                          AAON, Inc., and Subsidiaries
                 Notes to the Consolidated Financial Statements
                               September 30, 2006
                                   (unaudited)


1.  BASIS OF PRESENTATION

The financial statements included herein have been prepared by the Company,
without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission (SEC). Certain information and footnote disclosures normally
included in financial statements prepared in accordance with accounting
principles generally accepted in the United States have been condensed or
omitted pursuant to such rules and regulations. The Company believes that the
disclosures made in these financial statements are adequate to make the
information presented not misleading when read in conjunction with the financial
statements and the notes thereto included in the Company's latest audited
financial statements which were included in the Form 10-K Report for the fiscal
year ended December 31, 2005, filed by AAON, Inc. with the SEC. In the opinion
of management, the accompanying financial statements include all normal,
recurring adjustments and estimated provisions considered necessary by
management to fairly state the results of the periods presented. Operating
results for the nine months ended September 30, 2006, are not necessarily
indicative of the results that may be expected for the year ending December 31,
2006.

Currency

Foreign currency transactions and financial statements are translated in
accordance with Statement of Financial Standards No. 52, Foreign Currency
Translations. The Company uses the U.S. dollar as its functional currency,
except for the Company's Canadian subsidiaries, which use the Canadian dollar.
Adjustments arising from translation of the Canadian subsidiaries' financial
statements are reflected in the Consolidated Statement of Stockholders' Equity.
Transaction gains or losses that arise from exchange rate fluctuations
applicable to transactions are denominated in Canadian currency and are included
in the results of operations as incurred.

New Accounting Pronouncements

FASB (Financial Accounting Standards Board) Statement 123(R), Accounting for
Stock-Based Compensation replaces FASB Statement No. 123, Accounting for
Stock-Based Compensation, and supersedes APB Opinion No. 25, Accounting for
Stock Issued to Employees. The Statement requires measurement of the cost of
employee services received in exchange for an award of equity instruments based
on the grant-date fair value of the award. The compensation cost will be
recognized over the period of time during which an employee is required to
provide service in exchange for the award. The Statement applies to all awards
granted after December 31, 2005 and to any unvested awards outstanding at
December 31, 2005. Effective January 1, 2006, the Company adopted the fair value
recognition method of Statement of Financial Accounting Standards No. 123(R)
Accounting for Stock Based Compensation (SFAS 123R), using the
modified-prospective-transition method.

FASB Statement 151, Inventory Costs, replaces Accounting Research Bulletin No.
43, Chapter 4, Inventory Pricing. The Statement requires that abnormal amounts
of idle facility expense, freight, handling costs and spoilage should be
expensed as incurred and not included in overhead as an inventory cost. The new
statement also requires that allocation of fixed production overhead costs
should be based on normal capacity of the production facilities. The Statement
was effective January 1, 2006. The adoption of this statement did not have a
material impact on the Company's Consolidated Financial Statements.

In July 2006, the FASB released FASB Interpretation No. 48, Accounting for
Uncertainty in Income Taxes, an Interpretation of FASB Statement 109. FIN 48
clarifies the accounting for uncertain tax positions as described in SFAS No.
109, Accounting for Income Taxes, and requires a company to recognize, in its
financial statements, the impact of a tax position only if that position is
"more likely than not" of being sustained on an audit basis solely on the
technical merits of the position. FIN 48 also requires qualitative and
quantitative disclosures including a discussion of reasonably possible changes
that might occur in the recognized tax benefits over the next twelve months as
well as a roll-forward of all unrecognized tax benefits. FIN 48 is effective for
fiscal years beginning after December 15, 2006. The Company is currently
evaluating the effect FIN 48 will have on the Company's Consolidated Financial
Statements.

                                      -5-


In September 2006, the FASB released SFAS No. 157, "Fair Value Measurements".
Statement 157 defines fair value and establishes a framework for measuring fair
value in generally accepted accounting principles, and expands disclosures about
fair value measurements. Although SFAS 157 applies to (and amends) the
provisions of existing authoritative literature, it does not, of itself, require
any new fair value measurements or establish valuation standards. SFAS 157 is
effective for financial statements issued for fiscal years beginning after
November 15, 2007, and interim periods within those fiscal years. Adoption of
SFAS 157 is not expected to have a material impact on the Company's Consolidated
Financial Statements.

In September 2006, the staff of the Securities and Exchange Commission issued
Staff Accounting Bulletin No. 108 (SAB 108), which provides interpretive
guidance on how the effects of the carryover or reversal of prior year
misstatements should be considered in quantifying a current year misstatement.
SAB 108 becomes effective in fiscal 2007. Adoption of SAB 108 is not expected to
have a material impact on the Company's Consolidated Financial Statements.


2.  STOCK COMPENSATION

The Company maintains a stock option plan for key employees, directors and
consultants. The Company's stock option plan provided for 2,925,000 shares of
common stock to be issued under the plan. Under the terms of the plan, the
exercise price of shares granted may not be less than 85% of the fair market
value at the date of the grant. Options granted to directors prior to May 25,
2004, vest one year from the date of grant and are exercisable for nine years
thereafter. Options granted to directors on or after May 25, 2004, vest
one-third each after 1-3 years. All other options granted vest at a rate of 20%
per year, commencing one year after date of grant, and are exercisable during
years 2-10.

Prior to January 1, 2006, the Company accounted for its nonqualified stock
options under the recognition and measurement principles of APB Opinion No. 25,
Accounting for Stock Issued to Employees, and related interpretations. Under APB
25, no stock-based employee compensation cost was reflected in net income, as
all options granted under the plan qualified for "fixed" plan accounting and had
an exercise price equal to the market value of the underlying common stock on
the date of grant. The Company had adopted the disclosure-only provisions of
Statement of Financial Accounting Standards No. 123, Accounting for Stock Based
Compensation (SFAS 123). No stock based compensation cost was recognized in the
Consolidated Statements of Income for the three and nine months ended September
30, 2005.

Effective January 1, 2006, the Company adopted the fair value recognition
provisions of Statement of Financial Accounting Standards No. 123(R) Share-Based
Payment (SFAS 123R), using the modified-prospective-transition provisions. Under
that transition method, compensation cost recognized in the first nine months of
2006 includes all share-based payments granted prior to, but not yet vested as
of January 1, 2006, and compensation cost for all share-based payments granted
subsequent to January 1, 2006. The compensation cost is based on the grant date
fair value calculated using a Black-Scholes-Merton Option Pricing Model in
accordance with provisions of Statement 123(R).

For the three and nine month periods ended September 30, 2006, the Company
recognized approximately $144,000 and $380,000, respectively, in pre-tax
compensation expense in the Consolidated Statement of Income related to the
stock option plan. The total pre-tax compensation cost related to nonvested
stock options not yet recognized as of September 30, 2006, is $1.3 million and
is expected to be recognized over a weighted-average period of 2.4 years.

                                      -6-


The effect on net income and earnings per share if the Company had applied the
fair value recognition provisions of SFAS No. 123, Accounting for Stock-Based
Compensation, to stock-based employee compensation is as follows:

3.  ACCOUNTS RECEIVABLE

The Company grants credit to its customers and performs ongoing credit
evaluations. The Company generally does not require collateral or charge
interest. The Company establishes an allowance for doubtful accounts based upon
factors surrounding the credit risk of specific customers, historical trends,
economic and market conditions and the age of the receivable. Past due accounts
are generally written off against the allowance for doubtful accounts only after
all collection attempts have been exhausted.

Accounts receivable and the related allowance for doubtful accounts are as
follows:

4.  INVENTORIES

Inventories are valued at the lower of cost or market. Cost is determined by the
first-in, first-out (FIFO) method. The Company establishes an allowance for
excess and obsolete inventories based on product line changes, the feasibility
of substituting parts and the need for supply and replacement parts. At
September 30, 2006, and December 31, 2005, inventory balances and the related
changes in the allowance for excess and obsolete inventories account are as
follows:

6.  REVOLVING CREDIT FACILITY

The Company's revolving credit facility provides for maximum borrowings of $15.2
million. Interest on borrowings is payable monthly at the Wall Street Journal
prime rate less .5% or LIBOR plus 1.6%, at the election of the Company (6.93% at
September 30, 2006). At September 30, 2006, the Company had $6.5 million in
borrowings under the revolving credit facility and no borrowings outstanding
under the revolving credit facility at December 31, 2005. In addition, the
Company has a $600,000 letter of credit that expires December 31, 2006.
Borrowings available under the revolving credit facility at September 30, 2006,
were $8.1 million. The credit facility previously required the Company to
maintain a certain financial ratio and prohibited the declaration of cash
dividends. On February 14, 2006, the Board of Directors voted to initiate a
semi-annual cash dividend of $0.20 per share to the holders of the outstanding
Common Stock of the Company as of the close of business on June 12, 2006, the
record date, payable on July 3, 2006. In conjunction with the Board's vote on
February 14, 2006, the restriction of payments of dividends was waived by the
lender and removed from the covenants with the renewal of the line of credit
July 30, 2006. At September 30, 2006, the Company was in compliance with its
financial ratio covenants. On July 30, 2006, the Company renewed the line of
credit with a maturity date of July 30, 2007.

8. STOCK REPURCHASE

Following repurchases of approximately 12% of its outstanding Common Stock
between September 1999 and September 2001, the Company announced and began its
current stock repurchase program on October 17, 2002, targeting repurchases of
up to an additional 10% (1,325,000 shares) of its outstanding stock. Through
September 30, 2006, the Company had repurchased a total of 1,257,864 shares
under the current program for an aggregate price of $22,034,568, or an average
of $17.52 per share. On February 14, 2006, the Board of Directors approved the
suspension of the Company's repurchase program.

On July 1, 2005, the Company entered into a stock repurchase arrangement by
which employee-participants in AAON's 401K Savings and Investment Plan are
entitled to have shares of AAON stock in their accounts sold to the Company to
provide diversification of their investments. Through September 30, 2006, the
Company repurchased 226,855 shares for an aggregate price of $4,698,783 or an
average price of $20.71 per share.


9. CONTINGENCIES

The Company is subject to claims and legal actions that arise in the ordinary
course of business. Management believes that the ultimate liability, if any,
will not have a material effect on the Company's results of operations or
financial position.

                                      -11-


Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations.

AAON engineers, manufactures and markets air-conditioning and heating equipment
consisting of standardized and custom rooftop units, chillers, air-handling
units, make-up units, heat recovery units, condensing units and coils.

AAON sells its products to property owners and contractors through a network of
manufacturers' representatives and its internal sales force. Demand for the
Company's products is influenced by national and regional economic and
demographic factors. The commercial and industrial new construction market is
subject to cyclical fluctuations in that it is generally tied to housing starts,
but has a lag factor of 6-18 months. Housing starts, in turn, are affected by
such factors as interest rates, the state of the economy, population growth and
the relative age of the population. When new construction is down, the Company
emphasizes the replacement market.

The principal components of cost of goods sold are labor, raw materials,
component costs, factory overhead, freight out and engineering expense. The
principal raw materials used in AAON's manufacturing processes are steel, copper
and aluminum. The major component costs include compressors, electric motors and
electronic controls.

Selling, general, and administrative ("SG&A") costs include the Company's
internal sales force, warranty costs, profit sharing and administrative expense.
Warranty expense is estimated based on historical trends and other factors. The
Company's warranty on its products is: for parts only, the earlier of one year
from the date of first use or 14 months from date of shipment; compressors (if
applicable), an additional four years, on gas-fired heat exchangers (if
applicable), 15 years, and on stainless steel heat exchangers (if applicable),
25 years.

The office facilities of AAON, Inc. consist of a 337,000 square foot building
(322,000 sq. ft. of manufacturing/warehouse space and 15,000 sq. ft. of office
space) located at 2425 S. Yukon Avenue, Tulsa, Oklahoma (the "original
facility"), and a 563,000 square foot manufacturing/warehouse building and a
22,000 square foot office building (the "expansion facility") located across the
street from the original facility at 2440 S. Yukon Avenue. The Company utilizes
39% of the expansion facility and the remaining 61% is leased to a third party.
The operations of the Longview, Texas plant are conducted in a plant/office
building at 203-207 Gum Springs Road in Longview, Texas, containing 258,000
square feet (251,000 sq. ft. of manufacturing/warehouse and 7,000 sq. ft. of
office space). In 2004 and 2005, AAON Coil Products purchased an additional 15
acres of land for future expansion. The Company's operations in Burlington,
Ontario, Canada, are located at 279 Sumach Drive, consisting of an 82,000 sq.
ft. office/manufacturing facility on a 5.6 acre tract of land.

Results of Operations

Net sales increased $16.1 million (33.3%) to $64.2 million from $48.1 million
for the three months ended September 30, 2006, and $40.6 million (29.8%) to
$176.9 million from $136.3 million for the nine months ended September 30, 2006,
compared to the same periods in 2005. Increased sales were attributable to an
increase in volume of product sold related to an improvement of the commercial
and industrial construction industry, and an increased demand for the Company's
new and redesigned products.

Gross profit increased $5.0 million (57.2%) to $13.6 million from $8.6 million
for the three months ended September 30, 2006, and increased $7.0 million
(26.0%) to $34.1 million from $27.1 million for the nine months ended September
30, 2006, compared to the same periods in 2005. Gross margins were 21.2%
compared to 18.0% for the three months ended September 30, 2006 and September
30, 2005, respectively, and were 19.3% compared to 19.9% for the nine months
ended September 30, 2006 and September 30, 2005, respectively. The increase in
gross profits and earnings was due primarily to increased volume of product sold
and price increases. The increase in margins was attained despite the continued
high costs for steel, copper and aluminum, and an increase in manufacturing
expense and inbound and outbound transportation charges related to the increase
in fuel costs.

Steel, copper and aluminum are high volume materials used in the manufacturing
of the Company's products, which are obtained from domestic suppliers. The
Company experienced increased copper and steel prices during the first six
months of the year with some stabilization of copper pricing during the second
quarter that continued through the third quarter. The Company also purchases
from other domestic manufacturers certain components, including compressors,
electric motors and electrical controls used in its products.
 The suppliers of these components are significantly affected by the rising raw
material costs as steel, copper and aluminum are used in the manufacturing of
their products. The Company is also experiencing price increases from component
part suppliers. The Company attempts to limit the impact of price increases on
these materials by entering into cancelable fixed price contracts with its major
suppliers for periods of 6-12 months.

Selling, general and administrative expenses increased $1.6 million (35.0%) to
$6.0 million from $4.4 million for the three months ended September 30, 2006,
and increased $2.4 million (18.4%) to $15.4 million from $13.0 million for the
nine months ended September 30, 2006, compared to the same periods in 2005. The
increase was due primarily to an increase in warranty and sales expenses related
to increased sales, professional fees and employee benefits, salaries and stock
option compensation expense.

Financial Condition and Liquidity

Net accounts receivable increased $13.9 million to $46.3 million at September
30, 2006 from $32.4 million at December 31, 2005, due to the increase in sales.

Inventories increased $6.0 million to $29.7 million at September 30, 2006,
compared to $23.7 million at December 31, 2005, due to the timing of procurement
of raw material and purchased parts required to accommodate increased sales.

Accounts payable and accrued liabilities increased $11.2 million to $40.7
million at September 30, 2006, compared to $29.5 million at December 31, 2005,
due primarily to an increase in expenses and timing of payments to vendors.

The Company generated $11.2 million and $6.5 million cash from operating
activities during the nine months ended September 30, 2006, and September 30,
2005, respectively. The increase in 2006 related primarily to an increase in net
income and the timing of accounts payable payments and receipt of accounts
receivable.

Cash flows used in investing activities were $14.8 million for the nine months
ended September 30, 2006, and $5.7 million for the nine months ended September
30, 2005. Cash flows used in investing activities in 2006 and in 2005 were
related primarily to capital expenditures for additions of machinery and
equipment.

Cash flows provided by financing activities were $3.1 million and cash flows
used in financing activities were $1.5 million during the nine months ended
September 30, 2006, and September 30, 2005, respectively. The cash flows
provided by financing activities in 2006, were due primarily to borrowings under
the revolving credit facility. On February 14, 2006, the Board of Directors
voted to initiate a semi-annual cash dividend of $0.20 per share to the holders
of the outstanding Common Stock of the Company as of the close of business on
June 12, 2006, the record date, payable on July 3, 2006. The dividend payment of
$2.4 million was financed primarily by the revolving credit facility on June 30,
2006. On July 1, 2005, the Company entered into a stock repurchase arrangement
by which employee-participants in AAON's 401K Savings and Investment Plan are
entitled to have shares of AAON stock in their accounts sold to the Company to
provide diversification of their investments. Through September 30, 2006, the
Company repurchased 226,855 shares for an aggregate price of $4.7 million. The
cash used in financing activities in 2005 was related primarily to the
repurchase of stock. The Company's revolving credit facility provides for
maximum borrowings of $15.2 million. Interest on borrowings is payable monthly
at the Wall Street Journal prime rate less .5% or LIBOR plus 1.6%, at the
election of the Company (6.93% at September 30, 2006). The Company's borrowings
under the revolving credit facility were $6.5 million and $445,000 at September
30, 2006, and September 30, 2005, respectively. In addition, the Company has a
$600,000 letter of credit that expires December 31, 2006. Borrowings available
under the revolving credit facility at September 30, 2006, were $8.1 million.
The credit facility previously required the Company to maintain a certain
financial ratio and prohibited the declaration of cash dividends. In conjunction
with the Board's vote on February 14, 2006, the restriction of payments of
dividends was waived by the lender and removed from the covenants with the
renewal of the line of credit July 30, 2006. At September 30, 2006, the Company
was in compliance with its financial ratio covenants. On July 30, 2006, the
Company renewed the line of credit with a maturity date of July 30, 2007.

Management believes the Company's bank revolving credit facility (or comparable
financing), and projected cash flows from operations will provide the necessary
liquidity and capital resources to the Company for a minimum of the next twelve
months. The Company's belief that it will have the necessary liquidity and
capital resources is based upon its knowledge of the HVAC industry and its place
in that industry, its ability to limit the growth of its business if necessary,
and its relationship with its existing bank lender. For information concerning
the Company's revolving credit facility at September 30, 2006, see Note 6 to the
financial statements included in this report.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Because these estimates and assumptions require significant
judgment, future actual results could differ from those estimates and could have
a significant impact on the Company's results of operations, financial position
and cash flows. The Company reevaluates its estimates and assumptions on a
monthly basis. A discussion of the significant accounting policies we have
adopted and followed in the preparation of our consolidated financial statements
is included within our Annual Report on Form 10-K for the year ended December
31, 2005, and there have been no material changes to these policies through
September 30, 2006.

New Accounting Pronouncements

FASB (Financial Accounting Standards Board) Statement 123(R), Accounting for
Stock-Based Compensation replaces FASB Statement No. 123, Accounting for
Stock-Based Compensation, and supersedes APB Opinion No. 25, Accounting for
Stock Issued to Employees. The Statement requires measurement of the cost of
employee services received in exchange for an award of equity instruments based
on the grant-date fair value of the award. The compensation cost will be
recognized over the period of time during which an employee is required to
provide service in exchange for the award, which will be the vesting period. The
Statement applies to all awards granted and any unvested awards at December 31,
2005. Effective January 1, 2006, the Company adopted the fair value recognition
method of Statement of Financial Accounting Standards No. 123(R) Share-Based
Payments (SFAS 123R), using the modified-prospective-transition method.

FASB Statement 151, Inventory Costs, replaces Accounting Research Bulletin No.
43, Chapter 4, Inventory Pricing. The Statement requires that abnormal amounts
of idle facility expense, freight, handling costs and spoilage should be
expensed as incurred and not included in overhead as an inventory cost. The new
statement also requires that allocation of fixed production overhead costs
should be based on normal capacity of the production facilities. The Statement
was effective January 1, 2006. The adoption of this statement did not have a
material impact on the Company's Consolidated Financial Statements.

In July 2006, the FASB released FASB Interpretation No. 48, Accounting for
Uncertainty in Income Taxes, an Interpretation of FASB Statement 109. FIN 48
clarifies the accounting for uncertain tax positions as described in SFAS No.
109, Accounting for Income Taxes, and requires a company to recognize, in its
financial statements, the impact of a tax position only if that position is
"more likely than not" of being sustained on an audit basis solely on the
technical merits of the position. FIN 48 also requires qualitative and
quantitative disclosures including a discussion of reasonably possible changes
that might occur in the recognized tax benefits over the next twelve months as
well as a roll-forward of all unrecognized tax benefits. FIN 48 is effective for
fiscal years beginning after December 15, 2006. The Company is currently
evaluating the effect FIN 48 will have on the Company's Consolidated Financial
Statements.

In September 2006, the FASB released SFAS No. 157, "Fair Value Measurements".
Statement 157 defines fair value and establishes a framework for measuring fair
value in generally accepted accounting principles, and expands disclosures about
fair value measurements. Although SFAS 157 applies to (and amends) the
provisions of existing authoritative literature, it does not, of itself, require
any new fair value measurements or establish valuation standards. SFAS 157 is
effective for financial statements issued for fiscal years beginning after
November 15, 2007, and interim periods within those fiscal years. Adoption of
SFAS 157 is not expected to have a material impact on the Company's Consolidated
Financial Statements.

In September 2006, the staff of the Securities and Exchange Commission issued
Staff Accounting Bulletin No. 108 (SAB 108), which provides interpretive
guidance on how the effects of the carryover or reversal of prior year
misstatements should be considered in quantifying a current year misstatement.
SAB 108 becomes effective in fiscal 2007. Adoption of SAB 108 is not expected to
have a material impact on the Company's Consolidated Financial Statements.

Forward-Looking Statements

This Quarterly Report includes "forward-looking statements" within the meaning
of the Private Securities Litigation Reform Act of 1995. Words such as
"expects", "anticipates", "intends", "plans", "believes", "seeks", "estimates",
"will", and variations of such words and similar expressions are intended to
identify such forward-looking statements. These statements are not guarantees of
future performance and involve certain risks, uncertainties and assumptions,
which are difficult to predict. Therefore, actual outcomes and results may
differ materially from what is expressed or forecasted in such forward-looking
statements. Readers are cautioned not to place undue reliance on these
forward-looking statements, which speak only as of the date on which they are
made. The Company undertakes no obligations to update publicly any
forward-looking statements, whether as a result of new information, future
events or otherwise. Important factors that could cause results to differ
materially from those in the forward-looking statements include (1) the timing
and extent of changes in raw material and component prices, (2) the effects of
fluctuations in the commercial/industrial new construction market, (3) the
timing and extent of changes in interest rates, as well as other competitive
factors during the year, and (4) general economic, market or business
conditions.


Item 3.  Quantitative and Qualitative Disclosures About Market Risk.

The Company is subject to interest rate risk on its revolving credit facility
which bears variable interest based upon a prime or LIBOR rate. The Company had
an outstanding balance of $6.5 million as of September 30, 2006.

Foreign sales accounted for less than 5% of the Company's sales in 2006 and the
Company accepts payment for such sales in U.S. and Canadian dollars; therefore,
the Company believes it is not exposed to significant foreign currency exchange
rate risk on these sales. Foreign currency transactions and financial statements
are translated in accordance with Statement of Financial Standards No. 52,
Foreign Currency Translation. The Company uses the U.S. dollar as its functional
currency, except for the Company's Canadian subsidiaries, which use the Canadian
dollar. Adjustments arising from translation of the Canadian subsidiaries'
financial statements are reflected in Consolidated Statements of Stockholders'
Equity. Transaction gains or losses that arise from exchange rate fluctuations
applicable to transactions are denominated in Canadian currency and are included
in the results of operations as incurred.

Important raw materials purchased by the Company are steel, copper and aluminum,
which are subject to price fluctuations. The Company attempts to limit the
impact of price increases on these materials by entering cancelable fixed price
contracts with its major suppliers for periods of 6 -12 months.

The Company does not utilize derivative financial instruments to hedge its
interest rate or raw materials price risks.

Item 4.  Controls and Procedures.

(a)      Evaluation of Disclosure Controls and Procedures


At the end of the period covered by this Quarterly Report on Form 10-Q, the
Company's management, under the supervision and with the participation of the
Company's Chief Executive Officer and Chief Financial Officer, has evaluated the
effectiveness of the design and operation of the Company's disclosure controls
and procedures. Based on that evaluation, the Company's Chief Executive Officer
and Chief Financial Officer believe that:

     o   The Company's disclosure controls and procedures are designed to
         ensure that information required to be disclosed by the Company in the
         reports it files under the Securities Exchange Act of 1934 is
         recorded, processed, summarized and reported within the time periods
         specified in the SEC's rules and forms; and

     o   The Company's disclosure controls and procedures operate such that
         important information flows to appropriate collection and disclosure
         points in a timely manner and are effective to ensure that such
         information is accumulated and communicated to the Company's
         management, and made known to the Company's Chief Executive Officer
         and Chief Financial Officer, particularly during the period when this
         Quarterly Report was prepared, as appropriate to allow timely
         decisions regarding the required disclosure.

AAON's Chief Executive Officer and Chief Financial Officer have evaluated the
Company's disclosure controls and procedures and concluded that these controls
and procedures were effective as of September 30, 2006.

(b)      Changes in Internal Control over Financial Reporting

There have been no changes in internal control over financial reporting that
occurred during the quarter that have materially affected, or are reasonably
likely to materially affect, the Company's internal control over financial
reporting.

                           PART II - OTHER INFORMATION


Item 1A. Risk Factors.

There have been no material changes from risk factors as previously disclosed in
registrant's Form 10-K in response to Item 1A, to Part I of Form 10-K.


Item 2.  Unregistered Sales of Equity and Securities and Use of Proceeds.

Following repurchases of approximately 12% of its outstanding Common Stock
between September 1999 and September 2001, the Company announced and began its
current stock repurchase program on October 17, 2002, targeting repurchases of
up to an additional 10% (1,325,000 shares) of its outstanding stock. Through
September 30, 2006, the Company had repurchased a total of 1,257,864 shares
under the current program for an aggregate price of $22,034,568, or an average
of $17.52 per share. On February 14, 2006, the Board of Directors approved the
suspension of the Company's repurchase program.

On July 1, 2005, the Company entered into a stock repurchase arrangement by
which employee-participants in AAON's 401K Savings and Investment Plan are
entitled to have shares of AAON stock in their accounts sold to the Company to
provide diversification of their investments. Through September 30, 2006, the
Company repurchased 226,855 shares for an aggregate price of $4,698,783 or an
average price of $20.71 per share.


Item 5.  Other Information.

On February 14, 2006, the Board of Directors voted to initiate a semi-annual
cash dividend of $0.20 per share to the holders of the outstanding Common Stock
of the Company as of the close of business on June 12, 2006, the record date,
payable on July 3, 2006.
