         appoint a successor Security Agent who (at any time that no Event of
         Default has occurred and is continuing) shall be acceptable to the
         Grantor, acting reasonably. If no successor Security Agent is appointed
         or has accepted the appointment within thirty (30) days after the
         retiring Security Agent's notice of resignation or removal, as the case
         may be, then the retiring Security Agent or the Majority Lenders may,
         on behalf of the Lenders, appoint a successor Security Agent. Upon the
         acceptance of any such appointment by a successor Security Agent, the
         successor shall succeed to and become vested with all the rights,
         powers, privileges and duties of the retiring Security Agent and the
         retiring Security Agent shall be discharged from its duties and
         obligations under this Deed.

5.3      UNFETTERED DISCRETION TO EXERCISE POWERS

         The Security Agent, except as otherwise provided in this Deed, shall,
         as regards all the powers, authorities and discretions vested in it,
         have absolute and unfettered discretion as to the exercise thereof,
         whether in relation to the manner or as to the mode and time for the
         exercise thereof, and in the absence of fraud, it shall be in no way
         responsible for any loss, costs, damages or inconvenience that may
         result from the exercise or non-exercise thereof except if due to its
         wilful misconduct or gross negligence.

5.4      AGENT NOT BOUND TO GIVE NOTICE

         The Security Agent shall not be bound to give notice to any person of
         the execution of this Deed or of the hypothec created under this Deed
         unless and until it shall have been required to do so by the Lenders,
         either directly or through its authorized agent.

5.5      MAY VOTE IN BANKRUPTCY

         In the event of the Grantor making an authorized assignment or a
         custodian, trustee or liquidator in respect of the Grantor's properties
         being appointed under any bankruptcy, insolvency, liquidation or
         reorganization law of any jurisdiction, the Security Agent, acting on
         behalf of the Lenders, may file and prove a claim, value security and
         vote and act at all meetings of creditors and otherwise in such
         proceedings as directed.

5.6      TO ACT ON INSTRUCTIONS OF MAJORITY LENDERS

         The Security Agent shall be obliged to act and shall act and be fully
         protected in acting upon the instructions or directions of the Lender
         or Lenders holding a majority of the then outstanding principal amount
         of the Convertible Notes, provided that, in order to ascertain whether
         the Lender or Lenders giving the instruction or direction to the
         Security Agent hold such majority of the then outstanding principal
         amount of the Convertible Notes, the Security Agent shall be entitled
         to rely, without any independent investigation or inquiry, on any
         certificate or written representation provided to it by the Lender or
         Lenders (the "MAJORITY LENDERS") giving such instruction or direction
         in connection with any proceeding, act, power, right, matter or thing
         relating to or conferred by right or to be done under this Deed, and
         provided further that the obligation of the Security Agent to commence
         or continue any act, action or proceeding under this Deed shall be
         conditional upon the Lenders furnishing, when required, sufficient
         funds to commence or continue such action or proceeding and an
         indemnity reasonably satisfactory to the Security Agent.

5.7      FREE ACCESS TO RECORDS

         shall be obliged to give to the Lenders or to its officers or
         authorized agents, free access to and communication of the Security
         Agent's records relating to these presents and all matters connected
         therewith.

5.8      NO REPRESENTATION OR WARRANTY

         The Security Agent makes no statement, promise, representation or
         warranty whatsoever, and shall have no liability whatsoever, to the
         Lenders as to the authorization, execution, delivery, legality,
         enforceability or sufficiency of this Deed or as to the creation,
         perfection, priority, or enforceability of any hypothecs granted
         hereunder or as to existence, ownership, quality, condition, value or
         sufficiency of any Collateral or as to any other matter whatsoever.

5.9      ACTS BINDING ON LENDERS

         Any modification, amendment, waiver, release, termination or discharge
         of any hypothecs, right, remedy, power or benefit conferred upon the
         Security Agent that is effectuated in a writing signed by the Security
         Agent shall be binding upon all of the Lenders.

         In case of the happening and during the continuance of an Event of
         Default and after the Security Agent has declared the Obligations to be

         upon instructions from the Lenders or the Majority Lenders shall, then
         declare that the security hereby constituted has become enforceable,
         whereupon the security hereby constituted shall become enforceable and
         the Security Agent shall, in addition to any of its other rights,
         forthwith be entitled to enforce the security hereby constituted and in
         that respect, to exercise, for the benefit of the Lenders, any and all
         of the rights provided for in Chapter V of Title III of Book VI of the
         C.C.Q. and in the Code of Civil Procedure of Quebec. In exercising any
         of the rights and recourses available hereunder or at law, the Security
         Agent may, at its option, in respect of all or any part of the
         Collateral, exercise such rights and recourses as are available

         Obligations as being immediately due and payable, without presentment,
         demand, protest or other notice of any kind, all of which are hereby
         expressly waived by the Grantor, anything in this Deed to the contrary
         notwithstanding whereupon such Obligations shall become immediately due

         In the event that any of the security under this Deed becomes
         enforceable, the Lenders (either directly or through an authorized

         Lenders or the Majority Lenders, may waive any default under this Deed,
         unconditionally or upon such terms and conditions as such person shall
         prescribe and may direct the Security Agent to cancel any declaration
         made by it pursuant to the provisions of Section 6.3, provided always
         that no act or omission by the Lenders or the Security Agent with
         respect to any specific default and any security created under this

         If the Security Agent gives the Grantor a prior notice of its intention
         to exercise a hypothecary right the Grantor shall, and shall cause any
         other person in possession of Collateral to, immediately voluntarily
         surrender same to the Security Agent.

6.6      LOCATION OF COLLATERAL

         The Grantor shall disclose to the Security Agent, upon written request

         Agent shall have the right in its discretion to proceed, in the event
         that the security hereby constituted becomes enforceable, in its name
         as Security Agent under this Deed in the enforcement of the security
         created under this Deed and under any remedy provided by any applicable
         law, whether by legal proceedings or otherwise, but it shall not be
         bound to do or take any act or action in virtue of the powers conferred
         on it by this Deed unless and until it shall have been required so to
         do by the Lenders either directly or through its authorized agent,
         defining the action which it is required to take.

6.8      LIMITATION OF LIABILITY

         The Security Agent shall not be responsible or liable, otherwise than
         as a hypothecary creditor holding the power of attorney of the Lenders,
         for any debts contracted by it, for damages to persons or property or
         for salaries or non-fulfilment of contracts during any period wherein
         the Security Agent shall take possession of the Collateral pursuant to
         the terms of any applicable law or this Deed, nor shall the Security
         Agent be liable to account except in respect of amounts actually
         received or be liable for any loss on realization or for any default or
         omission for which a hypothecary or secured creditor might be liable,
         and the Security Agent shall not be bound to do, observe or perform or
         to see to the observance or performance by the Grantor of any of the
         obligations or covenants imposed upon the Grantor under this Deed nor
         in any way to supervise or interfere with the conduct of the Grantor's
         business, unless and until the security created under this Deed has
         become enforceable and the Security Agent shall have become bound to
         enforce the same and shall have been kept supplied with moneys
         reasonably necessary to provide for the expense of the required action.

6.9      PERSONS DEALING WITH THE SECURITY AGENT

         powers which the Security Agent is purporting to exercise have become
         exercisable, or whether any money remains due upon the security of this
         Deed or the Convertible Notes, or as to the necessity or expediency of
         the stipulations and conditions subject to which any sale shall be
         made, or otherwise as to the propriety or regularity of any sale or of
         any other dealing by the Security Agent with the Collateral pursuant to
         the terms of any applicable law or this Deed or to see to the
         application of any money paid to the Security Agent, and, in the
         absence of fraud on the part of such person, such dealing shall be
         deemed, so far as regards the safety and protection of such persons, to
         be within the powers conferred under this Deed and to be valid and
         effectual accordingly.

6.10     POSSESSION NOT REQUIRED

<PAGE>
                                                                              14

9.3      NO OBLIGATION TO MAINTAIN

         To the extent that the Grantor has surrendered or will surrender the
         Collateral or any part thereof to the Security Agent or its agent or if
         the Security Agent or its agent have possession of the Collateral or
         any part thereof, neither the Security Agent nor its agent shall have
         any obligation to continue the use, operation or exploitation of the
         Collateral or any part thereof or to continue the use for which it is
         ordinarily destined or to exercise the rights pertaining to the
         Collateral or any part thereof or to make them productive; and the

         the realization and enforcement of its hypothec.

9.4      USE OF PREMISES

         9.5.1.   together or separately;

         9.5.2.   by auction or by call for tenders;

         9.5.3.   by sale by agreement with purchasers who may include persons

         foregoing shall not preclude the Security Agent from agreeing to or
         making any sale in any other manner not prohibited by law nor shall it
         be interpreted to mean that only a sale made in conformity with the
         foregoing is commercially reasonable or that only the price received at

         commercially reasonable price.

         shall apply in respect of such Claims:

         10.1.1.  The Security Agent hereby authorizes the Grantor to collect
                  when due the capital falling due of, and any revenues of, any
                  Claims until the security hereby constituted shall have become
                  enforceable and the Security Agent shall have given the
                  Grantor a notice withdrawing such authorization, whereupon the
                  Security Agent shall immediately have the right to collect all
                  such capital and revenues. This notice of withdrawal may be
                  given at any time after the security hereby constituted shall
                  have become enforceable, and may be given in respect of all or
                  any part or parts of the Claims.

         10.1.2.  Upon notice of withdrawal by the Security Agent to the
                  Grantor, the Security Agent may require the Grantor to
                  immediately remit to the Security Agent all or a specified
                  part of capital and revenues of Claims received by the Grantor
                  or to deposit the same in one or more designated bank accounts
                  or otherwise to hold, deal with or deliver such capital and
                  revenues, all on such terms and conditions as the Security
                  Agent may specify in such notice.

         10.1.3.  The Security Agent shall have no obligation to exercise any
                  rights in respect of any Claims nor to enforce or to see to
                  payments of the same, whether by legal action or otherwise.
                  After the security hereby constituted shall have become
                  enforceable, the Security Agent may give acquittances for any
                  sums it collects and may, but shall not be obliged to, realize
                  any of the Claims, grant extensions, grant releases, accept
                  compositions, renounce and generally deal with the Claims, and
                  any guarantees or security therefor, and take any action to
                  preserve, protect or secure such Claims, at such times and in
                  such manner as it deems advisable in its sole discretion,
                  without notice to or the consent of the Grantor, and without
                  incurring any liability therefor.

         10.1.4.  Any amounts collected by the Grantor or by the Security Agent
                  or deposited in a designated bank account in respect of the
                  Claims shall form part of the Collateral and be subject to the
                  hypothecs herein created. The Security Agent may, after notice
                  of withdrawal by the Security Agent of the authorization given
                  to the Grantor to collect the Claims as hereinabove provided,
                  apply amounts received by it in respect of the Claims towards
                  payment of all or part of the Obligations even if not yet
                  exigible, including any reasonable fees, costs or other
                  expenses incurred by the Security Agent and secured hereunder,
                  and may impute and apply such amounts towards payment of any
                  part or parts of the Obligations as the Security Agent in its

<PAGE>
                                                                              17

                  sole discretion shall decide, and may change any imputation or
                  application as it sees fit.

         10.1.5.  The Grantor waives any obligation the Security Agent may have
                  to inform the Grantor of any irregularity in the payment of
                  any sums exigible on any claims or rights.

11.      OTHER SECURITY

11.1     It is expressly declared and agreed between the parties hereto that the
         security hereby granted is in addition to and over and above any and
         all other security now or hereafter held by the Security Agent or any
         of the Lenders for the Obligations and any part or parts thereof.
         Without in any way limiting the generality of the foregoing, the
         present security shall not be diminished or novated or otherwise
         affected by any other security or any promissory note or other evidence
         of indebtedness which the Security Agent may have heretofore obtained
         or may hereafter obtain from the Grantor or from any other person, or
         by any other agreement which the Grantor and the Security Agent may
         have heretofore entered into or may hereafter enter into, nor shall any
         such security or note or evidence of indebtedness or agreement be
         diminished or novated or otherwise affected hereby.

12.      TIME OF THE ESSENCE

12.1     Is it understood and agreed by the Grantor and the Security Agent that
         in addition to any other circumstances where the Grantor is in default
         by operation of law, time is of the essence in this Deed and that the
         mere lapse of time shall have the effects contemplated by the present
         Deed, without the necessity of further notice or delay, in accordance
         with Article 1594 of the C.C.Q.

13.      SEVERABILITY

13.1     If any clause of the present Deed, or any part thereof, is null or
         otherwise unenforceable, without effect, or deemed unwritten, such
         clause shall be considered separate and severable from this Deed and
         the remaining provisions hereof shall continue in full force and
         effect.

14.      WAIVER

14.1     The Security Agent may, with the consent of the Majority Lenders, grant
         extensions of time and other indulgences and give up security, accept
         compositions, compromise, settle, grant releases and discharges and
         otherwise deal with the Grantor or debtors of the Grantor, sureties and
         others and with the Collateral and other security as the Security Agent
         may see fit without prejudice to the liability of the Grantor or the
         rights of the Security Agent to hold and realize the hypothecs created
         pursuant to the present Deed. Furthermore, the Security

                                                                              18

         Agent may, after the security hereby constituted has become
         enforceable, demand, collect and sue on Collateral in either the
         Grantor's or the Security Agent's name, at the Majority Lenders' or the
         Security Agent's option, and may endorse the Grantor's name on any and
         all cheques, commercial paper and any other instruments pertaining to
         or constituting Collateral.

14.2     No act, delay or omission by the Security Agent in exercising any right
         or remedy hereunder or with respect to any Obligations or Accessories
         shall operate or be construed as a waiver thereof or of any other right
         or remedy and no waiver of any provision hereof shall be effective
         unless in writing.

15.      AMENDMENTS

15.1     No modification, variation or amendment of any provision of this Deed
         shall be made except by written agreement executed by the parties
         hereto.

         Subject to and upon the Lenders confirming the repayment and
         fulfillment and performance in full of the Obligations, the Security
         Agent shall (within a reasonable time after it receives from the
         Grantor a written request for release of the Collateral) execute and
         deliver to the Grantor an instrument in form and substance satisfactory
         to the Security Agent releasing (without recourse, without warranty,
         and without any liability whatsoever) any and all hypothecs and other
         security the Security Agent may then hold in the Collateral and
         thereupon the Security Agent shall, at the Grantor's expense, execute
         and deliver to the Grantor such deeds and other documents as the
         Grantor may reasonably request to evidence such release and effect the
         cancellation of any publication hereof.

16.2     All acquittances and other deeds to which the Security Agent may become
         party shall be approved by the legal advisors of the Lenders, the whole
         at the Grantor's expense.

17.      NOTICES

17.1     All communications provided for or permitted hereunder shall be given

         conflict with any term, condition or provision of any of the
         Convertible Notes, the relevant term, condition or provision of such

         inconsistency save and except in respect of the provisions of this Deed
         which relate to the creation and enforcement of the hypothecs hereby
