2.

Award .  Subject to the restrictions, limitations, terms and conditions specified in the Plan, Guidelines and this Agreement, effective as of the Award Date, Southwestern hereby grants the Participant ______ Performance Units.

3.

Performance Period . The Performance Units granted hereunder will become payable based on the satisfaction of the Performance Measures described in Section 6 below over the Performance Period, which, as determined by the Committee, shall be the period beginning ___________, 20__ and ending _____________, 20__.

4.

Unit Value . Each Performance Unit will have a “Target Value” of one share of Common Stock.  Based upon actual performance during the Performance Period against the Performance Measure(s) set forth in Section 6 below, the Payment Value of each Performance Unit may range from a minimum of 0 shares to a maximum of two shares as determined in Section 7 below. 

5.

Vesting .  Subject to Section 9 and Section 11 below, 100% of the Performance Units will vest on the ____ anniversary of the Award Date (“Vesting Date”), provided Participant is employed on the Vesting Date.

Performance Measures

Weight

Comparison

Performance Targets

Threshold

Target

Maximum









7.

Calculation of Payment Value . 

(a) The Committee shall certify in writing whether and to what the extent the Performance Target for each Performance Measure for the Performance Period has been met using, to the extent applicable, Southwestern’s year-end audited financial statements.

(b) The Committee will determine a “Payment Value” for each Performance Unit, expressed in shares of Common Stock, at the end of the Performance Period contingent upon the actual performance against the Performance Measure(s), as determined by the Committee.  Actual performance for all Performance Measure(s) (i) at Target would result in a Payment Value per Performance Unit of one share of Common Stock, (ii) at Threshold, one-half share of Common Stock and (iii) at Maximum, two shares of Common Stock.  For actual performance below Threshold, between Threshold and Target, and between Target and Maximum, the Payment Value will be determined by linear extrapolation, with a minimum of 0 and a maximum of two shares of Common Stock per Performance Unit.  Actual performance over maximum will not result in a Payment Value per Performance Unit greater than two shares of Common Stock.  [INSERT ANY ADDITIONAL LIMITATIONS OR METHODOLOGIES.]  The total payout to the Participant will be determined by multiplying the Payment Value per Performance Unit determined by the Committee based on the Company’s actual performance against, and weighting of, each Performance Measure by the number of vested Performance Units held by the Participant.

8.

Payout.     Subject to Section 11 below, Southwestern shall deliver to the Participant, at the election of the Committee in its sole discretion, either (a) a number of shares of Common Stock, less applicable tax withholdings (as set forth in Section 14), equal to the total payout under the Participant’s vested Performance Units determined by the Committee under Section 7(b) at the conclusion of the Performance Period on such date following the certification of performance against the Performance Measure(s) as the Committee shall designate, but in no event later than two and one-half months following the last day of the Performance Period, or (b) an amount in cash equal to the Fair Market Value as of the Vesting Date of the number of shares of Common

Stock that would have been issued under clause (a) had the Committee elected to deliver shares of Common Stock, and for the avoidance of doubt, may settle the Award using a combination of shares of Common Stock and cash in accordance with the foregoing.  No fractional shares will be issued.  If the calculation of the total payout under the Participant’s vested Performance Units results in a fractional share, it will be rounded up to the nearest whole share.

9.

(c) Termination Other than for Cause, Death, Disability or Retirement .  In the event that the employment of the Participant with the Company shall terminate for any reason other than Cause, Disability, Retirement or death, all unvested Performance Units granted to such Participant shall expire at the commencement of business on the date of such termination, and no payment shall be made to the Participant with respect thereto.  Except as otherwise provided herein or in the Plan or Guidelines, any vested Performance Units shall be paid out in accordance with Section 8 of this Agreement.

10.

Subsidiaries .  Unless the Committee determines otherwise, any unvested Performance Units held by a Participant employed by an entity that is a Subsidiary will terminate and be forfeited immediately on the date such entity ceases to be a Subsidiary of Southwestern.

11.

Change in Control .  Upon a Change in Control, all outstanding unvested Performance Units shall fully vest and each vested Performance Unit will be paid out at the greater of (i) Target Value and (ii) the projected Payment Value if the Performance Period had been completed, as determined by the Committee in its sole discretion. Any amounts payable under this Section 11 shall be paid in a lump sum within five business days following the Change in Control. 

12.

Limitations on Transfer .  No Performance Unit shall be assignable or transferable otherwise than by will or by the laws of descent and distribution.
