us by payment to the holder of an amount equal to the VWAP of a Common share over the 20 trading days immediately preceding its vesting date (the “Vesting Date Value”). A vested PS Unit must be redeemed by us by payment to the holder of an amount, determined by the Board, that is equal to or between nil and twice its Vesting Date Value based on two performance criteria measuring our performance relative to the performance of a peer group of companies over the three-year performance period. At the end of such period, in order to determine the amount to be paid on vested PS Units, the Company’s

73

performance is measured by reference to (i) the Company’s cumulative total Shareholder return (the “TSR”) relative to the TSR of the peer group, and (ii) the Company’s average annual return on capital employed (“ROCE”) relative to the ROCE of the peer group over the three-year performance period. The amount paid, if any, on such PS Units is based on an equal weighting of these two performance measurements, although if the ROCE is negative for the performance period, the weighting for that factor is capped at one half its potential maximum, regardless of relative performance. The peer group used for the purposes of the Phantom Share Unit Plan for PS Units granted prior to February 17, 2022 consists of Canfor Corporation, Interfor Corporation, Western Forest Products Inc. and Weyerhaeuser Company, all of which are North American publicly traded forest products companies. On the recommendation of the HR&C Committee, this peer group may be reviewed and changed by the Board, from time to time, as it deems appropriate. The Board also has discretion to vary the payout calculation as it considers appropriate to take into account factors that may have a significant or extraordinary effect on relative performance.

Officers and employees granted phantom share units under the Phantom Share Unit Plan are also entitled to additional phantom share units to reflect cash dividends paid on Common shares from the applicable grant date until payout. The final amount to be paid, in cash, to each officer or employee on RS Units and PS Units is based on the type and number of vested phantom share units they hold, multiplied by the applicable payout value. Other than officers or employees who retire, become totally disabled or die, phantom share units will be automatically cancelled, without payout, on termination of employment or resignation. In the event of retirement, total disability or death of a holder of RS Units or PS Units granted after 2012, the number of phantom share units held will be reduced based on the proportion of the three year period that the holder was not an officer or employee.

In February 2022, the Board made a number of amendments to the Phantom Share Unit Plan including (a) updating the peer group to remove Western Forest Products Inc. and add Resolute Forest Products Inc. and Louisiana – Pacific Corporation, (b) providing that for U.S. residents units may be issued and cash settled in U.S. dollars with the fair-market value on settlement referencing the VWAP on the NYSE, and (c) providing that cash value on settlement and value for dividend entitlements is to be determined using a single day VWAP as at the prior trading day. In February 2023, the Board further amended the peer group for grants after February 14, 2023 to remove Resolute Forest Products Inc. and add Potlach Deltic.

Beginning in 2020, the Board has granted only PS Units under the Phantom Share Unit Plan to executive officers and employees, and no RS Units have been granted. The change in 2020 in the mix of phantom share units granted was made to increase the award of performance-conditioned long-term incentives granted to executive officers and employees and reduce the award of time-conditioned incentives. As a result, since 2020, approximately 50% of the value of the long-term incentives granted to executive officers and employees (which in both cases consisted of only Options and PS Units) are performance-conditioned. See also “Clawback Policy”, which applies to the Phantom Share Unit Plan.

For PS Units which vested in February of 2023, the relative performance multiplier was 2.0. The calculation is set out below.

PS Unit Relative Performance Multiplier

First Comparison (out of a maximum of 1.00) – Return on Capital Employed (“ROCE”), annual average of calendar years, 2020, 2021 and 2022:

2021	1.83
2022	1.25

Norbord RSU Plan and DSU Plans

In addition, in connection with the Norbord Acquisition, the Company assumed Norbord’s obligations under the Norbord RSU Plan and the Norbord DSU Plans with respect to the Norbord RSUs held by Norbord Continuing Executives who are continuing and with respect to all outstanding Norbord DSUs.

Norbord RSUs held by Norbord Continuing Executives outstanding immediately prior to the closing of the Norbord Acquisition remained outstanding on their existing terms following completion, except that the number of such Norbord RSUs were adjusted by the Exchange Ratio and are to be paid out in reference to Common shares in accordance with the terms of the Norbord Acquisition. No new Norbord RSUs were issuable under the Norbord RSU Plan following completion of the Norbord Acquisition. As at February 4, 2023, all of the outstanding Norbord RSUs vested and, upon settlement the Norbord RSU Plan terminated.

All Norbord DSUs outstanding immediately prior to the closing of the Norbord Acquisition remained outstanding on their existing terms following the completion of the Norbord Acquisition, except that the number of such Norbord DSUs were adjusted by the Exchange Ratio and are to be paid out in reference to Common shares in accordance with the terms of the Norbord Acquisition. No new Norbord DSUs may be issued under the director Norbord DSU Plan following completion of the Norbord Acquisition. Both the management Norbord DSU Plan and the director Norbord DSU Plan will remain in place to administer Norbord DSUs outstanding thereunder until such time as all outstanding Norbord DSUs are settled, at which point the Norbord DSU Plans will be terminated.

In February 2022, the Board amended the Norbord RSU Plan and the Norbord DSU Plans to provide that cash value on settlement and value for dividend entitlements is to be determined using a single day VWAP as at the prior trading day.

Post-Retirement Pension Benefit

Most executive officers, including the CEO, are members of our non-contributory defined benefit pension plans for salaried employees. Certain executive officers are members of our defined contribution and 401K pension plans. The pension benefit provided under these pension plans is described under “Pension Plans” of this Circular. The Company does not provide any additional post-retirement benefits, such as medical or dental insurance, to the executive officers.

75

Clawback Policy

We have recognized a trend in recent years towards the adoption of recoupment and “clawback” policies, particularly among large public companies. As a prudent aspect of risk management and our commitment to operate consistently with good governance practices, the Board, in 2013, approved amendments to the Phantom Share Unit Plan and the Bonus Plan to incorporate payment adjustment provisions. These plans now both contain financial restatement triggers, permitting West Fraser to recoup the amount of the incentive awards that have been paid in excess of the amount that would have been payable under the restated financial statements, or deduct such excess amount from future payments to be made under such plans. These payment adjustment provisions also allow the Company to adjust incentive awards upwards to reflect restated financial statements that are more favourable than the original financial statements. The payment adjustment provisions have a three-year look-back period.

CEO’s Compensation

In recommending compensation for the CEO, the HR&C Committee follows similar principles to those applied for all of our other executive officers. The HR&C Committee considers market competitive salary information for chief executive officer positions in similar sized companies in Canada and the U.S. This includes manufacturing companies in other sectors as well as in the forest products sector. The Company periodically participates in broad based compensation surveys and also periodically seeks the advice of independent compensation consultants engaged to review the executive compensation program. In 2021, Towers Watson conducted a survey and review of our executive compensation program relative to those of different peer groups. The survey and review results, along with Company specific data, are used to determine the competitiveness of the CEO’s compensation and its alignment with the interests of Shareholders. The CEO establishes, with guidance and direction from the Board, annual goals and reports to the Board at the end of each year on his performance against those goals. The HR&C Committee considers this performance when considering its recommendation of compensation of the CEO.

Details of our CEO’s compensation are described in the table titled “Summary Compensation Table”.

Executive Equity Holding Requirements

In February 2013, our Board approved the adoption of minimum equity holding requirements, which were subsequently amended in September 2013. The minimum equity holding requirements are reviewed from time to time to align with what the Board considers best governance practices. In February 2019, on the recommendation of the HR&C Committee, the Board adopted a new equity holding requirements policy (the “Equity Holdings Requirements Policy”) to take into account changes to the Company’s equity compensation practices, which eliminated grants of RS Units and replaced them with grants of additional PS Units (which do not qualify as eligible equity under the Policy) to increase the award of performance-conditioned equity incentive components of executive compensation. As a result of these changes, beginning in 2020 approximately 50% of the value of the long-term incentives granted to executive officers (which consisted of only Options and PS Units) are performance-conditioned.

Under the Equity Holding Requirements Policy, each executive officer is required to hold Shares and RS Units having a value of not less than the executive’s base salary in the case of Senior Vice-Presidents and Vice-Presidents and not less than three times the executive’s base salary in the case of the CEO. Shares and RS Units held by an executive officer will be valued based on the greater of (1) their original cost or grant date value and (2) December 31 of the most recently completed financial year (or, if such date is not a trading date, on the last trading date of such year).

76

Initially, executive officers had until January 1, 2018, or if appointed after 2013, five years from the date of their appointment to meet the minimum equity holding requirements. In connection with changes to the long-term incentive components of executive compensation in February 2019, the Chief Executive Officer and Senior Vice-Presidents have five years from the later of the date of adoption of the new Equity Holding Requirements Policy in February 2019 and the date of such officer’s appointment to meet the minimum equity holding requirements, provided that officers who did not meet the requirements on such date must acquire not less than a pro-rata amount of equity each year to achieve full compliance by the end of such five year period. In connection with amendments to the Company’s Equity Holding Requirement Policy in September 2022, Vice-Presidents that are not Senior Vice-Presidents, were permitted to have eight years from the later of the date of adoption of the new Equity Holding Requirements Policy in February 2019 and the date of such officer’s appointment to meet the minimum equity holding requirements, provided that Vice-Presidents who did not meet the requirements on such date must acquire not less than a pro-rata amount of equity each year to achieve full compliance by the end of such eight year period.

Independent Consultant

Compensation Advice

Towers Watson has provided consulting services to us for several years with respect to executive and nonexecutive compensation. In 2012, the HR&C Committee adopted a protocol under which all consulting services provided by Towers Watson related to executive compensation must be retained and authorized by the HR&C Committee. Towers Watson reports to the HR&C Committee as its outside compensation consultant to advise on compensation policies, including providing information on comparative levels of compensation for our senior executives and Directors. In 2021, Towers Watson conducted a survey and review of our executive compensation program relative to those of different peer groups and to assess market competitiveness of our executive compensation programs and provided advice on executive compensation.

Compensation Risk Assessment Advice

In 2022, the Company engaged Towers Watson to provide advice and to update its compensation risk assessment report to the HR&C Committee, The compensation risk assessment report concluded that there did not appear to be significant risks arising from the Company’s compensation policies and practices that were likely to have a material adverse effect on the Company. In its updated assessment and reports, Towers Watson also took into account and considered the limited compensation related risks within the Company, the involvement and authority of the Board in both compensation and risk management oversight, the presence of effective risk mitigating practices in the design of compensation programs and the changes to the long-term executive incentive compensation mix that place a greater emphasis on performance-conditioned long-term incentive grants.

Fees

The following table shows the fees paid to Towers Watson for services provided in the last two fiscal years:

Executive Compensation

Total compensation for Named Executive Officers, as described in the Summary Compensation Table set out below, reflects a gradual recovery from the significant downturn in the forest products industry that began in 2006. Annual incentive bonuses for Named Executive Officers will be earned in those years where the Company achieves a ROSE in excess of the minimum threshold, with payment occurring in the following year. The minimum ROSE threshold was not met in 2015 and no annual incentive bonuses were earned by the senior executives, including the Named Executive Officers. In 2016, 2017 and 2018 the minimum ROSE threshold was exceeded and annual incentive bonuses were earned, with payment occurring in each of the following years. The minimum ROSE threshold was not met in 2019 and no annual incentive bonuses were earned by the senior executives, including the Named Executive Officers. In 2020, 2021 and 2022 the annual minimum ROSE threshold was exceeded and the maximum annual incentive bonuses were earned by the senior executives, including the Named Executive Officers, which were paid out in 2021, 2022 and 2023 respectively. See also “Annual Incentive Bonus Plan”.

The compensation of each of our Named Executive Officers for our three most recently completed financial years is set out below:

Notes:

1. For a description of the units see “Phantom Share Unit Plan”. Units are valued at the date of grant using the Towers Watson Binomial method, which was the method used by the HR&C Committee when granting the units. This method was applied consistently in its competitive market analysis.

2. Options have a term of ten years and vest as to 20% on each of the first through fifth anniversary dates of the grant date. Each Option was valued using the Towers Watson Binomial method for the same reason as described in footnote 1. Whether the executive will receive value under these Options will depend on the future market price of Common shares. A description of the current value of all Options held by each Named Executive Officer is set out in the charts under “Summary of Outstanding Options”.

3. Annual incentive (bonus) plan payments are included in the year earned and are paid in the following year.

4. Pension values for Messrs. Ferris, Virostek, and McLaren represent the change in the defined benefit pension liability related to the annual service cost, actual and assumed future compensation changes, including the impact of plan changes, if any. The defined benefit pension value is calculated based on the Company’s best estimate of future events that affect pension liabilities, including assumptions about future salary adjustments and bonuses, and is reflected in the pension value for the Named Executive Officers. Defined benefit pension values will increase in those years where there has been a significant salary increase. Defined benefit pension values will also be affected by changes in future compensation assumptions and in particular in those years where such assumptions have been updated following periodic reviews of the underlying pension plans and their associated liabilities. Pension value for Ms. Lampard and Mr. Burke represents the Company’s basic

81

and matching contributions under the defined contribution pension plan. Mr. Burke’s value has been converted into Canadian dollars using the Bank of Canada’s average US/CDN exchange rate for the fiscal year (2022 = 1.3013; 2021 = 1.2520)

5. Perquisites and other personal benefits that exceed the lesser of $50,000 and 10% of total compensation for any of our Named Executive Officers.

6. Mr. McLaren was appointed as the Chief Operating Officer on December 7, 2021 and previously served as President, Solid Wood. During the three-year period reported in the table above, Mr. McLaren’s salary and annual incentive compensation was awarded in U.S. dollars. The exchange rate used to convert this U.S. dollar compensation was the Bank of Canada’s average US/CDN exchange rate for the fiscal year (2022 = 1.3013; 2021 = 1.2520; and 2020 = 1.3405;).

7. Ms. Lampard and Mr. Burke joined West Fraser on February 1, 2021 and were previously Senior Vice-President and CFO and Senior Vice-President, North American Operations respectively, of Norbord until February 1, 2021. Ms. Lampard’s and Mr. Burke’s 2020 and January 2021 compensation was earned at Norbord and not presented in the table Mr. Burke is paid in U.S. dollars. The exchange rate used to convert this U.S. dollar compensation was the Bank of Canada’s average US/CDN exchange rate for the fiscal year (2022 = 1.3013; 2021 = 1.2520)

Option Grants

Description of West Fraser Stock Option Plan

Under the Stock Option Plan, the exercise price of an Option per Common share will not be less than the Closing Price on the last trading day before the Option is granted. The length of the term of Options will be fixed by the Board or the HR&C Committee at not more than ten years and, unless otherwise determined by the Board or the HR&C Committee, Options vest at the rate of 20% per year over the first five years of the term.

Under the Stock Option Plan, Options may not be exercised after a holder ceases to be an eligible participant, except that (a) an Option held on the death of an Option holder may be exercised by the personal representative of the holder during the period ending on the earlier of its expiry date and two years after the date of death, (b) an Option held on the retirement or total disability of an Option holder may be exercised during the period ending on the earlier of its expiry date and five years after the date of retirement or disability, and (c) a vested Option held in any other case may be exercised no later than the earlier of its expiry date and 30 days after the date the holder ceases to be an eligible participant. Options are not assignable, other than those that may be exercised by the personal representative of a deceased holder. We do not provide any financial assistance to holders of Options in connection with the exercise of Options.

The number of Common shares subject to an Option, the exercise price per Common share and the total number of Common shares that may be made subject to Options under the Stock Option Plan will be adjusted proportionately in the event of any subdivision or consolidation of Common shares or any dividend payable in Common shares and will be adjusted as determined by the Board in the event of certain other reorganizations or other events affecting the Common shares. Under the Stock Option Plan, Options granted that have not vested do not automatically vest on a change of control.

The Stock Option Plan permits outstanding vested Options to be surrendered by the holder to the Company in return for a cash payment under the Cash Value Alternative. The cash payment for a surrendered Option is equal to the amount by which the weighted average price per share at which the Common shares were traded on the TSX on the last trading day exceeds the exercise price per Common share applicable to the Option multiplied by the number of Common shares underlying the Option and the amount determined by the HR&C Committee as representative of the estimated costs avoided by the Option holder (such as trading commissions) by virtue of electing the Cash Value Alternative. Since implementation of the Cash Value Alternative in 2003, only 219,535 Common shares have been issued on the exercise of outstanding Options under the Stock Option Plan. Since February 1, 2021, an additional 73,452 Common shares have been issued on the exercise of outstanding Replacement Options. Our management believes that the Stock Option Plan, with the Cash Value Alternative, operates in a manner similar to the types of long-term incentive plans currently recommended by major institutional shareholder groups for public companies in North America.

82

The Stock Option Plan restricts the Option holdings of insiders. It provides that: (a) annual grants of Options to insiders may not be for a number of Common shares that exceeds 1% of the total number of our outstanding voting securities (the “Issued Shares”); (b) no single insider may hold, at any time, Options to acquire a number of Common shares that, together with all other Common shares issuable to the insider under any other equity compensation arrangements then in place (“Other Arrangements”), would exceed 5% of the Issued Shares; (c) the total number of Options held, at any time, by insiders cannot allow them to acquire a number of Common shares that, together with all other Common shares issuable to insiders under any Other Arrangements, would exceed 10% of the Issued Shares; and (d) the number of Common shares that may be acquired by all insiders during any 12-month period by exercising Options, together with all other Common shares issuable to insiders under any Other Arrangements, may not exceed 10% of the Issued Shares.

The Board has the power, without Shareholder approval, to amend, suspend, terminate or discontinue the Stock Option Plan, provided that doing so will not adversely alter or impair any Option without the written consent of the holder. This power includes the right to make appropriate adjustments to outstanding Options in the event of certain corporate transactions, to add provisions requiring forfeiture of Options in certain circumstances, to specify practices with respect to applicable tax withholdings, and to enhance clarity or correct ambiguous provisions in the Stock Option Plan. Notwithstanding this power, the Stock Option Plan provides that the Board may not, without Shareholder approval, amend the Stock Option Plan or an Option to: (i) increase the number of Common shares that may be issued; (ii) reduce the subscription price of an outstanding Option; (iii) extend the term of any Option beyond its expiry date or allow for an expiry date to be greater than ten years; (iv) allow non-permitted assignments or exercises of Options; (v) expand the persons entitled to participate in the Stock Option Plan; or (vi) provide for other types of equity based compensation.

In 2007, we obtained the approval of our Shareholders to make certain amendments to the Stock Option Plan which included, amending the amendment provision to specify the circumstances in which Shareholder approval is or is not required for an amendment to the Stock Option Plan. In 2008 and 2010, our Board made housekeeping amendments to the Stock Option Plan to (i) clarify provisions related to retirement, disability or death, and (ii) clarify provisions related to withholding taxes, respectively.

In 2016, we obtained approval of our Shareholders to amend the Stock Option Plan to increase by 750,000 the number of Common shares that may be issued under Options and to restrict other forms of amendment without Shareholder approval. At the special meeting of Shareholders held on January 19, 2021 to approve the Norbord Acquisition, the Shareholders approved a further increase of 1,000,000 Common shares to the maximum number of Common shares that may be issued on the exercise of Options under the Stock Option Plan.

On February 15, 2022, the Board amended the Stock Option Plan to provide that (a) cash value would be determined using the VWAP as at the trading day prior to the date of exercise; and (b) for Options granted to U.S. residents, Shares will be issued and cash settled in U.S. dollars with the fair market value on settlement referencing the VWAP on the NYSE.

A total of 124,566 Options were granted pursuant to the Stock Option Plan during the financial year ended December 31, 2022 and an additional 137,115 Options were granted pursuant to the Stock Option Plan in February of 2023.

In the financial year ended December 31, 2022, 351,448 outstanding Options and Replacement Options were surrendered for cash and no outstanding Options and Replacement Options were surrendered for Common shares, respectively, by the Named Executive Officers.

83

Description of Replacement Option Plans

In addition, the Company has adopted replacement option plans (the “Replacement Option Plans”) in connection with the Norbord Acquisition. These Replacement Option Plans exist solely to administer the Replacement Options, and no new Options may be granted thereunder following the completion of the Norbord Acquisition. The adoption of these plans did not require Shareholder approval under the policies of the TSX, as the aggregate number of Common shares issuable under them is less than 2% of the number of Common shares issued and outstanding prior to the Norbord Acquisition. Upon the exercise or expiry of all Replacement Options, the Replacement Option Plans will be terminated.

As at December 31, 2022, 112,934 Common shares were issuable on the exercise of Replacement Options. Of that total 111,911 Common shares are issuable under what was previously the Norbord stock option plan (plus an additional 1,023 options that are subject to the UK Option Sub-Plan), the principal terms of which are set out below.

The exercise price of the Replacement Options was determined by multiplying the exercise price of the Norbord Options by the Exchange Ratio. The Replacement Options generally have a 10-year term and continue to vest under their original terms, being at an annual rate of 20% per year beginning on the first anniversary of the date of grant.

Unless otherwise determined by the Board, an option will expire immediately in the event of resignation or termination of employment with cause, within 90 days of termination of employment without cause, within six months of the death of an option holder, and in accordance with its terms on retirement. Notwithstanding the foregoing, the outstanding Norbord Options held by certain option holders will immediately vest in the event such option holders are terminated without cause or constructively dismissed within 24 months of the completion of the Norbord Acquisition.

Certain of the Replacement Options are subject to a UK Option Sub-Plan, which provides for options up to £30,000 in value (based on grant price) to receive capital gains tax treatment for each UK option recipient. The UK Option Sub-Plan provides for the issuance of options under the more restricted terms required by HM Revenue and Customs (UK) to qualify the options for such treatment.

Shareholder approval is required in respect of any amendment to the Replacement Option Plans that would: (a) increase the maximum number of Common shares issuable under such plans (other than on a corporate reorganization); (b) reduce the exercise price of Replacement Options to less than the market price of the Common shares on the date of the option grant; (c) reduce the exercise price of Replacement Options; (d) extend the expiry date for the benefit of an insider; (e) increase the maximum number of Common shares issuable to insiders under the Replacement Option Plans; or (f) amend any of the foregoing limitations.

Pension Plans

The majority of our fulltime salaried employees are covered by non-contributory defined benefit pension plans.

For those salaried employees whose employment began before 2016, the plans provide a pension equal to 2% of the highest average compensation (which includes base salary and bonuses) of the employee for any consecutive 60-month period in that employee’s final 10 years with us, multiplied by the number of years of credited service with us. Normal retirement is at age 65. In accordance with applicable tax legislation, these plans allow for additional years of credited service until a continuing employee reaches age 71. Each of these pension plans allows for early retirement at age 55 with a minimum service requirement of two years. Benefits provided for early retirement are reduced by 4% per year for retirement between the ages of 55 and 57 and by 3% per year for retirement between the ages of 58 and 59. No reduction is made for retirement between the ages of 60 and 64.

On January 1, 2016, we introduced a new non-contributory defined benefit pension plan for salaried employees whose employment begins on or after that date. Changes from the existing plans include a pension based on the employee’s average annual salary over the final 10 years with us, as well as the elimination of early retirement benefits so that full pension benefits are only achieved on retirement at age 65 or over. In accordance with applicable tax legislation, this new plan also allows for additional years of credited service until a continuing employee reaches age 71.

On January 1, 2022 the Canadian salaried defined benefit pension plans closed to new entrants. New salaried employees are enrolled in a defined contribution pension plan with an 8% employer contribution along with 100% matching contributions for the first 3% of employee contributions. At the same time in the US, the 401(k) plan for salaried lumber employees, OSB corporate employees and non-union hourly

89

employees will provide a 3% non-elective retirement contribution, along with 100% matching employer contributions on the first 5% an employee contributes to the plan.

Defined Benefit Pension Plans

The estimated annual pension payable upon retirement under the defined benefit pension plans, assuming employment began before 2016, no reduction for early retirement and based on the standard form life annuity for a minimum of 60 months with no joint survivor pension, is as follows:

Notes:

1. Represents the estimated annual pension, excluding any employee paid ancillary benefits, where applicable, that would be received by the Named Executive Officer upon retirement at age 65 based on actual pensionable earnings at December 31, 2021. The annual pension payable at year end is based on actual credited service at December 31, 2022. The annual pension at age 65 is based on credited service projected to age 65. In accordance with applicable tax legislation, our pension plans allow for additional years of credited service until a continuing employee reaches age 71.

2. The present value is the estimated value of the pension obligation to the date indicated using the actuarial assumptions and methods that are consistent with those used in determining pension liabilities as disclosed in the consolidated financial statements.

3. Compensatory change represents the change in the pension liability related to the annual service cost, actual and assumed future compensation changes and the impact of plan changes, if any. The pension value is calculated based on the Company’s best estimate of future events that affect pension liabilities, including assumptions about future salary adjustments and bonuses, and is reflected in the pension value for the Named Executive Officers. Pension values will increase in those years where there has been a significant salary increase. Pension values will also be affected by changes in future compensation assumptions and in particular in those years where such assumptions have been updated following periodic reviews of the underlying pension plans and their associated liabilities.

4. Non compensatory change includes items such as interest on the obligation and the impact of changes in the discount rate assumption.

The estimated years of credited service under the defined benefit pension plans at the normal retirement age of 65 for each Named Executive Officer is set out below. We have not granted on a discretionary basis any additional years of credited service to our Named Executive Officers in excess of their actual years of service.

91

Name	Estimated Years of Credited Service
Ray Ferris President and CEO	26
Chris Virostek Senior Vice-President and CFO	21
Sean McLaren Chief Operating Officer	45
Kevin Burke Senior Vice-President, Wood Products	Not applicable1
Robin Lampard Senior Vice-President, Finance	102

Note:

1. Mr. Burke is not a member of a defined benefit pension plan.

2. The years of credited service for Ms. Lampard reflect her accrued services in the defined benefit pension plan for Norbord. Ms. Lampard ceased participating in the Norbord defined benefit pension plan effective January 1, 2006 and her service in that plan is frozen at 10 years.

Defined Contribution Pension Plans

The following table shows the value of investments held by the NEOs participating in the Company’s defined contribution pension plans:

Name	Accumulated Value at December 31, 2021 ($)	Total Compensatory Change ($)1	Accumulated Value at December. 31, 2022 ($)
Robin Lampard2 Senior Vice-President, Finance	1,350,149	80,410	1,231,471
Kevin Burke3 Senior Vice-President, Wood Products	1,704,775	83,960	1,607,341

Notes:

1. These amounts represent employer contributions to the Company’s defined contribution pension plans.

2. Ms. Lampard, as a member accruing benefits under the defined contribution pension plan, is no longer eligible to contribute to the flex component of the defined benefit pension plan but has outstanding balances from her participation prior to 2006 that are included in the table.

3. Mr. Burke’s accumulated values and compensatory change have been converted to Canadian dollars. The exchange rate used to convert this U.S. dollar compensation was the Bank of Canada’s average US/CDN exchange rate for the fiscal year (2022 = 1.3013). The accumulated values shown include Mr. Burke’s personal salary and bonus allocation equivalent to $26,676 Canadian into a deferred compensation plan.

Severance and Change of Control Agreements

On November 9, 2020, Norbord entered into a letter agreement with Ms. Lampard, providing for severance entitlements in the event that (i) Norbord (or its successor) or any of its affiliates terminated their employment on a without cause basis or such individual resigns in circumstances constituting constructive dismissal within 24 months following the Norbord Acquisition or other change of control transaction, or (ii) in connection with the consummation of the Norbord Acquisition or other change of control transaction, Norbord (or its successor) or any of its affiliates does not offer such individual a comparable position. Upon such event, the individual is entitled to receive an amount equal to the product of (a) one month per full year of employment with Norbord, and (b) the sum of (i) 1/12th of the individual’s base salary at the rate in effect on the termination date, and (ii) 1/12th the average of the individual’s annual bonus earned in respect of the three most recently completed years prior to the termination date, less all applicable taxes, deductions and withholdings; provided that (a) is no less than 12 months or greater than 24 months. In addition, on November 9, 2020, Norbord entered into a letter agreement with Ms. Lampard, providing that

92

in the event that Norbord (or its successor) or any of its affiliates terminated their employment on a without cause basis or such individual resigns in circumstances constituting constructive dismissal within 24 months following the Norbord Acquisition or other change of control transaction, all the Replacement Options held by them would immediately vest and would be exercisable for 12 months after the termination date and all the Norbord RSUs held by them would also immediately vest and be settled within 30 days following the termination date. The Norbord Acquisition constituted a change of control of Norbord for the purposes of these agreements. On January 18, 2023, the Company and Ms. Lampard agreed to a one-year extension of the foregoing agreements.    

Other than as described above and pension and retirement benefits described elsewhere in this Circular, the Company does not have any agreements with its Named Executive Officers that provide for payments following or in connection with any termination (whether voluntary, involuntary or constructive) or a change in control of the Company.

SHAREHOLDER RIGHTS PLAN AGREEMENT

SHAREHOLDER RIGHTS PLAN AGREEMENT dated as of April 18, 2023 between West Fraser Timber Co. Ltd.

(iii) for a period of 10 calendar days after the Disqualification Date (as defined below), any Person who becomes the Beneficial owner of 20% or more of the outstanding Voting Shares as a result of such Person becoming disqualified from relying on Section 1.1(h)(iv)(B) solely because such Person is making or has announced a current intention to make a Take-over Bid, either alone, through such Person’s Affiliates or Associates or by acting jointly or in concert with any other Person. For the purposes of this definition, “Disqualification Date” means the first date of a public announcement of facts indicating that any Person is making or has announced a current intention to make a Take-over Bid, either alone, through such Person’s Affiliates or Associates or by acting jointly or in concert with any other Person (which, for the purposes of this definition, shall include, without limitation a report asserting such facts filed pursuant to NI 62-103, NI 62-104, Section 13(d) of the U.S. Exchange Act or any other applicable securities laws, as amended from time to time and any provision substituted therefor);

(ii) the denominator is the number of Common Shares per Right that could have been purchased pursuant to Section 3.1(a) in the event that there had been sufficient authorized but unissued Common Shares to permit each holder of a Right (other than an Acquiring Person or a transferee of the kind described in Section 3.1(b)(ii)) to purchase the number of Common Shares to which they would have been entitled under Section 3.1(a)(i);

(c) “Adjustment Factor” shall mean a fraction in which:

In the event that West Fraser determines to maintain Rights in Book Entry Form, it will put in place such alternative procedures as are directed by the Rights Agent for the Rights to be maintained in Book Entry Form (the “Book Entry Rights Exercise Procedures”), it being hereby acknowledged that such procedures shall, to the greatest extent possible, replicate in all substantive respects the procedures set out in this Agreement with respect to the exercise of the Rights Certificates and that the procedures set out in this Agreement shall be modified only to the extent necessary, as determined by the Rights Agent, to permit West Fraser to maintain the Rights in Book Entry Form. In such event, the Book Entry Rights Exercise Procedures shall be deemed to replace the procedures set out in this Agreement with respect to the exercise of Rights and all provisions of this

- 19 -

Agreement referring to Rights Certificates shall be applicable to Rights registered in Book Entry Form in like manner as to Rights in certificated form.

In the event that West Fraser determines to issue a Rights Certificate, it 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, any other Person whose Rights are or become void pursuant to the provisions of Section 3.1(b) 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 West Fraser (West Fraser hereby agreeing to furnish copies of such records to the Rights Agent for this purpose):

(x) a Rights Certificate in substantially the form set out in Attachment 1 hereof, 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 West Fraser 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 judicial or administrative order 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 description of 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. In order for West Fraser to determine whether any Person is holding Common Shares which are Beneficially owned by another Person West Fraser may require such first mentioned Person to furnish such information and documentation as West Fraser deems necessary or appropriate in order to make such determination.

(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 in the manner specified in the Rights Certificate:

(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 or in the form determined appropriate for Rights in Book Entry Form, in either case duly 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

(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 the transfer or delivery of Rights Certificates or the registration, in Book Entry Form, of the Common Shares in a name other than that of the holder of the Rights being exercised.

(e) In the event that West Fraser determines to issue a Rights Certificate, then upon receipt of a Rights Certificate, together with a completed Election to Exercise executed in

- 20 -

accordance with Section 2.2(d)(ii), which does not indicate that such Right is null and void as provided by Section 3.1(b), and payment as set forth in Section 2.2(d)(iii), the Rights Agent (unless otherwise instructed by West Fraser in the event that West Fraser is of the opinion that the Rights cannot be exercised in accordance with this Agreement) will thereupon promptly:

(i) direct the transfer agent to register, in the name of the holder of the Rights being exercised or in such other name as may be designated by such holder, in Book Entry Form the number of such Common Shares to be purchased (West Fraser hereby irrevocably authorizing its transfer agents to comply with all such requisitions);

(ii) when appropriate, requisition from West Fraser the amount of cash to be paid in lieu of issuing fractional Common Shares;

(iii) after receipt of confirmation from the transfer agent that the registration, in Book Entry Form, referred to in Section 2.2(e)(i) has been completed, 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;

(iv) when appropriate, after receipt, deliver the cash referred to in Section 2.2(e)(ii) to or to the order of the registered holder of such Rights Certificate; and

(v) tender to West Fraser all payments received on the exercise of the Rights.

(f) In case the holder of any Rights shall exercise 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 Section 5.5(a)) will be issued by the Rights Agent to such holder or to such holder’s duly authorized assigns.

(g) West Fraser 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 issued upon exercise of Rights shall, at the time of registration in Book Entry Form of such Common Shares (subject to payment of the Exercise Price), be duly authorized, validly issued and fully paid and non-assessable;

(ii) take all such action as may be necessary and within its power to comply with the provisions of Section 3.1 including all actions necessary to comply with the requirements of the BCBCA, the Securities Act (British Columbia), the Securities Act (Ontario), the U.S. Securities Act and the U.S. Exchange 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 principal stock exchanges on which such Common Shares were traded immediately prior to the Stock Acquisition Date;

- 21 -

(iv) pay when due and payable, if applicable, any and all Canadian and United States federal, provincial, state and municipal transfer taxes and charges (not including any income or capital taxes of the holder or exercising holder or any liability of West Fraser to withhold tax) which may be payable in respect of the original issuance or delivery of the Rights Certificates, or the registration in Book Entry Form of Common Shares to be issued upon exercise of any Rights, provided that West Fraser 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 registration in Book Entry Form of Common Shares in a name other than that of the holder of the Rights being transferred or exercised; and

(v) after the Separation Time, except as permitted by Section 5.1, 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 West Fraser shall at any time after the Record Time and prior to the Expiration Time:

(i) declare or pay a dividend on Common Shares payable in Common Shares (or other securities exchangeable for or convertible into or giving a right to acquire Common Shares or other securities of West Fraser) other than pursuant to any Dividend Reinvestment Plan;

(ii) subdivide or change the then outstanding Common Shares into a greater number of Common Shares;

(iii) consolidate or change the then outstanding Common Shares into a smaller number of Common Shares; or

(iv) issue any Common Shares (or other securities exchangeable for or convertible into or giving a right to acquire Common Shares or other securities of West Fraser) in respect of, in lieu of or in exchange for existing Common Shares except as otherwise provided in this Section 2.3,

the Exercise Price and the number of Rights outstanding, or, if the payment or effective date therefor shall occur after the Separation Time, the securities purchasable upon exercise of Rights, shall be adjusted as of the payment or effective date in the manner set forth below. If an event occurs which would require an adjustment under both this Section 2.3 and Section 3.1(a), the adjustment provided for in this Section 2.3 shall be in addition to, and shall be made prior to, any adjustment required under Section 3.1(a).

If the Exercise Price and number of Rights outstanding are to be adjusted:

- 22 -

(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 (or other capital stock) (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; and

(y) each Right held prior to such adjustment will become that number of Rights equal to the Expansion Factor,

and the adjusted number of Rights will be deemed to be distributed 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 (or other capital stock) will have exactly one Right associated with it.

For greater certainty, if the securities purchasable upon exercise of Rights are to be adjusted, the securities purchasable upon exercise of each Right after such adjustment will be the securities that a holder of the securities purchasable upon exercise of one Right immediately prior to such dividend, subdivision, change, consolidation or issuance would hold thereafter after giving full effect to such dividend, subdivision, change, consolidation or issuance.

If, after the Record Time and prior to the Expiration Time, West Fraser shall issue any shares of capital stock other than Common Shares in a transaction of a type described in Section 2.3(a)(i) or (iv), shares of such capital stock shall be treated herein as nearly equivalent to Common Shares as may be practicable and appropriate under the circumstances and West Fraser and the Rights Agent agree to amend this Agreement in order to effect such treatment.

In the event West Fraser shall at any time after the Record Time and prior to the Separation Time issue any Common Shares otherwise than in a transaction referred to in this Section 2.3(a), each such Common Share so issued shall automatically have one new Right associated with it, which Right shall be evidenced by the certificate representing such associated Common Share.

(b) In the event West Fraser shall at any time after the Record Time and prior to the Separation Time fix a record date for the issuance of rights, options or warrants to all holders of Common Shares entitling them (for a period expiring within 45 calendar days after such record date) to subscribe for or purchase Common Shares (or securities convertible into or exchangeable for or carrying a right to purchase Common Shares) at a price per Common Share (or, if a security convertible into or exchangeable for or carrying a right to purchase or subscribe for Common Shares, having a conversion, exchange or exercise price, including the price required to be paid to purchase such convertible or exchangeable security or right per share) less than the Market Price per Common Share on such record date, the Exercise Price to be in effect after such record date shall be determined by multiplying the Exercise Price in effect immediately prior to such record date by a fraction:

(i) the numerator of which shall be the number of Common Shares outstanding on such record date, plus the number of Common Shares that the aggregate offering price of the total number of Common Shares so to be offered (and/or the

- 23 -

aggregate initial conversion, exchange or exercise price of the convertible or exchangeable securities or rights so to be offered, including the price required to be paid to purchase such convertible or exchangeable securities or rights) would purchase at such Market Price per Common Share; and

(ii) the denominator of which shall be the number of Common Shares outstanding on such record date, plus the number of additional Common Shares to be offered for subscription or purchase (or into which the convertible or exchangeable securities or rights so to be offered are initially convertible, exchangeable or exercisable).

In case such subscription price may be paid by delivery of consideration, part or all of which may be in a form other than cash, the value of such consideration shall be as determined in good faith by the Board of Directors, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of Rights. Such adjustment shall be made successively whenever such a record date is fixed, and in the event that such rights, options or warrants are not so issued, or if issued, are not exercised prior to the expiration thereof, the Exercise Price shall be readjusted to the Exercise Price which would then be in effect if such record date had not been fixed, or to the Exercise Price which would be in effect based upon the number of Common Shares (or securities convertible into, or exchangeable or exercisable for Common Shares) actually issued upon the exercise of such rights, options or warrants, as the case may be.

For purposes of this Agreement, the granting of the right to purchase Common Shares (whether from treasury or otherwise) pursuant to a Dividend Reinvestment Plan or any employee or director benefit, stock option, employee purchase, director compensation or similar plans shall be deemed not to constitute an issue of rights, options or warrants by West Fraser; provided, however, that, in all such cases, the right to purchase Common Shares is at a price per share of not less than 90% of the current market price per share (determined as provided in such plans) of the Common Shares.

(c) In the event West Fraser shall at any time after the Record Time and prior to the Separation Time fix a record date for the making of a distribution to all holders of Common Shares (including any such distribution made in connection with a merger, amalgamation, arrangement, plan, compromise or reorganization in which the Corporation is the continuing or successor Corporation) of evidences of indebtedness, cash (other than an Annual Cash Dividend or a dividend referred to in Section 2.3(a)(i), but including any dividend payable in securities other than Common Shares), assets or rights, options or warrants (excluding those referred to in Section 2.3(b) hereof), the Exercise Price to be in effect after such record date shall be determined by multiplying the Exercise Price in effect immediately prior to such record date by a fraction:

(i) the numerator of which shall be the Market Price per Common Share on such record date, less the fair market value (as determined in good faith by the Board of Directors, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of Rights), on a per share basis, of the portion of the cash, assets, evidences of indebtedness, rights, options or warrants so to be distributed; and

(ii) the denominator of which shall be such Market Price per Common Share.

- 24 -

Such adjustments shall be made successively whenever such a record date is fixed, and in the event that such a distribution is not so made, the Exercise Price shall be adjusted to be the Exercise Price which would have been in effect if such record date had not been fixed.

(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 1% in the Exercise Price; provided, however, that any adjustments which by reason of this Section 2.3(d) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under Section 2.3 shall be made to the nearest cent or to the nearest ten-thousandth of a share. Notwithstanding the first sentence of this Section 2.3(d), any adjustment required by Section 2.3 shall be made no later than the earlier of:

(i) (i)         three years from the date of the transaction which gives rise to such adjustment; or

(ii) the Expiration Time.

(e) In the event West Fraser shall at any time after the Record Time and prior to the Separation Time issue any shares of capital stock (other than Common Shares), or rights, options or warrants to subscribe for or purchase any such capital stock, or securities convertible into or exchangeable for any such capital stock in a transaction referred to in Sections 2.3(a)(i) or (iv) above, if the Board of Directors acting in good faith determines that the adjustments contemplated by Sections 2.3(a), (b) and (c) above in connection with such transaction will not appropriately protect the interests of the holders of Rights, the Board of Directors may determine what other adjustments to the Exercise Price, number of Rights and/or securities purchasable upon exercise of Rights would be appropriate and, notwithstanding Sections 2.3(a), (b) and (c) above, such adjustments, rather than the adjustments contemplated by Sections 2.3(a), (b) and (c) above, shall be made, subject to the prior consent of the holders of the Voting Shares or the Rights as set forth in Section 5.4(b) or (c), and West Fraser and the Rights Agent shall have authority upon receiving such prior consent of the holders of the Voting Shares to amend this Agreement as appropriate to provide for such adjustments.

(f) Each Right originally issued by West Fraser subsequent to any adjustment made to the Exercise Price hereunder shall evidence the right to purchase, at the Adjusted Exercise Price, the number of Common Shares purchasable from time to time hereunder upon exercise of a Right immediately prior to such issue, all subject to further adjustment as provided for herein.

(g) 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.

(h) 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, West Fraser 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 West Fraser, if

- 25 -

any, issuable upon such exercise over and above the number of Common Shares and other securities of West Fraser, if any, issuable upon such exercise on the basis of the Exercise Price in effect prior to such adjustment; provided, however, that West Fraser 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.

(i) Notwithstanding anything contained in this Section 2.3 to the contrary, West Fraser 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, with the intent that any:

(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 referred to in this Section 2.3,

hereafter made by West Fraser to holders of its Common Shares, subject to applicable taxation laws, shall not be taxable to such shareholders or shall subject such shareholders to a lesser amount of tax.

(j) If, as a result of an adjustment made pursuant to Section 3.1, the holder of any Right thereafter exercised shall become entitled to receive any securities other than Common Shares, thereafter the number of such other securities so receivable upon exercise of any Right and the applicable Exercise Price thereof shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as may be practicable to the provisions with respect to the Common Shares contained in the foregoing subsections of this Section 2.3 and the provisions of this Agreement with respect to the Common Shares shall apply on like terms to any such other securities.

(k) Whenever an adjustment to the Exercise Price or a change in the securities purchasable upon the exercise of Rights is made pursuant to this Section 2.3, West Fraser shall promptly:

(i) prepare a certificate setting forth such adjustment and a brief statement of the facts accounting for such adjustment;

(ii) file with the Rights Agent and with each transfer agent for the Common Shares a copy of such certificate; and

(iii) 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 any such adjustment or change.

- 26 -

2.4 Date on Which Exercise Is Effective

Each Person in whose name a registration in Book Entry Form for Common Shares or other securities, if applicable, is made 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 registration shall be dated the date upon which the Rights Certificate evidencing such Rights was duly surrendered in accordance with Section 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 West Fraser 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 West Fraser are open.

2.5 Execution, Authentication, Delivery and Dating of Rights Certificates

Rights will be evidenced, in the case of Rights in Book Entry Form, by a statement issued under the Rights Agent’s direct registration system, or alternatively, if West Fraser determines to issue Rights Certificates, by the following procedures:

(a) The Rights Certificates shall be executed on behalf of West Fraser by any two directors or officers of West Fraser. The signature of any of these directors or officers on the Rights Certificates may be manual or mechanically or electronically reproduced. Rights Certificates bearing the manual or mechanically or electronically reproduced signatures of individuals who were at any time the proper officers or directors of West Fraser shall bind West Fraser, 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 West Fraser learns of the Separation Time, West Fraser will notify the Rights Agent in writing of such Separation Time and will deliver the Rights Certificates executed by West Fraser to the Rights Agent for countersignature, as well as the disclosure statements describing the Rights, and the Rights Agent shall countersign (in a manner satisfactory to West Fraser) and send such Rights Certificates and disclosure statements to the holders of the Rights pursuant to Section 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.

2.6 Registration, Transfer and Exchange

(a) West Fraser will cause to be kept a register (the “Rights Register”) in which, subject to such reasonable regulations as it may prescribe, West Fraser 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 West Fraser 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.

- 27 -

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 Section 2.6(c), West Fraser will execute, and the Rights Agent will 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. Alternatively, in the case of the exercise of Rights in Book Entry Form, the Rights Agent shall provide the holder or the designated transferee or the transferees with one or more statements issued under the Rights Agent’s direct registration system evidencing the same aggregate number of Rights as did the direct registration system’s records for the Rights transferred or exchanged.

(b) All Rights issued upon any registration of transfer or exchange of Rights Certificates shall be the valid obligations of West Fraser, 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 West Fraser 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, West Fraser 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.

(d) West Fraser shall not be required to register the transfer or exchange of any Rights after the Rights have been terminated pursuant to the provisions of this Agreement.

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, West Fraser 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 West Fraser 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 them to save each of them and any of their agents harmless,

then, in the absence of notice to West Fraser or the Rights Agent that such Rights Certificate has been acquired by a bona fide purchaser, West Fraser shall execute and upon West Fraser’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.

- 28 -

(c) As a condition to the issuance of any new Rights Certificate under this Section 2.7, West Fraser 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.

(d) Every new Rights Certificate issued pursuant to this Section 2.7 in lieu of any destroyed, lost or stolen Rights Certificate shall evidence the contractual obligation of West Fraser, 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

West Fraser, the Rights Agent and any agent of West Fraser 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. As used in this Agreement, unless the context otherwise requires, the term “holder” of any Rights shall mean the registered holder of such Rights (or, prior to the Separation Time, of 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. West Fraser may at any time deliver to the Rights Agent for cancellation any Rights Certificates previously countersigned and delivered hereunder which West Fraser 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 West Fraser on request.

2.10 Agreement of Rights Holders

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

(a) to 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) that 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) that after the Separation Time, the Rights Certificates will be transferable only on the Rights Register as provided herein;

(d) that prior to due presentment of a Rights Certificate (or, prior to the Separation Time, the associated Common Share certificate, or if no certificate evidences the Common Share registration, satisfactory evidence of the associated Common Share registration) for registration of transfer, West Fraser, the Rights Agent and any agent of West Fraser or

- 29 -

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, or if no certificate evidences the Common Share registration, satisfactory evidence of the associated Common Share registration) 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 West Fraser or the Rights Agent) for all purposes whatsoever, and neither West Fraser nor the Rights Agent shall be affected by any notice to the contrary;

(e) that 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);

(f) that without the approval of any holder of Rights or Voting Shares and upon the sole authority of the Board of Directors acting in good faith, this Agreement may be supplemented or amended from time to time pursuant to Section 5.4(a) and the last sentence of the penultimate paragraph of Section 2.3(a); and

(g) that notwithstanding anything in this Agreement to the contrary, neither West Fraser nor the Rights Agent shall have any liability to any holder of a Right or to 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 government, 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 West Fraser 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 West Fraser or any right to vote at any meeting of shareholders of West Fraser whether for the election of directors or otherwise or upon any matter submitted to holders of Common Shares or any other shares of West Fraser at any meeting thereof, or to give or withhold consent to any action of West Fraser, or to receive notice of any meeting or other action affecting any holder of Common Shares or any other shares of West Fraser 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.

ARTICLE 3

ADJUSTMENTS TO THE RIGHTS IN THE EVENT OF CERTAIN TRANSACTIONS

3.1 Flip-in Event

(a) Subject to Section 3.1(b) and Section 5.1, in the event that prior to the Expiration Time a Flip-in Event shall occur, then:

(i) each Right shall constitute, effective at the close of business on the tenth Trading Day (or such longer period as may be required to satisfy the requirements of the

- 30 -

Securities Act and any comparable legislation of any other applicable jurisdiction) after the Stock Acquisition Date, the right to purchase from West Fraser, upon exercise of the Right in accordance with the terms of this Agreement, 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 the consummation or occurrence or event, an event of a type analogous to any of the events described in Section 2.3 shall have occurred);

(ii) in the event that there are insufficient authorized but unissued Common Shares to permit each holder of a Right (other than an Acquiring Person or a transferee of the kind described in Section 3.1(b)(ii)) to purchase from West Fraser that number of Common Shares per Right provided for in Section 3.1(a), then until such time as holders of Common Shares approve an increase in West Fraser’s authorized capital such that there are sufficient authorized but unissued Common Shares to permit each holder of a Right (other than an Acquiring Person or a transferee of the kind described in Section 3.1(b)(ii)) to purchase from West Fraser that number of Common Shares per Right provided for in Section 3.1(a), each whole Right shall constitute, effective at the close of business on the tenth Trading Day after the Stock Acquisition Date, the right to purchase from West Fraser, upon exercise thereof in accordance with the terms hereof, that number of Common Shares that is equal to one Common Share multiplied by the Adjustment Factor for an amount in cash equal to the Adjusted 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 the consummation or occurrence or event, 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 or other successor in title 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 or successor in title becomes a transferee or successor in title concurrently with or subsequent to the Acquiring Person becoming such in a transfer that the Board of Directors acting in good faith has determined is part of a plan, arrangement 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 Associate or Affiliate of an Acquiring Person), that has the purpose or effect of avoiding Section 3.1(b)(i),

- 31 -

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. The holder of any Rights represented by a Rights Certificate which is submitted to the Rights Agent upon exercise or for registration of transfer or exchange which does not contain the necessary certifications set forth in the Rights Certificate establishing that such Rights are not void under this subsection 3.1(b) shall be deemed to be an Acquiring Person for the purposes of this subsection 3.1(b) and such Rights shall be deemed and become null and void.

(c) From and after the Separation Time, West Fraser shall do all such acts and things as shall be necessary and within its power to ensure compliance with the provisions of Section 3.1, including without limitation, all such acts and things as may be required to satisfy the requirements of the BCBCA, the Securities Act (British Columbia), the Securities Act (Ontario), the U.S. Securities Act, the U.S. Exchange Act and the securities laws or comparable legislation in each of the provinces of Canada and each of the States of the United States in respect of the issue of Common Shares upon the exercise of Rights in accordance with this Agreement.

(d) Any Rights Certificate that would represent Rights Beneficially owned by a Person described in either Section 3.1(b)(i) or (ii) or transferred to any nominee of any such Person, and any Rights Certificate that would be issued upon transfer, exchange, replacement or adjustment of any other Rights Certificate referred to in this sentence, shall either not be issued upon the instruction of West Fraser in writing to the Rights Agent or contain the following legend:

The Rights represented by this Rights Certificate were issued to a Person who was an Acquiring Person or an Affiliate or an Associate of an Acquiring Person (as such terms are defined in the Shareholder Rights Plan Agreement) or a Person who was acting jointly or in concert with an Acquiring Person or an Affiliate or Associate of an Acquiring Person (as such terms are defined in the Shareholder Rights Plan Agreement). This Rights Certificate and the Rights represented hereby are void or shall become void in the circumstances specified in Section 3.1(b) of the Shareholder Rights Plan Agreement.

provided, however, that the Rights Agent shall not be under any responsibility to ascertain the existence of facts that would require the imposition of such legend but shall impose such legend only if instructed to do so by West Fraser in writing or if a holder fails to certify upon transfer or exchange in the space provided on the Rights Certificate that such holder is not a Person described in such legend. The issuance of a Rights Certificate without the legend referred to in this Section 3.1(d) shall be of no effect on the provisions of Section 3.1(b).

Any Rights issued and registered in Book Entry Form (that are evidenced by an advice or other statement on which are maintained electronically the records of the transfers) after the Separation Time but prior to the Expiration Time, shall evidence one Right for each Right represented by such registration and the registration record of such Rights

- 32 -

shall include the legend set forth in this Section 3.1(d), adapted accordingly as the Rights Agent may reasonably require.

ARTICLE 4

THE RIGHTS AGENT

4.1 General

(a) West Fraser hereby appoints the Rights Agent to act as agent for West Fraser and the holders of the Rights in accordance with the terms and conditions of this Agreement, and the Rights Agent hereby accepts such appointment. West Fraser may from time to time appoint one or more co-Rights Agents (“Co-Rights Agents”) as it may deem necessary or desirable, subject to the approval of the Rights Agent, acting reasonably. In the event West Fraser appoints one or more Co-Rights Agents, the respective duties of the Rights Agent and Co-Rights Agents shall be as West Fraser may determine with the approval of the Rights Agent and the Co-Rights Agents.

(b) West Fraser agrees to pay the Rights Agent reasonable compensation for all services rendered by it hereunder or otherwise agreed to with West Fraser in writing and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and other disbursements reasonably incurred in the execution and administration of this Agreement and the exercise and performance of its duties thereunder (including the reasonable fees and other disbursements of any expert retained by the Rights Agent with the approval of West Fraser, such approval not to be unreasonably withheld). West Fraser also agrees to indemnify the Rights Agent and its affiliates, and each of their officers, directors, employees and agents for, and to hold them harmless against, any loss, liability, cost, claim, action, damage or expense, incurred without negligence, bad faith or wilful misconduct on the part of the Rights Agent, its affiliates, or either of its officers, directors, employees, or agents for anything done or omitted by the Rights Agent in connection with the acceptance, execution and administration of this Agreement and the exercise and performance of its duties hereunder, including legal costs and expenses of defending against any claims or liability, which right to indemnification will survive the termination of this Agreement or the resignation or removal of the Rights Agent.

(c) The Rights Agent shall be protected from 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 West Fraser, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, opinion, 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.

(d) West Fraser 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 directors and officers of West Fraser; provided that failure to inform the Rights Agent of any such events, or any defect therein, shall not affect the validity of any action taken hereunder in relation to such events.

- 33 -

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

(a) Any company into which the Rights Agent or any successor Rights Agent may be merged or amalgamated or with which it may be consolidated, or any company resulting from any merger, amalgamation, statutory arrangement or consolidation to which the Rights Agent or any successor Rights Agent is a party, or any company succeeding to the securityholder 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 company 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 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 Certificates have not been countersigned, any successor Rights Agent may countersign such Rights Certificates in the name of either 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 Right 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 Right Certificates shall have the full force provided in the Right Certificates and in this Agreement.

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 West Fraser and the holders of certificates for Common Shares and Rights Certificates, by their acceptance thereof, shall be bound.

(a) The Rights Agent, at the expense of West Fraser, may retain and consult with legal counsel (who may be legal counsel for West Fraser and, in any event, shall be a reputable legal firm) 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 and the Rights Agent may also 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 (at West Fraser’s expense) and the Rights Agent shall be entitled to act and rely in good faith on the advice of any such expert.

(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 West Fraser 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 two Persons believed by the Rights Agent to be directors or officers of West Fraser and delivered to the Rights Agent; and such certificate will be full authorization to the Rights Agent for any action

- 34 -

taken or suffered in good faith by it under the provisions of this Agreement in reliance upon such certificate.

(c) The Rights Agent will be liable hereunder only for events which are the result of its own negligence, bad faith or wilful misconduct and that of its officers, directors and employees.

(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 (except as such are made or provided by the Rights Agent) 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 West Fraser 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 West Fraser 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 Section 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.

(f) Each of West Fraser and the Rights Agent 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 of the provisions of this Agreement.

(g) The Rights Agent is hereby authorized and directed to accept instructions in writing (including by e-mail) with respect to the performance of its duties hereunder from any individual believed by the Rights Agent to be any two officers or directors of West Fraser, 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. It is understood that instructions to the Rights Agent shall, except where circumstances make it impractical or the Rights Agent otherwise agrees, be given in writing (including by e-mail) and, where not in writing, such instructions shall be confirmed in writing (including by e-mail) as soon as practicable after the giving of such instructions.

(h) The Rights Agent and any shareholder or stockholder, director, officer or employee of the Rights Agent may buy, sell or deal in Common Shares, Rights or other securities of West Fraser or become financially interested in any transaction in which West Fraser may be interested, or contract with or lend money to West Fraser or otherwise act as fully and

- 35 -

freely as though it were not the Rights Agent under this Agreement. Nothing herein shall preclude the Rights Agent from acting in any other capacity for West Fraser or for any other legal entity, provided such actions would not place the Rights Agent in a position of conflict of interest with respect to its duties under this Agreement.

(i) 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, omission, default, neglect or misconduct of any such attorneys or agents or for any loss to West Fraser resulting from any such act, omission, default, neglect or misconduct, provided reasonable care was exercised in the selection and continued employment thereof.

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 West Fraser) in writing mailed to West Fraser and to each transfer agent of Common Shares by registered or certified mail. West Fraser 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, West Fraser will appoint a successor to the Rights Agent. If West Fraser fails to make such appointment within a period of 60 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 West Fraser the resigning or incapacitated Rights Agent (at West Fraser’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 West Fraser), may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by West Fraser or by such a court, shall be a company constituted under the laws of Canada or a province thereof authorized to carry on the business of a trust company in the Province of British Columbia. 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, upon the receipt of all outstanding fees and expenses, shall 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, West Fraser 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 5.9. The cost of giving any notice required under this Section 4.4 shall be borne solely by West Fraser. 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.

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 sanctions legislation or regulation or 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 sanctions legislation or regulation or 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 West Fraser, provided: (i) that the Rights Agent’s written notice shall describe the circumstances of such non-compliance to the extent permitted by any sanctions legislation or regulation or applicable anti-money

- 36 -

laundering or anti-terrorist legislation, regulation or guideline; 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. Subject to applicable law, the Rights Agent agrees to notify the Corporation as soon as reasonably possible in the event that the Rights Agent has a reasonable belief that circumstances exist which may give rise to the Rights Agent exercising its right to resign under this paragraph, and such notice shall describe the basis of such reasonable belief.

4.6 Privacy Legislation

The parties acknowledge that Privacy Laws may apply 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. West Fraser will, prior to transferring or causing to be transferred personal information to the Rights Agent pursuant to this Agreement, 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.

4.7 Liability

Notwithstanding any other provision of this Agreement, and whether such losses or damages are foreseeable or unforeseeable, the Rights Agent shall not be liable under any circumstances whatsoever for any (a) breach by any other party of securities law or other rule of any securities regulatory authority, (b) lost profits or (c) special, indirect, incidental, consequential, exemplary, aggravated or punitive losses or damages. This Section 4.7 shall survive the termination of this Agreement or the resignation or removal of the Rights Agent.

ARTICLE 5

MISCELLANEOUS

5.1 Redemption and Waiver

(a) The Board of Directors shall waive the application of Section 3.1 in respect of the occurrence of any Flip-in Event if the Board of Directors has determined, following a Stock Acquisition Date and prior to the Separation Time, that a Person became an Acquiring Person by inadvertence and without any intention to become, or knowledge that it would become, an Acquiring Person under this Agreement and, in the event that such a waiver is granted by the Board of Directors, such Stock Acquisition Date shall be deemed not to have occurred. Any such waiver pursuant to this Section 5.1(a) must be on the condition that such Person, within 14 days after the foregoing determination by the Board of Directors or such earlier or later date as the Board of Directors may determine (the “Disposition Date”), has reduced its Beneficial ownership of Voting Shares such that the Person is no longer an Acquiring Person. If the Person remains an Acquiring Person at the close of business on the Disposition Date, the Disposition Date shall be deemed to be the date of occurrence of a further Stock Acquisition Date and Section 3.1 shall apply thereto.

(b) The Board of Directors acting in good faith may, prior to a Flip-in Event having occurred, upon prior written notice delivered to the Rights Agent, determine to waive the application of Section 3.1 to a Flip-in Event that may occur by reason of a Take-over Bid made by means of a take-over bid circular to all holders of record of Voting Shares (which

- 37 -

for greater certainty shall not include the circumstances described in Section 5.1(a)), provided that if the Board of Directors waives the application of Section 3.1 to a particular Flip-in Event pursuant to this Section 5.1(b), 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 Take-over Bid which 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 (as the same may be extended from time to time) in respect of which a waiver is, or is deemed to have been granted under this Section 5.1(b).

(c) In the event that prior to the occurrence of a Flip-in Event a Person acquires, pursuant to a Permitted Bid, a Competing Permitted Bid or an Exempt Acquisition under Section 5.1(b), outstanding Voting Shares, then the Board of Directors shall, immediately upon the consummation of such acquisition without further formality be deemed to have elected to redeem the 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”).

(d) The Board of Directors may, with the prior approval of the holders of Voting Shares or Rights given in accordance with the terms of Section 5.4, at any time prior to the occurrence of a Flip-in Event elect to redeem all but not less than all of the then outstanding Rights at the Redemption Price appropriately adjusted in a manner analogous to the applicable adjustments provided for in Section 2.3, which adjustments shall only be made in the event that an event of the type analogous to any of the events described in Section 2.3 shall have occurred.

(e) The Board of Directors may, with the prior approval of the holders of Common Shares given in accordance with Section 5.4 at any time prior to the occurrence of a Flip-in Event as to which the application of Section 3.1 hereof has not been waived pursuant to Section 5.1(a), if such Flip-in Event would occur by reason of an acquisition of Common Shares or Convertible Securities otherwise than pursuant to a Take-over Bid made by means of a Take-over Bid circular to all registered holders of Common Shares and otherwise than in the circumstances set forth in Section 5.1(a), waive the application of Section 3.1 to such Flip-in Event. In such event, the Board of Directors shall extend the Separation Time to a date at least ten (10) Business Days subsequent to the meeting of shareholders called to approve such waiver.

(f) The Board of Directors may, prior to the close of business on the tenth Trading Day following a Stock Acquisition Date or such later Business Day as they may from time to time determine, upon prior written notice delivered to the Rights Agent, waive the application of Section 3.1 to the related Flip-in Event, provided that the Acquiring Person has reduced its Beneficial ownership of Voting Shares (or has entered into a contractual arrangement with West Fraser, acceptable to the Board of Directors, to do so within 10 calendar days of the date on which such contractual arrangement is entered into or such other date as the Board of Directors may have determined) such that at the time the waiver becomes effective pursuant to this Section 5.1(f) such Person is no longer an Acquiring Person. In the event of such a waiver becoming effective prior to the Separation Time, for the purposes of this Agreement, such Flip-in Event shall be deemed not to have occurred.

- 38 -

(g) Where a Take-over Bid that is not a Permitted Bid or a Competing Permitted Bid 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 the outstanding Rights at the Redemption Price. Notwithstanding the foregoing, upon the Rights being redeemed pursuant to this Section 5.1(g), all the provisions of this Agreement shall continue to apply as if the Separation Time had not occurred and Rights Certificates representing the number of Rights held by each holder of record of Common Shares as of the Separation Time had not been mailed to each such holder and for all purposes of this Agreement the Separation Time shall be deemed not to have occurred and the Rights shall remain attached to outstanding Common Shares subject to and in accordance with this agreement.

(h) If the Board of Directors is deemed under Section 5.1(c) to have elected or elects under Sections 5.1(d) or (g) to redeem the Rights, 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.

(i) Within 10 calendar days after the Board of Directors is deemed under Section 5.1(c) to have elected or elects under Section 5.1(d) or (g) to redeem the Rights, West Fraser 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 registry books of the Rights Agent or, prior to the Separation Time, on the registry books of the transfer agent for the Voting Shares. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of redemption will state the method by which the payment of the Redemption Price will be made.

(j) West Fraser shall give prompt written notice to the Rights Agent of any waiver of the application of Section 3.1 pursuant to this Section 5.1.

5.2 Expiration

No Person shall have any rights whatsoever pursuant to this Agreement or in respect of any Right after the Expiration Time, except the Rights Agent as specified in Section 4.1(a) of this Agreement.

5.3 Issuance of New Rights Certificates

Notwithstanding any of the provisions of this Agreement or of the Rights to the contrary, West Fraser may, at its option, issue new Rights Certificates evidencing Rights in such form as may be approved by the Board of Directors to reflect any adjustment or change in the number or kind or class of securities purchasable upon exercise of Rights made in accordance with the provisions of this Agreement.

5.4 Supplements and Amendments

(a) West Fraser may, prior to the date of the shareholders’ meeting referred to in the first paragraph of Section 5.15 supplement, amend, vary, rescind or delete any of the provisions of this Agreement and the Rights without the approval of any holders of Rights or Voting Shares in order to make any changes which the Board of Directors acting in good faith may deem necessary or desirable. West Fraser may make any amendments to this Agreement to correct any clerical or typographical error or which, subject to Section 5.4(f), are required to maintain the validity of the Agreement as a result of any change in

- 39 -

any applicable legislation, regulations or rules thereunder. Notwithstanding anything in this Section 5.4 to the contrary, no amendment shall be made to the provisions of Article 4 except with the written concurrence of the Rights Agent to such supplement or amendment.

(b) Subject to Section 5.4(a), West Fraser may, with the prior consent of the holders of Voting Shares obtained as set forth below, at any time before the Separation Time, amend, vary or rescind any of the provisions of this Agreement and the Rights (whether or not such action would materially adversely affect the interests of the holders of Rights generally), provided that no such amendment, variation or deletion shall be made to the provisions of Article 4 except with the written concurrence of the Rights Agent thereto. Such consent shall be deemed to have been given if provided by the holders of Voting Shares at a meeting of West Fraser shareholders called and held in compliance with applicable laws and regulatory requirements and the requirements in the notice of articles and the articles of West Fraser. Subject to compliance with any requirements imposed by the foregoing, consent shall be given if the proposed amendment, variation or rescission is approved by the affirmative vote of a majority of the votes cast by all holders of Voting Shares (other than any holder who does not qualify as an Independent Shareholder, with respect to all Voting Shares Beneficially owned by such Person), represented in person or by proxy at the shareholder meeting.

(c) West Fraser may, with the prior consent of the holders of Rights obtained as set forth below, at any time after the Separation Time and before the Expiration Time, amend, vary or rescind any of the provisions of this Agreement and the Rights (whether or not such action would materially adversely affect the interests of the holders of Rights generally), provided that no such amendment, variation or rescission shall be made to the provisions of Article 4 except with the written concurrence of the Rights Agent thereto. Such consent shall be deemed to have been given if provided by the holders of Rights at a Rights Holders’ Special Meeting, which Rights Holders’ Special Meeting shall be called and held in compliance with applicable laws and regulatory requirements and, to the extent possible, with the requirements in the notice of articles and the articles of West Fraser applicable to meetings of holders of Common Shares, applied mutatis mutandis. Subject to compliance with any requirements imposed by the foregoing, consent shall be given if the proposed amendment, variation or rescission is approved by the affirmative vote of a majority of the votes cast by holders of Rights (other than holders of Rights whose Rights have become null and void pursuant to Section 3.1(b)), represented in person or by proxy at the Rights Holders’ Special Meeting.

(d) Any consent or approval of the holders of Rights shall be deemed to have been given if the action requiring such approval is authorized by the affirmative votes of the holders of Rights present or represented at and entitled to be voted at a meeting of the holders of Rights and representing a majority of the votes cast in respect thereof. For the purposes hereof, each outstanding Right (other than Rights which are null and void pursuant to the provisions hereof) shall be entitled to one vote, and the procedures for the calling, holding and conduct of the meeting shall be those, as nearly as may be, which are provided in West Fraser’s notice of articles and articles and the BCBCA with respect to the meetings of holders of Common Shares.

(e) The Corporation shall be required to provide the Rights Agent with notice in writing of any such amendment, variation or deletion to this Agreement as referred to in this Section 5.4 within five days of effecting such amendment, variation or deletion.

- 40 -

(f) Any amendments, variations or deletions made by West Fraser to this Agreement pursuant to Section 5.4(a) which are required to maintain the validity of this Agreement as a result of any change in any applicable legislation, regulation or rule thereunder shall:

(i) if made before the Separation Time, be submitted to the holders of Voting Shares at the next meeting of shareholders and the holders of Voting Shares may, by the majority referred to in Section 5.4(b) confirm or reject such amendment;

(ii) if made after the Separation Time, be submitted to the holders of Rights at a meeting to be called for on a date not later than immediately following the next meeting of shareholders of West Fraser and the holders of Rights may, by resolution passed by the majority referred to in Section 5.4(d) confirm or reject such amendment.

Any such amendment shall be effective from the date of the resolution of the Board of Directors adopting such amendment, until it is confirmed or rejected or until it ceases to be effective (as described in the next sentence) and, where such amendment is confirmed, it continues in effect in the form so confirmed. If such amendment is rejected by the shareholders or the holders of Rights or is not submitted to the shareholders or holders of Rights as required, then such amendment shall cease to be effective from and after the termination of the meeting at which it was rejected or to which it should have been but was not submitted or from and after the date of the meeting of holders of Rights that should have been but was not held, and no subsequent resolution of the Board of Directors to amend this Agreement to substantially the same effect shall be effective until confirmed by the shareholders or holders of Rights as the case may be.

5.5 Fractional Rights and Fractional Shares

(a) West Fraser shall not be required to issue fractions of Rights or to distribute Rights Certificates which evidence fractional Rights and West Fraser shall not be required to pay any amount to a holder of record of Rights Certificates in lieu of such fractional Rights.

(b) West Fraser shall not be required to issue fractions of Common Shares upon exercise of Rights or to distribute certificates which evidence fractional Common Shares. In lieu of issuing fractional Common Shares, West Fraser shall be entitled to pay to the registered holders of Rights Certificates, at the time such Rights are exercised as herein provided, an amount in cash equal to the fraction of the Market Price of one Common Share that the fraction of a Common Share that would otherwise be issuable upon the exercise of such Right is of one whole Common Share at the date of such exercise.

5.6 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. Any holder of Rights, without the consent of the Rights Agent or of the holder of any other Rights, may, on such holder’s own behalf and for such holder’s own benefit and the benefit of other holders of Rights, enforce, and may institute and maintain any suit, action or proceeding against West Fraser to enforce such holder’s right to exercise such holder’s Rights, or Rights to which such holder is entitled, in the manner provided in such holder’s Rights Certificate and in this Agreement. Without limiting the foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holder of Rights would not have an adequate remedy at law for any breach of this Agreement and will be entitled to specific performance of

- 41 -

the obligations under, and injunctive relief against actual or threatened violations of the obligations of any Person subject to, this Agreement.

5.7 Regulatory Approvals

Any obligation of West Fraser 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, and without limiting the generality of the foregoing, necessary approvals of any stock exchange having been obtained be obtained, such as approvals relating to the issuance of Common Shares upon the exercise of Rights under Section 2.2(d).

5.8 Declaration as to Foreign 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 West Fraser 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 West Fraser 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 or the United States, in which such issue or delivery would be unlawful without registration of the relevant Persons or securities for such purposes.

5.9 Notices

(a) Notices or demands authorized or required by this Agreement to be given or made by the Rights Agent or by the holder of any Rights to or on West Fraser shall be sufficiently given or made if delivered, sent by registered or certified mail, postage prepaid (until another address is filed in writing with the Rights Agent), or sent by facsimile or other form of recorded electronic communication (including e-mail), charges prepaid and confirmed in writing, as follows:

UNDER CERTAIN CIRCUMSTANCES (SPECIFIED IN SECTION 3.1(b) OF THE SHAREHOLDER RIGHTS PLAN AGREEMENT), RIGHTS BENEFICIALLY OWNED BY AN ACQUIRING PERSON OR SUCH PERSON’S AFFILIATES OR ASSOCIATES (AS SUCH TERMS ARE DEFINED IN THE RIGHTS AGREEMENT) OR ANY PERSON ACTING JOINTLY OR IN CONCERT WITH THEM OR TRANSFEREES OF ANY OF THE FOREGOING WILL BECOME VOID WITHOUT FURTHER ACTION.

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 April 18, 2023, as the same may be amended or supplemented from time to time, (the “Shareholder Rights Plan Agreement”), between West Fraser Timber Co. Ltd., a company duly incorporated under the laws of British Columbia and Computershare Investor Services Inc., a company governed under the laws of Canada (the “Rights Agent”) (which term shall include any successor Rights Agent under the Shareholder Rights Plan Agreement), to purchase from West Fraser Timber Co. Ltd. at any time after the Separation Time (as such term is defined in the Shareholder Rights Plan Agreement) and prior to the Expiration Time (as such term is defined in the Shareholder Rights Plan Agreement), one fully paid common share of West Fraser Timber Co. Ltd. (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 Vancouver, British Columbia or any other cities as may be designated by West Fraser Timber Co. Ltd. from time to time. The Exercise Price shall be an amount equal to five times the Market Price (as defined in the Shareholder Rights Agreement) per Common Share determined as of the Separation Time per Right (payable in cash, certified cheque or money order payable to the order of the Corporation) and shall be subject to adjustment as provided in the Shareholder Rights Plan Agreement.

This Rights Certificate is subject to all of the terms and provisions of the Shareholder Rights Plan Agreement, which terms and provisions are incorporated herein by reference and made a part hereof and to which Shareholder Rights Plan Agreement reference is hereby made for a full description of the rights, limitations of rights, obligations, duties and immunities thereunder of the

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.

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 Plan Agreement or herein be construed to confer upon the holder hereof, as such, any of the Rights of a shareholder of West Fraser Timber Co. Ltd. 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 Plan 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 Plan Agreement.
