This Time-Vesting Restricted Stock Unit Award Agreement (the “Agreement”) is made and entered into as of <<Grant Date>> (the “Grant Date”), by and between Celanese Corporation, a Delaware corporation (the “Company”), and <<NAME>> (the “Participant”). Capitalized terms used, but not otherwise defined, herein shall have the meanings ascribed to such terms in the Celanese Corporation 2009 Global Incentive Plan (as amended from time to time, the “2009 Plan”).

1.Time-Vesting RSU Award: In order to encourage Participant’s contribution to the successful performance of the Company, the Company hereby grants to Participant as of the Grant Date, pursuant to the terms of the 2009 Plan and this Agreement, an award (the “Award”) of time-vesting Restricted Stock Units (“RSUs”) representing the right to receive an equal number of Common Shares upon vesting. The Participant hereby acknowledges and accepts such Award upon the terms and subject to the conditions, restrictions and limitations contained in this Agreement and the 2009 Plan.

2.    Time-Based Vesting: Subject to Section 4 and Section 7 of this Agreement, «Number_Units» RSUs shall vest on <<vesting 1>>; «Number_Units» RSUs shall vest on <<vesting 2>>; and «Number_Units» RSUs shall vest on <vesting 3>. Each such date shall be referred to as a “Vesting Date”. Each period between the Grant Date and a Vesting Date shall be referred to as a “Vesting Period”.

(a)    Upon the termination of the Participant’s employment by the Company without Cause or due to the Participant’s Retirement, death or Disability, a prorated portion of the RSUs that remain unvested will vest in an amount equal to (i) the unvested RSUs in each Vesting Period multiplied by (ii) a fraction, the numerator of which is the number of complete and partial calendar months from the Grant Date to the date of termination without Cause or due to the Participant’s Retirement, death or Disability, and the denominator of which is the number of complete and partial calendar months in each applicable Vesting Period, such product to be rounded up to the nearest whole number. In any such case , such prorated number of unvested RSUs that vest in accordance with the preceding sentence will be subject to any applicable taxes under Section 8 upon such vesting, , which may be rounded up in each case to avoid fractional shares, and will be settled in accordance with the provisions of Section 5 following the applicable Vesting Date(s).

(b)    To the extent permitted by applicable country, state or province law, as consideration for the vesting provisions upon Retirement contained in Section 5(a), upon Retirement, the Participant shall enter into a departure and general release of claims agreement with the Company that includes two-year noncompetition and non-solicitation covenants in a form acceptable to the Company.

(c)    The remaining unvested portion of the Award shall be immediately forfeited and cancelled without consideration as of the date of the Participant’s termination of employment without Cause or due to the Participant’s Retirement, death or Disability.

(d)    Upon the termination of the Participant’s employment for any other reason, the unvested portion of the Award shall be immediately forfeited and cancelled without consideration as of the date of the Participant’s termination of employment.

5.    Settlement of RSUs: Subject to Sections 4, 7 and 8 of this Agreement, the Company shall deliver to the Participant (or to a Company-designated brokerage firm or plan administrator) as soon as administratively practicable following the applicable Vesting Date (but in no event later than 2 ½ months after the applicable Vesting Date), in complete settlement of all RSUs vesting on such Vesting Date, a number of Common Shares equal to the number of RSUs vesting on such Vesting Date.

6.    Rights as a Stockholder: The Participant shall have no voting, dividend or other rights as a stockholder with respect to the Award until the RSUs have vested and Common Shares have been delivered pursuant to this Agreement

(a)    Notwithstanding any other provision of this Agreement to the contrary, upon the occurrence of a Change in Control with respect to any unvested RSUs granted pursuant to this Agreement that have not previously been forfeited:

(1)    If (i) a Participant’s rights to the unvested portion of the Award are not adversely affected in connection with the Change in Control, or, if adversely affected, a substitute award with an equivalent (or greater) economic value and no less favorable vesting conditions is granted to the Participant upon the occurrence of a Change in Control, and (ii) the Participant’s employment is terminated by the Company (or its successor) without Cause within two years following the Change in Control, then the unvested portion of the Award (or, as applicable, the substitute award) shall immediately vest and a number of Common Shares equal to the number of unvested RSUs shall be delivered to the Participant within thirty (30) days following the date of termination, subject to the provisions of Section 8.

(2)    If a Participant’s right to the unvested portion of the Award is adversely affected in connection with the Change in Control and a substitute award is not made pursuant to Section 7(a)(1) above, then upon the occurrence of a Change in Control, the unvested portion of the Award shall immediately vest and a number of Common Shares equal to the number of unvested RSUs shall be delivered to the Participant within thirty (30) days following the Change in Control, subject to the provisions of Section 8; and

(b)    Notwithstanding any other provision of this Agreement to the contrary, in the event of a corporate dissolution of the Company that is taxed under Section 331 of the Internal Revenue Code of 1986, as amended, then in accordance with Treasury Regulation Section 1.409A-3(j)(4)(ix)(A), this Agreement shall terminate and any RSUs granted pursuant to this Agreement that have not previously been forfeited shall immediately become Common Shares and shall be delivered to the Participant within thirty (30) days following such dissolution.

8.    Income and Other Taxes: The Company shall not deliver Common Shares in respect of any RSUs unless and until the Participant has made arrangements satisfactory to the Committee to satisfy applicable withholding tax obligations for US federal, state, and local income taxes (or the foreign counterpart thereof) and applicable employment taxes. Unless otherwise permitted by the Committee, withholding shall be effected at the minimum statutory rates by withholding RSUs in connection with the

vesting and/or settlement of RSUs. The Participant acknowledges that the Company shall have the right to deduct any taxes required to be withheld by law in connection with the delivery of Common Shares issued in respect of any vested RSUs from any amounts payable by it to the Participant (including, without limitation, future cash wages). The Participant acknowledges and agrees that amounts withheld by the Company for taxes may be less than amounts actually owed for taxes by the Participant in respect of the Award. Any vested RSUs shall be reflected in the Company’s records as issued on the respective dates of issuance set forth in this Agreement, irrespective of whether delivery of such Common Shares is pending the Participant’s satisfaction of his or her withholding tax obligations.

9.    Securities Laws: The Company may impose such restrictions, conditions or limitations as it determines appropriate as to the timing and manner of any resales by the Participant or other subsequent transfers by the Participant of any Common Shares issued as a result of the vesting or settlement of the RSUs, including without limitation (a) restrictions under an insider trading policy, and (b) restrictions as to the use of a specified brokerage firm for such resales or other transfers. Upon the acquisition of any Common Shares pursuant to the vesting or settlement of the RSUs, the Participant will make or enter into such written representations, warranties and agreements as the Company may reasonably request in order to comply with applicable securities laws or with this Agreement and the 2009 Plan. All accounts in which such Common Shares are held or any certificates for Common Shares shall be subject to such stop transfer orders and other restrictions as the Company may deem advisable under the rules, regulations and other requirements of the Securities and Exchange Commission, any stock exchange or quotation system upon which the Common Shares are then listed or quoted, and any applicable federal or state securities law, and the Company may cause a legend or legends to be put on any such certificates (or other appropriate restrictions and/or notations to be associated with any accounts in which such Common Shares are held) to make appropriate reference to such restrictions.

10.    Non-Transferability of Award: The RSUs may not be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by the Participant other than by will or by the laws of descent and distribution, and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company; provided, that the Participant may designate a beneficiary, on a form provided by the Company, to receive any portion of the Award payable hereunder following the Participant’s death.

11.    Other Agreements: Subject to Sections 11(a) and 11(b) of this Agreement, this Agreement and the 2009 Plan constitute the entire understanding between the Participant and the Company regarding the Award, and any prior agreements, commitments or negotiations concerning the Award are superseded.

(a)    The Participant acknowledges that as a condition to the receipt of the Award, the Participant:

(1)    shall have delivered to the Company an executed copy of this Agreement;

(2)    shall be subject to the Company’s stock ownership guidelines;

(3)    shall be subject to policies and agreements adopted by the Company from time to time, and applicable laws and regulations, requiring the repayment by the Participant of incentive compensation under certain circumstances, without any further act or deed or consent of the Participant; and

(4)    shall have delivered to the Company an executed copy of the Long-Term Incentive Claw-Back Agreement (if a current version of such Long-Term Incentive Claw-Back Agreement is not already on file, as determined by the Committee in its sole discretion). For purposes hereof, “Long-Term Incentive Claw-Back Agreement” means

an agreement between the Company and the Participant associated with the grant of long-term incentives of the Company, which contains terms, conditions, restrictions and provisions regarding one or more of (i) noncompetition by the Participant with the Company, and its customers and clients; (ii) nonsolicitation and non-hiring by the Participant of the Company’s employees, former employees or consultants; (iii) maintenance of confidentiality of the Company’s and/or clients’ information, including intellectual property; (iv) nondisparagement of the Company; and (v) such other matters deemed necessary, desirable or appropriate by the Company for such an agreement in view of the rights and benefits conveyed in connection with an award.

(b)    If the Participant is a non-resident of the U.S., there may be an addendum containing special terms and conditions applicable to awards in the Participant’s country. The issuance of the Award to any such Participant is contingent upon the Participant executing and returning any such addendum in the manner directed by the Company.

12.    Not a Contract for Employment; No Acquired Rights; Agreement Changes: Nothing in the 2009 Plan, this Agreement or any other instrument executed in connection with the Award shall confer upon the Participant any right to continue in the Company's employ or service nor limit in any way the Company's right to terminate the Participant's employment at any time for any reason. The grant of RSUs hereunder, and any future grant of awards to the Participant under the 2009 Plan, is entirely voluntary and at the complete and sole discretion of the Company. Neither the grant of these RSUs nor any future grant of awards by the Company shall be deemed to create any obligation to grant any further awards, whether or not such a reservation is expressly stated at the time of such grants. The Company has the right, at any time and for any reason, to amend, suspend or terminate the 2009 Plan; provided, however, that no such amendment, suspension, or termination shall adversely affect the Participant’s rights hereunder.

13.    Severability: In the event that any provision of this Agreement is declared to be illegal, invalid or otherwise unenforceable by a court of competent jurisdiction, such provision shall be reformed, if possible, to the extent necessary to render it legal, valid and enforceable, or otherwise deleted, and the remainder of this Agreement shall not be affected except to the extent necessary to reform or delete such illegal, invalid or unenforceable provision.
