                       No. S24042 (Previously S23703)
                       -----------------------------------------------
Dear Sirs,

               This transaction was affected through Scotia Capital (USA) Inc.,
a U.S. broker-dealer subsidiary of the Bank of Nova Scotia (BNS), who acted as
agent in the transaction.

               The purpose of this letter is to confirm the terms and conditions
of the transaction entered into between us on the Trade Date specified below
(the "Transaction"). This letter agreement constitutes a "Confirmation" as
referred to in the ISDA Agreement specified below.

               The definitions and provisions contained in the 1991 ISDA
Definitions (as amended and supplemented by the 1998 Supplement to the 1991 ISDA
Definitions) as published by the International Swaps and Derivatives
Association, Inc. ("ISDA") are incorporated into this Confirmation. This
Confirmation is subject to and incorporates the definitions contained in Section
14 of the form of the 1992 ISDA Master Agreement (Multicurrency - Cross Border),
but without any Schedule or other modification thereto, as published by ISDA
(the "ISDA Agreement"). In the event of any inconsistency between the
definitions contained in Section 14 of the ISDA Agreement and this Confirmation,
this Confirmation will govern. Until such time as an ISDA Agreement is entered
into between you and us, this Confirmation evidences a complete binding
agreement between you and us as to the terms of the Transaction to which this
Confirmation relates. Upon execution by you and us of an ISDA Agreement, with
such ISDA Agreement incorporating such modifications as you and we shall in good
faith agree, this Confirmation will supplement, form part of, and be subject to,
the ISDA Agreement. All provisions contained in the ISDA Agreement upon its
execution shall govern this Confirmation except as expressly modified below.

               1. Each party will make each payment specified in this
Confirmation as being payable by it, not later than the due date for value on
that date in the place specified below, in freely transferable funds and in the
manner customary for such payments in the required

                                       -2-
<Page>

currency. If on any date amounts would otherwise be payable in the same currency
by each party to the other, then, on such date, each party's obligation to make
payment of any such amount will be automatically satisfied and discharged and,
if the aggregate amount that would otherwise have been payable by one party
exceeds the aggregate amount that would otherwise have been payable by the other
party, replaced by an obligation upon the party by whom the larger aggregate
amount would have been payable to pay to the other party the excess of the
larger aggregate amount over the smaller aggregate amount.

               2. The following provisions will govern this Transaction until
such time as an ISDA Agreement is entered into between you and us whereupon such
provisions shall be replaced by the terms of the ISDA Agreement:

                    (a) If at any time, a party hereto shall (i) fail to make,
     when due, any payment required of it under this Confirmation and if such
     failure is not remedied within three Business Days following written notice
     of such failure; (ii) fail to deliver, when due, any Collateral (as defined
     below) required of it under this Confirmation; or (iii) becomes subject to
     a Bankruptcy (as defined in Section 5(a)(vii) of the ISDA Agreement) (such
     party being hereinafter referred to as the "Defaulting Party"), then the
     other party (hereinafter referred to as the "Non-defaulting Party"), shall
     have the right to early terminate and liquidate this Transaction, together
     with all other Specified Transaction entered into between Party A and Party
     B (collectively the "Terminated Transactions") and determine a net amount
     due in respect of the Terminated Transactions in accordance with the early
     termination payment calculation provisions of Section 6(e)(i) of the ISDA
     Agreement based on a payment measure of Loss and a payment method of Second
     Method. For purposes of giving effect to the foregoing, the Termination
     Currency shall be United States Dollars.

                    (b) The Non-defaulting Party may exercise its right to early
     termination and liquidate the Terminated Transactions by written notice to
     the Defaulting Party, which notice shall set forth the amount of the
     termination payment derived by the Non-defaulting Party as set forth above;
     provided that, in the event the Defaulting Party becomes subject to a
     Bankruptcy in the nature of any one of the events specified in Section
     5(a)(vii) (1), (3), (4), (5), (6) or, to the extent analogous thereto, (8),
     of the ISDA Agreement and any court, tribunal or regulatory authority with
     competent jurisdiction acting pursuant to any bankruptcy or insolvency law
     or other similar law affecting the Defaulting Party makes an order which
     has or purports to have the effect of prohibiting the Non-defaulting Party
     from terminating the Terminated Transactions at any time after the
     occurrence of any such events, then the Terminated Transactions shall be
     deemed to have been terminated immediately upon the occurrence of any of
     the events specified in Section 5(a)(vii) (1) (3), (5), (6) or, to the
     extent analogous thereto, (8) and as of the time immediately preceding the
     institution of the relevant proceeding or the presentation of the relevant
     petition in respect of Section 5(a)(vii) (4) or, to the extent analogous
     thereto, (8).

                    (c) In the event the termination payment derived in
     accordance with the foregoing represents an amount owing by the
     Non-defaulting Party to the Defaulting Party, the Non-defaulting Party
     shall have the right to set off such termination payment against any
     amounts payable (whether at such time or in the future or upon the

                                       -3-
<Page>

     occurrence of a contingency) by the Defaulting Party to the Non-defaulting
     Party (irrespective of the currency or the place of payment of the
     obligation) under any other agreement between the Defaulting Party and the
     Non-defaulting Party (the "Other Agreement Amount"). For this purpose, the
     termination payment of the Other Agreement Amount may be converted into the
     currency in which the other is denominated by the Non-defaulting Party
     acting in a commercially reasonable manner. If all or part of the Other
     Agreement Amount is not then due, such Other Agreement Amount, or part
     thereof, may be present-valued by the Non-defaulting Party acting in a
     commercially reasonable manner. If all or part of the Other Agreement
     Amount is unascertained, the Non-defaulting Party may in good faith
     estimate such amount and set off in respect of the estimate subject to
     accounting to the Defaulting Party when the obligation is ascertained.

               3. Each of the parties hereto makes to the other each of the
"Basic Representations" contained in Section 3(a) and (c) of the ISDA Agreement.

               4. Neither this Confirmation nor any interest or obligation in or
under this Confirmation may be transferred (whether by way of security or
otherwise) by either party without the prior written consent of the other party
and any purported transfer in violation hereof shall be void.

               5. The Confirmation will be governed and construed in accordance
with the laws of the State of New York.

               6. The terms of the particular Transaction to which this

Dear Sirs,

               This transaction was affected through Scotia Capital (USA) Inc.,
a U.S. broker-dealer subsidiary of the Bank of Nova Scotia (BNS), who acted as

               The purpose of this letter is to confirm the terms and conditions
of the transaction entered into between us on the Trade Date specified below
(the "Transaction"). This letter agreement constitutes a "Confirmation" as
referred to in the ISDA Agreement specified below.

definitions contained in Section 14 of the ISDA Agreement and this Confirmation,
this Confirmation will govern. Until such time as an ISDA Agreement is entered

the ISDA Agreement. All provisions contained in the ISDA Agreement upon its

               1. Each party will make each payment specified in this

               2. The following provisions will govern this Transaction until

provisions shall be replaced by the terms of the ISDA Agreement:

                    (a)  If at any time, a party hereto shall (i) fail to make,

     failure is not remedied within three Business Days following written notice
     of such failure; (ii) fail to deliver, when due, any Collateral (as defined
     below) required of it under this Confirmation; or (iii) becomes subject to
     a Bankruptcy (as defined in Section 5(a)(vii) of the ISDA Agreement) (such
     party being hereinafter referred to as the "Defaulting Party"), then the
     other party (hereinafter referred to as the "Non-defaulting Party"), shall

                    (b)  The Non-defaulting Party may exercise its right to
     early termination and liquidate the Terminated Transactions by written
     notice to the Defaulting Party, which notice shall set forth the amount of
     the termination payment derived by the Non-defaulting Party as set forth
     above; provided that, in the event the Defaulting Party becomes subject to
     a Bankruptcy in the nature of any one of the events specified in Section
     5(a)(vii) (1), (3), (4), (5), (6) or, to the extent analogous thereto, (8),
