V6C 3E1 December 10, 2004 Dear Acetex Shareholders, Acetex Warrantholders and Acetex Optionholders: The Board of Directors of Acetex Corporation ("Acetex") cordially invites all common shareholders, warrantholders and optionholders of Acetex (collectively, the "Acetex Securityholders") to attend a special meeting (the "Meeting") of Acetex to be held at 10:00 a.m. (Pacific Time) on January 12, 2005 at the Pan Pacific Hotel, 999 Canada Place, Vancouver, British Columbia, Canada. At the Meeting, Acetex Securityholders will be asked to approve an arrangement (the "Arrangement") whereby HNA Acquisition Inc. ("HNA") will acquire all of the issued and outstanding Acetex common shares ("Acetex Shares"), warrants to acquire Acetex Shares ("Acetex Warrants") and options to acquire Acetex Shares ("Acetex Options"). HNA is an indirect wholly-owned subsidiary of Celanese Corporation. HNA will acquire Acetex Shares in exchange for a cash amount (without interest) equal to Cdn $9.00 per Acetex Share. Each issued and outstanding Acetex Warrant will be transferred to and acquired by HNA for a cash amount (without interest) equal to Cdn $9.00 per Acetex Warrant less the exercise price of such warrant. Acetex Optionholders will receive (without interest) the greater of (i) Cdn $9.00 per Acetex Option in cash less the exercise price of such Acetex Option and (ii) one cent. The Board of Directors of Acetex has considered at length the proposed acquisition of Acetex and other strategic alternatives for maximizing securityholder value. THE BOARD OF DIRECTORS HAS UNANIMOUSLY DETERMINED THAT THE ARRANGEMENT IS FAIR TO ACETEX SECURITYHOLDERS AND IS IN THE BEST INTERESTS OF ACETEX AND RECOMMENDS THAT YOU VOTE IN FAVOUR OF THE RESOLUTIONS APPROVING THE ARRANGEMENT. The Acetex Board of Directors came to these determinations based on, among other things, the opinion of Acetex's financial adviser, GMP Securities Ltd. that the consideration to be received under the Arrangement in exchange for the Acetex Shares, Acetex Warrants and Acetex Options was fair, from a financial point of view, to Acetex Securityholders. In addition, Acetex's largest shareholders, Brooke N. Wade and Kenneth E. Vidalin, who collectively beneficially own, or exercise control or direction over, 29.36% of the votes to be cast at the Meeting have agreed to irrevocably support the Arrangement and vote in favour of the resolutions approving the Arrangement. Included with this letter are a notice of special meeting and a management information circular (the "Circular"). The Circular contains a detailed description of the Arrangement. Persons holding Acetex Warrants or Acetex Options are entitled to vote on the Arrangement on the basis of one vote for each Acetex Share they are entitled to receive upon the exercise of their Acetex Warrants or Acetex Options whether such Acetex Warrants or Acetex Options are currently exercisable or not. We encourage you to consider carefully all of the information in the accompanying Circular. If you require assistance, please consult your financial, legal or other professional advisers. Also included with this letter are the applicable forms of proxy printed on blue paper. It is important that you are represented at the Meeting. Whether or not you are able to attend, we urge you to complete the applicable enclosed form of proxy and return it in the envelope provided or by fax to Acetex (c/o Computershare Trust Company of Canada, 100 University Avenue, 9th Floor, Toronto, Ontario M5J 2Y1 (Attention: Proxy Department) or by fax to 1-416-263-9524, 1-866-249-7775 or 1-514-982-7125 (Attention: Proxy Department)), not later than 5:00 p.m. (Toronto time) on January 11, 2005, or if the Meeting is adjourned or postponed, prior to 5:00 p.m. (Toronto time) on the business day preceding the date to which the Meeting is adjourned or postponed.

Such letter of transmittal contains instructions on (i) how to deliver your Acetex Shares in exchange for (without interest) Cdn $9.00 cash payment per Acetex Share; (ii) how to exchange your Acetex Warrant for (without interest) Cdn $9.00 cash payment less the exercise price of such Acetex Warrant; or (iii) how to exchange your Acetex Option for the applicable cash payment described above. You will not receive any cash under the Arrangement unless and until the Arrangement is completed and you have returned the properly completed documents, including the applicable letter of transmittal. If you hold your Acetex Shares through a nominee such as a broker or dealer, you should carefully follow any instructions provided to you by such nominee. Subject to obtaining Court and other regulatory approvals, the approval of Acetex Securityholders, and the satisfaction or waiver of other customary conditions, the Arrangement will become effective upon filing the Articles of Arrangement with the Registrar appointed under the BUSINESS CORPORATIONS ACT (Alberta). At this time, the parties cannot estimate when the necessary regulatory approvals will be obtained and the Arrangement will become effective.

4 SUMMARY THE FOLLOWING IS A SUMMARY OF CERTAIN INFORMATION CONTAINED IN THIS CIRCULAR. THE SUMMARY IS NOT INTENDED TO BE COMPLETE AND IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED INFORMATION CONTAINED ELSEWHERE IN THIS CIRCULAR AND THE ATTACHED APPENDICES. ACETEX SECURITYHOLDERS SHOULD READ THE ENTIRE CIRCULAR, INCLUDING THE APPENDICES. MEETING The Meeting will be held on January 12, 2005 at 10:00 a.m. (Pacific Time) at the Pan Pacific Hotel, 999 Canada Place, Vancouver, British Columbia, Canada. At the Meeting, Acetex Securityholders will be asked to consider and, if thought advisable, pass, the Arrangement Resolutions. THE ARRANGEMENT By approving the Arrangement Resolutions, Acetex Securityholders will approve the acquisition of all the Acetex Securities by HNA. Subject to the completion of the Arrangement, Acetex Securityholders (other than Acetex Securityholders who validly exercise their Dissent Rights or any Holdco in respect of which a valid Holdco Election has been made) will receive, as applicable, from HNA consideration (without interest) as follows: (a) for each Acetex Share $9.00 in cash; (b) for each Acetex Warrant $9.00 in cash less the exercise price of such warrant; and (c) for each Acetex Option the greater of (i) $9.00 in cash less the exercise price of such Acetex Option and (ii) one cent. An Acetex Shareholder who qualifies as a Holdco may elect to have all issued and outstanding shares of the Holdco transferred to HNA in exchange for $9.00 cash per Holdco Share, provided that, among other things, the Holdco enters into a satisfactory Holdco Agreement. For more information, see "ARRANGEMENT MECHANICS - The Holdco Election". After completion of the Arrangement, Acetex will be a wholly-owned Subsidiary of HNA and former Acetex Securityholders will no longer be securityholders of Acetex. See "INFORMATION CONCERNING THE ARRANGEMENT - The Arrangement". ACETEX Acetex with 2003 revenues of U.S. $484 million and approximately 900 employees worldwide has two primary businesses - its Acetyls business and the Specialty Polymers and Films business. The Acetyls business, based in Europe, produces acetic acid, polyvinyl alcohol and vinyl acetate monomer. These chemicals and their derivatives are used in a wide range of applications in the automotive, construction, packaging, pharmaceutical and textile industries. Specialty polymers developed and manufactured by Acetex are used in the manufacture of a variety of plastics products, including packaging and laminating products, auto parts, adhesives and medical products. The Films business focuses on products for the agricultural, horticultural and construction industries. Acetex was incorporated under the ABCA on December 1, 1994 and has its head office at 750 World Trade Centre, 999 Canada Place, Vancouver British Columbia, Canada. HNA HNA is an indirect wholly-owned Subsidiary of Celanese. Celanese, through its Subsidiaries, is an integrated global producer of value-added industrial chemicals. The operations of Celanese and its Subsidiaries are located in North America, Europe and Asia, including substantial joint ventures in China. HNA was incorporated under the CANADA BUSINESS CORPORATIONS ACT on July 25, 1999. The registered office of HNA is located at 1700 Oxford Tower, 10235-101 Street, Edmonton, Alberta T5J3G1. See "INFORMATION ABOUT HNA". 5 HNA does not hold any Acetex Securities as of the date of this Circular. PROCEDURE FOR THE ARRANGEMENT TO BECOME EFFECTIVE PROCEDURAL STEPS The Arrangement is proposed to be carried out pursuant to Section 193 of the ABCA. The following procedural steps must be taken in order for the Arrangement to become effective: (a) the Arrangement must be approved by at least two-thirds of the votes cast in person or by proxy by Acetex Securityholders voting together as a single class at the Meeting; (b) the Court must grant the Final Order approving the Arrangement; (c) all conditions precedent to the Arrangement, as set forth in the Arrangement Agreement, must be satisfied or waived by the appropriate party; and (d) the Final Order and Articles of Arrangement in the form prescribed by the ABCA must be filed with the Registrar. Notwithstanding the foregoing, the Arrangement Resolutions authorize the Board of Directors, without further notice to, or approval of the Acetex Securityholders, subject to the terms of the Arrangement and the Arrangement Agreement (subject to the consent of HNA where required), to amend or terminate the Arrangement Agreement or the Plan of Arrangement or rescind the Arrangement Resolutions at any time prior to the filing of Articles of Arrangement giving effect to the Arrangement. See Appendix A to this Circular for the full text of the Arrangement Resolutions. COURT APPROVAL An arrangement under the ABCA requires approval by the Court pursuant to the Final Order. On December 8, 2004, Acetex obtained the Interim Order providing for the calling and holding of the Meeting and other procedural matters. A copy of the Interim Order is attached as Appendix B to this Circular. If the Meeting is held and the Arrangement Resolutions are approved as required by the Interim Order, Acetex will apply to the Court for the Final Order approving the Arrangement. The hearing in respect of the Final Order is scheduled to take place on or about January 13, 2005 at 1:30 p.m. (Calgary time) at the Court House, 611 - 4th Street S.W., Calgary, Alberta, Canada. Subject to all conditions precedent to the Arrangement as set forth in the Arrangement Agreement being satisfied or waived by the appropriate party, the Arrangement will become effective upon the filing with the Registrar of the Articles of Arrangement. At this time, the parties cannot estimate when the necessary regulatory approvals will be obtained and the Arrangement will become effective. Unless HNA and Acetex agree otherwise, the Arrangement Agreement will be terminated if the Arrangement has not been completed on or before August 31, 2005. See "INFORMATION CONCERNING THE ARRANGEMENT -- Court Approval of the Arrangement and Completion of the Arrangement". REGULATORY APPROVALS The Arrangement is subject to European, United States, Canadian and certain other antitrust Laws. HNA and Acetex are not permitted to complete the Arrangement until the waiting periods under all applicable antitrust Laws have expired or been terminated, approval or deemed approval under the Investment Canada Act has been obtained, and HNA and Acetex have obtained all other regulatory approvals without which the Arrangement would be prohibited. Antitrust filings have been, or will shortly be, made in all necessary jurisdictions. While the parties cannot estimate at this time how long it will take to receive the necessary regulatory approvals, it is expected that not all of the regulatory approvals will be obtained by the date of the Meeting. Unless HNA and Acetex agree otherwise, the Arrangement Agreement will be terminated if the Arrangement has not been completed on or before August 31, 2005. See "INFORMATION CONCERNING THE ARRANGEMENT - Regulatory Matters". 6 RECOMMENDATION OF ACETEX'S BOARD OF DIRECTORS The Board of Directors of Acetex has considered at length the proposed acquisition of Acetex and other strategic alternatives for maximizing shareholder value. THE BOARD OF DIRECTORS HAS UNANIMOUSLY DETERMINED THAT THE ARRANGEMENT IS FAIR TO ACETEX SECURITYHOLDERS AND IS IN THE BEST INTERESTS OF ACETEX. ACCORDINGLY, THE BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE ARRANGEMENT AND UNANIMOUSLY RECOMMENDS THAT HOLDERS OF ACETEX SECURITIES VOTE FOR THE ARRANGEMENT RESOLUTIONS AT THE MEETING. The Acetex Board of Directors came to these determinations based on, among other things, the opinion of Acetex's financial adviser, GMP that the consideration to be received under the Arrangement in exchange for the Acetex Securities was fair, from a financial point of view to Acetex Securityholders. In addition, Acetex's largest shareholders, Brooke N. Wade and Kenneth E. Vidalin, who collectively beneficially own, or exercise control or direction over, 29.36% of the votes to be cast at the Meeting have agreed to irrevocably support the Arrangement and vote in favour of the Arrangement Resolutions. See "INFORMATION CONCERNING THE ARRANGEMENT - Recommendation of the Board of Directors - and - Background and Reasons for the Arrangement". FAIRNESS OPINION GMP has provided its opinion to the Board of Directors that, as of October 27, 2004 (the date of the Arrangement Agreement), based upon and subject to the various considerations set forth in the GMP Fairness Opinion, the consideration payable to Acetex Securityholders pursuant to the Arrangement Agreement is fair from a financial point of view to the Acetex Securityholders. GMP expressed no opinion or recommendation as to how Acetex Securityholders should vote on the Arrangement Resolutions at the Meeting. See "INFORMATION CONCERNING THE ARRANGEMENT - Fairness Opinion" in this Circular and the complete text of the GMP Fairness Opinion set out in Appendix D to this Circular, which should be read in its entirety. PROCEDURE FOR PAYMENT TO ACETEX SECURITYHOLDERS If the requisite approvals are obtained from the Acetex Securityholders, the Court and certain regulatory authorities, and the Arrangement is completed, HNA will acquire all of the outstanding Acetex Securities. For Acetex Securityholders (other than Acetex Securityholders who validly exercise their Dissent Rights or any Holdco in respect of which a valid Holdco Election has been made) to receive the consideration payable on the acquisition of Acetex Securities, Acetex Securityholders must complete and sign the enclosed Letter of Transmittal and return it together with, if applicable, the certificates representing their Acetex Shares and/or Acetex Warrants (only the Letter of Transmittal needs to be returned by Acetex Optionholders) to Computershare Trust Company of Canada in accordance with the instructions in the Letter of Transmittal. A security return envelope is enclosed to assist Acetex Securityholders in delivering their certificates. ARRANGEMENT AGREEMENT COVENANTS OF ACETEX The Arrangement Agreement provides that Acetex will carry on business in the normal and ordinary course subject to specified dollar amounts in respect of certain contracts and in certain cases subject to the prior written consent of HNA. COVENANTS OF HNA HNA has agreed to deposit with Computershare Trust Company of Canada all funds required to be paid by it pursuant to the Arrangement no later than twenty-four (24) hours before the Effective Date by way of a bank draft, wire transfer or other form of immediately available funds. 7 MUTUAL COVENANTS Each of Acetex and HNA have covenanted to co-operate with each other in obtaining all necessary consents, approvals and authorizations as are required in connection with the Arrangement. COVENANTS OF ACETEX REGARDING NON-SOLICITATION Pursuant to the Arrangement Agreement, Acetex has agreed that it will not directly or indirectly solicit, initiate, invite or encourage the initiation of or participation in any inquiries or proposals regarding an Acquisition Proposal or enter into any agreement related to any Acquisition Proposal. However, the Arrangement Agreement allows the Board of Directors a limited ability to consider, negotiate, approve or amend an agreement in respect of an unsolicited bona fide written Acquisition Proposal, subject to certain conditions as described below. See "THE ARRANGEMENT AGREEMENT" in this Circular and the complete text of the Arrangement Agreement which is attached as Appendix C). CONDITIONS IN FAVOUR OF BOTH ACETEX AND HNA The Arrangement Agreement is subject to certain customary conditions, including the following: (a) the Final Order shall have been granted in form and substance satisfactory to Acetex and HNA and shall not be set aside or modified in a manner unacceptable to the parties; (b) there shall be no action taken under any Laws or by any Governmental Entity, that: (i) makes illegal or otherwise directly or indirectly prohibits the Arrangement or any other transactions or agreements contemplated in the Arrangement Agreement or materially modifies the Arrangement or any other transactions or agreements contemplated in the Arrangement Agreement in a manner unacceptable to the parties, acting reasonably; or (ii) results in a judgment or assessment of damages, directly or indirectly, which is material to the transactions or agreements contemplated in the Arrangement Agreement; and (c) all consents, waivers, permits and approvals, including the regulatory approvals required or desirable in connection with the Arrangement and the transactions contemplated by the Arrangement Agreement shall have been obtained and/or, as applicable, any statutorily defined waiting periods shall have expired (See "INFORMATION CONCERNING THE ARRANGEMENT - Regulatory Matters"). CONDITIONS IN FAVOUR OF HNA The Arrangement Agreement provides that the obligation of HNA to complete the Arrangement is subject to the satisfaction on or before the Effective Date of a number of conditions, including the following, each of which may be waived by HNA: (a) the representations and warranties made by Acetex in the Arrangement Agreement are in the reasonable judgment of HNA true and correct in all material respects as of the Effective Date as if made on and as of such date (except to the extent such representations and warranties speak as of an earlier date or except as affected by transactions contemplated or permitted by the Arrangement Agreement or except where a representation and warranty is qualified by "in all material respects" or other similar materiality qualifiers, in which case such representation and warranty shall be true and correct) and Acetex shall have provided to HNA the certificate of a senior officer of Acetex certifying such accuracy on the Effective Date; (b) Acetex shall have complied in all material respects with its covenants under the Arrangement Agreement and Acetex shall have provided to HNA the certificate of a senior officer of Acetex certifying that Acetex has so complied with its covenants under the Arrangement Agreement; 8 (c) the Board of Directors shall have adopted all necessary resolutions, and all other necessary corporate actions shall have been taken by Acetex and its Subsidiaries to permit the consummation of the transactions contemplated by the Arrangement Agreement; (d) since the date of the Arrangement Agreement there shall have been no events, circumstances, conditions, changes or occurrences that individually, or in the aggregate, have had, or could reasonably be expected to have, a material adverse effect on the business, operations, assets, financial condition or results of operations of Acetex and any of its Subsidiaries taken as a whole, except any such effect resulting from or arising in connection with (i) the announcement of the Arrangement Agreement or the Arrangement (including any loss of customers which results from the announcement of the Arrangement Agreement), (ii) changes generally affecting the industries in which Acetex and its Subsidiaries operate that do not have a disproportionately adverse impact on Acetex and its Subsidiaries or (iii) changes in economic conditions generally that do not have a disproportionately adverse impact on Acetex and its Subsidiaries; and (e) rights of dissent shall not have been exercised, nor shall proceedings have been initiated to exercise such rights by Acetex Shareholders, Acetex Optionholders or Acetex Warrantholders which in the aggregate represent more than 10% of the outstanding capital stock of Acetex on a fully diluted basis. CONDITIONS IN FAVOUR OF ACETEX The Arrangement Agreement provides that the obligation of Acetex to complete the Arrangement is subject to the satisfaction, on or before the Effective Date, of a number of conditions, including the following, each of which may be waived by Acetex: (a) the representations and warranties made by HNA in the Arrangement Agreement are in the reasonable judgment of Acetex true and correct in all material respects as of the Effective Date as if made on and as of such date (except to the extent such representations and warranties speak as of an earlier date or except as affected by transactions contemplated or permitted by the Arrangement Agreement or except where a representation and warranty is qualified by "in all material respects" or other similar materiality qualifiers, in which case such representation and warranty shall be true and correct) and HNA shall have provided to Acetex the certificate of a senior officer of HNA certifying such accuracy on the Effective Date; and (b) HNA shall have complied in all material respects with its covenants under the Arrangement Agreement, and HNA shall have provided to Acetex the certificate of a senior officer of HNA certifying that HNA has so complied with its covenants under the Arrangement Agreement. There is no assurance that all of the conditions noted above will be satisfied or waived on a timely basis. The conditions noted above shall be conclusively deemed to have been satisfied, waived or released when with the agreement of Acetex and HNA, a certificate of arrangement in respect of the Plan of Arrangement is issued by the Registrar. TERMINATION AND PAYMENT OF FEES AND EXPENSES The Arrangement Agreement may be terminated by mutual written consent of Acetex and HNA at any time prior to the Effective Date. Either Acetex or HNA may terminate the Arrangement Agreement if: (a) the Interim Order is not granted on or before December 21, 2004 in form and substance satisfactory to HNA and Acetex or is set aside or modified in a manner unacceptable to HNA and Acetex on appeal or otherwise; (b) the Acetex Arrangement Resolutions are not passed at the Meeting on or before January 22, 2005 or such later date as may be permitted by the Arrangement Agreement, provided that Acetex may not terminate the Arrangement Agreement unless any applicable termination fee has been paid; and 9 (c) the Effective Date is not on or before August 31, 2005 or other date as the parties may mutually agree upon. HNA or Acetex may terminate the Arrangement Agreement prior to the Effective Date if any condition in the respective party's favour has not been satisfied at or prior to the date required for performance. The Arrangement Agreement may be terminated by Acetex upon the entering into of a definitive agreement with respect to a Superior Proposal in accordance with the applicable provisions of the Arrangement Agreement following the failure of the Arrangement Resolutions to be passed at the Meeting, provided Acetex has paid the termination fee noted below. The Arrangement Agreement may be terminated by HNA at any time following the occurrence of an HNA Payment Event as defined below. Acetex is required to pay a termination fee to HNA in the amount of $10,000,000 if: (a) the Board of Directors withdraws, qualifies or changes any of its recommendations or determinations in support of the Arrangement in a manner permitted in accordance with applicable provisions of the Arrangement Agreement; (b) an Acquisition Proposal is publicly announced, proposed, offered or made to the Acetex Securityholders or to Acetex, and (i) such Acquisition Proposal has not expired or been withdrawn at the time of the Acetex Meeting and (ii) the Acetex Securityholders do not approve the Arrangement Resolutions; or (c) Acetex accepts, approves, recommends or enters into any agreement with respect to an Acquisition Proposal in accordance with the applicable provisions of the Arrangement Agreement. Each of the above is an "HNA Payment Event". See "THE ARRANGEMENT AGREEMENT" and Appendix C for the full text of the Arrangement Agreement. ASSIGNMENT The Arrangement Agreement may not be assigned by either party without the prior written consent of the other party; provided that, Celanese may assign its rights and obligations under the Arrangement Agreement to any of its affiliates, provided that such affiliate agrees to be bound by the terms and conditions thereof and provided, further, that no such assignment shall relieve Celanese of any of its obligations under the Arrangement Agreement. Pursuant to this provision, Celanese has assigned its rights and obligations under the Arrangement Agreement to HNA, its indirect wholly-owned Subsidiary. Celanese has not been relieved of any of its obligations under the Arrangement Agreement. HNA has the right to further assign its rights and obligations under the Arrangement to another affiliate of Celanese. SUPPORT AGREEMENTS Pursuant to the Support Agreements, Brooke Wade and Ken Vidalin irrevocably agreed among other things: (a) to vote the Acetex Shares or Options, as applicable, held or controlled by them or over which they exercise direction in favour of the Arrangement Resolutions at the Meeting and against any matter or proposal which would delay or be inconsistent with the Arrangement; and (b) not to exercise their Dissent Rights in respect of the Arrangement Resolutions. Brooke Wade holds or controls 7,966,846 Acetex Shares representing 20.74% of the outstanding Acetex Securities. Ken Vidalin holds or controls 2,530,065 Acetex Shares and 781,088 Acetex Options representing 8.62% of the outstanding Acetex Securities. 10 DISSENT RIGHTS Pursuant to the Interim Order, a registered holder of Acetex Securities has a right to dissent with respect to the Arrangement Resolutions if Acetex receives c/o Burnet, Duckworth & Palmer LLP Suite 1400, 350 - 7th Ave. S.W., Calgary, Alberta T2P 3N9 Attention David W. Ross or Shannon Wray, on or before 5:00 p.m. (Calgary time) on the Business Day prior to the Meeting, a written objection and such Acetex Securityholder complies with Section 191 of the ABCA, as modified by the Interim Order. Provided the Arrangement becomes effective, each dissenting Acetex Securityholder will be entitled to be paid fair value of the Acetex Securities in respect of which the Acetex Securityholder dissents in accordance with Section 191 of the ABCA, as modified by the Interim Order. The statutory provisions governing the right of dissent are technical and complex. Failure to strictly comply with the requirements set forth in Section 191 of the ABCA, as modified by the Interim Order, may result in the loss of any right of dissent. PERSONS WHO ARE BENEFICIAL OWNERS OF ACETEX SECURITIES REGISTERED IN THE NAME OF A BROKER, CUSTODIAN, NOMINEE OR OTHER INTERMEDIARY WHO WISH TO DISSENT, SHOULD BE AWARE THAT ONLY THE REGISTERED HOLDER OF SUCH ACETEX SECURITIES IS ENTITLED TO DISSENT. Accordingly, a beneficial owner of Acetex Securities desiring to exercise the right of dissent must make arrangements for such securities beneficially owned to be registered in such securityholder's name prior to the time the written objection to the resolutions approving the Arrangement is required to be received by Acetex or alternatively, make arrangements for the registered Acetex Securityholder of such securities to dissent on such Acetex Securityholder's behalf. See the information under the heading "DISSENTING SECURITYHOLDER RIGHTS" in this Circular for a description of the Dissent Procedures and also see Appendices B and E for a copy of the Interim Order and the provisions of Section 191 of the ABCA, respectively. IT IS A CONDITION OF THE ARRANGEMENT THAT NOT MORE THAN 10% OF ACETEX SECURITYHOLDERS SHALL HAVE EXERCISED RIGHTS OF DISSENT IN RELATION TO THE ARRANGEMENT. See "THE ARRANGEMENT AGREEMENT - Conditions to Closing". RISK FACTORS Acetex and Acetex Securityholders are subject to material risks if the Arrangement is not completed. These include the risk that trading prices for Acetex Shares may decline and an alternative purchaser or other business combination may not be available. See "RISK FACTORS". 11 INFORMATION CONCERNING THE MEETING AND PROXIES THE MEETING The Meeting is being called pursuant to the Interim Order of the Court to seek the requisite approval of Acetex Securityholders to the Arrangement in accordance with Section 193 of the ABCA and will be held on January 12, 2005 at 10:00 a.m. (Pacific Time) at the Pan Pacific Hotel, 999 Canada Place, Vancouver, British Columbia, and at any adjournment thereof for the purposes set forth in the accompanying Notice of Meeting. RECORD DATE, VOTING ACETEX SECURITIES AND PRINCIPAL HOLDERS The Board of Directors has fixed the Record Date for the Meeting as at 5:00 p.m. (Calgary time) on December 10, 2004. The number of Acetex Securities entitled to be voted on each matter to be acted on at the Meeting as of the Record Date was 34,340,319 Acetex Shares; 848,112 Acetex Warrants and 3,226,066 Acetex Options for a total of 38,414,497 Acetex Securities. Each Acetex Shareholder is entitled to one vote for each Acetex Share shown as registered in such shareholder's name on the list of Acetex Shareholders prepared as of the Record Date. Each Acetex Warrantholder is entitled to one vote for each Acetex Share issuable pursuant to each Acetex Warrant shown as registered in such warrantholder's name on the list of Acetex Warrantholders prepared as of the Record Date. Each Acetex Optionholder is entitled to one vote for each Acetex Share issuable pursuant to each Acetex Option shown as registered in such optionholder's name on the list of Acetex Optionholders prepared as of the Record Date. However, in the event of any transfer of Acetex Shares or Acetex Warrants by any Acetex Securityholder after such date, the transferee is entitled to vote those Acetex Shares or Acetex Warrants if the transferee produces properly endorsed share certificates in respect of the Acetex Shares or original certificates in respect of the Acetex Warrants or otherwise establishes that the transferee owns the Acetex Shares or Acetex Warrants, and demands, not later than ten days before the Meeting that Computershare Trust Company of Canada as transfer agent at 100 University Avenue, 9th Floor, Toronto, Ontario M5J 2Y1 include his or her name on the list of Persons entitled to attend and vote at the Meeting. To the knowledge of the directors and officers of Acetex, the only person who beneficially owns or exercises control or direction over Acetex Securities carrying more than 10% of the votes attached to all the Acetex Securities entitled to be voted at the Meeting is Brooke N. Wade who owns or controls 7,966,846 Acetex Shares representing 20.74% of the votes attributed to all of the issued and outstanding Acetex Securities and 23.20% of the votes attributed to all of the issued and outstanding Acetex Shares. SOLICITATION OF PROXIES BY MANAGEMENT THIS CIRCULAR IS FURNISHED IN CONNECTION WITH THE SOLICITATION OF PROXIES BY THE MANAGEMENT OF ACETEX TO BE USED AT THE MEETING. Solicitations of proxies will be primarily by mail, but may also be by newspaper publication, in person or by telephone, fax or oral communication by directors, officers, employees or agents of Acetex who will be specifically remunerated therefor. All costs of the solicitation will be borne by Acetex; provided that in certain circumstances HNA shall reimburse Acetex for fifty percent (50%) of the reasonable costs actually incurred by Acetex associated with the solicitation of proxies for the approval of the Arrangement Resolutions in accordance with the Circular and the Interim Order in favour of the approval of the Arrangement Resolutions. Acetex has not made a decision to engage proxy solicitation agents to encourage the return of completed proxies by Securityholders and to solicit proxies in favour of the Arrangement Resolutions. Acetex may however do so, and if it does, it expects that the costs in respect of such services will not exceed Cdn $100,000. APPOINTMENT OF PROXYHOLDERS AND REVOCATION OF PROXIES The Persons named in the enclosed forms of proxy are directors and officers of Acetex. A SECURITYHOLDER DESIRING TO APPOINT A PERSON (WHO NEED NOT BE AN ACETEX SECURITYHOLDER) TO REPRESENT SUCH ACETEX SECURITYHOLDER AT THE MEETING OTHER THAN THE PERSONS DESIGNATED IN THE ACCOMPANYING FORMS OF PROXY MAY DO SO EITHER BY 12 INSERTING SUCH PERSON'S NAME IN THE BLANK SPACE PROVIDED IN THE APPROPRIATE FORM OF PROXY OR BY COMPLETING ANOTHER FORM OF PROXY. The applicable form of proxy, to be acted upon, must be deposited with Acetex, (c/o its agent, Computershare Trust Company of Canada 100 University Avenue, 9th Floor, Toronto, Ontario M5J 2Y1), by 5:00 p.m. (Toronto time) on the last Business Day prior to the date on which the Meeting or any adjournment thereof is held, or with the chair of the Meeting on the day of the Meeting or any adjournment thereof. An Acetex Securityholder who has given a proxy may revoke it by depositing an instrument in writing (including another proxy) executed by the holder or by the holder's attorney authorized in writing at the above mentioned office of Computershare Trust Company of Canada at any time up to and including 5:00 p.m. (Toronto time) on the last Business Day prior to the day the Meeting or any adjournment thereof is to be held, or with the chair of the Meeting on the day of the Meeting at any time before it is exercised on any particular matter or in any other manner permitted by Law including attending the Meeting in person. VOTING BY PROXIES The Persons named in the accompanying forms of proxy will vote the Acetex Securities in respect of which they are appointed in accordance with the direction of the Acetex Securityholder appointing them. IN THE ABSENCE OF SUCH DIRECTION, SUCH ACETEX SECURITIES WILL BE VOTED FOR THE APPROVAL OF THE ARRANGEMENT RESOLUTIONS. Each of the enclosed forms of proxy confers discretionary authority upon the Persons named therein with respect to amendments or variations to matters identified in the Notice of Meeting, and with respect to any other matter which may properly come before the Meeting. As of the date of this Circular, management is not aware of any such amendment, variation or other matter proposed or likely to come before the Meeting. However, if any such amendment, variation or other matter properly comes before the Meeting, it is the intention of the Persons named in each of the enclosed forms of proxy to vote on such other business in accordance with their judgment. ADVICE TO BENEFICIAL SHAREHOLDERS The information set forth in this section is of significant importance to many Acetex Shareholders, as a substantial number of them do not hold shares in their own name. Shareholders who do not hold shares in their own name ("Beneficial Shareholders") should note that only proxies deposited by Acetex Shareholders whose names appear on the records of Acetex as the registered holders of Acetex Shares can be recognized and acted upon at the Meeting. If Acetex Shares are listed in an account statement provided to a Beneficial Shareholder by a broker, then in almost all cases those shares will not be registered in the Beneficial Shareholder's name on the records of Acetex. Such shares will more likely be registered under the names of the Beneficial Shareholder's broker or an agent of that broker. In Canada, the majority of such shares are registered under the name of CDS & Co. (the registration name for The Canadian Depositary for Securities, which acts as nominee for many Canadian brokerage firms). Acetex Shares held by brokers or their agents or nominees can only be voted (for or against resolutions) upon the instructions of the Beneficial Shareholder. Without specific instructions, brokers and their agents and nominees are prohibited from voting shares for the broker's clients. THEREFORE, BENEFICIAL SHAREHOLDERS SHOULD ENSURE THAT INSTRUCTIONS RESPECTING THE VOTING OF THEIR ACETEX SHARES ARE COMMUNICATED TO THE APPROPRIATE PERSON. Applicable regulatory policy requires intermediaries/brokers to seek voting instructions from Beneficial Shareholders in advance of shareholders' meetings. Every intermediary/broker has its own mailing procedures and provides its own return instructions to clients, which should be carefully followed by Beneficial Shareholders in order to ensure that their shares are voted at the Meeting. The form of proxy supplied to a Beneficial Shareholder by its broker (or the agent of the broker) is similar to the form of proxy provided to registered Acetex Shareholders by Acetex. However, its purpose is limited to instructing the registered Acetex Shareholder (the broker or agent of the broker) how to vote on behalf of the Beneficial Shareholder. The majority of brokers now delegate responsibility for obtaining instructions from clients to ADP Investor Communications ("ADP"). ADP typically asks Beneficial Shareholders to return the proxy forms to ADP. ADP then tabulates the results of all instructions received and 13 provides appropriate instructions respecting the voting of shares to be represented at the Meeting. A BENEFICIAL SHAREHOLDER RECEIVING AN ADP PROXY CANNOT USE THAT PROXY TO VOTE ACETEX SHARES DIRECTLY AT THE MEETING - THE PROXY MUST BE RETURNED TO ADP WELL IN ADVANCE OF THE MEETING IN ORDER TO HAVE THE ACETEX SHARES VOTED. Although a Beneficial Shareholder may not be recognized directly at the Meeting for the purposes of voting Acetex Shares registered in the name of his broker (or agent of the broker), a Beneficial Shareholder may attend at the Meeting as proxyholder for the registered Acetex Shareholder and vote the Acetex Shares in that capacity. Beneficial Shareholders who wish to attend at the Meeting and indirectly vote their Acetex Shares as proxyholder for the registered Acetex Shareholder should enter their own names in the blank space on the instrument of proxy provided to them and return the same to their broker (or the broker's agent) in accordance with the instructions provided by such broker (or agent), well in advance of the Meeting. PROCEDURE AND VOTES REQUIRED Pursuant to the Interim Order, the Arrangement Resolutions must be approved by at least two-thirds of the votes cast by Acetex Securityholders, in person or by proxy at the Meeting, voting together as a single class. Notwithstanding the foregoing, the Arrangement Resolutions authorize the Board of Directors, without further notice to or approval of the Acetex Securityholders, subject to the terms of the Arrangement and the Arrangement Agreement (and subject to the consent of HNA where required), to amend or terminate the Arrangement Agreement or the Plan of Arrangement or rescind the Arrangement Resolutions at any time prior to the filing of Articles of Arrangement giving effect to the Arrangement. See Appendix A to this Circular for full text of the Arrangement Resolutions. INFORMATION CONCERNING THE ARRANGEMENT THE ARRANGEMENT The Plan of Arrangement provides for the acquisition of all the Acetex Securities by HNA. Acetex Securityholders are urged to read the Plan of Arrangement in its entirety. The Plan of Arrangement is attached as Schedule A to the Arrangement Agreement, which is attached as Appendix C to this Circular. By approving the Arrangement Resolutions, Acetex Securityholders will approve the acquisition of all the Acetex Securities by HNA. Acetex Securityholders (other than Acetex Securityholders who validly exercise their Dissent Rights or any Holdco in respect of which a valid Holdco Election has been made) will receive, as applicable, from HNA consideration (without interest) as follows: (a) for each Acetex Share $9.00 in cash; (b) for each Acetex Warrant $9.00 in cash less the exercise price of such Acetex Warrant; and (c) for each Acetex Option the greater of (i) $9.00 in cash less the exercise price of such Acetex Option and (ii) one cent. An Acetex Shareholder who qualifies as a Holdco may elect to have all issued and outstanding shares of the Holdco transferred to HNA in exchange for $9.00 cash per Holdco Share, provided that, among other things, the Holdco enters into a satisfactory Holdco Agreement. For more information, see "ARRANGEMENT MECHANICS - The Holdco Election". The completion of the Arrangement is conditional upon, among other things, approval of the Arrangement Resolutions by at least two-thirds of the votes cast by Acetex Securityholders present in person or represented by proxy and entitled to vote at the Meeting. The Arrangement is subject to Court and certain regulatory approvals and satisfaction or waiver of the conditions contained in the Arrangement Agreement. The Arrangement will become effective following the filing of the Articles of Arrangement with the Registrar under the ABCA. 14 The Acetex Shares are expected to be delisted from the TSX following the Effective Date. Acetex will also seek to be deemed to have ceased to be a reporting issuer in those jurisdictions in Canada in which it is currently a reporting issuer. Following the completion of the Arrangement, Acetex will govern itself in a manner consistent with its status as a corporation that is not a reporting issuer in Canada and that is not publicly traded or listed on any stock exchange. BACKGROUND AND REASONS FOR THE ARRANGEMENT The provisions of the Arrangement Agreement are the result of arm's length negotiations conducted among representatives of Acetex, Blackstone, Celanese Ltd. and their advisers. Blackstone and Celanese Ltd. are affiliates of HNA. The following is a summary of the meetings, negotiations, discussions and actions between the parties that preceded the execution and public announcement of the Arrangement Agreement. In mid June of 2004, UBS took steps to organize a meeting between representatives of Blackstone, Celanese Ltd. and Acetex with a view to a possible transaction. Prior to the meeting, a confidentiality agreement dated June 24, 2004 was entered into between Acetex, Blackstone and Celanese Ltd. On June 24, 2004, a meeting took place in Vancouver at which time Acetex gave Blackstone and Celanese Ltd. a presentation on its business. Blackstone indicated that it would proceed to consider a possible transaction and would make preliminary due diligence inquiries regarding Acetex. Blackstone indicated it would contact Acetex at a later date and indicate its intentions, if any. On July 27, 28 and 29, 2004 the Board of Directors of Acetex held a strategic retreat and considered a possible transaction with Blackstone. The Board of Directors reviewed, among other factors Acetex's competitive challenges, its requirement for additional capital spending for its Saudi Arabia project, the low market value for its common shares, its small public float and financial and strategic advice from UBS. On August 4, 2004 Blackstone indicated it might be prepared to consider a transaction to acquire all of the issued Acetex Securities pending further due diligence. Discussions were held as to price but no consensus was reached. On August 11, 2004 Blackstone affirmed that it was still interested in discussing a possible transaction with Acetex but indicated that discussions would be postponed while it investigated another transaction. On September 15, 2004 Blackstone indicated it wished to resume discussions with Acetex with respect to a possible transaction. On September 17, 2004 Acetex, at the request of the TSX issued a press release indicating it was in discussions with respect to a possible transaction. On September 20, 2004 Acetex met with representatives of Blackstone and Celanese Ltd. in New York to review requirements for regulatory consents that would be needed if there were to be an acquisition transaction. On October 4, 2004 GMP met with Acetex and was apprised of the potential transaction with Blackstone. On October 12, Acetex sent a draft of the Arrangement Agreement to Blackstone and Celanese Ltd. for consideration and after negotiation the terms of the draft Arrangement Agreement, including price, were substantially finalized on October 20, 2004. On October 14, 2004 Acetex asked GMP to consider whether it could give a fairness opinion with respect to the Arrangement. The Board of Directors of Acetex met formally on October 22, 2004 and reviewed a draft of the proposed Arrangement Agreement, a presentation of UBS and a draft fairness opinion of GMP. The Board of Directors also 15 discussed the terms of the draft Arrangement Agreement and proposed Support Agreements with Burnet, Duckworth & Palmer LLP, solicitors for Acetex. At this meeting the Board of Directors approved the draft Arrangement Agreement and authorized the management of Acetex to finalize the terms of the Arrangement Agreement. On October 25, 2004 Acetex finalized the terms of its engagement with each of UBS and GMP. Acetex and Blackstone finalized the terms and conditions of the Arrangement Agreement and executed the same on October 27, 2004. RECOMMENDATION OF THE BOARD OF DIRECTORS THE BOARD OF DIRECTORS HAS UNANIMOUSLY DETERMINED THAT THE ARRANGEMENT IS FAIR TO ACETEX SECURITYHOLDERS AND IS IN THE BEST INTERESTS OF ACETEX. ACCORDINGLY, THE BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE ARRANGEMENT AND UNANIMOUSLY RECOMMENDS THAT ACETEX SECURITYHOLDERS VOTE IN FAVOUR OF THE ARRANGEMENT RESOLUTIONS AT THE MEETING. In reaching its determination and making this recommendation, the Board of Directors considered a number of factors, including the following: (a) information concerning the business, operations, property, assets, financial condition, operating results and prospects of Acetex; (b) current industry, economic and marketing conditions and trends and the future prospects of the industry in which Acetex operates; (c) the fact that the consideration per Acetex Share offered by HNA of $9.00 represented a 26% premium over the 30 day weighted average trading price preceding September 17, 2004, being the day prior to the announcement by Acetex of a possible transaction; (d) the GMP Fairness Opinion to the effect that, as of the date of the Arrangement Agreement and subject to the limitations set out therein, the consideration to be received by Acetex Securityholders pursuant to the Arrangement Agreement is fair from a financial point of view to Acetex Securityholders which opinion was confirmed in writing as of October 27, 2004 and is reproduced in full as Appendix D to this Circular; (e) the small public float of Acetex common shares and the liquidity the Arrangement will provide to the Acetex Securityholders; (f) the requirement that the Arrangement be approved by special resolutions passed by at least two-thirds of the votes cast in person or by proxy at the Meeting by Acetex Securityholders voting together as a single class, and by the Court which, Acetex is advised, will consider, among other things, the fairness of the Arrangement to the Acetex Securityholders; (g) the terms and conditions of the Arrangement Agreement generally, including the amount of, and circumstances in which, a termination fee is payable by Acetex, and the fact that the terms of the Arrangement Agreement do not prevent the Board of Directors from accepting a Superior Proposal in certain circumstances; (h) the agreement by Brooke N. Wade and Ken Vidalin (effectively representing 29.36% of the issued and outstanding Acetex Securities ) to vote in favour of the Arrangement Resolutions; (i) the risks associated with, as an alternative to the Arrangement, continuing to execute Acetex's strategic plans as an independent entity including Acetex's competitive challenges and its capital requirements associated with the Saudi Project; and 16 (j) pursuant to the Interim Order, Acetex Securityholders have the right to dissent and be paid the fair value of their Acetex Securities. The Board of Directors unanimously recommends that Acetex Securityholders vote FOR the Arrangement Resolutions at the Meeting. Each of the directors of Acetex has advised Acetex that he intends to vote the Acetex Shares and any Acetex Options held by him in favour of the Arrangement Resolutions. In considering the Arrangement, the Acetex Board of Directors recognized that there were certain risks associated with the Arrangement, including the risk that the Arrangement may not be completed and the factors set out or referred to in this Circular under "RISK FACTORS". However, the Acetex Board of Directors concluded that the positive factors associated with the Arrangement outweigh those risks, although there can be no assurances in this regard. The foregoing discussion of the information and factors considered and given weight by the Board of Directors is not intended to be exhaustive, but is believed to include all material factors considered by the Board of Directors. In addition, in reaching the determination to approve and recommend the Arrangement, the Board of Directors did not assign any relative or specific weights to the foregoing factors which were considered, and individual directors may have given different weights to different factors. The Board of Directors is, however, unanimous in its recommendation to the Acetex Securityholders that the Arrangement Resolutions be approved at the Meeting. FINANCIAL ADVISER In connection with Acetex's consideration of various strategic alternatives, Acetex retained UBS as its financial adviser. UBS was engaged by Acetex to assist with considering and analysing various strategic alternatives, including possible acquisition proposals. In addition, UBS was engaged to advise and assist Acetex in negotiating a possible merger, sale or other strategic transaction. UBS will receive a customary fee for its services, a significant portion of which is contingent upon the consummation of the Arrangement. In addition, Acetex has agreed to indemnify UBS for certain liabilities arising out of its engagement. UBS has, in the past, provided financial advisory services to Acetex and has received fees for the rendering of such services. FAIRNESS OPINION Acetex also engaged GMP to provide an opinion as to the fairness of the Arrangement, from a financial point of view, to holders of Acetex Securities. The full text of the GMP Fairness Opinion, which sets forth, among other things, assumptions made, procedures followed, matters considered and limitations on the scope of the review undertaken by GMP in rendering its fairness opinion is attached as Appendix D to this Circular. Acetex Securityholders are urged to read the GMP Fairness Opinion carefully and in its entirety. The GMP Fairness Opinion addresses only the fairness, from a financial point of view, of the aggregate consideration to be received by holders of Acetex Securities pursuant to the Arrangement Agreement from a financial point of view, to holders of Acetex Securities and does not constitute a recommendation to any Acetex Securityholder as to how such Person should vote at the Meeting. The summary of the GMP Fairness Opinion set forth in this Circular is qualified in its entirety by reference to the full text of the GMP Fairness Opinion. GMP has provided its written consent to the inclusion of the GMP Fairness Opinion in this Circular. Among other things, in preparing its fairness opinion, GMP reviewed the following: 1. certain publicly available business and financial information relating to Acetex, Blackstone and Celanese Ltd. considered by GMP to be relevant; 17 2. certain public information relating to the business, financial performance and stock trading history of Acetex and compared them with those of other selected publicly traded companies considered by GMP to be relevant; 3. research reports prepared by equity research analysts on Acetex and the worldwide chemicals industry; 4. the financial terms of the Arrangement with the financial terms of certain other transactions considered by GMP to be relevant; 5. the PowerPoint presentation given by Acetex to attendees of Credit Suisse First Boston's Chemicals conference held on September 20, 2004; 6. discussions of the business, financial condition and prospects for Acetex before and after giving effect to the Arrangement with certain members of senior management of Acetex, its advisers and outside counsel; 7. the draft Arrangement Agreement dated October 25, 2004; 8. all press releases issued by The Blackstone Group, Acetex and Celanese Ltd. for the last 3 fiscal years; 9. a schedule of Common Shares and convertible securities of Acetex outstanding as at September 30, 2004; 10. a transcript of the conference call held by Acetex on April 20, 2004, to discuss the joint venture with National Petrochemical Industrialization Company (TASNEE Petrochemical) to construct facilities in Jubail, Kingdom of Saudi Arabia; 11. the business plans, forecasts and budgets prepared by management of Acetex for the fiscal years ended 2004 and 2005; 12. draft memorandum written by Law & Economics Consulting Group (LECG) dated September 16, 2004, with an analysis of the geographic markets for Acetex's products; 13. public information with respect to transactions of a nature comparable to the Arrangement which GMP considered to be relevant; and 14. other such corporate, industry and financial market information, investigations and analyses as GMP considered necessary or appropriate under the circumstances. In preparing the GMP Fairness Opinion, GMP assumed and relied on the accuracy, completeness and fair presentation of all information supplied or otherwise made available to GMP, discussed with or reviewed by or for GMP, or publicly available, and has not assumed any responsibility for independently verifying such information. With respect to the financial forecast information furnished to or discussed with GMP by Acetex, GMP assumed that such financial forecast information was reasonably prepared and reflected the best currently available estimates and judgments of Acetex's management as to the expected future financial performance of Acetex. The GMP Fairness Opinion is necessarily based on market, economic and other conditions as they existed and were able to be evaluated on, and the information made available to it as of, October 27, 2004. For providing the GMP Fairness Opinion, GMP has been paid a fixed fee which is not contingent upon the consummation of the Arrangement. GMP will also receive a fee for advisory services which have been and will be provided in connection with the Arrangement which is contingent upon the consummation of the Arrangement. In addition, Acetex has agreed to indemnify GMP for certain liabilities arising out of its engagement. GMP has, in the past, provided financial advisory services to Acetex and has received fees for the rendering of such services. On the basis of and subject to the foregoing, GMP is of the opinion that the consideration payable by HNA to Acetex Securityholders is fair from a financial point of view to such Acetex Securityholders. 18 INTERESTS OF CERTAIN PERSONS OR COMPANIES IN MATTERS TO BE ACTED UPON AND INTERESTS OF INFORMED PERSON IN MATERIAL TRANSACTIONS Directors and Officers of Acetex own beneficially, directly or indirectly, or exercise control or direction over, an aggregate of 11,149,904 Acetex Shares and 2,246,486 Acetex Options representing approximately 34.87% of the outstanding Acetex Securities. Each of the Directors and Officers has indicated an intention to vote all of the Acetex Shares and Acetex Options owned by them in favour of the Arrangement Resolutions. All unvested Acetex Options will become vested on completion of the Arrangement. The Executive Officers will be entitled to certain payments upon change of control or involuntary termination following a change of control as discussed under "INFORMATION ABOUT ACETEX - Termination of Employment, Change in Responsibilities and Employment Contracts". The Human Resources and Compensation Committee of the Board of Directors has determined that the benefits (if any) to be received by senior officers of Acetex as a consequence of the Arrangement do not exceed 5% of the amount to be received by such officers pursuant to the Arrangement. COURT APPROVAL OF THE ARRANGEMENT AND COMPLETION OF THE ARRANGEMENT An arrangement under the ABCA requires approval by the Court pursuant to the Final Order. On December 8, 2004, Acetex obtained the Interim Order providing for the calling and holding of the Meeting and other procedural matters. A copy of the Interim Order is attached hereto as Appendix B. Subject to the terms of the Arrangement Agreement and if the Arrangement Resolutions are approved at the Meeting, Acetex will make an application to the Court for the Final Order at the Court House, 611 - 4th Street S.W., Calgary, Alberta on January 13, 2005, at 1:30 p.m. (Calgary time) or as soon thereafter as counsel may be heard. The Notice of Petition and Interim Order accompanies this Circular. Any Acetex Securityholder or other interested party desiring to support or oppose the Petition with respect to the Arrangement may appear at the hearing in person or by counsel for that purpose, subject to filing with the Court and serving on Acetex, on or before 12:00 noon (Calgary time) on January 7, 2005 a notice of intention to appear setting out their address for service in Alberta together with any evidence or materials which are to be presented to the Court. Service of such notice on Acetex is required to be effected by service upon the solicitors of Acetex, Burnet, Duckworth & Palmer LLP, Barristers and Solicitors, 1400, 350 - 7th Avenue S.W., Calgary, Alberta T2P 3N9, Attention: David W. Ross or Shannon Wray. Acetex has been advised by its counsel that the Court has broad discretion under the ABCA when making orders with respect to the Arrangement and the Court, in hearing the application for the Final Order, will consider, among other things, the fairness of the Arrangement to the Acetex Securityholders and any other interested party as the Court determines appropriate. The Court may approve the Arrangement either as proposed or as amended in any manner the Court may direct, subject to compliance with such terms and conditions, if any, as a Court may determine appropriate. Either HNA or Acetex may determine not to proceed with the Arrangement in the event that any amendment ordered by the Court is not satisfactory to that party. Assuming the Final Order is granted and the other conditions to closing contained in the Arrangement Agreement are satisfied or waived, it is anticipated that Articles of Arrangement will be filed with the Registrar under the ABCA to give effect to the Arrangement and the various other documents necessary to consummate the transactions contemplated under the Arrangement Agreement will be executed and delivered. At least twenty-four (24) hours prior to the Effective Date, HNA will deposit with Computershare Trust Company of Canada sufficient monies to satisfy HNA's obligations under the Plan of Arrangement Subject to the foregoing (including the satisfaction of other conditions precedent), it is expected that the Effective Time will occur as soon as practicable after the requisite Acetex Securityholder approvals have been obtained, the Final Order is granted and all regulatory approvals, including approvals with respect to all applicable competition Law and antitrust Laws, have been obtained. 19 REGULATORY MATTERS Under the Arrangement Agreement, HNA and Acetex have both agreed to apply for and to obtain all regulatory approvals necessary or advisable in connection with the transaction contemplated by the Arrangement Agreement. It is not expected that all such regulatory approvals will be obtained prior to the Meeting. U.S. ANTITRUST FILING Under the HSR Act, a transaction may not be completed until each party has notified the transaction to the Federal Trade Commission and the Antitrust Division of the Department of Justice (the "U.S. Regulators") and the required waiting period has expired or terminated. Under the HSR Act, the transaction may not be completed until 30 days after the initial filing (unless early termination of this waiting period is granted) or, if the U.S. Regulators issue a Second Request for additional information, 30 days after each of HNA and Acetex have certified their substantial compliance with the Second Request (unless this period is shortened by a grant of early termination). It is a condition to the completion of the Arrangement that the applicable waiting period under the HSR Act expires or is terminated. During or after the statutory waiting periods, and even after the completion of the Arrangement, U.S. federal or state governmental authorities can seek to challenge the Arrangement as they deem necessary or desirable in the public interest. EUROPEAN UNION ANTITRUST FILING Under the EC Merger Regulation, a transaction may not be completed until the transaction has been formally notified to the European Commission and the European Commission has issued a decision clearing the closing. Under the EC Merger Regulation, the European Commission must issue a decision either clearing the closing of the transaction or opening an in-depth investigation within 25 working days of formal notification of the transaction by the parties. If the parties timely offer remedies during this first phase, the European Commission's deadline for issuing such a decision is extended by an additional 10 working days. Should the European Commission decide to open an in-depth investigation, the EC Merger Regulation requires that the European Commission issue a final decision either approving or disapproving the closing of the transaction within 90 working days of opening this second phase investigation. If the parties timely offer remedies during this second phase, the European Commission's deadline for issuing such a decision is extended by an additional 15 working days. In addition, the parties may request one 20 working day extension of this second phase investigation. Likewise, the European Commission can, with the consent of the parties, extend the second phase investigation by 20 working days. It is a condition to the completion of the Arrangement that the European Commission issues a decision approving the closing of the Arrangement. HNA and Acetex are currently engaged in usual and customary pre-notification discussions with the European Commission in advance of making a formal notification. CANADIAN COMPETITION ACT FILING The Competition Act requires that parties to certain transactions that exceed specified size thresholds provide to the Commissioner of Competition ("Commissioner") prior notice of, and information relating to, the transaction. Parties to the transaction must await the expiration of a prescribed "waiting period" prior to completing the transaction unless the Commissioner has (1) issued an advance ruling certificate ("ARC") under Section 102 of the Competition Act advising the parties that the transaction will not be challenged under Section 92 of the Competition Act or (2) waived the notification obligation under Section 113(c) of the Competition Act. It is a condition to the completion of the Arrangement that HNA and Acetex (1) receive an ARC from the Commissioner or (2) that the Commissioner waive the obligation to notify the Commissioner and supply information because substantially similar information was previously supplied in relation to a request for an ARC, or that the waiting period under section 123 of the Competition Act has expired, and (3) Acetex and HNA shall have been advised in writing by the Commissioner that she has determined not to make an application for an order under 20 section 92 of the Competition Act in respect of the transactions contemplated by the Arrangement Agreement and any terms and conditions attached to any such advice shall be acceptable to Acetex and HNA. INVESTMENT CANADA ACT APPLICATION Under the Investment Canada Act, certain transactions involving the acquisition of control of a Canadian business by a non-Canadian are subject to review and cannot be implemented unless the Minister responsible for the Investment Canada Act (the "Minister") is satisfied that the transaction is likely to be of net benefit to Canada. If a transaction is subject to the review requirement (a "Reviewable Transaction"), an application for review must be filed with the Investment Review Division of Industry Canada prior to the implementation of the Reviewable Transaction. The Minister is then required to determine whether the Reviewable Transaction is likely to be of net benefit to Canada taking into account, among other things, certain factors specified in the Investment Canada Act and any written undertakings that may have been given by the applicant. The Investment Canada Act contemplates an initial review period of up to 45 days after filing; however, if the Minister has not completed the review by that date, the Minister may unilaterally extend the review period by up to 30 days (or such longer period as may be agreed to by the applicant) to permit completion of the review. As the acquisition of control of Acetex contemplated by the Arrangement is a Reviewable Transaction, HNA must file an application for review under the Investment Canada Act. The transactions contemplated by the Arrangement must be notified to antitrust regulators in Brazil, China and Turkey. The final consummation of the Arrangement is also contingent upon obtaining all other consents, waivers, permits and approvals of any Governmental Entity or other Person, and the expiry or termination of any waiting periods reasonably required or desirable in connection with the consummation of the transactions contemplated by the Arrangement shall have been obtained and reasonably satisfactory evidence thereof shall have been delivered to Acetex and HNA. ARRANGEMENT MECHANICS DEPOSIT OF FUNDS BY HNA No later than twenty-four (24) hours before the Effective Time, HNA shall deposit with Computershare Trust Company of Canada, as agent for the benefit of the Acetex Securityholders and Holdco Shareholders, as applicable, who shall ultimately receive payments for Acetex Shares, Acetex Warrants, Acetex Options or Holdco Shares sufficient monies to satisfy HNA's obligations under the Plan of Arrangement. After the Effective Time the required payments will be made to Acetex Securityholders and Holdco Shareholders by Computershare Trust Company of Canada upon receipt of certificates in respect of Acetex Shares or Participating Holdco Shares and in the case of Acetex Warrants, warrant certificates, in all cases together with a properly completed and executed Letter of Transmittal and such other documents and instruments as may reasonably be required.

24 (xii) fail to use reasonable commercial efforts, or cause each of its Subsidiaries to fail to use its reasonable commercial efforts, to preserve intact their respective business organizations and goodwill, to keep available the services of its officers and employees as a group and to maintain satisfactory relationships with suppliers, agents, distributors, customers and others having business relationships with it or its Subsidiaries; (xiii) it shall not settle or compromise any claim brought by any present, former or purported holder of any of its securities in connection with the transactions contemplated by the Arrangement Agreement prior to the Effective Date without the prior written consent of HNA; (xiv) except in the usual and ordinary course of business and consistent with past practice or except as disclosed to HNA, it and its Subsidiaries shall not (i) enter into any new contract or modify any existing contract involving amounts in excess of U.S.$5,000,000 and (ii) shall not terminate any existing contract involving amounts in excess of U.S.$1,000,000; and (xv) subject to confidentiality obligations it will keep HNA fully informed as to the material decisions required to be made or actions required to be taken with respect to the operation of its businesses. Each of Acetex and HNA have covenanted to co-operate with each other in (i) obtaining all necessary consents, approvals and authorizations as are required to be obtained by each party under any applicable Law; (ii) effecting all necessary registrations and filings and submissions of information requested by Governmental Entities required to be effected by each party in connection with the Arrangement; and (iii) opposing, lifting or rescinding any injunction or restraining order or other order or action seeking to stop, or otherwise adversely affect the ability to consummate the Arrangement. COVENANTS REGARDING RECOMMENDATION OF BOARD OF DIRECTORS, NON-SOLICITATION AND HNA'S RIGHT TO MATCH Pursuant to the Arrangement Agreement, the Board of Directors may not change or withdraw its recommendation to the Acetex Securityholders in respect of the Arrangement, except to the extent permitted under Section 6.6 of the Arrangement Agreement and subject to the requirements set forth therein. Pursuant to the Arrangement Agreement, Acetex has agreed that neither it nor any of its Subsidiaries will directly or indirectly, through any officer, director, employee, representative or agent; solicit, initiate, invite or encourage the initiation of or participation in any inquiries or proposals regarding an Acquisition Proposal. However, the Board of Directors may, in accordance with the Arrangement Agreement, consider, negotiate, approve or recommend to the Acetex Securityholders an agreement in respect of an unsolicited bona fide written Acquisition Proposal: (a) (i) that is not subject to any financing condition and in respect of which any required financing has been demonstrated to the satisfaction of a majority of the Board of Directors, acting in good faith, to be reasonably likely to be obtained; (ii) which is not subject to a due diligence access condition which allows access to the books, records and personnel of Acetex or any of its Subsidiaries or their representatives (A) greater than that previously provided to HNA or (B) beyond 5:00 p.m. (Pacific Time) on the third business day after which access is afforded to the Person making the Acquisition Proposal (provided, however, the foregoing shall not restrict the ability of such Person to continue to review the information provided); (b) in respect of which a majority of the Board of Directors determines, after consultation with outside counsel, that in the exercise of its fiduciary duties under applicable Law it would be necessary for the Board of Directors to take such action in order to avoid breaching its fiduciary duties; and (c) which a majority of the Board of Directors determines in good faith, after consultation with financial advisers, if consummated in accordance with its terms, would result in a transaction more favourable to the Acetex Securityholders (in their capacity as Acetex Securityholders) than the Arrangement. Acetex agreed to immediately cease, and cause its Subsidiaries, and use reasonable commercial efforts to cause Acetex's and its Subsidiaries' directors, officers, employees, financial advisers, representatives and other advisers 25 immediately to cease and cause to be terminated all existing activities, discussions and negotiations with any Persons conducted prior to the date of the Arrangement Agreement with respect to any inquiries or proposals relating to any Acquisition Proposal. Acetex agreed not to release any third party from any confidentiality agreement in respect of an Acquisition Proposal to which such third party is a party. Acetex further agreed not to release any third party from any standstill agreement to which such third party is a party, unless such third party has made a Superior Proposal and then, only in respect of such Superior Proposal. Acetex agreed to immediately request the return or destruction of all confidential information provided to any third parties who have previously entered into a confidentiality agreement in respect of an Acquisition Proposal with Acetex and shall use all reasonable efforts to ensure that such requests are honoured. Acetex agreed to notify HNA, within 48 hours of any future Acquisition Proposal of which such Acetex directors or senior officers become aware, or any amendments to the foregoing, or any request for non-public information relating to Acetex or any of Acetex's Subsidiaries in connection with an Acquisition Proposal or for access to the properties, books or records or for a list of the shareholders of Acetex or any Subsidiary by any Person that informs Acetex or such Subsidiary that it is considering making an Acquisition Proposal. Such notice shall include a copy of all written communications and a description of the material terms and conditions of any proposal and provide such details of the proposal, inquiry or contact as HNA may reasonably request, including without limitation the identity of the Person and controlling Person, if any, making such proposal, inquiry or contact. If Acetex receives a request for material non-public information from a Person who proposes a bona fide Acquisition Proposal in respect of Acetex, and the Board of Directors determines that such proposal would be a Superior Proposal in accordance with the terms of the Arrangement Agreement, then, and only in such case, the Board of Directors may, subject to the terms of the Arrangement Agreement, only provide such Person with access, in accordance with Section 6.5(a) of the Arrangement Agreement to the same information previously provided to HNA. Acetex has agreed not to accept, approve, recommend or enter into any agreement (except for a confidentiality agreement pursuant to the Arrangement Agreement) in respect of an Acquisition Proposal on the basis that it constitutes a Superior Proposal (or change or withdraw its recommendation in favour of the Arrangement) unless: (a) it has promptly provided HNA with a copy of the Acquisition Proposal document which has been determined to be a Superior Proposal; (b) five (5) Business Days (the "Notice Period") shall have elapsed from the date HNA received notice of the determination to accept, approve or recommend an agreement in respect of such Acquisition Proposal; and (c) it terminates the Arrangement Agreement pursuant to Section 10.1(e) thereof and shall have paid the termination fee discussed below to HNA. During the Notice Period, Acetex has agreed to provide a reasonable opportunity to HNA to consider, discuss and offer such adjustments in the terms and conditions of the Arrangement Agreement as would enable Acetex to proceed with its recommendation to Acetex Securityholders with respect to the Arrangement; provided however that any such adjustment shall be at the discretion of HNA at the time. Acetex has agreed that its Board of Directors will review in good faith any offer made by HNA to amend the terms of the Arrangement Agreement in order to determine, in its discretion, as part of its exercise of its fiduciary duties, whether the proposed amendments would, upon acceptance, result in such Superior Proposal ceasing to be a Superior Proposal (and whether it will change or withdraw its recommendation in favour of the Arrangement). If a majority of the Board of Directors determines that the Superior Proposal would cease to be a Superior Proposal, Acetex will so advise HNA and will accept the offer by HNA to amend the terms of the Arrangement Agreement and the parties have agreed to take such actions and execute such documents as are necessary to give effect to the foregoing. If the Board of Directors continues to believe, in good faith and after consultation with financial advisers and outside counsel, that such Superior Proposal remains a Superior Proposal and therefore rejects the amendments offered by HNA, then Acetex may, subject to the terms of the Arrangement Agreement, accept, approve, recommend or enter into an agreement, understanding or arrangement in respect of such Superior Proposal (and change or withdraw its recommendation in favour of the Arrangement). Each successive material modification of any Acquisition Proposal or a Superior Proposal shall constitute a new Acquisition Proposal for the purposes of the Arrangement Agreement and shall require a five (5) business days Notice Period from the date a copy of such amendment is provided to HNA (other than an amendment to improve upon a Superior Proposal in respect of which HNA has been provided with an opportunity to amend the terms of the Arrangement Agreement and such Superior Proposal has not ceased to be a Superior Proposal prior to the proposed amendment). In the event that Acetex provides HNA with the notice contemplated in the Arrangement Agreement on a date that is less than seven calendar days prior to the Meeting, if 26 requested by HNA, Acetex shall adjourn the Meeting to a date that is not less than seven calendar days and not more than ten calendar days after the date of such notice. See Sections 6.4, 6.5 and 6.6 of the Arrangement Agreement attached hereto as Appendix C for a more detailed description of the covenant regarding the recommendation of the Board of Directors, Acetex's non-solicitation covenants and HNA's right to match contained therein. CONDITIONS TO CLOSING CONDITIONS IN FAVOUR OF BOTH ACETEX AND HNA The Arrangement Agreement provides that the obligations of HNA and Acetex to complete the Arrangement are subject to the satisfaction or waiver, where permissible, on or before the Effective Date, of certain customary conditions, including the following: (a) the Final Order shall have been granted in form and substance satisfactory to Acetex and HNA, acting reasonably and shall not have been set aside or modified in an manner unacceptable to such parties, acting reasonably, on appeal or otherwise; (b) there shall be no action taken under any Laws or by any Governmental Entity, that: (i) makes illegal or otherwise directly or indirectly restrains, enjoins or prohibits the Arrangement or any other transactions or agreements contemplated in the Arrangement Agreement or materially modifies the Arrangement or any other transactions or agreements contemplated in the Arrangement Agreement in a manner unacceptable to the parties, acting reasonably; or (ii) results in a judgment or assessment of damages, directly or indirectly, which is material to the transactions or agreements contemplated in the Arrangement Agreement; (c) all consents, waivers, permits and approvals, including the regulatory approvals noted above, reasonably required or desirable in connection with the Arrangement and the transactions contemplated by the Arrangement Agreement shall have been obtained and/or any expiry of any statutorily defined waiting periods shall have occurred (See "INFORMATION CONCERNING THE ARRANGEMENT - Regulatory Matters"). CONDITIONS IN FAVOUR OF HNA The Arrangement Agreement provides that the obligation of HNA to complete the Arrangement is subject to the satisfaction on or before the Effective Date of a number of conditions, including the following, each of which may be waived by HNA: (a) the representations and warranties made by Acetex in the Arrangement Agreement are in the reasonable judgment of HNA true and correct in all material respects as of the Effective Date as if made on and as of such date (except to the extent such representations and warranties speak as of an earlier date or except as affected by transactions contemplated or permitted by the Arrangement Agreement or except where a representation and warranty is qualified by "in all material respects" or other similar materiality qualifiers, in which case such representation and warranty shall be true and correct) and Acetex shall have provided to HNA the certificate of a senior officer of Acetex certifying such accuracy on the Effective Date; (b) Acetex shall have complied in all material respects with its covenants under the Arrangement Agreement and Acetex shall have provided to HNA the certificate of a senior officer of Acetex certifying that Acetex has so complied with its covenants under the Arrangement Agreement; 27 (c) the Board of Directors shall have adopted all necessary resolutions, and all other necessary corporate actions shall have been taken by Acetex and its Subsidiaries to permit the consummation of the transactions contemplated by the Arrangement Agreement; (d) since the date of the Arrangement Agreement there shall have been no events, circumstances, conditions, changes or occurrences that individually, or in the aggregate, have had, or could reasonably be expected to have, a material adverse effect on the business, operations, assets, financial condition or results of operations of Acetex and any of its Subsidiaries taken as a whole, except any such effect resulting from or arising in connection with (i) the announcement of the Arrangement Agreement or the Arrangement (including any loss of customers which results from the announcement of the Arrangement Agreement), (ii) changes generally affecting the industries in which Acetex and its Subsidiaries operate that do not have a disproportionately adverse impact on Acetex and its Subsidiaries or (iii) changes in economic conditions generally that do not have a disproportionately adverse impact on Acetex and its Subsidiaries; and (e) rights of dissent shall not have been exercised, nor shall proceedings have been initiated to exercise such rights by Acetex Shareholders, Acetex Optionholders or Acetex Warrantholders which in the aggregate represent more than 10% of the outstanding capital stock of Acetex on a fully diluted basis. CONDITIONS IN FAVOUR OF ACETEX The Arrangement Agreement provides that the obligation of Acetex to complete the Arrangement is subject to the satisfaction, on or before the Effective Date, of a number of conditions, including the following, each of which may be waived by Acetex: (a) the representations and warranties made by HNA in the Arrangement Agreement are in the reasonable judgment of Acetex true and correct in all material respects as of the Effective Date as if made on and as of such date (except to the extent such representations and warranties speak as of an earlier date or except as affected by transactions contemplated or permitted by the Arrangement Agreement or except where a representation and warranty is qualified by "in all material respects" or other similar materiality qualifiers, in which case such representation and warranty shall be true and correct) and HNA shall have provided to Acetex the certificate of a senior officer of HNA certifying such accuracy on the Effective Date; and (b) HNA shall have complied in all material respects with its covenants under the Arrangement Agreement, and HNA shall have provided to Acetex the certificate of a senior officer of HNA certifying that HNA has so complied with its covenants under the Arrangement Agreement. There is no assurance that all of the conditions noted above will be satisfied or waived on a timely basis. The conditions noted above shall be conclusively deemed to have been satisfied, waived or released when with the agreement of Acetex and HNA, a certificate of arrangement in respect of the Plan of Arrangement is issued by the Registrar. TERMINATION AND PAYMENT OF FEES AND EXPENSES The Arrangement Agreement may be terminated by mutual written consent of Acetex and HNA at any time prior to the Effective Date. Either Acetex or HNA may terminate the Arrangement Agreement if: (a) the Interim Order is not granted on or before December 21, 2004 in form and substance satisfactory to HNA and Acetex, acting reasonably, or is set aside or modified in a manner unacceptable to HNA and Acetex on appeal or otherwise; (b) the Acetex Arrangement Resolutions are not passed at the Meeting on or before January 22, 2005 or such later date as may be permitted by the Arrangement Agreement, provided that Acetex may not terminate the Arrangement Agreement unless any applicable termination fee has been paid; and 28 (c) the Effective Date is not on or before August 31, 2005 or other date as the parties may mutually agree upon. HNA or Acetex may terminate the Arrangement Agreement prior to the Effective Date if any condition in the respective party's favour has not been satisfied at or prior to the date required for performance. The Arrangement Agreement may be terminated by HNA upon the entering into of a definitive agreement with respect to a Superior Proposal in accordance with the applicable provisions of the Arrangement Agreement following the failure of the Arrangement Resolutions to be passed at the Meeting, provided Acetex has paid the termination fee noted below. The Arrangement Agreement may be terminated by HNA at any time following the occurrence of a HNA Payment Event as defined below. Acetex is required to pay a termination fee to HNA in the amount of $10,000,000 if: (a) the Board of Directors withdraws, qualifies or changes any of its recommendations or determinations in support of the Arrangement in connection with Acetex entering into a definitive agreement with respect to a Superior Proposal; (b) an Acquisition Proposal is publicly announced, proposed, offered or made to the Acetex Securityholders or to Acetex, and (i) such Acquisition Proposal has not expired or been withdrawn at the time of the Meeting and (ii) the Acetex Securityholders do not approve the Arrangement Resolutions; or (c) Acetex accepts, approves, recommends or enters into any agreement with respect to an Acquisition Proposal in accordance with the applicable provisions of the Arrangement Agreement. Each of the above is referred to as an HNA Payment Event". ASSIGNMENT The Arrangement Agreement may not be assigned by either party thereto without the prior written consent of the other party thereto; provided that, notwithstanding the foregoing, Celanese may assign its rights and obligations under the Arrangement Agreement to any of its affiliates, PROVIDED that such affiliate agrees to be bound by the terms and conditions thereof and PROVIDED, FURTHER, that no such assignment shall relieve Celanese of any of its obligations thereunder. Pursuant to this provision, Celanese has assigned its rights and obligations under the Arrangement Agreement to HNA, its indirect wholly-owned Subsidiary. Celanese has not been relieved of any of its obligations under the Arrangement Agreement. HNA has the right to further assign its rights and obligations under the Arrangement Agreement to another affiliate of Celanese. SUPPORT AGREEMENTS Pursuant to the Support Agreements, each of Brooke N. Wade and Kenneth E. Vidalin irrevocably agreed: (a) to vote the Acetex Securities held or controlled by them or over which they have direction in favour of the Arrangement at the Meeting; (b) to vote the Acetex Securities held, controlled or over which they have direction against (i) any Acquisition Proposal (other than a Superior Proposal) or any action which is a component of an Acquisition Proposal (other than a component of a Superior Proposal); (ii) any reorganization, recapitalization, dissolution, liquidation or winding up of Acetex, other than one involving or consented to in writing by HNA; (iii) any action that would prevent, impede, interfere with, discourage or delay the Arrangement; (iv) any merger, 29 consolidation, business combination, sale of assets, take-over bid, amalgamation, arrangement, reorganization or recapitalization of Acetex or similar transactions or series of transactions involving Acetex (other than a Superior Proposal); (v) any sale, lease or transfer of any significant part of the assets of Acetex or similar transactions or series of transactions involving Acetex (other than a component of a Superior Proposal); (vi) any material change in the capitalization of Acetex or the corporate structure or charter of Acetex; and (vii) any action that would result in any breach of any representation, warranty or covenant of Acetex in the Arrangement Agreement; (c) not to exercise their Dissent Rights in respect of the Arrangement Resolutions; (d) not to deposit or tender, agree to deposit or tender any Acetex Securities to any take-over bid, stock exchange take-over bid or other purchase or acquisition of equity securities which is or is part of an Acquisition Proposal; (e) not to make, aid or abet, directly or indirectly, any "solicitation" of "proxies" (as such terms are used in the ABCA) in respect of any Acquisition Proposal; (f) not to initiate, propose or otherwise solicit, shareholders of Acetex for the approval of one or more shareholder proposals with respect to Acetex as described in Section 136 of the ABCA, or induce or attempt to induce any other Person to initiate any shareholder proposal with respect to Acetex, which in either case is contrary to or inconsistent with the terms of the Arrangement; and (g) not to call or seek to have called any meeting of the shareholders of Acetex, for any purpose which is contrary to or inconsistent with the terms of the Arrangement. Brooke N. Wade holds in the aggregate 7,966,846 Acetex Shares or approximately 20.74% of the issued and outstanding Acetex Securities and Kenneth E. Vidalin holds or controls 2,530,065 Acetex Shares and 781,088 Acetex Options representing 8.62% of the issued and outstanding Acetex Securities. RISK FACTORS In addition to other information contained in this Circular, Acetex Securityholders should consider the following factors in evaluating the Arrangement and deciding whether to approve the Arrangement Resolutions and risks related to continuing to hold Acetex Securities. RISK FACTORS SPECIFIC TO THE ARRANGEMENT Acetex is subject to a number of material risks if the Arrangement is not completed including those noted below. FAILURE TO COMPLETE THE ARRANGEMENT COULD HAVE A NEGATIVE IMPACT ON SHARE PRICE AND FUTURE BUSINESS OPERATIONS If the Arrangement is not completed there may be a negative impact on the Acetex Share price, future business and operations to the extent that the current trading price of the Acetex Shares reflects an assumption that the Arrangement will be completed. The price of Acetex Shares may decline if the Arrangement is not completed and such decline may be significant. COSTS AND EXPENSES OF THE ARRANGEMENT MAY NOT BE RECOVERABLE If the Arrangement is not completed, Acetex will not receive any reimbursement from HNA provided that in certain circumstances HNA shall reimburse Acetex for fifty percent (50%) of the reasonable costs actually incurred by Acetex associated with the solicitation of proxies for the approval of the Arrangement Resolutions in accordance with the Circular and the Interim Order in favour of the approval of the Arrangement Resolutions. The fees, costs and expenses of Acetex in connection with the Arrangement including, without limitation, financial advisers' fees, filing fees, legal and accounting fees, proxy solicitation fees (except as set forth above) and printing and mailing 30 costs will be payable whether or not the Arrangement is completed are anticipated to be approximately U.S.$10M. In addition, Acetex may, as set out in this Circular, be required to make certain termination payments to HNA. THERE MAY BE NOT BE ANOTHER ATTRACTIVE TAKEOVER MERGER OR BUSINESS COMBINATION If the Arrangement is not completed and the Board of Directors of Acetex decides to seek another merger or business combination, there can be no assurance that it will be able to find a purchaser willing to pay an equivalent or more attractive price than the price to be paid by HNA under the Arrangement. ACETEX MAY BE REQUIRED TO PAY A TERMINATION FEE In the event the Arrangement Agreement is terminated, Acetex may in certain circumstances be obligated to pay a termination fee to HNA in the amount of $10,000,000. See "THE ARRANGEMENT AGREEMENT - Termination and Payment of Fees and Expenses. The termination fee may discourage other parties from participating in a transaction with Acetex, even if those parties might be willing to offer greater value to Acetex Securityholders than HNA has offered. RISK FACTORS RELATED TO ACETEX If the Arrangement is not completed, Acetex will continue to face all of the existing operational and financial risks of its businesses which are described in Acetex's annual information form dated March 29, 2004 and which are hereby incorporated by reference into this Circular. CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS In the opinion of Burnet, Duckworth & Palmer LLP, counsel to Acetex, the following is a summary of the principal Canadian federal income tax considerations generally applicable to the disposition of Acetex Securities pursuant to the Arrangement by Acetex Securityholders who, for purposes of the Tax Act and at all relevant times, deal at arm's length, and are not affiliated, with Acetex or HNA. This summary is generally applicable to an Acetex Shareholder or Acetex Warrantholder who, for purposes of the Tax Act and at all relevant times, holds Acetex Shares or Acetex Warrants as capital property. Acetex Shares or Acetex Warrants will generally constitute capital property to a holder thereof unless the holder holds such shares or warrants in the course of carrying on a business or has acquired such shares or warrants in a transaction or transactions considered to be an adventure or concern in the nature of trade. An Acetex Shareholder that is a resident of Canada and whose shares might not otherwise qualify as capital property may be eligible to make an irrevocable election in accordance with subsection 39(4) of the Tax Act to have the Acetex Shares and every "Canadian security" (as defined in the Tax Act) owned by such holder in the taxation year of the election and in all subsequent taxation years deemed to be capital property. Acetex Shareholders considering making such election should consult with their own tax advisers. This summary is applicable to Acetex Optionholders who have acquired or are deemed to have acquired their Acetex Options in respect of, in the course of or by virtue of employment (including being an officer or director) with Acetex or a Subsidiary thereof. This summary does not apply to Acetex Securityholders that are "specified financial institutions" or "financial institutions" or to an Acetex Securityholder, an interest in which would be a "tax shelter investment" (all as defined in the Tax Act). This summary does not address any Canadian federal income tax consequences generally applicable to Holdco Shareholders. All such holders should consult their own tax advisers. This summary is based upon the current provisions of the Tax Act and the regulations thereunder, and counsel's understanding of the administrative and assessing practices of the CRA published in writing prior to the date hereof. This summary also takes into account all specific proposals to amend the Tax Act and the regulations thereunder publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the "Tax Proposals") and assumes that the Tax Proposals will be enacted substantially as proposed, although there is no 31 certainty that the Tax Proposals will be so enacted, if at all. This summary is not exhaustive of all possible Canadian federal income tax considerations and, except for the Tax Proposals, does not take into account or anticipate any changes in Law or CRA administrative and assessing practices, whether by legislative, regulatory, administrative, governmental or judicial decision or action, nor does it take into account or consider other federal or any provincial, territorial or foreign tax considerations, which may differ from the Canadian federal income tax considerations described herein. THIS SUMMARY IS OF A GENERAL NATURE ONLY AND IS NOT INTENDED TO BE, NOR SHOULD IT BE CONSTRUED TO BE, LEGAL OR TAX ADVICE TO ANY PARTICULAR ACETEX SECURITYHOLDER. THIS SUMMARY IS NOT EXHAUSTIVE OF ALL CANADIAN FEDERAL INCOME TAX CONSIDERATIONS. CONSEQUENTLY, ACETEX SECURITYHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISERS FOR ADVICE AS TO THE TAX CONSIDERATIONS IN RESPECT OF THE ARRANGEMENT HAVING REGARD TO THEIR PARTICULAR CIRCUMSTANCES. RESIDENTS OF CANADA This part of the summary is generally applicable to an Acetex Securityholder who, for purposes of the Tax Act and any applicable income tax convention, and at all relevant times, is a resident or deemed to be a resident of Canada. Such a resident Acetex Shareholder or Acetex Warrantholder whose Acetex Shares or Acetex Warrants are disposed of to HNA under the Arrangement will generally realize a capital gain (or a capital loss) to the extent the proceeds of disposition of such shares or warrants are greater (or less) than the total of the holder's adjusted cost base of such shares or warrants and any reasonable costs of disposition. Generally, one-half of any capital gain realized by an Acetex Shareholder or Acetex Warrantholder (a "taxable capital gain") will be required to be included in income in the taxation year in which it is realized, and one-half of any capital loss realized by such holder (an "allowable capital loss") will be deductible, subject to certain limitations, from taxable capital gains in the year of disposition. Allowable capital losses in excess of taxable capital gains in a particular year may be deducted against net taxable capital gains realized in any of the three preceding years or any subsequent year, to the extent and under the circumstances permitted in the Tax Act. An Acetex Shareholder or Acetex Warrantholder that is throughout the year a "Canadian-controlled private corporation" (as defined in the Tax Act) may be subject to an additional refundable tax of 6 2/3% on certain investment income, including taxable capital gains. Capital gains realized by an individual or trust, other than certain trusts, may give rise to alternative minimum tax under the Tax Act. If an Acetex Shareholder is a corporation, any capital loss realized by the holder on the disposition of Acetex Shares may in certain circumstances be reduced by the amount of any dividends which have been received (or deemed to be received) on such shares to the extent and under the circumstances prescribed by the Tax Act. Analogous rules apply to a partnership or trust of which a corporation, trust or partnership is a member or beneficiary. An Acetex Optionholder whose options are acquired by HNA under the Arrangement will be deemed to have received an employment benefit equal to the amount of the consideration received from HNA, will generally be required to include such amount in income and may be entitled to deduct one half of such amount in computing his or her taxable income. Acetex Optionholders should consult their advisers with respect to their entitlement to such deduction. A Dissenting Shareholder who is ultimately entitled to receive the fair value of Acetex Shares held by such holder will generally be considered to have disposed of the Acetex Shares and will (i) be deemed to have received a dividend in the amount by which the amount so received (less any interest awarded by the Court) exceeds the paid up capital of the Acetex Shares so disposed of and (ii) realize a capital gain or capital loss equal to the amount by which the amount received (less interest and, except to the extent subsection 55(2) of the Tax Act applies, the amount of any deemed dividend described in (i) above) exceeds or is less than the adjusted cost base of such shares. Any interest received will be included in the dissenter's income for the purposes of the Tax Act. Acetex has advised counsel that the paid up capital of each Acetex Share is estimated 32 to be approximately $4.27 as of the date of this Circular. Any amount which is deemed to be a dividend and is deemed to be received by an Acetex Shareholder that is a corporation resident in Canada may be deemed by subsection 55(2) of the Tax Act to be a capital gain and such shareholders should consult their own advisers with respect to such treatment and the discussion above with respect to computation of capital gains and capital losses. A Dissenting Warrantholder who is ultimately entitled to be paid the fair value of such holder's warrants will be considered to have disposed of the Acetex Warrants for proceeds of disposition equal to the amount received less any interest awarded by the Court. Any interest received will be included in the dissenter's income for the purposes of the Tax Act. The discussion above in respect of Acetex Optionholders whose options are acquired by HNA under the Arrangement is generally applicable to a Dissenting Optionholder who is ultimately entitled to be paid the fair value of such holder's options. Such payments made to Dissenting Optionholders will be subject to normal withholding taxes and payroll charges. Any interest received will be included in the dissenter's income for the purposes of the Tax Act. NON-RESIDENTS OF CANADA This part of the summary is generally applicable to an Acetex Shareholder, Acetex Warrantholder or Acetex Optionholder who, for purposes of the Tax Act and any applicable income tax convention, and at all relevant times, is not and has not been a resident or deemed to be a resident of Canada and whose Acetex Securities are not taxable Canadian property for the purposes of the Tax Act at the time of disposition. Special rules, which are not discussed in this summary, may apply to a non-resident that is an insurer carrying on business in Canada and elsewhere. This summary assumes that the Acetex Shares will be listed on the TSX at all relevant times. Generally, Acetex Shares, Acetex Warrants or Acetex Options will not be taxable Canadian property to an Acetex Shareholder, Acetex Warrantholder or Acetex Optionholder at a particular time provided that (i) the Acetex Shares are listed on a prescribed stock exchange (which currently includes the TSX) at that time, (ii) the Acetex Shareholder, Acetex Warrantholder or Acetex Optionholder does not use or hold, and is not deemed to use or hold, such shares, warrants or options in carrying on a business in Canada, (iii) the Acetex Shareholder, Acetex Warrantholder or Acetex Optionholder, Persons with whom such holder did not deal at arm's length, or such holder together with such Persons, did not own 25% or more of the issued shares of any class or series in the capital of Acetex at any time during the 60 month period that ends at that time, and (iv) such Acetex Shares, Acetex Warrants or Acetex Options are not otherwise deemed to be taxable Canadian property. Such a non-resident Acetex Shareholder or Acetex Warrantholder will not be subject to tax under the Tax Act on any capital gain, or entitled to deduct any capital loss, realized on the disposition of Acetex Shares or Acetex Warrants to HNA under the Arrangement. To the extent an Acetex Option was granted in respect of services performed in Canada, any amount received by the non-resident Acetex Optionholder on the transfer of such Acetex Option to HNA will generally be required to be included in income and such holder may be entitled to deduct one half of such amount in computing his or her taxable income. Acetex Optionholders should consult their advisers with respect to the Canadian federal income tax considerations applicable in respect of Acetex Options. Otherwise, an Acetex Optionholder will not be subject to tax under the Tax Act on any capital gain, or entitled to deduct any capital loss, realized on the disposition of Acetex Options to HNA under the Arrangement. A non-resident Dissenting Shareholder who is ultimately entitled to receive the fair value of such holder's shares will be considered to have disposed of the Acetex Shares to Acetex and will generally be deemed to have received a dividend equal to the amount received less the paid up capital of such shares and less any interest awarded by the Court. Such deemed dividend and any interest received will be subject to Canadian withholding tax at the rate of 25%, subject to reduction by any applicable income tax convention. Acetex has advised counsel that the paid up capital of each Acetex Share is estimated to be approximately $4.27 as of the date of this Circular. 33 A non-resident Dissenting Warrantholder who is ultimately entitled to be paid the fair value of such holder's warrants will generally not be subject to tax under the Tax Act on any capital gain, or entitled to deduct any capital loss, realized on the disposition of Acetex Warrants to Acetex. Any interest received will be subject to Canadian withholding tax at the rate of 25%, subject to reduction by any applicable income tax convention. The discussion above in respect of non-resident Acetex Optionholders whose options are acquired by HNA under the Arrangement is generally applicable to a non-resident Dissenting Optionholder who is ultimately entitled to be paid the fair value of such holder's options. Acetex Securityholders subject to tax in other jurisdictions are urged to consult with their own tax advisers in those jurisdictions for advice as to tax considerations in respect of the Arrangement having regard to their own particular circumstances. DISSENTING SECURITYHOLDER RIGHTS THE FOLLOWING DESCRIPTION OF THE RIGHT TO DISSENT AND APPRAISAL TO WHICH REGISTERED DISSENTING SECURITYHOLDERS ("DISSENTING SECURITYHOLDERS") ARE ENTITLED IS NOT A COMPREHENSIVE STATEMENT OF THE PROCEDURES TO BE FOLLOWED BY A DISSENTING SECURITYHOLDER WHO SEEKS PAYMENT OF THE FAIR VALUE OF SUCH DISSENTING SECURITYHOLDER'S ACETEX SECURITIES AND IS QUALIFIED IN ITS ENTIRETY BY THE REFERENCE TO THE FULL TEXT OF THE INTERIM ORDER AND SECTION 191 OF THE ABCA WHICH ARE ATTACHED TO THIS CIRCULAR AS APPENDICES B AND E. A REGISTERED DISSENTING SECURITYHOLDER WHO INTENDS TO EXERCISE THE RIGHT TO DISSENT AND APPRAISAL SHOULD CAREFULLY CONSIDER AND COMPLY WITH THE PROVISIONS OF SECTION 191 OF THE ABCA AS MODIFIED BY THE INTERIM ORDER. FAILURE TO STRICTLY COMPLY WITH THE PROVISIONS OF THAT SECTION AND TO ADHERE TO THE PROCEDURES ESTABLISHED THEREIN MAY RESULT IN THE LOSS OF ALL RIGHTS THEREUNDER. The Court hearing the application for the Final Order has the discretion to alter the rights of dissent described herein based on the evidence presented at such hearing. Pursuant to the Interim Order, registered Acetex Securityholders are entitled, in addition to any other right such holder may have, to dissent and to be paid by Acetex, in the event the Arrangement becomes effective the fair value of the Acetex Securities held by such holder in respect of which such holder dissents, determined as of the close of business on the last Business Day before the day on which the Arrangement is approved by Acetex Securityholders at the Meeting. A registered Acetex Securityholder may dissent only with respect to all of the Acetex Securities held by such holder or on behalf of any one beneficial owner and registered in the Dissenting Securityholder's name. ONLY REGISTERED ACETEX SECURITYHOLDERS MAY DISSENT. PERSONS WHO ARE BENEFICIAL OWNERS OF ACETEX SECURITIES REGISTERED IN THE NAME OF A BROKER, CUSTODIAN, NOMINEE OR OTHER INTERMEDIARY WHO WISH TO DISSENT, SHOULD BE AWARE THAT THEY MAY ONLY DO SO THROUGH THE REGISTERED OWNER OF SUCH SECURITIES. A REGISTERED HOLDER, SUCH AS A BROKER, WHO HOLDS ACETEX SECURITIES AS NOMINEE FOR BENEFICIAL HOLDERS, SOME OF WHOM WISH TO DISSENT, MUST EXERCISE DISSENT RIGHTS ON BEHALF OF SUCH BENEFICIAL OWNERS WITH RESPECT TO THE ACETEX SECURITIES HELD FOR SUCH BENEFICIAL OWNERS. IN SUCH CASE, THE DEMAND FOR DISSENT SHOULD SET FORTH THE NUMBER OF ACETEX SECURITIES COVERED BY IT. ALTERNATIVELY, SUCH A AN ACETEX SECURITYHOLDER MAY WISH TO INSTRUCT THE INTERMEDIARY TO CAUSE SUCH ACETEX SECURITIES TO REGISTERED IN THE HOLDER'S NAME SO THAT THE HOLDER MAY EXERCISE RIGHTS OF DISSENT DIRECTLY. A Dissenting Securityholder must send a written objection to the Arrangement Resolutions, which written objection must be received by Acetex at its registered office, c/o Burnet, Duckworth & Palmer LLP, Suite 1400, 350 - 7th Ave. S.W., Calgary, Alberta T2P 3N9 by 5:00 p.m. (Calgary time) on the Business Day immediately preceding the date of the Meeting. A registered Acetex Securityholder wishing to exercise the right to dissent with respect to such holder's Acetex Securities shall not vote such Acetex Securities at the Meeting, either by the submission of a proxy or by voting in person, in favour of the Arrangement Resolutions. An application may be made to the Court of Queen's Bench of Alberta by Acetex or by a Dissenting Securityholder after the adoption of the Arrangement Resolutions to fix the fair value of the Dissenting Securityholder's Acetex 34 Securities. If such an application to the Court is made by Acetex or a Dissenting Acetex Securityholder, Acetex must, unless the Court otherwise orders, send to each Dissenting Securityholder a written offer to pay the Dissenting Securityholder an amount considered by the Acetex Board of Directors to be the fair value of the Acetex Securities, as applicable. The offer, unless the Court otherwise orders, will be sent to each Dissenting Securityholder at least 10 days before the date on which the application is returnable, if Acetex is the applicant, or within 10 days after Acetex is served with notice of the application, if a Dissenting Securityholder is the applicant. The offer will be made on the same terms to each Dissenting Securityholder of Acetex Securities, as applicable, and will be accompanied by a statement showing how the fair value was determined. A Dissenting Securityholder may make an agreement with Acetex for the purchase of such holder's Acetex Securities in the amount of the offer made by Acetex (or otherwise) at any time before the Court pronounces an order fixing the fair value of the Acetex Securities. A Dissenting Securityholder is not required to give security for costs in respect of an application and, except in special circumstances, will not be required to pay the costs of the application or appraisal. On the application, the Court will make an order fixing the fair value of the Acetex Securities, as applicable, of all Dissenting Securityholders who are parties to the application, giving judgment in that amount against Acetex and in favour of each of those Dissenting Securityholders, and fixing the time within which Acetex must pay that amount payable to the Dissenting Securityholders. The Court may in its discretion allow a reasonable rate of interest on the amount payable to each Dissenting Securityholder calculated from the date on which the Dissenting Securityholder ceases to have any rights as an Acetex Securityholder, until the date of payment. On the Arrangement becoming effective, or upon the making of an agreement between Acetex and the Dissenting Securityholder as to the payment to be made by Acetex to the Dissenting Securityholder, or upon the pronouncement of a Court order, whichever first occurs, the Dissenting Securityholder will cease to have any rights as an Acetex Securityholder other than the right to be paid the fair value of such holder's Acetex Securities, in the amount agreed to between Acetex and the Dissenting Securityholder or in the amount of the judgment, as the case may be. Until one of these events occurs, the Dissenting Securityholder may withdraw the Dissenting Securityholder's dissent, or if the Arrangement has not yet become effective, Acetex may rescind the Arrangement Resolutions, and in either event the dissent and appraisal proceedings in respect of that Dissenting Securityholder will be discontinued. Acetex shall not make a payment to a Dissenting Securityholder if there are reasonable grounds for believing that Acetex is or would after the payment be unable to pay its liabilities as they become due, or that the realizable value of the assets of Acetex would thereby be less than the aggregate of its liabilities. In such event, Acetex shall notify each Dissenting Securityholder that it is unable lawfully to pay Dissenting Securityholders for their securities, as applicable, in which case the Dissenting Securityholder may, by written notice to Acetex within 30 days after receipt of such notice, withdraw such holder's written objection, in which case Acetex shall be deemed to consent to the withdrawal and such Dissenting Securityholder shall be reinstated with full rights as a Securityholder, failing which such Dissenting Securityholder retains its status as a claimant against Acetex to be paid as soon as Acetex is lawfully entitled to do so or, in a liquidation, to be ranked subordinate to the rights of creditors of Acetex but in priority to its shareholders. All Acetex Securities held by Dissenting Securityholders who exercise their right to dissent will, if the holders are ultimately entitled to be paid the fair value thereof, be deemed to be transferred to Acetex and cancelled in exchange for such fair value. The above summary does not purport to provide a comprehensive statement of the procedures to be followed by a Dissenting Securityholder who seeks payment of the fair value of their Acetex Securities. The Interim Order and Section 191 of the ABCA requires adherence to the procedures established therein and failure to do so may result in the loss of all rights thereunder. ACCORDINGLY, EACH DISSENTING SECURITYHOLDER WHO MIGHT DESIRE TO EXERCISE THE RIGHT TO DISSENT AND APPRAISAL SHOULD CAREFULLY CONSIDER AND COMPLY WITH THE PROVISIONS OF THE INTERIM ORDER, A COPY OF WHICH IS ATTACHED AS APPENDIX B TO THIS CIRCULAR TOGETHER WITH SECTION 191 OF THE ABCA, THE FULL TEXT OF WHICH IS SET OUT IN APPENDIX E TO THIS CIRCULAR AND SHOULD CONSULT THEIR OWN LEGAL ADVISER. 35 It is a condition to the obligation of HNA to complete the Arrangement that rights of dissent shall not have been exercised, nor shall proceedings have been initiated to exercise such rights by Acetex Shareholders, Acetex Optionholders or Acetex Warrantholders which in the aggregate represent more than 10% of the outstanding capital stock of Acetex on a fully diluted basis. INFORMATION ABOUT HNA HNA, is an indirect wholly-owned subsidiary of Celanese. Celanese, through its Subsidiaries, is an integrated global producer of value-added industrial chemicals. The operations of Celanese and its Subsidiaries are located in North America, Europe and Asia, including substantial joint ventures in China.

Celanese and Acetex were the original signatories to the Arrangement Agreement. Celanese assigned its rights and obligations under the Arrangement Agreement to HNA, its indirect wholly-owned Subsidiary. HNA intends to fund the Arrangement through a refinancing and increase of the existing senior credit facility of its indirect parent, BCP Crystal US Holdings Corp.

COMPOSITION OF COMPENSATION COMMITTEE Acetex's compensation committee, which is entitled as the Human Resources and Corporate Governance Committee is comprised of John L. Garcia, John B. Zaozirny, Q.C., and Pierre Dutheil, none of whom are or have ever been officers or employees of Acetex or any of its Subsidiaries. Mr. Dutheil is indebted to the Corporation as discussed below under the heading "Indebtedness of Directors and Executive Officers". REPORT ON EXECUTIVE COMPENSATION BY THE COMPENSATION COMMITTEE Acetex's compensation policies are designed to take into account the circumstances surrounding the initial formation of Acetex and generally to reward executive officers for long term strategic management which results in the enhancement of shareholder value. Accordingly, Mr. Wade, being the largest shareholder of Acetex, was not awarded any stock options and is paid a base salary which the Committee believes to be reasonable given Mr. Wade's responsibilities, position and experience. Mr. Vidalin was previously awarded significant stock options in order that Mr. Vidalin's compensation would be commensurate with appreciation in shareholder value and in order to ensure that Mr. Vidalin was a significant equity holder in Acetex. Mr. Vidalin's salary is also believed by the Committee to be reasonable given Mr. Vidalin's responsibilities, position and experience. Ms. Bondar is currently paid a salary the Committee believes to be fair given Ms. Bondar's responsibilities, position and experience. The Compensation Committee awarded bonuses to Mr. Wade, Mr. Vidalin and Mr. Miller in respect of the 2003 fiscal year. Submitted on behalf of the Compensation Committee by: ~~John L.

(b) Acetex shall immediately cease, and shall cause its Subsidiaries, and shall use reasonable commercial efforts to cause Acetex's and its Subsidiaries' directors, officers, employees, financial advisors, representatives and other advisors immediately to cease and cause to be terminated all existing activities, discussions and negotiations with any Persons conducted prior to the date hereof with respect to any inquiries or proposals relating to any Acquisition Proposal. Acetex agrees not to release any third party from any confidentiality agreement in respect of an Acquisition Proposal to which such third party is a party. Acetex further agrees not to release any third party from any standstill agreement to which such third party is a party, unless such third party has made a Superior Proposal and then, only in respect of such Superior Proposal. Acetex shall immediately request the return or destruction of all confidential information provided to any third parties who have previously entered into a confidentiality agreement in respect of an Acquisition Proposal with Acetex and shall use all reasonable efforts to ensure that such requests are honoured. (c) Acetex shall forthwith notify AcquisitionCo (orally and in writing), within 48 hours of any future Acquisition Proposal of which such Acetex directors or senior officers become aware, or any amendments to the foregoing, or any request for non-public information relating to Acetex or any of Acetex's Subsidiaries in connection with an Acquisition Proposal or for access to the properties, books or records or for a list of the shareholders of Acetex or any Subsidiary by any Person that informs Acetex or such Subsidiary that it is considering making an Acquisition Proposal. Such notice shall include a copy of all written communications and a description of the material terms and conditions of any proposal and provide such details of the proposal, inquiry or contact as AcquisitionCo may reasonably request, including without limitation the identity of the Person and controlling Person, if any, making such proposal, inquiry or contact. (d) If Acetex receives a request for material non-public information from a Person who proposes a BONA FIDE Acquisition Proposal in respect of Acetex, and the Board of Directors of Acetex determines that such proposal would be a Superior Proposal pursuant to Section 7.5(a), assuming the satisfactory outcome of a due diligence condition which conforms to Section 7.5(a)(ii), then, and only in such case, the Board of Directors of Acetex may, subject to the execution of a confidentiality agreement substantially similar to the Confidentiality Agreement (PROVIDED, HOWEVER, the Person making the Acquisition Proposal shall not be precluded thereunder from making the Acquisition Proposal as proposed) and provided Acetex sends a copy of any such confidentiality agreement to AcquisitionCo immediately upon its execution, only provide such Person with access, in accordance with Section 7.5(a) to the same information previously provided C-17 to AcquisitionCo. Acetex shall provide AcquisitionCo with a list of the information provided to the Person making the Superior Proposal. (e) Acetex shall ensure that its Subsidiaries and its and its Subsidiaries' respective directors, officers, employees, financial advisors and other advisors or representatives are aware of the provisions of this Section 7.5, and it shall be responsible for any breach of this Section 7.5 by its or its Subsidiaries' directors, officers, employees, financial advisors or other advisors or representatives. 7.6 NOTICE OF SUPERIOR PROPOSAL DETERMINATION Acetex shall not accept, approve or recommend or enter into any agreement (except for a confidentiality agreement pursuant to Section 7.5(d)) in respect of an Acquisition Proposal on the basis that it constitutes a Superior Proposal (or change or withdraw its recommendation in favour of the Arrangement) unless: (a) it has promptly provided AcquisitionCo with a copy of the Acquisition Proposal document which has been determined to be a Superior Proposal; (b) five (5) business days (the "Notice Period") shall have elapsed from the date AcquisitionCo received notice of the determination to accept, approve or recommend an agreement in respect of such Acquisition Proposal; and (c) before entering into any agreement (except for a confidentiality agreement pursuant to Section 6.5(d)) with respect to a Superior Proposal, this Agreement shall have been terminated pursuant to Section 10.1(e). During the Notice Period, Acetex shall provide a reasonable opportunity to AcquisitionCo to consider, discuss and offer such adjustments in the terms and conditions of this Agreement as would enable Acetex to proceed with its recommendation to Acetex Securityholders with respect to the Arrangement; PROVIDED, HOWEVER, that any such adjustment shall be at the discretion of AcquisitionCo at the time. The Board of Directors of Acetex will review in good faith any offer made by AcquisitionCo to amend the terms of this Agreement in order to determine, in its discretion, as part of its exercising its fiduciary duties, whether the proposed amendments would, upon acceptance, result in such Superior Proposal ceasing to be a Superior Proposal (and whether it will change or withdraw its recommendation in favour of the Arrangement). If a majority of the Board of Directors of Acetex determines that the Superior Proposal would cease to be a Superior Proposal, Acetex will so advise AcquisitionCo and will accept the offer by AcquisitionCo to amend the terms of this Agreement and the Parties agree to take such actions and execute such documents as are necessary to give effect to the foregoing. If the Board of Directors of Acetex continues to believe, in good faith and after consultation with financial advisors and outside counsel, that such Superior Proposal remains a Superior Proposal and therefore rejects the amendments offered by AcquisitionCo, then Acetex may, subject to the terms of this Agreement, accept, approve, recommend or enter into an agreement, understanding or arrangement in respect of such Superior Proposal (and change or withdraw its recommendation in favour of the Arrangement). Each successive material modification of any Acquisition Proposal or a Superior Proposal shall constitute a new Acquisition Proposal for the purposes of this Section 7.6 and shall require a five (5) business days Notice Period from the date a copy of such amendment is provided to AcquisitionCo (other than an amendment to improve upon a Superior Proposal in respect of which AcquisitionCo has been provided with an opportunity to amend the terms of this Agreement and such Superior Proposal has not ceased to be a Superior Proposal prior to the proposed amendment). In the event that Acetex provides AcquisitionCo with the notice contemplated in this Section on a date that is less than seven calendar days prior to the Acetex Meeting, if requested by AcquisitionCo, Acetex shall adjourn the Acetex Meeting to a date that is not less than seven calendar days and not more than ten calendar days after the date of such notice. Information provided hereunder shall constitute confidential information under the Confidentiality Agreement. 7.7 ACCESS Subject to the Confidentiality Agreement and applicable Laws, for the period between the execution of this Agreement and the Effective Date, (a) Acetex shall (and shall cause its Subsidiaries to) permit, subject to appropriate confidentiality restrictions, representatives of AcquisitionCo and financing sources to have reasonable access during normal business hours and upon reasonable prior notice and for reasonable business purposes, and in a manner so as not to interfere with the normal business operations of Acetex and its Subsidiaries, to all premises, properties, personnel, books, records (including Tax records), Contracts, and documents of or pertaining to each of Acetex and its Subsidiaries and (b) Acetex shall (and shall cause its Subsidiaries to) furnish promptly to AcquisitionCo any new material information concerning its business, properties and personnel that comes into existence after the execution of this Agreement. C-18 7.8 ACETEX'S COVENANTS RE MEETING Notwithstanding anything herein to the contrary, the Arrangement shall be submitted to a vote of the Acetex Securityholders at the Acetex Meeting for the purpose of adopting the Arrangement and nothing contained herein shall be deemed to relieve Acetex of such obligation. Acetex covenants and agrees that, except as contemplated in this Agreement or pursuant to the Arrangement, until the Effective Time or the day upon which this Agreement is terminated, whichever is earlier, it will: (a) as soon as reasonably practicable after the date hereof, but in any event no later than December 17, 2004 (or such other date as the parties may agree upon), file, proceed with and diligently prosecute an application to the Court for the Interim Order with respect to the Arrangement, PROVIDED that notwithstanding the foregoing, the Parties agree to consult and obtain each other's approval regarding seeking the Interim Order and mailing the Acetex Circular; (b) in a timely and expeditious manner: (i) forthwith carry out the terms of the Interim Order; (ii) prepare and complete, in conjunction with AcquisitionCo, the Acetex Circular together with any other documents required by the Securities Act (Alberta) and other applicable Laws in connection with the Acetex Meeting and the Arrangement. Acetex shall cause the Acetex Circular and other documentation required in connection with the Acetex Meeting to be filed in all jurisdictions where the same is required to be filed and mail the same as ordered by the Interim Order and in accordance with all applicable Laws, in all jurisdictions where the same is required, complying in all material respects with all applicable Laws on the date of mailing thereof and containing full, true and plain disclosure of all material facts relating to the Arrangement and Acetex and not containing any misrepresentation, as defined under such applicable Laws, with respect thereto. Acetex shall permit AcquisitionCo to review and comment on drafts of the Acetex Circular including any amendments or supplements thereto and other documentation and shall not file or amend such document without the permission of AcquisitionCo (not to be unreasonably withheld); (iii) promptly notify AcquisitionCo if, at any time before the Effective Date, it becomes aware that the Acetex Circular contains any untrue statement of a material fact or omits to state a material fact required to be stated therein or which is necessary to make the statements contained therein not misleading in light of the circumstances in which they are made, or that otherwise requires an amendment or supplement to the Acetex Circular. In any such event, Acetex shall cooperate in the preparation of a supplement or amendment to the Acetex Circular and, if required, shall cause the same to be distributed to shareholders of Acetex and/or filed with the relevant Governmental Entities; (iv) ensure that the Acetex Circular complies with all applicable Laws. Without limiting the generality of the foregoing, Acetex shall ensure that the Acetex Circular provides Acetex Securityholders with information in sufficient detail to permit them to form a reasoned judgment concerning the matters to be placed before them at the Acetex Meeting; (v) solicit proxies for the approval of the Acetex Arrangement Resolutions in accordance with the Acetex Circular and the Interim Order in favour of the approval of the Acetex Arrangement Resolutions, including, if so requested by AcquisitionCo using the services of dealers and proxy solicitation services (the costs of which shall be borne by Acetex; PROVIDED, that if this Agreement is terminated pursuant to Section 10.1(a), Section 10.1(b) (but not in the event of a termination as provided in Section 7.2) or Section 10.1(c) C-19 (unless there shall have occurred an AcquisitionCo Payment Event at such time), AcquisitionCo shall reimburse Acetex for fifty percent (50%) of the reasonable costs associated therewith) and take all other action that is necessary or desirable to secure the approval of the Arrangement by the Acetex Securityholders; (vi) convene the Acetex Meeting and distribute copies of this Agreement (or a written summary thereof prepared by Acetex in form and substance satisfactory to AcquisitionCo acting reasonably), in each case as ordered by the Interim Order; and (vii) conduct the Acetex Meeting in accordance with the Interim Order, the by-laws of Acetex and any instrument governing such meeting, as applicable, and as otherwise required by applicable Laws; (c) in a prompt and expeditious manner, prepare, only after obtaining the approval of AcquisitionCo (not to be unreasonably withheld), and file any mutually agreed (or otherwise required by applicable Laws) amendments or supplements to the Acetex Circular with respect to the Acetex Meeting and mail the same as required by the Interim Order and in accordance with all applicable Laws, in all jurisdictions where the same is required, complying in all material respects with all applicable legal requirements on the date of mailing thereof; (d) convene and hold the Acetex Meeting as soon as practicable after the date hereof, but in any case, before January 22, 2005 (or such later date as may be requested by AcquisitionCo pursuant to the penultimate sentence of Section 6.6) (the date of the meeting being the "Acetex Meeting Date") for the purpose of considering the Acetex Arrangement Resolutions, and with the written consent of AcquisitionCo for any other proper purpose as may be set out in the notice for such meeting; (e) subject to the approval of the Arrangement at the Acetex Meeting, in accordance with the provisions of the Interim Order, and subject to Article 8, forthwith proceed with and diligently prosecute an application for the Final Order; (f) forthwith carry out the terms of the Final Order (to the extent within its power) and, subject to the receipt of the Final Order, the satisfaction of the conditions precedent in favour of Acetex and the receipt of the written confirmation of AcquisitionCo that the conditions precedent in favour of AcquisitionCo have been satisfied, file Articles of Arrangement and the Final Order with the Registrar in order for the Arrangement to become effective; (g) except for individual proxies and other non-substantive communications, furnish promptly to AcquisitionCo a copy of each notice, report, report of proxies submitted, schedule or other document or communication delivered, filed or received by Acetex in connection with the Arrangement or the Interim Order, the Acetex Meeting or any other meeting of Acetex Securityholders or class of security holders which all such holders, as the case may be, are entitled to attend, any filings under applicable Laws and any dealings with regulatory agencies in connection with, or in any way affecting, the transactions contemplated hereby; (h) furnish promptly to AcquisitionCo a list of all securityholders that have provided a Notice of Dissent with respect to the Arrangement in accordance with the Interim Order; and (i) subject to Section 7.7, in a timely and expeditious manner, provide to AcquisitionCo all information, as may be reasonably requested by AcquisitionCo or as required by the Interim Order or applicable Laws, with respect to Acetex and its Subsidiaries and their respective businesses and properties. C-20 7.9 INDEMNIFICATION OF DIRECTORS AND OFFICERS, CORPORATE INDEMNITIES AND INSURANCE (a) AcquisitionCo shall (i) maintain in effect the current or substantially similar provisions regarding indemnification of officers and directors contained in any directors', officers' or employees' indemnification agreements of Acetex or its Subsidiaries; (ii) maintain in effect, for a period of six (6) years after the Effective Date, Acetex's current or substantially similar directors' and officers' liability insurance and fiduciary liability insurance PROVIDED that such insurance shall have a coverage limit of no less than 110% of the current limits of such insurance within (3) months of the Effective Time; and (iii) pay premiums in respect of such insurance at a rate of up to 250% of the current annual premiums for such insurance (PROVIDED that AcquisitionCo may substitute therefor policies of at least the same coverage and amounts containing terms and conditions which are, in the aggregate, not materially less advantageous to the insured) with respect to claims arising from facts or events which occurred on or before the Effective Date. Alternatively, at AcquisitionCo's option, it may cause Acetex to purchase "run-off" directors' and officers' liability insurance providing coverage substantially as favourable to such directors and officers as that in effect under such current policies to cover prior events during such six year period or the balance thereof. (b) The provisions of this Section 7.9 are (i) for the benefit of, and shall be enforceable by, each indemnified party, his heirs, executors, administrators and other legal representatives; and (ii) in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have by Contract or otherwise, and such rights shall be held by AcquisitionCo in trust for such Person; PROVIDED, HOWEVER, that no approval of any beneficiary of such trust shall be required in connection with an amendment or variation of this Section 7.9 prior to the Effective Date. 7.10 ACQUISITIONCO'S COVENANTS (a) AcquisitionCo covenants and agrees to carry out the terms of the Interim Order and Final Order as applicable to it and, except as contemplated in this Agreement or pursuant to the Arrangement, until the Effective Time or the day upon which this Agreement is terminated, whichever is earlier: (i) AcquisitionCo will deposit with the Depositary all funds required to be paid by it pursuant to the Plan of Arrangement no later than twenty-four (24) hours before the Effective Date by way of a bank draft, wire transfer or other form of immediately available funds; (ii) AcquisitionCo will provide information and consulting to Acetex during the development of the Saudi Project for the purpose of permitting and facilitating implementation of the Saudi Project with AcquisitionCo technology after completion of the Arrangement; and (iii) AcquisitionCo shall not, and shall not permit any of its Subsidiaries to, in any manner whatsoever, without the prior written consent of Acetex, hold any discussions with any Person with respect to the construction, operation and ownership of a methanol plant, acetic acid plant or vinyl acetate monomer plant in the Kingdom of Saudi Arabia (a "Project"), other than the proposed partners of Acetex identified in the Disclosure Letter (the "Saudi Partners"). (b) In the event this Agreement is terminated pursuant to Section 10.1(b) (but not in the event of a termination as provided in Section 7.2 by virtue of the failure to satisfy the conditions set forth in clauses (a), (b) and (c) thereof by August 31, 2005) or Section 10.1(c) (unless there shall have occurred an AcquisitionCo Payment Event at such time) hereof, AcquisitionCo shall not and shall not permit any of its Subsidiaries to, in any manner whatsoever, without the prior written consent of Acetex, at any time during a period of five years from the date hereof, engage in any transaction with the Saudi Partners with respect to a Project. C-21 7.11 NOTIFICATION OF CERTAIN MATTERS Each of the Parties shall give written notice to the other of (i) any notice or other communication from any Governmental Entity in connection with the transactions contemplated by this Agreement, (ii) any action, suits, claims, investigations or proceedings commenced or threatened in writing against, relating to or involving or otherwise affecting it or any of its Subsidiaries, that relate to the consummation of the transactions contemplated by this Agreement, (iii) any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated by this Agreement, (iv) any material variances from the representations and warranties of such Party contained in this Agreement, and any other fact or event that would cause or constitute a breach of the covenants made by such Party in this Agreement, and (v) any change that could be reasonably expected to have a material adverse effect on such Party or could be reasonably expected to hinder or delay the Party's ability to consummate the transactions contemplated by this Agreement or to fulfill its respective obligations set forth herein, in each case promptly upon discovery thereof. 7.12 MERGER OF COVENANTS The covenants set out in this Agreement, except for Section 7.9 and Article 12, shall not survive the completion of the Arrangement, and shall expire and be terminated without recourse between the Parties upon such completion. ARTICLE 8 CONDITIONS 8.1 MUTUAL CONDITIONS The obligations of AcquisitionCo and Acetex to complete the transactions contemplated hereby are subject to fulfillment of the following conditions on or before the Effective Date or such other time as is specified below: (a) the Final Order shall have been granted in form and substance satisfactory to AcquisitionCo and Acetex, acting reasonably, and shall not have been set aside or modified in a manner unacceptable to such Parties, acting reasonably, on appeal or otherwise; (b) there shall be no action taken under any Laws or by any Governmental Entity, that: (i) makes illegal or otherwise directly or indirectly restrains, enjoins or prohibits the Arrangement or any other transactions or agreements contemplated herein, or materially modifies the Arrangement or any other transactions or agreements contemplated herein in a manner unacceptable to the parties acting reasonably; or (ii) results in a judgment or assessment of damages, directly or indirectly, which is material to the transactions or agreements contemplated herein; (c) (i) the issuance of an ARC pursuant to section 102 of the Competition Act by the Commissioner to the effect that she is satisfied that she would not have sufficient grounds upon which to apply to the Competition Tribunal for an order under section 92 of the Competition Act with respect to the transactions contemplated by this Agreement; or (ii) the waiver by the Commissioner under section 113(c) of the Competition Act of the obligation to notify the Commissioner and supply information because substantially similar information was previously supplied in relation to a request for an ARC, or that the waiting period under section 123 of the Competition Act has expired, and Acetex and AcquisitionCo shall have been advised in writing by the Commissioner that she has determined not to make an application for an order under section 92 of the Competition C-22 Act in respect of the transactions contemplated by this Agreement and any terms and conditions attached to any such advice shall be acceptable to Acetex and AcquisitionCo; (d) approval or deemed approval of the Arrangement pursuant to the Investment Canada Act by the Minister of Industry shall have been obtained; (e) the waiting period applicable to consummate the transactions contemplated by this Agreement under the lHSR Act shall have expired or been terminated; (f) any required approval of the Arrangement by the EC pursuant to the EC Merger Regulation shall have been obtained; and (g) all other consents, waivers, Permits and approvals of any Governmental Entity or other Person, and the expiry or termination of any waiting periods reasonably required or desirable in connection with the consummation of the transactions contemplated by this Agreement shall have been obtained and reasonably satisfactory evidence thereof shall have been delivered to each Party.

ARTICLE 10 AGREEMENT AS TO COMPENSATION AND OTHER ARRANGEMENTS 10.1 ACQUISITIONCO COMPENSATION (a) If at any time after the execution of this Agreement: (i) the Board of Directors of Acetex has withdrawn, qualified or changed any of its recommendations or determinations referred to in Section 3.3(a) in a manner permitted pursuant to Section 6.6 or shall have resolved to do so prior to the Effective Date; (ii) an Acquisition Proposal is publicly announced, proposed, offered or made to the Acetex Securityholders or to Acetex before the Acetex Meeting, and (A) such Acquisition Proposal has not expired or been withdrawn at the time of the Acetex Meeting and (B) the Acetex Securityholders do not approve the Acetex Arrangement Resolutions; or (iii) Acetex accepts, approves, recommends or enters into any agreement with respect to an Acquisition Proposal pursuant to Section 6.6; (each of the above being an "AcquisitionCo Payment Event"), then, (x) immediately prior to a termination by Acetex pursuant to Section 10.1(c)(ii), or (y) within two (2) business days of any termination of this Agreement by AcquisitionCo pursuant to Section 10.1(d), or (z) immediately prior to a termination of this Agreement by Acetex pursuant to Section 10.1(e), Acetex shall pay to AcquisitionCo ten million ($10,000,000) dollars to an account designated by AcquisitionCo. (b) For greater certainty, AcquisitionCo agrees that the compensation or damages to be received pursuant to this Section 9.1 is its sole remedy with respect to the matters referred to in Section 9.1(a) but otherwise nothing contained in this Agreement shall relieve or have the effect of relieving a Party in any way from liability for damages incurred or suffered by the other Party as a result of a breach of this Agreement by such first Party. Nothing herein shall preclude a Party from seeking injunctive relief to restrain any breach or threatened breach of the covenants or agreements set forth in this Agreement or the Confidentiality Agreement or otherwise to obtain specific performance of any of such act, covenants or agreements, without the necessity of posting bond or security in connection therewith. C-25 10.2 ACETEX COMPENSATION Pursuant to Section 6.8(b)(v), in the event this Agreement is terminated pursuant to Section 10.1(a), Section 10.1(b) (but not in the event of a termination as provided in Section 7.2) or Section 10.1(c) (unless there shall have occurred an AcquisitionCo Payment Event at such time), AcquisitionCo shall reimburse Acetex for fifty percent (50%) of the reasonable costs actually incurred by Acetex associated with the solicitation of proxies for the approval of the Acetex Arrangement Resolutions in accordance with the Acetex Circular and the Interim Order in favour of the approval of the Acetex Arrangement Resolutions.

Until surrendered as contemplated by this Section 5.1, each certificate which immediately prior to the Effective Time represented Acetex Shares, Acetex Warrants, Acetex Options or Holdco Shares (other than Acetex Securities cancelled pursuant to Section 5.3) shall be deemed at all times after the Effective Time to represent only the right to receive upon such surrender the Share Purchase Price, Warrant Purchase Price or Option Purchase Price, as the case may be, for each such Acetex Security. 5.2 LOST CERTIFICATES If any certificate, which prior to the Effective Time, represented outstanding Acetex Securities which were transferred pursuant to Section 3.1, has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such certificate to be lost, stolen or destroyed, the Depositary will issue in exchange for such lost, stolen or destroyed certificate, certificates representing Acetex Securities deliverable in respect thereof as determined in accordance with Section 3.1. When seeking such certificate and payment in exchange for any lost, stolen or destroyed certificate, the Person to whom certificates representing Acetex Securities are to be issued shall, as a condition precedent to the issuance thereof, give a bond satisfactory to Acetex and its transfer agent, in such sum as Acetex may direct, or otherwise indemnify Acetex and its transfer agent in a manner satisfactory to Acetex and its transfer agent against any claim that may be made against Acetex or its transfer agent with respect to the certificate alleged to have been lost, stolen or destroyed. 5.3 EXTINGUISHMENT OF RIGHTS Any certificate which prior to the Effective Time represented outstanding Acetex Securities which were exchanged pursuant to Section 3.1 and has not been deposited, with all other instruments required by Section 5.1, on or prior to the tenth anniversary of the Effective Date shall cease to represent a claim or interest of any kind or nature whatsoever. On such date, the Acetex Securities (and any dividends or distributions with respect thereto to which the former holder of the certificate referred to in the preceding sentence was ultimately entitled) shall be deemed to have been surrendered to Acetex, together with all entitlements to dividends, distributions, cash and interest thereon held for such former holder, for no consideration, and such shares and rights shall thereupon be cancelled and the name of the former registered holder shall be removed from the register of holders of such shares.

(b) NOTICE OF CLAIM. In the event that an Indemnified Party shall become aware of any claim, proceeding or other matter (a "Claim") in respect of which the Indemnifying Parties have agreed to indemnify the Indemnified Party pursuant to this Holdco Agreement, the Indemnified Party shall promptly give written notice thereof to the Indemnifying Parties. C(A)(I)-6 Such notice shall specify whether the Claim arises as a result of a claim by a Person against the Indemnified Party (a "Third Party Claim") and shall also specify with reasonable particularity (to the extent that the information is available) the factual basis for the Claim and the amount of the Claim, if known. The failure on the part of the Indemnified Party to so promptly notify the Indemnifying Parties shall not relieve the Indemnified Parties of any indemnification obligations hereunder, except to the extent that the Indemnifying Parties are prejudiced thereby. (c) THIRD PARTY CLAIMS. With respect to any Third Party Claim, the Indemnified Party shall have the exclusive right, at the expense of the Indemnifying Parties, to vigorously and diligently contest, settle or pay the amount claimed and to retain counsel and other experts or advisers selected by the Indemnified Party in its sole discretion in connection therewith; PROVIDED, HOWEVER, that the Indemnified Party shall not settle any Third Party Claim without the written consent of the Indemnifying Parties (which consent shall not be unreasonably withheld or delayed). If the Indemnified Party elects to assume such control, the Indemnifying Parties shall have the right, at their sole expense, to participate in the negotiation, settlement or defence of such Third Party Claim. If any Third Party Claim is of a nature such that the Indemnified Party is required by applicable Law to make a payment to any Person (a "Third Party") with respect to the Third Party Claim before the completion of settlement negotiations or related legal proceedings, the Indemnified Party may make such payment and the Indemnifying Parties shall, forthwith after demand by the Indemnified Party, reimburse the Indemnified Party for such payment. If the amount of any liability of the Indemnified Party under the Third Party Claim in respect of which such payment was made, as determined in a final non-appealable order of a court of competent jurisdiction, with such determination being the determination of the amount of any liability, is less than the amount that was paid by the Indemnifying Parties to the Indemnified Party, the Indemnified Party shall, forthwith after receipt of the difference from the Third Party, pay the amount of such difference to the Indemnifying Parties. If the Indemnified Party does not elect to assume control of the settlement or defense of a Third Party Claim, the Indemnifying Parties shall assume such control at their own expense, PROVIDED, HOWEVER, that the Indemnified Party shall have the right, at its sole expense, to participate in the negotiation, settlement or defence of such Third Party Claim. The Indemnifying Parties will have the right to defend with counsel selected by the Indemnifying Parties who shall be reasonably acceptable to the Indemnified Party, at the sole cost and expense of the Indemnifying Parties, such Third Party Claim by all appropriate proceedings, which proceedings will be vigorously and diligently prosecuted by the Indemnifying Parties to a final conclusion; PROVIDED that the Indemnifying Parties shall obtain the prior written consent of the Indemnified Parties (which consent shall not be unreasonably withheld or delayed) before entering into any settlement of a claim or ceasing to defend such claim. If the Indemnifying Parties assume the defense of a Third Party Claim, the Indemnifying Parties will have full control of such defense and proceedings, including (except as provided in the immediately preceding sentence) any settlement thereof; PROVIDED, HOWEVER, that the Indemnified Party shall have the right, at its sole expense, to participate in the negotiation, settlement or defence of such Third Party Claim it reasonably believes to be necessary or appropriate to protect its interests and not prejudicial to the Indemnifying Parties; PROVIDED, FURTHER, that the Indemnified Party may participate, at its own expense, in the defense of such Third Party Claim; and PROVIDED FURTHER, that if requested by the Indemnifying Parties, the Indemnified Party will, at the sole cost and expense of the Indemnifying Parties, cooperate with the Indemnifying Parties and their counsel in contesting any Third Party Claim that the Indemnifying Parties elect to contest, or, if appropriate and related to the Third Party Claim in question, in making any counterclaim against the Person asserting the Third Party Claim, or any cross-complaint against any Person (other than the Indemnified Party or any of its Affiliates). The Indemnified Party will be entitled to participate in any such defense with separate counsel at the expense of the Indemnifying Parties if (i) so requested by the Indemnifying Parties to participate, (ii) in the reasonable opinion of counsel to the Indemnified Party, a conflict or potential conflict exists between the Indemnified Party and the Indemnifying Parties that would make such separate representation advisable or (iii) the Indemnified Party has defenses available to it that are not available to the Indemnifying Parties. (d) PAYMENT AND COOPERATION. The Indemnifying Parties shall promptly pay to the Indemnified Party all amounts for which the Indemnifying Parties are liable pursuant to this section after the Indemnified Party C(A)(I)-7 incurs the Loss in respect of which such liability arises. The Indemnified Party and the Indemnifying Parties shall co-operate fully with each other with respect to Third Party Claims, and shall keep each other fully advised with respect thereto (including supplying copies of all relevant documentation promptly as it becomes available).

APPENDIX D GMP SECURITIES LTD. - FAIRNESS OPINION October 27, 2004 Board of Directors Acetex Corporation 999 Canada Place Vancouver, British V6C 3E1 To the Members of the Board of Directors: GMP Securities Ltd. ("GMP") understands that Acetex Corporation (the "Company" or "Acetex") and Blackstone Crystal Holdings Capital Partners (Cayman) IV Ltd. ("AcquisitionCo"), have entered into an agreement (the "Arrangement Agreement") dated October 27, 2004 pursuant to which AcquisitionCo, or its assignee, has agreed to acquire all of the issued and outstanding common shares, options and warrants of Acetex (such proposed acquisition being herein referred to as the "Transaction"). Under the Transaction, Acetex's common shareholders will receive cash consideration of $9.00 for every common share held. Acetex option holders and warrant holders will receive $9.00 cash, less the exercise price of each such option or warrant. Pursuant to the Arrangement Agreement, the obligation of AcquisitionCo is conditional upon, among other things, the Board of Directors of Acetex (the "BOD") recommending the Transaction to the holders of Acetex common shares, options and warrants and voting their securities in favor of the Transaction. GMP has been asked by the BOD to provide advice and assistance to the BOD, including the delivery to the BOD of its opinion as to the fairness of the consideration under the Transaction (the "Fairness Opinion"), from a financial point of view, to Acetex's shareholders, Acetex's warrant holders and Acetex's option holders. RELATIONSHIP WITH INTERESTED PARTIES GMP is not an insider, associate or affiliate of Acetex or AcquisitionCo or any of their affiliates or associates. In addition, GMP is not now an advisor to AcquisitionCo nor, within the past twenty four (24) months, has it participated in any financings involving AcquisitionCo, or any of its affiliates or associates. GMP acted as the financial advisor to Acetex's BOD in Acetex's acquisition of AT Plastics Inc. in June 2003. As part of its services, GMP provided Acetex's BOD with a Fairness Opinion, dated June 25, 2003, with respect to the fairness of the Transaction, from a financial point of view, to Acetex. With the exception of that work and the context of this Transaction, GMP has not provided financial advisory services to Acetex nor has it participated, within the past twenty four (24) months, in any financings involving Acetex or any of its affiliates or associates. The fees payable to GMP by Acetex arising from an engagement letter (the "Engagement Letter") pertaining to the Transaction are not contingent upon the conclusions reached by GMP in the Fairness Opinion. There are no understandings, agreements or commitments between GMP and Acetex, AcquisitionCo or any of their respective affiliates or associates with respect to any future business dealings. However, GMP may in the future, in the ordinary course of business, seek to perform financial advisory or investment banking services for any one or more of them from time to time. GMP acts as a trader and dealer, both as principal and agent, in all major Canadian financial markets and, as such, may have, or may in the future have, positions in securities of Acetex and affiliates or associates of AcquisitionCo and, from time to time, may have executed or may execute transactions on behalf of Acetex and AcquisitionCo or on behalf of other clients for which it receives compensation. As an investment dealer, GMP conducts research on securities and may, in the ordinary course of business, provide research reports and investment advice to its clients on investment matters, including matters involving an investment in Acetex or AcquisitionCo. D-2 CREDENTIALS OF GMP SECURITIES GMP is a wholly-owned Subsidiary of GMP Capital Corp. which is a publicly traded company listed on the Toronto Stock Exchange ("TSX") with offices in Toronto, Calgary and Montreal, Canada and Geneva, Switzerland. GMP provides research and securities trading services and engages in investment banking activities. GMP is not in the business of providing auditing services and is not controlled by a financial institution. The Fairness Opinion expressed herein represents the opinion of GMP, and the form and content herein have been approved for release by the Executive Committee of GMP, the members of which have extensive experience in merger, acquisition, divestiture, valuation, fairness opinion and capital market matters. SCOPE OF REVIEW The assessment of fairness, from a financial point of view, must be determined in the context of the particular transaction. In connection with our Fairness Opinion, we have reviewed and relied upon, without attempting to verify independently the completeness or accuracy of, among other things, the following: 1. certain publicly available business and financial information relating to Acetex, Blackstone and Celanese considered by us to be relevant; 2. certain public information relating to the business, financial performance and stock trading history of Acetex and compared them with those of other selected publicly traded companies considered by us to be relevant; 3. research reports prepared by equity research analysts on Acetex and the worldwide chemicals industry; 4. the financial terms of the Transaction with the financial terms of certain other transactions considered by us to be relevant; 5. the PowerPoint presentation given by Acetex to attendees of Credit Suisse First Boston's Chemicals conference held on September 20, 2004; 6. discussions of the business, financial condition and prospects for Acetex before and after giving effect to the Transaction with certain members of senior management of Acetex, its advisors and outside counsel; 7. the draft Arrangement Agreement dated October 25, 2004; 8. all press releases issued by The Blackstone Group, Acetex and Celanese for the last 3 fiscal years; 9. a schedule of Common Shares and convertible securities of Acetex outstanding as at September 30, 2004; 10. a transcript of the conference call held by Acetex on April 20, 2004, to discuss the joint venture with National Petrochemical Industrialization Company (TASNEE Petrochemical) to construct facilities in Jubail, Kingdom of Saudi Arabia; 11. the business plans, forecasts and budgets prepared by management of Acetex for the fiscal years ended 2004 and 2005; 12. draft memorandum written by Law & Economics Consulting Group (LECG) dated September 16, 2004, with an analysis of the geographic markets for Acetex's products; 13. public information with respect to transactions of a nature comparable to the Transaction which we considered to be relevant; and 14. other such corporate, industry and financial market information, investigations and analyses as GMP considered necessary or appropriate under the circumstances. 15. GMP has not, to the best of our knowledge, been denied access by Acetex to any information requested. D-3 ASSUMPTIONS AND LIMITATIONS GMP understands that considerable time could elapse between the announcement of the Transaction and Closing given that different government agencies may review the Transaction from the perspective of its effect on the competition within their respective markets. In addition, these agencies have the power to make their approvals conditional upon modifications or amendments to the terms of the Transaction. In the event that significant modifications or amendments are imposed to complete the Transaction, neither Acetex not AcquisitionCo, is obligated to proceed with the Transaction. Furthermore, the Arrangement Agreement specifies that the date (the "Effective Date") wherein all such decisions must be concluded is August 31, 2005, otherwise, the Transaction may be terminated by either Acetex or AcquisitionCo. Given that it is not possible to determine the length of time likely to evolve in relation to this process or its ultimate outcome, GMP has not, in determining the fairness of the Transaction to the common shareholders, option holders and warrant holders of Acetex, attempted to quantify the potential impact of this process or predict the impact of any imposed amendments to the Transaction on the business and operations of Acetex. With the approval of the BOD and as is provided for in the Engagement Letter, GMP has relied upon the completeness, accuracy and fair presentation of all of the financial and other information, data, advice, opinions and representations obtained by it from public sources, senior management of Acetex and AcquisitionCo, and their respective consultants and advisors (collectively, the "Information"). The Fairness Opinion is conditional upon the completeness, accuracy and fair presentation of such Information. Subject to the exercise of professional judgment and except as expressly described herein, we have not attempted to verify independently the completeness, accuracy or fair presentation of any of the Information. The Chief Executive Officer and Chief Financial Officer of Acetex have represented to GMP in a certificate delivered as of the date of this Fairness Opinion, among other things, that (i) the Information obtained from public sources or provided orally by, or in the presence of, an officer of Acetex or in writing by Acetex or orally or in writing by agents of Acetex to GMP relating to Acetex or the Transaction for the purpose of preparing the Fairness Opinion was, at the date the Information was provided to GMP, and is, except as has been disclosed in writing to GMP, complete, true and correct in all material respects, and did not and does not contain any untrue statement of a material fact (as such term is defined in the SECURITIES ACT (Ontario) (the "Act")) in respect of Acetex or the Transaction or omit to state a material fact (as the term is defined in the Act) necessary to make the Information not misleading in light of the circumstances under which the Information was made or provided; and (ii) since the dates on which the Information was disclosed or provided to GMP, except as disclosed in writing to GMP, there has been no material change (as such term is defined in the Act), financial or otherwise, in the financial condition, assets, liabilities (contingent or otherwise), business, operations or prospects of Acetex and no material change has occurred in the Information or any part thereof which would have or which would reasonably be expected to have a material effect on the Fairness Opinion. With reference to the budgets, forecasts, projections or estimates provided to GMP by management of Acetex and used in its analyses, GMP notes that projecting future results of any company is inherently subject to uncertainty. It has been represented to GMP by the Chief Executive Officer and Chief Financial Officer of Acetex in writing that such budgets, forecasts, projections and estimates were prepared using the assumptions identified therein which, in the reasonable belief of Acetex are (or were at the time of preparation) reasonable in the circumstances and are not misleading in any material respect in light of the assumptions used therefor. The Fairness Opinion is rendered on the basis of securities markets, economic, financial and general business conditions prevailing as at the date hereof and the condition and prospects, financial and otherwise, of Acetex and its respective subsidiaries and affiliates, as they were reflected in the Information and as they have been represented to GMP in discussions with management of Acetex. In its analyses and in preparing the Fairness Opinion, GMP has made numerous assumptions with respect to industry performance, general business and economic conditions and other regulatory matters, many of which are beyond the control of GMP or any party involved in the Transaction and, while reasonable under current circumstances, may prove to be incorrect. The Fairness Opinion has been provided for the use of the BOD for purposes of considering the Transaction. The Fairness Opinion may not be used by any person or relied upon by any other person other than BOD and may not be used or relied upon by the BOD for any purpose other than the purpose hereinbefore stated, without the express prior written consent of GMP. The Fairness Opinion is given as of the date hereof, and GMP disclaims any undertaking or obligation to advise any person of any change in any fact or matter affecting the Fairness Opinion which may come or be brought to GMP's attention after the date hereof. Without limiting the foregoing, in the event that there is any material change in any fact or matter affecting the Fairness Opinion after the date hereof, GMP reserves the right to change, modify or withdraw the Fairness Opinion. D-4 FAIRNESS OPINION Based on and subject to the foregoing, GMP is of the opinion that, as at October 27, 2004, the consideration to be received under the Transaction by Acetex's shareholders, Acetex's warrant holders and Acetex's option holders is fair, from a financial point of view, to Acetex's shareholders, Acetex's warrant holders and Acetex's option holders. Yours very truly, /s/ GMP Securities Ltd.

SUCH RIGHT OF DISSENT IS DESCRIBED IN THE CIRCULAR. THE FULL TEXT OF SECTION 191 OF THE ABCA IS SET FORTH BELOW. NOTE THAT CERTAIN PROVISIONS OF SUCH SECTIONS HAVE BEEN MODIFIED BY THE INTERIM ORDER, WHICH IS ATTACHED TO THE CIRCULAR. AS APPENDIX B AND PURSUANT TO THE PLAN OF ARRANGEMENT, A COPY OF WHICH IS ATTACHED AS SCHEDULE A TO THE ARRANGEMENT AGREEMENT, WHICH IS ATTACHED TO THE CIRCULAR AS APPENDIX C. 1. "191(1) Subject to sections 192 and 242, a holder of shares of any class of a corporation may dissent if the corporation resolves to (a) amend its articles under section 173 or 174 to add, change or remove any provisions restricting or constraining the issue or transfer of shares of that class, (b) amend its articles under section 173 to add, change or remove any restrictions on the business or businesses that the corporation may carry on, (c) amalgamate with another corporation, otherwise than under section 184 or 187, (d) be continued under the laws of another jurisdiction under section 189, or (e) sell, lease or exchange all or substantially all its property under section 190. 2. A holder of shares of any class or series of shares entitled to vote under section 176, other than section 176(l)(a), may dissent if the corporation resolves to amend its articles in a manner described in that section. 3. In addition to any other right the shareholder may have, but subject to subsection (20), a shareholder entitled to dissent under this section and who complies with this section is entitled to be paid by the corporation the fair value of the shares held by the shareholder in respect of which the shareholder dissents, determined as of the close of business on the last business day before the day on which the resolution from which the shareholder dissents was adopted. 4. A dissenting shareholder may only claim under this section with respect to all the shares of a class held by the shareholder or on behalf of any one beneficial owner and registered in the name of the dissenting shareholder. 5. A dissenting shareholder shall send to the corporation a written objection to a resolution referred to in subsection (1) or (2) (a) at or before any meeting of shareholder at which the resolution is to be voted on, or (b) if the corporation did not send notice to the shareholder of the purpose of the meeting or of the shareholder's right to dissent, within a reasonable time after the shareholder learns that the resolution was adopted and of the shareholder's right to dissent. 6. An application may be made to the Court by originating notice after the adoption of a resolution referred to in subsection (1) or (2) (a) by the corporation, or (b) by a shareholder if the shareholder has sent an objection to the corporation under subsection (5), to fix the fair value in accordance with subsection (3) of the shares of a shareholder who dissents under this section. E-2 7. If an application is made under subsection (6), the corporation shall, unless the Court otherwise orders, send to each dissenting shareholder a written offer to pay the shareholder an amount considered by the directors to be the fair value of the shares. 8. Unless the Court otherwise orders, an offer referred to in subsection (7) shall be sent to each dissenting shareholder (a) at least 10 days before the date on which the application is returnable, if the corporation is the applicant, or (b) within 10 days after the corporation is served with a copy of the originating notice, if a shareholder is the applicant. 9. Every offer made under subsection (7) shall (a) be made on the same terms, and (b) contain or be accompanied by a statement showing how the fair value was determined. 10. A dissenting shareholder may make an agreement with the corporation for the purchase of the shareholder's shares by the corporation, in the amount of the corporation's offer under subsection (7) or otherwise, at any time before the Court pronounces an order fixing the fair value of the shares. 11. A dissenting shareholder (a) is not required to give security for costs in respect of an application under subsection (6), and (b) except in special circumstances must not be required to pay the costs of the application or appraisal. 12. In connection with an application under subsection (6), the Court may give directions for (a) joining as parties all dissenting shareholders whose shares have not been purchased by the corporation and for the representation of dissenting shareholders who, in the opinion of the Court, are in need of representation, (b) the trial of issues and interlocutory matters, including pleadings and examinations for discovery, (c) the payment to the shareholder of all or part of the sum offered by the corporation for the shares, (d) the deposit of the share certificates with the Court or with the corporation or its transfer agent, (e) the appointment and payment of independent appraisers, and the procedures to be followed by them, (f) the service of documents, and (g) the burden of proof on the parties. 13. On an application under subsection (6), the Court shall make an order (a) fixing the fair value of the shares in accordance with subsection (3) of all dissenting shareholders who are parties to the application, E-3 (b) giving judgment in that amount against the corporation and in favour of each of those dissenting shareholders, and (c) fixing the time within which the corporation must pay that amount to a shareholder. 14. On (a) the action approved by the resolution from which the shareholder dissents becoming effective, (b) the making of an agreement under subsection (10) between the corporation and the dissenting shareholder as to the payment to be made by the corporation for the shareholder's shares, whether by the acceptance of the corporation's offer under subsection (7) or otherwise, or (c) the pronouncement of an order under subsection (13), whichever first occurs, the shareholder ceases to have any rights as a shareholder other than the right to be paid the fair value of the shareholder's shares in the amount agreed to between the corporation and the shareholder or in the amount of the judgment, as the case may be. 15. Subsection (14)(a) does not apply to a shareholder referred to in subsection (5)(b). 16. Until one of the events mentioned in subsection (14) occurs (a) the shareholder may withdraw his dissent, or (b) the corporation may rescind the resolution, and in either event proceedings under this section shall be discontinued. 17. The Court may in its discretion allow a reasonable rate of interest on the amount payable to each dissenting shareholder, from the date on which the shareholder ceases to have any rights as a shareholder by reason of subsection (14) until the date of payment. 18. If subsection (20) applies, the corporation shall, within 10 days after (a) the pronouncement of an order under subsection (13), or (b) the making of an agreement between the shareholder and the corporation as to the payment to be made for the shareholder's shares, notify each dissenting shareholder that it is unable lawfully to pay dissenting shareholders for their shares. 19. Notwithstanding that a judgment has been given in favour of a dissenting shareholder under subsection (13)(b), if subsection (20) applies, the dissenting shareholder, by written notice delivered to the corporation within 30 days after receiving the notice under subsection (18), may withdraw the shareholder's notice of objection, in which case the corporation is deemed to consent to the withdrawal and the shareholder is reinstated to the shareholder's full rights as a shareholder, failing which the shareholder retains a status as a claimant against the corporation, to be paid as soon as the corporation is lawfully able to do so or, in a liquidation, to be ranked subordinate to the rights of creditors of the corporation but in priority to its shareholders. 20. A corporation shall not make a payment to a dissenting shareholder under this section if there are reasonable grounds for believing that (a) the corporation is or would after the payment be unable to pay its liabilities as they become due, or E-4 (b) the realizable value of the corporation's assets would thereby be less than the aggregate of its liabilities."
