               applicable protective order or equivalent.

        (b)    The Manager shall take reasonable security precautions, at least

               Information, as defined hereinabove.

        (c)    Confidential Information and Materials may be disclosed,

               reasonable manner to aid the Company to regain possession of said

               further unauthorized use.

        (b)    The Manager shall return all originals, copies, reproductions and
               summaries of or relating to the Confidential Information at the

        (c)    The parties hereto recognize that a breach by the Manager of any

behalf of Debtor or any of its Subsidiaries to Secured Party in connection with
the Termination Agreement, Secured Promissory Note and this Agreement, and all
certificates and documents delivered to Secured Party pursuant to the terms
thereof do not contain as of the date furnished any untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements contained herein or therein, in light of the circumstances under
which they were made, not misleading.

        (b)    the Debtor is in breach of any term, condition, obligation or

               be dissolved, wound-up, reorganized, or declared bankrupt or
               insolvent (for purposes of this Agreement the term "insolvent"
               means (i) that the liabilities of Debtor exceed its assets, or
               (ii); Debtor is unable to pay its obligations as they mature in
               the ordinary course of its business operations.)

               Debtor or any part of the Collateral;

        (f)    any execution, sequestration, extent, or any other process of any

               Debtor creates or permits to exist any charge, encumbrance or
               lien on, or claim against or any security interest in, any of the
               Collateral which ranks or could in any event rank in priority to
               or pari passu with any security interest or charge created by
               this Security Agreement with the exception of the security
               interests listed in Schedule "A" hereto;

<PAGE>
                                      -10-

        (h)    the holder of any other charge, encumbrance or lien on, or claim
               against, or security interest in, any of the Collateral does

               claim or security interest;

               amalgamation, merger or other similar arrangement with any other
               person.

11.            ENFORCEMENT

11.1           Upon any Default under this Security Agreement, the Secured Party
may declare any or all of the Obligations not payable on demand to become
immediately due and payable and the security hereby constituted will immediately
become enforceable. To enforce and realize on the security constituted by this
Security Agreement the Secured Party may take any action permitted by law or in
equity, as it may deem expedient, and in particular without limiting the
generality of the foregoing, the Secured Party may do any of the following:

        (a)    appoint by instrument a receiver, receiver and manager or a
               receiver-manager (the person so appointed is hereinafter called
               the "Receiver") of the Collateral, with or without bond as the
               Secured Party may determine, and from time to time in its
               absolute discretion remove such Receiver and appoint another in
               its stead;

        (b)    enter upon any premises of the Debtor and take possession of the
               Collateral with power to exclude the Debtor, its agents and its
               servants therefrom, without becoming liable as a mortgagee in
               possession;

        (c)    preserve, protect and maintain the Collateral and make such
               replacements thereof and repairs and additions thereto as the
               Secured Party may deem advisable;

        (d)    sell, lease or otherwise dispose of all or any part of the
               Collateral, whether by public or private sale or lease or
               otherwise, in such manner, at such price as can be reasonably
               obtained therefor and on such terms as to credit and with such
               conditions of sale and stipulations as to title or conveyance or
               evidence of title or otherwise as to the Secured Party may seem
               reasonable, provided that if any sale is on credit the Debtor
               will not be entitled to be credited with the proceeds of any such
               sale, lease or other disposition until the moneys therefor are
               actually received; and

        (e)    exercise all of the rights and remedies of a secured party under
               the Act.

11.2           A Receiver appointed pursuant to this Security Agreement will be
the agent of the Debtor and not of the Secured Party and, to the extent
permitted by law or to such lesser extent permitted by its appointment, will
have all the powers of the Secured Party hereunder, and in addition will have
power to carry on the business of the Debtor and for such purpose from time to
time to borrow money either secured or unsecured, and if secured by a security
interest on any of the Collateral; such security interest may rank before or
pari passu with or behind any security

<PAGE>
                                      -11-

interest created by this Security Agreement, and if it does not so specify such
security interest will rank before the security interests created by this
Security Agreement.

11.3           All amounts realized from the disposition of Collateral pursuant
to this Security Agreement will be applied as the Secured Party, in its absolute
discretion, may direct as follows:

        (a)    in payment of all costs, charges and expenses (including legal
               fees and disbursements on a solicitor and his own client basis)
               incurred by the Secured Party in connection with or incidental
               to:

               (i)    the exercise by the Secured Party of all or any of the
                      powers granted to it pursuant to this Security Agreement;
                      and

               (ii)   the appointment of the Receiver and the exercise by the
                      Receiver of all or any of the powers granted to it
                      pursuant to this Security Agreement, including the
                      Receiver's reasonable remuneration and all outgoings
                      properly payable by the Receiver;

        (b)    in or toward payment to the Secured Party of all principal and
               other moneys (except interest) due in respect of the Obligations;
               and

        (c)    in or toward payment to the Secured Party of all interest
               remaining unpaid in respect of the Obligations.

Subject to applicable law and the claims, if any, of other creditors of the
Debtor, any surplus will be paid to the Debtor.

12.            DEFICIENCY

12.1           If the amounts realized from the disposition of the Collateral
are not sufficient to pay the Obligations in full the Debtor will immediately
pay to the Secured Party the amount of such deficiency.

13.            RIGHTS CUMULATIVE

13.1           All rights and remedies of the Secured Party set out in this
Security Agreement are cumulative and no right or remedy contained herein is
intended to be exclusive but each will be in addition to every other right or
remedy contained herein or in any existing or future security agreement or now
or hereafter existing at law, in equity or by statute, or pursuant to any other
agreement between the Debtor and the Secured Party that may be in effect from
time to time.

14.            LIABILITY OF SECURED PARTY

14.1           The Secured Party will not be responsible or liable for any debts
contracted by it, for damages to persons or property or for salaries or
non-fulfilment of contracts during any period when the Secured Party shall
manage the Collateral upon entry, as herein provided, nor will the Secured Party
be liable to account as mortgagee in possession or for anything except

<PAGE>
                                      -12-

actual receipts or be liable for any loss on realization or for any default or
omission for which a mortgagee in possession may be liable. The Secured Party
will not be bound to do, observe or perform or to see to the observance or
performance by the Debtor of any obligations or covenants imposed upon the
Debtor nor will the Secured Party, in the case of securities, instruments or
chattel paper, be obliged to preserve rights against other persons, nor will the
Secured Party be obliged to keep any of the Collateral identifiable. The Debtor
hereby waives any applicable provision of law permitted to be waived by it which
imposes higher or greater obligations upon the Secured Party than aforesaid.

15.            APPOINTMENT OF ATTORNEY

15.1           Debtor appoints the Secured Party, the Secured Party's designee
or the Receiver as its attorney-in-fact to endorse Debtor's name on any checks,
notes, acceptances, money orders, drafts or other forms of payment or security
that may come into the Secured Party or its designee's possession; to sign
Debtor's name on any document relating to any Accounts, on drafts against
Debtors, on schedules and assignments of Accounts, on notices of assignment and
other public records, on verifications of Accounts and on notices to Debtors; to
notify post office authorities to change the address for delivery of Debtor's
mail to an address designated by the Secured Party or its designee, to receive
and open all mail addressed to Debtor and to retain all mail relating to
Collateral and forward all other mail to Debtor; and to do all things necessary
to carry out or enforce this Agreement. Debtor ratifies and approves all acts of
the Secured Party or its designee as attorney-in-fact. The Secured Party, or its
designee, as attorney-in-fact, will not be liable for any acts or omissions, or
for any error of judgment or mistake of fact or law, except for bad faith. This
power, being coupled with an interest, is irrevocable until all Obligations have
been fully satisfied; provided that neither the Secured Party or its designee
will exercise this power until after a Default.

16.            ACCOUNTS

16.1           Notwithstanding any other provision of this Security Agreement,
the Secured Party may collect, realize, sell or otherwise deal with the Accounts
or any part thereof in such manner, upon such terms and conditions and at such
time or times, whether before or after default, as may seem to be advisable, and
without notice to the Debtor, except in the case of disposition after default
and then subject to the provisions of Part V of the Act. All moneys or other
forms of payment received by the Debtor in payment of any Account will be
received and held by the Debtor in trust for the Secured Party.

17.            APPROPRIATION OF PAYMENTS

17.1           Any and all payments made in respect of the Obligations from time
to time and moneys realized from any security interests held therefor (including
moneys collected in accordance with or realized on any enforcement of this
Security Agreement) may be applied to such part or parts of the Obligations as
the Secured Party may see fit, and the Secured Party may at all times and from
time to time change any appropriation as the Secured Party may see fit.

                                      -13-

18.            LIABILITY TO ADVANCE

18.1           None of the preparation, execution, perfection and registration
of this Security Agreement or the advance of any moneys will bind the Secured
Party to make any advance or loan or further advance or loan, or renew any note
or extend any time for payment of any indebtedness or liability of the Debtor to
the Secured Party.

19.            WAIVER

19.1           The Secured Party may from time to time and at any time waive in
whole or in part any right, benefit or default under any clause of this Security
Agreement but any such waiver of any right, benefit or default on any occasion
will be deemed not to be a waiver of any such right, benefit or default
thereafter, or of any other right, benefit or default, as the case may be.

20.            NOTICE

20.1           Notice may be given to either party by sending it through the
post in prepaid mail or delivered to the party for whom it is intended, at the
principal address of such party provided herein or at such other address as may
be given in writing by such party to the other, and any notice if posted will be
deemed to have been given at the expiration of three business days after posting
and if delivered, on delivery.

21.            EXTENSIONS

21.1           The Secured Party may grant extensions of time and other
indulgences, take and give up security, accept compositions, compound,
compromise, settle, grant releases and discharges, refrain from perfecting or
maintaining perfection of security interests, and otherwise deal with the
Debtor, account debtors of the Debtor, sureties and others and with the
Collateral and other security interests as the Secured Party may see fit without
prejudice to the liability of the Debtor or the Secured Party's right to hold
and realize on the security constituted by this Security Agreement.

22.            NO MERGER

22.1           This Security Agreement will not operate so as to create any
merger or discharge of any of the Obligations, or any assignment, transfer,
guarantee, lien, contract, promissory note, bill of exchange or security
interest of any form held or which may hereafter be held by the Secured Party
from the Debtor or from any other person whomsoever. The taking of a judgment
with respect to any of the Obligations will not operate as a merger of any of
the covenants contained in this Security Agreement.

23.            ASSIGNMENT

23.1           The Secured Party may, without further notice to the Debtor, at
any time assign, transfer or grant a security interest in this Security
Agreement and the security interests granted hereby. The Debtor expressly agrees
that the assignee, transferee or secured party, as the case may be, will have
all of the Secured Party's rights and remedies under this Security Agreement

<PAGE>
                                      -14-

and the Debtor will not assert any defence, counterclaim, right of set-off or
otherwise any claim which it now has or hereafter acquires against the Secured
Party in any action commenced by such assignee, transferee or secured party, as
the case may be, and will pay the Obligations to the assignee, transferee or
secured party, as the case may be, as the Obligations become due.

24.            SATISFACTION AND DISCHARGE

24.1           Any partial payment or satisfaction of the Obligations, or any
ceasing by the Debtor to be indebted to the Secured Party, will be deemed not to
be a redemption or discharge of this Security Agreement. The Debtor will be
entitled to a release and discharge of this Security Agreement upon full payment
and satisfaction of all Obligations and upon written request by the Debtor.

25.            ENUREMENT

25.1           This Security Agreement will enure to the benefit of the Secured
Party and its successors and assigns, and will be binding upon the respective
heirs, executors, personal representatives, successors and permitted assigns of
the Debtor.

                      acquired, or received by a Person of whatever kind and
                      however evidenced; and

               (iii)  any right, title, and interest in a Person's Goods which

<PAGE>
                                      -15-

                      (C)    any rights a Person has in such sold, leased, or

               presently has or may hereafter have any claim, that presently or
               may hereafter be existing or maintained with, issued by, drawn

               above; and all books and records (including computer programs,
               tapes and data processing software) evidencing an interest in or
               relating to the above.

        (g)    "Debtor" and the personal pronoun "it" or "its" and any verb
               relating thereto and used therewith will be read and construed as
               required by and in accordance with the context in which such
