RESTRUCTURING AND COST REDUCTION

NOVA Chemicals has targeted $125 million per year of company-wide cost
savings by the end of 2007 related to: the June 26, 2006 restructuring
announcement; NOVA Innovene synergies; and the expiry of styrene monomer
contracts. By the end of the third quarter, NOVA Chemicals took the necessary
actions to achieve a cost savings rate of $69 million per year.

North American Restructuring

On June 26, 2006, NOVA Chemicals announced plans to restructure its North
American operations to better align resources and reduce costs. A separate
business unit, named STYRENIX, was created to hold the NOVA Chemicals' styrene
monomer and solid polystyrene assets in North America as well as NOVA
Chemicals' interest in the European 50:50 joint venture with INEOS. As part of
this restructuring, a company-wide cost reduction target was set for $65
million per year by the end of 2006. This savings target includes
approximately $35 million per year of savings in the core businesses and $30
million per year of savings in STYRENIX.

NOVA Chemicals reached a North American cost-reduction rate of $52
million per year by the end of the third quarter of 2006, including $13
million per year in savings from the Chesapeake, VA, site closure in June
2006, $35 million in company-wide cost reductions and a $4 million reduction
in depreciation. Total cost reduction rates are expected to be at $65 million
per year by the first quarter of 2007 and at $69 million per year by the first
quarter of 2008.

In the third quarter of 2006, a restructuring charge of $53 million
before-tax ($33 million after-tax) was recorded related to severance, pension
and other employee-related costs.

NOVA Innovene

Upon start up in October 2005, NOVA Innovene, NOVA Chemicals' European
joint venture with INEOS, targeted synergy savings of $40 million per year
within 3 years. In the first quarter of 2006, the target was revised upward to
$60 million per year within 2 years. At this time, NOVA Innovene is on track
to exceed the revised target by the end of the fourth quarter of 2006, well
ahead of the shortened timeline. NOVA Chemicals receives 50% of the benefit of
the total cost savings.

By the end of the third quarter of 2006, NOVA Chemicals realized cost
savings of $17 million. In the fourth quarter, NOVA Chemicals expects to
realize additional savings related to the Carrington, UK and the Berre, France
plant closures, bringing the annual run rate to $33 million.

On July 25, 2006, NOVA Innovene announced plans to permanently close its
Carrington, UK, solid polystyrene facility in October 2006. Accordingly, NOVA
Chemicals fully wrote down the value of the plant as of Sept. 30, 2006. NOVA
Chemicals incurred a charge of $56 million before-tax ($46 million after-tax),
$8 million of which is related to employee severance and departure costs and
the balance due to non-cash asset write-downs.

Styrene Contract Expiration

NOVA Chemicals is required to purchase up to 1 billion pounds per year of
styrene monomer as part of two supply contracts. NOVA Chemicals estimates that
these contracts create $30 million per year of higher costs. The contracted
styrene monomer is more costly than its own production, and at times, has
forced NOVA Chemicals to reduce operating rates at its own facilities.

The first of the two supply contracts (400 million pounds per year)
expires on December 31, 2006 and will save an estimated $22 million per year
starting Jan. 1, 2007. The second supply contract (up to 600 million pounds
per year) will expire on December 31, 2007 and will save, at current styrene
economics, an estimated $8 million per year starting Jan. 1, 2008.

Review of Operations

Olefins/Polyolefins

The Olefins/Polyolefins business unit reported net income of $123 million
in the third quarter of 2006. Second quarter net income was $151 million,
including $60 million of Canadian tax rate reductions. Third quarter EBITDA of
$255 million is $49 million higher than the second quarter and is the highest
quarterly EBITDA in NOVA Chemicals' eight-year history as a publicly traded
company. The quarter-over-quarter improvement in EBITDA was primarily related
to margin improvement resulting from polyethylene and ethylene price increases
which outpaced higher feedstock costs and lower polyethylene volumes.

Ethylene and Feedstocks

USGC ethylene benchmark prices averaged 51 cents per pound in the third
quarter of 2006 compared to 47 cents per pound in the second quarter.

Quarter-over-quarter, the average price of NYMEX contract natural gas was
down 4% to $6.53 per mmBTU and the average USGC ethane price was up 12% to 76
cents per gallon. USGC ethane prices averaged 189% of NYMEX natural gas cash
prices, up from an average of 157% in the previous quarter. The average AECO
cash natural gas price of $5.03 per mmBTU in the third quarter was 6% lower
than the second quarter.

The Alberta Advantage averaged 17 cents per pound of cash cost of
ethylene production in the third quarter of 2006, up from 14 cents per pound
in the second quarter. The advantage was higher in the third quarter due to
both an increase in USGC ethane prices and a decrease in Alberta ethane costs.
NOVA Chemicals uses ethylene produced at its Joffre, Alberta, facility to
produce approximately 65% of its total polyethylene.

The price of WTI crude oil averaged $70.48 per barrel in the third
quarter, essentially flat from the second quarter. WTI crude prices increased
from second quarter levels in July and August but fell sharply in September.
NOVA Chemicals' average crude oil costs increased 7% during the quarter due to
its use of FIFO inventory accounting. This increase in crude oil feedstock
cost was offset by higher co-product revenues from the Corunna flexi-cracker.

Polyethylene

Third quarter polyethylene results improved from the second quarter as
higher margins more than offset reduced volumes.

NOVA Chemicals' total polyethylene sales volume for the third quarter was
800 million pounds, down 4% from the previous quarter. Volumes declined in
September as customers consumed inventory. International sales represented 10%
of total polyethylene sales in the third quarter, essentially the same as the
second quarter.

North American producer sales, as reported by the American Plastics
Council (APC), declined by 8% in the third quarter relative to the second
quarter of 2006. The APC also reported North American producer operating rates
averaged 92% in the third quarter. Producer inventories rose to 47 days of
sales versus a 45-day five-year average. NOVA Chemicals finished the third
quarter with 20 days of polyethylene inventory, down from 22 days at the end
of the second quarter.

The average butene liner benchmark polyethylene price in the third
quarter was 69 cents per pound, up 6 cents per pound from the second quarter.

Advanced SCLAIRTECH

Sales of Standard and Performance polyethylene products, manufactured
using Advanced SCLAIRTECH technology, reached a record high of 224 million
pounds, 9% higher than the second quarter. Third quarter market conditions
supported a product mix that resulted in sales volumes in excess of the
plant's 213 million pound quarterly nameplate capacity.

Third quarter sales of polyethylene Performance Products manufactured
using Advanced SCLAIRTECH technology were 102 million pounds, down 44 million
pounds from the second quarter due to a quality issue that has been resolved
and an opportunistic switch to higher margin standard product production.

Third Quarter 2006 Versus Third Quarter 2005

Net income of $123 million in the third quarter of 2006 was up from net
income of $26 million in the third quarter of 2005, due to increased margins
and volumes and the impact of 2005 outages.

First Nine Months 2006 Versus First Nine Months 2005

Net income for the first nine months of 2006 was $344 million, up from
$195 million for the first nine months of 2005, primarily related to price
increases that more than offset higher feedstock costs. Also, polyethylene
sales volumes in the first nine months of 2006 were 8% greater than the first
nine months of 2005 due to outages that occurred in 2005.

Review of Operations

Performance Styrenics

The Performance Styrenics business unit reported a net loss of $5 million
in the third quarter of 2006 compared to a net loss of $4 million in the
second quarter. The quarter-over-quarter decline in earnings was primarily
related to change in sales mix in North American expandable polystyrene (EPS).

North American EPS

North American EPS sales volume decreased by 8% from the second quarter
to the third quarter due to reduced demand in produce packaging. During the
third quarter, NOVA Chemicals implemented a price increase of 4 cents per
pound.

Styrenic Performance Products

Styrenic Performance Products sales volumes were 10% greater than the
prior quarter, driven by growth in ARCEL(R) and ZYLAR(R) resin sales.

During the third quarter, NOVA Chemicals announced the start-up of a
facility in Ningbo, China, a venture with Loyal Chemical. The facility
provides new finishing capacity for ARCEL moldable foam resin to support
growing Asian markets.

In addition, NOVA Chemicals entered into a 50:50 joint venture announced
on July 20, 2006 with Dietrich Metal Framing to develop and manufacture
durable, energy-saving composite construction products and systems. These
systems combine NOVA Chemicals' EPS technology with Dietrich's light-gauge
steel framing expertise.

Third Quarter 2006 Versus Third Quarter 2005

The Performance Styrenics business unit had a net loss of $5 million in
the third quarter of 2006, compared to a net loss of $1 million in the third
quarter of 2005. The impact of higher feedstock costs more than offset the
increase in prices and sales volumes.

First Nine Months 2006 Versus First Nine Months 2005

The net loss for the first nine months of 2006 was $15 million, compared
to a net loss of $7 million for the first nine months of 2005 as lower EPS
margins were only partially offset by higher sales volumes.

NOVA Chemicals' ability to implement announced price increases depends on
many factors that may be beyond its control. See Forward-Looking Information
on page 15.

Review of Operations

STYRENIX

The STYRENIX business unit reported a net loss of $35 million in the
third quarter of 2006, a 22% improvement over the $45 million net loss
reported in the second quarter. The quarter-over-quarter improvement in
earnings was related to improved NOVA Innovene results from further cost
reduction and some margin expansion.

Styrene Monomer

Styrene monomer margins were up in the third quarter as price increases
outpaced increases in feedstock costs. Styrene monomer prices rose to $0.70
per pound from $0.62 per pound in the second quarter. The third quarter
average benzene price increased to $3.71 per gallon up from $3.02 per gallon
in the second quarter. Benchmark ethylene prices averaged 51 cents per pound,
up from 47 cents per pound in the second quarter.

Third-party styrene monomer sales volumes in the third quarter were
essentially flat compared with the second quarter. In mid-July 2006, the
Bayport, TX plant re-started after having been idled since May 4, 2006 due to
the ethylene force majeure declared by Huntsman Corporation and limited
ethylene availability on the USGC.

NOVA Chemicals implemented 6 cents per pound of styrene monomer price
increases in the third quarter. An additional 6 cents per pound price increase
was announced to be effective Oct. 1.

North American Solid Polystyrene (SPS)

North American SPS sales volume increased by 1% in the third quarter
compared to the second quarter due to sales to new customers. North American
benchmark SPS prices increased by approximately 9 cents per pound from the
second quarter.

NOVA Chemicals implemented a total of 8 cents per pound of SPS price
increases during the third quarter. A 5 cents per pound price increase was
announced to be effective Oct. 1.

NOVA Innovene

In the third quarter, NOVA Innovene reported positive EBITDA, before NOVA
Chemicals' corporate charges. NOVA Innovene was EBITDA positive, after NOVA
Chemicals' corporate charges, in September of 2006 for the first time since
the joint venture started in October 2005.

SPS sales volumes for NOVA Innovene were down 9% from the second quarter,
in line with the Western European market.

EPS sales volumes for NOVA Innovene were up 2% from the second quarter.
EPS producer inventories remained low at the end of the third quarter. Margins
expanded in the third quarter as price increases outpaced higher feedstock
costs. The European EPS benchmark price increased by approximately 14 cents
per pound from the second quarter.

Third Quarter 2006 Versus Third Quarter 2005

The STYRENIX business unit had a net loss of $35 million in the third
quarter of 2006, compared to a net loss of $56 million in the third quarter of
2005. Higher prices more than offset higher feedstock costs and the decrease
in sales volume. Cost reduction programs were also a significant factor.

First Nine Months 2006 Versus First Nine Months 2005

The STYRENIX net loss for the first nine months of 2006 was $119 million,
compared to a net loss of $147 million for the first nine months of 2005, due
to margin expansion in styrene monomer and European EPS, as well as cost
reduction.

NOVA Chemicals' ability to implement announced price increases depends on
many factors that may be beyond its control. See Forward-Looking Information
on page 15.

(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 November 2005, NOVA Chemicals
 entered into a three-year hedging arrangement that effectively
 neutralizes the mark-to-market impact on the stock-based incentive
 compensation plans. In addition, NOVA Chemicals maintains a profit
 sharing program available to most employees based on the achievement
 of shareholder return on equity targets. Stock-based compensation
 also includes the amount expensed related to the fair value of stock
 options earned by employees during the period.
(2) In the third quarter of 2006, NOVA Chemicals accrued $53 million
 ($33 million after-tax) of restructuring costs related to severance,
 pension and other employee-related costs associated with the North
 American restructuring announced on June 26, 2006. In addition, NOVA
 Chemicals accrued $56 million ($46 million after-tax) related
 primarily to the non-cash asset write-downs for the Carrington, UK
 solid polystyrene facility closure. In the second quarter of 2006,
 NOVA Chemicals accrued $1 million (before-tax) of restructuring costs
 related to actions taken by NOVA Innovene. In the first quarter of
 2006, NOVA Chemicals accrued $15 million ($10 million after-tax)
 related to severance costs for the Chesapeake, VA plant site closure.
 In the third quarter of 2005, NOVA Chemicals recorded a charge of $85
 million ($75 million after-tax) primarily as a result of NOVA
 Innovene's 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.
(3) NOVA Chemicals is one of many participants in OIL and sEnergy -
 two mutual insurance companies formed to insure against catastrophic
 risks. NOVA Chemicals accrued $19 million ($13 million after-tax) in
 the third quarter of 2006 and $22 million ($15 million after-tax) in
 the second quarter of 2005 related to its share of estimated
 incremental costs in the insurance pools in which it participates.
 Due to losses incurred by OIL and sEnergy that are related to
 participants other than NOVA Chemicals, NOVA Chemicals was required
 to pay higher premiums. The third quarter charges are related to
 sEnergy which is in the process of closing operations.
(4) See page 13 for description.
(5) Beginning in 2006, NOVA Chemicals began classifying stock option
 expense and mark-to-market adjustments on feedstock derivative
 positions as corporate items as they are non-cash items and are not
 relevant in measuring business performance. Previously these amounts
 were allocated to the Olefins/Polyolefins and Styrenics business
 units. Prior periods have been restated to conform with the new
 presentation.
>>

Supplemental Measures

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

--  Adjusted EBITDA - This measure, defined on page 2, is provided to
assist investors in determining the ability of NOVA Chemicals to generate cash
from operations. Segment adjusted EBITDA is determined as segment operating
income or loss before depreciation and amortization.

--  After-tax return (loss) on capital employed - defined on page 2

--  Average capital employed - defined on page 2

--  Core Business income - Net income (loss) from the business units less
net income (loss) from the STYRENIX business unit

--  CFCT - defined on page 12

--  Net current debt - current debt less restricted cash and other assets

--  Net debt to total capitalization - defined on page 11

--  Net income (loss) from the business units - total net income or loss
from the Olefins/Polyolefins, Performance Styrenics and STYRENIX business
units, which equals NOVA Chemicals' net income less corporate and other items
(see page 1). This measure highlights the ongoing performance of the business
units without considering one-time charges events or other items which are not
driven by the business.

--  Net tangible asset coverage on long-term debt - defined on page 11

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.

>>

NOVA Chemicals' funds from operations were $76 million for the third
quarter of 2006, down from $101 million in the second quarter. Operating
working capital increased by $65 million, primarily as a result of higher
inventories.

NOVA Chemicals measures the effectiveness of its working capital
management through Cash Flow Cycle Time (CFCT). See Supplemental Measures on
page 10. CFCT measures working capital from operations (excluding NOVA
Innovene) 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 35 days as of Sept. 30, 2006, and 30 days
as of June 30, 2006.

Capital expenditures were $47 million in the third quarter of 2006,
compared to $64 million in the second quarter and $102 million in the third
quarter of 2005. Capital spending was down from the same time last year due to
reduced expenditures related to the Corunna flexi-cracker modernization
project.

Selling, general and administrative (SG&A) costs were $27 million lower
than in the third quarter of 2005 and $19 million higher on a year-to-date
basis largely due to the mark-to-market impact from stock-based compensation
being recorded in 2005. In 2006, this exposure has been hedged.

Interest expense was higher by $15 million in the third quarter of 2006
compared to the third quarter of 2005 and $45 million higher on a year-to-date
basis compared to 2005 due to higher debt levels, higher interest rates and
less capitalized interest resulting from the completion of the Corunna and
Bayport projects.

Financing

NOVA Chemicals has $575 million of revolving credit facilities, which
expire on the following dates: $100 million on June 30, 2008, $375 million on
June 30, 2010 and $100 million on Mar. 12, 2011. As of Sept. 30, 2006, NOVA
Chemicals had utilized $257 million of the facilities, of which $52 million
was in the form of letters of credit. All the facilities are governed by the
same financial covenants.

On Mar. 31, 2006, NOVA Chemicals amended its debt to capitalization ratio
financial covenant from 55% to 60% for the period Mar. 31, 2006 to Sept. 30,
2006. Using the covenant methodology in the revolving credit facilities, the
debt to capitalization ratio was 53% at Sept. 30, 2006. NOVA Chemicals
continues to comply with all financial covenants under the facilities.

NOVA Chemicals also has $350 million accounts receivable programs that
will expire on June 30, 2010. As of Sept. 30, 2006, $305 million was sold
under the accounts receivable securitization programs.

Feedstock Derivative Positions

NOVA Chemicals maintains a derivatives program to manage risk associated
with feedstock purchases. In the third quarter, there was a net gain of $4
million from all Corunna feedstock derivative positions that matured; there
was no net gain or loss 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 earnings impact in the third quarter of NOVA Chemicals'
outstanding feedstock derivative portfolio was an $11 million after-tax loss
compared to an $8 million after-tax gain in the second quarter. These
mark-to-market adjustments are recorded as part of Corporate results until the
positions are realized. Once realized, any income effects are recorded in
business results.

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 Consolidated Statements of Net
Income (Loss) and Reinvested Earnings in the third quarter. The following
chart depicts the benzene, crude and natural gas prices at the end of each
quarter.

NOVA Chemicals estimates that earnings would have been about $6 million
lower in the third quarter had it used the LIFO method of accounting.

Other Information

As of Sept. 30, 2006, NOVA Chemicals' management, together with NOVA
Chemicals' President and Chief Executive Officer (CEO) and Chief Financial
Officer have evaluated the effectiveness of the design and operation of the
company's disclosure controls and procedures. Based on this evaluation, the
President and CEO have concluded that the disclosure controls and procedures
of the company are effective. There were no changes in NOVA Chemicals'
internal controls over financial reporting during the most recent fiscal
quarter that have materially affected or are reasonably likely to materially
affect NOVA Chemicals' internal control over financial reporting.

NOVA Chemicals has received a comment letter from the staff of the
Securities and Exchange Commission concerning two items relating to its annual
report on Form 40-F for the fiscal year ended December 31, 2005. One issue
relates to the amount of disclosure provided for restructuring charges which
the company has agreed to provide on a prospective basis. The other issue
relates to the number of reportable segments in NOVA Chemicals' historical
disclosures pursuant to SFAS 131. This issue has not been resolved at this
time, but NOVA Chemicals is continuing to work with SEC staff to address the
issue. The resolution of this matter will not have any impact on NOVA
Chemicals' previously reported financial position, results of operations or
cash flows.

NOVA Chemicals' share price on the New York Stock Exchange (NYSE) rose to
$30.71 at Sept. 30, 2006 from $28.79 at June 30, 2006. NOVA Chemicals' share
value increased 7% for the quarter ending Sept. 30, 2006 on the NYSE and on
the Toronto Stock Exchange (TSX). Peer chemical companies' share values
increased 2% on average and the S&P Chemicals Index increased 4%. The S&P/TSX
Composite Index was up 1% and the S&P 500 was up 5% in the third quarter. As
of

Oct. 17, 2006, NOVA Chemicals' share price was $30.28, down 1% from Sept.
30, 2006. The S&P Chemicals Index was up 2% over the same period.

In the third quarter, approximately 38% of trading in NOVA Chemicals'
shares took place on the TSX and 62% of trading took place on the NYSE and
other U.S. markets.

Forward-Looking Information

This news release contains forward-looking statements with respect to
NOVA Chemicals, its subsidiaries and affiliated companies. By their nature,
forward-looking statements require NOVA Chemicals to make assumptions and are
subject to inherent risks and uncertainties. There is significant risk that
predictions, forecasts, conclusions and projections will not prove to be
accurate, that NOVA Chemicals' assumptions may not be correct and that actual
results may differ materially from such predictions, forecasts, conclusions or
projections. Forward-looking statements for the time periods beyond 2006
involve longer-term assumptions and estimates than forward-looking statements
for 2006 and are consequently subject to greater uncertainty. NOVA Chemicals
cautions readers of this news release not to place undue reliance on its
forward-looking statements as a number of factors could cause actual results,
conditions, actions or events to differ materially from the targets,
expectations, estimates or intentions expressed in the forward-looking
statements.

The words "believe," "expect," "plan," "intend," "estimate," or
"anticipate" and similar expressions, as well as future or conditional verbs
such as "will," "should," "would," and "could" often identify forward-looking
statements. Specific forward-looking statements contained in this news release
include, among others, statements regarding: NOVA Chemicals' belief that the
progress in STYRENIX improves the prospects of a deal that will unlock the
full value of its core businesses for shareholders; NOVA Chemicals'
expectations with respect to timing, delivery and financial impact of its cost
reduction initiatives; expected financial performance in future periods,
including cost savings in NOVA Chemicals' STYRENIX business unit; and
implementation of announced price increases. With respect to forward-looking
statements contained in this news release, NOVA Chemicals has made assumptions
regarding, among other things: future oil, natural gas and benzene prices; its
ability to obtain raw materials; its ability to market products successfully
to its anticipated customers; the impact of increasing competition; and its
ability to obtain financing on acceptable terms. Some of the risks that could
affect NOVA Chemicals' future results and could cause results to differ
materially from those expressed in the forward-looking statements 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;
NOVA Chemicals ability to implement its business strategies; 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,
including customer acceptance of NOVA Chemicals' Performance Products; changes
in, or the introduction of new laws and regulations relating to NOVA
Chemicals' business, including environmental, competition and employment laws;
costs to comply with the Kyoto Protocol; loss of the services of any of NOVA
Chemicals' executive officers; uncertainties associated with the North
American, South American, European, and Asian economies; terrorist attacks;
severe weather events; and other risks detailed from time to time in the
publicly filed disclosure documents and securities commission 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.

NOVA Chemicals' forward-looking statements are expressly qualified in
their entirety by this cautionary statement. In addition, the forward-looking
statements are made only as of the date of this news release, and except as
required by applicable law, NOVA Chemicals undertakes no obligation to
publicly update these forward-looking statements to reflect new information,
subsequent events or otherwise.

Employer Contributions

NOVA Chemicals contributed $28 million, $12 million and $17 million
during the quarters ended Sept. 30, 2006, June 30, 2006 and Sept. 30, 2005,
respectively, to its defined benefit pension plans. NOVA Chemicals contributed
$2 million during each of the quarters ended Sept. 30, 2006, June 30, 2006 and
Sept. 30, 2005 to its defined contribution plans. NOVA Chemicals contributed
$50 million and $32 million during the nine months ended Sept. 30, 2006 and
Sept. 30, 2005, respectively, to its defined benefit pension plans. NOVA
Chemicals contributed $6 million during each of the nine month periods ended
Sept. 30, 2006 and Sept. 30, 2005 to its defined contribution plans.

3. Restructuring Charges

In the third quarter of 2006, NOVA Chemicals had two significant
restructuring events as follows:

1) On June 26, 2006, NOVA Chemicals announced plans to restructure its
North American operations to better align resources and reduce costs. NOVA
Chemicals will remove $65 million of costs across the organization. These
reductions include the previously announced savings of $15 million per year
from the Chesapeake, Virginia site closure.

As a result, a restructuring charge of $53 million before-tax ($33
million after-tax) for severance, pension and other employee related costs was
booked in the third quarter of 2006. Of this amount, approximately $10 million
related to one-time pension curtailment and special termination benefit
charges. Of the $43 million remaining charge, NOVA Chemicals estimates $28
million will be paid to employees by the end of 2006 with the majority of the
remainder to be paid in 2007.

2) On July 25, 2006, NOVA Innovene announced its plans to permanently
close its Carrington, UK, solid polystyrene facility in October 2006.
Accordingly, NOVA Chemicals wrote down the value of the plant on its books to
zero as of Sept. 30, 2006. NOVA Chemicals incurred a charge of $56 million
before-tax ($46 million after-tax) related primarily to non-cash asset
write-downs, however $8 million will be paid to employees in severance and
other departure costs.

In the second quarter of 2006, NOVA Chemicals accrued $1 million of
additional restructuring costs related to rationalization activities commenced
in 2005 in its European joint venture with INEOS, NOVA Innovene. These actions
will largely be complete by the end of 2006.

In the third quarter of 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 wrote 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). NOVA Chemicals 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 was $85 million ($75 million after-tax).

Included in the restructuring charges for the nine months ended Sept. 30,
2006 are severance costs of $15 million ($10 million after-tax) related to the
Chesapeake closure that were accrued in the first quarter of 2006. $1 million
of the severance costs have been paid to employees to date with the majority
of the remainder to be paid by the end of 2006.

3.4 million and 4.7 million stock options were excluded from the
computation of diluted earnings per share for the quarters ended Sept. 30,
2006 and Sept. 30, 2005, respectively, because they were anti-dilutive. No
stock options were excluded from the computation of diluted earnings per share
for the quarter ended June 30, 2006. As of Sept. 30, 2006, the fully diluted
share count was 82.6 million. 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.

7. Segmented Information

On June 26, 2006, NOVA Chemicals announced the restructuring of its
business into three units to better reflect its performance, align resources
and reduce costs. These three units are Olefins/Polyolefins, Performance
Styrenics and STYRENIX. Previously, the business was reflected in two
segments: Olefins/Polyolefins and Styrenics. Prior periods have been restated
to reflect the new operating segments.

(1) Derivative Instruments and Hedging Activities. Canadian GAAP does not
require the recognition of derivative instruments on the consolidated balance
sheet at fair values, unless the derivative instrument does not qualify for
hedge accounting under Canadian Accounting Guideline 13, Hedging Relationships
(AcG-13). Non-qualifying derivatives are adjusted to fair value through income
(loss). Under U.S. GAAP, entities must follow the recommendations of Statement
of Financial Accounting Standards (SFAS) No. 133, Accounting for Derivative
Instruments and Hedging Activities, which require the recognition of all
derivatives on the balance sheet at fair value. Derivatives that are not
hedges must be adjusted to fair value through income (loss). If the derivative
is a hedge, depending on the nature of the hedge, changes in the fair value of
derivatives will either be offset against the change in fair value of the
hedged assets, liabilities, or firm commitments through earnings or recognized
in other comprehensive income until the hedged item is recognized in earnings.
For derivatives that are designated and qualify as hedging instruments, the
Corporation documents the hedging strategy, including hedging instrument and
hedged item, based on the risk exposure being hedged. Based upon the
designated hedging strategy, effectiveness of the hedge in offsetting the
hedged risk is assessed at inception and on an ongoing basis during the term
of the hedge. The ineffective portion of a derivative's change in fair value
is immediately recognized in earnings. The application of SFAS No. 133 for
U.S. GAAP reporting results in differences related to commodity-based and
other derivative instruments used by NOVA Chemicals.

(2) Inventory Costing. Canadian GAAP allows fixed overhead costs
associated with production activities to be expensed during the period whereas
U.S. GAAP requires an allocation of fixed production overhead to inventory.

(3) Start-up Costs. Canadian GAAP provides that when an entity starts up
a new facility, expenditures incurred during the pre-operating period may be
deferred when certain criteria are met. Under U.S. GAAP, all costs (except
interest on constructed assets) associated with start-up activities must be
expensed as incurred.

(4) Comprehensive Income (loss). U.S. GAAP SFAS No. 130, Reporting
Comprehensive Income, requires the presentation of a statement containing the
components of comprehensive income (loss) and the accumulated balance of other
comprehensive income. Comprehensive income includes all changes in equity
during the period including items that are not in net income (loss). This
statement is not currently required under Canadian GAAP.

(5) Cumulative Translation Adjustment. Under U.S. GAAP unrealized 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.

(6) Minimum Pension Liability. SFAS No. 87, Employer's Accounting for
Pensions, requires an employer to record an additional minimum liability (AML)
if the unfunded accumulated benefit obligation exceeds the accrued pension
liability or if there is a prepaid pension asset with respect to the plan. If
an AML is recognized, an intangible asset, in an amount not exceeding the
unrecognized prior service cost, is also recognized. The excess of the AML,
over the intangible asset, if any, is charged to other comprehensive income,
net of income tax effects.

(7) Joint Ventures. NOVA Chemicals accounts for its interests in joint
ventures using the proportionate consolidation method under Canadian GAAP. As
permitted by specific United States Securities and Exchange Commission
exemptions, adjustments to reflect equity accounting, as required under U.S.
GAAP, have not been made. The equity method would not result in any changes in
NOVA Chemicals' net income (loss) or shareholders' equity, however, all
assets, liabilities, revenue, expenses, and most cash flow items would
decrease when compared with the amounts that are presented using proportionate
consolidation.

(8) Stock-Based Compensation Plans. Under Canadian GAAP, the Employee
Incentive Stock Option Plan is measured using a fair-value-based method, while
the Equity Appreciation Plan and the Restricted Stock Unit Plan are marked to
market. U.S. GAAP, SFAS No. 123(R), Accounting for Share-Based Payment,
effective Jan. 1, 2006, requires the share-based compensation transactions to
be accounted for using a fair-value-based method, such as the Black Scholes
method used by NOVA Chemicals. This standard requires adoption using a
modified prospective application. The fair value of awards classified as
liability instruments must be remeasured subsequently at each reporting date
through the settlement date. Changes in fair value during the requisite
service period will be recognized as compensation cost over that period. The
cumulative effect of $5 million for the period prior to Dec. 31, 2005, has
been charged to reinvested earnings at Dec. 31, 2005.

New Accounting Pronouncements

Canadian GAAP

EIC 162, Stock-Based Compensation for Employees Eligible to Retire Before
the Vesting Date, requires that compensation cost for stock-based awards for
employees eligible to retire at the grant date must be recognized at the grant
date. For those employees who will become eligible to retire during the
vesting period, compensation cost should be recognized over the period from
the grant date to the date on which the employee becomes eligible to retire.
Application of this standard will result in acceleration of the recognition of
compensation expenses. This standard is effective for NOVA Chemicals fourth
quarter 2006 reporting.

CICA 3831, Non-Monetary Transactions, is effective for periods beginning
on or after Jan. 1, 2006. It requires commercially substantive non-monetary
transactions to be measured at fair value rather than the carrying amount of
the assets given up.

CICA 3855, Financial Instruments - Recognition and Measurement & CICA
3865, Hedges, are effective for fiscal years beginning on or after October 1,
2006. This statement harmonizes Canadian and US GAAP and IFRS by establishing
standards for recognition and measurement of financial assets, liabilities and
non-financial derivatives. Previous Canadian standards addressed disclosure
and presentation matters only. CICA 3865 sets standards for when and how hedge
accounting may be applied, further restricting which hedging relationships
qualify for hedge accounting.

CICA 1530, Comprehensive Income, is effective for NOVA Chemicals fourth
quarter reporting and harmonizes Canadian and US GAAP and IFRS. This statement
defines the presentation of comprehensive income and its components.
Comprehensive income includes all changes in equity during the period
including items that are not in net income (loss).

CICA 1506, Changes in Accounting Policies and Estimates, and Errors, is
effective Jan. 1, 2007 and states an entity is permitted to change accounting
policies only when it is required by a primary source of GAAP, or when the
change results in a reliable and more relevant presentation in the financial
statements.

US GAAP

FIN 48, Accounting for Uncertainty in Income Taxes, clarifies accounting
for income taxes by prescribing a minimum recognition threshold a tax position
is required to meet before being recognized. An enterprise would be required
to recognize the best estimate of a tax position if that position is more
likely than not of being sustained upon examination, based solely on the
technical merits of the position.

SFAS 154, Accounting Changes and Error Corrections, requires
retrospective application, with restatement of prior periods, for a voluntary
change in accounting principle. This standard aligns US and Canadian GAAP and
IFRS.

SFAS 158, Employers' Accounting for Defined Benefit Pension and Other
Postretirement Plans, issued on Sept. 29, 2006, amends SFAS 87 and SFAS 106,
and requires recognition of the overfunded or underfunded status of pension
and other postretirement benefit plans on the balance sheet. Under SFAS 158,
gains and losses, prior service costs and credits, and any remaining
transition amounts under SFAS 87 and SFAS 106 that have not yet been
recognized through net periodic benefit cost will be recognized in accumulated
other comprehensive income, net of tax effects, until they are amortized as a
component of net periodic cost. The measurement date, the date at which the
benefit obligation and plan assets are measured, is required to be the
company's fiscal year end. SFAS 158 is effective for publicly-held companies
for fiscal years ending after December 15, 2006, except for the measurement
date provisions, which are effective for fiscal years ending after December
15, 2008. NOVA Chemicals is currently assessing the impact that the adoption
of FAS 158 will have on NOVA Chemical's stockholders' equity at December 31,
2006. This Statement does not affect the results of operations.
