     SECTION 2.08 Employee Stock Options.   On the latest of (i) the Completion
                  ----------------------
     of the Offer (ii) the first business day of January 2000 or (iii) the
     earlier of (A) 30 days after termination notice is given in accordance with
     the terms of the plan governing the Options (as defined herein) or (B) the
     date that the Option holder agrees to the treatment provided in this
     Section 2.08, each holder of then outstanding options to purchase Shares
     granted by the Company (whether or not then currently exercisable) (the
     "Options") will be entitled to receive, and shall receive, at the sole
     election of the holder of such Option in settlement of each Option where
     the amount set forth in clause (i) below is positive, a cash payment from
     the Company in an amount equal to the product of (i) the Transaction
     Consideration minus the exercise price per Share of the Option and (ii) the
     number of Shares covered by such Option.  Such payment shall be reduced by
     any applicable withholding taxes.  If and to the extent required by the
     terms of the plan governing such Options or pursuant to the terms of any
     Option granted thereunder, each of Parent and the Company shall use its
     best efforts to obtain the consent of each holder of outstanding Options to
     the foregoing treatment of such Options, including without limitation,
     giving the termination notice contemplated by the plan governing such
     Options.  The Company, acting through its Board of Directors or any
     committee thereof, shall have the right at any time or from time to time
     following the execution hereof to accelerate and vest, in full or in part,
     any and all Options not currently exercisable in full.  Effective as of the
     Effective Time, the Company, acting through its Board or any committee
     thereof, shall terminate those Options with an exercise price that is
     greater than the Transaction Consideration.
