("Symbion"), effective August 23, 2007 (the "Merger"), pursuant to the Agreement and Plan of Merger dated April 24, 2007 among Symbol Acquisition, L.L.C., Symbol Merger Sub, Inc. and Symbion. In connection with the Merger, the shares listed were exchanged for the right to receive $22.35 per share in cash. Immediately before the effective time of the Merger, all unvested options became fully vested and immediately exercisable. All options with an exercise price above the merger consideration of $22.35 per share were cancelled in the Merger and no payment will be made thereon. This option was cancelled in the Merger in exchange for a cash payment equal to (1) the excess between the merger consideration of $22.35 per share over the exercise price of the option, multiplied by (2) the number of shares of common stock subject to the option. This option was replaced with a new substitute option at the time of the Merger with an exercise price of $1.50 per share and calculated in a manner that satisfies the substitution requirements of Section 409A of the Internal Revenue Code. /s/ R.
