     an amount equal to 2% of such Participant's Compensation; provided,
     however, that the participant may elect to suspend such elective
     deferral contributions, or change the amount of such elective deferral
     contributions.  Such election shall be made at such time and in

     Administrator from time to time.  A Participant may change his or her

     cease elective deferrals during the election periods established by

     any bonus payable to the Participant provided that such deferral
     election is made prior to the time the Participant receives such
     bonus.  Participant elective deferral contributions will be treated as

     Contributions made pursuant to section 4.1[a] will be allocated to
     Participants in the ratio in which a Participant's Compensation for the
     Plan Year bears to the total Compensation of all eligible Participants
     for the Plan Year.  A Participant will be entitle to share in the
     allocation of the Profit-Sharing Contribution for the Plan Year if the
     Participant completes 1,000 or more Hours of Service and is employed by
     the Company on the last day of the Plan Year.  For the first Plan Year
     of participation in the Plan, the 1,000 Hours of Service requirement in
     the preceding sentence will be prorated based on the number of days the
     Participant was employed during the Plan Year.  Compensation will be
     recognized under this Plan only from the Participant's effective date of
     participation in the Plan.

     However, Profit-Sharing Contributions for the Plan Year in which a
     Participalnt attains Normal Retirement Age, Early Retirement Age, or
     Late Retirement Age and terminates employment, or dies, will be
     allocated to such Participant regardless of the Hours of Service the
     Participant completes during such Plan Year and regardless of whether
     the Participant is an employee on the last day of the Plan Year.

        [b]  MATCHING CONTRIBUTIONS:  The Company's Matching Contribution
     will be allocated to each Participant as a percentage of such
     Participant's elective deferral contributions to the Plan for the Plan
     Year.  A Participant will be entitled to share in the allocation of
     the Matching Contribution for the Plan Year if, during the Plan Year,
     the Participant completes 1,000 or more Hours of Service and is

     employed by the Company on the last day of the Plan Year.  For the
     first Plan Year of participation in the Plan, the 1,000 Hours of
     Service requirement in the preceding sentence will be prorated based
     on the number of days the Participant was employed during that Plan
     Year.  However, Matching Contributions for the Plan Year in which a
     Participant attains Normal Retirement Age, Early Retirement Age, or
     Late Retirement Age and terminates employment, or dies, will be
     allocated to such Participant regardless of the Hours of Service the
     Participant completes during such Plan Year and regardless of whether
     the Participant is employed on the last day of the Plan Year.
