|1. | Basis of reporting for condensed consolidated financial statements and significant accounting policies.
|-- | -------------------------------------------------------------------------------------------------------

The accompanying unaudited condensed consolidated financial statements of CECO Environmental Corp. and subsidiaries (the Company,
we, us, or our) have been prepared in accordance with accounting principles generally accepted in the United States of America. In the opinion of management, the accompanying unaudited condensed consolidated
financial statements of the Company contain all adjustments (consisting only of normal recurring accruals) necessary to present fairly the financial position as of September 30, 2007 and December 31, 2006 and the results of operations for
the three-month and nine-month periods ended September 30, 2007 and 2006 and of cash flows for the nine-month periods ended September 30, 2007 and 2006. The results of operations for the three-month period and nine-month period ended
September 30, 2007 are not necessarily indicative of the results to be expected for the full year. The balance sheet as of December 31, 2006 has been derived from the audited consolidated financial statements included in the Companys
Annual Report on Form 10-K for the year ended December 31, 2006.

These financial statements and accompanying notes should be read in
conjunction with the audited financial statements and the notes thereto included in the Companys Annual Report on Form 10-K filed for the fiscal year ended December 31, 2006 with the Securities and Exchange Commission.

The Company adopted Financial Interpretation (FIN) 48 as of January 1, 2007, and has identified accounting for uncertain tax positions under this
guidance as a critical accounting policy. Considering tax laws of the multiple jurisdictions in which we operate, we assess whether it is more likely than not that a tax position will be sustained upon examination and through any litigation and
measure the largest amount of the benefit that is likely to be realized upon ultimate settlement. Consistent with our practice prior to adoption of FIN 48, we record related interest expense and penalties, if any, as a tax provision expense. Actual
results may differ substantially from our estimates.

Certain amounts in the September 30, 2006 financial statements have been
reclassified to conform to the September 30, 2007 presentation.



|2. | New Accounting Standards
|-- | ------------------------

FIN
48In June 2006, the Financial Accounting Standards Board (FASB) issued FIN 48, Accounting for Uncertainty in Income Taxesan interpretation of FASB Statement 109. FIN 48 clarifies the accounting for uncertainty in income taxes
recognized in an enterprises financial statements in accordance with FASB Statement No. 109, Accounting for Income Taxes. FIN 48 prescribes a comprehensive model for recognizing, measuring, presenting and disclosing in the financial
statements tax positions taken or expected to be taken on a tax return. FIN 48 became effective for the Company on January 1, 2007. The adoption of FIN 48 included recognition of a liability for unrecognized tax obligations of $653,000 which
was accounted for as an increase to the January 1, 2007 balance of accumulated deficit. The Company recognizes penalties and interest, if any, related to unrecognized tax obligations as a tax provision expense. Actual results may differ
substantially from our estimates. Additional details about the adoption of FIN 48 are provided in Note 11.

SFAS
157In September 2006 the FASB issued Statement of Financial Accounting Standard (SFAS) No. 157, Fair Value Measurements (SFAS No. 157). SFAS No. 157 clarifies the principle that fair value should
be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. Under the standard, fair value measurements would
be separately disclosed by level within the fair value hierarchy. SFAS 157 is effective for the Companys fiscal year beginning January 1, 2008, with early adoption permitted. The Company is in the process of evaluating SFAS No. 157.

SFAS 159In February 2007, the FASB issued SFAS No. 159, The Fair Value
Option for Financial Assets and Financial Liabilities. This Statement provides companies with an option to report selected financial assets and liabilities at fair value in an effort to reduce both complexity in accounting for financial
instruments and the volatility in earnings caused by measuring related assets and liabilities differently. SFAS No. 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between companies that choose
different measurement attributes for similar types of assets and liabilities. SFAS No. 159 requires entities to display the fair value of those assets and liabilities for which the entity has chosen to use fair value on the face of the balance
sheet. The standard, which will be effective for the Company as of January 1, 2008, is currently under evaluation by the Companys management. At this time, we do not expect to elect the fair value option for any eligible items and did not
early adopt the standard in the first quarter of 2007 as permitted.

|-- | ----------------------------

Our structure and
operational integration results in one segment that focuses on engineering, designing, building and installing systems that remove airborne contaminants from industrial facilities, as well as equipment that controls emissions from such facilities.
Accordingly, the condensed consolidated financial statements herein reflect the operating results of the segment.



|6. | Earnings Per Share
|-- | ------------------

For the three months ended
September 30, 2007 and 2006, basic weighted average common shares outstanding were 14,633,479 and 11,412,369, respectively, while diluted average common shares outstanding were 15,211,538 and 13,033,824, respectively. For the nine months ended
September 30, 2007 and 2006, basic weighted average common shares outstanding were 13,054,347 and 11,185,464, respectively while diluted average common shares outstanding were 13,634,829 and 12,778,806, respectively. We consider outstanding
options and warrants in computing diluted net income per share only when they are dilutive. Options to purchase 45,000 shares for the three months and nine months ended September 30, 2007 were not included in the computation of diluted earnings
per share due to their exercise price being greater than the market price of the stock.



|7. | Debt
|-- | ----

Total bank debt at September 30, 2007
was $0.8 million and $10.6 million at December 31, 2006. The bank debt at September 30, 2007 consists of $0.8 million due on the revolving line of credit. Unused credit availability under our $20.0 million revolving line of credit at
September 30, 2007 was $17.6 million. Availability is limited as determined by a borrowing base formula contained in the credit agreement.

We obtained a new credit facility (the Bank Facility) on December 29, 2005. The credit agreement was entered into by CECO Environmental Corp., its subsidiaries and Fifth Third Bank, an Ohio banking corporation (Fifth
Third Bank). On June 8, 2006 we amended the Bank Facility pursuant to a First Amendment to Credit Agreement (Amendment). H.M. White, Inc., a wholly owned subsidiary of CECO Group, Inc., was added as a borrower. The Amendment
amended the Bank Facility by, among other things 1) extending the maturity date of the Credit Agreement from January 31, 2007 to January 31, 2009, 2) lowering the interest rate on the revolving loan and term loan from the prime rate plus
2.25% and the prime rate plus 2.0%, respectively, to either prime plus 0.5% or LIBOR plus 2.75%, at our option, and 3) establishing an incentive pricing grid pegged to performance.

We further amended the Bank Facility pursuant to a Second Amendment to the Credit Agreement (Second Amendment) dated February 28, 2007.
Effox, Inc., a wholly owned subsidiary of CECO Group, Inc., (Effox) was added as a borrower. The Second Amendment amended the Bank Facility by, among other things 1) extending the maturity date of the Credit Agreement from
January 31, 2009 to January 31, 2010, 2) increasing the maximum revolving loan commitment from $13.0 million to $20.0 million, and 3) adding a second term loan in the aggregate amount of $5.0 million. Fees for this amendment amounted to
$30,000 and are being amortized as deferred financing costs over the remaining life of the loan.

In May 2007, all the outstanding
subordinated debt of $5.7 million and all the outstanding term notes of $7.2 million were retired using the proceeds from a secondary offering as described in Note 8. The remaining $6.0 million was applied to the revolving credit line and accrued
interest.

|8. | Shareholders equity
|-- | --------------------

In May 2007, we
completed a secondary offering and sale of CECO common stock which consisted of 1.4 million shares of newly issued stock and 2.3 million shares sold by related party selling stockholders. The initial closing was on May 17, 2007 and
the overallotment closing was on May 29, 2007. The Company received $14.2 million from this offering for the newly issued shares and $4.7 million from the exercise of 1.7 million related party selling shareholder warrants for a total of
$18.9 million. The proceeds were used to pay off all the outstanding subordinated debt of $5.7 million and all of the outstanding term notes of $7.2 million with the remaining $6.0 million being applied to the revolving credit line and accrued
interest.



|9. | Employee Benefit Plans
|-- | ----------------------

We sponsor a
non-contributory defined benefit pension plan for certain union employees. The plan is funded in accordance with the funding requirements of the Employee Retirement Income Security Act of 1974.

We also sponsor a post-retirement health care plan for office employees retiring before January 1, 1990. The plan allows retirees who have attained
the age of 65 to elect the type of coverage desired.

Retirement and health care plan expense is based on valuations performed by plan
actuaries as of the beginning of each fiscal year. The components of the expense consisted of the following:

We previously disclosed in our financial statements for the year ended December 31, 2006 that
we expected to make $570,000 in contributions to the Pension Plan during the year ending December 31, 2007. As of September 30, 2007, $455,000 has been contributed to the Pension Plan. The remaining 2007 contribution of $115,000 was made
in October 2007.

The funded status for our post-retirement health care plan is calculated based on the accumulated post-retirement benefit
obligation and not the projected benefit obligation as may have been inferred from the table presented in Note 12 of our 2006 10-K.

For the year ended December 31, 2006, the Company incorrectly recorded its transition adjustment
related to the adoption of SFAS No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans  an Amendment of FASB Statements No. 87, 88, 106 and 132(R). The Company reported its
transition adjustment of $226,000 as a component of 2006 other comprehensive income (loss), rather than as a direct adjustment to the ending balance of accumulated other comprehensive loss.

The Company will correct this 2006 reporting error in future filings as follows:

|10. | Stock-Based Compensation
|--- | ------------------------

During the nine months
ended September 30, 2007, the Company issued approximately 140,000 restricted stock awards to management and non-employee directors under the Companys 2007 Equity Incentive Plan. Approximately 30,000 of these awards are performance-based,
with various vesting periods through March 31, 2010. The remaining awards do not contain any such performance conditions, and vest over various periods through July 2010. The weighted average grant date fair value of these restricted stock
awards is $11.81 per share and the future compensation expense to be recognized for these awards is approximately $1.4 million as of September 30, 2007.

The Company accounts for stock-based compensation in accordance with SFAS No. 123(R), Share-Based Payment. SFAS No. 123(R) requires the Company to recognize compensation expense for stock-based
awards, measured at the fair value of the awards at the grant date. The Company recognized expense of approximately $294,000 and $33,800 during the quarters ended September 30, 2007 and 2006, respectively and $437,000 and $63,000 for the nine
months ended September 30, 2007 and 2006, respectively.



|11. | Income Taxes
|--- | ------------

The Company files income tax returns
in the various federal, state and local jurisdictions. The Company is no longer subject to federal, state and local income tax examinations by tax authorities for years before 2004. The Company adopted the provisions of FASB Interpretation
No. 48, Accounting for Uncertainty in Income Taxes (FIN 48), on January 1, 2007. As a result of the implementation of FIN 48, the Company recognized a liability for unrecognized tax obligations of $653,000 which was accounted
for as an increase to the January 1, 2007 balance of accumulated deficit. The Company recognizes penalties and interest related to unrecognized tax obligations in income tax expense.

|12. | Acquisition
|--- | -----------

On February 28, 2007, the
Company, through its wholly owned subsidiary CECO Acquisition Corp., purchased substantially all of the assets of Effox, Inc. (Effox). The purchase price was approximately $12.2 million, consisting of net cash paid of approximately $6.9
million and liabilities assumed of approximately $5.3 million. Additionally, the former owners of Effox are entitled to earn-out payments of up to $1.0 million upon the attainment of specified gross profit amounts through December 31, 2009. The
following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of closing adjusted for the final determination of the net asset values (dollars in thousands):

The following unaudited pro forma information represents the Companys results of operations
as if the acquisition had occurred on the first day of each of the respective periods:

The pro forma results have been prepared for informational purposes only and include adjustments to
convert Effox from the completed contract method of accounting to the percentage of completion method of accounting for contracts for which costs can reasonably be estimated, to amortize an acquired intangible asset with finite life, to reflect
additional interest expense for debt incurred to finance the acquisition, and to adjust income tax expense based on the Companys effective income tax rate during the period presented. These pro forma results do not purport to be indicative of
the results of operations that would have occurred had the purchase been made as of the beginning of the periods presented or of the results of operations that may occur in the future.



|13. | Comprehensive Income
|--- | --------------------

Comprehensive income consists
of net income, changes in the minimum pension liability, and translation gains and losses for foreign operations. Comprehensive income totaled $4,483,000 and $1,896,000 for the nine month periods ended September 30, 2007 and 2006,
respectively.

Sales for the three months and nine months ended September 30, 2007 have increased significantly over the
same periods in 2006 due to continuing strong domestic economic conditions, a strong demand for pollution control systems and additional revenues from our most recent acquisition. Consolidated net sales for the third quarter were $65.3 million, an
increase of $27.6 million or 73.2% compared to the same quarter in 2006. Consolidated net sales for the first nine months of 2007 were $168.0 million, an increase of $74.1 million or 78.9% compared to the same period in 2006. Effox, our most recent
2007 acquisition, generated equipment sales of $8.4 million for the quarter and $19.3 million for the nine month period. The remainder of the increase in sales is due to robust organic contracting sales increases for the quarter and the first nine
months.

New orders booked were $35.7 million during the third quarter of 2007 and $165.2 million for the first nine months of 2007, as compared to $43.9
million during the third quarter of 2006 and $114.8 million in the first nine months of 2006. The decline in bookings for the quarter is not necessarily indicative of a reduction in demand for our products and services because types and sizes of
orders vary from quarter to quarter and the flow of orders is not consistent.

Third quarter 2007 gross profit increased $5.1 million or 83.6% to $11.2
million compared to a gross profit of $6.1 million during the same period in 2006. Gross profit for the quarter as a percent of sales increased by .8 percentage points to 17.1% from 16.3% due to changes in product mix driven primarily by higher
equipment sales including sales from Effox as previously mentioned. For the first nine months of 2007, gross profit increased $13.0 million or 81.8% to $ 28.9 million compared to $15.9 million for the same period in 2006. Gross profit as a
percent of sales increased by .3 percentage points to 17.2% from 16.9% in 2006. This increase was also due to the same changes in product mix as discussed for the three month period.

Selling and administrative expenses increased by $2.5 million or 59.5% to $6.7 million during the third quarter of
2007 from $4.2 million in the same period of 2006. The increase was due to additional selling and administrative expenses of $1.2 million from Effox, our latest acquisition, as well as increases in legal and professional fees of $.5 million
including costs of $.3 million relating to our approaching accelerated filer status as of fiscal year end 2007 and additional Securities and Exchange Commission compliance requirements. Incentive compensation accruals and sales commissions relating
to improved financial performance as well as increased selling and administrative wages of $.8 million also contributed to the increase. Selling and administrative expenses as a percent of sales decreased by .8 percentage points from 11.1% in the
2006 quarter to 10.3% in the 2007 quarter. Selling and administrative expenses increased by $6.6 million or 57.9% to $18.0 million during the first nine months of 2007 from $11.4 million in the same period of 2006. This nine month increase consisted
of Effox expenses of $2.7 million, wages, commissions and incentive pay adding $2.5 million and increased professional fees adding $1.0 million. Selling and administrative expenses as a percent of sales decreased by 1.4 percentage points from 12.1%
in the 2006 nine month period compared to 10.7% for the nine months ended September 30, 2007.

Depreciation and amortization increased slightly from
$.3 million to $.4 million during the third quarter of 2007 and in the first nine months from $.9 million in 2006 to $1.1 million in 2007.

Operating
income increased by approximately $2.4 million or 141.2% to $4.1 million in the third quarter of 2007 compared to operating income of $1.7 million during the same quarter of 2006. The impact of significantly increased revenues and slightly higher
margins due to changing product mix in the third quarter, accompanied by related increases in selling and administrative expenses, were the primary factors for the increase in operating income. Operating income for the first nine months of 2007
increased by $6.3 million or 175.0% to $ 9.9 million compared to operating income of $3.6 million during the same period of 2006. This increase was also due to the impact of significantly increased revenues and slightly higher margins due to
changing product mix in the nine month period, offset by related increases in selling and administrative expenses.

The Company had no other income in the
third quarter of 2007 compared to other income of $409,000 in the third quarter of 2006. $432,000 of this third quarter 2006 income was the result of the exercise of 100,600 warrants issued in December 2001 less $23,000 of expense created by an
increase in the Companys stock price which increased the carrying value of the remaining warrants issued in December 2001. The Company had $9,000 of other income for the nine months ended September 30, 2007 compared to other income of
$703,000 for the same period in 2006. $727,000 of this nine month 2006 income was the result of the exercise of 348,567 warrants issued in December 2001 less $64,000 of expense created by an increase in the Companys stock price which increased
the carrying value of the remaining unexercised warrants which were issued in December 2001.

Interest expense decreased by $.4 million to $.1 million from
$.5 million during the third quarter of 2006. This decrease was due to lower outstanding loan balances on the Companys credit facility resulting from the use of funds raised in our recent secondary offering to retire debt.

Interest expense increased by $.2 million to $1.8 million from $1.6 million during the first nine months of 2007. This increase was partially due to a non-cash charge of
$.7 million to expense the remaining discount on the subordinated notes that were retired using the proceeds from our secondary stock offering in May 2007, offset by reduced interest charges of $.5 million due to lower outstanding balances on the
Companys credit facility.

Federal and state income tax provision was $1.7 million during the third quarter of 2007 compared to $.5 million
during the third quarter of 2006. Federal and state income tax expense was $3.5 million for the first nine months of 2007 compared to a tax expense of $.9 million in 2006.

The federal and state income tax expense for the three months and nine months ended September 30, 2007 was 44% of income from operations before income taxes. Our effective income tax rate is affected by certain
permanent timing differences including non-deductible interest expense and non-deductible compensation expense from the issuance of options and restricted stock. The federal and state income tax expense for the three months ended September 30,
2006 was 34% of income from operations before income taxes. This quarterly expense reflected an adjustment to increase the estimated effective tax rate from 27% to 31% for 2006, due to a higher estimated taxable income. Our effective
income tax rate was affected by certain permanent differences including non-deductible interest expense and non-taxable income from the exercise of warrants.

Net income for the quarter ended September 30, 2007 was $2.2 million compared with net income of $1.1 million for the same period in 2006. Net income for the nine months ended September 30, 2007 was $4.5 million compared with a
net income of $1.9 million for the same period in 2006. This increase in net income for the quarter and for the nine months ended September 30, 2007 was the result of the previously discussed factors.

Backlog

Our backlog consists of orders we have received for products
and services we expect to ship and deliver within the next 12 months. There can be no assurances that backlog will be replicated, increased or translated into higher revenues in the future.

Our backlog, as of September 30, 2007 was $94.4 million compared to $97.1 million as of December 31, 2006. The success of our business depends on a multitude
of factors related to our backlog and the orders secured during the subsequent period(s). Certain contracts are highly dependent on the work of contractors and other subcontractors participating in a project, over which we have no or limited
control, and their performance on such project could have an adverse effect on the profitability of our contracts. Delays resulting from these contractors and subcontractors, changes in the scope of the project, weather, and labor availability also
can have an effect on a contracts profitability.

Financial Condition, Liquidity and Capital Resources

Our principal sources of liquidity are cash flows from operations, available borrowings under our revolving credit facility and secondary equity offerings. Our principal
uses of cash are operating costs, debt service, payment of interest on our outstanding senior debt, capital expenditures, working capital and other general corporate requirements.

At September 30, 2007 and December 31, 2006, cash and cash equivalents totaled $ 732,000 and $445,000 respectively. Generally, we do not carry significant cash and cash equivalent balances because excess
amounts are used to pay down our revolving credit facility.

Total bank debt as of September 30, 2007 was $0.8 million and $10.6 million at
December 31, 2006. Unused credit availability under our $20.0 million revolving line of credit at September 30, 2007 was $17.6 million.

We obtained a new credit facility (the Bank Facility) on December 29, 2005. The credit agreement was
entered into by CECO Environmental Corp., its subsidiaries and Fifth Third Bank, an Ohio banking corporation (Fifth Third Bank). On June 8, 2006 we amended the Bank Facility pursuant to a First Amendment to Credit Agreement
(Amendment). H.M. White, Inc., a wholly owned subsidiary of CECO Group, Inc., was added as a borrower. The Amendment amended the Bank Facility by, among other things 1) extending the maturity date of the Credit Agreement from
January 31, 2007 to January 31, 2009, 2) lowering the interest rate on the revolving loan and term loan from the prime rate plus 2.25% and the prime rate plus 2.0%, respectively, to either prime plus 0.5% or LIBOR plus 2.75%, at our
option, and 3) establishing an incentive pricing grid pegged to performance.

We further amended the Bank Facility pursuant to a Second Amendment to the
Credit Agreement (Second Amendment) dated February 28, 2007. Effox, Inc., a wholly owned subsidiary of CECO Group, Inc., (Effox) was added as a borrower. The Second Amendment amended the Bank Facility by, among other
things 1) extending the maturity date of the Credit Agreement from January 31, 2009 to January 31, 2010, 2) increasing the maximum revolving loan commitment from $13.0 million to $20.0 million, and 3) adding a second term loan in the
aggregate amount of $5.0 million. Fees for this amendment amounted to $ 30,000 and are being amortized as deferred financing costs over the remaining life of the loan.

In May 2007, we completed a secondary offering and sale of CECO common stock which consisted of 1.4 million shares of newly issued stock and 2.3 million shares sold by related party selling stockholders. The
initial closing was on May 17, 2007 and the overallotment closing was on May 29, 2007. The Company received $14.2 million from this offering for the newly issued shares and $4.7 million from the exercise of 1.7 million related party
selling shareholder warrants for a total of $18.9 million. The proceeds were used to pay off all the outstanding subordinated debt of $5.7 million and all of the outstanding term notes of $7.2 million with the remaining $6.0 million being applied to
the revolving credit line and accrued interest.

On July 2, 2007, the agreement between Millworks Town Center (Purchaser), LLC and Kirk and Blum, an
indirect wholly owned subsidiary of the Company, for the sale of the Cincinnati manufacturing and corporate office facilities expired.

Effective
October 30, 2007, Kirk & Blum Manufacturing Company, an indirectly owned subsidiary of the Company, entered into an agreement with International Paper Company with respect to the purchase of an office and manufacturing facility located
in Springdale, Ohio. The completion of the transaction is subject to a number of closing conditions, including the sale of the Companys Cincinnati facility.

Cash provided by operating activities was $5.0 million in 2007 compared to cash used in 2006 of $3.3 million. Cash
provided by operating activities for the first nine months of 2007 was the result of net income of $4.5 million plus non-cash charges for depreciation and amortization of $1.1 million and non-cash interest expense of $.9 million, an increase in
accounts payable of $10.9 million and an increase in accrued income taxes of $.7 million offset by increases in accounts receivable of $6.9 million, an increase in costs and estimated earnings in excess of billings of $ 2.3 million, a decrease
in billings in excess of cost and estimated earnings of $4.0 million and an increase in inventory of $0.8 million. Other changes in working capital items provided cash of $0.8 million . Our net investment in working capital (excluding cash and cash
equivalents and current portion of debt) at September 30, 2007 and December 31, 2006 was $17.1 million and $14.5 million, respectively.

Net cash
used in investing activities related to capital expenditures for property and equipment of $1.2 million compared with $.6 million for the same period in 2006 and new business acquisitions of $7.0 million for the first nine months of 2007 compared
with $0 for 2006. If sales continue to increase in 2007, we anticipate increased capital spending. Additionally, capital expenditures may be incurred depending on the ultimate disposition of our Cincinnati property.

Financing activities provided cash of $3.4 million during the first nine months of 2007 compared with cash provided of $3.9 million during the same period of 2006.
Approximately $14.1 million was provided by a secondary stock offering and an additional $4.7 million was provided by warrant proceeds received from selling stockholders. These proceeds were used to retire subordinated debt of $5.7 million and to
reduce borrowings on our credit facility.

and possibility of further losses; fluctuations in operating results from period to period due to seasonality of our business; the effect of growth on our
infrastructure, resources, and existing sales; our ability to expand our operations in both new and existing markets; the potential for contract delay or cancellation; the potential for fluctuations in prices for manufactured components and raw
materials; our ability to raise capital and the availability of capital resources; our ability to fully utilize and retain executives; the impact of federal, state, or local government regulations; labor shortages or increases in labor costs;
economic and political conditions generally; and the effect of competition in the air pollution control and industrial ventilation industry.

We caution
investors that other factors might, in the future, prove to be important in affecting our results of operations. New factors emerge from time to time and it is not possible for management to predict all such factors, nor can it assess the impact of
each such factor on the business or the extent to which any factor, or a combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Investors are further cautioned not to place undue

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK



---

Risk Management Activities

In the normal course of business, we are exposed to market risk including changes in interest and raw material commodity prices. We may use derivative
instruments to manage our interest rate exposures. We do not use derivative instruments for speculative or trading purposes. Generally, we enter into hedging relationships such that changes in the fair values of cash flows of items and transactions
being hedged are expected to be offset by corresponding changes in the values of the derivatives.

Interest Rate Management

We may use interest rate swap contracts to adjust the proportion of our total debt that is subject to variable interest rates.

The remaining amount of loans outstanding under the Bank Facility bear interest at the floating rates as described in Note 9 to the consolidated financial statements
contained in the Companys Annual Report on Form 10-K for the year ended December 31, 2006 filed with the Securities and Exchange Commission.

Raw Materials

The profitability of our manufactured products is affected by changing purchase prices of steel and other materials. If
higher steel or other material prices cannot be passed on to our customers, operating income will be adversely affected.

Evaluation of Disclosure Controls and
Procedures

The Companys management, with the participation of the Companys Chief Executive Officer and Chief Financial Officer, has
evaluated the effectiveness of the Companys disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)), as of
September 30, 2007. 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 or submits under the Exchange Act is recorded, processed,
summarized and reported within the time periods specified by the SECs rules and forms and that such information is accumulated and communicated to the Companys management, including the Chief Executive Officer and Chief Financial
Officer, as appropriate, to allow timely decisions regarding required disclosure. Based on the evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective.

Changes in Internal Control Over Financial Reporting

During the
third quarter of fiscal 2007, there were no changes in the Companys internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Companys internal control over financial
reporting.
