Adjustment. Pursuant to Section 9 of the Plan and the Guidelines, the Committee will (in the case of a Covered Employee) and may (with respect to other Participants) adjust the Performance Targets for the relevant Performance Period to exclude the impact of charges for restructurings, discontinued operations, extraordinary items, all non-cash charges resulting from any write-down of oil and gas properties and all other non-cash components of Accumulated Other Comprehensive Income (AOCI), other unusual or non-recurring items, and the cumulative effect of accounting changes, each as defined by generally accepted accounting principles and as identified in Southwestern’s audited financial statements, including the notes thereto.

In the event of any other change in corporate capitalization, including a merger, consolidation, reorganization, or partial or complete liquidation of the Company, such equitable adjustments described in the foregoing sentence may be made as determined to be appropriate and equitable by the Committee (or, if the Company is not the surviving corporation in any such transaction, the board of directors of the surviving corporation) to prevent dilution or enlargement of rights of participants. The decision of the Committee regarding any such adjustment and the Fair Market Value of any fractional security shall be final, binding and conclusive.

Adjustment of Number of Shares. Upon each adjustment in the Exercise Price pursuant to [Section 5(c)] above, the number of Shares of Applicable Stock purchasable hereunder shall be adjusted, to the nearest whole share, to the product obtained by multiplying the number of Shares purchasable immediately prior to such adjustment in the Exercise Price by a fraction, the numerator of which shall be the Exercise Price immediately prior to such adjustment and the denominator of which shall be the Exercise Price immediately thereafter.

Notwithstanding the foregoing, no such adjustment shall be authorized to the extent that such adjustment would cause the Option to violate Section 424(a) of the Internal Revenue Code of 1986, as amended from time to time (the “Code”) or otherwise subject (in the determination of the Committee) any Grantee to taxation under Section 409A of the Code; and provided further that the number of Shares subject to the Option shall always be a whole number.
