|3. | 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 was 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 Portland Harbor Site, or Site). 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 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.

In
December 2000, EPA and ODEQ 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 encouraged the Company and other notice recipients to voluntarily enter into negotiations to participate in a remedial investigation and feasibility study (RI/FS).
The RI/FS is currently being directed by a group of potentially responsible parties known as the Lower Willamette Group (LWG). The Company, along with several other parties, reached an Interim RI/FS settlement in February 2007. Under
this agreement the Company made a payment of $175,000 in June 2007 to the LWG. This was an interim settlement only and does not obligate the Company to any further payment or liabilities.

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.

In November 2007, EPA invited the notice recipients to a meeting in Portland to discuss the current status of the RI/FS and how that relates to the timing and scope of
future negotiations concerning the cleanup of the Portland Harbor Site. At that meeting EPA stated that additional parties would be notified of their potential responsibility. In January 2008, EPA sent notices to over two hundred additional parties
bringing the total number of parties receiving notice from EPA to 280. At the same time, pursuant to CERCLA section 104(e), EPA requested information concerning site history and operations from every notice recipient, including the Company. The
responses to EPA were initially due May 16, 2008. The Company and many other notice recipients requested and received extensions to this deadline.

Concurrent with the activities of EPA and ODEQ, the Portland Harbor Natural Resources Trustee Council (Trustees) sent some or all of the same parties, including the Company, a notice of intent to perform an Injury Assessment for
the Portland Harbor Site to determine the nature and extent of natural resource damages under CERCLA section 107. Natural resource damages focus on site restoration as opposed to actions to remove or remediate hazardous substances. The Trustees for
the Portland Harbor Site consist of representatives from six Northwest Indian Tribes and three federal agencies. The Trustees act independently of EPA and ODEQ but the Company expects their assessment will be coordinated with the RI/FS work underway
at the Portland Harbor Site. The Trustees have encouraged potentially responsible parties to voluntarily participate in the funding of their injury assessment. The Company has not assumed any payment obligation or liability related to the
Trustees assessment.

The extent of our participation in this work is not known, and no adjustments to the consolidated financial statements have
been recorded for this matter as of June 30, 2008.

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.

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, results of operations or cash flows.



|4. | Water Transmission Revenue Recognition
|-- | --------------------------------------

Revenue from construction
contracts in the Companys water transmission segment is recognized on the percentage-of-completion method, measured by the percentage of total costs incurred to date to the estimated total costs of each contract. Estimated total costs are
reviewed monthly and updated by project management and operations personnel for all projects that are fifty percent or more complete, except that major projects, usually over $5.0 million, are reviewed earlier if sufficient production has been
completed to provide enough information to revise the original estimated total cost of the project. All cost revisions that result in the gross profit as a percent of sales increasing or decreasing by greater than two percent are reviewed by senior
management personnel. Provisions for estimated losses on uncompleted contracts are made in the period such estimated losses are known. Changes in job performance, job conditions and estimated profitability, including those arising from contract
penalty provisions, and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Contract costs include all direct material and labor costs and those indirect
costs related to contract performance, such as indirect labor, supplies, tools, repairs and depreciation. Selling, general and administrative costs are charged to expense as incurred. While certain contract costs are reported in the consolidated
statements of income as selling, general and administrative costs, they are included in total contract costs incurred to date used in the percentage-of-completion calculation. For the three and six months ended June 30, 2008 and

2007, contract costs of $1.1 million and $3.6 million and $2.1 million and $4.0 million, respectively, are reported in the consolidated statements of income
as selling, general and administrative costs, but have been included in total contract costs incurred to date used in the percentage-of-completion calculation of costs and estimated earnings in excess of billings.



|5. | Segment Information
|-- | -------------------

The Companys operations are organized in
two reportable segments, the Water Transmission Group and the Tubular Products Group, which are based on the nature of the products and the manufacturing process. The Water Transmission Group manufactures large-diameter, high-pressure steel pipeline
systems for use in water infrastructure applications, primarily related to drinking water systems. The pipeline systems are also used for hydroelectric power systems, wastewater systems and other applications. In addition, the Water Transmission
Group makes products for industrial plant piping systems and certain structural applications. The Tubular Products Group produces a range of products used in several different markets, including energy pipe, fire protection sprinkler pipe,
agricultural pipe, traffic signpost systems and standard pipe that is used in many different applications. These two segments represent distinct business activities, which management evaluates based on segment gross profit. There were no material
transfers between segments in the periods presented.

Historically, the Company disclosed three segments, but based on changes in organizational structure
and strategic direction, the resulting reporting of segments changed. The Company has conformed prior periods segment information to be consistent with the current reporting and operating structure in place.

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

The Company has one active stock
incentive plan for employees and directors, the 2007 Stock Incentive Plan, which 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. In addition, the Company has two inactive stock option plans; the 1995 Stock Option Plan for Nonemployee Directors and the Amended 1995 Stock Incentive Plan, under which previously granted options remain outstanding. There were 885,872
shares of common stock reserved for issuance under the Companys stock compensation plans at June 30, 2008, against which 295,908 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.

The total intrinsic value, defined as the difference between the current market value and the grant price, of
options exercised or exchanged during the six months ended June 30, 2008 was $2.6 million.

For the three month period ended June 30, 2008, 1,036 stock awards were granted to non-employee directors,
which vested immediately upon issuance. In accordance with SFAS 123(R), the Company recorded compensation expense based on the fair market value of the awards on the grant date of $47.73. For the three and six month periods ended June 30, 2008,
total share-based compensation expense of $33,000 and $49,000, 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 $20,000 and
$30,000, respectively. For the three and six months ended June 30, 2007, total share-based compensation expense of $274,000 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 $173,000 and $187,000, respectively. As of June 30, 2008, all outstanding options are fully vested and there is no unrecognized compensation expense.



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

The Company files income tax returns in the United
States Federal jurisdiction, in one foreign 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 is currently
attempting to resolve income tax audits relating to the 2005 tax filings in various jurisdictions, and to certain amendments filed.

The Company had $1.3
million and $956,000 of unrecognized tax benefits at June 30, 2008 and December 31, 2007, respectively, which would favorably affect the effective tax rate in a future period if recognized. Of the $1.3 million, the Company believes it is
reasonably possible the total amounts of unrecognized tax benefits will decrease by $959,000 in the following twelve months, based upon resolution of the audits; however, it is not possible to quantify the impact the decrease, if any, would have on
the effective tax rate and on net income due to the inherent complexities of the audits. Resolution of the audits could have an impact on the effective tax rate and on net income, either favorably (principally as a result of settlements that are
less than the liability for unrecognized tax benefits) or unfavorably (if such settlements exceed the liability for unrecognized tax benefits).

The
Company recognizes interest and penalties related to uncertain tax positions in income tax expense.

##### Table of Contents

The Company provided for income taxes at estimated effective tax rates of 40% and 39% for the three and six month periods
ended June 30, 2008, and 37% for the three and six month periods ended June 30, 2007.



|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 197,440 and 280,653 for the three months ended June 30, 2008 and 2007, respectively, and incremental shares of 210,659 and 284,807 for the six months ended June 30, 2008 and
2007, respectively, were used in the calculations of diluted earnings per share. For the three and six months ended June 30, 2008 and 2007, the calculation of diluted earnings per share included all common equivalent shares.



|9. | Fair Value Measurement
|-- | ----------------------

Effective January 1, 2008, the Company
adopted Statement of Financial Accounting Standard (SFAS) No. 157 Fair Value Measurements (SFAS 157), as described in Note 10. SFAS 157 establishes a fair value hierarchy which prioritizes the inputs to
valuation techniques used to measure fair value into three broad levels. These levels are: Level 1 (inputs are quoted prices in active markets for identical assets or liabilities); Level 2 (inputs are other than quoted prices that are observable,
either directly or indirectly through corroboration with observable market data); and Level 3 (inputs are unobservable, with little or no market data that exists).

The following table summarizes information regarding the Companys financial assets and financial liabilities that are measured at fair value as of June 30, 2008 (in thousands):



|            |  |                      |       |         |   |         |  |         |       |  |   |

The Company uses derivatives to offset the risk associated with the effects of certain foreign currency exposures.
These contracts are not for trading or for speculative purposes. Fair value measurements for the Companys derivatives are classified under Level 2 because such measurements are based on third-party valuation models.



|10. | Recent Accounting and Reporting Developments
|--- | --------------------------------------------

In March 2008, the
Financial Accounting Standards Board (FASB) issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB Statement No. 133 (SFAS 161). SFAS 161 amends and
expands the disclosure requirements of SFAS 133 with the intent to provide users of financial statements with an enhanced understanding of: 1) How and why an entity uses derivative instruments; 2) How derivative instruments and related hedged items
are accounted for under SFAS 133 and its related interpretations and 3) How derivative instruments and related hedged items affect an entitys financial position, financial performance and cash flows. This statement is effective for financial
statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged. The adoption of SFAS 161 relates specifically to disclosures, and will not have an impact on the Companys
financial position, results of operations or cash flows.

In December 2007 the FASB issued SFAS No. 141(R), Business Combinations
(SFAS 141(R)), which requires the acquiring entity in a business combination to recognize and measure all assets and liabilities assumed in the transaction and any non-controlling interest in the acquiree at fair value as of the
acquisition date. SFAS 141(R) also establishes guidance for the measurement of the acquirer shares issued in consideration for a business combination, the recognition of contingent consideration, the accounting treatment for pre-acquisition gain and
loss contingencies, the treatment of acquisition related transaction costs, and the recognition of changes in the acquirer's income tax valuation allowance and deferred taxes. SFAS 141(R) is effective for fiscal years beginning after
December 15, 2008, and is to be applied prospectively as of the beginning

of the fiscal year in which the statement is applied. Early adoption is not permitted. The Company is currently evaluating the impact of SFAS 141(R) on the
financial position, results of operations and cash flows when effective, but the nature and magnitude of the specific effects will depend upon the nature, terms, and size of the acquisitions the Company consummates after the effective date.

In February 2007 the 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, which would not otherwise be measured 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 adoption of SFAS 159 on January 1, 2008, did not have an impact on the Condensed Consolidated Financial Statements.

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. FASB Staff Position (FSP) SFAS 157-2 was issued in February 2008 and deferred the effective date of SFAS 157 to fiscal years beginning
after November 15, 2008 for nonfinancial assets and nonfinancial liabilities. Accordingly, the Company adopted SFAS 157 as of January 1, 2008 for financial assets and liabilities only. The adoption of SFAS 157 for financial assets and
financial liabilities did not have an impact on the Condensed Consolidated Financial Statements. The full adoption of SFAS 157 in 2009 for nonfinancial assets and nonfinancial liabilities is also not expected to have a significant impact on the
Companys financial position, results of operations or cash flows.

Overview

Our Water Transmission Group is the 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 from seven manufacturing facilities strategically located across the United
States in Portland, Oregon; Denver, Colorado; Adelanto, California; Parkersburg, West Virginia; Saginaw, Texas; Pleasant Grove, Utah, and Monterrey, Mexico. Our Water Transmission Group accounted for approximately 67% of net sales in the first half
of 2008.

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.

Our Tubular Products Group operates two manufacturing facilities in Atchison, Kansas, and Houston, Texas. We also own a
facility in Bossier City, Louisiana, which has temporarily suspended operations. We produce a range of products used in several different markets. We currently make mechanical tubing, energy pipe, fire protection sprinkler pipe, agricultural pipe,
traffic signpost systems and structural tubing that is sold to distributors and used in many different applications. Our Tubular Products Group generated approximately 33% of net sales in the first half of 2008.

Our Tubular Products Groups sales volume is typically driven by non-residential construction spending, energy spending, highway spending, agricultural spending and
general economic conditions. We focus on products for which we believe we have a sustainable advantage.

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, 2007.

Recent Accounting Pronouncements

See Note 10 of the Consolidated
Financial Statements for a description of recent accounting pronouncements, including the expected dates of adoption and estimated effects on results of operations and financial position.

Three Months and Six Months Ended June 30, 2008 Compared to Three Months and Six Months Ended
June 30, 2007

Net Sales.Net sales increased 10.0% to $112.1 million for the second quarter of 2008 compared to $101.9 million for
the second quarter of 2007, and increased 7.0% to $206.1 million in the first six months of 2008 from $192.6 million in the first six months of 2007.

Water Transmission sales increased 2.6% to $74.9 million in the second quarter of 2008 from $73.0 million in the second quarter of 2007 and decreased 1.4% to $138.7 million in the first half of 2008 from $140.7 million in the first half of
2007. Net sales for the three months and the six months ended June 30, 2008 fluctuated slightly from the same periods in the prior year as a result of timing of production in certain of our facilities. 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 28.8% to $37.2 million in the second quarter of 2008 from $28.9 million in the second quarter of 2007 and increased 29.8% from $51.9 million in the first half of 2007 to $67.4 million in the first half of 2008. Sales increased over the
same periods last year due to increased prices and increased sales of energy products, fire protection sprinkler pipe and agricultural products.

During
the six months ended June 30, 2008 and 2007, no single customer accounted for 10% or more of net sales. During the three months ended June 30, 2008, one customer accounted for 11.4% of net sales. During the three months ended June 30,
2007, one customer accounted for 10.7% of net sales.

Gross Profit.Gross profit increased 31.0% to $24.6 million (22.0% of total net sales)
in the second quarter of 2008 from $18.8 million (18.4% of total net sales) in the second quarter of 2007 and increased 21.5% from $34.9 million (18.1% of total net sales) in the first half of 2007 to $42.4 million (20.6% of total net sales) in the
first half of 2008.

Water Transmission gross profit decreased $386,000, or 2.5%, to $14.8 million (19.7% of segment net sales) in the second quarter of
2008 from $15.2 million (20.8% of segment net sales) in the second quarter of 2007 and increased $273,000, or 0.9% from $29.0 million (20.6% of segment net sales) in the first half of 2007 to $29.2 million (21.1% of segment net sales) in the first
half of 2008. Water Transmission gross profit as a percentage of segment net sales decreased for the three months ended June 30, 2008 over the same period last year due to the effect of higher steel costs, which partially offset the somewhat
better pricing and improved operational efficiencies experienced in the first quarter of 2008.

Gross profit from Tubular Products increased 171.2% to $9.8
million (26.4% of segment net sales) in the second quarter of 2008 from $3.6 million (12.5% of segment net sales) in the second quarter of 2007 and increased 121.8% to $13.2 million (19.5% of segment net sales) in the first half of 2008 from $5.9
million (11.4% of segment net sales) in the first half of 2007. The majority of the increase in gross profit is a result of increased selling prices.

Selling, General and Administrative Expenses.Selling, general and administrative expenses increased to
$9.3 million (8.3% of total net sales) in the second quarter of 2008 from $8.0 million (7.8% of total net sales) in the second quarter of 2007 and increased to $17.2 million (8.4% of total net sales) in the first six months of 2008 from $15.3
million (7.9% of total net sales) in the first six months of 2007. The increase from the same periods last year was primarily attributable to higher salary and wage expense, including sales commissions, increased professional fees, and the costs
associated with the move of the headquarters to Vancouver, Washington.

Interest Expense, net.Interest expense, net decreased to $1.3
million in the second quarter of 2008 from $1.8 million in the second quarter of 2007 and decreased to $3.1 million in the first six months of 2008 from $3.4 million in the first six months of 2007. The decrease in the expense compared to the same
periods last year was a result of lower average interest rates.

Income Taxes.The provision for income taxes was $5.6 million in the second
quarter of 2008, based on an effective tax rate of approximately 40.0%, compared to $3.3 million for the same period last year, based on an expected tax rate of approximately 37.0%. The provision for income taxes was $8.6 million for the first six
months of 2008, based on an effective tax rate of approximately 38.9%, compared to $6.0 million for the same period last year, based on an effective tax rate of approximately 37.0%. The increase in our effective tax rate was mainly due to the
additional accrual of a contingent liability related to ongoing income tax audits.

Liquidity and Capital Resources

Sources and Uses of Cash

Our principal sources of liquidity
generally include operating cash flow and our bank credit agreement. From time to time our long term capital needs may be met through the issuance of long term debt or additional equity. Our principal uses of liquidity generally include capital
expenditures, working capital and debt service. Information regarding our cash flows for the three months ended June 30, 2008 is presented in our consolidated statements of cash flows contained in this Form 10-Q, and is further discussed below.

As of June 30, 2008, our working capital (current assets minus current liabilities) was $198.0 million as compared to $181.5 million as of
December 31, 2007.

Net cash provided by operating activities in the first six months of 2008 was $225,000. This was primarily the result of our net
income of $13.4 million combined with a decrease in costs and estimated earnings in excess of billings on uncompleted contracts, net of $15.6 million and an increase in accounts payable of $5.3 million, offset in part by an increase in trade and
other receivables, net of $34.0 million. The decrease in costs and estimated earnings in excess of billings on uncompleted contracts and the increase in trade and other receivables and accounts payable resulted from timing differences between
production, shipment and invoicing of products. We are typically obligated to pay for goods and services within 30 days of receipt, while cash collected from our construction contracts typically extends for several months. Our construction contract
revenues in the water transmission segment are recognized on a percentage-of-completion method; therefore, there is little correlation between revenue and cash receipts and the elapsed time can be significant. As such, our payment cycle is a
significantly shorter interval compared to our collection cycle.

Net cash used in investing activities in the first six months of 2008 was $11.9 million,
which resulted from additions of property and equipment across all of our facilities; the most significant of which was two new spiral weld mills. Capital expenditures are expected to be between $15.0 million and $20.0 million in 2008, excluding the
costs of a new facility in Houston.

Net cash provided by financing activities in the first six months of 2008 was $11.6 million, which resulted primarily
from increased net borrowings under the notes payable to financial institutions of $13.4 million, which was used to fund operating and investing activities.

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. We also expect to
continue to rely on cash generated from operations and other sources of available funds to make required principal payments under our long term debt during 2008. 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. 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.

Debt

We had
the following significant components of debt at June 30, 2008: a $100.0 million credit agreement, under which $67.8 million was outstanding; $12.9 million of Series A Term Note, $9.0 million of Series B Term Notes, $10.0 million of Series C
Term Notes and $4.5 million of Series D Term Notes.

There have been no changes to the scheduled maturities of the Series A Term Note, the Series B Term
Notes, the Series C Term Notes, or the Series D Term Notes (together, the Term Notes) from that disclosed in our Annual Report on Form 10-K for the year ended December 31, 2007. The Term Notes are collateralized by accounts
receivable, inventory and certain machinery and equipment.

We also have entered into stand-by letters of credit that total approximately $14.1 million as
of June 30, 2008. The stand-by letters of credit relate to customer owned material and workers compensation insurance. Due to the nature of these arrangements and our historical experience, we do not expect to make any material payments
under these arrangements.

The credit agreement provides for a revolving loan, swing line loan and letters of credit in the aggregate amount of up to $100
million, with an option for the Company to increase that amount to $110 million upon lender approval. Borrowings under the credit agreement are secured by substantially all of the Companys accounts receivable, inventory and certain
machinery and equipment.

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 June 30, 2008, we had $67.8 million outstanding under the credit facility bearing interest at a weighted average rate of 3.90%.

We had $4.4 million of capital leases outstanding at June 30, 2008, under which certain equipment used in the manufacturing process is leased. The
average interest rate on the capital leases is 5.7%.

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 June 30, 2008, we were not in violation of any of the covenants in our debt agreements.

Off Balance Sheet Arrangements

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

for the year ended December 31, 2007. For the six months ended June 30, 2008, there has been no material change in market risk factors.



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

As of June 30, 2008, 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.
