Dear Sirs and Mesdames:

Headwaters Incorporated, a Delaware corporation (the “Company”), proposes to issue and sell to the several purchasers named in Schedule I hereto (the “Initial Purchasers”) $135,000,000 principal amount of its 2.50% Convertible Senior Subordinated Notes due 2014 (the “Firm Securities”) to be issued pursuant to the provisions of an Indenture to be dated as of 22, 2007 (the “Indenture”) between the Company and ▇▇▇▇▇ Fargo Bank, National Association, as Trustee (the “Trustee”). The Company also proposes to issue and sell to the several Initial Purchasers not more than an additional $25.0 million principal amount of its 2.50% Convertible Senior Subordinated Notes due 2014 (the “Additional Securities”) if and to the extent that the Representatives (as defined below) shall have determined to exercise, on behalf of the Initial Purchasers, the right to purchase such Additional Securities (or any portion thereof) granted in Section 2 hereof. The Firm Securities and the Additional Securities are hereinafter collectively referred to as the “Securities.” The Securities will be convertible into cash and shares of common stock of the Company, par value $0.001 per share (the “Common Stock”). The shares into which the Securities are convertible are hereinafter collectively referred to as the “Underlying Securities.” ▇.▇. ▇▇▇▇▇▇ Securities Inc., Deutsche Bank Securities Inc. and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated shall act as representatives (collectively, the “Representatives”) of the several Initial Purchasers.

The Securities will be offered without being registered under the Securities Act of 1933, as amended (the “Securities Act”), to qualified institutional buyers in compliance with the exemption from registration provided by Rule 144A under the Securities Act.

Holders (including subsequent transferees) of the Securities will have benefit of the registration rights set forth in the registration rights agreement (the “Registration Rights Agreement”), for so long as such Securities constitute Transfer Restricted Securities (as defined in the Registration Rights Agreement). This Agreement, the Securities, the Indenture and the Registration Rights Agreement are hereinafter referred to collectively as the “Operative Documents.” This is to confirm the agreements concerning the purchase of the Securities from the Company by the Initial Purchasers.

In connection with the sale of the Securities, the Company has prepared a preliminary offering memorandum dated January 16, 2007, (the “Preliminary Offering Memorandum”) and a Pricing Supplement dated January 16, 2007, describing the terms of the Securities and set forth on Schedule II hereto (the “Pricing Supplement”), and will prepare a final offering memorandum (the “Final Offering Memorandum” and, together with the Preliminary Offering Memorandum, the “Offering Documents”) including or incorporating by reference a description of the terms of the Securities, the terms of the offering and a description of the Company. As used herein, the term “Offering Documents” shall include in each case the documents incorporated by reference therein. The terms “supplement,” “amendment” and “amend” as used herein with respect to an Offering Document shall include all documents deemed to be incorporated by reference in the Preliminary Offering Memorandum or Final Offering Memorandum that are filed subsequent to the date of such Offering Document with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”). “Time of Sale Memorandum” means the Preliminary Offering Memorandum and the Pricing Supplement together with the information in the form set forth on Schedule II hereto that has been prepared and delivered by the Company to the Initial Purchasers in connection with the offering and sale of the Securities. “Applicable Time” means 5:00 p.m. Eastern Standard Time on January 16, 2007.

On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Company agrees to issue and sell to the Initial Purchasers the Additional Securities, and the Initial Purchasers shall have the right to purchase, severally and not jointly, up to $25.0 million principal amount of Additional Securities at the purchase price set forth above plus accrued interest, if any, to the date of payment and delivery. The Initial Purchasers may exercise these rights in whole or from time to time in part by giving written notice of each election to exercise the foregoing option not later than 13 days after the date of this Agreement.

such adjustments to eliminate fractional securities as you may determine) that bears the same proportion to the total number of Additional Securities to be purchased on such Option Closing Date as the principal amount of Firm Securities set forth in Schedule I hereto opposite the name of such Initial Purchaser bears to the total principal amount of Firm Securities.

The Company hereby agrees that, without the prior written consent of ▇.▇. ▇▇▇▇▇▇ Securities Inc., Deutsche Bank Securities Inc. and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated on behalf of the Initial Purchasers, it will not, during the period ending 90 days after the date of the Final Offering Memorandum, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, (ii) file any registration statement with the Commission relating to the offering of any shares of Common Stock, (iii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction in clause (i), (ii) or (iii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, or (iv) publicly announce an intention to effect any such transaction in clause (i), (ii) or (iii).

The foregoing paragraph shall not apply to (i) the Securities to be sold hereunder or the Underlying Securities, (ii) the issuance by the Company of shares of Common Stock upon the exercise of an option, warrant or note or the conversion of a security outstanding on the date hereof of which the Initial Purchasers have been advised in writing, (iii) the commencement of an exchange offer for the Company’s existing 2⅞% Convertible Senior Subordinated Notes due 2016 and the issuance of the related convertible notes in connection with such exchange offer, (iv) the filing of registration statements in respect of the Securities and the Underlying Securities or in connection with clause (iii) above or Forms S-8, (v) the issuance of shares of Common Stock or rights to acquire shares of Common Stock in respect of securities offered pursuant to the terms of the Company’s existing employee benefits plans or agreements, or (vi) transfers or sales of shares of Common Stock pursuant to the convertible note hedge and warrant transactions executed by the Company on the date hereof.

3. Terms of Offering. The Company is advised by you that the Initial Purchasers will make an offering of the Securities purchased by the Initial Purchasers hereunder on the terms set forth in this Agreement and to be set forth in the Final Offering Memorandum, as soon as practicable after this Agreement is entered into as in your judgment is advisable.

4. Payment and Delivery. Payment for the Firm Securities shall be made to the Company in Federal or other funds immediately available in New York City against delivery of such Firm Securities for the respective accounts of the several Initial Purchasers at 9:00 a.m., New York City time, on January 22, 2007, or at such other time on the same or such other date as shall be designated in writing by you. The time and date of such payment are hereinafter referred to as the “Closing Date.”

The certificates evidencing the Firm Securities and the Additional Securities shall be delivered to you on the Closing Date for the respective accounts of the several Initial Purchasers, with any transfer taxes payable in connection with the transfer of the Securities to the Initial Purchasers duly paid, against payment of the Purchase Price therefor.

The Company shall not be required to qualify as a foreign corporation or to take any action that would subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation as a foreign corporation. The Company will advise the Initial Purchasers promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Securities for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Company shall use its best efforts to obtain the withdrawal thereof at the earliest possible moment.

(f) To make generally available to the Company’s security holders and to you as soon as practicable an earning statement covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the date of this Agreement that satisfies the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder.

(g) For a period of five years after the Closing Date, to furnish to you and, upon request, to each Initial Purchaser, copies of all annual reports, quarterly reports and current reports filed with the Commission on Forms 10-K, 10-Q and 8-K, or such other similar forms as may be designated by the Commission, and such other documents, reports and information as shall be furnished by the Company to its stockholders generally.

(h) Neither the Company nor any Affiliate will sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in the Securities Act) which could be integrated with the sale of the Securities in a manner which would require the registration under the Securities Act of the Securities.

(i) Not to solicit any offer to buy or offer or sell the Securities by means of any form of general solicitation or general advertising (as those terms are used in Regulation D under the Securities Act) or in any manner involving a public offering within the meaning of Section 4(2) of the Securities Act.

(j) While any of the Securities remain “restricted securities” within the meaning of the Securities Act, to make available, upon request, to any seller of such Securities the information specified in Rule 144A(d)(4) under the Securities Act, unless the Company is then subject to Section 13 or 15(d) of the Exchange Act.

(k) If requested by you, to use its best efforts to permit the Securities to be designated PORTAL securities in accordance with the rules and regulations adopted by the National Association of Securities Dealers, Inc. relating to trading in the PORTAL Market.

(l) During the period of two years after the Closing Date, the Company will not, and will not permit any of its affiliates (as defined in Rule 144 under the Securities Act) to resell any of the Securities which constitute “restricted securities” under Rule 144 that have been reacquired by any of them.

(m) Not to take any action prohibited by Regulation M under the Exchange Act in connection with the distribution of the Securities contemplated hereby.

(n) To use best efforts to have the Underlying Securities listed on the New York Stock Exchange.

7. Expenses. Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, the Company agrees to pay or cause to be paid all expenses incident to the performance of its obligations under this Agreement, including: (i) the fees, disbursements and expenses of the Company’s counsel and the Company’s accountants in connection with the issuance and sale of the Securities and all other fees or expenses in connection with the preparation of each Offering Document and all amendments and supplements thereto, all printing costs associated therewith, and the mailing and delivering of copies thereof to the Initial Purchasers and dealers, in the quantities hereinabove specified, (ii) all costs and expenses related to the transfer and delivery of the Securities to the Initial Purchasers, including any transfer or other taxes payable thereon, (iii) the cost of printing or producing any Blue Sky or legal investment memorandum in connection with the offer and sale of the Securities under state securities laws and all expenses in connection with the qualification of the Securities for offer and sale under state securities laws as provided in Section 6(e) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Initial Purchasers in connection with such qualification and in connection with the Blue Sky or legal investment memorandum, (iv) any fees charged by rating agencies for the rating of the Securities, (v) all fees and expenses, if any, incurred in connection with the admission of the Securities for trading in PORTAL or any appropriate market system, (vi) the cost of preparation, issuance and delivery of the Securities, including the cost of printing certificates representing the Securities, (vii) the costs and charges of any trustee, transfer agent, registrar or depositary, (viii) the costs and expenses of the Company relating to investor presentations on any “road show” undertaken in connection with the marketing of the offering of the Securities, including, without limitation, expenses associated with the preparation or dissemination of any electronic road show, reasonable expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the prior approval of the Company, travel and lodging expenses of the representatives and officers of the Company and any such consultants, and half of the cost of any aircraft chartered in connection with the road show, provided such charter is approved by the Company, (ix) the document and production charges and expenses associated with printing this Agreement and (x) all other costs and expenses incident to the performance of the obligations of the Company hereunder for which provision is not otherwise made in this Section. It is understood, however, that except as provided in this Section, Section 9 entitled “Indemnity and Contribution”, and the last paragraph of Section 11 below, the Initial Purchasers will pay all of their costs and expenses, including fees and disbursements of their counsel, stock transfer taxes payable on resale of any of the Securities by them and any advertising expenses connected with any offers they may make.

8. Offering of Securities; Restrictions on Transfer. Each Initial Purchaser, severally and not jointly, represents and warrants that such Initial Purchaser is a qualified institutional buyer as defined in Rule 144A under the Securities Act (a “QIB”). Each Initial Purchaser, severally and not jointly, agrees with the Company that (i) it will not solicit offers for, or offer or sell, such Securities by any form of general solicitation or general advertising (as those terms are used in Regulation D under the Securities Act) or in any manner involving a public offering within the meaning of Section 4(2) of the Securities Act and (ii) it will solicit offers for such Securities only from, and will offer such Securities only to, persons that it reasonably believes to be QIBs that in purchasing such Securities are deemed to have represented

and agreed as provided in the Final Offering Memorandum under the caption “Transfer Restrictions”.

9. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless each Initial Purchaser, each person, if any, who controls any Initial Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and each affiliate of any Initial Purchaser within the meaning of Rule 405 under the Securities Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Time of Sale Memorandum or the Final Offering Memorandum or any amendments or supplements thereto, or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein in the light of circumstances under which they were made not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Initial Purchaser furnished to the Company in writing by such Initial Purchaser through you expressly for use therein.

(b) Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Time of Sale Memorandum or the Final Offering Memorandum or any amendments or supplements thereto, or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein in the light of circumstances under which they were made not misleading, but only with reference to information relating to such Initial Purchaser furnished to the Company in writing by such Initial Purchaser through you expressly for use in the Time of Sale Memorandum and the Final Offering Memorandum or any amendments or supplements thereto.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 9(a) or 9(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the

indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Representatives, in the case of parties indemnified pursuant to Section 9(a), and by the Company, in the case of parties indemnified pursuant to Section 9(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) To the extent the indemnification provided for in Section 9(a) or 9(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Initial Purchasers on the other hand from the offering of the Securities or (ii) if the allocation provided by clause 9(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 9(d)(i) above but also the relative fault of the Company on the one hand and of the Initial Purchasers on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Initial Purchasers on the other hand in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Securities (before deducting expenses) received by the Company and the total discounts and commissions received by the Initial Purchasers, as set forth in the Final Offering Memorandum, bear to the aggregate offering price of the Securities. The relative fault of each of the Company on the one hand and of the Initial Purchasers on the other hand shall be determined by

reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Initial Purchasers’ respective obligations to contribute pursuant to this Section 9 are several in proportion to the respective principal amount of Securities they have purchased hereunder, and not joint.

(e) The Company and each of the Initial Purchasers agree that it would not be just or equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 9(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 9(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9, no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Securities resold by it in the initial placement of such Securities were offered to the investors exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 9 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Initial Purchaser, any person controlling any Initial Purchaser or any affiliate of any Initial Purchaser or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Securities.

10. Termination. The Initial Purchasers may terminate this Agreement by notice given by you to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange, the Nasdaq National Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in your judgment,

is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Securities on the terms and in the manner contemplated in the Time of Sale Memorandum or the Final Offering Memorandum.

11. Effectiveness; Defaulting Initial Purchasers. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Initial Purchasers shall fail or refuse to purchase Securities that it has or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of the Firm Securities to be purchased on such date, the other Initial Purchasers shall be obligated severally in the proportions that the number of Firm Securities set forth opposite their respective names in Schedule I bears to the aggregate principal amount of Securities set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as you may specify, to purchase the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Securities that any Initial Purchaser has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 11 by an amount in excess of one-ninth of such number of Securities without the written consent of such Initial Purchaser. If, on the Closing Date, any Initial Purchaser or Initial Purchasers shall fail or refuse to purchase Firm Securities which it or they have agreed to purchase hereunder on such date and the aggregate principal amount of Firm Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Firm Securities to be purchased on such date, and arrangements satisfactory to you and the Company for the purchase of such Firm Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser or of the Company. In any such case either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Time of Sale Memorandum or the Final Offering Memorandum, or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Initial Purchaser or Initial Purchasers shall fail or refuse to purchase Additional Securities and the aggregate principal amount of Additional Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Additional Securities to be purchased on such Option Closing Date, the non-defaulting Initial Purchasers shall have the option to (i) terminate their obligation hereunder to purchase the Additional Securities to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Securities that such non-defaulting Initial Purchasers would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

If this Agreement shall be terminated by the Initial Purchasers, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, excluding any termination pursuant to clauses (i), (iii), (iv) or (v) of Section 11, or if for any reason, the Company shall be unable to perform its

obligations under this Agreement, the Company will reimburse the Initial Purchasers or such Initial Purchasers as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Initial Purchasers in connection with this Agreement or the offering contemplated hereunder.

12. Entire Agreement. This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Securities, represents the entire agreement between the Company, on the one hand, and the Initial Purchasers, on the other, with respect to the preparation of the Offering Document, the conduct of the offering, and the purchase and sale of the Securities.

13. No Fiduciary Duties. The Company acknowledges and agrees that the Initial Purchasers are acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as financial advisors or fiduciaries to, or agents of, the Company or any other person. Additionally, neither the Representatives nor any other Initial Purchaser is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with their own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated hereby, and neither the Representatives nor any other Initial Purchaser shall have any responsibility or liability to the Company with respect thereto. Any review by the Representatives or any Initial Purchaser of the Company and the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Representatives or such Initial Purchaser, as the case may be, and shall not be on behalf of the Company or any other person.

14. Counterparts. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

15. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

16. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

17. Notices. All communications hereunder shall be in writing and effective only upon receipt and if to the Initial Purchasers shall be delivered, mailed or sent to ▇.▇. ▇▇▇▇▇▇ Securities Inc. at ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, (telefax: 212-622-8358), Attention: Syndicate Desk, with a copy to the Legal Department; Deutsche Bank Securities Inc. at ▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention Equity Capital Markets, Fax: ▇▇▇-▇▇▇-▇▇▇▇ with a copy to the General Counsel, Fax: ▇▇▇-▇▇▇-▇▇▇▇.; ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co.

EXHIBIT A-1

OPINION OF OUTSIDE COUNSEL FOR THE COMPANY

The opinion of Pillsbury ▇▇▇▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇▇ LLP, outside counsel for the Company, to be delivered pursuant to Section 5(d) of the Underwriting Agreement, shall be to the effect that:

1. The Company has been duly incorporated, is validly existing as a corporation in good standing under the Delaware General Corporation Law, has the corporate power and authority to own its property and to conduct its business as described in the Time of Sale Memorandum and the Final Offering Memorandum and is duly qualified to transact business and is in good standing in the jurisdictions set forth on Schedule A hereto.

2. The authorized capital stock of the Company conforms as to legal matters to the description thereof in the Time of Sale Memorandum and the Final Offering Memorandum.

3. The Notes are in the form contemplated by the Indenture and have been duly authorized by the Company and, when issued and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by you in accordance with the terms of the Purchase Agreement, will be valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to and limited by the effect of applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and other similar laws affecting creditors’ rights generally, general equitable principles (whether considered in a proceeding in equity or at law), and concepts of materiality, reasonableness, good faith and fair dealing, and will be entitled to the benefits of the Indenture and the Registration Rights Agreement.

4. The Purchase Agreement has been duly authorized, executed and delivered by the Company.

5. The Underlying Securities issuable upon conversion of the Notes have been duly authorized and reserved upon such conversion and, if issued on the date hereof in accordance with the terms of the Notes, upon such conversion would be validly issued, fully paid and non-assessable and the issuance of the Underlying Securities will not be subject to any preemptive or similar rights.

6. Each of the Indenture and the Registration Rights Agreement has been duly authorized, executed and delivered by the Company, and is a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, subject to and limited by the effect of applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and other similar laws affecting creditors’ rights generally, general equitable principles (whether considered in a proceeding in equity or at law), and concepts of materiality, reasonableness, good faith and fair dealing, and except as rights to indemnification and contribution under the Registration Rights Agreement may be limited by applicable law.

7. The execution and delivery by the Company of and the performance by the Company of its obligations under, the Purchase Agreement, the Indenture, the Registration Rights Agreement and the Securities will not violate or conflict with, result in a breach of, or constitute a default under, (a) any federal, New York or California statute, rule or regulation or provision of the Delaware General Corporation Law, (b) the certificate of incorporation or bylaws of the Company or any Reviewed Agreement, or (c) to our knowledge, any judgment, order or decree of any governmental body, agency or court having jurisdiction over the Company or any subsidiary. “Reviewed Agreement” means the instruments or agreements to which the Company or its subsidiaries is a party or by which the Company or its subsidiaries is bound or to which any of the properties of the Company or its subsidiaries is subject, and which instrument or agreement is included as an exhibit filed pursuant to Item 601(b)(4) and Item 601(b)(10) of Regulation S-K to the Annual Report.

8. To our knowledge, subject to the same assumptions set forth in paragraph 11 below insofar as such paragraph relates to the Securities Act of 1933 (the “Securities Act”) and the Trust Indenture Act of 1939 (the “TIA”), no consent, approval, authorization or order of, or qualification with, any governmental body or agency is required for the performance by the Company of its obligations under the Purchase Agreement, the Indenture, the Registration Rights Agreement and the Securities except such as may be required by (a) the securities or Blue Sky laws of the various states in connection with the offer and sale of the Securities by you and (b) the Securities Act or the TIA and the rules and regulations thereunder and the securities or Blue Sky laws of the various states with respect to the Registration Rights Agreement and the transactions contemplated thereunder.

9.

OPINION OF GENERAL COUNSEL OF THE COMPANY

The opinion of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, Esq., Secretary and General Counsel of the Company, to be delivered pursuant to Section 5(d) of the Purchase Agreement, shall be to the effect that:

(i) The Company has been duly incorporated, is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, has the corporate power and authority to own its property and to conduct its business as described in the Time of Sale Memorandum and Final Offering Memorandum and is duly qualified to transact business and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or be in good standing would not have a material adverse effect on the Company and its subsidiaries, taken as a whole.

(ii) The Notes are in the form contemplated by the Indenture and have been duly authorized by the Company and, when executed and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Initial Purchasers in accordance with the terms of the Purchase Agreement, will be valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to and limited by the effect of applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and other similar laws affecting creditors’ rights generally, general equitable principles (whether considered in a proceeding in equity or at law), and concepts of materiality, reasonableness, good faith and fair dealing, and will be entitled to the benefits of the Indenture and the Registration Rights Agreement.

(iii) The Purchase Agreement has been duly authorized, executed and delivered by the Company.

(iv) Each of the Indenture and the Registration Rights Agreement has been duly authorized, executed and delivered by the Company, and is a valid and binding agreement of the Company, enforceable in accordance with its terms, subject to and limited by the effect of applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and other similar laws affecting creditors’ rights generally, general equitable principles (whether considered in a proceeding in equity or at law), and concepts of materiality, reasonableness, good faith and fair dealing, and except as rights to indemnification and contribution under the Registration Rights Agreement may be limited by applicable law.

(v) The execution and delivery by the Company of, and the performance by the Company of its obligations under, the Purchase Agreement, the Indenture, the Registration Rights Agreement and the Securities will not violate or conflict with, result in a breach of, or constitute a default under, (a) any provision of federal or Utah statute,

rule or regulation or the Delaware General Corporation Law that, in my experience, is normally applicable to transactions contemplated by such documents, (b) the certificate of incorporation or bylaws of the Company or (c) to my knowledge, any agreement or other instrument binding upon the Company that is material to the Company and its subsidiaries, taken as a whole, any judgment, order or decree of any governmental body, agency or court having jurisdiction over the Company or any subsidiary, and no consent, approval, authorization or order of, or qualification with, any governmental body or agency is required for the performance by the Company of its obligations under the Purchase Agreement, the Indenture, the Registration Rights Agreements and the Securities, except such as may be required by the securities or Blue Sky laws of the various states in connection with the offer and sale of the Securities by the Initial Purchasers.

(vi) To my knowledge, after due inquiry, I do not know of any legal or governmental proceedings pending or threatened to which the Company or any of its subsidiaries is a party or to which any of the properties of the Company or any of its subsidiaries is subject other than proceedings fairly summarized in all material respects in the Time of Sale Memorandum and the Final Offering Memorandum and proceedings which I believe are not likely to have a material adverse effect on the Company and its subsidiaries, taken as a whole, or on the power or ability of the Company to perform its obligations under the Purchase Agreement, the Indenture and the Registration Rights Agreement or to consummate the transactions contemplated by the Final Offering Memorandum.

(vii) The statements included in “Item 3 Legal Proceedings” of the Company’s annual report on Form 10-K for the year ended September 30, 2006, insofar as such statements purport to constitute summaries of the legal matters referred to therein, are accurate in all material respects.

(viii) To my knowledge (after due inquiry), none of the Company nor its subsidiaries is in default in the performance or observance of any material obligation, agreement, covenant or condition contained in any contract, indenture, loan agreement, note, lease or other agreement or instrument that is described or referred to in the Time of Sale Memorandum or the Final Offering Memorandum.

(ix) (A) each document filed pursuant to the Exchange Act and incorporated by reference in the Time of Sale Memorandum and the Final Offering Memorandum (except for the financial statements and financial schedules and other financial and statistical data included or incorporated by reference therein or omitted therefrom, as to which I need not express any opinion or belief) appeared on its face to be appropriately responsive, in all material respects, to the requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder and (B) no facts have come to my attention that cause me to believe that (1) the Time of Sale Memorandum (except for the financial statements and financial schedules and other financial and statistical data included or incorporated by reference therein or omitted therefrom, as to which I need not express any belief) at the Applicable Time contained any untrue statement of a material fact or omitted to state a material fact required to be stated

therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or (2) the Final Offering Memorandum (except for the financial statements and financial schedules and other financial data included or incorporated by reference therein or omitted therefrom, as to which, I need not express any belief) as of its date or as of the date hereof contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Dear Sirs and Mesdames:

The undersigned understands that ▇.▇. ▇▇▇▇▇▇ Securities Inc. (“▇.▇. ▇▇▇▇▇▇”), Deutsche Bank Securities Inc. (“Deutsche Bank”) and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated (“▇▇▇▇▇▇ ▇▇▇▇▇▇▇”, together with ▇.▇. ▇▇▇▇▇▇ and Deutsche Bank, the “Representatives”)on behalf of the Initial Purchasers (as hereinafter defined), proposes to enter into a Purchase Agreement (the “Purchase Agreement”) with Headwaters Incorporated, a Delaware corporation (the “Company”), providing for the offering (the “Offering”) by the several Initial Purchasers (the “Initial Purchasers”), of $135,000,000 principal amount of Convertible Senior Subordinated Notes Due 2014 of the Company (the “Securities”). The Securities will be convertible into shares of common stock, par value $0.001 per share, of the Company (the “Common Stock”).

To induce the Initial Purchasers that may participate in the Offering to continue their efforts in connection with the Offering, the undersigned hereby agrees that, without the prior written consent of the Representatives on behalf of the Initial Purchasers, it will not, during the period commencing on the date of the final offering memorandum relating to the Offering (the “Final Memorandum”) and ending 90 days after the date of the Final Memorandum, (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) the sale of any Securities to the Initial Purchasers pursuant to the Purchase Agreement, (b) transactions relating to shares of Common Stock or other securities acquired in open market transactions after the completion of the Offering, (c) transfers of shares of Common Stock or securities convertible into Common Stock by the undersigned as a bona fide gift or gifts or (d) transfers of shares of Common Stock or securities convertible into Common Stock by the undersigned to any trust for the benefit of the undersigned or the undersigned’s immediate family; provided that in the case of any transfer

pursuant to clause (c) or (d), (i) each transferee or trustee of the trust shall execute and deliver to the Representatives a duplicate form of this Lock-up Agreement and (ii) no filing by any party (transferor, transferee or trustee) under Section 16(a) of the Securities Exchange Act of 1934, as amended, shall be required or shall be made voluntarily in connection with such transfer (other than a filing on a Form 5 made after the expiration of the 90-day period referred to above). In addition, the undersigned agrees that, without the prior written consent of the Representatives, on behalf of the Initial Purchasers, it will not, during the period commencing on the date of the Final Memorandum and ending 90 days after the date of the Final Memorandum, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s share of Common Stock except in compliance with the foregoing restrictions.

The undersigned understands that the Company and the Initial Purchasers are relying upon this Lock-Up Agreement in proceeding toward consummation of the Offering. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to a Purchase Agreement, the terms of which are subject to negotiation between the Company and the Initial Purchasers.

It is understood that, if the Company notifies you that it does not intend to proceed with the Offering, if the Purchase Agreement does not become effective, or if the Purchase Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Securities, the undersigned will be released from his or its obligations under this Lock-Up Agreement. This Lock-Up Agreement shall lapse and become null and void if the Offering shall not have occurred on or before April 15, 2007.
