elective account. The amount of the Elective Contribution may not be less than
1% nor more than 15% of the Participant's Compensation as elected by the

and the rights of Participants concerning an investment in the stock of the
Employer are detailed in Section 4.6 below."

         4. There is added to the Plan new Section 4.6 reading as follows:

         4.6 Investment in Employer Stock.

         (a) Definitions.

          maintain all record of the Participants' accounts with respect to
          investments in Employer Stock.

               iv. Investment in Employer Stock. A Participant may elect to
          invest a portion of the Participant's Elective Contributions and
          Employer Matching Contributions made on his behalf in Employer Stock.
          Such election shall be made on forms supplied by the Trustees and

                                       2



          maintained by the Record Keeper.

         (b) Purchase and Sale of Employer Stock.

               i. Notwithstanding anything to the contrary contained in this
          Plan or the Trust Agreement, the Trustees may direct the Custodian to
          purchase shares of Employer Stock upon the receipt by the Custodian of
          contributions from the Employees pursuant to a nondiscretionary
          purchasing program developed by the Custodian to effect such purchases
          in an orderly manner without disruption of the market for such stock.

               ii. If a Participant's vested interest in the Participant's
          Accounts or a portion thereof is to be distributed on account of the
          Participant's retirement, disability, death, termination of
          employment, pursuant to a hardship withdrawal, withdrawal of a
          rollover contribution or as a result of a qualified domestic relations
          order or because of the minimum distribution rules, the Trustees will
          direct the Custodian to sell the Participant's shares of Employer
          Stock or distribute such stock in kind, at the election of the
          Participant or the Participant's designated beneficiary. If the
          Participant elects to take a cash distribution, the amount of cash to
          be distributed to the Participant attributable to the Participant's
          shares of Employer Stock, will be determined on the basis of the price
          or the average of the prices realized on the disposition of such
          shares on the day or days during the calendar month as may be
          designated by the Trustees in a uniform and nondiscriminatory manner.
          Notwithstanding the foregoing, the Custodian may net out transactions
          internally (so as not to be both a buyer and a seller on the open
          market) at the then prevailing market prices as determined by the
          Custodian.

         (c) Voting of Shares. Notwithstanding anything to the contrary
contained in this Plan or the Trust Agreement, whenever any proxies or consents
are solicited from shareholders, each

                                       3

whose account contains Employer Stock will have the right to direct the
Trustees, in writing, as to the voting of such shares. The Trustees or the
Custodian will use their best efforts to distribute or cause to be distributed
in a timely manner to each Participant or designated beneficiary a copy of the
proxy solicitation material sent to shareholders, together with a form addressed
to the Trustees or the Custodian containing confidential, written instructions
as to the manner in which said shares will be voted. If the instructions are
sent to the Custodian, the Custodian must communicate the instructions to the
Trustees. Upon receipt of such instructions, the Trustees will vote said shares
as instructed. Shares of Employer Stock as to which the Trustees do not receive
instructions will be voted by the Trustees in the proportion as shares are to be
voted pursuant to the written voting instructions received from all Participants
by the Trustees. Each Participant (or designated beneficiary) will be entitled
to one vote for each full share of Employer Stock allocated to the Participant's
accounts. Fractional shares of Employer Stock will not be permitted to vote.

         (d) Valuation. Employer Stock will be valued as of any business day of
each Plan Year based on the published valuation for such stock on the NASDAQ
National Market Exchange. Any dividends received on Employer Stock will be
reinvested and become part of the Participant's Accounts. The Record Keeper will
maintain adequate records of the cost basis of Employer Stock for each
Participant's account. The Record Keeper may time to time modify its accounting
procedures to achieve equitable and nondiscriminatory allocations among
Participants" Matching Contributions Account in accordance with the provisions
of this Plan and requirements of law.

         (e) Named Fiduciary Status\Confidentiality. Each Participant or
designated beneficiary shall be deemed to be a named fiduciary within the
meaning of Section 402(a) of ERISA

                                       4



with respect to the voting of the shares of Employer Stock as to which such
Participant or designated beneficiary has the right of direction. Directions
received from Participants or designated beneficiaries by the Trustees or the
Custodian shall be held in strict confidence and shall not be divulged or
released to any person, including employees, officers or directors of the
Employer, provided, however, that to the extent necessary for the operation of
the Plan, such directions may be relayed by the Trustees to the Record Keeper or
auditor for the Plan, which Record Keeper or Auditors is not the Employer and
