3.01 Amendment and Plan Termination

     The Company may, in its sole discretion,  terminate,  suspend or amend this
     Plan at any time or from time to time,  in whole or in part. In that event,
     Participants will vest in their benefits,  if any, hereunder  calculated in
     accordance  with Section  2.02 to the date of  termination,  suspension  or
     amendment  of the Plan.  Plan  suspension  or  termination  will not affect
     benefits being paid or benefits  which have vested.

     In the event of a Plan termination, the Board of Directors may, at its sole
     discretion,  elect any one or more of the following alternatives to satisfy
     the 



                                      -2-


     Company's  obligations  to  Participants  or  Beneficiaries   receiving  or
     entitled to benefits:

     (a)  Provide  benefit  payments in accordance  with Section 2.03.  

     (b)  Make lump sum  payments  equal to the  present  value of the  benefits
          payable under the Plan.

3.02 Not An Employment Agreement

     Nothing  contained  herein will confer upon any Participant the right to be
     retained  in the service of the  Company,  nor will it  interfere  with the
     right of the  Company to  discharge  or  otherwise  deal with  Participants
     without regard to the existence of this Plan.

3.03 No Advance Funding

     This Plan is  unfunded,  and the Company  will make Plan  benefit  payments
     solely on a current  disbursement  basis.  Nothing in the  establishment of
     this Plan is to be construed as  requiring  or  authorizing  the Company to
     create or maintain any separate fund, account or reserve to provide for the
     payment of the Company's liability to a Participant under the Plan.

     All payments hereunder shall be made from the general assets of the Company

     the Company.

     A  Participant  may  not,  either  voluntarily  or  involuntarily,  assign,
     anticipate, alienate, commute, pledge, discount, borrow against or encumber
     any benefits to which he is or may become  entitled to under the Plan,  nor
     may the same be subject to attachment or  garnishment  by any creditor of a
     Participant.

3.05 Interpretation

     This Plan is intended to qualify for exemption from Parts II, III and IV of
     the Employee  Retirement Income Security Act of 1974, as amended, as a plan
     maintained primarily for the purpose of providing deferred compensation for
     a select group of management or highly compensated employees under Sections
     201(2),  301(a)(3) and 401(a)(1) of such Act, and shall be so  interpreted.
     Subject to that  restriction,  the Committee shall have the sole discretion
     to  interpret  this  Plan and to adopt  rules  and  interpretation  for the
     application   and   implementation   of  this  Plan.   The   decisions  and
     interpretations  by  the  Committee  shall  be  final  and  binding  on all
     Participants.
