Earning of Performance RSUs. Until the applicable vesting date(s) provided below, # the Performance RSUs shall be subject to forfeiture by the Participant to the Company as provided in this Agreement, and # the Participant may not sell, assign, transfer, discount, exchange, pledge or otherwise encumber or dispose of any of the Performance RSUs unless the restrictions have terminated in accordance with the provisions of this Agreement.

Adjustment of Performance Objectives. The Committee may modify, amend or otherwise adjust the performance objectives specified for outstanding Performance Share Awards if it determines that an adjustment would be consistent with the objectives of this Plan and taking into account the interests of the participants and the public Shareholders of the Company and such adjustment complies with any applicable legal requirements. The types of events which could cause an adjustment in the performance objectives include, without limitation, accounting changes which substantially affect the determination of performance objectives, changes in applicable laws or regulations which affect the performance objectives, and divisive corporate reorganizations, including spin-offs and other distributions

Performance Goals and Adjustment. Adjusted PSUs shall be the number of PSUs that become eligible for the lapse of restrictions, pursuant to paragraph 3, contingent on achievement of the following goals for the March 19, 2019 to December 31, 2021 performance period:

RSUs. The restrictions on any RSUs (other than your September 3, 2020 Special RSU Award) will lapse (i.e, those RSUs will be vested) in accordance with the terms of the respective awards.

On the terms and conditions and subject to the restrictions, including forfeiture, hereinafter set forth, the Company hereby grants to the Participant a target number of Performance RSUs equal to ​ (the “Target RSU Award”). The actual number of Performance RSUs which the Participant will earn under this Agreement will be finally determined based upon the Company’s Relative Total Shareholder Return and Free Cash Flow achievements for the period commencing on January 1, 2015 and ending on December 31, 2017 (the “Performance Period”), in accordance with the provisions of [Exhibit A] attached to this Agreement and made a part hereof.

Performance RSUs Subject to Plan. By entering into this Agreement, the Participant agrees and acknowledges that the Participant has received and read a copy of the Plan. All Performance RSUs are subject to the Plan. In the event of a conflict between any term or provision contained herein and a term or provision of the Plan, the applicable terms and provisions of the Plan will govern and prevail.

Committee’s Adjustment of Performance Percentage. Notwithstanding any provision hereof or in the Plan to the contrary, the Committee, in its sole discretion, by Committee resolution passed prior to the Vesting Date, may adjust Holder’s otherwise earned Performance Percentage in an amount (if any) determined by the Committee based upon its subjective evaluation; provided, that, any adjustment of Holder’s Performance Percentage by the Committee for the Performance Period shall be determined after the end of the Performance Period, and shall not exceed twenty-five percent (25%) of Holder’s Performance Percentage otherwise earned during the Performance Period.

Adjustment of Performance-Based Compensation. Awards that are designated as Performance-Based Compensation may be adjusted upward or downward, either on a formula or discretionary basis or any combination, as the Compensation Committee determines.

Adjustment. In the event of a stock split, a stock dividend or a similar change in Company stock, the number of Shares covered by the Option and the Exercise Price per Share may be adjusted pursuant to the Plan.

Adjustment. The individual goals performance component of each Participant’s Annual Incentive Award (determined without application of this Section 4.4) is subject to the aggregate funded amount for the individual goals performance component of all Participants (determined based on the AOI Performance Factor) and to adjustment by managers. Such adjustment may be negative for those Participants who do not achieve the applicable goals, and positive for those Participants who demonstrate outstanding accomplishments. For purposes of applying this Section 4.4, any positive adjustment made to the individual goals performance component of the Annual Incentive Award of one Participant must result in a dollar-for-dollar negative adjustment to the individual goals performance component of the Annual Incentive Award of one or more other Participants so that, in the aggregate, the application of the manager adjustment described in this Section 4.4 to all the Participants shall not result in any additional cost to the Company and its Affiliates for the group of Participants over which a particular manager retains authority.

Adjustment. In the event of any equity restructuring, whether a stock dividend, recapitalization, split-up or combination of shares, or otherwise, affects the Common Stock such that an adjustment is required in order to preserve the benefits intended to be provided by the Plan, the Committee (subject in the case of Incentive Stock Options to any limitation required under the Code) shall equitably adjust any or all of # the number and kind of shares in respect of which Awards may be made under the Plan, # the number and kind of shares subject to outstanding Awards and # the exercise price with respect to any of the foregoing, provided that the number of shares subject to any Award shall always be a whole number.

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.

Adjustment Provisions. If, through or as a result of any merger, consolidation, sale of all or substantially all of the assets of the Company, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar transaction, # the outstanding shares of Common Stock are increased, decreased or exchanged for a different number or kind of shares or other securities of the Company, or # additional shares, or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Common Stock or other securities, an appropriate and proportionate adjustment shall be made in # the maximum number and kind of shares reserved for issuance under the Plan, # the number and kind of shares or other securities subject to any then outstanding Options, and # the price for each share or other security subject to any then outstanding Options, so that upon exercise of such Options, in lieu of the shares of Common Stock for which such Options were then exercisable, the relevant optionee shall be entitled to receive, for the same aggregate consideration, the same total number and kind of shares or other securities, cash or property that the owner of an equal number of outstanding shares of Common Stock immediately prior to the event requiring adjustment would own as a result of the event. If any such event shall occur, appropriate adjustment shall also be made in the application of the provisions of this Section 14 and Section 15 with respect to Options and the rights of optionees after the event so that the provisions of such Sections shall be applicable after the event and be as nearly equivalent as practicable in operation after the event as they were before the event.

Adjustment Provisions. In order to prevent dilution of and to the conversion rights of the Holder hereunder, the number of shares of Common Stock to be issued by the Borrower upon conversion hereof shall be subject to adjustment from time to time as provided in this [Section 7]. For purposes of this [Section 7], the term “Common Stock” shall mean the Common Stock and any other class of stock ranking on parity with such stock.

Investment Adjustment. The investment income, gains and losses shall be determined for the Accounts in accordance with the following:

Adjustment Event. If an Adjustment Event occurs, the parties must do all things necessary to make sure that the Adjustment Event may be properly accounted for, including the issue of an Adjustment Note.

Investment Adjustment. For each Plan Year quarter or other period, the Participant’s Deferred Compensation Account shall be increased or decreased as if it had earned the rate of return corresponding to the amount determined by the Committee under Paragraph 7.4. Such increase or decrease shall be based on the balance in the Deferred Compensation Account throughout the Plan Year quarter or other period and shall be credited at such time as the Committee in its sole discretion shall determine.

Performance RSUs Payable in Shares. Notwithstanding any discretion in the Plan or anything to the contrary in the Award, Performance RSUs granted to the Participant in the United Kingdom do not provide any right for the Participant to receive a cash payment; the Performance RSUs are payable only in Shares.
