                   PROCEDURE FOR VALUATION OF UNSECURED CLAIMS

SECTION 4.1       AFFECTED UNSECURED CLAIMS
         The Applicants shall on or before the date prescribed in the Creditors'

Affected Unsecured Lender Claims), in order to vote, are required to file
completed Proofs of Claim with the Monitor no later than the Bar Date.

SECTION 4.2       DISALLOWANCES FOR VOTING PURPOSES
         Upon receipt of a completed Proof of Claim, the Applicants shall
accept, revise or reject the amount of the Claim therein set forth for voting
purposes. The Applicants shall, as soon as possible after receipt of a Proof of
Claim but, in any event, no later than the date prescribed in the Creditors'
Meetings Order, or such later date as the Applicants may specify if they have
agreed to accept a Proof of Claim after such date, advise each Creditor in
writing whose Claim has been disallowed in whole or in part for voting purposes
of such disallowance and the reasons therefor (the "Notice of Disallowance").
The Notice of Disallowance will indicate the manner in which a Creditor may
dispute the Applicants' disallowance of its Claim and the address and telecopier
number of the Claims Officer for notification of a dispute. If the Applicants do
not deliver a Notice of Disallowance within the time prescribed above then the
Creditor's Claim shall become an Accepted Claim for Voting Purposes unless
otherwise ordered by the Court, without prejudice to the rights of the
Applicants to disallow the amount of the Claim for other purposes in connection
with this Plan.

SECTION 4.3       DISPUTE NOTICES
         A Creditor who intends to dispute a Notice of Disallowance shall, by
the date prescribed in the Creditors' Meetings Order, notify both the Claims
Officer and the Applicants in writing (the "Dispute Notice") that it does not
accept the Applicants' determination of its Claim (such Claim being a "Disputed
Claim"). A Creditor may accept the amount of the Applicants' determination of
its Claim for voting purposes, in which case the Claim becomes an Accepted Claim
for Voting Purposes, without prejudice to the rights of the Creditor to dispute
the Notice of Disallowance for other purposes in connection with the Plan. Any
Creditor that does not so notify the Claims Officer and the Applicants that it
intends to dispute the Notice of Disallowance by the date prescribed in the
Creditors' Meetings Order, unless otherwise agreed by the Applicants and subject
to any further Order, shall be deemed to have accepted, as final and binding,
the Applicants' determination of its

<PAGE>   18
                                      -17-


Claim for voting purposes. Any notification to the Claims Officer and to the
Applicants pursuant to this Section 4.3 may be effected by facsimile
transmission.

SECTION 4.4       CLAIMS OFFICER TO RESOLVE VOTING DISPUTE
         Upon receipt of a Dispute Notice, the Claims Officer shall attempt to
resolve the dispute between the Applicants and such Creditor, and the Claims
Officer shall, by the date prescribed in the Creditors' Meetings Order or
further Order of the Court, notify the Applicants and such Creditor of the
amount of the Creditor's Claim for voting purposes in which case the Claim as so
determined by the Claims Officer becomes an Accepted Claim for Voting Purposes.

SECTION 4.5       CLAIMS OFFICER TO DETERMINE PROCEDURE
         Subject to the direction of the Court, the Claims Officer shall
determine the manner, if any, in which evidence may be brought before him by the
parties as well as any other procedural matters which may arise in respect of
his determination of a Creditor's Claim.

SECTION 4.6       APPEAL FROM CLAIMS OFFICER TO COURT
         Either a Creditor or the Applicants may, within two (2) Business Days
of notification of the Claims Officer's determination of such Creditor's Claim
in accordance with Section 4.4, appeal such determination to the Court, in
default of which such determination shall, subject to further Order of the
Court, be final and binding on the Applicants and the Creditor.

SECTION 4.7       CLASS CREDITORS' LIST
         The Applicants, at least three Business Days prior to a Creditors'
Meeting, shall establish and maintain a list (the "Class Creditors' List")
setting forth the names and Claims for voting purposes under this Plan of each
Creditor. The Applicants will make the Class Creditors' List available for
inspection at the corporate head office of PSC in Hamilton, Ontario to any
Affected Creditor of the class upon request in writing.

SECTION 4.8         DETERMINATION OF CLAIM FOR PURPOSES OF DISTRIBUTION
         Claims submitted and accepted or determined in accordance with this
Article 4 shall be deemed to be Accepted Claims for Voting Purposes. The
Applicants shall be entitled to dispute the amount of such Claim for purposes
other than voting in accordance with the procedures established in this Section
4.8. The Applicants shall review each Proof of Claim filed pursuant to Section
4.1. In the event the Applicants intend to dispute the amount of such Claim for
any purpose other than voting under the Plan, the Applicants shall, no later
than the date prescribed in the Creditors' Meetings Order, deliver a Notice of
Final Determination to the Creditor which has filed the Proof of Claim stating
the amount that the Applicants have determined to be the proper amount of such
Claim for purposes of

<PAGE>   19
                                      -18-



payments and other distributions under the Plan. Any Creditor receiving a Notice
of Final Determination shall be entitled to apply to the Claims Officer by the
date prescribed in the Creditors' Meetings Order for a summary determination of
the value of the Claim. The Applicants, Creditors and Claims Officer shall
resolve any dispute relating to the value of a Claim using the procedures set
forth in Sections 4.3 to 4.6 for resolving voting disputes, with such changes as

may settle or compromise any Disputed Claim without approval of the Court.

SECTION 4.10      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
Claim unless and until all objections to such Disputed Claim have been settled
or withdrawn or have been determined by Final Order, and the Disputed Claim, or
some portion thereof, has become a Proven Unsecured Claim.

SECTION 4.11      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
distribution an amount of New Unsecured PIK Notes and New Common Shares equal to
100% of distributions (i) to which holders of Disputed Claims would be entitled
under the Plan as of such date if such Disputed Claims were Proven Unsecured
Claims in their Disputed Claim Amount and (ii) to which holders of disputed U.S.
Impaired Unsecured Claims under the U.S. Plan would be entitled if such disputed
U.S. Impaired Unsecured Claims under the U.S. Plan were allowed under the U.S.
Plan in their maximum potential amounts.

SECTION 4.12      DISTRIBUTIONS AFTER DISPUTED CLAIMS RESOLVED
         The Disbursing Agent shall make payments and distributions from the
Disputed Claims Reserve to each holder of a Disputed Claim that has become a
Proven Unsecured Claim in accordance with the provisions of the Plan. On the
next succeeding interim distribution date after the date that the value of the
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 New
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 such
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

<PAGE>   20

each Disputed Claim (i) any remaining New Unsecured PIK Notes and remaining New
Common Shares held in the Disputed Claims Reserve shall be distributed Pro Rata
to holders of Proven Unsecured Claims entitled thereto under the terms of this
Plan and (ii) any other property remaining in the Disputed Claims Reserve shall
become property of the Applicants. 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.

holders of U.S. Impaired Unsecured Claims had such holders voted to accept the
U.S. Plan (based on the Applicants' estimate of the aggregate amount of such
claims), or (iv) if holders of U.S. Impaired Unsecured Claims vote to accept the
U.S. Plan, but the holders of Affected Unsecured Claims vote to reject the Plan,
ninety-one percent (91%) or 21,840,000 common shares of PSC's successor plus an
amount of such common shares equal to the aggregate number of PSC Common Shares
that would have been distributed to the holders of Affected Unsecured Claims
(based on the Applicants' estimate of the proven 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 the holders of Affected Unsecured Claims had such
class voted to accept the Plan (based on the Applicants' estimate of the proven
amount of such claims). If the holders of Proven Unsecured Claims vote to reject
the Plan, the Lenders will have the right to enforce their security over some or
all of the Applicants, with such approvals by the Required Lenders and the
Canadian Court as the Required Lenders may require.

         On the Effective Date, PSC shall record the holders of 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 under the Plan
in favour of each of the matters set forth in Section 6.2(c) hereof.

(2)      Affected Unsecured Claims

         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 an Affected 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) up to US$60
                 million of New Unsecured PIK Notes to be issued pursuant to
                 Article 7 of this Plan and the U.S. Plan and (ii) 327,860,033
                 New Common Shares which shall be five percent (5%) or 1,200,000
                 of the PSC Common Shares issued and outstanding as of the
                 Effective Date, after giving effect to the Stock Consolidation,
                 subject to Dilution (to be shared 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 and benefit of any and all
                 contractual subordination provisions in respect of their
                 Allowed Affected Unsecured Lender Claims; or

(b)              if the holders of Proven 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 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 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.____ per US$1.00.

                 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

         The Plan is premised upon the substantive consolidation of the
Applicants only for purposes of treating 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. On the Effective Date, (a) all guarantees of any
Applicants of the payment, performance or collection of another Applicant with
respect to Affected Unsecured Claims shall be deemed eliminated and cancelled;
(b) any obligation of any Applicant and all guarantees with respect to Affected
Unsecured Claims thereof executed by one or more of the other Applicants shall

and all multiple Affected Unsecured 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
Unsecured Claim of any Applicant shall be deemed filed against the consolidated
Applicants and shall be deemed one Affected Unsecured 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 6.7       ASSUMED INDEMNIFICATION OBLIGATIONS
         The Assumed Indemnification Obligations (other than Excluded
Indemnification Obligations) shall be deemed assumed as of the Effective Date
without any further action by any party.

                                    ARTICLE 7
                       PROVISIONS GOVERNING DISTRIBUTIONS

SECTION 7.1       DISTRIBUTIONS FOR CLAIMS ALLOWED AS OF THE EFFECTIVE DATE
         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 Allowed Affected Secured 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 an Allowed Affected Secured Claim after the
Effective Date shall be made pursuant to Articles 5, 7 and 8 of this Plan.
Notwithstanding the date

<PAGE>   28
                                      -27-


on which any distribution of securities is actually made to a holder of a Claim
that is a Proven Unsecured Claim or an Allowed Affected Secured 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 7.2       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 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 Claim
becomes a Proven Unsecured Claim.

SECTION 7.3       DISTRIBUTIONS BY DISBURSING AGENT
(a)               The Disbursing Agent shall make all distributions required
                  under this Plan (subject to the provisions of Articles 5, 7
                  and 8 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 7.4       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

<PAGE>   29
                                      -28-



which such Person is entitled. Whenever any distribution to a particular Person
would otherwise call for distribution of a fraction of a New Common Share, the
actual distribution of shares shall be rounded to the next higher or lower whole
number as follows: (a) fractions <W063> or greater shall be rounded to the next
higher whole number, and (b) fractions of less than <W063> 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

         Notwithstanding any other provision of the Plan, New Unsecured PIK
Notes will be issued in denominations of US$1,000 and integral multiples
thereof. In the event a Person is entitled to an amount of New Unsecured PIK
Notes that is not an integral multiple of US$1,000, the principal amount of New
Unsecured PIK Notes such holder is entitled to receive shall be rounded to the
nearest integral multiple of US$1,000.

SECTION 7.5       DELIVERY OF DISTRIBUTIONS
         Distributions to holders of Proven Unsecured Claims shall be made by
the Disbursing Agent (a) at the addresses set forth on the Proofs of Claim filed
by such holders or (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. 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.
Amounts in respect of undeliverable distributions made through the Disbursing
Agent, shall be returned to the Applicants until such distributions are claimed.
All claims for undeliverable distributions must be made on or before the second
(2nd) anniversary of the Effective Date, after which date all unclaimed property
shall revert to the Applicants free of any restrictions thereon 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 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 7.6       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



<PAGE>   30
                                      -29-


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 Unsecured Claim that is to receive a
distribution of New Unsecured PIK Notes or Common Shares 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 Unsecured PIK Notes and Common Shares to be distributed pursuant to the Plan
shall, pending the implementation of such arrangements, be treated as an
undeliverable distribution pursuant to Section 7.5.

SECTION 7.7       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 or 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.

SECTION 8.1       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 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 terminate.

         Without limiting the foregoing, all obligations of the Applicants with
respect to Other Equity Securities shall be terminated and cancelled, and the
holders of

<PAGE>   31
                                      -30-


Other Equity Securities shall not be entitled to receive or retain

SECTION 9.1       CONFIRMATION OF PLAN
         Provided that the Plan is approved by the Required Majority of each
Class of Creditors, the Applicants will seek the Confirmation Order (which as
proposed shall be in form and substance acceptable to the Applicants and the
Required Lenders) for the sanction and approval of the Plan. Subject only to the
Confirmation Order being granted and becoming a Final Order in form and
substance reasonably acceptable to the Applicants and the Required Lenders and
the satisfaction of those conditions precedent of the Plan described in Section
9.8, the Plan will be implemented by the Applicants and will be binding upon all
Creditors, holders of Unaffected Obligations and all present and former holders
of claims and interests which are subject to the U.S. Plan.

SECTION 9.2       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 9.3       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 committed
by the Applicants in any covenant, warranty, representation, term, 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, written or oral
and any and all amendments or supplements thereto, existing between such
Creditor and the Applicants and any and all notices of default and demands for
payment under any instrument, including, without limitation any guarantee, shall
be deemed to have been rescinded.

SECTION 9.4       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 9.5       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 9.6       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' Meeting
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 be a part of
and incorporated into the Plan. The Applicants shall give notice by publication
or otherwise to all Creditors in an affected Class of the details of any
modifications or amendments prior to the vote being taken to approve the Plan.
Subject to the consent of the Required Lenders, the Applicants may propose an
alteration or modification to the Plan at any Meeting of Creditors. 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. SECTION 9.7 DEEMING PROVISIONS
         In this Plan, the deeming provisions are not rebuttable and are
conclusive and irrevocable.

SECTION 9.8       CONDITIONS PRECEDENT

whole or in part by the Applicants with the written consent of the Required
Lenders, without any other notice to parties in interest or the Court and
without a hearing. The failure to satisfy or waive any condition to the
Effective Date may be asserted by the Applicants regardless of the circumstances
giving rise to the failure of such condition to be satisfied (including any
action or inaction by a Applicant). The failure of a Applicant 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.

         If, prior to Confirmation, any term or provision of the Plan is held by
the Court to be invalid, void or unenforceable, the Court, at the request of any
Applicant, 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.

omission in connection with, relating to, or arising out of, the CCAA
Proceedings, formulating, negotiating or implementing the Plan or the Lender

property to be distributed under the

<PAGE>   37
                                      -36-


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

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 holders of Lender Claims, 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 PSC in writing, and PSC
may assume the defense thereof, including the employment of counsel reasonably
satisfactory to the Indemnitee, and the payment of all costs and expenses. The

<PAGE>   38
                                      -37-



Indemnitee shall have the right to employ separate counsel in any such claim,
action or proceeding and to consult with PSC in the defense thereof and the fees
and expenses of such counsel shall be at the expense of PSC unless and until PSC
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 PSC in writing that it elects to employ separate counsel at the
expense of PSC, and PSC shall not have the right to assume the defense of such
action or proceeding on behalf of the Indemnitee. In addition, PSC 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 PSC,
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 9.15      BINDING EFFECT
         The Plan shall be binding upon and inure to the benefit of the
Applicants, all present and former holders of Claims, all present and former
holders of Unaffected Obligations, all present and former holders of claims and
interests against PSC which are subject to the U.S.
Plan and their respective successors and assigns.

SECTION 9.16      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. 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 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 9.17      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

<PAGE>   39
                                      -38-


all proceedings taken in connection with this Plan and its provisions shall
be subject to the exclusive jurisdiction of the Court.
