3. Participation



| | (a) |  | Each member of the Planning Group will participate in the Plan
for as long as he or she serves on the Planning Group, unless he or
she is subject to an individual contract or agreement that provides
severance or similar benefits upon termination of employment following
a Change of Control.

|
| | (b) |  | Other key executives of the Corporation or a Subsidiary, as
designated by the Chief Executive Officer from time to time in writing
also may participate in the Plan. Non-Planning Group participants
will be notified in writing of their participation in the Plan, which
may be terminated by written notice from the Chief Executive Officer
at any time prior to a Change of Control.
|
| | (c) |  | If an executives participation in the Plan or employment is
terminated prior to a Change of Control, and the Plan Administrator,
in its reasonable discretion, determines that such termination of
participation or employment was in connection with or in anticipation
of a Change of Control, then the affected individual will be eligible
for benefits under the Plan.             
|
| | (d) |  | Notwithstanding any provision of the Plan to the contrary, an
executive who is a participant in the Plan on the date of a Change of
Control will remain a participant until the earlier of the date his or
her employment terminates and all benefits to which the executive is
entitled under Section 5 have been paid or the date which is two years
after the Change of Control.      

4. Termination of Employment on or after a Change of Control

A participant will be entitled to the severance and other benefits
described in Section 5 if any of the following occurs:



| | (a) |  | The participants employment with the Corporation and all of
its Subsidiaries terminates for any reason other than cause, death
or disability within 60 days after the Change of Control. Cause

his or her duties or the willful engaging by the executive in illegal
conduct or gross misconduct materially injurious to the Corporation.

incentive compensation or material adverse change in employee
benefits; (iii) requiring the executive to be based at an office or
location more than 35 miles from the location where the executive was
based immediately before the Change of Control; or (iv) failure of the
Corporation to require any successor to the Corporation to comply with
the Plan. Determination by the executive of good reason is
conclusive if made in good faith.
|
| | (c) |  | The participants employment with the Corporation and all of its
Subsidiaries is terminated by the Corporation within two years
following the Change of Control for reasons other than cause.

5.     Obligations of the Corporation upon Termination of Employment on or after a
Change of Control

If a participants employment terminates pursuant to Sections 4 (a), (b)
or (c), the Corporation will provide the participant with the following,
subject to the participants obligations under Section 6:



| | (a) |  | The Corporation will pay the participant a lump sum cash payment
within thirty days after the date the participants employment
terminates (or the later date the participant provides the Corporation
with the agreement referenced in Section 6) consisting of: (i) unpaid
salary and earned unused vacation pay through the date of termination;
(ii) a pro-rated bonus for the year of termination based upon the
participants base bonus; (iii) the product of 2.5 and the sum of
the participants annual base salary (at the rate in effect
immediately prior to termination) and base bonus, and (iv) unpaid
compensation previously deferred by the executive (together with any
earnings thereon). Base bonus means the highest annual incentive
bonus awarded by the Corporation to the participant for the three
calendar years prior to his or her termination of employment; or in
the case of a participant who has not received an annual bonus as of
the date his or her employment terminates, the participants base
bonus shall be the minimum guaranteed bonus for the year of
employment, as established at the time of the participants hire.
Base bonus shall include the cash value of restricted shares, valued
at the date of grant without any discount for restrictions, to the

eligible for continued medical and life insurance coverage under the
Corporations plans as in effect on the participants termination of
employment, at the same cost to the participant as if the participant
had remained actively employed by the Corporation, for thirty months
after the participants date of termination; provided, however, that
if the participant is employed during this period, coverage provided
by the Corporation will be secondary to that provided by another
employer.

| | (c) |  | The Corporation will pay the participant a lump sum cash payment
within thirty days after the date the participants employment
terminates (or the later date the participant provides the Corporation
with the agreement referenced in Section 6) equal to the actuarial
value of the benefit the participant would have accrued in the
thirty-month period after the participants employment terminated, had
the participant continued to participate during that period under the
Corporations qualified and supplemental defined benefit retirement
plans (if any) as in effect on the Change of Control, based on the
assumption that the participant had earned the same compensation over
such thirty-month period as he or she had earned over the thirty-month
period preceding his or her termination of employment.

participant will become exercisable on the date the participants
employment terminates and will remain exercisable for a minimum of
three years after termination of employment or until the earlier
expiration date of the option, and restrictions shall lapse on all of
the Corporations restricted shares outstanding to the participant
effective on the participants termination of employment,

contrary.

subsidiaries.

The Corporation will reduce amounts payable or distributable pursuant to the
foregoing by any amounts necessary to satisfy its tax withholding liabilities
under applicable law.

6. Certain Additional Payments by the Corporation



| | (a) |  | In the event that any payment or distribution by the Corporation
to or for the benefit of the participant (whether payable or
distributable pursuant to the terms of the Plan or otherwise, but
determined without regard to any additional payments required under
this Section 6 (a Payment), would be subject to the excise tax
imposed by Section 4999 of the Code, then the participant shall be
entitled to receive an additional payment (a Gross-Up Payment) in an
amount such that after payment by the participant of all taxes and
excise tax imposed upon the Gross-Up Payment, the Executive retains an
amount of the Gross-Up payment equal to the excise tax imposed on the
Payment.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
| | --- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|
| | (b) |  | Notwithstanding the provisions of Section 6(a), if it shall be
determined that the participant is entitled to a Gross-Up Payment, but
that the participant, after taking into account the Payments and the
Gross-Up Payment, would not receive a net after-tax benefit of at
least $100,000 (taking into account both income taxes and any excise
tax) as compared to the net after-tax proceeds to the participant
resulting from an elimination of the Gross-Up Payment and a reduction
of the Payment, in the aggregate, to an amount (the Reduced Amount)
such that the receipt of Payments would not give rise to any excise
tax, then no Gross-Up Payment shall be made to the participant and the
Payments, in the aggregate, shall be reduced to the Reduced Amount.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
|
| | (c) |  | The participant shall notify the Corporation in writing of any
claim by the Internal Revenue Service that, if successful, would
require the payment by the Corporation of the Gross-Up Payment. Such
notification shall be given as soon as practicable but no later than
ten business days after the participant is informed in writing of such
claim and shall apprise the Corporation of the nature of such claim
and the date on which such claim is requested to be paid. The
participant shall not pay such claim prior to the expiration of the
30-day period following the date on which it gives such notice to the
Corporation (or such shorter period ending on the date that any
payment of taxes with respect to such claim is due). If the
Corporation, in its sole discretion, elects to contest such claim, the
participant must take all steps reasonably requested by the
Corporation to do so, including, without limitation, giving the
Corporation information related to such claim, cooperating with the
Corporation in good faith in order to contest such claim, permitting
the Corporation to participate in proceedings related to such claim
and accepting legal representation with respect to such claim by an
attorney reasonably selected by the Corporation. The Corporation
shall bear directly all costs and expenses associated with such a
contest.
|
| | (d) |  | If, after the receipt by the participant of an amount advanced by
the Corporation pursuant to Section 6(a), the participant becomes
entitled to receive any refund with respect to a claim pursuant to
Section 6(c), the participant shall promptly pay to the Corporation
the amount of such refund (together with any interest paid or credited
thereon after taxes applicable thereto). If after the receipt by the
participant of an amount advanced by the Corporation pursuant to
Section 6(a), a determination is made that the participant shall not
be entitled to any refund with respect to a claim under Section 6(c)
and the Corporation does not notify the Executive in writing of its
intent to contest such denial or refund prior to the expiration of 30
days after such determination, then such advance shall be forgiven and
shall not be required

Any such interpretation or determination shall be final and binding on
all parties. 
| | --- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|
| | (b) |  | No member who serves on the committee that constitutes the Plan

under the Plan (Claimant) must file his or her claim in writing with
the Plan Administrator, along with any supporting documentation,
within thirty days after the Claimants right to benefits under the
Plan arises. The Plan Administrator or its designee shall review the
claim and notify the Claimant of its decision.

|
| | (b) |  | If the claim is denied, in whole or in part, the Plan
Administrator or its designee shall notify the Claimant in writing
within a reasonable period of time following its receipt of the claim,
with an explanation of the reasons the claim is denied.                                                                                                                                                                                                                      
|
| | (c) |  | No later than 60 days following his receipt of a notice of a
claim denial, the Claimant or his or her duly authorized
representative may submit a written request for review of the claim
denial.                                                                                                                                                                                                                                                                            
|
| | (d) |  | The Plan Administrator or its designee shall make a decision on
review of a claim denial within 60 days following its receipt of a
request for review, unless special circumstances require an extension
of the time for processing, in which case the Claimant shall be
notified in writing, and the Plan Administrator or its designee shall
make a decision within 120 days following its receipt of the request
for review.                                              
|
| | (e) |  | Notwithstanding the foregoing, the Plan Administrator or its
designee may, in its sole discretion and in lieu of the procedures
described above, take whatever additional, alternative or abbreviated
action it feels is satisfactory to fully and fairly review any claim
for participation or benefits hereunder, to provide adequate written
notice of an initial claim denial or appeal and to offer reasonable
opportunity for a full and fair review of a claim denial.
|
| | (f) |  | Each Claimant must fully exhaust the claims procedures outlined
under this Section 11 before filing a claim arising under the Plan in
a court of law or similar body. The Plan Administrators decision on
review of a claim denial shall be final and binding on all interested
parties.

| | (g) |  | Upon the participants exhaustion of the claims procedures above,
the Corporation will reimburse the participant for legal fees incurred
by the participant in challenging or enforcing a Plan provision,

pay such fees.

12. Non-Duplication of Benefits

Notwithstanding anything herein to the contrary, the Corporation shall
have no obligations to pay benefits under this Plan if an executive receives
benefits under a change of control employment agreement or the termination
provisions of any other employment agreement.

13. No Right to Employment

Participation in the Plan shall not give or be construed as giving a
Participant the right to be retained in the employ of the Corporation or a
Subsidiary. Further, the Corporation and each Subsidiary expressly reserve the
right at any time to dismiss a Participant free from any liability, or any
claim under the Plan, except as provided herein.

14. Governing Law

To the extent that federal laws do not otherwise control, the Plan shall
be construed in accordance with and governed by the law of the State of
Delaware.

15. Savings Clause

This Plan is intended to comply in all aspects with applicable law and
regulation. In case any one or more of the provisions of this Plan shall be
held invalid, illegal or unenforceable in any respect under applicable law and
regulation, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby and the
invalid, illegal or unenforceable provision shall be deemed null and void;
however, to the extent permissible by law, any provision which could be deemed
null and void shall first be construed, interpreted or revised retroactively to
permit this Plan to be construed in compliance with all applicable laws so as
to foster the intent of this Plan.
