Forward-looking Statements

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 regarding future events and our future results that are based on
current expectations, estimates, forecasts, and projections about the industries in which we operate and the beliefs and assumptions of our management. Actual results may vary materially from such expectations. Words such as expects,
anticipates, targets, goals, projects, believes, seeks, estimates, plans, or variations of such words and similar expressions, are intended to help
identify such forward-looking statements. In addition, any statements that refer to projections of our future financial performance, our anticipated growth and trends in our businesses, and other characterizations of future events or circumstances,
are forward-looking. For a discussion of the factors that could cause actual results to differ from expectations, please see the risk factors described in Item 1A of our Annual Report on Form 10-K for the year ended September 30, 2007.
There can be no assurance that our results of operations will not be adversely affected by such factors. Unless legally required, we undertake no obligation to revise or update any forward-looking statements for any reason. Readers are cautioned not
to place undue reliance on these forward-looking statements, which speak only as of the date of this report.

HEADWATERS INCORPORATED

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)



|1. | Nature of Operations and Basis of Presentation
|-- | ----------------------------------------------

Description of Business and Organization  Headwaters Incorporated (Headwaters) is incorporated in Delaware and is a diversified company providing products, technologies and services in three industries: building products
(formerly designated construction materials), coal combustion products (CCPs) and energy (formerly alternative energy). Headwaters uses technology to differentiate itself from competitors and to create value in its businesses.

In the building products segment, Headwaters designs, manufactures, and sells architectural stone and resin-based exterior siding accessories (such as
shutters, mounting blocks, and vents) and other products. Headwaters believes that many of its branded products have a leading market position. Revenue from Headwaters building products businesses are diversified geographically and also by
market, including the new construction, remodeling and home improvement markets.

In the CCP segment, Headwaters is a nationwide leader in
the management and marketing of CCPs, including fly ash used as a substitute for portland cement. Headwaters CCP business is comprised of a nationwide storage and distribution network and revenue is diversified geographically and by market.

In the energy segment, Headwaters is focused on reducing waste and increasing the value of energy-related feedstocks, primarily in the
areas of low-value coal and oil. In coal, Headwaters owns and operates several coal cleaning facilities that remove rock, dirt, and other impurities from waste coal, resulting in higher-value, marketable coal. Headwaters also licensed technology and
sold reagents to the coal-based solid alternative fuel industry through December 31, 2007. In oil, Headwaters believes that its heavy oil upgrading technology represents a substantial improvement over current refining technologies.
Headwaters heavy oil upgrading process uses a liquid catalyst precursor to generate a highly active molecular catalyst to convert residual oil feedstocks into higher-value distillates that can be refined into gasoline, diesel and other
products.

Basis of Presentation  Headwaters fiscal year ends on September 30 and unless otherwise noted, references
to 2007 refer to Headwaters fiscal quarter and/or six-month period ended March 31, 2007 and references to 2008 refer to Headwaters fiscal quarter and/or six-month period ended March 31, 2008. Other references to years refer to
Headwaters fiscal year rather than a calendar year. The consolidated financial statements include the accounts of Headwaters, all of its subsidiaries and other entities in which Headwaters has a controlling interest. All significant
intercompany transactions and accounts are eliminated in consolidation. Due to the seasonality of most of Headwaters operations and other factors, the consolidated results of operations for 2008 are not indicative of the results to be expected
for the full fiscal 2008 year.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with
the rules and regulations of the Securities and Exchange Commission (SEC) for quarterly reports on Form 10-Q. In the opinion of management, all adjustments considered necessary for a fair presentation have been included, and consist of normal
recurring adjustments. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted. These financial statements
should be read in conjunction with the consolidated financial statements and notes thereto included in Headwaters Annual Report on Form 10-K for the year ended September 30, 2007 (Form 10-K) and in Headwaters Quarterly Report on
Form 10-Q for the quarter ended December 31, 2007.

Recent Accounting Pronouncements  In September 2006, the Financial
Accounting Standards Board (FASB) issued SFAS No. 157, Fair Value Measurements which addresses how companies should measure fair value when they are required to use a fair value measure for recognition or disclosure purposes under
generally accepted accounting principles. Headwaters must adopt SFAS No. 157 no later than the first quarter of the fiscal year ending September 30, 2009. Headwaters uses fair value measurements to determine the reported amounts of assets
acquired and liabilities assumed in purchase transactions, in testing for potential goodwill impairment, for disclosure of the fair value of financial instruments, and elsewhere. It is therefore possible that the implementation of SFAS No. 157
could have a material effect on the reported amounts or disclosures in Headwaters consolidated financial statements in future periods.

In December 2007,
the FASB issued SFAS No. 141R, Business Combinations, and SFAS No. 160, Accounting and Reporting of Noncontrolling Interest in Consolidated Financial Statements, an Amendment of ARB No. 51. These new standards
will significantly change the accounting for and reporting of business combination transactions and minority interests in consolidated financial statements. Headwaters must adopt these standards simultaneously as of October 1, 2009, the
beginning of its fiscal 2010 year, which adoption will have a material effect on the accounting for any business combination consummated thereafter or any minority interest that exists at that time.

In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities, an Amendment of SFAS
No. 133. This new standard requires enhanced disclosures about how and why an entity uses derivative instruments, how such instruments and related hedged items are accounted for under SFAS No. 133, and how those instruments and items
affect an entitys financial position, financial performance, and cash flows. Headwaters must adopt SFAS No. 161 no later than October 1, 2009. Headwaters has entered into certain hedge transactions in the past, primarily to limit
variable interest rate exposure, but there are no such hedges outstanding as of March 31, 2008. Accordingly, the adoption of this standard could affect future disclosures related to any derivative instruments or related hedges that are entered
into in future periods.

Headwaters has reviewed all other recently issued accounting standards which have not yet been adopted in order to
determine their potential effect, if any, on the results of operations or financial position of Headwaters. Based on that review, Headwaters does not currently believe that any of these other recent accounting pronouncements will have a significant
effect on its current or future financial position, results of operations, cash flows or disclosures.

Reclassifications 
Certain prior period amounts have been reclassified to conform to the current periods presentation. The reclassifications had no effect on net income or total assets.



|2. | Segment Reporting
|-- | -----------------

Headwaters currently
operates three business segments: building products, CCPs and energy. These segments are managed and evaluated separately by management due to differences in their markets, operations, products and services. Revenues for the building products
segment consist of product sales to wholesale and retail distributors, contractors and other users of building products. CCP revenues consist primarily of product sales with a small amount of service revenue. Revenues for the energy segment through
December 31, 2007 consisted primarily of sales of chemical reagents and license fees related to our Section 45K business. Beginning January 1, 2008, revenues for this segment have consisted largely of coal sales. Future energy segment
revenues are currently expected to consist primarily of coal sales.

The following segment information has been prepared in accordance with
SFAS No. 131, Disclosure about Segments of an Enterprise and Related Information. Segment performance is evaluated primarily on revenue and operating income, although other factors are also used, such as income tax credits generated
by activities of the energy segment. Intersegment sales are immaterial.

Segment costs and expenses considered in deriving segment operating
income (loss) include cost of revenue, amortization, research and development, and segment-specific selling, general and administrative expenses. Amounts included in the Corporate column represent expenses not specifically attributable
to any segment and include administrative departmental costs and general corporate overhead. Segment assets reflect those specifically attributable to individual segments and primarily include accounts receivable, inventories, property, plant and
equipment, intangible assets and goodwill. Cash and cash equivalents and certain other assets are included in the Corporate column.

Senior Secured Credit Agreements  Headwaters senior secured credit facility
currently consists of a first lien term loan in the amount of $210.0 million, plus $15.0 million outstanding under the revolving credit arrangement. The credit facility provides for up to $60.0 million of borrowings under the revolving credit
arrangement, with the ability to increase this amount to $100.0 million, subject to obtaining additional revolving loan commitments. The first lien term loan is senior in priority to all other debt and is secured by all assets of Headwaters. The
terms of the credit facility, as currently amended, are described in more detail in the following paragraphs. Headwaters is in compliance with all debt covenants as of March 31, 2008.

The first lien term loan bears interest, at Headwaters option, at either i) the London Interbank Offered Rate (LIBOR) plus 2.0%, 2.25%, or 2.5%,
depending on the credit ratings that have been most recently announced for the loans by Standard & Poors Ratings Services (S&P) and Moodys Investors Service, Inc. (Moodys); or ii) the Base Rate plus 1.0%,
1.25%, or 1.5%, again depending on the credit ratings announced by S&P and Moodys. Base rate is defined as the higher of the rate announced by Morgan Stanley Senior Funding and the overnight rate charged by the Federal Reserve Bank of New
York plus 0.5%. Headwaters current rate is LIBOR plus 2.0%. Headwaters can lock in new LIBOR rates for the first lien term loan for one, two, three or six months. The weighted-average interest rate on the first lien term loan was approximately
4.6% at March 31, 2008. Interest on the first lien term loan is generally payable on a quarterly basis.

The first lien term loan is
repayable $84.8 million in February 2011 and $125.2 million in April 2011, the termination date. There are mandatory prepayments of the first lien term loan in the event of certain asset sales and debt and equity issuances and from excess cash
flow, as defined in the agreement. Optional prepayments of the first lien term loan are permitted without penalty or premium. Once repaid in full or in part, no reborrowings can be made.

Borrowings under
the revolving credit arrangement are generally subject to the terms of the first lien term loan agreement and bear interest at either LIBOR plus 1.75% to 2.5% (depending on Headwaters total leverage ratio, as defined), or the Base
Rate plus 0.75% to 1.5%. Borrowings and reborrowings of any available portion of the $60.0 million revolver can be made at any time through September 2009, when all loans must be repaid and the revolving credit arrangement terminates. The fees for
the unused portion of the revolving credit arrangement range from 0.5% to 0.75% (depending on Headwaters total leverage ratio, as defined). As of March 31, 2008, Headwaters had $15.0 million of borrowings outstanding under the
revolving credit arrangement, which amount was increased to $25.0 million subsequent to March 31, 2008, all of which has been classified as current because of the intent to repay the borrowings within 12 months. The credit agreement also allows
for the issuance of letters of credit, provided there is capacity under the revolving credit arrangement. As of March 31, 2008, stand-by letters of credit totaling approximately $9.4 million were outstanding, with expiration dates ranging from
June 2008 to September 2009.

The credit facility contains restrictions and covenants common to such agreements, including limitations on
the incurrence of additional debt, investments, merger and acquisition activity, asset sales and liens, annual capital expenditures in excess of $100.0 million annually, and the payment of dividends, among others. In addition, Headwaters must
maintain certain leverage and fixed charge coverage ratios, as those terms are defined in the agreements, as follows: i) a total leverage ratio of 3.75:1 or less, declining to 3.5:1 in 2010; ii) a maximum ratio of consolidated funded indebtedness
minus subordinated indebtedness to EBITDA of 2.75:1, declining to 2.5:1 in 2010; and iii) a minimum ratio of EBITDA plus rent payments for the four preceding fiscal quarters to scheduled payments of principal and interest on all indebtedness for the
next four fiscal quarters of 1.25:1.

2.875% Convertible Senior Subordinated Notes Due 2016  Headwaters has outstanding $172.5
million of 2.875% convertible senior subordinated notes due June 2016, with interest payable semi-annually. These notes are subordinate to the senior secured debt described above and rank equally with the 2.50% convertible senior subordinated notes
due 2014 described below, and any future senior subordinated debt. Holders of the notes may convert the notes into shares of Headwaters common stock at a conversion rate of 33.3333 shares per $1,000 principal amount ($30 conversion price), or
5.75 million aggregate shares of common stock, contingent upon certain events. The conversion rate adjusts for events related to Headwaters common stock, including common stock issued as a dividend, rights or warrants to purchase common
stock issued to all holders of Headwaters common stock, and other similar rights or events that apply to all holders of common stock.

The notes are convertible if any of the following five criteria are met: 1) satisfaction of a market price condition which becomes operative if, prior to June 1, 2011, in any calendar quarter the closing price of Headwaters
common stock exceeds $39 per share for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the calendar quarter, or, at any time on or after June 1, 2011 the closing price of Headwaters common
stock exceeds $39 per share; 2) a credit rating, if any, assigned to the notes is three or more rating subcategories below the initial rating; 3) the notes trade at less than 98% of the product of the common stock trading price and the number of
shares of common stock issuable upon conversion of $1,000 principal amount of the notes, except this provision is not available if the closing common stock price is between 100% and 130% of the current conversion price of the notes; 4) Headwaters
calls the notes for redemption; or 5) upon the occurrence of specified corporate transactions.

Headwaters may call the notes for redemption
at any time prior to June 4, 2011 if the closing common stock price exceeds 130% of the conversion price for 20 trading days in any consecutive 30-day trading period (in which case Headwaters must provide a make whole payment of the
present value of all remaining interest payments on the redeemed notes through June 1, 2011). Headwaters may redeem any portion of the notes at any time on or after June 4, 2011. In addition, the holder of the notes has the right to
require Headwaters to repurchase all or a portion of the notes on June 1, 2011 or if a fundamental change in common stock has occurred, including termination of trading. Subsequent to June 1, 2011, the notes require an additional interest
payment equal to 0.40% of the average trading price of the notes if the trading price equals 120% or more of the principal amount of the notes. Headwaters includes the additional shares of common stock contingently issuable under the convertible
notes in its diluted EPS calculations on an if-converted basis (see Note 8).

conversion price), subject to adjustment. Upon conversion, Headwaters will pay cash up to the principal amount of the notes, and shares of common stock to the extent the price of Headwaters common stock exceeds the conversion price during a
20-trading-day observation period. The conversion rate is adjusted for certain corporate transactions referred to as fundamental changes.

The notes are convertible at the option of the holder prior to December 1, 2013 if any of the following criteria are met: 1) during any fiscal quarter the closing price of Headwaters common stock exceeds
$38.32 per share for at least 20 trading days during a period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter; 2) during the five-business-day period after any ten-consecutive-trading-day period, the
notes trade at less than 98% of the product of the common stock trading price and the number of shares of common stock issuable upon conversion of $1,000 principal amount of the notes; or 3) upon the occurrence of specified corporate transactions.
The notes are convertible on or after December 1, 2013 regardless of the foregoing circumstances. Headwaters may not redeem the notes. If Headwaters has a fundamental change, holders may require Headwaters to repurchase the notes at
a price equal to the principal amount plus any accrued interest.

In connection with the issuance of the notes, Headwaters entered into
convertible note hedge and warrant transactions for the purpose of effectively increasing the common stock conversion price for the notes from $29.48 per share to $35.00 per share. The convertible note hedge terminates upon the maturity of the notes
or when none of the notes remain outstanding due to conversion or otherwise.

Interest  During the three months ended
March 31, 2007 and 2008, Headwaters incurred total interest costs of approximately $9.9 million and $6.6 million, respectively, including approximately $2.6 million and $0.7 million, respectively, of non-cash interest expense and approximately
$0.2 million in both periods of interest costs that were capitalized. During the six months ended March 31, 2007 and 2008, Headwaters incurred total interest costs of approximately $19.3 million and $13.4 million, respectively, including
approximately $3.3 million and $1.3 million, respectively, of non-cash interest expense and approximately $0.5 million and $0.4 million, respectively, of interest costs that were capitalized.

Interest income was approximately $0.6 million and $0.2 million during the three months ended March 31, 2007 and 2008, respectively, and $1.5 million
and $0.9 million during the six months ended March 31, 2007 and 2008, respectively. The weighted-average interest rate on the face amount of outstanding long-term debt, disregarding amortization of debt issue costs, was approximately 4.5% at
September 30, 2007 and 3.5% at March 31, 2008.



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

Headwaters estimated
effective income tax rate for the fiscal year ending September 30, 2008, exclusive of discrete items, is 29.0%, which rate was applied to income before income taxes for the six months ended March 31, 2008. Headwaters also recognized $3.0
million of net income tax expense in the six months ended March 31, 2008 for discrete items that did not affect the calculation of the estimated effective income tax rate for the 2008 fiscal year. The discrete items consisted primarily of
Section 45K-related changes in estimates pertaining to the nine-month period ended September 30, 2007, which in turn resulted from the phase-out of Section 45K tax credits for calendar 2007 being different than previously estimated.
In the six months ended March 31, 2007, Headwaters recognized a net $1.2 million income tax benefit for discrete items that did not affect the calculation of the estimated effective income tax rate for the 2007 fiscal year. After consideration
of the effect of the discrete items, income tax expense totaled approximately 86.4% of income before income taxes for the six months ended March 31, 2008, compared to 20.8% for the six months ended March 31, 2007. The income tax rates for
the three months ended March 31, 2007 and 2008 were 17.0% and 18.5%, respectively.

The estimated
effective tax rate for fiscal 2008, exclusive of the discrete items, is lower than the statutory rate primarily due to Section 45 refined coal tax credits (which are different from the Section 45K tax credits discussed elsewhere) related
to several coal cleaning facilities that Headwaters currently owns and operates as well as additional facilities that Headwaters expects to be operating later in fiscal 2008. Headwaters believes it is more likely than not the refined coal produced
at many of these facilities qualifies for tax credits pursuant to Section 45 of the Internal Revenue Code, notwithstanding the uncertainties and risks associated with the tax credits, as more fully described in Note 9. Excluding the effect of
all tax credits, Headwaters estimated effective tax rate for 2008 would have been approximately 39%.

The estimated effective tax rate
for fiscal 2007 was lower than the statutory rate primarily due to Section 45K tax credits related to two coal-based solid alternative fuel facilities that Headwaters owned and operated, plus Headwaters 19% interest in an entity that
owned and operated another alternative fuel facility (where Headwaters was not the primary beneficiary). The alternative fuel produced at these three facilities through December 2007 qualified for tax credits pursuant to Section 45K (formerly
Section 29) of the Internal Revenue Code, subject to the uncertainties and other risks associated with the tax credits, all as more fully described in Note 9.

In July 2006, the FASB issued Interpretation No. 48, Accounting for Uncertainty in Income Taxes  an Interpretation of FASB Statement No. 109 (FIN 48). This interpretation prescribes a
consistent financial reporting recognition threshold and measurement standard, as well as criteria for subsequently recognizing, derecognizing and measuring tax positions taken or expected to be taken in a tax return. FIN 48 also requires expanded
disclosures with respect to the uncertainty in income taxes. Headwaters adopted FIN 48 effective as of October 1, 2007, the beginning of the 2008 fiscal year, with a cumulative adjustment to decrease retained earnings and increase income tax
liabilities for unrecognized income tax benefits by $19.8 million, which included $2.9 million for interest and penalties. Certain reclassifications of deferred income taxes as of September 30, 2007 were also made to conform to the presentation
requirements of FIN 48, but these were not material. Headwaters recognizes accrued interest and potential penalties related to all income tax liabilities, including unrecognized income tax benefits, in income tax expense. During the six months ended
March 31, 2008, Headwaters recognized approximately $0.9 million of interest and penalties and as of March 31, 2008, there was approximately $7.6 million accrued for the payment of interest and penalties.

As of March 31, 2008, Headwaters had approximately $17.9 million of net unrecognized tax benefits, most of which are classified as a long-term
liability. Prior to the adoption of FIN 48, most unrecognized income tax benefits were classified as a current liability. Approximately $25.7 million of gross unrecognized income tax benefits would affect the 2008 effective tax rate if released into
income.

Headwaters is currently under audit by the IRS for fiscal years 2003 through 2006 and has open tax periods subject to examination
by both federal and state taxing authorities for fiscal years 2003 through 2007. It is reasonably possible that the amount of Headwaters unrecognized income tax benefits will significantly change within the next 12 months. These changes could
be the result of Headwaters ongoing tax audits or the settlement of outstanding audit issues. However, due to the number of years under audit and the matters being examined, at the current time, an estimate of the range of reasonably possible
outcomes cannot be made.

|9. | Commitments and Contingencies
|-- | -----------------------------

Significant
new commitments and ongoing contingencies as of March 31, 2008 not disclosed previously, are as follows.

Acquisitions 
During fiscal 2006 and 2007, Headwaters acquired certain assets and assumed certain liabilities of several privately-held companies in the building products industry. Pursuant to contractual terms for some of the acquisitions, additional amounts may
be payable in the future, based on the achievement of stipulated revenue or earnings targets for periods ending no later than March 2010.

For all acquisition transactions, assets acquired and liabilities assumed were recorded at their estimated fair values as of the acquisition dates. If any future earn-out consideration is paid for any acquisition, goodwill will be increased
accordingly.

Property, Plant and Equipment  As of March 31, 2008, Headwaters was committed to spend approximately $54.3
million on capital projects that were in various stages of completion.

Legal
Matters  Headwaters has ongoing litigation and asserted claims which have been incurred during the normal course of business, including the specific matters discussed below. Headwaters intends to vigorously defend or resolve these matters
by settlement, as appropriate. Management does not currently believe that the outcome of these matters will have a material adverse effect on Headwaters operations, cash flow or financial position.

Historically, costs paid to outside legal counsel for litigation have comprised a majority of Headwaters litigation-related costs. During the six
months ended March 31, 2008, Headwaters incurred approximately $1.0 million of expense for legal matters, which consisted primarily of costs for outside legal counsel. Headwaters currently believes the range of potential loss for all unresolved
matters, excluding costs for outside counsel, is from $1.1 million up to the amounts sought by claimants and has recorded a total liability as of March 31, 2008 of $1.1 million. Claims and damages sought by claimants in excess of this amount
are not deemed to be probable. Headwaters outside counsel currently believe that unfavorable outcomes of outstanding litigation are neither probable nor remote and declined to express opinions concerning the likely outcomes or liability to
Headwaters. It is not possible to estimate what litigation-related costs will be in future periods.

The matters discussed below raise
difficult and complex legal and factual issues, and the resolution of these issues is subject to many uncertainties, including the facts and circumstances of each case, the jurisdiction in which each case is brought, and the future decisions of
juries, judges, and arbitrators. Therefore, although management believes that the claims asserted against Headwaters in the named cases lack merit, there is a possibility of material losses in excess of the amounts accrued if one or more of the
cases were to be determined adversely against Headwaters for a substantial amount of the damages asserted. It is possible that a change in the estimates of probable liability could occur, and the changes could be material. Additionally, as with any
litigation, these proceedings require that Headwaters incur substantial costs, including attorneys fees, managerial time and other personnel resources, in pursuing resolution.

Boynton. In October 1998, Headwaters entered into a technology purchase agreement with James G. Davidson and Adtech, Inc. The transaction
transferred certain patent and royalty rights to Headwaters related to a synthetic fuel technology invented by Davidson. (This technology is distinct from the technology developed by Headwaters.) This action is factually related to an earlier action
brought by certain purported officers and directors of Adtech, Inc. That action was dismissed by the United States District Court for the Western District of Tennessee and the District Courts order of dismissal was affirmed on appeal. In the
current action, the allegations arise from the same facts, but the claims are asserted by certain purported stockholders of Adtech. In June 2002, Headwaters received a summons and complaint from the United States District Court for the Western
District of Tennessee alleging, among other things, fraud, conspiracy, constructive trust, conversion, patent infringement and interference with contract arising out of the 1998 technology purchase agreement entered into between Davidson and Adtech
on the one hand, and Headwaters on the other. The plaintiffs seek declaratory relief and compensatory damages in the approximate amount of $40.0 million and punitive damages. In February 2006, the District Court dismissed all claims against
Headwaters. Also in February 2006, plaintiffs filed an appeal. In July 2007, the United States Court of Appeals for the Federal Circuit vacated the dismissal in favor of Headwaters as to the civil conspiracy and constructive trust claims and
remanded the case to the District Court for further proceedings. Because the resolution of the litigation is uncertain, legal counsel cannot express an opinion as to the ultimate amount, if any, of Headwaters liability.

Headwaters Building Products Matters.There are litigation and pending and threatened claims made against certain subsidiaries of Headwaters
Construction Materials (HCM), a division within Headwaters building products segment, with respect to several types of exterior finish systems manufactured and sold by its subsidiaries for application by contractors on residential and
commercial buildings. Typically, litigation and these claims are defended by such subsidiaries insurance carriers. The plaintiffs or claimants in these matters have alleged that the structures have suffered damage from latent or progressive
water penetration due to some alleged failure of the building product or wall system. Some claims involve alleged defects associated with components of an Exterior Insulating and Finish System (EIFS) which was produced for a limited time (through
1997) by the HCM subsidiaries. There is a 10-year projected claim period following discontinuation of the product. Other claims involve alleged liabilities associated with certain stucco and architectural stone veneer products which are produced and
sold by certain subsidiaries of HCM.

Typically, the
claims cite damages for alleged personal injuries and punitive damages for alleged unfair business practices in addition to asserting more conventional damage claims for alleged economic loss and damage to property. To date, claims made against such
subsidiaries have been paid by their insurers, with the exception of minor deductibles or self-insured retentions, although such insurance carriers typically have issued reservation of rights letters. None of the cases has gone to trial.
While, to date, none of these proceedings have required that HCM incur substantial costs, there is no guarantee of insurance coverage or continuing coverage. These and future proceedings may result in substantial costs to HCM, including
attorneys fees, managerial time and other personnel resources and costs. Adverse resolution of these proceedings could have a materially negative effect on HCMs business, financial condition, and results of operation, and its ability to
meet its financial obligations. Although HCM carries general and product liability insurance, HCM cannot assure that such insurance coverage will remain available, that HCMs insurance carrier will remain viable, or that the insured amounts
will cover all future claims in excess of HCMs uninsured retention. Future rate increases may also make such insurance uneconomical for HCM to maintain. In addition, the insurance policies maintained by HCM exclude claims for damages resulting
from exterior insulating finish systems, or EIFS, that have manifested after March 2003. Because resolution of the litigation and claims is uncertain, legal counsel cannot express an opinion as to the ultimate amount, if any, of HCMs
liability.

Other. Headwaters and its subsidiaries are also involved in other legal proceedings that have arisen in the normal course
of business.

Section 45K Matters  A material amount of Headwaters consolidated revenue and net income has
historically been derived from license fees and sales of chemical reagents, both of which were dependent on the ability of licensees and other customers to manufacture and sell qualified synthetic fuel that generated tax credits under
Section 45K (formerly Section 29) of the Internal Revenue Code. Headwaters has also claimed Section 45K tax credits for synthetic fuel sales from facilities in which it owned an interest (see Note 7). The following issues exist
related to Section 45K tax credits.

Termination of Section 45K. By law, Section 45K tax credits for synthetic fuel
produced from coal have expired for synthetic fuel sold after December 31, 2007. With the expiration of Section 45K at the end of calendar 2007, Headwaters licensees synthetic fuel facilities and the facilities owned by Headwaters
have closed because production of synthetic fuel is not profitable absent the tax credits. The closure of these synfuel facilities has had and will continue to have a material adverse effect on the current and future revenue, net income and cash
flow of Headwaters.

Phase-Out. Section 45K tax credits were subject to phase-out after the average annual U.S. wellhead oil
price (reference price) reached a beginning phase-out threshold price, and would have been eliminated entirely if the reference price reached the full phase-out price. Recently, the calendar 2007 reference price and phase-out range was announced and
accordingly, Headwaters adjusted the previously recognized revenue and tax credits as required to reflect the finalized phase-out. The adjustments recorded in the quarter ended March 31, 2008 resulted in an increase of approximately $5.2
million to the license fee revenue that was previously recognized through December 31, 2007. The existence and unpredictability of phase-out has materially adversely affected both the amount and timing of recognition of Headwaters
revenue, net income and cash flow beginning in fiscal 2006 and continuing through March 31, 2008. At the current time, Headwaters does not believe there are any material residual contingencies related to phase-out.

IRS Audits. Licensees are subject to audit by the IRS. The IRS may challenge whether Headwaters licensees have satisfied the requirements of
Section 45K or applicable Private Letter Rulings, including placed-in-service requirements, or may attempt to disallow Section 45K tax credits for some other reason. The IRS has initiated audits of certain licensee-taxpayers who claimed
Section 45K tax credits and will continue the audit process in the future. To the extent not already paid to Headwaters, the inability of a licensee to claim Section 45K tax credits could reduce amounts to be received by Headwaters from
licensees for license fee revenue recognized prior to March 31, 2008. In addition, the IRS is currently auditing Headwaters tax credits claimed for synthetic fuel sold from the facilities in which it owns an interest. The tax credits
which are under audit that Headwaters believes are more likely than not to be sustained, and are therefore not included in unrecognized income tax benefits in the balance sheet, total approximately $30.0 million.

(Unaudited)

Section 45 Matters  As explained in Note 7, Headwaters estimated effective tax rate for fiscal 2008 is lower than the statutory rate due to refined coal tax credits related to several facilities that Headwaters
currently owns and operates as well as additional facilities that Headwaters expects to be operating later in fiscal 2008. Headwaters believes the refined coal produced or to be produced at many of these facilities and sold to qualified buyers will
qualify for tax credits under Section 45 (which is different from the Section 45K tax credit discussed in preceding paragraphs) of the Internal Revenue Code. To date, the IRS has issued limited public guidance about how this tax credit
program will be administered and the restrictions on the availability of such credits. Based on the language of Section 45, Headwaters believes that many of its coal cleaning facilities will be eligible for Section 45 refined coal tax
credits, and as a result, has recognized a benefit for such credits in its 2008 tax provision. The ability to claim tax credits is dependent upon a number of conditions, including, but not limited to:



| |  |  | Placing facilities in service on or before December 31, 2008;
| | - |  | -------------------------------------------------------------



| |  |  | Producing a fuel from coal that is lower in NOx and either SOx or mercury emissions by the specified amount as compared to the emissions of the feedstock;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Producing a fuel at least 50% more valuable than the feedstock; and
| | - |  | -------------------------------------------------------------------



| |  |  | Sale of the fuel to a third party for the purpose of producing steam.
| | - |  | ---------------------------------------------------------------------

The IRS may challenge Section 45 tax credits claimed by Headwaters on any one of these or other conditions. In addition, Congress may modify or
repeal Section 45 so that these tax credits may not be available in the future. If Headwaters is not able to claim Section 45 tax credits for fiscal 2008, this will materially adversely affect income tax expense and income taxes paid in
future periods.

|ITEM 2. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

The following discussion and analysis should be read in conjunction with the consolidated financial statements and related notes included in this Form
10-Q. Our fiscal year ends on September 30 and unless otherwise noted, references to 2007 refer to our fiscal quarter and/or six-month period ended March 31, 2007 and references to 2008 refer to our fiscal quarter and/or six-month period
ended March 31, 2008. Other references to years refer to our fiscal year rather than a calendar year.

Overview

Consolidation and Segments. The consolidated financial statements include the accounts of Headwaters, all of our subsidiaries, and other entities
in which we have a controlling interest. All significant intercompany transactions and accounts are eliminated in consolidation. We made one acquisition in 2007. This entitys results of operations for the period from the acquisition date
through March 31, 2008 have been consolidated with our results; its operations up to the date of acquisition have not been included in the consolidated results for any period.

We currently operate in three industries: building products, coal combustion products (CCPs) and energy. In the building products segment, we design,
manufacture, and sell architectural stone and resin-based exterior siding accessories (such as shutters, mounting blocks, and vents) and other products. Revenues consist of product sales to wholesale and retail distributors, contractors and other
users of building products. We are a nationwide leader in the management and marketing of CCPs. Revenues in the CCP segment consist primarily of fly ash, used as a substitute for portland cement, and other product sales. In the energy segment, we
are focused on reducing waste and increasing the value of energy-related feedstocks, primarily in the areas of low-value coal and oil. Revenues for the energy segment through December 31, 2007 consisted primarily of sales of chemical reagents
and license fees related to our Section 45K business. Beginning January 1, 2008, revenues for this segment have consisted largely of coal sales.

Operations and Strategy. During the past several years, we have executed our two-fold plan of maximizing cash flow from our existing operating business units and diversifying from significant reliance on the
legacy energy segment Section 45K (formerly Section 29) business. With the addition and expansion of our CCP management and marketing business through acquisitions in 2002 and in 2004, and the growth of our building products business
through several acquisitions in fiscal 2004, 2006 and 2007, we have achieved revenue growth and diversification in three business segments. Because we also incurred increased indebtedness to make strategic acquisitions, one of our ongoing financial
objectives has been to focus on increasing cash flows to reduce debt levels. In fiscal 2008, however, our primary use of cash is currently expected to consist of capital expenditures.

A material amount of our consolidated revenue and net income through December 31, 2007 was derived from license fees and sales of chemical reagents,
both of which were dependent on the ability of licensees and other customers to manufacture and sell qualified synthetic fuel that generated tax credits under Section 45K of the Internal Revenue Code. We have also claimed Section 45K tax
credits for synthetic fuel sales from facilities in which we owned an interest. The following issues exist related to Section 45K tax credits.

By law, Section 45K tax credits for synthetic fuel produced from coal have expired for synthetic fuel sold after December 31, 2007. With the expiration of Section 45K at the end of calendar 2007, our licensees synthetic
fuel facilities and the facilities we owned have closed because production of synthetic fuel is not profitable absent the tax credits. The closure of these synfuel facilities has had and will continue to have a material adverse effect on our current
and future revenue, net income and cash flow.

Section 45K tax credits were subject to phase-out after the average annual U.S.
wellhead oil price (reference price) reached a beginning phase-out threshold price, and would have been eliminated entirely if the reference price reached the full phase-out price. Recently, the calendar 2007 reference price and phase-out range was
announced and accordingly, we adjusted the previously recognized revenue and tax credits as required to reflect the finalized phase-out. The adjustments recorded in the quarter ended March 31, 2008 resulted in an increase of approximately $5.2
million to the license fee revenue that was previously recognized through December 31, 2007. The existence and unpredictability of phase-out has materially adversely affected both the amount and timing of recognition of our revenue, net income
and cash flow beginning in fiscal 2006 and continuing through March 31, 2008. At the current time, we do not believe there are any material residual contingencies related to phase-out.

We own and operate several new and recently-renovated coal cleaning facilities that remove rock, dirt, and other impurities from waste coal, resulting in
higher-value, marketable coal. In addition, we are currently constructing several additional coal cleaning facilities, which construction is currently expected to be our largest single investment of cash during fiscal 2008. The coal



19

##### Table of Contents

cleaning facilities are being financed with available cash and with lease financing. During the quarter ended March 31, 2008, coal sales were $6.2
million, compared to $1.4 million in the quarter ended December 31, 2007. We currently expect future energy segment revenue to primarily consist of coal sales.

Our CCPs business strategy is to continue to negotiate long-term contracts so that we can invest in transportation and storage infrastructure for the marketing and sale of CCPs. We are also continuing our efforts to
expand usage of high-value CCPs and to develop more uses for lower-value CCPs, such as blending. Our building products business has been significantly affected by the substantial downturn in residential construction and our current strategy is to
reduce operating costs as much as possible and be positively positioned to take advantage of an industry turnaround at some point in the future. Our CCPs and building products businesses are affected by seasonality, with the highest revenue and
profitability produced in the June and September quarters. In fiscal 2008, substantially all of our operating income is expected to be generated in these two quarters.

Our on-going acquisition strategy targets businesses that are leading companies in their respective industries and that enjoy healthy operating margins, thus providing additional cash flow that complements the
financial performance of our existing businesses. In 2006, we began to acquire small companies with innovative products that can be marketed using our existing distribution channels. We are also committed to continuing to invest in research and
development activities that are focused on energy-related technologies and nanotechnology. We participate in joint ventures that operate an ethanol plant located in North Dakota and a hydrogen peroxide plant in South Korea. We are also investing in
other energy projects such as the refining of heavy crude oils into lighter transportation fuels.

In 2005 and 2006, we focused on the
integration of our large 2004 acquisitions, including the marketing of diverse kinds of building products through our national distribution network. We became highly leveraged as a result of those acquisitions, but have reduced our outstanding debt
significantly since that time through cash generated from operations, from an underwritten public offering of common stock and from proceeds from settlement of litigation. We continue to focus on the early repayment of long-term debt, subject to
availability of cash.

Three Months Ended March 31, 2008 Compared to Three Months Ended March 31, 2007

The information set forth below compares our operating results for the quarter ended March 31, 2008 (2008) with operating results for the
quarter ended March 31, 2007 (2007).

Summary. Our total revenue for 2008 was $172.0 million, down 37% from $274.1 million for
2007. Gross profit decreased 56%, from $94.4 million in 2007 to $41.3 million in 2008. Operating income (loss) decreased from $45.4 million to a loss of $(8.9) million. Net income (loss) decreased from $27.2 million, with diluted earnings per share
of $0.59, to a loss of $(9.2) million, or $(0.22) per diluted share, in 2008.

Excluding our Section 45K business, total revenue for
2008 was $164.1 million, down 8% from $178.3 million for 2007. Gross profit excluding Section 45K was $33.9 million in 2008, down 22% from $43.3 million for 2007. Operating income (loss) changed from $(5.1) million to $(16.4) million in 2008.
Net income (loss) was $(13.4) million and diluted earnings (loss) per share was $(0.33), compared to a net loss of $(8.3) million, or $(0.17) per diluted share, in 2007.

Revenue and Gross Margins. The major components of revenue, along with gross margins, are discussed in the sections below.

Building Products Segment. Sales of building products during 2008 were $93.6 million with a corresponding direct cost of $72.8 million. Sales of building products during 2007 were $115.5 million with a
corresponding direct cost of $87.2 million. The decrease in sales of building products during 2008 is due primarily to the effects of the depressed residential housing and remodeling market which impacts sales across most of our product lines. We
believe our niche strategy and our focus on productivity improvements tempered somewhat the impact of the severe slow down in new residential construction on our revenue. The gross margin percentage declined from 2007 to 2008 due primarily to fixed
costs being absorbed by lower sales. Because a substantial amount of our revenues in this segment are dependent on the housing market, we anticipate continuing impact in fiscal 2008 and beyond from the current slowdown in the housing industry.

CCP Segment. CCP revenues for 2008 were $61.0 million with a corresponding direct cost of $47.7 million. CCP revenues for 2007 were
$62.1 million with a corresponding direct cost of $46.8 million. The decrease in CCP revenues and gross margin percentage was due primarily to wet weather conditions in certain markets and a change in sales mix among regions and products.

Energy Segment. In 2007, our energy segment revenue consisted almost exclusively of chemical reagent sales, license fee revenue
related to our solid alternative fuel technologies, and to a lesser extent, sales of synthetic fuel, all of which related to our Section 45K business. In 2008, our energy segment revenue consisted primarily of residual Section 45K revenue,
recognized in 2008 due to finalization in 2008 of the calendar 2007 phase-out, along with $6.2 million of coal sales. Coal sales revenue in 2007 was less than $0.1 million. Future energy segment revenues are currently expected to consist primarily
of coal sales.

##### Table of Contents

Operating Expenses. The decrease in amortization expense of $0.4 million from 2007 to 2008 was due
primarily to intangible assets that have been fully amortized. Research and development expense decreased by $1.5 million from 2007 to 2008 primarily because of decreased spending on our coal-to-liquids technologies. Selling, general and
administrative expenses increased $3.2 million, or 8%, to $41.0 million for 2008 from $37.8 million for 2007. The increase in 2008 was due primarily to $3.8 million of restructuring costs related to plant consolidations and other cost improvement
projects undertaken in our building products segment during 2008.

Other Income and Expense. During 2008, we reported net other
expense of $2.4 million compared to net other expense of $12.7 million during 2007. The decrease in net other expense of $10.3 million was comprised of a decrease in net interest expense of approximately $2.9 million and a net change in other
income/expense items of approximately $7.4 million.

Net interest expense decreased from $9.1 million in 2007 to $6.2 million in 2008, due
to lower variable interest rates and lower average levels of long-term debt in 2008 as compared to 2007. We currently expect interest expense in fiscal 2008 to be less than the fiscal 2007 amount.

The change in other income/expense items of $7.4 million consisted primarily of $3.6 million of gain on the sale of property, plant and equipment in 2008
compared to a gain of $0.4 million in 2007, plus a $4.0 million decrease in costs related to our investment in the coal-based solid alternative fuel production facility described in Note 7 to the consolidated financial statements. The majority of
the property, plant and equipment sold in 2008 represented non-strategic assets in our building products segment. A portion of the proceeds from this sale were used to acquire assets that have increased the capacity of our Texas-based concrete block
business, enabling us to meet current and projected demand in this line of business.

Income Tax Provision. The recorded income tax
rates for 2008 and 2007 were 19% and 17%, respectively, including discrete items of $1.2 million (expense) in 2008 and $2.2 million (benefit) in 2007. The discrete items consisted primarily of Section 45K-related changes in estimates pertaining
to periods prior to the beginning of each respective fiscal year. The estimated effective tax rates, excluding discrete items, were 29% for fiscal 2008 and 23% for fiscal 2007, which rates were applied to fiscal year-to-date income before income
taxes, prior to adjusting for discrete items.

The estimated effective tax rate for fiscal 2008, exclusive of discrete items, is lower than
the statutory rate primarily due to Section 45 refined coal tax credits (which are different from the Section 45K tax credits discussed elsewhere) related to several coal cleaning facilities that we currently own and operate as well as
additional facilities that we expect to be operating later in fiscal 2008. We believe it is more likely than not the refined coal produced at many of these facilities qualifies for tax credits pursuant to Section 45 of the Internal Revenue
Code, notwithstanding the uncertainties and risks associated with the tax credits, as more fully described in Note 9 to the consolidated financial statements. Excluding the effect of all tax credits, our estimated effective tax rate for 2008 would
have been approximately 39%.

The estimated effective tax rate for fiscal 2007 was lower than the statutory rate primarily due to
Section 45K tax credits related to two coal-based solid alternative fuel facilities that we owned and operated, plus our 19% interest in an entity that owned and operated another alternative fuel facility (where we were not the primary
beneficiary). The alternative fuel produced at these three facilities through December 2007 qualified for tax credits pursuant to Section 45K (formerly Section 29) of the Internal Revenue Code, subject to the uncertainties and other risks
associated with the tax credits, all as more fully described in Note 9.

Future changes to our estimates of fiscal 2008 Section 45
refined coal tax credits could be material to our future 2008 income tax expense. Also, we are currently under audit by the IRS for fiscal years 2003 through 2006 and have open tax periods subject to examination by both federal and state taxing
authorities for fiscal years 2003 through 2007. It is reasonably possible that the amount of unrecognized income tax benefits will significantly change within the next 12 months. These changes could be the result of the ongoing tax audits or the
settlement of outstanding audit issues. However, due to the number of years under audit and the matters being examined, at the current time, an estimate of the range of reasonably possible outcomes cannot be made.

Six Months Ended March 31, 2008 Compared to Six Months Ended March 31, 2007

The information set forth below compares our operating results for the six months ended March 31, 2008 (2008) with operating results for the six
months ended March 31, 2007 (2007).

##### Table of Contents

Summary. Our total revenue for 2008 was $420.9 million, down 23% from $549.0 million for 2007.
Gross profit decreased 40%, from $174.5 million in 2007 to $104.4 million in 2008. Operating income decreased from $79.3 million to $9.5 million. Net income decreased from $44.2 million, with diluted earnings per share of $0.96, to $0.7 million, or
$0.02 per diluted share, in 2008.

Excluding our Section 45K business, total revenue for 2008 was $358.6 million, down 3% from $371.5
million for 2007. Gross profit excluding Section 45K was $85.0 million in 2008, down 10% from $94.4 million for 2007. Operating income (loss) changed from $0.3 million to a loss of $(9.9) million in 2008. Net income (loss) was $(9.9) million
and diluted earnings (loss) per share was $(0.23), compared to a net loss of $(9.8) million, or $(0.20) per diluted share, in 2007.

Revenue and Gross Margins. The major components of revenue, along with gross margins, are discussed in the sections below.

Building Products Segment. Sales of building products during 2008 were $208.3 million with a corresponding direct cost of $154.7 million. Sales of building products during 2007 were $238.3 million with a corresponding direct cost of
$177.7 million. The decrease in sales of building products during 2008 was due primarily to the effects of the depressed residential housing and remodeling market which impacted sales across most of our product lines. We believe our niche strategy
and our focus on productivity improvements tempered somewhat the impact of the severe slow down in new residential construction on our revenue and mitigated the effect on our gross margins.

CCP Segment. CCP revenues for 2008 were $138.4 million with a corresponding direct cost of $103.6 million. CCP revenues for 2007 were $131.3
million with a corresponding direct cost of $96.2 million. The increase in CCP revenues was due primarily to upward pricing trends in several markets, despite some challenging weather conditions in certain areas. The gross margin percentage
decreased from 2007 to 2008 primarily due to increased costs for material and higher transportation costs.

Energy Segment. In 2007,
our energy segment revenue consisted almost exclusively of chemical reagent sales, license fee revenue related to our solid alternative fuel technologies, and to a lesser extent, sales of synthetic fuel, all of which related to our Section 45K
business. In 2008, more than 84% of our energy segment revenue consisted of Section 45K revenue, the substantial majority of which was recognized in the quarter ended December 31, 2007, the expiration date of Section 45K tax credits.
Coal sales revenue was $7.6 million in 2008, compared to less than $0.2 million in 2007.

Operating Expenses. The decrease in
amortization expense of $0.7 million from 2007 to 2008 was due primarily to intangible assets that have been fully amortized. Research and development expense decreased by $1.2 million from 2007 to 2008 primarily because of decreased spending on our
coal-to-liquids technologies. Selling, general and administrative expenses increased $1.6 million, or 2%, to $76.0 million for 2008 from $74.3 million for 2007. The increase in 2008 was due primarily to $3.8 million of restructuring costs related to
plant consolidations and other cost improvement projects undertaken in our building products segment during 2008, partially offset by decreased costs in marketing and various other business unit expenses.

Other Income and Expense. During 2008, we reported net other expense of $4.3 million compared to net other expense of $23.5 million during 2007.
The decrease in net other expense of $19.2 million was comprised of a decrease in net interest expense of approximately $5.3 million and a net change in other income/expense items of approximately $13.9 million.

Net interest expense decreased from $17.3 million in 2007 to $12.0 million in 2008, due to lower variable interest rates and lower average levels of
long-term debt in 2008 as compared to 2007.

The change in other income/expense items of $13.9 million consisted primarily of $8.0 million
of gain on the sale of property, plant and equipment in 2008 compared to a gain of $0.2 million in 2007, plus a $6.3 million decrease in costs related to our investment in the coal-based solid alternative fuel production facility described in Note 7
to the consolidated financial statements. The majority of the property, plant and equipment sold in 2008 represented non-strategic assets in our building products segment. A portion of the proceeds from this sale were used to acquire assets that
have increased the capacity of our Texas-based concrete block business.

Income Tax Provision. The recorded income tax rates for
2008 and 2007 were 86% and 21%, respectively, including discrete items of $3.0 million (expense) in 2008 and $1.2 million (benefit) in 2007. The discrete items consisted primarily of Section 45K-related adjustments pertaining to periods prior
to the beginning of each respective fiscal year. The estimated effective tax rates, excluding discrete items, were 29% for fiscal 2008 and 23% for fiscal 2007, which rates were applied to income before income taxes, prior to adjusting for discrete
items.

Impact of Inflation and Related Matters

Our operations have been impacted by increased cement, polypropylene and poly-vinyl chloride costs in the building products segment and increased fuel
costs that have affected transportation costs in most of our business units. The increased costs of polypropylene, poly-vinyl chloride and fuel have been caused in part by the increase in prices of petroleum-based materials and by supply and demand.
The increased costs of cement appear to be caused by supply and demand and by transportation costs.

We have been successful in passing on
some, but not all, of the increased material and transportation costs to customers. It is not possible to predict the future trend of material and transportation costs, nor our ability to pass on any future price increases to customers.

Liquidity and Capital Resources

Summary of
Cash Flow Activities. Net cash provided by operating activities for the six months ended March 31, 2008 (2008) was $22.4 million compared to $41.6 million for the six months ended March 31, 2007 (2007). In both 2008 and 2007, the
primary investing activities consisted of the purchase of property, plant and equipment and payments for acquisitions. In 2008, financing activities consisted primarily of an increase in long-term debt, primarily as a result of increased capital
expenditures, and treasury stock purchases. In 2007, our primary financing activities consisted of the issuance of convertible debt and the repayment of senior debt with the proceeds. More details about our investing and financing activities are
provided in the following paragraphs.

Investing Activities. Total expenditures for property, plant and equipment in 2008 were $56.9
million, an increase of $31.4 million over 2007. The largest share of capital expenditures in both periods was incurred by the building products segment; however, in 2008, a much higher proportion of total capital expenditures was incurred by the
energy segment, as compared to 2007. A significant portion of our 2008 and planned future capital expenditures (which for fiscal 2008 are currently expected to exceed the fiscal 2007 year amount) represent expansion of operations, rather than
maintenance of operating capacity, primarily due to growth initiatives in the energy segment, particularly the construction of coal cleaning facilities.

Capital expenditures are limited by our senior debt covenants to $100.0 million annually; however, the prior fiscal year unused amount of annual capital expenditures limit can be carried forward and used in the
subsequent fiscal year. As of March 31, 2008, we had approximately $45.0 million of unused amounts of capital expenditures from the prior fiscal year and we were committed to spend approximately $54.3 million on capital projects that were in
various stages of completion, primarily in the energy segment. In 2008, we realized $12.9 million of proceeds from the sale of property, plant and equipment, most of which represented non-strategic assets in our building products segment. A portion
of the proceeds from this sale were used to acquire assets that increased the capacity of our Texas-based concrete block business, enabling us to meet current and projected demand in this line of business.

In 2007, we acquired 100% of the ownership interests of a privately-held company in the building products business. Total consideration paid at the date
of acquisition of approximately $53.0 million consisted primarily of cash. An additional amount, $19.0 million, was paid in 2008, based on earnings of the acquired entity for the 12-month period ended September 30, 2007 that exceeded an
agreed-upon threshold. Pursuant to contractual terms for some of the acquisitions made in prior years, additional amounts may be payable in the future, based on the achievement of stipulated revenue or earnings targets for periods ending no later
than March 2010. If future earn-out consideration is paid in excess of amounts accrued for any acquisition, goodwill will be increased accordingly.

We are required to periodically test for goodwill impairment, at least annually, or sooner if evidence of possible impairment arises. We perform our annual impairment testing using a test date of June 30. If the residential housing and
remodeling market continues to be depressed, there is risk that one or more of our reporting units may fail the SFAS No. 142 goodwill impairment test, requiring a write-down of goodwill. We expect to complete the goodwill impairment testing in
the quarter ending September 30, 2008, with any necessary non-cash impairment charges recorded in that quarter.

We intend to continue
to expand our business through growth of existing operations, commercialization of technologies currently being developed, and possible strategic acquisitions of products or entities that expand our current operating platform. Acquisitions have
historically been an important part of our long-term business strategy. We routinely review potential acquisitions, including those in the areas of building products, CCP marketing, and coal and catalyst technologies. It is possible that some
portion of future cash and cash equivalents and/or proceeds from the issuance of stock or debt could be used to fund acquisitions of complementary businesses in the chemical, CCP, energy, building products and related industries; however, because of
cash flow considerations and current events affecting the debt and equity markets, we do not currently anticipate any significant acquisitions in fiscal 2008 or early 2009. Our senior secured credit agreement limits acquisitions in the aggregate to
$50.0 million of cash consideration and $20.0 million of non-cash consideration annually, with no more than $30.0 million of cash consideration for any

##### Table of Contents

one acquisition, unless our total leverage ratio, as defined, is less than or equal to 3.50:1.0, after giving effect to an acquisition, in which
case the foregoing limitations do not apply. The senior secured credit agreement also limits the amount we can invest in joint ventures and other less than 100%-owned entities.

We have invested in several joint ventures which are accounted for using the equity method of accounting, but do not currently have plans to
significantly increase our investments in those entities.

Financing Activities. In 2008, we had net proceeds of $18.9 million from
the issuance of long-term debt, most of which represented a $15.0 million draw-down of our senior revolving credit facility, which amount was increased to $25.0 million subsequent to March 31, 2008. With the exception of draw-downs of the
senior revolving credit facility and minor amounts of other long-term debt, we have no long-term debt repayments that are due prior to 2011. In 2008, we made treasury stock purchases totaling $14.8 million, near the limit established by our senior
secured credit agreement. Accordingly, we do not currently have plans for any future treasury stock purchases.

In 2007, financing
activities consisted of the repayment of long-term debt and, as described in more detail in Note 6 to the consolidated financial statements, the issuance of $160.0 million of 2.50% convertible senior subordinated notes due February 2014. The net
proceeds and additional cash on hand were used to repay senior debt and the remaining balance of outstanding notes payable to a bank. We may, in the future, make optional prepayments of senior debt depending on actual cash flows, our current and
expected cash requirements and other applicable factors we deem to be significant.

Due to covenants associated with our senior debt, we
currently have restrictions on our ability to obtain significant additional amounts of long-term debt. However, we have historically experienced strong positive cash flow from operations which has enabled us to repay a substantial amount of our
long-term debt prior to scheduled maturities. While we expect our positive cash flow to continue in the future, our positive cash flow from operations is expected to be lower in fiscal 2008 and subsequent years due to the termination of our
Section 45K business, as described previously and in Note 9 to the consolidated financial statements. Also, while we have periodically accessed the debt and equity markets in prior years, affordable and available additional debt and equity may
be more difficult for us to obtain in future periods than in the past, due to less favorable market conditions as well as changes in our business model.

Reference is made to Note 6 to the consolidated financial statements for detailed information about our outstanding long-term debt and compliance with debt covenants, as well as the available $60.0 million revolving
credit arrangement. Subject to obtaining additional revolving loan commitments, we can increase the revolving credit limit to $100.0 million. The senior credit facility contains restrictions and covenants common to such agreements, including
limitations on the incurrence of additional debt, investments, merger and acquisition activity, asset sales and liens, annual capital expenditures in excess of $100.0 million annually, and the payment of dividends, among others. In addition, we must
maintain certain leverage and fixed charge coverage ratios. We are in compliance with all debt covenants as of March 31, 2008.

In
January 2007, we announced that we were planning an exchange offer for our 2.875% convertible senior subordinated notes due 2016, whereby new notes with similar, but not identical, terms, along with an exchange fee, would be issued upon tender of
the existing notes. In April 2007, we announced that the commencement of an exchange offer had been indefinitely postponed. We continue to evaluate the merits and timing of an exchange offer.

In both 2007 and 2008, cash proceeds from the exercise of options and employee stock purchases were not material. Option exercise activity is primarily
dependent on our stock price and is not predictable. To the extent non-qualified stock options are exercised, or there are disqualifying dispositions of shares obtained upon the exercise of incentive stock options, we receive an income tax deduction
generally equal to the income recognized by the optionee. Such amounts were not material in either 2007 or 2008.

Working Capital.
As of March 31, 2008, our working capital was $130.2 million. Notwithstanding the expiration of Section 45K tax credits as of December 31, 2007 and the resulting impact on cash flow, we currently expect operations to produce positive
cash flow in future periods and believe working capital, along with available borrowings under the revolving credit arrangement, will be sufficient for operating needs for the next 12 months.

Income Taxes. Historically, our cash requirements for income taxes generally approximated the income tax provision; however, there is usually some
lag in paying estimated taxes during a fiscal year due to the seasonality of our operations and because estimated income tax payments are typically based on annualizing the fiscal years income based on year-to-date results. There has also been
some lag in realizing cash benefits from the utilization of tax credits due to the interaction of our September 30 fiscal year end and the different fiscal year ends of the entities through which we have received the tax credits. Since fiscal
2006 and continuing through March 31, 2008, there has been more variability in the relationship between the income tax provision and income tax payments because the tax provision calculation has been materially dependent upon the estimated
phase-out percentage of Section 45K tax credits (see Notes 7 and 9 to the consolidated financial statements).

##### Table of Contents

As discussed previously, cash payments for income taxes are reduced for tax deductions resulting from
disqualifying dispositions of incentive stock options and from the exercise of non-qualified stock options, which amount was not material in 2007 or 2008. Option exercise activity is primarily dependent on our stock price which is not predictable,
and likewise, it is not possible to estimate what tax benefits may be realized from future option exercises.

Summary of Future Cash
Requirements. Significant future cash uses, in addition to operational working capital requirements, including income tax payments and interest payments on long-term debt, are currently expected to consist primarily of capital expenditures.

Legal Matters

We have ongoing
litigation and asserted claims which have been incurred during the normal course of business. Reference is made to Note 9 to the consolidated financial statements for a description of our accounting for legal costs and for other information about
legal matters.

Recent Accounting Pronouncements

Reference is made to Note 1 to the consolidated financial statements for a discussion of accounting pronouncements that have been recently issued which we have not yet adopted.



|ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|------- | ----------------------------------------------------------

We are exposed to financial market risks, primarily related to changes in interest rates and certain foreign currencies. We do not use derivative financial instruments for speculative or trading purposes. We have entered into certain hedge
transactions in the past, primarily to limit our variable interest rate exposure, but there are no such hedges outstanding as of March 31, 2008. The Blue Flint joint venture has hedges in place related to variable interest rates and
commodities.

As described in more detail in Note 6 to the consolidated financial statements, our senior debt, which totaled $225.0 million
as of March 31, 2008 and $235.0 million subsequent to March 31, 2008, bears interest at a variable-rate. Accordingly, assuming no change in the amount of senior debt outstanding, a change in the interest rate of 1% would change our
interest expense by approximately $2.3 million during the 12 months ending March 31, 2009.

We have limited operations in foreign
jurisdictions. However, one of our joint ventures with Evonik Industries AG owns a hydrogen peroxide business located in South Korea. This joint venture has over  25.0 million of long-term debt and other obligations denominated in Euros.
Because the debt and other obligations are payable in a currency different from the Korean Won, the joint ventures functional currency, it must be translated into Korean Won at the end of each reporting period based on current exchange rates.
As a result of this requirement, the joint venture is subject to foreign currency exchange rate movements. During the six months ended March 31, 2008 the joint venture recorded a foreign currency exchange loss of $4.7 million which was included
in our results of operations. A change in the relationship between the Euro and Korean Won of 10% would result in a gain or loss of approximately $2.0 million for us.



|ITEM 4. | CONTROLS AND PROCEDURES
|------- | -----------------------

Disclosure Controls and
Procedures  We maintain disclosure controls and procedures that are designed to ensure that information we are required to disclose in the reports that we file or submit under the Securities Exchange Act of 1934 (the Exchange Act), such as
this Quarterly Report on Form 10-Q, is recorded, processed, summarized and reported within the time periods specified by SEC rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure
that information we are required to disclose in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including the Chief Executive Officer (CEO) and the Chief Financial Officer (CFO), to allow
timely decisions regarding required disclosure.

Our management evaluated, with the participation of our CEO and CFO, the effectiveness of
our disclosure controls and procedures as of March 31, 2008, pursuant to paragraph (b) of Rules 13a-15 and 15d-15 under the Exchange Act. This evaluation included a review of the controls objectives and design, the operation of the
controls, and the effect of the controls on the information presented in this Quarterly Report. Our management, including the CEO and CFO, do not expect that disclosure controls can or will prevent or detect all errors and all fraud, if any. A
control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Our disclosure controls and procedures are designed to provide such reasonable
assurance of achieving their objectives. Also, the projection of any evaluation of the disclosure controls and procedures to future periods is subject to the risk that the disclosure controls and procedures may become inadequate because of changes
in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

##### Table of Contents

Based on their review and evaluation, and subject to the inherent limitations described above, our CEO
and CFO have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective as of March 31, 2008 at the above-described reasonable assurance level.

Internal Control over Financial Reporting  Management is responsible for establishing and maintaining adequate internal control over
financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation
of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.

Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even internal controls determined to be effective can provide only reasonable assurance with respect to financial
statement preparation and presentation. The effectiveness of our internal control over financial reporting is subject to various inherent limitations, including cost limitations, judgments used in decision making, assumptions about the likelihood of
future events, the possibility of human error, and the risk of fraud. The projection of any evaluation of effectiveness to future periods is subject to the risk that controls may become inadequate because of changes in conditions, or that the degree
of compliance with policies may deteriorate. Because of these limitations, there can be no assurance that any system of internal control over financial reporting will be successful in preventing all errors or fraud or in making all material
information known in a timely manner to the appropriate levels of management.

There has been no change in our internal control over
financial reporting during the quarter ended March 31, 2008 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
