          ------------------
          Option with respect to the number of Shares indicated on or after the
          vesting date and before the last date upon which the option may be
          exercised:

                 Exercised               Exercised              Exercised
          ---------------------       -----------------       --------------
                    ___                  ___, 20___             ___, 20___
                    ___                  ___, 20___             ___, 20___
                    ___                  ___, 20___             ___, 20___
          To the extent that the Option has vested and become exercisable with
          respect to the Shares, as provided above, the Option may thereafter be
          exercised by the Optionee either as to all or any part of the Shares
          that have so vested until the last date upon which the Option may be
          exercised, as provided above. The Option may not be exercised for
          fewer than one hundred (100) Shares, or the total number of remaining
          Shares subject to such option, whichever is smaller. If the Option
          Stock becomes vested but has not been completely exercised as set
          forth in Paragraph 8 hereof on or before the last date upon which the
          Option may be

Page 3
          exercised as indicated above, such unexercised portion of the Option
          shall be forfeited and may not be exercised by the Optionee at any
          time in the future. Except as provided in Paragraphs 5 and 6 hereof,
          the Option may not be exercised at any time unless the Optionee shall
          be an employee at such time of the Company (an "Employee").
     5.   Termination of Employment. So long as the Optionee shall continue to
          -------------------------
          be an employee, the Option shall not be affected by (a) any temporary
          leave of absence approved in writing by the Company or (b) any change
          of duties, position or employment. If the Optionee ceases to be an
          employee for any reason other than death, each Option that has vested
          on or prior to the date of termination may be exercised within 90 days
          after the effective date of termination, but shall in no event be
          exercisable thereafter, notwithstanding the least date upon which the
          Option may be executed pursuant to the terms set forth in this
          Agreement. If an Option has not vested or become exercisable on the
          date of termination, such Option shall be void and cannot be exercised
          thereafter. Nothing contained in this Agreement shall confer upon the
          Optionee any right to continue in the employ of the Company, or to
          limit or interfere in any way with the right of the Company to
          terminate his or her employment at any time, with or without cause.

     6.   Death of Optionee. If an Optionee who was entitled to exercise an
          -----------------

          employee of the Company, the date on which the vested portion of the
          Option may be exercised shall be extended one (1) year. The person or
          persons that receives by will or by the laws of descent and
          distribution the right to exercise the Option (the "Personal

          rights, if any, which had accrued as of the date of the Optionee's
          death pursuant to Paragraph 4 hereof and which have not theretofore
          been exercised; provided, however, that such accrued purchase rights
          shall in any event terminate upon the earlier of the last date on
          which such option is otherwise exercisable or one (1) year from the
          date of the Optionee's death.
     7.   Adjustment of Number of Shares. In the event of any change in the
          ------------------------------
          number of outstanding Shares through the declaration of share
          dividends, share splits, or consolidations, through recapitalization,
          or by reason of any other increase or decrease in the number of
          outstanding Shares effected without receipt of consideration by the
          Company, the number of Shares then covered by the Option and the
          Option Price shall be appropriately adjusted consistent with such
          change. The determination of the Board of Directors of the Company as
          to any such adjustment shall be conclusive and binding upon the
