|3. | Note Payable to Financial Institution and Long Term Debt
|-- | --------------------------------------------------------

On
May 31, 2007, the Company entered into an Amended and Restated Credit Agreement (Amended Credit Agreement). The Amended Credit Agreement amends and restates the Credit Agreement dated May 20, 2005, and provides for a revolving
loan, swing line loan and letters of credit in the aggregate amount of up to $90 million, with an option for the Company to increase that amount to $110 million upon lender approval. Borrowings under the Amended Credit Agreement are secured by
substantially all of the Companys accounts receivable, inventory and certain equipment. The Amended Credit Agreement expires on May 31, 2012. The balance outstanding under the credit agreement bears interest at rates related to LIBOR plus
0.75% to 1.625%, or the lending institutions prime rate, minus 0.5% to 0.0%. At September 30, 2007, we had $58.3 million outstanding under the credit facility bearing interest at a weighted average rate of 6.64%.

On May 31, 2007, the Company entered into an Amended and Restated Note Purchase and Private Shelf Agreement, which reflects favorable changes in certain financial
covenants and other changes to generally conform to the Amended Credit Agreement. The Company may issue additional notes under the Amended and Restated Note Purchase and Private Shelf Agreement in the aggregate principal amount of up to $35 million.



|4. | Contingencies
|-- | -------------

In November 1999, the Oregon Department of
Environmental Quality (ODEQ) requested performance of a preliminary assessment of the Companys plant located at 12005 N. Burgard in Portland, Oregon. The purpose of the assessment is to determine whether the plant has contributed
to sediment contamination in the Willamette River. The Company entered into a Voluntary Letter Agreement with ODEQ in mid-August 2000, and began working on the assessment. On December 1, 2000, a section of the lower Willamette River known as
the Portland Harbor was included on the National Priorities List (NPL) at

the request of the U.S. Environmental Protection Agency (EPA). EPA has not fully defined the stretch of the river that will make up the site.
However, the full and final site will include all suitable areas in proximity to the contamination necessary for the implementation of the response action including upland portions of the Site that contain sources of contamination to the
sediments in the river. The Companys plant is not located on the Willamette River; it lies in what may be the uplands portion of the Portland Harbor Site. EPA and ODEQ have agreed to share responsibility for leading the investigation and
cleanup of the Portland Harbor Site. ODEQ has the lead responsibility for conducting the upland work. The actual work in both the river and uplands is being performed by various owners or operators of land and facilities within the Site.

EPA and ODEQ have notified the Company and 68 other parties of potential liability under the Comprehensive Environmental Response, Compensation and Liability Act
(CERCLA) and the Resource Conservation and Recovery Act (RCRA) with respect to the Portland Harbor Site. EPA and ODEQ have urged the Company and other parties receiving the letters to voluntarily enter into negotiations to
participate in a remedial investigation and feasibility study (RI/FS) at the Portland Harbor Site. That RI/FS is currently being conducted by a group of potentially responsible parties known as the Lower Willamette Group
(LWG). The Company, along with other parties, reached an Interim Remedial Investigation / Feasibility Study settlement in February, 2007. This agreement required the Company to make a payment of $175,000 in June 2007 to the LWG.
This is an interim settlement only and does not obligate the Company to any further payment or liabilities. Therefore, the extent of the Companys participation in this work is not known, and no further adjustments to the Companys
financial statements have been recorded for this matter.

In 2001, groundwater containing elevated volatile organic compounds (VOCs) was identified in one
localized area of the Companys property furthest from the river. Assessment work in 2002 and 2003 to further characterize the groundwater is consistent with the initial conclusion that a source of the VOCs is located off site. There is no
evidence at this time showing a connection between detected VOCs in groundwater and Willamette River sediments.

ODEQ recommended a remedial investigation
and feasibility study for further evaluation of both groundwater and stormwater at the plant. On January 25, 2005, ODEQ and the Company entered into a Voluntary Agreement for Remedial Investigation and Source Control Measures. The Company
completed the additional assessment work required by the Agreement and submitted a Remedial Investigation/Source Control Evaluation Report to ODEQ on December 30, 2005. The conclusions of the report indicate that VOCs in groundwater do not
present an unacceptable risk to human or ecological receptors in the Willamette River, stormwater is appropriately managed under the Companys NPDES permit and the risk assessment screening results justify a No Further Action determination for
the facility. The ODEQ review of this report is ongoing.

The Company operates under numerous governmental permits and licenses relating to air emissions,
stormwater run-off, and other matters. The Company is not aware of any current material violations or citations relating to any of these permits or licenses. It has a policy of reducing consumption of hazardous materials in its operations by
substituting non-hazardous materials when possible. The Companys operations are also governed by many other laws and regulations, including those relating to workplace safety and worker health, principally the Occupational Safety and Health
Act and regulations thereunder which, among other requirements, establish noise and dust standards. The Company believes that it is in material compliance with these laws and regulations and does not believe that future compliance with such laws and
regulations will have a material adverse effect on the Companys business, financial condition and results of operations.

From time to time, the
Company is involved in litigation relating to claims arising out of its operations in the normal course of its business. The Company maintains insurance coverage against potential claims in amounts that it believes to be adequate. Management
believes that it is not presently a party to any other litigation, the outcome of which would have a material adverse effect on the Companys business, financial condition and results of operations.

|6. | Share-based Compensation
|-- | ------------------------

The Company has two stock option plans
for employees and directors. The 2007 Stock Incentive Plan, which was approved by shareholders at the Annual Meeting on May 30, 2007, provides for awards of stock options to purchase shares of common stock, stock appreciation rights, restricted
and unrestricted shares of common stock and restricted stock units. The 1995 Stock Option Plan for Nonemployee Directors provides for the grant of nonqualified options at an exercise price which is not less than 100 percent of the fair value on the
grant date. In addition, the Company has one inactive stock option plan, the Amended 1995 Stock Incentive Plan, under which previously granted options remain outstanding. There were 1,074,001 shares of common stock reserved for issuance under the
Companys stock compensation plans at September 30, 2007, against which 480,001 options have been granted and remain outstanding. The plans provide that options become exercisable according to vesting schedules, which range from immediate
for nonemployee directors to ratably over a 60-month period for all other options. Options terminate 10 years from the date of grant.

Effective
January 1, 2006, the Company adopted the provisions of Statement of Financial Accounting Standard (SFAS) No. 123(R), Share Based Payment (SFAS 123(R)), using a modified version of prospective
application. Under this transition method, compensation cost is recognized after the effective date as the requisite service is rendered for (i) the portion of outstanding options for which the requisite service had not yet been rendered at
December 31, 2005, based on the grant-date fair value of those options calculated under SFAS No. 123, Accounting for Stock-Based Compensation for pro forma disclosures and (ii) all share-based payments granted subsequent
to the effective date, based on the grant date fair value estimated in accordance with the provisions of SFAS 123(R). Under the modified version of prospective application, prior period financial statements have not been restated.

For the three and nine months ended September 30, 2007, total share-based compensation expense of $0 and $297,000, respectively, was included in selling, general
and administrative expense and deducted in arriving at income before provision for income taxes, and net income was reduced by $0 and $187,000, respectively. For the three and nine month periods ended September 30, 2006, total share-based
compensation expense of $25,000 and $225,000, respectively, was included in selling, general and administrative expense and deducted in arriving at income before provision for income taxes, and net income was reduced by $16,000 and $140,000,
respectively. As of September 30, 2007, all outstanding options are fully vested and there is no unrecognized compensation expense.

The total intrinsic value, defined as the difference between the current market value and the grant price, of
options exercised during the nine months ended September 30, 2007 was $1,763,000.

The fair value of each option granted under the Companys
stock option plans is estimated as of the date of grant using the Black-Scholes option-pricing model with the assumptions noted in the following table. The risk-free interest rate is based on the U.S. Treasury yield curve corresponding to the
expected life of the option in effect at the time of the grant. The expected life is based on the historical exercise pattern of similar groups of employees. Expected volatility is based on the historical volatility of the Companys stock.

The weighted average grant date fair value of options granted during 2007 and 2006 was $17.40 and $12.88,
respectively.



|7. | Income Taxes
|-- | ------------

The Company adopted the provisions of FASB
Interpretation No. 48 Accounting for Uncertainty in Income Taxesan interpretation of FASB Statement No. 109 (FIN 48) on January 1, 2007. As a result of the implementation of FIN 48, the Company recognized
no material adjustment in the liability for unrecognized income tax benefits. At the adoption date of January 1, 2007, we had $697,000 of unrecognized tax benefits, all of which would affect our effective tax rate if recognized. At
September 30, 2007, we have $799,000 of unrecognized tax benefits.

The Company files numerous income tax returns in the United States Federal
jurisdiction and in many state jurisdictions. With few exceptions, the Company is no longer subject to US Federal or state income tax examinations for years before 2003. The Company has been notified by the Internal Revenue Service that the 2005
federal tax filing will be audited. Although the completion of the audit is expected to occur within the next 12 months, the Company is unable to determine and quantify the expected FIN 48 reversal that may occur upon completion of the audit.

The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. As of September 30, 2007, the Company has
approximately $42,000 of accrued interest related to uncertain tax positions.



|8. | Earnings per Share
|-- | ------------------

Basic earnings per share is computed using the
weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed using the weighted average number of shares of common stock and dilutive common equivalent shares outstanding during the period.
Dilutive common equivalent shares outstanding include the dilutive effect of in-the-money options which are calculated based on the average share price for each period using the treasury stock method. Under the treasury stock method, the amount the
option holder must pay for exercising stock options, the amount of compensation cost that the Company has not yet recognized, and the amount of tax benefits that would be recorded in additional paid-in capital when the award becomes deductible are
assumed to be used to repurchase shares. Incremental

shares of 270,945 and 295,862 for the three months ended September 30, 2007 and 2006, respectively, and incremental shares of 280,012 and 285,208 for
the nine months ended September 30, 2007 and 2006, respectively, were used in the calculations of diluted earnings per share. For the three and nine months ended September 30, 2007, the calculation of diluted earnings per share included
all common equivalent shares. For the three months ended September 30, 2006, the calculation of diluted earnings per share included all common equivalent shares. For the nine months ended September 30, 2006, options to purchase 3,187
shares were excluded from the computation of diluted earnings per share because the exercise price of the options was greater than the average market price of the underlying common stock during these periods and thus the options would be
antidilutive.



|9. | Recent Accounting and Reporting Developments
|-- | --------------------------------------------

In February 2007 the
Financial Accounting Standards Board (FASB) issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (SFAS 159). SFAS 159 permits companies to choose to measure many financial
instruments and certain other items at fair value. SFAS 159 seeks to improve the overall quality of financial reporting by providing companies the opportunity to mitigate volatility in reported earnings caused by measuring related assets and
liabilities differently without having to apply complex hedge accounting provisions. SFAS 159 is effective for fiscal years beginning after November 15, 2007. The Company is assessing SFAS 159 and has not determined the impact that the adoption
of SFAS 159 will have on its financial position or results of operations.

In September 2006, the FASB issued SFAS No. 157, Fair Value
Measurements (SFAS 157). SFAS 157 defines fair value, establishes a framework for measuring fair value and requires enhanced disclosures about fair value measurements. SFAS 157 requires companies to disclose the fair value of its
financial instruments according to a fair value hierarchy (i.e., levels 1, 2, and 3, as defined). Additionally, companies are required to provide enhanced disclosure regarding instruments in the level 3 category, including a reconciliation of the
beginning and ending balances separately for each major category of assets and liabilities. 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 is assessing SFAS 157 and has not determined the impact that the adoption of SFAS 157 will have on its financial position or results of operations.

In June 2006, the FASB ratified the consensus reached by the Emerging Issues Task Force (EITF) related to EITF Issue No. 06-3, How Taxes Collected from Customers and Remitted to Governmental Authorities Should Be
Presented in the Income Statement (That Is, Gross versus Net Presentation) (EITF 06-3). EITF 06-3 concludes that the presentation of any tax assessed by a governmental authority that is both imposed on and concurrent with a
specific revenue-producing transaction between a seller and a customer, and may include, but is not limited to, sales, use, value added, and some excise taxes on either a gross basis (included in revenues and costs) or a net basis (excluded from
revenues) is an accounting policy that should be disclosed. In addition, for any such taxes that are reported on a gross basis, an entity should disclose the amounts of those taxes in interim and annual financial statements for each period for which
an income statement is presented if those amounts are significant. The provisions of EITF 06-3 should be applied to financial reports for interim and annual reporting periods beginning after December 15, 2006, with earlier adoption permitted.
The Company will continue to use the net basis for presentation.

In June 2006, the FASB ratified the consensus reached by the EITF related to EITF Issue
No. 06-5 Accounting for Purchases of Life InsuranceDetermining the Amount That Could Be Realized in Accordance with FASB Technical Bulletin No. 85-4, Accounting for Purchases of Life Insurance (EITF 06-5),
which requires that a policyholder consider additional amounts included in the contractual terms of the policy in determining the amount that could be realized under the life insurance policy. EITF 06-5 provides additional guidance for determining
the amount to be realized, including the policy level for which the analysis should be performed, amounts excluded and measurement criteria. EITF 06-5 is effective for fiscal years beginning after December 15, 2006. The adoption of EITF
06-5 had no impact on the Companys financial position or results of operations.

Overview

We are a leading North American manufacturer of
large-diameter, high-pressure steel pipeline systems for use in water infrastructure applications, primarily related to drinking water systems. Our pipeline systems are also used for hydroelectric power systems, wastewater systems and other
applications. We also make products for industrial plant piping systems and certain structural applications. These pipeline systems are produced by our Water Transmission Group from six manufacturing facilities strategically located across the
United States in Portland, Oregon; Denver, Colorado; Adelanto, California; Parkersburg, West Virginia; Saginaw, Texas; and, as of July 2, 2007, Pleasant Grove, Utah. Our Water Transmission Group accounted for approximately 71% of net sales in
2006.

Our Tubular Products Group operates two manufacturing facilities in Atchison, Kansas, and Houston, Texas and produces a range of products used in
several different markets. We currently make energy pipe, fire protection sprinkler pipe, agricultural pipe, traffic signpost systems and standard pipe that is primarily sold to distributors and used in many different applications. Our Tubular
Products Group generated approximately 24% of our net sales in 2006.

Our Fabricated Products Group generated the remaining 5% of our net sales in 2006.
Our Fabricated Products Group primarily produces propane tanks for distribution in rural and suburban areas of the United States. These tanks range in size from 120 gallons to 1,000 gallons. All of these products are produced at our Monterrey,
Mexico facility. Recently, we began to focus this facility on producing specialty fabrications for our Water Transmission Group.

Our water infrastructure
products are sold generally to installation contractors, who include our products in their bids to municipal agencies or privately-owned water companies for specific projects. We believe our sales are substantially driven by spending on new water
infrastructure with a recent trend towards spending on water infrastructure replacement, repair and upgrade. Within the total pipeline, our products best fit the larger-diameter, higher-pressure applications. We believe, because of our reputation
for quality, our long relationships and our breadth of product offerings, our products are generally included in most projects for which the pipe falls within our manufacturing capabilities.

Our Tubular Products Groups sales volume is typically driven by non-residential construction spending, energy spending, highway spending and general economic
conditions. We focus on products for which we believe we have a sustainable advantage and have limited our reliance on certain products, such as fence frameworks and mechanical tubing, which are very susceptible to import competition. This strategy
resulted in an improvement in gross margin beginning in 2006. As we look ahead, we see opportunities to increase volume through growth in energy products, non-residential construction products and traffic signpost systems.

Overall demand for our Fabricated Products Groups propane tanks is primarily driven by weather patterns and residential heating needs, construction activity, and
general economic conditions. In the later part of 2006, we began manufacturing specialty pipe fittings for our Water Transmission Group. We believe this may be the best utilization of this facility in the long-term.

Critical Accounting Policies and Estimates

The discussion and
analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these
financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our
estimates, including those related to revenue recognition and allowance for doubtful accounts. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results
may differ from these estimates under different assumptions or conditions. A description of our critical accounting policies and related judgments and estimates that affect the preparation of our consolidated financial statements is set forth in our
Annual Report on Form 10-K for the year ended December 31, 2006.

Three Months and Nine Months Ended September 30, 2007 Compared to Three Months and Nine Months Ended
September 30, 2006

Net Sales.Net sales remained steady at $92.0 million for the third quarter of 2007 compared to $92.4 million for
the third quarter of 2006, and increased 14.3% to $284.6 million in the first nine months of 2007 from $249.1 million in the first nine months of 2006.

Water Transmission sales decreased slightly to $63.9 million in the third quarter of 2007 from $65.5 million in the third quarter of 2006 and increased 14.6% to $197.9 million in the first nine months of 2007 from $172.8 million in the
first nine months of 2006. Net sales for the nine months ended September 30, 2007, increased over the same period last year as a result of a consistent higher production level in most of our facilities. The higher production resulted from the
increased backlog at the beginning of 2007 of $198.2 million compared to $125.6 million at the beginning of 2006. This allowed the majority of our facilities to increase plant utilization in the first quarter of 2007 and, combined with solid
bookings early in the year, maintain this level of production through the third quarter of 2007. Bookings were lower than expected during the third quarter, which resulted in a backlog of approximately $174 million at September 30, 2007. Even
though our backlog decreased in the third quarter of 2007, we expect production in the fourth quarter to increase from the third quarter levels as projects enter the production process. Bidding activity is expected to be strong in the fourth quarter
of 2007. Bidding activity, backlog and sales resulting from the award of new projects, or the production of current projects, may vary significantly from period to period.

Tubular Products sales increased 13.2% to $25.2 million in the third quarter of 2007 from $22.3 million in the third quarter of 2006 and increased 20.9% from $63.8 million in the first nine months of 2006 to $77.1
million in the first nine months of 2007. The majority of the increase in net sales over the same periods last year resulted primarily from increased energy and construction product sales. Beginning in the fourth quarter of 2005, we sold our energy
products through a strategic alliance with U.S. Steel. This alliance was discontinued in the third quarter of 2007. This will temporarily lower our energy sales for

the next few quarters, until we see the benefits from the sales agreement we entered in to during the third quarter of 2007 with LSS Group of Houston, Texas.
In addition, we normally see lower sales in the fourth and first quarters because of normal seasonality in the other product lines.

Fabricated Products
sales decreased to $2.9 million in the third quarter of 2007 from $4.7 million in the third quarter of 2006 and decreased from $12.6 million in the first nine months of 2006 to $9.6 million in the first nine months of 2007. The decrease in net sales
over the same periods last year resulted from the continued soft propane tank market.

During the three months and nine months ended September 30,
2007 and 2006, no customer accounted for more than 10.0% of net sales.

Gross Profit/(Loss).Gross profit increased 13.7% to $17.3 million
(18.8% of total net sales) in the third quarter of 2007 from $15.2 million (16.5% of total net sales) in the third quarter of 2006 and increased 28.9% from $40.5 million (16.3% of total net sales) in the first nine months of 2006 to $52.2 million
(18.3% of total net sales) in the first nine months of 2007.

Water Transmission gross profit increased 12.7% to $14.3 million (22.5% of segment net sales)
in the third quarter of 2007 from $12.7 million (19.4% of segment net sales) in the third quarter of 2006 and increased 31.8% from $32.7 million (18.9% of segment net sales) in the first nine months of 2006 to $43.1 million (21.8% of segment net
sales) in the first nine months of 2007. Water Transmission gross profit increased for the three and nine months ended September 30, 2007 over the same period last year due to higher plant utilization, a favorable mix of projects being produced
and the reduction of rent expense as a result of the purchase in the fourth quarter of 2006 of manufacturing equipment that we previously leased under certain operating leases.

Gross profit from Tubular Products increased 37.5% to $3.1 million (12.2% of segment net sales) in the third quarter of 2007 from $2.2 million (10.1% of segment net sales) in the third quarter of 2006 and increased
32.6% to $9.0 million (11.7% of segment net sales) in the first nine months of 2007 from $6.8 million (10.7% of segment net sales) in the first nine months of 2006. The majority of the increase in gross profit is a result of higher volume. The
margin as a percentage of segment net sales improved due to higher plant utilization and product mix.

The Fabricated Products Group generated a loss of
$123,000 ((4.2)% of segment net sales) in the third quarter of 2007 compared to a $243,000 gain (5.2% of segment net sales) in the third quarter of 2006 and decreased to $48,000 (0.5% of segment net sales) in the first nine months of 2007 from
$960,000 (7.6% of segment net sales) in the first nine months of 2006. Fabricated Products gross profit decreased for the three and nine months ended September 30, 2007 over the same period last year primarily as a result of our inability to
pass on higher steel and freight costs, due to the slow market for propane tanks.

Selling, General and Administrative Expenses.Selling,
general and administrative expenses increased to $7.6 million (8.3% of total net sales) in the third quarter of 2007 from $7.0 million (7.6% of total net sales) in the third quarter of 2006 and increased to $22.9 million (8.0% of total net sales) in
the first nine months of 2007 from $20.3 million (8.2% of total net sales) in the first nine months of 2006. The increase from the same periods last year was primarily attributable to higher incentive compensation expense, higher professional fees
and increased stock options expense. In addition, in the first nine months of 2007, the settlement of a number of outstanding customer claims contributed to the increase over the prior period.

Interest Expense, net.Interest expense, net decreased slightly to $1.7 million in the third quarter of 2007 from $1.8 million in the third quarter of 2006
and decreased to $5.1 million in the first nine months of 2007 from $5.3 million in the first nine months of 2006. The decrease in interest expense in the three months ended September 30, 2007 compared to the same period last year resulted from
capitalization of interest expense to capital projects. In addition, the collection of interest income from customers also resulted in a lower expense during the first nine months of 2007 as compared to the same period in the prior year.

Income Taxes.The provision for income taxes was $9.0 million in the first nine months of 2007, based on an effective tax rate of approximately 37.0%,
compared to $8.5 million in the first nine months of 2006, based on an effective tax rate of approximately 37.7%.

Liquidity and Capital Resources

We finance operations with internally generated funds and available borrowings. At September 30, 2007, we had cash and cash equivalents of $191,000.

Net cash provided by operating activities in the first nine months of 2007 was $10.6 million. This was primarily the result of our net income of $15.3
million, non-cash adjustments for depreciation and amortization of property and equipment of $3.7 million, a decrease in inventories and trade and other receivables, net of $21.8 million and $3.9 million, respectively, and an

increase in accrued and other liabilities of $7.8 million. Offsetting these inflows, in part, was a decrease in accounts payable of $30.6 million and an
increase in costs and estimated earnings in excess of billings of $14.4 million. The decrease in inventories, trade and other receivables, net and the increase in costs and estimated earnings in excess of billings resulted from timing differences
between production, shipment and invoicing of products. At the end of 2006, we saw an increase in steel shipments from our vendors, which resulted in an increase in inventory and accounts payable at that time.

Net cash used in investing activities in the first nine months of 2007 was $17.8 million, which resulted from additions of property and equipment and the purchase of
certain equipment acquired through the purchase of Continental Pipe Company. Capital expenditures are expected to be between $20.0 million and $23.0 million in 2007, including the Continental acquisition.

Net cash provided by financing activities in the first nine months of 2007 was $3.1 million, which resulted primarily from the payoff of Series B Senior Notes for $8.6
million and Senior Notes for $5.0 million, offset by increased net borrowings under the notes payable to financial institutions of $15.3 million.

We had
the following significant components of debt at September 30, 2007: a $90.0 million credit agreement, under which $58.3 million was outstanding; $15.0 million of Series A Term Note; $10.5 million of Series B Term Notes; $10.0 million of Series
C Term Notes; $4.5 million of Series D Term Notes and a $3.8 million Industrial Revenue Bond.

On May 31, 2007, the Company entered into an Amended
and Restated Credit Agreement (Amended Credit Agreement). The Amended Credit Agreement amends and restates the Credit Agreement dated May 20, 2005, and provides for a revolving loan, swing line loan and letters of credit in the
aggregate amount of up to $90 million, with an option for the Company to increase that amount to $110 million upon lender approval. Borrowings under the Amended Credit Agreement are secured by substantially all of the Companys accounts
receivable, inventory and certain machinery and equipment.

Also on May 31, 2007, the Company entered into an Amended and Restated Note Purchase and
Private Shelf Agreement, which reflects favorable changes in certain financial covenants and other changes to generally conform to the Amended Credit Agreement. The Company may issue additional notes under the Amended and Restated Note Purchase and
Private Shelf Agreement in the aggregate principal amount of up to $35 million.

The credit agreement expires on May 31, 2012. The balance outstanding
under the credit agreement bears interest at rates related to LIBOR plus 0.75% to 1.625%, or the lending institutions prime rate, minus 0.5% to 0.0%. At September 30, 2007, we had $58.3 million outstanding under the credit facility
bearing interest at a weighted average rate of 6.64%. At September 30, 2007 we had an additional net borrowing capacity under the credit facility of $39.1 million.

The Series A Term Note in the principal amount of $15.0 million matures on February 25, 2014 and requires annual payments in the amount of $2.1 million that begin February 25, 2008 plus interest of 8.75%
paid quarterly on February 25, May 25, August 25 and November 25. The Series B Term Notes in the principal amount of $10.5 million mature on June 21, 2014 and require annual payments in the amount of $1.5 million
that begin June 21, 2008 plus interest of 8.47% paid quarterly on March 21, June 21, September 21 and December 21. The Series C Term Notes in the principal amount of $10.0 million mature on October 26, 2014 and require
annual payments of $1.4 million that begin October 26, 2008 plus interest of 7.36% paid quarterly on January 26, April 26, July 26 and October 26. The Series D Term Notes in the principal amount of $4.5 million mature on
January 24, 2015 and require annual payments in the amount of $643,000 that begin January 24, 2009 plus interest of 7.32% paid quarterly on January 24, April 24, July 24, and October 24. The Industrial Revenue Bond in
the principal amount of $3.8 million matures on July 1, 2016 and requires monthly principal and interest payments, at 5.22%, in the amount of $50,000 that began February 1, 2007. The Series A Term Note, the Series B Term Notes, the Series
C Term Notes, and the Series D Term Notes (together, the Term Notes) and the credit agreement are collateralized by accounts receivable, inventory and certain equipment.

We lease certain equipment used in the manufacturing process. The average interest rate on the capital leases is 5.7%.

We
also have entered into stand-by letters of credit that total approximately $13.6 million as of September 30, 2007. The stand-by letters of credit relate to customer owned material, workers compensation and general liability insurance. Due
to the nature of these arrangements and our historical experience, we do not expect to make any significant payments under these arrangements.

The credit
agreement, the Term Notes and certain of our capital leases all require compliance with the following financial covenants: minimum consolidated tangible net worth, maximum consolidated total debt to consolidated earnings before interest, taxes,
depreciation and amortization (EBITDA) ratio, a minimum consolidated fixed charge coverage ratio and a minimum asset coverage ratio. These and other covenants included in our financing agreements impose certain requirements with respect to our
financial condition and results of operations, and place restrictions on, among other things, our ability to

incur certain additional indebtedness, to create liens or other encumbrances on assets and capital expenditures. A failure by us to comply with the
requirements of these covenants, if not waived or cured, could permit acceleration of the related indebtedness and acceleration of indebtedness under other instruments that include cross-acceleration or cross-default provisions. At
September 30, 2007, we were not in violation of any of the covenants in our debt agreements.

We expect to continue to rely on cash generated from
operations and other sources of available funds to make required principal payments under the Notes during 2007. We anticipate that our existing cash and cash equivalents, and amounts available under our credit agreement will be adequate to fund our
working capital and capital requirements for at least the next twelve months. To the extent necessary, we may also satisfy capital requirements through additional bank borrowings, senior notes, term notes and capital and operating leases, if such
resources are available on satisfactory terms. We have from time to time evaluated and continue to evaluate opportunities for acquisitions and expansion. Any such transactions, if consummated, may use a portion of our working capital or necessitate
additional bank borrowings.

Off Balance Sheet Arrangements

Other than operating lease commitments, we do not have off-balance sheet arrangements, financings, or other relationships with unconsolidated entities or other persons, also known as special purpose entities.



|Item 3. | Quantitative and Qualitative Disclosure About Market Risk
|------- | ---------------------------------------------------------

We transact business in various foreign countries, and from time to time settle our transactions in foreign currencies. We have established a program that utilizes foreign currency forward contracts to offset the risk associated with the
effects of certain foreign currency exposures. These forward contracts are not used for trading or for speculative purposes. Our foreign currency exposures typically arise from sales contracts denominated in Canadian currency, for which there is
exposure associated with potential foreign currency rate changes occurring between the contract date and the date when the payments are received. Under this program, increases or decreases in our foreign currency exposures are offset by gains or
losses on the forward contracts, to mitigate the possibility of foreign currency transaction gains or losses. We have 13 Foreign Exchange Agreements (Agreements) at September 30, 2007, which were for an original amount of $44.8
million, of which $31.2 million was still open. Net foreign exchange transaction gains (losses) included in the accompanying consolidated statements of operations were not material for the three and nine months ended September 30, 2007 and
2006, respectively. We believe our current risk exposure to exchange rate movements to be de minimis.

We are exposed to cash flow and fair value risk due
to changes in interest rates with respect to certain portions of our debt. The debt subject to changes in interest rates is our $90.0 million revolving credit line ($58.3 million outstanding as of September 30, 2007). We believe our current
risk exposure resulting from interest rate movements to be immaterial.

Additional information required by this item is set forth in Item
2Managements Discussion and Analysis of Financial Condition and Results of OperationsLiquidity and Capital Resources.



|Item 4. | Controls and Procedures
|------- | -----------------------

As of September 30, 2007, the
end of the period covered by this report, our Chief Executive Officer and our Chief Financial Officer reviewed and evaluated the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e) and 15d-15(e)), which
are designed to ensure that material information we must disclose in our report filed or submitted under the Securities Exchange Act of 1934, as amended (the Exchange Act) is recorded, processed, summarized, and reported on a timely
basis. Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that as of such date, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in
reports that we file or submit under the Exchange Act is accumulated and communicated as appropriate to allow timely decisions regarding required disclosure.

In the three months ended September 30, 2007, there has been no change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal controls over financial
reporting.
