                      NOVA Chemicals Q3 Results:
   Strong Demand, Tight Supply Driving Price and Margin Improvement

    PITTSBURGH--(BUSINESS WIRE)--Oct. 19, 2005--All financial
information is in U.S. dollars unless otherwise indicated.
    NOVA Chemicals Corporation (NOVA Chemicals)(NYSE:NCX)(TSX:NCX)
reported a net loss of $105 million ($1.28 per share loss diluted) for
the third quarter of 2005.
    Included in the third quarter 2005 loss is the estimated impact of
two unusual events totaling $95 million after-tax ($1.15 per share
loss diluted):

    --  Joffre ethane interruption ... $20 million

    --  Non-cash write-down primarily due to the European Styrenics
        joint venture ... $75 million

    This quarter's total net loss compares to a net loss of $25
million ($0.29 per share loss diluted) for the second quarter of 2005.
In the third quarter of 2004, NOVA Chemicals reported net income of
$56 million ($0.60 per share diluted).
    "The two hurricanes on the U.S. Gulf Coast created unprecedented
petrochemical and plastic resin production outages in a market that
was already strengthening due to low inventories and very healthy
demand," said Jeff Lipton, NOVA Chemicals' President and CEO. "NOVA
Chemicals continues to implement price increases that began early in
the third quarter; with margins now expanding despite higher feedstock
costs."

    Third Quarter Snapshot

    Olefins/Polyolefins:

    --  Net income of $39 million in Q3 2005 compares to $45 million
        in Q2 2005.

    --  Polyethylene sales volume was 2% lower than Q2 2005 due to the
        continued impact of planned and unplanned outages. The
        estimated loss of sales due to maintenance outages negatively
        impacted net income by $14 million.

    --  Polyethylene prices were up 5%.

    --  The sales volume loss due to the Alberta storm that
        interrupted ethane production is estimated to have negatively
        impacted net income by $20 million in Q3 2005, for a total
        impact of $24 million.

    Styrenics:

    --  Net loss of $59 million in Q3 2005 versus a net loss of $76
        million in Q2 2005.

    --  North American styrenic polymer prices declined 3% and sales
        volumes fell 6% primarily on weaker EPS demand.

    --  European styrenic polymer prices declined 3%, while sales
        volumes increased 11%

    --  Hurricanes Katrina and Rita forced the shutdown of 83% of
        North American styrene monomer capacity, resulting in the loss
        of more than 600 million pounds of production. Our Bayport, TX
        styrene site avoided significant damage.

    --  The NOVA Innovene JV in Europe commenced operations on October
        1 and took rapid steps to reduce fixed costs.

    Corporate:

    --  Debt repayment of $81 million; cash position at quarter-end of
        $97 million.

    --  Preferred shareholders agreed to a removal of the conversion
        feature of their shares, reducing potential share dilution by
        5.8 million shares. A share buy-back program for up to 7.2
        million shares was also announced.

    --  A non-cash write-down of $75 million was taken primarily due
        to the NOVA Innovene decision to cease EPS production at
        Berre, France and permanently shutdown the EPS plant at
        Carrington, UK.

(1) On Jan. 1, 2005, NOVA Chemicals adopted new Canadian accounting
    standards, which require the preferred shares of our subsidiary,
    NOVA Chemicals Inc., to be classified as debt. Accordingly, any
    dividends associated with these preferred shares are now
    classified as interest expense and allocated to our two
    businesses, Olefins/Polyolefins and Styrenics. All prior periods
    have been restated.
(2) See table on page 13 for a description of all corporate and other
    items.
(3) Weighted-average number of common shares outstanding during the
    period used to calculate the earnings (loss) per share. See page
    20, Note 5 for more information.
(4) For periods where there are losses, diluted shares are the same as
    basic shares because losses are not diluted.
(5) During Sept. 2005, the terms of the preferred shares of our
    subsidiary, NOVA Chemicals Inc., were amended to remove the
    feature allowing the holders, under certain circumstances, to
    convert the preferred shares to NOVA Chemicals' common shares.
    Accordingly, the preferred shares no longer impact diluted
    earnings per share.
(6) Net income before income taxes, other gains and losses, interest
    expense and depreciation and amortization. See Consolidated
    Statement of Net Income (Loss) and Reinvested Earnings on page 16
    and Supplemental Measures on page 12.
(7) Average capital employed equals cash expended on plant, property
    and equipment (less accumulated depreciation and amortization) and
    working capital, and excludes assets under construction and
    investments. Amounts are converted to U.S. dollars using
    quarter-end exchange rates. See Supplemental Measures on page 12.
(8) After-tax return (loss) on capital employed equals NOVA Chemicals'
    net income (loss) plus after-tax interest expense (annualized)
    divided by average capital employed. See Supplemental Measures on
    page 12.
(9) Return (loss) on average common equity equals annualized net
    income (loss) divided by average common equity.

    Review of Operations

    Olefins/Polyolefins

    The Olefins/Polyolefins business reported net income of $39
million in the third quarter of 2005 compared to net income of $45
million in the second quarter of 2005. Polyethylene sales volumes were
2% lower as a result of the ethane feedstock disruption at the Joffre
site and planned maintenance turnarounds. The Joffre site experienced
reduced ethane feed in July and August due to severe weather damage at
third-party ethane plants. Co-product sales volumes were down 13%
primarily due to the planned maintenance turnaround at the Corunna,
Ontario flexi-cracker.
    The negative impact to earnings of the planned turnarounds was
approximately $14 million in the third quarter of 2005 and is
projected to be $15-25 million in the fourth quarter, depending on
start-up timing. It is estimated that net income in the third quarter
of 2005 would have been $20 million greater had NOVA Chemicals not
experienced a loss of sales volume due to the June 21 Joffre ethane
feedstock reduction.
    In the third quarter of 2004, the Olefins/Polyolefins business
reported net income of $77 million. The year-over-year variance is
primarily attributed to planned and unplanned outages and co-product
sales volume reductions.
    Year-to-date, the Olefins/Polyolefins business reported net income
of $196 million compared to $167 million for the first nine months of
2004. The year-over-year variance is primarily due to product price
increases that out paced feedstock costs.

    Ethylene and Feedstocks

    For the third quarter, Chemical Markets Associates, Inc. (CMAI)
reported effective operating rates for ethylene in the U.S. of 94%
compared to 92% in the second quarter of 2005 and 95% in the third
quarter of 2004.
    CMAI benchmark USGC ethylene prices averaged 41 cents per pound in
the third quarter compared to 38 cents per pound in the second
quarter. CMAI reported USGC contract ethylene prices rose 0.5 cents
per pound in July, 3 cents per pound in Aug., and 5 cents per pound in
Sept., resulting in a net transaction contract price of 45.5 cents per
pound in Sept.
    The average price of West Texas Intermediate (WTI) crude oil was
up 19% to $63.19 per barrel in the third quarter and the average price
of NYMEX natural gas was up 21% to $8.25 per mmBTU. On Sept. 30, 2005
the closing market price for the NYMEX crude oil contract was $66.24
per barrel and the NYMEX natural gas contract was $13.92 per mmBTU.
    The basis differential between the Alberta AECO Daily Index and
Henry Hub Daily Cash natural gas prices averaged $1.90 per mmBTU for
the quarter, up from $1.02 per mmBTU in the second quarter of 2005. At
the end of the quarter, the basis differential was $2.65 per mmBTU.
The widening natural gas basis differential resulted in a calculated
average of 7 cents per pound Alberta Advantage in the third quarter.
NOVA Chemicals realized approximately 6 cents per pound of the Alberta
Advantage due to the negative effect of the ethane supply problems and
reduced production rates.

    Polyethylene

    NOVA Chemicals' total polyethylene sales volume for the third
quarter was 714 million pounds. Due to the continued impact of the
Joffre ethane outage and the planned maintenance turnarounds, NOVA
Chemicals' North American sales volume was flat compared to the second
quarter.
    International volumes declined 30% to 88 million pounds quarter
over quarter, representing 12% of NOVA Chemicals' total polyethylene
sales volume this quarter versus 17% in the previous quarter. In
Sept., when relative margins increased in the U.S., NOVA Chemicals
chose to significantly reduce International sales.
    NOVA Chemicals' polyethylene inventories were up from 18 days of
sales on June 30, 2005 to 21 days on Sept. 30, 2005 due to NOVA
Chemicals planned turnarounds. Over the same period, American Plastics
Council (APC) reported North American industry inventories were down
from 39 days of sales to 34 days of sales. APC also reported industry
operating rates for polyethylene in North America at an average of 93%
for July and Aug. but only 76% for Sept. due to the shut downs caused
by the hurricanes. As a result, APC reported third quarter 2005
industry operating rates for polyethylene in North America of 87%,
compared to 88% in the second quarter of 2005 and 97% in the third
quarter of 2004.
    Hurricanes Katrina and Rita forced the shutdown of several
Louisiana, Mississippi, and Texas Gulf Coast plants affecting 59% of
North American ethylene capacity and approximately 48% of North
American polyethylene capacity. To date, CMAI estimates the two
hurricanes' combined impact on industry production capacity resulted
in a reduction in ethylene production of approximately 3 billion
pounds and a reduction in polyethylene production of approximately 1.5
billion pounds.
    Third quarter weighted-average benchmark polyethylene prices were
up approximately 3 cents per pound from the second quarter of 2005.
NOVA Chemicals began to implement in North America a series of price
increases during the quarter. As of October 15, NOVA Chemicals had
announced price increases totaling 39 cents per pound:

 Nov. 1               +8 cpp
 Nov. 15              +7 cpp


    Performance Products

    NOVA Chemicals sold 153 million pounds of Advanced SCLAIRTECH
polyethylene in the third quarter, down from 183 million pounds in the
second quarter due to a planned maintenance outage. However, sales of
polyethylene Performance Products, including new SURPASS rotational
molding and thin-wall injection molding resins, increased to 127
million pounds or 60% of plant capacity in the third quarter, up from
105 million pounds or 50% of plant capacity in the second quarter.
Year-over-year, polyethylene Performance Products sales volume has
increased 76% from 186 million pounds to 328 million pounds. As a
result, year-over-year Standard Product sales volume decreased
approximately 50% from 387 million pounds to 198 million pounds.
    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
Forward-Looking Information on page 14.

    Review of Operations

    Styrenics

    The Styrenics business reported a net loss of $59 million in the
third quarter of 2005 compared to a net loss of $76 million in the
second quarter of 2005, largely due to more favorable feedstock costs.
Styrene monomer prices declined slightly. North American polymer
prices and volumes declined 3% and 6%, respectively. European polymer
prices declined 3% and volumes increased 11% compared to the second
quarter.
    In the third quarter of 2004, the Styrenics business reported a
net loss of $10 million. The year-over-year variance is attributed to
slightly lower margins and 11% lower volumes.
    Year-to-date, the Styrenics business reported a net loss of $156
million compared to $56 million for the first nine months of 2004. The
year-over-year variance is due to an 8% decline in third-party sales
volume, compounded by increasing feedstock and energy costs. Benzene
and ethylene prices have increased 14% and 25% respectively,
year-over-year.

    Styrene Monomer

    Quarter-over-quarter, styrene monomer margins were flat. In the
third quarter of 2005, average benchmark styrene monomer prices
declined by 1 cent per pound, compared to the second quarter of 2005.
    Benchmark benzene prices increased to $2.98 per gallon in July
from $2.30 per gallon in June before settling at $2.75 per gallon for
Aug. and Sept. The third quarter 2005 average price of benzene
decreased from $3.06 to $2.82 per gallon compared to the second
quarter, which is the equivalent of approximately 2 cents per pound of
styrene. Since peaking in the fourth quarter of 2004, benzene prices
are now at the lowest level relative to crude oil since the second
quarter of 2003.
    In the third quarter, third party styrene monomer sales volume was
down 3% compared to the second quarter. Production volume was reduced
due to planned turnarounds at Sarnia and Bayport. The Bayport plant
was also shutdown as a precaution on Sept. 21 in anticipation of
Hurricane Rita. The plant sustained minimal damage from the hurricane
and successfully re-started operations at reduced rates on Oct. 6.
Bayport is currently on allocation due to a force majeure declaration
issued because of hurricane-related feedstock constraints. We expect
the financial impact in the fourth quarter will be approximately $5
million. NOVA Chemicals estimates approximately 60 to 70 million
pounds of Bayport styrene monomer production was lost during the
outage.
    Hurricanes Katrina and Rita forced the shutdown of several styrene
monomer facilities located on the USGC and affected 83% of North
American capacity. CMAI estimates the styrene monomer production lost
due to the combined effects of the hurricanes was in excess of 600
million pounds.
    NOVA Chemicals announced two price increases for styrene monomer
during the quarter totaling 11 cents per pound:



  2005 Effective Date  Price Increase Announcements
  Sept. 1              +3 cpp
  Oct. 1               +8 cpp


    North American Solid Polystyrene (SPS)

    North American SPS sales volumes decreased 2%
quarter-over-quarter.

    North American benchmark SPS prices declined by approximately 3
cents per pound from the second quarter.
    NOVA Chemicals issued a force majeure for SPS in North America as
a result of the impact of Hurricane Rita.
    NOVA Chemicals began to implement a series of SPS price increases
during the quarter. As of Oct. 15, NOVA Chemicals had announced price
increases totaling 21 cents per pound:

    North American Expandable Polystyrene (EPS)

    North American EPS sales volumes fell 12% compared to second
quarter.

    North American benchmark EPS prices declined by 2 cents per pound
from the second quarter.
    NOVA Chemicals has announced the following North American price
increase:




  2005 Effective Date  Price Increase Announcement
  Nov. 1               +5 cpp


    During the quarter, NOVA Chemicals and GRUPO IDESA signed binding
agreements to form a cashless 50:50 joint venture in Mexico, called
NOVIDESA, SA de CV. The joint venture, which plans to be a market
leader in high-value EPS applications primarily targeted to the
construction market in Mexico, commenced operations on Oct. 1, 2005.

    European Styrenic Polymers

    On Oct. 1, 2005 the NOVA Innovene joint venture in Europe
commenced operations.
    On Oct. 11, 2005, NOVA Innovene announced it will permanently
shutdown an EPS plant in Carrington, UK which had previously been
idled, and permanently cease EPS production at its Berre, France
plant. The two rationalizations will remove nearly 30% of NOVA
Innovene's EPS capacity, 310 million pounds per year, and
approximately 10% of Western European industry capacity. This action
represents the first step toward achieving a minimum of $40 million in
expected synergies identified by the joint venture.

    European-SPS

    European SPS volume was up 1% from the second quarter.

    The weighted-average European SPS benchmark price declined by
approximately 3 cents per pound from the second quarter.
    NOVA Chemicals announced two price increases totaling 9 cents per
pound:



  2005 Effective Date   Price Increase Announcements
  Sept. 1               +4 cpp
  Oct. 1                +5 cpp


    Expandable Polystyrene (EPS)

    European EPS volumes increased 23% as demand strengthened in
anticipation of increased pricing.

    In Europe, EPS prices fell 6% on average over the quarter.

    NOVA Chemicals announced two price increases totaling 9 cents per
pound including:



   2005 Effective Date  Price Increase Announcements

   Oct. 1               +6 cpp


    Performance Products

    Styrenics Performance Products include products such as ARCEL
specialty foam resins; DYLARK resins for automotive and food
packaging; ZYLAR resins for food, medical and industrial packaging;
and EPS Silver resins for building and construction products.(2)
Styrenics Performance Products volumes for the quarter were 24 million
pounds, approximately the same as third quarter 2004.
    There were several Performance Products developments during the
quarter including:

    --  NOVA Chemicals entered into a long-term agreement with Loyal
        Chemical Industrial Corporation to manufacture ARCEL moldable
        foam resin near Shanghai, China. The agreement is a component
        of NOVA Chemicals' plan to expand manufacturing capacity for
        ARCEL from 30 million to 100 million pounds annually by the
        end of 2006.

    --  NOVA Chemicals signed a joint development agreement with
        Dietrich Metal Framing, a Worthington Industries company, to
        commercialize innovative construction products that combine
        light gauge steel framing and with EPS.

    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

(1) See Consolidated Statement of Net Income (Loss) and Reinvested
    Earnings on page 16 and Supplemental Measures on page 12. 


    NOVA Chemicals' net debt to total capitalization ratio was 53.2%
at Sept. 30, 2005. Cash on hand at the end of the third quarter was
$97 million, down from $216 million at the end of the second quarter,
primarily as a result of debt reduction.
    NOVA Chemicals' funds from operations were $35 million for the
third quarter of 2005, down from $41 million in the second quarter.
    Operating working capital decreased by $96 million in the third
quarter of 2005 compared to a $93 million decrease in the second
quarter of 2005. This decline was related primarily to lower inventory
levels associated with the Corunna turnaround partially offset by
higher feedstock costs.
    NOVA Chemicals measures the effectiveness of its working capital
management through Cash Flow Cycle Time (CFCT). See Supplemental
Measures on page 12. 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 to
determine which portion of changes in working capital results from
factors other than price movements. CFCT was 29 days as of Sept.
30, 2005 down from 34 days as of June 30, 2005, primarily due to lower
inventory.
    Capital expenditures were $102 million in the third quarter of
2005, compared to $115 million in the second quarter and $60 million
in the third quarter of 2004. The increase from the third quarter is
primarily related to the Corunna flexi-cracker plant modernization
project and the Bayport expansion project.
    Selling, general and administrative expenses (SG&A) increased by
$68 million from the second quarter, and was up $1 million from the
third quarter of 2004. This third quarter increase was primarily due
to the mark-to-market cost of stock-based compensation. NOVA Chemicals
stock price dropped by $12.39 per share in the second quarter and
increased by $6.24 per share in the third quarter causing a
quarter-over-quarter swing in SG&A costs of $65 million.

    Financing

    NOVA Chemicals has a $375 million revolving credit facility,
expiring June 30, 2010. As of Sept. 30, 2005, NOVA Chemicals has
utilized $62 million of the revolving credit facility in the form of
operating letters of credit. As of Oct. 18, 2005, the company utilized
$90 million of the facility, $65 million of which is in the form of
letters of credit. NOVA Chemicals continues to comply with all
financial covenants under the facility.
    As of Sept. 30, 2005, $285 million was sold under the accounts
receivable securitization programs compared to $243 million as of June
30, 2005.
    In Sept. 2005, $100 million of 7%, 10-year notes matured and
were retired for cash, and a $19 million lease for new Corunna
compressors was finalized for a net debt reduction of $81 million. In
May 2006, $300 million of 7% medium-term notes will mature.
    During Sept. 2005, the certificate of incorporation of our
subsidiary, NOVA Chemicals Inc., was amended to remove the conversion
feature that allowed the holders of the retractable preferred shares,
under certain circumstances, to convert the preferred shares to NOVA
Chemicals' common shares. Accordingly, the preferred shares will no
longer have an impact on diluted earnings per share.

    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 NOVA Chemicals uses FIFO, a
portion of the second quarter feedstock purchases flowed through the
income statement in the third quarter. June benzene prices were $2.30
per gallon increasing to $2.75 per gallon in Sept. Sept. NYMEX natural
gas pricing was higher than June pricing by $3.88 per mmBTU, while
crude oil increased from $56.42 per barrel in June to $59.03 per
barrel in July. Minimal purchases were made in Aug. and Sept. in
anticipation of the Corunna plant turnaround in Sept. 2005. We
estimate that net income would have been about $13 million lower in
the third quarter had NOVA Chemicals used the LIFO method of
accounting. Had Corunna been at normal inventory levels the impact
would have been approximately $23 million.
    We estimate that net income in the second quarter would have been
about $23 million higher had NOVA Chemicals used the LIFO method of
accounting. See Causal Analysis on page 15.

    Feedstock Derivative Positions

    NOVA Chemicals maintains a derivatives program to manage risk
associated with feedstock purchases. The after-tax gain from natural
gas, benzene and crude oil positions realized in the third quarter of
2005 was $1 million compared to an $8 million gain in the second
quarter.
    In addition, NOVA Chemicals is required to record on its balance
sheet the market value of any outstanding derivative positions that do
not qualify for hedge accounting treatment. The gain or loss resulting
from changes in the market value of these derivatives is recorded
through earnings each period. The mark-to-market impact in the third
quarter of our outstanding feedstock derivative portfolio was an $11
million after-tax gain compared to a $9 million after-tax loss in the
second quarter.

    Supplemental Measures

    In addition to providing measures in accordance with Canadian
Generally Accepted Accounting Practices (GAAP), NOVA Chemicals
presents certain supplemental measures as follows:

    --  EBITDA - defined on page 13

    --  Average capital employed - defined on page 2

    --  CFCT - defined on page 11

    --  After-tax return on capital employed - defined on page 2

    --  Net debt to total capitalization - defined on page 10

    --  Net income (loss) from the businesses - total net income or
        loss from the Olefins/Polyolefins and Styrenics businesses,
        which equals NOVA Chemicals' net income less corporate and
        other items (see page 1)

    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 Net Income (Loss) and
Reinvested Earnings by adding to net income (loss) interest expense,
income taxes, depreciation and amoritization, other gains and losses,
and restructuring charges. Segment EBITDA is determined as segment
operating income or loss before depreciation and amortization.

(1) NOVA Chemicals has two cash settled stock-based incentive
    compensation plans that are marked-to-market with changes in the
    value of the common stock price. In the first quarter of 2004 the
    stock-based compensation plan was amended to price equity
    appreciation units using NYSE values. The NYSE market price on
    Sept. 30, 2005, was $36.80 U.S. In addition, NOVA Chemicals
    maintains a profit sharing program available to most employees
    based on the achievement of shareholder return on equity targets.
    The calculation of stock-based compensation and profit sharing
    expense each quarter is dependent upon a number of variables. One
    variable is NOVA Chemicals' common share price. During the third
    quarter of 2005, the share price rose by $6.24 thereby increasing
    our liability under the stock-based compensation programs.
    Accordingly, a $14 million after-tax expense was recorded in
    earnings during the quarter. We are also required to record an
    expense for our estimate of profit sharing and stock-based
    compensation earned by employees during the quarter. NOVA
    Chemicals accrues profit sharing based on an evaluation of
    expected results versus target results. As a consequence of our
    most recent review of our ability to achieve the minimum return on
    equity targets required to trigger a profit share payout, we have
    reversed the amounts previously accrued in 2005. This resulted in
    an after-tax recovery of $6 million in the quarter. We accrue
    stock-based compensation expense over the vesting periods in which
    employees earn the units. The amount of expense is also impacted
    by the number of units redeemed during the quarter and the price
    at which they are redeemed. The after-tax amount of stock-based
    compensation expense in the third quarter of 2005 related to these
    items was $2 million.
(2) NOVA Chemicals accrued a non-cash expense of $15 million after-tax
    related to its share of estimated incremental costs in the
    insurance pools in which it participates. NOVA Chemicals is one of
    many participants in OIL and sEnergy - two mutual insurance
    companies formed to insure against catastrophic risks. Due to
    recent losses incurred by OIL and sEnergy that are related to
    participants other than NOVA Chemicals, the company will be
    required to pay higher future premiums.
(3) NOVA Chemicals recorded a charge of $75 million after-tax
    primarily as a result of a NOVA-Innovene joint venture decision to
    cease EPS production at Berre, France and permanently shutdown the
    EPS plant at Carrington, UK. The benefit of tax losses in France
    and obsolete assets associated with the Corunna modernization were
    written off and also included in this charge (see Note 8 to the
    consolidated financial statements).


    NOVA Chemicals' share price on the New York Stock Exchange (NYSE)
rose to U.S. $36.80 at Sept. 30, 2005 from U.S. $30.56 at June 30,
2005. NOVA Chemicals' share value increased 20% for the quarter ending
Sept. 30, 2005 on the NYSE and 14% on the Toronto Stock Exchange
(TSX), while peer chemical companies' share values declined 7% on
average and the S&P Chemicals Index decreased 6%. The S&P/TSX
Composite Index was up 11% and the S&P 500 was up 3% in the third
quarter. As of October 18, 2005, NOVA Chemicals' share price was U.S.
$37.06, up 1% from Sept. 30, 2005. The S&P Chemicals Index was down 2%
in the same period.
    In the third quarter, approximately 46% of trading in NOVA
Chemicals' shares took place on the TSX and 54% of trading took place
in the U.S.

    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.

    The above table is provided to describe significant items
affecting the variance in net income (loss) from quarter to quarter.
    NOVA Chemicals had higher margins in the third quarter because it
uses FIFO-based accounting versus LIFO-based. The additional margin
provided by FIFO-based accounting is partially offset by margin
erosion caused by an increase in feedstock prices from June to
Sept. which was not fully realized in higher selling prices. The
overall quarter-to-quarter gain in margin was $7 million, before the
effect of second quarter unusual events and lower profit sharing.
    Second quarter unusual events included the power outage at the
Corunna, Ontario flexi-cracker, the ethane feedstock interruption to
the Joffre, Alberta site and the insurance accrual related to NOVA
Chemicals' share of anticipated incremental future costs in the
insurance pools in which it participates. The after-tax impact of
these events totaled $39 million in the second quarter and $21 million
in the third quarter, resulting in approximately $18 million higher
earnings quarter-over-quarter.
    In the third quarter, NOVA Chemicals took a non-cash write-down of
$75 million primarily as a result of a decision by the NOVA Innovene
joint venture to cease EPS production at Berre, France and permanently
shutdown the EPS plant at Carrington, UK.
    Differences in the amount of profit sharing and stock-based
compensation accruals from quarter to quarter account for the
remaining increase in net loss from the second quarter to third
quarter.

    Notes to Consolidated Financial Statements

    (unaudited, millions of U.S. dollars, except per share amounts
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, 2004.
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, 2004 on pages 75 to 79 of the 2004 Annual Report,
except as noted below:
    Accounting for Financial Instruments with Characteristics of Both
Liabilities and Equity
    The CICA implemented new accounting standards, which harmonize
accounting standards with U.S. GAAP for some types of mandatorily
redeemable shares and other financial instruments. Beginning on Jan.
1, 2005, these instruments are required to be classified, on a
retroactive basis, as liabilities rather than equity. As a result, the
preferred shares of NOVA Chemicals' subsidiary, NOVA Chemicals Inc.,
have been classified as debt. In addition, any dividends associated
with these preferred shares have been reclassified to interest expense
reducing net income by $2 million in the third quarter of 2005, $2
million in the second quarter of 2005 and $1 million in the third
quarter of 2004. All prior periods have been restated.

(1) Certain prior year amounts have been restated to conform with
the presentation adopted in 2004 due to new Canadian GAAP disclosure
requirements.


    The expected long-term rate of return on plan assets is 7.5% in
2005.

    Employer Contributions

    NOVA Chemicals contributed $17 million to its defined benefit
pension plans and $2 million to its defined contribution plans in the
third quarter of 2005 ($32 million and $6 million in the nine months
ended Sept. 30, 2005).

    June 30, 2004, income taxes are being recorded on the liability
    method.

A total of 4.7 million stock options have been excluded from the
computation of diluted earnings per share for the quarter ended Sept.
30, 2005. As of Sept. 30, 2005, the fully diluted share count was
82,335,363 million. A total of 8.5 million retractable preferred
shares and 4.7 million stock options were excluded in the quarter
ended June 30, 2005. No retractable preferred shares or stock options
were excluded from the computation of diluted earnings per share for
the quarter ended Sept. 30, 2004. 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 were dilutive prior to Sept. 2005 if our
earnings per share was greater than the preferred share dividend
divided by the number of shares issued on conversion. As of Sept. 30,
2005, the retractable preferred shares are no longer convertible to
NOVA Chemicals' common stock and therefore are no longer a dilutive
factor in the earnings per share calculation. No restatements were
made to prior periods.

(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 largely 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) On Jan. 1, 2004, NOVA Chemicals adopted the CICA standard for
    expensing of stock options. 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.
(5) 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 included in net income.
(6) 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.
(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) See Note 1 on page 19 for change in accounting policy related to 
    financial instruments.


    8. Restructuring Charges

    On Oct. 1, 2005, NOVA Chemicals and Innovene combined their
European polystyrene businesses into a 50:50 joint venture known as
NOVA Innovene. In accordance with Canadian generally accepted
accounting procedures, NOVA Chemicals will be accounting for the joint
venture on a proportionate consolidation basis.
    On Oct. 11, 2005, NOVA Innovene announced it plans to cease EPS
production at Berre, France and permanently shutdown the EPS plant at
Carrington, UK. Accordingly, NOVA Chemicals has written down the value
of the plants on its books to zero as of Sept. 30, 2005. The amount of
the write-down was $76 million ($60 million after-tax). The company
also reduced the recorded benefit of certain tax loss carry-forwards
by $9 million, as the likelihood of their utilization is reduced as a
result of the formation of the joint venture and closure of the
plants.
    Certain other non-productive assets were written off amounting to
$9 million ($6 million after-tax). The total amount of the
restructuring charge is $85 million $75 million after-tax).
