D.            Supplements.  From time to time, supplements may be attached by amendment to and form a part of this Plan and shall be given the same effect that such provision would have if it was incorporated within the basic text of the Plan.  Such supplements may modify or supplement the provisions of the Plan as they apply to particular groups of Employees or groups of Participants, shall specify the persons affected by such supplements and shall supersede the other provisions of the Plan to the extent necessary to eliminate inconsistencies between the Plan provisions and the provisions of such supplements.

E.             Non-Resident Aliens.  With respect to non-resident alien Employees, the Committee or Plan Administrator may adopt one or more sets of procedures and provisions, which may be different than those included in this Plan for other Participants, with each set of procedures and provisions applying to some or all of such non-resident alien Employees, as determined by the Committee in its sole discretion or the Plan Administrator in his or her sole discretion, in order to comply with the applicable laws of the respective jurisdiction(s) in which

4

such non-resident alien Employees live or work and/or to take into account other legal, tax, accounting and similar issues arising by virtue of the participation of such non-resident alien Employees.  The adoption of any such procedures and provisions shall not be deemed an amendment to this Plan.

SECTION IV - PARTICIPATION

A.            Eligibility.  Any person who is or becomes an Employee may commence participation in the Plan as soon as administratively feasible on or subsequent to such individual’s date of hire; provided, however, that for purposes of the Plan, the Committee or the Plan Administrator may exclude from eligibility non-resident aliens (or classes of non-resident aliens), if any, if the requirements of local law, rules or regulations, including without limitation, the tax, labor, accounting or securities laws, rules, regulations or consequences, make participation by such non-resident aliens (or class(es) of non-resident aliens) impractical, as determined by the Committee in its sole discretion or the Plan Administrator in his or her sole discretion.

B.            Enrollment.  Enrollment in the Plan shall be accomplished by such procedures as are established by the Committee or the Plan Administrator from time to time.  Unless determined otherwise by the Committee or the Plan Administrator, Payroll Withholding Contributions will commence as of the first pay period which begins not less than ten days following a Participant’s communication of instructions to commence such contributions.  Other Permitted Contributions will be made as soon as is administratively feasible, as determined by the Committee or the Plan Administrator, following the Corporation=s receipt of instructions to commence such contributions.

Notwithstanding anything in this Section V(D) to the contrary, a Participant whose employment terminates by reason of Retirement, death or Disability prior to the end of a Two-Plan-Year-Period shall be eligible to receive a Share Retention Contribution with respect to such partial Two-Plan-Year-Period (consisting of the Plan Year during which the Participant’s employment so terminates and the immediately preceding Plan Year) if and only if there have been no withdrawals during such period (prior to termination of employment).  The Share Retention Contribution made on behalf of any such eligible terminated Participant with respect to such period shall be prorated based on the number of days during the final Plan Year that the Participant was employed and shall be net of all applicable withholding and deductions.   Notwithstanding any provision herein to the contrary, the Share Retention Contribution made on behalf of any such eligible terminated Participant shall be made as soon as reasonably practicable, but not later than the March 15th, after the first day of the Plan Year following the Plan Year that includes the Participant’s Retirement, death or Disability.

For purposes of this Section V(D), a Participant’s employment shall be considered to have terminated by reason of Retirement if he or she terminates employment with eligibility for, and elects to commence receipt of, an early or normal retirement benefit under a tax-qualified defined benefit retirement plan maintained by the Corporation, and a Participant’s employment shall be considered to have terminated by reason of Disability if he or she terminates employment with eligibility for, and is awarded, disability benefits under a long-term disability plan maintained by the Corporation.(1)

(1) Please note that determination of disability and award of disability benefits may occur retroactively long after the Participant’s employment termination date and after the date that Share Retention Contribution determinations were otherwise made for the relevant Plan Year.

SECTION VIII - WITHDRAWALS FROM PLAN

A.            In-Service Withdrawals.  A Participant may withdraw all or any portion of the balance of his or her Account from the Plan during the Participant’s employment.  Unless determined otherwise by the Committee or the Plan Administrator, if the value of the Participant’s Account at the time the in-service withdrawal is requested is less than the value of ten Corporation Shares at such time, distribution will be made to the Participant in cash.  Otherwise, the Participant may elect to receive a distribution in the form of cash or Corporation Shares.  Any brokerage commissions incurred in connection with the sale of Corporation Shares to facilitate a distribution shall be charged to the Participant’s Account.  A Participant shall not be entitled to receive a Matching Contribution with respect to any Payroll Withholding Contributions, Service Award Contributions and/or Other Permitted Contributions made during a calendar quarter if the Participant has made an in-service withdrawal during such quarter.

B.            Termination Withdrawals.  A Participant or his or her Beneficiary(ies) must submit an application to withdraw the balance of his or her account not later than ninety days after the Participant’s employment terminates due to death, Disability, Retirement, voluntary resignation, involuntary dismissal or any other reason, or within ninety days after the Participant or his or her legal representative receives notice that the Plan has terminated. A withdrawal application will be provided to the Participant or Beneficiary(ies) upon the occurrence of any of the aforementioned circumstances.  The application must be returned to the Custodian Bank within ninety days of receipt.  If the Custodian Bank does not receive a withdrawal application by the specified deadline, it will distribute the balance of the Participant’s Account to the Participant or his or her legal representative in the form of whole Corporation Shares registered in the Participant’s name; provided, however, that unless determined otherwise by the Committee or the Plan Administrator, if the value of the Participant’s Account on the date of distribution is less than the value of ten Corporation Shares at such time, the distribution will be made in cash.  If the Custodian Bank receives a withdrawal application by the specified deadline and the value of the Participant’s Account at the time the termination withdrawal is requested is less than the value of ten Corporation Shares at such time, then unless determined otherwise by the Committee or the Plan Administrator, the distribution will be made in cash.  Otherwise, the Participant or his or her Beneficiary(ies) may elect to receive a distribution in the form of cash or Corporation Shares.

Except as otherwise determined by the Committee, a Section 16 Insider shall not be permitted to receive a cash distribution from the Plan, if, within the previous six months, he or she (or any other person whose transactions are attributed to the Section 16 Insider under Section 16 of the Exchange Act) either (i) acquired Corporation Shares in the open market or pursuant to a private transaction; or (ii) made an election under the Plan (or under any other Plan sponsored by the Corporation) that resulted in an acquisition of equity securities of the Corporation within the meaning of that term under Section 16 of the Exchange Act.  The Committee or Plan Administrator may make such other rules as are necessary to comply with Section 16 of the Exchange Act, as amended from time to time.

9

Form will be effective only if it is signed by the Participant and submitted before the Participant’s death.  Any subsequent Beneficiary Designation Form properly submitted will supersede any previous Beneficiary Designation Form so submitted.  If a Participant designates a spouse as a Beneficiary, such designation shall automatically terminate and be of no effect following the divorce of the Participant and such individual, unless ratified in writing post-divorce.

If the primary Beneficiary shall predecease the Participant or the primary Beneficiary and the Participant die in a common disaster under such circumstances that it is impossible to determine who survived the other, the balance of the Participant’s Account shall be distributed to the alternate Beneficiary(ies) who survive(s) the Participant in accordance with this Plan. If there are no alternate Beneficiaries living or in existence at the date of the Participant’s death, or if the Participant has not submitted a valid Beneficiary Designation Form to the Corporation, the balance of the Participant’s Account shall be distributed in accordance with the terms of the Plan to the legal representative for the benefit of the Participant’s estate.

The Corporation reserves the right to distribute the balance of a Participant’s Account to his or her estate notwithstanding the designation of a Beneficiary, if the Corporation is unable to locate the Beneficiary, a dispute arises among Beneficiaries or under any other circumstances the Corporation deems appropriate.
