               controls and procedures were adequate and designed to ensure that

               in our internal control over financial reporting that occurred
               during our last fiscal quarter that has materially affected, or
               is reasonably likely to materially affect, our internal control
               over financial reporting.

                       NOVA Chemicals: Results Strengthen

    PITTSBURGH--(BUSINESS WIRE)--Oct. 20, 2004--NOVA Chemicals
Corporation (NYSE:NCX) (TSX:NCX)

    NOVA Chemicals will host a conference call today, Wednesday, Oct.
20, 2004, for investors and analysts at 1 p.m. EDT (11 a.m. MDT; 10
a.m. PDT). Media are welcome to join this call in a "listen only"
mode. The dial in number for this call is (416) 405-9328. The replay
number is (416) 695-5800 (Reservation No. 3099681). The live call is
also available on the Internet at www.vcall.com.

    All financial information is in U.S. dollars unless otherwise
indicated.

    NOVA Chemicals Corporation (NOVA Chemicals) reported net income to
common shareholders of $56 million ($0.60 per share diluted) for the
third quarter of 2004. This compares to net income to common
shareholders of $27 million ($0.30 per share diluted) in the second
quarter of 2004.
    In the third quarter of 2003, NOVA Chemicals reported a net loss
to common shareholders of $65 million ($0.75 per share diluted). Net
income to common shareholders in the third quarter of 2004 rose $121
million compared to the third quarter of 2003.
    "Net income from our Olefins/Polyolefins and Styrenics businesses
was up sharply from $36 million in the second quarter to $68 million
in the third quarter, despite higher feedstock costs. We experienced
stronger demand in all of our markets and hit an all-time quarter
high for polyethylene volume in a period that is normally limited by
summer slowdowns," said Jeff Lipton, NOVA Chemicals' President and
Chief Executive Officer.
    "We closed the quarter with a strong cash position, even with
increases in working capital and the repurchase of 2.2 million shares
for $72 million. As we enter the fourth quarter, volume remains
strong, additional price increases are being implemented and our share
repurchase program remains on track."
    The Olefins/Polyolefins business reported net income of $78
million in the third quarter, $19 million higher than the second
quarter. Polyethylene sales volumes were up, prices increased and
contributions from co-products remained strong.
    The Styrenics business reported a net loss of $10 million in the
third quarter, versus a second quarter net loss of $23 million. Both
North American and European polymer results improved as prices
outpaced rising feedstock costs. Styrene monomer margins held steady
on slightly higher volumes despite the flow-through of much higher
benzene costs.
    Corporate items reduced net income by $11 million in the third
quarter of 2004. This included a $21 million (after-tax)
mark-to-market charge resulting from the impact of NOVA Chemicals'
stock price appreciation on cash settled stock-based compensation
plans. This charge was somewhat offset by a $10 million after-tax gain
related to an income tax settlement.

(1) In the third quarter of 2004, NOVA Chemicals began classifying
    mark-to-market amounts related to stock based compensation
    liabilities in the corporate accounts to more clearly present our

million in the third quarter of 2004, compared to net income of $59
million in the second quarter of 2004. Strong polymer demand enabled
price increases and margin expansion. Continued strong co-product
contributions, primarily from our Corunna, Ontario flexi-cracker,
largely offset rising feedstock costs.

    Feedstocks and Ethylene

    Average NYMEX natural gas prices were down 2% from the second
quarter and average WTI crude oil prices were up 15%.
    Our Joffre, Alberta ethane-based crackers' cash-cost advantage
averaged approximately 10 cents per pound for the quarter over typical
ethane-based U.S. Gulf Coast (USGC) ethylene plants. The increase in
the Alberta Advantage from 5 cents per pound in the second quarter was
driven by higher ethane prices on the U.S. Gulf Coast and declining
natural gas prices in Alberta.
    Third party ethylene sales volumes were down versus the second
quarter, as Alberta-based customers modified order patterns.

    Polyethylene

    Third quarter weighted-average benchmark polyethylene prices were
up about 3 cents per pound from the second quarter of 2004. A 4 cents
per pound polyethylene price increase in North America announced July
1, was fully implemented by the end of the third quarter. Additional
price increases of 5 cents per pound were announced for Sept. 1 and 6
cents per pound for Oct. 1, 2004.
    Total polyethylene sales volumes for the third quarter were up 2%
from the second quarter, and up 15% from the third quarter of 2003,
setting a new record. North American volumes were up 3% from the
second quarter, and international volumes were flat. International
sales represented 15% of NOVA Chemicals' total polyethylene sales
volume this quarter.

    Advanced SCLAIRTECH(TM) Polyethylene

    The Advanced SCLAIRTECH polyethylene plant, at Joffre, Alberta,
sold 198 million pounds of Advanced SCLAIRTECH polyethylene in the
third quarter of 2004 and sales of higher-margin performance grades,
including new rotational molding and thin wall injection molding
products, represented approximately 35% of plant capacity.

    Third Quarter 2004 versus Third Quarter 2003

    Net income of $78 million in the third quarter of 2004 was up from
a net loss of $8 million in the third quarter of 2003, primarily due
to strong industry operating rates driving up polyethylene margins, as
well as stronger co-product contributions. As reported by The American
Plastics Council (APC), industry operating rates for polyethylene in
North America improved from 83% in the third quarter of 2003 to 97% in
the third quarter of 2004. Effective industry operating rates for
ethylene in the United States, as reported by Chemical Market
Associates, Inc. (CMAI), for the third quarter of 2004 were 95%, up
from 88% in the third quarter of 2003.

    First Nine Months of 2004 versus First Nine Months of 2003

    Net income of $172 million in the first nine months of 2004 was up
from a net loss of $9 million in the first nine months of 2003. EBITDA
was also $268 million higher during the same period, due to strong
industry operating rates driving improvement in polyethylene margins,
as well as stronger co-product contributions. During the first nine
months of 2004, APC reported that North American industry operating
rates for polyethylene improved to 93%, up from 84% for the same
period in 2003. CMAI reported effective industry operating rates for
ethylene in the United States for the first nine months of 2004 of 95%
versus 87% for the same period in 2003.
    Our ability to implement announced price increases depends on many
factors that may be beyond our control, including market conditions,
the supply/demand balance for each particular product and feedstock
costs. Successful price increases, when realized, are typically phased
in over several months, vary by product or market, and can be reduced
in magnitude during the anticipated implementation period. See

    Review of Operations

    Styrenics

    Third Quarter 2004

    The Styrenics business reported a net loss of $10 million in the
third quarter, compared to a net loss of $23 million in the second
quarter of 2004. Polymer margins improved in North America and Europe,
as price increases more than offset the flow-through of higher
feedstock costs. Average realized prices and margins increased across
all polymer businesses in North America and Europe.
    Third-party styrene monomer sales volume was up 6% from the second
quarter, driven by improving global demand. North American and
European polymer volumes were essentially flat over the second
quarter.

    Styrene Monomer

    The USGC third quarter average spot price for styrene was 57 cents
per pound, up from the second quarter average price of 41 cents per
pound. Average third quarter benchmark contract pricing was 66 cents
per pound, up from the second quarter price of 53 cents per pound.
    Feedstock costs continued to increase through the third quarter
and the benzene benchmark rose to an average of $3.62 per gallon, up
from the second quarter average of $2.41 per gallon. Benzene remains
extremely tight and prices continue to be very high as a percentage of
crude oil. The contract benzene price reached an all-time high of
$3.95 per gallon for September, and spot prices also reached new
all-time highs.
    NOVA Chemicals announced price increases for North American
styrene monomer of 7 cents per pound effective July 1, 2004; 15 cents
per pound effective Aug. 1, 2004; 5 cents per pound effective Sept. 1,
2004; and 2 cents per pound effective Oct. 1, 2004.
    In Europe, the third quarter average price for styrene monomer was
59 cents per pound, up from the second quarter price of 46 cents per
pound.

    Solid Polystyrene (SPS)

    The weighted-average North American SPS benchmark price increased
from the second quarter by 12 cents per pound. SPS margins expanded in
North America and Europe during the third quarter as prices rose
faster than feedstock flow-through costs.
    NOVA Chemicals announced a price increase for North American SPS
of 3 cents per pound effective July 1, 2004; 4 cents per pound
effective Aug. 1, 2004; 12 cents per pound effective Aug. 16, 2004;
and 8 cents per pound effective Sept. 15, 2004.
    NOVA Chemicals announced European SPS price increases of 6 cents
per pound effective July 1, 2004; 8 cents per pound effective Aug. 1,
2004; 8 cents per pound effective Sept. 1, 2004; and 5.5 cents per
pound effective Oct. 1, 2004.

    Expandable Polystyrene (EPS)

    EPS margins expanded during the third quarter in North America and
Europe as prices rose faster than feedstock flow-through costs.
    NOVA Chemicals announced North American EPS price increases of 3
cents per pound effective July 1, 2004; 4 cents per pound effective
Aug. 1, 2004; 10 cents per pound effective Aug. 16, 2004; 8 cents per
pound effective Sept. 1, 2004; and 5 cents per pound effective Nov. 1,
2004.
    NOVA Chemicals announced European EPS price increases of 5 cents
per pound effective July 1, 2004; 9 cents per pound effective Aug. 1,
2004; 8 cents per pound effective Sept. 1, 2004; 3 cents per pound
effective Oct. 1, 2004; and 2.5 cents per pound effective Nov. 1,
2004.

    Third Quarter 2004 versus Third Quarter 2003

    The Styrenics business had a net loss of $10 million in the third
quarter of 2004, compared to a net loss of $39 million in the third
quarter of 2003, primarily due to the expansion of margins in all of
our polymer businesses in North America and Europe as prices outpaced
rising feedstock costs.

    First Nine Months of 2004 versus First Nine Months of 2003

    The net loss of $53 million in the first nine months of 2004
improved from the net loss of $98 million in the first nine months of
2003, primarily due to the expansion of margins in all of our polymer
businesses in North America and Europe as prices outpaced rising
feedstock costs. Volume increased 14% over this period.
    Our ability to implement announced price increases depends on many
factors that may be beyond our control, including market conditions,
the supply/demand balance for each particular product and feedstock
costs. Successful price increases, when realized, are typically phased
in over several months, vary by product or market, and can be reduced
in magnitude during the anticipated implementation period. See

    NOVA Chemicals' net debt to total capitalization ratio was 45.2%
at Sept. 30, 2004. Cash on hand at the end of the third quarter was
$233 million, down from $257 million at the end of the second quarter
of 2004. During the third quarter, $72 million of cash was used to
repurchase 2.2 million common shares.
    NOVA Chemicals' funds from operations were $141 million for the
third quarter of 2004, up $15 million from the second quarter of 2004
due to improved earnings during the quarter.
    Operating working capital increased by $56 million in the third
quarter of 2004, related primarily to price increases and inventory
builds associated with a maintenance turnaround at our Corunna crude
unit. NOVA Chemicals assesses its working capital management
effectiveness through a Cash Flow Cycle Time (CFCT) measure. CFCT
measures working capital from operations in terms of the number of
days sales (calculated as working capital from operations divided by
average daily sales). This metric helps determine which portion of
changes in working capital result from factors other than price
movements. CFCT was 33 days as of Sept. 30, 2004, above our target
range of 25 to 30 days, and up from 29 days as of June 30, 2004, due
to higher inventories and as a result of the scheduled maintenance at
Corunna.
    During the third quarter, NOVA Chemicals received $19 million from
the sale of its 100% interest in an ethylene delivery system in
Alberta. The gain of $19 million was deferred and will be amortized
over the life of an operating lease of the system. Capital
expenditures were $57 million (after third-party project advances) in
the third quarter of 2004, compared to $36 million in the second
quarter of 2004 and $35 million in the third quarter of 2003.
    Selling, general and administrative expenses (SG&A) increased by
$21 million from the second quarter of 2004. SG&A was also up $32
million from the third quarter of 2003, and $60 million for the first
nine months of 2004 versus the first nine months of 2003. These
increases were primarily due to NOVA Chemicals' stock appreciation and
the $52 million pre-tax impact on the mark-to-market liability of our
stock-based compensation plans.
    Depreciation and amortization declined $9 million in the third
quarter of 2004 versus the second quarter due to our second Joffre
ethylene plant being fully depreciated. Despite this decline,
depreciation for the first nine months of 2004 was up slightly from
the first nine months of 2003 due to the appreciation of the Canadian
dollar and euro.

    Financing

    NOVA Chemicals has a $300 million revolving credit facility,
expiring April 1, 2007. NOVA Chemicals continues to comply with all
financial covenants under the facility. As of Oct. 19, 2004, NOVA
Chemicals has utilized $53 million of the revolving credit facility in
the form of operating letters of credit.
    During the third quarter of 2004, NOVA Chemicals increased the
capacity of its accounts receivable securitization program from $200
million to $250 million. As of Sept. 30, 2004, the amount of
receivables sold under this program was $226 million, compared to $200
million as of June 30, 2004.

    Normal Course Issuer Bid

    On July 21, 2004, NOVA Chemicals announced a share repurchase
program for up to approximately 7.5 million common shares. As of Oct.
19, 2004, 2.2 million common shares have been repurchased at an
average price of $43.29 Cdn.

    FIFO Impact

    NOVA Chemicals uses the first-in, first-out (FIFO) method of
valuing inventory. Most of NOVA Chemicals' competitors use the
last-in, first-out (LIFO) method. Because we use FIFO, a portion of
the second quarter feedstock purchases flowed through the income
statement in the third quarter. Benzene and crude oil prices continued
to increase through the third quarter and natural gas prices fell
slightly. Third quarter average NYMEX natural gas pricing was lower
than the second quarter average price by $0.13 per mmBTU and WTI crude
was higher by $5.56 per bbl. Benchmark benzene prices continued to
rise, starting the quarter at $2.60 per gallon and ending the quarter
at $3.95 per gallon. We estimate that net income would have been about
$42 million lower in the third quarter had NOVA Chemicals used the
LIFO method of accounting.

    Feedstock Derivative Positions

    NOVA Chemicals maintains a derivatives program to manage its
feedstock costs. The loss from natural gas and crude oil positions
realized in the third quarter of 2004 was $3 million after-tax ($2
million gain after-tax in the first half of the year).
    In addition, NOVA Chemicals is required to record on its balance
sheet the market value of any outstanding feedstock positions that do
not qualify for hedge accounting treatment. The gain or loss resulting
from changes in the market value of positions is recorded through
earnings each period. NOVA Chemicals has recorded $11 million of
mark-to-market after-tax gains on outstanding feedstock derivative
positions since Jan. 1, 2004 (a $5 million gain in the first quarter,
a $1 million gain in the second quarter, and a $5 million gain in the
third quarter of 2004). This is in addition to the realized loss
reported above, bringing the total year-to-date gain to $10 million
after-tax.

    Supplemental Measures

    In addition to providing measures in accordance with Canadian
GAAP, NOVA Chemicals presents certain supplemental measures. These are
EBITDA (defined below), average capital employed (defined on page 2)
and after-tax return on capital employed (defined on page 2). It also
includes net debt to total capitalization (see page 8), with net debt
and total capitalization defined to be net of cash and cash
equivalents in accordance with the debt covenants for its $300 million
revolving credit facility. These measures do not have any standardized
meaning prescribed by GAAP and are therefore unlikely to be comparable
to similar measures presented by other companies.

    EBITDA

    This measure is provided to assist investors in determining the
ability of NOVA Chemicals to generate cash from operations. EBITDA can
be determined from the Consolidated Statement of Income by adding back
income taxes, interest expense, other gains and losses, earnings from
equity investment in affiliates and depreciation and amortization.
Segment EBITDA is determined as segment operating income or loss
before depreciation and amortization.

                      Forward-Looking Information

The information in this news release contains forward-looking
statements with respect to NOVA Chemicals, its subsidiaries and
affiliated companies. By their nature, these forward-looking
statements involve risks and uncertainties that could cause actual
results to differ materially from those contemplated by the
forward-looking statements. These risks and uncertainties include:
commodity chemicals price levels (which depend, among other things, on
supply and demand for these products, capacity utilization and
substitution rates between these products and competing products);
feedstock availability and prices; operating costs; terms and
availability of financing; technology developments; currency exchange
rate fluctuations; starting up and operating facilities using new
technology; realizing synergy and cost savings targets; meeting time
and budget targets for significant capital investments; avoiding
unplanned facility shutdowns; safety, health and environmental risks
associated with the operation of chemical plants and marketing of
chemical products, including transportation of these products; public
perception of chemicals and chemical end-use products; the impact of
competition; changes in customer demand; changes in, or the
introduction of new laws and regulations relating to NOVA Chemicals'
business, including environmental, competition and employment laws;
loss of the services of any of NOVA Chemicals' executive officers;
uncertainties associated with the North American, European and Asian
economies; and other risks detailed from time to time in the publicly
filed disclosure documents and securities commissions reports of NOVA
Chemicals and its subsidiaries or affiliated companies.

Implementation of announced price increases depends on many factors,
including market conditions, the supply/demand balance for each
particular product and feedstock costs. Price increases have varying
degrees of success. They are typically phased in and can differ by
product or market. There can be no assurances that any announced price
increases will be successful or will be realized within the
anticipated time frame. In addition, benchmark price indices sometimes
lag price increase announcements due to the timing of publication.

    Notes to Consolidated Financial Statements

    (unaudited; millions of U.S. dollars unless otherwise noted)

    These interim consolidated financial statements do not include all
of the disclosures included in NOVA Chemicals' annual Consolidated
Financial Statements. Accordingly, these interim consolidated
financial statements should be read in conjunction with the
Consolidated Financial Statements for the year ended Dec. 31, 2003.
Certain comparative amounts have been reclassified to conform with the
current period's presentation.

    1. Significant Accounting Policies

    These interim Consolidated Financial Statements have been prepared
in accordance with Canadian GAAP, using the same accounting policies
as set out in Note 2 to the Consolidated Financial Statements for the
year ended Dec. 31, 2003, on pages 53 to 57 of the 2003 Annual Report,
except as noted below.

    Changes in Accounting Policies Required by Canadian GAAP

    A. Stock Option Plan

    Effective Jan. 1, 2004, Canadian GAAP requires the fair value of
options to be expensed over their vesting period. Prior to Jan. 1,
2004, NOVA Chemicals followed the intrinsic-value approach, where the
granting and exercising of stock options are accounted for as equity
transactions and no amounts are expensed.
    NOVA Chemicals adopted the new accounting policy on a retroactive
basis with no restatement of prior periods. Accordingly, on Jan. 1,
2004, retained earnings was reduced and contributed surplus was
increased by $7 million to account for the stock option expense that
would have been charged to earnings (loss) in 2002 and 2003 with
respect to all stock options granted since Jan. 1, 2002. NOVA
Chemicals uses the Black-Scholes option valuation model to calculate
the fair value of stock options at the date of grant. In the first
nine months of 2004, compensationexpense related to stock options was
$3 million after-tax, which serve to increase contributed surplus.
    Effective Jan. 1, 2004, NOVA Chemicals also changed its accounting
policy with respect to stock options for U.S. GAAP reporting, to be
consistent with Canadian GAAP.
    Had NOVA Chemicals expensed the fair value of stock options in
prior periods, the following pro forma amounts would have resulted:

stock options granted since Jan. 1, 2002, based on the Black-Scholes
option valuation model are as follows:

    B. Valuing Derivatives

    Effective Jan. 1, 2004, NOVA Chemicals adopted a new Canadian
accounting policy that requires all derivative positions, except those
that qualify for hedge accounting treatment, to be marked-to-market at
each period end with any resulting gains or losses recorded in
earnings (loss).
    NOVA Chemicals adopted the new accounting policy on a prospective
basis. In accordance with the transitional provisions of the new
accounting policy, unrealized gains and losses that existed on Jan. 1,
2004 have been deferred on the consolidated balance sheet. These
amounts will be recognized in income over the remaining term to
maturity. In the first nine months of 2004, $11 million of unrealized
after-tax gains on derivatives have been recorded in earnings,
representing the increase in market value since Jan. 1, 2004.

(1) Income taxes on the Joffre, Alberta second ethylene plant were
    recoverable from customers until June 30, 2004 and were recorded
    on the flow-through rather than liability method. Subsequent to
    June 30, 2004, income taxes are being recorded on the liability
    method.
(2) In the first quarter of 2004, the Alberta Government substantively
    enacted a tax rate reduction, which reduced income tax accruals
    for future tax liabilities by $7 million. This one-time benefit
    has been recorded in the first quarter of 2004 through a reduction
    of income tax expense.

    No retractable preferred shares or stock options have been
excluded from the computation of diluted earnings per share for the
quarters ended Sept. 30 and June 30, 2004. A total of 17.6 million
common shares were excluded in the quarter ended Sept. 30, 2003, as
their impact would not have been dilutive.
    Options become dilutive when the market price is higher than the
strike price and NOVA Chemicals is profitable. The amount of dilution
will vary with the stock price. The retractable preferred shares are
only dilutive if our earnings per share is greater than the preferred
share dividend divided by the number of shares issued on conversion.
At today's common share price and LIBOR rate, these shares become
dilutive whenever earnings are greater than approximately $0.26 per
share per quarter.

(1) On Jan. 1, 2001, NOVA Chemicals adopted (for U.S. GAAP purposes)
    Statement of Financial Accounting Standards (SFAS) No. 133,
    "Accounting for Derivative Instruments and Hedging Activities," as
    amended. SFAS No. 133 requires the recognition of all derivatives
    on the balance sheet at fair value. Derivatives that do not
    qualify for preferential hedge accounting treatment must be
    adjusted to fair value through income. If the derivative does
    qualify, changes in the fair value of the derivative will either
    be offset against the change in fair value of the hedged item and
    reported in earnings, or recognized in other comprehensive income
    until the hedged item is recognized in earnings. On Jan. 1, 2004,
    NOVA Chemicals adopted a new Canadian GAAP guideline for recording
    the fair value of derivatives. This guideline harmonizes Canadian
    and U.S. GAAP, however, due to the differing implementation dates,
    timing differences continue to exist.
(2) U.S. GAAP requires an allocation of fixed production overhead to
    inventory. Canadian GAAP allows these costs to be expensed during
    the period.
(3) U.S. GAAP requires that all costs (except interest on constructed
    assets) associated with start-up activities be expensed as
    incurred rather than deferred, as under Canadian GAAP.
(4) Under U.S. GAAP distributions on the preferred securities are
    recorded as interest expense. The preferred securities were
    redeemed by NOVA Chemicals on Mar. 1, 2004.
(5) On Jan. 1, 2003, the company adopted SFAS No. 143 "Accounting for
    Asset Retirement Obligations." This standard and the CICA
    standard, also adopted on Jan. 1, 2003, are essentially the same.
    On Jan. 1, 2004, NOVA Chemicals adopted the CICA standard for
    expensing of stock options (as discussed in Note 1). This standard
    was also adopted for U.S. GAAP on that date. Under U.S. GAAP, the
    cumulative effect of adopting a new standard is reflected in net
    income in the period of adoption, whereas under Canadian GAAP it
    is reflected as a charge or credit to reinvested earnings.
(6) U.S. GAAP requires the presentation of a separate statement of
    comprehensive income (loss) and accumulated other comprehensive
    income. This statement is not required under Canadian GAAP.
    Comprehensive income (loss) includes certain changes in equity
    during the period that are not in net income.
(7) U.S. GAAP requires that an additional minimum pension liability be
    recorded through comprehensive income (loss) when the unfunded
    accumulated benefit obligation is greater than the accrued pension
    liability or if there is a prepaid pension asset.
(8) U.S. GAAP future income taxes are not adjusted for changes in tax
    rates until they are enacted, whereas Canadian GAAP requires
    adjustment when rate changes are substantively enacted.
(9) Gains (losses) resulting from translation of self-sustaining
    foreign operations are recorded in other comprehensive income
    until there is a realized reduction in the investment.

Dear Sirs/Mesdames:

Re:  NOVA Chemicals Corporation (the "Corporation")

We are the auditors of the Corporation and under date of February 12, 2004
we reported on the following consolidated financial statements of the
Corporation incorporated by reference in the amended and restated short form
shelf prospectus dated August 20, 2001 relating to the sale and issue of up to
US $500,000,000 of Debt Securities of the Corporation (the "Shelf Prospectus"):

     Consolidated balance sheets as at December 31, 2003, 2002, and 2001; and

     Consolidated statements of income (loss) and reinvested earnings and cash
     flows for each of the years in the three-year period ended December
     31, 2003.

The Shelf Prospectus also incorporates by reference the following unaudited
interim consolidated financial statements of the Corporation (the "Unaudited
Interim Financial Statements"):

     Consolidated balance sheet as at September 30, 2004;

     Consolidated statements of income (loss), reinvested earnings and cash
     flows for the three-month and nine-month periods ended September 30,
     2004 and 2003 and for the three-month period ended June 30, 2004.



                                      -2-

We have not audited any financial statements of the Corporation as at any
date or for any period subsequent to December 31, 2003. Although we have
performed an audit for the year ended December 31, 2003, the purpose and
therefore the scope of the audit was to enable us to express our opinion on the
consolidated financial statements as at December 31, 2003 and for the year then
ended, but not on the consolidated financial statements for any interim period
within that year. Therefore, we are unable to and do not express an opinion on
the above-mentioned Unaudited Interim Financial Statements, or on the financial
position, results of operations or cash flows as at any date or for any period
subsequent to December 31, 2003.

We have, however, performed a review of the Unaudited Interim Financial
Statements of the Corporation as at September 30, 2004 and for the three-month
and nine-month periods ended September 30, 2004 and 2003 and for the three-month
period ended June 30, 2004. We performed our review in accordance with Canadian
generally accepted standards for a review of interim financial statements by an
entity's auditor. Such an interim review consists principally of applying
analytical procedures to financial data, and making enquiries of, and having
discussions with, persons responsible for financial and accounting matters. An
interim review is substantially less in scope than an audit, whose objective is
the expression of an opinion regarding the financial statements. An interim
review does not provide assurance that we would become aware of any or all
significant matters that might be identified in an audit.

Based on our review, we are not aware of any material modification that
needs to be made for these Unaudited Interim Financial Statements to be in
accordance with Canadian generally accepted accounting principles.

This letter is provided solely for the purpose of assisting the securities
regulatory authorities to which it is addressed in discharging their
responsibilities and should not be used for any other purpose. Any use that a
third party makes of this letter, or any reliance or decisions made based on it,
are the responsibility of such third parties. We accept no responsibility for
loss or damages, if any, suffered by any third party as a result of decisions

Notes:

     (1)  Calculated in accordance with Canadian securities law disclosure
          requirements.

     (2)  Interest coverage on long-term debt is equal to net income (loss)
          before interest expense on long-term debt and income taxes, for the
          preceding 12 months, divided by annual interest requirements on
          long-term debt.

     (3)  Net tangible asset coverage on long-term debt is equal to total assets
          (excluding future tax assets) less liabilities (excluding long-term
          debt) divided by long-term debt.

     (4)  See attached for detailed calculation of the above coverage ratios.

For purposes of calculating these financial ratios, long-term debt includes
the long-term debt installments due within one year.

     establishing and maintaining disclosure controls and procedures (as defined
     in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and have:

          a)   designed such disclosure controls and procedures, or caused such
               disclosure controls and procedures to be designed under our
               supervision, to ensure that material information relating to the
               registrant, including its consolidated subsidiaries, is made
               known to us by others within those entities, particularly during
               the period in which this report is being prepared;

          b)   evaluated the effectiveness of the registrant's disclosure
               controls and procedures and presented in this report our
               conclusions about the effectiveness of the disclosure controls
               and procedures, as of the end of the period covered by this
               report based on such evaluation; and

          c)   disclosed in this report any change in the registrant's internal
               control over financial reporting that occurred during the period
               covered by the report that has materially affected, or is
               reasonably likely to materially affect, the registrant's internal
               control over financial reporting; and

5.   The registrant's other certifying officer and I have disclosed, based on
     our most recent evaluation of internal control over financial reporting, to
     the registrant's auditors and the audit committee of the registrant's board
     of directors (or persons performing the equivalent functions):

          a)   all significant deficiencies and material weaknesses in the
               design or operation of internal control over financial reporting
               which are reasonably likely to adversely affect the registrant's
               ability to record, process, summarize and report financial
               information; and

          b)   any fraud, whether or not material, that involves management or
               other employees who have a significant role in the registrant's
               internal control over financial reporting.
