Attachment A

Senior Executive Severance Agreement

Amendment

WHEREAS,                         , (the “Executive”) has been selected by the
Board of Directors of the Corporation to participate in the Senior Executive
Severance Plan (the “Plan”); and

WHEREAS, the Board of Directors has, from time to time, amended the Plan
prospectively for new Executives; and

WHEREAS, the Board of Directors has approved the amendment of existing Senior
Executive Plan Agreements for the purpose of conforming certain Plan benefits
and benefit eligibility requirements to those specified by the most recent
amendment to the Plan adopted effective June 11, 2008; and

WHEREAS, the Executive hereby consents and agrees to such a conforming amendment
of his Agreement, including for the purposes of: (i) prohibiting the payment of
benefits for voluntary termination unless such resignation of employment is for
“Good Reason”, as defined herein; and (ii) modifying and reducing certain change
in control severance related benefits presently provided for in his Agreement;.

NOW THEREFORE, the Executive and the Corporation hereby agree to amend the
Executive’s Agreement as follows:

 

  1. The paragraph that immediately precedes Section A is hereby deleted and the
following is substituted in lieu thereof:

The Executive shall be entitled to the benefits provided for in this Agreement
In the event the Corporation or any subsidiary or affiliate terminates the
Executive’s employment within two years after a Change in Control. The Executive
will not receive these benefits if employment terminates by reason of death,
disability, retirement on or after normal retirement age or if the Executive
voluntarily terminates employment, unless such voluntary termination is for
“Good Reason”. Good Reason shall mean, without the Executive’s express written
consent, the occurrence of any one or more of the following:

 

  (i) The assignment of the Executive to duties materially inconsistent with the
Executive’s authorities, duties, responsibilities, and status (including
reporting relationships) as an employee of the Corporation, or a reduction or
alteration in the nature or status of the Executive’s authorities, duties, or
responsibilities from those in effect immediately preceding the Change of
Control;

 

  (ii) The Corporation’s requiring the Executive to be based at a location which
is at least fifty (50) miles further from the current primary residence than is
such residence from the Corporation’s current headquarters, except for required
travel on the Corporation’s business to an extent substantially consistent with
the Executive’s business obligations immediately preceding the Change of
Control;

 

  (iii) A reduction by the Corporation in the Executive’s base salary as in
effect on the Effective Date or as the same shall be increased from time to
time;

 

  (iv) A material reduction in the Executive’s level of participation in any of
the Corporation’s short- and/or long-term incentive compensation plans, or
employee benefit or retirement plans, policies, practices, or arrangements in
which the Executive participates, from the levels in place during the fiscal
year immediately preceding the Change of Control; provided, however, that
reductions in the levels of participation in any such plans shall not be deemed
to be “Good Reason” if the Executive’s reduced level of participation or
benefits in each such program remains substantially consistent with the average
level of participation of other executives who have positions commensurate with
the Executive’s position; or

 

  (v) The failure of the Corporation to obtain a satisfactory agreement from any
successor to the Corporation to assume and agree to perform its obligations
under this Agreement.

In the event of any of the foregoing occurrences, the Executive shall notify the
Corporation of the event constituting the basis for a termination for Good
Reason. The Corporation may then take action to cure the Good Reason event or
condition. If the Corporation does not remedy the basis for a Good Reason
termination within 30 days of receipt of notice from the Executive, the
Executive may then terminate his employment for Good Reason and qualify for the
benefits provided for in this Agreement.

The existence of Good Reason shall not be affected by the Executive’s temporary
incapacity due to physical or mental illness not constituting a Disability. The
Executive’s Retirement shall constitute a waiver of the Executive’s rights with
respect to any circumstance constituting Good Reason. The Executive’s continued
employment shall not constitute a waiver of the Executive’s rights with respect
to any circumstance constituting Good Reason.

 

-2-

--------------------------------------------------------------------------------

  2. Section A of the Agreement is amended and restated as follows:

 

  A. Lump Sum Cash Payment. On or before the Executive’s last day of employment
with the Corporation, the Corporation will pay to the Executive, as compensation
for services rendered to the Corporation, a lump sum cash amount (subject to any
applicable payroll or other taxes required to be withheld) equal to 2.99
multiplied by the sum of (a) the Executive’s current annual base salary plus
(b) the amount of incentive compensation award that would be payable to the
Executive in respect of the calendar year in which the Change in Control occurs,
calculated on the basis of target level performance. (The incentive compensation
referred to in this paragraph is that amount paid or payable under the Annual
Executive Incentive Compensation Plan, or any successor plans, of the
Corporation.) In the event there are fewer than thirty-six (36) whole or partial
months remaining from the date of the Executive’s termination to his or her
normal retirement date, the amount calculated in this paragraph will be reduced
by multiplying it by a fraction the numerator of which is the number of whole or
partial months so remaining to his normal retirement date and the denominator of
which is thirty-six (36).

 

  3. Section B of the Agreement is amended and restated as follows:

 

  B. Long Term Incentive Awards.

 

  (i) Performance Based Long Term Incentive Awards. Performance based Long Term
Incentive Awards granted under the Corporation’s 2005 Long Term Incentive Plan
(and any predecessor or successor long term incentive plan) shall vest as of the
date of the Change in Control. The value of any such award will be determined on
the basis of target level performance unless actual measured performance exceeds
target, in which case actual performance will determine vesting and award value.

 

  (ii) Vesting of Stock Options and Stock Appreciation Rights. The vesting
period for stock option and stock appreciation rights granted under the 2005
Long Term Incentive Plan (and any predecessor or successor long term incentive
plan) will be changed, effective as of the date of the Change in Control, to the
earlier of: (i) the scheduled vesting date; or (ii) the one year anniversary of
the date the award was granted. In addition, regardless of the Executive’s age
or retirement eligibility, the period to exercise stock options and stock
appreciation rights will not be less than seven months following termination of
employment.

 

  4. Section C, “Special Retirement Benefits” is hereby deleted from the
Agreement. There will be no enhancement to pension benefits by reason of a
Change in Control.

 

  5. Section D, “Other Provisions” is hereby amended as follows:

 

  (a) Subsection (i), “Insurance and Other Special Benefits” is deleted in its
entirety. The Executive’s right to extended coverage under health, life
insurance, disability and other benefit plans following termination of
employment shall be determined in accordance with the terms of such plans as
then in effect and shall not be enhanced by reason of a Change in Control. There
will be no post-termination continuation of fringe benefits.

 

  (b) Subsection (ii), “Relocation Assistance” is deleted in its entirety.

 

  (c) Subsection (iii), “Incentive Compensation” is deleted in its entirety,
provided however, that deletion of this subsection is not intended and shall not
be construed to eliminate or reduce the Executive’s right to any Annual
Incentive Compensation Plan award that may be payable in accordance with the
terms of such plan.

 

  (d) Subsection (iv), “Savings and Other Plans” is deleted in its entirety.

 

  6. Section E, “Certain Additional Payments by the Corporation” is deleted in
its entirety and replaced by the following:

 

  E. Taxes. The Executive shall be responsible for all taxes due on payments and
benefits provided under this Agreement, including any excise taxes that may be
due under Section 280G of the Internal Revenue Code. The Corporation shall
withhold taxes to the extent required by law.

 

-3-

--------------------------------------------------------------------------------

  7. The following subsection shall be added to Section G of the Agreement:

 

  (vii) Compliance with Section 409A. Notwithstanding any other provision of
this Agreement, if and to the extent that rights or payments provided here are
determined to be subject to Section 409A of the Internal Revenue Code, the
Executive agrees to make any amendments to this Agreement that may be required
to comply with Section 409A. If the Executive is a “specified employee” under
Section 409A, any payments subject to Section 409A will be deferred for six
months from the date of termination of employment, to the extent required by
Section 409A. Any deferred payments shall be credited with interest at the rate
credited to fixed income accounts in the Corporation’s Deferred Compensation
Plan.

Any capitalized terms used herein shall have the same meaning as defined in the
Agreement or Plan, as applicable. The Agreement continues in full force and
effect except for the provisions specifically amended herein.

NOW THEREFORE, the Executive and the Corporation hereby agree to amend the
Executive’s Agreement as follows:

 

  1. The paragraph that immediately precedes Section A is hereby deleted and the

The Executive shall be entitled to the benefits provided for in this Agreement
In the event the Corporation or any subsidiary or affiliate terminates the
Executive’s employment within two years after a Change in Control. The Executive
will not receive these benefits if employment terminates by reason of death,
disability, retirement on or after normal retirement age or if the Executive
voluntarily terminates employment, unless such voluntary termination is for
“Good Reason”. Good Reason shall mean, without the Executive’s express written
consent, the occurrence of any one or more of the following:

 

  (i) The assignment of the Executive to duties materially inconsistent with the
Executive’s authorities, duties, responsibilities, and status (including
reporting relationships) as an employee of the Corporation, or a reduction or
alteration in the nature or status of the Executive’s authorities, duties, or

employee benefit or retirement plans, policies, practices, or arrangements in
which the Executive participates, from the levels in place during the fiscal
year immediately preceding the Change of Control; provided, however, that
reductions in the levels of participation in any such plans shall not be deemed
to be “Good Reason” if the Executive’s reduced level of participation or
benefits in each such program remains substantially consistent with the average
level of participation of other executives who have positions commensurate with
the Executive’s position; or

 

  (v) The failure of the Corporation to obtain a satisfactory agreement from any
successor to the Corporation to assume and agree to perform its obligations
under this Agreement.

In the event of any of the foregoing occurrences, the Executive shall notify the
Corporation of the event constituting the basis for a termination for Good
Reason. The Corporation may then take action to cure the Good Reason event or
condition. If the Corporation does not remedy the basis for a Good Reason
termination within 30 days of receipt of notice from the Executive, the
Executive may then terminate his employment for Good Reason and qualify for the
benefits provided for in this Agreement.

The existence of Good Reason shall not be affected by the Executive’s temporary
incapacity due to physical or mental illness not constituting a Disability. The
Executive’s Retirement shall constitute a waiver of the Executive’s rights with
respect to any circumstance constituting Good Reason. The Executive’s continued
employment shall not constitute a waiver of the Executive’s rights with respect
to any circumstance constituting Good Reason.
