                          AAON, Inc., and Subsidiaries
                 Notes to the Consolidated Financial Statements
                                  June 30, 2007
                                   (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, 2006, filed by AAON, Inc. with the SEC. In the opinion
of management, the accompanying financial statements include all normal,
recurring adjustments required for a fair presentation of the results of the
periods presented. Operating results for the six months ended June 30, 2007, are
not necessarily indicative of the results that may be expected for the year
ending December 31, 2007.

Revenue Recognition

The Company recognizes revenues from sales of products at the time of shipment.
For sales initiated by independent manufacturer representatives, the Company
recognizes revenues net of the representatives' commission. The Company's policy
is to exclude sales taxes from revenue when collected and expenses when paid and
instead, record the collection and payment of sales taxes through a liability
account.

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
and Comprehensive Income. Transaction gains or losses that arise from exchange
rate fluctuations applicable to transactions are denominated in Canadian
currency and are included in `Other income' in the results of operations as
incurred.

New Accounting Pronouncements

In June 2006, the FASB issued FIN 48, Accounting for Uncertainty in Income
Taxes--an interpretation of FASB Statement No. 109, Accounting for Income Taxes.
This interpretation addresses the determination of whether tax benefits claimed
or expected to be claimed on a tax return should be recorded in the financial
statements. Under FIN 48, the Company may recognize the tax benefit from an
uncertain tax position only if it is more likely than not that the tax position
will be sustained on examination by the taxing authorities, based on the
technical merits of the position. The tax benefits recognized in the financial
statements from such a position should be measured based on the largest benefit
that has a greater than fifty percent likelihood of being realized upon ultimate
settlement. FIN 48 also provides guidance on derecognition, classification,
interest and penalties on income taxes, accounting in interim periods and
requires increased disclosures. The Company adopted the provisions of FIN 48 on
January 1, 2007. As a result of the implementation of FIN 48, the Company
recorded a $551,000 increase in the liability for unrecognized tax benefits,
which is offset by an increase of the deferred tax assets of $155,000, resulting
in a decrease to the January 1, 2007, retained earnings balance of $396,000 (for
additional information see Note 9 to the Consolidated Financial Statements).

                                      -5-


In June 2006, the Emerging Issues Task Force reached a consensus on Issue 06-3
("EITF 06-3"), How Sales Tax Collected from Customers and Remitted to
Governmental Authorities Should Be Presented in the Income Statement. The
guidance requires that a company disclose its accounting policy (i.e., gross or
net presentation) regarding presentation of taxes within the scope of EITF 06-3.
If taxes are reported on a gross basis, a company should disclose the amount of
such taxes for each period for which an income statement is presented. EITF 06-3
is effective for fiscal periods beginning after December 15, 2006. As disclosed
in the "Revenue Recognition" footnote above, the Company presents sales net of
sales taxes. Accordingly, this issue does not have a financial impact to the
Company.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements. SFAS
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. The Company will adopt SFAS 157
on January 1, 2008. Adoption of SFAS 157 is not expected to have a material
impact on the Company's Consolidated Financial Statements.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for
Financial Assets and Financial Liabilities, which creates an alternative
measurement treatment for certain financial assets and financial liabilities.
SFAS 159 permits fair value to be used for both the initial and subsequent
measurements on an instrument-by-instrument basis, with changes in the fair
value to be recognized in earnings as those changes occur. This election is
referred to as the fair value option. SFAS 159 also requires additional
disclosures to compensate for the lack of comparability that will arise from the
use of the fair value option. SFAS 159 is effective for fiscal years beginning
after November 15, 2007. The Company will adopt SFAS 159 on January 1, 2008.
Adoption of SFAS 159 is not expected to have a material impact on the Company's
Consolidated Financial Statements.


2.  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 unsuccessful.

Accounts receivable balances at June 30, 2007, and December 31, 2006, and the
changes in the allowance for doubtful accounts for the six months ended June 30,
2007, and 2006, are as follows:

3.  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. Inventory
balances at June 30, 2007, and December 31, 2006, and the changes in the
allowance for excess and obsolete inventories account for the six months ended
June 30, 2007, and 2006, are as follows:

                                      -7-


6.  REVOLVING CREDIT FACILITY

The Company's revolving credit facility provides for maximum borrowings of $15.2
million which is provided by the Bank of Oklahoma, National Association. Under
the line of credit, there is one standby letter of credit totaling approximately
$600,000. The letter of credit is a requirement of the Company's workers
compensation insurance and will expire December 31, 2007. Interest on borrowings
is payable monthly at the Wall Street Journal prime rate less 0.5% or LIBOR plus
1.6%, at the election of the Company (6.92% at June 30, 2007). No fees are
associated with the unused portion of the committed amount. At June 30, 2007,
and December 31, 2006, the Company had no borrowings outstanding under the
revolving credit facility. Borrowings available under the revolving credit
facility at June 30, 2007, were $14.6 million. The credit facility requires the
Company to maintain certain financial ratios. At June 30, 2007, the Company was
in compliance with its financial ratio covenants. On July 30, 2007 the Company
renewed the line of credit with a maturity date of July 30, 2008.


7.  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 year, commencing one year after the date of grant. 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. On May 22, 2007, the
stockholders of the Company adopted a Long-Term Incentive Plan which provides an
additional 500,000 shares that can be granted in the form of stock options,
stock appreciation rights, restricted stock awards, performance units and
performance awards. Since inception of the Plan, non-qualified stock options and
restricted stock awards have been granted with the same vesting schedule as the
previous plan.

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 2006 and the first six
months of 2007 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 month periods ended June 30, 2007, and 2006, the Company
recognized approximately $148,000 and $107,000 and for the six month periods
ended June 30, 2007, and 2006, the Company recognized approximately $311,000 and
$233,000, respectively, in pre-tax compensation expense in the Consolidated
Statements of Income related to the stock option plan. The total pre-tax
compensation cost related to nonvested stock options not yet recognized as of
June 30, 2007, is $2.1 million and is expected to be recognized over a
weighted-average period of 2.4 years. Statement 123(R) requires that cash flows
from the exercise of stock options resulting from tax benefits in excess of
recognized cumulative compensation cost (excess tax benefits) be classified as
financing cash flows. For the six months ended June 30, 2007, and 2006,
$1,814,000 and $1,270,000, respectively, of such excess tax benefits from
share-based payment plans was classified as financing cash flows.

The following assumptions were used to determine the fair value of the unvested
stock options on the original grant date for expense recognition purposes for
options granted during the six months ended June 30, 2007, and June 30, 2006. No
options were granted to directors or officers for the six months ended June 30,
2007.

The expected term of the options is based on evaluations of historical and
expected future employee exercise behavior. The risk-free interest rate is based
on the U.S. Treasury rates at the date of grant with maturity dates
approximately equal to the expected life at the grant date. Volatility is based
on historical volatility of the Company's stock. The Company initiated a
dividend payout in the second quarter of 2006. The Company used Board approved
semi-annual dividend payouts of $0.20 per share to calculate the expected
dividend yield.

The Company also grants restricted stock awards to employees and directors.
These awards are recorded at their fair values on the date of grant and
compensation cost is recorded using straight-line vesting over the service
period. The weighted average grant date fair value of restricted stock awards
granted during the six months ended June 30, 2007, was $29.76 per share (total
grant date fair value of $273,792). There were no restricted stock awards
granted during the six months ended June 30, 2006. As of June 30, 2007, there
was no aggregate intrinsic value of restricted stock awards that are expected to
vest. In addition, as of June 30, 2007, unrecognized compensation cost related
to non-vested restricted stock awards was $265,578 which is expected to be
recognized over a weighted average period of three years. The following summary
reflects restricted stock awards activity and related information.

9.  INCOME TAXES

The Company and its subsidiaries file income tax returns in the U.S. federal
jurisdiction, and various state and foreign jurisdictions. Effective January 1,
2007, the Company adopted FIN 48. In accordance with FIN 48, the Company
recorded a $551,000 increase in its liability for unrecognized tax benefits,
interest, and penalties, which is offset by an increase of the deferred tax
assets of $155,000, resulting in a decrease to the January 1, 2007, retained
earnings balance of $396,000. The total amount of unrecognized tax benefits that
if recognized would affect the effective tax rate is $396,000. The total amount
of unrecognized tax benefits at January 1, 2007, is $447,000 related to tax
positions for which it is reasonably possible that the total amounts could
significantly decrease during the next twelve months. This amount represents the
unrecognized tax benefits comprised of items related to determination of state
nexus. Resolution of these tax benefits will occur through a voluntary
compliance program, which was initiated during the three months ended June 30,
2007.

The Company recognizes accrued interest and penalties related to unrecognized
tax benefits in income tax expense. At January 1, 2007, the Company had accrued
$141,000 and $29,000 for the potential payment of interest and penalties,
respectively.

As of June 30, 2007, the Company is subject to U.S. Federal income tax
examinations for the tax years 2004 through 2006, and to non-U.S. income tax
examinations for the tax years of 2004 through 2006. In addition, the Company is
subject to state and local income tax examinations for the tax years 2001
through 2006.

There were no significant changes to any of these amounts during the six months
ended June 30, 2007.


10. STOCK REPURCHASE

Following repurchases of approximately 12% of its outstanding Common Stock
between September 1999 and September 2001, the Company announced and began its
most recent stock repurchase program on October 17, 2002, targeting repurchases
of up to an additional 10% (1,325,000 shares) of its outstanding stock. Through
June 30, 2006, the Company had repurchased a total of 1,257,864 shares under
this 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 June 30, 2007, the Company
repurchased 287,713 shares for an aggregate price of $6,321,000 or an average
price of $21.97 per share.

On November 7, 2006, the Board of Directors authorized the Company to repurchase
shares from certain directors following their exercise of stock options expiring
on March 11, 2007. To date, the Company repurchased 64,875 shares for an
aggregate price of $1,799,000 or an average price of $27.73.

11. 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.

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, coils and boilers.
The Company has successfully gained market share through its "semi-custom"
product lines, which offer the customer value, quality, function, serviceability
and efficiency. Custom units are marketed and sold to retail, manufacturing,
educational, medical and other commercial industries. AAON markets units to all
50 states in the United States and certain provinces in Canada. International
sales are less than five percent as the majority of all sales are domestic.

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. Raw materials ranged in prices and at times increases were
incurred up to approximately 24% for steel, 42% for aluminum and 400% for copper
from 2004 to June 30, 2007. The increases resulted in economic challenges to
AAON. AAON reviewed and adjusted current pricing strategies and created
efficiencies in production in order to mitigate the economic factors of
increasing commodity prices. The major component costs include compressors,
electric motors and electronic controls, which also increased due to increases
in commodities.

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. Warranty charges on heat exchangers do not occur frequently.

The office facilities of the Company 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.

Other operations 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). An additional 15
acres of land was purchased for future expansion in 2004 and 2005 in Longview,
Texas. 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

Key events impacting AAON's cash balance, financial condition, and results of
operations for the six months ended June 30, 2007 include the following:

     o    Increased sales due to innovative products and effective moderation of
          commodity costs with purchase agreements and pricing strategies
          affected sales and gross margin positively, which resulted in
          significantly higher revenues and income.
     o    In February 2006, the Board of Directors authorized a semi-annual cash
          dividend payment. Cash dividends were paid in January of 2007,
          affecting cash by $2.5 million. Dividends were declared in the second
          quarter of 2007 and accrued. Payment of cash dividends occurred in
          July of 2007 in the amount of $2.5 million.
     o    Stock repurchases of AAON stock from employee's 401(k) savings and
          investments plan were authorized in 2005. AAON continued to repurchase
          stock from employees and made repurchases from other incentive plans
          throughout the six months ended June 30, 2007, resulting in cash
          payments of $2.9 million. This cash outlay is partially offset by cash
          received from options exercised by employees as a part of an incentive
          bonus program. The cash received in the first six months of 2007 from
          options exercised was $1.0 million.
     o    Purchases of equipment to create efficiencies remained a priority.
          AAON capital expenditures were $7.2 million. Equipment purchases and
          proper upkeep of manufacturing facilities create significant
          efficiencies, lower production costs and allow continued growth in
          production. The Company currently estimates it will spend a total of
          approximately $10.0 million on capital expenditures in 2007 for
          continued growth.

                                      -13-


Net Sales

Net sales increased $11.7 million (19.8%) to $70.8 million from $59.1 million
for the three months ended June 30, 2007, and $16.7 million (14.8%) to $129.5
million from $112.8 million for the six months ended June 30, 2007, compared to
the same periods in 2006. Increased sales were attributable to an increase in
volume of product sold related to the Company's new and redesigned products
being favorably received by its customers and from certain pricing strategies
implemented in 2006 and the second quarter of 2007 that are now being fully
recognized as back orders from 2006 become completed. Management anticipates
continued growth throughout 2007.

Gross Profit

Gross profit increased $5.5 million (54.1%) to $15.6 million from $10.1 million
for the three months ended June 30, 2007, and increased $10.8 million (52.8%) to
$31.3 million from $20.5 million for the six months ended June 30, 2007,
compared to the same periods in 2006. Gross margins were 22.0% compared to 17.1%
for the three months ended June 30, 2007, and June 30, 2006, respectively, and
were 24.2% compared to 18.2% for the six months ended June 30, 2007, and June
30, 2006, respectively. The increase in gross profit results from pricing
strategies becoming fully utilized and production and labor efficiencies as
volume remains at a high and steady level. The Company also began to see a
leveling off of raw material increases, thus lowering the cost of raw materials
and allowing for higher gross profits.

Steel, copper and aluminum are high volume materials used in the manufacturing
of the Company's products, which are obtained from domestic suppliers. Raw
materials ranged in prices and at times increases were incurred up to
approximately 24% for steel, 42% for aluminum and 400% for copper from 2004 to
June 30, 2007, causing increased inventory costs. 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;
therefore, the Company is also experiencing price increases from component part
suppliers. The Company is beginning to see some leveling off of the increases in
certain materials, but continues to monitor these costs and price units
accordingly. The Company instituted several price increases to customers from
2004 to 2007 in an attempt to offset the continued increases in steel, copper
and aluminum. 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

Selling, general and administrative expenses increased $417 thousand (8.6%) to
$5.3 million from $4.9 million for the three months ended June 30, 2007, and
increased $1.6 million (17%) to $11.0 million from $9.4 million for the six
months ended June 30, 2007, compared to the same periods in 2006. The increase
in selling, general and administrative expenses was primarily caused by an
increase in profit sharing due to increased net income. The Company contributes
10% of pre-tax profit to all eligible employees equally on a quarterly basis to
reward employee productivity.

Other Income

Other income was $82,000 and $138,000 for the three months ended June 30, 2007,
and 2006, respectively. Other income was $270,000 and $264,000 for the six
months ended June 30, 2007, and 2006, respectively. Other income is attributable
primarily to rental income from the Company's expansion facility. All expenses
associated with the facility that are allocated to the rental portion of the
building are included in Other income. The Company plans to continue to monetize
the expansion facility until it is needed for increased capacity. Other income
also includes foreign currency gains and losses that result from operations in
Canada. The weakened U.S. dollar was the primary reason for the decrease in
Other income for the three months ended June 30, 2007.

Analysis of Liquidity and Capital Resources

AAON's working capital and capital expenditure requirements are generally met
through net cash provided by operations and the revolving bank line of credit.

Cash Flows Provided by Operating Activities. Net cash provided by operating
activities decreased in the six months ended June 30, 2007, by $1.6 million from
the prior years six months ended June, 30, 2006. The decrease is primarily the
result of increased inventory due to increased levels to accommodate future
sales. Increased accounts receivable also contributed to the decrease in
operating cash due to the timing of shipment of products. The increased
inventory and accounts receivable is partially offset by the increase in Net
income based on factors stated above as well as the increased accrued
liabilities, which consists of an increase in commission's payable.

                                      -14-


Cash Flows Used in Investing Activities. Cash flows used in investing activities
were $7.2 million and $12.3 million for the six months ended June 30, 2007, and
2006, respectively. The decrease in cash flows used in investing activities in
2007 was primarily related to lower capital expenditures of $7.2 million for
additions to manufacturing facilities, machinery and equipment compared to $12.3
million for the same period in 2006. Capital expenditures in 2007 related to
building renovations and machinery and equipment to further automate production.
Management utilizes cash flows provided from operating activities to fund
capital expenditures that are expected to spur growth and create efficiencies.
The Company is currently in line with budgeted capital expenditures of
approximately $10.0 million in 2007 for equipment requirements. The Company
expects its cash requirements to be provided from cash flows from operations.

For the six months ended June, 30, 2007, the Company did not invest nor receive
proceeds from any certificate of deposits. For the same period in 2006, the
Company received proceeds from investments of $2 million and reinvested a total
of $2 million.

Cash Flows Used in Financing Activities. Cash flows used in financing activities
were $2.6 million and $234,000 for the six months ended June 30, 2007, and 2006,
respectively. The increase of cash used in financing activities primarily
relates to cash dividends declared and paid and the continued repurchase of the
Company's stock.

The Company repurchased shares of stock from employees' 401(k) savings and
investment plan and other incentive plans for the six months ended June 30,
2007, in the amount of $2.9 million for 106,037 shares of stock. There were
shares of stock repurchased for a total of $2.2 million for the same period in
2006.

In February 2006, the Board of Directors authorized a semi-annual cash dividend
payment. Cash dividends were declared in December 2006 and were paid in January
2007 in the amount of $2.5 million. Cash dividends of $2.5 million were declared
and accrued for on June 11, 2007, and paid on July 2, 2007. Prior to 2006, no
cash dividends had been declared or paid. Board approval is required to
determine the date of declaration for each semi-annual payment.

The Company received cash from stock options exercised of $1.0 million and
classified the tax benefit of stock options exercised of $1.8 million in
financing activities for the six months ended June 30, 2007. Due to the increase
in stock price and the exercise price of options, the tax effect of the gains
received by the Company increased for the six months ended June 30, 2007. The
cash received for options exercised and income tax effect partially offset the
stock repurchase and dividend payments for the six months ended June 30, 2007.
The cash received from stock options exercised for the same period in 2006 was
$1.0 million and the tax benefit of stock options exercised was $1.3 million.


General

The Company's revolving credit facility provides for maximum borrowings of $15.2
million which is provided by the Bank of Oklahoma, National Association. Under
the line of credit, there is one standby letter of credit totaling approximately
$600,000. The letter of credit is a requirement of the Company's workers
compensation insurance and will expire December 31, 2007. Interest on borrowings
is payable monthly at the Wall Street Journal prime rate less 0.5% or LIBOR plus
1.6%, at the election of the Company (6.92% at June 30, 2007). No fees are
associated with the unused portion of the committed amount. At June 30, 2007 and
December 31, 2006, the Company had no borrowings outstanding under the revolving
credit facility. Borrowings available under the revolving credit facility at
June 30, 2007, were $14.6 million. The credit facility requires the Company to
maintain certain financial ratios. At June 30, 2007, the Company was in
compliance with its financial ratio covenants. On July 30, 2007, the line of
credit's maturity date was extended to July 30, 2008.

                                      -15-


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 fiscal year 2007 and the
foreseeable future. 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, its ability to authorize dividend cash payments, and its
relationship with its existing bank lender. For information concerning the
Company's revolving credit facility at June 30, 2007, 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.

Effective January 1, 2007, the Company adopted FIN 48, "Accounting for
Uncertainty in Income Taxes - an interpretation of FASB Statement No. 109." FIN
48 provides guidance for the recognition threshold and measurement attribute for
financial statement recognition and measurement of a tax position taken or
expected to be taken in a tax return. In accordance with FIN 48, the Company
recognized a cumulative-effect adjustment of $396,000, increasing its liability
for unrecognized tax benefits, interest and penalties and reducing the January
1, 2007 balance of retained earnings. See Note 9 for more information on income
taxes.

Except for the adoption of FIN 48 and EITF 06-3, there have been no significant
changes in critical accounting policies or management estimates since the year
ended December 31, 2006. A comprehensive discussion of the Company's critical
accounting policies and management estimates is included in Management's
Discussion and Analysis of Financial Condition and Results of Operations in the
Company's Annual Report on Form 10-K for the year ended December 31, 2006.

New Accounting Pronouncements

In June 2006, the FASB issued FIN 48, Accounting for Uncertainty in Income
Taxes--an interpretation of FASB Statement No. 109, Accounting for Income Taxes.
This interpretation addresses the determination of whether tax benefits claimed
or expected to be claimed on a tax return should be recorded in the financial
statements. Under FIN 48, the Company may recognize the tax benefit from an
uncertain tax position only if it is more likely than not that the tax position
will be sustained on examination by the taxing authorities, based on the
technical merits of the position. The tax benefits recognized in the financial
statements from such a position should be measured based on the largest benefit
that has a greater than fifty percent likelihood of being realized upon ultimate
settlement. FIN 48 also provides guidance on derecognition, classification,
interest and penalties on income taxes, accounting in interim periods and
requires increased disclosures. The Company adopted the provisions of FIN 48 on
January 1, 2007. As a result of the implementation of FIN 48, the Company
recorded a $551,000 increase in the liability for unrecognized tax benefits,
which is offset by an increase of the deferred tax assets of $155,000, resulting
in a decrease to the January 1, 2007, retained earnings balance of $396,000 (for
additional information see Note 8 to the Consolidated Financial Statements).

In June 2006, the EITF reached a consensus on Issue 06-3, How Sales Tax
Collected from Customers and Remitted to Governmental Authorities Should Be
Presented in the Income Statement. The guidance requires that a company disclose
its accounting policy (i.e., gross or net presentation) regarding presentation
of taxes within the scope of EITF 06-3. If taxes are reported on a gross basis,
a company should disclose the amount of such taxes for each period for which an
income statement is presented. EITF 06-3 is effective for fiscal periods
beginning after December 15, 2006. The Company presents sales net of sales
taxes. Accordingly, this issue will not have a financial impact to the Company.

In September 2006, the FASB released SFAS No. 157, Fair Value Measurements. SFAS
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. The Company will adopt SFAS 157
on January 1, 2008. Adoption of SFAS 157 is not expected to have a material
impact on the Company's Consolidated Financial Statements.

                                      -16-


In February, 2007, the FASB issued SFAS No. 159, The Fair Value Option for
Financial Assets and Financial Liabilities, which creates an alternative
measurement treatment for certain financial assets and financial liabilities.
SFAS 159 permits fair value to be used for both the initial and subsequent
measurements on an instrument by instrument basis, with changes in the fair
value to be recognized in earnings as those changes occur. This election is
referred to as the fair value option. SFAS 159 also requires additional
disclosures to compensate for the lack of comparability that will arise from the
use of the fair value option. SFAS 159 is effective for fiscal years beginning
after November 15, 2007. The Company will adopt SFAS 159 on January 1, 2008.
Adoption of SFAS 159 is not expected to have a material impact on the Company's
Consolidated Financial Statements.

Forward-Looking Statements

This Quarterly Report on Form 10-Q 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 obligation 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
no outstanding balance as of June 30, 2007.

Foreign sales accounted for less than 5% of the Company's sales for the six
months ended June 30, 2007, 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 accumulated other comprehensive income in the 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. The
exchange rate of the United States dollar to the Canadian dollar was $0.94 and
$0.90 at June 30, 2007, and June 30, 2006, respectively.

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, however; in 2006
cost increases in basic commodities, such as steel, copper and aluminum,
severely impacted profit margins. Continued volatility in prices may impact
profit margins in future periods.

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

                                      -17-


Item 4.  Controls and Procedures.

         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 June 30, 2007.

         Changes in Internal Control over Financial Reporting

There have been no changes in internal control over financial reporting that
occurred during 2007 that have materially affected, or are reasonably likely to
materially affect, the Company's internal control over financial reporting.

                                      -18-


                           PART II - OTHER INFORMATION


Item 1A.  Risk Factors.

There have been no material changes from risk factors as previously disclosed in
the Company's Form 10-K in response to Item 1A, to Part I of its 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 a
stock repurchase program on October 17, 2002, targeting repurchases of up to an
additional 10% (1,325,000 shares) of its outstanding stock. Through December 31,
