(g) The Selling Stockholder shall have requested and caused Xxxxxx & Xxxxxx L.L.P., counsel for the Selling Stockholder, to have furnished to the Representatives its opinion dated the Closing Date and addressed to the Representatives, to the effect that:

(i) this Agreement has been duly authorized, executed and delivered by the Selling Stockholder;

(ii) each of the Reorganization Agreements to which the Selling Stockholder is a party has been duly authorized, executed and delivered by the Selling Stockholder and constitute valid and binding obligations of the Selling Stockholder, enforceable against the Selling Stockholder in accordance with their respective terms, except as may be limited by (1) bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or similar laws affecting the enforcement of creditors' rights generally, and (2) general principles of equity and the discretion of the court before which any proceeding therefor may be brought (whether arising under a proceeding at law or in equity);

(iii) upon consummations of the Reorganization Transactions, the Selling Stockholder will be the record owner of the Securities being sold by it hereunder and has full legal power to

sell, transfer and deliver in the manner provided in this Agreement the Securities being sold by the Selling Stockholder hereunder;

(iv) upon the payment of the purchase price for the Securities to be purchased by the Underwriters from the Selling Stockholder pursuant to this Agreement and the indication by book entry by The Depository Trust Company ("DTC") that such Securities have been credited to the securities accounts of the Underwriters, (1) the Underwriters will acquire a valid security entitlement (within the meaning of Section 8-501 of the UCC (as in effect in the State of New York on the Closing Date) in respect of such Offered Securities, and (2) an action based on an adverse claim to such Securities (whether framed in conversion, replevin, constructive trust, equitable lien, or other theory) may not be asserted against the Underwriters (provided that, in rendering the opinions expressed in this paragraph (iii), such counsel may assume, without any independent inquiry or investigation, that (A) none of the Underwriters, their agents, counsel or other representatives, DTC and Cede & Co. has notice of any adverse claim to the Securities or any security entitlement therein; (B) DTC is a clearing corporation (as defined in UCC Section 8-102(a)(5)); (C) Cede & Co. is acting as DTC's nominee and is not a securities intermediary; (D) each customer account maintained by each Underwriter is the subject of an agreement between DTC and such Underwriter providing, among other things, that such agreement is governed by the law of the State of New York and that the State of New York is DTC's "securities intermediary's jurisdiction" for purposes of Article 8 of the UCC; and (E) no rule adopted by DTC governing the rights and obligations of DTC and the Underwriters conflicts with the provisions of Part 1 or Part 5 of Article 8 of the UCC and is effective pursuant to UCC Section 8-111 as to the matters in this paragraph or the opinions of such counsel expressed in this paragraph (iii), and such counsel may also state that its opinion in this paragraph (iii) regarding adverse claims that may not be asserted against the Underwriters is given within the meaning of Section 8-502 of the UCC);

(v) no consent, approval, authorization or order of any court or Governmental Authority is required for the consummation by the Selling Stockholder of the transactions contemplated herein or any of the Reorganization Transactions, except such as may have been obtained under the Act, state or foreign securities laws or the rules and regulations of the NASD and such as may be required under the blue sky laws of any jurisdiction in connection with the purchase and distribution of the Securities by the Underwriters in the manner contemplated in this Agreement and in the Prospectus and such other approvals (specified in such opinion) as have been obtained; and

(vi) the execution and delivery by the Selling Stockholder of this Agreement and the Reorganization Agreements and the consummation by the Selling Stockholder of the transactions contemplated hereby, including the sale of the Securities to be sold by the Selling Stockholder and the Reorganization Transactions, will not (i) conflict with the certificate of formation or limited liability company agreement of the Selling Stockholder, (ii) constitute a violation of, or a breach or default under, the terms of any Applicable Selling Stockholder Contract, or (iii) violate or conflict with, or result in any contravention of, any Applicable Law (for purposes of such opinion, "Applicable Selling Stockholder Contracts" shall include the Reorganization Agreements and any other agreements known to such counsel after reasonable inquiry that are material to such Selling Stockholder and/or the transactions contemplated by this Agreement.

In rendering such opinion, such counsel may rely (A) as to matters involving the application of laws of any jurisdiction other than the State of Delaware or the Federal laws of the United States, to the extent they deem proper and specified in such opinion, upon the opinion of other counsel of good standing whom they believe to be reliable and who are satisfactory to counsel for

the Underwriters, and (B) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Selling Stockholder and public officials.

(h) The Representatives shall have received from Skadden, Arps, Slate, Xxxxxxx & Xxxx LLP, counsel for the Underwriters, such opinion or opinions, dated the Closing Date and addressed to the Representatives, with respect to the issuance and sale of the Securities, the Registration Statement, the Prospectus (together with any supplement thereto) and other related matters as the Representatives may reasonably require, and the Company and the Selling Stockholder shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters.

(i) The Company shall have furnished to the Representatives a certificate of the Company, signed by the Chairman of the Board or the President and the principal financial or accounting officer of the Company, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Registration Statement, the Prospectus, any supplements to the Prospectus and this Agreement and that:

(i) the representations and warranties of the Company in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date;

(ii) no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or, to the Company's knowledge, threatened; and

(iii) since the date of the most recent financial statements included in the Prospectus (exclusive of any supplement thereto), there has been no material adverse effect on the condition (financial or otherwise), prospects, earnings, business or properties of the Company, Huntsman Holdings and each subsidiary, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in the Prospectus (exclusive of any supplement thereto).

(j) The Selling Stockholder shall have furnished to the Representatives a certificate, signed by a trustee of the Selling Stockholder, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Registration Statement, the Prospectus, any supplement to the Prospectus and this Agreement and that the representations and warranties of the Selling Stockholder in this Agreement are true and correct in all material respects on and as of the Closing Date to the same effect as if made on the Closing Date.

(k) The Company shall have requested and caused Deloitte & Touche LLP to have furnished to the Representatives, at the Execution Time and at the Closing Date, letters, dated respectively as of the Execution Time and as of the Closing Date, in form and substance satisfactory to the Representatives, to the effect set forth in Annex B.

(l) J. Xxxx Xxxxxx, executive vice president and chief financial officer of the Company and L. Xxxxxxx Xxxxx, vice president and controller of the Company shall have furnished to the Representatives, certificates (the "CFO/Controller Certificates"), dated respectively as of the Execution Time and as of the Closing Date, in form and substance satisfactory to the Representatives to the effect set forth in Annex C.

(m) Subsequent to the Execution Time or, if earlier, the dates as of which information is given in the Registration Statement (exclusive of any amendment thereof) and the Prospectus (exclusive of any supplement thereto), there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph (k) of this Section 6 or (ii) any change, or

any development involving a prospective change, in or affecting the condition (financial or otherwise), earnings, business or properties of the Company, Huntsman Holdings and any subsidiary taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in the Prospectus (exclusive of any supplement thereto) the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Registration Statement (exclusive of any amendment thereof) and the Prospectus (exclusive of any supplement thereto).

(n) Prior to the Closing Date, the Company and the Selling Stockholder shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request.

(o) Subsequent to the Execution Time, there shall not have been any decrease in the rating of any of the Company's debt securities by any "nationally recognized statistical rating organization" (as defined for purposes of Rule 436(g) under the Act) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change.

(p) The Securities shall have been listed and admitted and authorized for trading on the New York Stock Exchange, and satisfactory evidence of such actions shall have been provided to the Representatives.

(q) At the Execution Time, the Company shall have furnished to the Representatives a letter substantially in the form of Exhibit A hereto from each person listed on Schedule V hereto addressed to the Representatives.

If any of the conditions specified in this Section 6 shall not have been fulfilled when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Representatives and counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder may be canceled at, or at any time prior to, the Closing Date by the Representatives. Notice of such cancellation shall be given to the Company and the Selling Stockholder in writing or by telephone or facsimile confirmed in writing.

The documents required to be delivered by this Section 6 shall be delivered at the office of Skadden, Arps, Slate, Xxxxxxx & Xxxx LLP, counsel for the Underwriters, at Xxxx Xxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx, 00000, on the Closing Date.

7. Reimbursement of Underwriters' Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Company or the Selling Stockholder to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters severally through Citigroup Global Markets Inc. on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities. If the Company is required to make any payments to the Underwriters under this Section 7 because of the Selling Stockholder's refusal, inability or failure to satisfy any condition to the obligations of the Underwriters set forth in Section 6, the Selling Stockholder shall reimburse the Company on demand for all amounts so paid.

8. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any

and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law 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 a material fact contained in the registration statement for the registration of the Securities as originally filed or in any amendment thereof, or in any Preliminary Prospectus or the Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) The Selling Stockholder agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act to the same extent as the indemnity to each Underwriter contained in subsection (a) above, but only with respect to written information relating to the Selling Stockholder furnished to the Company by or on behalf of the Selling Stockholder specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which the Selling Stockholder may otherwise have.

(c) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement, and each person who controls the Company within the meaning of either the Act or the Exchange Act and the Selling Stockholder, and each person, if any, who controls the Selling Stockholder within the meaning of the Act or the Exchange Act to the same extent as the indemnity to each Underwriter contained in subsection (a) above, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Company and the Selling Stockholder acknowledge that the statements set forth in the last paragraph of the cover page regarding delivery of the Securities and, under the heading "Underwriting", (i) the list of Underwriters and their respective participation in the sale of the Securities, (ii) the third paragraph, (iii) the eighth paragraph, (iv) the eleventh paragraph and (v) the twelfth paragraph in any Preliminary Prospectus and the Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Prospectus or the Prospectus.

(d) In connection with the offer and sale of the Reserved Securities, the Company agrees, to indemnify and hold harmless the Underwriters, their Affiliates and selling agents and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act, from and against any and all loss, liability, claim, damage and expense (including, without limitation, any legal or other expenses reasonably incurred in connection with defending, investigating or settling any such action or claim), as incurred, (i) arising out of the violation of any applicable laws or regulations of any jurisdiction where Reserved Securities have been offered; (ii) arising out of any untrue statement or alleged untrue statement of a material fact contained in any prospectus wrapper or other material prepared by or with the consent of the Company for distribution to Invitees in connection with the offer and sale of the Reserved Securities or caused by any omission

or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, when considered in conjunction with any Preliminary Prospectus or the Prospectus not misleading; (iii) caused by the failure of any Invitee to pay for and accept delivery of Reserved Securities which have been orally confirmed for purchase by any Invitee by the end of the first business day after the date of the Agreement; or (iv) related to, arising out of or in connection with, the offer and sale of the Reserved Securities.

(e) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a), (b) or (c) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a), (b), (c) or (d) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding 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. Notwithstanding anything contained herein to the contrary, if indemnity may be sought pursuant to Section 8(c) hereof in respect of such action or proceeding, then in addition to such separate firm for the indemnified parties, the indemnifying party shall be liable for the reasonable fees and expenses of not more than one separate firm (in addition to any local counsel) for Xxxxxxx Xxxxx, the directors, officers, employees and agents of Xxxxxxx Xxxxx, and all persons, if any, who control Xxxxxxx Xxxxx within the meaning of either the Act or the Exchange Act for the defense of any losses, claims, damages and liabilities arising in connection with the Reserved Securities which are designated by the Company for sale to Invitees.

(f) In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company, and the Selling Stockholder and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively "Losses") to which the Company and the Selling Stockholder and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholder on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Selling Stockholder and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Selling Stockholder on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company and the Selling Stockholder, shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by the Company on one hand and the Selling Stockholder on the other, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company and the Selling Stockholder, on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Selling Stockholder and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (f).

(g) The liability of the Selling Stockholder under the Selling Stockholder representations and warranties contained in Section 1 hereof and under the indemnity and contribution agreements contained in this Section 8 and otherwise with respect to this Agreement shall be limited to an amount equal to the initial public offering price of the Securities sold by the Selling Stockholder to the Underwriters. The Company and the Selling Stockholder may agree, as among themselves and without limiting the rights of the Underwriters under this Agreement, as to the respective amounts of such liability for which they each shall be responsible.

9. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate amount of Securities set forth opposite the names of all the remaining

Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Securities set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter, the Selling Stockholder or the Company. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement and the Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company, the Selling Stockholder and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in the Company's Common Stock shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Prospectus (exclusive of any supplement thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers, of the Selling Stockholder and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, the Selling Stockholder or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representatives, will be mailed, delivered or telefaxed to Citigroup Global Markets, Inc.; or, if sent to the Company, will be mailed, delivered or telefaxed to (000) 000-0000 and confirmed to it at 000 Xxxxxxxx Xxx, Xxxx Xxxx Xxxx, Xxxx 00000, attention of the Legal Department; or if sent to the Selling Stockholder, will be mailed, delivered or telefaxed and confirmed to it at the address set forth in Schedule VI hereto.

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 8 hereof, and no other person will have any right or obligation hereunder.

14. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

15. Counterparts. This Agreement may be signed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same agreement.
