ITEM 3. BANKRUPTCY AND RECEIVERSHIP

     On June 25, 1999, Philip Services Corp. (the "Company") filed a voluntary
application to reorganize under the Companies' Creditors Arrangement Act
(Canada) ("CCAA") with the Ontario Superior Court of Justice in Toronto, Canada,
and voluntary petitions under Chapter 11 of the U.S. Bankruptcy Code ("Chapter
11") with the U.S. Bankruptcy Court for the District of Delaware. On June 27,
1999, the Company obtained First Day Orders under Chapter 11 of the U.S.
Bankruptcy Code from the U.S. Bankruptcy Court for the District of Delaware.

     On September 17, 1999 the Company filed an Amended and Restated Plan of
Compromise and Arrangement under the CCAA with the Ontario Superior Court of
Justice in Toronto, Canada, and an Amended Joint Plan of Reorganization and a
Disclosure Statement under Chapter 11 with the U.S. Bankruptcy Court for the
District of Delaware.

     On September 21, 1999 the Company filed an Amended and Restated Plan of
Compromise and Arrangement (the "Amended Canadian Plan") under the CCAA with the
Ontario Superior Court of Justice in Toronto, Canada, and an Amended Joint Plan
of Reorganization (the "Amended U.S. Plan") and a Disclosure Statement under
Chapter 11 with the U.S. Bankruptcy Court for the District of Delaware.

     A confirmation hearing to confirm the Company's plan of reorganization is
scheduled for October 13, 1999 at the U.S. Bankruptcy Court for the District of
Delaware.

     The Amended Canadian and U.S. Plans provide that the claims of Canadian
creditors against the Company will be dealt with in Canada under the CCAA
proceedings. The Amended Canadian Plan provides that in the event that certain
conditions are not satisfied or Canadian unsecured creditors vote to reject the
Amended Canadian Plan, the Company can implement an alternative means of
restructuring by which the restructuring of the Company and its Canadian
subsidiaries would be accomplished by the transfer of their business as a going
concern to one or more direct or indirect subsidiaries of Philip Services
(Delaware), Inc.

     The Company's lending syndicate has confirmed its support of the Amended
Canadian and U.S. Plans. The official committee of unsecured creditors appointed
under Chapter 11 has confirmed its support of the Amended U.S. Plan and has
urged holders of unsecured claims to vote in favour of the Amended U.S. Plan.

                                   DISCLAIMER

         PHILIP SERVICES CORP. ("PSC"), PHILIP SERVICES (DELAWARE), INC. ("PSI")
AND CERTAIN OF THEIR SUBSIDIARIES LISTED ON EXHIBIT A TO THE PLAN (THE
"SUBSIDIARY DEBTORS" AND, TOGETHER WITH PSC AND PSI, THE "DEBTORS") ARE
FURNISHING THIS DISCLOSURE STATEMENT AND THE APPENDICES HERETO, THE ACCOMPANYING
BALLOTS AND THE RELATED MATERIALS DELIVERED HEREWITH PURSUANT TO SECTION 1125 OF
THE UNITED STATES BANKRUPTCY CODE, 11 U.S.C. ss.ss. 101-1330, AS AMENDED (THE
"BANKRUPTCY CODE"), IN CONNECTION WITH THEIR SOLICITATION (THE "SOLICITATION")
FROM HOLDERS OF CERTAIN CLAIMS IN CLASSES 6 AND 7 (THE "HOLDERS OF CLASS 6 AND 7
CLAIMS") OF ACCEPTANCES OF THE PROPOSED JOINT PLAN OF REORGANIZATION DESCRIBED
HEREIN (THE "PLAN," A COPY OF WHICH IS ANNEXED TO THIS DISCLOSURE STATEMENT AS
APPENDIX A). IN THE EVENT THAT HOLDERS OF CLASS 7 CLAIMS VOTE TO REJECT THE
PLAN, THE DEBTORS INTEND TO SEEK CONFIRMATION OF THE PLAN NOTWITHSTANDING SUCH
REJECTION PURSUANT TO THE CRAMDOWN PROVISION OF SECTION 1129(b) OF THE
BANKRUPTCY CODE.

         THE OFFICIAL COMMITTEE OF UNSECURED CREDITORS APPOINTED IN THESE CASES
SUPPORTS CONFIRMATION OF THE PLAN OF REORGANIZATION DETAILED HEREIN AND
URGES HOLDERS OF CLASS 7 TO VOTE IN FAVOR OF THE PLAN.

         PSC IS A COMPANY AMALGAMATED UNDER THE LAWS OF THE PROVINCE OF ONTARIO
AND WITH PROPERTY IN THE UNITED STATES, CANADA AND OTHER INTERNA TIONAL SITES.
PSI IS A CORPORATION ESTABLISHED IN THE UNITED STATES UNDER THE LAWS OF THE
STATE OF DELAWARE.

         PSC AND CERTAIN OF ITS OTHER SUBSIDIARIES THAT ARE NOT DEBTORS IN THESE
REORGANIZATION CHAPTER 11 CASES (THE "CANADIAN DEBTORS") HAVE ALSO COMMENCED
CASES IN THE SUPERIOR COURT OF JUSTICE IN TORONTO, ONTARIO, CANADA UNDER THE
COMPANIES' CREDITORS ARRANGEMENT ACT (THE "CCAA") (THE "CANADIAN CASES"). PSC
AND THE OTHER CANADIAN DEBTORS HAVE FILED IN THE CANADIAN CASES AN AMENDED PLAN
OF COMPROMISE AND ARRANGEMENT CONSISTENT WITH THE PLAN (THE "CANADIAN PLAN").
THE CANADIAN REORGANIZATION PLAN PROVIDES FOR THE REORGANIZATION OF PSC AND THE
OTHER CANADIAN DEBTORS AND THEIR EMERGENCE FROM THE CANADIAN CASES AS OPERATING
ENTITIES.

         IN THE EVENT THE CANADIAN REORGANIZATION PLAN IS NOT SANCTIONED, THE
REORGANIZATION OF PSC AND THE OTHER CANADIAN DEBTORS WILL BE ACCOMPLISHED
THROUGH THE TRANSFER OF THEIR BUSINESSES AS A GOING CONCERN TO ONE OR MORE
DIRECT OR INDIRECT SUBSIDIARIES OF REORGANIZED PSI, AS THE RESULT OF THE LENDERS
ENFORCING REMEDIES UNDER CANADIAN LAW (THE "ALTERNATE CANADIAN TRANSACTIONS").
IF THE ALTERNATE CANADIAN TRANSACTIONS ARE IMPLEMENTED, CLAIMS OF CANADIAN
CREDITORS WILL NOT BE COMPROMISED; HOWEVER, IT IS EXPECTED THAT NO DISTRIBUTIONS
WILL BE MADE TO CANADIAN CREDITORS OTHER THAN THE LENDERS.

         THE PLAN PROVIDES THAT IF THE CANADIAN REORGANIZATION PLAN IS NOT
SANCTIONED, HOLDERS OF CANADIAN IMPAIRED UNSECURED CLAIMS AGAINST THE CANADIAN
DEBTORS MAY PARTICIPATE IN DISTRIBUTIONS PROVIDED UNDER THE PLAN AS IF THEY WERE
UNITED STATES CREDITORS IF THEY VOLUNTARILY SUBMIT TO THE PERSONAL AND SUBJECT
MATTER JURISDICTION OF THE BANKRUPTCY COURT AND HAVE THEIR CLAIMS ALLOWED AND
DETERMINED IN ACCORDANCE WITH THE BANKRUPTCY CODE AND APPLICABLE NONBANKRUPTCY
LAWS OF THE UNITED STATES, BY FILING A FORM TO BE PROVIDED TO THEM
BY THE DEBTORS. ANY SUCH DISTRIBUTIONS WILL BE MADE FROM DISTRIBUTIONS THAT

                                       -i-

<PAGE>   3


WOULD OTHERWISE HAVE BEEN MADE TO HOLDERS OF CANADIAN IMPAIRED UNSECURED CLAIMS
IF THE CANADIAN REORGANIZATION PLAN WAS SANCTIONED.

         PSC AND THE OTHER CANADIAN DEBTORS WILL SEEK TO HAVE THE CANADIAN
REORGANIZATION PLAN SANCTIONED BY THE CANADIAN COURT ONLY IF CERTAIN CONDITIONS
ARE MET INCLUDING THE RESOLUTION OF CLAIMS INVOLVING THE DEBTORS' AUDITORS AND
UNDERWRITERS. IF THESE CONDITIONS ARE NOT MET PRIOR TO THE VOTE ON THE CANADIAN
PLAN, THEN PSC AND THE OTHER CANADIAN DEBTORS MAY SEEK TO HAVE THE ALTERNATE
CANADIAN TRANSACTIONS IMPLEMENTED.

         THE DEBTORS DO NOT BELIEVE THAT THERE WILL BE A MATERIAL ECONOMIC
IMPACT ON THE NATURE OR VALUE OF THE DISTRIBUTIONS TO BE MADE UNDER THE PLAN TO
HOLDERS OF CLAIMS OR INTERESTS AS A RESULT OF WHETHER THE CANADIAN
REORGANIZATION PLAN IS SANCTIONED OR THE ALTERNATE CANADIAN TRANSACTIONS ARE
IMPLEMENTED.

         THIS DISCLOSURE STATEMENT IS TO BE USED BY HOLDERS OF CLASS 6 AND 7
CLAIMS SOLELY IN CONNECTION WITH THEIR EVALUATION OF THE PLAN; USE OF THE
DISCLOSURE STATEMENT FOR ANY OTHER PURPOSE IS NOT AUTHORIZED.

         THIS DISCLOSURE STATEMENT HAS BEEN NEITHER APPROVED NOR DISAPPROVED BY
THE SECURITIES AND EXCHANGE COMMISSION (THE "SEC") OR UNDER ANY STATE SECURITIES
OR "BLUE SKY" LAWS, NOR HAS THE SEC PASSED UPON THE ACCURACY OR ADEQUACY OF THE
STATEMENTS CONTAINED HEREIN. PERSONS OR ENTITIES TRADING IN OR OTHERWISE
PURCHASING, SELLING OR TRANSFERRING SECURITIES OR CLAIMS OF ANY OF THE DEBTORS
SHOULD EVALUATE THIS DISCLOSURE STATEMENT AND THE PLAN IN LIGHT OF THE PURPOSE
FOR WHICH THEY WERE PREPARED.

         IN MAKING A DECISION, HOLDERS OF CLASS 6 AND 7 CLAIMS MUST RELY ON
THEIR OWN EXAMINATION OF THE DEBTORS AND THE TERMS OF THE PLAN, INCLUDING THE
MERITS AND RISKS INVOLVED. HOLDERS OF CLASS 6 AND 7 CLAIMS SHOULD NOT CON STRUE
THE CONTENTS OF THIS DISCLOSURE STATEMENT AS PROVIDING ANY LEGAL, BUSINESS,
FINANCIAL, OR TAX ADVICE. EACH HOLDER OF CLASS 6 AND 7 CLAIMS SHOULD CONSULT
WITH ITS OWN LEGAL, BUSINESS, FINANCIAL AND TAX ADVISORS WITH RESPECT TO ANY
SUCH MATTERS CONCERNING THIS DISCLOSURE STATEMENT, THE SOLICITATION, THE PLAN
AND THE TRANSACTIONS CONTEMPLATED THEREBY.

CONDITIONS PRECEDENT. SEE ARTICLE II.M OF THE DISCLOSURE STATEMENT, ENTITLED
"SUMMARY OF THE PLAN OF REORGANIZATION -- CONDITIONS TO CONFIRMATION AND/OR
CONSUMMATION." THERE CAN BE NO ASSURANCE THAT THOSE CONDITIONS WILL BE
SATISFIED.

         THIS DISCLOSURE STATEMENT CONTAINS CERTAIN PROJECTED FINANCIAL INFORMA
TION RELATING TO THE REORGANIZED DEBTORS, AS WELL AS CERTAIN OTHER STATEMENTS
THAT CONSTITUTE "FORWARD-LOOKING STATEMENTS" WITHIN THE MEANING OF THE PRIVATE

<PAGE>   4



ASSUMPTIONS. MANY FACTORS COULD CAUSE THE ACTUAL RESULTS, PERFORMANCE OR
ACHIEVEMENTS OF THE DEBTORS TO BE MATERIALLY DIFFERENT FROM ANY FUTURE RESULTS,
PERFORMANCE OR ACHIEVEMENTS THAT MAY BE EXPRESSED OR IMPLIED BY SUCH PROJECTED
FINANCIAL INFORMATION AND FORWARD-LOOKING STATEMENTS, INCLUDING, AMONG OTHERS,
THE RISKS DISCUSSED IN ARTICLE VII OF THE DISCLOSURE STATEMENT, ENTITLED
"CERTAIN FACTORS TO BE CONSIDERED" AND RISKS DISCUSSED FROM TIME TO TIME IN
FILINGS MADE BY THE DEBTORS WITH THE SEC AND OTHER REGULATORY AUTHORITIES.
SHOULD ONE OR MORE OF THESE RISKS OR UNCERTAINTIES MATERIALIZE, OR SHOULD
ASSUMPTIONS UNDERLYING THE PROJECTED FINANCIAL INFORMATION OR OTHER
FORWARD-LOOKING STATEMENTS PROVE INCORRECT, ACTUAL RESULTS MAY VARY MATERIALLY
FROM THOSE DESCRIBED HEREIN AS ANTICIPATED, BELIEVED, ESTIMATED OR EXPECTED. THE
DEBTORS DO NOT INTEND, AND DO NOT ASSUME ANY OBLIGATIONS, TO UPDATE THESE
FORWARD-LOOKING STATEMENTS.

         EXCEPT AS SET FORTH IN ARTICLE XIII.I OF THIS DISCLOSURE STATEMENT,
ENTITLED "THE SOLICITATION; VOTING PROCEDURES -- FURTHER INFORMATION" BELOW, NO
PERSON HAS BEEN AUTHORIZED BY THE DEBTORS IN CONNECTION WITH THE PLAN OR THE
SOLICITATION OF ACCEPTANCES TO GIVE ANY INFORMATION OR TO MAKE ANY
REPRESENTATION OTHER THAN AS CONTAINED IN THIS DISCLOSURE STATEMENT AND THE
APPENDICES AND EXHIBITS ANNEXED HERETO OR INCORPORATED BY REFERENCE OR REFERRED
TO HEREIN, AND, IF GIVEN OR MADE, SUCH INFORMATION OR REPRESENTATION MAY NOT BE
RELIED UPON AS HAVING BEEN AUTHORIZED BY THE DEBTORS.

         THE STATEMENTS CONTAINED IN THIS DISCLOSURE STATEMENT ARE MADE AS OF
THE DATE HEREOF, AND NEITHER THE DELIVERY OF THIS DISCLOSURE STATEMENT NOR ANY
EXCHANGE OF EXISTING SECURITIES MADE PURSUANT TO THE PLAN WILL, UNDER ANY
CIRCUMSTANCE, CREATE ANY IMPLICATION THAT THE INFORMATION CONTAINED HEREIN IS
CORRECT AT ANY TIME SUBSEQUENT TO THE DATE HEREOF. ANY ESTIMATES OF CLAIMS AND
INTERESTS SET FORTH IN THIS DISCLOSURE STATEMENT MAY VARY FROM THE AMOUNTS OF
CLAIMS OR INTERESTS ULTIMATELY ALLOWED BY THE BANKRUPTCY COURT.

         THE INFORMATION CONTAINED IN THIS DISCLOSURE STATEMENT, INCLUDING, BUT
NOT LIMITED TO, THE INFORMATION REGARDING THE HISTORY, BUSINESSES AND OPERATIONS
OF THE DEBTORS, THE HISTORICAL AND PROJECTED FINANCIAL INFORMATION OF THE
DEBTORS (INCLUDING THE PROJECTED RESULTS OF OPERATIONS OF THE REORGANIZED
DEBTORS) AND THE LIQUIDATION ANALYSIS RELATING TO THE DEBTORS IS INCLUDED HEREIN
FOR PURPOSES OF SOLICITING ACCEPTANCES OF THE PLAN. AS TO CONTESTED MATTERS,
HOWEVER, SUCH INFORMATION IS NOT TO BE CONSTRUED AS ADMISSIONS OR STIPULATIONS
BUT RATHER AS STATEMENTS MADE IN SETTLEMENT NEGOTIATIONS.

                      SUMMARY OF THE PLAN OF REORGANIZATION

         THIS SECTION PROVIDES A SUMMARY OF THE STRUCTURE, CLASSIFICATION,
TREATMENT AND IMPLEMENTATION OF THE PLAN AND IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO THE PLAN, WHICH ACCOMPANIES THIS DISCLOSURE STATEMENT, AND TO THE
EXHIBITS ATTACHED THERETO.

         THE PLAN ITSELF AND THE DOCUMENTS REFERRED TO THEREIN WILL CONTROL THE
TREATMENT OF CREDITORS AND EQUITY SECURITY HOLDERS UNDER THE PLAN AND WILL, UPON
THE EFFECTIVE DATE, BE BINDING UPON HOLDERS OF CLAIMS AGAINST, OR INTERESTS IN,
THE DEBTORS, THE REORGANIZED DEBTORS AND OTHER PARTIES IN INTEREST.

A.       OVERALL STRUCTURE OF THE PLAN

         Chapter 11 is the principal business reorganization chapter of the
Bankruptcy Code. Under chapter 11, a debtor is authorized to reorganize its
business for the benefit of its creditors and shareholders. Upon the filing of a
petition for relief under chapter 11, section 362 of the Bankruptcy Code
provides for an automatic stay of substantially all acts and proceedings against
the debtor and its property, including all attempts to collect claims or enforce
liens that arose prior to the commencement of the chapter 11 case.

         The consummation of a plan of reorganization is the principal objective
of a chapter 11 case. A plan of reorganization sets forth the means for
satisfying claims against and interests in a debtor. Confirmation of a plan of
reorganization by the Bankruptcy Court makes the plan binding upon the debtor,
any issuer of securities under the plan, any person or entity acquiring property
under the plan, and any creditor of or equity security holder in the debtor,
whether or not such creditor or equity security holder (i) is impaired under or
has accepted the plan or (ii) receives or retains any property under the plan.
Subject to certain limited exceptions and other than as provided in the plan
itself or the confirmation order, the confirmation order discharges the debtor
from any debt that arose prior to the date of confirmation of the plan and
substitutes therefor the obligations specified under the confirmed plan, and
terminates all rights and interests of equity security holders.

         The terms of the Plan are based upon, among other things, the Debtors'
assessment of their ability to achieve the goals of their business plan, make
the distributions contemplated under the Plan and pay certain of their
continuing obligations in the ordinary course of the Reorganized Debtors'
businesses as approved by the Bankruptcy Court. Under the Plan, Claims
against, and Interests in, the Debtors are divided into Classes according to
their seniority and other criteria.


                                        2

<PAGE>   13


         If the Plan is confirmed by the Bankruptcy Court and consummated, (i)
the Claims in certain Classes will be reinstated or modified and receive
distributions equal to the full amount of such Claims, and (ii) the Claims
and/or Interests in other Classes will be modified and receive distributions
constituting a partial recovery on such Claims and/or Interests. On the
Effective Date and at certain times thereafter, the Reorganized Debtors will
distribute Cash, securities and other property in respect of certain Classes of
Claims as provided in the Plan. The Classes of Claims against the Debtors
created under the Plan, the treatment of those Classes under the Plan and the
securities and other property to be distributed under the Plan are described
below.

         The Plan provides for alternative treatment of Claims and Interests
depending upon which of the two alternative restructurings are implemented in
the Canadian Cases for PSC and the other Canadian Debtors.

         Generally, if the Canadian Reorganization Plan is sanctioned, the Plan
provides that PSC will reorganize and remain the ultimate parent company of the
Debtors. Alternatively, if the Alternate Canadian Transactions are implemented,
the reorganization of the Canadian Debtors will be accomplished through the
transfer of the businesses of the Canadian Debtors as going concerns to one or
more direct or indirect subsidiaries of Reorganized PSI, with certain claims and
causes of action and other assets being retained by PSC and the other Canadian
Debtors, subject to the Lenders' security interests, and Reorganized PSI will
emerge from chapter 11 as the ultimate parent company of the Reorganized
Debtors. The assets of PSC and the other Canadian Debtors that would not be
acquired through the implementation of the Alternate Canadian Transactions,
which would include any claim, rights or causes of action, suits and
proceedings, whether in law or equity, whether known or unknown, that PSC and/or
the other Canadian Debtors may hold, including claims against Deloitte & Touche
and Robert Waxman, would remain assets of PSC and the other Canadian Debtors and
subject to the Lenders' security interests to the extent such Lender Claims
secured by such security interests have not been satisfied in full prior
thereto. The Lenders will retain their security interests and deficiency claims
against PSC and the other Canadian Debtors and would likely be the sole
beneficiaries of any recovery on such assets unless the recoveries cause their
debt to have been repaid in full.

         If the Canadian Reorganization Plan is implemented, the Plan provides
that as of the Effective Date, if Class 7 votes to accept the Plan: (i)
ninety-one percent (91%) of the common stock of Reorganized PSC (the common
shares of Reorganized PSC as of the Effective Date and after giving effect to
the New Common Shares to be issued under the Plan and a reverse stock split
described below are referred to as "PSC Common Shares") will be owned by the
holders of the Secured Lender Claims, (ii) five percent (5%) of PSC Common
Shares will be owned by the holders of Allowed Class 7 Claims and holders of
Canadian Impaired Unsecured Claims (as defined herein), (iii) two percent (2%)
of PSC Common Shares will be owned by the holders of Interests under Class 8A,
(iv) one-half of one percent (0.5%) of PSC Common Shares will be owned by the
holders of Claims under Class 8C, and (v) one and one-half percent (1.5%) will
be owned by the holders of Class 8B Claims and members of the Canadian Class
Action settlement class. If Class 7 votes to reject the Plan, then the holders
of Secured Lender Claims will receive ninety-five percent (95%) of PSC Common
Shares plus the PSC Common Shares that would have been available for
distribution to Class 7 had Class 7 voted to accept the Plan and no PSC Common
Shares will be owned by the holders of Interests in Class 8A, holders of Claims
in Class 8B or the holders of Claims in Class 8C. All of these percentages of
ownership of PSC Common Shares are subject to dilution subsequent to the
Effective Date (a) to the extent necessary to give effect to the convertibility
of the New Secured PIK Debt, the New Unsecured Convertible Notes and the
exercise of the Management Options or (b) otherwise as a result of the issuance
of common shares, implementation of other management incentive programs or other
action taken by the board of directors of Reorganized PSC, all as described in
more detail subsequently in this Disclosure Statement. If the Canadian
Reorganization Plan is implemented after the Effective Date, the New Securities
to be distributed as described above will be issued by Reorganized PSI as
opposed to Reorganized PSC.

         If the Alternate Canadian Transactions are implemented and if Class 7
votes to accept the Plan, (i) the holders of the Secured Lender Claims will own
ninety-one percent (91%) of Reorganized PSI Common Shares plus an amount of
Reorganized PSI Common Shares equivalent to the amount of New Common Shares that
would have been distributed to the class of holders of Canadian Impaired
Unsecured Claims if the Canadian Reorganization Plan


                                        3

was sanctioned (based on the Debtors' estimate of the allowed amount of
such claims) less an amount of New Common Shares equivalent to the amount of
Reorganized PSI Common Shares distributed to the holders of Canadian Impaired
Unsecured Claims who make the U.S. Plan Election (as described below under the
heading "Summary of the Plan of Reorganization - - Classification and Treatment
of Claims and Interests - - The U.S. Plan Election and Distributions on Account
Thereof"), (ii) the holders of Allowed Class 7 Claims (including holders of
Allowed Canadian Impaired Unsecured Claims that make the U.S. Plan Election as
described below) will own five percent (5%) of Reorganized PSI Common Shares,
less the aggregate number of Reorganized PSI Common Shares that would have been
distributed to those holders of Canadian Impaired Unsecured Claims if the
Canadian Reorganization Plan was sanctioned and, (iii) two percent (2%) of
Reorganized PSI Common Shares will be owned by the holders of Interests under
Class 8A, (iv) one-half of one percent (0.5%) of Reorganized PSI Common Shares
will be owned by the holders of Claims under Class 8C (including residents of
Canada that make the U.S. Plan Election) and (v) one and one-half percent (1.5%)
of Reorganized PSI Common Shares will be owned by the holders of Class 8B Claims
(including residents of Canada that make the U.S. Plan Election). If Class 7
votes to reject the Plan, one hundred (100%) of Reorganized PSI Common Shares
will be owned by the holders of the Secured Lender Claims. All of these
percentages of ownership of Reorganized PSI Common Shares are subject to
dilution subsequent to the Effective Date (a) to the extent necessary to give
effect to the convertibility of the New Secured PIK Debt, the New Unsecured
Convertible Notes and the exercise of the Management Options or (b) otherwise as
a result of the issuance of common shares, implementation of other management
incentive programs or other action taken by the board of directors of
Reorganized PSI, all as described in more detail subsequently in this Disclosure
Statement.

B.       SUBSTANTIVE CONSOLIDATION FOR PURPOSES OF TREATING IMPAIRED CLAIMS

         The Plan is premised upon the substantive consolidation of the Debtors
only for purposes of treating Class 6, 7 and 8 Claims under the Plan, including
voting, confirmation and distribution purposes. The Plan does not contemplate
the substantive consolidation of the Debtors with respect to other Classes of
Claims or Interests set forth in the Plan. Substantive consolidation of Classes
6, 7 and 8 solely for purposes of the Plan is appropriate in this case. As of
the Petition Date, the Debtors were, and remain, indebted, jointly and
severally, to the prepetition Lenders in the principal amount of approximately
$1 billion, together with accrued and unpaid interest and other fees, costs and
expenses. The Debtors have undertaken a preliminary review of liens and
guarantees in favor of the Lenders and believe that there are no viable causes
of action under applicable fraudulent conveyance law to avoid obligations or
liens of the Debtors to the Lenders. The going concern enterprise value of the
Debtors' consolidated businesses has been established by Ernst & Young Corporate
Finance at between $500 million and $600 million, rendering the Lenders
substantially undersecured. Because significantly all of the assets of the
Debtors are pledged to secure the obligations of the Lenders, under section 1141
of the Bankruptcy Code unsecured creditors and interest holders in Classes 7 and
8 would not be entitled to any distribution on account of their Claims. Thus any
distribution is purely as a result of the agreement of the Lenders to pass value
to those impaired classes. Accord ingly, there exists no reason in connection
with the solicitation, balloting and distribution processes to observe the
formalities of separateness among the Debtors for purposes of the solicitation
and distributions to Classes 6, 7 and 8 Claims, nor should the Debtors and these
creditors incur the additional wholly unnecessary costs that would result absent
the limited substantive consolidation proposed in the Plan.

         Pursuant to the limited substantive consolidation, on the Effective
Date (a) all guaranties of any Debtor of the payment, performance or collection
of another Debtor with respect to Class 6, 7 and 8 Claims shall be deemed
eliminated and canceled; (b) any obligation of any Debtor and all guaranties
with respect to Class 6, 7 and 8 Claims thereof executed by one or more of the
other Debtors shall be treated as a single obligation and any obligation of
two or more Debtors, and all multiple Impaired Claims against such entities on
account of such joint obligations shall be treated and Allowed only as a single
Impaired Claim against the consolidated Debtors; and (c) each Class 6, 7 and 8
Claim filed in the Chapter 11 Cases of any Debtors shall be deemed filed against
the consolidated Debtors and shall be deemed one Class 6, 7 and 8 Claim against
and obligation of the consolidated Debtors. Such substantive consolidation shall
not (other than for purposes related to the Plan) (a) affect the legal and
corporate structures of the

                                        4

<PAGE>   15


Reorganized Debtors, subject to the right of the Debtors or Reorganized
Debtors to effect the Restructuring Transactions as provided in the Plan, (b)
cause any Debtor to be liable for any Impaired Claim or Unimpaired Claim under
the Plan, for which it otherwise is not liable and the liability of any Debtor
for any such Claim shall not be affected by such substantive consolidation, (c)
affect Intercompany Claims of Debtors against Debtors and (d) affect Interests
in the Debtors which are Subsidiaries of PSC. On the Effective Date, except as
specifically set forth in the Plan, the Intercompany Claims of Debtors against
Debtors shall be reinstated or discharged and satisfied, at the option of PSC or
PSI with the consent of the Required Lenders, by contributions, distributions or
otherwise. On the Effective Date, to the extent a Debtor which is a Subsidiary
is not dissolved or merged as part of the Restructuring Transactions, the
Interests in such Debtor shall remain outstanding.

C.       CLASSIFICATION AND TREATMENT OF CLAIMS AND INTERESTS

         Section 1123 of the Bankruptcy Code provides that a plan of
reorganization must classify the claims and interests of a debtor's creditors
and equity interest holders. In accordance with section 1123, the Plan divides
Claims and Interests into Classes and sets forth the treatment for each Class
(other than DIP Facility Claims, Administrative Claims and Priority Tax Claims
which, pursuant to section 1123(a)(1), do not need to be classified). The
Debtors also are required, under section 1122 of the Bankruptcy Code, to
classify Claims against and Interests in the Debtors into Classes that contain
Claims and Interests that are substantially similar to the other Claims and
Interests in such Class. The Debtors believe that the Plan has classified all
Claims and Interests in compliance with the provisions of section 1122, but it
is possible that a holder of a Claim or Interest may challenge the Debtors'
classification of Claims and Interests and that the Bankruptcy Court may find
that a different classification is required for the Plan to be confirmed. In
that event, the Debtors intend, to the extent permitted by the Bankruptcy Code,
the Plan and the Bankruptcy Court, to make such reasonable modifications of the
classifications under the Plan to permit confirmation and to use the Plan
acceptances received in this Solicitation for purposes of obtaining the approval
of the reconstituted Class or Classes of which each accepting holder ultimately
is deemed to be a member. Any such reclassification could adversely affect the
Class in which such holder initially was a member, or any other Class under the
Plan, by changing the composition of such Class and the vote required of that
Class for approval of the Plan. Furthermore, a reclassification of a Claim or
Interest after approval of the Plan could necessitate a resolicitation of
acceptances of the Plan.

         The amount of any Impaired Claim that ultimately is allowed by the
Bankruptcy Court may vary from any estimated allowed amount of such Claim and
accordingly the total Claims ultimately allowed by the Bankruptcy Court with
respect to each Impaired Class of Claims may also vary from any estimates
contained herein with respect to the aggregate Claims in any Impaired Class.
Thus, the value of the property that ultimately will be received by a particular
holder of an Allowed Claim under the Plan may be adversely or favorably affected
by the aggregate amount of Claims ultimately allowed in the applicable Class.
Additionally, distributions to holders of Claims in Classes 8B and 8C will
ultimately be determined by the number and amount of Allowed Claims in such
Classes as well as the number and amount of holders of Canadian Class 8B and 8C
Claims that execute the Canadian Proof of Claim and Election. There can be no
assurance that the actual aggregate amounts of Allowed Claims in Impaired
Classes will not materially exceed the aggregate amounts estimated by the
Debtors. Thus, no representation can be or is being made with respect to the
accuracy of the expected percentage recovery by the holder of an Allowed Claim
in any particular Class.

         The classification of Claims and Interests and the nature of
distributions to members of each Class are summarized below. The Debtors believe
that the consideration, if any, provided under the Plan to holders of Claims
and Interests reflects an appropriate resolution of their Claims and Interests,
taking into account the differing nature and priority (including applicable
contractual and statutory subordination) of such Claims and Interests and the
fair value of the Debtors' assets. In view of the deemed rejection by Class 9,
however, as set forth below, the Debtors will seek confirmation of the Plan
pursuant to the "cramdown" provisions of the Bankruptcy Code. Specifically,
section 1129(b) of the Bankruptcy Code permits confirmation of a Chapter 11 plan
in certain circumstances even if the plan has not been accepted by all impaired
classes of claims and interests. See Article II.O of the Disclosure


                                        5

Statement, entitled "Summary of the Plan of Reorganization -- Conditions to
Confirmation and/or Consummation." Although the Debtors believe that the Plan
could be confirmed under section 1129(b), there can be no assurance that the
requirements of such section would be satisfied.

         1.         Classified Claims and Interests

                    Under the Plan, classified Claims against and Interests in
the Debtors are divided into nine Classes (and three defined subclasses), and
are summarized in the following table.

CLASS 1 -   OTHER PRIORITY CLAIMS               Class 1 consists of all Claims entitled to priority pursuant to section 507(a)
                                                of the Bankruptcy Code other than DIP Facility Claims, Priority Tax Claims or
                                                Administrative Claims ("Other Priority Claims"). Under the Plan, on, or as soon as
                                                reasonably practicable after, the latest of (i) the Distribution Date, (ii) the
                                                date such Class 1 Other Priority Claim becomes an Allowed Class 1 Other Priority
                                                Claim, or (iii) the date such Class 1 Other Priority Claim becomes payable
                                                pursuant to any agreement between a Debtor and the holder of such Class 1 Other
                                                Priority Claim, each holder of an Allowed Class 1 Other Priority Claim will
                                                receive in full satisfaction, settlement, release and discharge of and in exchange
                                                for such Allowed Class 1 Other Priority Claim (a) Cash equal to the unpaid portion
                                                of such Allowed Class 1 Other Priority Claim or (b) such other treatment as to
                                                which a Debtor, with the consent of the Required Lenders, and such holder shall
                                                have agreed upon in writing.  Class 1 Other Priority Claims are Unimpaired and
                                                therefore not entitled to vote on the Plan.

CLASS 2 -   OTHER SECURED CLAIMS                Class 2 consists collectively of all Claims that are secured by a Lien upon
                                                property in which the Estate has an interest or that is subject to setoff under
                                                section 553 of the Bankruptcy Code, to the extent of the value of the Claim
                                                holders' interest in the Estate's interest in such property or to the extent of
                                                the amount subject to setoff, as applicable, as determined pursuant to section
                                                506(a) of the Bankruptcy Code ("Secured Claims") against the Reorganized Debtors
                                                other than the Secured Claims included in Class 6 below ("Other Secured Claims").
                                                Each holder of a Class 2 Other Secured Claim shall be treated as a separate class
                                                for all purposes under the Plan and the Bankruptcy Code, and each holder of an
                                                Allowed Class 2 Other Secured Claim will receive the treatment summarized below in
                                                Option A or B.  Under the Plan, except as to the Liens and security interests of
                                                the Account Intermediaries, the Debtors specifically reserve all rights to
                                                challenge the validity, nature and perfection of any purported liens and security
                                                interests of the holders of Other Secured Claims.

                                                         Option A: Allowed Class 2 Other Secured Claims with respect to which
                                                the applicable Debtor or the applicable Reorganized Debtor selects Option A,
                                                subject to the consent of the Required Lenders, will be paid in cash, in full,
                                                by the Reorganized Debtors,

                                                         Option B: Allowed Class 2 Other Secured Claims with respect to
                                                which the applicable Debtor or Reorganized Debtor selects Option B will be
                                                Reinstated.

                                                The applicable Debtor or Reorganized Debtor will be deemed to have elected Option
                                                B in respect of the Other Secured Claims of the Account Intermediaries and all
                                                other Allowed Class 2 Other Secured Claims except the other Allowed Class 2
                                                Secured Claims which the applicable Debtor or Reorganized Debtor, with the consent
                                                of the Required Lenders, elects Option A in writing prior to the Confirmation
                                                Hearing. Class 2 Other Secured Claims are Unimpaired and therefore not entitled to
                                                vote on the Plan.

CLASS 3 -   GENERAL UNSECURED CLAIMS            Class 3 consists of all Claims against the Debtors that are not DIP
                                                Facility Claims, Administrative Claims, Priority Tax Claims, Other Priority
                                                Claims, Other Secured Claims, Intercompany Claims of non- Debtors, Lender Claims,
                                                Impaired Unsecured Claims, Securities Claims, Other Securities Claims or Excluded
                                                Indemnification Obligations.  Under the Plan, each holder of an Allowed Class 3
                                                General Unsecured Claim shall, at the option of the Debtors, with the consent of
                                                the Required Lenders (a) have its Claim Reinstated or (b) receive such other
                                                treatment as to which the applicable Debtor or Reorganized Debtor and such holder
                                                shall have agreed upon in writing. Class 3 General Unsecured Claims are Unimpaired
                                                and therefore not entitled to vote on the Plan.

CLASS 4 -   INTERCOMPANY CLAIMS OF NON-         Class 4 consists of all intercompany claims of Non-Debtors (the
            DEBTORS                             "Intercompany Claims," as defined in the Plan).  Under the Plan, each
                                                holder of an Allowed Class 4 Intercompany Claim (except for the Intercompany
                                                Claims of Phencorp against PSI, Luntz Acquisition (Delaware) Corporation, and RESI
                                                Acquisition (Delaware) Corporation, in full satisfaction, settlement, release and
                                                discharge of and in exchange for such Allowed Class 4 Intercompany Claim, will, in
                                                the sole discretion of the applicable Debtor as Reorganized Debtor, with the
                                                consent of the Required Lenders (a) have its Claim Reinstated or (b) receive such
                                                other treatment as the applicable Debtor as Reorganized Debtor and such holder
                                                have agreed upon in writing. In the event the Canadian Reorganization Plan is not
                                                sanctioned and the Alternate Canadian Transactions are implemented, Phencorp will
                                                be liquidated and its receivables distributed to its sole shareholder, Philip
                                                Enterprises, Inc., which will in turn contribute the receivables as a capital
                                                contribution to its wholly-owned subsidiary, PSI. Phencorp has agreed to accept
                                                the Plan. Class 4 Intercompany Claims of Non-Debtors are Unimpaired and therefore
                                                not entitled to vote on the Plan.

                                                "Subsidiary Interests").  Under the Plan, subject to the Restructuring
                                                Transactions, all Class 5 Subsidiary Interests will be deemed Allowed Interests
                                                and Reinstated on the Effective Date, but the holders of Class 5 Subsidiary
                                                Interests shall receive no distribution under the Plan on account of such
                                                Interests; provided, however, if the Alternate Canadian Transactions are
                                                implemented, then the Interests in PSI and the Luntz Corporation owned by Philip
                                                Enterprises, Inc. shall be deemed cancelled and extinguished as of the Effective
                                                Date. Class 5 Subsidiary Interests are Unimpaired and therefore not entitled to
                                                vote on the Plan.

CLASS 6 -   SECURED LENDER CLAIMS               Class 6 consists of all Secured Claims of Lenders (the "Secured Lender
                                                Claims") arising under or as a result of the Pre-Petition Credit Agreement, the
                                                Credit Documents and the Lender Lock-up Agreement (the "Pre-Petition Credit
                                                Facility Agreements"). Under the Plan, regardless whether the Canadian
                                                Reorganization Plan is sanctioned or the Alternate Canadian Transactions are
                                                implemented or the Canadian Plan Condition is waived, on the Effective Date, the
                                                Pre-Petition Credit Facility Agreements shall be amended and restated by the
                                                Amended and Restated Term Credit Agreement without any further action by any
                                                party.

                                                Class 6 Additional Distribution. The holders of Unsecured Lender Claims shall be
                                                deemed to have waived any and all distributions to which they would be entitled
                                                under the Plan as holders of Unsecured Lender Claims, including the benefits of any
                                                and all contractual subordination provisions in respect of the Old Debentures and
                                                shall receive no distributions on account of such Unsecured Lender Claims; provided,
                                                however, that the holders of the Allowed Unsecured Lender Claims shall retain such
                                                Claims against PSC and the Subsidiaries other than the Debtors. If the holders of
                                                Allowed Class 7 Claims vote to reject the Plan, then the holders of such Claims
                                                shall not receive or retain any property on account of such Claims.

CLASS 8A -   OLD COMMON SHARES                  Class 8A consists of all Interests of holders of the common shares of
                                                PSC issued and outstanding as of the Petition Date (the "Old Common

                                                and in exchange for Class 8A Interests, holders of Allowed Class 8A Interests shall
                                                be entitled to (a) if the Canadian Reorganization Plan is sanctioned, retain their
                                                Old Common Shares, which after giving effect to the issuance of New Common Shares
                                                shall be two percent (2.0%) of the PSC Common Shares issued and outstanding as of
                                                the Effective Date (which shall equal 480,000 PSC Common Shares after giving effect
                                                to the Reverse Stock Split) subject to Dilution or (b) if the Alternate Canadian

                                                subject to Dilution.

                                                Notwithstanding any provision contained herein to the contrary, if Class 7 votes to
                                                reject the Plan, then the holders of Class 8A Interests shall not receive or retain
                                                any property on account of such Interests. In such case, the Reorganized Debtors
                                                will take all such corporate actions as are necessary or required on and after the
                                                Effective Date to cancel such Interests.

                                                If Class 7 votes to reject the Plan, then holders of Class 8B Claims shall not

                                                Stock Split), subject to Dilution.

                                                Treatment if the Alternate Canadian Transactions are Implemented: On or as soon as

                                                distribution to Class 8C.

                                                If Class 7 votes to reject the Plan, then holders of Class 8C Claims shall not
                                                receive or retain any property under the Plan. Class 8C Other Securities Claims are

                                                Securities shall be deemed cancelled and extinguished. Class 9 Interests are
                                                Impaired and will receive no distribution under the Plan and are therefore deemed to
                                                reject the Plan and are not entitled to vote on the Plan.

                    (a)     The Class 7 Election

                           Qualifying Class 7 Creditors are holders of Class 7
Impaired Unsecured Claims that, as of the Voting Deadline, are holders of
Allowed Impaired Unsecured Claims in a liquidated amount entitled to a
distribution. The Class 7 Election entitles Qualifying Class 7 Creditors to
elect to forgo their pro rata distribution of New Unsecured PIK Notes for New
Unsecured Convertible Notes (See Article VIII.E "New Debt and Securities to Be
Issued Under the Plan - New Unsecured Convertible Notes") subject to certain
terms and limitations. Qualifying Class 7 Creditors shall have the right to make
the Class 7 Election if Class 7 votes to accept the Plan. If Class 7

                                       13

votes to accept the Plan, Qualifying Class 7 Creditors electing
New Unsecured Convertible Notes shall receive, in exchange for every $1.00 in
face amount of New Unsecured PIK Notes that such Qualifying Class 7 Creditor
would have received under the Plan, $1.50 in face amount of New Unsecured
Convertible Notes. The aggregate of New Unsecured Convertible Notes shall not
exceed $18 million. Holders of Old Debentures that do not make an affirmative
Class 7 Election or that do not vote on the Plan shall be deemed to have elected
to receive the New Unsecured Convertible Notes. All other Qualifying Class 7
Creditors that do not make an affirmative Class 7 Election or that do not vote
on the Plan shall be deemed to have elected to receive the New Unsecured PIK
Notes.

                           If Qualifying Class 7 Creditors elect to convert more
than $12 million in aggregate face amount of New Unsecured PIK Notes into New
Unsecured Convertible Notes, then each Qualifying Class 7 Creditor shall be
entitled to its pro rata share of $18 million in face amount of New Unsecured
Convertible Notes (with such pro rata determination to include only Claims of
the Qualifying Class 7 Creditors electing the New Unsecured Convertible Notes),
and such holders shall be deemed not to have made the Class 7 Election with
respect to the balance of their Class 7 Claims.

                           On the Effective Date, the Old Debentures, the Old
Indenture and any agreement with respect to Impaired Unsecured Claims shall
be terminated automatically without any further action by any party and shall no
longer be of any force or effect, except that, as between the Indenture Trustee
and the holders of the Old Debentures, provisions relating to any
indemnification of the Indenture Trustee by the holders of Old Debentures, any
payment of the Indenture Trustee's compensation, expenses (including, but no
limited to, the Indenture Trustee's professional fees and expenses),
disbursements and advances, and for any lien prior to the claims of holders of
Old Debentures to secure such compensation, fees, expenses, disbursements and
advances, shall remain in full force and effect.

                           The following is a numerical example illustrating
the effect of a hypothetical Class 7 Election on distributions of New
Unsecured PIK Notes and New Unsecured Convertible Notes under the Plan, assuming
both Class 7 votes to accept the Plan and the class of holders of Canadian
Impaired Unsecured Claims votes to accept the Canadian Reorganization Plan. This
numerical example is provided for illustrative purposes only and is not a
prediction of any amount that actually will be used in making, or result from
making, any such calculation.

Hypothetical Numbers:

     (i)      Aggregate Allowed Amount of Class 7 Claims - $100,000,000


     (ii)     Aggregate Amount of Canadian Impaired Unsecured Claims -
              $30,000,000

     (iii)    Aggregate Amount of Allowed Class 7 Claims of Qualifying Creditors
              - $80,000,000

     (iv)     Aggregate Amount of Allowed Class 7 Claims of Qualifying Creditors
              electing New Unsecured Convertible Notes - $50,000,000

                           Under this hypothetical example, holders of Allowed
Class 7 Claims of Qualifying Creditors electing the New Unsecured Convertible
Notes are entitled to $23.07 million of New Unsecured PIK Notes. This amount is
determined by multiplying such creditors' pro rata share of aggregate Allowed
Amount of Class 7 Claims plus the aggregate Amount of Canadian Impaired
Unsecured Claims ($50 million divided by $130 million) by the maximum amount of
New Unsecured PIK Notes to be issued before taking into consideration the Class
7 Election ($60 million) ($50 million divided by $130 million x $60 million =
$23.07 million). However, such creditors have elected to forgo $12 million in
New Unsecured PIK Notes in favor of $18 million in New Unsecured Convertible
Notes. Therefore, such creditors have reduced their distribution of New
Unsecured PIK Notes to $11.07 million ($23.07 million - $12 million = $11.07
million). Such creditors would share pro rata as a group in $18 million of the
New Unsecured Convertible Notes (which would be in satisfaction of approximately
$26 million in Claims) and

                                       14

<PAGE>   25
 would also be entitled to have the balance of their Claims (approximately $24
million) share in the distribution of $11.07 million of New Unsecured PIK Notes.

                           Under the above-described hypothetical numerical
example, the holder of an Allowed Class 7 Claim in the amount of $3,000,000 that
is not a Qualifying Class 7 Creditor or a Qualifying Class 7 Creditor that does
not elect the Unsecured Convertible Notes in the Class 7 Election would receive
(i) 27,692 shares of PSC Common Shares (after giving effect to Reverse Stock
Split) (2.3% of the 1,200,000 PSC Common Shares) (2.3% = $3,000,000 divided by
$130,000,000) (2.3% x 1,200,000 = 27,692); and (ii) $1,384,875 in New Unsecured
PIK Notes. This amount of New Unsecured PIK Notes is determined as follows:
($130 million (aggregate Allowed Amount of Class 7 Claims plus aggregate Amount
of Canadian Impaired Unsecured Claims) - $50 million (aggregate Amount of
Allowed Class 7 Claims of Qualifying Creditors electing New Unsecured
Convertible Notes claims) = $80 million); such creditors' pro rata share of $80
million is $3 million/$80 million = .0375; .0375 x New Unsecured PIK Notes for
non-electing creditors ($36,930,000) ($48,000,000 - $11,070,000); .0375 x
$36,930,000 = $1,384,875.

                           Under the above-described hypothetical numerical
example, a holder of an Allowed Class 7 Claim in the amount of $3,000,000 that
is a Qualifying Class 7 Creditor and elects the New Unsecured Convertible Notes
will receive (i) 27,692 shares of PSC Common Shares (after giving effect to
Reverse Stock Split) (2.3% of the 1,200,000 PSC Common Shares) ($3,000,000
divided by $130,000,000) (2.3% x 1,200,000 = 27,692); (ii) $664,200 in New
Unsecured PIK Notes determined as follows: ($3,000,000 divided by $50,000,000=
 .06; .06 x New Unsecured PIK Notes for electing creditors ($11,070,000) =
$664,200); and (iii) $1,080,000 in New Unsecured Convertible Notes determined as
follows: $3,000,000 divided by $50,000,000 = .06; .06 x $18,000,000 =
$1,080,000.

                    (b)     Special Provision Regarding Unimpaired Claims

                           Except as otherwise provided in the Plan, nothing
shall affect the Debtors' or Reorganized Debtors' rights and defenses,
both legal and equitable, with respect to any Unimpaired Claims, including, but
not limited to, all rights with respect to legal and equitable defenses to
setoffs or recoupments against Unimpaired Claims. Notwithstanding the
substantive consolidation of the Debtors, the Unimpaired Claims of any
particular Debtor shall remain the obligations solely of such Debtor and shall
not become obligations of any other Debtor or Reorganized Debtor. Letters of
credit issued pursuant to the Pre-Petition Credit Agreement that remain
outstanding and undrawn on the Effective Date shall be replaced or, with the
consent of the issuers of such letters of credit, supported by letters of credit
issued under the Exit Facility.

                    (c)    Special Provision Regarding Canadian Class 8B and
Class 8C Holders

                           If the Alternate Canadian Transactions are
implemented, and in the event that a Canadian Class 8B or 8C Holder that
makes the U.S. Plan Election obtains an order of the Bankruptcy Court
determining that such claim is improperly classified or that such claim is not
subject to subordination pursuant to section 510(b) or 510(c) of the Bankruptcy
Code or disallowance pursuant to section 502(e)(1)(B) of the Bankruptcy Code,
such claim shall be deemed to be a Canadian Impaired Unsecured Claim that has
filed the Canadian Proof of Claim and Election. The Debtors shall have 30 days
to file objections to the Proof of Claim, if any. Only if no objection to the
Proof of Claim is filed within the required time period, including any
extensions granted by the Bankruptcy Court or agreed to by the Debtors and the
holder, or if the Bankruptcy Court enters an order allowing such a claim as
other than a subordinated claim, shall such claim be deemed an Allowed Canadian
Impaired Unsecured Claim that has filed the U.S. Plan Election. In no event
shall the holder of such Claim be a Qualifying Class 7 Creditor.

                    (d)    The U.S. Plan Election and Distributions on Account
Thereof

                           The Plan allows each holder of a Canadian Impaired
Unsecured Claim and each Canadian Class 8B or 8C Holder to make an election
to participate in the Plan by filing the Canadian Proof of Claim and Election
form. This election will only be effective if the Alternate Canadian
Transactions are implemented. By

                                       15

<PAGE>   26


executing the Canadian Proof of Claim and Election form, the Canadian
creditors (a) voluntarily and irrevocably elect to submit to the personal and
subject matter jurisdiction of the Bankruptcy Court for purposes of
participating in distributions under the Plan, (b) voluntarily and irrevocably
consent to have the allowance and priority of such holder's claim determined in
accordance with the provisions of the Bankruptcy Code, (c) voluntarily and
irrevocably agree to be bound by the provisions of the Plan in all respects and
(d) assert the amount of such holder's claim. A copy of the Canadian Proof of
Claim and Election shall be included in the solicitation materials distributed
to holders of Canadian Impaired Unsecured Claims and Canadian Class 8C Holders,
with a subsequent mailing being made to Canadian Class 8B Holders.

                           The U.S. Plan Election entitles such holder to
receive distributions as provided in Article III.F of the Plan if the
Alternate Canadian Transactions are implemented. If the Alternate Canadian
Transactions are implemented, any holder of an Allowed Canadian Impaired
Unsecured Claim that makes the U.S. Plan Election shall receive a distribution
of New Unsecured PIK Notes and Reorganized PSI Common Shares identical to that
which a holder of an Allowed Class 7 Claim of equal amount would be entitled. If
the Alternate Canadian Transactions are implemented, any Canadian Class 8B or 8C
Holder that make the U.S. Plan Election shall receive the distribution to which
such holder would be entitled pursuant to Article III.C.4 or III.C.5 of the
Plan, as applicable, if such holder's claim were a Class 8B or 8C Claim,
respectively. Any distribution to which a holder of a Canadian Impaired
Unsecured Claim or a Canadian Class 8B or 8C Holder is entitled under Article
III.F of the Plan is subject to the application of the provisions of the Plan
governing distributions generally and application of the provisions of the Plan,
the Bankruptcy Code and other laws of the United States regarding the
determination of allowance and priority of such claims.

                           If the Alternate Canadian Transactions are
implemented, the Lenders will enforce remedies available to them against
PSC and the other Canadian Debtors. The proceeds paid on the transfer of the
assets of PSC and the other Canadian Debtors will be distributed pursuant to the
priorities under Canadian law of the claims against such assets. Canadian
Impaired Unsecured Claims will not be compromised pursuant to the Alternate
Canadian Transactions, but it is expected that no distributions will be made to
the holders of such claims. The distributions that would have been made
available under the Canadian Reorganization Plan if the Canadian Reorganization
Plan had been sanctioned, for distribution to the holders of Canadian Impaired
Unsecured Claims that do not make the U.S. Plan Election, will instead comprise
the "Class 6 Additional Distribution" and be distributed to the holders of Class
6 Lender Claims pursuant to Article III.C.1 of the Plan. Holders of Canadian
Impaired Unsecured Claims entitled to receive a distribution pursuant to Article
III.F of the Plan shall not be entitled to vote on the Plan.

                    (e) Distributions to Classes 6, 7, 8B and 8C if Canadian
Plan Condition Is Waived

                           The Plan also provides the Debtors with the right
to waive the condition to the Plan's Effective Date that the Canadian
Reorganization Plan or Alternate Canadian Transactions be implemented by the
Effective Date. In such events, the Debtors may emerge from chapter 11 before
the outcome of the Canadian Cases has been determined. New Securities
distributed under the Plan will be issued by Reorganized PSI.

                           If the Canadian Plan Condition is waived,
distributions to holders of Claims in Classes 6 and 7 shall initially be
made pursuant to the provisions of Articles III.C.1.(b) and III.C.2.(b) of the
Plan, respec tively. If the Canadian Plan Condition is waived, an amount of New
Unsecured PIK Notes and the amount of Reorganized PSI Common Shares equivalent
to the amount of New Common Shares that would be distributed to the holders of
Canadian Impaired Unsecured Claims under the Canadian Reorganization Plan
(assuming all such Claims will be allowed) shall be held by the Disbursing Agent
pending the implementation of the Canadian Reorganization Plan or the Alternate
Canadian Transactions. If the Canadian Reorganization Plan is implemented, such
securities shall be deposited into the Disputed Distribution Reserve and shall
be distributed to holders of Allowed Class 7 Claims under the Plan and Allowed
Canadian Impaired Unsecured Claims in accordance with the Canadian
Reorganization Plan. If the Alternate Canadian Transactions are implemented,
such securities shall be distributed to

                                       16

<PAGE>   27

holders of Canadian Impaired Unsecured Claims that made the U.S. Plan
Election and to the holders of Class 6 Claims as the Class 6 Additional
Distribution pursuant to Articles III.F and III.C.1.(b) of the Plan
respectively, subject to the provisions of the Plan governing distributions
generally. The time, nature and amount of distributions to holders of Claims in
Classes 8B and 8C and Canadian Class 8B and 8C Holders that make the U.S. Plan
Election shall be determined upon the approval of the Canadian Reorganization
Plan or the Alternate Canadian Transactions, respectively.

         2.         Unclassified Claims

                    (a)    DIP Facility Claims (Unimpaired)

                           DIP Facility Claims consist of the Claims arising
under or as a result of the debtor-in- possession credit facility (the "DIP
Facility") provided to the Debtors during the Chapter 11 Cases, pursuant to the
credit agreement (the "DIP Facility Agreement"), between PSC and PSI as
borrowers, the Subsidiary Debtors and the Canadian Debtors as subsidiary
guarantors, Bankers Trust Company ("BTCo") as DIP agent, Canadian Imperial Bank
of Commerce ("CIBC") and BTCo as co-arrangers (the "DIP Co-Arrangers"), and
other various persons from time to time parties thereto. DIP Facility Claims are
Unimpaired under the Plan.

                           Under the Plan, on the Effective Date or the date
such DIP Facility Claim becomes payable pursuant to any agreement between
the Debtors and the holder of such DIP Facility Claim, each holder of an Allowed
DIP Facility Claim shall receive in full satisfaction, settlement, release and
discharge of and in exchange for such Allowed DIP Facility Claim (a) Cash equal
to the unpaid portion of such Allowed DIP Facility Claim or (b) such other
treatment as to which the Debtors, with the consent of the Required Lenders and
the Account Intermediaries, and such holder shall have agreed upon in writing.

                    (b)    Administrative Claims (Unimpaired)

                           The Plan provides that Administrative Claims are
Unimpaired. Administrative Claims consist of the actual and necessary costs
and expenses of the Chapter 11 Cases that are allowed under sections 503(b) and
507(a)(1) of the Bankruptcy Code. They include, among other things, the cost of
operating the Debtors' businesses following the Petition Date (e.g., the
post-petition salaries and other benefits for the Debtors' employees which the
Debtors have obtained an order allowing them to pay in the ordinary course of
business, post-petition rent, amounts owed to vendors providing goods and
services to the Debtors during the Chapter 11 Cases, tax obligations incurred
after the Petition Date, certain statutory fees and charges assessed under 28
U.S.C. ss. 1930) and the actual, reasonable fees and expenses of the
professionals retained by the Debtors and the creditors' committee. All payments
to professionals in connection with the Chapter 11 Cases for compensation and
reimbursement of expenses and all payments to reimburse expenses of members of
the creditors' committee would be made in accordance with the procedures
established by the Bankruptcy Code and the Bankruptcy Rules and would be subject
to approval of the Bankruptcy Court as being reasonable.

                           Except as otherwise provided in and subject to the
requirements of the Plan, the Plan provides that on, or as soon as
reasonably practicable after the latest of (i) the Distribution Date, (ii) the
date such Administrative Claim becomes an Allowed Administrative Claim, or (iii)
the date such Administrative Claim becomes payable pursuant to any agreement
between a Debtor and the holder of such Administrative Claim, each holder of an
Allowed Administrative Claim will receive in full satisfaction, settlement,
release and discharge of and in exchange for such Allowed Administrative Claim
(a) Cash equal to the unpaid portion of such Allowed Administrative Claim or (b)
such other treatment as to which the applicable Debtor, with the consent of the
Required Lenders, and such holder shall have agreed upon in writing; provided,
however, that Allowed Administra tive Claims with respect to liabilities
incurred by a Debtor in the ordinary course of business during the Chapter 11
Cases will be paid in the ordinary course of business in accordance with the
terms and conditions of any agreements relating thereto.


                                       17

<PAGE>   28
                           Holders of Administrative Claims based on liabilities
incurred by the Debtors in the ordinary course of their businesses will not be
required to file or serve any request for payment of such Claims, as these
liabilities will be assumed by the applicable Reorganized Debtor and paid,
performed or settled when due in accordance with the terms and conditions of the
particular agreements governing such obligations.

                           The Debtors therefore anticipate that Administrative
Claims against the Debtors will be paid as they come due during the Chapter 11
Cases and that the Administrative Claims after the Administrative Bar Date will,
for the most part, consist of the allowed but unpaid fees and expenses incurred
by professionals retained in the Chapter 11 Cases.

                    (c)    Priority Tax Claims (Unimpaired)

                           Priority Tax Claims are Unsecured Claims asserted by
federal and state governmental authorities for taxes specified in section
507(a)(8) of the Bankruptcy Code, such as certain income taxes, property taxes,
excise taxes, and employment and withholding taxes. These Unsecured Claims are
given a statutory priority in right of payment. The Plan provides that Priority
Tax Claims, if any, are Unimpaired.

                           Under the Plan, except to the extent that a holder of
an Allowed Priority Tax Claim has been paid by the Debtors prior to the
Distribution Date or has agreed in writing to a different treatment, each holder
of an Allowed Priority Tax Claim will be paid, at the sole discretion of the
Reorganized Debtors, (a) with the consent of the Required Lenders, Cash equal to
the unpaid portion of such Allowed Priority Tax Claim, (b) Cash payments over
time in an aggregate principal amount equal to the amount of such Allowed
Priority Tax Claim plus simple interest on the unpaid portion thereof at the
rate of seven percent (7%) per annum from the Effective Date through the date of
payment thereof, or (c) such other treatment as to which a Debtor, with the
consent of the Required Lenders, and such holder shall have agreed upon in
writing. Cash payments of principal will be made in annual installments equal to
ten percent (10%) of such Allowed Priority Tax Claim plus accrued and unpaid
interest, with the first payment to be due on or before the first anniversary of
the Effective Date, or as soon thereafter as is practicable, and subsequent
payments to be due on the anniversary of the first payment date or as soon
thereafter as is practicable; provided, however, that any installments remaining
unpaid on the date that is six years after the date of assessment of the tax
that is the basis for the Allowed Priority Tax Claim will be paid on the first
Business Day following such date, or as soon thereafter as is practicable
together with any accrued and unpaid interest to the date of payment; and
provided further that the Debtors reserve the right to pay any Allowed Priority
Tax Claim, or any remaining balance of any Allowed Priority Tax Claim, in full
at any time on or after the Distribution Date without premium or penalty; and
provided further that no holder of an Allowed Priority Tax Claim will be
entitled to any payments on account of any pre-Effective Date interest accrued
on or penalty arising after the Petition Date with respect to or in connection
with such Allowed Priority Tax Claim.

D.       EFFECT OF VOTING ON DISTRIBUTIONS

         1.         If the Canadian Reorganization Plan Is Sanctioned

                    If Class 7 votes to accept the Plan, then holders of Allowed
Class 6 Claims shall receive, along with other New Securities, 5,967,052,592
shares of New Common Shares, which shall be ninety-one percent (91%) of the PSC
Common Shares issued and outstanding as of the Effective Date, (which shall
equal 21,840,000 shares of the PSC Common Shares issued and outstanding as of
the Effective Date after giving effect to the Reverse Stock Split) in any case
subject to Dilution. Class 7 Claim holders will receive the distributions of New
Unsecured PIK Notes, New Unsecured Convertible Notes and New Common Shares, and
holders of Claims and Interests in Class 8 will receive or retain PSC Common
Shares, as described above.

                    Alternatively, if Class 7 votes to reject the Plan, then the
holders of an Allowed Class 6 Claims shall receive, along with other New
Securities, 22,800,000 shares of PSC Common Shares, which shall be ninety-

                                       18

<PAGE>   29

five percent (95%) of the PSC Common Shares issued and outstanding as of the
Effective Date, plus an amount of PSC Common Shares equivalent to the aggregate
amount of PSC Common Shares that would have been distributed to Class 7 (based
on the Debtors' estimate of the aggregate amount of Allowed Class 7 Claims),
subject to Dilution, (as well as an amount of New Unsecured PIK Notes equal to
the amount that would have been distributed to Class 7 had Class 7 voted to
accept the Plan (based on the Debtors' estimate of the aggregate amount of
Allowed Class 7 Claims)). Holders of Class 7 Claims will receive no
distributions under the Plan and no distributions will be made to Classes 8A, 8B
or 8C or to the holders of Canadian Impaired Unsecured Claims.

         2.         If the Alternate Canadian Transactions Are Implemented

                    If Class 7 votes to accept the Plan, then holders of Allowed
Class 6 Claims shall receive, along with other New Securities, ninety-one
percent (91%) which shall equal 21,840,000 shares of the Reorganized PSI Common
Shares as of the Effective Date, plus the Class 6 Additional Distribution (See
Article II.C "Summary of the Plan of Reorganization - - Classification and
Treatment of Claims and Interests - - The U.S. Plan Election and Distributions
on Account Thereof"), subject to Dilution. Class 7 Claim holders will receive
the distributions of New Unsecured PIK Notes, New Unsecured Convertible Notes
and New Common Shares, as described above. Such distributions will be shared
with holders of Canadian Impaired Unsecured Claims and Canadian Class 8B and 8C
Holders that make the U.S. Plan Election, as described above.

                    Alternatively, if Class 7 votes to reject the Plan, holders
of Allowed Class 6 Claims shall receive, along with other New Securities, one
hundred percent (100%) which shall equal 24,000,000 shares of the Reorganized
PSI Common Shares as of the Effective Date, subject to Dilution, and no New
Unsecured PIK Notes will be issued to any Claim holder. The holders of Allowed
Class 6 Secured Lender Claims shall retain such claims against PSC and security
interests in assets of PSC and the other Canadian Debtors retained and not
transferred in connection with the transactions pursuant to the terms of the
Alternate Canadian Transactions. Holders of Class 7 Claims will receive no
distributions under the Plan nor will Canadian creditors that make the U.S. Plan
Election, and no distributions will be made to Classes 8A, 8B or 8C.

E.       SUMMARY OF DEBT TO BE INCURRED AND SECURITIES TO BE ISSUED IN
         CONNECTION WITH THE PLAN

         The Debtors anticipate that they will finalize the material terms of a
new senior secured facility (the "Exit Facility") prior to the Confirmation
Date, pursuant to which the Reorganized Debtors would have access to sufficient
working capital to maintain their operations, as well as the operations of the
Subsidiaries. Pursuant to the Lender Lock-up Agreement, the credit availability
under the Exit Facility is anticipated to be approximately $125 million. The
Exit Facility would be secured by guaranties and charges over the accounts
receivable and inventory and, if required, substantially all other assets of
Reorganized PSC and its subsidiaries, senior to all other security including the
security for the New Senior Secured Term Debt. The Debtors anticipate that the
Exit Facility would be used to (a) fund repayment of the DIP Facility, (b)
provide short-term working capital needs, and (c) fund letters of credit within
a sub-limit of the Exit Facility. The maturity of the Exit Facility is
contemplated as two years from Plan implementation, but may be refinanced in
whole but not in part by a replacement facility with the same priority. The
parties continue to negotiate the terms of the Exit Facility, and there can be
no assurances that the terms of such a Facility will not differ materially from
the description in the Lender Lock-up Agreement or that the parties will be able
to reach a final agreement.

         1.         If the Canadian Reorganization Plan Is Implemented.

                    Pursuant to the Plan, on or prior to the Effective Date, PSC
shall issue New Common Shares, New Secured PIK Debt and depending upon the votes
of Class 7 on the Plan and the class of holders of Canadian Impaired Unsecured
Claims on the Canadian Plan, New Unsecured PIK Notes and, if Class 7 votes to
accept the Plan and a Qualifying Class 7 Creditor elects New Unsecured
Convertible Notes in the Class 7 Election, the New Unsecured Convertible Notes,
the principal terms of which are summarized below.

                    Pursuant to the Pre-Petition Credit Agreement, the Lenders
have a security interest in the proceeds from the sale of the assets of PSC and
its Subsidiaries. The proceeds from the sale of certain assets of PSC and its
Subsidiaries were held by CIBC, as Administrative Agent, for the benefit of the
Administrative Agent and the Lenders. Pursuant to a Proceeds Agreement, dated as
of April 5, 1999, between PSC, PSI (and each of the direct and indirect
subsidiaries of PSC) and CIBC and the Lenders (the "Proceeds Agreement"), as has
been supplanted by the provisions of that certain approved Stipulation and Order
Authorizing and Restricting Use of Cash Collateral and Granting Adequate
Protection of Secured Claims (the "Cash Collateral Order"), the Lenders agreed
to release up to $93,000,000 of net proceeds from the sale of certain assets of
PSC and its Subsidiaries to the Debtors in accordance with a budget approved by
the Lenders and subject to certain conditions. CIBC transferred the funds not
released prior to the Petition Date to BTCo, as agent under the DIP Facility, in
accordance with the Cash Collateral Order.

                    In the event of any sale of the U.S. Ferrous Division of the
Debtors (the "US Ferrous Division"), the proceeds of such sale as well as the
net proceeds from asset sales in excess of the $93,000,000 deposited into the
Proceeds Account, shall be maintained in a separate interest-bearing account
(the "Excess Proceeds Account") during the Chapter 11 Cases. On the Distribution
Date, funds held in the Excess Proceeds Account shall be divided between the
Reorganized Companies and the holders of the Secured Lender Claims. As set forth
in Article III.C of the Plan, on the Distribution Date, the holders of the Class
6 Secured Lender Claims will receive from any funds in the Excess Proceeds
Account (i) to the extent any funds in the Excess Proceeds Account represent the
net proceeds from any sale of the US Ferrous Division, sixty-six and two-thirds
percent (66 2/3%) of the first $200,000,000 of such funds, and (ii) seventy-five
percent (75%) of all other funds held in the Excess Proceeds Account.

                    On the Effective Date, the Reorganized Debtors (in existence
after giving effect to the Restructuring Transactions) and the other Restricted
Subsidiaries shall also enter into the New Guaranties to guaranty and secure the
New Senior Secured Term Debt and the New Secured PIK Debt.

PSC or any Subsidiary other than the Debtors from such claims or their security
interests against any assets of PSC or any Subsidiary other than the Debtors
retained and not transferred in connection with the Alternate Canadian
Transactions, provided further, however, any such claims the Lenders hold shall
be reduced by the value of any distributions the Lenders receive by the Lenders
pursuant to the Plan, provided, further, that this release in this clause (i)
shall not be given by any Account Intermediary who is a current Bank Account
Service Provider, (ii) the directors, officers and employees of the Debtors or
the Subsidiaries in each case as of the Petition Date (and in addition, those

the respective current and professionals of the entities in subclauses

Debtors) (including current and former officers, directors, employees,
shareholders and of the released professionals), acting in such capacity.

         Further, as of the Effective Date, all holders of Claims and Interests
will be deemed to have released all claims and causes of action (other than the
right to enforce the Debtor or the Reorganized Debtors' obligations under the
Plan and any agreement thereunder) arising from an event occurring on or prior
to the Effective Date relating to the Debtors, the Subsidiaries, the Reorganized
Debtors, the Chapter 11 Cases, the Lender Lock-up Agreement or the Plan against
(i) the Debtors, the Subsidiaries and the Reorganized Debtors, (ii) the Lenders

holders of Claims (other than the Lenders) and Interests are not deemed to have
released any non-Debtor third party other than the Lenders and those parties
explicitly listed in subsections (ii), (iii), (iv) and (v) above.

G.       TREATMENT OF DIRECTOR AND OFFICER INDEMNIFICATION OBLIGATIONS UNDER
         THE PLAN

         Pursuant to the Plan, indemnification obligations as to the Reorganized
Debtors' directors and officers are divided into two categories: Excluded
Indemnification Obligations and Assumed Indemnification Obligations. Excluded
Indemnification Obligations are (i) the obligations of the Debtors to indemnify
any current or former officers, directors or employees solely as to claims
actually asserted as of the Petition Date, or claims asserted after the Petition
Date in the following actions or in actions initiated after the Petition Date,
in each case arising out of or related to the same nucleus of operative facts
alleged in the following actions as of the Petition Date or when such actions
were filed: (A) the consolidated, putative class action entitled In re Philip
Services, Corp. Securities Litigation, 98 CV 835 (MBM), previously pending
against PSC in the United States District Court for the Southern District of New
York, and the putative class action entitled Menegon v. Philip Services Corp.,
et al., File No. 4166 CP 98 (Ontario Court, General Division), (B) the action
filed by a group of former shareholders of the Steiner-Liff Metals group of
companies on October 6, 1998, with the American Arbitration Association
captioned In re Liff Arbitration, Case No. 39 Y 1680012 98 and the litigation
styled Liff v. Chodos, Case No. 99 Civ. 1322 (dismissed and pending appeal), (C)
the actions filed by a group of former shareholders of the Southern-Foundry
Supply group of companies captioned Gary D. Chazen, Robert G. Chazen, Julius L.
Chazen and Ruth E. Chazen v. Philip Metals Inc., et al., Case No:99 Civ. 2797
(MBM) (S.D.N.Y.) (dismissed); and Stephen M. Chazen v. Philip Metals Inc.,
previously known as Philip Metals (Ohio) Inc., Philip Services Corp., Allen
Fracassi, and Robert Waxman, No: CV9801642, in the Circuit Court of Jefferson
County, Alabama (subsequently dismissed in favor of arbitration) and (D) the
action captioned Great Plains Trust Company and Kornitzer Capital Management,
Inc. v. Robert M. Christe, R.L. Nelson, Jr., T. Wayne Wren, Jr., Michael W.
Ramirez, David E. Fanta, James E. Rief, William L. Fiedler, Michael A. Baker,
John U. Clarke, Frank A. Rossi, Thomas J. Tierney and T. Michael Young, No.
1999-38771, in the District Court of Harris County, Texas; (ii) any claims for
reimbursement, contribution or indemnity that may be asserted by Robert Waxman,
Greg Madesker, Rik Barrese, Drew Luntz, Andrew Luntz and John Luntz; (iii) any
claims for reimbursement, contribution or indemnity asserted by present or
former professionals or advisors of the Debtors or Subsidiaries, including,
without limitation, Deloitte & Touche, any insurance brokers retained by the
Debtors, accountants, auditors, financial consultants, underwriters or attorneys
as to claims arising out of the matters alleged in the Securities Actions, the
Chazen Actions, the Liff Actions, the Great Plains Action, or in any
action initiated after the Petition Date based upon similar factual allegations
or alleging similar causes of action and any indemnification obligation of such
professionals or advisors of the kind described in section 510(b) of the
Bankruptcy Code or subject to subordination pursuant to section 510(c) of the
Bankruptcy Code and (iv) any reimbursement, contribution or indemnity
obligations to current or former directors or officers of any Debtor that are
more expansive than those contained in section 7.02 of PSC's bylaws or which are
not permissible under the applicable governing corporate statute of the
applicable Debtor; provided, however, that "Excluded Indemnification
Obligations" shall not impact the setoff rights, if any, of any party, and shall
not include Assumed Indemnification Obligations in connection with any
governmental, regulatory or enforcement investigation or action or Assumed
Indemnification Obligations to pay the reasonable defense costs of any
individual who was a director, officer or employee of a Debtor as of the
Petition Date in connection with any third party complaint or claim by Deloitte
& Touche against such officer, director or employee in connection with any
action commenced by the Debtors, the Reorganized Debtors or the Lenders against
Deloitte & Touche and/or Robert Waxman arising out of the same nucleus of
operative facts alleged in the Securities Actions, the Chazen Actions or the
Liff Actions.

         Assumed Indemnification Obligations are (i) the obligations of PSC
pursuant to section 7.02 of its bylaws to indemnify current and former directors
and officers, on the terms and subject to the limitations described therein, if
and to the extent that such indemnification is permissible under the Ontario
Business Corporations Act or such other applicable governing corporate statute
and (ii) the obligations of the Debtors other than PSC to indemnify current and
former directors and officers under their respective bylaws to the extent such
indemnification obligations are not more expansive than those of PSC under
section 7.02 of its bylaws if and to the extent such indemnification is
permissible under the applicable governing corporate statute of the applicable
Debtor; in each case, including any affirmative obligation of the Debtors to
indemnify current and former directors and officers in connection with any
governmental, regulatory or enforcement investigation or action and in each case
solely with respect to such officer

                                       25

<PAGE>   36


or director actions subsequent to becoming an officer or director of
PSC or of a direct or indirect subsidiary or affiliate of PSC. Assumed
Indemnification Obligations shall not include any Excluded Indemnification
Obligations.

                    Under the Plan, any Claim other than the Assumed
Indemnification Obligations against any Debtor for reimbursement, contribution,
indemnity or setoff that is subject to section 510(b) and/or 510(c) of the
Bankruptcy Code or related to or arising from the facts surrounding, allegations
or actions resulting in a Claim that is subject to section 510(b) and/or 510(c)
of the Bankruptcy Code, and any Excluded Indemnification Obligation, shall be
deemed rejected for all purposes under the Plan and shall be deemed disallowed
under the Plan upon entry of the Confirmation Order pursuant to section
502(e)(1)(B) of the Bankruptcy Code to the fullest extent permitted by law;
provided, however, to the extent that any such Claim is not so disallowed and
becomes an Allowed Claim against any Debtor, then such Allowed Claim shall be
treated as an Allowed Class 8C Claim pursuant to sections 510(b) and/or 510(c)
of the Bankruptcy Code.

                    Under the Plan, the Assumed Indemnification Obligations
shall be deemed assumed by the Reorganized Debtors as of the Effective Date
without any further action by any party and in the event the Alternate Canadian
Transactions are implemented or the Canadian Plan Condition is waived, the
Assumed Indemnification Obligations of PSC shall be deemed assumed by
Reorganized PSI.

                    Any and all rights of the directors and officers to the
proceeds of the Debtors' relevant directors and officers insurance policies
whether for Excluded Indemnification Obligations or Assumed Indemnification
Obligations will be unaffected by and survive the Chapter 11 Cases.

H.       POST-CONSUMMATION OPERATIONS OF THE DEBTORS

         1.         Continued Corporate Existence

                    Following confirmation and consummation of the Plan, subject
to the Restructuring Transactions, each of the Debtors and the other
Subsidiaries will continue to exist as separate corporate entities in accordance
with the laws of their respective states of incorporation and pursuant to their
respective certificates or articles of incorporation and bylaws in effect prior
to consummation, except (i) to the extent such certificates or articles of
incorporation and bylaws are amended under the Plan or (ii) if the Canadian
Reorganization Plan is sanctioned, Reorganized PSC, with the consent of the
Required Lenders, may be continued under the laws of the Province of New
Brunswick, which continuance is expressly authorized by the Plan, or if the
Alternate Canadian Transactions are implemented, PSC is subject to the Alternate
Canadian Transactions. The certificate or articles of incorporation and bylaws
of each of the Debtors will be amended as necessary to satisfy the provisions of
the Plan and the Bankruptcy Code and will include, among other things, pursuant
to section 1123(a)(6) of the Bankruptcy Code, a provision prohibiting the
issuance of non-voting equity securities, but only to the extent required by
section 1123(a)(6) of the Bankruptcy Code.

                    Except as otherwise provided in the Plan, nothing shall
affect the Debtors' rights and defenses both legal and equitable, with respect
to any Unimpaired Claims, including, but not limited to, all rights with respect
to legal and equitable defenses to setoff or recoupments against Unimpaired
Claims. Notwithstanding the limited substantive consolidation of the Debtors
under the terms of the Plan, the Unimpaired Claims of any particular Debtor
shall remain the obligations solely of such Debtor and shall not become
obligations of any other Reorga nized Debtor.

         2.         Revesting of Assets

                    Pursuant to section 1141(b) of the Bankruptcy Code, all
property of each Debtor's Estate, together with any property of each Debtor that
is not property of its Estate and that is not specifically disposed of pursuant
to the Plan, shall revest in the applicable Reorganized Debtor on the Effective
Date. Thereafter, the

                                       26

<PAGE>   37


Reorganized Debtors may operate their businesses and may use, acquire
and dispose of property free of any restrictions of the Bankruptcy Code, the
Bankruptcy Rules and the Bankruptcy Court. As of the Effective Date, all
property of each Reorganized Debtor shall be free and clear of all Liens, Claims
and Interests, except as specifically provided in the Plan or the Confirmation
Order. Without limiting the generality of the foregoing, each Reorganized Debtor
may, without application to or approval by the Bankruptcy Court, pay fees that
it incurs after the Effective Date for professional services and expenses.

                    Notwithstanding anything to the contrary set forth in the
foregoing paragraph, if the Alternate Canadian Transactions are implemented then
the vesting of the property of PSC shall occur pursuant to the Alternate
Canadian Transactions and any order of the Canadian Bankruptcy Court or other
applicable Canadian Court.

                    On the Effective Date, if the Alternate Canadian
Transactions are implemented, PSC, the other Canadian Debtors and PSI shall take
any and all steps necessary on their part to implement the Alternate Canadian
Transactions and the Lenders shall retain all of their rights as secured
creditors with respect to any assets that remain in PSC or the other Canadian
Subsidiaries. PSC, PSI and the Reorganized Debtors are expressly authorized to
take any and all steps necessary to implement the Alternate Canadian
Transactions, including without limitation, PSC obtaining approval of the
Alternate Canadian Transactions by the Canadian Bankruptcy Court, entering into
any and all agreements necessary on their part to effectuate the Alternate
Canadian Transactions, and directing the other Canadian Debtors to obtain
approval of the Alternate Canadian Transactions by the Canadian Bankruptcy Court
and to enter into any and all agreements necessary to effectuate the Alternate
Canadian Transactions. The automatic stay of section 362(a) of the Bankruptcy
Code shall be deemed lifted on the Date so that the Alternate Canadian
Transactions may be effectuated to permit any required notices to be issued
or proceedings to be taken which be necessary so that the transfers of
assets pursuant to the Alternate Transactions may be made in compliance with
applicable law.

I.       DISTRIBUTIONS UNDER THE PLAN

         Reorganized PSC (if the Canadian Reorganization Plan is sanctioned),
Reorganized PSI (if the Alternate Canadian Transactions are implemented or the
Canadian Plan Condition is waived) or their authorized Disbursing Agent shall
make all distributions required under the Plan (subject to the provisions of
Articles III, VII and IX of the Plan). Distributions provided for in the Plan on
account of Allowed Old Debenture Claims shall be made to the indenture trustee,
as Disbursing Agent for Old Debenture Claims, for distribution to holders of
Allowed Old Debenture Claims. Any such further distributions shall be made
pursuant to the Old Indenture and the Plan, particularly to the Indenture
Trustee (i) to itself as Indenture Trustee for application of any unpaid fees,
compensation, expenses (including the Indenture Trustee's professional fees and
expenses) disbursements and advances; (ii) to itself as escrow agent holding an
expense fund of approximately $92,000 (such amount determined exclusively by the
Indenture Trustee) for the Great Plains Action, and thereafter (iii) on account
of Allowed Claims of holders of Old Debentures.

         If the Disbursing Agent is an independent third party designated by the
Reorganized Debtors to serve in such capacity, such Disbursing Agent shall
receive, without further Bankruptcy Court approval, reasonable compensation for
distribution services rendered pursuant to the Plan and reimbursement of
reasonable out-of-pocket expenses incurred in connection with such services from
the Reorganized Debtors on terms acceptable to the Reorganized Debtors. No
Disbursing Agent shall be required to give any bond or surety or other security
for the performance of its duties unless otherwise ordered by the Bankruptcy
Court.

         Cash payments made pursuant to the Plan will be in U.S. funds for
creditors located in the United States and in Canadian funds for creditors
located in Canada, unless such creditors in Canada have previously agreed, or
contracted for, payment in U.S. funds, by means agreed to by the payor and the
payee, including by check or wire transfer, or, in the absence of an agreement,
such commercially reasonable manner as the payor shall determine in its sole
discretion.

                                       27

<PAGE>   38

         Except as otherwise provided in the Plan, any ancillary documents
entered into in connection therewith, or the Confirmation Order, the Debtors,
with the consent of the Required Lenders, shall have the right to prepay,
without penalty, all or any portion of an Allowed Claim at any time; provided,
however, that any such prepayment shall not violate, or otherwise prejudice, the
relative priorities among the classes of Claims.

         On the Effective Date, Reorganized PSC (if the Canadian Reorganization
Plan is sanctioned) or Reorganized PSI (if the Alternate Canadian Transactions
are implemented or the Canadian Plan Condition is waived) shall issue or
distribute in accordance with the provisions of the Plan all of the New Secured
PIK Debt, New Unsecured PIK Notes, New Unsecured Convertible Notes and New
Common Shares. On the Effective Date, Reorganized PSC shall take all steps to
provide that holders of Allowed Class 6 Claims are the holders of record on the
Effective Date of the New Common Shares to be distributed to such holders under
the Plan.

         1.         Distributions for Claims Allowed as of the Effective Date

                    (a)    Distribution Date

                           Except as otherwise provided herein or as ordered by
the Bankruptcy Court, distributions to be made on account of Claims that are
Allowed Claims as of the Effective Date shall be made not later than the
Distribution Date. Distributions on account of Claims that first become Allowed
Claims after the Effective Date shall be made pursuant to Articles III, VII and
IX of the Plan. Notwithstanding the date on which any distribution of securities
is actually made to a holder of a Claim or Interest that is an Allowed Claim or
Allowed Interest on the Effective Date, as of the date of the distribution such
holder shall be deemed to have the rights of a holder of such securities
distributed as of the Effective Date.

                    (b)    Record Date for Distributions to Holders of Lender
                           Claims and Old Debentures

                           At the close of business on the Distribution Record
Date, the transfer records for the Old Debentures and Lender Claims shall be
closed, and there shall be no further changes in the record holders of the Old
Debentures or Lender Claims. The Reorganized Debtors, the Disbursing Agent, and
the Administrative Agent for the Lenders shall have no obligation to recognize
any transfer of such Old Debentures or Lender Claims occurring after the
Distribution Record Date and shall be entitled instead to recognize and deal for
all purposes hereunder with only those record holders as of the close of
business on the Distribution Record Date.

                    (c)    Calculation of Distribution Amounts of New Common
                           Shares

                           No fractional shares of New Common Shares or
Reorganized PSI Common Shares shall be issued or distributed under the Plan.
Each Person entitled to receive New Common Shares will receive the total number
of whole shares of New Common Shares or Reorganized PSI Common Shares to which
such Person is entitled. Whenever any distribution to a particular Person would
otherwise call for distribution of a fraction of a share of New Common Shares or
Reorganized PSI Common Shares, the actual distribution of shares of such stock
shall be rounded to the next higher or lower whole number as follows: (a)
fractions 1/2 or greater shall be rounded to the next higher whole number, and
(b) fractions of less than 1/2 shall be rounded to the next lower whole number.
The total number of shares of New Common Shares to be distributed to a Class of
Claims or Interests shall be adjusted as necessary to account for the rounding
provided for in Article VII.F of the Plan. No consideration shall be provided in
lieu of fractional shares that are rounded down.

                    (d)    Calculation of Distribution Amounts of New Debt
                           Securities

                           Notwithstanding any other provision of the Plan, New
Debt Securities, other than the New Secured PIK Debt, will be issued in primary
denominations of $1,000 and such fractions thereof as necessary.

                                       28

<PAGE>   39

                    (e)    Delivery of Distributions

                           Distributions to holders of Allowed Claims shall be
made by the Disbursing Agent (a) at the addresses set forth on the Proofs of
Claim filed by such holders (or at the last known addresses of such holders if
no Proof of Claim is filed or if the Debtors have been notified of a change of
address), (b) at the addresses set forth in any written notices of address
changes delivered to the Disbursing Agent after the date of any related Proof of
Claim, (c) at the addresses reflected in the Schedules if no Proof of Claim has
been filed and the Disbursing Agent has not received a written notice of a
change of address, (d) in the case of the holder of an Allowed Old Debenture
Claim, at the addresses contained in the official records of the Indenture
Trustee under the Old Indenture, or (e) at the addresses set forth in a properly
completed letter of transmittal accompanying securities properly remitted to the
Debtors. If any holder's distribution is returned as undeliverable, no further
distributions to such holder shall be made unless and until the Disbursing Agent
is notified of such holder's then current address, at which time all missed
distributions shall be made to such holder without interest. No undeliverable
distributions will go back to the Reorganized Debtors. All claims for
undeliverable distributions in respect of Allowed Class 7 Claims (or Canadian
Impaired Unsecured Claims for which the U.S. Plan Election is made if the
Alternate Canadian Transactions are implemented) must be made on or before the
expiration of the eighteenth (18th) month following the Effective Date, after
which date all unclaimed property shall be distributed pro rata to the holders
of the other Allowed Class 7 Claims (and Canadian Impaired Unsecured Claims for
which the U.S. Plan Election is made if the Alternate Canadian Transactions are
implemented) and the claim of any holder or successor to such holder with
respect to such property shall be discharged and forever barred, notwithstanding
any federal or state escheat laws to the contrary. Nothing contained in the Plan
shall require the Debtors, Reorganized Debtors, any Disbursing Agent or the
Indenture Trustee to attempt to locate any holder of an Allowed Claim or Allowed
Interest. All distributions pursuant to the Plan shall be at the Reorganized
Debtors' expense.

                    (f)    Notes and Old Debentures

                           Except as provided in the Plan for lost, stolen,
mutilated or destroyed notes or Old Debentures, each holder of an Allowed Claim
evidenced by a note or Old Debenture shall tender such note or Old Debenture to
the Disbursing Agent in accordance with written instructions to be provided in a
letter of transmittal to such holders by the Disbursing Agent as promptly as
practicable following the Effective Date. Such letter of transmittal shall
specify that delivery of such notes or Old Debentures will be effected, and risk
of loss and title thereto will pass, only upon the proper delivery of such notes
or Old Debentures with the letter of transmittal in accordance with such
instructions. Such letter of transmittal shall also include, among other
provisions, customary provisions with respect to the authority of the holder of
the applicable note or Old Debenture to act and the authenticity of any
signatures required on the letter of transmittal. All surrendered notes and Old
Debentures shall be marked as canceled and delivered to the Reorganized Debtors.

                    (g)    Lost, Mutilated or Destroyed Notes or Old Debentures

                           In addition to any requirements under the applicable
certificate or articles of incorpora tion or bylaws of the applicable Debtor,
any holder of a Claim or an Interest evidenced by a note or Old Debenture that
has been lost, stolen, mutilated or destroyed shall, in lieu of surrendering
such note or Old Debenture, deliver to the Disbursing Agent (a) evidence
satisfactory to the Disbursing Agent of the loss, theft, mutilation or
destruction; and (b) such indemnity as may be required by the Disbursing Agent
to hold the Disbursing Agent harmless from any damages, liabilities or costs
incurred in treating such individual as a holder of a note or Old Debenture.
Upon compliance with Article VII.H.2 of the Plan by a holder of a Claim or an
Interest evidenced by a note or Old Debenture, such holder shall, for all
purposes under the Plan, be deemed to have surrendered a note or Old Debenture,
as applicable.

<PAGE>   40

                    (h)    Failure to Surrender Canceled Note or Old Debentures

                           Any holder of a note or Old Debenture that fails to
surrender or be deemed to have surrendered such note or Old Debenture on or
before the second anniversary of the Effective Date shall have its claim for a
distribution pursuant to the Plan on account of such note or Old Debenture
discharged and shall be forever barred from asserting any such claim against any
Reorganized Debtor or their respective property.

                    (i) Distribution to Holders of Class 8 Claims and Interests

                           A description of the procedure for the distribution
to holders of Class 8 Claims and Interests, as well as the procedure for the
establishment of a reserve for the benefit of holders of Disputed Class 8 Claims
and Interests, if any, after such Claims or Interests become Allowed Claims or
Interests will be included in the Plan Supplement.

         2.         Resolution and Treatment of Disputed, Contingent, and
                    Unliquidated Claims and Disputed Interests

                    (a)    Prosecution of Objections

                           After the Confirmation Date, only the Debtors, the
Reorganized Debtors (subject to Article XIV.G of the Plan), the Creditors'
Committee and the Indenture Trustee shall have the authority to file objections,
settle, compromise, withdraw or litigate to judgment objections to Claims (and
Canadian Impaired Unsecured Claims the holders of which have made the U.S. Plan
Election if the Alternate Canadian Transactions are implemented) and Interests.
From and after the Effective Date, the Reorganized Debtors may settle or
compromise any Disputed Class 7 Claim, Disputed Canadian Impaired Unsecured
Claim the holder of which has made the U.S. Plan Election if the Alternate
Canadian Transactions are implemented or Disputed Interest, without approval of
the Bankruptcy Court.

                    (b)    No Distributions Pending Allowance

                           Notwithstanding any other provision of the Plan, no
payments or distributions shall be made with respect to all or any portion of a
Disputed Class 7 Claim or Disputed Canadian Impaired Unsecured Claim unless and
until some portion thereof has become an Allowed Claim or Allowed Canadian
Impaired Unsecured Claim, respectively.

                    (c)    Disputed Distribution Reserve; Reserve for Subsequent
                           Distributions to Qualifying Class 7 Creditors

                           On the Effective Date (or as soon thereafter as is
practicable) if holders of Allowed Class 7 Claims are to receive distributions
in accordance with Article III.C, the Disbursing Agent shall establish the
Disputed Distribution Reserve by withholding from the initial distribution on
account of Allowed Class 7 Claims, Allowed Canadian Impaired Unsecured Claims
and the Class 6 Additional Distribution (as applicable) an amount of New
Unsecured PIK Notes and New Common Shares (or Reorganized PSI Common Shares as
applicable) calculated as if all Class 7 Claims and Canadian Impaired Unsecured
Claims were Allowed Class 7 Claims and Allowed Canadian Impaired Unsecured
Claims as of such date, in an amount equal to one hundred percent (100%) of
their Disputed Class 7 and Disputed Canadian Impaired Unsecured Claim Amount.
The Disbursing Agent shall also establish a reserve for subsequent distributions
to Qualifying Class 7 Creditors containing the maximum amount of New Unsecured
Convertible Notes distributable under the Plan, if necessary, less the amount of
New Unsecured Convertible Notes distributed to Qualifying Class 7 Creditors on
the Distribution Date.

                    (d)    Distributions After Allowance of Class 7 Claims and
                           Canadian Impaired Unsecured Claims

                           The Disbursing Agent shall make payments and
distributions from the Disputed Distribution Reserve to each holder of a
Disputed Class 7 Claim that has become an Allowed Class 7 Claim and each holder
of a Disputed Canadian Impaired Unsecured Claim that has become an Allowed
Canadian Impaired Unsecured Claim, in each case in accordance with the
provisions of the Plan or the Canadian Reorganization Plan, respectively. On the
next succeeding interim distribution date after the date that the order or
judgment of the Bankruptcy Court or the Canadian Bankruptcy Court allowing such
Claim or claim becomes a Final Order, the Disbursing Agent shall distribute to
the holder of such Claim or claim any New Unsecured PIK Notes and New Common
Shares (or Reorganized PSI Common Shares, as applicable) in the Disputed
Distribution Reserve that would have been distributed on the Distribution Date
had such Claim been an Allowed Class 7 Claim or an Allowed Canadian Impaired
Unsecured Claim on the Distribution Date. After a Final Order has been entered,
or other final resolution has been reached, with respect to each of the Disputed
Class 7 Claims and Disputed Canadian Impaired Unsecured Claims, any New
Unsecured PIK Notes, New Unsecured Convertible Notes, and New Common Shares or
Reorganized PSI Common Shares that remain in the Disputed Distribution Reserve
and the reserve for subsequent distributions to Qualifying Class 7 Creditors
shall be distributed, as applicable, pro rata to holders of (i) Allowed Claims
in Class 7, (ii) Allowed Canadian Impaired Unsecured Claims and (iii) holders of
the Class 6 Secured Lender Claims on account of the Class 6 Additional
Distribution, if applicable (based on an estimate of the allowed Canadian
Impaired Unsecured Claims of holders who did not make the U.S. Plan Election);
provided however, that only Qualifying Class 7 Creditors shall be entitled to
receive distributions of New Unsecured Convertible Notes from the reserve for
subsequent distributions to Qualifying Class 7 Creditors. All distributions made
under Article IX.D of the Plan on account of an Allowed Class 7 Claim and
Allowed Canadian Impaired Unsecured Claim, shall be made together with any
payments or other distributions made on account of, as well as any obligations
arising from, the distributed property, as if such Allowed Class 7 Claim or
Allowed Canadian Impaired Unsecured Claim had been an Allowed Class 7 Claim or
Allowed Canadian Impaired Unsecured Claim on the Distribution Date.
Notwithstanding the foregoing, the Disbursing Agent shall not be required to
make distributions under Article IX.D more frequently than once every 180 days
or to make any individual payments in an amount less than $25.00.
Notwithstanding anything herein to the contrary, if the Canadian Reorganization
Plan is sanctioned, disbursements to holders of Canadian Impaired Unsecured
Claims shall be made in compliance with the Canadian Reorganization Plan.

                    (e)    Distributions Procedures for Class 8 Claims and
                           Interests

                           A description of the procedure for the distribution
to holders of Class 8 Claims and Interests, as well as the procedure for the
establishment of a reserve for the benefit of holders of Class 8 Claims and
Interests that have not become Allowed, if any, and the procedure for
distribution to holders of Class 8 Claims and Interests that have not become
Allowed, if any, after such Claims or Interests, become Allowed Claims or
Interests will be included in the Plan Supplement.

J.       OTHER MATTERS

         1.         Treatment of Executory Contracts and Unexpired Leases

                    Under section 365 of the Bankruptcy Code, the Debtors have
the right, subject to Bankruptcy Court approval, to assume or reject any
executory contracts or unexpired leases. If the Debtors reject an executory
contract or unexpired lease that was entered into before the Petition Date, the
contract or lease will be treated as if it had been breached on the date
immediately preceding the Petition Date, and the other party to the agreement
will have an Impaired Unsecured Claim for damages incurred as a result of the
rejection. In the case of rejection of employment severance agreements and real
property leases, damages are subject to certain limitations imposed by sections
365 and 502 of the Bankruptcy Code.

                                       31

<PAGE>   42


                    (a)    Assumed Contracts and Leases; Related Payments

                           Except as otherwise provided in the Plan, or in any
contract, instrument, release, indenture or other agreement or document entered
into in connection with the Plan, as of the Effective Date each of the Debtors
will be deemed to have assumed each executory contract and unexpired lease to
which it is a party, unless such contract or lease (i) was previously assumed or
rejected by one of the Debtors, (ii) previously expired or terminated pursuant
to its own terms, or (iii) as otherwise set forth in the schedule to be provided
in the Plan Supplement as being an executory contract or unexpired lease to
reject which schedule shall be included in the Plan Supplement, provided
however, that the Debtors reserve their right, at any time prior to the
Confirmation Date, to amend the schedule to be provided in the Plan Supplement
to delete an unexpired lease or executory contract therefrom or add any
unexpired lease or executory contract thereto. The Confirmation Order will
constitute an order of the Bankruptcy Court under section 365 of the Bankruptcy
Code approving the contract and lease assumptions described above, as of the
Effective Date.

                           Each executory contract and unexpired lease that is
assumed and relates to the use, ability to acquire, or occupancy of real
property will include (a) all modifications, amendments, supplements,
restatements, or other agreements made directly or indirectly by any agreement,
instrument, or other document that in any manner affect such executory contract
or unexpired lease and (b) all executory contracts or unexpired leases
appurtenant to the premises, including all easements, licenses, permits, rights,
privileges, immunities, options, rights of first refusal, powers, uses,
usufructs, reciprocal easement agreements, vaults, tunnel or bridge agreements
or franchises, and any other interests in real estate or rights in rem related
to such premises, unless any of the foregoing agreements has been rejected
pursuant to an order of the Bankruptcy Court or is the subject of a motion to
reject filed on or before the Confirmation Date.

                           Any monetary amounts by which each executory contract
and unexpired lease to be assumed pursuant to the Plan is in default will be
satisfied, under section 365(b)(1) of the Bankruptcy Code, at the option of the
Debtors, or an assignee of the Debtors assuming such contract or lease, by Cure.
If there is a dispute regarding (i) the nature or amount of any Cure, (ii) the
ability of a Reorganized Debtor or any assignee to provide "adequate assurance
of future performance" (within the meaning of section 365 of the Bankruptcy
Code) under the contract or lease to be assumed, or (iii) any other matter
pertaining to assumption, Cure will occur following the entry of a Final Order
resolving the dispute and approving the assumption or assumption and assignment,
as the case may be.

                    (b)    Rejected Contracts and Leases; Bar to Rejection
                           Damages

                           Except as otherwise provided in the Plan and subject
to Article VIII.A thereof or as otherwise provided in any contract, instrument,
release, indenture or other agreement or document entered into in connection
with the Plan, none of the executory contracts and unexpired leases to which the
Debtors, or any of them, are a party shall be rejected under the Plan.

                    (c)    Compensation and Benefit Programs

                           Except and to the extent previously assumed or
rejected by an order of the Bankruptcy Court on or before the Confirmation Date,
all employment agreements and employee compensation and benefit programs of the
Debtors, including programs subject to sections 1114 and 1129(a)(13) of the
Bankruptcy Code, entered into before or after the Petition Date and not since
terminated, shall be deemed to be, and shall be treated as though they are,
executory contracts that are assumed under Article VIII.A of the Plan and in the
event the Alternate Canadian Transactions are implemented or the Canadian Plan
Condition is waived, assumed and assigned to PSI, except for (i) executory
contracts or plans specifically rejected pursuant to the Plan (to the extent
such rejection does not violate sections 1114 and 1129(a)(13) of the Bankruptcy
Code) and (ii) executory contracts or plans as have previously been rejected,
are the subject of a motion to reject, or have been specifically waived by the
beneficiaries

                                       32

<PAGE>   43

of any plans or contracts; provided, however, that Debtors' obligations, if
any, to pay all "retiree benefits" as defined in 1114(a) of the Bankruptcy
Code shall continue.

         2.         Administrative Claims

                           The Confirmation Order will establish an
Administrative Claims Bar Date for filing of Administrative Claims that have not
been paid, released or otherwise settled (excluding Administrative Claims
arising from the sale of goods or services to a Debtor, after the Petition Date,
in the ordinary course of business), including Substantial Contribution Claims
(but not including claims for Professional Fees or the expenses of the members
of any creditors' committee), which date will be 45 days after the Confirmation
Date. Holders of asserted Administrative Claims, other than claims for
Professional Fees or the expenses of the members of any creditors' committee,
not paid prior to the Confirmation Date must submit proofs of Administrative
Claim on or before such Administrative Claims Bar Date or forever be barred from
doing so. The notice of Confirmation to be delivered pursuant to Fed. R. Bankr.
P. 3020(c) and 2002(f) will set forth such date and constitute notice of this
Administra tive Claims Bar Date. The Debtors or Reorganized Debtors, as the case
may be, shall have 45 days (or such longer period as may be allowed by order of
the Bankruptcy Court) following the Administrative Claims Bar Date to review and
object to such Administrative Claims before a hearing for determination of
allowance of such Administrative Claims.

         3.         Professional Fee Claims

                    All final requests for compensation or reimbursement of
Professional Fees pursuant to sections 327, 328, 330, 331, 503(b) or 1103 of the
Bankruptcy Code for services rendered to the Debtors or any creditors' committee
prior to the Effective Date (other than Substantial Contribution Claims under
section 503(b)(4) of the Bankruptcy Code) must be filed and served on the
Reorganized Debtors and their counsel no later than 45 days after the Effective
Date, unless otherwise ordered by the Bankruptcy Court. Objections to
applications of such Professionals or other entities for compensation or
reimbursement of expenses must be filed and served on the Reorganized Debtors
and their counsel and the requesting Professional or other entity no later than
45 days (or such longer period as may be allowed by order of the Bankruptcy
Court) after the date on which the applicable application for compensation or
reimbursement was served.

         4.         Interest on Claims

                    Interest and fees and expenses, if any, with respect to
Class 2 Other Secured Claims, shall be paid when due under the contract,
agreement, or other instrument governing the terms and conditions of the
obligation comprising such Allowed Claim, together with any additional amounts
required to be paid with respect to Unimpaired Claims pursuant to section 1124
of the Bankruptcy Code. Except as otherwise specifically provided for in the
Plan or Confirmation Order, or required by applicable bankruptcy law or an order
of the Bankruptcy Court, no holder of an Allowed Claim that is not an Other
Secured Claim will be entitled to interest accruing on or after the Petition
Date on account of such Claim for any purpose. In addition, interest will
neither accrue nor be paid upon any Disputed Claim in respect to the period from
the Petition Date to the date a final distribution is made thereon if and after
such Disputed Claim becomes an Allowed Claim.

         5.         Withholding and Reporting Requirements

                    In connection with the Plan and all distributions hereunder,
the Disbursing Agent shall, to the extent applicable, comply with all tax
withholding and reporting requirements imposed by any federal, state,
provincial, local or foreign taxing authority, and all distributions hereunder
shall be subject to any such withholding and reporting requirements. The
Disbursing Agent shall be authorized to take any and all actions that may be
necessary or appropriate to comply with such withholding and reporting
requirements. Notwithstanding any other provision of the Plan (i) each holder of
an Allowed Claim or Interest that is to receive a distribution of New

                                       33

<PAGE>   44


Securities to the Plan shall have sole and exclusive responsibility for the
satisfaction and payment of any tax obligations imposed by any governmental
unit, including income, withholding and other tax obligations, on account of
such distribution, and (ii) no distribution shall be made to or on behalf of
such holder pursuant to the Plan unless and until such holder has made
arrangements satisfactory to the Disbursing Agent for the payment and
satisfaction of such tax obligations. Any New Securities to be distributed
pursuant to the Plan shall, pending the implementation of such arrangements, be
treated as an undeliverable distribution pursuant to Article VII.G of the Plan.
It is the Debtors' intent that distributions under the Plan to holders of Claims
are in respect of, and to be applied to principal first and then interest.

         6.         Setoffs

                    The Reorganized Debtors may, but shall not be required to,
set off against any Claim (or Canadian Impaired Unsecured Claim the holder of
which has made the U.S. Plan Election if the Alternate Canadian Transactions are
implemented), and the payments or other distributions to be made pursuant to the
Plan in respect of such Claim, claims of any nature whatsoever that the Debtors
or Reorganized Debtors may have against the holder of such Claim (or Canadian
Impaired Unsecured Claim the holder of which has made the U.S. Plan Election if
the Alternate Canadian Transactions are implemented); provided, however, that
neither the failure to do so nor the allowance of any Claim (or Canadian
Impaired Unsecured Claim the holder of which has made the U.S. Plan Election if
the Alternate Canadian Transactions are implemented) hereunder shall constitute
a waiver or release by the Reorganized Debtors of any such claim that the
Debtors or Reorganized Debtors may have against such holder. Notwithstanding
anything to the contrary, the Debtors and Reorganized Debtors will not exercise
any right of setoff against any Lender, any agents under the Pre-Petition Credit
Agreement or the DIP Facility Agreement, the Account Intermediaries or the DIP
Lenders.

         7.         Shareholder Rights Plan

                    The Plan provides that a Shareholder Rights Plan will be
implemented on the Effective Date. The specific Shareholder Rights Plan to be
implemented will depend upon whether the Canadian Reorganization Plan is
sanctioned or the Alternate Canadian Transactions are implemented. If the
Canadian Reorganization Plan is sanctioned, then the Shareholder Rights Plan
will be for Reorganized PSC and governed by Canadian law. If the Alternate
Canadian Transactions are implemented, then the Shareholder Rights Plan will be
for Reorganized PSI and will be governed by United States law.

                           On the Effective Date, Reorganized PSC shall
implement the Shareholder Rights Plan. Pursuant to the Shareholder Rights Plan,
in the event that a person shall become an Acquiring Person (as defined in the
Shareholder Rights Plan) (such event being a "Flip-in Event"), each Right will
entitle the registered holder to receive, upon payment of the exercise price
stated in the Shareholder Rights Plan, that number of shares that has a market
value at the date of the Flip-in Event equal to twice the exercise price. The
Rights are not exercisable prior to the Flip-in Event. The Rights expire on the
termination of the annual meeting of shareholders of Reorganized PSC in the year
2003 unless terminated earlier by the board of directors of Reorganized PSC.

                           Until the Separation Time (as defined in the
Shareholder Rights Plan), the Rights will be evidenced only by outstanding
common share certificates. The Shareholder Rights Plan provides that, until the
Separation Time, the Rights will be transferred with and only with the
associated common shares. Until the Separation Time, or earlier termination or
expiration of the Rights, each new share certificate issued after the Record
Time (as defined in the Shareholder Rights Plan), upon transfer of existing
common shares or the issuance of additional common shares, will have printed
thereon a legend incorporating the terms of the Shareholder Rights Plan by
reference. As soon as practicable following the Separation Time, separate
certificates evidencing the Rights will be mailed to the holders of record of
common shares as of the close of business at the separation time, and thereafter
the rights certificates alone will evidence the Rights. The Rights will separate
and trade apart from the common shares after the separation time.


                                       34

<PAGE>   45


                           The board of directors of Reorganized PSC may, prior
to a Flip-in Event, waive the dilution effects of the Shareholder Rights Plan in
respect of a particular Flip-in Event that would result from a take-over bid (as
defined in the Shareholder Rights Plan) made by way of a take-over bid circular
to all holders of common shares. In such case, such waiver would be deemed also
to be a waiver, on the same terms and conditions, in respect of any other
Flip-in Event which occurs by reason of another take-over bid made by way of a
take-over bid circular to all holders of common shares and prior to the
expiration of the first take-over bid for which the initial waiver was given.
The board of directors of Reorganized PSC may also waive the Shareholder Rights
Plan in respect of a particular Flip-in Event that has occurred through
inadvertence. Additionally, the board of directors of Reorganized PSC may, at
its option, redeem all, but not less than all, of the outstanding Rights at a
nominal value at any time.

                           An Acquiring Person is, generally, a person who
becomes the Beneficial Owner of twenty percent (20%) or more of the outstanding
common shares of PSC pursuant to (a) purchases or other acquisitions, direct or
indirect, from non-residents of Canada or from persons whose securities are
registered on the books of PSC with a non-Canadian address; (b) purchases or
other acquisitions, direct or indirect, that are exempt from the Take-over Bid
circular requirements of the Securities Act (Ontario) pursuant to certain
exemptions; or (c) purchases or other acquisitions, direct or indirect, made
pursuant to a take-over bid that is not a Permitted Bid.

                           The Shareholder Rights Plan excludes from the
definition of Acquiring Person a Person who acquires twenty percent (20%) or
more of the outstanding common shares through a Permitted Bid or a Person who is
an Investment Manager, Trust Company or Plan Trustee (each as defined in the
Shareholder Rights Plan), provided they are not making or proposing to make a
Take-Over Bid.

                           A Flip-in Event does not occur if a Take-Over Bid is
a Permitted Bid. A Permitted Bid is a Take-Over Bid, made by means of a
Take-over Bid circular, which also:

                           (i)      is made to all registered holders of common
                                    shares (other than the Offeror);

                           (ii)     contains, and the provisions for the take-up
                                    and payment for common shares tendered or
                                    deposited is subject to, an irrevocable and
                                    unqualified condition that no common shares
                                    will be taken up or paid for pursuant to the
                                    Take-Over Bid prior to the close of business
                                    on a date which is not less than 45 days
                                    following the date of the Take-Over Bid; and

                           (iii)    contains an irrevocable and unqualified
                                    provision that unless the Take-Over Bid is
                                    withdrawn, all common shares may be
                                    deposited pursuant to the Take-Over Bid at
                                    any time prior to the close of business on
                                    the date of first take-up or payment for
                                    common shares under the bid and that all
                                    common shares deposited pursuant to the
                                    Take-Over Bid may be withdrawn at any time
                                    prior to the close of business on such date.

                           The Shareholder Rights Plan also provides for a
Competing Permitted Bid, which is a Take-Over Bid made during the pendency of
another Permitted Bid that satisfies all of the requirements of a Permitted Bid
except that, provided it is outstanding for a minimum period of 21 days, it may
expire on the same date as the initial Permitted Bid. A Competing Permitted Bid
must contain, and the provisions for the take-up and payment for common shares
tendered or deposited is subject to, an irrevocable and unqualified provision
that no common shares will be taken up and paid for pursuant to the Competing
Take-Over Bid prior to the close of business on the date on which common shares
may be taken up under the Permitted Bid that preceded the Competing Permitted
Bid.

                                       35
<PAGE>   46
                           In the event the Alternate Canadian Transactions are
implemented, the Shareholder Rights Plan will be revised as necessary to be
implemented by PSI and governed by United States law.

         8.         Reverse Stock Split

                           If the Canadian Reorganization Plan is sanctioned by
the Effective Date, and if Class 7 has voted to accept the Plan, on the
Effective Date, Reorganized PSC shall take all steps necessary to implement the
Reverse Stock Split. If the Alternate Canadian Transactions are implemented or
the Canadian Plan Condition is waived, no Reverse Stock Split will occur.

                    On the Effective Date, if the Canadian Reorganization Plan
has been sanctioned and Class 7 has voted to accept the Plan, Reorganized PSC
will hold a meeting of shareholders at which time, among other things,
Reorganized PSC shall request shareholder approval of the Reverse Stock Split.
The Reverse Stock Split will provide that every 273 shares of New Common Shares
become one PSC Common Share. The exchange of certificates representing New
Common Shares will be affected for PSC Common Shares pursuant to an exchange
mechanism to be implemented through Reorganized PSC's stock transfer agent. The
Reverse Stock Split is to be implemented only if the Canadian Reorganization
Plan has been sanctioned and Class 7 votes to accept the Plan. After giving
effect to the proposed Reverse Stock Split, Reorganized PSC will have
approximately 24,000,000 shares of PSC Common Shares issued and outstanding.

                    As an illustration of the effect of the Reverse Stock Split,
set forth below, is the number of New Common Shares to be distributed under the
Plan for each Class and the resulting number of PSC Common Shares for each Class
after giving effect to the Reverse Stock Split. This illustration assumes that
the Canadian Reorganization Plan is sanctioned, Class 7 votes to accept the
Plan and the class of holders of Canadian Impaired Unsecured Claims votes to
accept the Canadian Reorganization Plan.

K.       PRESERVATION OF RIGHTS OF ACTION

         Except as otherwise provided Articles IV.F and IV.I.1 of the Plan or
the Confirmation Order, or in any contract, instrument, release, indenture or
other agreement entered into in connection with the Plan, in accordance with
section 1123(b) of the Bankruptcy Code, the Reorganized Debtors shall retain and
may enforce, sue on, settle or compromise (or decline to do any of the
foregoing) all claims, rights or causes of action, suits and proceedings,

                                       36

<PAGE>   47


whether in law or in equity, whether known or unknown, that the Debtors or the
Estates may hold against any Person or entity. Each Debtor or its successor(s)
may pursue such retained claims, rights or causes of action, suits or
proceedings as appropriate, in accordance with the best interests of the
Reorganized Debtor or its successor(s) who hold such rights.

         However, if the Alternate Canadian Transactions are implemented, then
any rights, causes of action, suits and proceedings, whether in law or equity,
whether known or unknown, that PSC and/or the Canadian Debtors may
hold, including claims or causes of action, against Deloitte & Touche, Robert
Waxman, Greg Madesker and/or Rik Barrese shall remain the property of PSC and
the Canadian Debtors and shall remain subject to the Lenders' Claims to the
extent such Claims have not been satisfied in full as a result of distributions
pursuant to the Plan. The Reorganized Debtors will not own, control, prosecute
or receive any proceeds from the successful prosecution or settlement of these
causes of action. These causes of action will be prosecuted by PSC and the
Canadian Debtors. Under the Alternate Canadian Transactions, the Lenders will
retain their security interests and deficiency claims against all remaining
assets of PSC and the Canadian Debtors after giving effect to the Alternate
Canadian Transactions. The prosecution of the causes of action against Deloitte
& Touche and Robert Waxman shall be governed by the terms of the Alternate
Canadian Transactions and applicable Canadian law and any recoveries shall be
for the benefit of the Lenders on account of their Claims against the Canadian
Debtors. In the event such proceeds satisfy the Lenders' deficiency claims in
full, then any excess proceeds would be distributed to creditors of PSC in
accordance with applicable Canadian law. The proceeds will not be distributed to
the Reorganized Debtors and the Reorganized Debtors will have no economic stake
in the prosecution of the causes of action against Deloitte & Touche and Robert
Waxman.

         Claims against Deloitte & Touche have been asserted in the U.S. and
Canadian Class Actions alleging that Deloitte & Touche was negligent in
performing its duties as auditors for PSC by failing to discover and disclose
certain information in the Debtors' financial statements. The Debtors may have
similar claims or causes of action against Deloitte & Touche for breach of its
duties to the Debtors in connection with Deloitte & Touche audits. The Debtors
have not finalized an analysis of such claims and are not prepared to undertake
any estimate of the value of any such claims or the likelihood of recovery.

         If the Canadian Reorganization Plan is implemented, then the causes of
action against Deloitte & Touche and Robert Waxman will constitute causes of
action retained by the Reorganized Debtors and will be prosecuted or settled by
the Reorganized Debtors. Any proceeds obtained from the prosecution or
settlement of these causes of action would inure to the benefit of the
stockholders of the Reorganized Debtors.

         The failure of the Debtors to specifically list any claim, right of
action, suit, or proceeding herein or in the Plan does not, and will not be
deemed to, constitute a waiver or release by the Debtors of such claim, right of
action, suit, or proceeding, and the Reorganized Debtors will retain the right
to pursue additional claims, rights of action, suits or proceedings. In
addition, at any time before the Effective Date, notwithstanding anything in the
Plan to the contrary, the Debtors or the Reorganized Debtors may settle some or
all of the Litigation Claims with the approval of the Bankruptcy Court pursuant
to Fed. R. Bankr. P. 9019.

whole or in part on any act, omission, transaction, event or other occurrence

M.       CONDITIONS TO CONFIRMATION AND/OR CONSUMMATION

         Described below are certain important considerations under the
Bankruptcy Code in connection with confirmation of the Plan.

         1.         Requirements for Confirmation of the Plan

                    The Bankruptcy Court will determine at a hearing on
confirmation of the Plan (the "Confirma tion Hearing") whether the following
requirements for confirmation, set forth in section 1129 of the Bankruptcy Code,
have been satisfied:

                    (a)    The Plan complies with the applicable provisions of
                           the Bankruptcy Code.

                    (b)    The Debtors have complied with the applicable
                           provisions of the Bankruptcy Code.

                    (c)    The Plan has been proposed in good faith and not by
                           any means forbidden by law.

                    (d)    Any payment made or promised by the Debtors or by a
                           person issuing securities or acquiring property under
                           the Plan for services or for costs and expenses in,
                           or in connec tion with, the Chapter 11 Cases, or in
                           connection with the Plan and incident to the Chapter
                           11 Cases, has been disclosed to the Bankruptcy Court,
                           and any such payment made before confirmation of the
                           Plan is reasonable, or if such payment is to be fixed
                           after confirmation of the Plan, such payment is
                           subject to the approval of the Bankruptcy Court as
                           reasonable.


                                       40

<PAGE>   51

                    (e)    The Debtors have disclosed (i) the identity and
                           affiliations of (x) any individual proposed to serve,
                           after confirmation of the Plan, as a director,
                           officer, or voting trustee of the Reorganized
                           Debtors, (y) any affiliate of the Debtors
                           participating in a joint plan with the Debtors, or
                           (z) any successor to the Debtors under the Plan (and
                           the appointment to, or continuance in, such office of
                           such individual(s) is consistent with the interests
                           of Creditors and Interest holders and with public
                           policy), and (ii) the identity of any insider that
                           will be employed or retained by the Debtors and
                           the nature of any compensation for such insider.

                    (f)    With respect to each Class of Claims or Interests,
                           each Impaired Creditor and Impaired Interest holder
                           either has accepted the Plan or will receive or
                           retain under the Plan on account of the Claims or
                           Interests held by such entity, property of a value,
                           as of the Effective Date, that is not less than the
                           amount that such entity would receive or retain if
                           the Debtors were liquidated on such date under
                           Chapter 7 of the Bankruptcy Code. (See Article XI.C
                           of the Disclosure Statement, entitled "Feasibility of
                           the Plan and the Best Interest of Creditors -- Best
                           Interests Test.")

                    (g)    The Plan provides that Administrative Claims and
                           Priority Claims other than Priority Tax Claims will
                           be paid in full on the Effective Date and that
                           Priority Tax Claims will receive on account of such
                           Claims deferred cash payments, over a period not
                           exceeding six years after the date of assessment of
                           such Claims, of a value, as of the Effective Date,
                           equal to the Allowed Amount of such Claims, except to
                           the extent that the holder of any such Claim has
                           agreed to a different treatment.

                    (h)    If a Class of Claims is Impaired under the Plan, at
                           least one Class of Impaired Claims has accepted the
                           Plan, determined without including any acceptance of
                           the Plan by insiders holding Claims in such Class.

                    (i)    Confirmation of the Plan is not likely to be followed
                           by the liquidation, or the need for further financial
                           reorganization, of the Debtors or any successor to
                           the Debtors under the Plan, unless such liquidation
                           or reorganization is proposed in the Plan. (See
                           Article XI.A of the Disclosure Statement, entitled
                           "Feasibility of the Plan and the Best Interest of
                           Creditors -- Feasibility of the Plan.")

                    (j)    The Plan provides for the continuation after the
                           Effective Date of all retiree benefits, if any, at
                           the level established pursuant to section
                           1114(e)(1)(B) or 1114(g) of the Bankruptcy Code at
                           any time prior to confirmation of the Plan, for the
                           duration of the period the Debtors have obligated
                           themselves to provide such benefits.

                    The Debtors believe that, upon receipt of the votes required
to confirm the Plan, the Plan will satisfy all the statutory requirements of
Chapter 11 of the Bankruptcy Code, that the Debtors have complied or will have
complied with all of the requirements of Chapter 11, and that the Plan has been
proposed and submitted to the Bankruptcy Court in good faith.

         2.         Conditions to Confirmation and Consummation

                    (a)    Conditions to Confirmation

                           The following are conditions precedent to the
occurrence of the Confirmation Date: (i) an order finding that the Disclosure
Statement contains adequate information pursuant to section 1125 of the


                                       41

<PAGE>   52


Bankruptcy Code, and (ii) the proposed Confirmation Order shall be in form and
substance acceptable to the Debtors and the Required Lenders.

                    (b)    Conditions to Consummation

                           The following are conditions precedent to the
occurrence of the Effective Date, each of which may be satisfied or waived in
accordance with Article X.C of the Plan:

                           (i)      The Confirmation Order confirming the Plan,
                                    as such Plan may have been modified, shall
                                    have been entered and become a Final Order
                                    in form and substance reasonably
                                    satisfactory to the Debtors and the Required
                                    Lenders and shall provide that:

                                    (1)     the Debtors and Reorganized Debtors
                                            are authorized and directed to take

                                    Reorganization Plan and all conditions to
                                    the effectiveness of the Canadian
                                    Reorganization Plan shall have been
                                    satisfied other than the condition that the
                                    Plan shall have become effective or (b) the
                                    Alternate Canadian Transactions shall have
                                    been authorized to be implemented in
                                    accordance with Canadian law and all
                                    conditions to the implementation of the
                                    Alternate Canadian Transactions shall have

                                    condition to the transactions shall be the
                                    effectiveness of the Plan.

                                    PSC (if the Canadian Reorganization Plan is
                                    sanctioned) or Reorganized PSI (if the
                                    Alternate Canadian Transactions are
                                    implemented or if the Canadian Plan
                                    Condition is waived) shall have been
                                    appointed.

                    (c)    Waiver of Conditions

                           Each of the conditions set forth in Article X.B of
the Plan may be waived in whole or in part by the Debtors with the written
consent of the Required Lenders, without any other notice to parties in interest
or the Bankruptcy Court and without a hearing. The failure to satisfy or waive
any condition to the Effective Date

                                       43

<PAGE>   54

may be asserted by the Debtors or Debtors regardless of the circumstances
giving rise to the failure such condition to be satisfied (including any
action or inaction by a Debtor or Debtor). The failure of a Debtor or
Reorganized Debtor to exercise of the foregoing rights shall not be deemed a
waiver of any other rights, each such right shall be deemed an ongoing right
that may be asserted at any .

                           If the Canadian Plan Condition is waived, (a) all New
Securities shall be issued by Reorganized PSI, (b) PSC and the other Canadian
Debtors will continue to be managed by PSC's current board of directors and
current management and (c) until either the Canadian Reorganization Plan is
sanctioned or the Alternate Canadian Transactions are implemented, all assets of
PSC and the other Canadian Debtors will continue to be owned and operated by PSC
and the other Canadian Debtors, respectively. If the Canadian Plan Condition is
waived, it is contemplated that substantially all equity interests and/or assets
of PSC and the other Canadian Debtors ultimately will be transferred as going
concerns to Reorganized PSI and/or a newly formed or existing direct or indirect
subsidiary or subsidiaries of Reorganized PSI.

         3.         Modifications and Amendments

                    Subject to Article XI of the Plan and the consent of the
Required Lenders, after giving notice to the Creditors' Committee and the
Indenture Trustee, and to the extent of any modification to the treatment of the
Account Intermediaries as holders of Other Secured Claims, the consent of the
Account Intermediaries, the Debtors may alter, amend, or modify the Plan or any
Exhibits thereto under section 1127(a) of the Bankruptcy Code at any time prior
to the Confirmation Date. After the Confirmation Date and prior to "substantial
consummation" of the Plan, as defined in section 1101(2) of the Bankruptcy Code,
the Debtors may, under section 1127(b) of the Bankruptcy Code, institute
proceedings in the Bankruptcy Court to remedy any defect or omission or
reconcile any inconsistencies in the Plan, the Disclosure Statement approved
with respect to the Plan, or the Confirmation Order, and such matters as may be
necessary to carry out the purpose and effect of the Plan so long as they have
obtained prior approval of the Required Lenders and such proceedings do not
adversely affect the treatment of holders of Claims or Interests under the Plan
(it being specifically understood that any settlement of a claim of the Estates
against any party specifically excluded from the releases provided in Article
IV.I of the Plan shall be deemed to have a material adverse affect on the
treatment of holders of Claims and Interests); provided, however, that prior
notice of such proceedings shall be served in accordance with the Bankruptcy
Rules or order of the Bankruptcy Court.

N.       WAIVER OF CONDITIONS TO CONFIRMATION AND/OR CONSUMMATION

         Each of the conditions set forth in Article X of the Plan may be waived
in whole or in part by the Debtors with the written consent of the Required
Lenders without any other notice to parties in interest or the Bankruptcy Court
and without a hearing. The failure to satisfy or waive any condition to the
Effective Date may be asserted by the Debtors or Reorganized Debtors regardless
of the circumstances giving rise to the failure of such condition to be
satisfied (including any action or inaction by a Debtor or Reorganized Debtor).
The failure of a Debtor or the Reorganized Debtor to exercise any of the
foregoing rights shall not be deemed a waiver of any other rights, and each such
right shall be deemed an ongoing right that may be asserted at any time.

O.       EFFECT OF WAIVER OF CANADIAN PLAN CONDITION RELATING TO SANCTIONING OF
         CANADIAN REORGANIZATION PLAN

         It is anticipated that the Canadian Reorganization Plan can be
sanctioned or the Alternate Canadian Transactions are implemented concurrently
with the Effective Date of the Plan. If, however, it is determined that this
condition to the Plan will unreasonably delay the Effective Date, the Debtors,
with the consent of the Required Lenders may waive this condition. In the event
the Canadian Plan Condition is waived, no distributions will be made to holders
of Claims in Classes 8B or 8C or holders of Canadian Impaired Unsecured Claims
that have made the U.S. Plan Election pending the conclusion of the Canadian
Cases. In that event the distributions that would have been made to such
creditors, as well as any Class 6 Additional will be held by

                                       44

<PAGE>   55

Reorganized PSI the Canadian Debtors until such as either a Canadian
Reorganization Plan is or the Alternate Transactions are implemented and then
subsequently distributed as under the Plan.

P.       EFFECTS OF CONFIRMATION

         1.         Binding Effect

                    The Plan will be binding upon and inure to the benefit of
the Debtors, all present and former holders of Claims against and Interests in
the Debtors, whether or not such holders will receive or retain any property or
interest in property under the Plan, their respective successors and assigns,
including, but not limited to, the Reorganized Debtors, and all
parties-in-interest in the Chapter 11 Cases.

         2.         Discharge of the Debtors

                    Except as otherwise provided in the Plan or in the
Confirmation Order, all consideration distributed under the Plan will be in
exchange for, and in complete satisfaction, settlement, discharge, and release
of, all Claims (other than those Reinstated under the Plan) of any nature
whatsoever against the Debtors or any of their assets or properties, and
regardless of whether any property will have been distributed or retained
pursuant to the Plan on account of such Claims, and upon the Effective Date, the
Debtors shall (i) be deemed discharged and released under section 1141(d)(1)(A)
of the Bankruptcy Code from any and all Claims, including, but not limited to,
demands and liabilities that arose before the Confirmation Date, and all debts
of the kind specified in sections 502(g), 502(h) or 502(i) of the Bankruptcy
Code, whether or not (a) a Proof of Claim based upon such debt is filed or
deemed filed under section 501 of the Bankruptcy Code, (b) a Claim based upon
such debt is Allowed under section 502 of the Bankruptcy Code, or (c) the holder
of a Claim based upon such debt accepted the Plan and (ii) terminate all
Interests of the holders of (A) Other Equity Securities, and (B) if Class 7
votes to reject the Plan, Old Common Shares.

                    As of the Confirmation Date, except as provided in the Plan
or the Confirmation Order, all entities shall be precluded from asserting
against the Debtors or the Reorganized Debtors, their successors or their
property any other or further claims, debts, rights, causes of action,
liabilities or equity interests relating to the Debtors based upon any act,
omission, transaction or other activity of any nature that occurred prior to the
Confirmation Date; provided however, that nothing in the Plan shall be deemed to
preclude any third party (other than the releasing parties in Article IV.I.2.(a)
of the Plan to the extent provided therein) from asserting claims, debts,
rights, causes of action, liabilities or equity interests that are not property
of the Estates under section 541 of the Bankruptcy Code against any current or
former officers, directors or employees of the Debtors or Reorganized Debtors;
provided further, that notwithstanding anything contained in the Plan to the
contrary, rights and claims of the United States under environmental laws or
regulations shall not be discharged, impaired or otherwise affected by the Plan
and the Chapter 11 Cases, shall survive the Chapter 11 Cases as if the Chapter
11 Cases had not been commenced and shall be determined in the manner and by the
administrative or judicial tribunals in which such rights or claims would have
been resolved or adjudicated if the bankruptcy cases had not been commenced. In
accordance with the foregoing, except as provided in the Plan or the
Confirmation Order, the Confirmation Order shall be a judicial determination of
discharge of all such Claims and other debts and liabilities against the Debtors
and termination of all Interests of the holders of (i) Other Equity Securities
and (ii) if Class 7 votes to reject the Plan, Old Common Shares, pursuant to
sections 524 and 1141 of the Bankruptcy Code, and such discharge shall void any
judgment obtained against the Debtors at any time, to the extent that such
judgment relates to a discharged Claim or terminated Interest.

         3.         Permanent Injunction

                    Except as provided in the Plan or the Confirmation Order, as
of the Confirmation Date, all entities that have held, currently hold or may
hold a Claim or other debt or liability that is discharged or an Interest or
other right of an equity security holder that is Impaired or terminated pursuant
to the terms of the Plan are permanently enjoined from the taking of any of the
following actions against the Debtors, the Reorganized Debtors or their property
on account of any such discharged Claims, debts or liabilities or terminated

place, any action or other proceeding: (b) enforcing, attaching, collecting or
recovering in any manner any judgment, award, decree or order; (c) creating,
perfecting or enforcing any lien or encumbrance; (d) asserting a setoff, right
of subrogation or recoupment of any kind against any debt, liability or
obligation due to the Debtors and (e) commencing or continuing any action, in
any manner, in any place that does not comply with or is inconsistent with the
provisions of the Plan.

currently hold or may hold a claim, demand, debt, right, cause of action or
liability that is released pursuant to Article IV.I or XIV.H of the Plan are

released claims, obligations, suits, judgments, damages, demands, debts, rights,
causes of action or liabilities: (a) commencing or continuing in any manner any
action or other proceeding; (b) enforcing, attaching, collecting or recovering
in any manner any judgment, award, decree or order; (c) creating, perfecting or
enforcing any lien or encumbrance: (d) asserting a setoff, right of subrogation
or recoupment of any kind against any debt, liability or obligation due to any
released entity; and (e) commencing or continuing any action, in any manner, in
any place that does not comply with or is inconsistent with the provisions of
the Plan.

                    By accepting distribution pursuant to the Plan, each holder
of an Allowed Claim or Allowed Interest receiving distributions pursuant to the
Plan will be deemed to have specifically consented to the injunctions in the
Plan.

         4.         Exculpation and Limitation on Liability; Indemnity

                    Neither the Debtors, the Subsidiaries, the Reorganized
Debtors, the Lenders, any individual, corporation or other entity that was at
any time formerly a Lender, the ad hoc steering committee or any other committee
of holders of Lender Claims, CIBC as Administrative Agent and co-arranger under
the Pre-Petition Credit Agreement, BTCo as Syndication Agent and co-arranger
under the Pre-Petition Credit Agreement, any official committees appointed in
the Chapter 11 Cases, the DIP Agent, the DIP Co-Arrangers and the holders of DIP
Facility Claims, the Security Agent, and the Account Intermediaries, or any of

of a Claim or an Interest, or any other party in interest, or any of their
respective agents, employees, representatives, financial advisors, attorneys, or
affiliates, or any of their successors or assigns, for any act or omission in
connection with, relating to, or arising out of, the Chapter 11 Cases,
formulating, negotiating or implementing the Plan, the Lender Lock-up Agreement
or the Allwaste Lock-up Agreement, the solicitation of acceptances of the Plan
or the Lender Lock-up Agreement, the pursuit of confirmation of the Plan, the
confirmation of the Plan, the consummation of the Plan, or the administration of
the Plan or the property to be distributed under the Plan, except for their
willful misconduct, and in all respects shall be entitled to rely reasonably
upon the advice of counsel with respect to their duties and responsibilities
under the Plan.

                    Notwithstanding any other provision of the Plan, no
holder of a Claim or Interest, no other party in interest, none of their
respective agents, employees, representatives, financial advisors, attorneys, or
affiliates, and no successors or assigns of the foregoing, shall have any right
of action against any Debtor, Subsidiary or Reorganized Debtor, any Lender or
any individual, corporation or other entity that was at any time formerly a
Lender, the ad hoc steering committee or any other committee of holders of
Lender Claims, CIBC as Administrative Agent and co-arranger under the
Pre-Petition Credit Agreement, BTCo as Syndication Agent and co-arranger under

                                       46

<PAGE>   57

the Pre-Petition Credit Agreement, any official committees appointed in the
Chapter 11 Cases, the DIP Agent, the DIP Co-Arrangers and the holders of DIP
Facility Claims, the Security Agent, and the Account Intermediaries, or any of
their respective present or former members, officers, directors, employees,
advisors, attorneys, affiliates, or agents, for any act or omission in
connection with, relating to, or arising out of, the Chapter 11 Cases,
formulating, negotiating or implementing the Plan, the Lender Lock-up Agreement
or the Allwaste Lock-up Agreement, the solicitation of acceptances of the Plan
or the Lender Lock-up Agreement, the pursuit of confirmation of the Plan, the
consummation of the Plan, the confirmation of the Plan, or the administration of
the Plan or the property to be distributed under the Plan, except for their
willful misconduct.

                    The Debtors, the Reorganized Debtors and the Subsidiaries
hereby jointly and severally fully indemnify each of the Lenders, any individual
corporation or other entity that was at any time formerly a Lender, a member of
the ad hoc steering committee or any other committee of holders of Lender
Claims, CIBC as Administrative Agent and co-arranger under the Pre-Petition
Credit Agreement, BTCo as Syndication Agent and co-arranger under the
Pre-Petition Credit Agreement, the DIP Agent, the DIP Co-Arrangers and the
holders of DIP Facility Claims, the Security Agent, and the Account
Intermediaries, and their respective agents, affiliates, directors, officers,
employees, and representatives, including counsel (collectively, the
"Indemnitees") against any manner of actions, causes of action, suits,
proceedings, liabilities and claims of any nature, costs and expenses (including
reasonable legal fees) which may be incurred by such Indemnitee or asserted
against such Indemnitee arising out of or during the course of, or otherwise in
connection with or in any way related to, the negotiation, preparation,
formulation, solicitation, dissemination, implementation, confirmation and
consummation of the Plan, other than any liabilities to the extent arising from
the gross negligence or willful or intentional misconduct of any Indemnitee as
determined by a final judgment of a court of competent jurisdiction. If any
claim, action or proceeding is brought or asserted against an Indemnitee in
respect of which indemnity may be sought from any of the Reorganized Debtors or
any of the Subsidiaries, the Indemnitee shall promptly notify the Reorganized
Debtors in writing, and the Reorganized Debtors may assume the defense thereof,
including the employment of counsel reasonably satisfactory to the Indemnitee,
and the payment of all costs and expenses. The Indemnitee shall have the right
to employ separate counsel in any such claim, action or proceeding and to
consult with the Reorganized Debtors in the defense thereof and the fees and
expenses of such counsel shall be at the expense of the Reorganized Debtors
unless and until the Reorganized Debtors shall have assumed the defense of such
claim, action or proceeding. If the named parties to any such claim, action or
proceeding (including any impleaded parties) include both the Indemnitee and any
of the Reorganized Debtors or Subsidiaries, and the Indemnitee reasonably
believes that the joint representation of such entity and the Indemnitee may
result in a conflict of interest, the Indemnitee may notify the Reorganized
Debtors in writing that it elects to employ separate counsel at the expense of
the Reorganized Debtors, and the Reorganized Debtors shall not have the right to
assume the defense of such action or proceeding on behalf of the Indemnitee. In
addition, the Reorganized Debtors shall not effect any settlement or release
from liability in connection with any matter for which the Indemnitee would have
the right to indemnification from the Reorganized Debtors, unless such
settlement contains a full and unconditional release of the Indemnitee, or a
release of the Indemnitee satisfactory in form and substance to the Indemnitee.

Q.       RETENTION OF JURISDICTION

         Pursuant to sections 105(a) and 1142 of the Bankruptcy Code, and
notwithstanding entry of the Confirmation Order and occurrence of the Effective
Date, subject to the Protocol, the Bankruptcy Court will, to the fullest extent
permitted by law, retain exclusive jurisdiction over all matters arising out of,
and related to, the Chapter 11 Cases and the Chapter 11 Plan, and the Ontario
Superior Court of Justice administrating the parallel CCAA proceedings will
retain exclusive jurisdiction over all matters arising out of, and related to,
the CCAA cases and the CCAA plan, as more fully set forth in Article XII of the
Plan.

                                  ARTICLE III.

              TREATMENT OF TRADE CREDITORS, CUSTOMERS AND EMPLOYEES

A.       TRADE CREDITORS

         Notwithstanding provisions of the Bankruptcy Code that would otherwise
require payment of such prepetition claims to be deferred until consummation of
the Plan, the Debtors have obtained the approval of the Bankruptcy Court to make
payments on certain prepetition claims of key trade vendors who agree to provide
goods and services on the same terms as those that were in effect prior to the
Petition Date (the "Key Trade Vendor Order"). On July 19, 1999, the Key Trade
Vendor Order was appealed by Republic. Republic's appeal is based on the issue
of the Bankruptcy Court's discretion to enter the Key Trade Vendor Order.
Republic alleges the general unsecured creditors did not receive adequate notice
of the hearing at which the Key Trade Vendor Order was entered and an inadequate
evidentiary record existed upon which to enter the Key Trade Vendor Order. This
appeal is still pending.

B.       CUSTOMERS/CLIENTS

         It is the intent of the Debtors that the Chapter 11 Cases offer no
disruption of service to the Debtors' customers and clients. The Bankruptcy
Court has authorized the Debtors to honor certain prepetition customer practices
and obligations to customers the Debtors deem necessary, in the same manner such
practices were implemented and such obligations were honored before the
commencement of the Chapter 11 Cases, including but not limited to customer
discounts, credits or deposits, and certain other contractual obligations.

C.       EMPLOYEES

         The Debtors intend that salaries, wages, accrued vacation pay,
health-related benefits, and similar employee benefits for current employees
will be unaffected. Employee benefit claims that accrue pre-petition, with the
exception of certain severance obligations identified as Impaired Unsecured
Claims, will be Unimpaired under the terms of the Plan. To ensure the continuity
of the Debtors' work force and to further accommodate the Unimpaired treatment
of employee benefits, the Debtors have obtained the approval of the Bankruptcy
Court to honor payroll checks outstanding as of the Petition Date (or to issue
replacement checks), to permit employees to use their accrued vacation time (as
long as they remain employees of the Debtors) and to continue paying medical
benefits under the Debtors' health plan.


                                   ARTICLE IV.

     HISTORY OF THE DEBTORS AND EVENTS LEADING TO CHAPTER 11 FILING AND PLAN

A.       OVERVIEW OF BUSINESS OPERATIONS

         1.         Business Segments

                    PSC's business is organized into two operating divisions,
the Metals Services Group and the Industrial Services Group. The Metal Services
Group's primary business operations are ferrous processing and industrial metals
services. The ferrous metals operations include the collection and processing of
ferrous scrap materials for shipment to steel mills and the provision of
significant brokerage services for scrap materials. The industrial metals
services include on-site services, by-product management and coil processing and
distribution services to steel mills. The Metals Services Group primarily
services the steel, foundry and automotive industries.


                                       48

<PAGE>   59



                    The Debtors believe that their Industrial Services Group is
one of the largest integrated providers of by-products recovery and industrial
outsourcing services in North America, with a network of over 200 facilities.
By-products recovery includes solvent distillation, engineered fuel blending,
paint overspray recovery, organic and inorganic waste collection processing and
polyurethane recycling. Industrial outsourcing services include cleaning and
maintenance, waste collection and transportation, container services and tank
cleaning, turnaround and outage services, mechanical contracting, refractory
services, decommissioning and remediation, analytical services and emergency
response services. The Industrial Services Group primarily services the
automotive, refining and petrochemical, oil and gas, pulp and paper, steel,
transportation and utilities industries.

         2.         Accompanying Financial Data

                    The financial data contained in PSC's Annual Report on Form
10-K for the fiscal year ended December 31, 1998 and Quarterly Report on Form
10-Q for the fiscal quarter ended June 30, 1999 are attached in Appendix D-1 and
D-2 to the Disclosure Statement, respectively, and are herein incorporated by
reference.

         3.         Certain Legal Proceedings

                    Certain of the Debtors' facilities are contaminated
primarily as a result of practices at the sites prior to their acquisition by
the Debtors. The Debtors have established procedures to routinely evaluate these
sites giving consideration to the nature and extent of the contamination. The
Debtors have reserved for the remediation of these sites based upon management's
judgment and prior experience. The Debtors have estimated the liability to
remediate these sites to be approximately $68.0 million.

                    In addition, certain of PSC's subsidiaries have been named
as potentially responsible or liable parties in connection with sites listed on
the Superfund National Priority List ("NPL"). In the majority of situations,
PSC's connection with NPL sites relates to allegations that the Debtors or their
predecessors transported waste to the site in question. PSC has reviewed the
nature and extent of its alleged connection to these sites, the number,
connection and financial ability of the other named and unnamed potentially
responsible parties and the nature and estimated cost of the likely remedy.
Based on its review, PSC has estimated its liability in connection with these
sites to be approximately $20.8 million.

                    Various class actions have been filed against PSC, certain
of its past and present directors and officers, the underwriters of PSC's 1997
public offering and PSC's auditors. Each action alleges that PSC's financial
disclosures for various time periods between 1995 and 1997 contained material
misstatements or omissions in violation of U.S. federal securities laws
(provisions of the Securities Act of 1933 and of the Securities Exchange Act of
1934) and seeks to represent a class of purchasers of PSC's common shares. On
June 2, 1998, the Judicial Panel on Multidistrict Litigation ordered that the
class actions be consolidated and transferred to the United States District
Court, Southern District of New York. On July 23, 1998, two pre-trial orders of
the District Court were made. Pre-Trial Order No. 1 dealt with various
administrative matters relating to the consolidation of the actions and a
schedule for the plaintiffs to serve and file a consolidated amended class
action complaint and for PSC's response. Pre-Trial Order No. 2 appointed a lead
plaintiff and lead counsel. On November 13, 1998, PSC filed a motion for an
order dismissing the class action on the grounds of forum non conveniens. On May
4, 1999, PSC's motion was granted and the class action was dismissed.

                    A claim (the "Canadian Class Action") brought under the
Ontario Class Proceedings Act was commenced on May 5, 1998 against PSC, the
underwriters of PSC's 1997 public offering and PSC's auditors. The claim was
brought on behalf of persons in Canada who purchased PSC common shares between
November 6, 1997 and December 18, 1997, and also seeks damages on behalf of
persons in Canada who purchased common shares between May 21, 1996 and April 23,
1998. The plaintiff class in the Canadian Class Action has been certified. The
Canadian Class Action contains various allegations that are similar in nature to
those made in the U.S. class action claims dismissed on May 4, 1999.


                                       49

<PAGE>   60


                    The claims and causes of action against the Debtors held by
United States residents described in the preceding two paragraphs are classified
in the Plan as Class 8B Claims. On June 23, 1999, the Debtors entered into a
Memorandum of Understanding (the "MOU") to settle these claims, as well as such
claims and causes of action held by United States residents. This settlement is
embodied in the Plan providing an aggregate distribution (if Class 7 votes to
accept the Plan) of one and one-half percent (1.5%) of PSC Common Shares to
holders of Allowed Class 8B Claims and Canadian Class action members if the
Canadian Class Action settlement is approved. Additionally, the MOU reflects the
Debtors' commitment to support a joint application for attorneys' fees and
reasonable expenses of plaintiff's counsel not to exceed $575,000, subject to
approval by the Bankruptcy Court, and which shall not be payable until after the
Effective Date.

                    Under the Plan, the Class 8B Claims will be discharged as of
the Effective Date. Therefore, if the Plan is confirmed and consummated, after
the Effective Date, the Securities Claims in the Securities Actions cannot be
pursued against the Reorganized Debtors.

                    Similar claims have been asserted against PSC and certain of
its past and present officers and directors by the former shareholders of the
Steiner-Liff Metals group of companies and the Southern-Foundry Supply group of
companies. PSC acquired these companies in October 1997 and issued PSC common
shares in partial payment of the purchase price. The claims allege that PSC's
financial disclosures for various time periods between 1995 and 1997 contain
material misstatements or omissions and that these constitute a breach of
certain representations and warranties made to the former shareholders or,
alternatively, a violation of United States securities laws. Under the Plan,
these claims and causes of action are classified in Class 8C as the Liff Actions
and the Chazen Actions. The Plan provides that the Claims against the Debtors
arising from the Liff Actions and the Chazen Actions will be discharged on the
Effective Date. Therefore, if the Plan is confirmed and consummated, after the
Effective Date, the Claims arising from the Liff Actions and the Chazen Actions
cannot be pursued against the Reorganized Debtors.

                    Upon the acquisition of Allwaste, Inc. ("Allwaste"), PSC
assumed the pre-existing Indenture with respect to Allwaste's 7 1/4 %
Convertible Subordinated Debentures ("Old Debentures") which are due in 2014.
Effective December 1, 1998, PSC suspended payments of interest on the Old
Debentures which created a default under the Indenture. Following PSC's failure
to cure the payment default within thirty days, on April 22, 1999, First Union
National Bank (the "Indenture Trustee") invoked an acceleration clause and
declared the principal of all the Old Debentures to be immediately due and
payable. On April 27, 1999, the Indenture Trustee filed suit in the 11th
Judicial District Court of Harris County, Texas seeking the full amount due and
owing under the Old Debentures (the "Allwaste Collection Action").

                    The commencement of the Chapter 11 Cases automatically
stayed the further prosecution of the Allwaste Collection Action pursuant to
section 362(a) of the Bankruptcy Code. Moreover, the Debtors believe that the
Bankruptcy Court has exclusive jurisdiction over the causes of action asserted
in the Allwaste Collection Action and that such matters will be adjudicated in
the Chapter 11 Cases by the Bankruptcy Court. Under the Plan, claims arising out
of the Old Debentures are classified as Class 7 Impaired Unsecured Claims and
will receive the treatment afforded such claims and will be discharged under the
Plan as of the Effective Date. Therefore, if the Plan is confirmed and
consummated, after the Effective Date, the Reorganized Debtors will have no
liability as to the Old Debentures and the Allwaste Collection Action will be
fully resolved and will be dismissed with prejudice.

                    On May 25, 1999, the Indenture Trustee filed suit
against PSC and the Lenders in the 11th Judicial District Court of Harris
County, Texas (the "Allwaste Avoidance Action") alleging that any and all liens,
security interests, and obligations conveyed or transferred by PSC to its
Lenders were avoidable as fraudulent conveyances. The Debtors believe that the
commencement of the Chapter 11 Cases has vested exclusive standing to prosecute
avoidance actions, including those asserted by the Indenture Trustee against the
defendant Lenders in the Allwaste Avoidance Action, in the Debtors pursuant to
the Bankruptcy Code. Therefore, the Debtors believe that the causes of action
alleged in the Allwaste Avoidance Action are property of the Debtors' Estates
and that further

                                       50

<PAGE>   61
prosecution of the Allwaste Avoidance Action is stayed pursuant to section
362(a) of the Bankruptcy Code. Under the terms of the Plan, the causes of action
asserted by the Indenture Trustee against the defendant Lenders will be deemed
to be settled and released as a consequence of the treatment of all Claims and
Interests, including the Claims of the Lenders and the holders of Old Debentures
under the Plan. Therefore, if the Plan is confirmed and consummated, as of the
Effective Date, the Allwaste Avoidance Action will be fully resolved and will be
dismissed with prejudice.

                    During the pendency of the cases, certain creditors have
asserted that the Debtors could pursue a cause of action against PSC and the
Lenders alleging that any and all liens, security interests, and guarantees
conveyed or transferred by PSC to its Lenders were avoidable as fraudulent
conveyances under applicable state law. The Debtors have reviewed the potential
for such claims and concluded that such claims are without any meaningful value.
Pursuit of such claims would involve lengthy and costly litigation concerning a
number of issues which the Lenders would vehemently contest, and would
undoubtedly delay the Debtors' emergence form Chapter 11 to the detriment of all
parties. The Creditors' Committee has conducted its own evaluation of these
issues and the likely results and has reached the same conclusion. Any such
claims will be released and discharged under the Plan.

                    On July 30, 1999, Great Plains Trust Company and Kornitzer
Capital Management, Inc. ("Plaintiffs") filed a class action petition against
Robert M. Christe, R.L. Nelson, Jr., T. Wayne Wren, Jr., Michael W. Ramirez,
David E. Fanta, James E. Rief, William L. Fiedler, Michael A. Baker, John U.
Clarke, Frank A. Rossi, Thomas J. Tierney and T. Michael Young (the "Allwaste
Officers and Directors"), in the District Court of Harris County, Texas. These
individuals are all directors and officers of the former Allwaste Inc. The
Plaintiffs manage funds which hold Old Debentures issued under the Debtors' July
30, 1997 Supplemental Indenture entered into at the same time PSC acquired
Allwaste. Plaintiffs allege that the Allwaste Officers and Directors did not
fully investigate the fairness and advisability of the PSC offer to purchase
Allwaste, which acquisition purportedly caused the value of the Plaintiffs' Old
Debentures to substantially decrease from their value prior to or immediately
after PSC's acquisition of Allwaste.

                    In June 1997, pursuant to a Share Purchase Agreement,
Republic sold certain corporate entities to RESI Acquisition (Delaware), Inc.
("RESI"), for $17 million. As consideration for the transaction, RESI paid $8
million in cash and executed two promissory notes in favor of Republic in a
combined amount of $9 million. PSC, the parent of RESI, signed the notes as
unconditional guarantor and also signed a separate Guaranty Agreement. After the
notes were executed, the parties made several modifications to the payment
schedule, allowing RESI extra time to fulfill its obligations. However, RESI
eventually defaulted and Republic thereafter brought an action in the Superior
Court of the State of Delaware against PSC and RESI to collect on the notes (the
"Republic Action"). In addition to the note involved in the Republic Action,
another note issued by Philip Enterprises Inc. in conjunction with the RESI
acquisition exists and is the subject of litigation in Canada that has now been
stayed in connection with the filing of the Canadian Cases. PSC filed
counterclaims alleging damages from the 1997 Share Purchase Agreement. On June
3, 1999, the court issued judgment granting Republic's Motion for Final Judgment
on the Pleadings as to the Notes and Guaranty, and denying PSC's Motion to
Dismiss. On June 4, 1999, RESI filed a petition for relief under Chapter 11 of
the Bankruptcy Code in the United States Bankruptcy Court for the District of
Delaware. As a result of its Chapter 11 filing, the Republic Action against RESI
is now stayed pursuant to section 362(a) of the Bankruptcy Code. The Claims of
Republic are classified under the Plan as Class 7 Impaired Unsecured Claims,
will receive the treatment afforded such claims, and will be discharged under
the Plan as of the Effective Date. Therefore, if the Plan is confirmed and
consummated, as of the Effective Date, the Reorganized Debtors will have no
liability as to the Republic Action and the Republic Action will be fully
resolved.

                    Philip Services Corporation and Nortru, Inc., Debtors
herein, are defendants in a civil action pending in the United States District
Court for the Western District of Louisiana captioned Kilntech Environmental
Services, Inc. and Rick W. Davenport v. Philip Environmental, Inc. and Nortru,
Inc., Civil Action No. 98-1186-L. Kilntech and Davenport allege, inter alia,
that Philip Services Corporation and Nortru have willfully infringed, and
continue to willfully infringe, certain patents issued to Davenport covering
Davenport's inventions for a fuel

                                       51

<PAGE>   62

blending process that allows for the liquefication of solid hazardous waste and
its dispersion into fuel and the specialized equipment for implementing the fuel
blending process (together, the "Patented Technology"). Kilntech and Davenport
seek damages, including treble damages for willful infringement, and an
injunction permanently enjoining the Debtors from using the Patented Technology.
Additionally, Kilntech and Davenport have filed an administrative claim in the
Debtors' Reorganization Cases requesting payment of an administrative expense
claim of $20 million, plus treble damages, for a total of $60 million, plus
attorneys' fees pursuant to 11 U.S.C. ss. 503(a). Although the Debtors believe
that valid defenses exist to the claims asserted by Kilntech and Davenport, if
the Debtors are unsuccessful in defending against the claims of Kilntech and
Davenport as an administrative liability of the Debtors, the Debtors'
reorganization could be materially and adversely affected and the Debtors' Plan
may not be feasible.

                    PSC is also named as a defendant in several lawsuits which
have arisen in the ordinary course of business. Management believes that none of
these suits is likely to have a material adverse effect on the Debtors' business
or financial condition.

B.       CAPITAL STRUCTURE OF THE DEBTORS

         1.         The Pre-Petition Credit Agreement

                    In August 1997, PSC, PSI and certain of their subsidiaries
entered into a five year term, $1.5 billion revolving credit agreement, which
has been subsequently amended on October 31, 1997, February 19, 1998, June 24,
1998, October 20, 1998 and December 4, 1998 (as amended, the "Pre-Petition
Credit Agreement" and the credit issued thereunder, the "Pre-Petition Credit
Facility") with the Lenders, a syndicate of international lenders including
CIBC, as Administrative Agent, BTCo, as Syndication Agent, CIBC and BTCo as
co-arrangers of credit, Dresdner Bank Canada, Dresdner Bank AG New York Branch
and Royal Bank of Canada as documentation agents, and various other persons from
time to time parties to the Pre-Petition Credit Agreement as lenders. The
Pre-Petition Credit Facility replaced the 1996 revolving term loan agreement,
refinanced certain other long-term debt and was also available for working
capital, capital expenditures and acquisitions. The Pre-Petition Credit
Agreement contained certain restrictive covenants and financial covenants
including that PSC was required to meet specified interest coverage ratio, debt
to EBITDA ratio, fixed charge ratio and working capital ratio tests, and
required PSC to maintain a certain level of working capital.

                    Borrowings under the Pre-Petition Credit Facility are
guaranteed, jointly and severally by certain of PSC's direct and indirect
wholly-owned subsidiaries and are secured by a pledge of all the issued and
outstanding securities of PSC's direct and indirect wholly-owned subsidiaries,
and a charge over substantially all the present and future assets of PSC and its
direct and indirect wholly-owned subsidiaries. The Pre-Petition Credit Facility
bears interest based on a moving grid.

         2.         Recapitalization/Equity

                    Prior to April 30, 1996, PSC's common shares were traded on
the Nasdaq National Market System. Thereafter, PSC's common shares were traded
on the New York Stock Exchange (the "NYSE") under the ticker symbol "PHV" until
January 13, 1999, when the common shares were temporarily halted from trading
due to PSC's failure to comply with the NYSE's continued listing criteria. On
April 23, 1999, the NYSE announced that due to then recent developments in PSC's
financial condition, it would suspend the trading of PSC's common shares
on the NYSE prior to the opening on April 26, 1999, and would seek to delist
those shares. PSC continues to seek to have trading of its common shares on the
NYSE resume, but there can be no assurances that PSC will be able to retain such
a listing. PSC's common shares continue to be listed and posted for trading on
the Toronto Stock Exchange and the Montreal Exchange. There can be no assurance
that PSC will be able to obtain or retain such listing.


                                       52

<PAGE>   63

                    PSC used equity offerings in 1996 and 1997 to fund its
acquisition strategy, as well as pay down the Pre-Petition Credit Facility. In
November 1997, PSC issued 23 million common shares at $16.50 per share. The net
proceeds of $362.5 million were used to repay indebtedness outstanding under the
Pre-Petition Credit Facility. In addition, PSC issued 38.2 million common shares
during 1997 for a total consideration of $622.5 million. The common shares were
issued primarily as a result of acquisitions or as the result of the exercise of
employee stock options. The share capital of PSC increased from $363.1 million
at December 31, 1996 to $1,348.1 million at December 31, 1997.

                    On February 2, 1998, PSC issued 1,381 Common Shares in
connection with the conversion of the Old Debentures assumed by PSC pursuant to
the Allwaste, Inc. acquisition. The transaction was exempt under section 3(a)(9)
of the Securities Act. The number of common shares of PSC outstanding at
November 11, 1998 was 131,144,013.

                    PSC has allotted and reserved 10,257,149 Common Shares under
its 1991 and 1997 Employee Stock Option Plans, the Serv-Tech Long Term Incentive
Plan, and Serv-Tech Amended and Restated 1989 Incentive Stock Option Plan and
the Allwaste Amended and Restated 1989 Replacement Non-Qualified Stock Option
Plan, including any supplements thereto. The stock options permit the purchase
of common shares of PSC at the then current market price. These options
currently expire five to ten years from the date of grant. In addition, PSC has
allotted and reserved 776,386 common shares in conjunction with the acquisition
of Philip Environmental Corporation and the stock options issued thereunder.
These options expire on November 26, 2000.

                    It is also contemplated that the Debtors shall enact a
management options program, subject to the approval of the Bankruptcy Courts in
Canada and the United States and the Lenders, in an effort to retain the current
members of management.

                    Pursuant to the Plan, all allotted and reserved but not
issued Old Common Shares shall be cancelled and terminated on the Effective
Date. In addition, the Old Options are classified in Class 9 under the Plan and
will be cancelled and terminated on the Effective Date.

         3.         Debentures

                    The Old Debentures provided for annual mandatory sinking
fund payments equal to five percent (5%) of the aggregate principal amount of
the Old Debentures issued, commencing June 1, 1999. Interest is payable
semi-annually on June 1 and December 1.

                    PSC's acquisition of Allwaste constituted a 'redemption
event' pursuant to the Allwaste Indenture. Accordingly, each holder of the Old
Debentures had the right to require the redemption of all or any portion of such
holder's Old Debentures for cash to the 90th day following the acquisition.
During the 90-day period, $3.3 million of Old Debentures were redeemed.

                    In conjunction with the merger, on July 30, 1997, PSC,
Allwaste, Inc. and Texas Commerce Trust Co. of New York executed a supplemental
indenture with respect to the Allwaste Indenture (the "First Supplemental
Allwaste Indenture"). The First Supplemental Allwaste Indenture added PSC as
co-obligor on the Allwaste Indenture and transferred conversion rights of
holders of Old Debentures from Allwaste Common Stock to PSC Common Shares. In
addition, the First Supplemental Allwaste Indenture specified that at any time
up to and including June 1, 2014 the holder of any Debenture will have the right
to convert the principal amount of such Old Debenture into PSC Common Shares
equal to the principal amount of the Old Debenture surrendered for conversion
divided by $19.5376. The Old Debentures are redeemable for cash at the option of
PSC at a variable conversion rate as defined in the indenture. On February 2,
1998, PSC issued 1,381 Common Shares in connection with the conversion of the
Old Debentures. The transaction was exempt under section 3(a)(9) of the
Securities Act. The First

                                       53

Supplemental Allwaste Indenture provides that the Old Debentures are
subordinated in priority of payment to the indebtedness owing to the Lenders
under the Pre-Petition Credit Agreement and related documents.

C.       EVENTS CONTRIBUTING TO THE NEED FOR RESTRUCTURING

         1.         Acquisition Strategy and Restatement of Financials

                    PSC commenced 1998 with the objective of integrating the
businesses it had acquired in 1997. The integration was interrupted by a series
of events which occurred in 1998 that had a material impact on PSC and resulted
in it recording a fiscal loss of $1.6 billion in 1998, including special charges
of $1.2 billion.

                    The initial event was the discovery and announcement in
January 1998 of a discrepancy between the book and physical inventory values in
PSC's yard copper business. The announcement of the discrepancy raised serious
questions about the integrity of PSC's accounting and the effectiveness of its
control systems, and had a significant negative impact on PSC's business.
Shortly after the announcement, numerous class action lawsuits and related
claims were commenced against PSC in the United States and Canada. An exhaustive
examination of the discrepancy was conducted by PSC, its auditors and special
counsel to a committee of independent directors of PSC's board of directors. As
a result of these examinations, it was determined that, among other things,
unrecorded losses totaling $92 million arising from unauthorized trading of
copper outside PSC's normal business practices had been incurred. PSC commenced
a civil action against the former president of its metals division and others
engaged in the trading in an effort to recover its losses and reported the
activities to criminal and other appropriate authorities. In light of PSC's
findings, PSC restated its previously reported financial results for 1997, 1996
and 1995. In addition, the staff of the SEC initiated a formal investigation of
the circum stances surrounding the 1997, 1996 and 1995 restatements of PSC's
financial statements. The SEC has advised that its investigation should not be
construed as an indication that any violation of law has occurred, nor should it
be considered a reflection upon any person, entity or security. While PSC
believes it has made all adjustments necessary to its financial statements for
1997, 1996 and 1995, there can be no assurance that additional adjustments will
not be required as a result of the SEC investigation.

                    On February 19, 1998, the Pre-Petition Credit Agreement was
amended to add new covenants regarding adjusted debt and EBITDA ratios and
additional events of default. In connection with the February 1998 amendment to
the Pre-Petition Credit Agreement, on March 16, 1998, PSC and its subsidiaries
that guaranteed the obligations under the Pre-Petition Credit Agreement executed
security agreements whereby each entity granted to the Security Agent for the
benefit of the Lenders a lien upon or security interest in substantially all of
their assets to secure such guarantee obligations and the indebtedness under the
Pre-Petition Credit Agreement.

                    Starting in late 1997 and continuing throughout 1998, there
was a significant deterioration in PSC's copper and ferrous processing
businesses due to the most significant decline in metals prices in over 20
years. PSC's Industrial Services Group failed to achieve its cost reduction
objectives and its by-products business performed weakly, reflecting industry
wide competitive conditions. In addition, declining crude oil prices, which
resulted in deferred maintenance spending by customers with petrochemical
refinery operations, negatively impacted the revenue and profitability of the
Industrial Services Group's operations. PSC reported a first quarter 1998 loss
of $565,000 and a second quarter 1998 loss of $73 million. Various initiatives
were implemented throughout the year in an effort to improve PSC's operating and
financial performance. Management changes were made, including the appointment
of a new Chairman, President and Chief Executive Officer, Chief Financial
Officer, Chief Administrative Officer and Presidents of PSC's Metals Services
and Industrial Services Groups.

                    The deterioration in its principal business segments caused
PSC to violate numerous terms of its then $1.5 billion syndicated Pre-Petition
Credit Agreement. As a result of negotiations with PSC's Lenders, on June 24,
1998, the Pre-Petition Credit Agreement was further amended to reduce the credit
capacity from $1.5 billion to $1.2 billion and increase the interest charged by
100 basis points. The amendment allowed PSC to access $60 million of the
proceeds arising from asset dispositions (of which $20 million was allocated to
provide collateral for

                                       54

<PAGE>   65

letters of credit) instead of having such proceeds applied to reduce outstanding
debt. In return, PSC agreed to a standstill until September 30, 1998 respecting
the incurrence of additional debt and occurrence of dispositions or
acquisitions. By June 30, 1998, PSC was not in compliance with certain
additional terms in the Pre-Petition Credit Agreement, including the financial
covenants which required PSC to maintain a specified interest coverage ratio,
debt to EBITDA ratio, fixed charge ratio and working capital ratio. Because PSC
was not in compliance with the terms of the Pre-Petition Credit Agreement, the
debt outstanding under the Pre-Petition Credit Agreement was classified as a
current liability on PSC's June 30, 1998 Consolidated Balance Sheet.

                    As PSC's operating results deteriorated, questions arose as
to its ability to meet its obligations under the Pre-Petition Credit Agreement
and whether PSC had sufficient available cash to satisfy its working capital and
capital expenditure needs. In the third quarter of 1998, a number of factors,
including a continuing downturn in metal markets, a permanent decline in the
value of investments held by PSC, and the decision to exit certain activities or
locations and to divest of PSC's aluminum and US ferrous operations, caused PSC
to take special charges of $357 million and report a net loss of $645 million.
PSC again made management changes including the appointment in October 1998 of a
new Interim Chief Executive Officer and Chief Restructuring Officer.

                    In connection with the announcement, PSC indicated that its
first priority was to accelerate its ongoing asset disposition and debt
restructuring activities, and refocus its resources on profitable growth. On
October 20, 1998, the Pre-Petition Credit Agreement was further amended to
permit the use of letters of credit under the Pre-Petition Letter of Credit
Facility for general corporate and other purposes and to extend PSC's standstill
on incurrence of additional debt until June 30, 1999. On November 13, 1998, the
same day that PSC announced that it was suspending interest payments on its
Pre-Petition Credit Facility, Carl Icahn, PSC's largest shareholder and debt
holder, together with another lender, announced that they were considering
utilizing involuntary insolvency proceedings to protect their interests unless
PSC met with them to formulate a pre-packaged plan to transfer the ownership and
control of the business to PSC's Lenders. PSC commenced negotiations with Mr.
Icahn and entered into a standstill agreement with him and the other lender on
November 20, 1998. The agreement contemplated a restructuring plan whereby the
debt outstanding under the Credit Agreement would be converted into $200 million
of new secured debt and the distribution of ninety percent (90%) of the equity
of the restructured entity to the Lenders. In accordance with the terms of the
standstill agreement, PSC appointed two new directors nominated by Mr. Icahn to
PSC's board of directors. Also, in November 1998, PSC replaced its then acting
Interim Chief Executive Officer and appointed its Executive Vice Chairman, Allen
Fracassi, as Interim Chief Executive Officer.

                    After discussions with its Lenders, PSC determined that the
restructuring plan contemplated by the November 20, 1998 standstill agreement
would not be approved by the required number of Lenders. PSC presented an
alternative debt restructuring plan to its Lenders on December 15, 1998 which
provided for the conversion of a smaller portion of the debt outstanding under
the Pre-Petition Credit Agreement into equity in an amount to be negotiated with
its lending syndicate.

                    On January 11, 1999, PSC announced that it had negotiated a
term sheet with a sub-committee of the steering committee of its Lenders. The
term sheet set forth the principal terms of a restructuring under a pre-packaged
plan of reorganization. Under the January 11, 1999 term sheet, $550 million of
debt outstanding under the Credit Agreement would be restructured into $350
million of senior secured term debt and $200 million of secured payment in-kind
notes. The balance of the debt outstanding under the Credit Agreement of approxi
mately $550 million would be exchanged for ninety percent (90%) of the common
shares of restructured PSC. The term sheet contemplated the execution of a
Lock-up Agreement with respect to the restructuring. Throughout January,
February and March 1999, PSC continued negotiations with its Lenders in an
effort to obtain an agreement on a plan to restructure PSC.

                    On April 26, 1999, PSC announced that the terms of the
Lock-up Agreement (the "April Lockup Agreement") had been approved by its
Lenders. Under the terms of the April Lock-up Agreement, the then outstanding
secured debt of $1.07 billion would be converted into $300 million of senior
secured debt, $100 million

                                       55

<PAGE>   66

of convertible secured payment-in-kind notes, and ninety percent (90%) of the
common shares of Reorganized PSC. The sale of PUMC (as defined below) on May 8,
1999 resulted in a reduction of the restructured senior debt from $300 million
to $250 million. Pursuant to the Lock-up Agreement, the Lenders, subject to
certain conditions, agreed, among other things, (i) to vote their Lender Claims
in favor of the Plan, (ii) not to oppose confirmation of the Plan, (iii) not to
transfer their Lender Claims except subject to the April Lock-up Agreement, (iv)
to consent to the incurrence of the DIP Facility, the granting of security for
the DIP Facility and subordination of their liens to such security, and (v) to
subordinate the security for the New Secured PIK Debt or New Senior Secured Term
Debt to security for the Exit Facility.

                    The Lenders and PSC also entered into an agreement (the
"Proceeds Agreement") pursuant to which the Lenders agreed to allow PSC access
to the proceeds of certain asset sales for working capital purposes. Between
April 1999 and June 1999, PSC worked to document the restructuring contemplated
by the April Lock-up Agreement with its Lenders. These negotiations and efforts
resulted in an amended and restated Lock-up Agreement dated June 21, 1999 (as
defined previously, the "Lender Lock-up Agreement"). The principal amendments to
the Lender Lock-up Agreement were (a) the elimination of the requirement of a
pre-petition solicitation of the Lenders, (b) an increase in the New Unsecured
PIK Notes to be issued to holders of impaired unsecured claims from $50 million
to $60 million, (c) the approval of the Class 7 Election feature of the Plan,
permitting certain holders of Impaired Unsecured Claims to forego certain of
their New Unsecured PIK Notes for up to $18 million in New Unsecured Convertible
Notes, (d) the addition of an equity distribution of up to five percent (5%) of
the common shares of Reorganized PSC to holders of unsecured claims, (e) the
approval of a settlement reached with counsel for the Securities Claims in the
Securities Actions, and (f) an extension of the timetable to implement the
restructuring through bankruptcy proceedings. Pursuant to the Lender Lock-up
Agreement, holders in excess of seventy-six percent (76%) of the amount of the
syndicated lender debt and more than fifty percent (50%) in number of such
Lenders, have agreed, subject to the terms of the agreement, to vote for and
support the Plan and the Canadian Reorganization Plan. The Lender Lock-up
Agreement contemplates a timely completion of the restructuring in accordance
with the following schedule:

         - Approval of a Disclosure Statement for the Plan by August 31, 1999

         - Confirmation of the Plan by October 31, 1999; and

         - Consummation of the Plan transactions and emergence from Chapter 11
         and CCAA proceedings by November 30, 1999.

                    Failure to achieve any of these events within fifteen (15)
days of the specified deadline constitutes a "Termination Event" under the
Lender Lock-up Agreement. Upon the occurrence of any Termination Event, each
Lender may change or withdraw any votes cast in favor of the Plan and the Lender
Lock-up Agreement may be terminated, upon election, by Lenders holding in the
aggregate at least fifty-one percent (51%) of the aggregate amount of claims
held by the Lenders party to the Lender Lock-up Agreement. As of the date of
this Amended Disclosure Statement, the Debtors had failed to achieve approval of
a Disclosure Statement by the date required in the Lender Lock-Up Agreement.
Accordingly, a "Termination Event" has occurred and the Debtors are in default
under the Lender Lock-Up Agreement.

         2.         Discontinued Operations and Divestitures

                    In 1998, in an effort to further implement the restructuring
effort, the Debtors undertook to review the divestiture of certain of its
businesses and investments. In June of 1998, PSC announced its intention to sell
its ferrous and non-ferrous operations and various non-core assets in order to
reduce and restructure its debt. However, weak ferrous market conditions lowered
the value of the remaining assets and PSC subsequently determined that it would
not proceed with the sale of its ferrous businesses.

                                       56

<PAGE>   67
                    On May 21, 1998, PSC sold certain of its spiral weld
pipe operation for a purchase price of $3.9 million.

                    On July 7, 1998, PSC's Houston, Texas based steel
distribution business was sold for cash proceeds of $95 million, resulting in a
gain on sale of approximately $17 million. The results of operations for the
steel distribution business are included in the Ferrous operations segment of
the Metal Services business. The business generated annual revenue in excess of
$130 million and income from operations of $12.5 million in 1997.

                    During the fourth quarter of 1998, PSC divested of its
minority interest in Strategic Holdings Inc. for approximately $6.6 million. In
December 1998, PSC made the decision to discontinue the Non-Ferrous and Copper
Operations of its Metals Services business. A sale of certain of the aluminum
operations included in Non-Ferrous Operations closed on January 11, 1999 for a
total consideration of approximately $69.5 million.

                    On May 18, 1999, PSC announced that it closed the sale of
its sixty-eight percent (68%) interest in Philip Utilities Management
Corporation ("PUMC") for approximately $70 million. The net proceeds of this
disposition were used to pay down existing indebtedness to the Lenders under the
Pre-Petition Credit Agreement in accordance with the terms of the Lock-up
Agreement.

                    On May 26, 1999, PSC closed the sale of its Conversion
Resources operations in Bedford, Ohio for $529,610.

                    In addition, on May 31, 1999, PSC closed the sale of the
operations and the working capital of its Birmingham Excavation Company
Subsidiary, Philip/BEC, Inc. ("BEC"). The sale generated total proceeds of $20.9
million. The net proceeds of this disposition were deposited in the Proceeds
Account and were subject to the Proceeds Agreement and are now subject to the
Cash Collateral Order.

                    On June 1, 1999, Philip Metals, Inc., one of the Debtors,
sold certain real estate owned by it located in Brook Park, Ohio for $8.5
million to Park Place, Inc. The net proceeds from the sale of this real estate
(approximately $7.9 million) were deposited in the Proceeds Account and were
subject to the Proceeds Agreement and are now subject to the Cash Collateral
Order.

                    On June 8, 1999, Philip Enterprises Inc., a wholly-owned
subsidiary of PSC, entered into an Asset Purchase Agreement whereby it agreed to
sell its Montreal East transfer station and related industrial services
operations for a purchase price of $3.2 million Canadian Dollars, payable forty
percent (40%) at closing, thirty percent (30%) six months post-closing, and
thirty percent (30%) twelve months post-closing.

         3.         Employee Retention Program

                    PSC is in the process of formulating an employee retention
program to allow the Debtors to retain approximately 150 of its key employees in
light of the restructuring of PSC this year, pending approval by the board of
directors and the Lenders. However, the cost of such program has been estimated
in the financial projections of the Plan. PSC is examining its employees'
contributions to the company during the year and determining which employees are
invaluable to the Debtors successful restructuring. In order to retain these key
employees, PSC is developing a bonus program in which the key employees, upon
their continued employment, receive a bonus, depending upon the employee's
position in the company, based on a percentage of their base salary. Payments
under the program will be staggered up to June 30, 2000. PSC is also formulating
an executive retention bonus program pending approval by the board of directors
and Lenders. The Program will provide that the key executives will receive a
retention bonus based on a portion of their salary. Payments under the program
will be staggered up to September 2000.

         4.         Negotiations with Unsecured Creditors

                    In February 1999, the Indenture Trustee for the Old
Debentures informed PSC that an ad hoc committee of holders of Old Debentures
had formed to represent the interest of holders of Old Debentures in connection
with the restructuring. The Indenture Trustee retained counsel to represent the
Indenture Trustee in connection with the restructuring. The Debtors had an
initial meeting with the ad hoc committee of Old Debenture holders and the
Indenture Trustee in February 1999, wherein the Debtors outlined the proposed
restructuring. After that meeting, the Debtors entered into confidentiality
agreements with the Indenture Trustee and members of the ad hoc committee and
provided certain requested information relating to the restructuring. The
Indenture Trustee also retained a financial advisor to assist in the
restructuring negotiations.

                    During April, May and June 1999, the Debtors had several
meetings and conference calls with the Indenture Trustee, its counsel and
financial advisor in regard to the terms of the restructuring. The Debtors have
also conducted negotiations with certain other large holders of Impaired
Unsecured Claims, including CIBC and Republic. Those negotiations began in early
1999 and have continued through June 1999.

         5.         Other Pre-Petition Settlement Negotiations

                    In connection with the restructuring, prior to the Petition
Date, PSC attempted to resolve various parties' claims. PSC has succeeded in
resolving certain claims including various severance claims in an amount of
$290,000 to three former senior executives to settle severance obligations
totaling $1.7 million. In addition, one former senior executive is entitled to
receive bi-weekly severance payments totaling $138,000 over a 30 week period to
settle a severance obligation of $960,000. Of the $10.8 million in current
severance obligations to senior executives, PSC has negotiated settlements
totaling approximately $242,000 with 5 senior executives to reduce the company's
severance obligations by $1.1 million.

                    On April 16, 1999, PSC settled a lease obligation with
Mellon Bank, N.A. for a payment of approximately $152,000, representing two
months rent. The lease, which would have expired in November 2002, related to
vacant office space in Pennsylvania, which previously held the PSC's U.S.
corporate headquarters.

                    Certain litigation was settled by PSC over the past year.
The settlements include the case of National Copper & Smelting v. Allworth in
which National Copper claimed that the trichloroethylene it purchased from
Allworth was contaminated causing National Copper's machine damage. The case was
settled in an amount less than expected legal fees for the defense. The second
case settled was U.S. Environmental Protection Agency v. Solvent Recovery
Corporation. This case concerned a June 19, 1998 complaint by the EPA alleging
three violations of federal law. The Debtors settled the complaint by agreement
to pay $4,000 in fines. A third settlement concerned Remry v. Allwaste
Environmental Services wherein the Plaintiff, a former PSC employee, succeeded
on his claim of a bonus under the employee incentive program in effect from
September through December 1996.

                    On June 23, 1999, the Debtors entered into a settlement
agreement with GalvPro L.P. pursuant to which the Debtors paid $2,000,000 in
exchange for complete, valid and binding mutual releases arising from or in any
way relating to either party's performance under a certain Design/Build
Agreement dated March 9, 1998 and entered into by D&L Corp. and GalvPro.

                CORPORATE STRUCTURE AND MANAGEMENT OF THE DEBTORS

A.       CURRENT CORPORATE STRUCTURE

         PSC was amalgamated under the laws of the Province of Ontario as Philip
Environmental Inc. pursuant to a Certificate and Articles of Amalgamation dated
April 15, 1991. On May 22, 1997, a Certificate and Articles of Amendment under
the Business Corporations Act (Ontario) were issued changing the name from
Philip Environ mental Inc. to Philip Services Corp.

         PSC is a holding company with over 200 wholly-owned Subsidiaries in
Canada, the United States, Barbados, and throughout Europe. The Debtors,
together with the aforementioned Subsidiaries, their wholly and majority-owned
Subsidiaries, and their direct and indirect Subsidiaries, consist of over 200
corporations, limited liability companies, partnerships, limited partnerships
and other forms of business entities. The Debtors' primary base of operation is
in the United States.

         PSI is a corporation established in the United States under the laws of
the State of Delaware. PSI is a wholly-owned direct subsidiary of Philip
Enterprises Inc., a Canadian company, which in turn is wholly-owned directly by
PSC.

         A more complete description of the Debtors' current corporate structure
including the relationship of PSC and PSI to the Subsidiary Debtors, presented
in organizational chart form, is presented in Appendix B to the Disclosure
Statement. The Appendix also includes an organizational chart showing the
anticipated corporate structure of the Debtors and the Subsidiaries if the
Alternate Canadian Transactions are implemented.

<PAGE>   72

         Mr. Fernandes is employed as President and Chief Executive Officer of
the Debtors and his employment has been approved by the Bankruptcy Courts in
Canada and the United States. Mr. Fernandes replaced Mr. Allen Fracassi,
co-founder of Philip Services, who was the CEO of PSC for over 18 years. Mr.
Fracassi will assist in providing an orderly transition in leadership.

         Mr. Fernandes has over thirty years of management experience with
Atlantic Richfield Company ("ARCO"), and is eminently qualified to assume the
position of CEO. More importantly, Mr. Fernandes has valuable experience in a
variety of turn-around situations. Most recently, Mr. Fernandes served as
Executive Vice President and a member of the board of directors of ARCO, where
he participated in or ran a wide variety of businesses including metals and
mining, chemicals, pipelines, as well as an environmental remediation group.
Notably, although many of these operations initially were troubled, Mr.
Fernandes managed to transform them into productive and profitable operations.

         As Executive Vice President, Mr. Fernandes reported directly to the
chief executive officer of ARCO, and was responsible for a number of diverse
operations in non-oil exploration and producing activities with a total revenue
of approximately $10 billion. Mr. Fernandes has recently been elected to the
board of directors of Lubricants Specialty Company, and is currently on the
board of directors of Black & Veatch, a Kansas City-based engineering company.

         The salient terms of the employment agreement between Mr. Fernandes and
PSC are as follows:

         1.         Mr. Fernandes will serve an initial two year term (which
                    shall automatically renew for addi tional one year terms
                    unless PSC provides thirty (30) days notice of nonrenewal),
                    report to the board of directors of PSC, and exercise such
                    powers as may from time to time be assigned or vested in him
                    by the board of directors of PSC, including, inter alia,
                    leadership of the efforts of PSC in achieving business plans
                    as may be in effect.

         2.         Mr. Fernandes will receive an annual base salary of $500,000
                    (U.S.) (the "Base Salary").  Under certain circumstances,
                    an annual bonus of up to $500,000 (U.S.) will be paid to
                    Mr. Fernandes. The salary and available bonus payments to
                    Mr. Fernandes reflect his unique knowledge of and
                    experience with the Debtors' businesses and the vital
                    role he will play in the Debtors' restructuring efforts
                    and thereafter.

         3.         On the Grant Date (as defined in the proposed employment
                    agreement), subject to Toronto Stock Exchange approval, Mr.
                    Fernandes shall be granted three groups of options in
                    respect of that number of common shares of PSC equal to: (i)
                    two percent (2%) ("Group I"), (ii) one
                    percent (1%) ("Group II"), and (iii) one percent (1%)
                    ("Group III"), of the total number of common shares of PSC
                    issued and outstanding at the time of the conclusion of
                    these Chapter 11 Cases, after giving effect to the exercise
                    of all of Mr. Fernandes' options (whether or not actually
                    exercised). The strike price shall be the Base Option Price
                    (as defined in the employ ment agreement) for Group I, 125
                    percent of the Base Option Price for Group II, and 145.8
                    percent of the Base Option Price for Group III. Subject to
                    the other terms of the employment agreement, the options
                    shall become exercisable as follows: the Group I options
                    shall become vested fifty percent (50%) on each of the first
                    and second anniversaries of the Grant Date, the Group II
                    options shall become vested on the third anniversary of the
                    Grant Date, and the Group III options shall become vested on
                    the fourth anniversary of the Grant Date; and all unvested
                    options will immediately vest in the event of a change of
                    control of PSC (as defined in the employment agreement).
                    Additionally, at the conclusion of these Chapter 11 Cases,
                    Mr. Fernandes may purchase up to $250,000 (U.S.) of common
                    shares of PSC at the per-share reorganized equity value of
                    PSC as described in the employment agreement.

D.       DIRECTORS AND OFFICERS OF THE REORGANIZED DEBTORS

         Subject to the requirements of section 1129(a)(5) of the Bankruptcy
Code, the Debtors intend to announce prior to the Confirmation Date the
identities of the individuals proposed to serve as officers of the Reorganized
Debtors and the directors of Reorganized PSC (if the Canadian Reorganization
Plan is sanctioned) or Reorganized PSI (if the Alternate Canadian Transactions
are implemented or the Canadian Plan Condition is waived). To the extent
possible, the identities of such individuals will be announced by inclusion of a
list of proposed directors and/or officers in the Plan Supplement, which will be
filed with the Bankruptcy Court at least five (5) Business Days prior to the
commencement of the Confirmation Hearing. The new board of directors for

Reorganized PSI (if the Alternate Canadian Transactions are implemented or if
the Canadian Plan Condition is waived) will consist of nine (9) directors, who
will be nominated by holders of Lender Claims. The nominees of the holders of
Lender Claims shall include two (2) members of the existing PSC board of
directors and will include two (2) members nominated by High River Limited

existing board of directors. It is anticipated that Mr. Fernandes will be

Alternative Canadian Transactions occur).

E.       UNAUDITED PROJECTED FINANCIAL INFORMATION AND BUSINESS AND OPERATING
         STRATEGIES

         The Debtors' new business plan (around which the plan of reorganization
was developed) provides for the Debtors to exit from Chapter 11 with a new board
of directors and a revised capital structure. Upon emergence from Chapter 11,
the Reorganized Debtors will be more focused and efficient with an enhanced
balance sheet and access to capital pursuant to the Exit Facility, and better
positioned to meet the needs and expectations of the Reorganized Debtors'
customers going forward.

         The terms of the Debtors' new business plan are set forth in greater
detail in the pro forma financial projections contained in Appendix F to the
Disclosure Statement.

                           Use and Other Taxes

                           The Bankruptcy Court confirmed the Debtors' authority
to pay prepetition sales, use and other taxes collected by the Debtors from
their customers or incurred in the ordinary course of their businesses to the
appropriate taxing authorities.

                    (g)    Motion for Authority to Pay Certain Prepetition
                           Shipping, Warehousing and Distribution Charges and
                           Brokers' Fees.

                           The Bankruptcy Court authorized the Debtors to pay
certain prepetition shipping, warehousing and distribution charges and broker's
fees as the Debtors determine, in the exercise of their business judgment, are
necessary or appropriate to obtain and/or ensure the transport, delivery or
release of the Debtors' goods and to satisfy the liens, if any, held by the
shippers, warehouses, distributors or brokers, in respect of such goods.

                    (h)    Motion Confirming Grant of Administrative Expense
                           Status to Obligations Arising From Postpetition
                           Delivery of Goods and For Certain Holders of Valid
                           Reclamation Claims, Prohibiting Third Parties from
                           Interfering with Delivery of Goods to Debtors, and
                           for Authority to Pay Certain Expenses in the Ordinary
                           Course of Business

                           The Bankruptcy Court granted the Debtors' request for
an order confirming that the Debtors' undisputed obligations (arising directly
and indirectly from the shipment or delivery by suppliers and vendors of scrap
metals, chemical by-products, and related items accepted by the Debtors
postpetition) will have administrative expense priority status, granting
administrative expense treatment for certain holders of valid reclamation
claims, and establishing authority to pay certain expenses in the ordinary
course of business.

                    (i)    Motion for Authority to Honor Certain Prepetition
                           Obligations to Customers and to Continue Customer
                           Programs and Practices

                           The Bankruptcy Court authorized the Debtors to honor
certain prepetition customer practices and obligations to customers the Debtors
deem necessary, in the same manner such practices were implemented and such
obligations were honored before the commencement of the Chapter 11 Cases,
including but not limited to customer discounts, credits or deposits, and
certain other contractual obligations.

                    (j)    Motion for Authority to Pay Certain Contractors in
                           Satisfaction of Perfected or Potential Mechanics',
                           Materialmen's, or Similar Liens and Interests in the
                           Ordinary Course of Business

                           The Bankruptcy Court authorized the Debtors to pay
certain prepetition obligations owed to mechanics, materialmen and other such
entities potentially holding liens that the Debtors deem necessary, including
but not limited to certain contractors in satisfaction of perfected or potential
liens and interests.

                    (k)    Motion Authorizing Payment of Certain Prepetition
                           Claims of Key Trade Vendors

                           The Bankruptcy Court authorized the Debtors, as may
be appropriate, to pay prepetition claims of vendors who agree to provide
continuing trade credit on the terms provided prepetition to the Debtors.

                    (l)    Motion Authorizing Debtors to Obtain Postpetition
                           Surety Bonds and to Enter Indemnity Agreement and
                           Inter-Creditor Agreement

                           The Debtors sought and obtained a stipulation and
order from the Bankruptcy Court authorizing the Debtors to obtain postpetition
surety bonds and to enter approved indemnity agreements dated as of June 28,
1999 and an approved inter-creditor agreement dated June 28, 1999 regarding the
treatment of the obligations of the Debtors with respect to bonds the ("Bonding
Lien Order"). The indemnity agreement generally provides that the Debtors shall
indemnify the parties to the indemnity agreement from any loss, cost, and damage
from the failure of the Debtors to perform obligations, including reimbursement
obligations, and grants security interests in assets related to bonded projects.
The Bonding Lien Order and the intercreditor agreements established

                                       66

<PAGE>   77

the priority of the surety participant's security and claims. The Debtors
anticipate that the surety bonds will remain in place post-confirmation on the
same terms.

                    (m)    Motion Approving Stipulation and Order Authorizing
                           and Restricting Debtors' Use of Cash Collateral and
                           Granting Adequate Protection

                           The Bankruptcy Court granted the Debtors' request for
an order approving a stipulation and order authorizing and restricting the
Debtors' use of cash collateral and granting adequate protection of certain
secured claims. Pursuant to the terms of the stipulation and order, the Debtors
were granted permission to use the cash collateral on a consensual and
negotiated basis, and adequate protection was granted to prepetition lenders and
holders of certain liens.

                    (n)    Motion Approving Cross-Border Insolvency Protocol

                           The Bankruptcy Court approved the Debtors' proposed
protocol between the United States Bankruptcy Court for the District of Delaware
and the Ontario Superior Court of Justice to govern the resolution of
administrative issues anticipated to arise in coordinating the insolvency
proceedings. This protocol is designed to coordinate activities in the two
insolvency proceedings, protect the rights of parties thereto, and ensure the
maintenance of each court's jurisdiction and comity.

                    (o)    Motion Establishing Disclosure Statement Hearing
                           Date, a Confirmation Hearing Date, and Certain
                           Other Critical Dates

                           The Bankruptcy Court granted the Debtors' request for
an expeditious confirmation timetable, scheduling hearings on the approval of
the Disclosure Statement for August 23, 1999 and confirmation of the Plan on
October 13, 1999 respectively. These dates were continued to September 21, 1999
and November 3, 1999, respectively.

                    (p)    Motion Establishing Bar Date for Filing Proofs of
                           Impaired Unsecured Claims and Approving Forms and
                           Manner of Notice Thereof

                           The Bankruptcy Court approved the Debtors' proposed
form and manner of notice of the Bar Date and authorized the Debtors to provide
such notice, along with a Proof of Claim form, to all parties listed on a
certain impaired unsecured creditors list.

         2.         Appointment of Official Committee of Unsecured Creditors

                    On July 12, 1999, the Office of the United States Trustee
appointed seven members to the official committee of unsecured creditors (the
"Official Committee") to represent the interests of unsecured creditors of the
Debtors. Since its formation, the Debtors have consulted with the Official
Committee concerning the administration of the Chapter 11 Cases. The Debtors
have kept the Official Committee informed about their operations and have sought
the concurrence of the Official Committee for actions and transactions taken
outside of the ordinary course of the Debtors' business. The Official Committee
has participated actively, together with the Debtors' management and
professionals, in connection with negotiation of the Plan.

                    The Official Committee consists of seven members: the U.S.
Trustee, Great Plains Trust Company, Kornitzer Capital Management, Inc.,
Republic Environmental Systems, Inc., Siemens Westinghouse Power Corporation,
Plasma Processing Corporation and Mr. Robert M. Chiste. Counsel to the Official
Committee is Blank Rome Comisky & McCauley, LLP, One Logan Square, Philadelphia,
PA 19103-6998, Attention: Raymond L. Shapiro, Esq. and the Creditors'
Committee's Financial Advisor is Loeb Partners Corporation, 61 Broadway, 24th
Floor, New York, New York, 10006, Attention: Harvey Tepner. Canadian counsel to
the Official Committee is

                                       67

<PAGE>   78

Cassels, Brock & Blackwell, Scotia Plaza, Suite 2100, 40 King Street West,
Toronto, Ontario, M5H 3C2, Attention: E.B. Leonard.

                    After the Confirmation Date, the Creditors' Committee shall
continue to exist as provided in this paragraph and shall be an active
participant in the Claims review process. The Creditors' Committee shall have
the right to file objections to Class 7 Claims and, if the Canadian
Reorganization Plan is sanctioned, Canadian Impaired Unsecured Claims. The
Creditors' Committee shall be reduced to three members as they shall select and
be represented by counsel and other professionals retained by the Committee
prior to the Effective Date ("Commit tee Professional"). Until all Distributions
to Class 7 Claims have been made pursuant to Plan, the Creditors' Committee will
continue to exist and may: (i) file such pleadings with the Bankruptcy Court as
it deems appropriate or necessary concerning implementation of the Plan; (ii)
consult with the Reorganized Debtors concerning objections to, settlements of or
litigation over Disputed Class 7 Claims; (iii) monitor, analyze and reconcile
the Distributions to holders of Class 7 Claims; and (iv) provide such other
services that the Creditors' Committee deems reasonably necessary to protect and
enforce the rights and interests of the holders of Class 7 Claims consistent
with the provisions of the Plan. Following the Effective Date, the reasonable
out of pocket fees and expenses of all Committee Professionals, and the expenses
of Committee members, shall be paid by the Reorganized Debtors within ten days
after receipt of monthly invoices from such Committee Professionals, provided,
however, that the Reorganized Debtors shall be entitled to dispute the
reasonableness of any such fees and expenses and further provided that the
Reorganized Debtors' aggregate liability for post-Confirmation fees and expenses
of the Creditors' Committee and the Creditors' Committee professionals shall not
exceed $50,000 in the event the Canadian Reorganization Plan is sanctioned, and
$75,000 in the event the Alternate Canadian Transactions are implemented. Any
unresolved, disputed fees and expenses shall be presented to the Bankruptcy
Court for resolution. If the Canadian Reorganization Plan is sanctioned, the
Creditors' Committee shall be entitled to retain Canadian counsel, which may
incur post-confirmation fees and expenses payable by the Reorganized Debtors up
to an aggregate $50,000.

         3.         Other Matters Occurring in the Cases

                    (a)    Motion Authorizing Employment of Loeb Partners
                           Corporation As Financial Advisor and Investment
                           Banker For The Official Committee Of Unsecured
                           Creditors

                           The Bankruptcy Court authorized the Official
Committee of Unsecured Creditors of the to employ Loeb Partners Corporation as
its investment banker and financial advisor in these Chapter 11 Cases,
effective as of July 15, 1999.

                    (b)    Motion Authorizing the Debtors to Enter Into An
                           Employment Agreement with Mr. Anthony G. Fernandes
                           as Chief Executive Officer of PSC

                           On September 14, 1999, the Bankruptcy Court approved
Debtors' motion to enter into an employment agreement and retain Mr. Anthony G.
Fernandes as Chief Executive Officer of PSC.

                    (c)    Motion for an Order Authorizing Substantive
                           Consolidation of Debtors For Purposes of the
                           Treatment of Classes 6, 7 and 8 Under the Plan

                           On August 9, 1999, the Debtors filed a motion for an
order substantive consolidation of the Debtors for purposes of the
treatment of Classes 6, 7 and 8 under the Plan, including for the purposes of
voting, confirmation and distribution (the "Substantive Consolidation Motion").
The Debtors expect to have the Substantive Consolidation Motion heard at the
same time as the hearing on the confirmation of the Plan.

         4.         Negotiations with Allen Fracassi


                                       68

<PAGE>   79

                    PSC is also contemplating entering into a consulting
agreement with Do 4 U Services Corporation whereby Do 4 U Services Corporation
will provide certain management consulting services for up to seventy-five (75)
hours per month of a nature set out in the consulting agreement. Such consulting
services shall be provided for a twelve (12) month period by and/or through
Allen Fracassi or other selected individuals in consideration of a set monthly
fee, including reasonable out of pocket expenses.

                    In consideration of PSC entering into the aforementioned
consulting agreement, Mr. Fracassi and PSC shall enter into a settlement
agreement which sets out the terms and conditions of the settlement of all
outstanding claims of Mr. Fracassi arising from his employment or the cessation
of his employment by PSC, which settlement agreement is in lieu of and not in
addition to any other entitlements of Mr. Fracassi. Further, as more fully
described in the settlement agreement, Mr. Fracassi shall forever release and
discharge PSC from any and all claims now or hereafter existing arising from any
event relating to Mr. Fracassi's employment or the cessation of such employment
with PSC. In consideration of Mr. Fracassi entering into the settlement
agreement and complying with its terms, PSC shall forever release and discharge
all claims held by it based on any actions relating to Mr. Fracassi except for:
(i) Mr. Fracassi's outstanding indebtedness to PSC and (ii) any claims which
would be Excluded Indemnification Obligations, as subject to revocation by PSC
in the event PSC reasonably determines that Mr. Fracassi has failed to provide
factual information to PSC in connection with any claim against Deloitte &
Touche and Robert Waxman arising out of the same nucleus of operative facts
alleged in the Securities Actions, the Chazen Actions or the Liff Actions.

         5.         Management Stock Options Plan

                    On the Effective Date, as soon thereafter as is reasonably
practical thereafter, Reorganized PSC, if the Canadian Reorganization Plan is
sanctioned, or Reorganized PSI, if the Alternate Canadian Transactions are
implemented, will adopt and implement a Management Stock Option Plan. Pursuant
to the proposed Management Stock Option Plan, between three and three and
one-half percent (3 and 3.5%) of the New Common Shares or Reorganized PSI Common
Shares, as applicable will be made available in the form of stock options
pursuant to the terms of the Management Stock Option Plan to senior executives
of the Reorganized Debtors other than Anthony Fernandes. The terms of the
Management Stock Option Plan have not been finalized at this time and are
currently being negotiated between the Debtors and the Lenders. A copy of the
Management Stock Option Plan will be provided in the Plan Supplement.

B.       POST-PETITION OPERATIONS AND LIQUIDITY

         On June 28, 1999, the Bankruptcy Court entered an interim order
authorizing the Debtors to obtain secured postpetition financing up to an
aggregate principal amount not to exceed $100 million from certain lenders, to
obtain on an interim basis $12 million in letter of credit capacity pending
final relief, granting the lenders security interests in all the Debtors'
presently owned and after-acquired property to secure the Debtors' obligations
under the DIP Credit Agreement subject to a carve-out, and granting the lenders
priority with respect to the Debtors' obligations over any and all
administrative expenses of the kinds specified in sections 503(b) and 507(b) of
the Bankruptcy Code, subject to a carve-out and certain other superpriority
claims expressly set forth in the DIP Credit Agreement. On July 27, 1999, the
Bankruptcy Court entered the Final Order authorizing the Debtors to obtain
secured postpetition financing.

C.       THE COMPANIES' CREDITORS ARRANGEMENT ACT (THE "CCAA") OF CANADA

         As previously stated, PSC is amalgamated under the laws of the Province
of Ontario and PSI is a corporation established in the United States under the
laws of the State of Delaware.

         On June 25, 1999, PSC and twenty-five of its Canadian subsidiaries (the
"Canadian Debtors") commenced a case under the Companies' Creditors Arrangement
Act (the "CCAA") of Canada in the Ontario Superior Court of

                                       69

<PAGE>   80

Justice (the "Ontario Court"). The CCAA is intended to facilitate the
reorganization of major public companies with complicated public debt structures
and is the most effective framework for financial restructuring in Canada.

         CCAA protection is not automatic but depends on the discretion of the
court. Where the court grants protection under the CCAA, a general stay of
proceedings normally is imposed against any and all proceedings and claims. An
initial stay of proceedings is restricted by statute to a maximum period of 30
days. The applicant may apply to extend the stay of proceedings and the court
normally will extend the stay if the court is satisfied that constructive
negotiations for the reorganization are taking place.

         The purpose of the commencement of the Canadian Cases for PSC and the
Canadian Debtors was to obtain a stay of proceedings in order to permit the
restructuring contemplated by the Plan. The Debtors intend to seek court
approval in the Canadian Cases of the Canadian Reorganization Plan or the
Alternate Canadian Transactions.

         For the Canadian Reorganization Plan to be sanctioned, the Canadian
Reorganization Plan must receive the affirmative vote of two-thirds in value of
proven claims and a majority in number of creditors holding proven claims in
each class of creditors entitled to vote. Holders of Lender Claims against the
Canadian Debtors, and the class of holders of Canadian Impaired Unsecured Claims
(similar to Class 7 of the Plan) will have the right to vote on the Canadian
Reorganization Plan. Subject to the terms of the Lender Lock-up Agreement, the
Lenders have agreed to vote in favor of the Canadian Reorganization Plan. If the
class of holders of Canadian Impaired Unsecured Claims votes to reject the
Canadian Reorganization Plan, then the Canadian Reorganization Plan cannot be
sanctioned.

         On August 27, 1999, the Canadian Court required certain amendments to
the Canadian Reorganization Plan to be effected in order for Claims against PSC
to be proven and governed by the Canadian Reorganization Plan as well. The
Debtors have, in accordance with the Canadian Court's order, so amended the
Canadian Reorganiza tion Plan. However, in the event Canadian creditors that
may, as a result of such amendments, have the right to vote to approve the
Canadian Reorganization Plan, do not waive such right to or otherwise enter into
a settlement arrangement acceptable to the Debtors, the Canadian Debtors and the
Lenders, the Alternate Canadian Transactions may be implemented

         While the sanctioning of the Canadian Reorganization Plan is a
condition to the Effective Date of the Plan, that condition may be waived,
enabling the Plan to be confirmed before the outcome of the Canadian proceedings
is determined. In such case, (a) all New Securities shall be issued by
Reorganized PSI, (b) PSC and the other Canadian Debtors will continue to be
managed by PSC's current Board of Directors and current management and (c) until
either the Canadian Reorganization Plan is sanctioned or the Alternate Canadian
Transactions are imple mented, all assets of PSC and the other Canadian Debtors
will continue to be owned and operated by PSC and the other Canadian Debtors,
respectively. If the Canadian Plan Condition is waived, it is contemplated that
substan tially all equity interests and/or assets of PSC and the other Canadian
Debtors ultimately will be transferred as going concerns to one or more direct
or indirect subsidiaries of Reorganized PSI.

         Previously, on June 25, 1999, the Ontario Court issued an initial order
(the "Initial Order") in connection with the Canadian Cases. The following
provides a summary of certain of the matters addressed in the Initial Order:

         1.         Stay of Proceedings

                    The Ontario Court ordered that until Friday, July 23, 1999,
all proceedings against the Canadian Debtors are stayed and suspended and all
persons with contractual arrangements with the Canadian Debtors for the supply
of goods and services are restrained from asserting remedies contractual or
otherwise, against the Canadian Debtors.

         2.         Payment of Trade Creditors

                                       70

<PAGE>   81

                    The Ontario Court ordered that the Canadian Debtors shall be
authorized to continue to pay claims of trade creditors, whether incurred before
or after the Initial Order provided that with respect to claims in excess of
$2,000, such trade creditors continue to supply trade credit to the Canadian
Debtors on terms at least as favorable as those currently extended.

         3.         Operations

                    The Ontario Court ordered that the Canadian Debtors remain
in possession and control of their property and to carry on business in a manner
consistent with the preservation of the Canadian Debtors' business and property
and to continue to engage advisors in the ordinary course of business or in
connection with the CCAA restructuring.

         4.         Authority to Borrow and Charging of Property

                    The Ontario Court ordered that the Canadian Debtors are
authorized and directed to enter into the DIP Facility and the matters referred
to above in sections VI.A.1(l) and (m).

         5.         Appointment of Ernst and Young Inc. as Monitor

                    The Ontario Court ordered that Ernst & Young Inc. (the
"Monitor") is appointed as the Monitor to monitor the business and affairs of
the Canadian Debtors during the Canadian Proceedings in accordance with the
statutory rights and obligations of monitors set forth in the CCAA and the
specific rights and obligations set forth in the Initial Order.

         6.         Cross-Border Insolvency Protocol

                    The Ontario Court approved the Canadian Debtors' proposed
protocol between the United States Bankruptcy court for the District of Delaware
and the Ontario Superior Court of Justice referred to above in section
VI.A.1(n).


                                  ARTICLE VII.

                        CERTAIN FACTORS TO BE CONSIDERED

         Holders of Class 6 and 7 Claims should carefully consider the following
factors, as well as the other information set forth in this Disclosure Statement
(and the documents delivered together herewith and/or incorporated by reference
herein), before deciding whether to vote to accept or to reject the Plan.

A.       GENERAL CONSIDERATIONS

         The formulation of a plan of reorganization is the principal purpose of
the Chapter 11 Cases. The Plan sets forth the means for satisfying the Claims
against the Debtors. Certain Claims and Interests receive no distributions
pursuant to the Plan. See Article II.C of the Disclosure Statement, entitled
"Summary of the Plan of Reorganization -- Classification and Treatment of Claims
and Interests." Reorganization of the Debtors' businesses and operations under
the proposed Plan also avoids the potentially adverse impact of a liquidation on
the Debtors' employees, and many of their customers, trade creditors and
lessors.

                                       71

<PAGE>   82

B.       CERTAIN BANKRUPTCY/CCAA CONSIDERATIONS

         1.         General

                    The filing of bankruptcy petitions by the Debtors and the
publicity attendant thereto may adversely affect the Debtors' businesses. The
Debtors believe that any such adverse effects may be diminished by the support
of the consenting lenders for the Plan pursuant to the terms of the Lender
Lock-up Agreement and the proposed timetable for the cases. However, such
adverse affects are likely to be experienced during the pendency of a protracted
bankruptcy case.

         2.         Effect on Non-Filing Subsidiaries

                    Together, the Chapter 11 Cases and the CCAA proceedings have
captured most, but not all of PSC's Subsidiaries in North America. For complete
lists of entities seeking Chapter 11 and CCAA relief, see Exhibit A to the Plan
and Appendix C hereto. There are, however, certain United States, Canadian, and
other international Subsidiaries that have not sought either Chapter 11 or CCAA
protection.

                    The filing of the Chapter 11 Cases by the Debtors and the
publicity attendant thereto might also adversely affect the businesses of any
non-filing Subsidiaries. Because the business of PSC is closely related to the
businesses of all its Subsidiaries, any downturn in the businesses of non-filing
Subsidiaries could affect PSC's prospects also. Although PSC does not believe
that the commencement of these Chapter 11 Cases will adversely affect the
businesses of any non-filing Subsidiaries, if the Chapter 11 Cases become
protracted, the possibility of adverse effects on such non-filing Subsidiaries
may increase.

         3.         Failure to Confirm the Plan

                    Even if all Impaired voting classes vote in favor of the
Plan and, with respect to any Impaired Class deemed to have rejected the Plan
the requirements for "cramdown" are met, the Bankruptcy Court, which, as a court
of equity may exercise substantial discretion, may choose not to confirm the
Plan. Section 1129 of the Bankruptcy Code requires, among other things, a
showing that confirmation of the Plan will not be followed by liquidation or the
need for further financial reorganization of the Debtors, see Article XI.A of
the Disclosure Statement, entitled "Feasibility of the Plan and the Best
Interests of Creditors Test -- Feasibility of the Plan," and that the value of
distributions to dissenting holders of Claims and Interests may not be less than
the value such holders would receive if the Debtors were liquidated under
Chapter 7 of the Bankruptcy Code. (See Article XI.C of the Disclosure Statement,
entitled "Feasibility of the Plan and the Best Interests of Creditors Tests --
Best Interests Test.") Although the Debtors believe that the Plan will meet such
tests, there can be no assurance that the Bankruptcy Court will reach the same
conclusion.

         4.         Failure to Consummate the Plan

                    The Plan provides for certain conditions that must be
fulfilled prior to confirmation of the Plan and the Effective Date. As of the
date of this Disclosure Statement, there can be no assurance that any or all of
the conditions in the Plan will be met (or waived) or that the other conditions
to consummation, if any, will be satisfied. Accordingly, even if the Plan is
confirmed by the Bankruptcy Court, there can be no assurance that the Plan will
be consummated and the restructuring completed. Additionally, it is a condition
to the Effective Date of the Plan that the Canadian Reorganization Plan is
sanctioned. If this condition is waived it is possible that the Plan may become
Effective prior to the consummation of either the Canadian Reorganization Plan
or the Alternate Canadian Transactions. In such case distributions under the
Plan to Classes 8B and 8C and any Class 6 Additional Distributions will be
delayed pending a resolution of the Canadian proceedings.

                                       72

         5.         Certain Provisions of the Amended Certificate of
                    Incorporation, the By-Laws and Other Agreements

                    The Amended Certificate of Incorporation, the By-Laws and
certain other agreements contain provisions that may have the effect of
delaying, deferring or preventing a change in control of the Reorganized
Debtors.

C.       CERTAIN TAX CONSIDERATIONS

         THERE ARE A NUMBER OF MATERIAL INCOME TAX CONSIDERATIONS, RISKS AND
UNCERTAINTIES ASSOCIATED WITH CONSUMMATION OF THE PLAN. INTERESTED PARTIES
SHOULD READ CAREFULLY THE DISCUSSION SET FORTH IN ARTICLE X OF THE DISCLOSURE
STATEMENT, ENTITLED "CERTAIN UNITED STATES INCOME TAX CONSEQUENCES OF THE PLAN"
FOR A DISCUSSION OF THE MATERIAL FEDERAL INCOME TAX CONSEQUENCES AND RISKS FOR
HOLDERS OF CLAIMS AND THE DEBTORS RESULTING FROM THE TRANSACTIONS OCCURRING IN
CONNECTION WITH THE PLAN.

D.       INHERENT UNCERTAINTY OF FINANCIAL PROJECTIONS

         The Projections set forth in Appendix F hereto cover the
Debtors' operations through the period ending December 31, 2001. These
Projections are based on numerous assumptions that are an integral part of the
Projections, including confirmation and consummation of the Plan in accordance
with its terms, realization of the operating strategy of the Reorganized
Debtors, industry performance, no material changes in applicable legislation or
regulations, exchange rates, or generally accepted accounting principles,
general business and economic conditions, competition, adequate financing,
absence of material contingent or unliquidated litigation or indemnity claims,
and other matters, many of which are beyond the control of the Reorganized
Debtors and some or all of which may not materialize. In addition, unanticipated
events and circumstances occurring subsequent to the date of this Disclosure
Statement may affect the actual financial results of the Reorganized Debtors'
operations. Because the actual results achieved throughout the periods covered
by the Projections may vary from the projected results, the Projections should
not be relied upon as a guaranty, representation, or other assurance of the
actual results that will occur. (See Article XI.A of the Disclosure Statement,
entitled "Feasibility of the Plan and Best Interests of Creditors -- Feasibility
of the Plan.")

E.       RISKS ASSOCIATED WITH EXIT FACILITY

         The Debtors' operations are dependent on the availability and cost of
working capital financing and may be adversely affected by any shortage or
increased cost of such financing. Among the aspects of the Lender Lock-up
Agreement between the Debtors and the Lenders is the provision for the Exit
Facility. It is anticipated that the Exit Facility will provide credit
availability of up to $125 million. The Exit Facility would be secured by
guaranties and charges over the accounts receivable and inventory and, if
required, substantially all other assets of the Reorganized Debtors and its
Subsidiaries, senior to all other security including the security for the New
Senior Secured Term Debt. The Debtors anticipate that the Exit Facility would be
used to (a) fund repayment of the DIP Facility, (b) provide short-term working
capital needs, and (c) fund letters of credit within a sub-limit of the Exit
Facility. The maturity of the Exit Facility is contemplated as two years from
Plan implementation, but may be refinanced in whole but not in part by a
replacement facility with the same priority. The parties continue to negotiate
the terms of the Exit Facility, and there can be no assurances that the terms of
such a Facility will not differ materially from the terms described herein.

         The Debtors believe that substantially all of their needs for funds
necessary to consummate the Plan and for post-Effective Date working capital
financing will be met by projected operating cash flow and the Exit Facility.
The proposed Exit Facility contains certain conditions and covenants that the
Debtors may not be able to meet,

                                       73

<PAGE>   84

however. Moreover, if the Debtors require working capital greater than that
provided by the Exit Facility, they may be required either to (a) seek to
increase the availability under the Exit Facility, (b) obtain other sources of
financing or (c) curtail their operations. Some of the factors which may affect
the amount of financing required to consum mate the Plan include, without
limitation, a delay in consummating the Plan, and whether the Debtors' cash flow
prior to the Effective Date is more than budgeted. The Debtors believe that the
recapitalization to be accomplished through the Plan will facilitate the
Debtors' ability to obtain additional or replacement working capital financing.
No assurance can be given, however, that any additional replacement financing
will be available on terms that are favorable or acceptable to the Debtors.
Moreover, there can be no assurance that the Debtors will be able to obtain an
acceptable credit facility upon expiration of the Exit Facility.

F.       RISKS ASSOCIATED WITH NEW COMMON SHARES/REORGANIZED PSI COMMON SHARES;
         CHANGE IN CONTROL

         PSC's common shares traded under the symbol "PHV" in the United States
on the New York Stock Exchange (the "NYSE") until January 13, 1999, when the
common shares were temporarily halted from trading due to the company's failure
to comply with the NYSE's continued listing criteria. On April 23, 1999, the
NYSE announced that due to then recent developments in PSC's financial
condition, it would suspend the trading of PSC's common shares on the NYSE prior
to the opening on April 26, 1999, and would seek delisting of those shares. PSC
continues to pursue its remedies in regard to the listing of its common shares
on the NYSE, but there can be no assurances that PSC will be able to retain such
a listing. PSC common shares are listed and posted for trading on the Toronto
Stock Exchange and the Montreal Exchange. If the Alternate Canadian Transactions
are implemented, Reorganized PSI intends to seek to have the Reorganized PSI
Common Shares listed on the NASDAQ or AMEX exchange. There can be no assurance
that Reorganized PSI will be able to obtain such a listing.

         Pursuant to the Plan, New Common Shares or Reorganized PSI Common
Shares, as the case may be, will be issued in partial satisfaction of the Class
6 Secured Lender Claims, and if Class 7 votes to accept the Plan, the Class 7
Impaired Unsecured Claims and in full satisfaction of the Class 8 Claims and
Interests, provided, however, that if the holders of Allowed Class 7 Claims vote
to reject the Plan, no New Common Shares or Reorganized PSI Common Shares, as
the case may be, will be issued to holders of Class 7, 8A, 8B or 8C Claims. In
any case, distribution of New Common Shares or Reorganized PSI Common Shares, as
the case may be, shall be subject to dilution on or after the Effective Date (a)
to the extent necessary to give effect to the convertibility of the New Secured
PIK Debt and the New Unsecured Convertible Notes and the exercise of the
Management Options or (b) otherwise as a result of the issuance of common
shares, implementation of other management incentive programs or other action
taken by the board of directors of Reorganized PSC or Reorganized PSI, as the
case may be (the "Dilution"). The Plan contemplates certain management stock
options and the issuance of New Secured PIK Debt and, subject to the Class 7
Election, New Unsecured Convertible Notes which will be convertible into PSC
Common Shares or Reorganized PSI Common Shares, as the case may be. To the
extent such equity interests are issued after the Effective Date, the percentage
ownership of PSC Common Shares or Reorganized PSI Common Shares, as the case may
be, of the holders of Class 6, Class 7 and Class 8 Claims and Interests will be
diluted on a pro rata basis. In addition, the market price of the PSC's common
shares in the past has been and may in the future be volatile. A variety of
events, including quarter-to-quarter variations in operating results, news
announcements, trading volume, general market trends and other factors could
result in wide fluctuations in the market price of the PSC Common Shares.
Reorganized PSI has never had its stock publicly listed but it is expected that
the Reorga nized PSI Common Shares will be subject to wide fluctuations in
market price as the shares of PSC have been in the past.

         If the Canadian Reorganization Plan is implemented, and if PSC is
delisted and is unable to obtain a relisting on the NYSE in connection with its
restructuring, then it will seek to have PSC Common Shares listed on the NASDAQ
or AMEX exchanges. There can be no assurances that Reorganized PSC will be able
to obtain such a listing.

         Following the Debtors' restructuring, the Lenders, in the aggregate,
will own at least ninety-one percent (91%) of Reorganized PSC's or Reorganized
PSI's, as the case may be, outstanding common shares and will control

                                       74

<PAGE>   85

such board of directors. Accordingly, the Lenders, if acting together, would be
able to exert substantial influence over the Reorganized Debtors and to control
effectively most matters requiring shareholder approval, including all
fundamental corporate actions such as mergers, substantial acquisitions and
divestitures. The voting power of these shareholders under certain circumstances
could have the effect of causing, delaying or preventing a change of control of
the Debtors, the effect of which may be to deprive the Debtors' shareholders of
a control premium that might otherwise be realized in connection with the
acquisition of the Debtors. In addition, if the Canadian Reorganization Plan is
implemented, certain provisions of the PSC's Amended Articles of Amalgamation
and Bylaws as well as provisions in certain agreements, including the
Shareholder Rights Plan, and the Business Corporations Act (New Brunswick) may
have the effect of delaying, deferring or preventing a change of control.
Similarly, if the Alternate Canadian Transactions are implemented, then certain
provisions of Reorganized PSI's Articles of Incorporation and By-laws as well as
provisions in certain agreements, including the Shareholder Rights Plan, and the
Delaware General Business Corporation Act may have the effect of delaying,
deferring or preventing a change of control.

G.       RISKS ASSOCIATED WITH NEW SECURED PIK DEBT, NEW UNSECURED PIK NOTES
         AND NEW UNSECURED CONVERTIBLE NOTES

         There can be no assurance that the Debtors will generate sufficient
cash from operations described in the Projections, see Appendix F to the
Disclosure Statement, to repay the debt and notes being issued under the Plan at
maturity, or that the Debtors will not use cash in excess of the amounts set
forth in the Projections and, accordingly, satisfaction of the New Secured PIK
Debt, New Senior Secured Term Debt, New Unsecured PIK Notes, and New
Unsecured Convertible Notes at their respective maturity dates may be dependent
upon the ability of the Reorga nized Debtors to refinance the indebtedness
thereunder at maturity or to raise sufficient capital to make such payments.

H.       DISRUPTION OF OPERATIONS DUE TO BANKRUPTCY FILING

         As noted in Article III of the Disclosure Statement, entitled
"Treatment of Trade Creditors, Customers and Employees," as a part of the first
day relief sought in the Chapter 11 Cases the Debtors obtained orders from the
Bankruptcy Court allowing them to pay prepetition employee obligations and
certain prepetition key vendor trade claims in the ordinary course of business.
The Debtors therefore believe that the Solicitation with respect to the Plan
will not materially adversely affect the Debtors' relationships with customers,
employees, and suppliers, provided that the Debtors demonstrate (i) sufficient
liquidity to continue to operate their businesses and (ii) a likelihood of
emergence from Chapter 11 by November 30, 1999.

         The Debtors believe that relationships with their customers, suppliers
and employees will be maintained if the Chapter 11 process continues in a timely
fashion. However, if there is a protracted Chapter 11 process, and if the
Debtors' relationships with their customers, suppliers and employees are
adversely affected, the Debtors' operations could be materially affected.
Weakened operating results could adversely affect the Debtors' ability to
complete the solicitation of acceptances of the Plan or, if such solicitation is
successfully completed, to obtain confirmation of the Plan. In the event that
the Debtors fail to confirm the Plan, the risks associated with a protracted
Chapter 11 process or a liquidation must also be considered (See Article XII of
the Disclosure Statement, entitled "Alternatives to the Confirmation and
Consummation of the Plan"). The Debtors anticipate, however, that they will have
sufficient cash generated from current operations and provided under the DIP
Facility and the Exit Facility to service the obligations that they intend to
pay during the period prior to and at consummation.

I.       FINANCIAL UNCERTAINTY

         The Debtors' results of operations for the second half of 1998 were
significantly impacted by actions taken by the Debtors to retain customers,
suppliers' tightening trade terms and employee attrition. In addition, the
results of operations for the year ended December 31, 1998 were impacted by
special charges recorded by PSC amounting to $1.211 billion. These charges
reflect the effects of (i) decisions made with respect to the potential
disposition of

                                       75

<PAGE>   86

U.S. ferrous and certain Industrial Services Group operations; (ii) impairments
of fixed assets and related goodwill resulting from decisions to exit various
business locations or activities and dispose of the related assets; (iii)
assessments of the recoverability of fixed assets and the related goodwill of
business units in continuing use; (iv) charges for financing fees and debt
restructuring costs; (v) severance payments and other costs relating to ongoing
cost reduction measures and restructuring; (vi) the reduction in carrying value
of PSC's investment in Innovative Valve Technologies Inc. and (vii) a writedown
of PSC's investment in Strategic Holdings Inc.

         In December 1998, the Debtors decided to discontinue the non-ferrous
and copper operations of their Metals Services business. A sale of certain of
the aluminum operations included in the non-ferrous operations closed on January
11, 1999. In addition, the Debtors sold their Houston, Texas steel distribution
business in 1998. The Debtors continue to review the divestiture of certain
non-core businesses or investments. The proceeds which may be raised from these
divestitures is unknown. A gain or loss may be recorded on the divestitures but
the amount cannot be determined until definitive agreements are reached.

J.       ACQUISITION STRATEGY; INTEGRATION ISSUES

         From 1992 to 1997, PSC deployed an aggressive strategy of growth
through acquisitions. In 1997 alone, PSC acquired over 30 businesses. In
connection with these acquisitions, there may be liabilities that PSC failed to
discover, including liabilities arising from pollution of the environment or
non-compliance with environmental laws by prior owners, and for which PSC, as a
successor owner, may be responsible and that are not being discharged under the
Plan. Indemnities and warranties for such liabilities from sellers, if obtained,
may not fully cover the liabilities due to their limited scope, amounts, or
duration, the financial limitations of the indemnitor or warrantor, or other
reasons.

         There are significant uncertainties and risks relating to the
integration of an acquired company's operations. Whether the anticipated
benefits of an acquisition are ultimately achieved depends on a number of
factors, including the ability of the combined companies to achieve
administrative cost savings, insurance and bonding cost reductions, general
economies of scale and, generally, to capitalize on the combined asset base and
strategic position of the combined companies. The timing and manner of the
implementation of decisions made with respect to the ongoing business of the
combined companies following the acquisition will materially affect the
operations of the combined companies.

         Given the range of potential outcomes arising from such decisions and
the interrelationships among decisions to be made, it is difficult to quantify
with precision the impact of such decisions on the results of operations and
financial condition of the combined companies. In particular, reserves
established or charges recorded in connection with an acquisition or the
integration thereof may be insufficient and the Debtors may be required to
establish additional reserves or record additional charges at a later date.
There can be no assurance that any expected synergies will be realized or that
the results of the combined operations will be improved in a timely manner, if
at all. In addition, the process of integrating the acquired company's
operations into those of the Debtors could cause the interruption of, or the
loss of momentum in, the activities of either or both companies, which could
have an adverse effect on the combined operations.

K.       BUSINESS AND COMPETITION

         The metals and industrial services industries are highly competitive
and require substantial capital resources. Competition is both national and
regional in nature and the level of competition faced by the Debtors in their
various lines of business is significant. Technology is constantly changing.
There can be no assurance that the Debtors will be able to keep pace with
technological changes, that a competitor will not develop superior technology or
that a well capitalized competitor will not enter or expand in the areas in
which the Debtors compete.

                                       76

<PAGE>   87


         The Debtors' primary competitors in the metals industry are other scrap
processors in regions where its metals operations are located. The Debtors face
competition both on the purchase and sales sides of its business; however,
competition is particularly significant on the purchase side for access to
scrap. The Metals Services Group competes on the basis of price, processing
capability and service. The availability of scrap depends on a number of
factors, including the general level of economic activity in the industries
serviced by the Metals Services Group, many of which are cyclical in nature, and
market prices for scrap. Competition for access to scrap may intensify during
periods of scrap scarcity. There can be no assurance that the Debtors will
continue to have adequate access to scrap supplies at economic prices.

         The industrial services sector is also highly competitive and
fragmented. The Debtors compete with numerous local, regional and national
companies of varying sizes and financial resources. Competition for industrial
services is based primarily on hourly rates, productivity, safety, innovative
approaches and quality of service. The hazardous waste management industry
competes with the Debtors' industrial services operations by providing a price
competitive disposal alternative to a number of the Debtors' waste management
and by-products recovery services. The hazardous waste management industry
currently has substantial excess capacity caused by overbuild ing, continuing
efforts by hazardous waste generators to reduce volume and to manage their waste
on-site, and the uncertain regulatory environment regarding hazardous waste
management and remediation requirements. These factors have led to downward
pressure on pricing in a number of the markets served by the Debtors' industrial
services operations. The Debtors expect these conditions to continue for the
foreseeable future.

         Recently, weak market conditions in the metals recycling and industrial
services industries have had a negative impact on revenue in these areas. For
example, record steel imports have decreased domestic demand and prices for
scrap steel. These conditions have had an effect on the entire market. In
addition, the Debtors' Industrial Services Group tends to follow seasonal
patterns, with higher levels of activity during the period from April through
November and lower levels during the adverse weather conditions of winter and
early spring. These operations are also affected by the spending decisions of
the Debtors' customers, which in turn are influenced by general economic
conditions and other factors. As a result of all these factors, the Debtors'
financial performance can vary signifi cantly from period to period.

         The Debtors use a number of proprietary processes in their operations
and possess a number of United States patents and various foreign counterparts
of those patents. The Debtors rely primarily, however, on a combination of trade
secrets, confidentiality procedures and contractual provisions to protect their
intellectual property rights. The patents may be circumvented or invalidated and
afford only limited protection. Despite the Debtors' efforts to protect their
proprietary rights, unauthorized parties may attempt to obtain and use
information that the Debtors regard as confidential and proprietary, and there
can be no assurance that the Debtors' means of protecting their proprietary
rights will be adequate. The Debtors are not aware of any material claims that
any of their intellectual property infringes on the proprietary rights of third
parties. There can be no assurance, however, that third parties will not assert
infringement claims against the Debtors, which may be costly.

         The Debtors' growth also is dependent on the continuation of
outsourcing and vendor reduction trends within industrial enterprises. As these
enterprises focus on their core business, they are increasingly outsourcing
non-core, non-revenue generating activities in order to reduce costs. Such
activities can generally be performed on a more cost effective basis by
specialized industrial service and resource recovery companies which have
greater expertise, technology advantages and economies of scale. In addition,
industrial enterprises are evidencing a desire to reduce the number of vendors
of industrial and resource recovery services by purchasing services only from
those suppliers that can provide a "total service" solution, thereby providing
further administrative and cost reductions. If the pace of either of these
trends slows or reverses, it could have a material adverse effect on the
Debtors' financial position and results of operations.

                                       77

<PAGE>   88

L.       ENVIRONMENTAL MATTERS

         Environmental Regulations. The Debtors' operations are subject to
various comprehensive laws and regulations related to the protection of the
environment. Such laws and regulations, among other things, (i) regulate the
nature of the industrial by-products and wastes that the Debtors can accept for
processing at its treatment, storage and disposal facilities, the nature of the
treatment they can provide at such facilities and the location and expansion of
such facilities; (ii) impose liability for remediation and clean-up of
environmental contamination, both on-site and off-site, resulting from past and
present operations at the Debtors' facilities; and (iii) may require financial
assurance that funds will be available for the closure and post-closure care of
sites, including acquired facilities. In addition, because the Debtors provide
their customers with services designed to protect the environ ment by cleaning
and removing materials or substances from their customers' equipment or sites
that must be properly handled, recycled or removed for ultimate disposal, the
Debtors' operations are subject to regulations which impose liability on persons
involved in handling, processing, generating or transporting hazardous
materials. These requirements may also be imposed as conditions of operating
permits or licenses that are subject to renewal, modification or revocation.
These laws and regulations have become and are likely to continue to become
increasingly stringent. Existing laws and regulations, and new laws and
regulations, may require the Debtors to modify, supplement, replace or curtail
their operating methods, facilities or equipment at costs which may be
substantial without any corresponding increase in revenues.

         Hazardous substances are present in some of the processing, transfer,
storage, disposal and landfill facilities owned or used by the Debtors.
Remediation will be required at these sites at substantial cost. For each of
these sites, the Debtors, in conjunction with an environmental consultant, have
developed or are developing cost estimates that are periodically reviewed and
updated, and the Debtors maintain reserves for these matters based on such cost
estimates. Estimates of the Debtors' liability for remediation of a particular
site and the method and ultimate cost of remediation require a number of
assumptions and are inherently difficult. There can be no assurance that the
ultimate cost and expense of corrective action will not substantially exceed
such reserves and have a material adverse impact on the Debtors' operations or
financial condition.

         In the normal course of business, and as a result of the extensive
governmental regulation of industrial and environmental services and resource
recovery, the Debtors have been the subject of administrative and judicial
proceedings by regulators and have been subject to requirements to remediate
environmental contamination or to take corrective action. There will be
administrative or court proceedings in the future in connection with the
Debtors' present and future operations or the operations of acquired businesses.
In such proceedings in the past, the Debtors have been subject to monetary fines
and certain orders requiring the Debtors to take environmental remedial action.
In the future, the Debtors may be subject to monetary fines, penalties,
remediation, clean-up or stop orders, injunctions or orders to cease or suspend
certain of their practices. The outcome of any proceeding and associated costs
and expenses could have a material adverse impact on the operations or financial
condition of the Debtors.

         The Debtors' industrial services businesses are subject to extensive
governmental regulation, and the complexity of such regulation makes consistent
compliance with such laws and regulations extremely difficult. In addition, the
demand for certain of the Debtors' services may be adversely affected by the
amendment or repeal of federal, state, provincial, or foreign laws and
regulations or by changes in the enforcement policies of the regulatory agencies
concerning such laws and regulations.

         Public Concerns. There is a high level of public concern over
industrial by-products recovery and waste management operations, including the
siting and operation of transfer, processing, storage and disposal facilities
and the collection, processing or handling of industrial by-products and waste
materials, particularly hazardous materials. Zoning, permit and licensing
applications and proceedings and regulatory enforcement proceedings are all
matters open to public scrutiny and comment. As a result, from time to time, the
Debtors have been, and may in the future be, subject to citizen opposition and
publicity which may have a negative effect on their operations and delay or


                                       78

<PAGE>   89

limit the expansion and development of operating properties and could have a
material adverse effect on their operations or financial condition.

         Environmental Insurance Coverage. Consistent with industry trends, the
Debtors may not be able to obtain adequate amounts of environmental impairment
insurance at a reasonable premium to cover liability to third parties for
environmental damages. Accordingly, if the Debtors were to incur liability for
environmental damage either not provided for under such coverage or in excess of
such coverage, the Debtors' financial position and results of operations could
be materially and adversely affected.

         Jurisdictional Restrictions on Waste Transfers. In the past, various
states, provinces, counties and municipalities have attempted to restrict the
flow of waste across their borders, and various United States and Canadian
federal, provincial, state, county and municipal governments may seek to do the
same in the future. Any such border closing may result in the Debtors incurring
increased third-party disposal costs in connection with alternate disposal
arrangements.

         The Debtors are required under certain United States and Canadian laws
and regulations to demonstrate financial responsibility for possible bodily
injury and property damage to third parties caused by both sudden and non-sudden
occurrences. The Debtors are also required to provide financial assurance that
funds will be available when needed for closure and post-closure care at certain
of its treatment, storage and disposal facilities, the costs of which could be
substantial. Such laws and regulations allow the financial assurance
requirements to be satisfied by various means, including letters of credit,
surety bonds, trust funds, a financial (net worth) test and a guarantee by a
parent company. In the United States, a company must pay the closure costs for a
waste treatment, storage or disposal facility owned by it upon the closure of
the facility and thereafter pay post-closure care costs. There can be no
assurance that these costs will not materially exceed the amounts provided
pursuant to financial assurance requirements. In addition, if such a facility is
closed prior to its originally anticipated time, it is unlikely that sufficient
funds will have been accrued over the life of the facility to fund such costs,
and the owner of the facility could suffer a material adverse impact as a
result. Consequently, it may be difficult to close such facilities to reduce
operating costs at times when, as is currently the case in the industrial
services industry, excess treatment, storage or disposal capacity exists.

M.       LENDER LOCK-UP AGREEMENT

         The Plan is structured to implement the terms agreed to between the
Debtors and the Lenders memorialized in the Lender Lock-Up Agreement. Pursuant
to the Lender Lock-Up Agreement the holders of in excess of seventy-six percent
(76%) in the amount of Lender Claims and fifty percent (50%) in number of such
Lenders have agreed, subject to the terms of the Lender Lock-up Agreement, to
vote for the Plan and the Canadian Plan. The Debtors are currently not in
compliance with certain terms of the Lender Lock-up Agreement. For example, the
Lender Lockup Agreement required the Debtors to have received approval of the
Disclosure Statement for the Plan by September 15, 1999. As a result each Lender
is able to withdraw its support for the Plan and the Lender Lock-up Agreement
may be terminated, upon election, by Lenders holding in aggregate at least
fifty-one percent (51%) of the aggregate amount of Claims held by the Lenders
party to the Lender Lock-up Agreement. Accordingly, there can be no assurance
that the Debtors' Plan will gain the favorable vote of Class 6.

N.       UNIMPAIRED CLAIMS

         The Plan provides that the only claims against the Debtors that are
Impaired are the claims set forth in Classes 6, 7, 8 and 9. All other claims
against the Debtors are being left Unimpaired under the Plan. The Unimpaired
Claims include, but are not limited to, claims relating to environmental
liability, certain claims of employees for severance/retirement obligations,
contingent liabilities relating to indemnification obligations arising out of
the sale and acquisition of businesses or assets, certain indemnification claims
of current and former directors and officers assumed pursuant to the Plan,
certain litigation claims, certain claims arising out of services rendered and


                                       79

<PAGE>   90

goods sold and certain other contingent and unliquidated obligations. To the
extent that such claims are required to be reflected on financial statements,
the Debtors believe that their financial statements and projected financial
statements properly reflect these claims in accordance with generally accepted
accounting principles. However, the actual amount of such claims may materially
differ from those set forth in the financial statements and projections.
Moreover, many Unimpaired Claims are of an off-balance sheet nature and the
Debtors' liability as to such claims cannot be and has not been estimated.
Further, there are likely to be Unimpaired Claims that exist which the Debtors
are not aware of at this time. The Debtors are taking no action in the Chapter
11 Cases to estimate, disallow, liquidate or otherwise cap or quantify any
Unimpaired Claims. The liability of the Debtors as to the Unimpaired Claims
after their emergence from Chapter 11 will not have been reduced or otherwise
affected by the Chapter 11 Cases or the Plan. There can be no assurance that the
Debtors' financial position and results of operations after emergence from
Chapter 11 pursuant to the Plan could not be materially and adversely affected
by the Unimpaired Claims.

O.       UNSECURED CLAIMS

         The Plan divides Unsecured Claims that are not DIP Facility Claims,
Administrative Claims, Priority Tax Claims, Other Priority Claims, Other Secured
Claims, Intercompany Claims of non-Debtors, Secured Lender Claims, Securities
Claims, Other Securities Claims or Excluded Indemnification Obligations into
Class 3 General Unsecured Claims and Class 7 Impaired Unsecured Claims.

         As set forth on Exhibit B to the Plan and as further described in
Appendix H-1 through H-3 hereto, Class 7 Impaired Unsecured Claims consist of
those Unsecured Claims not otherwise classified above for which the Debtors, in
exercise of their business judgment, do not anticipate a go-forward business
relationship between the Reorganized Debtors and the affected creditors. As set
forth in more detail in Appendix H-1, these Claims include certain Unsecured
Claims arising from litigation, past employment and severance obligations, Old
Debenture Claims, rejected or expired lease and contract obligations and
Impaired Trade Claims and other trade obligations relating to discontinued
operations or severed business relationships. Excluded from Exhibit B are
Canadian Impaired Unsecured Claims. As set forth in Exhibit C to the Plan and as
further described in Appendix H-4, in order to comply with the ruling by Justice
Blair in the Canadian Bankruptcy Court, Canadian Impaired Unsecured Claims
consist of those Impaired Unsecured Claims (a) of Canadian residents against
Canadian Debtors that have not also been asserted against a United States Debtor
and (b) of United States residents against Canadian Debtors other than PSC that
have not also been asserted against a United States Debtor. In accordance with
terms proposed by the Official Committee, timely Claims filed in the wrong
jurisdiction (Canada or the United States) will be deemed to have been filed in
the correct jurisdiction without prejudice to the claimant. The remaining
Unsecured Claims are classified as Class 3 General Unsecured Claims and are
Unimpaired under the Plan.

P.       CLAIMS ESTIMATES

         There can be no assurance that the estimated Claim amounts set forth
herein for Class 7 are correct, and the actual Allowed amount of Claims in Class
7 may differ from the estimates. Estimated amounts are subject to certain risks,
uncertainties and assumptions. Should one or more of these risks or
uncertainties materialize, or should underlying assumptions prove incorrect, the
actual Allowed amount of Claims in Class 7 may vary from those estimated herein,
and the pro rata distribution of New Unsecured PIK Notes, New Common Shares and
New Unsecured Convertible Notes to holders of Impaired Unsecured Claims is
subject to such variation. In addition, the distributions to holders of Allowed
Class 7 Claims is dependent upon the aggregate amount of the Canadian Impaired
Unsecured Claims. The amount of such Claims will ultimately be determined by the
Bankruptcy Court, Canadian Bankruptcy Court or by estimation. There can be no
assurance that the estimated amount of the Canadian Impaired Unsecured Claims is
correct, and the actual amount of such claims ultimately allowed or estimated
may differ from the estimates. The estimated amounts are subject to risks,
uncertainties and assumptions, which if the risks or uncertainties materialize,
or underlying assumptions prove incorrect, the actual amount of Canadian
Impaired Unsecured Claims may vary from the estimates.

                                       80

<PAGE>   91

         Pursuant to a July 1, 1999 order of the Bankruptcy Court, August 13,
1999 was established as the deadline for filing Proofs of Claim in the Chapter
11 Cases (the "Bar Date"), Proofs of Claim were distributed to holders of
Impaired Unsecured Claims on or before July 6, 1999. As set forth in more detail
in Appendix H-1, as of September 9, 1999, $93 million of the Proofs of Claim
relating to Impaired Unsecured Claims scheduled on Exhibit B to the Plan have
been filed. Combined with the scheduled holders of Impaired Unsecured Claims
summarized in Appendix H-2 who failed to file a Proof of Claim by the Bar Date
and the holders of Impaired Unsecured Claims added to Exhibit B after July 22,
1999 (the date of the first amendment to Exhibit B) summarized in Appendix H-3,
the Debtors estimate that Class 7 presently consists of approximately $100.7
million in Impaired Unsecured Claims. In addition, as set forth in Appendix H-4,
the Debtors presently estimate that the Canadian Impaired Unsecured Claims set
forth in Exhibit C to the Plan do not exceed $54.5 million. The Debtors are in
the process of evaluating, formulating objections to and resolving the Claims
relating to Class 7, which process will continue after the Confirmation Date.

         The amount of Class 7 Claims may also be impacted significantly if
claims otherwise classified as Class 8B or 8C are subsequently determined not to
be subject to subordination under section 510(b) or 510(c) or disallowance
pursuant to 502(e)(1)(b) and are included in Class 7. Moreover, if claims such
as those alleged by Deloitte & Touche, currently asserted in the Canadian
proceedings, are asserted in the United States proceedings and the Bankruptcy
Court determines such claims are not subject to subordination or disallowance,
the distributions to holders of Class 7 Claims could be substantially reduced.
Additionally, in the event a settlement is reached with Deloitte & Touche, there
can be no assurance that any such settlement will not further dilute recoveries
to holders of Class 7 Claims by the inclusion of any such settlement amount in
Class 7; no settlement that results in a Claim in Class 7 that would participate
in the distributions to holders of Allowed Claims shall be reached without the
consent of the Creditors' Committee.

Q.       AFFILIATE STATUS

         To the extent that Persons deemed to be "underwriters" receive New
Common Shares, New Secured PIK Debt, New Unsecured PIK Notes or New Unsecured
Convertible Notes issued pursuant to the Plan, such Persons do not receive the
exemption from the securities laws under section 1145 of the Bankruptcy Code.
Whether or not any particular person would be deemed to be an "underwriter" with
respect to any security to be issued pursuant to the Plan would depend upon
various facts and circumstances applicable to that person. Accordingly, the
Debtors express no view as to whether any person would be an "underwriter" with
respect to any security to be issued pursuant to the Plan. Given the complex,
subjective nature of the question of whether a particular person may be an
underwriter, the Debtors make no representations concerning the right of any
person to trade in the New Securities to be transferred pursuant to the Plan.
The Debtors recommend that holders of Claims receiving New Securities pursuant
to the Plan consult their own counsel concerning whether they may freely trade
such securities.

         Persons that are "affiliates" of the Reorganized Debtor but are not
otherwise "underwriters" within the meaning of section 1145(b) of the Bankruptcy
Code, may be able to sell the New Common Shares, New Secured PIK Debt, New
Unsecured PIK Notes and New Unsecured Convertible Notes without registration,
pursuant to the exemption from registration provided by Rule 144 under the
Securities Act. Rule 144 permits "affiliates" of the issuer to sell, within any
three-month period, the greater of one percent (1%) of the shares or other units
of the class outstanding, or the average weekly trading volume in such
securities on all national securities exchanges or automated quotation systems,
during the four calendar weeks preceding the date on which notice of such sale
was filed pursuant to Rule 144, subject to the satisfaction of certain other
requirements of Rule 144 regarding the manner of sale, notice requirements and
the availability of current public information regarding the issuer.

R.       RELIANCE ON KEY PERSONNEL

         One of the Debtors' primary assets is their highly skilled personnel,
who have the ability to leave the Debtors and so deprive them of the skill and
knowledge essential for performance of new and existing contracts.

                                       81

<PAGE>   92

The Debtors operate a service business which is highly dependent on their
customers' belief that the Debtors will perform tasks of the highest standards
over an extended period of time. Continued deterioration of the Debtors'
business, or loss of a significant number of key personnel, will have a material
adverse effect on the Debtors and may threaten their ability to survive as going
concerns.

         The Debtors' successful transition through the restructuring process is
dependent in part on their ability to retain and motivate their officers and key
employees. The Debtors' current financial difficulties have had a detrimental
effect on their ability to attract and retain key officers and employees. There
can be no assurance that the Debtors will be able to retain or employ qualified
management and technical personnel. While the Debtors have entered into
employment agreements with certain members of their senior management, should
any of these persons be unable or unwilling to continue their employment with
the Debtors, the business prospects of the Debtors could be materially and
adversely affected.

S.       YEAR 2000 ISSUE

         The Year 2000 issue affects computer systems that have time sensitive
programs that may not properly recognize the year 2000. The Debtors are actively
engaged, but have not yet completed, reviewing, correcting and testing all of
the Year 2000 compliance issues. The failure to correct a material Year 2000
problem could result in an interruption in, or a failure of, certain normal
business activities or operations. Such failures could materially or adversely
affect the Debtors' results of operations, liquidity and financial condition.
Due to the general uncertainty inherent in the Year 2000 problem, the Debtors
are unable to determine at this time whether the consequences of the Year 2000
failures will have a material adverse affect on the results of operations,
liquidity and financial condition of the Debtors.


                                  ARTICLE VIII.

       NEW DEBT AND SECURITIES TO BE ISSUED AND TRANSFERRED UNDER THE PLAN

         The following discussion summarizes the material provisions of the New
Common Shares, New Senior Secured Term Debt, New Secured PIK Debt, New Unsecured
PIK Notes and New Unsecured Convertible Notes. This summary does not purport to
be complete and is qualified in its entirety by reference to the Articles of
Incorporation and Bylaws of the Reorganized Debtors, the form of the Amended and
Restated Term Credit Agreement, the form of New Unsecured PIK Notes Indenture,
the form of the New Unsecured Convertible Notes Indenture and the Shareholder
Rights Plan, to be appended in the Plan Supplement.

A.       NEW COMMON SHARES/PSC COMMON SHARES/REORGANIZED PSI COMMON SHARES

         1.         If the Canadian Reorganization Plan is Implemented

                    The New Common Shares will be issued to the various classes
under the Plan according to the terms described above. The effects of the
Reverse Stock Split on the New Common Shares and the resulting PSC Common Shares
are also described above. Following the continuance of Reorganized PSC in New
Brunswick, the rights of holders of the PSC Common Shares will be governed by
the laws of the Province of New Brunswick, as well as by the Reorganized Debtor
Articles of Incorporation and the Reorganized Debtor Bylaws. Under the
Reorganized Debtor Articles of Incorporation, the holders of PSC Common Shares
will be entitled to one vote for each share held of record on all matters
submitted to a vote of shareholders, including the election of directors. The
PSC Common Shares will not have cumulative voting rights. As a result, the
holders of more than fifty percent (50%) of PSC Common Shares will be able to
elect one hundred percent (100%) of the directors to be elected if they choose
to do so. In such event, the holders of the remaining PSC Common Shares will not
be able to elect any directors. Holders of PSC Common Shares will be entitled to
participate equally in such dividends as may be

                                       82

<PAGE>   93

declared by the board of directors out of funds legally available therefor.
However, it is not anticipated that dividends will be paid on the PSC Common
Shares in the foreseeable future. In the event of a liquidation, dissolution or
winding up of the Reorganized Debtor, holders of PSC Common Shares will be
entitled to participate equally in all assets remaining after payment of
liabilities and the liquidation preference of any preferred shares of the
Reorganized Debtor. Holders of PSC Common Shares will have no preemptive rights.
Holders of PSC Common Shares will have no rights to convert their PSC Common
Shares into any other securities and will have no redemption provisions or
sinking fund provisions with respect to such shares. The registrar and transfer
agent for the PSC Common Shares will be selected prior to the Effective Date.

         2.         If the Alternate Canadian Transactions are Implemented

                    In the event the Alternate Canadian Transactions are
implemented, Reorganized PSI will issue up to 24,000,000 shares of Reorganized
PSI Common Shares pro rata to the various classes according to the terms set
forth in Article II.C.1 and II.E above. The rights of the holders of Reorganized
PSI Common Shares will be governed by the laws of the State of Delaware as well
as the Reorganized Debtor Certificate of Incorporation and Reorganized Debtor
Bylaws. Under the Reorganized Debtor Certificate of Incorporation, the holders
of PSI Common Shares will be entitled to one vote for each share held of record
on all matters submitted to a vote of shareholders, including the election of
Directors. The Reorganized PSI Common Shares will not have cumulative voting
rights. As a result, the holders of more than fifty percent (50%) of Reorganized
PSI Common Shares will be able to elect one hundred percent (100%) of the
Directors to be elected if they choose to do so. In such event, the remaining
Reorganized PSI Shareholders will not be able to elect any directors. Holders of
Reorganized PSI Common Shares will be entitled to participate equally in such
dividends as may be declared by the Board of Directors out of funds legally
available therefor. However, it is not anticipated that dividends will be paid
on the Reorganized PSI Common Shares in the foreseeable future. In the event of
a dissolution or winding up of Reorganized PSI, holders of Reorganized PSI
Common Shares will be entitled to participate equally in all assets remaining
after payment of liabilities and the liquidation preference of any preferred
shares of Reorganized PSI. Holders of Reorganized PSI Common Shares will have no
rights to convert their Reorganized PSI Common Shares into any other securities
and will have no redemption provisions or sinking fund provisions with respect
to such shares. The registrar and transfer agent for the Reorganized PSI Common
Shares will be selected prior to the Effective Date.

B.       NEW SENIOR SECURED TERM DEBT

         The New Senior Secured Term Debt of Reorganized PSI will be governed by
the terms of the Amended and Restated Term Credit Agreement and will be in the
aggregate principal amount of $250 million minus an amount equal to the Net
Asset Sale Proceeds Pool (the amount the Lenders receive from the proceeds in
partial satisfaction of their Secured Lender Claims). Reorganized PSI shall have
the right to prepay the New Senior Secured Debt subject to a prepayment premium.
Interest on the New Senior Secured Term Debt will be nine percent (9%) per annum
payable quarterly in arrears on the first business day of each financial
quarter, provided that during the first 12 months subsequent to the Effective
Date of the Plan, Reorganized PSI shall pay interest on the New Senior Secured
Term Debt to the extent of the lesser of nine percent (9%) per annum and
$20,000,000, and accrue the balance thereof subject to the mandatory prepayment
obligations in effect for the New Senior Secured Term Debt. In addition, the New
Senior Secured Term Debt, as well as the New Secured PIK Debt, will be secured
by guaranties and charges over substantially all of the assets of the
Reorganized Debtors, ranking in priority to all claims other than the Exit
Facility, and existing Liens, ranking in priority to the Liens of the Lenders
under the Pre-Petition Credit Agreement, as may be applicable to particular
assets. The New Senior Secured Term Debt will mature five (5) years from the
Effective Date of the Plan and shall be governed by the terms of the Amended and
Restated Term Credit Agreement.

         The covenants for the New Senior Secured Term Debt will be
substantially similar to those in the Pre-Petition Credit Agreement and the
financial covenants shall be set forth in the Plan Supplement.

                                       83

<PAGE>   94


C.       NEW SECURED PIK DEBT

         The New Secured PIK Debt will be issued to holders of Class 6 Secured
Lender Claims. The New Secured PIK Debt will be issued by Reorganized PSC (if
the Canadian Reorganization Plan is sanctioned) or Reorganized PSI (if the
Alternate Canadian Transactions are implemented or the Canadian Plan Condition
is waived) under the Amended and Restated Term Credit Agreement between
Reorganized PSC (if the Canadian Reorganization Plan is sanctioned) and
Reorganized PSI (if the Canadian Reorganization Plan is sanctioned) and holders
of Secured Lender Claims.

         The New Secured PIK Debt will mature five years after the Effective
Date. The New Secured PIK Debt will have a rate of interest of ten percent (10%)
per annum. Subject to the terms of mandatory prepayments described in the second
succeeding sentence, interest will compound quarterly in arrears and will be
payable at maturity. The mandatory prepayments require that proceeds from an
annual cash sweep for the first two years and a cumulative quarterly cash sweep
thereafter will be applied in the following manner: (i) first, to pay any
interest accrued during the first twelve months subsequent to the Effective Date
with respect to New Senior Secured Term Debt, together with accrued interest on
any such deferred interest at the rate of nine percent (9%) per annum; (ii)
second, to pay accrued but unpaid interest with respect to the New Secured PIK
Debt and (iii) third, to repay New Senior Secured Term Debt. Such mandatory
prepayments from "Cash Flow Available for Debt Service" or "Net Asset Sale
Proceeds" (each as defined in the Restructuring Term Sheet) shall not cause the
incurrence of additional prepayment penalties or fees.

         The New Secured PIK Debt will be convertible until maturity at the
option of the holders into twenty-five percent (25%) of the PSC Common Shares
(if the Canadian Reorganization Plan is sanctioned) or the Reorganized PSI
Common Shares (if the Alternate Canadian Transactions are implemented or the
Canadian Plan Condition is waived), in the aggregate, on a fully-diluted basis
as of the Effective Date. The New Secured PIK Debt will contain anti-Dilution
provisions applicable in a public offering of convertible debt, including giving
effect to the issuance of any PSC Common Shares or Reorganized PSI Common
Shares, as the case may be, under the Shareholder Rights Plan. Interest on New
Secured PIK Debt will not be convertible.

         The New Secured PIK Debt will be redeemable in the following
circumstances: If (a) an offer is made to holders of PSC Common Shares or
Reorganized PSI Common Shares, as the case may be, to acquire all of the shares,
or, in the case of an offer by an existing beneficial owner or owners of such
shares, to acquire all of such shares not already owned by such owner(s)
together with persons acting in concert (the shares already owned being the
"Offeror's Existing Holdings"), (b) under the offer the Offeror acquires (1) PSC
Common Shares or Reorga nized PSI Common Shares, as the case may be, which
together with the Offeror's Existing Holdings amount to sixty-seven percent
(67%) or more of the PSC Common Shares or Reorganized PSI Common Shares, as the
case may be, or (2) a majority of the PSC Common Shares or Reorganized PSI
Common Shares, as the case may be, other than the Offeror's Existing Holdings,
whichever is greater, and (c) the person or persons making the offer (the
"Offeror") notifies the Reorganized Debtors that it requires the Reorganized
Debtors to exercise such redemption right, then, subject to the following
sentence, the Reorganized Debtors will have the right to redeem the New Secured
PIK Debt for a price (the "Redemption Price") equal to 115% of the face amount
of such notes plus all accrued interest on the New Secured PIK Debt. If the
Offeror has notified the Reorganized Debtors that it requires the Reorganized
Debtors to exercise the redemption right and the amount the holders of the New
Secured PIK Debt would have received by converting the convertible New Secured
PIK Debt to PSC Common Shares or Reorganized PSI Common Shares, as the case may
be, and tendering them to the Offeror under its offer (the "Tender Price") would
be greater than the Redemption Price of such Notes, any New Secured PIK Note
which has not been converted by the close of business on the day prior to the
redemption dates set out in the redemption notice issued by the Reorganized
Debtors will be deemed to have been converted and tendered to the Offeror's
offer, and the holders of the convertible New Secured PIK Debt will be entitled
to receive the Tender Price.

                                       84

<PAGE>   95

         The New Secured PIK Debt may not be redeemed prior to the end of the
first full year after the Effective Date except as provided above. Commencing in
the second year after the Effective Date, PSC may redeem the New Secured PIK
Debt upon payment of the following percentage of the face amount of the New
Secured PIK Debt during the periods following the Effective Date indicated
below, plus all accrued interest on the New Secured PIK Debt:


<TABLE>
<S>             <C>
Year 1          Not redeemable
Year 2          125%
Year 3          125%
Year 4          116 2/3 %
Year 5          108 1/3%
Maturity        100%
</TABLE>

         The New Secured PIK Debt will be secured by guaranties and charges over
substantially all of the assets of the Reorganized Debtors and their affiliates
and will rank pari passu with the New Senior Secured Term Debt, ranking in
priority to all claims other than the exit/working capital financing, and
existing senior liens ranking in priority to the Liens of the Lenders under the
Pre-Petition Credit Agreement, as may be applicable to particular assets.

         Covenants

         The covenants of the New Secured PIK Debt will be stated in the Amended
and Restated Credit Agreement. So long as the Amended and Restated Credit
Agreement is in effect, there are restrictions on the creation, incurrence or
existence of debt; the creation, incurrence or existence of liens; the
disposition of property; transactions with affiliates; acquisitions; capital
expenditures; and the treatment of the New Unsecured PIK Notes. Additionally,
the financial covenants governing the New Senior Secured Term Debt and described
above also apply to the New Secured PIK Debt.

D.       NEW UNSECURED PIK NOTES

         The New Unsecured PIK Notes will be issued by Reorganized PSC (if the
Canadian Reorganization Plan is sanctioned) or Reorganized PSI (if the Alternate
Canadian Transactions are implemented or the Canadian Plan Condition is waived)
to holders of Allowed Class 7 Claims, holders of Canadian Impaired Unsecured
Claims, and, if Class 7 votes to reject the Plan, to holders of Allowed Class 6
Claims, provided, however, that if Class 7 votes to reject the Plan and the
Alternate Canadian Transactions are implemented, no New Unsecured PIK Notes will
be issued. If the Canadian Reorganization Plan is sanctioned, then the amount of
the New Unsecured PIK Notes to be distributed under the U.S. Plan will be
between $48 million and $60 million, depending upon the Class 7 Election, minus
the amount of the New Unsecured PIK Notes to be allocated under the Canadian
Reorganization Plan. If the Alternate Canadian Transactions are implemented,
then the amount of New Unsecured PIK Notes to be distributed under the U.S. Plan
will be between $48 million and $60 million, depending upon the Class 7
Election. The New Unsecured PIK Notes will be issued under the New Unsecured PIK
Notes Indenture between Reorganized PSC or Reorganized PSI, as the case may be,
and a trustee to be selected by the Reorganized Debtors. The New Unsecured PIK
Notes Indenture shall be substantially in the form included in the Plan
Supplement. The New Unsecured PIK Notes Indenture shall meet the requirements of
the Trust Indenture Act of 1939, as amended.

         The New Unsecured PIK Notes will mature ten (10) years from the
Effective Date. The New Unsecured PIK Notes will have a rate of interest at six
percent (6%) per annum. Interest will accrue and be paid in arrears by the
issuance of additional New Unsecured PIK Notes, provided that, if the New
Secured PIK Debt is not in default,

                                       85

<PAGE>   96

cash interest will be payable semi-annually on the New Unsecured PIK Notes
following repayment in full of the New Secured PIK Debt. All interest shall be
based on a 360-day year and actual days elapsed. Commencing five (5) years from
the Effective Date, provided the New Senior Secured Term Debt is not in default,
the New Unsecured PIK Notes will be amortized in equal installments at the end
of years six (6) to ten (10). The New Unsecured PIK Notes will be unsecured
obligations of Reorganized PSC or Reorganized PSI, as the case may be, and shall
be pari passu with the New Unsecured Convertible Notes. The New Unsecured PIK
Notes will be fully subordinated to all debt governed by a bank credit facility
(including the Exit Facility and the New Senior Debt) and any extensions,
renewals or refinancings of any such debt. The New Unsecured PIK Notes will be
redeemable at the option of the Reorganized Debtors, at any time at the
principal amount outstanding plus accrued interest. Upon a change of control in
the Reorganized Debtors (as will be defined in the Indenture) each holder of the
New Unsecured PIK Notes will be entitled to put that holder's New Unsecured PIK
Note to the Reorganized Debtors at a discount rate of sixteen percent (16%).

         In the event the New Unsecured PIK Notes are not paid when due, the
holders thereof will be entitled to exercise their rights and remedies pursuant
to the New Unsecured PIK Notes Indenture and applicable law.

E.       NEW UNSECURED CONVERTIBLE NOTES

         The New Unsecured Convertible Notes will be issued by Reorganized PSC
(if the Canadian Reorganiza tion Plan is sanctioned) or Reorganized PSI (if the
Alternate Canadian Transactions are implemented or the Canadian Plan Condition
is waived) in an aggregate face amount not to exceed $18 million. The terms of
the New Unsecured Convertible Notes will be governed by the New Unsecured
Convertible Notes Indenture. The New Unsecured Convertible Notes Indenture shall
meet the requirements of the Trust Indenture Act of 1939 as amended. The New
Unsecured Convertible Notes will be unsecured obligations of Reorganized PSC or
Reorganized PSI, as the case may be, and shall be pari passu with the New
Unsecured PIK Notes.

         The New Unsecured Convertible Notes shall have an interest rate of
three percent (3%) per annum, payable semi-annually, commencing on the third
anniversary of the Effective Date, mature on the 20th anniversary of the
Effective Date and are convertible into PSC Common Shares (if the Canadian
Reorganization Plan is sanctioned) or Reorganized PSI Common Shares (if the
Alternate Canadian Transactions are implemented or the Canadian Plan Condition
is waived) at a price of $30 per share (every $30 of face amount of New
Unsecured Convertible Notes is convertible into one share of PSC Common Shares
or Reorganized PSI Common Shares, as the case may be).

         The Reorganized Debtors will use their reasonable best efforts to list
the New Unsecured Convertible Notes on the same stock exchange market as the PSC
Common Shares or Reorganized PSI Common Shares, as the case may be, are listed.
The holders of the New Unsecured Convertible Notes shall have the right upon a
"Change of Control" to choose to put the New Unsecured Convertible Notes to
Reorganized PSC or Reorganized PSI, as the case may be, in exchange for the
amounts specified in the schedule below or to accept new convertible notes
issued by the acquiring entity with terms economically comparable to the New
Unsecured Convertible Notes prior to the Change of Control. "Change of Control"
shall mean an acquisition by a person or persons acting in concert of ownership
of more than fifty percent (50%) of the common shares of Reorganized PSC or
Reorganized PSI, as the case may be, excluding changes in ownership resulting
from transactions by parties owning greater than ten percent (10%) of the common
shares of Reorganized PSC or Reorganized PSI, as the case may be, as of the
Effective Date. Upon a change of control through an acquisition by a person or
persons acting in concert of ownership of more than fifty percent (50%) of the
common shares of Reorganized PSC or Reorganized PSI, as the case may be, with no
exclusion for parties owning greater than ten percent (10%) of the common shares
of Reorganized Debtors on the Effective Date of the Plan, the Reorganized
Debtors may redeem the New Unsecured Convertible notes at the principal amount
outstanding plus accrued and unpaid interest.

                                       86

<PAGE>   97

         If Class 7 votes to reject the Plan, no New Unsecured Convertible Notes
will be issued. Moreover, if no Qualifying Class 7 Creditors choose New
Unsecured Convertible Notes in the Class 7 Election, no New Unsecured
Convertible Notes will be issued.

         The following is a schedule of the amounts at which the holders of the
convertible notes will be entitled to demand redemption upon a change of
control:

                                   ARTICLE IX.

               APPLICABILITY OF FEDERAL AND OTHER SECURITIES LAWS

         No registration statement will be filed under the Securities Act or any
state securities laws with respect to the offer of the New Common Shares1, the
New Secured PIK Debt, the New Unsecured PIK Notes or the New Unsecured
Convertible Notes pursuant to this solicitation, issuance or subsequent transfer
of such securities under the Plan. The Debtors believe that, subject to certain
exceptions described below, various provisions of the Securities Act, the
Bankruptcy Code and state securities laws exempt from federal and state
securities registration requirements (i) the offer and the sale of such
securities pursuant to the Plan; and (ii) subsequent transfers of such
securities.

A.       OFFER AND SALE OF NEW COMMON SHARES, NEW SECURED PIK DEBT, NEW
         UNSECURED PIK NOTES AND NEW UNSECURED CONVERTIBLE NOTES PURSUANT TO
         THE PLAN:  BANKRUPTCY CODE EXEMPTION FROM REGISTRATION REQUIREMENTS

         Section 1145(a)(1) of the Bankruptcy Code exempts the offer and sale of
securities under a plan of reorganization from registration under both the
Securities Act and state securities laws, if three principal requirements are
satisfied: (i) the securities must be issued "under a plan" of reorganization by
the debtor or its successor under a plan or by an affiliate participating in a
joint plan of reorganization with the debtor; (ii) the recipients of the
securities must hold a pre-petition or administrative expense claim against the
debtor or an interest in the debtor; and (iii) the securities must be issued
entirely in exchange for the recipient's claim against or interest in the
debtor, or "principally" in such exchange and "partly" for cash or property. The
Debtors believe that the offer and sale of the

         applicable to "PSC Common Shares" and "Reorganized PSI Common Shares."

New Common Shares, New Secured PIK Debt, New Unsecured PIK Notes and New
Unsecured Convertible Notes under the Plan satisfies the requirements of section
1145(a)(1) of the Bankruptcy Code and is, therefore, exempt from registration
under the Securities Act and state securities laws.

B.       SUBSEQUENT TRANSFERS OF NEW COMMON SHARES, NEW SECURED PIK DEBT, NEW
         UNSECURED PIK NOTES AND NEW UNSECURED CONVERTIBLE NOTES

         1.         Federal Securities Laws: Section 1145(c) of the Bankruptcy
                    Code

                    Section 1145(c) of the Bankruptcy Code deems any offer or
sale of securities of the kind and in the manner specified in section 1145(a)(1)
of the Bankruptcy Code to have been a public offering. Accordingly, the New
Common Shares, New Secured PIK Debt, New Unsecured PIK Notes and New Unsecured
Convertible Notes generally will be freely transferable by holders of Impaired
Claims and Interests under the Securities Act unless the Holder is deemed, by
section 1145(b) of the Bankruptcy Code, to be an "underwriter" for purposes of
section 2(11) of the Securities Act with respect to such securities. Section
1145(b) of the Bankruptcy Code deems any entity to be an "underwriter" under
section 2(11) of the Securities Act, if such entity:

                    (a)    purchases a claim against, interest in, or claim for
                           an administrative expense in the case concerning, the
                           debtor, if such purchase is with a view to
                           distributing any security received in exchange for
                           such a claim or interest;

                    (b)    offers to sell securities offered or sold under a
                           plan the holders of such securities;

                    (c)    offers to buy securities offered or sold under the
                           plan from the holders of such securities, if the
                           offer to buy is: (A) with view to distribution of
                           such securities; and (B) under an agreement made in
                           connection with the plan, with the consummation of
                           the plan, or with the offer or sale of securities
                           under the plan; or

                    (d)    is an "issuer" with respect to the securities, as the
                           term "issuer" is defined in section 2(11) of the
                           Securities Act.

                    Under section 2(11) of the Securities Act, an "issuer"
includes any person directly or indirectly controlling or controlled by the
issuer, or any person under direct or indirect common control with the issuer.

                    To the extent that holders of Impaired Claims or Interests
who receive New Common Shares, New Secured PIK Debt, New Unsecured PIK Notes,
New Unsecured Convertible Notes or other securities pursuant to the Plan are
deemed to be "underwriters," such securities may not be resold by such persons
unless such securities are registered under the Securities Act or an exemption
from such registration requirements is available. However, it is anticipated
that holders of a portion of the New Common Shares will be entitled to demand
that the Reorga nized Debtor register the resale of such shares under the
Securities Act and that such holders of New Common Shares will be permitted to
obtain registration of the sale of their New Common Shares in certain
circumstances in connection with certain registered offerings of New Common
Shares by Reorganized PSC. (See Article IX.C hereof - "Registration Rights
Agreement").

                    Whether or not any particular person would be deemed to be
an "underwriter" with respect to the New Common Shares, New Secured PIK Debt,
New Unsecured PIK Notes, New Unsecured Convertible Notes or other security to be
issued pursuant to the Plan would depend upon various facts and circumstances
applicable to that person. Accordingly, the Debtors express no view as to
whether any particular person receiving New Common Shares, New Secured PIK Debt,
New Unsecured PIK Notes, and/or New Unsecured Convertible Notes under the Plan
would be an "underwriter" with respect to the New Common Shares, New Secured PIK
Debt, New Unsecured PIK Notes, and/or New Unsecured Convertible Notes.

                                       88

<PAGE>   99

                    GIVEN THE COMPLEX AND SUBJECTIVE NATURE OF THE QUESTION OF
WHETHER A PARTICULAR HOLDER MAY BE AN UNDERWRITER, THE DEBTORS MAKE NO
REPRESENTATION CONCERNING THE RIGHT OF ANY PERSON TO TRADE IN THE NEW COMMON
SHARES, NEW SECURED PIK DEBT, NEW UNSECURED PIK NOTES AND NEW UNSECURED CON
VERTIBLE NOTES. THE DEBTORS RECOMMEND THAT POTENTIAL RECIPIENTS OF THE NEW
COMMON SHARES, NEW SECURED PIK DEBT, NEW UNSECURED PIK NOTES AND NEW UNSECURED
CONVERTIBLE NOTES CONSULT THEIR OWN COUNSEL CONCERNING WHETHER THEY MAY FREELY
TRADE NEW COMMON SHARES, NEW SECURED PIK DEBT, NEW UNSECURED PIK NOTES, AND NEW
UNSECURED CONVERTIBLE NOTES WITHOUT COMPLIANCE WITH THE SECURITIES ACT OR THE
EXCHANGE ACT.

                    Persons that are "affiliates" of the Reorganized Debtors but
are not otherwise "underwriters" within the meaning of section 1145(b) of the
Bankruptcy Code, may be able to sell the New Common Shares, New Secured PIK
Debt, New Unsecured PIK Notes and New Unsecured Convertible Notes without
registration, pursuant to the exemption from registration provided by Rule 144
under the Securities Act. Rule 144 permits "affiliates" of the issuer to
publicly sell, within any three-month period, the greater of one percent (1%) of
the shares or other units of the class outstanding, or the average weekly
trading volume in such securities on all national securities exchanges or
automated quotation systems, during the four calendar weeks preceding the date
on which notice of such sale was filed pursuant to Rule 144, subject to the
satisfaction of certain other requirements of Rule 144 regarding the manner of
sale, notice requirements and the availability of current public information
regarding the issuer.

         2.         Subsequent Transfers of New Common Shares, New Secured PIK
                    Debt, New Unsecured PIK Notes and New Unsecured Convertible
                    Notes Under State Securities Laws

                    If the New Common Shares are listed on the New York Stock
Exchange, the American Stock Exchange or the Nasdaq National Market, the New
Common Shares, New Secured PIK Debt, New Unsecured PIK Notes, and New Unsecured
Convertible Notes will be generally freely tradeable under state securities
laws. If the New Common Shares are not listed on any of the above exchanges or
the Nasdaq National Market, the New Common Shares, New Secured PIK Debt, New
Unsecured PIK Notes and New Unsecured Convertible Notes will not be freely
tradeable under state securities laws unless there is an available exemption
from registration under such laws. A majority of states provide an exemption
from registration for secondary market transactions under the so-called "manual
exemption" if financial and other information about an issuer is published in
certain manuals published by Moody's Investor Service, Inc. or Standard &
Poor's. If the New Common Shares are not listed on one of the above exchanges or
the Nasdaq National Market, the Reorganized Debtors intend to provide the
necessary information in order to be able to take advantage of such manual
exemptions.

C.       REGISTRATION RIGHTS AGREEMENT

         On or before the Effective Date, Reorganized PSC (if the Canadian
Reorganization Plan is sanctioned) or Reorganized PSI (if the Alternate Canadian
Transactions are implemented or the Canadian Plan Condition is waived) will
enter into a "Registration Rights Agreement" with certain holders of Allowed
Lender Claims (the "Relevant Holders") with respect to rights of registration as
to the New Common Shares or the Reorganized PSI Common Shares, as the case may
be. The execution and delivery of such agreement is a condition precedent to the
Effective Date.

         Under the Registration Rights Agreement, each Relevant Holder will have
the right to require on one occasion the relevant Reorganized Debtor to file a
registration statement in the United States and/or a prospectus with the
applicable Canadian securities authorities with respect to an offering of such
Relevant Holder's shares of New Common Stock or the Reorganized PSI Common
Shares, as the case may be. Such right is subject to a number of exceptions and
limitations, including with regard to the number of shares to be registered and
with regard to the aggregate number of registration statements the relevant
Reorganized Debtor must file. In addition, Relevant

                                       89

<PAGE>   100

Holders will have the right to participate, subject to certain limitations, in
registrations of offerings of New Common Stock or the Reorganized PSI Common
Shares, as the case may be, demanded by other Relevant Holders or in certain
public or private sales by Reorganized PSC or Reorganized PSI, as the case may
be, of its common stock. The Registration Rights Agreement will contain
customary representations and warranties of Reorganized PSC or Reorganized PSI,
as the case may be, and the Relevant Holders, and will also provide for mutual
indemnification of the parties.

D.       CANADIAN SECURITIES LAWS

         If the Canadian Reorganization Plan is sanctioned, the issuance by PSC
of the New Common Shares, New Secured PIK Debt, New Unsecured PIK Notes and New
Unsecured Convertible Notes will be subject to the Securities Act (Ontario) and
to the applicable securities laws of such other provinces of Canada in which
persons entitled to receive such securities reside. The issuance and subsequent
transfer of such securities will be made pursuant to an exemption from
applicable dealer registration and prospectus requirements of applicable
Canadian securities laws or pursuant to discretionary orders and/or rulings from
applicable Canadian provincial securities regulatory authorities. Based on
relief granted in connection with similar CCAA restructurings in the past to
other public companies, PSC believes that such discretionary relief is
obtainable.

         If at the time of any subsequent transfer in Canada of New Common
Shares, New Secured PIK Debt, New Unsecured PIK Debt or New Unsecured
Convertible Notes, the seller holds a sufficient number of any securities of PSC
to affect materially its control, a prospectus will be required to be delivered
to the purchaser(s). For these purposes, the holding by any person or
combination of persons of more than twenty percent (20%) of the voting
securities of a company is deemed to affect materially the control of the
company. The Shareholder Rights Plan contains additional provisions which would
apply in the case of such a transfer.

         If the Alternate Canadian Transactions are implemented, the issuance by
Reorganized PSI of the Reorganized PSI Common Shares, New Secured PIK Debt, New
Unsecured PIK Notes and New Unsecured Convertible Notes will be subject to the
applicable securities law of the provinces of Canada in which persons entitled
to receive such securities reside. The issuance of such securities will be made
pursuant to an exemption from dealer registration and prospectus requirements of
applicable Canadian provincial securities laws or pursuant to discretionary
orders and/or rulings from applicable Canadian provincial securities regulatory
authorities. Reorganized PSI will apply, as necessary, to applicable Canadian
securities regulatory authorities for discretionary orders and/or rulings to
exempt the subsequent transfer of securities issued by Reorganized PSI pursuant
to the Plan from dealer registration and prospectus requirements.


                                   ARTICLE X.

                       INCOME TAX CONSEQUENCES OF THE PLAN

                    THE DISCUSSION BELOW, WHICH WAS PREPARED BY THE DEBTORS
AFTER CONSULTATION WITH THEIR U.S. COUNSEL, SKADDEN, ARPS, SLATE, MEAGHER & FLOM
LLP, IS A GENERAL SUMMARY OF CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE
CANA DIAN REORGANIZATION PLAN TO THE DEBTORS AND THEIR CREDITORS HOLDING ALLOWED
CLASS 6 CLAIMS AND ALLOWED CLASS 7 CLAIMS WHO ARE SUBJECT TO U.S. FEDERAL INCOME
TAXATION ON A NET BASIS.

                    DUE TO THE UNSETTLED AND COMPLEX NATURE OF SOME OF THE TAX
ISSUES, AS WELL AS THE POSSIBILITY THAT DEVELOPMENTS SUBSEQUENT TO THE DATE
HEREOF COULD AFFECT THE TAX CONSEQUENCES OF THE CANADIAN REORGANIZATION PLAN,
THE FOLLOWING DISCUSSION SHOULD NOT BE REGARDED AS DEFINITIVE OR AS COVERING ALL
POSSIBLE TAX


                                       90

<PAGE>   101



CONSEQUENCES. ADDITIONALLY, THIS SUMMARY DOES NOT DISCUSS ALL ASPECTS OF U.S.
FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO A PARTICULAR CREDITOR IN LIGHT
OF ITS SPECIFIC INVESTMENT CIRCUMSTANCES OR TO CERTAIN CREDITORS SUBJECT TO
SPECIAL TREATMENT UNDER THE U.S. FEDERAL INCOME TAX LAWS (INCLUDING BUT NOT
LIMITED TO, FOREIGN CORPORATIONS AND INDIVIDUALS WHO ARE NOT CITIZENS OR
RESIDENTS OF THE UNITED STATES, FINANCIAL INSTITUTIONS, BANKS, LIFE INSURANCE
COMPANIES, AND TAX-EXEMPT ORGANIZATIONS) AND DOES NOT DISCUSS ANY ASPECT OF
STATE, LOCAL OR FOREIGN TAXATION. FURTHER, THE DISCUSSION WITH RESPECT TO
CREDITORS OF THE DEBTORS IS LIMITED TO PERSONS WHO HOLD DEBT CLAIMS OF THE
DEBTORS AS "CAPITAL ASSETS" AND WHO WILL HOLD THE NEW SENIOR SECURED TERM DEBT,
NEW SECURED PIK DEBT, NEW UNSECURED PIK NOTES, NEW UNSECURED CONVERTIBLE NOTES
AND NEW COMMON SHARES AS "CAPITAL ASSETS" (GENERALLY, PROPERTY HELD FOR
INVESTMENT) WITHIN THE MEANING OF SECTION 1221 OF THE U.S. INTERNAL REVENUE CODE
OF 1986, AS AMENDED (THE "TAX CODE"). FOR THE FOREGOING REASONS, HOLDERS OF
CLAIMS ARE URGED TO CONSULT WITH THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX
CONSEQUENCES (FOREIGN, FEDERAL, STATE AND LOCAL) TO THEM OF THE CANADIAN
REORGANIZATION PLAN. IN PARTICULAR, HOLDERS ARE URGED TO CONSULT WITH THEIR TAX
ADVISORS REGARDING ANY CANADIAN INCOME AND WITHHOLDING TAX CONSEQUENCES TO THEM
RESULTING FROM THE CANADIAN REORGANIZA TION PLAN, THE EXCHANGE CONTEMPLATED BY
THE CANADIAN REORGANIZATION PLAN, AND HOLDING ANY OF THE INSTRUMENTS
CONTEMPLATED BY THE CANADIAN REORGANIZATION PLAN. THE DEBTORS ARE NOT MAKING ANY
REPRESENTATIONS REGARDING THE PARTICULAR TAX CONSEQUENCES OF THE CONFIRMATION
AND CONSUMMATION OF THE CANADIAN REORGANIZATION PLAN AS TO ANY HOLDER OF CLAIMS,
NOR ARE THE DEBTORS RENDERING ANY FORM OF LEGAL OPINION AS TO SUCH TAX
CONSEQUENCES.

                    THIS SUMMARY IS BASED UPON THE LAWS, REGULATIONS, RULINGS
AND DECISIONS IN EFFECT ON THE DATE HEREOF AND UPON PROPOSED REGULATIONS, ALL OF
WHICH ARE SUBJECT TO CHANGE (POSSIBLY WITH RETROACTIVE EFFECT) BY LEGISLATION,
ADMINISTRATIVE ACTION OR JUDICIAL DECISION. MOREOVER, DUE TO A LACK OF
DEFINITIVE JUDICIAL OR ADMINISTRATIVE AUTHORITY AND INTERPRETATION, SUBSTANTIAL
UNCERTAIN TIES EXIST WITH RESPECT TO VARIOUS TAX CONSEQUENCES OF THE CANADIAN
REORGANIZA TION PLAN AS DISCUSSED HEREIN. NO RULINGS HAVE BEEN OR ARE EXPECTED
TO BE RE QUESTED FROM THE U.S. INTERNAL REVENUE SERVICE (THE "SERVICE")
CONCERNING ANY OF THE TAX MATTERS DESCRIBED HEREIN AND THERE CAN BE NO ASSURANCE
THAT THE SERVICE WILL NOT CHALLENGE THE POSITIONS TAKEN BY THE DEBTORS OR THEIR
AFFILIATES WITH RESPECT TO ANY OF THE ISSUES ADDRESSED HEREIN OR THAT A COURT
WOULD NOT SUSTAIN SUCH A CHALLENGE.

                    THIS SUMMARY DOES NOT REVIEW THE U.S. FEDERAL INCOME TAX
CONSEQUENCES OF, OR ANY OTHER CONSIDERATIONS RELATING TO, THE ALTERNATE CANADIAN
TRANSACTIONS. AS THESE MAY BE DIFFERENT IN MATERIAL RESPECTS FROM THOSE OF THE
CANADIAN REORGANIZATION PLAN WHICH ARE DESCRIBED BELOW, CREDITORS ARE URGED AND
EXPECTED TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE ALTERNATE
CANADIAN TRANSACTIONS.

A.       FEDERAL INCOME TAX CONSEQUENCES TO THE DEBTORS


                                       91
<PAGE>   102
         1.         Discharge of Indebtedness

                    Under the Tax Code, a U.S. taxpayer generally must include
in gross income the amount of any discharged indebtedness realized during the
taxable year, except to the extent payment of such indebtedness would have
resulted in a tax deduction. Section 108 of the Tax Code provides, however, that
when the discharge of indebtedness occurs in a case under the Bankruptcy Code,
gross income does not include any amount that otherwise would be included in
gross income by reason of the discharge of indebtedness. Instead, the discharged
indebtedness in a bankruptcy case will generally be applied to reduce certain
tax attributes of the taxpayer, including net operating losses ("NOLs"),
investment tax credit carryforwards ("ITCs") and tax basis in property. (NOLs,
ITCs and tax basis in property of PSI, the common parent of the Debtors' U.S.
consolidated group for U.S. federal income tax purposes, and of Allwaste and
other U.S. Debtors liable on Claims (the "U.S. Debtors") are referred to
collectively as "Tax Attributes".)

                    Satisfaction of Allowed Class 6 Claims, Allowed Class 7
Claims and cancellation of other indebtedness pursuant to the Canadian
Reorganization Plan will result in a discharge of indebtedness and a
corresponding reduction in the respective U.S. Debtor's Tax Attributes in an
amount equal to the difference between the consideration transferred in
satisfaction of the discharged Claims and the amount of the discharged indebted
ness. For these purposes, the amount of consideration transferred will be the
sum of (i) any cash (including any cash from the Net Asset Sale Proceeds Pool),
(ii) the "issue price" of any new debt instruments exchanged for Claims, and
(iii) the fair market value of any New Common Shares exchanged for Claims. Based
on its intended reporting positions, PSI expects the amount of discharged
indebtedness under the Canadian Reorganization Plan to result in a significant
reduction in the U.S. Debtors' Tax Attributes, including the elimination of
PSI's NOLs.

         2.         Deductions of Accrued Interest and Original Issue Discount
                    by PSI and Affiliates

                    To the extent a portion of the consideration issued to
Creditors pursuant to the Canadian Reorganization Plan is attributable to
accrued and unpaid interest on their Claims, the relevant U.S. Debtor satisfying
such Claim would be entitled to interest deductions in the amount of such
accrued interest, assuming it has not already deducted such amounts. Under
present law, the amount of consideration which is treated as paid in respect of
accrued interest is unclear where Creditors are receiving less than the full
principal amount of their Claims; however, the Debtor intends to treat the full
amount of the consideration transferred to Creditors pursuant to the Canadian
Reorganization Plan as paid in respect of the principal amount of such
Creditors' Claims and to take the position that no amount of the consideration
to be received by Creditors pursuant to the Canadian Reorganiza tion Plan is
attributable to accrued and unpaid interest on such Creditors' Claims.

B.       U.S. FEDERAL INCOME TAX CONSEQUENCES TO HOLDERS OF ALLOWED CLASS 6 AND
         ALLOWED CLASS 7 CLAIMS

         1.         Allowed Class 6 Claims

                    The U.S. federal income tax consequences of the Canadian
Reorganization Plan to a Class 6 Creditor receiving New Senior Secured Term
Debt, New Secured PIK Debt, New Common Shares, the Net Asset Sale Proceeds Pool
and potentially New Unsecured PIK Notes (the New Senior Secured Term Debt, New
Secured PIK Debt and New Unsecured PIK Notes, as applicable, are referred to in
this Section "Allowed Class 6 Claims" as the "New Debt") will depend on a number
of factors, including whether the New Debt is properly classified as debt or
equity for U.S. federal income tax purposes, whether the debt under the
Pre-Petition Credit Agreement (the "Old Senior Secured Term Debt") or the New
Debt are "securities" of the same issuer for U.S. federal income tax purposes (a
"Tax Security"), and whether the Old Senior Secured Term Debt or New Debt are
considered traded on an established securities market ("publicly traded") for
purposes of the original issue discount rules. The Debtor's
intended position with respect to each of these factors is briefly discussed
below; however, Class 6 Creditors are urged to consult their tax advisors with
respect to these factors.

                                       92

<PAGE>   103

                    Although the matter is not free from doubt, the Debtor
intends to (i) treat the New Debt as debt for U.S. federal income tax purposes,
(ii) take the position that the Old Senior Secured Term Debt is not a Tax
Security, (iii) take the position that the Old Senior Secured Term Debt, the New
Senior Secured Term Debt and the New Secured PIK Debt are not publicly traded
for purposes of the original issue discount rules and (iv) take the position
that the New Unsecured PIK Notes are publicly traded for purposes of the
original issue discount rules. Since the determination of whether a debt
obligation is publicly traded depends on the nature of the trading in such debt
obligation once issued, the determination of whether the New Debt is publicly
traded cannot be made with certainty at this time.

                    The defined term "New Debt" is used to simplify the
following discussion. However, where the tax treatment of the New Debt is
discussed below, such treatment applies separately to each instrument included
in the defined term "New Debt".

                    (a)    General

                           Pursuant to the Canadian Reorganization Plan,
holders of Allowed Class 6 Claims will exchange the Old Senior Secured Term Debt
for the New Debt, New Common Shares and the Net Asset Sale Proceeds Pool. Based
on the intended position that the Old Senior Secured Term Debt is not a Tax
Security, a Class 6 Creditor generally should recognize gain or loss on the
exchange of the Old Senior Secured Term Debt for the New Debt and New Common
Shares equal to the difference between (A) (i) the sum of the issue price of the
New Debt, the fair market value of the New Common Shares and any cash received
less (ii) any amounts attributable to accrued and unpaid interest on the Old
Senior Secured Term Debt and (B) the holder's tax basis in the Old Senior
Secured Term Debt. The characterization of such gain or loss will depend on the
holder's tax position and circumstances, including whether the Class 6 Claim is
a "market discount" obligation. Class 6 Creditors are strongly urged to consult
their tax advisors regarding the characterization of any gain or loss recognized
as a result of the Canadian Reorganization Plan.

                           The Debtor believes that the issue prices of the
New Senior Secured Term Debt and New Secured PIK Debt should be determined under
section 1274(a) of the Tax Code and should equal their respective stated
principal amounts, and the issue price of the New Unsecured PIK Notes should be
determined under section 1273 of the Tax Code and should equal their fair market
value. The holder of a Class 6 Claim generally should have an initial tax basis
in the New Senior Secured Term Debt, New Secured PIK Debt and New Unsecured PIK
Notes equal to their respective issue prices and an initial tax basis in the New
Common Shares equal to their fair market value. The holding period with respect
to each instrument should begin on the day following the day on which the Class
6 Creditor has the right to receive it.

                           If the New Unsecured PIK Notes are not publicly
traded for purposes of the original issue discount ("OID") rules then the issue
price of the New Unsecured PIK Notes would be the lesser of the face amount of
the New Unsecured PIK Notes or the amount of all payments under the New
Unsecured PIK Notes discounted at the applicable federal rate.

                    (b)    Accrued Interest on the Old Senior Secured Term Debt

                           As discussed in "U.S. Federal Income Tax Consequences
to the Debtors" above, although the manner in which consideration paid in
respect of accrued but unpaid interest and principal of the Old Senior Secured
Term Debt is unclear, the Debtor intends to take the position that the full
amount of consideration distributed to the Class 6 Creditors pursuant to the
Canadian Reorganization Plan is allocable to the principal amount of such
Creditors' Claims and to take the position that no amount of the consideration
to be distributed is allocable to accrued but unpaid interest on such Creditors'
Claims.

                           A Class 6 Creditor that previously included in income
accrued but unpaid interest attributable to Old Senior Secured Term Debt should
recognize an ordinary loss to the extent that such previously included accrued
interest exceeds the amount of consideration received by the Creditor which is
attributable to accrued interest for U.S. federal income tax purposes. If and to
the extent that, contrary to the Debtor's intended position, a portion of the
consideration received by a Class 6 Creditor which it has not previously
included in its income as accrued but unpaid interest attributable to the Old
Senior Secured Term Debt is treated for U.S. federal income tax purposes as
attributable to accrued but unpaid interest, the Creditor will recognize
ordinary income in the amount of such interest, regardless of whether the
Creditor realizes an overall gain or loss upon the surrender of its Claim or
whether such gain or loss is recognized.

                           If a Class 6 Creditor is treated as having received
consideration in satisfaction of accrued interest on the Old Senior Secured Term
Debt, then the Creditor's basis in the portion of the consideration received
which is treated as received in satisfaction of accrued interest should be equal
to the amount of interest income treated as satisfied by the receipt of such
consideration. Additionally, a Creditor's tax holding period in such
consideration should begin on the day following the date on which it has a right
to receive such consideration.

                    (c)    Original Issue Discount on the New Senior Secured
                           Term Debt

                           Assuming that the New Debt is properly characterized
as debt for U.S. federal income tax purposes, it would be treated as issued with
OID to the extent its "stated redemption price at maturity" exceeds its "issue
price". An instrument's stated redemption price at maturity includes all
payments required to be made over the term of the instrument other than payments
of "qualified stated interest," defined as interest payments required to be made
at fixed periodic intervals of one year or less (other than interest payable in
debt instruments of the issuer). The interest payments on the New Senior Secured
Term Debt should constitute qualified stated interest only to the extent of $20
million (i.e., the amount required to be made each year over the term of the
debt instrument). The interest payments on the New Secured PIK Debt and the New
Unsecured PIK Notes should not constitute qualified stated interest because they
are payable in kind and/or payments in cash which are not made at least
annually. Accordingly, the stated redemption price at maturity of the New Debt
should equal their respective stated principal amounts plus all interest
payments (other than payments of qualified stated interest) required to be made
under the New Debt.

                           The determination of the "issue price" of the New
Debt depends on whether either the Old Senior Secured Term Debt or the New Debt
is publicly traded for purposes of the OID rules. As stated above, although the
matter is not free from doubt, the Debtor believes that the issue price of the
New Senior Secured Term Debt and New Secured PIK Debt would be determined by
reference to the rules applicable to debt that is not traded on an established
securities market. Accordingly, the issue price of the New Senior Secured Term
Debt and New Secured PIK Debt generally would be their stated principal amount
under section 1274(a) of the Tax Code.

                           As stated earlier, although the matter is not free
from doubt, the Debtor intends to take the position that the New Unsecured PIK
Notes will be publicly traded for purposes of the OID rules. Conse quently,
under section 1273 of the Tax Code, the issue price of the New Unsecured PIK
Notes would be equal to their fair market value on the issue date. If, contrary
to the Debtor's intended position, the issue price of the New Unsecured PIK
Notes was ultimately determined to be determined by reference to the rules
governing non-publicly traded debt instruments, the amount of OID and other
consequences to holders would likely differ from those resulting from the
application of section 1273 of the Tax Code.

                           A holder of a debt instrument that bears OID is
required to include in gross income an amount equal to the sum of the daily
portions of OID for each day during the taxable year in which the debt
instrument is held. The daily portions of OID are determined by allocating to
each day in an accrual period the pro rata portion of the OID that is considered
allocable to the accrual period. The amount of OID that is allocable to an
accrual period is generally equal to (A) the product of the adjusted issue price
of the New Debt at the beginning of

                                       94

<PAGE>   105

the accrual period (the issue price of the New Debt increased by prior accruals
of OID and decreased by prior cash payments other than payments of qualified
stated interest) and its yield-to-maturity (the discount rate, which when
applied to all payments under the New Debt, results in a present value equal to
the issue price of the New Debt) less (B) the amount of qualified stated
interest allocable to that accrual period.

                           The general effect of the OID rules is that holders,
including holders that use a cash-basis method of accounting, will be required
to accrue OID as interest income with respect to the New Debt over the life of
the New Debt based on its yield-to-maturity. Cash payments (other than payments
of qualified stated interest) on the New Debt are not separately included in a
holder's income as interest, but rather are treated first as payments of
previously accrued OID and then as payments of principal.

                           As noted above, the issuance of additional New
Unsecured PIK Notes will not be treated as a payment of interest. Instead, the
underlying New Unsecured PIK Notes and any additional New Unsecured PIK Notes
that may be issued thereon are treated as a single debt instrument under the OID
rules. Moreover, the issuance of any additional New Unsecured PIK Notes should
be treated simply as a division of the underlying New Unsecured PIK Notes, so
that the holder's tax basis and adjusted issue price in the underlying
instruments should be allocated among the underlying instruments and the
additional instruments in proportion to their relative principal amounts.

                    (d)    Adjustment of Conversion Price of New Secured PIK
                           Debt

                           The conversion ratio of the New Secured PIK Debt is
subject to adjustment under certain circumstances. Section 305 of the Tax Code,
and the Treasury Regulations issued thereunder, may treat holders of New Secured
PIK Debt as having received a constructive distribution, resulting in ordinary
income to the extent of PSC's current and accumulated earnings and profits (as
determined for U.S. federal income tax purposes), if, and to the extent that,
certain adjustments of the conversion ratio increase the proportionate interest
of a holder in the fully diluted share ownership of PSC, whether or not such
holder exercises the conversion privilege. Moreover, if there is not a full
adjustment of the conversion ratio of the New Secured PIK Debt to reflect a
stock dividend or other event that increases the proportionate interest of
holders of outstanding New Common Shares in the assets or earnings and profits
of PSC, then such increase in the proportionate interest of holders of New
Common Shares generally will be treated as a taxable distribution to such
holders with respect to their New Common Shares.

                    (e)    Conversion of New Secured PIK Debt into New Common
                           Shares

                           In general, no gain or loss will be recognized for
U.S. federal income tax purposes upon a conversion of the New Secured PIK Debt
into New Common Shares. However, cash paid in lieu of a fractional share of New
Common Shares will result in taxable gain (or loss) to the extent that the
amount of such cash exceeds (or is exceeded by) the portion of the adjusted tax
basis of the New Secured PIK Debt allocable to such fractional share. The
initial tax basis of New Common Shares received on conversion of the New Secured
PIK Debt will equal the adjusted tax basis of the converted New Secured PIK Debt
on the date of conversion, reduced by the portion of such adjusted tax basis
allocated to any fractional share of New Common Shares considered to be
exchanged for cash. The holding period for New Common Shares received on
conversion will include the period during which the converted New Secured PIK
Debt was held.

                    (f)    Sale, Exchange or Redemption of New Common Shares
                           and New Debt

                           The sale or exchange of New Common Shares generally
should result in capital gain or loss equal to the difference between the amount
realized and the holder's tax basis in such New Common Shares. Depending upon
the circumstances, a redemption by PSC of New Common Shares may result in
capital gain or loss to the holder of such security, or may be treated as a
dividend, generally taxable as ordinary income to the holder to the extent of
PSC's earnings and profits (as determined for U.S. federal income tax purposes)
at the time of the redemption.

                                       95

<PAGE>   106

                           In general, the sale, exchange or redemption of the
New Debt by a Class 6 Creditor (except for exchanges of New Secured PIK Debt for
New Common Shares as discussed above) would result in capital gain or loss equal
to the difference between the amount realized and the holder's tax basis in such
New Debt.

         2.         Allowed Class 7 Claims

                    The U.S. federal income tax consequences of the Canadian
Reorganization Plan to a Class 7 creditor receiving New Unsecured PIK Notes
and/or New Unsecured Convertible Notes (the New Unsecured PIK Notes and New
Unsecured Convertible Notes, as applicable, are referred to in this Section
"Allowed Class 7 Claims" as the "New Notes") and New Common Shares will depend
on a number of factors, including whether the New Notes are properly classified
as debt or equity for U.S. federal income tax purposes, whether the exchanged
Claim and New Notes are both "securities" of PSC for U.S. federal income tax
purposes (a PSC "Tax Security"), and whether the exchanged Claims or New Notes
are considered traded on an established securities market ("publicly traded")
for purposes of the original issue discount rules. PSC's intended position
regarding the New Notes with respect to each of these factors is briefly
discussed below; however, Class 7 creditors are urged to consult their tax
advisors with respect to these factors. Additionally, whether any of the
exchanged Claims is a Tax Security or publicly traded depends on the facts and
circumstances of each exchanged Claim, and Class 7 creditors are urged to
consult their tax advisors with respect to these factors.

                    Although the matter is not free from doubt, the Debtor
intends to (i) treat the New Notes as debt for U.S. federal income tax purposes,
(ii) take the position that the New Notes are Tax Securities and (iii) take the
position that the New Notes are publicly traded for purposes of the original
issue discount rules. Since the determination of whether a debt obligation is
publicly traded depends on the nature of the trading in such debt obligation
once issued, the determination of whether the New Notes are publicly traded
cannot be made with certainty at this time.

                    The defined term "New Notes" is used to simplify the
following discussion. However, where the tax treatment of the New Notes is
discussed below, such treatment applies separately to each instrument included
in the defined term "New Notes".

                    (a)     General

                           Pursuant to the Canadian Reorganization Plan, holders
of Allowed Class 7 Claims will exchange their Claims for the New Notes and New
Common Shares. Generally, a Class 7 creditor will not recognize gain or loss on
its exchange if the Creditor's exchanged Claim is a PSC Tax Security. Whether an
instrument constitutes a Tax Security is determined based on all the facts and
circumstances. Certain authorities have held that the length of the term of a
debt instrument is a factor in determining whether such instrument is a Tax
Security for U.S. federal income tax purposes. These authorities have indicated
that a term of less than five years is evidence that the instrument is not a Tax
Security, whereas a term of ten years or more is evidence that it is a Tax
Security. In addition, claims in the nature of legal actions, accounts
receivable or bank loans generally are not treated as Tax Securities; whereas,
bonds, notes or other evidences of indebtedness issued to investors with a term
of at least ten years generally are treated as Tax Securities.

                           Holders of Allowed Class 7 Claims whose exchanged
Claims are PSC Tax Securities generally should not recognize gain or loss with
respect to the exchange of such Claims for New Notes and New Common Shares
because such exchanges should constitute a recapitalization pursuant to a plan
of reorganization within the meaning of section 368(a)(1)(E) of the Tax Code.
Accordingly, with respect to such exchanges, such holders should (i) allocate
their basis in their exchanged Claims to the New Notes and New Common Shares
based on the relative fair market value of such securities, and (ii) have tax
holding periods for the New Notes and New Common Shares received in exchange for
their exchanged Claims that include their tax holding periods for such exchanged
Claims (except to the extent such securities are attributable to accrued
interest).

                                       96

<PAGE>   107

                           Holders of Allowed Class 7 Claims whose exchanged
Claims are not PSC Tax Securities (including all holders of Class 7 Claims whose
Claims are against specific entities other than PSC itself) generally should
recognize gain or loss on the exchange of such Claims for the New Notes and New
Common Shares equal to the difference between (A) (i) the sum of the issue price
of the New Notes and the fair market value of the New Common Shares received
less (ii) any amounts attributable to accrued and unpaid interest on the
exchanged Claims and (B) the holder's tax basis in the exchanged Claims.
Accordingly, with respect to such exchanges, such holders should have an initial
tax basis in the New Unsecured PIK Notes and New Unsecured Convertible Notes
equal to their respective issue prices and an initial tax basis in the New
Common Shares equal to their fair market value. The holding period with respect
to each instrument should begin on the day following the day on which the
Creditor has the right to receive it. The characterization of such gain or loss
will depend on the holder's tax position and circumstances, including whether
the Class 7 Claim is a "market discount" obligation. Class 7 creditors are
strongly urged to consult their tax advisors regarding the characterization of
any gain or loss recognized as a result of the Canadian Reorganization Plan.

                           The determination of the "issue price" of the New
Notes depends on whether the New Notes are publicly traded for purposes of the
OID rules. As stated above, although the matter is not free from doubt, the
Debtor believes that the New Notes will be publicly traded for purposes of the
OID rules. Accordingly, the issue price of the New Notes should be equal to
their fair market value on the issue date as determined under section 1273 of
the Tax Code.

                           If the New Notes are not publicly traded for purposes
of the OID rules (and a "substantial amount" of the exchanged Claims are not
publicly traded for purposes of the OID rules, which the Debtor believes to be
the case) then the issue price of the New Notes would be the lesser of the face
amount of the New Notes or the amount of all payments under the New Notes
discounted at the applicable federal rate.

                    (b)    Accrued Interest on Unsecured Claims

                           Although the manner in which consideration is to be
allocated between accrued but unpaid interest and principal of the unsecured
Claims for U.S. federal income tax purposes is unclear, the Debtor intends to
take the position that the full amount of the consideration distributed to Class
7 creditors pursuant to the Canadian Reorganization Plan is allocable to the
principal amount of such Creditors' Claims and to take the position that no
amount of consideration to be distributed is allocable to accrued but unpaid
interest on such Creditors' Claims.

                           A Class 7 creditor that previously included in income
accrued but unpaid interest attributable to its unsecured Claims should
recognize an ordinary loss to the extent that such previously included accrued
interest exceeds the amount of consideration received by the Creditor which is
attributable to accrued interest for U.S. federal income tax purposes. If and to
the extent that, contrary to the Debtor's intended position, a portion of the
consideration received by a Class 7 creditor which it has not previously
included in its income as accrued but unpaid interest attributable to its
unsecured Claims is treated for U.S. federal income tax purposes as attributable
to accrued but unpaid interest, such Creditor will recognize ordinary income in
the amount of such interest, regardless of whether the Creditor realizes an
overall gain or loss upon the surrender of its Claim or whether such gain or
loss is recognized.

                           If a Class 7 creditor is treated as having received
consideration in satisfaction of accrued interest on the unsecured Claims, then
the Creditor's basis in the portion of the New Notes treated as received in
satisfaction of accrued interest on the unsecured Claims should be equal to the
amount of interest income treated as satisfied by the receipt of such
instruments. Additionally, a Creditor's tax holding period in the New Notes
should begin on the day following the date on which it has a right to receive
them.

                                       97

<PAGE>   108

                    (c)    Original Issue Discount on the New Notes

                           Assuming that the New Notes are properly
characterized as debt instruments for U.S. federal income tax purposes, they
would be treated as issued with OID to the extent their "stated redemption price
at maturity" exceeds their "issue price". An instrument's stated redemption
price at maturity includes all payments required to be made over the term of the
instrument other than payments of "qualified stated interest," defined as
interest payments required to be made at fixed periodic intervals of one year or
less (other than interest payable in debt instruments of the issuer). The
interest payments on the New Notes should not constitute qualified stated
interest because they are payable in kind and/or payments in cash which are not
made at least annually. Accord ingly, the stated redemption price at maturity of
the New Notes should equal their stated principal amount plus all interest
payments required to be made under the New Notes.

                           The determination of the "issue price" of the New
Notes depends on whether the New Notes are publicly traded for purposes of the
OID rules. As stated above, although the matter is not free from doubt, the
Debtor intends to take the position that the New Notes will be publicly traded
for purposes of the OID rules. Consequently, the issue price of the New Notes
should be equal to their fair market value on the issue date. If, contrary to
the Debtor's intended position, the issue price of the New Notes was ultimately
determined to be determined by reference to the rules governing non-publicly
traded debt instruments, the issue price would likely differ from those
resulting from the application of section 1273 of the Tax Code.

                           A holder of a debt instrument that bears OID is
required to include in gross income an amount equal to the sum of the daily
portions of OID for each day during the taxable year in which the debt
instrument is held. The daily portions of OID are determined by allocating to
each day in an accrual period the pro rata portion of the OID that is considered
allocable to the accrual period. The amount of OID that is allocable to an
accrual period is generally equal to the product of the adjusted issue price of
the New Notes at the beginning of the accrual period (the issue price of the New
Notes increased by prior accruals of OID and decreased by prior cash payments)
and its yield-to-maturity (the discount rate, which when applied to all payments
under the New Notes, results in a present value equal to the issue price of the
New Notes).

                           The general effect of the OID rules is that holders,
including holders that use a cash-basis method of accounting, will be required
to accrue OID as interest income with respect to the New Notes over the life of
the New Notes based on their yield-to-maturity (which may differ from the stated
interest rate of the New Notes).

                           As noted above, the issuance of additional New
Unsecured PIK Notes will not be treated as a payment of interest. Instead, the
underlying New Unsecured PIK Notes and any additional New Unsecured PIK Notes
that may be issued thereon are treated as a single debt instrument under the OID
rules. Moreover, the issuance of any additional New Unsecured PIK Notes should
be treated simply as a division of the underlying New Unsecured PIK Notes, so
that the holder's tax basis and adjusted issue price in the underlying New
Unsecured PIK Notes should be allocated among underlying New Unsecured PIK Notes
and the additional New Unsecured PIK Notes in proportion to their relative
principal amounts.

                    (d)    Bond Premium on New Notes

                           A holder that has a tax basis in its New Notes in
excess of the issue price of such bonds should be permitted to reduce its
original issue discount income with respect to such bonds by a ratable portion
of such excess. Class 7 creditors having a relatively high basis in their
unsecured Claims should be able to offset a substantial portion of their
original issue discount income with respect to the New Notes by amortizing this
premium. Additionally, in general, if the tax basis of New Notes in the hands of
a Class 7 creditor exceeds the stated redemption price at maturity of such New
Notes (which may occur for Class 7 creditors who receive recapitalization
treatment in the exchange because they hold exchanged Claims which are PSC Tax
Securities), the New Notes will be considered to be issued with "bond premium".
To amortize bond premium, the holder must make an election that

                                       98

<PAGE>   109

applies to all debt instruments it holds or subsequently acquires. A holder that
elects to amortize bond premium must reduce its tax basis in the New Notes by an
amount equal to the amortized premium.

                    (e)    Market Discount on New Notes

                           The Tax Code generally requires holders of debt
instruments with "market discount," (generally, the amount by which the "revised
issue price" of a debt instrument (i.e., the sum of its issue price plus accrued
original issue discount) exceeds the holder's adjusted tax basis in such debt
instrument), to treat as ordinary income any gain realized on the disposition of
such debt instruments to the extent of the market discount accrued during the
holder's period of ownership. Holders should consult their own tax advisors as
to the potential application of the market discount rules to them in light of
their individual circumstances, and the advisability of making an election to
accrue market discount on a current basis.

                    (f)    Adjustment of Conversion Price of New Unsecured
                           Convertible Notes

                           The conversion ratio of the New Unsecured Convertible
Notes is subject to adjustment under certain circumstances. Section 305 of the
Tax Code, and the Treasury Regulations issued thereunder, may treat holders of
New Unsecured Convertible Notes as having received a constructive distribution,
resulting in ordinary income to the extent of PSC's current and accumulated
earnings and profits (as determined for U.S. federal income tax purposes), if,
and to the extent that, certain adjustments of the conversion ratio increase the
proportion ate interest of a holder in the fully diluted share ownership of PSC,
whether or not such holder exercises the conversion privilege. Moreover, if
there is not a full adjustment of the conversion ratio of the New Unsecured
Convertible Notes to reflect a stock dividend or other event that increases the
proportionate interest of holders of outstanding New Common Shares in the assets
or earnings and profits of PSC, then such increase in the proportion ate
interest of holders of New Common Shares generally will be treated as a taxable
distribution to such holders with respect to their New Common Shares.

                    (g)    Conversion of New Unsecured Convertible Notes into
                           New Common Shares

                           In general, no gain or loss will be recognized for
U.S. federal income tax purposes upon a conversion of New Unsecured Convertible
Notes into New Common Shares. However, cash paid in lieu of a fractional share
of New Common Shares, if any, will result in taxable gain (or loss) to the
extent that the amount of such cash exceeds (or is exceeded by) the portion of
the adjusted tax basis of the New Unsecured Convertible Note allocable to such
fractional share. The initial tax basis of New Common Shares received on
conversion of the New Unsecured Convertible Notes will equal the adjusted tax
basis of the converted New Unsecured Convertible Notes on the date of
conversion, reduced by the portion of such adjusted tax basis allocated to any
fractional share of New Common Shares considered to be exchanged for cash. The
holding period for New Common Shares received on conversion will include the
period during which the converted New Unsecured Convertible Notes were held.

                    (h)    Sale, Exchange or Redemption of New Common Shares
                           and New Notes

                           The sale or exchange of New Common Shares generally
should result in capital gain or loss equal to the difference between the amount
realized and the holder's tax basis in such New Common Shares. Depending upon
the circumstances, a redemption by PSC of New Common Shares may result in
capital gain or loss to the holder of such security, or may be treated as a
dividend, generally taxable as ordinary income to the holder to the extent of
PSC's earnings and profits (as determined for U.S. federal income tax purposes)
at the time of the redemption.

                           In general, assuming the New Notes are properly
treated as debt for U.S. federal income tax purposes, and subject to the market
discount rules discussed above, the sale, exchange or redemption of the New
Notes by a Class 7 creditor (except for exchanges of New Unsecured Convertible
Notes for New Common Shares as

                                       99

<PAGE>   110

discussed above) would result in capital gain or loss equal to the difference
between the amount realized and the holder's tax basis in such New Notes.

         3.         Importance of Obtaining Professional Tax Assistance

                    THE FOREGOING IS INTENDED TO BE ONLY A GENERAL SUMMARY OF
CERTAIN OF THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE CANADIAN
REORGANIZATION PLAN, AND IS NOT A SUBSTITUTE FOR CAREFUL TAX PLANNING WITH A TAX
PROFESSIONAL. THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE CANADIAN
REORGANIZATION PLAN WHICH ARE DESCRIBED HEREIN AND THE STATE, LOCAL AND FOREIGN
TAX CONSEQUENCES (INCLUDING CANADA INCOME TAX, WITHHOLDING TAX AND OTHER
CONSEQUENCES) OF THE CANADIAN REORGANIZATION PLAN WHICH ARE NOT ADDRESSED
HEREIN, ARE COMPLEX AND, IN SOME CASES, UNCERTAIN. SUCH CONSEQUENCES MAY ALSO
VARY SIGNIFICANTLY BASED ON THE INDIVIDUAL CIRCUMSTANCES OF EACH HOLDER OF A
CLAIM. ACCORDINGLY, EACH HOLDER OF A CLAIM IS STRONGLY URGED TO CONSULT WITH ITS
TAX ADVISOR REGARDING THE SPECIFIC U.S. FEDERAL, STATE, LOCAL AND FOREIGN TAX
CONSEQUENCES OF THE CANADIAN REORGANI ZATION PLAN, INCLUDING ANY CANADA INCOME
OR WITHHOLDING TAX CONSEQUENCES TO IT.

                    THE FOREGOING SUMMARY DOES NOT REVIEW THE U.S. FEDERAL
INCOME TAX CONSEQUENCES OF, OR ANY OTHER CONSIDERATIONS RELATING TO, THE
ALTERNATE CANADIAN TRANSACTIONS. AS THESE MAY BE DIFFERENT IN MATERIAL RESPECTS
FROM THOSE OF THE CANADIAN REORGANIZATION PLAN WHICH ARE DESCRIBED ABOVE,
CREDITORS ARE URGED AND EXPECTED TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT
TO THE ALTERNATE CANADIAN TRANSACTIONS.

C.       CERTAIN CANADIAN FEDERAL INCOME TAX CONSEQUENCES OF THE PLAN

         The following is a summary of certain Canadian federal income tax
considerations generally applicable to PSC and to holders of indebtedness to
which Allowed Class 6 Claims and Allowed Class 7 Claims ("Old Debt") relate, who
receive proceeds out of the Net Asset Sale Proceeds Pool or New Senior Secured
Term Debt, New Secured PIK Debt, New Unsecured PIK Notes or New Unsecured
Convertible Notes ("New Debt") or New Common Shares, as the case may be,
pursuant to the implementation of the Canadian Reorganization Plan
(collectively, "New Property"), and who, at all relevant times, for the purposes
of the Income Tax Act (Canada) (the "Tax Act"), hold Old Debt and New Property
as capital property and deal at arm's length and are not affiliated with PSC
("Holders"). Generally, property will be considered to be capital property to a
Holder provided that the Holder does not hold the property in the course of
carrying on a business and has not acquired it in a transaction or transactions
considered to be an adventure in the nature of trade. Certain Resident Holders
(as defined below) whose New Common Shares might not otherwise qualify as
capital property may be entitled to obtain such qualification by making the
irrevocable election permitted by subsection 39(4) of the Tax Act. A Holder that
is, as defined under the Tax Act, a "specified financial institution", or a
"financial institution" subject to special provisions of the Tax Act applicable
to "mark-to-market property", should consult its own tax advisors as the
following summary does not apply to such a Holder.

         This summary is based upon the current provisions of the Tax Act, the
regulations thereunder, all specific proposals to amend the Tax Act and the
regulations publicly announced by or on behalf of the Minister of Finance
(Canada) prior to the date hereof. This summary does not otherwise take into
account or anticipate any changes in law, whether by legislative, governmental
or judicial decision or action, nor does it take into account or consider any
provincial, territorial or foreign income tax consequences.

         NO ADVANCE INCOME TAX RULINGS HAVE BEEN REQUESTED FROM REVENUE CANADA
WITH RESPECT TO ANY INCOME TAX CONSEQUENCES OF THE CANADIAN REORGANIZATION PLAN
AND NO OPINION OF COUNSEL HAS BEEN SOUGHT OR OBTAINED

WITH RESPECT TO SUCH CONSEQUENCES. NO REPRESENTATIONS REGARDING THE PARTICULAR
TAX CONSEQUENCES OF THE IMPLEMENTATION OF THE CANADIAN REORGANIZATION PLAN TO
ANY HOLDER ARE BEING MADE.

         THE SUMMARY IS OF A GENERAL NATURE ONLY AND IS NOT INTENDED TO BE, NOR
SHOULD IT BE CONSTRUED TO BE, LEGAL OR TAX ADVICE TO ANY HOLDER. ACCORDINGLY,
HOLDERS ARE URGED AND EXPECTED TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO
THEIR PARTICULAR CIRCUMSTANCES.

         THIS SUMMARY DOES NOT REVIEW THE CANADIAN FEDERAL INCOME TAX
CONSEQUENCES OF, OR ANY OTHER CONSIDERATIONS RELATING, TO THE ALTERNATE CANADIAN
TRANSACTIONS, AS THESE MAY BE DIFFERENT IN MATERIAL RESPECTS FROM THOSE OF THE
CANADIAN REORGANIZATION PLAN WHICH ARE DESCRIBED BELOW, HOLDERS ARE URGED AND
EXPECTED TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE ALTERNATE
CANADIAN TRANSACTIONS.

         1.         Certain Federal Income Tax Consequences to PSC

                    The Canadian Reorganization Plan will result in the
forgiveness of certain of PSC's indebted ness. Such forgiveness will reduce, in
prescribed order, certain tax attributes of PSC and, if appropriate agreements
and tax designations have been filed as prescribed by the Tax Act, certain tax
attributes of taxable Canadian corporations controlled by PSC. Tax attributes
reduced as a result of debt forgiveness include non-capital losses, net capital
losses, cumulative eligible capital, the undepreciated capital cost of
depreciable property and the adjusted cost base of certain capital property (the
"Tax Shield"). Generally, three-quarters of the amount by which the debt
forgiveness exceeds the Tax Shield will be required to be included in PSC's
income for the taxation year in which the debt forgiveness takes place. PSC
believes that the implementation of the Canadian Reorganization Plan should not
result in any amount being required to be included in its income or in the
income of any taxable Canadian corporation controlled by it.

         2.         Certain Federal Income Tax Consequences to Holders

                    (a)    Non-resident Holders

                           The following is a summary of certain Canadian
federal income tax considerations generally applicable to a Holder who, at all
relevant times, for purposes of the Tax Act and any applicable income tax
treaty, is not and is not deemed to be a resident of Canada and does not use or
hold and is not deemed to use or hold Old Debt or New Property in carrying on a
business in Canada (a "Non-resident Holder"). Special rules, which are not
discussed in this summary, may apply to a Non-resident Holder that is an insurer
carrying on business in Canada and elsewhere.

                           (i)      Receipt of New Property

                                    A Non-resident Holder who pursuant to
either Plan New Property in full or partial satisfaction of the outstanding
principal amount of Old Debt should not be subject to tax in respect of such
receipt and should acquire the New Property for a cost equal to its then fair
market value.

                           (ii)     Withholding Tax

                                    Interest which is or is deemed to be paid
or credited PSC to a Non-resident Holder on New Debt may be subject to
withholding tax under the Tax Act, depending on the final terms and conditions
of such New Debt. Based on the current draft terms and conditions of the New
Debt, the following consequences should arise.

                                    Interest which is or is deemed to be paid or
credited by PSC to a Non-resident Holder on New Secured PIK Debt will be subject
to withholding tax under the Tax Act. Interest which is or is

                                       101

<PAGE>   112

deemed to be paid or credited by PSC to a Non-resident Holder on New Unsecured
PIK Notes issued in full or partial satisfaction of the outstanding principal
amount of Old Debt should not be subject to withholding tax under the Tax Act.
However, interest which is or is deemed to be paid or credited, whether in cash
or kind, by PSC to a Non-resident Holder on New Unsecured PIK Notes issued from
time to time as payment in kind in respect of PSC's obligation to pay interest
on any New Unsecured PIK Notes will be subject to withholding tax under the Tax
Act if the principal amount of such notes is payable within 5 years from the
date on which they are issued. Interest which is or is deemed to be paid or
credited by PSC to a Non-resident Holder on New Unsecured Convertible Notes may,
depending on their terms and conditions, be subject to withholding tax under the
Tax Act. Certain dispositions of New Debt, including to PSC upon repayment, may
result in interest being deemed to have been paid to a Nonresident Holder.

                                    Withholding tax is imposed under the Tax
Act at a rate of twenty-five percent (25%) of the amount of interest which is or
is deemed to be paid or credited, subject to reduction in accordance with the
provisions of any applicable tax treaty. Under the Canada-United States Income
Tax Convention, the rate of withholding tax in respect of interest is generally
reduced to ten percent (10%).

                           (iii)    Conversions

                                    A Non-resident Holder of New Secured PIK
Notes or New Unsecured Convertible Notes who converts such notes into New Common
Shares will generally be treated as not having disposed on the notes and the
cost of the New Common Shares to such Non-resident Holder will be equal to the
aggregate adjusted cost base to the Non-resident Holder of the converted notes
immediately before the conversion.

                           (iv)     Dispositions

                                    A Non-resident Holder will not be subject to
tax under the Tax Act on any capital gain realized on the disposition of New
Unsecured PIK Notes. A Non-resident Holder will not be subject to tax under the
Tax Act on any capital gain realized on a disposition of New Common Shares, New
Convertible Notes or New Secured PIK Notes unless the shares constitute "taxable
Canadian property" at the time of their disposition. New Common Shares, provided
they are and continue to be listed on a prescribed stock exchange (which
includes the Toronto Stock Exchange), generally will not constitute taxable
Canadian property to a Non-resident Holder unless at any time during the
60-month period immediately preceding their disposition, the Non-resident
Holder, persons with whom the Non-resident Holder did not deal at arm's length,
or the Non-resident Holder together with all such persons, owned twenty-five
percent (25%) or more of the issued shares of any class of PSC. For this
purpose, a Non-resident Holder will be considered to own any share if such
person has an interest in or option or other right to acquire such share, either
by virtue of holding New Unsecured Convertible Notes or New Secured PIK Notes or
otherwise.

                    (b)    Resident Holders

                           The following is a summary of certain Canadian
federal income tax considerations generally applicable to a Holder who, at all
relevant times, for purposes of the Tax Act and any applicable tax treaty, is or
is deemed to be a resident of Canada (a "Resident Holder").

                           (i)      Receipt of New Property

                                    A Resident Holder who receives New Property
in full or partial satisfaction of the outstanding principal amount of Old Debt
will be treated as having disposed of an interest in the Old Debt for proceeds
of disposition equal to the aggregate fair market value of the New Property so
received, and should be treated as having a cost in such New Property equal to
its fair market value. Generally, such disposition will give rise to a capital
gain (or capital loss) to the extent that the proceeds of disposition, net of
any reasonable costs of

                                       102

<PAGE>   113

dispositions, exceed (or are less than) the aggregate adjusted cost base to the
Resident Holder, immediately before the disposition, of the interest in the Old
Debt so disposed of.

                           (ii)     Disposition of New Common Shares

                                    A Resident Holder who disposes of New Common
Shares will generally realize a capital gain (or capital loss) to the extent
that the proceeds of disposition therefor, net of any reasonable costs of
disposition, exceed (or are less than) the Resident Holder's aggregate adjusted
cost base immediately before the disposition of the New Common Shares disposed
of.

                                    In the case of a Resident Holder that is a
corporation, the amount of any capital loss otherwise determined on the
disposition of its New Common Shares may in certain circumstances be reduced by
the amount of certain dividends previously received on such New Common Shares,
to the extent and under the circumstances described in the Tax Act. Similar
rules may apply where a corporation, a partnership or a trust is a member of a
partnership or a beneficiary of a trust that owns New Common Shares.

                           (iii)    Interest and Premium on New Debt

                                    A Resident Holder of New Debt that is a
corporation, partnership, unit trust or trust of which a corporation or
partnership is a beneficiary will be required to include in its income for a
taxation year any interest that accrues to the Resident Holder to the end of
that taxation year or becomes receivable or is received by it before the end of
that year, except to the extent that such amount was included in its income for
a preceding taxation year.

                                    Any other Resident Holder of New Debt,
including an individual, will be required to include in income for a taxation
year any interest received or receivable by such holder in that year (depending
upon the method regularly followed by the Resident Holder in computing income),
except to the extent that such amount was included in the Resident Holder's
income for a preceding taxation year.

                                    Any premium paid by the issuer of New Debt
because it exercises its right to redeem the New Debt before maturity thereof
will generally be deemed to be interest received at that time by a Resident
Holder to the extent that such premium can reasonably be considered to relate
to, and does not exceed, the value, at the time of the redemption, of the
interest that would have been paid or payable by such issuer on such redeemed
New Debt for a taxation year ending after the redemption.

                           (iv)     Disposition of New Debt

                                    Where a Resident Holder assigns or otherwise
transfers New Debt, the Resident Holder must include in income for the taxation
year in which the assignment or other transfer occurs, an amount of interest
that has accrued on the New Debt up to that time and that is not payable until
after that time, to the extent that such interest was not otherwise included in
computing the Resident Holder's income for that taxation year or a previous
taxation year.

                                    Where, in a taxation year, a Resident Holder
has disposed of New Debt for consideration equal to its fair market value, the
Resident Holder generally may deduct in computing income for the year such
portion of the total of all amounts included in the Resident Holder's income for
that taxation year or a preceding taxation year as interest on such New Debt as
cannot reasonably be considered to have been received or become receivable by
the Resident Holder in that taxation year or a preceding taxation year. Any
amount so deducted by the Resident Holder in computing income will not reduce
the Resident Holder's capital gain or increase the Resident Holder's capital
loss from the disposition of the New Debt.

                                       103

<PAGE>   114

                                    A Resident Holder who disposes of New Debt
will generally realize capital gain (or capital loss) to the extent that the
proceeds of disposition therefor (which should exclude amounts included in
income in respect of such disposition as interest), net of any reasonable costs
of disposition, exceed (or are less than) the Resident Holder's aggregate
adjusted cost base immediately before the disposition of the New Debt disposed
of.

                           (v)      Conversions

                                    A Resident Holder of New Secured PIK Notes
or New Unsecured Convertible Notes who converts such notes into New Common
Shares will generally be treated as not having disposed of the notes and the
cost of the New Common Shares to such Resident Holder will be equal to the
aggregate adjusted cost base to the Resident Holder of the converted notes
immediately before the conversion.

                           (vi)     Treatment of Capital Gains (or Losses)

                                    Three-quarters of the amount of any capital
gain (a "taxable capital gain") realized by a Resident Holder in a taxation year
generally must be included in income in that year, and three-quarters of the
amount of any capital loss (an "allowable capital loss") realized in a taxation
year must be deducted from taxable capital gains realized by the Resident Holder
in that year. Allowable capital losses in excess of taxable capital gains may be
carried back and deducted in any of the three preceding taxation years or
carried forward and deducted in any following taxation year against net taxable
capital gains realized in such years to the extent and under the circumstances
described in the Tax Act.

                                    Capital gains realized by a Resident Holder
that is an individual or a trust, other than certain specified trusts, may give
rise to alternative minimum tax under the Tax Act.

                                    For the purpose of determining the adjusted
cost base of any New Properties acquired at any time by a Resident Holder, the
cost of such properties will be determined by averaging their cost with the
adjusted cost base of all other identical properties held immediately before the
time of such acquisition by the Holder as capital property.

                           (vii)    Refundable Tax

                                    A Resident Holder that is a
"Canadian-controlled private corporation" (as defined in the Tax Act) may be
liable for a refundable tax of six and two-thirds percent (6 2/3%) on investment
income, including interest and taxable capital gains. This tax will be refunded
when the corporation pays taxable dividends (at a rate of one dollar for every
three dollars of taxable dividends paid).

                           (viii)   Foreign Tax Credit or Deduction

                                    Assuming that the rate of any foreign
withholding tax paid by a Resident Holder in respect of interest received on New
Senior Secured Term Debt does not exceed fifteen percent (15%), such tax will
generally be treated as a foreign income tax eligible for credit against such
Resident Holder's Canadian federal income tax otherwise payable or for deduction
in computing such Resident Holder's income, to the extent and in the
circumstances provided for in the Tax Act. Any such foreign withholding tax paid
by the Resident Holder at a rate exceeding fifteen percent (15%) will generally
be eligible for deduction in computing such Resident Holder's income or, in the
case of a Resident Holder that is not (and for the purposes of the Tax Act is
not treated as) an individual, a credit against such Resident Holder's Canadian
federal income tax otherwise payable, to the extent and in the circumstances
provided for in the Tax Act.

                                  ARTICLE XI.

             FEASIBILITY OF THE PLAN AND BEST INTERESTS OF CREDITORS

A.       FEASIBILITY OF THE PLAN

         In connection with confirmation of the Plan, the Bankruptcy Court will
have to determine that the Plan is feasible pursuant to section 1129(a)(11) of
the Bankruptcy Code, which means that the confirmation of the Plan is not likely
to be followed by the liquidation or the need for further financial
reorganization of the Debtors.

         To support their belief in the feasibility of the Plan, the Debtors
have relied upon Pro Forma Financial Projections for six months ended December
31, 1999 and Fiscal Years 2000 through 2001, as set forth in Appendix F annexed
to this Disclosure Statement.

         The Projections indicate that the Reorganized Debtors should have
sufficient cash flow to pay and service their debt obligations, including the
Exit Facility, and to fund their operations as contemplated by the Business
Plan. Accordingly, the Debtors believe that the Plan complies with the financial
feasibility standard of section 1129(a)(11) of the Bankruptcy Code.

         The Projections were not prepared with a view toward compliance with
the published guidelines of the American Institute of Certified Public
Accountants or any other regulatory or professional agency or body or generally
accepted accounting principles. Furthermore, the Debtors' independent certified
public accountants have not compiled or examined the Projections and accordingly
do not express any opinion or any other form of assurance with respect thereto
and assume no responsibility for the Projections.

         The Projections assume that (i) the Plan will be confirmed and
consummated in accordance with its terms, (ii) there will be no material change
in legislation or regulations, or the administration thereof, including environ
mental legislation or regulations, that will have an unexpected effect on the
operations of the Reorganized Debtors, (iii) there will be no change in United
States generally accepted accounting principles that will have a material effect
on the reported financial results of the Reorganized Debtors, and (iv) there
will be no material contingent or unliquidated litigation or indemnity claims
applicable to the Reorganized Debtors. To the extent that the assumptions
inherent in the Projections are based upon future business decisions and
objectives, they are subject to change. In addition, although they are presented
with numerical specificity and considered reasonable by the Debtors when taken
as a whole, the assumptions and estimates underlying the Projections are subject
to significant business, economic and competitive uncertainties and
contingencies, many of which will be beyond the control of the Reorganized
Debtors. Accordingly, the Projections are only an estimate that are necessarily
speculative in nature. It can be expected that some or all of the assumptions in
the Projections will not be realized and that actual results will vary from the
Projections, which variations may be material and are likely to increase over
time. The Projections should therefore not be regarded as a representation by
the Debtors or any other person that the results set forth in the Projections
will be achieved. In light of the foregoing, readers are cautioned not to place
undue reliance on the Projections. The Projections should be read together with
the information in Article VII of the Disclosure Statement entitled "Certain
Factors to be Considered", which sets forth important factors that could cause
actual results to differ from those in the Projections.

         PSC is subject to the informational requirements of the Securities
Exchange Act of 1934, as amended, and in accordance therewith files periodic
reports and other information with the SEC relating to its business, financial
statements and other matters. Such filings will not include projected financial
information. The Debtors do not intend to update or otherwise revise the
Projections, including any revisions to reflect events or circumstances existing
or arising after the date of this Disclosure Statement or to reflect the
occurrence of unanticipated events, even if any or all of the underlying
assumptions do not come to fruition. Furthermore, the Debtors do not intend to
update or revise the Projections to reflect changes in general economic or
industry conditions.

                                       105

<PAGE>   116

         SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM
ACT OF 1995: The Projections contain statements which constitute
"forward-looking statements" within the meaning of the Securities Act of 1933
and the Securities Exchange Act of 1934, as amended by the Private Securities
Litigation Reform Act of 1995. "Forward-looking statements" in the Projections
include the intent, belief or current expectations of the Debtors and members of
their management team with respect to the timing of, completion of and scope of
the current restructuring, reorganization plan, strategic business plan, bank
financing, and debt and equity market conditions and the Debtors' future
liquidity, as well as the assumptions upon which such statements are based.
While the Debtors believe that the expectations are based on reasonable
assumptions within the bounds of their knowledge of their business and
operations, parties in interest are cautioned that any such forward-looking
statements are not guarantees of future performance, and involve risks and
uncertainties, and that actual results may differ materially from those
contemplated by such forward-looking statements. Important factors currently
known to management that could cause actual results to differ materially from
those contemplated by the forward-looking statements in the Projections include,
but are not limited to, further adverse developments with respect to the
Debtors' liquidity position or operations of the Debtors' various businesses,
adverse developments in the Debtors' efforts to renegotiate their funding and
adverse developments in the bank financing or public or private markets for debt
or equity securities, or adverse developments in the timing or results of the
Debtors' strategic business plan (including the time line to emerge from Chapter
11), the difficulty in controlling industry costs and integrating new
operations, the ability of the Debtors to realize the anticipated general and
administrative expense savings and overhead reductions presently contemplated,
the ability of the Debtors to return the Debtors' operations to profitability,
the level and nature of any restructuring and other one-time charges, the
difficulty in estimating costs relating to exiting certain markets and
consolidating and closing certain operations, and the possible negative effects
of a change in applicable legislation.

B.       ACCEPTANCE OF THE PLAN

         As a condition to confirmation, the Bankruptcy Code requires that each
Class of Impaired Claims vote to accept the Plan, except under certain
circumstances.

         Section 1126(c) of the Bankruptcy Code defines acceptance of a plan by
a class of impaired claims as acceptance by holders of at least two-thirds (2/3)
in dollar amount and more than one-half (1/2) in number of claims in that class,
but for that purpose counts only those who actually vote to accept or to reject
the Plan. Thus, Class 6 and 7 will have voted to accept the Plan only if
two-thirds (2/3) in amount and a majority in number actually voting in each
Class cast their Ballots in favor of acceptance. Holders of Claims who fail to
vote are not counted as either accepting or rejecting a plan.

C.       BEST INTERESTS TEST

         As noted above, even if a plan is accepted by the holders of each class
of claims and interests, the Bankruptcy Code requires a bankruptcy court to
determine that the plan is in the best interests of all holders of claims or
interests that are impaired by the plan and that have not accepted the plan. The
"best interests" test, as set forth in section 1129(a)(7) of the Bankruptcy
Code, requires a bankruptcy court to find either that all members of an impaired
class of claims or interests have accepted the plan or that the plan will
provide a member who has not accepted the plan with a recovery of property of a
value, as of the effective date of the plan, that is not less than the amount
that such holder would recover if the debtor were liquidated under Chapter 7 of
the Bankruptcy Code.

         To calculate the probable distribution to holders of each impaired
class of claims and interests if the Debtors were liquidated under Chapter 7, a
bankruptcy court must first determine the aggregate dollar amount that would be
generated from a debtor's assets if its Chapter 11 cases were converted to
Chapter 7 cases under the Bankruptcy Code. This "liquidation value" would
consist primarily of the proceeds from a forced sale of the debtor's assets by a
Chapter 7 trustee.

                                       106

<PAGE>   117

         The amount of liquidation value available to unsecured creditors would
be reduced by, first, the claims of secured creditors to the extent of the value
of their collateral, and, second, by the costs and expenses of liquidation, as
well as by other administrative expenses and costs of both the Chapter 7 cases
and the Chapter 11 cases. Costs of liquidation under Chapter 7 of the Bankruptcy
Code would include the compensation of a trustee, as well as of counsel and
other professionals retained by the trustee, asset disposition expenses, all
unpaid expenses incurred by the debtor in its Chapter 11 cases (such as
compensation of attorneys, financial advisors and accountants) that are allowed
in the Chapter 7 cases, litigation costs, and claims arising from the operations
of the debtor during the pendency of the Chapter 11 cases. The liquidation
itself would trigger certain priority payments that otherwise would be due in
the ordinary course of business. Those priority claims would be paid in full
from the liquidation proceeds before the balance would be made available to pay
general claims or to make any distribution in respect of equity interests. The
liquidation would also prompt the rejection of a large number of executory
contracts and unexpired leases and thereby create a significantly higher number
of unsecured creditors.

         Once the court ascertains the recoveries in liquidation of secured
creditors and priority claimants, it must determine the probable distribution to
general unsecured creditors and equity security holders from the remaining
available proceeds in liquidation. If such probable distribution has a value
greater than the distributions to be received by such creditors and equity
security holders under the plan, then the plan is not in the best interests of
creditors and equity security holders. Therefore, the Debtors believe that the
members of each Class of Impaired Claims and Interests will receive more under
the Plan than they would receive if the Debtors were liquidated.

D.       LIQUIDATION ANALYSIS

         The Debtors believe that the Plan meets the "best interests of
creditors" test of section 1129(a)(7) of the Bankruptcy Code. The Debtors
believe that the members of each Impaired Class will receive greater value under
the Plan than they would in a liquidation. The liquidation analysis (the
"Liquidation Analysis") for consolidated PSC, including the Debtors, the
Canadian Debtors and the non-filing Subsidiaries (collectively, "Consolidated
PSC") is annexed as Appendix E to this Disclosure Statement.

         The Liquidation Analysis presumes the liquidation of Consolidated PSC
under the law of the respective jurisdictions of incorporation/amalgamation for
each individual Subsidiary. The Liquidation Analysis relies on certain projected
future events and necessarily relies on certain estimates and assumptions in
order to arrive at a hypothetical liquidation value for Consolidated PSC.

         The Liquidation Analysis provides that in the event of a liquidation as
described therein, the proceeds available to satisfy Class 6 Secured Lender
Claims would be approximately $277.5 million, leaving a shortfall to
satisfaction of Lender Claims of approximately $726.3 million. The Liquidation
Analysis provides that no distribution would be available to holders of Class 7
Impaired Unsecured Claims or holders of Class 8A Interests, Class 8B Claims or
Class 8C Claims. Therefore, because the Plan provides for distributions or
retention of interests for Classes 7, 8A, 8B and 8C, if Class 7 votes to accept
the Plan, such holders of Impaired Claims and Interests in such classes will
receive a greater recovery under the Plan than they would in a liquidation. The
Plan also meets the "best interests test" with respect to Lender Claims. In a
liquidation, the distributions on account of Lender Claims is shown in the
Liquidation Analysis to be significantly less than the value of distributions
provided under the Plan. Although the Debtors believe that the Plan meets the
"best interests test" of section 1129(a)(7) of the Bankruptcy Code, there can be
no assurance that the Bankruptcy Court will determine that the Plan meets this
test.

E.       VALUATION OF THE REORGANIZED DEBTORS

         In conjunction with formulating the Plan, the Debtors determined that
it was necessary to estimate a post-confirmation going concern enterprise value
for the Reorganized Debtors. Accordingly, the Debtors directed Ernst & Young
Corporate Finance Inc. ("EYCF") to prepare such a valuation. A summary of the
valuation prepared by EYCF is attached with Appendix G to the Disclosure
Statement.

                                       107

<PAGE>   118

         As shown in the valuation, EYCF has determined pursuant to various
well-accepted valuation techniques that the enterprise value of Reorganized PSC
and its Subsidiaries and affiliates is in a range of $500 million to $600
million. The mid-point range of this range of value is $550 million.

F.       APPLICATION OF THE "BEST INTERESTS" TEST TO THE LIQUIDATION ANALYSIS
         AND THE VALUATION OF THE REORGANIZED DEBTORS

         It is impossible to determine with any specificity the value each
creditor will receive as a percentage of its Allowed Claim. This difficulty in
estimating the value of such recoveries is due to, among other things, the
inherent uncertainty with respect to future performance and the question of a
public market for the New Common Shares or Reorganized PSI Common Shares, as the
case may be, New Secured PIK Debt, New Unsecured PIK Notes and New Unsecured
Convertible Notes. Such a valuation is made even more difficult because the
analysis regarding the amount of Class 7 Claims that will ultimately be Allowed
is preliminary and subject to change.

         After considering the effects that a Chapter 7 liquidation would have
on the ultimate proceeds available for the distribution to Creditors in the
Chapter 11 Cases versus the valuation of the of the Reorganized Debtors as a
going concern, each as set forth above, the Debtors have determined that the
confirmation of the Plan will provide each holder of an Allowed Class 6 Secured
Lender Claim and each holder of Allowed Class 7 Impaired Unsecured Claim with a
recovery that is not less than such holder would receive pursuant to a
liquidation under Chapter 7.

G.       CONFIRMATION WITHOUT ACCEPTANCE OF ALL IMPAIRED CLASSES: THE
         "CRAMDOWN" ALTERNATIVE

         In view of the deemed rejection by Class 9, the Debtors will seek
confirmation of the Plan pursuant to the "cramdown" provisions of the Bankruptcy
Code. Specifically, section 1129(b) of the Bankruptcy Code provides that a plan
can be confirmed even if the plan is not accepted by all impaired classes, as
long as at least one impaired class of claims has accepted it. The Bankruptcy
Court may confirm a plan at the request of the debtors if the plan "does not
discriminate unfairly" and is "fair and equitable" as to each impaired class
that has not accepted the plan. A plan does not discriminate unfairly within the
meaning of the Bankruptcy Code if a dissenting class is treated equally with
respect to other classes of equal rank.

         A plan is fair and equitable as to a class of secured claims that
rejects such plan if the plan provides (a)(i) that the holders of claims
included in the rejecting class retain the liens securing those claims whether
the property subject to those liens is retained by the debtor or transferred to
another entity, to the extent of the allowed amount of such claims, and (ii)
that each holder of a claim of such class receives on account of that claim
deferred cash payments totaling at least the allowed amount of that claim, of a
value, as of the effective date of the plan, of at least the value of the
holder's interest in the estate's interest in such property; (b) for the sale,
subject to section 363(k) of the Bankruptcy Code, of any property that is
subject to the liens securing the claims included in the rejecting class, free
and clear of the liens, with the liens to attach to the proceeds of the sale,
and the treatment of the liens on proceeds under clause (a) or (c) of this
paragraph; or (c) for the realization by such holders of the indubitable
equivalent of such claims.

         A plan is fair and equitable as to a class of unsecured claims which
rejects a plan if the plan provides (a) for each holder of a claim included in
the rejecting class to receive or retain on account of that claim property that
has a value, as of the effective date of the plan, equal to the allowed amount
of such claim; or (b) that the holder of any claim or interest that is junior to
the claims of such class will not receive or retain on account of such junior
claim or interest any property at all.

         A plan is fair and equitable as to a class of equity interests that
rejects a plan if the plan provides (a) that each holder of an interest included
in the rejecting class receive or retain on account of that interest property
that has a value, as of the effective date of the plan, equal to the greatest of
the allowed amount of any fixed liquidation preference to which such holder is
entitled, any fixed redemption price to which such holder is entitled, or the
value

                                       108

<PAGE>   119

of such interest; or (b) that the holder of any interest that is junior to
the interests of such class will not receive or retain under the plan on account
of such junior interest any property at all.

         The Debtors also will seek confirmation of the Plan pursuant to the
"cramdown" provisions of the Bankruptcy Code if the holders of Allowed Class 7
Claims vote to reject the Plan. Serious legal and factual questions have been
raised by certain parties in interest as to whether such a "cramdown" can be
accomplished under the Bankruptcy Code. The Debtors, the Lenders, the Creditors'
Committee and First Union as Indenture Trustee all disagree with this
contention.

                                  ARTICLE XII.

            ALTERNATIVES TO CONFIRMATION AND CONSUMMATION OF THE PLAN

         The Debtors believe that the Plan affords holders of Class 6 and 7
Claims the potential for the greatest realization on the Debtors' assets and,
therefore, is in the best interests of such holders. The Plan as presented is
the result of considerable negotiations between PSC and an ad hoc steering
committee of Lenders, as well as significant unsecured creditors.

         If, however, the requisite acceptances are not received, or the Plan is
not confirmed and consummated, the theoretical alternatives include: (a)
formulation of an alternative plan or plans of reorganization, or (b)
liquidation of the Debtors under Chapter 7 or 11 of the Bankruptcy Code.

A.       ALTERNATIVE PLAN(S) OF REORGANIZATION

         If the requisite acceptances are not received or if the Plan is not
confirmed, the Debtors (or, if the Debtors' exclusive periods in which to file
and solicit acceptances of a plan of reorganization have expired, any other
party-in-interest) could attempt to formulate and propose a different plan or
plans of reorganization. Such a plan or plan(s) might involve either a
reorganization and continuation of the Debtors' businesses or an orderly
liquidation of assets.

         Additionally, it is not clear whether the Debtors could survive as
going concerns in a protracted alternative plan of reorganization. They could
have difficulty sustaining operations in the face of high costs, erosion of
customer confidence, and liquidity difficulties that could well result if they
remained Debtors for any length of time.

         With respect to an alternative plan, the Debtors have explored various
other alternatives in connection with the extensive negotiation process involved
in the formulation and development of the Plan. The Debtors believe that the
Plan, as described herein, the result of extensive negotiations between the
Debtors and various creditor constituencies, enables creditors to realize the
greatest possible value under the circumstances, and, that as compared to any
alternative plan of reorganization, the Plan has the greatest chance to be
confirmed and consummated.

B.       LIQUIDATION UNDER CHAPTER 7 OR CHAPTER 11

         If no plan is confirmed, the Chapter 11 Cases may be converted to cases
under Chapter 7 of the Bankruptcy Code, pursuant to which a trustee would be
elected or appointed to liquidate the Debtors' assets for distribution to
Creditors in accordance with the priorities established by the Bankruptcy Code.
It is impossible to predict precisely how the proceeds of the liquidation would
be distributed to the respective holders of Claims against or Interests in the
Debtors.

         The Debtors believe that in a liquidation under Chapter 7, before
Creditors received any distribution, additional administrative expenses involved
in the appointment of a trustee or trustees and attorneys, accountants and other
professionals to assist such trustees would cause a substantial diminution in
the value of the Debtors'

                                       109

<PAGE>   120

Estates. The assets available for distribution to Creditors would be reduced by
such additional expenses and by Claims, some of which would be entitled to
priority, which would arise by reason of the liquidation and from the rejection
of leases and other executory contracts in connection with the cessation of
operations and the failure to realize the greater going concern value of the
Debtors' assets.

         The Debtors could also be liquidated pursuant to the provisions of a
Chapter 11 plan of reorganization. In a liquidation under Chapter 11, the
Debtors' assets could be sold in an orderly fashion over a more extended period
of time than in a liquidation under Chapter 7. Thus, a Chapter 11 liquidation
might result in larger recoveries than in a Chapter 7 liquidation, but the delay
in distributions could result in lower present values received and higher
administrative costs. Because a trustee is not required in a Chapter 11 case,
expenses for professional fees could be lower than in a Chapter 7 case, in which
a trustee must be appointed. Any distribution to the holders of Claims under a
Chapter 11 liquidation plan probably would be delayed substantially.

         Although preferable to a Chapter 7 liquidation, the Debtors believe
that any alternative liquidation under Chapter 11 is a much less attractive
alternative to creditors than the Plan because of the greater return the Debtors
anticipate is provided by the Plan.

                                  ARTICLE XIII.

                       THE SOLICITATION; VOTING PROCEDURE

A.       SOLICITATION OF VOTES

         This Disclosure Statement, including all Appendices hereto, together
with the related materials included herewith, is being furnished to the holders
of Class 6 and 7 Claims for the purposes of voting on the Plan. As a condition
to confirmation, the Bankruptcy Code requires that each Class of Impaired Claims
vote to accept the Plan, except under certain circumstances.

         The Debtors may alter, amend, or modify the Plan or any Exhibits
thereto under section 1127(a) of the Bankruptcy Code at any time prior to the
Confirmation Date, subject to the approval of the Required Lenders. After the
Confirmation Date and prior to substantial consummation of the Plan, as defined
in section 1101(2) of the Bankruptcy Code, the Reorganized Debtors may, under
section 1127(b) of the Bankruptcy Code, institute proceedings in the Bankruptcy
Court to remedy any defect or omission or reconcile any inconsistencies in the
Plan, the Disclosure Statement, or the Confirmation Order, and such matters as
may be necessary to carry out the purposes and effects of the Plan so long as
such proceedings do not materially adversely affect the treatment of holders of
Claims or Interests under the Plan; provided, however, that prior notice of such
proceedings shall be served in accordance with the Bankruptcy Rules or order of
the Bankruptcy Court.

B.       VOTING DEADLINE

         All votes to accept or reject the Plan must be cast by using the ballot
(the "Ballot") enclosed with this Disclosure Statement. No other votes will be
counted. Ballots must be RECEIVED by the Voting Agent no later than 5:00 p.m.
(Prevailing Eastern Time) on the Voting Deadline or if the date is extended as
set forth below, the period during which Ballots will be accepted will terminate
at 5:00 p.m. (Prevailing Eastern Time) on such extended date (in either case,
the "Voting Deadline").

         The Debtors reserve the absolute right to extend, by oral or written
notice to the Voting Agent, the period of time (on a daily basis, if necessary)
during which Ballots will be accepted for any reason including, but not limited
to, determining whether or not the Requisite Acceptances have been received, by
making a public announcement of such extension no later than 9:00 a.m.
(Prevailing Eastern Time) on the first Business Day next succeeding the
previously announced Voting Deadline. Without limiting the manner in which the
Debtors may choose to make any

                                       110

<PAGE>   121

public announcement, the Debtors will not have any obligation to publish,
advertise, or otherwise communicate any such public announcement, other than by
issuing a news release through the Dow Jones News Service. There can be no
assurance that the Debtors will exercise their right to extend the solicitation
period for the receipt of Ballots.

         Except to the extent requested by the Debtors or as permitted by the
Bankruptcy Court, Ballots received after the Voting Deadline will not be counted
or otherwise used in connection with the Debtors' request for confirmation of
the Plan (or any permitted modification thereof).

C.       VOTING PROCEDURES

         The failure of a Holder of Class 6 or 7 Claim to deliver a duly
executed Ballot will be deemed to constitute an abstention by such Lender with
respect to voting on the Plan and such abstentions will not be counted as votes
for or against the Plan.

         You should provide all of the information requested by the Ballots you
receive. You should complete and return all Ballots that you receive in the
return envelope provided with each such Ballot. IN NO CASE SHOULD A BALLOT BE
DELIVERED TO ANY ENTITY OTHER THAN THE VOTING AGENT.

D.       FIDUCIARIES AND OTHER REPRESENTATIVES

         If a Ballot is signed by a trustee, executor, administrator, guardian,
attorney-in-fact, officer of a corpora tion, or another acting in a fiduciary or
representative capacity, such person should indicate such capacity when signing
and, unless otherwise determined by the Debtors, must submit proper evidence
satisfactory to the Debtors of authority to so act. Authorized signatories
should submit the separate Ballot of each beneficial owner for whom they are
voting.

E.       PARTIES IN INTEREST ENTITLED TO VOTE

         Under section 1124 of the Bankruptcy Code, a class of claims or
interests is deemed to be "impaired" under a plan unless (i) the plan leaves
unaltered the legal, equitable, and contractual rights to which such claim or
interest entitles the holder thereof or (ii) notwithstanding any legal right to
an accelerated payment of such claim or interest, the plan cures all existing
defaults (other than defaults resulting from the occurrence of events of
bankruptcy) and reinstates the maturity of such claim or interest as it existed
before the default.

         In general, a holder of a claim or interest may vote to accept or to
reject a plan if (i) the claim or interest is "allowed," which means generally
that no party in interest has objected to such claim or interest, and (ii) the
claim or interest is impaired by the plan. If, however, the holder of an
impaired claim or interest will not receive or retain any distribution under the
plan on account of such claim or interest, the Bankruptcy Code deems such holder
to have rejected the plan, and, accordingly, holders of such claims and
interests do not actually vote on the plan. If a claim or interest is not
impaired by the plan, the Bankruptcy Code deems the holder of such claim or
interest to have accepted the plan and, accordingly, holders of such claims and
interests are not entitled to vote on the plan.

F.       CLASSES IMPAIRED UNDER THE PLAN

         Classes 6 and 7 are entitled to vote to accept or reject the Plan,
provided, however, that in the event the Alternate Canadian Transactions are
implemented, the Canadian Impaired Unsecured Claims that make the U.S. Plan
Election shall not be entitled to vote on the Plan. If the Class 8 Solicitation
Order is entered, Classes 8A, 8B and 8C will be deemed to have rejected the Plan
and therefore will not be entitled to vote. If the Class 8 Solicitation Order is
not entered, then Classes 8A, 8B and 8C will be entitled to vote to accept or
reject the Plan. By operation of law, each Unimpaired Class of Claims is deemed
to have accepted the Plan and, therefore, is not entitled to vote to accept

                                       111

<PAGE>   122

or the Plan. By operation of law, Class 9 is deemed to have rejected the
Plan and therefore is not entitled to vote to accept or reject the Plan.

G.       WAIVERS OF DEFECTS, IRREGULARITIES, ETC.

         Unless otherwise directed by the Bankruptcy Court, all questions as to
the validity, form, eligibility (including time of receipt), acceptance, and
revocation or withdrawal of Ballots will be determined by the Voting Agent and
the Debtors in their sole discretion, which determination will be final and
binding. As indicated below under "Withdrawal of Ballots; Revocation," effective
withdrawals of Ballots must be delivered to the Voting Agent prior to the Voting
Deadline. The Debtors reserve the absolute right to contest the validity of any
such withdrawal. The Debtors also reserve the right to reject any and all
Ballots not in proper form, the acceptance of which would, in the opinion of the
Debtors or their counsel, be unlawful. The Debtors further reserve the right to
waive any defects or irregularities or conditions of delivery as to any
particular Ballot. The interpretation (including the Ballot and the respective
instructions thereto) by the Debtors, unless otherwise directed by the
Bankruptcy Court, will be final and binding on all parties. Unless waived, any
defects or irregularities in connection with deliveries of Ballots must be cured
within such time as the Debtors (or the Bankruptcy Court) determine. Neither the
Debtors nor any other person will be under any duty to provide notification of
defects or irregularities with respect to deliveries of Ballots nor will any of
them incur any liabilities for failure to provide such notification. Unless
otherwise directed by the Bankruptcy Court, delivery of such Ballots will not be
deemed to have been made until such irregularities have been cured or waived.
Ballots previously furnished (and as to which any irregularities have not
theretofore been cured or waived) will be invalidated.

H.       WITHDRAWAL OF BALLOTS; REVOCATION

         Any party who has delivered a valid Ballot for the acceptance or
rejection of the Plan may withdraw such acceptance or rejection by delivering a
written notice of withdrawal to the Voting Agent at any time prior to the Voting
Deadline. A notice of withdrawal, to be valid, must (i) contain the description
of the Claim(s) to which it relates and the aggregate principal amount
represented by such Claim(s), (ii) be signed by the withdrawing party in the
same manner as the Ballot being withdrawn, (iii) contain a certification that
the withdrawing party owns the Claim(s) and possesses the right to withdraw the
vote sought to be withdrawn and (iv) be received by the Voting Agent in a timely
manner at the address set forth in Article XIII below. The Debtors intend to
consult with the Voting Agent to determine whether any withdrawals of Ballots
were received and whether the Requisite Acceptan ces of the Plan have been
received. As stated above, the Debtors expressly reserve the absolute right to
contest the validity of any such withdrawals of Ballots.

         Unless otherwise directed by the Bankruptcy Court, a purported notice
of withdrawal of Ballots which is not received in a timely manner by the Voting
Agent will not be effective to withdraw a previously cast Ballot.

         Any party who has previously submitted to the Voting Agent prior to the
Voting Deadline a properly completed Ballot may revoke such Ballot and change
his or its vote by submitting to the Voting Agent prior to the Voting Deadline a
subsequent properly completed Ballot for acceptance or rejection of the Plan. In
the case where more than one timely, properly completed Ballot is received, only
the Ballot which bears the latest date will be counted for purposes of
determining whether the Requisite Acceptances have been received.

                          RECOMMENDATION AND CONCLUSION

         For all of the reasons set forth in this Disclosure Statement, the
Debtors believe that confirmation and consummation of the Plan is preferable to
all other alternatives. Consequently, the Debtors, the Committee and the
Debenture Holders urge all holders of Class 6 and 7 Claims to vote to ACCEPT the
Plan, and to complete and return their ballots so that they will be RECEIVED by
the Voting Agent on or before 5:00 p.m. Prevailing Eastern Time on the Voting
Deadline.

                                  INTRODUCTION

         Philip Services (Delaware), Inc., a Delaware corporation ("PSI"),
Philip Services Corp., an Ontario corporation ("PSC"), and those entities listed
on Exhibit A hereto (the "Subsidiary Debtors") hereby propose the following
joint plan of reorganization (the "Plan") for the resolution of their
outstanding creditor Claims and equity Interests. The Debtors are the proponents
of this Plan within the meaning of section 1129 of the Bankruptcy Code. All
capitalized terms not defined in this Introduction have the meanings ascribed in
Article I of this Plan. Reference is made to the Disclosure Statement,
distributed contemporaneously herewith, for a discussion of the Debtors'
history, businesses, properties, results of operations, projections for future
operations, risk factors, a summary and analysis of the Plan, and certain
related matters, including the New Securities to be issued under the Plan.

         As explained in the Disclosure Statement, the precise treatment of
certain classes of Claims and Interests under the Plan differs depending on
which of two alternative restructurings are implemented in the Canadian CCAA
proceedings of PSC and the other Canadian Debtors: the Canadian Reorganization
Plan or the Alternate Canadian Transactions. If the Canadian Reorganization Plan
is sanctioned, PSC and the other Canadian Debtors will reorganize and PSC, as
reorganized, will emerge from chapter 11 and its CCAA proceedings as the
ultimate parent company of the Reorganized Debtors and the Canadian Debtors.
Alternatively, if the Alternate Canadian Transactions are implemented, the
reorganization of the Canadian Debtors will be accomplished through the transfer
of the businesses of the Canadian Debtors as going concerns to one or more
direct or indirect subsidiaries of Reorganized PSI, with certain claims and
causes of action and other assets being retained by PSC and the other Canadian
Debtors, subject to the Lenders' security interests and Reorganized PSI will
emerge from chapter 11 as the ultimate parent company of the Reorganized
Debtors. In addition, the precise treatment of certain classes of Claims and
Interests under the Plan may differ if the Debtors waive the condition to the
Effective Date of this Plan that either the Canadian Reorganization Plan has
been sanctioned or the Alternate Canadian Transactions have been implemented and
thus this Plan becomes effective before the outcome of the Canadian Debtors'
CCAA proceedings has been determined. The Debtors believe that there will not be
a material economic impact on the nature or value of the distributions to be
made under this Plan as a result of which of these alternatives are implemented.

         All holders of Claims and all holders of Interests are encouraged to
read this Plan and the Disclosure Statement in their entirety before voting to
accept or reject this Plan. Subject to certain restrictions and requirements set
forth in section 1127 of the Bankruptcy Code and Fed. R. Bankr. P. 3019 and
Article XI of this Plan, the Debtors reserve the right to alter, amend, modify,
revoke or withdraw this Plan prior to its substantial consummation.

Secured Term Debt and (D) (i) if Class 7 votes to accept the Plan, 5,967,052,592
shares of the New Common Shares which shall be ninety-one percent (91%) of the
PSC Common Shares issued and outstanding as of the Effective Date (which shall
equal 21,840,000 PSC Common Shares after giving effect to the Reverse Stock
Split), subject to Dilution or (ii) if Class 7 votes to reject the Plan,
22,800,000 shares of the PSC Common Shares which shall be ninety-five percent
(95%) of the PSC Common Shares issued and outstanding as of the Effective Date
plus an amount of PSC Common Shares equal to the aggregate number of New Common
Shares that would have been available for distribution to Class 7 had Class 7
voted to accept the Plan (based on the Debtors' estimate of the aggregate amount
of Allowed Class 7 Claims), subject to Dilution, and an amount of New Unsecured
PIK Notes equal to the amount that would have been distributed to Class 7 had
Class 7 voted to accept the Plan (based on the Debtors' estimate of the
aggregate amount of Allowed Class 7 Claims).

                  Each LC Lender will fund its pro rata share of the Unfunded LC
Claim (a) in Cash, or (b) by forgoing distributions that it would otherwise
receive in respect of a Claim in the amount of its pro rata share of the
Unfunded LC Claim. If the distributions that would otherwise be received by an
LC Lender are insufficient to fund its pro rata share of the Unfunded LC Claim,
such deficiency may be paid by forgoing distributions to the extent necessary by
any Lender that is an Affiliate of such LC Lender. Any such Cash paid or
distributions forgone shall be reallocated pro rata among the holders of Allowed
Class 6 Secured Lender Claims.

                  On the Effective Date, Reorganized PSC shall record such
holders of Allowed Class 6 Lender Claims as holders of record of such New Common

described in the immediately succeeding paragraph, each holder of an Allowed
Class 6 Secured Lender Claim, in full satisfaction, settlement, release and
discharge of and in exchange for such Allowed Class 6 Secured Lender Claim
against the Debtors other than PSC and in exchange for the assignment of its
right as a secured creditor to receive certain proceeds of the Alternate

Distribution Date its pro rata share of (A) the Net Asset Sale Proceeds Pool,
(B) the New Secured PIK Debt, (C) the New Senior Secured Term Debt and (D) (i)

Class 6 Additional Distribution or (ii) if Class 7 votes to reject the Plan, one
hundred percent (100%) which shall equal 24,000,000 shares of the Reorganized

Allowed Class 6 Secured Lender Claims shall retain such claims against PSC and
the other Canadian Debtors and security interests in assets of PSC and the other
Canadian Debtors retained and not transferred in connection with the Alternate
Canadian Transactions and such claims shall continue to be governed by the
Pre-Petition Credit Facility Agreements.

                  Each LC Lender will fund its pro rata share of the Unfunded LC
Claim (a) in Cash, or (b) by forgoing distributions that it would otherwise
receive in respect of a Claim in the amount of its pro rata share of the
Unfunded LC Claim. If the distributions that would otherwise be received by an
LC Lender are insufficient to fund its pro rata share of the Unfunded LC Claim,
such deficiency may be paid by forgoing distributions to the extent necessary by
any Lender that is an Affiliate of such LC Lender. Any such Cash paid or
distributions forgone shall be reallocated pro rata among the holders of Allowed
Class 6 Secured Lender Claims.

Sanctioned.

                    (i)  If the holders of Allowed Class 7 Claims vote to
accept the Plan then each holder of an Allowed Class 7 Claim shall receive in
full satisfaction, settlement, release and discharge of and in exchange for such
Allowed Class 7 Claim, its pro rata share of (a) subject to the Class 7
Election, $60 million of New Unsecured PIK Notes to be issued pursuant to
Article IV.C.1 of the Plan and (b) 327,860,033 New Common Shares which shall be
five percent (5%) of the PSC Common Shares issued and outstanding as of the
Effective Date, (which shall equal 1,200,000 PSC Common Shares after giving
effect to the Reverse Stock Split), subject to Dilution, in each case which
distribution shall be shared pro rata with the holders of allowed Canadian
Impaired Unsecured Claims under the Canadian Reorganization Plan. The holders of
Unsecured Lender Claims shall be deemed to have waived any and all distributions
to which they would be entitled under the Plan as holders of Unsecured Lender
Claims, including the benefits of any and all contractual subordination
provisions in respect of the Old Debentures and shall receive no distributions
on account of such Unsecured Lender Claims; or

                    (ii)  if the holders of Allowed Class 7 Claims vote to
reject the Plan, then the holders of such Claims shall not receive or retain any
property on account of such Claims.

               (b)         Treatment if the Alternate Canadian Transactions
Are Implemented.

                    (i)  If the holders of Allowed Class 7 Claims vote to

entitled under the Plan as holders of Unsecured Lender Claims, including the
benefits of any and all contractual subordination provisions in respect of the
Old Debentures and shall receive no distributions on account of such Unsecured
Lender Claims; provided, however, that the holders of the Allowed Unsecured
Lender Claims shall retain such Claims against PSC and the Subsidiaries other
than the Debtors in the assets retained and not transferred in connection with
the Alternate Canadian Transactions and such claims shall continue to be
governed by the Pre-Petition Credit Facility Agreement; or

                    (ii)  if the holders of Allowed Class 7 Claims vote to
reject the Plan, then the holders of such Claims shall not receive or retain any
property on account of such Claims.

                  Qualifying Class 7 Creditors shall have the right to make the
Class 7 Election if Class 7 votes to accept the Plan. The Class 7 Election shall
entitle Qualifying Class 7 Creditors to elect to forgo their pro rata
distribution of New Unsecured PIK Notes and instead receive New Unsecured
Convertible Notes. If Class 7 votes to accept the Plan, Qualifying Class 7
Creditors electing New Unsecured Convertible Notes shall receive, in exchange
for every $1.00 in face amount of New Unsecured PIK Notes that such Qualifying
Class 7 Creditor would have received under the Plan, $1.50 in face amount of New
Unsecured Convertible Notes. The aggregate of New Unsecured Convertible Notes
shall not exceed $18 million. Holders of Old Debentures that do not make an
affirmative Class 7 Election or that do not vote on the Plan shall be deemed to
have elected to receive the New Unsecured Convertible Notes. All other
Qualifying Class 7 Creditors that do not make an affirmative Class 7 Election or
that do not vote on the Plan shall be deemed to have elected to receive the New
Unsecured PIK Notes.

                  If Qualifying Class 7 Creditors elect to convert more than $12
million in aggregate face amount of New Unsecured PIK Notes into New Unsecured
Convertible Notes, then each Qualifying Class 7 Creditor shall be entitled to
its pro rata share of $18 million in face amount of New Unsecured Convertible
Notes (with such pro rata determination to include only Claims of the Qualifying
Class 7 Creditors electing or that have been deemed to have elected the New
Unsecured Convertible Notes), and such holders shall be deemed not to have made
the Class 7 Election with respect to the balance of their Class 7 Claims.

                  On the Effective Date, the Old Debentures, the Old Indenture
and any agreement with respect to Impaired Unsecured Claims shall be terminated
automatically without any further action by any party and shall no longer be of
any force or effect, except that, as between the Indenture Trustee and the
holders of the Old Debentures, provisions relating to any indemnification of the
Indenture Trustee by the holders of Old Debentures, any payment of the Indenture
Trustee's compensation, expenses (including, but no limited to, the Indenture
Trustee's professional fees and expenses), disbursements and advances, and for

issuance of New Common Shares shall be two percent (2.0%) of the PSC Common
Shares issued and outstanding as of the Effective Date (which shall equal
480,000 of the PSC Common Shares after giving effect to the Reverse Stock Split)
subject to Dilution or (b) if the Alternate Canadian Transactions are
implemented or the Canadian Plan Condition is waived, receive two percent (2.0%)
which shall equal 480,000 Reorganized PSI Common Shares as of the Effective
Date, subject to Dilution.

         Notwithstanding any provision contained herein to the contrary, if
Class 7 votes to reject the Plan, then the holders of Class 8A Interests shall
not receive or retain any property on account of such Interests. In such case,
the Reorganized Debtors will take all such corporate actions as are necessary or
required on and after the Effective Date to cancel such Interests.

         4.       Class 8B: Securities Claims in the Securities Actions

                  (a)             Treatment if the Canadian Reorganization
Plan Is Sanctioned.

                  On or as soon as reasonably practicable after the later of the
Distribution Date or the date such Class 8B Claim becomes an Allowed Class 8B
Claim, in full satisfaction, settlement, release and discharge and in exchange
for Class 8B Claims, each holder of an Allowed Class 8B Claim will receive its

of Claim, if any. Only if no objection to the Proof of Claim is filed within the
required time period, including any extensions granted by the Bankruptcy Court
or agreed to by the Debtors and the holder, or if the Bankruptcy Court enters an
order allowing such a claim as other than a subordinated claim, shall such claim
be deemed an Allowed Canadian Impaired Unsecured Claim that has filed the U.S.
Plan Election. In no event shall the holder of such Claim be a Qualifying Class
7 Creditor.

F.   DISTRIBUTIONS TO CERTAIN HOLDERS OF CANADIAN IMPAIRED UNSECURED
     CLAIMS AND CANADIAN CLASS 8B AND 8C HOLDERS

     Each holder of a Canadian Impaired Unsecured Claim and each Canadian Class
8B or 8C Holder may make the U.S. Plan Election, entitling such holder to
receive distributions as provided in this Article III.F if the Alternate
Canadian Transactions are implemented. If the Alternate Canadian Transactions
are implemented, any holder of an Allowed Canadian Impaired Unsecured Claim that
makes the U.S. Plan Election shall receive a distribution of New Unsecured PIK
Notes and Reorganized PSI Common Shares identical to that which a holder of an
Allowed Class 7 Claim of equal amount would be entitled. If the Alternate
Canadian Transactions are implemented, any Canadian Class 8B or 8C Holder that
make the U.S. Plan Election shall receive the distribution to which such holder
would be entitled pursuant to Article III.C.4 or III.C.5, as applicable, if such
holder's claim were a Class 8B or 8C Claim, respectively. Any distribution to
which a holder of a Canadian Impaired Unsecured Claim or a Canadian Class 8B or
8C Holder is entitled under this Article III.F is subject to the application of
the provisions of this Plan governing distributions generally and application of
the provisions of this Plan, the Bankruptcy Code and other laws of the United
States regarding the determination of allowance and priority of such claims.

     If the Alternate Canadian Transactions are implemented, the Lenders will
enforce remedies available to them against PSC and the other Canadian Debtors.
The proceeds paid on the transfer of the assets of PSC and the other Canadian
Debtors will be distributed pursuant to the priorities under Canadian law of the
claims against such assets. Canadian Impaired Unsecured Claims will not be
compromised pursuant to the Alternate Canadian Transactions, but it is expected
that no distributions will be made to the holders of such claims. The
distributions that would have been made available under the Canadian
Reorganization Plan, if the Canadian Reorganization Plan had been sanctioned,
for distribution to the holders of Canadian Impaired Unsecured Claims that do
not make the U.S. Plan Election, will instead comprise the Class 6 Additional
Distribution and be distributed to the holders of Class 6 Lender Claims pursuant
to Article III.C.1.

     Holders of Canadian Impaired Unsecured Claims entitled to receive a
distribution pursuant to this Article III.F shall not be entitled to vote on the
Plan.

G.   DISTRIBUTIONS TO CLASSES 6, 7, 8B AND 8C IF CANADIAN PLAN CONDITION IS
WAIVED

     If the Canadian Plan Condition is waived, distributions to holders of
Claims in Classes 6 and 7 shall initially be made pursuant to the provisions of
Articles III.C.1.(b) and III.C.2.(b), respectively. If the Canadian Plan
Condition is waived, an amount of New Unsecured PIK Notes and the amount of
Reorganized PSI Common Shares equivalent to the amount of New Common Shares that
would be distributed to the holders of Canadian Impaired Unsecured Claims under
the Canadian Reorganization Plan (assuming all such Claims will be allowed)
shall be held by the Disbursing Agent pending the implementation of the Canadian
Reorganization Plan or the Alternate Canadian Transactions. If the Canadian
Reorganization Plan is implemented, such securities shall be deposited into the
Disputed Distribution Reserve and shall be distributed to holders of Allowed
Class 7 Claims under this Plan and Allowed Canadian Impaired Unsecured Claims in
accordance with the Canadian Reorganization Plan. If the Alternate Canadian
Transactions are implemented, such securities shall be distributed pursuant to
Articles III.F and III.C.1.(b) respectively, subject to the provisions of the
Plan governing distributions generally. The time, nature and amount of
distributions to holders of Claims in Classes 8B and 8C and Canadian Class 8B
and 8C Holders that make the U.S. Plan Election shall be determined upon the
approval of the Canadian Reorganization Plan or the Alternate Canadian
Transactions, respectively.

H.   ACCRUAL OF POST-PETITION INTEREST

     Interest on and fees and expenses, if any, with respect to Allowed Class 2
Other Secured Claims, shall be paid when due under the contract, agreement, or
other instrument governing the terms and conditions of the obligation comprising
such Allowed Claim, together with any additional amounts required to be paid
with respect to Unimpaired Claims pursuant to section 1124 of the Bankruptcy
Code. Except as otherwise provided above, elsewhere in this Plan, or in an order
of the Bankruptcy Court, no holder of an Allowed Claim that is not an Other
Secured Claim shall be entitled to the accrual of post-petition interest or the
payment by the Debtors or Reorganized Debtors of post-petition interest on
account of such Claim for any purpose.

                                   ARTICLE IV.

                      MEANS FOR IMPLEMENTATION OF THE PLAN

A.   CONTINUED CORPORATE EXISTENCE

     Subject to the Restructuring Transactions, the Reorganized Debtors shall
continue to exist after the Effective Date as separate corporate entities, in
accordance with the applicable law in the respective jurisdictions in which they
are incorporated and pursuant to their respective certificates or articles of
incorporation and bylaws in effect prior to the Effective Date, except (i) to
the extent such certificates or articles of incorporation and bylaws are amended
by this Plan or (ii) if the Canadian Reorganization Plan is sanctioned,
Reorganized PSC, with the consent of the Required Lenders, continues under the
laws of the Province of New Brunswick, which continuance is hereby expressly
authorized by this Plan. Notwithstanding anything to the contrary in this Plan,
including Article IV.J hereof as to substantive consolidation, subject to the
Restructuring Transactions, the Unimpaired Claims of a particular Debtor or
Reorganized Debtor shall remain the obligations solely of such Debtor or
Reorganized Debtor and shall not become obligations of any other Debtor or
Reorganized Debtor by virtue of the Plan, the Chapter 11 Cases or otherwise.

B.   CORPORATE ACTION

     1.   Asset Transfer Pursuant to the Alternate Canadian Transactions

     On the Effective Date, if the Alternate Canadian Transactions are
implemented, PSC, the other Canadian Debtors and PSI shall take any and all
steps necessary on their part to implement the Alternate Canadian Transactions.
PSC, PSI and the Reorganized Debtors are expressly authorized to take any and
all steps necessary to implement the Alternate Canadian Transactions, including
without limitation, PSC obtaining approval of the Alternate Canadian
Transactions by the Canadian Bankruptcy Court, entering into any and all
agreements necessary on their part to effectuate the Alternate Canadian
Transactions, and directing the other Canadian Debtors to obtain approval of the
Alternate Canadian Transactions by the Canadian Bankruptcy Court and to enter
into any and all agreements necessary to effectuate the Alternate Canadian
Transactions. The automatic stay of section 362(a) of the Bankruptcy Code shall
be deemed lifted on the Effective Date so that the Alternate Canadian
Transactions may be effectuated and shall be deemed lifted on or prior to the
Effective Date to the extent necessary to permit any required notices to be
issued or proceedings to be taken which may be necessary prior to the Effective
Date so that the transfer of assets pursuant to the Alternate Canadian
Transactions on or after the Effective Date may be made in compliance with
applicable law.

     2.   Cancellation of Old Securities and Agreements

     On the Effective Date, except as otherwise provided for herein, (i) the Old
Debentures, Other Equity Securities, any other note, bond (with the exception of
surety bonds outstanding), indenture or other instrument or document evidencing
or creating any indebtedness or obligation of a Debtor (except as provided in
Article III.C.2.(c)), except such notes or other instruments evidencing
indebtedness or obligations of a Debtor that are Reinstated or amended and
restated under the Plan, shall be canceled, and (ii) the obligations of the
Debtors under any agreements, indentures or certificates of designations
governing the Old Debentures and Other Equity Securities and any other note,
bond, indenture or other instrument or document evidencing or creating any
indebtedness or obligation of a Debtor, except such notes or other instruments
evidencing indebtedness or obligations of a Debtor that are Reinstated or
amended and restated under the Plan, as the case may be, shall be discharged. As
of the Effective Date, all Old Common Shares that have been authorized to be
issued but that have not been issued shall be deemed cancelled and extinguished
without any further action of any party.

     3.   Certificate of Incorporation and Bylaws 4.

     The certificate or articles of incorporation and bylaws of each Debtor
shall be amended as necessary to satisfy the provisions of the Plan and the
Bankruptcy Code and shall include, among other things, pursuant to section
1123(a)(6) of the Bankruptcy Code, a provision prohibiting the issuance of
nonvoting equity securities, but only to the extent required by section
1123(a)(6) of the Bankruptcy Code.

<PAGE>   156

     4.   Restructuring Transactions

     On or after the Effective Date, the applicable Reorganized Debtors with the
consent of the Required Lenders (to the extent such actions are taken on the
Effective Date) may enter into such transactions and may take such actions as
may be necessary or appropriate to effect a corporate restructuring of their
respective businesses, to simplify otherwise the overall corporate structure of
the Reorganized Debtors, or to reincorporate certain of the Subsidiary Debtors
under the laws of jurisdictions other than the laws of which the applicable
Subsidiary Debtors are presently incorporated. Such restructuring is
contemplated to include one or more mergers, consolidations, restructures,
dispositions, liquidations, or dissolutions, as may be determined by the Debtors
or Reorganized Debtors to be necessary or appropriate (collectively, the
"Restructuring Transactions"). The actions to effect the Restructuring
Transactions may include: (i) the execution and delivery of appropriate
agreements or other documents of merger, consolidation, restructuring,
disposition, liquidation or dissolution containing terms that are consistent
with the terms of the Plan and that satisfy the applicable requirements of
applicable state law and such other terms to which the applicable entities may
agree; (ii) the execution and delivery of appropriate instruments of transfer,
assignment, assumption or delegation of any asset, property, right, liability,
duty or obligation on terms consistent with the terms of the Plan and having
such other terms to which the applicable entities may agree; (iii) the filing of
appropriate certificates or articles of merger, consolidation or dissolution
pursuant to applicable state law; and (iv) all other actions that the applicable
entities determine to be necessary or appropriate, including making filings or
recordings that may be required by applicable state law in connection with such
transactions. The Restructuring Transactions may include one or more mergers,
consolidations, restructurings, dispositions, liquidations or dissolutions, as
may be determined by the Reorganized Debtors to be necessary or appropriate to
result in substantially all of the respective assets, properties, rights,
liabilities, duties and obligations of certain of the Reorganized Debtors
vesting in one or more surviving, resulting, or acquiring corporations. In each
case in which the surviving, resulting or acquiring corporation in any such
transaction is a successor to a Reorganized Debtor, such surviving, resulting or
acquiring corporation will perform the obligations of the applicable Reorganized
Debtor pursuant to the Plan to pay or otherwise satisfy the Allowed Claims
against such Reorganized Debtor, except as provided in any contract, instrument
or other agreement or document effecting a disposition to such surviving,
resulting or acquiring corporation, which may provide that another Reorganized
Debtor will perform such obligations.

     5.   Shareholder Rights Plan

     On the Effective Date, Reorganized PSC (if the Canadian Reorganization Plan
is sanctioned) or Reorganized PSI (if the Alternate Canadian Transactions are
implemented or if the Canadian Plan Condition is waived) shall implement the
Shareholder Rights Plan.

     6.   Reverse Stock Split

     If the Canadian Reorganization Plan is sanctioned, and if Class 7 has voted
to accept the Plan, on the Effective Date Reorganized PSC shall take all steps
necessary to implement the Reverse Stock Split.

     7.   Shareholder Approval

     If the Canadian Reorganization Plan is sanctioned, on or immediately after
the Effective Date and the distribution of New Common Shares to the holders of
Allowed Class 6 Secured Lender Claims, Reorganized PSC shall hold a meeting of
its shareholders for the purposes of: (i) ratifying and approving the
Shareholder Rights Plan; (ii) electing the directors of Reorganized PSC set out
in the Plan Supplement; (iii) amending the articles of incorporation of
Reorganized PSC to allow for the implementation of the Reverse Stock Split; (iv)
authorizing the continuance of Reorganized PSC under the laws of New Brunswick;
and (v) if Class 7 votes to reject the Plan, canceling the Old Common Shares.

be issued pursuant to the Plan without further act or action under applicable
law, regulation, order or rule other than the application for and receipt of

Reorganized PSI (if the Alternate Canadian Transactions are implemented or if

American stock exchange.

     2.   New Senior Secured Debt

     On the Effective Date, Reorganized PSC and Reorganized PSI (if the Canadian

     The Debtors, together with the Subsidiaries, expect to enter into a
post-confirmation loan facility, the Exit Facility, in order to (a) refinance
amounts outstanding on the Effective Date under the DIP Facility, (b) make other
payments required to be made on the Effective Date or the Distribution Date, and
(c) provide the additional borrowing capacity required by the Reorganized
Debtors and the Subsidiaries following the Effective Date to maintain their
operations.

     5.   Tax Related Transactions

     Immediately prior to implementation of the Plan, each holder of a Claim
under the Pre-Petition Credit Agreement shall be deemed to have exchanged such
Claim for an undivided co-ownership interest in all of the Claims under the
Pre-Petition Credit Agreement in the same aggregate principal amount as the
Claim so exchanged.

D.   DIRECTORS AND OFFICERS

     Subject to the requirements of section 1129(a)(5) of the Bankruptcy Code,
the Debtors intend to announce prior to the Confirmation Date the identities of
the individuals proposed to serve as officers of the Reorganized Debtors and the
directors of Reorganized PSC (if the Canadian Reorganization Plan is sanctioned)
or Reorganized PSI (if the Alternate Canadian Transactions are implemented or
the Canadian Plan Condition is waived). To the extent possible, the identities
of such individuals will be announced by inclusion of a list of proposed
directors and/or officers in the Plan Supplement, which will be filed with the
Bankruptcy Court at least five (5) Business Days prior to the commencement of
the Confirmation Hearing. The new board of directors for Reorganized PSC (if the
Canadian Reorganization Plan is sanctioned) or Reorganized PSI (if the Alternate
Canadian Transactions are implemented or if the Canadian Plan Condition is
waived) will consist of nine (9) directors, who will be nominated by holders of
Lender Claims. The nominees of the holders of Lender Claims shall include two
(2) members of the existing PSC board of directors and will include two (2)
members nominated by




                                       25
<PAGE>   158

High River Limited Partnership ("High River") provided that High River and any
holders of Lender Claims acting in concert with it beneficially own at least
twenty-five percent (25%) of the Lender Claims. If one or both of the nominees
from the existing board is a nominee on that board of High River or persons
acting in concert with it, that person will be counted as a High River nominee
on the slate for the new board of directors. The boards of directors of the
Reorganized Debtors shall have the responsibility for the management, control,
and operation of the Reorganized Debtors on and after the Effective Date;
provided, however, (i) if the Alternate Canadian Transactions are implemented,
then PSC shall be governed pursuant to the terms of the Alternate Canadian
Transactions or as otherwise determined by the Canadian Bankruptcy Court and
(ii) if the Canadian Plan Condition is waived, PSC shall continue to be governed
in accordance with its existing bylaws and by its existing board of directors.

E.   REVESTING OF ASSETS; RELEASES OF LIENS

     The property of each Debtor's Estate, together with any property of each
Debtor that is not property of its Estate and that is not specifically disposed
of pursuant to the Plan, shall revest in the applicable Debtor on the Effective
Date. Thereafter, each Debtor may operate its business and may use, acquire and
dispose of property free of any restrictions of the Bankruptcy Code, the
Bankruptcy Rules and the Bankruptcy Court. As of the Effective Date, all
property of each Debtor shall be free and clear of all Liens, Claims and
Interests, except as specifically provided in the Plan or the Confirmation
Order. Without limiting the generality of the foregoing, each Debtor may,
without application to or approval by the Bankruptcy Court, pay fees that it
incurs after the Effective Date for professional fees and expenses.

     Notwithstanding anything to the contrary set forth in the foregoing
paragraph, if the Alternate Canadian Transactions are implemented then the
vesting of the property of PSC shall occur pursuant to the Alternate Canadian
Transactions and any order of the Canadian Bankruptcy Court or other applicable
Canadian Court.

F.   PRESERVATION OF RIGHTS OF ACTION

     Except as otherwise provided in this Plan (including this Article IV.F and
Article IV.I.1) or the Confirmation Order, or in any contract, instrument,
release, indenture or other agreement entered into in connection with the Plan,
in accordance with section 1123(b) of the Bankruptcy Code, the Reorganized
Debtors shall retain and may enforce, sue on, settle or compromise (or decline
to do any of the foregoing) all claims, rights or causes of action, suits and
proceedings, whether in law or in equity, whether known or unknown, that the
Debtors or the Estates may hold against any Person or entity. Each Debtor or its
successor(s) may pursue such retained claims, rights or causes of action, suits
or proceedings as appropriate, in accordance with the best interests of the
Reorganized Debtor or its successor(s) who hold such rights.

     Notwithstanding anything to the contrary in this Plan and without limiting
the right of PSC or any other Canadian Debtor in respect of any other claim, if
the Alternate Canadian Transactions are implemented, then any claim, rights or
causes of action, suits and proceedings, whether in law or in equity, whether
known or unknown, that PSC and/or the Canadian Debtors may hold against Deloitte
& Touche, Robert Waxman, Greg Madesker and/or Rik Barrese shall remain property
of such entities and shall remain subject to the Lenders' Claims to the extent
such claims have not been satisfied in full as a result of distributions
pursuant to the Plan.

G.   EFFECTUATING DOCUMENTS; FURTHER TRANSACTIONS

     The chairman of the board of directors, president, chief financial officer,
or any other appropriate officer of PSC, PSI or any applicable Debtor, as the
case may be, shall be authorized to execute, deliver, file, or record such
contracts, instruments, releases, indentures, and other agreements or documents,
and take such actions as may be necessary or appropriate to effectuate and
further evidence the terms and conditions of the Plan. The secretary or
assistant secretary of PSC, PSI or any applicable Debtor, as the case may be,
shall be authorized to certify or attest to any of the foregoing actions.

H.   EXEMPTION FROM CERTAIN TRANSFER TAXES

     Pursuant to section 1146(c) of the Bankruptcy Code, any transfers from a
Debtor to a Reorganized Debtor or any other Person or entity pursuant to the
Plan in the United States shall not be subject to any document recording tax,
stamp tax, conveyance fee, intangibles or similar tax, mortgage tax, stamp act,
real estate transfer tax, mortgage recording tax or other similar tax or
governmental assessment, and the Confirmation Order shall direct the appropriate
state or local governmental officials or agents to forgo the collection of any
such tax or governmental assessment and to accept for filing and recordation any
of the foregoing instruments or other documents without the payment of any such
tax or governmental assessment.

with any claim against Deloitte & Touche, Robert Waxman, Greg Madesker and/or
Rik Barrese arising out of or related to the same nucleus of operative facts
alleged as of the Petition Date in the Securities Actions, the Chazen Actions or
the Liff Actions, including, without limitation, providing information and
documents, attendance at meetings and interviews, assisting counsel, attendance
at discoveries, if required, assistance at pre-trial preparation and attendance
at trial, including as a witness, but subject in the case of any person who is
at the relevant time no longer a director, officer or employee of any of the
Reorganized Debtors, to reimbursement of that person's foregone income and
reasonable expenses, provided further, that nothing contained herein shall
affect the rights and obligations of the parties designated in clauses (iii),
(v), (vi), (ix) and (x) of this Article IV.I.2.(a) under the Priority and
Subordination Agreement, dated as of December 4, 1998, the Security Sharing
Agreement, dated as of November 30, 1998 and the Intercreditor Agreement, dated
as of June 25, 1999.

                  (b) Holders of Claims and Interests. As of the Effective
Date, to the fullest extent permitted under applicable law, in consideration for
the obligations of the Debtors and the Reorganized Debtors under the Plan and
the Cash, securities, contracts, instruments, releases and other agreements or
documents to be delivered in connection with the Plan, and the benefits provided
by the Lenders and the Account Intermediaries under the Plan, each present and
former holder of a Claim or Interest (other than the releasing parties
identified in Article IV.I.2(a) above or any individual, corporation or other
entity that was at any time formerly one of the foregoing releasing parties)
will be deemed to release forever, waive and discharge all claims, obligations,
suits, judgments, damages, demands, debts, rights, causes of action and
liabilities (other than the rights to enforce the Debtors' or the Reorganized
Debtors' obligations under the Plan and the securities, contracts, instruments,
releases and other agreements and documents delivered thereunder), whether
liquidated or unliquidated, fixed or contingent, matured or unmatured, known or
unknown, foreseen or unforeseen, then existing or thereafter arising, in law,
equity or otherwise that are based in whole or in part on any act, omission,
transaction, event or other occurrence taking place on or prior to the Effective
Date in any way relating to the Debtors or Subsidiaries, the parties released
pursuant to this Article IV.I.2(b), the Reorganized Debtors the Chapter 11
Cases, the Lender Lock-up Agreement or the Plan against (i) the Debtors, the
Subsidiaries and the Reorganized Debtors, (ii) the Lenders as of September 15,

the Pre-Petition Credit Agreement, any official committees appointed in the
Chapter 11 Cases, the DIP Agent, the DIP Co-Arrangers and the holders of DIP
Facility Claims as of September 15, 1999 or an entity that subsequently becomes

Security Agent, (iii) the Account Intermediaries, (iv) any individual,
corporation or other entity that was at any time formerly one of the foregoing
released parties identified in subclause (ii) of this Article IV.I.2(b) and (v)
the respective affiliates, current and former officers, directors, employees,
agents, shareholders and professionals of the entities listed in subclause (ii)
of this Article IV.I.2.(b) (excluding Deloitte & Touche and any insurance
brokers retained by the Debtors) acting in such capacity. Under the Plan,
holders of Claims (other than the Lenders) and Interests are not deemed to have
released any non-Debtor third party other than the Lenders and those parties
explicitly listed in subsections (ii), (iii), (iv) and (v) above.

                                       28

         3.  Injunction Related to Releases

         As further provided in Article XIV.F, the Confirmation Order will
enjoin the prosecution, whether directly, derivatively or otherwise, of any
claim, obligation, suit, judgment, damage, demand, debt, right, cause of action,
liability or interest released, discharged or terminated pursuant to the Plan.

         4.   Reinstatement of Certain Releases

         The revocation of any release of any director, officer or employee
pursuant to Articles IV.I.1 or 2(a) hereof shall be void ab initio to the extent
that a court of competent jurisdiction, including, but not limited to the
Bankruptcy Court, determines that such director, officer or employee has
provided the factual information reasonably requested by the Reorganized Debtors
if the Canadian Reorganization Plan is sanctioned or by the Administrative Agent
or its successor if the Alternate Canadian Transactions are implemented.

J.       SUBSTANTIVE CONSOLIDATION FOR PURPOSES OF TREATING IMPAIRED CLAIMS

         The Plan is premised upon the substantive consolidation of the Debtors
only for purposes of treating Class 6, 7 or 8 Claims under the Plan, including
for voting, confirmation and distribution purposes. The Plan does not
contemplate the substantive consolidation of the Debtors with respect to the
other Classes of Claims or Interests set forth in the Plan. On the Effective
Date, (a) all guaranties of any Debtor of the payment, performance or collection
of another Debtor with respect to Class 6, 7 or 8 Claims shall be deemed
eliminated and cancelled; (b) any obligation of any Debtor and all guaranties
with respect to Class 6, 7 or 8 Claims thereof executed by one or more of the
other Debtors shall be treated as a single obligation and any obligation of two
or more Debtors, and all multiple Impaired Claims against such entities on
account of such joint obligations, shall be treated and Allowed only as a single
Impaired Claim against the consolidated Debtors; and (c) each Class 6, 7 or 8
Claim filed in the Chapter 11 Cases of any Debtor shall be deemed filed against
the consolidated Debtors and shall be deemed one Class 6, 7 or 8 Claim against
and obligation of the consolidated Debtors. Except as set forth in this Article
IV.J, such substantive consolidation shall not (other than for purposes related
to the Plan) (a) affect the legal and corporate structures of the Reorganized
Debtors, subject to the right of the Debtors or Reorganized Debtors to effect
the Restructuring Transactions as provided in Article IV.B.3 hereof, (b) cause
any Debtor to be liable for any Impaired Claim or Unimpaired Claim under the
Plan, for which it otherwise is not liable, and the liability of any Debtor for
any such Claim shall not be affected by such substantive consolidation, (c)
affect Intercompany Claims of Debtors against Debtors, and (d) affect Interests
in the Subsidiary Debtors. On the Effective Date, the Intercompany Claims of
Debtors against Debtors shall be Reinstated or discharged and satisfied, at the
option of the Reorganized Debtors with the consent of the Required Lenders,
by contributions, distributions or otherwise as determined by the Reorganized
Debtors. On the Effective Date, to the extent a Subsidiary Debtor is not
dissolved or merged as part of the Restructuring Transactions or except as
otherwise expressly provided for in the Plan, the Interests in such Subsidiary
Debtor shall remain outstanding.

K.       CONTRIBUTION AND INDEMNITY CLAIMS OTHER THAN ASSUMED INDEMNIFICATION
         OBLIGATIONS

         Any Claim other than the Assumed Indemnification Obligations against
any Debtor for reimbursement, contribution, indemnity or setoff that is subject
to section 510(b) and/or 510(c) of the Bankruptcy Code or related to or arising
from the facts surrounding, allegations or actions resulting in a Claim that is
subject to section 510(b) and/or 510(c) of the Bankruptcy Code or arising out of
such facts or alleged facts, and any Excluded Indemnification Obligation, shall
be deemed rejected for all purposes under the Plan and shall be deemed
disallowed under the Plan upon entry of the Confirmation Order pursuant to
section 502(e)(1)(B) of the Bankruptcy Code to the fullest extent permitted by
law; provided, however, to the extent that any such Claim is not so disallowed
and becomes an Allowed Claim against any Debtor, then such Allowed Claim shall
be treated as an Allowed Class 8C Claim pursuant to sections 510(b) and/or
510(c) of the Bankruptcy Code.

L.       ASSUMED INDEMNIFICATION OBLIGATIONS

         The Assumed Indemnification Obligations shall be deemed assumed by the
Reorganized Debtors as of the Effective Date without any further action by any
party and in the event the Alternate Canadian Transactions are implemented or
the Canadian Plan Condition is waived, the Assumed Indemnification Obligations
of PSC shall be deemed assumed by Reorganized PSI.

                                   ARTICLE V.

                       ACCEPTANCE OR REJECTION OF THE PLAN

A.       CLASSES ENTITLED TO VOTE

         Classes 6 and 7 are entitled to vote to accept or reject the Plan. If
the Class 8 Solicitation Order is entered, Classes 8A, 8B and 8C will be deemed
to have rejected the Plan and therefore will not be entitled to vote. If the
Class 8 Solicitation Order is not entered, then Classes 8A, 8B and 8C will be
entitled to vote to accept or reject the Plan. By operation of law, each
Unimpaired Class of Claims is deemed to have accepted the Plan and, therefore,
is not entitled to vote to accept or reject the Plan. By operation of law, Class
9 is deemed to have rejected the Plan and therefore is not entitled to vote to
accept or reject the Plan.

B.       ACCEPTANCE BY IMPAIRED CLASSES

         An Impaired Class of Claims shall have accepted the Plan if (i) the
holders (other than any holder designated under section 1126(e) of the
Bankruptcy Code) of at least two-thirds in amount of the Allowed Claims actually
voting in such Class have voted to accept the Plan and (ii) the holders (other
than any holder designated under section 1126(e) of the Bankruptcy Code) of more
than one-half in number of the Allowed Claims actually voting in such Class have
voted to accept the Plan. An Impaired Class of Interests shall have accepted the
Plan if the holders (other than any holder designated under section 1126(e) of
the Bankruptcy Code) of at least two-thirds in amount of the Allowed Interests
actually voting in such Class have voted to accept the Plan.

C.       CRAMDOWN

         The Debtors will seek confirmation of the Plan under section 1129(b) of
the Bankruptcy Code in view of the deemed rejection by Class 9. Subject to
Article XI hereof, the Debtors reserve the right to modify the Plan to the
extent, if any, that Confirmation pursuant to section 1129(b) of the Bankruptcy
Code requires modification.


                                   ARTICLE VI.

               SECURITIES TO BE ISSUED IN CONNECTION WITH THE PLAN

         On the Effective Date, Reorganized PSC and Reorganized PSI (if the
Canadian Reorganization Plan is sanctioned) or Reorganized PSI (if the Alternate
Canadian Transactions are implemented or if the Canadian Plan Condition is
waived) shall issue for distribution in accordance with the provisions of the
Plan all of the New Secured PIK Debt, New Unsecured PIK Notes, New Unsecured
Convertible Notes and New Common Shares (if the Canadian Reorganization Plan is
sanctioned) or Reorganized PSI Common Shares (if the Alternate Canadian
Transactions are implemented or if the Canadian Plan Condition is waived),
pursuant to the provisions of the Plan. All securities to be issued will be
deemed issued as of the Effective Date regardless of the date on which they are
actually distributed. The form of the Amended and Restated Credit Agreement
governing the New Secured PIK Debt shall be in substantially the form attached
in the Plan Supplement. The form of indenture governing the New Unsecured PIK
Notes shall be in substantially the form attached to the Plan Supplement. The
form of the New Convertible Notes Indenture governing the New Unsecured
Convertible Notes shall be substantially in the form attached to the Plan
Supplement.


                                  ARTICLE VII.

                       PROVISIONS GOVERNING DISTRIBUTIONS

A.       DISTRIBUTIONS FOR CLAIMS ALLOWED AS OF THE EFFECTIVE DATE

         Except as otherwise provided herein or as ordered by the Bankruptcy
Court, distributions to be made on account of Claims that are Allowed Claims as
of the Effective Date shall be made not later than the Distribution Date.
Distributions on account of Claims that first become Allowed Claims after the
Effective Date shall be made pursuant to Articles III, VII and IX of this Plan.
Notwithstanding the date on which any distribution of securities is actually
made to a holder of a Claim or


                                       30
<PAGE>   163

Interest that is an Allowed Claim or Allowed Interest on the Effective Date, as
of the date of the distribution such holder shall be deemed to have the rights
of a holder of such securities distributed as of the Effective Date.

B.       INTEREST ON CLAIMS

         Unless otherwise specifically provided for in this Plan or the
Confirmation Order, or required by applicable bankruptcy law, post-petition
interest shall not accrue or be paid on Claims, and no holder of a Claim shall
be entitled to interest accruing on or after the Petition Date on any Claim.
Interest shall not accrue or be paid upon any Disputed Claim in respect of the
period from the Petition Date to the date a final distribution is made thereon
if and after such Disputed Claim becomes an Allowed Claim.

C.       DISTRIBUTIONS BY DISBURSING AGENT AND THE INDENTURE TRUSTEE

         The Disbursing Agent shall make all distributions required under this
Plan (subject to the provisions of Articles III, VII and IX hereof).
Distributions provided for in the Plan on account of Allowed Old Debenture
Claims shall be made to the Indenture Trustee, as Disbursing Agent for Old
Debenture Claims, for further distribution to holders of Allowed Old Debenture
Claims. Any such further distributions shall be made pursuant to the Old
Indenture and the Plan, particularly to the Indenture Trustee (i) to itself as
Indenture Trustee for application of any unpaid fees, compensation, expenses
(including the Indenture Trustee's professional fees and expenses) disbursements
and advances; (ii) to itself as escrow agent holding an expense fund of
approximately $92,000 (such amount determined exclusively by the Indenture
Trustee) for the Great Plains Action, and thereafter (iii) on account of Allowed
Claims of holders of Old Debentures.

         If the Disbursing Agent is an independent third party designated by the
Reorganized Debtors to serve in such capacity, such Disbursing Agent shall
receive, without further Bankruptcy Court approval, reasonable compensation for
distribution services rendered pursuant to the Plan and reimbursement of
reasonable out-of-pocket expenses incurred in connection with such services from
the Reorganized Debtors on terms acceptable to the Reorganized Debtors. No
Disbursing Agent shall be required to give any bond or surety or other security
for the performance of its duties unless otherwise ordered by the Bankruptcy
Court.

D.       RECORD DATE FOR DISTRIBUTIONS TO HOLDERS OF LENDER CLAIMS AND OLD
         DEBENTURES

         At the close of business on the Distribution Record Date, the transfer
records for the Old Debentures and Lender Claims shall be closed, and there
shall be no further changes in the record holders of the Old Debentures or
Lender Claims. The Reorganized Debtors, the Disbursing Agent, and the
Administrative Agent for the Lenders shall have no obligation to recognize any
transfer of such Old Debentures or Lender Claims occurring after the
Distribution Record Date and shall be entitled instead to recognize and deal for
all purposes hereunder with only those record holders as of the close of
business on the Distribution Record Date.

E.       MEANS OF CASH PAYMENT

         Cash payments made pursuant to this Plan shall be in U.S. funds for
creditors located in the United States and in Canadian funds for creditors
located in Canada, unless such creditors in Canada have previously agreed, or
contracted for, payment in U.S. funds, by the means agreed to by the payor and
the payee, including by check or wire transfer or, in the absence of an
agreement, such commercially reasonable manner as the payor shall determine in
its sole discretion.

F.       CALCULATION OF DISTRIBUTION AMOUNTS

         1.  New Common Shares

         No fractional shares of New Common Shares or Reorganized PSI Common
Shares shall be issued or distributed under the Plan. Each Person entitled to
receive New Common Shares will receive the total number of whole shares of New
Common Shares or Reorganized PSI Common Shares to which such Person is entitled.
Whenever any distribution to a particular Person would otherwise call for
distribution of a fraction of a share of New Common Shares or Reorganized PSI
Common Shares, the actual distribution of shares of such stock shall be rounded
to the next higher or lower whole number as follows: (a) fractions 1/2 or
greater shall be rounded to the next higher whole number, and (b) fractions of
less than 1/2 shall be rounded to the next lower whole number. The total number
of shares of New Common Shares to be distributed to a Class of Claims or
Interests shall be adjusted as necessary to account for the rounding provided
for in this Article VII.F. No consideration shall be provided in lieu of
fractional shares that are rounded down.

                                       31
<PAGE>   164

         2.  New Debt Securities

         New Debt Securities will be issued in denominations of $1,000 and such
fractions thereof as is necessary.

         3.  Conversion Rate

         Canadian dollar ("CDN") Claims will be converted to United States
dollars for purposes of distributions by applying the June 25, 1999 Dow Jones
Canadian to United States exchange rate of .68254855.

G.       DELIVERY OF DISTRIBUTIONS

         Distributions to holders of Allowed Claims shall be made by the
Disbursing Agent (a) at the addresses set forth on the proofs of Claim filed by
such holders (or at the last known addresses of such holders if no Proof of
Claim is filed or if the Debtors have been notified of a change of address), (b)
at the addresses set forth in any written notices of address changes delivered
to the Disbursing Agent after the date of any related Proof of Claim, (c) at the
addresses reflected in the Schedules if no Proof of Claim has been filed and the
Disbursing Agent has not received a written notice of a change of address, (d)
in the case of the holder of an Allowed Old Debenture Claim, at the addresses
contained in the official records of the indenture trustee under the Old
Indenture, or (e) at the addresses set forth in a properly completed letter of
transmittal accompanying securities properly remitted to the Debtors. If any
holder's distribution is returned as undeliverable, no further distributions to
such holder shall be made unless and until the Disbursing Agent is notified of
such holder's then current address, at which time all missed distributions shall
be made to such holder without interest. No undeliverable distributions will go
back to the Reorganized Debtors. All claims for undeliverable distributions in
respect of Allowed Class 7 Claims (or Canadian Impaired Unsecured Claims for
which the U.S. Plan Election is made if the Alternate Canadian Transactions are
implemented) must be made on or before the expiration of the eighteenth (18th)
month following the Effective Date, after which date all unclaimed property
shall be distributed pro rata to the holders of the other Allowed Class 7 Claims
(and Canadian Impaired Unsecured Claims for which the U.S. Plan Election is made
if the Alternate Canadian Transactions are implemented) and the claim of any
holder or successor to such holder with respect to such property shall be
discharged and forever barred, notwithstanding any federal or state escheat laws
to the contrary. Nothing contained in the Plan shall require the Debtors,
Reorganized Debtors, any Disbursing Agent or the indenture trustee to attempt to
locate any holder of an Allowed Claim or Allowed Interest. All distributions
pursuant to the Plan shall be at the Reorganized Debtors' expense.

H.       SURRENDER OF SECURITIES AND INSTRUMENTS

         1.  Notes and Old Debentures

         Except as provided in Article VII.H.2 for lost, stolen, mutilated or
destroyed Old Debentures, each holder of an Allowed Claim evidenced by a note or
Old Debenture shall tender such note or Old Debenture to the Disbursing Agent in
accordance with written instructions to be provided in a letter of transmittal
to such holders by the Disbursing Agent as promptly as practicable following the
Effective Date. Such letter of transmittal shall specify that delivery of such
notes or Old Debentures will be effected, and risk of loss and title thereto
will pass, only upon the proper delivery of such notes or Old Debentures with
the letter of transmittal in accordance with such instructions. Such letter of
transmittal shall also include, among other provisions, customary provisions
with respect to the authority of the holder of the applicable note or Old
Debenture to act and the authenticity of any signatures required on the letter
of transmittal. All surrendered notes and Old Debentures shall be marked as
canceled and delivered to the Reorganized Debtors.

         2.  Lost, Mutilated or Destroyed Notes or Old Debentures

         In addition to any requirements under the applicable certificate or
articles of incorporation or bylaws of the applicable Debtor, any holder of a
Claim or an Interest evidenced by a note or Old Debenture that has been lost,
stolen, mutilated or destroyed shall, in lieu of surrendering such note or Old
Debenture, deliver to the Disbursing Agent (a) evidence satisfactory to the
Disbursing Agent of the loss, theft, mutilation or destruction; and (b) such
indemnity as may be required by the Disbursing Agent to hold the Disbursing
Agent harmless from any damages, liabilities or costs incurred in treating such
individual as a holder of a note or Old Debenture. Upon compliance with this
Article VII.H.2 by a holder of a Claim or an Interest evidenced by a note or Old
Debenture, such holder shall, for all purposes under the Plan, be deemed to have
surrendered a note or Old Debenture, as applicable.

                                       32
<PAGE>   165

         3.  Failure to Surrender Canceled Note or Old Debentures

         Any note or Old Debenture holder that fails to surrender or be deemed
to have surrendered such note or Old Debenture within the second anniversary
after the Effective Date shall have its claim for a distribution pursuant to the
Plan on account of such note or Old Debenture discharged and shall be forever
barred from asserting any such claim against any Reorganized Debtor or its
respective property.

I.       WITHHOLDING AND REPORTING REQUIREMENTS

         In connection with this Plan and all distributions hereunder, the
Disbursing Agent shall, to the extent applicable, comply with all tax
withholding and reporting requirements imposed by any federal, state,
provincial, local or foreign taxing authority, and all distributions hereunder
shall be subject to any such withholding and reporting requirements. The
Disbursing Agent shall be authorized to take any and all actions that may be
necessary or appropriate to comply with such withholding and reporting
requirements. Notwithstanding any other provision of the Plan (i) each holder of
an Allowed Claim or Interest that is to receive a distribution of New Securities
pursuant to the Plan shall have sole and exclusive responsibility for the
satisfaction and payment of any tax obligations imposed by any governmental
unit, including income, withholding and other tax obligations, on account of
such distribution, and (ii) no distribution shall be made to or on behalf of
such holder pursuant to the Plan unless and until such holder has made
arrangements satisfactory to the Disbursing Agent for the payment and
satisfaction of such tax obligations. Any New Securities to be distributed
pursuant to the Plan shall, pending the implementation of such arrangements, be
treated as an undeliverable distribution pursuant to Article VII.G. It is the
Debtors' intent that distributions under the Plan to holders of Claims are in
respect of, and to be applied to principal first and then interest.

J.       SETOFFS

         The Reorganized Debtors may, but shall not be required to, set off
against any Claim (or Canadian Impaired Unsecured Claim the holder of which has
made the U.S. Plan Election if the Alternate Canadian Transactions are
implemented), and the payments or other distributions to be made pursuant to the
Plan in respect of such Claim, claims of any nature whatsoever that the Debtors
or Reorganized Debtors may have against the holder of such Claim (or Canadian
Impaired Unsecured Claim the holder of which has made the U.S. Plan Election if
the Alternate Canadian Transactions are implemented); provided, however, that
neither the failure to do so nor the allowance of any Claim (or Canadian
Impaired Unsecured Claim the holder of which has made the U.S. Plan Election if
the Alternate Canadian Transactions are implemented) hereunder shall constitute
a waiver or release by the Reorganized Debtors of any such claim that the
Debtors or Reorganized Debtors may have against such holder. Notwithstanding
anything to the contrary, the Debtors and Reorganized Debtors will not exercise
any right of setoff against any Lender, any agents under the Pre-Petition Credit
Agreement or the DIP Facility Agreement, the Account Intermediaries or the DIP
Lenders.


                                  ARTICLE VIII.

                        TREATMENT OF EXECUTORY CONTRACTS
                              AND UNEXPIRED LEASES

A.       ASSUMED CONTRACTS AND LEASES

         Except as otherwise provided in the Plan, or in any contract,
instrument, release, indenture or other agreement or document entered into in
connection with the Plan, as of the Effective Date each Debtor shall be deemed
to have assumed each executory contract and unexpired lease to which it is a
party, unless such contract or lease (i) was previously assumed or rejected by
such Debtor, (ii) previously expired or terminated pursuant to its own terms, or
(iii) is otherwise set forth in the schedule to be filed in the Plan Supplement
as being an executory contract or unexpired lease to be rejected, provided,
however, that the Debtors reserve their right, at any time prior to the
Confirmation Date, to amend the schedule to be filed in the Plan Supplement to
delete any unexpired lease or executory contract therefrom or add any unexpired
lease or executory contract thereto. The Confirmation Order shall constitute an
order of the Bankruptcy Court under section 365 of the Bankruptcy Code approving
the contract and lease assumptions described above, as of the Effective Date.

         Each executory contract and unexpired lease that is assumed and relates
to the use, ability to acquire or occupancy of real property shall include (a)
all modifications, amendments, supplements, restatements or other agreements
made directly or


                                       33
<PAGE>   166

indirectly by any agreement, instrument or other document that in any manner
affect such executory contract or unexpired lease and (b) all executory
contracts or unexpired leases appurtenant to the premises, including all
easements, licenses, permits, rights, privileges, immunities, options, rights of
first refusal, powers, uses, usufructs, reciprocal easement agreements, vaults,
tunnel or bridge agreements or franchises, and any other interests in real
estate or rights in rem related to such premises, unless any of the foregoing
agreements has been rejected pursuant to an order of the Bankruptcy Court.

B.       PAYMENTS RELATED TO ASSUMPTION OF CONTRACTS AND LEASES

         Any monetary amounts by which each executory contract and unexpired
lease to be assumed pursuant to the Plan is in default shall be satisfied, under
section 365(b)(1) of the Bankruptcy Code, at the option of the Debtor party to
the contract or lease or the assignee of such Debtor party assuming such
contract or lease, by Cure. If there is a dispute regarding (i) the nature or
amount of any Cure, (ii) the ability of any Reorganized Debtor or any assignee
to provide "adequate assurance of future performance" (within the meaning of
section 365 of the Bankruptcy Code) under the contract or lease to be assumed,
or (iii) any other matter pertaining to assumption, Cure shall occur following
the entry of a Final Order resolving the dispute and approving the assumption or
assumption and assignment, as the case may be.

C.       REJECTED CONTRACTS AND LEASES

         Except as otherwise provided in the Plan and subject to Article VIII.A
hereof or as otherwise provided in any contract, instrument, release, indenture
or other agreement or document entered into in connection with the Plan, none of
the executory contracts and unexpired leases to which the Debtors, or any of
them, are a party shall be rejected under the Plan.

D.       COMPENSATION AND BENEFIT PROGRAMS

         Except and to the extent previously assumed or rejected by an order of
the Bankruptcy Court on or before the Confirmation Date, all employment
agreements and employee compensation and benefit programs of the Debtors,
including programs subject to sections 1114 and 1129(a)(13) of the Bankruptcy
Code, entered into before or after the Petition Date and not since terminated,
shall be deemed to be, and shall be treated as though they are, executory
contracts that are assumed under Article VIII.A of the Plan and in the event the
Alternate Canadian Transactions are implemented or the Canadian Plan Condition
is waived, assumed and assigned to PSI, except for (i) executory contracts or
plans specifically rejected pursuant to the Plan (to the extent such rejection
does not violate sections 1114 and 1129(a)(13) of the Bankruptcy Code) and (ii)
executory contracts or plans as have previously been rejected, are the subject
of a motion to reject, or have been specifically waived by the beneficiaries of
any plans or contracts; provided, however, that the Debtors' obligations, if
any, to pay all "retiree benefits" as defined in section 1114(a) of the
Bankruptcy Code shall continue.


                                   ARTICLE IX.

                       PROCEDURES FOR RESOLVING DISPUTED,
           CONTINGENT, AND UNLIQUIDATED CLAIMS AND DISPUTED INTERESTS

A.       PROSECUTION OF OBJECTIONS

         After the Confirmation Date, only the Debtors, the Reorganized Debtors
(subject to Article XIV.G), the Creditors' Committee and the Indenture Trustee
shall have the authority to file objections, settle, compromise, withdraw or
litigate to judgment objections to Claims (and Canadian Impaired Unsecured
Claims the holders of which have made the U.S. Plan Election if the Alternate
Canadian Transactions are implemented) and Interests. From and after the
Effective Date, the Reorganized Debtors may settle or compromise any Disputed
Class 7 Claim, Disputed Canadian Impaired Unsecured Claim the holder of which
has made the U.S. Plan Election if the Alternate Canadian Transactions are
implemented or Disputed Interest, without approval of the Bankruptcy Court.

B.       NO DISTRIBUTIONS PENDING ALLOWANCE

         Notwithstanding any other provision of the Plan, no payments or
distributions shall be made with respect to all or any portion of a Disputed
Class 7 Claim or Disputed Canadian Impaired Unsecured Claim unless and until
some portion thereof has become an Allowed Claim or Allowed Canadian Impaired
Unsecured Claim, respectively.

C.       DISPUTED DISTRIBUTION RESERVE; RESERVE FOR SUBSEQUENT DISTRIBUTIONS TO
         QUALIFYING CLASS 7 CREDITORS

         On the Effective Date (or as soon thereafter as is practicable) if
holders of Allowed Class 7 Claims are to receive distributions in accordance
with Article III.C, the Disbursing Agent shall establish the Disputed
Distribution Reserve by withholding from the initial distribution on account of
Allowed Class 7 Claims, Allowed Canadian Impaired Unsecured Claims and the Class
6 Additional Distribution (as applicable) an amount of New Unsecured PIK Notes
and New Common Shares (or Reorganized PSI Common Shares as applicable)
calculated as if all Class 7 Claims and Canadian Impaired Unsecured Claims were
Allowed Class 7 Claims and Allowed Canadian Impaired Unsecured Claims as of such
date, in an amount equal to one hundred percent (100%) of their Disputed Class 7
and Disputed Canadian Impaired Unsecured Claim Amount. The Disbursing Agent
shall also establish a reserve for subsequent distributions to Qualifying Class
7 Creditors containing the maximum amount of New Unsecured Convertible Notes
distributable under the Plan, if necessary, less the amount of New Unsecured
Convertible Notes distributed to Qualifying Class 7 Creditors on the
Distribution Date.

D.       DISTRIBUTIONS AFTER ALLOWANCE OF CLASS 7 CLAIMS AND CANADIAN IMPAIRED
         UNSECURED CLAIMS

         The Disbursing Agent shall make payments and distributions from the
Disputed Distribution Reserve to each holder of a Disputed Class 7 Claim that
has become an Allowed Class 7 Claim and each holder of a Disputed Canadian
Impaired Unsecured Claim that has become an Allowed Canadian Impaired Unsecured
Claim, in each case in accordance with the provisions of this Plan or the
Canadian Reorganization Plan, respectively. On the next succeeding interim
distribution date after the date that the order or judgment of the Bankruptcy
Court or the Canadian Bankruptcy Court allowing such Claim or claim becomes a
Final Order, the Disbursing Agent shall distribute to the holder of such Claim
or claim any New Unsecured PIK Notes and New Common Shares (or Reorganized PSI
Common Shares, as applicable) in the Disputed Distribution Reserve that would
have been distributed on the Distribution Date had such Claim been an Allowed
Class 7 Claim or an Allowed Canadian Impaired Unsecured Claim on the
Distribution Date. After a Final Order has been entered, or other final
resolution has been reached, with respect to each of the Disputed Class 7 Claims
and Disputed Canadian Impaired Unsecured Claims, any New Unsecured PIK Notes,
New Unsecured Convertible Notes, and New Common Shares or Reorganized PSI
Common Shares that remain in the Disputed Distribution Reserve and the reserve
for subsequent distributions to Qualifying Class 7 Creditors shall be
distributed, as applicable, pro rata to holders of (i) Allowed Claims in Class
7, (ii) Allowed Canadian Impaired Unsecured Claims and (iii) holders of the
Class 6 Secured Lender Claims on account of the Class 6 Additional Distribution,
if applicable (based on an estimate of the allowed Canadian Impaired Unsecured
Claims of holders who did not make the U.S. Plan Election); provided however,
that only Qualifying Class 7 Creditors shall be entitled to receive
distributions of New Unsecured Convertible Notes from the reserve for subsequent
distributions to Qualifying Class 7 Creditors. All distributions made under this
Article IX.D of the Plan on account of an Allowed Class 7 Claim and Allowed
Canadian Impaired Unsecured Claim, shall be made together with any payments or
other distributions made on account of, as well as any obligations arising from,
the distributed property, as if such Allowed Class 7 Claim or Allowed Canadian
Impaired Unsecured Claim had been an Allowed Class 7 Claim or Allowed Canadian
Impaired Unsecured Claim on the Distribution Date. Notwithstanding the
foregoing, the Disbursing Agent shall not be required to make distributions
under Article IX.D more frequently than once every 180 days or to make any
individual payments in an amount less than $25.00. Notwithstanding anything
herein to the contrary, if the Canadian Reorganization Plan is sanctioned,
disbursements to holders of Canadian Impaired Unsecured Claims shall be made in
compliance with the Canadian Reorganization Plan.

E.       DISTRIBUTION PROCEDURES FOR CLASS 8 CLAIMS AND INTERESTS

         A description of the procedure for the distribution to holders of Class
8 Claims and Interests, as well as the procedure for the establishment of a
reserve for the benefit of holders of Class 8 Claims and Interests on account of
Class 8 Claims and Interests that have not become Allowed, if any, and the
procedure for distribution to holders of Class 8 Claims and Interests that have
not become Allowed, if any, after such Claims or Interests, become Allowed
Claims or Interests will be included in the Plan Supplement.

subsidiary or subsidiaries of Reorganized PSI.

         Subject to the consent of the Required Lenders, after giving notice to
the Creditors' Committee and the Indenture Trustee, and to the extent of any
modification to the treatment of the Account Intermediaries as holders of Other
Secured Claims, the consent of the Account Intermediaries, the Debtors may
alter, amend or modify the Plan or any Exhibits thereto under section 1127(a) of

Court to remedy any defect or omission or reconcile any inconsistencies in the
Plan, the Disclosure Statement or the Confirmation Order, and such matters as
may be necessary to carry out the purposes and effects of the Plan so long as
they have obtained the prior approval of the Required Lenders and such
proceedings do not materially adversely affect the treatment of holders of
Claims or Interests under the Plan (it being specifically understood that any
settlement of a claim of the Estates against any party specifically excluded
from the releases provided in Article IV.I shall be deemed to have a material
adverse affect on the treatment of holders of Claims and Interests); provided,
however, that prior notice of such proceedings shall be served in accordance
with the Bankruptcy Rules or order of the Bankruptcy Court.


                                  ARTICLE XII.

                            RETENTION OF JURISDICTION

         Notwithstanding the jurisdiction retained in this Article XII, from and
after the Confirmation Date, the Bankruptcy Court shall not have the power to

Amended and Restated Term Credit Agreement or the rights of holders of the New

                                  ARTICLE XIII.

                           COMPROMISES AND SETTLEMENTS

         Pursuant to Fed. R. Bankr. P. 9019(a), the Debtors may compromise and
settle various Claims against them and/or claims that they may have against
other Persons. The Debtors, subject to the prior approval of the Required
Lenders, expressly reserve the right (with Bankruptcy Court approval, following
appropriate notice and opportunity for a hearing) to compromise and settle
Claims against the Debtors and claims that they may have against other Persons
up to and including the Effective Date. After the Effective Date, such right
shall pass to the Reorganized Debtors pursuant to Articles IV.E and IV.F of the
Plan.


                                  ARTICLE XIV.

                            MISCELLANEOUS PROVISIONS

A.       BAR DATES FOR CERTAIN POST-PETITION CLAIMS

         1.  Administrative Claims; Substantial Contribution Claims

         The Confirmation Order will establish an Administrative Claims Bar Date
for filing of Administrative Claims that have not been paid, released or
otherwise settled (excluding Administrative Claims arising from the sale of
goods or services to a Debtor, after the Petition Date, in the ordinary course
of business), including Substantial Contribution Claims (but not including
claims for Professional Fees or the expenses of the members of any creditors'
committee), which date will be 45 days after the Confirmation Date. Holders of
asserted Administrative Claims, other than claims for Professional Fees or the
expenses of the members of any creditors' committee, not paid prior to the
Confirmation Date must submit proofs of Administrative Claim on or before such
Administrative Claims Bar Date or forever be barred from doing so. The notice of
Confirmation to be delivered pursuant to Fed. R. Bankr. P. 3020(c) and 2002(f)
will set forth such date and constitute notice

                                       39
<PAGE>   172

of this Administrative Claims Bar Date. The Debtors or Reorganized Debtors, as
the case may be, shall have 45 days (or such longer period as may be allowed by
order of the Bankruptcy Court) following the Administrative Claims Bar Date to
review and object to such Administrative Claims before a hearing for
determination of allowance of such Administrative Claims.

         2.  Professional Fee Claims

         All final requests for compensation or reimbursement of Professional
Fees pursuant to section 327, 328, 330, 331, 503(b) or 1103 of the Bankruptcy
Code for services rendered to the Debtors or any creditors' committee prior to
the Effective Date (other than Substantial Contribution Claims under section
503(b)(4) of the Bankruptcy Code) must be filed and served on the Reorganized
Debtors and their counsel no later than 45 days after the Effective Date, unless
otherwise ordered by the Bankruptcy Court. Objections to applications of such
Professionals or other entities for compensation or reimbursement of expenses
must be filed and served on the Reorganized Debtors and their counsel and the
requesting Professional or other entity no later than 45 days (or such longer
period as may be allowed by order of the Bankruptcy Court) after the date on
which the applicable application for compensation or reimbursement was served.

B.       PAYMENT OF STATUTORY FEES

         All fees payable pursuant to Section 1930 of title 28 of the United
States Code, as determined by the Bankruptcy Court at the Confirmation, shall be
paid on or before the Effective Date.

C.       SEVERABILITY OF PLAN PROVISIONS

         If, prior to Confirmation, any term or provision of the Plan is held by
the Bankruptcy Court to be invalid, void or unenforceable, the Bankruptcy Court,
at the request of any Debtor with the consent of the Required Lenders, and to
the extent of any modification to the treatment of the Account Intermediaries as
holders of Other Secured Claims, the consent of the Account Intermediaries,
shall have the power to alter and interpret such term or provision to make it
valid or enforceable to the maximum extent practicable, consistent with the
original purpose of the term or provision held to be invalid, void or
unenforceable, and such term or provision shall then be applicable as altered or
interpreted. Notwithstanding any such holding, alteration or interpretation, the
remainder of the terms and provisions of the Plan shall remain in full force and
effect and shall in no way be affected, impaired or invalidated by such holding,
alteration or interpretation. The Confirmation Order shall constitute a judicial
determination and shall provide that each term and provision of the Plan, as it
may have been altered or interpreted in accordance with the foregoing, is valid
and enforceable pursuant to its terms.

D.       SUCCESSORS AND ASSIGNS

         The rights, benefits and obligations of any entity named or referred to
in the Plan shall be binding on, and shall inure to the benefit of, any heir,
executor, administrator, successor or assign of such entity.

E.       RELEASES AND SATISFACTION OF SUBORDINATION RIGHTS

         All Claims of the holders of the Lender Claims and the Old Debentures
against the Debtors and all rights and claims between or among such holders
relating in any manner whatsoever to any claimed subordination rights or
otherwise shall be deemed satisfied by the distributions under, described in,
contemplated by and/or implemented in Article III.C of this Plan. All other
claimed subordination rights against the holders of Old Debentures, other than
the subordination of the claims of holders of Old Debentures to the claims of or
payments to the Indenture Trustee under the Old Indenture, are deemed satisfied
by this Plan. Distributions under, described in, contemplated by and/or
implemented by this Plan to the various Classes of Claims hereunder shall not be
subject to levy, garnishment, attachment or like legal process by any holder of
a Claim, including, but not limited to, holders of Lender Claims and Old
Debenture Claims, by reason of any claimed subordination rights or otherwise, so
that each holder of a Claim shall have and receive the benefit of the
distributions in the manner set forth in the Plan.

F.       DISCHARGE OF THE DEBTORS; INJUNCTION

         1.  Discharge

         Except as otherwise provided herein or in the Confirmation Order, all
consideration distributed under the Plan shall be in exchange for, and in
complete satisfaction, settlement, discharge, and release of, all Claims (other
than those Reinstated under the Plan) of any nature whatsoever against the
Debtors or any of their assets or properties, and regardless of whether any
property shall have been distributed or retained pursuant to the Plan on account
of such Claims, upon the Effective Date, the Debtors, and each of them, shall
(i) be deemed discharged and released under section 1141(d)(1)(A) of the
Bankruptcy Code from any and all Claims, including, but not limited to, demands
and liabilities that arose before the Confirmation Date, and all debts of the
kind specified in section 502(g), 502(h) or 502(i) of the Bankruptcy Code,
whether or not (a) a proof of Claim based upon such debt is filed or deemed
filed under section 501 of the Bankruptcy Code, (b) a Claim based upon such debt
is Allowed under section 502 of the Bankruptcy Code, or (c) the holder of a
Claim based upon such debt accepted the Plan, and (ii) terminate all Interests
of the holders of (A) Other Equity Securities and (B) if Class 7 votes to reject
the Plan, Old Common Shares.

         As of the Confirmation Date, except as provided in the Plan or the
Confirmation Order, all entities shall be precluded from asserting against the
Debtors or the Reorganized Debtors, their successors or their property any other
or further claims, debts, rights, causes of action, liabilities or equity
interests relating to the Debtors based upon any act, omission, transaction or
other activity of any nature that occurred prior to the Confirmation Date;
provided however, that nothing in this Plan shall be deemed to preclude any
third party (other than the releasing parties in Article IV.I.2.(a) to the
extent provided therein) from asserting claims, debts, rights, causes of action,
liabilities or equity interests that are not property of the Estates under
section 541 of the Bankruptcy Code against any current or former officers,
directors or employees of the Debtors or Reorganized Debtors; provided further,
that notwithstanding anything contained in the Plan to the contrary, rights and
claims of the United States under environmental laws or regulations shall not be
discharged, impaired or otherwise affected by the Plan and the Chapter 11 Cases,
shall survive the Chapter 11 Cases as if the Chapter 11 Cases had not been
commenced and shall be determined in the manner and by the administrative or
judicial tribunals in which such rights or claims would have been resolved or
adjudicated if the bankruptcy cases had not been commenced. In accordance with
the foregoing, except as provided in the Plan or the Confirmation Order, the
Confirmation Order shall be a judicial determination of discharge of all such
Claims and other debts and liabilities against the Debtors and termination of
all Interests of the holders of (i) Other Equity Securities and (ii) if Class 7
votes to reject the Plan, Old Common Shares, pursuant to sections 524 and 1141
of the Bankruptcy Code, and such discharge shall void any judgment obtained
against the Debtors at any time, to the extent that such judgment relates to a
discharged Claim or terminated Interest.

         2.  Injunction

                  (a)  Injunction Related to Discharged Claims and Terminated
                       Interests

                  Except as provided in the Plan or the Confirmation Order, as
of the Confirmation Date, all entities that have held, currently hold or may
hold a Claim or other debt or liability that is discharged or an Interest or
other right of an equity security holder that is Impaired or terminated pursuant
to the terms of the Plan are permanently enjoined from taking any of the
following actions against the Debtors, Reorganized Debtors or their property on
account of any such discharged Claims, debts or liabilities or terminated
interests or rights: (a) commencing or continuing, in any manner or in any
place, any action or other proceeding; (b) enforcing, attaching, collecting or
recovering in any manner any judgment, award, decree or order; (c) creating,
perfecting or enforcing any lien or encumbrance; (d) asserting a setoff, right
of subrogation or recoupment of any kind against any debt, liability or
obligation due to the Debtors and (e) commencing or continuing any action in any
manner, in any place that does not comply with or is inconsistent with the
provisions of the Plan.

                  (b)  Released Claims

                  As of the Effective Date, all entities that have held,
currently hold or may hold a claim, demand, debt, right, cause of action or
liability that is released pursuant to Article IV.I or XIV.H are permanently
enjoined from taking any of the following actions on account of such released
claims, obligations, suits, judgments, damages, demands, debts, rights, causes
of action or liabilities: (a) commencing or continuing in any manner any action
or other proceeding; (b) enforcing, attaching, collecting or recovering in any
manner any judgment, award, decree or order; (c) creating, perfecting or
enforcing any lien or


                                       41
<PAGE>   174

encumbrance: (d) asserting a setoff, right of subrogation or recoupment of any
kind against any debt, liability or obligation due to any released entity; and
(e) commencing or continuing any action, in any manner, in any place that does
not comply with or is inconsistent with the provisions of the Plan.

                  (c)  Consent of Injunction

                  By accepting a distribution pursuant to the Plan, each holder
of an Allowed Claim or Allowed Interest receiving distributions pursuant to the
Plan will be deemed to have specifically consented to the injunctions set forth
in this Article XIV.F.

G.       COMMITTEES

         After the Confirmation Date, the Creditors' Committee shall continue to
exist as provided in this paragraph and shall be an active participant in the
Claims review process. The Creditors' Committee shall have the right to file
objections to Class 7 Claims (and Canadian Impaired Unsecured Claims that have
made the U.S. Plan Election) and, if the Canadian Reorganization Plan is
sanctioned, Canadian Impaired Unsecured Claims. The Creditors' Committee shall
be reduced to three members as they shall select and be represented by counsel
and other professionals retained by the Committee prior to the Effective Date
("Committee Professional"). Until all Distributions to Class 7 Claims have been
made pursuant to Plan, the Creditors' Committee will continue to exist and may:
(i) file such pleadings with the Bankruptcy Court as it deems appropriate or
necessary concerning implementation of the Plan; (ii) consult with the
Reorganized Debtors concerning objections to, settlements of or litigation over
Disputed Class 7 Claims; (iii) monitor, analyze and reconcile the Distributions
to holders of Class 7 Claims; and (iv) provide such other services that the
Creditors' Committee deems reasonably necessary to protect and enforce the
rights and interests of the holders of Class 7 Claims consistent with the
provisions of this Plan. Following the Effective Date, the reasonable out of
pocket fees and expenses of all Committee Professionals, and the expenses of
Committee members, shall be paid by the Reorganized Debtors within ten days
after receipt of monthly invoices from such Committee Professionals, provided,
however, that the Reorganized Debtors shall be entitled to dispute the
reasonableness of any such fees and expenses and further provided that the
Reorganized Debtors' aggregate liability for post-Confirmation fees and expenses
of the Creditors' Committee and the Creditors' Committee professionals shall not
exceed $50,000 in the event the Canadian Reorganization Plan is sanctioned, and
$75,000 in the event the Alternate Canadian Transactions are implemented. Any
unresolved, disputed fees and expenses shall be presented to the Bankruptcy
Court for resolution. If the Canadian Reorganization Plan is sanctioned, the
Canadian Counsel retained by the Creditors' Committee may incur
post-confirmation fees and expenses payable by the Reorganized Debtors up to an
aggregate $50,000.

H.       EXCULPATION AND LIMITATION OF LIABILITY; INDEMNITY

         Neither the Debtors, the Subsidiaries, the Reorganized Debtors, the
Lenders, any individual, corporation or other entity that was at any time
formerly a Lender, the ad hoc steering committee or any other committee of
holders of Lender Claims, CIBC as Administrative Agent and co-arranger under the
Pre-Petition Credit Agreement, BTCo as Syndication Agent and co-arranger under
the Pre-Petition Credit Agreement, any official committees appointed in the
Chapter 11 Cases, the DIP Agent, the DIP Co-Arrangers and the holders of DIP
Facility Claims, the Security Agent, and the Account Intermediaries, or any of
their respective present or former members, officers, directors, employees,
advisors, attorneys, or agents, shall have or incur any liability to any holder
of a Claim or an Interest, or any other party in interest, or any of their
respective agents, employees, representatives, financial advisors, attorneys, or
affiliates, or any of their successors or assigns, for any act or omission in
connection with, relating to, or arising out of, the Chapter 11 Cases,
formulating, negotiating or implementing the Plan, the Lender Lock-up Agreement
or the Allwaste Lock-up Agreement, the solicitation of acceptances of the Plan
or the Lender Lock-up Agreement, the pursuit of confirmation of the Plan, the
confirmation of the Plan, the consummation of the Plan, or the administration of
the Plan or the property to be distributed under the Plan, except for their
willful misconduct, and in all respects shall be entitled to rely reasonably
upon the advice of counsel with respect to their duties and responsibilities
under the Plan.

         Notwithstanding any other provision of this Plan, no holder of a Claim
or Interest, no other party in interest, none of their respective agents,
employees, representatives, financial advisors, attorneys, or affiliates, and no
successors or assigns of the foregoing, shall have any right of action against
any Debtor, Subsidiary or Reorganized Debtor, any Lender or any individual,
corporation or other entity that was at any time formerly a Lender, the ad hoc
steering committee or any other committee of holders of Lender Claims, CIBC as
Administrative Agent and co-arranger under the Pre-Petition Credit

                                       42
<PAGE>   175

Agreement, BTCo as Syndication Agent and co-arranger under the Pre-Petition
Credit Agreement, any official committees appointed in the Chapter 11 Cases, the
DIP Agent, the DIP Co-Arrangers and the holders of DIP Facility Claims, the
Security Agent, and the Account Intermediaries, or any of their respective
present or former members, officers, directors, employees, advisors, attorneys,
affiliates, or agents, for any act or omission in connection with, relating to,
or arising out of, the Chapter 11 Cases, formulating, negotiating or
implementing the Plan, the Lender Lock-up Agreement or the Allwaste Lock-up
Agreement, the solicitation of acceptances of the Plan, the Lender Lock-up
Agreement or the Allwaste Lock-up Agreement, the pursuit of confirmation of the
Plan, the consummation of the Plan, the confirmation of the Plan, or the
administration of the Plan or the property to be distributed under the Plan,
except for their willful misconduct.

         The Debtors, the Reorganized Debtors and the Subsidiaries hereby
jointly and severally fully indemnify each of the Lenders, any individual,
corporation or other entity that was at any time a Lender, a member of the ad
hoc steering committee or any other committee of holders of Lender Claims, CIBC
as Administrative Agent and co-arranger under the Pre-Petition Credit Agreement,
BTCo as Syndication Agent and co-arranger under the Pre-Petition Credit
Agreement, the DIP Agent, the DIP Co-Arrangers and the holders of DIP Facility
Claims, the Security Agent, and the Account Intermediaries, and their respective
agents, affiliates, directors, officers, employees, and representatives,
including counsel (collectively, the "Indemnitees") against any manner of
actions, causes of action, suits, proceedings, liabilities and claims of any
nature, costs and expenses (including reasonable legal fees) which may be
incurred by such Indemnitee or asserted against such Indemnitee arising out of
or during the course of, or otherwise in connection with or in any way related
to, the negotiation, preparation, formulation, solicitation, dissemination,
implementation, confirmation and consummation of the Plan, other than any
liabilities to the extent arising from the gross negligence or willful or
intentional misconduct of any Indemnitee as determined by a final judgment
of a court of competent jurisdiction. If any claim, action or proceeding is
brought or asserted against an Indemnitee in respect of which indemnity may be
sought from any of the Reorganized Debtors or any of the Subsidiaries, the
Indemnitee shall promptly notify the Reorganized Debtors in writing, and the
Reorganized Debtors may assume the defense thereof, including the employment of
counsel reasonably satisfactory to the Indemnitee, and the payment of all costs
and expenses. The Indemnitee shall have the right to employ separate counsel in
any such claim, action or proceeding and to consult with the Reorganized Debtors
in the defense thereof and the fees and expenses of such counsel shall be at the
expense of the Reorganized Debtors unless and until the Reorganized Debtors
shall have assumed the defense of such claim, action or proceeding. If the named
parties to any such claim, action or proceeding (including any impleaded
parties) include both the Indemnitee and any of the Reorganized Debtors or
Subsidiaries, and the Indemnitee reasonably believes that the joint
representation of such entity and the Indemnitee may result in a conflict of
interest, the Indemnitee may notify the Reorganized Debtors in writing that it
elects to employ separate counsel at the expense of the Reorganized Debtors, and
the Reorganized Debtors shall not have the right to assume the defense of such
action or proceeding on behalf of the Indemnitee. In addition, the Reorganized
Debtors shall not effect any settlement or release from liability in connection
with any matter for which the Indemnitee would have the right to indemnification
from the Reorganized Debtors, unless such settlement contains a full and
unconditional release of the Indemnitee, or a release of the Indemnitee
satisfactory in form and substance to the Indemnitee.

I.       BINDING EFFECT

         The Plan shall be binding upon and inure to the benefit of the Debtors,
all present and former holders of Claims against and Interests in the Debtors,
their respective successors and assigns, including, but not limited to, the
Reorganized Debtors and all other parties-in-interest in these Chapter 11 Cases.

J.       REVOCATION, WITHDRAWAL OR NON-CONSUMMATION

         Subject to the approval of the Required Lenders, the Debtors reserve
the right to revoke or withdraw the Plan at any time prior to the Confirmation
Date and to file subsequent plans of reorganization. If the Debtors revoke or
withdraw the Plan, or if Confirmation or Consummation does not occur, then (i)
the Plan shall be null and void in all respects, (ii) any settlement or
compromise embodied in the Plan (including the fixing or limiting to an amount
certain any Claim or Class of Claims), assumption or rejection of executory
contracts or leases effected by the Plan, and any document or agreement executed
pursuant to the Plan shall be deemed null and void, and (iii) nothing contained
in the Plan, and no acts taken in preparation for consummation of the Plan,
shall (a) constitute or be deemed to constitute a waiver or release of any
Claims by or against, or any Interests in, any Debtor or any other Person, (b)
prejudice in any manner the rights of any Debtor or any Person in any further
proceedings involving a Debtor, or (iii) constitute an admission of any sort by
any Debtor or any other Person.

SECTION 4.2 NO DISTRIBUTIONS PENDING ALLOWANCE

     Notwithstanding any other provision of the Plan, no payments or

SECTION 4.3 DISPUTED CLAIMS RESERVE

     On the Effective Date (or as soon thereafter as is practicable) the
Disbursing Agent shall establish the Disputed Claims Reserve by withholding
from the initial distribution on account of Proven Unsecured Claims an amount
of New Unsecured PIK Notes and New Common Shares calculated as if all Affected
Unsecured Claims and U.S. Impaired Unsecured Claims were Proven Unsecured
Claims and allowed U.S. Impaired Unsecured Claims under the U.S. Plan as of

and to each holder of a disputed U.S. Impaired Unsecured Claim that has become
an allowed claim under the U.S. Plan.  On the next succeeding interim
distribution date after the date that the value of a Proven Unsecured Claim has
been determined in accordance with this Plan, the Disbursing Agent shall
distribute to the holder of such Claim any New Unsecured PIK Notes and PSC
Common Shares in the Disputed Claims Reserve that would have been distributed
on the Distribution Date had such Claim been a Proven Unsecured Claim on the
Distribution Date (after giving effect to the Stock Consolidation).  After a
Final Order has been entered, or other final resolution has been reached, with
respect to each Disputed Unsecured Claim and each disputed U.S. Impaired
Unsecured Claim (i) any New Unsecured PIK Notes and PSC Common Shares that
remain in the Disputed Claims Reserve shall be distributed pro rata to holders
of Proven Unsecured Claims and holders of U.S. Impaired Unsecured Claims
allowed under the U.S. Plan.  All distributions made under this Article 4 on
account of a Proven Unsecured Claim shall be made together with any payments or
other distributions made on account of, as well as any obligations arising
from, the distributed property, as if such Proven Unsecured Claim had been a
Proven Unsecured Claim on the Distribution Date.  Notwithstanding the
foregoing, the Disbursing Agent shall not be required to make distributions
under this Article 4 more frequently than once every 180 days.

(1)  Affected Secured Lender Claims






<PAGE>   209

                                     - 16 -



     (a)  On the Effective Date, the Credit Facility Agreements shall be
          amended and restated by the Amended and Restated Term Credit
          Agreement without any further action by any party.  Each holder of a
          Proven Secured Lender Claim, in full satisfaction, settlement,
          release and discharge of and in exchange for such Proven Secured
          Lender Claim and its allowed Class 6 Claim in the U.S. Plan, shall
          receive on or as soon as practicable after the Distribution Date its
          pro rata share of (a) the Net Asset Sale Proceeds Pool, (b) the New
          Secured PIK Debt, (c) the New Senior Secured Term Debt and (d) (i) if
          the holders of U.S. Impaired Unsecured Claims vote to accept the U.S.
          Plan and the holders of Proven Unsecured Claims vote to accept the
          Plan, 5,967,052,592 New Common Shares which shall be ninety-one
          percent (91%) of the PSC Common Shares issued and outstanding as of
          the Effective Date (which shall equal 21,840,000 PSC Common Shares
          after giving effect to the Stock Consolidation) subject to Dilution,
          or (ii) if the holders of U.S. Impaired Unsecured Claims vote to
          reject the U.S. Plan, but the holders of Proven Unsecured Claims vote
          to accept the Plan, 22,800,000 PSC Common Shares which shall be
          ninety-five percent (95%) of the PSC Common Shares issued and
          outstanding as of the Effective Date plus an amount of PSC Common
          Shares equal to the aggregate number of PSC Common Shares that would
          have been available for distribution to holders of U.S. Impaired
          Unsecured Claims under the U.S. Plan had such holders voted to accept
          the U.S. Plan (based on the Applicants' estimate of the aggregate
          allowed amount of such claims), subject to Dilution, and an amount of
          New Unsecured PIK Notes equal to the amount that would have been
          distributed to holders of U.S. Impaired Unsecured Claims under the
          U.S. Plan had such holders voted to accept the U.S. Plan (based on
          the Applicants' estimate of the aggregate allowed amount of such
          claims).

     (b)  Each LC Lender will fund its pro rata share of the Unfunded LC
          Claim (i) in cash, or (ii) by foregoing distributions that it would
          otherwise receive in respect of a Claim in the amount of its pro rata
          share of the Unfunded LC Claim.  If the distributions that would
          otherwise be received by an LC Lender are insufficient to fund its
          pro rata share of the Unfunded LC Claim, such deficiency may be
          funded by foregoing distributions to the extent necessary by the
          Lender that is an affiliate of such LC Lender.  Any such cash paid or
          distributions foregone shall be reallocated pro rata among the
          holders of Proven Secured Lender Claims.  Letters of credit issued
          pursuant to the Credit Agreement that remain outstanding and undrawn
          on the Effective Date shall be replaced or, with the consent of the
          issuers of such letters of credit, supported by letters of credit

          Secured Lender Claims as holders of record of such New Common Shares.
          Each holder of a Secured Lender Claim shall vote the New Common
          Shares distributed to it

                                     - 17 -


          under the Plan in favour of each of the matters set forth in Section
          6.1(2)(c) hereof.

(2)  Affected Unsecured Claims

     Subject to Section 5.2, on or as soon as reasonably practicable after, the
later of (i) the Distribution Date or (ii) the date such Affected Unsecured
Claim becomes a Proven Unsecured Claim,

     (a)  if the holders of Proven Unsecured Claims vote to accept the
          Plan then each holder of a Proven Unsecured Claim shall receive in
          full satisfaction, settlement, release and discharge of and in
          exchange for such Proven Unsecured Claim, its pro rata share
          (determined as described below) of (i) US$60 million of New Unsecured
          PIK Notes to be issued pursuant to Article 7 of this Plan and the
          U.S. Plan (subject to certain election rights of holders of U.S.
          Impaired Unsecured Claims) and (ii) 327,860,033 New Common Shares
          which shall be five percent (5%) of the PSC Common Shares issued and
          outstanding as of the Effective Date (which shall equal 1,200,000 PSC
          Common Shares, after giving effect to the Stock Consolidation),
          subject to Dilution (in each case, such distribution shall be shared
          pro rata with the holders of U.S. Impaired Unsecured Claims under the
          U.S. Plan) and the holders of Affected Unsecured Lender Claims shall
          be deemed to have waived any and all distributions to which they
          would be entitled under the Plan as holders of Affected Unsecured
          Lender Claims, including the benefit of any and all contractual
          subordination provisions in respect of their Unsecured Lender Claims;
          or

     (b)  if the holders of Proven Unsecured Claims vote to reject the
          Plan, then the holders of such Claims shall not receive anything on
          account of such Claims.

     For purposes of distributions to holders of Proven Unsecured Claims, the
pro rata calculations shall include in the determination of the Face Amount of
all Proven Unsecured Claims (i) if the class of holders of U.S. Impaired
Unsecured Claims under the U.S. Plan votes to accept the U.S. Plan, the
aggregate amount of all allowed U.S. Impaired Unsecured Claims or (ii) if the
class of holders of U.S. Impaired Unsecured Claims under the U.S. Plan votes to
reject the U.S. Plan, the Applicant's estimate of the aggregate amount of all
allowed U.S. Impaired Unsecured Claims.  Claims under the Canadian Plan will be
converted to United States' dollars ("US$") for purposes of distributions at a
rate of CDN$1.465097244 per US$1.00.

                                   ARTICLE 6

          exchanged such Claim for an undivided co-ownership interest in all of
          the Claims under the Credit Agreement in the same aggregate principal

          against one or more of the Applicants which becomes a Proven
          Unsecured Claim shall be deemed to have exchanged such Claim for an
          undivided co-ownership interest in all Proven Unsecured Claims in the
          same aggregate amount.

(2)  Corporate Action

1   Shareholder Rights Plan.  On the Effective Date, PSC shall implement the
Shareholder Rights Plan.

2   Stock Consolidation.  On the Effective Date, if the holders of U.S.
Impaired Unsecured Claims under the U.S. Plan have voted to accept the U.S.
Plan and the holders of Affected Unsecured Claims under this Plan have voted
to accept this Plan, PSC shall take all steps necessary to implement the Stock
Consolidation.

     (c)  Shareholder Approval.  On or immediately after the Effective
          Date and the distribution of New Common Shares to holders of Affected

          PSC to allow for the implementation of the Stock Consolidation; (iv)

          to the Effective Date.

     (d)  Directors and Officers.  On the Effective Date, the new board
          of directors for PSC will consist of nine (9) directors, who will be
          nominated by holders of Lender Claims.  The nominees of the holders
          of Lender Claims shall include two (2) members of the existing PSC
          board of directors and will include two (2) members nominated by High
          River Limited Partnership ("High River") provided that High River and
          any holders of Lender Claims acting in concert with it beneficially
          own at least twenty-five (25%) of the Lender Claims.  If one or both
          of the nominees from the existing board is a nominee on that board of
          High River or persons acting in concert with it, that person will be
          counted as a High River nominee on the slate for the new board of
          directors.

SECTION 0.1 ASSET TRANSFERS

     If the conditions set forth in Section 5.2 are not met, or if the holders
of Proven Unsecured Claims vote to reject this Plan, the reorganization of the
Applicants will be effected through the transfer of the business of the
Applicants as a going concern to one or more direct






<PAGE>   213

                                     - 20 -



or indirect subsidiaries of PSI.  This transfer will occur in conjunction with
the implementation of the U.S. Plan through the enforcement of remedies
available to the Lenders, and will be more fully described in a supplement to
this Plan (the "Plan Supplement") that will be filed prior to the meeting of
the holders of Affected Secured Lender Claims.  The transferee(s) will assume
the Claims which would have been Unaffected Obligations if the arrangement
described in Section 5.1 had been implemented.  The proceeds paid on the
transfers will be distributed in accordance with the legal priority of the
claims against the transferred assets.  In that case, the Affected Unsecured
Claims will not be compromised, but it is expected that no distributions will
be made to the holders of such Claims.  The holders of Affected Unsecured
Claims will have the right, but will not be required, to elect to participate
in distributions under the U.S. Plan as provided in that plan.

SECTION 0.2 PLAN RELEASES

     Subject to Section 5.2 and to the approval of the Plan by the Required
Majority of each Class of Creditors, the following releases will become

SECTION 0.3 INJUNCTION RELATED TO RELEASES

     The Confirmation Order will enjoin the prosecution, whether directly,
derivatively or otherwise, of any claim, obligation, suit, judgment, damage,
demand, debt, right, cause of action, liability or interest released,
discharged or terminated pursuant to the Plan.

SECTION 0.4 REVOCATION OF CERTAIN RELEASES

     The revocation of any release of any director, officer or employee
pursuant to Section 6.3 hereof shall be void ab initio to the extent that a
court of competent jurisdiction, including, but not limited to the Court,
determines that such director, officer or employee has provided the factual
information reasonably requested by the Applicants or any successor pursuant to
Section 6.3(1) or the Administrative Agent or its successor pursuant to Section
6.3(2).

SECTION 0.5 SUBSTANTIVE CONSOLIDATION FOR PURPOSES OF TREATING AFFECTED CLAIMS

     The Plan is premised upon the substantive consolidation of the Applicants
only for purposes of treating Affected Secured Lender Claims and Affected
Unsecured Claims under the Plan, including for voting, Plan sanction and
distribution purposes.  This Plan does not contemplate substantive
consolidation of the Applicants with respect to Unaffected Obligations.
Subject to Section 5.2 and the approval of the Plan by the Required Majority of
each Class of Creditors, on the Effective Date, (a) all guarantees of any
Applicants of the payment, performance or collection of another Applicant with
respect to Affected Claims shall be deemed eliminated and cancelled; (b) any
obligation of any Applicant and all guarantees with respect to Affected Claims
thereof executed by one or more of the other Applicants shall be treated as a
single obligation and any obligation of two or more Applicants, and all
multiple Affected Claims against such entities on account of such joint
obligations, shall be treated and allowed only as a single Affected Unsecured
Claim against the consolidated Applicants; and (c) each Affected Claim of any
Applicant shall be deemed filed against the consolidated Applicants and shall
be deemed one Affected Claim against and obligation of the consolidated
Applicants.  Except as set forth in this Section 6.6, such substantive
consolidation shall not (other than for purposes related to the Plan) (a)
affect the legal and corporate structures of the Applicants, (b) cause any
Applicant to be liable for any Claim under the Plan, for which it otherwise is
not liable and the liability of any Applicant for any such Claim shall not be
affected by such substantive consolidation, (c) affect Intercompany Claims of
Applicants against Applicants, or (d) affect Subsidiary Interests.

SECTION 0.6 ASSUMED INDEMNIFICATION OBLIGATIONS

     The Assumed Indemnification Obligations (other than Excluded
Indemnification Obligations) shall be deemed effective as of the Effective Date
without any further action by any party.


                                   ARTICLE 1
                       PROVISIONS GOVERNING DISTRIBUTIONS

SECTION 1.1 DISTRIBUTIONS FOR CLAIMS ALLOWED AS OF THE EFFECTIVE DATE






<PAGE>   219

                                     - 26 -



     Except as otherwise provided herein or as ordered by the Court,
distributions to be made on account of Claims that are Proven Unsecured Claims
and Proven Secured Lender Claims as of the Effective Date shall be made not
later than the Distribution Date.  Distributions on account of Claims that
first become Proven Unsecured Claims or a Proven Secured Lender Claim after the
Effective Date shall be made pursuant to Articles 4,5 and 7 of this Plan.
Notwithstanding the date on which any distribution of securities is actually
made to a holder of a Claim that is a Proven Unsecured Claim or a Proven
Secured Lender Claim on the Effective Date, as of the date of the distribution
such holder shall be deemed to have the rights of a holder of such securities
distributed as of the Effective Date.

SECTION 1.2 INTEREST ON CLAIMS

     Unless otherwise specifically provided for in this Plan or the
Confirmation Order, interest shall not accrue or be paid on Claims after the
Date of Filing, and no holder of a Claim shall be entitled to interest accruing
on or after the Date of Filing on any Claim.  Interest shall not accrue or be
paid upon any Disputed Unsecured Claim in respect of the period from the Date
of Filing to the date a final distribution is made thereon if and after such
Disputed Unsecured Claim becomes a Proven Unsecured Claim.

SECTION 1.3 DISTRIBUTIONS BY DISBURSING AGENT

     (a)  The Disbursing Agent shall make all distributions required
          under this Plan (subject to the provisions of Articles 4, 5 and 7
          hereof).  If the Disbursing Agent is an independent third party
          designated by the Applicants to serve in such capacity, such
          Disbursing Agent shall receive, without further Court approval,
          reasonable compensation for distribution services rendered pursuant
          to the Plan and reimbursement of reasonable out-of-pocket expenses
          incurred in connection with such services from the Applicants on
          terms acceptable to the Applicants.  No Disbursing Agent shall be
          required to give any bond or surety or other security for the
          performance of its duties unless otherwise ordered by the Court.

     (b)  At the close of business on the Distribution Record Date, the
          transfer records for the Lender Claims shall be closed, and there
          shall be no further changes in the record holders of Lender Claims.
          The Applicants, the Disbursing Agent and the Administrative Agent for
          the Lenders shall have no obligation to recognize any transfer of
          Lender Claims after the Distribution Record Date and shall be
          entitled instead to recognize and deal for all purposes hereunder
          with only those record holders as of the close of business on the
          Distribution Record Date.

SECTION 1.4 CALCULATION OF DISTRIBUTION AMOUNTS

(1) Common Shares

     No fractional New Common Shares shall be issued or distributed under the
Plan or by PSC or the Disbursing Agent.  Each Person entitled to receive New
Common Shares will receive the total number of whole New Common Shares to which
such Person is entitled.  Whenever any distribution to a particular Person
would otherwise call for distribution of a fraction of a New






<PAGE>   220

                                     - 27 -



Common Share, the actual distribution of shares shall be rounded to the next
higher or lower whole number as follows:  (a) fractions ? or greater shall be
rounded to the next higher whole number, and (b) fractions of less than ? shall
be rounded to the next lower whole number.  The total number of New Common
Shares to be distributed to a Class of Claims shall be adjusted as necessary to
account for the rounding provided for in this Section 7.4.  No consideration
shall be provided in lieu of fractional shares that are rounded down.

(2)  New Unsecured PIK Notes

     New Unsecured PIK Notes will be issued in denominations of US$1,000 and
such fractions thereof as is necessary.

SECTION 1.5 DELIVERY OF DISTRIBUTIONS

     Distributions to holders of Proven Unsecured Claims shall be made by the
Disbursing Agent (a) at the last known address of such persons or at the
addresses set forth on the Proofs of Claim filed by such holders (b) at the
addresses reflected in the Affected Unsecured Creditors List, or (c) at the
addresses set forth in any written notices of address changes delivered to the
Disbursing Agent after the date of any related Proof of Claim.  If any holder's
distribution is returned as undeliverable, no further distributions to such
holder shall be made unless and until the Disbursing Agent is notified of such
holder's then current address, at which time all missed distributions shall be
made to such holder without interest.  No undeliverable distributions will go
back to the Applicants. All claims for undeliverable distributions in respect
of Proven Unsecured Claims must be made on or before the expiration of the
eighteenth (18th) month following the Effective Date, after which date all
unclaimed property shall be distributed pro rata to the other holders of Proven
Unsecured Claims and the Claim of any holder or successor of such holder with
respect to such property shall be discharged, and forever barred,
notwithstanding any federal or provincial laws to the contrary.  Nothing
contained in the Plan shall require the Applicants or any Disbursing Agent to
attempt to locate any holder of a Proven Unsecured Claim.

SECTION 1.6 WITHHOLDING AND REPORTING REQUIREMENTS

     In connection with this Plan and all distributions hereunder, the
Disbursing Agent shall, to the extent applicable, comply with all tax
withholding and reporting requirements imposed by any federal, state,
provincial, local, or foreign taxing authority, and all distributions hereunder
shall be subject to any such withholding and reporting requirements.  The
Disbursing Agent shall be authorized to take any and all actions that may be
necessary or appropriate to comply with such withholding and reporting
requirements.  Notwithstanding any other provision of the Plan:  (i) each
holder of a Proven Claim that is to receive a distribution pursuant to the Plan
shall have sole and exclusive responsibility for the satisfaction and payment
of any tax obligations imposed by any governmental unit, including income,
withholding and other tax obligations, on account of such distribution, and
(ii) no distribution shall be made to or on behalf of such holder pursuant to
the Plan unless and until such holder has made arrangements satisfactory to the
Disbursing Agent for the payment and satisfaction of such tax obligations.  Any
distributions to be distributed pursuant to the Plan shall, pending the
implementation of such arrangements, be






<PAGE>   221

                                     - 28 -



treated as an undeliverable distribution pursuant to Section 7.5.  It is the
Applicants' intent that distributions under the Plan to holders of Claims are
in respect of, and to be applied to, principal first and then interest.

SECTION 1.7 SET-OFF TO APPLY

     The Applicants may, but shall not be required to, set off against any
Claim, and the payments or other distributions to be made pursuant to the Plan
in respect of such Claims, claims of any nature whatsoever that the Applicants
may have against the holder of such Claim, provided, however, that neither the
failure to do so nor the allowance of any Claim hereunder shall constitute a
waiver or release by the Applicants of any such claim that the Applicants may
have against such holder.  Notwithstanding anything to the contrary, the
Applicants will not exercise any right of setoff against any Lender, any agents
under the Credit Agreements or the DIP Facility Agreement, the Account
Intermediaries or the DIP Lenders.


                                   ARTICLE 2

                              AND UNEXPIRED LEASES

SECTION 2.1 CONTRACTS AND LEASES

     Except as otherwise provided in the Plan, or in any contract, instrument,
release, indenture or other agreement or document entered into in connection
with the Plan, as of the Effective Date each Applicant shall be deemed to have
ratified each executory contract and unexpired lease to which it is a party,
unless such contract or lease (i) was previously repudiated or terminated by
such Applicant, (ii) previously expired or terminated pursuant to its own
terms, or (iii) as otherwise set forth in an amendment to the Affected
Unsecured Claims List as being an executory contract or unexpired lease to
repudiate or terminate.  Without limiting the foregoing, all obligations of the
Applicants with respect to Other Equity Securities and Excluded Indemnification
Obligation shall be terminated and cancelled.

SECTION 3.1 CONFIRMATION OF PLAN

     (a)  Provided that the conditions in Section 5.2 are satisfied by
          the deadline set forth therein and the Plan is approved by the

          Creditors.

SECTION 3.2 PARAMOUNTCY

     Subject to the obligations of the Applicants pursuant to the Exit Facility
or the Amended and Restated Term Credit Agreement, from and after the Effective
Date, any conflict between the Plan and the covenants, warranties,
representations, terms, conditions, provisions or obligations, expressed or
implied, of any contract, mortgage, security agreement, indenture, trust
indenture, loan agreement, commitment letter, agreement for sale, by-laws of
the Applicants, lease or other agreement, written or oral and any and all
amendments or supplements thereto existing between one or more of the Creditors
and the Applicants as at the Effective Date will be deemed to be governed by
the terms, conditions and provisions of the Plan and the Confirmation Order,
which shall take precedence and priority.

SECTION 3.3 WAIVER OF DEFAULTS

     Other than in relation to the Exit Facility or the Amended and Restated
Term Credit Agreement, from and after the Effective Date, each Creditor shall
be deemed to have waived any and all defaults then existing or previously

provision, condition or obligation, expressed or implied, in any contract,
agreement, mortgage, security agreement, indenture, trust indenture, loan
agreement, commitment letter, agreement for sale, lease or other agreement,

guarantee, shall be deemed to have been rescinded.

SECTION 3.4 COMPROMISE EFFECTIVE FOR ALL PURPOSES

     The payment, compromise or other satisfaction of any Claim under the Plan,
if sanctioned and approved by the Court shall be binding upon such Creditor,
its heirs, executors, administrators, successors and assigns, for all purposes.

SECTION 3.5 PARTICIPATION IN DIFFERENT CAPACITIES

     Creditors whose Claims are affected by this Plan may be affected in more
than one capacity.  Each such Creditor shall be entitled to participate
hereunder in each such capacity.  Any action taken by a Creditor in any one
capacity shall not affect the Creditor in any other capacity unless the
Creditor agrees in writing.

SECTION 3.6 MODIFICATION OF PLAN

     Subject to the consent of the Required Lenders, the Applicants reserve the
right to file any modification of, amendment or supplement to the Plan by way
of a supplementary plan or plans of compromise or arrangement or both filed
with the Court at any time or from time to time prior to the Creditors'
Meetings Dates, in which case any such supplementary plan or plans of
compromise or arrangement or both shall, for all purposes, be and be deemed to

modification to the Plan at any Creditors' Meeting.  After such Creditors'
Meetings (and both prior to and subsequent to the Confirmation Order) and
subject to the consent of the Required Lenders, the Applicants may at any time
and from time to time vary, amend, modify or supplement the Plan if the Court
determines that such variation, amendment, modification or supplement is of a
minor, immaterial or technical nature that would not be materially prejudicial
to the interests of any of the Creditors under the Plan or the Confirmation
Order and is necessary in order to give effect to the substance of the Plan or
the Confirmation Order.

held by the Court to be invalid, void or unenforceable, the Court, at the
request of any Applicant, with the consent of the Required Lenders, and to the
extent of any modification to the treatment of the Account Intermediaries as
holders of Other Secured Claims, the consent of the Account Intermediaries,
shall have the power to alter and interpret such term or provision to make it
valid or enforceable to the maximum extent practicable, consistent with the
original purpose of the term or provision held to be invalid, void or
unenforceable, and such term or provision shall then be applicable as altered
or interpreted.  Notwithstanding any such holding, alteration or
interpretation, the remainder of the terms and provisions of the Plan shall
remain in full force and effect and shall in no way be affected, impaired or
invalidated by such holding, alteration or interpretation.  The Confirmation
Order shall constitute a judicial determination and shall provide that each
term and provision of the Plan, as it may have been altered or interpreted in
accordance with the foregoing, is valid and enforceable pursuant to its terms.

SECTION 3.13 SUCCESSORS AND ASSIGNS

     The rights, benefits and obligations of any entity named or referred to in

have or incur any liability to any holder of a Claim or any other party in
interest, or any of their respective agents, employees, representatives,
financial advisors, attorneys, or affiliates, or any of their successors or
assigns, for any act or omission in connection with, relating to, or arising

<PAGE>   227

                                     - 34 -



the solicitation of acceptances of the Plan or the Lender Lock-up Agreement,
the pursuit of confirmation of the Plan, the confirmation of the Plan, the
consummation of the Plan, or the administration of the Plan or the property to
be distributed under the Plan, except for their willful misconduct, and in all
respects shall be entitled to rely reasonably upon the advice of counsel with
respect to their duties and responsibilities under the Plan.

     Notwithstanding any other provision of this Plan, no holder of a Claim, no
other party in interest, none of their respective agents, employees,
representatives, financial advisors, attorneys, or affiliates, and no
successors or assigns of the foregoing, shall have any right of action against
any Applicant, Subsidiary, any Lender, any individual, corporation or other
entity that was at any time formerly a Lender, the ad hoc steering committee or
any other committee of holders of Lender Claims, CIBC as Administrative Agent
and co-arranger under the Credit Agreement, BTCo as Syndication Agent and
co-arranger under the Credit Agreement, any official committees appointed in
CCAA Proceedings or the Chapter 11 Cases, the DIP Agent, the DIP Co-Arrangers
and the holders of DIP Facility Claims, the Security Agent, and the Account
Intermediaries, or any of their respective present or former members, officers,
directors, employees, advisors, attorneys, affiliates, or agents, for any act
or omission in connection with, relating to, or arising out of, the CCAA
Proceedings, formulating, negotiating or implementing the Plan or the Lender
Lock-up Agreement, the solicitation of acceptances of the Plan or the Lender
Lock-up Agreement, the pursuit of confirmation of the Plan, the consummation of
the Plan, the confirmation  of the Plan, or the administration of the Plan or
the property to be distributed under the Plan, except for their willful
misconduct.

     The Applicants and the Subsidiaries hereby jointly and severally fully
indemnify each of the Lenders, any individual, corporation or other entity that
was at any time a Lender, the ad hoc steering committee or any other committee
of holders of Lender Claims, CIBC as Administrative Agent and co-arranger under
the Credit Agreement, BTCo as Syndication Agent and co-arranger under the
Credit Agreement, the DIP Agent, the DIP Co-Arrangers and the holders of DIP
Facility Claims, the Security Agent, and the Account Intermediaries, and their
respective agents, affiliates, directors, officers, employees, and
representatives, including counsel (collectively, the "Indemnitees") against
any manner of actions, causes of action, suits, proceedings, liabilities and
claims of any nature, costs and expenses (including reasonable legal fees)
which may be incurred by such Indemnitee or asserted against such Indemnitee
arising out of or during the course of, or otherwise in connection with or in
any way related to, the negotiation, preparation, formulation, solicitation,
dissemination, implementation, confirmation and consummation of the Plan, other
than any liabilities to the extent arising from the gross negligence or willful
or intentional misconduct of any Indemnitee as determined by a final judgment
of a court of competent jurisdiction.  If any claim, action or proceeding is
brought or asserted against an Indemnitee in respect of which indemnity may be
sought from any of the Applicants or any of the Subsidiaries, the Indemnitee
shall promptly notify the Applicants in writing, and the Applicants may assume
the defense thereof, including the employment of counsel reasonably
satisfactory to the Indemnitee, and the payment of all costs and expenses.  The
Indemnitee shall have the right to employ separate counsel in any such claim,
action or proceeding and to consult with the Applicants in the defense thereof
and the fees and expenses






<PAGE>   228

                                     - 35 -



of such counsel shall be at the expense of the Applicants unless and until the
Applicants shall have assumed the defense of such claim, action or proceeding.
If the named parties to any such claim, action or proceeding (including any
impleaded parties) include both the Indemnitee and any of the Applicants or
Subsidiaries, and the Indemnitee reasonably believes that the joint
representation of such entity and the Indemnitee may result in a conflict of
interest, the Indemnitee may notify the Applicants in writing that it elects to
employ separate counsel at the expense of the Applicants, and the Applicants
shall not have the right to assume the defense of such action or proceeding on
behalf of the Indemnitee.  In addition, the Applicants shall not effect any
settlement or release from liability in connection with any matter for which
the Indemnitee would have the right to indemnification from the Applicants,
unless such settlement contains a full and unconditional release of the
Indemnitee, or a release of the Indemnitee satisfactory in form and substance
to the Indemnitee.

SECTION 3.15 BINDING EFFECT

     The Plan shall be binding upon and inure to the benefit of the Applicants
and all present and former holders of Claims.

SECTION 3.16 REVOCATION, WITHDRAWAL, OR NON-CONSUMMATION

     Subject to the approval of the Required Lenders, the Applicants reserve
the right to revoke or withdraw the Plan at any time prior to the Confirmation
Date and to file subsequent plans of reorganization or arrangement.  If the
Applicants revoke or withdraw the Plan, or if the Confirmation does not occur,
(i) the Plan shall be null and void in all respects, (ii) any settlement or
compromise embodied in the Plan (including the fixing or limiting to an amount
certain any Claim or Class of Claims), assumption or termination, repudiation
of executory contracts or leases effected by the Plan, and any document or
agreement executed pursuant to the Plan shall be deemed null and void, and
(iii) nothing contained in the Plan, and no acts taken in preparation for
consummation of the Plan, shall (a) constitute or be deemed to constitute a
waiver or release of any Claims by or against any Applicant or any other
Person; (b) prejudice in any manner the rights of any Applicant or any Person
in any further proceedings involving an Applicant; or (c) constitute an
admission of any sort by any Applicant or any other Person.

SECTION 3.17 GOVERNING LAW

     This Plan shall be governed by and construed in accordance with the laws
of the Province of Ontario and the federal laws of Canada applicable therein.
Subject to the Protocol, any questions as to the interpretation or application

NOTE 1

         The Liquidation Analysis reflects an estimate by Ernst and Young Inc.
with input from the management of PSC (the "Management") of the proceeds that
would be realized if the Debtors, the Canadian Debtors and the non-filing
Subsidiaries (collectively "Consolidated PSC") were to be liquidated in
accordance with the respective insolvency legislation in the jurisdiction
governing the individual Subsidiaries (e.g. Chapter 7 of the United States
Bankruptcy Code for United States Subsidiaries, the Canadian Bankruptcy and
Insolvency Act for Canadian Subsidiaries, etc.). The Liquidation Analysis is
based on the projected assets as at October 31, 1999. The Liquidation Analysis
assumes that all operations will cease effective October 31, 1999.

         It is foreseeable that a trustee under a Chapter 7 filing in the United
States, under Canadian Bankruptcy and Insolvency Act or under comparable
bankruptcy legislation in other jurisdictions would identify certain operations
which may be able to continue as profitable operations during the filing and the
trustee may be able to obtain additional recovery under a going-concern sale.
Such operation would require operating financing without assurance as to
ultimate sales proceeds. As a result, realizations may be higher or lower than
those anticipated in the above Liquidation Analysis. However, given the level of
the secured debt outstanding, any additional potential recovery would only serve
to improve the position of the Secured Lenders and would not likely result in
any recovery to the unsecured creditors.

         Underlying the Liquidation Analysis are a number of estimates and
assumptions that, although developed and considered reasonable by Management,
are inherently subject to significant business, economic and competitive
uncertainties and contingencies beyond the control of Consolidated PSC and
Management, and upon assumptions with respect to a liquidation, decisions which
could be subject to change. Accordingly, there can be no assurance that the
values reflected in the Liquidation Analysis would be realized of Consolidated
PSC were, in fact, to undergo such a liquidation, nor can there be any assurance
that the Bankruptcy Court will accept such analysis or concur with such
assumptions in making its determinations under section 1129(a) of the Bankruptcy
Code. In addition, any liquidation ultimately undertaken necessarily would take
place under future circumstances that cannot presently be predicted with
certainty. Accordingly, although the analysis that follows is necessarily
presented with numerical specificity, if Consolidated PSC's estates were in fact
liquidated, the actual liquidation proceeds could vary from the amounts set
forth above. Such actual liquidation proceeds could be materially lower or
higher than the amounts set forth above, and no representation or warranty can
be or is being made with respect to the actual proceeds that would be generated
in liquidations of Consolidated PSC under Chapter 7 of the United States
Bankruptcy Code, under the Canadian Bankruptcy and Insolvency Act or under
comparable legislation in other jurisdictions. The liquidation valuations have
been prepared solely for purposes of estimating the proceeds available in a
Chapter 7, Canadian and/or other liquidation of Consolidated PSC's assets and do
not represent values that may be appropriate for any other purpose, including
the values applicable in the context of the Plan. Nothing contained in these
valuations is intended as or constitutes a concession or admission for any
purpose other than the presentation of a hypothetical liquidation analysis.

NOTE 2

         Cash is based on the estimated book balances as at October 31, 1999,
plus an estimate for outstanding checks of $37.0 million which would be added to
the Cash book balance as at October 31, 1999, based on the Company's
disbursement patterns from January to May 1999 and assuming cheques remain
outstanding for an average of 7 days. The estimated book balance excludes any
estimate of restricted cash or cash which may be held in escrow by the Secured
Lenders or DIP Lender (refer to Note 16). No setoff against the DIP Facility
Claim has been calculated. These amounts may be subject to right of setoff and
combination of account in favor of the DIP lenders. In such case, the amount of
the DIP Facility Claim and the amount available for distribution would be
affected without impact on the net shortfall to the Secured Lender Claim. The
Liquidation Analysis assumes that operations during the liquidation period cease
and therefore no additional Cash will be available for distribution except for
net proceeds generated by liquidating non-Cash assets.

<PAGE>   252

NOTE 3

         Accounts Receivable is based on receivables net of a provision for
doubtful accounts as all receivables for which allowances have previously been
established are assumed to be uncollectible. In addition, accounts which would
be subject to a trade creditor's right of setoff have been assumed to be
approximately 2% of net receivables and accounts receivable where collection may
be impaired as a result of the bonding companies collecting the receivables or
payments applicable to project completion costs have been estimated to be
approximately 2% of net receivables.

         The recovery of receivables is based on Management's estimate of
receivables, given such factors as the aging of the receivables, the time and
effort necessary to make inquiries and the potential uncollectible accounts. The
estimated realization range is below book value as it is assumed that credit
quality will deteriorate once Consolidated PSC ceases to be a continuing entity.
It is assumed that off-set claims, warranty and similar claims will be advanced
in such circumstances.

NOTE 4

         Inventory is projected to consist of unprocessed metal scrap. The
inventory is assumed to be liquidated for 75% of net book value, before
operating costs and liquidation consultant fees based on Management's estimate.
No reductions have been made for potential reclamation Claims and/or 30-day good
Claims which would otherwise reduce the recovery value.

NOTE 5

         Other Current Assets consists of additional third party receivables,
work in process, miscellaneous parts and supplies not held for resale, and
prepaid expenses relating to insurance and professional fees. The October 31,
1999 forecast balances have been allocated to these categories based on
Consolidated PSC's historical information. Proceeds from prepaid expenses and
third party receivables have been assumed to be recoverable at 0% and 31% of the
estimated book value at October 31, 1999 respectively. Work in process and
parts/supplies have been assumed to be recoverable at 0% and 10% of the
estimated book value at October 31, 1999 respectively.

NOTE 6

         Landfill includes the landfill site, capitalized costs relating to the
landfill and the cost of the operating licenses. For the purposes of the
liquidation value, it has been assumed that the operating licenses can be
transferred to a purchaser and the landfill site can be sold in a liquidation.
In consideration for the license transfer, it is assumed the purchaser will
assume the environmental liabilities associated with this site.

NOTE 7

         Land, Buildings & Leaseholds are included at the estimated net book
value and may include improvements to properties which are under lease
agreements. All leaseholds at non-owned locations are assumed to have no
recovery value as the leases would be abandoned at the date of the liquidation.
No assessment of the potential value of leases which may have been below market
lease rates has been calculated or included in the liquidation value. The value
of the owned real estate has been based on recent appraisals and tax
assessments, to the extent they are available, Management's estimates of the
current real estate market conditions, the environmental condition of the
property and the estimated effect of liquidation of these properties in a
relatively short period of time.

NOTE 8

         Equipment includes equipment that is under capital leases, furniture
and fixtures, heavy machinery (including cranes, scales, shredders and
containers), vehicles, office equipment and computers (including hardware and
software). Proceeds are estimated net of an estimate of the amount of secured
capital lease claims. The recovery value has been based on Management's estimate
for market conditions, the costs of

                                       3

<PAGE>   253

removal and transportation of certain of the heavy equipment to the purchaser's
location, and the effect of liquidating the equipment in a relatively short
period of time.

NOTE 9

         Other Non-Current Assets are forecast to include third-party
investments, intangibles, long term receivables from third parties and
miscellaneous long term assets. These have been valued based on estimated
recoveries provided by Management. Third-party investments have been valued
based on current market values, if available, expressions of interest and
Management's estimate of the investments' underlying asset values. Recoveries
for third-party investments are assumed to be $13.7 million. Recoveries for
intangibles are assumed to be zero. Recoveries for long term receivables are
assumed to be approximately $0.4 million. Recoveries for miscellaneous assets
are assumed to be approximately $0.5 million.

NOTE 10

         Estimated recoveries for potential assets which are not reflected in
the forecast balance sheet have not been quantified but may include recoveries
from outstanding lawsuits, fidelity insurance coverage, potential pension
surpluses, proprietary technology and potential equity in operating leases. The
valuation and inclusion of these items would in no way effect the position of
the unsecured creditors and would only serve to increase the estimated recovery
by the Secured Lenders.

NOTE 11

         Phencorp International Finance Inc. ("Phencorp"), a wholly-owned Irish
captive finance Subsidiary of Consolidated PSC, has loaned funds to certain of
PSC's Subsidiaries and its assets comprise intercompany long-term receivables
and Cash on hand. Phencorp has no material third party receivables. A
liquidation of all PSC's Subsidiaries would result in Phencorp's operations
being wound up and its intercompany receivables being written off thereby
generating tax losses. Management has estimated that approximately $5.0 million
could be recovered from the carryback of these losses.

NOTE 12

         Phencorp Reinsurance Company Inc. ("Phencorp Reinsurance"), a
wholly-owned Barbados insurance Subsidiary of PSC has forecast October 31, 1999
net book value of assets of $37.4 million, the estimated gross recovery of which
is estimated at $39.5 million. In order to realize on this investment, Phencorp
Reinsurance would be wound up and all obligations satisfied. Based on
discussions with Management, the value of the potential insurance claims against
Phencorp Reinsurance are estimated at approximately $25.9 million, and the
estimated tax liability and other costs of windup have been estimated to be $7.7
million resulting in a net liquidation value of approximately $5.9 million.

NOTE 13

         Estimated Costs of Liquidation. Professional Fees have been estimated
at 3% of the net realizations on the assets. Additional out-of-pocket expenses,
professional fees, operating and administrative overhead costs have been
included. The completion of the majority of asset realizations is assumed to
take approximately six months to complete and therefore substantial overhead
costs would continue to be incurred during the liquidation period. No potential
statutory lien claimants, reclamation claimants, employee termination and
related costs, or secured creditors (other than the Secured Lenders, as defined
in the Plan) have been included in this Liquidation Analysis. These costs would
only serve to reduce the net realization on the assets and in no way would
change the amount distributable to the holders of the Unsecured Claims.

NOTE 14

         The DIP Facility Claim has been forecast to be $20.0 million at October
31, 1999 under the assumption that the Company will have fully utilized the DIP
Letter of Credit Facility. It is assumed at October 31, 1999 that the Company
will not have drawn on the remainder of the DIP Facility. The DIP Facility has a
first charge on the assets, in priority to the secured Lender claims.

                                       4

<PAGE>   254

NOTE 15

                  Secured Lender Claim. The amount estimated for the debt
outstanding under the Pre-Petition Credit Agreement is based on the projected
balance at October 31, 1999 and has not been adjusted to reflect any right of
setoff. Interest on the Pre-Petition Credit Facility Debt has been accrued to
June 25, 1999. It is assumed that the Secured Lenders Claim is properly secured,
valid and enforceable over all the assets of Consolidated PSC.

NOTE 16

                  Restricted Cash represents an estimate of the remaining cash
held in escrow by the Secured Lenders or DIP Lender as a result of asset
divestiture proceeds. Approximately $33.3 million is estimated to be available
from the first $93.0 million of asset divestiture proceeds and approximately
$5.8 million is estimated to be available from the excess asset divestiture
proceeds. It is assumed that these funds will be offset against the Secured
Lender Claim.

NOTE 17

         Secured and outstanding letters of credit have been estimated to be
$65.2 million (at face value) which are assumed to be called upon the conversion
of the case to a Chapter 7 in the United States and concurrent liquidation
proceedings in Canada and other jurisdictions. This amount has been reduced by
$26.6 million of cash collateral forecast to be held by the administrative agent
on behalf of the Secured Lenders.

                         PROJECTED FINANCIAL INFORMATION



A.       INTRODUCTION

This projected financial information (the "Projections") was prepared to show
the estimated consolidated financial position, results of operations and cash
flows, and capitalization of Philip Services Corp. , the Debtors, the Canadian
Debtors and the non-filing Subsidiaries (collectively the "Company" or
"Consolidated PSC") following December 31, 1999, which is assumed to be the date
the Plan is implemented (the "Effective Date") and assume that the Canadian
Reorganization Plan is implemented. The Projections are based on the assumptions
discussed below and should be read together with the information in Article VII
of the Disclosure Statement entitled "Certain Factors to be Considered".

All capitalized terms not defined in this exhibit have the same meanings
ascribed to them in the Disclosure Statement to which this exhibit is attached.

THE PROJECTIONS WERE NOT PREPARED WITH A VIEW TOWARD COMPLIANCE WITH THE
GUIDELINES ESTABLISHED BY THE AMERICAN INSTITUTE OF CERTIFIED PUBLIC ACCOUNTANTS
("AICPA"), THE FINANCIAL ACCOUNTING STANDARDS BOARD ("FASB") OR THE CANADIAN
INSTITUTE OF CHARTERED ACCOUNTANTS ("CICA") REGARDING PROJECTIONS OR FUTURE
ORIENTED FINANCIAL INFORMATION. FURTHERMORE, THE PROJECTIONS HAVE NOT BEEN
AUDITED OR REVIEWED BY THE COMPANY'S INDEPENDENT AUDITORS. THE INDEPENDENT
AUDITORS OR THE FINANCIAL ADVISORS OF THE COMPANY HAVE NOT EXAMINED OR COMPILED
THE PROJECTIONS PRESENTED HEREIN AND, ACCORDINGLY, ASSUME NO RESPONSIBILITY FOR
THEM. WHILE PRESENTED WITH NUMERICAL SPECIFICITY, THE PROJECTIONS ARE BASED UPON
A VARIETY OF ESTIMATES AND ASSUMPTIONS, WHICH ALTHOUGH DEVELOPED AND CONSIDERED
REASONABLE BY MANAGEMENT, MAY NOT BE REALIZED AND ARE SUBJECT TO SIGNIFICANT
BUSINESS, ECONOMIC AND COMPETITIVE UNCERTAINTIES AND CONTINGENCIES, MANY OF
WHICH ARE BEYOND THE CONTROL OF THE COMPANY AND ITS MANAGEMENT. CONSEQUENTLY,
THE PROJECTIONS SHOULD NOT BE REGARDED AS A REPRESENTATION OR WARRANTY BY THE
COMPANY, OR ANY OTHER PERSON, AS TO THE ACCURACY OF THE PROJECTIONS OR THAT THE
PROJECTIONS WILL BE REALIZED. ACTUAL RESULTS MAY VARY MATERIALLY FROM THOSE
PRESENTED IN THESE PROJECTIONS.

The Projections included herein are:

1.   Projected Pro Forma Consolidated Balance Sheet, Statement of Earnings, and
     Statement of Cash Flows of Consolidated PSC as at December 31, 1999 based
     on an opening historical consolidated balance sheet as at June 30, 1999
     adjusted for the effects of projected operating activity up to the
     Effective Date (assumed to be December 31, 1999), and reflecting the
     financial transactions necessary to implement the Plan including
     adjustments necessary to reflect "fresh start" accounting as promulgated by
     the AICPA Statement of Position 90-7 entitled "Financial Reporting By
     Entities in Reorganization Under the Bankruptcy Code" ("SOP 90-7").

2.   Projected Consolidated Balance Sheets of Reorganized Consolidated PSC as at
     December 31, 1999, December 31, 2000 and December 31, 2001.

3.   Projected Consolidated Statements of Earnings of Reorganized Consolidated
     PSC for the two fiscal years in the period ending December 31, 2001.

4.   Projected Consolidated Statements of Cash Flows of Reorganized Consolidated
     PSC for each of the two fiscal years in the period ending December 31,
     2001.
<PAGE>   257

5.   Projected Capitalization Table of Reorganized Consolidated PSC as at
     December 31, 1999, December 31, 2000 and December 31, 2001.

The projections have been prepared on the basis of generally accepted accounting
principles of the United States, consistent with those currently utilized by the
Company in the preparation of its historical consolidated financial statements
except as noted in the accompanying assumptions. The Projections should be read
in conjunction with the significant assumptions, qualifications and notes set
forth below and with the audited consolidated financial statements for fiscal
year ended December 31, 1998 included in the 1998 Annual Form 10-K and June 30,
1999 Form 10-Q as filed with the Securities and Exchange Commission included in
Exhibit D of the Disclosure Statement.

The Projections present managements' estimate of the expected consolidated
financial position, results of operations, cash flows, and capitalization of
Reorganized Consolidated PSC. Accordingly, the Projections reflect managements'
judgement, as of the date of this Disclosure Statement, of expected future
operating and business conditions which are subject to change. All estimates and
assumptions shown within the Projections were developed by management. The
assumptions disclosed herein are those management believes are significant to
the Projections. There will be differences between projected and actual results
because events and circumstances frequently do not occur as expected.

The Projections assume implementation of the Plan on December 31, 1999 and
adjustments necessary to reflect "fresh start" accounting. The Projections are
based on a number of estimates and assumptions that, although developed and
considered reasonable by management, are inherently subject to significant
business, economic and competitive uncertainties and contingencies, some of
which are beyond the control of the Company and its management. Accordingly,
there can be no assurance the projected results will be realized and actual
results may vary materially from those projected. If actual results are lower
than those projected or if the assumptions used in formulating the Projections
are not realized, Reorganized Consolidated PSC's operating results and cash
flows, may be materially and adversely affected.

The Company does not, as a matter of course, publish its business plans and
strategies or projections of its anticipated financial position, results of
operations or cash flows. Accordingly, the Company does not intend, and
disclaims any obligation to, (a) furnish updated business plans or projections
to holders of Claims or Equity Interests, or (b) include such updated
information in any documents which may be required to be filed with the
Securities and Exchange Commission or applicable Canadian Securities Regulatory
Authorities. The Company does not intend to update or otherwise revise the
Projections to reflect circumstance existing since their preparation or to
reflect the occurrence of unanticipated events, even in the event that any or
all of the underlying assumptions are shown to be in error. Furthermore, the
Company does not intend to update or revise the Projections to reflect regular
quarterly and annual financial statements, and the accompanying discussion and
analysis. The Company's Quarterly Reports on Form 10-Q and Annual Reports on
Form 10-K will contain disclosure concerning the Company's actual financial
condition and results of operations.

Management does not intend to revise the Projections solely to reflect
circumstances arising after the date of this Disclosure Statement or to reflect
the occurrence of unanticipated events. Management assumes no responsibility to
advise recipients of the Projections about any subsequent changes.

While management believes the assumptions underlying the projected financial
information for the projection period, when considered on an overall basis, are
reasonable in light of current circumstances and expectations, no assurance can
be given that the projections will be realized. The Company urges the holders of
claims to consider carefully the underlying assumptions in reaching their
determination of whether to accept or reject the Plan.

A.       PHILIP SERVICES CORP.'S BUSINESS

The Company is an integrated metals recovery and industrial services company,
which provides metals recovery and processing services, by-products recovery and
industrial outsourcing services to major industry sectors from
<PAGE>   258

over 260 locations across North American and Europe. The Company's primary base
of operations is in the United States.

The Company's business is organized into two operating divisions, the Metals
Services Group and the Industrial Services Group.

Metals Services Group ("MSG")

MSG's primary business operations are ferrous processing and industrial metals
services

The ferrous metals operations include the collection and processing of ferrous
scrap materials for shipment to steel mills and the provision of significant
brokerage services for scrap materials. The industrial metals services include
engineering and construction management, on-site services, by-product management
and coil processing and distribution services to steel mills. MSG primarily
services the steel, foundry and automotive industries.

During 1998, the Company decided to discontinue its Non-Ferrous and Copper
operations. The operations related to the recovery of copper and aluminum from
wire and cable scrap, the management of material recycling centers for
telecommunications industry customers, the processing of aluminum dross and the
production of aluminum deoxidizing agents and aluminum alloys from aluminum
scrap.

Industrial Services Group ("ISG")

ISG is an integrated provider of by-products recovery and industrial outsourcing
with a network of over 230 facilities. By-products recovery includes solvent
distillation, paint overspray recovery, organic and inorganic waste collection
processing and polyurethane recycling. Industrial outsourcing services includes
cleaning and maintenance, waste collection and transportation, container and
tank cleaning, turnaround and outage services, mechanical contracting,
refractory services, decommissioning and remediation, analytical services and
emergency response services.

The Company historically provided municipal water and wastewater management
services in Ontario and the United States through its investment in Philip
Management Utilities Corporation ("PUMC"), which was sold on May 18, 1999 and is
now treated as a discontinued operation.

C.       GENERAL IMPROVEMENTS

Overall, the Projections assume that the Company' operations will return to the
profitability levels achieved in early 1998 and that these levels will be
achieved by the end of 2000 and sustained for 2001.

Key Improvements encompassed in these Projections include:

MSG

MSG will decrease its emphasis on owning metal and the classic buy, process,
sell operations. Instead MSG will focus its strategy on dedicating its
processing capabilities and its commercial and technical expertise to its client
base - the steel industry. The foundation of this strategy will be long term
service contracts as well as supply arrangements. Furthermore, this strategy
will mitigate competing with MSG's customers for metals units, and concentrate
MSG's efforts on helping customers lower cost and increase productivity. This
strategic shift will also result in a redistribution of our total costs, not
only reducing costs of goods sold, but diminishing inventories and working
capital requirements.

MSG's integration program will be realized by removing the divisional barriers
through the Company's reorganization. MSG will rationalize facilities and
overhead, share functions and transfer skills as required.
<PAGE>   259

Furthermore, MSG will begin to run its metals recycling and brokerage business
without the marked differentiation between US and Canada.

Rather than trying to create market differentiation by becoming bigger than its
competitors, MSG will establish its goals to become the best, through a customer
focused, technology based and service driven mentality.

ISG

Despite the financial difficulties the Company experienced during 1998 and 1999,
ISG was generally successful in retaining customers by managing key customer
relationships. However, in order to retain these customers, ISG was forced to be
aggressive in pricing to retain volume and counter competitive attacks.
Financial uncertainty also contributed to increased costs as suppliers required
additional security to do business with the Company. Both factors contributed to
reduced margin. The Projections for fiscal 2001 assume a margin improvement due
to reduced costs as a result of returning to normal operating conditions
encompassing stabilized relationships with suppliers and customers.

D.       SIGNIFICANT ASSUMPTIONS FOR PROJECTIONS FOR THE SIX MONTHS ENDED
         DECEMBER 31, 1999 AND FOR THE TWO FISCAL YEARS IN THE PERIOD ENDING
         DECEMBER 31, 2001

1.       Consolidation

These Projections include PSC and its subsidiaries on a consolidated basis.

2.       Economic Assumptions

The overall economic assumption with respect to MSG assumes that the domestic
steel market improves from that experienced in 1998. For ISG, the general
assumption is that the general trend of industrial companies to outsource
non-core industrial services continues. Manufacturers are seeking to improve
competitiveness by focusing on their core business and by reducing costs in
non-core, non-revenue producing activities. Three key trends that have developed
as a result are: (i) increased outsourcing of non-core services, (ii) a
reduction by manufacturers in the number of vendors from which outsourced
services are purchased and (iii) maximizing resource recovery opportunities from
waste and by-product streams.

3.       Sales Growth

The Projections are based upon a return to the historical levels achieved by the
Company in the first quarter of fiscal 1998 which was prior to the financial
difficulties which caused erosion of revenue in the second half of 1998.

4.       Operating Expenses

Included in the six-month 1999 and the fiscal year 2000 Projections are
approximately $26.2 million and $5.5 million respectively of non-recurring
expenses related to the professional fees incurred in connection with the
restructuring of the Company, expenses related to Key Employee Retention
Program, and consulting fees related to Year 2000 compliance issues. These costs
are not included in the Projections for fiscal 2001.

5.       Selling, Administrative and General Expenses ("SG&A")

The new management team is currently reviewing the level of expenses and will
likely institute a variety of programs to streamline the organization,
potentially exiting certain lines of business and divesting of certain assets.
The Company has not included any costs of such reorganization in the
Projections, as they are not determinable at this time, but has shown a
reduction in the level of expenses in Fiscal 2001 projections.
<PAGE>   260

6.       Income Taxes

The projected provisions for income taxes have been calculated in accordance
with FASB Statement No. 109, "Accounting for Income Taxes" ("SFAS No. 109").

For purposes of the Projections, the provision for income taxes assume the
Company will have consolidated 1999 net operating loss ("NOL") carryforward
remaining after the debt forgiveness. On a consolidated income basis, as a
combined result of forecast operating losses and utilization of NOLs, the
Company will not be taxable in the six months ended December 31, 1999 and each
of the years 2000 and 2001, other than for US state taxes of approximately $2.0
million annually.

The above should be read together with the information in Article X of the
Disclosure Statement entitled "Income Tax Consequences of the Plan".

7.       Dividends

These Projections assume no dividends are paid during the period ending December
31, 2001.

8.       Capital Expenditures

These Projections assume aggregate capital expenditures of $28.9 million in the
six months ended December 31, 1999, $69.9 million in fiscal 2000 and $74.2
million in fiscal 2001. These amounts are estimated to be sufficient to replace
and maintain the Company's existing equipment with minimal growth expectations.

9.       Inventory and Accounts Payable

These Projections anticipate trade credit terms gradually improving by mid
fiscal 2000, which represent historical levels enjoyed by the Company prior to
experiencing financial difficulties.

Inventory levels are assumed to increase to normal carrying levels by the end of
2000.

10.      Exit Financing

These Projections assume the Company has access to a working capital facility in
the aggregate amount of $100.0 million to repay the debtor in possession
financing in an aggregate amount of up to $100.0 million, fund letter of credit
requirements and potential working capital needs. It is assumed that sufficient
eligible accounts receivable will be available to support the borrowing base
necessary to fully draw the Exit Financing, if necessary.

11.      Bonding Facilities

The Projections assume that ISG continues to have the support of its Bonding
Companies and that the available bonding facility will be sufficient for ISG to
operate its business in the normal course and enable ISG to achieve its
projected revenues.

12.      Basis of Fiscal 2000 and Fiscal 2001 forecasts

The Projections for fiscal years 2000 and 2001 have been prepared taking into
account projected results for fiscal 1999. The fiscal 2000 and 2001 Projections
are based on assumptions with respect to market demand, cost reductions and
selling prices. The nature of the Company's operations result in a minimal
backlog, typically less than $100.0 million, with respect to known customers and
sales volume. In view of this fact the Projections for fiscal years 2000 and
2001 may materially change depending on prevailing business conditions.
<PAGE>   261

13.      Divestiture of Assets

Sale of PUMC

The Projections exclude the Company's 68% investment in Philip Utilities
Management Corp. ("PUMC") which was sold in May 1999 for gross proceeds of $70.1
million and the assumption of PUMC's bank indebtedness. Pursuant to the terms of
the amended Lock-Up Agreement the Company repaid $70.0 million of existing
Syndicate debt and the amount of New Senior Secured Term Debt was reduced from
$300.0 million to $250.0 million.

Sale of Other Assets

The Company has identified other non-core assets which are to be sold. The
Projections assume that the Company will receive net proceeds of $1.3 million
during the six months ended December 31, 1999 and $1.9 million in fiscal 2000
and $0 in fiscal 2001.

14.      Risks and Uncertainties inherent in the Projections

The Projections include significant assumptions, including, the ability of the
Company to retain existing customers and obtain new customers, obtain projected
profit margins on existing and future business, return to more normal levels of
ferrous trading volumes and pricing, realize potential sales value of certain
non-core assets and the realization of cost savings and other efficiencies.
Other factors that could affect the Company's future operating results and
financial condition include the assumption by the Company of an ongoing trend by
industrial companies to outsource non-core industrial services, increased price
competition and the entrance of new competitors, the ability to fully integrate
previously acquired businesses and upgrading existing financial and management
information systems.

The assumptions and estimates underlying the Projections are inherently
uncertain and are subject to a wide variety of significant business, industry,
economic and competitive risks and uncertainties that could cause actual results
to differ materially from those projected, including, among others, risks and
uncertainties relating to: (i) the ability of the Company to achieve substantial
improvements in the results of the operations of its major divisions; (ii) the
potentially adverse effects that the filing of the Chapter 11 and CCAA cases
could have on the Company's business relationships, including relationships with
customers, suppliers, employees, regulators and bonding companies; (iii) the
ability of the Company to effect the Plan in a timely manner and within the
timeline contemplated by the Plan; (iv) the expected enhancements of the
Companies' ability to attract and profitable exploit new business opportunities;
(v) the ability of the Company to generate sufficient funds from operations and
to gain access to sufficient working capital financing to meet its working
capital and capital expenditure needs (vi) the ability of the Company to retain
key employees and senior management at the corporate and divisional level both
during the insolvency proceedings and after consummation of the Plan; (vii)
industry business cycles and the effect of economic downturns in the automotive,
petrochemical and steel industries and (viii) the effect that a new Board of
Directors will have on the implementation of the overall strategy underlying the
Company's Projections. The new Board of Directors and the new CEO are currently
reviewing the overall level of expenses and may institute a cost savings
program. The Company has not included any costs of reorganization in the
Projections.

E.       SIGNIFICANT ASSUMPTIONS FOR THE PROJECTED CONSOLIDATED BALANCE SHEET OF
         PHILIP SERVICES CORP. AS OF DECEMBER 31, 1999

1.   The Projected Consolidated Balance Sheet assumes the Plan is confirmed by
     the Bankruptcy Courts in the United States and Canada and the terms of the
     Plan are implemented on the Effective Date.

2.   "Fresh start" accounting adjustments have been made to reflect the
     estimated adjustments necessary to develop "fresh start" reporting in
     accordance with SOP 90-7. "Fresh Start" reporting requires that the
     reorganization value of the Company be allocated to the Company's assets in
     conformity with APB Opinion 16 "Business Combinations", for transactions
     reported on the basis of the purchase method. Any reorganization value less
     than the amount allocable to specific tangible or identified tangible
     assets is to be allocated back to its tangible
<PAGE>   262

     assets on a pro rata basis after offsetting the intangible assets. For
     purposes of the Projections, the reorganization value was assumed to be
     $550 million. Based on an assumed total debt (including capital lease
     obligations) of $407.4 million, the equity book value of the Company is
     calculated to be approximately $142.6 million.

     The foregoing assumptions and related calculations were made solely
     for purposes of preparing the Projections. The reorganized Company
     will be required to determine the amount by which its reorganization value
     as of the Effective Date exceeds, or is less than, the fair value of its
     assets as of the Effective Date. Such determination will be based upon the
     fair values as of that time, which could be materially greater or lower
     than the values assumed in the foregoing computations, and may be based on
     a different methodology, including, with respect to the valuation of
     Reorganized Consolidated PSC's reorganization value. In all events, such
     valuation, as well as the determination of its actual liabilities, will be
     made as of the Effective Date, and the changes between the amounts of any
     or all of the foregoing items as assumed in the Projections and the actual
     amounts thereof as of the Effective Date may be material.

3.   No assumptions have been made to reflect the number of shares to be issued
     pursuant to the Plan and no assumptions have been made to reflect any share
     consolidation which may occur in order to implement the Plan. Therefore,
     projected 'Earnings per Share' information has not been disclosed in the
     Projections, contrary to SOP 90-7.

4.   The significant "fresh start" accounting adjustments are summarized as
     follows:

     -   Based on the Reorganization value of the Reorganized Consolidated
         PSC, the book value of the assets would require a total write down
         of $79.0 million. The Company anticipates recognizing $50.0 million
         of this write down prior to the Plan confirmation date. The remaining
         $29.0 million will be recognized on the Effective Date.

     -   The fair value of the identifiable assets in excess of the
         reorganization value ("Negative goodwill") of $29.0 million is
         allocated to reduce the fair values of certain non-current assets in
         accordance with generally accepted accounting principles.

September 9, 1999

PRIVATE AND CONFIDENTIAL

Mr. Phillip C. Widman,
Executive Vice-President and
         Chief Financial Officer
Philip Services Corp.
100 King Street West,
P.O. Box 2440, LCD 1,
Hamilton, Ontario

Dear Sirs:    Re: Valuation of Philip Services Corp. for Purposes of
                  Restructuring Filings

In connection with the filing of a plan of reorganization under Chapter 11 of
the Bankruptcy Code in the United States and under the Companies' Creditors
Arrangement Act in Canada, for purposes of restructuring secured debt, certain
unsecured debt and shareholders' equity, Philip Services Corp. ("Philip", "PSC"
or "the Company", where these references are to the parent corporation and all
its subsidiaries as a consolidated entity) retained Ernst & Young Corporate
Finance Inc. ("EYCF") to prepare an estimate of the post-confirmation, going
concern total enterprise value of Philip. For purposes of our initial value
analysis we made reference to financial data for the Company's first quarter of
1999 ending March 31 together with business plan and financial projection data
for its 1999 and 2000 fiscal years, with all monetary amounts stated in United
States currency and expressed in financial statements prepared in accordance
with United States generally accepted accounting principles.

Subsequent to that initial analysis, the Company undertook a process of review
and updating of its business plans and projections with consequent revisions to
the expected amounts, patterns and timing of revenue and earnings recoveries
(with earnings defined as Earnings Before Interest, Taxes, Depreciation and
Amortization or "EBITDA") that are expected to accrue as the business emerges
from the uncertainties inherent in the restructuring process. These plan
revisions resulted in reductions of near term expected results to reflected a
management assessment that it would take longer to return the operations to
previously achieved performance levels (as adjusted for actions to exit
operations considered to be unattractive to the Company going forward into a
restructured operating environment.) The business plan revisions involved

restatement of 1999 and 2000 expected results and the addition of data for the
year 2001. For purposes of our valuation analysis, we performed a general review
of the basis for these adjustments to the previously reviewed plans and
incorporated the relevant revisions into our estimates of the post-confirmation,
going concern total enterprise value of Philip.

The valuation analysis reported on herein has been undertaken under an
assumption that the proposed restructuring has been completed and confirmed in
both the Canadian and United States jurisdictions with effect on or about
December 31, 1999 such that assumed conditions at the latter date are the
reference point for the value estimation process. The valuation estimates
developed by EYCF have been prepared for the sole purpose of the reorganization
filings and certain related and ancillary uses in connection with the
restructuring process. The valuation has accordingly not been prepared in
contemplation of any other uses and EYCF does not accept any responsibility for
costs or losses resulting from unauthorized use of this estimated value range
outside its intended context of consideration.

We have developed our valuation estimates by reference to the concept of fair
market value which we consider to have a comparable substantive meaning in
Canada and the United States although the conventional method of expression is
somewhat different in the two countries. In that regard, in Canada the concept
is expressed as "the highest cash price that would prevail in an open and
unrestricted market between willing and informed parties acting at arm's length
where neither party is under any compulsion to transact" while in the United
States the general wording is "the amount at which the property would change
hands between a willing seller and a willing buyer when neither is under
compulsion and when both have reasonable knowledge of the relevant facts". The
focus of the value analysis is upon the total enterprise value of the business
defined as the aggregate long term capital employed in the operations without
regard to how it might be financed with debt and equity funds and as viewed from
a trading market perspective on corporate worth.

In order to estimate a range of enterprise values for Philip, EYCF undertook a
review of both Company information and externally sourced data bearing on the
objective of analysing economic value. Included in such information were: (1)
historical financial and operating data respecting the different segments of the
businesses in which Philip is engaged (generally described as the Metal Services
Group ("MSG") and the Industrial Services Group ("ISG"); (2) management prepared
prospective operating and financial data for the ongoing businesses over the
period 1999 to 2001, including revisions to the data as originally reviewed; (3)
management prepared information on miscellaneous assets and operations to the
extent they were considered relevant to the estimation of post-confirmation
total enterprise value; (4) publicly available information on comparable
companies and comparable transactions in other businesses where market data were
considered to be relevant to the estimation of the enterprise value of a
restructured Philip and including an updating review of such data in conjunction
with the



<PAGE>   268


                                      - 3 -


revisions to the business plan data as referred to above; (5) general economic
and industry data considered to provide a relevant background to the estimation
of post-confirmation total enterprise value for the Philip operations; (6) such
details of the restructuring plan as were considered relevant to the estimation
of total enterprise value; and (7) such other information and analyses as EYCF
considered necessary or appropriate to its analysis and estimate of the value
range. EYCF applied selected analytical procedures to interpret the information
assembled from the Company and elsewhere in the process of formulating the
judgements necessary to the objective of estimating a range of total enterprise
values for PSC.

In preparing its analysis and estimate of a range of values on this basis, EYCF
assumed and relied upon the presumed accuracy and completeness of all of the
financial and other information that was made available to it by the Company or
its representatives, as well as the data obtained from public sources. EYCF did
not undertake any independent verification of such information and assumes no
responsibility for performing any such verification. EYCF has assumed that the
financial projections provided to it have been prepared by management in good
faith and on a basis reflecting the best available judgements and estimates of
the management of the Company and its operating segments as to the prospective
future financial performance of the businesses and that both original forecasts
and the subsequent revisions thereto reflect management's best judgements at the
time the relevant plans were prepared. To the extent these assumptions prove
unwarranted in the event -- and in the nature of the case the process of
forecasting future results of operations for a complex business such as PSC is
virtually certain to involve some deviation from plans and projections --
adjustments of the valuation results of the EYCF review as described herein may
be indicated, and such adjustments may be material. In this regard, in
accordance with the terms of its engagement, EYCF is under no obligation to
revise the value estimates developed herein which are solely predicated on the
assumptions required for their development.

In addition to the foregoing considerations, EYCF relied upon the following
major assumptions in developing the range of indicated values for PSC:

     *        That the total enterprise value of PSC is appropriately
     ascertained as the aggregate of enterprise value estimates for its major
     MSG and ISG operating segments less a deduction for the burden of corporate
     overheads on such values plus estimated net values for its holdings of
     redundant assets and other interests that should be viewed as relevant to
     the value of the post-confirmation corporate entity.

     *        That the post-confirmation total enterprise value of the Company
     should be ascertained on a basis which excludes the value of any assets
     planned to be disposed of prior to the December 31, 1999 reference date as
     set out in the Company's plans where such values will not be available to

     *        That management estimates of provisions required to deal with such
     matters as environmental liability exposures and lawsuits in which the
     Company has been named as a defendant, viewed on a going concern basis as
     to timing of possible expenditures, represent appropriate provisions for
     the contingencies involved and their relevance to the estimation of going
     concern enterprise value; and that the Company has made adequate provisions
     and arrangements to deal with potential year 2000 computer issues in its
     own operations and that the latter will not be seriously disrupted by such
     problems as may originate with the Company's suppliers, customers or other
     parties with which it is involved.

     *        That the confirmation applications will be successful and the
     operating businesses will emerge from the restructuring process with
     sufficient financial capacity to undertake the actions required to pursue
     management's plans for the future of the restructured entity.

     *        That there will be a general continuation of the present
     management group at Philip under conditions where pursuit of the plan
     underlying the restructuring proposal will be the focus of future
     development of the businesses so long as market and operating circumstances
     warrant such actions.

     *        That for purposes of valuing PSC on a post-confirmation basis when
     viewed as a stand alone going concern business, no recognition of a
     possible control premium is warranted; nor should possible synergistic
     benefits that might be available from a combination of the business with a
     comparable sized operator having similar business attributes and, for
     example, available fixed overhead cost capacity, be assumed for valuation
     purposes.

On the basis of these assumptions and the various analyses, reviews, discussions
and considerations considered necessary to the formulation of the requisite
valuation judgements, EYCF has estimated the aggregate enterprise value of
Philip on a post-confirmation going concern basis to fall in a range from $ 500
million to $ 600 million. (Particulars of the manner in which this range of
values was ascertained are set out in the attached Appendix A although the
analysis has primarily been focused upon estimating the aggregate rather than
the component value amounts.) This value range represents a notional or
hypothetical value based on the application of valuation techniques and factors
to operating and financial position data for the businesses of PSC under
assumptions considered appropriate to the estimation of post-confirmation going
concern enterprise value. As such, this valuation range does not purport to
represent valuation levels that might be reflected in public markets for debt
and equity securities that might be issued by the Company under various
prospective capital market and operating circumstances which the Company might
encounter. This range of values is considered by EYCF to be warranted for PSC at
the total enterprise value level on the basis of the information

respecting the Company and the environment in which it will operate as provided
to or developed by EYCF in the course of the valuation review described herein.

The following is a brief summary of the financial and valuation analyses
performed by EYCF in order to arrive at its estimates of the enterprise value of
Philip as described above.

     *        To obtain a framework and context for considering values for the
     various components of Philip, EYCF compared selected data and ratios on
     publicly traded companies having some similarities to the operations of the
     Philip business segments where generally relevant valuation factors were
     either observable from market data or could be derived with reasonable
     facility. In appropriate circumstances such data included calculations of
     revenue, EBITDA, and EBIT ratios for consideration in relation to relevant
     operating data for the Philip business segments. While data for the
     companies selected for this purpose was employed in formulating judgements
     respecting the Philip businesses, none of the companies selected was
     entirely comparable to the Company's business segments. As a result, direct
     inferences from the observed valuation factors on the comparable companies
     to the value of the Philip operating segments was not possible and various
     analyses and judgements with respect to the complex of factors involved had
     to be made in order to relate the public company data to the total
     enterprise valuation of the Philip operations.

     *        Some consideration of valuation factors indicated by acquisition
     transactions in shares of companies with operations having some similarity
     to those of the Philip businesses was also undertaken. However, because of
     changes in underlying market conditions and other factors, strong
     comparisons with the PSC operations were not judged to be reflected in
     these transactions so that only broad indications of the likely zone of
     total enterprise valuation factors could be derived from these data.

     *        To develop valuation information based on the future business
     plans and related projected cash flows of the Philip businesses, EYCF
     estimated ranges of enterprise values for the different business segments
     in relation to their estimated unlevered cash flows together with total
     enterprise terminal values quantified on a capitalized perpetual return
     basis. The discounted cash flow values indicated by these analyses resulted
     from the application of discount rates developed to reflect estimates of
     the cost of capital that would apply to the various business units at the
     enterprise value level, under conditions where they were operating as
     segments of the overall Philip business and on a going concern,
     post-confirmation basis. While these calculations necessarily involved the
     use of formulas to convert valuation factor and cash flow data into value
     estimates, the inputs to such calculations were developed through a process
     of judgement and not simply as a matter of applying observed data to the
     subject company context.

                                      - 6 -



     *        EYCF applied a number of procedures to assess the sensitivity of
     the valuation results to key factors involved in the estimation process to
     assist with the process of formulating an overall valuation judgement as to
     the range within which the estimated total enterprise value of Philip
     should be judged to lie.

     *        In addition to the going concern valuation estimates for the
     operating segments of Philip as developed on the basis described above,
     EYCF also estimated values for a number of relatively minor ancillary
     operations and asset positions of the overall Philip corporate undertaking
     and assigned values to the net corporate level operating costs associated
     with the Company's consolidated operating structure as a deduction from the
     operations and asset values as otherwise determined.

The foregoing summary does not purport to be a full description of the
procedures and analyses that EYCF performed in order to develop the estimated
valuation range set out above. Philip is a complex business and development of
valuation estimates in relation to its various segments necessarily involved a
myriad of judgements, estimates and interpretations leading to an overall result
and the processes involved are not amenable to detailed description or
summarization. In addition, strong and clearly relevant comparisons of the
Philip operations to similar businesses could not be established on the basis of
available information, in part because of the unique attributes of the Company's
operations and in part because conditions in markets for certain of its segments
were generally in an unstable state over some part of the period of the review
with the result that unrepresentative financial performance was generally
pervasive in the industry. A general result of these conditions was that
necessary valuation judgements had to be based on a combination of currently
observable data informed by more general principles and considerations bearing
on the valuation of industrial business operations. EYCF gave various weights to
the variety of factors considered in performing its valuation analyses but does
not consider that any one factor or analysis should be viewed as determinative
of the results obtained as all such considerations interact in the development
of necessary valuation judgements.

   submitted proofs of claim agreeing with the scheduled amount, but also
   filed additional proofs of claim for administrative priority claims
   in the amount of $4,300 each as employee wages/benefits earned within

   Claims Agent a letter explaining that they did not disagree with the
   amounts scheduled, but believed a portion was owed as an administrative
   expense. The administrative expense amounts are not included in this list
   as the amounts would not be part of Class 7 under the Plan.

8   The Attorney for Elias Hernandez sent a letter accepting the $25,000 offer.

9   Gary and Bob Chazen, Michael Mallen, Dale Hixson and Jeff Straton each
    submitted proofs of claim agreeing with the scheduled amount, but also
    filed additional proofs of claim for administrative priority claims in
    the amount of $4,300 each as employee wages/benefits earned within 90 days

    Agent a letter explaining that they did not disagree with the amounts
    scheduled, but believed a portion was owed as an administrative expense.
    The administrative expense amounts are not included in this list as the

14   This proof of claim indicates that $4,300 of the claimed amount
     should be treated as a priority claim. In addition, Andrew Luntz filed a
     duplicate claim for a lesser time period against the Luntz Corporation in
     the of $387,028.21.

15   Gary and Bob Chazen, Michael Mallen, Dale Hixson and Jeff Straton each
     submitted proofs of claim agreeing with the scheduled amount, but also
     filed proofs of claim for administrative priority claims in the amount of
     $4,300 each as employee wages/benefits earned within 90 days of the
     petition. The attorney for these creditors sent the Claims Agent a letter
     explaining they did not disagree with the amounts scheduled, but believed
     a portion owed as an administrative expense. The administrative expense
     amounts are included in this list as the amounts would not be part of
     Class 7 under the Plan.

16   The attorney for McCombs sent a letter electing not to file proof of
     claim but instead to accept scheduled amount.

         4. Treatment of Certain Claims. Any holder of a claim that was served
with a proof of claim setting their claim amount at zero or in an unknown amount
or as disputed, contingent or unliquidated, and did not timely, pursuant to
either the Bankruptcy Code or any order of the Bankruptcy Court, file a proof of
claim with the Bankruptcy Court or the Claims and Noticing Agent controverting
such classification of their claim, SHALL NOT BE TREATED AS A CREDITOR WITH
RESPECT TO SUCH CLAIM FOR PURPOSES OF (I) RECEIVING DISTRIBUTIONS UNDER THE
PLAN, OR (II) VOTING ON THE PLAN.

              Please note that pursuant to the Plan, as of the Effective Date
each of the Debtors will be deemed to have assumed each executory contract and
unexpired lease to which it is a party, unless such contract or lease (i) was
previously assumed or rejected by one of the Debtors, (ii) previously expired or
terminated pursuant to its own terms, or (iii) as otherwise set forth in the
schedule to be provided in the Plan Supplement as being an executory contract or
unexpired lease to reject, provided however, that the Debtors reserve their
right, at any time prior to the Confirmation Date, to amend the schedule to be
provided in the Plan Supplement to delete an unexpired lease or executory
contract therefrom or add any unexpired lease or executory contract thereto. In
addition, the Plan calls for certain Restructuring Transactions by which certain
Debtors may be dissolved or merged into other Debtors. In such an event, certain
executory contracts and unexpired leases may be assigned from one Debtor to
another.

              All creditors who are parties to executory contracts and unexpired
leases which are assumed according to the above procedures will be afforded an
opportunity assert claims for cure, if any, no later than 30 days after the
Confirmation Date.

         5. Record Date. August 18, 1999, shall be the record date for
determining (a) the creditors and equity security holders entitled to receive
solicitation packages, and (b) the creditors entitled to vote to accept or
reject the Plan.

         6. Information and Documents. Any party in interest wishing to obtain
information about the solicitation procedures or copies of the Disclosure
Statement, the Plan, or any exhibits thereto may request such information or

                                  NEWS RELEASE

                   COMPANY FILES AMENDED RESTRUCTURING PLANS
               LENDERS CONFIRM THEIR SUPPORT FOR PHILIP SERVICES
              UNSECURED CREDITORS COMMITTEE SUPPORTS THE U.S. PLAN

Hamilton, Ontario - September 20, 1999:  Philip Services Corp. (TSE/ME: PHV)
today announced that the Company has filed an Amended and Restated Plan of
Compromise and Arrangement in Canada (the "Canadian Plan") under the Companies'
Creditors Arrangement Act ("CCAA"), and an Amended Joint Plan of Reorganization
("the U.S. Plan") and a Disclosure Statement under Chapter 11 of the U. S.
Bankruptcy Code.

The amended Plans provide that the claims of Canadian creditors against Philip
Services Corp. will be dealt with in Canada under the CCAA proceedings.  The
amended Canadian Plan also provides that in the event that certain conditions
are not satisfied or Canadian unsecured creditors vote to reject the Canadian
Plan, the Company can implement an alternative means to complete its
restructuring.  Under the alternative structure, the restructuring of Philip
Services Corp. and its Canadian subsidiaries would be accomplished through the
transfer of their businesses as a going concern to one or more direct or
indirect subsidiaries of Philip Services (Delaware), Inc.

Philip's lending syndicate have confirmed their support of the Company's
amended Restructuring Plans.  In addition, the official committee of unsecured
creditors appointed under the Chapter 11 proceedings, have confirmed their
support of Philip's U.S. Plan.  The unsecured creditor committee, which
represents the Company's major unsecured creditors, has urged holders of
unsecured claims to vote in favour of the U.S. Plan.  This is a major step
towards the successful and timely completion of Philip's financial
restructuring.

The Steering Committee of Philip's Syndicate Lenders made the following
statement regarding their ongoing support for Philip Services and the Company's
financial restructuring:

"Our desire is to recover the best return on our investment through a
strengthening of the going concern value of the Company.  This is a long-term,
not a short-term view.  We continue to believe that a restructured Philip
offers the best opportunity to achieve our goal.  This is reflected in the fact
that the lenders have given their full support to the appointment of Anthony
Fernandes as CEO of Philip Services.  We view this as a very positive step for
Philip."

"We want the business to be preserved as a going concern.  We will continue to
work with Philip so that through the Restructuring Plan, or through other
rights available to the lenders, the restructuring of the business can proceed
in a timely manner for the benefit of Philip's employees, its clients and
others, including the lenders."

"We have the full support of our secured lenders for our financial
restructuring and the long term value of our business," said Robert Knauss,
Chairman of Philip's Board of Directors.  "We have addressed the concerns
raised by the Court in the CCAA proceedings and we are well underway with
negotiations to complete our financial reorganization."
