     SECTION 2.01. Commitments to Lend. (a) Revolving Credit Loans. During its
Revolving Credit Period, each Bank severally agrees, on the terms and conditions
set forth in this Agreement, to make loans to the Borrower pursuant to this
subsection from time to time in amounts such that the aggregate principal amount
of Revolving Credit Loans by such Bank, together with its participating
interests in any Unrefunded Swingline Loans, at any one time outstanding shall
not exceed the amount of its Commitment. Each Borrowing under this subsection
(other than a Swingline Takeout Borrowing) shall be in an aggregate principal
amount of $10,000,000 or any larger multiple of $1,000,000 (except that any such
Borrowing may be in the aggregate amount available in accordance with Section
3.02(b)) and shall be made from the several Banks ratably in proportion to their
respective Commitments in effect on the date of Borrowing; provided that, if the
Interest Period selected by the Borrower for a Borrowing would otherwise end
after the Commitment Termination Dates of some but not all Banks, the Borrower
may in its Notice of Committed Borrowing elect not to borrow from those Banks
whose Commitment Termination Dates fall prior to the end of such Interest
Period. Within the foregoing limits, the Borrower may borrow under this
subsection (a), or to the extent permitted by Section 2.12, prepay Loans and

                                       12
<PAGE>

reborrow at any time during the Revolving Credit Periods under this subsection
(a).

     (b) Term Loans. Each Bank severally agrees, on the terms and conditions set
forth in this Agreement, to make a loan to the Borrower on its Commitment
Termination Date in an amount up to but not exceeding the amount of its
Commitment; provided that no Bank shall be obligated to make a loan pursuant to
this subsection if any Commitment is extended on such date pursuant to Section
2.01(d). Each Borrowing under this Section 2.01(1,) shall be made from the
several Banks having the same Commitment Termination Date ratably in proportion
to their respective Commitments.

     (c) Swingline Loans. From time to time prior to its Commitment Termination
Date, the Swingline Bank agrees, on the terms and conditions set forth in this
Agreement, to make loans to the Borrower pursuant to this subsection from time
to time in amounts such that (i) the aggregate principal amount of all Loans at
such time outstanding shall not exceed the aggregate amount of all Commitments
and (ii) the aggregate principal amount of Swingline Loans at any time
outstanding shall not exceed $100,000,000. Within the foregoing limits, the
Borrower may borrow under this subsection, repay or, to the extent permitted by
Section 2.12, prepay Loans and reborrow at any time; provided that the proceeds
of a Swingline Borrowing may not be used, in whole or in part, to refund any
prior Swingline Borrowing. Each Borrowing under this subsection shall be in an
aggregate principal amount of $10,000,000 or any larger multiple of $1,000,000
(except that any such Borrowing may be in the aggregate amount available in
accordance with Section 3.02).

     (d) Extension of Commitments. On no more than two separate occasions, the
Borrower may, upon not less than 45 days but no earlier than 60 days notice
prior to the then current Commitment Termination Dates to the Administrative
Agent (which shall notify each Bank of receipt of such request), propose to
extend the Commitment Termination Dates for an additional one-year period
measured from the Commitment Termination Dates then in effect. Each Bank shall
endeavor to respond to such request, whether affirmatively or negatively (such
determination in the sole discretion of such Bank), by notice to the Borrower
and the Administrative Agent not more than 45 days nor less than 28 days prior
to such Bank's Commitment Termination Date. Subject to the execution by the
Borrower, the Administrative Agent and such Banks of a duly completed Extension
Agreement in substantially the form of Exhibit H, the Commitment Termination
Date applicable to the Commitment of each Bank so affirmatively notifying the
Borrower and the Administrative Agent shall be extended for the period specified
above; provided that no Commitment Termination Date of any Bank shall be
extended unless Banks having

                                       13
<PAGE>

Commitments in an aggregate amount equal to at least 66 2/3% in aggregate
amount of the Commitments in effect at the time any such extension is requested
shall have elected so to extend their Commitments. Any Bank which does not give
such notice to the Borrower and the Administrative Agent shall be deemed to have
elected not to extend as requested, and the Commitment of each non-extending
Bank shall terminate on its Commitment Termination Date determined without
giving effect to such requested extension. The Borrower may, in accordance with
Section 8.06, designate another bank or other financial institution (which may
be, but need not be, an extending Bank) to replace a non-extending Bank.

     SECTION 2.02. Notice of Committed Borrowings. The Borrower shall give the

or Syndicated Loans,

such Borrowing are to bear interest initially at the Base Rate or a Euro-Dollar
Rate; and

     (e) in the case of a Euro-Dollar Borrowing or a Swingline Borrowing, the
duration of the initial Interest Period applicable thereto, subject to the
provisions of the definition of Interest Period.

Termination Dates to make offers to make Bid Rate Loans to the Borrower. The
Banks may, but shall have no obligation to, make such offers and the Borrower
may, but shall have no obligation to, accept any such offers in the manner set
forth in this Section.

Rate Quote submitted by a Bank that is in accordance with subsection (d) and (y)
of any Bid Rate Quote that amends, modifies or is otherwise inconsistent with a
previous Bid Rate Quote submitted by such Bank with respect to the same Bid Rate
Quote Request. Any such subsequent Quote shall be disregarded by the
Administrative Agent unless such subsequent Quote is submitted solely to correct
a manifest error in such former Quote. The Administrative Agent's notice to the

offers have been received for each Interest Period specified in the related Bid
Rate Quote Request, (B) the respective principal amounts and Bid Rate (Indexed)
Margins or Bid Rate

(General) Rates, as the case may be, so offered and (C) if applicable,

or date as the Borrower and the Administrative Agent shall have
mutually agreed and shall have notified to the Banks not later than
the date of the Bid Rate Quote Request for the first Bid Rate
(Indexed) Auction or Bid Rate (General) Auction for which such
change is to be effective), the Borrower shall notify the
Administrative Agent of its acceptance or non-acceptance of the
offers so notified to it pursuant to subsection (e). In the case of
acceptance, such notice (a "Notice of Bid Rate Borrowing") shall

in whole or in part; provided that:

                    (i) the aggregate principal amount of each Bid Rate

amount of Bid Rate Loans in respect of which such offers are accepted shall be
allocated by the Administrative Agent among such Banks as nearly as possible (in

Notice of Borrowing, the Administrative Agent shall promptly notify each Bank

                                       18
<PAGE>

of the contents thereof and of such Bank's share (if any) of such Borrowing and
such Notice of Borrowing shall not thereafter be revocable by the Borrower.

     (b) Not later than 1:00 P.M. (New York City time) on the date of each
Borrowing, each Bank participating therein shall (except as provided in
subsection (c) of this Section) make available its share of such Borrowing, in
Federal or other funds immediately available in New York City, to the
Administrative Agent at its address specified in or pursuant to Section 9.01.
Unless the Administrative Agent determines that any applicable condition
specified in Article 3 has not been satisfied, the Administrative Agent will
make the funds so received from the Banks available to the Borrower at the
Administrative Agent's aforesaid address.

     (c) Unless the Administrative Agent shall have received notice from a Bank
prior to the date of any Borrowing that such Bank will not make available to the
Administrative Agent such Bank's share of such Borrowing, the Administrative
Agent may assume that such Bank has made such share available to the
Administrative Agent on the date of such Borrowing in accordance with
subsections (b) of this Section 2.04 and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount. If and to the extent that such Bank shall not have so made
such share available to the Administrative Agent, such Bank and if such Bank
shall not have made such payment within two Domestic Business Days of demand
therefor, the Borrower severally agree to repay to the Administrative Agent
forthwith on demand such corresponding amount together with interest thereon,
for each day from the date such amount is made available to the Borrower until
the date such amount is repaid to the Administrative Agent, at (i) in the case
of the Borrower, a rate per annum equal to the higher of the Federal Funds Rate
and the interest rate applicable thereto pursuant to Section 2.07 and (ii) in
the case of such Bank, the Federal Funds Rate. If such Bank shall repay to the
Administrative Agent such corresponding amount, such amount so repaid shall
constitute such Bank's Loan included in such Borrowing for purposes of this
Agreement.

     (d) The failure of any Bank to make the Loan to be made by it as part of
any Borrowing shall not relieve any other Bank of its obligation, if any,
hereunder to make a Loan on the date of such Borrowing, but no Bank shall be
responsible for the failure of any other Bank to make a Loan to be made by such
other Bank.

     SECTION 2.05. Registry; Notes. (a) The Administrative Agent shall maintain
a register (the "Register") on which it will record the Commitment of each Bank,
each Loan made by such Bank and each repayment of any Loan made by such Bank.
Any such recordation by the Administrative Agent on the Register shall be
conclusive, absent manifest error. Failure to make any such recordation,

                                       19
<PAGE>

or any error in such recordation, shall not affect the Borrower's obligations
hereunder.

     (b) The Borrower hereby agrees that, promptly upon the request of any Bank
at any time, the Borrower shall deliver to such Bank a duly executed Note, in
substantially the form of Exhibit A hereto, payable to the order of such Bank
and representing the obligation of the Borrower to pay the unpaid principal
amount of the Loans made to the Borrower by such Bank, with interest as provided
herein on the unpaid principal amount from time to time outstanding.

     (c) Each Bank shall record the date, amount and maturity of each Loan made
by it and the date and amount of each payment of principal made by the Borrower
with respect thereto, and each Bank receiving a Note pursuant to this Section,
if such Bank so elects in connection with any transfer or enforcement of its
Note, may endorse on the schedule forming a part thereof appropriate notations
to evidence the foregoing information with respect to each such Loan then
outstanding; provided that the failure of such Bank to make any such recordation
or endorsement shall not affect the obligations of the Borrower hereunder or
under the Notes. Such Bank is hereby irrevocably authorized by the Borrower so
to endorse its Note and to attach to and make a part of its Note a continuation
of any such schedule as and when required.

     SECTION 2.06. Maturity of Loans. (a) Each Revolving Credit Loan made by any
Bank shall mature, and the principal amount thereof shall be due and payable
together with accrued interest thereon, on the Commitment Termination Date of
such Bank.

     (b) The Term Loans of each Bank shall mature, and the principal amount
thereof shall be due and payable, together with accrued interest thereon, on the
Final Maturity Date of such Bank.

     (c) Each Swingline Loan included in any Swingline Borrowing and each Bid
Rate Loan included in any Bid Rate Borrowing shall mature, and the principal
amount thereof shall be due and payable (together with interest accrued
thereon), on the last day of the Interest Period applicable to such Borrowing.

     SECTION 2.07. Interest Rates. (a) Each Base Rate Loan shall bear interest
on the outstanding principal amount thereof, for each day from the date such
Loan is made until it becomes due, at a rate per annum equal to the Base Rate
for such day. Such interest shall be payable quarterly in arrears on each
Quarterly Payment Date, at maturity and on the date of termination of the
Commitments in their entirety. Any overdue principal of or overdue interest on
any Base Rate Loan

                                       20
<PAGE>

shall bear interest, payable on demand, for each day until paid at a rate per
annum equal to the sum of 1% plus the Base Rate for such day.

     (b) Each Euro-Dollar Loan shall bear interest on the outstanding principal
amount thereof, for each day during each Interest Period applicable thereto, at
a rate per annum equal to the sum of the Euro-Dollar Margin for such day plus
the London Interbank Offered Rate applicable to such Interest Period. Such
interest shall be payable for each Interest Period on the last day thereof and,
if such Interest Period is longer than three months, at intervals of three
months after the first day thereof.

     The "London Interbank Offered Rate" applicable to any Interest Period means
the rate appearing on Page 3750 of the Telerate Service Company (or on any
successor or substitute page of such service, or any successor to or substitute
for such service, providing rate quotations comparable to those currently
provided on such page of the Telerate Service, as may be nominated by the
British Bankers' Association for purposes of providing quotations of interest
rates applicable to dollar deposits in the London interbank market) as of 11:00
A.M. (London time) two Euro-Dollar Business Days prior to the commencement of
such Interest Period, as the rate for dollar deposits with a maturity comparable
to such Interest Period. In the event that such rate is not so available at such
time for any reason, then the "London Interbank Offered Rate" for such Interest
Period shall be the average (rounded upward, if necessary, to the next higher
1/16 of 1%) of the respective rates per annum at which deposits in dollars are
offered to each of the Euro-Dollar Reference Banks in the London interbank
market at approximately 11:00 A.M. (London time) two Euro-Dollar Business Days
before the first day of such Interest Period in an amount approximately equal to
the principal amount of the Loan of such Euro-Dollar Reference Bank to which
such Interest Period is to apply and for a period of time comparable to such
Interest Period. If any Euro-Dollar Reference Bank does not furnish a timely
quotation, the Administrative Agent shall determine the relevant interest rate
on the basis of the quotation furnished by the remaining Euro-Dollar Reference
Bank or, if none of such quotations is available on a timely basis, the
provisions of Section 8.01 shall apply.

     (c) Any overdue principal of or overdue interest on any Euro-Dollar Loan
shall bear interest, payable on demand, for each day from and including the date
payment thereof was due to but excluding the date of actual payment, at a rate
per annum equal to the sum of 1% plus the higher of (i) the sum of the
Euro-Dollar Margin for such day plus the London Interbank Offered Rate
applicable to such Loan at the date such payment was due and (ii) the Base Rate
for such day.

                                       21
<PAGE>

     (d) Each Swingline Loan shall bear interest on the outstanding principal
amount thereof, for each day during the Interest Period applicable thereto, at a
rate per annum equal to the Base Rate for such day or such other rate as may be
from time to time determined by mutual agreement between the Swingline Bank and
the Borrower. Interest on each Swingline Loan shall be payable at the maturity
of such Loan. Any overdue principal of or interest on any Swingline Loan shall
bear interest, payable on demand, for each day until paid at a rate per annum
equal to the sum of 1% plus the Base Rate for such day.

     (e) Subject to Section 8.01(a), each Bid Rate (Indexed) Loan shall bear
interest on the outstanding principal amount thereof; for the Interest Period
applicable thereto, at a rate per annum equal to the sum of the London Interbank
Offered Rate for such Interest Period (determined in accordance with Section
2.07(b) as if each Euro-Dollar Reference Bank were to participate in the related
Bid Rate (Indexed) Borrowing ratably in proportion to its Commitment) plus (or
minus) the Bid Rate (Indexed) Margin quoted by the Bank making such Loan in
accordance with Section 2.03. Each Bid Rate (General) Loan shall bear interest
on the outstanding principal amount thereof, for the Interest Period applicable
thereto, at a rate per annum equal to the Bid Rate (General) quoted by the Bank
making such Loan in accordance with Section 2.03. Such interest shall be payable
for each Interest Period on the last day thereof and, if such Interest Period is
longer than three months, at intervals of three months after the first day
thereof. Any overdue principal of or overdue interest on any Bid Rate Loan shall
bear interest, payable on demand, for each day until paid at a rate per annum
equal to the sum of 1% plus the Base Rate for such day.

     (f) The Administrative Agent shall determine each interest rate applicable
to the Loans hereunder. The Administrative Agent shall give prompt notice to the
Borrower and the participating Banks by telecopy, telex or cable of each rate of
interest so determined, and its determination thereof shall be conclusive in the
absence of manifest error unless the Borrower raises an objection thereto within
five Domestic Business Days after receipt of such notice.

     SECTION 2.08. Fees. (a) Facility Fee. The Borrower shall pay to the
Administrative Agent for the account of each Bank a facility fee at the Facility
Fee Rate (determined daily in accordance with the Pricing Schedule). Such
facility fee shall accrue (i) from and including the Effective Date to but
excluding such Bank's Commitment Termination Date, on the daily average
aggregate amount of such Bank's Commitment (whether used or unused) and (ii)
from and including such Bank's Commitment Termination Date to but excluding the
date such Bank's Loans shall be repaid in their entirety, on the daily average
aggregate outstanding principal amount of such Bank's Committed Loans.

                                       22
<PAGE>

     (b) Payments. Accrued fees under this Section for the account of any Bank
shall be payable quarterly in arrears on each Quarterly Payment Date and upon
such Bank's Commitment Termination Date and Final Maturity Date (and, if later,
the date the Loans of such Bank shall be repaid in their entirety).

     SECTION 2.09. Optional Termination or Reduction of Commitments. The
Borrower may, upon at least three Domestic Business Days' notice to the
Administrative Agent, (i) terminate the Commitments at any time, if no Loans
are outstanding at such time, or (ii) ratably reduce from time to time by an
aggregate amount of $10,000,000 or any larger multiple of $1,000,000 the
aggregate amount of the Commitments in excess of the aggregate outstanding
principal amount of the Loans.

     SECTION 2.10. Method of Electing Interest Rates. (a) The Loans included in
each Syndicated Borrowing shall bear interest initially at the type of rate
specified by the Borrower in the applicable Notice of Committed Borrowing.
Thereafter, the Borrower may from time to time elect to change or continue the
type of interest rate borne by each Group of Loans (subject in each case to the
provisions of Article 8 and the last sentence of this subsection (a)), as
follows:

                    (i) if such Loans are Base Rate Loans, the Borrower may
          elect to convert such Loans to Euro-Dollar Loans as of any Euro-Dollar
          Business Day; and

                    (ii) if such Loans are Euro-Dollar Loans, the Borrower may
          elect to convert such Loans to Base Rate Loans or elect to continue
          such Loans as Euro-Dollar Loans for an additional Interest Period,
          subject to Section 2.14 in the case of any such conversion or
          continuation effective on any day other than the last day of the then
          current Interest Period applicable to such Loans.

Each such election shall be made by delivering a notice (a "Notice of Interest
Rate Election") to the Administrative Agent not later than 11:00 A.M. New York
City time) on the third Euro-Dollar Business Day before the conversion or
continuation selected in such notice is to be effective. A Notice of Interest
Rate Election may, if it so specifies, apply to only a portion of the aggregate
principal amount of the relevant Group of Loans, provided that (i) such portion
is allocated ratably among the Loans comprising such Group and (ii) the portion
to which such notice applies, and the remaining portion to which it does not
apply, are each $10,000,000 or any larger multiple of $1,000,000.

     (b) Each Notice of Interest Rate Election shall specify:

                                       23
<PAGE>

                    (i) the Group of Loans (or portion thereof) to which such
          notice applies;

                    (ii) the date on which the conversion or continuation
          selected in such notice is to be effective, which shall comply with
          the applicable clause of subsection 2.10(a) above;

                    (iii) if the Loans comprising such Group are to be
          converted, the new type of Loans and, if the Loans being converted are
          to be Fixed Rate Loans, the duration of the next succeeding Interest
          Period applicable thereto; and

                    (iv) if such Loans are to be continued as Euro-Dollar Loans
          for an additional Interest Period, the duration of such additional
          Interest Period.

Each Interest Period specified in a Notice of Interest Rate Election shall
comply with the provisions of the definition of the term "Interest Period".

     (c) Promptly after receiving a Notice of Interest Rate Election from the
Borrower pursuant to subsection 2.10(a) above, the Administrative Agent shall
notify each Bank of the contents thereof and such notice shall not thereafter be
revocable by the Borrower. If no Notice of Interest Rate Election is timely
received prior to the end of an Interest Period for any Group of Loans, the
Borrower shall be deemed to have elected that such Group of Loans be converted
to Base Rate Loans as of the last day of such Interest Period.

     (d) An election by the Borrower to change or continue the rate of interest
applicable to any Group of Loans pursuant to this Section shall not constitute a
"Borrowing" subject to the provisions of Section 3.02.

     SECTION 2.11. Mandatory Termination of Commitments. The Commitment of each
Bank shall terminate on such Bank's Commitment Termination Date, and any
Revolving Credit Loans of such Bank then outstanding (together with accrued
interest thereon) shall be due and payable on such date.

     SECTION 2.12. Optional Prepayments. (a) The Borrower may (i) upon notice to
the Administrative Agent not later than 11:00 A.M. (New York City time) on any
Domestic Business Day prepay on such Domestic Business Day any Group of Base
Rate Loans, any Swingline Borrowing or any Bid Rate Borrowing bearing interest
at the Base Rate pursuant to Section 8.01(a) and (ii) upon at least three
Euro-Dollar Business Days' notice to the Administrative Agent not later than
11:00 A.M. (New York City time) prepay any Group of Euro-Dollar Loans, in each
case in whole at any time, or from time to time in part in amounts

                                       24
<PAGE>

aggregating $5,000,000 or any larger multiple of $1,000,000, by paying the
principal amount to be prepaid together with accrued interest thereon to the
date of prepayment and together with any additional amounts payable pursuant to
Section 2.14. Each such optional prepayment shall be applied to prepay ratably
the Loans of the several Banks included in such Group or Borrowing.

     (b) Except as provided in subsection 2.12(a), the Borrower may not prepay
all or any portion of the principal amount of any Bid Rate Loan prior to the
maturity thereof except with the express written consent of the Bank holding
such Bid Rate Loan.

     (c) Upon receipt of a notice of prepayment pursuant to this Section, the
Administrative Agent shall promptly notify each Bank of the contents thereof and
of such Bank's share (if any) of such prepayment and such notice shall not
thereafter be revocable by the Borrower.

     SECTION 2.13. General Provisions as to Payments. (a) The Borrower shall
make each payment of principal of, and interest on, the Loans and of fees
hereunder, not later than 1:00 P.M. (New York City time) on the date when due,
in Federal or other funds immediately available in New York City, to the
Administrative Agent at its address referred to in Section 9.01. The
Administrative Agent will promptly distribute to each Bank in like funds its
ratable share of each such payment received by the Administrative Agent for the
account of the Banks. Whenever any payment of principal of, or interest on, the
Base Rate Loans or Swingline Loans or of fees shall be due on a day which is not
a Domestic Business Day, the date for payment thereof shall be extended to the
next succeeding Domestic Business Day. Whenever any payment of principal of, or
interest on, the Euro-Dollar Loans shall be due on a day which is not a
Euro-Dollar Business Day, the date for payment thereof shall be extended to the
next succeeding Euro-Dollar Business Day unless such Euro-Dollar Business Day
falls in another calendar month, in which case the date for payment thereof
shall be the next preceding Euro-Dollar Business Day. Whenever any payment of
principal of or interest on, the Bid Rate Loans shall be due on a day which is
not a Euro-Dollar Business Day, the date for payment thereof shall be extended
to the next succeeding Euro-Dollar Business Day. If the date for any payment of
principal is extended by operation of law or otherwise, interest thereon shall
be payable for such extended time.

     (b) Unless the Administrative Agent shall have received notice from the
Borrower prior to the date on which any payment is due to the Banks hereunder
that the Borrower will not make such payment in full, the Administrative Agent
may assume that the Borrower has made such payment in full to the
Administrative Agent on such date and the Administrative Agent may, in reliance

                                       25
<PAGE>

upon such assumption, cause to be distributed to each Bank on such due date an
amount equal to the amount then due such Bank. If and to the extent that the
Borrower shall not have so made such payment, each Bank shall repay to the
Administrative Agent forthwith on demand such amount distributed to such Bank
together with interest thereon, for each day from the date such amount is
distributed to such Bank until the date such Bank repays such amount to the
Administrative Agent, at the Federal Funds Rate.

     SECTION 2.14. Funding Losses. If the Borrower makes any payment of
principal with respect to any Fixed Rate Loan or any Euro-Dollar Loan is
converted to a Base Rate Loan or continued as a Euro-Dollar Loan for a new
Interest Period (pursuant to Article 2, 6 or 8 or otherwise) on any day other
than the last day of an Interest Period applicable thereto, or if the Borrower
fails to borrow, prepay, convert or continue any Fixed Rate Loans after notice
has been given to any Bank in accordance with Section 2.04(a), 2.10(c) or
2.l2(c), the Borrower shall reimburse each Bank within 15 days after demand for
any resulting loss or expense incurred by it (or by an existing or prospective
Participant in the related Loan), including (without limitation) any loss
incurred in obtaining, liquidating or employing deposits from third parties, but
excluding loss of margin for the period after any such payment or conversion or
failure to borrow, prepay, convert or continue, provided that such Bank shall
have delivered to the Borrower a certificate setting forth in reasonable detail
the calculation of the amount of such loss or expense, which certificate shall
he conclusive in the absence of manifest error.

     SECTION 2.15. Computation of Interest and Fees. Interest based on the Prime
Rate and facility fees hereunder shall be computed on the basis of a year of 365
days (or 366 days in a leap year) and paid for the actual number of days elapsed
(including the first day but excluding the last day). All other interest shall
be computed on the basis of a year of 360 days and paid for the actual number of
days elapsed (including the first day but excluding the last day).

     SECTION 2.16. Regulation D Compensation. In the event that a Bank is
required to maintain reserves of the type contemplated by the definition of
"Euro-Dollar Reserve Percentage", such Bank may require the Borrower to pay,
contemporaneously with each payment of interest on the Euro-Dollar Loans,
additional interest on the related Euro-Dollar Loan of such Bank at a rate per
annum determined by such Bank up to but not exceeding the excess of (i) (A) the
applicable London Interbank Offered Rate divided by (B) one minus the
Euro-Dollar Reserve Percentage over (ii) the applicable London Interbank Offered
Rate. Any Bank wishing to require payment of such additional interest (x) shall
so notify the Borrower and the Administrative Agent, in which case such
additional interest on the Euro-Dollar Loans of such Bank shall be payable to
such Bank at

                                       26
<PAGE>

the place indicated in such notice with respect to each Interest Period
commencing at least three Euro-Dollar Business Days after the giving of such
notice and (y) shall notify the Borrower at least three Euro-Dollar Business
Days prior to each date on which interest is payable on the Euro-Dollar Loans of
the amount then due it under this Section. Each such notification shall be
accompanied by such information as the Borrower may reasonably request.

     "Euro-Dollar Reserve Percentage" means for any day that percentage
(expressed as a decimal) which is in effect on such day, as prescribed by the
Board of Governors of the Federal Reserve System (or any successor) for
determining the maximum reserve requirement for a member bank of the Federal
Reserve System in New York City with deposits exceeding five billion dollars in
respect of "Eurocurrency liabilities" (or in respect of any other category of
liabilities which includes deposits by reference to which the interest rate on
Euro-Dollar Loans is determined or any category of extensions of credit or other
assets which includes loans by a non-United States office of any Bank to United
States residents).

     SECTION 2.17. Takeout of Swingline Loans. (a) In the event that any
Swingline Borrowing shall not be repaid in full at or prior to the maturity
thereof the Administrative Agent shall, on behalf of the Borrower (the Borrower
hereby irrevocably directing and authorizing the Administrative Agent so to act
on its behalf), give a Notice of Borrowing requesting the Banks, including the
Swingline Bank, to make Base Rate Loans on the maturity date of such Swingline
Borrowing in an aggregate amount equal to the unpaid principal amount of such
Swingline Borrowing. Each Bank will make the proceeds of such Base Rate Loans
available to the Administrative Agent for the account of the Swingline Bank on
such date in accordance with Section 2.04. The proceeds of such Base Rate
Borrowing shall be immediately applied to repay such Swingline Borrowing.

     (b) If, for any reason, a Base Rate Borrowing may not be (as determined by
the Administrative Agent in its sole discretion), or is not, made pursuant to
subsection (a) above to refund Swingline Loans as required by said clause,
then, effective on the date such Borrowing would otherwise have been made, each
Bank severally, unconditionally and irrevocably agrees that it shall purchase an
undivided participating interest in such Swingline Loans ("Unrefunded Swingline
Loans") in an amount equal to the amount of the Loan which otherwise would have
been made by such Bank pursuant to subsection (a), which purchase shall be
funded by the time such Loan would have been required to be funded pursuant to
Section 2.04 by transfer to the Administrative Agent, for the account of the
Swingline Bank, in immediately available funds, of the amount of its
participation.

                                       27
<PAGE>

     (c) Whenever, at any time after the Swingline Bank has received from any
Bank payment in full for such Bank's participating interest in a Swingline
Loan, the Swingline Bank (or the Administrative Agent on its behalf) receives
any payment on account thereof; the Swingline Bank (or the Administrative Agent,
as the case may be) will promptly distribute to such Bank its participating
interest in such payment (appropriately adjusted, in the case of interest
payments, to reflect the period of time during which such Bank's participating
interest was outstanding and funded); provided, however, that in the event that
such payment is subsequently required to be returned, such Bank will return to
the Swingline Bank (or the Administrative Agent, as the case may be) any portion
thereof previously distributed by the Swingline Bank (or the Administrative
Agent, as the case may be) to it.

     (d) Each Bank's obligation to purchase and fund participating interests
pursuant to this Section shall be absolute and unconditional and shall not be
affected by any circumstance, including, without limitation: (i) any setoff;
counterclaim, recoupment, defense or other right which such Bank or the Borrower
may have against the Swingline Bank, or any other Person for any reason
whatsoever; (ii) the occurrence or continuance of a Default or the failure to
satisfy any of the conditions specified in Article 3; (iii) any adverse change
in the condition (financial or otherwise) of the Borrower; (iv) any breach of
this Agreement by the Borrower or any Bank; or (v) any other circumstance,
happening or event whatsoever, whether or not similar to any of the foregoing.

party hereto unless all of the foregoing conditions are satisfied not later than
August 29, 2001. The Administrative Agent shall promptly notify the Borrower and
the Banks of the Effective Date, and such notice shall be conclusive and binding
on all parties hereto. The Borrower and the Banks party to the Existing Credit
Agreement, comprising the "Required Banks" as defined therein, hereby agree that
(i) the commitments of the lenders under the Existing Credit Agreement shall
terminate in their entirety immediately and automatically upon the effectiveness
of this Agreement, without further action by any party to the Existing Credit
Agreement, (ii) all accrued fees under the Existing Credit Agreement shall be
due and payable at such time and (iii) subject to the funding loss indemnities

     SECTION 3.02. Borrowings. The obligation of any Bank to make a Loan on the

     SECTION 7.03. Action by Administrative Agent. The obligations of the
Administrative Agent hereunder are only those expressly set forth herein.
Without limiting the generality of the foregoing, the Administrative Agent shall
not be required to take any action with respect to any Default, except as
expressly provided in Article 6.

     SECTION 7.04. Consultation with Experts. The Administrative Agent may
consult with legal counsel (who may be counsel for the Borrower), independent
public accountants and other experts selected by it and shall not be liable for
any

                                       41
<PAGE>

action taken or omitted to be taken by it in good faith in accordance with the
advice of such Counsel, accountants or experts.

     SECTION 7.05. Liability of Administrative Agent. Neither the Administrative
Agent nor any of its affiliates nor any of their respective directors, officers,
agents or employees shall be liable to any Bank for any action taken or not
taken by it in connection herewith (i) with the consent or at the request of the
Required Banks or (ii) in the absence of its own gross negligence or willful
misconduct. Neither the Administrative Agent nor any of its affiliates nor any
of their respective directors, officers, agents or employees shall be
responsible for or have any duty to ascertain, inquire into or verify (i) any
statement, warranty or representation made in connection with this Agreement or
any borrowing hereunder; (ii) the performance or observance of any of the
covenants or agreements of the Borrower; (iii) the satisfaction of any condition
specified in Article 3, except receipt of items required to be delivered to the
Administrative Agent; or (iv) the validity, effectiveness or genuineness of this
Agreement, the Notes or any other instrument or writing furnished in connection
herewith. The Administrative Agent shall not incur any liability by acting in
reliance upon any notice, consent, certificate, statement, or other writing
(which may be a bank wire, telex or similar writing) believed by it in good
faith to be genuine or to be signed by the proper Party or parties. Without
limiting the generality of the foregoing, the use of the term "agent" in this
Agreement with reference to the Administrative Agent is not intended to connote
any fiduciary or other implied (or express) obligations arising under agency
doctrine of any applicable law. Instead, such term is used merely as a matter of
market custom and is intended to create or reflect only an administrative
relationship between independent contracting parties.

     SECTION 7.06. Indemnification. Each Bank shall, ratably in accordance with
its Commitment, indemnify the Administrative Agent, its affiliates and their
respective directors, officers, agents and employees (to the extent not
reimbursed by the Borrower) against any cost, expense (including counsel fees
and disbursements), claim, demand, action, loss or liability (except such as
result from such indemnitees'' gross negligence or willful misconduct) that such
indemnitees may suffer or incur in connection with this Agreement or any action
taken or omitted by such indemnitees thereunder.

     SECTION 7.07. Credit Decision. Each Bank acknowledges that it has,
independently and without reliance upon the Administrative Agent or any other
Bank, and based on such documents and information as it has deemed appropriate,
made its own credit analysis and decision to enter into this Agreement. Each
Bank also acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Bank, and based on such documents and

                                       42
<PAGE>

information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking any action under this Agreement.

     SECTION 7.08. Successor Administrative Agent. The Administrative Agent may
resign at any time by giving notice thereof to the Banks and the Borrower. Upon
any such resignation, the Borrower, with the consent of the Required Banks (such
consent not to be unreasonably withheld or delayed), shall have the right to
appoint a successor Administrative Agent. If no successor Administrative Agent
shall have been so appointed, and shall have accepted such appointment, within
30 days after the retiring Administrative Agent gives notice of resignation,
then the retiring Administrative Agent may, on behalf of the Banks, appoint a
successor Administrative Agent, which shall be a commercial bank organized or
licensed under the laws of the United States of America or of any State thereof
and having a combined capital and surplus of at least $250,000,000. Upon the
acceptance of its appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged
from its duties and obligations hereunder; provided that if such successor
Administrative Agent is appointed without the consent of the Borrower, such
successor Administrative Agent may be replaced by the Borrower with the consent
of the Required Banks. After any retiring Administrative Agent's resignation
hereunder as Administrative Agent, the provisions of this Article shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent.

     SECTION 7.09. Administrative Agent's Fee. The Borrower shall pay to the
Administrative Agent for its own account fees in the amounts and at the times
previously agreed upon between the Borrower and the Administrative Agent.

     SECTION 7.10. Documentation Agents. None of the Documentation Agents, in
their capacity as such, shall have any duties or obligations of any kind under
this Agreement.

                                    ARTICLE 8
                             CHANGE IN CIRCUMSTANCES

     SECTION 8.01. Basis for Determining Interest Rate Inadequate or Unfair. If
on or prior to the first day of any Interest Period for any Euro-Dollar
Borrowing or Bid Rate (Indexed) Borrowing.

                                       43
<PAGE>

     (a) the Administrative Agent is advised by the Euro-Dollar Reference Banks
that deposits in dollars (in the applicable amounts) are not being offered to
the Euro-Dollar Reference Banks in the relevant market for such Interest Period,
or

     (b) in the case of a Euro-Dollar Borrowing, Banks having 66-2/3% or more of
the aggregate amount of the affected Loans advise the Administrative Agent that
the London Interbank Offered Rate as determined by the Administrative Agent will
not adequately and fairly reflect the cost to such Banks of funding their Euro-
Dollar Loans for such Interest Period, the Administrative Agent shall forthwith
give notice thereof to the Borrower and the Banks, whereupon until the
Administrative Agent notifies the Borrower that the circumstances giving rise to
such suspension no longer exist, (i) the obligations of the Banks to make Euro-
Dollar Loans or to continue or convert outstanding Loans as or into Euro-Dollar
Loans shall be suspended and (ii) each outstanding Euro-Dollar Loan shall be
converted into a Base Rate Loan on the last day of the then current Interest
Period applicable thereto. Unless the Borrower notifies the Administrative Agent
at least one Domestic Business Day before the date of any Fixed Rate Borrowing
for which a Notice of Borrowing has previously been given that it elects not to
borrow on such date, (i) if such Fixed Rate Borrowing is a Syndicated Borrowing,
such Borrowing shall instead be made as a Base Rate Borrowing and (ii) if such
Borrowing is a Bid Rate (Indexed) Borrowing, the Loans comprising such Borrowing
shall bear interest for each day from and including the first day to but
excluding the last day of the Interest Period applicable thereto at the Base
Rate for such day.

     SECTION 8.02. Illegality. If, on or after the date of this Agreement, the
adoption of any applicable law, rule or regulation, or any change in any
applicable law, rule or regulation, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any Bank (or its Euro-Dollar Lending Office) with any request or directive
(whether or not having the force of law) of any such authority, central bank or
comparable agency shall make it unlawful or impossible for any Bank (or its
Euro-Dollar Lending Office) to make, maintain or Fund any of its Euro-Dollar
Loans and such Bank shall so notify the Administrative Agent, the Administrative
Agent shall forthwith give notice thereof to the other Banks and the Borrower,
whereupon until such Bank notifies the Borrower and the Administrative Agent
that the circumstances giving rise to such suspension no longer exist, the
obligation of such Bank to make Euro-Dollar Loans, or to continue or convert
outstanding Loans as or into Euro-Dollar Loans, shall be suspended. Before
giving any notice to the Administrative Agent pursuant to this Section, such
Bank shall designate a

                                       44
<PAGE>

different Euro-Dollar Lending Office if such designation will avoid the need for
giving such notice and will not be otherwise disadvantageous to such Bank in the
good faith exercise of its discretion. if such notice is given, each Euro-Dollar
Loan of such Bank then outstanding shall be converted to a Base Rate Loan either
(a) on the last day of the then current Interest Period applicable to such
Euro-Dollar Loan if such Bank may lawfully continue to maintain and fund such
Loan to such day or (b) immediately if such Bank shall determine that it may not
lawfully continue to maintain and fund such Loan to such day.

     SECTION 8.03. Increased Cost and Reduced Return. (a) if on or after (x) the
date of this Agreement, in the case of any Committed Loan or any obligation to
make Committed Loans or (y) the date of any related Bid Rate Quote, in the case
of any Bid Rate Loan, the adoption of any applicable law, rule or regulation, or
any change in any applicable law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof; or compliance by any Bank (or its Applicable Lending Office) with any
request or directive (whether or not having the force of law) issued on or after
such date of any such authority, central bank or comparable agency shall impose,
modify or deem applicable any reserve, special deposit or similar requirement
(including, without limitation, any such requirement imposed by the Board of
Governors of the Federal Reserve System, but excluding with respect to any
Euro-Dollar Loan any such requirement included in an applicable Euro-Dollar
Reserve Percentage) against assets of deposits with or for the account of or
credit extended by, any Bank (or its Applicable Lending Office) or shall impose
on any Bank (or its Applicable Lending Office) or on the London interbank market
any other condition (other than in respect of Taxes or Other Taxes) affecting
its Fixed Rate Loans, its Note or its obligation to make Fixed Rate Loans and
the result of any of the foregoing is to increase the cost to such Bank (or its
Applicable Lending Office) of making or maintaining any Fixed Rate Loan, or to
reduce the amount of any sum received or receivable by such Bank (or its
Applicable Lending Office) under this Agreement or under its Note with respect
thereto, by an amount deemed by such Bank to be material, then, within 15 days
after demand by such Bank (with a copy to the Administrative Agent), the
Borrower shall pay to such Bank such additional amount or amounts as will
compensate such Bank for such increased cost or reduction; provided that no such
amount shall be payable with respect to any period commencing more than 90 days
prior to the date such Bank first notifies the Borrower of its intention to
demand compensation therefor under this Section 8.03(a).

     (b) If any Bank shall have determined that, on or after the date of this
Agreement, the adoption of any applicable law, rule or regulation regarding
capital adequacy, or any change in any such law, rule or regulation, or any
change

                                       45
<PAGE>

in the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency given or made after the date of this Agreement, has or would
have the effect of reducing the rate of return on capital of such Bank (or its
Parent) as a consequence of such Bank's obligations hereunder to a level below
that which such Bank (or its Parent) could have achieved but for such adoption,
change, request or directive (taking into consideration its policies with
respect to capital adequacy) by an amount deemed by such Bank to be material,
then from time to time, within 15 days after demand by such Bank (with a copy
to the Administrative Agent), the Borrower shall pay to such Bank such
additional amount or amounts as will compensate such Bank (or its Parent) for
such reduction; provided that no such amount shall be payable with respect to
any period commencing less than 30 days after the date such Bank first notifies
the Borrower of its intention to demand compensation under this Section 8.03(b).

     (c) Each Bank will promptly notify the Borrower and the Administrative
Agent of any event of which it has knowledge, occurring after the date hereof,
which will entitle such Bank to compensation pursuant to this Section and will
designate a different Applicable Lending Office if such designation will avoid
the need for, or reduce the amount of, such compensation and will not, in the
judgment of such Bank, be otherwise disadvantageous to such Bank. A certificate
of any Bank claiming compensation under this Section and setting forth the
additional amount or amounts to be paid to it hereunder shall be conclusive in
the absence of manifest error. In determining such amount, such Bank may use any
reasonable averaging and attribution methods.

     SECTION 8.04. Taxes. (a) For purposes of this Section 8.04, the following
terms have the following meanings:

     "Taxes" means any and all present or future taxes, duties, levies, imposts,
deductions, charges or withholdings with respect to any payment by the Borrower
pursuant to this Agreement or any Note, and all liabilities with respect
thereto, excluding (i) in the case of each Bank and the Administrative Agent,
taxes imposed on its income, net worth or gross receipts and franchise or
similar taxes imposed on it by a jurisdiction under the laws of which such Bank
or the Administrative Agent (as the case may be) is organized or in which its
principal executive office is located or, in the case of each Bank, in which its
Applicable Lending Office is located and (ii) in the case of each Bank, any
United States withholding tax imposed on such payments except to the extent that
such Bank is subject to United States withholding tax by reason of a U.S. Tax
Law Change.

                                       46
<PAGE>

     "Other Taxes" means any present or fixture stamp or documentary taxes and
any other excise or property taxes, or similar charges or levies, which arise
from any payment made pursuant to this Agreement or under any Note or from the
execution or delivery of, or otherwise with respect to, this Agreement or any
Note.

     "U.S. Tax Law Change" means with respect to any Bank or Participant the
occurrence (x) in the case of each Bank listed on the signature pages hereof,
after the date of its execution and delivery of this Agreement and (y) in the
case of any other Bank, after the date such Bank shall have become a Bank
hereunder, and (z) in the case of each Participant, after the date such
Participant became a Participant hereunder, of the adoption of any applicable
U.S. federal law, U.S. federal rule or U.S. federal regulation relating to
taxation, or any change therein, or the entry into force, modification or
revocation of any income tax convention or treaty to which the United States is
a party.

     (b) Any and all payments by the Borrower to or for the account of any Bank
or the Administrative Agent hereunder or under any Note shall be made without
deduction for any Taxes or Other Taxes; provided that, if the Borrower shall be
required by law to deduct any Taxes or Other Taxes from any such payments, (i)
the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 8.04) such Bank or the Administrative Agent (as the case may
be) receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions, (iii) the
Borrower shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law and (iv) the Borrower shall
furnish to the Administrative Agent, at its address referred to in Section
9.01, the original or a certified copy of a receipt evidencing payment thereof

     (c) The Borrower agrees to indemnify each Bank and the Administrative Agent
for the full amount of Taxes or Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable
under this Section 8.04) paid by such Bank or the Administrative Agent (as the
ease may be) and any liability (including penalties, interest and expenses)
arising therefrom or with respect thereto. This indemnification shall be paid
within 15 days after such Bank or the Administrative Agent (as the case may be)
makes demand therefor.

     (d) Each Bank organized under the laws of a jurisdiction outside the United
States, on or prior to the date of its execution and delivery of this Agreement
in the case of each Bank listed on the signature pages hereof and on or prior to
the date on which it becomes a Bank in the case of each other Bank, and from
time to time thereafter as required by law (but only so long as such Bank

                                       47
<PAGE>

remains lawfully able to do so), shall provide the Borrower two completed and
duly executed copies of Internal Revenue Service form W-8BEN or W-8ECI, as
appropriate, or any successor form prescribed by the Internal Revenue Service,
or other documentation reasonably requested by the Borrower, certifying that
such Bank is entitled to benefits under an income tax treaty to which the United
States is a party which exempts the Bank from United States withholding tax or
reduces the rate of withholding tax on payments of interest for the account of
such Bank or certifying that the income receivable pursuant to this Agreement is
effectively connected with the conduct of a trade or business in the United
States.

     (e) For any period with respect to which a Bank has failed to provide the
Borrower with the appropriate form pursuant to Section 8.04(d) (unless such
failure is due to a U.S. Tax Law Change), such Bank shall not be entitled to
indemnification under Section 8.04(b) or 8.04(c) with respect to any Taxes or
Other Taxes which would not have been payable had such form been so provided,
provided that if a Bank, which is otherwise exempt from or subject to a reduced
rate of withholding tax, becomes subject to Taxes because of its failure to
deliver a form required hereunder, the Borrower shall take such steps as such
Bank shall reasonably request to assist such Bank to recover such Taxes (it
being understood, however, that the Borrower shall have no liability to such
Bank in respect of such Taxes).

     (f) if the Borrower is required to pay additional amounts to or for the
account of any Bank pursuant to this Section 8.04, then such Bank will take such
action (including changing the jurisdiction of its Applicable Lending Office) as
in the good faith judgment of such Bank (i) will eliminate or reduce any such
additional payment which may thereafter accrue and (ii) is not otherwise
disadvantageous to such Bank.

     (g) if any Bank or the Administrative Agent receives a refund (including a
refund in the form of a credit against taxes that are otherwise payable by the
Bank or the Administrative Agent) of any Taxes or Other Taxes for which the
Borrower has made a payment under Section 8.04(b) or (c) and such refund was
received from the taxing authority which originally imposed such Taxes or Other
Taxes, such Bank or the Administrative Agent agrees to reimburse the Borrower to
the extent of such refund, provided that nothing contained in this paragraph (g)
shall require any Bank or the Administrative Agent to seek any such refund or
make available its tax returns (or any other information relating to its taxes
which it deems to be confidential).

     SECTION 8.05. Base Rate Loans Substituted for Affected Fixed Rate Loans. If
(i) the obligation of any Bank to make or to continue or convert outstanding
Loans as or into Euro-Dollar Loans has been suspended pursuant to

                                       48
<PAGE>

Section 8.02 or (ii) any Bank has demanded compensation under Section 8.03(a) or
8.04 with respect to its Euro-Dollar Loans and the Borrower shall, by at least
five Euro-Dollar Business Days' prior notice to such Bank through the
Administrative Agent, have elected that the provisions of this Section shall
apply to such Bank, then, unless and until such Bank notifies the Borrower that
the circumstances giving rise to such suspension or demand for compensation no
longer apply:

     (a) all Loans which would otherwise be made by such Bank as (or continued
as or converted to) Euro-Dollar Loans, as the case may be, shall instead be Base
Rate Loans (on which interest and principal shall be payable contemporaneously
with the related Euro-Dollar Loans of the other Banks), and

     (b) after each of its Euro-Dollar Loans has been repaid, all payments of
principal which would otherwise be applied to repay such Loans shall be applied
to repay its Base Rate Loans instead.

If such Bank notifies the Borrower that the circumstances giving rise to such
suspension or demand for compensation no longer exist, the principal amount of
each such Base Rate Loan shall be converted into a Euro-Dollar Loan on the first
day of the next succeeding Interest Period applicable to the related Euro-Dollar
Loans of the other Banks.

     SECTION 8.06. Substitution of Rank; Termination Option. If (i) the
obligation of any Bank to make or to convert or continue outstanding Loans as or
into Euro-Dollar Loans has been suspended pursuant to Section 8.02, (ii) any
Bank has demanded compensation under Section 8.03 or 8.04, (iii) any Bank
exercises its right not to extend its Commitment Termination Date pursuant to
Section 2.01(d) or (iv) Investment Grade Status ceases to exist as to any Bank,
then:

     (a) the Borrower shall have the right, with the assistance of the
Administrative Agent, to designate a substitute bank or banks (which may be one
or more of the Banks) mutually satisfactory to the Borrower, the Administrative
Agent and the Swingline Bank (whose consent shall not be unreasonably withheld
or delayed) to purchase for cash, pursuant to an Assignment and Assumption
Agreement in substantially the form of Exhibit G hereto, the outstanding Loans
of such Bank and assume the Commitment of such Bank, without recourse to or
warranty by, or expense to, such Bank, for a purchase price equal to the
principal amount of all of such Bank's outstanding Loans plus any accrued but
unpaid interest thereon and the accrued but unpaid fees in respect of such
Bank's Commitment hereunder and all other amounts payable by the Borrower to
such Bank hereunder plus such amount, if any, as would be payable pursuant to
Section

                                       49
<PAGE>

2.14 if the outstanding Loans of such Bank were prepaid in their entirety on the
date of consummation of such assignment; and

     (b) if at the time Investment Grade Status exists as to the Borrower, the
Borrower may elect to terminate this Agreement as to such Bank, provided that
(i) the Borrower notifies such Bank through the Administrative Agent of such
election at least three Euro-Dollar Business Days before the effective date of
such termination, (ii) the Borrower repays or prepays the principal amount of
all outstanding Loans made by such Bank plus any accrued but unpaid interest
thereon and the accrued but unpaid fees in respect of such Bank's Commitment
hereunder plus all other amounts payable by the Borrower to such Bank hereunder,
not later than the effective date of such termination and (iii) if at the
effective date of such termination, any Swingline Loans are outstanding, the
conditions specified in Section 3.02 would be satisfied (after giving effect to
such termination) were the related Swingline Loans made on such date. Upon
satisfaction of the foregoing conditions, the Commitment of such Bank shall
terminate on the effective date specified in such notice.

                                    ARTICLE 9
                                  MISCELLANEOUS

     SECTION 9.01. Notices. All notices, requests and other communications to
any party hereunder shall be in writing (including bank wire, telex, facsimile
transmission or similar writing) and shall be given to such party: (x) in the
case of the Borrower or the Administrative Agent, at its address or telecopy or
telex number set forth on the signature pages hereof, (y) in the case of any
Bank, at its address or telecopy or telex number set forth in its Administrative
Questionnaire or (z) in the case of any party, such other address or telecopy or
telex number as such party may hereafter specify for the purpose by notice to
the Administrative Agent and the Borrower. Each such notice, request or other
communication shall be effective (i) if given by telecopy or telex, when such
telecopy or telex is transmitted to the telecopy or telex number specified in
this Section and the appropriate answerback or confirmation slip, as the case
may be, is received or (ii) if given by any other means, when delivered at the
address specified in this Section; provided that notices to the Administrative
Agent under Article 2 or Article 3 shall not be effective until delivered.

     SECTION 9.02. No Waivers. No failure or delay by the Administrative Agent
or any Bank in exercising any right, power or privilege hereunder or under any
Note shall operate as a waiver thereof nor shall any single or partial exercise
thereof preclude any other or further exercise thereof or the exercise of any
other

                                       50
<PAGE>

right, power or privilege. The rights and remedies herein provided shall be
cumulative and not exclusive of any rights or remedies provided by law.

     SECTION 9.03. Expenses; Indemnification. (a) The Borrower shall pay (i) all
reasonable out-of-pocket expenses of the Administrative Agent, including
reasonable fees and disbursements of special counsel for the Administrative
Agent, in connection with the preparation of this Agreement, any waiver or
consent hereunder or any amendment hereof or any Default or alleged Default
hereunder and (ii) if an Event of Default occurs, all reasonable out-of-pocket
expenses incurred by the Administrative Agent or any Bank, including reasonable
fees and disbursements of counsel, in connection with such Event of Default and
collection and other enforcement proceedings resulting therefrom.

     (b) The Borrower agrees to indemnify the Administrative Agent and each
Bank, their respective affiliates and the respective directors, officers, agents
and employees of the foregoing (each an "Indemnitee") and hold each Indemnitee
harmless from and against any and all liabilities, losses, damages, costs and
expenses of any kind, including, without limitation, the reasonable fees and
disbursements of counsel, which may be incurred by such Indemnitee in connection
with any investigative, administrative or judicial proceeding (whether or not
such Indemnitee shall be designated a party thereto) relating to or arising out
of this Agreement or any actual or proposed use of proceeds of Loans hereunder;
provided that no Indemnitee shall have the right to be indemnified hereunder for
such Indemnitee's own gross negligence or willful misconduct as determined by a
court of competent jurisdiction.

     SECTION 9.04. Sharing of Set-offs. Each Bank agrees that if it shall, by
exercising any right of set-off or counterclaim or otherwise, receive payment of
a proportion of the aggregate amount then due with respect to the Loans held by
it which is greater than the proportion received by any other Bank in respect
of the aggregate amount then due with respect to the Loans held by such other
Bank, the Bank receiving such proportionately greater payment shall purchase
such participations in the Loans held by the other Banks, and such other
adjustments shall be made, as may be required so that all such payments with
respect to the Loans held by the Banks shall be shared by the Banks pro rata;
provided that nothing in this Section shall impair the right of any Bank to
exercise any right of set-off or counterclaim it may have and to apply the
amount subject to such exercise to the payment of indebtedness of the Borrower
other than its indebtedness under this Agreement.

     SECTION 9.05. Amendments and Waivers. Any provision of this Agreement or
the Notes may be amended or waived if; but only if, such amendment or waiver is
in writing and is signed by the Borrower and the

                                       51
<PAGE>

Required Banks (and, if the rights or duties of the Administrative Agent or the
Swingline Bank are affected thereby, by such Person); provided that no such
amendment or waiver shall, unless signed by all the Banks, (i) increase or
decrease the Commitment of any Bank (except for a ratable decrease in the
Commitments of all Banks) or subject any Bank to any additional obligation, (ii)
reduce the principal of or rate of interest on any Loan or any interest thereon
or any fees hereunder, (iii) postpone the date fixed for any payment of
principal of or interest on any Loan or any fees hereunder or for termination of
any Commitment, (iv) change the percentage of the Commitments or of the
aggregate unpaid principal amount of the Loans, or the number of Banks, which
shall be required for the Banks or any of them to take any action under this
Section or any other provision of this Agreement or (v) change the provisions of
Section 9.04.

     SECTION 9.06. Successors and Assigns. (a) The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns, except that the Borrower may not assign or
otherwise transfer any of its rights under this Agreement without the prior
written consent of all Banks.

     (b) Any Bank may, with the consent (unless an Event of Default then exists)
of the Borrower (such consent not to be unreasonably withheld or delayed), at
any time grant to one or more banks or other institutions (each a "Participant")
participating interests in its Commitment or any or all of its Loans. In the
event of any such grant by a Bank of a participating interest to a Participant,
whether or not upon notice to the Administrative Agent, such Bank shall remain
responsible for the performance of its obligations hereunder, and the Borrower,
the Swingline Bank and the Administrative Agent shall continue to deal solely
and directly with such Bank in connection with such Bank's rights and
obligations under this Agreement. Any agreement pursuant to which any Bank may
grant such a participating interest shall provide that such Bank shall retain
the sole right and responsibility to enforce the obligations of the Borrower
hereunder including, without limitation, the right to approve any amendment,
modification or waiver of any provision of this Agreement; provided that such
participation agreement may provide that such Bank will not agree to any
modification, amendment or waiver of this Agreement described in clause (i),
(ii) or (iii) of Section 9.05 without the consent of the Participant. The
Borrower agrees that each Participant shall, to the extent provided in its
participation agreement, be entitled to the benefits of Article 8 with respect
to its participating interest, subject to the performance by such Participant of
the obligations of a Bank thereunder. An assignment or other transfer which is
not permitted by subsection (c) or (d) below shall be given effect for purposes
of this Agreement only to the extent of a participating interest granted in
accordance with this subsection (b).

                                       52

     (c) Any Bank may at any time assign to one or more banks or other financial
institutions (each an "Assignee") all, or a proportionate part (equivalent to an
initial Commitment of not less than $10,000,000 (unless the Borrower and the
Administrative Agent shall otherwise agree)) of all, of its rights and
obligations under this Agreement and its Note (if any), and such Assignee shall
assume such rights and obligations, pursuant to an Assignment and Assumption
Agreement in substantially the form of Exhibit G hereto executed by such
Assignee and such transferor Bank, with (and only with and subject to) the prior
written consent of the Swingline Bank, the Administrative Agent (which shall not
be unreasonably withheld or delayed) and, so long as no Event of Default has
occurred and is continuing, the Borrower (given in its sole discretion),
provided that unless such assignment is of the entire right, title and interest
of the transferor Bank hereunder, after making any such assignment such
transferor Bank shall have a Commitment of at least $10,000,000 (unless the
Borrower and the Administrative Agent shall otherwise agree). Upon execution and
delivery of such instrument of assumption and payment by such Assignee to such
transferor Bank of an amount equal to the purchase price agreed between such
transferor Bank and such Assignee, such Assignee shall be a Bank party to this
Agreement and shall have all the rights and obligations of a Bank with a
Commitment as set forth in such instrument of assumption, and the transferor
Bank shall be released from its obligations hereunder to a corresponding extent,
and no further consent or action by any party shall be required. Upon the
consummation of any assignment pursuant to this subsection (c), the transferor
Bank, the Administrative Agent and the Borrower shall make appropriate
arrangements so that, if required by the Assignee, a Note is issued to the
Assignee. If the Assignee is not incorporated under the laws of the United
States of America or a state thereof, it shall, prior to the first date on which
interest or fees are payable hereunder for its account, deliver to the Borrower
and the Administrative Agent certification as to exemption from deduction or
withholding of any United States federal income taxes in accordance with Section
8.04. All assignments shall be subject to a transaction fee established by, and
payable by the transferor Bank to, the Administrative Agent for its own account
(which shall not exceed $5,000).

     (d) Any Bank may at any time assign all or any portion of its rights under
this Agreement and its Note (if any) to a Federal Reserve Bank. No such
assignment shall release the transferor Bank from its obligations hereunder or
modify any such obligations.

     (e) No Assignee, Participant or other transferee of any Bank's rights
(including any Applicable Lending Office other than such Bank's initial
Applicable Lending Office) shall be entitled to receive any greater payment
under Section 8.03 or 8.04 than such Bank would have been entitled to receive
with respect to the rights transferred, unless such transfer is made by reason
of the

                                       53
<PAGE>

provisions of Section 8.02, 8.03 or 8.04 requiring such Bank to designate a
different Applicable Lending Office under certain circumstances or at a time
when the circumstances giving rise to such greater payment did not exist.

     SECTION 9.07. Collateral. Each of the Banks represents to the
Administrative Agent and each of the other Banks that it in good faith is not
relying upon any "margin stock" (as defined in Regulation U) as collateral in
the extension or maintenance of the credit provided for in this Agreement.

     SECTION 9.08. Confidentiality. The Administrative Agent and each Bank
agrees to keep any information delivered or made available by the Borrower
pursuant to this Agreement confidential from anyone other than persons employed
or retained by such Bank and its affiliates who are engaged in evaluating,
approving, structuring or administering the credit facility contemplated hereby;
provided that nothing herein shall prevent any Bank from disclosing such
information (a) to any other Bank or to the Administrative Agent, (b) to any
other Person if reasonably incidental to the administration of the credit
facility contemplated hereby, (c) upon the order of any court or administrative
agency, (d) upon the request or demand of any regulatory agency or authority,
(e) which had been publicly disclosed other than as a result of a disclosure by
the Administrative Agent or any Bank prohibited by this Agreement, (f) in
connection with any litigation to which the Administrative Agent, any Bank or
its subsidiaries or Parent may be a party, (g) to the extent necessary in
connection with the exercise of any remedy hereunder, (h) to such Bank's or
Administrative Agent's legal counsel and independent auditors and (i) subject to
provisions substantially similar to those contained in this Section 9.08, to any
actual or proposed Participant or Assignee.

     SECTION 9.09. Governing Law; Submission to Jurisdiction. This Agreement and
each Note (if any) shall be construed in accordance with and governed by the law
of the State of New York. The Borrower hereby submits to the nonexclusive
jurisdiction of the United States District Court for the Southern District of
New York and of any New York State court sitting in New York City for purposes
of all legal proceedings arising out of or relating to this Agreement or the
transactions contemplated hereby. The Borrower irrevocably waives, to the
fullest extent permitted by law, any objection which it may now or hereafter
have to the laying of the venue of any such proceeding brought in such a court
and any claim that any such proceeding brought in such a court has been brought
in an inconvenient forum.

     SECTION 9.10. Counterparts; Integration. This Agreement may be signed in
any number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This

                                       54
<PAGE>

Agreement constitutes the entire agreement and understanding among the parties
hereto and supersedes any and all prior agreements and understandings, oral or
written, relating to the subject matter hereof

     SECTION 9.11. WAIVER OF JURY TRIAL. EACH OF THE BORROWER, THE
ADMINISTRATIVE AGENT, THE SWINGLINE BANK AND THE BANKS, TO THE FULLEST EXTENT IT
MAY EFFECTIVELY DO SO UNDER APPLICABLE LAW, HEREBY IRREVOCABLY WAIVES ANY AND
ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO
THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be

     For purposes of this Schedule, the following terms have the following
meanings:

     "Level I Status" exists at any date if, at such date, the Borrower is rated
higher than "A+" by S&P or higher than "Al" by Moody's.

     "Level II Status" exists at any date if, at such date, (i) the Borrower is
rated "A+" by S&P or "Al" by Moody's and (ii) Level I Status does not exist.

     "Level III Status" exists at any date if, at such date, (i) the Borrower is
rated "A" by S&P or "A2" by Moody's and (ii) neither Level I Status nor Level II
Status exists.

     "Level IV Status" exists at any date if, at such date, (i) the Borrower is
rated "A-" by S&P or "A3" by Moody's and (ii) neither Level I Status, Level II
Status nor Level II Status exists.

     "Level V Status" exists at any date if, at such date, (i) the Borrower is
rated "BBB+" by S&P or "Baal" by Moody's and (ii) neither Level I Status, Level
II Status, Level III Status nor Level IV Status exists.

                                       66
<PAGE>

     "Level VI Status" exists at any date if, at such date, the Borrower is
rated "BBB" by S&P or "Baa2" by Moody's and (ii) neither Level I Status, Level
II Status, Level III Status, Level IV Status nor Level V Status exists.

     "Level VII Status" exists at any date if, at such date, no other Status
exists.

     "Status" refers to the determination of which of Level I Status, Level II
Status, Level III Status, Level IV Status, Level V Status, Level VI Status or
Level VII Status exists at any date. The "Utilization" applicable to any date is
the percentage equivalent of a fraction the numerator of which is the aggregate
outstanding principal amount of the Loans determined at such time after giving
effect, if one or more Loans are being made at such time, to any substantially
concurrent application of the proceeds thereof to repay one or more other Loans
and the denominator of which is the aggregate amount of the Commitments at such
date. If for any reason any Loans remain outstanding following the termination
of the Commitments, Utilization will be deemed to be more than 66 2/3%.

     The credit ratings to be utilized for purposes of this Schedule are those
indicated for or assigned to the senior unsecured long-term debt securities of
the Borrower without third-party credit enhancement, and any rating indicated
for or assigned to any other debt security of the Borrower shall be disregarded.
The ratings in effect for any day are those in effect at the close of business
on such day. A change in credit rating will result in an immediate change in the
applicable Status. In the case of split ratings from S&P and Moody's, the rating
to be used to determine the applicable Status is the higher of the two.

                   OPINION OF GENERAL COUNSEL OF THE BORROWER

                                                                 August 29, 2001

To the Banks and the Administrative Agent
   Referred to Below
c/o The Chase Manhattan Bank
   as Administrative Agent
270 Park Avenue
New York, New York 10017

Ladies and Gentlemen:

     I am the Deputy General Counsel of Duke Energy Corporation (the "Borrower")
and have acted as its counsel in connection with the Three-Year Credit Agreement
(the "Credit Agreement"), dated as of August 29,2001, among the Borrower, the
banks listed on the signature pages thereof, The Chase Manhattan Bank, as
Administrative Agent, and Bank of America, N.A., as Syndication Agent.
Capitalized terms defined in the Credit Agreement are used herein as therein
defined. This opinion letter is being delivered pursuant to Section 3.01(b) of
the Credit Agreement.

     In such capacity, I or attorneys under my direct supervision have examined
originals or copies, certified or otherwise identified to my satisfaction, of
such documents, corporate records, certificates of public officials and other
instruments and have conducted such other investigations of fact and law as I
have deemed necessary or advisable for purposes of this opinion.

     Upon the basis of the foregoing, I am of the opinion that:

     1. The Borrower is a corporation duly incorporated, validly existing and in
good standing under the laws of North Carolina.

     2. The execution, delivery and performance by the Borrower of the Credit
Agreement and any Notes are within the Borrower's corporate powers, have been
duly authorized by all necessary corporate action, require no action by or in
respect of, or filing with, any governmental body, agency or official (except
for the approval of the obtaining of credit pursuant to the Credit Agreement by
the North Carolina Utilities Commission and The Public Service Commission of
South Carolina, which has been obtained) and do not contravene, or constitute a

                                       75
<PAGE>

default under, any provision of applicable law or regulation or of the
certificate of incorporation or by-laws of the Borrower or, to my knowledge, of
any agreement, judgment, injunction, order, decree or other instrument binding
upon the Borrower or, to my knowledge, result in the creation or imposition of
any Lien on any asset of the Borrower or any of its Material Subsidiaries.

     3. Except as, disclosed in the reports referred to in Section 4.04 of the
Credit Agreement, to my knowledge (but without independent investigation), there
is no action suit or proceeding pending or threatened against or affecting, the
Borrower or any of its Subsidiaries before any court or arbitrator or any
governmental body, agency or official, which would be likely to be decided
adversely to the Borrower or such Subsidiary and, as a result, to have a
material adverse effect upon the business, consolidated financial position or
consolidated results of operations of the Borrower and its Consolidated
Subsidiaries, considered as a whole or which in any manner draws into question
the validity of the Credit Agreement or any Notes.

     4. The Borrower is not a holding company under the Public Utility Holding
Company Act of 1935, as amended.

     The phrase "to my knowledge", as used in the foregoing opinion, refers to
my actual knowledge without any independent investigation as to any such
matters.

     I am a member of the Bar of the State of North Carolina and do not express
any opinion herein concerning any law other than the law of the State of North
Carolina and the federal law of the United States of America.

     This opinion is rendered to you in connection with the above-referenced
mater and may not be relied upon by you for any other purpose, or relied upon
by, or furnished to, any other Person, firm or corporation without my prior
written consent, except for Additional Banks and Assignees. My opinions
expressed herein are as of the date hereof, and I undertake no obligation to
advise you of any changes of applicable law or any other matters that may come
to my attention after the date hereof that may affect my opinions expressed
herein.

                                  Very truly yours,

                                   OPINION OF
                       ROBINSON, BRADSHAW & HINSON, P.A.,
                        SPECIAL COUNSEL FOR THE BORROWER

                                                                 August 29, 2001

To the Banks and the Administrative Agent
   Referred to Below
c/o The Chase Manhattan Bank
   as Administrative Agent
270 Park Avenue
New York, New York 10017

Ladies and Gentlemen:

     We have acted as counsel to Duke Energy Corporation, a North Carolina
corporation (the "Borrower"), in connection with the Three-Year Credit
Agreement (the "Credit Agreement"), dated as of August 29, 2001, between the
Duke Energy Corporation, the banks listed on the signature pages thereof, The
Chase Manhattan Bank, as Administrative Agent, and Bank of America, N.A., as
Syndication Agent. Capitalized terms used herein and not defined shall have the
meanings given to them in the Credit Agreement. This opinion letter is being
delivered pursuant to Section 3.01(b) of the Credit Agreement.

     In connection with this opinion, we also examined originals, or copies
identified to our satisfaction, of such other documents and considered such
matters of law and fact as we, in our professional judgment, have deemed
appropriate to render the opinions contained herein. Where we have considered it
appropriate, as to certain facts we have relied, without investigation or
analysis of any underlying data contained therein, upon certificates or other
comparable documents of public officials and officers or other appropriate
representatives of the Borrower.

     In rendering the opinions contained herein, we have assumed, among other
things, that the Credit Agreement and any Notes to be executed (i) are within
the Borrower's corporate powers, (ii) have been duly authorized by all necessary
corporate action, (iii) require no action by or in respect of; or filing with,
any governmental body, agency of official, and (iv) do not contravene, or
constitute a default under, any provision of applicable law or regulation or of
the Borrower's

                                       77
<PAGE>

certificate of incorporation or by-laws or any agreement, judgment, injunction,
order, decree or other instrument binding upon the Borrower or result in the
creation or imposition of any Lien on any asset of the Borrower. In addition, we
have assumed that the Credit Agreement fully states the agreement between the
Borrower and the Banks with respect to the matters addressed therein, and that
the Credit Agreement constitutes a legal, valid and binding obligation of each
Bank, enforceable in accordance with its respective terms.

     The opinions set forth herein are limited to matters governed by the laws
of the State of North Carolina and the federal laws of the United States, and no
opinion is expressed herein as to the laws of any other jurisdiction. For
purposes of our opinions, we have disregarded the choice of law provisions in
the Credit Agreement and, instead, have assumed with your permission that the
Credit Agreement and the Notes are governed exclusively by the internal,
substantive laws and judicial interpretations of the State of North Carolina. We
express no opinion concerning any matter respecting or affected by any laws
other than laws that a lawyer in North Carolina exercising customary
professional diligence would reasonably recognize as being directly applicable
to the Borrower, the Loans, the Letters of Credit, or any of them.

     Based upon and subject to the foregoing and the further limitations and
qualifications hereinafter expressed, it is our opinion that the Credit
Agreement constitutes the legal, valid and binding obligation of the Borrower
and the Notes, if and when issued, will constitute legal, valid and binding
obligations of the Borrower, in each case, enforceable against the Borrower in
accordance with its terms.

     The opinions expressed above are subject to the following qualifications
and limitations:

     1. Enforcement of the Credit Agreement and the Notes is subject to the
effect of applicable bankruptcy, insolvency, reorganization, fraudulent
conveyance, moratorium and similar laws affecting the enforcement of creditors'
rights generally.

     2. Enforcement of the Credit Agreement and the Notes is subject to the
effect of general principles of equity (regardless of whether considered in a
proceeding in equity or at law) by which a court with proper jurisdiction may
deny rights of specific performance, injunction, self-help, possessory remedies
or other remedies.

     3. We do not express any opinion as to the enforceability of any
provisions contained in the Credit Agreement or any Note that (i) purport to
excuse a party for liability for its own acts, (ii) purport to make void any act
done

                                       78
<PAGE>

in contravention thereof, (iii) purport to authorize a party to act in its sole
discretion, (iv) require waivers or amendments to be made only in writing, (v)
purport to effect waivers of constitutional, statutory or equitable rights or
the effect of applicable laws, (vi) impose liquidated damages, penalties or
forfeiture, or (vii) purport to indemnify a party for its own negligence or
willful misconduct. Indemnification provisions in the Credit Agreement are
subject to and may be rendered unenforceable by applicable law or public policy,
including applicable securities law.

     4. We do not express any opinion as to the enforceability of any provisions
contained in the Credit Agreement or the Notes purporting to require a party
thereto to pay or reimburse attorneys' fees incurred by another party, or to
indemnify another party there for, which may be limited by applicable statutes
and decisions relating to the collection and award of attorneys' fees, including
but not limited to North Carolina General Statutes ss. 6-21.2.

     5. We do not express any opinion as to the enforceability of any provisions
contained in the Credit Agreement purporting to waive the fight of jury trial.
Under North Carolina General Statutes ss. 22B-l0, a provision for the waiver of
the right to a jury trial is unconscionable and unenforceable.

     6. We do not express any opinion as to the enforceability of any provisions
contained in the Credit Agreement concerning choice of forum or consent to the
jurisdiction of courts, venue of actions or means of service of process.

     7. It is likely that North Carolina courts will enforce the provisions of
the Credit Agreement providing for interest at a higher rate resulting from a
Default or Event of Default (a "Default Rate") which rate is higher than the
rate otherwise stipulated in the Credit Agreement. The law, however, disfavors
penalties, and it is possible that interest at the Default Rate may be held to
be an unenforceable penalty, to the extent such rate exceeds the rate applicable
prior to a default under the Credit Agreement. Also, since North Carolina
General Statutes ss. 24-10.1 expressly provides for late charges, it is possible
that North Carolina courts, when faced specifically with the issue, might rule
that this statutory late charge preempts any other charge (such as default
interest) by a bank for delinquent payments. The only North Carolina case which
we have found that addresses this issue is a 1978 Court of Appeals decision,
which in our opinion is of limited precedential value, North Carolina National
Rank V. Burnette, 38 N.C. App. 120,247 S.E.2d 648(1978), rev'd on other grounds,
297 N.C. 524,256 S.E.2d 388 (1979). While the court in that case did allow
interest after default (commencing with the date requested in the complaint) at
a rate six percent in excess of pre-default interest, we are unable to determine
from the opinion that any question was raised as to this being penal in nature,
nor does the court address

                                       79
<PAGE>

the possible question of the statutory late charge preempting a default interest
surcharge. Therefore, since the North Carolina Supreme Court has not ruled in a
properly presented case raising issues of its possible penal nature and those of
North Carolina General Statutes ss. 24-10.1, we are unwilling to express an
unqualified opinion that the Default Rate of interest prescribed in the Credit
Agreement is enforceable.

     8. We do not express any opinion as to the enforceability of any
provisions contained in the Credit Agreement relating to evidentiary standards
or other standards by which the Credit Agreement are to be construed.

     This opinion letter is delivered solely for your benefit in connection with
the Credit Agreement and, except for any Additional Bank or any Assignee which
becomes a Bank pursuant to Section 9.06(c) of the Credit Agreement, may not be
used or relied upon by any other Person or for any other purpose without our
prior written consent in each instance. Our opinions expressed herein are as of
the date hereof; and we undertake no obligation to advise you of any changes of
applicable law or any other matters that may come to our attention after the
date hereof that may affect our opinions expressed herein.

                                  Very truly yours,

                                   OPINION OF

To the Banks and the Administrative Agent
 Referred to Below
c/o The Chase Manhattan Bank,
as Administrative Agent
270 Park Avenue
New York, New York 10017

Dear Sirs:

     We have participated in the preparation of the Three-Year Credit Agreement
(the "Credit Agreement') dated as of August 29,2001 among Duke Energy
Corporation, a North Carolina corporation (the "Borrower"), the banks listed on
the signature pages thereof (the "Banks"), Bank of America, NA., as Syndication
Agent, and The Chase Manhattan Bank, as Administrative Agent (the
"Administrative Agent"), and have acted as special counsel for the
Administrative Agent for the purpose of rendering this opinion pursuant to
Section 3.01(c) of the Credit Agreement. Terms defined in the Credit Agreement
are used herein as therein defined.

     We have examined originals or copies, certified or otherwise identified to
our satisfaction, of such documents, corporate records, certificates of public
officials and other instruments and have conducted such other investigations of
fact and law as we have deemed necessary or advisable for purposes of this
opinion.

     Upon the basis of the foregoing, we are of the opinion that:

     1. The execution, delivery and performance by the Borrower of the Credit
Agreement and the Notes are within the Borrower's corporate powers and have been
duly authorized by all necessary corporate action.

     2. The Credit Agreement constitutes a valid and binding agreement of the
Borrower and the Notes, if and when issued, constitute valid and binding
obligations of the Borrower enforceable in accordance with their respective
terms,

                                       81
<PAGE>

except as the same may be limited by bankruptcy, insolvency or similar laws
affecting creditors' rights generally and by general principles of equity.

     In giving the foregoing opinion, (i) we express no opinion as to the effect
(if any) of any law of any jurisdiction (except the State of New York) in which
any Bank is located which limits the rate of interest that such Bank may charge
or collect and (ii) we have relied, without independent investigation, as to all
matters governed by the laws of North Carolina, upon the opinion of the General
Counsel of the Borrower, dated August 29,2001, a copy of which has been
delivered to you.

     This opinion is rendered solely to you in connection with the above matter.
This opinion may not be relied upon by you for any other purpose or relied upon
by or furnished to any other person, firm or corporation without our prior
written consent, except for Additional Banks and all Participants.

                                  Very truly yours,

                      ASSIGNMENT AND ASSUMPTION AGREEMENT

     AGREEMENT dated as of _______, 20__ among [ASSIGNOR] (the "Assignor"),
[ASSIGNEE] (the "Assignee"), [DUKE ENERGY CORPORATION,] THE CHASE MANHATTAN
HANK, as Swingline Bank, and THE CHASE MANHATTAN BANK, as Administrative Agent
(the "Administrative Agent").

                                   WITNESSETH

     WHEREAS, this Assignment and Assumption Agreement (the "Agreement") relates
to the Three-Year Credit Agreement dated as of August 29, 2001 among Duke Energy
Corporation (the "Borrower"), the Assignor and the other Banks party thereto, as
Banks, Bank of America, N.A., as Syndication Agent, and the Administrative Agent
(the "Credit Agreement");

     WHEREAS, as provided under the Credit Agreement, the Assignor has a
Commitment to make Loans to the Borrower in an aggregate principal amount at any
time outstanding not to exceed $__________;*

     WHEREAS, Syndicated Loans made to the Borrower by the Assignor under the
Credit Agreement in the aggregate principal amount of $___________ are
outstanding at the date hereof; and

     WHEREAS, the Assignor proposes to assign to the Assignee all of the rights
of the Assignor under the Credit Agreement in respect of a portion of its
Commitment thereunder in an amount equal to $__________ (the "Assigned Amount"),
together with a corresponding portion of its outstanding Committed Loans, and
the Assignee proposes to accept assignment of such rights and assume the
corresponding obligations from the Assignor on such terms;*

     NOW, THEREFORE, in consideration of the foregoing and the mutual agreements
contained herein, the parties hereto agree as follows:

     SECTION I. Definitions. All capitalized terms not otherwise defined herein
shall have the respective meanings set forth in the Credit Agreement.

------------------------------
     *The asterisked provisions shall be appropriately revised in the event of
an assignment after the Commitment Termination Date.

                                       83
<PAGE>

     SECTION 2. Assignment. The Assignor hereby assigns and sells to the
Assignee all of the rights of the Assignor under the Credit Agreement to the
extent of the Assigned Amount, and the Assignee hereby accepts such assignment
from the Assignor and assumes all of the obligations of the Assignor under the
Credit Agreement to the extent of the Assigned Amount, including the purchase
from the Assignor of the corresponding portion of the principal amount of the
Syndicated Loans made by the Assignor outstanding at the date hereof. Upon the
execution and delivery hereof by the Assignor, the Assignee, [the Borrower,] the
Swingline Bank and the Administrative Agent, the payment of the amounts
specified in Section 3 required to be paid on the date hereof (i) the Assignee
shall, as of the date hereof, succeed to the rights and be obligated to perform
the obligations of a Bank under the Credit Agreement with a Commitment in an
amount equal to the Assigned Amount, and (ii) the Commitment of the Assignor
shall, as of the date hereof, be reduced by a like amount and the Assignor
released from its obligations under the Credit Agreement to the extent such
obligations have been assumed by the Assignee. The assignment provided for
herein shall be without recourse to the Assignor.

     SECTION 3. Payments. As consideration for the assignment and sale
contemplated in Section 2 hereof, the Assignee shall pay to the Assignor on the
date hereof in Federal funds the amount heretofore agreed between them.* It is
understood that facility fees accrued to the date hereof in respect of the
Assigned Amount are for the account of the Assignor and such fees accruing from
and including the date hereof are for the account of the Assignee. Each of the
Assignor and the Assignee hereby agrees that if it receives any amount under the
Credit Agreement which is for the account of the other party hereto, it shall

            light of the circumstances in which it is furnished.

      (c)   Each of Duke Energy and Westcoast shall promptly notify the other if
            at any time before or after the Effective Time it becomes aware that
            the Circular or an application for an order or a registration
            statement described in Section 2.6 contains any misrepresentation
            (as defined in the Securities Act) or any untrue statement of a
            material fact or omits to state a material fact required to be
            stated therein or necessary to make the statements contained therein
            not misleading in light of the circumstances in which they are made,
            or that otherwise requires an amendment or supplement to the
            Circular or such application or registration statement. In any such
            event, Duke Energy and Westcoast shall cooperate in the preparation
            of a supplement or amendment to the Circular or such other document,
            as required and as the case may be, and, if required, shall cause
            the same to be distributed to the Westcoast Securityholders or filed
            with the relevant securities regulatory authorities.

      (d)   Westcoast shall ensure that the Circular complies with all
            applicable Laws and, without limiting the generality of the

            material fact or omit to state a material fact required to be stated
            therein or necessary to make the statements contained therein not

            information in sufficient detail to permit them to form a reasoned
            judgment concerning the matters to be placed before them at the
            Westcoast Meeting.

            its businesses as currently owned and conducted except where,
            individually or in the aggregate, the failure of a subsidiary other
            than a Material Subsidiary to be so organized, formed or existing or
            to have such power or authority would not have a Material Adverse
            Effect on Westcoast. Each of Westcoast and its subsidiaries is duly
            qualified to do business in each jurisdiction in which the nature of
            the business conducted by it or the ownership or leasing of its
            properties requires it to so qualify, except where, individually or
            in the aggregate, the failure to be so qualified would not have a
            Material Adverse Effect on Westcoast.

            to or make any investment in (in the form of a loan, capital
            contribution or otherwise) any subsidiary, Partially Owned Entity or
            other person other than Westcoast or a wholly owned subsidiary of
            Westcoast.

            failure of the shares or ownership interest in a subsidiary other
            than a Material Subsidiary to be so authorized or issued or owned
            free and clear would not have a Material Adverse Effect on
            Westcoast.

            none of Westcoast or any of its subsidiaries, or, to the knowledge
            of Westcoast, its Partially Owned Entities, has engaged in any
            conduct that is proscribed during the Pre-Effective Date Period by
            Section 5.1.

3.7   Employment Matters

      (a)   Except as set forth in the management proxy circular prepared in
            connection with the Annual Meeting of Westcoast held on April 25,
            2001 or Section 3.7 of the Westcoast Disclosure Letter, neither
            Westcoast nor any of its subsidiaries is a party to any written or
            oral policy, agreement, obligation or understanding providing for
            severance or termination payments to, or any employment agreement
            with, any former or current director, officer or employee other than
            any agreement which applies to only one individual and which does
            not provide for payment to such individual in excess of $150,000 in
            any one calendar year and other than as required by applicable Law
            for employees without agreements as to notice or severance or
            pursuant to collective bargaining agreements.

                  AMENDED AND RESTATED COMBINATION AGREEMENT

      (b)   Neither Westcoast nor any of its subsidiaries is a party to any
            consulting contract, written or oral, providing for compensation of
            any individual in excess of $350,000 per calendar year.

      (c)   Neither Westcoast nor any of its subsidiaries has agreed to
            recognize any union or other collective bargaining representative,
            nor has any union or other collective bargaining representative been
            certified as the exclusive bargaining representative of any of
            Westcoast's or any of its subsidiaries' employees. No labor union or
            representative of the employees of Westcoast or any of its
            subsidiaries claims to be seeking to represent employees of
            Westcoast or any of its subsidiaries other than those that are
            parties to executed collective bargaining agreements identified in
            Section 3.7 of the Westcoast Disclosure Letter. To the knowledge of
            Westcoast, no union organizational campaign or representation
            petitions are currently pending with respect to any of the employees
            of Westcoast or any of its subsidiaries or Partially Owned Entities.
            Neither Westcoast nor any of its subsidiaries is a party to, or
            bound by, any collective bargaining agreement or any other labor
            contract applicable to any employees of Westcoast or its
            subsidiaries. All collective bargaining agreements to which
            Westcoast is a party have been duly ratified and there are no
            written or oral agreements which modify the terms of any such
            collective bargaining agreement. No collective bargaining agreements
            or other labor contracts relating to employees of Westcoast or its
            subsidiaries are being negotiated. To the knowledge of Westcoast,
            neither Westcoast nor any of its subsidiaries have breached any of
            their obligations under any collective bargaining agreements that
            would have a Material Adverse Effect on Westcoast. There is no labor
            strike or labor dispute, slowdown, lockout or stoppage actually
            pending or threatened against or affecting Westcoast or its
            subsidiaries, individually or in the aggregate, that would be
            reasonably expected to have a Material Adverse Effect on Westcoast,
            and Westcoast and its subsidiaries have not experienced any labor
            strikes or labor disputes, slowdowns, lockouts or stoppages since
            December 31, 1998, that had a Material Adverse Effect on Westcoast.
            To the knowledge of Westcoast, no union or collective bargaining
            representative has applied to have Westcoast or any of its
            subsidiaries declared a related or successor employer pursuant to
            applicable labor Laws.

      (d)   All employees and former employees of Westcoast and its subsidiaries
            have been, or will have been on or before the Effective Date, paid
            or amounts in respect thereof shall have been accrued for wages,
            salaries, commissions, bonuses, vacation pay, severance and
            termination pay, sick pay, and other compensation for all services
            performed by them or that was accrued by them up to the Effective
            Date, in accordance with the obligations of Westcoast and its
            subsidiaries under any employment or labor practices and policies or
            any collective bargaining agreement or individual agreement to which
            Westcoast or its subsidiaries is a party, or by which Westcoast or
            its subsidiaries may be bound, except for, in the case of severance
            and termination pay, statutory and common law requirements for
            payment in lieu of reasonable notice of termination.

      (e)   There are no current, pending or, to the knowledge of Westcoast,
            threatened proceedings before any board or tribunal or claims with
            respect to employment and

                  AMENDED AND RESTATED COMBINATION AGREEMENT

            labor Laws, including, but not limited to, employment and labor
            standards, unfair labor practices, employment discrimination,
            occupational health and safety, employment equity, pay equity,
            workers' compensation, human rights and labor relations, other than
            such proceedings and claims which, individually or in the aggregate,
            would not have a Material Adverse Effect on Westcoast. Westcoast and
            its subsidiaries are not subject to any settlement agreement,
            conciliation agreement, letter of commitment, deficiency letter or
            consent decree with any present or former employee or applicant for
            employment, labor union or other employee representative, or any
            Government Entity or arbitrator relating to claims of unfair labor
            practices, employment discrimination, or other claims with respect
            to employment and labor practices and policies that would have a
            Material Adverse Effect on Westcoast, and no Government Entity or
            arbitrator has issued a judgment, order, decree, injunction,
            decision, award or finding with respect to the employment and labor
            practices or policies of Westcoast or its subsidiaries which
            currently has or would be reasonably expected to have a Material
            Adverse Effect on Westcoast. There are no outstanding assessments,
            penalties, fines, liens, charges, surcharges, or other amounts due
            and owing pursuant to any workplace safety and insurance legislation
            by Westcoast or any of its subsidiaries and they have not been
            reassessed in any material respect under such legislation during the
            past three years and, to the knowledge of Westcoast, no audit is
            currently being performed pursuant to any applicable workplace
            safety and insurance legislation. There are no claims or, to the
            knowledge of Westcoast, potential claims which may materially and
            adversely affect accident cost experience.

3.8   Reports; Financial Statements

      (a)   Since January 1, 1998, Westcoast and its subsidiaries have timely
            filed all forms, reports, schedules, statements and other documents
            required to be filed with (i) Canadian securities regulatory
            authorities (collectively the "Westcoast SRA Reports"), (ii) the SEC
            under the Exchange Act or the 1933 Act (collectively the "Westcoast
            SEC Reports"), (iii) any other applicable state, provincial or
            territorial securities authority, and (iv) any other Governmental
            Entity, except in each case where the failure to file any such
            forms, reports, schedules, statements or other documents would not
            have a Material Adverse Effect on Westcoast (all such forms,
            reports, schedules, statements and other documents are collectively
            referred to as the "Westcoast Documents"). The Westcoast Documents
            at the time filed (x) did not contain any misrepresentation (as
            defined in the Securities Act), (y) did not contain any untrue
            statement of a material fact or omit to state a material fact
            required to be stated therein or necessary in order to make the
            statements contained therein not misleading in light of the
            circumstances under which they were made and (z) complied in all
            material respects with the requirements of applicable Laws
            (including, with respect to the Westcoast SEC Reports, the 1933 Act,
            the Exchange Act and the rules and regulations thereunder).
            Westcoast has not filed any confidential material change report with
            the OSC or any other securities authority or regulator or any stock
            exchange or other self-regulatory authority that at the date hereof
            remains confidential.

                  AMENDED AND RESTATED COMBINATION AGREEMENT
                                       21
<PAGE>

      (b)   The consolidated financial statements (including, in each case, any
            related notes thereto) contained in any Westcoast SRA Reports or
            Westcoast SEC Reports (i) have been prepared in accordance with
            Canadian generally accepted accounting principles applied on a
            consistent basis during the periods involved (subject, in the case
            of unaudited financial statements, to the absence of notes in the
            case of Westcoast SRA Reports filed prior to the implementation of
            OSC Rule 51-501), (ii) complied in all material respects with the
            requirements of applicable securities Laws, and (iii) fairly
            present, in all material respects, the consolidated financial
            position, results of operations and cash flows of Westcoast and its
            subsidiaries as of the respective dates thereof and for the
            respective periods covered thereby, subject, in the case of
            unaudited financial statements, to normal, recurring audit
            adjustments none of which will be material.

      (c)   From January 1, 1998 to the date of this Agreement, there has been
            no change by Westcoast or its subsidiaries in their accounting
            policies, methods, practices or principles that are material to
            Westcoast's consolidated financial statements, except as described
            in the notes thereto with respect to periods ending prior to the
            date hereof.

relating to the borrowing of money by Westcoast or its subsidiaries in excess of

its subsidiaries involving more than $100 million per year or $250 million over

material to the business or operations of Westcoast and its subsidiaries are
valid and binding obligations of Westcoast or such subsidiaries that are parties
thereto and, to the knowledge of Westcoast, the valid and binding obligation of
each other party thereto except such contracts which if not so valid and binding
would not, individually or in the aggregate, have a Material Adverse Effect on
Westcoast.

3.10  Litigation

      There are no claims, actions, proceedings or investigations pending or, to
the knowledge of Westcoast, threatened against Westcoast or any of its
subsidiaries or Partially Owned Entities before any Governmental Entity (and
Westcoast, its subsidiaries and, to the knowledge of Westcoast, its Partially
Owned Entities, have no knowledge of any facts that are likely to give rise to
any such claim, action, proceeding or investigation) that would be reasonably
expected to have a Material Adverse Effect on Westcoast, or prevent or
materially delay consummation of the transactions contemplated by this
Agreement. Neither Westcoast nor any of its subsidiaries, nor their respective
assets and properties, is subject to any outstanding judgment, order, writ,
injunction or decree that has had or would be reasonably expected to have a
Material Adverse Effect on Westcoast or that would prevent or materially delay
consummation of the transactions contemplated by this Agreement.

3.11  Environmental

      Except for any matters which individually or in the aggregate are not
reasonably likely to result in an expenditure or liability in excess of $20
million:

      (a)   all operations of Westcoast and its subsidiaries and, to the
            knowledge of Westcoast, any of its Partially Owned Entities have
            been conducted, and are now, in compliance with all Environmental
            Laws;

      (b)   Westcoast and its subsidiaries and, to the knowledge of Westcoast,
            its Partially Owned Entities are in possession of, and in compliance
            with, all permits, authorizations, certificates, registrations,
            approvals and consents necessary under Environmental Laws to own,
            lease and operate their properties and to conduct their respective
            businesses as they are now being conducted or as proposed to be
            conducted (collectively the "Westcoast Environmental Permits"); and

      (c)   neither Westcoast nor any of its subsidiaries or, to the knowledge
            of Westcoast, any of its Partially Owned Entities is subject to:

                  AMENDED AND RESTATED COMBINATION AGREEMENT
                                       23
<PAGE>

            (i)   any Environmental Laws that require any work, repairs,
                  construction, change in business practices or operations, or
                  expenditures, including capital expenditures for facility
                  upgrades, environmental investigation and remediation
                  expenditures, or any other such expenditures;

            (ii)  any written demand or written notice alleging breach of or
                  with respect to liability under any Environmental Laws
                  applicable to Westcoast, any subsidiary of Westcoast or any of
                  its Partially Owned Entities, including any regulations
                  respecting the use, storage, treatment, transportation or
                  disposition (including disposal or arranging for disposal) of
                  Hazardous Substances;

            (iii) any written demand or written notice with respect to
                  liability, by contract or operation of Environmental Laws
                  applicable to Westcoast or any current or former subsidiary of
                  Westcoast or any of its Partially Owned Entities or any of
                  their respective predecessor entities, divisions or any
                  formerly owned, leased or operated properties or assets of the
                  foregoing, including liability with respect to the presence,
                  release, threatened release or discharge of Hazardous
                  Substances; or

            (iv)  any changes in the terms or conditions of any Westcoast

                  revocation, reissuance, alteration or amendment of such
                  Westcoast Environmental Permits that are required in
                  connection with the execution or delivery of this Agreement,
                  the consummation of the transactions contemplated hereby or
                  the continuation of business of Westcoast or any subsidiaries
                  of Westcoast or, to the knowledge of Westcoast, any of its
                  Partially Owned Entities following such consummation.

3.12  Tax Matters

      (a)   Westcoast and each of its subsidiaries have timely filed, or caused
            to be filed, all material Tax Returns required to be filed by them
            (all of which returns were correct and complete in all material
            respects), have timely paid, or caused to be paid, Taxes shown to be
            due and payable thereon, and have satisfied in full in all respects
            all Tax withholding, deposit and remittance requirements imposed on
            or with respect to any of Westcoast and its subsidiaries, and
            Westcoast's most recently published financial statements contain an
            adequate provision in accordance with Canadian generally accepted
            accounting principles for all material amounts of Taxes payable in
            respect of each period covered by such financial statements and all
            prior periods to the extent such Taxes have not been paid, whether
            or not due and whether or not shown as being due on any Tax Returns.
            Westcoast and each of its subsidiaries have made adequate provision
            in accordance with Canadian generally accepted accounting principles
            in their books and records for any amount of Taxes material to
            Westcoast on a consolidated basis and accruing in respect of any
            accounting period ending subsequent to the period covered by such
            financial statements.

      (b)   Neither Westcoast nor any subsidiary of Westcoast has received any
            written notification that any issue involving an amount of Taxes
            material to Westcoast on a

                  AMENDED AND RESTATED COMBINATION AGREEMENT

                                       24
<PAGE>

            consolidated basis has been raised (and is currently pending) by the
            Canada Customs and Revenue Agency, the United States Internal
            Revenue Service or any other taxing authority, including, without
            limitation, any sales tax authority, in connection with any of the
            Tax Returns filed or required to be filed, and no waivers of
            statutes of limitations or objections to any assessments or
            reassessments involving an amount of Taxes material to Westcoast on
            a consolidated basis have been given, filed or requested with
            respect to Westcoast or any subsidiary of Westcoast. All liability
            of Westcoast and its subsidiaries for Canadian federal and
            provincial income and capital taxes has been assessed by the Canada
            Customs and Revenue Agency and, where applicable, Canadian
            provincial tax authorities for all fiscal years up to and including
            the fiscal year ended December 31, 1999. Neither Westcoast nor any
            of its subsidiaries has received any notice from any taxing
            authority to the effect that any Tax Return is being examined, and
            Westcoast has no knowledge of any Tax audit or issue that would be
            reasonably expected to have a Material Adverse Effect on Westcoast.
            There are no proposed (but unassessed) additional Taxes applicable
            to Westcoast or any of its subsidiaries or, to the knowledge of
            Westcoast, any of its Partially Owned Entities, involving an amount
            of Taxes material to Westcoast on a consolidated basis and none has
            been asserted against Westcoast or any of its subsidiaries or, to
            the knowledge of Westcoast, any of its Partially Owned Entities.
            There are no Tax liens on any assets of Westcoast or any of its
            subsidiaries except for Taxes not yet due and payable and those
            which would not be reasonably expected to result in a Material
            Adverse Effect on Westcoast. Neither Westcoast nor any of its
            subsidiaries has received a refund of any Taxes to which it was not
            entitled. Neither Westcoast nor any of its subsidiaries (i) has made
            an election to be treated as a "consenting corporation" under
            Section 341(f) of the United States Internal Revenue Code of 1986
            (the "Code") or (ii) is a party to any Tax sharing or other similar
            agreement or arrangement or any Tax indemnification agreement of any
            nature with any other person (other than in agreements with
            Westcoast or any of its subsidiaries) pursuant to which Westcoast or
            any of its subsidiaries has or could have any material liabilities
            in respect of Taxes. Westcoast has not made an election under
            Section 897(i) of the Code to be treated as a domestic corporation
            for purposes of Sections 897, 1445 and 6039C of the Code.

      (c)   "Tax" and "Taxes" means, with respect to any person, all income
            taxes (including any tax on or based upon net income, gross income,
            income as specially defined, earnings, profits or selected items of
            income, earnings or profits) and all capital taxes, gross receipts
            taxes, environmental taxes, sales taxes, use taxes, ad valorem
            taxes, value added taxes, transfer taxes, franchise taxes, license
            taxes, withholding taxes, payroll taxes, employment taxes, pension

3.13  Pension and Employee Benefits

      (a)   Section 3.13 of the Westcoast Disclosure Letter sets forth a list of
            all employee benefit, health, welfare, supplemental unemployment
            benefit, bonus, incentive, pension, profit sharing, deferred
            compensation, stock compensation, stock option, stock purchase,
            retirement, hospitalization insurance, medical, dental, legal,
            disability and similar plans or arrangements or practices, whether
            written or oral, which are sponsored, maintained or contributed to
            by Westcoast or any of its subsidiaries (collectively referred to as
            the "Westcoast Plans"). The Westcoast Disclosure Letter states which
            of the Westcoast Plans are subject to the provisions of the United
            States Employee Retirement Income Security Act of 1974, as amended
            ("ERISA"). For purposes of this Section 3.13, a subsidiary of
            Westcoast shall be deemed to also include each corporation, trade,
            business, or entity that would be considered to be a single employer
            or under common control with Westcoast pursuant to Section 414 of
            the Code or Section 4001 of ERISA.

      (b)   No step has been taken, no event has occurred and no condition or
            circumstance exists that has resulted in or could be reasonably
            expected to result in any Westcoast Plan being ordered or required
            to be terminated or wound up in whole or in part or having its
            registration under applicable Laws refused or revoked, or being
            placed under the administration of any trustee or receiver or
            regulatory authority or being required to pay any material amount of
            Taxes, fees, penalties or levies under applicable Laws. There are no
            actions, suits, claims (other than routine claims for payment of
            benefits in the ordinary course), trials, demands, investigations,
            arbitrations or other proceedings which are pending or threatened in
            respect of any of the Westcoast Plans or their assets which
            individually or in the aggregate would have a Material Adverse
            Effect on Westcoast.

      (c)   Westcoast has provided to Duke Energy true, correct and complete
            copies of all of the Westcoast Plans as amended (or, in the case of
            any unwritten Westcoast Plan, a description thereof) together with
            all related actuarial reports, and Westcoast has made available to
            Duke Energy all other related documentation including, without
            limitation, funding agreements, trust agreements, funding and
            financial information returns and statements with respect to each
            Westcoast Plan, and current plan summaries, booklets and personnel
            manuals. Westcoast has provided to Duke Energy a true and complete
            copy of (i) the most recent annual report on Form 5500 filed with
            the United States Internal Revenue Service with respect to each
            Westcoast Plan in respect of which such a report was required and
            (ii) the most recent annual information return filed with the Canada
            Customs and Revenue Agency with respect to each Westcoast Plan in
            respect of which such a return was required.

      (d)   All of the Westcoast Plans are and have been established,
            registered, qualified, invested and administered, in all material
            respects, in accordance with all applicable Laws, and in accordance
            with their terms and the terms of agreements between Westcoast or a
            subsidiary of Westcoast, as the case may be, and their respective
            employees. No fact or circumstance exists that could adversely
            affect the existing tax status of a Westcoast Plan.

                  AMENDED AND RESTATED COMBINATION AGREEMENT
                                       26
<PAGE>

      (e)   All obligations of Westcoast or a subsidiary of Westcoast regarding
            the Westcoast Plans have been satisfied in all material respects.
            All contributions or premiums required to be made by Westcoast or a
            subsidiary of Westcoast, as the case may be, under the terms of each
            Westcoast Plan or by applicable Laws have been made in a timely
            fashion in accordance with applicable Laws and the terms of the
            Westcoast Plans.

      (f)   Each Westcoast Plan is fully insured or fully funded (both on a
            going-concern and solvency basis) and in good standing with such
            regulatory authorities as may be applicable and, as of the date
            hereof, no notice of underfunding, noncompliance, failure to be in
            good standing or otherwise has been received by Westcoast or its
            subsidiaries from any such regulatory authority.

      (g)   There have been no improper withdrawals, applications or transfers
            of assets from any Westcoast Plan or the trusts or other funding
            media relating thereto that remain outstanding and unremedied, and
            neither Westcoast, nor any subsidiary of Westcoast, nor, to the
            knowledge of Westcoast, any of their respective agents has been in
            breach of any fiduciary obligation with respect to the
            administration of the Westcoast Plans or the trusts or other funding
            media relating thereto.

      (h)   Westcoast or its subsidiaries may unilaterally amend or terminate,
            in whole or in part, each Westcoast Plan and take contribution
            holidays under or withdraw surplus from each Westcoast Plan, subject
            only to approvals required by Law and, with respect to amendment or
            termination, the collective agreements disclosed in Section 3.7 of
            the Westcoast Disclosure Letter.

      (i)   No commitments to improve or otherwise amend any Westcoast Plan have
            been made except as required by applicable Laws.

      (j)   None of the Westcoast Plans (other than pension plans) provide
            benefits to retired or former employees or to the beneficiaries or
            dependants of retired or former employees.

      (k)   No insurance policy or any other contract or agreement affecting any
            Westcoast Plan requires or permits a retroactive increase in
            premiums or payments due thereunder.

      (l)   All Westcoast Plans intended to be tax-qualified in the United
            States have been the subject of determination letters from the
            United States Internal Revenue Service to the effect that such
            Westcoast Plans and their related trusts are qualified and exempt
            from United States Federal income taxes under Sections 401(a) and
            501(a), respectively, of the Code, and no such determination letter
            has been revoked nor, to the knowledge of Westcoast, has revocation
            been threatened, nor has any such Westcoast Plan been amended since
            the date of its most recent determination letter or application
            therefor in any respect that would adversely affect its
            qualification or materially increase its costs and nothing has
            occurred since the date of such letter that could adversely affect
            the qualified status of such plan. As to any such Westcoast

                  AMENDED AND RESTATED COMBINATION AGREEMENT
                                       27
<PAGE>

            Plan, there has been no termination or partial termination of such
            Westcoast Plan within the meaning of Section 411(d)(3) of the Code.

      (m)   No amount or benefit that could be received (whether in cash or
            property, the vesting of property or the acceleration of the
            exerciseability of stock options) as a result of or in connection
            with the transactions contemplated by this Agreement or the
            Arrangement (whether or not some other subsequent action or event
            would be required to cause the receipt of such amount or benefit to
            occur) by any employee, officer or director of Westcoast or any of
            its affiliates who is a "disqualified individual" (as such term is
            defined in proposed United States Treasury Regulation Section
            1.280G-1) under any employment, severance or termination agreement,
            other compensation arrangement or Westcoast Plan currently in effect
            will fail to be deductible for United States federal income tax
            purposes by virtue of Section 280G of the Code.

      (n)   None of the Westcoast Plans is a "multiemployer plan" within the
            meaning of Section 4001(a)(3) of ERISA or any other applicable Law,
            nor has Westcoast or any subsidiary of Westcoast been obligated to
            contribute to any such multiemployer plan at any time within the
            past six years.

      (o)   No employment, severance or termination agreement, other
            compensation arrangement or Westcoast Plan provides for payment of a
            benefit, the increase of a benefit amount, the acceleration of
            contributions or funding, the payment of a contingent benefit or the
            acceleration of the payment or vesting of a benefit by reason of the
            execution of this Agreement or the consummation of the transactions
            contemplated by this Agreement or the Arrangement (whether or not
            some other subsequent action or event would be required to cause
            such payment, increase, acceleration, or vesting to be triggered).

      (p)   As to any Westcoast Plan that is subject to Title IV of ERISA, no
            accumulated funding deficiency, whether or not waived, within the
            meaning of Section 302 of ERISA or Section 412 of the Code has been
            incurred, no reportable event within the meaning of Section 4043 of
            ERISA has occurred, no notice of intent to terminate the plan has
            been given under Section 4041 of ERISA, no proceeding has been
            instituted under Section 4042 of ERISA to terminate the plan, and no
            liability to the United States Pension Benefit Guaranty Corporation
            has been incurred.

      (q)   As to any Westcoast Plan which is subject to ERISA or the Code, no
            act, omission or transaction has occurred which would result in
            imposition on Westcoast or any subsidiary of Westcoast of (i) breach
            of fiduciary duty liability damages under Section 409 of ERISA, (ii)
            a civil penalty assessed pursuant to subsections (c), (i) or (l) of
            Section 502 of ERISA, or (iii) a tax imposed pursuant to Chapter 43
            of Subtitle D of the Code.

      (r)   Each trust funding a Westcoast Plan, which trust is intended to be
            exempt from United States federal income taxation pursuant to
            Section 501(c)(9) of the Code, satisfies the requirements of such
            section and has received a favourable determination

                  AMENDED AND RESTATED COMBINATION AGREEMENT
                                       28

            letter from the United States Internal Revenue Service regarding
            such exempt status and has not, since receipt of the most recent
            favourable determination letter, been amended or operated in a way
            which would adversely affect such exempt status.

            January 1, 1998 have complied, with all applicable Laws other than
            non-compliance which would not, individually or in the aggregate,
            have a Material Adverse Effect on Westcoast. No investigation or
            review by any Governmental Entity with respect to Westcoast, any of
            its subsidiaries, or the knowledge of Westcoast, its Partially Owned
            Entities, is pending or, to the knowledge of Westcoast, is
            threatened, nor has any Governmental Entity indicated in writing an
            intention to conduct the same, other than those the outcome of which
            would not have a Material Adverse Effect on Westcoast.

      (b)   Westcoast and its subsidiaries and, to the knowledge of Westcoast,
            its Partially Owned Entities are in possession of all franchises,
            grants, authorizations, licenses, permits, easements, variances,
            exemptions, consents, certificates, approvals and orders necessary

            their businesses as they are now being conducted (collectively, the
            "Westcoast Permits"), except where the failure to be in possession
            of such Westcoast Permits would not, individually or in the
            aggregate, have a Material Adverse Effect on Westcoast, and there is
            no action, proceeding or investigation pending or, to the knowledge
            of Westcoast, threatened regarding any of the Westcoast Permits
            which would have a Material Adverse Effect on Westcoast. None of
            Westcoast, any of its subsidiaries or, to the knowledge of
            Westcoast, any of its Partially Owned Entities is in conflict with,
            or in default or violation of any of the Westcoast Permits, except
            for any such conflicts, defaults or violations which would not,
            individually or in the aggregate, have a Material Adverse Effect on
            Westcoast.

      (c)   None of Westcoast, any of its subsidiaries or, to the knowledge of
            Westcoast, any directors, officers, agents or employees of Westcoast

            reasonably be expected to have a material and adverse effect on
            Westcoast.

                  AMENDED AND RESTATED COMBINATION AGREEMENT

3.16  Restrictions on Business Activities

      There is no agreement, judgment, injunction, order or decree binding upon
Westcoast or any of its subsidiaries that has or could be reasonably expected to
have the effect of prohibiting, restricting or materially impairing any business
practice of Westcoast or any of its subsidiaries, any acquisition of property by
Westcoast or any of its subsidiaries or the conduct of business by Westcoast or
any of its subsidiaries as currently conducted other than such agreements,
judgments, injunctions, orders or decrees which would not, individually or in
the aggregate, have a Material Adverse Effect on Westcoast.

3.17  Intellectual Property

      (a)   Westcoast and its subsidiaries, directly or indirectly, own, license
            or otherwise have legally enforceable rights to use, or can acquire
            on reasonable terms and without material expense, all patents,
            patent rights, trademarks, trade names, service marks, copyrights
            and any applications therefore, technology, know-how, computer
            software and applications and tangible or intangible proprietary

            business of Westcoast and its subsidiaries as presently conducted
            (the "Intellectual Property Rights").

      (b)   In the case of Intellectual Property Rights owned by Westcoast or
            one of its subsidiaries, either Westcoast or one of its subsidiaries
            owns such Intellectual Property Rights free and clear of any
            material liens, charges or encumbrances. Westcoast or one of its
            subsidiaries has an adequate right to the use of the Intellectual
            Property Rights or the material covered thereby in connection with
            the services or products in respect of which such Intellectual
            Property Rights are being used. Westcoast has not received any
            written notice or claim, nor has it received any other information,
            stating that the manufacture, sale, licensing, or use of any of the
            services or products of Westcoast or any of its subsidiaries as now

            written notice or claim, nor has it received any other information,
            stating that the use by Westcoast or any of its subsidiaries of any
            trademarks, service marks, trade names, trade secrets, copyrights,

            written notice or claim, nor has it received any other information,
            challenging the ownership by Westcoast or any of its subsidiaries or
            the validity of any of the Intellectual Property Rights. All
            registered patents, trademarks, service marks and copyright held by
            Westcoast and its subsidiaries are subsisting, except to the extent
            any failure to be subsisting would not have a Material Adverse
            Effect on Westcoast. To the knowledge of Westcoast, there is no
            material unauthorized use, infringement or

                  AMENDED AND RESTATED COMBINATION AGREEMENT
                                       30

            misappropriation of any of the Intellectual Property Rights by any
            third party, including any employee or former employee of Westcoast
            or any of its subsidiaries No Intellectual Property Right is subject
            to any known outstanding decree, order, judgment, or stipulation
            restricting in any manner the licensing thereof by Westcoast or any
            of its subsidiaries, except to the extent any such restriction would
            not have a Material Adverse Effect on Westcoast.

3.18  Insurance

      Each of Westcoast and its subsidiaries is, and has been continuously since
September 1, 1996, insured by reputable and financially responsible insurers in
amounts and against risks and losses as are customary for companies conducting
their respective businesses. Westcoast's and its subsidiaries' insurance
policies are in all material respects in full force and effect in accordance
with their terms, no notice of cancellation or termination has been received,
and there is no existing default or event which, with the giving of notice or
lapse of time or both would constitute a default thereunder.

3.19  Property

      (a)   Westcoast, its subsidiaries and, to the knowledge of Westcoast, its
            Partially Owned Entities have defensible title (or, with respect to
            pipelines, equipment and other tangible personal property used in
            connection with Westcoast's pipeline operations (collectively,
            "Westcoast Pipeline Assets") title to or interest in the applicable
            Westcoast Pipeline Assets sufficient to enable Westcoast, its
            subsidiaries and, to the knowledge of Westcoast, its Partially Owned
            Entities to conduct their businesses with respect thereto without
            material interference as it is currently being conducted) to all
            their material properties and assets, whether tangible or
            intangible, real, personal or mixed, free and clear of all liens,
            except for liens disclosed in the Westcoast Documents and liens the
            existence of which would not have a Material Adverse Effect on
            Westcoast.

      (b)   The businesses of Westcoast and each of its subsidiaries have been
            and are being operated in a manner which does not violate (in any
            manner which would, or which would be reasonably expected to, have a
            Material Adverse Effect on Westcoast) the terms of any easements,
            rights of way, permits, servitudes, licenses, leasehold estates and
            similar rights relating to real property (collectively, "Easements")
            used by Westcoast and each of its subsidiaries in such businesses.
            All Easements are valid and enforceable, except as the
            enforceability thereof may be affected by bankruptcy, insolvency or
            other Laws of general applicability affecting the rights of
            creditors generally or principles of equity, and grant the rights
            purported to be granted thereby and all rights necessary thereunder
            for the current operation of such businesses where the failure of
            any such Easement to be valid and enforceable or to grant the rights
            purported to be granted thereby or necessary thereunder would have a
            Material Adverse Effect on Westcoast. There are no special gaps in
            the Easements which would impair the conduct of such businesses in a
            manner that would, or that would be reasonably expected to, have a
            Material Adverse Effect on Westcoast, and no part of the Westcoast
            Pipeline Assets is located on property which is not owned in fee by

                  AMENDED AND RESTATED COMBINATION AGREEMENT

            Westcoast or a subsidiary of Westcoast or subject to an Easement in
            favour of Westcoast or a subsidiary of Westcoast, where the failure
            of such Westcoast Pipeline Assets to be so located would have a
            Material Adverse Effect on Westcoast.

3.20  Regulatory Proceedings

      None of Westcoast, any of its subsidiaries or, to the knowledge of
Westcoast, any of its Partially Owned Entities, all or part of whose rates or
services are regulated by a Governmental Entity, is a party to any proceeding
before a Governmental Entity which is reasonably likely to result in orders
having a material burden on the future operations or business of Westcoast or
any Material Subsidiary of Westcoast nor has written notice of any such
proceeding been received by Westcoast, any of its subsidiaries or, to the
knowledge of Westcoast, any of its Partially Owned Entities.

3.21  Regulation as a Utility

      (a)   Westcoast and all of its "subsidiary companies" and "affiliates", as
            such terms are defined in the 1935 Act, either are not subject to or
            are exempt from all provisions of the 1935 Act other than Section
            9(a)(2) of the 1935 Act.

      (b)   None of Westcoast or any of its "subsidiary companies" or
            "affiliates" is subject to regulation as a "holding company" or a
            "subsidiary company" or "affiliate" of a "holding company", as such
            terms are defined in the 1935 Act.

3.22  Futures Trading and Fixed Price Exposure

      The Board of Directors of Westcoast has approved the formation and mandate
of the Corporate Risk Management Committee (the "CRMC"). The CRMC is responsible
for providing the overall direction on all aspects of Westcoast's business risk
management. Such responsibilities include approval and oversight of the
aggregate risk limits and the delegation of risk management authority and
accountability to the business units and functional units. The business risk
management programs of Westcoast and its subsidiaries are consistent with the
policies of the CRMC.

      The Board of Directors of Westcoast has established risk parameters to
restrict the level of risk that Engage Energy Canada, Inc. ("Engage") and its
subsidiaries are authorized to take with respect to the net position of Engage
and its subsidiaries resulting from all physical commodity transactions,
exchange traded futures and options and over-the-counter derivative instruments
(the "Net Engage Position") and the CRMC monitors the compliance by Engage and
its subsidiaries with such risk parameters. The risk parameters established by
the Board of Directors of Westcoast as of the date hereof are set forth in
Section 3.22 of the Westcoast Disclosure Letter and may be modified only by the
Board of Directors of Westcoast. The Net Engage Position is within the risk
parameters which have been established by Westcoast's Board of Directors or
otherwise approved by Westcoast's Board of Directors.

      In the case of Westcoast's regulated subsidiaries, risk management
programs have been established which govern the actions and conduct of such
subsidiaries with respect to their management of gas supply portfolio risk
arising from the use of physical commodity

transactions, exchange traded futures and options and over-the-counter
derivative instruments. The actions of each regulated subsidiary are reviewed by
each of such subsidiary's respective regulatory bodies. Such subsidiaries are in
compliance with their stated programs or policies.

3.23  Opinion of Financial Advisors

      The Board of Directors of Westcoast has received the opinions of Credit
Suisse First Boston Corporation and CIBC World Markets Inc., Westcoast's
financial advisors, to the effect that, as of the date hereof, the consideration
to be received by the holders of Westcoast Common Shares pursuant to the
transactions contemplated hereby is fair to the holders of Westcoast Common
Shares from a financial point of view and those opinions have not been
withdrawn, reserved or modified in any material respect.

3.24  Brokerage and Finders' Fees

      Except for Westcoast's obligations to Credit Suisse First Boston
Corporation and CIBC World Markets Inc., neither Westcoast nor any subsidiary of
Westcoast or any shareholder, director, officer or employee thereof, has
incurred or will incur on behalf of Westcoast, any brokerage, finders' or
similar fee in connection with the transactions contemplated hereby. Copies of
all written agreements relating to Westcoast's obligations to Credit Suisse
First Boston Corporation and CIBC World Markets Inc. have previously been
provided to Duke Energy and all other agreements relating to such obligations
are described in Section 3.24 of the Westcoast Disclosure Letter.

3.25  Westcoast Rights Plan

      None of the execution or the delivery of this Agreement or the taking of
any action contemplated by this Agreement results, or will result, in Duke
Energy becoming an Acquiring Person (as defined in the Westcoast Rights Plan),
provided that, prior to the consummation of the Arrangement, the Westcoast
Rights Plan Waiver Resolution is approved by the affirmative vote of a majority
of the votes cast by holders of Westcoast Common Shares.

3.26  Solvency of Westcoast

      Westcoast is not insolvent, and at the time of the consummation of the
Arrangement will not be insolvent, as defined in Section 192(2) of the CBCA.

                                   ARTICLE 4

            REPRESENTATIONS AND WARRANTIES OF THE DUKE ENERGY PARTIES

      The Duke Energy Parties represent and warrant to Westcoast as follows in
each case except as set forth in the Duke Energy Disclosure Letter (each of
which exceptions shall specifically identify the relevant section hereof to
which it relates):

                  AMENDED AND RESTATED COMBINATION AGREEMENT
                                       33
<PAGE>

4.1   Organization and Standing

      (a)   Each of the Duke Energy Parties has been duly organized or formed
            and is validly existing under the Laws of its jurisdiction of
            organization or formation with full corporate or legal power and
            authority to own, lease and operate its properties and to conduct
            its businesses as currently owned and conducted except where,
            individually or in the aggregate, the failure of a subsidiary other
            than a Material Subsidiary to be so organized, formed or existing or
            to have such power or authority would not have a Material Adverse
            Effect on Duke Energy. Each of the Duke Energy Parties is duly
            qualified to do business in each jurisdiction in which the nature of
            the business conducted by it or the ownership or leasing of its
            properties requires it to so qualify, except where the failure to be
            so qualified would not have a Material Adverse Effect on Duke
            Energy.

      (b)   Duke Energy has heretofore made available to Westcoast complete and
            correct copies of its governing documents as well as the governing
            documents of Exchangeco, in each case as in effect on the date
            hereof.

4.2   Capitalization

      (a)   The authorized capital stock of Duke Energy consists of 12.5 million
            shares of Preferred Stock, 10.0 million shares of Preferred Stock A,
            1.5 million shares of Preference Stock and 2.0 billion Duke Energy
            Common Shares and there were 2,284,984 shares of Preferred Stock,
            2,057,185 shares of Preferred Stock A and no Preference Stock issued
            and outstanding and 775,386,163 Duke Energy Common Shares issued and
            outstanding as of September 6, 2001. As of September 6, 2001 there
            were 55,276,119 Duke Energy Common Shares reserved, in the
            aggregate, for issuance in respect of the Duke Energy Stock Plans.
            As of August 31, 2001, there were outstanding options permitting the
            holders thereof to purchase 20,166,929 Duke Energy Common Shares in
            the aggregate.

      (b)   All of the outstanding shares of capital stock of the Duke Energy
            Parties have been duly authorized and are validly issued and fully
            paid and non-assessable, were not issued in violation of pre-emptive
            or similar rights or any other agreement or understanding binding
            upon the Duke Energy Parties and were issued in compliance with all
            applicable securities Laws and the governing documents of the Duke
            Energy Parties except where, individually or in the aggregate, the
            failure of the shares or ownership interest in a subsidiary other
            than a Material Subsidiary to be so authorized or issued would not
            have a Material Adverse Effect on Duke Energy. The authorized
            capital stock of Exchangeco consists of an unlimited number of
            common shares and an unlimited number of preference shares. As of
            the date hereof, all of the outstanding capital stock of Exchangeco
            is owned by N.S. U.L.C. and all of the outstanding capital stock of
            N.S. U.L.C. is owned indirectly by Duke Energy.

      (c)   Except as described in Section 4.2(a) above, there are no
            outstanding options, warrants, subscriptions, puts, calls or other
            rights, agreements, arrangements or commitments (pre-emptive,
            contingent or otherwise) obligating Duke Energy to offer,

            issue, sell, redeem, repurchase, otherwise acquire or transfer,
            pledge or encumber any capital stock of Duke Energy nor are there
            outstanding any securities or obligations of any kind convertible
            into or exercisable or exchangeable for any capital stock of Duke
            Energy and Duke Energy has no obligation of any kind to issue any
            additional securities or to pay for or repurchase any securities.
            There are not outstanding as of the date hereof any stock
            appreciation rights, phantom equity or similar rights, agreements,
            arrangements or commitments based upon the book value, income or any
            other attribute of Duke Energy or any of its subsidiaries. There are
            no outstanding bonds, debentures or other evidences of indebtedness
            of Duke Energy or any of its subsidiaries having the right to vote
            (or that are exchangeable or convertible for or exercisable into
            securities having the right to vote) with the holders of the Duke
            Energy Common Shares on any matter as of the date hereof.

4.3   Authority and No Conflicts

      (a)   Each of the Duke Energy Parties has all requisite corporate power
            and authority to enter into this Agreement and to perform its
            obligations hereunder and to consummate the transactions
            contemplated hereby. The execution and delivery of this Agreement by
            the Duke Energy Parties and the consummation by the Duke Energy
            Parties of the transactions contemplated by this Agreement have been
            duly and validly authorized by all requisite corporate action and no
            other corporate proceedings on the part of the Duke Energy Parties
            are necessary to authorize this Agreement or to consummate the
            transactions contemplated hereby.

      (b)   This Agreement has been duly executed and delivered by the Duke
            Energy Parties and constitutes a legal, valid and binding obligation
            of each of the Duke Energy Parties, enforceable against each of them
            in accordance with its terms, except as the same may be limited by
            bankruptcy, insolvency and other applicable Laws affecting
            creditors' rights generally, and by general principles of equity.

      (c)   The Board of Directors of Duke Energy at a meeting duly called and
            held has determined by the unanimous approval of all directors
            voting that this Agreement and the transactions contemplated hereby
            are in the best interests of Duke Energy and the holders of Duke
            Energy Common Shares.

      (d)   Neither the execution and delivery of this Agreement by the Duke
            Energy Parties nor the performance by each of them of their
            obligations hereunder and the completion of the transactions
            contemplated hereby, will:

            (i)   conflict with, or violate any provision of, the governing
                  documents of any of the Duke Energy Parties;

            (ii)  subject to the consents, approvals, orders, authorizations,

                  registrations, declarations or filings referred to in Section
                  4.4 being made or obtained, violate or

                  conflict with or result in the breach of, or constitute a
                  default (or an event that with the giving of notice, the
                  passage of time, or both would constitute a default) under, or
                  entitle any party (with the giving of notice, the passage of
                  time or both) to terminate, accelerate, modify or call any
                  obligations or rights under any credit agreement, note, bond,
                  mortgage, indenture, deed of trust, contract, agreement,
                  lease, license, franchise, permit, concession, easement or
                  other instrument to which Duke Energy or any of its
                  subsidiaries is a party or by which Duke Energy or any of its
                  subsidiaries or its or their property is bound or subject; or

            (iv)  result in the imposition of any encumbrance, charge or lien
                  upon any of Duke Energy's assets or the assets of any of its
                  subsidiaries, or restrict, hinder, impair or limit the ability
                  of Duke Energy or any of its subsidiaries to carry on the
                  business of Duke Energy or any of its subsidiaries as and
                  where it is now being carried on;

      except in the case of clauses (ii) through (iv) for any of the foregoing
      that would not, individually or in the aggregate, have a Material Adverse
      Effect on Duke Energy or materially impair the ability of Duke Energy to
      perform its obligations hereunder or prevent or materially delay the
      consummation of any of the transactions contemplated hereby.

4.4   Consents; Approvals

      No consent, approval, order or authorization of, or registration,
declaration or filing with, any third party or Governmental Entity is required

respective governing documents, (b) any credit agreement, note, bond, mortgage,
indenture, contract, agreement, lease, license, franchise, permit, concession,

<PAGE>

subsidiaries or any of its or their property is bound or subject, except, in the
case of clause (b), defaults and violations which, individually or in the
aggregate, would not have a Material Adverse Effect on Duke Energy.

4.6   Absence of Certain Changes or Events

      Except as disclosed in the Duke Energy SEC Documents filed prior to the
date hereof, since December 31, 2000, there has been no Material Adverse Effect
with respect to Duke Energy or any event, occurrence or development which would

            1933 Act (the "Duke Energy SEC Documents"), (ii) any applicable
            state securities authority and (iii) any other Governmental Entity,
            except in each case where the failure to file any such forms,
            reports, schedules, statements or other documents would not have a
            Material Adverse Effect on Duke Energy (all such forms, reports,
            schedules, statements and other documents are collectively referred
            to as the "Duke Energy Documents"). The Duke Energy SEC Documents,
            at the time filed (x) did not contain any untrue statement of a
            material fact or omit to state a material fact required to be stated
            therein or necessary in order to make the statements contained
            therein not misleading in light of the circumstances under which
            they were made and (y) complied in all material respects with the
            requirements of applicable Laws (including the 1933 Act, the
            Exchange Act and the rules and regulations thereunder).

      (b)   The consolidated financial statements (including in each case, any
            related notes thereto) contained in any Duke Energy SEC Documents
            (i) have been prepared in accordance with United States generally
            accepted accounting principles applied on a consistent basis during
            the periods involved (subject, in the case of unaudited financial
            statements, to the absence of notes), (ii) complied in all material
            respects with the requirements of applicable securities Laws, and
            (iii) fairly present, in all material respects, the consolidated
            financial position, results of operations and cash flows of Duke
            Energy and its subsidiaries as of the respective dates thereof and
            for the respective periods covered thereby, subject, in the case of
            unaudited financial statements, to normal, recurring audit
            adjustments none of which will be material.

      (c)   From January 1, 1998 to the date of this Agreement, there has been
            no change in Duke Energy's accounting policies or methods of making
            accounting estimates or changes in estimates that are material to
            such financial statements, except as described in the notes thereto
            with respect to periods ending prior to the date hereof.

      There are no claims, actions, proceedings or investigations pending or, to
the knowledge of Duke Energy, threatened against Duke Energy or any of its
subsidiaries before any Governmental Entity (and Duke Energy and its
subsidiaries have no knowledge of any facts that are likely to give rise to any
such claim, action, proceeding or investigation) that would be reasonably
expected to have a Material Adverse Effect on Duke Energy, or prevent or
materially delay consummation of the transactions contemplated by this
Agreement. Neither Duke Energy nor any of its subsidiaries, nor their respective
assets and properties, is subject to any outstanding judgment, order, writ,
injunction or decree that has had or would be reasonably expected to have a
Material Adverse Effect on Duke Energy or that would prevent or materially delay
consummation of the transactions contemplated by this Agreement.

4.9   Environmental

      Except for any matters which individually or in the aggregate are not
reasonably likely to result in a Material Adverse Effect on Duke Energy:

            conducted, and are now, in compliance with all Environmental Laws;

      (b)   Duke Energy and its subsidiaries are in possession of, and in

            Laws to own, lease and operate their properties and to conduct their
            respective businesses as they are now being conducted or as proposed
            to be conducted (collectively the "Duke Energy Environmental
            Permits"); and

      (c)   neither Duke Energy nor any of its subsidiaries is subject to:

            (i)   any Environmental Laws that require any work, repairs,
                  construction, change in business practices or operations, or
                  expenditures, including capital expenditures for facility
                  upgrades, environmental investigation and remediation
                  expenditures, or any other such expenditures;

            (ii)  any written demand or written notice alleging the breach of or
                  with respect to liability under any Environmental Laws
                  applicable to Duke Energy or any subsidiary of Duke Energy,
                  including any regulations respecting the use, storage,
                  treatment, transportation or disposition (including disposal
                  or arranging for disposal) of Hazardous Substances;

            (iii) any written demand or written notice with respect to
                  liability, by contract or operation of Environmental Laws
                  applicable to Duke Energy or any current or former subsidiary
                  of Duke Energy or any of their respective predecessor
                  entities, divisions or any formerly owned, leased or operated
                  properties or assets of the foregoing, including liability
                  with respect to the presence, release, threatened release or
                  discharge of Hazardous Substances; or

                  AMENDED AND RESTATED COMBINATION AGREEMENT
                                       38
<PAGE>

            (iv)  any changes in the terms or conditions of any Duke Energy
                  Environmental Permits or any renewal (other than renewals in
                  the ordinary course on the expiry of permits), modification,
                  revocation, reissuance, alteration or amendment of such Duke
                  Energy Environmental Permits that are required in connection
                  with the execution or delivery of this Agreement, the
                  consummation of the transactions contemplated hereby or the
                  continuation of business of Duke Energy or any subsidiaries of
                  Duke Energy following such consummation.

4.10  Nuclear Operations

      To the knowledge of Duke Energy, the operations of its Nuclear Steam
Generating Stations ("Nuclear Stations") are and have at all times been
conducted in material compliance with applicable health, safety, regulatory and
other legal requirements. To the knowledge of Duke Energy, the Nuclear Stations
maintain emergency plans designed to respond to an unplanned release therefrom
of radioactive materials into the environment, liability insurance to the extent
required by Law, and such further insurance (other than liability insurance) as
is consistent with Duke Energy's view of the risks inherent in the operation of
a nuclear power facility. To the knowledge of Duke Energy, plans for the
decommissioning of each of the Nuclear Stations and for the short-term storage
of spent nuclear fuel conform in all material respects with applicable
regulatory or other legal requirements, and such plans have at all times since
January 1, 1998 been funded to the extent required by Law (which funded amount
is not materially inconsistent, in the aggregate, with Duke Energy's budget
projections for the amount required to be spent under such plans) except for any

4.11  Compliance with Laws; Permits

      (a)   Duke Energy and its subsidiaries are in compliance, and at all times
            since January 1, 1998 have complied, with all applicable Laws other
            than non-compliance which would not, individually or in the
            aggregate, have a Material Adverse Effect on Duke Energy. No
            investigation or review by any Governmental Entity with respect to
            Duke Energy or any of its subsidiaries is pending or, to the
            knowledge of Duke Energy, is threatened, nor has any Governmental
            Entity indicated in writing an intention to conduct the same, other
            than those the outcome of which would not have a Material Adverse
            Effect on Duke Energy.

      (b)   Duke Energy and its subsidiaries are in possession of all
            franchises, grants, authorizations, licenses, permits, easements,
            variances, exemptions, consents, certificates, approvals and orders
            necessary to own, lease and operate their properties and to lawfully
            carry on their businesses as they are now being conducted
            (collectively, the "Duke Energy Permits"), except where the failure
            to be in possession of such Duke Energy Permits would not,
            individually or in the aggregate, have a Material Adverse Effect on
            Duke Energy, and there is no action, proceeding or investigation
            pending or, to the knowledge of Duke Energy, threatened regarding
            any of the Duke Energy Permits which would have a Material Adverse
            Effect on Duke Energy. Neither Duke Energy nor any of its
            subsidiaries is in conflict with, or in default or violation of any
            of the Duke Energy Permits, except for any such conflicts,

            defaults or violations which, individually or in the aggregate,
            would not have a Material Adverse Effect on Duke Energy.

      (c)   None of Duke Energy, any of its subsidiaries or, to the knowledge of
            Duke Energy, any directors, officers, agents or employees of Duke
            Energy or any of its subsidiaries has (i) used any funds for
            unlawful contributions, gifts, entertainment or other unlawful
            expenses relating to political activity, or (ii) made any unlawful
            payment to any government officials or employees or to political
            parties or campaigns or violated any provision of the United States
            Foreign Corrupt Practices Act of 1977, as amended in each case which
            could reasonably be expected to have a material and adverse effect
            on Duke Energy.

4.12  Regulatory Proceedings

      Neither Duke Energy nor any of its subsidiaries, all or part of whose
rates or services are regulated by a Governmental Entity, is a party to any
proceeding before a Governmental Entity which is reasonably likely to result in
orders having a material burden on the future operations or business of any
Material Subsidiary of Duke Energy nor has written notice of any such proceeding
been received by Duke Energy or any of its subsidiaries.

4.13  Futures Trading and Fixed Price Exposure

      The Market Risk Committee of Duke Energy has established risk parameters
to restrict the level of risk that Duke Energy and its subsidiaries are
authorized to take with respect to the open position resulting from all physical
commodity transactions, exchange traded futures and options and over-the-counter
derivative instruments (the "Open Duke Energy Position") and monitors the
compliance by Duke Energy and its subsidiaries with such risk parameters. The
risk parameters established by the Market Risk Committee of Duke Energy may be
modified only by the Market Risk Committee of Duke Energy. The Open Duke Energy
Position is within the risk parameters which have been established by the Market
Risk Committee of Duke Energy.

employees has incurred or will incur on behalf of Duke Energy, any brokerage,
finders' or similar fee in connection with the transactions contemplated hereby,

advisor pursuant to a written agreement.

                  material respect any contract, agreement, guarantee, lease
                  commitment or arrangement of the nature required to be
                  disclosed by Section 3.9 or any contract which involves

                  by Westcoast's or such subsidiary's regular independent
                  accountants, as the case may be.

           (xiii) Westcoast shall not, nor shall it permit any of its
                  subsidiaries to, engage in any activities which would cause a
                  change in its status, or that of its subsidiaries, under the
                  1935 Act, or that would impair the ability of Duke Energy to
                  continue to claim an exemption as of right under Rule 2 of the
                  1935 Act following the Arrangement.

            (xiv) Westcoast shall not, nor shall it permit any of its
                  subsidiaries to, make or rescind any material tax election.

            (xv)  Westcoast shall not take any action to exempt from, waive or
                  make not subject to (including redemption of outstanding
                  rights) (A) the Westcoast Rights Plan or (B) any takeover Law
                  or other Law that purports to limit or restrict business
                  combinations or the ability to acquire or vote shares, any
                  person (other than Duke Energy and its subsidiaries) or any
                  action taken thereby, including any Take-over Bid (as defined
                  in the Westcoast Rights Plan), which person or action would
                  have otherwise been subject to the restrictive provisions
                  thereof and not exempt therefrom. Westcoast shall not nor
                  shall it permit any subsidiary to, (a) enter into any
                  confidentiality or standstill agreement except as permitted by
                  Section 5.5(a), (b) amend, release any third party from its
                  obligations or grant any consent under any confidentiality or
                  standstill provision or fail to fully enforce any such
                  provision.

            (xvi) Westcoast shall not, nor shall it permit any of its
                  subsidiaries to, take or fail to take any action which would
                  cause any of Westcoast's representations or

                  warranties hereunder to be untrue or would be reasonably
                  expected to prevent or materially impede, interfere with or
                  delay the Arrangement.

           (xvii) Westcoast shall not consent to a holder of Westcoast Common
                  Shares withdrawing or abandoning his or her dissent pursuant
                  to the Dissent Rights or provide notice to the Court under the
                  Final Order that the Appropriate Regulatory Approvals have
                  been obtained, in either case without the prior written
                  consent of Duke Energy.

          (xviii) Westcoast shall not, nor shall it permit any of its
                  subsidiaries to, agree in writing or otherwise to take any of
                  the actions as described above in clauses (ii) through (xvi).

      (b)   Westcoast shall promptly advise Duke Energy in writing:

            (i)   of any event, condition or circumstance that might be
                  reasonably expected to cause any representation or warranty of
                  Westcoast contained in this Agreement to be untrue or
                  inaccurate on the Effective Date (or, in the case of any
                  representation or warranty made as of a specified date, as of
                  such specified date);

            (ii)  of any Material Adverse Effect on Westcoast or any event,
                  occurrence or development which would be reasonably expected
                  to have a Material Adverse Effect on Westcoast; and

            (iii) of any material breach by Westcoast of any covenant,
                  obligation or agreement contained in this Agreement.

      (c)   Westcoast shall use its reasonable best efforts to, and shall use
            its reasonable best efforts to cause its subsidiaries to, perform
            all obligations required to be performed by Westcoast or any of its
            subsidiaries under this Agreement, cooperate with Duke Energy in
            connection therewith, and do all such other acts and things as may
            be necessary or desirable in order to consummate and make effective,

            this Agreement and, without limiting the generality of the

                  Rights Plan Waiver Resolution (in a commercially reasonable
                  manner) and use reasonable best efforts to obtain the approval
                  by Westcoast Securityholders of the Arrangement and of the
                  Westcoast Rights Plan Waiver Resolution;

            (ii)  subject to the last sentence of Section 5.6(a), not adjourn,
                  postpone or cancel (or propose adjournment, postponement or
                  cancellation of) the Westcoast Meeting without Duke Energy's
                  prior written consent except as required by Laws or, in the
                  case of adjournment, as may be required by Westcoast
                  Securityholders as expressed by majority resolution;

                  so, to keep Duke Energy reasonably informed as to the status
                  of the proceedings related to obtaining the Appropriate
                  Regulatory Approvals, including, but not limited to, providing
                  Duke Energy the opportunity to be present for all
                  communications with any Governmental Entity and providing Duke
                  Energy with copies of all related applications and

                  the transactions contemplated hereby;

           (viii) use reasonable best efforts to have lifted or rescinded any

                  subsidiary of Westcoast to consummate the transactions
                  contemplated hereby which the failure to obtain would

                  hereby; and

            (xii) use reasonable best efforts to ensure that Westcoast's

      (d)   The Board of Directors of Westcoast shall recommend to the Westcoast
            Securityholders the approval of the Arrangement Resolution and the
            Westcoast Rights Plan Waiver Resolution; provided that the Board of
            Directors of Westcoast may withdraw, modify or change its
            recommendation if prior to the approval of the Arrangement by the
            Westcoast Securityholders, Westcoast receives a Superior Proposal
            that was not solicited or encouraged in violation of Section 5.5 and
            the Board of Directors of Westcoast determines in good faith (based
            upon the written opinion of its outside legal counsel) that it is
            necessary for the Board of Directors of Westcoast to take such
            action in order to discharge properly its fiduciary duties. Any such
            withdrawal, change or modification of the Westcoast Board of
            Directors' recommendation of the Arrangement and the Westcoast
            Rights Plan Waiver Resolution shall not change the approval of the
            Board of Directors of Westcoast for any purpose or change the
            obligation of Westcoast to present the Arrangement Resolution and
            the Westcoast Rights Plan Waiver Resolution (without recommendation)
            at a duly called and convened Westcoast Meeting in accordance with
            Westcoast's obligations under this Agreement.

      (e)   Westcoast shall not waive the application of Section 3.1 of the
            Westcoast Rights Plan to an Acquisition Proposal unless the
            Acquisition Proposal is a Superior Proposal and Westcoast has
            complied with Section 5.5 and Section 5.6, provided that, in such
            case, the waiver cannot be effective until after the Westcoast
            Meeting and further provided that such waiver cannot be effective if
            the Arrangement Resolution shall have been approved by the requisite
            majority of the Westcoast Securityholders at the Westcoast Meeting.

      (f)   Prior to the Effective Time, Westcoast will complete the corporate
            reorganizations as set forth in Section 5.1(f) of the Westcoast
            Disclosure Letter, subject only to (i) receipt of any required
            approval of any provincial regulatory body with respect to any
            portion of such reorganization which Westcoast shall use its
            reasonable best efforts to obtain, (ii) receipt of any required
            approvals under Westcoast's existing debt trust indentures and (iii)
            approval by Duke Energy of the costs to be incurred to complete such
            reorganization.

                  Income Tax Act (Canada) for holders who are otherwise eligible
                  for such treatment.

      (b)   Duke Energy shall promptly advise Westcoast in writing:

            (i)   of any event, condition or circumstance that might be
                  reasonably expected to cause any representation or warranty of
                  the Duke Energy Parties contained in this Agreement to be
                  untrue or inaccurate on the Effective Date (or, in the case of
                  any representation or warranty made as of a specified date, as
                  of such specified date);

            (ii)  of any Material Adverse Effect on Duke Energy or any event,
                  occurrence or development which would be reasonably expected
                  to have a Material Adverse Effect on Duke Energy; and

            (iii) of any material breach by any of the Duke Energy Parties of
                  any of their covenants, obligations or agreements contained in
                  this Agreement.

      (c)   Duke Energy shall use its reasonable best efforts to, and shall use
            its reasonable best efforts to cause its subsidiaries to, perform
            all obligations required to be performed by it or any of its
            subsidiaries under this Agreement, cooperate with Westcoast in

            this Agreement and, without limiting the generality of the
            foregoing:

            (i)   use reasonable best efforts to satisfy or cause to be
                  satisfied as soon as reasonably practicable all conditions
                  precedent that are set forth in Article 6 hereof;

            (ii)  apply for and use reasonable best efforts to obtain promptly
                  all Appropriate Regulatory Approvals relating to Duke Energy

                  Westcoast reasonably informed as to the status of the
                  proceedings related to obtaining the Appropriate Regulatory
                  Approvals, including, but not limited to, providing Westcoast

            as to its management personnel; provided that such access shall be
            provided on a basis that minimizes the disruption to the operations

            the termination of this Agreement, to such of Duke Energy's
            management personnel as Westcoast may request, acting reasonably.

      (b)   The Duke Energy Parties and Westcoast acknowledge that certain
            information received pursuant to Section 5.3(a) will be non-public
            or proprietary in nature and as such will be deemed to be
            "Confidential Information" for purposes of the Confidentiality
            Agreement. The Duke Energy Parties and Westcoast further acknowledge
            their obligation to maintain the confidentiality of such
            Confidential Information in accordance with the Confidentiality
            Agreement.

5.4   Indemnification

      (a)   Duke Energy agrees that all rights to indemnification for acts or
            omissions occurring prior to the Effective Time existing as of the
            date hereof in favour of the directors or officers of Westcoast as
            provided in its governing documents or in written contracts in
            effect on the date hereof, shall survive the Arrangement and shall
            continue in full force and effect until the earlier of the
            expiration of the applicable statute of limitations with respect to
            any claims against directors or officers of Westcoast arising out of
            such acts or omissions and the sixth anniversary of the Effective
            Date, and Duke Energy hereby assumes, effective upon consummation of
            the Arrangement, all such liability with respect to any matters
            arising prior to the Effective Time.

      (b)   Duke Energy shall use reasonable best efforts to cause to be
            maintained in effect, for not less than six years from the Effective
            Time, policies of directors' and officers' liability insurance that
            provide substantially the same coverage and contain substantially
            similar terms and conditions for acts and omissions prior to the
            Effective Time as is provided under or contained in the policies of
            the directors' and officers' liability insurance maintained by
            Westcoast as of the date of this Agreement so long as the annual
            premium therefor would not be in excess of 200% of the last annual
            premium paid prior to the date hereof.

5.5   Covenants Regarding Non-Solicitation

      (a)   Westcoast shall immediately cease and cause to be terminated any
            existing solicitation, encouragement, activity, discussion or
            negotiation with any parties by Westcoast, any of its subsidiaries
            or any of its or its subsidiaries' officers, directors, employees,
            representatives and agents with respect to an Acquisition Proposal
            whether or not initiated by Westcoast and in connection therewith,
            Westcoast shall request (and exercise all rights it has to require)
            the return of information regarding Westcoast and its subsidiaries
            previously provided to such parties and shall request (and exercise
            all rights it has to require) the destruction of all materials
            including or incorporating any information regarding Westcoast and
            its subsidiaries.

      (b)   Subject to Section 5.6, Westcoast agrees that it shall not, and
            shall not authorize or permit any of its subsidiaries or any of its
            or its subsidiaries' officers, directors, employees, representatives
            or agents, directly or indirectly, to (i) solicit, initiate,
            encourage or knowingly facilitate, including by way of furnishing
            information or entering into any form of agreement, arrangement or
            understanding, any inquiries or the making of any proposals
            regarding an Acquisition Proposal, (ii) participate in any
            discussions or negotiations regarding any Acquisition Proposal,
            (iii) withdraw or modify in a manner adverse to Duke Energy the
            approval or recommendation of the Board of Directors of Westcoast of
            the transactions contemplated hereby, (iv) approve or recommend any
            Acquisition Proposal or (v) enter into any agreement, arrangement or
            understanding related to any Acquisition Proposal or requiring
            Westcoast to abandon, terminate or fail to consummate the
            Arrangement or providing for the payment of any break, termination
            or other fees or expenses to any person in the event that Westcoast
            or any of its subsidiaries completes the transactions contemplated
            hereby or any other transaction with Duke Energy or any of its
            affiliates agreed to prior to any termination of this Agreement.
            Notwithstanding the preceding sentence and any other provisions of
            this Agreement, the Board of Directors of Westcoast may, prior to
            the approval of the Arrangement by the Westcoast Securityholders,
            consider, participate in any discussions or negotiations with, or
            provide information in accordance with the last sentence of this
            paragraph to, any person who has delivered a bona fide written
            Acquisition Proposal which was not solicited or encouraged after the
            date of this Agreement and did not otherwise result from a breach of
            this Section 5.5 and that the Board of Directors of Westcoast
            determines in good faith, after consultation with its financial
            advisors and outside legal counsel, is a Superior Proposal;
            provided, however, that prior to taking any such action, (x) the
            Board of Directors of Westcoast must receive written advice of
            outside counsel that it is necessary for the Board of Directors of
            Westcoast to take such action in order to discharge properly its
            fiduciary duties and (y) Westcoast must obtain a confidentiality
            agreement from the person making such Acquisition Proposal that is
            substantively the same as the Confidentiality Agreement, including a
            standstill provision at least as stringent as contained in the
            Confidentiality Agreement; provided further that Westcoast shall not
            commence discussions or negotiations with, or provide information to
            any person who has delivered an unsolicited bona fide written
            Acquisition Proposal until 48 hours after Westcoast shall have
            advised Duke Energy of its determination that such Acquisition
            Proposal constitutes a Superior Proposal

                  AMENDED AND RESTATED COMBINATION AGREEMENT
                                       51
<PAGE>

            and of its intention to take such actions. Westcoast shall not
            consider, negotiate, accept, approve or recommend an Acquisition
            Proposal or provide information to any person proposing an
            Acquisition Proposal, in each case after the date of the approval of
            the Arrangement by the Westcoast Securityholders. If Westcoast
            receives a request for material non-public information from a person
            who has made an unsolicited bona fide written Acquisition Proposal
            and Westcoast is permitted, as contemplated under the second
            sentence of this Section 5.5(b), to negotiate the terms of such
            Acquisition Proposal, then, and only in such case, the Board of
            Directors of Westcoast may, subject to the execution by such person
            of the confidentiality agreement as described in (y) above, provide
            such person with access to information regarding Westcoast; provided
            that Westcoast sends a copy of any such confidentiality agreement to
            Duke Energy promptly upon its execution and Duke Energy is provided
            with a list of, and copies of, the information provided to such
            person and is immediately provided with access to similar
            information to which such person was provided.

      (c)   From and after the date of this Agreement, Westcoast shall promptly
            (and in any event within 24 hours) notify Duke Energy, at first
            orally and then in writing, of any inquiries, proposals or offers
            relating to or constituting an Acquisition Proposal, or any request
            for non-public information relating to Westcoast or any of its
            subsidiaries. Such notice shall include a description of the terms
            and conditions of any proposal, inquiry or offer, the identity of
            the person making such proposal, inquiry or offer and provide such
            other details of the proposal, inquiry or offer as Duke Energy may
            reasonably request. Westcoast shall keep Duke Energy fully informed
            on a prompt basis of the status, including any change to the
            material terms, of any such inquiry, proposal or offer.

      (d)   Westcoast shall ensure that its officers, directors and employees
            and its subsidiaries and their officers, directors and employees and
            any financial advisors or other advisors or representatives retained
            by it are aware of the provisions of this Section 5.5, and it shall
            be responsible for any breach of this Section 5.5 by such officers,
            directors, employees, financial advisors or other advisors or
            representatives.

5.6   Right to Accept a Superior Proposal

      (a)   If Westcoast has complied with Section 5.5 with respect thereto,
            Westcoast may accept, approve, recommend or enter into any
            agreement, understanding or arrangement in respect of a Superior
            Proposal prior to the approval of the Arrangement by the Westcoast
            Securityholders if, and only if (with the exception of a
            confidentiality agreement the execution of which shall not be
            subject to the conditions of this Section 5.6), (i) Westcoast has
            provided Duke Energy with a copy of the Superior Proposal document,
            (ii) five Business Days shall have elapsed from the later of (x) the
            date Duke Energy received written notice (a "Section 5.6 Notice")
            advising Duke Energy that Westcoast's Board of Directors has
            resolved, subject only to compliance with this Section 5.6, to
            accept, approve, recommend or enter into an agreement in respect of
            such Superior Proposal, specifying the terms and conditions of such
            Superior Proposal and identifying the person making such Superior
            Proposal,

                  AMENDED AND RESTATED COMBINATION AGREEMENT
                                       52
<PAGE>

            and (y) the date Duke Energy received a copy of such Superior
            Proposal, (iii) Westcoast's Board of Directors has determined in
            good faith (based upon the written opinion of its outside legal
            counsel) that it is necessary for the Board of Directors of
            Westcoast to take such action in order to discharge properly its
            fiduciary duties, (iv) such Superior Proposal does not provide for
            the payment of any break, termination or other fees or expenses to
            the other party in the event that Westcoast or any of its
            subsidiaries completes the transactions contemplated by this
            Agreement or any other transaction with Duke Energy or any of its
            affiliates agreed to prior to any termination of this Agreement, and
            (v) Westcoast has previously or concurrently will have paid to Duke
            Energy the Termination Fee, if any, payable under Section 7.3. In
            the event that Westcoast provides Duke Energy with a Section 5.6
            Notice on a date that is less than five Business Days prior to the
            Westcoast Meeting, Westcoast shall adjourn the Westcoast Meeting
            (without notice on the Arrangement or any related matters) to a date
            that is not less than five Business Days and not more than 10
            Business Days after the date of the Section 5.6 Notice.

      (b)   During the five Business Day period referred to in Section
            5.6(a)(ii), Westcoast agrees that Duke Energy shall have the right,
            but not the obligation, to offer to amend the terms of this
            Agreement. The Board of Directors of Westcoast will review any
            proposal by Duke Energy to amend the terms of this Agreement in good
            faith in order to determine, in its discretion in the exercise of
            its fiduciary duties, whether Duke Energy's amended proposal upon
            acceptance by Westcoast would result in such Superior Proposal
            ceasing to be a Superior Proposal. If the Board of Directors of
            Westcoast so determines, it will enter into an amended agreement
            with Duke Energy reflecting Duke Energy's amended proposal. If the
            Board of Directors of Westcoast continues to believe, in good faith
            and after consultation with financial advisors and outside counsel,
            that such Superior Proposal remains a Superior Proposal and
            therefore rejects Duke Energy's amended proposal, Westcoast may,
            subject to the terms of this Agreement, accept, approve, recommend
            or enter into an agreement, understanding or arrangement in respect
            of such Superior Proposal.

      (c)   Westcoast also acknowledges and agrees that each successive material
            modification of any Acquisition Proposal shall constitute a new
            Acquisition Proposal for purposes of Section 5.5 and the requirement
            under clause (ii) of Section 5.6(a) to initiate an additional five
            Business Day notice period.

5.7   Employee Benefits and Related Matters

      Duke Energy agrees, and after the Effective Time will cause Westcoast or
any of its subsidiaries, as the case may be, to:

      (a)   from the Effective Time through December 31, 2002, provide Affected
            Employees, taken as a whole, employee benefits pursuant to employee
            benefit plans, programs, policies or arrangements maintained by Duke
            Energy or any subsidiary of Duke Energy providing coverage and
            benefits which, in the aggregate, are no less favourable than (i)
            those provided to Affected Employees immediately prior to the
            Effective Time (other than benefits provided pursuant to Westcoast
            Employee Share

                  AMENDED AND RESTATED COMBINATION AGREEMENT
                                       53
<PAGE>

            Purchase Plans) or, (ii) if elected by Duke Energy with respect to
            all or certain Affected Employees, those provided from time to time
            after the Effective Time to employees of Duke Energy or its
            subsidiaries who are similarly situated, in terms of their
            positions, tenure and geographic locations, to such Affected
            Employees; "Affected Employees" means individuals who are actively
            employed by Westcoast or any of its subsidiaries as of the Effective
            Time, are not subject to a collective bargaining agreement and who
            remain employed with Duke Energy or any subsidiary of Duke Energy;

      (b)   give each Affected Employee full credit for purposes of determining
            severance pay and eligibility to participate, vesting and benefit
            accrual (except for purposes of benefit accrual under any defined
            benefit pension plans, or to the extent such treatment would result
            in duplicative accrual on or after the Effective Date of benefits
            for the same period maintained by Duke Energy or any subsidiary of
            Duke Energy), for such Affected Employee's service with Westcoast or
            any subsidiary of Westcoast to the same extent and for the same
            purpose recognized by Westcoast immediately prior to the Effective
            Time and previously disclosed to Duke Energy;

      (c)   waive all limitations as to preexisting conditions exclusions with
            respect to participation and coverage requirements applicable to the
            Affected Employees under any medical or dental benefit plans
            maintained by Duke Energy in which such employees may be eligible to
            participate, other than preexisting conditions exclusions imposed
            with respect to any Affected Employee immediately prior to such
            participation under any medical or dental plan maintained by
            Westcoast for the Affected Employees and other than preexisting
            conditions exclusions imposed by third-party health benefit
            providers; and

      (d)   provide that any co-payments and deductibles paid by Affected
            Employees under a welfare plan maintained by Westcoast during the
            plan year in which the coverage under a similar type of welfare plan
            maintained by Duke Energy begins shall be taken into account in
            satisfying any applicable deductible or out-of-pocket requirements
            under such Duke Energy welfare plan to the same extent such expenses
            are taken into account for the benefit of similarly situated
            employees of Duke Energy and its subsidiaries.

      Nothing herein shall be construed as (i) requiring Duke Energy to continue
the employment of any Affected Employee following the Effective Time, (ii)
limiting Duke Energy's ability to amend, modify or terminate any individual
employee benefit plan or arrangement of Westcoast, Duke Energy or any of their
respective subsidiaries, or (iii) requiring Duke Energy to maintain any
particular level of employee benefits for any individual employee following the
Effective Time subject to compliance with Section 5.7(a).

5.8   Prohibition on Voluntary Liquidation

      Duke Energy shall not, and shall cause its subsidiaries not to, take any
action relating to a voluntary liquidation, dissolution or winding-up of
Exchangeco, as the case may be, prior to the Redemption Date (as defined in the
Plan of Arrangement).

5.9   Conversion of Westcoast Preferred Shares

      (a)   On or prior to September 30, 2001, Westcoast shall deliver a
            conversion notice (specifying a 30-day notice period) to the holders
            of the outstanding Westcoast First Preferred Shares, Series 2
            regarding the conversion of such shares into Westcoast Common Shares
            in accordance with the terms of such First Preferred Shares, Series
            2. Westcoast shall complete such conversion by such time as is
            necessary to enable such holders to be holders entitled to receive
            notice of the Westcoast Meeting. Notwithstanding any other provision
            of this Agreement, the acts of Westcoast to convert the Westcoast
            First Preferred Shares, Series 2 in accordance with their terms and
            this Section 5.9 shall be deemed not to breach or violate or fail to
            satisfy any representations, warranties, covenants or obligations of
            Westcoast under this Agreement.

      (b)   Westcoast shall within two Business Days provide written notice to a
            designated officer of Duke Energy of any conversion notice given to
            Westcoast by a holder of First Preferred Shares, Series 5 (a "Series
            5 Conversion Notice") or any conversion notice given to Westcoast by
            a holder of UEI Holdings Inc. First Series Preferred Shares (a "UEI
            Conversion Notice"). Westcoast shall redeem, unless Duke Energy
            otherwise consents, all such First Preferred Shares, Series 5 in
            respect of which a Series 5 Conversion Notice is given, in
            accordance with the terms of such First Preferred Shares, Series 5
            and shall redeem, unless Duke Energy otherwise consents, all such
            UEI Holdings Inc. First Series Preferred Shares in respect of which
            a UEI Conversion Notice is given, in accordance with the terms of
            such UEI Holdings Inc. First Series Preferred Shares, as the case
            may be. Notwithstanding any other provision of this Agreement, the
            acts of Westcoast to redeem the First Preferred Shares, Series 5 and
            the UEI Holdings Inc. First Series Preferred Shares in accordance
            with their respective terms and this Section 5.9 shall be deemed not
            to breach or violate or fail to satisfy any representations,
            warranties, covenants or obligations of Westcoast under this
            Agreement.

            Arrangement, the failure to obtain which or the non-expiry of which
            would constitute a criminal offense, or would, individually or in

      This Agreement may be terminated and the Arrangement abandoned at any time
prior to the Effective Time (notwithstanding any approval of the Arrangement by
the Westcoast Securityholders):

      (a)   by the mutual written consent of Duke Energy and Westcoast (without
            further action on the part of the Westcoast Securityholders if
            terminated after the Westcoast Meeting);

      (b)   by either Westcoast or Duke Energy, if there shall be any Law that
            makes consummation of the Arrangement illegal or otherwise
            prohibited, or if any judgment, injunction, order or decree of a
            competent Governmental Entity (other than any order from the Court
            refusing to grant the Final Order) enjoining Duke Energy or
            Westcoast from consummating the Arrangement shall be entered and
            such judgment, injunction, order or decree shall have become final
            and non-appealable;

      (c)   by either Westcoast or Duke Energy, if the Effective Date does not
            occur on or prior to September 20, 2002; provided, however, that the
            right to terminate this Agreement under this Section 7.2(c) shall
            not be available to any party whose failure or whose affiliate's
            failure to perform any material covenant, agreement or obligation
            hereunder has been the cause of, or resulted in, the failure of the
            Effective Date to occur on or before such date;

      (d)   by Duke Energy if, (i) the Board of Directors of Westcoast fails to
            recommend or withdraws, modifies or changes its approval or
            recommendation of this Agreement, the Arrangement, the Arrangement
            Resolution or the Westcoast Rights Plan Waiver Resolution in a
            manner adverse to Duke Energy or recommends or approves a Superior
            Proposal, (ii) the Board of Directors of Westcoast fails to affirm
            its approval or recommendation of this Agreement, the Arrangement,
            the Arrangement Resolution or the Westcoast Rights Plan Waiver
            Resolution within 10 Business Days of any written request to do so
            from Duke Energy, (iii) the Arrangement Resolution and the Westcoast
            Rights Plan Waiver Resolution are not submitted for approval at the
            Westcoast Meeting, or the Westcoast Meeting is not held prior to
            January 31, 2002 or such later date to which the Westcoast Meeting
            shall have been adjourned or postponed as may be permitted pursuant
            to Section 5.6(a); provided that in the event a Force Majeure has
            occurred which makes giving notice of the Westcoast Meeting
            impractical, or if such notice has already been given, makes holding
            the Westcoast Meeting impractical on or prior to such date, such
            date shall be extended until the earlier of the thirty-fifth day
            after the cessation of such Force Majeure or March 31, 2002, or (iv)
            Westcoast shall have breached in any material respect its
            obligations under Section 5.5 or 5.6;

      (e)   (i) by either Westcoast or Duke Energy, if at the Westcoast Meeting,
            the requisite vote of Westcoast Securityholders to approve the
            Arrangement shall not be obtained or (ii) by either Westcoast or
            Duke Energy, if approval of the Court of the Final Order shall not
            be obtained, or (iii) by Duke Energy, if at the Westcoast Meeting,
            the

                  AMENDED AND RESTATED COMBINATION AGREEMENT
                                       60
<PAGE>

            requisite vote of holders of Westcoast Common Shares to approve the
            Westcoast Rights Plan Waiver Resolution shall not be obtained;

      (f)   by Duke Energy, if Westcoast has breached any of its
            representations, warranties, agreements or obligations herein which
            breach would result in the failure to satisfy one or more conditions
            set forth in Section 6.2(a) or Section 6.2(b) and such breach is not
            curable or if curable, is not cured within 30 days after notice
            thereof has been received by the party alleged to be in breach; or

      (g)   by Westcoast, if any of the Duke Energy Parties has breached any of
            its representations, warranties, agreements or obligations herein
            which breach would result in the failure to satisfy one or more
            conditions set forth in Section 6.3(a) or Section 6.3(b) and such
            breach is not curable or if curable, is not cured within 30 days
            after notice thereof has been received by the party alleged to be in
            breach.

7.3   Effect of Termination

      (a)   If this Agreement is terminated in accordance with the provisions of
            Section 7.2, no party shall have any further liability to perform
            its obligations hereunder except for the provisions of this Section
            7.3 and Section 5.3(b) and Section 8.9; provided that neither the
            termination of this Agreement nor anything contained in this Section
            7.3 shall relieve any party from any liability for any breach by it
            of this Agreement, including from any inaccuracy in its
            representations and warranties and any non-performance by it of its
            covenants and agreements made herein. If it shall be judicially
            determined that termination of this Agreement was caused by an
            intentional breach of this Agreement, then, in addition to any other
            remedies at law or equity for breach of this Agreement, the party so
            found to have intentionally breached this Agreement shall indemnify
            and hold harmless the other parties for their out-of-pocket costs,
            including fees and expenses of their counsel, accountants, financial
            advisors and other experts and advisors, incident to the
            negotiation, preparation and execution of this Agreement and related
            documentation.

      (b)   If this Agreement is terminated:

            (i)   by Duke Energy pursuant to Section 7.2(d); or

            (ii)  by either Party pursuant to Section 7.2(e)(i) or by Duke
                  Energy pursuant to Section 7.2(e)(iii) and at any time after
                  the date of this Agreement and prior to such termination a
                  bona fide Acquisition Proposal with respect to Westcoast or
                  its subsidiaries shall have been made, or any proposal or
                  expression of interest by a third party regarding an
                  Acquisition Proposal shall have been publicly disclosed;

                  then Westcoast will, in the case of a termination by Duke
                  Energy, within three Business Days following any such
                  termination or, in the case of a termination by Westcoast,
                  prior to such termination, pay to Duke Energy in cash by wire
                  transfer in immediately available funds to an account
                  designated by Duke Energy the Termination Fee.

      (c)   If this Agreement is terminated by either party pursuant to Section
            7.2(e)(i) or by Duke Energy pursuant to Section 7.2(e)(iii) and
            after the date of this Agreement and prior to such termination no
            bona fide Acquisition Proposal with respect to Westcoast or its
            subsidiaries shall have been made, and at such time no proposal or
            expression of interest by a third party regarding an Acquisition
            Proposal shall have been publicly disclosed and within 12 months
            after the date of such termination, Westcoast enters into any
            agreement for an Acquisition Proposal or consummates a transaction
            that constitutes an Acquisition Proposal, Westcoast will, prior to
            the earlier of consummation of a transaction that constitutes an
            Acquisition Proposal, or execution of a definitive agreement with
            respect thereto, pay to Duke Energy in cash by wire transfer in
            immediately available funds to an account designated by Duke Energy,
            the Termination Fee.

      (d)   If this Agreement is terminated by Duke Energy pursuant to Section
            7.2(f) and after the date of this Agreement and prior to such
            termination no bona fide Acquisition Proposal with respect to

            terminating party in cash by wire transfer in immediately available
            funds to an account designated by the terminating party an amount
            equal to the Expense Fee as payment in full of the terminating
            party's costs and expenses in connection with the transactions
            contemplated by this Agreement.

      (e)   If this Agreement is terminated by Duke Energy pursuant to Section
            7.2(f) and at any time after the date of this Agreement and prior to
            such termination a bona fide Acquisition Proposal with respect to
            Westcoast or its subsidiaries shall have been made, or any proposal
            or expression of interest by a third party regarding an Acquisition
            Proposal shall have been publicly disclosed, then (i) Westcoast

            consummation of a transaction that constitutes an Acquisition
            Proposal, or execution of a definitive agreement with respect
            thereto, pay to Duke Energy in cash by wire transfer in immediately

            Termination Fee minus the amount of any payment previously made
            pursuant to clause (i) of this subsection (e).

            the Termination Fee minus any payment previously made pursuant to
            Section 7.3(g).

      (g)   If this Agreement is terminated by either party pursuant to Section
            7.2(c) and at the date of such termination any required approval of
            any provincial regulatory body shall not have been obtained then
            Westcoast will, in the case of a termination by Duke Energy, within
            three Business Days following such termination or, in the case of a
            termination by Westcoast, prior to such termination, pay to Duke
            Energy in cash by wire transfer in immediately available funds to an
            account designated by Duke Energy an amount equal to the Expense Fee
            as payment in full of the Duke Energy Parties' costs and expenses in
            connection with the transactions contemplated by this Agreement. If
            this Agreement is terminated by either party pursuant to Section
            7.2(c) and at the date of such termination any required approval of
            Duke Energy's performance of its obligations under this Agreement by
            the North Carolina Utilities Commission or The Public Service
            Commission of South Carolina shall not have been obtained, then Duke
            Energy will, in the event of a termination by Westcoast, within
            three Business Days following such termination or in the case of a
            termination by Duke Energy, prior to such termination, pay to
            Westcoast in cash by wire transfer in immediately available funds to
            an account designated by Duke Energy an amount equal to the Expense
            Fee as payment in full of Westcoast's costs and expenses in
            connection with the transactions contemplated by this Agreement.

      (h)   Solely for purposes of this Section 7.3, (x) each reference to 20%
            in the definition of Acquisition Proposal shall be deemed to be 25%
            and (y) for purposes of determining under Section 7.3(b)(ii) whether
            the condition that an Acquisition Proposal shall have been made or a
            proposal or expression of interest by a third party regarding an
            Acquisition Proposal shall have been made or publicly disclosed, the
            condition shall not be deemed to have been met to the extent (i) the
            Acquisition Proposal is expressly conditioned upon completion of the
            transactions contemplated hereby or (ii) the proposal or expression
            of interest regarding an Acquisition Proposal that is only publicly
            disclosed is not bona fide made.

7.4   Effect of Termination Fee Payment

      For greater certainty, the parties hereto agree that if Westcoast pays the
Termination Fee to Duke Energy pursuant to the provisions of Section 7.3, Duke
Energy shall have no other remedy for any breach of this Agreement by Westcoast,
unless Westcoast makes a claim against Duke Energy for breach of a provision of
this Agreement, in which circumstances the liability of Westcoast to Duke Energy
for damages for claims in respect of breaches of this Agreement shall be subject
to a maximum limit equal to the liability of Duke Energy to Westcoast for
damages for claims in respect of breaches of this Agreement plus the Termination
Fee.

Ladies and Gentlemen:

      The undersigned acknowledges that as of the date hereof the undersigned
may be deemed to be an "affiliate" of Westcoast Energy Inc., a corporation
existing under the laws of Canada ("Westcoast"), as the term "affiliate" is used
in and for purposes of paragraphs (c) and (d) of Rule 145 ("Rule 145")
promulgated by the Securities and Exchange Commission (the "SEC") under the
Securities Act of 1933, as amended (the "Securities Act"), although nothing
contained herein shall be construed as an admission by the undersigned that the
undersigned is in fact an affiliate of Westcoast. In connection with the
arrangement pursuant to Section 192 of the Canada Business Corporations Act,
R.S.C. 1995, c. C-44 (the "Arrangement") to be entered pursuant to the terms and
subject to the conditions of the Combination Agreement dated as of September 20,
2001 (the "Agreement"), among Westcoast, 3946509 Canada Inc. ("Exchangeco") and
Duke Energy Corporation, a North Carolina corporation ("Duke Energy"), (i) all
of the shares of Westcoast Common Stock issued and outstanding immediately prior
to the time of the effectiveness of the Arrangement (the "Effective Time") will
be exchanged for cash, exchangeable shares of Exchangeco ("Exchangeable
Shares"), shares of common stock, no par value per share, of Duke Energy ("Duke
Energy Common Stock") or some combination of the foregoing, (ii) immediately
after the Effective Time, Duke Energy and its affiliates will own all of the
issued and outstanding shares of common stock of Westcoast ("Westcoast Common
Stock"), (iii) all of the shares of preferred stock of Westcoast ("Westcoast
Preferred Stock") issued and outstanding immediately prior to the Effective Time
will remain outstanding as shares of Westcoast Preferred Stock, and (iv)
unexpired and unexercised options and warrants to purchase Westcoast Common
Stock ("Westcoast Options") will become options to purchase Duke Energy Common
Stock ("Duke Energy Options"). In, or as a result of, the Arrangement, the
undersigned will receive (i) cash, Exchangeable Shares, Duke Energy Common Stock
or some combination of the foregoing, in exchange for all of the shares of
Westcoast Common Stock owned by the undersigned immediately prior to the
Effective Time and/or (ii) Duke Energy Options in exchange for all of the
Westcoast Options owned by the undersigned immediately prior to the Effective
Time (such Exchangeable Shares, shares of Duke Energy Common Stock, Westcoast
Preferred Stock and Westcoast Options collectively referred to herein as
"Securities").

      The undersigned agrees with Duke Energy not to sell, transfer or otherwise
dispose of any Securities issued to the undersigned in the Arrangement unless
(i) such sale, transfer or other disposition is made in conformity with the
requirements of Rule 145(d) promulgated under the Securities Act, (ii) an
authorized representative of the SEC takes a position in writing reasonably
acceptable to Duke Energy to the effect that the SEC would take no action, or
that the staff of the
<PAGE>

SEC would not recommend that the SEC take action, with respect to such sale,
transfer or other disposition, and a copy of such written position is delivered
to Duke Energy, (iii) the undersigned delivers to Duke Energy a written opinion
of counsel, reasonably acceptable to Duke Energy in form and substance, that
such sale, transfer or other disposition is otherwise exempt from registration
under the Securities Act, or (iv) such sale, transfer or disposition occurs
after the earlier of (A) the first anniversary of the Effective Time, provided
that, at the time of such sale, transfer or other disposition, the undersigned
is not an affiliate of Duke Energy, or (B) the date on which the restrictions
upon sale, transfer or disposition under Rule 145 are eliminated pursuant to
action of the SEC. The undersigned understands that Duke Energy will not be
required to file or maintain the effectiveness of any registration statement
under the Securities Act for the purpose of resale of Securities held by the
undersigned.

      The undersigned acknowledges and agrees that appropriate restrictive
legends will be placed on certificates representing Securities received by the
undersigned in the Arrangement or held by a transferee thereof and that "stop
transfer" orders may be entered in the records of the transfer agent for
Securities with respect to such shares. Such orders will be removed and such
legends will be removed by delivery of substitute certificates upon receipt of
an opinion in form and substance reasonably satisfactory to Duke Energy from
counsel reasonably satisfactory to Duke Energy to the effect that such legends
are no longer required to assure compliance with applicable provisions of the
Securities Act.

      The undersigned acknowledges that the undersigned has carefully read this
letter and understands the requirements hereof and the limitations imposed upon
the distribution, sale, transfer or other disposition of Securities and the
receipt by Duke Energy of this letter is an inducement to Duke Energy to
consummate the Arrangement.

      Notwithstanding any other provision contained herein, this letter and all
obligations of the undersigned hereunder shall terminate upon the termination of
the Agreement in accordance with its terms.

                                          Very truly yours,

                                          ------------------------------

            (c) For greater certainty, a pro rata portion of the total number of
Exchangeable Shares, the total amount of cash, and the total number of Duke
Energy Common Shares received under the Arrangement by any particular holder
will be allocated to every Westcoast Common Share held by that holder at the
Effective Time, so that such holder will receive for each Westcoast Common Share
held by the holder at the Effective Time the same combination of Exchangeable
Shares, cash and/or Duke Energy Common Shares as is received for every other
Westcoast Common Share held by that holder at the Effective Time.
Notwithstanding any provisions of this Plan of Arrangement, of the aggregate
consideration to be received by the holders of Westcoast Common Shares pursuant
to the Arrangement, 50% will consist of cash and 50% will consist of
Exchangeable Shares and/or Duke Energy Common Shares.

                  (i) The consideration which each holder of Westcoast Common
Shares has elected in accordance with Section 2.2(a) to receive in exchange for
such holder's Westcoast Common Shares shall be subject to adjustment and
proration on the following bases:

                  (ii) if the Aggregate Amount of Cash Elected exceeds the Cash
Available, then the amount of cash payable under the Arrangement to each holder
of Westcoast Common Shares who has made a Cash Election or a Mixed Election
shall be prorated (based on the fraction equal to the Cash Available divided by
the Aggregate Amount of Cash Elected)

among all such holders of Westcoast Common Shares who made a Cash Election or a
Mixed Election so that the aggregate amount of cash payable to all such holders
of Westcoast Common Shares who made a Cash Election or a Mixed Election shall be
equal to the Cash Available and each such holder of Westcoast Common Shares who
made a Cash Election or a Mixed Election shall be entitled to receive cash equal
to the amount of cash payable to such holder of Westcoast Common Shares after
giving effect to the proration provisions of this Section 2.2(d)(i) and (x) if
such holder of Westcoast Common Shares has made a further election to receive
Exchangeable Shares or Duke Energy Common Shares in such event, then such holder
shall be deemed to have elected to receive the number of Exchangeable Shares per
Westcoast Common Share equal to the Exchange Ratio or the number of Duke Energy
Common Shares per Westcoast Common Share equal to the Exchange Ratio, as the
case may be, in respect of the balance of such holder's Westcoast Common Shares
in respect of which cash was elected but not available, or (y) if such holder
shall not have made a valid further election to receive Exchangeable Shares or
Duke Energy Common Shares, (A) if such holder is a Canadian Resident, such
holder shall be deemed to have elected to receive the number of Exchangeable
Shares per Westcoast Common Share equal to the Exchange Ratio in respect of the
balance of such holder's Westcoast Common Shares in respect of which cash was
elected but not available and (B) if such holder is not a Canadian Resident,
such holder shall be deemed to have elected to receive the number of Duke Energy
Common Shares per Westcoast Common Share equal to the Exchange Ratio in respect
of the balance of such holder's Westcoast Common Shares in respect of which cash
was elected but not available; and

                  (iii) if the Aggregate Number of Shares Elected exceeds the
Shares Available, then (x) the number of Exchangeable Shares issuable under the
Arrangement to each holder of Westcoast Common Shares who has elected to receive
all or part of the consideration for such holder's Westcoast Common Shares in
the form of Exchangeable Shares shall be prorated (based on the fraction equal
to the Maximum Number of Exchangeable Shares divided by the aggregate number of
Exchangeable Shares that would be issuable to holders of Westcoast Common Shares
based upon the elections made pursuant to Section 2.2(a) before giving effect to
the proration provisions of this Section 2.2(d)) among all holders who have
elected to receive all or part of the consideration for their Westcoast Common
Shares in the form of Exchangeable Shares so that the number of Exchangeable
Shares issuable to all holders who have elected to receive all or part of the
consideration for their Westcoast Common Shares in the form of Exchangeable
Shares under the Arrangement shall be equal to the Maximum Number of
Exchangeable Shares and each such holder shall be entitled to receive that
number of Exchangeable Shares that is equal to the number of Exchangeable Shares
issuable to such holder, after giving effect to the proration provisions of this
Section 2.2(d)(ii)(x), and an amount of cash, without interest, equal to (A) the
difference between the number of Exchangeable Shares such holder elected to
receive pursuant to Section 2.2(a) and the number of Exchangeable Shares such
holder will be entitled to receive after giving effect to the proration
provisions of this Section 2.2(d)(ii)(x), divided by (B) the Exchange Ratio, and
multiplied by (C) Cdn$43.80; and (y) the number of Duke Energy Common Shares
issuable under the Arrangement to each holder of Westcoast Common Shares who has
elected (or is deemed to have elected) to receive all or part of the
consideration for such holder's Westcoast Common Shares, as the case may be, in
the form of Duke Energy Common Shares shall be prorated (based on the fraction
equal to the Maximum Number of

Duke Energy Common Shares divided by the aggregate number of Duke Energy Common
Shares that would be issuable to holders of Westcoast Common Shares based upon
the elections made pursuant to Section 2.2(a) before giving effect to the
proration provisions of this Section 2.2(d)) among all holders who have elected
to receive all or part of the consideration for their Westcoast Common Shares in
the form of Duke Energy Common Shares so that the number of Duke Energy Common
Shares issuable to all holders who have elected to receive all or part of the
consideration for their Westcoast Common Shares in the form of Duke Energy
Common Shares under the Arrangement shall be equal to the Maximum Number of Duke
Energy Common Shares and each such holder shall be entitled to receive that
number of Duke Energy Common Shares that is equal to the number of Duke Energy
Common Shares issuable to such holder, after giving effect to the proration
provisions of this Section 2.2(d)(ii)(y), and an amount of cash, without
interest, equal to (A) the difference between the number of Duke Energy Common
Shares such holder elected (or is deemed to have elected) to receive pursuant to
Section 2.2(a) and the number of Duke Energy Common Shares such holder will be
entitled to receive after giving effect to the proration provisions of this
Section 2.2(d)(ii)(y), divided by (B) the Exchange Ratio, and multiplied by (C)
Cdn$43.80.

            (d) Each of the outstanding First Preferred Shares shall remain
outstanding in accordance with its terms.

            (e) Each Westcoast Option that has not been duly exercised prior to
the Effective Time shall be exchanged for or converted into an option (a
"Replacement Option") to purchase that number of Duke Energy Common Shares equal
to the number of Westcoast Common Shares subject to such Westcoast Option
multiplied by the Exchange Ratio. Such Replacement Option shall provide for an
exercise price per Duke Energy Common Share equal to (x) the exercise price per
Westcoast Common Share of such Westcoast Option immediately prior to the
Effective Time divided by the Exchange Ratio, divided by (y) the Currency
Exchange Rate for United States dollars on the Effective Date, provided that in
no circumstance shall the exercise price per Duke Energy Common Share be less
than $.01 and if the calculation results in an exercise price less than $.01,
the exercise price shall be deemed to be $.01 per Duke Energy Common Share. If
the foregoing calculation results in a Replacement Option being exercisable for
a fraction of a Duke Energy Common Share, then the number of Duke Energy Common
Shares subject to such Replacement Option shall be rounded down to the next
whole number of Duke Energy Common Shares and the total exercise price for the
Replacement Option shall be reduced by the exercise price of the fractional Duke
Energy Common Share, provided that in no circumstance shall the exercise price
per Duke Energy Common Share be less than $.01 and if the calculation results in
an exercise price less than $.01, the exercise price shall be deemed to be $.01
per Duke Energy Common Share. The term to expiry, conditions to and manner of
exercising, vesting schedule and all other terms and conditions of such
Replacement Option will be the same as the terms and conditions of such
Westcoast Option (except for the provisions precluding such options from being
exercised for less than 100 Westcoast Common Shares at one time or requiring
that options be exercised only in blocks of 100 Westcoast Common Shares or
multiples thereof), and any document or agreement previously evidencing such
Westcoast Option shall thereafter evidence and be deemed to evidence such
Replacement Options. Notwithstanding the foregoing, the holder of a Westcoast
Option may, at his or her sole option, notify Duke Energy in writing on or
before the

                                      -11-

Effective Time that he or she wishes to increase the exercise price per Duke
Energy Common Share for his or her Replacement Option in the event that the
value of such Replacement Option immediately after the Effective Time (measured
as the difference between the closing price of the Duke Energy Common Shares on
the NYSE on the Effective Date and the exercise price for such shares pursuant
to such Replacement Option) exceeds the value of the Westcoast Option
immediately before the Effective Time (measured as (x) the difference between
the closing price of the Westcoast Common Shares underlying such Westcoast
Option on The Toronto Stock Exchange on the trading day immediately preceding
the Effective Date and the exercise price for such shares pursuant to such
Westcoast Option, divided by (y) the Currency Exchange Rate for United States
dollars on the Effective Date) to the amount necessary to make the value of such
Replacement Option immediately after the Effective Time equal to the value of
such Westcoast Option immediately before the Effective Time and in the event
such notice is given, the exercise price per Duke Energy Common Share under such
Replacement Option shall be deemed to be equal to such amount; provided that in
no circumstances shall the exercise price per Duke Energy Common Share be less
than $.01.

      2.3   Elections

            (a) The initial election date (the "Initial Election Date") shall be
February 28, 2002, unless otherwise agreed in writing by Duke Energy and
Westcoast. If, after the Letter of Transmittal and Election Form has been
mailed, Westcoast and Duke Energy determine that the Effective Date is not
reasonably likely to occur by the tenth Business Day after the Initial Election
Date, then the date by which Letters of Transmittal and Election Forms must be
received shall be extended to a date which the parties expect to be not more
than 10 Business Days before the Effective Date. In the event that the date by
which Letters of Transmittal and Election Forms must be received is extended,
Westcoast shall provide at least 5 days notice of the new Election Date (and
shall provide such notice prior to the Initial Election Date if practicable) to
holders of Westcoast Common Shares by means of publication, at least once, in
The Globe and Mail; national edition, or any other English language daily
newspaper of general circulation in Canada and in a French language daily
newspaper of general circulation in the Province of Quebec. Any duly completed
Letter of Transmittal and Election Form deposited by the Election Deadline on
the Initial Election Date shall not be required to be re-deposited if the date
by which Letters of Transmittal and Election Forms must be received is extended
pursuant hereto. The Initial Election Date, as extended and published pursuant
to the terms hereof, shall be the "Election Date."

            (b) The Letter of Transmittal and Election Form shall be sent not
less than 21 days prior to the Initial Election Date to each holder of record of
Westcoast Common Shares.

            (c) Each Person who, at or prior to the Election Deadline, is a
holder of record of Westcoast Common Shares will be entitled, with respect to
all or a portion of their shares, to make an election at or prior to the
Election Deadline to receive (i) cash, (ii) Exchangeable Shares (and the
Ancillary Rights), (iii) Duke Energy Common Shares, or (iv) a combination
thereof, in exchange for such holder's Westcoast Common Shares on the basis set
forth herein and in the Letter of Transmittal and Election Form; provided that,
notwithstanding anything to the contrary herein, a holder of Westcoast Common
Shares who is not a Canadian Resident will not be entitled to elect to receive
Exchangeable Shares (and the Ancillary Rights) and any

                                      -12-
                              PLAN OF ARRANGEMENT
<PAGE>

such election otherwise made by any such holder shall be and be deemed to be an
election to receive Duke Energy Common Shares.

            (d) Holders of Westcoast Common Shares who are Canadian Residents,
other than any such holder who is exempt from tax under the ITA, and who have
elected (or who are deemed to have elected) to receive Exchangeable Shares (and
the Ancillary Rights) shall be entitled to make an income tax election pursuant
to subsection 85(1) of the ITA or, if the holder is a partnership, subsection
85(2) of the ITA (and in each case, where applicable, the analogous provisions
of provincial income tax law) with respect to the transfer of their Westcoast
Common Shares to Exchangeco by providing two signed copies of the necessary
prescribed election forms to the Depositary within 90 days following the
Effective Date, duly completed with the details of the number of Westcoast
Common Shares transferred and the applicable agreed amounts for the purposes of
such elections. Thereafter, subject to the election forms being correct and
complete and complying with the provisions of the ITA (or any applicable
provincial income tax law), the forms will be signed by Exchangeco and returned
to such holders of Westcoast Common Shares within 30 days after the receipt
thereof by the Depositary for filing with CCRA (or the applicable provincial
taxing authority). Exchangeco will not be responsible for the proper completion
of any election form and, except for Exchangeco's obligation to return duly
completed election forms which are received by the Depositary within 90 days
following the Effective Date, within 30 days after the receipt thereof by the
Depositary, Exchangeco will not be responsible for any taxes, interest,
penalties or any other costs or damages resulting from the failure by a holder
of Westcoast Common Shares to properly complete or file the election forms in
the form and manner and within the time prescribed by the ITA (or any applicable
provincial income tax law). In its sole discretion, Exchangeco may choose to
sign and return an election form received more than 90 days following the
Effective Date, but Exchangeco will have no obligation to do so.

      2.4   Adjustments to Exchange Ratio

      The Exchange Ratio, including the minimum and maximum Exchange Ratio used
in the calculation thereof, shall be proportionately and appropriately adjusted
to reflect fully the effect of (a) any stock split, reverse split, stock
dividend (including any dividend or distribution of securities convertible into
Duke Energy Common Shares or Westcoast Common Shares), reorganization,
recapitalization or other like change with respect to Duke Energy Common Shares
or Westcoast Common Shares and (b) any extraordinary dividend or distribution
with respect to Duke Energy Common Shares (other than a dividend or distribution
referenced in clause (a)), but only if the Weighted Average Trading Price of
Duke Energy Common Shares is less than $36.88 as of the Effective Date, in each
case of clause (a) or (b) the record date for which occurs after the date of the
Combination Agreement and prior to the Effective Time. Regular quarterly cash
dividends and increases therein shall not be considered extraordinary for
purposes of the preceding sentence.

      3.1   Rights of Dissent

      Holders of Westcoast Common Shares may exercise rights of dissent with
respect to such Westcoast Common Shares pursuant to and in the manner set forth
in section 190 of the CBCA as modified by the Interim Order and this Section 3.1
(the "Dissent Rights") in connection with the Arrangement. Holders of Westcoast
Common Shares who duly exercise such rights of dissent and who:

            (a) are ultimately determined to be entitled to be paid fair value
  for their Westcoast Common Shares shall be deemed to have transferred such
  Westcoast Common Shares as of the Effective Time, without any further act or
  formality and free and clear of all liens, claims and encumbrances, to
  Exchangeco, in consideration for a payment of cash from Exchangeco equal to
  such fair value; or

            (b) are ultimately determined not to be entitled, for any reason, to
  be paid fair value for their Westcoast Common Shares, shall be deemed to have
  participated in the Arrangement, as of the Effective Time, on the same basis
  as a non-dissenting holder of Westcoast Common Shares who did not make an
  election and shall receive cash, Exchangeable Shares or Duke Energy Common
  Shares on the same basis as holders of Non-Election Shares,

but in no case shall Duke Energy, Exchangeco, Callco, Westcoast or any other
Person be required to recognize any Dissenting Shareholder as a holder of
Westcoast Common Shares after the Effective Time, and the names of each
Dissenting Shareholder shall be deleted from the register of holders of
Westcoast Common Shares at the Effective Time.

                       CERTIFICATES AND FRACTIONAL SHARES

      4.1   Payment of Cash

      At or promptly after the Effective Time, Exchangeco shall deposit with the
Depositary, for the benefit of the holders of Westcoast Common Shares who will
receive cash in connection with the Arrangement, cash in the amount of the Cash
Available. Upon surrender to the Depositary for transfer to Exchangeco of a
certificate which immediately prior to or upon the Effective Time represented
Westcoast Common Shares in respect of which the holder is entitled to receive
cash under the Arrangement, together with a duly completed Letter of Transmittal
and Election Form, and such other documents and instruments as would have been
required to effect the transfer of the shares formerly represented by such
certificate under the CBCA and the by-laws of Westcoast and such additional
documents and instruments as the Depositary may reasonably require, the holder
of such surrendered certificate shall be entitled to receive in exchange
therefor, and after the Effective Time the Depositary shall deliver to such
holder the amount of cash such holder is entitled to receive under the
Arrangement (together with any unpaid dividends or distributions declared on the
Westcoast Common Shares, if any, prior to the

                                      -14-

Effective Time), and any certificate so surrendered shall forthwith be
transferred to Exchangeco. In the event of a transfer of ownership of such
Westcoast Common Shares that was not registered in the securities register of
Westcoast, the amount of cash payable for such Westcoast Common Shares under the
Arrangement may be delivered to the transferee if the certificate representing
such Westcoast Common Shares is presented to the Depositary as provided above,
accompanied by all documents required to evidence and effect such transfer and
to evidence that any applicable stock transfer taxes have been paid. Until
surrendered as contemplated by this Section 4.1, each certificate which
immediately prior to or upon the Effective Time represented one or more
outstanding Westcoast Common Shares that, under the Arrangement, were exchanged
or were deemed to be exchanged for cash pursuant to Section 2.2 shall be deemed
at all times after the Effective Time to represent only the right to receive
upon such surrender the cash payment contemplated by this Section 4.1.

      4.2   Issuance of Certificates Representing Exchangeable Shares

      At or promptly after the Effective Time, Exchangeco shall deposit with the
Depositary, for the benefit of the holders of Westcoast Common Shares who will
receive Exchangeable Shares (and the Ancillary Rights) in connection with the
Arrangement, certificates representing the Maximum Number of Exchangeable
Shares. Upon surrender to the Depositary for transfer to Exchangeco of a
certificate which immediately prior to or upon the Effective Time represented
Westcoast Common Shares in respect of which the holder is entitled to receive
Exchangeable Shares under the Arrangement, together with a duly completed Letter
of Transmittal and Election Form and such other documents and instruments as
would have been required to effect the transfer of the shares formerly
represented by such certificate under the CBCA and the by-laws of Westcoast and
such additional documents and instruments as the Depositary may reasonably
require, the holder of such surrendered certificate shall be entitled to receive
in exchange therefor, and after the Effective Time the Depositary shall deliver
to such holder, a certificate representing that number (rounded down to the
nearest whole number) of Exchangeable Shares which such holder has the right to
receive (together with any unpaid dividends or distributions declared on the
Westcoast Common Shares prior to the Effective Time) and any certificate so
surrendered shall forthwith be transferred to Exchangeco. No interest shall be
paid or accrued on the cash in lieu of fractional shares, if any, or on unpaid
dividends and distributions, if any, payable to holders of certificates that
formerly represented Westcoast Common Shares. In the event of a transfer of
ownership of Westcoast Common Shares that was not registered in the securities
register of Westcoast, a certificate representing the proper number of
Exchangeable Shares (together with any unpaid dividends or distributions
declared on the Westcoast Common Shares prior to the Effective Time) may be
issued to the transferee if the certificate representing such Westcoast Common
Shares is presented to the Depositary as provided above, accompanied by all
documents required to evidence and effect such transfer and to evidence that any
applicable stock transfer taxes have been paid. Until surrendered as
contemplated by this Section 4.2, each certificate which immediately prior to or
upon the Effective Time represented one or more Westcoast Common Shares that,
under the Arrangement, were exchanged or were deemed to be exchanged for
Exchangeable Shares pursuant to Section 2.2 shall be deemed at all times after
the Effective Time, but subject to Section 4.5, to represent only the right to
receive upon such surrender a certificate representing that number (rounded down
to the nearest whole number) of Exchangeable Shares (together with any unpaid
dividends or distributions declared

                                      -15-

on the Westcoast Common Shares prior to the Effective Time) which such holder
has the right to receive.

      4.3   Issuance of Certificates Representing Duke Energy Common Shares

      At or promptly after the Effective Time, Exchangeco shall deposit with the
Depositary, for the benefit of the holders of Westcoast Common Shares who will
receive Duke Energy Common Shares in connection with the Arrangement,
certificates representing the Maximum Number of Duke Energy Common Shares. Upon
surrender to the Depositary for transfer to Exchangeco of a certificate which
immediately prior to or upon the Effective Time represented Westcoast Common
Shares in respect of which the holder is entitled to receive Duke Energy Common
Shares under the Arrangement, together with a duly completed Letter of
Transmittal and Election Form and such other documents and instruments as would
have been required to effect the transfer of the shares formerly represented by
such certificate under the CBCA and the by-laws of Westcoast and such additional
documents and instruments as the Depositary may reasonably require, the holder
of such surrendered certificate shall be entitled to receive in exchange
therefor, and after the Effective Time the Depositary shall deliver to such
holder, a certificate representing that number (rounded down to the nearest
whole number) of Duke Energy Common Shares which such holder has the right to
receive (together with any unpaid dividends or distributions declared on the
Westcoast Common Shares prior to the Effective Time) and any certificate so
surrendered shall forthwith be transferred to Exchangeco. No interest shall be
paid or accrued on the cash in lieu of fractional shares, if any, or on unpaid
dividends and distributions, if any, payable to holders of certificates that
formerly represented Westcoast Common Shares. In the event of a transfer of
ownership of Westcoast Common Shares that was not registered in the securities
register of Westcoast, a certificate representing the proper number of Duke
Energy Common Shares (together with any unpaid dividends or distributions
declared on the Westcoast Common Shares prior to the Effective Time) may be
issued to the transferee if the certificate representing such Westcoast Common
Shares is presented to the Depositary as provided above, accompanied by all
documents required to evidence and effect such transfer and to evidence that any
applicable stock transfer taxes have been paid. Until surrendered as
contemplated by this Section 4.3, each certificate which immediately prior to or
upon the Effective Time represented one or more Westcoast Common Shares, under
the Arrangement, that were exchanged or were deemed to be exchanged for Duke
Energy Common Shares pursuant to Section 2.2 shall be deemed at all times after
the Effective Time, but subject to Section 4.5, to represent only the right to
receive upon such surrender a certificate representing that number (rounded down
to the nearest whole number) of Duke Energy Common Shares (together with any
unpaid dividends or distributions declared prior to the Effective Time) which
such holder has the right to receive.

      4.4   Distributions with Respect to Unsurrendered Certificates

      No dividends or other distributions paid, declared or made with respect to
Exchangeable Shares or Duke Energy Common Shares, in each case with a record
date after the Effective Time, shall be paid to the holder of any unsurrendered
certificate which immediately prior to the Effective Time represented
outstanding Westcoast Common Shares that were exchanged for Exchangeable Shares
or Duke Energy Common Shares pursuant to Section 2.2 unless and until the holder
of such certificate shall comply with the provisions of Section 4.2 or 4.3, as

                                      -16-
                              PLAN OF ARRANGEMENT
<PAGE>

applicable. Subject to applicable law, at the time such holder shall have
complied with the provisions of Section 4.2 or 4.3, as applicable, (or, in the
case of clause (ii) below, at the appropriate payment date), there shall be paid
to the holder of the certificates formerly representing Westcoast Common Shares,
without interest, (i) the amount of dividends or other distributions with a
record date after the Effective Time theretofore paid with respect to the
Exchangeable Shares or Duke Energy Common Shares, as the case may be, to which
such holder is entitled pursuant hereto and (ii) on the appropriate payment
date, the amount of dividends or other distributions with a record date after
the Effective Time but prior to the date of compliance by such holder with the
provisions of Section 4.2 or 4.3 and a payment date subsequent to the date of
such compliance and payable with respect to such Exchangeable Shares or Duke
Energy Common Shares, as the case may be.

      4.5   No Fractional Shares

      No certificates representing fractional Exchangeable Shares or fractional
Duke Energy Common Shares shall be issued upon compliance with the provisions of
Section 4.2 or 4.3 and no dividend, stock split or other change in the capital
structure of Exchangeco or Duke Energy shall relate to any such fractional
security and such fractional interests shall not entitle the owner thereof to
exercise any rights as a security holder of Exchangeco or Duke Energy. In lieu
of any such fractional securities, each holder otherwise entitled to a
fractional interest in an Exchangeable Share or to a fractional interest in a
Duke Energy Common Share will be entitled to receive a cash payment from the
Depositary equal to the product of such fractional interest and the Weighted
Average Trading Price of Duke Energy Common Shares, such amount to be provided
to the Depositary by Exchangeco upon request. Such payment with respect to
fractional shares is merely intended to provide a mechanical rounding off of,
and is not separately bargained for, consideration. If more than one certificate
formerly representing Westcoast Common Shares are surrendered for the account of
the same holder, the number of Exchangeable Shares or Duke Energy Common Shares
for which such certificates have been surrendered shall be computed on the basis
of the aggregate number of Westcoast Common Shares represented by the
certificates so surrendered. On the date of the notice referred to in Section
7.2 of the Exchangeable Share Provisions, the aggregate number of Exchangeable
Shares and the aggregate number of Duke Energy Common Shares for which no
certificates were issued as a result of the foregoing provisions of this Section
4.5 shall be deemed to have been surrendered by the Depositary for no
consideration to Exchangeco.

      4.6   Lost Certificates

      In the event any certificate which immediately prior to the Effective Time
represented one or more outstanding Westcoast Common Shares that were exchanged
pursuant to Section 2.2 shall have been lost, stolen or destroyed, upon the
making of an affidavit of that fact by the holder of Westcoast Common Shares
claiming such certificate to be lost, stolen or destroyed, the Depositary will
issue in exchange for such lost, stolen or destroyed certificate, any cash
pursuant to Section 4.1 and/or one or more certificates representing one or more
Exchangeable Shares pursuant to Section 4.2 or Duke Energy Common Shares
pursuant to Section 4.3 (and any dividends or distributions with respect
thereto) in each case deliverable in accordance with Section 2.2. When
authorizing such payment in exchange for any lost, stolen or destroyed
certificate, the holder to whom cash and/or certificates representing
Exchangeable Shares or

                                      -17-

<PAGE>

Duke Energy Common Shares are to be issued shall, as a condition precedent to
the issuance thereof, give a bond satisfactory to Westcoast, Exchangeco, Duke
Energy and their respective transfer agents in such sum as Westcoast, Exchangeco
or Duke Energy may direct or otherwise indemnify Westcoast, Exchangeco and Duke
Energy in a manner satisfactory to Westcoast, Exchangeco and Duke Energy against
any claim that may be made against Westcoast, Exchangeco or Duke Energy with
respect to the certificate alleged to have been lost, stolen or destroyed.

      4.7   Extinguishment of Rights

      Any certificate which immediately prior to the Effective Time represented
outstanding Westcoast Common Shares that are not held by a Dissenting
Shareholder who is ultimately entitled to be paid fair value of the Westcoast
Common Shares held by such Dissenting Shareholder but was exchanged or was
deemed to have been exchanged pursuant to Section 2.2, that has not been

or the Depositary is required to deduct and withhold with respect to such
payment under the ITA, the United States Internal Revenue Code of 1986 or any
provision of federal, provincial, territorial, state, local or foreign tax law,
in each case, as amended. To the extent that amounts are so withheld, such
withheld amounts shall be treated for all purposes hereof as having been paid to
the holder of the shares in respect of which such deduction and withholding was
made, provided that such withheld amounts are actually remitted to the
appropriate taxing authority. To the extent that the amount so required to be
deducted or withheld from any payment to a holder exceeds the cash portion of
the consideration otherwise payable to the holder, Westcoast, Exchangeco,
Callco, Duke Energy and the Depositary are hereby authorized to sell or
otherwise dispose of such portion of the consideration as is necessary to
provide sufficient funds to Westcoast, Exchangeco, Callco, Duke Energy or the
Depositary, as the case may be, to enable it to comply with such deduction or

      Any Exchangeable Shares or Duke Energy Common Shares, together with any

representing Westcoast Common Shares who have not theretofore complied with
Sections 4.1, 4.2 or 4.3 shall thereafter look only to Exchangeco for payment of
any claim to cash, Exchangeable Shares, Duke Energy Common Shares, cash in lieu
of fractional shares thereof or dividends or distributions, if any, in respect
thereof.

                               EXCHANGEABLE SHARES

      5.1   Callco Liquidation Call Right

            (a) Callco shall have the overriding right (the "Liquidation Call
Right"), in the event of and notwithstanding the proposed liquidation,
dissolution or winding-up of Exchangeco or any other distribution of the assets
of Exchangeco among its shareholders for the purpose of winding-up its affairs,
pursuant to Article 5 of the Exchangeable Share Provisions, to purchase from all
but not less than all of the holders of Exchangeable Shares (other than any
holder of Exchangeable Shares which is an affiliate of Duke Energy) on the
Liquidation Date all but not less than all of the Exchangeable Shares held by
each such holder upon payment by Callco to each such holder of the Exchangeable
Share Price applicable on the last Business Day prior to the Liquidation Date
(the "Liquidation Call Purchase Price") in accordance with Section 5.1(c). In
the event of the exercise of the Liquidation Call Right by Callco, each holder
shall be obligated to sell all the Exchangeable Shares held by such holder to
Callco on the Liquidation Date upon payment by Callco to such holder of the
Liquidation Call Purchase Price for each such Exchangeable Share, whereupon
Exchangeco shall have no obligation to pay any Liquidation Amount to the holders
of such shares so purchased by Callco.

            (b) To exercise the Liquidation Call Right, Callco must notify
Exchangeco and Exchangeco's transfer agent (the "Transfer Agent"), as agent for
the holders of Exchangeable Shares, and Exchangeco of Callco's intention to
exercise such right at least 45 days before the Liquidation Date in the case of
a voluntary liquidation, dissolution or winding-up of Exchangeco or any other
voluntary distribution of the assets of Exchangeco among its shareholders for
the purpose of winding-up its affairs, and at least five Business Days before
the Liquidation Date in the case of an involuntary liquidation, dissolution or
winding-up of Exchangeco or any other involuntary distribution of the assets of
Exchangeco among its shareholders for the purpose of winding up its affairs. The
Transfer Agent will notify the holders of Exchangeable Shares as to whether
Callco has exercised the Liquidation Call Right forthwith after the expiry of
the period during which the same may be exercised by Callco. If

                                      -19-
                              PLAN OF ARRANGEMENT
<PAGE>

Callco exercises the Liquidation Call Right, then on the Liquidation Date,
Callco will purchase and the holders of Exchangeable Shares will sell all of the
Exchangeable Shares then outstanding for a price per share equal to the
Liquidation Call Purchase Price.

            (c) For the purposes of completing the purchase of the Exchangeable
Shares pursuant to the Liquidation Call Right, Callco shall deposit or cause to
be deposited with the Transfer Agent, on or before the Liquidation Date, the
Exchangeable Share Consideration representing the total Liquidation Call
Purchase Price. Provided that such Exchangeable Share Consideration has been so
deposited with the Transfer Agent, on and after the Liquidation Date, the
holders of the Exchangeable Shares shall cease to be holders of the Exchangeable
Shares and shall not be entitled to exercise any of the rights of holders in
respect thereof (including any rights under the Voting and Exchange Trust
Agreement), other than the right to receive their proportionate part of the
total Liquidation Call Purchase Price payable by Callco, without interest, upon
presentation and surrender by the holder of certificates representing the
Exchangeable Shares held by such holder and the holder shall on and after the
Liquidation Date be considered and deemed for all purposes to be the holder of
the Duke Energy Common Shares to which such holder is entitled. Upon surrender
to the Transfer Agent of a certificate or certificates representing Exchangeable
Shares, together with such other documents and instruments as may be required to
effect a transfer of Exchangeable Shares under the CBCA and the by-laws of
Exchangeco and such additional documents and instruments as the Transfer Agent
may reasonably require, the holder of such surrendered certificate or
certificates shall be entitled to receive in exchange therefor, and the Transfer
Agent on behalf of Callco shall deliver to such holder, the Exchangeable Share
Consideration to which such holder is entitled. If Callco does not exercise the
Liquidation Call Right in the manner described above, on the Liquidation Date
the holders of the Exchangeable Shares will be entitled to receive in exchange
therefor the Liquidation Amount otherwise payable by Exchangeco in connection
with the liquidation, dissolution or winding-up of Exchangeco pursuant to
Article 5 of the Exchangeable Share Provisions.

      5.2   Callco Redemption Call Right

      In addition to Callco's rights contained in the Exchangeable Share
Provisions, including the Retraction Call Right (as defined in the Exchangeable
Share Provisions), Callco shall have the following rights in respect of the
Exchangeable Shares:

            (a) Callco shall have the overriding right (the "Redemption Call
Right"), in the event of and notwithstanding the proposed redemption of the
Exchangeable Shares by Exchangeco pursuant to Article 7 of the Exchangeable
Share Provisions, to purchase from all but not less than all of the holders of
Exchangeable Shares (other than any holder of Exchangeable Shares which is an
affiliate of Duke Energy) on the Redemption Date all but not less than all of
the Exchangeable Shares held by each such holder upon payment by Callco to each
such holder of the Exchangeable Share Price applicable on the last Business Day
prior to the Redemption Date (the "Redemption Call Purchase Price") in
accordance with 5.2(c). In the event of the exercise of the Redemption Call
Right by Callco, each holder shall be obligated to sell all the Exchangeable
Shares held by such holder to Callco on the Redemption Date upon payment by
Callco to such holder of the Redemption Call Purchase Price for each

                                      -20-
                              PLAN OF ARRANGEMENT
<PAGE>

such Exchangeable Share, whereupon Exchangeco shall have no obligation to
redeem, or to pay the Redemption Price in respect of, such shares so purchased
by Callco.

            (b) To exercise the Redemption Call Right, Callco must notify the
Transfer Agent, as agent for the holders of Exchangeable Shares, and Exchangeco
of Callco's intention to exercise such right at least 60 days before the
Redemption Date, except in the case of a redemption occurring as a result of a
Duke Energy Control Transaction, an Exchangeable Share Voting Event, an Exempt
Exchangeable Share Voting Event or a Distribution Date (each as defined in the
Exchangeable Share Provisions), in which case Callco shall so notify the
Transfer Agent and Exchangeco on or before the Redemption Date. The Transfer
Agent will notify the holders of the Exchangeable Shares as to whether Callco
has exercised the Redemption Call Right forthwith after the expiry of the period
during which the same may be exercised by Callco. If Callco exercises the
Redemption Call Right, then on the Redemption Date, Callco will purchase and the
holders of Exchangeable Shares will sell all of the Exchangeable Shares then
outstanding for a price per share equal to the Redemption Call Purchase Price.

            (c) For the purposes of completing the purchase of the Exchangeable
Shares pursuant to the Redemption Call Right, Callco shall deposit or cause to
be deposited with the Transfer Agent, on or before the Redemption Date, the
Exchangeable Share Consideration representing the total Redemption Call Purchase
Price. Provided that such Exchangeable Share Consideration has been so deposited
with the Transfer Agent, on and after the Redemption Date the holders of the
Exchangeable Shares shall cease to be holders of the Exchangeable Shares and
shall not be entitled to exercise any of the rights of holders in respect
thereof (including any rights under the Voting and Exchange Trust Agreement),
other than the right to receive their proportionate part of the total Redemption
Call Purchase Price payable by Callco, without interest, upon presentation and
surrender by the holder of certificates representing the Exchangeable Shares
held by such holder and the holder shall on and after the Redemption Date be
considered and deemed for all purposes to be the holder of the Duke Energy
Common Shares to which such holder is entitled. Upon surrender to the Transfer
Agent of a certificate or certificates representing Exchangeable Shares,
together with such other documents and instruments as may be required to effect
a transfer of Exchangeable Shares under the CBCA and the by-laws of Exchangeco
and such additional documents and instruments as the Transfer Agent may
reasonably require, the holder of such surrendered certificate or certificates
shall be entitled to receive in exchange therefor, and the Transfer Agent on
behalf of Callco shall deliver to such holder, the Exchangeable Share
Consideration to which such holder is entitled. If Callco does not exercise the
Redemption Call Right in the manner described above, on the Redemption Date the
holders of the Exchangeable Shares will be entitled to receive in exchange
therefor the Redemption Price otherwise payable by Exchangeco in connection with
the redemption of the Exchangeable Shares pursuant to Article 7 of the
Exchangeable Share Provisions.

            (i) there are less than twenty percent (20%) of the number of
      Exchangeable Shares issuable on the Effective Date outstanding (other than
      Exchangeable Shares held by Duke Energy and its affiliates, as such number
      of shares may be adjusted as deemed appropriate by the Board of Directors
      to give effect to any subdivision or consolidation of or stock dividend on
      the Exchangeable Shares, any issue or distribution of rights to acquire
      Exchangeable Shares or securities exchangeable for or convertible into
      Exchangeable Shares, any issue or distribution of other securities or
      rights or evidences of indebtedness or assets, or any other capital
      reorganization or other transaction affecting the Exchangeable Shares), in
      which case the Board of Directors may accelerate such redemption date to
      such date prior to the eighth anniversary of the Effective Date as it may
      determine, upon at least 60 days' prior written notice to the registered
      holders of the Exchangeable Shares and the Trustee;

            (ii) a Duke Energy Control Transaction occurs, in which case,
      provided that the Board of Directors determines, in good faith and in its
      sole discretion, that it is not reasonably practicable to substantially
      replicate the terms and conditions of the Exchangeable Shares in
      connection with such Duke Energy Control Transaction and that

      the redemption of all but not less than all of the outstanding
      Exchangeable Shares is necessary to enable the completion of such Duke
      Energy Control Transaction in accordance with its terms, the Board of
      Directors may accelerate such redemption date to such date prior to the
      eighth anniversary of the Effective Date as it may determine, upon such
      number of days' prior written notice to the registered holders of the
      Exchangeable Shares and the Trustee as the Board of Directors may
      determine to be reasonably practicable in such circumstances;

            (iii) an Exchangeable Share Voting Event is proposed, in which case,

      its sole discretion, that it is not reasonably practicable to accomplish
      the business purpose intended by the Exchangeable Share Voting Event in
      any other commercially reasonable manner that does not result in an
      Exchangeable Share Voting Event, which business purpose must be bona fide
      and not for the primary purpose of causing the occurrence of a Redemption
      Date, the redemption date shall be the Business Day prior to the record
      date for any meeting or vote of the holders of the Exchangeable Shares to
      consider the Exchangeable Share Voting Event and the Board of Directors
      shall give such number of days' prior written notice of such redemption to
      the registered holders of the Exchangeable Shares and the Trustee as the
      Board of Directors may determine to be reasonably practicable in such
      circumstances; or

            (iv) an Exempt Exchangeable Share Voting Event is proposed and the
      holders of the Exchangeable Shares fail to take the necessary action at a
      meeting or other vote of holders of Exchangeable Shares, to approve or
      disapprove, as applicable, the Exempt Exchangeable Share Voting Event, in
      which case the redemption date shall be the Business Day following the day
      on which the holders of the Exchangeable Shares failed to take such
      action,

      provided, however, that the accidental failure or omission to give any
      notice of redemption under clauses (a), (b) or (c) above to any of such

      2.1   The Exchangeable Shares shall be entitled to a preference over the
Common Shares and any other shares ranking junior to the Exchangeable Shares
with respect to the payment of dividends and the distribution of assets in the
event of the liquidation, dissolution or winding-up of the Company, whether
voluntary or involuntary, or any other distribution of the assets of the

                                   ARTICLE 3

                                   DIVIDENDS

      3.1   A holder of an Exchangeable Share shall be entitled to receive and
the Board of Directors shall, subject to applicable law, on each Duke Energy
Dividend Declaration Date, declare a dividend on each Exchangeable Share:

            (a) in the case of a cash dividend declared on the Duke Energy
Common Shares, in an amount in cash for each Exchangeable Share in U.S. dollars,
or the Canadian Dollar Equivalent thereof on the Duke Energy Dividend
Declaration Date, in each case, corresponding to the cash dividend declared on
each Duke Energy Common Share;

            (b) in the case of a stock dividend declared on the Duke Energy
Common Shares to be paid in Duke Energy Common Shares subject to Section 3.2, by
the issue or transfer by the Company of such number of Exchangeable Shares for
each Exchangeable Share as is equal to the number of Duke Energy Common Shares
to be paid on each Duke Energy Common Share; or

            (c) in the case of a dividend declared on the Duke Energy Common
Shares in property other than cash or Duke Energy Common Shares, in such type
and amount of property for each Exchangeable Share as is the same as or
economically equivalent to (to be determined by the Board of Directors as
contemplated by Section 3.6) the type and amount of property declared as a
dividend on each Duke Energy Common Share.

      Such dividends shall be paid out of money, assets or property of the
Company properly applicable to the payment of dividends, or out of authorized
but unissued shares of the Company, as applicable.

      3.2   In the case of a stock dividend declared on the Duke Energy Common
Shares to be paid in Duke Energy Common Shares, in lieu of declaring the stock
dividend contemplated by Section 3.1(b) on the Exchangeable Shares, the Board of
Directors may, in good faith and in its discretion and subject to applicable law
and to obtaining all required regulatory approvals, subdivide, redivide or
change (the "Subdivision") each issued and unissued Exchangeable Share on the
basis that each Exchangeable Share before the subdivision becomes a number of
Exchangeable Shares equal to the sum of (i) one Duke Energy Common Share and
(ii) the number of Duke Energy Common shares to be paid as a share dividend on
each Duke Energy Common Share. In making such Subdivision, the Board of
Directors shall consider the effect thereof upon the then outstanding
Exchangeable Shares and the general taxation consequences of the Subdivision to
the holders of the Exchangeable Shares. In such instance, and notwithstanding
any other provision hereof, such Subdivision shall become effective on the

                                      1-8
<PAGE>

effective date specified in Section 3.4 without any further act or formality on
the part of the Board of Directors or of the holders of Exchangeable Shares.

      3.3   Cheques of the Company payable at par at any branch of the bankers
of the Company shall be issued in respect of any cash dividends contemplated by
Section 3.1(a) and the sending of such a cheque to each holder of an
Exchangeable Share shall satisfy the cash dividend represented thereby unless
the cheque is not paid on presentation. Subject to applicable law, certificates
registered in the name of the registered holder of Exchangeable Shares shall be
issued or transferred in respect of any stock dividends contemplated by Section
3.1(b) or any Subdivision contemplated by Section 3.2 and the sending of such a
certificate to each holder of an Exchangeable Share shall satisfy the stock
dividend represented thereby. Such other type and amount of property in respect
of any dividends contemplated by Section 3.1(c) shall be issued, distributed or
transferred by the Company in such manner as it shall determine and the
issuance, distribution or transfer thereof by the Company to each holder of an
Exchangeable Share shall satisfy the dividend represented thereby. No holder of
an Exchangeable Share shall be entitled to recover by action or other legal
process against the Company any dividend that is represented by a cheque that
has not been duly presented to the Company's bankers for payment or that
otherwise remains unclaimed for a period of six years from the date on which
such dividend was first payable.

      3.4   The record date for the determination of the holders of Exchangeable
Shares entitled to receive payment of, and the payment date for, any dividend
declared on the Exchangeable Shares under Section 3.1 shall be the same dates as
the record date and payment date, respectively, for the corresponding dividend
declared on the Duke Energy Common Shares. The record date for the determination
of the holders of Exchangeable Shares entitled to receive Exchangeable Shares in
connection with any Subdivision of the Exchangeable Shares under Section 3.2 and
the effective date of such Subdivision shall be the same dates as the record
date and payment date, respectively, for the corresponding dividend declared on
the Duke Energy Common Shares.

      3.5   If on any payment date for any dividends declared on the
Exchangeable Shares under Section 3.1 the dividends are not paid in full on all
of the Exchangeable Shares then outstanding, any such dividends that remain
unpaid shall be paid on a subsequent date or dates determined by the Board of
Directors on which the Company shall have sufficient moneys, assets or property
properly applicable to the payment of such dividends.

      3.6   The Board of Directors shall determine, in good faith and in its
sole discretion, economic equivalence for the purposes of Sections 3.1 and 3.2,
and each such determination shall be conclusive and binding on the Company and
its shareholders. In making each such determination, the following factors
shall, without excluding other factors determined by the Board of Directors to
be relevant, be considered by the Board of Directors:

            (a) in the case of any stock dividend or other distribution payable
in Duke Energy Common Shares, the number of such shares issued in proportion to
the number of Duke Energy Common Shares previously outstanding;

                                      1-9
<PAGE>

            (b) in the case of the issuance or distribution of any rights,
options or warrants to subscribe for or purchase Duke Energy Common Shares (or
securities exchangeable for or convertible into or carrying rights to acquire
Duke Energy Common Shares), the relationship between the exercise price of each
such right, option or warrant and the Current Market Price;

            (c) in the case of the issuance or distribution of any other form of
property (including any shares or securities of Duke Energy of any class other
than Duke Energy Common Shares, any rights, options or warrants other than those
referred to in Section 3.6(b) above, any evidences of indebtedness of Duke
Energy or any assets of Duke Energy) the relationship between the fair market
value (as determined by the Board of Directors in the manner above contemplated)
of such property to be issued or distributed with respect to each outstanding
Duke Energy Common Share and the Current Market Price; and

            (d) in all such cases, the general taxation consequences of the
relevant event to holders of Exchangeable Shares to the extent that such
consequences may differ from the taxation consequences to holders of Duke Energy
Common Shares as a result of differences between taxation laws of Canada and the
United States (except for any differing consequences arising as a result of
differing marginal taxation rates and without regard to the individual
circumstances of holders of Exchangeable Shares).

      3.7   Except as provided in this Article 3, the holders of Exchangeable
Shares shall not be entitled to receive dividends in respect thereof.
Notwithstanding any provision of this Article 3 to the contrary, if the
Exchangeable Share Price is paid to a holder of an Exchangeable Share by Callco
pursuant to the Retraction Call Right, the Redemption Call Right or the
Liquidation Call Right or by Duke Energy pursuant to the Exchange Right or the
Automatic Exchange Right, the holder of the Exchangeable Share shall cease to
have any right to be paid any amount by the Company in respect of any unpaid
dividends on such Exchangeable Shares.

                                   ARTICLE 4

                              CERTAIN RESTRICTIONS

      4.1   So long as any of the Exchangeable Shares are outstanding, the
Company shall not at any time without, but may at any time with, the approval of
the holders of the Exchangeable Shares given as specified in Section 10.2 of
these share provisions:

            (a) pay any dividends on the Common Shares or any other shares
ranking junior to the Exchangeable Shares with respect to the payment of
dividends, other than stock dividends payable in Common Shares or any such other
shares ranking junior to the Exchangeable Shares, as the case may be;

            (b) redeem or purchase or make any capital distribution in respect
of Common Shares or any other shares ranking junior to the Exchangeable Shares
with respect to the payment of dividends or on any liquidation, dissolution or
winding-up of the Company or any other distribution of the assets of the
Company;

            (c) redeem or purchase any other shares of the Company ranking
equally with the Exchangeable Shares with respect to the payment of dividends or
on any liquidation,

                                      1-10
<PAGE>

dissolution or winding-up of the Company or any other distribution of the assets
of the Company; or

            (d) issue any Exchangeable Shares or any other shares of the Company
ranking equally with, or superior to, the Exchangeable Shares other than by way
of stock dividends to the holders of such Exchangeable Shares;

      The restrictions in Sections 4.1(a), (b), (c) and (d) shall not apply if
all dividends on the outstanding Exchangeable Shares corresponding to dividends
declared and paid to date on the Duke Energy Common Shares shall have been
declared and paid on the Exchangeable Shares.

                                   ARTICLE 5

                           DISTRIBUTION ON LIQUIDATION

      5.1   In the event of the liquidation, dissolution or winding-up of the
Company or any other distribution of the assets of the Company among its
shareholders for the purpose of winding up its affairs, a holder of Exchangeable
Shares shall be entitled, subject to applicable law and to the exercise by
Callco of the Liquidation Call Right, to receive from the assets of the Company
in respect of each Exchangeable Share held by such holder on the effective date
(the "Liquidation Date") of such liquidation, dissolution, winding-up or
distribution of assets, before any distribution of any part of the assets of the
Company among the holders of the Common Shares or any other shares ranking
junior to the Exchangeable Shares, an amount per share equal to the Exchangeable
Share Price applicable on the last Business Day prior to the Liquidation Date
(the "Liquidation Amount").

      5.2   On or promptly after the Liquidation Date, and subject to the
exercise by Callco of the Liquidation Call Right, the Company shall cause to be
delivered to the holders of the Exchangeable Shares the Liquidation Amount for
each such Exchangeable Share upon presentation and surrender of the certificates
representing such Exchangeable Shares, together with such other documents and
instruments as may be required to effect a transfer of Exchangeable Shares under
the CBCA and the articles and by-laws of the Company and such additional
documents and instruments as the Transfer Agent and the Company may reasonably
require, at the registered office of the Company or at any office of the
Transfer Agent as may be specified by the Company by notice to the holders of
the Exchangeable Shares. Payment of the total Liquidation Amount for such
Exchangeable Shares shall be made by delivery to each holder, at the address of
the holder recorded in the register of the Company for the Exchangeable Shares
or by holding for pick-up by the holder at the registered office of the Company
or at any office of the Transfer Agent as may be specified by the Company by
notice to the holders of Exchangeable Shares, on behalf of the Company of the
Exchangeable Share Consideration representing the total Liquidation Amount. On
and after the Liquidation Date, the holders of the Exchangeable Shares shall
cease to be holders of such Exchangeable Shares and shall not be entitled to
exercise any of the rights of holders in respect thereof (including any rights
under the Voting and Exchange Trust Agreement), other than the right to receive
their proportionate part of the total Liquidation Amount, unless payment of the
total Liquidation Amount for such Exchangeable Shares shall not be made upon
presentation and surrender of share certificates in accordance with the
foregoing provisions, in which case the rights of the holders shall remain

                                      1-11
<PAGE>

unaffected until the total Liquidation Amount to which such holders are entitled
shall have been paid to such holders in the manner hereinbefore provided. The
Company shall have the right at any time on or after the Liquidation Date to
deposit or cause to be deposited the Exchangeable Share Consideration in respect
of the Exchangeable Shares represented by certificates that have not at the
Liquidation Date been surrendered by the holders thereof in a custodial account
with any chartered bank or trust company in Canada. Upon such deposit being
made, the rights of the holders of Exchangeable Shares, after such deposit,
shall be limited to receiving their proportionate part of the total Liquidation
Amount for such Exchangeable Shares so deposited, against presentation and
surrender of the said certificates held by them, respectively, in accordance
with the foregoing provisions. Upon such payment or deposit of such Exchangeable
Share Consideration, the holders of the Exchangeable Shares shall thereafter be
considered and deemed for all purposes to be holders of the Duke Energy Common
Shares delivered to them or the custodian on their behalf.

      5.3   After the Company has satisfied its obligations to pay the holders
of the Exchangeable Shares the Liquidation Amount per Exchangeable Share
pursuant to Section 5.1 of these share provisions, such holders shall not be
entitled to share in any further distribution of the assets of the Company.

                                   ARTICLE 6

                 RETRACTION OF EXCHANGEABLE SHARES BY HOLDER

      6.1   A holder of Exchangeable Shares shall be entitled at any time,
subject to the exercise by Callco of the Retraction Call Right and otherwise
upon compliance with the provisions of this Article 6, to require the Company to
redeem any or all of the Exchangeable Shares registered in the name of such
holder for an amount per share equal to the Exchangeable Share Price applicable
on the last Business Day prior to the Retraction Date (the "Retraction Price"),
which shall be satisfied in full by the Company causing to be delivered to such
holder the Exchangeable Share Consideration representing the Retraction Price.
To effect such redemption, the holder shall present and surrender at the
registered office of the Company or at any office of the Transfer Agent as may
be specified by the Company by notice to the holders of Exchangeable Shares, the
certificate or certificates representing the Exchangeable Shares which the
holder desires to have the Company redeem, together with such other documents
and instruments as may be required to effect a transfer of Exchangeable Shares
under the CBCA and the articles and bylaws of the Company and such additional
documents and instruments as the Transfer Agent and the Company may reasonably
require, and together with a duly executed statement (the "Retraction Request")
in the form of Schedule A hereto or in such other form as may be acceptable to
the Company:

            (a) specifying that the holder desires to have all or any number
specified therein of the Exchangeable Shares represented by such certificate or
certificates (the "Retracted Shares") redeemed by the Company;

            (b) stating the Business Day on which the holder desires to have the
Company redeem the Retracted Shares (the "Retraction Date"), provided that the
Retraction Date shall be not less than 10 Business Days nor more than 15
Business Days after the date on which the

                                      1-12
<PAGE>

Retraction Request is received by the Company and further provided that, in the
event that no such Business Day is specified by the holder in the Retraction
Request, the Retraction Date shall be deemed to be the 15th Business Day after
the date on which the Retraction Request is received by the Company; and

            (c) acknowledging the overriding right (the "Retraction Call Right")
of Callco to purchase all but not less than all the Retracted Shares directly
from the holder and that the Retraction Request shall be deemed to be a
revocable offer by the holder to sell the Retracted Shares to Callco in
accordance with the Retraction Call Right on the terms and conditions set out in
Section 6.3 below.

      6.2   Subject to the exercise by Callco of the Retraction Call Right, upon
receipt by the Company or the Transfer Agent in the manner specified in Section
6.1 of a certificate or certificates representing the number of Retracted
Shares, together with a Retraction Request and such additional documents and
instruments as the Transfer Agent and the Company may reasonably require, and
provided that the Retraction Request is not revoked by the holder in the manner
specified in Section 6.7, the Company shall redeem the Retracted Shares
effective at the close of business on the Retraction Date and shall cause to be
delivered to such holder the total Retraction Price with respect to such shares
in accordance with Section 6.4. If only a part of the Exchangeable Shares
represented by any certificate is redeemed (or purchased by Callco pursuant to
the Retraction Call Right), a new certificate for the balance of such
Exchangeable Shares shall be issued to the holder at the expense of the Company.

      6.3   Upon receipt by the Company of a Retraction Request, the Company
shall immediately notify Callco thereof and shall provide to Callco a copy of
the Retraction Request. In order to exercise the Retraction Call Right, Callco
must notify the Company of its determination to do so (the "Callco Call Notice")
within five Business Days of notification to Callco by the Company of the
receipt by the Company of the Retraction Request. If Callco does not so notify
the Company within such five Business Day period, the Company will notify the
holder as soon as possible thereafter that Callco will not exercise the
Retraction Call Right. If Callco delivers the Callco Call Notice within such
five Business Day period, and provided that the Retraction Request is not
revoked by the holder in the manner specified in Section 6.7, the Retraction
Request shall thereupon be considered only to be an offer by the holder to sell
all but not less than all the Retracted Shares to Callco in accordance with the
Retraction Call Right. In such event, the Company shall not redeem the Retracted
Shares and Callco shall purchase from such holder and such holder shall sell to
Callco on the Retraction Date all but not less than all the Retracted Shares for
a purchase price (the "Purchase Price") per share equal to the Retraction Price,
which, as set forth in Section 6.4, shall be fully paid and satisfied by the
delivery by or on behalf of Callco, of the Exchangeable Share Consideration
representing the total Purchase Price, whereupon the Company shall have no
obligation to pay the Retraction Price to such holder of Exchangeable Shares so
purchased by Callco. For the purposes of completing a purchase pursuant to the
Retraction Call Right, Callco shall deposit with the Transfer Agent, on or
before the Retraction Date, the Exchangeable Share Consideration representing
the total Purchase Price. Provided that Callco has complied with Section 6.4,
the closing of the purchase and sale of the Retracted Shares pursuant to the
Retraction Call Right shall be deemed to have occurred as at the close of
business on the Retraction Date and, for greater certainty, no redemption by the
Company of such Retracted Shares shall take place on the Retraction Date. In the
event that

                                      1-13
<PAGE>

Callco does not deliver a Callco Call Notice within such five Business Day
period, and provided that the Retraction Request is not revoked by the holder in
the manner specified in Section 6.7, the Company shall redeem the Retracted
Shares on the Retraction Date and in the manner otherwise contemplated in this
Article 6.

      6.4   The Company or Callco, as the case may be, shall deliver or cause
the Transfer Agent to deliver to the relevant holder, at the address of the
holder recorded in the register of the Company for the Exchangeable Shares or at
the address specified in the holder's Retraction Request or by holding for
pick-up by the holder at the registered office of the Company or at any office
of the Transfer Agent as may be specified by the Company by notice to such
holder of Exchangeable Shares, the Exchangeable Share Consideration representing
the total Retraction Price or the total Purchase Price, as the case may be, and
such delivery of such Exchangeable Share Consideration to the Transfer Agent
shall be deemed to be payment of and shall satisfy and discharge all liability
for the total Retraction Price or total Purchase Price, as the case may be, to
the extent that the same is represented by such Exchangeable Share
Consideration.

      6.5   On and after the close of business on the Retraction Date, the
holder of the Retracted Shares shall cease to be a holder of such Retracted
Shares and shall not be entitled to exercise any of the rights of a holder in
respect thereof, other than the right to receive the total Retraction Price or
total Purchase Price, as the case may be, unless upon presentation and surrender
of certificates in accordance with the foregoing provisions, payment of the
total Retraction Price or the total Purchase Price, as the case may be, shall
not be made as provided in Section 6.4, in which case the rights of such holder
shall remain unaffected until the total Retraction Price or the total Purchase
Price, as the case may be, has been paid in the manner hereinbefore provided. On
and after the close of business on the Retraction Date, provided that
presentation and surrender of certificates and payment of the total Retraction
Price or the total Purchase Price, as the case may be, has been made in
accordance with the foregoing provisions, the holder of the Retracted Shares so
redeemed by the Company or purchased by Callco shall thereafter be considered
and deemed for all purposes to be the holder of the Duke Energy Common Shares
delivered to it.

      6.6   Notwithstanding any other provision of this Article 6, the Company
shall not be obligated to redeem Retracted Shares specified by a holder in a
Retraction Request to the extent that such redemption of Retracted Shares would
be contrary to solvency requirements or other provisions of applicable law. If
the Company believes that on any Retraction Date it would not be permitted by
any of such provisions to redeem the Retracted Shares tendered for redemption on
such date, and provided that Callco shall not have exercised the Retraction Call
Right with respect to the Retracted Shares, the Company shall only be obligated
to redeem Retracted Shares specified by a holder in a Retraction Request to the
extent of the maximum number that may be so redeemed (rounded down to a whole
number of shares) as would not be contrary to such provisions and shall notify
the holder at least two Business Days prior to the Retraction Date as to the
number of Retracted Shares which will not be redeemed by the Company. In any
case in which the redemption by the Company of Retracted Shares would be
contrary to solvency requirements or other provisions of applicable law, the
Company shall redeem the maximum number of Exchangeable Shares which the Board
of Directors determines the Company is permitted to redeem as of the Retraction
Date on a pro rata basis and shall issue to each holder of Retracted Shares a
new certificate, at the expense of the Company, representing the Retracted

                                      1-14
<PAGE>

Shares not redeemed by the Company pursuant to Section 6.2. Provided that the
Retraction Request is not revoked by the holder in the manner specified in
Section 6.7 and Callco does not exercise the Retraction Call Right, the holder
of any such Retracted Shares not redeemed by the Company pursuant to Section 6.2
as a result of solvency requirements or other provisions of applicable law shall
be deemed by giving the Retraction Request to have instructed the Trustee to
require Duke Energy to purchase such Retracted Shares from such holder on the
Retraction Date or as soon as practicable thereafter on payment by Duke Energy
to such holder of the Retraction Price for each such Retracted Share, all as
more specifically provided in the Voting and Exchange Trust Agreement.

      6.7   A holder of Retracted Shares may, by notice in writing given by the
holder to the Company before the close of business on the Business Day
immediately preceding the Retraction Date, withdraw its Retraction Request, in
which event such Retraction Request shall be null and void and, for greater
certainty, the revocable offer constituted by the Retraction Request to sell the
Retracted Shares to Callco shall be deemed to have been revoked.

                                   ARTICLE 7

                REDEMPTION OF EXCHANGEABLE SHARES BY THE COMPANY

      7.1   Subject to applicable law, and provided Callco has not exercised the
Redemption Call Right, the Company shall on the Redemption Date redeem all but
not less than all of the then outstanding Exchangeable Shares for an amount per
share equal to the Exchangeable Share Price applicable on the last Business Day
prior to the Redemption Date (the "Redemption Price").

      7.2   In any case of a redemption of Exchangeable Shares under this
Article 7, the Company shall, at least 45 days before the Redemption Date (other
than a Redemption Date established in connection with a Duke Energy Control
Transaction, an Exchangeable Share Voting Event, an Exempt Exchangeable Share
Voting Event or a Distribution Date), send or cause to be sent to each holder of
Exchangeable Shares a notice in writing of the redemption by the Company or the
purchase by Callco under the Redemption Call Right, as the case may be, of the
Exchangeable Shares held by such holder. In the case of a Redemption Date
established in connection with a Duke Energy Control Transaction, an
Exchangeable Share Voting Event, an Exempt Exchangeable Share Voting Event or a
Distribution Date, the written notice of redemption by the Company or the
purchase by Callco under the Redemption Call Right will be sent on or before the
Redemption Date, on as many days prior written notice as may be determined by
the Board of Directors to be reasonably practicable in the circumstances. In any
such case, such notice shall set out the formula for determining the Redemption
Price or the Redemption Call Purchase Price, as the case may be, the Redemption
Date and, if applicable, particulars of the Redemption Call Right. In the case
of any notice given in connection with a possible Redemption Date, such notice
will be given contingently and will be withdrawn if the contingency does not
occur.

      7.3   On or after the Redemption Date and subject to the exercise by
Callco of the Redemption Call Right, the Company shall cause to be delivered to
the holders of the Exchangeable Shares to be redeemed the Redemption Price for
each such Exchangeable Share

                                      1-15
<PAGE>

upon presentation and surrender at the registered office of the Company or at
any office of the Transfer Agent as may be specified by the Company in the
notice described in Section 7.2 of the certificates representing such
Exchangeable Shares, together with such other documents and instruments as may
be required to effect a transfer of Exchangeable Shares under the CBCA and the
articles and by-laws of the Company and such additional documents and
instruments as the Transfer Agent and the Company may reasonably require.
Payment of the total Redemption Price for such Exchangeable Shares shall be made
by delivery to each holder, at the address of the holder recorded in the
securities register of the Company or by holding for pick-up by the holder at
the registered office of the Company or at any office of the Transfer Agent as
may be specified by the Company in such notice, on behalf of the Company of the
Exchangeable Share Consideration representing the total Redemption Price. On and
after the Redemption Date, the holders of the Exchangeable Shares called for
redemption shall cease to be holders of such Exchangeable Shares and shall not
be entitled to exercise any of the rights of holders in respect thereof, other
than the right to receive their proportionate part of the total Redemption
Price, unless payment of the total Redemption Price for such Exchangeable Shares
shall not be made upon presentation and surrender of certificates in accordance
with the foregoing provisions, in which case the rights of the holders shall
remain unaffected until the total Redemption Price has been paid in the manner
hereinbefore provided. The Company shall have the right at any time after the
sending of notice of its intention to redeem the Exchangeable Shares as
aforesaid to deposit or cause to be deposited the Exchangeable Share
Consideration with respect to the Exchangeable Shares so called for redemption,
or of such of the said Exchangeable Shares represented by certificates that have
not at the date of such deposit been surrendered by the holders thereof in
connection with such redemption, in a custodial account with any chartered bank
or trust company in Canada named in such notice. Upon the later of such deposit
being made and the Redemption Date, the Exchangeable Shares in respect whereof
such deposit shall have been made shall be redeemed and the rights of the
holders thereof after such deposit or Redemption Date, as the case may be, shall
be limited to receiving their proportionate part of the total Redemption Price
for such Exchangeable Shares so deposited, against presentation and surrender of
the said certificates held by them, respectively, in accordance with the
foregoing provisions. Upon such payment or deposit of such Exchangeable Share
Consideration, the holders of the Exchangeable Shares shall thereafter be
considered and deemed for all purposes to be holders of the Duke Energy Common
Shares delivered to them or the custodian on their behalf; provided that in the
case of a Redemption Date established in connection with a Distribution Date,
the holders of Exchangeable Shares shall be considered and deemed for the
purposes of the Duke Energy Rights Agreement to be and treated as record holders
of Duke Energy Common Shares on and after the Redemption Date, regardless of
when such payment or deposit of such Exchangeable Share Consideration is made.

<PAGE>

      8.1   Subject to applicable law and the articles of the Company and
notwithstanding Section 8.2, the Company may at any time and from time to time
purchase for cancellation all or any part of the Exchangeable Shares by private
agreement with any holder of Exchangeable Shares.

      8.2   Subject to applicable law and the articles of the Company, the
Company may at any time and from time to time purchase for cancellation all or
any part of the outstanding Exchangeable Shares by tender to all the holders of
record of Exchangeable Shares then outstanding or through the facilities of any
stock exchange on which the Exchangeable Shares are listed or quoted at any
price per share together with an amount equal to all declared and unpaid
dividends thereon for which the record date has occurred prior to the date of
purchase. If in response to an invitation for tenders under the provisions of
this Section 8.2, more Exchangeable Shares are tendered at a price or prices
acceptable to the Company than the Company is prepared to purchase, the
Exchangeable Shares to be purchased by the Company shall be purchased as nearly
as may be pro rata according to the number of shares tendered by each holder who
submits a tender to the Company, provided that when shares are tendered at
different prices, the pro rating shall be effected (disregarding fractions) only
with respect to the shares tendered at the price at which more shares were
tendered than the Company is prepared to purchase after the Company has
purchased all the shares tendered at lower prices. If only part of the
Exchangeable Shares represented by any certificate shall be purchased, a new
certificate for the balance of such shares shall be issued at the expense of the
Company.

and Section 12.2, the holders of the Exchangeable Shares shall not be entitled
as such to receive notice of or to attend any meeting of the shareholders of the
Company or to vote at any such meeting.

      10.2  Any approval given by the holders of the Exchangeable Shares to add
to, change or remove any right, privilege, restriction or condition attaching to
the Exchangeable Shares or any other matter requiring the approval or consent of
the holders of the Exchangeable Shares shall be deemed to have been sufficiently
given if it shall have been given in accordance with applicable law subject to a
minimum requirement that such approval be evidenced by resolution passed by not
less than 66 2/3% of the votes cast on such resolution by holders represented in
person or by proxy at a meeting of holders of Exchangeable Shares duly called
and held at which the holders of at least 25% of the outstanding Exchangeable
Shares at that time are present or represented by proxy; provided that if at any
such meeting the holders of at least 25% of the outstanding Exchangeable Shares
at that time are not present or represented by proxy within one-

                                      1-17

half hour after the time appointed for such meeting, then the meeting shall be
adjourned to such date not less than five days thereafter and to such time and
place as may be designated by the Chair of such meeting. At such adjourned
meeting, the holders of Exchangeable Shares present or represented by proxy
thereat may transact the business for which the meeting was originally called
and a resolution passed thereat by the affirmative vote of not less than 66 2/3%
of the votes cast on such resolution by holders represented in person or by
proxy at such meeting shall constitute the approval or consent of the holders of
the Exchangeable Shares. For purposes of this section, any spoiled votes,
illegible votes, defective votes and abstentions shall be deemed to be votes not
cast.

                     RECIPROCAL CHANGES, ETC. IN RESPECT OF
                            DUKE ENERGY COMMON SHARES

      11.1  Each holder of an Exchangeable Share acknowledges that the Support
Agreement provides, in part, that Duke Energy will not, without the prior
approval of the Company and the prior approval of the holders of the
Exchangeable Shares given in accordance with Section 10.2 of these share
provisions:

            (a) issue or distribute Duke Energy Common Shares (or securities
exchangeable for or convertible into or carrying rights to acquire Duke Energy
Common Shares) to the holders of all or substantially all of the then
outstanding Duke Energy Common Shares by way of stock dividend or other
distribution, other than an issue of Duke Energy Common Shares (or securities
exchangeable for or convertible into or carrying rights to acquire Duke Energy
Common Shares) to holders of Duke Energy Common Shares who (i) exercise an
option to receive dividends in Duke Energy Common Shares (or securities
exchangeable for or convertible into or carrying rights to acquire Duke Energy
Common Shares) in lieu of receiving cash dividends, or (ii) pursuant to any
dividend reinvestment plan or scrip dividend;

            (b) issue or distribute rights, options or warrants to the holders

entitling them to subscribe for or to purchase Duke Energy Common Shares (or

            (c) issue or distribute to the holders of all or substantially all
of the then outstanding Duke Energy Common Shares:

                  (i) shares or securities of Duke Energy of any class other
than Duke Energy Common Shares (other than shares convertible into or
exchangeable for or carrying rights to acquire Duke Energy Common Shares);

                  (ii) rights, options or warrants other than those referred to
in Section 11.1(b) above;

                  (iii) evidences of indebtedness of Duke Energy; or

change is permitted under applicable law. The Support Agreement further
provides, in part, that the aforesaid provisions of the Support Agreement shall
not be changed without the approval of the holders of the Exchangeable Shares
given in accordance with Section 10.2.

                 ACTIONS BY THE COMPANY UNDER SUPPORT AGREEMENT

provisions of the Support Agreement and the Voting Trust and Exchange Agreement
applicable to Duke Energy, Callco and the Company, respectively, in accordance
with the terms thereof including taking all such actions and doing all such
things as shall be necessary or advisable to enforce to the fullest extent
possible for the direct benefit of the Company all rights and benefits in favour
of the Company under or pursuant thereto.

      12.2  The Company shall not propose, agree to or otherwise give effect to
any amendment to, or waiver or forgiveness of its rights or obligations under,
the Support Agreement or the Voting Trust and Exchange Agreement without the
approval of the holders of the Exchangeable Shares given in accordance with

questions arising thereunder which, in the good faith opinion of the Board of
Directors, it may be expedient to make, provided that the Board of Directors
shall be of the good faith opinion, after consultation with counsel, that such
provisions and modifications will not be prejudicial to the interests of the
holders of the Exchangeable Shares; or

            (c) making such changes in or corrections to such agreement which,
on the advice of counsel to the Company, are required for the purpose of curing
or correcting any ambiguity or defect or inconsistent provision or clerical

                     LEGEND; CALL RIGHTS; WITHHOLDING RIGHTS

      13.1  The certificates evidencing the Exchangeable Shares shall contain or
have affixed thereto a legend in form and on terms approved by the Board of
Directors, with respect to the Support Agreement, the provisions of the Plan of
Arrangement relating to the Liquidation Call Right and the Redemption Call
Right, and the Voting and Exchange Trust Agreement (including the provisions
with respect to the voting rights, exchange right and automatic exchange
thereunder) and the Retraction Call Right.

      13.2  Each holder of an Exchangeable Share, whether of record or
beneficial, by virtue of becoming and being such a holder shall be deemed to
acknowledge each of the Liquidation Call Right, the Retraction Call Right and
the Redemption Call Right, in each case, in favour of Callco, and the overriding
nature thereof in connection with the liquidation, dissolution or winding-up of
the Company or any other distribution of the assets of the Company among its
shareholders for the purpose of winding-up its affairs, or the retraction or
redemption of Exchangeable Shares, as the case may be, and to be bound thereby
in favour of Callco as therein provided.

      13.3  The Company, Callco, Duke Energy and the Transfer Agent shall be
entitled to deduct and withhold from any dividend or consideration otherwise
payable to any holder of Exchangeable Shares such amounts as the Company,
Callco, Duke Energy or the Transfer Agent is required to deduct and withhold
with respect to such payment under the Income Tax Act (Canada), the United
States Internal Revenue Code of 1986 or any provision of provincial, state,
territorial, local or foreign tax law, in each case, as amended. To the extent
that amounts are so withheld, such withheld amounts shall be treated for all
purposes hereof as having been paid to the holder of the Exchangeable Shares in
respect of which such deduction and withholding was made, provided that such
withheld amounts are actually remitted to the appropriate taxing authority. To
the extent that the amount so required or permitted to be deducted or withheld
from any payment to a holder exceeds the cash portion of the consideration
otherwise payable to the holder, the Company, Callco, Duke Energy and the
Transfer Agent are hereby authorized to sell or otherwise dispose of such
portion of the consideration as is necessary to provide sufficient

                                      1-20

funds to the Company, Callco, Duke Energy or the Transfer Agent, as the case may
be, to enable it to comply with such deduction or withholding requirement and
the Company, Callco, Duke Energy or the Transfer Agent shall notify the holder
thereof and remit any unapplied balance of the net proceeds of such sale.

      14.2  Any presentation and surrender by a holder of Exchangeable Shares
to the Company or the Transfer Agent of certificates representing Exchangeable
Shares in connection with the liquidation, dissolution or winding-up of the

registered mail (postage prepaid) or by delivery to the registered office of the
Company or to such office of the Transfer Agent as may be specified by the
Company, in each case, addressed to the attention of the Secretary of the
Company. Any such presentation and surrender of certificates shall only be

or otherwise alter or affect any action or proceeding intended to be taken by
the Company pursuant thereto.

      14.4  Subject to the requirements of National Policy Statement 41 and any
successor policy statement or rule of the Canadian Securities Administrators or
other applicable law, for greater certainty, the Company shall not be required

hereof, give such notice by means of publication in The Globe and Mail; national

circulation in Canada and in a French language daily newspaper of general
circulation in the Province of Quebec, once in each of two successive weeks, and
notice so published shall be deemed to have been given on the latest date on

threatened interruption of mail service due to strike, lock-out or otherwise,
any notice to be given to the Company would be unlikely to reach its destination
in a timely manner, such notice shall be valid and effective only if delivered
personally to the Company in accordance with Section 14.1 or 14.2, as the case
may be.

                               RETRACTION REQUEST

              [TO BE PRINTED ON EXCHANGEABLE SHARE CERTIFICATES]

To 3946509 Canada Inc. ("Exchangeco") and 3058368 Nova Scotia Company ("Callco")

      This notice is given pursuant to Article 6 of the rights, privileges,

      The undersigned hereby notifies Exchangeco that, subject to the Retraction

         specified above, the Retraction Date shall be deemed to be the 15th
         Business Day after the date on which this notice is received by

      The undersigned acknowledges the overriding Retraction Call Right of
Callco to purchase all but not less than all the Retracted Shares from the

purchase the unredeemed Retracted Shares.

            Energy of any dividend on Duke Energy Common Shares and take all
            such other actions as are reasonably necessary, in cooperation with
            Exchangeco, to ensure that (i) the respective declaration date,
            record date and payment date for an Equivalent Dividend on the
            Exchangeable Shares shall be the same as the declaration date,
            record date and payment date for the corresponding dividend on the
            Duke Energy Common Shares, or (ii) the record date and effective
            date for an Equivalent Stock Subdivision shall be the same as the
            record date and payment date for the stock dividend on the Duke

      (c)   ensure that the record date for any dividend declared on Duke Energy

            Amount, the Retraction Price or the Redemption Price in respect of
            each issued and outstanding Exchangeable Share (other than
            Exchangeable Shares owned by Duke Energy or its Affiliates) upon the
            liquidation, dissolution or winding-up of Exchangeco or any other
            distribution of the assets of Exchangeco among its shareholders for
            the purpose of winding-up its affairs, the delivery of a Retraction
            Request by a holder of Exchangeable Shares or a redemption of
            Exchangeable Shares by Exchangeco, as the case may be, including all
            such actions and all such things as are necessary or desirable to
            enable and permit Exchangeco to cause to be delivered Duke Energy
            Common Shares to the holders of Exchangeable Shares in accordance
            with the provisions of Article 5, 6 or 7, as the case may be, of the

            Redemption Call Right, as the case may be.

2.2   Segregation of Funds

      Duke Energy will cause Exchangeco to deposit a sufficient amount of funds

outstanding, keep available, free from preemptive and other rights, out of its
authorized and unissued capital stock such number of Duke Energy Common Shares
(or other shares or securities into which Duke Energy Common Shares may be
reclassified or changed as contemplated by Section 2.7 hereof) (a) as is equal

            Arrangement).

2.5   Delivery of Duke Energy Common Shares to Exchangeco and Callco

      In furtherance of its obligations under Sections 2.1(d) and (e) hereof,
upon notice from Exchangeco or Callco of any event that requires Exchangeco or

Exchangeable Shares, Duke Energy shall forthwith issue and deliver the requisite
number of Duke Energy Common Shares to be received by, and issued to or to the

such Duke Energy Common Share.

2.6   Qualification of Duke Energy Common Shares

      Duke Energy covenants that if any Duke Energy Common Shares (or other
shares or securities into which Duke Energy Common Shares may be reclassified or
changed as contemplated by Section 2.7 hereof) (other than Duke Energy Common
Shares held by the Trustee) to be issued and delivered hereunder (including for
greater certainty, pursuant to the Exchangeable Share Provisions, or pursuant to
the Exchange Right or the Automatic Exchange Rights (all as defined in the
Voting and Exchange Trust Agreement)) require registration or qualification
with, or approval of, or the filing of any document, including any prospectus or

Common Shares may be reclassified or changed as contemplated by Section 2.7
hereof) may be issued and delivered by Duke Energy at the direction of
Exchangeco or Callco, if applicable, to the holder of surrendered Exchangeable
Shares or in order that such shares (or other shares or securities into which
Duke Energy Common Shares may be reclassified or changed as contemplated by
Section 2.7 hereof) may be freely traded thereafter (other than any restrictions
of general application on transfer by reason of a holder being a "control
person" of Duke Energy for purposes of Canadian provincial securities law or an
"affiliate" of Duke Energy for purposes of United States federal or state
securities law), Duke Energy will use its reasonable best efforts and in good
faith expeditiously take all such actions and do all such things as are
necessary or desirable and within its power to cause such Duke Energy Common
Shares (or other shares or securities into which Duke Energy Common Shares may
be reclassified or changed as contemplated by Section 2.7 hereof) to be and
remain duly registered, qualified or approved under United States and/or
Canadian law, as the case may be, to the extent expressly provided in the
Combination Agreement. Duke Energy will use its reasonable best efforts and in
good faith expeditiously take all such actions and do all

                                      -5-
<PAGE>

such things as are reasonably necessary or desirable to cause all Duke Energy
Common Shares (or other shares or securities into which Duke Energy Common
Shares may be reclassified or changed as contemplated by Section 2.7 hereof)
(other than Duke Energy Common Shares held by the Trustee) to be delivered
hereunder to be listed, quoted or posted for trading on all stock exchanges and
quotation systems on which outstanding Duke Energy Common Shares (or other

                  substantially all of the then outstanding Duke Energy Common

                  exchangeable for or convertible into or carrying rights to
                  acquire Duke Energy Common Shares) to holders of Duke Energy
                  Common Shares who (A) exercise an option to receive dividends
                  in Duke Energy Common Shares (or securities exchangeable for
                  or convertible into or carrying rights to acquire Duke Energy
                  Common Shares) in lieu of receiving cash dividends, or (B)

                  Common Shares), (B) rights, options or warrants other than
                  those referred to in Section 2.7(a)(ii) above, (C) evidences
                  of indebtedness of Duke Energy or (D) assets of Duke Energy,

                  unless the economic equivalent on a per share basis of such
                  rights, options, warrants, securities, shares, evidences of
                  indebtedness or other assets is issued or distributed
                  simultaneously to holders of the Exchangeable Shares.

      (b)   Duke Energy will not without the prior approval of Exchangeco and
            the prior approval of the holders of the Exchangeable Shares given
            in accordance with Section 10.2 of the Exchangeable Share
            Provisions:

            (i)   subdivide, redivide or change the then outstanding Duke Energy
                  Common Shares into a greater number of Duke Energy Common
                  Shares; or

            (ii)  reduce, combine, consolidate or change the then outstanding
                  Duke Energy Common Shares into a lesser number of Duke Energy
                  Common Shares; or

            (iii) reclassify or otherwise change Duke Energy Common Shares or
                  effect an amalgamation, merger, reorganization or other
                  transaction affecting the Duke Energy Common Shares,

                  unless the same or an economically equivalent change shall
                  simultaneously be made to, or in the rights of the holders of,
                  the Exchangeable Shares.

      (c)   Duke Energy will ensure that the record date for any event referred
            to in Section 2.7(a) or 2.7(b) above, or (if no record date is
            applicable for such event) the effective date for any such event, is
            not less than five Business Days after the date on which such event
            is declared or announced by Duke Energy (with contemporaneous
            notification thereof by Duke Energy to Exchangeco).

      (d)   The Board of Directors of Exchangeco shall determine, in good faith
            and in its sole discretion, economic equivalence for the purposes of
            any event referred to in Section 2.7(a) or 2.7(b) above and each
            such determination shall be conclusive and binding on Duke Energy.
            In making each such determination, the following factors shall,
            without excluding other factors determined by the Board of Directors
            of Exchangeco to be relevant, be considered by the Board of
            Directors of Exchangeco:

            (i)   in the case of any stock dividend or other distribution
                  payable in Duke Energy Common Shares, the number of such
                  shares issued in proportion to the number of Duke Energy
                  Common Shares previously outstanding;

            (ii)  in the case of the issuance or distribution of any rights,
                  options or warrants to subscribe for or purchase Duke Energy
                  Common Shares (or securities exchangeable for or convertible
                  into or carrying rights to acquire Duke Energy Common Shares),
                  the relationship between the exercise price of each such
                  right, option or warrant and the Current Market Price;

            (iii) in the case of the issuance or distribution of any other form
                  of property (including any shares or securities of Duke Energy
                  of any class other than Duke Energy Common Shares, any rights,
                  options or warrants other than those referred to in Section
                  2.7(d)(ii) above, any evidences of indebtedness of Duke Energy
                  or any assets of Duke Energy), the relationship between the
                  fair market value (as determined by the Board of Directors of
                  Exchangeco in the manner above contemplated) of such property
                  to be issued or distributed with respect to each outstanding
                  Duke Energy Common Share and the Current Market Price;

                                      -7-
<PAGE>

            (iv)  in the case of any subdivision, redivision or change of the
                  then outstanding Duke Energy Common Shares into a greater
                  number of Duke Energy Common Shares or the reduction,
                  combination, consolidation or change of the then outstanding
                  Duke Energy Common Shares into a lesser number of Duke Energy
                  Common Shares or any amalgamation, merger, reorganization or
                  other transaction affecting Duke Energy Common Shares, the
                  effect thereof upon the then outstanding Duke Energy Common
                  Shares; and

            (v)   in all such cases, the general taxation consequences of the
                  relevant event to holders of Exchangeable Shares to the extent
                  that such consequences may differ from the taxation
                  consequences to holders of Duke Energy Common Shares as a
                  result of differences between taxation laws of Canada and the
                  United States (except for any differing consequences arising
                  as a result of differing marginal taxation rates and without
                  regard to the individual circumstances of holders of
                  Exchangeable Shares).

      (e)   Exchangeco agrees that, to the extent required, upon due notice from
            Duke Energy, Exchangeco will use its best efforts to take or cause
            to be taken such steps as may be necessary for the purposes of
            ensuring that appropriate dividends are paid or other distributions
            are made by Exchangeco, or subdivisions, redivisions or changes are
            made to the Exchangeable Shares, in order to implement the required
            economic equivalent with respect to the Duke Energy Common Shares
            and Exchangeable Shares as provided for in this Section 2.7.

2.8   Tender Offers

      In the event that a tender offer, share exchange offer, issuer bid,
take-over bid or similar transaction with respect to Duke Energy Common Shares
(an "Offer") is proposed by Duke Energy or is proposed to Duke Energy or its
shareholders and is recommended by the Board of Directors of Duke Energy, or is
otherwise effected or to be effected with the consent or approval of the Board
of Directors of Duke Energy, and the Exchangeable Shares are not redeemed by
Exchangeco or purchased by Callco pursuant to the Redemption Call Right, Duke
Energy will use its reasonable best efforts expeditiously and in good faith to
take all such actions and do all such things as are necessary or desirable to
enable and permit holders of Exchangeable Shares (other than Duke Energy and its
Affiliates) to participate in such Offer to the same extent and on an
economically equivalent basis as the holders of Duke Energy Common Shares,
without discrimination. Without limiting the generality of the foregoing, Duke
Energy will use its reasonable best efforts expeditiously and in good faith to
ensure that holders of Exchangeable Shares may participate in each such Offer
without being required to retract Exchangeable Shares as against Exchangeco (or,
if so required, to ensure that any such retraction, shall be effective only
upon, and shall be conditional upon, the closing of such Offer and only to the
extent necessary to tender or deposit to the Offer). Nothing herein shall affect
the rights of Exchangeco to redeem (or Callco to purchase pursuant to the
Redemption Call Right) Exchangeable Shares, as applicable, in the event of a
Duke Energy Control Transaction.

Exchangeco that, as long as any outstanding Exchangeable Shares are owned by any
Person other than Duke Energy or any of its Affiliates, Duke Energy will be and
remain the direct or indirect beneficial owner of all issued and outstanding
voting shares in the capital of Exchangeco and Callco. Notwithstanding the
foregoing, Duke Energy shall not be in violation of this section if any person

all of the assets of Duke Energy or the Duke Energy Common Shares pursuant to
any merger of Duke Energy pursuant to which Duke Energy was not the surviving

its Affiliates for the sole purpose of attending each meeting of holders of
Exchangeable Shares in order to be counted as part of the quorum for each such
meeting. Duke Energy further covenants and agrees that it will not, and will
cause its Affiliates not to, exercise any voting rights which may be exercisable
by holders of Exchangeable Shares from time to time pursuant to the Exchangeable
Share Provisions or pursuant to the provisions of the CBCA (or any successor or
other corporate statute by which Exchangeco may in the future be governed) with
respect to any Exchangeable Shares held by it or by its Affiliates in respect of
any matter considered at any meeting of holders of Exchangeable Shares.

2.11  Rule l0b-18 Purchases

      For greater certainty, nothing contained in this Agreement, including the
obligations of Duke Energy contained in Section 2.8 hereof, shall limit the
ability of Duke Energy or Exchangeco to make a "Rule 10b-18 purchase" of Duke
Energy Common Shares pursuant to Rule 10b-18 of the United States Securities
Exchange Act of 1934, as amended, or any successor rule.

2.12  Stock Exchange Listing

      Duke Energy covenants and agrees in favour of Exchangeco that, as long as
any outstanding Exchangeable Shares are owned by any Person other than Duke
Energy or any of its Affiliates, Duke Energy will use its reasonable best
efforts to maintain a listing for such Exchangeable Shares on a Canadian stock
exchange.

case, are to be distributed from time to time to holders of Duke Energy Common

each Beneficiary, at the expense of Duke Energy, copies of all such materials
received by the Trustee from Duke Energy. The Trustee will also make available
for inspection by any Beneficiary at the Trustee's principal office in Lakewood,
Colorado copies of all such materials. Notwithstanding the foregoing, Duke
Energy at its option may exercise the duties of the Trustee to deliver copies of
all such materials to each Beneficiary as required by this Section 4.5 so long
as in each case Duke Energy delivers a certificate to the Trustee stating that
Duke Energy has undertaken to perform the obligations set forth in this Section
4.5.

      Exchangeco shall, (a) prior to each annual and special Duke Energy Meeting

made at any time by the Trustee in writing, prepare or cause to be prepared a
list (a "List") of the names and addresses of the Beneficiaries arranged in
alphabetical order and showing the number of Exchangeable Shares held of record

event within sufficient time as to permit the Trustee to perform its obligations
under this Agreement. Duke Energy agrees to give Exchangeco notice (with a copy
to the Trustee) of the calling of any Duke Energy Meeting or the seeking of any
Duke Energy Consent by Duke Energy or its management, together with the record

            representative shall sign and deliver to such Beneficiary (or its

            meeting or (ii) submits to such representative written revocation of
            any such previous instructions. At such meeting, upon receipt of a

manner of communications is reasonably available to the Trustee) to each
Beneficiary at its address as shown on the books of Exchangeco. Duke Energy
agrees not to communicate with holders of Duke Energy Common Shares with respect

deliver copies of materials to each Beneficiary and Exchangeco provides the
required information and materials to Duke Energy.

Right"), upon the occurrence and during the continuance of an Insolvency Event,
to require Duke Energy to purchase from each or any Beneficiary all or any part

hereby acknowledges receipt from the Trustee as trustee for and on behalf of the

            Right or the Automatic Exchange Rights, and the Trustee shall not

      5.2   Legended Share Certificates

      Exchangeco will cause each certificate representing Exchangeable Shares to

            the Exchange Right in respect of the Exchangeable Shares held by a
            Beneficiary; and

      (b)   the Automatic Exchange Rights.

      5.3   General Exercise of Exchange Right

      The Exchange Right shall be and remain vested in and exercisable by the
Trustee. Subject to Section 6.15, the Trustee shall exercise the Exchange Right
only on the basis of instructions received pursuant to this Article 5 from
Beneficiaries entitled to instruct the Trustee as to the exercise thereof. To
the extent that no instructions are received from a Beneficiary with respect to

Exchange Right.

      The purchase price payable by Duke Energy for each Exchangeable Share to
be purchased by Duke Energy under the Exchange Right shall be an amount per

Exchangeable Share Price for each such Exchangeable Share so purchased may be
satisfied only by Duke Energy delivering or causing to be delivered to the
Trustee, on behalf of the relevant Beneficiary, the Exchangeable Share
Consideration representing the total Exchangeable Share Price. Upon payment by
Duke Energy of such purchase price to the Trustee for the benefit of the
Beneficiary, the relevant Beneficiary shall cease to have any right to be paid
any amount in respect of declared and unpaid dividends on each such Exchangeable
Share by Exchangeco.

Exchangeco and Duke Energy may reasonably require together with (a) a duly
completed form of notice of exercise of the Exchange Right, contained on the
reverse of or attached to the Exchangeable Share certificates, stating (i) that
the Beneficiary thereby instructs the Trustee to exercise the Exchange Right so
as to require Duke Energy to purchase from the Beneficiary the number of
Exchangeable Shares specified therein, (ii) that such Beneficiary has good title
to and owns all such Exchangeable Shares to be acquired by Duke Energy free and
clear of all liens, claims, security interests and encumbrances, (iii) the names
in which the certificates representing Duke Energy Common Shares issuable in
connection with the exercise of the Exchange Right are to be issued and (iv) the
names and addresses of the persons to whom such new certificates should be
delivered, and (b) payment (or evidence satisfactory to the Trustee, Exchangeco
and Duke Energy of payment) of the taxes (if any) payable as contemplated by
Section 5.8 of this Agreement. If only a part of the Exchangeable Shares
represented by any certificate or certificates delivered to the Trustee are to
be purchased by Duke Energy under the Exchange Right, a new certificate for the
balance of such Exchangeable Shares shall be issued to the holder at the expense
of Exchangeco.

      5.6   Delivery of Duke Energy Common Shares; Effect of Exercise

      Promptly after the receipt by the Trustee of the certificates representing
the Exchangeable Shares which the Beneficiary desires Duke Energy to purchase
under the Exchange Right, together with such documents and instruments of
transfer and a duly completed form of notice of exercise of the Exchange Right
(and payment of taxes, if any payable as contemplated by Section 5.8 or evidence
thereof), duly endorsed for transfer to Duke Energy, the Trustee shall notify
Duke Energy and Exchangeco of its receipt of the same, which notice to Duke
Energy and Exchangeco shall constitute exercise of the Exchange Right by the
Trustee on behalf of the Beneficiary in respect of such Exchangeable Shares, and
Duke Energy shall promptly thereafter deliver or cause to be delivered to the
Trustee, for delivery to the Beneficiary in respect of such Exchangeable Shares
(or to such other persons, if any, properly designated by such Beneficiary) the
Exchangeable Share Consideration deliverable in connection with the exercise of
the Exchange Right; provided, however, that no such delivery shall be made
unless and until the Beneficiary requesting the same shall have paid (or
provided evidence satisfactory to the Trustee, Exchangeco and Duke Energy of the
payment of) the taxes (if any) payable as contemplated by Section 5.8 of this
Agreement. Immediately upon the giving of notice by the Trustee to Duke Energy
and Exchangeco of the exercise of the Exchange Right, as provided in this
Section 5.6, the closing of the transaction of purchase and sale contemplated by
the Exchange Right shall be deemed to have occurred, and the Beneficiary of such
Exchangeable Shares shall be deemed to have transferred to Duke Energy all of
such Beneficiary's right, title and interest in and to such Exchangeable Shares
and in the related interest in the Trust Estate and shall cease to be a holder
of such Exchangeable Shares and shall not be entitled to exercise any of the
rights of a holder in respect thereof, other than the right to receive his
proportionate part of the total purchase price therefor, unless such
Exchangeable Share Consideration is not delivered by Duke Energy to the Trustee
for delivery to such Beneficiary (or to such other person, if any, properly
designated by such Beneficiary) within five Business Days of the date of the
giving of such notice by the Trustee, in which case the rights of the
Beneficiary shall remain unaffected until such Exchangeable Share Consideration
is delivered by Duke Energy and any cheque included therein is paid. Upon
delivery of such Exchangeable Share Consideration by Duke Energy to the Trustee,
the Trustee shall deliver such Exchangeable Share Consideration to such
Beneficiary (or

                                      -14-
                      VOTING AND EXCHANGE TRUST AGREEMENT
<PAGE>

to such other person, if any, properly designated by such Beneficiary).
Concurrently with such Beneficiary ceasing to be a holder of Exchangeable
Shares, the Beneficiary shall be considered and deemed for all purposes to be
the holder of the Duke Energy Common Shares delivered to it pursuant to the
Exchange Right.

      5.7   Exercise of Exchange Right Subsequent to Retraction

      In the event that a Beneficiary has exercised its right under Article 6 of
the Exchangeable Share Provisions to require Exchangeco to redeem any or all of
the Exchangeable Shares held by the Beneficiary (the "Retracted Shares") and is
notified by Exchangeco pursuant to Section 6.6 of the Exchangeable Share
Provisions that Exchangeco will not be permitted as a result of solvency
requirements of applicable law to redeem all such Retracted Shares, and provided
that Callco shall not have exercised the Retraction Call Right with respect to
the Retracted Shares and that the Beneficiary has not revoked the retraction
request delivered by the Beneficiary to Exchangeco pursuant to Section 6.7 of
the Exchangeable Share Provisions, and provided further that the Trustee has
received written notice of same from Exchangeco or Duke Energy, the retraction
request will constitute and will be deemed to constitute notice from the
Beneficiary to the Trustee instructing the Trustee to exercise the Exchange
Right with respect to those Retracted Shares that Exchangeco is unable to
redeem. In any such event, Exchangeco hereby agrees with the Trustee and in
favour of the Beneficiary promptly to forward or cause to be forwarded to the
Trustee all relevant materials delivered by the Beneficiary to Exchangeco or to
the transfer agent of the Exchangeable Shares (including a copy of the
retraction request delivered pursuant to Section 6.1 of the Exchangeable Share
Provisions) in connection with such proposed redemption of the Retracted Shares
and the Trustee will thereupon exercise the Exchange Right with respect to the
Retracted Shares that Exchangeco is not permitted to redeem and will require
Duke Energy to purchase such shares in accordance with the provisions of this
Article 5.

      5.8   Stamp or Other Transfer Taxes

      Upon any sale of Exchangeable Shares to Duke Energy pursuant to the
Exchange Right or the Automatic Exchange Rights, the share certificate or
certificates representing Duke Energy Common Shares to be delivered in
connection with the payment of the purchase price therefor shall be issued in
the name of the Beneficiary in respect of the Exchangeable Shares so sold or in
such names as such Beneficiary may otherwise direct in writing without charge to
the holder of the Exchangeable Shares so sold; provided, however, that such
Beneficiary (a) shall pay (and none of Duke Energy, Exchangeco or the Trustee
shall be required to pay) any documentary, stamp, transfer or other taxes that
may be payable in respect of any transfer involved in the issuance or delivery
of such shares to a person other than such Beneficiary or (b) shall have
evidenced to the satisfaction of the Trustee, Duke Energy and Exchangeco that
such taxes, if any, have been paid.

      5.9   Notice of Insolvency Event

      As soon as practicable following the occurrence of an Insolvency Event or
any event that with the giving of notice or the passage of time or both would be
an Insolvency Event, Exchangeco and Duke Energy shall give written notice
thereof to the Trustee. As soon as practicable following the receipt of notice
from Exchangeco and Duke Energy of the occurrence

                                      -15-
                      VOTING AND EXCHANGE TRUST AGREEMENT
<PAGE>

of an Insolvency Event, or upon the Trustee becoming aware of an Insolvency
Event, the Trustee will mail to each Beneficiary, at the expense of Duke Energy
(such funds to be received in advance), a notice of such Insolvency Event in the
form provided by Duke Energy, which notice shall contain a brief statement of
the rights of the Beneficiaries with respect to the Exchange Right.

      5.10  Qualification of Duke Energy Common Shares

      Duke Energy covenants that if any Duke Energy Common Shares to be issued
and delivered pursuant to the Exchange Right or the Automatic Exchange Rights
require registration or qualification with or approval of or the filing of any
document, including any prospectus or similar document, or the taking of any
proceeding with or the obtaining of any order, ruling or consent from any
governmental or regulatory authority under any Canadian or United States
federal, provincial, territorial or state law or regulation or pursuant to the
rules and regulations of any regulatory authority or the fulfillment of any
other Canadian or United States federal, provincial, territorial or state legal
requirement before such shares may be issued and delivered by Duke Energy to the
initial holder thereof or in order that such shares may be freely traded
thereafter (other than any restrictions of general application on transfer by
reason of a holder being a "control person" of Duke Energy for purposes of
Canadian provincial securities law or an "affiliate" of Duke Energy for purposes
of United States federal or state securities law), Duke Energy will in good
faith take all such actions and do all such things as are necessary or desirable
to cause such Duke Energy Common Shares to be and remain duly registered,
qualified or approved under United States and/or Canadian law, as the case may
be, to the extent expressly provided in the Combination Agreement. Duke Energy
will use its reasonable best efforts and in good faith expeditiously take all
such actions and do all such things as are reasonably necessary or desirable to
cause all Duke Energy Common Shares to be delivered pursuant to the Exchange
Right or the Automatic Exchange Rights to be listed, quoted or posted for
trading on all stock exchanges and quotation systems on which outstanding Duke
Energy Common Shares are listed, quoted or posted for trading at such time.

      5.11  Duke Energy Common Shares

      Duke Energy hereby represents, warrants and covenants that the Duke Energy
Common Shares issuable to Beneficiaries as described herein will be duly
authorized and validly issued, fully paid and non-assessable and shall be free
and clear of any lien, claim or encumbrance.

      5.12  Automatic Exchange on Liquidation of Duke Energy

      (a)   Duke Energy will give the Trustee written notice of each of the
            following events at the time set forth below:

            (i)   in the event of any determination by the Board of Directors of
                  Duke Energy to institute voluntary liquidation, dissolution or
                  winding-up proceedings with respect to Duke Energy or to
                  effect any other distribution of assets of Duke Energy among
                  its shareholders for the purpose of winding up its affairs, at
                  least 60 days prior to the proposed effective date of such
                  liquidation, dissolution, winding-up or other distribution;
                  and

                                      -16-
                      VOTING AND EXCHANGE TRUST AGREEMENT
<PAGE>

            (ii)  promptly following the earlier of (A) receipt by Duke Energy
                  of notice of, and (B) Duke Energy otherwise becoming aware of,
                  any threatened or instituted claim, suit, petition or other
                  proceedings with respect to the involuntary liquidation,
                  dissolution or winding-up of Duke Energy or to effect any
                  other distribution of assets of Duke Energy among its
                  shareholders for the purpose of winding up its affairs, in
                  each case where Duke Energy has failed to contest in good
                  faith any such proceeding commenced in respect of Duke Energy
                  within 30 days of becoming aware thereof.

      (b)   Promptly following receipt by the Trustee from Duke Energy of notice
            of any event (a "Liquidation Event") contemplated by Section 5.12(a)
            above, the Trustee will give notice or cause such notice to be given
            thereof to the Beneficiaries. Such notice shall be provided to the
            Trustee by Duke Energy and shall include a brief description of
            rights of the Beneficiaries with respect to the Automatic Exchange
            Rights provided for in Section 5.12(c).

      (c)   In order that the Beneficiaries will be able to participate on a pro
            rata basis with the holders of Duke Energy Common Shares in the
            distribution of assets of Duke Energy in connection with a
            Liquidation Event, immediately prior to the effective time (the
            "Liquidation Event Effective Time") of a Liquidation Event all of
            the then outstanding Exchangeable Shares shall be automatically
            exchanged for Duke Energy Common Shares. To effect such automatic
            exchange, Duke Energy shall purchase each Exchangeable Share
            outstanding immediately prior to the Liquidation Event Effective
            Time and held by Beneficiaries, and each Beneficiary shall sell the
            Exchangeable Shares held by such Beneficiary at such time, for a
            purchase price per share equal to the Exchangeable Share Price
            applicable at that time. Duke Energy shall provide the Trustee with
            an Officer's Certificate in connection with any automatic exchange
            setting forth the calculation of the Exchangeable Share Price for
            each Exchangeable Share.

      (d)   The closing of the transaction of purchase and sale contemplated by
            the automatic exchange of Exchangeable Shares for Duke Energy Common
            Shares shall be deemed to have occurred immediately prior to the
            Liquidation Event Effective Time, and each Beneficiary shall be
            deemed to have transferred to Duke Energy all of the Beneficiary's
            right, title and interest in and to such Beneficiary's Exchangeable
            Shares and the related interest in the Trust Estate. Any right of
            each such Beneficiary to receive declared and unpaid dividends from
            Exchangeco shall be deemed to be satisfied and discharged and each
            such Beneficiary shall cease to be a holder of such Exchangeable
            Shares and Duke Energy shall deliver to the Beneficiary the
            Exchangeable Share Consideration deliverable upon the automatic
            exchange of Exchangeable Shares. Concurrently with such Beneficiary
            ceasing to be a holder of Exchangeable Shares, the Beneficiary shall
            be considered and deemed for all purposes to be the holder of the
            Duke Energy Common Shares issued pursuant to the automatic exchange
            of Exchangeable Shares for Duke Energy Common Shares and the
            certificates held by the Beneficiary previously representing the
            Exchangeable Shares exchanged by the Beneficiary with Duke Energy
            pursuant to such automatic exchange shall thereafter be deemed to
            represent Duke Energy Common Shares

                                      -17-
                      VOTING AND EXCHANGE TRUST AGREEMENT
<PAGE>

            issued to the Beneficiary by Duke Energy pursuant to such automatic
            exchange. Upon the request of a Beneficiary and the surrender by the
            Beneficiary of Exchangeable Share certificates deemed to represent
            Duke Energy Common Shares, duly endorsed in blank and accompanied by
            such instruments of transfer as Duke Energy may reasonably require,
            Duke Energy shall deliver or cause to be delivered to the
            Beneficiary certificates representing Duke Energy Common Shares of
            which the Beneficiary is the holder.

      5.13  Withholding Rights

      Duke Energy, Exchangeco and the Trustee shall be entitled to deduct and
withhold from any consideration otherwise payable under this Agreement to any
holder of Exchangeable Shares or Duke Energy Common Shares such amounts as Duke
Energy, Exchangeco or the Trustee is required to deduct and withhold with
respect to such payment under the Income Tax Act (Canada), the United States
Internal Revenue Code of 1986 or any provision of federal, provincial, state,
local or foreign tax law, in each case as amended or succeeded. The Trustee may
act on the advice of counsel with respect to such matters. To the extent that
amounts are so withheld, such withheld amounts shall be treated for all purposes
as having been paid to the holder of the shares in respect of which such
deduction and withholding was made, provided that such withheld amounts are
actually remitted to the appropriate taxing authority. To the extent that the
amount so required to be deducted or withheld from any payment to a holder
exceeds the cash portion of the consideration otherwise payable to the holder,
Duke Energy, Exchangeco and the Trustee are hereby authorized to sell or
otherwise dispose of such portion of the consideration as is necessary to
provide sufficient funds to Duke Energy, Exchangeco or the Trustee, as the case
may be, to enable it to comply with such deduction or withholding requirement
and Duke Energy, Exchangeco or the Trustee shall notify the holder thereof and
remit to such holder any unapplied balance of the net proceeds of such sale.
Duke Energy represents and warrants that, based upon facts currently known to
it, it has no current intention, as at the date of this Agreement, to deduct or
withhold from any consideration paid to holders of Exchangeable Shares any
amounts under the United States Internal Revenue Code of 1986.

            Rights from Duke Energy as trustee for and on behalf of the
            Beneficiaries in accordance with the provisions of this Agreement;

      (e)   exercising the Exchange Right and enforcing the benefit of the
            Automatic Exchange Rights, in each case in accordance with the
            provisions of this Agreement, and in connection therewith receiving
            from Beneficiaries Exchangeable Shares and other requisite documents
            and distributing to such Beneficiaries Duke Energy Common Shares and
            cheques, if any, to which such Beneficiaries are entitled upon the
            exercise of the Exchange Right or pursuant to the Automatic Exchange
            Rights, as the case may be;

      (f)   holding title to the Trust Estate;

      (g)   investing any moneys forming, from time to time, a part of the Trust
            Estate as provided in this Agreement;

      (h)   taking action on its own initiative or at the direction of a
            Beneficiary or Beneficiaries to enforce the obligations of Duke
            Energy and Exchangeco under this Agreement; and

      (i)   taking such other actions and doing such other things as are
            specifically provided in this Agreement.

      In the exercise of such rights, powers, duties and authorities, the
Trustee shall have (and is granted) such incidental and additional rights,
powers, duties and authority not in conflict with any of the provisions of this
Agreement as the Trustee, acting in good faith and in the reasonable exercise of
its discretion, may deem necessary, appropriate or desirable to effect the
purpose of the Trust. Any exercise of such discretionary rights, powers, duties
and authorities by the Trustee shall be final, conclusive and binding upon all
persons.

      The Trustee in exercising its rights, powers, duties and authorities
hereunder shall act honestly and in good faith and with a view to the best
interests of the Beneficiaries and shall exercise the care, diligence and skill
that a reasonably prudent trustee would exercise in comparable circumstances.

action or proceeding by virtue of the powers conferred on it hereby unless and
until it shall be specifically required to do so under the terms hereof, nor
shall the Trustee be required to take any notice of, or to do, or to take any
act, action or proceeding as a result of any default or breach of any provision
hereunder, unless and until notified in writing of such default or breach, which
notices shall distinctly specify the default or breach desired to be brought to
the attention of the Trustee, and in the absence of such notice the Trustee may
for all purposes of this Agreement conclusively assume that no default or breach
has been made in the observance or performance of any of the representations,
warranties, covenants, agreements or conditions contained herein.

      The Trustee represents to Duke Energy and Exchangeco that at the date of
execution and delivery of this Agreement there exists no material conflict of
interest in the role of the Trustee as a fiduciary hereunder and the role of the
Trustee in any other capacity. The Trustee shall, within 90 days after it
becomes aware that such material conflict of interest exists, either eliminate
such material conflict of interest or resign in the manner and with the effect
specified in Article 10. If, notwithstanding the foregoing provisions of this
Section 6.2, the Trustee has such a material conflict of interest, the validity
and enforceability of this Agreement shall not be affected in any manner
whatsoever by reason only of the existence of such material conflict of
interest. If the Trustee contravenes the foregoing provisions of this Section
6.2, any interested party may apply to the Court for an order that the Trustee
be replaced as trustee hereunder.

            Energy Common Shares; and

      (b)   requisition, from time to time, (i) from any such registrar or
            transfer agent any information readily available from the records
            maintained by it which the Trustee may reasonably require for the
            discharge of its duties and responsibilities under this Agreement
            and (ii) from the transfer agent of Duke Energy Common Shares, and
            any subsequent transfer agent of such shares, the share certificates
            issuable upon the exercise from time to time of the Exchange Right
            and pursuant to the Automatic Exchange Rights.

      Duke Energy and Exchangeco irrevocably authorize their respective
registrars and transfer agents to comply with all such requests. Duke Energy

certificates for the purpose of completing the exercise from time to time of the
Exchange Right and the Automatic Exchange Rights.

      (b)   the number of exercises of the Exchange Right, if any, and the
            aggregate number of Exchangeable Shares received by the Trustee on
            behalf of Beneficiaries in consideration of the issuance by Duke
            Energy of Duke Energy Common Shares in connection with the Exchange
            Right, during the calendar year ended on such December 31; and

      (c)   any action taken by the Trustee in the performance of its duties
            under this Agreement which it had not previously reported and which,
            in the Trustee's opinion, materially affects the Trust Estate.

      6.5   Income Tax Returns and Reports

      The Trustee shall, to the extent necessary, prepare and file on behalf of
the Trust appropriate United States and Canadian income tax returns and any
other returns or reports as may be required by applicable law or pursuant to the
rules and regulations of any securities exchange or other trading system through
which the Exchangeable Shares are traded. In connection therewith, the Trustee
may obtain the advice and assistance of such experts or advisors as the Trustee
reasonably considers necessary or advisable (who may be experts or advisors to
Duke Energy or Exchangeco). If requested by the Trustee, Duke Energy or
Exchangeco shall retain qualified experts or advisors for the purpose of
providing such tax advice or assistance.

      6.6   Indemnification Prior to Certain Actions by Trustee

      The Trustee shall exercise any or all of the rights, duties, powers or
authorities vested in it by this Agreement at the request, order or direction of
any Beneficiary upon such Beneficiary furnishing to the Trustee reasonable
funding, security or indemnity against the costs, expenses and liabilities which
may be incurred by the Trustee therein or thereby, provided that no Beneficiary
shall be obligated to furnish to the Trustee any such security or indemnity in
connection with the exercise by the Trustee of any of its rights, duties, powers
and authorities with respect to the Duke Energy Common Shares held by the
Trustee pursuant to Article 4, subject to Section 6.15, with respect to the
Exchange Right pursuant to Article 5, subject to Section 6.15, and with respect
to the Automatic Exchange Rights pursuant to Article 5, subject to Section 6.15.

      None of the provisions contained in this Agreement shall require the
Trustee to expend or risk its own funds or otherwise incur financial liability
in the exercise of any of its rights, powers, duties, or authorities unless
funded, given security or indemnified as aforesaid.

      6.7   Action of Beneficiaries

      No Beneficiary shall have the right to institute any action, suit or
proceeding or to exercise any other remedy authorized by this Agreement for the
purpose of enforcing any of its rights or for the execution of any trust or
power hereunder unless the Beneficiary has requested the Trustee to take or
institute such action, suit or proceeding and furnished the Trustee with the
funding, security or indemnity referred to in Section 6.6 and the Trustee shall
have failed to act within a reasonable time thereafter. In such case, but not
otherwise, the Beneficiary shall be entitled to take proceedings in any court of
competent jurisdiction such as the Trustee might have

the Voting Rights, the Exchange Rights or the Automatic Exchange Rights except
subject to the conditions and in the manner herein provided, and that all powers

                                   ARTICLE 8
                 INDEMNIFICATION AND LIMITATION OF LIABILITY

      8.1   Indemnification of the Trustee

      Duke Energy and Exchangeco jointly and severally agree to indemnify and
hold harmless the Trustee and each of its directors, officers, employees and
agents appointed and acting in accordance with this Agreement (collectively, the
"Indemnified Parties") against all claims, losses, damages, reasonable costs,
penalties, fines and reasonable expenses (including reasonable expenses of the
Trustee's legal counsel) which, without fraud, gross negligence, recklessness,
willful misconduct or bad faith on the part of such Indemnified Party, may be
paid, incurred or suffered by the Indemnified Party by reason or as a result of
the Trustee's acceptance or administration of the Trust, its compliance with its
duties set forth in this Agreement, or any written or oral instruction delivered
to the Trustee by Duke Energy or Exchangeco pursuant hereto.

      In no case shall Duke Energy or Exchangeco be liable under this indemnity
for any claim against any of the Indemnified Parties unless Duke Energy and
Exchangeco shall be notified by the Trustee of the written assertion of a claim
or of any action commenced against the Indemnified Parties, promptly after any
of the Indemnified Parties shall have received any such written assertion of a
claim or shall have been served with a summons or other first legal process
giving information as to the nature and basis of the claim. Subject to (ii)
below, Duke Energy and Exchangeco shall be entitled to participate at their own
expense in the defense and, if Duke Energy and Exchangeco so elect at any time
after receipt of such notice, either of them may assume the defense of any suit
brought to enforce any such claim. The Trustee shall have the right to employ
separate counsel in any such suit and participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of the Trustee
unless: (i) the employment of such counsel has been authorized by Duke Energy or
Exchangeco; or (ii) the named parties to any such suit include both the Trustee
and Duke Energy or Exchangeco and the Trustee shall have been advised by counsel
acceptable to Duke Energy or Exchangeco that there may be one or more legal
defenses available to the Trustee that are different from or in addition to
those available to Duke Energy or Exchangeco and that, in the judgment of such
counsel, would present a conflict of interest were a joint representation to be
undertaken (in which case Duke Energy and Exchangeco shall not have the right to
assume the defense of such suit on behalf of the Trustee but shall be liable to
pay the reasonable fees and expenses of counsel for the Trustee). This indemnity
shall survive the termination of this Agreement and the resignation or removal
of the Trustee.

      8.2   Limitation of Liability

      The Trustee shall not be held liable for any loss which may occur by
reason of depreciation of the value of any part of the Trust Estate or any loss
incurred on any investment of funds pursuant to this Agreement, except to the
extent that such loss is attributable to the fraud, gross negligence,
recklessness, willful misconduct or bad faith on the part of the Trustee.

      9.1   Resignation

      The Trustee, or any trustee hereafter appointed, may at any time resign by
giving written notice of such resignation to Duke Energy and Exchangeco
specifying the date on which it desires to resign, provided that such notice
shall not be given less than thirty (30) days before such desired resignation
date unless Duke Energy and Exchangeco otherwise agree and provided further that
such resignation shall not take effect until the date of the appointment of a
successor trustee and the acceptance of such appointment by the successor
trustee. Upon receiving such notice of resignation, Duke Energy and Exchangeco
shall promptly appoint a successor trustee, which shall be a corporation
organized and existing under the laws of the State of New York or the State of
Delaware, by written instrument in duplicate, one copy of which shall be
delivered to the resigning trustee and one copy to the successor trustee.
Failing the appointment and acceptance of a successor trustee, a successor
trustee may be appointed by order of a court of competent jurisdiction upon
application of one or more of the parties to this Agreement. If the retiring
trustee is the party initiating an application for the appointment of a
successor trustee by order of a court of competent jurisdiction, Duke Energy and
Exchangeco shall be jointly and severally liable to reimburse the retiring
trustee for its legal costs and expenses in connection with same.

      9.2   Removal

      The Trustee, or any trustee hereafter appointed, may (provided a successor
trustee is appointed) be removed at any time on not less than 30 days' prior
notice by written instrument executed by Duke Energy and Exchangeco, in
duplicate, one copy of which shall be delivered to the trustee so removed and
one copy to the successor trustee.

      9.3   Successor Trustee

      Any successor trustee appointed as provided under this Agreement shall
execute, acknowledge and deliver to Duke Energy and Exchangeco and to its
predecessor trustee an instrument accepting such appointment. Thereupon the
resignation or removal of the predecessor trustee shall become effective and
such successor trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, duties and obligations of its
predecessor under this Agreement, with the like effect as if originally named as
trustee in this Agreement. However, on the written request of Duke Energy and
Exchangeco or of the successor trustee, the trustee ceasing to act shall, upon
payment of any amounts then due it pursuant to the provisions of this Agreement,
execute and deliver an instrument transferring to such successor trustee all the
rights and powers of the trustee so ceasing to act. Upon the request of any such
successor trustee, Duke Energy, Exchangeco and such predecessor trustee shall
execute any and all instruments in writing for more fully and certainly vesting
in and confirming to such successor trustee all such rights and powers.

            of such transaction, a trust agreement supplemental hereto and such
            other instruments (if any) as are satisfactory to the Trustee,
            acting reasonably, and in the opinion of legal counsel to the

            payable and property deliverable hereunder and the covenant of such
            Duke Energy Successor to pay and deliver or cause to be delivered
