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 and Restated April 19, 2012 (as amended from time to time, the “2009 Plan”).

1.Time-Based RSU Award: The Company hereby grants to the Participant, pursuant to the terms of the 2009 Plan and this Agreement, an award (the “Award”) of <<# Units>> Restricted Stock Units (the “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.    Vesting of Restricted Stock Units:

(a)    Normal Vesting. Subject to Sections 2(b) and 2(c) below, the RSUs shall vest on the first anniversary of the Grant Date (the “Vesting Date”).

(b)    Change in Control. Notwithstanding any other provision of this Agreement to the contrary, upon the occurrence of a Change in Control, the RSUs, to the extent not previously forfeited or canceled, shall immediately vest and a number of Common Shares equal to such RSUs shall be delivered to the Participant within thirty (30) days of the occurrence of such Change in Control.

(c)    Termination of Service.

(i)    Upon the termination of the Participant’s service with the Company as a director due to the Participant’s death or Disability, a prorated portion of RSUs will vest in an amount equal to (A) the number of unvested RSUs multiplied by (B) a fraction, the numerator of which is the number of complete calendar months that have transpired from the Grant Date to the date of termination, and the denominator of which is the number of complete calendar months in the vesting period, such product to be rounded up to the nearest whole number. The prorated number of RSUs shall vest and a number of Common Shares equal to such prorated number of RSUs shall be delivered to the Participant within thirty (30) days following the applicable Vesting Date. The remaining portion of the Award shall be forfeited and cancelled without consideration.

3.    Settlement of RSUs: Subject to Section 2 of this Agreement, and except to the extent the Participant has elected that delivery be deferred in accordance with the rules and procedures prescribed by the Board or Compensation Committee (which rules and procedures, among other things, shall be consistent with the requirements of Section 409A of the Code), the Company shall deliver to the Participant (or to a Company-designated brokerage account) as soon as administratively practicable following the Vesting Date (but in no event later than 2 ½ months after the Vesting Date), in complete settlement of all vested RSUs, a number of Common Shares equal to the number of vested RSUs that have not previously been settled.

5.    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.

6.    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.
