Huntsman Corporation (the “Corporation”) shall maintain a registered office in Delaware and may maintain such other offices and keep its books, documents and records at such places within or without Delaware as may, from time to time, be designated by the board of directors of the Corporation (collectively, the “Board” and each director, a “Director”).

ARTICLE II
STOCKHOLDERS

Section 2.1.                                 Annual Meeting.  The annual meeting of the stockholders of the Corporation shall be held on such date and at such time as may be fixed by resolution of the Board.

Section 2.2.                                 Special Meeting.  Except as otherwise required by law and subject to the rights of the holders of any class or series of stock having a preference over the Common Stock, as defined in the Amended and Restated Certificate of Incorporation of the Corporation (the “Certificate of Incorporation”), as to dividends or upon liquidation, special meetings of the stockholders of the Corporation for any purpose or purposes may be called only by:

(a)                                 the Board pursuant to a resolution stating the purpose or purposes thereof approved by a majority of the total number of authorized Directors, whether or not there exists any vacancy in previously authorized directorships (the “Whole Board”), or

(b)                                 the Chairman of the Board.

No business other than that stated in the notice shall be transacted at any special meeting.

Section 2.3.                                 Place of Meeting.  The Board or the Chairman of the Board, as the case may be, may designate the place of meeting for any annual meeting or for any special meeting of the stockholders. If no designation is so made, the place of meeting shall be the principal office of the Corporation.

Section 2.4.                                 Fixing Record Dates.  In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, or entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board, and which record date: (1) in the case of determination of stockholders entitled to vote at any meeting of stockholders or adjournment thereof, shall, unless otherwise required by law, not be more than sixty (60) nor less than ten (10) days before the date of such meeting; and (2) in the case of any other action, shall not be more than sixty (60) days prior to such other action. If no

1

record date is fixed: (1) the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held; and (2) the record date for determining stockholders for any other purpose shall be at the close of business on the day on which the Board adopts the resolution relating thereto. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board may fix a new record date for the adjourned meeting.

Section 2.5.                                 Notice of Meeting.  Notice, stating the place, day and hour of the meeting and the means of remote communication, if any, by which stockholders and proxyholders may be deemed present in person and vote at such meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called, shall be given not less than ten calendar days nor more than 60 calendar days before the date of the meeting to each stockholder of record entitled to vote at such meeting, except as otherwise provided herein or required by law or the Certificate of Incorporation. If mailed, such notice shall be deemed to be delivered when deposited in the United States mail with postage thereon prepaid, addressed to the stockholder at such person’s address as it appears on the stock transfer books of the Corporation. Without limiting the manner by which notice otherwise may be given to stockholders, any notice to stockholders may be given by electronic transmission in the manner provided by Section 232 of the Delaware General Corporation Law (the “DGCL”). Meetings may be held without notice if all stockholders entitled to vote are present (without being present for the purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened), or if notice is waived by those not present in accordance with Section 7.4 of these Bylaws. The Board may cancel, reschedule or postpone any previously scheduled annual or special meeting.

Section 2.6.                                 Quorum and Adjournment; Voting.  Except as otherwise provided by law or by the Certificate of Incorporation, the holders of a majority of the voting power of all outstanding shares of the Corporation entitled to vote in the election of Directors (the “Voting Stock”), represented in person or by proxy, shall constitute a quorum at a meeting of stockholders, except that when specified business is to be voted on by a class or series of stock voting separately as a class, the holders of a majority of the voting power of all outstanding shares of such class or series represented in person or by proxy shall constitute a quorum of such class or series for the transaction of such business. The chairman of the meeting, as determined by Article IV of these Bylaws, may adjourn the meeting from time to time, whether or not there is such a quorum. No notice of the time and place of adjourned meetings need be given if the time and place, if any, thereof, and the means of remote communication, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such adjourned meeting are announced at the meeting at which adjournment is taken; provided, however, that if the date of any adjourned meeting is more than 30 days after the date for which notice was originally given, or if a new record date is fixed for the adjourned meeting, notice of the place, if any, date and time of the adjourned meeting and the means of remote communication, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such adjourned meeting, shall be given in conformity herewith. At any adjourned meeting, any business may be transacted that might have been transacted at the original meeting. The stockholders present at a duly called meeting at which a quorum is present

2

may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum.

Section 2.7.                                 Proxies.  At all meetings of stockholders, a stockholder may vote by proxy executed in writing (or in such other manner permitted by the DGCL) by the stockholder or by such person’s duly authorized attorney-in-fact.

Section 2.8.                                 Notice of Stockholder Business and Nominations.

person or persons (including their names) in connection with the proposal of such business by such stockholder;

(C)                               set forth, as to each person, if any, whom the stockholder proposes to nominate for election or reelection to the Board (1) all information relating to such person that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for election of Directors in a contested election pursuant to Section 14 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules and regulations promulgated thereunder (including such person’s written consent to being named in the proxy statement as a nominee and to serving as a Director if elected) and (2) a description of all direct and indirect compensation and other material monetary agreements, arrangements and understandings during the past three years, and any other material relationships, between or among such stockholder and beneficial owner, if any, and their respective affiliates and associates, or others acting in concert therewith, on the one hand, and each proposed nominee, and his or her respective affiliates and associates, or others acting in concert therewith, on the other hand, including, without limitation all biographical and related party transaction and other information that would be required to be disclosed pursuant to the federal and state securities laws if the stockholder making the nomination and any beneficial owner on whose behalf the nomination is made, if any, or any affiliate or associate thereof or person acting in concert therewith, were the “registrant” for purposes of such rule and the nominee were a director or executive officer of such registrant; and

(D)                               with respect to each nominee for election or reelection to the Board, include a completed and signed questionnaire, representation and agreement required by Section 2.8(d) below.

(iii)                               Notwithstanding anything in the second sentence of paragraph (a)(ii) of this Bylaw to the contrary, in the event that the number of Directors to be elected to the Board is increased and there is no public announcement by the Corporation naming all of the nominees for Director or specifying the size of the increased Board at least 100 calendar days prior to the first anniversary of the preceding year’s annual meeting, a stockholder’s notice required by this Bylaw shall be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary at the principal executive offices of the Corporation not later than the close of business on the 10th calendar day following the day on which such public announcement is first made by the Corporation.

In the event the Corporation calls a special meeting of stockholders for the purpose of electing one or more Directors to the Board, any such stockholder may nominate a person or persons (as the case may be) for election to such position(s) as specified in the Corporation’s notice of meeting pursuant to clause (ii) if the stockholder’s notice required by paragraph (a)(ii) of this Bylaw with respect to any nomination (including the completed and signed questionnaire, representation and agreement required by Section 2.8(d) below) shall be delivered to the Secretary at the principal executive offices of the Corporation not earlier than the close of business on the 120th calendar day prior to such special meeting, nor later than the close of business on the later of the 90th calendar day prior to such special meeting or the 10th calendar day following the day on which public announcement is first made of the date of the special meeting and of the nominees proposed by the Board to be elected at such meeting.

Except as otherwise provided by law, the chairman of the meeting shall have the power and duty (a) to determine whether a nomination or any business proposed to be brought before the meeting was made or proposed, as the case may be, in accordance with the procedures set forth in this Bylaw (including whether the stockholder or beneficial owner, if any, on whose behalf the nomination or proposal is made solicited (or is part of a group which solicited) or did not so solicit, as the case may be, proxies in support of such stockholder’s nominee or proposal in compliance with such stockholder’s representation as required by clause (a)(ii)(A)(3) of this Section 2.8) and (b) if any proposed nomination or business was not made or proposed in compliance with this Bylaw, to declare that such nomination shall be disregarded or that such proposed business shall not be transacted.

Nothing in this Bylaw shall be deemed to affect any rights (A) of stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act or any other applicable federal or state securities law with respect to that stockholder’s request to include proposals in the Corporation’s proxy statement, or (B) of the holders of any series of Preferred Stock to elect Directors under an applicable Preferred Stock Designation (as defined in the Certificate of Incorporation).

The Board may from time to time elect such other officers (including one or more Vice Presidents, Controllers, Assistant Secretaries and Assistant Treasurers) as may be necessary or desirable for the conduct of the business of the Corporation. Such other officers and agents shall have such duties and shall hold their offices for such terms as shall be provided in these Bylaws or as may be prescribed by the Board, as the case may be. Any number of offices may be held by the same person.

Unless the Board has elected a vice-chairman and such vice-chairman is able to act in the place of the Chairman of the Board, the Chief Executive Officer, if he or she is also a director, shall, in the absence, or because of the inability to act, of the Chairman of the Board, perform all duties of the Chairman of the Board and preside as chairman at all meetings of stockholders and the Board.

ARTICLE V
STOCK CERTIFICATES AND TRANSFERS

Section 5.1.                                 Certificates.  The shares of the Corporation shall be represented by certificates, provided that the Board of Directors may provide by resolution or resolutions that some or all of any or all classes or series of stock shall be uncertificated shares. Any such resolution shall not apply to shares represented by a certificate until such certificate is surrendered to the Corporation. Every holder of stock represented by certificates shall be entitled to have a certificate signed by or in the name of the Corporation by the Chairman or Vice Chairman of the Board of Directors, if any, or the President or a Vice President, and by the Treasurer or an Assistant Treasurer, or the Secretary or an Assistant Secretary, of the Corporation certifying the number of shares owned by such holder in the Corporation. Any of or all the signatures on the certificate may be a facsimile. In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed upon a certificate shall have ceased to be such officer, transfer agent, or registrar before such certificate is issued, it may be issued by the Corporation with the same effect as if such person were such officer, transfer agent, or registrar at the date of issue.

Section 5.2.                                 Lost, Stolen or Destroyed Certificates.  No certificate for shares of stock in the Corporation shall be issued in place of any certificate alleged to have been lost, destroyed or stolen, except on production of such evidence of such loss, destruction or theft and on delivery to the Corporation of a bond of indemnity in such amount, upon such terms and secured by such surety, as the Board or any financial officer may in its or such person’s discretion require.

ARTICLE VI
INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 6.1.                                 Right to Indemnification.  Each person who was or is made a party to or is threatened to be made a party to or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter, a “proceeding”), by reason of the fact that such person, or a person of whom such person is the legal representative, is or was a Director or officer of the Corporation or, while a Director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee, trustee or agent of another corporation or of a partnership, limited liability company, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee, trustee or agent or in any other capacity while serving as a director, officer, employee, trustee or agent, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended against all expense, liability and loss (including, without limitation, attorneys’ fees, judgments, fines, amounts paid or to be paid in settlement and excise taxes or penalties arising under the Employment Retirement Income Security Act of 1974, as in effect from time to time) reasonably incurred or suffered by such person in connection therewith; provided, however, that, except as provided in Section 6.2 hereof, the Corporation shall indemnify any such person seeking indemnification in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by the Board. The right to indemnification conferred in this Section 6.1 shall be a contract right. The Corporation shall prepay the expenses incurred in defending any

14

such proceeding in advance of its final disposition, any advance payments to be paid by the Corporation within 20 calendar days after the receipt by the Corporation of a statement or statements from the claimant requesting such advance or advances from time to time; provided, however, that, if and to the extent the DGCL requires, the payment of such expenses incurred by a Director or officer in such person’s capacity as a Director or officer in advance of the final disposition of a proceeding shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such Director or officer, to repay all amounts so advanced if it shall ultimately be determined that such Director or officer is not entitled to be indemnified under this Section 6.1 or otherwise. The Corporation may, to the extent authorized from time to time by the Board, grant rights to indemnification, and rights to have the Corporation pay the expenses incurred in defending any proceeding in advance of its final disposition, to any employee, trustee or agent of the Corporation to the fullest extent of the provisions of this Article VI with respect to the indemnification and advancement of expenses of Directors and officers of the Corporation and may enter into Indemnity Agreements to such effect.

Section 6.2.                                 Right of Claimant to Bring Suit.  If a claim under Section 6.1 of this Article VI is not paid in full by the Corporation within 60 calendar days after a written claim has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expense of prosecuting such claim. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any is required, has been tendered to the Corporation) that the claimant has not met the standard of conduct which makes it permissible under the DGCL for the Corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including its Board, independent legal counsel or its stockholders) to have made a determination prior to the circumstances that the claimant has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the Corporation (including its Board, independent legal counsel or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

Section 6.3.                                 Non-Exclusivity of Rights.  The right to indemnification and the payment of expenses incurred in defending a proceeding in advance of its final disposition conferred in this Article VI shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, Bylaw, agreement, vote of stockholders or disinterested Directors or otherwise. No repeal or modification of this Article VI shall in any way diminish or adversely affect the rights of any Director, officer, employee, trustee or agent of the Corporation hereunder in respect of any occurrence or matter arising prior to any such repeal or modification.

Section 6.4.                                 Insurance.  The Corporation may maintain insurance, at its expense, to protect itself and any Director, officer, employee, trustee or agent of the Corporation or another corporation, partnership, limited liability company, joint venture, trust or other enterprise against any such expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the DGCL.

15

Section 6.5.           Severability.  If any provision or provisions of this Article VI shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (i) the validity, legality and enforceability of the remaining provisions of this Article VI (including, without limitation, each portion of any paragraph of this Article VI containing any such provision held to be invalid, illegal or unenforceable, that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby; and (ii) to the fullest extent possible, the provisions of this Article VI (including, without limitation, each such portion of any paragraph of this Article VI containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested by the provision or provisions held invalid, illegal or unenforceable.

Section 6.6.           Expenses as a Witness.  To the extent that any Director or officer of the Corporation is by reason of such position, or a position as a director, officer, trustee, employee or agent with another entity at the request of the Corporation, a witness in any action, suit of proceeding, he or she shall be indemnified against all costs and expenses actually and reasonably incurred in connection therewith.

Section 6.7.           Nature of Rights.  The rights conferred upon indemnitees by this Article VI shall continue as to an indemnitee who has ceased to be a Director or officer and shall inure to the benefit of such indemnitee’s heirs, executors and administrators. Any repeal or modification of the foregoing provisions of this Article VI shall not adversely affect any right or protection hereunder of any person in respect of any act or omission occurring prior to the time of such repeal or modification.

ARTICLE VII

MISCELLANEOUS PROVISIONS

Section 7.1.           Fiscal Year.  The fiscal year of the Corporation shall begin and end on such dates as the Board at any time shall determine by resolution.

Section 7.2.           Dividends.  The Board may from time to time declare, and the Corporation may pay, dividends on its outstanding shares in the manner and upon the terms and conditions provided by law and the Certificate of Incorporation.

Section 7.3.           Seal.  The corporate seal, if any, shall have inscribed thereon the words “Corporate Seal,” the year of incorporation and the word “Delaware.”

Section 7.4.           Waiver of Notice.  Whenever any notice is required to be given to any stockholder or Director under the provisions of the DGCL or these Bylaws, a waiver thereof by the person or persons entitled to such notice, whether before or after the time stated therein, shall be deemed equivalent to the giving of such notice. Neither the business to be transacted at, nor the purpose of, any annual or special meeting of the stockholders or the Board or any committee thereof need be specified in any waiver of notice of such meeting.

Section 7.5.           Resignations.  Any Director or any officer, whether elected or appointed, may resign at any time by giving written notice of such resignation to the Chairman of the Board or the Secretary, and such resignation shall be deemed to be effective as of the close of business on the date said notice is received by the Chairman of the Board or the Secretary, or at such later

16

time as is specified therein. No formal action shall be required of the Board or the stockholders to make any such resignation effective.

ARTICLE VIII

CONTRACTS; VOTING SECURITIES OF OTHER ENTITIES

Section 8.1.           Contracts.  Except as otherwise required by law, the Certificate of Incorporation, a Preferred Stock Designation or these Bylaws, any contracts or other instruments may be executed and delivered in the name and on the behalf of the Corporation by such officer or officers of the Corporation as the Board may from time to time direct. Such authority may be general or confined to specific instances as the Board may determine. Unless provided otherwise by resolution of the Board, the Chairman or Vice Chairman of the Board, the Chief Executive Officer, the President or any Executive Vice President, Senior Vice President or Vice President may execute bonds, contracts, deeds, leases and other instruments to be made or executed for or on behalf of the Corporation. Subject to any restrictions imposed by the Board, the Chairman or Vice Chairman of the Board, the Chief Executive Officer, the President or any Executive Vice President, Senior Vice President or Vice President of the Corporation may delegate contractual powers to others under such person’s authority, it being understood, however, that any such delegation of power shall not relieve such officer of responsibility with respect to the exercise of such delegated power.

Section 8.2.           Action with Respect to Securities of Other Entities.  Unless otherwise provided by resolution adopted by the Board, the Chairman or Vice Chairman of the Board, the Chief Executive Officer, the President or any officer authorized by one of them shall have the power to vote and otherwise act, appoint an attorney or attorneys or agent or agents of the Corporation, in the name and on behalf of the Corporation, to cast the votes which the Corporation may be entitled to cast as the holder of stock, other securities or interests in any other entity, any of whose stock or other securities or interests may be held by the Corporation, at meetings of the holders of the stock, other securities or interests, of such other entity, or to consent in writing, in the name of the Corporation as such holder, to any action by such other entity, and may instruct the person or persons so appointed as to the manner of casting such votes or giving such consent, and may execute or cause to be executed in the name and on behalf of the Corporation and under its corporate seal or otherwise, all such written proxies or other instruments as he or she may deem necessary or proper and otherwise exercise any and all rights and powers that the Corporation may possess by reason of its ownership of stock, other securities or interests in such other entity.
