VESTING OF SHARES

Section 2.1 – General

For purposes of vesting, the Performance Shares shall be divided into two categories, each consisting of fifty percent (50%) of the Performance Shares (“Vesting Category 1” and “Vesting Category 2”).

Section 2.2 – Conditions of Vesting

Except as may be otherwise provided in Section 2.2 of this Agreement, the vesting of your rights and interest in the Performance Shares, and the effect of termination of your employment or service with the Company, cessation of service as a Senior Leader or attainment of age 64 prior to the date on which the Performance Shares become fully vested and nonforfeitable or are forfeited, shall be determined in accordance with this Section 2.2.

(a) EPS Condition. It shall be a condition to the vesting of the Performance Shares in Vesting Category 1 and Vesting Category 2 that the Compound Annual Growth Rate (“CAGR”) of the Company’s earnings per share (as defined below) during the five-year period beginning on January 1, 2011, and ending on December 31, 2015 (“EPS Performance Period”) equal at least seven and one-half percent (7.5%) (the “EPS Condition”). The CAGR of the Company’s earnings per share for the EPS Performance Period shall be determined by comparison of the earnings per share for the Company’s fiscal year ending December 31, 2010, that is, $1.12 per share, to the sum of the earnings per share for the Company’s fiscal years ending December 31, 2011, 2012, 2013, 2014 and 2015, which must equal or exceed $6.99 per share in order for the EPS Condition to be satisfied, as illustrated by the schedule (the “Senior Leader EPS Condition Schedule”) attached hereto. For purposes of this Agreement, the Company’s earnings per share shall be calculated in accordance with generally accepted accounting principles recognized in the United States of America (“GAAP”), except that such calculation shall be (i) without regard to the impact of the line item in the Company’s income statement filed as part of the Company’s Annual Report on Form 10-K relating to earn-out payments associated with acquisitions captioned “Change in estimated acquisition earnout payables,” required by Accounting Standards Codification Topic 805 - Business Combinations, or any comparable or equivalent amount reported in future filings pursuant to future accounting rule requirements, and (ii) subject to adjustment for such items (for example, extraordinary, nonrecurring items) as, in the sole and absolute discretion of the Committee, are determined to be appropriately disregarded for all grantees whose agreements include an EPS Condition. Any such adjustment made by the Committee shall be final and binding upon the Grantee, the Company, their respective heirs, administrators, personal representatives, successors, assigns, and all other interested persons. If the EPS Condition is satisfied, one hundred percent (100%) of the Performance Shares shall be awarded upon written certification by the Committee of the satisfaction of the EPS Condition, subject to the provisions of Section 2.2(c) (“Employment Conditions”), below. If the EPS Condition is not satisfied, then one hundred percent (100%) of the Performance Shares shall be forfeited.

(b) Additional Shares in the Event of Superior Earnings Per Share. If the CAGR of the Company’s earnings per share, determined in accordance with section 2.2(a), above, for the EPS Performance Period exceeds ten percent (10%) (the “Additional EPS Condition”), the Additional Shares identified in Section 1.1 of this Agreement shall be awarded upon written

certification by the Committee of the earnings per share performance results, subject to the requirements of Section 2.2(c) (“Employment Conditions”), below. In order for this increase to occur, the sum of the earnings per share for the Company’s fiscal years ending December 31, 2011, 2012, 2013, 2014, and 2015 must equal or exceed $7.52. The additional shares attributable to such increase (the “Additional Shares”) shall be included in Vesting Category 2.

(c) Employment Conditions. In the event that you cease to serve as a Senior Leader of the Company for any reason prior to the end of the EPS Performance Period, your interest in the Vesting Category 1 Performance Shares will be forfeited. In the event that you continue to serve as a Senior Leader of the Company at the end of the EPS Performance Period, your interest in any Performance Shares that are awarded in accordance with Section 2.2(a) (the “Awarded Performance Shares”) or (b) (the “Awarded Additional Shares”) of this Agreement will become fully vested and nonforfeitable in accordance with the following:

(i) Awarded Performance Shares in Vesting Category 1. With respect to the Awarded Performance Shares in Vesting Category 1, your interest will become vested and nonforfeitable in three (3) equal installments, on January 1 of 2017, 2018 and 2019, respectively, provided that the EPS Condition and any other conditions described in this Section 2.2 have been satisfied and provided, in each instance, that you have been continuously employed by the Company from the effective date of this Agreement until December 31 of the calendar year ending immediately prior to each such date.

If your employment terminates for any reason before one of the vesting dates specified in this Section 2.2(c)(i), your interest in the unvested Awarded Performance Shares in Vesting Category 1 will be forfeited unless (1) your employment with the Company terminates as a result of your death or disability, as defined in the Plan, (2) you have attained the age of 64, or (3) the Committee, in its sole and absolute discretion, waives the conditions of the grant of the Vesting Category 1 Performance Shares.

In the event that you attain age 64 before one of the vesting dates specified in this Section 2.2(c)(i), and the EPS Condition is satisfied, the unvested Awarded Performance Shares in Vesting Category 1 will vest in the later of (A) 2016 (the year in which the EPS Condition is satisfied) or (B) the year in which you attain age 64, in such proportion as the number of years since January 1, 2011 bears to the number “8,” and will continue to vest in the proportion of 1/8 each year thereafter until the eighth year is reached, so long as you continue to be employed by the Company. For example, if you attain age 64 six years after January 1, 2011, and the EPS Condition has been satisfied, 6/8 of the unvested Awarded Performance Shares in Vesting Category 1 will vest in the year in which you attain age 64, and thereafter, 1/8 of such Awarded Performance Shares will vest each year for the next two years, so long as you continue to be employed by the Company. As a second example, if you are age 66 as of January 1, 2016, and the EPS Condition is satisfied, 5/8 of the Awarded Performance Shares in Vesting Category 1 will vest in 2016 upon the anniversary date of this Agreement following the award of the Vesting Category 1 Performance Shares, and thereafter, 1/8 of such Awarded Performance Shares will vest on January 1 of each year for the next three years, so long as you continue to be employed by the Company.

In the event that your employment with the Company terminates as a result of your death or disability after the EPS Condition has been satisfied (the “EPS Condition Satisfaction Date”), but before your interest in the Performance Shares in Vesting Category 1 becomes fully vested and nonforfeitable or is forfeited, the unvested Vesting Category 1 Awarded Performance Shares will vest in the year in which such termination of your employment with the Company occurs in such proportion as the number of years since January 1, 2011 bears to the number eight (8).

(ii) Awarded Performance Shares in Vesting Category 2 and Awarded Additional Shares. With respect to the Awarded Performance Shares in Vesting Category 2 and the Awarded Additional Shares, if any, your interest will become vested and nonforfeitable on January 1, 2021, provided that you have been continuously employed by the Company since the effective date of this Agreement, and provided that the EPS Condition and any other conditions described in Section 2.2(a) and, if applicable, Section 2.2(b) of this Agreement have been satisfied. If your employment terminates for any reason before December 31, 2020, your interest in the Vesting Category 2 Awarded Performance Shares and the Awarded Additional Shares will be forfeited unless (1) you have attained the age of 64, (2) your employment with the Company terminates as a result of your death or disability, as defined in the Plan, or (3) the Committee, in its sole and absolute discretion, waives the conditions of the grant of the Vesting Category 2 Awarded Performance Shares and the Awarded Additional Shares.

In the event that you attain age 64 before January 1, 2021, and the EPS Condition and, if applicable, the Additional EPS Condition are satisfied, the Awarded Performance Shares in Vesting Category 2 and the Awarded Additional Shares will vest, in the later of (A) 2016 (the year in which the EPS Condition and Additional EPS Condition are satisfied) or (B) the year in which you attain age 64, in such proportion as the number of years since January 1, 2011 bears to the number “10,” and will continue to vest in the proportion of 1/10 each year thereafter until the tenth year is reached, so long as you continue to be employed by the Company. For example, if you attain age 64 eight years after January 1, 2011, and the EPS Condition has been satisfied, 8/10 of the Awarded Performance Shares in Vesting Category 2 and the Awarded Additional Shares will vest in the year in which you attain age 64, and thereafter, 1/10 of such Awarded Performance Shares will vest each year for the next two years, so long as you continue to be employed by the Company. As a second example, if you are age 66 as of January 1, 2016, and the EPS Condition is satisfied, 5/10 of the Awarded Performance Shares in Vesting Category 2 and the Awarded Additional Shares will vest in 2016 upon the award of the Vesting Category 2 Performance Shares and the Additional Shares, and thereafter, 1/10 of such Awarded Performance Shares will vest on the anniversary of the effective date of this Agreement each year for the next five years, so long as you continue to be employed by the Company.

In the event that your employment with the Company terminates as a result of your death or disability after the EPS Condition Satisfaction Date, but before your interest in the Awarded Performance Shares in Vesting Category 2 and, if applicable, the Awarded Additional Shares, becomes fully vested and nonforfeitable or is forfeited, the Awarded Performance Shares in Vesting Category 2 and the Awarded Additional Shares will vest in the year in which you die

or become disabled in such proportion as the number of years since January 1, 2011 bears to the number “10.”

(d) Issuance of Stock Certificates. A certificate representing the vested Performance Shares and Additional Shares will be transferred to you as soon as practicable after satisfaction of all applicable conditions set forth in Sections 2.2(a), (b), and (c) of this Agreement, subject to the provisions of Section 3.3 (“Withholding”).

(e) Dividend Rights. If a cash dividend is declared on shares of the Company’s common stock after the EPS Condition Satisfaction Date, but before your interest in the Performance Shares and, if applicable, the Additional Shares becomes fully vested and nonforfeitable or is forfeited, the Company will pay the cash dividend directly to you with respect to the Awarded Performance Shares and the Awarded Additional Shares. If a stock dividend is declared after the EPS Condition Satisfaction Date, but before your interest in the Awarded Performance Shares and the Awarded Additional Shares becomes fully vested and nonforfeitable or is forfeited, the stock dividend will be treated as part of the grant of that portion of the related Awarded Performance Shares and Awarded Additional Shares, and your interest in such stock dividend will become nonforfeitable or be forfeited at the same time as the Awarded Performance Shares and the Awarded Additional Shares with respect to which the stock dividend was paid become nonforfeitable or is forfeited. The disposition of each other form of dividend that may be declared after the EPS Condition Satisfaction Date, but before your interest in the Awarded Performance Shares and Awarded Additional Shares becomes fully vested and nonforfeitable or is forfeited will be made in accordance with such rules as the Committee may adopt with respect to such dividend.

(f) Voting Rights. You will be allowed to exercise voting rights with respect to Awarded Performance Shares and Awarded Additional Shares even though your interest in such Awarded Performance Shares and Awarded Additional Shares has not yet become fully vested and nonforfeitable.

Section 2.3 – Termination After Transfer of Control
