CALCULATION OF REGISTRATION FEE

(1)

Pursuant to Rule 429 under the Securities Act, this registration statement contains a combined prospectus that also relates to securities previously registered under a registration statement (Commission File No. 333-125652) of Huntsman International LLC and certain of the additional registrants. The prior registration statement was declared effective on July 28, 2005. The filing fee associated with such securities was previously paid with that registration statement.

(2)

Pursuant to Rule 457(n) under the Securities Act, no separate fee is payable with respect to the guarantees of the new notes being registered.

        The Registrants hereby amend this registration statement on such date or dates as may be necessary to delay its effective date until the Registrants shall file a further amendment that specifically states that this registration statement shall thereafter become effective in accordance with Section 8(a) of the Securities Act or until this registration statement shall become effective on such date as the Securities and Exchange Commission, acting pursuant to said Section 8(a), may determine.

Explanatory Note

        Certain of the registrants filed a registration statement on Form S-4 (Commission File No. 333-125652). The prior registration statement was declared effective on July 28, 2005. Huntsman International LLC subsequently entered into transactions which resulted in the addition of guarantors. Pursuant to Rule 413(a) under the Securities Act, the registration of additional guarantors is not permitted to be effected through a post-effective amendment to the prior registration statement. Pursuant to Rule 429 under the Securities Act, this registration statement contains a combined prospectus and shall act, upon effectiveness, as a post-effective amendment to the prior registration statement.

Explanatory Note

        On July 29, 2005, we commenced the exchange offer. The exchange offer was scheduled to expire at 5:00 p.m., New York City time, on August 26, 2005. On August 16, 2005, however, Huntsman LLC merged into our Company (the "HLLC Merger") and Huntsman International Holdings LLC ("HIH") also merged into our Company (collectively with the HLLC Merger, the "HLLC/HIH Mergers"). As a result of the HLLC/HIH Mergers, pursuant to applicable rules of the Securities and Exchange Commission (the "Commission" or the "SEC"), we were required not to make an offering until we had filed certain additional financial statements with the Commission. Accordingly, we temporarily suspended the exchange offer and caused all tendered old notes to be returned to the holders thereof.

        During this temporary suspension period, on December 20, 2005, Huntsman Corporation agreed to pay $125 million to affiliates of SISU Capital Limited and other third parties to acquire the 9.7% of the equity of Huntsman Advanced Materials Holdings LLC ("AdMat") that it did not already own. In conjunction with this acquisition, we amended our senior secured credit facilities and increased our existing term loan by $350 million. We used proceeds from the increased term loan, together with approximately $74 million of cash on hand, to acquire the 9.7% interest in AdMat, to redeem AdMat's $250 million of outstanding 11% senior secured notes due 2010, to pay $35.6 million in call premiums plus accrued interest and to pay other related costs, and Huntsman Corporation then contributed its 100% ownership interest in AdMat to us (the "AdMat Minority Interest Transaction"). Accordingly, AdMat and its subsidiaries have become our subsidiaries. As a result of the AdMat Minority Interest Transaction, pursuant to applicable rules of the Commission, we were required not to make an offering until we had filed certain additional financial statements with the Commission.

        We have now filed the required additional financial statements with the Commission in connection with the HLLC/HIH Mergers and the AdMat Minority Interest Transaction and will recommence the exchange offer in accordance with the terms set forth in this prospectus.

ii

        Each broker-dealer that receives new notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of the new notes it receives. The letter of transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act of 1933, as amended. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of new notes received in exchange for old notes where such old notes were acquired by the broker-dealer as a result of market-making activities or other trading activities. We have agreed that, for a period of 120 days after the consummation of the exchange offer, we will make this prospectus, as amended and supplemented, available to any broker-dealer for use in connection with any such resale. See "Plan of Distribution."

SUSPENSION AND RECOMMENCEMENT OF EXCHANGE OFFER

        On July 29, 2005, we commenced the exchange offer to which this prospectus relates. The exchange offer was scheduled to expire at 5:00 p.m., New York City time, on August 26, 2005. On August 16, 2005, however, we completed the HLLC/HIH Mergers and, pursuant to applicable rules of the Commission, we were required not to make an offering until we had filed certain additional financial statements with the Commission. Accordingly, we temporarily suspended the exchange offer and caused all tendered old notes to be returned to the holders thereof. During this suspension period, we also completed the AdMat Minority Interest Transaction and, pursuant to applicable rules of the Commission, were required to file certain additional financial statements with the Commission. We have now filed the required additional financial statements in connection with each of the HLLC/HIH Mergers and the AdMat Minority Interest Transaction.

        We have accounted for the HLLC/HIH Mergers and the AdMat Minority Interest Transaction as an exchange of shares between entities under common control, similar to a pooling of interests, and, as required, we have restated our financial statements to reflect the HLLC/HIH Mergers and the AdMat Minority Interest Transaction. Huntsman LLC and AdMat came under common control with us effective May 1, 2003 and June 30, 2003, respectively. HIH and our Company have been under common control since our inception. The financial data presented herein reflect the financial position, results of operations and cash flows as if HIH, Huntsman LLC, AdMat and our Company were combined for all periods for which they were under common control. Accordingly, this prospectus includes:

•

our audited financial statements giving effect to the HLLC/HIH Mergers and the AdMat Minority Interest Transaction;



•

management's discussion and analysis of financial condition and results of operations giving effect to the HLLC/HIH Mergers and the AdMat Minority Interest Transaction for the periods covered by the audited financial statements; and



•

selected financial data for the five most recent years giving effect to the HLLC/HIH Mergers and the AdMat Minority Interest Transaction.

        We will recommence the exchange offer in accordance with the terms set forth in this prospectus. In order to participate in the exchange offer (whether or not you previously tendered your old notes), you must now comply with the requirements set forth in this prospectus, including the requirements specified in "The Exchange Offer—Terms of the Exchange Offer" on page 27.

PROSPECTUS SUMMARY

        The following summary highlights selected information from this prospectus and may not contain all the information that is important to you. This prospectus contains information regarding our business and detailed financial information. You should carefully read this entire document.

        Unless the context otherwise requires, references in this prospectus to "we," "us," "our" or our "Company" refer to Huntsman International LLC, together with its subsidiaries. In this prospectus, "HIH" refers to Huntsman International Holdings LLC, "Huntsman LLC" or "HLLC" refers to Huntsman LLC, and, unless the context otherwise requires, its subsidiaries, and "AdMat" refers to Huntsman Advanced Materials Holdings LLC and, unless the context otherwise requires, its subsidiaries.

        Information about our business and operations refers to the combined business and operations of our Company, Huntsman LLC and AdMat after giving effect to the HLLC/HIH Mergers and the AdMat Minority Interest Transaction discussed in "—Our Company—History" below. The HLLC/HIH Mergers and the AdMat Minority Interest Transaction have been accounted for as an exchange of shares between entities under common control, similar to a pooling of interests. Huntsman LLC and AdMat came under common control with us effective May 1, 2003 and June 30, 2003, respectively. HIH and our Company have been under common control since our inception. The financial data presented herein reflect the financial position, results of operations and cash flows as if HIH, Huntsman LLC, AdMat and our Company were combined for all periods for which they were under common control. As a result, the financial information as of and for the years ended December 31, 2003, 2002 and 2001 is not comparable to the financial information as of and for the years ended December 31, 2005 and 2004.

Our Company

History

        We are a Delaware limited liability company and all of our membership interests are owned by Huntsman Corporation. We were formed in 1999 in connection with a transaction between HIH, Huntsman Specialty Chemicals Corporation ("Huntsman Specialty") and Imperial Chemical Industries PLC ("ICI"). In that transaction, on June 30, 1999, HIH acquired ICI's polyurethane chemicals, selected petrochemicals and titanium dioxide ("TiO₂" or "Tioxide") businesses and Huntsman Specialty's propylene oxide ("PO") business. HIH also acquired the 20% ownership interest of BP Chemicals Limited in an olefins facility located at Wilton, U.K. and certain related assets. HIH then transferred the acquired businesses to us and to our subsidiaries.

        On August 16, 2005, Huntsman LLC, another wholly-owned subsidiary of Huntsman Corporation, merged into our Company and we continued in existence as the surviving entity (the "HLLC Merger"). At that time, HIH also merged into our Company (collectively with the HLLC Merger, the "HLLC/HIH Mergers"). Prior to the HLLC/HIH Mergers, all of our membership interests were owned by HIH, and HIH was owned 58% by Huntsman Corporation and 42% by Huntsman LLC.

        On December 20, 2005, Huntsman Corporation agreed to pay $125 million to affiliates of SISU Capital Limited and other third parties to acquire the 9.7% of the equity of AdMat that it did not already own. In conjunction with this acquisition, we amended our senior secured credit facilities and increased our existing term loan by $350 million. We used proceeds from the increased term loan, together with approximately $74 million of cash on hand, to acquire the 9.7% interest in AdMat, to redeem AdMat's $250 million of outstanding 11% senior secured notes due 2010, to pay $35.6 million in call premiums plus accrued interest, and to pay other related costs, and Huntsman Corporation then contributed its 100% ownership interest in AdMat to us (the "AdMat Minority Interest Transaction"). As a result, AdMat and its subsidiaries have become our subsidiaries. We did not pay any consideration to Huntsman Corporation in connection with the AdMat Minority Interest Transaction other than the issuance of additional equity to Huntsman Corporation.

1

        Huntsman Corporation effected the HLLC/HIH Mergers and the AdMat Minority Interest Transaction to simplify its consolidated group's financing and public reporting structure, to reduce its cost of financing and to facilitate other organizational efficiencies. The HLLC/HIH Mergers and the AdMat Minority Interest Transaction were accounted for as an exchange of shares between entities under common control similar to the pooling method.

        Prior to the HLLC/HIH Mergers and the AdMat Minority Interest Transaction, we operated our businesses through four segments: Polyurethanes, Performance Products, Pigments and Base Chemicals. Huntsman LLC was a manufacturer and marketer of a wide range of chemical products with manufacturing facilities located in North America, Europe and Australia and operated its business through three segments: Performance Products, Polymers and Base Chemicals. AdMat and its subsidiaries are manufacturers and marketers of advanced epoxy, acrylic and polyurethane-based products used in a wide variety of industrial and consumer applications and operate in a single Advanced Materials segment. We have combined Huntsman LLC's Performance Products and Base Chemicals segments with our Performance Products and Base Chemicals segments and have added Huntsman LLC's Polymers segment and AdMat's Advanced Materials segment, and we now operate our business through six segments: Polyurethanes, Advanced Materials, Performance Products, Pigments, Polymers and Base Chemicals.

        Our principal executive offices are located at 500 Huntsman Way, Salt Lake City, Utah 84108. Our telephone number is (801) 584-5700.

Recent Developments

Potential Spin Off or Sale of Base Chemicals and Polymers Businesses

        On February 24, 2006, Huntsman Corporation announced that it is evaluating strategic options for its business. This evaluation may lead to the sale of certain of our Base Chemicals or Polymers assets or a spin off of these segments and is consistent with the announced potential divestment discussed in "—Pending Sale of U.S. Butadiene and MTBE Business" below. Currently, Huntsman Corporation is in the early stages of this evaluation and there can be no assurance that we will ultimately sell any assets or spin off our Base Chemicals and Polymers segments.

Pending Sale of U.S. Butadiene and MTBE Business

        On February 24, 2006, Huntsman Corporation announced that it signed a letter of intent to sell the assets of our U.S. butadiene and MTBE business operated in our Base Chemicals segment, which includes a manufacturing facility located at Port Neches, Texas, to Texas Petrochemicals, L.P. for a sales price of $275 million, subject to customary adjustments. We expect the transaction to close in mid-2006. The manufacturing facility has a capacity of approximately 900 million pounds of butadiene per year and approximately 11,000 barrels per day of MTBE. The business has approximately 240 employees, 2005 revenues of approximately $626 million and 2005 EBITDA of approximately $43 million.

        Our PO/MTBE facilities at Port Neches, Texas (operated in our Polyurethanes segment) and our oxides/olefins facilities at Port Neches, Texas, along with our facilities in nearby Port Arthur, Texas are not included in the sale.

Pending Acquisition of Textile Effects Business

        On February 20, 2006, Huntsman Corporation announced that it has entered into a definitive agreement to acquire the global Textile Effects ("TE") business of Ciba Specialty Chemicals Inc. for CHF 332 million ($253 million). The purchase price will be reduced (i) by approximately CHF 75 million ($57 million) in assumed debt and unfunded pension and other post employment liabilities and (ii) up to approximately CHF 40 million ($31 million) in unspent restructuring costs. The final

2

purchase price is subject to a working capital and net debt adjustment. The transaction is subject to customary terms and conditions, and is expected to occur by the end of the third quarter of 2006.

        The TE business has headquarters in Basel, Switzerland, and manufactures a broad range of chemical and dye products that enhance the performance properties and color of finished textiles and materials. The TE business serves over 10,000 customers in 80 countries and is the leading global supplier of comprehensive solutions for the textile industry. The TE business has approximately 4,200 employees and operates eleven primary manufacturing facilities located in eight countries. The TE business had approximately CHF 1.3 billion ($1 billion) in revenues and approximately CHF 115 million ($92 million) in EBITDA in 2005. From the date of the acquisition of the TE business through approximately the first half of 2008, we would expect to incur restructuring costs totaling approximately $50 million and to make capital expenditures totaling approximately $100 million associated with the TE business.

Discussions Concerning the Potential Sale of Huntsman Corporation

        On January 31, 2006, Huntsman Corporation, our parent, confirmed that, in late 2005, it received an indication of interest regarding the acquisition of all of its outstanding common shares. In response to this indication of interest, the board of directors of Huntsman Corporation engaged financial and legal advisors to assist it in evaluating the potential sale of Huntsman Corporation and other alternatives to enhance stockholder value, including to continue executing its business plan. The board also formed a special committee with authority to make a recommendation. As part of this process, Huntsman Corporation contacted, obtained proposals from, and held discussions with a limited number of potential acquirers or merger partners. After careful review of the proposals received, other prospects and alternatives available at the time, as well as thorough discussions with the parties, the board of directors of Huntsman Corporation and its special committee concluded that none of the proposals were in the best interests of Huntsman Corporation stockholders.

Impact of 2005 U.S. Gulf Coast Storms

        While the 2005 U.S. Gulf Coast storms did not cause serious structural damage to our facilities, they did cause operational disruptions for us and certain of our suppliers and customers. Some of our products were temporarily negatively impacted by restrictions on the availability of certain raw materials and our business was adversely impacted by logistics and transportation disruptions. Certain of our operations were suspended for much of the fourth quarter of 2005.

        Energy costs, as well as the costs of many of our key feedstocks, spiked to unprecedented levels during the third and fourth quarters of 2005. In response to these increased costs and tight supply conditions, we increased prices for many of our products. Nevertheless, we estimate that these events had a direct negative effect on our EBITDA for the six months ended December 31, 2005 of approximately $167 million, approximately $140 million of which was incurred in the fourth quarter of

3

2005. The following table shows the estimated negative impact on our EBITDA by segment for the six months ended December 31, 2005 (dollars in millions):

Estimated EBITDA* Impact

*

For a discussion of EBITDA and a reconciliation of EBITDA to net income and cash provided by operating activities, see "Management's Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations."

        Related to the continuing effects of the storms, in late January 2006, one of our suppliers suffered two boiler failures that resulted in damages to certain of our facilities in Jefferson County, Texas. This damage caused unplanned outages and repair costs that we estimate will have a negative impact of approximately $15 million on our results of operations in the first quarter of 2006. Other than this incident, we do not expect any significant continuing impacts from the 2005 U.S. Gulf Coast storms in 2006.

        We are in the process of preparing claims for possible recovery of damages under our insurance policies for property damage and business interruption resulting from the 2005 U.S. Gulf Coast storms (including for the 2006 incident discussed above at our Jefferson County, Texas facility). While we can provide no assurances that we will recover these damages (or the amount of recovery, if any), we anticipate obtaining at least a partial recovery, net of insurance deductibles, by the end of 2006.

Proposed Amendments to Accounts Receivable Securitization Program

        As of December 31, 2005, our off-balance sheet accounts receivable securitization program ("A/R Securitization Program") had approximately $192.2 million in U.S. dollar equivalents in medium-term notes outstanding and approximately $110.1 million in U.S. dollar equivalents in commercial paper outstanding. On March 31, 2006, we caused a conditional notice of redemption to be given to the medium-term note holders to redeem in full the outstanding medium-term notes on April 18, 2006. This notice is revocable by us up to three business days prior to the redemption and is conditional upon the completion of the amendment and expansion of our commercial paper program by an amount sufficient to redeem the medium-term notes.

        While we can provide no assurances, we expect to complete the amendment and expansion of our commercial paper program on or before April 18, 2006. We expect to increase the commitment amount of commercial paper from $175 million to $500 million. As noted, the increase will be used to redeem the medium-term notes in full. In addition, the agreements governing our senior secured credit facilities require us to prepay our term loan B borrowings with proceeds raised under the A/R Securitization Program in excess of $425 million, and we anticipate that we will prepay approximately $50 million of our term loan B borrowings. The expansion of the A/R Securitization Program will be supported by the inclusion of eligible accounts receivable primarily pertaining to U.S. operations that were merged with and into our Company in the HLLC Merger.

Our Business

        We are among the world's largest global manufacturers of differentiated and commodity chemical products. We manufacture a broad range of chemical products and formulations, which are marketed in more than 100 countries to a diversified group of consumer and industrial customers. Our products are used in a wide range of applications, including those in the adhesives, aerospace, automotive, construction products, durable and non-durable consumer products, electronics, medical, packaging, paints and coatings, power generation, refining and synthetic fiber industries. We are a leading global producer in many of our key product lines, including MDI, amines, surfactants, epoxy-based polymer formulations, maleic anhydride and titanium dioxide. Our administrative, research and development and manufacturing operations are primarily conducted at the 67 facilities that we own or lease. Our facilities are located in 24 countries and we employ approximately 10,800 associates worldwide. Our businesses benefit from significant integration, large production scale and proprietary manufacturing technologies, which allow us to maintain a low-cost position.

        Our business is organized around our six segments: Polyurethanes, Advanced Materials, Performance Products, Pigments, Polymers and Base Chemicals. These segments can be divided into two broad categories: differentiated and commodity. We produce differentiated products primarily in our Polyurethanes, Advanced Materials and Performance Products segments. These products serve diverse end markets and are generally characterized by historical growth in excess of GDP growth, resulting from product substitution and new product development, proprietary manufacturing processes and product formulations and a high degree of customer loyalty. Demand for these products tends to be driven by the value-added attributes that they create in our customers' end-use applications. While the demand for these differentiated products is also influenced by worldwide economic conditions and GDP growth, our differentiated products have tended to produce more stable profit margins and higher demand growth rates than our commodity products.

        In our commodity chemical businesses, we produce titanium dioxide derived from titanium-bearing ores in our Pigments segment and petrochemical-based olefins, aromatics and polyolefins products in our Polymers and Base Chemicals segments. Since the coatings industry consumes a substantial portion of titanium dioxide production, seasonal demand patterns in the coatings industry drive the profitability of our Pigments segment; profitability is also driven by industry-wide operating rates, with a lag of up to twelve months due to the effects of stocking and destocking by customers and suppliers. The profitability of our Polymers and Base Chemicals segments has historically been cyclical in nature. The industry has recently operated in an up cycle that resulted primarily from strong demand reflecting global economic conditions and the fact that there have been no recent North American or European capacity additions. However, volatile crude oil and natural gas-based raw materials costs and a recent weakening in demand could negatively impact the future profitability of our Polymers and Base Chemicals segments.

The New Notes

        The terms of the new notes and those of the outstanding old notes are identical in all material respects, except:

(1)

the new notes will have been registered under the Securities Act;



(2)

the new notes will not contain transfer restrictions and registration rights that relate to the old notes; and



(3)

the new notes will not contain provisions relating to the payment of liquidated damages to be made to the holders of the old notes under circumstances related to the timing of the exchange offer.

10

        A brief description of the material terms of the new notes follows:

11

12

        For additional information regarding the notes, see "Description of New Notes."

Failure to Exchange Your Old Notes

        The old notes which you do not tender or we do not accept will, following the exchange offer, continue to be restricted securities. Therefore, you may only transfer or resell them in a transaction registered under or exempt from the Securities Act and all applicable state securities laws. We will issue the new notes in exchange for the old notes under the exchange offer only following the satisfaction of the procedures and conditions described under the caption "The Exchange Offer."

13

        Because we anticipate that most holders of the old notes will elect to exchange their old notes, we expect that the liquidity of the markets, if any, for any old notes remaining after the completion of the exchange offer will be substantially limited. Any old notes tendered and exchanged in the exchange offer will reduce the aggregate principal amount outstanding of the old notes.

Other Debt

        As of December 31, 2005, we had $4,123.1 million in debt outstanding other than the old notes.

        The indenture governing the notes limits our ability to incur additional debt. Consequently, we would be required to obtain an amendment of the indenture before we incurred any additional debt, other than the types of debt specifically identified in the indenture as permitted. For more information, see "Other Indebtedness and Certain Financing Arrangements" below.

Summary Historical Financial Data

        On August 16, 2005, we completed the HLLC Merger in which Huntsman LLC, another wholly-owned subsidiary of Huntsman Corporation, merged with and into us and we continued in existence as the surviving entity. At the same time, HIH was also merged into our Company. Prior to the HLLC/HIH Mergers, all of our membership interests were owned by HIH, and HIH was owned 58% by Huntsman Corporation and 42% by Huntsman LLC.

        On December 20, 2005, Huntsman Corporation acquired all of the outstanding interests of AdMat that it did not already own and contributed all of the outstanding equity of AdMat to us in the AdMat Minority Interest Transaction. As a result, AdMat and its subsidiaries have become our subsidiaries. We did not pay any consideration to Huntsman Corporation in connection with the AdMat Minority Interest Transaction other than the issuance of additional equity to Huntsman Corporation.

        Huntsman Corporation effected the HLLC Merger and the AdMat Minority Interest Transaction to simplify its consolidated group's financing and public reporting structure, to reduce its cost of financing and to facilitate other organizational efficiencies. The HLLC/HIH Mergers and the AdMat Minority Interest Transaction were accounted for as an exchange of shares between entities under common control similar to the pooling method. Huntsman LLC and AdMat came under common control with us effective May 1, 2003 and June 30, 2003, respectively. HIH and our Company have been under common control since our inception. The summary historical financial data presented herein reflect the financial position, results of operations and cash flows as if HIH, Huntsman LLC, AdMat and our Company were combined for all periods for which they were under common control.

RISK FACTORS

        You should carefully consider the risks described below in addition to all other information provided to you in this prospectus before participating in this exchange offer. Any of the following risks could materially and adversely affect our business, financial condition, results of operations or cash flows.

We have a history of losses and may incur losses in the future.

        We incurred net losses in four of the last five fiscal years. We will need to continue to generate additional revenues and/or significantly reduce costs, including interest expense, in order to avoid additional net losses in future periods. If we do achieve profitability, we may not sustain or increase profitability on a quarterly or annual basis.

Demand for many of our products is cyclical, and we may experience prolonged depressed market conditions for such products.

        Historically, the markets for many of our products, particularly our commodity products, have experienced alternating periods of tight supply, causing prices and profit margins to increase, followed by periods of capacity additions, resulting in oversupply and declining prices and profit margins. Currently, several of our markets continue to experience conditions of oversupply, and the pricing of our products in these markets is depressed. Future growth in demand for these products may not be sufficient to alleviate any existing or future conditions of excess industry capacity, and such conditions may be sustained or further aggravated by anticipated or unanticipated capacity additions or other events.

        We derive a substantial portion of our revenue from sales of commodity products. Due to the commodity nature of these products, competition in these markets is based primarily on price and to a lesser extent on performance, product quality, product deliverability and customer service. As a result, we may not be able to protect our market position for these products by product differentiation and may not be able to pass on cost increases to our customers. Historically, the prices for our commodity products have been cyclical and sensitive to relative changes in supply and demand, the availability and price of feedstocks and general economic conditions. Our other products may be subject to these same factors, but, typically, the impact of these factors is greatest on our commodity products.

Significant price volatility or interruptions in supply of our raw materials may result in increased costs that we may be unable to pass on to our customers, which could reduce our profitability.

        The prices of the raw materials that we purchase from third parties are cyclical and volatile. We purchase a substantial portion of these raw materials from third party suppliers, and the cost of these raw materials represents a substantial portion of our operating expenses. The prices for a number of these raw materials generally follow price trends of, and vary with market conditions for, crude oil and natural gas feedstocks, which are highly volatile and cyclical. In recent periods we have experienced significantly higher crude oil prices, which have resulted in increased raw material prices.

        Although we frequently enter into supply agreements to acquire these raw materials, these agreements typically provide for market based pricing and provide us only limited protection against price volatility. While we attempt to match cost increases with corresponding product price increases, we are not always able to raise product prices immediately or at all. Timing differences between raw material prices, which may change daily, and contract product prices, which in many cases are negotiated only monthly or less often, have had and may continue to have a negative effect on profitability. If any of our suppliers is unable to meet its obligations under present supply agreements, we may be forced to pay higher prices to obtain the necessary raw materials from other sources and we may not be able to increase prices for our finished products to recoup the higher raw materials cost. In addition, if any of the raw materials that we use become unavailable within the geographic area from

16

which they are now sourced, then we may not be able to obtain suitable and cost effective substitutes. Any underlying cost increase that we are not able to pass on to our customers or any interruption in supply of raw materials could increase our costs or decrease our revenues, which could reduce our profitability.

Natural or other disasters could disrupt our business and result in loss of revenue or in higher expenses.

        Any natural disaster or other serious disruption at any of our facilities due to hurricane, fire, earthquake, flood, terrorist attack or any other natural or man-made disaster could impair our ability to use our facilities and have a material adverse impact on our revenues and increase our costs and expenses. Substantially all of our revenues are derived from products manufactured at facilities, including among others, our U.S. Gulf Coast facilities, which are exposed to the risk of natural disasters. If there is a natural disaster or other serious disruption at any of these facilities, it could impair our ability to adequately supply our customers and negatively impact our operating results. In addition, many of our current and potential customers are concentrated in specific geographic areas. A natural disaster in one of these regions could have a material adverse impact on our U.S. and foreign operations, operating results and financial condition.

Our available cash and access to additional capital may be limited by our substantial leverage, which could restrict our ability to grow our businesses.

        We reduced our indebtedness net of cash, including outstanding borrowings under our off-balance sheet accounts receivable securitization program, during 2005 by approximately $1.6 billion, but we still have a substantial amount of indebtedness outstanding. As of December 31, 2005, we had total consolidated outstanding indebtedness of approximately $4.5 billion (including the current portion of long-term debt). We may incur substantial additional debt from time to time for a variety of purposes. Our outstanding debt could have important consequences for our businesses, including:

•

a high degree of debt will make us more vulnerable to a downturn in our businesses, our industry or the economy in general as a significant percentage of our cash flow from operations will be required to make payments on our indebtedness, making it more difficult to react to changes in our business and in market or industry conditions;



•

a substantial portion of our future cash flow from operations may be required to be dedicated to the payment of principal and interest on indebtedness, thereby reducing the funds available for other purposes, including the growth of our businesses;



•

our ability to obtain additional financing may be constrained due to our existing level of debt; and



•

part of our indebtedness is, and any future debt may be, subject to variable interest rates, which makes us vulnerable to increases in interest rates.

        Our existing debt instruments contain restrictive covenants that may limit our ability to utilize our cash flow to operate our businesses by restricting our ability to, among other things, make prepayments of certain debt, receive dividends from our subsidiaries, make investments and merge or consolidate and transfer or sell assets.

        As of December 31, 2005, the current portion of our long term debt totaled $44.6 million. We estimate that our annual interest expense for 2006 will be approximately $375 million. As of December 31, 2005, we had combined outstanding variable rate borrowings of approximately $2.3 billion. Assuming a 1% increase in interest rates, without giving effect to interest rate hedges, our annual interest rate expense would increase by approximately $23 million.

17

        If we are unable to generate sufficient cash flow or are otherwise unable to obtain the funds required to meet payments of principal and interest on our indebtedness, or if we otherwise fail to comply with the various covenants in the instruments governing our indebtedness, we could be in default under the terms of those instruments. In the event of a default, a holder of the indebtedness could elect to declare all the funds borrowed under those instruments to be due and payable together with accrued and unpaid interest, the lenders under our credit facilities could elect to terminate their commitments thereunder and we or one or more of our subsidiaries could be forced into bankruptcy or liquidation. Any of the foregoing consequences could restrict our ability to grow our business.

A downgrade in the ratings of the securities of our Company or our subsidiaries could result in increased interest and other financial expenses related to future borrowings of our Company or our subsidiaries and could restrict our access to additional capital or trade credit.

        Standard and Poor's Ratings Services and Moody's Investors Service maintain credit ratings for us and our parent, Huntsman Corporation. Each of these ratings is currently below investment grade. Any decision by these or other ratings agencies to downgrade such ratings in the future could result in increased interest and other financial expenses relating to our future borrowings and could restrict our ability to obtain additional financing on satisfactory terms. In addition, any downgrade could restrict our access to, and negatively impact the terms of, trade credit extended by our suppliers of raw materials.

Existing or future litigation or legislative initiatives restricting the use of MTBE in gasoline may subject us or our products to environmental liability, materially reduce our sales and/or materially increase our costs.

        We produce MTBE, an oxygenate that is blended with gasoline to reduce vehicle air emissions and to enhance the octane rating of gasoline. The use of MTBE has become controversial in the U.S. and elsewhere and has been curtailed and may be eliminated in the future by legislation or regulatory action. For example, about 25 states have adopted rules that prohibit or restrict the use of MTBE in gasoline sold in those states. Those states account for a substantial portion of the "pre-ban" U.S. MTBE market. In addition, the Energy Policy Act of 2005 is beginning to have an adverse impact on our MTBE business in the U.S., since it mandates increased use of renewable fuels and eliminates the oxygenate requirement for reformulated gasoline established by the 1990 Clean Air Act Amendments. Although the extent of the potential impact of the new law is still unclear, there have been indications that certain gasoline refiners and distributors may stop using MTBE and that certain pipeline companies may stop shipping gasoline containing MTBE. A significant loss in demand for our MTBE in the U.S. could result in a material loss in revenues or material costs or expenditures. Moreover, additional phase-outs or other future regulation of MTBE may result in a reduction in demand for our MTBE in the U.S.

        In 2005, we marketed approximately 95% of our MTBE to customers located in the U.S. for use as a gasoline additive. Most of our 2005 sales of MTBE to U.S. customers were made pursuant to long-term agreements. During 2006 (and concluding by the first quarter of 2007), our long-term MTBE sales agreements will terminate. We anticipate that our 2006 sales of MTBE in the U.S. will decrease substantially as compared to 2005 levels. Nevertheless, we expect to continue to sell a portion of our MTBE into the U.S. market, although not pursuant to any new long-term agreements. We have entered into sales agreements to sell a significant percentage of our MTBE into the Latin American market, and we currently believe that we could also sell MTBE relatively efficiently in Europe and Asia. Nevertheless, as a result of varying market prices and transportation costs, sales of MTBE in markets outside the U.S. may produce lower margins than the sale of MTBE in the U.S. We may also elect to use all or a portion of our precursor TBA to produce saleable products other than MTBE. If we opt to produce products other than MTBE, necessary modifications to our facilities will require us to make

18

significant capital expenditures and the sale of such other products may produce a lower level of cash flow than the sale of MTBE.

        A number of lawsuits have been filed, primarily against gasoline manufacturers, marketers and distributors, by persons seeking to recover damages allegedly arising from the presence of MTBE in groundwater. While we have not been named as a defendant in any litigation concerning the environmental effects of MTBE, we cannot provide assurances that we will not be involved in any such litigation or that such litigation will not have a material adverse effect on our business, results of operations and financial condition.

Our results of operations may be adversely affected by fluctuations in currency exchange rates and international business risks.

        Some of our subsidiaries conduct a significant portion of their business outside the U.S. These operations outside the U.S. are subject to risks normally associated with international operations. These risks include the need to convert currencies which may be received for our products into currencies in which our subsidiaries purchase raw materials or pay for services, which could result in a gain or loss depending on fluctuations in exchange rates. In addition, we translate our local currency financial results into U.S. dollars based on average exchange rates prevailing during the reporting period or the exchange rate at the end of that period. During times of a strengthening U.S. dollar, our reported international sales and earnings may be reduced because the local currency may translate into fewer U.S. dollars. Because we currently have significant operations located in the United Kingdom and continental Europe, we are primarily exposed to fluctuations in the pound sterling, the euro and the Swiss franc. Furthermore, we anticipate increased exposure to the Chinese renminbi following completion of the construction of our MDI production facilities in China through our Chinese joint ventures, currently expected in 2006.

        Other risks of international operations include trade barriers, tariffs, exchange controls, national and regional labor strikes, social and political risks, general economic risks and required compliance with a variety of foreign laws, including tax laws. Furthermore, in foreign jurisdictions where process of law may vary from country to country, we may experience difficulty in enforcing agreements. In jurisdictions where bankruptcy laws and practices may vary, we may experience difficulty collecting foreign receivables through foreign legal systems. The occurrence of these risks could disrupt the businesses of our international subsidiaries, which could significantly affect their ability to make distributions to us.

The industries in which we compete are highly competitive, and we may not be able to compete effectively with our competitors that have greater financial resources, which could reduce the trading price of our securities.

        The industries in which we operate are highly competitive. Among our competitors are some of the world's largest chemical companies and major integrated petroleum companies that have their own raw material resources. Some of these companies may be able to produce products more economically than we can. In addition, some of our competitors have greater financial resources, which may enable them to invest significant capital into their businesses, including expenditures for research and development. If any of our current or future competitors develops proprietary technology that enables them to produce products at a significantly lower cost, our technology could be rendered uneconomical or obsolete. Moreover, certain of our businesses use technology that is widely available. Accordingly, barriers to entry, apart from capital availability, are low in certain commodity product segments of our business, and the entrance of new competitors into the industry may reduce our ability to capture improving profit margins in circumstances where capacity utilization in the industry is increasing. Further, petroleum-rich countries have become more significant participants in the petrochemical industry and may expand this role significantly in the future. Increased competition in any of our

19

businesses could compel us to reduce the prices of our products, which could result in reduced profit margins and/or loss of market share and reduce the trading price of our securities.

Our operations involve risks that may increase our operating costs, which could reduce our profitability.

        Although we take precautions to enhance the safety of our operations and minimize the risk of disruptions, our operations are subject to hazards inherent in the manufacturing and marketing of differentiated and commodity chemical products. These hazards include chemical spills, pipeline leaks and ruptures, storage tank leaks, discharges or releases of toxic or hazardous substances or gases and other hazards incident to the manufacturing, processing, handling, transportation and storage of dangerous chemicals. We are also potentially subject to other hazards, including natural disasters and severe weather; explosions and fires; transportation problems, including interruptions, spills and leaks; mechanical failures; unscheduled downtimes; labor difficulties; remediation complications; and other risks.

        Many of these hazards can cause bodily injury and loss of life, severe damage to or destruction of property and equipment and environmental damage and may result in suspension of operations and the imposition of civil or criminal penalties and liabilities. Furthermore, we are subject to present and future claims with respect to workplace exposure, exposure of contractors on our premises, as well as other persons located nearby, workers' compensation and other matters.

        We maintain property, business interruption and casualty insurance policies which we believe are in accordance with customary industry practices, but we are not fully insured against all potential hazards and risks incident to our business. We maintain property damage and business interruption insurance policies with aggregate limits of $1.25 billion per occurrence and products liability and sudden and accidental insurance policies with aggregate per occurrence and annual limits of $600 million. We also maintain insurance policies covering other types of risks, including pollution legal liability insurance. Each of these insurance policies is subject to customary exclusions, deductibles and coverage limits. As a result of market conditions, premiums and deductibles for certain insurance policies can increase substantially and, in some instances, certain insurance may become unavailable or available only for reduced amounts of coverage. If we were to incur a significant liability for which we were not fully insured, it could materially increase our operating costs and therefore reduce our profitability.

        In addition, we are subject to various claims and litigation in the ordinary course of business. In conjunction with many of our past acquisitions, we have obtained indemnity agreements from the prior owners addressing liabilities that may arise from operations and events prior to our ownership. We are a party to several pending lawsuits and proceedings. It is possible that a judgment could be rendered against us in these cases or others in which we could be uninsured or not covered by indemnity and beyond the amounts that we currently have reserved or anticipate incurring for such matters. See "Business—Environmental, Health and Safety Matters" and "Legal Matters."

We are subject to many environmental and safety regulations that may result in unanticipated costs or liabilities, which could reduce our profitability.

        We are subject to extensive federal, state, local and foreign laws, regulations, rules and ordinances relating to pollution, protection of the environment and the generation, storage, handling, transportation, treatment, disposal and remediation of hazardous substances and waste materials. Actual or alleged violations of environmental laws or permit requirements could result in restrictions or prohibitions on plant operations, substantial civil or criminal sanctions, as well as, under some environmental laws, the assessment of strict liability and/or joint and several liability. Moreover, changes in environmental regulations could inhibit or interrupt our operations, or require us to modify our facilities or operations. Accordingly, environmental or regulatory matters may cause us to incur

20

significant unanticipated losses, costs or liabilities, which could reduce our profitability. See "Business—Environmental, Health and Safety Matters" and "Legal Matters."

        In addition, we could incur significant expenditures in order to comply with existing or future environmental or safety laws. Capital expenditures and costs relating to environmental or safety matters will be subject to evolving regulatory requirements and will depend on the timing of the promulgation and enforcement of specific standards which impose requirements on our operations. Capital expenditures and costs beyond those currently anticipated may therefore be required under existing or future environmental or safety laws.

        Furthermore, we may be liable for the costs of investigating and cleaning up environmental contamination on or from our properties or at off-site locations where we disposed of or arranged for the disposal or treatment of hazardous materials or from disposal activities that pre-dated our purchase of our businesses. We may therefore incur additional costs and expenditures beyond those currently anticipated to address all such known and unknown situations under existing and future environmental laws. See "Business—Environmental, Health and Safety Matters" and "Legal Matters."

We can provide no assurance that our internal control over our financial reporting will be effective when Section 404 of the Sarbanes-Oxley Act of 2002 becomes applicable to us.

        Under Section 404 of the Sarbanes-Oxley Act of 2002 and the rules issued thereunder, our management is required to conduct an evaluation of the effectiveness of our internal control over financial reporting as of each year-end, beginning December 31, 2006. From that point, we will be required to include in our annual report on Form 10-K a report on our management's assessment of the effectiveness of our internal control over financial reporting. Our independent registered public accounting firm will also issue an audit report on management's assessment and on our internal control over financial reporting.

        We have undertaken significant efforts in preparation for the requirements of Section 404. However, given the complexities and inherent risks associated with the operation of internal control over financial reporting, we can provide no assurance that our internal control over financial reporting will be effective when Section 404 becomes applicable to us. Moreover, we can provide no assurance as to any matters that might be reported in our management's assessment of our internal control over financial reporting or our independent registered public accounting firm's audit report. Ineffective internal control over financial reporting could cause investors to lose confidence in our reported financial information and could result in a lower trading price for our securities.

Our business is dependent on our intellectual property. If our patents are declared invalid or our trade secrets become known to our competitors, our ability to compete may be impaired.

        Proprietary protection of our processes, apparatuses and other technology is important to our business. Consequently, we may have to rely on judicial enforcement of our patents and other proprietary rights. While a presumption of validity exists with respect to patents issued to us in the U.S., there can be no assurance that any of our patents will not be challenged, invalidated, circumvented or rendered unenforceable. Furthermore, if any pending patent application filed by us does not result in an issued patent, or if patents are issued to us, but such patents do not provide meaningful protection of our intellectual property, then our ability to compete may be adversely affected. Additionally, our competitors or other third parties may obtain patents that restrict or preclude our ability to lawfully produce or sell our products in a competitive manner, which could result in significantly lower revenues, reduced profit margins and/or loss of market share.

        We also rely upon unpatented proprietary know-how and continuing technological innovation and other trade secrets to develop and maintain our competitive position. While it is our policy to enter into confidentiality agreements with our employees and third parties to protect our intellectual

21

property, these confidentiality agreements may be breached, may not provide meaningful protection for our trade secrets or proprietary know-how, or adequate remedies may not be available in the event of an unauthorized use or disclosure of our trade secrets and know-how. In addition, others could obtain knowledge of our trade secrets through independent development or other access by legal means. The failure of our patents or confidentiality agreements to protect our processes, apparatuses, technology, trade secrets or proprietary know-how could result in significantly lower revenues, reduced profit margins and/or loss of market share.

Loss of key members of our management could disrupt our business.

        We depend on the continued employment and performance of our senior executives and other key members of management. If any of these individuals resigns or becomes unable to continue in his present role and is not adequately replaced, our business operations and our ability to implement our growth strategies could be materially disrupted. We generally do not have employment agreements with, and we do not maintain any "key man" life insurance for, any of our executive officers.

Terrorist attacks, such as the attacks that occurred on September 11, 2001, the continuing military action in Iraq, general instability in various OPEC member nations, the threat of other attacks or acts of war in the U.S. and abroad and increased security regulations related to our industry could adversely affect our business.

        The attacks of September 11, 2001, and subsequent events, including the continuing military action in Iraq, have caused instability in the U.S. and other financial markets and have led, and may continue to lead, to further armed hostilities, prolonged military action in Iraq, or further acts of terrorism in the U.S. or abroad, which could cause further instability in financial markets. Current regional tensions and conflicts in various OPEC member nations, including the continuing military action in Iraq, have caused, and may cause further, increases in raw material costs, particularly natural gas and crude oil based feedstocks, which are used in our operations. The uncertainty surrounding the continuing military action in Iraq and the threat of further armed hostilities or acts of terrorism may impact any or all of our physical facilities and operations, which are located in North America, Europe, Australia, Asia, Africa, South America and the Middle East, or those of our customers. Furthermore, terrorist attacks, subsequent events and future developments in any of these areas may result in reduced demand from our customers for our products. In addition, local, state and federal governments have begun a regulatory process that could lead to new regulations impacting the security of chemical plant locations and the transportation of hazardous chemicals, which could result in higher operating costs. These developments will subject our worldwide operations to increased risks and, depending on their magnitude, could result in significant unanticipated costs, lower revenues and/or reduced profit margins.

Future acquisitions, partnerships and joint ventures may require significant resources and/or result in significant unanticipated losses, costs or liabilities.

        In the future we may seek to grow our Company and businesses by making acquisitions or entering into partnerships and joint ventures. Any future acquisition, partnership or joint venture may require that we make a significant cash investment, issue stock or incur substantial debt. In addition, acquisitions, partnerships or investments may require significant managerial attention, which may be diverted from our other operations. These capital, equity and managerial commitments may impair the operation of our businesses. Furthermore, any future acquisitions of businesses or facilities could entail a number of additional risks, including:

•

problems with effective integration of operations;



•

the inability to maintain key pre-acquisition business relationships;



•

increased operating costs;

22

•

exposure to unanticipated liabilities; and



•

difficulties in realizing projected efficiencies, synergies and cost savings.

        We have incurred indebtedness to finance past acquisitions. We may finance future acquisitions with additional indebtedness and/or by issuing additional equity securities. As a result, we could face the financial risks associated with incurring additional indebtedness such as reducing our liquidity and access to financing markets and increasing the amount of cash flow required to service such indebtedness.

Risks Related to the Notes

Despite our current levels of indebtedness, we may incur substantially more debt, which could further increase the risks associated with our substantial indebtedness.

        Although the agreements governing our outstanding indebtedness contain, and the indenture governing the notes contains, restrictions on the incurrence of additional indebtedness by us and our restricted subsidiaries, these restrictions are subject to a number of qualifications and exceptions, and the indebtedness incurred in compliance with these restrictions could be substantial. As of December 31, 2005, we had approximately $617.5 million available for additional revolving borrowings, or, within limits, issuances of letters of credit under our senior secured credit facilities. In addition to amounts that may be borrowed under our senior secured credit facilities, the indenture governing the notes also will allow us and our restricted subsidiaries to borrow significant amounts of money from other sources and will place no restrictions on borrowings by our unrestricted subsidiaries. Also, these restrictions do not prevent us from incurring obligations that do not constitute "indebtedness" as defined in the relevant agreement. If new debt is added to the current debt levels, the related risks that we now face could intensify.

We and the guarantors of the notes are permitted to provide guarantees of indebtedness of our parent. The indenture does not contain restrictions on such parent company and in certain circumstances the guarantees that we and the guarantors are permitted to issue in respect of such parent company's debt may be senior in right of payment to the notes or the guarantees of the notes, as the case may be.

        The indenture provides that we and the guarantors of the notes may provide guarantees of indebtedness of our parent if, among other things, the proceeds of such parent's indebtedness are used to refinance our indebtedness. The amount of such guarantees by us and the guarantors shall be limited to the amount of our indebtedness that is so refinanced plus the amount of premiums and expenses to be paid, in each case in connection with such refinancing of our debt. The parent company whose indebtedness we and the guarantors so guarantee will not be governed by the covenants in the indenture governing the notes relating to, among other things, restricted payments and incurrence of indebtedness. There is a significant risk that such parent company's indebtedness, including our and our subsidiaries' guarantees of such parent indebtedness, may be satisfied from the assets of our Company and the guarantors. If our or our subsidiaries' guarantees of parent indebtedness rank senior in right of payment to the notes and the guarantees and our parent becomes insolvent, our parent's creditors may assert claims against us or our subsidiaries that are senior in right of payment to claims of holders of the notes. See "Description of New Notes—Description of the Notes and the Guarantees—Certain Covenants—Limitation on Incurrence of Additional Indebtedness," "—Limitation on Restricted Payments," "—Limitation on Liens" and "—Limitations on Transactions with Affiliates."

23

The instruments governing our debt contain cross default provisions that may cause all of the debt issued under such instruments to become immediately due and payable as a result of a default under an unrelated debt instrument.

        The indentures governing our outstanding senior notes and senior subordinated notes and the notes contain numerous covenants, and the agreements governing our senior secured credit facilities contain numerous covenants and require us to meet certain financial ratios and tests. Our failure to comply with the obligations contained in the indentures governing our outstanding senior notes and senior subordinated notes and the notes, our senior secured credit facilities or other instruments governing our indebtedness could result in an event of default under the applicable instrument, which could result in the related debt and the debt issued under other instruments becoming immediately due and payable. In such an event, the liquidity provided by our securitization program could also be lost. Under such circumstances, we would need to raise funds from alternative sources, which funds may not be available to us on favorable terms, on a timely basis or at all. Alternatively, such a default could require us to sell our assets and otherwise curtail operations in order to pay our creditors.

The notes and the subsidiary guarantees are subordinated to our and the subsidiary guarantors' senior debt.

        The notes are our senior subordinated obligations. Accordingly, the notes are subordinated to all of our existing and future senior debt. We expect to incur additional senior debt from time to time in the future. The indenture governing the notes limits, but does not prohibit, the incurrence of other debt by us, including senior debt. As a result of such subordination, upon any distribution to our creditors in a liquidation, dissolution, bankruptcy, reorganization or any similar proceeding by or relating to us or our property, the holders of our senior debt would be entitled to receive payment in full before the holders of the notes would be entitled to receive any payment. In addition, all payments on the notes could be blocked in the event of a default on our senior debt. See "Description of New Notes—Description of the Notes and the Guarantees—Subordination."

        The notes are not secured. The borrowings under our senior secured credit facilities are secured by liens on our assets. If we or any of our subsidiary guarantors liquidates, dissolves or declares bankruptcy, or if payment under the credit agreement or any of our other secured debt is accelerated, our secured lenders would be entitled to exercise the remedies available to a secured lender under applicable law and will have a claim on those assets before the holders of the notes. The guarantees are unsecured senior subordinated obligations of the guarantors, subordinated to all senior indebtedness of the guarantors, and in the event of the bankruptcy or insolvency of a guarantor, such guarantor's secured lenders will have a prior secured claim to any collateral securing the debt owed to them. As of December 31, 2005, we and the subsidiary guarantors had approximately $3,187.0 million of senior debt outstanding to which the notes and the subsidiary guarantees are subordinated, and approximately $617.5 million of additional debt is available for borrowing under our senior secured revolving credit facilities.

The notes are structurally subordinated to all indebtedness of our subsidiaries that are not guarantors of the notes.

        We derive substantially all of our revenue from our consolidated subsidiaries. While certain of our subsidiaries will guarantee the notes, other subsidiaries are not guaranteeing the notes. You will not have any claim as a creditor against our other subsidiaries that are not guarantors of the notes. Accordingly, all obligations of our non-guarantor subsidiaries will have to be satisfied before any of the assets of such subsidiaries would be available for distribution, upon a liquidation or otherwise, to us or a guarantor of the notes. As of December 31, 2005, our non-guarantor subsidiaries had approximately $125.7 million of total indebtedness, excluding intercompany indebtedness.

24

We may not have the ability to repurchase notes upon a change of control as required by the indenture.

        Upon the occurrence of certain change of control events, each holder of notes may require us to repurchase all or a portion of its notes at a purchase price equal to 101% of their principal amount plus accrued interest to the date of purchase. Our ability to repurchase the notes upon a change of control is prohibited by our senior secured credit facilities. In any event, we cannot assure you that we will have sufficient funds to repurchase the notes upon a change of control. Our failure to repurchase the notes upon a change of control would result in a default under the indenture governing the notes, which would, in turn, result in a default under our senior secured credit facilities and our outstanding senior notes and senior subordinated notes.

The notes and guarantees may be void, avoided or subordinated under laws governing fraudulent transfers and insolvency.

        We have incurred substantial debt, including our outstanding senior notes and senior subordinated notes and our senior secured credit facilities. Various fraudulent conveyance laws enacted for the protection of creditors may apply to our issuance of the notes and the guarantors' issuance of the guarantees. To the extent that a court were to find that:

(1)

the notes were issued or a guarantee was incurred with actual intent to hinder, delay or defraud any present or future creditor; or



(2)

we or a guarantor did not receive fair consideration or reasonably equivalent value for issuing the notes or guarantees; and that we or a guarantor



(A)

was insolvent;



(B)

was rendered insolvent by reason of the issuance of the notes or a guarantee;



(C)

was engaged or about to engage in a business or transaction for which our or its remaining assets or those of a guarantor constituted unreasonably small capital; or



(D)

intended to incur, or believed that we or it would incur, debts beyond our or its ability to pay those debts as they matured;

then the court could void the notes and the guarantees or subordinate the notes or the guarantees in favor of our or the guarantor's other creditors. Furthermore, to the extent that the notes or a guarantee were voided as a fraudulent conveyance or held unenforceable for any other reason:

•

claims of holders of the notes against us or a guarantor would be adversely affected;



•

the notes or the guarantees would be effectively subordinated to all obligations of our other creditors or the creditors of the guarantor; and



•

the other creditors would be entitled to be paid in full before any payment could be made on the notes or the guarantees.

There is no established trading market for the new notes, and any market for the new notes may be illiquid.

        The new notes are a new issue of securities with no established trading market. We cannot assure you that a liquid market will develop for the new notes, that you will be able to sell your new notes at a particular time or that the prices that you will receive when you sell will be favorable. We do not intend to apply for listing of the new notes on any U.S. securities exchange or for quotation through an automated dealer quotation system. We intend to list the euro notes on the official list of the Luxembourg Stock Exchange and for trading on the Euro MTF Market of the Luxembourg Stock Exchange. The liquidity of the trading market in the new notes and the market price quoted for the new notes may be adversely affected by changes in the overall market for high yield securities generally

25

or the interest of securities dealers in making a market in the new notes and by changes in our financial performance or prospects or in the prospects for companies in the chemical industry generally. As a result, you cannot be sure that an active trading market will develop for the new notes. This offer to exchange the new notes for the old notes does not depend upon any minimum amount of old notes being tendered for exchange.

        Unless you are an affiliate of our Company within the meaning of Rule 405 under the Securities Act, you may offer for resale, resell or otherwise transfer new notes without compliance with the registration and prospectus delivery provisions of the Securities Act, so long as you acquired the new notes in the ordinary course of business and have no arrangement or understanding with respect to the distribution of the new notes to be acquired in the exchange offer. If you tender your old notes for the purpose of participating in a distribution of the new notes, you must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction.

If you do not exchange your old notes, they may be difficult to resell.

        It may be difficult for you to sell old notes that are not exchanged in this exchange offer, since any old notes not exchanged will remain subject to the restrictions on transfer provided for in Rule 144 under the Securities Act. These restrictions on transfer of your old notes exist because we issued the old notes pursuant to an exemption from the registration requirements of the Securities Act and applicable state securities laws. Generally, the old notes that are not exchanged for new notes in this exchange offer will remain restricted securities and, unless registered under the Securities Act, may not be offered or sold except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. Other than in this exchange offer, we do not intend to register the old notes under the Securities Act.

        To the extent any old notes are tendered and accepted in this exchange offer, the trading market, if any, for the old notes that remain outstanding after this exchange offer would be adversely affected due to a reduction in market liquidity.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

        Certain information set forth in this prospectus contains "forward-looking statements" within the meaning of the federal securities laws. Forward-looking statements include statements concerning our plans, objectives, goals, strategies, future events, future revenues or performance, capital expenditures, financing needs, plans or intentions relating to acquisitions and other information that is not historical information. In some cases, forward-looking statements can be identified by terminology such as "believes," "expects," "may," "will," "should," "anticipates," or "intends" or the negative of such terms or other comparable terminology, or by discussions of strategy. We may also make additional forward-looking statements from time to time. All such subsequent forward-looking statements, whether written or oral, by us or on our behalf, are also expressly qualified by these cautionary statements.

        All forward-looking statements, including without limitation, management's examination of historical operating trends, are based upon our current expectations and various assumptions. Our expectations, beliefs and projections are expressed in good faith and we believe there is a reasonable basis for them, but, there can be no assurance that management's expectations, beliefs and projections will result or be achieved. All forward-looking statements apply only as of the date made. We undertake no obligation to publicly update or revise forward-looking statements which may be made to reflect events or circumstances after the date made or to reflect the occurrence of unanticipated events.

        There are a number of risks and uncertainties that could cause our actual results to differ materially from the forward-looking statements contained in or contemplated by this prospectus. Any forward-looking statements should be considered in light of the risks set forth under the heading "Risk Factors," and elsewhere in this prospectus.

26

        This prospectus includes information with respect to market share, industry conditions and forecasts that we obtained from internal industry research, publicly available information (including industry publications and surveys), and surveys and market research provided by consultants. The publicly available information and the reports, forecasts and other research provided by consultants generally state that the information contained therein has been obtained from sources believed to be reliable, but there can be no assurance as to the accuracy and completeness of such information. We have not independently verified any of the data from third-party sources, nor have we ascertained the underlying economic assumptions relied upon therein. Similarly, our internal research and forecasts are based upon our management's understanding of industry conditions, and such information has not been verified by any independent sources.

THE EXCHANGE OFFER

Purpose of the Exchange Offer

        When we sold the old notes on December 17, 2004, we entered into an exchange and registration rights agreement with the initial purchasers of those notes. Under the exchange and registration rights agreement, we agreed to file the registration statement of which this prospectus forms a part regarding the exchange of the old notes for notes which are registered under the Securities Act. We also agreed to use our reasonable best efforts to cause the registration statement to become effective with the SEC, and to conduct this exchange offer after the registration statement was declared effective. We will use our best efforts to keep the registration statement effective until the exchange offer is completed. The exchange and registration rights agreement provides that we will be required to pay liquidated damages to the holders of the old notes if the exchange offer has not been completed within 45 days after the effective date of the registration statement. A copy of the exchange and registration rights agreement is filed as an exhibit to the registration statement.

Terms of the Exchange Offer

        This prospectus and the accompanying letters of transmittal together constitute the exchange offer. Upon the terms and subject to the conditions set forth in this prospectus and in the letters of transmittal, we will accept for exchange old notes that are properly tendered on or before the expiration date and are not withdrawn as permitted below. The expiration date for this exchange offer is 5:00 p.m., New York City time, on                        , or such later date and time to which we, in our sole discretion, extend the exchange offer. The exchange offer, however, will be in effect no longer than 45 days from the date of this prospectus.

        The form and terms of the new notes being issued in the exchange offer are the same as the form and terms of the old notes, except that:

•

the new notes will have been registered under the Securities Act;



•

the new notes will not contain transfer restrictions and registration rights that relate to the old notes; and



•

the new notes will not contain provisions relating to the payment of liquidated damages to be made to the holders of the old notes under circumstances related to the timing of the exchange offer.

        Old dollar notes tendered in the exchange offer must be in denominations of the principal amount of $1,000 or any integral multiple thereof. Old euro notes tendered in the exchange offer must be in denominations of the principal amount of €1,000 or any integral multiple thereof.

        We expressly reserve the right, in our sole discretion:

•

to extend the expiration date;

27

•

to delay accepting any old notes;



•

if any of the conditions set forth below under "—Conditions to the Exchange Offer" have not been satisfied, to terminate the exchange offer and not accept any notes for exchange; and



•

to amend the exchange offer in any manner.

        We will give oral or written notice of any extension, delay, non-acceptance, termination or amendment as promptly as practicable by a public announcement, and in the case of an extension, no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration date.

        During an extension, all old notes previously tendered will remain subject to the exchange offer and may be accepted for exchange by us. Any old notes not accepted for exchange for any reason will be returned without cost to the holder that tendered them promptly after the expiration or termination of the exchange offer.

How to Tender Old Notes for Exchange

        We have forwarded to you, along with this prospectus, letters of transmittal relating to this exchange offer. Because all of the old notes are held in book-entry accounts maintained by the relevant exchange agent at DTC, Euroclear or Clearstream, Luxembourg, a holder need not submit a letter of transmittal if the holder tenders old notes in accordance with the procedures mandated by DTC's Automated Tender Offer Program ("ATOP") or by Euroclear or Clearstream, Luxembourg, as the case may be. To tender old notes without submitting a letter of transmittal, the electronic instructions sent to DTC, Euroclear or Clearstream, Luxembourg and transmitted to the relevant exchange agent must contain your acknowledgment of receipt of, and your agreement to be bound by and to make all of the representations contained in, the letter of transmittal. In all other cases, a letter of transmittal must be manually executed and delivered as described in this prospectus.

        We have appointed two separate exchange agents in connection with this exchange offer. Wells Fargo Bank, N.A (the "dollar exchange agent") has been appointed as the exchange agent with responsibility for the tender and exchange of all old dollar notes for new dollar notes. Citibank, N.A. (the "euro exchange agent" and, together with the dollar exchange agent, the "exchange agents") has been appointed as the exchange agent with responsibility for the tender and exchange of all old euro notes for new euro notes. Holders of old notes are responsible for knowing which exchange agent is responsible for the type of notes such holder wishes to tender. Any letters of transmittal or other instructions sent by a holder to the wrong exchange agent may be delayed or rejected.

        Only a holder of record of old notes may tender old notes in the exchange offer. To tender in the exchange offer, a holder must comply with the procedures of DTC or Euroclear or Clearstream, Luxembourg, as applicable, and either:

•

complete, sign and date the letter of transmittal, or a facsimile of the letter of transmittal; have the signature on the letter of transmittal guaranteed if the letter of transmittal so requires; and deliver the letter of transmittal or facsimile to the relevant exchange agent prior to the expiration date; or



•

in lieu of delivering a letter of transmittal, comply with the instructions and procedures of DTC or Euroclear or Clearstream, Luxembourg, as the case may be, for the transmittal on behalf of the holder of a computer-generated message to the relevant exchange agent in which the holder of the old notes acknowledges and agrees to be bound by the terms of the letter of transmittal, which computer-generated message shall be received by the relevant exchange agent prior to 5:00 p.m., New York City time, on the expiration date.

28

        In addition, either:

•

the relevant exchange agent must receive old notes along with the letter of transmittal; or



•

with respect to the old dollar notes, the dollar exchange agent must receive, before expiration of the exchange offer, timely confirmation of book-entry transfer of old dollar notes into the dollar exchange agent's account at DTC, according to the procedure for book-entry transfer described below; or



•

with respect to the old euro notes, the euro exchange agent must receive, before the expiration date, timely confirmation from Euroclear or Clearstream, Luxembourg that the securities account to which the old euro notes are credited has been blocked from and including the day on which the confirmation is delivered to the euro exchange agent and that no transfers will be effected in relation to such old euro notes at any time after such date.

        To be tendered effectively, the appropriate exchange agent must receive any physical delivery of the letter of transmittal and other required documents at such exchange agent's address set forth below under the caption "—The Exchange Agents" before expiration of the exchange offer. To receive confirmation of valid tender of old notes, a holder should contact the relevant exchange agent at the corresponding telephone number listed under the caption "—The Exchange Agents".

        The tender by a holder that is not withdrawn before expiration of the exchange offer will constitute an agreement between that holder and us in accordance with the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal. Only a registered holder of old notes may tender the old notes in the exchange offer. If a holder completing a letter of transmittal tenders less than all of the old notes held by such holder, such tendering holder should fill in the applicable box of the letter of transmittal. The amount of old notes delivered to the exchange agent will be deemed to have been tendered, unless otherwise indicated.

        If old notes, the letter of transmittal or any other required documents are physically delivered to an exchange agent, the method of delivery is at the holder's election and risk. Rather than mail these items, we recommend that holders use an overnight or hand delivery service. In all cases, holders should allow sufficient time to assure delivery to such exchange agent before expiration of the exchange offer. Holders should not send the letter of transmittal or old notes to us. Holders may request their respective brokers, dealers, commercial banks, trust companies or other nominees to effect the above transactions for them.

        Any beneficial owner whose old notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and who wishes to tender should contact the registered holder promptly and instruct it to tender on the owner's behalf. If the beneficial owner wishes to tender on its own behalf, it must, prior to completing and executing the letter of transmittal and delivering its old notes, either:

•

make appropriate arrangements to register ownership of the old notes in the owner's name; or



•

obtain a properly completed bond power from the registered holder of old notes.

        The transfer of registered ownership may take considerable time and may not be completed prior to the expiration date.

        If the applicable letter of transmittal is signed by the record holder(s) of the old notes tendered, the signature must correspond with the name(s) written on the face of the old note without alteration, enlargement or any change whatsoever. If the applicable letter of transmittal is signed by a participant in DTC or Euroclear or Clearstream, Luxembourg, as applicable, the signature must correspond with the name as it appears on the security position listing as the holder of the old notes.

29

        Signatures on a letter of transmittal or a notice of withdrawal, as the case may be, must be guaranteed, unless the old notes surrendered for exchange are tendered:

(1)

by a holder of old notes who has not completed the box entitled "Special Issuance Instructions" or "Special Delivery Instructions" on the letter of transmittal; or



(2)

for the account of an "eligible institution."

        An "eligible institution" is a financial institution, including most banks, savings and loan associations and brokerage houses, that is a participant in the Securities Transfer Agents Medallion Program, the New York Stock Exchange Medallion Signature Program or the Stock Exchanges Medallion Program.

        If signatures on a letter of transmittal or notice of withdrawal are required to be guaranteed, the guarantor must be an eligible institution. If old notes are registered in the name of a person other than the signer of the letter of transmittal, the old notes surrendered for exchange must be endorsed by, or accompanied by a written instrument or instruments of transfer or exchange, in satisfactory form as determined by us in our sole discretion, duly executed by the registered holder with the holder's signature guaranteed by an eligible institution.

        If a person or persons other than the registered holder or holders of the old notes tendered for exchange signs the letter of transmittal, the tendered notes must be endorsed or accompanied by appropriate powers of attorney, in either case signed exactly as the name or names of the registered holder or holders that appear on the old notes.

        If trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity sign the letter of transmittal or any old notes or any power of attorney, such persons should so indicate when signing, and you must submit proper evidence satisfactory to us of such person's authority to so act, unless we waive this requirement.

        We will determine all questions as to the validity, form, eligibility (including time of receipt) and acceptance of old notes tendered for exchange in our sole discretion. Our determination will be final and binding. We reserve the absolute right to:

(1)

reject any and all tenders of any old note improperly tendered;



(2)

refuse to accept any old note if, in our judgment or the judgment of our counsel, acceptance of the old note may be deemed unlawful; and



(3)

waive any defects or irregularities or conditions of tender as to any particular old note either before or after the expiration date, including the right to waive the ineligibility of any holder who seeks to tender old notes in the exchange offer.

        Our interpretation of the terms and conditions of tender as to any particular old note either before or after the expiration date, including the letter of transmittal and the instructions to it, will be final and binding on all parties. Holders must cure any defects and irregularities in connection with tenders of old notes for exchange within such reasonable period of time as we will determine, unless we waive such defects or irregularities. Neither we, the exchange agents nor any other person shall be under any duty to give notification of any defect or irregularity with respect to any tender of old notes for exchange, nor shall any of us incur any liability for failure to give such notification.

        By tendering, each holder will represent to us, among other things, that the person acquiring new notes in this exchange offer is obtaining them in the ordinary course of its business, whether or not such person is the holder, and that neither the holder nor such other person has any arrangement or understanding with any person to participate in the distribution of the new notes issued in this exchange offer. If any holder or any such other person is an "affiliate," as defined under Rule 405 of the Securities Act, of our company, or is engaged in or intends to engage in or has an arrangement or

30

understanding with any person to participate in a distribution of such new notes to be acquired in this exchange offer, such holder or any such other person:

(1)

may not rely on the applicable interpretations of the staff of the SEC; and



(2)

must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction.

        Each broker-dealer who acquired its old notes as a result of market-making activities or other trading activities and thereafter receives new notes issued for its own account in this exchange offer, must acknowledge that it will deliver a prospectus in connection with any resale of such new notes issued in this exchange offer. The letters of transmittal state that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. See "Plan of Distribution" for a discussion of the exchange and resale obligations of broker-dealers in connection with this exchange offer.

Acceptance of Old Notes for Exchange; Delivery of New Notes

        Upon satisfaction or waiver of all of the conditions to this exchange offer, we will accept, promptly after the expiration date, all old notes properly tendered and will issue the new notes registered under the Securities Act. For purposes of this exchange offer, we shall be deemed to have accepted properly tendered old notes for exchange when, as and if we have given oral or written notice to the exchange agent, with written confirmation of any oral notice to be given promptly thereafter. See "—Conditions to the Exchange Offer" for a discussion of the conditions that must be satisfied before we accept any old notes for exchange.

        For each old note accepted for exchange, the holder will receive a new note registered under the Securities Act having a principal amount equal to, and in the denomination of, that of the surrendered old note. Accordingly, registered holders of new notes on the relevant record date for the first interest payment date following the consummation of this exchange offer will receive interest accruing from the most recent date to which interest has been paid or, if no interest has been paid on the old notes, from December 17, 2004. Old notes that we accept for exchange will cease to accrue interest from and after the date of consummation of this exchange offer. Under the exchange and registration rights agreement, we may be required to make additional payments in the form of liquidated damages to the holders of the old notes under circumstances relating to the timing of this exchange offer. We are currently paying additional interest.

        In all cases, we will issue new dollar notes in this exchange offer for old dollar notes that are accepted for exchange only after the dollar exchange agent timely receives:

(1)

certificates for such old dollar notes or a timely book-entry confirmation of such old dollar notes into the dollar exchange agent's account at the book entry transfer facility;



(2)

a properly completed and duly executed letter of transmittal or facsimile thereof, with any required signature guarantees, or an agent's message; and



(3)

all other required documents.

        In all cases, we will issue new euro notes in this exchange offer for old euro notes that are accepted for exchange only after the euro exchange agent timely receives:

(1)

a timely confirmation from Euroclear or Clearstream, Luxembourg that the securities account to which the old euro notes are credited has been blocked;



(2)

a properly completed and duly executed letter of transmittal or facsimile thereof, with any required signature guarantees, or an agent's message; and

31

(3)

all other required documents.

        If for any reason set forth in the terms and conditions of this exchange offer we do not accept any tendered old notes, or if a holder submits old notes for a greater principal amount than the holder desires to exchange, we will return such unaccepted or non-exchanged notes without cost to the tendering holder. In the case of old dollar notes tendered by book-entry transfer into the dollar exchange agent's account at DTC, such non-exchanged old dollar notes will be credited to an account maintained with DTC promptly after the expiration or termination of this exchange offer. In the case of old euro notes tendered in accordance with the blocking procedures of Euroclear or Clearstream, Luxembourg, the old euro notes will be returned to their holder by cancellation of the blocking instruction in accordance with the standard operating procedures of Euroclear or Clearstream, Luxembourg promptly after the expiration or termination of this exchange offer.

DTC Book Entry Transfers

        The dollar exchange agent will make a request to establish an account at DTC with respect to old dollar notes for purposes of this exchange offer promptly upon receipt of this prospectus. Any financial institution that is a participant in DTC's systems must make book-entry delivery of old dollar notes by causing DTC to transfer those old dollar notes into the dollar exchange agent's account at DTC in accordance with DTC's electronic Automated Tender Offer Program procedures for such transfer. Such participant should transmit its acceptance to DTC on or prior to the expiration date or comply with the guaranteed delivery procedures described below. DTC will verify such acceptance, execute a book-entry transfer of the tendered old dollar notes into the dollar exchange agent's account at DTC and then send to the dollar exchange agent confirmation of such book-entry transfer. The confirmation of such book-entry transfer will include an agent's message confirming that DTC has received an express acknowledgment from such participant that such participant has received and agrees to be bound by the letter of transmittal and that we may enforce the letter of transmittal against such participant. Delivery of new dollar notes may be effected through book-entry transfer at DTC, as applicable. However, the letter of transmittal or facsimile thereof, with any required signature guarantees, or an agent's message, and any other required documents, must be transmitted to and received by the dollar exchange agent at the address set forth below under "—The Exchange Agents" on or prior to the expiration date or comply with the guaranteed delivery procedures described below.

Euroclear and Clearstream, Luxembourg Procedures for Blocking Instructions

        The registered holder of the old euro notes on the records of Euroclear or Clearstream, Luxembourg must, unless otherwise instructed by Euroclear or Clearstream, Luxembourg, instruct Euroclear or Clearstream, Luxembourg to block the securities in the account in Euroclear or Clearstream, Luxembourg to which such old euro notes are credited. In order for the exchange offer to be accepted, the euro exchange agent must have received, prior to the expiration date, a confirmation from Euroclear or Clearstream, Luxembourg that the securities account of old euro notes tendered has been blocked from and including the day on which the confirmation is delivered to the euro exchange agent and that no transfers will be effected in relation to the old euro notes at any time after such date. Old euro notes should be blocked in accordance with the procedures of Euroclear or Clearstream, Luxembourg, as the case may be. The exchange of the old euro notes so tendered will only be made after a timely receipt by the euro exchange agent of an agent's message and any other documents required by the letter of transmittal. The term "agent's message" means a message, transmitted by Euroclear or Clearstream, Luxembourg and received by the euro exchange agent which states that Euroclear or Clearstream, Luxembourg has received an express acknowledgment from a participant tendering old euro notes that the participant has received and agrees to be bound by the terms of the letter of transmittal, and that we may enforce that agreement against the participant.

32

        These instructions are subject to the rules and procedures of Euroclear and Clearstream, Luxembourg, which are subject to change. Holders of old euro notes must comply with any and all instructions received from Euroclear and Clearstream, Luxembourg.

Guaranteed Delivery Procedures

        If a registered holder of old dollar notes desires to tender the old dollar notes and the old dollar notes are not immediately available, or time will not permit the holder's old dollar notes or other required documents to reach the dollar exchange agent before the expiration date, or the procedure for book-entry transfer described above cannot be completed on a timely basis, a tender may nonetheless be made if:

•

the tender is made through an eligible institution;



•

prior to the expiration date, the dollar exchange agent received from an eligible institution a properly completed and duly executed letter of transmittal, or a facsimile of the letter of transmittal, and notice of guaranteed delivery, substantially in the form provided by us, by facsimile transmission, mail or hand delivery,



(1)

stating the name and address of the holder of old dollar notes and the amount of old dollar notes tendered;



(2)

stating that the tender is being made; and



(3)

guaranteeing that within three New York Stock Exchange trading days after the expiration date, the certificates for all physically tendered old dollar notes, in proper form for transfer, or a book-entry confirmation, as the case may be, and any other documents required by the letter of transmittal will be deposited by the eligible institution with the dollar exchange agent; and



•

the certificates for all physically tendered old dollar notes, in proper form for transfer, or a book-entry confirmation, as the case may be, and all other documents required by the letter of transmittal, are received by the exchange dollar agent within three New York Stock Exchange trading days after the expiration date.

Withdrawal Rights

        You may withdraw tenders of your old notes at any time prior to 5:00 p.m., New York City time, on the expiration date.

        For a withdrawal to be effective, you must send a written notice of withdrawal to the appropriate exchange agent at such exchange agent's corresponding address set forth below under "—The Exchange Agents." Any such notice of withdrawal must:

(1)

specify the name of the person having tendered the old notes to be withdrawn;



(2)

identify the old notes to be withdrawn, including the principal amount of such old notes; and



(3)

where certificates for old notes are transmitted, specify the name in which old notes are registered, if different from that of the withdrawing holder.

        If certificates for old notes have been delivered or otherwise identified to an exchange agent, then, prior to the release of such certificates the withdrawing holder must also submit the serial numbers of the particular certificates to be withdrawn and signed notice of withdrawal with signatures guaranteed by an eligible institution, unless such holder is an eligible institution. If old notes have been tendered pursuant to the procedure for book-entry transfer or the blocking instructions described above, any notice of withdrawal must specify the name and number of the account at DTC or Euroclear or

33

Clearstream, Luxembourg, as applicable, to be credited with the withdrawn old notes and otherwise comply with the procedures of such facility. We will determine all questions as to the validity, form and eligibility (including time of receipt) of such notices and our determination will be final and binding on all parties. Any tendered old notes so withdrawn will be deemed not to have been validly tendered for exchange for purposes of this exchange offer. Any old notes tendered for exchange that are not exchanged for any reason will be returned to the holder without cost to such holder. In the case of old notes tendered by book-entry transfer into the exchange agent's account at DTC, such old notes will be credited to an account maintained with DTC for the old notes as soon as practicable after withdrawal, rejection of tender or termination of this exchange offer. In the case of old euro notes tendered in accordance with the blocking procedures of Euroclear or Clearstream, Luxembourg, the old euro notes will be returned to their holder by cancellation of the blocking instruction in accordance with the standard operating procedures of Euroclear or Clearstream, Luxembourg as soon as practicable after withdrawal, rejection of tender or termination of this exchange offer. Properly withdrawn old notes may be re-tendered by following one of the procedures described under "—How to Tender Old Notes for Exchange" above at any time on or prior to 5:00 p.m., New York City time, on the expiration date.

Conditions to the Exchange Offer

        Notwithstanding any other provision of this exchange offer, we will not be required to accept for exchange, or to issue new notes in this exchange offer for any old notes, and we may terminate or amend this exchange offer, if at any time before the expiration of this exchange offer:

(1)

any federal law, statute, rule or regulation shall have been adopted or enacted which, in our judgment, would reasonably be expected to impair our ability to proceed with this exchange offer;



(2)

any stop order shall be threatened or in effect with respect to the registration statement of which this prospectus constitutes a part or the qualification of the indenture under the Trust Indenture Act of 1939, as amended;



(3)

there shall occur a change in the current interpretation by the staff of the SEC which permits the new notes issued in this exchange offer in exchange for the old notes to be offered for resale, resold and otherwise transferred by such holders, other than broker-dealers and any such holder which is an "affiliate" of our company within the meaning of Rule 405 under the Securities Act, without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such new notes acquired in this exchange offer are acquired in the ordinary course of such holder's business and such holder has no arrangement or understanding with any person to participate in the distribution of such new notes issued in this exchange offer;



(4)

there has occurred any general suspension of or general limitation on prices for, or trading in, securities on any national exchange or in the over-the-counter market;



(5)

any governmental agency creates limits that adversely affect our ability to complete this exchange offer; or



(6)

there shall occur any declaration of war, armed hostilities or other similar international calamity directly or indirectly involving the United States, or the worsening of any such condition that existed at the time that we commence this exchange offer.

        The non-occurrence of each of the preceding events is a condition to this exchange offer. We expressly reserve the right to amend or terminate this exchange offer upon the occurrence of any of these events. The conditions are for our sole benefit and we may assert them regardless of the circumstances giving rise to them. We may waive the preceding conditions in whole or in part at any time and from time to time in our sole discretion prior to the expiration of this exchange offer. If we

34

do so, this exchange offer will remain open for at least three (3) business days following any waiver of the preceding conditions and, if we determine that any waiver constitutes a material change to the terms of this exchange offer, this exchange offer will remain open for at least five (5) business days following any such waiver. Our failure at any time to exercise the foregoing rights shall not be deemed a waiver of any such right and each such right shall be deemed an ongoing right which we may assert at any time and from time to time, except that all conditions to this exchange offer must be satisfied or waived by us prior to the expiration of this exchange offer. We will give oral or written notice or public announcement of any waiver by us of any condition and any related amendment, termination or extension of this exchange offer. In the case of any extension, such oral or written notice or public announcement will be issued no later than 9:00 a.m., New York City time, on the business day after the previously scheduled expiration date.

35

The Exchange Agents

        As explained above, we have appointed two separate exchange agents in connection with this exchange offer. Wells Fargo Bank, N.A has been appointed as the dollar exchange agent and is responsible for the tender and exchange of all old dollar notes for new dollar notes. Citibank, N.A. has been appointed as the euro exchange agent and is responsible for the tender and exchange of all old euro notes for new euro notes. All executed letters of transmittal should be directed to the appropriate exchange agent at the address set forth below corresponding to such exchange agent. You should direct questions and requests for assistance, requests for additional copies of this prospectus or of the letter of transmittal and requests for notices of guaranteed delivery to the relevant exchange agent addressed as follows:

36

        Delivery of the letter of transmittal to the wrong exchange agent, to an address other than as set forth above, or transmission of such letter of transmittal via facsimile other than as set forth above, does not constitute a valid delivery of such letter of transmittal.

Fees and Expenses

        We will not make any payment to brokers, dealers or others soliciting acceptance of this exchange offer, except for reimbursement of mailing expenses.

Accounting Treatment

        We will not recognize any gain or loss for accounting purposes upon the consummation of this exchange offer. We will amortize the expense of this exchange offer over the term of the new notes in accordance with accounting principles generally accepted in the United States of America.

Transfer Taxes

        You will not be obligated to pay any transfer taxes in connection with the tender of your old notes in this exchange offer. If, however, new notes are to be delivered to, or are to be issued in the name of, any person other than the holder of the old notes tendered, or if a transfer tax is imposed for any reason other than the exchange of old notes in connection with this exchange offer, then you must pay any such transfer taxes, whether imposed on the registered holder or on any other person. If satisfactory evidence of payment of, or exemption from, such taxes is not submitted with the letter of transmittal, the amount of such transfer taxes will be billed directly to you.

Consequences of Failing to Exchange Old Notes

        Holders who desire to tender their old notes in exchange for new notes registered under the Securities Act should allow sufficient time to ensure timely delivery. Neither of the exchange agents nor our Company is under any duty to give notification of defects or irregularities with respect to the tenders of old notes for exchange.

        Old notes that are not tendered or are tendered but not accepted will, following the consummation of this exchange offer, continue to be subject to the provisions in the indenture regarding the transfer and exchange of the old notes and the existing restrictions on transfer set forth in the legend on the old notes and in the offering memorandum dated December 3, 2004, relating to the old notes. Except in limited circumstances with respect to specific types of holders of old notes, we will have no further obligation to provide for the registration under the Securities Act of such old notes. In general, old notes, unless registered under the Securities Act, may not be offered or sold except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. We do not currently anticipate that we will take any action to register the untendered old notes under the Securities Act or under any state securities laws.

        Upon completion of this exchange offer, holders of the old notes will not be entitled to any further registration rights under the exchange and registration rights agreement, except under limited circumstances.

        Holders of the new notes and any old notes which remain outstanding after consummation of this exchange offer will vote together as a single class for purposes of determining whether holders of the requisite percentage of the class have taken certain actions or exercised certain rights under the indenture.

Consequences of Exchanging Old Notes

        Based on interpretations of the staff of the SEC, as set forth in no-action letters to third parties, we believe that the new notes may be offered for resale, resold or otherwise transferred by holders of such notes, other than by any holder which is a broker-dealer or an "affiliate" of our Company within the meaning of Rule 405 under the Securities Act. The new notes may be offered for resale, resold or otherwise transferred without compliance with the registration and prospectus delivery provisions of the Securities Act, if:

(1)

the new notes are acquired in the ordinary course of such holder's business; and



(2)

such holder has no arrangement or understanding with any person to participate in the distribution of the new notes.

        However, the SEC has not considered this exchange offer in the context of a no-action letter, and we cannot guarantee that the staff of the SEC would make a similar determination with respect to this exchange offer as in such other circumstances.

        Each holder, other than a broker-dealer, must furnish a written representation, at our request, that:

(1)

it is not an affiliate of ours;



(2)

it is not engaged in, and does not intend to engage in, a distribution of the new notes and has no arrangement or understanding to participate in a distribution of the new notes;



(3)

it is acquiring the new notes in the ordinary course of its business; and



(4)

it is not acting on behalf of a person who could not make representations (1)-(3).

        Each broker-dealer that receives new notes in this exchange offer for its own account in exchange for old notes must acknowledge that it acquired such old notes as a result of market-making or other trading activities and that it will deliver a prospectus in connection with any resale of the new notes. See "Plan of Distribution" for a discussion of the exchange and resale obligations of broker-dealers in connection with this exchange offer.

        In addition, to comply with state securities laws of certain jurisdictions, the new notes may not be offered or sold in any state, unless they have been registered or qualified for sale in such state or an exemption from registration or qualification is available and complied with by the holders selling the new notes. We have agreed in the exchange and registration rights agreement that, prior to any public offering of transfer restricted securities, we will register or qualify the transfer restricted securities for offer or sale under the securities laws of any jurisdiction requested by a holder. Unless a holder requests, we currently do not intend to register or qualify the sale of the new notes in any state where an exemption from registration or qualification is required and not available. "Transfer restricted securities" means each old note until:

(1)

the date on which such old note has been exchanged by a person other than a broker-dealer or an affiliate for a new note;



(2)

following the exchange by a broker-dealer in this exchange offer of an old note for a new note, the date on which the new note is sold to a purchaser who receives from such broker-dealer on or prior to the date of such sale a copy of this prospectus;



(3)

the date on which such old note has been effectively registered under the Securities Act and disposed of in accordance with a shelf registration statement that we file in accordance with the exchange and registration rights agreement; or

38

(4)

the date on which such old note is distributed to the public in a transaction under Rule 144 of the Securities Act.

USE OF PROCEEDS

        We will not receive any cash proceeds from the issuance of the new notes. In consideration for issuing the new notes as contemplated in this prospectus, we will receive in exchange old notes in like principal amount, which will be cancelled and, as such, will not result in any increase in our indebtedness.

        The aggregate net proceeds received by us from the sale of the old notes, after deducting the initial purchasers' discounts and commissions and offering expenses, were approximately 355 million U.S. dollar equivalents in cash. We used all of the net proceeds to redeem part of our outstanding 10.125% senior subordinated notes due 2009.

RATIO OF EARNINGS TO FIXED CHARGES

        The following table shows our consolidated ratio of earnings to fixed charges for the periods indicated (dollars in millions):

SELECTED HISTORICAL FINANCIAL DATA

        The selected historical financial data set forth below presents our historical financial data and the historical financial data as of and for the dates and periods indicated. Effective August 16, 2005, as a result of the HLLC Merger, we have consolidated the financial results of Huntsman LLC. At the same time, HIH was also merged into our Company. Effective December 20, 2005, as a result of the AdMat Minority Interest Transaction, we have consolidated the financial results of AdMat. Huntsman LLC and AdMat came under common control with us effective May 1, 2003 and June 30, 2003, respectively. HIH and our Company have been under common control since our inception. The financial data presented herein reflect the financial position, results of operations and cash flows as if HIH, Huntsman LLC, AdMat and our Company were combined for all periods for which they were under common control. As a result, the financial information as of and for the years ended December 31, 2003, 2002 and 2001 is not comparable to the financial information as of and for the years ended December 31, 2005 and 2004. You should review the selected financial data in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations" and our Consolidated Financial Statements and accompanying notes included elsewhere in this prospectus.

(a)

During the fourth quarter of 2005, we adopted Financial Accounting Standards Board ("FASB") Interpretation No. ("FIN") 47, "Accounting for Conditional Asset Retirement Obligations," and recorded a charge for the cumulative effect of accounting change, net of tax, of $31.7 million. Also in the fourth quarter of 2005, we accelerated the date for actuarial measurement of our pension and postretirement benefit obligations from December 31 to November 30. The effect of the change in measurement date resulted in a cumulative effect of accounting change credit, net of tax, of $4.2 million. In 2001, we adopted SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities," resulting in a cumulative increase in net loss of $1.5 million.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

        The following discussion and analysis should be read in conjunction with the historical financial statements and other financial information appearing elsewhere in the prospectus, including "Prospectus Summary—Summary Historical Financial Data," "Capitalization" and "Selected Historical Financial Data."

Overview

        We are among the world's largest global manufacturers of differentiated and commodity chemical products. We manufacture a broad range of chemical products and formulations, which we market in more than 100 countries to a diversified group of consumer and industrial customers. Our products are used in a wide range of applications, including those in the adhesives, aerospace, automotive, construction products, durable and non-durable consumer products, electronics, medical, packaging, paints and coatings, power generation, refining and synthetic fiber industries. We are a leading global producer in many of our key product lines, including MDI, amines, surfactants, epoxy-based polymer formulations, maleic anhydride and titanium dioxide. Our administrative, research and development and manufacturing operations are primarily conducted at the 67 facilities that we own or lease. Our facilities are located in 24 countries and we employ approximately 10,800 associates worldwide. Our businesses benefit from significant vertical integration, large production scale and proprietary manufacturing technologies, which allow us to maintain a low-cost position. We had revenues for the year ended December 31, 2005 and 2004 of $13.0 billion and $11.4 billion, respectively.

        Our business is organized around our six segments: Polyurethanes, Advanced Materials, Performance Products, Pigments, Polymers and Base Chemicals. These segments can be divided into two broad categories: differentiated and commodity. Our Polyurethanes, Advanced Materials and Performance Products segments produce differentiated products, and our Pigments, Polymers and Base Chemicals segments produce commodity chemicals. Among our commodity products, our Pigments business, while cyclical, is influenced largely by seasonal demand patterns in the coatings industry. Certain products in our Polymers segment also follow different trends than petrochemical commodities as a result of our niche marketing strategy for such products that focuses on supplying customized formulations. Nevertheless, each of our six operating segments is impacted to some degree by economic conditions, prices of raw materials and global supply and demand pressures.

        Growth in our Polyurethanes and Advanced Materials segments has been driven by the continued substitution of our products for other materials across a broad range of applications as well as the level of global economic activity. Historically, demand for many of these products has grown at rates in excess of GDP growth. In Polyurethanes, this growth, particularly in Asia, has recently resulted in improved demand and higher industry capacity utilization rates for many of our key products, including MDI. In 2005, the profitability of our Polyurethanes and Advanced Materials segments improved due to increased demand in several of our key industrial end markets, including aerospace, automotive and construction products. This has allowed us to increase selling prices, which has more than offset increases in the cost of our primary raw materials, including benzene, propylene and chlorine.

        The global PO market is influenced by supply and demand imbalances. PO demand is largely driven by growth in the polyurethane industry, and, as a result, growth rates for PO have generally exceeded GDP growth rates. As a co-product of our PO manufacturing process, we also produce MTBE. MTBE is an oxygenate that is blended with gasoline to reduce harmful vehicle emissions and to enhance the octane rating of gasoline. See "Business—Environmental, Health and Safety Matters—MTBE Developments" and "Risk Factors" for a discussion of legal and regulatory developments that have resulted in the curtailment and potential elimination of MTBE in gasoline in the U.S. and elsewhere. We have announced the sale of our U.S. butadiene and MTBE business operated in our

42

Base Chemicals segment; however, the PO/MTBE operations in our Polyurethanes segment are not included in this transaction which is expected to close in mid-2006. See "Business—Recent Developments—Pending Sale of U.S. Butadiene and MTBE Business."

        In 2005, we marketed approximately 95% of our MTBE to customers located in the U.S. for use as a gasoline additive. Most of our 2005 sales of MTBE to U.S. customers were made pursuant to long-term agreements. During 2006 (and concluding by the first quarter of 2007), our long-term MTBE sales agreements will terminate. We anticipate that our 2006 sales of MTBE in the U.S. will decrease substantially as compared to 2005 levels. Nevertheless, we expect to continue to sell a portion of our MTBE into the U.S. market, although not pursuant to any new long-term agreements. We have entered into sales agreements to sell a significant percentage of our MTBE into the Latin American market, and we currently believe that we could also sell MTBE relatively efficiently in Europe and Asia. Nevertheless, as a result of varying market prices and transportation costs, sales of MTBE in markets outside the U.S. may produce lower margins than the sale of MTBE in the U.S. We may also elect to use all or a portion of our precursor TBA to produce saleable products other than MTBE. If we opt to produce products other than MTBE, necessary modifications to our facilities will require us to make significant capital expenditures and the sale of such other products may produce a lower level of cash flow than the sale of MTBE.

        In our Performance Products segment, demand for our performance specialties has generally continued to grow at rates in excess of GDP as overall demand is significantly influenced by new product and application development. Overall demand for most of our performance intermediates has generally been stable or improving, but excess surfactant manufacturing capacity in Europe and a decline in the use of LAB in new detergent formulations have continued to impair our ability to increase prices in response to higher raw material costs. EG industry operating rates and profitability have declined sharply during 2005 due to additional capacity coming on stream.

        Historically, demand for titanium dioxide pigments has grown at rates approximately equal to global GDP growth. Pigment prices have historically reflected industry-wide operating rates but have typically lagged behind movements in these rates by up to twelve months due to the effects of product stocking and destocking by customers and producers, contract arrangements and seasonality. The industry experiences some seasonality in its sales because sales of paints, the largest end use for titanium dioxide, generally peak during the spring and summer months in the northern hemisphere. This results in greater sales volumes in the second and third quarters of the year.

        The profitability of our Polymers and Base Chemicals segments has historically been cyclical in nature. The industry has recently operated in an up cycle that resulted primarily from strong demand reflecting global economic conditions and the fact that there have been no recent North American or European capacity additions. However, volatile crude oil and natural gas-based raw materials costs and a recent weakening in demand could negatively impact the profitability of our Polymers and Base Chemicals segments.

        For a discussion of recent developments affecting our Company, see "Business—Recent Developments" below.

Outlook

        We are optimistic about our outlook for 2006 and, consistent with industry analysts, we believe that the outlook for the chemical industry is generally positive. We expect that demand for most of our differentiated products will remain strong but anticipate somewhat softer demand for certain of our commodity products in the first half of 2006. We are currently experiencing less volatility in energy and raw material prices; however, we remain concerned that sustained high energy and raw material costs or volatility in such costs may add uncertainty to the chemical industry's profit outlook for 2006.

43

        We believe that price momentum is generally favorable. We announced significant price increases for many of our products in the fourth quarter of 2005, and we expect our differentiated products to maintain price momentum in the near term. We believe that price momentum in our commodities products is less favorable, and we expect that the margin weakness that we experienced in the later half of 2005 in our European petrochemicals business is likely to continue into early 2006. We believe that regional capacity additions in most of our commodity businesses will be limited over the next several years.

        We believe that any lingering effects from the 2005 U.S. Gulf Coast storms on logistics and raw material supplies are dissipating, and we expect that any further storm related effects will be relatively modest. We also believe that the supply and demand imbalances created by these storms have largely been resolved as the affected production capacity has now mostly restarted.

        We expect continued global GDP growth, but we also believe that sustained high energy costs have the potential to dampen economic growth.

Results of Operations

        The following sets forth the condensed consolidated results of operations for the years ended December 31, 2005, 2004 and 2003 (dollars in millions):

NM—Not meaningful

45

        Included in EBITDA are the following items of (expense) income:

(1)

Includes a tax benefit of $3.3 million in 2005 on the cumulative effect of changes in accounting principle.

(2)

EBITDA is defined as net income (loss) before interest, income taxes, depreciation and amortization. We believe that EBITDA enhances an investor's understanding of our financial performance and our ability to satisfy principal and interest obligations with respect to our indebtedness. However, EBITDA should not be considered in isolation or viewed as a substitute for net income, cash flow from operations or other measures of performance as defined by generally accepted accounting principles in the U.S. ("GAAP"). Moreover, EBITDA as used herein is not necessarily comparable to other similarly titled measures of other companies due to potential inconsistencies in the method of calculation. Our management uses EBITDA to assess financial performance and debt service capabilities. In assessing financial performance, our management reviews EBITDA as a general indicator of economic performance compared to prior periods. Because EBITDA excludes interest, income taxes, depreciation and amortization, EBITDA provides an indicator of general economic performance that is not affected by debt restructurings, fluctuations in interest rates or effective tax rates, or levels of depreciation and amortization. Accordingly, our management believes this type of measurement is useful for comparing general operating performance from period to period and making certain related management decisions. EBITDA is also used by securities analysts, lenders and others in their evaluation of different companies because it excludes certain items that can vary widely across different industries or among companies within the same industry. For example, interest expense can be highly dependent on a company's capital structure, debt levels and credit ratings. Therefore, the impact of interest expense on earnings can vary significantly among companies. In addition, the tax positions of companies can vary because of their differing abilities to take advantage of tax benefits and because of the tax policies of the various jurisdictions in which they operate. As a result, effective tax rates and tax expense can vary considerably among companies. Finally, companies employ productive assets of different ages and utilize different methods of acquiring and depreciating such assets. This can result in considerable variability in the relative costs of

46

productive assets and the depreciation and amortization expense among companies. Our management also believes that our investors use EBITDA as a measure of our ability to service indebtedness as well as to fund capital expenditures and working capital requirements. Nevertheless, our management recognizes that there are material limitations associated with the use of EBITDA in the evaluation of our Company as compared to net income, which reflects overall financial performance, including the effects of interest, income taxes, depreciation and amortization. EBITDA excludes interest expense. Because we have borrowed money in order to finance our operations, interest expense is a necessary element of our costs and ability to generate revenue. Therefore, any measure that excludes interest expense has material limitations. EBITDA also excludes taxes. Because the payment of taxes is a necessary element of our operations, any measure that excludes tax expense has material limitations. Finally, EBITDA excludes depreciation and amortization expense. Because we use capital assets, depreciation and amortization expense is a necessary element of our costs and ability to generate revenue. Therefore, any measure that excludes depreciation and amortization expense has material limitations. Our management compensates for the limitations of using EBITDA by using it to supplement GAAP results to provide a more complete understanding of the factors and trends affecting the business than GAAP results alone. Our management also uses other metrics to evaluate capital structure, tax planning and capital investment decisions. For example, our management uses credit ratings and net debt ratios to evaluate capital structure, effective tax rate by jurisdiction to evaluate tax planning, and payback period and internal rate of return to evaluate capital investments. Our management also uses trade working capital to evaluate its investment in accounts receivable and inventory, net of accounts payable.

We believe that net income (loss) is the performance measure calculated and presented in accordance with GAAP that is most directly comparable to EBITDA and that cash provided by operating activities is the liquidity measure calculated and presented in accordance with GAAP

47

that is most directly comparable to EBITDA. The following table reconciles EBITDA to our net income (loss) and to our cash provided by operations:
