(the “Corporation”, “Lorus”, “we” or “our”) to be held on Tuesday, November 29, 2011 at 10:00 a.m. (Toronto time) at the Hyatt Regency, 370 King Street West, Toronto, Ontario and at all adjournments thereof, for the purposes set forth in the accompanying notice of Meeting. It is expected that the solicitation will be made primarily by mail but proxies may also be solicited personally by directors, officers, employees or agents of the Corporation. The solicitation of proxies by this Circular is being made by or on behalf of the management of the Corporation. The total cost of the solicitation will be borne by Lorus. The information contained in this Circular is given as at October 28, 2011 except where otherwise noted.

CAUTION REGARDING FORWARD-LOOKING STATEMENTS

This Circular contains forward-looking statements within the meaning of securities laws, including without limitation, amount of payments required to Named Executive Officers(as such term is defined hereinafter) in the event of termination or a change in control. Such statements include, but are not limited to the Corporation’s plans, objectives, expectations and intentions and other statements including words such as “anticipate”, “contemplate”, “continue”, “believe”, “plan”, “estimate”, “expect”, “intend”, “will”, “should”, “may”, and other similar expressions.

Such statements reflect our current views with respect to future events and are subject to risks and uncertainties and are necessarily based upon a number of estimates and assumptions that, while considered reasonable by us are inherently subject to significant business, economic, competitive, political and social uncertainties and contingencies. Many factors could cause our actual results, performance or achievements to be materially different from any future results, performance, or achievements that may be expressed or implied by such forward-looking statement. See our Annual Information Form dated August 26, 2011 for the fiscal year ended May 31, 2011 for additional information. A copy of this document can be found on SEDAR at www.sedar.com.

ABOUT VOTING YOUR SHARES

Appointment of Proxies

This is the easiest way to vote. Voting by proxy means that you are giving the person or people named on your proxy form (the “proxyholder”) the authority to vote your Shares for you at the Meeting or any adjournment. A proxy form is included with this Circular.

The persons named on the proxy form will vote your Shares for you, unless you appoint someone else to be your proxyholder. You have the right to appoint a person or company to represent you at the Meeting other than the persons named on the proxy form. If you appoint someone else, he or she must be present at the Meeting to vote your Shares. If you want to appoint someone else, you can insert that person's name in the blank space provided in the form of proxy. That other person does not need to be a Shareholder of the Corporation.

If you are voting your Shares by proxy, our transfer agent, Computershare Investor Services Inc. (“Computershare”), must receive your completed proxy form by 10:00 a.m. (Toronto time) on Thursday, November 25, 2011 or, if the Meeting is adjourned, 48 hours (excluding Saturdays, Sundays and holidays) before any adjournment of the Meeting.

Registered Shareholders

You are a registered Shareholder if your name appears on your Share certificate. Your proxy form tells you whether you are a registered Shareholder.

Non-Registered (or Beneficial) Shareholders

You are a non-registered (or beneficial) Shareholder if your bank, trust company, securities broker or other financial institution holds your Shares for you (your nominee). For most of you, your voting instruction form or proxy tells you whether you are a non-registered (or beneficial) Shareholder.

In accordance with Canadian securities law, we have distributed copies of the notice of Meeting, this Circular and the form of proxy (collectively, the “meeting materials”) to CDS Clearing and Depository Services Inc. and intermediaries (such as securities brokers or financial institutions) for onward distribution to those non-registered or beneficial Shareholders to whom we have not sent the meeting materials directly. We previously mailed to those who requested them, the audited financial statements of the Corporation for the fiscal year ended May 31, 2011 and the auditors' report thereon as well as management's discussion and analysis.

The intermediaries are required to forward meeting materials to non-registered or beneficial Shareholders unless a non-registered or beneficial Shareholder has waived the right to receive them. Very often, intermediaries will use a service company such as Broadridge Investor Communication Solutions to forward the meeting materials to non-registered or beneficial Shareholders.

Non-registered or beneficial Shareholders who have not waived the right to receive meeting materials will receive either a voting instruction form or, less frequently, a form of proxy. The purpose of these forms is to permit non-registered or beneficial Shareholders to direct the voting of the Shares they beneficially own. Non-registered or beneficial Shareholders should follow the procedures set out below, depending on what type of form they receive.

Voting Instruction Form. In most cases, a non-registered Shareholder will receive, as part of the meeting materials, a voting instruction form. If the non-registered Shareholder does not wish to attend and vote at the Meeting in person (or have another person attend and vote on the non-registered Shareholder's behalf), the voting instruction form must be completed, signed and returned in accordance with the directions on the form. If a non-registered Shareholder wishes to attend and vote at the Meeting in person (or have another person attend and vote on the non-registered Shareholder's behalf), the non-registered Shareholder must complete, sign and return the voting instruction form in accordance with the directions provided and a form of proxy giving the right to attend and vote will be forwarded to the non-registered Shareholder.

Form of Proxy. Less frequently, a non-registered Shareholder will receive, as part of the meeting materials, a form of proxy that has already been signed by the intermediary (typically by a facsimile or stamped signature), which is restricted as to the number of Shares beneficially owned by the non-registered Shareholder but which is otherwise uncompleted. If the non-registered Shareholder does not wish to attend and vote at the Meeting in person (or have another person attend and vote on the non-registered Shareholder's behalf), the non-registered Shareholder must complete the form of proxy and deposit it with Computershare, 100 University Avenue, 8th Floor Toronto, Canada, M5J 2Y1 as described above. If a non-registered Shareholder wishes to attend and vote at the Meeting in person (or have another person attend and vote on the non-registered Shareholder's behalf), the non-registered Shareholder must strike out the names of the persons named in the proxy and insert the non-registered Shareholder's (or such other person's) name in the blank space provided.

Non-registered Shareholders should follow the instructions on the forms they receive and contact their intermediaries promptly if they need assistance.

Meeting Materials

The meeting materials are being sent to both registered and non-registered owners of Shares. If you are a non-registered owner, and the Corporation or its agent has sent the meeting materials directly to you, your name and address and information about your holdings of securities, have been obtained in accordance with applicable securities regulatory requirements from the intermediary holding on your behalf.

By choosing to send the meeting materials to you directly, the Corporation (and not the intermediary holding on your behalf) has assumed responsibility for (i) delivering the meeting materials to you, and (ii) executing your proper voting instructions. Please return your voting instructions as specified in the request for voting securities.

Changing Your Vote

A registered Shareholder who has given a proxy may revoke that proxy by:

(a)

completing and signing a proxy bearing a later date and depositing it with Computershare as described above;

(b)

depositing an instrument in writing executed by the Shareholder or by the Shareholder's attorney authorized in writing:

(i)

at our registered office at any time before 10:00 a.m. on Thursday, November 25, 2011, or 48 hours (not including Saturdays, Sundays and holidays) before any adjournment of the Meeting at which the proxy is to be used, or

(ii)

with the chair of the Meeting prior to the commencement of the Meeting on the day of the Meeting or any adjournment of the Meeting; or

(c)

in any other manner permitted by law.

A non-registered or beneficial Shareholder may revoke a voting instruction form or a waiver of the right to receive meeting materials and to vote given to an intermediary or to the Corporation, as the case may be, at any time by written notice to the intermediary or the Corporation, except that neither an intermediary nor the Corporation is required to act on a revocation of a voting instruction form or of a waiver of the right to receive materials and to vote that is not received by such intermediary or the Corporation, at least seven (7) days prior to the Meeting.

VOTING OF PROXIES

You can choose to vote “For”, “Against” or “Withhold”, depending on the items listed on the proxy form.

When you sign the proxy form, you authorize the management representatives named in the proxy form to vote your Shares for you at the Meeting according to your instructions.

If you return your proxy form and do not tell us how you want to vote your Shares, your Shares will be voted by the management representatives named in the proxy form as follows:

• FOR the election of the directors nominated for election as listed in this Circular;

• FOR the appointment of KPMG LLP as auditors of the Corporation;

•

FOR the approval of the unallocated options, rights and other entitlements under the security based compensation plans of the Corporation; and

•

FOR the approval of amendments to the terms of certain outstanding common share purchase warrants of the Corporation.

The enclosed form of proxy confers discretionary authority upon the management representatives designated in the form of proxy with respect to amendments to or variations of matters identified in the notice of Meeting and with respect to other matters that may properly come before the Meeting. At the date of this Circular, the management of the Corporation knows of no such amendments, variations or other matters.

VOTING SECURITIES AND PRINCIPAL HOLDERS OF VOTING SECURITIES

On October 28, 2011, 21,168,746 Shares are issued and outstanding. Each holder of Shares of record at the close of business on October 28, 2011, the record date established for notice of the Meeting, will be entitled to one vote for each Share held on all matters proposed to come before the Meeting, except to the extent that the Shareholder has transferred any Shares after the record date and the transferee of such Shares establishes ownership of them and makes a written demand, not later than 10 days prior to the Meeting, to be included in the list of Shareholders entitled to vote at the Meeting, in which case the transferee will be entitled to vote such Shares.

To the knowledge of Lorus' directors and executive officers, no single person or entity beneficially owns, directly or indirectly, or exercises control or direction over more than 10% of the votes attached to all the outstanding Shares, other than Mr. Herbert Abramson and his affiliated company Technifund Inc. who, according to information furnished to the Corporation, hold 9,436,041 Shares or approximately 44.58% of the Shares issued and outstanding.

PARTICULARS OF MATTERS TO BE ACTED UPON

1. Appointment and Remuneration of Auditors

Unless you have specified in the enclosed form of proxy that the votes attaching to the Shares represented by the proxy are to be withheld with respect to the appointment of auditors, on any ballot that may be called for in the appointment of auditors, the management representatives designated in the enclosed form of proxy intend to vote the Shares in respect of which they are appointed proxy FOR the appointment of KPMG LLP, Chartered Accountants, as auditors of the Corporation to hold office until the next annual meeting of Shareholders, and authorizing the directors to fix the remuneration of the auditors.

2. Election of Directors

Management does not contemplate that any of the proposed nominees will be unable to serve as a director but, if that should occur for any reason prior to the Meeting, the management representatives designated in the enclosed form of proxy may vote for another nominee at their discretion.

Pursuant to the articles of the Corporation, the number of directors of the Corporation is set at a minimum of three and a maximum of eleven and the directors are authorized to determine the actual number of directors to be elected from time to time.

3. Security Based Compensation Plan - Approval of Unallocated Options, Rights and Other Entitlements

The rules of the Toronto Stock Exchange (the “TSX”) require that, if a listed issuer has a stock option plan or other compensation plans that does not have a fixed maximum number of shares issuable thereunder, the directors and shareholders of the issuer must approve and reaffirm the unallocated options, rights or entitlements under the plan every three years.

At the annual and special shareholders’ meeting held on October 2, 2008 (the “2008 Annual Meeting”), the Shareholders approved the unallocated options. As the three-year term prescribed by the TSX expired on October 1, 2011, an ordinary resolution will be placed before the Shareholders to approve the unallocated options, rights and other entitlements under the security based compensation plans of the Corporation, being the stock option plan adopted in 1993 (the “1993 Plan”), the stock option plan adopted in 2003 (the “2003 Plan”) and the alternative compensation plan (the “ACP”). This approval will be effective for three years from the date of the Meeting. If approval is not obtained at the Meeting, options, rights and other entitlements which have not been allocated as of October 1, 2011 (i.e. the date that is 3 years after the prior approval, at the 2008 Annual Meeting) and options, rights and other entitlements which were outstanding as of October 1, 2011 and were subsequently cancelled, terminated or exercised will not be available for a new grant. Previously allocated options, rights and other entitlements will continue to be unaffected by the approval or disapproval of the resolution. As at October 28, 2011, 21,168,746 Shares are issued and outstanding and options to purchase an additional 1,169,541 Shares (5.5% of Shares outstanding) under the 1993 Plan and the 2003 Plan are outstanding and no shares have been issued under the ACP. Accordingly, as at that date, options, rights and other entitlements to purchase up to an additional 2,005,770 Shares (9.5% of Shares outstanding) remain available for grant under the 1993 Plan, the 2003 Plan and the ACP (the “Unallocated Options”).

The board of directors of the Corporation (the “Board”) has approved the Unallocated Options.

Additional information concerning the 1993 Plan, the 2003 Plan and the ACP, including their terms and conditions, can be found under the heading “Equity Compensation Plan Information” of this Circular.

At the Meeting, Shareholders will be asked to consider, and if deemed advisable, to approve and reaffirm the Unallocated Options. The text of the ordinary resolution which management of the Corporation intends to place before the Meeting for consideration and approval is set out below.

BE IT RESOLVED as an ordinary resolution of the Corporation that:

the unallocated options, rights and other entitlements under the security based compensation plans of the Corporation are approved and affirmed;

the Corporation seek further shareholder approval of unallocated options, rights and other entitlements under the security based compensation plans of the Corporation no later than November 28, 2014; and

any director or officer of the Corporation is hereby authorized and directed for and in the name of and on behalf of the Corporation to execute, or cause to be executed, whether under corporate seal of the Corporation or otherwise, and to deliver or cause to be delivered such certificates, instruments, agreements, notices and other documents, and to do or cause to be done all such other acts and things as such director or officer determines to be necessary or desirable in connection with the foregoing, such determination to be conclusively evidenced by the execution of such document, agreement or instrument or the doing of any such act or filing.

Unless otherwise instructed by a Shareholder, the persons named in the accompanying form of proxy will vote “FOR” the resolution approving the Unallocated Options.

4. Approval of Amendments to the Terms of Certain Warrants

At the Meeting, shareholders will be asked to consider and, if deemed appropriate, to pass, a resolution, in the form set out below approving an amendment to the terms of certain outstanding common share purchase warrants of the Corporation (the “November 2010 Warrants”) that were issued as part of the rights offering of the Corporation completed in November 2010 (the “November 2010 Rights Offering”), the details of which are described below. Each November 2010 Warrant entitles its holder to acquire one common share of the Corporation at a price of $1.33 per share until May 2012. The Corporation would like to amend the exercise price of the November 2010 Warrants from the $1.33 current exercise price to an exercise price equal to the 5-day volume weighted average trading price of the common shares of the Corporation on the TSX on the date of the approval of the Shareholders to such amendment at the Meeting, plus a 10% premium (to be rounded up). While the exact price of the warrants will be determined on November 29, if the warrants were repriced as at October 28, 2011, the five day VWAP would be $0.26, resulting in a revised warrant exercise price of $0.29.

Mr. Herbert Abramson, a director and major shareholder of the corporation who currently owns, directly or indirectly, 44.58% of the issued and outstanding common shares of the Corporation holds 3,600,259 November 2010 Warrants. Should Mr. Abramson exercise all of the November 2010 Warrants held by him, he would own approximately 52.6% of the issued and outstanding common shares of the Corporation on a partially diluted basis. Also Dr. Jim Wright who is a director of the Corporation holds 2,000 November 2010 Warrants, Dr. Aiping Young, a director and President and Chief Executive Officer of the Corporation, and Ms. Elizabeth Williams, Director of Finance and Acting Chief Financial Officer of the Corporation, hold 45,000 and 142, respectively, November 2010 Warrants.

The 2010 November Warrants have been issued as part of the November 2010 Rights Offering, a distribution by Lorus by way of short-form prospectus in each of the provinces of Canada to its shareholders in eligible jurisdictions outside the United States of rights exercisable for units of the Corporation. Under the November 2010 the Rights Offering, holders of common shares of the Corporation as of October 12, 2010, the record date, received one right for each common share held as of the record date. Each two rights entitled the holder thereof to purchase one unit of the Corporation at a price of $1.11 per unit. Each unit consisted of one common share of the Corporation and one November 2010 Warrant. A total of 4.2 million units of the Corporation at a price of $1.11 per unit were issued in connection with the November 2010 Rights Offering. As a result of the November 2010 Rights Offering, Lorus issued 4.2 million common shares and 4.2 million November 2010 Warrants for net proceeds of $4.2 million. In connection with the November 2010 Rights Offering, the Corporation secured a standby purchase arrangement of $4 million by Mr. Abramson. Mr. Abramson agreed to make an investment such that the minimum gross proceeds of the proposed November 2010 Rights Offering would be $4 million. No fee was payable to Mr. Abramson for this commitment. In accordance with the terms of the standby purchase agreement, Mr. Abramson subscribed for 3.6 million of the 4.2 million units of the November 2010 Rights Offering for $4.0 million.

The current exercise price of the November 2010 Warrants is $1.33 which is significantly above the current trading price of the Corporation’s common shares. It is the Corporation’s view that the likelihood that any of the November 2010 Warrants being exercised is unlikely at the current exercise price. Therefore, we believe amending the exercise price of the November 2010 Warrants would likely provide the Corporation with a further means of raising additional capital through the potential exercise of the November 2010 Warrants and thus saving the cost of doing an additional financing.

Pursuant to the requirements of the TSX the amendments to the November 2010 Warrants requires the approval of a majority of the votes cast by the shareholders of the Corporation, excluding insiders who are also warrantholders (the “Disinterested Shareholders”) at the Meeting. The Corporation has applied to the TSX for its approval to the proposed amendments.

The directors of the Corporation, other than Mr. Abramson, Dr. Wright and Dr. Young, who restrained from voting, have determined that the amendment to the exercise price of the November 2010 Warrants is in the best interests of the Corporation and is fair to the warrantholders and Shareholders. The directors of the Corporation recommend that Disinterested Shareholders vote in favour of the amendment to the exercise price of the November 2010 Warrants. To be effective, the resolution approving the amendment to the exercise price of the November 2010 Warrants must be approved by not less than a majority of the votes cast by the Disinterested Shareholders present in person, or represented by proxy, at the Meeting.

The text of the resolution approving the amendment to the exercise price of the November 2010 Warrants to be submitted to shareholders at the Meeting is set forth below:

BE IT RESOLVED THAT:

The Corporation is hereby authorized to amend the exercise price of the common share purchase warrants of the Corporation (the “November 2010 Warrants”) that were issued as part of the rights offering of the Corporation completed in November 2010 so that the exercise price be changed from $1.33 to an exercise price equal to the 5-day volume weighted average trading price of the common shares of the Corporation on the Toronto Stock Exchange on November 29, 2011, plus a 10% premium (to be rounded up).

Any director or officer of the Corporation is authorized and directed to execute and deliver for and in the name of and on behalf of the Corporation, under its corporate seal or otherwise, all such certificates, instruments, agreements, notices and other documents and to do such other acts and things as, in the opinion of such person, may be necessary or desirable in connection with the amendment to the exercise price of the November 2010 Warrants, with the performance of the Corporation of its obligations in connection therewith, and to give effect to the foregoing and facilitate the implementation of the foregoing resolution; and

Notwithstanding that this resolution has been passed by the shareholders of the Corporation, the directors of the Corporation are hereby authorized to revoke the resolution before it is acted on without further approval of the shareholders of the Corporation.

Unless otherwise instructed by a Shareholder, the persons named in the accompanying form of proxy will vote “FOR” the resolution approving the amendment to the exercise price of the November 2010 Warrants.

STATEMENT OF EXECUTIVE COMPENSATION

COMPENSATION DISCUSSION AND ANALYSIS

Composition of the Compensation Committee

The Board, upon the advice of the Compensation Committee, determines executive compensation. From June 1, 2010 to present, the Compensation committee has been comprised of Dr. Burger and Dr. Wright. Dr. Burger is chair of the Compensation Committee. The Compensation Committee met four times during the period lasting from June 1, 2010 to present.

Compensation Objectives and Philosophy

The Compensation Committee's mandate is to review and advise the Board on the recruitment, appointment, performance, compensation, benefits and termination of executive officers. The Compensation Committee also administers and reviews procedures and policies with respect to our 1993 Plan and 2003 Plan, employee benefit programs, pay equity and employment equity and reviews executive compensation disclosure where it is publicly disclosed.

The market for biotechnology companies in the development phase, particularly small capital issuers, has been extremely challenging for the past few years and throughout fiscal 2011. It has been very difficult to raise the capital required to continue our operations and meet our developmental milestones. The Compensation Committee has taken these factors into consideration when recommending the compensation for Named Executive Officers (as defined hereinafter) and focuses the assessment on achievement of the corporate objectives described below as being the key value drivers of the Corporation.

Lorus’ executive compensation program is designed to:

•

attract and retain qualified, motivated and achievement-oriented individuals by offering compensation that is competitive in the industry and marketplace;

•

align executive interests with the interests of Shareholders; and

•

ensure that individuals continue to be compensated in accordance with their personal performance and responsibilities and their contribution to the overall objectives of the Corporation.

These objectives are achieved by offering executives and employees a compensation package that is competitive and rewards the achievement of both short-term and long-term objectives of the Corporation. As such, our compensation package consists of three key elements:

Base Salary - Initial Stock Options

In establishing base salaries, the objective of the Compensation Committee is to establish levels that will enable Lorus to attract and retain executive officers that can effectively contribute to the long-term success of Lorus. Base salary for each executive officer is a function of the individual's skills, abilities, experience, past performance and anticipated future contribution to the success of Lorus. The members of the Compensation Committee use their knowledge of the industry and of industry trends to assist with the determination of an appropriate compensation package for each executive officer. In certain cases, the Compensation Committee may recommend inclusion of automobile allowances, fitness allowances and the payment of certain professional dues as a component of an overall remuneration package for executives.

In certain cases, executive officers may be granted stock options on the commencement of employment with Lorus in accordance with the responsibility delegated to each executive officer for achieving corporate objectives and enhancing Shareholder value in accordance with those objectives.

Short-Term Compensation Incentives

The role of short-term compensation incentives at Lorus is to reward corporate and personal performance. Each year, the Board approves the annual corporate objectives encompassing scientific, clinical, regulatory, business and corporate development and financial criteria. The annual cash bonus for the President and Chief Executive Officer and the other executive officers is based, at least in part, on the level of achievement of these annual objectives. One hundred percent of the President and Chief Executive Officer's and seventy-five percent of the other executive officers’ cash bonus is based on the level of achievement of corporate objectives. The balance of the other executive officers’ bonus is based on achievement of individual/departmental objectives.

All corporate and executive officer objectives are reviewed by the Compensation Committee and approved by the Board. The Compensation Committee recommends to the Board the awarding of bonuses, payable in cash, stock or stock options, to reward extraordinary individual performance.

For each executive officer, during the fiscal year ended May 31, 2011, the annual cash bonuses ranged from 15% to 40% of base salary when all corporate and individual executive officer objectives were achieved.

Cash bonuses are determined as soon as practicable after the end of the fiscal year and, for the Named Executive Officers, are included in the Summary Compensation Table in the year in respect of which they are earned.

Long-Term Incentive Plan

The role of long-term compensation incentives at Lorus is to reward an executive’s contribution to the attainment of Lorus’ long-term objectives, align an executive’s performance with the long-term performance of Lorus and to provide an additional incentive for an executive to enhance Shareholder value. Long-term incentive compensation for directors, officers, employees and consultants is reviewed annually and is accomplished through the grant of stock options under our 2003 Plan.

The number of options granted to the CEO was not based on achievement of objectives and vested over a two year period. The number of options granted for certain executives of Lorus for the fiscal year ended May 31, 2011 was based on achievement of both corporate and executive officer objectives. The Compensation Committee approves the allocation of options and options are priced using the closing market price of the Shares on the TSX on the last trading day prior to the date of grant. Options to purchase Shares expire ten years from the date of grant and vest over a term determined by the Compensation Committee. The granting of options to purchase Shares for Named Executive Officers is included in the Summary Compensation Table in the year that they are earned.

Performance Metrics

The performance of the President and Chief Executive Officer and other Named Executive Officers for the 2011 financial year was measured in the following areas:

maximizing the value of LOR-2040;

maximizing the value of LOR-253;

establishing at least one corporate partnership; and

equity financing to establish at least one year of cash.

Each of the above is weighted 25% in relation to assessment of satisfaction of overall corporate objective and determination of any general corporate bonuses. Based on these criteria the Board assigned an achievement of 70.25%. Incentive compensation related to the attainment of these objectives will be paid in fiscal 2012. Similar performance metrics were established for the fiscal year ended May 31, 2012 based on the approved business plan for the current year.

PERFORMANCE GRAPH

The following graph illustrates our cumulative total Shareholder return (assuming a $100 investment) for the Shares on the TSX as compared with the S&P/TSX Capped Health Care Index during the period May 31, 2006 to May 31, 2011.

Compensation levels for the Named Executive Officers have not fluctuated to the same degree as Shareholder returns. Compensation does not solely reflect consideration of Corporation performance. Instead, compensation is determined in light of an overall compensation package that is considered appropriate in the circumstances.

Value Vested or Earned During the Year

The following table sets forth for each director the value vested or earned on all option-based awards, share-based awards, and non-equity incentive plan compensation during the financial year ending May 31, 2011.

Name	Option-based awards - Value vested during the year ($) (2)
Mr. Herbert Abramson	Nil
Dr. Denis Burger	Nil
Dr. Mark Vincent	Nil
Mr. Warren Whitehead(1)	Nil
Dr. Jim Wright	Nil

(1)	Mr. Whitehead joined the Board on April 7, 2011 and was granted 5,000 options at that date with an exercise price of $1.05 vesting 50% upon grant and 50% on April 7, 2012. The value upon vesting was nil as the closing share price on April 7, 2010 was $1.03.

(2)	For those directors granted options on December 20, 2010 at an exercise price of $1.05, options vested 50% upon grant and 50% on December 20, 2011. The value upon vesting arose as the closing share price on December 20, 2010 was $1.03 and therefore the options did not have any value upon vesting.

INDEBTEDNESS

As of the date hereof, there is no indebtedness owing to the Corporation by any employees, officers or directors of the Corporation. The Corporation did not provide financial assistance to any employees, officers or directors for the purchase of securities during the fiscal year ended May 31, 2011 from June 1, 2011 to the date hereof.

EQUITY COMPENSATION PLAN INFORMATION

Stock Option Plans

The stock option plans were established to advance the interests of Lorus by:

•

providing Eligible Persons (as defined below) with additional incentives;

•

encouraging stock ownership by Eligible Persons;

•

increasing the interest of Eligible Persons in the success of Lorus;

•

encouraging Eligible Persons to remain loyal to Lorus; and

•

attracting new Eligible Persons to Lorus.

Our original stock option plan, the 1993 Plan, was established in 1993; however, due to significant developments in the laws relating to share option plans and our then future objectives, in November 2003 we created the 2003 Plan, ratified by our Shareholders, pursuant to which all future grants of stock options would be made.

The Compensation Committee as authorized by the Board administers the 1993 Plan and the 2003 Plan (collectively the “Stock Option Plans”).

The 1993 Plan

Under the 1993 Plan, options were granted to directors, officers, consultants and employees of the Corporation or its subsidiaries (“Eligible Persons”). The total number of options issued under the 1993 Plan is 2,749. This represents 0.0% of the Corporation's issued and outstanding capital as at October 28, 2011. There were no further option grants made under the 1993 Plan after November 2003. Therefore, no further options are issuable under the 1993 Plan. The total number of Shares issuable under actual grants pursuant to the 1993 Plan is 2,749 being 0.0% of the Corporation's issued and outstanding capital as at October 28, 2011.

The number of Shares issuable to insiders, at any time, under the 1993 Plan and any other compensation arrangement of the Corporation cannot exceed 10% of the issued and outstanding Shares of the Corporation. The number of Shares issued to insiders, within any one year period, under the 1993 Plan and any other compensation arrangement of the Corporation cannot exceed 10% of the issued and outstanding Shares of the Corporation. The maximum percentage of Shares reserved for issuance to any one person is 5% of the issued and outstanding Shares of the Corporation. The exercise price of options granted under the 1993 Plan was established by the Board on the basis of the closing market price of Shares of the Corporation on the TSX on the last trading day preceding the date of grant. If such a price was not available, the exercise price was to be determined on the basis of the average of the bid and ask for the Shares on the TSX on the date preceding the date of grant. The Board determined the vesting period of options at the time of granting the option. The term of options granted under the 1993 Plan and outstanding as of October 28, 2011 is 10 years from the date of grant.

If an option holder ceases to be an officer, director, continuing consultant or employee of the Corporation or a subsidiary, each unexpired, vested option may be exercised within three months of the date of cessation. In the event of the death of an optionee, each unexpired, vested option may be exercised within nine months of the option holder's date of death.

Options granted under the 1993 Plan are not transferable. Currently, the 1993 Plan may be amended by the Board subject to regulatory approval in certain circumstances.

The 2003 Plan

Under the 2003 Plan, options may be granted to Eligible Persons. At October 2, 2011, the total number of options outstanding under the 2003 Plan is 1,166,792 representing 5.5% of the Corporation's issued and outstanding capital. Options to purchase up to an additional 2,005,770 Shares, being 9.5% of Shares issued and outstanding, will be available for grant under the 2003 Plan if the Unallocated Options are approved by the Shareholders at the Meeting. The total number of Shares issuable under the 2003 Plan is 15.0% of the Corporation's issued and outstanding capital as at October 28, 2011 which represents 3,175,311 Shares. The total number of options issued under the 2003 Plan combined with those issued under the 1993 Plan and Shares issued under the ACP will not exceed 15% of the Shares issued and outstanding at any time.

The maximum number of Shares reserved for issuance to insiders, at any time, under the 2003 Plan and any other compensation arrangement of the Corporation is 10% of the issued and outstanding Shares of the Corporation. The maximum number of Shares that may be issued to insiders, at any time, under the 2003 Plan and any other compensation arrangement of the Corporation within a 12 month period is 10% of the issued and outstanding Shares of the Corporation. The maximum number of Shares reserved for issuance to any one person is 5% of the issued and outstanding Shares of the Corporation. The exercise price of options granted under the 2003 Plan is established by the Board and will be equal to the closing market price of the Shares on the TSX on the last trading day preceding the date of grant. If there is no trading on that date, the exercise price will be the average of the bid and ask on the TSX on the last trading date preceding the date of grant. If not otherwise determined by the Board, an option granted under the 2003 Plan will vest as to 50% on the first anniversary of the date of grant of the option and an additional 25% on the second and third anniversaries after the date of grant. The Board fixes the term of each option when granted, but such term may not be greater than 10 years from the date of grant.

If an option holder is terminated without cause, resigns or retires, each option that has vested will cease to be exercisable thee months after the option holder's termination date. Any portion of an option that has not vested on or prior to the termination date will expire immediately. If an option holder is terminated for cause, each option that has vested will cease to be exercisable immediately upon the Corporation's notice of termination. Any portion of an option that has not vested on or prior to the termination date will expire immediately.

Options granted under the 2003 Plan are not assignable.

Currently, the Board may amend the 2003 Plan subject to regulatory approval, provided that the Board may not make the following amendments without the approval of Shareholders:

•

an amendment to the maximum number of Shares reserved for issuance under the 2003 Plan and under any other security based compensation arrangement of the Corporation;

•

a reduction in the exercise price for options held by insiders;

•

an extension to the term of options held by insiders; and

•

an increase in the 10% limits on grants to insiders.

During the period June 1, 2010 to May 31, 2011, options to purchase 1,049,700 Shares were granted under the 2003 Plan at exercise prices between $0.89 and $1.05 per Share. During the year ended May 31, 2011, we granted options to employees, other than executive officers of the Corporation, to purchase 78,500 Shares, being 7% of the total incentive stock options granted during the year to employees, executive officers and directors.

Alternative Compensation Plan

On November 30, 2009, after receiving shareholder approval, the Corporation adopted an ACP which enables Lorus to meet its obligations to pay directors’ fees, salary and performance bonuses to certain employees in the form of Shares. The ACP permits the Corporation to, in circumstances considered appropriate by the Board, encourage the ownership of equity of the Corporation by its directors and senior employees (“Participants”), enhance the Corporation’s ability to retain key personnel and reward significant performance achievements while preserving the cash resources of the Corporation.

Under the ACP, Participants have the option of receiving director’s fees, salary, bonuses or other remuneration, as applicable (“Remuneration”) by the allotment and issuance from treasury of such number of Shares as will be equivalent to the cash value of the Remuneration determined by dividing the Remuneration by the weighted average closing Share price for the five (5) trading days prior to payment date (the “5-day VWAP”). The issue price of Shares issued under the ACP is the 5-day VWAP.

The maximum number of Shares reserved for issuance under the ACP, when combined with the Stock Option Plans, will not exceed 15% of the Corporation’s issued and outstanding Shares at any given time.

There have been no Shares issued under the ACP.

Employee Share Purchase Plan

We have an Employee Share Purchase Plan (“ESPP”) with the purpose of the ESPP to assist the Corporation to retain the services of its employees, to secure and retain the services of new employees and to provide incentives for such persons to exert maximum efforts for the success of the Corporation. The ESPP provides a means by which employees of the Corporation and its affiliates may purchase Shares at a 15% discount through accumulated payroll deductions. Eligible participants in the ESPP include all employees, including executive officers, who work at least 20 hours per week and are customarily employed by the Corporation or an affiliate of the Corporation for at least six months per calendar year. Generally, each offering is of three months' duration with purchases occurring every quarter. Participants may authorize payroll deductions of up to 15% of their base compensation for the purchase of Shares under the ESPP.

For the fiscal year ended May 31, 2011, a total of 6,652 Shares had been purchased by employees under the ESPP at prices per Share between $1.27 and $0.68 per Share and a weighted average purchase price of $0.83. During the fiscal year ended May 31, 2011, under the ESPP, Named Executive Officers, as a group did not purchase any Shares.

Directors' and Officers' Deferred Share Unit Plan

We have a deferred share unit plan for directors and officers (the “Deferred Share Unit Plan”). Under the Deferred Share Unit Plan, participating directors (“Participating Directors”) may elect to receive either a portion or all of their annual fees for acting as a director (“Annual Fees”) from us in deferred share units. Under the Deferred Share Unit Plan, the Compensation Committee may at any time during the period between the annual meetings of our Shareholders, in its discretion recommend the Corporation credit to each participating director who has elected under the terms of the Deferred Share Unit Plan, the number of units equal to the gross amount of the Annual Fees to be deferred divided by the fair market value of the Shares. The fair market value of the Shares is determined as the closing price of the Shares on the TSX on the day immediately preceding such recommendation by the Compensation Committee or such other amount as determined by the Board and permitted by the stock exchanges or other market(s) upon which the Shares are from time to time listed for trading and by any other applicable regulatory authority (collectively, the “Regulatory Authorities”).

In addition, the Participating Directors may elect under the Deferred Share Unit Plan to receive deferred share units in satisfaction for meeting fees earned by the Participating Directors as a result of attendance at meetings of the Board held between the annual meetings of our Shareholders by the credit to each Participating Director of the number of units equal to the gross amount of the meeting fees to be deferred divided by the fair market value of the Shares, being the closing price of the Shares on the TSX on the day immediately preceding the recommendation by the Compensation Committee or such other amount as determined by the Board and permitted by the Regulatory Authorities.

The Deferred Share Unit Plan is administered by the Board (in consultation with the Compensation Committee) and, subject to regulatory requirements, may be amended by the Board without Shareholder approval. When a Participating Director ceases to hold the position of director and is no longer otherwise employed by us, the Participating Director receives either (a) a lump sum cash payment equal to the number of deferred share units held multiplied by the then fair market value of the Shares on the date of termination, or (b) the number of Shares that can be acquired in the open market with the amount described in (a), either case being subject to withholding for income tax. The Board may terminate the Deferred Share Unit Plan any time before or after any allotment or accrediting of deferred share units thereunder.

APPENDIX A

Corporate Governance Practices

Lorus Therapeutics Inc. (the “Corporation”) is committed to sound and comprehensive corporate governance policies and practices and is of the view that its corporate governance policies and practices, outlined below, are comprehensive and consistent with National Policy 58-201 - Corporate Governance Guidelines (“NP 58-201”), and National Instrument 52-110 - Audit Committees (“NI 52-110”).

Board of Directors

Composition of the Board

The Corporation's Board is currently composed of five directors, and the proposed Board will be composed of five directors, a majority of whom are independent directors. An “independent” board member, as further defined in NI 52-110, means that such member has no “material relationship” with the issuer. A “material relationship” is a relationship that could, in the view of the Board, be reasonably expected to interfere with the exercise of a member's judgment. Each year the board reviews the composition of the board and assesses whether a board member is “independent”.

Director	Independent

Herbert Abramson	Yes
Denis Burger	Yes
Mark Vincent	Yes
Jim A. Wright	Yes
Aiping Young	No

Aiping Young, the President and Chief Executive Officer (“CEO”) of the Corporation, is not an independent director by virtue of her role on the Corporation's management team.

The independent directors hold meetings as a matter of routine after each Board meeting, without the presence of non-independent directors and members of management. There were three meetings of the independent directors in the fiscal year ended May 31, 2011.

Denis Burger, the chair of the Board (the “Chair”) is an independent director.
