MANAGEMENT INFORMATION CIRCULAR                                  MARSULEX


The purpose of the annual meeting of shareholders of Marsulex Inc. (the
"Meeting") is to elect directors, to appoint auditors and to receive the 2004
financial statements of the Company.

THE CORPORATION

Marsulex Inc. ("Marsulex" or the "Company") was amalgamated under the laws of
Canada by a Certificate of Amalgamation dated June 16, 1989. By a Certificate
of Amendment dated June 16, 1989, the Company amended its articles to remove
the private company restrictions. By a Certificate of Amendment dated November
19, 1996, Marsulex amended its articles by, among other things, changing the
minimum and maximum number of directors, amending the authorized capital and
reclassifying certain classes of shares to prepare for a rights offering.

PROXY SOLICITATION AND VOTING AT THE MEETING

Solicitation of Proxies by Management

This Management Information Circular is furnished in connection with the
solicitation by management of Marsulex of proxies to be used at the Company's
Meeting to be held on Thursday, May 19, 2005 at 3:00 p.m. (Toronto time) at
St. Andrew's Club and Conference Centre, 27th Floor, 150 King Street West,
Toronto, Ontario, Canada M5H 1J9. The costs of such solicitation will be borne
by the Company. The solicitation will be primarily by mail. However, the
directors, officers and employees of the Company may also solicit proxies by
telephone, facsimile or in person. The information contained herein, unless
otherwise indicated, is given as at March 1, 2005.

The persons specified in the enclosed form of proxy are representatives of
management and are directors and/or officers of the Company. Each shareholder
has the right to appoint a person (who need not be a shareholder of the
Company) other than the persons designated in the enclosed form of proxy, to
attend and act for the shareholder and on the shareholder's behalf at the
Meeting or any adjournment or postponement thereof. This right may be
exercised by striking out the names of the designated persons on the form of
proxy and inserting the name of the shareholder's nominee in the space
provided, or by completing another appropriate form of proxy. In either case,
the proxy form must be dated and be executed by the shareholder, or his or her
attorney authorized in writing. To be valid, proxies must be returned in the
enclosed envelope or deposited with the Company's transfer agent,
Computershare Trust Company of Canada ("Computershare"), at 100 University
Avenue, 9th Floor, Toronto, Ontario M5J 2Y1 Attention: Proxy Department.
Computershare must receive your proxy no later than 5:00 p.m. (Toronto time)
on May 18, 2005 or, if the Meeting is adjourned, 48 hours (excluding Saturdays
and statutory holidays) before any reconvened Meeting.

Only registered holders of common shares of the Company, or the persons they
appoint as their proxies, are permitted to attend and vote at the Meeting.
However, in many cases, common shares of the Company that are 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, such as,
      among others, 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) of which the Intermediary is a participant.



                                    IC - 3
<PAGE>


In accordance with the requirements of National Instrument 54-101, the Company
will distribute copies of the Notice of Meeting, this Management Information
Circular, the form of proxy and the 2004 annual report (which includes
management's discussion and analysis) (collectively, the "Meeting Materials")
to the clearing agencies and Intermediaries for onward distribution to
Non-Registered Holders. Intermediaries are required to forward Meeting
Materials to Non-Registered Holders unless a Non-Registered Holder has waived
the right to receive them. Very often, Intermediaries will use service
companies to forward the Meeting Materials to Non-Registered Holders.
Generally, Non-Registered Holders who have not waived the right to receive
Meeting Materials will either:

(a)   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 shares beneficially owned by the Non-Registered Holder but
      which is otherwise uncompleted. This form of proxy need not be signed by
      the Non-Registered Holder. In this case, the Non-Registered Holder who
      wishes to submit a proxy should otherwise complete the form of proxy in
      accordance with its directions and deposit it with Computershare at 100
      University Avenue, 9th floor, Toronto, Ontario, M5J 2Y1 Attention: Proxy
      Department; or

(b)   be given a voting instruction form which must be completed and signed by
      the Non-Registered Holder in accordance with the directions on the
      voting instruction form (which may in some cases permit the completion
      of the voting instruction form by telephone).

The purpose of these procedures is to permit Non-Registered Holders to direct
the voting of the shares they beneficially own. Should a Non-Registered Holder
who receives either a proxy or a voting instruction form 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
that form. In either case, Non-Registered Holders should carefully follow the
instructions of their Intermediaries and their service companies.

VOTING IN PERSON

If you attend the Meeting in person, and are a registered shareholder, you can
cast one vote for each of your registered common shares on any or all
resolutions put before the Meeting. You may dissent from any matter proposed
at the Meeting by withholding from voting your common shares for the
resolutions at the Meeting.

VOTING OF PROXIES AND EXERCISE OF DISCRETION

The common shares of the Company (the "Common Shares") represented by proxies
in favour of the management representatives will be voted (or withheld from
voting) by the persons named in the form of proxy in accordance with the
directions of the shareholder appointing them. In the absence of any direction
to the contrary, it is intended that the Common Shares represented by proxies
in favour of the management representatives will be voted on any ballot for
the election of the directors and for the appointment of auditors, as
described in this Management Information Circular. The enclosed form of proxy
confers discretionary authority upon the persons named therein with respect to
matters not specifically mentioned in the Notice of Meeting but which may
properly come before the Meeting or any adjournment or postponement thereof.
At the date of this Management Information Circular, management knows of no
such amendments, variations or other matter to come before the Meeting other
than the matters referred to in the Notice of Meeting and routine matters
incidental to the conduct of the Meeting. If any further or other matter is
properly brought before the Meeting, the persons designated in the enclosed
form of proxy will vote thereon in accordance with their best judgement
pursuant to the discretionary authority conferred by such proxy with respect
to such matters.

REVOCABILITY OF PROXIES

A proxy given pursuant to this solicitation may be revoked, as to any motion
on which a vote has not already been cast pursuant to the authority conferred
by it, by instrument in writing, including another proxy bearing a later date,
executed by the shareholder or by his or her attorney authorized in writing
or, if the shareholder is a body corporate, by an officer or attorney thereof
duly authorized, and deposited either at the registered office of the Company
at any time up to and including the last business day preceding the day of the
Meeting or any adjournment or postponement thereof, or with the chair of the
Meeting on the day of the Meeting, or any adjournment or postponement thereof,
or in any other manner permitted by law.


                                    IC - 4
<PAGE>


A Non-Registered Holder may revoke a voting instruction form or a waiver of
the right to receive Meeting Materials and to vote given to an Intermediary at
any time by written notice to the Intermediary, except that an Intermediary is
not required to act on a revocation of a voting instruction form or of a
waiver of the right to receive Meeting Materials and to vote that is not
received by the Intermediary at least seven days prior to the meeting.

VOTING SHARES AND PRINCIPAL HOLDERS THEREOF

The holders of record of Common Shares as at the close of business on March
23, 2005 (the "Record Date") are entitled to receive notice of the Meeting and
will be entitled to vote at the Meeting, except that a transferee of such
Common Shares acquired after the Record Date shall be entitled to vote the
transferred Common Shares at the Meeting if he or she produces properly
endorsed certificates for such Common Shares or otherwise establishes that he
or she owns such Common Shares and demands, by written request delivered to
the Corporate Secretary of the Company at its registered office (111 Gordon
Baker Road, Suite 300, Toronto, Ontario, M2H 3R1) no later than May 18, 2005,
that his or her name be included in the list of shareholders entitled to vote
at the Meeting.

As of March 1, 2005, Marsulex had 32,035,231 Common Shares issued and
outstanding. Each Common Share entitles the holder thereof to one vote.

To the knowledge of the directors and officers of the Company, the only person
or corporation which beneficially owned on March 1, 2005, directly or
indirectly, or who on such date exercised control or direction over more than
10% of the voting rights attached to any class of voting securities of the
Company outstanding on the Record Date is TD Capital Canadian Private Equity
Partners ("TD Capital"), a Toronto-Dominion Bank fund, which directly and
indirectly owned 18,364,279 Common Shares representing approximately 57.3% of
the outstanding Common Shares on that date.

PARTICULARS OF MATTERS TO BE ACTED UPON

1.    ELECTION OF DIRECTORS

The Articles of the Company provide that the Company shall have a minimum of
three directors and a maximum of fifteen directors. The number of directors to
be elected at the Meeting has been fixed at eight. The term of office for each
of the present directors will expire at the Meeting when a successor is
elected. Each director elected at the Meeting shall hold office until the next
annual meeting of shareholders or, subject to the Company's by-laws and to
applicable laws, until such office is earlier vacated.

The management representatives designated in the enclosed form of proxy intend
to vote for the election, as directors, of the proposed nominees whose names
are set out below. All of the nominees are now directors and have been
directors of the Company since the dates set out opposite their names. Subject
to the proposed nominees' acceptance of a directorship, management does not
expect that any of the proposed nominees will be unable to serve as a
director. However, if any of the proposed nominees are for any reason unable
to serve as a director, the persons named in the enclosed form of proxy will
use their best judgement in voting for an alternative nominee.

The following table sets forth the names of and certain additional information
for the persons proposed to be nominated for election as directors of the
Company. Current members of each of the four standing committees of the Board
of Directors are indicated by footnote. The Company does not have an executive
committee of the Board.

OPTION REPRICINGS

The Company has not repriced downward any options since inception of the Stock
Option Plan (described below).

SETTLEMENT AGREEMENT WITH FORMER CEO

In November 2004, the Company entered into a settlement agreement with David
Gee, the former President and CEO of the Company. The total cost of payments
to Mr. Gee in connection with his departure from the Company pursuant to the
settlement agreement amounted to $4,287,886. This amount represents the
payment of (i) a settlement award calculated using years of service with the
Company and the years of service with the prior employer, (ii) the bonus in
respect of service for the 2004 year, (iii) a lump sum retiring allowance, and
(iv) a lump-sum contribution made in respect of a supplemental pension plan
(described below). Also pursuant to the settlement agreement, the Company
agreed to continue to make its premium contributions so as to provide for
certain benefits (including life and health care insurance) until the earlier
of (a) June 30, 2007 and (b) the date Mr. Gee secures comparable benefit
coverage. Under the terms of the settlement agreement, all performance share
units and stock options held by Mr. Gee (under the plans described below), to
the extent then not vested, vested immediately.

SUPPLEMENTAL PENSION PLAN FOR FORMER CEO

In 1999, the Company established a Supplemental Pension Plan (the "Plan") for
David Gee. The Plan was structured to provide Mr. Gee with an annual target
pension income upon retirement at age 65 of $291,903. This target pension
income was based on (1) Mr. Gee's approximately 9.5 years of service at a
previous employer, as well as his projected 17 years of service at the Company
to age 65, and (2) a projected average salary based on a 4% annual increase to
base salary together with bonuses over the 17 years of service. Pursuant to
the Plan, after taking into consideration the income generated from the
existing group registered retirement savings plan and Mr. Gee's pension from
the previous employer, the Company determined that an annual payment of
approximately $130,000 (including $10,000 estimated expenses) into the Plan
would achieve the desired target pension income. In 2002, a review of
contributions determined that funding in 2000 and 2001 was insufficient to
meet the pension objectives for those years due to overstated interest


                                    IC - 8
<PAGE>

components used in the funding estimate software. An additional contribution
of $53,430 was made by the Company to bring the Plan to appropriate 2002
objective levels. Pursuant to the settlement agreement entered into with Mr.
Gee (as described above), the Company has satisfied its obligations with
respect to the Plan.

REPORT ON EXECUTIVE COMPENSATION BY THE HUMAN RESOURCES AND COMPENSATION
COMMITTEE

The Human Resource and Compensation Committee (the "HRCC") assists the Board
of Directors in establishing the compensation philosophy for the Company and
reviewing the design, competitiveness and implementation of the Company's
compensation and benefit plans. The HRCC annually reviews the performance of
the President and Chief Executive Officer and, together with the President and
Chief Executive Officer, the performance of senior management.

The HRCC regularly retains independent compensation consultants (for example,
Aon was retained in 2004) to assist with reviews of the Company's compensation
programs. This review compares the Company's program with those of selected
comparable companies in the industrial services industries and other small to
mid-sized Canadian and U.S. companies. The HRCC believes that this review
process provides an effective, ongoing evaluation of the program relative to
current industry practice.

The HRCC also reviews and monitors management succession processes and
provides assistance to the President and Chief Executive Officer on senior
management appointments.

Four Board members, all outside directors, served on the HRCC in 2004: Robert
Yohe (Chair), Ian Matheson, Lee Stewart and David McCann. Ian Matheson served
until December 2, 2004 when he was replaced by Mr. Stewart.

The objectives of the Company's compensation program are to attract and retain
highly qualified senior management, motivate superior performance and align
the interests of senior management with the interests of the Company's
shareholders. The compensation program is linked to achieving both short-term
and longer-term goals of the Company. Accordingly, a significant portion of
senior management's compensation is based upon the Company's success in
meeting specified performance goals, including strategic plan objectives and
appreciation in the Company's share price.

The Company's compensation program for senior management is composed of 3
components: (1) base salary, (2) annual incentive awards for the
accomplishment of specific goals and objectives, and (3) long-term rewards for
increasing shareholder value.

(1)   Base Salary

      The Company maintains base salary guidelines derived from an assessment
      of relative duties and responsibilities with corresponding salary ranges
      for each position targeted to deliver compensation at or about the
      market median. The HRCC reviews the base salary structure on an annual
      basis for equity, consistency with performance, and competitiveness.

(2)   Annual Short-Term Incentive Awards

      Under the short-term incentive compensation plan, senior management
      members are eligible for annual bonuses based on (a) the Company's
      success in achieving defined performance targets based on earnings
      before interest, taxes, depreciation and amortization (EBITDA) and
      return on capital (ROC), and (b) their individual success in
      accomplishing the personal goals and expectations as determined and set
      out in their objectives each year. The plan participants, their rates of
      participation, the minimum standards required to qualify for awards and
      the criteria used to determine awards under the plan are established
      annually by the HRCC and recommended to the Board of Directors. The HRCC
      sets the annual objectives and reviews the performance of the President
      and Chief Executive Officer, with confirmation by the Board, while the
      President and Chief Executive Officer sets the annual objectives and
      reviews the performance of the other Named Executives, with confirmation
      by the HRCC.

      The President and Chief Executive Officer, and Chief Financial Officer
      are eligible to earn target bonuses of 50% and 35%, respectively, of
      their base salaries, with both awards based 60% on the achievement of
      targeted consolidated results and 40% on the achievement of individual
      performance objectives. The other Named Executives are eligible to earn


                                    IC - 9
<PAGE>

      target bonuses of 35% of their base salaries, based 20% on the
      achievement of targeted consolidated results, 40% on the achievement of
      targeted results of their respective business segments, and 40% on the
      achievement of individual performance objectives. Under this plan, the
      participants can earn bonuses in excess of their targets in the event
      that targeted consolidated results, targeted business segment results,
      and/or individual performance objectives are exceeded.

(3)   Long-term Rewards

      All Named Executives participate in an incentive compensation plan under
      which they are entitled to long-term awards based on the Company's
      success in achieving return on capital objectives. The HRCC determines
      the annual plan targets each year, subject to the approval of the Board.

Performance Share Unit Plan and Deferred Share Unit Plan (Executives)

In 2002, the Company established a Performance Share Unit Plan (the "PSU
Plan") to provide long-term incentive compensation for management employees
and key persons that emphasizes pay for performance. Grants under the PSU Plan
are made at the discretion of the Board, which also prescribes the performance
factors (measured by the Company's return on capital) used to determine the
number of performance share units (PSU's), which will vest at the expiry of
the grant period. Plan participants who elect not to participate in the
Deferred Share Unit Plan (described below) and who continue to be employed by
the Company at the expiry of the grant period, will be entitled to that number
of Marsulex common shares that can be purchased on the open market with an
amount equal to the number of vested PSU's multiplied by the then market value
of the common shares less all applicable source deductions.

The Company also established a Deferred Share Unit Plan (Executives) (the "DSU
Plan") for management employees and key persons to defer until retirement,
termination, resignation or death, delivery to the participant of the
underlying common shares of Marsulex and the concomitant requirement for the
payment of taxes associated therewith. Unless a participant elects otherwise,
vested PSU's automatically convert on a one-for-one basis to deferred share
units (DSU's) at the expiry of the grant period. On the settlement date (a
date between the date of retirement, termination, resignation or death and the
end of the following calendar year), a participant is entitled to receive a
number of common shares of the Company purchased on the open market, or cash,
or a combination of such shares and cash at his/her discretion. The
entitlement amount is the amount of DSU's multiplied by then market value of
the shares less all applicable source deductions.

Stock Option Plan

The Company has a stock option plan for management employees and key persons
(the "Stock Option Plan"). Persons generally employed by the Company in
management functions, senior officers and directors of the Company, or an
affiliate of the Company, are eligible to participate in the Stock Option
Plan. Participants are determined by the HRCC and confirmed by the Board. The
number of Common Shares issuable under the Plan cannot, at present, exceed
3,120,227. Options are to be issued with an exercise price of not less than
the closing price of the Common Shares on the Toronto Stock Exchange on the
day prior to the issuance and are to be exercisable for up to a maximum of ten
years. The Board may, in granting options, provide that the right to exercise
the options vests over a specified period. In such a case, the options
nevertheless become automatically exercisable in full if control over the
Company changes. If a participant's employment is terminated due to death or
voluntary resignation, or if a director participant leaves the Board, the
vesting of options held by such participant automatically ceases and vested
options may not be exercised by the participant after the earlier of the first
anniversary of such termination and the expiry of the options. If a
participant's employment is terminated otherwise than for cause, the vesting
of options held by the participant continues during the notice period
established by the participant's employment contract or otherwise and vested
options held by the participant may be exercised until the option's expiry
period. No financial assistance is provided by the Company to assist grantees
of options to purchase Common Shares.

In 2002, the Company discontinued the use of stock options for long-term
incentive compensation and replaced them with grants under the PSU Plan.

Review of President and Chief Executive Officer Compensation

In determining the 2004 long-term incentive award for Laurie Tugman, President
and Chief Executive Officer of the Company, the HRCC took into consideration
Mr. Tugman's performance against his 2004 goals and objectives as Chief
Operating Officer established by the Board of Directors. These included the
Company's actual 2004 performance against specific metrics reviewed and
approved by the Board of Directors, as well as the accomplishment of specific
operational and organizational objectives, including the agreements for the
expansion of the Montreal Facility, the recertification under the Responsible
Care initiative and the continued improvement of responsible management
processes in this area. Mr. Tugman was awarded incentive compensation of
$105,000 in consideration of his successful accomplishment of the above
objectives. A total of 62,435 performance share units were granted to Mr.
Tugman in March of 2005 under the Company's PSU Plan.

STOCK OWNERSHIP GUIDELINES

In order to better align senior management's interests with those of the
Company's shareholders, the Company has adopted minimum stock ownership
guidelines. Under these guidelines, executives (including the Named
Executives) are expected to accumulate and hold common stock, performance
share units and vested "in-the-money" stock options (as described above) in
accordance with the following table:

PERFORMANCE GRAPH

The following graph compares the total cumulative shareholder return for $100
invested in common shares of the Company with the total cumulative return of
the S&P/TSX Composite Index over the last five years. On December 31, 2004,
the Company's Common Shares closed at $7.00.


The omitted graph indicates that a $100 investment in common shares of the
Company on January 1, 1999 would have had a value of approximately $219 on
December 31, 2004. The omitted graph also indicates that the same $100
investment in the S&P/TSX Composite Index on January 1, 1999 would have had a
value of approximately $119 on December 31, 2004.


EMPLOYMENT CONTRACTS

All of the Named Executives are parties to offer letters with the Company,
which outline the terms and conditions pertaining to their employment. In
addition to the compensation under the heading "Executive Compensation" above,
these contracts provide as follows:

In the case of Laurie Tugman, if Mr. Tugman's employment is terminated for any
reason other than for cause, the Company is obligated to continue to pay Mr.
Tugman's total compensation, including benefits and car allowance, for a
period of 24 months. In the case of Ted Irwin, if Mr. Irwin's employment is
terminated as a result of a sale of the Company, the Company is obligated to
pay Mr. Irwin severance of 12 months salary and benefits. If Mr. Irwin's
employment is terminated for any other reason other than for cause, the
Company is obligated to pay him severance of 9 months (12 months on or after
March 2007) salary and benefits. In the case of Robert Cardell, if Mr.
Cardell's employment is terminated by the Company for any reason other than

COMPENSATION OF DIRECTORS

No fees are paid to Messrs. Lambert, McCann or Stevens for acting as directors
of the Company. Every other director of the Company is entitled to receive an
annual retainer of $15,000, meeting fees in the amount of $1,500 per meeting
and committee meeting fees of $500 per meeting. A director who is the chair of

<PAGE>


a committee of the Board receives an additional annual retainer of $3,000
which retainer was increased to $4,500 effective March 1, 2005.

In 2002, the Company established a Deferred Share Unit Plan (Directors) (the
"DSU Directors' Plan") pursuant to which a director can elect to receive no
less than 25% and up to 100% of his annual retainer in deferred share units
(DSU's) in lieu of cash or shares. If a director elects to so receive 100% of
his annual retainer in the form of DSU's, he may also elect to receive 100% of
his meeting fees and committee chair fees in the form of DSU's in lieu of a
cash payment. On the settlement date (based on the date of resignation or
death), a director will be entitled to receive, at his option, common shares
of the Company, cash, or a combination of cash and shares in satisfaction of
the DSU's. A cash payment or an amount to be used to purchase shares on the
open market is the number of DSU's credited to a director's account multiplied
by the then market price of the shares less all applicable source deductions.
In 2004, a total of 14,410 DSU's were credited to the accounts of directors
who elected to participate in the DSU Plan.

Directors (other than Messrs. Lambert, McCann and Stevens) are also eligible
to participate in the Company's Stock Option Plan and PSU Plan. No options
were granted to directors in 2004. A total of 12,865 PSU's were granted to
eligible directors in 2004.

Company.

INTEREST OF INFORMED PERSONS IN MATERIAL TRANSACTIONS

No informed person (as defined in Material Instrument 54-102) of the Company,

applicable to all insured directors and officers under the current policy,

3.    GENERAL MATTERS

STATEMENT OF CORPORATE GOVERNANCE PRACTICES

The Board of Directors and management of Marsulex believe that sound corporate
governance practices are an important part of the Company's business
operations. They therefore support the guidelines of the Toronto Stock
Exchange's Corporate Governance Committee (the "Guidelines") and believe that
the Company's governance procedures conform to those Guidelines. (The
paragraph numbers below correspond to the subsection numbers of the Guidelines
as set out in the Toronto Stock Exchange Company Manual, section 474.)

2.    The Mandate of the Marsulex Board is consistent with the TSX's
      requirement that a board assume responsibility for the stewardship of a
      corporation. The Company's Mandate is reviewed annually and includes the
      following responsibilities:

      (a)   adoption and reassessment of the strategic plan for the Company;
      (b)   identification of principal risks associated with the Company's
            business and review of systems to manage these risks;
      (c)   assessment of senior management and consideration of succession
            planning;
      (d)   adoption of communications policy for the Company; and
      (e)   review of internal control and management information systems.

      The Board has established four standing committees to assist in this
      stewardship function. Each committee is composed of outside directors,
      the majority of which (except in the case of the Environmental, Health &
      Safety Committee) are unrelated to the Company.

      Human Resources and Compensation Committee - This Committee is
      responsible for assisting the Board in determining compensation of
      senior management as well as reviewing the adequacy and form of
      directors' compensation. The Committee annually reviews the goals and
      objectives of the Chief Executive Officer and the Chief Financial
      Officer for the upcoming year and each year conducts an appraisal of the
      performance of the Chief Executive Officer and the Chief Financial
      Officer.

      Audit Committee - The Committee is responsible for assisting the Board
      in fulfilling its oversight responsibility of the Company's financial
      reporting, public disclosure policy, accounting systems, internal
      controls and financial risk management and liaising with the external
      auditors.

      Environmental, Health and Safety Committee - This Committee is
      responsible for assisting the Board in monitoring environmental, health
      and safety issues. Responsibilities include policies on employee health
      and safety, the environment, product responsibility, and the
      transportation of hazardous materials. On a regular basis, the Committee
      commissions and reviews external audits related to Marsulex's compliance
      and reviews management's activities with respect to correcting any
      deficiencies.


                                   IC - 14
<PAGE>

      Corporate Governance Committee - This Committee is responsible for
      developing the Company's approach to corporate governance issues,
      advising the Board in filling vacancies on the Board and periodically
      reviewing the composition and effectiveness of the Board and the
      contribution of individual directors.

3.    The Board is currently composed of eight members. Three of the current
      directors are considered to be related to the Company. TD Capital
      controls a majority of the votes for the election of directors and as
      such is considered to be the Company's "significant shareholder" under
      the Guidelines.

4.    Each year the Board, assisted by the Corporate Governance Committee,
      undertakes an analysis of each director's relationship with the Company
      to determine if any are "related" as contemplated by the Guidelines. In
      December 2004, consideration was given, once again, to past and present
      engagement of the director's professional services or the services of a
      company in which the director has an interest, the significance of any
      remuneration for that engagement, and other business or interests which
      could reasonably be perceived to materially interfere with that
      director's ability to act in the best interests of the Company. The
      "related" directors are: Roderick Barrett, a partner in Stikeman Elliott
      LLP, solicitors to the Company and Ian Matheson, employed by Risk
      Management Consultants of Canada Limited, a risk management company
      providing consulting services to the Company.

      The Board has considered the relationship of each of the directors to TD
      Capital, the Company's significant shareholder, and determined Messrs.
      David McCann and William Lambert (Managing Directors of TD Capital) and
      William Stevens (Vice President and Director of TD Capital) to be
      related to the significant shareholder. The Board believes that the
      composition of the Board, being comprised of a majority of persons who
      do not have a relationship with the significant shareholder, fairly
      reflects the interests of minority shareholders in the Company.

5.    The mandate of the Corporate Governance Committee includes the
      responsibility for assisting the Board in filling vacancies on the
      Board.

6.    The mandate of the Corporate Governance Committee also includes an
      annual review of the performance of the Board, committees of the Board,
      and if deemed appropriate, individual directors.

7.    The Board does not have a formal orientation program for new directors.
      However, new directors meet with management to review the business of
      the Company and are provided with certain historical documentation and
      materials from recent previous Board and committee meetings.

8.    The mandate of the Corporate Governance Committee includes the periodic
      review of the composition of the Board. While the Board feels that its
      current size is conducive to the supervision of the business of the
      Company and the efficient evaluation of business opportunities, the
      Board views the addition of outside and unrelated directors as desirable
      and will expand the Board to accommodate candidates with exceptional
      qualifications.

9.    The Compensation Committee reviews the adequacy and form of directors'
      compensation on an annual basis. Each director is paid an annual
      retainer, attendance fees, committee chair fees (if appropriate) and
      they are also eligible to participate in the Company's Stock Option
      Plan, Performance Share Unit Plan, and Deferred Share Unit Plan
      (Directors). The Board believes that the directors' compensation package
      realistically reflects the responsibilities and risk involved in being
      an effective director.

10.   The Compensation and Corporate Governance Committees are comprised of
      three directors, all of whom are outside directors and the majority of
      whom are unrelated to the Company. The Audit Committee is comprised of
      three directors, all of whom are outside directors and are unrelated to
      the Company. The Environmental, Health & Safety Committee is comprised
      of 2 directors both of whom are outside directors and one of whom is
      unrelated to the Company.

11.   The Corporate Governance Committee is responsible for developing the
      Company's approach to corporate governance, including this Statement.

12.   In connection with the appointment of the President and Chief Executive
      Officer in November 2004, the position description of this office was
      reviewed and updated. The compensation of the President and Chief
      Executive Officer is directly tied to the successful completion of
      objectives determined and evaluated by the Board, assisted by the
      Compensation Committee. In addition, the Company has an Authorizations
      Policy, approved by the Board, which sets out the limits of each
      officer's authorization by financial and other parameters.


                                   IC - 15
<PAGE>

13.   The Board of Directors has appointed a Chair, Mr. David McCann, who is
      not a member of management and is not related to the Company, but is
      related to the Company's significant shareholder. The Company has a
      policy formalizing the opportunity afforded to the Board to meet without
      the presence of management and without the presence of members of the
      Board who are related to the Company's significant shareholder at the
      conclusion of each Board meeting.

14.   The Audit Committee is composed entirely of outside directors. The terms
      of reference for the Committee specifically define its responsibilities
      and include the oversight of management reporting on internal controls.
      The external auditors of the Company are invited to attend all meetings
      of the Committee, and Committee members are afforded the opportunity to
      communicate with the external auditors without the presence of
      management.

15.   The Company has a policy enabling an individual director, upon notice to
      the President and Chief Executive Officer and with the approval of the
      Corporate Governance Committee, to engage, at the Company's expense, an
      outside advisor.
