pursuant  to  a  drawing under any LC calculated on the amount drawn, based upon

amount available under any LC has not been drawn prior to the expiry of such LC,
the  Borrower  shall  pay  an  LC  fee  calculated  on  the

currency,  RBUSBR  plus  5%  per  annum.

Equivalent  Yearly  Rates
- -------------------------
The annual rates of interest or fees to which the rates calculated in accordance
with  this  agreement  are equivalent, are the rates so calculated multiplied by

of  default,  maturity  date,  demand  and  judgement.

EXCHANGE  RATE  FLUCTUATIONS

conclusive  evidence of the indebtedness of the Borrower to the Bank pursuant to
this  agreement.

The  Borrower  authorizes  and  directs  the  Bank  to  automatically  debit, by

Potential  Prior-Ranking  Claims

The Borrower hereby grants its consent (such grant to remain in force as long as

having  information relating to any Potential Prior-Ranking Claim arising by any

hereto.

Amendments  and  Waivers
- ------------------------
No  amendment  or  waiver  of  any provision of this agreement will be effective
unless  it  is  in  writing  signed  by the Borrower and the Bank. No failure or
delay,  on  the  part of the Bank, in exercising any right or power hereunder or

Severability
- ------------
If  any provision of this agreement is or becomes prohibited or unenforceable in
any  jurisdiction,  such prohibition or unenforceability shall not invalidate or
render  unenforceable  the  provision  concerned  in  any other jurisdiction nor
invalidate,  affect or impair any of the remaining provisions of this agreement.

Life  Insurance  Options
- ------------------------
The  Borrower  acknowledges  that  Borrowings  are  not insured under the Bank's
Business  Loan Insurance  Plan.

Judgement  Currency
- -------------------
If  for the purpose of obtaining judgement in any court in any jurisdiction with
respect  to this agreement, it is necessary to convert into the currency of such
jurisdiction (the "Judgement Currency") any amount due hereunder in any currency
other  than the Judgement Currency, then conversion shall be made at the rate of
exchange  prevailing  on  the  Business Day before the day on which judgement is
given.  For  this  purpose  "rate  of  exchange"  means  the  rate  at which the
Bank  would,  on the relevant date, be prepared to sell a similar amount of such
currency in the Toronto foreign exchange market, against the Judgement Currency,
in  accordance  with  normal  banking  procedures.

In  the  event that there is a change in the rate of exchange prevailing between
the  Business  Day  before  the  day on which judgement is given and the date of
payment  of  the amount due, the Borrower will, on the date of payment, pay such
additional  amounts  as  may be necessary to ensure that the amount paid on such
date  is  the amount in the Judgement Currency which, when converted at the rate
of exchange prevailing on the date of payment, is the amount then due under this
agreement  in  such  other  currency  together with interest at RBP and expenses
(including  legal  fees  on a solicitor and client basis). Any additional amount
due  from  the  Borrower  under  this section will be due as a separate debt and
shall  not  be affected by judgement being obtained for any other sums due under
or  in  respect  of  this  agreement.

Governing  Law
- --------------
This agreement shall be construed in accordance with and governed by the laws of
the  Province of  Ontario  and  of  Canada  applicable  therein.

Whole  Agreement
- ----------------
This  agreement, the security and any other written agreement delivered pursuant
to  or  referred  to in this agreement constitute the whole and entire agreement
between  the  parties  in  respect of the Credit Facilities. There are no verbal
agreements,  undertakings  or  representations  in  connection  with  the Credit
Facilities.

Joint  and  Several
- -------------------
Where more than one Person is liable as Borrower or Guarantor for any obligation
under this agreement, then the liability of each such Person for such obligation
is  joint  and  several  with  each  other  such  Person.

Counterpart  Execution
- ----------------------

parties in separate counterparts, each of which when so executed shall be deemed

instrument.

                             FEF  CONTRACTS  SCHEDULE


FEF  CONTRACT  DEFINITIONS
- --------------------------

"FOREIGN  EXCHANGE FORWARD CONTRACT" or "FEF CONTRACT" means a currency exchange
transaction  or agreement or any option with respect to any such transaction now
existing  or  hereafter  entered  into  between  the  Borrower  and  the  Bank;


CONDITIONS  APPLICABLE  TO  FEF  CONTRACTS
- ------------------------------------------

At  the  Borrower's request, the Bank may agree to enter into FEF Contracts with
the Borrower from time to time. The Borrower acknowledges that the Bank makes no
formal commitment herein to enter into any FEF Contract and the Bank may, at any
time and at all times, in its sole and absolute discretion, accept or reject any
request  by  the  Borrower  to enter into a FEF Contract. If the Bank does enter
into  a  FEF Contract with the Borrower, it will do so subject to the following:

(a)  the  Borrower shall promptly issue or countersign and return a confirmation
     or  acknowledgement  of  the terms of each such FEF Contract as required by
     the  Bank;

(b)  the  Borrower shall, if required by the Bank, promptly enter into a Foreign
     Exchange  and  Options Master Agreement or such other agreement in form and
     substance  satisfactory  to  the  Bank  to  govern  the  FEF  Contract(s);

(c)  in  the  event  of  demand  for  payment  under the agreement of which this
     schedule  forms a part, the Bank may terminate all or any FEF Contracts. If
     the  agreement  governing  any  FEF  Contract  does  not contain provisions
     governing termination, any such termination shall be effected in accordance
     with  customary  market practice. The Bank's determination of amounts owing
     under  any  terminated  FEF  Contract shall be conclusive in the absence of
     manifest  error.  The  Bank shall apply any amount owing by the Bank to the
     Borrower  on  termination  of  any  FEF  Contract  against  the  Borrower's
     obligations  to  the  Bank  under the agreement and any amount owing to the
     Bank  by  the Borrower on such termination shall be added to the Borrower's
     obligations  to  the  Bank  under  the  agreement and secured by the Bank's
     security;

(d)  the  Borrower  shall  pay  all  required  fees  in  connection with any FEF
     Contracts  and  indemnify and hold the Bank harmless against any loss, cost
     or  expense incurred by the Bank in relation to any FEF Contract, including
     without  limitation,  the  costs  of  terminating  or  cancelling  any  FEF
     Contract;

(e)  any  rights  of  the  Bank  herein  in  respect  of any FEF Contract are in
     addition  to and not in limitation of or substitution for any rights of the
     Bank  under  any  agreement  governing such FEF Contract. In the event that
     there  is  any  inconsistency  at any time between the terms hereof and any
     agreement  governing  such  FEF Contract, the terms of such agreement shall
     prevail;  and

(f)  in addition to any security which may be held at any time in respect of any
     FEF Contract, upon request by the Bank from time to time, the Borrower will
     deliver  to  the  Bank  such  security  as  is  acceptable  to  the Bank as
     continuing  collateral  security for the Borrower's obligations to the Bank
     in  respect  of  FEF  Contracts.

paid by each party hereto to each of the other parties hereto and other good and
valuable  consideration  (the  receipt  and  sufficiency  of  which  is  hereby
acknowledged  by  the  parties)  it  is  agreed  as  follows:

             ARTICLE ONE     - POSTPONEMENT OF BRASCAN INDEBTEDNESS

1.1     Except  as specifically set out in this Agreement, the agreements herein
are  not intended to nor will they impair the obligations of any of the Obligors
as  applicable,  to  pay  the  Lender's  Indebtedness  or  to  pay  the  Brascan
Indebtedness,  including  the principal thereof and the interest thereon, as and
when  the  same shall become due and payable in accordance with the terms of the
Lender's  Obligations  and the Brascan Obligations, as the case may be, nor will
anything  in  this  Agreement prevent the holder of the Lender's Security or the
Brascan  Security from exercising all remedies otherwise permitted by applicable
law  upon  the  occurrence  of  a  default  under  such  security.

1.2     Each  of the Lender and Brascan hereby agree that if the Lender provides
written  notice  to  Brascan  of  the  Lender  issuing  a demand pursuant to the
Lender's  Obligations  (a  "DEMAND NOTICE"), Brascan shall cease to receive, and
will postpone receipt of all payments in respect of the Brascan Indebtedness and
shall  not  be  entitled  to  accelerate  the  time  for  payment of any Brascan
Indebtedness,  enforce any rights under the Brascan Obligations, petition any of
the  Obligors,  as the case may be, into bankruptcy (or otherwise participate in
or  initiate  any  similar proceeding under the Companies Creditors Arrangements
Act  or  similar  insolvency  legislation)  or  initiate  any proceeding for the
payment  of  any  Brascan  Indebtedness  until  the  earliest  of the following:
(i)     the  date which is ninety (90) days following the date on which a Demand
Notice is issued (such period of time being the "POSTPONEMENT PERIOD"); provided
that  if  Postponement  Periods  of 120 days or more have already been in effect
during  the 365 days preceding the date on which a Demand Notice is issued, then
the  period  under  this  clause  (i)  shall  be  deemed  to  be seven (7) days;
(ii)     the  date  on  which  a  Lender-issued  Notice  of Intention to Enforce
Security  pursuant  to  the  Bankruptcy  and  Insolvency  Act  (Canada)  becomes
effective;  and
(iii)     the date on which the Lender's Priority Indebtedness is repaid in full
and  the  Lender  has provided written confirmation of same to Brascan (of which
the  Lender  covenants  to  provide  forthwith  upon  request).

1.3     If  Brascan  receives  any payment or amount from any of the Obligors or
any  third  party  on  account  of  the  Brascan  Indebtedness  contrary  to the
provisions  of  this  Agreement,  any  such  payment  or amount shall be held by
Brascan  in  trust for the Lender and shall be forthwith paid over to the Lender
on  account  of  the  Lender's  Priority  Indebtedness.


               ARTICLE TWO     - SUBORDINATION OF BRASCAN SECURITY

2.1     SUBORDINATION  OF  SECURITY.  Brascan  agrees  with  the Lender that the
Brascan  Security  with respect to the Subordinated Assets shall rank subsequent
and be subordinate to the Lender's Security to the extent of all of the Lender's
Priority  Indebtedness secured notwithstanding the time or order of registration
or  filing of financing statements, the date or dates of any advance or advances
by  the  Lender  and  Brascan,  the  date  or dates of any default by any of the
Obligors,  as  applicable,  or  the  date  or dates of taking any enforcement or
realization  measures  or  proceedings;  provided  that  the  Lender agrees with
Brascan  that, to the extent of any Lender's Indebtedness exceeding the Lender's
Priority  Indebtedness,  the  Lender's Security with respect to the Subordinated
Assets  shall  rank subsequent and be subordinate to the Brascan Security to the
extent  of  all  of  the  Brascan  Indebtedness.

2.2     EXTENSION OF PRIORITY.  The priority to which the Lender and Brascan are
entitled  hereunder  shall  extend  to  all  books, accounts, invoices, letters,
papers,  documents  and  other  records in any form relating to the Subordinated
Assets,  all contracts, securities, instruments and other rights and benefits in
respect  thereof,  all  substitutions  and  replacements thereof, and increases,
additions,  and  accessions  thereto, all proceeds therefrom, and any insurance,
indemnity  or  compensation  for  loss  of or damage to the Subordinated Assets.

2.3     DISTRIBUTION  OF PROCEEDS.  The proceeds resulting from the enforcements
or  realization  of any of the mortgages, charges, assignments or other security
interests  contained  in  or  constituted  by  the  Brascan Security or Lender's
Security  and  all  other proceeds received by Brascan or the Lender pursuant to
the  Brascan  Security  or  the Lender's Security, including without limitations
insurance and expropriation proceeds, will be divided or otherwise dealt with in
such  a  way  as  to  give  effect  to  the provisions of this agreement and the
priorities  created  and  established  hereby.

2.4     Prior  to  making any demand on any of the Obligors, as the case may be,
for  repayment  of  any  funds  owed, the Lender or Brascan, as the case may be,
shall  provide  the  other  three (3) business days prior notice of such demand,
provided, however, that if the Lender or Brascan, as the case may be, determines
in  good  faith  that any delay in demanding payment would be prejudicial to it,
such  notice  need  only  be  given at the time that demand for payment is made.
Neither  the  Lender  nor Brascan shall be liable for any accidental omission to
provide  notice  to the other of them as required pursuant to this section.  For
greater  certainty  and  without  limiting  the generality of the foregoing, any
failure  by  the Lender to provide notice hereunder shall not impair or restrict
its  right  as against any of the Obligors, as applicable, to make demand at any
time  in  its  sole  discretion.

2.5     The  Lender  shall  have  no  obligation  to Brascan with respect to any
monies  in any account of any of the Obligors, as the case may be, maintained at
the  Lender,  or  any  monies  deposited  in or disbursed from any such account,
unless  the  Lender  has received notice from Brascan as provided for in Section
2.4  of  this  Agreement.





      ARTICLE THREE     - CONSENT TO LENDER'S SECURITY AND BRASCAN SECURITY

3.1     CONSENT  AND  INSURANCE.  Notwithstanding  the terms of any agreement or
instrument  establishing  or  related  to  the  Lender's Security or the Brascan
Security,  Brascan  hereby consents to the creation and issuance of the Lender's
Security  and  the  Lender  hereby  consents to the creation and issuance of the
Brascan  Security.  Brascan and the Lender each consent to the other being named
as a loss payee on any policy of insurance now or hereafter held by any Obligor,
as  applicable,  in  respect  of  its  assets and undertaking, provided that the
proceeds  of  any  such  policy shall be payable in accordance with the terms of
this  Agreement.

            ARTICLE FOUR     - CONSENT AND AGREEMENT OF THE OBLIGORS

4.1     OBLIGORS' COVENANT.  Each Obligor irrevocably and unconditionally agrees
with  the  Lender  and  Brascan  that  so  long as the Lender's Indebtedness and
Brascan  Indebtedness  are outstanding and are secured by the Lender's Security,
and  Brascan  Security, it will (i) make all payments in respect to the Lender's
Indebtedness  and  the Brascan Indebtedness in accordance with the terms of this
Agreement,  (ii) consent to any exchange of information in respect to any of the
Obligors,  as applicable, by and between Brascan and the Lender, and (iii) stand
possessed  of  its assets thereby secured and maintain and deal with such assets
in  accordance  with  the  priorities  herein  set  out.

4.2     NO  CHALLENGE.  None  of  the  parties hereto, as the case may be, shall
directly or indirectly take any action or consent to the taking of any action or
otherwise  assist  any person to challenge the validity, legality, perfection or
priority  of  the Lender's Security or the Brascan Security, as the case may be.

                        ARTICLE FIVE     - CROSS DEFAULT

5.1     CROSS-DEFAULT.  The  parties  agree  that  any and all default under the
terms  and  conditions  of the said Brascan Security shall constitute concurrent
default  under  the Lender's Security and any and all default under the Lender's
Security  shall  constitute  concurrent  default  under  the  Brascan  Security,
whereupon  the  unpaid  principal  amount  of  the  Lender's Indebtedness or the
Brascan  Indebtedness  together  with interest and costs shall, at the option of
and  upon  demand  by the Lender or Brascan, become immediately due and payable.

5.2     LENDER'S  RIGHT  TO  REALIZE.  Subject to the provisions of Section 1.2,
upon  default  by  any  of  the  Obligors, as the case may be, under the Brascan
Security  or  the  Lender's  Security, as the case may be, the Lender or Brascan
shall  have the right to proceed against all, any or any portion of the Lender's
Security or the Brascan Security in such order and in such manner as it shall in
its  sole  discretion  deem  fit,  without waiving any right which the Lender or
Brascan  may  have with respect to any and all such securities, and the exercise
of  any  such  powers  or  remedies  from time to time shall in no way affect or
diminish  the  liability  of  any of the Obligors, as the case may be, under the
remaining  security.

                  ARTICLE SIX     - GENERAL CONTRACT PROVISIONS

6.1     NOTICES.  All  notices,  requests,  demands  or  other  communications
