All capitalized terms used herein shall have the meaning specified in the Plan, unless another meaning is specified herein.

In accordance with this grant, and as a condition thereto, the Company agrees as follows:

SECTION 2.Nature of Award. The Target Award represents the opportunity to receive a future payment equal to a number of shares of Company common stock, par value $0.01 per share (the “Performance Shares”), to be delivered in the form of unrestricted common stock, as are earned in accordance with Section 3 and Section 4 of this Award Agreement.

SECTION 3.Determination of Number of Shares Earned. The number of Performance Shares earned as of the end of the Performance Period, if any, shall be determined as follows (subject to the Participant’s continued employment through December 26, 2015, except as provided under Section 5):

For purposes of this Award Agreement:

“# Target Award” means the number of Performance Share Units comprising the Target Award in Section 1, above.

“EPS Payout Percentage” means the percentage multiplier as determined in the table below:

As shown in the table above, if [YEAR] Non-GAAP EPS falls at or between 90% and 110% of the [YEAR] Non-GAAP EPS Target, EPS Payout Percentage will be calculated based upon a linear interpolation using the table above.

“[YEAR] Non-GAAP EPS” means the Company’s reported [YEAR] Non-GAAP earnings per share as reported in its earnings releases.

“[YEAR] Non-GAAP EPS Target” means $ [TO FILL IN AT TIME OF GRANT].

“TSR” means Total Shareholder Return, which is the share price appreciation of any particular company’s publicly traded common stock plus dividends accrued, as measured during the Performance Period. The starting and ending points for calculating a company’s 3-year TSR are the average closing stock price of the common stock for the twenty (20) trading days prior to the start or end date of the Performance Period, as applicable. For purposes of clarity, any dividends will be accrued as cash, summing all dividends over the Performance Period.

“TSR Payout Percentage” means the percentage multiplier as determined in the table below:

As shown in the table above, between each of the 5 percentile levels, the TSR Payout Percentage will be calculated based upon a linear interpolation. For example, there is linear interpolation between the 10th^th Percentile and the 25^th Percentile, and a separate linear interpolation between the 25^th Percentile and the 50^th Percentile.

“Relative 3-year TSR Percentile” means the comparative percentile of the Company’s 3-year TSR as compared to the TSRs for the companies in the Peer Group.

“Peer Group” means the companies within the S&P 1500 Healthcare Index with the same 2-digit GICS code as the Company; provided, however, that the Peer Group shall include only companies found within the S&P 1500 Healthcare Index at both (1) the start and (2) the end of the Performance Period. By way of clarity, but not intended to address all circumstances:

In addition, the Compensation Committee shall have the authority to make other appropriate adjustments in response to a change in circumstances that results in a member of the Peer Group no longer satisfying the criteria for which such member was originally selected.

The total “# of Shares” earned shall be determined by the Compensation Committee of the Board of Directors of the Company (the “Administrator”) in its sole discretion based on the formula set out above in this Section 3. The Payout Percentage may be as low as 0%, or as high as 200%. The Administrator shall make the determination of the EPS Payout Percentage at a meeting of the Administrator to occur in the first calendar quarter of fiscal 2014, and shall make the determination of the # of Shares at a meeting of the Administrator to occur in the first calendar quarter of fiscal year 2016; provided, however, that the Administrator has the discretion to make such determination and/or grant of # of Shares at such time or times as it deems acceptable in the sole discretion of the Administrator.

TRS Outperformance Override Feature. Notwithstanding the foregoing, in the event that (a) [YEAR] Non-GAAP EPS as a % of [YEAR] Non-GAAP EPS Target is less than 90% but greater than 85% and (b) the Relative 3-year TSR Percentile is 75^th percentile or greater, then the # of Shares earned as of the end of the Performance Period, if any, shall be determined as follows:

For purposes of this Award Agreement:

“TRS Outperformance Payout Percentage” “means the percentage multiplier as determined in the table below:

As shown in the table above, between 85% of [YEAR] Non-GAAP EPS Target and 89.99% Non-GAAP EPS Target, TRS Outperformance Payout Percentage will be calculated based upon a linear interpolation.

SECTION 4.Payment of Performance Shares. The Performance Shares payable to a Participant as determined by the Payout Percentage calculated pursuant to Section 3 shall be as follows:
