            Retirement Plan for Outside Directors

            On June 2, 1999, the Company Board adopted a Retirement Plan for
      Outside Directors (the "Retirement Plan"), effective as of June 1, 1999,
      the purpose of which is to provide retirement income to members of the
      Company Board who are not officers or employees of the Company (such
      members, the "Outside Directors") in recognition of their past services to
      the Company and to provide an incentive for such persons to continue to
      serve as members of the Company Board. Each Outside Director of the
      Company participates in the Retirement Plan.

            Upon a participant's ceasing to be an Outside Director, the
      Retirement Plan provides annual retirement benefits in an amount equal to
      such participant's years of service as an Outside Director (including any
      fractional part thereof) times the annual retainer paid to Outside
      Directors of the Company on the date that such participant ceases to be an
      Outside Director. If a participant has served less than 10 years as an
      Outside Director, such retirement benefit shall be reduced by multiplying
      the amount of the retirement benefit otherwise payable by a fraction, the
      numerator of which is such participant's years of service and the
      denominator of which is 10. The retirement benefits payable under the
      Retirement Plan are payable annually for 15 years unless the participant
      elects to have the present value (determined pursuant to the Retirement
      Plan) of such participant's benefits paid as a lump sum. The Retirement
      Plan also provides death benefits in an amount equal to the present value
      of the amount that would have been paid if the participant had elected to
      receive retirement benefits in the fifteen annual installments described
      above.

            The Retirement Plan provides that in the event of a Change in
      Control (as defined in the Retirement Plan), the Company shall pay in cash
      to each Outside Director, no later than the fifth day following the Change
      in Control, an amount equal to the present value of such participant's
      accrued retirement benefit under the Retirement Plan, determined as if
      such Participant ceased to be an Outside Director upon the Change in
      Control, and elected to receive his or her retirement benefit in the form
      of a lump sum cash payment. The consummation of the transactions
      contemplated by the Merger Agreement will constitute a Change in Control
      as defined in the Retirement Plan. The text of the Retirement Plan is
      attached to this Statement as Exhibit (c)(9) and is incorporated herein by
      reference. The foregoing description is qualified in its entirety by
      reference to the text of the Retirement Plan.



ITEM 9. Material to be Filed as Exhibits.

            Item 9 of the Statement is hereby amended and supplemented by adding
