                         REPORT ON CORPORATE GOVERNANCE
 
GENERAL
 
     The Bylaws of The Toronto Stock Exchange and a Policy Statement of the
Montreal Exchange require that each listed company must provide annually a
description of the company's system of corporate governance with reference to
the guidelines contained in the report of The Toronto Stock Exchange Committee
on Corporate Governance in Canada (the "Guidelines") and, where the company's
system is different from the Guidelines an explanation of the differences must
be provided.
 
BOARD OF DIRECTORS
 
     The Board of Directors of the Corporation has assumed responsibility for
the stewardship of the Corporation, including responsibility for strategic
planning, identification of principal risks and the implementation of
appropriate systems to manage these risks, succession planning, including the
appointment, training and monitoring of senior management, the adoption of a
communications policy for the Corporation and for the integrity of the
Corporation's internal control and management information systems.
 
     The Board of Directors from time to time has examined its size and
concluded that a board comprised of eight to twelve members is appropriate. The
Board considers on an ongoing basis whether additional members should be added.
 
     The Board of Directors believes that the Board should be composed of a
majority of unrelated directors. During 1997 the Board of Directors was
comprised of ten members, six of whom the Corporation considered to be
unrelated. In April 1998 Felix Pardo's status changed from an unrelated director
to a related director upon his appointment as the Chief Operating Officer of the
Corporation. In May 1998 Howard L. Beck, an unrelated director, resigned. Nine
persons have been nominated for election as directors at the Meeting. The
Corporation considers six of the nominees to be unrelated.
 
     The Board is currently comprised of nine members. The Corporation considers
four of the directors to be unrelated directors as they are independent of
management and free from any interest and any business or other relationship
which could or could reasonably be perceived to materially interfere with the
director's ability to act with a view to the best interests of the Corporation.
The Corporation considers Allen Fracassi, Philip Fracassi and Felix Pardo as
related directors, given that they are all full time employees of the
Corporation. The Corporation considers Norman Foster a related director because
he was President of the Corporation's By-Products Recovery Group from February
1996 to July 1997 and President from November, 1981 to July, 1997 of Nortru,
Inc., a subsidiary of the Corporation. The Corporation considers Herman Turkstra
a related director because he is an associate of a law firm which provides legal
services to the Corporation. The Corporation considers each of Roy Cairns,
Derrick Rolfe, William E. Haynes and Robert L. Knauss as unrelated directors. In
this regard, the Corporation considered that: (i) Mr. Rolfe is Managing Director
of Environmental Research & Development Capital Corporation, a venture capital
company which
 
                                        7
<PAGE>   11
 
focuses on investments in environmental companies. The Corporation, along with
three institutional investors, each have a 25% interest in Environmental
Research & Development Capital Corporation. The Corporation does not believe
that this relationship could or could reasonably be perceived to materially
interfere with Mr. Rolfe's ability to act in the best interests of the
Corporation; (ii) Mr. Haynes is the Chairman, President and Chief Executive
Officer of Innovative Valve Technologies, Inc., a publicly traded company which
provides maintenance, repair and value-added distribution services for
industrial valves. The Corporation holds a 29.9% interest in Innovative Valve
Technologies, Inc. The Corporation does not believe that this relationship could
or could reasonably be perceived to materially interfere with Mr. Haynes'
ability to act in the best interests of the Corporation; (iii) neither Mr.
Cairns nor Mr. Knauss has been an officer or employee of the Corporation and has
no other material connection with the Corporation.
 
     In order to ensure that the Board of Directors can function independently
of management, the Board is chaired by Robert L. Knauss, an unrelated director.
In addition, the Corporation has established committees responsible for specific
areas which bear upon the overall performance of the Corporation. These
committees, except for the Health, Safety and Environmental Committee which is
comprised of two related directors and two unrelated directors and except for
the Executive Committee, are composed of a majority of unrelated directors. The
Board of Directors is considering the implementation of a system which would
enable an individual director to obtain outside advice at the expense of the
Corporation in appropriate circumstances.
 
     In accordance with the Guidelines, the Corporation provides an orientation
and education program for new members of the Board of Directors. The core
components of this program are meetings with senior operating executives to
obtain an understanding of the Corporation's business as well as visits to
significant operating facilities of the Corporation.
 
     During 1997, there were a total of nineteen Board of Directors meetings and
all directors attended at least 95 per cent of the meetings of the Board and the
committees of which they were members.
 
COMMITTEES
 
     The Corporation has an Executive Committee, an Audit Committee, a Health,
Safety and Environmental Committee, a Corporate Governance Committee and a
Compensation Committee.
 
     The Corporate Governance Committee is composed of Roy Cairns, Robert L.
Knauss, Derrick Rolfe and Herman Turkstra. The responsibilities of the Committee
include the consideration of the Corporation's corporate governance policies and
practises. In addition, the committee reviews candidates for election as
directors. The Committee met once during 1997.
 
     The Executive Committee is composed of Allen Fracassi, Philip Fracassi,
Felix Pardo and Herman Turkstra. The Executive Committee meets on an as needed
basis to consider matters, primarily of an operating nature. This committee did
not meet during 1997. The Audit Committee was comprised of Howard L. Beck, Felix
Pardo and Derrick Rolfe, until Mr. Beck's resignation as Chairman and Director
of the Corporation effective May 7, 1998. Mr. Beck was considered and Mr. Rolfe
is considered an unrelated director. The Audit Committee was comprised solely of
unrelated directors until the appointment of Felix Pardo as Chief Operating
Officer on April 1, 1998. The Board intends to establish an Audit Committee
comprised solely of unrelated directors immediately after the Meeting. The Audit
Committee meets at least quarterly to review the Corporation's financial
statements and is also responsible for approving the scope of the Corporation's
annual audit plan, reviewing the results thereof and considering issues relating
to the Corporation's internal accounting and audit control procedures. The Audit
Committee meets on a regular basis with the Corporation's auditors independent
of management to discuss and review specific issues as required. The Audit
Committee met six times during the year ended December 31, 1997. The Health,
Safety and Environmental Committee is comprised of Roy Cairns, Norman Foster,
Herman Turkstra and William E. Haynes, two of whom are unrelated directors. The
Health, Safety and Environmental Committee meets on a quarterly basis to review
the Corporation's compliance with its Health, Safety and Environmental policies
and with applicable laws and regulations. The Health, Safety and Environmental
Committee receives and reviews reports of the Corporation's internal health,
safety and environmental audit departments and from the Corporation's
independent external environmental auditor. The Health, Safety and Environmental
Committee
                                        8
<PAGE>   12
 
is also responsible for approving the scope of the Corporation's external
environmental audit and approving the structure and responsibilities of the
Corporation's internal environmental audit department. This committee met five
times during 1997. The Compensation Committee is comprised of Derrick Rolfe and
Roy Cairns both of whom are considered unrelated directors. The Compensation
Committee meets as required to consider the compensation of the executive
officers of the Corporation. The Compensation Committee also considers the
adequacy and form of compensation of directors to ensure that it reflects the
responsibilities and risks involved in being an effective director. This
committee met once during 1997.
 
     There is no specific mandate for the Board of Directors, since the Board
has plenary power. Any responsibility which is not delegated to senior
management or a Board committee remains with the full Board. The Board's
expectations of management include providing timely reports on the business and
affairs of the Corporation, preparing annual budgets and monitoring the
Corporation's performance as compared to such budgets and taking necessary steps
to accomplish strategic objectives established by the Board. The Board of
Directors reviews and approves the Corporation's annual operating budget.
Included in the budget are operating objectives which the Chief Executive
Officer is responsible for meeting. The Board also considers at its meetings and
provides direction to the Chief Executive Officer in regard to strategic
objectives of the Corporation.
 
SHAREHOLDER COMMUNICATION
 
     The Corporation has established procedures for communicating with its
shareholders to ensure that they receive timely disclosure of material
information relating to the Corporation.
 
     The Corporation believes that its corporate governance practices are
appropriate. The Board of Directors, through its Corporate Governance Committee,
will continue to monitor its corporate governance practices on an ongoing basis
and make such changes thereto as are necessary to ensure an effective corporate
governance system is in place.
 
COMPENSATION OF DIRECTORS
 
     Each director of the Corporation who is not a salaried officer or employee
of the Corporation is paid an annual fee of Cdn$25,000 and a fee of Cdn$1,000
per meeting (including committee meetings) attended, and each director, when
first appointed to the Board of Directors, receives a one time award of 20,000
options to acquire Shares of the Corporation. In addition, during 1997, a one
time grant of 20,000 options to acquire Shares was granted to each non-employee
Director. The options are granted at an exercise price equal to the closing
price of the Shares on The Toronto Stock Exchange on the last trading day
preceding the date of the grant and vest over a period of three years from the
date of the grant. For acting as Chairman of the Board of Directors during 1997,
Howard L. Beck was paid a fee of Cdn$150,000 during 1997. On May 7, 1998, Mr.
Beck resigned from the position of Chairman and Director of Philip.

                             EXECUTIVE COMPENSATION
 
REPORT ON EXECUTIVE COMPENSATION
 
     The Compensation Committee is responsible for the periodic review of the
Corporation's policies for attracting, retaining and motivating qualified
executive employees. In its review, the Compensation Committee considers
relevant independent compensation surveys and the compensation practices of
other North American companies. Based on its review, the Compensation Committee
makes recommendations to the Board of Directors of the Corporation regarding the
compensation of the Corporation's executive officers.
 
     The Compensation Committee believes that compensation practices should
motivate executive officers to maximize value for the Corporation's
shareholders. To achieve this objective, the Compensation Committee has
established compensation packages for the executive officers comprised of a base
salary and short and long term incentives. The short term incentive is based on
the award of annual cash bonuses which are dependent on the achievement of
financial, operational and corporate objectives and certain qualitative matters.
Long term incentives are tied to the appreciation in the value of the Shares and
take the form of options to acquire Shares.
 
     Base salaries of the executive officers are reviewed annually and are based
on an individual's expertise, skills, responsibilities, performance and
contribution to the achievement of the Corporation's objectives. Base salaries
are established at levels that are generally comparable to similar executive
positions in North American companies. In 1997 the Compensation Committee
increased the executive officers base salaries upon the recommendation of
independent compensation consultants retained by the Committee.
 
     Under the Corporation's 1997 short term incentive program, the President
and Chief Executive Officer is entitled to an annual bonus of up to 50% of his
base salary upon the achievement of target objectives, including earnings per
share objectives and up to 100% of his base salary at the discretion of the
Compensation Committee based upon the achievement of qualitative benchmarks. The
Chief Operating Officer is entitled to a bonus of up to 75% of the Chief
Executive Officer's bonus award for the achievement of target objectives and up
to 50% of his base salary at the discretion of the Compensation Committee based
upon the achievement of qualitative benchmarks. The other executive officers are
entitled to discretionary annual bonuses which are determined in part upon the
achievement of earnings per share objectives and in part upon the achievement of
qualitative benchmarks. As targeted earnings objectives were not achieved in
1997, no bonuses were earned with respect to the earnings based portion of the
Corporation's 1997 short term incentive program. The Compensation Committee
considered whether discretionary bonuses should be awarded but concluded that in
light of the Corporation's 1997 financial performance, no discretionary awards
should be made.
 
     To focus the attention of the executive officers on the long term interests
of the Corporation and its shareholders, the Corporation grants options at
market value to acquire its Shares. To encourage continued service, the
Corporation's practice has been to vest option grants over three years. Annual
option grants have been made to the executive officers of the Corporation based
upon their level of responsibility and compensation and contribution during the
year to the achievement of operational objectives.

EMPLOYMENT AGREEMENTS
 
     The Corporation has entered into employment agreements with each of the
Named Executive Officers. The agreements set forth the benefits to which a Named
Executive Officer would be entitled in the event of termination without cause
before or after an event which gives rise to a change of control of the
Corporation or in the event of a change in the executive's responsibilities,
title, authority or compensation after an event which gives rise to a change of
control of the Corporation. In the event of termination without cause prior to a
change of control, a Named Executive Officer would be entitled to a severance
payment equal to two times his base salary plus two times the annual average
bonus and cash value of benefits earned by the Named Executive Officer in the
previous two years. In the event of termination without cause after a change of
control or in the event of a change in the Named Executive Officer's
responsibilities, title, authority or compensation within two years of a change
in control, a Named Executive Officer would be entitled to a severance payment
equal to three times his base salary plus three times the annual average of the
bonus and cash value of benefits earned by the Named Executive Officer in the
previous two years. In addition, stock options granted to the Named Executive
Officer will fully vest on termination and will remain exercisable until the
expiry of the original term of such options.
 
DIRECTORS' AND OFFICERS' LIABILITY INSURANCE
 
     The Corporation provides insurance for the benefit of directors and
officers of the Corporation against liability incurred by, arising from or
against them for certain of their acts, errors or omissions. These policies
provide maximum coverage in any one policy year of an aggregate of $100,000,000
subject to a $500,000 deductible. In the last completed fiscal year the total
premium for directors' and officers' liability insurance was $571,850. The

            SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
     Section 16(a) of the Securities Exchange Act of 1934, and its rules and
regulations thereunder require the Corporation's executive officers and
directors, and persons who beneficially own more than 10% of a registered class
of the Corporation's equity securities, to file reports of ownership and changes
of ownership with the Securities and Exchange Commission. Copies of those
reports are to be furnished to the Corporation. Based solely on its review of
copies of the reports received by it, or written representations from certain
reporting persons, the Corporation believes that during 1997 all such filing
requirements were satisfied on a timely basis.
 
                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     In connection with the December 1993 acquisition of Nortru, Inc. ("Nortru")
from Norman Foster, a director of the Corporation, the Corporation guaranteed a
$5,950,000 note payable by a wholly-owned subsidiary of the Corporation to Mr.
Foster. The note, which was unsecured, bore interest at U.S. prime plus 2% and
was payable in equal monthly installments of $165,000 plus interest maturing on
May 20, 1997. The outstanding balance of the note was paid in full by the
Corporation on May 21, 1997. In addition, in December, 1993, the Corporation
entered into a non-competition and retention agreement with Mr. Foster, pursuant
to which the Corporation agreed to pay Mr. Foster an aggregate of $7 million in
consideration for certain non-compete and employment covenants from Mr. Foster.
One payment of $1.4 million due under this agreement was paid in January, 1997,
another payment of 1.4 million was paid in January, 1998 and the final payment
under this agreement is due on December 31, 1998. During 1997, the Corporation
paid $323,520 in rental payments to Mr. Foster or entities which he controls or
has an ownership interest for properties utilized by the Corporation in the
operation of its business.
 
     In 1997, a wholly-owned subsidiary of the Corporation purchased an interest
in certain real property and associated royalty rights adjacent to its Taro
landfill, located in Stoney Creek, Ontario for a purchase price of $5.08 million
from AIC Holdings Inc., a Corporation in which Roy Cairns, a director of the
Corporation, owns a part interest.
 
     During 1997, the Corporation paid approximately $2.4 million to Cole
Carriers Corp. ("Coles"), a commercial trucking Corporation controlled by Philip
Fracassi and Allen Fracassi, officers and directors of the Corporation, for
truck transportation services rendered by Coles to the Corporation.
 
     The law firm of Turkstra, Mazza, Associates, of which Herman Turkstra is an
associate, provided services to the Corporation in 1997. Fees paid to members of
the firm in 1997 totalled Cdn$570,212.
 
     As at May 15, 1998, the aggregate amount of indebtedness due to the
Corporation from all current or former officers, directors and employees was
$515,000, consisting of the outstanding balance of a loan made to Allen
Fracassi, the President and Chief Executive Officer of the Corporation, for the
purpose of purchasing a home. The loan is unsecured, non-interest bearing and
payable on demand.

Meeting.
 
     Messrs. Deloitte & Touche expect to have a representative at the Meeting
who will have the opportunity to make a statement to the Meeting if he desires
to do so and who will be available to respond to appropriate questions.
 
                APPROVAL OF AMENDMENT TO SHAREHOLDER RIGHTS PLAN
 
     At the Meeting, shareholders will be asked to consider and if deemed
advisable, vote to ratify, confirm and approve the amended and restated
Shareholder Rights Plan (the "Rights Agreement") approved by the Board of
Directors of the Corporation as of May 15, 1998. The primary amendment to the
Rights Agreement is the extension of its term from June 30, 1998 to June 30,
2001.
 
     The Rights Agreement was originally adopted by the Corporation on April 11,
1995, amended and restated on May 19, 1995 and confirmed by the shareholders of
the Corporation on May 27, 1995.
 
     The full text of the Rights Agreement is set forth in Exhibit "A" hereto.
Initially capitalized terms used below without express definition have the
meanings ascribed thereto in the Rights Agreement.
 
BACKGROUND TO THE ADOPTION OF THE AMENDED AND RESTATED RIGHTS AGREEMENT
 
     The Rights Agreement was originally adopted to ensure that, in the event of
a Take-over Bid for Voting Shares of the Corporation, all shareholders would
receive full and fair value for their shares and would not be subject to abusive
or coercive take-over strategies, and that the Board of Directors, on behalf of
the Corporation and all of its shareholders, would have the time and opportunity
to evaluate the bid and its effects,
 
                                       15
<PAGE>   19
 
to seek out alternative bidders and to explore, develop and evaluate other ways
of maximizing shareholder value.
 
     At the time that the Rights Agreement was initially implemented, the Board
of Directors was of the view that the current legislative framework in Canada
and the United States did not adequately protect the rights of shareholders
during take-over bids. Specifically, the Board of Directors was concerned that
the minimum time periods for take-over bids specified under Canadian and United
States law might not provide an opportunity for shareholders and the Board of
Directors to properly assess the initiating bid and negotiate with the bidder,
for shareholders to assess the merits of competing bids and for the Board of
Directors to seek out or otherwise allow competing bidders to emerge or develop
other methods of maximizing shareholder value. In addition, the Board of
Directors was concerned that without the protection of a rights plan,
shareholders may feel compelled to tender to a take-over bid which they consider
to be inadequate and not to represent full and fair value because, in failing to
do so, the shareholder might be left with illiquid or minority discounted voting
securities in the Corporation. Finally, the Board of Directors was concerned
that, as a result of differing securities laws in Canada and the United States,
shareholders might be vulnerable to discriminatory acquisition tactics or that
an offeror might otherwise be able to obtain control of the Corporation without
paying full value, without obtaining shareholder approval and without treating
all shareholders equally.
 
     The current legislative framework governing take-over bids is substantially
the same regime that was applicable at the time the Rights Agreement was
originally adopted. Accordingly, the Board of Directors continues to believe
that the Rights Agreement is a valuable tool that can be utilized in the face of
an unsolicited take-over bid to assist shareholders in responding to the bid and
address the situations described above.
 
     In settling on the terms and conditions of the Rights Agreement, the Board
of Directors not only considered the current legislative framework in Canada and
the United States, but also the developments in shareholder rights plans over
the last three years and recent experience in the context of actual take-over
bids.
 
     The amendment and restatement of the Rights Agreement was not adopted in
response to, or in anticipation of, any acquisition proposal, nor is it intended
to prevent a take-over bid from being made for the Corporation or to secure
continuance of management or the directors in office.
 
SUMMARY OF THE TERMS AND OPERATION OF THE RIGHTS AGREEMENT
 
     The following is a summary of the terms of the Rights Agreement, which is
qualified in its entirety by reference to the text of such agreement.
 
GENERAL
 
     In general terms, if a person (an "Acquiring Person") acquires twenty
percent (20%) or more of the Voting Shares of the Corporation other than by way
of a Permitted Bid or a Competing Bid (each as discussed below), holders of
Rights other than the Acquiring Person may acquire Shares of the Corporation at
a significant discount to the then prevailing market price. Accordingly, in such
a case, the Rights will cause substantial dilution to an Acquiring Person that
becomes an Acquiring Person other than through a Permitted Bid or a Competing
Bid.
 
TRADING OF RIGHTS
 
     Rights issued prior to the Separation Time are not exercisable and are
evidenced by the Share certificate in respect of which the Right was granted. In
addition, until the Separation Time, Rights will be transferable only together
with, and will be transferred by, a transfer of the associated Shares. Until the
Separation Time or earlier redemption or expiration of the Rights, new share
certificates issued upon the transfer of existing Shares or the issuance of
additional Shares, including additional Shares issued upon the conversion of
Debentures, will bear a legend incorporating the Rights Agreement by reference.
 
                                       16
<PAGE>   20
 
SEPARATION TIME
 
     After the Separation Time, the Rights will separate and trade separately
from the Shares. Following the Separation Time, separate certificates evidencing
the Rights ("Rights Certificates") will be mailed to holders of record of Shares
as of the close of business on the Separation Time, or, in the case of
Debentures converted into Shares after the Separation Time and prior to the
close of business on the 15th day following notice of the Stock Acquisition Date
having been sent by the Corporation to the holders of Debentures, promptly after
such conversions, to the holders so converting, and each separate Rights
Certificate alone will evidence the Rights.
 
     The "Separation Time" is the close of business on the tenth trading day
following the earlier of (i) the date (the "Stock Acquisition Date") of the
first public announcement made by the Corporation or an Acquiring Person that a
person has become an Acquiring Person, and (ii) the date of the commencement of,
or first public announcement of, the intent of any person (other than the
Corporation or any subsidiary of the Corporation) to commence a Take-over Bid
(other than a Permitted Bid or Competing Bid).
 
     If any Take-over Bid triggering the Separation Time expires or is
cancelled, terminated or otherwise withdrawn prior to the Separation Time or if
the Board of Directors determines to waive application of the Rights Agreement
to any such Take-over Bid, then such bid shall be deemed, for the purposes of
determining the Separation Time, never to have been made.
 
EXERCISE PRICE OF RIGHTS
 
     After the Separation Time and prior to the occurrence of a Flip-in Event,
each Right will entitle the registered holder thereof to purchase from the
Corporation one Share at an Exercise Price of $75.00 per Share, subject to
certain anti-dilution adjustments as set out in the Rights Agreement and
summarized below under "Protection Against Dilution".
 
PROTECTION AGAINST DILUTION
 
     The Exercise Price, the number and nature of securities which may be
purchased upon the exercise of the Rights and the number of Rights outstanding
are subject to adjustment from time to time to prevent dilution upon certain
changes to the share capital of the Corporation. Under the Rights Agreement,
anti-dilution adjustment provisions are applicable (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Shares,
(ii) upon the grant to holders of Shares of certain rights, options or warrants
to subscribe for Shares or convertible securities, or (iii) upon distribution to
holders of Shares of evidence of indebtedness, cash (excluding regular periodic
cash dividends or a regular periodic cash dividend paid in Shares), assets, or
rights, options or warrants (other than those referred to in clause (ii) above).
The adjustment provisions are designed to ensure that the number of Shares which
may be purchased upon the exercise of Rights and payment of the Exercise Price
remains proportionally constant and are not subject to any dilution which may
result from changes to the share capital of the Corporation.
 
FLIP-IN EVENT
 
     A "Flip-in Event" is triggered in the event that a transaction occurs
pursuant to which a person becomes an Acquiring Person. Upon the occurrence of a
Flip-in Event, the Corporation must take such action as shall be necessary to
ensure that each Right (except for Rights Beneficially Owned by the persons
specified below) shall thereafter constitute the right to purchase from the
Corporation upon exercise thereof in accordance with the terms of the Rights
Agreement that number of Shares of the Corporation having an aggregate Market
Price on the date of the consummation or occurrence of such Flip-in Event equal
to twice the Exercise Price for an amount in cash equal to the Exercise Price.
 
     The Rights Agreement provides that Rights that are Beneficially Owned by
(i) an Acquiring Person or any Affiliate or Associate of an Acquiring Person or
any Person acting jointly or in concert with an Acquiring Person or any
Affiliate or Associate of such Acquiring Person or any Affiliate or Associate of
such Person so acting jointly or in concert, or (ii) a transferee or other
successor in title of Rights of an Acquiring Person (or an Affiliate or
Associate of an Acquiring Person) or of any person acting jointly or in concert
with an
 
                                       17
<PAGE>   21
\ 
Acquiring Person or any Associate or Affiliates of an Acquiring Person who
becomes a transferee or successor in title concurrently with or subsequent to
the Acquiring Person becoming such, shall become null and void without any
further action and any holder of such Rights (including transferees or
successors in title) shall not have any rights whatsoever to exercise such
Rights under any provision of the Rights Agreement.
 
ACQUIRING PERSON
 
     An Acquiring Person is a Person who Beneficially Owns twenty percent (20%)
or more of the Voting Shares of the Corporation. The Rights Agreement provides
certain exemptions from this classification; however, including where a Person
becomes the Beneficial Owner of twenty percent (20%) or more of the outstanding
Voting Shares of the Corporation as a result of a Corporate Acquisition,
Permitted Bid Acquisition, Corporate Distribution, Exempt Acquisition or a
Convertible Security Acquisition; provided that such Person will subsequently
become an Acquiring Person upon becoming the Beneficial Owner of an additional
one percent (1%) of the currently outstanding Voting Shares of the Corporation
(other than pursuant to a further exempt transaction).
 
PERMITTED BIDS AND COMPETING BIDS
 
     A "Permitted Bid" is a Take-over Bid made by take-over bid circular in
compliance with the following additional provisions:
 
     (1)  The bid must be made to all holders of record of Voting Shares (for
          all or any portion of the Voting Shares);
 
     (2)  The bid must be open for a minimum of 60 days following the date of
          the bid and no shares may be taken up prior to such time;
 
     (3)  Take-up and payment for shares may not occur unless the bid is
          accepted by more than fifty percent (50%) of the then outstanding
          Voting Shares held by Independent Shareholders;
 
     (4)  Shares may be deposited into or withdrawn from the bid at any time
          prior to the take-up date; and
 
     (5)  If the bid is accepted by the requisite percentage specified in (3)
          above, the bidder must extend the bid for a period of 10 Business Days
          to allow other shareholders to tender into the bid should they so wish
          and must make a public announcement to such effect.
 
     A "Competing Bid" is a Take-over Bid that satisfies all the criteria of a
Permitted Bid except that (i) since it is made after a Permitted Bid has been
made, the minimum deposit period and the time period for the take-up of and
payment for shares tendered under a Competing Bid is not 60 days, but is instead
the greater of 21 days and the earliest date for take-up and payment of shares
under any other Permitted Bid then in existence.
 
     Neither a Permitted Bid nor a Competing Bid need be approved by the Board
of Directors and may be taken directly to the shareholders of the Corporation.
Acquisitions of Voting Shares made pursuant to a Permitted Bid or a Competing
Bid do not give rise to a Flip-in-Event.
 
REDEMPTION AND WAIVER
 
     The Board of Directors may, at its option, at any time prior to the
occurrence of a Flip-in Event, elect to redeem all but not less than all of the
Rights at a redemption price of $0.0001 per Right (the "Redemption Price"),
appropriately adjusted in the event that an event analogous to those described
above under "Protection Against Dilution" shall have occurred. Rights will be
deemed to automatically be redeemed at the Redemption Price where a person
acquires Voting Shares (other than the Offeror's Securities) pursuant to a
Permitted Bid, a Competing Bid or an Exempt Acquisition. If the Board of
Directors elects or is deemed to have elected to redeem the rights, the right to
exercise the Rights will terminate and each Right will after redemption be null
and void and the only right thereafter of the holders of Rights shall be to
receive the Redemption Price.
 
                                       18
<PAGE>   22
 
     Under the Rights Agreement, the Board of Directors has the discretion to
waive the application of the Rights Agreement to a Take-over Bid made by way of
Take-over Bid circular to all holders of Voting Shares of the Corporation;
provided that the application of the Rights Agreement will then be automatically
waived for every other Take-over Bid made by way of Take-over Bid circular to
all holders of Voting Shares of the Corporation.
 
     The Board of Directors of the Corporation may also, prior to the close of
business on the tenth day after a Stock Acquisition Date, waive or agree to
waive the application of the Rights Agreement to an inadvertent Flip-in Event,
provided that: (i) the Board of Directors determines that the person became an
Acquiring Person by inadvertence and without any intention to become, or
knowledge that it would become, an Acquiring Person; and (ii) such acquiring
Person has reduced its Beneficial Ownership of Shares such that at the time of
the granting of a waiver such person is no longer an Acquiring Person or has
entered into an agreement with the Corporation to do so within 30 days.
 
     Any other waiver of the application of the Rights Agreement requires the
prior consent of the holders of Voting Shares.
 
AMENDMENTS TO RIGHTS AGREEMENT
 
     The Rights Agreement provides that the right of the Corporation to make
changes without the approval of holders of Voting Shares, or, after the
Separation Time, Rights, is limited to amendments to correct any clerical or
typographical errors.
 
     The Corporation may also make amendments, effective upon adoption, required
to maintain the validity and effectiveness of the Rights Agreement as a result
of any change in any applicable laws or regulatory requirements. However, any
such amendments will cease to be effective unless approved by the holders of
Voting Shares or, after the Separation Time, Rights, at or immediately following
the next meeting of shareholders of the Corporation.
 
     Any other changes (whether or not they materially adversely affect the
holders of Rights) may be made by the Corporation only with the prior consent of
the holders of Voting Shares, or, after the Separation Time, Rights.
 
REGULATORY APPROVALS
 
     Certain obligations of the Corporation, actions and events contemplated by
the Rights Agreement, and any amendments to the Rights Agreement, are subject to
the prior approval of government and regulatory authorities, including
securities regulatory authorities and stock exchanges.
 
PRINCIPAL AMENDMENTS
 
     The primary rationale for the amendment and restatement of the Rights
Agreement is to extend its Expiration Time from June 30, 1998 to June 30, 2001.
Concurrently with such extension; however, certain technical and other
amendments were made to the Rights Agreement to ensure that it remains
consistent with the current generation of Canadian rights plans and that it
adequately addresses the concerns of institutional investors as expressed by
industry commentators. Such amendments consist primarily of the following:
 
     1.    The definition of "Beneficial Ownership" was amended to include
        exemptions for "permitted lock-up agreements" and persons who are
        registered holders of securities as a result of carrying on the business
        of, or acting as the nominee of, a securities depository.
 
     2.    The "Exempt Acquisition" exemption from the definition of "Acquiring
        Person" which, among other things, permits acquisitions of securities by
        means of a private placement was redrafted to clearly provide that the
        exemption is only available where (x) all necessary stock exchange
        approvals have been obtained and the private placement complies with the
        terms and conditions of such approvals, and (y) the purchaser does not
        become the Beneficial Owner of more than 25% of the Voting Shares
        outstanding immediately prior to the private placement.
 
                                       19
<PAGE>   23
 
     3.    A "Convertible Security Acquisition" exemption from the definition of
        "Acquiring Person" was added to ensure that an acquisition of Voting
        Shares received upon the exercise of Convertible Securities received by
        a Person pursuant to a Permitted Bid Acquisition, Exempt Acquisition or
        a Corporate Distribution will not trigger the Rights Agreement.
 
     4.    The definition of "Competing Bid" was amended to remove the
        requirement that a Competing Bid be made for all Voting Shares of the
        Corporation if the Permitted Bid was made for all Voting Shares of the
        Corporation.
 
     5.    Other provisions of the Rights Agreement were redrafted in a
        non-material fashion to facilitate the amendment and restatement of the
        agreement, to harmonize certain provisions of the Rights Agreement as a
        result of the changes listed above and to ensure that the Rights
        Agreement conforms to the current generation of rights plans in Canada.
 
RESOLUTION
 
     The text of the resolution reconfirming the Rights Agreement (the "Rights
Agreement Resolution") is as follows:
 
     RESOLVED THAT the amendments to the Corporation's Shareholder Rights Plan
described in the Corporation's May 15, 1998 Proxy Statement and the amended and
restated shareholder rights plan agreement effective June 25, 1998 annexed to
the Corporation's May 15, 1998 Proxy Statement as Exhibit "A" are hereby
approved by the shareholders of the Corporation.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS
 
     THE BOARD OF DIRECTORS HAS DETERMINED THAT THE RIGHTS AGREEMENT CONTINUES
TO BE IN THE BEST INTERESTS OF THE CORPORATION AND ITS SHAREHOLDERS AND
RECOMMENDS THAT SHAREHOLDERS VOTE IN FAVOUR OF THE RIGHTS AGREEMENT RESOLUTION.
 
     IN THE ABSENCE OF A CONTRARY INSTRUCTION, THE PERSONS NAMED IN THE ENCLOSED
FORM OF PROXY INTEND TO VOTE IN FAVOUR OF THE PASSING OF THE RIGHTS AGREEMENT
RESOLUTION. Passage of the Rights Agreement Resolution requires approval by a
majority of the votes cast on the matter at the Meeting. According to the terms
of the Rights Agreement, any shareholder who, at the time of the vote, is an
Offeror pursuant to a Take-over Bid that is not a Permitted Bid or a Competing
Permitted Bid will not be eligible to participate in the vote.

                            SHAREHOLDER RIGHTS PLAN
 
     THIS AGREEMENT amended and restated effective June 25, 1998 between Philip
Services Corp. (formerly, Philip Environmental Inc.) (the "Corporation"), a

Montreal Trust Company of Canada, a trust company incorporated under the laws of
Canada, as Rights Agent (the "Rights Agent", which term shall include any
successor Rights Agent hereunder);
 
     WITNESSES THAT:
 
     WHEREAS the Board of Directors has determined that it is advisable and in
the best interests of the Corporation to adopt and maintain a shareholder rights
plan (the "Rights Plan");
 
     AND WHEREAS the Corporation and the Rights Agent entered into a shareholder
rights plan (the "Original Agreement") dated as of April 11, 1995 and amended
and restated as of May 19, 1995 and wish to amend and restate the Original
Agreement by entering into this Agreement;
 
     AND WHEREAS in order to implement the adoption of the Rights Plan the Board
of Directors has:
 
     (a)  authorized the issuance of one Right effective the Record Time in
        respect of each Common Share outstanding at the Record Time; and
 
     (b)  authorized the issuance of one Right in respect of each Common Share
        issued after the Record Time and prior to the earlier of the Separation
        Time and the Expiration Time, and with respect to the Debentures,
        authorized the issuance of one Right in respect of each Common Share
        issued upon the conversion of Debentures after the Separation Time and
        prior to the close of business on the fifteenth (15th) day following
        notice of the Stock Acquisition Date having been sent by the Corporation
        to the holders of Debentures;
 
     AND WHEREAS each Right entitles the holder thereof, after the Separation
Time, to purchase securities of the Corporation pursuant to the terms and
subject to the conditions set forth herein;
 
     AND WHEREAS the Corporation has appointed the Rights Agent to act on behalf
of the Corporation in connection with the issuance, transfer, exchange and
replacement of Rights Certificates, the exercise of Rights, and other matters
referred to herein;
 
     NOW THEREFORE in consideration of the foregoing premises and the respective
covenants and agreements set forth herein the parties hereby agree as follows:
 
                          ARTICLE 1 -- INTERPRETATION

<PAGE>   28

             of the Corporation alone or by acting jointly or in concert with
             any other Person (the first date of public announcement (which, for

             twenty percent (20%) or more of the outstanding Voting Shares
             determined as at the Record Time; provided, however, that this
             exception shall not be, and shall cease to be, applicable to a
             Grandfathered Person in the event that such Grandfathered Person
             shall, after the Record Time, become the Beneficial Owner of any
             additional Voting Shares that increase its Beneficial Ownership of
             Voting Shares by more than one percent (1%) of the number of Voting
             Shares outstanding as at the Record Time, other than as may be
             acquired pursuant to Corporate Acquisitions, Permitted Bid
             Acquisitions, Corporate Distributions, Exempt Acquisitions or
             Convertible Securities Acquisitions.

        intermediaries, controls, or is controlled by, or is under common

     (g)  a Person shall be deemed the "BENEFICIAL OWNER", and to have
        "BENEFICIAL OWNERSHIP" of, and to "BENEFICIALLY OWN":
 
        (i)   any securities of which such Person or any Affiliate or Associate
             of such Person is the owner in law or equity;
 
        (ii)  any securities as to which such Person or any of such Person's
             Affiliates or Associates has the right to acquire (A) upon the

          however, that if on any such date the securities are not traded in the
          over-the-counter market, the closing price per share of such
          securities on such date shall mean the fair value per share of such
          securities on such date as determined in good faith by a nationally or
          internationally recognized investment dealer or investment banker. The

          determined in respect of any day forming part of the twenty (20)
          consecutive trading day period in United States dollars, such amount

          Equivalent thereof. Notwithstanding the foregoing, where the Board of
          Directors is satisfied that the Market Price of securities as
          determined herein was affected by an anticipated or actual Take-over
          Bid or by improper manipulation, the Board of Directors may, acting in
          good faith, determine the Market Price of securities, such
          determination to be based on a finding as to the price of which a
          holder of securities of that class could reasonably have expected to

     certain Rights as set forth in a Shareholder Rights Plan Agreement, dated
     as of April 11, 1995, as amended and restated from time to time (the

     Montreal Trust Company of Canada, as rights agent (the "Rights Agent"), the
     terms of which are hereby incorporated herein by reference and a copy of
     which is on file at the principal executive office of the Corporation.
     Under certain circumstances, as set forth in the Rights Plan, such Rights
     may be amended or redeemed, may expire, may become null and void (if, in
     certain cases, they are issued to or "Beneficially Owned" by any Person who
     is, was or becomes an "Acquiring Person", as such terms are defined in the

<PAGE>   38
 
Common Shares are subject to adjustment as set forth below and are subject to
Subsection 3.1(a)). Notwithstanding any other provision of this Agreement, any
Rights held by the Corporation and any of its Subsidiaries shall be void.
 
     (b) RIGHTS NOT EXERCISABLE UNTIL SEPARATION TIME. Until the Separation
Time, (A) the Rights shall not be exercisable and no Right may be exercised, and

the close of business on the fifteenth (15th) day following notice of the Stock

furnish copies of such records to the Rights Agent for this purpose), (A) a

regulation made pursuant thereto or with any rule or regulation of any

accompanied by payment in cash, by certified cheque, banker's draft or money
order payable to the order of the Corporation, of a sum equal to the Exercise
Price multiplied by the number of Rights being exercised and a sum sufficient to
cover any transfer tax or charge which may be payable in respect of any transfer
involved in the transfer or delivery of Rights Certificates or the issuance or
delivery of certificates for Common Shares in a name other than that of the
holder of the Rights being exercised, all of the above to be received before the
Expiration Time by the Rights Agent at its principal office in any of the cities

        Rights.
 
     (f) PARTIAL EXERCISE OF RIGHTS. In case the holder of any Rights shall

Certificate, a new Rights Certificate evidencing the Rights remaining
unexercised will be issued by the Rights Agent to such holder or to such
holder's duly authorized assigns.

will:

     (iv) cause to be reserved and kept available out of its authorized and
        unissued Common Shares, the number of Common Shares that, as provided in
        this Agreement, will from time to time be sufficient to permit the
        exercise in full of all outstanding Rights;
 
     (v)  pay when due and payable any and all Canadian and, if applicable,
        United States, federal, provincial and state transfer taxes and charges
        (not including any income or capital taxes of the holder or exercising
        holder or any liability of the Corporation to withhold tax) which may be
        payable in respect of the original issuance or delivery of the Rights
        Certificates, provided that the Corporation shall not be required to pay
        any transfer tax or charge which may be payable in respect of any
        transfer involved in the transfer or delivery of Rights Certificates or
        the issuance or delivery of certificates for shares or other securities
        in a name other than that of the registered holder of the Rights being
        transferred or exercised; and
 
     (vi) after the Separation Time, except as permitted by Sections 5.1 or 5.4
        hereof, not take (or permit any Subsidiary to take) any action if at the
        time such action is taken it is reasonably foreseeable that such action
        will diminish substantially or otherwise eliminate the benefits intended
        to be afforded by the Rights.
 
2.3 ADJUSTMENTS TO EXERCISE PRICE; NUMBER OF RIGHTS
 
     The Exercise Price, the number and kind of Common Shares or other
securities subject to purchase upon exercise of each Right and the number of
Rights outstanding are subject to adjustment from time to time as provided in
this Section 2.3.
 
                                       13
<PAGE>   40
 
     (a) ADJUSTMENT TO EXERCISE PRICE UPON CHANGES TO SHARE CAPITAL. In the
event the Corporation shall at any time after the Record Time:
 
     (A) declare or pay a dividend on the Common Shares payable in Common Shares
        (or other securities exchangeable for or convertible into or giving a
        right to acquire Common Shares or other securities) other than the issue
        of Common Shares or such exchangeable or convertible securities to
        holders of Common Shares in lieu of but not in an amount which exceeds
        the value of regular periodic cash dividends;
 
     (B)  subdivide or change the outstanding Common Shares into a greater
        number of Common Shares;
 
     (C) combine or change the outstanding Common Shares into a smaller number
        of Common Shares or;
 
     (D) issue any Common Shares (or other securities exchangeable for or
        convertible into or giving a right to acquire Common Shares or other
        securities) in respect of, in lieu of or in exchange for existing Common
        Shares, except as otherwise provided in this Section 2.3;
 
the Exercise Price in effect at the time of the record date for such dividend or
of the effective date of such subdivision, combination or reclassification, and
the number and kind of Common Shares, or other securities, as the case may be,
issuable on such date, shall be proportionately adjusted so that the holder of
any Right exercised after such time shall be entitled to receive, upon payment
of the Exercise Price then in effect, the aggregate number and kind of Common
Shares or other securities, as the case may be, which, if such Right had been
exercised immediately prior to such date and at a time when the Common Share
transfer books of the Corporation were open, such holder would have owned upon
such exercise and been entitled to receive by virtue of such dividend,
subdivision, combination or reclassification. If an event occurs which would
require an adjustment under both this Section 2.3 and Section 3.1 hereof, the
adjustment provided for in this Section 2.3 shall be in addition to, and shall
be made prior to, any adjustment required pursuant to Section 3.1 hereof.
 
     (b) ADJUSTMENT TO EXERCISE PRICE UPON ISSUE OF RIGHTS, OPTIONS AND
WARRANTS. In case the Corporation shall at any time after the Record Time fix a
record date for the issuance of rights, options or warrants to all holders of
Common Shares entitling them (for a period expiring within forty-five (45)
calendar days after such record date) to subscribe for or purchase Common Shares
(or shares having the same rights, privileges and preferences as Common Shares
("equivalent common shares")) or securities convertible into or exchangeable for
or carrying a right to purchase Common Shares or equivalent common shares at a
price per Common Share or per equivalent common share (or having a conversion
price or exchange price or exercise price per share, if a security convertible
into or exchangeable for or carrying a right to purchase Common Shares or
equivalent common shares) less than ninety percent (90%) of the Market Price per
Common Share on such record date, the Exercise Price to be in effect after such
record date shall be determined by multiplying the Exercise Price in effect
immediately prior to such record date by a fraction, the numerator of which
shall be the number of Common Shares outstanding on such record date, plus the
number of Common Shares that the aggregate offering price of the total number of
Common Shares and/or equivalent common shares so to be offered (and/or the
aggregate initial conversion, exchange or exercise price of the convertible or
exchangeable securities or rights so to be offered, including the price required
to be paid to purchase such convertible or exchangeable securities or rights so
to be offered) would purchase at such Market Price per Common Share, and the
denominator of which shall be the number of Common Shares outstanding on such
record date, plus the number of additional Common Shares and/or equivalent
common shares to be offered for subscription or purchase (or into which the
convertible or exchangeable securities are initially convertible, exchangeable
or exercisable). In case such subscription price may be paid by delivery of
consideration, part or all of which may be in a form other than cash, the value
of such consideration shall be as determined in good faith by the Board of
Directors, whose determination shall be described in a certificate filed with
the Rights Agent and shall be binding on the Rights Agent and the holders of the
Rights. Such adjustment shall be made successively whenever such a record date
is fixed, and in the event that such rights or warrants are not so issued, the
Exercise Price shall be adjusted to be the Exercise Price which would then be in
effect if such record date had not been fixed.
 
                                       14
<PAGE>   41
 
     For purposes of this Agreement, the granting of the right to purchase
Common Shares (or equivalent common shares) (whether from treasury shares or
otherwise) pursuant to any dividend or interest reinvestment plan and/or any
Common Share purchase plan providing for the reinvestment of dividends or
interest payable on securities of the Corporation and/or the investment of
periodic optional payments and/or employee benefit, stock option or similar
plans (so long as such right to purchase is in no case evidenced by the delivery
of rights or warrants) shall not be deemed to constitute an issue of rights,
options or warrants by the Corporation; provided, however, that, in the case of
any dividend or interest reinvestment plan, the right to purchase Common Shares
(or equivalent common shares) is at a price per share of not less than ninety
percent (90%) of the current market price per share (determined as provided in
such plans) of the Common Shares.
 
     (c) ADJUSTMENT TO EXERCISE PRICE UPON CORPORATE DISTRIBUTIONS. In case the
Corporation shall at anytime after the Record Time fix a record date for a
distribution to all holders of Common Shares (including any such distribution
made in connection with a merger, amalgamation, arrangement, plan, compromise or
reorganization in which the Corporation is the continuing or successor
corporation) of evidences of indebtedness, cash (other than a regular periodic
cash dividend or a regular periodic cash dividend paid in Common Shares, but
including any dividend payable in securities other than Common Shares), assets
or subscription rights, options or warrants (excluding those referred to in
Subsection 2.3(b) above), the Exercise Price to be in effect after such record
date shall be determined by multiplying the Exercise Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be the
Market Price per Common Share on such record date, less the fair market value
(as determined in good faith by the Board of Directors, whose determination
shall be described in a statement filed with the Rights Agent) of the portion of
the cash, assets or evidences of indebtedness so to be distributed or of such
subscription rights, options or warrants applicable to a Common Share and the
denominator of which shall be such Market Price per Common Share. Such
adjustments shall be made successively whenever such a record date is fixed, and
in the event that such distribution is not so made, the Exercise Price shall be
adjusted to be the Exercise Price which would have been in effect if such record
date had not been fixed.
 
     (d) DE MINIMIS THRESHOLD FOR ADJUSTMENT TO EXERCISE PRICE. Notwithstanding
anything herein to the contrary, no adjustment in the Exercise Price shall be
required unless such adjustment would require an increase or decrease of at
least one percent (1%) in the Exercise Price; provided, however, that any
adjustments which by reason of this Subsection 2.3(d) are not required to be
made shall be carried forward and taken into account in any subsequent
adjustment. All calculations under this Section 2.3 shall be made to the nearest
cent or to the nearest one-hundredth of a Common Share or other share, as the
case may be. Notwithstanding the first sentence of this Subsection 2.3(d), any
adjustment required by this Section 2.3 shall be made no later than the earlier
of (A) three (3) years from the date of the transaction which mandates such
adjustment or (B) the Expiration Time.
 
     (e) CORPORATION MAY PROVIDE FOR ALTERNATE MEANS OF ADJUSTMENT. Subject to
the prior consent of the holders of Voting Shares or Rights obtained as set
forth in Subsections 5.4(b) or 5.4(c) hereof, as applicable, in the event the
Corporation shall at any time after the Record Time issue any shares of capital
stock (other than Common Shares), or rights or warrants to subscribe for or
purchase any such capital stock, or securities convertible into or exchangeable
for any such capital stock, in a transaction referred to in Clauses 2.3(a)(A) or
2.3(a)(D) or Subsections 2.3(b) or 2.3(c) above, if the Board of Directors
acting in good faith determines that the adjustments contemplated by Subsections
2.3(a), (b) and (c) above in connection with such transaction will not
appropriately protect the interests of the holders of Rights, the Corporation
shall be entitled to determine what other adjustments to the Exercise Price,
number of Rights and/or securities purchasable upon exercise of Rights would be
appropriate and, notwithstanding Subsections 2.3(a), (b) and (c) above, such
adjustments, rather than the adjustments contemplated by Subsections 2.3(a), (b)
and (c) above, shall be made. The Corporation and the Rights Agent shall amend
this Agreement as appropriate to provide for such adjustments.
 
     (f) ADJUSTMENT TO RIGHTS EXERCISABLE INTO SHARES OTHER THAN COMMON SHARES.
If as a result of an adjustment made pursuant to Section 3.1 hereof, the holder
of any Right thereafter exercised shall become entitled to receive any shares
other than Common Shares, thereafter the number of such other shares so
 
                                       15
<PAGE>   42
 
receivable upon exercise of any Right and the Exercise Price thereof shall be
subject to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions with respect to the Common Shares
contained in Subsections 2.3(a), (b), (c), (d), (e), (g), (h), (i), (j), (k) and
(l) above and below, as the case may be, and the provisions of this Agreement
with respect to the Common Shares shall apply on like terms to any such other
shares.
 
     (g) RIGHTS TO EVIDENCE RIGHT TO PURCHASE COMMON SHARES AT ADJUSTED EXERCISE
PRICE. Each Right originally issued by the Corporation subsequent to any
adjustment made to the Exercise Price hereunder shall evidence the right to
purchase, at the adjusted Exercise Price, the number of Common Shares
purchasable from time to time hereunder upon exercise of such Right, all subject
to further adjustment as provided herein.
 
     (h) ADJUSTMENT TO NUMBER OF COMMON SHARES PURCHASABLE UPON ADJUSTMENT TO
EXERCISE PRICE. Unless the Corporation shall have exercised its election as
provided in Subsection 2.3(i) below, upon each adjustment of the Exercise Price
as a result of the calculations made in Subsections 2.3(b) and (c) above, each
Right outstanding immediately prior to the making of such adjustment shall
thereafter evidence the right to purchase, at the adjusted Exercise Price, that
number of Common Shares (calculated to the nearest one ten-thousandth) obtained
by (A) multiplying (x) the number of shares purchasable upon exercise of a Right
immediately prior to this adjustment by (y) the Exercise Price in effect
immediately prior to such adjustment of the Exercise Price, and (B) dividing the
product so obtained by the Exercise Price in effect immediately after such
adjustment of the Exercise Price.
 
     (i) ELECTION TO ADJUST NUMBER OF RIGHTS UPON ADJUSTMENT TO EXERCISE PRICE.
The Corporation shall be entitled to elect on or after the date of any
adjustment of the Exercise Price to adjust the number of Rights, in lieu of any
adjustment in the number of Common Shares purchasable upon the exercise of a
Right. Each of the Rights outstanding after the adjustment in the number of
Rights shall be exercisable for the number of Common Shares for which a Right
was exercisable immediately prior to such adjustment. Each Right held of record
prior to such adjustment of the number of Rights shall become that number of
Rights (calculated to the nearest one ten-thousandth) obtained by dividing the
Exercise Price in effect immediately prior to adjustment of the Exercise Price
by the Exercise Price in effect immediately after adjustment of the Exercise
Price. The Corporation shall make a public announcement of its election to
adjust the number of Rights, indicating the record date for the adjustment, and,
if known at the time, the amount of the adjustment to be made. This record date
may be the date on which the Exercise Price is adjusted or any day thereafter,
but, if Rights Certificates have been issued, shall be at least ten (10) days
later than the date of the public announcement. If Rights Certificates have been
issued, upon each adjustment, of the number of Rights pursuant to this
Subsection 2.3(i), the Corporation shall, as promptly as practicable, cause to
be distributed to holders of record of Rights Certificates on such record date
Rights Certificates evidencing, subject to Section 5.5 hereof, the additional
Rights to which such holders shall be entitled as a result of such adjustment,
or, at the option of the Corporation, shall cause to be distributed to such
holders of record in substitution and replacement for the Rights Certificates
held by such holders prior to the date of adjustment, and upon surrender
thereof, new Rights Certificates evidencing all the Rights to which such holders
shall be entitled after such adjustment. Rights Certificates so to be
distributed shall be issued, executed and countersigned in the manner provided
for herein and may bear, at the option of the Corporation, the adjusted Exercise
Price and shall be registered in the names of the holders of record of Rights
Certificates on the record date for the adjustment specified in the public
announcement.
 
     (j) RIGHTS CERTIFICATES MAY CONTAIN EXERCISE PRICE BEFORE ADJUSTMENT.
Irrespective of any adjustment or change in the Exercise Price or the number of
Common Shares issuable upon the exercise of the Rights, the Rights Certificates
theretofore and thereafter issued may continue to express the Exercise Price per
share and the number of shares which were expressed in the initial Rights
Certificates issued hereunder.
 
     (k) CORPORATION MAY IN CERTAIN CASES DEFER ISSUES OF SECURITIES. In any
case in which this Section 2.3 shall require that an adjustment in the Exercise
Price be made effective as of a record date for a specified event, the
Corporation may elect to defer until the occurrence of such event the issuance
to the holder of any Right exercised after such record date the number of Common
Shares and other securities of the Corporation, if any, issuable upon such
exercise over and above the number of Common Shares and other securities of the
 
                                       16
<PAGE>   43
 
Corporation, if any, issuable upon such exercise on the basis of the Exercise
Price in effect prior to such adjustment; provided, however, that the
Corporation shall deliver to such holder an appropriate instrument evidencing
such holder's right to receive such additional shares (fractional or otherwise)
or securities upon the occurrence of the event requiring such adjustment.
 
     (l) CORPORATION HAS DISCRETION TO REDUCE EXERCISE PRICE FOR TAX REASONS.
Notwithstanding anything in this Section 2.3 to the contrary, the Corporation
shall be entitled to make such reductions in the Exercise Price, in addition to
those adjustments expressly required by this Section 2.3, as and to the extent
that in their good faith judgment, the Board of Directors shall determine to be
advisable in order that any (A) consolidation or subdivision of the Common
Shares, (B) issuance of any Common Shares at less than the Market Price, (C)
issuance of securities convertible into or exchangeable for Common Shares, (D)
stock dividends or (E) issuance of rights, options or warrants, referred to in
this Section 2.3 hereafter made by the Corporation to holders of its Common
Shares, shall not be taxable to such shareholders.
 
2.4 DATE ON WHICH EXERCISE IS EFFECTIVE
 
     Each person in whose name any certificate for Common Shares is issued upon
the exercise of Rights, shall for all purposes be deemed to have become the
holder of record of the Common Shares represented thereby on, and such
certificate shall be dated, the date upon which the Rights Certificate
evidencing such Rights was duly surrendered (together with a duly completed
Election to Exercise) and payment of the Exercise Price for such Rights (and any
applicable transfer taxes and other governmental charges payable by the
exercising holder hereunder) was made; provided, however, that if the date of
such surrender and payment is a date upon which the Common Share transfer books
of the Corporation are closed, such person shall be deemed to have become the
record holder of such shares on, and such certificate shall be dated, the next
succeeding Business Day on which the Common Share transfer books of the
Corporation are open.
 
2.5 EXECUTION, AUTHENTICATION, DELIVERY AND DATING OF RIGHTS CERTIFICATES
 
     (a) The Rights Certificates shall be executed on behalf of the Corporation
by its President or any of its Vice-Presidents, together with its Secretary or
Assistant Secretary. The signature of any of these officers on the Rights
Certificates may be manual or facsimile. Rights Certificates bearing the manual
or facsimile signatures of individuals who were at any time the proper officers
of the Corporation shall bind the Corporation, notwithstanding that such
individuals or any of them have ceased to hold such offices prior to the
countersignature and delivery of such Rights Certificates.
 
     (b) Promptly after the Corporation learns of the Separation Time, the
Corporation will notify the Rights Agent of such Separation Time and will
deliver Rights Certificates executed by the Corporation to the Rights Agent for
countersignature, and the Rights Agent shall manually countersign and send such
Rights Certificates to the holders of the Rights pursuant to Subsection 2.2(c)
hereof. No Rights Certificate shall be valid for any purpose until countersigned
by the Rights Agent as aforesaid.
 
     (c) Each Rights Certificate shall be dated the date of countersignature
thereof.
 
2.6 REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE
 
     (a) The Corporation will cause to be kept a register (the "Rights
Register") in which, subject to such reasonable regulations as it may prescribe,
the Corporation will provide for the registration and transfer of Rights. The
Rights Agent is hereby appointed "Rights Registrar" for the purpose of
maintaining the Rights Register for the Corporation and registering Rights and
transfers of Rights as herein provided. In the event that the Rights Agent shall
cease to be the Rights Registrar, the Rights Agent will have the right to
examine the Rights Register at all reasonable times.
 
     After the Separation Time and prior to the Expiration Time, upon surrender
for registration of transfer or exchange of any Rights Certificate and subject
to the provisions of Subsection 2.6(c) below and the other provisions of this
Agreement, the Corporation will execute and the Rights Agent will manually
countersign and deliver, in the name of the holder or the designated transferee
or transferees as required pursuant to the
 
                                       17
<PAGE>   44
 
holder's instructions, one or more new Rights Certificates evidencing the same
aggregate number of Rights as did the Rights Certificates so surrendered.
 
     (b) All Rights issued upon any registration of transfer or exchange of
Rights Certificates shall be the valid obligations of the Corporation, and such
Rights shall be entitled to the same benefits under this Agreement as the Rights
surrendered upon such registration of transfer or exchange.
 
     (c) Every Rights Certificate surrendered for registration of transfer or
exchange shall be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Corporation or the Rights Agent, as the
case may be, duly executed by the holder thereof or such holder's attorney duly
authorized in writing. As a condition to the issuance of any new Rights
Certificate under this Section 2.6, the Corporation or the Rights Agent may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and the Corporation may require
payment of a sum sufficient to cover any other expenses (including the fees and
expenses of the Rights Agent) in connection therewith.
 
2.7 MUTILATED, DESTROYED, LOST AND STOLEN RIGHT CERTIFICATES
 
     (a) If any mutilated Rights Certificate is surrendered to the Rights Agent
prior to the Expiration Time, the Corporation shall execute and the Rights Agent
shall manually countersign and deliver in exchange therefor a new Rights
Certificate evidencing the same number of Rights as did the Rights Certificate
so surrendered.
 
     (b) If there shall be delivered to the Corporation and the Rights Agent
prior to the Expiration Time (i) evidence to their reasonable satisfaction of
the destruction, loss or theft of any Rights Certificate, and (ii) such
indemnity or other security as may be required by them to save each of them and
any of their agents harmless, then, in the absence of notice to the Corporation
or the Rights Agent that such Rights Certificate has been acquired by a bona
fide purchaser, the Corporation shall execute and upon its request the Rights
Agent shall countersign and deliver, in lieu of any such destroyed, lost or
stolen Rights Certificate, a new Rights Certificate evidencing the same number
of Rights as did the Rights Certificate so destroyed, lost or stolen.
 
     (c) As a condition to the issuance of any new Rights Certificate under this
Section 2.7, the Corporation or the Rights Agent may require the payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto and the Corporation may require payment of a sum sufficient
to cover any other expenses (including the fees and expenses of the Rights
Agent) in connection therewith.
 
     (d) Every new Rights Certificate issued pursuant to this Section 2.7 in
lieu of any destroyed, lost or stolen Rights Certificate shall evidence an
original additional contractual obligation of the Corporation, whether or not
the destroyed lost or stolen Rights Certificate shall be at any time enforceable
by anyone, and the holder thereof shall be entitled to all the benefits of this
Agreement equally and proportionately with any and all other holders of Rights
duly issued by the Corporation.
 
2.8 PERSONS DEEMED OWNERS
 
     Prior to due presentment of a Rights Certificate (or, prior to the
Separation Time, the associated Common Share certificate) for registration of
transfer, the Corporation, the Rights Agent and any agent of the Corporation or
the Rights Agent shall be entitled to deem and treat the person in whose name a
Rights Certificate (or, prior to the Separation Time, the associated Common
Share certificate) is registered as the absolute owner thereof and of the Rights
evidenced thereby for all purposes whatsoever. As used in this Agreement, unless
the context otherwise requires, the term "holder" of any Rights shall mean the
registered holder of such Rights (or, prior to the Separation Time, the
associated Common Shares).
 
2.9 DELIVERY AND CANCELLATION OF RIGHTS CERTIFICATES
 
     All Rights Certificates surrendered upon exercise or for redemption,
registration of transfer or exchange shall, if surrendered to any person other
than the Rights Agent, be delivered to the Rights Agent and, in any case, shall
be promptly cancelled by the Rights Agent. The Corporation may at any time
deliver to the Rights
 
                                       18
<PAGE>   45
 
Agent for cancellation any Rights Certificates previously countersigned and
delivered hereunder which the Corporation may have acquired in any manner
whatsoever, and all Rights Certificates so delivered shall be promptly cancelled
by the Rights Agent. No Rights Certificate shall be countersigned in lieu of or
in exchange for any Rights Certificates cancelled as provided in this Section
2.9 except as expressly permitted by this Agreement. The Rights Agent shall
destroy all cancelled Rights Certificates and deliver a certificate of
destruction to the Corporation.
 
2.10 AGREEMENT OF RIGHTS HOLDERS
 
     Every holder of Rights, by accepting the same, consents and agrees with the
Corporation and the Rights Agent and with every other holder of Rights:
 
     (i)   to be bound by and subject to the provisions of this Agreement, as
        amended or supplemented from time to time in accordance with the terms
        hereof, in respect of all Rights held;
 
     (ii)  that prior to the Separation Time each Right will be transferable
        only together with, and will be transferred by a transfer of, the Common
        Share certificate representing such Right;
 
     (iii) that after the Separation Time, the Rights Certificates will be
        transferable only on the Rights Register as provided herein;
 
     (iv) that prior to due presentment of a Rights Certificate (or, prior to
        the Separation Time, the associated Common Share certificate) for
        registration of transfer, the Corporation, the Rights Agent and any
        agent of the Corporation or the Rights Agent shall be entitled to deem
        and treat the person in whose name the Rights Certificate (or prior to
        the Separation Time, the associated Common Share certificate) is
        registered as the absolute owner thereof and of the Rights evidenced
        thereby (notwithstanding any notations of ownership or writing on such
        Rights Certificate or the associated Common Share certificate made by
        anyone other than the Corporation or the Rights Agent) for all purposes
        whatsoever, and neither the Corporation nor the Rights Agent shall be
        affected by any notice to the contrary;
 
     (v)  that such holder of Rights has waived his right to receive any
        fractional Rights or any fractional shares upon exercise of Right; and
 
     (vi) that without the approval of any holder of Rights and upon the sole
        authority of the Board of Directors acting in good faith this Agreement
        may be supplemented or amended from time to time pursuant to and as
        provided herein.
 
2.11 RIGHTS CERTIFICATE HOLDER NOT DEEMED A SHAREHOLDER
 
     No holder, as such, of any Rights or Rights Certificate shall be entitled
to vote, receive dividends or be deemed for any purpose whatsoever the holder of
any Common Share or any other share or security of the Corporation which may at
any time be issuable on the exercise of the Rights represented thereby, nor
shall anything contained herein or in any Rights Certificate be construed or
deemed to confer upon the holder of any Right or Rights Certificate, as such,
any of the rights, titles, benefits or privileges of a holder of Common Shares
or any other shares or securities of the Corporation or any right to vote at any
meeting of shareholders of the Corporation whether for the election of directors
or otherwise or upon any matter submitted to holders of shares of the
Corporation at any meeting thereof, or to give or withhold consent to any action
of the Corporation, or to receive notice of any meeting or other action
affecting any holder of Common Shares or any other shares or securities of the
Corporation except as expressly provided herein, or to receive dividends,
distributions or subscription rights, or otherwise, until the Right or Rights
evidenced by Rights Certificates shall have been duly exercised in accordance
with the terms and provisions hereof.

                     ARTICLE 3 -- ADJUSTMENTS TO THE RIGHTS
                      IN THE EVENT OF CERTAIN TRANSACTIONS
 
3.1 FLIP-IN EVENT
 
     (a) Subject to Subsection 3.1(b) below, and Subsections 5.1(b), 5.1(c) and
5.1(d) hereof, in the event that prior to the Expiration Time a Flip-in Event
shall occur, the Corporation shall take such action as may be necessary to
ensure and provide within eight (8) Business Days of such occurrence, or such
longer period as may be required to satisfy all applicable requirements of the
Securities Act (Ontario), and the securities legislation of each other province
of Canada and, if applicable, of the United States of America that, except as
provided below, each Right shall thereafter constitute the right to purchase
from the Corporation upon exercise thereof in accordance with the terms hereof
that number of Common Shares of the Corporation having an aggregate Market Price
on the date of the occurrence of such Flip-in Event equal to twice the Exercise
Price for an amount in cash equal to the Exercise Price (such Right to be
appropriately adjusted in a manner analogous to the applicable adjustment
provided for in Section 2.3 hereof in the event that after such date of
occurrence an event of a type analogous to any of the events described in
Section 2.3 hereof shall have occurred with respect to such Common Shares).
 
     (b) Notwithstanding anything in this Agreement to the contrary, upon the
occurrence of any Flip-in Event, any Rights that are Beneficially Owned by (i)
an Acquiring Person or any Affiliate or Associate of an Acquiring Person or any
Person acting jointly or in concert with an Acquiring Person or any Affiliate or
Associate of such Acquiring Person, or any Affiliate or Associate of such Person
so acting jointly or in concert, or (ii) a transferee or other successor in
title of Rights, directly or indirectly, of an Acquiring Person (or of any
Affiliate or Associate of an Acquiring Person) or of any Person acting jointly
or in concert with an Acquiring Person or any Associate or Affiliate of an
Acquiring Person who becomes a transferee or successor in title concurrently
with or subsequent to the Acquiring Person becoming such, shall become null and
void without any further action, and any holder of such Rights (including
transferees or successors in title) shall not have any rights whatsoever to
exercise such Rights under any provision of this Agreement and shall not have
thereafter any other rights whatsoever with respect to such Rights, whether
under any provision of this Agreement or otherwise.
 
                         ARTICLE 4 -- THE RIGHTS AGENT
 
4.1 GENERAL
 
     (a) The Corporation hereby appoints the Rights Agent to act as agent for
the Corporation in accordance with the terms and conditions hereof, and the
Rights Agent hereby accepts such appointment. The Corporation may from time to
time appoint such co-Rights Agents as it may deem necessary or desirable. In the
event the Corporation appoints one or more co-Rights Agents, the respective
duties of the Rights Agents and co-Rights Agents shall be as the Corporation may
determine. The Corporation agrees to pay to the Rights Agent reasonable
compensation for all services rendered by it hereunder and, from time to time,
on demand of the Rights Agent, its reasonable expenses and other disbursements
incurred in the administration and execution of this Agreement and the exercise
and performance of its duties hereunder. The Corporation also agrees to
indemnify the Rights Agent for, and to hold it harmless against, any loss,
liability, or expense incurred that is not the result of negligence, bad faith
or wilful misconduct on the part of any one or all of the Rights Agent, its
officers, employees or other representatives, for anything done or omitted by
the Rights Agent in connection with the acceptance and administration of this
Agreement, including the costs and expenses of defending against any claim of
liability, which right to indemnification will survive the termination of this
Agreement.
 
     (b) The Rights Agent shall be protected and shall incur no liability for or
in respect of any action taken, suffered or omitted by it in connection with its
administration of this Agreement in reliance upon any certificate for Common
Shares or any Rights Certificate or certificate for other securities of the
Corporation, instrument of assignment or transfer, power of attorney,
endorsement, affidavit, letter, notice, direction,
 
                                       20
<PAGE>   47
 
consent, certificate, statement, or other paper or document believed by it to be
genuine and to be signed, executed and, where necessary, verified or
acknowledged, by the proper Person or Persons.
 
4.2 MERGER OR AMALGAMATION OR CHANGE OF NAME OF RIGHTS AGENT
 
     (a) Any corporation into which the Rights Agent or any successor Rights
Agent may be merged or amalgamated or with which it may be consolidated, or any
corporation resulting from any merger, amalgamation, statutory arrangement or
consolidation to which the Rights Agent or any successor Rights Agent is a
party, or any corporation succeeding to the shareholder or stockholder services
business of the Rights Agent or any successor Rights Agent, will be the
successor to the Rights Agent under this Agreement without the execution or
filing of any paper or any further act on the part of any of the parties hereto,
provided that such corporation would be eligible for appointment as a successor
Rights Agent under the provisions of Section 4.4 hereof. In case at the time
such successor Rights Agent succeeds to the agency created by this Agreement any
of the Rights Certificates have been countersigned but not delivered, any such
successor Rights Agent may adopt the countersignature of the predecessor Rights
Agent and deliver such Rights Certificates so countersigned; and in case at that
time any of the Rights Certificates have not been countersigned, any successor
Rights Agent may countersign such Rights Certificates either in the name of the
predecessor Rights Agent or in the name of the successor Rights Agent; and in
all such cases such Rights Certificates will have the full force provided in the
Rights Certificates and in this Agreement.
 
     (b) In case at any time the name of the Rights Agent is changed and at such
time any of the Rights Certificates shall have been countersigned but not
delivered, the Rights Agent may adopt the countersignature under its prior name
and deliver Rights Certificates so countersigned; and in case at that time any
of the Rights Certificates shall not have been countersigned, the Rights Agent
may countersign such Rights Certificates either in its prior name or in its
changed name; and in all such cases such Rights Certificates shall have the full
force provided in the Rights Certificates and in this Agreement.
 
4.3 DUTIES OF RIGHTS AGENT
 
     The Rights Agent undertakes the duties and obligations imposed by this
Agreement upon the following terms and conditions, to all of which the
Corporation and the holders of Rights Certificates, by their acceptance thereof,
shall be bound.
 
     (a) The Rights Agent may consult with legal counsel (who may be legal
counsel for the Corporation) and the opinion of such counsel will be full and
complete authorization and protection to the Rights Agent as to any action taken
or omitted to be taken by it in good faith and in accordance with such opinion.
Subject to the prior written consent of the Corporation, which consent shall not
be unreasonably withheld, the Rights Agent may also consult with such other
experts as the Rights Agent shall consider necessary or appropriate to properly
carry out the duties and obligations imposed under this Agreement (at the
expense of the Corporation) and the Rights Agent shall be entitled to act and
rely in good faith on the advice of any such expert.
 
     (b) Whenever in the performance of its duties under this Agreement the
Rights Agent deems it necessary or desirable that any fact or matter be proved
or established by the Corporation prior to taking or suffering any action
hereunder, such fact or matter (unless other evidence in respect thereof be
herein specifically prescribed) may be deemed to be conclusively proven and
established by a certificate signed by a person believed by the Rights Agent to
be the Chairman of the Board, the President or any Vice-President, the Treasurer
or the Secretary of the Corporation and delivered to the Rights Agent; and such
certificate will be full authorization to the Rights Agent for any action taken
or suffered in good faith by it under the provisions of this Agreement in
reliance upon such certificate.
 
     (c) The Rights Agent will be liable hereunder only for events which are the
result of its own negligence, bad faith or wilful misconduct and that of its
officers, employees and other representatives.
 
     (d) The Rights Agent will not be liable for or by reason of any of the
statements of fact or recitals contained in this Agreement or in the
certificates for Common Shares or the Rights Certificates (except its
 
                                       21
<PAGE>   48
 
countersignature thereof) or be required to verify the same, but all such
statements and recitals are and will be deemed to have been made by the
Corporation only.
 
     (e) The Rights Agent will not be under any responsibility in respect of the
validity of this Agreement or the execution and delivery hereof (except the due
authorization, execution and delivery hereof by the Rights Agent) or in respect
of the validity or execution of any Common Share certificate or Rights
Certificate (except its countersignature thereof); nor will it be responsible
for any breach by the Corporation of any covenant or condition contained in this
Agreement or in any Rights Certificate; nor will it be responsible for any
change in the exercisability of the Rights (including the Rights becoming void
pursuant to Subsection 3.1(b) hereof) or any adjustment required under the
provisions of Section 2.3 hereof or responsible for the manner, method or amount
of any such adjustment or the ascertaining of the existence of facts that would
require any such adjustment (except with respect to the exercise of Rights after
receipt of the certificate contemplated by Section 2.3 hereof describing any
such adjustment); nor will it by any act hereunder be deemed to make any
representation or warranty as to the authorization of any Common Shares to be
issued pursuant to this Agreement or any Rights or as to whether any Common
Shares will, when issued, be duly and validly authorized, executed, issued and
delivered or fully paid and non-assessable.
 
     (f) The Corporation agrees that it will perform, execute, acknowledge and
deliver or cause to be performed, executed, acknowledged, and delivered all such
further and other acts, instruments and assurances as may reasonably be required
by the Rights Agent for the carrying out or performing by the Rights Agent of
the provisions of this Agreement.
 
     (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from any
person believed by the Rights Agent to be the Chairman of the Board, President,
any Vice-President, Treasurer or any Assistant Treasurer or the Secretary or any
Assistant Secretary of the Corporation and to apply to such persons for advice
or instructions in connection with its duties, and it shall not be liable for
any action taken or suffered by it in good faith in accordance with instructions
of any such person.
 
     (h) The Rights Agent and any shareholder or stockholder, director, officer
or employee of the Rights Agent may buy, sell or deal in Common Shares, Rights
or other securities of the Corporation or become pecuniarily interested in any
transaction in which the Corporation may be interested or contract with or lend
money to the Corporation or otherwise act as fully and freely as though it were
not Rights Agent under this Agreement. Nothing herein shall preclude the Rights
Agent from acting in any other capacity for the Corporation or for any other
legal entity.
 
4.4 CHANGE OF RIGHTS AGENT
 
     The Rights Agent may resign and be discharged from its duties under this
Agreement upon ninety (90) days' notice (or such lesser notice as is acceptable
to the Corporation) in writing mailed to the Corporation and to each transfer
agent of Voting Shares of the Corporation by registered or certified mail, and
to the holders of the Rights in accordance with Section 5.8 hereof. The
Corporation may remove the Rights Agent upon thirty (30) days' notice in
writing, mailed to the Rights Agent and to each transfer agent of the Voting
Shares of the Corporation by registered or certified mail and to the holders of
the Rights in accordance with Section 5.8 hereof. If the Rights Agent should
resign or be removed or otherwise become incapable of acting, the Corporation
will appoint a successor to the Rights Agent. If the Corporation fails to make
such appointment within a period of ninety (90) days after such removal or after
it has been notified in writing of such resignation or incapacity by the
resigning or incapacitated Rights Agent or by the holder of any Rights (which
holder shall, with such notice, submit such holder's Rights Certificate for
inspection by the Corporation), then the holder of any Rights may apply to any
court of competent jurisdiction for the appointment of a new Rights Agent. Any
successor Rights Agent, whether appointed by the Corporation or by such a court,
shall be a corporation incorporated under the laws of Canada or a province
thereof authorized to carry on the business of a trust company in Canada. After
appointment, the successor Rights Agent will be vested with the same powers,
rights, duties and responsibilities as if it had been originally named as Rights
Agent without further act or deed; but the predecessor Rights Agent, upon
receiving from the Corporation
 
                                       22
<PAGE>   49
 
payment in full of all amounts outstanding under this Agreement, shall deliver
and transfer to the successor Rights Agent any property at the time held by it
hereunder, and execute and deliver any further assurance, conveyance, act or
deed necessary for the purpose. Not later than the effective date of any such
appointment, the Corporation will file notice thereof in writing with the
predecessor Rights Agent and each transfer agent of the Voting Shares of the
Corporation, and mail a notice thereof in writing to the holders of the Rights.
The cost of giving any notice required under this Section 4.4 shall be borne
solely by the Corporation. Failure to give any notice provided for in this
Section 4.4 however, or any defect therein, shall not affect the legality or
validity of the resignation or removal of the Rights Agent or the appointment of
the successor Rights Agent, as the case may be.
 
                           ARTICLE 5 -- MISCELLANEOUS
 
5.1 REDEMPTION AND WAIVER
 
     (a) Subject to the prior consent of the holders of Voting Shares or Rights
obtained as set forth in Subsections 5.4(b) or 5.4(c) hereof, as applicable, the
Board of Directors acting in good faith may, at any time prior to the occurrence
of a Flip-in Event, elect to redeem all but not less than all of the then
outstanding Rights at a redemption price of $0.0001 per Right appropriately
adjusted in a manner analogous to the applicable adjustment provided for in
Section 2.3 hereof in the event that an event of the type described in Section
2.3 hereof shall have occurred (such redemption price being herein referred to
as the "Redemption Price").
 
     (b) Subject to the prior consent of the holders of Voting Shares obtained
as set forth in Subsection 5.4(b) hereof, the Board of Directors may at any time
prior to the occurrence of a Flip-in Event as to which the application of
Section 3.1 has not been waived pursuant to this Section 5.1, if such Flip-in
Event would occur by reason of an acquisition of Voting Shares otherwise than
pursuant to a Take-over Bid made by means of a Take-over Bid circular to all
holders of record of Voting Shares and otherwise than in the circumstances set
forth in subsection 5.1(d), waive the application of Section 3.1 to such Flip-in
Event. In such event, the Board of Directors shall extend the Separation Time to
a date at least ten (10) Business Days subsequent to the meeting of shareholders
called to approve such waiver.
 
     (c) The Board of Directors acting in good faith, may, prior to the
occurrence of a Flip-in Event, and upon prior written notice delivered to the
Rights Agent, determine to waive the application of Section 3.1 hereof to a
Flip-in Event that may occur by reason of a Take-over Bid made by means of a
take-over bid circular to all holders of record of Voting Shares (which for
greater certainty shall not include the circumstances described in Subsection
5.1(i) below); provided that if the Board of Directors waives the application of
Section 3.1 hereof to a particular Flip-in Event pursuant to this Subsection
5.1(c), the Board of Directors shall be deemed to have waived the application of
Section 3.1 hereof to any other Flip-in Event occurring by reason of any
Take-over Bid made by means of a take-over bid circular to all holders of record
of Voting Shares prior to the expiry of any Take-over Bid in respect of which a
waiver is, or is deemed to have been granted, pursuant to this Subsection
5.1(c).
 
     (d) The Board of Directors may, prior to the close of business on the tenth
(10th) day following the Stock Acquisition Date, determine, upon prior written
notice delivered to the Rights Agent, to waive or to agree to waive the
application of Section 3.1 hereof to a Flip-in Event, provided that both of the
following conditions are satisfied:
 
     (i)   the Board of Directors has determined that a Person became an
        Acquiring Person by inadvertence and without any intention to become, or
        knowledge that Person would become, an Acquiring Person; and
 
     (ii)  such Acquiring Person has reduced its Beneficial Ownership of Voting
        Shares (or has entered into a contractual arrangement with the
        Corporation, acceptable to the Board of Directors, to do so within
        thirty (30) days of the date on which such contractual arrangement is
        entered into) such
 
                                       23
<PAGE>   50
 
        that at the time the waiver becomes effective pursuant to this
        Subsection 5.1(d) it is no longer an Acquiring Person;
 
and in the event of such a waiver, for the purposes of this Agreement, the
Flip-in Event shall be deemed never to have occurred.
 
     (e) Where a Person acquires pursuant to a Permitted Bid, a Competing Bid or
an Exempt Acquisition under Subsection 5.1(c) above, outstanding Voting Shares,
other than Voting Shares Beneficially Owned by such Person at the date of the
Permitted Bid, the Competing Bid or the Exempt Acquisition under Subsection
5.1(c) above, then the Corporation shall immediately upon the consummation of
such acquisition redeem the Rights at the Redemption Price.
 
     (f) If the Corporation is obligated under Subsection 5.1(e) above to redeem
the Rights, or if the Board of Directors elects under Subsection 5.1(a) above or
5.1(h) below to redeem the Rights, the right to exercise the Rights will
thereupon, without further action and without notice, terminate and each Right
will after redemption be null and void and the only right thereafter of the
holders of Rights shall be to receive the Redemption Price.
 
     (g) Within ten (10) days after the Corporation is obligated under
Subsection 5.1(e) above to redeem the Rights, or the Board of Directors elects
under Subsection 5.1(a) above or 5.1(h) below to redeem the Rights, the
Corporation shall give notice of redemption to the holders of the then
outstanding Rights by mailing such notice to all such holders at their last
address as they appear upon the Rights Register or, prior to the Separation
Time, on the registry books of the Transfer Agent for the Common Shares. Any
notice which is mailed in the manner herein provided shall be deemed given,
whether or not the holder receives the notice. Each such notice of redemption
will state the method by which the payment of the Redemption Price will be made.
The Corporation may not redeem, acquire or purchase for value any Rights at any
time in any manner other than that specifically set forth in this Section 5.1
and other than in connection with the purchase of Common Shares prior to the
Separation Time.
 
     (h) Where a Take-over Bid that is not a Permitted Bid Acquisition is
withdrawn or otherwise terminated after the Separation Time has occurred and
prior to the occurrence of a Flip-in Event, the Board of Directors may elect to
redeem all the outstanding Rights at the Redemption Price.
 
     (i) Upon the Rights being redeemed pursuant to Subsection 5.1(h) above, all
the provisions of this Agreement shall continue to apply as if the Separation
Time had not occurred and Rights Certificates representing the number of Rights
held by each holder of record of Common Shares as of the Separation Time had not
been mailed to each such holder and for all purposes of this Agreement the
Separation Time shall be deemed not to have occurred.
 
5.2 EXPIRATION
 
     No person shall have any rights whatsoever pursuant to or arising out of
this Agreement or in respect of any Right after the Expiration Time, except the
Rights Agent as specified in Subsection 4.1(a) hereof.
 
5.3 ISSUANCE OF NEW RIGHTS CERTIFICATES
 
     Notwithstanding any of the provisions of this Agreement or of the Rights to
the contrary, the Corporation may, at its option, issue new Rights Certificates
evidencing Rights in such form as may be approved by its Board of Directors to
reflect any adjustment or change in the number or kind or class of shares
purchasable upon exercise of Rights made in accordance with the provisions of
this Agreement.
 
5.4 SUPPLEMENTS AND AMENDMENTS
 
     (a) The Corporation may from time to time supplement or amend this
Agreement without the approval of any holders of Rights or Voting Shares or
Debentures to correct any clerical or typographical error or to maintain the
validity of the Agreement as a result of a change in any applicable legislation
or regulations thereunder.
 
                                       24
<PAGE>   51
 
     Notwithstanding anything in this Section 5.4 to the contrary, no supplement
or amendment shall be made to the provisions of Article 4 hereof except with the
written concurrence of the Rights Agent to such supplement or amendment.
 
     (b) Subject to Subsection 5.4(a) above, the Corporation may, with the prior
consent of the holders of the Voting Shares obtained as set forth below, at any
time prior to the Separation Time amend, vary or rescind any of the provisions
of this Agreement and the Rights (whether or not such action would materially
adversely affect the interests of the holders of Rights generally). Such consent
shall be deemed to have been given if provided by the holders of Voting Shares
at a meeting of the holders of Voting Shares, which meeting shall be called and
held in compliance with applicable laws and regulatory requirements and the
requirements in the articles and by-laws of the Corporation. Subject to
compliance with any requirements imposed by the foregoing, consent shall be
deemed to have been given if the proposed amendment, variation or revision is
approved by the affirmative vote of a majority of the votes cast by all holders
of Voting Shares (other than any holder of Voting Shares who is an Offeror
pursuant to a Take-over Bid that is not a Permitted Bid or Competing Bid with
respect to all Voting Shares Beneficially Owned by such Person), represented in
person or by proxy at the meeting.
 
     (c) The Corporation may, with the prior consent of the holders of Rights,
at any time after the Separation Time and before the Expiration Time, amend,
vary or rescind any of the provisions of this Agreement and the Rights (whether
or not such action would materially adversely affect the interests of the
holders of Rights generally).
 
     (d) Any approval of the holders of Rights shall be deemed to have been
given if the action requiring such approval is authorized by the affirmative
votes of the holders of Rights present or represented at and entitled to be
voted at a meeting of the holders of Rights and representing a majority of the
votes cast in respect thereof. For the purposes hereof, each outstanding Right
(other than Rights which are void pursuant to the provisions hereof) shall be
entitled to one vote, and the procedures for the calling, holding and conduct of
the meeting shall be those, as nearly as may be, which are provided in the
Corporation's by-laws and the Business Corporations Act (Ontario) with respect
to a meeting of shareholders of the Corporation.
 
     (e) The Corporation shall be required to provide the Rights Agent with
notice in writing of any such amendment, variation or deletion to this Agreement
as referred to in this Section 5.4 within 5 days of effecting such amendment,
variation or deletion.
 
     (f) Any supplements or amendments made by the Corporation to this Agreement
pursuant to Subsection 5.4(a) above which are required to maintain the validity
of this Agreement as a result of any change in any applicable legislation or
regulations thereunder shall:
 
     (i)   if made before the Separation Time, be submitted to the shareholders
        of the Corporation at the next meeting of shareholders and the
        shareholders may, by the majority referred to in Subsection 5.4(b) above
        confirm or reject such amendment;
 
     (ii)  if made after the Separation Time, be submitted to the holders of
        Rights at a meeting to be called for on a date not later than
        immediately following the next meeting of shareholders of the
        Corporation and the holders of Rights may, by resolution passed by the
        majority referred to in Subsection 5.4(d) above, confirm or reject such
        amendment.
 
     A supplement or amendment shall be effective from the date of the
resolution of the Board of Directors adopting such supplement or amendment until
it is confirmed or rejected or until it ceases to be effective (as described in
the next sentence) and, where such supplement or amendment is confirmed, it
continues in effect in the form so confirmed. If such supplement or amendment is
rejected by the shareholders or the holders of Rights or is not submitted to the
shareholders or holders of Rights as required, then such supplement or amendment
shall cease to be effective from and after the termination of the meeting at
which it was rejected or to which it should have been but was not submitted or
from and after the date of the meeting of holders of Rights that should have
been but was not held, and no subsequent resolution of the Board of Directors to
amend, vary or delete any provision of this Agreement to substantially the same
effect shall be effective until confirmed by the shareholders or holders of
Rights, as the case may be.

5.5 FRACTIONAL RIGHTS AND FRACTIONAL SHARES
 
     (a) The Corporation shall not be required to issue fractions of Rights or
to distribute Rights Certificates which evidence fractional Rights. Any such
fractional Right shall be null and void and the Corporation will not have any
obligation or liability in respect thereof.
 
     (b) The Corporation shall not be required to issue fractions of Common
Shares or other securities upon exercise of the Rights or to distribute
certificates which evidence fractional Common Shares or other securities. In
lieu of issuing fractional Common Shares or other securities, the Corporation
shall pay to the registered holders of Rights Certificates at the time such
Rights are exercised as herein provided, an amount in cash equal to the same
fraction of the Market Price of one Common Share.
 
5.6 RIGHTS OF ACTION
 
     Subject to the terms of this Agreement, all rights of action in respect of
this Agreement, other than rights of action vested solely in the Rights Agent,
are vested in the respective registered holders of the Rights; and any
registered holder of any Rights, without the consent of the Rights Agent or of
the registered holder of any other Rights, may, on such holder's own behalf and
for such holder's own benefit and the benefit of other holders of Rights
enforce, and may institute and maintain any suit, action or proceeding against
the Corporation to enforce such holder's right to exercise such holder's Rights
in the manner provided in such holder's Rights Certificate and in this
Agreement. Without limiting the foregoing or any remedies available to the
holders of Rights, it is specifically acknowledged that the holders of Rights
would not have an adequate remedy at law for any breach of this Agreement and
will be entitled to specific performance of the obligations under, and
injunctive relief against actual or threatened violations of the obligations of
any Person subject to this Agreement.
 
5.7 NOTICE OF PROPOSED ACTIONS

the Corporation or the sale of all or substantially all of the Corporation's
assets, then, in each such case, the Corporation shall give to each holder of a
Right, in accordance with Section 5.8 hereof, a notice of such proposed action,
