     6.2.2 dispose of any of the Collateral likely to perish or to rapidly
     depreciate or decrease in value;

     6.2.3 fulfil any of the undertakings of the Company relating to the
     Collateral;

     6.2.4 use, administer and exercise any right pertaining to the Collateral;

     6.2.5 use the premises where the Collateral is located; and/or

     6.2.6 exercise any right attached to the shares or other securities

                                 -14-

6.4  If, at any time, the Agent has possession of the Collateral, it shall have
no obligation to maintain the use for which the Collateral is normally
intended, to make it productive nor to continue its use or operation. The Agent
shall not be bound to make an inventory, to take out insurance or to furnish
any other security. Where the Collateral is in the possession of the Agent, the
Company shall be deemed to have surrendered such Collateral, if, within the
delays granted by law or by a tribunal to surrender the Collateral, the Agent
has not received written notice from the Company to the effect that it is
opposed to the exercise of the hypothecary recourse set forth in the prior
notice.

6.5  In the event of a waiver by the Agent of its recourses, hypothec or other
rights against the Collateral, the Agent may, in its discretion, if the
Collateral has been surrendered to it, return the remaining Collateral to the
Company, without any warranty or representation, express, tacit or implied, on
the part of the Agent, but without prejudice to the other rights and recourses
of the Agent or the Debentureholders.

6.6  In the event the Agent exercises its hypothecary recourse of taking in
payment and the Company requires the Agent to sell the Collateral, the Company
acknowledges that the Agent shall not be disturbed in, or required to renounce
to or abandon, its recourse of taking in payment unless, before the expiration
of the time limit to surrender, the Agent (i) shall have received security,
which it deems satisfactory, to the effect that the sale will be made at a
price high enough for the Debentureholders and the Agent to be paid their debt
in full, (ii) shall have been reimbursed the costs incurred by it and (iii)
shall have been advanced all amounts necessary for the sale of the Collateral.

6.7  In the event that, during the enforcement of the security created
hereunder, the Agent sells the Collateral, the Agent will not be required to
obtain a prior appraisal from a third party.

6.8  The Company agrees that in the event of a public sale or other sale of the
Collateral, following the enforcement of the security created hereunder, the
Agent and any Debentureholder shall, to the extent permitted by law, have the
right to purchase the whole or any part of the Collateral so sold free of any
rights, including any right of redemption by the Company, which rights are
hereby waived and released by the Company.

6.9  While exercising its right to sell the Collateral, the Agent may choose to
sell the Collateral with legal warranty or with complete or partial exclusion
of such warranty.

     successors from the Company, except in the case of the Canadian Collateral
     Agent or any Canadian Lender, to the extent such expense, loss, or damage

     applicable Governmental Authority when due all Canadian withholding taxes
     exigible in respect of any transfers from the Blocked Accounts (or any

     Canadian Collection Account. Upon request from the Canadian Collateral
     Agent, the Company shall provide to the Canadian Collateral Agent the
     original or a certified copy of a receipt evidencing such payment or, if
     such taxes are not exigible on any such transfer, a reasonably detailed
     explanation (with reference to the type of intercompany transaction to
     which the transfer/payment relates) therefor.

Agent to be its irrevocable mandatary in accordance with the Civil Code with

irrevocable until the release or discharge of the security created under this
Deed but shall not be exercised by the Agent unless an Event of Default has
occurred and is continuing.

transfer, and to record any assignment, license or transfer of, the
Intellectual Property. This mandate is irrevocable until the release or
discharge of the security created under this Deed.

10.  LICENCE AGREEMENTS

10.1 The Company Remains Liable. Notwithstanding any other provision in this
Deed and the other Loan Documents, the Company shall remain liable under all
Licence Agreements. The Company shall perform all of its duties and obligations
thereunder just as if this Deed had not been executed. The Company shall not be
released from any of its duties or obligations under the Licence Agreements by
the exercise of any rights by the Agent. The Agent shall not have any
obligation or liability under the Licence Agreements by reason of this Deed,
nor shall the Agent be obliged to perform any of the obligations or duties of
the Company thereunder or to take any action to collect or enforce any claim
for payment assigned or hypothecated hereunder. The rights and powers conferred
on the Agent hereunder are solely to protect its interest in the Collateral and
shall not impose any duty upon it to exercise any such powers.

11.  THE AGENT

11.1 The Agent shall hold the hypothec granted pursuant to this Deed for the
benefit of the Debentureholders and shall act as their agent in the exercise of
the rights conferred hereunder. The Agent shall be considered a "fonde de
pouvoir" of the Debentureholders within the meaning of Article 2692 of the
Civil Code. The Agent may perform any act necessary to the performance of its
duties.

11.2 Any person who becomes a Debentureholder shall benefit from the provisions
hereof and the appointment of the Agent as agent for the Debentureholders and,
upon becoming a Debentureholder, irrevocably authorizes the Agent to perform
such functions. Each Debentureholder, by its acceptance thereof (a)
acknowledges that the first issue of a Debenture has been or may be purchased
from the Company by the Agent, by underwriting, purchase, subscription or
otherwise and (b) waives any right it may have under Section 32 of the Act
respecting the special powers of legal persons.
<PAGE>

                                     -22-

Agent (unless the Agent is also the sole Debentureholder).

11.4 The Agent shall have the right to proceed in its name as Agent hereunder
in the enforcement of the security hereby constituted by any remedy provided by
law. The Agent may, before exercising any remedy, require the Debentureholders
to deposit the Debentures with the Agent, for which Debentures the Agent shall
issue a receipt. The obligation of the Agent to exercise any remedy shall be
conditional upon the Debentureholders furnishing the Agent, when required in
writing by the latter, sufficient funds for such purpose and an indemnity which
the Agent considers reasonable to cover the Agent against any costs, expenses,
borrowings, advances and fees of the Agent and against all liability which the
Agent may incur.

11.5 No person dealing with the Agent or its agents need inquire whether the
security hereby constituted has become enforceable or whether the powers which
the Agent is purporting to exercise have become exercisable.

11.6 The Agent is only required to exercise reasonable care in the exercise of
its rights and the performance of its obligations and, in any event, is only
liable for its intentional fault or gross negligence.

11.7 The Agent may delegate the exercise of its rights or the performance of
its obligations hereunder to another person including a Debentureholder. In
that event, the Agent may furnish that person with any information it may have
concerning the Company or the Collateral. The Agent shall not be responsible
for damages resulting from such delegation or from any fault committed by such
delegate.

11.8 The rights of the Agent hereunder shall benefit any successor of the
Agent, including any person resulting from the amalgamation of the Agent with
any other person.

11.9 The Agent shall be under no duty to take any discretionary action
permitted to be taken by it hereunder or pursuant to applicable law.

11.10 The Agent may exercise all of its rights hereunder without possession of
the Debentures and without having to produce same in support of any judicial
proceeding or trial in connection therewith.

11.11 The Agent may at any time resign hereunder upon not less than thirty (30)
days notice in writing to the Company and to the Debentureholders or upon such
shorter notice as the Debentureholders may accept; the Debentureholders may
then appoint a new agent. The
<PAGE>

                                     -23-

Debentureholders may also remove the Agent and appoint a new agent in its place
and stead, upon not less than thirty (30) day notice in writing to the Agent
and to the Company. Such new agent, without further act, shall be vested with
and have the rights and powers granted to the Agent hereunder and shall be
subject in all respects to the conditions and provisions hereof.
