|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.

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 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. ODEQ is expected to make its recommendations by mid-2007.

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 its results of operations or financial condition.

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.

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

The Company has two stock option plans
for employees and directors. The 2007 Stock Incentive Plan, which was approved by stockholders 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 and continue to vest. There were 1,107,380 shares of common stock reserved for
issuance under the Companys stock compensation plans at June 30, 2007, against which 513,380 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 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. For the three and six month periods ended June 30, 2006, total share-based
compensation expense of $126,000 and $200,000, 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 $78,000 and $123,000,
respectively. As of June 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 six months ended June 30, 2007 was $318,000.

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
June 30, 2007, we have $835,000 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.

We recognize interest and penalties related to uncertain tax positions in income tax expense. As of June 30, 2007, we have approximately $28,000 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 280,653 and 277,010 for the three months ended June 30, 2007 and 2006, respectively, and incremental shares of 284,807 and 280,342 for the six months ended June 30, 2007 and
2006, respectively, were used in the calculations of diluted

earnings per share. For the three and six months ended June 30, 2007, the calculation of diluted earnings per share included all common equivalent
shares. For the three and six months ended June 30, 2006, options to purchase 3,495 and 1,757 shares, respectively, 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. | Related Party Transactions
|-- | --------------------------

The Company has ongoing business
relationships with certain affiliates of Wells Fargo & Company (Wells Fargo). Wells Fargo, together with certain of its affiliates, owns more than 10 percent of our common stock, and is therefore considered a related party.
During the three and six months ended June 30, 2007, the Company made payments to affiliates of Wells Fargo for operating and capital lease payments, pursuant to which the Company leases certain equipment from such affiliates. During the three
and six months ended June 30, 2006, we made payments to affiliates of Wells Fargo for operating lease payments, pursuant to which the Company leases certain equipment from such affiliates. Payments made by the Company to Wells Fargo and its
affiliates amounted to $108,000 and $214,000, respectively, for the three and six months ended June 30, 2007, and $87,000 and $225,000, respectively, for the three and six months ended June 30, 2006. Balances due to Wells Fargo and its
affiliates were $1.3 million at June 30, 2007 and $0 at December 31, 2006.



|10. | 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.

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 strengths.

Our Tubular Products Groups sales volume is typically driven by non-residential construction spending, energy, 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 Six Months Ended June 30, 2007 Compared to Three Months and Six Months Ended
June 30, 2006

Net Sales.Net sales increased 30.9% to $101.9 million for the second quarter of 2007 compared to $77.9 million for
the second quarter of 2006, and increased 23.0% to $192.6 million in the first six months of 2007 from $156.7 million in the first six months of 2006.

Water Transmission sales increased 35.3% to $69.5 million in the second quarter of 2007 from $51.3 million in the second quarter of 2006 and increased 24.9% to $134.1 million in the first half of 2007 from $107.3 million in the first half
of 2006.

##### Table of Contents

Net sales for the three months and the six months ended June 30, 2007, increased over the same period last year as a result of higher production 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 maintain this level of production through the second quarter of 2007. While bookings were lower than expected, they were strong enough to allow us to maintain our backlog at approximately $192 million at the end of the
second 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 28.0% to $28.9 million in the second quarter of 2007 from $22.6 million in the second quarter of 2006 and increased 25.1% from $41.5 million in the first half of 2006 to $51.9 million
in the first half of 2007. The majority of the increase in net sales over the same periods last year resulted from increased energy product sales. We expect sales to continue close to this level in the third quarter of 2007, but decrease in the
fourth quarter of 2007 as a result of normal seasonality.

Fabricated Products sales decreased to $3.5 million in the second quarter of 2007 from $3.9
million in the second quarter of 2006 and decreased from $7.9 million in the first half of 2006 to $6.7 million in the first half of 2007. The decrease in net sales over the same periods last year resulted from a softening in the propane tank
market.

During the three months ended June 30, 2007, one customer accounted for 10.7% of net sales. No single customer accounted for 10% or more of
net sales in the first six months of 2007, nor the first six months or second quarter of 2006.

Gross Profit.Gross profit increased 46.8% to
$18.8 million (18.4% of total net sales) in the second quarter of 2007 from $12.8 million (16.4% of total net sales) in the second quarter of 2006 and increased 38.1% from $25.3 million (16.1% of total net sales) in the first half of 2006 to $34.9
million (18.1% of total net sales) in the first half of 2007.

Water Transmission gross profit increased 53.3% to $15.1 million (21.7% of segment net
sales) in the second quarter of 2007 from $9.8 million (19.1% of segment net sales) in the second quarter of 2006 and increased 44.0% from $20.0 million (18.6% of segment net sales) in the first half of 2006 to $28.8 million (21.5% of segment net
sales) in the first half of 2007. Water Transmission gross profit increased for the three and six months ended June 30, 2007 over the same period last year due to higher plant utilization and the reduction of rent expense as a result of the
purchase in the fourth quarter of 2006 of manufacturing equipment that we leased under certain operating leases.

Gross profit from Tubular Products
increased 36.7% to $3.6 million (12.5% of segment net sales) in the second quarter of 2007 from $2.7 million (11.7% of segment net sales) in the second quarter of 2006 and increased 30.2% to $5.9 million (11.4% of segment net sales) in the first
half of 2007 from $4.6 million (11.0% of segment net sales) in the first half 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 slightly due in part to higher
plant utilization and product mix.

Gross profit from Fabricated Products decreased to $113,000 (3.2% of segment net sales) in the second quarter of 2007
from $334,000 (8.5% of segment net sales) in the second quarter of 2006 and decreased to $171,000 (2.6% of segment net sales) in the first half of 2007 from $717,000 (9.1% of segment net sales) in the first half of 2006. Fabricated Products gross
profit decreased for the three and six months ended June 30, 2007 over the same period last year primarily as a result of our inability to pass on higher steel costs, due to the slow market for propane tanks.

Selling, General and Administrative Expenses.Selling, general and administrative expenses increased to $8.0 million (7.8% of total net sales) in the
second quarter of 2007 from $6.9 million (8.9% of total net sales) in the second quarter of 2006 and increased to $15.3 million (7.9% of total net sales) in the first six months of 2007 from $13.3 million (8.5% of total net sales) in the first six
months of 2006. The increase from the same periods last year was primarily attributable to settling a number of outstanding customer claims, higher incentive compensation expense and increased stock options expense.

Interest Expense, net.Interest expense, net increased to $1.8 million in the second quarter of 2007 from $1.7 million in the second quarter of 2006 and
decreased to $3.4 million in the first six months of 2007 from $3.5 million in the first six months of 2006. The increased expense in the three months ended June 30, 2007 compared to the same period last year was a result of higher average
interest rates. In the first quarter of 2007, the increase in interest expense that resulted from the higher interest rates was reduced by the collection of interest income from customers, resulting in a decrease in expense during the first six
months of 2007 as compared to the same period in the prior year.

Income Taxes.The provision for income taxes was $3.3 million in the second
quarter of 2007, based on an expected tax rate of approximately 37.0%, compared to $4.5 million for the same period last year, based on an expected tax rate of approximately 38.5%. The provision for income taxes was $6.0 million for the first six
months of 2007, based on an expected tax rate of approximately 37.0%, compared to $6.2 million for the same period last year, based on an expected tax rate of approximately 38.5%. The decrease in our effective tax rate was mainly due to the
utilization of research and development tax credits and additional Section 199 manufacturing deductions.

Liquidity and Capital Resources

We finance operations with internally generated funds and available borrowings. At June 30, 2007, we had cash and cash equivalents of $250,000.

Net cash provided by operating activities in the first half of 2007 was $11.7 million. This was primarily the result of our net income of $10.2 million, non-cash adjustments for depreciation and amortization of
property and equipment of $2.5 million, a decrease in inventories, trade and other receivables, net and refundable income taxes of $15.7 million, $2.8 million and $2.4 million, respectively, and an increase in accrued and other liabilities of $3.8
million. Offsetting these inflows, in part, was a decrease in accounts payable of $21.1 million and an increase in costs and estimated earnings in excess of billings of $5.5 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. During the first half of 2007, accounts payable decreased due to the payment for these steel receipts and inventory decreased as steel was used in production.

Net cash used in investing activities in the first half of 2007 was $8.8 million, which resulted from additions of property and equipment. Capital expenditures are
expected to be between $14.0 million and $16.0 million in 2007.

Net cash used in financing activities in the first half of 2007 was $6.8 million, which
resulted primarily from the payoff of Series B Senior Notes for $8.6 million and Senior Notes for $5.0 million, offset in part by increased net borrowings under the notes payable to financial institutions of $6.0 million.

We had the following significant components of debt at June 30, 2007: a $90.0 million credit agreement, under which $49.0 million was outstanding, against which
$4.6 million in cash receipts had not yet been applied to the outstanding balance; $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 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 June 30, 2007, we had $49.0 million outstanding under the credit facility bearing interest at a weighted average rate of 6.48%, partially offset by
$4.6 million in cash receipts that had not been applied to the loan balance. At June 30, 2007 we had an additional net borrowing capacity under the credit facility of $45.6 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.

##### Table of Contents

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 $15.4 million as of June 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 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, 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 had 11 Foreign Exchange Agreements (Agreements) at June 30, 2007, which were for an original amount of $43.0 million,
of which $30.1 million was still open at that date. Net foreign exchange transaction gains (losses) included in the accompanying consolidated statements of operations were not material for the three months ended June 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 ($49.0 million outstanding as of June 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 June 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.
