Ladies and Gentlemen:

1. Offering. The stockholder named in Schedule II hereto (the “Selling Stockholder”) of Westlake Chemical Corporation, a Delaware corporation (the “Company”), proposes to sell to the several Underwriters listed in Schedule I hereto (the “Underwriters”), for whom you are acting as representative (the “Representatives”), an aggregate of 5,500,000 shares (the “Underwritten Shares”) and, at the option of the Underwriters, up to an additional 825,000 shares (the “Option Shares”) of common stock, par value $0.01 per share (the “Stock”), of the Company. The Underwritten Shares and the Option Shares are herein referred to as the “Shares”.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (No. 333-124581), including a form of prospectus, for the registration of the offer and sale of certain securities, including the Shares, under the Securities Act of 1933, as amended (the “1933 Act”), from time to time in accordance with Rule 415 of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”). Such registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the 1933 Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, any preliminary prospectus (including any preliminary prospectus supplement) relating to the Shares filed with the Commission pursuant to Rule 424(b) under the 1933 Act is hereinafter called a “Preliminary Prospectus”, and the term “Prospectus” means the prospectus in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Shares. If the Company has filed an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. Any reference in this Agreement to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or the Prospectus, as the case may be and any reference to


“amend”, “amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “1934 Act”) that are deemed to be incorporated by reference therein. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

At or prior to the time when sales of the Shares were first made (the “Applicable Time”), the Company had prepared the Preliminary Prospectus dated April 20, 2006 (together with the pricing information contained on Schedule IV hereto, the “Pricing Disclosure Package”). For purposes of this Agreement, all references to the Registration Statement, any Preliminary Prospectus or the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to be identical to the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”).

The Company will promptly advise the Underwriters (i) at any time when a prospectus relating to the Shares is required to be delivered under the 1933 Act, when any post-effective amendment to the Registration Statement shall have been filed or become effective, (ii) of any request by the Commission for any post-effective amendment of the Registration Statement or supplement to the Prospectus or any Issuer Free Writing Prospectus or for any additional information, (iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or preventing or suspending the use of the Prospectus or any Issuer Free Writing Prospectus or the institution or threatening by direct communication with the Company of any proceeding for that purpose, and (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Shares for sale in any jurisdiction or the initiation or threatening by direct communication with the Company of any proceeding for such purpose.

The Company will use its reasonable best efforts to prevent the issuance of any stop order suspending the effectiveness of the Registration Statement or preventing or suspending the use of the Prospectus or any Issuer Free Writing Prospectus and, if issued, to obtain as soon as possible the withdrawal thereof.

(b) If at any time when a prospectus relating to the Shares is required to be delivered under the 1933 Act (the “Prospectus Delivery Period”), any event occurs as a result of which the Prospectus or the Pricing Disclosure Package would include any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it shall be necessary to amend the Registration Statement or to supplement the Prospectus or the Pricing Disclosure Package to comply with the 1933 Act or the 1934 Act, or the 1933 Act Regulations or the 1934 Act Regulations, the Company promptly will (i) notify the Underwriters, (ii) prepare and file with the Commission, subject to the first sentence of paragraph (a) of this Section 6, an amendment or supplement which will correct such statement or omission or effect such compliance, and (iii) supply any supplemented Prospectus or any supplemented Pricing Disclosure Package to the Underwriters in such quantities as the Underwriters may reasonably request.

(c) As soon as practicable, but not later than 90 days after the close of the period covered by the earnings statement, the Company will make generally available to its security holders and to the Underwriters an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the 1933 Act and Rule 158 of the 1933 Act Regulations.

(d) The Company will retain in accordance with the 1933 Act Regulations all Issuer Free Writing Prospectuses not required to be filed pursuant to the 1933 Act Regulations; and if at any time during the Prospectus Delivery Period any events shall have occurred as a result of which any Issuer Free Writing Prospectus, as then amended or supplemented, would conflict with the information in the Registration Statement, the Preliminary Prospectus or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements in the Issuer Free Writing Prospectus, in the light of the circumstances under which they were made, not misleading, or, if for any other reason it shall be necessary to amend or supplement any Issuer Free Writing Prospectus, to notify the Underwriters

and, upon their request and to the extent required by applicable law, to file such document and to prepare and furnish without charge to each Underwriter as many copies as the Lead Underwriters may from time to time reasonably request of an amended or supplemented Issuer Free Writing Prospectus that will correct such conflict, statement or omission or effect such compliance.

(e) The Company will use its reasonable best efforts to qualify the Shares for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Lead Underwriters shall reasonably request and will continue such qualifications in effect so long as required for the distribution of the Shares, provided that the Company shall not be required to qualify as a foreign corporation or other entity or to file a general consent to service of process in any jurisdiction.

(f) For a period of 90 days after the date of the initial public offering of the Shares, the Company will not (i) offer, pledge, announce the intention to sell, 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 or otherwise transfer or dispose of, directly or indirectly, any shares of Stock or any securities convertible into or exercisable or exchangeable for Stock or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Stock or such other securities, in cash or otherwise, without the prior written consent of J.P.

extent the documented expenses of the Company are less than the sum of (A) $429,687 and (B) the amount contemplated by the immediately preceding proviso (the “Maximum Reimbursement Amount”), the Underwriters agree to reimburse the Selling Stockholder, on a pro rata basis in accordance with the number of Shares purchased by each Underwriter, for the Selling Stockholder’s documented expenses, if any, related to the offering of Shares contemplated hereby, in an aggregate amount not to exceed the difference between (A) the Maximum Reimbursement Amount and (B) the amount reimbursed to the Company.

(c) Each Underwriter will severally and not jointly indemnify and hold harmless the Company and its directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act and the Selling Stockholder, against any losses, claims, damages or liabilities to which the Company or the Selling Stockholder may become subject, under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, the Preliminary Prospectus, or any Issuer Free Writing Prospectus or in any amendment or supplement thereto, or arise out of or are based upon the omission or the alleged omission to state in the Registration Statement, the Prospectus, or any amendment or supplement thereto, the Preliminary Prospectus or any Issuer Free Writing Prospectus or in any amendment or supplement thereto, a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Underwriter specifically for use therein (the “Underwriter Information”), and will reimburse any legal or other expenses reasonably incurred by the Company and the Selling Stockholder in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the first sentence of the third paragraph of the “Underwriting” section of the final prospectus supplement and the corresponding information in the preliminary prospectus supplement dated April 20, 2006.

(d) Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under subsection (a), (b) or (c) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a), (b) or (c) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a), (b) or (c) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action 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 (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(e) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (c) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (c) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the other from the offering of the Shares or (ii) if the allocation provided by clause

 

-21-


(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 (i) above but also the relative fault of the Company and the Selling Stockholder on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Selling Stockholder bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault 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, the Selling Stockholder or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (e). Notwithstanding the provisions of this subsection (e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter 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 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(f) The obligations of the Company and the Selling Stockholder under this Section shall be in addition to any liability which the Company and the Selling Stockholder may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the 1933 Act; and the obligations of the Underwriters under this Section shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer of the Company who has signed the Registration Statement and to each person, if any, who controls the Company within the meaning of the 1933 Act.

10. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase the Shares hereunder and the aggregate number of Shares that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of Shares that the Underwriters are obligated to purchase on the Closing Date or the Additional Closing Date, as the case may be, the Underwriters may make arrangements satisfactory to the Company and the Selling Stockholder for the purchase of such Shares by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date or the Additional Closing Date, as the case may be, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Shares that such defaulting Underwriters agreed but failed to purchase on the Closing Date or the Additional Closing Date, as the case may be. If any Underwriter or Underwriters so default and the aggregate number of Shares with respect to which such default or defaults occur exceeds 10% of the aggregate number of Shares that the Underwriters are obligated to purchase on the Closing Date or the Additional Closing Date, as the case may be, and arrangements satisfactory to the Underwriters and the Company for the purchase of such Shares by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Selling Stockholder or the Company, except as provided in Section 11. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10. Nothing herein will relieve a defaulting Underwriter from liability for its default.

 

-22-


11. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Selling Stockholder, the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company, the Selling Stockholder or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Shares. If this Agreement is terminated pursuant to Section 10 or if for any reason the purchase of the Shares by the Underwriters is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 6 and the respective obligations of the Company, the Selling Stockholder and the Underwriters pursuant to Section 9 shall remain in effect, and if any Shares have been purchased hereunder, the representations and warranties in Section 2 and all obligations under Section 6 shall also remain in effect. If the purchase of the Shares by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 10 or the occurrence of any event specified in clause (iii), (iv), (vi), (vii) or (viii) of Section 8(d), the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Shares.

12. Free Writing Prospectus. Each Underwriter severally covenants with the Company that it has not made and will not make any offer relating to the Shares that would constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission without the consent of the Company, not to be unreasonably withheld, other than any such offer included in an Issuer Free Writing Prospectus. The Company covenants with the Underwriters that it has not made and will not make any offer relating to the Shares that would constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission without the consent of the Lead Underwriters, not to be unreasonably withheld, other than any such offer included in an Issuer Free Writing Prospectus.

13. Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or faxed and confirmed to the Underwriters, c/o J.P. Morgan Securities Inc., 277 Park Avenue, New York, New York 10172 (fax: (212)  ###-###-####); Attention: Henry K. Wilson, or, if sent to the Company, will be mailed, delivered or faxed and confirmed to it at 2801 Post Oak Boulevard, Suite 600, Houston, Texas 77056, Attention: General Counsel (fax (713)  ###-###-####) or, if sent to the Selling Stockholder, will be mailed, delivered or faxed and confirmed to TTWFGP LLC at 2801 Post Oak Boulevard, Houston, Texas 77056 (fax (713 ###-###-####)); provided, however, that any notice to an Underwriter pursuant to Section 9 will be mailed, delivered or faxed and confirmed to such Underwriter.

14. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 10, and no other person will have any right or obligation hereunder.

15. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

16. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to principles of conflicts of laws.
