Incentive Plan, as amended (the “Plan”), which shall be payable if certain
performance and other conditions are satisfied as described below.

1. Grant of Performance Award.

You have been granted an award (the “Award) consisting of a total of          
units (“Units”). To be entitled to any payment under the Award, you must execute
this Agreement and return a fully executed copy to the Company, and all terms
and conditions of this Award must have been satisfied. The Award will be
payable, if at all, based in part on the achievement by the Company of certain
performance measures (described below and in Exhibit I) over the two-year period
commencing January 1, 2006 and ending on December 31, 2007 (the “Performance
Period”). The date on which the Performance Period ends (December 31, 2007) is
referred to herein as the “Maturity Date.”

2. Performance Targets: Committee Certification.

Whether your Award will be paid and if so in what amounts will depend in part
(i) as to seventy (70%) percent of the Award (the “EPS Portion”), on the
Company’s achievement of specified earnings per share targets as described in
(a) below and in Exhibit I, and (ii) as to the remaining thirty (30%) percent of
the Award (the “ROE Portion”), on the Company’s achievement of specified return
on shareholders’ equity targets as described in (b) below and in Exhibit I.

(a) Earnings Per Share (EPS). Subject to the other terms and conditions of the
Award, the Company’s full diluted aggregated earnings per share from continuing

operations (“EPS”) for the Performance Period will determine how much, if any,
of the EPS Portion of the Award will be payable. Exhibit I sets forth the EPS
threshold that must be achieved if any of the EPS Portion is to be payable and
the higher EPS target that must be achieved if the entire EPS Portion is to be
payable, with interpolation for EPS performance between those limits.

(b) Return on Equity (ROE). Subject to the other terms and conditions of the
Award, the Company’s average return on shareholders’ equity from continuing
operations (“ROE”) will determine how much, if any, of the ROE Portion of the
Award will be payable. Exhibit I sets forth the ROE threshold that must be
achieved if any of the ROE Portion is to be payable and the higher ROE amounts
that must be achieved if higher percentages, or the entirety, of the ROE Portion
is to be payable, with interpolation for ROE performance between those limits.

The specific EPS and ROE performance targets for the Performance Period were
established by the Committee on March 1, 2006 and are set forth on Exhibit I,
attached hereto and made a part hereof. Subject to the other terms and
conditions of the Award, payment under this Award will only be made if the
Committee certifies, following the close of the Performance Period, that the
pre-established threshold performance targets have been exceeded on the Maturity
Date and then only to the extent of the level of performance so certified as
having been achieved.

Any portion of the Award earned by reason of a Committee certification as
described above will be payable in shares of the Company’s common stock (“Common
Stock”) on or before the March 31 next following the end of the Performance
Period. The number of shares to be paid will be determined by multiplying the
number of Units set forth in paragraph 1, above, by the Total Funding
Percentage. For this purpose, “Total Funding Percentage” means the sum of the
weighted funding percentages achieved for each of the ROE and EPS performance
targets, respectively, for the Performance Period as certified by the Committee.
