     regulatory body, is necessary as a condition of, or in connection with, the
     issuance or purchase of shares hereunder, this option may not be exercised,
     in whole or in part, unless such listing, registration, qualification,
     consent or approval shall have been effected or obtained on conditions

          other distribution with respect to the outstanding shares of Common
          Stock or other securities, the outstanding shares of Common Stock are
          increased or decreased, or are exchanged for a different number or
          kind of shares or other securities, or additional shares or new or
          different shares or other securities are distributed with respect to

          proportionate adjustment may be made in (i) the number and kind of
          shares or other securities subject to this option and (ii) the price

No adjustment shall be made under this Section 9 which would, within the meaning
               of any applicable provision of the Code, constitute a
               modification, extension or renewal of this option or a grant of
               additional benefits to the Director.

9.   Mergers, Etc.

               Act of 1933, or an opinion of counsel satisfactory to the

  The Director shall have no rights as a shareholder with respect to any shares
          which may be purchased by exercise of this option unless and until a
          certificate representing such shares is duly issued and delivered to
          the Director. No adjustment shall be made for dividends or other
          rights for which the record date is prior to the date such stock

If, as a result of a merger, consolidation, sale of all or substantially all of
          the assets of the Company, reorganization, recapitalization,
          reclassification, stock dividend, stock split, reverse stock split or
          other distribution with respect to the outstanding shares of Common
          Stock or other securities, the outstanding shares of Common Stock are
          increased or decreased, or are exchanged for a different number or
          kind of shares or other securities, or additional shares or new or
          different shares or other securities are distributed with respect to
          such shares of Common Stock or other securities, an appropriate and
          proportionate adjustment may be made in (i) the number and kind of
          shares or other securities subject to this option and (ii) the price
          for each share subject to this option, without changing the aggregate
          purchase price as to which this option remains exercisable.

     (b)  Authority to Make Adjustments.
          -----------------------------

Adjustments under this Section 8 will be made by a Committee of the Board of
     Directors appointed by the Board of Directors, whose determination as to
     what adjustments, if any, will be made and the extent thereof will be
     final, binding and conclusive. No fractional shares will be issued pursuant
     to this option on account of any such adjustments.

No adjustment shall be made under this Section 9 which would, within the meaning
               of any applicable provision of the Code, constitute a
               modification, extension or renewal of this option or a grant of
               additional benefits to the Director.

9.   Mergers, Etc.

  In the event of a consolidation or merger in which the Company is not the
            surviving corporation, or which results in the acquisition of
            substantially all of the Company's outstanding Common Stock by a
            single person, entity or group of persons or entities acting in
            concert, or in the event of the sale or transfer of all or
            substantially all of the assets of the Company, or in the event of a
            reorganization or liquidation of the Company, prior to the
            Expiration Date or termination of this option, the Director shall,
            with respect to this option or any unexercised portion hereof, be
            entitled to the rights and benefits, and be subject to the
            limitations, set forth in Section 10 of the Plan.

     (i) ninety (90) days after the occurrence of such Change in Control, and
     (ii) seven (7) months following the date of grant of each such option, and
     an option holder shall have the right, commencing at least five (5) days
     prior to such Change in Control and subject to any other limitation on
     exercise of an option in effect on the date of exercise, to immediately
     exercise any option in full, without regard to any vesting limitations, to
     the extent it shall not have been previously exercised.

11.  Withholding Taxes.
     -----------------

     The Company's obligation to deliver shares upon the exercise of this option

12.  Investment Representation; Legend.
     ---------------------------------

     (a)  Representations.
          ---------------

      (v.)    Any shares purchased upon exercise of this option be acquired for
              the Director's account for investment only and not with a view to,
              or for sale in connection with, any distribution of the shares in
              violation of the Securities Act of 1933 (the Securities Act") or
              any rule or regulation under the Securities Act.

      (vi.)   The Director has had such opportunity as he or she has deemed
              adequate to obtain from representatives of the Company such
              information as is necessary to permit the Director to evaluate the
              merits and risks of his or her investment in the Company.

      (vii.)  The Director is able to bear the economic risk of holding shares

                                      20
<PAGE>

          acquired pursuant to the exercise of this option for an indefinite
          period.

 (viii.)  The Director understands that (A) the shares acquired pursuant to the
          exercise of this option may not be registered under the Securities Act
          and if not so registered will be "restricted securities" within the
          meaning of Rule 144 under the Securities Act; (B) such shares cannot
          be sold, transferred or otherwise disposed of unless they are
          subsequently registered under the Securities Act or an exemption from
          registration is then available; (C) in any event, the exemption from
          registration under Rule 144 will not be available for at least one
          year from the date of exercise of the option and even then will not be
          available unless a public market then exists for the Common Stock,
          adequate information concerning the Company is then available to the
          public and other terms and conditions of Rule 144 are complied with.

By making payment upon exercise of this option, the Director shall be deemed to
have reaffirmed, as of the date of such payment, the representations made in
this Section 12.

    (d) Legend on Stock Certificates

      All stock certificates representing share of Common Stock issued to the
      Director upon exercise of this option which are not registered under the
      Securities Act shall have affixed thereto a legend substantially in the
      following form, in addition to any other legends required by applicable
      state law:

"The shares of stock represented by this certificate have not been registered
                under the Securities Act of 1933 and may not be transferred,
                sold or otherwise disposed of in the absence of an effective
                registration statement with respect to the shares evidenced by
                this certificate, filed and made effective under the Securities
                Act of 1933, or an opinion of counsel satisfactory to the
                Company, to the effect that registration under such Act is not
                required".

modified unless evidenced in writing and signed by the Company and the Director.
