The Company may from time to time amend or terminate, in whole or in part, any or all of the provisions of the Plan; provided, however, no such action shall adversely affect the existing or future rights or interests of any Participant under this Plan without his written consent. Any such action shall be adopted by formal action of the Board and executed by an officer, director, or person authorized to act on behalf of the Company. 4.03 Nonalienation. Except insofar as applicable law may otherwise require, (i) no amount payable to or in respect of any Participant at any time shall be subject in any manner to alienation by such Participant or Beneficiary by anticipation, sale, transfer, assignment, bankruptcy, pledge, attachment, charge, or encumbrance of any kind, any attempt to so alienate, sell, transfer, assign, pledge, attach, charge, or otherwise encumber any such amount, whether presently or thereafter payable, shall be void; and (ii) the Employer shall in no manner be liable for or subject to the debts, liabilities, contracts, engagements, or torts of any Participant or Beneficiary. 4.04 Employment Relationship.

Nothing contained in this Plan shall in any manner modify, impair, or affect the existing or future rights or interests of any Participant (i) to receive any employee benefits to which he would otherwise be entitled, or (ii) to participate in any present or future "employee benefit plan" (as defined in Section 3(3) of the Act) of the Employer. Any deferred compensation payable under this Plan shall not be deemed salary 5 or other compensation to any Participant for the purpose of computing benefits to which he may be entitled under any "employee benefit plan" of the Employer. 4.06 Relationship. Notwithstanding any other provision of this Plan, this Plan and action taken pursuant to it shall not be deemed or construed to establish a trust or fiduciary relationship of any kind between or among the Company, Participant, beneficiaries, or any other persons. The Plan is intended to be unfunded for purposes of the Code and the Act. The right of Participant and his Beneficiary to receive payment of deferred compensation is strictly a contractual right to payment, and this Plan does not grant nor shall it be deemed to grant Participant, his Beneficiary, or any other person any interest in or right to any of the funds, property, or assets of the Company other than as an unsecured general creditor of the Company. 4.07 Construction of Plan. This Plan shall be construed and enforced according to the laws of the State of North Carolina applicable to contracts made in North Carolina, without reference to doctrines of conflict or choice of laws, regardless of the Participant's domicile, and, to the extent applicable, federal law. Whenever any words are used herein in the singular or plural form, they shall be construed as though they were also used in the other form in all cases where they would so apply. The use of any gender pronoun shall be deemed to include all other genders or refer to the other gender, as the context requires.
