           i.   Elections to defer compensation shall be filed with the Company
                at the following times:

                1.    Base salary deferral elections must be made prior to
                      December 31 of the Plan Year prior to the year in which
                      this base salary would otherwise be earned.

                2.    Incentive compensation deferrals must be made prior to
                      June 30 of the Plan Year prior to the year in which
                      payment of the incentive would otherwise be made.

                3.    A newly designated Eligible Employee may elect to defer
                      monies under this program by filing an election with the

           ii.  At the time of the deferral, the Participant shall elect:

                1.    The percentage of the deferral that is allocated to the
                      Retirement Account and, if selected, to the Fixed Period
                      Account; and

                2.    The period of deferral (of at least one year) for the
                      Retirement Account and, if selected, for the Fixed Period
                      Account; and,

     b.   The Company, in its sole discretion, may establish a separate trust
          within the Company to hold any deferrals and unfunded credited
          earnings thereon. If the Company so elects, such trust may be funded
          with assets of the Company, provided however, that such funding
          mechanism shall not place any funds beyond the reach of the general
          creditors of the Company.

          within unfunded mutual fund options selected by the Company.

               and the account values at the beginning and end of the quarter.

          filed in writing with the Administrator.

          filing a new election with the Administrator.

8.   VESTING

     a.   The Participant shall always be one hundred percent (100%) vested in
          any contributions he or she made pursuant to Section 5(a), and any

     b.   For Company contributions made pursuant to Section 5(c) the Company
          may, prior to any company contributions, establish a vesting schedule

          regardless of Section 5:

          ii.  All amounts shall be paid in full at that time.

10.  AMENDMENT OF THE PLAN

          part, provided, however, that no amendment shall be effective to
          reduce the accrued benefit under the Plan to any Participant without
          the consent of the affected Participant(s). Written notice of any
          amendment shall be given to each Participant.

11.  MISCELLANEOUS

     a.   Participants and their Beneficiaries, heirs, successors and assigns
          shall have no legal or equitable rights, interests, or other claims in

          this Plan shall be that of an unfunded and unsecured promise of the
          Company to pay money in the future.

     b.   The Company may offset any amounts payable under the Plan against any
          debts, obligations or other liabilities owed by the Participant to the
          Company at the time benefits become payable under the Plan.

          encumber, transfer, hypothecate, or convey in advance of actual
          receipt the amounts, if any, payable hereunder, or any part thereof,
          which are expressly declared to be unassignable and nontransferable.

Board of Directors. Achievement of these threshold targets will result in a
bonus payment equal to 50% of the Bonus Percentages listed above in Table I,

Achievement of the Net Sales Base Target and actual EBIT achievement at the Full
Payout EBIT Target, as established by the Board of Directors, will result in a
Bonus Payment of 100% of the Bonus Percentages listed above in Table I.

Achievement of the Net Sales Base Target and actual EBIT achievement above the
Full Payout EBIT Target, as established by the Board of Directors, will provide
an upside payment in excess of the Bonus percentages listed above in Table I.
