ANNUAL GENERAL MEETING OF SHAREHOLDERS

INFORMATION CIRCULAR

GENERAL INFORMATION

This Information Circular is furnished to the holders (“shareholders”) of common shares of the Company (“Common Shares”) by management of Ainsworth Lumber Co. Ltd. (the “Company”) in connection with the solicitation of proxies to be voted at the annual general meeting (the “Meeting”) of the shareholders to be held on Monday, May 5, 2008 and at any adjournment thereof, for the purposes set forth in the accompanying Notice of Meeting.

PROXIES

Solicitation of Proxies

The enclosed proxy is solicited by and on behalf of the management of the Company. The persons named in the enclosed proxy form are directors and senior officers of the Company. A registered shareholder desiring to appoint some other person (who need not be a shareholder) to represent the shareholder at the Meeting may do so either by inserting such other person’s name in the blank space provided in the proxy form or by completing another form of proxy. To be used at the Meeting, the completed proxy form must be deposited at the office of Computershare Investor Services Inc., Proxy Department, 100 University Avenue, 9th Floor, Toronto, Ontario M5J 2Y1 (Fax: 1-866-249-9524 (toll free within North America) or (416) 263-9524 (outside North America)) by mail or fax no later than 48 hours (excluding Saturdays, Sundays and holidays) prior to the time of the Meeting, or any adjournment thereof, or may be accepted by the chairman of the Meeting prior to the commencement of the Meeting. Solicitation will be primarily by mail, but some proxies may be solicited personally or by telephone by regular employees or directors of the Company at a nominal cost. The cost of solicitation by management of the Company will be borne by the Company.

Non-Registered Holders

Only registered holders of Common Shares or the persons they appoint as their proxyholders are permitted to vote at the Meeting. In many cases, however, Common Shares beneficially owned by a holder (a “Non-Registered Holder”) are registered either:

(a)		in the name of an Intermediary (an “Intermediary”) that the Non-Registered Holder deals with in respect of the shares. Intermediaries include banks, trust companies, securities dealers or brokers, and trustees or administrators of self-administered RRSPs, RRIFs, RESPs and similar plans, or

(b)		in the name of a clearing agency (such as The Canadian Depository for Securities Limited (CDS)) of which the Intermediary is a participant.

In accordance with the requirements of National Instrument 54-101 of the Canadian Securities Administrators, the Company has distributed copies of proxy-related materials in connection with this Meeting (including this Information Circular) to Intermediaries and clearing agencies for onward distribution to Non-Registered Holders.

Intermediaries are required to forward the proxy-related materials to Non-Registered Holders unless a Non-Registered Holder has waived the right to receive them. Intermediaries often use service companies to forward the proxy-related materials to Non-Registered Holders. Generally, Non-Registered Holders who have not waived the right to receive proxy-related materials will be sent a voting instruction form which must be completed, signed and returned by the Non-Registered Holder in accordance with the Intermediary’s directions on the voting instruction form. In some cases, such Non-Registered Holders will instead be given a proxy which has already been signed by the Intermediary (typically by a facsimile, stamped signature) which is restricted as to the number of Common Shares beneficially owned by the Non-Registered Holder but which is otherwise not completed. This form of proxy does not need to be signed by the Non-Registered Holder, but, to be used at the Meeting, needs to be properly completed and deposited with Computershare Investor Services Inc. as described under “Solicitation of Proxies”.

The purpose of these procedures is to permit Non-Registered Holders to direct the voting of the Common Shares that they beneficially own. Should a Non-Registered Holder wish to attend and vote at the Meeting in person (or have another person attend and vote on behalf of the Non-Registered Holder), the Non-Registered Holder should strike out the names of the persons named in the proxy and insert the Non-Registered Holder’s (or such other person’s) name in the blank space provided or, in the case of a voting instruction form, follow the corresponding instructions on the form.

Non-Registered Holders should carefully follow the instructions of their Intermediaries and their service companies, including instructions regarding when and where the voting instruction form or Proxy form is to be delivered.

Revocability of Proxies

A registered shareholder who has given a proxy may revoke it by a duly executed instrument in writing delivered either at the registered office of the Company at 19th Floor, 885 West Georgia Street, Vancouver, British Columbia V6C 3H4 at any time up to and including the last business day preceding the day of the Meeting, or any adjournment thereof at which the proxy is to be used, or to the chairman of the Meeting on the day of the Meeting or any adjournment thereof before any vote in respect of which the proxy is to be used shall have been taken, or in any other manner provided by law.

Voting of Proxies

A registered shareholder’s instructions on such shareholder’s proxy form as to the exercise of voting rights will be followed in casting such shareholder’s votes. In the absence of any instructions, the persons named by management as proxyholders in the enclosed proxy form will cast the shareholder’s votes in favour of the passage of the resolutions set forth herein and in the Notice of Meeting.

The enclosed proxy form confers discretionary authority upon the persons named therein with respect to (a) amendments or variations to matters identified in the Notice of Meeting and (b) other matters that may properly come before the Meeting or any adjournment thereof. At the time of printing of this Information Circular, management of the Company knows of no such amendments, variations or other matters to come before the Meeting other than the matters referred to in the Notice of Meeting.

VOTING SHARES AND PRINCIPAL HOLDERS THEREOF

Only the Common Shares without par value of the Company (“Common Shares”) carry voting rights at the Meeting with each Common Share carrying the right to one vote. The Board of Directors of the Company (the “Board of Directors” or “Board”) has fixed March 31, 2008 (the “Record Date”) as the record date for the determination of shareholders entitled to notice of and to vote at the Meeting and at any adjournment thereof, and only shareholders of record at the close of business on that date are entitled to such notice of and to vote at the Meeting. As of the Record Date, 14,649,140 Common Shares were issued and outstanding as fully paid and non-assessable. A complete list of the shareholders entitled to vote at the Meeting will be open to examination by any shareholder for any purpose germane to the Meeting, during ordinary business hours for a period of 10 days prior to the Meeting, at the office of Computershare Investor Services Inc. at 510 Burrard Street, Vancouver, British Columbia V6C 3B9.

To the knowledge of the directors or executive officers of the Company, persons or companies beneficially owning, or controlling or directing, directly or indirectly, Common Shares carrying more than 10% of the voting rights attached to the Company’s issued and outstanding Common Shares as at the Record Date, are as follows:


		Percentage of
Name	Number of Shares	Outstanding Shares
Grant Forest Products Corp.	5,001,160	34.1%
1234 Holdings Ltd.⁽¹⁾	3,108,188	21.2%
5678 Enterprises Ltd.⁽²⁾	2,757,186	18.8%
2468 Holdings Ltd.⁽³⁾	2,507,186	17.1%


(1)		96% of the outstanding voting shares of 1234 Holdings Ltd. are owned by David Ainsworth and the remainder is owned by Catherine Ainsworth. The Common Shares owned by 1234 Holdings Ltd. are voted by Catherine Ainsworth as that company’s representative in relation to proceedings of the Company’s shareholders. David Ainsworth also owns personally an additional 21,000 Common Shares and Catherine Ainsworth owns personally an additional 61,013 Common Shares.

(2)		All of the outstanding voting shares of 5678 Enterprises Ltd. are owned by D. Allen Ainsworth.

(3)		All of the outstanding voting shares of 2468 Holdings Ltd. are owned by Brian E. Ainsworth.

VOTES NECESSARY TO PASS RESOLUTIONS AT THE MEETING

Under the Company’s Articles, the quorum for transaction of business at the Meeting consists of two persons present and being, or representing by proxy, shareholders holding not less than one-twentieth of the Company’s issued Common Shares. Under the Company’s Articles and the Business Corporations Act (British Columbia), a simple majority of the votes cast at the Meeting (in person or by proxy) is required in order to pass the resolutions referred to in the accompanying Notice of Meeting.

APPOINTMENT OF AUDITOR

The persons named by management in the enclosed proxy form intend to vote for the appointment of Deloitte & Touche LLP, Chartered Accountants, as the auditor of the Company to hold office until the next annual general meeting of shareholders. Deloitte & Touche LLP has been the auditor of the Company or predecessor companies since the commencement of the financial year ended October 31, 1992.

ELECTION OF DIRECTORS

The number of directors of the Company is currently fixed at ten directors. As three incumbent directors will be retiring and not seeking re-election and there are three new director nominees, shareholders will be asked to again fix the number of directors at ten and to elect ten directors. The persons named below are the nominees of management for election as directors. Each director elected will hold office until the next annual general meeting or until his or her successor is elected or appointed, unless his or her office is earlier vacated under any of the relevant provisions of the Articles of the Company or the Business Corporations Act (British Columbia). It is the intention of the persons named by management as proxyholders in the enclosed proxy form to vote for the election to the Board of Directors of persons designated below as nominees for election as directors. The Board of Directors does not contemplate that any such nominees will be unable to serve as a director; however, if for any reason any of the proposed nominees does not stand for election or is unable to serve as such, proxies in favour of management designees will be voted for another nominee in their discretion unless the shareholder has specified in the shareholder’s proxy form that the shareholder’s shares are to be withheld from voting in the election of directors.

The following table sets out the name and place of residence of each of the persons proposed to be nominated for election as a director; all positions and offices in the Company presently held by him or her; his or her present principal occupation, business or employment (and, in the case of D. Michael Ainsworth, Douglas I. Ainsworth, and Kevin J. Ainsworth, who are nominated for election at a shareholders’ meeting of the Company for the first time, also their principal occupation and employment during the last five years); the period during which he or she has served as a director; and the number of Common Shares that he or she has advised are beneficially owned, or controlled or directed, directly or indirectly, by him or her as at the Record Date.

See “Employment Contracts and Termination Arrangements”.

(2)		The aggregate amount of perquisites and other personal benefits, securities or property paid to the Named Executive Officer did not exceed the lesser of $50,000 and 10% of the total annual cash compensation and bonus of the Named Executive Officer for the financial year.

(3)		Represents an automobile allowance and related expenses, a club membership and a golf course membership.

(4)		Represents personal use of corporate vehicles, life insurance premiums and other benefits.

Stock Options

The Company has an Employees’ Stock Option Plan (the “Employees’ Plan”) and a Directors’ Stock Option Plan (the “Directors’ Plan”) (collectively, the “Plans”) for employees (including executive officers) and non-employee directors, respectively. The Plans provide that the Board of Directors may grant options to purchase Common Shares on terms that the directors may determine, within the limitations of the Plans and subject to the rules of applicable regulatory authorities. The aggregate number of Common Shares reserved for issuance under each Plan is fixed at 500,000 Common Shares for the Employees’ Plan (which represents 3.4% of the currently issued and outstanding number of Common Shares) and 75,000 Common Shares for the Directors’ Plan (which represents 0.5% of the currently issued and outstanding number of Common Shares).

As at the date hereof, the total number of Common Shares (a) issued on the exercise of options granted under the Plans and (b) issuable under outstanding options granted under the Plans, and the respective percentages of the Company’s issued and outstanding Common Shares represented by such shares, were as follows:


	Common Shares Issued	Common Shares Issuable
	Upon Exercise of Options	Under Outstanding Options
Employees’ Plan	9,800 (0.1%)	Nil (0%)
Directors’ Plan	Nil (0%)	Nil (0%)

Accordingly, 490,200 Common Shares remain issuable pursuant to options that may be granted under the Employees’ Plan and all 75,000 Common Shares remain issuable pursuant to options that may be granted under the Directors’ Plan.

The Employees’ Plan and the Directors’ Plan contain the following provisions:

•		The exercise price for an option granted under the Plans will be determined by the Board of Directors but may not be less than the closing price of the Common Shares on the stock exchange on which the Common Shares principally traded on the day immediately preceding the date of grant;

•		The term of each option is five years;

•		The options are exercisable as to 20% of the optioned shares on the date of grant and as to a further 20% of the optioned shares on each of the first, second, third and fourth anniversaries following the date of grant;

•		An option is subject to earlier termination in the event the optionee ceases to be a director or employee of the Company by reason of death or termination of directorship or employment. In the case of the Employees’ Plan, if an optionee ceases to be an employee of the Company or any of its subsidiaries for any reason (other than death) or receives notice of termination of such employment, then any outstanding vested option held by the optionee would earlier terminate on the earlier of 30 days after cessation of employment and 30 days after any notice of termination of employment (with the mentioned 30-day periods being extendable for up to one year in the discretion of the Board of Directors), provided that if the optionee continues to be a director of the Company or any of its subsidiaries, the option would earlier terminate 30 days after the optionee ceases to be a director. In the case of the Directors’ Plan, if an optionee ceases to be a director of the Company for any reason (other than death), then any outstanding vested option held by the optionee would earlier terminate 30 days after the optionee ceases to be a director. In the event of death, options granted under either Plan would earlier terminate on such date specified in the optionee’s option agreement which may be up to one year after death;

•		Options granted under the Plans are not assignable, except by will or the laws of descent and distribution; and

•		The Board of Directors of the Company may make amendments to the Plans, subject to any necessary shareholder and regulatory approvals. Amendments to a Plan which would require such approvals include any amendment to the Plan which would materially increase the benefits under the Plan, materially increase the number Common Shares issuable under the Plan, or materially modify the requirements as to eligibility for participation in the Plan.

The Company does not provide any financial assistance to optionees in order to facilitate the purchase of Common Shares pursuant to the exercise of options granted under the Plans. The Plans do not contain any provisions for options to be transformed into stock appreciation rights.

During the financial year ended December 31, 2007, no stock options were granted to or exercised by the Named Executive Officers. As at December 31, 2007, the Named Executive Officers did not hold any outstanding stock options.

Employee Participation Share Plan

An aggregate of 1,500,000 Class B Common Shares are authorized for issuance under the Employee Participation Plan (the “EPSP”). The EPSP provides that the Board of Directors may permit designated directors and senior employees of the Company and its subsidiaries to acquire Class B Common Shares on the terms set forth in the EPSP. The Class B Common Shares may be issued in series under the EPSP and 1,500,000 Common Shares (which represents 10.2% of the currently issued and outstanding Common Shares) were originally reserved for issuance to provide for the conversion of the Class B Common Shares into Common Shares.

The EPSP provides that each series of Class B Common Shares will be exchanged automatically on a date fixed by the Board of Directors for that number of Common Shares of the Company which has value on the date of exchange equal to the amount of any increase in the value from the date fixed by resolution of the Board of Directors when authorizing the issuance of the Class B Common Shares of an equal number of Common Shares; if there is no such increase in value, then the number of Common Shares to be exchanged for Class B Common Shares on the date of exchange is equal to the number obtained by dividing the aggregate price paid for the Class B Common Shares by the fair market value of a Common Share on the date of exchange. In the event of termination of the employment and offices of a holder of Class B Common Shares, the date of exchange will be accelerated and the number of “vested” shares held is subject to reduction. Class B Common Shares issued pursuant to the EPSP may be redeemed by the Company at any time upon payment of the amount paid up and any declared but unpaid dividends.

As at the date hereof, the total number of Common Shares (a) issued on the exchange of Class B Common Shares granted under the EPSP and (b) issuable on the exchange of outstanding Class B Common Shares granted under the EPSP, and the respective percentages of the Company’s issued and outstanding Common Shares represented by such shares, were as follows:


Common Shares issued on exchange		Common Shares issuable on exchange of
of Class B Common Shares		outstanding Class B Common Shares
115,264 (0.8%)		Nil (0%)

During the financial year ended December 31, 2007, no Named Executive Officers were issued or held Class B Common Shares under the EPSP.

Pension Benefits

Retirement benefits for the executive officers of the Company are provided under the Company’s pension plan (the “Pension Plan”) for all salaried employees, except for D. Allen Ainsworth. The Pension Plan benefits are based on career average earnings, accrued at 1.5% of yearly maximum pensionable earnings (“YMPE”) plus 2% of gross earnings over YMPE. Benefits for all service accrued to December 31, 2007 are based on this same formula, but using average compensation over the previous five-year period and the YMPE over the previous three-year period. Compensation covered by the plan is the gross earnings as disclosed in the Summary Compensation Table. The benefits are computed on a guaranteed five-year life annuity, with no deduction for any other pension benefits received or other offset amounts.

Report on Executive Compensation

Composition of the Compensation Committee

A Compensation Committee of the Board of Directors (the “Committee”) oversees the Company’s compensation policies for executive officers as approved by the Board of Directors. The following directors (all of whom are independent directors within the meaning of NI 58-101) served as members of the Committee during the year ended December 31, 2007:

Douglas B. Buchanan

Robert A. Fairweather

K. Gordon Green

W. Gordon Lancaster

Policy of the Compensation Committee

Pursuant to its charter, the Committee has the responsibility of ensuring that the Company’s compensation practices and standards remain fully market competitive. The Company seeks to motivate performance by directly linking annual incentive compensation to the Company’s financial performance. Pursuant to its mandate, the Committee monitors and makes recommendations to the Board with respect to the total compensation (including direct salary and annual bonus as well as any long-term stock-related incentives and pension plans) paid to each executive officer, taking into consideration the Company’s financial performance and industry standards. It also reviews, as long as the Ainsworth family as a group controls at least 50% of the voting shares of the Company, the total compensation paid to any member of the Ainsworth family who is not an executive officer but whose aggregate annual compensation exceeds $100,000.

Elements of Executive Compensation

There are seven executive officers of the Company, six of whom are directly or indirectly major shareholders of the Company or directly related to such major shareholders (collectively, the “Shareholder Executives”). The Company’s principal means of compensating all executives is through cash compensation by way of base salaries and annual incentives. Long-term incentive plans such as stock options, special or “executive” pension plans and securities purchase programs are not considered appropriate given the current share ownership.

Historically, the six Shareholder Executives have elected to be compensated collectively in two tiers rather than individually. The first tier (“Tier 1”) includes the Chairman and Chief Executive Officer, the President, and the Chief Operating Officer. The base salary of each of these executives is established at a level competitive with his or her comparable position in industry. The second group (“Tier 2”) includes the Executive Vice-President, the Senior Vice-President, Marketing and the Senior Vice-President, Western Panel Operations. The base salary of each Tier 2 executive is identical with the base salary of each of the other two Tier 2 executives. The aggregate base salaries of the three Tier 2 positions are maintained at a level competitive with the aggregate base salaries of the comparable industry positions.

The Company has an executive bonus plan (the “Plan”) for the Shareholder Executives. The Plan is driven entirely by the Company’s financial performance. Under the Plan, budgeted earnings before income taxes, depreciation and amortization (“EBITDA”) as approved each year by the Board is designated as the target against which subsequent performance will be measured. The target aggregate bonus level for the Shareholder Executives is set annually to reflect industry conditions. The actual bonus paid in any year will vary with reported EBITDA as compared to budgeted EBITDA for the year, subject to a minimum and maximum payout and subject to a defined minimum amount of free cash flow.

In 2007, the Company reported negative EBITDA. In view of this and the persistent decline in industry conditions, no bonuses were paid to the Shareholder Executives for 2007.

In 2006, the Committee had retained the services of Mercer Human Resource Consulting (“Mercer”), an independent consulting firm, to assist it in determining the appropriate 2006 compensation levels of its seven executive officers, including each of the Shareholder Executives within the two tiers. Due to the absence of any bonus payments to the Shareholder Executives in 2006, Mercer indicated that while base salaries were in line with the market, aggregate total direct compensation fell materially below the median of the comparator group.

With respect to 2007, in light of the continued poor economic and financial conditions, the Committee concluded that there should be no overall increase to the previous year’s compensation levels, and that Mercer need not be retained, as it had been in past years, to opine on the suitability and appropriateness of the compensation package. Because the previous year’s total compensation fell materially below the comparator group, it was clear to the Committee that aggregate total direct compensation for 2007 was also materially below market.

Going forward, the Committee concluded that, under normalized economic conditions, total compensation paid to the Shareholder Executives beyond 2007 should be maintained at the median level or the 50th percentile of the comparator group.

CEO’s Compensation

The Chief Executive Officer’s compensation in fiscal 2007 was determined using the criteria described in the preceding section. In 2007, the Company paid Brian Ainsworth salary of $480,769 and paid a fee of $19,231 to 2468 Holdings Ltd. for services provided to the Company by Brian Ainsworth for a total base salary of $500,000 received by Brian Ainsworth directly or indirectly. No amount was paid to Brian Ainsworth or 2468 Holdings Ltd. in respect of any annual incentive bonus for 2007. Total direct and indirect compensation of $500,000 for the Chief Executive Officer’s services in 2007 is below the market as defined above.

This report is submitted on behalf of the Compensation Committee of the Board.
