                           STATEMENT ON SCHEDULE 13D

Note:  All information herein with respect to Repap Enterprises Inc., a

         This statement relates to the shares of common stock, no par value
("Common Stock"), of Repap Enterprises Inc.  The address of the principal
executive office of the Issuer is 300 Atlantic Street, Suite 200, Stamford,
Connecticut  06901.

Item 2.  Identity and Background.

         This statement is being filed by (i) Enron Capital & Trade Resources
Corp., a Delaware corporation ("ECT"), whose principal business is the purchase
of natural gas, gas liquids and power through a variety of contractual
arrangements and marketing these energy products to local distribution

production of natural gas and crude oil, the production, purchase,
transportation and worldwide marketing and trading of natural gas liquids,

to herein as the "Reporting Entities."  ECT is a wholly-owned subsidiary of
Enron.

         The address of the principal business office of ECT and Enron is 1400
Smith Street, Houston, Texas 77002.  Schedule I attached hereto sets forth
certain additional information with respect to each director and each executive
officer of ECT and Enron.  The filing of this statement on Schedule 13D shall

Item 3.  Source and Amount of Funds or Other Consideration.

         On May 15, 1998, pursuant to a Purchase Agreement between ECT and the
Issuer (the "Purchase Agreement"), ECT purchased from the Issuer U.S.
$45,000,000 aggregate principal amount of 6% Convertible Subordinated
Debentures due 2005 (the "Debentures") at 100% of such aggregate principal
amount.  The purchase price for such securities was paid in cash, and the
source of funds used for the purchase of the Debentures was working capital on
hand.  See Item 4 for a more complete description of the Debentures and the
transactions contemplated by the Purchase Agreement.

Item 4.  Purpose of Transaction.

         The purchase of the Debentures was the result of a negotiated
transaction with the Issuer.  The Debentures were acquired for investment
purposes.  ECT intends to review its investment in the Issuer on a continuing
basis and, depending upon the price of, and other market conditions relating
to, the Common Stock, subsequent developments affecting the Issuer, the
Issuer's business and prospects, other investment and business opportunities
available to ECT, general stock market and economic conditions, tax
considerations and other factors deemed relevant, may decide to increase or
decrease the size of its investment in the Issuer.

         The Purchase Agreement, the Registration Rights Agreement (as defined
below), the form of Debenture and the Indenture (as defined below), are each
incorporated by reference as exhibits to this statement on Schedule 13D and
incorporated herein by reference, and the following summaries of the terms of
such agreements or instruments are qualified by reference to the actual
agreements or instruments.

         Purchase Agreement.  On May 15, 1998, ECT acquired the Debentures
described in Item 3, pursuant to the Purchase Agreement.  In addition to
providing for the transactions described in Item 3, the Purchase Agreement
provides that at any time following conversion of the Debentures held by ECT
and for so long as ECT holds, directly or indirectly through affiliates or
nominees, at least 13.5% of the Issuer's then issued and outstanding Common
Stock, calculated on a non-diluted basis other than the inclusion in such
calculation of all options granted by the Issuer on or before the date of the
Purchase Agreement, upon ECT's request, the Issuer will permit representatives
of ECT to attend all meetings of the Issuer's Board of Directors and will grant
ECT the reasonable opportunity to be heard at all such meetings of the Board of
Directors with respect to all such matters as may be reasonably considered
relevant to ECT as a holder of Common Stock of the Issuer; and at the first
meeting of shareholders of the Issuer following any such request by ECT, and
for so long as ECT holds, directly or indirectly through affiliates or
nominees, at least 13.5% of the Issuer's then issued and outstanding Common
Stock, at each meeting of shareholders thereafter, management of the Issuer
will nominate for election by the Issuer's shareholders one individual
designated by ECT for election to the Issuer's Board of Directors.






                                 Page 5 of 14
<PAGE>   6

         Registration Rights Agreement.  The Issuer and ECT entered into a
Registration Rights Agreement as of May 15, 1998 (the "Registration Rights
Agreement"), pursuant to which the Issuer agreed to provide certain U.S.
registration rights and Canadian prospectus qualification rights for the shares
of Common Stock issuable upon conversion of the Debentures (the "Shares"), at
the expense of the Issuer.  The record holder of any Shares or Debentures (the
"Holder") has the option to utilize U.S. registration rights and/or Canadian
prospectus qualification rights, and if at the time the Holder exercises a
demand U.S. registration right (whether singularly or in combination with
Canadian prospectus qualification rights) the Issuer is qualified to utilize
the Multijurisdictional Disclosure System implemented in Canada pursuant to
National Policy 45 ("MJDS"), the Issuer will effect such U.S. registration
using MJDS.  The Registration Rights Agreement provides for certain "demand"
and "piggy-back" registration rights.  The Holder can request three demand
registrations and can request to include shares of Common Stock in any
Registration Statement or Canadian Prospectus if the Issuer proposes to
register any securities of the Company entitled to vote generally in the
election of directors (or any securities convertible into or exchangeable for
or exercisable for the purchase of securities so entitled generally to vote in
the election of directors).

         Debentures.  The Debentures mature on June 30, 2005, and on such date,
or on such earlier date the principal amount becomes payable in accordance with
the provisions of the Indenture, the Issuer will pay ECT the sum of U.S.
$45,000,000 and, in the meantime, will pay interest thereon from May 15, 1998
or from the last interest payment date to which interest has been paid or made
available for payment on the Debentures, whichever is later, at the rate of 6%
per annum, on July 15, 1998 and thereafter half-yearly on January 15 and July
15 in each year (unless the Debenture has been previously redeemed in
accordance with the provisions of the Indenture).  The Debentures are
convertible, in whole or in part, at the option of the Holder, at any time
prior to the close of business on the earlier of the business day immediately
preceding June 30, 2005 or, if this Debenture shall be called for redemption,
the business day immediately preceding the date fixed for its redemption, into
fully paid and non-assessable shares of Common Stock (without adjustment for
interest accrued thereon or for any dividends on the Common Stock issuable upon
conversion) at the price of U.S. $0.35 per share, subject to adjustment as set
forth in the Indenture.  All Debentures certified and issued under the
Indenture rank pari passu.  The Debentures are direct obligations of the Issuer
and are not secured by mortgage or other charge.

         The Debentures were issued pursuant to a Trust Indenture between the
Issuer and Montreal Trust Company (the "Trustee") dated as of May 15, 1998 (the
"Indenture").  The Indenture sets forth the terms and conditions upon which the
Debentures are issued and held and the rights of the holders of the Debentures,
of the Issuer and of the Trustee.  The Indenture also sets forth the terms and
conditions for redemption and conversion of the Debentures.  The Debentures
will not be redeemed before the third anniversary of their issuance.  On and
after that date and before maturity, the Debentures are subject to redemption
upon terms set forth in the Indenture, at the Issuer's option, at the principal
amount thereof, plus unpaid interest accrued to the date fixed for






                                 Page 6 of 14
<PAGE>   7
redemption plus any additional amounts to the extent required under the terms
of the Indenture. The aggregate principal amount of Debentures which may be
issued under the Indenture is limited to U.S. $45,000,000 in lawful money of
the United States of America.  The indebtedness evidenced by the Indenture and
the Debentures, including the principal thereof and interest thereon, is
subordinate and junior in right of payment to the prior payment in full of the
Senior Indebtedness (as defined in the Indenture).  The Indenture contains
restrictions on the Issuer's ability to declare or pay any dividend on any of
its shares, to redeem or purchase or make any capital distribution with respect
to any of its shares and to incur additional debt after the date of the
Indenture.

         Other than the transactions described herein, neither of the Reporting
Entities, nor to their knowledge any person listed on Schedule I hereto, has
any plan or proposal that would result in any of the consequences listed in
paragraphs (a) - (j) of Item 4 of Schedule 13D.

Item 5.  Interest in Securities of the Issuer.

         (a)  Neither of the Reporting Entities directly owns any Common Stock.
However, ECT owns Debentures which are convertible into 128,571,429 shares of
Common Stock, subject to adjustment as set forth in the Indenture.  If such
Debentures were converted into Common Stock, the shares of Common Stock
issuable upon conversion of such Debentures would represent approximately 14.7%
of the outstanding Common Stock (based on the number of shares of Common Stock
outstanding as of May 15, 1998 as represented by the Issuer in the Purchase
Agreement).  Enron may be deemed to beneficially own the Debentures held by
ECT.  See Item 2.  Enron disclaims beneficial ownership of any Debentures.

         (b)  ECT and Enron may be deemed to share voting and dispositive power
over the shares of Common Stock issuable upon conversion of the Debentures held
directly by ECT.

         (c)  Other than the transactions described herein, neither of the
Reporting Entities, nor to their knowledge any of the persons named in Schedule
I hereto, has effected any transactions in the Common Stock during the
preceding sixty days.

         (d)  Not applicable.

         (e)  Not applicable.

Item 6.  Contracts, Arrangements, Understandings or Relationships With Respect
         to Securities of the Issuer.

         See the description of the Purchase Agreement, the Debentures, the
Registration Rights Agreement and the Indenture in Item 4 above.

                                  Adverse Effect,

                          (B)     that any Person has given any notice to the

                          taking or proposes to take with respect thereto;

                 (v)      OTHER INFORMATION:  With reasonable promptness, such
                          other information respecting the condition,

                 Together with each delivery of financial statements required
                 by Section 7.6 of the Indenture and Section 4.1(a)(ii) herein,

                 Together with each delivery of financial statements required

                 of any condition or event that then constitutes a Default or
                 an Event of Default, and, if they are aware that any such
                 condition or event then exists, specifying the nature and
                 period of the existence thereof (it being understood that such
                 accountants shall not be liable, directly or indirectly, for
                 any failure to obtain knowledge of any Default or Event of
                 Default unless such auditors should have obtained knowledge
                 thereof in making an audit in accordance with generally
                 accepted auditing standards, or did not make such an audit).

                 The Corporation will, immediately after any Responsible
                 Officer obtains knowledge of an Event of Default or Default,
                 deliver to the Purchaser of a Debenture a written notice
                 specifying the nature and period of existence thereof and what

                 the request of the Purchaser, provide to the Purchaser and to
                 any qualified institutional buyer designated by the Purchaser,
                 such financial and other information as such holder may
                 reasonably determine to be necessary in order to permit
                 compliance with the information requirements of Rule 144A
                 under the Securities Act in connection with the resale of
                 Debentures, except at such times as the Corporation is subject
                 to the reporting requirements of section 13 or 15(d) of the
                 Exchange Act or exempt from such reporting requirements
                 pursuant to Rule 12g3-2(b) of the Exchange Act.  For the

                          its Subsidiaries with the Corporation's officers and
                          (with the consent of the Corporation, which consent
                          will not be unreasonably withheld) its independent
                          chartered accountants, and (with the consent of the
                          Corporation, which consent will not be unreasonably
                          withheld) to visit the other offices and properties
                          of the Corporation and each Subsidiary, all at such

                          and inspect any of the offices or properties of the
                          Corporation or any Subsidiary, to examine all their
                          respective books of account, records, reports and

                          accounts with their respective officers and
                          independent public accountants (and by this provision

                          under Applicable Environmental Laws regarding its
                          property, the absence of which individually or in the
                          aggregate would have a Material Adverse

                          Effect, and comply in all respects with the terms and

                          promulgated or approved thereunder, in each case
                          where failure to do so would individually or in the
                          aggregate have a Material Adverse Effect.

                 (ii)     COPIES OF ENVIRONMENTAL REPORTS:  The Corporation
                          will, promptly upon preparation or receipt thereof,
                          furnish to the Purchaser a copy of any environmental
                          site assessment, environmental impact assessment,
                          disclosure statement or audit report required to be
                          submitted by it or any Subsidiary to any
                          Governmental/Judicial Body in connection with its
                          property where the Corporation or Subsidiary
                          (individually or in the aggregate) could be liable
                          for costs of any clean-up or remedial action
                          associated therewith in excess of U.S.$ 5,000,000,

                          action within such time as may be prescribed by such
                          Governmental/Judicial Body.

                 (iii)    CONTINUOUS RISK MANAGEMENT:  The Corporation will,
                          and will cause each Subsidiary to, maintain a prudent
                          periodic program for proper environmental risk
                          management, including carrying out site inspections
                          and audits and developing contingency plans.

                 (iv)     ENVIRONMENTAL AUDIT:  If the Purchaser determines
                          that the Corporation or a Subsidiary has incurred or
                          may incur any environmental liabilities that could
                          individually or in the aggregate have a Material
                          Adverse Effect, then the Corporation will, or will
                          cause such Subsidiary to, forthwith upon the request
                          of the Purchaser but at the expense of the
                          Corporation or such Subsidiary, undertake a
                          documented, objective review of the Corporation's or
                          such Subsidiary's compliance with Applicable
                          Environmental Laws (an "environmental audit") in
                          respect of the business operations of the Corporation
                          or such Subsidiary affected.  Such environmental
                          audit shall be carried out by an independent
                          environmental consultant or by an employee of the
                          Corporation or Subsidiary with appropriate
                          qualifications and experience, provided that such
                          consultant or employee shall be satisfactory to the
                          Purchaser, acting reasonably, and the Purchaser
                          reserves the right to require that the environmental
                          audit be performed by an independent consultant.  In
                          the conduct of such environmental audit, the
                          consultant or employee shall apply an environmental
                          audit protocol which, in the reasonable opinion of
                          the Purchaser, adequately addresses the scope,

                          methodology and sophistication of the environmental
                          audit. A copy of the environmental audit report shall
                          be provided to the Purchaser immediately upon its
                          completion.

         (e)     PROCEEDS:  The Corporation will as soon as practicable

                 debentures of the Corporation issued pursuant to a trust
                 indenture dated July 14, 1988 (the "1988 Debentures").  The
                 Corporation will, within 10 Business Days after repayment of
                 the 1988 Debentures Closing, provide written confirmation of
                 the redemption and payment in full of the 1988 Debentures,
                 together with other documents verifying the foregoing as the
                 Purchaser may consider necessary.

         (f)     QUARTERLY BUDGET:  As soon as reasonably practicable following
                 approval thereof by its Board of Directors, and in any event
                 within 15 days following the end of each calendar quarter, the
                 Corporation shall deliver to the Purchaser a copy of the
                 Corporation's quarterly capital expenditure and operating
                 budget for the then current quarter.

         (g)     AMALGAMATION:  The Corporation shall make all reasonable
                 commercial efforts to obtain a Certificate of Amalgamation

         (c)     ADDITIONAL COVENANTS.  Upon and following the Amalgamation,
                 the authorizing, declaring, payment or making of Restricted
                 Payments (as defined in the Indenture) by the amalgamated
                 corporation, and the incurrence of Debt by the amalgamated
                 corporation, will be governed by the applicable covenants
                 dealing with the same subject matter (the "Covenants")
                 contained in the indenture (the "New Indenture") governing the
                 securities (the "Securities") to be issued by Repap New
                 Brunswick Inc. ("Repap NB") to finance the redemption of all
                 or any portion of the First Priority Senior Secured Notes of

         If any of the following events (an "Event of Default") shall occur and
be continuing for any reason whatsoever (and whether such occurrence shall be
voluntary or involuntary or come about or be effected by operation of law or
otherwise):

         (a)     INCORRECT REPRESENTATIONS.  Any representation or warranty
                 made by (i) the Corporation herein or in the Indenture, or
                 (ii) the Corporation or any of its officers in any writing
                 furnished in connection with or pursuant to this Agreement,
                 the Indenture or the Debentures, shall be false in any
                 material respect on the date as of which made; or

                                    - 11 -


         (c)     BREACH OF OTHER COVENANT.  The Corporation fails to perform or
                 observe any other agreement, covenant, term or condition
                 contained herein, and such failure shall not be remedied
                 within 30 days after the earlier of the date that (i) a
                 Responsible Officer obtains actual knowledge of such default,
                 and (ii) the Corporation receives notice of such default from
                 the Purchaser; or

         (d)     UNENFORCEABILITY OF DOCUMENTS.  This Agreement, any Debenture,
                 the Indenture or any part thereof, or any material provision
                 of any thereof shall at any time for any reason cease to be in
                 full force and effect, be declared to be void or voidable or
                 shall be repudiated, or the validity or enforceability thereof
                 shall at any time be contested by the Corporation, or the
                 Corporation shall deny that it has any or any further
                 liability or obligation thereunder or any action or proceeding
                 shall be commenced to enjoin or restrain the performance or
                 observance by the Corporation of any material terms thereof or
                 to question the validity or enforceability thereof, or at any
                 time it shall be unlawful or impossible for the Corporation to
                 perform any of its obligations thereunder if any such event,
                 circumstance or condition could reasonably be expected to have
                 a Material Adverse Effect; or

         (e)     CROSS DEFAULT.  There occurs an Event of Default, as defined
                 in the Indenture.

The Purchaser may at its option, by notice in writing to the Corporation,
require the Corporation to repurchase all or any of the Debentures then held by
the Purchaser pursuant to section 4.6 of the Indenture and provided further
that the Purchaser shall be entitled to receive the percentage of principal
amount applicable to redemptions of Debentures as set forth in section 4.1 of
the Indenture for all repurchases pursuant to this section in respect of Events
of Default occurring on or after July 1, 2001 or the percentage of principal
amount specified in section 4.8 of the Indenture for all repurchases pursuant
to this section in respect of Events of Default occurring after the date hereof
and prior to July 1, 2001.  Notwithstanding the foregoing, if an Event of
Default described in section 8.1(i) or section 8.1(j) of the Indenture has
occurred and is continuing, the Corporation may cure such event of default as
set forth in section 8.9 of the Indenture.

The Corporation acknowledges, and the parties hereto agree, that the Purchaser
has the right to maintain its investment in the Debentures free from repayment
by the Corporation (except as specifically provided for herein or in the
Indenture) and that the provision for payment of any amount in excess of the
principal amount of a Debenture, by the Corporation, in the event that the
Debentures are repurchased or are accelerated as a result of an Event of
Default, is intended to provide compensation for the deprivation of such right
under such circumstances.

7.1      REPRESENTATIONS, COVENANTS AND WARRANTIES

         The Corporation represents, covenants and warrants as follows:

         (a)     ORGANIZATION. The Corporation is a corporation duly
                 incorporated and validly existing in good standing under the

                 validly existing in good standing under the laws of the
                 jurisdiction in which it is incorporated or formed. The
                 Corporation is validly registered as an extra-provincial
                 corporation under the laws of each jurisdiction in which it
                 carries on a material business or owns material property. Each
                 Subsidiary is validly registered in each jurisdiction in which
                 it carries on a material business or owns material property.
                 The execution, delivery and performance by the Corporation of
                 this Agreement, the Indenture and the Debentures are within the
                 Corporation's corporate powers and have been duly authorized by
                 all necessary corporate action. This Agreement, the Indenture
                 and the Debentures constitute legal, valid and binding
                 obligations of the Corporation enforceable against it in
                 accordance with their respective terms, except as such
                 enforceability may be limited by (i) applicable bankruptcy,
                 insolvency, reorganization, moratorium or other similar laws
                 affecting the enforcement of creditors' rights generally and
                 (ii) general principles of equity (regardless of whether such
                 enforceability is considered in a proceeding in equity or at
                 law). All of the Subsidiaries of the Corporation, their past
                 and present corporate names, the percentage direct or indirect

                 confirmation of whether at the date of this Agreement a
                 Subsidiary is material to the business, financial position or
                 operations of the Corporation, by virtue of owning or holding
                 assets constituting more than 5% of the consolidated assets of
                 the Corporation, or revenues constituting more than 5% of the
                 consolidated revenues of the Corporation, or in respect of
                 which the Corporation has material obligations or liabilities
                 whether actual or contingent, are listed in Schedule D.

         (b)     FINANCIAL STATEMENTS.  The Corporation has furnished the
                 Purchaser with the following financial statements: (i) an
                 audited consolidated balance sheet of the Corporation as at

                 financial statements (including any related schedules) are
                 true and correct in all material respects (subject, as to
                 interim statements, to changes resulting from audits and
                 year-end adjustments), have been prepared in accordance with
                 GAAP consistently followed throughout the periods involved and

                 Corporation and its Subsidiaries required to be shown in
                 accordance with GAAP.  The consolidated balance sheets present
                 fairly the financial position of the Corporation and its
                 Subsidiaries as at the dates thereof, and the statements of
                 operations and changes in financial position present fairly
                 the results of the operations of the Corporation and its
                 Subsidiaries and their changes in financial position for the
                 periods indicated.  There has been no material adverse change
                 in the business, condition (financial otherwise), operations
                 or business prospects of the Corporation and its Subsidiaries
                 taken as a whole since December 31, 1997.

         (c)     ACTIONS PENDING.  There is no action, suit, investigation or
                 proceeding pending, to the knowledge of the Corporation,
                 threatened against the Corporation or any of its Subsidiaries,
                 or any properties or rights of the Corporation or any of its
                 Subsidiaries, by or before any Governmental/Judicial Body
                 which, individually or in the aggregate, could have a Material
                 Adverse Effect other than the New Brunswick action R. v. Paul.
                 There is no action, suit, investigation or proceeding pending
                 or, to the knowledge of the Corporation, threatened against
                 the Corporation or any of its Subsidiaries which purports to
                 affect the validity or enforceability of this Agreement, the
                 Indenture or any Debenture.

         (d)     OUTSTANDING DEBT.  Neither the Corporation nor any of its
                 Subsidiaries has outstanding any material Debt except for Debt
                 included in Schedule E, together with particulars thereof.
                 There exists no default or event of default under the
                 provisions of any instrument evidencing such Debt or of any
                 agreement relating thereto.

         (e)     TITLE TO PROPERTIES.  Subject to minor encumbrances which in
                 aggregate will not prevent the Corporation and its
                 Subsidiaries from having normal use and enjoyment of their
                 respective properties, the Corporation and each of its
                 Subsidiaries has good and indefeasible title to its real
                 property, and good and valid title to all of its other
                 respective properties and assets, including the properties and
                 assets reflected in the audited balance sheet as at December
                 31, 1997 referred to in Section 7.1(b) (other than properties
                 and assets disposed of in the ordinary course of business).

                 Corporation and its Subsidiaries are as set forth in Schedule

                 Corporation and its Subsidiaries are valid and subsisting and
                 are in full force and effect.

         (f)     TAXES.  The Corporation and each of its Subsidiaries have
                 filed all Canadian and U.S. federal, provincial, state and
                 other income tax returns which are required to be filed, and
                 each has paid all taxes as shown on such returns and on all
                 assessments received by it to the extent that such taxes have
                 become due, except such taxes as are being contested in good
                 faith by appropriate proceedings and for which adequate
                 reserves have been established in the reasonable opinion of
                 the Corporation and in accordance with GAAP.

                 Debentures or the common shares of the Corporation issuable on
                 conversion of the Debentures, nor fulfilment of nor compliance
                 with the terms and provisions hereof, of the Indenture and the
                 Debentures will conflict with, or result in a breach of the
                 terms, conditions or provisions of, or constitute a default
                 under, or result in any violation of, or result in the
                 creation of any Lien upon any of the properties or assets of
                 the Corporation or any of its Subsidiaries, or trigger any
                 "change-of-control" provision, rights plan or similar
                 provision, pursuant to the articles, by-laws or any unanimous
                 shareholders agreement or declaration of the Corporation or
                 any of its Subsidiaries, any Applicable Law or any agreement
                 (including any agreement with shareholders), to which the
                 Corporation or any of its Subsidiaries is subject.  The
                 Corporation and its Subsidiaries are in compliance with
                 Applicable Laws where failure to do so would individually or
                 in the aggregate have a Material Adverse Effect.  Neither the
                 Corporation nor any of its Subsidiaries is a party to, or
                 otherwise subject to any provision contained in, its articles,
                 any instrument evidencing Indebtedness of the Corporation or
                 such Subsidiary, any agreement relating thereto or any other
                 contract or agreement which limits the amount of, or otherwise
                 imposes restrictions on the incurring of, Debt of the
                 Corporation of the type to be evidenced by the Debentures
                 except as set forth in the agreements listed in Schedule G.

         (h)     PRIVATE OFFERING OF DEBENTURES.  Neither the Corporation nor
                 any agent acting on its behalf has, directly or indirectly,
                 offered the Debentures or any similar security of the
                 Corporation for sale to, or solicited any offers to buy the
                 Debentures or any similar security of the Corporation from, or
                 otherwise approached or negotiated with respect thereto with,
                 any Person other than not more than 150 institutional
                 "accredited investors" (within the meaning of Rule 501(a)(1),
                 (2), (3) or (7) of the Securities Act), and neither the
                 Corporation nor any agent acting on its behalf has taken or
                 will take any action which would subject the issuance or sale
                 of the Debentures to the provisions of Section 5 of the
                 Securities Act or to the registration, qualification or
                 similar provisions of any securities or

                 "blue sky" laws of any applicable jurisdiction or result in any
                 contravention of the provisions of any securities law of any
                 applicable jurisdiction.

         (i)     USE OF PROCEEDS. Neither the Corporation nor any Subsidiary has
                 any present intention of acquiring any "margin stock" as
                 defined in Regulation U (12 CFR Part 221) of the Board of
                 Governors of the United States Federal Reserve System ("margin
                 stock"). The proceeds of sale of the Debentures will be used as
                 set forth in Section 4.1(e). None of such proceeds will be
                 used, directly or indirectly, for the purpose of buying or
                 carrying any margin stock or for the purpose of maintaining,
                 reducing or retiring any Indebtedness which was originally
                 incurred to purchase or carry any stock that is currently a
                 margin stock or for any other purpose which might constitute
                 this transaction a "purpose credit" within the meaning of such
                 Regulation U or for the purpose of buying or carrying or
                 trading in any securities under such circumstances as to
                 involve the Corporation or any Subsidiary in a violation of
                 Regulation X of said Board (12 CFR Part 224) or to involve any
                 broker or dealer in a violation of Regulation T of said Board
                 (12 CFR Part 220). Neither the Corporation nor any agent acting
                 on its behalf has taken or will take any action which might
                 cause this Agreement or the Debentures to violate Regulation T,
                 Regulation U, Regulation X or any other regulation of the Board
                 of Governors of the United States Federal Reserve System or to
                 violate the Exchange Act, in each case as in effect now or as
                 the same may hereafter be in effect.

         (j)     GOVERNMENTAL CONSENT.  Neither the nature of the Corporation
                 or of any Subsidiary, nor any of their respective businesses
                 or properties, nor any relationship between the Corporation or
                 any Subsidiary and any other Person, nor any circumstance in
                 connection with the offering, issuance, sale or delivery of
                 the Debentures or the issuance of common shares of the
                 Corporation on conversion of the Debentures is such as to
                 require any authorization, consent, approval, exemption or
                 other action by or notice to or filing with any
                 Governmental/Judicial Body (other than routine filings after
                 the Date of Closing with the applicable provincial securities
                 regulatory authorities and stock exchanges) in connection with
                 the execution and delivery of this Agreement, the Debentures
                 or the Indenture, the offering, issuance, sale or delivery of
                 the Debentures or the issuance of common shares of the
                 Corporation on conversion of the Debentures or fulfilment of
                 or compliance with the terms and provisions hereof, of the
                 Indenture or of the Debentures.

         (k)     ENVIRONMENTAL COMPLIANCE.  Except where individually or in the
                 aggregate no Material Adverse Effect could reasonably be
                 expected to result therefrom, and except as disclosed in the
                 Corporation's Annual Report on Form 10-K  (the "10-K") for the
                 fiscal year ended December 31, 1997 as filed with the SEC:

                                  7.1(k)(i)(a)(C),

                                           Adverse Effect, or

                                  (2)      has been fully remedied or satisfied
                                           in compliance with Applicable Laws,

         (m)     ENVIRONMENTAL RISK MANAGEMENT.  The Corporation and each
                 Subsidiary have implemented and are now maintaining a prudent
                 periodic program for environmental risk management.

         (n)     DISCLOSURE.  Neither this Agreement (insofar as it makes
                 statements concerning the Corporation, its Subsidiaries and
                 their respective businesses and affairs), nor any other
                 document, certificate or statement furnished to any Purchaser
                 by the Corporation or its agents in connection herewith
                 contains any untrue statement of a material fact or omits to
                 state a material fact necessary in order to make the
                 statements contained herein or therein not misleading.  To the
                 knowledge of the Corporation, there is no fact or facts
                 peculiar to the Corporation or any of its Subsidiaries
                 (excluding conditions general to the industries in which they
                 carry on business) which individually or in the aggregate
                 materially adversely affects or in the future may (so far as
                 the Corporation can now foresee) materially adversely affect
                 the business, property or assets, or financial condition of
                 the Corporation or any of its Subsidiaries taken as a whole
                 which has not been set forth in this Agreement or in the other
                 documents, certificates and statements furnished to each
                 Purchaser by or on behalf of the Corporation prior to the date
                 hereof in connection with the transactions contemplated
                 hereby.  The materials comprising the Public Record contain
                 all required disclosure under applicable securities laws,
                 including under the Securities Act (Ontario), the United
                 States Securities Exchange Act of 1934, as amended, and the
                 United States
                 Securities Act of 1933, as amended, and such materials include
                 complete and accurate disclosure of the matters set forth
                 therein at the time such disclosure was made.

         (o)     PENSION ASSETS.  Since December 31, 1997 there has been no
                 material change in the value of pension assets attributable to
                 the pension plans of the Corporation and its Subsidiaries as
                 set forth in note 21 to the audited consolidated financial
                 statements of the Corporation dated December 31, 1997 and each
                 defined benefit or defined contribution pension plan of the
                 Corporation or its Subsidiaries is currently in a surplus
                 position.

         (p)     FOREIGN ASSETS CONTROL REGULATIONS, ETC.  The Corporation is
                 not a "national" of any foreign country with which the United
                 States of America maintains a commercial embargo, or an order
                 freezing assets, pursuant to legislation, Executive orders of
                 the President, or regulations of the Treasury Department.
                 Neither the sale of the Debentures by the Corporation nor the
                 use of the proceeds thereof by the Corporation will violate
                 any of such legislation, regulations or orders.

         (q)     INVESTMENT COMPANY ACT AND PUBLIC UTILITY HOLDING COMPANY
                 STATUS.  The Corporation is not (i) an investment company or a
                 Person directly or indirectly controlled by or acting on

10.9     DESCRIPTIVE HEADINGS

         The descriptive headings of the several Sections of this Agreement are
inserted for convenience only and do not constitute a part of this Agreement.

10.10    COUNTERPARTS

         This Agreement may be executed in any number of counterparts, and by
facsimile, all of which together shall constitute one instrument.

10.11    JUDGMENT CURRENCY

         (a)     If for the purposes of obtaining judgment in any court it
                 becomes necessary to convert any amount due hereunder in one
                 currency into another currency, then the conversion shall be
                 made at the Rate of Exchange prevailing on the last Business
                 Day before the day on which
                 the judgment is given.  "Rate of Exchange" means the rate at
                 which the holder is able on the relevant date to purchase the
                 currency being converted for such other currency.

         (b)     In the event that there is a change in the Rate of Exchange
                 prevailing between the Business Day before the day on which
                 the judgment is given and the date of payment, the Corporation
                 will pay such additional amount (if any) or, as the case may
                 be, the holder will refund such amount (if any) as may be
                 necessary to ensure that the amount paid on such date is the
                 amount in such other currency which, when converted at the
                 Rate of Exchange prevailing on the date of payment, is the
                 amount then due under this Agreement in the currency which was
                 converted.

         (c)     Any amount due from the Corporation or any holder pursuant to
                 this Section will be due as a separate debt and shall not be
                 affected by judgment being obtained for any other sum due
                 under or in respect of this Agreement or any Debenture.

         (d)     The Corporation shall indemnify each holder against payment by
                 the holder of any premiums and costs of exchange incurred in
                 connection with the purchase of, or conversion into, the
                 relevant currency.

         (d)     A reference in this Agreement to the equivalent of one
                 currency in another currency shall mean the equivalent
                 determined using the noon spot rate of exchange for conversion
                 announced by the Bank of Canada on the day for conversion.

                 Corporation or any Subsidiary with Applicable Environmental
                 Laws;

         (c)     the imposition or assertion of any Lien including any expenses
                 collectable as taxes affecting their property under Applicable
                 Environmental Laws by any Governmental/Judicial Body;

         (d)     any claim asserted or order issued by a Governmental/Judicial

                 the activities or omissions of the Corporation or its
                 Subsidiaries); or

         (e)     any non-compliance with any provision herein relating to

         Without limiting the generality of the foregoing, the indemnities in
this Section shall extend to:

         (a)     reasonable legal fees on a solicitor and his own client basis,
                 including the reasonable costs of defending and/or
                 counterclaiming or claiming over against third parties in
                 respect of any action or matters; and

         (b)     any amounts payable arising out of a settlement of any action
                 entered into between the Purchaser, acting reasonably, and any
                 Person with the consent of the Corporation (which consent will
                 not be unreasonably withheld);

but shall not extend to any claim, liability or obligation to the extent the
same relates to a decrease in the value of Debentures or arises solely due to
the gross negligence or wilful misconduct of the holder claiming
indemnification.

         These indemnities shall extend to the officers, directors, employees,
shareholders, agents and assignees of the Purchaser, and the Corporation will
hold the benefit of these indemnities in trust for such indemnified parties to

or other transfer from the Purchaser holds not less than U.S.$10,000,000

rights and entitlements under the indemnity granted by the Corporation in this
Section 10.13 as if such Person was a party to this Agreement.

Purchaser and for so long as the Purchaser holds, directly or indirectly
through affiliates or nominees, at least 13.5% of the Corporation's then issued
and outstanding common shares, calculated on a non-diluted basis other than the
inclusion in such calculation of all options granted by the Corporation on or
before the date of this Agreement, upon the Purchaser's request:

         (a)     the Corporation will permit representatives of the Purchaser
                 to attend all meetings of the Corporation's Board of Directors
                 whether convened by telephone or otherwise, and will provide

<PAGE>   38
                                    - 35 -


                 concurrent with such notice being given to the Board of
                 Directors, and will grant the Purchaser the reasonable
                 opportunity to be heard at all such meetings of the Board of
                 Directors with respect to all such matters as may be reasonably
                 considered relevant to the Purchaser as a holder of common
                 shares of the Corporation; and

         (b)     at the first meeting of shareholders of the Corporation
                 following any such request by the Purchaser, and at each
                 meeting of shareholders thereafter, management of the
                 Corporation will nominate for election by the Corporation's
                 shareholders one individual designated by the Purchaser for
                 election to the Corporation's Board of Directors.

financial statements as required by Section 4.1 or the annual audited financial
statements as required by Article 7 of the Indenture, at least 15 days notice
shall be given by the Purchaser to the Corporation setting forth the time and

10.16    ADJUSTMENTS TO CONVERSION PRICE

         (a)     The provisions of section 5.5(2) of the Indenture and the
                 other provisions of article 5 of the Indenture applicable
                 thereto, shall also apply to all options to subscribe for
                 common shares of the Corporation and to all rights to
                 subscribe for securities exchangeable for or convertible into
                 common shares of the Corporation, granted to employees,
                 officers and directors of the Corporation pursuant to any
                 benefit or compensation plan of the Corporation in effect from
                 time to time but not including common shares of the
                 Corporation currently reserved for issuance on exercise of any
                 options under any such plans in effect on the date hereof, and
                 in each such case the Conversion Price (as defined and applied
                 in the Indenture), applicable only to the Debentures held by
                 the Purchaser, shall be deemed to be adjusted as set forth in
                 section 5.5(2)(a) and (b) of the Indenture.  After any such
                 deemed adjustment, and upon any conversion of Debentures by
                 the Purchaser the Corporation shall, in addition to and
                 concurrently with receipt of the common shares of the
                 Corporation which it is entitled to receive  pursuant to the
                 provisions of the Indenture, receive such additional common
                 shares of the Corporation as are required to give effect to
                 the deemed adjustment to the 

<PAGE>   39
                                    - 36 -


                 Conversion Price set forth above. Further, any adjustments to
                 the Conversion Price pursuant to section 5.5 of the Indenture
                 shall apply to the Conversion Price as adjusted herein from
                 time to time.

         (b)     In addition to the right in Section 10.16(a), the Purchaser
                 shall be entitled to participate pro rata in:

                 (i)      any issuances of common shares from treasury by way
                          of private placement or otherwise, and

                 (ii)     any issuances of rights, warrants or other securities
                          convertible into common shares,

                 to other than all or substantially all existing shareholders
                 of the Corporation.

                 The pro rata participation by the Purchaser shall be effected
                 by way of sales by the Corporation to the Purchaser as part of
                 a public distribution or private placement of the relevant
                 securities (in accordance with available exemptions from
                 prospectus filing requirements, if applicable) to the
                 Purchaser of a sufficient number of common shares so as to
                 effect such pro rata participation as determined in paragraph
                 (c) below, at either the public distribution offering price or
                 the private placement offering price for such securities, as
                 applicable.

         (c)     In calculating the number of common shares required to be
                 issued by the Corporation to the Purchaser to satisfy the pro
                 rata participation right described in (b) above, such number
                 shall be determined by reference to the percentage of common
                 shares of the Corporation then owned by the Purchaser as a
                 result of, or acquirable by the Purchaser upon, a conversion
                 of Debentures, relative to all common shares of the
                 Corporation then outstanding determined immediately prior to
                 any of the events triggering such participation rights as
                 described above.

10.17    FURTHER ASSURANCES

         Each party shall promptly cure any defect by it in the execution and
delivery of this Agreement.  The Corporation, at its expense, shall promptly
execute and deliver to the Purchaser, upon the reasonable request by the
Purchaser in writing, all such other and further documents, agreements,

         (a)     MEDIATION.  If a dispute arises out of or is related to this
                 Agreement or the breach thereof (a "Demand"), the parties
                 agree to first attempt, in good faith, to settle the Demand by
                 mediation under the Commercial Mediation Rules of the American
                 Arbitration Association ("AAA") before resorting to binding
                 arbitration as set forth in this Section 10.18. If the parties
                 are unable to resolve the matter within one calendar month of
                 one party giving notice to the other party hereto requesting
                 mediation in accordance with this Section 10.18, then any
                 remaining unresolved controversy, claim or dispute arising out
                 of or relating to this Agreement or the breach thereof, shall
                 be settled by binding arbitration in accordance with this
                 Section 10.18.

         (b)     APPLICABLE LAW.  All questions concerning the validity,
                 interpretation, performance or breach of this Agreement shall
                 be governed and decided by the laws in force from time to time
                 in the State of New York.

                 on the date of this Agreement (the "Rules").  In the event of
                 any conflict between the Rules and this Section 10.18, the
                 provisions of this Section 10.18 shall govern.

         (d)     ARBITRATORS. Each party shall appoint one arbitrator within 30

                 arbitrators appointed by the parties shall, within 30 days
                 after their appointment, appoint a third presiding arbitrator.
                 If either party fails to nominate an arbitrator, or the two
                 arbitrators appointed by the parties are unable to appoint a
                 presiding arbitrator within the stated periods, the second or
                 presiding arbitrator, as the case may be, shall be appointed
                 according to the procedures of Rule 13 of the Rules. All
                 arbitrators shall be fluent in English, and all hearings shall

         (e)     AWARD.  The arbitrators shall, by majority vote, render a
                 written decision stating reasons therefor within 60 days after
                 the respondent receives the Demand.  Any cash award shall be
                 payable in lawful currency of the United States of America
                 through a branch of a bank located in New York, New York net

                 own costs of the arbitration unless awarded otherwise by the
                 arbitrators.

         (f)     ENFORCEMENT.  The award shall be final and enforceable and may
                 be confirmed by the judgment of a court of competent
                 jurisdiction.

order to provide Shareholder with necessary marketing flexibility for
dispositions of Shares: i) Shareholder will have the option to utilize the U.S.
registration rights and/or the Canadian prospectus qualification rights on the
terms set forth herein, and ii) if at the time Shareholder exercises a demand
U.S. registration right (whether singularly or in combination with Canadian
prospectus qualification rights) the Company is qualified to utilize the

Policy 45 ("MJDS"), the Company shall effect such U.S. registration using MJDS.

                           prospectus as described in (ii) above, in respect of;

                  all or any portion (provided that such portion represents at
                  least 22% of all of the Registrable Securities at the date
                  hereof) of the Registrable Securities that are held by such
                  Holder or Holders (collectively, the "Requesting Holder") for
                  sale in the manner specified in the Request Notice.

         (b)      Following receipt of a Request Notice, the Company shall
                  promptly notify each Holder (except the Requesting Holder) of
                  the receipt of a Request Notice and shall use its best efforts
                  to

                  (i)      file a registration statement under the Securities
                           Act (each such registration statement is hereinafter
                           referred to as a "Registration Statement") effecting
                           the registration under the Securities Act;

                  (ii)     file a preliminary short form prospectus in all
                           provinces of Canada (each such preliminary short form
                           prospectus is hereinafter referred to as a "Canadian
                           Prospectus") qualifying the relevant Registrable
                           Securities; or

                  (iii)    file both a Registration Statement and a Canadian
                           Prospectus as described in (i) and (ii) above;

                  for public sale in accordance with the method of disposition
                  specified in such Request Notice, the Registrable Securities
                  specified in the Request Notice (and in any notices received
                  from other Holders no later than the 15th day after receipt of
                  the notice sent by the Company) (such other Holders and the
                  Requesting Holder are hereinafter referred to as the
                  "Requesting Holders"). If such method of disposition shall be
                  an underwritten public offering, the Company may designate the
                  managing underwriter of such offering, subject to the approval
                  of the Requesting Holders holding a majority of the
                  Registrable Securities to be registered, which approval shall
                  not be withheld unreasonably.

         (c)      The Company shall be obligated to register (pursuant to
                  Section 2.1(b)(i)), file a qualifying prospectus in respect of
                  Registrable Securities (pursuant to Section 2.1(b)(ii)), or
                  register and file a qualifying prospectus (pursuant to Section
                  2.1(b)(iii)), on three occasions only. 

                  A request pursuant to Section 2.1(a)(i), (ii) or (iii) shall
                  be counted as one of the three required registrations,
                  prospectus filings or combined registration and prospectus
                  filings only when (i) all the Registrable Securities requested
                  to be included in any such registration or prospectus filing

                                      - 4 -



                  have been so included, (ii) the corresponding Registration
                  Statement has become effective under the Securities Act,
                  and/or a receipt for a final prospectus has been issued by the
                  Ontario Securities Commission, as applicable, and (iii) the
                  public offering has been consummated and the Registrable
                  Securities have been sold on the terms and conditions
                  specified therein unless the offering is not consummated or
                  any Registrable Securities have not been sold as a result of a
                  default by a Requesting Holder or any underwriter or the
                  Company shall have no further obligation pursuant to Section
                  2.3(g).

         (d)      The Company shall be entitled to include in any Registration
                  Statement or Canadian Prospectus filed pursuant to this
                  Section 2.1, for sale in accordance with the method of
                  disposition specified by the Requesting Holder, securities of
                  the Company entitled to vote generally in the election of
                  directors (or any securities convertible into or exchangeable
                  for or exercisable for the purchase of securities so entitled
                  generally to vote in the election of directors) (collectively,
                  "Voting Securities") to be sold by the Company for its own
                  account, except as and to the extent that, in the opinion of
                  the managing underwriter (if such method of disposition shall
                  be an underwritten public offering), such inclusion would
                  materially jeopardize the successful marketing of the
                  Registrable Securities to be sold. Any Person other than a
                  Holder entitled to piggy-back registration rights with respect
                  to a Registration Statement or Canadian Prospectus filed
                  pursuant to this Section 2.1 may include Voting Securities of
                  the Company with respect to which such rights apply in such
                  Registration Statement or Canadian Prospectus for sale in
                  accordance with the method of disposition specified by the
                  Requesting Holder, except and to the extent that, in the
                  opinion of the managing underwriter (if such method of
                  disposition shall be an underwritten public offering) such
                  inclusion would materially jeopardize the successful marketing
                  of the Registrable Securities to be sold. Except as provided
                  in this subsection (d), the Company will not effect any other
                  registration, or file a preliminary prospectus in respect of,
                  its Voting Securities (except with respect to Registration
                  Statements on Form S-4 or S-8, or the equivalent form for
                  foreign private issuers, for purposes permissible under such
                  forms as of the date hereof), whether for its own account or
                  that of any other security holder, from the date of receipt of
                  a Request Notice requesting the registration of or prospectus
                  filing in respect of a firm commitment underwritten public
                  offering until the completion of the distribution by the
                  underwriters of all securities thereunder.

         (e)      Until no Registrable Securities remain outstanding, the
                  Company shall not issue any demand registration rights or
                  Canadian prospectus qualification rights to any person or
                  entity without the prior written consent of Shareholder, which
                  consent


<PAGE>   5

                                      - 5 -


                  shall not be unreasonably withheld, provided always that 
                  notwithstanding any such issue Shareholder shall remain
                  entitled to exercise the registration rights as set forth in
                  Section 2.2 in respect of a demand registration or prospectus
                  qualification by any such person or entity and demand
                  registration rights as set forth in Section 2.1.

2.2      Piggy-Back Registration.

         If the Company proposes to register any Voting Securities under the
Securities Act for sale to the public for cash or to file with one or more
Canadian provincial securities commissions a preliminary prospectus relating to
an offering of Voting Securities for sale to the public for cash, whether for
its own account or for the account of other security holders or both (except
with respect to Registration Statements on Forms S-4 or S-8 for purposes
permissible under such forms as of the date hereof), each such time it will give
written notice to all Holders of its intention to do so no less than 20 days
prior to the anticipated filing date. Upon the written request of any Holder,
received by the Company no later than the 10th day after receipt by such Holder
of the notice sent by the Company, to register or include in the securities
offered by the preliminary prospectus, on the same terms and conditions as the
securities otherwise being sold pursuant to such registration or preliminary
prospectus, any of its Registrable Securities (which request shall state the
intended method of disposition thereof), the Company will use its best efforts
to cause the Registrable Securities as to which such request relates to be
included in the securities to be covered by the Registration Statement or
preliminary prospectus proposed to be filed by the Company, on the same terms
and conditions as any similar securities included therein, all to the extent
requisite to permit the sale or other disposition by each Holder (in accordance
with its written request) of such Registrable Securities; provided, however,
that the Company may at any time prior to the effectiveness of any such
Registration Statement or the filing of a final prospectus, in its sole
discretion and without the consent of any Holder, abandon the proposed offering
in which any Holder had requested to participate. The number of Registrable
Securities to be included in such a registration statement or preliminary
prospectus may be reduced or eliminated if and to the extent that, in the case
of an underwritten offering, in the opinion of the managing underwriter such
inclusion would materially jeopardize the successful marketing of the securities
(including the Registrable Securities) proposed to be sold therein; provided,
however, that such number of Registrable Securities shall not be reduced if any
securities included in such registration are included other than for the account
of the Company. From and after the date of this Agreement and until no
Registrable Securities remain outstanding, the Company shall not grant any
piggy-back registration rights to any Person unless such rights are expressly
made subject to the prior right of Holders to include any or all of their
Registrable Securities before such other Person includes any shares in any
registration statement or preliminary prospectus relating to an underwritten
public offering with respect to which, in the opinion of the managing
underwriter, the inclusion in the offering of all shares requested to be
registered or included in the preliminary prospectus by all Persons holding
registration rights would materially jeopardize the




<PAGE>   6


                                      - 6 -


successful marketing of the securities (including the Registrable Securities) to
be sold. In the event that the number of Registrable Securities to be included
in a registration statement or preliminary prospectus is to be reduced as
provided above, within 10 days after receipt by each Holder proposing to sell
Registrable Securities pursuant to the offering of the opinion of such managing
underwriter, all such Selling Holders may allocate among themselves the number
of shares of such Registrable Securities which such opinion states may be
distributed without adversely affecting the distribution of the securities
covered by the Registration Statement or the preliminary prospectus, and if such
Holders are unable to agree among themselves with respect to such allocation,
such allocation shall be made in proportion to the respective numbers of shares
specified in their respective written requests.

2.3      Registration and Prospectus Filing Procedures.

         If and whenever the Company is required pursuant to this Agreement to
effect the registration of any of the Registrable Securities, the Company will,
as expeditiously as possible:

         (a)      following each receipt of a Request Notice pursuant to section
                  2.1(a):

                  (i)      prepare, file with and obtain a receipt from the
                           securities commissions in all provinces of Canada:

                           (I)      a preliminary short form prospectus relating
                                    to such securities (which filing shall be
                                    made within 45 days after the receipt by the
                                    Company of a Request Notice) and use its
                                    best efforts to cause such preliminary
                                    prospectus to be cleared for filing of a
                                    final prospectus; and

                           (II)     a final short form prospectus relating to 
                                    such securities; or

                  (ii)     prepare and file with

                           (I)      the Commission a Registration Statement, on
                                    a form available to the Company, with
                                    respect to such securities (which filing
                                    shall be made within 45 days after the
                                    receipt by the Company of a Request Notice)
                                    and use its best efforts to cause such
                                    Registration Statement to become and remain
                                    effective for the period of the distribution
                                    contemplated thereby (determined pursuant to
                                    subparagraph 2.3(g) below); and

                                      - 7 -


                           (II)     file with the Commission such amendments and
                                    supplements to such Registration Statement
                                    and the prospectus used in connection
                                    therewith as may be necessary to keep such
                                    Registration Statement effective for the
                                    period specified in subsection (g) below
                                    and as may be necessary to comply with the
                                    provisions of the Securities Act with
                                    respect to the disposition of all
                                    securities covered by such Registration
                                    Statement in accordance with the sellers'
                                    intended method of disposition set forth in
                                    such Registration Statement for such
                                    period; or 

                  (iii)    prepare and file the prospectuses and registration
                           statement (including amendments and supplements) as
                           described in subsections (a) and (b) above;

                  in accordance with the instructions set forth in the Request 
                  Notice.

                  Provided, however, that, if the Company is in possession of
                  material information that has not been disclosed to the public
                  and the Company reasonably deems it to be advisable not to
                  disclose such information in a registration statement or a
                  Canadian Prospectus, then the period after the receipt by the
                  Company of a Request Notice in which it must comply with this
                  Section 2.3(a) shall be extended for such time (but in no case
                  longer than 90 days commencing on the date of receipt by the

                  prospectus or the Registration Statement or supplement the
                  prospectus or take other appropriate action so that the
                  Canadian and U.S. prospectuses do not include an untrue
                  statement of a material fact or omit to state a material fact

         Upon the occurrence of any event contemplated by Section 2.3(d), the
         Company shall, as soon as reasonably practicable, prepare and furnish
         to each Selling Holder and underwriter, if any, a reasonable number of
         copies of a prospectus supplemented or amended so that, as thereafter
         delivered to the purchasers of the Registrable Securities, such
         prospectus shall not contain an untrue statement of a material fact or
         omit to state a material fact required to be stated therein or
         necessary to make the statements therein, in light of the
         circumstances under which they were made, not misleading. Each Selling
         Holder of Registrable Securities agrees that upon receipt of any
         notice from the Company of the happening of any event of the kind
         described in Section 2.3(d), such Selling Holder shall forthwith
         discontinue the disposition of Registrable Securities pursuant to the
         registration statement or Canadian Prospectus applicable to such
         Registrable Securities until such Selling Holder receives copies of
         such amended or supplemented registration statement or prospectus, and
         if so directed by the Company, such Selling Holder shall deliver to
         the Company (at the Company's expense) all copies, other than
         permanent file copies, then in such Selling Holders' possession of the
         prospectus covering such Registrable Securities at the time of
         receipt of such notice.          

         The Company may require each Selling Holder as to which any
         registration statement or Canadian Prospectus is being effected to
         furnish to the Company such information regarding such holder and the
         distribution of such Registrable Securities as the Company may from
         time to time reasonably request in writing, but only to the extent that
         such information is required in order to comply with the Securities Act
         or any relevant Canadian or state securities or blue sky law or
         obligation. Each Selling Holder as to which any registration statement
         or Canadian Prospectus is being effected agrees to notify the Company
         as promptly as practicable of any inaccuracy or change in information
         previously furnished by such Selling Holder to the Company or of the
         happening of any event in either case as a result of which any
         prospectus relating to such registration contains an untrue statement
         of a material fact regarding such Selling Holder or the distribution of
         such Registrable Securities or omits to state any material fact
         regarding such Selling Holder or the distribution of such Registrable
         Securities required to be stated therein or necessary to make the
         statements therein, in light of the circumstances under which they were
         made, not misleading, and to furnish promptly to the Company any
         additional information required to correct and update any previously
         furnished information or required so that such prospectus shall not
         contain, with respect to such Selling Holder or the distribution of
         such Registrable Securities, an untrue statement of a material fact or
         omit to state a material fact required to be stated therein or
         necessary to make the statements therein, in light of the circumstances
         under which they were made, not misleading.

         In connection with each registration or filing of a Canadian prospectus
         hereunder with respect to an underwritten public offering, the Company
         and each Selling Holder shall use

         agreement with the managing underwriter or underwriters selected in
         the manner herein provided in such form and containing such provisions
         as are customary in the securities business for such an arrangement
         between underwriters and companies of the Company's size and
         investment stature, provided that such agreement shall not contain any
         such provision applicable to the Company or the Selling Holders that
         is inconsistent with the provisions hereof; and further provided, that
         the time and place of the closing under such agreement shall be as
         mutually agreed upon among the Company, the Selling Holders and such 
         managing underwriter.  

2.4      MJDS

         At any time the Company is a "foreign private issuer" within the
meaning of Rule 405 under the Securities Act and is qualified to utilize the
MJDS, the Company agrees to utilize MJDS following receipt of a Request Notice
for a demand registration as described in section 2.1(a)(i) or (iii).

2.5      Expenses

         (a)      All expenses incident to the Company's performance under or
                  compliance with this Agreement, including without limitation,
                  all registration and filing fees, blue sky fees and expenses,
                  printing expenses, listing fees, fees and disbursements of

                  transfer taxes, fees of transfer agents and registrars and

                  limitation, reasonable legal fees of one counsel for all
                  Selling Holders) of the Selling Holders, but excluding any
                  Selling Expenses (as defined below), are herein called
                  "Registration Expenses." All underwriting fees, discounts and
                  selling commissions allocable to the sale of the Registrable
                  Securities are herein called "Selling Expenses."

         (b)      Except as provided below, the Company will pay all
                  Registration Expenses in connection with each Registration
                  Statement or Canadian preliminary or final prospectus filed
                  pursuant to this Agreement, whether or not the Registration
                  Statement becomes effective, and the Selling Holders shall pay
                  Selling Expenses in connection with any Registrable Securities
                  registered pursuant to this Agreement. Notwithstanding the
                  foregoing, on the third occasion of the exercise of demand
                  registration rights pursuant to Section 2.1 hereof, each of
                  the Selling Holders (as a group) and the Company shall pay
                  one-half of all Registration Expenses except for any
                  Registration Expenses attributable to the inclusion in such

                  Company or any other Person that is not a Holder.

2.6      Indemnification

         (a)      In the event of a registration pursuant to this Agreement of
                  any Registrable Securities under the Securities Act or the
                  filing pursuant to this Agreement of a Canadian prospectus
                  offering any Registrable Securities, the Company will
                  indemnify and hold harmless each Selling Holder thereunder and
                  each underwriter of Registrable Securities thereunder and each
                  Person, if any, who controls such Selling Holder or
                  underwriter within the meaning of the Securities Act and the
                  Securities Exchange Act of 1934, as amended (the "Exchange 
                  Act"), against any losses, claims, damages or liabilities 
                  (including reasonable attorneys' fees) ("Losses"), joint or 
                  several, to which such Selling Holder or underwriter or
                  controlling Person may become subject under the Securities
                  Act, the Exchange Act, any applicable Canadian federal or
                  provincial securities legislation or otherwise, insofar as
                  such Losses, (or actions in respect thereof) arise out of or
                  are based upon any untrue statement or alleged untrue
                  statement of any material fact contained in any Registration
                  Statement under which such Registrable Securities were
                  registered under the Securities Act pursuant to this
                  Agreement, any preliminary prospectus or final prospectus
                  contained therein, or any amendment or supplement thereof, or
                  in any Canadian prospectus offering such securities, or arise
                  out of or are based upon the omission or alleged omission to
                  state therein a material fact required to be stated therein
                  or necessary to make the statements therein not misleading,
                  and will reimburse each such Selling Holder, each such
                  underwriter and each such controlling Person for any legal or
                  other expenses reasonably incurred by them in connection with
                  investigating or defending any such Loss or actions;
                  provided, however, that the Company will not be liable in any
                  such case if and to the extent that any such Loss arises out
                  of or is based upon an untrue statement or alleged untrue
                  statement or omission or alleged omission so made in
                  conformity with information furnished by such Selling Holder,
                  such underwriter or such controlling Person in writing
                  specifically for use in such Registration Statement or
                  prospectus.        

         (b)      Each Selling Holder agrees to indemnify and hold harmless the
                  Company, its directors, officers, employees and agents and
                  each Person, if any, who controls the Company within the
                  meaning of the Securities Act or of the Exchange Act to the
                  same extent as the foregoing indemnity from the Company to
                  such Selling Holder, but only with respect to information
                  regarding such Selling Holder furnished in writing by or on
                  behalf of such Selling Holder expressly for inclusion in any

                  Registration Statement or prospectus relating to the
                  Registrable Securities, or any amendment or supplement
                  thereto;

         (c)      Each Selling Holder agrees to indemnify and hold harmless each
                  other Selling Holder, their directors, officers, employees and
                  agents and each Person, if any, who controls a Selling Holder
                  within the meaning of the Securities Act or of the Exchange
                  Act to the same extent as the foregoing indemnity from the
                  Company to the Selling Holders, but only with respect to
                  information regarding such Selling Holder furnished in writing
                  by or on behalf of such Selling Holder expressly for inclusion
                  in any Registration Statement or prospectus relating to the
                  Registrable Securities, or any amendment or supplement
                  thereto; provided, however, that the liability of each Selling
                  Holder pursuant to all indemnities given by such Selling
                  Holder pursuant to this Section 2.6 shall not be greater in
                  aggregate amount than the dollar amount of the proceeds (net
                  of any Selling Expenses) received by such Selling Holder from
                  the sale of the Registrable Securities giving rise to all such
                  indemnifications.

         (d)      Promptly after receipt by an indemnified party hereunder of
                  notice of the commencement of any action, such indemnified
                  party shall, if a claim in respect thereof is to be made
                  against the indemnifying party hereunder, notify the
                  indemnifying party in writing thereof, but the omission so to
                  notify the indemnifying party shall not relieve it from any
                  liability which it may have to any indemnified party other
                  than under this Section 2.6. In case any such action shall be
                  brought against any indemnified party and it shall notify the
                  indemnifying party of the commencement thereof, the
                  indemnifying party shall be entitled to participate in and, to
                  the extent it shall wish, to assume and undertake the defense
                  thereof with counsel reasonably satisfactory to such
                  indemnified party and, after notice from the indemnifying
                  party to such indemnified party of its election so to assume
                  and undertake the defense thereof, the indemnifying party
                  shall not be liable to such indemnified party under this
                  Section 2.6 any legal expenses subsequently incurred by such
                  indemnified party in connection with the defense thereof other
                  than reasonable costs of investigation and of liaison with
                  counsel so selected; provided, however, that:

                  (i)      if the indemnifying party has failed to assume the
                           defense and employ counsel or

                  (ii)     if the defendants in any such action include both the
                           indemnified party and the indemnifying party and
                           counsel to the indemnified party shall have concluded
                           that there may be reasonable defenses available to
                           the 






<PAGE>   14

                                     - 14 -



                           indemnified party that are different from or
                           additional to those available to the indemnifying
                           party or if the interests of the indemnified party
                           reasonably may be deemed to conflict with the
                           interests of the indemnifying party, then the
                           indemnified party shall have the right to select a
                           separate counsel and to assume such legal defense and
                           otherwise to participate in the defense of such
                           action, with the reasonable expenses and fees of such
                           separate counsel and other expenses related to such
                           participation to be reimbursed by the indemnifying
                           party as incurred.

         (e)      If the indemnification provided for in this Section 2.6 is
                  unavailable to the Company or the Selling Holders or is
                  insufficient to hold them harmless in respect of any losses,
                  claims, damages, liabilities or expenses referred to herein,
                  then each such indemnifying party, in lieu of indemnifying
                  such indemnified party, shall contribute to the amount paid
                  or payable by such indemnified party as a result of such
                  losses, claims, damages, liabilities and expenses as between
                  the Company on the one hand and each Selling Holder on the
                  other, in such proportion as is appropriate to reflect the
                  relative fault of the Company on the one hand and of each
                  Selling Holder on the other in connection with the statements
                  or omissions which resulted in such losses, claims, damages
                  or liabilities, as well as any other relevant equitable
                  considerations. The relative fault of the Company on the one
                  hand and each Selling Holder on the other shall be determined
                  by reference to, among other things, whether the untrue or
                  alleged untrue statements of a material fact or the omission
                  or alleged omission to state a material fact has been made
                  by, or relates to, information supplied by such party, and
                  the parties' relative intent, knowledge, access to
                  information and opportunity to correct or prevent such
                  statement or omission.

         (f)      No Person guilty of fraudulent misrepresentation (within the
                  meaning of Section 11(f) of the Securities Act) shall be
                  entitled to contribution from any Person who is not guilty of
                  such fraudulent misrepresentation.

2.7      Covenant.

         Until no Registrable Securities remain outstanding the Company shall

                      6% CONVERTIBLE SUBORDINATED DEBENTURE
                                DUE JUNE 30, 2005

                  Repap Enterprises Inc. (hereinafter called the "Corporation")
for value received hereby acknowledges itself indebted and promises to pay to
ENRON CAPITAL & TRADE RESOURCES CORP., the registered holder hereof on June 30,
2005, or on such earlier date as the principal hereof becomes payable in
accordance with the provisions of the Indenture hereinafter mentioned, the sum
of FORTY FIVE MILLION DOLLARS in lawful money of the United States of America on
presentment and surrender of this Debenture at the principal office in Montreal
of the Trustee (as hereinafter defined) and, in the meantime, to pay interest
thereon from the date hereof or from the last interest payment date to which
interest has been paid or made available for payment on the Debentures,
whichever is later, at the rate of six per cent (6%) per annum in like money, at
the same places on July 15, 1998 and thereafter half-yearly on January 15 and
July 15 in each year (unless this Debenture shall have been previously redeemed
in accordance with the provisions of the Indenture); and should the Corporation
at any time make default in the payment of any principal or interest, to pay
interest on the amount in default at the same rate, in like money, at the same
places and half-yearly on the same dates. As interest becomes due on this
Debenture (except at maturity or on redemption when interest may, at the option
of the Corporation, be paid upon surrender of this Debenture), the Corporation,
either directly or through the Trustee, shall send by prepaid ordinary mail a
cheque for such interest (less any tax required to be withheld therefrom)
payable to the then registered holder of this Debenture and addressed to such
holder at his last address appearing on the central register or, in the case of
joint registered holders, payable to all such joint holders and addressed to all
of them at the last address appearing upon the central register of that one of
such joint holders whose name stands first on the central register as one of
such joint holders, unless otherwise directed in writing by such holder or by
all of such joint holders. Without prejudice to any other amounts due and
payable under the Indenture, the forwarding of such cheque shall satisfy and
discharge the liability for interest on this Debenture to the extent of the sum
represented thereby, plus the amount of any tax withheld as aforesaid and
remitted to the appropriate tax authorities, unless such cheque be not paid at
par on presentation at any of the places of payment above-mentioned.

                  This Debenture is one of the Debentures designated 6%
Convertible Subordinated Debentures (herein called the "Debentures") issued or
to be issued under a Trust Indenture (herein called the "Indenture") made
between the Corporation and Montreal Trust Company, as Trustee, (herein called
the "Trustee") and dated as of May 15, 1998 which Indenture and all instruments
supplemental thereto are referred to for a description of the terms and
conditions upon which the Debentures are issued and held and the rights of the
holders of the Debentures and of the Corporation and of the Trustee, all to the
same effect as if the provisions of the Indenture and all instruments
supplemental thereto were herein set forth, to all of which the holder, by
acceptance hereof, assents. The aggregate principal amount of Debentures which
may be issued under the 




<PAGE>   3

                                      -2-

Indenture is limited to USD$45,000,000 in lawful money of the United States of
America and Debentures to the said aggregate principal amount have been
authorized for immediate issue. This Debenture and all other Debentures
certified and issued under the Indenture rank pari passu. The Debentures are
direct obligations of the Corporation and are not secured by mortgage or other
charge.

                  This Debenture is convertible, in whole or in part, at the
option of the holder, at any time prior to the close of business on the earlier
of the Business Day immediately preceding June 30, 2005 or, if this Debenture
shall be called for redemption, the Business Day immediately preceding the date
fixed for its redemption, into fully paid and non-assessable Common Shares of
the Corporation (without adjustment for interest accrued hereon or for any
dividends on the Common Shares issuable upon conversion) at the price of
USD$0.35 per share, subject to and upon the terms provided in the Indenture,
which contains provisions for adjustment of the conversion privilege in the
events and in the manner therein specified.

                  The indebtedness evidenced by the Debentures is subordinate
and junior in right of payment, to the extent and in the manner provided in the
Indenture, to the prior payment of all Senior Indebtedness (as defined in the
Indenture) of the Corporation whether outstanding at the date hereof or
hereafter created, assumed, incurred or guaranteed.

                  The Debentures will not be redeemed before the third
anniversary of the issuance thereof. On and after that date and before maturity,
the Debentures are subject to redemption upon the terms set forth in the
Indenture, at the option of the Corporation, at the principal amount thereof,
plus unpaid interest accrued to the date fixed for redemption plus any
additional amounts to the extent required under the terms of the Indenture.

                  This Debenture, if for a principal amount in excess of
USD$1,000, is subject to redemption in part (being USD$1,000 or a multiple
thereof) all as more fully provided in the Indenture.

                  In case an Event of Default, as defined in the Indenture, has
occurred and is continuing the principal of all Debentures then outstanding
under the Indenture may be declared due and payable upon the conditions and in
the manner and with the effects provided in the Indenture.

                  The Indenture contains provisions for the holding of meetings
of Debentureholders and for binding all Debentureholders by resolutions passed
at such meetings by the holders of not less than a specified percentage of the
principal amount of the Debentures represented and voted or by instruments in
writing signed by the holders of not less than a specified percentage of the
principal amount of the Debentures.

                  Upon presentation at the principal office of the Trustee in
Montreal, Quebec, subject to the provisions of the Indenture and upon compliance
with the reasonable requirements

                                      -3-

of the Trustee: (a) Debentures of any denomination may be exchanged for
denominations of the same aggregate principal amount and (b) Debentures may be
transferred by the registered holder thereof or his executors, administrators
or other legal representatives or his or their attorney duly appointed in
writing but no such transfer of a Debenture shall be valid as against the
Corporation unless it has been duly noted on one of the registers maintained
for that purpose.

                  The Debentures represented hereby and the Common Shares
issuable upon conversion of such Debentures have not been registered under the
1933 Act or the securities laws of any state of the United States. As a result,
in addition to other restrictions on transfer hereunder or applicable law or
under the Indenture, the Debentures and the Common Shares may not be sold,
transferred, or delivered unless such securities are registered under the 1933
Act and the securities laws of any state in which the transferee holder is
resident or unless an exemption from such registration requirement is available
and the additional requirements for such transfer set forth in the Indenture and
this Debenture are satisfied.

                  The Common Shares issuable upon the conversion of a Debenture
(and all Common Shares issued in exchange therefor or in substitution or
transfer thereof) shall bear a legend in substantially the following form:

1.2  MEANING OF "OUTSTANDING" FOR CERTAIN PURPOSES

     Every Debenture certified and delivered by the Trustee hereunder shall be
deemed to be outstanding until it shall be cancelled or delivered to the Trustee
for cancellation or moneys for the payment thereof shall be set aside pursuant
to Article Nine, provided, however, that:

     (1)  Debentures which have been partially redeemed shall be deemed to be
          outstanding to the extent of the unredeemed part of the principal
          amount thereof;

     (2)  if a new Debenture has been issued in substitution for a Debenture
          which has been mutilated, lost, stolen or destroyed, only one of them
          shall be counted for the purpose of determining the aggregate
          principal amount of the Debentures outstanding; and

     (3)  for the purpose of any provision of this Indenture entitling holders
          of Debentures to vote, sign consents, requests or other instruments or
          take any other action under this Indenture, Debentures owned legally
          or equitably by the Corporation or any Affiliate shall be disregarded
          except that:

          (a)  for the purpose of determining whether the Trustee shall be
               protected in relying on any such vote, consent, request or other
               instrument or other action, only the Debentures which the Trustee
               knows are so owned shall be so disregarded; and

          (b)  Debentures so owned which have been pledged in good faith other
               than to the Corporation or any Affiliate shall not be so
               disregarded if the pledgee shall establish to the satisfaction of
               the Trustee the pledgee's right to vote such Debentures in his
               discretion free from the control of the Corporation or such
               Affiliate.

2.2  ISSUANCE OF DEBENTURES

     Debentures in the aggregate principal amount specified in an Order of the
Corporation referred to below may forthwith and from time to time be executed by

          certified;

     (2)  an opinion of Counsel to the effect that all legal requirements in

          certification and delivery of the Debentures.

2.3  DEBENTURES TO RANK PARI PASSU

priority.


2.4  SIGNING OF DEBENTURES

     The Debentures shall be signed by the President or the Chief Financial
Officer or any Vice President of the Corporation. The signatures of any such
officers may be mechanically reproduced in facsimile and Debentures bearing such
facsimile signatures shall be binding upon the Corporation as if they had been
manually signed by such officers. Notwithstanding that any of the individuals
whose manual or facsimile signature appears on any Debentures as one of such
officers may no longer hold office at the date of this Indenture or at the date
of such Debenture or at the date of certification and delivery thereof, any
Debenture signed as aforesaid shall be valid and binding upon the Corporation
and entitled to the benefit of this Indenture.


2.5  CERTIFICATION BY TRUSTEE

     (1)  No Debenture shall be issued or, if issued, shall be obligatory or
          entitle the holder to the benefit hereof until it has been certified
          by or on behalf of the Trustee substantially in the form of the
          certificate set out in Article 15 or in some other form approved by
          the Trustee. Such certification by the Trustee upon any Debenture
          shall be conclusive evidence as against the Corporation that the
<PAGE>   20
                                      -14-
                                                                  


          Debenture so certified has been duly issued hereunder and is a valid
          obligation of the Corporation and that the holder is entitled to the
          benefit hereof.

     (2)  The certificate of the Trustee on Debentures shall not be construed as
          a representation or warranty by the Trustee as to the validity of this
          Indenture or of the Debentures (except the due certification thereof)
          and the Trustee shall in no respect be liable or answerable for the
          use made of the Debentures or any of them or of the proceeds thereof.

2.6  TEMPORARY DEBENTURES

     (1)  Pending the preparation of definitive Debentures, the Corporation may
          execute, and upon an Order of the Corporation the Trustee shall
          deliver, temporary Debentures which are printed, lithographed,
          typewritten, mimeographed or otherwise produced, in any denomination,
          substantially of the tenor of the definitive Debentures in lieu of
          which they are issued and with such appropriate insertions, omissions,
          substitutions and other variations as the officers of the Corporation
          executing such Debentures may determine, as evidenced by their
          execution of such Debentures.

     (2)  If temporary Debentures are issued, the Corporation will cause
          definitive Debentures to be prepared without unreasonable delay. After
          the preparation of definitive Debentures, the temporary Debentures
          shall be exchangeable for definitive Debentures upon surrender of the
          temporary Debentures at the principal office of the Trustee in
          Montreal, Quebec, without charge to the holder. Upon surrender for
          cancellation of any one or more temporary Debentures, the Corporation
          shall execute and the Trustee shall certify and deliver in exchange
          therefor a like principal amount of definitive Debentures of
          authorized denominations. Until so exchanged the temporary Debentures
          shall in all respects be entitled to the same benefits under this
          Indenture as definitive Debentures.


2.7  REPLACEMENT OF DEBENTURES

     (1)  In case any Debenture shall become mutilated or be lost, destroyed or
          stolen and in the absence of notice that such Debenture has been
          acquired by a good faith purchaser the Corporation shall issue, and
          thereupon the Trustee shall certify and deliver, a new Debenture of
          like tenor as the one mutilated, lost, destroyed or stolen in exchange
          for and upon surrender and cancellation of such mutilated Debenture or
          in lieu of and in substitution for such lost, destroyed or stolen
          Debenture, and the new Debenture shall be entitled to the benefit
          hereof and rank equally in accordance with its terms with all other
          Debentures.

<PAGE>   21
                                      -15-
                                                                  



     (2)  The applicant for the issue of a new Debenture pursuant to this
          Section 2.7 shall bear the cost of the issue thereof and in case of
          loss, destruction or theft shall, as a condition precedent to the
          issue thereof, furnish to the Corporation and to the Trustee such
          evidence of ownership and of the loss, destruction or theft of the
          Debenture so lost, destroyed or stolen as shall be satisfactory to the
          Corporation in its discretion and such applicant shall also furnish
          indemnity in amount and form satisfactory to the Corporation in its
          discretion, and shall pay the reasonable charges of the Corporation
          and the Trustee or other registrar in connection therewith.

2.8  COMPUTATION OF INTEREST

     (1)  Debentures, whether issued originally or upon exchange or in
          substitution for previously issued Debentures, shall bear interest
          from their respective dates of issue or from the last interest payment
          date to which interest on the Debentures shall have been paid or made
          available for payment, whichever shall be the later.

     (2)  Interest for any period of less than six months shall be computed on
          the basis of a year of 365 days.

2.9  REPAYMENT NET OF WITHHOLDING IMPOSTS

     (1)  All payments by the Corporation under this Indenture or any Debenture,
          whether in respect of principal, interest, interest on overdue
          interest, fees or any other payment obligations, shall be made in full
          without any deduction or withholding on account of taxes or duties of
          whatsoever nature imposed or levied by or on behalf of Canada or any
          Administrative Body in Canada having power to tax unless the
          Corporation is prohibited by Law from doing so, in which event the
          Corporation shall:

          (a)  forthwith pay to the holder of each Debenture such additional
               amount so that the net amount received by the holder will equal
               the full amount which would have been received by it had no such
               deduction or withholding been made;

          (b)  pay to the relevant taxation or other authorities within the
               period for payment permitted by Law the full amount of the
               deduction or withholding (including the full amount of any
               deduction or withholding from any additional amount paid pursuant
               to this Section); and

          (c)  furnish to the holder of each Debenture promptly, as soon as
               available, an official receipt of the relevant taxation or other
               authorities involved for all amounts deducted or withheld as
               aforesaid.

<PAGE>   22
                                      -16-
                                                                  



     (2)  If as a result of any payment by the Corporation under this Indenture
          or any Debenture, whether in respect of principal, interest, interest
          on overdue interest, fees or other payment obligations, any holder of
          a Debenture is required to pay tax under Part XIII of the Income Tax
          Act (Canada) or any successor provisions in addition to and aside from
          the amounts referred to in Section 2.9(1)(b) above which have been
          paid by the Corporation, then the Corporation will, upon demand by the
          holder of any Debenture, and whether or not such taxes are correctly
          or legally asserted, indemnify the holder of each Debenture for the
          payment of any such taxes, together with any interest, penalties and
          expenses in connection therewith.

     (3)  If, following any payment made by the Corporation to any holder of
          Debentures under Section 2.9(1)(a) above or any indemnity payment made
          by the Corporation to any holder of Debentures under Section 2.9(2)
          above, such holder shall receive or be granted a refund, credit,
          allowance or remission in respect of the taxes or duties resulting in
          the payment thereof and such holder is able to readily identify such
          refund, credit, allowance or remission as being attributable to such
          taxes or duties, such holder shall, to the extent that it can do so
          without prejudice to the retention of the amount of such refund,
          credit, allowance or remission and without prejudice to the right of
          such holder to obtain any other relief or allowance which may be
          available to it, reimburse the Corporation with such amount as such
          holder, acting reasonably, determines to be the amount of money
          attributable to such refund, credit, allowance or remission that may
          be paid by such holder to leave it (after such reimbursement) in no
          worse position than it would have been in had there been no such
          deduction or withholding or payment of tax which resulted in the
          payment under Section 2.9(1)(a) or 2.9(2) above.

     (4)  Notwithstanding Sections 2.9(1)(a) and 2.9(2) above, the Corporation
          shall not be required to make any payments to a holder of a Debenture
          thereunder on account of any taxes if (i) such holder is liable for
          such taxes in respect of such Debentures by reason only of it having
          some connection with Canada other than the mere holding of such
          Debentures, or (ii) such holder would not be liable for such taxes if
          it satisfied any routine procedural statutory requirements or if it
          made a routine procedural declaration of eligibility for treaty
          benefit or other similar claim for exemption to the relevant tax
          authority (in each case which does not adversely affect its other
          affairs), but fails to do so after having been informed in writing of
          the need to do so by the Corporation (together with complete details
          setting forth all requirements and the reasons therefor) within 3
          months of such notice, all of which shall be at the expense of the
          Corporation. Furthermore, the Corporation shall not be required to
          make payments to a holder of Debentures pursuant to Section 2.9(1) or
          2.9(2) which are in excess of the amount of the payments which would
          be required to be made by it to such holder if such holder were a
          resident of the United States of America for the purposes of the
          Canada-United States Income Tax Convention.

                 REGISTRATION, TRANSFER, EXCHANGE AND OWNERSHIP

3.1  REGISTERS

     The Corporation shall cause to be kept, by and at the principal office of
the Trustee in Montreal, Quebec, a central register, in which shall be entered
all particulars required by law, including the names and latest known addresses
of the holders of Debentures and particulars of the Debentures held by them
respectively, and shall cause to be kept, by and at the principal office of the
Trustee and at such other place or places, if any, and by such other registrar
or registrars, if any, as the Corporation, with the approval of the Trustee, may
designate, a register of exchanges and transfers recording all exchanges and
transfers of Debentures. The registration of any Debenture shall be noted on
such Debenture by the Trustee or other registrar.


3.2  TRANSFERS OF DEBENTURES

     (1)  No transfer of a Debenture shall be valid unless made on a register of
          transfers herein provided for by the registered holder or such
          holder's executors, administrators or other legal representatives or
          his or their attorney duly appointed by an instrument in writing in
          form and execution satisfactory to the Trustee or other registrar upon
          compliance with such reasonable requirements as the Trustee or other
          registrar may prescribe, nor unless the name of the transferee shall
          have been noted on the Debenture by the Trustee or other registrar.

     (2)  Notwithstanding anything contained in this Indenture, in the
          Debentures or in any subscription agreements under which Debentures
          were issued and sold, neither the Trustee, relying solely on the
          transfer form or such other reasonable requirements as the Corporation
          and Trustee may prescribe pursuant to Section 3.2(1) or this Section,
          nor the Corporation shall register any transfer of a Debenture unless
          the Debenture is transferred (i) in a transaction that occurs outside
          the United States in accordance with Rule 903 or 904, as the case may
          be, of Regulation S as applicable to Category 3 securities and Rule
          905 of Regulation S and all applicable local laws and regulations;
          (ii) to a qualified institutional buyer pursuant to the exception from
          the 1933 Act provided by Rule 144A thereunder; (iii) pursuant to an
          exemption from the 1933 Act provided by Rule 144 thereunder, if
          available; (iv) pursuant to a transaction that did not require
          registration under the 1933 Act or any applicable United States laws
          and regulations governing the offer and sale of securities (in which
          case the owner of such Debenture shall provide an opinion of counsel
          satisfactory to the Corporation and the Trustee addressed to the
          Corporation and the Trustee to the effect that such resale, pledge or
          transfer is

                                      -18-
                                                                  


          exempt from registration under the 1933 Act); or (v) to the
          Corporation; however, upon receipt of such duly executed certificates,
          the Trustee will proceed with such registration, subject to such terms
          and conditions, including legending the Debentures, as may be required
          by law or by the Corporation on advice of Counsel.

     (3)  Each of the Corporation and the Trustee shall be entitled to rely, and
          the transferring holder of the Debentures shall be deemed to have
          represented and warranted to each of the Corporation and the Trustee,
          upon any transfer being made, that this transfer restriction is being
          complied with and that such transfer is in accordance with the 1933
          Act or an exemption therefrom and with applicable state securities
          laws.

3.3  EXCHANGE OF DEBENTURES

     (1)  Subject to Section 3.6, Debentures of any denomination may be
          exchanged upon reasonable notice for Debentures of the same aggregate
          principal amount in any other authorized denomination or
          denominations.

     (2)  Debentures may be exchanged at the principal office of the Trustee in
          Montreal, Quebec or at any of the places at which a register is kept
          for the Debentures pursuant to the provisions of this Article. Any
          Debenture tendered for exchange shall be surrendered to the Trustee.
          The Corporation shall execute and the Trustee shall certify all
          Debentures necessary to carry out exchanges as aforesaid. All
          Debentures surrendered for exchange shall be cancelled.

3.4  CHARGES FOR TRANSFER AND EXCHANGE

     Except as provided in Sections 2.6(2) and 4.4, for each Debenture exchanged
or transferred the Trustee may and shall, if required by the Corporation and
subject to any limitation prescribed by law, make a reasonable charge for its
services and for each new Debenture issued, if any, and payment of such charges
and reimbursement of the Trustee or the Corporation for any transfer taxes or
governmental or other charges required to be paid shall be made by the party
requesting such exchange, registration or transfer as a condition precedent
thereto.

3.5  INSPECTION OF REGISTERS AND LISTS OF HOLDERS

     (1)  The registers provided for in Section 3.1 shall at all reasonable
          times be open for inspection by the Corporation, the Trustee (if not
          the registrar) or any Debentureholder.

     (2)  Every registrar, including the Trustee, from time to time, shall:

          (a)  at the request of the Corporation or the Trustee, furnish the
               Corporation or the Trustee with a list of the names and addresses
               of the holders of Debentures entered on the register kept by such

               each such holder and the aggregate principal amount of the
               Debentures; and

          (b)  at the request of any Debentureholder, furnish such a list to
               such holder within 10 days of such request upon receiving from

               that respect.

               Debenture shall not be redeemed.


3.7  OWNERSHIP OF DEBENTURES

     (1)  Unless otherwise required by law, the Person in whose name any
          Debenture is registered shall for all purposes of this Indenture be

          the principal of such Debenture and interest thereon shall be made
          only to or upon the order in writing of such registered holder.

     (2)  Neither the Corporation nor the Trustee or other registrar shall be

          duty to a third Person, whether under a trust, express, implied or
          constructive in respect of any Debenture or otherwise, by the
          registered holder or any Person whom the Corporation or the Trustee
          treats, as permitted or required by law, as the owner or the
          registered holder of such Debenture, but shall transfer the same on
          the direction of the Person 
<PAGE>   26

          so treated or registered as the holder thereof, whether named as
          trustee or otherwise, as though that Person were the beneficial owner
          thereof.

     (3)  The registered holder for the time being of any Debenture shall be
          entitled to the principal and interest evidenced by such Debenture,
          free from all equities or rights of set-off or counterclaim between
          the Corporation and the original or any intermediate holder thereof
          save in respect of equities of which the Corporation is required to
          take notice by statute or by order of a court of competent
          jurisdiction, and all Persons may act accordingly and the receipt of
          any such holder for any such principal or interest shall be a good
          discharge to the Corporation and the Trustee for the same and neither
          the Corporation nor the Trustee shall be bound to inquire into the
          title of any such holder save as aforesaid.

opinion of counsel satisfactory to the Corporation and the Trustee addressed to
the Corporation and the Trustee to the effect that such Debenture may be freely

in each case, together with unpaid interest accrued thereon to the Redemption
Date, the applicable one of such prices together with such accrued and unpaid
interest constituting the "Redemption Price".

4.2  CONDITIONS OF REDEMPTION

     If the Corporation wishes to redeem all or part of the Debentures on a
Redemption Date that is not a date on which interest is payable on the
Debentures as provided for in Section 2.1(2), then in every such case, the
Corporation shall only be entitled to so redeem the Debentures if the Weighted
Average Price of the Common Shares for 20 consecutive days during a period of 45
days prior to the proposed Redemption Date, is equal to or exceeds the
Conversion Price.


4.3  PLACES OF PAYMENT

     The Redemption Price of Debentures called for redemption under any
provision hereof shall be payable upon presentment and surrender thereof at any
of the places where the principal of such Debentures is expressed to be payable
and at such other places, if any, as may be specified in the notice of
redemption given under Section 4.5.


4.4  PARTIAL REDEMPTION

     (1)  If less than all of the Debentures are to be redeemed at any one time,
          the Debentures to be redeemed shall be selected by lot by the Trustee
          or may be selected on a pro rata basis (to the nearest multiple of
          USD$1,000) in accordance with the principal amount of Debentures
          registered in the name of each holder or in such other manner as the
          Trustee shall deem equitable. Any part, being USD$1,000 or an integral
          multiple thereof, of a Debenture of a denomination in excess of
          USD$1,000 may be selected and called for redemption as hereinafter
          provided and all references in this Indenture to redemption of
          Debentures shall be deemed to include redemption of such parts.

     (2)  The holder of any Debenture of which part only is redeemed shall, upon
          presentment of such Debenture and receipt of the moneys payable to him
          by reason of such redemption, surrender such Debenture to the paying
          bank for transmission to the Trustee and the Trustee shall cancel the
          same and, without charge, shall forthwith certify and deliver to such
          holder a new Debenture or Debentures of aggregate principal amount
          equal to the unredeemed part of the principal amount of the Debenture
          so surrendered.

4.5  NOTICE OF REDEMPTION

     Notice of redemption of any Debentures shall be given to the Trustee and
the holders of the Debentures which are to be redeemed, not more than 60 nor
less than 30 days prior to the date fixed for redemption, in the manner provided
in Article 14. Every such notice shall specify the aggregate principal amount of
Debentures called for redemption, the date fixed for redemption, the Redemption
Price and the places of payment and shall state that interest upon the principal
amount of Debentures called for redemption shall cease to be payable from and
after the Redemption Date and that the right to convert the principal of the
Debentures so to be redeemed will terminate and expire at the Close of Business
on the Business Day immediately preceding the Redemption Date. In addition,
unless all the outstanding Debentures are to be redeemed, the notice of
redemption shall also specify:

          (a)  in the case of a notice mailed to a Debenture holder, the
               distinguishing letters and numbers of the Debentures which are to
               be redeemed (or of such thereof as are registered in the name of
               such Debentureholders);

          (b)  in the case of a published notice, the distinguishing letters and
               numbers of the Debentures which are to be redeemed; and

          (c)  in all cases, the principal amounts of such Debentures or, if any
               such Debenture is to be redeemed in part only, the principal
               amount of such part.

4.6  PAYMENT OF REDEMPTION PRICE

     Upon notice being given in accordance with Section 4.5, the principal
amount of the Debentures so called for redemption and the principal amount to be
redeemed of the Debentures so called for redemption in part shall be and become
due and payable on the Redemption Date at the Redemption Price, and with the
same effect as if it were the date of maturity specified in such Debentures,
anything therein or herein to the contrary notwithstanding and, from and after
such Redemption Date, interest upon the principal amounts so becoming due and
payable shall cease unless payment of the Redemption Price shall not be made on
presentment for surrender of such Debenture at any of the places specified in
Section 4.2, 4.3 on or after the Redemption Date and prior to the setting aside
of the Redemption Price pursuant to Article Nine.

4.7  PURCHASE OF DEBENTURES

     The Corporation shall have the right at any time and from time to time when
not in default hereunder to purchase Debentures in the market or by tender, or
by private contract at any price not exceeding the principal amount thereof at
the date of purchase, together with unpaid interest accrued thereon to the date
of purchase and costs of purchase. With respect to any purchase by the
Corporation of Debentures pursuant to this Section 4.7, unless otherwise agreed
in writing by all Debentureholders, the principal amount of Debentures so
purchased shall be allocated to all Debentures at the time outstanding in
proportion to the respective outstanding principal amounts of Debentures then
held by each Debentureholder.


4.8  CANCELLATION OF RETIRED DEBENTURES

     Subject to the provisions of Section 4.4 as to Debentures redeemed in part,
all Debentures purchased or redeemed in whole or in part under the provisions of
this Article Four shall be forthwith delivered to and cancelled by the Trustee
and no Debentures shall be issued in substitution therefor.


4.9  SPECIAL PREPAYMENT FOR ADVERSE PREPAYMENT EVENT

     If, in connection with any payment of interest on the Debentures, the
Corporation shall, as a result of the occurrence of any Prepayment Event, be
required to pay any Additional Amounts pursuant to Section 2.9 (said Section 2.9
being herein called a "TAX PAYMENT PROVISION") in excess of 10% of the aggregate
amount of such interest payment (other than as a result of the making of any
payment by the Corporation, from or through any jurisdiction other than the
United States or Canada), then the Corporation may, at its option, prepay, on a
date which is not less than 30 days and not more than 90 days after the date on
which the Corporation delivers to the holders written notice of the occurrence
of such Prepayment Event in accordance with the notice requirements of Section
14.1 (which notice shall specify that the holders have the right to waive such
prepayment pursuant to this Section 4.9), all, but not less than all, of the
Debentures with respect to which such amounts are required to be paid at 100% of
the principal amount thereof, together with all interest accrued on such
Debentures to the date fixed for prepayment, provided that (i) no prepayment
pursuant to this Section 4.9 shall in any way relieve the Corporation of any
obligation under any Tax Payment Provision with respect to payments under this
Indenture or the Debentures payable prior to or upon the making of such
prepayment and (ii) no Debentures shall be prepaid pursuant to this Section 4.9
if the holder thereof shall, not less than fifteen days prior to the date
specified for prepayment of the Debenture in the notice given by the Corporation
in accordance with the notice requirements of Section 14.1, deliver a notice to
the Corporation (which notice shall be binding on any transferee of such
Debenture), stating that such holder waives any right to payment under such Tax
Payment Provision in respect of the specific event or condition (including with
respect to the continuing or future effects of such specific event or condition
on subsequent payments) that shall have given rise to the Corporation's
prepayment

right under this Section 4.9 (it being agreed that no such waiver shall
constitute a waiver of any other right to receive a payment under such Tax
Payment Provision in respect of any event or condition other than the specific
event or condition in respect of which such waiver shall have been given) and
that the Corporation shall have all of its rights under this Section 4.9 with
respect to such other event or condition.

                                   CONVERSION

5.1  CONVERSION PRIVILEGE AND CONVERSION PRICE

     (1)  Subject to and upon compliance with the provisions of this Article
          Five, the holder of any Debenture shall have the right, at such
          holder's option, at any time prior to the Close of Business on the
          Business Day immediately preceding

          (a)  maturity, or,

          (b)  if such Debenture shall be called for redemption, the Redemption
               Date of such Debenture,

whichever is earlier, to convert such Debenture or any portion (which is an
integral multiple of USD$1,000) of the principal amount thereof into fully paid
non-assessable Common Shares at the Conversion Price.

     (2)  The Conversion Price at which Debentures shall be convertible into
          Common Shares shall be USD$0.35 per share.


5.2  CONVERSION PROCEDURE

     (1)  In order to exercise the conversion privilege, the holder of any
          Debenture to be converted shall, within the time specified in Section
          5.1, surrender such Debenture to the Trustee at its principal office
          in Montreal, Quebec, accompanied by a written notice (which shall be
          irrevocable) in the form of the "Notice of Election to Convert" set
          out in Article Fifteen, duly signed by such holder or his executors,
          administrators or other legal representative or his or their attorney
          duly appointed by an instrument in writing in form and execution
          satisfactory to the Trustee, stating:

          (a)  that such holder elects to convert such Debenture or a specified
               portion (which is an integral multiple of USD$1,000) of the
               principal amount thereof, and

<PAGE>   32
                                      -26-
                                                                  


          (b)  the names (with addresses) in which the certificates representing
               the Common Shares issuable upon such conversion are to be
               registered and, if there is more than one name, the number of
               shares to be registered in each of such names.

If any of the Common Shares into which such Debenture is to be converted are to
be issued to a Person or Persons other than the holder of such Debenture, such
notice shall be accompanied by payment to the Trustee of any transfer tax which
may be payable by reason thereof and the signature of the transferor must be
guaranteed. The surrender of such Debenture accompanied by such written notice
shall be deemed to constitute a contract between the holder of such Debenture
and the Corporation whereby:

       (i)    the holder of such Debenture subscribes for the number of Common
              Shares which such holder shall be entitled to receive on such
              conversion;


       (ii)   the holder of such Debenture releases the Corporation from all
              liability with respect to such Debenture or the portion of the
              principal amount thereof to be converted, as the case may be; and

       (iii)  the Corporation agrees that the surrender of such Debenture for
              conversion constitutes full payment of the subscription price for
              the Common Shares issuable upon such conversion.

The date of receipt by the Trustee of such Debenture and such notice is herein
referred to as the "Conversion Date" of such Debenture.

     (2)  As promptly as practicable after the Conversion Date of a Debenture,
          the Corporation shall issue or cause to be issued and deliver or cause
          to be delivered to the holder of such Debenture, or on the written
          order of such holder, a certificate or certificates in the name or
          names of the Person or Persons specified in such notice for the number
          of Common Shares deliverable upon the conversion of such Debenture (or
          specified portion thereof) and provision shall be made in respect of
          any fraction of a share as provided in Section 5.3. Such conversion
          shall be deemed to have been effected immediately prior to the Close
          of Business on the Conversion Date and, at that time, the rights of
          the holder of such Debenture as such holder shall cease and the Person
          or Persons in whose name or names any certificate or certificates for
          Common Shares shall be delivered upon such conversion shall be deemed
          to have become the holder or holders of record of the Common Shares
          represented thereby; provided, however, that the surrender of a
          Debenture for conversion on any date on which the share transfer
          registers for Common Shares shall be closed shall not be effective to
          constitute the Person or Persons entitled to receive the Common Shares
          upon such conversion as the holder or holders of record of such Common
          Shares, but such surrender shall be effective 

<PAGE>   33
                                      -27-
                                                                  
          to constitute the person or persons entitled to receive such Common
          Shares as the holder or holders of record thereof for all purposes at
          the Close of Business on the next succeeding day on which such share
          transfer registers are open. No payment or adjustment shall be made
          upon any conversion on account of any dividends declared and paid on
          the Common Shares prior to the date of conversion.

     (3)  Upon surrender to the Trustee of any Debenture which is to be
          converted in part only, the holder thereof shall be entitled to
          receive, without expense to such holder, one or more new Debentures
          for the unconverted portion of the principal amount of the Debenture
          so surrendered.


5.3  NO FRACTIONAL SHARES

     Notwithstanding anything herein contained, the Corporation shall in no case
be required to issue fractional Common Shares upon the conversion of any
Debenture. If any fractional interest in a Common Share would, except for the
provisions of this Section 5.3, be deliverable upon the conversion of any
Debenture, the Corporation shall adjust such fractional interest by payment by
cheque to the holder of such surrendered Debenture of an amount equal (to the
nearest cent) to the product of such fractional interest and the Conversion
Price in effect on the Conversion Date of such Debenture.


5.4  LEGEND ON COMMON SHARES

     The certificates representing Common Shares issuable upon the conversion of
a Debenture shall bear a legend in substantially the following form:

     "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE

          therefor or in substitution thereof will bear the same legend;
          provided, that the legend may be removed upon delivery to the Transfer
          Agent of an opinion of counsel satisfactory to the Corporation and the
          transfer agent to the effect that such Common Shares may be freely
          resold without restriction under the 1933 Act.

5.5  ADJUSTMENT OF CONVERSION PRIVILEGE

     (1)  If and whenever the Corporation shall:

          (a)  subdivide the outstanding Common Shares into a greater number of
               shares;

          (b)  consolidate the outstanding Common Shares into a smaller number
               of shares;

          (c)  issue Common Shares or securities convertible into or
               exchangeable for Common Shares as a stock dividend to all or
               substantially all the holders of Common Shares; or

          (d)  make a distribution on the outstanding Common Shares to all or
               substantially all the holders of Common Shares payable in Common
               Shares or securities convertible into or exchangeable for Common
               Shares;

any of such events being herein called a "Share Reorganization", then in each
such case the Conversion Price shall be adjusted, effective immediately after
the record date at which the holders of Common Shares are determined for the
purposes of the Share Reorganization or, if no record date is fixed, the
effective date of the Share Reorganization, by multiplying the Conversion Price
in effect on such record or effective date, as the case may be, by a fraction of
which:

               (i)  the numerator shall be the number of Common Shares
                    outstanding on such record or effective date; and

<PAGE>   35
                                      -29-
                                                                  


               (ii) the denominator shall be the number of Common Shares
                    outstanding after giving effect to such Share
                    Reorganization, including, in the case of a distribution of
                    securities convertible into or exchangeable for Common
                    Shares, the number of Common Shares that would have been
                    outstanding if such securities had been converted into or
                    exchanged for Common Shares on such record or effective
                    date.

     (2)  If and whenever the Corporation shall issue to all or substantially
          all the holders of Common Shares, rights, options or warrants under
          which such holders are entitled, during a period expiring not more
          than 45 days after the record date of such issue, to subscribe for or
          purchase Common Shares (or securities convertible into or exchangeable
          for Common Shares) at a price per share (or, in the case of securities
          convertible into or exchangeable for Common Shares, at an exchange or
          conversion price per share at the date of issue of such securities) of
          less than 95% of the Current Market Price of the Common Shares on such
          record date (any such event being herein called a "Rights Offering"),
          then in each such case the Conversion Price shall be adjusted,
          effective immediately after the record date at which holders of Common
          Shares are determined for the purposes of the Rights Offering, by
          multiplying the Conversion Price in effect on such record date by a
          fraction of which:

          (a)  the numerator shall be the sum of:

               (i)  the number of Common Shares outstanding on such record date;
                    and

               (ii) a number obtained by dividing:

                    (i)  either,

                         (I)  the product of the total number of Common Shares
                              so offered for subscription or purchase and the
                              price at which such shares are so offered, or

                         (II) the product of the maximum number of Common Shares
                              into or for which the convertible or exchangeable
                              securities so offered for subscription or purchase
                              may be converted or exchanged and the conversion
                              or exchange price of such securities,

                    as the case may be, by


<PAGE>   36
                                      -30-
                                                                  
                    (B)  the Current Market Price of the Common Shares on such
                         record date; and

          (b)  the denominator shall be the sum of:

               (i)  the number of Common Shares outstanding on such record date;
                    and

               (ii) the number of Common Shares so offered for subscription or
                    purchase (or, in the case of securities convertible into or
                    exchangeable for Common Shares, the maximum number of Common
                    Shares for or into which the securities so offered for
                    subscription or purchase may be converted or exchanged).

To the extent that such rights, options or warrants are not exercised prior to
the expiry time thereof, the Conversion Price shall be readjusted effective
immediately after such expiry time to the Conversion Price which would then have
been in effect based upon the number of Common Shares (or securities
exchangeable into Common Shares) actually delivered upon the exercise of such
rights, options or warrants.

     (3)  If and whenever the Corporation shall issue or distribute to all or
          substantially all the holders of Common Shares:

          (a)  shares of the Corporation of any class, other than Common Shares;

          (b)  rights, options or warrants;

          (c)  any other assets (excluding cash dividends and equivalent
               dividends in shares paid in lieu of Cash Dividends in the
               Ordinary Course);

and if such issuance or distribution does not constitute a Share Reorganization
or a Rights Offering (any such event being herein called a "Special
Distribution"), then in each such case the Conversion Price shall be adjusted,
effective immediately after the record date at which the holders of Common
Shares are determined for purposes of the Special Distribution, by multiplying
the Conversion Price in effect on such record date by a fraction of which:

          (i) the numerator shall be the difference between:

               (i)  the product of the number of Common Shares outstanding on
                    such record date and the Current Market Price of the Common
                    Shares on such date; and

               (ii) the fair market value, as determined by the Directors (whose
                    determination shall be conclusive), to the holders of Common
                    Shares 

<PAGE>   37
                                     -31-

               of the shares, rights, options, warrants, evidences of
               indebtedness or other assets issued or distributed in the Special
               Distribution (net of any consideration paid therefor by the
               holders of Common Shares), and

          (ii) the denominator shall be the product of the number of Common
               Shares outstanding on such record date and the Current Market
               Price of the Common Shares on such date.

     (4)  If and whenever there shall occur:

                    1.   a reclassification or redesignation of the Common
                         Shares or any change of the Common Shares into other
                         shares, otherwise than in a Share Reorganization;

                    2.   a consolidation, merger or amalgamation of the
                         Corporation with or into another body corporate; or

                    3.   the transfer of all or substantially all of the assets
                         of the Corporation to another body corporate;

(any such event being herein called a "Capital Reorganization"), then in each
such case the holder of any Debenture who exercises the Conversion Privilege
after the effective date of such Capital Reorganization shall be entitled to
receive and shall accept, upon the exercise of such right, in lieu of the number
of Common Shares to which such holder was theretofore entitled upon exercise of
the Conversion Privilege, the aggregate number of shares or other securities or
property of the Corporation or of the body corporate resulting from such Capital
Reorganization that such holder would have been entitled to receive as a result
of such Capital Reorganization if, on the effective date thereof, such holder
had been the holder of the number of Common Shares to which such holder was
theretofore entitled upon conversion; provided, however, that no such Capital
Reorganization shall be carried into effect unless all necessary steps shall
have been taken so that the holders of Debentures shall thereafter be entitled
to receive such number of shares or other securities of the Corporation or of
the body corporate resulting from such Capital Reorganization, subject to
adjustment thereafter in accordance with provisions the same, as nearly as may
be possible, as those contained in this Section 5.5 and in Section 5.6.


5.6  ADJUSTMENT RULES

     The following rules and procedures shall be applicable to adjustments of
the Conversion Privilege made pursuant to Section 5.5:

          (a)  no adjustment in the Conversion Price shall be required unless
               such adjustment would result in a change of at least 1% in the
               Conversion Price then in effect, provided, however, that any
               adjustments which, but for the 

<PAGE>   38
                                      -32-
                                                                  
               provisions of this clause 5.6(a), would otherwise have been
               required to be made, shall be carried forward and taken into
               account in any subsequent adjustment;

          (b)  no adjustment in the Conversion Price shall be made in respect of
               any event described in Section 5.5 (other than an event described
               in clauses 5.5(1)(a) or 5.5(1)(b) and in clause 5.5(4)(c)), if
               the holders of the Debentures are entitled to participate in such
               event on the same terms mutatis mutandis as if they had converted
               their Debentures prior to the effective date or record date of
               such event. The terms of any such participation shall be subject
               to the prior approval of The Toronto Stock Exchange and the
               Montreal Exchange; and

          (c)  no adjustment in the Conversion Price shall be made pursuant to
               Section 5.5 in respect of the issue from time to time of Common
               Shares to holders of Common Shares who receive substantially
               equivalent dividends in Common Shares in lieu of receiving Cash
               Dividends in the Ordinary Course.


5.7  CERTIFICATE AS TO ADJUSTMENT

     The Corporation shall from time to time immediately after the occurrence of
any event which requires an adjustment in the Conversion Privilege lodge with
the Trustee a Certificate of the Corporation specifying the nature of the event
requiring the adjustment, the amount of the adjustment necessitated thereby, the
Conversion Price after giving effect to such adjustment and setting forth, in
reasonable detail, the method of calculation and the facts upon which such
calculation is based. The Corporation shall forthwith give to the
Debentureholders notice, in the manner provided in Article Fourteen, of such
adjustment, specifying the event requiring such adjustment and the Conversion
Price after giving effect to such adjustment.


5.8  NOTICE TO DEBENTUREHOLDERS

     If the Corporation shall fix a record date for:

          (a)  any Share Reorganization (other than the subdivision of
               outstanding Common Shares into a greater number of shares or the
               consolidation of outstanding Common Shares into a smaller number
               of shares),

          (b)  any Rights Offering,

          (c)  any Special Distribution,


<PAGE>   39
                                      -33-

          (d)  any Capital Reorganization (other than a reclassification or
               redesignation of the Common Shares into other shares), or

          (e)  any cash dividend other than a Cash Dividend in the Ordinary
               Course,

the Corporation shall, not less than 14 days prior to such record date or, if no
record date is fixed, prior to the effective date of such event, give to the
Debentureholders, in the manner provided in Article Fourteen, notice of the
particulars of the proposed event to the extent that such particulars have been
determined at the time of giving the notice.


5.9  TERMINATION AND REVIVAL OF RIGHT TO CONVERT

     (1)  The right to convert any Debenture which is called for redemption
          shall terminate and expire at the Close of Business on the Business
          Day immediately preceding the Redemption Date of such Debenture,
          unless the Corporation shall make default in the payment of the
          Redemption Price of such Debenture.

     (2)  If payment of the Redemption Price of any Debenture called for
          redemption is not duly made, the right to convert such Debenture shall
          revive and continue until the earlier of payment of such Redemption
          Price and the maturity date.


5.10 CANCELLATION OF DEBENTURES

     All Debentures surrendered for conversion shall be cancelled by the Trustee
and no Debentures shall be issued in substitution therefor.


5.11 RESERVATION OF SHARES

     The Corporation shall at all times while any of the Debentures remain
outstanding reserve and keep available out of its authorized but unissued Common
Shares, for the purpose of effecting the conversion of the Debentures, such
number of Common Shares as shall from time to time be sufficient to effect the
conversion of all Debentures. As a condition precedent to the taking of any
action which would require an adjustment to the Conversion Price, the
Corporation shall take any corporate action which may, in the opinion of
Counsel, be necessary in order that the Corporation shall have unissued and
reserved in its authorized capital, and may validly and legally issue, the
shares to which the Debentureholders are entitled on the full exercise of their
conversion rights in accordance with the provisions hereof.

5.12 GOVERNMENTAL REQUIREMENTS

     If any Common Shares of the Corporation, reserved or to be reserved for the
purpose of conversion of the Debentures hereunder, require qualification with or
approval of any governmental authority under any federal, provincial or state
law before such shares may be validly issued upon conversion, the Corporation
shall take such action as may be necessary to secure such qualification or
approval, as the case may be.


                                    ARTICLE 6
                                  SUBORDINATION


6.1  AGREEMENT TO SUBORDINATE

     The indebtedness evidenced by this Indenture and the Debentures, including
the principal thereof and interest thereon (such indebtedness being hereinafter
referred to as "Subordinated Indebtedness") shall be subordinate and junior in
right of payment, in the manner set forth in this Article Six, to the prior
payment in full of the Senior Indebtedness. Each holder of a Debenture, by
acceptance thereof, agrees to and shall be bound by the provisions of this
Article Six.


6.2  DISTRIBUTION ON DISSOLUTION, WINDING-UP, LIQUIDATION OR REORGANIZATION

     (1)  Upon any Distribution of Assets of the Corporation:

          (a)  All Senior Indebtedness shall first be paid in full, or such
               payment provided for, before any payment is made on account of
               the Subordinated Indebtedness and in any such proceedings, any
               payment or Distribution of any kind or character, whether in cash
               or property or securities, which may be payable or deliverable in
               respect of the Subordinated Indebtedness shall be paid or
               delivered directly to the holders of Senior Indebtedness for
               application and payment thereof, unless and until the Senior
               Indebtedness shall have been paid and satisfied in full, or such
               payment and satisfaction shall have been provided for; provided,
               however, that:

                    1.   if payment or delivery of such cash, property or
                         securities to holders of Subordinated Indebtedness is
                         authorized by an order or decree made by a court of
                         competent jurisdiction in any proceedings under the
                         Companies Creditors Arrangement Act (Canada) or any
                         statute in replacement or substitution thereof and
                         giving effect, and stating in such order or decree that
                         effect is given, to the subordination of such
                         Subordinated Indebtedness to the Senior Indebtedness,

<PAGE>   41
                                      -35-
                                                                  
                         no payment or delivery of such cash, property or
                         securities payable or deliverable with respect to the
                         Subordinated Indebtedness need be made to the holders
                         of the Senior Indebtedness; and

                    2.   no such delivery need be made of securities which are
                         issued pursuant to voluntary reorganization,
                         dissolution or liquidation proceedings, or upon any
                         merger, consolidation, sale, lease, transfer or other
                         disposal (not prohibited by any indenture, agreement or
                         other instrument to which the Corporation or any of its
                         successors then is a party) by the Corporation or any
                         such successor, and which securities are effectively
                         made subordinate and junior in right of payment to the
                         Senior Indebtedness by provisions substantially to the
                         effect set out in this Article Six.

          (b)  The Trustee and the holders of Debentures assign to the holders
               of Senior Indebtedness, for the purposes and to the extent set
               forth in this clause 6.2(1)(b), all their right, title and
               interest in and to any payment or Distribution (other than a
               payment or Distribution referred to in subclauses (i) and (ii) of
               clause 6.2(1)(a)) of Assets of the Corporation of any kind or
               character, whether in cash, property or securities, to which they
               would be entitled in respect of the Subordinated Indebtedness
               except for the provisions of Sections 6.2 and 6.3, and agree to
               take such steps as may be necessary or appropriate to entitle the
               holders of Senior Indebtedness to receive such payment or
               Distribution, ratably according to the aggregate amount remaining
               unpaid on the Senior Indebtedness held by each, all to the extent
               necessary to provide for the payment or satisfaction of all
               Senior Indebtedness in full, after giving effect to any
               concurrent payment or Distribution, or provision therefor, to the
               holders of Senior Indebtedness, prior to any payment or
               Distribution upon the Subordinated Indebtedness; and

          (c)  If, notwithstanding the provisions of clauses 6.2(1)(a) and (b),
               any payment or Distribution (other than a payment or Distribution
               referred to in subclauses (i) and (ii) of clause 6.2(1)(a)) of
               Assets of the Corporation of any kind or character, whether in
               cash, property or securities, shall be received by the Trustee,
               by the holders of Debentures or by the Corporation in respect of
               the Subordinated Indebtedness before all Senior Indebtedness
               shall have been paid in full, such payment or Distribution shall
               be held by such party in trust (which such parties hereby declare
               and acknowledge) for the benefit of, and shall be paid over or
               delivered to, the holders of Senior Indebtedness for application
               to the payment of all Senior 


<PAGE>   42
                                      -36-

               Indebtedness remaining unpaid to the extent necessary to pay all
               such Senior Indebtedness after giving effect to any concurrent
               payment or Distribution, or provision therefor, to the holders of
               Senior Indebtedness.

     (2)  Upon any Distribution of Assets of the Corporation referred to in this
          Article Six, the Trustee and the holders of the Debentures shall be
          entitled to rely upon a Certificate of the Corporation, and/or a
          certificate of the trustee in bankruptcy, receiver, assignee for the
          benefit of creditors or other liquidating agent making such payment or
          Distribution, delivered to the Trustee or to the holders of the
          Debentures, for the purpose of ascertaining the Persons entitled to
          participate in such Distribution, the holders of Senior Indebtedness
          and other indebtedness of the Corporation, the amount thereof or
          payable thereon, the amount or amounts paid or distributed thereon and
          all other facts pertinent thereto.


6.3  SUBROGATION OF DEBENTURES

     Subject to and upon payment in full of the Senior Indebtedness, the holders
of the Debentures shall be subrogated to the rights of the holders of Senior
Indebtedness to receive payments or distributions of Assets of the Corporation
applicable to the Senior Indebtedness to the extent of the prior application
thereof of cash, property or securities of the Corporation which would have been
payable or distributable to the holders of the Debentures but for the provisions
of this Article Six, until the principal of the Debentures and interest thereon
shall be paid in full, and no such payments or distributions of Assets of the
Corporation to the holders of Senior Indebtedness which would have been payable
or distributable to the holders of the Debentures but for the provisions of this
Article Six shall, for the purposes of such subrogation, as between the
Corporation, its creditors other than the holders of Senior Indebtedness, and
the holders of the Debentures be deemed to be a payment or distribution of
Assets of the Corporation to or for the account of the holders of Senior
Indebtedness, it being understood that the provisions of this Article Six are,
and are intended, solely for the purposes of defining the relative rights of the
holders of the Debentures, on the one hand, and of the holders of Senior
Indebtedness, on the other hand.


6.4  RIGHTS OF DEBENTUREHOLDERS RESERVED

     Nothing contained herein or in the Debentures is intended to or shall
impair, as between the Corporation, its creditors other than the holders of
Senior Indebtedness, and the holders of the Debentures, the obligation of the
Corporation, which is absolute and unconditional, to pay to the holders of the
Debentures the indebtedness represented thereby, including the principal thereof
and interest thereon, as and when the same shall become due and payable in
accordance with their terms, or affect the relative rights of the holders of the
Debentures and creditors of the Corporation other than the holders of Senior
Indebtedness, nor shall anything herein or therein prevent the Trustee or the
holders of any Debenture from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the rights, if any,
under 

<PAGE>   43
                                      -37-
                                                                  
this Article Six of the holders of Senior Indebtedness in respect of Assets of
the Corporation received upon the exercise of such remedy.


6.5  AUTHORIZATION TO EFFECT SUBORDINATION

     Each holder of a Debenture, by his acceptance thereof, authorizes and
directs the Trustee on behalf of such holder to take such action as may be
necessary or appropriate to effectuate the subordination provided for in this
Article Six and appoints the Trustee attorney-in-fact of such holder for any and
all such purposes. Upon the Request of the Corporation, and upon being furnished
with a Certificate of the Corporation stating that one or more named persons are
holders of Senior Indebtedness and specifying the amount and nature of such
Senior Indebtedness, the Trustee, from time to time, for and on behalf of the
holders of the Debentures, shall execute and deliver deeds of subordination in
favour of the Person or Persons named in such Certificate of the Corporation
providing that such Person or Persons are entitled to all the rights and
benefits of this Article Six as the holder or holders of Senior Indebtedness.
Such deeds shall be conclusive evidence that the indebtedness specified therein
is Senior Indebtedness. An executed counterpart of each such deed shall be
delivered by the Trustee to the Corporation and another such counterpart shall
be retained by the Trustee. Nothing contained in this Section 6.5 shall impair
the rights of any holders of Senior Indebtedness in whose favour such a deed of
subordination has not been executed and delivered.


                                    ARTICLE 7
                          COVENANTS OF THE CORPORATION


7.1  GENERAL COVENANTS

     The Corporation covenants with the Trustee that so long as any Debentures
remain outstanding:

          (a)  It will well, duly and punctually pay or cause to be paid to
               every holder of every Debenture the principal thereof and the
               interest accrued thereon (including, in case of default, interest
               on the amount in default) at the dates and places, in the
               currency and in the manner mentioned herein and in the
               Debentures. As interest becomes due on each Debenture (except at
               maturity or on redemption when interest may, at the option of the
               Corporation, be paid upon surrender of such Debenture), the
               Corporation, either directly or through the Trustee, shall send
               no later than five Business Days prior to each date upon which
               such interest is due by prepaid ordinary mail a cheque for such
               interest (less any tax required to be withheld therefrom, if any)
               payable to the order of the registered holder of such Debenture
               and addressed to him at his last address appearing on the

<PAGE>   44
                                      -38-
                                                                  
               register, unless such holder otherwise directs. In the case of
               joint holders, the cheque shall, unless such joint holders
               otherwise direct, be made payable to the order of all of such
               joint holders and, if more than one address appears on the
               register in respect of such joint holding, the cheque shall be
               mailed to the first address so appearing, unless otherwise
               directed in writing by such holder or by all of such joint
               holders. The mailing of such cheque shall, to the extent of the
               sum represented thereby plus the amount, if any, of any tax
               withheld as aforesaid and remitted to the appropriate tax
               authorities, satisfy and discharge the liability for interest on
               such Debenture, unless such cheque be not paid at par on
               presentment at one of the places where such interest is by the
               terms of such Debenture, made payable. In the event of
               non-receipt of any cheque for interest by the person to whom it
               is so sent, the Corporation will issue to such Person a
               replacement cheque for a like amount upon being furnished with
               such evidence of non-receipt as it shall reasonably require and
               upon being indemnified to its satisfaction. Notwithstanding the
               foregoing, if the Corporation is prevented by circumstances
               beyond its control (including, without limitation, any
               interruption in mail service) from making payment of any interest
               due on each Debenture in the manner provided above, the
               Corporation may make payment of such interest or make such
               interest available for payment in any other manner acceptable to
               the Trustee with the same effect as though payment had been made
               in the manner provided above;

          (b)  Except as herein otherwise provided, it will at all times
               maintain its corporate existence; it will carry on and conduct
               its business and will cause the business of any Subsidiaries it
               may have to be carried on and conducted in a proper, efficient
               and businesslike manner and in accordance with good business
               practice; it will keep and cause any such Subsidiaries to keep
               proper books of account; and it will file with the Trustee and
               cause the Trustee to forward to the Debentureholders in a timely
               manner copies of all documents and other material of the
               Corporation furnished to its shareholders after the date hereof;
               notwithstanding the foregoing, nothing herein shall restrict the
               Corporation from amalgamating or otherwise merging with its
               Subsidiary corporation Repap New Brunswick, Inc. provided that no
               Event of Default has occurred and is then subsisting and no Event
               of Default shall occur as a result of such amalgamation or
               merger;

          (c)  It will comply in all material respects with all laws and
               regulations applicable to it and all policies and guidelines of
               any regulatory body having jurisdiction over it with respect to
               the Corporation generally, its business, the Assets of the
               Corporation and the performance of its obligations hereunder,
               including, without limitation, the payment of all taxes,
               assessments and governmental charges;


<PAGE>   45
                                      -39-
                                                                  

7.2  TRUSTEE'S REMUNERATION, EXPENSES AND INDEMNITY

     The Corporation covenants that it will pay to the Trustee from time to time
reasonable remuneration for its services hereunder and will pay or reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in the administration or execution of the trusts
created hereby (including the reasonable compensation and the disbursements of
its counsel and all other advisers and assistants not regularly in its employ),
both before any default hereunder and thereafter until all duties of the Trustee
under such trusts shall be finally and fully performed, except any such expense,
disbursement or advance as may arise from its gross negligence or bad faith.
Subject to Section 13.2(1), the Corporation shall be liable for and shall
indemnify and hold harmless the Trustee, its officers, directors, employees,
beneficiaries and shareholders from and against any and all liabilities, losses,
costs, claims, actions, expenses or demands (collectively, the "Liabilities")
which may be brought against or incurred by the Trustee, its officers,
directors, employees, beneficiaries and shareholders arising, directly or
indirectly, from any act or omission by the Trustee in the performance of its
duties and obligations hereunder except for the Liabilities which result from
the gross negligence, wilful misconduct or bad faith of the Trustee. After
default all amounts so payable and the interest thereon shall be payable out of
any funds coming into the possession of the Trustee in priority to the principal
of and interest on the Debentures. It is understood and agreed that this
indemnification shall survive the termination or discharge of this Trust
Indenture or the resignation of the Trustee.


7.3  NOT TO ACCUMULATE INTEREST

     In order to prevent any accumulation after maturity of interest, the
Corporation covenants with the Trustee that it will not, except with the
approval of the Debentureholders expressed by Extraordinary Resolution, directly
or indirectly extend or assent to the extension of time for payment of any
interest payable hereunder or be a party to or approve any such arrangement by
purchasing or funding any interest or in any other manner. In case the time for
payment of any such interest shall be so extended, whether for a definite period
or otherwise, such interest shall not be entitled in case of default hereunder
to the benefit of these presents except subject to the prior payment in full of
the principal of all Debentures and of all interest on Debentures, the payment
of which has not been so extended, and of all other moneys payable hereunder.


7.4  RESTRICTIVE COVENANT

     Subject to Section 7.13, the Corporation shall not:

          (a)  declare or pay any dividend (other than a dividend payable in
               shares of the Corporation) on any share of the Corporation; or


<PAGE>   46
                                      -40-

          (b)  redeem or purchase or make any capital distribution with respect
               to any share of the Corporation;

at any time when the Corporation is in arrears in the payment of any principal
of or interest on any of the Debentures.


7.5  REPORTING ISSUER STATUS AND STOCK EXCHANGE LISTING

     The Corporation covenants to use all reasonable efforts for so long as any
Debentures remain issued and outstanding to maintain the listing of the Common
Shares into which the Debentures are convertible on The Toronto Stock Exchange
and the Montreal Exchange and to maintain its status as a reporting issuer not
in default of any requirements of the securities legislation of the provinces of
Canada in which the Corporation is a reporting issuer at the date of this
Indenture, and the Corporation covenants and agrees to provide not less than
thirty (30) days prior written notice to the Trustee and to the registered
holders of the Debentures in the manner provided in Article Fourteen of any
decision taken by the Corporation to de-list its Common Shares from the
aforementioned exchanges or change its status as a reporting issuer not in
default under the aforementioned legislation.

forthwith deliver to each Debentureholder) within 120 days after the end of each
fiscal year of the Corporation, audited consolidated financial statements of the
Corporation for such fiscal year.

     If the Corporation shall fail to perform any of its covenants contained in
this Indenture, the Trustee may itself perform any of such covenants capable of
being performed by it, but shall be under no obligation to do so. All sums
expended or advanced by the Trustee for such purpose shall be repayable as

and all losses, costs, expenses, liabilities, actions, suits, claims or damages
of any and every kind sustained, paid or incurred by it as a result of any
environmental claims, liabilities or obligations of any and every nature
whatsoever relating to or affecting the Corporation or its Subsidiaries or the

          any clean-up, restoration, reclamation or other securing or remedial
          action in respect of their property (or any other Person's property);

          into between the Trustee, acting reasonably, and any Person with the

but shall not extend to any claim, liability or obligation to the extent that
the same relates to a decrease in the value of Debentures or the same arises
solely due to the gross negligence or wilful misconduct of the holder claiming
indemnification.

shareholders, agents and assignees of the Trustee, and the Corporation will hold
the benefit of these indemnities in trust for such indemnified parties to the

               provided further, however, that, if on the Rating Date the Credit
               Rating is an Investment Grade Rating given by both Rating
               Agencies, a Change of Control shall be deemed not to occur unless
               and until the Credit Rating shall, on or within 90 days after the
               date of the occurrence of such Change of Control (which period
               shall be extended so long as the Credit Rating is under publicly
               announced consideration for possible downgrade by either Rating
               Agency), be less than an Investment Grade Rating; or

          (j)  if the Corporation fails to maintain the listing of the Common
               Shares into which the Debentures are convertible on The Toronto
               Stock Exchange and the Montreal Exchange and to maintain its
               status as a reporting issuer not in default of any requirements
               of the securities legislation of the provinces of Canada in which
               the Corporation is a reporting issuer at the date of this
               Indenture (a "Delisting") provided that a Delisting shall be
               deemed not to occur unless and until the Credit Rating shall, on
               or within 90 days after the date of the occurrence of such
               Delisting (which period shall be extended so long as the Credit
               Rating is under publicly announced consideration for possible
               downgrade by either Rating Agency) be less than the Credit Rating
               on the date (the "Rating Date") which is 90 days before the date
               of the occurrence of such Delisting; provided further, however,
               that, if on the Rating Date, the Credit Rating is an Investment
               Grade Rating given by both Rating Agencies, a Delisting shall be
               deemed not to occur unless and until the Credit Rating shall, on
               or within 90 days after the date of the occurrence of such
               Delisting (which period shall be extended so long as the Credit
               Rating is under publicly announced consideration for possible
               downgrade by either Rating Agency) be less than an Investment
               Grade Rating.

8.2  ACCELERATION ON DEFAULT

     In case any Event of Default has occurred and is continuing, the Trustee
may in its discretion and shall, upon receipt of a Debentureholders' Request,
subject to the provisions of Section 8.4, declare the principal of and interest
on the Debentures and all other moneys payable hereunder to be due and payable
and the same shall forthwith become immediately due and payable to the Trustee
on demand, anything therein or herein to the contrary notwithstanding, and the
Corporation shall on such demand forthwith pay to the Trustee for the benefit of
the Debentureholders the principal of and unpaid interest accrued on and
interest on amounts in default under the Debentures and all other moneys payable
hereunder together with subsequent interest thereon at the rate borne by the
Debentures from the date of such declaration until payment is received by the
Trustee, such subsequent interest to be payable at the times and places and in
the moneys mentioned in and according to the tenor of the Debentures. Such
payment when made shall be deemed to have been made in discharge of the
Corporation's obligations hereunder and any moneys so received by the Trustee
shall be applied as herein provided.


8.3  NOTICE OF EVENTS OF DEFAULT

     The Corporation will promptly notify the Trustee in writing upon becoming
aware of the occurrence of any Event of Default hereunder and will in such
notice distinctly specify the Event of Default that has occurred. If an Event of
Default shall occur and be continuing the Trustee shall within 30 days after it
becomes aware of the occurrence of such Event of Default, give notice of such
Event of Default to the Debentureholders in the manner provided in Section 13.1,
provided that, notwithstanding the foregoing, the Trustee shall not be required
to give such notice if the Trustee in good faith shall have decided that the
withholding of such notice is in the best interests of the Debentureholders and
shall have so advised the Corporation in writing.


8.4  WAIVER OF DEFAULT

     In case any Event of Default has occurred otherwise than by default in
payment of any principal moneys at maturity:

          (a)  the holders of more than 50% of the principal amount of the
               Debentures shall have power (in addition to and subject to the
               powers exercisable by Extraordinary Resolution) by requisition in
               writing to instruct the Trustee to waive the default and/or to
               annul any declaration made by the Trustee pursuant to Section 8.2
               and the Trustee shall thereupon waive the default and/or annul
               such declaration upon such terms and conditions as such
               Debentureholders shall prescribe; and

          (b)  the Trustee, so long as it has not become bound to institute any
               proceedings hereunder, shall have power to waive the default if,
               in the Trustee's 
<PAGE>   53

               opinion, the same shall have been cured or adequate satisfaction
               made therefor, and in such event to annul any such declaration
               theretofore made by the Trustee in the exercise of its
               discretion, upon such terms and conditions as the Trustee may
               deem advisable;

provided, however, that no act or omission either of the Trustee or of the
Debentureholders in the premises shall extend to or be taken in any manner
whatsoever to affect any subsequent default or the rights resulting therefrom.


8.5  PROCEEDINGS BY TRUSTEE

     (1)  Whenever any Event of Default has occurred, but subject to the
          provisions of Section 8.4 and to the provisions of any Extraordinary
          Resolution:

          (a)  the Trustee, in the exercise of its discretion, may proceed to
               enforce the rights of the Trustee and the Debentureholders by any
               action, suit, remedy or proceeding authorized or permitted by law
               or by equity and may file such proofs of claim and other papers
               or documents as may be necessary or advisable in order to have
               the claims of the Trustee and of the Debentureholders lodged in
               any bankruptcy, winding-up or other judicial proceedings relative
               to the Corporation; and

          (b)  upon receipt of a Debentureholders' Request and upon receiving
               sufficient funds and being indemnified to its satisfaction as
               provided in Section 13.2, the Trustee shall exercise or take such
               one or more of the said remedies as the Debentureholders' Request
               may direct or, if such Debentureholders' Request contains no
               direction, as the Trustee may deem expedient.

     (2)  No such remedy for the enforcement of the rights of the Trustee or of
          the Debentureholders shall be exclusive of or dependent on any other
          such remedy but any one or more of such remedies may from time to time
          be exercised independently or in combination.

     (3)  Upon the exercising or taking by the Trustee of any of such remedies,
          whether or not a declaration and demand have been made pursuant to
          Section 8.2, the principal of and interest on the Debentures and all
          other moneys payable under Section 8.2 shall forthwith become due and
          payable to the Trustee as though such a declaration and a demand
          therefor had actually been made.

     (4)  All rights of action hereunder may be enforced by the Trustee without
          the possession of any of the Debentures or the production thereof on
          the trial or other proceedings relative thereto.

     (5)  No delay or omission of the Trustee or of the Debentureholders to
          exercise any remedy referred to in Section 8.5(1) shall impair any
          such remedy or shall be construed to be a waiver of any default
          hereunder or acquiescence therein.


8.6  SUITS BY DEBENTUREHOLDERS

     No holder of any Debenture shall have the right to institute any action or
proceeding or to exercise any other remedy authorized by this Indenture for the
purpose of enforcing any right on behalf of the Debentureholders or for the
execution of any trust or power hereunder or for the appointment of a liquidator
or receiver or for a receiving order under the Bankruptcy Act or to have the
Corporation wound up or to file or prove a claim in any liquidation or
bankruptcy proceedings, unless the Debentureholders' Request, funds and
indemnity referred to in Section 8.5 have been tendered to the Trustee and the
Trustee shall have failed to act within a reasonable time thereafter; in such
case, but not otherwise, any Debentureholder acting on behalf of himself and all
other Debentureholders shall be entitled to take proceedings in any court of
competent jurisdiction such as the Trustee might have taken under Section 8.5;
it being understood and intended that no one or more holders of Debentures shall
have any right in any manner whatsoever to affect, disturb or prejudice the
rights hereby created by his or their action or to enforce any right hereunder
or under any Debenture, except subject to the conditions and in the manner
herein provided, and that all powers and trusts hereunder shall be exercised and
all proceedings at law shall be instituted, had and maintained by the Trustee,
except only as herein provided, and in any event for the equal benefit of all
holders of Debentures.


8.7  APPLICATION OF MONEYS RECEIVED BY TRUSTEE

     Except as herein otherwise provided, the moneys arising from any
enforcement hereof shall be held by the Trustee and by it applied, together with
any other moneys then or thereafter in the hands of the Trustee available for
the purpose, as follows:

          (a)  firstly, in payment or reimbursement to the Trustee of the
               remuneration, expenses, disbursements and advances of the Trustee
               earned, incurred or made in the administration or execution of
               the trusts hereunder or otherwise in relation to this Indenture,
               with interest thereon as herein provided;

          (b)  secondly, but subject to Section 7.3, in payment of the principal
               of and unpaid interest accrued on the Debentures (less any tax
               required to be withheld therefrom), in that order of priority
               unless otherwise directed by Extraordinary Resolution and, in
               that case, in such order of priority as between principal and
               interest as may be directed by such Extraordinary Resolution; and

          (c)  the surplus, if any, of such moneys shall be paid to the
               Corporation or its assigns unless otherwise required by law;


<PAGE>   55
                                      -49-
                                                                  


provided, however, that no payment shall be made pursuant to the foregoing
clause (b) in respect of the principal of or interest on any Debenture held,
directly or indirectly by or for the benefit of the Corporation or any of its
Subsidiaries or Affiliates (other than any Debenture pledged for value and in
good faith to a Person other than the Corporation or any of its Subsidiaries or
Affiliates, but only to the extent of such Person's interest therein) except
subject to the prior payment in full of the principal of and interest on the
Debentures which are not so held.


8.8  DISTRIBUTION OF PROCEEDS

     Payments to holders of Debentures pursuant to clause 8.7(b) shall be made
as follows:

          (a)  at least 15 days' notice of every such payment shall be given in
               the manner provided in Article Fourteen specifying the time when
               and the place or places where the Debentures are to be presented
               and the amount of the payment and the application thereof as
               between principal and interest;

          (b)  payment of any Debenture shall be made upon presentment thereof
               at any one of the places specified in such notice and any such
               Debenture thereby paid in full shall be surrendered, otherwise a
               memorandum of such payment shall be endorsed thereon; but the
               Trustee may in its discretion dispense with presentment and
               surrender or endorsement in any special case upon such indemnity
               being given as it shall deem sufficient;

          (c)  from and after the date of payment specified in the notice,
               interest shall accrue only on the amount owing on each Debenture
               after giving credit for the amount of the payment specified in
               such notice unless such Debenture be duly presented on or after
               the date so specified and payment of such amount be not made;

          (d)  the Trustee shall not be required to make any interim payment to
               Debentureholders unless the moneys in its hands, after reserving
               therefrom such amount as the Trustee may think necessary to
               provide for the payments mentioned in clause 8.7(a), exceed 5% of
               the principal amount of the Debentures.

8.9  CURING CERTAIN EVENTS OF DEFAULT

     If an Event of Default described in Section 8.1(i) or in Section 8.1(j) has
occurred and is continuing, the Corporation may cure such Event of Default by
offering to redeem, on a date which is not less than 30 days and not more than
90 days after the date on which the Corporation delivers to the holders written
notice (a "Default Event Notice") of the occurrence of such Event of Default in
accordance with Section 14.1, the Debentures at a price equal to 101.00% of the

<PAGE>   56
                                      -50-
                                                                  


entire principal amount of the Debentures then outstanding, together with
interest accrued on such principal amount to the date fixed for prepayment.


8.10 CURRENCY CONVERSION

     Where an amount in the Indenture is denominated in U.S. dollars or Cdn.
dollars as the case may be, (the "First Currency") and for purposes of
determining compliance with the provisions of the Indenture it is necessary to
convert U.S. dollars into Cdn. dollars or vice versa (the "Other Currency"),
then the equivalent amount of the First Currency shall be that amount of the
First Currency which would be required to purchase such amount of the Other
Currency at the Bank of Canada noon (Montreal local time) rate for such
currencies on such date of determination (as quoted or published from time to
time by the Bank of Canada) or, if such date of determination is not a Business
Day, on the Business Day immediately preceding such date of determination, or of
such other rate as may be agreed upon by the Corporation and the
Debentureholders each acting reasonably.

9.1  CANCELLATION AND DESTRUCTION

     All matured Debentures shall, forthwith after payment, be cancelled and
delivered to the Trustee. All Debentures cancelled or required to be cancelled
under this or any other provision of this Indenture may, subject to applicable
law, be destroyed by or under the direction of the Trustee by cremation or
otherwise (in the presence of a representative of the Corporation, if the
Corporation shall so require) and the Trustee shall prepare and retain a
certificate of such destruction and deliver a duplicate thereof to the
Corporation.

9.2  NON-PRESENTMENT OF DEBENTURES

     In case the holder of any Debenture shall fail to present the same for
payment on the date on which the principal thereof and/or the interest thereon
becomes payable either at maturity, on redemption or otherwise, the Corporation
shall be entitled:

          (a)  to pay to the Trustee and direct it to set aside, or

          (b)  in respect of moneys in the hands of the Trustee which may or
               should be applied to the payment or redemption of the Debentures,
               to direct the Trustee to set aside,

                                      -51-
                                                                  


the principal moneys and/or the interest, as the case may be, in trust to be
paid to the holder of such Debenture upon due presentment and surrender thereof
in accordance with the provisions of this Indenture; and thereupon the principal
moneys and/or the interest payable on or represented by each Debenture in
respect whereof such moneys have been set aside shall be deemed to have been
paid and the holder thereof shall thereafter have no right in respect thereof
except that of receiving payment of the moneys so set aside by the Trustee
(without interest on such moneys) upon due presentment and surrender thereof,
subject always to the provisions of Section 9.3.


9.3  REPAYMENT OF UNCLAIMED MONEYS TO CORPORATION

     Any moneys set aside under Section 9.2 in respect of any Debenture and not
claimed by and paid to the holders of such Debenture, as provided in Section
9.2, within six years after the date of such setting aside shall be repaid to
the Corporation by the Trustee on demand, and thereupon the Trustee shall be
released from all further liability with respect to such moneys, and thereafter
such holder shall have no rights in respect of such Debenture except to obtain
payment of such moneys (without interest thereon) from the Corporation, subject
to any applicable period of prescription provided by law.


9.4  RELEASE FROM COVENANTS

     Upon proof being given to the reasonable satisfaction of the Trustee that
the principal of all Debentures and interest (including interest on amounts in
default) thereon and other moneys payable hereunder have been paid or satisfied
or that, all the Debentures having matured or having been duly called for
redemption, or the Trustee having been given irrevocable instructions by the
Corporation to publish within 90 days notice of redemption of all the
Debentures, such payment and/or redemption has been duly and effectually
provided for by payment to the Trustee or otherwise, and upon payment of all
costs, charges and expenses properly incurred by the Trustee in relation to
these presents and all interest thereon and the remuneration of the Trustee, or
upon provision satisfactory to the Trustee being made therefor, the Trustee
shall, at the request and at the expense of the Corporation, execute and deliver
to the Corporation such deeds or other instruments as shall be requisite to
release the Corporation from its covenants herein contained except those
relating to the indemnification of the Trustee.

                             SUCCESSOR CORPORATIONS


10.1 CERTAIN REQUIREMENTS IN RESPECT OF MERGER, ETC.

     The Corporation shall not enter into any transaction (whether by way of
reorganization, reconstruction, consolidation, amalgamation, merger, transfer,
sale, lease or otherwise) whereby 


<PAGE>   58
                                      -52-
                                                                  

all or substantially all of its undertaking, property and assets would become
the property of any other Person or, in the case of amalgamation, of the
continuing corporation resulting therefrom unless:

          (a)  such other Person is a body corporate (herein called a "Successor
               Corporation") incorporated under the laws of Canada or any
               province thereof;

          (b)  the Successor Corporation shall execute, prior to or
               contemporaneously with the consummation of such transaction, such
               instruments as are satisfactory to the Trustee and, in the
               opinion of Counsel, are necessary or advisable to evidence the
               assumption by the Successor Corporation of liability for the due
               and punctual payment of the Debentures and the interest thereon
               and all other moneys payable hereunder and the covenant of the
               Successor Corporation to pay the same and its agreement to
               observe and perform all the covenants and obligations of the
               Corporation under this Indenture;

          (c)  such transaction shall, to the satisfaction of the Trustee and in
               the opinion of Counsel, be upon such terms as substantially to
               preserve and not to impair any of the rights and powers of the
               Trustee or of the Debentureholders hereunder; and

          (d)  no condition or event shall exist in respect of the Successor
               Corporation at the time of such transaction and after giving full
               effect thereto which would constitute an Event of Default.

10.2 VESTING OF POWERS IN SUCCESSOR

     Whenever the conditions of Section 10.1 have been duly observed and
performed, the Successor Corporation shall succeed to and be substituted for the
Corporation with the same effect as if the Successor Corporation had been named
herein as the party of the first part, and the Successor Corporation shall
possess and from time to time may exercise each and every right and power of the
Corporation under this Indenture in the name of the Corporation or otherwise and
any act or proceeding required by any provision of this Indenture to be done or
performed by any directors or officers of the Corporation may be done and
performed with like force and effect by the like directors or officers of the
Successor Corporation.

a Request of the Corporation or a Debentureholder's Request and upon receiving
sufficient funds and being indemnified to its reasonable satisfaction by the
Corporation or by the Debentureholders signing such Debentureholders' Request,
as the case may be, against the costs which may be incurred in connection with
the calling and holding of such meeting, convene a meeting of the
Debentureholders. In the event of the Trustee failing within 30 days after
receipt of such request, funds and indemnity to give notice convening such
meeting, the Corporation or such Debentureholders, as the case may be, may
convene such meeting. Every such meeting shall be held in the city of Toronto or
at such other place as may be approved or determined by the Trustee.

been called by it and to the Corporation unless the meeting has been called by
it. Such notice shall state the time when and the place where the meeting is to
be held and shall state briefly the general nature of the business to be
transacted thereat and it shall not be necessary for any such notice to set out
the terms of any resolution to be proposed or any of the provisions of this
Article Eleven.

11.3 CHAIRMAN

     Some individual, who need not be a Debentureholder, nominated in writing by
the Trustee shall be chairman of the meeting and if no individual is so

          (b)  if a quorum of the Debentureholders shall not be present within
               30 minutes from the time fixed for holding the meeting, such
               meeting, if convened by the Debentureholders or on a
               Debentureholders' Request, shall be dissolved; but if otherwise
               convened, the meeting shall stand adjourned without notice to the
               same day in the next week (unless such day is not a Business Day
               in which case it shall stand adjourned to the next following
               Business Day thereafter) at the same time and place, unless the
               chairman shall appoint some other place, day and/or time of which
               not less than seven days' notice shall be given in the manner
               provided in Article 14; and

          (c)  at the adjourned meeting, the Debentureholders present in person

               notwithstanding that they may not represent 25% in principal
               amount of the Debentures.


11.5 POWER TO ADJOURN

     The chairman of any meeting at which a quorum of the Debentureholders is
present may, with the consent of holders of a majority in principal amount of
the Debentures represented thereat, adjourn any such meeting and no notice of
such adjournment need be given except such notice, if any, as the meeting may
prescribe.

11.6 SHOW OF HANDS

     Every question submitted to a meeting shall be decided in the first place
by a majority of the votes given on a show of hands except that votes on
Extraordinary Resolutions shall be given in the manner hereinafter provided. At
any such meeting, unless a poll is duly demanded as herein provided, a
declaration by the chairman that a resolution has been carried or carried
unanimously or by a particular majority or lost or not carried by a particular
majority shall be conclusive evidence of the fact.


11.7 POLL

     On every Extraordinary Resolution, and on any other question submitted to a
meeting when demanded after a vote by show of hands by the Chairman or by any
Debentureholders acting in person or by proxy, a poll shall be taken in such

11.8 VOTING

     On a show of hands, every person who is present and entitled to vote,

or both, shall have one vote. On a poll, each Debentureholder present in person
or represented by a proxy duly appointed by instrument in writing shall be
entitled to one vote in respect of each USD$1,000 principal amount of Debentures
of which he shall then be the holder. A proxy need not be a Debentureholder.
Joint registered holders of a Debenture shall vote together in respect of
Debentures of which they are joint registered holders and may be represented in
person or by proxy by any one of them.


11.9 REGULATIONS

     The Trustee, or the Corporation with the approval of the Trustee, may from
time to time make and from time to time vary such regulations as it shall from
time to time think fit:

          (a)  for the deposit of instruments appointing proxies at such place
               as the Trustee, the Corporation or the Debentureholders convening
               the meeting, as the case may be, may in the notice convening the
               meeting direct; and

          (b)  for the deposit of instruments appointing proxies at some
               approved place or places other than the place at which the
               meeting is to be held and enabling particulars of such
               instruments appointing proxies to be mailed, cabled or sent by
               any other means of recorded communication before the meeting to
               the Corporation or to the Trustee at the place where the same is
               to be held and for the voting of proxies so deposited as though
               the instruments themselves were produced at the meeting.

Any regulations so made shall be binding and effective and the votes given in
accordance therewith shall be valid and shall be counted. Save as such
regulations may provide, the only persons who shall be recognized at any meeting
as the holders of any Debentures, or as entitled to vote or be present at the
meeting in respect thereof, shall be the registered holders of Debentures and
persons whom registered holders of Debentures have by instrument in writing duly
appointed as their proxies.

<PAGE>   63
                                      -57-

          (g)  power to assent to any modification of or change in or omission
               from the provisions contained herein which shall be agreed to by

               execute any deed or instrument supplemental hereto embodying such
               modification, change or omission;

          (h)  power to repeal, modify or amend any Extraordinary Resolution

               such appointment may provide for payment of the expenses and
               disbursements of and compensation to such committee. Such
               committee shall consist of such number of persons as shall be
               prescribed in the Extraordinary Resolution appointing it, and the
               members need not themselves be Debentureholders. Subject to the
               Extraordinary resolution appointing it, every such committee may
               elect its chairman and may make regulations respecting its
               quorum, the calling of its meetings, the filling of vacancies
               occurring in its number, the manner in which it may act and its
               procedure generally and such regulations may provide that the
               committee may act at a meeting at which a quorum is present or
               may act by resolutions signed by a majority of the members
               thereof or the number of members thereof necessary to constitute
               a quorum, whichever is the greater. All acts of any such
               committee within the authority delegated to it shall be binding
               upon all Debentureholders.

11.12 MEANING OF "EXTRAORDINARY RESOLUTION"

      (1)  The expression "Extraordinary Resolution" means, subject as
           hereinafter in this Section 11.12 and in Section 11.15 provided, a
           resolution at a meeting of Debentureholders duly convened for the
           purpose and held in accordance with the provisions of this Article
           Eleven at which the holders of more than 50% in principal amount of
           the Debentures are present in person or by proxy and passed by the
           favourable votes of the holders of not less than 66 2/3% of the
           principal amount of Debentures represented at the meeting and voted
           on a poll upon such resolution.


<PAGE>   64
                                      -58-
                                                                  

      (2)  If at any such meeting the holders of more than 50% in principal
           amount of the Debentures are not present in person or by proxy within
           30 minutes after the time appointed for the meeting, then the
           meeting, if convened by Debentureholders or on a Debentureholders'
           Request, shall be dissolved; but if otherwise convened, the meeting
           shall stand adjourned to such date, being not less than 14 nor more
           than 60 days later, and to such place and time as may be appointed by
           the chairman. Not less than seven days notice shall be given of the
           time and place of such adjourned meeting in the manner provided in
           Article 14. Such notice shall state that at the adjourned meeting the
           Debentureholders present in person or by proxy shall constitute a
           quorum but it shall not be necessary to set forth the purposes for
           which the meeting was originally called or any such particulars. At
           the adjourned meeting the Debentureholders present in person or by
           proxy shall constitute a quorum and may transact the business for
           which the meeting was originally convened and a resolution proposed
           at such adjourned meeting and passed by the requisite vote as
           provided in Section 11.12(1) shall be an Extraordinary Resolution
           within the meaning of this Indenture, notwithstanding that the
           holders of more than 50% in principal amount of the Debentures are
           not present in person or by proxy at such adjourned meeting.

      (3)  Votes on an Extraordinary Resolution shall always be taken by a poll
           and no demand for a poll on an Extraordinary Resolution shall be
           necessary.


11.13 POWERS CUMULATIVE

      It is hereby declared and agreed that any one or more of the powers and/or
combination of the powers in this Indenture stated to be exercisable by the
Debentureholders by Extraordinary Resolution or otherwise may be exercised from
time to time and the exercise of any one or more of such powers or any
combination of powers from time to time shall not be deemed to exhaust the right
of the Debentureholders to exercise such powers or powers or combination of
powers thereafter from time to time.

11.14 MINUTES

      Minutes of all resolutions and proceedings at every meeting of the
Debentureholders shall be made and duly entered in books to be from time to time
provided for that purpose by the Trustee at the expense of the Corporation, and
any such minutes, if signed by the chairman of the meeting at which such
resolutions were passed or proceedings had, or by the chairman of the next
succeeding meeting of the Debentureholders, shall be prima facie evidence of the
matters therein stated and, until the contrary is proved, every such meeting in
respect of the proceedings of which minutes shall have been made, shall be
deemed to have been duly held and convened, and all resolutions passed thereat
or proceedings had, to have been duly passed and had.

amount of all the Debentures by an instrument in writing signed in one or more
counterparts and the expression 'Extraordinary Resolution' when used in this
Indenture shall include an instrument so signed.


11.16 BINDING EFFECT OF RESOLUTIONS

      Every resolution and every Extraordinary Resolution passed in accordance
with the provisions of this Article Eleven at a meeting of Debentureholders
shall be binding upon all the Debentureholders, whether present at or absent
from such meeting, and every instrument in writing signed by Debentureholders in
accordance with Section 11.15 shall be binding upon the Debentureholders,
whether signatories thereto or not, and each and every Debentureholder and the
Trustee (subject to the provisions for its indemnity herein contained) shall be
bound to give effect accordingly to every such resolution, Extraordinary
Resolution and instrument in writing.

               herein provided for and for the exchange of Debentures of
               different forms and denominations or making

               any modification in the forms of the Debentures which does not

          (d)  making any additions to, deletions from or alterations of the
               provisions of this Indenture or the Debentures which, in the

               Debentureholders are not prejudiced thereby; and

          (f)  any other purposes not inconsistent with the provisions of this
               Indenture, provided that, in the opinion of the Trustee, the
               rights of the Trustee and of the Debentureholders are not
               prejudiced thereby.


                                   ARTICLE 13
                             CONCERNING THE TRUSTEE

13.1 TRUST INDENTURE LEGISLATION

     (1)  In this Article 13, the term "Indenture Legislation" means the
          provisions, if any, of the Canada Business Corporations Act and, to
          the extent that such provisions are at the time in force and
          applicable to this Indenture, any other statute of Canada or a
          province thereof, and the respective regulations thereunder relating
          to trust indentures and/or to the rights, duties and obligations of
          trustees under trust indentures and of corporations issuing debt
          obligations under trust indentures.

     (2)  If and to the extent that any provision of this Indenture limits,
          qualifies or conflicts with a mandatory requirement of Indenture
          Legislation, such mandatory requirement shall prevail.

     (3)  The Corporation and the Trustee agree that each will at all times in
          relation to this Indenture and any action to be taken hereunder
          observe and comply with and be entitled to the benefits of Indenture
          Legislation, including the requirement that the Corporation deliver a
          statutory declaration or certificate pursuant to Section 87 of the
          Canadian Business Corporations Act.


13.2 RIGHTS AND DUTIES OF TRUSTEE

     (1)  In exercising the powers and discharging the duties conferred by the
          terms of this Indenture, the Trustee shall act honestly and in good
          faith with a view to the best 


<PAGE>   67
                                      -61-
                                                                  
          interests of the Debentureholders and exercise the care, diligence and
          skill of a reasonably prudent trustee.

     (2)  The Trustee shall not be required to take notice or be deemed to have
          notice or actual knowledge of any matter hereunder, including an Event
          of Default, unless the Trustee shall have received from the
          Corporation or a Debentureholder written notice distinctly stating the
          matter in respect of which the Trustee should have notice or actual
          knowledge and in the absence of such notice, the Trustee may for all
          purposes of this Trust Indenture, conclusively assume that the
          Corporation is not in default hereunder and that no Event of Default
          has occurred.

     (3)  The obligation of the Trustee to commence or continue any act, action
          or proceeding for the purpose of enforcing any rights of the Trustee
          or the Debentureholders hereunder shall be conditional upon the
          Debentureholders furnishing, when required by notice in writing by the
          Trustee, sufficient funds to commence or continue such act, action or
          proceeding and indemnity reasonably satisfactory to the Trustee to
          protect and hold harmless the Trustee against the expenses and
          liabilities to be incurred thereby and any loss and damage it may
          suffer by reason thereof except such as may arise from its negligence
          or bad faith. None of the provisions contained in this Indenture shall
          require the Trustee to expend or risk its own funds or otherwise incur
          financial liability in the performance of any of its duties or in the
          exercise of any of its rights or powers unless indemnified as
          aforesaid.

     (4)  The Trustee may, before commencing or at any time during the
          continuance of any act, action or proceeding referred to in Section
          13.2(3), require the Debentureholders at whose instance it is acting
          to deposit with the Trustee the Debentures held by them, for which
          Debentures the Trustee shall issue receipts.

     (5)  Every provision of this Indenture that by its terms relieves the
          Trustee of liability or entitles it to rely upon any evidence
          submitted to it, is subject to the provisions of Indenture
          Legislation, of this Section 13.2 and of Section 13.3.

13.3 EVIDENCE, EXPERTS AND ADVISERS

     (1)  In addition to the reports, certificates, opinions and other evidence
          required by this Indenture, the Corporation shall furnish to the
          Trustee such additional evidence of compliance with any provision
          hereof, and in such form, as may be prescribed by Indenture
          Legislation or as the Trustee may reasonably require by written notice
          to the Corporation.

     (2)  In the exercise of its rights and duties, the Trustee may, if it is
          acting in good faith, rely as to the truth of the statements and the

          therein, upon statutory declarations, opinions, reports, certificates
          or other evidence furnished to the Trustee pursuant to any provision
          hereof or of Indenture Legislation or pursuant to a request of the
          Trustee, provided that such evidence complies with Indenture
          Legislation and that the Trustee examines the same and determines that
          such evidence complies with the applicable requirements of this
          Indenture.

     (3)  Whenever Indenture Legislation requires that evidence referred to in
          Section 13.3(1) be in the form of a statutory declaration, the Trustee
          may accept such statutory declaration in lieu of a Certificate of the
          Corporation required by any provision hereof. Any such statutory
          declaration may be made by one or more of the president,
          vice-presidents, secretary, controller or treasurer of the
          Corporation.

     (4)  Proof of the execution of an instrument in writing, including a
          Debentureholders' Request, by any Debentureholder may be made by the
          certificate of a notary public, or other officer with similar powers,
          that the person signing such instrument acknowledged to such notary
          the execution thereof, or by an affidavit of a witness to such
          execution or in any other manner which the Trustee may consider
          adequate.

     (5)  The Trustee may employ or retain such counsel, accountants, engineers,
          appraisers or other experts or advisers as it may reasonably require
          for the purpose of discharging its duties hereunder and may pay
          reasonable remuneration for all services so performed by any of them
          for which it shall be reimbursed by the Corporation under Section 7.2,
          without taxation of costs of any counsel, and shall not be responsible
          for any misconduct on the part of any of them. The Trustee may act and
          shall be protected in acting in good faith on the opinion or advice of
          or information obtained from any counsel, accountant, appraiser or
          other expert or adviser, whether retained or employed by the
          Corporation or by the Trustee, in relation to any matter arising in
          the administration of the trusts hereof.

     (6)  Any opinion of Counsel may be based, insofar as it relates to factual
          matters, upon information with respect to such matters which is in the
          possession of the Corporation, upon the certificate or opinion or
          representation or any officer of the Corporation unless such Counsel
          knows that the certificate or opinion or representation with respect
          to the matters upon which Counsel's opinion may be based are erroneous
          or, in the exercise of reasonable care, should have known that the
          same were erroneous.

          any time be held by the Trustee subject to the trusts hereof may be

          Trustee or of any Canadian chartered bank (including an Affiliate of
          the Trustee) or deposited for safekeeping with any such bank.

     (2)  Unless herein otherwise expressly provided, any moneys held by the
          Trustee hereunder, pending the application or withdrawal thereof under
          any provision of this Indenture, may and shall at the written
          direction of the Corporation be deposited in the name of the Trustee,
          at the rate of interest (if any) then current on similar deposits, in
          any Canadian chartered bank or trust company (including the Trustee or
          an Affiliate of the Trustee) having a shareholders' equity according
          to its most recently published audited annual statement of assets and
          liabilities of at least CDN$250,000,000 (a "Qualified Institution")
          or, upon the written direction of the Corporation, may be (i)
          deposited in the deposit department of the Trustee or any other loan
          or trust company authorized to accept deposits under the laws of

          or guaranteed by the Government of Canada or any province thereof or
          in obligations, maturing not more than one year from the date of
          investment of any Qualified Institution. The Trustee shall not be
          subject to any liability whatsoever in respect of any loss or
          diminution in value incurred as a result of complying with the
          Corporation's written direction to invest in securities pursuant to
          this Section 13.4(2)(ii).

     (3)  Unless an Event of Default shall have occurred and be continuing, all
          interests or other income received by the Trustee in respect of
          deposits and investments made pursuant to this Section 13.4 shall
          belong to the Corporation.

     (4)  The Trustee, for the purpose of immediately applying the proceeds of
          any investment made pursuant to this Section 13.4 to the redemption or
          purchase of Debentures, may and shall at the written direction of the
          Corporation sell the same at the best prices obtainable in the opinion
          of the Trustee. The Corporation shall reimburse the Trustee for any
          loss realized on any such sale. Unless an Event of Default shall have
          occurred and be continuing, any profit realized by the Trustee upon
          any such sale shall belong to the Corporation.

13.5 ACTION BY TRUSTEE TO PROTECT INTERESTS

proceedings as it may consider necessary or expedient to preserve, protect or
enforce its interest and the interests of the holders of Debentures.

13.7 PROTECTION OF TRUSTEE

     By way of supplement to the provisions of any law for the time being
relating to trustees, it is expressly declared and agreed as follows:

          (a)  the Trustee shall not be liable for or by reason of any
               statements of fact or recitals in this Indenture or in the
               Debentures (except the representation contained in Section 13.9
               or in the certificate of the Trustee on the Debentures) or
               required to verify the same, but all such statements or recitals
               are and shall be deemed to be made by the Corporation.

          (b)  nothing herein contained shall impose any obligation on the
               Trustee to see to or to require evidence of the registration or
               filing (or renewal thereof) of this Indenture or any instrument
               ancillary or supplemental hereto;

          (c)  the Trustee shall not be bound to give notice to any Person of
               the execution hereof;

          (d)  the Trustee shall not incur any liability or responsibility
               whatever or be in any way responsible for the consequence of any
               breach on the part of the Corporation of any of the covenants
               herein contained or of any acts of the agents or servants of the
               Corporation; and

          (e)  the Trustee, in its personal capacity or any other capacity, and
               any Affiliate of the Trustee, may buy, sell, lend upon, become a
               pledgee of and deal in the Debentures and generally contract and
               enter into financial transactions with the Corporation without
               being liable to account for any profits made thereby.

13.8 REPLACEMENT OF TRUSTEE

     The Trustee may resign its trust and be discharged from all further duties
and liabilities hereunder by giving to the Corporation not less than 60 days'
notice in writing or such shorter notice as the Corporation may accept as
sufficient. The Debentureholders by Extraordinary Resolution shall have power at
any time to remove the Trustee and to appoint a new Trustee. In the event of the
Trustee resigning or being removed as aforesaid or being dissolved, becoming
bankrupt, going into liquidation or otherwise becoming incapable of acting
hereunder, the Corporation shall forthwith appoint a new Trustee unless a new
Trustee has already been appointed by the Debentureholders; failing such
appointment by the Corporation, the retiring Trustee or any Debentureholder may
apply to the Court of Queen's Bench of Ontario, on such notice as such Court may
direct, for the appointment of a new Trustee; but any new Trustee so appointed
by the Corporation or by the Court shall be subject to removal as aforesaid by
the 


<PAGE>   71
                                      -65-
                                                                  

Debentureholders. Any new Trustee appointed under any provision of this Section
13.8 shall be a corporation authorized to carry on the business of a trust
corporation in the Province of Ontario and, if required by the Indenture
Legislation of any other province, in such other province. On any such
appointment, the new Trustee shall be vested with the same powers, rights,
duties and responsibilities as if it had been originally named herein as Trustee
without any further assurance, conveyance, act or deed, but there shall be
immediately executed, at the expense of the Corporation, all such conveyances or
other instruments as, in the opinion of Counsel, may be necessary or advisable
for the purpose of assuring the same to the new Trustee. At the request of the
Corporation or the new Trustee, the retiring Trustee, upon payment of the
amounts, if any, due to it pursuant to Section 7.2, shall duly assign, transfer
and deliver to the new Trustee all property and money held and all records kept
by the retiring Trustee hereunder or in connection herewith.


13.9 CONFLICT OF INTEREST

     (1)  The Trustee represents to the Corporation that at the time of the
          execution and delivery hereof no material conflict of interest exists
          in the Trustee's role as a fiduciary hereunder and any other role of
          the Trustee and agrees that in the event of a material conflict of
          interest arising hereafter it will, within 60 days after ascertaining
          that it has such material conflict of interest, either eliminate the
          same or resign its trust hereunder.

     (2)  Subject to Section 13.1, the Trustee, in its personal or any other
          capacity, may buy, lend upon and deal in securities of the Corporation
          and generally may contract and enter into financing transactions with
          the Corporation or any Subsidiary it may have from time to time
          without being liable to account for any profit made thereby.

conditions herein set forth.

holders at their respective addresses appearing on the central register
mentioned in Article Three; and, if in the case of joint holders of any
Debenture more than one address appear in the central register in respect of
such joint holding, such notice shall be addressed only to the first address so
appearing, provided, however, that if any notice so given would be unlikely to
reach the Debentureholders to whom it is addressed in the ordinary course of
post by reason of an interruption in mail service, whether at the place of
dispatch or receipt or both, the Corporation shall give such notice by
publication once (twice in the case of a notice of a meeting of
Debentureholders) in the City of Toronto and New York City; each such
publication to be made in a daily newspaper of general national circulation in
the English language and approved by the Trustee. Any notice so given by mail
shall be deemed to have been given on the day of mailing. Any notice so given by
publication shall be deemed to have been given on the day on which publication
shall have been effected at least once in the newspaper in which publication was
required. In determining under any provision hereof the date when notice of any
meeting, redemption or other event must be given, the date of giving the notice
shall be included and the date of the meeting, redemption or other event shall
be excluded. Accidental error or omission in giving notice or accidental failure
to mail notice to any one or more Debentureholders shall not invalidate any
action or proceeding founded thereon.

14.4 MAIL SERVICE INTERRUPTION

     If by reason of any interruption of mail service, actual or threatened, any
notice to be given to the Trustee or to the Corporation would reasonably be
unlikely to reach its destination by the time notice by mail would have been
deemed to have been given pursuant to Section 14.2 or 14.3, such notice shall be
valid and effective only if delivered on a Business Day to an officer of the
party to which it is addressed or if sent to such party, at the appropriate
address in accordance with Section 14.2 or 14.3, as the case may be, by fax.

                     (INCORPORATED UNDER THE LAWS OF CANADA)

                      6% CONVERTIBLE SUBORDINATED DEBENTURE
                                DUE JUNE 30, 2005

          Repap Enterprises Inc. (hereinafter called the "Corporation") for
value received hereby acknowledges itself indebted and promises to pay to the
registered holder hereof on June 30, 2005, or on such earlier date as the
principal hereof becomes payable in accordance with the provisions of the
Indenture hereinafter mentioned, the sum of __ DOLLARS in lawful money of the
United States of America on presentment and surrender of this Debenture at the
principal office in Montreal of the Trustee (as hereinafter defined) and, in the
meantime, to pay interest thereon from the date hereof or from the last interest
payment date to which interest has been paid or made available for payment on
the Debentures, whichever is later, at the rate of six per cent (6%) per annum
in like money, at the same places on July 15, 1998 and thereafter half-yearly on
January 15 and July 15 in each year (unless this Debenture shall have been
previously redeemed in accordance with the provisions of the Indenture); and
should the Corporation at any time make default in the payment of any principal
or interest, to pay interest on the amount in default at the same rate, in like
money, at the same places and half-yearly on the same dates. As interest becomes
due on this Debenture (except at maturity or on redemption when interest may, at
the option of the Corporation, be paid upon surrender of this Debenture), the
Corporation, either directly or through the Trustee, shall send by prepaid
ordinary mail a cheque for such interest (less any tax required to be withheld
therefrom) payable to the then registered holder of this Debenture and addressed
to such holder at his last address appearing on the central register or, in the
case of joint registered holders, payable to all such joint holders and
addressed to all of them at the last address appearing upon the central register
of that one of such joint holders whose name stands first on the central
register as one of such joint holders, unless otherwise directed in writing by
such holder or by all of such joint holders. Without prejudice to any other
amounts due and payable under the Indenture, the forwarding of such cheque shall
satisfy and discharge the liability for interest on this Debenture to the extent
of the sum represented thereby, plus the amount of any 
<PAGE>   75
                                      -69-
                                                                  

tax withheld as aforesaid and remitted to the appropriate tax authorities,
unless such cheque be not paid at par on presentation at any of the places of
payment above-mentioned.

          This Debenture is one of the Debentures designated 6% Convertible
Subordinated Debentures (herein called the "Debentures") issued or to be issued
under a Trust Indenture (herein called the "Indenture") made between the
Corporation and Montreal Trust Company, as Trustee, (herein called the
"Trustee") and dated as of May 15, 1998 which Indenture and all instruments
supplemental thereto are referred to for a description of the terms and
conditions upon which the Debentures are issued and held and the rights of the
holders of the Debentures and of the Corporation and of the Trustee, all to the
same effect as if the provisions of the Indenture and all instruments
supplemental thereto were herein set forth, to all of which the holder, by
acceptance hereof, assents. The aggregate principal amount of Debentures which
may be issued under the Indenture is limited to USD$45,000,000 in lawful money
of the United States of America and Debentures to the said aggregate principal
amount have been authorized for immediate issue. This Debenture and all other
Debentures certified and issued under the Indenture rank pari passu. The
Debentures are direct obligations of the Corporation and are not secured by
mortgage or other charge.

          This Debenture is convertible, in whole or in part, at the option of
the holder, at any time prior to the close of business on the earlier of the
Business Day immediately preceding June 30, 2005 or, if this Debenture shall be
called for redemption, the Business Day immediately preceding the date fixed for
its redemption, into fully paid and non-assessable Common Shares of the
Corporation (without adjustment for interest accrued hereon or for any dividends
on the Common Shares issuable upon conversion) at the price of USD$0.35 per
share, subject to and upon the terms provided in the Indenture, which contains
provisions for adjustment of the conversion privilege in the events and in the
manner therein specified.

          The indebtedness evidenced by the Debentures is subordinate and junior
in right of payment, to the extent and in the manner provided in the Indenture,
to the prior payment of all Senior Indebtedness (as defined in the Indenture) of
the Corporation whether outstanding at the date hereof or hereafter created,
assumed, incurred or guaranteed.

          The Debentures will not be redeemed before the third anniversary of
the issuance thereof. On and after that date and before maturity, the Debentures
are subject to redemption upon the terms set forth in the Indenture, at the
option of the Corporation, at the principal amount thereof, plus unpaid interest
accrued to the date fixed for redemption plus any additional amounts to the
extent required under the terms of the Indenture.

          This Debenture, if for a principal amount in excess of USD$1,000, is
subject to redemption in part (being USD$1,000 or a multiple thereof) all as
more fully provided in the Indenture.

          In case an Event of Default, as defined in the Indenture, has occurred
and is continuing the principal of all Debentures then outstanding under the
Indenture may be declared

                                      -70-
                                                                  


due and payable upon the conditions and in the manner and with the effects
provided in the Indenture.

          The Indenture contains provisions for the holding of meetings of
Debentureholders and for binding all Debentureholders by resolutions passed at
such meetings by the holders of not less than a specified percentage of the
principal amount of the Debentures represented and voted or by instruments in
writing signed by the holders of not less than a specified percentage of the
principal amount of the Debentures.

          Upon presentation at the principal office of the Trustee in Montreal,
Quebec, subject to the provisions of the Indenture and upon compliance with the
reasonable requirements of the Trustee: (a) Debentures of any denomination may
be exchanged for denominations of the same aggregate principal amount and (b)
Debentures may be transferred by the registered holder thereof or his executors,
administrators or other legal representatives or his or their attorney duly
appointed in writing but no such transfer of a Debenture shall be valid as
against the Corporation unless it has been duly noted on one of the registers
maintained for that purpose.

          The Debentures represented hereby and the Common Shares issuable upon
conversion of such Debentures have not been registered under the 1933 Act or the
securities laws of any state of the United States. As a result, in addition to
other restrictions on transfer hereunder or applicable law or under the
Indenture, the Debentures and the Common Shares may not be sold, transferred, or
delivered unless such securities are registered under the 1933 Act and the
securities laws of any state in which the transferee holder is resident or
unless an exemption from such registration requirement is available and the
additional requirements for such transfer set forth in the Indenture and this
Debenture are satisfied.

          The Common Shares issuable upon the conversion of a Debenture (and all
Common Shares issued in exchange therefor or in substitution or transfer
thereof) shall bear a legend in substantially the following form:

     "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
     UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "1933 ACT"). THE

     REGISTRATION STATEMENT UNDER THE 1933 ACT. THE HOLDER HEREOF FURTHER AGREES
     THAT HEDGING TRANSACTIONS INVOLVING SUCH SECURITIES MAY NOT BE CONDUCTED
     UNLESS IN COMPLIANCE WITH THE 1933 ACT. DELIVERY OF THIS CERTIFICATE MAY
     NOT CONSTITUTE "GOOD DELIVERY" IN SETTLEMENT OF TRANSACTIONS ON STOCK

     WHICH WILL CONSTITUTE "GOOD DELIVERY" MAY BE OBTAINED FROM MONTREAL TRUST
     COMPANY, AS REGISTRAR AND TRANSFER AGENT FOR THE CORPORATION, UPON DELIVERY
     OF THIS CERTIFICATE AND AN OPINION OF COUNSEL SATISFACTORY TO THE
     CORPORATION AND THE TRANSFER AGENT ADDRESSED TO THE CORPORATION AND THE
     TRANSFER AGENT TO THE EFFECT THAT SUCH SECURITIES MAY BE FREELY RESOLD
     WITHOUT RESTRICTION UNDER THE 1933 ACT."

and all certificates representing Common Shares issued in exchange therefor or
in substitution thereof will bear the same legend; provided, that the legend may
be removed upon delivery to the transfer agent of an opinion of counsel
satisfactory to the Corporation and the transfer agent to the effect that such
Common Shares may be freely resold without restriction under the 1933 Act.

          This Debenture shall not become obligatory for any purpose until it
shall have been certified by or on behalf of the Trustee for the time being
under the Indenture.
