    This Performance-Vesting RSU Award
Agreement (hereinafter called the “Agreement”) is made and entered into
effective as of [Grant Date] (the “Grant Date”) by and between Celanese
Corporation, a Delaware corporation (“Celanese” or the “Company”) and
[Participant Name] (the “Participant”), when fully executed thereby in
accordance with this Agreement.  Except as defined herein, capitalized
terms shall have the same meaning ascribed to them under the Celanese
Corporation 2004 Stock Incentive Plan (the “Plan”), as amended from time to
time.  To the extent that any provision of this Agreement conflicts
with the express terms of the Plan, it is hereby acknowledged and agreed that
the terms of this Agreement shall control with respect to this
Award.

     

    1. Performance
RSU Award:  In order to encourage Participant’s contribution to
the successful performance of the Company, Celanese hereby grants to Participant
as of the Grant Date, pursuant to the terms of the Plan and this Agreement, a
performance-vesting RSU award (the “Performance RSUs” or “Award”) representing
the right to acquire shares of the Company’s Series A Common Stock (“Common
Stock”).  The number of shares that may become Vested Stock under this
Award is set forth in Appendix A.  Participant hereby acknowledges and
accepts such Award upon such terms and subject to such performance requirements
and other conditions, restrictions and limitations contained in this Agreement
and the Plan.

     

    2. Performance-Based
Vesting:  The number of Performance RSUs that may vest and be
issuable as Common Stock based on Company performance shall be determined using
the methodology set forth in Appendix A and Appendix B, and shall be subject to
the following provisions.

     

    (a) Service Period: The Service
Period shall be the period commencing on [Grant Date] and ending on October 14,
2011.

     

    (b) Performance
Measures:  Performance vesting shall be based on achievement
against pre-determined targets for i) Operating EBITDA and ii) Relative Total
Shareholder Return (“Relative TSR”).  These measures are described in,
and will be determined in accordance with, Appendix A.

     

    (c) Performance
Targets:  Threshold, Target and Stretch performance levels for
each performance measure for the performance period are described in Appendix
A.

     

    (d) Performance
Vesting:  The aggregate number of restricted stock units that
may actually vest shall be determined by reference to the target number of
Performance RSUs granted pursuant to the Award as adjusted for the Company’s
level of performance with respect to each performance measure as set forth in
Appendix A.

     

    (e) Vesting Date:  The date upon
which any restricted stock units that may vest pursuant to this Award shall be
October 14, 2011 (the “Vesting Date”) so long as the New York Stock Exchange
shall be open for trading on such date (or on the preceding trading day if there
shall have been no trading on the Vesting Date).

     

    3. Effects
of Certain Events:

     

    (a) Upon the
death of the Participant or the termination of the Participant’s employment with
the Company by reason of Total Disability, Performance RSUs in an amount equal
to (i) the Target number of Performance RSUs granted hereby multiplied by (ii) a
fraction, the numerator of which is the number of complete calendar months
between the Grant Date and the date of death or such termination, and the
denominator of which is thirty-four, such product to be rounded up to the
nearest whole number (the “Prorated Amount”), shall immediately become Vested
Stock and shall be delivered to the Participant within thirty (30) days after
the Participant’s death or Date of Termination (provided that if the
payment is by reason of termination due to Total Disability and the Participant
is a Specified Employee on the Date of Termination, payment shall not be made
until six (6) months and one day after the Participant’s Date of
Termination).

    5. Rights as
a Stockholder:  The Participant shall have no rights as a
stockholder with respect to the Award.

     

    6. Change in
Control; Dissolution:

     

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

    (i) If the
unvested Award is assumed by the Participant’s new employer in connection with
the Change in Control, or a substitute award with the equivalent (or greater)
economic value and no less favorable vesting conditions is put in place
effective upon the Change in Control, the Award (or as applicable, the
substitute award) shall continue to be subject to the vesting and payment
conditions provided herein, provided that if the Participant’s employment is
terminated without Cause following the Change in Control, Performance RSUs in an
amount equal to the Target number of Performance RSUs granted hereby shall
immediately vest and shall be delivered in full within thirty (30) days after
the Participant’s Date of Termination provided that if the Participant is a
Specified Employee on the Date of Termination, delivery shall not be made until
six (6) months and one day after the Participant’s Date of

Control occurs.

     

    (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

    7. Income
Taxes: The Company shall not deliver shares in respect of any
Performance RSUs unless and until the Participant has made arrangements
satisfactory to the Committee to satisfy applicable withholding tax
obligations.  Unless otherwise permitted by the Committee, withholding
shall be effected by withholding Common Stock issuable in connection with the
delivery of Performance 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 Stock issued in respect of any vested
Performance RSUs from any amounts payable by it to the Participant (including,
without limitation, future cash wages).  Any vested Performance 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
shares is pending the Participant’s satisfaction of his or her withholding tax
obligations.

     

    8. Non-Transferability
of Award:  The Participant represents and warrants that the
Performance RSUs are being acquired by the Participant solely for the
Participant’s own account for investment and not with a view to or for sale in
connection with any distribution thereof.  The Participant further
understands, acknowledges and agrees that, except as otherwise provided in the
Plan, the Performance RSUs may not be sold, assigned, transferred, pledged or
otherwise directly or indirectly encumbered or disposed of except to the extent
expressly permitted hereby and at all times in compliance with the U.S.
Securities Act of 1933, as amended, and the rules and regulations of the
Securities and Exchange Commission thereunder, and in compliance with applicable
state securities or “blue sky” laws and non-U.S. securities
laws.  Unless permitted by the Committee, the Performance RSUs may not
be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated
by the Participant other than by will or the laws of descent and
distribution.  Notwithstanding the foregoing, the Participant may
designate a beneficiary on a form provided by the Company, with such beneficiary
to receive any Common Stock issued hereunder following the Participant’s
death.

     

    9. Other

conditions and provisions regarding one or more of (i) competition by the

Company’s and/or clients’ information; and (iii) 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 the Award.

     

    (b) The Award
(including the terms described herein) is subject to the provisions of the Plan
and, if the Participant is outside the U.S., there may be an addendum containing
special terms and conditions applicable to awards in the Participant’s
country.  The award of Performance RSUs to any such participant is
contingent upon the Participant executing and returning any such addendum in the
manner directed by the Company.

     

    (c) The
issuance of shares provided by this Agreement is subject to the restrictions in
Section 17 below and is made in reliance on the provision in Treasury Regulation
Section 1.409A-3(b) permitting distribution on the earlier of the Vesting Date,
a separation from service or a Change in Control as provided under this

right to terminate the Participant’s employment or other service at any time for
any reason.

    Performance-Based
Vesting Calculation

     

    The
percentage of Performance RSUs that may vest on October 14, 2011 is subject to
the achievement of specified levels of (i) the Company’s Operating EBITDA during
its 2009 and 2010 fiscal years and (ii) the Company’s Total Shareholder Return
as compared with peer companies during the TSR Performance Period, where the
potential performance-based vesting outcomes are summarized as

              The
      Operating EBITDA performance percentage for each measurement period shall
      be calculated by straight-line interpolation for results achieved between
      Threshold and Target, or for results achieved between Target and
      Stretch;

            

    

     

    
      	
              2.  

            	
              For
      each measurement period, the result of step 1 (a percentage) shall be

  RSUs;

              Determine
      the Threshold, Target and Stretch Performance Levels for the Peer Group
      (excluding the Company) using a rank-based methodology as
      follows:

            

    

     

    N = the
number of companies that remain in the Peer Group on September 30,
2011

    Target Performance Level = .5
(N+1)

     

    Stretch Performance Level =

    If any
Performance Level does not correspond exactly to a company in the Peer Group
ranking, then the company that corresponds most closely to the specific
performance level (whether higher or lower) shall represent such Performance
Level.

Stock”).  The number of units that may vest and become payable as cash
under this Award is set forth in Appendix A.  Participant hereby
acknowledges and accepts such Award upon such terms and subject to such
performance requirements and other conditions, restrictions and limitations
contained in this Agreement.

    

    2. Performance-Based

Period shall be the period commencing on December 11, 2008 and ending on October
14, 2011.

    

    (b) Performance

against pre-determined targets for i) Operating EBITDA and ii) Relative Total
Shareholder Return (“Relative TSR”).  These measures are described in,
and will be determined in accordance with, Appendix A.

    

    (c) Performance
Targets:  Threshold, Target and Stretch performance levels for
each performance measure for the performance period are described in Appendix
A.

    

    (d) Performance
Vesting:  The aggregate number of performance units that may
actually vest shall be determined by reference to the target number of
Performance Units granted pursuant to the Award as adjusted for the Company’s
level of performance with respect to each performance measure as set forth in
Appendix A.

    

    (e) Vesting Date:  The date upon
which any performance units that may vest pursuant to this Award shall be

    3. Effects
of Certain Events:

    

    (a) Upon the
death of the Participant or the termination of the Participant’s employment with
the Company by reason of Total Disability, an amount equal to (i) the Target
number of Performance Units granted hereby multiplied by (ii) a fraction, the
numerator of which is the number of complete calendar months between the Grant
Date and the date of  death or such termination, and the denominator
of which is thirty-four, such product to be rounded up to the nearest whole
number (the “Prorated Amount”), shall immediately vest and be payable in cash to
the Participant within thirty (30) days after the Participant’s death or Date of
Termination (provided that if the payment is by reason of termination due to
Total Disability and the Participant is a Specified Employee on the Date of
Termination, payment shall not be made until six (6) months and one day after
the Participant’s Date of Termination).

Committee in its sole discretion.

    

    (b) If the
Committee determines to convert all or any portion of this Award, the provisions

and the Company at the time of conversion.

an amount equal to the Target number of Performance Units granted hereby shall

the Participant’s employment or other service at any time for any
reason.

    

    12. Severability:  In

Agreement shall not be affected except to the extent necessary to reform or
delete such illegal, invalid or unenforceable provision.

    Performance-Based
Vesting Calculation

     

    The
percentage of Performance Units that may vest on October 14, 2011 is subject to
the achievement of specified levels of (i) the Company’s Operating EBITDA during
its 2009 and 2010 fiscal years and (ii) the Company’s Total Shareholder Return
as compared with peer companies during the TSR Performance Period, where the
potential performance-based vesting outcomes are summarized as

Operating EBITDA performance percentage will be earned (0%) if the actual
performance results achieved are below threshold for each respective measurement
period.

    

    The
Participant’s Performance Unit Target Award will be adjusted (up or down) based
on the Company’s absolute achievement of the Operating EBITDA performance goals
as follows:

     

    
      	
              1.  

            	
              The
      Operating EBITDA performance percentage for each measurement period shall
      be calculated by straight-line interpolation for results achieved between
      Threshold and Target, or for results achieved between Target and
      Stretch;

            

    

     

    
      	
              2.  

            	
              For
      each measurement period, the result of step 1 (a percentage) shall be
      multiplied by the Target number of Performance
  Units;

            

    

     

    
      	
              3.  

            	
              The
      results of step 2 for each measurement period shall be added together to
      determine the total number of Operating EBITDA adjusted Units (“Adjusted
      Units”).

              Calculating
      the Award
      Adjustment based on the Relative TSR Results
    Achieved

            

    

     

     

    Relative
TSR performance will be calculated after the end of the TSR Performance
Period.  The resulting calculation will increase or decrease the
number of Adjusted Units by a percentage between 50% and 150%.

              1.  

            	
              Calculate
      Total Shareholder Return for each company in the Peer Group (as set forth
      on Appendix B) for the TSR Performance Period and rank such companies from
      lowest to highest as measured by
TSR.

            

    

     

    
      	
              2.  

            	
              Determine
      the Threshold, Target and Stretch Performance Levels for the Peer Group
      (excluding the Company) using a rank-based methodology as
      follows:

            

    

     

    N = the
number of companies that remain in the Peer Group on September 30,
2011

     

    Threshold Performance Level =
..2 (N+1)

     

    Target Performance Level = .5
(N+1)

     

    Stretch Performance Level =
..8 (N+1)

     

    If any
Performance Level does not correspond exactly to a company in the Peer Group
ranking, then the company that corresponds most closely to the specific
performance level (whether higher or lower) shall represent such Performance
Level.
