PART I



|ITEM 1. | BUSINESS
|------- | --------

General Development of Business

Headwaters Incorporated (Headwaters) is a diversified company providing products, technologies and services in three industries: construction
materials, coal combustion products (CCPs) and alternative energy. Headwaters uses technology to differentiate itself from competitors and to create value in its businesses.

In the construction materials segment, Headwaters designs, manufactures, and sells architectural stone and resin-based exterior siding accessories (such
as window shutters) and other products. Headwaters believes that many of its branded products have a leading market position. Revenue from Headwaters construction materials 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 believes it is uniquely positioned to manufacture an array of building materials that use fly ash, such as block, stucco, and mortar.
Headwaters CCP business is comprised of a nationwide storage and distribution network and revenue is diversified geographically and by market.

In the alternative energy segment, Headwaters is focused on reducing waste and increasing the value of energy 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 or other low-value coal, resulting in higher-value, marketable coal. Headwaters also licenses technology and sells reagents to the coal-based solid alternative fuel
industry. 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.

Headwaters Company History. Headwaters is incorporated in Delaware. Headwaters stock trades under the New York Stock Exchange symbol HW.

As used herein, Headwaters, combined company, we, our and us refer to Headwaters Incorporated
and its consolidated subsidiaries, including Headwaters Energy Services Corp. and its subsidiaries; Headwaters Resources, Inc. and its subsidiaries; Headwaters Construction Materials, Inc. and its subsidiaries (including Eldorado Stone LLC and Tapco
International Corporation and their subsidiaries and affiliates); Headwaters Heavy Oil, LLC; and Headwaters Technology Innovation, LLC; unless the context otherwise requires. As used in this report, HES refers to Headwaters Energy
Services Corp., together with its consolidated subsidiaries and affiliates; HRI refers to Headwaters Resources, Inc. and its consolidated subsidiaries; HCM refers to Headwaters Construction Materials, Inc., together with its
consolidated subsidiaries and affiliates (including Eldorado, which refers to Eldorado Stone LLC and its subsidiaries and affiliates; and Tapco, which refers to Tapco International Corporation and its subsidiaries); and
HTI refers to Headwaters Technology Innovation Group, Inc. unless the context otherwise requires.

Construction Materials

Headwaters Construction Materials (HCM) produces construction materials that minimize waste, conserve natural resources, and/or use less
energy in manufacturing or application. We operate leading businesses in manufactured architectural stone products and siding accessories (such as window shutters, gable vents, mounting blocks, simulated wood shake siding and composite roofing) and
professional tools used in exterior residential remodeling and construction. We plan to expand the business organically and through small

##### Table of Contents

strategic acquisitions. Our manufactured stone and building accessories products have a national presence in commercial, residential and remodeling markets.
HCM is also a leading supplier of concrete blocks and specialty blocks in Texas. We believe our traditional building products and new product offerings position HCM to participate in significant growth after the end of the current downturn in
residential construction. We participate in two segments within the siding industry, manufactured stone and specialty siding, both of which we believe have growth potential in periods when the residential construction market improves. The
construction markets are seasonal and the majority of our construction materials sales are in the residential construction market, which tends to slow down in the winter months.

Principal Products and their Markets

Manufactured Stone. Under the Eldorado Stone®, StoneCraft, and Dutch Quality Stone brands, we offer a wide variety of high-quality, hand-made manufactured stone products to meet a variety of design needs. Our manufactured architectural stone siding incorporates
several key features important to a successful siding product, including: high aesthetic quality, ease of installation, durability, low maintenance, reasonable cost and widespread availability. The Eldorado Stone product line has been designed and
is manufactured to be one of the most realistic architectural stone products in the world. Headwaters architectural stone siding is a lightweight, adhered siding product used by national, regional and local architectural firms, real estate
developers, contractors, builders and homeowners. Our stone products are used in construction projects ranging from large-scale residential housing developments and commercial projects to do-it-yourself home improvement jobs. In addition to its use
as a primary siding material, the Eldorado Stone product line is used in a variety of external and internal home applications such as walls, archways, fireplaces and landscaping. In 2006, we introduced an architectural brick veneer product.
Headwaters believes that our focus on product quality, breadth and innovation, combined with a geographically diversified manufacturing platform, provides us with significant marketing advantages over traditional materials such as natural stone,
brick or stucco.

Exterior Siding Accessories. We are a leading designer, manufacturer and marketer of resin-based siding
accessories and professional tools used in exterior residential home improvement and construction under the Tapco brands. These products, which are either injection-molded or extruded, enhance the appearance of homes and include decorative window
shutters, gable vents, and mounting blocks for exterior fixtures, roof ventilation, window and door trim products, specialty siding products, synthetic roofing tiles, and window well systems. Professional tools include portable cutting and shaping
tools used by contractors, on-site, to fabricate customized aluminum shapes that complement the installation of exterior siding.

Brands
include Tapco Integrated Tool Systems, Mid-America Siding Components, Builders Edge, Atlantic Premium Shutters, Vantage, The Foundry, InSpire, and
WellCraft. We market our injection-molded building product accessories to retailers and mass merchandisers through our Builders Edge and Vantage brands and to the manufactured housing market through the MHP brand. In addition, we market
tools through the Tapco brand, functional shutters and storm protection systems through the Atlantic Premium Shutters brand, specialty siding product through the Foundry brand, specialty roofing products through the InSpire brand, and window wells
under the WellCraft brand.

These building products serve the needs of the siding, roofing, and window and door installation industries.
Our injection-molded products are designed to enhance the exterior appearance of the home while delivering durability at a lower cost compared to similar aluminum, wood and plastic products while the functional shutters enhance the exterior
appearance of the home and can be manufactured to meet certain hurricane codes.

Concrete Block.We are one of the largest manufacturers and sellers of concrete block in the Texas market, one of Americas largest block markets. Fly ash is used in the manufacturing process for concrete block, brick and
foundation blocks. We also market mortar and stucco under the Best Masonry and Magna Wall® brands.

Flexcrete. HCM, in conjunction with the CCP group, is commercializing a new commercial and residential building product called Flexcrete. FlexCrete is an aerated concrete product with approximately 50%
fly ash

content. We expect FlexCrete will offer advantages for construction, including ease of use, physical strength, durability, energy efficiency, fire resistance
and environmental sensitivity.

Manufacturing

Headwaters architectural stone brands are currently manufactured through a network of eight plants strategically situated in proximity to customers. These locations allow for a high level of customer service,
shorter lead times and lower freight costs. We also have a production contract with a facility in Tijuana, Mexico.

We conduct
manufacturing, distribution and sales operations for resin-based accessories and ancillary products through eight facilities, which total approximately 985,000 square feet. Manufacturing assets include more than 100 injection molding presses, almost
all of which are automated through robotics or conveyor systems which has reduced cycle times and helped reduce waste. Any nonconforming plastic parts are reused as raw material, further minimizing waste.

We operate three of the most modern concrete block and brick manufacturing facilities in the industry. Our block and brick operations are located to
provide coverage of all the key metropolitan areas in Texas.

Distribution

Architectural stone is distributed throughout the United States and Canada primarily on a wholesale basis through a network of distributors, including
masonry and stone suppliers, roofing and siding materials distributors, fireplace suppliers and other contractor specialty stores. Distribution for Eldorado Stone branded products is conducted at its manufacturing facilities and at three
distribution centers.

Resin-based accessories and our ancillary products are distributed throughout the United States and Canada through
four primary distribution channels: one-step distributors that sell directly to contractors, two-step distributors that sell our products to lumberyards and one-step distributors, retail home centers/mass merchandisers, and manufactured housing.

We seek to be a leader in each meaningful distribution channel for our products by providing the broadest selection coupled with high
levels of customer service.

Sales and Marketing

We have a small direct sales force for architectural stone products. This sales force works closely with architects and contractors to provide information concerning the attributes and ease of installation of its
manufactured product and to promote market acceptance over traditional building materials.

Our resin-based products sales and
marketing organization supports the one-step, two-step distribution, and retail channels through various networks of sales support that include almost 180 independent sales representatives and a small group of business development managers, regional
sales managers and sales executives.

We maintain relationships with local contractors, professional builders, and other end-users by
participating in over 2,000 local shows and seven national shows annually. Local shows, sponsored by local distributors, enable us to promote our products through hands-on comparisons to competing products. These shows enable us to receive useful
feedback from local contractors, which leads to new product ideas, as well as significant goodwill within the trade.

Major Customers

We have a large customer base for our construction products. Because primarily all of the one-and two-step distributors have multiple
locations and each individual location generally has autonomy to stock various



5

##### Table of Contents

products from different suppliers, the number of ship-to locations is a better measure of the breadth of sales than is the total number of customers. In the
residential home improvement and building products market, we have approximately 6,900 non-retail ship-to locations and approximately 8,900 retail ship-to locations for our products. Sales are broadly diversified across customers and ship-to
locations. For fiscal 2007, three large customers together represented approximately 29% of total sales of our resin-based accessory products. None of our other construction materials lines had a customer representing over 10% of its product sales.

Sources of Available Raw Materials

We purchase cement, sand and aggregates as primary raw materials for our concrete-based products. We do not have long-term contracts for the supply of these materials. Worldwide demand for these materials has risen in
recent years, as well as our costs to purchase raw materials. However, we have not suffered from any long-term shortages and believe that supplies will be adequate in the future.

The raw materials purchased for resin-based products include polypropylene and styrene pellets, and PVC. Polypropylene and styrene are purchased
primarily from single (separate) suppliers. From time to time, prices for some of the raw materials used in production/assembly processes fluctuate significantly. Although we do not have any contracts with suppliers and purchase supplies on a
purchase order basis, we occasionally make volume purchases of materials to lock in pricing.

Coal Combustion Products

Principal Products and their Markets

We sell coal combustion products (CCPs), such as fly ash and bottom ash, which are created when coal is burned. CCPs have traditionally been an environmental and economic burden for power generators but, when properly managed,
can be valuable products. We supply CCPs as a replacement for portland cement in a variety of concrete infrastructure projects and building products. We are currently the largest manager and marketer of CCPs in the United States and also manage and
market CCPs in Canada and Puerto Rico. We have a number of long-term exclusive management contracts with coal-fueled electric generating utilities throughout the United States and provide CCP management services at more than 110 locations.

Utilities produce CCPs year-round, including in the winter when demand for electricity increases in many regions. In comparison, sales of
CCPs and construction materials produced using CCPs are keyed to construction market demands that tend to follow national trends in construction with predictable increases during temperate seasons. CCPs must be stored, usually in terminals, during
the off-peak sales periods as well as transported to where they are needed for use in construction. In part because of the cost of transportation, the market for CCPs used in construction is generally regional, although we ship products significant
distances to states such as California and Florida that have limited coal-fueled electric utilities producing high quality CCPs. We enjoy advantages in both logistics and sales from our status as the largest manager and marketer of CCPs in the
United States. We maintain 26 stand-alone CCP distribution terminals across North America, as well as approximately 100 plant-site supply facilities. We own or lease approximately 1,670 rail cars and more than 200 trucks, and also contract with
other carriers so that we can meet our transportation needs for the marketing and disposal of CCPs. In addition, we have more than 50 area managers and technical sales representatives nationwide to manage CCP customer relations.

The benefits of CCP use in construction applications include improved product performance, cost savings and positive environmental impact. Fly ash
improves both the chemical and physical performance of concrete, decreasing permeability and enhancing durability. When fly ash is used in concrete it also provides environmental benefits. In addition to conserving landfill space, fly ash usage
conserves energy and reduces green house gas emissions. According to the U.S. Environmental Protection Agency (EPA), one ton of fly ash used as a replacement for portland cement eliminates approximately one ton of carbon dioxide emissions associated
with cement production. The value of utilizing fly ash in concrete has been recognized by numerous

##### Table of Contents

federal agencies, including the United States Department of Energy (DOE) and the EPA, which has issued comprehensive procurement guidelines directing federal
agencies to utilize fly ash. The EPA has also created the Coal Combustion Products Partnership (C2P2) to promote national CCP utilization. Almost all states specify or recommend the use of fly ash in state and federal transportation
projects.

Higher-quality fly ash and other high-value CCPs have the greatest value because of the wide variety of higher-margin commercial
uses. The quality of fly ash produced by the combustion process at coal-fueled facilities varies widely and is affected by the type of coal feedstock used and the boilers maintained by the utilities. We assist our utility clients in their efforts to
improve the production of high-value CCPs at their facilities. A quality control system ensures that customers have a specific quality of CCPs for various applications while our investment in transportation equipment and terminal facilities provides
reliability of supply.

Sales and Marketing

We support our CCP marketing and sales program by focusing on customer desires for quality and reliability. Marketing efforts emphasize the performance value of CCPs, as well as the attendant environmental benefits.
We undertake a variety of marketing activities to increase fly ash sales. These activities include professional outreach, technical publications, relationships with industry organizations, and involvement in legislative initiatives leading to
greater use of CCPs. In addition, we have developed several specialty products that increase market penetration of CCPs and name recognition for our products for road bases, structural fills, industrial fillers and agricultural applications.

New Technologies for CCP Utilization. In an effort to maximize the percentage of CCPs marketed to end users and to minimize the
amount of materials disposed of in landfills, our research and development activities focus on expanding the use of CCPs by developing new products that utilize high volumes of CCPs. For example, through these research and development activities, we
developed two products to utilize the fly ash generated at fluidized bed combustion (FBC) power plants, which is generally unsuitable for use in traditional concrete applications. Stabil-Mix, a mixture of fly ash and lime used primarily for roadbed
stabilization, can be custom blended for optimum results in varying soil conditions. Pozzalime takes advantage of the lower SO3 and free lime content of some sources of FBC ash to create a product ideally suited for use as a cement replacement in
the manufacture of concrete masonry units.

Technologies to Improve Fly Ash Quality. We have also developed technologies that
maintain or improve the quality of CCPs, further expanding and enhancing their marketability. Utilities are switching fuel sources, changing boiler operations and introducing activated carbon and ammonia into the exhaust gas stream in an effort to
decrease costs and/or to meet increasingly stringent emissions control regulations. All of these factors can have a negative effect on fly ash quality, including an increase in the amount of unburned carbon in fly ash and the presence of ammonia
slip. We are attempting to address these challenges with the development and/or commercialization of two technologies: carbon fixation, which pre-treats unburned carbon particles in fly ash in order to minimize the particles adverse effects,
and ammonia slip mitigation, which counteracts the impact of ammonia contaminants in fly ash.

Sources of Available Raw Materials

Coal is the largest indigenous fossil fuel resource in the United States. The DOE estimates that in 2006 annual coal production was in
excess of 1.11 billion tons. About 92% of all coal consumed in the United States was for electrical power generation. The DOE further estimates that 2006 U.S. coal consumption for electrical power generation was slightly more than one billion tons.
Coal serves as a primary resource for baseline electricity production in the United States and is used to produce approximately half of the electricity generated in the United States. The combustion of coal results in a high percentage of residual
materials which serve as the raw material for the CCP industry. According to the American Coal Ash Association, in 2006, about

##### Table of Contents

54.2 million tons of CCPs were beneficially used in the United States of the approximately 124.8 million tons generated. This provides for
opportunities for continuing increases in CCP utilization. As long as a significant amount of electricity in this country is generated from coal-fueled generation, we believe that there will be significant supplies of CCP raw materials. However, as
Clean Air Act rules are implemented, the efforts of coal-fueled electric power producers to comply with tighter emissions requirements may have an adverse effect on supplies of fly ash suitable for use as a substitute for portland cement (see
Regulation).

Alternative Energy

In alternative energy, Headwaters is focused on reducing waste and increasing the value of energy feedstocks, primarily in the areas of low-value coal and oil. Headwaters Energy Services Corp. (HES) uses coal cleaning processes
that upgrade low value or waste coal by separating ash from the carbon. The resultant coal product is lower in ash, including sulfur, mercury and other impurities, and higher in Btu value. We also develop and commercialize technologies to convert or
upgrade fossil fuels into higher-value products, including direct coal liquefaction, the conversion of gas-to-liquid fuels, and heavy oil upgrading. Additionally, HES owns 51% and operates a 50 million gallon per year corn-to-ethanol facility
near Underwood, North Dakota.

The legacy business of HES, ending as of January 2008, has been, we believe, the market leader in enhancing
the value of coal used in power generation through licensing technologies and selling chemical reagents that convert coal into a solid alternative fuel. This solid alternative fuel has qualified for tax credits under Section 45K of the Internal
Revenue Code based upon the Btu content of the alternative fuel produced and sold. The sale of qualified alternative fuel has enabled facility owners who comply with certain statutory and regulatory requirements to claim federal tax credits under
Section 45K, which expires on December 31, 2007.

Principal Products and their Markets

We own and develop coal cleaning facilities. We are currently operating three coal cleaning facilities and nine additional coal cleaning facilities are in
various stages of acquisition, planning, development, and construction. We estimate that we have access to 240 million tons of waste and low value coal material which we have access to under contract in various coal regions around the country.
We are actively negotiating for the rights to process another 335 million tons. These facilities will provide HES with an opportunity to reduce sulfur oxides (SOx), nitrogen oxides (NOx) and mercury emissions from coal, greatly increasing
coals cleanliness and usability. The cleaned coal product is comparable to high value run of mine coal products. The cleaned coal is expected to be sold primarily to electric power plants, but can also be sold to other industrial users of
coal, and in certain cases, as a metallurgical grade coal to coke producers. We anticipate that the sale of the cleaned coal product will generate a refined coal tax credit for Headwaters under section 45 of the Internal Revenue Code in
circumstances where the requirements of section 45 can be met. To date, sales of the cleaned coal product have been modest, but are expected to increase substantially in 2008 as additional production facilities begin operation.

In 2006 Headwaters entered into a joint venture with Great River Energy (GRE) of Elk River, Minnesota to develop and construct a
50 million gallon-per-year ethanol production facility. The joint venture is named Blue Flint Ethanol, LLC and is owned 51% by HES and 49% by GRE (however both partners have equal voting rights and control over the joint venture). The Blue
Flint production facility is located at the GRE Coal Creek pulverized coal electric power station near Underwood, North Dakota. Coal Creek station supplies steam, water and other services to Blue Flint. HES operates the facility. The facility began
ethanol production in February 2007. Blue Flint purchases corn as the primary feedstock for the operation and sells ethanol and distillers grain products. Blue Flint customers use ethanol as a blending feedstock for gasoline and
distillers grain as feed for livestock.

HES began its business with the development and commercialization of technologies that
interact with coal-based feedstocks to produce a solid alternative fuel intended to be eligible for Section 45K (formerly Section 29)

tax credits. Since the tax credits will expire at the end of 2007 and have been subject to phase out as a result of higher oil prices (see Risk
Factors), our strategy has been to develop new alternative fuel business by taking advantage of our expertise.

New Business
Opportunities

As part of our alternative energy strategy, we are developing the following businesses and technologies:

Heavy Oil Upgrading Technology. We hold an exclusive, worldwide license to develop, market
and sublicense a unique heavy oil upgrading technology for the catalytic hydrocracking of heavy residual oils such as petroleum vacuum residue (so-called bottom of the barrel) and tar sand bitumen into lighter, more valuable petroleum
materials. The proprietary HCAT process uses a highly active, molecular-scale catalyst to efficiently convert heavy oils, including the asphaltenic components, which are generally considered the most difficult to process. In early 2006, we
announced the completion of the first commercial scale demonstration of the heavy oil upgrading technology at a large commercial refinery. Later in 2006, we completed a second refinery test of this technology. In 2007 we signed an agreement to sell
the HCAT catalyst precursor material and license the associated process to a petroleum refiner, subject to the successful completion of its own commercial trial. In 2008, we plan to continue discussions with operators of several heavy oil upgrading
facilities (in the U.S. and overseas) to explore how the addition of this technology to their existing refineries could increase product yields and reduce downtime caused by equipment fouling with minimal modifications to the existing facilities.

Hydrogen Peroxide. In September 2004, we entered into a joint venture with
Evonik Industries (formerly Degussa AG), located in Essen, Germany, to develop and commercialize a process for the direct synthesis of hydrogen peroxide, or H2O2. The venture aims to develop or invest in large facilities to produce low-cost hydrogen peroxide for chemical intermediates. High-volume
producers will be able to use the H2O2from these facilities
to produce intermediates such as propylene oxide (PO). Subject to terms and conditions of the agreement, the joint venture is responsible for development of manufacturing facilities. In October 2005, the joint venture announced the success of pilot
plant operations. In October 2007, a demonstration plant in Germany was completed and began startup operations. Demonstration plant operations are anticipated to be completed in early 2008. This demonstration plant is intended to provide performance
data relative to large scale operations, a prerequisite for engineering a commercial scale H2O2project. In September 2006, we and Evonik acquired a hydrogen peroxide plant in Korea to provide hydrogen peroxide to SKC Chemicals for use in the manufacture of PO. The joint venture plans to
expand the Korea facility to ultimately demonstrate the direct synthesis of hydrogen peroxide technology on a commercial scale. The joint venture is developing plans and exploring markets to build additional hydrogen peroxide production facilities
in other strategic locations to help meet the expected world-wide growth in demand for H2O2as a chemical intermediate.

Coal
Liquefaction. We have technologies for producing liquid fuels from coal. One of these technologies was evaluated during 2005 in a commercial pre-feasibility study commissioned by Oil India Limited, a Government of India enterprise. In October
2007 Headwaters announced that Oil India has begun a 16 month second phase of its feasibility analysis. Oil India is a public sector company engaged in energy services in the Assam Region of northeastern India, an area rich in natural resources but
distant from established oil refining operations. HES believes that its direct coal liquefaction (DCL) technology may assist Oil India in converting the Assam regions abundant and soluble coal into transportation fuels. The
technology involved encompasses some of the same elements that the Shenhua Group, Chinas largest coal company, licensed from an HES affiliate in 2004 for a DCL project in Majiata, China. We have entered into agreements with the government of
the Philippines and with a private company in China, for feasibility and pilot plant studies related to site-specific applications of our coal-to-liquids technologies.

In 2007 HES announced a joint venture with Great River Energy (GRE) and The North American Coal Corporation (NAC) to investigate the potential and to perform a pre-feasibility study for a coal-to-liquid plant located
at the NAC Falkirk Coal Company near Underwood, North Dakota. The partners have formed American

Lignite Energy (ALE) to pursue this project. Matching funds from the state of North Dakota in the amount of $10 million dollars have been secured by ALE. Up
to $1.7 million may be used by ALE in the performance of the pre-feasibility work for the project. The remaining funds may be used to pursue project engineering should a decision be made to continue work following a positive economic evaluation in
the first quarter of 2008 calendar year.

Section 45K Business

The HES legacy business of licensing technologies and selling chemical reagents to produce solid alternative fuel from coal ends as of December 31,
2007. Our approximately 35 licensees and customers have included electric utility companies, coal companies, financial institutions and other major businesses in the United States. License agreements have provided a quarterly earned royalty fee
generally set at a prescribed dollar amount per ton or a percentage of the tax credits earned by the licensee, in addition to sales revenues from proprietary latex-based chemicals manufactured and drop shipped for us by Dow Reichhold Specialty Latex
LLC. Our licensees and customers have obtained raw coal supplies for processing at their facilities and have in turn sold the alternative fuel produced to end users, primarily coal-fueled electricity generating facilities. License agreements have a
term ending as of January 1, 2008, the date on and after which tax credits may not be claimed under Section 45K.

During 2006,
industry production of solid alternative fuel was severely curtailed or stopped during the months of highest oil prices as facility owners evaluated the effect of oil prices on the statutory phase-out of Section 45K tax credits. Some producers
have indicated that they will cease production in the last calendar quarter of 2007 because of high oil prices. Most producers hedged against high oil prices for 2007, permitting continued production even in periods of high oil prices.

Segments and Major Customers

Headwaters
operates in three business segments, construction materials, CCPs and alternative energy. Additional information about segments is presented in Note 3 to the consolidated financial statements. No customer accounted for more than 10% of total revenue
from 2005 through 2007.

Research and Development

Headwaters maintains a staff of engineers, scientists and technicians at HTI with expertise in the design and operation of high-pressure and temperature process plants at its Lawrenceville, New Jersey pilot plant and
laboratory facilities. Among other technologies under development, we have the capability to work at the molecular level in the composition, aligning, spacing and adhering of nano-sized crystals of precious and transition metals on substrate
materials. The net effect is higher performance with lower precious metal content, nearly 100% selectivity for certain chemical reactions (i.e., the desired reaction is maximized with byproducts and waste minimized), long life and custom designed
nanocatalysts. Potential applications for this nanotechnology include new processes to improve existing catalysts for chemical and refining processes. Applications under pilot scale development include a naphtha reforming catalyst for gasoline
blending and synthetic fibers and plastics.

We are also conducting laboratory testing on the application of the technology to volatile
organic compound oxidation, high performance catalysts for fuel cells, and production of nanomaterials and nanofillers such as carbon nanospheres. We do not necessarily plan to commercially produce all of these products in their highly competitive
and regulated industries but we are exploring partnerships to develop, manufacture and market nanocatalysts and other products.

The
following table presents Headwaters approximate research and development expenses for the past three years.

Competition

Each of our business units experiences competition. Many of our competitors have greater financial, management and other resources and may be able to take advantage of acquisitions and other opportunities more readily.

Construction Materials.Notwithstanding our national position as a leading producer of manufactured architectural stone, we face significant
competition from other national and regional producers of similar products, and in particular from Owens Corning. Our primary competition for resin-based products includes Alcoa and Pinckney in the accessories market, and CertainTeed and Nailite in
the specialty siding market. HCM has competition from a number of larger manufacturers of mortars, stuccos and concrete masonry units. With respect to concrete masonry units, national and regional competition includes Oldcastle, Featherlite and
Pavestone.

CCPs. The business of marketing traditional CCPs is intensely competitive. HRI has substantial competition in two main
areas: obtaining CCP management contracts with utility and other industrial companies and marketing CCPs and related industrial materials. HRI has a presence in every region in the United States but, because the market for the management of CCPs is
highly fragmented and because the costs of transportation are high relative to sales prices, most of the competition in the CCP management industry is regional. There are many local, regional and national companies that compete for market share in
these areas with similar products and with numerous other substitute products. Although HRI has a number of long-term CCP management contracts with its clients, some of these contracts allow for the termination of the contract at the convenience of
the utility company upon a minimum 90-day notice. Moreover, certain of HRIs most significant regional CCP competitors appear to be seeking a broader national presence. These competitors include Lafarge North America Inc., Boral Material
Technologies Inc. and Cemex. Construction materials are produced and sold regionally by the numerous owners and operators of concrete ready-mix plants. Producers with sand and gravel sources near growing metropolitan areas have important
transportation advantages.

Alternative Fuels.With respect to its coal cleaning activities, HES faces competition from numerous
operators of run-of-mine coal preparation facilities, some of which also co-produce product from waste / low value coal streams. Our coal-based solid alternative fuel business also competes with other technology providers, manufacturers of chemical
reagents, as well as traditional coal and fuel suppliers. Further, many industrial coal users are limited in the amount of cleaned coal and alternative fuel product they can purchase from HES or its licensees because they have committed to purchase
a substantial portion of their coal requirements through long-term contracts for run-of-mine coal. Our Blue Flint ethanol plant will experience significant competition from many producers of ethanol and other biofuels throughout the United States.

Our heavy oil upgrading, coal liquefaction and catalyst technologies also experience competition from many of the worlds major
petroleum, chemical and energy companies. Those companies are actively engaged in research and development activities and have greater financial, management and other resources than we have.

Positive and Negative Factors. There are positive and negative factors pertaining to our competitive position.

Construction Materials.We have developed a recognized name in the manufactured architectural stone industry and a strong market share. Our
products have excellent authenticity and broad selection alternatives. Our architectural stone business has a limited, albeit growing, distribution network, strong competition from regional producers that do not have long shipping routes and
financial limitations that may not be shared by its largest national competitor. We have a leading market position in our siding accessories business because of our strong ability to manufacture and distribute a broad range of products economically
and rapidly. However, our resin-based siding accessory business strong market position suggests that its future growth will come largely from finding new products to put into its manufacturing and distribution channels, not from increasing
market share in the siding accessories industry. Our block and bagged products business is not national in breadth, although the



11

##### Table of Contents

block business enjoys a strong regional market position in Texas. Where its market strength is limited, the bagged products businesses do not have strong
economies of scale or price leadership, and have only limited product brand strength.

CCPs.Headwaters competitive position
has positive factors of a leading market position and long-term contracts. In addition, we have built a nationwide CCP distribution system not enjoyed by our competition. However, our CCP business is sometimes adversely affected by inclement weather
slowing concrete construction, the largest market for CCPs. We also face increasingly aggressive competition in marketing and sales of CCPs.

Alternative Energy.We believe HES is emerging as a leader in upgrading waste and other low value coal into usable feedstock for the steam coal market. However, we will have competition from other coal producers, including
traditional run-of-mine suppliers that are well financed and more experienced. HES enjoys the benefits of a leading market position in its Section 45K licensing and reagent sales businesses, although Section 45K tax credits will expire at
the end of calendar 2007. From a broader alternative fuel industry perspective, HES suffers from greater dependence on United States tax policy and administration than some competitors in coal supply and alternative fuels.

Our Blue Flint ethanol facility is a low-cost producer of ethanol due to its unique process configuration. Nevertheless, we produce a small fraction of
the total ethanol produced in the U.S., with additional producers completing new facilities each year.

Most of our business units are
experiencing greater competition for key raw materials including cement, aggregates, styrene, polypropylene and latex. This competition has contributed to shortages and price increases for raw materials used by us.

Intellectual Property

Headwaters has approximately
170 U.S. and foreign counterpart patents and approximately 294 U.S. and foreign counterpart patents pending. Additionally, Headwaters has approximately 134 U.S. and foreign trademarks and 128 U.S. and foreign trademark applications pending.

Collectively, the intellectual property is important to us, although there is no single patent or trademark that is itself material to us
at the present time.

There can be no assurance as to the scope of protection afforded by the patents. In addition, there are other
technologies in use and others may subsequently be developed, which do not, or will not, utilize processes covered by the patents. There can be no assurance that our patents will not be infringed or challenged by other parties or that we will not
infringe on patents held by other parties. Because many of these patents represent new technology, the importance of the patents to our business will depend on our ability to commercialize these technologies successfully, as well as our ability to
protect our technology from infringement or challenge by other parties.

In addition to patent protection, we also rely on trade secrets,
know-how and confidentiality agreements to protect technologies. Despite these safeguards, such methods may not afford complete protection and there can be no assurance that others will not either independently develop such know-how or unlawfully
obtain access to Headwaters know-how, concepts, ideas, and documentation. Since our proprietary information is important to our business, failure to protect ownership of our proprietary information would likely have a material adverse effect
on us.

Regulation

Environmental. Our operations and those of our suppliers and customers involved in coal-based energy generation, primarily utilities, are subject to federal, state and local environmental regulation. Our coal-based



12



---

##### Table of Contents

operations and those of our licensees are subject to federal, state and local environmental regulations that impose limitations on the discharge of
pollutants into the air and water and establish standards for the treatment, storage and disposal of waste products, which add to the cost of doing business and expose us to potential fines for non-compliance. Moreover, in order to establish and
operate the coal cleaning and synthetic fuel plants, power plants and operations to collect and transport CCPs and bottom ash, we and our licensees and customers have obtained various state and local permits and must comply with processes and
procedures that have been approved by regulatory authorities. Compliance with permits, regulations and the approved processes and procedures help protect against pollution and contamination and are critical to our business. Any failure to comply
could result in the issuance of substantial fines and penalties and cause us to incur environmental liabilities.

We believe that all
required permits to construct and operate coal cleaning and solid alternative fuel facilities have been or will be obtained and believe the facilities are in substantial compliance with all relevant laws and regulations governing alternative fuel
and coal cleaning operations.

In spite of safeguards, our operations entail risks of regulatory noncompliance or accidental discharge that
could create an environmental liability because hazardous materials are used or stored during normal business operations. For example, we use and share other hazardous chemicals in order to conduct operations involving distillation to purify
products, analysis, packaging of chemicals and the selling, warehousing and manufacturing of organic chemicals in small research volumes. We also use facilities to perform research and development activities involving coal, oil, chemicals and
industrial gases such as hydrogen. As a result, petroleum and other hazardous materials have been and are present in and on their properties. We generally hire independent contractors to transport and dispose of any hazardous materials generated and
send any hazardous wastes only to federally approved, large scale and reputable off-site waste facilities.

Our CCP business is dependent upon the recovery and processing of CCPs from our customers, typically coal-burning power plants. These entities are highly regulated under federal and state law, including the federal
Clean Air Act of 1970 and subsequent amendments, particularly the Clean Air Act Amendments of 1990, and corresponding state laws and EPA rules, which regulate the emissions of materials, such as SOxand NOx, into the air. The coal industry is directly affected by Clean Air Act permitting requirements and/or
emissions control requirements, including requirements relating to particulate matter, such as fugitive dust. The EPA has adopted National Ambient Air Quality Standards, or NAAQS, for particulate matter and ozone, and states will ultimately be
required to revise their existing state implementation plans to attain and maintain compliance with the NAAQS. Because electric utilities emit NOx, a precursor to ozone and particulate matter, our utility customers are likely to be affected when the
NAAQS are implemented by the states.

In addition, the 1990 Clean Air
Act Amendments require a study of utility power plant emissions of certain toxic substances, including mercury, and direct the EPA to regulate emissions of these substances, if warranted. In 2005, the EPA published (1) a finding determining not
to regulate electric utility steam generating units under the hazardous air pollutants provisions; (2) the final Clean Air Mercury Rule, for reducing mercury emissions from new or reconstructed coal-burning power plants; and (3) the Clean
Air Interstate Rule, which would require coal-burning power plants to upgrade their facilities to reduce emissions of sulfur dioxide and NOxand which, the
EPA determined, would also contribute to reduction of mercury emissions as a co-benefit. Taken together, these rules, if they are implemented in their current form, could result in reduced use of coal if utilities switch to other sources of fuel.
However, these rulemakings are currently being challenged in litigation. In light of the ongoing litigation, one or more of these rules ultimately may be revised in ways that cannot presently be anticipated.

Coal-fueled boilers have been impacted by regulations under the 1990 Clean Air Act Amendments,
which established specific emissions levels for SOxand NOxin order to reduce acid rain. These emissions levels have required utilities to undertake many of the following changes: change their fuel source(s), add scrubbers to capture SOx, add new boiler burner systems to control NOx, add or modify fuel pulverizers/air handling systems to control NOx, introduce flue gas conditioning materials to control particulate emissions in conjunction with

##### Table of Contents

meeting SOxemissions targets and in some very isolated cases
shut down a plant. All of these requirements can impact the quantity and quality of CCPs produced at a power plant, can add to the costs of operating a power plant and, depending on the requirements of individual state implementation plans, could
make coal a less attractive fuel alternative in the planning and building of utility power plants in the future. Furthermore, the Clean Air Mercury Rule could result in implementation of additional technologies at power plants that could negatively
affect fly ash quality. For example, activated carbon may be injected into power plant exhaust gas to capture mercury emissions. If carbon is collected with the fly ash as a result of this emissions treatment process, it may make the fly ash
undesirable for concrete. Carbon removal processes are technically challenging and expensive.

In 2007, the United States Supreme Court found that the EPA has authority under the Clean Air Act to regulate greenhouse gases that can contribute to global climate change, and that carbon dioxide qualifies as an
air pollutant as defined in that Act. This decision may lead to EPA establishment of a national ambient air quality standard for CO2. In
addition, the widespread interest in greenhouse gases and climate change could separately lead to other EPA or state regulation of CO2or other greenhouse
gases, including EPA regulation under the new source performance standards or through major source construction and operating permits. These developments may lead to further regulation of coal-fired boilers to reduce emissions of greenhouse gases,
with unknown impacts on the availability of CCPs.

In an effort to
stimulate the use of clean coal, the Energy Policy Act of 2005 provides funding for the deployment of clean coal technologies. The Act requires the Secretary of Energy to establish periodic milestones for funded projects, by the year 2020, to remove
at least 97% of sulfur dioxide; to emit no more than .08 lbs of NOxper million Btu; to achieve at least 90% reductions in mercury emissions; and to
achieve a thermal efficiency of at least 43% for coal of more than 9,000 Btu, 41% for coal of 7,000-9,000 Btu; and 39% for coal of less than 7,000 Btu.

Inappropriate use of CCPs can result in faulty end products. In some cases the products marketed by HRI consist of a mixture of client-supplied materials, including CCPs. HRI does not in all cases control the quality
of the final end product, but may share such control with the manufacturer of the ingredient materials. Therefore, there is a risk of liability regarding the quality of the materials and end products marketed by HRI. In cases where HRI is
responsible for end-product quality, such as a structural fill (where material is used to fill a cavity or designated area), HRI depends solely on its own quality assurance program.

Materials sold by HRI vary in chemical composition. Fossil fuel combustion wastes have been excluded from regulation as hazardous wastes
under subtitle C of the Resource Conservation and Recovery Act. However, EPA has determined that national regulations under subtitle D of the Resource Conservation and Recovery Act dealing with state and regional solid waste plans are warranted for
coal combustion byproducts disposed of in landfills or surface impoundments, or used to fill surface or underground mines. Although the EPA previously announced plans to publish proposed rules for CCPs generated by commercial electric power
producers in May 2007, EPA has now delayed that action to an unspecified future date, and issued a notice of data availability in August 2007 to obtain comments on the development of future regulations. In addition, the Office of Surface Mining
Reclamation and Enforcement is planning to revise its regulations to provide for the placement of coal combustion byproducts as part of surface coal mining and reclamation operations permitted under title V of the Surface Mining Control and
Reclamation Act. These proposed rules could make coal burning more expensive or less attractive to HRIs utility clients. HRI manages a number of landfill and pond operations that may be affected by EPAs proposed regulations. In most of
these operations the permitting is contractually retained by the client and the client would be liable for any costs associated with new permitting requirements. The effect of such regulations on HRI cannot be completely ascertained at this time.

Headwaters CCP business is engaged in providing services at one landfill operation that is permitted and managed as a hazardous
waste landfill. We provide the services necessary to landfill the clients hazardous wastes and operate certain in-plant equipment and systems for the client.

CCPs may contain small concentrations of metals that are considered as hazardous substances
under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). Land application of CCPs is regulated by a variety of federal and state statutes, which impose testing and management requirements to ensure environmental
protection. Under limited circumstances, mismanagement of CCPs can give rise to CERCLA liability.

A number of agencies are studying the
issue of nanotechnology, including the National Toxicology Program, the National Institute for Safety and Health, and the EPA. Many of these efforts are being coordinated through the interagency Nanoscale Science, Engineering and Technology
subcommittee of the White House Office of Science and Technology Policy, National Science and Technology Council. Nanoscale materials have been nominated to the National Toxicology Program for toxicological evaluation. The National Institute for
Safety and Health, the EPA and the National Science Foundation are seeking applications for research proposals on the potential implications of nanotechnology and manufactured nanomaterials on human health and the environment. The Agency for Toxic
Substances and Disease Registry has proposed to evaluate nanomaterials for development of a toxicological profile pursuant to CERCLA. In addition, EPA is studying how nanomaterials should be approached under existing laws, such as the Toxic
Substances Control Act, and whether new regulations may be needed. One or more of these efforts may eventually result in regulations which potentially could affect our business in the area of nanotechnology. In February 2007, EPA issued a
Nanotechnology White Paper, which contains recommendations for research on risks and potential exposure pathways for nanomaterials, but does not indicate how EPA may eventually regulate such materials. In July 2007, EPA announced the development of
a voluntary Nanoscale Materials Stewardship Program under the Toxic Substances Control Act (TSCA) and invited comment on two documents, Concept Paper for the Nanoscale Materials Stewardship Program under TSCA and TSCA Inventory
Status of Nanoscale SubstancesGeneral Approach. One example of a voluntary effort is the June 2007 Nano Risk Framework, a tool for evaluating and addressing the potential risks of nanoscale materials, jointly developed by DuPont and
Environmental Defense. While these developments demonstrate increasing interest in this area, at this time, it is not possible to say more precisely whether and what form of nanotechnology regulations may be adopted and how they may affect our
business.

We have constructed an ethanol production facility, Blue Flint Ethanol, LLC, located at the GRE Coal Creek pulverized coal
electric power station near Underwood, North Dakota. The ethanol industry sector manufactures ethanol, principally from industrial corn. Ethanol production facilities can emit volatile organic compounds and carbon monoxide into the air. In 2002, the
EPA began investigating a suspected pattern of noncompliance with the Prevention of Significant Deterioration/New Source Review requirements of the Clean Air Act within the ethanol industry. The Clean Air Acts New Source Review program
requires a source to install pollution controls and undertake other preconstruction obligations to control air pollution emissions. Subsequent investigations of several companies in the ethanol industry found them to be in violation for failure to
obtain either Prevention of Significant Deterioration or minor source permits for new construction and/or modifications made at their facilities. The EPA has negotiated consent decrees with several companies to bring their ethanol plants into
compliance with the air pollution requirements. In May 2007, EPA revised its permitting rules to raise the threshold for ethanol plants from 100 tons per year to 250 tons per year. This change means fewer facilities may trigger the major source
permitting requirements. EPA has been sued over this regulation, and the case is still pending. Our ethanol production facility is subject to air pollution permitting and emission control regulatory requirements.

Section 45. Our coal cleaning business is subject to compliance with the terms of Section 45 of the Internal Revenue Code for the
production and sale of refined coal.

The term refined coal means a fuel which (i) is a liquid, gaseous, or solid fuel
produced from coal (including lignite) or high carbon fly ash, including such fuel used as a feedstock, (ii) is sold by the taxpayer with the reasonable expectation that it will be used for purpose of producing steam, (iii) is certified by
the taxpayer as resulting (when used in the production of steam) in a reduction of at least 20 percent of the emissions of nitrogen oxide and either sulfur dioxide or mercury released when burning the refined coal (excluding any dilution caused

by materials combined or added during the production process), as compared to the emissions released when burning the feedstock coal or comparable coal
predominantly available in the marketplace as of January 1, 2003, and (iv) is produced in such a manner as to result in an increase of at least 50 percent in the market value of the refined coal (excluding any increase caused by materials
combined or added during the production process), as compared to the value of the feedstock coal. In order to qualify for the Section 45 tax credits, the refined coal facility must be placed in service before January 1, 2009. In addition,
a refined coal production facility does not include any facility the production from which is allowed as a credit under Section 45K.

Section 45 currently provides a tax credit of $5.877 per ton of refined coal produced by the taxpayer at a refined coal facility during the 10-year period beginning on the date the facility was originally placed in service and sold by
a taxpayer to an unrelated party during such 10-year period. The credit amount is adjusted each year for inflation. The tax credit is also subject to phase out to the extent that reference price of the fuel used as feedstock exceeds the
reference price for fuel in 2002 ($31.90) multiplied by the inflation adjustment factor for the applicable calendar year times 1.7. The reference price for fuel used as feedstock for refined coal for 2007 is $48.35. Because this amount did not
exceed $31.90 times 1.3433 times 1.7 ($72.85), no phase out of the credit is applicable for calendar year 2007.

Section 45K.
Our coal-based solid alternative (or synthetic) fuel business has been subject to compliance with the terms of Section 45K (formerly Section 29) of the Internal Revenue Code. By law, Section 45K tax credits for alternative fuel
produced from coal expire on December 31, 2007.

Tax credits claimed by an alternative fuel plant operator are phased out prior to
their scheduled expiration date of December 31, 2007, if the reference price of oil exceeds the lower end of a phase out range, and are eliminated entirely if the reference price exceeds the higher end of that range, with the
beginning and end of the range being adjusted annually for inflation. Because the calendar year 2005 reference price of oil was below the bottom end of the range, there was no phase-out of the credit for qualified fuel sold in 2005. However, for
calendar year 2006, the reference price for oil exceeded the bottom end of the range, and the phase out for the credit for qualified fuel sold in 2006 was 33%. For calendar 2007, we estimate that the phase-out range (computed by increasing the 2006
inflation adjustment factor by 2%) begins at $56.16 and completes phase-out at $70.50 per barrel. While the calendar 2007 phase-out percentage can not be finalized at the current time, as of September 30, 2007, an estimated phase-out percentage
of 54% is our best estimate of what the phase-out percentage for calendar 2007 would be, using available information as of that date. As of October 31, 2007, the estimated phase-out percentage for calendar 2007 would be approximately 70%. The
reference price of oil and the inflation adjustment factor are determined annually (and released in the first week of April for the previous year), while the predetermined oil price range is fixed, but adjusted annually for inflation. The reference
price of oil is defined as the U.S. Energy Information Agencys estimate of the annual average wellhead price per barrel for all domestic crude oil not subject to regulation by the U.S. Tax credits are usually claimed by corporations according
to the tax year in which the alternative fuel is actually produced and sold, which may be different than the calendar year. There are approximately 24 states/regions that comprise the U.S. average crude oil price as determined by the United States
Energy Information Administration, with western U.S. crude oil prices often significantly lower than other, more recognized crude oil types.

In June 2003, the Internal Revenue Service (IRS) stated, in summary, that it has had reason to question the scientific validity of test procedures and results that have been presented as evidence that fuel underwent a significant
chemical change, and is currently reviewing information regarding these test procedures and results. In October 2003, the IRS stated in summary that it continued to question whether processes it had approved produced the necessary level of
chemical change required under Section 45K and a related revenue ruling. Nonetheless, the IRS indicated that the industrys chemical change test procedures and results were scientifically valid if applied in a consistent and unbiased
manner. The IRS expressed continuing concerns regarding the sampling and data/record retention practices prevalent in the alternative fuels industry.

We and our licensees are subject to audit by the IRS. The IRS may challenge whether we or our licensees satisfy the requirements of Section 45K, or applicable PLRs, including placed-in-service requirements, or
may

attempt to disallow Section 45K tax credits for some other reason. The IRS has initiated audits of us and certain licensee-taxpayers who claimed Section 45K
tax credits, and the outcome of any such audit is uncertain. The inability of a licensee to claim Section 45K tax credits would reduce our future income from the licensee.

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

Risks Relating to Our Business

Because the markets for our construction materials products are heavily dependent on the residential construction and remodeling market, our revenues could decrease
as a result of events outside our control that impact home construction and home improvement activity.

There has been a severe
slowing in 2007 of new housing starts and in home sales generally. Bank foreclosures have put a large number of homes into the market for sale, effectively limiting some of the incentives to build new homes. While our construction materials business
relies upon the home improvement and remodeling markets as well as new construction, we have experienced a slow down in sales activity in 2007. Interest rate hikes, limits on credit availability, further foreclosures and an oversupply of homes for
sale in the market may adversely affect homeowners ability or desire to engage in construction or remodeling, resulting in a continued or further slowdown in new construction or remodeling and repair activities, which may materially adversely
affect our revenues.

The construction markets are seasonal. The majority of our construction materials sales are in the residential
construction market, which tends to slow down in the winter months. If there is more severe weather than normal, or other events outside of our control, there may be a negative effect on our revenues if we are not able to increase market share.

Our construction materials business has been strengthened by the sales growth of new products. If we are unable to continue to successfully
expand our new product sales, our revenue growth may be adversely affected.

Headwaters growth strategy includes the
introduction of new construction material products into HCMs sales, marketing, and distribution systems. We have had success increasing our revenues in part because of sales in new product categories. If we are unable to sustain new
product sales growth, HCM sales may more closely follow the general industry slow down in new residential construction and remodeling activity, which will negatively affect our revenue and growth.

A significant increase in the price of materials used in the production of our construction materials products that cannot be passed on to customers could have a
significant adverse effect on our net income. Furthermore, we depend upon limited sources for certain key production materials, the interruption of which would materially disrupt our ability to manufacture and supply products, resulting in lost
revenues and the potential loss of customers.

Eldorados architectural stone manufacturing processes require key production
materials including cement, oxides, packaging materials, and certain types of rubber-based products. The suppliers of these materials to



17



---

##### Table of Contents

Eldorado may experience capacity or supply constraints in meeting market demand that limit Eldorados ability to obtain needed production materials on a
timely basis or at expected prices. Eldorado has no long-term contracts with suppliers. Eldorado does not currently maintain large inventories of production materials and alternative sources meeting Eldorados requirements could be difficult to
arrange in the short term. A significant increase in the price of these materials that cannot be passed on to customers could have a significant adverse effect on our net income. Additionally, Eldorados manufacturing and ability to provide
products to its customers could be materially disrupted if this supply of materials was interrupted for any reason. Such an interruption and the resulting inability to supply Eldorados customers with products could adversely impact
Eldorados revenues and our relationships with Eldorados customers.

Certain of Tapcos products, which provide a majority
of Tapcos revenues, are manufactured from polypropylene, which material is sold to Tapco by a single supplier. The price of polypropylene is primarily a function of manufacturing capacity, demand and the prices of petrochemical feedstocks,
crude oil and natural gas liquids. Historically, the market price of polypropylene has fluctuated, and significantly increased in 2007. A significant increase in the price of polypropylene that cannot be passed on to customers could have a
significant adverse effect on our net income. There is no long-term contract with Tapcos polypropylene supplier. Tapco does not maintain large inventories of polypropylene and alternative sources meeting Tapcos requirements could be
difficult to arrange in the short term. Therefore, Tapcos manufacturing and ability to provide products to its customers could be materially disrupted if this supply of polypropylene was interrupted for any reason. Such an interruption and the
resulting inability to supply Tapcos customers with products could adversely impact Tapcos revenues and potentially our relationships with Tapcos customers.

Interruption of Tapcos ability to immediately ship individual or custom product orders could harm Tapcos reputation and result in lost revenues if customers turn to other sources for products.

Tapcos construction materials business is highly dependent upon rapid shipments to contractors and distributors throughout
the United States of individual orders, a large portion of which orders are manufactured upon demand to meet customer specifications. If there is significant interruption of business at any of Tapcos manufacturing plants or with Tapcos
computer systems that track customer orders and production, Tapco is at risk of harming its reputation for speed and reliability with important customers and losing short-term and long-term revenues if these customers turn to other sources.

Tapcos revenues would be materially adversely affected if it lost one or more of its three major customers.

Three of Tapcos customers together accounted for approximately 29% of its revenues in its fiscal year ended September 30, 2007. There are no
long-term contracts in place with these customers. Accordingly, a loss of or significant decrease in demand from these customers would have a material adverse effect on Tapcos business.

If HRIs coal-fueled electric utility industry suppliers fail to provide HRI with high-value CCPs because of environmental regulations or otherwise,
HRIs costs could increase and supply could decrease, hindering growth or decreasing our revenue.

HRI relies on the production
of CCPs by coal-fueled electric utilities. HRI has occasionally experienced delays and other problems in obtaining high-value CCPs from its suppliers and may in the future be unable to obtain high-value CCPs on the scale and within the time frames
required by HRI to meet its customers needs. The Clean Air Mercury Rule implemented under the 1990 Clean Air Act Amendments may result in the implementation of additional technologies at power plants to reduce mercury emissions that could
negatively affect fly ash quality. For example, activated carbon may be injected into power plant exhaust gases to capture mercury. This process may increase the carbon collected with the fly ash and may make the fly ash undesirable for concrete.
Carbon removal processes are technically challenging and expensive. If HRI is unable to obtain CCPs or if it experiences a delay in the delivery of high-value or quality CCPs, HRI will have a reduced supply

##### Table of Contents

of CCPs to sell or may be forced to incur significant unanticipated expenses to secure alternative sources or to otherwise maintain supply to its customers.
Moreover, its revenues could be adversely affected if CCP sales volumes cannot be maintained or if customers choose to find alternatives to HRIs products.

Headwaters Resources, or HRI, primarily sells fly ash for use in concrete; if use of fly ash does not increase, Headwaters Resources may not grow.

HRIs growth has been and continues to be dependent upon the increased use of fly ash in the production of concrete. HRIs marketing initiatives emphasize the environmental, cost and performance advantages
of replacing portland cement with fly ash in the production of concrete. If HRIs marketing initiatives are not successful, HRI may not be able to sustain its growth.

If portland cement or competing replacement products are available at lower prices than fly ash, our sales of fly ash as a replacement for portland cement in concrete products could suffer, causing a decline in
HRIs revenues and net income.

An estimated 76% of HRIs revenues for the fiscal year ended September 30, 2007 were
derived from the sale of fly ash as a replacement for portland cement in concrete products. At times, there may be an overcapacity of cement in regional markets, causing potential price decreases. The markets for HRIs products are regional, in
part because of the costs of transporting CCPs, and HRIs business is affected by the availability and cost of competing products in the specific regions where it conducts business. If competing products become available at prices equal to or
less than fly ash, HRIs revenues and net income could decrease.

Because demand for CCPs sold by HRI is affected by fluctuations in weather and
construction cycles, HRIs revenues and net income could decrease significantly as a result of unexpected or severe weather or slowdowns in the construction industry.

HRI manages and markets CCPs and uses CCPs to produce construction materials. Utilities produce CCPs year-round. In comparison, sales of CCPs are
generally keyed to construction market demands that tend to follow national trends in construction with predictable increases during temperate seasons and decreases during periods of severe weather. HRIs CCP sales have historically reflected
these seasonal trends, with the largest percentage of total annual revenues being realized in the quarters ended June 30 and September 30. Low seasonal demand normally results in reduced shipments and revenues in the quarters ended
December 31 and March 31.

The CCP industry is cyclical because of its dependence on building construction and highway
construction, including infrastructure repair, and is also affected by changes in general and local economic conditions. State construction budgets are affected adversely by economic downturns. HRIs sales could significantly decrease as a
result of a downturn in the economy in one or more markets that it serves.

The profitability of HES depends upon the operational success of a new
business.

Because of the end of HESs legacy synthetic fuel licensing and chemical reagent sales business as of
December 31, 2007, HES began development of its new coal cleaning business. During 2007, HES completed construction on three coal cleaning facilities and began operations. We have plans to develop additional coal cleaning facility operations
during 2008. To successfully operate its facilities, HES must produce and market a quality fuel, addressing operational issues including feedstock availability and cost, construction and operability of equipment, successful separation of minerals
including ash, sulfur, and mercury, product moisture and Btu content, overall costs of operations, as well as marketing and sales of the finished product, which is generally of smaller particle size (fines) and which may be more
difficult to sell than run-of-mine coal. This is a new business for HES, and to date, operations and sales have been modest. The profitability of HES depends on the ability of HES to increase production and sales of cleaned coal. If these facilities
operate at low production levels or cannot produce fuel satisfactory to customers, revenues will be materially adversely affected.

##### Table of Contents

HES may not qualify for tax credits under Section 45 of the Internal Revenue Code (Section 45)
which will adversely affect our profitability.

Section 45 provides a tax credit for the production and sale of refined coal.
To date, the Internal Revenue Service (IRS) has issued very little 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,
HES believes that its coal cleaning facilities will be eligible for Section 45 refined coal tax credits. However, 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 HES 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 HES is not successful in claiming Section 45 credits from its coal cleaning facilities, its profitability will be materially adversely affected.

When the tax credits under Section 45K (formerly Section 29) of the Internal Revenue Code (Section 45K) expire at the end of 2007, our
profitability will be adversely affected.

HES has 28 licensed facilities using its coal-based synthetic fuel technologies. In
addition, HES sells reagents used at approximately 35 facilities owned by our licensees and other customers. License fees and reagent sales accounted for approximately 25% of our total revenues in the fiscal year ended September 30, 2007 and a
higher percentage of our net income. HESs license fees and revenues from sales of chemical reagents depend on the ability of our licensees and customers to manufacture and sell qualified alternative fuels that generate tax credits. By law,
Section 45K tax credits are not available for alternative fuel sold after December 31, 2007. In addition, there have been initiatives from time to time to consider the early repeal or modification of Section 45K. When Section 45K
expires at the end of 2007 or if it is repealed or adversely modified, we believe that alternative fuel facilities will curtail production because alternative fuel operations will not be profitable absent the tax credits. When our licensees close
their facilities after 2007 or if they reduce production activities sooner because of high oil prices, it will have a material adverse effect on amount, recognition and timing of our revenues and net income.

Section 45K tax credits are subject to phase-out if the unregulated average annual oil price reaches the IRS established phase-out range.

Tax credits claimed by an alternative fuel facility owner are reduced prior to their scheduled expiration on December 31, 2007 if the
reference price of oil exceeds the lower end of a phase-out range, and are eliminated entirely if the reference price exceeds the higher end of that range, with the beginning and end of the range being adjusted annually for inflation.
The reference price of oil is defined as the U.S. Energy Information Agencys estimate of the annual average wellhead price per barrel for all domestic crude oil not subject to regulation by the United States. In April 2008, the IRS is expected
to announce the reference price and the phase-out range of oil prices for calendar year 2007. For example, in April 2007, the IRS announced that the reference price for calendar 2006 was $59.69 per barrel and that the phase-out range for 2006 began
at $55.06 per barrel and ended with a $0 tax credit at $69.12 per barrel. Because the calendar year 2006 reference price fell within the range, there was a 33% phase-out of the credit for qualified fuel sold in 2006.

For calendar 2007, Headwaters estimates that the phase-out range (computed by increasing the 2006 inflation adjustment factor by 2%) begins at $56.16 and
completes phase-out at $70.50 per barrel. While the



20



---

##### Table of Contents

calendar 2007 phase-out percentage can not be finalized at the current time, Headwaters estimates that based on actual oil prices for January through
September 2007 and published NYMEX oil prices for October through December 2007, a 54% phase-out would result. If the Section 45K tax credits are phased out in whole or in material part, the amounts and timing of recognition of Headwaters
revenue, net income and cash flow will be severely affected.

The rising price of oil has had an impact on the decisions of facility owners
concerning alternative fuel production in the last quarter of calendar year 2007. Headwaters and its licensees and customers closely watch oil price trends and will continue to consider whether or not to operate facilities depending upon their
respective views of oil prices. Some facility owners have attempted to protect their positions by purchasing oil futures hedges and have requested that Headwaters share the cost of such hedges, while others have considered these actions too risky
and expensive, and have elected to simply curtail or eliminate production based upon an assessment that high oil prices indicate phase-out likelihood. Because Headwaters believes that the 2007 reference price will be within the phase-out range, the
effective tax rate was increased as a result of the estimated phase-out percentage. Decisions by our licensees or customers to curtail or eliminate production during the last quarter of calendar 2007 will affect profitability and cash flow,
including the timing of recognition of revenue.

A significant increase in the price of petrochemical feedstocks used to make latex materials which
are in turn used in the production of HES reagents that cannot be passed on to customers could have an adverse effect on net income. Further, HES depends upon a single supplier for the production of reagents, the interruption of which would
materially disrupt HESs ability to supply products to its customers, resulting in lost revenues.

HES reagents are
manufactured from latex by a single supplier, Dow Reichhold LLC. The price of latex is primarily a function of manufacturing capacity, demand and the prices of petrochemical feedstocks, crude oil and natural gas liquids. Historically, the market
price of latex has fluctuated, and significantly increased in 2007. Some contracts allow cost pass through. Further significant increases in the price of latex that cannot be passed on to customers could have an adverse effect on our net income for
the first quarter of fiscal 2008. HES does not inventory reagents for sale to customers and alternative sources meeting HESs requirements would be difficult to arrange. Therefore, HESs ability to provide reagents to its customers could
be materially disrupted if the supply of reagents or feedstock latex materials were interrupted for any reason. Such an interruption and the resulting inability to supply HESs customers with reagents could adversely impact HESs revenues
in fiscal 2008.

If the IRS challenges or disallows Section 45K tax credits claimed by Headwaters or our licensees, HESs profitability may
decrease because future production by these licensees may decrease.

The IRS may challenge whether HES or its licensees satisfy the
requirements of Section 45K, or applicable PLRs, 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 the outcome of any such audit is uncertain. In the event that tax credits are disallowed, licensees may seek recovery from HES for operational or other reasons, although we believe there would be no basis for such
claims.

The availability and price of corn purchased by Blue Flint Ethanol, LLC (BFE) can be affected by weather, disease, demand from
other users of corn, government programs and other factors beyond BFEs control. In addition, fluctuations in ethanol prices could adversely affect BFEs ethanol revenues.

BFE, our joint venture with GRE to produce ethanol from corn, began production in the first quarter of calendar 2007. The availability and price of corn
is subject to wide fluctuations due to unpredictable factors such as weather, plantings, crop disease, demand for corn from other users, government farm programs and policies, changes in demand resulting from population growth, and production of
similar and competitive crops. These factors have historically caused volatility in corn prices, demand and supplies and, consequently, cause volatility in BFEs operating results. Increased demand and/or reduced supply of corn adversely
affects our profitability by increasing the cost of raw materials used in BFEs operations.

##### Table of Contents

The ethanol and biodiesel industry in the U.S. has grown rapidly over the last few years and our
success will depend on whether demand for ethanol increases concurrently or if the increased production results in excess capacity. Currently, it appears that the ethanol industry is producing product in excess of the markets
ability to blend, store, transport, sell and deliver ethanol-based fuels. This excess supply is putting downward pressure on the sales prices for ethanol to producers, and could adversely affect BFEs revenues and operating results.

Our new businesses, processes and technologies may not be successfully developed, operated and marketed, which could affect our future profitability.

Although we have developed or acquired many new businesses, processes and technologies (e.g., ethanol, heavy oil upgrading and coal
cleaning), commercialization of these businesses and technologies are in early stages. Commercial success of these new businesses and technologies will depend on our ability to enter into agreements with customers, licensees and/or joint venturers
to further develop and provide adequate funding to commercialize the new businesses and technologies, as well as to develop markets for the products and technologies. We may not be able to enter into these agreements and adequate funding may not be
available to fully develop and successfully commercialize our new businesses and technologies. Further, we may not be able to profitably operate our new businesses or market our technologies or products produced from them.

Our growth requires continued investment of capital. If we cannot invest additional capital into new and existing businesses, we may not be able to
sustain or increase our growth.

Our operations require both maintenance and growth capital. A key part of our
business strategy has been to expand through complementary acquisitions, which has required significant capital. In addition, commercialization of our energy technologies, such as coal cleaning and heavy oil upgrading, has required and will require
significant debt and equity commitments. In 2007, we made significant investments in coal cleaning facilities and to secure coal feedstocks, financed with equity, debt, and other arrangements, and we expect to make additional such investments in
2008 and in future years. If we do not have sufficient capital to make equity investments in new projects and/or cannot find acceptable sources of debt financing, our growth may suffer.

Our construction materials and CCP businesses also require significant capital expenditures. Our senior secured credit facilities limit capital
expenditures for all of Headwaters to approximately $100.0 million plus the carryover of $70.4 million from fiscal 2007 and prior years for fiscal year 2008. We believe that we will need substantially all of this capital expenditure limitation
in fiscal year 2008 for maintenance, growth of existing businesses and new growth initiatives.

Headwaters is conducting business in China and other
foreign countries, where intellectual property and other laws, as well as business conditions, may leave our intellectual property, products and technologies vulnerable to duplication by competitors and create uncertainties as to our legal rights
against such competitors actions.

Headwaters has and is expected to continue to license or otherwise make its technology,
including its nanotechnology, heavy oil upgrading and coal liquefaction technology, available to entities in China and other foreign countries. There is a risk that foreign intellectual property laws will not protect our intellectual property to the
same extent as under United States laws, leaving us vulnerable to competitors who may attempt to copy our products, processes or technologies. Further, the legal system of China is based on statutory law. Under this system, prior court decisions may
be cited as persuasive authority but do not have binding precedential effect. Since 1979, the Chinese government has been developing a comprehensive system of commercial laws and considerable progress has been made in the promulgation of laws and
regulations dealing with economic matters, such as corporate organization and governance, foreign investment, commerce, taxation and trade. As these laws, regulations and legal requirements are relatively new and because of the limited volume of
published case law and judicial interpretations and the non-binding nature of prior court decisions, the interpretation and enforcement of these laws, regulations and legal requirements involve some uncertainty. These uncertainties

could limit the legal protection or recourse available to us. In addition, dependence on foreign licenses and conducting foreign operations may subject us to
increased risk from political change, ownership issues or repatriation or currency exchange concerns.

Significant increases in energy and
transportation costs that cannot be passed on to customers could have a significant adverse effect on net income.

We purchase a
significant amount of energy from various sources to conduct our operations, including fossil fuels and electricity for production of building products and diesel fuel for distribution of our products and for production-related vehicles. In
addition, fuel cost increases have increased truck and rail carrier transportation costs for our products. Fuel cost increases have in the past and may in the future adversely affect the results of our operations and our financial condition. Prices
and availability of all petroleum products are subject to political, economic and market factors that are generally outside of our control.

We
operate in industries subject to significant environmental regulation, and compliance with and changes in regulation could add significantly to the costs of conducting business.

The coal-based operations of HES and the CCP operations of HRI and their respective customers and licensees, together with new projects such as the
ethanol plant and the acquisition of a hydrogen peroxide plant in Korea, are subject to federal, state, local and international environmental regulations that impose limitations on the discharge of pollutants into the air and water and establish
standards for the treatment, storage and disposal of waste products, which add to the costs of doing business and expose us to potential fines for non-compliance. If the costs of environmental compliance increase for any reason, we may not be able
to pass on these costs to customers. In order to establish and operate the alternative fuel plants, coal cleaning plants, power plants and operations to collect and transport CCPs and bottom ash, we, our licensees and customers have obtained various
state and local permits and must comply with processes and procedures that have been approved by regulatory authorities. Any failure to comply could result in the issuance of substantial fines and penalties and cause us to incur environmental
liabilities.

Certain HCM manufacturing operations, including those of Eldorado and Tapco, are also subject to environmental regulations
and permit requirements. If HCM and its subsidiaries and affiliates cannot obtain or maintain required environmental permits for their existing and planned manufacturing facilities in a timely manner or at all, they may be subject to additional
costs and/or fines.

The ethanol industry sector manufactures ethanol, principally from industrial corn. Ethanol production facilities can
emit volatile organic compounds and carbon monoxide into the air. In 2002, EPA began investigating a suspected pattern of noncompliance with the Prevention of Significant Deterioration/New Source Review (PSD/NSR) requirements of the Clean Air Act
within the ethanol industry. The Clean Air Acts NSR program requires a source to install pollution controls and undertake other preconstruction obligations to control air pollution emissions. Subsequent investigations of several companies in
the ethanol industry found them to be in violation for failure to obtain either PSD or minor source permits for new construction and/or modifications made at their facilities. EPA has negotiated consent decrees with several companies to bring their
ethanol plants into compliance with the air pollution requirements. Our ethanol production facility located at the GRE Coal Creek pulverized coal electric power station near Underwood, North Dakota, is subject to air pollution permitting and
emission control regulatory requirements. If this facility cannot maintain required environmental permits or maintain compliance with environmental regulations, it may be subject to additional costs and/or fines.

HTIs ordinary course of business requires using its facilities to perform research and development activities involving coal, oil, chemicals and
energy technologies, including liquefaction of coal. As a result, petroleum and other hazardous materials have been and are present in and on HTIs properties. Regulatory noncompliance or accidental discharges, fires, or explosions, in spite of
safeguards, could create environmental or safety liabilities. Therefore, our operations entail risk of environmental damage and injury to people, and we could incur liabilities in the future arising from the discharge of pollutants into the
environment, waste disposal practices, or accidents.

We are involved in litigation and claims for which we incur significant costs and are exposed to significant
liability.

We are a party to some significant legal proceedings and are subject to potential claims regarding operation of our
business. These proceedings will require that we incur substantial costs, including attorneys fees, managerial time and other personnel resources and costs in pursuing resolution, and adverse resolution of these proceedings could hurt our
reputation. With respect to the cases referred to in BusinessLitigation, the following amount of damages is being sought by the counter parties:

Boynton: Boynton seeks declaratory relief as well as compensatory damages in the approximate amount of $25 million plus punitive damages.

We have ongoing litigation and claims incurred during the normal course of business, including the items referred to above. We intend to vigorously
defend and/or pursue our rights in these actions. We do not currently believe that the outcome of these actions will have a material adverse effect on our operations, cash flows or financial position; however, it is possible that a change in the
estimates of probable liability could occur, and the change could be significant.

We have significant competition in our industries which may cause
demand for our products and services to decrease.

We experience significant competition in all of our segments and geographic
regions. A failure to compete effectively or increased competition could lead to price cuts, reduced gross margins and loss of market share, which could decrease our profitability. Many of our competitors have greater financial, management and other
resources than us and may be able to take advantage of acquisitions and other opportunities more readily. In certain instances we must compete on the basis of superior products and services rather than price, thereby increasing the costs of
marketing our services to remain competitive. See ITEM 1, Competition, for more information on the competition faced by Headwaters in all of its segments.

Our business strategy to diversify and grow through acquisitions may result in integration costs, poor performance and dilution to existing stockholders.

An important aspect of our business strategy has been and continues to be diversification and growth through acquisitions. Our ability to successfully
implement our strategy is subject to a number of risks, including difficulties in identifying acceptable acquisition candidates, consummating acquisitions on favorable terms and obtaining adequate financing, which may adversely affect our ability to
develop new products and services and to compete in our markets. In addition, if we consummate acquisitions through an exchange of our securities, our existing stockholders could suffer dilution.

If we do not successfully integrate newly acquired businesses with our existing businesses, we may not realize the expected benefits of the acquisitions,
and the resources and attention required for successful integration may interrupt the business activities of acquired businesses and our existing businesses. Successful management and integration of acquisitions are subject to a number of risks,
including difficulties in assimilating acquired operations, loss of key employees, diversion of managements attention from core business operations, assumption of contingent liabilities, incurrence of potentially significant write-offs, and
various employee issues, such as issues related to human resource benefit plans, and an increase in employment and discrimination claims and claims for workers compensation. Each business acquisition also requires us to expand our operational
and financial systems, which increases the complexity of our information technology systems. Implementation of controls, systems and procedures may be costly and time-consuming and may not be effective. This strategy may not improve our operating
results and acquisitions may have a dilutive effect on existing stockholders.

If our internal controls over financial reporting under Section 404 of the Sarbanes-Oxley Act are not
adequate, our reputation could be harmed and we could be subject to regulatory scrutiny, civil or criminal penalties or stockholder litigation.

Section 404 of the Sarbanes-Oxley Act of 2002 requires that we evaluate and report on our system of internal controls. If we fail to maintain the adequacy of our internal controls, we could be subject to
regulatory scrutiny, civil or criminal penalties or stockholder litigation. Any inability to provide reliable financial reports could harm our business. Section 404 of the Sarbanes-Oxley Act also requires that our independent auditors report on
managements evaluation of our system of internal controls. We have documented and tested our system of internal controls to provide the basis for our report for the year ended September 30, 2007. The growth and diversification of our
business through acquisitions complicates the process of developing, documenting, maintaining and testing internal controls. No assurance can be given that in the future there may not be significant deficiencies or material weaknesses that would be
required to be reported in the future.

If we are unable to manage the growth of our business successfully, our revenues and business prospects could
suffer.

We have experienced significant growth recently, both internally and through acquisitions. We may not be able to
successfully manage the increased scope of our operations or a significantly larger and more geographically diverse workforce as we expand. Any failure to successfully manage growth could harm our business and financial results. Additionally, growth
increases the demands on our management, our internal systems, procedures and controls. To successfully manage growth, we must add administrative staff and periodically update and strengthen our operating, financial and other systems, procedures and
controls, which will increase our costs and may reduce our profitability. We may be unable to successfully implement improvements to our information and control systems in an efficient or timely manner and may discover deficiencies in existing or
future systems and controls.

Unauthorized use of or infringement claims regarding our proprietary intellectual property could adversely affect our
ability to conduct our business.

We rely primarily on a combination of trade secrets, patents, copyright and trademark laws and
confidentiality procedures to protect our intellectual property. Despite these precautions, unauthorized third parties may misappropriate, infringe upon, copy or reverse engineer portions of our technology or products. We do not know if current or
future patent applications will be issued with the scope of the claims sought, if at all, or whether any patents issued will be challenged or invalidated. Our business could be harmed if we infringe upon the intellectual property rights of others.
We have been, and may be in the future, notified that we may be infringing intellectual property rights possessed by third parties. If any such claims are asserted against us, we may seek to enter into royalty or licensing arrangements. There is a
risk in these situations that no license will be available or that a license will not be available on reasonable terms, precluding our use of the applicable technology. Alternatively, we may decide to litigate such claims or attempt to design around
the patented technology. To date, while no single patent or trademark is material to our business and the issues described in this paragraph have not resulted in significant cost or had an adverse impact on our business, future actions could be
costly and would divert the efforts and attention of our management and technical personnel.

Our capital structure affects our flexibility in responding to changing business and economic conditions and
results in high interest costs.

As of September 30, 2007, we had approximately $542.5 million of total debt outstanding,
including $210 million of senior indebtedness under our senior secured credit facilities and $332.5 million of our 2.875% and 2.5% convertible senior subordinated notes (the Convertible Notes). Subject to restrictions in our senior
secured credit facility, we may also incur significant amounts of additional debt for working capital, capital expenditures and other purposes. Our combined debt total could have important consequences, including the following:



| |  |  | we may have difficulty borrowing money for working capital, capital expenditures, acquisitions or other purposes because of our existing debt load and because our
borrowings are secured by all of our assets;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we will need to use a large portion of our cash flow to pay interest and the required principal payments on our debt, which will reduce the amount of money
available to finance our operations, capital expenditures and other activities; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our senior secured credit facility has a variable rate of interest, which exposes us to the risk of increased interest rates
| | - |  | ----------------------------------------------------------------------------------------------------------------------------

Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness depends on our future performance, which
to a certain extent is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service our debt and make necessary capital
expenditures. If unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive.

Covenant restrictions under our senior secured credit facility may limit our ability to operate our business in a manner required to sustain profitability and
generate growth.

Our senior secured credit facilities, contain, among other things, covenants that may restrict our ability to
finance future operations or capital needs, to acquire additional businesses or to engage in other business activities. The senior secured credit facilities impose specified limitations on joint venture investments and new acquisitions. In addition,
our senior secured credit facilities set forth covenants requiring us to maintain specified financial ratios and to satisfy certain financial condition tests which may require that we take action to reduce our debt or to act in a manner contrary to
our business objectives. A breach of any of these covenants could result in a default under our senior secured credit facilities, in which event our lenders could elect to declare all amounts outstanding to be immediately due and payable. If we are
not able to repay our obligations when they become due or they are accelerated, the lenders could foreclose on our assets. The indenture for the notes does not restrict the amount of indebtedness, including senior indebtedness, that we may incur.

Risks Related to our Common Stock

The price of
our common stock historically has been volatile. This volatility may affect the price at which you could sell your common stock, and the sale of substantial amounts of our common stock could adversely affect the price of our common stock.

The market price for our common stock has varied between a high of $25.44 in February 2007 and a low of $12.52 in November 2007 in the
twelve month period ended October 31, 2007. This volatility may affect the price at which you could sell your common stock, and the sale of substantial amounts of our common stock could adversely affect the price of our common stock. Our stock
price is likely to continue to be volatile and subject to significant price and volume fluctuations in response to market and other factors, including the other factors discussed in Risks Relating to Our Business; variations in our
quarterly operating results from our expectations

or those of securities analysts or investors; downward revisions in securities analysts estimates; and announcement by us or our competitors of
significant acquisitions, strategic partnerships, joint ventures or capital commitments.

In the past, following periods of volatility in
the market price of their stock, many companies have been the subject of securities class action litigation. If we became involved in securities class action litigation in the future, it could result in substantial costs and diversion of our
managements attention and resources and could harm our stock price, business, prospects, results of operations and financial condition.

In addition, the broader stock market has experienced significant price and volume fluctuations in recent years. This volatility has affected the market prices of securities issued by many companies for reasons unrelated to their operating
performance and may adversely affect the price of our common stock. In addition, our announcements of our quarterly operating results, changes in general conditions in the economy or the financial markets and other developments affecting us, our
affiliates or our competitors could cause the market price of our common stock to fluctuate substantially.

In addition, the sale of
substantial amounts of our common stock could adversely impact its price. As of September 30, 2007, we had outstanding approximately 42.2 million shares of our common stock and options to purchase approximately 2.4 million shares of
our common stock (of which approximately 2.3 million were exercisable as of that date). We also had outstanding approximately 0.5 million stock appreciation rights as of September 30, 2007, of which approximately 0.1 million were
exercisable. The sale or the availability for sale of a large number of shares of our common stock in the public market could cause the price of our common stock to decline.

Conversion of the 2.875% Convertible Notes may cause volatility in our stock price and will dilute the ownership interest of existing stockholders.

Although our diluted earnings per share calculation treats the 2.875% Convertible Notes as if they were already converted into common stock, sales in the
public market of the common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. Anticipated conversion of the notes into shares of our common stock could depress the price of our common stock. In
addition, the existence of the Convertible Notes may encourage short selling by market participants because the conversion of the notes could be used to satisfy short positions. Conversion of the Convertible Notes will dilute the ownership interests
of existing stockholders, including holders who had previously converted their notes.

We have never paid dividends and do not anticipate paying any
dividends on our common stock in the future, so any short-term return on your investment will depend on the market price of our capital stock.

We currently intend to retain any earnings to finance our operations and growth. The terms and conditions of our senior secured credit facility restrict and limit payments or distributions in respect of our capital
stock.

Delaware law and our charter documents may impede or discourage a takeover, which could cause the market price of our shares to decline.

We are a Delaware corporation, and the anti-takeover provisions of Delaware law impose various impediments to the ability of a
third party to acquire control of us, even if a change in control would be beneficial to our existing stockholders. In addition, our board of directors has the power, without stockholder approval, to designate the terms of one or more series of
preferred stock and issue shares of preferred stock, including the adoption of a poison pill, which could be used defensively if a takeover is threatened. The ability of our board of directors to create and issue a new series of
preferred stock and certain provisions of Delaware law and our certificate of incorporation and bylaws could impede a merger, takeover or other business combination involving us or discourage a potential acquirer from making a tender offer for our
common stock, which, under certain circumstances, could reduce the market price of our common stock.

The following graph shows a comparison of the cumulative total stockholder return, calculated on a
dividend reinvestment basis, for September 30, 2002 through September 30, 2007, on our Common Stock with the New York Stock Exchange Composite Index and the Dow Jones Wilshire Building Materials & Fixtures Index. The
comparison assumes $100 was invested on September 30, 2002. Please note that historic stock price performance shown on the graph is not indicative of future price performance. We have not paid dividends on our Common Stock.

LOGO

As of November 2, 2007 there were 328 stockholders of record of our common stock. We have not paid
dividends on our common stock to date and do not intend to pay dividends in the foreseeable future. Pursuant to the terms of our senior secured credit arrangement (see Note 8 to the consolidated financial statements), we are prohibited from paying
cash dividends so long as any of the long-term debt is outstanding. We intend to retain earnings to finance the development and expansion of our business. Payment of common stock dividends in the future will depend upon our debt covenants, our
ability to generate earnings, our need for capital, our investment opportunities and our overall financial condition, among other things.

The information required by this item regarding equity compensation plans is incorporated by reference to the information set forth in Item 12 of this Annual Report on Form 10-K. See Note 11 to the consolidated financial statements for
a description of securities authorized for issuance under equity compensation plans.

We did not make any unregistered sales of our equity
securities during the year ended September 30, 2007. We did not repurchase any shares of our equity securities during the fourth quarter of the year ended September 30, 2007.

|ITEM 6. | SELECTED FINANCIAL DATA
|------- | -----------------------

The following selected
financial data are derived from our consolidated financial statements. This information should be read in conjunction with the consolidated financial statements, related notes and other financial information included in this Form 10-K. The selected
financial data as of and for the years ended September 30, 2003 and 2004 and as of September 30, 2005 are derived from audited financial statements not included in this Form 10-K. The selected financial data as of September 30, 2006
and 2007 and for the years ended September 30, 2005, 2006, and 2007 were derived from our audited financial statements included in this Form 10-K.

As described in Note 13 to the consolidated financial statements, we acquired several companies in 2006 and one company in 2007. We also made several material acquisitions in 2004. The results of operations for these
companies for the periods from the acquisition dates through September 30, 2007 have been consolidated with our results. None of their results of operations up to the dates of acquisition have been included in our consolidated results.

In 2004, we recognized revenue relating to funds deposited in an escrow account totaling approximately $27.9 million, most of which
related to prior periods. In 2005, we successfully settled certain litigation which resulted in increased operating income, primarily related to prior periods, of approximately $52.4 million. Also in 2005, we early adopted the fair value method of
accounting for stock-based compensation required by SFAS No. 123R and recorded approximately $33.8 million of stock-based compensation expense, most of which was of a non-recurring nature (see Note 11 to the consolidated financial statements).
In 2007, we recognized tax credit-based license fee revenue totaling approximately $31.5 million, most of which related to prior periods (see Note 14 to the consolidated financial statements). Also in 2007, we recorded an impairment of goodwill of
$98.0 million (see Note 7 to the consolidated financial statements).

|ITEM 7. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

The following discussion and analysis should be read in conjunction with the information set forth under the caption entitled ITEM 6.
SELECTED FINANCIAL DATA and the consolidated financial statements and related notes included in this Form 10-K. Our fiscal year ends on September 30 and unless otherwise noted, future 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. As described in more detail in Note 13 to the consolidated financial statements, we made one acquisition in 2007 and several insignificant acquisitions in 2006. These entities results of operations for
the periods from the acquisition dates through September 30, 2007 have been consolidated with our results; their operations up to the dates of acquisition have not been included in the consolidated results for any period.

We currently operate in three industries: construction materials, coal combustion products (CCPs) and alternative energy. In the construction
materials 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 and other product sales. In the alternative energy segment,
we are focused on reducing waste and increasing the value of energy feedstocks, primarily in the areas of low-value coal and oil. Revenues for the alternative energy segment consist primarily of sales of chemical reagents and license fees.

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 over-reliance on the legacy alternative 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 construction materials business, through several large and small acquisitions in 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 is to continue to focus on increased cash flows to reduce debt.

A material amount of our 2007 and prior fiscal year consolidated revenue and net income has been derived from license fees and sales of chemical
reagents, both of which depend on the ability of licensees and other customers to manufacture and sell qualified synthetic fuel that generates 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 own an interest. The following issues exist related to tax credits.

By law,
Section 45K tax credits for synthetic fuel produced from coal expire for synthetic fuel sold after December 31, 2007. When Section 45K expires, we expect our licensees synthetic fuel facilities to close because we do not believe
that production of synthetic fuel will be profitable absent the tax credits. When our licensees close their facilities or significantly reduce production activities, it will have a material adverse effect on our revenue, net income and cash flow, in
addition to the current material adverse effect caused by phase-out concerns.

Section 45K tax credits are subject to phase-out after
the average annual U.S. wellhead oil price (reference price) reaches a beginning phase-out threshold price, and are eliminated entirely if the reference price reaches the full phase-out price. There was a partial phase-out of tax credits
for calendar 2006 of approximately 33% and



32

##### Table of Contents

we currently expect a significant phase-out of tax credits for calendar 2007. Most of our licensees stopped production for a period of time in calendar 2006.
As of September 30, 2007, all of our licensees were producing synthetic fuel, but some have indicated intent to stop production prior to December 31, 2007. These events have materially adversely affected both the amount and timing of
recognition of our revenue, net income and cash flow in 2006 and 2007, and will likely have a material adverse effect in 2008, until Section 45K expires at the end of calendar 2007 and the calendar 2007 reference price and phase-out range are
published in the quarter ending June 30, 2008. Reference is made to Notes 10 and 14 to the consolidated financial statements where there is more information on phase-out and other uncertainties related to Section 45K tax credits that have
affected our business historically and that will continue to affect our business in 2008.

Our acquisition strategy targets businesses that
are leading players 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 addition, 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 which operate an ethanol plant located in North Dakota and a hydrogen peroxide plant in South Korea. We are also investing in other alternative energy projects such as coal cleaning and the use of
nanocatalysts to engineer coal for emissions reduction and to enhance the refining of heavy crude oils into lighter transportation fuels.

Our CCPs and construction materials businesses are affected by seasonality, with the highest revenue and profitability produced in the June and September quarters. With CCPs, our 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 also intend to continue our efforts to expand usage of high-value CCPs, develop more uses for lower-value CCPs, such as blending, and expand the
use of CCPs in our construction materials businesses.

In 2005 and 2006, we focused on the integration of our large 2004 acquisitions,
including the marketing of diverse construction materials products through our national distribution network. We became highly leveraged as a result of those acquisitions, but have reduced our outstanding debt since that time through cash generated
from operations, from an underwritten public offering of common stock and from proceeds from settlement of litigation. We intend to continue to focus on repaying long-term debt while continuing to look for diversification opportunities.

Critical Accounting Policies and Estimates

Our
significant accounting policies are identified and described in Note 2 to the consolidated financial statements. The preparation of consolidated financial statements in conformity with U. S. generally accepted accounting principles requires us to
make estimates and assumptions that affect i) the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and ii) the reported amounts of revenue and expenses during
the reporting period. Actual results could differ materially from those estimates.

We continually evaluate our policies and estimation
procedures. Estimates are often based on historical experience and on assumptions that are believed to be reasonable under the circumstances, but which could change in the future. Some of our accounting policies and estimation procedures require the
use of substantial judgment, and actual results could differ materially from the estimates underlying the amounts reported in the consolidated financial statements. Such policies and estimation procedures have been reviewed with our Audit Committee.
The following is a discussion of critical accounting policies and estimates.

License Fee Revenue Recognition. We currently license
our technologies to the owners of 28 coal-based solid alternative fuel facilities in the U.S. License agreements contain a quarterly earned royalty fee generally set at a prescribed dollar amount per ton or a percentage of the tax credits earned by
the licensee. Recurring license



33

##### Table of Contents

fees or royalty payments are recognized in the period when earned, which coincides with the sale of alternative fuel by our licensees, provided standard
revenue recognition criteria such as amounts being fixed or determinable are met. In most instances, we receive timely reports from licensees notifying us of the amount of solid synthetic fuel sold and the royalty due us under the terms
of the respective license fee agreements. Additionally, we have experienced a regular pattern of payment by these licensees of the reported amounts.

Estimates of license fee revenue earned, where required, can be reliably made based upon historical experience and/or communications from licensees with whom an established pattern exists. In some cases, however, such
as when a licensee is beginning to produce and sell synthetic fuel or when a synthetic fuel facility is sold by a licensee to another entity, and for which there is no pattern or knowledge of past or current production and sales activity, there may
be more limited information available to estimate the license fee revenue earned. In these situations, we use such information as is available and where possible, substantiate the information through such procedures as observing the levels of
chemical reagents purchased by the licensee and used in the production of the solid synthetic fuel. In certain limited situations, we are unable to reliably estimate the license fee revenues earned during a period, and revenue recognition is delayed
until a future date when sufficient information is known from which to make a reasonable estimation.

In 1996, we entered into an agreement
with AJG Financial Services, Inc. The agreement provided for AJG to pay royalties and allowed AJG to purchase proprietary chemical reagent material from us. In October 2000, we filed a complaint in the Fourth District Court for the State of Utah
against AJG alleging that it had failed to make payments and to perform other obligations under the agreement. We asserted claims including breach of contract and sought money damages as well as other relief. AJGs answer to the complaint
denied our claims and asserted counter-claims based upon allegations of misrepresentation and breach of contract.

This litigation came to
the trial phase in January 2005. The jury reached a verdict substantially in our favor and the court entered a judgment for us against AJG in the amount of approximately $175.0 million which included approximately $32.0 million in prejudgment
interest. In May 2005, we entered into a settlement agreement with AJG which provided for payments to us in the amount of $50.0 million at the time of settlement (which payment was received in May 2005), $70.0 million (related to a contract
modification for use of technology) in January 2006, and certain quarterly payments based upon tax credits associated with AJGs facilities for calendar years 2005 through 2007. Payments based upon tax credits associated with AJGs
facilities for the first three quarters of calendar year 2005 were received in January 2006, with all other quarterly payments for 2005 through 2007 payable 45 days after the end of each quarter. Payments based upon tax credits for 2005 through 2007
are subject to downward adjustment or elimination if a phase-out of section 29 tax credits occurs due to high oil prices.

We recognized
the $50.0 million contract litigation settlement gain, net of payments due to a third party, as a reduction in operating costs and expenses in 2005. The $70.0 million, net of payments due to a third party, is being recognized as revenue over
calendar years 2005 through 2007. The ongoing quarterly payments based upon tax credits are being recognized as revenue in accordance with our revenue recognition policy for license fee revenue.

In connection with the settlement of the AJG litigation, we also recognized approximately $8.2 million of revenue from a licensee with an indirect
interest in that litigation, all of which related to periods prior to January 1, 2005. Ongoing revenue from this licensee is also being recognized in accordance with our revenue recognition policy for license fee revenue.

The amount of license fee revenue recognized during 2006 and 2007 was negatively affected by reduced revenues being recognized for certain licensees
whose license agreements call for us to be paid a portion of the tax credits earned by the licensee. Certain accounting rules limit revenue recognition to amounts that are fixed or determinable. Therefore, due to uncertainties related to
phase-out of Section 45K tax credits and other licensee-specific factors, the timing of revenue recognition was delayed for certain licensees during fiscal 2006 and 2007.

Due to publication of the Section 45K calendar 2006 reference price and the phase-out range,
finalization of calendar 2006 phase-out was made possible during the quarter ended June 30, 2007. As a result of the availability of this information and the clarification of other licensee-specific factors, certain calendar 2006 and prior year
license fee revenue totaling approximately $31.5 million was recognized in 2007. This amount related to periods ending on or prior to December 31, 2006 and was recognized in 2007 when it met the fixed or determinable recognition
criterion and it was remote that any negative adjustment would be required in the future. We have applied the same policy in 2007 with regard to the recognition of revenue for calendar 2007 tax credit-based license fees. The final determination of
revenue to be collected pertaining to fiscal and calendar year 2007 will not occur until the calendar 2007 reference price and phase-out range are published in the quarter ending June 30, 2008.

Income Taxes. Significant estimates and judgments were required in the calculation of our income tax provisions for the years presented, most
particularly in 2006 and 2007. One of the key estimates affecting our 2006 and 2007 tax provisions is the amount of Section 45K (formerly Section 29) tax credits that will ultimately be available related to our 19% interest in an entity
that owns and operates a coal-based solid alternative fuel production facility, plus two other smaller alternative fuel facilities that we own and operate (see Note 10 to the consolidated financial statements).

The calendar 2006 Section 45K tax credit phase-out percentage was not finalized until the quarter ended June 30, 2007. The calendar 2007
phase-out percentage will not be finalized until the quarter ending June 30, 2008. As of September 30, 2007, an estimated phase-out percentage of 54% is our best estimate of what the phase-out percentage for calendar 2007 would be, using
available information as of that date. It is certain that the phase-out percentage for calendar 2007 will be different from this estimate. As of October 31, 2007, the estimated phase-out percentage for calendar 2007 would be 70%. We estimate
that NYMEX average oil prices would need to exceed $110 for the period October 1, 2007 through December 31, 2007 for full phase-out to occur in calendar 2007. The effect of the finalization of the calendar 2006 phase-out percentage, which
was published in 2007, was a decrease in income tax expense of approximately $1.5 million which amount was included in the 2007 tax provision. Likewise, the effect on income taxes of the change in the calendar 2007 phase-out percentage from 54% to
the actual percentage for the year will be recorded to income tax expense in fiscal 2008, when the calendar 2007 actual oil prices and the phase-out range are known. The effect of this adjustment could be material to our 2008 income tax expense.

As described in more detail in Note 7 to the consolidated financial statements, we recorded a goodwill impairment charge of $98.0 million
in 2007. The impairment charge is not deductible for tax purposes and therefore had a significant negative effect on our reported effective tax rate for 2007.

As described in Note 11 to the consolidated financial statements, approximately $3.9 million of stock-based compensation in 2007 resulted from the early voluntary cancellation of SARs and other stock-based awards,
requiring an acceleration of expense recognition for the grant-date fair value that had not been recognized as of the cancellation dates. As a result of the cancellation of the stock-based awards, approximately $10.0 million of deferred tax assets
were written off.

As described in more detail in Note 2 to the consolidated financial statements, we are required to adopt Interpretation
No. 48, Accounting for Uncertainty in Income Taxes  an Interpretation of FASB Statement No. 109 (FIN 48) at the beginning of our fiscal 2008 year, or October 1, 2007, with a transition adjustment to retained
earnings as of October 1, 2007, if material. Based upon our evaluation as of September 30, 2007, the cumulative effect of adopting FIN 48 could be a decrease in retained earnings and an increase in income tax liabilities for uncertain tax
positions of approximately $18.0 million; however, this amount is subject to revision when we complete our evaluation.

The calculation of
our tax liabilities involves uncertainties in the application of complex tax regulations in multiple jurisdictions. We recognize potential liabilities for anticipated tax audit issues in the U.S. and state tax



35

##### Table of Contents

jurisdictions based on our estimate of whether, and the extent to which, additional taxes and interest will be due. If events occur and the payment of these
amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when we determine the liabilities are no longer probable or necessary. If our estimate of tax liabilities proves
to be less than the ultimate assessment, a further charge to expense would result.

In evaluating our ability to recover our recorded
deferred tax assets, in full or in part, all available positive and negative evidence, including our past operating results and our forecast of future taxable income on a jurisdiction by jurisdiction basis, is considered and evaluated. In
determining future taxable income, we are responsible for assumptions utilized including the amount of federal, state and international pre-tax operating income, the reversal of temporary differences and the implementation of feasible and prudent
tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we are using to manage our underlying businesses.

Valuation of Long-Lived Assets, including Intangible Assets and Goodwill. Long-lived assets consist primarily of property, plant and equipment,
intangible assets and goodwill. Intangible assets consist primarily of identifiable intangible assets obtained in connection with acquisitions. These intangible assets are being amortized using the straight-line method over their estimated useful
lives.

Goodwill consists of the excess of the purchase price for businesses acquired over the fair value of identified assets acquired,
net of liabilities assumed. In accordance with the requirements of SFAS No. 142, we do not amortize goodwill, all of which relates to acquisitions that occurred from 2001 through 2007. SFAS No. 142 requires us to periodically test for
goodwill impairment at least annually, or more frequently if evidence of possible impairment arises. We perform our annual impairment testing as of June 30, using the two-step process described in Note 7 to the consolidated financial
statements. As of June 30, 2007, there were five distinguishable reporting units with goodwill, three of which were in the construction materials segment. There was one reporting unit with goodwill in each of the CCPs and alternative energy
segments. As a result of ongoing changes in the operations and management of the businesses in the construction materials segment, and in accordance with the requirements contained in SFAS No. 142, SFAS No. 131 and EITF Abstract Topic
D-101, Clarification of Reporting Unit guidance in Paragraph 30 of SFAS No. 142, we expect goodwill in the three historical reporting units in this segment will be aggregated and tested for impairment as one reporting unit for
goodwill impairment testing in 2008.

With the exception of the Tapco reporting unit for 2007, all of the step 1 tests indicated that the
fair values of the reporting units, calculated primarily using discounted expected future cash flows, exceeded their carrying values. Accordingly, step 2 of the impairment tests was not required to be performed for those reporting units, and no
impairment charges were necessary. As a result of the depressed residential housing and remodeling market and changes in cost of capital, the Tapco reporting unit failed step 1, requiring completion of step 2, which resulted in a determination that
Tapcos goodwill was impaired. Accordingly, a non-cash impairment charge of $98.0 million was recorded in 2007. The impairment did not affect our cash position, cash flow from operating activities or senior debt covenants, and will not have any
impact on future operations.

In addition to the annual review, we evaluate, based on current events and circumstances, the carrying value
of long-lived assets, including intangible assets and goodwill, as well as the related amortization periods, to determine whether adjustments to these amounts or to the useful lives are required. Changes in circumstances such as technological
advances, or changes in our business model or capital strategy could result in the actual useful lives differing from our current estimates. In those cases where we determine that the useful lives of property, plant and equipment or intangible
assets should be changed, we amortize the net book value in excess of salvage value over the revised remaining useful lives, thereby prospectively adjusting depreciation or amortization expense as necessary.

The carrying value of a long-lived asset is considered impaired when the anticipated cumulative undiscounted cash flow from that asset is less than its
carrying value. In that event, a loss is recognized based on



36



---

##### Table of Contents

the amount by which the carrying value exceeds the fair market value of the long-lived asset. Indicators of impairment include such things as a significant
adverse change in legal factors or in the general business climate, a decline in operating performance indicators, a significant change in competition, or an expectation that significant assets will be sold or otherwise disposed of. In 2006, the
construction materials segment revised downward the estimated useful lives of certain assets resulting in accelerated depreciation charges in order to fully depreciate the assets over shorter periods. This is the primary reason for the increased
depreciation expense in 2006 as compared to 2005 and in 2007 as compared to 2006.

It is possible that some of our tangible or intangible
long-lived assets or goodwill could be impaired in the future and that resulting write-downs could be material.

Stock-Based
Compensation. As described in more detail in Note 11 to the consolidated financial statements, we early adopted the fair value method of accounting for stock-based compensation required by SFAS No. 123R, effective as of October 1,
2004, the beginning of our 2005 fiscal year. Most of the 2005 stock-based compensation resulted from the expense associated with grants of immediate-vested SARs and from the acceleration of vesting of certain stock options. Approximately $3.9
million of the 2007 stock-based compensation resulted from the early voluntary cancellation of SARs and other stock-based awards, requiring an acceleration of expense recognition for the grant-date fair value that had not been recognized as of the
cancellation dates.

We recognize compensation expense equal to the grant-date fair value of stock-based awards for all awards expected to
vest, over the period during which the related service is rendered by grantees. The fair value of stock-based awards is determined primarily using the Black-Scholes-Merton option pricing model (B-S-M model), developed for use in
estimating the fair value of traded options that have no vesting restrictions and that are fully transferable. Option valuation models require the input of certain subjective assumptions, including expected stock price volatility. For stock-based
awards, we use the graded vesting or accelerated method to allocate compensation expense over the requisite service periods. Our estimated forfeiture rates are based largely on historical data and ranged from 0% to 5% from 2005 to 2007,
depending on the type of award and the award recipients. As of September 30, 2007, the estimated forfeiture rate for most unvested awards was 1% per year.

The fair values of stock options and SARs were estimated using the B-S-M model, adjusted where necessary to account for specific terms of awards that the B-S-M model does not have the capability to consider. We used
the services of an independent valuation firm to validate our fair value estimates and assumptions and also to determine certain necessary adjustments to the B-S-M model output. One such adjustment was used in determining the fair value of SARs
which had a cap on allowed appreciation. For those SARs, the output determined by the B-S-M model was reduced by an amount determined by a Quasi-Monte Carlo simulation to reflect the reduction in fair value associated with the appreciation cap.

Expected stock price volatility was estimated using primarily historical volatilities of our common stock. Implied volatilities of traded
options on our stock, volatility predicted by a Generalized AutoRegressive Conditional Heteroskedasticity model, and an analysis of volatilities used by other public companies in comparable lines of business were also considered.
Risk-free interest rates used were the US Treasury bond yields with terms corresponding to the expected terms of the awards being valued. In estimating expected lives, we considered the contractual and vesting terms of awards, along with historical
experience; however, due to insufficient historical data from which to reliably estimate expected lives, we used estimates based on the simplified method set forth by the SEC in Staff Accounting Bulletin No. 107, where expected life
is estimated by summing the awards vesting term and the contractual term and dividing that result by two. The reduction in value related to grantee payment for certain immediate-vested SARs was estimated by management based on the terms of the
payment requirements and other factors.

As of September 30, 2007, there was approximately $2.9 million of total compensation cost
related to nonvested awards not yet recognized. This unrecognized compensation cost is expected to be recognized over a



37

##### Table of Contents

weighted-average period of approximately 1.9 years. Due to the grant of stock-based awards subsequent to September 30, 2007, the amount of total
compensation cost related to nonvested awards has increased, and the weighted-average period over which compensation cost will be recognized has changed.

The adoption of SFAS No. 123R, combined with the settlement of the AJG litigation described above, was a contributing factor in our decision to grant employee incentive awards in 2005, in particular to grant
fewer options and more SARs, including many that vested immediately, the granting of performance-based awards, and the acceleration of vesting of stock options. The early voluntary cancellation of SARs and other stock-based awards in 2007 was a
direct result of the low stock price as compared to the exercise prices of the cancelled SARs.

Year Ended September 30, 2007 Compared to Year
Ended September 30, 2006

The information set forth below compares our operating results for the year ended September 30, 2007
(2007) with operating results for the year ended September 30, 2006 (2006).

Revenue. Total revenue for
2007 increased by approximately 8% to $1.21 billion as compared to $1.12 billion for 2006. The major components of revenue are discussed in the sections below.

Construction Materials Segment. Sales of construction materials during 2007 were $544.1 million with a corresponding direct cost of $383.5 million. Sales of construction materials during 2006 were $573.4
million with a corresponding direct cost of $394.1 million. The decrease in sales of construction materials during 2007 was due primarily to the effects of a depressed residential housing and remodeling market which impacted sales across most of our
product lines. The housing market slowdown also was the primary reason for the decline in gross margin percentage from 2006 to 2007. Because a substantial amount of our revenues in this segment are dependent on the housing market, we anticipate
continuing impact in 2008 from the current slowdown in the housing industry.

CCP Segment. CCP revenues for 2007 were $306.4 million
with a corresponding direct cost of $217.6 million. CCP revenues for 2006 were $281.2 million with a corresponding direct cost of $206.4 million. The increase in CCP revenues and in the gross margin percentage during 2007 were due primarily to a
combination of continued strong demand for CCPs and upward pricing trends in most concrete markets. The growth in demand for CCPs is due in part to certain regional shortages of portland cement for which CCPs are a substitute. The cement shortages
also resulted in increased prices for CCPs in several markets.

Alternative Energy Segment. Our alternative energy segment revenue
consists primarily of chemical reagent sales, license fee revenue related to our solid alternative fuel technologies, and to a lesser extent, sales of synthetic fuel from two solid alternative fuel production facilities that we own. The major
components of revenue for the alternative energy segment are discussed in the sections below.

As described previously and in Note 14 to
the consolidated financial statements, a material amount of our 2007 and prior fiscal year consolidated revenue has been derived from license fees and sales of chemical reagents, both of which depend on the ability of licensees and other customers
to manufacture and sell qualified synthetic fuel that generates tax credits under Section 45K of the Internal Revenue Code. By law, Section 45K tax credits for synthetic fuel produced from coal expire for synthetic fuel sold after
December 31, 2007. When Section 45K expires, we expect our licensees synthetic fuel facilities to close because we do not believe that production of synthetic fuel will be profitable absent the tax credits. When our licensees close
their facilities or significantly reduce production activities, it will have a material adverse effect on our revenue, in addition to the current material adverse effect caused by phase-out concerns.

Sales of Chemical Reagents. Chemical reagent sales during 2007 were $190.1 million with a corresponding direct cost of $151.6 million. Chemical
reagent sales during 2006 were $143.0 million with a corresponding



38



---

##### Table of Contents

direct cost of $108.1 million. Chemical reagent sales in 2007 were higher than in 2006 primarily due to increased synthetic fuel production by most of our
licensees (resulting in increased sales of $32.6 million) and other customers with whom we do not have a license agreement (resulting in increased sales of $14.5 million). We believe there has been less concern in 2007 over phase-out of
Section 45K tax credits than existed in 2006, due partly to mitigation efforts such as hedging, which has resulted in increased synthetic fuel production. The gross margin percentage for 2007 of 20% was lower than the 2006 gross margin
percentage of 24% due primarily to increases in the cost of product, which in turn was related to increases in the costs of petroleum-based materials.

License Fees. During 2007, we recognized license fee revenue totaling $112.6 million, an increase of $37.9 million from $74.7 million of license fee revenue recognized during 2006. The amount of license fee
revenue recognized during 2006 and 2007 was negatively affected by reduced revenues being recognized for certain licensees whose license agreements call for us to be paid a portion of the tax credits earned by the licensee. Due to uncertainties
related to phase-out and other licensee-specific factors, revenue recognition was deferred for certain licensees during fiscal 2006 and 2007.

Due to publication of the calendar 2006 reference price and the phase-out range for that year, finalization of calendar 2006 phase-out was made possible during the quarter ended June 30, 2007. As a result of the availability of this
information and the clarification of other licensee-specific factors, certain calendar 2006 and prior year license fee revenue totaling approximately $31.5 million was recognized in 2007. This amount related to periods ending on or prior to
December 31, 2006 and was recognized in 2007 when it met the fixed or determinable recognition criterion and it was remote that any negative adjustment would be required in the future. We have applied the same policy in 2007 with
regard to the recognition of revenue for calendar 2007 tax credit-based license fees. The final determination of revenue to be collected pertaining to fiscal and calendar year 2007 will not occur until the calendar 2007 reference price and phase-out
range are published in the quarter ending June 30, 2008. Reference is made to our policy disclosures discussed previously.

Other
Alternative Energy Segment Revenues.The majority of other alternative energy segment revenue is comprised of sales of synthetic fuel, which during 2007 were $45.5 million with a corresponding direct cost of $52.5 million. Sales of synthetic
fuel during 2006 were $42.5 million with a corresponding direct cost of $49.2 million. Revenue from the sale of synthetic fuel has a negative gross margin, which is more than compensated for by the income tax credits expected to be earned from the
sales of the synthetic fuel.

Amortization and Research and Development Expenses. The decrease in amortization expense of $1.4
million from 2006 to 2007 was due primarily to intangible assets that have been fully amortized. Research and development expense increased by $4.3 million from 2006 to 2007 primarily because of increased spending in our joint research efforts with
Evonik Industries AG (formally Degussa AG) related to hydrogen peroxide and in developmental efforts related to our nanotechnologies. Both amortization and research and development expenses are currently expected to decrease somewhat in 2008 from
the reported 2007 amounts.

Selling, General and Administrative Expenses. These expenses increased $17.6 million, or 13%, to $155.6
million for 2007 from $138.0 million for 2006. The increase in 2007 was due primarily to a $10.9 million increase in payroll and incentive pay at the operating business unit level, a $3.3 million increase in litigation-related costs, and a $2.4
million increase in stock-based compensation. A majority of the increase in payroll costs relates to growth initiatives at the operating business unit level, and increased incentive pay related to improved performance at certain operating business
units. The increase in litigation costs was due to a net credit recorded in 2006 because of positive developments in certain legal matters. Those developments resulted in reduced likelihood of ultimate legal liability and the reversal of previously
expensed litigation costs. The higher stock-based compensation was due to the cancellation of SARs and other stock-based awards in 2007 and the resultant acceleration of expense recognition for unrecognized compensation cost that remained as of the
cancellation dates.

Other Income and Expense. During 2007, we reported net other expense of $42.0 million compared to net other
expense of $44.0 million during 2006. The change of $2.0 million was comprised of a decrease in net

interest expense of $2.9 million and an increase in other expenses of $0.9 million. Net interest expense decreased from $34.0 million in 2006 to $31.1
million in 2007, due primarily to the lower interest rate (2.50%) on the $160.0 million of convertible senior subordinated notes issued in 2007, and lower average levels of long-term debt in 2007 as compared to 2006. The decrease in interest
expense caused by those factors was partially offset by $2.6 million of accelerated amortization of debt issue costs related to early repayments of senior debt in 2007, a majority of which were funded by net proceeds from the new lower-rate
convertible notes. We currently expect interest expense in 2008 to be somewhat less than the 2007 amount.

The increase in other expenses
of $0.9 million consisted primarily of an increase in costs related to our investment in the coal-based solid alternative fuel production facility described in Note 10 to the consolidated financial statements.

Income Tax Provision. We recorded income tax provisions with an effective tax rate of approximately 26% in 2006 and 66% in 2007 (24%, exclusive of
the $98.0 million goodwill impairment charge, which is not tax-deductible). The effective tax rates are lower than statutory rates primarily due to tax credits related to the two coal-based solid alternative fuel facilities that we own and operate,
plus our 19% interest in an entity that owns and operates another alternative fuel facility (see Note 10 to the consolidated financial statements). The alternative fuel produced at these three facilities through December 2007 qualifies for tax
credits pursuant to Section 45K (formerly Section 29) of the Internal Revenue Code, subject to the uncertainties of phase-out, IRS audit and other risks associated with the tax credits, all as more fully described in Note 14 to the
consolidated financial statements. Excluding the effect of the tax credits in both years and the goodwill impairment charge in 2007, our effective tax rate for 2006 and 2007 would have been approximately 40% and 39%, respectively.

As discussed in Note 10, the Section 45K tax credits used in calculating the income tax provision are estimated as of September 30, 2007. While
the calendar 2007 phase-out percentage can not be finalized at the current time, as of September 30, 2007, the estimated phase-out percentage of 54% represents our best estimate of what the phase-out percentage would be, using available
information as of that date. The effect on income taxes of any change in the calendar 2007 phase-out percentage from 54% to the actual percentage for the year will be recorded to income tax expense in subsequent periods, when the calendar 2007
actual oil prices and the phase-out range are known. Any such effect could be material to our 2008 income tax expense.

Year Ended September 30,
2006 Compared to Year Ended September 30, 2005

The information set forth below compares our operating results for the year ended
September 30, 2006 (2006) with operating results for the year ended September 30, 2005 (2005).

Revenue. Total revenue for 2006 increased by approximately 6% to $1.12 billion as compared to $1.06 billion for 2005. The major components of revenue are discussed in the sections below.

Construction Materials Segment. Sales of construction materials during 2006 were $573.4 million with a corresponding direct cost of $394.1
million. Sales of construction materials during 2005 were $519.9 million with a corresponding direct cost of $346.5 million. The increase in sales of construction materials during 2006 was due primarily to increases in volume, which occurred across
all major product lines, with a lesser impact from price increases related to passing on to customers a portion of raw material cost increases. The primary reasons for the decline in gross margin percentage from 2005 to 2006 were acceleration of
depreciation charges in order to fully depreciate certain assets over shorter estimated useful lives, additional operating costs as production levels were managed downward to account for the downturn in the residential housing market and higher raw
material costs, only a portion of which were passed on to customers.

CCP Segment. CCP revenues for 2006 were $281.2 million with a
corresponding direct cost of $206.4 million. CCP revenues for 2005 were $246.8 million with a corresponding direct cost of $186.1 million. The



40

##### Table of Contents

increase in CCP revenues and in the gross margin percentage during 2006 were due primarily to a combination of continued strong demand for CCPs, upward
pricing trends in most concrete markets, and increased project revenues. In addition, weather conditions in the south central region of the United States have generally been favorable in 2006. The growth in demand for CCPs is due in part to certain
regional shortages of portland cement for which CCPs are a substitute, which can result in an increased percentage of CCPs being used in concrete. The cement shortages also resulted in increased prices for CCPs in several markets.

Alternative Energy Segment. The major components of revenue for the alternative energy segment are discussed in the sections below.

Sales of Chemical Reagents. Chemical reagent sales during 2006 were $143.0 million with a corresponding direct cost of $108.1 million. Chemical
reagent sales during 2005 were $170.3 million with a corresponding direct cost of $120.6 million. The decrease in chemical reagent sales during 2006 was due to decreased synthetic fuel production by our licensees (resulting in decreased sales of
$13.0 million), and by customers with whom we do not have a license agreement (resulting in decreased sales of $14.3 million). The primary reason for decreased synthetic fuel production in 2006 was the potential for significant phase-out of
Section 45K tax credits, resulting in licensees and other customers stopping or significantly curtailing production for a period of time during 2006. The gross margin percentage for 2006 of 24% was lower than 2005s gross margin percentage
of 29% due primarily to increases in the cost of product, which in turn is related to increases in the costs of petroleum-based materials.

License Fees. During 2006, we recognized license fee revenue totaling $74.7 million, a decrease of $34.6 million or 32% from $109.3 million of license fee revenue recognized during 2005. The primary reason for the decrease in license
fee revenue in 2006 compared to 2005 related to significantly reduced revenues being recognized for several licensees whose license agreements call for us to be paid a portion of the value of the tax credits earned by the licensee. Certain
accounting rules limit revenue recognition to amounts that are fixed or determinable. Because the calendar 2006 phase-out percentage for Section 45K tax credits could not be finalized as of September 30, 2006, only
approximately $10.0 million of revenues for these licensees was recognized for the nine months ended September 30, 2006. The amount recognized met the fixed or determinable recognition criterion and it was remote that any negative
adjustment would be required in the future. Additional revenues for these licensees was dependent on the calendar 2006 phase-out percentage of Section 45K, which was not finalized until 2007.

Other Alternative Energy Segment Revenues.Sales of synthetic fuel during 2006 were $42.5 million with a corresponding direct cost of $49.2
million. Sales of synthetic fuel during 2005 were $16.6 million with a corresponding direct cost of $19.2 million. The increase in sales of synthetic fuel from 2005 to 2006 was due to the synthetic fuel facilities starting operations in spring 2005.

Amortization and Research and Development Expenses. There were no material changes in either amortization or research and
development expenses from 2005 to 2006.

Selling, General and Administrative Expenses. These expenses decreased $17.3 million, or
11% to $138.0 million for 2006 from $155.3 million for 2005. The decrease in 2006 was due primarily to significant one-time stock-based compensation costs in 2005 related to the implementation in 2005 of SFAS No. 123R ($22.7 million).
Offsetting this decrease was a $3.5 million increase in marketing expense related to efforts in the construction materials segment to increase awareness and sales of new products.

Contract Litigation Settlement. In 2005, we settled our litigation with AJG. In connection with the litigation settlement, a payment of $50.0
million was received in 2005. This amount, net of payments due to a third party and less the amount recognized as a reimbursement of legal fees (approximately $6.5 million), was reflected as a reduction in operating costs and expenses.

Other Income and Expense. During 2006, we reported net other expense of $44.0 million compared to net other expense of $73.1 million during
2005. The change of $29.1 million was attributable to a decrease in net



41

##### Table of Contents

interest expense of $23.4 million and a decrease in other expenses of $5.7 million. Net interest expense decreased from $57.4 million in 2005 to $34.0
million in 2006, due primarily to significantly lower average levels of long-term debt in 2006 compared to 2005.

The decrease in other
expenses of $5.7 million consisted primarily of a decrease in costs of approximately $9.0 million related to our investment in the coal-based solid alternative fuel production facility described in Note 10 to the consolidated financial statements.
The primary reason for decreased costs for this facility was related to the estimated phase-out percentage for Section 45K tax credits for calendar 2006 of approximately 42%. Partially offsetting the decrease in costs related to our investment
in the alternative fuel facility was an increase of $3.3 million in charges primarily related to a joint venture investment and the disposition of property, plant and equipment.

Income Tax Provision. Our income tax provision for both 2005 and 2006 resulted in an effective tax rate of approximately 26%. The low effective
tax rate for both years is primarily due to tax credits related to the two coal-based solid alternative fuel facilities that we own and operate, plus our 19% interest in an entity that owns and operates another alternative fuel facility (see Note 10
to the consolidated financial statements). Excluding the effect of the tax credits, our estimated effective tax rate for 2005 and 2006 would have been approximately 38.5% and 40%, respectively.

Impact of Inflation and Related Matters

In addition
to the effects of rising oil prices as discussed elsewhere, our operations have been impacted by i) increased cement, polypropylene and poly-vinyl chloride costs in the construction materials segment; ii) rising costs for chemical reagents in the
alternative energy segment; iii) increased fuel costs that have affected transportation costs in most of our business units; and iv) certain regional shortages of cement and aggregate materials. The increased costs of polypropylene, poly-vinyl
chloride, chemical reagents and fuel are directly related to the increase in prices of oil and other petroleum-based materials. The increased costs of cement appear to be caused by a lack of adequate supplies in some regions of the U.S. and
international supply, demand and 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. It is also not possible to predict the impact of
potential future cement supply shortages on our ability to procure needed supplies in our construction materials business.

Liquidity and Capital
Resources

Summary of Cash Flow Activities. Net cash provided by operating activities for the year ended September 30, 2007
(2007) was $150.0 million compared to $223.2 million for the year ended September 30, 2006 (2006). The primary reason for the change in cash provided by operations from 2006 to 2007 was the collection in 2006 of a $70.0
million receivable related to the litigation settlement reached with AJG in 2005, along with other changes in working capital. In 2006 and 2007, the primary investing activities consisted of payments for acquisitions, the purchase of property, plant
and equipment, and investments in joint ventures. In 2007, financing activities consisted primarily of the issuance of a new series of convertible senior subordinated notes and the early repayment of a portion of our senior debt. In 2006, the
primary financing activity consisted of repayments of long-term debt. More details about our investing and financing activities are provided in the following paragraphs.

Investing Activities. Total expenditures for property, plant and equipment in 2007 were not materially different from 2006. Most of the capital expenditures in both periods were incurred by the construction
materials segment; however, in 2007, a higher proportion of total capital expenditures were incurred by the alternative energy segment as compared to 2006. A significant portion of our planned future capital expenditures, which in



42

##### Table of Contents

2008 are currently expected to exceed the 2007 amount, represent expansion of operations, rather than maintenance of operating capacity, primarily due to
growth initiatives in the alternative energy segment. Capital expenditures are limited by our senior debt covenants to $100.0 million annually; however, the cumulative unused amounts of annual capital expenditures limits can be carried forward and
used in subsequent years. As of September 30, 2007, we had approximately $70.4 million of unused amounts of capital expenditures from prior years and we were committed to spend approximately $37.6 million on capital projects that were in
various stages of completion, primarily in the alternative energy segment.

In 2007, we acquired 100% of the ownership interests of a
privately-held company in the construction materials business. Total consideration paid at the date of acquisition of approximately $53.0 million consisted primarily of cash. An additional amount, currently estimated to be approximately $20.0
million, is payable in the future, based on earnings of the acquired entity for the 12 month period ended September 30, 2007 that exceed an agreed-upon threshold. During 2006, we acquired certain assets and assumed certain liabilities of
several privately-held companies in the construction materials industry. Total consideration paid or accrued for these acquisitions was less than $8.0 million. 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. If future earn-out consideration is paid in excess of amounts accrued for any acquisition, goodwill will be
increased accordingly.

We intend to continue to expand our business through growth of existing operations, commercialization of
technologies currently being developed, and strategic acquisitions of products or entities that expand our current operating platform. Acquisitions are an important part of our business strategy and to that end, we routinely review potential
complementary acquisitions, including those in the areas of construction materials, 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 will be used to fund acquisitions of complementary businesses in the chemical, energy, building products and related industries. The 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 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 2006, financing activities consisted primarily
of the repayment of long-term debt. In 2007, as described in more detail in Note 8 to the consolidated financial statements, we issued $160.0 million of 2.50% convertible senior subordinated notes due February 2014. Substantially all of the net
proceeds of approximately $154.6 million, along with $5.2 million of available cash, were used to repay $152.8 million of senior debt and the remaining balance (approximately $7.0 million) of notes payable to a bank. Subsequently, we repaid an
additional $52.5 million of senior debt. In 2007, we also paid approximately $11.8 million for the convertible note hedge and related warrants associated with the issuance of the convertible debt. As of September 30, 2007, we have no long-term
debt repayments that are due prior to 2011. We may, in the future, make optional prepayments of the 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. We expect our positive cash flow to
continue in the future in addition to our ability to access the equity markets if necessary.

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 of an exchange offer.

Reference is made to Note 8 to the consolidated financial
statements for detailed information about our outstanding long-term debt, interest rate hedges, 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 September 30, 2007.

In 2007, cash proceeds from the exercise of options and employee stock
purchases totaled $2.6 million, compared to $8.7 million in 2006. 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, reflected in cash flows from financing activities in the
consolidated statements of cash flows, were not material in 2006 or 2007.

In October 2007, we announced that our board of directors has
authorized a stock repurchase program for up to $15.0 million of our common stock. The purchases will be made from time to time in the open market and will be funded from available working capital. The extent to which we repurchase our common shares
and the timing of such repurchases will be based on several factors, including our stock price, general business and market conditions, and other investment opportunities. The repurchase program may be discontinued at any time.

Working Capital. As of September 30, 2007, our working capital was $163.4 million. Notwithstanding the expiration of Section 45K tax
credits as of December 31, 2007 and the resulting impact on cash flow, we 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. Our cash requirements for income taxes generally
approximate 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 is also some lag in realizing the 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 receive the tax credits. In 2006 and 2007, there has been more variability in the relationship between the income tax provision and income tax payments because the tax provision calculation is materially dependent upon the
estimated phase-out percentage of Section 45K tax credits (see Notes 10 and 14 to the consolidated financial statements). The calendar 2007 phase-out percentage is subject to material change because it is dependent on oil prices for all of
calendar 2007, which are not predictable.

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. 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, are currently expected to consist primarily of capital expenditures, acquisitions and debt service payments on
outstanding long-term debt.

As described in Note 8 to the consolidated financial statements, our senior debt credit facility
provides for up to $60.0 million of borrowings under a revolving credit arrangement, with the ability to increase this amount to $100.0 million, subject to obtaining additional revolving loan commitments. 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. There were no borrowings outstanding under the revolving credit arrangement as of
September 30, 2007, or subsequent thereto. The credit agreement also allows for the issuance of letters of credit, provided there is capacity under the revolving credit arrangement. As of September 30, 2007, six stand-by letters of credit
totaling $6.0 million were outstanding, with expiration dates ranging from March 2008 to September 2009.

During 2006, we acquired certain
assets and assumed certain liabilities of several privately-held companies in the construction materials industry. Total consideration paid or accrued for these acquisitions was less than $8.0 million. 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. In 2007, we acquired 100% of the ownership interests of a privately-held
company in the construction materials business. Total consideration paid at the date of acquisition, of approximately $53.0 million, consisted primarily of cash. An additional amount, currently estimated to be in excess of $20.0 million, is payable
in the future, based on earnings of the acquired entity for the 12 month period ended September 30, 2007 that exceed an agreed-upon threshold.

Reference is made to the caption Compensation Arrangements in Note 14 to the consolidated financial statements for a detailed discussion of potential commitments to certain officers and employees under

employment agreements, long-term incentive cash bonus awards, change in control agreements, performance unit awards, and a contingent commission agreement.
Amounts in addition to those included in the table above could become obligations under the terms of these agreements, depending upon the future events described in Note 14.

We have ongoing litigation and asserted claims which have been incurred during the normal course of business, including the specific matters discussed in
Note 14 to the consolidated financial statements. We intend to vigorously defend or resolve these matters by settlement, as appropriate. We do not currently believe that the outcome of these matters will have a material adverse effect on our
operations, cash flow or financial position.

Historically, costs paid to outside legal counsel for litigation have comprised a majority of
our litigation-related costs. In 2007, we incurred approximately $3.4 million of expense for legal matters, which consisted primarily of costs for outside legal counsel. We currently believe 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 have recorded a total liability as of September 30, 2007 of $1.1 million. Claims and damages sought by claimants in excess of this amount are
not deemed to be probable. Our 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. It is not possible to
estimate what litigation-related costs will be in future periods.

The matters discussed in Note 14 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 us 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
us 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 us to incur
substantial costs, including attorneys fees, managerial time and other personnel resources, in pursuing resolution.

Recent Accounting
Pronouncements

Reference is made to Note 2 to the consolidated financial statements for a discussion of accounting pronouncements that
have been recently issued which we have not yet adopted.



|ITEM 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
|-------- | ---------------------------------------------------------

We are exposed to financial market risks, primarily related to changes in interest rates. We do not use derivative financial instruments for speculative or trading purposes, but have entered into certain hedge
transactions, primarily to limit our variable interest rate exposure. The Blue Flint joint venture also has hedges in place related to variable interest rates and commodities.

As described in more detail in Note 8 to the consolidated financial statements, our senior debt, totaling $210.0 million as of September 30, 2007,
bears interest at a variable-rate. As required by the senior secured credit facility, we entered into agreements to limit our variable interest rate exposure through September 8, 2007. The agreements effectively fix the LIBOR rate at 3.71% for
$150.0 million of this debt. We accounted for these agreements as cash flow hedges, with their fair market value reflected in the consolidated balance sheet as either other assets or other liabilities. The market value of all cash flow hedges at
September 30, 2007 was not material. Total comprehensive income, considering all cash flow hedge agreements in which we are or were a party, was not materially different from net income for any period.

Considering our current balance of variable-rate debt, a change in the interest rate of 1% would change our interest expense by approximately $2.1
million during the 12 months ending September 30, 2008.

|ITEM 9A. | 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 Annual Report on Form 10-K, 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 September 30, 2007, 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 Annual 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.

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 September 30, 2007 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
September 30, 2007 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Managements Report on Internal Control over Financial Reporting

Our management is responsible for establishing and
maintaining adequate internal control over financial reporting. Our internal control system has been designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation and presentation of our financial
statements.

Our management has assessed the effectiveness of internal control over financial reporting as of September 30, 2007 using
the criteria issued by the Committee of Sponsoring Organizations of the Treadway Commission in Internal ControlIntegrated Framework. Based on that assessment, management believes that our internal control over financial
reporting was effective as of September 30, 2007.

Ernst & Young LLP, the independent registered public accounting firm which
audits our consolidated financial statements, has issued the following attestation report on the effectiveness of our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

Headwaters Incorporated

We have audited Headwaters
Incorporateds internal control over financial reporting as of September 30, 2007, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission
(the COSO criteria). Headwaters Incorporateds management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in
the accompanying Managements Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial
reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the
circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial
reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A
companys internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the
assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of
the company are being made

only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk
that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Headwaters Incorporated maintained, in all material respects, effective internal control over financial reporting as of September 30, 2007, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets
of Headwaters Incorporated as of September 30, 2006 and 2007, and the related consolidated statements of income, changes in stockholders equity, and cash flows for each of the three years in the period ended September 30, 2007 and
our report dated November 16, 2007 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

Headwaters Incorporated

We have audited the accompanying
consolidated balance sheets of Headwaters Incorporated as of September 30, 2006 and 2007, and the related consolidated statements of income, changes in stockholders equity, and cash flows for each of the three years in the period ended
September 30, 2007. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for
our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated
financial position of Headwaters Incorporated at September 30, 2006 and 2007, and the consolidated results of its operations and its cash flows for each of the three years in the period ended September 30, 2007, in conformity with U.S.
generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting
Oversight Board (United States), the effectiveness of Headwaters Incorporateds internal control over financial reporting as of September 30, 2007, based on criteria established in Internal Control-Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission and our report dated November 16, 2007 expressed an unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2007



1. Description of Business and Organization

Headwaters Incorporated (Headwaters) is a diversified company providing products, technologies and services in three industries: construction
materials, coal combustion products (CCPs) and alternative energy. Headwaters uses technology to differentiate itself from competitors and to create value in its businesses.

In the construction materials 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 construction materials 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 believes it is uniquely positioned to manufacture an array of building materials that use fly ash, such as block, stucco, and
mortar. Headwaters CCP business is comprised of a nationwide storage and distribution network and revenue is diversified geographically and by market.

In the alternative energy segment, Headwaters is focused on reducing waste and increasing the value of energy 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 licenses technology and sells reagents to the coal-based solid alternative fuel industry. 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.

Headwaters is incorporated in Delaware and has a fiscal year that ends on September 30. Unless otherwise noted, references to years refer to Headwaters fiscal year rather than a calendar year.

2. Summary of Significant Accounting Policies

Principles of ConsolidationThe consolidated financial statements include the accounts of Headwaters, all of its subsidiaries, and other entities in which Headwaters has a controlling interest. In accordance with Financial
Accounting Standards Board Interpretation No. 46R, Consolidation of Variable Interest Entities, as revised, Headwaters is required to consolidate any variable interest entities for which it is the primary beneficiary; however, as of
September 30, 2007, there are none that are material. For investments in entities in which Headwaters has a significant influence over operating and financial decisions (generally defined as owning a voting or economic interest of 20% to 50%),
Headwaters applies the equity method of accounting. In instances where Headwaters investment is less than 20% and significant influence does not exist, investments are carried at cost. All significant intercompany transactions and accounts are
eliminated in consolidation.

As described in more detail in Note 13, Headwaters made one acquisition in 2007 and several insignificant
acquisitions in 2006. These entities results of operations for the periods from the acquisition dates through September 30, 2007 have been consolidated with Headwaters results; their operations up to the dates of acquisition have
not been included in Headwaters consolidated results for any period.

Use of EstimatesThe preparation of consolidated
financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect i) the

reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and ii) the reported
amounts of revenue and expenses during the reporting period. Actual results could differ materially from those estimates.

Segment
Reporting, Major Customers and Other Concentrations of RiskHeadwaters operates in three business segments, construction materials, coal combustion products (CCPs) and alternative energy. Additional information about segments is
presented in Note 3. No customer accounted for over 10% of total revenue in any year presented. Through September 30, 2007, substantially all of Headwaters revenues have been generated from sales in the United States.

Headwaters purchases all of the polypropylene used in its building products from a single supplier and purchases all of the chemical
reagent that is sold to licensees and other customers from a single large international chemical company. Management believes that if necessary, the polypropylene could be obtained from other suppliers, although such a change would be
disruptive. Obtaining an alternative supplier of chemical reagent would most likely not be possible because of the imminent expiration of the Section 45K tax credit program on December 31, 2007, but for the same reason it is not
expected to be necessary (see Note 14). Also as described in more detail in Note 14, a material amount of Headwaters consolidated revenue, net income and cash flow is derived from its Section 45K business, which business will end in 2008.

Revenue Recognition and Cost of RevenueBuilding Materials.Revenue from the sale of construction materials and CCPs is
recognized upon passage of title to the customer, which coincides with physical delivery and assumption of risk of loss by the customer. Estimated sales rebates, discounts and allowances are provided for at the time of sale and are based upon
established policies and historical experience. Revenues include transportation charges and shipping and handling fees associated with delivering products and materials to customers when the transportation or shipping and handling is contractually
provided for between the customer and Headwaters. Cost of construction materials and coal combustion products sold includes shipping and handling fees.

CCP revenues include revenues earned under long-term contracts to dispose of residual materials created by coal-fired electric power generation and revenues earned in connection with certain incidental
construction-related projects. Revenues under long-term contracts are recognized concurrently with the removal of material and are based on the volume of material removed at established prices per ton. Construction-related projects are billed on a
time and materials basis, with revenues and related costs being recognized when time is incurred and materials are consumed. The cost of CCPs sold primarily represents amounts paid to utility companies to purchase product, together with storage and
transportation costs to deliver product to customers. In compliance with contractual obligations, the cost of CCPs purchased from certain utilities is based on a percentage of the net revenues from sale of the CCPs purchased. Costs also
include landfill fees and transportation charges to deliver non-marketable CCPs to landfills.

Alternative Energy. Headwaters
currently licenses its technologies to the owners of 28 coal-based solid alternative fuel facilities from which Headwaters earns license fees and/or revenue from the sale of chemical reagents. Non-refundable advance license fees and royalty payments
have been received from certain licensees under various terms and conditions. These non-refundable license fees and royalties have been deferred and are being recognized on a straight-line basis through December 31, 2007, the period covered by
the related license and royalty agreements and the expiration date of Section 45K tax credits. Recurring license fees or royalty payments are recognized in the period when earned, which coincides with the sale of alternative fuel by
Headwaters licensees, provided standard revenue recognition criteria such as amounts being fixed or

determinable are met. In certain instances, Headwaters is required to pay to third parties a portion of license fees received or cash proceeds from the
sale of chemical reagents. In such cases, Headwaters records the net proceeds as revenue. Revenue from the sale of chemical reagents is recognized upon delivery of product and assumption of the risk of loss by the licensee or non-licensee customer.

Cash and Cash EquivalentsHeadwaters considers all short-term, highly-liquid investments with an original maturity of three
months or less to be cash equivalents. Certain cash and cash equivalents are deposited with financial institutions, and at times such amounts exceed insured depository limits.

ReceivablesAllowances are provided for uncollectible accounts and notes when deemed necessary. Such allowances are based on an
account-by-account analysis of collectibility or impairment plus a provision for non-customer specific defaults based upon historical collection experience. Collateral is not required for trade receivables, but Headwaters performs periodic credit
evaluations of its customers. Collateral is generally required for notes receivable.

InventoriesInventories are stated at the
lower of cost or market (net realizable value). Cost includes direct material, transportation, direct labor and allocations of manufacturing overhead costs and is determined primarily using the first-in, first-out method.

Property, Plant and EquipmentProperty, plant and equipment are recorded at cost. For significant self-constructed assets, cost includes
direct labor and interest. Expenditures for major improvements are capitalized; expenditures for maintenance, repairs and minor improvements are charged to expense as incurred. Except for coal rights, assets are depreciated using the straight-line
method over their estimated useful lives, limited to the lease terms for improvements to leased assets. Coal rights are amortized using the units-of-production method. Upon the sale or retirement of property, plant and equipment, any gain or loss on
disposition is reflected in results of operations (in other income (expense)), and the related asset cost and accumulated depreciation or amortization are removed from the respective accounts.

Intangible Assets and GoodwillIntangible assets consist primarily of identifiable intangible assets obtained in connection with acquisitions
(see Note 13). Intangible assets are amortized using the straight-line method over their estimated useful lives. Goodwill consists of the excess of the purchase price for businesses acquired over the fair value of assets acquired, net of liabilities
assumed. As described in more detail in Note 7, in accordance with Statement of Financial Accounting Standards (SFAS) No. 142, Accounting for Goodwill and Intangible Assets, goodwill is not amortized, but is tested at
least annually for impairment. A goodwill impairment charge was recorded for one reporting unit in 2007. No impairment charges have been required for any other reporting unit or in any other year presented.

Valuation of Long-Lived AssetsHeadwaters evaluates the carrying value of long-lived assets, including intangible assets and goodwill, as
well as the related amortization periods, to determine whether adjustments to these amounts or to the useful lives are required based on current events and circumstances. The carrying value of a long-lived asset is considered impaired when the
anticipated cumulative undiscounted cash flow from that asset is less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair market value of the long-lived asset. Except for the
goodwill impairment charge in 2007, there were no material impairment losses recorded for long-lived assets in any of the years presented.

Debt Issue CostsDebt issue costs represent direct costs incurred for the issuance of long-term debt. These costs are amortized to interest expense over the lives of the respective debt issues using the effective interest

September 30, 2007



method. When debt is repaid early, the portion of unamortized debt issue costs related to the early principal repayment is written off and included in
interest expense.

Financial InstrumentsDerivatives are recorded in the consolidated balance sheet at fair value, as required
by SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended (SFAS No. 133). Accounting for changes in the fair value of a derivative depends on the intended use of the derivative, which
is established at inception. For derivatives designated as cash flow hedges and which meet the effectiveness guidelines of SFAS No. 133, changes in fair value, to the extent effective, are recognized in other comprehensive income until the
hedged item is recognized in earnings. Hedge effectiveness is measured at least quarterly based on the relative changes in fair value between the derivative contract and the hedged item over time. Any change in fair value of a derivative resulting
from ineffectiveness, or an excluded component of the gain or loss, is recognized immediately and is recorded as interest expense.

Headwaters formally documents all hedge transactions at inception of the contract, including identification of the hedging instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the hedge
transaction. This process includes linking the derivatives that are designated as hedges to specific assets, liabilities, firm commitments or forecasted transactions. Headwaters also formally assesses the effectiveness of its hedging instruments on
an ongoing basis. Headwaters has entered into hedge agreements to limit its exposure for interest rate movements and certain commodities.

Income TaxesHeadwaters files a consolidated federal income tax return with substantially all of its subsidiaries and accounts for income taxes in accordance with SFAS No. 109, Accounting for Income Taxes.
Headwaters recognizes deferred tax assets or liabilities for the expected future tax consequences of events that have been recognized in the financial statements or in income tax returns. Deferred tax assets or liabilities are determined based upon
the differences between the financial statement and tax bases of assets and liabilities using enacted tax rates expected to apply when the differences are expected to be settled or realized. Deferred income tax assets are periodically reviewed for
recoverability based on changing events, and valuation allowances are provided as necessary. Expenses for interest and penalties related to income taxes are classified with the income tax provision.

Research and Development CostsResearch and development costs consist primarily of personnel-related costs and are expensed as incurred.

Advertising CostsAdvertising costs are expensed as incurred, except for the cost of certain materials which are capitalized
and amortized to expense as the materials are distributed. Total advertising costs were approximately $7.8 million in 2005, $11.4 million in 2006 and $9.1 million in 2007.

Warranty CostsProvision is made for warranty costs at the time of sale, based upon established policies and historical experience. Warranty
costs were approximately $1.6 million in 2007 and were not material in 2005 or 2006.

ContingenciesIn accounting for legal
matters and other contingencies, Headwaters follows the guidance in SFAS No. 5, Accounting for Contingencies, under which loss contingencies are accounted for based upon the likelihood of an impairment of an asset or the incurrence
of a liability. If a loss contingency is probable and the amount of loss can be reasonably estimated, it is accrued. If a loss contingency is probable but the amount of loss cannot be reasonably estimated, disclosure is made.
If a loss contingency is reasonably possible, disclosure is made, including the potential range of loss, if determinable. Loss contingencies that are remote are neither accounted for nor disclosed. Gain contingencies are
given no accounting recognition until realized, but are disclosed if material.

Stock-Based CompensationAs described in more detail in Note 11, in the quarter ended
June 30, 2005 Headwaters early adopted the fair value method of accounting for stock-based compensation required by SFAS No. 123 (revised 2004), Share-Based Payment (SFAS No. 123R), effective as of
October 1, 2004, the beginning of Headwaters 2005 fiscal year. Accordingly, Headwaters restated its statement of income for the six months ended March 31, 2005 and the restated amounts were used in deriving the statement of income
amounts reported for the 2005 fiscal year.

Stock-based compensation expense is reported within the same operating expense line items as
used for cash compensation expense. Due to immateriality, Headwaters has not capitalized any compensation cost as part of the cost of any asset. Tax benefits resulting from exercise of stock options and stock appreciation rights (SARs)
are reflected in the consolidated statements of changes in stockholders equity and cash flows.

Headwaters recognizes compensation
expense equal to the grant-date fair value of stock-based awards for all awards expected to vest, over the period during which the related service is rendered by grantees. The fair value of stock-based awards is determined primarily using the
Black-Scholes-Merton option pricing model (B-S-M model), developed for use in estimating the fair value of traded options that have no vesting restrictions and that are fully transferable. Option valuation models require the input of
certain subjective assumptions, including expected stock price volatility. For stock-based awards, Headwaters uses the graded vesting or accelerated method to allocate compensation expense over the requisite service periods.
Headwaters estimated forfeiture rates are based largely on historical data and ranged from 0% to 5% from 2005 to 2007, depending on the type of award and the award recipients. As of September 30, 2007, the estimated forfeiture rate for
most unvested awards was 1% per year.

Earnings per Share CalculationEarnings per share (EPS) has been
computed based on the weighted-average number of common shares outstanding. Diluted EPS computations reflect the increase in weighted-average common shares outstanding that would result from the assumed exercise of outstanding stock-based awards,
calculated using the treasury stock method (as modified by SFAS No. 123R), and the assumed conversion of convertible securities, using the if-converted method, when such stock-based awards or convertible securities are dilutive.

Recent Accounting PronouncementsIn July 2006, the Financial Accounting Standards Board (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 recognition threshold and measurement standard, as well as criteria for
subsequently recognizing, derecognizing and measuring tax positions for financial reporting purposes. FIN 48 also requires expanded disclosures with respect to the uncertainty in income taxes. Headwaters is required to adopt FIN 48 at the beginning
of its fiscal 2008 year, or October 1, 2007, with a transition adjustment to retained earnings as of October 1, 2007, if material. Based upon Headwaters evaluation as of September 30, 2007, the cumulative effect of adopting FIN
48 could be a decrease in retained earnings and an increase in income tax liabilities for uncertain tax positions of approximately $18.0 million; however, this amount is subject to revision when Headwaters completes its evaluation.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements (SFAS No. 157) 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 in its 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 (see Note 13), in testing for potential goodwill impairment (see Note 7), for
disclosure of the fair value of financial instruments

(see Note 9), 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.

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 year amounts have been reclassified to conform to the current years presentation. The reclassifications had no effect on net income or total assets.

3. Segment Reporting

Headwaters currently operates
three business segments: construction materials, CCPs and alternative energy. These segments are managed and evaluated separately by management due to differences in their markets, operations, products and services.

In the construction materials segment, Headwaters designs, manufactures, and sells 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.

The CCP segment manages and markets coal combustion products such as fly ash and bottom ash, known as CCPs, to building products and ready mix concrete
companies. Headwaters purchases CCPs from coal-fired electric power generation plants under long-term contracts and supplies them to Headwaters customers as a replacement for manufactured or mined materials, primarily portland cement. CCP
revenues consist primarily of product sales with a small amount of service revenue.

The alternative energy segment includes
Headwaters legacy coal-based solid alternative fuels business and several newer initiatives, including coal cleaning, ethanol and the commercialization of catalyst technologies, primarily catalysts that help improve the yield and quality of
petroleum-based fuels. Revenues for this segment consist primarily of sales of chemical reagents and license fees.

The following segment
information has been prepared in accordance with SFAS No. 131, Disclosure about Segments of an Enterprise and Related Information. The accounting policies of the segments are described in Note 2. 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 alternative energy segment. Intersegment sales are immaterial.

Segment costs and expenses considered in deriving segment operating income 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. Segment information includes acquired subsidiaries results only for the periods subsequent to the dates
of acquisition, and therefore the information may not be comparable among all years presented.

million in 2007.

In accordance with the requirements of SFAS No. 142, Headwaters does not amortize goodwill,
all of which relates to acquisitions that occurred from 2001 through 2007. SFAS No. 142 requires Headwaters to periodically test for goodwill impairment at least annually, or more frequently if evidence of possible impairment arises. Headwaters
performs its annual impairment testing as of June 30, using a two-step process that begins with an estimation of the fair values of the reporting units that have goodwill. As of June 30, 2007, there were five reporting units with goodwill,
three of which were in the construction materials segment. There was one reporting unit with goodwill in each of the CCPs and alternative energy segments.

Step 1 of impairment testing consists of determining and comparing the fair values of the reporting
units to the carrying values of those reporting units. If step 1 is failed for a reporting unit, indicating a potential impairment, Headwaters is required to complete step 2, which is a more detailed test to calculate the implied fair value of
goodwill, and compare that value to the carrying value of the goodwill. If the carrying value of goodwill exceeds its implied fair value, an impairment loss is required to be recorded. Headwaters performed step 1 impairment tests of recorded
goodwill as of June 30, 2005, 2006 and 2007. With the exception of the Tapco reporting unit for 2007, all of the step 1 tests indicated that the fair values of the reporting units, calculated primarily using discounted expected future cash
flows, exceeded their carrying values. Accordingly, step 2 of the impairment tests was not required to be performed for those reporting units, and no impairment charges were necessary.

As a result of the depressed residential housing and remodeling market and changes in cost of capital, the Tapco reporting unit failed step 1 in 2007,
requiring completion of step 2, which resulted in a determination that Tapcos goodwill was impaired. Accordingly, a non-cash impairment charge of $98.0 million was recorded in 2007. The impairment did not affect Headwaters cash position,
cash flow from operating activities or senior debt covenants, and will not have any impact on future operations.

Senior Secured Credit AgreementsHeadwaters senior secured credit facility
currently consists of a first lien term loan in the amount of $210.0 million. The credit facility also provides for up to $60.0 million of borrowings under a 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 September 30, 2007.

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 loan for one, two, three or
six months. The weighted-average interest rate on the first lien debt was approximately 7.4% at September 30, 2007. Interest on the first lien term loan is generally payable on a quarterly basis.

In 2007, Headwaters issued $160.0 million of new convertible senior subordinated notes due 2014. Headwaters used most of the net proceeds from these
notes and available cash to repay $152.8 million of the first lien term loan. Headwaters also made another loan repayment of $52.5 million in 2007. As a result of these repayments, the remaining balance of the first lien term loan of $210.0 million
is repayable $84.8 million in February 2011 and $125.2 million in April 2011, the termination date. Due to the early repayments, Headwaters accelerated the amortization of related debt issue costs totaling approximately $2.6 million, which amount
was charged to interest expense. 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 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). There were no borrowings outstanding under the revolving credit
arrangement as of September 30, 2007, or subsequent thereto. The credit agreement also allows for the issuance of letters of credit, provided there is capacity under the revolving credit arrangement. As of September 30, 2007, six stand-by
letters of credit totaling approximately $6.0 million were outstanding, with expiration dates ranging from March 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 3.75:1.0 or less, declining to 3.5:1.0 in 2010; ii) a maximum ratio of consolidated funded indebtedness minus subordinated indebtedness to EBITDA of 2.75:1.0, declining to 2.5:1.0 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 1.25:1.0.

As required by the senior secured credit facility, Headwaters entered into agreements to limit its variable interest rate exposure through September 8, 2007. The agreements effectively fixed the LIBOR rate at
3.71% for $150.0 million of the first lien debt. Headwaters accounted for these agreements as cash flow hedges, with their fair market value reflected in the consolidated balance sheet as either other assets or other liabilities. Total comprehensive
income, considering all cash flow hedge agreements in which Headwaters was or is a party, was not materially different from net income for any period.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, continued

September 30, 2007



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 12). In January 2007, Headwaters announced
that it was planning an exchange offer for the 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, Headwaters announced that the commencement of an exchange offer had been indefinitely postponed. Headwaters continues to evaluate the merits of an exchange offer.

2.50% Convertible Senior Subordinated Notes Due 2014In 2007, Headwaters issued $160.0 million of 2.50% convertible senior subordinated notes due February 2014, with interest payable semi-annually. These
notes are subordinate to the senior secured debt and rank equally with the 2.875% convertible senior subordinated notes due 2016 described above, and any future senior subordinated debt. Total offering costs, including underwriting discounts and
commissions, were approximately $5.4 million. The conversion rate for the notes is 33.9236 shares per $1,000 principal amount ($29.48 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.
The net pre-tax cost of the hedge and warrant transactions was approximately $11.8 million. Because the contracts are indexed to Headwaters common stock and are not considered derivatives, the net cost was accounted for as a decrease in
paid-in capital. Headwaters also recorded a deferred tax asset of approximately $16.2 million related to the hedge transaction.

Notes
Payable to a BankThe notes payable to a bank were repaid in their entirety during 2007.

Interest and Debt
MaturitiesDuring 2005, Headwaters incurred total interest costs of approximately $59.7 million, including approximately $10.6 million of non-cash interest expense and approximately $0.5 million of interest costs that were
capitalized. During 2006, Headwaters incurred total interest costs of approximately $37.9 million, including approximately $2.8 million of non-cash interest expense and approximately $1.0 million of interest costs that were capitalized. During 2007,
Headwaters incurred total interest costs of approximately $35.0 million, including approximately $5.3 million of non-cash interest expense and approximately $0.8 million of interest costs that were capitalized. Interest income was approximately
$1.8 million, $2.9 million and $3.1 million for 2005, 2006 and 2007, respectively.

The weighted-average interest rate on the face
amount of outstanding long-term debt, disregarding amortization of debt issue costs, was approximately 5.7% at September 30, 2006 and 4.5% at September 30, 2007.

Future maturities of long-term debt as of September 30, 2007 were as follows:



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

9. Fair Value of Financial Instruments

Headwaters financial instruments consist primarily of cash and cash equivalents, trade receivables, accounts payable and long-term debt. All of
these financial instruments except long-term debt are either carried at fair value in the balance sheet or are short-term in nature. Accordingly, the carrying values for those financial instruments as reflected in the consolidated balance sheets
closely approximate their fair values.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, continued

September 30, 2007



Headwaters outstanding debt as of September 30, 2006 and 2007 consisted of both fixed-rate debt
and variable-rate debt. In 2006, the fixed-rate debt consisted of the 2.875% convertible senior subordinated notes due 2016 and the $150.0 million portion of variable-rate senior secured debt described in Note 8 for which Headwaters effectively
fixed the interest rate using cash flow hedges (through September 8, 2007). In 2007, the fixed-rate debt consisted of both issues of convertible senior subordinated notes. Using market interest rates for all fixed rate debt, the fair value of all
outstanding long-term debt as of September 30, 2006 and 2007 would have been approximately $600.4 million and $536.0 million, respectively, compared to carrying values of $595.1 million and $542.5 million, respectively.

Market rates used in 2006 to estimate fair value were approximately 2.8% for the 2.875% convertible senior subordinated notes due 2016 and 7.5% for the
$150.0 million portion of senior secured debt. Market rates used in 2007 were approximately 3.3% for the 2.875% convertible senior subordinated notes due 2016 and 3.1% for the 2.50% convertible senior subordinated notes due 2014. The market interest
rates for the convertible senior subordinated notes have changed from the stated interest rates primarily due to changes in Headwaters common stock price between the dates of issuance and the balance sheet measurement dates.

10. Income Taxes

Headwaters recorded income tax
provisions with an effective tax rate of approximately 26% in 2005 and 2006, and 66% in 2007 (24%, exclusive of the $98.0 million goodwill impairment charge, which is not tax-deductible). The effective tax rates are lower than statutory rates
primarily due to tax credits related to two coal-based solid alternative fuel facilities that Headwaters owns and operates, plus Headwaters 19% interest in an entity that owns and operates another alternative fuel facility (where Headwaters is
not the primary beneficiary). The alternative fuel produced at these three facilities through December 2007 qualifies for tax credits pursuant to Section 45K (formerly Section 29) of the Internal Revenue Code, subject to the uncertainties
of phase-out, IRS audit and other risks associated with the tax credits, all as more fully described in Note 14.

Headwaters 19%
interest in the entity that owns and operates an alternative fuel facility was acquired for payments totaling $15.5 million, of which $1.8 million remains to be paid as of September 30, 2007. This obligation is recorded in other accrued
liabilities in the consolidated balance sheet and bears interest at an 8% rate. Headwaters also agreed to make additional payments to the seller based on a pro-rata allocation of the tax credits generated by the facility through December 2007. These
additional contractual payments are affected by phase-out and, along with the amortization of the $15.5 million investment, are recorded in other expense in the consolidated statements of income, totaling approximately $16.1 million in 2005, $7.0
million in 2006 and $9.2 million in 2007. The alternative fuel produced at the facility through December 2007 qualifies for tax credits, and Headwaters is entitled to receive its pro-rata share of such tax credits generated based upon its
ownership percentage. Headwaters has the ability, under certain conditions, to limit its liability under the fixed payment obligations currently totaling approximately $1.8 million; therefore, Headwaters obligation to make all of the
above-described payments is effectively limited by the tax benefits Headwaters receives.

As a result of actual and projected oil prices
for calendar 2007, there will likely be a partial phase-out of Section 45K tax credits for the calendar year. In calculating an income tax provision for 2007, Headwaters used an estimated phase-out percentage for Section 45K tax credits of
54% for calendar 2007 (approximately 70% calculated as of October 31, 2007). This estimated phase-out percentage was derived by estimating the calendar 2007 reference price for oil using actual oil prices for January through July 2007 and
published NYMEX oil prices for the months August through December 2007. The monthly NYMEX oil prices were reduced by approximately 10%, which reduction represents Headwaters estimate of the relationship between NYMEX oil prices and the average
U.S. wellhead oil prices actually used to calculate the annual reference price. The



F-19

##### Table of Contents

HEADWATERS INCORPORATED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, continued

September 30, 2007



reference price for calendar 2007 was calculated by averaging the 12 months actual or estimated oil prices, which average was compared to the estimated
phase-out range for calendar 2007 of $56.16 to $70.50 to derive an estimated phase-out percentage. Headwaters estimates that NYMEX average oil prices would need to exceed $110 for the period October 1, 2007 through December 31, 2007 for
full phase-out to occur in calendar 2007.

While the calendar 2007 phase-out percentage can not be finalized at the current time, as of
September 30, 2007, the estimated phase-out percentage represents Headwaters best estimate of what the phase-out percentage would be, using available information as of that date. The effect on income taxes of any change in the calendar
2007 phase-out percentage from 54% to the actual percentage for the year will be recorded to income tax expense in subsequent periods, when the calendar 2007 actual oil prices and the phase-out range are known. Any such effect could be material to
Headwaters 2008 income tax expense.

The income tax provision consisted of the following for the years ended September 30:

The calculation of tax liabilities involves uncertainties in the application of complex tax
regulations in multiple jurisdictions. For example, Headwaters is currently under IRS audit for 2005 and 2006 and the IRS audit for 2003 and 2004 is not yet finalized. Headwaters recognizes potential liabilities for anticipated tax audit issues in
the U.S. and state tax jurisdictions based on estimates of whether, and the extent to which, additional taxes and interest will be due. If events occur and the payment of these amounts ultimately proves to be unnecessary, the

reversal of the liabilities would result in tax benefits being recognized in the period when it is determined the liabilities are no longer probable or
necessary. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result.

As
of September 30, 2007, Headwaters had deferred tax assets related to U.S., state and non-U.S. net operating loss (NOL) and capital loss carryforwards totaling approximately $5.1 million. Headwaters has established a valuation
allowance for substantially all of this amount. A valuation allowance is required when there is significant uncertainty as to the realizability of deferred tax assets. Because the realization of the deferred tax assets related to these NOLs and
capital losses is dependent upon future income or capital gains related to domestic and foreign jurisdictional operations that have historically generated losses, management determined that it is not more likely than not that these NOLs
and capital losses will be realized and therefore, a valuation allowance is required. The U.S. and state NOLs and capital losses expire from 2010 to 2027. Substantially all of the non-U.S. NOLs do not expire.

The components of Headwaters deferred income tax assets and liabilities were as follows as of September 30:

costs totaling $11.6 million. Approximately $18.0 million remains available for future offerings of securities under a universal shelf registration statement
filed in connection with the common stock offering. A prospectus supplement describing the terms of any additional securities to be issued is required to be filed before any future offering would commence under the registration statement.

Grants of Stock Incentive AwardsDuring 2005, the Compensation Committee of Headwaters Board of Directors (the
Committee) granted to certain officers and employees stock incentive awards consisting of approximately 3.0 million stock appreciation rights (SARs) and approximately 0.2 million stock options. Approximately
2.0 million of the SARs vested at grant date, a majority of which required a payment by grantees of $2.00 per SAR, payable over a 52-month period. Also, the maximum gain that could have been received for each of those SARs was limited to the
fair market value of one share of Headwaters common stock at the date of grant. The grant of those immediate-vested SARs resulted in approximately $16.2 million of compensation expense being recorded in 2005, which was calculated in accordance
with SFAS No. 123R as described below under Stock-Based Compensation. The remaining SARs which were granted during 2005 (approximately 1.0 million) had five-year vesting terms, and approximately 0.9 million of those SARs
were exercisable based on the achievement of performance criteria related to the economic growth of Headwaters during the five-year vesting period. In 2007, the officers and employees who received the 2005 SAR grants agreed to voluntarily cancel
substantially all of the SARs, including all of the immediate-vested SARs and all of the performance-based SARs.

During 2006, the
Committee granted i) options for the purchase of approximately 0.1 million shares of common stock to certain directors, and ii) approximately 0.2 million SARs to certain employees. During 2007, the Committee granted approximately
0.2 million SARs to certain employees. Subsequent to September 30, 2007, the Committee granted approximately 1.0 million stock-based awards to certain directors, officers and employees. All stock-based awards for the years 2005
through 2007 and subsequent thereto were granted under existing stock incentive plans, and all have an exercise price equal to the fair market value of Headwaters common stock on the dates of grant and a contractual term of 10 years. When
exercised by grantees, SARs are settled in Headwaters common stock.

In 2005, the Committee also approved the acceleration of vesting
of options for the purchase of approximately 1.1 million shares for 138 officers, directors and employees which were not fully vested as of the date of acceleration (prior to acceleration, there were in total unvested outstanding options to
purchase approximately 1.3 million shares). Options for which vesting was accelerated consisted of all options with an exercise price equal to or greater than $21.29 per share and all but approximately 0.2 million of the accelerated
options were in the money at the date of acceleration. Of the options accelerated, options to purchase a total of approximately 0.5 million shares of common stock were granted to directors and executive officers of Headwaters. All
of the options for which acceleration of vesting occurred became 100% vested as of the date of acceleration. Total compensation expense of approximately $9.3 million was recognized related to the acceleration of vesting.

Stock-Based CompensationDuring 2005, Headwaters early adopted SFAS No. 123R
effective as of October 1, 2004, the beginning of Headwaters 2005 fiscal year (the modified retrospective method, with restatement limited to interim periods in the year of adoption, as permitted by SFAS No. 123R). SFAS
No. 123R revised SFAS No. 123 and superseded APB 25 and requires companies to expense the value of employee stock options and other equity-based awards. The following table summarizes stock-based compensation included in cost of revenue
and operating expenses for the years indicated.

A significant amount of the 2005 stock-based compensation resulted from the expense associated
with the grants of immediate-vested SARs and from the acceleration of vesting of certain stock options. Approximately $3.9 million of the 2007 stock-based compensation resulted from the early voluntary cancellation of SARs and other stock-based
awards, requiring an acceleration of expense recognition for unrecognized compensation cost that remained as of the cancellation dates. The total income tax benefit recognized for stock-based compensation in the consolidated income statements was
approximately $12.2 million, $2.5 million and $0.5 million for 2005, 2006 and 2007, respectively.

Valuation AssumptionsThe
fair values of stock options and SARs were estimated using the B-S-M model, adjusted where necessary to account for specific terms of awards that the B-S-M model does not have the capability to consider. Headwaters used the services of an
independent valuation firm to validate its fair value estimates and assumptions and also to determine certain necessary adjustments to the B-S-M model output. One such adjustment was used in determining the fair value of SARs which have a cap on
allowed appreciation. For these SARs, the output determined by the B-S-M model was reduced by an amount determined by a Quasi-Monte Carlo simulation to reflect the reduction in fair value associated with the appreciation cap.

The following table summarizes the assumptions used in determining the fair values of stock-based awards.

Expected stock price volatility was estimated using primarily historical volatilities of
Headwaters stock. Implied volatilities of traded options on Headwaters stock, volatility predicted by a Generalized AutoRegressive Conditional Heteroskedasticity model, and an analysis of volatilities used by other public
companies in comparable lines of business to Headwaters were also considered. Risk-free interest rates used were the US Treasury bond yields with terms corresponding to the expected terms of the awards being valued. In

estimating expected lives, Headwaters considered the contractual and vesting terms of awards, along with historical experience; however, due to insufficient
historical data from which to reliably estimate expected lives, Headwaters used estimates based on the simplified method set forth by the SEC in Staff Accounting Bulletin No. 107, where expected life is estimated by summing the
awards vesting term and the contractual term and dividing that result by two. The reduction in value related to grantee payment for certain immediate-vested SARs was estimated by management based on the terms of the payment requirements and
other factors.

Stock Incentive PlansAs of September 30, 2007, Headwaters had four stock incentive plans (the
Plans), three of which have been approved by stockholders. A total of 7.9 million shares of common stock have been reserved for ultimate issuance under the Plans. One of the Plans has expired and awards can no longer be granted
under that plan. As of September 30, 2007, options, SARs and other awards for approximately 2.5 million shares of common stock could be granted under the three remaining plans. Headwaters uses newly issued shares to meet its obligations to
issue stock when awards are exercised. The Committee, or in its absence, the full Board, administers and interprets the Plans. This Committee is authorized to grant options and other awards both under the Plans and outside of any Plan to eligible
employees, officers, directors, and consultants of Headwaters. Terms of options and other awards granted under the Plans, including vesting requirements, are determined by the Committee and historically have varied significantly. Options and other
awards granted under the Plans vest over periods ranging from zero to ten years, expire ten years from the date of grant and are not transferable other than by will or by the laws of descent and distribution. Incentive stock option grants must meet
the requirements of the Internal Revenue Code.

Stockholder Approval of Equity Compensation PlansThe following table presents
information related to stockholder approval of equity compensation plans as of September 30, 2007.

As discussed above, Headwaters has four Plans under which options and SARs have been granted and
stockholders have approved three of the four Plans. Headwaters has also issued options not covered by any Plan. The amounts included in the caption not approved by stockholders in the above table represent amounts applicable under the
Plan not approved by stockholders plus all awards granted outside of any Plan.

The weighted-average grant-date fair value of SARs granted was $9.65, $14.04 and $9.87 in 2005,
2006 and 2007, respectively. The total intrinsic value of SARs exercised was approximately $0.1 million in 2005 and 2006 and $0 in 2007.

Other Stock-Based Awards and Unrecognized Compensation CostIn addition to the stock options and SARs reflected in the tables above, Headwaters has issued less than 0.1 million shares of restricted common stock to officers
and employees. The restricted stock was issued at no cost to the recipients and vests over periods ranging from two to five years. Compensation expense equal to the value of the stock on the date of grant is recognized over the vesting periods which
also represent the requisite service periods. In 2005, Headwaters agreed to issue up to 25,000 shares of common stock to the Chief Executive Officer and Chairman of the Board, which shares would have vested in March 2010 if the market value of a
share of Headwaters common stock met or exceeded stipulated thresholds. The fair value of this contingent performance stock was estimated by an independent valuation firm by calculating the probabilities that Headwaters
common stock would reach the various market value thresholds. The fair value was being recognized as expense over the requisite service period, or through March 2010; however, this award was voluntarily cancelled in 2007, at which time the
unrecognized grant-date fair value that had not been recognized as of the cancellation date was charged to expense. Finally, Headwaters also recognizes compensation expense in connection with its Employee Stock Purchase Plan (ESPP).
Compensation expense related to restricted stock, contingent performance stock and the ESPP was not material.

As of September 30,
2007, there was approximately $2.9 million of total compensation cost related to nonvested awards not yet recognized. This unrecognized compensation cost is expected to be recognized over a

weighted-average period of approximately 1.9 years. Due to the grant of stock-based awards subsequent to September 30, 2007 described above, the amount
of total compensation cost related to nonvested awards has increased, and the weighted-average period over which compensation cost will be recognized has changed.

SFAS No. 123R changed the method of applying the treasury stock method in determining the
potential dilutiveness of stock-based awards for diluted EPS calculations. In accordance with the requirements of SFAS No. 123R, the EPS calculations above considered all of the following as assumed proceeds in using the treasury stock method
to calculate whether and to what extent options and SARs were dilutive: i) the amounts employees must pay upon exercise; plus ii) the average amount of compensation cost during the period, if any, attributed to future service, but not yet
recognized; plus iii) the amount of tax benefits, if any, that would be credited to additional paid-in capital if the award were to be exercised. In addition to the anti-dilutive securities listed above, the shares issuable upon conversion of
Headwaters 2.875% convertible senior subordinated notes due June 2016 were also anti-dilutive for 2007 and were therefore omitted from the diluted EPS calculation.

13. Acquisitions

During 2006, Headwaters acquired certain assets and assumed certain liabilities of
several privately-held companies in the construction materials industry. Total consideration paid or accrued for these acquisitions was less than $8.0 million. 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.

In 2007, Headwaters acquired 100% of the ownership interests of a privately-held company in the construction materials business. Total consideration paid
at the date of acquisition, of approximately $53.0 million, consisted primarily of cash. An additional amount, currently estimated to be approximately $20.0 million, is payable in the future, based on earnings of the acquired entity for
the 12 month period ended September 30, 2007 that exceed an agreed-upon threshold.

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

14. Commitments and Contingencies

Commitments and
contingencies as of September 30, 2007 not disclosed elsewhere, are as follows.

LeasesRental expense was approximately
$24.3 million, $30.9 million and $34.4 million in 2005, 2006 and 2007, respectively. Headwaters has noncancellable operating leases for certain facilities and equipment. Most of these leases have renewal terms and currently are set to expire in
various years through 2017. As of September 30, 2007, minimum rental payments due under these leases are as follows.

Purchase CommitmentsCertain CCP segment contracts with suppliers require Headwaters
to make minimum purchases. Actual purchases under contracts with minimum requirements were approximately $13.2 million, $15.4 million and $14.0 million for 2005, 2006 and 2007, respectively. As of September 30, 2007, minimum future
requirements are as follows.

Compensation ArrangementsEmployment Agreements. Headwaters and its
subsidiaries have entered into employment agreements with its Chief Executive Officer and several other officers and employees. The

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, continued

agreements have original terms ranging up to five years, many of which are renewable by Headwaters, often for one-year terms. They provide for annual
salaries currently ranging from approximately $0.1 million to $0.7 million annually per person. Assuming all agreements set to expire in 2008 are renewed, the annual commitment under all employment agreements combined would currently
approximate $2.9 million. The aggregate commitment as of September 30, 2007, assuming no renewals, is approximately $4.4 million. Most agreements provide for termination benefits, which vary widely from agreement to agreement.

Long-Term Incentive Cash Bonus Awards.In 2006, Headwaters Compensation Committee (the Committee) authorized the grant of
long-term incentive cash bonus awards to certain officers and employees, which awards were granted under Headwaters Long Term Incentive Compensation Plan. In accordance with terms of the awards, cash payments are based on several factors,
including the achievement of stipulated financial goals as measured by economic value added (EVA) over a three-year period by Headwaters and its operating units. Payments for these awards may not exceed $30.0 million in the aggregate.
Approximately $1.1 million has been accrued for these awards through September 30, 2007.

Executive Change in Control
Agreements. In 2006, the Committee also approved Executive Change in Control Agreements with certain officers. Upon a change in control, as defined, the agreements provide for immediate vesting and exercisability of all outstanding
stock awards. In addition, if termination of employment occurs within a specified period of a change in control, the agreements provide for i) severance pay equal to two times the sum of an officers current annual salary plus the highest cash
bonus paid or payable for any single year in the three-year period commencing two years prior to the year in which the change in control occurs; and ii) continuance of health and other benefits and perquisites for a two-year period following the
change in control. If terminations associated with a change in control would have occurred on September 30, 2007, the severance payments due to the officers would have aggregated approximately $21.2 million.

Performance Unit Awards.In 2005 the Committee authorized the grant of performance unit awards, to be settled in cash, based on performance
criteria tied to the economic value created or preserved by one of Headwaters business units after December 2007. The grants of these performance units were made in 2006 and could result in the payment to employees of a maximum amount of
approximately $3.8 million if all performance criteria are met. No amounts have been expensed for these awards through September 30, 2007 because it is not yet probable that the performance criteria will be met.

Contingent Commission Agreement. In addition to its standard sales commission arrangements, Headwaters has entered into a contingent
commission agreement whereby it has agreed to pay an employee total sales commissions up to a maximum amount of $4.5 million. The agreement calls for payments to be made for customer purchase orders of a stipulated size and for a stipulated
period of time to be executed prior to May 2008. No amounts have been required to be expensed under this agreement through September 30, 2007.

Employee Benefit PlansIn addition to standard health and life insurance programs, Headwaters has five employee benefit plans that were operative during the three-year period ended September 30, 2007: the 401(k) Profit
Sharing Plan (401(k) Plan), the 2000 Employee Stock Purchase Plan (ESPP), the Incentive Bonus Plan (IBP), the Deferred Compensation Plan (DCP) and the Long Term Incentive Compensation Plan
(LTIP). Substantially all employees of Headwaters are eligible to participate in the 401(k) Plan and the ESPP after meeting length of service requirements. Only designated employees are eligible to participate in the IBP, DCP and LTIP.

The total expense for all of Headwaters benefit plans combined (excluding standard health and life insurance programs and ESPP
expense, which is included in stock-based compensation, and including all general

and discretionary bonuses paid outside of the IBP) was approximately $22.8 million, $16.4 million and $23.0 million in 2005, 2006 and 2007,
respectively.

401(k) Plan. Under the terms of the 401(k) Plan, eligible employees may elect to make tax-deferred contributions of
up to 50% of their compensation, subject to statutory limitations. Headwaters matches employee contributions up to a designated maximum rate and these matching contributions vest after three years. Headwaters is not required to be profitable to make
matching contributions.

ESPP. The ESPP provides eligible employees with an opportunity to purchase Headwaters common stock on
favorable terms and to pay for such purchases through payroll deductions. A total of 500,000 shares of common stock were initially reserved for issuance under the Plan, and approximately 32,000 shares remain available for future issuance as of
September 30, 2007. In accordance with terms of the ESPP, participating employees purchase shares of stock directly from Headwaters, which shares are made available from treasury shares which have been repurchased on the open market. The ESPP
is intended to comply with Section 423 of the Internal Revenue Code, but is not subject to the requirements of ERISA. Employees purchase stock through payroll deductions of 1% to 10% of cash compensation, subject to certain limitations. The
stock is purchased in a series of quarterly offerings. The cost per share to the employee is 85% of the fair market value at the end of each offering period.

IBP. The IBP, the specifics of which are approved annually by the Committee, provides for annual cash bonuses to be paid if Headwaters accomplishes certain financial goals and if participating employees meet
individual goals. In the past, Headwaters financial goals have been based upon an economic value added concept (EVA) that purports to more closely align with a companys share price performance than other measurements of
performance. The Committee has approved the use of other performance measurements for periods beginning October 1, 2007.

DCP.
The DCP is a nonqualified plan that allows eligible employees to make tax-deferred contributions of up to 50% of their base compensation and 100% of their incentive compensation. In certain instances, Headwaters matches employee contributions up to
a designated maximum rate and these matching contributions vest after three years. Headwaters is not required to be profitable to make matching contributions.

LTIP. Other than obligations associated with the long-term incentive cash bonus awards described above and grants of certain of the stock-based awards described in Note 11, Headwaters has no commitments under
the LTIP as of September 30, 2007.

Self InsuranceHeadwaters has adopted self-insured medical insurance plans that cover
substantially all employees. There is stop-loss coverage for amounts in excess of $100,000 to $200,000 per individual per year. Headwaters also self insures for workers compensation claims in most states, limited by stop-loss coverage for amounts in
excess of $250,000 per occurrence and approximately $6.0 million in the aggregate annually. Headwaters has contracted with third-party administrators to assist in the payment and administration of claims. Insurance claims are recognized as expense
when incurred and include an estimate of costs for claims incurred but not reported at the balance sheet date. As of September 30, 2007, approximately $6.0 million is accrued for medical and workers compensation claims incurred on or before
September 30, 2007 that have not been paid or reported.

Property, Plant and EquipmentAs of September 30, 2007,
Headwaters was committed to spend approximately $37.6 million on capital projects that were in various stages of completion.

Joint Venture ObligationHeadwaters has entered into various joint ventures with Evonik
Industries AG (formally Degussa AG), an international chemical company based in Germany. One of these joint ventures purchased a hydrogen peroxide business located in South Korea. Headwaters is a principal obligor with respect to all non-financial
obligations of the joint venture and, with respect to financial obligations of the joint venture, 50% of future plant expansion cost overruns, if any.

Legal or Contractual 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. In 2007, Headwaters incurred approximately $3.4 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 September 30, 2007 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.

McEwan. In 1995, Headwaters granted stock options to a member of its board of directors, Lloyd McEwan. The director resigned from the board in
1996. Headwaters declined McEwans attempts to exercise most of the options on grounds that the options terminated. In June 2004, McEwan filed a complaint in the Fourth District Court for the State of Utah against Headwaters alleging breach of
contract, breach of implied covenant of good faith and fair dealing, fraud, and misrepresentation. The complaint sought declaratory relief as well as compensatory damages in the approximate amount of $2.8 million and punitive damages. Headwaters
filed an answer denying McEwans claims and asserted counterclaims against McEwan. In 2007, the parties agreed to settle the case. Headwaters paid McEwan approximately $0.1 million and all claims of the parties will be dismissed with prejudice.

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 between $15.0 million and $25.0 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 Construction Materials Matters.There are litigation and pending and threatened claims made against certain subsidiaries of Headwaters
Construction Materials (HCM) 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 Best Masonry & Tool
Supply and Dons Building Supply. 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 been derived from license fees and
sales of chemical reagents, both of which depend on the ability of licensees and

September 30, 2007



other customers to manufacture and sell qualified synthetic fuel that generates 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 owns an interest (see Note 10). The following issues exist related to tax credits.

Termination of Section 45K. By law, Section 45K tax credits for synthetic fuel produced from coal expire for synthetic fuel sold after
December 31, 2007. When Section 45K expires at the end of calendar 2007, Headwaters expects its licensees synthetic fuel facilities to close because Headwaters does not believe that production of synthetic fuel will be profitable
absent the tax credits. When Headwaters licensees close their facilities or significantly reduce production activities, it will have a material adverse effect on the revenue, net income and cash flow of Headwaters, in addition to the current
material adverse effect caused by phase-out concerns, discussed below.

Phase-Out. Section 45K tax credits are subject to
phase-out after the average annual U.S. wellhead oil price (reference price) reaches a beginning phase-out threshold price, and are eliminated entirely if the reference price reaches the full phase-out price. In recent periods, the
reference price has been approximately 90% of the published market prices for oil. For calendar 2006, the reference price was $59.69 per barrel and the phase-out range began at $55.06 and would have fully phased out tax credits at $69.12 per barrel.
Therefore, there was a partial phase-out of tax credits for calendar 2006 of approximately 33%.

For calendar 2007, Headwaters estimates
that the phase-out range (computed by increasing the 2006 inflation adjustment factor by 2%) begins at $56.16 and completes phase-out at $70.50 per barrel. As described in more detail in Note 10, Headwaters estimated a phase-out percentage for
Section 45K tax credits for calendar 2007 of 54%, using available information as of September 30, 2007. It is certain that the phase-out percentage for calendar 2007 will be different from this estimate. Headwaters estimates that NYMEX
average oil prices would need to exceed $110 for the period October 1, 2007 through December 31, 2007 for full phase-out to occur in calendar 2007.

In an environment of high oil prices, the risk of phase-out increases. Headwaters customers and licensees make their own assessments of phase-out risk. When customers and licensees have perceived a potential
negative financial impact from phase-out, they have reduced or stopped synthetic fuel production or required Headwaters to share in the costs associated with phase-out. Headwaters makes similar assessments with respect to the continued operation of
its own synthetic fuel production facilities. Most of Headwaters licensees stopped production for a period of time in calendar 2006. As of September 30, 2007, all of Headwaters licensees were producing synthetic fuel, but some have
indicated intent to stop production prior to December 31, 2007. These events have materially adversely affected both the amount and timing of recognition of Headwaters revenue, net income and cash flow in 2006 and 2007, and will likely
have a material adverse effect in 2008, until Section 45K expires.

The amount of license fee revenue recognized by Headwaters during
2006 and 2007 was negatively affected by reduced revenues being recognized for certain licensees whose license agreements call for Headwaters to be paid a portion of the tax credits earned by the licensee. Certain accounting rules limit revenue
recognition to amounts that are fixed or determinable. Therefore, due to uncertainties related to phase-out and other licensee-specific factors, the timing of revenue recognition was delayed for certain licensees during fiscal 2006 and
2007.

Due to publication of the calendar 2006 reference price and the phase-out range for that year, finalization of calendar 2006
phase-out was made possible during the quarter ended June 30, 2007. As a result of the availability

September 30, 2007



of this information and the clarification of other licensee-specific factors, certain calendar 2006 and prior year license fee revenue totaling approximately
$31.5 million was recognized in 2007. This amount related to periods ending on or prior to December 31, 2006 and was recognized in 2007 when it met the fixed or determinable recognition criterion and it was remote that any negative
adjustment would be required in the future. Headwaters has applied the same policy in 2007 with regard to the recognition of revenue for calendar 2007 tax credit-based license fees. The final determination of revenue to be collected pertaining to
fiscal and calendar year 2007 will not occur until the calendar 2007 reference price and phase-out range are published in the quarter ending June 30, 2008.

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. The inability of a licensee to claim Section 45K tax credits would reduce Headwaters future income from the licensee. In addition, the IRS may audit Headwaters tax credits claimed for synthetic fuel sold from
the facilities in which it owns an interest.

15. Related Party Transactions

In addition to transactions disclosed elsewhere, Headwaters was involved in the following transactions with related parties. A director of Headwaters is a
principal in one of the insurance brokerage companies Headwaters uses to purchase certain insurance benefits for its employees. Commissions paid to that company by providers of insurance services to Headwaters totaled approximately $0.2 million in
2005, 2006 and 2007.

One of Headwaters subsidiaries purchases product from an entity located in Mexico in which a person who was an
officer of Headwaters until November 2007 has a minority ownership interest. Costs incurred for materials purchased from this entity were approximately $11.8 million, $16.2 million and $14.6 million in 2005, 2006 and 2007, respectively. A
majority of another subsidiarys transportation needs are provided by a company, two of the principals of which are related to an officer of the subsidiary. Costs incurred were approximately $4.9 million, $5.9 million and $5.7 million in
2005, 2006 and 2007, respectively.

|(1) | In all periods, the amount of revenue recognized for tax credit-based license fees was significantly affected by the fixed or determinable accounting rules for revenue
recognition (see Note 14).

|(2) | In accordance with SFAS No. 128, Earnings Per Share, EPS is computed independently for each of the four fiscal quarters in a year. In 2007, diluted EPS computed for
the year does not equal the sum of the four quarterly computations. This situation arose primarily because Headwaters 2.875% convertible senior subordinated notes due June 2016 were dilutive in the first three quarters of 2007 and were
therefore included in computing diluted EPS, but were anti-dilutive in the fourth quarter and for the year and were therefore excluded in computing diluted EPS.

|(3) | In the fourth quarter of 2006, Headwaters recorded income tax expense at a tax rate of approximately 11%, compared to an effective income tax rate of approximately 30% for the first
three quarters of the year. The lower rate for the fourth quarter was required to reduce the income tax rate for the year to approximately 26% as a result of changes in the estimated phase out of Section 45K tax credits (see Note 10).
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(4) | In the fourth quarter of 2007, Headwaters recorded income tax expense of $12.8 million even though there was a loss before income taxes of $57.8 million. This resulted primarily
from the non-tax deductibility of the $98.0 goodwill impairment charge recorded in that quarter (see Notes 7 and 10). The estimated effective tax rate used to record income tax expense (prior to the consideration of discrete items) for the first
three quarters was 23%. The effective tax rate for the year was 66%.
