GRANT NOTICE FOR 2014 STOCK INCENTIVE PLAN

RESTRICTED STOCK UNIT AWARD

(Part B Awards)

The number of restricted stock units earned, if any, will be determined over up to three measurement periods referred to as the First Measurement Period, the Second Measurement Period and the Third Measurement Period (each a “Measurement Period” and together (i.e., from the start of the First Measurement Period to the end of the Third Measurement Period), the “Performance Period”), if applicable, based on the Company’s Stock Price Performance over each Measurement Period.  As described below, if the Payout Percentage for the First Measurement Period is 300% or less, payment under the award will be based solely on the First Measurement Period (the Second Measurement Period and Third Measurement Period will not apply).  If the Payout Performance for the First Measurement Period is greater than 300%, the Second Measurement Period and Third Measurement Period will apply.

The following table sets forth the number of restricted stock units, expressed as a percentage of the Target Dollar Value of RSUs, earned by the Participant based upon the Company’s Stock Price Performance over each Measurement Period (calculated in the manner set forth below):

* Payout Percentage for performance within the Stock Price Performance range shall be determined by linear interpolation.  For example, if Stock Price Performance was 25%, which falls 50% between 20% and 30%, the Payout Percentage would be similarly be 50% between 200% and 400% (i.e., 300%).  There is no payout under the Award if Stock Price Performance is 10% or below.

To determine the number of restricted stock units earned, if any, at the end of each Measurement Period, the following steps shall be taken:

First Measurement Period

At the end of the First Measurement Period, the Committee shall determine the Maximum RSU Award and the First Cap Amount, if applicable.

If the Maximum RSU Award is less than the First Cap Amount, the Maximum RSU Award will vest as of the last day of the Second Measurement Period, subject to Participant’s continuous employment through such time.  If the Maximum RSU Award is greater than the First Cap amount, the First RSU Vest Amount will vest as of the last day of the Second Measurement Period, subject to the Participant’s continuous employment through such time.

Second Measurement Period

If the Maximum RSU Award is greater than the First Cap Amount, the Committee shall determine the First Recalibrated RSU Award at the end of the Second Measurement Period.

If the First Recalibrated RSU Award is less than or equal to the First RSU Vest Amount, no additional restricted stock units under this Award shall vest at the end of the Second Measurement Period.  If the First Recalibrated RSU Award is greater than the First RSU Vest Amount, then the First RSU Vest Amount and the Second RSU Vest Amount shall vest as of the last day of the Second Measurement Period, subject to Participant’s continuous employment through such time.

Third Measurement Period

If the Maximum RSU Award is greater than the sum of the First RSU Vest Amount and the Second RSU Vest Amount, the Committee shall determine the Second Recalibrated RSU Award at the end of the Third Measurement Period.

If the Stock Price Performance at the end of the Third Measurement Period is equal to or higher than the Stock Price Performance at the end of the First Measurement Period, all of the Remaining Rollover Shares shall vest as of the last day of the Third Measurement Period.

If the Second Recalibrated RSU Award is less than or equal to the sum of the First RSU Vest Amount and the Second RSU Vest Amount, no additional restricted stock units under this Award shall vest. If the Second Recalibrated RSU Award is greater than the sum of the First RSU Vest Amount and the Second RSU Vest Amount, then the Third Vest Amount shall vest as of the last day of the Third Measurement Period.

The Third RSU Vest Amount shall be subject to the Participant’s continuous employment through the Second Measurement Period. Continuous employment through the Third Measurement Period is not required to earn the Third RSU Vest Amount.

Any restricted stock unit under this Award that is not earned at the end of the Third Measurement Period shall be forfeited.

Definitions

For purposes of this Award, the following terms shall mean:

“Actual Payout Percentage” shall equal the sum of the First RSU Vest, the Second RSU Vest and the Third RSU Vest, multiplied by the Ending Stock Price for the Third Measurement Period and divided by the Target Dollar Value of RSUs.

“Applicable Stock Price” shall mean the Ending Stock Price necessary to achieve the Stock Price Performance associated with a certain Payout Percentage.

“Beginning Stock Price” shall equal the average closing price of the Company’s common stock over the ten (10) trading day period ending on the trading day immediately preceding the first day of the First Measurement Period; provided, however, if the Award is granted after September 30, 2019, the Beginning Stock Price will be adjusted to equal the Effective Stock Price if the Beginning Stock Price is greater than the Effective Stock Price. Notwithstanding the foregoing, in the event the Maximum RSU Award for the Prior Award is less than the First Cap Amount for the Prior Award, the Beginning Stock Price will not be adjusted.

“Effective Stock Price” shall mean the Applicable Stock Price of the Prior Award, determined based on the Actual Payout Percentage of the Prior Award.

“Ending Stock Price” shall equal the average closing price of the Company’s common stock over the ten (10) trading day period ending on the last trading day of the applicable Measurement Period.

“First Cap Amount” shall mean the number of restricted stock units that would vest for the First Measurement Period based on a Payout Percentage of 300%.  The First Cap Amount is calculated as follows: Target Dollar Value of RSUs multiplied by 300% divided by the Applicable Stock Price at 300% as of the end of the First Measurement Period.

“First Measurement Period” shall mean the period that begins on the first day of the Performance Period and ends on the last day of the fourth quarter following such date.

“First Recalibrated RSU Award” shall mean the number of restricted stock units that would have been awarded for the First Measurement Period had the Stock Price Performance been calculated at the end of the Second Measurement Period (rather than the First Measurement Period). First Recalibrated RSU Award is calculated as follows: Target Dollar Value of RSUs multiplied by the Payout Percentage based on the Stock Price Performance through the Second Measurement Period divided by the Ending Stock Price of the Second Measurement Period.

“First RSU Vest Amount” shall mean a number of restricted stock units equal to the lower of the Maximum RSU Award and the First Cap Amount.

“Grant Price” shall equal the Beginning Stock Price multiplied by 1.15.

“Initial Rollover Shares” shall mean the difference between the Maximum RSU Award and the First RSU Vest Amount.

“Maximum RSU Award” shall mean the number of restricted stock units that would vest based on performance solely through the end of the First Measurement Period. The Maximum RSU Award is calculated as follows: Target Dollar Value of RSUs multiplied by the Payout Percentage based on the Stock Price Performance through the First Measurement Period divided by the Ending Stock Price of the First Measurement Period.

“Prior Award” shall mean the award of restricted stock units, the First Measurement Period of which ended immediately before the Grant Date.

“Remaining Rollover Shares” shall mean the difference between the Maximum RSU Award and the sum of the First RSU Vest Amount and the Second RSU Vest Amount.

“Second Measurement Period” shall mean the period that begins on the first day of the Performance Period and ends on the last day of the fifth quarter following such date.

“Second Recalibrated RSU Award” shall mean the number of restricted stock units that would have been awarded for the First Measurement Period had the Stock Price Performance been calculated at the end of the Third Measurement Period (rather than the First Measurement Period). Second Recalibrated RSU Award is calculated as follows: Target Dollar Value of RSUs multiplied by the Payout Percentage based on the Stock Price Performance through the Third Measurement Period divided by the Ending Stock Price of the Third Measurement Period.

“Second RSU Vest Amount” shall mean lower of (a) the difference between the First Recalibrated RSU Award and the First RSU Vest Amount, (b) the Initial Rollover Shares, and (c) the First Cap Amount.

“Stock Price Performance” shall be calculated as the percentage increase from the Company’s Beginning Stock Price to the Ending Stock Price, adjusted for dividends paid during the applicable Measurement Period (assuming such dividends are reinvested in the Company’s common stock on the dividend payment date).

“Target Dollar Value of RSUs” shall equal the Target Number of RSUs multiplied by the Grant Price.

“Target Number of RSUs” shall be the target number of restricted stock units set forth on the Grant Notice.

“Third Measurement Period” shall mean the period that begins on the first day of the Performance Period and ends on the last day of the sixth quarter following such date.

“Third RSU Vest Amount” shall mean the lower of (a) the difference between the Second Recalibrated RSU Award and the sum of the First RSU Vest Amount and the Second RSU Vest Amount, and (b) the Remaining Rollover Shares.
