the Performance Share Plan);

WHEREAS, pursuant to duly adopted resolutions, the Board of Directors of the Company has
elected to adopt an amendment (the Amendment) to the Performance Share Plan as further described herein;

WHEREAS, the
Board of Directors of the Company is permitted to amend the Performance Share Plan under certain circumstances without stockholder approval pursuant to Section 19 therein; and

Plan.

2. Section 2(b) of the Performance Share Plan is hereby deleted in its entirety and replaced with the following revised
Section 2(b):

Award Period means the period of calendar years (but no more than ten years) fixed by the
Committee with respect to all classes of Awards with the same Date of Grant, commencing with each Date of Grant, except that (i) the Award Period for an Employee whose normal retirement date (as determined under the Companys corporate

3. Section 5(c) of the Performance Share Plan is hereby deleted in its entirety and replaced with
the following revised Section 5(c):

Payment of the Award to any Participant shall be made in accordance with
Section 6 and shall be subject to such conditions for payment as the Committee may prescribe at the time the Award is made. The Committee may prescribe different conditions for different Participants. Such conditions may be expressed in terms
of: (i) the growth in Net Income Per Share during the Award Period, or (ii) Return on Average Equity in comparison with other banks and bank holding companies during the Award Period, or (iii) the growth in Stockholders Equity
Per Share or tangible Stockholders Equity Per Share, or (iv) other reasonable bases; provided that, to the extent the Committee determines that it is necessary to qualify compensation under Section 162(m), the performance criteria
shall be based on one or more of the criteria listed in (i), (ii) or (iii) above. Any provision of the Plan to the contrary notwithstanding, Performance Shares that are intended to qualify as performance-based compensation under
Section 162(m) shall be granted and administered in accordance with the applicable requirements of Section 162(m) and be subject to such other terms and conditions as the Committee may impose. Subject to the terms of the Plan, each of the
measures described in (i), (ii) or (iii) above may include or exclude discontinued operations, unusual items, non-recurring items, and extraordinary items, as determined by the Companys auditors, and the effects of changes in
accounting standards. In addition, in the event that the Committee determines that it is advisable to grant Awards which shall not qualify for the performance-based exception under Section 162(m), the Committee may make such grants without
satisfying the requirements of Section 162(m).

4. Except as hereby amended, the Performance Share Plan remains in full force and
effect, as written.
