2.1  AMALGAMATION

         (i)   AT Plastics and Acetex Sub shall amalgamate pursuant to the
               provisions of section 175 of the OBCA and the Articles of
               Amalgamation shall be filed;

               for each AT Plastics Share held;

(b)      On the Effective Date each AT Plastics Option will, without any further
         action on the part of any AT Plastics Optionholder, become an option
         (remaining under the AT Plastics Option Plan) to purchase the number of
         Acetex Shares determined by dividing the number of AT Plastics Shares
         subject to the particular AT Plastics Option at the Effective Date by
         6, at an exercise price per Acetex Shares equal to the exercise price
         per share in the particular AT Plastics Option at the Effective Time
         multiplied by 6. If the foregoing calculation results in an option
         being exercisable for a fraction of an Acetex Share then the number of
         Acetex Shares subject to such option will be rounded down to the
         nearest whole number of shares, and the exercise price per whole Acetex
         Share will be as determined above. The obligations of AT Plastics under

         Option Plan, the address for exercise of such converted options shall

         this subsection, the term, exerciseability and all other terms and
         conditions of the AT Plastics Options in effect at the Effective Date
         shall govern the AT Plastics Options as so converted.

(c)      On the Effective Date the AT Plastics Warrants shall be cancelled and
         extinguished and in consideration therefore Peninsula Fund III, L.P.
         shall be entitled to receive Acetex Substitute Warrant #1 entitling it
         to acquire 706,760 Acetex Shares at an exercise price equal to the
         closing price of the Acetex Shares on the Toronto Stock Exchange on the
         Effective Date or if there is no closing price on the Effective Date
         the next day on which there is a trade on the Toronto Stock Exchange
         and Connecticut General Life Insurance shall be entitled to receive
         Acetex Substitute Warrant #2 entitling it to acquire 141,352 Acetex

                    cancellation on the Effective Date; or



               (B)  is ultimately not entitled to be paid fair value for such
                    shareholder's AT Plastics Shares, for any reason, shall be
                    deemed to have participated in the Amalgamation on the same
                    basis as at and from the Effective Date as any other
                    non-dissenting AT Plastics Shareholder;

         (ii)  Acetex shall not be required to recognize AT Plastics
               Shareholders described in paragraph 2.1(c)(i)(A) above as holding
               AT Plastics Shares on or after the Effective Date and the names

               Plastics;

         At or promptly after the Effective Date, Acetex shall deposit with the
Depository, for the benefit of the former AT Plastics Shareholders who exchanged
AT Plastics Shares pursuant to the Amalgamation, certificates representing the
Acetex Shares issued pursuant to the Amalgamation. Upon surrender to the
Depository, at any of its offices specified in the Letter of Transmittal, of a
certificate which prior to the Effective Date represented outstanding AT
Plastics Shares, and such additional documents and instruments as the Depository
may reasonably require, the holder of such surrendered certificate shall be
entitled to receive in exchange therefor, and the Depository shall forthwith
deliver to such holder, a certificate representing that number (rounded down to
the nearest whole number) of Acetex Shares which such holder received pursuant
to the Amalgamation (together with any dividends or distributions with respect
thereto pursuant to Section 2.3 and any cash in lieu of fractional Acetex Shares
pursuant to Section 2.4), and any certificate so surrendered shall forthwith be
cancelled. In the event of a transfer of ownership of AT Plastics Shares which
is not registered in the transfer records of AT Plastics, a certificate
representing the proper number of Acetex Shares (together with any dividends or
distributions with respect thereto pursuant to Section 2.3 and any cash in lieu
of fractional Acetex Shares pursuant to Section 2.4) shall be delivered to a
transferee if the certificate formerly representing such AT Plastics Shares is
presented to the Depository at its offices as aforesaid, accompanied by the
foregoing documents together with all other documents required to evidence and
effect such transfer. Until surrendered as contemplated by this Section 2.2,
each certificate which prior to the Effective Date represented outstanding AT
Plastics Shares shall be deemed at any time after the Effective Date, to
represent only the right to receive upon such surrender (a) the certificate
representing Acetex Shares as contemplated by this Section 2.2, (b) a cash
payment in lieu of any fractional Acetex Shares as contemplated by Section 2.4,
and (c) any dividends or distributions with a record date on or after the
Effective Date theretofore paid or payable with respect to Acetex Shares as
contemplated by Section 2.3.

2.3      DIVIDENDS AND OTHER DISTRIBUTIONS

         No dividends or other distributions declared or made on or after the
Effective Date with respect to the Acetex Shares with a record date on or after
the Effective Date shall be paid to the holder of any certificates formerly
representing outstanding AT Plastics Shares which are not surrendered pursuant



to Section 2.2 and no cash payment in lieu of fractional shares shall be paid to
any such holder pursuant to Section 2.4 (and no interest will be earned and
payable thereon), unless and until the certificate representing such AT Plastics
Shares shall be surrendered in accordance with Section 2.2. Subject to
applicable law, at the time of such surrender of any such certificate (or, in
the case of clause (c) below, at the appropriate payment date), there shall be
paid to the holder of the Acetex Shares issued pursuant to the Amalgamation, in
all cases without interest, (a) the amount of any cash payable in lieu of a
fractional Acetex Shares to which such holder is entitled pursuant to Section
2.4, (b) the amount of dividends or other distributions with a record date on or
after the Effective Date theretofore paid with respect to such Acetex Shares,
and (c) the amount of dividends or other distributions with a record date on or
after the Effective Date but prior to surrender and a payment date subsequent to
surrender payable with respect to such Acetex Shares.

2.4      NO FRACTIONAL SHARES

         No certificates or scrip representing fractional Acetex Shares shall be
issued upon the surrender for exchange of certificates pursuant to Section 2.2,
and such fractional interests shall not entitle the owner thereof to vote or to
possess or exercise any rights as a security holder of Acetex. In lieu of any
such fractional interests, each person entitled thereto, will receive an amount
of cash (rounded to the nearest whole cent), without interest, equal to the
product of (a) such fractional interest, multiplied by (b) the average of the
closing trading price for Acetex Shares on the Toronto Stock Exchange for the
first three trading days on which Acetex Shares are traded following the
Effective Date, such amount to be provided to the Depository by Acetex upon
request.

2.5      LOST CERTIFICATES

         If any certificate which prior to the Effective Date represented
outstanding AT Plastics Shares 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 Depository will issue in exchange for such
lost, stolen or destroyed certificate, certificates representing Acetex Shares
(together with any dividends or distributions with respect thereto pursuant to
Section 2.3 and any cash in lieu of fractional Acetex Shares pursuant to Section
2.4) deliverable in respect thereof as determined in accordance with Section
2.2. When seeking such certificate and payment in exchange for any lost, stolen
or destroyed certificate, the person to whom certificates representing Acetex
Shares 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.

2.6      EXTINGUISHMENT OF RIGHTS

         Any certificate which prior to the Effective Date represented
outstanding AT Plastics Shares and has not been deposited on or prior to the
tenth anniversary of the Effective Date shall cease to represent a claim or
interest of any kind or nature as a shareholder or a holder of Acetex Shares or
AT Plastics Shares. On such date, the Acetex Shares (and any dividends or
distributions with respect thereto pursuant to Section 2.3 and any cash in lieu
of fractional Acetex Shares pursuant to Section 2.4) 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.



2.7      CONVERTED AT PLASTICS OPTION

         As soon as practical after the Effective Date, Acetex shall confirm in
writing to each of the former holders of AT Plastics Options the terms of their
options for Acetex Shares into which their AT Plastics Options have been
converted pursuant to subsection 2.1(b).

5.1      CORPORATE GOVERNANCE

         The Parties agree to use their best efforts to cause the Governance
Arrangements set out in Schedule D, including without limitation, the matters
contained in Section 1 of Schedule D, to become effective upon the Amalgamation
becoming effective or immediately thereafter.

5.2      CONSULTATION

         Acetex and AT Plastics agree to consult with each other in issuing any
press releases or otherwise making public statements with respect to this
Agreement or the Amalgamation and in making any filing with any Governmental
Entity or with any stock exchange with respect thereto. Each Party shall use all
reasonable commercial efforts to enable the other Party to review and comment on
all such press releases prior to the release thereof and to enable the other
Party to review and comment on such filings prior to the filing thereof. The
Parties agree to issue jointly a press release with respect to this Agreement as
soon as practicable, in a form acceptable to both Parties.



5.3      MUTUAL COVENANTS

         Each of the Parties covenants and agrees that, except as contemplated
in this Agreement or the Amalgamation, until the Effective Date or the day upon
which this Agreement is terminated, whichever is earlier:

(a)  except as previously disclosed in writing to, or with the prior written
     consent of, the other Party hereto, it shall, and shall cause each of its
     Subsidiaries to, conduct its and their respective businesses only in, and
     not take any action except in, the usual, ordinary and regular course of
     business and consistent with past practices;

(b)  except as previously disclosed in writing to the other Party, including in
     paragraph 2 of Schedule C hereto or except in respect of internal
     transactions involving a Party and its wholly-owned Subsidiaries or among
     such Subsidiaries, it shall not, without the prior written consent of the
     other Party hereto, which shall not be unreasonably withheld or delayed,
     directly or indirectly, including through a Subsidiary, do or permit to
     occur any of the following:

     (i)     issue, sell, pledge, lease, dispose of, encumber or agree to issue,
             sell, pledge, lease, dispose of or encumber (or permit any of its
             Subsidiaries to issue, sell, pledge, lease, dispose of, encumber or
             agree to issue, sell, pledge, lease, dispose of or encumber):

             (A)    any shares of, or any options, warrants, calls, conversion
                    privileges or rights of any kind to acquire any shares of it
                    or any of its Subsidiaries, except pursuant to the exercise
                    of stock options currently outstanding or under existing
                    share issuance plans which have been disclosed to the other
                    Party to this Agreement and except for stock options issued
                    to new hires in accordance with past practices and shares
                    issued in respect thereof; and as Acetex may deem
                    appropriate or necessary for purposes of refinancing the
                    debt of the Amalgamated Corporation; or

             (B)    except in the usual, ordinary and regular course of business
                    and consistent with past practice, any material assets of it
                    or any of its Material Subsidiaries;

     (ii)    amend or propose to amend its articles or by-laws or those of any
             of its Material Subsidiaries;

             shares;

     (iv)    redeem, purchase or offer to purchase (or permit any of its

             shares or other securities of it or any of its Material
             Subsidiaries, unless otherwise required by the terms of such
             securities;

     (v)     reorganize, amalgamate or merge it or any of its Material
             Subsidiaries with any other person, corporation, partnership or
             other business organization whatsoever;

     (vi)    except in the usual, ordinary and regular course of business and
             consistent with past practice, acquire, agree to acquire, dispose
             of or agree to dispose of any person, corporation, partnership,
             joint venture or other business organization or division or


             acquire, agree to acquire, dispose of or agree to dispose of any
             assets, which, in each case, are individually or in the aggregate
             material;

     (vii)   except in the usual, ordinary and regular course of business and

             renewal of or the replacement of existing credit facilities where
             such renewal or replacement facilities are for a principal amount

(c)  except as may be required under the Lender Consents, without the prior
     written consent of the other Party hereto, which shall not be unreasonably
     withheld or delayed, it shall not, and shall cause each of its Subsidiaries
     not to:

     (i)     other than as previously disclosed in writing to the other Party
             hereto or in the usual, ordinary and regular course of business and
             consistent with past practice or pursuant to existing employment,
             pension, supplemental pension, termination, compensation
             arrangements or policies, enter into or modify any employment,
             severance, collective bargaining or similar agreements, policies or
             arrangements with, or grant any bonuses, salary increases, stock
             options, pension or supplemental pension benefits, profit sharing,
             retirement allowances, deferred compensation, incentive
             compensation, severance or termination pay to, or make any loan to,
             any officers or directors of it or any Subsidiary;

     (ii)    other than as previously disclosed in writing to the other Party
             hereto or in the usual, ordinary and regular course of business and
             consistent with past practice or pursuant to existing employment,
             pension, supplemental pension, termination, compensation
             arrangements or policies, in the case of employees of it or any of
             its Subsidiaries who are not officers or directors, take any action
             with respect to the entering into or modifying of any employment,
             severance, collective bargaining or similar agreements, policies or
             arrangements or with respect to the grant of any bonuses, salary
             increases, stock options, pension or supplemental pension benefits,
             profit sharing, retirement allowances, deferred compensation,
             incentive compensation, severance or termination pay or any other
             form of compensation or profit sharing or with respect to any
             increase of benefits payable (provided that Acetex consents to the
             acceleration of vesting of all options under the AT Plastics Option
             Plan upon the Amalgamation becoming effective); or

     (iii)   except as set forth in the Parties' previously approved respective
             capital budgets (copies of which have been previously provided to
             the other Party), incur or commit to capital expenditures prior to
             the Effective Date individually or in the aggregate exceeding
             $250,000;

(d)  it shall use its reasonable commercial efforts (taking into account
     insurance market conditions and offerings and industry practices) to cause
     its current insurance (or re-insurance) policies not to be cancelled or
     terminated or any of the coverage thereunder to lapse, except where such



     cancellation, termination or lapse would not individually or in the
     aggregate have a material adverse effect, unless simultaneously with such
     termination, cancellation or lapse, replacement policies underwritten by
     insurance and re-insurance companies of nationally recognized standing
     providing coverage equal to or greater than the coverage under the
     cancelled, terminated or lapsed policies for substantially similar premiums
     are in full force and effect;

(e)  it shall:

     (i)     use its reasonable commercial efforts, and cause each of its
             Subsidiaries 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;

     (ii)    not take any action, or permit any of its Subsidiaries to take any
             action that would interfere with or be inconsistent with the
             completion of the transactions contemplated hereunder or would
             render, or that reasonably may be expected to render, any
             representation or warranty made by it in this Agreement untrue in
             any material respect at any time prior to the Effective Date if
             then made (other than a change of recommendation in accordance with
             Section 5.4 and the communication of such change); and

     (iii)   promptly notify the other Party to this Agreement of any material
             adverse change, or any change which could reasonably be expected to
             become a material adverse change, in respect of its or any of its
             Subsidiaries' businesses or in the operation of its or any of its
             Subsidiaries' businesses or in the operation of its or any of its
             Subsidiaries' properties, and of any material Governmental Entity
             or third party complaints, investigations or hearings (or
             communications indicating that the same may be contemplated);

(f)  except in connection with the Lender Consents, 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
     this Agreement or the Amalgamation prior to the Effective Date without the
     prior written consent, not to be unreasonably withheld or delayed, of the
     other Party to this Agreement;

(g)  except in the usual, ordinary and regular course of business and consistent
     with past practice, or except as previously disclosed in writing to the
     other Party hereto or as required by applicable Laws, it and its
     Subsidiaries shall not enter into or modify in any material respect any
     contract, agreement, commitment or arrangement which new contract or series
     of related new contracts or modification to an existing contract or series
     of related existing contracts would be material to a Party hereto or which
     would have a material adverse effect on a Party hereto;

(h)  it shall use all reasonable commercial efforts to satisfy (or cause the
     satisfaction of) the conditions precedent to its obligations hereunder set
     forth in Article 6 to the extent the same is within its control and take,
     or cause to be taken, all other action and to do, or cause to be done, all
     other things necessary, proper or advisable under all applicable Laws to
     complete the Amalgamation, including using its reasonable commercial
     efforts to:

     (i)     obtain all necessary waivers, consents and approvals required to be
             obtained by it from other parties to loan agreements, leases and
             other contracts;



     (ii)    obtain all necessary consents, approvals and authorizations as are
             required to be obtained by it under any applicable Laws;

     (iii)   effect all necessary registrations and filings and submissions of
             information requested by Governmental Entities required to be
             effected by it in connection with the Amalgamation and participate
             and appear in any proceedings of either Party before Governmental
             Entities in connection with the Amalgamation;

     (iv)    oppose, lift or rescind any injunction or restraining order or
             other order or action seeking to stop, or otherwise adversely
             affecting the ability of the Parties to consummate, the
             transactions contemplated hereby or by the Amalgamation;

     (v)     fulfill all conditions and satisfy all provisions of this Agreement
             and the Amalgamation, including delivery of the certificates of
             their respective officers contemplated by Section 6.2 and Section
             6.3; and

     (vi)    cooperate with the other Party to this Agreement in connection with
             the performance by it of its obligations hereunder;

     (vii)   it shall not take any action, refrain from taking any action, or
             permit any action to be taken or not taken, inconsistent with this
             Agreement or which would reasonably be expected to significantly
             impede the consummation of the Amalgamation (other than a change of
             recommendation in accordance with Section 5.4 and the communication
             of such change);

(i)  subject to the Confidentiality Agreement and Section 5.7, it will, in all
     material respects, conduct itself so as to keep the other Parties to this
     Agreement fully informed as to the material decisions required to be made
     or actions required to be taken with respect to the operation of its
     business, provided that such disclosure is not otherwise prohibited by
     reason of a confidentiality obligation owed to a third party for which a
     waiver could not be obtained or is with respect to customer specific or
     competitively sensitive information relating to areas or projects where
     Acetex and AT Plastics are competitors;

(j)  it shall discuss and consider such Pre-Amalgamation Steps as may be
     proposed by the other Party hereto and implement such Pre-Amalgamation
     Steps that it considers to be in the best interests of its shareholders,
     provided such steps are agreed to in writing by the other Party hereto;

(k)  it shall make or cooperate as necessary in the making of all necessary
     filings and applications under all applicable Laws required in connection
     with the transactions contemplated herein and take all reasonable action
     necessary to be in compliance with such Laws; and

(l)  it shall use its reasonable commercial efforts to conduct its affairs so
     that all of its representations and warranties contained herein shall be
     true and correct in all material respects on and as of the Effective Date
     as if made thereon.

5.4      RECOMMENDATION OF BOARDS OF DIRECTORS

         The AT Plastics Circular shall include the recommendation and
representation of the AT Plastics Board of Directors to its security holders in
respect of the Amalgamation as set out in Section 2.9. Notwithstanding any other
provision of this Agreement, the Board of Directors of AT Plastics may change
its recommendation to its securityholders in respect of the Amalgamation from
that set forth in



Sections 2.9, if such Board concludes, in good faith, after receiving the advice
of outside counsel and financial advisors that is reflected in the minutes of a
meeting of the Board, that such action is necessary for such Board to act in a
manner consistent with its fiduciary duty or applicable Laws and, in the event
that Sections 5.5, 5.6 or 8.2 are applicable, if such Party and its Board are in
compliance with those sections and such Party has paid any fee applicable under
Article 8. The foregoing shall not relieve the Board of Directors of AT Plastics
from its obligation to proceed to call and hold the AT Plastics Meeting, solicit
proxies for such meeting and to hold the vote of AT Plastics Shareholders.

5.5      MUTUAL COVENANT REGARDING NON-SOLICITATION

(a)  Neither Acetex nor AT Plastics, nor their respective Subsidiaries shall,
     directly or indirectly, through any officer, director, employee,
     representative or agent of Acetex or AT Plastics, as the case may be,
     solicit, initiate, invite or knowingly encourage (including by way of
     furnishing confidential information or entering into any form of agreement,
     arrangement or understanding) the initiation of or participate in, any
     inquiries or proposals regarding an Acquisition Proposal, provided that
     nothing contained in this Section 5.5 or other provisions of this Agreement
     shall prevent the Board of Directors of Acetex or AT Plastics from
     considering, negotiating, approving or recommending to its shareholders an
     agreement in respect of an unsolicited bona fide written Acquisition
     Proposal (i) in respect of which any required financing has been
     demonstrated to the satisfaction of the Board of Directors of the Party
     subject to the Acquisition Proposal, 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 a
     Party hereto or any of its Subsidiaries or their representatives beyond
     5:00 p.m. (Eastern Daylight 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); (iii) in respect of which the
     Board of Directors of the Party subject to the Acquisition Proposal
     determines (having consulted outside counsel) that in the exercise of its
     fiduciary duty it would be necessary for such Board of Directors to take
     such action in order to avoid breaching its fiduciary duties; and (iv) in
     respect of which the Board of Directors of the Party subject to the
     Acquisition Proposal determines in good faith, after consultation with
     financial advisors, if consummated in accordance with its terms, would
     result in a transaction more favourable to its shareholders than the
     Amalgamation (any such Acquisition Proposal that satisfies clauses (i)
     through (iv) above being referred to herein as a "Superior Proposal").

(b)  Subject to the ability of the Parties to carry on business in accordance
     with Section 5.3, Acetex and AT Plastics shall continue to refrain from
     participating in any discussions or negotiations with any parties (other
     than the other Party hereto) with respect to any potential Acquisition
     Proposal. Acetex and AT Plastics agree 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 and AT Plastics further agree 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. Acetex and AT Plastics 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 or AT Plastics, as the case may be, and
     shall use all reasonable efforts to ensure that such requests are honoured.

(c)  Each of Acetex and AT Plastics shall immediately notify the other Party
     (orally and in writing) of any future Acquisition Proposal of which such
     Party's directors or senior officers become aware, or any amendments to the
     foregoing, or any request for non-public information relating to Acetex or
     AT Plastics, as the case may be, or any of such Party's Material
     Subsidiaries in connection with



     an Acquisition Proposal or for access to the properties, books or records
     or for a list of the shareholders of such Party or any Material Subsidiary
     by any person or entity that informs such Party or such Material 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 the other Party hereto 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 or AT Plastics receives a request for material non-public
     information from a person who proposes a bona fide Acquisition Proposal in
     respect of Acetex or AT Plastics, and the Board of Directors of such Party
     determines that such proposal would be a Superior Proposal pursuant to
     Section 5.5(a), assuming the satisfactory outcome of a due diligence
     condition which conforms to Section 5.5(a), then, and only in such case,
     the Board of Directors may, subject to the execution of a confidentiality
     agreement containing a standstill provision substantially similar to that
     contained in Article 7 of 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
     such Party sends a copy of any such confidentiality agreement to the other
     Party immediately upon its execution, only provide such person with access,
     in accordance with Section 5.5(a) to the same information previously
     provided to the other Party. The Party providing access shall provide the
     other Party with a list of the information provided to the person making
     the Superior Proposal.

(e)  Each Party hereto shall ensure that its directors and officers and its
     Subsidiaries and any financial advisors or other advisors or
     representatives retained by it are aware of the provisions of this Section,
     and it shall be responsible for any breach of this Section 5.5 by its
     financial advisors or other advisors or representatives.

5.6      NOTICE OF SUPERIOR PROPOSAL DETERMINATION

         Neither Acetex nor AT Plastics shall accept, approve or recommend or
enter into any agreement (except for a confidentiality agreement pursuant to
Section 5.5(d)) in respect of an Acquisition Proposal on the basis that it
constitutes a Superior Proposal unless (i) it has provided the other Party
hereto with a copy of the Acquisition Proposal document which has been
determined to be a Superior Proposal, with such deletions as are necessary to
protect confidential portions of such Acquisition Proposal document, provided
that the material terms, conditions and the identity of the person, and
controlling person, if any, making the Acquisition Proposal may not be deleted;
(ii) five (5) business days (the "Notice Period") shall have elapsed from the
later of the date the other Party received notice of the determination to
accept, approve or recommend an agreement in respect of such Acquisition
Proposal, and the date such Party received a copy of the Acquisition Proposal
document; (iii) it has paid to the other Party the fee payable under Sections
8.1 or 8.2, as the case may be; and (iv) it concurrently terminates this
Agreement pursuant to Sections 9.1(e) or (f), as the case may be. During the
Notice Period, the Party receiving or subject to the Superior Proposal shall
provide a reasonable opportunity to the other Party to consider, discuss and
offer such adjustments in the terms and conditions of this Agreement as would
enable the Party receiving the Superior Proposal to proceed with its
recommendation to securityholders with respect to the Amalgamation; provided
however that any such adjustment shall be at the discretion of the Parties at
the time. The Board of Directors of the Party receiving or subject to the
Superior Proposal will review in good faith any offer made by the other Party 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. If the Board of Directors of the Party determines that the
Superior Proposal would cease to be a Superior Proposal, it will so advise the
other Party and will accept the offer by the other Party 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 the Party subject to or receiving the Superior Proposal 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 the other Party hereto, that Party
may, subject to the terms of this Agreement including the payment of applicable
fees under Article 8, accept, approve, recommend or enter into an agreement,
understanding or arrangement in respect of such Superior Proposal. Each
successive material modification of any Acquisition Proposal or a Superior
Proposal shall constitute a new Acquisition Proposal for the purposes of this
Section 5.6 and shall require a five (5) business day Notice Period from the
date such amendment is communicated to the other Party hereto (other than an
amendment to improve upon a Superior Proposal in respect of which the other
Party 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). Information provided hereunder shall constitute
confidential information under the Confidentiality Agreement.

5.7      ACCESS TO INFORMATION

         Subject to the Confidentiality Agreement and applicable Laws, upon
reasonable notice, AT Plastics shall (and shall cause each of its Subsidiaries
to) afford the officers, employees, counsel, accountants and other authorized
representatives and advisors ("Representatives") of Acetex access, during normal
business hours from the date hereof and until the earlier of the Effective Date
or the termination of this Agreement, to its properties, books, contracts and
records as well as to its management personnel, and, during such period, AT
Plastics shall (and shall cause each of its Subsidiaries to) furnish promptly to
Acetex all information concerning its business, properties and personnel as
Acetex may reasonably request. Subject to the Confidentiality Agreement and
applicable Laws, upon reasonable notice, Acetex shall (and shall cause each of
its Subsidiaries to) provide the same access to AT Plastics and its
Representatives on the same terms and conditions. Nothing in the foregoing shall
require Acetex or AT Plastics to disclose information subject to a written
confidentiality agreement with third parties or competitively sensitive
information relating to areas or projects where Acetex and AT Plastics are
competitors. For greater certainty, until the earlier of the Effective Date and
the termination of this Agreement, access to and exchange of competitively
sensitive confidential information ("Confidential Data") as between the Parties
shall be limited to that which is reasonably necessary for the purposes of
securing all necessary regulatory approvals, the preparation and settlement of
definitive documents and the advancement of the Amalgamation as contemplated
herein and shall be further limited such that the dissemination of such
Confidential Data shall be confined to those representatives of the Parties and
their advisors who have a need to know such information for these purposes and
who agree to respect such confidentiality in their dealings with such
Confidential Data. In particular, with reference to access to and the sharing of
Confidential Data of one Party with representatives of the other Party for the
purposes of preparing any filings or submissions under the Competition Act in
respect of the Amalgamation, the general principle which shall be applied is

right, as the case may be. If any such notice is delivered, provided that a
Party is proceeding diligently to cure such matter and such matter is capable of
being cured (except matters arising out of the failure to make appropriate
disclosure in the disclosure memoranda delivered on the date of execution of

Agreement until the later of September 30, 2003 and (except with respect to the
condition set out in 6.3(d)) the expiration of a period of thirty (30) days from

     been made under any of Sections 8.1(a)(i) or (ii) or 8.1(b) above, no
     further payment shall be required under Sections 8.1 (a)(i) or (ii) or
     8.1(b).

8.2      AT PLASTICS COMPENSATION

(a)  If at any time after the execution of this Agreement: Acetex does not waive
     the condition set out in Section 6.3(d) by September 30, 2003 and its
     failure to do so is not principally attributable to the failure of AT
     Plastics to co-operate and assist Acetex with respect to the matters
     provided therein and/or the failure of AT Plastics to perform the AT
     Plastics Support Obligations (an "AT Plastics Payment Event"), then Acetex
     shall pay to AT Plastics US$5,000,000 as liquidated damages in immediately
     available funds to an account designated by AT Plastics within three
     business days thereof or if requested by AT Plastics issue and deliver to
     AT Plastics (subject to all necessary regulatory approvals including the
     approval of the Toronto Stock Exchange) that number of Acetex Shares, as
     fully paid and non-assessable as is equal to US$5,000,000 divided by the
     closing price of the Acetex Shares on the business day immediately
     preceding the Acetex Payment Event, within three business days thereof

(b)  If this Agreement is terminated by AT Plastics in accordance with Section
     9.1(b) in reliance on the condition contained in Section 6.2(a), then
     Acetex shall pay to AT Plastics in immediately available funds the amount
     of US$1,000,000 to an account designated by AT Plastics, within three
     business days thereof issue or if requested by AT Plastics issue and
     deliver to AT Plastics (subject to all necessary regulatory approvals
     including the approval of the Toronto Stock Exchange) that number of Acetex
     Common Shares of its capital, as fully paid and non-assessable as is equal
     to US$1,000,000 divided by the closing price of the Acetex Shares on the
     business day immediately preceding the date of such termination, within
     three business days thereof.

(c)  Notwithstanding anything to the contrary contained herein, if a payment has
     been made under any of Sections 8.2(a)or 8.2(b) above, no further payment
     shall be required under Sections 8.2(a) or 8.2(b).

8.3      LIQUIDATED DAMAGES

         Each Party acknowledges that the amounts set out in this Article 8
represent liquidated damages which are a genuine pre-estimate of the damages,
including opportunity costs, which the Party entitled to such damages will
suffer or incur as a result of the event (subject to Section 6.4) giving rise to
such damages and resultant termination of this Agreement, and are not penalties.
Each Party irrevocably



waives any right it may have to raise as a defence that any such liquidated
damages are excessive or punitive.

8.4      LIMITED REMEDY

         For greater certainty, the Parties agree that the compensation or
damages to be received pursuant to this Article 8 is the sole remedy in
compensation or damages of the party receiving such payment; provided however
that nothing contained in this Article 8 or Section 9.1, including the payment
of an amount under this Article 8 shall relieve or have the effect of relieving
any Party in any way from liability for damages incurred or suffered by a Party
as a result of a breach of this Agreement by a Party acting in bad faith with a
clear intent and design to prevent the conditions precedent to this Agreement's
completion from being satisfied. 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.

6.   DISCLOSURE.

         Acetex has publicly disclosed in documents filed with the Securities
Authorities or disclosed to AT Plastics in writing, on or prior to the date

affects the ability of Acetex to consummate the transactions contemplated
hereby.

consolidated financial condition of Acetex at the respective dates indicated and
the results of operations of Acetex (on a consolidated basis) for the periods
indicated therein (subject, in the case of any unaudited interim financial

8.   BOOKS AND RECORDS.

         The corporate records and minute books of Acetex and the Material
Subsidiaries have been maintained substantially in accordance with all
applicable Laws and are complete and accurate in all material respects.



9.   LITIGATION, ETC.

         Except as set forth or specifically reflected in any document filed
with the Securities Authorities, or as disclosed in writing to AT Plastics on or
prior to the date hereof, there is no claim, action, proceeding or investigation
pending or, to the knowledge of Acetex, threatened against or relating to Acetex
or any Material Subsidiary or affecting any of their properties or assets before
any court or governmental or regulatory authority or body that, if adversely
determined, is likely to have a material adverse effect on Acetex or prevent or
materially delay consummation of the transactions contemplated by this Agreement
or the Amalgamation, nor is Acetex aware of any basis for any such claim,
action, proceeding or investigation. Neither Acetex nor any Material Subsidiary

or the Amalgamation.

10.  ENVIRONMENTAL.

         All operations of Acetex and its Material Subsidiaries, have been and

adverse effect on Acetex. Except as has been disclosed in writing to AT Plastics
on or prior to the date hereof, neither Acetex nor any Material Subsidiary is
aware of, or is subject to:

(a)  any proceeding, application, order or directive which relates to

     applicable to Acetex or any Subsidiary, including, without limitation, any

11.  INSURANCE.

         Policies of insurance in force as of the date hereof naming Acetex as
an insured adequately cover all risks reasonably and prudently foreseeable in
the operation and conduct of the business of Acetex and the Material
Subsidiaries for which, having regard to the nature of such risk and the
relative cost of obtaining insurance, it is in the opinion of Acetex reasonable
to seek such insurance rather than provide for self insurance. All such policies
of insurance shall remain in force and effect (subject to taking into account
insurance market conditions and offerings and industry practices) and shall not
be cancelled or otherwise terminated as a result of the transactions
contemplated hereby or by the Amalgamation other than such cancellations as
would not individually or in the aggregate have a material adverse effect on
Acetex.

12.      TAX MATTERS.

(a)  RETURNS FILED AND TAXES PAID. All Returns required to be filed by or on
     behalf of Acetex or any Material Subsidiaries have been duly filed on a

     on or prior to the date hereof, all Taxes shown to be payable on the
     Returns or on subsequent assessments with respect thereto have been paid



     in full on a timely basis, and no other material amount of Taxes are
     payable by Acetex or any Material Subsidiaries with respect to items or
     periods covered by such Returns.

(b)  TAX RESERVES. Acetex has paid or provided adequate accruals in its
     consolidated financial statements for the year ended December 31, 2002 for

     Canada.

(c)  TAX DEFICIENCIES; AUDITS. Except as has been disclosed in writing to AT
     Plastics, no deficiencies exist or have been asserted with respect to Taxes
     of Acetex or any Material Subsidiary, neither Acetex nor any Material
     Subsidiary is a Party to any action or proceeding for assessment or
     collection of Taxes, nor has such event been asserted or threatened against
     Acetex or any Material Subsidiary or any of their respective assets, except
     where such deficiencies, actions or proceedings are not material to Acetex
     or the Amalgamation.

13.  PENSION AND EMPLOYEE BENEFITS.
