OUTPERFORMANCE AWARDS

2.1. Awards.

2.1.1. Award Grant. The Committee may grant Awards from time to time. Each Award shall entitle the Participant to whom the Award is granted to that number of Common Shares (if any), calculated as of the Measurement Period Ending Date, equal to the quotient that results by dividing the Participant’s Award Value (if any) by the Common Share Price on the Measurement Period Ending Date (with fractional Common Shares rounded up to the nearest whole number). Payments on account of each Award will be made in Common Shares (“Award Shares”) and will be made as soon as reasonably practicable following the Measurement Period Ending Date and the Award Shares will be subject to vesting as provided in Section 2.2.1 below; provided that if as of the Measurement Period Ending Date an insufficient number of Common Shares remains available for issuance under the Plan to provide for payment in full of Awards, then the amount of Award Shares issued to each Participant shall be reduced, pro rata based on each Participant’s entitlement to Award Shares, and no payments will be made on account of the remaining portion of the Award Value; provided that the Committee may, in its sole discretion, authorize the issuance of Common Shares in lieu of such pro rata reduction under another employee benefit plan maintained by the Company that permits such issuance if such issuance complies with law and rules of the New York Stock Exchange.

2.1.2. Dividend Equivalent Payments. At the time that the Company makes a payment on account of each Award to a Participant, the Company shall also make an additional payment (a “Dividend Equivalent Payment”) to the Participant in an amount equal to the product obtained by multiplying the Dividend Value by the number of Award Shares issuable to the Participant in payment of the Award. Payments on account of the Dividend Equivalent Payment will be made in Common Shares, and the number of Common Shares, if any, issued in satisfaction of such Dividend Equivalent Payment shall equal the quotient that results from dividing the amount of the Dividend Equivalent Payment by the Common Share Price on the Measurement Period Ending Date (with fractional Common Shares rounded up to the nearest whole number). Common Shares issued in payment of all or a part of the Dividend Equivalent Payment shall not be subject to vesting or risk of forfeiture. If as of the time the Company is to make Dividend Equivalent Payments an insufficient number of Common Shares remains available for issuance under the Plan to provide for payment in full of the Dividend Equivalent Payments, then the amount of Common Shares issued to each Participant on account of Dividend Equivalent Payments shall be reduced, pro rata based on each Participant’s entitlement to Dividend Equivalent Payments, and no payments will be made on account of the remaining portion of the Dividend Equivalent Payments; provided that the Committee may, in its sole discretion, authorize the issuance of Common Shares in lieu of such pro rata reduction under another employee benefit plan maintained by the Company that permits such issuance if such issuance complies with law and rules of the New York Stock Exchange. No Dividend Equivalent Payment will made if a pro rata reduction of Award Shares has been made under Section 2.1.1.

2.2.2. Termination of Employment. If, prior to the applicable vesting date specified in Section 2.2.1, a Participant’s employment with the Company or a Subsidiary terminates for any reason other than the Participant’s death or Disability, then the unvested portion of the Participant’s Award shall be immediately cancelled and no Award Shares shall be distributed in respect thereof and any unvested Award Shares previously issued shall be forfeited and cancelled; provided, however, that in the case of the Company’s President and Chief Executive Officer, if his employment terminates due to (a) a termination without Cause (as defined in his Employment Agreement) by the Company or a Subsidiary or (b) his Resignation for Good Reason (as defined in his Employment Agreement), then he shall be treated for all purposes of this Program as if he had remained employed by the Company through each applicable vesting date.

2.2.5. Interim Vesting Date. Notwithstanding any other provision herein but subject to the terms and conditions of the applicable Award Agreement, in the event of an Interim Vesting Date, then each Participant shall be entitled to receive that number of Common Shares equal to the quotient that results by dividing (a) the product obtained by multiplying the Participant’s Award Percentage by $27,500,000 by (b) the Common Share Price on the Interim Vesting Date (with fractional Common Shares rounded up to the nearest whole number); and from and after the Interim Vesting Date, the reference in the definition of Outperformance Amount I to “$13,750,000” shall be changed to “$6,875, 000” and the reference in the definition of Outperformance Amount II to “$41,250,000” shall be changed to “$20,625, 000”; provided, however, that the Common Shares to which each Participant shall become entitled on an Interim Vesting Date shall not be issued to the Participant until the arrival of the Measurement Period Ending Date and the issuance of such Common Shares on the Measurement Period Ending Date shall be subject to the same vesting schedule and risk of forfeiture applicable to Common Shares provided for in Section 2.2.

2.3. Payments by Participants. No amount shall be payable to the Company by any Participant in respect of an Award.

2.4. Dividends.

Upon cancellation of any Award Shares, future payment of dividends or distributions with respect to such cancelled Award Shares will cease immediately.

Following deferral pursuant to this Section 2.5, the Award Shares and Common Shares issued in payment of Dividend Equivalent Payments subject to the deferral election shall be governed by the terms of the Deferred Compensation Plan (and amounts deferred into the Deferred Compensation Plan shall be in Common Share rather than in Common Share equivalents). The Company may eliminate this Section 2.5 or modify, amend or terminate a Participant’s deferral election pursuant to the Deferred Compensation Plan at any time, in its sole discretion, and in any event a Participant’s entitlement to make a deferral election under this Section 2.5 shall be conditioned on inclusion in the Deferred Compensation Plan of provisions for the holding of Common Shares thereunder and agreement by the Participant not to transfer the Common Shares into another

ment alternative thereunder and such additional conditions as the Committee may determine.
