                        PIONEER NATURAL RESOURCES COMPANY
                          2006 LONG TERM INCENTIVE PLAN
                        PERFORMANCE UNIT AWARD AGREEMENT

                              (INSERT DATE OF GRANT)

     To: _______________________________

     Pioneer Natural Resources Company, a Delaware  corporation (the "Company"),
is pleased  to grant you an award (the  "Award")  to  receive  an  aggregate  of
__________  performance  units (each,  a  "Performance  Unit") in respect of the
period  January 1, 2007 through  December 31, 2009 (the  "Performance  Period").
This award is subject to your  acceptance of and agreement to all the applicable
terms,  conditions and  restrictions  described in this  Performance  Unit Award
Agreement (the  "Agreement") and the Pioneer Natural Resources Company 2006 Long
Term Incentive Plan (as it may be amended from time to time, the "Plan"). A copy
of the Plan is available upon request.  Except as provided  below, to the extent
that any provision of this  Agreement  conflicts  with the expressly  applicable
terms of the Plan, you  acknowledge and agree that those terms of the Plan shall
control and, if necessary,  the applicable provisions of this Agreement shall be
deemed amended so as to carry out the purpose and intent of the Plan. Terms that
have their initial letters  capitalized,  but that are not otherwise  defined in
this  Agreement,  shall have the meanings given to them in the Plan in effect as
of the date of this Agreement.

     This  Agreement  sets forth the terms of the agreement  between you and the
Company with respect to the Performance Units. By accepting this Agreement,  you
agree to be bound by all of the terms hereof.

     1.   Overview of Performance Units.

     (a)  Performance  Units  Generally.  Each  Performance  Unit  represents  a
contractual  right to  receive  one share of the  Company's  common  stock  (the
"Common Stock"), subject to the terms and conditions of this Agreement; provided
that, based on the relative  achievement against each Performance  Objective (as
defined  below),  the number of shares of Common  Stock that may be  deliverable
hereunder in respect of the  Performance  Units may range from 0% to 250% of the
number of  Performance  Units  stated in the  preamble to this  Agreement  (such
stated number of Performance  Units  hereafter  called the "Initial  Performance
Units").  Your right to receive Common Stock in respect of Performance  Units is
generally  contingent,  in  whole or in part,  upon (i) the  achievement  of the
performance objective outlined in Section 2 below (the "Performance  Objective")
and (ii) except as provided in Section 4 or Section 5, your continued employment
with the Company or one of its  Subsidiaries  through the end of the Performance
Period.



     (b)  Dividend  Equivalents.  With respect to each  outstanding  Performance
Unit,  the Company shall credit a book entry account with an amount equal to the
amount  of any cash  dividend  paid on one  share of Common  Stock.  The  amount
credited to such book entry  account shall be payable to you at the same time or
times,  and subject to the same terms and  conditions as are applicable to, your
Performance  Units;  provided that, if more than the Initial  Performance  Units
shall become  payable in  accordance  with this  Agreement,  the maximum  amount
payable in respect of such dividend  equivalents shall be the amount credited to
your book entry  account.  Dividends and  distributions  payable on Common Stock
other than in cash will be addressed in accordance with Section 8 hereof.

     2. Total  Shareholder  Return  Objective.  The  Performance  Objective with
respect to the Initial  Performance Units is based on Total Shareholder  Return.
Total  Shareholder  Return  shall  mean,  as to the Company and each of the Peer
Companies (as defined below), the annualized rate of return shareholders receive
through stock price changes and the assumed  reinvestment of dividends paid over
the Performance Period.  Dividends per share paid other than in the form of cash
shall have a value equal to the amount of such dividends  reported by the issuer
to its  shareholders  for purposes of Federal income  taxation.  For purposes of
determining  the Total  Shareholder  Return for the Company and each of the Peer
Companies,  the  change in the price of the  Company's  Common  Stock and of the
common stock of each Peer  Company,  as the case may be, shall be based upon the
average of the closing stock prices of the Company and such Peer Company on each
trading  day in the 60-day  period  preceding  each of the start  (the  "Initial
Value") and the end (the "Closing Value") of the Performance Period. The Initial
Value of the Common Stock to be used to determine Total Shareholder  Return over
the  Performance  Period is $41.78 per share.  Achievement  with respect to this
Performance  Objective  shall  be  determined  based on the  Company's  relative
ranking in respect of the  Performance  Period with regard to Total  Shareholder
Return as compared to Total Shareholder Return of the Peer Companies,  and shall
be determined in accordance with the applicable table as set forth in Appendix A
hereto.  The  applicable  table shall be determined  based on the number of Peer
Companies for the Performance  Period. A company shall be a "Peer Company" if it
(i) is one of the companies  listed on Appendix A hereto and (ii) has a class of
common equity  securities  listed to trade under Section 12(g) of the Securities
Exchange  Act of 1934,  as amended  (the  "1934  Act"),  during  each day of the
Performance  Period. The number of Performance  Units, if any,  determined to be
earned  pursuant to the  applicable  table under Appendix A shall be referred to
"Earned Performance Units".

     3. Conversion of Performance Units;  Delivery of Performance Units.  Unless
an earlier date  applies  pursuant to Section  4(a),  Section 5(c) or Section 6,
payment  in  respect of Earned  Performance  Units  shall be made not later than
March 15 of the year  following the year in which the  Performance  Period ends.
Unless otherwise determined by the Committee,  all payments in respect of Earned
Performance Units shall be made in freely  transferable  shares of Common Stock;
provided,  however,  that if and to the extent that the reservation of the power
to settle (as opposed to the act of settling)  Performance Units in cash instead
of shares  would result in an  additional  financial  accounting  charge for the
Company, the Committee shall not have the right to settle such Performance Units
other than in the form of Common Stock (or, if applicable,  stock of a Successor
Corporation  (as defined in Section  5)).  Neither this Section 3 nor any action
taken  pursuant to or in  accordance  with this  Section 3 shall be construed to
create a trust of any kind. Any shares of Common Stock issued to you pursuant to
this Agreement in settlement of



Earned  Performance  Units shall be in book entry form  registered in your name.
Any fractional Earned Performance Units shall be rounded up to the nearest whole
share of Common Stock.

     4.  Termination of Employment.

     (a) Death or Disability. In the event that your employment with the Company
or a Subsidiary  terminates  during the Performance  Period due to your death or
Disability (as such term is defined in the Severance  Agreement  between you and
the  Company or one of its  subsidiaries),  you shall be deemed to have earned a
number of Performance  Units equal to the product of (i) and (ii), where (i) and
(ii) are:


     (i)   the Initial Performance Units;


     (ii)  a fraction (the "Pro-Ration Fraction"), (A) the numerator of which is
           the  number  of  full  months  (counting  the  month  in  which  your
           termination  of  employment  occurs  as  a  full  month)  during  the
           Performance  Period  during  which  you  were  employed  and  (B) the
           denominator of which is 36.


Distribution  of shares of Common  Stock in  respect  of the  Performance  Units
determined  to be earned by reason of this  Section 4(a) shall be made not later
than 75 days  following  your  death  or  Disability  and  shall  be in full and
complete  satisfaction  of all of your  rights (and the rights of any person who
derives his, her or its rights from you) under this Agreement.

     (b) Normal  Retirement.  In the event that your employment with the Company
and each of its  Subsidiaries  by which you are employed  terminates  during the
Performance  Period due to your  retirement at or after having  attained age 60,
you shall be deemed to have  earned,  as of the end of the  Performance  Period,
that  number of  Performance  Units  equal to the  product  of (i) the number of
Earned Performance Units that you would have earned in accordance with Section 2
had you remained  employed through the end of the Performance  Period multiplied
by (ii) the  Pro-Ration  Fraction.  Any  portion of the  Performance  Units that
cannot become earned and payable in accordance with the preceding sentence shall
terminate and  automatically  be cancelled as of the date of your termination of
employment.  Any portion of your Performance Units that is eligible to be earned
pursuant to first sentence of this subparagraph (b), but is not earned as of the
end of  the  Performance  Period,  shall  terminate  and be  canceled  upon  the
expiration of such Performance Period.

     (c) Termination  Without Cause or Termination For Good Reason. In the event
that your employment with the Company and each of its  Subsidiaries by which you
are employed is terminated during the Performance  Period (x) by the Company and
such  Subsidiaries and such termination is not a Termination for Cause or (y) by
you and such  termination is a Termination for Good Reason (as each such term is
defined in the  Severance  Agreement  between  you and the Company or one of its
subsidiaries),  then  notwithstanding  the terms of any such Severance Agreement
you shall be deemed to have earned, as of the end of the Performance Period, the
number of Earned Performance Units that you would have earned in accordance with
Section 2 had you remained  employed through the end of the Performance  Period.
Any portion of your Performance  Units that is eligible to be earned pursuant to
the  preceding  sentence,  but is not



earned as of the end of the Performance Period,  shall terminate and be canceled
upon the expiration of such Performance Period.

     (d) Other  Termination of Employment.  Unless  otherwise  determined by the
Committee at or after grant,  in the event that your employment with the Company
or a Subsidiary  terminates  prior to the end of the Performance  Period for any
reason  other  than  those  listed in Section  4(a),  4(b) or 4(c),  all of your
Performance  Units shall  terminate  and  automatically  be  canceled  upon such
termination of employment.

     5. Change of Control.  Notwithstanding  the provisions of Section 1 through
Section 4 hereof or the terms of any Change of Control Agreement between you and
the Company or a Subsidiary (a "CIC  Agreement"),  if you have been continuously
employed  from the grant  specified  above  until  the date  that the  Change of
Control occurs (the "Change of Control  Date") or you are treated,  for purposes
of such CIC  Agreement,  to have  remained in  employment  through the Change of
Control Date,  upon the occurrence of a Change of Control your rights in respect
of the  Performance  Units shall be  determined  as provided in Section 5(a). If
your employment  shall have terminated  prior to the Change of Control Date, but
at least some of your Performance Units remain  outstanding  pursuant to Section
4(b) or Section  4(c),  your rights in respect of your  outstanding  Performance
Units shall be determined as provided in Section 5(b).

     (a) If a Change of Control occurs, you will be issued a number of shares of
Common  Stock  equal to the number of  Performance  Units that would have become
Earned Performance Units in accordance with the provisions of Section 2 assuming
that:


     (i)  the Performance Period ended on the Change of Control Date and


     (ii) the  determination of  whether, and  to what  extent, the  Performance
          Objective  is achieved, is  based on  actual  performance  against the
          stated performance criteria through the Change of Control Date.

     (b) If your employment  terminated prior to the Change of Control Date, but
some or all of  your  Performance  Units  are  still  outstanding  on such  date
pursuant to Section 4(b) or 4(c),  then, you shall receive a number of shares of
Common  Stock equal to the  product of (A) the number of shares of Common  Stock
that would have been issued to you in respect to the Initial  Performance Units,
determined as though Section 5(a) was applicable to you times (B) the Pro-Ration
Fraction.

     (c) Any shares of Common Stock issuable pursuant to this Section 5 shall be
issued  immediately  following  (and not later  than) 5 business  days after the
Change of Control Date and shall be fully earned and freely  transferable  as of
the date of the Change of Control.  Notwithstanding  anything else  contained in
this  Section 5 to the  contrary,  if the Change of  Control  involves a merger,
reclassification,  reorganization or other similar transaction pursuant to which
the Common Stock is exchanged  for stock of the  surviving  corporation  in such
merger,  the successor to the  corporation  or the direct or indirect  parent of
such a corporation (collectively,  the "Successor Corporation"),  then you shall
receive,  instead of each share of Common Stock otherwise deliverable hereunder,
the same  consideration  (whether  stock,  cash or other  property)  payable  or
distributable  in such  transaction  in respect of a share of Common



Stock. Any property distributed pursuant to this Section 5(c), whether in shares
of the  Successor  Corporation  or  otherwise,  shall  in all  cases  be  freely
transferable  without any restriction  (other than any such restriction that may
be imposed at applicable  law), and any  securities  issued  hereunder  shall be
registered to trade under the 1934 Act, and shall have been registered under the
Securities Act of 1933, as amended (the "1933 Act").

     (d)  Notwithstanding  anything  else  contained  in this  Section  5 to the
contrary,  the Committee may elect, at its sole discretion by resolution adopted
prior to the Change of Control  Date,  to satisfy  your rights in respect of the
Performance  Units (as determined  pursuant to the foregoing  provisions of this
Section  5),  in whole or in part,  by  making a cash  payment  to you  within 5
business  days of the Change of Control Date in respect of all such  Performance
Units  or  such  portion  of  such  Performance  Units  as the  Committee  shall
determine.  Any cash payment for any Performance Unit shall be equal to the Fair
Market  Value of the  number  of  shares of  Common  Stock  into  which it would
convert, determined on the Change of Control Date.

     6.  Nontransferability  of Awards.  The Performance Units granted hereunder
may  not be  sold,  transferred,  pledged,  assigned,  encumbered  or  otherwise
alienated  or  hypothecated,  other than by will or by the laws of  descent  and
distribution.  Following your death, any shares  distributable (or cash payable)
in respect of Performance Units will be delivered or paid, at the time specified
in Section 3 or, if applicable,  Section 4 or Section 5, to your  beneficiary in
accordance  with,  and  subject to, the terms and  conditions  hereof and of the
Plan.

     7. Beneficiary Designation.  You may from time to time name any beneficiary
or beneficiaries  (who may be named  contingently or successively) to whom shall
be delivered or paid under this  Agreement  following your death any shares that
are distributable or cash payable hereunder in respect of your Performance Units
at the time  specified in Section 3 or, if  applicable,  Section 4 or Section 5.
Each  designation  will  revoke  all  prior  designations,  shall  be in a  form
prescribed by the  Committee,  and will be effective  only when filed in writing
with the Committee  during your  lifetime.  In the absence of any such effective
designation, shares issuable in connection with your death shall be paid by your
surviving spouse, if any, or otherwise to your estate.

     8. Adjustments in Respect of Performance  Units. In the event of any common
stock  dividend or common  stock  split,  recapitalization  (including,  but not
limited to, the payment of an extraordinary  dividend),  merger,  consolidation,
combination,  spin-off,  distribution of assets to stockholders (other than cash
dividends), exchange of shares, or other similar corporate change with regard to
the Company or any Peer Company,  appropriate  adjustments  shall be made by the
Committee to the Initial Value of the  corresponding  common stock,  and, if any
such event  occurs  with  respect to the  Company,  in the  aggregate  number of
Performance Units subject to this Agreement. The Committee's  determination with
respect to any such  adjustment  shall be  conclusive.

     9. Effect of Settlement.  Upon  conversion  into shares of Common Stock (or
Successor  Corporation  common stock) pursuant to Section 3 or Section 5, a cash
settlement  of  your  rights,  at the  election  of the  Committee  at its  sole
discretion  pursuant  to  Section 3 or Section  5(d),  or a  combination  of the
issuance  of  Common  Stock  and the  payment  of cash in  accordance  with  any
applicable provisions of this  Agreement, all of your  Performance Units subject
to the



Award shall be cancelled and terminated. If and to the extent that you are still
employed  at the end of the  Performance  Period,  and none of your  Performance
Units shall have become earned in accordance  with the terms of this  Agreement,
all  such  Performance  Units  subject  to the  Award  shall  be  cancelled  and
terminated.

     10.  Furnish  Information.   You  agree  to  furnish  to  the  Company  all
information  requested by the Company to enable it to comply with any  reporting
or other  requirements  imposed  upon the  Company  by or under  any  applicable
statute or regulation.

     11.  Remedies.  The parties to this Agreement  shall be entitled to recover
from each other  reasonable  attorneys'  fees  incurred in  connection  with the
enforcement of the terms and  provisions of this Agreement  whether by an action
to enforce specific performance or for damages for its breach or otherwise.

     12. Information Confidential.  As partial consideration for the granting of
the Award  hereunder,  you  hereby  agree  with the  Company  that you will keep
confidential all information and knowledge, except that which has been disclosed
in any public  filings  required by law, that you have relating to the terms and
conditions of this Agreement;  provided,  however,  that such information may be
disclosed as required by law and may be given in confidence to your spouse,  tax
and financial  advisors,  or to a financial  institution to the extent that such
information  is  necessary  to secure a loan.  In the  event any  breach of this
promise comes to the attention of the Company,  it shall take into consideration
that breach in determining  whether to recommend the grant of any future similar
award to you, as a factor  militating  against the  advisability of granting any
such future award to you.

     13. Payment of Taxes.  The Company may from time to time require you to pay
to the  Company  (or  the  Company's  Subsidiary  if you  are an  employee  of a
Subsidiary  of the  Company)  the amount that the  Company  deems  necessary  to
satisfy  the  Company's  or its  Subsidiary's  current or future  obligation  to
withhold  federal,  state or local  income  or other  taxes  that you incur as a
result of the  Award.  With  respect to any  required  tax  withholding,  unless
another  arrangement is permitted by the Company in its discretion,  the Company
shall withhold from the shares of Common Stock to be issued to you the number of
shares  necessary to satisfy the Company's  obligation to withhold  taxes,  that
determination  to be based on the shares' Fair Market  Value,  as defined in the
Plan,  at the time as of which  such  determination  is made.  In the  event the
Company subsequently determines that the aggregate Fair Market Value, as defined
in the Plan,  of any  shares of Common  Stock  withheld  as  payment  of any tax
withholding  obligation  is  insufficient  to  discharge  that  tax  withholding
obligation,  then you shall pay to the Company,  immediately  upon the Company's
request, the amount of that deficiency.

     14. Right of the Company and Subsidiaries to Terminate Employment.  Nothing
contained in this  Agreement  shall confer upon you the right to continue in the
employ of the Company or any Subsidiary of the Company,  or interfere in any way
with the rights of the Company or any  Subsidiary  of the  Company to  terminate
your employment at any time.

     15. No Liability for Good Faith Determinations. Neither the Company nor the
members of the Board and the Committee shall be liable for any act,  omission or
determination



taken or made in good faith with respect to this  Agreement  or the  Performance
Units granted hereunder.

     16. No Guarantee of  Interests.  The Board and the Company do not guarantee
the Common Stock of the Company from loss or depreciation.

     17. Company Records.  Records of the Company or its Subsidiaries  regarding
your period of employment,  termination  of employment and the reason  therefor,
leaves of absence, re-employment,  and other matters shall be conclusive for all
purposes hereunder, unless determined by the Company to be incorrect.

     18. Severability.  If any provision of this Agreement is held to be illegal
or invalid for any reason,  the  illegality or  invalidity  shall not affect the
remaining  provisions  hereof,  but such provision  shall be fully severable and
this  Agreement  shall be  construed  and  enforced as if the illegal or invalid
provision had never been included herein.

     19. Notices.  Whenever any notice is required or permitted hereunder,  such
notice must be in writing and  personally  delivered  or sent by mail.  Any such
notice  required or permitted to be  delivered  hereunder  shall be deemed to be
delivered on the date on which it is personally delivered,  or, whether actually
received or not, on the third  Business  Day after it is deposited in the United
States mail, certified or registered,  postage prepaid,  addressed to the person
who is to receive it at the address which such person has theretofore  specified
by written  notice  delivered  in  accordance  herewith.  The Company or you may
change,  at any time and from time to time, by written notice to the other,  the
address which it or he had previously specified for receiving notices.

     The Company and you agree that any notices shall be given to the Company or
to you at the following addresses:

     Company:      Pioneer Natural Resources Company
                   Attn:  Corporate Secretary

     Holder:       At your current address as shown in the Company's records.

     20.  Waiver of Notice.  Any person  entitled to notice  hereunder may waive

     21.  Successor.  This  Agreement  shall be  binding  upon you,  your  legal
representatives,  heirs,  legatees and distributees,  and upon the Company,  its
successors and assigns.

     22.  Headings  The  titles  and  headings  of  Sections  are  included  for
convenience  of reference only and are not to be considered in  construction  of
the provisions hereof.



     23. Governing Law. All questions  arising with respect to the provisions of
this  Agreement  shall be determined by  application of the laws of the State of
Delaware  except to the extent  Delaware  law is  preempted  by federal law. The
obligation of the Company to sell and deliver Common Stock  hereunder is subject
to applicable laws and to the approval of any governmental authority required in
connection with the  authorization,  issuance,  sale, or delivery of such Common
Stock.

     24. Execution of Receipts and Releases. Any payment of cash or any issuance
or transfer of shares of Common Stock or other property to you, or to your legal
representative,  heir, legatee or distributee, in accordance with the provisions
hereof,  shall, to the extent thereof,  be in full satisfaction of all claims of
such   Persons   hereunder.   The   Company   may  require  you  or  your  legal
representative,  heir, legatee or distributee,  as a condition precedent to such
payment or issuance,  to execute a release and receipt  therefor in such form as
it shall determine.

     25.  Amendment.  This Agreement may be amended at any time  unilaterally by
the Company provided that such amendment is consistent with all applicable laws,
including  Section 409A of the Code,  and does not reduce any rights or benefits
you have accrued pursuant to this Agreement.  This Agreement may also be amended
in any manner consistent with all applicable laws, including Section 409A of the
Code, by a written consent executed by you and a duly authorized  representative
of the Company.

     26. The Plan.  This  Agreement  is  subject  to all the terms,  conditions,
limitations and  restrictions  contained in the Plan;  provided,  however,  that
notwithstanding anything to the contrary herein, any provision of this Agreement
that is  inconsistent  with the provisions of Section 9(c),  (e), and (f) of the
Plan shall control over such provisions of the Plan.


     27.  Agreement  Respecting  Securities Act of 1933. You represent and agree
that you will not sell the Common  Stock that may be issued to you  pursuant  to
your Performance  Units except pursuant to an effective  registration  statement
under the 1933 Act or pursuant to an exemption from registration  under the 1933
Act (including Rule 144).


     28. No Shareholder  Rights.  The Performance Units granted pursuant to this
Agreement  do not and shall not  entitle you to any rights as a  shareholder  of
Common Stock until



such time as you receive shares of Common Stock pursuant to this Agreement. Your
rights with respect to the  Performance  Units shall remain  forfeitable  at all
times prior to the date on which rights become  earned in  accordance  with this
Agreement.

     If you accept this  Performance Unit Award Agreement and agree to its terms
and conditions, please so confirm by signing and returning the duplicate of this
Agreement enclosed for that purpose.

                                               Very Truly Yours,
                                               PIONEER NATURAL RESOURCES COMPANY

                                               By:______________________________
                                               Name:____________________________
                                               Title:___________________________
                                               Date: ___________________________


ACKNOWLEDGED AND AGREED:

By:    _____________________________
Name:  _____________________________



                                                                      Appendix A

                    Determination of Performance Units Earned

Peer Companies:

  Apache Corporation                   Plains Exploration and Production Company
  Chesapeake Energy Corporation        Pogo Producing Company
  Cimarex Energy Co.                   Quicksilver Resources Inc.
  EOG Resources, Inc.                  Range Resources Corporation
  Newfield Exploration Company         XTO Energy Inc.
  Noble Energy, Inc.

In  addition,  if and  solely to the extent  that at the end of the  Performance
Period the number of companies  listed  above that qualify as Peer  Companies is
less  than  seven,  then  such  number  of the  following  additional  companies
(selected  in the order  presented  below) as is  necessary  to have  seven Peer
Companies  shall be treated as though Peer Companies for the entire  Performance
Period,  provided that each such additional company satisfies the requirement to
be a Peer  Company  throughout  the  Performance  Period.  If,  after adding all
eligible  alternative  companies,  the number of  companies  qualifying  as Peer
Companies for the Performance Period is less than seven, the Committee shall, in
good faith, determine the percentage of the Performance Units earned in a manner
consistent  with  the   requirements   to  qualify  the  Performance   Units  as
performance-based  compensation  exempt from the limitations  imposed by Section
162(m) of the Internal Revenue Code of 1986, as amended.

                                   Schedule I

     The  document  to  which  this  Schedule  I is  attached  is  the  form  of
Performance  Unit  Award  Agreement  between  the  Company  and each of Scott D.
Sheffield and Timothy L. Dove.

     The form of Performance  Unit Award  Agreement  between the Company and its
other executive officers varies from this Exhibit 10.2 by modifying Section 4(c)
to provide, in its entirety, the following:


     (c) Termination  Without Cause or Termination For Good Reason. In the event
that your employment with the Company and each of its  Subsidiaries by which you
are employed is terminated during the Performance  Period (x) by the Company and
such  Subsidiaries and such termination is not a Termination for Cause or (y) by
you and such  termination is a Termination for Good Reason (as each such term is
defined in the  Severance  Agreement  between  you and the Company or one of its
subsidiaries),  you  shall  be  deemed  to  have  earned,  as of the  end of the
Performance Period, that number of Performance Units equal to the product of (i)
the number of Earned  Performance Units that you would have earned in accordance
with  Section 2 had you  remained  employed  through the end of the  Performance
Period  multiplied  by  (ii)  the  Pro-Ration  Fraction.   Any  portion  of  the
Performance  Units that cannot become earned and payable in accordance  with the
preceding sentence shall terminate and automatically be cancelled as of the date
of your termination of employment. Any portion of your Performance Units that is
eligible to be earned  pursuant  to the second  preceding  sentence,  but is not
earned as of the end of the Performance Period,  shall terminate and be canceled
upon the expiration of such Performance Period.
